The floristic characteristics and ecological conservation measures for the plant resources of the Tokyusan National Park. Chollapuk-do, Korea were discussed. The field works was done for three times in nine major areas from April to July, 1993. The total number of vascular plants in this area were summarized as 97 families, 297 genera, 469 species and 541 kinds. The nineteen kinds of artificially planted, twelve kinds of Korean endemics and sixteen kinds of Korean rare and endangered species in the area were revised and compiled in the list. The flora of the area were categorized into the Southern part of the Korean Region, where the species such as Quercus serrata. Fraxinus sieboldiana, Ilex macropoda, Lindera erythrocarpa, Lindera glauca, Rubus coreanus, Taxus cuspidata, Cephalotaxus koreana and Abies koreana were roled as major floristic components in the Korean Region and endemized in the southern part of Korea. The natural communities such as Adonis amurensis Community, Taxus cuspidata Community, Betula ermanii Community, Hemerocalis spp. Community, Rhododendron tschnoskii Community, Rhododendron schlippenbachii Community, Disporum ovale Community, Tricyrtis dilatata Community, and present natural distribution of Abies koreana, and swamp vegetation in Tumunsan areas, as well as upland grassland at the summit of Hyangchokpong were represented for their floristic values in the area. The fifteen kinds of medicinal plants such as Gastrodia elata, seven kinds of ornamental plants such as Adonis amurensis, and thirteen kinds of edible plants such as Ligularia fischeri are faced potentially in endangered from the outrageous collections by the local peoples. The Action Plan for the conservation management of the area which enables sustainable use by the local peoples must be established in the near future.

Emergencies and disasters can happen any time without any warning, and things can change and escalate very quickly, and often it is swift and decisive actions that make all the difference. It is a responsibility of the building facility management to ensure that a proven evacuation plan in place to cover various worst scenario to handled automatically inside the facility. To mapping out optimal safe escape routes is a straightforward undertaking, but does not necessarily guarantee residents the highest level of protection. The emergency evacuation navigation approach is a state-of-the-art that designed to evacuate human livings during an emergencies based on real-time decisions using live sensory data with pre-defined optimum path finding algorithm. The poor decision on causalities and guidance may apparently end the evacuation process and cannot then be remedied. This paper propose a cloud connected emergency evacuation system model to react dynamically to changes in the environment in emergency for safest emergency evacuation using IoT based emergency exit sign system. In the previous researches shows that the performance of optimal routing algorithms for evacuation purposes are more sensitive to the initial distribution of evacuees, the occupancy levels, and the type and level of emergency situations. The heuristic-based evacuees routing algorithms have a problem with the choice of certain parameters which causes evacuation process in real-time. Therefore, this paper proposes an evacuee routing algorithm that optimizes evacuation by making using high computational power of cloud servers. The proposed algorithm is evaluated via a cloud-based simulator with different "simulated casualties" are then re-routed using a Dijkstra's algorithm to obtain new safe emergency evacuation paths against guiding evacuees with a predetermined routing algorithm for them to emergency exits. The performance of proposed approach can be iterated as long as corrective action is still possible and give safe evacuation paths and dynamically configure the emergency exit signs to react for real-time instantaneous safe evacuation guidance.

The aim of the this study is to observer paradoxal phenomenon in media election. The media, especially Television, was traditionally a journalistic operation representing political events on the outside of political camp. But recently, it intervenes to 'the political camp' as the most important method for election campaign. A centripetal of electronic medias making the dominant political space offer an alternative plan which get over the modern crisis of representative democracy. Even though, to the production of the political symbol and the operation of symbol which constitute substantial system of political action, the human being subject is excluded and the technical system of communication make up a govern structure. So it makes the contradictory situation. TV broadcast for election campaigning show well this paradoxal situation. The institutionalization of electoral broadcasting oriented by the State strengthens an immensification, an economical and political efficiency and a transparency of electoral campaign. But the means which controls the mind of public is also strengthened. It relates the production and circulation of the political symbol and the symbolic image restricted by dominator. In conclusion, this study argues that the media election is institutionalized by the instrumental reason(procedural rationality of politics and technological rationality of broadcasting), therefore the candidate take a fragment roles for the production of transcendental political symbol and the voters accommodate to the symbolic images which are foreseen and they judge.

