The objective of the study is to conduct an empirical study on consumers' rice consumption behaviors and purchase activities. To achieve this objective, a case study on consumer households was conducted in Pusan during March 1992. 310 questionnaires collected were analyzed by tables and discrete regression models. The major findings of the research are as follows. 1. More than half of the consumers purchased the rice at least once a month from the traditional rice retailer. The quantity each purchase usually did not exceed 24㎏. It was found that a household owning a car or having more members directly purchased from the rural markets, farmers or the reliable relatives. Rice consumption was positively related with the size and the proportion of teenagers of a household, but negatively related with the education level and work status of the housewife. Without any standard or regular buying date, many consumers purchased the rice when they ran out of rice. Though 80% of the consumers surveyed wanted a small package of rice, only 10% of the consumers actually used to purchase in a small package. 2. Consumers had a strong preference to high-quality rice. A household with a highly-educated or aged housewife seemed to prefer to it than others. It was found that consumers were willing to pay more price to the clean or pollution-free rice. The price premium for the clean or pollution-free rice was positively related with the education level and the age of the housewife, and the income of the households. But the available information on the quality of the rice was quite limited to consumers. The only source of the information on the quality of rice for most consumers was the rice retailer, though it was widely believed that an illegal and unfair rice marketing was prevalent in the retail market. 3. Only 3.5% of the consumers surveyed had the experience of buying the government rice recently and 60% of consumers answered that the government rice was lower in quality than other rices. 11% of consumers surveyed recently bought the agricultural cooperative rice and most of them believed in the quality and the weight of the rice. The main reason that many consumers did not consume the agricultural cooperative rice seemed to be the less availability of the shops selling the rice around the household. Since 41.6% of the consumers surveyed would purchase the rice imported if it were cheaper and better in quality and they were especially interested in the quality of the rice, it seems to be very important to enhance the quality of the domestic rice varieties in order to compete with the imported rice. 4. Therefore, a rice marketing system for the distribution of high-quality rice should be developed to meet the changing rice consumption behavior. First, the government should reform the current purchase and release policy in order to establish the distribution system of high-quality rice. Second, agricultural cooperatives should play an active role in the establishment of grading and standardization of rice to prevent the illegal and unfair rice marketing. Third, rice retailing should be liberalized so that consumers easily purchase rice in a small package at the near-by shop. Fourth, the production of low-polluted rice should be encouraged and the quality certification system to guarantee the low pollution of rice needs to be devised.

This is the conclusion of the study on some nutritional salts included in the wastewaters and the sewages through 2 years, from 1986 to 1987. These are the wastewater being treated and discharged to the neighboring kwangyang Bay from the factories which are discharging the wastewater in the internal area of Yeochon Industrial Estate(Y.I.E), the sewage of Ssangbong area, the external area of Y.I.E, being discharged to the neighboring kamak Bay, the water treated by the night-soil treated plant in Yeosu city, the wastewater of Factory-H in this area and the sewage of the Yeondeung stream being flowed into Yeosu Harbor. 1. In Contents of PO_(4)-P and TKN in the wastewater being treated and discharged to the kwangyang Bay from 14 factories in Y.I.E the PO_(4)-P showed respectively 2.348mg/l at factory D and 2.020mg/l at factory A-I (main plant), and TKN showed 38.862mg/l and 71.337mg/l. These are the highest contents compared with the other factories. In the other factories, PO_(4)-P is 0.08-0.149mg/l and TKN is 0.350-11.994mg/l. 2. The ratio of treatment on PO_(4)-P and TKN by the current wastewater treatment is irregular and the average ratios of treatment in general show 85.4% in PO_(4)-P and 66.4% in TKN. 3. The loading amounts of the nutritional salts loaded the neighboring kwangyang Bay from the waste and treated waste of 14 factories in Y.L.E are 16.77kg/l, in PO_(4)-P and 484.46kg/l each when the water is originally wasted. 4. The contents of the nutritional salts in the Ssangbong sewage A and B of the external area Y.I.E discharged to kamak Bay, the treated water of the night-soil treated plant in Yeochnn city and the waste and treated water of factory-H in Yeosu are as follows. PO_(4)-P are 0.689mg/l, 1.085mg/l, 1.103mg/l and 0.0027mg/l in order and TKN are 15.654mg/l, 24.194mg/l, 28.675mg/l and 0.980mg/l. 5. The contents of PO_(4)-P and TKN in the Yeondeung stream which han an indirect influence on kamak Bay are 0.884mg/l and 15.234mg/l each, and the loading amounts by one day are 38.633kg and 665.756kg. 6. According to the measurement result, the entire area of kamak Bay close by the land also is the same. But the other areas belong to the Eutrophicated sea area.

The objective of this study is to investigate the methods to activate the rice marketing activities of agricultural cooperatives. For the objective, agricultural cooperatives and farm households in Kyungnam area and consumer households in Pusan area were sampled and surveyed during February and March 1992. Major findings of the study are summarized as follows : 1. Rice marketing activities of agricultural cooperatives were in a slump due to the low quality of rice, deterioration of competitiveness against the merchants, insufficient and old-fashioned rice milling facilities, deficiency of systematic rice sales through cooperatives, and lack of personnels specialized in the rice marketing. However, farmers seemed to favor the increased involvement of the agricultural cooperatives in the rice marketing. 2. The measures to activate the rice marketing activities of the agricultural cooperatives included: 1) agricultural cooperatives should participate in the price stabilization and the demand and supply adjustment functions monopolized by the government; 2) the rice processing complex should mainly be managed by the agricultural cooperatives; 3) labeling and product differentiation of rice should be implemented; 4) the agricultural cooperatives should participate in the rice price stabilization programmers; 5) co-ordinated rice marketing of the cooperatives should be activated and the number of rice-specific shops of agricultural cooperatives in the urban area should be increased; 6) the government intervention in the time and the quantity of the sale of rice marketed by agricultural cooperatives should be eliminated, 7) and finally the autonomous management of the agricultural cooperatives should be guaranteed so that business items and management system proper to the regions could be developed.

