Landscape changes for 20 years between 1981 and 2001 in the Wangsuk stream basin located on the central Korea were investigated on the basis of physiognomic vegetation map made from the aerial photograph interpretation and field check. Changes of landscape structure were noticeable in agricultural field and forest landscape elements. Changes in the agricultural fields due to transformation of agricultural pattern into the institutional agriculture dominated landscape change, although urbanization also contributed to such change. The former change due to change of food production structure originated from socio-economic development during this period and the latter to the overpopulation of Seoul. As energy sources for heating and cooking, fertilizer, and fodder for livestock transform from plant materials to fossil fuel, manufactured one, and grain, succession of forest escaped from direct human disturbance dominated change of landscape structure in forested land. Differently from the positive landscape change in the upper area, change in the lower area deteriorated landscape quality by increasing artificial land. It was estimated that such landscape deterioration in the Wangsuk stream basin would influence water quality of the stream. In order to realize sustainable land-use against such environmental degradation, systematic environmental management based on landscape ecological perspective such as "an eco-plan for creating riparian vegetation belt," which is under preparation by Ministry of Environment, was recommended.

This study was designed to examine the degree of dependence on dietary environment, evaluate the perception of metal service program and investigate factors affecting the demand for meal service programs for elderly parents. The purpose of this study provided the basic information for the development and systemization of meal service program for elderly. Eight hundred twenty semen adults who have elderly parents were surveyed using pre-designed written questionnaire. According to the results on the life environments of their elderly parents, psychological factors(41.7%), living condition(14.3%) and dietary environment (13.2%) had trouble. Physical and psychological conditions significantly affected the dietary environment(p<0.05). Only 9.2% of the subjects were already aware of recognized the meal service program for elderly, and the degree of recognition differed significantly by sex and education level. Women had better perception of meal service program for elderly than men. In men, they would expect to use congregate meal service(44.1%), home-delivered meal service (23.7%), nursing home meal service(16.9%) in order. On the other hand, for women, home-delivered meal service (41.2%), congregate meat service(44.1%), and nursing home meal service (16.8%) in order. Therefore there are significant differences between men and women what type they want(p<0.001). For those who haute both of the parents or either one of them, they would use more of congregate meal service (38.8%) and home-delivered meal service (38.8%) than nursing home meal service (15.5%). The group whose parents are lower socio-economic status would have tendency to use the nursing home meal service (p=0.06). The group of whom believe the dietary environment is the problem of their parents'life environment had preference of using congregate meal service and home-delivered meal service.

In this study, priority for groundwater contamination management was assessed based on regional vulnerability in Goyang-si area, Gyonggi-do, Korea using analytic hierarchy process (AHP) and geographic information system (GIS). We proposed a concept for regional vulnerability to groundwater contamination with using socio-environmental vulnerability factors, which can be classified into three properties including regional hydrogeological property, contamination property, and groundwater use property. This concept is applied to Goyang-si area. For AHP analysis, an expertise-targeted survey was conducted. Based on the survey, a total of 10 factors (criteria) and corresponding weights for regional vulnerability assessment were determined. The result shows that regional contamination property is the most weighted factor among the three property groups (hydrogeological property: contamination property: groundwater use property = 0.3: 0.4: 0.3). Then, database layers for those factors were constructed, and regional vulnerability to groundwater contamination was assessed by weighted superposition using GIS. Results show that estimated regional vulnerability score is ranged from 22.7 to 94.5. Central and western areas of Goyang-si which have groundwater tables at shallow depths and are mainly occupied by industrial and residential areas are estimated to be relatively highly vulnerable to groundwater contamination. Based on assessed regional vulnerability, we classified areas into 4 categories. Category 1 areas, which are ranked at the top 25% of vulnerability score, take about 2.8% area in Goyang-si and give a high priority for groundwater contamination management. The results can provide useful information when the groundwater management authority decide which areas should be inspected with a high priority for efficient contamination management.

