Purpose: This study was to identify the relations between stress and health locus of control in nursing college students. Methods: A total of 243 subjects aged between 17 and 27 were selected through convenient sampling. Data were collected with a self reported questionnaire from March 2 to 25, 2013. Collected data were analyzed with SPSS/PC Win 15.0. Results: Differences in stress and health locus of control according to general characteristics were as follows. Stress were significantly different according to gender (t=-2.51, p<.05), grade (F=5.40, p<.01), school record (F=5.72, p<.01), stress solving methods (F=2.62, p<.05). Internal health locus of control was significantly different according to gender (t=2.30, p<.05), grade (F=14.73, p<.001), religion (F=4.63, p<.01), school record (F=5.29, p<.01), economic state (F=5.50, p<.001) and smoking (F=4.17, p<.05). Chance health locus of control was significantly different according to sibling rank (F=2.86, p<.05). Except chance health locus of control, internal heath locus of control and dependence health locus of control have a negative correlation with stress. 15.6% of variance in stress was explained by dependence health locus of control, chance health locus of control, and grade. Conclusion: The findings of this study may be useful in understanding the stress expression of nursing college students and developing more specific programs on personality and self-control.
This study aims to investigate whether hotel brand personality predicts restaurant loyalty mediated through trust and satisfaction. An experimental design is applied to test six hypotheses that reflect the research questions. The guests who have experienced dining in five star hotels in Seoul are targeted for sampling. A total of 184 faithful cases out of 250 cases have been analyzed. To analyze the data, descriptive statistics and multivariate analysis of variance, and structural equation modeling (SEM) are employed using the SPSS and AMOS 7. The findings indicate that hotel restaurant customers' loyalty is positively influenced by hotel brand's ruggedness and sophistication. Also, all the variables in brand personality except excitement have a positive impact on hotel restaurant customers' trust. Noticeably, hotel restaurant satisfaction is increased through brand sincerity and sophistication. Finally, both restaurant trust and satisfaction have a positive impact on restaurant loyalty. In conclusion, these findings suggest that hotel practitioners need to develop the influential variables of hotel brand personality to elevate the level of restaurant loyalty.
The purpose of this study were to define the degree of performance in health promoting lifestyle and to identify the variable related to performance in health promoting lifestyle of adolescents. The subjects of this study were 469 adolescents in the 4 high schools. The sample data were collected using a purposive sampling method from July 1 to July 27. The collected data were analysed by using descriptive statistics, Pearson's correlation coefficients, and stepwise multiple regression with SPSS PC+ program. The results of this research were as follows. First, The means of performance in the health promoting lifestyle of adolescents revealed total 2.478 ; harmonious relationships 3.045, regular diet 2.236, professional health management 1.332, sanitary life 2.910, self regulation 2.558, emotional support 2.696, healthy diet 2.408, rest and sleep 2.651, exercise and activity 2.491, self actualization 2.466, diet control 2.408. The factor with the highest degree of performance was the harmonious relationships, whereas the one with the lowest degrees was the professional health management. Second, the relationship between the degree of performance in health promoting lifestyle and its related variable were as follows. (1) Performance in the health promoting lifestyle was significantly correlated with self esteem, self efficacy, health conception, perceived health status, mother's health promoting lifestyle, mother's health conception. (2) The most important factor that affects performance in the health promoting lifestyle of adolescents was self esteem. The combination of self esteem, health conception, mother's health promoting lifestyle, self efficacy, perceived health status accounted for 45.2% of the variance in health promoting lifestyle of adolescents.