To investigate the differences of characteristics and attitudes between greenhouse-horticulture farms and non-greenhouse-horticulture farms, 276 farm households were randomly selected from the 10 farm villages with active greenhouse-horticulture farming, located in the eastern region of Kyungnam Province. Of them, 204 farms were doing greenhouse farming and 72 farms were not. Significant differences were found between greenhouse farms and the others. The operators of the greenhouse farms had relatively low average age and farm experience. But they had relatively high education. The ratio of woman and off-farm employment in the composition of operators wee higher in non-greenhouse farms. The greenhouse farms had more household members, larger farm size, more farm machinery and less livestock. Most of the differences of farm characteristics represent the labour condition of the farm. Not many non-greenhouse farms intend to begin greenhouse farming mainly because of labour and investment capital shortage. Very few greenhouse farms seem to enlarge their enhouse size in the near future. Non-greenhouse farms were relatively more optimistic bout the future of greenhouse-horticulture agriculture. The main reasons for greenhouse farms' pessimistic prospect were over-production and import liberalization of greenhouse-farming products.

Drilling tests were carried out austempered ductile cast iron(ADI) to clarify the factors influencing the drilling chracteristics of ADI material. The machinability of material was evaluated using high speed steel drill and cobalt contained drill of 6mm diameter. The spherodal graphite cast iron materials were austenized at 900℃ for in hour and then wear was kept at 375℃ for 2 hours. Austempered ductile cast iron contains a great deal of retained austenite which contributes to an improvement of impact strength. In this paper, machinability of ADI was investigated by drilling experimentation. The results obtained are as follows: a) Flank wear increases logarithmically with the increases of cutting time. b) Relation of flank wear and cutting force can be applied to FZ = 925VB + 820 for the cutting suggested condition. c) Drilling hole number of about 2 times can be reduced more step feed than ordinary feed due to the high hardness of ADI material and hardness increasing ascribed to the martensite of retained austenite.

The objective of this analysis is to conduct an empirical study on consumer's flower consumption behavior and purchase activities. To achieve this objective, a case study on consumer households was conducted in Pusan during March- June 1996. 387 questionnaires were analyzed by tables and Tobit Regression Model. The major findings of this research are as follows. 1. As the consumers surveyed didn't purchase flowers so often and didn't expend much money for consuming flowers, flower consumption was at a very low level. It was found that the flower demand had strong seasonal variation and more than half of the consumer usually bought flowers for making a gift and commemorating various events 2. Most of the consumers purchased flowers from traditional small size retailers. They had some difficulties in consuming flowers because there was no convenient flower shops in their neighborhood and they didn't know very well how to take care of flowers. 3. According to Tobit regression model, it was statistically significant that flower consumption was positively related with the experience of housewife about flower arrangement, the age of housewife and the household owing a car, but negatively related with the work status of the housewife. 4. Therefore, for expanding and stabilizing of flowers demand, flower marketing system should be improved. The flower retailing should be especially diversified so that flowers consumers easily purchase the various flowers at the near-by shop. The flower retailers should have much knowledges of taking care of flowers and flower arrangement. The flower cooperatives should play an active role in the establishment of information system to offer flower consumers not only the exact flower prices but also the methods of controlling flower and flowers arrangement.

The objective of this study is to analyze the present status of futures contract in Korea. Korea are taking part in 3 types of futures market: foreign futures market, KOSPI 200 stock index futures market of the Korea Stock Exchange(KSE), and the futures market of the Korea Futures Exchange (KOFEX). The futures contract trading volume in all the markets shows continuously increasing trend. Trading volume in foreign futures market realized 124 billions dollars in 1998, which were 7 times more than trading volume in 1993. The amount of KSE's KOSPI 200 stock index futures increased 9 times form 1996 to 1998. The KSE have moved into the top 10 exchanges in the world. The futures volumes in KOFEX amounted to 7,508 contracts a day on the average September 1999. The size of futures market, however, is still small relatively to spot market and there are many problems in Korea futures markets such as small scale of futures commission merchants, unfair trading in spot market, regulations, irrelevant acts, and low level of understanding about futures contract. To activate futures markets, it is necessary to exploit various new futures contracts which everyone can recognize easily, to improve futures trading system that is able to derive speculative investment, to strengthen public relations and education, and to establish competitive market system through relaxing regulations and restrictions, consolidation all kinds of law relevant to the futures market.

According to the fast-paced environment of information technology and improving customer services, the design activities of logistics systems improve customer centric services and delivery performance implementing e-logistics system. The fundamental design issues that arise in the delivery system planning are optimizing the system with minimum cost and maximum throughput and service level. This study is concerned with the integrated model development of delivery system with customer responsive service level for DCM, Demand Chain Management. We used a two-step approach for this study. First, we formulated the supply, center facility planning using stochastic set-covering problem and assigned the customers to the supply center using clustering algorithm. Second, we developed vehicle delivery planning for a supply center based on GIS, GIS-VRP. Also we developed a GUI-type computer program for proposed method for supply center problem using GIS and Geo-DataBase of Busan area. The computational results showed that the proposed method was very effective on a set of test problems.
