To ensure that the production system of a factory is efficient, the factory layout design should consider the location and material flow plans of facilities, workshops, and storage areas. Highly productive factories need to have an optimized layout planning process, and a customized design methodology of the production system is a necessity for feasible layout planning. This paper presents a method for designing a layout module's size and shape and provides a heuristic location-allocation algorithm for the modules. The method is implemented and validated using a rich internet application-based platform. The layout design method is based on the leisure ship production process; this method can be used for designing the layout of a new factory or remodeling an existing factory and its production system. In contrast to existing layout methods, the inputs required for the proposed method, such as target products, production processes, and human-resource plans, are simple. This layout design method provides a useful solution for the initial stage of factory design.

The concept of universal design has become an essential requirement for environmental design, due to the growing population of the aged, and the increasing needs of people with disabilities. This study aims to propose a universal design guideline for apartment housing units that can be adapted to both a general household and a household with elderly or disabled individuals. This design process encompasses literary reviews, and includes the measurements of the dimensions and facilities of currently available apartment housing. The three domestic universal guidelines were reviewed, and a universal design checklist for apartment housing units was developed. Afterward, the individual elements and inclusive factors of universal design, for apartment housing units, were collected and examined according to the each functional space within the home. The results and conclusions are as follows: 1) The factors of universal design are diversified by the division of the functional spaces within the home, such as the private space, the work space and the entertaining space. 2) Due to the lack of space and storage, wheelchairs cannot be used in most currently available apartment types; this problem can be resolved by applying flexibility and optional adaptation. The solutions for the above are additional design factors that will enable more convenient usage and elaborate design.

This study examined the general housing awareness and awareness on house sharing of college students who are present residents as well as potential residents of shared houses. To achieve this purpose, structured questionnaires were used as a survey tool to understand students' awareness on housing and opinions on house sharing including a range of space sharing, preferences on house mates, and demands on services and facilities. The survey was conducted of college students in Busan, and the data were analyzed by the PASW Statistics 18.0 program. The findings of this study are as follows: 1) The housing awareness was categorized into seven factors by factor analysis. The subjects valued 'personality factor' in the housing awareness. 2) Regarding preference of house mate type, participants preferred a person who has similar lifestyle and in the same gender. 3) As for the space sharing, the subjects didn't want to share a bathroom and shower. Also, they preferred medium or large scale dormitory layout type to small sized apartment type. 4) The most positive aspect of house sharing was 'Reduction of rental and maintenance cost'. On the other hand, 'Difference of daily life pattern' was the most negative aspect of house sharing. 5) In case of services and community spaces, they preferred 'delivery storage service' and 'coin-operated laundry facility'.

Through a field study of the folk houses, 'Closed ㄱㄴ Type' in Goyang-si, Gyonggj-do, focused on the dweller's life by the method of ethnographic interview, observation, and physical survey. L and opposite L type of inner and outer buildings form a closed inner court, and innermost backyard for woman is enclosed by fence. Form and space of the house contains dweller's traditional life. Outer space of a front gate becomes semiprivate space, for thrashing and piling up harvest and raising vegetables and pigs. Confucius principle does not fully dominate dweller's life of ancestral rite at Daecheong floor, and separation of man's and woman's quarter. Superstitious worship activities took place for lord of site and house. In everyday life, Anbang, inner main room, is assigned for parent's quarter instead of woman's quarter, and Geornbang, next room, was for son's family. Anbang has symbolic meaning for a place of deathbed. House contains agricultural activities, crop harvesting, thrashing, putting into storage, hulling rice, and keeping grain near kitchen. At present, rooms are needed more; sheds are made into rooms, rooms are enlarged toward outside, half outside space like Daechong floor becomes interior space by sash screen. And modern facilities of kitchen and bathroom are equipped for convenience. At the end, meaning and generative principle of those forms are discovered.

In domestic island regions, the power supply generally depends on diesel generators due to difficulties of grid connection. To solve this issue, recently, the study on the stand-alone microgrid technology and its test are being actively conducted. In this paper, we propose the stand-alone microgrid integration monitoring system for energy independence island. First, we design the software architecture for monitoring of solar, wind, diesel power generation facilities, transmission and distribution of grid network, and energy storage system. Then, we implement the monitoring software that allows administrators to identify and run the monitoring software easily.

