Objective: Occupational medicine specialists in the Busan, Ulsan and Kyung-Nam areas established an area-based occupational disease surveillance system and used this system to collected case information for the purpose of preventing occupational diseases Methods: l l hospital participated in this system. The authors selected five main diseases, which were hand-arm vibration syndrome (HAVS), work-related musculoskeletal disorder (WRMSD), occupational asthma, occupational skin disease and occupational and occupational lung cancer and established their case definitions. All cases were reported on the web, and real time analysis was conducted. Results: Between April 2001 and April 2003, 192 cases of HAVS, 118 cases of WRMSD, 33 cases of occupational asthma, 17 cases of occupational skin disease and 17 cases of occupational lung cancer (for a total of 377 cases of these five main diseases) were reported. most of the HAVS cases came from shipbuilding, and 172 of them (92.7%) were associated with grinding. Of the four main types of WRMSD, carpal tunnel syndrome (CTS) was the most prevalent with 46 cases and shipbuilding was also the main industry involved (83.9%). The ergonomic risk factors involved mainly associated with the hand. In 19 (57.6%) and 4 (12.1%) cases of occupational asthma, the agents involved. The causative agents of occupational lung cancer included Cr, welding fume, PAH, Ni, etc. 10(58.8%) of the cases were diagnosed as squamous cell carcinoma and 5(29.4%) as adenoma. Conclusion: This result showed that an area-based occupational disease surveillance system might provide an effective method of evaluating the prevalence of such diseases, however the Busan, Ulsan and Kyung-Nam provinces are too large to be treated as individual areas. Therefore, the authors suggest that each province should establish its own surveillance system.

Korea, a total number of 19,758 stool specimens were collected from the inhabitants who lived in the basins of main 6 rivers, i.e. the Han River, the Gum River, the Nakdong River, the Mangyong River, the Yongsan River and the Seomjin River. The specimens were examined both by cellophane thick smear method and Stoll's egg counting technique during the period from March 1973 to October 1982. The distribution and infection rates were compared in those of river and non-river sides, and the epidemiological statrs was analysed statistically by the regression equations and catalytic curves with the results obtained from two endemic areas. The results are as follows: 1. High egg positive rates were revealed among the inhabitants in the areas of all above river basins, whereas low egg positive rates were obtained among the inhabitants in the areas apart from the riversides. However, in some areas which are not directly connected with the rivers, relatively high rates of Clonorchis infection were also observed. 2. The infection rates of Clonorchis sinensis by sex age were shown significantly different among the population in the most of these studied areas. The rates for males were significantly higher than that for females, and the rates were increased by the higher age groups up to 40 to 59 years old. However in the high endemic areas such as Kimhae the infection rates of both sexes were almost parallel and practically similar high rates revealed in all age groups for 20 to 60 years old. 3. The mean E.P.G. count of Clonorchis infection in the surveyed areas was found higher in the areas which shown as higher infection rates. The degree of the intensity of Clonorchis infection by E,P.G. counts was evenly distributed to heavy and very heavy infections as well light and moderate infections in the areas showed high infection rates. 4. The intensity of endemicity in all surveyed areas was compared with the regression equations calculated with the cumulative percentages of E.P.G. counts. 5. For the quantitative analysis of epidemiology of clonorchiasis in Kimhae and Pyongtrek areas, special type of simple catalytic model was applied to the age prevalence rates revealed through stool examination for Clonorchis eggs and intradermal test for the detection of positive reactors. 6. It was suggested that the two-stage catalytic was well fitted to the prevalince rates by sex and age in the egg positive cases in Kimhae and Pyongtaek areas, and the calculation lead to the equation y=1.042(e-^(0.003t)-e^(-0.074t), a=0.074〉b=0.003 in Kimhae area, and y=1.412(e^(-0.024t)-e^(-0.041t), a=0.024〈b=0.041 in Pyongtaed area. 7. In the high endemic area such as Kimhae, the tendency of familial aggregation was not recognized by statistical analysis. In this area, the mean E.P.C. obtained from same persons in 1973 were compared and descussed statistically.

