I tried here to interpret german fairy tale "Three Dogs" from the aspect of analytical psychology. A poor young shepherd will be 'hero'accidently while wandering the world to find good luck. When he was exhausted and frustrated in wandering life, a stranger appeared before him. A stranger offered barter. So he exchanged three sheep with three black dogs which a stranger had. One dog can bring the food. Another dog can tear everything. The last one can break even steel and iron. After that, shepherd led a satisfactory wandering life. On the way, he met a sad princess who should sacrifice herself for the piece of the country to the dragon which swallows a young girl yearly. But the strong black dog which tears everything, killed the dragon and saved the princess from the sacrifice. After that, a young shepherd promised princess to come back to her after three years of wandering life. In the meanwhile a horse driver played hero false. But the princess couldn't reveal the truth because of the threat of horse driver. Three years later, the young shepherd appeared in the castle. But the true hero was caught in the prison and finally cried out the strongest dog and succeeded in escaping from the prison. And with help of another dog which bring food to him, he could meet the princess and finally married her. So they lived happy life for a long time. But he remembered the poor younger sister. So he wanted to live together with her. After that, three dogs left him with saying, they stayed to see whether he shares his good fortune with his younger sister. Then they turned into birds and disappeared in the air. In this fairy tale can we find many important symbols. With the amplification of symbols and the interpretation of this fairy tale in terms of Jung's analytical psychology, I tried to find the meaning of individuation process in this fairy tale. Hero kills the dragon which could symbolize negative mother archetype. After overcoming the negative mother complex, he could get princess which could be expressive of Anima. This marriage could symbolize coniunctio oppositorum, an important process in individuation. Each fairy tale tells us the individuation process in a different way. And the fairy tale works always in our mind with plain, simple, pure, crystal like nature. Through it can we take precious treasure like wisdom for life.

This study aimed to examine the morphological characteristics and variation in main traits by comparing the growth of individuals of Ecklonia cava Kjellman(Laminariales, Phaeophyceae) under an aquaculture environment. This survey was conducted from April 2018 to November 2019 at the aquafarm in Jindo-gun, Jeollanam-do(South coast of Korea). To classify the morphology of individuals in the aquaculture farm of E. cava, we investigated fourteen morphological characteristics and calculated four ratios between the measured values. Juvenile individuals showed a simple or oblong lanceolate, and at 3-4 months, a short stipe and holdfast developed, along with a bladelet that developed into the secondary blade form. At 5-7 months, secondary blades were found to develop irregularly on the primary blade. At 8-10 months, the primary blade expanded and secondary blades elongated. At 11-12 months, the secondary blades became oblong. At 13-14 months, the thallus area expanded. At 15-16 months, tertiary blades were formed, the thallus became more complex, the stipe thickened, and the holdfast widened. At 17-18 months, secondary blades clearly developed along with lobes. At 19-20 months, tertiary blades developed and became similar to mature natural blades. In the principal component analysis (PCA), the monthly population of the first year(Q1) and that of the second year(Q2) of the cultured population were divided along PC1, which is related to secondary blade morphological characteristics and the holdfast width. Q2 and natural populations are distributed in descending order of volume in Jeju(J), East Coast(E), and South Coast(S) along PC2, which is related to primary blade and stipe morphological characteristics. The results of this study were judged to offer important criteria for the development of different varieties of E. cava.

