This study was undertaken to investigate the current meal management situation and behaviors of the housewives in Seoul during the period January in 1933. The aim of this study was to improve meal managenment in 1980. This study has been performed by questionnaire about kitchen forms, cooking machines. foodstuffs buying forms, plan of the price in meal and meal management behaviors. 1. 85% of the housewives had stand-up fashioned kitchen forms, and they were equipped with variety of cooking machines and high possession percentage that. 2. 66.7% of the housewives spent the price of meal under plan, 3.1% of them purchased foodstuffs daily. 3. The time spent in preparing the table of breakfast and lunch was about 60 minutes and dinner was about 90 minutes. the time spent in clearing the table of breakfast and lunch was about 20 minutes and dinner was about 40 minutes. 4. The numbers of daily cooking rice was the higher percentage twice a day than once a day, but increased higher percentage once a day than 1980's. 5. In preparing kimchi most of housewives were making it in their homes and number of making kimchi once a 15day and a month was high percentage. 6. When they prepared meals they gave higher percentage to the tastes of families than nutrition. The number of preparing a side dish in breakfast and lunch was 3~4, and dinner was 5~6. 7. In most cases housewives cooked for themselves, and the number of husbands who help their wives for kitchen work was increased in group of younger housewives than older. 8.

Two-spotted spider mite (TSSM), Tetranychus urticae Koch (Acari: Tetranychidae) is one of the major pests in apple orchards. TSSM was known to show different population dynamics depending on apple cultivars. We tested the host plant preference and fitness of TSSM on the leaves of 3 apple cultivars, Fuji, Tsugaru, and Hongro. TSSM showed higher behavioral preference to Fuji than Tsugaru and Hongro, and showed a higher fecundity in Fuji. The immature development of this mite was the shortest in Fuji and longest in Hongro. Total fecundities were not significantly different among cultivars, but daily fecundity was higher and longevity was lower in Fuji. Hongro was the less preferred cultivar for TSSM, and showed the lowest fitness by life table parameters. These results could explain the possible mechanisms of differential population dynamics among apple cultivars. Further study including diverse apple cultivars currently available in Korea could help to deploy time- and cultivar- specific IPM tactics.

Recently, the consideration of eco-friendly technology to reduce greenhouse gas is being emphasized in the aviation field. Various studies for applying electro-mechanical actuators that control mechanical linear and rotational movements using electricity as the primary power source are in progress. In this study, the fatigue analysis of the electro-mechanical actuator for the front wheel steering of a single aisle aircraft was carried out. A unit load stress table was constructed for the vulnerable part selected through structural analysis, and the representative stress for each load profile was calculated using the unit load stress table constructed for the vulnerable part. Then, individual profiles of representative stress group were extracted from continuous load profiles by applying the rainflow counting method. The damage of each profile was calculated by applying the S-N diagram. Finally, the total damage in the vulnerable parts was calculated by the linear cumulative damage law, and the fatigue life of the electro-mechanical actuator for the front wheel steering of a single aisle aircraft was evaluated.

The rapid increase in apartments of Korea brought about overall changes in the life style, and definitely played the biggest role to convert into western style. Since 1960, furniture has been changed for 50 years along with apartments, but furniture companies and the academic world had insufficient historical materials and lack of study. In addition, considering the changing trend according to residents' life style, the data of furniture industries should be collected to study every year or in 5 years at least. Therefore, this study aims to provide basic data that gives historical materials or design clues based on recent AV equipment-oriented storage furniture in the living room that prioritized design in public space. Accordingly, the study looked into the periodical trends of Korean furniture industries, analyzed 10 furniture companies in Korea which is actively doing business as the sample and arranged key points of periodical changes of furniture in the table, and suggested the conclusion according to the image map, style, color, material, and function.

This study discusses the traditional main life culture of Korea and the relations with the traditional manners of Korean culture. According to studies of literature and an analysis, it shows the traditional courtesy can be linked to the housing structure of the Cho-sun dynasty which can be termed as a representation of traditional Korean society. Housing culture of Cho-sun dynasty led to a most characteristic living culture. To be specific sit-down culture use norms, hierarchy and fittings can be sited. The sit-down culture in turn led to the main courtesies of greeting, table manners, etiquette for entrance and exit, the carefulness shown to elders, the self-restraint of speech and action and the manners between men and women, But in today's world there are realistic difficulties that make the application of these norms in everyday life difficult. But at the same time we must realize that there are traditional norms which overcome time and which affect today's norms.

Rural policies in Korea have been changed into amenity-oriented ones recently to enhance the quality of life for villigians, which should be supported by the amenity-oriented maintenance system for rural space or environment too. Although so many studies on the classification system of amenity resources had been carried out, few ones which classified them principally by their spatial characteristics had been tried. From the viewpoint mentioned above, this study tried to propose a tentative classification system of amenity resources focussed on their locational characteristics. By the literature review, its draft was prepared, and after 2-round expert checks, the final table determined, which composed of 3-subsystems; green, production and living environment. Through the field application works in two case villages, its practical applicability was ascertained, from which two regarding points were found; public usability of terms and seasonality of amenity resources, especially green ones.
