The purpose of this study is to examine the factors that affect the social competence of young children and to promote the social competence development of the age group. The study gathered data from 21 childcare teachers and 255 mothers of young children attending childcare centers in Incheon. Structured questionnaires were used for collecting data from the participants. The findings are as follows: First, playfulness and social competence varied by the age and gender of the young children. Boys outperformed their female counterparts in the sub-factors of playfulness such as physical spontaneity and sense of humor. Age caused a significant difference in all sub-factors including physical spontaneity, social spontaneity, cognitive spontaneity, manifest joy and sense of humor and the social competence of young children. Second, the study examined the correlations among social competence, temperament and playfulness. A positive correlation was shown between overall social competence and activity; social competence was negatively correlated with shyness but positively correlated with the sub-variables of children's playfulness. Lastly, emotionality, shyness, physical spontaneity, cognitive spontaneity, and sense of humor were variables that had serious effects on the overall social competence of young children.

Purpose: The study is to identify a correlation among hospital nurses' emotional labor, social support and organizational commitment and to analyze the effects on organizational commitment. Methods: The participants are 300 nurses working at two general hospitals located in Gyeonggi-do, who agreed to join the study. Data collection were done from July to September in 2014. The collected data are analyzed a descriptive statistic, t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson's correlation coefficient, and multiple regression and SPSS/WIN 15.0 Program was used in the process. Results: Organizational commitment was negatively correlated with emotional works but it was positively correlated with social support. The factors affecting organizational commitment were informational support and evaluative support which were sub-domain of social support as well as level of emotional expression which was a sub-domain of emotional works, their positions and level of education. Conclusion: To increase the level of an organizational commitment, a method of coping in difficult situations and information relating to private assessments is recommended. Also, the organization should prepare a plan that members can properly manage their emotions face-to-face with clients.

A three-dimensional discrete fracture network model was developed in order to simulate the hydraulic characteristics of a granitic rock mass at Korea Atomic Energy Research Institute (KAERI) Underground Research Tunnel (KURT). The model used a three-dimensional discrete fracture network (DFN), assuming a correlation between the length and aperture of the fractures, and a trapezoid flow path in the fractures. These assumptions that previous studies have not considered could make the developed model more practical and reasonable. The geologic and hydraulic data of the fractures were obtained in the rock mass at the KURT. Then, these data were applied to the developed fracture discrete network model. The model was applied in estimating the representative elementary volume (REV), the equivalent hydraulic conductivity tensors, and the amount of groundwater inflow into the tunnel. The developed discrete fracture network model can determine the REV size for the rock mass with respect to the hydraulic behavior and estimate the groundwater flow into the tunnel at the KURT. Therefore, the assumptions that the fracture length is correlated to the fracture aperture and the flow in a fracture occurs in a trapezoid shape appear to be effective in the DFN analysis used to estimate the hydraulic behavior of the fractured rock mass.

Purpose: This study examined the relation of BMI to lipid metabolism and health promoting behavior in middle-aged women. Methods: The subjects were 113 women between 40 to 60 years of age. The data was collected from April 2003 to July 2004. BMI was measured using body composition analyzer and lipid metabolism were measured using automatic biochemical analyzer. Health promoting behavior was collected using a structured questionnaire. The SPSSWIN(10.0 version) program was used to analyze the data and get the descriptive statistics and Pearson's correlation coefficients. Results: BMI was negatively correlated with HDL-c and positively correlated with triglyceride, but there was no significance between BMI and total cholesterol. There was no significance of correlation between BMI and total health-promoting behavior. Conclusion: This study showed that BMI is meaningful in the identification of the high risk women to prevent HDL-c & triglyceride metabolism disturbance, but additional research is needed to study the correlation between BMI and health promoting behaviors in middle-aged women.