Excavation of underground openings changes stress distribution around the opening. The survey of this disturbed zone in excavation is very important to design and construct underground facilities, such as tunnel, gas and oil storage, power plant and disposal site of high- and low-level radioactive wastes. This paper presents a zoning of rock masses with tunnel excavation using PS logging. Compressional and shear wave velocities are measured in boreholes drilled in the tunnel wall, which was constructed with blasting and/or machine excavation. The disturbed zone in excavation can be estimated by comparing PS logging data with a tomographic image of compressional wave velocity and compressional and shear wave velocities of core samples. In the side wall of tunnel, the disturbed zone reaches 1.5 m and 1.0 m in thickness for blocks of blasting and machine excavations, respectively. In the roof of tunnel, however, the disturbed zone is 1.0 m and 0.75 m thick for the two blocks. These results show that the width of the disturbed zone is larger in the side wall of tunnel than in the roof, and 1.3 to 1.5 times larger for the blasting excavation than for the machine excavation.

The present problems concerning the control of generation, storage, collection, transfer and transport, processing and disposal of the municipal waste are serious. And the transportation of the municipal waste is recently a important part of solid waste treatment and disposal. The waste pneumatic transportation system is expected to be an effective method for use in solving that problems. In this study, pneumatic transportation system was applied to 2,000-5,000 households of public/group housing for economic and technical analysis on the basis of data for working and operation. The proper equipment must be selected through economic and technical analysis for generation and properties of waste because the equipment in facilities of system is various. And the efficient operation method should be studied on the basis of information on the record of oeration. As the wet food waste clogs the pipeline, it is necessary to examine under the actual condition. The maximum unit waste generation rate based on the assumption that each household is comprised of 3.20 people is determined $2,340g/household{\cdot}day$, and it is included the 50% increase of seasonal and daily change.

Burials for the rapid disposal of carcasses have diverse and profound effects on the rural living condition, natural environment, and local economy throughout construction, management and final destruction of burials. In this study, possible residue excavated from standard burials, storage using FRP (Fiberglass Reinforced Plastic) tanks, and microbial-treated burials are characterized as carcasses, contaminated soil by leachate, and wasted plastic film. Treatment technologies for volume reduction of the residue including composting, rendering, and thermal hydrolysis were investigated. If the solid and liquid residues generated during volume reduction treatment are directly transferred to the environmental facilities, it may cause disorder due to high concentrations of organics, antibiotics, and lipid. Benefits and drawbacks of composting as a volume reduction techniques are extensively investigated. We also discussed that proper treatment of excavated soils and the reusing the treated soil as agricultural purpose. For the protection of public health and worker's hygiene, treatment criteria including produced residue qualities, and quality standards for the treated soil as agricultural use are required. In addition, Scientific manual for the proper treatment of residues is required. It is necessary to consider the establishment of a pretreatment facility to the occurrence of large-scale residue treatment.

도시지역에 있어서 홍수피해의 직접적인 원인으로는 외수의 범람에 의한 침수와 내수 배제 불량에 의한 침수피해로 구분할 수 있는데 최근 도시지역에 발생하는 홍수피해의 대부분은 외수의 직접 범람에 의한 피해보다는 각종 수리구조물의 배제능력 부족이나 방류지점에서의 배수위의 영향으로 인한 내수의 배제 불량에 기인한 피해가 증가하는 추세이다. 또한 최근 도시지역에 홍수피해를 유발하고 있는 강우의 특징은 단시간에 많은 강우가 집중하여 발생하는 국지성 집중호우로 단시간 내에 수공구조물의 기능을 마비시킴으로써 침수피해를 가중시키는 경향이 있으므로 배수시설 설계 시 이러한 강우의 특성과 도시유출 특성에 대한 고려가 요구되며 중요 시설물에 대해서는 설계빈도의 상향조정이 필요하다. 본 연구에서는 기존 도시유역에 적용되고 있는 강우-유출모형의 기본이론의 장 단점을 검토하여 본 연구의 목적과 용도에 가장 적합하다고 판단되는 SWMM 모형을 선정하여 적용하였다. 대구 서구 비산 7동 배수구역의 유출모의를 실시한바, 향후 경제적 편익을 고려하고, 정확한 실측 유량자료 값을 산정, 관거 내 유속을 방해하는 토사 등 보다 정확한 관거자료, 모의에 사용하는 각종 매개 변수값의 정확도를 높인다면 인위적인 배수계통을 가지는 도시유역에서의 각종 풍수해에 피해를 최소화 할 수 있는 보다 합리적인 방재대책 수립에 큰 도움을 줄 것으로 판단된다.
