Whenever the accidents occur in the rail way areas, their prompt recovery is very important. The individual way has been used to resolve these accident by direct visiting the site and reporting to others of the person who cares for these cases. As a result, we are planing to operate the MTS (Multimedia Transmission System) for a timely information's transmission to the related peoples in the central control center by transforming the picture information on the accident-site to the digital information.

The purpose of this study was to evaluate the clinical and microbiological outcomes following the use of 30% minocycline-loaded polycaprolacton film and 2% minocycline-loaded gel that was applied locally into pockets combined with scaling and root planing. 25 human subjects who were non-pregnant, non-lactating, aged 20-50 and diagnosed as moderate to advanced adult periodontitis were enrolled. Subjects were excluded if they had a history of severe acute or chronic systemic disease, if they required antibiotic prophylaxis for dental treatment for any reason, or if they reported a history suggestive of hypersensitivity reactions to minocycline or tetracycline. 4quadrants that had several teeth with a 5-8mm probing pocket depth and radiographic evidence of alveolar bone loss for each patient were selected and divided into test sites and control sites according to the split-mouth design. Scaling and root planing was done for each site at baseline(0week). Test sites received the minocycline gel and strip and control sites had saline irrigation. The patients received both treatments simyltaneously. Subgingival irrigation of sterile saline was applied to the control sites for approximately 30 seconds. Minocycline strip and gel was applied into the periodontal pocket at 1, 2, 3, 4 weeks each after scaling and root planing in the test sites. The clinical and microbiological measurements were made at baseline and at the follow-up visits 6, 10, 14, 20 weeks. The results of this study were as follows; 1. The sulcular bleeding index, probing pocket depth and Periocheck test was significantly reduced and the relative proportions of spirochetes and motile rods were significantly reduced and the proportion of cocci was correspondingly increased, in locally delivered minocycline strip group compared to saline irrigation group. 2. In locally delivered minocycline gel group, The effect was the same with minocycline strip group as compared with saline irrigation therapy. 3. There was no significant differences between minocycline strip group and minocycline gelgroup. In conclusion, minocycline HCl local drug delivery combined with scaling and root planing may provide added improvement of clinical and microbiological responses by inhibiting bacterial recolonization of treated sites. It is suggested that the local administration of minocycline-HCl in the periodontal pocket is effective when combined with subgingival mechanical debridement.

목 적 : 유방암 치료에 있어 피부선량의 측정은 매우 중요하다. 치료계획시에는 처방선량에 비해 초과선량이나 부족선량이 생길 수 있으므로 이에 대한 유방암의 여러 가지 치료계획간 피부선량 평가가 필요하다. 이에 대해 본원에서는 다양한 선량계를 이용하여 선량을 분석하여 유방암치료에 적용하고자 한다. 대상 및 방법 : 유방암은 기본적으로 접선방향 치료계획 시 일어나는 skin dose(Drain site, Scar)의 선량차이를 알아보기 위하여 인체모형팬텀을 이용하였다. 인체모형팬텀을 전산화단층촬영하고 전산화치료계획에서 open과 쐐기필터(Wedge filter)를 이용한 치료계획, Field-in-Field를 이용한 치료계획, 그리고 Dose fluence를 이용한 Irregular compensation 치료계획을 세우고 컴퓨터치료계획 프로그램(Eclipse)으로 선량관심점과 측정점의 선량을 비교하였다. 치료실에서 인체모형팬텀을 위치시키고 선량비교를 위하여 각 치료계획 측정점에 열형광선량계(themoluminesence dosimeter, TLD)와 MOSFET(Metal oxide-silicon field effect transistor)을 이용하여 선량을 측정하여 비교평가 하였다. 결 과 : 피부선량은 치료계획 중심점을 기준으로 위와 아래는 Dose fluence를 이용한 Irregular compensation 치료계획 사용 시 MOSFET을 이용한 선량측정에서 가장 많은 선량이 들어가는 것으로 나타났다. 내측과 외측의 측정선량은 open과 쐐기필터 치료계획에서 TLD와 MOSFET을 이용하여 측정시 5.7%에서 10.3%까지 낮게 나타났다. 반대쪽 유방의 선량은 open 치료계획이 가장 적었고, Dose fluence를 이용한 Irregular compensation 치료계획을 사용 시 가장 많은 선량이 측정되었다. 치료종별 치료계획상에서는 내측과 외측의 선량편차가 가장 컸으며, TLD와 MOSFET 측정시에도 같은 경향을 보였다. 외측은 TLD, 내측은 MOSFET이 가장 편차가 컸다. 결 론 : 치료계획에 따른 피부선량은 전반적으로 Dose fluence를 이용한 Irregular compensation의 치료계획을 사용 시 가장 많이 들어가는 것으로 나타났으며, 이는 많은 MLC의 움직임에 의한 산란선 영향으로 생각된다. 모든 치료계획에서 피부의 위치에 따라 약간의 차이는 있으나 부족선량이 생기는 부분에서는 내측의 내유임파절(Intramammary lymph nodes)선량이나 Scar, Drain site등에서 세심한 주의가 필요하다. 부족선량을 높이기위해서는 Dose fluence를 이용한 Irregular compensation의 치료계획을 사용하는 것이 좋겠으나, 전체적인 선량을 높이기보다는 선택적인 범위내에서 선량을 높이게 되므로 환자의 연령이나 움짐임 등을 고려하여 치료기술을 선택하는 것이 바람직할 것으로 사료된다.

Most VE operation related to construction project is progressed in stage of planing or design phase, especially in case of domestic. It is encouraging fact and if you have VE process in stage of planning and design, you'll have experience a reduction of about 70% of total saving cost in which total construction process may occurred. However, recently the work of construction in overseas increase and almost is only construction-work, except planning and design process. As this reason, VE process for construction-work phase only is demanded in high necessity. VE in construction phase comes to accomplish intensively in the part which the design change does not follow, through know-how, equipment operating method and method of temporary-structure erection at the established construction-site learned, builders will be the possibility of reduction from 3% to 10% in constructive expense. This paper describes VE performing example in OO company's construction-work phase, and propose the methodology of VE performance in the phase of construction. And also it is aimed to extending VE applications into the overseas construction enterprise.
