국립공원은 주로 산악 지형 내 조성되어 있으므로 산사태에 의한 피해 가능성을 항상 내포하고 있다. 본 연구는 산사태 연구의 일환으로 국립공원 탐방로 내 위험 급경사지를 체계적으로 유지관리하기 위한 방안을 마련하는데 목적이 있다. 국립공원에 특화된 자체 체크리스트를 제작하였으며, 전국 19개 국립공원 183개소 급경사지에 대한 실태조사가 이루어졌다. 실태조사의 최종 목적은 위험 급경사지에 대한 안정화 대책을 마련하는 것으로 현장조사와 안정해석의 과정을 거친다. 일부 급경사지에서는 위험성 판단을 위해 지상라이다 등 특수 장비를 이용한 조사를 시도하였다. 중장기 정비계획을 위한 투자우선순위 공식을 개발하였으며, 현장자료를 이용한 순위 및 위험등급을 산출하였다. 최종적으로 위험 급경사지의 향후 체계적인 관리를 위해 “국립공원 급경사지 유지관리시스템”을 개발하였으며, 모든 현장자료들은 시스템 내 DB화 되었다. National parks, which are located mainly in mountainous areas, are always at risk of damage by landslides. The goal of this study is to establish a method for systematically maintaining hazardous steep slopes along trails in national parks. We produced a checklist suitable for each of the 19 national parks nationwide and investigated 183 slopes. The aim of these investigations is to recommend appropriate slope-stability countermeasures, including field investigations and stability analysis. We made preliminary investigations at specific sites, evaluating the slope hazard using specialized equipment such as terrestrial LiDAR. An investment priority formula was developed, and ranking and hazardous grades were calculated as part of a long-term maintenance plan. Finally, to systematically manage dangerous slopes and to house all the field data within one system, we developed the “Slope Maintenance System in National Parks” based on web server that can show various information for slopes.

It is widely known that compare to many other countries, the U.S.A. has a strong framework for efficient implementation of mitigation policy to protect wetlands. As indicated in many strong mitigation initiatives, mitigation policy primary requires avoidance rule for wetland damage and if a developer inevitability damages wetlands, the development should be minimize, and as a last resort, the policy impose legal duty that a developer should compensate wetland corresponding to the damaged wetlands. However, the legal system fur Korea's mitigation system does not provide any legal duty for the compensatory mitigation, although the possibility of creation of tidal flat is casually expressed in several Korean legal systems. Therefore, without any strong and enforceable legal system, Korean mitigation system cannot efficiently protect Korea's vast and productive wetlands. To introduce mitigation policy similar to the U.S.A. in Korea, we suggest that there (a) should be a strongly policy which regulate legal duty for the compensatory mitigation, (b) should be an improve management system for actively corresponding to special knowledge relating to environment, and lastly, (c) should be a system which consider a class action introduced in environmental regime for a long term protection of tidal wetlands for future generation.

Among various gyroscopes, the vibrating gyroscope has advantages such as compact size, mass-productivity and low cost. However this kind of gyroscope usually suffer from low linearity and low signal to noise ratio. Therefore, it is necessary to study on vibrating gyroscope to improve performance. In this paper, triangular cross section si selected in consideration for several points. The existing designs of exciting and sensing have some problems such that small signal size and low linearity. This paper proposes new design of exciting and sensing which is named one period exciting and the other period sensing. This design improves signal size, but it cannot improve linearity. This is because above two designs are the same open-loop type. So, another new design is proposed, which is named rebalancing, is applied to one period exciting and the other period sensing. This design are closed-loop type. It feedbacks the output signal. According to control theory, it can improve linearity. The circuits of each design are realized and used to calibration test. Calibration results show that new design of rebalancing improves linearity and signal size.

Background: The use of neurolytic agents to control neuropathic pain has been described from the last century Phenol and ethyl alcohol have been widely used as neurolytic agents, however, their neurolytic effect is variable in efficacy and duration of action, and infrequently accompanied with grave complications. It has been found that 5% lidocaine causes irreversible conduction blockade in animal studies. The goal of this study was to evaluate the neurolytic effect of 5%o lidocaine on various neuropathic pain syndromes for prolonged analgesia. Methods: Twenty-five patients with a diagnosis of neuropathic pain including trigeminal neuralgia (n = 7), postherpetic neuralgia (n = 10), and postsurgical neuralgia (n = 8) were selected after failure of routine therapeutic regimens. After performing a diagnostic nerve block with 1% lidocaine and 5% lidocaine was injected. The patients were followed for 6 months. Visual analog scale (VAS) scores and side effects were recorded for each patients. Results: A significant decrease in pain scores after neurolytic blockade with 5% lidocaine was seen in all of three pain groups. All the patients reported immediate and prolonged pain relief lasting from 4 weeks to 6 months. None of patients exhibited any appreciable side effects or complications. Conclusions: We suggest that 5% lidocaine may be used safely and effectively for the purpose of prolonged analgesia in selected patients with intractable neuropathic pain syndromes.

