The purpose of this study aimed to examine the effects of ecological systems factors on childhood depression. A total of 2,119 children data from 2013 Korean Children & Youth Panel Survey(the fourth wave)were used in this study. The results of hierarchical regression showed the most ecological systems factors; organisms(child's gender, aggressiveness, attention problems), microsystems(parental neglect, parental abuse, good relationships with friends), exosystem(supportive community environment); had effects on depression. The most influential factors were child's aggressiveness, parental abuse, good relationships with friends, supportive community environment. Finally, this study suggested some implications for practical intervention and further research in childhood depression.

The discussion on the adoption of the horizontal regulatory framework is underway to overcome the problems regarding the vertical regulatory framework resulting from a convergence of broadcasting and telecommunications services. Recently, however, the horizontal regulatory framework shows its limitation to regulate the ecosystem established mainly by Google and Apple. The existing horizontal regulatory framework does not fully reflect the characteristics of the two-sided market and the change in the competition structure in the broadcasting and telecommunications sector. What is important to note is that if the existing horizontal regulatory framework is simply applied to the ecosystem, a regulatory imbalance can be caused among ecosystems. The existing horizontal regulatory framework, which is subject to a value chain structure, categorizes business entities into either contents layer or transmission layer and applies the same regulation to all business entities in the same category. However, in the ecosystem, a keystone-player can be categorized into different layers depending on its strategy. Therefore, if the existing horizontal regulatory framework is applied as it is, the regulatory imbalance between keystone-players located in less regulated areas and keystone-players located in more regulated areas occurs resulting in a distortion of competition. There are two possible ways to establish a new regulatory framework to prevent the distortion of competition likely to be caused by the adoption of a horizontal regulatory system. First, a new ecosystem regulatory framework different from the existing one can be established. Second, the horizontal regulatory framework can be modified to reflect the ecosystem elements. The first approach is hard to adopt given the current situation as the approach requires the analysis of all broadcasting and telecommunications ecosystems including mobile and wired services; currently research and study on the competition conditions in the ecosystems is not enough. Therefore, this paper supports the second approach proposing a modified horizontal regulatory framework through the improvement of institutions and remedies suitable for accommodating the ecosystem elements. This paper intends to propose a way to regulate broadcasting and telecommunications ecosystems taking into consideration the ecosystem elements on top of the Telecommunications Business Act, Broadcasting Act, IPTV Act, the competition condition evaluation system of the Basic Act on Broadcasting and Telecommunications Development, and regulation on common carriers under the Telecommunications Business Act.

The wetland ecosystem is a complex products of various erosion force, accumulation as water flows, hydrogeomorphic units, seasonal changes, the amount of rainfalls, and other essential element. There is no single, correct, ecologically sound definition for wetlands because of the diversity of wetlands and the demarcation between dry and wet environments occurs along a continuum, but wetland plays various ecosystem functions. Despite comprehensive integration through classification and impact factors there is still lacking in systematic management of wetlands. Classification system developed by the USFWS(1979) is hierarchical progresses from systems and subsystems at general levels to classes, subclasses, dominance types, and habitat modifiers. Systems and subsystems are delineated according to major physical attributes such as tidal flushing, ocean-derived salts, and the energy of flowing water or waves. Classes and subclasses describe the type of substrate and habitat or the physiognomy of the vegetation or faunal assemblage. Wetland classes are divided into physical types and biotic types. For the wise management of wetlands in Korea, this study was carried out to examine methodology of USFWS classification system and discuss its application for Korean wetland hydrogeomorphic units already known. Seven wetland types were chosen as study sites in Korea divided into some different types based on USFWS system. Three wetland types belonging to palustrine system showed no difference between Wangdungjae wetland and Mujechi wetland, but Youngnup of Mt. Daeam was different from the former two types at the level of dominant types. This fact means that setting of classification system for management of wetland is needed. Although we may never know much about the wetland resources that have been lost, there are opportunities to conserve the riches that remain. Extensive inventory of all wetland types and documentation of their ecosystem functions are vital. Unique and vulnerable examples in particular need to be identified and protected. Furthermore, a framework with which to demonstrate wetland characteristics and relationships is needed that is sufficiently detailed to achieve the identification of the integrity and salient features of an enormous range of wetland types.

This review paper examines various terms used for the definitions and classifications of ecosystem services, often times mixed and confused, in the literature and re-establishes the concepts of important terms, including ecosystem functions, services and benefits, to enhance communication among the stake-holders in the process of decision making. The definitions and scopes of ecosystem services are differentiated depending on the policy purposes such as environmental accounting, environmental valuation and natural resource management. The importance of identification and enumeration of final outputs associated with a particular policy is addressed. In addition, the usefulness of an alternative pathway-analysis beginning from benefits, via services and function, to process/structure of ecosystem is emphasized.

기후변화로 인해 집중호우 등 설계강우량을 초과하는 강우가 빈번하게 발생하고 있으며, 이에 따라 농촌유역의 홍수 및 침수의 발생빈도 및 강도가 증가하고 있다. 국내 농업용 저수지 약 17,500여개 중 약 70%는 70년 이상 경과된 노후시설로 분류되고 있으며, 특히 농어촌공사에서 관리하는 3,411개의 저수지를 제외한 시군관리 저수지는 체계적인 유지보수가 이루어지지 않고 있다. 이로 인해 홍수기 농업용 저수지의 월류 및 붕괴에 따른 하류지역 침수 피해가 빈번하게 일어나고 있다. 농촌유역 침수 피해 저감을 위한 대책을 수립하기 위해서는 먼저 정확한 침수 피해 평가가 수행되어야 하지만, 우리나라에는 현재 농촌유역에 특화된 침수 피해 평가 체계가 부족한 실정이다. 본 연구에서는 농촌유역의 맞춤형 침수 피해 평가 체계를 개발하고자 한다. 농촌유역의 농업용 저수지를 포함한 농업수리구조물의 붕괴 등에 따른 하류 침수 모의 기법을 개발하고, 농작물의 종류를 고려한 침수심 및 침수시간에 따른 침수피해 모의 체계를 개발하고자 한다. 본 연구에서 개발한 농촌유역 맞춤형 침수 피해 평가 체계는 향후 농촌유역의 체계적인 재난관리를 위한 정책 수립에 활용될 수 있을 것으로 기대된다.

This study conducted researches to get related basic materials and grope for a way to prevent or treat suicidal ideation. For the researches, the study examined eco-systematical variables of suicidal ideation of those who are 65 years or older, and the influence of the change in the eco-systematical variables by using the source materials researched in sixteen cities/provinces over the country from KOWEPS(Korea Welfare Panel Study), and then reviewed if there any difference according to whether they had suicidal ideation or thought in the previous year. The analysis result shows that each variable of the ecological system such as individual, family, and social system has an effect on the elderly's suicidal ideation, and there is difference in the influence factor according to whether they had suicidal ideation in the previous year or not. The result implies the policy to cope with the elderly's suicide needs multidimensional approach of individual, family, and society rather than a simple individual level. And also there should be a different support or service according to their situation or conditions like previous suicidal ideation. Especially, it is quite significant that the factors do not influence the elderly who had suicidal ideation in the previous year, but have an effect on those who did not have any suicidal ideation, which means that the proactive and preventive support related to suicidal ideation would guarantee a more efficient and effective policy.
