Despite the steady effort of kitchen furniture industry, consumers' complains never seem to decrease. The common storage problem of the houses of different sizes(20 pyeong, 30 pyeong, and 40 pyeong) was the dificiency of storage area and inadequate shelf division. It implies that such dificiency in kitchens is not because of the size of storage area, but because of such a great diversity of kitchenware and lack of studies on these items. The purpose of this research is to provide the checklist of the variety and quantity of stored kitchenware in researched area and easily adopt it to the kitchen furniture design. Studied household in average hold 239 types and about 890 items. The size of residence did not effect the number much. The first step of making the checklist is to categorize items into 9 biggest categories considering the usage of items and in which step of the preparing food the item was used. Second step is to categorize the items into 31 smaller categories reflecting the shape of items, the storage style and the place of storage. Third step is to sort the items into smallest categories by the frequency of use, storage type, and additional capacity of an item. Even when items are sorted into the same higher level of categories, the frequency of use caused storage area to differ. Also, storage style of an item differed according to the storage area. Based on these factors, we listed items in detail and made the checklist.

An aqueous solution of a commercial liquid synthetic detergent for kitchen use was photodecomposed in the presence of titanium dioxides powder under an atmosphere of air at room temperature. Titanium dioxides were prepared by sol-gel method from titanium iso-propoxide at different R ratio($H_2O$/titanium iso-propoxide) and calcined at $500^{\circ}C$. All titanium dioxides were characterized by XRD, BET surface area analyzer and UV-VIS spectrometer. The surface area of titanium dioxides prepared at R ratio=6 appeared higher volume about 20% than commercial $TiO_2$ catalysts. XRD patterns of titania particles were observed mixing phase together with rutile and anatase type. Titanium dioxides prepared by sol-gel method show higher activity about 6% than commercial $TiO_2$ catalysts on the photocatalytic degradation of a commercial liquid synthetic detergent for kitchen. The concentration of the detergent decreased to about 90% of its initial value at illumination times of 2 hour. Illumination for 30 minutes decreased the concentration of oxygen to about one-fifth of the initial value.

This study was carried out to investigate foodservice management of child care centers in Ansan and to suggest the basic data for foodservice management improvement. A questionnaire survey of 48 child care centers in Ansan was undertaken. Child care centers were categorized large (children eve. 100) and small(children less than 100) by size and public and private by type. Survey questionnaires consisted of general background, employee, food inspection and storage, kitchen, cooking facilities, food distribution and hygiene utensils. The results of this study are summarized as follows: because 46.9% to 56.3% of the centers took a dietitian in employment, foodservices in most of centers were not managed by professionals. The average of employee were 0.77 persons in smalll centers and 1.65 persons in large centers. The average space of kitchen were 3.86 pyung in smalll center, 6.06 pyung (1 pyung=$3.3058m^2$) in large centers. According to the data analyzed from Food inspection and storage, kitchen, cooking facilities, food distribution and hygiene utensils, the results indicate that the foodservice management of child care centers were in a relatively poor state. The director in child care centers should recognize the importance of the sanitation management and pay more attention to food service facilities. To improve foodservice performance at child care centers, it is required fur the Ministry of Gender Equality and Family to develop both the kitchen facility model based on the general sanitation standards and guidelines for child care centers.

The purpose of this study is to suggest the improvement strategies for exhaust performance in composite kitchen hoods. The Exhaust only hood, the 2-way compensating hood and the 3-way compensating hood were selected, and the laboratory experiments were performed to compare the local exhaust efficiency and the indoor temperature distributions according to the variations of the hood type and supply/exhaust air velocity. The results of this study can be summarized as follows. The compensating hood has better performance than exhaust only hood in the aspect of local exhaust efficiency and temperature distribution. The 3-way compensating hood shows the best performance when the supply air velocity is about 2.7 m/s, and the 2-way compensating hood at the supply air velocity of 3.5 w/s. In the same exhaust rate condition, if the exhaust area of the hood is increased and therefore the exhaust velocity is lowered, the supply air velocity is also lowered to get the optimum performance. The optimum exhaust velocity range of the commercial kitchen hood which derived from this study is 0.48 ∼ 0.55 m/s.

