This research has acquired preliminary information about the existing conditions and understanding of members regarding time management for members in the architectural field. The goal of this research is to construct a basis for the time management education framework in architectural field in the future. This research mainly focuses on following questions based on limited objectives: Do groups of academics and professionals have understanding and knowledge of time management? Can the level of an individual's scheduling techniques be correlated to the patterns of knowledge and understanding of time management principles and practices? Can the time management practice status in individual's working environment be correlated to the patterns of knowledge and understanding of time management principles and practices? Can an individual's self-confidence level be correlated to the patterns of knowledge and understanding of time management principles and practices? Data have been collected through comprehensive questionnaires given to academics and professionals in United States. By means of statistical analysis, the hidden patterns, deficiencies and relationships in attitudes about time management have been revealed. The statistical analysis has produced conclusions that, among several subdivisions, self-discipline and planning have strong relationships and confidence, personal organization, control, and information gathering subdivisions have certain relationships with objectives of time management education in this research.

Purpose : The aim of this study was to investigate the influences of personality traits on depression and quality of life of stroke outpatients receiving rehabilitation therapy. Methods : The current study included 52 outpatients who received occupational therapy in a rehabilitative and general hospital located in Incheon. Their personality traits were assessed using the Big Five Inventory-Korean Version (BFI-K), and depression was measured using the Beck Depression Inventory (BDI). Quality of life was evaluated using the Stroke Specific Quality of Life (SS-QOL) scale. The collected data were analyzed to identify the effects of personality traits on depression and quality of life using a multiple regression analysis. Result : Neuroticism and depression were significantly correlated (p<.05), and neuroticism and agreeableness were significantly correlated with quality of life (p<.05). Additionally, depression and quality of life were significantly correlated (p<.05). Neuroticism affected depression significantly ($R^2=.503$, p<.05). Among the five personality traits, neuroticism, agreeableness, and extraversion had a significant effect on quality of life ($R^2=.474$, p<.05). Conclusion : These findings suggest that personality traits need to be considered in order to improve the quality of life of stroke patients.

Cicada is a very familiar insect to people but habitat characteristics of them are not well known. To investigate habitat characteristics of cicada nymph, plant species, plant cover, soil hardness, accumulated organic mass, organic content in soil, and root density were investigated at 11 sites in an apartment complex garden in Seoul. Selected sites had different densities of cicada nymph case above the ground. Density of cicada nymph case was positively correlated with accumulated organic mass, organic content in soil, and root density and negatively correlated with soil hardness. Even though shrub coverage was not linearly correlated with the density of cicada nymph case, 80% cover of shrub was necessary for the high density of them. Data in this study suggested that organic matter in addition to root density be the primary limitation factor of cicada nymph and high amount of litter-fall decrease soil hardness through the increase of soil organic matter. This study suggests that the density of cicada nymph can be managed through organic content in soil.

We patterned water quality of agricultural reservoirs according to the differences of six physico-chemical environmental factors (TN, TP, DO, BOD, COD, and SS) using four different ordination methods: Principal Components Analysis (PCA), Detrended Correspondence Analysis (DCA), Nonmetric Multidimensional Scaling (NMS), and Isometric Feature Mapping (Isomap). The data set was obtained from the water quality monitoring networks operated by the Ministry of Agriculture and Forestry and the Ministry of Environments. Chlorophyll-${\alpha}$ displayed the highest correlation with COD, followed by TP, BOD, SS, and TN (p<0.01), while negatively correlated with altitude and bank height of the reservoirs (p<0.01). Although four different ordination methods similarly patterned the reservoirs according to the gradient of nutrient concentration, PCA and NMS appeared to be the most efficient methods to pattern water quality of reservoirs based on the explanation power. Considering variable scores in the ordination map, the concentration of nutrients was positively correlated with Chl-${\alpha}$, while negatively correlated with altitude and bank height. These ordination methods may help to pattern agricultural reservoirs according to their water quality characteristics.

Purpose: The purpose of this study was to identify whether neck circumference might be correlated with other obesity indices and to determine the neck circumference cutoff level for obesity in female college students. Method: The data were obtained by measuring other anthropometric indices including BMI and neck circumference from 325 female college students in J city, Chungbuk Province. Receiver Operating Characteristic curve(ROC curve) analysis was used to find the optimal neck circumference cutoff level against BMI $25kg/m^2$. Results: The mean BMI was $21.4kg/m^2$, and the prevalence of obesity was 12.6%. Neck circumference was significantly correlated with body weight, BMI, waist circumference, hip circumference, waist to hip ratio, % body fat, triceps skinfold thickness, systolic and diastolic blood pressure. Neck circumference of 31.95cm was the best cutoff level for determining female students with a BMI over $25kg/m^2$, and the characteristic was acceptable with 97.6% sensitivity and 85.6% specificity. Conclusions: Neck circumference was strongly correlated with the other conventional obesity indices. Female college students with neck circumference over 31.95cm require an additional evaluation of obesity.

