In order to investigate the variations on the seed hardness of Pisum sativum distributed in southern area of Korean peninsula, 10 local strains (Choonseong. Ganghwa, Pocheon, Hadong, Haman, Geumneung, Yeongyang, Boseong, Gochang, Namweon), which located from $34^{\circ}26"N$ to $38^{\circ}11"N$, were selected according to their latitudes and geographical distances. The seeds of these strains were collected and their contents of mannose and galactose were analyzed. Mannose contents in the seeds were variable in the range between the highest 10.351 mg/g (Ganghwa) and the lowest 5.962 mg/g (Yeongyang). The contents of galactose were also represented remarkable differences from 7.050 mg/g (Yeongyang) to 19.314 mg/g (Hadong). The local strains were classified into 3 variation types such as the south central type (Namweon, Yeongyang, Geumneung, Gochang), the central type (Choonseong. Ganghwa, Pocheon) and the southern type (Haman, Hadong) and 1 strange strains (Boseong) according to the geographical climatic type, isopleth of warmth index and the ratio of mannose to galactose, which indicate the hardness of seeds in Leguminosae, ranged from 0.46 to 0.94. The variation types are very significant genecologically as an evidence for microevolution related to natual and artificial selection in cultivated plants.

This paper presents several reasons for the necessity of archaeological hands-on training and strategies for its implementation. First, it is necessary to produce a specialized manual for local cultural heritage education that can enhance the specialization and educational effectiveness of archaeological experience education. In addition, in order to secure professionalism in hands-on education and conduct it systematically, the ability of instructors to conduct education is important, so instructor competence reinforcement education needs to be conducted regularly. In addition, hands-on education needs a strategy of planning and content development of archaeological education programs, with consideration given to the subjects of learning, and the establishment of a cooperative network. It is time to cooperate with various experts to establish an education system necessary for cultural heritage education in the region and develop customized content for local archaeological heritage supplementary textbooks. Finally, due to Covid-19, we agonized over effective education plans for online archaeological heritage education, which requires active interaction class design and a strategy to promote interaction between professors and learners. In addition, such archaeological heritage education should be compatible with the goal of providing customized lifelong education.

This study was originated from the idea that it would be important for caring service of community children center to be positioned as the institution to strengthen the public nature and provide quality care services to children. In particular, competencies of the employees in community children centers play an important role and the quality of children care services is the crucial evaluation parameter for those institutions. The objectives of this study are to investigate the effects of the competency levels of the employees in community children centers on the service quality to children and to verify the mediated effect of self-efficacy on their service quality to children. With respect to the data analysis methods, hierarchical regression analysis was performed. Barron & Kenny's method was used to understand the mediated effect of self-efficacy. Also, Sobel test was performed to investigate the significance of mediated effect of self-efficacy. The study results are, first, the service quality to children might be differed by the level of competencies of the employees in community children centers; and second, partial mediated effect of self-efficacy was found between their competencies and service quality to children. These results implicate that service quality to children can be improved by strengthening competencies of the employees in community children centers and enhancing their self-efficacy. It is necessary to try to improve the service quality by enhancing competencies and self-efficacy of the employees in community children centers, which will lead those institutions to play a crucial role in the caring services.

Since the launch of WTO. the global telecommunications market has been accelerated to ensure interoperability between the various telecommunications or services and this effort is emerging as the realization of an importance of standardization. In addition, in recent years as standardization is recognized not as just a means of ensuring interoperability but as a key strategic means of economic survival in the new trade order at the international regional, and national levels. Thus, each country is working actively to process telecommunications standardization through such means as multilateral cooperation and collective counter-strategies, which are mapped out, in the various regional and global fora and consortia. In keeping with these trends, Asia-Pacific Telecommunity, which is taking charge of telecommunications affairs of Asia-Pacific region, has been pursuing not only regional common interests but enhancement of its status in the world market by standardization on the basis of intimate collaboration, obtained by establishing regional standardization organization named ASTAP(APT Standardization Program). Bearing in mind the consideration outlined above, this paper aims to analyze telecommunications standardization policy intended by Asia-Pacific regional standardization organization and accordingly, to suggest a strategy for strengthening telecommunications standardization activities in Asia-Pacific region.

The different compliance concentration of effluent limit is applied to effluent discharged from public sewage treatment works(PSTWs) in each watershed on the basis of water quality thereof in accordance with the enforced Watershed Sewer System Maintenance Plan in 2013. It is necessary to set the compliance concentration of effluent limit for PSTWs in watershed sewer system, in order to achieve water quality criteria for regional watersheds or target water quality under TMDL program. Watershed Environmental Agencies establish the Watershed Sewer System Maintenance Plan and set the compliance concentration of effluent limit for PSTWs under the plan. The agencies have a plan to apply strengthened effluent BOD concentration limits for PSTWs in I to IV area grade, respectively. Effluent BOD concentration limits will be strengthened from 5~10 mg/L to 3 mg/L in II~III area grade, from 10 mg/L to 5 mg/L in IV area grade. Uniform application of effluent BOD concentration limits to PSTWs in the watershed sewer system need to be complemented considering type of sewage treatment technology employed and watershed characteristics. Therefore, this study presents assessment methodology which analyze for the compliance concentration of effluent limit to affect water quality of discharge watershed using simulation model for the Jinwee-stream watershed.
