무안지역의 양파 농가에서 육묘 재배가 시작된 2013년 9월 중 하순경부터 본밭에 정식이 이루어진 11월 하순까지의 온도 및 상대습도 조건이 양파 노균병 발병에 적합한 환경에 해당하였다. 그래서 육묘 단계에서 발생하는 양파 노균병의 방제를 위해 살균제를 이용하여 연구를 수행한 결과, 양파 육묘상에 서로 다른 살균제들이 처리된 각각의 처리구에 비해서 무처리구에서는 51.1%의 이병주율을 보여 살균제 효과를 평가하기에 충분하였다. 다양한 작용기작을 가지고 있고 포자발아 억제 효과가 우수하여 보호살균제로 많이 사용되고 있는 mancozeb을 세 차례 살포한 MAN 처리구의 이병주율이 4.4%로 나타나 방제가가 91.4%로 조사되어 가장 우수한 방제 효과를 보였고, 작용기작이 각각 다른 살균제인 amectotradin+dimethomorph, fluopicolide+propamocarb HCl, dimethomorph+pyraclostrobin을 순서대로 살포한 MIX 처리구는 10.0%의 이병주율을 보여 방제가가 80.4%로 나타났다. 그리고 amectotradin+dimethomorph만을 세 차례 살포한 AME+DIM 처리구는 12.2%의 이병주율을 보여 방제가가 76.1%로 나타나 방제 효과가 다른 두 처리구에 비해 다소 낮게 나타났으나 살균제가 처리된 모든 처리구에서 무처리구에 비해서 통계적으로 유의한 차이를 나타내었다. 따라서 양파 육묘 재배 시기가 노균병발병에 적합한 환경에 해당되므로 살균제 등을 사용하여 육묘 단계부터 양파 노균병 방제에 대한 적극적인 노력이 필요하다고 생각한다.

To compare differences of LOS between the group of inpatients via referral centers(the referral group) and the group of inpatients via different routes (the general group) and analyze factors which determine the difference. The 9,484 cases of newly inpatients of Mar., Jun., Sep., Dec. of year 2003 were used for the data. We calculate the Case-mix index of length of stay($CMI_{LOS}$) to compare LOS adjusted with the disease as the ratio of a patient' LOS to all patients' average LOS by 21 classification diagnosis group. We conducted t-test to compare differences of $CMI_{LOS}$ between two groups and multiple regression to analyze factors determining the difference. $CMI_{LOS}$ was 0.94 in the referral group, which was smaller than 1.01 in the general group. LOS was 7.5days in the referral group, which was 0.6day shorter than that in the general group. Multiple regression also showed that $CMI_{LOS}$ was smaller in the referral group than in the general group after controlling patients' general characteristics, diagnostic information variables. The referral centers can be said to playa role in decreasing LOS. We suggest that variety of depth studies on referral centers should be continued at the strategic level of hospital management using additional medical informations.

Background: Rehabilitations in subacute phase are different from acute treatments regarding the characteristics and required resource consumption of the treatments. Lack of accuracy and validity of the Korean Diagnosis Related Group and Korean Out-Patient Group for the acute patients as the case-mix and payment tool for rehabilitation inpatients have been problematic issues. The objective of the study was to develop the Korean Rehabilitation Patient Group (KRPG) reflecting the characteristics of rehabilitation inpatients. Methods: As a retrospective medical record survey regarding rehabilitation inpatients, 4,207 episodes were collected through 42 hospitals. Considering the opinions of clinical experts and the decision-tree analysis, the variables for the KRPG system demonstrating the characteristics of rehabilitation inpatients were derived, and the splitting standards of the relevant variables were also set. Using the derived variables, we have drawn the rehabilitation inpatient classification model reflecting the clinical situation of Korea. The performance evaluation was conducted on the KRPG system. Results: The KRPG was targeted at the inpatients with brain or spinal cord injury. The etiologic disease, functional status (cognitive function, activity of daily living, muscle strength, spasticity, level and grade of spinal cord injury), and the patient's age were the variables in the rehabilitation patients. The algorithm of KRPG system after applying the derived variables and total 204 rehabilitation patient groups were developed. The KRPG explained 11.8% of variance in charge for rehabilitation inpatients. It also explained 13.8% of variance in length of stay for them. Conclusion: The KRPG version 1.0 reflecting the clinical characteristics of rehabilitation inpatients was classified as 204 groups.

Warm disease: Any of various heat disease characterizer by rapid onset and shifts, pronounced heat signs, and a tendency to form dryness and damage yin. Exterior heat sign: exterior heat patterns are characterizer by pronounced heat signs, such as a red sore pharynx and a relatively red tongue with dry fur, the pulse is floating and rapid, cough and the production of thick white or yellow phlegm. If wind-heat evil exist in weifen, it becomes exterior syndrome, and a remedy about that is dispelling wind-heat but when wind-heat evil invades in nasal and throat part so the disease occurs, you need to add relieving sore throat worsens invades in lung it makes disharmony of diffuse in lungs. So a remedy about it is diffuse the lung. disharmony of diffuse in lungs makes metabolic disorder of qi and liquid and humor malfunction therefore it occurs cough and heat-phlegm syndrome. heat from weifen invades the whole of lungs and form lung heat. So a remedy about lung heat is clearing away lung heat, this lung heat makes inevitably bleed in lungs, therefore a remedy in this case is clearing the lung to stop bleeding, or moistening the lung. Exterior heat sign means that exterior syndrome coexists with heat syndrome and it means that a remedy of this syndrome need to mix prescriptions for relieving exterior syndrome and heat-clearing prescriptions to treat this syndrome.

