요가지도자의 지도유형이 수련생의 운동몰입과 생활만족에 미치는 영향
최수안(Choi, Su-An),김형진(Kim, Hyung-Jin),윤용진(Yoon, Yong-Jin) 한국체육과학회 2015 한국체육과학회지 Vol.24 No.2
The purpose of this study was to clarify the influences among yoga instructors’ leadership style, exercise flow and life satisfaction. The subjects of this research were the yoga trainees who participated in 2014 Korea Yoga Conference, and 297 subjects were sampled through convenience sampling method. In order to achieve this study, the data were analyzed by frequency analysis, reliability analysis, exploratory factor analysis, and correlation analysis and multiple regression analysis using SPSS Version 21.O. program. The results were as follows: First, the instructors’ leadership style had an influence on exercise flow. Second, the instructors’ leadership style had an influence on life satisfaction. Third, the exercise flow of yoga trainees had an influence on life satisfaction.

아파트 매매가 추이 예측에 관한 연구: 정부 정책, 경제, 수요·공급 속성을 중심으로
이중목 ( Jung-mok Lee ),최수안 ( Choi-Su An ),우수한 ( Su-han Yu ),김성훈 ( Seonghun Kim ),김태준 ( Tae-jun Kim ),우종필 ( Jong-pil Yu ) (사)한국빅데이터학회 2021 한국빅데이터학회 학회지 Vol.6 No.1
Despite the influence of real estate in the Korean asset market, it is not easy to predict market trends, and among them, apartments are not easy to predict because they are both residential spaces and contain investment properties. Factors affecting apartment prices vary and regional characteristics should also be considered. This study was conducted to compare the factors and characteristics that affect apartment prices in Seoul as a whole, 3 Gangnam districts, Nowon, Dobong, Gangbuk, Geumcheon, Gwanak and Guro districts and to understand the possibility of price prediction based on this. The analysis used machine learning algorithms such as neural networks, CHAID, linear regression, and random forests. The most important factor affecting the average selling price of all apartments in Seoul was the government’s policy element, and easing policies such as easing transaction regulations and easing financial regulations were highly influential. In the case of the three Gangnam districts, the policy influence was low, and in the case of Gangnam-gu District, housing supply was the most important factor. On the other hand, 6 mid-lower-level districts saw government policies act as important variables and were commonly influenced by financial regulatory policies.

Linoleic acid의 酸化에 의한 活性酸素種의 生成
최수안 부산교육대학교 과학교육연구소 1989 科學敎育硏究 Vol.14 No.-
The Formation of superoxide anion(·O_2^-)and hydrogen peroxide(H_2O_2) during linoleic acid peroxidation were investigated in linoleic acid-aqueous system at 37℃. Superoxide anion was rapidly generated in the early stage of peroxidation, marked to 0.375(absorbance at 560mm) in the 12mM linoleic acid(POV below 80millieq/kg) incubated for Ⅰ day and then decrased with time-elapsed. Hydrogen peroxide was also rapidly generated in the early stage of peroxidation regardless of linoleic acid concentration. And, superoxide dismutase (SOD) and catalase greatly inhibited the formation of superoxide anion and hydrogen peroxide, respectively.

Malonaldehyde 및 Hexanal의 DNA 損傷作用
崔守安 부산교육대학교 과학교육연구소 1990 科學敎育硏究 Vol.15 No.-
The damage of plasmid DNA by malonaldehyde and hexanal to elucidate the DNA damage mechanism by lipid peroxidation products was investigated through 1% agarose gel electrophoresis. DNA damage was induced by malonaldehyde and dexanal, byt its mechanism was due to the formation of the DNA-carbonyl compound complex, not to the scission of DNA strand. And there was not the effects of avtive oxygens on the DNA damage by malonaldehtde and hexanal.

홍합(Mytilus Rassitesta)은 각 지역즉 포항, 부산, 충무, 여수등지의 해안에서 5m 떨어진 수심 3m 근처의 암초에 서식하고 있는 것을 채취하고 각지역별에 따라 중금속의 함량을 정량하였다. 그 함량의 상태는 동해안 서해안 남해안 순서로 중금속의 함량이 차가 약간 있다. 함량 범위를 보면 Cd 0.01∼0.017PPm. Cu가 0.12∼0.23PPm로 되여 있다. 앞의 결과 고찰에서 말한바 같이 이번 조사대상의 시료에서는 중금속함량이 식품으로서 그다지 문제가 되지 않은 함유량으로 사료된다. 끝으로 본 실험에 협조하여 준 보건소장님께 감사드립니다. I analyzed to quantity the heavy metal which is contained within sea mussels taken frome East, Sauth, and West coast of Korea. They were taken from October, 1977∼July, 1978 and analyzed by A,A,S. result. 1. They contained 0.8PPm∼1.14PPm of Cu. Specially, South coast was high Than the other Ones(the allowance quantity in Japan is 2PPm) 2. They contained 0.1PPm∼0.17PPm of Cd. South Coast ones were high than the others(the allowance quantity in the U.S.A. is 1.5PPm) As shown above results even though the heavy metals are not A ceeded the allowance quantity. We need to keep our environment Clear.

植物油의 Triglyceride 組成에 관한 硏究 : 올리브기름의 Triglyceride 組成
최수안 부산교육대학교 과학교육연구소 1984 科學敎育硏究 Vol.9 No.-
Triglyceride fraction was separated from olive oil by thin layer chromatography (TLC) and fractionated into four groups by high performance liquid chromatography(HPLC). Compositions of the triglycerides and fatty acids of four fractions were determined by gas liquid chromatography(GLC). The olive oil contained higher concentrations of C-52 and C-54 triglycerides having partion numbers of 48. The fatty acid compositions of these triglycerides were mainly composed of C18:1 and C18:2 fatty acids. From these results, the possible fatty acid combinations of major triglycerides of olive oil were estimated to be (3C18:1;50.6%), (1C16:0, 2C18:1;23.51%), (2C18:1, 1C18:2;5.48%), (1C18:0, 218:1;4.55%), (1C16:0, 1C18:1, 1C18:2;2.94%), (2C16:0, 1C18:1;2.35%), (1C16:1, 2C18:1;2.21%), (1C18:1, 2C18:2;1.06%), (1C14:0, 2C18:1;1.03%).
