This study aims to examine the difference of body image and psychological well-being of men and women according to appearance management. The subjects of the study were 673 college students who lived in Seoul and metropolitan areas. Statistical analyses used in the study were factor analysis, Cronbach's a, cluster analysis, ANOVA, Duncan test and $\chi^2-test$. The results of this study were as follows; 1. The body image was categorized into the three factors of personal interest innce, anxiety about weight and physical attraction. Appearance management was categorized into the appearance management through clothing, strict diet therapy and daily appearance management. The psychological well-being was classified as seven factors which include the life goal, self-acceptance, positive personal relations, self-regulation, personal development, environment control and responsibility. 2. The appearance management was classified by 4 groups as below: Daily appearance management group, strict diet therapy group, appearance management through clothing group and no interest in appearance group. 3. There were significant differences among the four groups regarding body image, psychological well-being and life satisfaction. First, appearance management through clothing group had more interest in appearance than other groups. In the case of weight awareness, strict diet therapy group and the appearance management through clothing group intended to have more concerns over their weight. The strict diet therapy group seemed to have an overall lower level of psychological well-being than other groups. Lastly, the appearance management through clothing group had a higher level of life satisfaction.

U. S. NRC Regulation Guide 1.52 regulating ESF ACS in nuclear power plants has been revised to revision 3. To apply reduction of operability test time, allowance of alternative challenge agents for in-place leak test of HEPA filters, and upgrade of Methyl Iodide penetration acceptance criterion in activated carbon performance test suggested in Reg. Guide 1.52(Rev.3) on Yonggwang units 5 and 6 ESF ACSes, technical feasibility study was carried out with on-site experiments as well as experiments with a lab-scale model. It was confirmed that the moisture in the system returned to the level before the test in 1 or 4 days even though the moisture was removed during the operability test lasting more than 10 hours. Therefore, it is appropriate to perform monthly operability test in 15 minutes just long enough to check the operability of equipment. To change challenge material for in-place HEPA filter leak test, size of aerosol, production rate, and leak detection capability were compared for DOP and PAO. It was concluded that PAO can be substituted for DOP in nuclear power plants. The upgrade of Methyl Iodide penetration acceptance criterion from 0.175 % to 0.5 % in active carbon filter bed deeper than 4 inches was to conform to the change of activated carbon performance test method to ASTM D3803(1989). It was confirmed that Methyl Iodide penetration acceptance criterion of 0.5 % under $30^{\circ}C$, relative humidity 95 % condition was conservatively good enough for testing performance of active carbon insitu. The licence change of Yonggwang units 5 and 6 has been completed based on this study.

In this paper, the resource adequacy as well as the optimum fuel mix is obtained by the following procedures. First, the regulation body, the government agency, determine the reliability index as well as the optimum portfolio of the fuel mix during the planning horizon. Here, the resources with the characteristics of public goods such as demand-side management, renewable resources are assigned in advance. Also, the optimum portfolio is determined by reflecting the economics, environmental characteristics, public acceptance, regional supply and demand, etc. Second, the government announces the required amount of each fuel-type new resources during the planning horizon and the market participants bid to the government based on their own estimated fixed cost. Here, the government announces the winners of the each auction by plant type and the guaranteed fixed cost is determined by the marginal auction price by plant type. Third, the energy market is run and the surplus of each plant except their cost (guaranteed fixed cost and operating cost) is withdrew by the regulatory body. Here, to induce the generators to reduce their operating cost some incentives for each generator is given based on their performance. The performance is determined by the mechanism of the performance-based regulation (PBR). Here the free-riding performance should be subtracted to guarantee the transparent competition. Although the suggested mechanism looks like very regulated one, it provides two mechanism of the competition. That is, one is in the resource construction auction and the other is in the energy spot market. Also the advantages of the proposed method are it guarantee the proper resource adequacy as well as the desired fuel mix. However, this mechanism should be sustained during the transient period of the deregulation only. Therefore, generation resource planning procedure and market mechanisms are suggested to minimize possible stranded costs.

