These experiments were carried out to develop new techniques identifying XX-bearing embryos prior to implantation by immunological method. Antiserum to histocompatibility-Y(H-Y) antigen was prepared in adult SD(sprague-dawley) female rat by repeated immunization of newbone testis supernatant from males of the same strain. ELISA test was used to identify the H-Y antibody of antiserum. Total 124 mouse embryos (8-cell stage) were treated with H-Y antiserum and complement in BSA free Ho, pp. and Pitt's medium and cultured under the gas phase of 5% CO2 in air at 37$^{\circ}C$ for 24 to 48 hrs. The morphological characteristics of embryos treated were observed under the phase-contrast micro scope. The results obtained in these experiments were summarized as follows: 1. Optimal Density of H-Y antibody were a, pp.ared to be 0.27-0.47 by ELISA test. 2. Of total 124 embryos treated with H-Y antiserum and complement 69(55.6%) embryos developed to blastocyst and 55(44.4%) destroyed or arrested.

Objectives: This study surveyed the application of Comprehensive Dental Hygiene Care (CDHC), based on non-surgical periodontal therapy within the educational curricula of Korean universities and examined whether they recognized the need for CDHC. Methods: This study analyzed data from professors of dental hygiene practicum related subjects in 75 Korean universities. The collected data were analyzed using a Chi-square test, a Mann-Whitney U-test, and a Kruskal Wallis test via SPSS (Ver. 21.0). Results: First, the application scope of CDHC was higher in four-year universities than three-year ones with the scope of several characteristics increasing along with enrollment quota. The application scope of dental hygiene plans and actions increased with the number of patient practices in terms of periodontal evaluations. Second, the needs of the dental hygiene courses were more than 4 points in all characteristics. Although four-year universities exhibited higher points than three-year ones, there was no significant difference found except other test. Finally, all universities based their dental hygiene courses on case histories, oral and maxillofacial information, hard tissue modules, periodontal issues, and other tests, with needs also being high. Meanwhile, the application scope of the dental hygiene course evaluations was lowest in all characteristics. Conclusions: There were no significant differences in dental hygiene curricula among the universities. However, highly qualified and standardized educational courses and lectures should be developed by the Korean evaluation center for dental hygiene curricula using various studies as the basis of theory and practical classes, the total number of terms, number of case studies used, number of students per class, ratio of students to professor, and so on.

The aim of this study is to identify future-oriented tasks for Korean dental hygienists based on a literature review. A literature search is performed using 14 keywords related to tasks carried out by dental hygienists, and included articles published from 2000 to 2019 in the databases KISS, RISS, DBpia, NDSL, Papersearch, Pubmed, and Google Scholar. Six reviewers assessed the titles and abstracts of articles, and an article was selected if the study was considered to cover future-oriented tasks for Korean dental hygienists. Based on the results six local studies and two foreign studies were used for literature review and data extraction. In total, 38 tasks were classified as future-oriented tasks of dental hygienists according to the following criteria: 1) tasks that were specifically referred to as future-oriented tasks, and 2) tasks that could be classified as future-oriented tasks although no specific reference was made. Of these, the most frequently mentioned tasks were measuring periodontal pocket depth, dental hygiene assessment, providing dietary advice, infiltration anesthesia, and root planing. These were extracted from five of the eight studies, including both local and foreign studies. Dental hygiene planning, emergency, emergency management, and smoking cessation were the next most common tasks based on four studies. Even though some of these future-oriented tasks for Korean dental hygienists are included in the dentistry curriculum, and are currently performed as clinical practice for dental hygienists. Nonetheless, the reference to the legal scope is unclear. It is necessary to reconsider the scope of tasks of dental hygienists to reflect changes in domestic and foreign dental care delivery, thereby contributing to the oral health promotion of the public, where safety is guaranteed under legal protection.

