The purpose of this study were to analyze the research trends about the regional bio-resources of the Chungcheongnam-do. Chungnam were made up to 15 area (8 cities and 7 guns) but this study included Yeongi-gun that was included in Sejong-city. We are collected 175 papers through Google or Research Information Sharing Service (RISS) of Korea etc. and were analyzed articles published from 1974 to 2018. The most studied bio-resources in the Chungnam area was the ginseng of Geumsan-gun. Seosan-city was the region with the largest number of types of biological resources. When the publication year of the paper was divided into five years, the most published(total 63 papers) period of the paper was between 2009 and 2013. During this period, most of the papers using bio-resources of Geumsan-gun were published (12 articles). Of the 63 papers, 24 papers were fruit materials, and fruit bio-resources were the most used

Alignment of the mirrors composing a space telescope is an important process for obtaining high optical resolution andperformance of the camera system. The alignment of mirrors using cube mirrors requires a relative coordinate mapping betweenthe mirror and the cube mirror before optical-system integration. Therefore, to align the spacecraft camera mirrors, the relativecoordinates of the vertex of each mirror and the corresponding cube mirror must be accurately measured. This paper proposesa new method for finding the vertex position of a primary mirror, by using an optical fiber and alignment segments of acomputer-generated hologram (CGH). The measurement system is composed of an optical testing interferometer and a multimodeoptical fiber. We used two theodolites to measure the relative coordinates of the optical fiber located at the mirror vertex withrespect to the cube mirror, and achieved a measurement precision of better than 25 μm.

The purpose of this study was to develop the evaluation instrument for sensible aspects of housing environment. In terms of importance of sensibility which people persceive their housing environment, researches on the sensible environment has been done in several academic fields. However, evaluation tool for sensible aspects of housing environment has not existed until now. Therefore, there is a need to develop evaluation tool to measure the fit between dwelling environment and human sensibility. For this purpose, this study reviewed literatures and test results about ergonomics and human factors according to five senses. Based on keywords about five senses and housing environment, a checklist was developed.

The purpose of this study was to analyze the previous research in accordance to research type, research purpose, and research method. The focus of this research analysis was on master's thesis and doctoral dissertation published in decades, and the keyword used in the search was exclusively limited to terms in relation to healing garden. The research method adopted in this study was content analysis.

국립수산진흥원의 격월별 17년간(1967∼1983) 37개 정점의 해양조사 자료를 이용하여 한국 동해안 의해 표층 200m 해수의 열적 구조와 수온의 시공간적 변동을 구명하였다. 표층(0∼200m)과 아표층(100∼200m)의 수온 변동을 분석하여 도출된 주요 결과는 다음과 같다. 표층에서의 수온 변동은 주로 1년 주기의 계절적 변동이 대부분이지만, 아표층의 수온 변동에서는 비계절적인 변동이 우세하다 하지만, 계절적인 예년변동치를 제거한 수온 이상변동의 경우, 표층과 아표층의 수온 이상변동은 시간적으로 밀접한 상관관계가 있을 뿐만 아니라 공간적인 분포도 유사성이 크다. 아표층의 수온 변동은 1년 주기 이외에 14개월과 70개월의 탁월주기를 가진다. 아표층에서 나타나는 14개월 주기의 수온 변동은 극조(pole tide, Chandler wobble)의 주기와 일치한다. 아표층 해역 수온 변동에 대한 군집해석에 의하면, 이 해역은 한류역, 천이역 및 난류역으로 구분된다. The thermal structures and their spatio-temporal fluctuations in the upper 200m layer off the southeast coast of Korea are studied using the bimonthly temperature data for 17 years(1967∼1983) at 37 stations. We analyzed the fluctuations of the temperatures in the surface(0∼100m) and in the subsurface(100∼200m) layers. The fluctuations of temperatures in the surface water are dominated by the annual variation, whereas the subsurface layer temperatures contain considerable non-seasonal fluctuations. The distributions of water temperature anomalies in the subsurface layer are closely related with those in the surface layer. The predominant periods of temperature fluctuations in the subsurface layer, other than the annual variation, are 14 and 70 months. The period of 14 months coincides with that of the pole tide or Chandler wobble. The cluster analysis shows that our study area can be divided into the cold, the frontal and the warm regions.
