  • Spent resin waste containing a high concentration of $^{14}C$ radionuclide cannot be disposed of directly. A fundamental study on selective $^{14}C$ stripping, especially from the IRN-150 mixed bed resin, was carried out. In single ion-exchange equilibrium isotherm experiments, the ion adsorption capacity of the fresh resin for non-radioactive $HCO_3{^-}$ ion, as the chemical form of $^{14}C$, was evaluated as 11mg-C/g-resin. Adsorption affinity of anions to the resin was derived in order of $NO_3{^-}$ > $HCO_3{^-}{\geq}H_2PO_4{^-}$. Thus the competitive adsorption affinity of $NO_3{^-}$ ion in binary systems appeared far higher than that of $HCO_3{^-}$ or $H_2PO_4{^-}$, and the selective desorption of $HCO_3{^-}$ from the resin was very effective. On one hand, the affinity of $Co^{2+}$ and $Cs^+$ for the resin remained relatively higher than that of other cations in the same stripping solution. Desorption of $Cs^+$ was minimized when the summation of the metal ions in the spent resin and the other cations in solution was near saturation and the pH value was maintained above 4.5. Among the various solutions tested, from the view-point of the simple second waste process, $NH_4H_2PO_4$ solution was preferable for the stripping of $^{14}C$ from the spent resin.

  • Ship builder's requirement for a higher power output rating has lead to the development of super large two stroke low speed diesel engines. Usually a large-sized bore ranging from 8-14 cylinders, this engine group is capable of delivering power output of more than 100,000 bhp at maximum continuous rating. Other positive aspects of this engine type include higher thermal efficiency, reliability, durability and mobility. This all playa vital role in meeting the propulsion requirement of vessels, specifically for large container ships, of which speed is a primary concern to become more competitive. Consequently, this also resulted in the modification of engine parameters and new component designs to meet the consequential higher mean effective pressure and higher maximum combustion pressure. Even though the fundamental excitation mechanism unchanged, torsional vibration stresses in the propulsion shafting are subsequently perceived to be higher. As such, one important viewpoint in the initial engine design is the resulting vibration characteristic expected to prevail on the propulsion shafting system(PSS). This paper investigated the torsional vibration characteristics of these super large engines. For the two node torsional vibration with a nodal point on the crankshaft, a tuning damper is necessary to reduce the torsional stresses on the crankshaft. Hence, the tuning torsional vibration damper design and compatibility to the shafting system was similarly reviewed and analyzed.

  • In this paper, the concept and characteristics of the nuclear propulsion system were introduced and the state of the art for the nuclear-powered space propulsion in abroad were summarized. Since uranium used in nuclear propulsion has a very high energy density per unit mass, it has exceptional specific impulse performance compared to the existing chemical propulsion method and can reduce the amount of fuel loaded, thereby having advantage for long-distance exploration. For this reason, advanced countries in space development are recently spurring to the research of nuclear propulsion technology, and it is judged that the development of a propulsion engine using nuclear power is absolutely necessary in order to gain an competitive edge on the space development.

  • Adolescent health is considered to contribute to health promotion in the home and community in the near future as well as individual health. However, adolescent health has been neglected from education field because of competitive school education focused on the university entrance examination That's why I suggest in this study that we should pay much more attention to adolescent health condition and try to make It better, in terms of man-power development and life-health promotion for nation development The purposes of this study are as follows First, to look into a variety of adolescent health problems Second, to find out the situation and problems of current adolescent health promotion and school health education Third, to make an effort to find, based on the current situation, various developments of adolescent health promotion and school health education in terms of practical, political and environmental change There are used study methods as adolescent-related, school heath-related literature review and anlysis of statistical data The results and suggestions are as follows Teenagers have a great variey of health problems including most Important physical, mental and social developments Recently, chronic diseases, emotional problems, health-risk behaviors linked With adolescents are on increase The complicated disorders of physical, mental, social health rather than paricular aspects of health or health-behavior problems influence adolescent health problems adolescence is regarded as the period when most health-related behaviors are formed. Therefore, adolescent health promotion would he assured by developing the ability of controlling multi-dimensional health determinants in the early stage. Health promotion is a positive concept that each individual, family and community makes real efforts to improve their health To achive this, we need health educational, organizational, political and environmental supports. Adolescent health promotion in Korea has been systematically treated in the category of school health Current school health services have had lots of systemic, constitutional, administrative and educational flaws Accordingly, I'm concerned that we can afford to accept a variety of adolescent health needs However, I would say that if were not to make those flaws better, it's certain that Korean national competitive power and the quality of the lives of most Koreans Will he threatened someday We have to develop Comprehensive School Health Crriculum(CSHC) and set up its standards to Improve adolescent health. CSHC is an organizational and costant process. CSHC means an Important part of overall curriculums. In addition, I could say that it's an Important school health education acivity including current school health services-health care service and school health environment. In conclusion, in order to develop CSHC, we require school nurse's role changes, establishment and management of intergrated subject of health education, striking revision of school health law(or legislation of school health promotion law), reorganization of administration system, big changes in curriculum for school health educators.