As medical insurance had been implemented for Magnetic Resonance Imaging (MRI) from January 1, 2005, this study investigated whether there had been any change in the amount of the medical care utilization of patients who undertook MRI before and after the insurance coverage, and was to examine factors affecting the amount of medical care utilization of MRI. Data were collected from patients who undertook MRI before and after the insurance coverage for a year at a general hospital in Kyeanggi-do. $X^2$ and t-test were used for the analysis of their general characteristics, the number of MRI, and its medical costs before and after the insurance coverage, and hierarchical multiple regression analysis for the factors affecting the amount of the medical care utilization of MRI. The results of this study were as follows. First, the number of MRI after the insurance coverage was significantly decreased. Second, there was no significant difference in the total medical costs of MRI after the insurance coverage, but a significant difference was found in patient's share of medical costs. Third, six variables were found to be affecting the amount of the medical care utilization of MRI, and the variables showed to lead the number of MRI decrease after the insurance coverage. These six factors explained 21.4% of the total number of MRI. As MRI had been covered by insurance, the use of MRI and patient's share of the costs were deceased, but the total medical costs were not affected. Reasons for that could be found in that MRI insurance, different from the case of CT insurance coverage, was allowed not to cover some items and the kinds of diseases subjected to the insurance coverage were extremely limited, lowering insurance prescription rate. In addition to that, the average medical cost of MRI was not changed after the insurance coverage. Therefore, as future measures for the MRI insurance, coverage, it should be considered to allow insurance coverage to no coverage items and to expand the scope of benefit coverage, or to lower patient's share of the costs. Furthermore, researches should be done to explore how recipients will act and how suppliers will react if the coverage is expanded, including expanding the scope of coverage and reducing patient's share of the costs, as well as to conduct research on its economic analysis according to case mix.

This study is conducted to estimate economic ripple effects of subsidiary services of hospitals. Using the Input/Output Analysis, this study analyzes production inducement effect, added value inducement effect, and labor inducement effect. Also, it assesses potential economic effects of the subsidiary services of which the scope is expanded as the government's proposed in 2014. Data regarding hospital subsidiary services and economic effects are obtained from the hospitals' financial statements on the National Tax Services and the Bank of Korea. The major results of this study are summarized as follows; subsidiary service profits of hospitals are 466 billion won and rent profits of hospitals are 152 billion won. Of these, the rate of subsidiary service profits in tertiary hospitals is about 66% of total subsidiary service profits. Producement inducement effect of subsidiary services of hospitals is higher than that of total industry, service industry and medical service industry. Added value inducement effect of subsidiary services of hospitals is higher than that of total industry, manufacturing industry, service industry and medical service industry. Job position inducement effect of subsidiary service in hospitals is higher than that of total industry, service industry and medical service industry. Also, employment inducement effect of subsidiary service in hospitals is higher than that of total industry and medical service industry. The results may suggest that subsidiary services revenue in medical institutions contribute to improving operating profits. Facing with intense market competition and pressures to control health care costs, hospitals may need to determine whether subsidiary services help boost their profitability and improve customer satisfaction.

Nutrient (i.e., nitrogen and phosphorus) budgets are required under a 'Livestock Excreta Survey'. A nutrient budget is one of the agri-environmental indicators that calculates the difference between the inputs and outputs of the amount of nutrients within a certain boundary and for a certain time period (e.g., 1 year). In this study, a nutrients budget model was developed to effectively determine the surplus of nutrients within a region in Korea. The C# program language was used in order to facilitate the deployment of a graphical user interface (GUI) and to enhance compatibility. Also, the model was developed on Windows OS, which is the commonly used operating system in Korea. The model was based on the OECD/Eurostat nutrient budget method, and it was modified to consider manure composting procedures as well. There are key features of the nutrient budget model, including directly use of the original data sets from various input and output sources, and a collectively exchange of the address in different formats. The model can quickly show the results of various spatial and temporal resolutions with the same data, as well as perform a sensitivity analysis with coefficients and easily compareresults using tables and graphs. Further, it would be necessary to study the extension of the scope of utilization, such as the application of various nutrient budget methods. It would also be helpful to investigate both pre and postprocessing information such as linking input data through online systems.
