The basis of all approaches to improve reliability of marine engines exists in analyzing the field data of troubles and failures in marine engines. In this paper, we analyzed the engine accidents of Korean fishing vessels for five years from 1995 to 1999, firstly according to engine systems, type of fishing vessels, engine makers, cylinder number, engine power and tonnage, secondly by using of principal component analysis method, one of multi-variate data analysis method. Finally, we proposed the measures to reduce engine accidents of fishing vessels for improvement of an environment in fishing industry.

Purpose: This study was done to determine the risk factors for recurrent fallers (2+falls) compared to single fallers. Methods: Participants were 104 community-dwelling people 65 yr of age or older. The data were collected from June 1, 2008 to June 30, 2009 using the Residential Assessment Instrument-Home Care. Results: Over the past 90 days, 55.7% of the 104 participants fell once, and 44.2% experienced recurrent falls (2+falls). In comparison of recurrent fallers with single fallers, there were significant differences in scores on the following factors: gender ($X^2$=4.22, p=.040), age ($X^2$=5.74, p=.017), educational level ($X^2$=5.22, p=.022), living arrangements ($X^2$=35.02, p<.001), cardiovascular diseases ($X^2$=17.10, p<.001), hypertension ($X^2$=4.43, p=.035), diabetes mellitus ($X^2$=4.44, p=.035), glaucoma ($X^2$=13.95, p<.001), Minimal Data Set (MDS)-Pain (t=-2.56, p=.012), fear of falling ($X^2$=4.08, p=.034), reduced vision (t=-3.06, p=.003), MDS-activity of daily living (t=3.46, p=.001), MDS-Instrumental Activities of daily living (t=3.24, p=.002), cognition (MDS-Cognition Performance Scale) (t=3.40, p=.001), and 'difficulties entering and leaving the house' ($X^2$=4.53, p=.033). Conclusion: It is important to assess the risk factors for recurrent falls and develop differentiated strategies that will help prevent recurrent falls. Additionally, utilizing a standardized tool, such as RAI-HC, would help health professionals assess multi-variate fall risk factors to facilitate comparisons of different community care settings.

Purpose: This study was done to identify and compare factors associated with intention to receive Human Papillomavirus (HPV) vaccine between male and female undergraduate students. Methods: In the fall of 2010, 479 students responded to self-administered questionnaires about their intention to receive HPV vaccine, HPV knowledges, HPV related involvements and optimistic bias, subject's characteristics including opinion about HPV vaccine. Mann-Whitney U test, uni-variate and multi-variate logistic regression were used for data analysis with SPSS/WIN. Results: Intention to receive vaccine were 22.0% of men and 25.0% of women. There were significantly different in HPV knowledge (Z=-2.74, p=.006), optimistic bias (Z=-4.60, p<.001), vaccine is necessary for women (Z=-4,30, p<.001), vaccine is necessary for men (Z=-4.37, p<.001), vaccine is necessary if only symptom exist (Z=-4.52, p<.001), but there were not different in intention to receive vaccine, involvement between men and women. Concern about vaccine safety (OR=3.19, 95% CI 1.63~6.23) was determinant of intention to receive HPV vaccine for men. Conclusion: This study showed gender differences in HPV knowledge, HPV related optimistic bias and opinion about HPV vaccine, which would be assessed and well managed in tailored HPV education for enhancing HPV vaccine acceptance.

1968년에 발표된 구식 싱글턴 혼합기수 고속푸리에 변환 포트란 서브루틴에 존재하는 일반적인 $N$ 문제에 대한 간단한 처치법을 제안하였다. 주어진 문제에 대한 간략한 검토를 마친 후에, 새로운 처치법을 동적메모리 할당방법의 입장에서 최악상황분석법을 통해 논의하였다. 본 논의를 통해 여기서 제시된 프로그래밍 기법은 최소한 다차원 데이터 집합에 대해 지금까지 제시된 여타 처치법보다 우월함을 보였다.

본 연구에서는 전국 59개 지점의 3개월 SPI 자료를 가지고 EOF를 유도하고 아울러 그 공간적 특성을 분석하였다. 또한 EOF 해석에 의해 나타난 Coefficient Time Series를 다변량 시계열 모형에 적용하여 SPI 시계열을 자료기간 10,000년으로 확장하였고 전국적인 가뭄심도를 판단하기 위해 전국 평균 지수를 이용하여 재현기간별 최대심도를 결정하였다. 마지막으로 각 대권역의 댐 유효저수량과 농경지 면적을 이용하여 농업가뭄 대비능력을 판단하였는데 재현기간 30년 가뭄에 적절히 대비할 수 있는 이수능력을 갖춘 유역은 한강유역이 유일한 것으로 파악되었다. 특히 영산강 유역은 큰 농경지 면적에 비해 저수용량이 크게 부족한 것으로 파악되었고 강우량의 크기에 민감한 농업가뭄에 가장 취약할 것으로 나타났다.

