The purpose of this study is, to examine current foodservice management practices at free meal service organization for elderly people and, to evaluate the attitude of recipients about the service and their ecological background. 6 meal service center as well as randomly selected 120 recipients at Sungnam area were surveyed and interviewed and result were summarized as follow. The cost of each meal (lunch) was ranged from 1,300 won to 1,500 won and number of attendant at meal service were ranged from 50 to 200 persons. Meal time for lunch begins from 10:30 am to noon because greater portion of people (elderly) didn't take breakfast frequently. Most of the center adapted self-service system. Standard recipe was not developed and meal preparation was controlled under the experiences of volunteer’s. Recording system of, nutrition management, production control, storage and inventory control was not well adapted by most of the center. In order to measure the level of storage, sanitation etc., scorin system in survey was adapted in this study and result are as follow: The score of sanitation of kitchen was lower than dinning area and that of food storage was lowest score. It was suggested that not only financial but also systematical support on management by local government may be necessary to meet the goal of supply nutritionally balanced food at the center. The score given by the recipient on the satisfaction of meal service was rate as 4.8 at the 5-point maximum scale. Meeting friends and share social relationship was major reason (41.6% of the total) of visiting to the center. It is suggested that in order to meet the changes of the patterns of change of social and family structure, the service of the center should be extended in urban area and it is necessary to develop systematic management models for the center.

$\beta$-1,4-Mannotriose was prepared b he enzymatic hydrolysis of white copra meal (WCM) and the subsequent elimination of monosaccharides from the resultant hydrolysate with a yeast. The enzyme system from sunflower seed hydrolyzed WCM and produced monosaccharides and $\beta$-1,4-mannotriose without other oligomers at the final stage of the reaction. WCM(50g) was hydrolyzed at 5$0^{\circ}C$ and pH 4.5 for 24 hr with crude enzyme solution (500 mL) from sunflower seed. By the elimination of monosaccharides from the hydrolysis products with a yeast (Candida glaebosa), 8.1 g of crystalline mannotriose was obtained without the use of chromatographic techniques. After 48hr of yeast cultivation, the total sugar content decreased from 4.6% to 3.5%, whereas the average degree of polymerization increased from 2.3 to 3.1.

Total phosphorus contents in rice bran and soybean meal were determined to be 5.81 and $2.77\%$, respectively, and $97.2\%$ of phosphorus in rice bran and $66.4\%$ in soybean meal were presented as phytate phosphorus. Optimum pH condition for hydrolysis of phytate in rice bran and soybean was determined to be in the pH range of 3.7 and 5.3. The highest activity of phytase for hydrolysis of phytate in both samples was determined to be at $55^{\circ}C$ for rice bran and $55-60^{\circ}C$ for soybean. Hydrolysis of phytate in soybean meal at pH 5.0 increased with the co-reaction or consecutive reaction with protease; however, in rice bran hydrolysis decreased with co-reaction with protease. Phytate degradation of soybean meal in the presence of pepsin at pH 2.5 showed higher than that of rice bran. Phytate degradation of rice bran in the presence of trypsin or pancreatin at pH 7.0 increased the activity around 2-times compared with the activity in the absence of trypsin or pancreatin. The results of this study suggest that hydrolysis of phytate in rice bran or soybean meal with phytase and protease may provide an alternative process for the preparation of aquacultural feed with a low level of organic phosphorus.

이 연구는 남성들의 은퇴가 활발히 일어나는 연령층 부부들의 식사 및 관련 행위를 분석하고 있다. 이 연구는 가사노동을 다루어 온 많은 연구들과 중첩되는 측면이 있으나, 식사준비, 식사행위, 설거지 등의 개별항목을 끼니별로 접근함으로써 일상적인 삶의 구체적인 모습에 한걸음 더 다가가고 있다. 한편, 대부분의 기존연구와는 달리 개인의 특성과 함께 부부나 배우자의 특성을 함께 고려하여 분석을 시도하고 있다. 한국통계청이 실시한 2004년도 생활시간조사자료 중 40대 후반부터 60대 후반 사이의 기혼여성들과 그 배우자들의 식생활행위를 분석해 본 결과, 부부의 식사행위, 식사준비 및 설거지 양상 등은 무엇보다도 부부의 취업형태에 따라 큰 차이를 보인다. 부부의 취업형태를 중심으로 볼 때, 부부가 함께 식사하는 비율이 가장 낮은 것은 부인만 취업한 상태이다. 은퇴연령층에서 부인만 취업하고 있다는 것은 이들이 식당 등과 같은 서비스업에 종사할 가능성이 높으며, 이로 인해 부부가 함께 식사할 수 있는 기회가 적음을 의미한다. 한편, 부인만 식사준비 하는 비율은 부인만 취업한 경우가 다른 경우보다 낮게 나타난다. 그럼에도 불구하고 부인만 취업한 경우에도 부인만 식사를 준비하는 사례가 절반 정도에 이른다. 부인만 설거지를 하는 비율 또한 식사준비를 하는 비율의 패턴과 유사하다. 이 비율 또한 부인만 취업한 경우에 가장 낮지만, 상당 수준에 이른다. 이를 통해 볼 때 식사준비와 설거지를 하는 해당 연령층 부인들의 비율은 취업상태에 따라 분명한 차이를 보이지만 대체로 이들 행위들은 여성들의 몫으로 남겨져 있다. 이는 다시 가족 내 식사준비와 설거지 등과 같은 일상적인 삶의 행위가 가족내 성역할을 반영하고 있음을 보여준다.

