  • Background and purpose : Stroke is a leading cause of death in Korea. Early measures to prevent stroke are extremely important since it has no cure. Korean might have different risk factors since their dietary habits and socio-economical status differ from most western countries. However, the risk factors for stroke in Korea have not yet been identified. Moreover, the lifestyle of healthy Korean adults has not been investigated. In this study we investigate the lifestyle of healthy adults living in Seoul and rural areas and compare the lifestyles of the two. Methods : One hundred seventy one subjects were studied. Among the subjects studied, 128 were from Seoul, the other 43 were from the country area. The age of the subjects was limited to over 40 years. Blood pressure, fast blood sugar, and cholesterol were measured. The subjects' height, weight, body mass index, total body fat, skinfolds thickness of triceps, subscapular and abdomen were measured to determine obesity. Using a structured interview, we assessed : sodium intake, physical activity and exercise, consumption of vegetables, fat, fish and fruits. The results of the two groups were compared. Results : There were no statistical differences in age and education between the two groups of subjects. The mean age of the subjects were 66 years old. The subjects residing in rural areas had a higher intake of sodium(p<0.05), lower physical activity(P<0.05), and higher BMI and body fat (p<0.05) as compared to the subjects in Seoul. Subjects with hypertension were between 24% and 33% and the prevalence of hypertension was the highest when compared to the prevalence of DM or hypercholesterolemia. However, the prevalence of hypertension, DM, hypercholesterolemia, were not significantly different in these areas. Conclusion : Our results show that subjects living in rural areas eat more salty food, exercise less, and tend to be obese. The finding of this study lead to speculation that Korean living in rural areas have less information about the effects of diet on health than city dwellers do. General health and nutrition education programs aimed at the prevention of stroke and other such conditions for rural area Koreans may close the risk factor gap between rural and urban dwellers.

  • Recently, China has brought many political, economical, and ideological changes in order to complete the "socialistic market economy." In terms of legal system, they make much effort to seek compatibility and stability of law and order. China recognizes that the breakdown of corruption, which is rampant in society, is an essential short-cut for national development. To realize anti-corruption reformation, it strengthens the supervision of relatives and close officials of high-ranking government officials. Recently, China has suffered from expanded trade disputes internationally and has also experienced severe management-labor conflicts domestically due to economic recession. From 2012 onward, civil lawsuit and other litigations have increased sharply. Also, they face severe conflicts in the land system. It is expected that many disputes arise due to speculation on rural housing. Meanwhile, Mongolia expands the size of trade with Korea in mutual cooperation since their diplomatic relation in 1990 by entering more than 20 treaties and agreements. As Mongolia has rich natural resources and Korea is equipped with advanced science and technology, the two countries have opportunities to develop mutually beneficial cooperative relations. Recently, the arbitration system has attracted attention instead of litigation as a means of dispute settlement in line with the expansion of trade between Korea and Mongolia. This study would be helpful to figure out desirable methods for dispute settlements in case of trade disputes among Korean companies that would advance into China and Mongolia.

  • This study examines the relationship between sentiment of speculators and price movements in the futures markets of WTI crude oil, copper, and wheat during the period 2003~2014 using Granger causality tests. The results indicate that speculative positions overall has no predictive power for returns in each futures market. Rather, returns seem to have effects on speculators' sentiment especially during periods of both economic expansion and recovery. During a recession, meanwhile, changes of speculators' sentiment index in the WTI crude oil and copper markets provide predictive power for returns in a positive direction, suggesting that speculators' pessimistic sentiment aggravates declines in commodity prices. Since the effects of speculative positions on market prices are ambiguous, tight regulations on speculative trading are not advisable. In a bearish market, however, regulatory bodies should consider raising speculative position limits because large speculative short positions and (or) liquidation of index traders' long positions may lead steep price declines.

  • This paper is written for analyzing the history of the Korean game legislation system. The regulation system of amusement place business that is discussed in this paper was started at the Enforcement Rule of the Amusement Place Act of 1973. It was maintained till 1999 and comes under the quickening period of the current game legislation. The legal regulation of this times was accomplished through the Amusement Place Act, the Amusement Place Business Act and the Public Health Act. The amusement place business was differentiated into the athletics facility business, the amusement facility business and the game proffer business of current legislations. The game proffer business succeeds to the kernel of the regulation system of amusement place business. Therefore, The basis of the current game legislation was constituted in the times of the regulation system of amusement place business. Two cores of the regulation system of amusement place business, (1) the separation of the amusement instrument and the speculation, (2) the regulation of a place of business, are still the important issues of the current game legislation.