Research Objective : The study aimed to investigate the satisfaction with the operation of theological university curricula from the perspective of learners experiencing the theological education curriculum in the field. The goal is to provide a basis for reflective introspection on the current theological education curriculum and for restructuring it to have influential impacts within the church and society. Content and Methodology : A survey was conducted with 80 learners currently enrolled in undergraduate, graduate, master's, and doctoral programs at a theological university to analyze satisfaction with current theological education programs. To interpret the survey results progressively, in-depth interviews were conducted with a randomly selected group of 6 participants. Survey Results : First, the satisfaction with the current theological education programs was found to be 60%, indicating a high level of satisfaction. Second, while 77.5% recognized the need for practical pastoral education, only 45.5% reported that practical pastoral education is currently provided in theological education programs, indicating a lower percentage than the perceived need. Third, 73.7% responded negatively regarding whether the current theological education programs can enhance pastoral competence for future society. Lastly, the areas identified as urgently requiring change for the restructuring of theological education programs were theological education content, methodology, and objectives, in that order. Conclusion and Recommendations : In an era of great transformation, our society is changing rapidly. In the face of this wave of change, the theological education curriculum also requires adaptation to suit the new era. Traditional theological education courses have primarily focused on imparting theory-centered knowledge. However, theological education in the new era necessitates a curriculum that enhances the pastoral capacity of churches and pastors to dynamically navigate through this era of significant transition. To achieve this, it is imperative to restructure the curriculum to one that is more closely related to the pastoral field. This involves offering a variety of constructivist-based, learner-centered teaching and learning methods within a theory-centered curriculum and methodology. Additionally, it entails establishing a practice-oriented theological school that can actively address the evolving pastoral landscape in this era of great transition. Restructuring of the process is essential to meet these goals.

The aim of this research was to investigate the effect of gibberellin on improving seedling growth characteristics and enhancing strawberry quality in cutting propagation. Cuttings of the cultivar 'Seolhyang' were treated with GA₃ for 30 and 60 minutes at concentrations of 50, 100, and 150 mg·L^-1, with distilled water used for dipping as the control. Evaluation of seedling growth showed a positive correlation between the duration of gibberellin dipping and growth characteristics such as leaf number and SPAD value. Plant height, petiole length, leaf length and width, and leaf area varied significantly based on the interaction between dipping time and concentration. Crown diameter exhibited differences depending on the dipping time, with cuttings producing superior seedlings having a diameter of 8.0 mm or more for all treatments except the 30-minute, 100 mg·L^-1 treatment. The T/R ratio was significantly lower in the 30-minute, 50 mg·L^-1 treatment, indicating the highest plant vigor. Quantum yield was lower at a concentration of 150 mg·L^-1, showing a decreasing trend with increasing gibberellin concentration. Nonphotochemical quenching was significantly smaller in the 30-minute, 150 mg·L^-1 treatment, indicating an effective reduction of stress in the cuttings. Antioxidant content was highest in the 30-minute, 50 mg·L^-1 treatment and the 60-minute, 150 mg·L^-1 treatment. Moreover, the results of post-transplanting growth assessment showed no negative effect of gibberellin on flowering induction. Therefore, it was confirmed that gibberellin treatment during the cutting propagation of 'Seolhyang' strawberries had a positive effect on the production of high-quality seedlings. Dipping the cuttings in 50 mg·L^-1 gibberellin for 30 minutes is considered to be the most suitable method for improving growth and quality compared to the control.

This study aimed to examine the delivery conditions and microbial contamination of fresh-cut and ready-to-eat foods purchased from online markets between February and November 2023. Upon arrival, the average surface temperature of the products was 11.3℃. In the fresh-cut foods, the average number of total aerobic bacteria and coliforms was 4.5 log colony-forming units (CFU)/g and 1.2 log CFU/g, respectively, whereas in the ready-to-eat foods, these values were 10.6 log CFU/g and 1.2 log CFU/g, respectively. Pathogens, such as Staphylococcus aureus, Salmonella spp., Clostridium perfringens, Listeria monocytogenes, and pathogenic Escherichia coli were absent from all samples. Bacillus cereus was found in 2.7% of the fresh-cut foods and 0.9% of the ready-to-eat foods, with contamination levels averaging 0.05 log CFU/g and 0.01 log CFU/g, respectively. In the four samples in which B. cereus was detected, genetic testing of the six toxin genes produced by B. cereus revealed the presence of at least one enterotoxin gene, excluding the emetic toxin. L. monocytogenes was absent from ready-to-eat foods but was detected in 0.9% of fresh-cut foods. Analysis of the isolated L. monocytogenes confirmed the presence of six pathogenicity-related genes, including iap, indicating the potential risk of foodborne diseases.