The purpose of the study was to examine the effect of sex role orientation on the amount of time spent in meal preparation and cleanup, clothing care, and indoor cleaning accomplished by husbands and wives in couple-headed households in the U.S.. The overall research hypotheses examined were : (1) there is a relationship between demographic and socioeconomic characteristics of the husband and wife and the sex role orientation of the husband and wife; (2) for both husbands and wives, there is a relationship between sex role orientation and the amount of household production time that is accomplised by each individual; and (3) the relationship between sex role orientation and the amount of household production time remains when demographic and socioeconomic factors are controlled. The 1981 data from the 1975-1981 Time Use Longitudinal Panel Study collected at the University of Michigan were used for this study. The major findings is that a relationship between sex role orientation and the amount of time spent in three household production activities was not found, when all independent variables were controlled. That is, sex activities was not found, when all independent variables were controlled. That is, sex role orientation was not a predictor affecting the amount of time that husbands and wives spend on meal preparation and cleanup, clothing care, and indoor cleaning.

A survey was made, from May to June 1991, to reveal the current situation of the meal management of the homemakers in Jeonbuk area. The results obtained from 464 homemakers were summerized as follows. The meal expenses were planned and managed mostly by the homemakers (93.3%). The 31.1% homemakers expended 200,000-300,000 Won a month for meals and the average expenditure was 294,106 Won. Among the homemakers who responded, the 34.0% managed their account books for meal expenses. With decreasing age(p<0.05), increasing education level (p<0.001), and increasing the income(p<0.01), the number of those who managed the account book tended to be higher. Usually they bought their foods at the market place (52.1%) and they did every other days(33.2%). The 46.9% planned what to buy and chose the best ones among the foods they planned to buy at the market. The percentage of those who prepared their menus planned in advance was only 5.5%. The most homemakers cooked for themselves (96.8%). On cooking and buying foods, the 48.2% considered their husbands first and the 64.4% regarded the tastes and needs of their families as the most important thing. The majority (66.2%) regarded the dinner as the most important among those three times of meals. The 39.6% prepared Kimchi twice a month. The foods they prepared for each meal were usually 4-5 kinds (43.2%). Mostly they prepared meals three times a day (49.1%). The average times spent in preparing and cleaning the tables for lunch and breakfast were 41.6, 96.2 minutes respectively. The homemakers who had jobs tended to spend less time in preparing and clearing the tables than those who had not (p<0.01, p<0.001). The 58.0% had complaints in that the food prices were too high and their moneys for meal preparation were insufficient and the 16.6% had difficulty in satisfying the tastes of their families.

The purpose of this study were to analyze work function and labor productivity in school foodservice systems through work sampling methodology. Conventional foodservice were classified into 5 group depending on the number of meals served. Commissary school foodservices were also classified into 5 group by cluster analysis using the number of meals served, the number of satellite schools, and the duration of time for delivery of food. Work measurement through work sampling methodology was conducted in at 5 conventional and 21 commissary food -services during 3 consecutive days from September to October in 1995. Results from work measurement through work sampling methodology were as followed : The most prevalent work functions was cleaning (26.5%) and then processing (25.1%) in conventional while it was processing (30.9%) and then cleaning(25.2%) in commissary school foodservice. Delay was 22.9% and 19.7% respectively. Mean labor minutes per meal of conventional and commissary foodservics were 4.57 and 4.09 minutes, respectively : no significant difference in labor minutes per meal existed between the two systems. but mean labor minutes per meal of commissary foodsevices(1.79min) was significantly lower than that of conventional foodservice(2.33min) during work time before service (p<0.05). Productivity was significantly lower in foodservices which served less than 400 servings ; n significant differences existed among 401-70, 701-1,100 and 1,101-1,500 meals. The highest productivity was in conventional school foodservices which served 1,501-1,900meals. Labor minutes per meal of commissary school foodservice which served less than 400meals per day was significantly lower than those of foodservice which served 401-1,900meals (p<0.05). Labor minutes per meal, preparation and cleaning were positively correlation in two school foodservice systems.
