This study was undertaken to assess eating habits and food consumption pattern of 365 adolescent girls in Kwangju area. Subjects were divided into 3 groups based on relative body weight as obesity index. Anthropometric data showed that mean height and weight were $161.9{\pm}19.0cm$ and $53.3{\pm}7.2kg$ respectively which are similar to those in the Korean Standard Growth data. Mean BMI and relative body weight were 20.50 and 97.1%. Age of menarche in the subjects significantly influenced the obesity index. Food habit score in the underweight group was significantly lower than that in the normal group at ${\alpha}=0.2$ level by multiple range test. Obesity was significantly associated with more frequent and irregular eating. It seems that students in the obese group were concerned on their body weight and tended to consume much vegetable. Obese group consumed more fruits, less butter and fruit juice compared to other groups. It might be suggested that more effective nutrition program might be developed and implemented to ensure good food habit of adolescent girls including obese as well as underweight group.

In the past the pattern of business down-trend usually appeared in the form of, first, decrease in facility investment, then decrease in inventory level, followed by reduced level of consumption. But the pattern nowadays is becoming just the opposite, that is, first, consumption decrease, then inventory level increase, followed by restriction of facility investment. Also in the past, the greater effort was placed in strengthening of hardware areas through optimization and modernization of production means on the premise of sales. But lately software areas take most of the main effort to establish production mean with sales as its objective. Under these circumstances one of the real problems facing production activities today is the conflicting relationship between sales and production functions. This occurs due to differences of their view points. Then, in order to achieve maximum profit at the least cost, which is the ultimate objective of a production activity, the need arises to effectively coordinate sales demand and plant production capacity. For this purpose strong control means and function must be devised. In our case study example we illustrate a management technique for a combined planning function, of optimal coordination of product mixes utilizing a computerized linear programming model as control means of attaining maximum profit. It is hoped that this example help achieve some of corporate objectives.

Purpose: Ground source heat pump system has been attracted in the horticulture industry for the reduction of energy costs and the increasing of farm income. Even though it has higher initial costs, if it uses in combination with heat storage, it is able to reduce the initial costs and operate efficiently. In order to have significant effect of heat storage type ground source heat pump system, it is required to design the capacity considering various conditions such as energy load pattern and operating schedule. Method: In this study, we have designed heat storage type ground source heat pump system in 5 cases by the operating schedule, and examined the system to find the most economic and having superb performance regarding the system COP(Coefficient of Performance) and energy consumption, using dynamic energy simulation, TRNSYS 17. Result: Conventional ground source heat pump system has lower energy consumption than heat storage type, but following the result of LCC(Life Cycle Cost) analysis, the heat storage type was more economic due to the initial costs. In addition, it has the most efficient performance and energy costs in the case of the smallest heat storage time.

The suwey on the consumption pattern of Korean traditional soy sauce and commercial soy sauce was performed. 55.8 percentage of surveyed house makes Korean traditional soy sauce domestically, But its frequency in actual use is lower than commercial soy sauce. The use of Korean traditional soy sauce and commercial soy sauce was different depending on the kinds of food. Korean traditional soy sauce is mainly used for kinds of soup, and commercial soy sauce is predominantly used for hard-boiled foods and Chapchae. Korean traditional soy sauce is known as our typical fermented food and has special flavor. But its main factors of special flavor were not well established yet. So the authors have investigated the main components of Korean traditional soy sauce for its typical taste. Five samples o$.$ere selected from'Kyung-ln'area. The sensory charac teristics of Korean traditional soy sauce itself were very different with that of cooked food added with Korean traditional soy sauce. The hard-boiled mackerel cooked with commercial soy sauce was prefered than Korean traditional soy sauce. And soups and seasoned vegetables cooked with Korean traditional soy sauce were profered. By stepwiEe regression analysis and correlation analysis, sensory overall acceptability mainly depends on specific gravity, salt content and amino nitrogen content (R'=0.94). And total nitrogen content was highly coirelated with overall acceptability (r=0.91).

This study was carried out to investigate the information concerning dietary patterns and analysis of the various factors that influence obesity. The subjects of this study were 1,020 middle and high school students in Seoul. Subjects were classified into under weight, normal weight and over weight group by body mass index. We investigated eating habits, life habits, food behavior and food consumption. Data were collected by questionnair and analysed with the SAS program. The results of this study way are summarized and concluded as fellows; In the case of dietary pattern, over weight group showed significantly higher in skipping a meal than the other group. Also over weight group tend to eat fast. There were significant differences of food intake frequency score by body mass index. From the results of factor analysis of variable related to obesity, 4 factors were generated and the factors were named 'Food behavior related to obesity', 'Snack consumption pattern', 'Life habit', 'Family environment related to food habit'. These factors were associated with obesity. To maintain nutritional balance and health, we should implement to ensure good dietary patterns.

Regarding demand response (DR) by residential users (R-users), the users try to reduce electricity costs by adjusting their power consumption in response to the time-varying price. However, their power consumption may be affected not only by the price, but also by user convenience for using appliances. This paper proposes a methodology for appliance scheduling (AS) that considers the user convenience based on historical data. The usage pattern for appliances is first modeled applying the copula function or clustering method to evaluate user convenience. As the modeling results, the comfort distribution or representative scenarios are obtained, and then used to formulate a discomfort index (DI) to assess the degree of the user convenience. An AS optimization problem is formulated in terms of cost and DI. In the case study, various AS tasks are performed depending on the weights for cost and DI. The results show that user convenience has significant impacts on AS. The proposed methodology can contribute to induce more DR participation from R-users by reflecting properly user convenience to AS problem.

Interest in fruit and vegetables has increased due to changes in consumer consumption patterns, socioeconomic status, and family structure. This study determined the factors influencing the demand for fruit and vegetables (strawberries, paprika, tomatoes and cherry tomatoes) using a panel of Rural Development Administration household-level purchases from 2010 to 2018 and compared the ability to the prediction performance. An artificial neural network model was constructed, linking household characteristics with final food expenditure. Comparing the analysis results of the artificial neural network with the results of the panel model showed that the artificial neural network accurately predicted the pattern of the consumer panel data rather than the fixed effect model. In addition, the prediction for strawberries was found to be heavily affected by the number of families, retail places and income, while the prediction for paprika was largely affected by income, age and retail conditions. In the case of the prediction for tomatoes, they were greatly affected by age, income and place of purchase, and the prediction for cherry tomatoes was found to be affected by age, number of families and retail conditions. Therefore, a more accurate analysis of the consumer consumption pattern was possible through the artificial neural network model, which could be used as basic data for decision making.
