The traditional Korean society has been classified as an Eastern collectivist culture, but in the flow of globalization and digitalization along with the post-Cold War era of the 1970s, Western individualistic culture and values quickly permeated the Korean younger generation. Since rapid changes occurred within a short period of time, there may be differences in cultural self-construal between generations living in the same era. Due to this, psychological problems related to emotional expression and suppression may appear differently depending on generations. Therefore, in the current study, 1,000 Korean adult men and women from their 20s to 60s were investigated for their level of independent and interdependent self-construal, alexithymia, ambivalence over emotional expression(AEE) and emotional suppression(ES). Then the relationship between the variables(self-construal and alexithymia,) and the mediating process of AEE and ES were examined. The generation of participants were divided into the industrialization cohort (birth year < 1970) and the digitalization cohort (birth year starting from 1970). Using the PROCESS macro(Hayes, 2022), we tested a serial mediation model of AEE and ES between the relative independent self-construal(RIS) and alexithymia. The results indicate that the level of alexithymia increases by the serial increase of AEE and ES when RIS decreases. Next, we examined a moderation effect of generatione on the mediation process of AEE and ES, and found that generation moderates the relationship between ES and alexithymia. That is, the effect of ES on alexithymia is significant for the digitalization cohort, while it is not significant for the industrialization cohort. The current results imply that emotion regulation strategies of Koreans have been differently developed according to prevailing cultural values in each generation, and that the negative influence of emotion suppression could be different according to the cultural background of each generation.

This study aims at exploring the Eco-generation's perception on public libraries depending on the use of cultural programs. For this purpose, a series of in-depth interviews was conducted with public library users in the Eco-generation in order to investigated the current status of the cultural programs in public libraries and their underlying identity. The results identifies that user experience of library cultural programs did not make a meaningful difference in users' perceptions on public libraries. Furthermore, there was no meaningful difference in the perceptions on cultural programs between public libraries and other cultural organizations. A possible explaining factor to the results based on the interviews and existing research reports was identified as the lack of identity in the library cultural programs. Consequently, further studies on public libraries' identity, cooperation between research and practice in public libraries, discussion with cultural organizations in the library district, and considerations in public policy are suggested in order to strengthen the identity in the library cultural programs.

Outsourcing, importing of publishing metadata and revitalizing copy cataloging have reduced importance of traditional cataloging. Request of interoperability between other communities and business integration of related system also have changed the meaning of library catalog. Furthermore, newly declared principle and rules are totally different to existing AACR, MARC, measures to cataloging education for next generation seems to be urgently needed. In this study, firstly put together a series of discussion about future cataloging and new role of cataloging librarian, and secondly basis on it, suggest direction of cataloging education course which divided two sectors. One is for students who are undergraduated, and another is for current cataloger at working level. In basic training, it should contain principle of knowledge organization and diverse resources and its relationship, encoding scheme and its practice. The other hand, in re-education training, it should include that re-recognition about new concept of bibliographic world, changing vocabulary and encoding scheme, furthermore metadata scheme about diverse resources which library have accepted, and its integration.

Effectiveness of corporate promotion using SNS will be meaningful from theoretical and practical perspectives. This study attempts to explore the implications of running corporate ambassador programs composed of university students, different from previous studies focused mainly on celebrity influencers. To this end, the research model was generated and the hypotheses were tested by the responses of 287 subjects who received promotional messages from university student ambassadors of a public corporation. Research findings confirmed that ambassador characteristics (intimacy, expertise) had a significant influence on corporate promotion by mediating SNS information characteristics (information provision, information playfulness, and information reliability). Furthermore, it is found that MZ generation perceived the higher intimacy, the higher information playfulness, while the older generation perceived the higher expertise, the higher information reliability. In order to generalize these research findings, further research considering more diverse demographic characteristics is necessary.

