Since 1980, burley tobacco plants grown mainly in the western hat of the Korea. have shown two new types of disease symptom. Both symptoms were found to be caused by two different PVY strains : the vein banding type by a PVY strain designated as PVY-VB and necrosis on leaf veins by a PVY strain designated as PVY-VN, Identification of the PVY strains was based on host range test. aphid( Myzus Persicae) transmission test, physical properties, serology, and observation of virus particle morphology. The virus particles were measured to be about 730 nm without any difference in shape or dimensions between the two strains. Both strains also gave a positive reaction to the PVY antiserum in SDS-agar gel double diffusion test. These strains, however, gave a negative reaction to the tobacco etch virus and tobacco vein mottling virus antisera.

Our study was carried out to develop the severity-adjustment model for length of stay in hospital for percutaneous coronary interventions so that we would analysis the factors on the variation in length of stay(LOS). The subjects were 1,011 percutaneous coronary interventions inpatients of the Korean National Hospital Discharge In-depth Injury Survey 2004-2006 data. The data were analyzed using t-test and ANOVA and the severity-adjustment model was developed using data mining technique. After yielding the standardized value of the difference between crude and expected length of stay, we analysed the variation of length of stay for percutaneous coronary interventions. There was variation of LOS in regional differences, size of sickbed and insurance type. The variation of length of stay controlling the case mix or severity of illness can be explained the factors of provider. This supply factors in LOS variations should be more studied for individual practice style or patient management practices and healthcare resources or environment. We expect that the severity-adjustment model using administrative databases should be more adapted in other diseases in practical.

In our previous studies, we reported that Selaginella Tamariscina(ST) induced apoptotic cell death in HL-60 cells selectively. The cell viability after treatment with extract of ST was quantified by MTT assay and trypan bleu exclusion method. The results showed that application with ST in HL-60 induced 40% cell death at the concentration of 400 ㎍/ml. The cancericidic effect of Selaginella Tamariscina was mediated by apoptosis. Thus, HL-60 cells exposed to Selaginella Tamariscina displayed the DNA fragmentation ladder and nucleus chromatin condensation characteristic for apoptosis. The enzyme activity of caspase-3 and actived caspase-3 protein were markedly increased in HL-60 cells treated with the extract of Selaginella Tamariscina. In addition, the extract of Selaginella Tamariscina induced cleavage of PARP, a known substrate for caspase-3. The expression of Bcl-2, anti-apoptotic protein, was decreased by treatment of the aqueous extract of Selaginella Tamariscina in a dose-dependent manner. And the expression of pro-apoptotic Bax protein was increased. In conclusion, our results suggest that the extract of Selaginella Tamariscina may induce the apoptotic death of HL-60 cells via activation of caspase-3, cleavage of PARP protein, depletion of cellular ATP levels and Bcl-2 degradation.

This study examined the knowledge and understanding of integrative medicine in Korea, specifically conflicts between western and oriental medicine within Parallel (Dual) health care systems. Qualitative methodology using grounded theory guided semi-structured, in-depth interviews with Western Medical Doctors (W.M.D., n = 6), Oriental Medical Doctors (O.M.D., n = 5) and Traditional Chinese Medicine Practitioners (T.C.M.P., n = 4). Thematic analysis was used to determine broad themes from the interviews. 15 professionals (W.M.D. (40%), O.M.D. (33%), T.C.M.P. (27%), 10 males (67%) and 5 females (33%), mean age 45) were interviewed, recorded, and transcribed. Thematic analysis revealed three key themes: systematic conflicts, integration and future directions. Subthemes of systematic conflicts included: credibility of Oriental Medicine, commercial imperatives, maintaining social standing of O.M.D., professional qualifications and lack structures supporting collaborative practice. Integration subthemes included lack of academic linkage and clarity for appropriate triage, opposing medical paradigms and limited social imperative. Future directions should include: social justification, guarantee of oriental medicine legitimacy, role of government and understanding of scientific evidence. To successfully integrate dual medical systems there is a need to address differences in social-environmental factors and perceptions of scientific understanding, as well as developing strong academic links in clinical practice.

