We systematically analyzed the Wetland Conservation Action Plan of Gyeongsangnam Province to evaluate conservation status in local government level. Project topics were categorized into 1) wetland infrastructure, 2) wetland conservation and wise use, 3) education and awareness, and 4) conservation framework. From 2010 to 2013, 42 projects (145 cases, 88,899 million won) were implemented by 14 affiliated organizations under Gyeongsangnam Provincial Government. The number of projects and budget size has been decreased over 4 years, besides most of main projects were continued. The budgets were largely used for wetland project of cities and counties. Development and implementation of various conservation projects may have considerable potential values in wetland conservation, while it is still difficult to assess their overall effectiveness in the society. Diverse wetland management practices in Gyeongsangnam Provincial Government have accumulated fundamental practices and knowledge for an effective local conservation. These administrative experiences will further benefit other local government to establish wetland management framework. To accelerate policy diffusion to other local governments, Gyeongsangnam Province needs to promote and share leading experiences and information of wetland conservation. Enhanced local government framework by the legislation at central government will further support country-level management plans and practices.

This study was conducted to identify the factors predicting binge drinking in men and women in Korea based on the results of the 7th year 3rd National Health and Nutrition Survey. The study data used the demographic and health-related characteristics and drinking characteristics of the National Health and Nutrition Survey, and were analyzed by cross-sample analysis and logistic regression analysis. As a result of the study, age (M:p=.003, F:p<.001), drinking frequency for one year (M:p<.001, F:p<.001), amount of alcohol consumed at a time (M:p<.001) 001, F:p<.001), family/doctor's recommendation for moderation (M:p<.001, F:p<.001), stress (M:p=.025, F:p<.001), Smoking (M:p<.001, F:p<.001) were predictors for binge drinking in both men and women. In addition, education level(p=.030) and economic activity status(p=.018) for men, income level(p<.001) and marital status(p=.020) for women were identified as predictors of binge drinking, and variables explained 72.4%(p < .001) and 74.5%(p < .001) of adult male and female binge drinking. This study is meaningful in that it provided basic data on the establishment of a gender-specific binge drinking prevention policy and the restructuring of drinking culture by clarifying that the risk factors of binge drinking in Korean adults differ by gender.

현재 태양광에너지 시장은 해마다 빠른 속도로 성장하는 추세이며 50 GWp/년 이상의 시장으로 변화하였고 앞으로도 전체적인 성장세는 지속 유지될 것으로 판단된다. 하지만 이와 아울러 각 Value chain 별로 많은 기업들이 생겨나게되어 각각의 기업들이 제품을 고효율 저가화 함으로서 경쟁력을 확보하기 위해 많은 노력들이 기울이고 있으며 본 강연에서는 이러한 측면에서 태양광 에너지의 분야별 고효율/저가화를 위한 기술동향을 살펴보고자 한다. 태양광 산업은 아직은 다소 높은 발전단가로 인해 일부 정부의 지원이나 정책에 의해 산업의 규모가 결정되게 되는데 주요한 지원제도는 RPS 제도와 FIT 제도가 있으며 우리나라는 초기 FIT 제도로 국가에서 태양광에서 생산된 전기를 높은 가격에 사주었으나 근래에들어 RPS 제도를 운영하게 되었으며 매전을 하면서 SMP에 준하는 수익을 창출하고 이와 아울러 REC 를 확보하여 확보된 REC 단가에 의해 추가적인 수익을 창출하는 구조의 발전사업이 진행되고 있다. 그리고 RPS나 FIT와 같은 정부의 지원없이도 발전단가의 경쟁력을 확보하는 시점을 그리드패러티라고 하며 이는 매우 중요한 의미를 갖는다. 태양광의 저가화는 그리드패러티 달성을 확보하기 위해 필수적으로 필요한 사안이며 앞으로도 이러한 저가화 / 고효율화 기술노력은 계속 진행될 것으로 판단된다. 우선 소재의 가격을 줄이기 위해 웨이퍼의 두께가 점점 박형화 되어가고 박형화 되면서도 안정적인 공정수율 및 효율을 향상시키기 위한 기술개발이 진행되고 있으며 Cell 분야에 있어서도 고효율을 위한 다양한 Texturing 기술 및 패시베이션 기술의 개발이 이루어 지고 있으며 고효율 컨셉의 MRT cell, Back contact cell 등 고효율 구조의 cell의 양산을 진행하고 있는 등 최근 n-type 기반의 고효율 cell 기술이 활발하게 양산화 검토가 이루어 지고 있다. 모듈 분야에 있어서는 저가/고효율화와 아울러 제품의 신뢰성 확보가 무엇보다도 중요하게 다루어 지고 있으며 이는 모듈이 최소 25년 이상 Field 에서 운용되어 수익창출이 가능해야 하므로 가장 중요한 요소중에 하나라고 할 수 있다. 신뢰성 측면에서 중요하게 다루어 지고 있는 것 중 하나가 PID 저감을 위한 노력이며 이와 관련된 각 소재의 개발이 가장 활발하게 진행되고 있으며 이와 아울러 장수명을 보장하기 위한 내구성이 겸비된 봉지재의 개발 또한 많은 관심을 불러 일으키고 있다. 저가/고효율화를 위해 CTM loss를 줄이기 위한 다양한 시도가 이루어지고 있으며 특수 형태의 리본으로 빛의 흡수를 증가시키거나 컨택저항을 최소화 하기위한 소재의 개발이 이루어 지고 있다. 태양광 시스템 분야의 경우 발전량과 수익창출에 있어 직접적인 영향을 미치는 분야로서 전체 시스템의 loss 를 줄이고 최적의 환경에서 최대한의 발전량을 확보하기 위한 array 설계 및 운용기술이 활발하게 개발되고 있으며 시스템에서의 loss를 줄여줄수 있는 마이크로 인버터나 multi string 인버터의 적용도 이루어 지고 있으나 저가화를 위한 추가적인 노력이 필요한 상황이다. 본 강연의 마지막으로 이러한 노력들의 산물인 특수 태양광 제품 및 시스템의 기술동향에 대해 살펴하고자 한다. 사막은 전체면적의 1/3을 차지할 정도로 넓은 면적을 자랑하지만 밤과 낮의 기온차 그리고 계통 선로의 부재 등 적용하기 어려운 환경적인 제약도 함께 존재하며 이러한 문제를 해결하기 위한 방안에 대해 살펴보고 최근 Hot issue 중의 하나인 수상 태양광 시스템의 장, 단점과 기술적 특성 등을 살펴보고자 한다.