In order to identify the health promoting behavior and its related factors for high school students, a survey was performed from 4th to 8th of December 2000. Population were selected by stratified random sampling method and total 355 students replied to the self-administered questionnaire survey. Data analysis was done by descriptive statistics, t-test, ANOVA. Pearson's Correlation, stepwise multiple regression. The results were as follows: 1. The average score of health promoting behavior practices was 2.23(SD=.41) points by the 4 point scale, which was lower than that of adults. In the subcategories, the highest degree of performance was self-actualization (mean= 2.68, SD=.68), and the lowest degree was health responsibility (mean = 1.33, SD= .41). 2. According to gender(t=2.70, p=.00), school type(t=2.53, p=.01), father's educational level(F=4.16, p=.00), sleeping hours(F=3.80, p = .02), and number of hours at school (F=4.44, p=.01), there were a statistically significant differences in modifying factors. of health promoting behavior. 3. Health promoting behavior showed significant positive correlations with self- efficacy(r= .461. p= .000), internal health locus of control (r=.284, p=.000), perceived health status (r=.163, p=.002). 4. The combination of self-efficacy, internal health locus of control. school type, and gender explained 30% of the variance of health promoting behavior. Therefore, the findings of research can serve as the basis for developing health promoting programs, which enhance self-efficacy and performed in school and community.

In this paper, velocity measurement of fast moving object for traffic information acquisition using line sampling of image is proposed. Velocity measurement for traffic information acquisition of moving object is that the first sample line and second sample line on the road is set, then car is detected by using difference image method between time-variance hue data of image when car is passing two sample lines and hue data of the reference image, and velocity of the car is measured by using frame number of video which is occupied by two sample lines. Identification of the car is performed by hue of the detected car between the first sample line and second sample line, respectively To examine the propriety of the proposed algorithm, identification and velocity measurement for driving car is evaluated. The evaluated results is that it is identified by hue data of car passing two sample lines, and the velocity measurement for driving car is less than 3% comparing with X-band speed gun.

Purpose: This study was done to identify the relationship of malnutrition, social network and health-related quality of life and to investigate the main factors influencing health-related quality of life in elders. Methods: The research design was a descriptive survey design using a convenience sampling. Data were collected by self-report questionnaires from 196 elders. Data analysis was done using SPSS 18.0 pc+ program for descriptive statistics, Pearson correlation coefficients and stepwise multiple regression. Results: The average score for health related quality of life was 3.33 (SD=0.86). Differences in health-related quality of life were statistically significant according to age, gender, occupation, presence of spouse, monthly income, source of income, economic status, medicine, and existence of chronic disease. Health-related quality of life was significantly correlated with malnutrition and social network. Major factors affecting health related quality of life for elders were malnutrition, occupation, age, social network, and economic status which explained 52.0% of the variance in health related quality of life. Conclusion: Findings provide a basis for developing nursing interventions to improve health-related quality of life. Future studies are needed a wide variety of variables that might influence health -related quality of life in elders.
In this study, thirty-two stands in Kwangnung forest located in the central part of Korea were preferentially selected. In each stand, all stems for trees and shrubs were recorded by species and their girths were measured down to 5cm. In addition, several enviromental factors such as field soil pH, field soil moisture, soil compressibility, depth of soil, thickness of litter layer, elevation and basal area were measured. Three soil cores were sampled and various physical and chemcial properties was determined. The vegetational data were subjected to three kinds of multivariate ordination(PO, PCA, RA). The results suggested that Kwangnung forest was consisted of three forest types: coniferous, mixed and broad leaved forest communities. The relation between the stand scores of ordination and several environmental factors were investigated in terms of correlation analysis in order to examine the relationships between the vegetation and certain environmental factors. As a result of this analysis, the amount of sand content in A1 horizon decreased frm the coniferous to broad leaved forest, while maximum field capacity, pore space, exchangeable cations, loss on ignition, soil pH nad the amount of total nitrogen had a tendancy to increase significantly. However, easily soluble phosphorus appeared to have little to do with the forest types. The result of species ordination of centered-standardized PCA suggested that the major successional pathway in Kwangnung forest was; Pinus densifloralongrightarrowQuercus mongolica, Q. serrata, Q. alienalongrightarrowCarpinus laxifloralongrightarrowC. erosa in sequence. This trend is in good agreement with the past studies. In three kinds of ordination (centered PCA, centered-standardized PCA and RA) based on nineteen species and twenty-five stands, the total variances accounted for the first three axes were 77%, 46% and 63% respectively. The estimated beta diversity in Kwangnung forest assumed as a coenocline, was 1.5~1.8 HC. Increasing the effect of the sampling errors on ordination perfermance, this low heterogeneity seems to cause the poor concentration of the total variance. The results from the four kinds of ordination were in good agreement with each other, especially between PO, centered-standardized PCA and RA appeared robust. It seems to be worthy of applying multivariate method for analyzing other forest communities in Korea.
