This study aimed to examine the effects of leisure activities on leisure satisfaction and job satisfaction among airline cabin crew, as well as the mediating effect of leisure satisfaction. The context for this research was the sudden increase in air travel demand in 2022 following the COVID-19 economic recovery, which led to cabin crew members experiencing severe stress and fatigue due to excessive scheduling. To achieve this research objective, a self-administered online survey was conducted with 251 cabin crew members from domestic and international airlines, resulting in a total of 224 valid leisure satisfaction and job satisfaction, as well as the mediating effect of leisure satisfaction on the relationship between leisure activity types and job satisfaction. The hypothesis testing results revealed that all types of leisure activities, including family-oriented, friend-oriented, and work-related activities, had a significant positive effect on leisure satisfaction. Family-oriented and work-related leisure activities had a significant positive effect on job satisfaction, and leisure satisfaction had a significant positive effect on job satisfaction. Additionally, the mediation analysis confirmed that leisure satisfaction partially mediated the relationship between family-oriented and work-related leisure activities and job satisfaction, while it fully mediated the relationship between friend-oriented leisure activities and job satisfaction. Therefore, the study offers academic implications based on these findings and proposes strategies for utilizing various types of leisure activities to enhance leisure satisfaction and job satisfaction among airline cabin crew. It also suggests that future research should further validate these findings through methods such as the Delphi technique or Analytic Hierarchy Process (AHP) analysis to assess the importance and prioritization of these factors among relevant industry stakeholders.

In this study, we analyzed future emerging technologies from the perspective of convergence research and arranged them into mega-trends, trends, and issues, to carry out predictions of the future environment and search for technologies that are expected to be closely related to human life, and ultimately to achieve convergence research agenda that can predict various social problems. First, we investigated and analyzed the literature mentioned about various promising technologies and analyzed them to analyze key words and summarize the most frequently used core key words to infer trends. Then, an agenda was drawn that emphasized connectivity with the humanities-based convergence research by stratifying and organizing the inferred trends and classifying them as core and derived trends. The necessity, innovation, convergence, feasibility, future-oriented, and acceptability of these derived agendas were investigated through a survey. The analysis showed that researchers conducting convergence research showed a high interest in agenda items that deal closely with daily life with feasible technologies in the near future, while they showed a rather low interest in issues such as technology that can be realized in the distant future, terrorism or international conflicts.

This study was intended to analyze clothing preference images according to the age groups (30's, 40's, 50's and 60's) and to clarify the differences between present clothing preference images and that of the future after 60. The data was collected through a questionnaire and a total of 482 questionnaires on the age groups ranging from 30s through 60s were used in the analysis. As for the present clothing preference images in accordance with age groups, the younger age groups in the range of 30's and 40's presented higher scores in most of these images. But the older age groups in the 50's and 60's had lower scores in most of these images. On the contrary, the older age groups had higher scores than the younger age groups with respect to similar, mature, magnificent, innocent, plump and virtuous images. As for the future clothing preference images after 60 in the elegant, luxurious, graceful, intellectual, chic, urbane, slimy and sociable images, the age groups in the 30's and 40's presented higher scores than the age groups in the 50's and 60's did. However, with respect to the youth-oriented images such as fashionable, innocent, remarkable, cute and vigorous images, the age group in the 60's had a higher score than the age group in the 30's, 40's and 50's did. There were differences between the present clothing preference images and future clothing preference images after 60. The 30's and 40's presented distinctively different clothing preference images in the present and future after 60. Thus, distinct images were pursued in the older age group. The 50s showed closest images to that of the older age group, presenting more conservative inclination in clothing preferences.

This study provides analysis of the effectiveness of domestic marketing strategies of the Korean coffee shop "Caffe Bene". It bases its evaluation on statistical outputs of 'choice attributes,' "market segmentation," demographic characteristics," and "satisfaction differences." The results are summarized in four points. First, five choice attributes were extracted from factor analysis: price, atmosphere, comfort, taste, and location; these are related to coffee shop selection behavior. Based on these five factors, cluster analysis was conducted, with statistical results classifying customers into three major groups: atmosphere oriented; comfort oriented; and taste oriented. Second, discriminant analysis tested cluster analysis and showed two discriminant functions: location and atmosphere. Third, cross-tabulation analysis based on demographic characteristics showed distinctive demographic characteristics within the three groups. Atmosphere oriented group, early-20s, as women of all ages was found to be 'walking down the street 'and 'through acquaintances' in many cases, as the cognitive path, and mostly found the store through 'outdoor advertising', and 'introduction'. Comfort oriented group was mainly women who are students in their early twenties or professionals, and appeared as a group to be very loyal because of high recommendation to other customers compared to other groups. Taste oriented group, unlike the other group, was mainly late-20s' college graduates, and was confirmed, as low loyalty, with lower recommendation activity. Fourth, to analyze satisfaction differences, one-way ANOVA was conducted. It shows that groups which show high satisfaction in the five main factors also show high menu satisfaction and high overall satisfaction. This results show that segmented marketing strategies are necessary because customers are considering price, atmosphere, comfort, taste, location when they choose coffee shop and demographics show different attributes based on segmented groups. For example, atmosphere oriented group is satisfied with shop interior and comfort while dissatisfied with price because most of the customers in this group are early 20s and do not have great financial capability. Thus, price discounting marketing strategies based on individual situations through CRM system is critical. Comfort oriented group shows high satisfaction level about location and shop comfort. Also, in this group, there are many early 20s female customers, students, and self-employed people. This group customers show high word of mouth tendency, hence providing positive brand image to the customers would be important. In case of taste oriented group, while the scores of taste and location are high, word of mouth score is low. This group is mainly composed of educated and professional many late 20s customers, therefore, menu differentiation, increasing quality of coffee taste and price discrimination is critical to increase customers' satisfaction. However, it is hard to generalize the results of study to other coffee shop brand, because this study have researched only one domestic coffee shop, Caffe Bene. Thus if future study expand the scope of locations, brands, and occupations, the results of the study would provide more generalizable results. Finally, research of customer satisfactions of menu, trust, loyalty, and switching cost would be critical in the future study.

