One of the noticeable trends of female wear in 1990s is the Outwearization of Underwear as it is called 'Lingerie look' This trend meaned 'Exposure Fashion' raised splendidly its head to the whole stage of fashion destrying the tradional concept having divided the fashion between outwear and underwear by Madonna an Americal populer singer showed up in front of the audience wearing the corset-dress as a stage custome. This corset-dress which can not be recognised whether it is underwear or outwear has been diffused into the mass as a fashionable trend re-gardless of any reason; therefore discrimi-nation of wear by space by far that is underwear should have the sstandard telling between private and public sector has been gradually tumbled. By the way what has propelled desigers to introduce the style continuously having the underwear motive such as outwear almost as same as underwear or underwear worn on out-wear etc. and has made it a fashion trends? How do we accept this "Ligerie look'fashion" The rearch on vogue of outwearization of underwear started by the questions above can be summarized as the followings The division between the sprit and the ma-terial-economic shrinkage by the collapse of the bubble economy in the late of 20 century and expectation for the next century doubt by changes of international politics dynamics for the next century and increasement of psycho-logical tention by the environmental destruc-tion etc, has been extended to break the sense of value down These frustration of the tra-ditional values and dissatisfaction on the pres-ent have reflected on the fashion pursuing some more sensational style to increase the ex-posure of the body. The revolution of wearing bouncing the con-servatismhas outwardly expressed underwear of the private sector. Therefore the spatial concept of wear which for the public sec-tor has been fallen into pieces and has broken the wall of the concept fixed by outwear on underwear. in addition the stage costome for the popular people like Madonna has not been limited by the specularity any more and has been assimilated with the normal wear on the street to take the distinction for away. The circumstances of the late of 20 century pursuing sensation and making sex commer-cialized have accordance with the outweari-zation of underwear. there it is on the basis of Minimalist's dogmatism has been expressed the maximization of expoure in the pubric space to popularize bra pants(knickers) as outwear. The reaction on the attribute of hiding and shanding has brought 'See-Through fashion' with the transparent materials, The contemporary doubt recalling the mem-ory of the past has sublimated corset which was an instument of toture for women into Romanticism to introduce it to fashion with the development of a new material not to be a tool of any oppression and maltretment any longer. The popularization of outwear like underwear what's more has brought high quality of underwear. There it has called for the variety of materials such as knit demin and velvet etc, and has urged the famous designers to enlarge their working boundaries to underwear designs, Besides outwearization of underwear has been popular even in the Orient which has the con-servative opinions on exposure ; so changes of the thoughts can be seen among the establish-ment generation on exposure of the body. As the more high tech information publi-cized and the more technology and media digitalized the more expression being analog the pursue for the new in fashion with vision never been seen and even though it is imprac-tical the experimental designers have drived the freedom beyond the traditional roles of the previous century. Consequently outwearization of underwear may be viewd as a trial as an expression responded the contemporary background. This trend in my opinion will have been lasted for a while by being proliperlated among lasted for a while by being proliperlated among the pub-lic who has the century-end anxiety and doubt and expectation for the next century.