본 연구에서는 학교 장면에서 학생들의 디지털 게임 이용에 대한 교사의 수용도가 어떻게 구성되어 있는지를 살펴보고, 교사의 수용도에 영향을 미치는 요인에 대해 알아보았다. 이를 위해 2016년 8월 설문조사를 실시하였고, 초, 중, 고등학교 교사와 상담교사, 전문 상담사, 총 250명의 자료가 분석되었다. 그 결과, 학생들의 디지털 게임 이용에 대한 교사의 수용도는 5개의 하위요인인 관리/감독의 필요성, 적극 활용의사, 관심과 확인, 부적응 대체활동으로 인정, 수용 효능감으로 구성되어있었다. 다변량다중회귀분석방법을 통해 분석한 결과, 교사의 연령, 디지털 미디어 리터러시의 하위요인 중 공동체성과 탈규범성, 학생들의 디지털 게임 이용에 대한 교사 태도와 디지털 게임이 학업에 미치는 영향에 대한 교사 평가가 교사의 수용도 5개 하위요인에 차별적으로 영향을 미치는 것으로 확인되었다. 본 연구는 교육적 잠재력이 강조되고 있는 디지털 게임에 대한 교사의 수용도가 어떻게 구성되어있는지를 구체적으로 확인하고, 교사의 수용도를 촉진하는데 영향을 주는 주요 요인들을 밝혔다는데 그 의의가 있다.

Simple correlation analysis, factor analysis, and multi-verite analysis have been performed to analyze the relationship between air pollution and meteorological factors for air pollution and meteorological data measured at Kwanghwamun in Seoul during the period of one year (January 1990" December 1990). As a result of simple correlation and factor analysis, $SO_2$, TSP and CO concentrations have shown high negative correlation with temperature and among these indicating that these are related with pollutants emission trend based upon heating fuel usage. Ozone has a good correlation with solar radiation and relative humidity to have a closed relation with $0_3$ generation reaction mechanism. The result of multi-variate correlation analysis shows that the concentration of $SO_2$ and CO are adequate for correlation model with ambient temperature and wind speed and 0$_{3}$ concentrations are adequate for that with solar radiation and wind speed. $SO_2$ and CO levels are considered to be affected first of all by heating fuel usage as a emission source and wind speed as a dispersion effect. The $SO_2$ concentration in the condition that the temperature fall below zero is explained by multiplicative model with wind speed, only one variable.

Objectives: This study aimed to analyze the association between adolescent depression and personal factors such as interpersonal relationship and personal characteristics. Methods: The data used for this study was taken from the 2014 Korean Children and Youth Panel Survey. Of those 2,351 subjects in a data set, data of 1,938 subjects were analyzed after excluding 413 subjects with missing information. Hierarchical regression analysis was conducted for multi-variate analysis. In addition, controlling effects of ego-resiliency was analyzed. SPSS 22.0. was utilized for statistical analyses. Results: The study found that the depressive index was higher in women than men, and lower in adolescent who has a good relationship with parents and friends. This study also found that adolescents with high ego-resiliency are more vulnerable to depression. Conclusions: It is recommended to understand and to utilize ego-resiliency of adolescents, in order to reduce adolescents depression. Promoting good relationship with parents and friends will also positively impact to lower adolescents depression.

Evaluation of the work of art with intention of the artist different is not a possibility of free oneself from the limit which estimates an evaluation at value of appreciator. We tried new interpreting about the work of art in this paper. The work of art respects the intention of the artist to make it and interprets intention until now. After critics distinguish by a period, an area that they set to philosophical thought which is the time and interpreted. We set to each one subjectivity and interpreted between artist to make the work of art and appreciator. But in this paper, we tied various criteria which appreciates the work of art. We tried so that we presented the intimacy each other newly. Otherwise we tied with the subjectivity of the individual and are the try to be an objectification low through statistical technique. We looked into the culture and art in the introduction and explain the discussion about the work of art interpreting which the main subject. We set the category 6 area, and explain an each criteria explanation and assessment method. We tried to propose new interpreting as the intimacy to be multivariate data analysis result of the assessment analysis. Stopping from the thing which sees the work of art knows, it will be able to give meaning thing from this research prerequisite.