As a professional occupation, landscape education focuses on fostering professional human resources and is one of the major axes of the landscape industry. In this study, a survey of landscape students on their learning and pedagogics was conducted with the aim to present basic information for the improvement of teaching on landscape construction. A total of 348 people answered 14 questions in the category of the impression of landscape construction classes included in the questionnaire. The results showed that the students found landscape construction classes academically important and recognized the necessity for completing these classes, but they were not satisfied with the learning environments and pedagogics used in these classes. They found what they learned not readily applicable to actual practice and saw these classes as part of their preparations for the landscape engineer qualification test. Their demands in relation to the classes included field practice-oriented teaching and participation in various programs for field practice, which highlights the necessity for human resource management-oriented classes that cover planning, design, construction, and management. Challenges in relation to field practice included the provision of environment, for example offering a variety of opportunities and improving treatment in practice. This study has significance in that it analyzed the views of students and discussed directions for future improvement since there is a lack of studies and discussions about education in the field of landscape construction. This study also has a limitation that only four-year universities were included in the study. Comprehensive studies including investigating junior college and graduate school curricula and case studies of landscape construction curricula overseas are needed in the future.

Interest in smart parks has been increasing due to the recent rapid rise of smart cities, but concerns are growing over the development of technology-oriented smart parks. The purpose of this study is to evaluate the relative importance of park services through Focus Group Interviews and the Analytic Hierarchy Process (AHP) to develop user-oriented smart parks in the future. To this end, literature on park functions and services was reviewed, and interviews with experts in the field of landscape architecture and IT were conducted to derive service items. The AHP model consisted of four values, and 15 park services were established and used to survey 38 landscape experts. As a result, services for improving the park's essential functions, such as contact with nature, relaxation, and exercise-walking, were deemed important. Services related to the environment and safety in response to climate change, such as the amelioration of pollution and heatwaves were also high. The importance of social integration services was relatively low, but it was considered an important service to when enhancing community participation. Future smart parks should enhance the health benefits of contact with nature rather than implementing excessive artificial facilities and technology. Additionally, smart technology will need to be applied based on users' needs while reflecting local characteristics. Efforts should be made to enhance user intimacy and improve the understanding of smart parks by strengthening public relations education.

The 4^th Industrial Revolution (FIR) has already begun. Corporations have to fulfill their social responsibilities to the FIR. This study explores the leadership and attitudes required in the FIR era for companies to fulfill their social responsibilities. In the FIR era, workers should have certain attitudes, such as self-efficacy, expectancy, and acceptance of change. If workers have these attitudes, they will be able to make a difference in the future. This study suggests the leadership styles that are needed to improve these attitudes. Participation, creativity, delegation of leadership, and inspirational motivation of leaders involves organizational change and improvement of organizational performance. This paper demonstrates the kind of leadership that is more important for each attitude through statistical analysis. Furthermore, when workers have these attitudes, not only the future, but also their current performance can be improved. To explain this relationship, the paper describes the effect of attitudes on job satisfaction. If workers have certain attitudes, their current and future performance will improve. As a result of the research, all four leadership styles had positive effects on attitudes toward FIR, and attitudes showed a mediating effect on the relationship between leadership styles and job satisfaction. In addition, it has been proven that the role of participative and delegating leadership, which is more member-oriented leadership, is more important. Leadership will enable workers to have a particular attitude through member-centered leadership, and workers will be able to increase current and future performance. Through these efforts, companies will be able to increase their performance in the current and FIR era, and fulfill their social responsibilities more faithfully. Therefore, in the FIR era, companies will play an important role in the development of society, and create new values.

PMN-PZT films with thickness of $5\;{\mu}m$ were deposited on $Pt/Ti/SiO_2/Si$ substrate at room temperature using aerosol deposition process. The films showed fairly dense microstructure without any crack. XRD and TEM analysis revealed that the films consisted of randomly oriented nanocrystalline and amorphous phases. Post-annealing process was employed to induce crystallization and grain growth of the as-deposited films and to improve the electrical properties. The annealed film showed markedly improved electrical properties in comparison with as-deposited film. The film after annealing at $700^{\circ}C$ for 1h exhibited the best electrical properties. Dielectric constant $(\varepsilon_r)$, remanent polarization $(P_r)$ and piezoelectric constant $(d_{33})$ were 1050, $13\;{\mu}C/cm^2$ and 120 pC/N, respectively.
