This study focused on whether employees' perceived leader's creativity has a significant effect on employees' job satisfaction and innovative behavior. In addition, this study analyzed the mediating effect of positive psychological capital and creative self-efficacy in the relationship between perceived leader creativity and employee satisfaction with the job or innovation behavior, and analyzed the moderated mediating effect of team cohesion. This study conducted confirmatory factor analysis and path analysis for each factor using the measurement tool verification method using the SmartPLS 3.0 structural equation model, and empirically analyzed the research model. As a result, it was found that the creativity of employees' perceived leaders did not directly significantly affect employees' job satisfaction and innovation behavior. However, it was found that positive psychological capital significantly mediated the relationship between perceived leader creativity and job satisfaction or innovative behavior. In addition, positive psychological capital and creative self-efficacy have a complete double-mediation relationship between the employees' perceived leader's creativity and employees' innovative behavior. However, positive psychological capital and creative self-efficacy don't have a double-mediation relationship between the employee's perceived leader's creativity and employees' job satisfaction. Finally, Team cohesion was found to moderate the relationship between perceived leader creativity, positive psychological capital (or creative self-efficacy). However, the research model that the moderated mediating effect of team cohesion on the relationship between leader's creativity, the mediating variables(positive psychological capital and creative self-efficacy), and job satisfaction (or innovative behavior) was significant only for groups with high team cohesiveness. This study examined the needs of the times for the importance of creativity of perceived leaders and analyzed the relationship between factors influencing job satisfaction and innovation behavior of organizational members. The study is meaningful in that it suggested a plan to establish a specific organizational strategy to enhance positive psychological capital and creative self-efficacy.

Background: Disabled people have particularly restricted access to health care. In response to this, the pilot project for the general physician (GP) system for disabled people was implemented in 2018, based on the rights of people with disability to the Health Act in South Korea. However, its participants were 0.2% among the total of those with severe disabilities in 2021. Therefore, this study examined the factors related to registering with a GP and the access level to its services to suggest implications for activating the participation of disabled people. Methods: We analyzed factors affecting the registration with a GP and the number of using the services among the participants of the GP system during May 2018 and December 2021 by conducting hierarchical logistic regression and hierarchical regression. The data were linked with the national health insurance data to examine various predictors, including disability types, socioeconomic status, health status, and GP registration. Results: As a result of analyzing the factors affecting whether or not to register for the pilot project, those with disabilities (physical disabilities, brain lesions, visual, intellectual, mental, and autistic disability) eligible for disability care (odds ratio [OR], 4.157) than other disability, and those living in metropolitan (OR, 4.330) or cities (OR, 3.332) than rural residences were highly likely to enroll the pilot study. Health-related variables also predicted the registration status of the pilot project. The predictors related to GP enrollment types (membership type: general health or disability care, GP's affiliation: clinics or hospitals) significantly influenced levels of access to services. Conclusion: It is necessary to develop the GP project for disabled people by considering the variation in types of disability, residences, and health. Further study will be needed to investigate the impact of GPs on the level of participation among disabled people.

An experiment was conducted to evaluate the biologically adverse effect of increased carbon dioxide in seawater on marine bacteria, Vibrio fischeri. We measured the bioluminescence and cell density at every 6 hours for 24 hours of the whole incubation period after exposing test microbes to a range of $CO_2$ concentration such as 380(Control), 1,000, 3,000, 10,000 and 30,000 ppm, respectively. Significant effect on relative luminescence(RLU) of V. fischeri was observed in treatments with $CO_2$ concentration higher than 3,000 ppm at t=12 h. However, the difference of RLU among treatments significantly decreased with the incubation time until t=24 h. Similar trend was observed for the variation of cell density, which was measured as optical density using spectrophotometer. The results showed that a significant relationship between $CO_2$ concentration and bioluminescence of test microbes was observed for the mean time. However, the inhibition of relative bioluminescence and also cell density could be recovered at the concentration levels higher than 3,000 ppm. The dissolved $CO_2$ can be absorbed directly by cell and it can decrease the intracellular pH. Our results implied that microbes might be adversely affected at the initial growing phase by increased $CO_2$. However, they could adapt by increasing ion transport including bicarbonate and then could make their pH back to normal level. Results of this study could be supported to understand the possible influence on marine bacteria by atmospheric increase of $CO_2$ in near future and also by released $CO_2$ during the marine $CO_2$ sequestration activity.

