This study was designed to : (a) investigate the present situations of a college union foodservice and suggest authority on establishing new college foodservice, (b) estimate the service quality attributes as perceived by students, (c) identify the effecting factor to customer satisfaction, and (d) formulate the plans and marketing strategies for the increasing usage rate of the foodservice in the future. The questionnaire that developed by interviewing student were conducted with 305 male and female students, who were registered for daytime classes. A total of 284 were usable and data was analyzed by the SPSS(ver. 11.0) for the descriptive analysis, factor analysis, reliability test, multiple regression analysis, t-test, and $x^2$. The decrease in the usage rate of college foodservice by the respondents were influenced most by the 'taste of meal' and next by the 'distance'. The service quality attributes of foodservice currently under operation were evaluated above the average only for the 'price' while evaluated generally to be in the lower level of the average or under for others. As the overall level of satisfaction with the college union foodservice, most of the respondents showed the 36% for the ‘dissatisfaction’ and dissatisfied at 54.4%. Two service quality dimensions,"food . sanitation . service" and "price and comfortable environment" were derived from factor analysis and the reasons for decreasing usage rate of the college foodservice both the nearly located group from college union foodservice(NG) and the far away located group from college union foodservie(FG) indicated the ‘poor taste’ and the 'far distance', and the 'evaluation of students' dining room showed a low rating for the factor of "food . sanitation . service". "food . sanitation . service" was analyzed to have more influence to the overall customer satisfaction.

Small and medium sized enterprises' (SMEs) environmental performance and activities have been often of great concern toward sustainability as they have been playing a critically important role in the economic and industrial development. Among many initiatives to engage SMEs into the sustainability framework, Supply Chain Environmental Management (SCEM) of large companies has a great potential to persuade SMEs to adopt environmentally improved activities. This study investigated the relationship between SCEM approaches of large companies and environmental activities of SMEs in the Korean electronics industry. A postal questionnaire survey was used as a data collection method, and factor analysis and regression analysis were applied to analyse the collected data. The empirical findings suggested that SCEM approaches of large companies have positive impacts on environmental activities of SMEs. Among SCEM approaches, the collaborative approach was more effective than the arm's-length approach. Additionally, this study found positive impacts of trans-national SCEM approaches on SMEs' environmental activities.

Purpose: The purpose of this study is to find out how much influence nursing students' environmental consciousness and knowledge of medical waste have on their attitudes toward medical waste. Methods: The subjects were 211 nursing students recruited from 2 universities. Data were collected with a structured self-report questionnaire comprising measures of environmental consciousness, and knowledge of and attitude toward medical waste. Data analysis was conducted with the SPSS/WIN 25.0 program. Results: A total of 211 copies of the questionnaire were used for the final analysis, except for 9 untrusted responses out of 220 that included missing values. Those subjects' environmental consciousness who received environmental education in middle and high schools was higher (t=3.15, p=.002). The higher their grades, the better their knowledge of medical waste (F=3.40, p=.035). Those subjects' knowledge of medical waste who received medical waste education was relatively high (t=3.14, p=.002). Those subjects with clinical practice experience had more sensitive attitudes toward medical waste (t=2.06, p=.041). Those subjects' attitudes toward Medical waste who received medical waste education at the universities were relatively high (t=2.04, p=.043). The subjects' environmental consciousness was positively correlated with their attitudes toward medical waste (r=.44, p<.001). The most influential factor in their attitudes toward medical waste is their environmental attitudes and medical waste education. Conclusion: The higher the nursing students' environmental consciousness, the higher their attitudes toward medical waste. It is necessary to provide environment and medical waste education for nursing students in order to strengthen their environmental consciousness and attitude toward medical waste.

Physical activity of the people has decreased due to a sedentary lifestyle according to developing the economy throughout the world. It is thought to increase the risk of chronic diseases, including obesity, diabetes, etc. People are interested in walking, which is an easy activity to engage in as an antidote to chronic diseases. The aim of this study is to increase the diminishing physical activity of modem society by inducing walking as part of everyday life through building a walking-based activity-friendly city where people can live merrily, safely and pleasantly. For this purpose, this study conducted a satisfaction survey to dwellers of Jinhae on the physical pedestrian environments which affect determining walking participation and intentions of people, and also provided a valid model to evaluate the effects of the physical environmental factors on walking satisfaction using factor analysis and multiple linear regression analysis. The results are summarized as follows. The 18 variables of the physical pedestrian environments were selected based on pre-literature reviews. The results of the satisfaction surveys showed that the satisfaction of crossing aids in segments was highest, while the building feature was the lowest. Factor analysis was run through a two-step process. The first analysis was conducted to examine the adequacy of this factor analysis on the selected 18 variables. As a result, two variables were removed and the remaining 16 variables were extracted to the four factors by second analysis. Each factor was named function of path, effect of traffic, amenity and safety based on the each factor's commonality. Each factor score of the extracted four factors was set as the independent variable, while the overall walking satisfaction was set as the dependent variable. Then, the multiple linear regression analysis was conducted and showed that all four factors had a positive influence on the overall satisfaction of walking, especially the 'function of path' and 'amenity' factors, followed by 'effect of traffic' and 'safety'. The results of this research will be used as foundational data for creating a walking-based activity-friendly city.

