To improve concrete tensile strength and bending strength, New plan that have more economical and simple manufacture process is groped. By an alternative plan, chemical pre-stressed concrete is presented. In this study, we analyzed the rheological properties of cement paste with the kind and replacement ratio of k-type CSA type expansive additives that is used mainly in domestic. and we suggested that the algorithm of a mixing plan in the chemical pre-stressed concrete and from this, we presented the basic report for the right mixing plan. From the results, Flow increased more or less according to use of expansive additives. This phenomenon was observed by increasing paste amount that shows as substitution for expansive additives that specific gravity is smaller than that of cement. As linear regression a result supposing paste that mix expansive additives by Bingham plastic fluid. The shear rate and shear stress expressed high interrelationship. therefore, flow analysis of quantitative was available. The plastic viscosity following to replacement ratio of expansive additives is no change almost, the yield value is decreased in proportion to the added amount of expansive additives. Through this experiment, we could evaluate rheological properties of cement paste using the expansive additives. Hereafter by an additional experiment, we must confirm stability assessment of material separation by using the aggregate with the kind and replacement ratio of expansive additives.

Photo-lithography lies in the middle of the wafer fabrication process. It is often considered as the most critical step in the IC process. We use a mask in exposure steps of the photo-lithography. Typically, 20 to 25 different levels of masks are required to complete an IC device. That means, if a photo process can be developed with the use of only one photo mask, we can reduce more process cost. To satisfy this, we plan to develop an alternative photo mask. For this reason, we chose to use a LCD. We expect to develop a LCD panel that can be changed by electrical control. This is the main idea about the adjustive photo mask. The Photo mask made of LCD panel will replace the former one.

According to the need for objectivity and convenience the whole planning process is devided into a secries of 8 systematic stages. But it is an unending upward spiral of incremented efforts toward improvement. So many activities should be carried out concurrently, providing a mutual supportive flow back and forth between various stages of the process depending on local conditions and requirements. The eight stages are: (1) Planning the Planning and Developing Planning Competence (2) Statements of Policy and Broad Goals (3) Data Gathering (4) Priority Statement (5) Statement of Major Alternative Proposals (6) Development of Detailed Plan (7) Implementation as a Part of the Planning Process (8) Evaluation The frame and function of the planning machinery must be adjusted to local conditions, and also flexibility is desirable, especially at the start, when adaptations are more necessary and more frequent.

Users' demands on the space are changing in variety. These demands include reasonable space and form, harmonious composition with surroundings and esthetic satisfaction that could be brought by personal tastes and preferences. In addition, models that are introduced from designing process and from various forms tend to lack objective decision making standard. Accordingly it is difficult to find a clear alternative plan and process. In an effort to solve these problems, the objects of this study are; to propose an analysis model of image and space by using image process techniques that are on study in the field of artificial intelligence based on acquisition of digital image and to verify the application possibilities of such analysis model, 'Isovist' on quantitative analysis. The model can be applied with variable analysis model, as digital image process and other analysis model such as 'Isovist' It is possible that further study can complement problems from this study.

본 연구는 임상실습과 임상실습대체 교내실습 간의 간호대학생의 간호과정수행능력, 비판적사고성향, SBAR 기술지식의 차이를 비교하기 위해 시도되었다. 임상실습에 참여한 간호학과 3학년 학생 20명, 임상실습대체 교내실습에 참여한 학생 18명을 대상으로 자료를 수집하였다. 수집된 자료는 빈도와 백분율, 평균과 표준편차를 구하였고, t-test, ANOVA, 비모수 검정인 Mann-Whitney U-test, Kruskal Wallis test로 분석하였다. 연구결과 임상실습과 임상실습대체 교내실습 교육에 따른 간호대학생의 간호과정수행능력, 비판적사고성향, SBAR 기술지식 간에는 유의한 차이가 없었다. 임상실습에서 대학생활만족도가 높은 경우에 간호과정 수행능력과 SBAR 기술지식이 유의하게 높았고, 임상실습대체 교내실습에서는 간호학 만족도가 높은 경우에 비판적사고성향과 SBAR 기술지식이 높았고, 학점이 높을 때 비판적사고성향이 높았다. 향후 팬데믹 상황에 대비하여 간호과정 수행능력과 비판적사고성향 및 SBAR 기술지식 능력을 향상시킬 수 있는 체계화된 임상실습대체 실습교육 방안이 마련되어져야 할 것이다.

