Objectives : The purpose of this study is to explore the trends of Korean medical study on stress in the industrial worker. Methods : We received numbers of the studies about stress in the industrial worker from 6 Korean web databases, using key words such as ‘Industry AND Stress’, ‘Oriental medicine AND Stress’, ‘Worker AND Stress’, ‘Workplace AND Stress’. We received 12 research papers and they were analyzed and the journals, the authors, the contents of 3 classification of those research papers. Results : Among them, we had 6 reviews of Dept. of preventive medicine and Dept. of third medicine, college of Korean Medicine, Won-kwang University, and the rest of them were 6 reviews. We had 4 reviews of Korean Journal of Oriental Preventive Medical Society, 2 reviews of the Journal of Traditional Korean Medicine, 2 reviews of Journal of Oriental Neuropsychiatry and so on. According to the contents of reviews, we had 7 reviews of correlation of industrial worker and stress, 4 reviews of cause on the industrial worker’s stress and 1 case report. Conclusions : We reviewed the trends of Korean medical study on stress in the industrial worker. The stress in the industrial workers were related with the type of occupation, social psychology, drinking, smoking, the satisfaction of job, the harmony of organization.And we knew that the musculoskeletal pain was related to the industrial worker’s stress. In the future, abundant case studies, follow-up trials and RCTs should be done about the industrial worker’s stress.

Purpose: Intracranial manifestations associated with autosomal dominant polycystic kidney disease (ADPKD) include arachnoid cysts, dolichoectasias, and subdural hematoma (SDH), although there are only a few reports of SDH in patients with ADPKD. We report a case of spontaneous SDH in a patient with ADPKD. A 33-year-old woman complained of severe nausea and vomiting for 10 days. She had suffered from a headache for several months. She was diagnosed with ADPKD and hypertension 6 years earlier, and the hypertension was well controlled. Her mental state was drowsy in the emergency room. Her blood pressure was 180/105 mmHg. There was no evidence of head trauma. Results of a peripheral blood CBC and blood chemistry analysis were within normal limits, as were the results of a blood coagulation test and urinalysis. She was pregnant and in the eighth week of gestation. Brain magnetic resonance imaging revealed SDH in the left lateral convexity and focally in the right lateral convexity, and brain herniation. Surgical drainage was performed through a burr hole, under general anesthesia. Intra-operatively, 62 mL of liquefied subdural hematoma were removed. She recovered completely without sequelae.

<P>Nanocrystalline Bi5Ti3FeO15 layered perovskite exhibiting Aurivillius phase was synthesized by polymerized complex (PC) method and investigated for its physico-chemical as well as optical properties. The crystallization of Bi5Ti3FeO15 synthesized by PC method was found to occur in the temperature range of 800-1050 degress C, whereas the single crystalline Bi5Ti3FeO15 formed at 1030 degrees C by solid state reaction (SSR) method. The observation of highly pure phase and such lower crystallization temperature in Bi5Ti3FeO15 prepared by PC method, is in total contrast to that observed in Bi5Ti3FeO15 prepared by the conventional solid-state reaction (SSR) method. The band gap of nanocrystalline Bi5Ti3FeO15 determined from UV-Vis diffusion reflectance spectrometer was 2.38 eV (525 nm). The photocatalytic activity of Pt/Bi5Ti3FeO15 prepared by PC method was investigated with the photodecomposition of isopropyl alcohol (IPA) and hydrogen production from water-methanol mixed solution under visible light (lambda > or = 420 nm). The respective activities for PC sample were higher than that of Pt/Bi5Ti3FeO15 prepared by SSR as well as Pt/TiO(2-x)N(x).</P>

In this paper, we present the method that improve alarm security system using the electronic circuits added the emergency lamp by our proposed Algorithms. In conventional method the emergency lamp of warning & alarm system didn't work perfectly its performance because of battery with short life. For improving this problem we, using Periphera1 Interface Controller IC, designed the circuit added the emergency Samp for an warning & alarm system and for prevention against stopping the electric current, and compared our proposed method with conventional method.<br/> By designing the circuit to stop up over charge we can extend life of battery, use for a stoppage of electric current in emergency and according to the lightness around. Therefore we are very convenient and profitable in our life.<br/> In the future we will study the method to lower the cost of architecture for practical utilization.