  • In the 1970s, increasing penetration of the housing co-housing policy, reconstruction be a great success to improve 1990‘s Old aged apartment's performance. However, in case of reconstruction, it causes the problem such as city environment destruction, resource waste, real-estate speculation etc. With the trend of sustainable construction and resource recycling, remodeling gets more attention than before. In case of country's remodeling, conventional method causes some problems such as delayed construction period and increased cost. Therefore, efforts that obtain economical efficiency are required to power remodeling through use of prefabrication method like PC technology that is useful for reduction effect of construction period, cost and site labor and excellent quality. This research indicates reduceing factor for facilitating prefabrication method and technology selecting framework through specific of Expanding Floor method and remodeling cases to increase the efficiency of remodeling, considers construction parties approaching plan for prefabrication as occasion that powers remodeling.

  • Rooftop greenery has been used as a way to solve urban environmental problems by creating green space in densely populated cities. This study was carried out to suggest more effective designs for roof-garden at hospitals through a post-occupancy evaluation. The roofgarden of Asan Medical Center was evaluated with regards to setting, proximate environmental context, users, and design activity by a multi-method including plan investigations, observations, in-depth interviews and questionnaires. The results are summarized as follows; the users' main activities included resting, walking, and talking. A number of users were observed at shaded spaces sitting on such things as benches, pergolas, and shelters. The satisfaction of the users showed high satisfaction level except in the amount of shade, facilities, and shelter. The variables affecting a overall satisfaction were ‘accessibility’, ‘safety’, ‘quality of surroundings’, and ‘suitability for speculation’. By comparing the design concept with using pattern, designer's intention was not reflected sufficiently in several aspects such as ‘event deck for therapy programs’, ‘grove and path’, and ‘low planters’. This study suggests some design implications; it is necessary to furnish shaded sitting places for passive behaviors and pathways for walking or a light exercise. A wind-break wall with glass windows could widen the users' views in a limited space. Natural shade like tree shade or pergola are more desirable than artificial shades. As for the vertical location of the roofgarden, the middle floor could be better than top area for accessibility. Characteristics of building and users should be considered in detail to provide distinct spaces. Proper technical standards for the greening of artificial ground should be established.

  • Objectives: Even though experimental studies have suggested that iron can be involved in generating oxidative stress, epidemiologic studies on the association of markers of body iron stores with cardiovascular disease or cancer remain controversial. This study was performed to examine the association of serum ferritin and transferrin saturation (%TS) with all-cause, cancer, and cardiovascular mortality. Methods: The study subjects were men aged 50 years or older and postmenopausal women of the Third National Health and Nutrition Examination Survey 1988-1994. Participants were followed-up for mortality through December 31, 2006. Results: Serum ferritin was not associated with all-cause, cancer, or cardiovascular mortality for either men or postmenopausal women. However, all-cause, cancer, and cardiovascular mortality were inversely associated with %TS in men. Compared with men in the lowest quintile, adjusted hazard ratios for all-cause, cancer, and cardiovascular mortality were 0.85, 0.86, 0.76, and 0.74 ($p$ for trend < 0.01), 0.82, 0.73, 0.75, and 0.63 ($p$ for trend < 0.01), and 0.86, 0.81, 0.72, and 0.76 ($p$ for trend < 0.01), respectively. For postmenopausal women, inverse associations were also observed for all-cause and cardiovascular mortality, but cancer mortality showed the significantly lower mortality only in the 2nd quintile of %TS compared with that of the 1st quintile. Conclusions: Unlike speculation on the role of iron from experimental studies, %TS was inversely associated with allcause, cancer and cardiovascular mortality in men and postmenopausal women. On the other hand, serum ferritin was not associated with all-cause, cancer, or cardiovascular mortality.

