Women in Western Europe wore empire style robes which were made with a light and thin fabric revealing their body. To stress the silhouette of their body, they applied oil to it or sprayed water on the robe so that it would cling to the body, and most women suffered from muslin disease, meaning flu and tuberculosis of the lungs in winter season. The purpose of this paper is to examine the thermal insulation of the robe with spencer jacket in dry and wet environment through thermal manikin experiments.

Three kinds of spencer jacket were made based on historical evidence and data, and experimental work for thermal insulation was conducted using a thermal manikin. The study measured the total thermal resistance of dress-jacket set: weight of the clothing before and after wetting, thermal insulation of the spencer jackets and set of clothing in dry and wet conditions, electric power consumption of the set of clothing in the wet condition and temperature inside the clothing and surface temperature of the wet set of clothing.

The thermal insulation of the robe with spencer jacket in the wet condition was in the range of 0.135-0.144 clo, which was about 80 percent lower than the range of values of 0.73-0.79 clo measured in the dry condition. This means that women felt uncomfortable in wetting condition or raining environment even when wearing the robe with a spencer jacket. Thermal insulation of clothing was dependent to the air gap under garment, clothing layers, ventilation through fabric and body part.

In this study, the thermal insulation of an empire style robe with spencer jacket in wet condition was measured using a dry thermal manikin, not with the sweating manikin. The authors measure the electric power consumption according to drying time of the clothing set at the body parts. In order to study the effect of different materials and clothing wetting, comparison experiments were conducted in dry and wet conditions using the rinse cycle of washing machine.

The purpose of this paper is to analyze the post type of the official account of the Korean fashion brands on Instagram and to analyze the images and keywords according to the use of the hashtag in it. This study also will provide data of how fashion brands use the new media of Instagram and how they promote it.

This study investigated the types of postings and keywords of hashtag(#) of fashion brand’s official Instagram account in order to analyze the post type and keyword. In total, six apparel brand companies were selected, with two in each of three categories (classic casual brand, outdoor sports brand and designer character brand), and seven types of postings were classified (lookbook and product, collection, broadcasting ads, brand issue, sensibility pictures, sponsorship and event). The frequencies were collected according to their types that were confirmed by four fashion major specialists.

First, the proportion of the types of postings varied according to the characteristics of the brand. Second, the six brands used keywords of a symbol because it is important to convey brand identity. Third, the sensibility keywords of each brand were investigated, and one of the designer character brands used only practical keywords without sensibility keywords. Fourth, this study examined the number of Instagram hashtags and hearts to determine if the reaction was in alignment with the marketing trends of the company’s official Instagram account and consumers. One of the classic casual brands, one of the outdoor sports brands and both designer character brands showed a high proportion of types of posts on Instagram that well matched with consumer response. As a hypothesis of this study, it was supported that the posting types of images and hashtags will be different according to the characteristics of brand.

Instagram is the fastest growing social network service (SNS) globally, especially among young adults. Instagram is noted for its strong SNS marketing but it has not been well researched in the apparel industry. The study results will help improve the brand image and promotion by using official Instagram account in the apparel industry.

Empire style fashion, Greek-Roman style robe with bare shoulder and chest and short sleeved with long gloves which created a slim silhouette, was worn even in winter season in Europe, where average temperature is 0-5°C. Most women suffered with catching cold and thousands caught flu and tuberculosis of the lungs, called muslin disease. The purpose of this paper is to find out clothing insulation of the robe by measuring the thermal resistance and to guess how cold they felt in this robe in winter time.

The authors performed the investigation on original robe shape with based on historical evidence and data, such as drawings, sketches, pattern books and sewing books, and reproduced a representative robe costume and tested its thermal insulation. The fabrics of robe were thin wool, silk and cotton following the literature evidence and preserved costume. Thermal insulation of the robes was measured using thermal manikin with the test method ISO 15831. The authors analyzed the thermal insulation of reconstructed robes with an inner cotton breech as for daily use and tested them wrapped with cashmere shawl on manikin shoulder as for severe cold weather.

The dress robes had the range of 0.61-0.67 clo regardless of the type of fabric materials, and 0.80-0.81 clo with the cashmere shawl. These values were not enough for women to keep body temperature or comfort in winter time.