Background/Aims: Follicular thyroid carcinoma (FTC) and Hurthle cell carcinoma(HCC) of the thyroid are relatively uncommon thyroid malignancies in iodine-sufficient areas. In this study we evaluated the clinical behavior, prognosticfactors and treatment outcomes of FTC and HCC in Korea. Methods: This multicenter study included 483 patients with FTC and 80 patientswith HCC who underwent an initial surgery between 1995 and 2006 in one of thefour tertiary referral hospitals in Korea. We evaluated clinicopathological factorsassociated with distant metastases and recurrence during a median of 6 years offollow-up. Results: HCC patients were significantly older (49 years vs. 43 years; p < 0.001) andhad more lymphovascular invasions (22% vs. 14%; p = 0.03) compared with FTCpatients. Distant metastases were confirmed in 40 patients (8%) in the FTC groupand in two patients (3%) in the HCC group (p = 0.07). Distant metastases weresignificantly associated with older age, widely invasive cancer and extrathyroidalinvasion. Only 14 patients (3%) had recurrent disease and there was no significantdifference between FTC and HCC groups (p = 0.38). Recurrence was associatedwith larger tumor size and cervical lymph node metastasis. Conclusions: HCC patients were older and had more lymphovascular invasionsthan FTC patients. However, FTC and HCC patients had similar initial clinicopathologicalfeatures. Older age, wide invasiveness and extrathyroidal invasionwere independent risk factors for predicting distant metastases in FTC and HCCpatients.

Highly pathogenic avian influenza virus (HPAIV) damages vital organs and tissues, frequently leading to death in birds, and causes serious economic losses in the poultry industry. In addition, HPAIV can infect humans and other mammals, often with fatal outcomes. In this study, the virucidal efficacy of Clean-Zone??, which contains citric acid, malic acid and phosphoric acid, against avian influenza virus (AIV, H9N2) was investigated. Virucidal efficacy was determined by examining the viability of AIV after contact with the disinfectant in the allantoic membrane of chicken embryos. The disinfectant and AIV were reacted under hard water (HW) and organic matter suspension (OM) condition. AIV was inactivated with 200- and 50-fold dilutions of the disinfectant under HW and OM conditions, respectively. As the disinfectant, Clean-Zone??, has a virucidal efficacy against AIV, it can be used to prevent the spread of animal viral diseases.

To identify the inheritance and stability of T5 progeny tomatoes by Agrobacterium-mediated transformation, transgenic tomato plants were selected by NPT II and CP genes. Both Southern and Northern blot analyses confirmed that T5 progeny transgenic tomatoes were for the CP gene. TMV resistance and horticultural characteristics of the transgenic tomatoes were analyzed. Self-pollinated progenies of each transgenic plant were planted. The transformation of four selected T4 tomatoes was confirmed by Southern blot analysis for genomic DNA. Two lines of T5 and 1 line of T1 tomatoes showed RNA expression by Northern blot analysis. T5 progeny transgenic tomatoes with TMV resistance showed lower ELISA (enzyme-linked immunosorbent assay) value than cultivar Seokwang for control. Between transgenic and non-transgenic plants, there were no significant differences in horticultural characteristics. TMV 저항성 형질전환토마토의 후대 T5세대에서 TMV저항성과 안정성을 확인하였다. 형질전환된 토마토의 잎을 채취하여 T4세대의 DNA와 T5 세대에서 RNA를 분리정제하여 안정적으로 유전되고 발현됨을 확인하였다. 또한 이들에 대한 TMV저항성을 확인한 결과 3계통 중 2계통은 저항성이었으나 1계통은 그렇지 않았다. 따라서 유기시킨 형질전환체가 모두 다 저항성을 갖는 것은 아님을 알 수 있다. 또한 후대 T5세대에서의 원예적형질을 비교해본 결과 형질전환체와 비전환체사이에 뚜렷한 차이를 볼 수 없었다.
