  • 전국 시·도 및 시·군·구의 안전 관련 주요통계를 기반으로 사회재난은 지역안전지수 6개 분야(화재, 범죄, 교통사고, 생활안전, 자살, 감염병)에 대한 전국 지방자치단체의 지역안전지수 등급을 관리하여 개선대책을 수립 시행하고 있으며 자연재난은 자연재해 안전도 진단을 통해 관리체계를 운영하고 있다. 현재 적용하고 있는 자연재해 지역안전도 평가는 읍면동 지역 단위까지 자연재해 지역위험성 평가를 하기에는 내용이 매우 미흡한 실정이며, 지나치게 공학적이고 어렵게 표시되어있어 일반인들이 사용하는데 한계가 있다. 본 연구에서는 외국 선진국에서 주로 사용하는 자연재난과 사회재난이 혼합된 지역위험성평가 모형을 원형으로 하여 우리나라의 자연재난 지역위험성평가를 읍면동 하위 단위까지 확장된 개선 모형으로 제시하는데 목적이 있다.

  • Maintaining sea superiority through successful mission accomplishments of warships is being proved to be an important factor of winning a war, as in the Ukraine-Russia war. in order to ensure the ability of a warship to perform its duties, the survivability of the warship must be strengthened. In particular, among the survivability factors, vulnerability is closely related to a damage assessment, and these vulnerability data are used as basic data to measure the mission capability. The warship's mission capability is usually measured using a wargame model, but only the operational effects of a macroscopic view are measured with a theater level resolution. In order to analyze the effectiveness and efficiency of a weapon system in the context of advanced weapon systems and equipments, a warship's mission capability must be measured at the engagement level resolution. To this end, not the relationship between the displacement tonnage and the weight of warheads applied in the theater level model, but an engagement level resolution vulnerability assessment method that can specify physical and functional damage at the hit position should be applied. This study proposes a method of measuring a warship's mission capability by applying the warship vulnerability assessment method to the naval engagement level analysis model. The result can be used as basic data in developing engagement algorithms for effective and efficient operation tactics to be implemented from a single unit weapon system to multiple warships.

  • The development of reliable earthquake mitigation plans and seismic risk management procedures can only be based on the establishment of comprehensive earthquake hazard and loss scenarios. Two cities, Grevena (Greece) and D$\ddot{u}$zce (Turkey), were used as case studies in order to apply a comprehensive methodology for the vulnerability and loss assessment of lifelines. The methodology has the following distinctive phases: detailed inventory, identification of the typology of each component and system, evaluation of the probabilistic seismic hazard, geotechnical zonation, ground response analysis and estimation of the spatial distribution of seismic motion for different seismic scenarios, vulnerability analysis of the exposed elements at risk. Estimating adequate earthquake scenarios for different mean return periods, and selecting appropriate vulnerability functions, expected damages of the water and waste water systems in D$\ddot{u}$zce and of the roadway network and waste water system of Grevena are estimated and discussed; comparisons with observed earthquake damages are also made in the case of D$\ddot{u}$zce, proving the reliability and the efficiency of the proposed methodology. The results of the present study constitute a sound basis for the development of efficient loss scenarios for lifelines and infrastructure facilities in seismic prone areas. The first part of this paper, concerning the estimation of the seismic ground motions, has been utilized in the companion paper by Kappos et al. (2010) in the same journal.

  • 논산 개태사지석불입상(보물 제219호)은 담회색을 띠고 부분적으로 장석 반정을 함유하고 있는 중립 내지 조립질의 화강섬록암으로 구성되어 있다. 구성암석의 전암대자율은 평균 12.06(${\times}10^{-3}$ SI unit)으로 개태사지 배후의 천호산 ($0.19{\times}10^{-3}$ SI unit) 노두와는 많은 차이를 보이고 있어 석재의 외부 유입 가능성이 제기된다. 이 석불입상은 우협시불의 박리(35.2%), 본존불의 시멘트 보수물질(21.1%) 및 먼지(25.0%)가 주요한 손상현상으로 밝혀졌다. 초음파 속도는 본존불 2850.2m/s, 좌협시불 2648.4m/s, 우협시불 2644.5m/s로 측정되었다. 이를 통해 산정한 일축압축강도는 우협시불이, 부위별로는 대좌에서 상대적으로 낮은 강도를 나타내어 손상도 평가 결과와 일치하였다. 석불입상이 봉안된 보호각 내부의 연평균 기온은 $13.7^{\circ}C$, 상대습도는 79.0%로, 계절에 따른 보호각 내부의 환경 변화는 근본적으로 외부의 변화를 따르나 미기후 변동이 심하지 않아 비교적 안정된 실내 환경이 유지되고 있다. 석불입상의 대좌 표면에서는 봄과 여름철에 결로가 발생하는 것으로 확인되었으며, 겨울철에는 동결파괴가 우려된다. 이는 훼손도 평가와 초음파 탐사 결과에서 나타난 대좌의 풍화 및 강도 저하의 근본적인 요인일 가능성이 매우 크다. 따라서 봄과 여름철에 집중 강우 시 실내의 제습과 한겨울에 기온 강하를 저감시킬 수 있는 조치가 필요하다.

