The purpose of this paper is to ascertain the status of recent Korean four-year college students’ acquisition of vocational qualification certificates (hereinafter “certificates” or “qualifications”), the factors that influence certificate acquisition, and the resulting employment and wage effects.

Regression analysis was conducted on the data from the Graduates Occupational Mobility Survey.

The results showed that females and medicine and education majors had higher rates of vocational qualifications, as did the students in provincial as compared to metropolitan areas and students with high grades. In terms of effects on labor market outcomes, vocational qualifications exert a moderate degree of positive influence on employment rate, wage at the time of initial employment, and current wage (i.e. there is a persistent wage effect).

This study will provide policy implications to decrease youth unemployment in Korea and worldwide as well as to build employment services supporting the acquisition of vocational qualifications across various disciplines.

The rapid proliferation of digital devices, population aging, and acceleration of digital technology adoption due to the COVID-19 pandemic have increased the need for information education for older adults to prevent inter-generational conflicts and digital alienation. This study aims to analyze the information technology (IT) education programs provided to older adults by age group, considering their heterogeneity.

This study identifies IT education programs provided by public institutions in Seoul and target age groups (50 and above) through a survey using triangulation, which were then sorted and summarized into 27 keywords. Correspondence analysis was conducted using the keywords derived for the programs and age groups.

IT education programs in the age group 60 and above accounted for 75.2% of the programs offered, which increased to 90% when including those aged 55 and above. Particularly, the perceptual map created based on relationship correlations indicates which IT education program keywords matched each age group. The Seoul Metropolitan Government primarily offered these programs for older adults aged 60 and above, with 5–7.5 times more education programs for those aged 60 and above than for those aged 50 and above or 55 and above. Therefore, IT education must be more evenly provided to more diverse age groups among older adults to reflect the current situation.

This study contributes to the literature by proposing a future direction for IT education of older adults. Moreover, it has implications for the direction of IT education to target various age groups in IT education programs, thus enabling older adults to effectively enhance their digital literacy skills during the rapid digitalization caused by COVID-19.

The purpose of this study is to analyze two global brands (i.e. Benetton and Tommy Hilfiger) and one Indian brand (i.e. Wills Lifestyle) in terms of general brand impression, brand specific associations and brand commitment. In addition, the study investigates how the regional differences in India and Indian consumers' affinity towards global brands influence the consumer-brand relationships.

The research framework has been developed based on consumer-brand relationship theory. The consumer–brand relationship is an important indicator of the success of brands, especially when brands attempt to expand to other markets (Roper and Parker, 2006; Bastos and Levy, 2012). Three brand types were chosen for this study. The choice of the US global brand is Tommy Hilfiger, the European global brand is United Colors of Benetton, and the Indian domestic brand is Wills Lifestyle. The study utilized a repeated measure (split-plot) design involving more than two independent groups. A split-plot analysis of variance analyses a design in which a repeated measure (i.e. within subjects) factor is crossed with a between-subjects (i.e. treatment variable) factor.

The results confirm the importance of global brands over local brands in the Indian apparel consumer market. This study also examined how Indian consumers' affinity for global brands influences their evaluation of the global brands and the local Indian brands.

The study expands the literature on Indian consumer brand preferences through the investigation of three brands. The theoretical background of the study is the consumer-brand relationship theory that explains the importance of consumer–brand relationship when brands attempt to expand to other markets.

The purpose of this study is to use the individual blade pitch control (IBC), reduce actively both the rotor hub vibratory loads and airframe vibration responses for the lift-offset compound helicopter at a high-speed flight condition.

The Sikorsky X2 technology demonstrator (X2TD) is used as the lift-offset compound helicopter. The X2TD lift-offset rotor is modelled and its rotor hub vibratory loads at a flight speed of 250 knots are predicted using a rotorcraft comprehensive analysis code, CAMRAD II, and the airframe structural dynamics is represented with a finite element analysis code, MSC.NASTRAN. When the propulsive trim methodology is applied for rotor trim, the best input condition for IBC using multiple harmonic inputs is searched to reduce the rotor vibration, while the rotor aerodynamic performance (the rotor effective lift-to-drag ratio) is improved or maintained at least. Finally, the reduction in airframe vibration responses is investigated when the best input condition for IBC with multiple harmonics is applied to the lift-offset rotor.