The volume of air passengers and cargo transportation has increased rapidly in recent years. This trend will be even more noticeable as the high-tech service industry expands and the globalization progresses. In an effort to reflect and to cope with this trend, many conventions concerning international air transportation have been concluded. The Republic of Korea has also acceded to the Montreal Convention of 1999 on September 20th, 2007 which became effective on December 29th 2007. However, Korea currently does not provide any private law on the liability of domestic air carrier, leaving the regulation wholly to the general conditions of carriage of private air lines. These general conditions of carriage, however, are not sufficient to regulate the liabilities of domestic air carriers, because they cannot be fully recognized as a legitimate source of law applicable in the court. This situation is inconvenient for both air carrier and their customers. Thus, the Ministry of Justice of Korea has decided to enact a law that will regulate domestic air transportation, namely, "Domestic Carriage by Air Act", as a part of the Korean Commercial Code. So was composed a special committee for legislation of the Domestic Carriage by Air Act. This writer has led the committee as a chairman. The committee has held in total 10 meetings so far and has completed a draft bill for the part VI of the Korean Commercial Code, "Air Carriage." The essentials of the draft are as follows: First, the establishment of Part VI in the Commercial Code. The Korean Commercial Code already includes a series of provisions on road transportation in part II and carriage by sea in part V. In addition to these rules regulating different types of transportation, the Domestic Carriage by Air Act will newly establish part VI to regulate air carriages. Eventually, the Commercial Code will provide an integrated legal system on the transportation industry. Second, the acceptance of the basic liability system which major international conventions, such as Montreal Convention of 1999 and Guadalajara Convention of 1961, have adopted. This is very important, because the law of air carriage is unified worldwide through various international conventions, making it necessary and significant for the new act to achieve conformity between rules of international air carriage and that of domestic air carriage. Third, the acceptance of Rome Convention system on damage caused by foreign aircraft to third parties on the surface. Fourth, the application of rules on domestic road carriage or carriage by sea mutatis mutandis with necessary modifications. This very point is the merit of inserting domestic air transportation law into the Commercial Code. By doing so, the number of articles can be reduced and the rules on air carriage can conform to that of road transportation and carriage by sea. The bill is expected to be passed by the parliament at the end of this year and is expected to be effective by end of July 2009.

In order to understand the machanism of action and regulation of ${\beta}$-adrenergic receptor in terms of molecular level, the purification of receptor protein has a fundamental importance. Moreover, species differences among avian, amphibian and mammalian ${\beta}$-adrenergic receptors make it more important to purify mammalian ${\beta}$-adrenergic receptor. Because ${\beta}$-adrenergic receptor is an integral membrane protein, it must be solubilized from the membrane for the purification. The purpose of the present study was to solubilize and characterize the mammalian $\beta$-adrenergic receptor from guinea pig lung in quantities by more efficient and practical method eventually to purify receptor. Guinea pig lung membrane preparation was solubilized by sequential treatment of buffers containing low and high concentration of digitonin which are 0.2 and 1.2% respectively. About 50% of the total receptor pool was released by this double extraction procedure. The $\beta$-adrenoceptors in the digitonin extract were identified using the ${\beta}$-adrenergic antagonist, (-)-[$^3H$]-dihydroalprenolol ([$^3H$]DHA). The solubilized receptor retained all of the essential characteristics of membrane-bound receptor, namely saturability; stereoselectivity; high affinity to ${\beta}$-adrenergic drugs. For the measurement of soluble receptor activity, Sephadex G-50 chromatography method has been widely used. Inspite of its accuracy and wide acceptance, this technique employed troublesome column work which required long time to assay the activity of receptor. We employed another methods to measure receptor activity. When using 0.5% polyethylenimine pretreated GF/B glass fiber filter, filtration technique could be used to measure soluble receptor activity. This technique enabled us to reduce the total amount of time to assay by a factor of 4 as well as to detect soluble receptor. In the present study, we could establish more efficient and practical solubilization method of mammalian $\beta$-adrenergic receptor. The rapidity and high yield of this solubilization scheme, together with the favorable recovery of the receptor activity, are significant steps toward the ultimate purification of the mammalian $\beta$-adrenergic receptor. The result of this study together with more convenient purification method could provide large amount of purified receptor with ease for various research purposes.

