The primary purpose of this paper is to prove a clear relationship among land use type, vegetation level and surface temperature. For this purpose, this paper presents series of spatial distribution maps of the three features obtained through the visual interpretation of digital images. The result of study tells us that the spatial distribution of the vegetation level is very similar with that of surface temperature. By analyzing the relationship between surface temperature and land use types, this study categorizes the eighteen urban land uses into 7-8 groups according to their average surface temperature. The Duncan test was conducted to categorize the land uses. The surface temperature of manufacturing related land use is the highest, semi-residential use is the next, non-residential land use is the next to the lowest, and the agricultural and forest land use is the lowest. This paper provides another strong evidence of the relationship by showing the regression result.

The purpose of this study was to develop the better fitting and more comfortable sleeve pattern for women's jacket, as the first step. Five types of existent sleeve pattern were collected, made and worn compared with the sensory evaluations method. The main results of this study were as follows 1. Sensory evaluation for appearance; According to the result of Duncan's multiple range test among the five sleeve patterns, TOJAIUN method sleeve was most satisfactory, and the next was the JUNGMYUNGJA method sleeve followed by NASAN, MOONWHA, ESMOD method sleeve. 2. Sensory evaluation for comfort; The result of Duncan's multiple range test showed that the ESMOD method sleeve was comfortable, and the next was the Japanese MOONWHA method sleeve followd by JUNGMYUNGJA, TOJAIVN, NASAN method sleeve. The result of 3-way ANOVA, main effect for 3 independent variables and interaction for pattern x part, posturers part showed significant difference.

The purpose of this study was to analyze the water quality change when wastewater applied to study paddy fields. CREAMS-PADDY (Chemical, Runoff and Erosion from Agricultural Management System) model was used to estimate the field-scale water quality. Simulated results were compared with observed data monitored from Byeongjeom study paddy fields which is located near the Suwon sewage treatment plant in Gyeonggi-do. Significance analysis was performed for the three different irrigation water quality level and five fertilizer reduction scenarios using LSD (Least Significant Difference) and DMRT (Duncan's Multiple Range Test). Total nitrogen was found to be significant for both irrigation water quality level and fertilizer reduction while total phosphorus was not. Annual drainage load for total nitrogen was reduced by 66~92 % compared to irrigation load when treated wastewater irrigated to study paddy fields from 2002 to 2007. Total phosphorus was reduced by 70~86 %.

This study explored the instrumental values of homemakers by object family living and other social living. Homemakers' instrumental values on family living were compared with those on other social living. Through this it make to explain differences in instrumental values on 2 objects. 650 homemakers were adapted as data. The data were analyzed by frequency percentage means one-way ANOVA duncan-test and paired T-test The results showed significant differences in instrumental values by objects.

The number of calling ports has been decreased and the degree of inter- and intra-port competition has been increased, which is caused by the market trends that shipping liners have and operate their own terminals, strategic M & A frequency occurs among shipping liners, and container vessel size is increasing. The trends also cause shipping liners to change the evaluation factors for decision to call a particular port such as port preference, potential for growth, port competitiveness, etc. Since the decision of liners greatly influences the policies for port and terminal development, it is worth having interest in the evaluation factors. Therefore, this work intended to evaluate 8 major ports (Port of Singapore, Hong Kong, Shanghai, Busan, Rotterdam, Kaoshing, and Tokyo) with regard to liners' evaluation factors (calling port preference, potential for growth and port competitiveness) and to classify ports by similarity of evaluation factors with the methodologies of ANOVA analysis and Duncan test. The result shows implication for liners' viewpoint to evaluate major ports in the world.

This study is a convergence study of 596 high school girls in order to confirm the relationship between the desired number of meat side dishes and preference of fish side dishes in school meals. Data were analyzed by χ²-test, ANOVA-test, and Duncan's test using SPSS 22.0 program. The results of the study were as follows. The scores of the subjects for promoting palatability were highest in the items 'Easy to eat' and 'Without fishy'. The scores of 'Nutrition Education', 'Combined with Preferred Food', 'Without Fishy' and 'Add Preferred Flavor' tended to increase significantly as the desired frequency of meat side dishes increased from 'less than three times a month' to 'more than five times a week'. The findings of the study confirmed the relationship between the desired frequency of meat side dishes and preference of fish side dishes. Therefore, this study is expected to provide high school girls with a way to increase fish preference.

In this paper the forming simulations of ellipse bulge have been researched by using $PAM-STAMP_{TM}$ to estimate the sheet metal forming and the plastic deformation characteristic of ellipse bulge. Thin elliptical diaphragms of brass, copper, aluminum, and mild steel are bulged in elliptical dies having aspect ratios of 1.33 and 2. In order to compare the simulation results with the experiment and ellipse bulge's theory derived by using Johnson and Duncan's theory, the relations of hydraulic pressure and polar height, polar thickness strain and polar height, were compared. According to this study, the results of simulation and ellipse bulge's theory derived by using Johnson and Duncan's theory, and the bursting pressure and the bursting polar height are good agreement to the experiment. So, the results of simulation by using $PAM-STAMP_{TM}$ and the ellipse bulge's theory will give engineers good information to make assessment the formability and plastic deformation characteristic of hydraulic ellipse bulge test.

The purpose of this study is to study real body size and ideal body shape by considering the degree of satisfaction of body part and understanding body size by the degree of leanness/obesity. The subjects in this study were 420 males from 18 to 25 years old. Body measurements and surveys were taken and analyzed by mean, standard variation, correlation analysis, regression analysis, crosstabulation analysis, cluster analysis, one-way ANOVA, and Duncan's Test. The results of analyses indicate that the subjects tended to be satisfied with thick chest and upper limbs, wide shoulder width, and preferred to be tall and have big hands and feet. By cluster analysis of 19 variables, the subjects were divided into 4 groups, each consisting 41, 138, 134, and 47 males. Because the 19 variables were body measurements transformed to eliminate the body size factor, this classification was considered to express how lean or how obese a human body appears. The results of one way ANOVA and Duncan's Test indicate that, according to the degree of leanness/obesity from Group I (lean tendency) to Group IV(obese tendency), characteristics of the body shape changed as follows; height became lower, limbs became shorter, trunk and limbs became thicker and weight became heavier. Also it showed that Group IV were most satisfied with chest girth, upper limb girth and shoulder width and Group I with height, hip girth and waist girth.