This study combined fashion historic theory for costume reproduction with clothing science and technology for thermal insulation. Combination of costume history, construction technology and measurement engineering is the ingenious idea, and the combination of historical and scientific research evidences interdisciplinary originality.

The COVID-19 pandemic has caused a decline in overall consumption, but luxury sales within offline department stores rose significantly. This study identifies changes in the market environment variable (i.e. pandemics) and their impact on clothing consumption behavior. Moreover, it examines consumer behavior characteristics and provides implications for future fashion marketing and merchandising strategies.

This study analyzed post-pandemic consumption trends by obtaining luxury brand sales data from the Korea National Statistical Office and department stores. Moreover, it investigated luxury consumption fluctuation after the pandemic and statistically analyzed the characteristics of luxury consumers by customer level (CL) that affected sales.

The results of the study showed that offline (online) clothing consumption at mass markets has decreased (increased) since the pandemic, whereas sales of luxury fashion brands at offline department stores have grown. Moreover, the in-depth analysis showed a significant sales decline (increase) for clothing-centered (leather-centered) luxury brands.

If such a trend in luxury brand consumption continues, current polarization is expected to be maintained. Therefore, the study’s findings can be used as basic data in strengthening luxury brands and planning products.

This is the first work to undertake a comparative study of fashion consumer behavior, before and after the pandemic, involving the mass and luxury markets in South Korea.

Given its growing economic potential and social impact, this study aims to understand the motivations and concerns regarding metaverse usage. It identifies user needs and risks around the metaverse grounded on uses and gratifications theory and perceived risk theory.

The authors analyzed user reviews and rating data from Roblox, a representative modern metaverse platform. They applied BERTopic modeling to extract topics from reviews, identifying key motivations and risk aspects related to metaverse usage. They further constructed an explanatory model to assess how those affect user satisfaction and changes in these effects over time.

This study discovered that gratifications like entertainment, escapism, social interaction and avatar-based self-expression significantly influence user satisfaction in the metaverse. It also highlighted that users find satisfaction in self-expression and self-actualization through creating virtual spaces, items and video content. However, factors such as identity theft, fraud and child safety were identified as potential detriments to satisfaction. These influences fluctuated over time, indicating the dynamic nature of user needs and risk perceptions.

The novelty of this study lies in its dual application of the uses and gratifications theory and perceived risk theory to the metaverse. It provides a novel perspective on user motivations and concerns, shedding light on the distinct elements driving user satisfaction within the metaverse. This study unravels the metaverse’s unique capacity to assimilate features from established digital media while offering a distinctive user-generated experience. This research offers valuable insights for academics and practitioners in digital media and marketing.

This research pioneers the application of both uses and gratifications and perceived risk theories to understand factors influencing metaverse satisfaction. By establishing a comprehensive framework, it explores the metaverse’s unique value as a user-content creation platform, while encompassing existing digital platform characteristics. This study enriches the academic literature on the metaverse and offers invaluable insights for both metaverse platforms and brand marketers.

This study aims to examine the effects of different types of endorsers (expert vs consumer vs celebrity) in testimonial vs non-testimonial message contexts on consumers’ responses toward direct-to-consumer advertising (DTCA).

An online experiment was conducted with a 3 (endorser type: expert vs consumer vs celebrity) × 2 (message type: testimonial vs non-testimonial) plus control group (no endorser, no testimonial) factorial design to assess the various dependent variables.

Perceived source credibility and similarity was significantly different across the endorser types, and the expert endorser (i.e. a doctor) generated the highest mean level of source credibility, while consumer endorsers generate the highest mean source similarity. The interaction of endorser type and message type significantly impacted ad believability and skepticism. Specifically, the endorser type factor had a significant impact on the dependent variables only in the testimonial ad condition, but not in the non-testimonial ad condition. The effects were mediated by source credibility.

While the focused results show celebrities may not be the strongest choice to endorse when using testimonials, the overall lack of main effect of testimonials lends to the possibility of a plateauing of effects with the various appeals used in DTC ads. DTCA has now been around for over 20 years, and this study lends to the possibility consumers are becoming unaffected by the various appeals used by pharmaceutical manufactures and only respond when a multitude of personally relevant factors are in place.

