도시의 개발을 통한 발전방향은 지역별 기술력을 바탕으로 시대의 흐름과 문화, 경제, 도시정책 등에 따라 다양하다. 특히, 워터프론트는 도시와 가장 근접한 친수공간으로 단어자체에 도시'라는 개념이 포함되어 있다. 즉 도시가 큰 강이나 바다, 호수 등과 접하고 있는 공간을 말한다. 우리나라는 도시계획차원에서 도시 수변공간(urban waterfront)으로 설정하고, 레크레이션, 공원, 경관형성, 환경오염 저감, 정서함양, 생산 등의 다양한 기능을 갖고 있는 매우 공공성이 높은 도시지역의 주요 공간지역으로 의미를 부여하고 있다. 그러나 워터프론트를 개발계획을 수립하는 과정에서 교통계획, 홍수 등의 재해시설, 환경 등에 대한 평가가 제대로 이루어지지 않고 있으며(한국일보, 2011), 개발 계획 추진은 주민 공감대 형성, 사업타당성 검토 없는 '밀어부치기식' 개발 지상주의로 전락하고 있다. 따라서 본 연구는 국내 워터프론트 개발사업 계획을 추진하고 있는 지역으로 인천 송도지역과 부산의 수산시장으로 유명한 자갈치시장 일대의 개발계획, 마산 도시재생지구의 항만 재개발계획 사례를 분석하여 개발계획의 문제점과 언론상에 비춰지는 개발의 현 실태, 지역개발의 효과 등에 대한 시사점을 도출하였다. 사례지역을 비롯한 대부분의 기존 워터프론트 개발은 경제성을 위해 규모가 큰 상업시설 위주로 개발이 이루어지고 있으며, 주거시설이나 문화시설을 비롯한 다양한 시설의 구성이 부족한 특수성을 갖추어 가고 있다. 또한, 기존의 유휴공간을 재개발하면서 도시와의 관계를 제대로 설정하지 못하여 도시와 분리된 폐쇄공간으로 개발이 이루어지고 있으며, 도시구조에 통합되지 못하고 있는 실정이다. 무엇보다 워터프론트 개발사업에 관계된 여러 집단들, 즉 중앙정부, 지방자치단체, 개발주체, 시민 등 이들 사이에 합의 도출의 어려움이 많아 좋은 계획안이 무산되거나 사업이 지체 혹은 중단되는 사례가 많았다. 워터프론트 개발에 대한 지역민사회의 충분한 공감대가 결코 형성되지 않았음에도 오히려 요식적 여론수렴 절차를 강조하고 있으며, 친환경적 도시개발이라는 사업의 목적과 맞지 않는 계획이 많았다. 특히, 관련 사업 중 항만재개발사업에는 막대한 초기 투자비가 소요되어 재개발사업을 위한 자금의 확보가 어려운 경우가 많이 있었으며, 도시의 장기발전계획과 통합된 장기적인 개발전략이 필요한데 이를 소홀히 하는 경우가 있었다. 본 연구를 통해 기존 워터프론트 개발계획의 문제점과 향후 정비계획이 추구해야 하는 친수구역의 관리방법, 주민참여 방안의 대안제시가 이루어 질 수 있었으며, 이를 바탕으로 국내 친수공간 정비계획을 재 고찰 할 수 있는 기회가 되었으면 한다.

An estuary is semi-inclosed inlets, located between terrestrial and marine environment. Since many estuaries along south-western coasts of Korean peninsula were affected by human settlements and activities, significant changes in sedimentation environments have been observed. The research area is divided into three distinct morpho-stratigraphic units: fluvial dominated area(Area1), mixed area(Area 2), tide-dominated area(Area3). The landform of this area has been changed by reclamation and river channel change. Temporal variations affected by dam construction, periodic freshet was iterrupted. Sediments began to continuously accmulate on estuary banks by tide. Meanwhile, because of the continuous but reduced discharge of fresh water, the salinity of estuarine sediments was declined. That processes made vegetated area( Phregmites lonivalvis and Suaeda japonica) to be expanded. It indicates that the magnitude and frequency of geomorphic processes has been significantly changed.