This study investigated the ecological characteristics of Fraxinus chiisanensis Nakai, one of the endemic and rare plant species in Korea, based on its distribution status, characteristics of the growth environment, and species composition. A vegetation survey that analyzed the correlation between species distribution patterns and environmental variables, along with the traits of the emergent plant species, was performed according to the explanation of environmental growth conditions and phytosociological method for the location where F. chiisanensis is found. A total of 19 dominant locations and 9 non-dominant locations of F. chiisanensis were observed in 28 study sites in 12 regions, and a total of 155 taxa were observed. According to the vegetation climate of Korea, the growth environment of the study site where F. chiisanensis is located is characterized as cold and is primarily situated within the northern temperate deciduous broadleaf forest zone. The average elevation was 859m above sea level, with an average rock exposure of 60.4%, soil exposure of 24.7%, and an average slope of 18.7°. The taxa belonging to the top P-NCD(Percentage of Net Contribution Degree) among the emergent species were mostly designated as the taxa emerging in valley vegetation. The correlation analysis of environmental variables revealed that altitude had the strongest correlation, with rock exposure showing the second highest correlation. The ongoing dynamics of the F. chiisanensis forest are anticipated to persist due to the high P-NCD values exhibited by the F. chiisanensis within the shrub and herbaceous layers among the taxa associated with tree species. Most F. chiisanensis habitats are currently situated within protected regions such as national parks, provincial parks, and county parks, where there are relatively minimal human-induced disturbances. However, there is potential for damage in areas not designated as protected, such as forest tending operation sites or new hiking trails. Concerns about declining habitat quality have prompted suggestions for management strategies such as establishing Forest Genetic Resource Reserves in these locations. In addition, follow-up and further research should be conducted to identify possible sites for distribution and establish candidate conservation areas based on various environmental conditions of F. chiisanensis.

Our leaders and our nation exerted lots of efforts and sacrifices to make rapid change and development of our country in modern times. However, recently their negative images were gradually exposed to us, making our nation have their aspiration for well-conditioned leaders, along with their own responsibilities. For this study, who are good leaders and what are needed for them were deeply thought of. Although there was no clear solution, this study made a premise that the leaders should be nourished to have benevolence, knowledge, bravery and deed, realizing political activities to give our nation satisfactory results. For this, the leaders, for themselves, should make philosophical thoughts for becoming good leaders and for executing their thoughts. However, they are confronted with many problems to do so in real world. Therefore, it is necessary to consistently give them an country-level education for philosophy of leadership for them to form their own philosophical thoughts and to realize their thoughts in our actual lives. One type of method for that can be accomplished through contents of 《Seonghakjipyo》, written by Yulgok Yi yi (李珥, 1536~1584), for the hope of saint king. In this book, he described in details the sayings of the saints and his own thoughts on what should be learnt and practiced for doing self-discipline and ruling the country, adding that it was useful and common to all as well as the leaders. It can be said that this book is very usefulto educate philosophy of leadership for modern leaders, for it is containing the contents both for individuals to learn and practice for restoration of their human nature and for leaders to directly utilize in real political world. This argument may be originated from the fact that the wisdom and the deed needed for good leaders are, in general, all the same, although the system of the great organization like country has been changed. Based on the sections of Self-discipline and Politics in the above book, this study argued the general education for philosophy of leadership. It is focused on definition of education for philosophy of leadership, its meaning in 《Seonghakjipyo》, the reason for using the above book for it, and the suggestion of concrete methods to solve insufficiency of education programs at present for leaders and to execute education for philosophy of leadership that can be practicable in real world. This study showed that the above book could be used for education for philosophy of leadership, arguing that such education could be useful for independently solving many problems both the leaders and our nation might be confronted with in our lives.

