현행 부설주차장 설치기준은 평균적인 의미의 주차유발원단위로 위락시설, 문화 및 집회시설, 단독주택, 공장, 창고시설 등 9개 설치대상 시설물 그룹에 13개의 설치기준을 주차장법에 따라 적용하고 있다. 최근 건축물의 종류가 다양해지고 기능이 혼재되어 같은 시설물 그룹에 속하더라도 시설물의 용도 및 규모에 따라 설치기준을 세분화 할 필요가 있으나, 대부분 지자체의 경우 체계적이고 일관된 기준 없이 주차장법에서 제시된 시설분류기준에 강화된 획일적인 설치기준을 적용하고 있어 자원의 낭비를 초래하고 있다. 특히, 산업단지 내 위치한 대규모 첨단제조시설의 경우 공정이 자동화되어 건물규모대비 근무인력이 소수임에도 불구하고 이에 대한 별도의 세부적인 구분 없이 공장시설로 분류되어 일반 제조공장과 동일한 일괄적 기준을 적용하고 있다. 따라서 본 연구에서는 현장조사를 통해 산업단지 내 공장시설에 대한 기존 주차원단위 산정에 대한 문제점을 분석하고, 이를 해결하기 위한 방안으로 시설물의 용도 및 규모특성을 고려한 주차수요예측모형을 제시하였다.

현행 주차장법상의 부설주차장 설치기준은 위락시설, 문화 및 집회시설, 단독주택, 공장 등 설치 대상 시설물을 9개 그룹으로 분류하고, 그룹 내 시설물에 대해서는 동일한 설치기준이 제시되어 있다. 지자체는 필요에 따라서 지자체 조례로 시설물의 종류를 세분하거나 설치기준의 2분의 1의 범위(${\pm}$50%) 안에서 이를 강화 또는 완화할 수 있도록 되어 있다. 최근 건축물의 종류가 다양해지고 기능이 혼재되어 같은 그룹에 속하더라도 시설물에 따라 주차장설치기준을 세분화할 필요가 있으나, 대부분 지자체의 경우 체계적이고 일관된 기준 없이 주차장법에서 제시된 시설분류기준에 강화된 획일적인 설치기준을 조례에 적용하고 있다. 특히, 산업단지 내 위치한 대규모 첨단제조시설의 경우 공정이 자동화되어 건물규모대비 근무인력이 소수임에도 불구하고 이에 대한 별도의 세부적인 구분없이 기타시설 또는 공장시설로 분류되어 일반 제조공장과 동일한 일괄적 기준을 적용하고 있다. 따라서 본 연구에서는 현장조사를 통해 산업단지 내 공장시설에 대한 기존 주차원단위 산정에 대한 문제점을 분석하고, 이를 해결하기 위해 방안으로 용도 및 규모특성을 고려한 부설주차장 설치기준 개선방안을 제시하였다.

In order to study ecology of microorganisms during Takju brewing, microflora changes were examined fromm the start to the sixth day of Takju fermentation in 24 hours intervals. Takju made from rice, flour and dried sweet potato in a liter volume open container at the laboratory and a sanple of Takju brewing factory were studied for their microflora and their changes during fermentationl together with a sample of Kokja. Results obtained were as follows ; 1. The followings were the identified microorganisms in Kokja. The molds ; Absidia spinosa, Aspergillus parasiticus. The yeasts ; Candida melinii, Candida Solani, Hansenula anomala. The bacteria ; Luctobacillus casei, Leuconostoc mesenteroides, Bacillus subtilis, Bacillus pumilus. 2. Torulopsis inconspicua, Lactobacillus casei, Leuconotoc mesenteroides, Bacillus subtilis, Bacillus pumilus were isolated from main mash of laboratory-made Takju samples. The yeast, Torupsis inconspicua which was not present in Kokja and, probably of a contaminant yeast, dominated the yeast flora of Takju mash of rice, flour and sweet potato of labotatory brewing. The laboratory brewing lost also always showed large population of lactic acid bacteria flora. 3. None of the wild yeasts which were present in Kokja appeared in Takju mashes. The Kokja appears to be of no use as the yeast source for Takju fermentation. Also the Kokja appears to be of not so effective amylolytic and proteolytic enzyme sources considering the microflora characteristics. Probably the major role of Kokja in Takju fermentation may be to contribute in taste formation. 4. Inoculation of Sacharomyces cerevisiae into the mash to the level of $10^7$ ml at the start of fermentation greatly changed the ecological aspects eliminating conditions of rather slow rising of natural contaminant yeast populaiton and fermentation which might give rise to prosperity of lactic acid and Bacillus bacteria that would be avoidable. 5. Examination of microflora of the large factory scale Takju fermentation showed the quite similar pattern of microflora and their changes to that of the cultured yeast-inoculated laboratory batch Takju fermentation. The cultured yeast dominated as the only predominant microflora, and the lactic acid bacteria flora were completely suppressed and aerobic bacteria, greatly. Probably this may be the regular microflora pattern of normal Takju fermentation. The role of lactic acid bacteria and aerobic bacteria in Takju fermentation may not be clear yet from this experiment alone.

Utilizing of the geotextile container shows several advantages such as standardized construction, factory manufactured products, the control of quality, workability, and economical point of view. Recently this technique can be applied to rehabilitate the loss of rail roadbed due to the heavy rainfall. In this study, a large-scale laboratory test were conducted with simulation of static performance on the geotextile container reinforced rail roadbed. Based on the laboratory test results, the vertical pressure distribution with respect to the depth, and settlement of rail roadbed were measured and compared test results between geotextile container reinforced case and unreinforced case. Thus, the effectiveness of reinforcement was evaluated in terms of its performance and stability.

This paper focuses on development of a performance manager for IEEE 802.4 token bus networks to serve large-scale integrated systems. In order to construct the management algorithm, the principles of fuzzy logic, genetic algorithm, and neural network have been combined to represent human knowledge and to imitate of human inference mechanism. Through the simulation experiments, it is shown that the proposed performance manager is capable of improving the network performance without a priori knowledge.

This paper focues on development of a timer selection algorithm for IEEE802.4 token bus networks to serve large-scale integrated manufacturing systems. Such factory automation networks have to satisfy delay constraints imposed on time-critical messages while maintaining as much network capacity as possible for non-time-critical messages. Therefore, the object of this paper is to develop timer selection algorithm to minimize a certain penalty function. This paper presents an algorithm based on Genetic Algorithm. The efficacy of the algorithm has been demonstrated by a series of simulation experiments.

Conventional water treatment facilities like precipitation process need large-scale equipment and wide space to purify the wastewater of paper factory. In case of massive waste water, high gradient magnetic separation (HGMS) parts are more effective to purify it rapidly and to occupy relatively small space, since large voids at filter with HGMS are adopted. Cryo-cooled Nb-Ti superconducting magnet with room temperature bore in diameter of 100 mm and 600 mm in height was used for magnetic separator. Magnetic filters were designed by the analysis of magnetic field distribution at superconducting magnets.