The purpose of this study was to provide basic data necessary for creating a more successful health enhancement program, health education and health policy which can enhance health management abilities and enable a healthy school life by examining relations between high school students' health perception, who are in early adolescence, and their health promotion behavior. The subjects in this study were 813 students from 8 high schools on Jeju Island. The collected data were analyzed with t-test and one-way ANOVA through questionnaires by researcher on the basis of advance research. The findings of this study were as belows : 1. When general characteristics were considered, health perception was more significantly affected by those who were boys, whose family income was on a higher level, who scored better in school, whose parents were more concerned about their children's health, and who had experiences of being hospitalized. Especially, the more parents were concerned about their children's health, the higher the child's self-confidence on health(p<.05), anxiety on health(p<.05), practicality on disease prevention(p<.05), self-confidence on future health(p<.01), health care ability(p<.01), and family roles on health(p<.05). The less parents were concerned about their children's health, the higher the child's anxiety on disease(p<.01) and uncertainty on future health(p<.01). 2. When students' health promotion behavior was concerned, in the area of Eating Habits, having regular meals(72.9%), moderate consumption of meat(89.7%) and a balanced diet(64%) were common, whereas having a regular breakfast(37.4%) and eating vegetables and fruits(43.6%) were rare. In the area of Exercise, all subareas such as exercising 3 or 4 times a week(76.7%), more than one hour of exercise at a time(74.9%), a short distance walk(51.8%), exercise within one hour after meals(87%), and whether wanning up or not(88.6%) were above average. In the area of Personal Hygiene, all subareas such as drinking boiled water(57.3%), washing hands after using the bathroom(71%), brushing teeth after eating(42.4%), washing up after going out(50.3%), and washing hair and taking a frequent bath(77.2%) were rare. In the area of Control of Personal Relations, consulting personal problems with family(78.7%) had a positive response, whereas meeting someone new(59.8%), maintaining sound relations with the opposite sex(47.3%), having respect for one's opinion(51.5%), and maintaining peaceful relations with people(58.4%) had rare negative results. In the area of Stress Management, not being competitive(69.4%), releasing problems(62.4%) and sleeping soundly(66.2%) were common, whereas having your own ways to relieve stress(46.8%) and having your own dreams and hopes(58.5%) were rare. 3. When general characteristics were considered, as far as relations of health promotion behavior were concerned, the boys were significantly different in the area of Eating Habits(p<0.01) and Exercise(p<0.01), and the girls were in the area of Personal Hygiene. As family economic status was high and parents were concerned about their children's health, the entire areas of health promotion behavior were significantly different. Whether or not they were hospitalized made no significant difference in statistics. 4. When their regions were considered, it comparing city to town, there was no statistically significant difference in health perception and relations of health promotion behavior according to general characteristics. As seen in the results above, high school students' level of health perception and level of practicing health promotion behavior were generally low. In conclusion, by enhancing health perception, a plan for activating health education, which can implement positive health promotion behavior, should be made.

Purpose : To raise awareness of the clinical importance of, and the need for proper management of acute focal bacterial nephritis(AFBN), we analyzed 22 AFBN patients and 22 other upper urinary tract infection patients by use of comparative studies. Methods : From January 2000 to May 2002, 22 AFBN patients aged from 1 month to 12 months were selected. As a control group, 22 UTI patients with no radiologic abnormalities were selected and matched by age and sex. Results : The incidence of AFBN was more common in boys than in girls. Since both groups had similar symptoms, it was difficult to diagnose AFBN by clinical presentations alone. ESR and CRP were significantly higher in AFBN patients. The most common causative organism was E. coli in both groups. On the sonographic findings, the most lesions were seen on the upper lobe of the kidney; more frequently, on left kidney. The lesions showed globular or wedge-shaped increased echogenecity. $^{99m}Tc-DMSA$ scan showed the complete coincidence of the location, size and shape in all cases compared to the findings of renal sonography. Conclusion : The roles of renal sonography and DMSA scan were very important, and ultrasonography was an excellent initial tool in diagnosing AFBN. Since the degree of infection in AFBN is more severe than other urinary tract infections and evollution into a renal abscess is possible, early diagnosis and appropriate antibiotics therapy is essential.

