Miscanthus is one of the promising energy crops for producing bioethanol or bioenergy in many countries. A field of about 180 ha for miscanthus plantation was started for demonstration near Geum River in 2011. Since the size of the field is much larger than those of traditional cultivation for one single crop in this country, questions were raised if there are any environmental impacts from the energy crop plantation, particularly on water quality. In this study, water quality of runoff water from three different plots was analyzed for assessing the impacts of energy crop production. The results showed that there were no substantial differences among the plots; control, the first, and the second year growth fields. The concentrations of COD, T-N, and T-P were lower than those in runoff water from agricultural crop fields. The second year field showed a slight higher values of COD and T-N concentrations due to the biodegradation of residue of miscanthus which was not cultivated for observation. Commercial planation of miscanthus in a large scale would not result in a water quality problem when avoiding application of fertilizer as practiced in agricultural crop fields.

There are three basic modes of operation of ships: liner, tramp and industrial operations. Industrial operations, where the owner of the cargo, i.e. the industrial carrier controls the ships, abound in the shipment of bulk commodities, such as oil, chemicals and ores. Industrial carriers strive to minimize the shipping cost of their cargoes. This paper is concerned with the operational optimization problem of a fleet owned by major international oil company. The major oil company is a holding corporation for a group of oil producing, transporting, refining, and marketing companies located in various countries throughout the world. The operational optimization problem of the fleet is divided into two-phases. The front end corresponds to the optimization of transporting crude oil, product mix, and the distribution of product oil to meet market demand. The back end tackles the operational optimization problem of the fleet to meet the transportation demand derived from the front end. A case study is carried out with the H major oil company problem composed by reflecting the practices of an international major oil company. The results are summarized and examined in the point of optimization for the total operation of the H major oil company and the operational optimization problem of the fleet. The paper concludes with the remark that the results of the study might be useful and applicable in practices of these related decision problems.

This study aims to provide a new perspective on Disney's animations, by examining how Disney systematized and transformed his own ways of cognitive systems of producing meaning through the costumes of his characters. For this purpose, 10 Disney animations of which the main characters were costume-wearing humans were selected and analyzed. First, the characters' costumes of the passive female heroines were much different from those of the active female heroines while the costumes of male heroes did not have any common characteristics. Second, the characters' costumes according to the settings of the animations had different aspects: the Western-Europe-based animations exhibited the appropriate costumes of the set times, but the non-Western-Europe-based animations exhibited the imaginative costumes of Disney rather than the appropriate costumes of the actual countries. Third, the costumes played the role of expressing the situations of the animations, and had their own repetitive conventions in each animation. Changes in the situations or the upward mobility of the status could be found easily through the costumes, but such distinctiveness became less visible in the later animations. Disney displayed his own distinctive formula of visual aesthetics through the characters' costumes. But it is recommended that we should have the critical views on the cultural messages of Disney's to prevent fixed ideas or cultural prejudices.

도서는 환해성, 협소성, 격리성, 기상조건에 대한 의존성 둥 지리적, 자연적 환경 면에서 육지보다 불리한 여건을 가지고 있다. 또한 이로 인한 교통불편, 취약한 산업기반을 비롯 교육, 의료, 문화시설, 정보통신시설 둥 경제적, 사회적, 기반이 낙후되어 있으며, 하루가 다르게 변모하는 육지와 그 격차가 더욱 심화되어 가고 있다. 이러한 발전격차는 도서지역 도서인구의 급격한 감소 및 구성인구의 고령화라는 결과를 낳고 있으므로 도서지역의 정보통신에 대하여 연구하고자 한다.

This study examined the state of awareness, consumption, and purchasing behavior of Kimchi among Chinese adults in Beijing and Shanghai. Two-hundred Chinese individuals in Beijing and Shanghai were included as study subjects. The subjects selected "good Kimchi for Chinese taste" as excellent Kimchi; however, only 13% of the subjects selected "Kimchi from Korea is excellent." The first sites of Kimchi consumption in China included "home" (59.0%) and "restaurants" (40.0%) in Beijing and "restaurants" (57.0%) and "home" (32.0%) in Shanghai. Chinese people primarily purchase 400g pouches of Kimchi more than once a month, and the average price of Kimchi is RMB 12.59 in Beijing and RMB 18.32 in Shanghai. These results suggest that the interest in Kimchi varieties and the countries producing it differ among Chinese consumers depending on the region. Therefore, a sensory evaluation of Kimchi is essential to determine the preferred flavor of Kimchi among Chinese individuals and to promote the consumption of traditional Korean Kimchi.

Vegetarians have claimed and actively promoted the advantages of plant-based alternative milks as the best option for human nutrition and health, compared to the natural dairy milk. However, numerous scientific evidences and reports have demonstrated that the natural milk possesses more beneficial nutrients and bioactive components than artificially manufactured plant-derived milks. The biochemical and nutritional advantages and functionalities of natural dairy milk cannot be replaced by man-made or crafted plant-based beverage products. On the other hand, the tremendous increase in production and consumption of the plant-based alternative milks in recent years has led a serious business downturn in traditional roles and stability of the dairy industry, especially in the major dairy producing Western countries. Although plant-based milk alternatives may have some benefits on nutrition and health of certain consumers, the plant-derived alternative milks may not overshadow the true values of natural milk. Milk is not a high fat and high cholesterol food as animal meat products. Unlike plant-based alternative milks, natural milk contains many bioactive as well as antiappetizing peptides, which can reduce body weight. It has proven that taking low-fat, cultured and lactase treated milk and dairy products with other diversified nutritionally balanced diets have been shown to be healthier dietary option than plant-based milk/foods alone.
