The purpose of this study was to analyze the usage characteristics and the role of spatial and social psychology of open spaces in urban neighborhoods. The survey for this study was conducted on 318 residents in Gyungsan. For analysis, the frequencies and means were calculated, the chi-square test, t-test, and analysis of variance were performed. Survey results revealed that, first, not only the preferred open space type but also the usage characteristics by gender were different. The tendency for males was to visit open spaces to exercise and to stay for longer than one hour. However, the females visited open spaces to care for their children and meet friends or neighbors. They also visited more often than males but stayed for a shorter time. Second, females tended to consider the open space as a place for rest and leisure. Females valued the social psychology aspects of the open space function. Third, regarding the spacial role of open space in urban neighborhoods, study participants believed that the waterside parks improve the quality of life, but were concerned for the safety of children. Considering the social psychology role of open spaces, study participants regarded the waterside parks as improving emotional health. Particularly, they believed the waterside parks played a greater role in daily life as a place for meeting, resting, and leisure than other open space types such as playground, children's parks, and sport parks.

In this paper, we suggest a usage profiles for electric home appliances. In Korea, it is published the records for total consumption of electricity in a house but the electric home appliance consumption records in a households are not. To build the data, we must collect the usage of every appliances in a house and the information of the household which live in the house. Unfortunately, it is hard to get the data because of the worry about the breach of privacy. In this paper, we make a scenarios on the electricity consumption pattern of a few households type. Based on the conjecture, we make the power consumption profiles for some home appliances. Comparison to the total electric consumption records for a house, we found our scenarios are quite reasonable.

Rural Korea has been becoming heavily aged societies from the end of 20th century due to the massive depopulation of young generation and extension of the average span of human beings. Although rural communities in Korea had been traditionally based on closely webbed social relations, almost all of community self-help organizations disappeared in recent time with very strong urbanization trend. However, almost all rural villages in Korea have the village seniors' union -'NO-IN-HOE' in Korean speaking- of which members usually use, operate and maintain community facilities in terms of voluntary base. Using these facilities, most of public/common/private services and community activities have been being served or provided. So, the purpose of this study is to investigate the usage tendency of community facilities and needs of the rural elderly and to propose the improvement strategies for their optimum usage. For this purpose, data was gathered both from community (107 villages) and individual level surveys(881 older people). The statistical method used for data analysis was descriptive statistics. The major findings were as follows : It was found that the dominant family type of the rural elderly was elderly-only household (75%) with very limited economic capability. There are 2$\sim$3 common community facilities with village including the seniors' center -'KYOUNG-RO-DANG' in Korean speaking. Many of the elderly (74%) use the center once or twice per week. There are several rooms in the center, like as kitchen bathroom and health room, of which usage frequency differs respectively. Many rural elderly want assistance from out-of-village for good maintenance and free use of these facilities.

Purpose: According to the growth of technology in the service industry, the interaction service between customer and employee has recently been transformed into between customer and technology by Self Service Technology (SST) requiring direct interaction with customers. In this context, self service technology such as unmanned ordering system installed at the store is actively introduced at the work place to reduce labor costs by food and retail company and the research for self-service technology which is rapidly replacing existing face-to-face service is needed. As the growth speed of SST is rapid, many researchers have studied the characteristics of SST, in every sector of business worldwide. Among the characteristics, attributes, Self Service Technology Quality (SSTQUAL) to evaluate SST is important because it may cause the customer's behavior. Thus, this research focuses on the effects of SSTQUAL on SST Satisfaction and SST continuance usage intention. This research suggests the guidelines for how Restaurant Company should prepare SST and build their customer satisfaction and continuance usage that increase the sales. Research design, data and methodology: This study tests the structural relationship between SSTQUAL of unmanned ordering system, SST satisfaction and SST continuance usage. SSTQUAL divided into four sub-dimensions and two categories, cognitive service attributes (Convenience, Functionality) and affective service attributes (Enjoyment, Assurance). In order to achieve the purposes of this research, research model and hypotheses were developed based on previous researches. All constructs were measured with multiple items developed and tested in the previous studies. The data were collected from 524 customers experiencing SST and were analyzed through SPSS 25.0 and SmartPLS 3.0 statistical package program. Results: The findings of this research are as follows. First, all SSTQUAL have significant positive impacts on SST satisfaction. Second, SST satisfaction has significant positive impact on SST continuance intention. Third, cognitive service attributes and affective service attributes had wealth of explanation of service attribute more than a single dimension. Conclusions: The implications of this study are as follows. Overall, Restaurant Company should manage SSTQUAL consisting of not only cognitive service attributes (Convenience, Functionality) but also affective service attributes (Enjoyment, Assurance) to satisfy customers basically regardless of the type of restaurant.