The purpose and approaches of this article differ from those of prior research in several ways. First, while existing leadership meta-analytic research has focused on the relationship between specific types of leadership and organizational correlates, this study is a comprehensive and systematic meta-study of overall leadership types and organizational effectiveness. Second, while most of the aforementioned previous leadership meta-analysis studies target various countries and organizations, this study focuses on the leadership of the police, especially the South Korean police, and organizational effectiveness. In particular, this study is necessary because leadership meta-analysis studies of police organizations are rare. Third, this study can contribute to the accumulation of leadership knowledge in the context of contingency theory. According to contingency theory, no form of leadership is effective in all situations. Both the environment and organizational factors of leadership have a significant impact on the effectiveness of leadership. In this regard, it is very meaningful to meta-analyze the studies on leadership and organizational effectiveness of the Korean police and interpret the results in conjunction with the Korean national context and the characteristics of the police.

In this study, the authors conduct a meta-analysis of the studies on the leadership and organizational effectiveness of the South Korean police. To select the literature for the meta-analysis, the authors used the Preferred Items for Systematic Views and Meta-analysis procedure. First, 254 papers were searched, of which 133 were published in academic journals and 121 were dissertations. Second, 84 studies were selected, excluding 135 double-discovered studies, 30 studies unrelated to police leadership and 5 undisclosed studies. Finally, the authors checked the abstract and content of the literature. The authors evaluated the quality of the 36 studies that were selected through the above process. The authors estimate the sample size–weighted mean correlation by reflecting the sample size of each study in the converted Fisher's z-value. The final result is presented by reverting to the correlation coefficient for convenience of interpretation. Through this meta-analytic process, the authors estimated the mean effect size of whole leadership on the organizational effectiveness of the Korean police by integrating the effect size of each study.

The findings of this study have the following theoretical and practical implications. First, the results of this study indicate that the above trends in international leadership research have been applied to the Korean police as well and that the above trends in international leadership research have been applied equally to research into the South Korean police. The authors argue that more servant leadership studies are needed on the South Korean police. Second, the results of this study demonstrate that leadership is strongly correlated with organizational effectiveness among the South Korean police as well. Leadership is also found to be significantly positively related to attitude, behavior and satisfaction among the South Korean police. These results suggest that the leadership of police managers is very important for effective organizational management and improved police performance. Third, the results indicate significant differences in the effect sizes of each type of leadership. The largest effect size is the empowering leadership (EML), almost double the smallest effect size, authentic leadership. The results of the current study also indicate that transactional leadership (TSL) has a strong correlation with organizational effectiveness. Advanced research shows a significantly smaller effect than the magnitude of the effect size in this study. The authors examine the powerful effect of EML among the South Korean police from the perspective of organizational culture and the characteristics of the South Korean police. Influenced by social culture, the South Korean police also have hierarchical characteristics and a rigid organizational culture. In addition, although the police have strong discretion due to the nature of policing, individual police officers often have to take responsibility for the consequences of police discretion.

The most significant limitation of the current study is the lack of research using meta-analysis. The meta-analysis of the study was conducted on the police leadership and organizational effectiveness of one country, Korea. This is both a strong and weak point of the study. The lack of effect size on other leadership styles except transformational leadership and TSL can make it difficult to generalize the study results. There are only four samples of effect size, so careful interpretation is needed. This is also the inherent limitation of meta-analysis. After sufficient research is accumulated, it is necessary to re-estimate the effect size in future studies. In this study, the authors found differences in the effect sizes on organizational effectiveness by leadership types among the South Korean police, but more research is needed to determine the cause of the difference. In addition, this meta-analysis has a very high level of heterogeneity. This implies the possibility of various moderators, but the current study does not consider moderators. The authors recommend a continuous study on moderators that play a role in the relationship between police leadership and leadership outcomes.

The authors’ empirical evidence once again supports the claim of leadership contingency theory that leadership is the result of the interaction of factors such as followers, leaders and organizational environments. It is difficult to conclude that the most effective leadership style among the South Korean police is EML. However, the authors’ findings can raise reasonable questions about generalized leadership effects and serve as evidence that the effects of leadership can vary across national and organizational contexts. Nevertheless, the authors can ask reasonable questions about the existence of generalized leadership effects. Furthermore, the authors’ findings can serve as evidence that the effectiveness of leadership can vary depending on cultural and organizational contexts.

