물관리는 밀레니엄개발목표(Millennium Development Goals)의 달성과정에서 가장 강조되는 주제 중의 하나이다. 물관리의 최종목표는 물관리 그 자체가 아니라 자연적으로는 유한한 수자원의 지속가능성을 유지하고 사회적으로는 계층간의 형평성을 실현하는 것이다. 그러나 개발도상국들은 한정된 국가재정으로 기반시설의 투자가 부족하고 기후변화에 따른 자연재해의 빈발로 인하여 인간다운 삶의 질을 보장받기 어려운 상황에 직면하여 있다. 이러한 인식 아래, 미국, EU, 일본 등의 선진국은 물론 이웃 중국도 개발도상국을 대상으로 물 관련 사업의 공적개발원조(ODA) 프로그램을 활발하게 추진하고 있다. 최근 우리나라의 대 개도국 협력사업은 한국국제협력단(KOICA)이 수행하는 ODA 사업을 중심으로 큰 폭으로 늘어나고 있다. 우리나라의 물 분야 지원사업도 식수개발, 댐건설, 관개시설 개발, 수질오염처리, 재해방지 예 경보 시스템 및 홍수조절사업 등으로 다방면에 걸쳐 활발하게 진행되어 왔다. 그러나 우리나라의 물 분야 ODA 사업은 정책 및 제도에 대한 컨설팅이나 교육훈련 등 소프트웨어 기반의 원조개발협력은 상대적으로 미진하고 물리적 인프라 위주의 지원사업이 대부분을 차지하고 있다. 최근에는 전문가 파견 및 연수생 초청 등의 인적협력의 사례가 증가하고 있으나 아직까지는 사업내용의 대부분이 건물, 시설물 및 기자재 등의 구조적인 지원 형태로 이루어지고 있다. 이러한 형태는 일찍이 대개도국 물 분야 사업을 추진한 미국이나 일본 등의 선진국들이 원조협력사업의 일관성과 지속성을 평가하기 위하여 제도적이고 정책적인 지원을 확대하는 것과는 거리가 있다. 1992년 KOICA가 네팔 모디강 수력발전소 실시설계 지원으로 시작된 우리나라의 물 분야 사업도 이제 20년에 이르고 있다. 물 분야 지원사업도 새로운 방향전환이 필요한 시점이다. 본 연구에서는 우리나라의 물 분야 ODA 지원사업의 현황과 문제점을 파악하고 향후 나아가야 할 정책방향을 제시한다. 이를 위하여 먼저 아시아의 스리랑카와 아프리카의 에티오피아의 2개 국가를 사례지역으로 선정하고 물관리의 현황과 문제점을 파악한다. 그리고 사례지역에 대한 우리나라의 물 분야 ODA 지원사업의 현황과 당면과제를 분석한다. 마지막으로 선진국과 우리나라의 물분야 지원사업의 추진방향을 비교분석하여 우리나라 물 분야 ODA 지원사업이 지향할 방향성을 제시한다.

Spring phonology of the oriental fruit moth, Grapholita molesta, was monitored using sex pheromone traps in apple cultivating areas. Their occurrence was earlier in southern areas and their population sizes were significantly different among orchards even in a local cultivating zone. The overwintering populations appeared to move between local orchards, based on the fact that monitoring data obtained at the sites between orchards were similar to those of nearby orchards. However, within orchards, these adult movements appeared to decrease and showed skewed occurrences at the side of upwind direction or close to neighboring orchards. At initial occurrence peak(April 20-25), the ovenvintering populations of the different localities were collected and analyzed in their genetic distances. PCR-RAPD analysis indicated that there were significant genetic differences among the overwintering populations of G. molesta. This genetic differentiation of overwinterin populations may be due to genetic bottleneck following differential selection pressures against the subpopulations of G. molesta during winter on the basis of the RAPD analysis that each early spring population was significantly different to its previous fall population in the same locality.