In this study, we delve into the potential for innovative cultural education techniques that utilize the timeless tales of Princess Bari and The Tale of Shim Cheong as tailored for the upcoming generations of overseas Korean learners. With a rising number of young overseas Koreans born and raised in their host countries, there emerges a pressing need to craft an educational framework that resonates with the evolving dynamics of their generation. Our endeavor revolves around proposing educational strategies that help solidify identity while carefully considering the intrinsic motivation prevalent among most overseas Koreans. Naturally, the choice of employing the classic epics Princess Bari and The Tale of Shim Cheong as educational resources was deliberate. These narratives are rich in rites of passage and offer profound insights into the transformative journey of their protagonists. Both characters are affluent women in patriarchal societies, and both embark on quests to redefine themselves through new relationships, liberating themselves from the confines of parental ties. This narrative framework provides a unique opportunity for overseas Koreans who are often adrift in the social fabric of their adopted countries. These stories inspire them to introspect and contemplate their own identities. By intertwining their personal narratives with the empowering stories of characters, students are provided a chance to reaffirm their authentic selves. Therein, a paradigm shift can occur that allows individuals to embrace the core elements that define them. Our ultimate objective was to enable students to explore their own stories and immerse themselves in the intricate narratives of classical works. This immersive experience fosters a profound sense of unity with the characters and paves the way for a comprehensive educational plan. This plan not only celebrates the hybrid nature of identity but also cultivates a deep sense of positivity within amalgamated 'subjects.' Such an approach not only fosters a stronger connection with one's heritage but also sparks a genuine curiosity about and affinity for the rich cultural tapestry of one's home country. It's not just education; it's a transformative journey that enriches the lives of overseas Koreans and nurtures a profound bond with their cultural roots.

Aggregate typically refers to sand and gravel formed by the transportation of rocks in rivers or artificially crushed, constituting a core resource in the construction industry. Gyeongsangbuk-do, the largest administrative area in South Korea, produces various sources of gravel, including forest, land (excluding other sources), river, and crushed stone. As of 2022, it has extracted approximately 6.96 million cubic meters of aggregate, with permitted production totaling around 4.07 million cubic meters and reported production of about 2.88 million cubic meters. The aggregate demand in Gyeongsangbuk-do is estimated to be 12.39 million cubic meters according to the estimation method in Ready-Mix Concrete. From the supply perspective, about 120 extraction sites are operational, with most municipalities maintaining an appropriate balance between aggregate demand and supply. However, in some areas, there is inbound and outbound transportation of aggregate to neighboring regions. Regions with significant inbound and outbound aggregate transportation in Gyeongsangbuk-do are areas connected to Daegu Metropolitan City and Pohang City along the Gyeongbu rail line, showing a high correlation with population distribution. Gyeongsangbuk-do faces challenges such as population decline, aging rural areas, and insufficient balanced regional development. Analysis using GIS reveals these trends in gravel demand and supply. Currently in this study, Gyeongsangbuk-do meets its demand for aggregate through the supply of various aggregate sources, maintaining stable aggregate procurement. River and terrestrial aggregates may be sustained as short-term supply strategies due to the difficulty of longterm development. Considering the reliance on raw material supply for selective crushing, it suggests the need for raw material management to maintain stability. Gyeongsangbuk-do highlights quarries in the forest as an important resource for sustainable aggregate supply, advocating for the development of large-scale aggregate quarries as a long-term alternative. These research findings are expected to provide valuable insights for formulating strategies for sustainable management and stable utilization of aggregate resources.

