After contracting of Korea-China FTA, we have expected the trade volume has mutually been increasing a lot. If we are using this contract, we would make an activation of Korea economy. Especially, Korea youngman has been caught a big chance to make a business in Korea & China. For example, Xian, which is one of center of silk road, has become big strategy area. As we need to focus on this area, we will be expected to indirect influences of consumer's industries like cosmetic, fishery products, food service, eco-friendly items. Recently, the youngman starting up a business has become a trend of kinds of alternative new job. Then, we have to provide practical solution for young man. One of this solution is 'starting up a business'. In this study, I empirically investigated the relation between Korea-China FTA and the youth starting up a business. So, I believe that this study can light up on the direction of effective starting up for making & success a business in China.

The Zygomatic arch is structurally protruded and is easily fractured. The classic management of zygomatic arch fracture has been mentioned the Keen, Lothrop, Dingman and Ailing and threaded K-wire. All of the above methods have advantages and disadvantages. To minimize the disadvantages, we performed threaded K-wire for the first time using C-arm image intensifier. The subjects were 16 patients with Knight North group II (Zygomatic arch fracture). Among them the C-arm was used in 12 patients and the operator used sensitivity general method in 4 patients and confirmed the operation by mobile X-ray equipment. In conclusion, both groups were satisfied surgically and cosmetically. Using the C-arm, actual image at the time operation was clear and satisfied, the surrounding tissue damage was minimized and at was more accurately completed. The operation time was shortened by 30 to 60 minutes proving it to be an efficient method. We suggest though that further studies be needed to evaluate the radiation effect on these patients.

Purpose: Closed reduction is most common treatment method for nasal bone fracture but it requires secondary correction operation commonly. For preventing secondary revision, we applied ultrasonography during closed reduction of nasal bone fracture and examined the result of operation. Methods: 80 patients were sorted into 2 groups, ultrasound-guided closed reduction group(n=40) and manual closed reduction group(n=40). We classified the unilateral fracture involving lower 1/2 of nasal bone into type I, the bilateral fracture involving lower 1/2 of nasal bone into type III and the fracture of upper 1/2 of nasal bone into type III. The occurrence rate of overcorrection and undercorrection were evaluated by comparing preoperative and postoperative MDCT(Multi Direction Computed Tomography). Results: In manual closed reduction group, overcorrection were found in 4 patients and undercorrection were found in 3 patients. In ultrasound-guided closed reduction group, overcorrection was not observed and undercorrection was observed in 2 patients. Conclusion: Intraoperative ultrasound evaluation of nasal bone fracture resulted in reduced occurrence rate of secondary nasal deformities, showed easier detection of the fractured site and have superiority upon simple physical examination or simple x-ray.

Purpose: The choice of open versus closed reduction for mandibular subcondylar fracture is a debatable issue. To evaluate the advantage of open approach to closed method with IMF(intermaxillary fixation), we conducted a retrospective study to compare the outcomes of each method. Methods: From 2002 to 2006, 29 patients with mandibular subcondylar fractures were treated by open or closed reduction. 17 patients were treated by open reduction and 12 patients by closed reduction and IMF. Each group was assessed for duration of mandibular immobilization, incidences of buccal palsy, malocclusion, TMJ(temporomandibular joint) pain, and deviation of the mandible on mouth opening. Results: All cases showed accurate reduction in anatomical position, no significant displacement and no deviation on mouth opening during the follow-up period. IMF period is statistically shorter in open reduction (p<0.05). Differences in incidence of other complications were not significant statistically. Conclusion: As there are significant independent morbidities associated with IMF which requires postoperative rehabilitation, prolonged temporomandibular immobilization should not be overlooked. Some patients with poor compliances will not tolerate IMF in nonsurgical treatment. In the aspect of patient's convenience and early recovery by short IMF period, open reduction would be recommended as a better treatment method.

본 논문은 기존의 귀납적 결정 트리 방식에서의 문제점 개선을 통한 사용자 관심 프로파일 구축을 목적으로 한다. 특히 사용자 관심 프로파일의 정확도 향상을 위한 속성 선택에 대한 연구에 초점을 맞추고 있다. 사용자의 관심, 비관심 문서를 대상으로 사용자 관심 키워드를 생성하고 이를 바탕으로 초기 문서들을 재표현한다. 재표현된 문서를 입력 집합으로 하여 기계학습을 진행한다. 본 논문의 의사 결정 트리 생성 알고리즘은 입력 집합을 클래스별로 가장 잘 나누는 속성을 선택하여 노드를 구성하는 면에서는 기존의 알고리즘과 같다. 그러나 기존의 의사 결정 트리 알고리즘에서는 hill-climbing.방식을 사용함으로써 사용자의 관심을 나타내는 중요한 단어가 사용자 관심 프로파일에서 숨겨질 경우가 발생한다. 이를 최소화하기 위해 특징 추출을 통해 선택된 속성을 그대로 학습의 입력 데이터로 사용하는 것이 아니라 입력데이터를 가장 잘 나누는 속성과 그 다음 속성을 대상으로 disjunctive 연산을 통해 새로운 속성을 생성하여 이것을 속성 집합에 포함시키고 이를 학습의 입력 데이터로 이용한다. 이와 같이 disjunctive operator를 이용하여 새로운 속성을 의사 결정 트리 형성 시 이용하면 사용자의 중요한 관심을 포함하는 의미 있는(semantic) 사용자 관심 프로파일 구축이 가능해지고, 사용자 관심 프로파일을 기반으로 사용자가 관심 있는 문서를 제공할 수 있는 개인화 서비스를 제공한다.