새만금호의 목표수질 달성과 지속가능한 관리를 위해서는 비점오염 관리의 필요성이 강조되고 있다. 특히, 새만금호 상류 유역은 농경지 비율이 38%로서 높아 농업활동에서 유래하는 농업 비점오염원의 효과적인 관리가 필요하다. 이를 위해서는 농업비점오염 저감기술의 개발하는 물리적 기술적 접근만이 아니라 농업인과 지역주민의 참여와 함께 행정적인 지원을 포함하는 사회 경제 문화적 접근을 포함하는 통합적인 접근 즉, 거버넌스가 요구된다. 이러한 거버넌스를 새만금유역의 농업비점 관리에 적용하려는 노력의 일환으로 "새만금유역 농업비점오염관리 거버넌스구축 사업모델 개발"에 대한 연구를 2015년부터 2016년까지 2년간 추진하게 되었다. 본 연구의 목적은 농업비점오염 관리를 위한 거버넌스 구축과 운영에 필요한 요소들을 도출하고 각각의 요소별 추진 프로세스를 개발하고 최종적으로 이를 상호 연계하여 운영하는 기법을 개발하는 것이다. 농업비점오염관리 거버넌스 구축의 접근 방향으로는 신규구축형과 기존정책사업연계형으로 접근하는 것이 바람직 할 것으로 판단된다. 거버넌스 시스템은 참여단위와 행정단위, 그리고 이것을 연계 지원하는 '중간지원조직'의 다층적 거버넌스 구조로 제안하였다. 참여단위 거버넌스는 공동체단위와 개별 농가단위의 참여 프로그램으로 설계하였다. 특히, 참여단위 거버넌스의 지속성을 유지하기 위해서 커뮤니티비즈니스 육성이 필요할 것으로 나타났다. 1차년도(2015년)에는 신규구축형을 중심으로 진행을 위하여 전라북도 부안군 백산면 용계리를 연구대상 지구로 선정하였다. 참여단위 거버넌스 구축을 위하여 연구대상 지구에서 우리 마을과 물 이야기, 우리마을회의 등 통하여 주민이 생각하는 지역의 역사와 문화 등 잠재자원을 발굴하였고, 이를 바탕으로 침체된 마을 공동체를 마을길을 연결하여 다시 활성화 하고, 물이 흐르는 마을도랑으로 가꾸고, 단절된 이웃간 마음을 연결하기 위한 "마을길-물길-마음길 연결" 커뮤니티 비즈니스 프로젝터를 도출하였다. 이러한 거버넌스구축 프로그램의 정보의 공유와 확산을 위하여 커뮤니티 비즈니스 안내판을 설치하고, 마을소식지(청파)를 제작배부하고 거버넌스구축 과정을 담은 마을영상다큐 제작을 진행하였다. 2차년도에는 커뮤니티 비즈니스 심화과정을 운영하고자 한다. 본 연구의 결과는 앞으로 농촌지역의 비점오염관리를 위한 거버넌스구축 등 정책 및 제도개선에 도움이 될 것으로 기대된다.

Animation is a popular art in the form of enlightenment that intimately approaches people of various ages and makes them reconsider the social problems they have ignored. Therefore, this paper analyzes how the character setting and formative symbolism in "The Willoughbys" raise awareness of social agendas. The previous studies found that the modern society needs to be aware of child abuse and various types of family, and examined that color and formativeness of animation induce psychological and behavior change from the audience. The work shows emotional abuse and neglect as characters, and presents the subdivided form of the family. The rainbow symbolizes diverse family members. The agents with visual characteristics express the modern principle-based secondary perpetrator along with apathetic neighbors to urge a change in audience perception. This paper insists the value of animation when it is essential to raise public awareness prior to the construction of a welfare society and support system.

