본 문헌고찰은 지역사회의 트랜드의 변화를 IT도입의 배경과 거시적 행정의 변화과정을 통하여 살펴봄으로써 지역사회의 역동성의 나아갈 방향에 관하여 논의하고자 한다. 본 연구의 문헌고찰은 IT도입은 우리들의 지역사회에 관한 어떠한 대안을 내놓고 있는가? 우리는 어떠한 관점으로 이를 바라보아야 할 것인가?에 관하여 Managing IT and e-Government：the Korean Case, Moon Sinyong(2009)의 관점을 중심으로 하여 살펴보았다. 현대는 내부 및 외부적(internal & external) 개혁이 모두 필요한 시대이다. 따라서 현대의 지역사회 소비자는 단순소비자가 아니며 생산과 소비에 기여하는 프로슈머들이다. 이는 사회적비용(social cost)을 재배치하는 것이며 지역사회나 국가적 차원에서도 적극 도입되어야할 부분으로 평가받고 있는 부분이며 현대사회는 분권화(decentralization)가 중요한 사회이기도 하다. 이것은 과거의 표준화 전문화 중앙집권화에서 보다 발달된 형태로 시대의 욕구에 부응하는 것이라고 할 수 있다. 이제 현대사회는 탈집중화 탈대중화 되는 시기로써 더욱 개별화된 서비스가 늘어갈 것이며, 위탁의 효율성이 극대화 될 것으로 보인다. 그러므로 이러한 시대적 변화에 있어서 어떠한 점이 고려되어야 하며, 지역사회의 개발과 통합 및 관리적 차원에서는 어떠한 점에 관한 논의가 선행되어 필요할 것인가에 관한 보다 구체적인 지역사회 차원의 합의도출이 필요하리라 보여진다. 이와 같이 지역사회의 역동성은 우리사회의 변화과정을 설명하고 있는 것이며, 그것은 우리 자신에게 달려있기도 하다. 따라서 현대사회의 지역의 분권화와 정보화의 개념 속에서 상기와 같은 자원들이 어떻게 수렴되고 발전해 나갈 것인가는 바로 우리 지역사회 커뮤니티의 성숙도를 의미하기도 할 것이라 보여진다. 한 시점에서 우리나라의 지방분권의 출범이, 지역사회의 고유한 비젼을 통한 변모과정과 발전에 있어 행정의 변화과정과 시대적 조류 그리고 IT도입에 관한 문제에 관한 논의는 반드시 필요하며 그 안에 시사점이 있다고 할 수 있을 것이다. 우리는 정보화 사회의 한 가운데 있다. 본 연구에서는 이러한 과정에서 지역사회가 고려해야 할 사항에 관하여 개략적으로 다루어보았다. 따라서 향후 에는 다양한 후속연구를 통하여 이러한 시대적 역동성이 우리 지역사회에서 어떠한 모습으로 역동성을 지니고 발전하고 있는지에 관한 보다 세밀한 연구가 지속되어야 할 것이다.

PURPOSES : Lots of criticism such as over/duplication investment, inconsistency of the policies among local governments and national plans etc. has been aroused due to the policy of supply-driven construction for transportation facilities. Recently, according to the environmental-friendly transportation policy, the investment of railroad has been expanded gradually, however the duplication with existing road facility makes it difficult to construct railroad. Thus it is necessary to evaluate the interrelationship between new project and existing facilities in the planning stage. However the method and the criteria for analyzing the duplication and over-investment of projects are not established in the manual, thus the feasibility of these projects are carried out from the economic point of view. METHODS: First, It reviewed about interrelationship criteria(domestic, overseas) and proposed implications and this study directions. Next, It developed the methods of evaluating independency, competitiveness and complementarity. RESULTS : In this study, the methods of evaluating independency, competitiveness and complementarity etc. are suggested to analyze the interrelationship between transportation facilities. The case study was carried out to examine the applicability of the methods. CONCLUSIONS: The methods raise rationality of decision-making compared to existing one. In the future, these methods are introduced into the manual of pre-feasibility study and feasibility study, more efficient decision-making and investment are expected.

PURPOSES : This study aims to suggest the optimal spacing between speed humps which is placed at traffic calming areas including pedestrian priority zones, school zones, and residential areas. METHODS: The study measured the operating speed of vehicles passing through two successive humps by using laser gun in 0.2 seconds interval, and analysed the basic statistical characteristics of speeds data to have an insight on the relationship between spacing and speed. Assumption was made to derive the maximum spacing within which two successive humps influence each other. RESULTS: The statistically significant model explaining the relationship between spacing and 85th percentile speed of vehicles was derived as well as the maximum spacing maintained in order to take the benefits of successive installation of humps. CONCLUSIONS: Spacing of 20 meters was suggested to achieve the widely accepted target speed of 30 km/h in traffic calming zone, and spacing of 70 meters was suggested as a maximum spacing. The comparison across the studies were made and empirical reasoning the difference of results between studies was discussed as well as the future studies.

PURPOSES: The purpose of this study is to develop a method for distribution between superelevation and side friction factor by increasing design speed. METHODS: First of all, a method for distribution between superelevation and side friction factor and a theory for the functional formula of side friction factor in compliance with horizontal radius applied in South Korea and the United States are considered. Especially, design speed of 140km/h and numerical value of design elements are applied to the theory for the functional formula of side friction factor in AASHTO's methods. Also, the anxiety EEG upon running speed is measured to reflect ergonomic characteristics through field experiments at seven curve sections of the West Coast Freeway, and this data is applied to graph for the functional formula of side friction factor. RESULTS : Matching side friction factor against the anxiety EEG, the results that a critical points of driver's anxiety EEG sharply increase locate under existing parabola are figured out. CONCLUSIONS : Therefore, we could get a new type of the functional formula that driver's driving comfortability is guaranteed if the existing the functional formula of side friction factor goes down under boundary of the critical points of the anxiety EEG.