Since the experience of major landscape change during last half of the century due to war and rapid urbanization, the traditional character has been weakened, and it is necessary for a reconsideration to improve the landscape for the future. To review these relationships, the importance of a comprehensive understanding of nature has been suggested. Therefore identification of a new concept based on the 'socio-cultural influence of landscape' and 'sense of place' which are related to peoples' previous experience, is required. Furthermore more practical definitions and criteria to reveal the relationship are necessary. Among the terms suggested to describe sense of place such as 'home', 'place identity', 'place-based meaning' and 'settlement identity' etc., the 'home' is selected to represent our surrounding landscape. For more practical classification of home landscape, additional terms are suggested and defined based on both the relationships between human beings and nature, and between memory derived from previous experience and shared values with in the community. The additional terms which are the most important in the role of landscape character related to humans' are; ⅰ) Personal Landscape: Landscape of an individual human, which derives from previous personal experience; involves distinguishable character for a given person, and it is emotional and flexible depending on circumstances. ⅱ) Ordinary Landscape： Landscape of the 'common interest' between members of a community, which is acceptable as a surrounding for everyday daily life, it produces the richness and variety of landscape. ⅲ) Kernel Landscape： Landscape of the 'common ground' which is acceptable to the majority members of the community, and it provides variety and stability for periods of time, and it could strongly represent community attitudes toward nature. ⅳ) Prototype Landscape: Landscape as the 'common denominator' of overall community from past to present and towards the future, which encompasses all the kernel landscape throughout history. It provides a sense of place, balances the homogeneity of character throughout overall communities. Some part of this can be shared throughout history to shape an overall sense of place. It can also represent short terms fashions. For a prototype landscape to reveal sense of place, there are a couple of points which we should underline the commencing point. Firstly, understanding the relationship between humans and nature should be based on a given character of surroundings. Secondly, reoccurring landscape elements which have sustained in history can lead to sense of place, and should be reviewed the influences between nature and humans.

국내의 하천 환경은 4대강 사업 이후로 많은 변화가 예상되며, 이 과정에서 하천관리기법 역시 변화가 요구되고 있다. 준설이 그 대표적 예라고 할 수 있지만 준설은 2차 환경피해의 우려가 있다. 이를 위해서 준설의 사회 환경적으로 미치는 부정적인 영향을 최소화하기 위하여 미국의 환경창 제도를 한국에 적용시켜보았다. 자료의 부족을 극복하기 위해 통계학적 기법을 이용한 방안을 제시하였으며, 낙동강 강정고령보 하류부에 적용해보았다. 그 결과, 1개월 동안 준설하는 경우에는 3월에 수행하는 것이 최적으로 나타났으며, 8개월 동안 준설하는 경우에는 8월에 수행하는 것이 최적인 것으로 나타났다. 여기에 홍수기를 고려했을 경우에는 8개월 동안 준설에 대해서 10월에 시작하는 것이 최적인 것으로 나타났다. 환경창 제도와 같이 비구조적 방법은 친환경 준설장비를 개발하는 등의 구조적 방법보다 제도만 잘 정비된다면 단기간에 효과를 볼 수 있으며, 친환경 준설장비를 개발하면서 소요되는 막대한 예산을 절감할 수 있다는 장점이 있으므로 환경창을 준설규정을 수립하는 데 있어서 참고할 수 있을 것으로 판단된다. 환경창의 국내 적용은 하천준설에 대한 연구가 미비했던 국내에 기초자료로써 제공될 수 있을 것으로 판단된다.

When individuals collaborated in virtual settings, communication is medicated through a variety of communication technologies, and is associated not only with communication effectiveness but also with socio-emotional interactions among group members. In this regards, scholars have examined how technology-mediated communication systems can be designed and used to facilitated communication interaction. However, the empirical results of the previous studies have revealed inconsistencies in the effects of communication media on users' behavioral or attitudinal responses, and on their viable effectiveness in organizations. Some studies claim that computer-mediated communication(CMC) is task-oriented but not suitable for emotional expression since it hinders close interpersonal interaction. On the other hand, some studies argue that individuals are able to develop interpersonal relationships more effectively in a CMC environment than in an FtF-environment. Due to the different perspectives, a theoretical gap exists, and it leads to the inconsistent research findings. The purpose of this paper is to combine the two different perspectives into single unified model, thereby providing a more realistic and comprehensive understanding about virtual collaboration. The present study here sought to answers the following questions with organizational communication perspective: What are the major components of virtual collaboration? What factors affect the performance of virtual collaboration? And what kind of managerial efforts should organization make in order to facilitate CMC media effectiveness in virtual collaboration? Although there is a certain belief that new media, namely technology-mediated communication support would create new opportunities, the problem of "how" or "why" has been an important question that is still not fully addressed. In this regards, we collectively reexamined previous literatures with major issues which are still controversial and integrated various theoretical activity within computer-mediated communication domain: task-oriented approach, socio-emotional approach, and evolutionary psychological approach. Our first contribution is to develop a framework for virtual collaboration by combining two different perspectives into a single unified model, providing a more realistic and comprehensive understanding. The second main contribution is the joint modeling of both social presence and cognitive effort, and the effects on two distinct but important communication outcomes(i.e., take performance and relational development). We tested the research hypotheses which were developed based on the various CMC theories using data gathered through a self-administered mail survey of 127 individuals of 69 virtual workgroups. The proposed model was supported, providing preliminary evidence that the tension between two opposite view should be integrated. The results show that the individual's psychological processes(social presence and cognitive effort) in a virtual environment significantly mediated the effect of CMC inputs (media richness, user adaptation, and shared contest) on the CMC outputs (task performance and relational development). Furthermore, this study shows that the lack of perceived media richness of CMC media can be complemented by user adaptation and shared context. Based on the results, we discuss how communication system should be designed and implemented so as to promote virtual interaction as well as how a virtual workgroup should be composed to complement the lack of media richness. A virtual collaboration using CMC media may create new value by overcoming the logistical constraints. On the other hand, it may also generate various managerial risks such as communicational depersonalization, process dissatisfaction, and low cohesion. Therefore, this study suggests that organization managers should carefully choose the CMC mediums and monitor individual member's cognitive and affective psychological processes during virtual collaboration to reduce potential risks in virtual collaboration.