This study aims at revealing the physiological responses of dehydration (DH) and rehydration (RH) in intermittent exercises at the work intensity of 70% HR max. First, with general student public, three times of exercise (each for 20 minutes) at the given work intensity were taken, with a break for 25 minutes respectively. Their heart rate, rectal temperature and plasma electrolyte concentration both DH and RH were measured. Second, in two groups of athletes and non-athletes, 9 rounds of exercise (for 100 minutes) and 8 breaks (for 60 minutes) were taken, with RH forced 10 times to compensate for the subjects' water loss. Their change in sweat loss and plasma electrolyte concentration as well as the IVDP(Intensive Voluntary dehydration Phenomenon) were experimented. The summary of this research follows. 1) Mean heart rate and rectal temperature in intermittent exercises were higher at DH than at RH, growing up at the increasing level of DH. 2) RH saw no change in the plasma concentration of Na+, K+ and Cl-, while DH observed a significant increase. 3) HCO₃made a significant decrease at DH before growing up. 4) Mg++ had no change, while Ca++ increased significantly at RH and DH. 5) Lactate showed an increase with significance at RH and DH, especially greater at DH. 6) Osmotic pressure increased meaningfully at DH. 7) Anion gap increased significantly at DH and RH. 8) On the other hand, when the forced RH was held, the group of athletes had greater sweat loss per body surface area than that of non-athletes. 9) The athletes' plasma concentration of Na+ and Cl- revealed a clear decrease. 10) There was seen no significant change in the plasma concentration of K+, Mg++ and Ca++ in both groups. 11) The IVDP occurred at the RH of 2.3ℓfor athletes and more than 2.5ℓfor no-athletes.

Behcet`s disease is a multisystem in. ammatory condition and is a vasculitis syndrome with a wide array of clinical manifestations. The most frequent vascular lesions are veins such as vena cava. Superior vena cava occlusion results in the development of mediastinal collateral vessels into the esophageal veins, and then into the coronary vein, hepatic vein, and inferior vena cava, giving rise to a downhill varix [1]. Thus, it could cause esophageal and bronchial varices. Until now, there has been only one report in South Korea of a patient with bronchial varix presenting hemoptysis, and no report of bronchial varix in a patient with Behcet`s syndrome. Reported herein is a case of a 64-year-old male patient with hemoptysis who was subsequently diagnosed as having a bronchial varix due to SVC occlusion in Behcet`s syndrome.

