수치지도에 존재하는 등고선의 절점(Vertex)과 표고점을 이용해서 수치표고모형을 생성하기 위하여 일반적으로 TIN을 이용한 방법이 사용된다. 불규칙적으로 분포되어져 있는 데이터를 이용해서 TIN을 구성하는 알고리즘은 여러가지가 존재하는데 본 연구에서는 Incremental Insertion Method(IIM)를 이용하였다. 하천이나 인위적인 작업으로 지형이 급격하게 변화되는 지형을 TIN 에 표현하기 위해서 사용되는 Break Line 이 본 연구에 적용되었으며, 절점(Vertex)이나 표고점이 잘못된 높이 값을 가짐으로써 수치표고모형에 발생하는 왜곡을 보정하기 위해서 이들 데이터를 TIN에서 제거하는 방법에 대한 연구가 수행되어졌다.

NOW(Network of Workstations) is considered as a platform for running parallel programs by many people. One of the fundamental problems that must be addressed to achieve good performance for parallel programs on NOW is the determination of efficient job scheduling policies. Currently most research on NOW assumes that all the workstations in the NOW have the same processing power. In this paper we consider a NOW in which workstations may have different computing power. We introduce 10 classes of space sharing-based scheduling policies that can be applied to the NOW with heterogeneous computing power. We compare the performance of these scheduling policies by using the simulator which accepts synthetically generated sequential and parallel workloads and generates the response time and waiting time of parallel jobs as performance indices of various scheduling strategies. Through the experiments the case when a parallel program is partitioned heterogeneously in proportion to the computing power of workstations is shown to have better performance than when a parallel program is partitioned into parallel processes of the same size. When the owner returns to the workstation which is executing a parallel process, the policy which just lowers the priority of the parallel process shows better performance than the one which migrates the parallel process to a new idle workstation. Among the policies which use heterogeneous partitioning and process priority lowering, the adaptive policy performed best across the wide range of inter-arrival time of parallel programs but when the load imbalance among parallel processes becomes very high, the modified adaptive policy performed better.

This research was carried out to provide a good quality forest healing program as a basic source of development by researching the general characteristics of users of Geiji Mountain in North Jeolla Province, the recognition of forest healing and regional preference programs. As a result of the survey, Geigisan Mountain is used as a natural place for recreation and leisure of residents of Jeonju. The most important factors in the selection of forest healing programs for visitors were the activities, organization and chronology of the program, and the main purpose was to improve health. Week-by-week programs utilizing weekends were preferred for management of forest healing programs. It was revealed that sports programs prefer to enjoy natural scenery, forest experience programs, healing programs, forest therapy programs, meditation programs, and listening to forest music. The outcome of this study is expected to be used as a basic source for developing and researching a program for forest healing in the area of Mt. Meanwhile, the limit on the composition of suitable forest healing programs according to preference is required for continuous and continuous integrated study of the forest healing program for the future of the forest healing program.

The purpose of this study is to investigate the conditions for improving space use and satisfaction by examing the behavior, focusing on the senior center, one of the leisure welfare facilities for the older adults. An online survey was conducted on 300 older adults aged 65 years old (104 males, 196 females) who had experience using senior centers. The results are as follows. First, the frequency of use per older adults was 1-3 times a month the most, and the preferred frequency of use was 1-3 times a week. The results showed that they wanted to use the Senior center frequently, but they could not use it often. Considering the high preference for health promotion activity programs in senior centers, it is understood that the use of space programs for health promotion can be increased if provided. Second, as the usage time per route ranges from a minimum of 1 hour to a maximum of 5 hours, it is considered that satisfaction and usability can be improved if a space to support various personal activities is provided. Third, it is considered to be helpful to improve the program or space composition that can strengthen friendship or improve accessibility by appearing as difficulties in friendship and accessibility for the reasons not used per senior citizen.

The planning process of complex projects in tall building is characterized by the cooperation of many involved specialists and by a high degree of information exchange. In order to improve the quality of the structural design of tall buildings, information of different involved partners in the planning process has to be integrated. This paper aims to introduce a concept of the integrated structural design for the tall building using STEP(Standard for the Exchange of Product Model Data). In this study, the entities of mass, column shortening, and serviceability evaluation for structural design in tall buildings are proposed.

Genetic algorithm is one of the best ways to solve a discrete variable optimization problem. This method is an unconstrained optimization technique, so the constraints are handled in an implicit manner. The most popular way of handling constraints is to transform the original constrained problem into an unconstrained problem, using the concept of penalty function. I present the 3 fitness functions which represent the reject strategy, the penalty strategy, and the combined strategy. I make the design program using the 3 fitness Auctions and it is applied to the design problem of a gable frame and a 2 story 3 span frame.

내장형 시스템에 보다 강력한 성능이 요구됨에 따라 내장형 마이크로 프로세서는 보다 깊은 파이프라인을 채택하고 있다. 따라서, 내장형 마이크로 프로세서는 보다 정확한 분기 예측기를 필요로 하고 있다. 이러한 상황에서 분기 예특기의 구조, 성능 및 전력 소모와 전체 시스템의 전력 소모 사이의 trade-off를 분석하는 것은 매우 중요하다. 내장형 환경에서 시스템의 전력 소모는 설계 시 매우 중요하게 고려되어야 한다. 특히 내장형 시스템의 요구사항은 동작할 응용 프로그램에 의하여 규정되고, 전력 소모도 응용프로그램의 구조와 강하게 연관되어 있다. 본 논문의 목표는 내장형 환경에서 성능-전력 공간에서 분기 예측기를 분석하는 기법을 제시하는 것에 있다. 이를 통하여, 분기 예측기 테이블의 성능-전력을 고려한 최적화된 크기를 찾을 수 있다. 이러한 목표는 수학적 모델링을 통한 정량적 예측의 수행 및 시뮬레이션 결과와의 비교를 통한 수학적 모델링의 검증의 과정을 통하여 이루어진다. 결과는 우리의 수학적 모델이 성능-전력 공간에서 분기 예측기 테이블의 최적화된 크기 결정의 해법을 제공하고 있음을 보여주고 있다.

In this study, we attempted to propose operational directions for each space in order to transform the newly built library in Yangpyeong-gun into a space for cultural enjoyment and creativity development for local residents. To this end, the purpose is to understand the space composition status of Yangpyeong-gun public libraries and establish an operation plan (draft) for the space to be constructed. To this end, we analyzed the names, operation status, and cases of similar spaces in other libraries, and analyzed the spatial characteristics of library cases to establish a space operation plan for the Yangpyeong-gun public library. As a result of the study, it is important to utilize spaces such as children's resource rooms to improve early reading habits for infants and children, contribute to development, and develop various senses, and small theaters should be planned with a focus on large-scale performances. Furniture and space for reading and relaxation should be provided next to Byeokmyeonga & Bookstair, and it should be operated as a communication space where small talk is possible within a certain limit. It is necessary to operate the multipurpose room by activating experiential creative activities and creative performances. It is necessary for the club room to establish an operation plan through regular communication and opinion sharing. The maker space space is a space that supports various creative activities, and the general data room is a place that provides materials on all topics and must be operated by regularly communicating with users and reflecting their opinions. Lastly, I would like to suggest that the family room should be used like a book cafe where children and parents can freely drink tea together in the same space.