Water and soil properties in paddy fields subjected to organic and conventional farming were characterized over the rice cycle in South Korea. To achieve the goals of this study, we sampled and analyzed soil and water from 24 organic paddy plots and 11 conventional paddy plots in March, May, August, and October 2016. The results were analyzed using statistical analyses, including analysis of variance (ANOVA), cluster analysis, and principal component analysis. The ANOVA results showed that water content (WC), electrical conductivity (EC), organic matter (OM), and available phosphorus ($P_2O_5$) in soil varied significantly (p < 0.01) depending on the farming method. Higher OM, EC, and $P_2O_5$ of soil were observed in the conventional paddies than in the organic paddies. All soil properties, except pH and ammonium, depended on seasonal variation. Cluster analysis revealed that soil properties in May were distinctly separated from those in other seasons mainly due to basal fertilization. The principal component analysis distinguished the soil properties in different seasons, but such a distinction was not observed between the soil properties in organic and conventional paddies. Low contents of WC, OM, and total N were observed in March. High concentrations of nitrate and total P were observed in May, but these were low in August and October. The soils from October were also characterized by high concentrations of EC and $P_2O_5$. These results indicate that the sampling time for soil and water can significantly influence the evaluation of soil properties with different farming methods.

Purpose: The purpose of this study was to explore self-directed learning ability and its affecting factors among undergraduate students. Methods: A descriptive cross-sectional study design was used. Using a convenience sampling method, data were collected from 196 undergraduate students enrolled in one national university. Negative psychological tendency (i.e. Type D personality), academic engagement, and self-directed learning ability were assessed using a structured questionnaire. Data were analyzed by descriptive statistics, t-test, and analysis of covariance, Pearson's correlation coefficients, and stepwise multiple linear regression, using SPSS/WIN 23.0 program. Results: The mean age of the students was $21.61{\pm}2.40years$ and 56.6% were male students. Approximately, one third (n=67, 34.2%) of the students had Type D personality. The average scores of academic engagement and self-directed learning ability were $3.01{\pm}1.14$ and $3.46{\pm}0.50$, respectively. After controlling for sociodemographic variables, the Type D personality and academic engagement were significant predictors of self-directed learning ability (${\beta}=.64$, p<.001; ${\beta}=-.13$, p=.021, respectively). This model explained 53.6% of the variance in self-directed learning ability. Conclusion: The study identified that Type D personality and academic engagement affect self-directed learning ability of undergraduate students, one in a negative way, the other in a positive way. Educators and educational policy makers need to make efforts to include interventions and strategies that increase academic engagement and change negative psychological dispositions such as D-type personality in the undergraduate education curriculum.
Purpose: This study provides preliminary data for job satisfaction and organizational commitment by finding out the effects of ethical climate perceived by and ethical sensitivity of nurses on the organizational effectiveness of small and medium-sized hospitals. Methods: Study participants were 155 nurses who had worked one year or longer at small and medium-sized hospitals located in the G city, and they were recruited through convenient sampling. The SPSS/Win 20.0 program was used analyze frequency, percentage, average, standard deviation through independent t-test, one way ANOVA, Pearson's correlation coefficient, and multiple regression. Results: The mean score for organizational effectiveness of nurses had a significant positive correlation with ethical climate and ethical sensitivity. ethical climate, experience of receiving nursing ethics education were the major predictors of organizational effectiveness and explained 61%(F=48.36, p<.001) of the total variance in the study. Conclusion: it has been confirmed that ethical climate and experience of receiving nursing ethics education affect organizational effectiveness, a concept that shows the degree of achieving organizational goals while nurses at small and medium-sized hospitals.
