The goal of this study is to figure out the remodeling cycle at high-rise apartment housing and to analysis on quantity of $CO_2$ emission about remodeling cycle. The process of research is as follow; 1) Estimate the remodeling cycle through survey targeting residents at high-rise apartment building. 2) Simulate conditions on the high-rise apartment housing. 3) Calculate quantity of energy consumption and $CO_2$ emission 4) Derive elements that are on high level of environmental load evaluation. The main results of this study is as follow; 1) The cycle of finishing such as wallpaper is shorter than the cycle of building equipment such as elements in a toilet. 2) According to result of calculating $CO_2$ emission, fabric wallpaper and mortar are main factors that impact on the environment. The results is important to show reference points on quantitative measuring evaluation for the environmental-friendly extent.

The purpose of this study is to investigate the ramen selection attributes of consumers. This research assigned taste, price, quantity, design, and brand as selection attributes, all of which have already been verified by previous studies as selection attributes when purchasing processed foods. A total of 500 questionnaires were issued, and the survey results were analysed to ensure validity and reliability. A Structural Equation Model was used to test the hypotheses of the study. Based on the analysis, taste, price, quantity, design, and brand had a statistically significant effect on satisfaction. Furthermore, satisfaction had a statistically significant effect on repurchase intention. Among the selection attributes (taste, price, quantity, design, and brand), only price had a statistically significant effect on repurchase intention. However, the influence of the selection attributes on satisfaction varied depending on the consumer's consumption value. In order to analyse the moderating effect of consumption value, the respondent group was divided into a hedonism group and pragmatism group, and analysed. It empirically proved that the hedonistic value-oriented group valued taste, and the practical value-oriented group valued price the most. This study empirically verified the relationship between ramen selection attributes and consumption value, and provided corresponding theoretical and practical implications.

Issues and problems in formulating South Korea's water resources policy are discussed in terms of water quantity and quality. South Korean needs both water conservation and water supply capability for the growing population and economic activities. The government has attempted to build more large-scale dams to store and supply water for residential, farming and industrial uses, but the environmentalists who emphasize conservation and environmental protection oppose the government. The environmentalists are popular among the general public. Water quality has been deteriorating from point- ad non-point sources. urban and farm runoffs are serious pollutants. All want by preserve water quality. There is no dispute on this matter between the government and the environmentalists. Money is hard to come by to preserve water quality. Economic and financial crises and no self-sufficient local governments' revenue structure are pessimistic. Basic survey on water resources, hydrology and hydraulic is badly needed for the future water resources planning.

The purpose of this study is to investigate the current state of the contents of the mathematics education that are implemented for 3-10 grade students in Korea. To satisfy the purpose of the study, we conducted a nationwide questionnaire to get opinions from students on the relevance of the mathematics curriculum. 4,158 elementary school students, 4,571 middle school students, and 1,653 high school students participated in this survey. Many students feel that the quantity is relevant, so the requirement of reduction in quantity is a little. Also secondary students feel that mathematics is difficult and this condition becomes more serious in proportion as grade. Finally we noticed the difference between sexes, grades, and tracks of studying in every question.

This is an exploratory study to describe drinking patterns and problem drinking and alcohol-related problem in college students. The major purpose of this study is to describe the prevalence of drinking styles, the quantity of alcohol getting drunken and the describe the frequency of drunkenness in the previous 12months prior to the survey, and to examine the patterns of how various drinking behaviors are different by drinking style. We used the scale for measuring problem drinking NAST(1), AUDIT, indicated that males drank more and more and more frequently, and had episodes of drunkenness and more accepting of drinking than females, the amount of alcohol becoming intoxicated, the frequency and quantity of alcohol consumed in the month, and the frequency of intoxicated were significantly different by drinking styles in both sexes. A problem drinking rate, danger drinker 49.3% dependence drinker 3.5% in ADULT and alcohol dependency 9.7% in NAST(1) It will be necessary to discuss about adequate policy and eucation protrams to be able to curb collegiate's alcohol abuse.

Construction industries worldwide have moved to Building Information Modeling environment in conjunction with IT technology progress. Korean domestic construction market is in the midst of enthusiastically adopting BIM technique and the public sectors try to apply the method to their projects. Difficulties have been introduced, however, in doing so mainly due to the complexity in reflecting the distinctions of the public cost estimate requirements to BIM modeling. The main objective of this study is to propose four kinds of BIM property information modeling methodologies which would be used in the quantity surveys of the public construction projects. To evaluate the applicability of the suggested modeling methods, the research performed a case study.

This study was carried out to investigate the dose of prescription in Shanghanlun. To this end, literature research and a survey of several herbal medicines have been done. As a result, the weight of 1 liang (兩) is determined to be about 15g. Furthermore, we find that Jung-Kyung Jang, who compiled Shang-hanlun, used a great quantity of herbal medicines to treat critical conditions of iIInesses. Therefore application of Shang-hanIun s prescriptions according to the various conditions of patients must have changed the quantity of dosage.

Current and planned deep multicolor wide-area cosmological surveys will map in detail the spatial distribution of galaxies and quasars over unprecedented volumes, and provide a number of objects with photometric redshifts more than an order of magnitude bigger than that of spectroscopic redshifts. Photometric information is statistically more significant for studying cosmological evolution, dark energy, and the expansion history of the universe at a fraction of the cost of a full spectroscopic survey, but intrinsically carries a bias due to noise in the distance estimates. We provide convolution- and deconvolution-based algorithms capable of removing this bias -- thus able to exploit the full cosmological information -- in order to reconstruct intrinsic distributions and correlations between distance-dependent quantities. We then show some direct applications of our techniques to the VIMOS Public Extragalactic Redshift Survey (VIPERS) and the Sloan Digital Sky Survey (SDSS) datasets. Our methods impact a broader range of studies, when at least one distance-dependent quantity is involved; hence, they will be useful for upcoming large-volume surveys, some of which will only have photometric information.

센서스 조사가 개인의 권리를 침해한다는 이유로 헌법재판소의 소송이 제기되었던 독일의 경우와 같이 사회가 발달하고 민주화될수록 통계조사의 어려움이 가중되고 있다 . 또한 조사비용이 증대하여 예산의 압박을 받고 요구되는 정보의 양과 질도 다양해지는 등, 조사환경이 급속하게 변화하여 신속하고 정확하며 객관적이고 타당성 있는 통계의 생산에 많은 어려움이 생긴다. 이러한 환경의 변화에 적절히 대응하기 위해서 우리나라의 통계제도의 현황을 살펴보고 주요 국가들의 통계제도를 검토한 후, 우리나라에 적합한 통계제도의 개선을 위한 방향을 제시하였다.
