Objectives : The purpose of this paper is to report the effect of Korean medicine treatments on allergic contact dermatitis aggravated after applying steroid ointment. Methods : We treated a 63-year-old woman with allergic contact dermatitis on the both forearm, jaw, neck, chest with Korean medicine. Before Korean medicine treatments she has taken oral steroids and applied steroid ointment for several years to treat dermatitis, but long-tern steroid therapy aggravated her symptoms like skin pruritus, erythema, exudates or edema. After Korean medical treatment for 27 days, we found that the size of erythema was reduced, and symptoms like pruritus, exudates and edema were lost. We recorded pictures of changes on symptoms. Results & Conclusions : The symptoms of allergic contact dermatitis were improved. Erythema, edema, exudate were lost. Thus Korean medicine treatments are effective on allergic contact dermatitis and could be a great alternative to steroid treatment.

Static CAD models are the CAD models that do not have feature information and modeling history. These static models are generated by translating CAD models in a specific CAD system into neutral formats such as STEP and IGES. When a CAD model is translated into a neutral format, its precious feature information such as feature parameters and modeling history is lost. Once the feature information is lost, the advantage of feature based modeling is not valid any longer, and modification for the model is purely dependent on geometric and topological manipulations. However, the capabilities of the existing methods to modify static CAD models are limited, Direct modification methods such as tweaking can only handle the modifications that do not involve topological changes. There was also an approach to modify static CAD model by using volume decomposition. However, this approach was also limited to modifications of protrusion features. To address this problem, we extend the volume decomposition approach to handle not only protrusion features but also depression features in a static CAD model. This method first generates the model that contains the volume of depression feature using the bounding box of a static CAD model. The difference between the model and the bounding box is selectively decomposed into so called the feature volume and the base volume. A modification of depression feature is achieved by manipulating the feature volume of the static CAD model.

Objectives: The objective of study was to calculate the municipal level environmental burden of disease (EBD) due to heat wave. Methods: The data used were Korea National Health Insurance 2011 claim data and 2011 death registry. Heatwave related diseases included hypertensive heart diseases, ischemic heart diseases, cerebrovascular disease, and heat related illness. According to the method that WHO proposed, the study computed population-attributable fraction with relative risk which come from previous study and proportion of exposure which the study calculated with historical meteorology data. Results: The Average of 251 municipal EBD was 2.11 per thousand persons. The value of years lost due to disability was 11 times higher than that of years of life lost. On average EBD of county and southern geographical areas tended to be higher than those of District or city areas. The relationship between municipal deprivation index (composite deprivation index) and EBD showed the positive association, which means that the worse deprived municipal is, the higher EBD takes. Conclusions: Climate change is getting one of the major risk factors of cardio-cerebrovascular disease, which is the second leading cause of death. The study results suggested the urgent policy planning and reaction of climate change adaptation.

The central problem of purchasing houses is choice, which is accompanied by perception of risk. Perceived risk is defined as a risk perceived by a consumer subjectively in choice situations. The components of perceived risk are uncertainty and consequence. There are seven types of perceived risk in purchasing houses. Those are financial risk, functional risk, social risk, psychological risk, physical risk, time risk and future opportunity lost risk. The empirical survey about comsumer's purchasing Public Apartment suggests : 1) In general, rspondents perceive relatively high risk in purchasig Public Apartment. 2) Of seven risk types, financial, functionalm, future opportunity lost, time, and social risk correlate highest with overall perceived risk and explain the variance of it. 3) Physical and psychological risks don't correlate significantly with overall perceived risk. From the findings in empirical analysis, consumers are recommended to device riskreduction activities in purchasing Public Apartment. 1. Active information search is needed in purchasing Public Apartment in order to reduce overall perceived risk. 2. Housing concept should change from ownership to rental thinking. 3. Consumers should be accustomed to Housing Loans by bank. 4. Purchasing goals should be established clearly before purchasing houses. 5. Careful deliberation is required and informations from personal sources are useful.

