국가연구개발비의 규모가 점점 증가함에 따라 R&D 예산을 보다 효율적으로 관리하기 위한 논의의 중요성은 점점 부각되어져 왔으나, 정작 이에 대한 체계적인 연구는 부족한 편이다. 국가 연구개발 사업중 체계개발 국가사업은 일반적인 사업에 비해 구현 대상 시스템이 매우 복잡하고 많은 절차들로 이루어져 있어서 사업이 대규모이고 장기적인 편이다. 이러한 환경적 특성들을 고려하여 체계개발 국가 사업의 사전타당성 조사 분석시 체계개발 국가사업이 가지고 있는 높은 수준의 불확실성과 위험 요소들에 대한 철저한 분석을 바탕으로 적절한 평가방안의 도입을 통해 보다 효율적인 사전타당성 조사를 수행할 필요가 있다. 본 연구에서는 체계개발 사업의 기획안 분석에 사용되어질 수 있는 방법론들과 관련 연구들의 분석을 바탕으로 체계개발의 특성을 반영한 사전타당성 조사 방안의 개선 방향들을 시스템 엔지니어링, 비용/일정 관리, 성과 관리, 생애주기 고려, 위험관리, 요구사항관리, 그리고 프로세스 및 정책 관점에서 도출하였다.

The purpose of this research was to provide basic data to the welfare policy for the aged by studying the relation of health concern, health behavior, and subjective health condition between the aged and the preliminary aged group. Subjects were composed of a total of 259 (116 males, 143 females) living in seoul, aged 50-64(preliminary old people) and over 65(old people), and they were asked to answer the survey Questionnaires The data were analyzed by descriptive statistics, chi-square test, and spearman's correlation coefficient. As a result of the study, the preliminary aged group was significant than the aged group in all three variables. In the relation of health concern and health behavior, there was significance both for the preliminary aged(p〈0.01) and the aged group(p〈0.001). Also, there was significance in the relation of health behavior and subjective health condition of two groups(p〈0.001). However, in the relation of subjective health condition and health concern, there was significance only for the aged group(p〈0.001). For the correlation among three variables, there was significance in the relation between health concern and health behavior and between health behavior and subjective health condition of the preliminary aged group(p〈0.01), but there was significance in the relation between health concern and health behavior and between health behavior and subjective health condition of the aged group(p〈0.01).

In the standards, minimum reinforcement ratios are presented as the least reinforcement ratios that bearing elements should have in a way to include all systems and in general. However, naturally these general minimum ratios might be presented as being lower than the normally required reinforcement ratios by criteria such as system size, bearing system arrangement, section situation and distributions of the elements and earthquake effect. In this case, minimum reinforcement ratios may remain as meaningless restrictions. Then grouping the criterion that might affect reinforcement ratios according to certain parameters and creating minimum reinforcement ratios regarding preliminary design will provide ease and safety during the project designing. Moreover, it will enable fast and simple examinations in the beginning of project control and evaluation process. By means of the data which could be defined as "preliminary design & minimum reinforcement ratios", a more realistic and safe restriction compared to general minimum reinforcement ratios could be presented. As a result of numerous comprehensive studies, reinforcement ratios to include all certain systems might be obtained. Today, thanks to the development level of finite elements programs which can make reinforced concrete modelling, with the studies that are impossible to carry out beforehand, this deficiency in the minimum reinforcement ratios in the standarts may at least be partially made up with the advisory regulation of preliminary design & minimum reinforcement ratios. As the structure of the system to be examined and the diversity of the parameters range from the specific to the general, preliminary design & minimum reinforcement ratios will approximate to general minimum reinforcement ratios in real terms. By focusing on a more specific system structure and diversity of the parameters, preliminary design and even design reinforcement ratios will be approximated. In this preliminary study, a route between these two extremes was attempted to be followed. Today, it is possible to determine suggested practical ratios for project designs through carrying out numerous studies.

This study developed preliminary assessment methodology for priority listing of soil and groundwater contamination sources, considering source characteristics, local environments and risk receptors. Source characteristics were evaluated by scoring relative risk of contamination sources. Local environments were evaluated by scoring annual rainfall, hydraulic conductivity of aquifer, and annual groundwater use. Risk receptors were evaluated by scoring local population, direct distance to surface water, direct distance to drinking-water wells. Scores of each parameter were allocated by analysing distribution of parameter values obtained from government databases. Distributed scores of source characteristics local environments: risk receptors were 12 : 12 : 12. The preliminary assessment scored 0 to 36 for each soil and groundwater sources. Inventory of soil and groundwater sources consisted of 7 categories. This study applied the preliminary assessment methodology to Manan-Gu, Anyang City, Korea. The number of car repair and washing facility was the largest in the contamination source inventory. Petroleum storage facilities showed the highest assessment score. The preliminary assessment methodology also indicated that Anyang-Dong was the priority section among Anyang-Dong, Suksu-Dong, Bakdal-Dong. This study is the first trial for relative ranking soil and groundwater contamination sources by considering source and local characteristics. Therefore, further researches and revision of the preliminary assessment methodology need to be pursued for various applications.

The paper describes the preliminary ship design method using deterministic approach and probabilistic approach. In deterministic approach, there are computational aspects to applying not only the integration concurrently of principal dimension decisions and hull form variations but also hydrostatic coefficients that applied to optimization iterative process. Therefore, this paper developed that actual design concept at the preliminary ship design more than sequential design which separated in principal dimension decisions and hull form variations. Furthermore, a probabilistic approach at the preliminary ship design is applied to efficiently solve design information uncertainty that compared to deterministic approach.

The objective of this study is to present and to analyze preliminary orientation design factors in the design stage of sustainable architecture in the viewpoint of technocentrism. Typically people interpret solar energy system architecture as simply being part of a mechanical system. Yet, even before considering energy-consuming physical systems in buildings, it is very important to consider the outer parameters of sustainable design factors and the design process itself for the effective and suitable energy-saving design methodology. By analyzing the evolving phases and history of technocentrism and solar energy systems in sustainable architecture through examples and case studies, this paper focuses on and proposes preliminary orientation design factors that should be considered when starting the architectural design process in the viewpoint of technocentrism.