In the 7th and 8th centuries, Chinese Buddhism was at its peak, and major sects emerged and began to differ from one another in significant ways. This fact was also revealed through several versions of Biographies of the Eminent Monks and changes observable in the peculiarity of their formats. In the early 6th century, Huijiao (慧皎) compiled Gaosengzhuan (高僧傳, Biographies of Eminent Monks) which contains the history of Buddhism after it was introduced to China. At this time, he established a new format called the ten-subjects (十科). In 645, Daoxuan (道宣) used these ten-subjects as the basic framework to compile Xu-Gaosengzhuan (續高僧傳). However, by modifying and supplementing some parts of the ten-subjects, he standardized the ten-subjects into a format suitable for historiography. After the Xu-Gaosengzhuan, several versions of Biographies of the Eminent Monks were compiled in a format that further modified the ten-subjects. Fazang (法藏) wrote Huayanjing zhuanji (華嚴經傳記, 690?) which consisted of the ten-subjects, but the names and meanings of the subjects changed significantly to emphasize the Avatamsaka philosophy. Subsequently, while compiling Hongzan fahuazhuan (弘贊法華傳, 706?), Huixiang (惠詳) compiled a newly modified list of eight-subjects based on the ten-subjects of Gaosengzhuan and Xu-Gaosengzhuan. Sengxiang (僧詳) compiled Fahua xhuanji (法華傳記, 750?) in the format of twelve-subjects which added two new subjects to the ten-subjects of the Huayanjing zhuanji. These two formats focused on faith rather than philosophy. Even in the Chan (Zen) schools, a series of Biographies of the Eminent Monks was compiled from the beginning of the 8th century. Chuan fabaoji (傳法寶紀, 713?), Lengqui shiziji (楞伽師資記, 713?), Lidai fabaoji (歷代法寶記, 774), and Baolin zhuan (寶林傳, 801) are all examples of such compilations. However, the format of these four Biographies of the Eminent Monks was completely different from prior versions. Without setting any subjects, the authors established and described a dharma lineage transmitted continually from master to disciple. This is because Chan Buddhism does not rely on Buddhist texts but focuses on monks achieving realization through other means. At first, only the Chinese patriarchs were listed, but starting with Baolin zhuan, 27 patriarchs including Buddha and Kasyapa were included in the dharma lineage and presented as history. This fictional lineage was based on the need to secure sectarian superiority and legitimacy as Chan Buddhism flourished.

Jo Jeongsan's religious activity undertaken to benefit society can be organized into two categories. First, attention can be paid to Jo Jeongsan's religious activity of establishing religious order by enshrining Kang Jeungsan as the God of Ninth Heaven and making the Great Dao of Heaven and Earth the basic idea inspiring the social activity of his order. This was completed through the 50 years of propagation work carried out by Jo Joengsan in accordance with Kang Jeungsa's purpose of saving the world and its inhabitants. Second, his practice of social work in the field of people's lives based on the idea of the Dao can also be observed. This religious activity of Jo Jeongsan which began in 1909 was the sacred manifestation of his will to realize Kang Jeungsan's purpose of saving the world and people, and it was also a practice of spreading virtue throughout the world. In addition, Park Wudang carried out Sihak and Sibeop Gongbu (two varieties of holy work) for the cultivation of Dao trainees, and those methods came from the systematic cultivation practice established by Jo Jeongsan. Regarding this, we can refer to Kang Jeungsan's saying, "As the Dao shall dwell in the 12,000 peaks of Geumgang Mountain, the same number of sages who were enlightened to the Dao will be born into the world." The perfected state of human maturity or the emergence of people who are enlightened to the Dao would be the completion of the idea of saving the world and its inhabitants. Therefore, the holy works of Sihak and Sibeop that are now being carried out can be seen as the continuance of the pursuit of saving the world and humankind, as it was continually upheld by Park Wudang's predecessors, Jo Jeongsan and Kang Jeungsan.