국내에서는 최근 지구온난화에 따른 전 지구적 이상홍수의 발생으로 댐 붕괴 우려가 증대되고 있고, 이에 따른 주민들의 불안감도 고조되고 있는 상황이다. 특히 최근 집중호우의 증가와 태풍의 영향으로 대규모 수공 구조물의 설계빈도를 초월하는 폭우를 동반하고 있다. 실례로 20세기 들어 전 세계적으로 약 200건 이상의 댐 붕괴 사고가 발생하여 댐 하류 지역에 막대한 인명 및 재산피해가 발생하였다. 국내의 경우 "연천댐", "장현, 동막저수지" 붕괴 등과 외국의 경우 이탈리아의 Vaiont 댐과 미국의 Teton 댐 등의 사례가 있다. 이처럼 댐은 설계홍수량 이하의 경우에는 비교적 안전하게 홍수를 예방할 수 있으나 이보다 큰 규모의 홍수가 발생할 경우 그 피해 또한 엄청나다. 따라서 댐 붕괴 등의 비상상황이 발생하였을 때 하류 지역의 생명과 재산 손실을 최소화하고 댐의 물리적, 지형적, 구조적 특성에 따른 비상상황을 예상하고 이에 효율적으로 대처하기 위해 비상대처계획(Emergency Action Plan, EAP)과 같은 대책을 수립하게 되었다. 이에 본 연구는 댐의 비상대처계획 수립시 중요한 사항 중 하나인 홍수류 해석을 실시하였다. 현재 국내에서 댐 붕괴 홍수류 해석은 주로 그 안전성과 정확성이 검증된 Fread(1984)의 1차원 모형인 DAMBRK 모형을 이용하여 댐 붕괴 홍수류 해석을 실시하고 있다. 이 DAMBRK 모형을 이용하여 실제 붕괴 사례인 1982년 미국 콜로라도에서 발생한 Lawn Lake 댐의 붕괴 홍수류 해석을 실시하였다. Lawn Lake 댐은 콜로라도 록키 마운틴 국립공원에 위치한 약 8m 높이의 필댐으로 댐 붕괴로 인하여 830,000 의 물이 유출되었으며, 3명이 사망하고 3,100만달러의 손해를 일으켰다. 다음과 같은 실제 붕괴 사례를 댐의 제원과 홍수량을 이용하여 DAMBRK 모의를 실시하였으며 모의한 결과와 실측치와의 비교를 해보았다. 본 연구에서 모의한 결과는 댐 최대 붕괴 유출량은 잘 나타내었지만, 지점별 최대 유량 및 홍수파 도달시간에 관련해서는 다소 차이를 보였다. 이는 조도계수의 변화에 따라 지점별 최대 유량과 홍수파 도달시간, 그리고 홍수위가 달라지는 것임을 확인하였고 실제로 Lawn Lake 댐이 붕괴되어 흘러들어가는 Roaring 강의 댐 붕괴 잔해나 하상 변화를 모르기 때문에 조도계수의 실측치는 모의값 보다 훨씬 클 것으로 예상된다. 본 연구를 통해 비상대처계획 수립시 홍수류 해석을 할 때 조도계수의 변화에 따라 모의 결과 및 범람범위가 달라질 수 있으니 조도계수의 채택에 있어 신중하고 정확한 판단이 필요할 것으로 판단된다.

The number of traffic accidents at intersections has been increased over the past decade, and in 2014, accounted for 44% of the total traffic accidents. In addition, since most of road accident black spots include signalized intersections, the improvement of safety on signalized intersection is top priority for national road safety program in Korea. For the decision of most effective action plan for the safety of signalized intersection, this study conducted meta-analyses to assess the effects of various road safety facilities at signalized intersection on traffic accidents. We selected 19 articles regarding the prediction of traffic accidents at signalized intersection and calculated 34 individual effect sizes on 8 variables included in the articles. The results found that there was a statistically significant negative relationship between the occurrence of traffic accident and the presence of all of road safety facilities except an exclusive left turn bay. It shows that most of the road safety facilities could prevent traffic accidents, and intersection channelization has the most effective on the reduction of traffic accidents followed by left-turn acceleration lane, lightning, crosswalk, exclusive right-turn lane and median barrier.

The purpose of this study is to analyze governance in the business processes of Jeju's proposed 'Happy Living Area.' This study found Jeju's 'Happy Living Area' plans for governance were realized and conflicts may frequently occur in future business processes. Furthermore, roles and support systems were measured for the development council of 'Happy Living Area.' This paper reports findings from a case study on community planning for a public art project. This study recommends public-private governance in terms of process factors as well as role considerations. With respect to process factors, administrative agencies and citizen participation are examined. Second, the Living Area Council should play a mediating role between central and local governments as well as residents. Third, Happy Living Zones' Advisory Centre should undertake an advisory role. Fourth, consultation between public and private sectors is needed to establish evaluation criteria for reviewing proposals from subordinate administrative agencies. Fifth, local government systems should be managed by autonomous municipalities. Concerning role considerations, a new 'Personality for Governance' position should be established for performing different roles in the project implementation stage.