The purpose of this study was to evaluate the general features of allergic patients in northwestern Chungcheongnamdo who visited Soonchunhyang University Cheonan Hospital. The subjects in this study were 1692 suspected allergic patients. After their allergic symptoms were checked and a MAST-CLA test was conducted, the following results were obtained: 1. The mean age of the subjects was 23.1 years old. The male patients represented 56.2% and the female patients accounted for 43.8%. 1387 (82.0%) patients of those investigated suffered from allergic disease. 2. Among the 1387 patients, 1022 (73.7%) patients showed an increased total IgE level. The positive rate of those who were in their 40s (87.0%) was the highest, but their age made no difference to their positive rate of total IgE. 3. Concerning the positive rate for allergen specific antibody by age, those who were in their teens (73.5%) topped the list and similar in all age group except in their 40s. By gender, the positive rate of the male and female were 56.3% and 43.9% respectively. Regarding the positive rates by allergic disease, those who suffered from allergic rhinitis (60.4%) were most vulnerable, followed by the patients with allergic dermatitis (47.4%), with bronchial asthma (47.2%) and with urticaria (39.4%). 4. As for seasonal positive rates, they were most susceptible in April (77.2%) and May (71.1%). We discovered a significant difference according to seasons; Spring (60.1%), Winter (45.4%) and Summer (39.2%). 5. In case of Korean inhalent panel, the most dominant allergen-specific antibodies were "Cockroach mix" (31.1%), followed by "D. pteronyssius" (23.8%) and "Dog" (14.3%). In the event of food panel, the most popular allergen-specific antibodies were "D. farinae" (25.0%), followed by "D. pteronyssinus" (19.8%) and "Hose dust" (12.0%). 6. The residential type made no difference to the positive rates of "House dust", "Cockroach mix" and "Dog" as major antigen but compared with others, positive rates for "Tick" were somewhat higher in apartment buildings.

Backgrounds : Taiwan has similar national health insurance (NHI) system for traditional medicine with South Korea. Recently, new quality improvement policies for traditional medicine is being attempted in Taiwan. Objectives : This study aimed to review the Taiwanese NHI system for Chinese Medicine (CM) and introduce quality improvement policies. Methods : Research articles, reports, government publications and year books which handled traditional medicine system and NHI system in Taiwan were searched and collected. The authors analyzed and summarized the contents in a qualitative manner. Results : In Taiwanese NHI system, CM procedures and medication for outpatients are reimbursed through a mix of fee-for-service and global budget payment system. CM shares 4% of total expenditure of NHI in Taiwan. Mostly, the expenses for procedures are reimbursed regardless of disease type, however, in the specialized program for quality improvement, CM doctors have to comply with standard operating procedures (SOPs). Conclusions : Taiwanese NHI system implemented SOP-based new reimbursement system for CM. Yet, the scientific evidences for SOPs are not sufficient, it can be useful references when we develope disease related reimbursement system for Korean Medicine in South Korea.

Salmonellosis is a highly contagious bacterial disease that threatens both human and poultry health. Tests that can detect Salmonella in the field are urgently required to facilitate disease control and for epidemiological investigations. Here, we combined loop-mediated isothermal amplification (LAMP) with a chromatographic lateral flow dipstick (LFD) to rapidly and accurately detect Salmonella. LAMP primers were designed to target the Salmonella invA gene. LAMP conditions were optimized by adjusting the ratio of inner to outer primers, $MgSO_4$ concentration, dNTP mix concentration, amplification temperature, and amplification time. We evaluated the specificity of our novel LAMP-LFD method using six Salmonella species and six related non-Salmonella strains. All six of the Salmonella strains, but none of the non-Salmonella strains, were amplified. LAMP-LFD was sensitive enough to detect concentrations of Salmonella enterica subsp. enterica serovar Pullorum genomic DNA as low as $89fg/{\mu}l$, which is 1,000 times more sensitive than conventional PCR. When artificially contaminated feed samples were analyzed, LAMP-LFD was also more sensitive than PCR. Finally, LAMP-LFD gave no false positives across 350 chicken anal swabs. Therefore, our novel LAMP-LFD assay was highly sensitive, specific, convenient, and fast, making it a valuable tool for the early diagnosis and monitoring of Salmonella infection in chickens.

Silymarin and curcumin have been used for supportive treatment of liver disease of difffrent etiology due to their hepatoprotective activities. The present study was carried out to investigate the hepatoprotective efffcts of silymarin and/or curcuma extract against hepatotoxins induced liver injury. To investigate hepatoprotective effects, the silymarin and/or curcuma extract were pre-treated orally to experimental animals. And thereafter a single dose of hepatotoxin, carbon tetrachloride ($CCl_4$) and acetaminophen were administered through oral or intraperitoneal route, respectively. Chronic liver damage was induced by subcutaneous injection of $CCl_4$ for 3 weeks (2 times/week). Hepatoprotective and therapeutic effects were monitored by estimating serurn ALT and AST levels and by measuring hepatic glutathione (GSH) and malondialdehyde (MDA)levels. Collagen type 1 was detected with irnrnunostaining to assess fibrosis. The results showed that the mix-ture of silymarin and curcuma extract significantly reduced serum biochemistry levels and MDA levels com-pared with those of control group in both acute and chronic animal models. In antifibrotic effect, the relative hepatic collagen content was significantly decreased by silymarin and/or curcuma extract treatment. It was concluded that the complex of silymarin and curcuma extract have a both hepatoprotective and therapeutic effect synergically in rat liver injury induced by heptotoxins.
