The markets are the basic urban facilities for maintaining daily life. Although the urban structure changed rapidly and the population quickly concentrated in the city, the markets remained traditional and backward. To solve various problems in the small excess markets, the Seoul Metropolitan Government had pushed ahead with the market modernization plan since 1967. The purpose of this study is to analyze the process of establishing the market modernization plan and the progress of this project, and to identify the historical meaning of this plan. The results of this study as follows; The market modernization plan aimed to modernize market operation system as well as buildings, and the Government was able to achieve its first goal by enforcing the construction of high-rise buildings, as the markets were newly built with the relatively large scaled fireproof structures. Despite its various limitations, these markets were also regarded as the model of the modern market.

Use of disposer at the kitchens of Korean apartments is inevitable in treating their foodwaste having a water content of more than 80%. Also we have to ensure that this extra disposer-foodwaste BOD loadings be treated properly by installing/operating a pre-treatment system before this wastewater enters public sewer system. However, the degree of BOD removal should not be excessive since a BOD/N ratio higher than 5 is required for removing N/P at a municipal wastewater treatment plant. The removal of BOD/N in the pretreatment system rather than BOD alone can be an alternative solution in solving this problem. The particles separated by sedimentation, screen or packed-bed can be anaerobically digested at apartment sites to generate biogas that can be used for simple digester heating and to generate volatile fatty acids (VFAs) for nitrogen removal. We suggest that Korean government grants a temporary license (say for 5 years) to foodwaste treatment companies in collaboration with apartment construction companies which may do business and develop various kinds of disposer-foodwaste treatment systems in diverse wastewater discharge systems of Korean apartments.

Evacuation facilities are installed so that people can evacuate high-rise apartment houses when it is impossible to escape fire through the front door. The households of apartment houses may escape the building in two ways, which will reduce loss of lives. This study examined the characteristics of two-way evacuation facilities, including a light-weight partition wall, shelter space at the balcony and horizontally-installed indoor emergency exit. Then, it proposed a horizontally-installed outdoor emergency exit that improved the problems of the examined facility types, and analyzed its economic-feasibility. When a horizontally-installed emergency exit instead of a traditional type to escape from fire is used, people may be more autonomous in deciding whether active evacuation is possible or not. Thus, the time required to evacuate the building with 4 different evacuation methods using the stairs and horizontally-installed emergency exit was simulated in consideration of the impact of evacuation methods that people choose on the time required for evacuation using pathfinder. Then, the simulation results were compared and analyzed. Any appropriate evacuation method to reduce the time required for evacuation was predicted, analyzed and decided. As a result of this study, it was analyzed that the high - rise apartment top - down type evacuation zone can shorten the total evacuation time compared to the staircase type.