Cooking oil in kitchen-fog is the most harmful factor to the health of a cook. The proposed filter is a tool that protects the cooked state, to prevent users from inhaling oil mist in the kitchen. Due to efficiency issues, existing filters are of the mesh type or baffle type. In this paper, CFD analysis is carried out to select a filter with low pressure loss and low efficiency, and to attach the sub-filter to improve efficiency. The results of the analysis on the collection efficiency and pressure loss of three sub-filters, i.e., circle type, droplet type, and cone type, showed that the collection efficiency was 64.09% and the pressure loss was 1.26 mmAq when the circle type sub-filter was applied. The position of the sub-filter showed the best efficiency and pressure loss when it was located at the bottom of the center of the gap of the main filter.

본 연구는 노인주거시설 단위주호의 부엌을 대상으로 하여 사용 실태 및 거주자의 요구를 조사한 것이다. 지금까지의 노인주거에 관한 연구를 보면, 포괄적이고 대안적이어서 자세한 차원의 노인주거생활에 대한 연구로는 부족했다. 그러므로 노인에게 적합한 한국형 노인주거의 부엌 계획을 개시하고자 한다. 이에 따라, 우리는 대표적인 노인시설 4곳을 직접 방문하여, 독립적으로 또는 공동으로 시설에 거주하는 65세 이상 건강한 노인을 대상으로 하여 조사가 진행되었다. 4개의 시설에 각각 2단위주호를 방문하여 총 8개의 부엌을 조사 하였고,조사대상자의 단위주호의 공간계획과 부엌가구의 디자인을 살펴보고, 실측하였으며 또한, 조사대상자의 만족과 선호 그리고 부엌사용에 관한 설문조사를 실시하였다. 조사한 결과, 시설에서 제공하는 식사서비스를 이용하는가에 따라 부엌의 이응정도와 사용방법 지 차이를 발견할 수 있었다. 식사서비스를 이용하는 거주자에게는 차나 다과의 준비를 위한 공간만이 필요함을 알 수 있었고 단위주호 내에서 직접 식사를 하는 거주자는 좀 더 큰 수납장과 다용도실이 추가적으로 필요하였다. 안전과 기능적인 측면으로는 잘 디자인되어 있었고, 대체로 세탁기는 부엌 수납장에 빌트인 되어 있었는데 대부분의 거주자들은 이 것에 만족하고 있었다. 본 연구결과 노인의 거주양상과 생활방식의 차이에 관한 연구를 통한 한국형 노인주거시설의 부엌 계획을 위한 기초자료로 활용되어지기를 기대한다.

The purpose of this study was to promote the utilization of wind velocity of kitchen and bathroom exhaust ducts for wind power generation in high-rise apartments. The research content can be summarized as follows: 1) Nine high-rise apartments were examined for the installation of kitchen and bathroom exhaust ducts located in the pipe shaft (PS) section. After selecting simulation candidates, a simulation was performed with the STAR-CCM+ Ver 5.06 program. 2) Of nine high-rise apartments, seven had kitchen and bathroom exhaust ducts, whose cross section was in the range of $0.16m^2{\sim}0.4m^2$. The area ratio between the exhaust ducts and PS section (cross section of exhaust duct/area of PS section ${\times}$ 100) was on average 3.2%. 3) The simulation results were analyzed. As a result, the smaller cross section kitchen and bathroom exhaust ducts had, the more advantages there were for increasing exhaust wind velocity. If an out air inlet duct is installed to the old kitchen and bathroom exhaust ducts, it will increase exhaust wind velocity by 3.01~3.98m/s and contribute to the proper wind velocity level (3.0m/s). 4) When the simultaneous usage rate between the kitchen and bathroom exhaust fan increased from 20% to 60%, exhaust wind velocity increased. The "entire house holds" condition for exhaust fan operation provided more even exhaust wind velocity than the "some house holds" condition. 5) Exhaust wind velocity increased in the order of amplified (T-3), induced (T-2) and vertical (T-1) top of kitchen and bathroom exhaust ducts. Of them, the amplified type (T-3) was under the least influence of external wind velocity and thus the most proper for kitchen and bathroom exhaust duct tops.
