The purpose of this research is to obtain and analyze dynamic responses from human volunteers for the development of the human-like mechanical or mathematical model for Korean males in automotive rear collisions. This paper focused on the introduction to a low-speed rear impact sled test involving Korean male subjects, and the accumulation of the motion of head and neck. A total of 50 dynamic rear impact sled tests were performed with 50 human volunteers, who are 30-50 year-old males. Each subject can be involved in only one case to prevent any injury in which he was exposed to the impulse that was equivalent to a low-speed rear-end collision of cars at 5-8 km/h for change of velocity, so called, ${\Delta}V$. All subjects were examined by an orthopedist to qualify for the test through the medical check-up of their necks and low backs prior to the test. The impact device is the pendulum type, tuned to simulate the crash pulse of a real vehicle. All motions and impulses were captured and measured by motion capture systems and pressure sensors on the seat. Dynamic responses of head and T1 were analyzed in two cases(5 km/h, 8 km/h) to compare with the results in the previous studies. After the experiments, human subjects were examined to check up any change in the post medical analysis. As a result, there was no change in MRI and no injury reported. Six subjects experienced a minor stiffness on their back for no more than 2 days and got back to normal without any medical treatment.

Periodontal surgery can be directed to remove the irritants from the tooth surface and reduce the periodontal pocket. The purpose of this study is to compare the clinical effects after between modified Widman flap and modified flap in periodontal patients. Ninety six molar area teeth of 9 patients were used. One of sextants performed a modified Widman flap, while the other side performed a modified flap. After initial periodontal therapy, the following measurements prior to surgery(baseline) were taken : pocket depth, gingival recession, clinical attachment level, tooth mobility, bleeding on probing. Also these measurements were taken at 4 weeks, 8weeks, and 12 weeks after surgery. Significant decrease of pocket depth was shown in both techniques, and the degree of decrease was significant in modified flap than modified Widman flap at 12 weeks. Significant increase of gingival recession was shown in both techniques, and the degree of increase was significant in modified Widman flap than modified flap at 4 weeks, 8 weeks, and 12 weeks. Significant attachment gain was shown in both techniques, and the degree of increase was significant in modified flap than modified Widman flap at 4 weeks, 8 weeks, and 12 weeks. Significant increase of tooth mobility was shown in both techniques at 4 weeks, but the decrease of tooth mobility was shown at 12 weeks. Greater decrease of bleeding on probing was shown in both techniques at 4 weeks. Modified flap was better than modified Widman flap in the decrease of gingival recession and the attachment gain. These results indicate that modified flap operation is better than modified Widman flap operation in the effect of periodontal treatment.

고려말~조선전기는 왜구(倭寇)의 침입이 극심한 시기였다. 이를 방어하고자 조선 개국 이후 읍성·산성·봉수 등을 축성(築城)하였다. 이러한 방어체계를 갖추면서 어떠한 방법으로 방어 했는지를 하동지역으로 한정하여 왜구의 침입루트 및 방어체계에 대하여 고찰해보았다. 먼저 침입루트를 해안-섬진강 루트와 해안-육지 루트로 나눈 뒤, 침입 루트상에 설치된 방어시설인 읍성·산성·봉수대의 현황에 대해 살펴보았다. 문헌검토를 통해 하동지역은 다른지역에 비해 왜구의 침입 횟수가 적었고, 규모도 작았을 것으로 추정하였으며 침구(侵寇)시기는 겨울과 봄에 집중되었음을 알 수 있었다. 이러한 침입 루트와 방어시설을 살펴본 결과 지형 및 주변 유적을 통해 왜구 침입시 4단계의 방어선을 설정해 보았다. 하동지역 방어선 설정과정에서 하동지역의 방어상 몇 가지 특징을 살필 수 있었다. 첫째, 방어시설의 배치관계이다. 하동읍성을 중심으로 5km 내에 대부분의 방어시설이 존재한다는 것이다. 둘째, 하동읍성의 견고성을 뽑을 수 있다. 셋째, 산성의 규모를 보아 둘레가 1000m를 넘지 않는다. 이는 왜구가 침입시 소규모로 침입한 경우를 대비해 쌓았을 것으로 판단된다. 넷째, 산성과 봉수와의 배치관계를 보면, 봉수대는 대부분 산성 내에 위치하거나 산성 주변에 위치하는 것을 알 수 있다. 다섯째, 봉수대 배치 구도의 중요성이다. 각 방어선 마다 배치된 봉수대가 삼각형 구도를 갖추어 남해안으로 출몰하는 왜구를 효과적으로 감시할 수 있었음을 알 수 있다. The late Koryo through the early Chosun Dynasty was the period during which Japanese invasion was at peak. To defense the Japanese pirates, town walls, mountain fortress walls and beacons has been built since the foundation of Chosun Dynasty. This study attempted to know how ho these defense systems were used against the Japanese attack, the invasion routes of Japanese pirate and the defense system of the Dynasty, focusing on Hadong area. First of all, this study segmented the invasion routes into the seashore to Sumjin River and the seashore to the shore and then examined the current status of the defense systems (town walls, mountain fortress walls and beacons) built in each route. Through the investigation, this research could reach the assumption that Hadong area was less offended by the Japanese pirate than any other areas and the scale of the Japanese attack was not significant. In addition, it was thought that the periods of the attack were concentrated in winter and spring. As the result of looking into the invasion routes and the defense system through the related topographies and confirmed remains, we could picture the defense lines against the attack. Some characteristics of the defense system in Hadong area were found in the process of setting the lines. First, the arrangements of the defense system are located within 5 km from Hadong town walls. Second, the town walls are firm. Third, judging from the shape of the mountain fortress walls, they are shorter than 1000 meter in circumference. This short circumference allows thinking that they were built against small scale of offense. Fourth, the arrangement of the mountain fortress and beacons guides us to picture that most of beacons were positioned inside the fortress or around it. Fifth, the spatial composition of the beaconshas importance. The beacons, which were built on each defense line, were planned in a triangular composition. It was the effective lineup in defending the Japanese pirate landing on the southern coast.

