This study, a research project, aims to examine the distinct characteristics of the Fourth Industrial Revolution (4IR), with a focus on construction. Following this examination, the paper presents a field study to evaluate the impact of the 4IR on the construction process.

The first half of this project is dedicated to defining the 4IR by reviewing existing literature. The other half of the project presents a case study to demonstrate the concept of the 4IR and measure the effect of its application. To validate the defined concept of the 4IR, the study focuses on the following: autonomous system for producing drawings and robotics in construction.

The intensive literature review revealed three unequivocal features of the 4IR: defined tasks, undefined tasks and improvement possibilities. The following case study showed that the incorporation of the three 4IR features resulted in improved productivity and efficiency during the construction of the podium for the Lotte World Tower. For example, the macro-based autonomous system achieved 5.52 shop drawings per hour, highlighting the potential impact of independent, autonomous machinery.

The originality of this project stems from its attempt to quantify the effectiveness of applying autonomous technologies to a practical project. While previous works in this field have focused on system development and improvement, this paper presents an autonomous system at work in an actual project, in which junior engineers were able to be entirely replaced. The system was successful in independently creating numerous required shop drawings. The value of this analysis is to generate scientific evidence to evaluate the efficacy of the adoption of 4IR-oriented technologies.

This study aims to introduce the Youth Jeonse Rental Housing Program using the unique characteristics of the Korean housing market to explain its theoretical value in the current theoretical landscape of public housing and to identify the effect of the program on the regional housing price.

This study uses three hedonic price models on the basis of Korea’s housing market, namely, own, jeonse and rent models. Moreover, it uses the hierarchical linear model to include both house- and region-level variables.

Analysis shows that youth rental housing has no effect on falling prices in the region unlike long-term rental housing. Thus, the policies using regional tenure system are more effective in the social mix than existing public housing policies.

This study introduces the program using Korea’s unique tenure system called jeonse, arguing its advantages for the supplier, recipients and regional neighborhoods. Suppliers can easily provide affordable housing at a low economic and administrative cost, whereas recipients can easily mix socially, have broad housing choices and a fighting chance for a stable life. Additionally, this policy has a low negative impact on the region. Furthermore, this study theoretically presents the potential for mixed paths other than demand or supply policies. It introduces and analyzes special policy objectives for youth housing problems.

The purpose of this paper is to focus on a potential tradeoff between security and usability in people’s use of online passwords – in general, complex passwords are secure and desirable but difficult to use (i.e. difficult to memorize) whereas simple passwords are easy to use, but are insecure and undesirable. Construal level theory (CLT) explains how high vs low construal level causes people to focus on “desirability” vs “feasibility” of an action, which in the research context can translate into the “security” vs “usability” of using passwords.

The authors conducted a series of three laboratory experiments manipulating people’s construal level and investigating its impact on password use.

The authors found that people who were induced to think at a high construal level created or showed intention to choose stronger passwords relative to people who were induced to think at a low construal level. Furthermore, this effect was also significantly different from the control group who did not receive any experimental treatment. In addition, the authors found that perspective taking targeted at the desirability of creating a strong password further strengthened the effect of a high construal level on intended password choice.

This research makes several contributions to existing literature on password security. First, this research offers CLT as a theoretical lens to explain an individual’s thinking and behavior concerning online password use. Second, this research offers empirical evidence that a high construal level improves users’ password use, a desirable feature for improved security. Third, this research contributes to the literature on how to apply nudging to influence human behavior toward more desirable, stronger, password use. Finally, our research identifies PT as a factor enhancing the positive effect of a high construal level on online users’ password use.

Along with the acceleration of Chinese urbanization, urban history degrades at a rapid rate, and development follows formalism. Based on architectural typology, this study introduces a methodology of concept mapping and discusses the urban complex design method from a perspective of regional cultural elements. The theoretical analysis shows that concept mapping represents an integrated solution that incorporates regional cultural elements into architectural planning. Through the concept mapping method, it not only protects the physical environment, but also strengthens modern urban residents’ psychological sense of belonging to their own living space. Meanwhile, distinct regional cultural elements can be efficiently combined in the overall layout, monomer building design, building details design, and landscape design of urban complex by using different architectural design methods. This design method is validated using an actual case in Guizhou. Therefore, it forms a complete set of design method with a three-step framework, namely positioning cultural areas, summarizing regional cultural elements, and selecting the mapping method and combination mode.

Graphene, which has abundant availability in nature, is currently under research for its functional applications in the field of textiles. The sp² Hybridized 1-atom-thick planar sheet has been under consideration for its unique electrical, mechanical and thermal properties, but there exists a void for aggregated data on the findings of other co-functional properties attained by the material using graphene oxide (GO) finish. This paper aims to define the techniques of extraction of GO, method of its application on textile material followed by detailed evaluation of the differential functional properties achieved.

The methodology used to explain the multiple functionalities of GO finish have been carried out by starting with the chemistry of graphene and the isolation of GO from graphite, followed by the techniques for its application on the textile along with the study on the induced functional properties that may aid to increase its potential applications.

It has been observed that with the aid of optimization of GO finish, the finish in lieu with the conductive potentialities may further provide with many essential properties such as hydrophobicity, ultraviolet protection and antibacterial property.

The field of research on GO finish is naive and except few properties, many functionalities are still unexplored that may enable its smooth production, handling and expanding its area of application. The agglomeration of scattered findings on the achievable functional properties of GO on various textiles has been achieved in this paper.