  • This research has a meaning to provide basic data for eco-friendly way of district unit plans and ecological landscape planning by evaluation of biotope preservation value at the level of district unit and designating land development of the site, the whole area of Sinseo-dong (Dong-gu, Daegu metropolitan city) for research site. The summary of analysis result is as follows. As a result of classification of biotope types on the research site, it is divided into 11 biotope groups such as a residential biotope group and 51 specific biotope types which is subordinate to the groups. As a result of the first value assessment on classified biotope types, there are 16 types of natural rivers which is full of vegetation as a I class. Also it is analysed as 9 types of IIclass, 14 of IIIclass, 8 of IVclass, and 4 of Vclass. In particular, in light of a wildlife habitat, EB, in case of broad-leaved tree of mixed forest assessed as a II class, was classified into Iclass which is one-step upgraded as a final class with the analysis as there is a structural characteristic (more than 71% of low density, 50 years of age-class). As a result of second assessment, it is analysed that there are 17 special sites (1a,1b) and 33 special sites (2a, 2b, 2c) respectively for preservation of species and biotope. Particularly, in case of the No. 27 space, it was assessed that it has the value of about medium (IIIclass) level, but its value was upgraded with the on-spot detailed investigation that most of Aristolochia contorta, designated as a rare plant by Ministry of Environment, is growing. It is regarded that the above-mentioned research result on evaluation of biotope preservation value is expected to provide very important basic materials for future district unit plans and smooth integration with landscape ecology plans and eco-friendly space development.

  • The aim of this study was to assess the people's need for visiting health services in a rural area. In recent years, the great concern for the visiting health services has aroused in Korea. Stratified cluster sample for a household survey was used to select 1,255(8.4%) Households from Yonchon county. This study was undertaken from July 26 to August 7 in 1993. Medically defined need, usually expressed by the prevalencies or rates of specific disease, was evaluated with the use of criteria established by medical and nursing professors and expressed by the percent of specific objects for the visiting health services. Perceived need represented by the acceptability for the visiting services and willingness to paying for it, also, evaluated. The major results were as follows : 1. Of the 348 patients with hypertension, 201 were the non-compliant patients, the rate of the non-compliant hypertension patients in 4,577 study population was 7.4%. 2. Of the 141 diabetic patients, 73 were the non-compliant patients, the rate of the non-compliant hypertension patients in 4,577 sample population was 2.7%. 3. The number of patients with severe musculo-skeletal disease was 24, the rate was 0.9% above the age 30. 4. Of the 514 elderly, 33 were the elderly without any family member, the rate was 8.4%. Those with severely decreased activity of daily living were 13. 5. Infants with high risks were 12, pregnant women and neonates were 5, patients discharged within 1 week and with special equipments such as peritoneal dialysis, stoma, TPN etc. were 17, and patients with cancer were 5. Total number of the objects needed visiting health services was 752(18.43%) of the 4,577 study population. Perceived need evaluated were as follows; The acceptance rate of visiting health services was 74.9%, The kinds of visiting health services such as family health protection and promotion, early detection of hypertension, physiotherapy, health education and counseling were needed in the order of high rate The price willing to pay for visiting health services per visit was about 3,000-5,000Won.

  • 본 연구는 사업장폐기물 소각시설의 운영에 대한 직접 및 간접 환경영향을 전과정평가 기법으로 평가하고 개선방안을 검토한 것이다. 소각시설에서 직접환경영향은 배출되는 오염물질이 처리공정에서 처리되어 공정을 거치면서 감소하였으나, 시설의 처리운영에 따른 자원과 에너지 사용으로 간접환경영향은 증가하여 직접영향 89.1%, 간접영향이 10.9%로 나타났다. 소각시설의 공정에 따른 환경영향은 소각로-반건식반 응탑-백필터공정 순으로 나타났으며, 이는 소각로에서는 폐기물이 소각되면서 대기오염물과 소각재가 발생되기 때문이다. 영향범주별 환경영향은 지구온난화-부영양화-자원고갈 순으로 나타났으나 지구온난화가 85%이상의 절대적 환경영향을 미치는 것으로 나타났다. 또한, 소각시설에서 소각열을 활용에 의한 회피효과를 검토한 결과, 스팀과 전기로 활용할 경우 각각 45.5%, 19.8%의 환경영향 저감을 얻을 수 있어, 소각로의 입지 선정 시 소각열의 효율적 활용이 중요하게 고려되어야 할 것으로 나타났다.