Numerous studies have been conducted on leadership and organizational effectiveness. However, meta-analysis studies on the relationship between leadership and organizational effectiveness focusing on certain national police forces have been limited. In this regard, the current study conducted a meta-analysis on the correlation between leadership and organizational effectiveness for South Korean police. While existing leadership meta-analytic research has focused on the relationship between specific types of leadership and organizational correlates, this study is a comprehensive and systematic meta-study of overall leadership types and organizational effectiveness. While most of the aforementioned previous leadership meta-analysis studies target various countries and organizations, this study focuses on the leadership of the police, especially the South Korean police, and organizational effectiveness. Previous research studies on the leadership of the Korean police have not properly considered national and cultural contexts. Most of them have the same limitations, that is, they applied each leadership theories that were developed in foreign countries (especially transformative leadership and transactional leadership) to the Korean police to explain whether each leadership type has a significant relationship with organizational effectiveness. The meta-analysis of this study can contribute to existing literature by overcoming this limitation. In addition, if the authors’ results match the cultural and historical characteristics of Korean police, they can provide evidence of the potential for effective police leadership in each country. The authors can also argue that meta-analysis of police leadership in other countries is necessary.

Citizen trust in police is important in terms of citizen consent to government policies and of police achieving their organizational goals. In the previous study, improvements in police policy, organizational operation and policing activities were developed to clarify which factors influence trust in police and how trust can be improved. This research raises the question, would changes in trust in police have an impact on trust in government? In this paper, this research question is discussed theoretically and the causal relationship analyzed empirically by applying OLS, ordered logistic, 2SLS and logistic regressions.

The basic analysis methods are to apply the OLS and the ordered logistic regression. OLS regression analysis is an analytical method that minimizes an error range of a regression line. The assumptions for OLS are: linearity, independence, equilibrium, extrapolation and multicollinearity issues. These problems were statistically verified and analyzed, in order to confirm the robustness of the analysis results by comparing the results of the ordered logistic regression because of the sequence characteristic of the dependent variable. The data to be used in this study is the Asia Barometer Survey in 2013.

Trust in police and citizen perception of safety are analyzed as important factors to increase trust in the government. The effects of trust in police are more significant than the effects of control variables, and the direction and strength of the results are stable. The effect of trust in police on trust in government is strengthened by the perception of safety (IV). In addition, OLS, ordered logistic regression analysis, which analyzed trust in central government and local government, and logistic regression analysis categorized by trust and distrust show the stability.

This paper has implications in terms of theoretical and empirical analysis of the relationship between trust in police and trust in government. In addition, the impact of perception of safety on trust in police can be provided to police officers, policymakers and governors who are seeking to increase trust in government. This paper is also meaningful in that it is the microscopic research based on the citizens' survey. One of the limitations of macroscopic research is that it does not consider the individual perceptions of citizens.

The results of this paper can confirm the relationship of the virtuous cycle, which is perception of safety – trust in police – trust in government. The police will need to provide security services to improve citizens' perception of safety and make great efforts to create safer communities and society. Trust in police formed through this process can be an important component of trust in government. By making citizens feel safer and achieving trust in police, ultimately, trust in government will be improved.

The police perform one of the essential roles of government and are one of the major components of trust in government, but the police sector has been neglected compared to the roles of the economic and political sectors. These influences of macro factors are too abstract to allow specific policy directions to be suggested. If we consider trust in police, and factors that can improve trust in government, we can suggest practical policy alternatives.

This research aims to investigate the role of brand types (value brand vs premium brand) in determining review content. Specifically, this research focuses on attribute-based reviews for an innovative product and suggests that consumers of value brands tend to discuss more attributes in their product reviews than those of premium brands. Also, this research suggests that review valence and time have moderating effects on the relationship between brand types and the number of attributes discussed in a review.

This research employed a data set of online consumer reviews (N = 106,980) for wireless earbuds from Amazon.com. It extracted products' attributes from review text using Bigram analysis and measured the number of attributes discussed in a review. It then analyzed the effect of brand types (value brand vs premium brand) on the number of attributes and the moderating effect of review valence and time.

The estimation results of Poisson models reveal that reviews for value brands tend to contain more product attributes than reviews for premium brands. Interestingly, the tendency is stronger among positive (vs negative) reviews, and it decreases over time as more reviews are accumulated.

While existing studies focused on the outcomes of the review content, there was not enough investigation into the determinants of the review content. This study focuses on the number of attributes discussed in a review, a key content characteristic, and provides the first empirical evidence that review content differs by brand types of an innovative product.