Recently, with the MZ generation's entry into society and the social participation of the female population, conflicts are occurring between workplace groups that value WLB and existing groups that emphasize collaboration due to differences in work orientation. Public institutions and companies that utilize work-life balance support systems show differences in job Commitment depending on the nature of the work and the activation of the support system. Accordingly, it is necessary to verify the effectiveness of the WLB support system actually operated by the company and present universally valid standards. The purpose of this study is, first, to verify the effectiveness of the support system for work-life balance and to find practical consensus amid changes in policies and perceptions of the working environment. Second, the influence of work-life balance level and job immersion according to work characteristics was analyzed to verify the mutual influence in order to establish standards for WLB operation that reflects work characteristics. For the study, a 2X2 matrix model was used to analyze the impact of work-life balance and work characteristics on job commitment, and four hypotheses were established. First, analysis of the job involvement level of conflict-type group members, second, analysis of the job involvement level of leading group members, third, analysis of the job involvement level of agreeable group members, and fourth, analysis of the job involvement level of cooperative group members. To conduct this study, an online survey was conducted targeting employees working in public institutions and large corporations. The survey was conducted for a total of 9 days from October 23 to 31, 2023, and 163 people responded, and the analysis was based on a valid sample of 152 people, excluding 11 copies that were insincere responses or gave up midway. As a result of the study's hypothesis testing, first, the conflict type group was found to have the lowest level of job engagement at 1.43. Second, the proactive group showed the highest level of job engagement at 4.54. Third, the conformity group showed a slightly lower level of job involvement at 2.58. Fourth, the cooperative group showed a slightly higher level of job involvement at 3.80. The academic implications of the study are that it subdivides employees' personalities into factors based on the level of work-life balance and nature of work. The practical implications of the study are that it analyzes the effectiveness of WLB support systems operated by public institutions and large corporations by grouping them.

The genetic diversity and population structure of fifteen Potentilla discolor Bunge populations in Korea were determined using genetic variations at 19 allozyme loci. Fourteen of the 19 loci (73.7%) showed detectable polymorphism. Genetic diversity at the species level and at the population level was high ($H_{ES}\;=\;0.215$, $H_{EP}\;=\;0.196$, respectively), whereas the extent of the population divergence was relatively low $(G_{ST}\;=\;0.069)$. Total genetic diversity values $(H_T)$ varied between 0.0 and 0.656, giving an average overall polymorphic loci of 0.292. The interlocus variation of genetic diversity within populations $(H_S)$ was high (0.274). On a per locus basis, the proportion of total genetic variation due to differences among populations $(G_{ST})$ ranged from 0.010 for Pgm-2 to 0.261 for Pgd-2 with a mean of 0.069, indicating that about 6.9% of the total allozyme variation was among populations. Wide geographic ranges, perennial herbaceous nature and the persistence of multiple generations are associated with the high level of genetic variation in P. discolor. The estimate of gene flow based on $G_{ST}$ was high among Korean populations of P. discolor (Nm = 3.36).

As the MZ generation, who values work-life balance, became a member of the organization, leader-oriented leadership centered on goal achievement and company profit made it difficult to achieve good results in the organization in the mid-to long-term. The company must strengthen the leadership that can be helpful for the self-leadership where the members of the organization move on their own and the organizational culture that enhances the employees' job satisfaction and organizational commitment. Therefore, this study analyzed the effect of the team leader's servant leadership on the team member's self-leadership and organizational effectiveness. In addition, it was studied whether the executive officer's emotional leadership interacted with the team leader's servant leadership and had a moderating effect on the team member's self-leadership. Also, the difference in path coefficient between the MZ generation and the non-MZ generation was verified. To this end, the research model was statistically verified using the PLS (Partial Least Square) structural equation. A survey was collected from 357 team members among office workers online. As a result of the analysis, the team leader's servant leadership had a significant effect on organizational effectiveness and team member's self-leadership. Also, in the relationship between the team leader's servant leadership and the team member's self-leadership, the emotional leadership of the executive officer had a positive (+) moderating effect. The MZ generation differed from the non-MZ generation in the path where the team leader's servant leadership positively affected the self-leadership of the team member and the path where the team leader's self-leadership had a mediating effect between the team leader's servant leadership and organizational effectiveness. The results of this study will suggest various theoretical and practical implications so that executive officers, team leaders, and team members within the company can develop leadership that increases organizational effectiveness in their respective positions.