Recently our nature of environment has destroyed by a large scaled forest fire. In order to manage these forest fires, forecasting of it is considered as the most important thing. In this paper the database related to forest fire was first built and the efficient forest fire information management system was implemented by using GIS. The main goal of this system is that forest fire managers have GUI(graphic user interface) to analyze data of forest fire effectively and update and retrieve information in database. For the efficient GUI, this system is built in Visual Basic 6.0 and Map Object 2.0. Map Object 2.0 is combined to have various and powerful functionality of GIS analysis as component ware. The Oracle 8.0 is used as DBMS in this study to manage all the spatial and attributed information in database effectively. In the future, this system will play a critical role as making a decision supporting system for scientific forest fire protection and help real time forest fire hazard information offers service for public welfare administration business management.

Parks became a matter of concerned among urban planning facilities that have not been executed for a long time because of the judgement of constitutional disagreement. This study deals with actual condition of constructing neighborhood park at the level of urban planning. In order to enhance the coefficient of citizens' utilization of parks. This study analyzes current situation of neighborhood parks and developing condition in Busan, revealing problems by investigating types of facilities under construction as well as by comparing size and progress of the parks under construction. This study tries different kind of access to the problems with the emphasis on estimation of planning and establishing neighborhood parks on the basis of the coefficient of citizens' utilization. Through the various examinations, this study brings into relief the problems being created in the course of establishment of parks which functions only as green tracts of land at present. As a result, the following conclusions could be made. First, from the viewpoint of location the parks, Busan parks are mostly located in the mountain areas adjacent to urban districts. Secondly, establishment of neighborhood parks is usually for development projects and the facilities introduced in them are monotonous. Thirdly, there is a tendency towards expansion of size and standardization of facility. Forthly, establishment plan of parks lacks profitability. Lastly, there is serious limitation in the size of land for developing neighborhood parks, and what is worse, there is no management of them.

Traffic jam densified day by day is phenomenon to occur lack of the road capacity in comparison with traffic density, but lack of the road cannot be concluded by main cause of traffic ism. Because the central function of a city would be concentrated upon the downtown and traffic demand would not be evenly distributed by the classification of an hour. Therefore, this study based on the fact that each driver will select the route generating traffic delay very low when path choice from origin to destination in travel plan estimating the quality of passage could be maintained the speed he want will approach to a characteristic grasp of a road, traffic, driver changing every moment by traffic-demand of road increased as a geometrical series with analysis a classification of a street, a intersection along the path on traffic density and highway capacity analysis the path using GIS techniques about complex street network, also will get the path of actual optimum for traffic delay trend creating under various condition the classification per a hour, a day of week and an incident through network such as analysis for traffic generation zone adjacent about street, intersection, afterward will expect the result increasing efficiency of the road-use through a good distribution of traffic by optimum-path choice, accordingly will prepare the scientific, objective, appropriate basis to decide the reasonable time of a road-widen and expansion through section analysis along a rate of traffic volume vs. road capacity.

Abroad warships are confronted with various menaces. The most critical threat of the warship is an Anti-Ship Missile (ASM). The ASM is able to be launched at a variety of environments and platforms. The ASM can evades conventional naval radar systems and electronic countermeasure techniques for providing a fatal damage to the warship. To cope with the ASM, an active decoy is an effective method to minimize the direct damage to the warship. The active decoy increases survivability of the warship because the ASM can lure pursuit of the active decoy instead of the warship. In this paper, our proposed method verifies an available response time of the active decoy to deal with the ASM using the active decoy of the warship in marine environments. We defined models of the warship, the ASM, and the active decoy, and executed simulation by combining the models. By the simulation result, the proposed method demonstrated the superiority of the mobile active decoy of the response time decoy among various active decoys, and estimated a protection area to prevent the ASM according the response time of the mobile active decoy against the ASM.

Water, waste, electric and gas facilities are urban based facilities that needed in our life and are often located in underground. Therefore, underground facilities are more difficult to manage efficiently than ground facilities. It is needed to carry out survey/probe into underground facilities and to build database in order to prevent city-misfortunes being occurred because of negligent management and in order to minimize budget-waste and a traffic jam according to repetition of road excavation constructions. Also, the development of application system is required to manage efficiently underground facility. Chonju city has launched underground water supply facility computerizing project as a part of National Geographic Information System project until December 1998 and executed survey/probe into 402.89 km water supply that is 80 mm up inside central town area 39.6 $km^2$. Also, chonju city built database into 537 km water supply that is 80 mm below based on water supply card without other survey/probe works. Also, existing work process each department is changed into GIS applied work process and underground water supply facility management system is developed by its work process basis. Water supply underground facility management system that is developed is composed of sub-system like base-map management, water supply inspect, water supply management and water supply inquiry, construction work management, administration management and map management. This research presents the procedure and method of underground water supply facility survey/probe and problem being occurred during survey/probe procedure and also show the functions of each sub-systems composing underground water supply facility management system.

