  • Seasonal and interannual variations of the oceanic condition in the surface layer of the northwestern East Sea are described. The seasonal variation shows two types in the water circulation. In the first type the East Korean Warm Current (EUC) Water are dominant in the East Korean Bay in spring, while in summer the cold water region develops as the North Korean Cold Current (NKCC) becomes strong. In the second type the cold water appears in the East Korean Bay from spring, but in summer the EKWC comes close to the coast, thus influencing the coastal cold water region. The characteristics of the interannual variation can be classified into 4 types according to the relative strength between the EKWC and the NKCC, and the paths of these currents. In each case various sizes of cyclonic cold eddies and/or anti-cyclonic warm eddies are formed frequently in the East Korean Bay.

  • A simple quasi-geostrophic model is considered to explain the separation of the East Korean Warm Current(EKWC) and formation of the North Korean Cold Current(NKCC). In this model, the circulation is driven by inflow-outflow condition and modified by local forcing. The solution is decomposed into inflow-outflow and local modes which describe only the effects of inflow-outflow condition and local forcing, respectively. Results of analyses show that both the surface cooling and positive wind stress curl are favorable for the separation of EKWC and formation of NKCC. This fact is compatible with the present knowledge about heat flux and wind stress field over the Sea of Japan.

  • Elasticity and softness of the skin depend on the level of moisture present in the stratum corneum, which is known to be affected by various environmental changes, such as cold and hot winds and dry environments. However, not many studies have been conducted on changes in skin moisture and the degree of recovery due to individual skin differences. In the present study, we aimed to investigate the effect of warm air heating on skin hydration levels and develop moisturizing formulas to improve lowered skin hydration levels. In order to deliver warm air heating condition, heating dryer (40 ℃, 6 m/s, 30 cm apart from forearm) was applied into inner forearm of healthy subjects (male: 10, female: 39, age: 25 - 63) Among 49 subjects, 26 subjects showed significantly lowered skin hydration levels until 30 min after warm air heating exposure (lowered group). In addition, moisturizing cream with high water holding capacity was applied to forearm of 10 subjects in lowered group for 3 weeks and skin hydration levels after warm air heating were significantly improved at the levels of before application of warm air heating. From this study, we found out that there is a skin type that skin hydration levels are significantly decreased under warm air heating condition (dehydrated skin) and this dehydrated skin can be improved by moisturizing formulas with high water holding capacity.

  • Background: The recent outbreak of the novel strain of influenza A (H1N1) virus has raised a global concern of the future risk of pandemic. Traditional Korean Medicine(TKM) has been combatting against contagious diseases and developed its own particular and efficient way in treating those diseases. Objectives: Provide a distinctive and effective TKM method in understanding the principles of treatment, prevention, and contraindications against influenza A through case histories. Method: We revised case histories of eminent doctors of Ming and Qing dynasties according to their clinical manifestations similar to those of influenza A. We also verified prescriptions of the "Dong-uibogam(東醫寶鑑)" through examining clinical practices of China today. Results: 1. The subtypes of Warm disease; Wind Warmth and Pestilence has the most similar clinical manifestation in comparison to Influenza A. Specifying these terms is important in recognizing and classifying various diseases under the name of Warm disease. 2. TKM considered not only external factors but also individual factors like general condition, diet, emotion, constitutional types, etc in the treatment of febrile diseases. 3. TKM developed a new way in the treatment of contagious diseases. considering the characteristics of each pathogen. TKM described the Warm pathogen being light as a feather, which enters through the nose, principally affecting the Lung. Therefore, they emphasized treatment with Pungent Sweet Cooling Moistening[辛甘凉潤] method. 4. As the conservation of fluid and humor is the primordial concern in the treatment of Warm disease, they restricted release of the exterior with pungent-warm and purgation method. The purgation methods was used exclusively to decrease fever and preserve fluid and humor. 5. The only differentiating characteristics of Influenza A with seasonal influenza are vomiting and diarrhea. Case research revealed the possibility of these manifestations to be a mechanism of restoration. 6. TKM provides alimento prevention method like Mint Pear Porridge, mung bean, and etc also combination of herbal medicine. Also emphasized in the conservation of essence for the prevention of contagious diseases. Conclusions: TKM developed its unique way in understanding the pathogenesis, diagnosis, treatment, and prevention of contagious diseases and formed its independent scheme of Warm Disease. This knowledge in febrile contagious disease is relevant today in providing diverse treatment and prevention for influenza A.

