Ubiquitous computing is a vogue word, and its service is very popular in Korea. However, present ubiquitous service(u-Service) is thought to be more oriented to the provider's point of view, not the consumer's. To complement this problem, an online survey was performed for internet users, which consists of 24 single choice questions on six fields such as transportation, healthcare, environment/city-management, culture/education, administration, and industry. 2463 people joined the survey, who were grouped according to their age, resident region, level of education, and sex. Each group's demand for specific field of u-Service was examined. General level of demand was higher in case of the elderly and male than the younger and female for overall u-Service.

The objective of this paper is to construct pseudo-panel data set and estimate price and income elasticities of car travel demand, using 1995-2007 household income and expenditure survey data, in order to provide quantitative information for analyzing related policy effects in the transport sector. We categorized household survey data into 14 cohorts based on the birth year of the household head. As the result, a total of 133 pseudo-panel data sets was created for estimating price and income elasticities of car travel demand. Especially, price and income elasticities of car travel demand were separately estimated both short-term and long-term. We analyzed the panel model considering fixed effect within cohorts, using explanatory variables such as previous year's fuel consumption, real household income after tax, education level of the household head, the number of children under five, and the share of household type averaged by cohorts. As results, the short-term and long-term price elasticities of car travel demand were calculated as 0.2974-0.4280 and 0.4087-0.6275, respectively. Similarly, the short-term and long-term income elasticities were calculated as 0.3364-0.6281 and 0.7098, respectively.

This is a pilot study to survey the general demand of senior-assistive necessities before a standardization system for senior-assistive necessities is developed as well as to describe health professionals' opinions about the demand and quality of Oriental medical aids and necessities for daily living for the elderly. This is a descriptive survey in which 29 health professionals are questioned, using structured questionnaires based on ISO 9999. The questionnaires were developed by 7 expert conduction standardization system of senior-assistive products in Korea. The data is analyzed by descriptive statistics. The result is as follows : First, with regard to the demand for all of the items in Oriental medical aids for the elderly, the demand of cupping glasses is the highest, followed by instrument used to apply heat treatment, massage equipment, thermo-therapeutic mattress, and heat or ice packs. With regard to the demand for all of the items for the necessities for daily living for the elderly, chairs are the highest, followed by rolling chairs, beds for health, and heigh adjustable beds. Second, with regard to quality of Oriental medical aids, ${\ulcorner}$aids for hair care${\lrcorner}$ are the best, whereas ${\ulcorner}$aids for boiling Oriental medicine${\lrcorner}$ are the worst. In quality of the necessities for daily living, ${\ulcorner}$chairs${\lrcorner}$ are the best, whereas ${\ulcorner}$beds${\lrcorner}$ are the worst. Above all, this result shows that with ${\ulcorner}$aids for heat or cold treatment${\lrcorner}$, there is relatively high demand and low quaily of Oriental medical aids, and with ${\ulcorner}$Beds${\lrcorner}$, there is relatively high demand and low quality. Therefore, aids for heat or cold treatment and beds in th necessities for daily living are required to be developed for standardization of senior-assistive necessities.

The main purposes of this article are to introduce the theoretical backgrounds and empirical application methods of two different Models for the function of expenditure, and to compare the goodness-o(-fit of the two models: a single-equation model and a complete-system-of-demand-equation model. For the empirical analysis of the single-equation model, a linear formula and a double-leg formula were employed. In order to test the complete-system-of-demand-equation model empirically, the \"Linear Approximation/Almost Ideal Demand System (LA/AIDS)" was used. The independent variables were the total living expense and expenditure categories Price index. The data used in this study were obtained from the quarterly statistics of "The Annual Report on the Urban Family Income and Expenditure Survey (Dosigagyeyonbo)" and "The Annual Report on the Consumer Price Index (Sobijamulgajaryo)," for the years 1994 to 1997. The goodness-of-fit (R-square) was higher with the complete-system-of-demand-equation model than with the single-equation model for the budget share on food (excluding eating-out expenses) and for the share on cultural and recreational activities. However, there was no difference between the two models in terms of the proportion of the expenditure on automobile fuel.fuel.

This study aims to build a model dealing with the location decision of new manufacturing firms and their land demand. The model is composed with 1) the binary logit model structure identifying a future probability of manufacturing firms to locate in a city and their land demand; and 2) the land use suitability of the land demand. The model was empirically tested in the case of Anseong City. We used establishment-level data for the manufacturing industry from the Report on Mining and Manufacturing Survey. 48 industry groups were scrutinized to find the location probability in the city and their land demand via logit model with the dependent variables: number of employment, land capital, building capital, total products, and value-added for a new industry since 2001. It is forecasted that the future land areas (to 2025) for the manufacturing industries in the city are $5.94km^2$ and additional land demand for clustering the existing industries scattered over the city is $2.lkm^2$. Five industrial complex locations were identified through the land use suitability analysis.

Korea will soon experience a high demand for medical rehabilitation specialists, if it tries to deliver advanced health welfare service. In order to medical rehabilitation manpower policies, this study attempts to analyse, estimate and plan a long-term supply for physiatrists, physical therapists, and occupational therapists. The study analysed both national and foreign statistical data of manpower supply for medical rehabilitation specialists. A structured category of questionnaire was developed to survey the opinions of regarding the supply for rehabilitation specialists in Korea. Based on the above data, the demand of and supply for each specialists were estimated for long term up to the year 2030. Based on the comparative analysis results of the future demand and supply, the author intended to develop a new supply plan for the three specialist categories. The major findings of the supply plan are as follows : First, the replied proper mean ratios of rehabilitation professionals(physiatrists : physical therapists occupational therapists) appeared 1 : 5.93 : 3.59, and there is no significant difference between interprofessionals (p>0.05). Secons, the estimated demand for rehabilitation services by interprofessionals appeared significant difference among the interprofessionals (p<0.05).

This paper surveys the existing literatures on labor demand of Korea. It has been found that labor and capital are substitutes in Korea and the result holds even if labor is decomposed into white collar and blue collar workers. The elasticity of substitution lies between 0 and 1. It is yet unclear if employment and work hours are substitutes. The reduction of legal work week did not increase employment although decreased work hours. The labor demand elasticity is below 0.5 in the short run. Since mid 1990s, the technological change has shown skill bias and therefore increased demand for skilled labor.
