Korea is closed to China in the geographical position and is related to China as two countries have developed similar culture, art, and social systems. Architecture is a kind of culture and has advanced in the wooden architecture with a considerable change. The study investigated a phylogenetic relationship between two countries based on characteristics of architectural universality. With comparison and analysis on the common feature and difference of the beam and structure in the wooden architecture from the Koryo and Zhejiang Province(China), the systemicity of the wooden architecture was examined. The beam is a part of timber which is consist of the wooden structure frame and also a crucial subject to understand a development process of the wooden architecture.

Although a table of descent is a mandatory primary source for studying medical persons, but most of those who practiced medicine were not but of step families. Because members of step families are not usually recorded accurately, preceeding studies did not put much emphasis on them. But as more researchers study biography and the number of studies done on historical figures are increasing tremendously, its value as a source has increased as well. In order to research a person, obtaining background information is a priority, which includes to what family they belong to, to what specific branch of the family they belong to, etc. Whether or not the person has ever worked with a public institution is important as well.

최근 통계적 소양, 추론, 사고에 중점을 둔 통계 교육의 필요성이 강력하게 제기되었다. 특히 통계 교육의 목적으로서 통계적 소양의 중요성이 주목을 받고 논의되고 있다. 이에 따라 선행연구를 중심으로 통계적 소양에 대해 고찰하고자 한다. 그동안 논의되었던 통계적 소양의 정의, 구성요소를 살펴본다. 그리고 학교 수학교육과정에서 통계교육의 목적을 살펴보고, 통계적 소양의 측면에서 우리나라의 통계 교육을 위한 시사점을 생각해 본다.

The purpose of this study is to develop a method for establishing an educational system for World Heritage interpretation applicable to World Heritage sites and to design an education program for World Heritage interpretation by applying the developed education system in this study. This study first identified the definition of interpretation and the relationship between interpretation and education through previous research and analyzed the role and significance of heritage interpretation due to the paradigm transition in the capacity building of World Heritage sites. Next, the educational status of World Heritage interpretation was analyzed through educational institutions, educational subjects, and curriculum examples. Finally, this study argues that a method for establishing a World Heritage interpretation education system should be presented according to the composition of the curriculum, and the interpretation curriculum planning by interpreters should be proposed focusing on the Outstanding Universal Value (OUV) of World Heritage sites.

시공단계를 고려한 곡선변단면 프리스트레스트 콘크리트 박스거더교량의 해석을 수행하였다. 곡선변단면 박스요소를 사용하며 시공순서에 따른 구조계의 변화, 크리이프, 건조수축과 릴렉세이션 등의 효과를 고려하였다. 사용되는 단면형상은 양쪽에 캔틸레버를 갖는 직사각형 1실 박스단변이며 부재축은 평면상의 곡선으로 단면제원은 부재축을 따라 변할 수 있다. 각 요소는 3절점으로 구성되며 각 절점은 단면 찌그러짐과 ?을 포함하는 8자유도를 가진다. 본 연구에서 여러가지 경우의 예를 해석, 비교하였으며 실제교량에의 적용 가능성을 입증하였다.

This study aimed to investigate early life of Coreoperca herzi living in Han River and compare morphological differences between different groups during the development in order to provide basic data for relevant taxonomic research. On average, one female individual spawned 541 to 861 eggs (average 701) at once. After 259 hours, the tail broke out of the egg membrane and hatching began. Immediately after hatching, the larvae were average 7.81±0.10 mm (n=5) in total length. 60 days the juvenile was average 35.9±1.30 mm (n=5) in total length. The white spots spread to the rest of the body, rending the same pattern as that on the body of their broodstock fish.

Field and laboratory works were conducted to Investigate the life history, ginseng damage and chemical control effect of the field slug, Deroceras varians A. Adams. D. varians laid eggs from April to June, but a small number of eggs were also found from July to September in the field. Most young slugs grew through the slimmer months to maturity by October. overwintered beneath the moist soil surface, and began feeding and egg-laying in the following April. indicating that D varians have a life cycle in a year. Damage of ginseng plants by D. varina occurred mainly from late April to mid May in the 3rd to 5th year ginseng fields with rice-straw mulching. It seems that this damage is caused by the adults in oviposition periods and related to rice-straw mulching of ginseng fields. In the experiment, ethoprop 5% granule and metaldehyde 6% bait showed relatively high effectiveness in the control of D. varians adults. Bordeaux mixture was more effective when the chemical was sprayed after infestation of the slug than before the infestation and when the 6-12 mixture was used.

The purpose of this study is to explore the history of the relationships between Japan and the Pacific Island Nations in the context of its ocean policy, and to survey the current situation. Particularly, this paper inquires into how Japan's maritime policy, nuclear policy, and official development assistance policy have affected relationships with countries in this region. Firstly, this paper gives a brief overview of the socio-political situations of Pacific Island Nations. Secondly, the history of the 'Southward Advance Theory' adopted as national policy by Japan in the Meiji era is summarized. Thirdly, how Japan successfully re-entered this region despite conflicts surrounding the nuclear issue after the Second World War is explored. Lastly, this paper investigates how official development assistance and PALM (Pacific Island Leaders Meeting) helped to develop relations between Japan and the Pacific Island Nations.
