하구둑은 해수의 역류에 의한 염수침입을 방지하고 유역에 필요한 담수를 확보하기위하여 건설되며, 하구둑에 의하여 하천의 하구에 담수호가 생성된다. 하구담수호에 의해 기존에 염해로 취수할 수 없었던 하천구간에서의 취수가 가능하게 되며, 하구담수호를 일정한 수위로 관리함으로써 상당량의 농업용수를 확보할 수 있다. 이와 관련하여 하구담수호에 의하여 확보되는 수자원량에 대해 설계 당시의 분석 자료들이 있기는 하지만, 대부분 연 총량의 형태로 나타나 있으며, 수리권과 관련하여 하구둑에 의하여 추가적으로 확보되는 수리권 가용수량이 얼마인지에 대한 분석은 거의 없다. 그것은 하구둑의 방류량이 댐의 방류량과는 달라서 조석의 영향을 매우 크게 받기 때문에 단순한 물수지 분석으로 이를 모의하기 힘들기 때문이다. 게다가 1일 2회의 조석이 발생하므로 1일단위의 물수지 분석은 어려운 현실이다. 그럼에도 불구하고 하구둑에서 많은 양의 농업용수 취수가 이루어지고 있다. 과연 얼마정도의 양이 수리권으로서의 역할을 할 수 있는지 모르고 임의적인 허가가 계속 부여될 경우, 갈수 시 용수공급의 안정성을 확보할 수 없게 될 것이다. 따라서 안정적인 용수의 공급을 위한 적절한 수리권 가용수량에 대한 추정 필요하다. 이에 본 연구에서는 영산강하구둑의 실시간 운영을 위하여 고 등(2004)이 개발한 "영산강하구 둑 물관리 프로그램"의 기본적인 조위의 예측과 배수갑문의 방류량 산정기법 등과 수자원장기종 합계획(2006) 수립 시에 사용된 장기간의 일자연유량을 이용하여 하구둑의 수리권 가용수량 추정 모형을 개발하고, 이를 영산강 하구둑에 의해 생성된 영산호에 적용함으로써 영산호에 의해 증가되는 수리권 가용수량에 대해 고찰하여 보았다., 그리고 T-P $77.7{\sim}96.6%$(평균 94.3%)로 산정되었다. 이러한 결과는 대청호로 유입하는 유기물과 영양염류 연간 부하량의 80% 이상이 강우-유출과 함께 유입하는 것을 의미하며, 저수지 수질관리를 위해서는 유역차원의 비점오염원 관리가 시급함을 시사한다.하기 위해, 수렴흐름 추적자시험에 의한 종분산지수와 시험대수층의 평균선형유속을 이용하여 종분산계수를 구하였다. 현장에서 수행된 양수시험에 의한 평균선형유속 22.44 m/day와 평균 종분산지수 0.4155 m를 적용하여 산정된 종분산계수는 $9.32\;m^2/day$이었다. 따라서, 시험부지 내 충적층에서 일정한 양수율$(2,500\;m^3/day)$로 지하수를 개발할 시에 양수정 주변지역으로 유입되는 염소이온의 확산면적은 1일 $9.32\;m^2$ 정도일 것으로 나타났다.적인 $OH{\cdot}$ 의 생성은 ascorbate가 조직손상에 관여할 가능성을 시사하였다.었다. 정확한 예측치를 얻기 위하여 불균질 조직이 조사야에 포함되는 경우 보정이 요구되며, 골반의 경우 골 조직의 보정이 중요한 요인임을 알 수 있었다. 이를 위하여 불균질 조직에 대한 정확한 정보가 요구되며, 이는 CT 영상을 이용하는 것이 크게 도움이 되리라 생각된다.전시 슬러지층과 상등액의 온도차를 측정하여 대사열량의 발생량을 측정하고 슬러지의 활성을 측정할 수 있는 방법을 개발하였다.enin과 Rhaponticin의 작용(作用)에 의(依)한 것이며, 이는 한의학(韓醫學) 방제(方劑) 원리(原理)인 군신좌사(君臣佐使) 이론(理論)에서 군약(君藥)이 주증(主症)에 주(

Since the first 12 ones were designated in 1969, 228 places have been designated as tourism sites, and about 70 percent of them were designated before the 2000s. It shows that changes in most of tourism sites are needed in terms of physical, functional and environmental aspects. However, there are still not enough academic progress and policy consideration regarding the decline of tourism sites and the regeneration of them. This study aims to find the causes of decline and the factors to activate in tourism sites, to draw important conditions to recover the attractiveness of tourism sites in decline from the comprehensive analysis of causes and factors, and to apply the conditions to a real case in severely declining stage. According to the findings, the conditions for recovery could be restructured into four categories: 'The upgrade of hardware such as facilities in tourism site', 'the development of software such as contents and programs', 'the reinforcement of local capacity and institutional grounds' and 'the expansion of functions and the building of networks with various external stakeholders such as expert groups, related enterprises, talented individuals and so forth.