Part of public arts, environmental builforms not only enhance the beauty of a building, but also serve to stabilize the citizen's psychology and as a landmark having intimate values with the city environment and symbolic meanings. Thus they do have sociocultural values as an original formative artwork. The purpose of this study was to suggest evaluation and review methods and an evaluation framework for environmental builtforms, which had legal binding under the building decoration system, to a local government to improve the quality level of urban environment. It will be such a distant goal of creating a desirable urban environment as long as environmental builtforms are merely regarded as an object to follow a vogue and a mandatory passage procedure. It's important to take a perspective of an expert to set up and suggest an evaluation system in the public aspects. In the study a consideration was made of the current systems and review criteria of environmental builtforms, which was followed by the development of a theoretical research model and of a framework for statistical evaluation by a group of experts. The questionnaire designed based on the theoretical research model was tested for validity and reliability. Its pilot test results were then analyzed to verify the hypotheses. The questionnaire collected twice were statistically analyzed in exploratory and confirmatory factor analysis with the SPSSWIN 11 program. All the analysis results were used to come up with a final evaluation framework.

The anatomical structure of the head and face are influenced by environmental factors. Therefore in this study we had undertaken to determine normal values of the head and face by 3D measurement in the 384 normal Korean male adults to find out craniofacial characteristics of Korean male adults by the age group. From the basic statistical data analysis, vertex-tragion and the length between the pupils were the longest in their twenties and grew shorter in elderly groups. According to the analysis of the craniofacial proportion, the head type of Korean male adults was short-headed. The statistically noticeable differences were found in the measurement of the left and the right sides of face in the age groups of 20, 30, 40, and 50. The results of the factor analysis of the age group showed two groups which were classified to 20, 40, 50 ages and 30, 60 ages. The order of factor analysis was as follows; the perpendicular length, the horizontal length, and the width (from highest).

The purpose of this study is to examine the health of beauty salon workers through the utilization of questionnaires concerning the extent of exposure to organic solvents found in the air of some beauty salons and any resultant symptoms in employees. The subjects were 36 employees from 10 beauty salons who agreed to participate in this study. The degree of exposure to organic solvents in the air of beauty salons was measured from September 1, 2008 to September 30, 2008. A survey of symptoms that occurred due to exposure to these solvents was also performed. The results were as follows: questionnaires were collected and analyzed from a total of 36 subjects. Of these, 28(77.8%) were female and 8(22.2%) were male. The mean age was 29.08. The mean working period was 7.13 years. Sixteen subjects attended programs at universities while 11 went to beauty schools for vocational education. When testing the concentration of organic solvents in the air of beauty salons, the highest value found was Isopropyl alcohol 511.85 ppb followed by butyl acetate, toluene, acetone, xylene, ethyl benzene, styrene, and chlorobenzene. A logistic regression analysis was performed as follows: the point of each factor was the dependent variable while sex, age, drinking, smoking, educational level, work experience, hairdresser's license, and organic solvents were the independent variables. Statistically significant difference (p<0.05) was shown in the hairdresser's license among Factor 1 and in Xylene among Factor 2; however, difference was not shown in the other variables.

In cold-formed stainless steel lipped channel-sections, web openings are becoming increasingly popular. Such openings, however, result in the sections becoming more susceptible to web crippling, especially under concentrated loads applied near the web opening. This paper presents the results of a finite element parametric study into the effect of circular web openings on the web crippling strength of cold-formed stainless steel lipped channel-sections for the interior-one-flange (IOF) loading condition. This involves a bearing load applied to the top flange of a length of member, away from the end supports. The cases of web openings located centred beneath the bearing load (i.e. beneath the bearing plate delivering the load) and offset to the bearing plate, are considered. Three grades of stainless steel are considered: duplex EN1.4462, austenitic EN1.4404 and ferretic EN1.4003. In total, 2218 finite element models were analyzed. From the results of the parametric study, strength reduction factors for load bearing capacity are determined, where these reduction factors are applied to the bearing capacity calculated for a web without openings, to take account the influence of the web openings. The strength reduction factors are first compared to equations recently proposed for cold-formed carbon steel lipped channel-sections. It is shown that for the case of the duplex grade, the strength reduction factor equations for cold-formed carbon steel are conservative but only by 2%. However, for the cases of the austentic and ferritic grades, the cold-formed carbon steel equations are around 9% conservative. New strength reduction factor equations are proposed for all three stainless steel grades.

Objectives: This study was conducted to determine firefighters' work-related accident rate and investigate the factors affecting their on-site safety. Methods: We developed a web-based self-reported questionnaire designed to inquire into firefighters' work-related accident experience and the factors (4M; Man, Machine, Media, Management) affecting firefighters' on-site safety. We distributed questionnaires to all members of firefighting organizations in South Korea by e-mail and 9,149 were returned, resulting in a response rate of 23.1%. Results: Fifteen point seven percent of the respondents reported work-related injuries within the past one year, and 35.1% answered that current accident investigation reports are not helpful for preventing the same accident from recurring. Among the 4M factors, the one most affecting firefighters' on-site safety in the order of priority is the Man factor, followed by Machine, Media, and Management. However, the results from detailed sub-categorical factors showed some differences. 'Lack of human resources', one of the Management factors, was the most influential (70.3%), followed by 'worn-out equipment' under the Machine factor (67.2%). The viewpoint of elements of the Man factor including 'forgetting instructions' and 'fatigue and illness' were significantly different according to firefighters' rank. The higher the firefighter's rank, the more they answered 'forgetting instructions,' while the opposite was the case for 'fatigue and disease'. Conclusions: The present firefighters' accident investigation report needs to be improved, and the 4M method could prove very useful. In addition, it is necessary to set up a proper firefighters' accident investigation and prevention system.