한국 식품화의 위상은 구이류 및 전골류 조리시 발생하는 냄새, 연기, 기름 튐 등의 문제로 인해 낮게 평가 되고 있는 실정이다. 현재 사용하고 있는 불판 및 가열원료가 다양하여 맛의 균일화가 어렵고 사용 후 세척처리가 번거로운데다 환경오염까지 발생시킨다. 구이 및 전골에 소비되는 에너지가 잔량을 모두 섭취할 동안 연속적으로 공급하므로 에너지 소비 및 내부 공기조건이 열악한데 반해 연기 및 냄새와 관련된 제품의 개발과 생산에 참여하는 업체는 증가하고 있다. 하지만 기술력 및 자본력이 미미한 수준에 있어 많은 기술적 측면의 보완이 요구된다. 또 소스, 양념, 부재료 등의 가공처리를 외국인의 식문화에 적합하도록 맛, 향, 관능의 관점에서 규격화 및 현지화도 요구되며, 공급되는 원재료의 고기종류, 규격, 등급 등의 조건들이 국내 관능뿐만 아니라 외국인의 관능적인 관점에서 표준화가 시급하다. 주한 외국인을 대상으로 한 설문에서 59%가 한국음식의 세계화가 가능하고 89.9%가 한식메뉴를 소개할 의사가 있는 것으로 조사되었다. 이는 외국인 소비자의 인지도에서 불고기와 갈비 등의 구이류가 다른 한식보다 선호도가 증가하는 것이기 때문인 것으로 분석된다. 2009년 농림수산식품부가 '한식 세계화 프로젝트'를 선포하여 1만여 곳의 해외식당을 2017년까지 4만 곳으로 증가할 예정이다. 따라서 한식문화의 표준화를 위한 용어 재료 기구 단위 등의 표준화 기반개발을 바탕으로 조리 및 식문화의 표준화가 요구되고 있다. 우리나라는 구이전문점들이 일반주거 및 아파트 단지에 위치하고 있어 연기와 냄새에 대한 민원 및 분쟁이 발생되고 있다. 이에 집진, 제연 설비의 설치비용이 많이 소요되고 있으며 대부분의 구이설비가 수입제품으로 규모가 매우 크다. 일본의 경우 2002년도부터 음식점에서 발생하는 연기에 관한 규제를 법제화하였다. 위의 기술적, 경제 산업적, 사회 문화적 측면의 필요성을 바탕으로 본 연구는 연기 음식 냄새 저감 성능이 뛰어난 친환경 저에너지의 가열조리 기구 개발 및 국내외 현장적용 산업화 모델 구축을 통해 한식당 시설 개선 및 고급화를 유도하고 세계시장에서의 한식문화 경쟁력을 확보코자 한식문화 경쟁력 확보와 경제, 문화, 산업적 성공 비즈니스 모델을 제시하였다.

This study is an analysis of the design changes of children's play facilities and the related rules and regulations which causes these changes. Accordingly, it is noticed that a site's change of design by legislation and by yearly alternation influences playground design. First, after revising the provisions for the distance from roads and parking lots, the constructing of safety fences between play facilities and the using of durable materials, alterations of the designs have been made a reality. Second, the design changes after the period of regulation transitions were caused by provisions related to the shelter of evergreens and conditions of the sun. Third, the changes of the playgrounds were related to the substitution of exercise facilities for the local residents and in carrying out a hygiene exam more than twice a year. Because a lack of regulatory standards for the design of playgrounds resulted in compliance based on individual interpretation and because a substitution of exercise facilities is part of the way to alleviate these regulations, the conditions of the site under investigation could be projeced. By such changes of regulations and analysis of alterations of playground design, programs for improvement were suggested. It turned out that the composition of the concrete standard in conformity with regulations required closer observance. Moreover, design standards for children's playgrounds are needed, such as the provision of variation in external appearance, the creation of more flexible layouts and the outlining of spaces by themes.

This study was conducted to select leaf vegetables suitable for cultivation in apartment verandas and simple and easy fertigation method for home gardening. In order to develop the convenient fertigation method, hydroponics, wick irrigation, and overhead irrigation methods were compared. For the wick irrigation, two types of nutrient sources were used; one was slow release fertilizers mixed with medium and the other one was nutrient solution filled in container located under pots. The growth of leafy lettuce, leaf mustard, and leaf beet was better in both of the wick irrigation methods rather than in overhead irrigation and hydroponics. The wick irrigation method is very easy, so that it is expected to bring a good result from the cultivating and managing point of view, if it brings with commercialized system along with slow release fertilizer. As a result of investigation of environment such as temperature, relative humidity, and irradiance level in apartment verandas in autumn the highest irradiance level during a day was just 48% and 35% in verandas facing south and feeing southeast, respectively, comparing to that in greenhouse. The light environment was investigated as a limiting factor for vegetable growing in verandas. Therefore, to select the vegetables showing good growth under low irradiance environment, nine leaf vegetables such as romaine lettuce, lent lettuce, head lettuce, endive, pak-choi, leaf mustard, garland chrysanthemum, leaf beet, and Chinese chive were grown under 0%, 50%, 70%, 90% shading. Among them, Chinese chive showed the best growth under low irradiance levels. Endive showed line growth reduction according to shading degree, however, even under 90% shading condition, it showed good growth. And then leafy lettuce, garland chrysanthemum, and pak-choi followed. Therefore, these results will be of help in selecting vegetables for veranda gardening with different light levels.