  • Based on travel literatures written by the Joseon literati, the different picture of seventeenth- and eighteenth-century Buseok monastery from the one today emerges. Not only do the buildings removed from the monastery today reappear, but the quite different way of the monastic operation comes to light. This observation leads to a speculation that the monastery was functionally and spatially divided into two territories; that of the Immeasurable life hall and of the Dharma hall. The Immeasurable life hall's precinct was built at the site open to the west providing a grand vista of mountainous area. This siting, originally having a close relation with the visualization such as the Sixteen contemplation, not simply gave such a special attraction that the first built architectural composition has lasted through the centuries to the late Joseon, but also granted to the Chwiweon pavilion located at the western side of the precinct a special meditative quality. As the monastery has suffered from a number of heavy duties in the Joseon period, the architectural attraction of the precinct was mobilized to promote the monastic identity as the legitimate monastery first built by Uisang, the founder of Hwaeom Buddhsim. Especially, the Chwiweon pavilion offered a mental space so that the literati might form an affirmative attitude toward the monastery and the monks. The Dharma hall's precinct was built based on the direct replication of the architectural layout presented in liturgy books for the Water and Land rite as well as the Vulture Peak rite. This layout is generally called the Court-type enclosed by four buildings, which has been widely fashioned in the late Joseon period. This characteristic gave to the Dharma hall precinct an arbitrary and anonymous quality, which helped not only avoid the tourism of the literati, but also secure the sacrality and ritual efficacy at occasions of Buddhist rites. This division of territories of the monastery can be understood as the strategic reaction from the monks in order to survive in the age of oppression against Buddhism. In result, the identity of Buseok monastery in the late Joseon was established as the Nine-rank sanctuary where Bodhisattvas permanently resided.

  • Recent evidence has suggested that trunk neural crest cell generally assumed to have equivalent differentiation potentials, demonstrate differentiation bias along the anterior/posterior axis. In amphibian and fish, neural crest cells give rise to three chromatophore types, melanophores, xantho-phores, and iridophores. Each pigment cell type has distinct characteristics but there is speculation about the cellular plasticity that exists among them. Neural crest cells migrate along specific routes, ventromedially and dorsolaterally. Neural crest cells that travel dorsolaterally are the first cells to begin migration in the axolotl and are the major contributors to the visible pigment pattern. Many factors and mechanisms that are responsible for guiding migratory neural crest cells along potential pathways or determining their fate remain unknown. A single lineage of the crest, which becomes restricted to one of the three pigment cell types, gives us the opportunity to examine the existence of neural crest stem cell populations and cellular plasticity. Study presented here showed results from recent in vitro studies designed to identify parameters influencing differentiation events of individual neural crest-derived pigment cell lineages. Melanophore production from neural crest explants originating from different levels along the anterior/posterior axis of wild type-axolotl embryos were compared and demonstrate that the differentiation of melanophores is enhanced in subpopulation of neural crest treated with forskolin. Forskolin (an adenylate cyclase activator) increases intracellular CAMP concentration and eventually activates the protein kinase-A signaling pathway. Melanophore number, melanin content, and tyrosinase activity in explants taken from the anterior-most region of the crest increased significantly in response to forskolin treatment. This study suggests implications of region specific influences and developmental regulation in the development of pigment pattern.

  • Objective : To report the prevalence of lupus anticoagulants and anticardiolipin antibodies in patients with recurrent spontaneous abortion and infertility. Material and Method: Lupus anticoagulants and anticardiolipin antibodies were analyzed by Diluted Russell's Viper Venom Test (DRVVT) and solid phase enzyme immunoassay, respectively. Results : In 200 patients with infertility, there were 6 cases (3%) with positive lupus anticoagulants or anticardiolipin antibodies. Of these, 3 patients (1.5%) showed positive lupus anticoagulants and anticardiolipin antibodies, respectively. In 120 patients with recurrent spontaneous abortion, there were 13 cases (10.8%) of positive lupus anticoagulants or anticardiolipin antibodies. Of these, one patient (1%) showed lupus anticoagulants and 12 patients (10%) showed anticardiolipin antibodies. But in two groups, there was no cases with positive lupus anticoagulants and anticardiolipin antibodies. Conclusion: Lupus anticoagulants and anticardiolipin antibodies are definite cause of recurrent spontaneous abortion. There has been a speculation that they might be associated with infertility and repeated IVF failures. But it was found that the role of lupus anticoagulants and anticardiolipin antibodies in these cases are not clear.
