Purpose: Transverse type or volar oblique type of defect of thumb tip can be covered by Moberg flap or second toe pulp free flap. We compared these two methods in functional result, patients' satisfaction, and sensation, etc. to find a better way to cover the defect of the thumb tip. Methods: From 2003 to 2006, we chose the patients randomly with preoperative pictures. The patients had the defect of the thumb tip which is either transverse or volar oblique type. The 6 patients were treated with Moberg flap and other 6 patients were treated with second toe pulp free flap. We have analyzed the results by 2 point discrimination, side pinching power test, pulp to pulp pinching power test, pain scales (visual analogue scale), satisfaction scales of the patients (functional and aesthetic), the degree of the range of motion, etc. Results: All flaps survived without any complications. In the cases of Moberg flaps, the value of static 2 point discrimination test was 5.6 mm, and the value of moving 2 point discrimination test was 4.8 mm. In the cases of second toe pulp free flaps, the values were 9.6 mm and 9.3 mm. In the cases of Moberg flaps, the value of the Side pinch power test was 6.6 kg, 4.4 kg. In the case of second toe pulp free flaps, the values were 4.8 kg and 2.5 kg. The value of aesthetic satisfaction scale of the patients in Moberg flaps was 5.6, the value of functional satisfaction scale of the patients was 3.6. In cases of second toe pulp free flaps, the values were 5.6 and 3.6. The active range of motion of Interphalangeal joint in the cases of Moberg flaps was 46.6 degree, and the active range of motion of metacarpophalangeal joint was 55 degree, in the cases of second toe pulp free flaps, the values were 36.6 degree and 59 degree. Conclusion: As a result, when the defect of the thumb tip is transverse or volar oblique type, we suggest that the operators choose Moberg flap to cover the defect of the thumb tip.

Purpose: The aim of current study was to evaluate percentage root coverage (RC%) in isolated Miller class III/RT2 labial gingival recession (GR) associated with malaligned mandibular anteriors, using interdisciplinary periodontal-orthodontic treatment as compared to mucogingival surgery alone. Methods: Thirty-six systemically healthy patients having isolated Miller class III/RT2 GR with respect to malaligned mandibular anteriors, were randomly divided into test group: mucogingival surgery using subepithelial connective tissue graft followed by orthodontic treatment and control group: mucogingival surgery alone. Primary clinical parameters included (RC%), recession depth, keratinized tissue width, mid-labial clinical attachment level, interdental clinical attachment level (iCAL), periodontal phenotype (PP), gingival thickness (GT), root coverage esthetics score (RES) and hypersensitivity. Total duration of follow up was 12 months. Results: Mean RC% was significantly more achieved in test group (66.67%±40.82%) in comparison to control group (39.93%±31.41%) at the end of study (P=0.049). Further, complete root coverage was attained in 5/8 cases of test group versus 1/2 cases of control group after 3/12 months respectively. RES and hypersensitivity, showed statistically significant improvement after complete follow up period in both the groups. An ideal RES score of 10 was achieved in 4/7 cases of test group while in 1/2 cases of control group after 3/12 months respectively. Correlation analysis revealed significant negative correlation between RC% and iCAL. Correlation of RC% with GT and PP was non-significant. Conclusions: Interdisciplinary periodontal-orthodontic approach may be more beneficial in terms of achieving improved RC%, esthetic and resolution of hypersensitivity in the management of Miller class III/RT2 GR in malaligned mandibular anteriors.

SOA (Service Oriented Architecture)를 기반으로 하는 소프트웨어는 비즈니스 요구사항에 기민하게 대응할 수 있어 사용이 확대되고 있다. SOA는 느슨한 서비스 결합과 메시지 교환 중심 아키텍처라는 특징 때문에 기존의 테스팅 방법 적용이 제한된다. 본 논문에서는 BPMN (Business Process Model and Notation)을 이용해 테스트 케이스를 생성하는 기법을 제안한다. 먼저 프로세스를 모델링하고, 이를 통해 비즈니스 흐름 그래프(BFG)를 생성한다. BFG의 입출력 차수를 대칭하고, 오일러 경로를 탐색하여 테스트 케이스를 생성한다. BPMN을 이용한 테스트 케이스 생성 기법은 SOA 기반 시스템에 적용 가능하며, 테스트 케이스 수를 감소시킬 수 있다.

The incidence of tuberculosis (TB) in the Republic of Korea remains high when compared to the incidence in other Organization for Economic Cooperation and Development (OECD) countries. The prompt diagnosis and effective treatment of latent TB infection (LTBI) are very important in terms of controlling the burden of TB. The tuberculin skin test (TST) has long been the "gold standard" assay for the diagnosis of LTBI. However, it can show false positive results due to Bacille Calmette-$Gu{\acute{e}}rin$ (BCG) vaccination and infection with many environmental nontuberculous mycobacteria (NTM). The interferon gamma release assay (IGRA) using Mycobacterium tuberculosis (MTB)-specific antigens, was developed for the detection of LTBI. The QuantiFERON-TB Gold In-Tube assay is one of the most commonly used forms of the IGRA. In order to compare the diagnostic efficacy of the TST and IGRA in relation to LTBI among BCG-vaccinated healthy donors, whole blood samples were collected from 51 participants, and the results of the TST and IGRA were compared. Of the 51 cases, 18 cases (35.3%) were positive and 33 cases (64.7%) were negative when using the TST, while four cases (7.8%) were positive and 47 cases (92.2%) negative when using the IGRA. There was no correlation between the size of the induration in the TST and the $IFN-{\gamma}$ protein level. In conclusion, the TST showed higher cross-reactivity among the BCG-vaccinated healthy participants, therefore, the IGRA might be the most suitable assay for the rapid screening of LTBI in BCG-vaccinated healthy population, or for TB contact investigation.