  • The persent study aims at finding out a means of prevention cool spell damages on the hilly areas. The irrigation plots of 24 hour stored water warm water way and warm water plots, cool water way are respectively established to find out water temperature and influnce on the growing rice plants. The results obtained are summed up as follows. 1. Warm water areas consisted of $5 m^2 Q=0.93 1{\ell}/sec$, V=31 cm/sec, S=1/1, 000, L=81.6m, B=5cm, h=6cm, t=4min 33sec, drops=9 areas, are constructed to help the water temperature of $14.5^{\circ}C$ rise to that of $21.6^{\circ}C$. This indicates lower temperature than $23^{\circ}C$ of critical water temperature in irrigation facilities by $1.45^{\circ}C$ and than $26.2^{\circ}C$ of balanced water temperature of Seoul arears by $4.6^{\circ}C$. But this does not give much influance on rice plant cultivation. 2. The rising of water temperature is influened according to the temperature, solar radiation but the water temperature changes according to the heat absorption of organized materials, weather and terraces. The difference of water temperature could be found in the first growing stage. 3. Through the warm water way of water rises to the temperature of $21.6^{\circ}C$ which also rises to the temperature of around $30^{\circ}C$ in the paddy field of submerged irrigation. The rice plants are comparatively free from prolonged cool damage, reproduction abstructive damage. 4. The water temperature in rice field in proportion to temperature influence of weather condition but the water temperature approaches to that of weather in the days of later growing stage and water temperature become lower than the air temperature in the fruit stage. 5. The water in the submreged field is $10^{\circ}C$ warmer than in the warm water way during the first growing stage period but the water temperature in the warm water way is warmer in the later growing stage period. The cool water of $14.5^{\circ}C$ is warmed to $30.1^{\circ}C$ and rice plants cultivation is free from other damages. 6. The 12% increased production or 570.98kg/10a is made cool water plot by rising the temperature of water from $14.5^{\circ}C$ to $21.6^{\circ}C$ making the water run through warm water way. 7. The damage inflicted by the cool water irrigation during the first growing stage period is the obstruction of peak tillering stage and the obstruction of heading the later growing stage period and the obstruction of fruiting and number of panides per fill.

  • The purpose of the study was to investigate the effects of economic hardship. parents'intro-eatrovert personality, and depression on parenting. The subjects were 487 seventh to ninth grade children and their parents. Data were collected through questionnaires. Children from which family experienced severe income loss perceived fathers'child-rearing attitudes as more warm/nurturant when fathers had extrovert personality. On the other hand, children under the worse paternal working condition perceived mothers'child-rearing attitudes as more warm/nurturant when mothers had introvert personality. The impacts of family income loss on mothers'rejecting/inconsistant child-rearing attitudes were exacerbated by its indirect effect through maternal depression.

  • In this study, we investigated how prescriptions from "Sanghallon(傷寒論)", such as Oryeongsan(五笭散), Banhasasimtang(半夏瀉心湯), Dohaekseunggitang(桃核承氣湯), Jukyeopseokgotang(竹葉石膏湯), were applicated in Onbyeongjobyeon(溫病條辦). When applying prescriptions from "Sanghallon" onto Onbyeong(溫病), Odang had replaced warm, dry herbs with cool herbs which generate body fluid, considering general characteristics of onbyeong that may easily dry up and injure body fluid. In the case of Seuponbyeong(濕溫病), however, warm, dry herbs were also used, as well. Odang did not persist in the general characteristic of onbyeong, but composed prescriptions only based on pathological condition. From this, one can point out his precise thinking of Byeonjeung(辯證), and pragmatic nature of his study.

  • The use of magnesium alloys meets the need of reducing weight of componests(especially in automotive and aerospace industry) keeping unmodified their mechanical properties. The adoption of magnesium alloys in sheet forming processes is still limited, due to their low formability at room temperature caused by the hexagonal crystal structure. In this study, the authors aim to understand the process condition which can lead to a successful improvement in the formability of a magnesium alloy(AZ31). Experiment and simulations of deep drawing were doned at various warm temperature for the blank and tool(holde and die)while the punch was kept at room temperature by cooling wale. in order to confirm that the deep drawing performance of magnesium alloy can be considerably enhanced with using the local heating and cooling technique.

  • Dampness is usually caused by the disorder of gi(氣) function, splenic dysfunction. It can be divided into exogenous and endogenous according to the route of invasion. The symptoms of dampness include heaviness of body and four limbs, heaviness of head like being bound, heaviness and lassitude of the whole body. Prescriptions for eliminating dampness are mostly composed of drugs that are aromatic, warm, dry, sweet and bland and can promote diuresis. This group of prescriptions tends to consume and impair body fluid. For this reason, they should be carefully used for patients with deficiency of eum(陰) and body fluid, or those who have weak constitution after illness. In order to select the right therapy for dampness, we must carefully analyze the state of dampness and the condition of healthy gi(氣), and distinguish the relationship between dampness and the healthy state of internal organs.

  • Precipitation forecasts from MM5 have been verified for the period 1989-2001 over Yeongdong region to show a tendency of model forecast. We select 57 events which are related with the heavy snowfall in Yeongdong region. They are classified into three precipitation types; mountain type, cold-coastal type, and warm type. The threat score (TS), the probability of detection (POD), and the false-alarm rate (FAR) are computed for categorical verification and the mean squared error (MSE) is also computed for scalar accuracy measures. In the case of POD, warm, mountain, and cold-coastal precipitation type are 0.71, 0.69, and 0.55 in turn, respectively. In aspect of quantitative verification, mountain and cold-coastal type are relatively well matched between forecasts and observations, while for warm type MM5 tends to overestimate precipitation. There are 12 events for the POD below 0.2, mountain, cold-coastal, warm type are 2, 7, 3 events, respectively. Most of their precipitation are distributed over the East Sea nearby Yeongdong region. These events are also shown when there are no or very weak easterlies in the lower troposphere. Even in the case that we use high resolution sea surface temperature (about 18 km) for the boundary condition, there are not much changes in the wind direction to compare that with low resolution sea surface temperature (about 100 km).
