Saturated marine clays are consolidated under applied loads caused by deposit-process or human interruptions. The consolidation process results in densification and in turn increment of the undrained strength of a clay deposit. In a clay deposit, the undrained strength is increasing with the effective overburden pressure, which also increases wit depth. The strength variations with effective overburden pressure(or depth) is characterized by so called "Cu/P" ratio. In korea, the empirical formula proposed by Skempton has been used to estimate the undrained strength profile of a clay deposit without any sometimes varification of the applicability to clay deposits in Korea. In the thesis, the test data for some clay deposits along south -west coast in Korea were analized to test the applicability of Skempton formula. A new formula pertinent to the deposits was developed. Also, Initial elastic and secant moduli were studied.

우리나라에서 NATM 통신구터널에 적용되고 있는 암반분류형태 및 지보패턴은 지하철 도시터널과 같이 대형단면 터널에 적용되는 기준을 그대로 적용하고 있는 실정이다. 그러나 NATM 통신구터널은 대개 소형단면터널이며 깊은 tal도에서 시공되는 것이 일반적이다. 따라서 NATM 통신구터널의 설계 및 시공시에는 적절한 지반암반의 정량화 및 공학적 분류법을 별도로 마련하여 이 분류에 근거한 적합한 지보모델을 제시할 필요가 있다. 본 연구에서는 NATM 통신터널에 적합한 표준지보패턴과 암반분류모델을 7등급으로 구분 제시하며 제시된 암반 분류등급별 지보패턴에 대한 합리성이 터널시공사례에 대한 유한차분해석을 통해 검증된다. The classification of rock-mass and its reinforcement pattern used for Communication Cable Vault in Korea have been actually used such methods that applied to largesectional tunnel construction such as Subway urban-tunneling. However, in the case of small sized tunnel works for Communication Cable Vault which are generally adopted at deep depth, the proper reinforcing support model should be suggested on the basis of quantitative classification of rock-mass for design and construction. This paper presented standard reinforcement pattern and classification model of rock-mass for NATM of Communication Cable Vault. They are divided in to 7-categories of grades and reasonability of these suggestion is ascertained from numerical analysis for the construction of these suggestion is ascertained from numerical analysis for the construction of Tunnel.

최근 우리나라의 지역개발이나 정책에 있어 과거의 중앙정부 중심, 물적 성장 중심의 개발 패러다임에서 벗어나 자립적 역량강화, 지역 간 연계협력, 융합화 등이 강조되고 있다. 이에 본 연구의 목적은 지방자치제가 실시되었으나 지방의 자치기반이 취약하여 지역간 불균형 발전이 심화되는 가운데, 박근혜정부의 출범과 함께 최근 국내외적으로 변화하고 있는 지역발전의 패러다임에 직면하여 지방분권과 균형발전에 토대를 둔 지역 주도의 자립적 지역발전을 이루기 위한 구체적 방안을 제시하는 데 있다. 이를 위해 시대적 요구와 필요성을 절감하고, 지역적 차원에서 창조경제에 기반한 새로운 지역발전 패러다임으로서 국민대통합과 지역균형발전을 지향하는 「지역순환형 자립발전모델」을 제시하였다. 이는 궁극적으로 국내외 패러다임의 변화를 체계적 이론적 틀로써 통합하고 실질적으로 적용하기 위한 것으로 지역을 중심으로 사람을 키우고, 청년을 살게 하고, 사람이 모이게 하는 것을 의미한다. 이를 달성하기 위한 구체적 전략으로서 선순환 전략과 자립전략을 제시하였다. 첫째, 지역순환형 자립발전의 토대가 되는 자립전략으로서 지역발전의 가치와 목적을 ‘지역역량강화(Competency)’. ‘연계협력(Cooperation)’, ‘융합(Convergence)’의 3C전략을 제시하였다. 둘째, 지역순환형 자립발전을 달성하기 위한 선순환 진흥전략으로서 지역교육 진흥, 지역산업진흥, 지역문화예술진흥, 지역복지진흥, 지역창조와 재생을 제시하였다. 첫 번째 전략은 우수 인재양성을 통한 지역교육 진흥(振興)이다 교육부문 진흥을 통해 우수한 인재를 양성하고 지역에 공급하는 시스템을 구축하는 것이다. 둘째, 일자리 창출을 위한 지역산업진흥(振興) 이다, 즉 산업부문 진흥을 통해 청년일자리 창출 및 역동적 지역창출에 기여하는 것이다. 셋째, 지역문화와 예술 기반 구축 및 역량 강화를 통해 지방문화예술을 진흥해 나가야 한다. 넷째, 지역복지역랑 강화를 위한 지역복지 진흥(振興) 이다. 지역복지 진흥을 통해 지역 복지 예산 및 인프라 구축 등을 통해 서민들이 피부로 느낄 수 있는 복지역량을 강화시켜나가야 할 것이다. 마지막으로 지역창조와 재생을 통해 관련 인프라를 확충하여 국토의 고른 공간 창출을 진흥시켜 나가야 할 것이다. Despite local government efforts for regional change, the local self-government based development is vulnerable to deepening disparities between regions. While confronting the paradigm of the latest changes in national and international development of the region that Park Geun-hye government faces, the purpose of this study is to present concrete plans for achieving self-sustaining regional development based on decentralization and balanced development. To this end, with the demands and needs of the times, “The Self-Supporting Development Model of the Regional Circulation” is proposed which professes national unification and balanced regional development as a new regional development paradigm which is based on the creative economy utilizing the local dimension. Ultimately, this is for integrating a domestic and foreign paradigm shift as a systematic theoretical framework and practically applying that in the field. It intends to accomplish this by educating people in the area, making them live in the area, and gathering people into the area. In order to achieve it, we proposed a virtuous and self-supporting development model. Firstly, for tile self-supporting development of the regional circulation, the 3C strategy-Competency, Cooperation, Convergence, Convergence-is proposed. Secondly, in order to achieve self-supporting development as a strategy for promoting regional circulation, we proposed promotion of regional education, regional industrial development, local cultural arts, and community welfare for the creation and regeneration of the region. The first strategy is through promotion of local education by fostering talented people in the regional area. Secondly, by creating jobs for local industrial development and contributing to the creation of a dynamic region. Thirdly, by empowering the local culture and building up the cultural grounds, through promotion of local art and culture. Fourthly, local social welfare should be promoted through community welfare budgets and appropriate infrastructure in order to strengthen the regional social welfare power. As a result, people will benefit through welfare empowerment. Lastly, enhancing the infrastructure through the creation and expansion in the reproduction of the region. As a result of the effort in making a well-balanced regional development, it is expected a well-balanced space development for the whole country.

