Recently various service is provided as developing of wireless internet in mobile environment. Also mobile GIS service is provided too. In mobile environment, the service use wireless internet. So it is not adaptable to apply the service which provided in existing internet environment. And owing to each service provide service independently, mobile GIS service is hard to look for interoperability This paper is developed encoding standard for mobile GIS application for service to be conform mobile environment and to be guarantee interoperability between service. First, we analyzed GML 3.1 standard for encoding standard and investigate encoding method to use in mobile GIS service. And we derive characteristic of GIS in mobile environment to analyze domestic GIS. We develop mobile GIS encoding standard by analyzing MATRIX of analyzed GML 3.1 standard and derived characteristic to analyze service.

연구목적: 정신장애의 정확한 진단과 평가는 임상에서뿐만 아니라 신뢰성 있는 연구를 위해서도 매우 중요하다. Structured Clinical Interview for DSM-IV(SCID)는 임상전문가들이 사용하는 진단도구로서, 비교적 짧은 시간에 정확한 진단을 내릴 수 있다. 본 연구는 한국어판SCID를 개발하고 그 신뢰도를 평가하기 위해 수행되었다. 방법: 국문학자가 포함된 번역위원회를 통하여 연구용판 SCID를 번역한 후, 정신과 의사 2인과 임상심리학자 1인에게 한국어판SCID 실시방법을 교육시킨 뒤 한국어판SCID를 이용한 면담의 평가자간 신뢰도 (interrater reliability)를 검증하였다. 면담 대상은 1999년 2월에서 3월까지 2개 병원 정신과에 치료중인 환자 90명(남:41명, 여:29명)이었다. 결과: 현재 장애(current disorder) 평가에서 주요 우울장애, 기분부전장애, 정신분열병, 알코올 남용 및 의존, 기타 물질 남용 또는 의존, 여러 불안장애들 및 섭식장애 등과 같은 대부분 장애의 kappa값은 .70이상으로 매우 높았다. 그 이외의 양극성 장애, 망상장애, 광장공포증, 감별 불능 신체화 장애 및 건강염려증의 kappa값도 .69에서 .40사이로 수용할 수 있는 정도였다. 평생 장애(lifetime disorder)에서는 양극성 장애(k=.69)와 감별 불능 신체화장애(k=.59)를 제외한 다른 모든 장애의 kappa값이 .70이상이었다. K-SCID 면담시 Ⅰ축 질환에 대하여 흔하게 다중 진단이 내려졌으며, 평균 진단 수는 1.5∼1.7개로 나타났다. 결론: 한국어판 SCID는 신뢰도가 높은 진단도구로 생각되며, 향후 정신질환의 정확한 진단과 임상연구에 유용하게 사용될 수 있다. Objectives: Accurate diagnosis and assessment for psychiatric disorders is crucial for research, as well as for clinical practice. Structured Clinical Interview for DSM-Ⅳ(SCID-RV) is a less time-consumimg and more accurate structured diagnostic interview form. It can be used by clinical professions and is known for a reliable diagnostic tool. Present study was conducted to develop Korean version of SCID-RV and to test the inter-rater reliability. Methods: The authors have translated original SCID-RV into Korean, and revised in parallel with sociocultural background of Korea. Ninety patients from two psychiatric hospitals, both outpatient and inpatient, were interviewed and rated independently by three raters. Results: The kappa coefficients for most of illnesses, such as major depressive disorder, dysthymia, schizophrenia, alcohol abuse and dependency, anxiety disorder and eating disorder were excellent(>0.70) in the evaluation of current disorders. And the kappa coefficients for bipolar disorder, delusional disorder, agoraphobia, undifferentiated somatoform disorder, and hypochondriasis were acceptable(>0.40) in the evaluation of current disorders. In the evalua-tion of lifetime disorders, the concordant rates of all the diagnoses except bipolar disorder and undifferentiated somatoform disorder were excellent. Lack of hierarchy in DSM-Ⅳ allows for multiple Axis I diagnoses. Mean numbers of Axis I diagnoses per subject assigned by the three raters were 1.5-1.7. Conclusions: Our findings confirm that SCID-RV yields highly reliable diagnoses. SCID-RV is recommended for accurate diagnosis in clinical practice and research on psychiatric disorders.

