This thesis is to research the before and after changes of physical configurations, blood components and physical strength for normal and geriatric diseased senior citizens at the end of 24 week of combined exercises constructed of aerobic and muscular strength training to create most suitable and effective complex exercise program for geriatric diseased patients. For this experiment 20 normal and 20 geriatric diseased patients in the age of 65 residing in "K" city were selected to carry out the 24 weeks of combined exercises in regularly. The result of the research showed that geriatric patients increased significantly in everything, but normal group showed significant change in only WHR. There was a slight improvement in the blood components for the average participants but it only differed slightly from the diseased participants so there were no major changes reflecting the outcomes from both before and after. After concluding the program both groups displayed positive improvements in stamina but no significant alterations in physical strength., agility, muscle endurance and balance. The positive factors for each groups could be that the norms were able to maintain their health and enhancement in stamina and diseased were able to prevent their condition from worsening. Additionally, over 50 percent of all senior citizens have one or more geriatric diseases but the participation of any physical activity is in the decrease. Henceforth, this is a field that still needs a lot of work and combined exercise programs should be created and followed through so it may enhance in the improvement of health and quality of life as well.

The purposes of this study were to identify the economic impacts of hosting a marine leisure event and thus provide fundamental information that helps maximize the economic value of the event. In order to accomplish such purposes, this study employed both an economic impact analysis(EIA) using regional input output model and a benefit and cost ratio analysis(BCR). In specific, this study utilized a survey method with a total of 300 event visitors and 70 foreign players and thus collected expenditure data from 110 valid out of town visitors and 58 foreign players. In addition, investment expenditure data were collected from the host city official. Accordingly, EIA and BCR indicated following findings. First, the total direct impact from both visitors and players was 387 million Won and this direct impact resulted in output multiplier effect(OME) of 591 million Won, value added multiplier effect(VAME) of 306 million Won and income multiplier effect(IME) of 252 million Won. Second, the host city's investment expenditure created OME, VAME and IME of 825, 432 and 366 million Won, respectively. In conclusion, these findings suggest that in order to effectively boost potential economic benefits, more marketing efforts development policies should be implemented for increasing the number of out of town visitors and the amount of spendings from them.

Recently, the number of occurrences of inundation and the severity of flood damage has increased rapidly as the frequency of localized heavy rainfall and the ratio of impervious area increased in urban areas. Most local governments focus on employing structural measures (e.g., the construction of detention reservoirs/pump stations, rehabilitation of drainage and sewer pipes) to prevent urban inundation. On the other hand, the effectiveness of implementing such structural measures is being dimished because there are already many inundation prevention facilities. The limitation of structural measures can be overcoming by employing non-structure measures, such as flood alerts and the operation of drainage facilities. This study suggests the pump operation rule (i.e., suggesting pump stop level) for a new detention reservoir operating method, which triggers the operation of a pump based on the water level at the monitoring node in urban drainage system. In the new reservoir operation, a total of 48 rainfall events are generated by the Huff distribution for determining the proper pump stop level. First, the generated rainfall events are distributed as frequencies, quartiles, and durations. The averaged system resilience value was determined to range from 1.2 m to 1.5 m is based on the rainfall-runoff simulation with rainfall generated by the Huff distribution. In this range, 1.2 m was identified considering the safety factor of 1.25 by the Standard on sewer facilities in 2011.

To ensure that Korea continues to grow, past governments have been consistent in following a policy of advancing into Russia, Mongolia, and Eurasia. The northern economy can expect to achieve synergistic growth because its economic structure complements that of Korea, which has high energy demand and industrial development. There is also an opportunity to accelerate the growth of the China-Russia-Mongolia economic corridor, which is based on Russia's Look East Policy, China's One Belt One Road, and the Mongolian Steppe Road initiative. The Korean government is pursuing a New Northern Policy to achieve the goal of economic cooperation and peace building with other nations, including North Korea; this policy succeeds the Northern Policy pursued by the previous government. As international economic cooperation requires transportation infrastructure, the demand for shipping, which offers more advantages than road and rail transportation, will increase; thus, it is necessary to prepare for it. Korea's port cities, which have a port that serves as the nodal point for maritime transportation, need to prepare for the New Northern Policy. In this paper, the long-term development of Seosan-Daesan port in the was planned and the North Korea's opening-op plan was considered in accordance with the New Northern Policy. Because international cooperation between the government and the provincial cities is required, cooperation with the Port Authority is needed, along with the proactive attitude of Seosan City, Chungcheongnam-do. The Seosan-Daesan port, which is the center of the liquid energy cargo center, can become the base of the New Northern Policy Region; further, the port can be an opportunity to establish its position as a peaceful economic hub on the west coast of Korea.