The purpose of this study is to clinically evaluate and report the effectiveness of radiofrequency microdebrider (Topaz, ArthroCare) treatment in lateral epicondylitis patients. From March to July 2003, 15 patients of 17 elbows were prospectively followed. Candidate for the treatment were lateral epicondylitis patients who had symptom more than 6 month and failed to respond to conservative treatment, including medication (non-steroidal anti-inflammatory drugs), external gel or patch, and steroid injections. All patient who scored greater than grade 3 (fair) on the Self-administered Roles and Maudsley Pain (SRMP) score were selected for the procedure. All procedure was done using local anesthesia and ArthroCare microdebrider by a single surgeon. Postoperative assessments were done on postoperative period 12 month of two previous subjective scores and a simple functional assessment asking better, same, or worst function after the procedure. Mean age of the patients was 45 years old. Mean symptom duration before the procedure was 22.6 months. After the procedure, the mean Pain Visual Analogue Scale improved from 7.3 (range, 5-9; standard deviation [SD], 1.2) preoperatively to 3.7 (range, 0-7; SD, 2.1) postoperatively (p< 0.001). After the procedure, five elbows showed no rating improvement, in seven elbows 1 level improvement, in four elbows 2 level improvement, and in one elbow 3 level improvement. Overall, 71% (12/17) showed improvement after the procedure according to the SRMP score rating. Although 29% (5/17) of the elbow showed no improvement on SRMP score, among them five elbows were still rated decrease in Pain Visual Analogue Scale.

홍성우(Hong Sung Woo),장우진(Jang Woo Jin) 한국지적정보학회 2011 한국지적정보학회지 Vol.13 No.1

최근 도시재생은 지역이라는 한정된 공간에서 경제, 사회, 환경, 문화 분야 등을 포괄하는 종합적인 관점에서 접근되고 있으며, 커뮤니티 비즈니스 형태의 사회적기업에 의해 지역 취약계층에 대한 일자리 제공과 복지서비스 등을 제공하는 도시재생 전략을 활용하기도 한다. 이런 관점에서 우리 정부는 각 부처에서 다양한 형태로 진행되고 있는 도시재생 관련 사업을 유기적이고 종합적인 관점에서 추진하고자 물리, 경제, 사회, 문화, 환경적 측면에서 지속적으로 추진 가능한 연계대상사업을 선정하였다. 또한 2007년 이래 법제도의 정비에 기반해 사회적기업이 발굴ㆍ육성되어 양적인 성장을 보이고는 있으나 궁극적으로 사회적기업의 지속가능성에 대한 의문이 다각적 측면에서 제기되고 있다. 이런 시점에서 본 연구는 사회적기업의 지속가능성을 기존의 도시재생(연계사업) 영역의 중요도 분석을 통해 탐색해 보고자 한다. 이를 위해 먼저 지속가능성의 개념적 유형화, 그리고 도시재생사업과 사회적기업과의 연계성에 관해 이론적인 측면에서 논의한다. 이를 바탕으로 도시재생연계사업 영역의 중요성에 대한 전문가 인식을 설문조사하여 사회적기업의 분야별 지속가능성 확보를 위한 분야별 도시재생연계사업과의 연계 가능성을 실증적으로 분석해 보았다. AHP 계층구조에 근거하여 분석한 평가영역 간 중요도는 문화재생(.330), 경제재생(.271), 환경재생(.235), 복지재생(.164) 등의 순서로 중요도가 분석되었는바 이러한 결과는 문화를 기반으로 하는 도시재생 전략의 접근법이 우리나라에서도 중요하게 인식되고 있으며, 사회적기업의 지속성 및 도시재생의 성공적 수행을 위한 지역차원의 전략적 계획수립에 있어서 지역의 문화자원을 활용한 사업발굴과 유형화가 구체화되어야 할 것이다. In recent, urban renaissance has been approached in the comprehensive perspective including economic, social, environmental and cultural aspect in a certain area. Social enterprise such as community business which offers job opportunities and social services to the underprivileged such as the disabled and longtime job seekers is utilized as a strategy of urban renaissance in the developed countries. In this sense, this study aims to explore the possibility of connection between the urban renaissance program and social enterprise in order to enhance the sustainability of social enterprise in terms of economic, environmental, cultural and social aspect empirically. For this purpose, the AHP analysis framework is constructed with 2 tiers(sustainability and urban renaissance) and four parts(economy, environment, culture, and welfare) and the expert survey is conducted. The result of AHP analysis shows that the relative importance(significance) of cultural aspect is highest among four aspects and the importance of economic aspect followed. Also, the relative importance of supporting program of sports facilities to the community in the cultural aspect is highest in the 16 urban renaissance programs. The emphasis on the strategy of urban renaissance based on regional culture would be reflected in this AHP analysis result.