송익준(Ik-Joon Song),신경진(Kyung-Jin Shin),김정우(Jungwoo Kim),박익규(Ik Kyu Park),이승준(Seung-Jun Lee) 한국생산제조학회 2015 한국생산제조학회지 Vol.24 No.6
The objective of this study is to validate the performance of the current k-ϵ turbulence model for a single-phase turbulent natural convection, which has been considered an important phenomenon in nuclear safety. As a result, the natural convection problems in the 2D and 3D cavities previously studied are calculated by using the ANSYS Fluent software. The present results show that the current k-ϵ turbulent model accounting for the buoyancy effect is in good agreement with the previous results for the natural convection problems in the 2D and 3D cavities although some improvements should be required to get better prediction.

Background: The purpose of this study was to evaluate the recurrence of hepatocellular carcinoma and the survival rate of patients who received radiofrequency ablation (RFA) after transarterial chemoembolization (TACE) with that of patients treated with TACE or RFA alone. Methods: Two-hundred and one patients with HCC were consecutively enrolled at Seoul St. Mary`s hospital between Dec, 2004 and Feb, 2010. Inclusion criteria were a single HCC≤5.0 cm or up to three HCCs≤3.0 cm, with no vascular invasion or extrahepatic metastasis. In all, HCC patients (n=87) who had undergone RFA after TACE and those who received TACE (n=71) or RFA only (n=43) were analyzed. Propensity scores were generated to select from each arm of the study. Results: Median follow-up periods were 33.3 months (6.8-80.9 months). The recurrence rates at 1, 3, and 5 years in the TACE+RFA and RFA groups were similar (6, 33, and 54%; and 10, 31, and 48% respectively); however, those in the TACE group were higher (17, 58, and 78%, respectively). In the TACE+RFA group, the local recurrence rates were significantly lower compared with the RFA group (P=0.034). The overall survival rates at 1, 3, and 5 years in the TACE+RFA group (98, 95, and 90%, respectively) were superior to those in the TACE or RFA groups (98, 90, and 83%; 94, 84, and 71%; P=0.064, 0.011, respectively). In a multivariate analysis of overall survival using a Cox regression model, combination treatment was a significant independent factor for survival compared to RFA and TACE monotherapy (HR, 0.371; 95% CI, 0.141-0.973; P=0.0371, HR, 0.476; 95% CI, 0.230-0.986; P=0.046, respectively) Conclusion: The combination of TACE and RFA is an effective treatment for early-stage HCC and results in lower local recurrence and better overall survival rates than those achieved by RFA or TACE alone.

목적: 국외 연구에서 염증성 장질환 환자에서 H. pylori 감염률은 일반인보다 낮다고 한다. 이에 국내 염증성 장질환 환자들에서 H. pylori 감염률을 알아보고, IBD 치료약제나 표현형과 관계가 있는지 조사하였다. 대상 및 방법: 2004년 11월부터 2006년 4월까지 국내 6개 의료기관의 외래를 방문한 169명의 궤양성대장염 환자와 147명의 크론병 환자들을 대상으로 전향 연구를 시행하였다. 염증성 장질환 환자들과 같은 날 상부위장관 및 대장내시경을 포함한 건강검진을 받은 수진자(염증성 장질환이 없는 것으로 확인된) 중 성별과 나이가 일치한 316명을 대조군으로 선정하였다. 결과: 염증성장질환 환자의 H. pylori 감염률은 25.3% (궤양성대장염 32.0%, 크론병 17.7%)로 대조군(52.5%)에 비해 통계적으로 유의하게 낮았다. 염증성 장질환 환자 중 특히 60세 미만, metronidazole이나 ciprofloxacin을 복용한 경우 H. pylori 감염률이 낮았지만, 항생제 복용력이 없는 경우에도 대조군에 비해 H. pylori 감염률이 낮았다. 크론병의 표현형에 따른 H. pylori 감염률의 차이는 없었다. 결론: 국내 염증성 장질환 환자들은 대조군에 비해 H. pylori 감염률이 낮았고 이러한 현상은 특히 60세 미만에서 두드러졌다. Background/Aims: The prevalence of Helicobacter pylori (H. pylori) infection has been reported to be lower in individuals with inflammatory bowel disease (IBD) in some Western countries. We investigated H. pylori infection in Korean patients with IBD and any possible associations of H. pylori infection with drug therapy for IBD and the phenotype of Crohn`s disease (CD). Methods: We studied 316 unselected patients with IBD, including 169 ulcerative colitis (UC) patients and 147 with CD, and the control group consisted of 316 age- and gender-matched healthy people who received a comprehensive medical examination for a regular checkup purpose. Infection rates of H. pylori as detected by the urea breath test were compared between the IBD patients and the controls. Results: A statistically significant difference in H. pylori infection rate was noticed between the IBD patients (25.3%) and the controls (52.5%; p<0.001), and between UC (32.0%) and CD patients (17.7%; p=0.04). Among the IBD patients, the age group of <60 and individuals with a history of taking metronidazole (13.0%; p=0.038) or ciprofloxacin (6.7%; p=0.001) were found to have a meaningfully lower infection rate, but those who did not take antibiotics still showed H. pylori infection rate significantly lower than the controls (CD 22.0% vs. UC 33.8% vs. Control 52.5%, p<0.001). With an exception of age, phenotypic characteristics showed no significant relations with H. pylori infection rate in CD patients. Conclusions: Korean patients with IBD, particularly CD, were found to have a significantly lower H. pylori infection rate than the controls. This association was more evident in those <60 years old, which suggested that H. pylori infection might be deemed to lower possible risks of IBD in younger adults.