Background: Thyrotoxic periodic paralysis is an uncommon illness characterized by intermittent flaccid paralysis of skeletal muscle, usually accompanied by hypokalemia, in patient with hyperthyroidism. However, the pathophysiology of thyrotoxic periodic paralysis remains largely unexplained and controversial. This report describes the clinical and biochemical findings in 19 patients with thyrotoxic periodic paralysis who were examined at the Yeungnam University Medical Center(YUMC) during the past decade. Methods: The medical records of 997 YUMC patients, seen between 1986 and 1996, with diagnosis of hyperthyroidism were reviewed. Nineteen patients out of 997 hyperthyroidism patients were diagnosed, and examined by history, physical examination, serum electrolyte value, and thyroid function test during paralysis. On the basis of these results, comparisons were made on age, sex, precipitating factors, timing, affected limbs, prognosis, serum potassium and serum phosphate and thyroid hormone levels. Results: The prevalence of periodic paralysis in hyperthyroidism was 1.9 percent and the male to female prevalence ratio was 30:1 and in all patients, the development of perodic paralysis was correlated with hyperfunctional state of the thyroid gland. Eleven cases of periodic paralysis were associated with hypokalemia and their thyroid hormone levels were significantly more increased than those of the patients without hypokalemia. Interestingly, our study shows the recurrence of paralysis after treatment. Conclusion: Although the precise pathophysiology of the disease is as yet undefined and controversial, it occurs primarily in Asians with an overwhelming male preponderance and prevalence of 2 percent in hyperthyroidism. The interactive roles of thyroid hormone, Na-K pump, and genetically inherited defect in the cellular membrane potential of the skeletal muscle can be speculated. Further investigation will be needed to firmly establish the mechanism of thyrotoxic periodic paralysis.

Non-alcoholic fatty liver disease accompanies the rise in the prevalence of obesity, diabetes and the tendency toward high-fat dietary habits. Specifically, the higher prevalence of non-alcoholic fatty liver disease in men and postmenopausal women seems to be caused by the protective effects of estrogen against liver fibrosis, or lack thereof. There are no effective preventive therapies for liver diseases because the mechanisms underlying the progression of fatty liver diseases to chronic liver diseases and the protective effects of estrogen against fibrogenesis remain unclear. Recently, it has been reported that the hedgehog signaling pathway plays an important role in the progression of chronic liver diseases. Hedgehog, a morphogen regulating embryonic liver development, is expressed in injured livers but not in adult healthy livers. The level of hedgehog expression parallels the stages of liver diseases. Hedgehog induces myofibroblast activation and hepatic progenitor cell proliferation and leads to excessive liver fibrosis, whereas estrogen inhibits the activation of hepatic stellate cells to myofibroblasts and prevents liver fibrosis. Although the mechanism underlying the opposing actions of hedgehog and estrogen on liver fibrosis remain unclear, the suppressive effects of estrogen on the expression of osteopontin, a profibrogenic extracellular matrix protein and cytokine, and the inductive effects of hedgehog on osteopontin transcription suggest that estrogen and hedgehog are associated with liver fibrosis regulation. Therefore, further research on the estrogen-mediated regulatory mechanisms underlying the hedgehog-signaling pathway can identify the mechanism underlying liver fibrogenesis and contribute to developing therapies for preventing the progression of fibrosis to chronic liver diseases.

The degree of females' participation in corporate activity has been recently increased over the world and females' participation in economic activity may be new dynamic fuel for the Korean economy that falls into the vicious cycle of low growth. Start-up, therefore, has increasingly taken attention as an opportunity for females whose careers were interrupted to re-enter the labor market. The need for studies that examine factors influencing the decision of start-up is also increased along with the increase of the ratio of females' start-up. This study aims to verify effects of the women's characteristics(women discrimination, women's role conflict) and the human networks of females whose careers were interrupted, with the intention for entrepreneurial intention, which are mediated by personal attitudes and subjective norm suggested by Ajzen's Theory of Reasoned Action, based on an empirical research. The findings show that the human networks of females have an effect on attitudes toward start-up activity and subjective norm and the woman discrimination influence the personal attitudes. In contrast, the women's role conflict have no effect on both personal attitude toward start-up activity and subjective norm. This can be supposed as an outcome resulted from the subjects' low level of conflict caused by their sex roles, on their age distribution. The relation between subjective norm and entrepreneurial Intention seemed to be moderated by their perceived strong entrepreneurial supporting policy. Their attitudes toward start-up activity were found to have a mediating effect on the relation between the women discrimination, human networks and entrepreneurial Intention, while the subjective norm only mediated the relation between human networks and entrepreneurial Intention. Based on such results, this study attempts to suggest theoretical suggestions and the direction of various entrepreneurial supporting policy for the increase and the growth of start-up of females whose careers were interrupted, in Korea.