When the IBC with the single harmonic input using the 2/rev actuation frequency, amplitude of 2° and control phase angle of 120° (2P/2°/120°) is considered for X2TD rotor, the rotor vibration is reduced by about 26.37% only and the rotor effective lift-to-drag ratio increases slightly by 0.98%. When X2TD rotor uses the IBC with multiple harmonic inputs (2P/2°/45° + 5P/1°/90°), the rotor hub vibratory loads and airframe vibration responses are reduced by 44.69% and from 0.48 to 79.10%, respectively, while rotor effective lift-to-drag ratio is improved by 0.77%, as compared to the baseline without IBC.

This study is the first study to use the 2/rev actuation for IBC to the four-bladed lift-offset coaxial rotor and to investigate to obtain simultaneously the rotor vibration reduction, rotor performance improvement and airframe vibration reduction, using IBC with multiple harmonic inputs.

The purpose of this study is to investigate the structural relationships among organizational culture, human resources (HR) practices and female managers’ organizational commitment and job satisfaction in South Korea.

Using data obtained from the Korean Women Manager Panel, 230 responses were analyzed using structural equation modeling.

The findings indicated that organizational culture directly affected HR practices and indirectly affected job satisfaction and organizational commitment. In addition, HR practices directly influenced job satisfaction and organizational commitment and indirectly affected organizational commitment through job satisfaction. Finally, job satisfaction had a direct and significant effect on organizational commitment.

The authors provide an empirical analysis of how organizational culture and functional factors influence organizational commitment and job satisfaction for female managers in the Korean context. The findings of this paper are expected to encourage scholars to pay more attention to the connection between organizational support and HR interventions to improve female managers’ commitment and satisfaction within organizations by emphasizing the alignment between organizational culture and HR practices.

An increasing number of students delay graduation or graduate without a job, because they are not ready to make a career decision. In addition, the growing number of young adults who are not in education, employment or training (NEET) has become a social concern in South Korea. To facilitate career decision-making of undergraduates, this study examined the effects of work value orientation and academic major orientation on career decision-making self-efficacy (CDMSE). The purpose of this paper is to examine the relationships among South Korean undergraduates’ intrinsic work value orientation, extrinsic work value orientation, academic major satisfaction and CDMSE.

Based on the literature review, this study tested a research model using structural equation modeling with survey results of 217 undergraduates.

The research results indicated that intrinsic work value orientation influenced academic major satisfaction and CDMSE. However, extrinsic work value orientation turned out to influence neither academic major satisfaction nor CDMSE. Academic major satisfaction also seemed to affect the CDMSE of the students in this study.

This study contributes to the field of career development by explaining the significance of undergraduates’ intrinsic work value orientation and academic major satisfaction on career decision-making. Whereas most research has focused on the effects of CDMSE, this study investigated the factors that influence undergraduates’ CDMSE.

The purpose of this paper is to outline a framework for marketing cultural goods (e.g. music) to global markets by examining modes of entry and positioning strategies used by media producers of the South Korean music industry.

An historic analysis was implemented to investigate the modalities and structures through which cultural products are produced and disseminated. Data for this study came from 314 articles collected from www.allkpop.com, a leading English-language, South Korean popular culture news site.

The cultural technology framework consists of the institutionalization of cultural technology, exportation of cultural content, collaborations with local talent, and joint ventures with local markets.

The findings emerge from an analysis of South Korean popular music industries, and further research is needed to generalize the results across cultural industries.

The cultural technology framework can be applied to cultural industries such as music, film, comics, and art, where culture and language could be barriers to adoption.