Civil complaints and lawsuits filed in the process of providing emergency medical service include fall accident on the way of carrying the patient, transfer consent, refusal and rejection of rescue request, range and behavior restriction of emergency medical technicians, false registry of logbook, neglect of duty and emergency patient, and violation of traffic laws on the way of dispatch to the scene of accident. This study suggested the measures by cases as follows. 1. The accidents on the way of carrying a patient could be divided into fall of patient and fall by paramedic's mistake. In the former case, damages caused by the ambulance's shaking must be notified to the patient and guardian and recommended to fasten seat belt, in the latter case, the plan of patient's posture, route of transport, rescue and equipments should be comfirmed before fixing the patient. 2. Transfer consent must be made as implied when the patient is unconscious under delusion and was not able to consent physically, and paramedic must take an action by his judgment and record details of services on logbook. 3. When a patient refused to transfer, get 'confirmation of transfer refusal' and inform him of refusal. Paramedic should receive the signature. In addition, in case of refusal, transfer request should be made after hearing doctor's opinion and it should be notified to transfer request and superintendent of fire station after making 'confirmation of transfer refusal'. 4. Emergency medical technicians should perform their duties within the range of services prescribed by Article 41 of Law of Emergency Medical Service and Article 33 of Its Enforcement Regulations and shall not make announcement of death. In case of reporting the death to guardian, it is desirable to use record data like ECG results. 5. The best way to have protection from legal problems is making and keeping the exact records of accident and patient. Paramedic should not mention his subjective opinion about the accident-related matter. He must record correctly and keep the original medical records. 6. As emergency medical technicians are responsible for taking care of emergency patients, they must contact a briefing room when they meet a difficult situation suddenly due to vehicle stop or treatment of other patients and then must have support from neighboring hospital and other safety centers. 7. Since the ambulance operator is responsible for safety and careful driving of ambulance, he must be careful when he violates traffic regulations unavoidably. The operator should drive slowly below 10km/h at an intersection and pass it after getting way from general vehicles driving from all directions.

우리나라의 간척사업은 고려시대 중엽부터 서남해안에 다수 산재되어 있는 천혜적인 간척 적지를 대상으로 지속적으로 추진되어 국토확장 및 식량 자급달성에 기여하여 왔다. 그러나, 최근 들어 쌀 수급 등 농업정책의 변화, 비용에 대한 경제성 평가의 변화, 개발과 보전에 관한 이해당사자간의 대립 등으로 신규 간척사업의 추진이 어려워지고 기존 간척지의 토지이용 목적 변화와 이치수 기능개선을 목적으로 배수갑문을 확장하는 등의 사업이 추진되고 있다. 본 연구에서는 방조제 상류지역 및 지천에서 이상홍수 유입에 따른 방조제 안정성 검토를 실시하였다. 호내로 유입되는 빈도별 홍수량에 따른 각 지점별 수위변화를 이용하여 방조제 비상대처계획에 대한 재난관리 지표로 활용할 수 있는지를 확인한다. 이를 위해 선정된 방조제를 중심으로 빈도별 홍수량을 산정하여 수문학적 안정성을 검토하고, 빈도별 홍수량에 따른 호내의 홍수위 변화를 통하여 비상대처계획 시나리오를 구성하고자 한다. 새만금 유역의 수치모델링에 필요한 범위를 설정하고, 모델 구성 및 자료를 입력한 후 검 보정을 통하여 모델의 신뢰성을 검증한 후 모델운영 조건을 설정하였다. 새만금 종합개발계획(MP)이 완료되었을 경우를 가정하여 통합운영을 실시하였다. 호내 관리수위에 따른 100, 200, 500, PMF 홍수량 유입시에 호내 홍수위 모의를 수행하였다. 또한, 비상단계 중 초기단계인 '관심단계'를 "이상홍수 발생부터 관리수위 EL-1.5m까지"로 설정한다면 방조제 초기 재난대응이 유리해 질 것으로 판단된다. 또한, '주의단계'는 "관리수위 EL-1.5m부터 호내 관리홍수위 EL+1.5m까지"로 '경계단계'를 "호내 관리홍수위 EL+1.5m부터 제당 내측사석보호공 홍수위까지", '심각단계'를 "제당 내측사석보호공(만경유역 EL+4.5m, 동진유역 EL+2.5m) 이상의 홍수위"로 설정한다면 방조제 관리자에게 세부화된 정보 및 지표를 제공해 줄 것이라 판단된다. 방조제 비상상황 단계별 분류에서 이상홍수위 발생후의 시간을 수치모의를 통해 구분하였으며 정성적인 위기상황 판단이 아닌 구체적인 수치로 된 지표들을 방조제 위기상황 재난지표로 활용한다면 상황 관리자의 위기상황 판단과 대처를 위한 의사결정에 도움이 될 것으로 기대한다.