The purpose of this study is to analyze and diagnose the actual state of extinction risk in rural villages by analyzing time series population characteristics and extinction risk index of rural villages(Haengjeong-ri). As a research method, a time series analysis was performed on the 'population over 65' and the 'female population aged 20 to 39' related to the local extinction index. In addition, the disappearance of Haengjeong-ri village was analyzed using the existing local extinction index. For the study, Haengjeong-ri village-level GIS spatial data was constructed, and population attribute data in 2010, 2015, and 2020 were constructed. In order to derive implications, the change of the 'high risk of extinction 'village in the 2020 local extinction index, the distribution of the population of 'high risk of extinction' villages by three years, the population analysis of 'high risk of extinction' villages continuously from 2010 to 2020, and 'high risk of extinction' An analysis of the increase and decrease of the population of the village and the change of the local extinction index of Haengjeong-ri, where the city, county, and towns are located were analyzed. As a result of the analysis of this study, it was found that the number of villages with an aging of more than 50% increased by 2 to 3 times over 10 years. As a result of the analysis of the local extinction index, in 2010, the southwestern and central regions of South Chungcheongnam-do were high-risk extinction areas, but in 2020, all cities except Cheonan and Asan were converted to high risk extinction areas. Research has shown that Chungnam is facing a serious aging and village extinction crisis, and since the disappearance of villages gradually spreads, an initial response policy is needed. This result will be the same not only in Chungcheongnam-do but also in other rural villages. Therefore, in the case of rural villages, it is necessary to analyze and diagnose the Haengjeong-ri village unit, not the Eup-Myeon unit, and a response policy through diagnosis must be prepared urgently.

For high school students in Jeonbuk, this study aims to identify the problems caused by outflow of local youth population and their preference factors to enter university in Seoul-metropolitan area, and to draw out the direction of local human resources program, through questionnaire investigation and focused group interview. The main findings are as follows: First, 68.8% of high school students, especially the top grade students prefer to enter university in metropolitan area. The metropolitan cultural characteristics, such as reputation of universities and ranking, openness and anonymity, and urban infrastructure attract students. Second, there is a close relationship between the individual background, growth area - enrollment area - employment area, and the location dependency without return migration is very strong. Third, local human resources program was evaluated as a meaningful activity for high school students, in order to understand the further education and career, and have an interest in local universities. Therefore, it is necessary to discover industries consistent with local identity, create networks, develop and implement programs considering the actual educational conditions. The gender-free program, supplement program for the integrated curriculum, and contents that to supplement science subjects should be developed. Additionally, this issue could be resolved expanding the perspective of balanced national development and improve the local environment to enhance the urban attraction points.

1970년대 이후 급속한 경제성장과 함께 도시화와 산업구조의 변화로 인간 활동과 밀접한 관계를 맺고 있는 수환경은 크게 훼손되어 왔다. 특히 인간 활동으로 인한 대량 생산과 소비는 하천의 자정작용을 초과하는 오염물질을 배출하고 오염된 하천은 본래 기능을 상실하였으며 각종 생활 오·폐수의 배수구로서의 역할이 부여되어 대부분 복개되기에 이르렀다. 이처럼 현재 우리나라의 하천은 고유의 기능인 용수원으로의 기능과 도시민의 휴식 및 친수공간으로서의 기능을 상실하였으며 중소하천의 건천화에 따른 하천 유지유량의 부족은 하천을 중심으로한 각종 용수의 부족, 수질 오염의 증가, 수변환경 친수기능 상실 등의 문제를 초래하고 있다. 중소하천의 건천화현상은 2000년대 이후 계속 증가, 진행되어 소하천뿐만 아니라 지방하천도 이미 메마르고 있는 상태이며 이로 인한 2차적 비용증가 등 경제적인 측면의 손실도 매년 심해지고 있어 건천화에 대한 원인 규명과 방지책에 대한 연구가 시급한 실정이다. 특히 새만금유역은 농업용수 사용이 많은 유역의 특성상 하천의 건천화 문제가 지적되었으나, 대부분 새만금유역의 용수이용체계 등에 연구가 추진되어 주로 농업용수 이용실태와 수질측정을 위주로 하고 있으며, 건천화의 실태와 원인, 그리고 건천화로 인한 물환경의 영향 등에 대해 조사된 바가 없다. 따라서 본 연구는 만경강유역 하천에 대하여 대조하천, 도시하천, 준도시하천, 농업하천으로 대표지점을 선정하여 현장조사와 유역모델링을 통해 건천화의 원인별 기여율을 파악하였고, 만경강유역의 건천화 규모를 추정하였다. 건천화 원인을 평가하기 위해 유역 내 인위적인 물이용이 없는 상태인 기준유량(자연유량)을 산정하였고, 댐 및 방류량의 영향, 하수처리수 유입에 의한 영향, 수자원이용에 의한 영향, 수리구조물(수자원이용)에 의한 영향의 조건을 고려하였으며 건천화 평가지수를 활용하여 대상하천 소유역의 건천화 현황을 파악하였다. 또한 분석된 결과를 토대로 만경강유역의 토지이용도를 고려하여 만경강유역의 건천화 규모를 추정하였다. 분석결과, 수리구조물(수자원이용)에 의한 영향이 25.5%, 수자원이용에 의한 영향이 13.9%, 방류량에 의한 영향이 12.3%, 하수처리수 유입에 의한 영향이 6.54%로 나타났으며, 수리구조물(수자원 이용)에 의한 영향이 가장 크게 평가되었고, 하수처리수 유입에 의한 영향이 가장 작은 것으로 평가되었다. 이러한 연구결과는 향후 하천의 건천화현상에 대한 원인을 규명하고 방지하기 위한 대책 수립에 필요한 기초자료로 활용이 가능할 것으로 판단된다.

