The purpose of this was to test the interactive effects of usage situation and personal characteristics on perceived risk, importance of store attributes and store-type choice. The data were collected via a questionnaire from 601 housewives of ages 20's∼ 50's living in Seoul, Korea, and analyzed by factor analysis and repeated measure two-way ANOVA. The results of this study were as follows: First, the interactive effect of age and situation on economic risk was significant. Second, the significant infraction of age and situation on importance of product price/variety was found, and there were significant intractions of education and situation on importance of service/convenience, discount policy and product information sources/promotion. Third, the interactive effects of situation and personal characteristics (age, income, education or job) on store-type choice (brand chain store, discount store, department store, designer boutique, local store or a wholesale market) were significant.

Environmental issues are currently in the forefront of the political and economic area both globaly and nationally. In the all spheres of socio-economic development and policy, it is suggested that there are need, to measure environmental impacts and to produce and disseminate environmental statistics systematically for environmentally sound and sustainable development. Specially, because environmental statistics encompass a wide spectrum of sectors from the natural to the social sciences and are dispersed among various agencies, an organized approach and compilation methods in complicated fields such as environment are required. This article includes the methodology on the framework for development of environmental statistics to advance korean environmental statistics.

본 논문은 국내 사이버가정학습에서의 학습자 몰입을 형성하는 조건과 몰입, 그리고 학습 성과에 대한 영향간의 관계에 대하여 연구하였다. 이러한 탐구를 위해 Csikszentmihalyi(1990)의 몰입이론(flow theory)을 이론적 기반으로 삼았으며, 컴퓨터 매개 환경(Computer-Mediated Environment)에서의 학습활동에 참여하고 있는 사이버가정학습 수강자 310명으로부터 자료를 얻어 실증적 연구를 수행하였다. 사이버가정학습 학습자의 몰입은 '즐거움', '원격현존감', '주의집중', '관여', '시간왜곡'의 5가지 하위구인으로 정의하였고, 몰입 선행 조건은 학습에 필요한 '기술'과 과제수행의 '도전' 정도에 대한 개인의 인지도의 차이로 정의되었다. 실증적 연구를 위해 사이버가정학습 몰입측정 도구(Cyber-class Flow Measure)를 활용하였으며, 실제 몰입도 측정 후 몰입도가 높은 학습자 집단과 낮은 학습자 집단의 특성을 비교 분석하였다. 자료 분석결과 사이버가정학습 몰입도는 학습만족도 평가에 유의미한 영향을 미침을 보여주었다.

This paper analyzes how levels of logistics standardization are related to logistics costs. The study surveyed ratios of standard pallet use in order to measure levels of firms' standardization in logistics management. Research focused on how firms' logistics costs were related to their levels of logistics standardization and ratios of standard pallet use. After measuring use of standard pallets and logistics costs, optimal levels of logistics standardization were estimated based on survey data. Logistics costs and standardization were more related to labor than to freight volume or export. Results indicated that firms could reduce logistics costs by raising levels of logistics standardization; optimal levels of standard pallet use out of Korean firms' total manufacturing cargo volume were estimated at 44.26% for multi-standard pallets and 57.99% for a single standard pallet (a unit load system). The study demonstrated that adopting a single standard pallet results in better cost saving logistics systems than use of multi-standard pallet types. These results may explain why firms pursue standardization in logistics systems.

In order to establish railway long-tenn safety policy, various railway safety indexes are required. But these indexes are not use efficiently due to the limitation of safety information. Recently m any safety related information have been obtained based on Railway Safety Act 2004. In this study, various safety index, which can be applied both preventive safety activities and safety measure development, are proposed. These safety indexes are based on common safety index in European Railway Agency, but also include special index in Korea. Proposed safety index include accident results, precursors to accident, infrastructure, accident cost and safety management system. These indexes will be applied in railway industry from 2009.

To improve educational excellence and quality, academies carry forward integrative security model related to academic affairs including personal information. This paper proposes an integrative security model for academic affairs database, which guarantees DBMS access control, confidentiality, integrity, and security inspection. This proposed model considered that most academies can't make good use of data security product and suggests a detailed measure to realize the confidentiality based on the function of DBMS.

Communications is becoming a vital sector to lead Information Society in the nearfuture. In that sense the price system of its services is now being discussed seriously among the people who are directly and indirectly related to communications development. Input-Output analysis model developed by W. Leontief in early 1930's is a very useful tool to measure the price linkage effects in the national economy, which would be induced from the shift of a certain sector's price. 1980's I-0 table with 19 sectors is rear-ranged and applied to price analysis model, in which communications is treated as a exogenous sector, to see the price impacts generated from a change of telephone rate. With the results of this study, the authorities concerned with price policy can make their decisions more reasonable.

Does financial development contribute to economic growth? The literature finds that an expansion in financial resources is useful for economic growth if the degree of financial development is under a certain threshold; otherwise, the expansion is detrimental to growth. Almost every published study, however, considers country-panel data. Accordingly, the results are not directly applicable to the Korean economy. By examining Korean time-series data, this paper finds that there is an inverse U-shaped relationship between the per capita real GDP growth rate and private credit (as a percentage of nominal GDP)-a well-known measure of quantitative financial development, where the threshold is 171.5%. This paper also finds that private credit is positively associated with economic growth if the share of household credit out of private credit is less than 46.9%; otherwise, private credit is negatively associated with economic growth. As of 2016, the ratio of private credit to GDP and the ratio of household credit to private credit are both higher than the corresponding thresholds, which implies that policymakers should place more emphasis on qualitative financial development than on a quantitative expansion of financial resources.

We investigate the effect of introduction of the bancassurance system on cost efficiency in the Korean insurance industry between 1997 and 2012. Our estimation results indicate that introduction of this system contributed positively to efficiency of life insurance companies in Korea. Increase in a one standard deviation of bancassurance increases cost efficiency by 0.08 which is equivalent to 12 percent of mean cost efficiency. Recognising that the bancassurance system is a relatively new concept, our results indicate that the bancassurance system can be a policy measure to improve productivity in an emerging insurance market. The results illustrate that positive effects have accrued particularly to medium-sized companies and domestic companies, contrary to the prevailing perception that increased competition through bancassurance is more beneficial to large companies and foreign companies.

A few years ago, the rapid degradation of domestic air quality has led to the efforts of exhaust gas policy and fine dust mask, but it is not a fundamental measure. In Korea, photocatalyst will be applied to residential and multi-use facilites to purify indoor and outdoor air. Also, in this study, it is tried to produce exposed concrete that is aesthetically pleasing as well as air purification of indoor by combining with light transparent concrete according to the increasing interest in human indoor living environment. For this purpose, we have developed a block formwork for photocatalysis light transparent concrete and established a suitable manufacturing method for on-site construction.