Recently, the influence of the residential value of new town apartment houses has been increasing in the housing market; however, there has been little study on the relationship between the housing value and customer loyalty. This study analyzed the influence of the housing value on housing satisfaction and customer loyalty. To this end, this study conducted a survey targeting 519 residents in the second term new town. Accordingly, basic statistics, reliability and hypothesis test were carried out using SPSS 21.0 and ANOVA as an analysis method. The study results are as follows. First, as a result of factor analysis of the housing value, the factor was analyzed as 6 sorts, such as safety, sociality, convenience, economic feasibility, aesthetics, and comfort. Second, safety, comfort, and convenience among the factors in the housing value were found to have a significant influence on the housing satisfaction. This means that the concepts of property and assets reflect the development of new urban city apartments. Third, a new town house purchaser's positive housing value and housing satisfaction were found to increase customer loyalty. This greater satisfaction of the current residential apartment dwellers means that they are more likely to introduce their relatives and neighbors. These results suggest that a positive outlook of a new town householder on the housing value and housing satisfaction will eventually work more on revitalizing the housing market.

This study examines 2014 National Survey on Older Koreans (10,279 persons aged 65 or above) to understand social networks among older Koreans. In order to classify the types of social relationships, the latent profile analysis is conducted based on such structural aspects of social networks as network size, frequencies of contact, and closeness. The results show that older Koreans can be categorized into 5 distinct social network types: disengaged (11.6%), ritual-family-focused (17.7%), close-family-focused (23.6%), close-restricted (28,4%), and diverse (18.8%). Characteristics by each social network type are compared and multinominal logistic regression analyses are applied to figure out the influencing factors of social network type. Older persons with disengaged social network ties tend to be overwhelmingly female, living alone, old-old, and of low socioeconomic status. On the other hand, older persons with diverse social network ties tend to be young-old and had highly-ranked jobs in their mid-life. Spouse/children are the focal point of social relationships in both ritual-family-focused and close-restricted social network. However, the proportion of men is higher in the close-family-focused type than in the ritual-family-focused. Older Koreans with close-restricted social network ties tend to be female, uneducated, and have engaged in agricultural and allied activities. This study discusses the implications of its findings and how research in this area should develop in the future.

A discrete dynamic model for tracking feature points in 2D images is developed. Conventional snake approaches deform a contour to lock onto features of interest within an image by finding a minimum of its energy functional, composed of internal and external forces. The neighborhood around center snaxel is a space matrix, typically rectangular. The structure of the model proposed in this paper is a set of connected vertices. Energy model is designed for its local minima to comprise the set of alternative solutions available to active process. Block on tracking is one dimension, line type. Initial starting points are defined to the satisfaction of indent states, which is then automatically modified by an energy minimizing process. The track is influenced by curvature constraints, ascent/descent or upper/lower points. The advantages and effectiveness of this layer approach may also be applied to feature points tracking of digital image whose pixels have one directional properties with high autocorrelation between adjacent data lines, vertically or horizontally. The test image is the ultrasonic carotid artery image of human body, and we have verified its effect on intima/adventitia starting points tracking.

Wireless Sensor Network (WSN) is a wireless network consisting of spatially distributed autonomous devices, using sensors to cooperatively monitor physical or environmental conditions. WSNs face the critical challenge of sustaining long-term operation on limited battery energy. Coverage maintenance has been proposed as a promising approach to prolong network lifetime. Mobile sensors equipped with communication devices can be leveraged to overcome the coverage problem. In this paper, we propose a stepwise movement scheme using perimeter coverage property for the coverage maintenance problem. In our scheme, each sensor monitors neighboring dead nodes, determines vulnerable node (i.e. dead node which makes uncovered area), computes the center of uncovered area HC, and makes a coordinated stepwise movement to compensate the uncovered area. In our experimental results, our scheme shows at least 50 % decrease in the total moving distance which determines the energy efficiency of mobile sensor.

Studies on predicting arrhythmia using machine learning have been actively conducted with increasing number of arrhythmia patients. Existing studies have predicted arrhythmia based on multivariate data of feature variables extracted from RR interval data at a specific time point. In this study, we consider that the pattern of the heart state changes with time can be important information for the arrhythmia prediction. Therefore, we investigate the usefulness of predicting the arrhythmia with multivariate time series data obtained by extracting and accumulating the multivariate vectors of the feature variables at various time points. When considering 1-nearest neighbor classification method and its ensemble for comparison, it is confirmed that the multivariate time series data based method can have better classification performance than the multivariate data based method if we select an appropriate time series distance function.