Although the treatment of gallbladder stones is mainly dependent on surgical intervention, recently medical treatment such as oral bill acid therapy, dissolution therapy with MTBE or extracorpareal shock wave lithotripy have been also performd. For the auccess, of these medical therapy. the composition of gallbaddser stones is a important factor. So, to predict the comical composition, we examined 100 cases of the surgically removed gallblraldder stoned by ultrasonaraphy. And we compared the ultrasonograplic findings of gallbladder stones with the chemical compotions and the features of cut surface. Alan we compared the presence of the calcification on the simple abdominal X-ray. The chemical components of gallbladder stones were analysed by ultrared spectrometer. Ultrasonographic findings were claesafied into five characeristic types; the shooting-star (SS) type, the crescent (C) type the half-moon (HM) kype, the full-moon (FM) type anal the star-dust (SD) type. The roved as fallows. In chemical compositions of gallstones, 67 cases (67%) were cholesterol stones with 26 eases (2^%) of pure cholesterol stones, and 30 cases (30%) of cholesterol-bilirubinate stones, bilruastnate stone were 25 cases (25%), calcium-carbanate stones were 7 cases (7%), and calcium pltcasphate stone was 1 case (1%). In ultrasonograhic fielding of gallstones, the SS types were 24 cases (24%), the C types 43 cases (43%), the FM types 16 uses (16%), the HM types 14 cases (14%) and the SD types were 3 cases (3%). In the relationship between tcltrasonographic findings and cheat composition, tine SS type itrcluded cholestro stones with 21 cases (88%). The C type included cholesterol stones with 30 cases (70%) and bilirubinate stones with 13 cases (13%). The HM types included chstrol stones with 9 cases (64%), bilruinate stones with 3 gases (24%) and calcium carbonate stones with 2 cases (14%). The FM types inch cholesterol stones with 5 cases (31%), bilirubinate stone with 6 cases (38%), calcium carbons a stones with 4 canes (25%), and calcium phosphate stone with 1 case (6%). The SD types incitude cholesterol stone with 2 cases (67%) and hilirubinatie stone with 1 case (33%). Cholesterol stone were found mainly in the C type (45%) and the SS type (31%). Bilirubinate stones were found mainly in the C type (52%) and the FM type (24%). In comparison between the presence of calcification on the simple abdominal X-ray and the chemical composition with ultrasonographic findings, 9 of 100 cases of gallbladder stones showed calcification on the simple abdominal X-ray with 2 choleBterol stonecs; 5 bilirulalnabe stone, 2 calciim carbonate stones. Non-cholesterol stones showed more frequent calcification finding than eholeacrol stones. In the features of the cut surfaces of the 100 gallbladder stones, the concenteric types were 64 cases (64%), the homogenous types were cases (26%), and to radiating types were 10 cases (10%). And there was no correlation between the features of the cutsurfaces of gallbladder stones and the ultrarsorographic findings. , In conclusion, the classification of ultrasonographic findings are useful to predict, the chemical compositions of gallblardder stones and to decide on the therapeutic method of gallbladder stones.

Cholesterol embolization syndrome (CES) is a multiple systemic disease caused by the embolization of cholesterol crystals from an atherosclerotic plaque of a proximal large-caliber artery, which results in the occlusion of distal small to mediumsized arteries. CES is characterized by development of a multitude of small emboli over time, and should be distinguished from arterial thromboembolism, which occurs through the obstruction of medium-sized to large arteries by one or a few large emboli. We report on a case of CES initially presenting as acute limb ischemia following an intervention for iliac artery occlusion.