The present study aims to investigate the design standard for acoustic criteria of Korean traditional music which could be used for the design of Korean traditional music halls. In order to do this, subjective listening tests were undertaken to musicians using auralized sounds which were convolved with the impulse response of traditional instruments recorded in an anechoic chamber. 94 pairs of sound were made which have different value of acoustic parameters including RT, BR, Brilliance, G, C80, ITDG, IACC. A paired comparison method(PCM) was used to analyze the results from the subjective listening tests. The results show that the preference of acoustic criteria for the Korean traditional music is far different from those of western music. As a result, specific range of acoustic criteria were suggested for the appropriate acoustic conditions of Korean traditional music. Also, a guideline of the acoustic design of halls for performing the Korean traditional music was suggested which could be used as a basic reference in the future works.

This study investigated the levels of 345 pesticide residues in 50 herbal medicines sold in Incheon metropolitan city to determine their safety. Pesticide residues are harmful substances that can cause serious health problems owing to their toxicity and carcinogenicity. The analysis of pesticide residues in the samples was conducted using the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method, known for its high analysis efficiency, to analyze a wide range of pesticides for which no standards have been set. The analysis was cross-validated with the pretreatment method outlined in the Korea Pharmacopoeia. Among the 50 samples encompassing 24 different herbs, 22 pesticide residues were detected in 24 samples, covering 7 distinct herbs, resulting in a detection rate of 48%. It is noteworthy that, except for two cases, all detected pesticides were those for which no standards were set. However, after conducting a risk evaluation considering the daily dosage of herb, it was determined that the levels of pesticide residues were within safe limits. Pesticides with high frequency within the same category of herbs were detected, indicating the necessity for continuous monitoring and regulation. In addition, comparative analysis using the pretreatment method outlined in the Korean Pharmacopoeia, yielded similar results, suggesting the possibility of analyzing pesticide residues in herbs using the QuEChERS method. The study emphasizes the importance of continuous monitoring of pesticide residues in herbs and the development of high-efficiency reliability analysis methods should continue to ensure consumer safety.

Established in 1909, the Imperial Museum was the forerunner of Korean museums, and its collection formed the foundation of today's National Museum of Korea. However, when the Imperial Museum was first established in Changgyeonggung Palace, a zoo and botanical garden were created in addition to the museum. From 1911 onward, these three facilities were collectively referred to as Changgyeongwon Park. The zoo and botanical garden remained at Changgyeongwon when the museum was relocated in 1938, as did some of the items from the collection of the Yi Royal Household Museum. Among them were palanquins used by the royal family and folk items such as armor, as well as taxidermized birds. These stuffed birds were displayed in the corridor of Myeongjeongjeon Hall in Changgyeongwon, and were also displayed in the specimen hall at the back of Myeongjeongjeon Hall. The stuffed birds in particular should prompt a reconsideration of the nature of the Imperial Museum (Yi Royal Household Museum). The museum had been known as a prominent art museum, mainly collecting masterpieces of ceramics (such as Goryeo celadon), Buddhist sculptures, and paintings. However, this character seems to have been just one aspect of the museum. Along with the zoo, which housed live animals, and the botanical garden, which included greenhouses for tropical plants, the museum also featured specimens like taxidermy, suggesting that its initial aim, from a museological perspective, was to be a more comprehensive museum. Notably, Shimogoriyama Seiichi, who managed the general affairs of the museum, collected and cataloged Korean avian specimens from 1908 to 1917. This suggests that the zoo and botanical garden were not merely for entertainment purposes, but also served a museological purpose. However, the Imperial Museum (Yi Royal Household Museum) lacked the essential research and educational functions necessary for a museum, beyond its collecting and exhibition roles. For instance, although specimens of stuffed Korean birds were collected, they were not thoroughly researched. This indicates that while the museum's collection was acquired from a museological perspective, it did not advance into more specialized research. This study aims to examine how the characteristics of the Yi Royal Household Museum have evolved by analyzing the inventory of the museum's collections and the list of Korean bird specimens it held.
