Objectives: This study seeks to evaluate the vulnerability assessment of the human health sector for $PM_{10}$, which is reflected in the regional characteristics and related disease mortality rates for $PM_{10}$ in Busan over the period of 2006-2010. Methods: According to the vulnerability concept suggested by the Intergovernmental Panel on Climate Change (IPCC), vulnerability to $PM_{10}$ is comprised of the categories of exposure, sensitivity, and adaptive capacity. The indexes of the exposure and sensitivity categories indicate positive effects, while the adaptive capacity index indicates a negative effect on vulnerability to $PM_{10}$. Variables of each category were standardized by the rescaling method, and each regional relative vulnerability was computed through the vulnerability index calculation formula. Results: The regions with a high exposure index are Jung-Gu (transportation region) and Saha-Gu (industrial region). Major factors determining the exposure index are the $PM_{10}$ concentration, days of $PM_{10}{\geq}50$, ${\mu}g/m^3$, and $PM_{10}$ emissions. The regions that show a high sensitivity index are urban and rural regions; these commonly have a high mortality rate for related disease and vulnerable populations. The regions that have a high adaptive capacity index are Jung-Gu, Gangseo-Gu, and Busanjin-Gu, all of which have a high level of economic/welfare/health care factors. The high-vulnerability synthesis of the exposure, sensitivity, and adaptive capacity indexes show that Dong-Gu and Seo-Gu have a risk for $PM_{10}$ potential effects and a low adaptive capacity. Conclusions: This study presents the vulnerability index to $PM_{10}$ through a relative comparison using quantitative evaluation to draw regional priorities. Therefore, it provides basic data to reflect environmental health influences in favor of an adaptive policy limiting damage to human health caused by vulnerability to $PM_{10}$.

A study was carried out to find out the relationship between arginine vasopressin (AVP) release and plasma osmolality in 15 young men (age: 21.4 yr). After an overnight fasting, wale. (20 ml/kg) was imbibed, and venous blood and urine samples were collected every 30 min for 90 min. then 5% saline was infused (0.06 ml/min/kg) for 120 min. AVP was extracted on Sep-Pak column and measured by radioimmunoassay. Under basal condition, plasma osmolality (pOsm), AVP (pAVP) and aldosterone (pAldo) levels were 286.5 mOsm/kg, 1.1 pg/ml, and 140 pg/ml, respectively. pAVP became undetectable during maximum water diuresis, and increased in response to hypertonic saline infusion. pAVP level began to increase when pOsm was above 280 mOsm/kg. Changes in urinary AVP excretion (uAVP) was parallel to pAVP levels. The fall in pAVP was followed by a decrease in uAVP, uOsm and an increase in free water clearance, while the later rise in pAVP was followed by an increase in uAVP, uOsm and a decrease in free water clearance. When pooling all data together, relationships between pAVP and pOsm, and uAVP and uOsm were best expressed by an exponential relationship (r=0.78, 0.86, respectively). pAldo level decreased to 71 pg/ml after water ingestion, and decreased further to 30 pg/ml 2 hr after 5% saline infusion. Even at the same pNa, pAldo level during dehydration state was significantly higher than during hydration state. Negative exponential relation (r=-0.59) was observed between pAldo and pNa. Response to change in body fluid volume was greater in aldosterone than in AVP release.

Objectives: This analysis seeks to evaluate the impact of environmental health factors (EHF; e.g. hospital beds per capita, employees of medical institutions) on extreme-heat vulnerability assessment in Busan Metropolitan City during 2006-2010. Methods: According to the vulnerability concept suggested by the Intergovernmental Panel on Climate Change (IPCC), extreme-heat vulnerability is comprised of the categories of Exposure, Sensitivity, and Adaptive Capacity (including EHF). The indexes of the Exposure and Sensitivity categories indicate positive effects, while the Adaptive capacity index indicates a negative effect on extreme-heat vulnerability. Variables of each category were standardized by the re-scaling method, and then each regional relative vulnerability was computed with the vulnerability index calculation formula. Results: The extreme-heat vulnerability index (EVI) excepting EHF was much higher in urban areas than in suburban areas within the metropolitan area. When EHF was considered, the difference in the EVI between the two areas was reduced due to the increase of the Adaptive capacity index in urban areas. The low EVI in suburban areas was induced by a dominant effect of natural environmental factors (e.g. green area) within the Adaptive capacity category. Conclusions: To reduce the vulnerability to extreme heat in urban areas, which were more frequently exposed to extreme heat than others areas, public health and natural environments need to be improved in sensitive areas.