The human leukocyte antigen (HLA) system, which is part of the major histocompatibility complex (MHC) plays a vital role in immune responses by differentiating between itself and foreign cells and antigens. The significant diversity of alleles affects disease susceptibility and immune responses within different populations. Specifically, the HLA-A and HLA-DRB1 alleles are associated with various immune-related diseases, and understanding the frequency and haplotype associations of these alleles is vital for genetic and immunological research. To investigate the distribution of these characteristics in Koreans, we isolated peripheral blood mononuclear cells (PBMCs) from blood samples donated by volunteers at the Seoul Central Blood Bank and performed HLA typing on 790 samples. Our study found that the HLA-A and HLA-DRB1 alleles are widely distributed within the Korean population, with HLA-A^*24:02 (21.7%) and HLA-DRB1*09:01 (9.9%) being the most frequent. Significant haplotype associations between specific HLA-A and HLA-DRB1 alleles were identified using the Chi-square test, suggesting that certain genetic combinations may influence disease onset. This insight could contribute to the development of predictive and preventative strategies for various diseases. The unique genetic characteristics of the Korean population highlight the importance of studying the HLA allele and the haplotype distributions in this group as key indicators for understanding disease susceptibility.

Korea has developed as an influential country over Asia and all over the world based on remarkable economic development. And the background of this development was possible due to the existence of those who sacrificed precious lives and contributed to the nation's existence in the past crisis. Every year, Korea holds an annual commemorative event with people of national merit, Korean War veterans, and their families, expressing gratitude for sacrifices and contributions at home and abroad, and providing economic support. The tragedy of the Korean War and the pro-democracy movement in Korea over the past half century will one day become a history of the distant past over time. As generations change and the purpose and method of exchange by region change, the tragic situation that occurred earlier and the way people sacrificed for the country are expected to be different from before. In particular, it is true that the number of Korean War veterans and their families is gradually decreasing as they are now old. In addition, due to the outbreak of global infectious diseases such as COVID-19, it is difficult to plan and conduct face to face events as well as before. Currently, Korea's digital technology is introducing various methods. 5G communication networks, smart-phones, tablet PCs, and smart devices that can experience virtual reality are already used in our real lives. Business meetings are held in a metaverse environment, and concerts by famous singers are held in an online environment. Artificial intelligence technology has also been introduced in the field of human resource recruitment and customer response services, improving the work efficiency of companies. And it seems that this technology can be used in the field of veterans. In particular, there is a metaverse technology that can vividly show the situation during the Korean War, and a way to digitalize the voices and facial expressions of currently surviving veterans to convey their memories and lessons to future generations in the long run. If this digital technology method is realized on an online platform to hold a veterans' celebration event, veterans and their families on the other side of the world will be able to participate in the event more conveniently.

Kinesin superfamily protein 5A (KIF5A) is the motor protein of kinesin-1 and forms a heterotetrameric complex by binding to KIF5B or KIF5C and kinesin light chains (KLCs), a non-motor protein. Amyotrophic lateral sclerosis (ALS)-associated KIF5A single nucleotide variants are clustered in the near exon 27 and are predicted to have a change in the carboxy (C)-terminal region of KIF5A. In patients with ALS, mitochondria membrane protein prohibitin 1 (Phb1) and Phb2 were found downregulated in the spinal cord. In this study, we confirmed that Phb2 binds to KIF5A. Phb2 bounds to the C-terminal region of KIF5A, which is the KIF5A-specific terminus, and KIF5A bounds to the C-terminal region of Phb2 but not to Phb1 in a two-hybrid assay. In human embryonic kidney-293T cells co-expressing EGFP-Phb2 and myc-KIF5A plasmids, Phb2 was co-immunoprecipitated with the motor proteins of kinesin-1, KIF5A and KIF5B, and the non-motor protein KLC1. In addition, both EGFP-Phb2 and myc-KIF5A were expressed at the same location in the cell. These results suggest that the binding of KIF5A to phb2 plays a role in mediating the association of kinesin-1 with mitochondria.