It is an urgent issue to manage and reduce non-point pollution sources for improving the water quality of stream and lakes in rural areas. In this study, in order to reduce non-point pollution sources in rural area, Gabion mattresses was proposed to provide protection of riverbanks with anaerobic and aerobic area. The utilization of this was assessed by lab scale model test and pilot plant test. After filling the inside of the gabion mattresses with aggregate, the filtration zone under anaerobic and aerobic conditions was formed to treat the contaminants. In addition, vegetation was deposited on the surfae of the gabion to prevent the inflow of soil and to promote purification by the plant. COD and nitrogen content (T-N, $NH_4{^+}$, -N, $NO_3{^-}N$) were monitored in model and field tests. The lab scale model test showed removal efficiency of 17% of TCOD, 35% of SCOD, 14% of TN, 62% of $NH_4{^+}$, -N, and 33% of $NO_3{^-}$ N. Also, pilot plant test showed removal efficiency of 24% of TCOD, 29% of SCOD, 47% of TN, 50% of $NH_4{^+}-N$, 33% of $NO_3{^-}$, N and 29% of TP.

The war that broke out on October 7, 2023 is prolonging and expanding into the Middle East. Although the damage from war is increasing, humanitarian aid to the Gaza Strip has been halted due to UNRWA's deviant actions. Powerful countries have suspended support, and the UN is appealing for support for the Gaza Strip. All damage is borne by civilians in the Gaza Strip, especially women, children, and the elderly. Israel has selected an evacuation zone and evacuation route in the Gaza Strip and established a humanitarian aid route in the border area. However, Hamas's resistance in underground tunnels, using civilian-dense areas and civilian facilities such as hospitals and schools as shields, further amplified civilian casualties. This Israel-Hamas war requires the international community to approach it from a human security perspective. We must strengthen the UN's functions and roles to ensure that humanitarian supplies reach the field and humanitarian intervention forces ensure human dignity and basic rights. We must restore the credibility of the UN's role through the Israel-Hamas war. In addition, Korea should urge the introduction of humanitarian aid and goods, and provide humanitarian goods such as daily necessities and medicine. We must also prepare for deployment as a member of the UN peacekeeping force in the future. These activities will help Korea develop into a model country that fulfills its role as a 'global pivotal nation' and will have a virtuous cycle of international support in the event of a future crisis on the Korean Peninsula.

Background: Bronchial hyperresponsiveness and abnormal response such as a loss of distensibility are pathophysiologic characteristics if bronchial asthma. The only means of direct in vivo measurement of airway size had been a tantalium bronchography, until high-resolution computed tomography(HRCT) enabled to measure noninvasively two dimensional airway area more accurately and reliably. Method: To investigate airway area responses to bronchial provocation with methacholine and evaluate the major sites of bronchial constriction in patients with bronchial asthma. We examined HRCT scans in five patients with bronchial asthma who had significant bronchoconstriction(20% or more decrease in $FEV_1$) using CT scanner(5,000T CT, Shimadzu Co, Japan) before and in 3~5 min. after methacholine inhalation. Airways which were matched by parenchymal anatomic landmarks in each patient before and after methacholine inhalation were measured using film scanner(TZ-3X scanner; Truvel Co. Chatsworth CA, USA) and a semiautomated region growing method. Results: 1) We identified 9 to 12 airways in each patient which were matched by parenchymal anatomic landmarks before and after methacholine inhalation. 2) Airway responses to methacholine are quite different even in a patient. 3) The constriction of small airways(average diameter <2 mm; area < $3.14mm^2$) was 48.7%(8.3; SEM, n=43), being more prominant than that of large airways(average diameter >2 mm; area > $3.14mm^2$), 53.8% (4.4;SEM, n=10), but not significantly different(p>0.05). 4) There was no significant difference in the degree of constriction between upper(44.3% +5.8; mean + SEM, n=30) and lower lung regions(56.7% +4.5, n=23). Conclusions: Thus airway responses to methacholine bronchoprovocation is quite variable in a patient with bronchial asthma and has no typical pattern in patients with bronchial asthma.