WTO는 범세계적 글로벌 경쟁상황에서 국가간 무역거래를 제한하고 자원배분을 왜곡하여 결과적으로 세계 후생의 감소를 가져오는 개별 국가들의 관세 및 각종 비관세장벽, 그리고 자원의 효율적 배분을 왜곡하는 각국 정부의 보조금 정책 시정을 위해 창설되었다. 항공기산업에 있어서 보조금 논쟁의 특징은 주로 선-선진국간 분쟁에 국한된다는 점에서 기존의 WTO에서 많은 갈등을 빚고 있는 선-후진국간의 분쟁과는 큰 차이가 있다. 한국이 주도적으로 대규모 개발사업을 추진하면서 정부보조금을 지급할 경우에는 장기적으로 보조금 분쟁에 휘말릴 가능성이 있다. 그러나 미국/유럽간 쌍무협정 체결 내용에서 보듯이 개발보조금 지급 비중이 전체 개발비의 33%이상이 되지 않을 경우는 큰 문제가 없을 것으로 예상되며, 추가적 지원이 필요할 경우에는 직접적 개발비 보다는 관련 지 원인프라 지원을 통해 특정성 문제를 회피할 필요가 있다. 또한 한국은 아직 WTO 민간 항공기 협정 미가입 상태이기 때문에 WTO로부터 당장 규제대상은 아니다. 실제로 WTO 회원 가입 절차는 WTO로부터 요청 후 국내 검토를 거쳐 예비회원가입(2년 소요)-정회원의 절차를 거치게 된다. 또한 보조금 지급에 의한 경쟁자의 산업 피해가 직접적으로 드러날 때까지는 더 많은 시간이 소요되기 때문에 실제로 WTO 제재를 받기까지는 상당한 시간을 확보할 수 있다. 그럼에도 불구하고 WTO 회원이 되면 항공기산업의 육성에 많은 제약이 따르므로 사전적으로 충분한 정부 지원을 통해 조속히 국제경쟁력을 키우는 전략이 필요한 것으로 보인다.

Objective : This study investigated the temperament and character traits associated with suicide attempts in patients with mood disorders. Methods : The temperament and character inventory (TCI) was administered to 150 patients who visited psychiatric clinics seeking treatment for mood symptoms. The patients were divided into three groups as follows : non-suicide ideation, suicide ideation and suicide attempt. We also gathered socio-economic data in order to rule out confounding variables. MANOVA was performed to analyze differences in personal temperament and character scores on the TCI between the three groups. Results : The self-directedness and cooperativeness subscales of the TCI are most influenced by the clinical symptoms rated by Beck Suicide Ideation Scale and Hamilton Depression Rating Scale. In the temperament scale, the suicide attempt group scored higher on the novelty seeking and harm avoidance items than the other two groups. The specific temperaments associated with suicidal behavior in patients with depression are impulsivity (NS2) and anticipatory anxiety or pessimism (HA1). Conclusion : In this study, we found that more risky patients who had previously attempted suicide had a temperament of impulsivity or pessimism. This finding suggests that a more cautious approach is needed to assess mood disorder patients with impulsive or pessimistic temperaments in order to prevent suicide attempts.

Metatarsal head and neck fractures are injuries that often result from a direct blow of a heavy objects to the metatarsal head. The head is often impacted or displaced to the plantar aspect that if not treated may cause malunion which later induces painful plantar calluses. If the fracture fragment is large enough, closed reduction may be successfully performed, but when the fragment is small or closed reduction is unsuccessful, open reduction is needed. We present our reduction and fixation technique for the metatarsal head and neck fractures using antegrade intramedullary Kirschner wire (K-wire) without opening the fracture site or infringing the metatarsophalangeal (MTP) joint which allows immediate motion of the joint and partial weight bearing in a stiff soled shoe.

Between January 1984 and December 1986, sixty nine patients, aged 16 months to 25 years [mean age 10.05*6.40 years], underwent total correction of tetralogy of Fallot in Kyungpook national university hospital. In 66 hospital survivors, 30 patients were followed up for 12 to 48 months [mean 30.10*10.26 months]. These 30 patients were classified in two groups, TAP [transannular patch] and Non-TAP group. There were 9 patients in TAP group, and 21 in Non-TAP group. There were no significant differences between two groups in terms of age at operation, follow up duration, ACC time, and bypass time. All patients were evaluated by two dimensional echocardiography, Doppler echocardiography, standard 12-lead electrocardiography, and plain chest X-ray. Right ventricular systolic pressure, pulmonary arterial systolic pressure, pressure gradient between the right ventricle and the pulmonary artery, presence or absence of pulmonary regurgitation and its grading, fractional shortening of the left ventricle, and Qp/Qs in case of remnant ventricular septal defect were obtained by echocardiographic examination. Cardiothoracic ratio was measured by plain chest film, and ventricular dysrrhythmia was detected by electrocardiogram. Comparing the data between two groups, there was significant difference in incidence of postoperative pulmonary regurgitation [p< 0.05], 100%[9/9] in TAP group and 47.6 %[10/21] in Non-TAP group, but all the regurgitations were not severe. There were no significant differences in other comparisons, despite of higher incidence of cardiomegaly in TAP group [CT ratio: 59.3*5.3% VS 54.7*6, 4 %].