과거에는 대기오염, 수질오염, 폐기물 등이 환경영향평가에서 주요한 평가항목이었는데 최근에는 토지환경(토지이용, 지형), 자연생태환경(동·식물상, 자연환경자산), 사회·경제 환경 등이 주요한 평가항목으로 다뤄지고 있다. 2012년 이후 전략환경영향평가와 소규모환경영향평가의 협의결과를 보면, 90 %이상이 조건부동의였다. 그러나 환경영향평가의 협의결과는 2012년~2016년 기간 거의 대부분(94.1 %) 동의였으나, 환경정책기조가 바뀌는 2017년 이후부터 대부분(87.4 %) 조건부동의로 결정되었다. 그리고 세 종류 환경영향평가의 부동의 비율이 2013년~2016년 기간 0.3~0.6 % 밖에 되지 않았는데, 2017년~2019년 기간 1.3~3.1 %로 급증하였다. 그 사이 협의 결과에 영향을 미칠만한 제도나 분석기법의 변화가 없었다면, 협의결과의 일관성 및 공정성의 결여가 문제로 제기될 수 있다. 따라서 환경영향평가에서 입지타당성을 결정하는 토지이용, 동·식물상 및 자연환경자산, 사회·경제 등의 평가항목에 대한 지표개발과 적용에 대한 연구가 요구되고 있다. 본 연구는 환경영향평가가 전략환경영향평가, 환경영향평가, 소규모환경영향평가로 구분되어 시행되는 2012년 이후 동의, 조건부동의, 부동의 협의결과를 분석한다. 부동의 사례에 대해 6개 환경분야 중 입지타당성분석에서 중요한 토지환경과 자연생태환경의 평가항목을 중심으로 근거요인을 분석하고, 환경관련 토지이용규제와 환경관련 등급을 중심으로 개발계획이나 개발사업에 대한 환경영향평가에서 협의 결정의 개선방안을 모색한다.

