The purpose of this study is to design textbook metadata as a basic task for building a textbook database. To this end, reading textbooks were defined as a category of textbooks, and a metadata development methodology was established through previous research. In order to ensure that bibliographically essential elements are not omitted, the catalog description elements of institutions that collect, accumulate, and service textbooks such as the National Library of Korea were investigated. The elements of Dublin Core, MODS, and KEM were mapped to derive elements suitable for describing textbooks. Finally, a set of textbook metadata elements consisting of 14 elements in three categories - bibliography, context, and textbook characteristics were presented by adding publication type, genre, and curriculum period elements. The 14 elements are titles, authors, publications, formats, identification sign, languages, locations, subject names, annotation, genres, table of contents, subjects, curriculum period, and curriculum information. In this study, we contributed to this field by discussing how to organize textbook resources with national knowledge resources, and in future studies, we proposed to evaluate usability by applying metadata elements to actual textbooks and revise and supplement them according to the evaluation results.

The purpose of this study was to prepare basic data for improving school library information service by investigating the information usage behavior of specialized high school students. Preferred information sources for each situation requiring information and the level of solving information problems using information sources were investigated, and difference analysis was conducted by department and grade. As a result of the survey, the percentage of students who preferred Internet portal services, personal information sources (teachers, friends, parents), and social media was high, while the percentage of students who preferred traditional print information sources and mass media was very low. The average score of the information problem solving level was 3.55, and the problem solving level in the areas of employment and career/admission was relatively low. Preferred sources of information were similar regardless of grade and department, and the difference between departments in information problem solving level was not statistically significant, but the difference between grades was statistically significant. In addition, there is an academic contribution in this field that specific examples of youth information use behavior have been added. Based on the results of the study, librarians should make efforts to verify the reliability of Internet portal site information, improve and promote library information sources, and expand library use education. In future studies, it was suggested to develop customized information services.

This paper attempts to examine the economic impact of technological barrier to trade(TBT) between Korea and China by using international input-output approach. With the tariff/quota reduced or eliminated since WTO's launch, the interest in TBT as a non-tariff barrier has been increased, and then there have so far been a large number of empirical studies on quantifying its effect in foreign. But still this area of study in Korea is limited in the literature survey. In encouraged in this situation, focusing on bilateral trade between Korea and China, which has been significantly increased in recent years, we have tried to estimates the impact of TBT on their output and employment. We use Asian International Input-Output Table(AIIO) for the year 2000 published by IDE-JETRO, and also use the estimated sectoral TBT provided by Ha et al.(2010). According to the result, there will be generated $3.63 billions values in outputs, and 18.1 millions persons in employments at most. And also we found that there is weak interdependence in sectoral and spatial linkage between two countries.

The sewage system was continuously distributed as a concept of public service and protection for water system such as wet-land, resulting in deterioration of the management of sewage management institutions. Accordingly, under the leadership of the central government, various sewage policies are being promoted to streamline the management of sewage management institutions. The main points were related to costs, and typical characteristics include wastewater cost and wastewater discharger cost. In this research, the current status and characteristics of the wastewater discharger cost of 71 local governments in Korea were analyzed. As a result, 41 places (57%) were found to be less than 1,000,000 won/m³ to 2,000,000 won/m³, with an average was 1,990,653 won/m³ (median was 1,918,000 won/m³). In addition, the rate of wastewater discharger cost was increased when the wastewater discharger cost was higher stage. The influential parameters of local governments, which were relatively correlated with the wastewater discharger cost, were analyzed as the rate of recovering wastewater cost and financial independence rate. The results of this research could be used as basic data for wastewater discharger cost, and future researches are needed on how to calculate the appropriate level of wastewater discharger cost.

This study used optical and scanning electron microscopy to analyze the surface oxidation phenomenon that accompanies a γ'-precipitate free zone in a directional solidified CM247LC high temperature creep specimen. Surface oxidation occurs on nickel-based superalloy gas turbine blades due to high temperature during use. Among the superalloy components, Al and Cr are greatly affected by diffusion and movement, and Al is a major component of the surface oxidation products. This out-diffusion of Al was accompanied by γ' (Ni₃Al) deficiency in the matrix, and formed a γ'-precipitate free zone at the boundary of the surface oxide layer. Among the components of CM247LC, Cr and Al related to surface oxidation consist of 8 % and 5.6 %, respectively. When Al, the main component of the γ' precipitation phase, diffused out to the surface, a high content of Cr was observed in these PFZs. This is because the PFZ is made of a high Cr γ phase. Surface oxidation of DS CM247LC was observed in high temperature creep specimens, and γ'-rafting occurred due to stress applied to the creep specimens. However, the stress states applied to the grip and gauge length of the creep specimen were different, and accordingly, different γ'-rafting patterns were observed. Such surface oxidation and PFZ and γ'-rafting are shown to affect CM247LC creep lifetime. Mapping the microstructure and composition of major components such as Al and Cr and their role in surface oxidation, revealed in this study, will be utilized in the development of alloys to improve creep life.

