Oral history is the work to make the record of the verbal content recreated by the memories of the survivors. Oral history recording is accomplished through the collaboration of the interviewee, the interviewer, the cameraman, the recorder, the transcriber and etc. Therefore, it is important for the context at the time of the production to be expressed. So planning for the collection of oral records, the collection of oral records, and their preservation and maintenance should be managed systematically. This study, being started from this sense of problem, designed conceptual model of metadata to well reflect the contextual characteristics of the oral records of the women life of among the oral records and extracted the elements through this. The whole process of records management including from planning, production, preservation, management, and leading to use, related to the oral records of the women life, was classified into a hierarchy. It also proposed the system which can express the characteristics of the 'gender' through authority records and subject thesaurus.

Microservice architecture focuses on dividing it into small and lightweight services to build for the purpose of performing very close business functions. So it tends to concentrate only on agility, productivity, reliability, and ease of deployment of software development. Microservice architecture considers database as just a file or storage for storing and extracting data, emphasizing that data quality can be sacrificed for convenience and scalability of software development. Database reverse engineering for understanding database structure and data semantics is needed for data utilization for business decision making. However, it is difficult that reverse database engineering is applied in microservice architecture that neglects data quality. This study proposes database reverse engineering method that utilizes master data to restore the conceptual data model as a solution. The proposed method is applied to the return service database implemented by microservice architecture and verified its applicability.

Newly, the fourth industrial revolution is a way of describing the blurring of boundaries between the physical, digital, and biological worlds. It's a fusion of advances in AI (artificial intelligence), robotics, the IoT (Internet of Things), 3d printing, genetic engineering, quantum computing, and other technologies. At the world economic forum in Davos, switzerland, in january 2016, chairman professor klaus schwab proposed the fourth industrial revolution for the first time. In order to apply the AHP (analytic hierarchy process) analysis method, the first stage factors were designed as Natural, Water, Earth and Atom energy. In addition, the second stage factors were organized into 9 detailed energies presented in the conceptual model. Thus, we present the theoretical and practical implications of these results.

This is an implementation study towards the development of a strategy to improve the pneumonia adequacy evaluation index of regional public hospital and to confirm its effectiveness. One physician, eight nurses, one computer room staff, and one nursing professor working at a regional base public hospital located in N city participated in this study from March to October 2021. An implementation study was conducted based on the conceptual model of Zuber-Skerritt & Fletcher. The stages of planning, implementation, evaluation, and reflection were operated in two cycles, and the effectiveness was evaluated in the second and third quarters. Compared to the pneumonia adequacy evaluation index in 2019, all indicators reached 100% of the standard target in 2021. The results of this study therefore infer that to provide higher quality medical services in the future, it is necessary to apply medical quality improvement activities through practical research under multidisciplinary participation and cooperation and to review the applicability of clinical sites.

The purpose of this paper is to determine the extent to which job satisfaction affects organization commitment and organization performance among industrial security personnel. To this end, we attempted to conduct a four-week survey from August 28 to September 22, 2023, targeting about 150 workers working as industrial security guards in the field. According to the survey, the variables were comprised of "first, job satisfaction, second, organization commitment and third, organization performance" and based on this, three research hypotheses were proposed. After confirming that the internal consistency of each measurement item was satisfied, discriminant validity and conceptual reliability were calculated, and the discriminant validity of each variable was verified. As a result of the analysis, after conducting regression analysis to verify the research model, the results show that among the three research hypotheses, "Job Satisfaction ⇨ Organization Commitment, Job Satisfaction ⇨ Organization Performance" was found to be statistically significant and was adopted. We calculated that "Organization Commitment ⇨ Organization Performance" was not significant and was rejected.

Large language models (LLMs) have revolutionized the global landscape of technology beyond the field of natural language processing. Owing to their extensive pre-training using vast datasets, contemporary LLMs can handle tasks ranging from general functionalities to domain-specific areas, such as radiology, without the need for additional fine-tuning. Importantly, LLMs are on a trajectory of rapid evolution, addressing challenges such as hallucination, bias in training data, high training costs, performance drift, and privacy issues, along with the inclusion of multimodal inputs. The concept of small, on-premise open source LLMs has garnered growing interest, as fine-tuning to medical domain knowledge, addressing efficiency and privacy issues, and managing performance drift can be effectively and simultaneously achieved. This review provides conceptual knowledge, actionable guidance, and an overview of the current technological landscape and future directions in LLMs for radiologists.