The ability of any organization to innovate itself in a rapid change of environment means the existence of the organization. Innovative activity is achieved in different ways according to the objectives of organization. the characteristics of external environmental factors. and various attributes in organization. In the present study. all the existing approaches to the innovative nature of organization were synthetically compared to each other and evaluated: then. for a more rational approach. a research model was built and suggested by establishing the inclusive variables of the innovative nature of library organization and categorizing the types of such nature. Additionally. an empirical. analytical study on such a model was done. That is. paying regard to the fact that innovation has basically a close relation with the circumstantial factors of organization. synthetic, circumstantial relations were clarified. considering the external environmental factors and internal characteristics of organization. In the study. the innovation of library organization was seen in two parts i.e .. the feasible degree of technical innovation and the feasible degree of administrative innovation. Regarding the types of innovative implementation. according to the feasible degree of innovation, four types such as a stationary type. technic-oriented type, organization-oriented type. and technical-socio systematic type were classified. There were nine independent variables-i.e., the scale of organization. available resources of the organization, formalization, differentiation, specialization. decentralization, recognizant degree of the technical attribute. degree of response to the change of technical environment, and professional activities. There were three subordinate variables - i.e., technical innovation, administrative innovation. and the performance of organization. Through establishment of such variables, the factors which might influence the innovation of library organization were understood, and with the types of the innovative implementation of library organization being classified according to the feasible degree of innovation. the characteristics of library organization were reviewed in the light of each type. Also. the performance of library organization according to the types of the innovative implementation of library organization was analyzed. and the relations between the types of innovative implementation according to circumstantial variables and the performance of library organization were clarified. In order to clarify the adequacy of the research model in the methodology of empirical study, data were collected from 72 university libraries and 38 special libraries. and for a hypothetical test of the research model. an analysis of correlations, a stepwise regression analysis. and One Way ANOVA were utilized. The following are the major results or findings from the study 1) It appeared there is a trend that the bigger the scale of organization and available resources are, the more active the professional activity of the managerial class is, and the higher the recognizant degree of technical environment (recognizant degree of technical attributes and the degree of response t9 the change of technical environment) is, the higher the feasible degree of innovation becomes. 2) It appeared that among the variables influencing the feasible degree of technical innovation, the order from the variable influencing most was first, the recognizant degree of technical innovation: second, the available resources of organization: and third, professional activity. Regarding the variables influencing the feasible degree of administrative innovation from the most influential variable, it appeared they were the available resources of organization, the differentiation of organization. and the degree of response to the change of technical environment. 3) It appeared that the higher the educational level of the managerial class is, the more active the professional activity becomes. It seemed there is a trend that the group of library managers whose experience as a librarian was at the middle level(three years to six years of experience) was more active in research activity than the group of library managers whose experience as a librarian was at a higher level(more than ten years). Also, it appeared there is a trend that the lower the age of library managers is, the higher the recognizant degree of technical attributes becomes. and the group of library managers whose experience as a librarian was at the middle level (three years to six years of experience) recognized more affirmatively the technical aspect than the group of library managers whose experience as a librarian was at a higher level(more than 10 years). Also, it appeared that, when the activity of the professional association and research activity are active, the recognizant degree of technology becomes higher, and as a result. it influences the innovative nature of organization(the feasible degree of technical innovation and the feasible degree of administrative innovation). 4) As a result of the comparison and analysis of the characteristics of library organization according to the types of innovative implementation of library organization. it was indicated there is a trend that the larger the available resources of library organization, the higher the organic nature of organization such as differentiation. decentralization, etc., and the higher the level of the operation of system development, the more the type of the innovative implementation of library organization becomes the technical-socio systematic type which is higher both in the practical degrees of technical innovation and administrative innovation. 5) As a result of the comparison and analysis of the relations between the types of innovative implementation and the performance of organization, it appeared that the order from the highest performance of organization is the technical-socio systematic type, then the technic-oriented type, the organization­oriented type, and finally the stationary type which is lowest in such performance. That is, it demonstrated that, since the performance of library organization is highest in the library of the technical-socio systematic type while it is lowest in the library whose practical degrees in both technical innovation and administrative innovation are low, the performance of library organization differs significantly according to the types of innovative implementation of library organization. The present study has extracted the factors influencing innovation, classified systematically the types of innovative implementation, and inferred the synthetical, circumstantial correlations between the types and the performance of organization, and empirically inspected those factors. However, due to the present study's restrictive matters and the limit of the research design, results from the study should be more prudently interpreted. Also, the present study, as an investigative study of the types of innovative implementation, with few preceding studies, requires more complete hypothetical inference based on the results of the present study. In other words, if more systematical studies are given to understanding the relations, it will devote the suggestion and demonstration of a more useful theory.

Background: Webtoon, a digital form of comics created in the Republic of Korea, has spread widely with advantages that anyone can become a cartoonist and that autonomy of creation is guaranteed. The purpose of this study is to identify the working conditions of webtoon writers and analyze the relationship between these conditions and depressive symptoms. Methods: A survey was carried out on webtoon writers and a survey data of 312 webtoon writers were analyzed. The questionnaire included basic socio-demographic characteristics, webtoon writers' contractual type, fields of activity (webtoon creator, story writer, illustrator), and working environment (labor discretion etc.). We investigated depressive symptoms and analyzed its relation to the work environment of webtoon writers. Results: Webtoon writers were exposed to long working hours, high labor intensity, limited labor discretion, negative comments from readers, and had a high prevalence of depressive symptoms. Compared to story writers who contracted directly with platforms, story writers and the illustrators who contracted with content providers (CPs) were 9.51 times (OR = 9.51, 95% CI = 1.47 - 61.33) and 6.47 times (OR = 6.47, 95% CI = 1.08 - 38.75) more likely to have depressive symptoms, respectively. Conclusions: This study emphasizes the urgent necessity to improve the overall working environment in the webtoon industry and implement measures to tackle the escalating mental health challenges faced by illustrators and story writers contracted with CPs, especially given the increasing popularity of novel comics.