The purpose of this study was to analyze the correlation between the effluent of the sewage treatment plant (STP) and the adjacent stream located downstream of the STP in Nakdong River. The flow and water quality such as BOD, COD, SS, T-N, and T-P data for 12 STPs and adjacent downstream monitoring stations in the main stream and tributaries of Nakdong River were collected from 2012 to 2015. As a result of correlation analysis between river flow and water quality at the river water quality measurement point, COD, SS and T-P were correlated positively with river flow rate at 6, 8, and 6 points, respectively. As a result of analyzing the water quality of sewage treatment plant effluent and downstream stream, BOD and COD were correlated at 2 and 3 points, respectively. T-N showed a positive correlation at 9 points, and 7 of them had a strong positive correlation, indicating that sewage treatment effluent had a large effect on downstream streams. In this study, we found that the correlation between river flow rate and water quality factors (COD, SS, TP) was high for river water measurement points, and the sewage treatment plant effluent was correlated with the T-N value of adjacent streams.

Purpose: The purpose of this study was to identify the influencing factors on burnout after analyzing the relationship among clinical nurses' various perfectionism and coping styles. Methods: A descriptive, cross-sectional study was conducted with 200 clinical nurses who had six months or more years of clinical experiences from two general hospitals located in D city. The data were analyzed by t-test, one-way ANOVA, Pearson's correlation coefficients, and stepwise regression analysis using IBM SPSS statistics 23.0 program. Results: The burnout of clinical nurses was positively correlated with socially prescribed perfectionism and negatively correlated with active coping style. Socially prescribed perfectionism was positively correlated with active coping style and passive coping style. Influencing factors on the burnout of clinical nurses were socially prescribed perfectionism (${\beta}=.37$), satisfied work unit (${\beta}=-.64$) and neutral satisfaction of work unit (${\beta}=-.27$), over 40 years of age (${\beta}=-.21$), and active coping style (${\beta}=-.14$). The model consisting of these variables explained 42% of variance of burnout in clinical nurses. Conclusion: Based on the findings of this study developing intervention programs that consider influencing factors such as perfectionism and coping styles is needed to reduce the level of burnout of clinical nurses.

Adolescence is vulnerable to various Health Risk Behaviors (HRB). These behaviors can affect his remaining life as well as adolescence, thus prevention of HRB is a critical issue in health education. This study is aimed to provide basic information for prevention of HRB. Thus, this study was conducted to analyze the impact of peer group's health risk behaviors on health risk perception (HRP) and that of health risk perception on health risk behaviors based on 832 respondents. The 852 subjects were selected in six middle and high schools in Seoul through random sampling. Data were collected from September, 18-October, 21, 1998, and the 832 data were analyzed after excluding the 20 incomplete and inaccurate data. Questionnaire items and measures are based on an instrument to measure Perceived Health Risk Perception, which Hodge B.C. developed in 1992. Cronbach alpha is used to test the reliability. The reliability of HRP and HRB is 0.9473, 0.8768 in this study, Statistical analysis divided into four phases. First, the impact of socio-demographic characteristics on HRP is analyzed by oneway ANOV A. Male students have lower HRP than female students. As grade goes up, HRP is getting lower. Perceived higher concern of parents and HRP are correlated. And the experience of school health education and HRP are correlated. Second, the impact of peer group's HRB on the HRP is analyzed by linear regression. Peer group's HRB and HRP are negatively correlated, Third, the impact of HRP on HRB is analyzed by linear regression. There is a correlation between high HRP and low HRB. Fourth, Powerful impact factors on HRB are analyzed by stepwise multiple regression. Grade, gender, peer group's HRB, and related HRP is entered as independent variables. Because of correlation between entered variables, three interaction variables between grade, gender, peer group's HRB and related HRP also entered, In general, peer group's HRB is the most accountable factor to HRB. And Interaction variable between HRP and peer group's HRB and HRB are negatively correlated. These results indicate that HRP may reduce the impact of peer group's HRB on HRB. Some recommendations are as follows: First, health educational programs suitable for gender and grade are required. Second, a systematic cooperation between school and home is necessary for effective prevention of HRB. Third, the educational effect for decreasing HRB by increasing HRP is statistically assisted. However, peer group has much stronger impact on HRB than subjective HRP, thus special consideration and management are necessary for peer group which does HRB more frequently.