There are 4 types of equipment in diagnostic radiography. These are single phase, three phase, inverter type and condenser type X-ray generators. It is very confusing to make an adequate exposure factor and to know the usage of different type of X-ray generators. In this experiment, I explored a comparative study of outputs in 4 different type of X-ray units. I expect that this experiment could be helpful for manufacturer to make both the X-ray equipment better, In terms of Ideal exposure factors, thereby reducing the patient dose. Experimental results are as follow : 1) X-ray output The ratio of X-ray output of single, three phase and inverter type of X-ray generator was 1 : 1.6 : 2 without absorber and 1 : 2 : 2.6 with 20 mm aluminium absorber. 2) Beam quality The X-ray beam quality of single phase generator was proved to be softer than three phase and inverter type of generators by 0.4 mmAL and 0.55 mmAl HVL respectively. 3) Reproducibility Linearity of X-ray output Retroducibility of X-ray output met the regulation below CV 0.05 and linearity also met the regulation below 0.1 in 4 types of diagnostic X-ray generators. 4) The comparison of incident dose Three phase X-ray generator was 20% higher than two other X-ray generators in radiation dose to make same film density.

This reserch categorizes the workplace recipient into selection criteria and studies the difference of demographic characteristics, counseling usage characteristics, job burnout, and differentiation of counseling behavior according to the subtype criteria. The survey has been collected 398 employee's responses who have no experience in counseling, who belong to the companies deploying counseling program and the companies are located in Seoul and Kyunggi area. As a result of the cluster analysis, the group was divided into "People-Product Oriented Type", "People-Product-Place Oriented Type", "People-Product-Process of service assembly Oriented Type". Subtype differentiates demographic characteristic and counseling usage characteristic and it convinces that junior employees belong to "People-Product Oriented Type" and senior employees belong to "People-Product-Place Oriented Type" and "People-Product-Process of service assembly Oriented Type". "People-Product-Process of service assembly Oriented Type" is the cluster who takes counseling services most likely if the counseling requirements are raised. Each subtype shows the differentiation of job burnout and "People-Product Oriented Type" is more exposed in job burnout among the subtypes which required urgent counseling assistance. This research is meaningful to take differentiated marketing strategies in subtype basis by considering workplace counseling service selection and recipient characteristics. Furthermore, it discusses the meaning of this research and the proposal for the further investigation.

The purpose of this research is classifying stream into different types depending on various factor from the perspective of stream corridor restoration and using it as basic data, which are used to consider efficient management and planning for the healthy stream according to the characteristic by types. In this study, 130 points of location of the Nakdong river basin which consist of various geographic factors have been chosen and hierarchical cluster analysis has been carried out in these points by using biological and physiochemical factors whose health can be considered to be predicted and evaluated. As a result of cluster analysis, there were three divided types. Type A whose biology and water quality are considered the best was the highest in forest area percentage so that it was classified into natural stream. Type B was classified into a rural region stream with a mixture of urban and agricultural region. Type C, with the most damaged water quality and biology health had the most urban region surface area and was named as urban region stream. Moreover, an overall restoration strategy according to characteristic by stream types was set. By the results of correlation analysis on factors, water quality showed a high correlation with biological properties and was affected by surrounding land usage. In evaluation of streams, it proves the need to consider not only other habitat's geographical and biological factors but also the water quality and land usage factors. There needs to be further research on stream ecosystem functionality factors and structural aspects by using a more objective and total evaluation result in selecting additional index and various other specific classification methods by stream types and its restoration strategies.

The purpose of this study was to compare the usage of beef and foodservice managers' perceptions of beef quality by foodservice type. A survey was conducted on 546 dietitians, and 499 acceptable responses were used for data analysis. By weight, pork was the most used meat in foodservice institutions, followed by poultry and beef. More than half of the foodservices selected meat suppliers by competitive bidding. Approximately 85.8% of the respondents used Hanwoo beef, followed by Australian beef and Youku beef. Beef type differed significantly by foodservice type (P<0.001): most of the schools and social welfare facilities used Hanwoo beef, whereas most hospitals and business/industry operations used Australian beef. When purchasing beef, safety of beef was rated the most important, while eco-friendliness was rated the least important. Most of the dietitians understood that marbling is one of the determinants of the beef quality, but were not aware of other components. Dietitians that selected Hanwoo and Youku beef were more satisfied with quality, taste, nutrition, freshness, country of origin, package, customer, preference, and availability for various menus than those who used imported beef. Dietitians who used Hanwoo beef were the most satisfied with country of origin, whereas the others were the most satisfied with safety. Since the dietitians are in charge of planning menus and selecting meat suppliers at foodservice institutions, they should make knowledgeable decisions by understanding meat supply systems and quality of beef.