The traditional laws of Korea have undergone various stages of development over time. This includes the voluntary standards of the clean society. Korea's traditional legal systems, ranging from those of the Goryeo(高麗) to those of the Republic of Korea, have taken Confucian Phiosophy as their major ideological bases. At the center of these Confucian ideals, particularly in regards to pre-Qin Confucian Philosophy(先秦儒家思想) from where these ideals originated, lie the core ideals which emphasize the responsibility of each individual regardless of the social status(正名), the needs for a democracy in which people are empower and guide the state(民本), the importance of reigning with benevolence, moral excellence, and rite (仁義), and the differential love centered on kinship and humanity(親親愛人). These were the ideas as set forth by Confucius(孔子), Mencius(孟子) and Xun Zi(荀子). The current laws of Korea, especially in regards to the Constitution and the Civil and Criminal Laws, include a number of provisions that contain the Confucian Ideas of Law. The Constitution, in particular, which is also supported by the judgement of the Constitution Court, reflects several core Confucian ideals including filial duty (孝) and respect for ascendants and the traditional culture. The Court also suggested the two important standards of the constitutional legitimacy of the Traditional Culture. One is 'Age Compatibility (時代 適合性)', the other is 'Manifested Universally Validity(現在的 普遍妥當性)'. So we have burdened with the reestablishment of the Universal Ethics of the Confucian Ideology.

This paper examines the lava tubes designated as a natural monument in Jeju Island, and then makes the several suggestions for conserving and managing them. The cave entrances should be scientifically and strictly managed to prevent the deterioration, and to preserve the interior ecosystem, of the lava tubes. The land use and vegetation of the ground surface over the lava tubes should be also systematically managed; the destroyed sand dunes must be recovered for the development of speleothem in the lava tubes, and the plants with deep roots must be removed for the prevention of ceiling collapse. The provincial authorities should manage the ground surface over the lava tubes as a public land to remove the factors threatening the stability of the lava tubes. Since the roads crossing the ground surface are likely to cause the collapse of the lava tubes, new roads bypassing the caves need to be constructed, and warning signs should be also installed at the traverse points. A monitoring system on the cultural properties protection area over the lava tubes could be effectively established by encouraging residents to participate the conservation program of lava tubes. Since the falling blocks from ceilings have been usually observed in the lava tubes, it is urgent to examine their stability. In particular, the dangerous sections must be continuously monitored for taking a quick measure against the collapse. The air environments of lava tubes need to be scientifically analyzed based upon the long-term observations. The lighting equipments must be improved to minimize the green pollution in the lava tubes open to the public. The numbers of visitors should be also controlled to prevent the destruction and contamination of lava tubes caused by a large number of visitors.

This paper presented a method to build a predictable smart ammunition logistics system using the 4th industrial technology for ammunition logistics, which is the core functions in the field of defense and logistics. We have analyzed the current level of ammunition logistics with various perspectives such as domestic and overseas logistics policies, technology trends, ammunition logistics characteristics, the smart logistics certification measures by Ministry of Land, Infrastructure and Transport. As a result it is considered that the current ammunition logistics needs needs improvement. To improve this, we presented a direction based on the implications derived after analyzing various ongoing programs such as wired/wireless-based automation, smart ammunition depots, and logistics innovation of the army, navy, and air force that can be applied to the ammunition logistics. In order to implement a data-based smart ammunition logistics management system that can achieve innovation and efficiency of total life cycle while meeting changes in the battlefield environment, we presented 4 objectives such as "automation and modernization of field work", "3D-based storage management & improvement of issuing at war," and "data management for prediction-oriented ammunition management". it is expected that there will be benefits such as improvement of operational continuity, guarantee of ammunition reliability, budget reduction, improvement of inefficiencies such as delay, waiting, and double work, and reduction of accidents.

The laws and regulations governing the operation of government committees in Korea provide for a system called exclusion. Exclusion is a system that excludes a member of a committee from deliberating or voting on a matter or agenda without having to go through a special procedure before deliberating or voting on the matter or agenda. This is because exclusion of a member from deliberation and voting is not only essential for the protection of the interests of the parties to the issue or matter and the peaceful resolution of disputes, but is also a very important value for the trust in the fairness of the process. However, in practice, it is not easy to determine that a member who has a reason for disqualification is naturally incapable of executing the duties of the matter or agenda just because he or she has a reason for disqualification. Prior to the overhaul of the disqualification rules for committee members in the statutes, it is necessary to eliminate the disqualification rules that are virtually dead in advance or to revise the rules that are difficult to determine without interpretation, contrary to the intention of the disqualification rules that are codified in the law. Therefore, this study analyzed the disqualification rules of nine committees in the domestic statutes (laws and enforcement regulations) and categorized the disqualification rules. We hope to contribute to the preparation of future legislative proposals to improve the rules on the exclusion of commissioner.