Decomposition of Zizania latifolia was investigated with litterbag method for 13 months from November in 1998 to December in 1999, at the fringe of stream at Boryeong, Chungnam Province in Korea. After 13 months, remaining mass of leaves, culms and rhizomes was 16.9, 14.7, and 10.1%, respectively. Mass loss of the rhizomes was higher than those of the leaves and culms. The decay rate of leaves, culms and rhizomes was 1.86, 2.00 and 2.36 per year, respectively. Initial concentration of N, P, K, Ca, and Mg of leaves, culms and rhizomes was 18.0, 14.5, 44.0 mg/g for N,0.18, 0.12, 0.67 mg/g for P, 14.1 ,14.2, 14.8 mg/g for K,3.6, 1.5, 0.3 mg/g for Ca, 1.1, 0.5, 0.5 mg/g for Mg, respectively. Concentrations of N and P in rhizomes were higher than those in leaves and culms. Except for Mg in rhizomes, there was no immobilization period during the decomposition. Most of the N, P and Mg were lost during the first 3 months. In case of K and Ca, most were lost within 1 month.

The purposes of this syudy were to identify the factors of perceived risk, satisfaction, and intention on rental clothing. The subjects were 767 adults residing in Jeonbuk province. The research was made from February 20 to March 19, 2003. Fof data analysis. frequencies, percentages, mean, and standard deviations were calculated. Also, factor analysis and stepwise multiple-regression analysis were done. The results were as follows: 1. Approximately half of the respondents had experiences of rental clothing, and the most frequent items were wedding dress, degree gown, performance dress, and sports wear in descending order. 2. The factors of perceived risk of rental clothing were divided into lost, appropriateness, and damage, and total variance was 62.51%. The perceived risk about damage of rental clothing was the highest, and lost was the lowest. 3. The factors of rental clothing satisfaction were divided into appearances, store status, function, and fitness, and total variance was 59.96%. The satisfaction of function of rental clothing was the highest, and the store status was the lowest. 4. The intention on rental clothing was high in case of higher interest in rental clothing, higher educational level. more experiences in rental clothing, lower perceived risk of damage on the rental clothing, and younger person, and these variables explained 54.00% of the intention on rental clothing.

Objectives : The aim of the study was to estimate the annual socioeconomic cost of diseases in Korea. Methods : We estimate both the direct and indirect costs of diseases in Korea during 2003 using a prevalence-based approach. The direct cost estimates included medical expenditures, traffic costs and caregiver's cost, and the indirect costs, representing the loss of production, included lost workdays due to illness and lost earnings due to premature death, which were estimated based on the human capital theory. The cost estimates were reported at three different discount rates (0, 3 and 5%). Results : The cost of diseases in Korea during 2003 was 38.4 trillion won based on 0% discount rate. This estimate represents approximately 5.3% of GDP The direct and indirect costs were estimated to be 22.5 trillion (58.5% of total cost) and 15.9 trillion won (41.5%), respectively. It was also found that the cost for those aged $40\sim49$ accounted for the largest proportion (21.7%) in relation to age groups. The cost of diseases for males was 23.5% higher than that for females. For major diseases, the total socioeconomic costs were 16.0, 13.4, 11.3 and 11.19% for neoplasms, and diseases of the digestive, respiratory and circulatory systems, respectively. Conclusions : This study can be expected to provide valuable information for determining intervention and funding priorities, and for planning health policies.

S plastic injection molding factory located at Namdong Industrial Complex in Incheon produces plastic parts for semiconductor, vacuum cleaners, office furniture, etc. It produces the parts to customers' order and delivers them directly to customers at due dates using the trucks of freight company. In recent years, it has been suffered from the excessive production cost, high lost sales rate, rigid response to customers' order, and high delivery cost, which affect negatively on its profit. This paper introduces a case study on the profit increase through a newly proposed production and distribution method which applies a make-to-stock and multi-visit delivery strategy at S plastic injection molding factory. The proposed method is evaluated by comparing with the current method with respect to sales profit using the historical data of customer demand. It is confirmed through the computational experiments that the proposed production and distribution method yields almost double increase in profit resulted from the increased production, reduced lost sales, reduced production cost, and reduced delivery cost.
