This study has found out appropriate scopes of correlated color temperature and illuminance value with regard to general diffused lighting and work in the kitchen. It also has presented appropriate photometric quantity control speed for behavioral change with the following results. 1)For general diffused lighting, the appropriate photometric quantity has turned out to be 4,000 to 4,500K in color temperature and illuminance value of 300 to 400lx. And 300lx at 4,500K has proven to be the most comfortable, behavior-appropriate, and preferred pair. 2)As far as appropriate photometric quantity for work is concerned, color temperature of 4,000 to 5,000K and illuminance value of 600 to 800lx are appropriate, while 700lx at 4,500 to 5,000K are the most comfortable, behavior-appropriate, and preferred set. 3)As for appropriate photometric quantity control speed in behavioral change, 3 to 5 seconds has proven the most comfortable, appropriate, and preferred for behavioral change from entry to general areas and 1 to 3 seconds for change from general to work.

This research was undertaken to compare basic bodice prototypes for Internet shopping customer, and to select a profitable fit vacant space quantity between clothing and body. A total one hundred of eighteen outfits (4 types of pattern ${\times}$ 9 subjects ${\times}$5 body areas) were constructed with basic bodice drafting method of Japan Bunka Women's University according to nine male body types. Fifty-two experts analysis of the different prototypes as five body area and evaluate the most appropriate ease amount and stabilization of the simulation images on the computer. The experiments with automated methods using simulation image are based on AZ program of TORAY, Japan. Data was analyzed using percentiles, frequency and $X^2$. Taken together, the present result of vacant space quantity and stability evaluation through images shows that there is a significant difference in the size variation of the chest circumference, shoulder slope and waist circumference. In case of ease amount, chest area, shoulder slope, waist area and armhole except neckline area were shown more appropriate on the basic bodice pattern without size change. In case of stabilization, the chest area, shoulder slope and armhole except waist area and neckline area was shown the best on the basic bodice pattern without size change. However the waist area was shown on the basic bodice pattern plus 2 cm, neckline was shown more appropriate on the basic bodice pattern plus 1cm.

Customary agriculture seeks to increase production and supply people with safe foods. Thus. the promotion and establishment of organic agriculture are required to reduce water and soil pollution caused by customary agriculture. Although organic agriculture is an agricultural technology system whose basic principle is organic water circulation in agronomic agriculture and livestock industry. the livestock raising sector has not been developed in Korean organic agriculture: hence the limited development of agronomic agriculture. This study therefore sought to develop a standardized model connected with organic livestock raising and organic agronomic agriculture to secure symmetric and continued development. Specifically, this study reviewed the technological and economic problems related to the development of a naturally circular standard model where organic agronomic agriculture and organic livestock raising are connected. Likewise, a model for calculating the appropriate quantity of fertilizers to be applied and appropriate number of livestock to be bred was proposed as important factors in the development of a regionally circular agriculture model, and an alternative to a system connecting the two factors suggested.

This study was focused on the system of regional resource circulation(RRC) of Asan-Si as a case region. So 301 farmers(members of producer organization) who are managing environmental-friendly agriculture (EFA) are surveyed. The RRC system is focused on establishing the system of regional complex farming connected with the seedling fanning and the livestock. The main results surveyed are as follows : First, total cultivated acreage is 574ha. Second, the total quantity of by-products of rices, beans, wheats is 983M/T. Third, the total quantity of nutrient requirement for seeding fanning is 85,335.6kg This research shows how to develop the RRC system for EFA. The development model and strategies are as follows : The first model for the system of regional resource circulation can be called the scenario of the best output for the system of environmentally friendly resource circulation. It is considered to estimate the appropriate number of heads of Korean cattle and hen which can be bred simultaneously. And the second model can be called the scenario of the regional allotment for the appropriate number of heads of those. It is considered to estimate the appropriate number of heads of those which can be alloted by the individual farm or area.

Purpose : This study carried out to develop the questionnaires that can measure objectively menstrual quantity and determine quantity index. Method : First, we made questionnaires to measure menstrual quantity by six question. Then we investigated 1309 women's questionnaires who has the menses. Conclusion : 1. the questionnaires that can measure objectively menstrual quantity and determine quantity index was high a correlation coefficient therefore those were used Method of Menstrual Quantity(here after MMQ) calculation. Those were added and averaged. 2. We examined correlation of calculated MMQ and women's questionnaires who has the menses therefore we got 0.30~0.47 correlation. 3. MMQ 1~3(hypomenorrhea) was 39 persons 3.19%, MMQ 4~6(normal menorrhea) was 1050 persons 85.85% and MMQ 7~10(hypermenorrhea) was 134 persons 10.96%. MMQ 4 tended to be little and MMQ 6 tended to be much. 4. MMQ confidence was high as 82% comparatively so we thought MMQ was appropriate as the measured method of menstrual quantity.

Bearing friction and disturbance are the important parameters in control spacecraft using reaction wheel. In this paper, those parameters are estimated by preload and oil quantity. In order to determine the bearing preload's impact on performance, measure the disturbance and the bearing friction coefficient with increasing the preload to the allowed amount. And, find the relationship between oil quantity and bearing friction coefficient, measure it with increasing the oil amount in the bearing. With these results as a reference, find the appropriate amount of preload and oil quantity.

This paper presents an advanced energy saving algorithm in building. It is important to aggregate a various demand side resource which is surely controllable at the peak power time to reduce the energy cost. Previous demand side algorithm appropriate for building is based on peak power. In this paper, we develop the new energy saving algorithm to reduce the quantity of power consumption. The simulation results show that the proposed tem is very effective.

In this paper, the quantity of dot gain in off-set printing is estimated by using the method of UCR(under color removal) and GCR(gray component replacement) and the degree of dot gain is researched through measurement of dot coverage of each color patch at the output film that is variously applied to discretionary quantity of dot gain each line in screen in the printing for the process of color separation and at the offset printing. Also, the best appropriate quantity of dot gain treatment is examined by printing each line in screen for reproduction of colors.