Objectives : Metabolic syndrome (MetS) is associated with increasing risk of cardiovascular morbidity and mortality but the risk of stroke associated with the MetS is less well established. The objective of this study was to evaluate the prevalence of MetS in stroke patients. Methods : We analyzed the data of 806 patients with acute ischemic stroke from Hanbang Stroke Registry supported by the Ministry of Science and Technology of Korea. Subjects' enrollment was done in the oriental medical hospitals of 4 universities located in the metropolitan region from April 2007 to August 2008. We analyzed all registered data and evaluated the prevalence of MetS and specific components of MetS. Results : The prevalence of MetS in stroke patients according to American Heart Association/National Heart Lung and Blood Institute (AHA/NHLBI) criteria was 59.6%. The prevalence according to the International Diabetes Federation (IDF) criteria was 41.6%. The prevalence of female patients was higher than that of male patients (71.8% vs 51% by AHA/NHLBI criteria; 61.7% vs 27.7% by IDF criteria). The prevalence of central obesity, low HDL cholesterol and hypertension was higher in female patients. There was no significant relationship between MetS and stroke subtype. Conclusions : This work gives us the basic data on the association between MetS and risk of stroke. There should be the prospective cohort studies to evaluate MetS and the risk of stroke.

해저열수광상은 황화물 미네랄이 해저의 열수작용을 통해 형성된 광상을 의미하며 특히, 구리, 납, 아연, 금, 은 등의 금속이 다량 포함되어 있다. 현재 해저열수광상 개발분야의 선두주자는 노틸러스사이다. 노틸러스사는 파푸아뉴기니, 피지, 통가, 솔로몬제도, 뉴질랜드 등 남서태평양 도서국에 약 37만 $km^2$에 달하는 탐사권을 보유 또는 신청해 놓은 상태이다. 넵튠사 역시 뉴질랜드, 파푸아뉴기니, 마이크로네시아에서 27만 $km^2$가 넘는 면적의 탐사권을 취득하였다. 이들 두 광업회사는 2010년 세계 최초로 해저열수광상의 상업생산을 목표로 적극적인 활동을 전개하고 있다. 주변국가인 중국과 일본은 전략광물의 안정적 공급을 위하여 해저열수광상 탐사활동을 적극적으로 수행하고 있는 실정이다. 중국의 경우 중국대양협회를 통해 전 지구 대양을 대상으로 심해저자원개발을 위한 국가연구개발사업을 수행하고 있다. 일본의 경우 자국의 EEZ를 중심으로 해저열수광상 조사사업을 수행하고 있다. 이러한 국제적인 해저열수광상 개발동향을 고려하여 우리나라의 해저열수광상 개발을 위한 전략방향을 소관부처의 일원화와 법제도 정비, 사업추진주체 결정, 정부의 적극적 예산지원, 해저열수광상 개발을 위한 중장기 계획수립 등의 측면에서 제안하였다. Polymetallic sulphides means hydrothermally formed deposits of sulphide minerals which contain concentrations of metals including, inter alia, copper, lead, zinc, gold and silver. Nautilus is the first company to commercially explore the seafloor polymetallic sulphide deposits. The Company holds exploration licences and exploration applications for more than 370,000 $km^2$ in the jurisdictional seas of Papua New Guinea, Fiji, Tonga, the Solomon Islands and New Zealand along the western Pacific Ocean's Rim of Fire. Neptune Minerals is also a leading explorer and developer in this field, with exploration licences awarded totalling more than 270,000 $km^2$ in the territorial seas or EEZ of New Zealand, Papua New Guinea and the Federated States of Micronesia. These two companies now carry out the most active investment activities for seafloor polymetallic sulphide deposits with a goal of commercial production by 2010. China and Japan carry out exploration activities for the seafloor polymetallic sulphide deposits to secure supplies of strategic metals. China carries out national R&D projects relating to deep sea mineral resources in the world ocean through China Ocean Mineral Resources R&D Association(COMRA). And Japan investigates her own EEZ for exploration of the seafloor polymetallic sulphide deposits. In consideration of aforementioned international activities of coastal nations as well as private companies for exploring the sulphide deposits, Korea shall prepare strategic plans : First, consolidation of the authorities concerned and legislative support; second, determination of main entity of the project; third, securing government's decisive investment of sufficient budget; and lastly, establishment of the mid, long-term plan for development of seafloor polymetallic sulphides deposits.