기존의 다양한 테스트 케이스 생성에 대한 연구는 모델로부터 테스트 케이스를 추출한다. 하지만 실무의 경우 자연어 요구사항 문장으로부터 테스트 케이스를 생성할 수 있어야 한다. 이를 위해 자연어 문장의 분석하고, 분석 과정 및 결과를 요구공학 영역에 접목하는 연구는 매우 필요하다. 하지만 한국어 문장의 다양성 때문에, 한국어 자연어 요구사항 분석은 어려운 이슈이다. 우리는 한국어 자연어 요구사항으로부터 테스트 케이스 생성 연구 중 하나로써, 자연어 요구사항의 정의 분석, C3Tree 모델의 생성, 원인-결과 그래프의 생성, 결정 테이블의 생성 단계를 통한 테스트 케이스 생성 방법을 연구한다. 본 논문은 중단 단계로써, 메타모델링 변환 기법을 이용하여 C3Tree 모델 기반의 결정 테이블로부터 테스트 케이스 생성 방법을 제안한다. 이 방법은 모델 변환 규칙의 수정을 통해 모델 to 모델, 모델 to 텍스트로의 변환 과정을 제어한다. 모델이 변형되거나, 새로운 모델이 추가되더라도 프로그램 알고리즘의 직접적인 수정 없이 모델 변환 규칙을 유지보수 할 수 있다. 평가 결과, 결정 테이블에 대한 모든 조합이 테스트 케이스로 자동 생성되었다.

Objectives: To investigate the prevalence of different primary reasons for endodontic referrals and the clinical symptoms of the referred cases. Materials and Methods: Clinical data of total endodontic treatment cases (1,014 teeth) including endodontic referral cases (224 teeth) between January 1, 2010 and December 31, 2012, at Kangdong Sacred Heart Hospital, were investigated retrospectively. The one major reason for referral, the clinical symptoms, and the resulting treatment procedures of referral cases were recorded. The percentages of clinical symptoms of the endodontic referral cases and the total endodontic treatment cases were compared by ${\chi}^2$ test for each symptom. Results: Persistent pain was the most frequent reason for endodontic referral (29.5%), followed by presence of gingival swelling and sinus tract (24.1%), and apical radiolucency (12.9%). Referrals in cases involving endodontic difficulties such as canal calcification, broken instruments, post, perforation, and resorption were less than 5.0%, respectively. The percentages of four major clinical symptoms of pain, apical radiolucency, previous endodontic treatment, and gingival swelling and sinus tract were significantly higher in the endodontic referral cases than those in the total endodontic cases (p = 0.001). Among the included referral cases, 72.8% were treated with nonsurgical endodontic treatment only. Teeth other than the referred teeth were diagnosed as the origin of the problem in 5.8% of the referrals. Conclusions: The high prevalence of pain, apical radiolucency, previous treatment, and gingival swelling and sinus tract in endodontic referral cases suggest that these symptoms may be what general practitioners consider to be difficult and refer to endodontists.

Purpose: We try to evaluate the functional outcomes of the ankle with isokinetic plantaflexion torque for acute achilles tendon rupture cases those treated by primary repair with the Krackow suture technique and early rehabilization. Materials and Method: The authors studied retrospectively, 15 patients of acute achilles tendon rupture treated and followed over six months, from July 1997 to May 2001. There were 12 men and 3 women, and mean age was 39.6year. The repair method of ruptured tendon was single or double Krackow suture technique. One week(5days-2weeks) after operation, early ROM with ankle-foot orthosis was started. We used Arner-Lindholm Scale for the clinical evaluation and analyzed patient's satisfaction and subjective strength deficit. We analyzed the dorsiflexion peak torque and plantarflexion peak torque of the ankle statistically with strength test with Cybex dynamometer. Result: In clinical results, we had 11 excellent cases(73%) and 3 good cases(20%). In patients satisfaction degree, 11 excellent cases(66.6%), 3 good cases(20%) and 2 fair cases(13.4%). And in strength deficit, 3 none deficit (20%), 9 minimal deficit(60%). We evaluated the isokinetic plantar flexion torque in 3months or 6months after operation. After 3 months, isokinetic test showed the mean functional deficits, 32% and 25% at $30^{\circ}$ and $120^{\circ}/sec$, in 7 cases(46.6%) of 15 cases respectively. After 6 months, the mean deficits were in 21%, 24% at 30. and $120^{\circ}/sec$, respectively. At 3 and 6 months' follow up, absolute value of isokinetic test showed increase of 25. 31bs to 421bs and 19.61bs to 271bs at $30^{\circ}$ and $120^{\circ}/sec$, respectively. Conclusion: We had good result for acute achilles tendon rupture treated by Krakow suture technique and early range of motion exercise of the ankle. After 6 months, strength deficit was 21% in all of cases but were able to return pre-injured state. This study shows Krakow suture technique was recommended method for primary repair and early rehabilization of achilles tendon ruptue.
