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 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

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.