A reduced NaCl intake for the general population of the world has been recommended to reduce the overall blood pressure level and hence to reduce the overall incidence of cardiovascular disease. A high NaCl diet convincingly contributes to elevated arterial pressure in humans and animal models of hypertension. Among individuals there is considerable variability of blood pressure responsiveness to NaCl intake. In normotensive as well as hypertensive subjects, blood pressure can be judged to be salt sensitivity (SS) when observed to vary directly and substantially with the net intake of NaCl. The prevalence of SS in normotensive adults in the U. S. ranges from 15% to 42% 1md in hypertensive adults from 28% to 74%. SS is a risk factor for hypertension and may be an important marker in the identification of children for hypertension prevention programs. High NaCl intakes produce expansion of the extracellular fluid volume and thus increase blood pressure. Nonchloride salts of sodium does not expand the extracellular fluid volume and does not alter blood pressure. Blood pressure response to NaCl may be modified by other components of the diet. Low dietary intakes of potassium or calcium augment NaCl-induced increases of blood pressure. Conversely, high dietary intakes, of potassium or calcium attenuate NaCl-induced hypertension. A greater intakes of potassium or calcium may prevent or delay the occurrence of hypertension. SS occurs when dietary potassium is even marginally deficient but is dose-dependently suppressed when dietary potassium is increased within its normal range. Orally administered KHCO₃, abundant in fruits and vegetales, but not KCl has a calcium-retaining effect which may contributed to its reversal of pressor effect of dietary NaCl. Since nutrients other than NaCl also affect blood pressure levels, a reduced NaCl intake should be only one component of a nutritional strategy to lower blood pressure.

최근 몇 년간 전세계 게임시장에서 중국 게임 시장의 시장 점유율이 크게 확대되고 있고, 미국, 일본, 한국 등 게임 수출대국은 이를 겨냥하여 중국적인 요소를 발굴하여 세심한 수출전략을 추진해왔다. 이러한 연구배경을 토대로 본 논문은 미국, 일본, 한국의 주요한 게임 캐릭터를 분석하여 중국의 전통문화 요소에 대한 경험적인 분석을 제공하는데 목적이 있다. 본 연구자는 미국, 일본, 한국의 RPG게임을 선정하여 캐릭터가 갖고 있는 중국적인 요소에 대한 내용분석을 실시하여 기존 게임회사들이 게임 개발에 있어 중국적인 요소들을 어떻게 사용하여 왔는가를 고찰하였다. 동시에 중국인 게임 유저에 대한 설문조사를 실시하여 중국인 유저들이 선호하는 중국적 요소를 분석하였다. 주된 분석 결과는 내용분석과 설문조사가 다소 상반되게 나타났다. 특히 미국, 일본, 한국의 RPG 게임회사들은 한족의복보다는 만주족의복을 사용하는 비율이 두드러지게 나타났으나, 중국인 유저들의 실질적인 중국 스타일의 식별도와 미관정도의 평점은 한족 의복이 훨씬 높게 나타났다. 뿐만 아니라 중국 문화를 보다 심도있게 사용하는 게임 캐릭터배경에 중국인 유저들은 더 많은 호감도를 보였다. 따라서 단순히 중국적인 요소를 가미하는 기존방식에서 탈피하여 게임 개발단계에서부터 보다 유저 친화적인 중국적 요소에 대한 응용과 선별적인 고려가 필요하다. As the market sheare of the Chinese game market across the world has been largely expanded over a decade, big game exporters of USA, Japan, Korea have developed Chinese factors and promoted export strategies, that target China. The Purpose of this study is to analyze the popular game characters of USA, Japan and Korea in order to provide empirical analysis of traditional Chinese elements applied in existing games. The RPG games in USA, Japan and Korea were selected for the contents analysis of the Chinese elements to show how the existing game companies used Chinese elements. The main findings of the research from survey data are rather inconsistent with the content analysis. In particular, all the RPG game companies of USA, Japan and Korea showed a remarkable ratio of using Manzu clothes more than Hanzu clothes. But, the preference of real game users on the Manzu style were lower than Hanzu style. Moreover, Chinese users showed more preference of the game character background that users more deepen Chinese culture. We suggest that applying Chinese elements need to be more selective based on real user’s demand.