Risk assessment was carried out in order to improve the remediation and management strategy on a contaminated gunnery site, where a flood control reservoir is under construction nearby. Six chemicals, including explosive chemicals and heavy metals, which were suspected to possess risk to humans by leaching events from the site were the target pollutants for the assessment. A site-specific conceptual site model was constructed based on effective, reasonable exposure pathways to avoid any overestimation of the risk. Also, conservative default values were adapted to prevent underestimation of the risk when site-specific values were not available. The risks of the six contaminants were calculated by API's Decision Support System for Exposure and Risk Assessment with several assumptions. In the crater-formed-area(Ac), the non-carcinogenic risks(i.e., HI values) of TNT(Tri-Nitro-Toluene) and Cd were slightly larger than 1, and for RDX(Royal Demolition Explosives), over 50. The total non-carcinogenic risk of the whole gunnery range calculated to a significantly high value of 62.5. Carcinogenicity of Cd was estimated to be about $10^{-3}$, while that of Pb was about $5\;{\times}\;10^{-4}$, which greatly exceeded the generally acceptable carcinogenic risk level of $10^{-4}{\sim}10^{-6}$. The risk assessment results suggest that an immediate remediation practice for both carcinogens and non-carcinogens are required before the reservoir construction. However, for more accurate risk assessment, more specific estimations on condition shifts due to the construction of the reservoir are required, and more over, the effects of the pollutants to the ecosystem is also necessary to be evaluated.

Objectives: The purpose of this study is to provide a basic structure for the establishment of the direction of school health programs, an overview of the historical changes of school health programs and their results, and a conceptual framework on school health programs. Methods: The data analysis has been done using a statistical almanac, relevant laws and regulations, operation handbook of the program, theses, reports, records of public hearings, and other reports as a technical research primarily based on evidence. The methodology of this research classifies the development and growth transition of school health programs during a historical period through the investigation of regulations, organization, manpower, and its program via its development process and to provide a basic tool to design a solid school health policy. Results: A The growth and development of school health programs The development of school health programs was classified into three different periods including the forthcoming period (1945~1967), the completion period (1967~1993), and the actualization period based on the establishment of legislation for School Health Law, other relevant legislation, and the contents of school health programs (1993~present). B. Policy direction of school health programs School health programs have reestablished their goals and range based on basic direction, and developed the W1it model of information structure for school health program management and its basic structure. Finally, the stepwise support system through the building of the school health support center is recommended. (1) The basic direction of school health programs has proposed 7 basic goals to reestablish the policy direction of health improvement based on total health. (2) The W1it model of information system and the school health information system for school health program management has been developed to utilize positive management. (3) School health policy through the study of the health laws and systems has been developed. The necessity of school health support center for the policy support, functional support and operation support has also been proposed. Conclusions: It is necessary to build a school health support center that consists of health professionals in charge of policy support, functional support, and program support of school health programs in order to realize and develop new policy.

This study comparatively examines a causal model of employee attatchment which focuses on employee's organizational commitment and intent to stay with an organization. This study is based on two separate studies of employee attachment among teachers : the U.S. case of the Chicago Public Schools (CPS) and the South Korean case of the Seoul Educational District (SED). The main purpose of this study is to replicate in Korea the CPS study. A revised model based on the unique characteristics of Korean teachers is also developed and estimated. The Price Mueller model of employee attachment provides the basic theoretical framework for this study. It includes five general classes of variables : 1) employee responses to work variables : job satisfaction, commitment, and intent to stay; 2) psychological stress variables: role ambiguity, role conflict, work overload, and quality of students; 3) social structural variables: autonomy, routinization, distributive justice, and legitimacy; 4) economic structural variables: pay, job security, promotional opportunities, and job opportunities; and 5) work orientation variables : career commitment, normative commitment, work motivation, affectivity, work values, and met expectations. The data was collected through questionnaire survey and a sample of 649 secondary school teachers in Seoul, South Korea, was included in the final analysis. Covariance structure analysis (LISREL) was used to estimate the causal model. The results indicate that the endogenous variables of job satisfaction and commitment play a considerably less important role than in the U.S. model in mediating the effects of the exogenous variables on intent to stay, and the model fails to explain the majority of the variance in intent to stay. In addition, the new variables added to the revised Korean model do not bave significant effects on intent to stay. The structural characteristics of the employment relationship and labor markets associated with Korean teachers forced mobility and closed external markets - are largely accountable for the major differences between the Korean and the U.S. cases. The study suggests that conceptual and empirical work on what produces employee attachment under these structural constraints needs to receive more attention in future studies.
