  • This study was conducted to identify the potential of Quercus mongolica (QUM), Pinus densiflora (PID) and Pinus rigida (PIR) as a raw material for pellet production. Larix kaempferi (LAK), which has mostly been used for pellet production in Korea, was also used as a control. All specimens contained very minimal amounts of sulfur and chlorine. Ash content of LAK was the lowest, followed by PID, PIR and QUM. For the size distribution, the mass fraction between 0.42 mm and 0.25 mm was the highest in PIR. Most fuel characteristics of the produced wood pellets improved with the use of 12% moisture content (MC) particles and the increase of the ratio of length to diameter of a hole in flat-die (L/D ratio). When the MC, bulk density and durability of QUM, PID, PIR and LAK pellets was compared with the standards of the KFRI and ISO, the use of wood particles of 12% MC and flat-die with an L/D ratio of 5.00 for PID particles are suitable for high-quality pellets in the aspects of all fuel characteristics. For PIR and QUM, further work is needed to seek the optimum conditions for the production of high-quality and durable pellets.

  • Recently, a wide range of products incorporating cutting-edge technology are being introduced in various sectors of design. Belkin's WeMo or Phillips' Hue are representative examples. In this context, the color-responsive lighting bookcase is a design product that would satisfy the needs of contemporary consumers who seek entertainment in their purchases. By installing lightings that change color according to the user's behavior, this design reconceptualizes the bookcase as a source of entertainment rather than a mundane object of household furnishing. The lighting apparatus can be detached and reattached, serving as stand-alone equipment. The lighting bookcase is modularized, comprising extensions equipped with MCU (Micro Controller Unit), RGB LED and color sensors. The bookcase as a whole is extendable towards four directions up to nine units with the lighting bookcase at the center. The extended, multiple lighting bookcases are wired to receive power from the main bookcase, and are equipped with RGB LEDs but not with MCUs or color sensors. Receiving power and color signals from the main lighting bookcase, the sub-bookcases feature changing shades of color. Also, it includes IoT(internet of Things). This study is a proposal of a design product, modularized to control the shades of the bookcase lighting using these sensors.

  • Purpose : This study aims to seek out the risk of low-temperature burns and fire. Method : Hot vests are connected by higher voltage than walking voltage. Results : Accordingly, the possibility of low-temperature burns and fire was proved high. It was also shown that hot vests with relatively lower resistance on heat rays reached a higher temperature as the same voltage was applied. Conclusion : There are some problems with hot vests because they do not have any safety devices like a thermostat or a timer to prevent temperature increasing rapidly. For the purpose of reducing the risk of low-temperature burns and fire, setting the standard of the minimum resistance temperature and regulating the use of heat rays with lower resistance are necessary.

  • This study is to seek methods for optimum management of foodservice system for elementary schools in Korea through surveying and analyzing the current status of the "common-management foodservice system" and certain important factors relating to its operations. For the survey of the current status of the "common-management foodservice system", questionnaires are prepared as against schools adopting "common-management system"("Common Schools") as well as schools adopting "conventional management system" ("Conventional Schools") in Kyungsangbookdo ("Kyungbook") area. The survey items are composed of general items, items concerning tasks of dietitians, items concerning purchasing activities and items concerning level of recognition and job-satisfaction of the dietitians. Total 46 dietitians from Common Schools and 65 dietitians from Conventional Schools in Kyungbook region responded the questionnaires. The results of this study are as follows: 1. Information Concerning Dietitians Average age of the dietitians: 26.6 yrs Ratio of two years or less of experiences as school dietitian: Dietitians from Common Schools: 59.1% Dietitians from Conventional Schools: 50.8% 2. Types of the Foodservice In both schools, rural type are prevalent; however, between urban types and islands types, the ratio of urban types are larger than the ratio of islands types in Conventional Schools, and the opposite is true in Common Schools. 3. Decision of Suppliers The ratio of dietitian's participaion in the decision making reaches only 38.3%, indicating the possibility of problems in quality control and hygienic aspects of the food supply. 4. Factor Analysis of the Foodservice Duties Food supply and general affairs administration work was carried out very well (4.2), while personnel management and operational improvement work (2.8), nutritional education work (2.3), and information related work were poorly carried out. No significant differences were found between the two types of the foodservice management systems. 5. Job Satisfaction scores of Dietitians Dietitians were more satisfied with the works (50.0), supervision (50.5) and co-workers (46.9) than pay (18.0) and promotion (22.3).

  • The Japan National Committee for the Union for International Cancer Control (UICC) and UICC-Asia Regional Office (ARO) organized an international session as part of the official program of the 72nd Annual Meeting of the Japanese Cancer Association to discuss the topic "What is cost-effectiveness in cancer treatment?" Healthcare economics are an international concern and a key issue for the UICC. The presenters and participants discussed the question of how limited medical resources can be best used to support life, which is a question that applies to both developing and industrialized countries, given that cancer treatment is putting medical systems under increasing strain. The emergence of advanced yet hugely expensive drugs has prompted discussion on methodologies for Health Technology Assessment (HTA) that seek to quantify cost and effect. The session benefited from the participation of various stakeholders, including representatives of industry, government and academia and three speakers from the Republic of Korea, an Asian country where discussion on HTA methodologies is already advanced. In addition, the session was joined by a representative of National Institute for Health and Care Excellence (NICE) of the United Kingdom, which has pioneered the concept of cost-effectiveness in a medical context. The aim of the session was to advance and deepen understanding of the issue of cost-effectiveness as viewed from medical care systems in different regions.

  • All human being can't exist by oneself. That is, all human being depend on intimate attachment for their survival. Physical and psychological powers and control functions are prerequisites for one's survival and these serve important functions in interpersonal relationships. There are two kinds of powers and controls. One is positive power which helps one survive effectively. Another one is negative power which disturbs one's effective survival. Introspection is one of the positive power and most important process in understanding oneself and others. Thus, the purpose of this study is to elucidate the physical and psychological meaning of the characteristics of water and based on this meaning, to suggest one way of introspection. The authors reviewed the precept of water which is described in Bible and oriental classical books such as 'the Analects of Confuicus(論語)', 'Tao Te Ching(道德經)', 'Mencius(맹자)', 'Chronicle(史記)', 'The Doctrine of the Mean(中庸)', 'University(大學)'. The author also reviewed 'The History of Three Countries(삼국사기, 삼국유사)', 'The Precept of Religion', and 'the modern poems' which includes the symbolic meaning of water. The results are summarized as follows:1) The flow of water itself is the expression of introspection. Because, water does not flow without filling a puddle. 2) Water is the symbol of 'Immortality'. 3) Water symbolizes 'Modesty and Trust'. 4) Water is the symbol of 'Freedom from Greed'. 5) Water symbolizes 'Goodness and Beauty'. 6) Water symbolizes 'Naturality and Love'. Immortality, Modesty and Trust, Freedom from Greed, Goodness and Beauty, and Naturality and Love are eternal, universal values which all human should seek and achieve. By the process of introspection through the symbolic meaning of water, we can achieve these positive aspects of human mind and spirit.
