Recently, developing U-City as an integrated set of ubiquitous spaces has been regarded as a promising field in realizing ubiquitous computing technology. However, well-organized requirement analyses of U-City to declare what kinds of ubiquitous space services are needed and which ubiquitous computing technology should be incorporated to come up with the needs are still insufficient. Hence, the aims of this Paper are to Propose a set of unique U-City construction philosophies and to analyze which services Should be offered in the ubiquitous Space services in U-Cities. A field survey to the citizens who are potential end users of the ubiquitous space services was conducted to analyze the success factors of U-City using CSF methodology. Focused group interview with professionals in the field of ubiquitous computing technology in Korea was then performed to identify the relationship of the ubiquitous space services and the critical success factors.

One of the main objectives of this paper is to provide insight to understand the effect of natural disasters on local government finance. That is, to analyze local governments' sales tax revenues after Hurricane Ike. Three Texas cities are examined: League City, Pearland, and Sugarland. Based on data collected from the Texas Comptroller's Office and the US Census, we found local governments experience a short-term increase in sales tax revenues and a long-term decline after the hurricane strike the region. On average, a major hurricane has a two-year impact on local government economy. The findings are essential for practitioners because in order to have a prosperous recovery after natural disasters, public managers have to prepare financially for short term changes in their sales tax revenues.

In the Korean Economically Active Population Survey(EAPS), the sample sizes for small areas are typically too small to provide reliable estimators because the EAPS has been designed to produce unemployment statistics for large areas such as Metropolitan Cities and Province. In this study, we consider the synthetic and composite estimators for the unemployment rate of small areas, and apply them to real data on Choongbook province which is from the Korean EAPS of December 2000. The mean square errors of these estimators were estimated by the Jackknife method, and the efficiencies of small area estimators were evaluated in terms of the relative standard errors and the relative root mean square errors. As a result, the composite estimator is much more efficient than other estimators and it turns out that the composite estimator can produce the reliable estimates of the unemployment rate of small areas under the current EAPS system.

This study was conducted to evaluate the methods used in nursing procedures for infection control. Skilled nursing procedures are related to prevention of hospital infection. The sample consisted of 301 nurses’ response to the questionnaire. Data were collected from Feb. to March, 1993 from 35 hospitals located in five major cities. The findings of the study are as follows : 1) Rotatively unsafe nursing procedures were reported for preperation of IV therapy, change of IV site and aseptic dressing on IV site, hand wash-ing and use of paper towels, use of sterile urine bottle with indwelling urinary catheter, management of dressing cart, disinfection of transfer forcep, ambu respirator, laryngoscope, humidifier and handling of incubator. 2) Relatively safe nursing procedures were reported for management of suction tube, marking for contaminated materials and waste collection. The rate of participation in education programs for infection control by the nurses was higher than in other research results. 3) Further study on procedures for IV site in-fusion and care of dressing cart are recommended.

The purpose of the study is to researdch clothing consumer behavior of men and women over age of 20 years and to find out the reasonable maximum utility on clothing behavior. The factors are eight distinguished parts such as sex, age, monthly income, occupation, floor space, number of room, number of family and place of residence. A common questionaire is introduced to survey the clothing consumption activity and the home background. Sources to measure them are gathered in the whole country including major cities. The questionaire of 915 correspondents of 368 males and 547 females is investigated for this research. Some of the data are analyzed by correlation, frequency, percentage, mean, and S.D. Others are investigated by ANOVA Test, x2-Test, and Multiple Range Test. The results from the survey are as followings: 1. Only four factors such as sex, monthly income, occupation, and floor space have a significance in the clothing consumption activity. 2. This survey reveals that many cloths have been kept in dead storage and concerns of utility have risen high. 3. This survey has shown that the correspondents have deep concerns about using colthing exchange store, clothing lending store, and trunk room to utilize dead storage clothing efficiently.

Based on the investigation results on the damages of some underground structures due to the severe Kobe Earthquake it concludes that the aseismicity of underground is far superior to that of aboveground structures. Therefore, at first, necessity to reconstruct strong cities especially by good use of underground space will be discussed. Then two non-circular shield-tunneling projects in Japan are discussed. The first is construction of the world's first shield driven double track subway tunnel of rectangular shape for the Kyoto Municipal Subway. This paper presents a report on the overall planning, the tests that were performed in the process of planning, and the results of driving. The second is the design of the Hirakata Tunnel, with three traffic lanes and shoulders on one side, which will be constructed as one of the tunnels for The New Meishin (Nagoya-Kobe) Expressways. This paper presents the feasibility study of the shield tunneling method, using the same design criteria as the non-circular, horseshoe section of mountain tunnel, to the equivalent section of the Hirakata Tunnel.

After Industrial Revolution, the rapid economic development and changes in industrial structures caused the urban centralization phenomenon of population, and the consequential and swift urban development forced to require somewhat more of necessary residential lands. With deferring the ecological principles, due to the developed urban area, 'green land' within a city started to diminish; and due to serious pollution, the environemental quality declined, and the living environment became sagged down even more seriously. it was analyzed to be a considerable point as a type of model for newly developing cities that are being undergone by the developmental and expansive plan by the City of Chun-chon.

The purpose of the study were to: (1) determine important home management concepts in the secondary home economics education curriculum,(2) identify the educational needs related to home management perceived by secondary school students, and the factors affecting it, (3) use the findings to make recommendations for developing home economics curriculum and teaching home economics in the secondary school. The questionnaires were distributed to the 1,029 secondary school students, lived in seoul, local cities, and rural area. The data were analyzed by using descriptive statistics, T-test one ay ANOVA with scheffe test, and multiple regression analysis. Forty home management concepts were selected based on the related literatures. Stress man-agement, leisure time activities, resource use, making money for adolescents, work simplication methods were the concepts which showed the highest level of educational needs perceived by the students. The educational needs were affected by sex, school level, residence area of the respondents, and other factors related to the perception about home economics such as preference, GPA, etc.

The purpose of this study was to identify (1) consumers' energy conservation attitude and behavior and (2) response to the energy conservation policies. For this purpose 1,200 male and female consumers who residents of 6 cities (Seoul, Pusan, Taegu, Kwangju. Taejoen, and Inchon) were surveyed through the standardized questionnares. The major findings were as follows; (1) The level of energy conservation attitude was relatively high and differed significantly according to sex, age, and education, (2) The level of energy conservation behavior was differed significantly according to sex, age, and education. (3) The energy conservation policies which provide consumers with energy saving information and education were more preferred. (4) There energy conservation attitude had the strongest effect on the energy conservation behavior.