거풍광산 주변 밭의 오염된 중금속을 토양오염공정시험법과 TCLP를 이용하여 분석한 결과 비소, 납, 카드뮴, 구리, 아연과 같은 중금속의 농도가 전국 토양 평균치를 초과하는 것으로 나타났다. 본 연구에서는 중금속 오염된 토양의 안정화를 위해서 구연산칼슘인산염 용액을 이용하는 방안에 대한 기초연구를 실험실 조건과 현장 조건에서 수행하였다. 실험실 조건에서 구연산칼슘인산염 용액을 투여한 실험 결과, 고압멸균처리한 반응조에 비해 토착미생물 군집이 존재하는 반응조에서 용존 인산염의 농도가 현격히 감소하였으며, 중금속 안정화율도 높다는 것을 확인하였다. 현장 실험에서도 구연산칼슘인산염 용액 투여가 용존인산염 감소와 중금속 안정화 결과를 가져왔다. 이는 미생물의 인산염 사용이 중금속 안정화 향상에 도움이 되었음을 의미한다. 현장 실험에서 미생물군집을 분석한 결과, 구연산칼슘인산염 용액 투여로 다양성이 증대되었으며, Anaerofilum과 Treponema같은 혐기성 미생물 개체가 우점종으로 발현되는 결과를 얻었다. 이러한 결과들을 살펴볼 때, 구연산칼슘인산염의 투여로 인한 토착미생물 신진대사 활성화를 통해서 토양 내 혐기성 환원 조건을 제공하거나 토양미생물이 인산염을 중금속 안정화에 이용되기 쉽게 도와주는 미지의 기작을 통해서 해당 현장의 중금속 안정화에 기여한 것으로 해석된다. A farming area located near an abandoned copper mine in GuPo-ri, Choongchung province is heavily contaminated with heavy metals such as As, Pb, Cd, Cu and Zn of which concentrations are higher than the values typically detected in Korean soil environment. In this work, laboratory and field studies were conducted to examine feasibility of using Ca-citrate-phosphate solution in stabilizing heavy metals in the polluted soils. In laboratory batch experiments with field soil, the addition of Ca-citrate-phosphate solution resulted in decrease of aqueous phase concentration of phosphate and improvement of heavy metal stabilization, compared to those for sterilized soil samples. This indicates that microbial uptake of phosphate may have provided positive effects on availability of phosphate toward heavy metal stabilization. According to microbial community analysis for the field experiment, the use of Ca-citrate-phosphate led to increased diversity of microbial populations, and strict anaerobic microorganisms such as Anaerofilum and Treponema became the most dominant populations in the solution-amended field experiments. These findings suggest that, when Ca-citrate-phosphate is used for heavy metal stabilization in soils, microbial processes may have important roles in improving the stabilization of heavy metals by providing reducing conditions to the treatment locations or/and by making phosphate available to heavy metal stabilization.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging disease characterized by fever and thrombocytopenia. Haemaphysalis longicornis ticks comprise the major population of ticks in the environment and have been considered as the main vector for SFTS virus (SFTSV). Here we investigated the distribution of ticks carrying SFTSV collected from the environment using the dragging or sweeping methods during April∼October 2015 in Jeollanam-do, Korea. Sampling was taken from Songjeong, Omi, Bangkwang, Sandong areas in Jiri walking trails. Among the total 3,869 ticks collected, 3,823 ticks (98.8%) were H. longicornis, 41 (1.1%) were Amblyomma testudinarium, and 5 (0.1%) were Ixodes nipponensis. Classification results by regional groups of H. longicornis indicated that 1,613 ticks were collected in Sandong, 1,190 ticks in Omi, 603 ticks in Bangkwang, and 417 ticks in Songjeong. In monthly distributional studies of H. longicornis based on the developmental stages, nymph (325 ticks) was collected from May to October, 94% of larvae from April to June, and 94% of adult from June to August. These results showed the different dominant stage of ticks according to seasons. However, no SFTSV-specific gene was detected in 3,823 ticks of H. longicornis, 41 of A. testudinarium and 5 of I. nipponensis.

3-D Topology Optimization Based on Nodal Density of Divided Sub-elements for Enhanced Surface Representation

Song, Joon-Hyun,Kim, Cheol 한국정밀공학회 2012 International Journal of Precision Engineering and Vol.13 No.4

The material distribution based on an element density is adequate for most of 2-D topology optimization problems. However, in 3-D topology optimization it is usually difficult to obtain a smooth topological configuration and a virtual connectivity phenomenon easily appears in a low-density domain. A 3-D structural topology optimization and novel surfacesmoothing scheme based on SIMP (solid isotropic microstructure with penalization) and sub-element bilinear interpolation has been developed using node densities and a corresponding computer program was written in order to validate the proposed method. Compared to a common element density method, the proposed method resulted in more enhanced smooth surfaces of optimum topology designs. To show the usefulness of the method, three examples of 3-D structural topology optimizations were illustrated.

Background. It is important for the medical providers who work in the emergency department to have the adequate knowledge about the nature and the ways to deal with the patients who suffer from domestic violence because in our country the management of them is primarily performed at the emergency centers. The purpose of this study is to provide basic data about the domestic violence and to help in developing the education and management model for the medical providers. Methods. The authors retrospectively reviewed the medical records of 198 patients who visited the emergency center of Chunchon Sacred Heart Hospital from July 1997 to August 1998. Results. The violence against the spouses was highest(108 cases:54.5%) and most of the victims were female(92%) in those cases. The violence against children younger than age 3 was 30%. The majority of the victims were arrived around noon(54.5%) and among them, the aged and children were more concentrated. The degree of injury was severer than that of the victims of general violence. Conclusion. In this study the violence against the spouses was the highest in incidence and against the aged was the lowest. The violence rate against children younger than age 3 was lower than that of other comparable studies. The incidence of sexual violence was significantly lower than that of other countries. The degree of injury was generally severer than that of general violence patients. But these result should be carefully criticized and accepted because up to now the system for the detection and management for them is not well established.
