In order to maximize an availability of machine and utilization of space, the parallel machines scheduling problem with space limit is frequently discussed in the industrial field. In this paper, we consider a scheduling problem for assembly machine in ship engine assembly shop. This paper considers the parallel machine scheduling problem in which n jobs having different release times, due dates and space limits are to be scheduled on m parallel machines. The objective function is to minimize the sum of earliness and tardiness. To solve this problem, a heuristic is developed. The proposed heuristic is divided into three modules hierarchically: job selection, machine selection and job sequencing, solution improvement. To illustrate its effectiveness, a proposed heuristic is evaluated with a large number of randomly generated test problems based on the field situation. Through the computational experiment, we determine the job selection rule that is suitable to the problem situation considered in this paper and show the effectiveness of our heuristic.

Interactions with the environment do to firm, deny, or challenge the existing knowledge. People who suffer from the loss of the sight have difficulty conceiving the space and the direction as well as walking. In the study, it wanted to reveal that the border that Is provided as a transfer clue has psychological and functional meaning to the sight-disabled people under given circumstances. It suggests that there is another space among the physical borders and analyzes the utilization clue in the entry space, which is the first starting point that can transfer, and obstacle factors which may happen at that point. And, it also wanted to present the surrounding environmental improvement ways for walking which is smooth and confident based on them.

The International Space Station (ISS) offers research opportunities to researchers through crew's space mission in the field of remote sensing. ISS provides the facilities to place and operate experiment equipments in a variety of fields, especially, microgravity experiments and Earth observations. This paper is intended to give readers a brief introduction to the ISS utilization and the capabilities for remote sensing researches. We investigate what kind of crew missions and payloads should be developed for remote sensing researches on the ISS.

Commercial remote-sensing is one of the applied fields of space activities which, like telecommunications but to a lesser extent, is in the process of recording a reapid rate of development. Fields of utilization for spatial imagery are numerous: ocean monitoring, crops monitoring, glaciology, meteorlogy, forestry, environmental watch, geology, etc. All those fields of interest could be gathered under the generic name of "earth-watching activities" which is somewhat larger than "remote-sensing." This article aims at presenting to Korean readers the main lines of development of five major players in the field, namely : the USA, France, Japan, Europe and Canada. This is not to exclude the role played by other active players such as the former USSR and other smaller though industrious space powers.

In this paper, we propose the methodology and system to show weather information to spatial system. When using the spatial information system, it is easy and convenient to show information such as target location, mission contents, enemy threats and so on. However, drawing 1-dimensional weather information on 3-dimensional space in spatial information system is hard task. To fuse data, we need to add a spatial layer including weather information to spatial layers and perform space modeling for showing weather information as spatial data in a virtual space. The virtual space is shown by receiving meteorological data and then changing in real time through weather database linkage.

LFS(Log-structured File System)는 쓰기 요청을 세그먼트 버퍼에 모으고, 세그먼트 단위로 순차 기록함으로써 무작위 쓰기에서도 최적의 성능을 보여준다. 그러나 디스크의 공간이 유한하여, LFS는 여유 세그먼트를 생성하는 클리닝을 수행해야 한다. 파일 시스템의 사용률이 증가함에 따라 세그먼트 클리닝 비용이 급격히 증가하는 단점이 있다. 본 논문에서는 LPS의 쓰기 성능 최적화를 위한 세그먼트 공간 재활용 기법을 설명한다. 이 기법은 유효 세그먼트를 재활용하여 여유 공간을 생성하는 방법으로 빈 세그먼트가 없이 쓰기요청을 처리 할 수 있다. 따라서 높은 비용의 클리닝 동작 없이, 데이터를 세그먼트 내 여유공간에 동적 재배치하여 쓰기요청을 처리한다. 또한 효율적인 세그먼트 공간 재활용을 위해 데이터 및 세그먼트의 지역성을 고려하는 분류기법을 설명한다. 실험 결과에서 이 기법은 파일 시스템의 사용률이 90%인 경우에도 기존 WOLF 기법을 사용한 LFS 보다 HDD에서 1.9배, SSD에서 1.6배의 성능향상을 보여준다.

It has been almost 20 years since Korea has started the research of school facilities, but there has not been any form of organized information or studies done about such a trend of the research. In this respect, this research places its focus on categorizing 44 policy studies initiated and proceeded by different organizations for last twenty years(1983-2004) and 186 volumes of the research about education facility plans and projects released by journal of Architectural Institute of Korea and journal of Korean Institute of Educational Facilities in 17 subjects of this study. It also concentrates on organizing data based on different levels of schools and periods of time as well as understanding the trend. The result of this research is followings. Considering every volume of the paper and the subjects that have previously been treated in those papers, the trend of this study is divided into the first stage of research period(1983-1993), the second stage of research period(1994-2001), and the third stage of research period(2002-present). Of all the papers, there has been the most number of papers objecting elementary schools(110 volumes, 56.1%), and most of them focused on space formation, size, and the present situation of utilization of each classroom in elementary schools. In the meantime, the studies about educational information, application of the media, space formation and size under teachers'consent, two-dimension types, a design of outdoor space(including gardens), the present situation of utilization, remodeling of school facilities, an evaluation of space and recognition-awareness analysis have been mainly done since 1995. Such a result mentioned above provides a sense of understanding about a level of studies about education facilities in our country, and as a basic source for future guidelines of studies and contents, in my personal opinion, it contains a high level of application.

It is a trend to pursue the reinforcement of child-centered, play-oriented ecological education programs that support children's development. Most of these nature friendly and eco education is done in the outdoor space. So outdoor activities in child care facilities are essential. The purpose of this study was to analyze the actual condition of the outdoor space for ecological child education in the child care center. Therefore, in order to provide the basic data for the direction of the improvement and to grasp the current situation and problems, the survey and analysis of the external space composition and utilization status in the child care facilities for nature-friendly ecological child care education has been done. As a result, the half of the cases did not reserve even the minimum size of outdoor space and fall short of the standards of outdoor space quality as accessibility, complexity, articulation and nature friendliness for ecological education. Therefore, in order to establish an ecological education environment, it is necessary to build facilities in natural green or suburban areas. In addition, they need to use the natural environment such as parks, open spaces, and forests.