With the fast increment of fusion ICT(Information and Communication Technology), new creative tourism model is required for the revival of local economy. We come up with new frame that is able to increase tourists and revive local economy through ICT fusion such as spatial informaion, contents, game, smart phone, wearable device and wireless internet. In this paper, we propose 'Gamified Tourtainment Service Platform' that can be provided tourists with user custom tour guidance and gamified tour services for motivation, fun, contest, reward in the environment of outdoor. This platform is a kind of framework for creating and providing gamified creative tour services and a gateway for increasing tourist and reviving commercial local economy. We also propose the real tourtainment service application that is implemented with this platform and smart phone.

This study aims to understand main contents of the National Mental Health Strategy and changes after mental health reform through the National Mental Health Strategy in Australia, and to find some convergence policy implications on mental health policy in South Korea. The direction of reform has changed considerably over the 20 years that the National Mental Health Strategy has been in place including the National Mental Health Policy(1992, 2008), the National Mental Health Plan(1993~2014), COAG National Action Plan on Mental Health(2006~2011), the Roadmap for National Mental Health Reform 2012-2022. The National Mental Health Strategy has advocated fundamental change in the national spending on mental health, mental health service provision, the expansion of community-based mental health services and care system, NGO, consumer and carer participation in mental health care.

Carcinoma of the prostate is a common malignancy affecting elderly men. Lung metastasis from prostate cancer occurs frequently, but tumor metastasis to the central bronchi that clinically mimics primary bronchogenic carcinoma are very rare. We report a 73-year old man with endobronchial metastasis from prostatic carcinoma presented with respiratory symptom cough. Diagnosis of tissues taken from materials which were used for bronchoscopic biopsy and prostate biopsy and immunohistochemical staining for prostate specific antigen (PSA) confirmed a case of endobronchial metastasis from prostatic carcinoma. Hormonal therapy (LHRH agonist) was applied to this patient.

The maximum accuracy of position control by using an industrial robot is about $100{\mu}m$, whereas the maximum tolerated imprecision in the position of precision parts is about several tens of micrometers. Therefore, it is very difficult to assemble parts by position control only. Moreover, in the case of precision assembly, jamming or wedging can easily occur because of small position/orientation errors, which may damage the parts to be assembled. To overcome these problems, we investigated a force control scheme that provides proper motion in response to the contact force. In this study, we constructed a force control system that can be easily implemented in a position-controlled manipulator. Impedance control by using an admittance filter was adopted to perform stable contact tasks. It is shown that the precision parts can be assembled well by adopting impedance control and blind search methods.

본 연구는 수술에 사용하는 생리식염수가 수술의 종류와 수술진행단계에 따른 오염수준을 파악하여 생리식염수의 적절한 교환시점과 교환방법을 제시하기 위하여 시도되었다. 1500 병상 규모의 대학병원에서 1명의 일반외과 의사가 집도한 37건의 수술을 대상으로 하였다. 37개의 수술 각각에서 피부 절개전, 장기절제 후, 그리고 피부 봉합시의 3 시점에서 수술에 사용된 생리식염수와 공기에 노출시킨 생리식염수에서 각각 50 mL의 생리식염수를 채취하여 얻은 균주의 수를 비교하였다. 공기에 노출시킨 생리식염수에 비해 수술에 사용된 생리식염수에서 균주가 보다 많이 검출된 것으로 나타났다. 특히 수술의 종류에 관계없이 수술 마지막 단계 즉 피부봉합 단계에서 수술에 사용된 생리식염수의 오염수준이 급격히 증가한 반면 공기에 노출시킨 생리식염수의 오염수준 변화는 미미했다. 수술에 사용한 생리식염수에서는 Enterococcus(9.5%), Enterobacter species(4.6%), E. col i(2.8%), Alcaligenes species(1.2%), Klebsiella species(0.9%) and Pasteurella multocida(0.8%) 등의 균주가 검출되었으나 공기에 노출시킨 생리식염수에서는 이러한 균종이 검출되지 않았다. 수술실의 공기가 수술에 사용하는 생리식염수의 오염요인으로 작용하기보다는 수술조직이 생리식염수의 오염요인으로 작용하는 것으로 사료된다. 특히 수술에 사용하는 생리식염수의 오염가능성을 최소화시키기 위해 수술소요 시간이 길어지거나 또는 오염 수술의 경우 절제부위가 봉합된 후에 수술에 사용하는 생리식염수, 생리식염수를 담는 용기 및 봉합에 이용되는 봉합감자 등을 새로이 준비하여 피부 봉합에 이용해야 할 것으로 사료된다.