Nutrition label (NL) on the package of processed food provides consumers with a reliable and consistent source of information . It has been considered as a useful aid for food selection and a potent educational tool for nutrition in daily life. Since current nutrition labeling regulation in Korea does not define a format for presenting nutrition information a wide variety of NL format exists in the markers created by individual manufacturers. Development of standard NL format and its registration remain to be the work for the professionals and government officials. However the acceptance and evaluation of NL by the consumers is a very important and necessary process in the development of NL formats. In this study four different formats A, B, C, D were formulated based on currently circulating labels and new U.S.NL. Subjects used for evaluation of these formats were middle -aged highly educated housewives, who and the potential users of NL. Major parameters observed through the questionnare were their nutritional knowledge of RDA, ability of IC(Information Comparison) and CA (Comprehension and Application of informed nutrient contents), as well as their preference to the different formats. The results are summarized as follows. 1) Of the 178 subjects , 89.9% of the middleaged housewives were college graduates. Their nutrition knowledge of RDA were relatively satisfactory showing over 80% correlation on the basic concepts and unit while for numerical value less than 50% correct answer. 2) IC test scores were significantly different among the formats showing the highest values for format A and B which are presented as absolute value and % RDA, respectively. Format C presented as serving size(number of products) showed the lowest score. CA scores were also significantly different, though the increased load of information did not facilitate to increase the consumers comprehension. 3) RDA knowledge test scores and the scores of IA and CA were correlated in format A and D but not in format B and C suggesting % RDA presentation would be more acceptable to the less educated group. 4) For the preference in the aspects of easiness and time-saving format A was the best one then format D supporting the result of IC and CA test. The results of the present study indicate the most useful and preferred format is the simplest format presented as absolute value without RDA, . The secondly preferred format is the new NL format of the US with much information .

This study was conducted to inquire about the view on childrearing of university women for the purpose of building up the positive parent- child relationship and setting up preliminary parenting education program. The subjects were 137 university women who were freshmen to junior in one women's university in Seoul. Using the self-report questionnaire, data were collected from December in 1998 to March in 1999 and the contents which subjects wrote down were categorized by content analysis method. The results were as followed: 1. The age range of subjects were 20-22 years and main rearer was her mother(71.5%) 2. The view of subjects were revealed by 374 statements and then tied together 34 themes: 'exemplary parent model as a guider'(8.6%), 'determination for oneself' (8.0%), 'expression of love'(6.2%), 'humanity education'(4.8%), 'carrot and stick'(4.5%), 'respect of personality'(4.3%), 'sound living habit'(4.1%), 'conversation'(3.7%), 'regulation of greediness' (3.7%), 'supply of live experience'(3.7%), 'supply of broad and substantial vision'(3.5%), 'free choice'(3.5%), 'broad-mindedness'(3.5%), 'consideration'(3.0%), 'doing together'(3.0%), 'propriety education' (2.4%), 'pursuit of naturalness'(2.4%), 'looking for one's life'(2.4%), 'confidence'(2.1%), 'rearing by oneself'(2.1%), 'encouragement'(2.1%), 'cultivation of right sexual senses'(2.1%), 'desirable home environment'(1.9%), 'doing one's best'(1.9%), 'understanding'(1.6%), 'psychological intimacy'(1.6%), 'treat fair'(1.6%), 'pursuit of physical, psychological health' (1.6%), 'concerning'(1.3%), 'religious life'(1.3%), 'respect of individuality'(1.3%), 'cooperation' (1.1%), 'often-minded family'(0.8%), 'positive attitude'(0.8%). 34 themes were categorized by 12 categories once more: 'mature parenthood'(15.5%), 'acceptance' (11.5%), 'autonomy'(11.5%), 'pursuit of healthy life style'(9.4%), 'eagerness'(9.1%), 'making efforts'(8.8%), 'education'(8.8%), 'emotional bonding' (7.8%), 'respect'(7.2%), 'corporal punishment' (4.5%), 'supporting'(3.2%), 'composition of environment'(2.7%). In conclusion, we could expect that university women had a democratic view on childrearing with love and autonomy for a base. So we need to offer them nursing implementations such as preliminary parenting programs and parenting consulting in order to promote positive and interactional parent-child relationship by strengthening their desirable view on childrearing.