The city planning of a local government is a continuous process that does not end with the creation of a plan but proceeds through decision-making, monitoring and evaluation phases. As a new city planning is changed and confirmed, there is a chance to construct a large scale road that is connected with an under constructed road. In this case, the expansion of the width and length of road, the addition of bridges or tunnels, and the change of the size and location of interchanges lead to many changes on road design and construction. In the past, the consignment contracts for a road construction have been made in limited numbers and for limited civil works. Now, it is growing in numbers and is making for large scale multi-works. However, the standard process and guidelines for the consignment contracts have not been suggested yet, so there is difficulty in performing the consigned road construction effectively. In this paper, the important factors for the consignment contracts are determined by construction document reviews and expert interviews. Based on these results, a standard process for the consigned contracts and a guideline for agreeing on construction cost are suggested. The costs that should be paid by a consignor are also defined.

This study generated regression models to quantify storage and annual uptake of carbon from five native landscape tree species through a direct harvesting method, and established essential information to estimate carbon reduction effects from urban greenspaces. Tree species for the study included the Chionanthus retusus, Prunus armeniaca, Abies holophylla, Cornus officinalis, and Taxus cuspidata, which are usually planted in cities of middle Korea, but for which no information on carbon reduction is available. Ten tree individuals for each species were sampled reflecting various stem diameter sizes at a given interval. The study measured biomass for each part including the roots of sample trees to compute total carbon storage per tree. The annual carbon uptake per tree was quantified by analyzing the radial growth rates of stem samples at breast height or ground level. Regression models were developed using diameter at breast height (dbh) or ground level (dg) as an independent variable to easily estimate storage and annual uptake of carbon per tree for each species. All the regression models showed high fitness with $r^2$ values of 0.92~0.99. Storage and annual uptake of carbon from a tree with dbh of 10 cm were greatest with C. retusus (20.0 kg and 5.9 kg/yr, respectively), followed by P. armeniaca (17.5 kg and 4.5 kg/yr) and A. holophylla (13.2kg and 1.8 kg/yr) in order. A C. officinalis tree and T. cuspidata tree with dg of 10 cm stored 9.3 and 6.3 kg of carbon and annually sequestered 3.2 and 0.6 kg, respectively. The above-mentioned carbon storage equaled the amount of carbon emitted from gasoline consumption of about 23~35 L for C. retusus, P. armeniaca, and A. holophylla, and 11~16 L for C. officinalis and T. cuspidata. A tree with the diameter size of 10 cm annually offset carbon emissions from gasoline use of about 6~10 L for C. retusus, P. armeniaca, and C. officinalis, and 1~3 L for A. holophylla and T. cuspidata. The study breaks new ground to easily quantify biomass and carbon reduction for the tree species by overcoming difficulties in direct cutting and root digging of urban landscape trees.

This paper develops the argument that the 'Healthy Cities Approach' extends beyond the boundaries of officially designated Healthy Cities and suggests that signs of it are evident much more widely in efforts to promote health in the United Kingdom and in national policy. It draws on examples from Leeds, a major city in the north of England. In particular, it suggests that efforts to improve population health need to focus on the wider determinants and that this requires a collaborative response involving a range of different sectors and the participation of the community. Inequality is recognised as a major issue and the need to identify areas of deprivation and direct resources towards these is emphasised. Childhood poverty is referred to and the importance of breaking cycles of deprivation. The role of the school is seen as important in contributing to health generally and the compatibility between Healthy Cities and Health Promoting Schools is noted. Not only can Health Promoting Schools improve the health of young people themselves they can also develop the skills, awareness and motivation to improve the health of the community. Using child pedestrian injury as an example, the paper argues that problems and their cause should not be conceived narrowly. The Healthy Cities movement has taught us that the response, if it is to be effective, should focus on the wider determinants and be adapted to local circumstances. Instead of simply attempting to change behaviour through traditional health education we need to ensure that the environment is healthy in itself and supports healthy behaviour. To achieve this we need to develop awareness, skills and motivation among policy makers, professionals and the community. The 'New Health' education is proposed as a term to distinguish the type of health education which addresses these issues from more traditional forms.