Objectives This study aimed to investigate domestic clinical research trends in Shinbaro pharmacopuncture, identify diseases managed using Shinbaro pharmacopuncture, and suggest the direction for future studies to increase its clinical utilization. Methods This study used five steps proposed by Arksey and O'Malley and the PRISMA-extension for scoping reviews checklist. We examined published literature on Shinbaro pharmacopuncture studies reported until June 5, 2023, in the following eight databases (Research Information Sharing Service, Science ON, Oriental Medicine Advanced Searching Integrated System, KMBASE, The Society of Internal Korean Medicine, PubMed, EMBASE, and the Cochrane Library). The search terms used were 'Shinbaro' or 'Sinbaro'. Results A total of 47 studies were included in our analysis. Of these, 37 (78.7%) were interference time series studies. Shinbaro pharmacopuncture was the most frequently used treatment for lumbosacral disease (n=15). In the facial area, ST4 and ST6 were used in five out of six studies, and in the shoulder area, TE14 and LI15 were used in all studies. Nine of the 15 studies in the lumbosacral area used the EX-B2. The other parts mostly used the pressure points. Compared to other pharmacopuncture methods, the treatment effect was similar to that of bee venom, and faster than that of jungsongouhyul. Conclusions This is the first scoping review of Shinbaro pharmacopuncture therapy in South Korea. Studies with a high level of evidence based on sole treatment, large capacities, and standardization of Shinbaro pharmacopuncture need to be conducted to increase its clinical utilization.

Background: This study aimed to assess the appropriate allocation of emergency medical beds across 17 provinces and presume the economic benefits associated with such allocation. Methods: To estimate the optimal allocation of emergency medical beds by province, data from the Statistics Korea's "cause of death statistics (2014-2021)," regional statistics on "area, population, gender, age," and "population projections" were utilized. The "number of emergency beds by city and district" provided by the Health Insurance Review and Assessment Service was also used. In estimating the economic benefits of preventing avoidable emergency deaths due to the expansion of emergency medical facilities, guidelines from the Korea Development Institute and the Korea Transport Institute were referenced to calculate the wage loss costs associated with emergency deaths and estimate the economic benefits. Results: The optimal ratio of emergency medical beds allocation by region was highest in Gyeonggi, Seoul, Gyeongnam, Gyeongbuk, and Busan, while Daejeon, Jeju, and Sejong showed lower ratios. Additionally, the prevention of avoidable deaths and economic benefits resulting from the increase in emergency medical facilities were highest in Gyeonggi, Seoul, Gyeongbuk, Gyeongnam, and Busan. However, when standardized by population, the prevention of avoidable deaths and economic benefits were analyzed to be highest in Gyeongbuk, Chungnam, Jeonnam, Gyeongnam, and Busan. Conclusion: The results of this study can serve as foundational data for future policy measures aimed at addressing the imbalance in the supply of emergency medical facilities across regions. Considering regional characteristics in the distribution of emergency medical facilities is expected to ultimately increase the efficiency of national finances and yield economic benefits.

This study analyzes the sculptural art of SeokhaSichan(石霞施讚, 1893-1958), a significant figure in modern Korean Buddhist art, to re-examine his contributions and standing in the history of Korean Buddhist art. Sichan expanded the boundaries of modern Korean Buddhist art by developing a unique style based on the traditional sculptural techniques he learned from his mentor, Wanho Nakhyeon (玩虎洛現, 1869~1933). This study explores Sichan's artistic development, focusing on his artistic characteristics and sculptural evolution. Sichan's early works are characterized by small sculptures modeled after the main Buddha of Seokguram Grotto and heavily influenced by his mentor, WanhoNakhyeon. In his later works, notable features include a sense of massive volume, larger scale, upright postures, integration of the Buddha statue with its pedestal, and decorative treatment of drapery. These changes are interpreted as Sichan's response to social changes and his reflection of inner contemplation and artistic exploration in his works. This study reveals the influences of Wanho Nakhyeon, collaborations with Toewon Woneil(退雲圓日, 1877~1939), interactions with patron Kim Jiseonghwa(金至誠華), and master-disciple relationship with successor Geumchun Seongpil(金春性必) through literature review and newly discovered works by Sichan. His works and his artistic evolution are pivotal milestones in the history of modern Korean Buddhist sculpture, demonstrating a unique integration of traditional and modern aesthetics. This study provides valuable insights into how Sichan's artistic legacy was inherited and developed by subsequent generations and offers crucial materials for the study of modern Korean Buddhist sculpture history.