Objectives: The aim of this study was to find out the attitude of Korean women towards IVF surrogacy which is not yet regulated by the law. Methods: We evaluated with a questionnaire, in how far IVF surrogacy was accepted in different groups of Korean women. Total 300 questionnaires were sent out to women who visited our infertility clinic, and to the nurses and office workers of our hospital. Among them, 246 questionnaires were returned, and 211 of them (85.7%) were complete and analyzed. The responders were 58 unmarried women and 153 married women including 60 infertile patients. Results: Only 17 (8.1%) women believed that IVF surrogacy was an acceptable treatment for infertile women without uterus (eg. MRKH or hysterectomized patients), and 125 (59.2%) women chose the adoption. There were no significant differences in response amongst different age group, marital status, or in relation to income level or educational level, or infertility status. A significantly higher level of acceptance was noted only in religious groups, especially in Christians. Most of responders (66.5%) chose unrelated and unknown women as a desirable host, and 28.4% of responders chose the sister or sister-in-law. Conclusions: Overall the different groups were critical towards IVF Surrogacy in Korea, irrespective of the infertile patient group. Despite the established clinical ability to have her own genetic child in women without uterus, this survey reveals that only minority supports the IVF surrogacy. So we need the survey with large, randomized population and then make a regulation about the IVF surrogacy in law.

The creation and acceptance of new technologies has been speeding up dramatically in modern times. There are also significant uncertainties about the future shape of markets, governance and social values that will have an important impact on organizations and their capacity to meet their objectives. These rapid technological and social change and uncertainties make the upsurge of interest in technology foresight, giving rise to its emergence as a global concept and policy tool. A wide range of future methods are available for technology foresight. Selection of methods will depend upon several factors, most notably available and the time financial resources, and the objectives of the exercise. Although Delphi has been widely used for many years, scenario becomes very popular in recent years. The use of scenarios can take better account of the complexity and unpredictability of the economic, social and political environments. Scenarios tell the stories describing paths to different futures, which help organizations make better decisions today. In this study, the scenario method was employed to draw the images of the future of renewable energy. Renewable energy grows dramatically in recent years. However, there is still considerable uncertainty with regard to the potential of renewable energy due to environment regulation, energy costs, and political and economic developments in the main supplier countries for oil and natural gas. Scenario can help us to identify the risks and opportunities when we develop the renewable energy, and to prepare for them. The scenario method is expected to be more utilized in the national technology foresight.

Sustainable development is important because the ultimate objective is efficient development combining the economic, social, and environmental aspects of urban conservation. Despite Korea's rapid urbanization and economic development, the distribution of resources is inefficient, and land-use is not an exception. Land use distribution is difficult, as it requires considering a variety of purposes, whose solutions lie in a multipurpose optimization process. In this study, Yangpyeong-eup, Yangpyeong, Gyeonggi-do, is selected, as the site has ecological balance, is well-preserved, and has the potential to support population increases. Further, we have used the genetic algorithm method, as it helps to evolve solutions for complex spatial problems such as planning and distribution of land use. This study applies change to the way of mutation. With four goals and restrictions of area, spatial objectives, minimizing land use conversion, ecological conservation, maximizing economic profit, restricting area to a specific land use, and setting a fixed area, we developed an optimal planning map. No urban areas at the site needed preservation and the high urban area growth rate coincided with the optimization of purpose and maximization of economic profit. When the minimum point of the fitness score is the convergence point, we found optimization occurred approximately at 1500 generations. The results of this study can support planning at Yangpyeong-eup.ausative relationship between the perception of improving odor regulation and odor acceptance.