In an effort to find the optimum porous of Taewoo through the mathematical model 2 - dimensional tank water experiment among the approached to a problem related to ocean engineering, this study analyzed the porosity by dividing it into 9 cases. As the wave penetrates through the longitudinal porous of the Taewoo model, it was found that there is a wave energy loss because of the phenomenon of the separation of the porous due to the eddy. Looking into the general tendency based on the wave-height meter (probe) data, it was found that the shorter wavelength and higher frequency area, the more reflection coefficients increased, but in contrast, the longer wavelength and lower frequency area, the transmission coefficients showed the increasing trend and energy dissipation was in a similar way with reflection coefficients. In addition, it was found that the bigger the porosity was, the narrower distribution range of reflection coefficients was, and the more its average value decreased. On the other hand the transmission coefficients in direct opposition to reflection was found to show the wider range and the more gradual increase in the average value as porosity was the bigger around the average value. In contrast, energy dissipation rate was found to increase linearly as porosity increased the more around the porosity of 0.2518 but it decreased gradually around the peak point. Through the above results, it is judged that the porous of optimum in the longitudinal direction of the Taewoo model perforated plate was about 2.6cm because it was found that the porosity which produced the lowest reflection and transmission coefficient and the highest energy dissipation. As a result of comparing this to the case where there was no porosity at all, it showed the function of wave absorbing about 31.60%.

In addition, it was verified on the death rate as 99.9% on the scale protrusion of "Aeromonas hydrophila" as well as E. coli, especially, under extreme conditions more than 100 million pathogenic bacterium in the aqua pet tank, the ornamental fish had to act in a safe and healthy environment at over 98% death rate within 48 hours. It has been proven to give no affect on aerobic bacteria that exist in the filter or soil because there was no residual toxicity in the water tank. As the results, it will help to develop and apply on the sterilization device in other industries as well as aquarium organisms due to adopted energy-saving algorithm and reliability in use.

본 연구에서는 계면활성제 분석법의 개발을 위하여 High performance liquid chromatography-evaporative light scattering detection(HPLC-ELSD) 기기를 이용하여 음이온 및 비이온 계면활성제 중 다소비 계면활성제인 Alkyl polyglucoside(APG)와 Alpha olefin sulfonate(AOS)를 분석하였다. 실험 결과 APG와 AOS 모두 직선성의 상관관계 계수(R2)가 0.99 이상으로 직선성이 양호하였으며, 검출한계는 APG가 2.29 mg/L, AOS가 16.55 mg/L로 나타났고, 정량한계는 APG가 7.63 mg/L, AOS가 55.16 mg/L로 나타났다. 또한, 회수율 검증을 실시한 결과 APG는 99.29%, AOS는 96.11%로 나타나 회수율 100±10% 이내의 검증기준을 모두 만족하였다. 정밀성 및 정확성을 판단한 결과 APG의 정밀성은 상대표준편차 0.30%, 정확성은 0.26-0.52%로 분석되었으며, AOS의 정밀성은 상대표준편차 0.10%, 정확성은 0.01-0.52%로 분석되어 모두 상대표준편차 1.0% 이하의 검증기준에 적합하였다. 확립된 분석법을 주방세제에 적용하여 분석한 결과 샘플 3종 모두에서 APG와 AOS가 각각 검출되었으며, 표준사용량을 기준으로 APG, AOS의 평균 함유량은 각각의 LD50에 크게 미치지 못하는 것으로 나타났다. 따라서 본 연구를 통하여 확립된 음이온 및 비이온 계면활성제의 분석법은 모든 성분에 대해 감응함으로 한가지 검출기를 이용하여 여러성분을 동시에 측정할 수 있어 식기 등의 잔류물질 혹은 식품 중 혼입되어 있는 다양한 계면활성제 함유량 분석에 적용하여 계면활성제의 관리를 위한 기초자료로 활용될 것으로 본다.

백두산 폭발에 대한 국민의 우려 증대는 과학적이고 체계적인 화산연구가 부족했던 한국의 여러 분야에서 화산을 연구할 수 있는 환경을 마련해주었다. 화산은 고유의 지질학적 특성에 의거하여 폭발 양상이 달라지므로 모델링 및 일반화하기에 어려운 점이 있다. 또한 화산학자의 수가 매우 적어서 관련된 연구 프로그램 및 해외전문가의 협력이 절대적이다. 이에 V-hub, GVM, VOGRIPA라는 세 곳의 연구 그룹에 대한 기초조사 및 상호관계의 이해를 통한 기술협력 대상을 발굴할 목적으로, 홈페이지 분석, 관련자 방문 및 인터뷰를 수행하였다. 연구의 궁극적 목적은 백두산 연구를 통하여 구축될 화산연구포털을 단순한 벤치마킹이 아닌 차별화 및 기여라는 관점에서 시사점을 도출하고자 하는 것이다. V-hub 는 화산연구자들의 커뮤니티 사이트이자 자료공유의 사이트로, GVM은 내용을 채울 수 있는 연구와 데이터 공유를 위한 표준 마련이 주된 역할이며, VOGRIPA는 화산폭발사건에 대한 데이터베이스화와 정보표출을 목표로 하고 있다. 지도학 및 공간정보차원에서 보면 이들은 분석의 도구로 GVM에서 일부 다루어지고, VOGRIPA에서 화산의 위치를 웹GIS로 표출하는 수준에 국한되어 있다. 화산연구포털이 다음 단계로 발전하기 위하여, 한국이 기여할 수 있는 바와 지도학적으로 발전시킬 수 있는 항목 등을 제시하였다.
