Consumption of edible oil at food service institutions in Inchon was surveyed to provide basic data for continuous education of dietitians. Manufacturing industry was the major food service institution(78.8%) in Inchon followed by schools, hospitals and social welfare service centers. Most dietitians were at the age of twenties and college graduates with professional careers of 1-5 years. Oil was purchased on the basis of its quality within 1-3% of total food costs four times a month. Proper frying temperature was determined by dropping salt or food coating materials into the oil. Soybean oil was the most frequently used and commercial frying mix powder and flour and eggs in water were the most common food coating materials. Fish and commercial frozen foods were the most frequently used materials for frying. Fried foods were stored with covers in a basket and consumed within 30 minutes after cooking. Frying oils were used one more time after filtering and color was the index for determination of re-use.

When the energy resource available to a particular plant (be it coal, oil, gas, water, or nuclear fuel) is a limiting factor in the operation of the plant, the entire economic dispatch calculation must be done differently. Each economic dispatch calculation must account for what happened before and what will happen in the future. This paper presents a formulation and a solution method for the optimization problem with a fuel constraint in a competitive electricity market. Take-or- Pay (TOP) contract for an energy resource is the typical constraint as a limiting factor. Two approaches are proposed in this paper for modeling the dispatch calculation in a market mechanism. The approaches differ in the subject who considers and inserts the fuel-constraint into its optimization problem. Market operator and each power producer having a TOP contract are assumed as such subjects. The two approaches are compared from the viewpoint of profits. surplus. and social welfare on the basis of Nash Equilibrium.

The purpose of this study is to research the actual condition of environment and management of outdoor play at child care centers in Seoul, and to present a planning guideline for outdoor play environment. For this purpose, data were collected by a structured questionnaire and subjects were 164 directors of child care centers located in Seoul. The contents of the questionnaire were composed of general facts about the respondent and facility, environmental condition, managerial condition, and director's understanding about outdoor play. The data were then analyzed using the frequency, percentage, mean and crosstab. The major results have shown the following: 1) Most child care centers in Seoul had some space for outdoor play. 62% of them used front yard and 11 % a rooftop. 2) The space usually included fixed play instruments such as slide and complex unit structures, sand play area, and open area. It also had many natural elements as shrubs and earth. 3) 78% of the centers had a schedule for outdoor play. The schedule operates flexibly according to each center's own day schedule. Generally, a time for outdoor play was 21 to 30 minutes. 4) The directors of child care centers thought highly of outdoor play for it contributes to the balanced development of children. They answered that equipments and spaces, program devices, and teacher's understanding are some of the important factors for active outdoor play. 5) Most of them wanted wood-working area (construction activity area), water play area, and cages.

Recently, large APT complexes are newly constructed in Taegu city and among them, large APT complexes aggegate densly espically in Weolsung and Jisan complexes of Dalsuh-gu and Susung-gu districts. The purpose of this thesis is to perform occupants' apprasials about residential environment on the housewifes residing at new constructed APT who seem tn have different apprasials on the residential environment by the zones. The results of the investigations are as follows. 1. House possessed type and house sire got elevated in comparison with them before shifting residence in respect to residential property and it was revealed they moved to short distance in the change of their lands. And most occupants could choose their houses by looting-out and there's some difference in the choice motive according to the zones. 2. As a result of studying the relation between demographic and residential properties, there were deep differe-nces in the Possessed house type before move, possessed house size after move, preferenti-al degree of house and move plan. 3. In the degree of satisfaction on residential environment, the result was high in the order of heating facilities, water-supply and draining facilities and lighting and was low in the order of room's size, interior decoration and soundproofin. According to zones, there was a great difference in the items of room's size, privacy, heating facilities, securi-ty from calamity, ventilation, convenience of traffic and school group and facilities for extracurricular activities and the degree of satisfaction was high in Jisan zone in othe items except for room's size and heating facilities. 4. In the tenants' apprasials on tile inside and outside spaces of the zones, important factors were "Cultural Institutions", "Green Areas", "Level of Welfare Facilities" and "Utility degree of welfare facilities" and in the classification of important factors according to the zones, the first and the third factors were changed each other. I think this is because they attached importance to somethings dissatisfied in present circumstances.

The effects of seasonal differences and crating densities on the preslaughter losses, breast meat quality, and physiological indices of broilers were determined. A total of 600 broilers aged 35 days were divided into 10 treatment groups based on five crating densities (10.3, 11.5, 12.8, 14.1, 15.4 birds·m^-2) with two seasons (i.e., summer and winter) to give six replicates and were placed at various locations in the truck. The birds were transported in crates having dimensions of 1.0 m × 0.78 m × 0.26 m. The transportation distance was 20 km for 40 minutes (average 30 - 50 km·h^-1) during the early morning. The results revealed that broilers transported at densities of 14.1 and 15.4 birds·m^-2 recorded lower (p < 0.05) pH, water-holding capacity (WHC), and muscle redness compared to those at densities of 11.5 birds·m^-2. Furthermore, higher (p < 0.05) cooking loss was found in birds stocked at more than 14.1 birds·m^-2 compared to the other treatments. However, no effect (p > 0.05) with different crating densities on body weight loss, carcass traits, glucose, lactate, or muscle yellowness was observed. Crating density of 14.1 birds·m^-2 showed lower (p < 0.05) cortisol contents compared with birds at 10.3 and 15.4 birds·m^-2. Winter transportation had higher (p < 0.05) relative breast meat weight, cooking loss, muscle redness, and cortisol contents whereas summer transportation had higher (p < 0.05) glucose and lactate contents in the blood plasma of broilers. In conclusion, the stocking of 12.8 birds·m^-2 is recommended to minimize stress responses and undesirable changes that could negatively affect muscle quality.
