  • The setting of protective relays, which is critical to the power system security and reliability, requires a huge volume of data processing and repetitive calculation. Since it has been performed by relay engineers manually, it is vulnerable to human errors, its computerization has been pursued, in which the efficient management of the data is the key to the success. The database for power system protection must accommodate not only the power system network data but also a variety of protective devices. Also its information should be able to be viewed and updated with easy by operators and by computer programs. This paper describes several existing database designs for power system protection, their advantages and disadvantages. Also this paper has identified the required function and designed the database for the KEPCO power system data structure for the benefit of the relay setting process, etc..

  • Since its establishment in 2018, the Young Generation Network (YGN) has been dedicated, with support of the International Radiation Protection Association (IRPA), to a variety of activities to promote communication, collaboration and professional development of students and young professionals in the area of radiation protection and its allied fields. This article reports our recent activities from the middle of 2018 to the beginning of 2021, with highlights on some important events: "Joint JHPS-SRP-KARP Workshop of Young Generation Network" (December 2019 in Japan); contribution to "Nuclear Energy Agency Workshop on Optimization: Rethinking the Art of Reasonable" (January 2020 in Portugal); survey on the impact of coronavirus disease 2019 (COVID-19) on radiation protection among IRPA YGN members (March 2020); and contribution to IRPA15 (15th International Congress of the IRPA; January-February 2021, online). The discussion and insight obtained from each activity are also summarized. The IRPA YGN will aim to achieve its on-going activities and continue to follow the ways paved in the Strategic Agenda and despite the challenges raised by the COVID-19 pandemic. Namely, running an international survey (for example, on the usage of social media in radiation protection, and on the long-term consequences of the COVID-19 pandemic), engaging national YGNs, extending the network, finding new relationships with networks with an interest in the young generation and participation in (remote) events will be aspired for.

  • This study was carried out to construct a DNA profile database of 100 strawberry cultivars using microsatellite markers. Two hundred seventy four microsatellite primer pairs were screened with a set of 21 strawberry cultivars with different morphological traits. Twenty five primer pairs were selected because they produced reliable and reproducible fingerprints. These primer pairs were used to develop DNA profiles of 100 strawberry cultivars. Three to thirteen alleles were detected by each marker with an average of 7.50. The average polymorphism information content varied from 0.331 to 841 (average 0.706). Cluster analysis showed that the 100 cultivars were divided into 7 major groups reflecting geographic origin and pedigree information. Moreover, most of the cultivars could be discriminated by marker genotypes. These markers will be useful as a tool for the protection of plant breeders' intellectual property rights in addition to providing the means to intervene seed disputes relating to variety authentication.

  • The number of high-rise buildings and skyscrapers has increased drastically, and accordingly, the power capacities and main line lengths of electric power systems for fire protection are also rapidly increasing. This is generating new of problems like shortages in power capacities and increases of main line voltage drops outside of the rated voltage range. This problem can have serious effects on fire protection systems and a variety of electric devices may not work properly in emergencies. As such, theoretical calculations were performed for these systems in an actual fire protection facility. The problems in the electric power system were extracted and analyzed, and the results show that it is necessary to search for new measures for the safe and rational design and operation of electric power systems for fire protection.

  • Many cultural heritages for the modern ages in Korea are becoming lost rapidly as a result of subsequent technological innovation and changes in industrial structures and other reasons. But they are indispensable for an understanding of history, tradition culture of Korea, and form the basis for development and advancement of future culture at the same time. Therefore, this study is aimed to review the protection of cultural heritage in Japan, establishing the protection policies in Korea. In Japan, The Advisory Committee for the Preservation and Utilization of Modern Cultural heritage was organized by The Agency for Cultural Affairs. And this classified modern cultural heritage into four fields, as like; (1)monuments, (2)buildings, (3)fine arts and historical heritage, and (4)life, culture, and technology to pursue concrete research and study. The next step is tarrying out investigations to identify these cultural heritages, which were once the backbone of Japanese modernization and are now in the process of being lost, in an effort to preserve them as cultural heritage of the Japanese modernization period. The investigation will have conducted on an about eight year scheme starting with 1996. And it's will ask all local boards of education(of the prefectures, cities, towns, and villages throughout the country) to supply all related records or documents available and to cooperate in field studies. So now, many cultural heritages for the modern ages in Japan have been designated as Important Cultural Properties, Registered Tangible Cultural Properties, Monuments, etc. And they have been prepared various tax policy(ex, reduction of the real estate tax). Also, that's examples are not only one by one but magnified with protection of large-scale construction associated with region. In addition, magnified with region's activities. In conclusion, in the process, protection has been extended to a broader variety of cultural properties and much consideration has been given to the methods of protection in Japan.

  • It is a general trend in the world that female workers are drastically increasing due to the facts that highly developed capitalism requires women's job, women are inspired to work, housewives can shorten their working hours for house-keeping and save their energy from their routine works, educational expenses of their children become larger, large among of modities has stimulated purchasing desire. Since the International Treaty on Prohibition of Female's Night Labor was agreed at the Bern's Conference in 1906, the International Labor Organization (I.L.O.) established after the World War II, has adopted innumerable international labor treaties. According to the laws of the advanced countries, the first priority of their protection has been placed on juvenile and female workers. The legal protection of female workers and equal treatments such as wage and promotion between men and women have become important world problems. In this thesis, the great principle of the Labor Standard Law, protection regarding working house, risk and harm in performance of jobs, protection of mother-workers, protection of women workers in advanced countries and the present status of welfare facilities for women workers in our country will be studied. The most important points this thesis has placed stress and appealed, are as follows : 1. The scope and variety of women workers' jobs should be broadened. 2. Opportunity for promotion should be guaranteed for women workers based upon the ability and capacity of individual woman worker. 3. Equal wage principle between men and women workers, should be established based upon the idea that men and women should be equal. 4. The age limit or marriage limit of employment applied only to female workers, should be abrogated. 5. The ability of middle and old aged women workers should be developed and utilized to the maximum extent. 6. Welfare facilities for women workers, should be urgently secured and guaranteed.
