Objective : The purpose of this study was to establish the concurrent validity of the Korean Occupational Balance Assessment(OBA) tool. Methods : This study was conducted on 1016 people from October 1 to October 25, 2019. Data collection was performed using OBA and Occupational Balance Questionnaire11(OBQ11). The data were analyzed by descriptive statistics, Pearson correlation. Results : There was a significant correlation between the scores of the three areas of OBA and the total score of OBQ11(p<.01). All three areas were analyzed with positive correlations. The time use area (r = .554) and occupation frequency area (r = .574) were found to be correlated. Most of the sub-factors in the occupation characteristics area (importance r = .582, goal achievement r = .633, enjoyment r = .649, health r = .650) were analyzed with high correlation. Conclusion : OBA has proven to be a valid and reliable assessment tool for measuring occupational balance. Further research needs to provide guideline on occupational balance for usefulness in clinical area.

Until now, the study of fine dust has been divided into prediction, analysis and measurement, mainly in the field of atmospheric environment. Fine dust is caused by various causes such as atmospheric quality factor, meteorological factor and emission. It was determined that it was a priority to analyze the correlation of how much each element affects fine dust, and it was experimented. This correlation analysis was done using IBM SPSS tool using air quality factor and meteorological factor data obtained from Korea Meteorological Administration and Air Korea. As a result, the influence of air quality factors and meteorological factors on the fine dust level was more clearly understood. In this paper, we present experimental results as correlation analysis and pearson coefficient for more precise analysis between PM10 values and affected factors.

This paper proposes the new electric power demand forecast model which is based on an artificial neural network and considers time and weather factors. Time factors are selected by measuring the autocorrelation coefficients of load demand in summer and winter seasons. Weather factors are selected by using Pearson correlation coefficient The important weather factors are temperature and dew point because the correlation coefficients between these factors and load demand are much higher than those of the other factors such as humidities, air pressures and wind speeds. The experimental results show that the proposed model using time and seasonal weather factors improves the load demand forecasts to a great extent.

This study was to determine the relationship between nurse DISC personality types, self-efficacy, clinical performance. Data were collected from 302 nurses in 5 hospitals in K city. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient. With regard to self-efficacy and clinical performance, D type showed a higher score than type I type and S type. The lower region of the clinical performance showed the nursing process, nursing skills, higher score than the D Type S Type in professional development. With regard to personality and self-efficacy, and clinical performance, the type D (r=.56, p<.01), I type (r=.66, p<.01), S type (r=.6, p<.01) showed a positive correlation with type C (r=.52, p<.01). As shown by these results, each personality type has a different correlation with self-efficacy and clinical performance ability. This factor should be considered in the assignment of nurses to departments or individual training programs so that they can deliver the most effective job performance.

물리ㆍ화학적 및 효소적 방법을 이용한 근육의 품질판정 지표로써 수분함량, 지질함량 그리고 콜라겐 함량등을 살펴보았으며, AEC 수치로써 건강도를 측정하고자 하였다. 즉, 이런 지표들을 이용하여 양식산 활어의 품질에 가장 큰 요인으로 작용하는 파괴강도와의 상관관계를 살펴보고자 하였다. 지금까지 조사된 양식산 활어성분 중 파괴강도가 어떠한 독립변수들에 의하여 크게 영향을 받으며, 파괴강도와 독립변수와의 관계식은 무엇인가를 규명하기 위하여 회귀분석을 실시하였다 여기서 독립변수로 사용된 것은 아래와 같다. X$_1$ : 수분함량(moisture content) X$_2$ : 지질함량(lipid content) X$_3$ : 콜라겐 함량(collagen content) 각 성분간의 상관관계를 피어슨 상관계수로 나타낸 것으로, 파괴강도와 수분 함량, 지질함량사이에는 상관성이 있으나(r=0.66, r=-0.69: p<0.05), 콜라겐의 함량과는 상관성을 가지지 못하였다. 또한, 콜라겐과 수분함량(r=0.19), 콜라겐과 지질함량(r=-0.29)로 각 성분간의 상관성이 존재하지 않았다. 그러므로, 파괴 강도값은 지질과 수분함량간의 상관관계가 형성된다. 즉, 수분함량이 크고 지질함량이 작아지면 파괴강도간은 커진다는 결론이다. 이 결과를 이용하여 파괴감도, 수분함량 그리고 지질함량간의 회귀분석을 실시한 결과 다음과 같다. Y = 0.74481 ＋ 0.01323 X$_1$- 0.05821 X$_2$ 이 회귀식을 이용하여, 참돔의 수분함량과 지질함량을 측정함으로써 참돔의 품질을 결정할수 있는 파괴강도값이 계산으로 얻어진다. 또한 효소적방법으로써 품질지표인 AEC수치를 측정함으로써 건강도를 판정할 수 있다. 그러므로, 파괴강도값을 이용하여 품질의 등급을 선정하며, AEC수치를 건강도의 등급을 선정하여야 된다. 파괴강도값에 의한 등급은 1.4kg이상은 상급, 1.2~l.4kg은 중급, 1.2kg이하를 하급으로 선정하며, AEC수치는 1.0~0.9는 상급, 0.9~0.8는 중급, 0.8이하를 하급으로 선정하여 등급화를 분류할 수 있을 것으로 판단된다.

This study aimed to investigate the correlation between the inclinations of the incisors and lips in mixed dentition aged 7 - 11 years. Lateral cephalometric radiographs of 353 children were analyzed to measure the upper incisor inclination, lower incisor inclination, lower-nasolabial angle, and mentolabial angle in relation to the skeletal malocclusion classification. The measurements were then assessed using the Kruskal-Wallis test, Pearson correlation, and multiple regression analysis. There were significant negative correlations between the inclination of the upper incisors and lower-nasolabial angle in all classes of skeletal malocclusion. There was a negative correlation between the inclination of the lower incisors and mentolabial angle; however, class II malocclusion had a significant positive correlation. This study identified the factors that affect lip inclination and verified their associations.