It is practically very important in multi-criteria long-tenn IRP process to develop the set of candidate resource plans that meet following two conditions. First, the number of resource plans should not be too large for computer job. Second, the unknown best plan should exist among the set of candidate plans. In this paper, several novel procedures are developed. The main idea of the procedures is the two-stage approach. The first stage is to find the set of feasible resource capacity mixes in given target year(s). And, the second stage is to find the set of alternative paths of resource options for each resource mix determined in the first stage.

Recently, the community developmental enthusiasm is activated and emerged with the varied developmental plans since the localization was implemented in Korea. But the anxious view of the environmental problems has been gradually heightened in the Environmentally Sound and Sustainable Developmental(ESSD). The local autonomy should listen to the public opinions because the people's anti-developmental movement could obstruct the development project in the community level. The Environment-friendly Rural Development Plan(EFRDP) pursues the development and the environmental preservation of the community at the same time. Therefore EFRDP reflects the local developmental intention and consideration of environmental preservation at the step of planning. Throughout the planning process the opinions of development and environmental preservation should be adjusted, the people's planning ability can be enhanced, and new creative alternative ideas will come out at times.

Off-Site Construction is being widely adopted as an alternative to solve endemic problems in construction industry such as low productivity and efficiency. However, it is strongly recommended to examine the transportation process to be optimized because it determines the size of a modular and influences the cost of the construction. Therefore, in this study simulation model for optimization of modular construction transportation plan was developed using AnyLogic. As a result of the study, the influence of trailer transport capacity and transport time increases as the number of modular which should be transported from factory to site increases.

본 논문은 영남지역의 발전과정과 주민들의 삶의 질을 고찰하고 앞으로 발전전망 및 그 과제들을 모색하기 위해 수행된 연구의 후편(後篇)이다. 최근 국가적 및 세계적 규모로 전개되고 있는 경제 정치적 전환에 따라, 영남지역을 포함하여 우리나라의 모든 도시 지역들은 발전을 위한 내 외적 여건들의 변화과정을 겪고 있다. 각 지역들은 이러한 여건변화를 면밀히 검토하여 지역발전을 위한 장기적 전망과 목표를 설정하고 이를 실현시키기 위한 계획과 개발전략들을 입안 시행할 것이 요구되고 있다. 이러한 점에서, 본 논문은 영남지역의 발전 여전을 재검토하고 대안적 개발계획을 제시하는데 목적이 있다. 이를 위해 본 논문은 우선 우선 영남지역의 발전을 규정하고 있는 여건들의 변화를 각 측면별로 살펴보고, 영남지역에서 현재 추진되고 있는 개발계획의 현황과 의의 및 문제점을 검토한 후, 영남지역 발전 방향에 지침이 될 수 있는 대안적 지역발전모형과 지역사회 각 분야별 발전과제를 논의하고, 끝으로 영남지역 발전을 위한 구체적 개발계획을 분야별 및 권역별로 제시하고자 했다. 본 연구의 결과로, 영남지역은 사회공간적으로 균형된 발전 즉 한편으로 지역간및 전체 사회와의 유기적 관계 속에서 지역의 경제적 자립성 강화와 다른 한편으로 지역내 주민들의 인간다운 삶을 위한 사회적 제도 개선을 동시에 추구하는 계획을 수립 시행해야 할 것이 주장된다.