This study outlines a framework for the modes of entry and positioning strategies of cultural goods (e.g. music) in international markets. Extant literature has examined global marketing from the purview of durable consumer goods and brands, with limited insights into cultural products. More broadly, this paper addresses the call for more qualitative inquiry into international marketing topics.

The purpose of this paper is to explore the dynamics of an online community by examining its participants’ centrality measures: degree, closeness, and the betweenness centrality. Each centrality measure shows the different roles and positions of an individual participant within an online community. To be specific, this research examines how an individual participant’s role and position affects her/his information sharing activities within an online community over time. Additionally, it investigates the differences between two different online communities (a personal interest focussed community and a social interest focussed community), in terms of the interaction patterns of participants.

For this research, the authors collected log files from Korean online discussion communities (café.naver.com) using a crawler program. A social network analysis was used to explore the interaction patterns of participants and calculate the centrality measures of individual participants. Time series cross-sectional analysis was used to analyze the effects of the roles and the positions on their information sharing activities in a longitudinal setting.

The results of this research showed that all three centrality measures of an individual participant in previous time periods positively influenced his/her information sharing activity in the current periods. In addition, this research found that, depending on the nature of the discussion issues, the participants showed different interaction patterns. Throughout this research, the authors explored the interaction patterns of individual participants by using a network variable, the centrality, within a large online community, and found that the interaction patterns provided strong impact on their information sharing activities in the following months.

To investigate the changes of participant’s behaviors, this study simply relies on the numbers of comments received and posted without considering the contents of the comments. Future studies might need to analyze the contents of the comments exchanged between participants, as well as the social network among participants.

Online communities have developed to take a more active role in inviting public opinions and promoting discussion about various socio-economic issues. Governments and companies need to understand the dynamics which are created by the interactions among many participants. This study offers them a framework for analyzing the dynamics of large online communities. Furthermore, it helps them to respond to online communities in the right way and in the right time.

Online communities do not merely function as a platform for the free exchange and sharing of personal information and knowledge, but also as a social network that exerts massive influence in various parts of society including politics, economy, and culture. Now online communities become playing an important role in our society. By examining communication or interaction behaviors of individual participants, this study tries to understand how the online communities are evolved over time.

In the area of online communities, many previous studies have relied on the subjective data, like participant’s perception data, in a particular time by using survey or interview. However, this study explores the dynamics of online communities by analyzing the vast amount of data accumulated in online communities.

Corporate social responsibility (CSR) decoupling indicates a misalignment between how firms report CSR and what firms actually practice with respect to CSR. The purpose of this paper is to examine the relationship between CSR decoupling and financial performance and the factors affecting this relationship.

This paper collects and combines secondary panel data from multiple sources of Chinese listed firms from 2008 to 2020 to test the direct impact of CSR decoupling on firms’ financial performance and the moderating role of customer structure and operational slack.

This paper finds that CSR decoupling is negatively associated with firms’ financial performance. These findings further suggest that the negative relationship can be suppressed by customer stability and operational slack, but amplified by customer concentration. These conclusions remain robust to alternate measures of independent and dependent variables and narrower samples.

In the literature, the effect of CSR on firms’ financial performance is inconclusive. This is the first study to examine the impact of CSR decoupling on firms’ financial performance and the factors affecting this relationship. This paper contributes to the CSR decoupling literature from an operations and supply chain management perspective.

This paper investigates a retrospective on the Journal of Derivatives and Quantitative Studies (JDQS) on its 30th anniversary based on bibliometric. JDQSs yearly publications, citations, impact factors, and centrality indices grew up in early 2010s, and diminished in 2020. Keyword network analysis reveals the JDQS's main keywords including behavioral finance, implied volatility, information asymmetry, price discovery, KOSPI200 futures, volatility, and KOSPI200 options. Citations of JDQS articles are mainly driven by article age, demeaned age squared, conference, nonacademic authors and language. In comparison between number of views and downloads for JDQS articles, we find that recent changes in publisher and editorial and publishing policies have increased visibility of JDQS.