To clarify annual reproductive cycle of Koran dark sleeper, odontobutis platycephala, we examined the seasonal changes of gonadosomatic index(GSI), testicular development stages and sex steroid hormones in blood from December 1995 to November 1997. Testis was podlike shape from July to October, and tadpole-like shape from November because of its expanded posterior part. GSI was 0.14~0.18 from July to September and increased to $0.43{\pm}0.04$ in October and then was not changed significantly until February. GSI was reincreased to $0.52{\pm}0.09$ from March and then was kept at similer levels until May, but fell down to $0.28{\pm}0.05$ in June. As results of histological observation, testis was divided into 3 parts(anterior, boundary, posterior) in the development progress of germ cells. In July, the testis was composed of only spermatogonia without seminiferous tubules in most fishes. In the anterior part of testis, the ferquency of spermatogenesis stage seminiferous tubules appearing in August was more than 80% from September to December. decreased gradually from January to March and drastically in April, and then disappeared in June. The frequency of spermiogenesis stage seminiferous tubules appearing in December, increased gradually from January to March and drastically to 80% in April, and reached to 90% the highest levels of the year in June. Post-spawning stage seminiferous tubules did not appear throughout the year. The frequency of spermatogonia was 100% and 65% in July and August, and less than 20% in the rest period of the year. In the boundary part, the frequency of spermatogenesis stage seminiferous tubules appearing in August increased from September and reached to 82% in November, decreased from December, adn disappeared in March. The frequency of spermiogenesis stage seminiferous tubules appearing in November was less than 18% until February, and increased to 29%~57% from March to June. The frequency of post-spawning stage seminiferous tubules appeared 12%~25% only from March to June. The frequency of spermatogonia was 100% in July, decreased to 85% in August and 10% in November, and increased gradually from December to 50% in April, and decreased again from May to June. In the posterior part, seminiferous tubules with some seminiferous tubules increased drastically 80%~85% in August and September, decreased drastically from October to November and remained below 10% until February, and disappeared after March. The frequency of spermiogenesis stage seminiferous tubules appearing in August increased sharply from October and reached to 75% in November. decreased to 15% in December and no significant changes until March, and disappeared after April. The frequency of post-spawning stage seminiferous tubules appearing very early in November increased to 82% in December and 85%~95% until June. The frequency of spermatogonia was 100% in July, decreased drastically to 15% in August, disappeared from October to Mrch, but reappeared from April and kept at less than 10% until June. The blood level of testosterone (T) increrased gradually from August was $0.61{\pm}0.09 ng/m\ell$ in November, increrased drastically to $3.99{\pm}1.22 ng/m\ell$ in December and maintained at in similar level until March, and decreased to $0.25{\pm}0.14 ng/m{\ell} ~ 0.17{\pm}0.13ng/m{\ell}$ in April and May and no significant changes until July (P<0.05). The blood level of 17, 20 -dihydroxy-4-pregnen-3-one $ng/m{\ell}$in the rest of year without significant changes(P<0.05). Taken together these results, the germ cell development of testis progressed in the order of posterior, boundary, anterior part during annual reproductive cycle in Korean dark sleeper. The testicular cycle of Korean dark sleeper was as follows. The anterior part of testis : i.e. spermatogonial proliferation period (July), early maturation period (from August to November), mid maturation period (from December to March), late maturation period (from April to May) and functional maturation period (June) were elucidated. The boundary of testis, i.e. spermatogonial proliferation period (July), early maturation period (from August to October), mid maturation period (from November to February) and the coexistence period of late maturation, functional maturation and post-spawn (from March to June) were elucidated. The posterior of testis, i.e. spermatogonial proliferation period (July), mid maturation period (from August ot September), late maturation period (October), functional maturation period (November) and post-spawn period (from December to June) were elucidated. It was showed that the changes of sex steroid hormone in blood played a important roles in the annual reproductive cycle of Korean dark sleeper.