Study Design : Spine fusion with fixation procedure is associated with substantial operative blood loss, which frequently necessitates transfusion. The authors evaluated the safety and efficacy of intraoperative autotransfusion using Cell Saver during spinal surgery. Summary of Literature Review : It has been reported that the contraindications to the use of intraoperative autologous transfusion are malignancy, infection, and gross wound contamination. Objectives : The purpose of this study was to evaluate the safety and efficacy of intraoperative autotransfusion using Cell Saver during spine surgery. Material and Methods : We retrospectively reviewed 62 patients who had operation for lumbosacral spinal stenosis and hypotensive anesthesia. Among them, Group Ⅰwhich received autotrans fusion using Cell Savers included 26 patients with fusion of 2 segments, and Group Ⅱ as control group included 13 patients. Group Ⅲ which received autotransfusion using Cell Savers included 17 patients with function of 3 segments, and Group Ⅳ as control group included 6 patients. We analyzed the amount of intraoperative blood salvage using a Cell Saver, the amount of total homologous transfusion amount, intraoperative blood loss, the amount of postoperative drainage amount and perioperative changes of hemoglobin, hematocrit and platelet count. Results : There was no statistical significance between Cell-Saver group and control group in amount of total homologous transfusion and intraoperative(except in 2 segment of fusion using cell saver: 86.5% increased) & postoperative blood loss(p>0.05). The circulatory balance(amount of intraoperative blood salvage using a Cell Saver plus amount of total homologous transfusion minus amount of total blood loss) was statistical significance between Cell-Saver group and Control group. The Cell-Saver group had positive balance and Control group had negative balance. There were no statistical differance in the evolusion of hemoglobin, hematoocrit and platelet count between Cell-Saver group and Control group(p>0.05). There was no transfusion reaction and thromboembolic disease in all group. Conclusion : In retrospective study, Cell Savers was safe and immediate availability in orthopedic surgery such as spinal surgery. It was effective methods for storing a sufficient volume of blood for spine surgery without affecting the patient's postoperative hemodynamic ststes, too. It was possible to operation without intraoperative homologous blood transfusion in 2 or 3 segment fusion. We may need further study.

Constipation is one of the most common functional digestive complaints worldwide. We investigated the laxative effects of figs (Ficus carica L) in a beagle model of constipation induced by high protein diet and movement restriction. The experiments were consecutively conducted over 9 weeks divided into 3 periods of 3 weeks each. All 16 beagles were subjected to a non-treatment (control) period, a constipation induction period, and a fig paste treatment period. We administered fig paste (12 g/kg daily, by gavage) for 3 weeks following a 3-week period of constipation induction in dogs. Segmental colonic transit time (CTT) was measured by counting radiopaque markers (Kolomark) using a radiograph performed every 6 h after feeding Kolomark capsules, until capsules were no longer observed. Fig paste significantly increased fecal quantity in constipated dogs, and segmental CTT was also reduced following fig paste administration. There were no significant differences in feed intake, water intake, body weight, or blood test results, between the constipation and fig paste administration periods. Our results demonstrate that fig is an effective treatment for constipation in beagles. Specifically, stool weight increased and segmental CTT decreased. Fig pastes may be useful as a complementary medicine in humans suffering from chronic constipation.