Recently, the intensity and frequency of floods has increasing worldwide, and flood disasters have become a big problem. Flood disasters, which account for the largest portion of disasters, are floods accompanied by typhoons and localized heavy rainfall. As a result, they cause damage of levee overtopping, in which the water level of a river rises to the levee crown. Therefore, countermeasures are essential and necessary because of the damage to the facility itself as well as to life and other property. The damage magnitude depends on the collapse of the levee. A levee that is difficult to collapse will reduce the discharge inland significantly. Accordingly, the protection of the inland slope, where the collapse of the levee is initiated, is one of the most important countermeasures In this study, revetments with various porosity and forms were suggested and hydraulic experiments were carried out for each type. The hydraulic experiments showed that the stability of a revetment in an inland slope is strongly correlated with the weight per unit area of the revetment. The relationship between the critical velocity, which is the velocity at the moment of leaving the revetment, and the weight per unit area was derived. Through this study, by applying the nature friendly revetment, which has not yet been applied to Korea, it is expected that life and property damage caused by levee overtopping during flooding can be reduced, and a nature friendly river space can be constructed.

This study was carried out to review the guidelines being used by law and national policy concerned on river environments management and suggest the applicability of newly developed river environment assessment system. In the current legal system, the national river environment management system is insufficient in securing an independent status in the legal institutional system which is separated to the Ministry of Land, Transport and Infrastructure and the Ministry of Environment. And the river environment assessment system of the national standard, which is a core matter, has not been established yet. In particular, there is a lack of integrated approach between the upper and lower plan or related plans on water resources, water quality, river environment and aquatic ecosystem management. In addition, the consistency and effectiveness as the process of planning and design according to the current status and comprehensive analysis and evaluation of the river environment were not secured either. To integrate national river environment management system and improve efficiency, I proposed the establishment of hierarchy and connection between national river plans, and the adoption and application of developed assessment system based on characteristics of river environment in Korea. Finally, I proposed the separated application with dividing the developed assessment system including the naturalness of river environment and suitability of water friendly activity into both assessment method for management plan of water resources of river basins & basic river plan respectively.

This study analyzed the trends of broadcaster licensing policy during 1990-2001 in Korea. It is to seek the answers about how the examination standards and procedures applied to broadcaster licensing has been changed for the last decade. For the purpose this study inquired six cases such as private broadcasting licence (1990 October), cable TV program provider licences(1993 July), cable TV system operator licences(1994 January), private local broadcaster licences(1994 July), satellite broadcaster licence(2000 December) and cable TV home shopping channel licences(2001 March). It examined the degree of specification and measurement of the standards based upon the government white paper; average points per item, average points per quantitative item, and average points per qualitative item etc. The government hadn't opened the standards and procedures how it licensed broadcasters until 1990 and the uncertain attitude brought distrust on the government broadcasting policy. The first white paper about broadcaster licensing was made in 1994 after cable TV broadcaster licensing was finished. The results indicated that Korean broadcasting licensing policy rapidly developed in the dimension of transparency from 'a secret room policy' to 'a sunshine policy' for the last decade. But it still needs improvement in the dimension of fairness of examination. Now one of the main distrust is the ratio that the one of qualitative examination standards are much more than the qualitative one.

The aim of this study was to investigate whether the schools and local governments were aware of the creation and operation of school forests. A survey was conducted of 45 teachers of schools selected as having the best practices in the school forest and 153 local government officials within the district where the school forests were built. The school teachers attributed the necessity to create school forests to the importance of beautifying the environment. The results showed that the area in which the school forest was created, the school environment after the school forest was created, and use of the school forest were generally satisfactory, but maintenance of the school forest was not somewhat unsatisfactory. Additionally, the results indicated that continuous maintenance was necessary for the effective use of the school forest, and there was a great need for professional personnel to conduct the maintenance program. Furthermore, local government officials recognized that beautification of the school environment was the best effect of creating the school forests. They also realized a great need for local government's support of a maintenance program and its cooperation with related ministries and agencies to create and operate the school forest. Thus, it is crucial to devise measures for maintenance and to establish a system by which schools and local governments can work closely to promote the creation and operation of these school forests.