Purpose: This study investigated the relationship between knowledge and attitude about smoking of college student smokers. Methods: The data were collected from the 6th to 27th of April 2005, from 411 college student smokers in Jeollabuk-Do area. The collected data were analysed by using the SPSS WIN 11.0. Results: 1) The focus group showed mean $17.40{\pm}12.45$ in the knowledge about smoking. The knowledge about smoking was significantly different among general subject characteristics of age(F=4.84, p=.008), grade(t=2.96, p=.003), major(F=5.93, p=.001), and religion(t=2.96, p=.003). 2) The focus group showed mean $23.69{\pm}16.19$ in their attitude about smoking. The attitude about smoking was significantly different among general subject characteristics of age(F=8.15, p=.000), grade(t=-2.33, p=.020), major(F=8.35, p=.000), and residence(t=3.08, p=.010). 3) The correlations between knowledge and attitude about smoking were positively correlated(p<0.01). Conclusion: The subjects knowledge about smoking was correlated with their attitude about smoking. Therefore, we need to develop various differential smoking prevention programs and extend the role of experts.

Purpose: This study was investigated the knowledge, attitudes, and educational needs of nursing students regarding the sexuality of elderly individuals. Methods: This was a descriptive study. Data were collected from April $1^{st}$ to $22^{nd}$, 2016. One hundred ninety-three nursing students in Daejeon city and Chungcheongnam-do were surveyed. Data were analyzed using SPSS 21.0. Results: Mean scores on the knowledge, attitudes, and educational needs measures were 15.74/29, 28.45/40, and 36.67/50 respectively. There were significantly differences in major variables according to needs for sexual education of the elderly. There were also significant differences in knowledge and educational needs depending on students' age and year in school. Higher levels of knowledge of sexuality were significantly correlated with more positive attitudes and higher educational needs. Positive attitudes were also correlated with higher educational needs. Conclusion: Nursing students showed a low level of knowledge and poor attitudes towards sexuality in the elderly. This suggests that there is a need for education on the sexuality of the elderly in the nursing curriculum. This education would guide nursing students to obtain correct knowledge and positive attitudes so that they would be able to provide effective and appropriate sexuality care for elderly patients.

Refractive index and speeds of sound for the binary mixture of isomer of butanol (1) + cyclohexane, benzene and toluene (2) were measured at 308.15 K. The measured data were used to calculate deviation in refractive index ${\Delta}n$, ultrasonic speed ${\Delta}u$, isentropic compressibility $K_s^E$, available volume $V_a$, excess intermolecular free length $L_f$ and molecular association $M_A$. All the derived properties were correlated with polynomial equation. Ultrasonic speed data were predicted using various empirical correlations like Nomoto, van Dael, impedance dependence and theoretically with Schaaff's collision factor theory (CFT). Jacobson free length theory (FLT) was used to calculate $L_f$. The measured refractive index was also correlated with various mixing rules. The deviation in refractive index Δn and ultrasonic speed ${\Delta}u$ was used to determine the intermolecular interactions.

This study aims to investigate relationships between benefit sought and selection attributes of green tea consumers. For data collection, a total of 595 copies of questionnaires were collected by convenience sampling in the Seoul and Gyeonggi-do area. The data were analyzed by using SPSS 15.0. The factor analysis identified four dimensions of the benefit sought : health benefit, sensory, sociality, and self-esteem. Six dimensions of selection attributes were identified as manufacturing, design, sensory appeal, recommendation, utility and brand. The results of the canonical correlation analysis indicated that health benefit, sensory, sociality of benefit sought and manufacturing, design, sensory appeal, recommendation, utility, brand of selection attributes were highly correlated, and the self-esteem of benefit sought and recommendation of selection attribute were highly correlated. This means it is important to place an emphasis on safety production, package design, sensory characteristics, product description, utility and brand for consumers who seek health benefit, flavor and sociality. It is also important to place an emphasis on product description for consumers who pursue self-esteem benefits. Green tea marketers should consider benefit sought aspects as the most important factors affecting selection attributes on green tea purchasing.