Over the past decade, there has been a rapid diffusion of technological devices and a rising number of various devices, resulting in an escalation of virtual reality technology. Technological market has rapidly been changed from smartphone to wearable devices based on virtual reality. Virtual reality can make users feel real situation through sensing interaction, voice, motion capture and so on. Facebook.com, Google, Samsung, LG, Sony and so on have investigated developing platform of virtual reality. the pricing of virtual reality devices also had decreased into 30% from their launched period. Thus market infrastructure in virtual reality have rapidly been developed to crease marketplace. However, most consumers recognize that virtual reality is not ease to purchase or use. That could not lead consumers to positive attitude for devices and purchase the related devices in the early market. Through previous studies related to virtual reality, there are few studies focusing on why the devices for virtual reality stayed in early stage in adoption & diffusion context in the market. Almost previous studies considered the reasons of hard adoption for innovative products in the viewpoints of Typology of Innovation Resistance, MIR(Management of Innovation Resistant), UTAUT & UTAUT2. However, product-based antecedents also important to increase user intention to purchase and use products in the technological market. In this study, we focus on user acceptance and resistance for increasing purchase and usage promotions of wearable devices related to virtual reality based on headgear products like Galaxy Gear. Especially, we added a variables like attitude confidence as a dimension for user resistance. The research questions of this study are follows. First, how attitude confidence and innovativeness resistance affect user intention to use? Second, What factors related to content and brand contexts can affect user intention to use? This research collected data from the participants who have experiences using virtual rality headgears aged between 20s to 50s located in South Korea. In order to collect data, this study used a pilot test and through making face-to-face interviews on three specialists, face validity and content validity were evaluated for the questionnaire validity. Cleansing the data, we dropped some outliers and data of irrelevant papers. Totally, 156 responses were used for testing the suggested hypotheses. Through collecting data, demographics and the relationships among variables were analyzed through conducting structural equation modeling by PLS. The data showed that the sex of respondents who have experience using social commerce sites (male=86(55.1%), female=70(44.9%). The ages of respondents are mostly from 20s (74.4%) to 30s (16.7%). 126 respondents (80.8%) have used virtual reality devices. The results of our model estimation are as follows. With the exception of Hypothesis 1 and 7, which deals with the two relationships between brand awareness to attitude confidence, and quality of content to perceived enjoyment, all of our hypotheses were supported. In compliance with our hypotheses, perceived ease of use (H2) and use innovativeness (H3) were supported with its positively influence for the attitude confidence. This finding indicates that the more ease of use and innovativeness for devices increased, the more users' attitude confidence increased. Perceived price (H4), enjoyment (H5), Quantity of contents (H6) significantly increase user resistance. However, perceived price positively affect user innovativeness resistance meanwhile perceived enjoyment and quantity of contents negatively affect user innovativeness resistance. In addition, aesthetic exterior (H6) was also positively associated with perceived price (p<0.01). Also projection quality (H8) can increase perceived enjoyment (p<0.05). Finally, attitude confidence (H10) increased user intention to use virtual reality devices. however user resistance (H11) negatively affect user intention to use virtual reality devices. The findings of this study show that attitude confidence and user innovativeness resistance differently influence customer intention for using virtual reality devices. There are two distinct characteristic of attitude confidence: perceived ease of use and user innovativeness. This study identified the antecedents of different roles of perceived price (aesthetic exterior) and perceived enjoyment (quality of contents & projection quality). The findings indicated that brand awareness and quality of contents for virtual reality is not formed within virtual reality market yet. Therefore, firms should developed brand awareness for their product in the virtual market to increase market share.