The purpose of this paper is to provide an answer for the following question: What are the major shifts and implications of the unprecedently competitive and rapidly changing media ecosystem in the era of N-screen and OTT services? I've attempted to understand the complex and competitive nexus among media from an historical context by focusing on the displacement vs. complement thesis. The TPC model by Han has been employed for the analysis of the current dynamics of US media industries by triangulating three areas: Technology/industry, public policy and consumer/culture. More specifically, the US media landscape is initially divided into two competitive turfs - the competitors equipped with OTT services and the legacy media industry, and then the traditional media industry was grouped again into PayTV group(telecom service providers with IPTV and mobile TV, cable/Satellite TV networks) and Free (over-the-air) TV networks. Six major shifts were identified by the analysis: power shift in telecom carriers, power shifts in TV industry, Telecom/OTT partnership, time shifts, place shifts, and finally business model shifts.

The study aimed to evaluate the effects of the EMDR-IGPT(Eye movement desensitization and reprocessing-integrative group treatment protocol) on the depression, anxiety, post traumatic stress, self-esteem in graduate nursing students. A quasi-experimental study employing a nonequivalent control group and pre-post design was conducted. The participants were graduate nursing students from C university (Experimental group=22, Control group=28). The experimental group participated in the 8 session-EMDR-IGPT for 8 weeks, while control group were treated by waitlist. Data were analyzed using ${\chi}^2-test$, independent t-test, with SPSS 24.0 program. There were significant differences in anxiety(t=-2.50, p<.05) and self-esteem(t=20.78, p<.01) of participants between experimental group and control group after completion of 8 session-EMDR-IGPT. The results indicate that EMDR-IGPT can be used to improve anxiety and self-esteem of graduate nursing students. Furthermore, further study needs to identify the mechanism of the effects of the program.

'Beauty and the Beast' was generated as a novel in 1740 and descended to date with the musical movie in 2017. This study is to understand what contents has been derived and expanded from one story for 277 years upon analyzing 'Beauty and the Beast' with the background of the times. Due to the limitation to include all the folktales and stories, the subjects of this study are limited with the contents that had been known and recorded as 'Beauty and the Beast.' 'Beauty and the Beast' has been expanded to 7 types of contents including novel, fairytale, movie, drama, animation, musical and film opera. It was created as a novel in the eighteenth century, made as a fairytale, and developed as a movie by Jean Cocteau, a movie director. With Industrial Revolution and the development of science, 'Beauty and the Beast' which derived into animation, drama, and musical contents, has been developed as the film opera thanks to the new trial of Philip Glass and the development of music industry. 'Beauty and the Beast' is still regenerating with a variety of contents continuously upon the development of computer technology and the fad of global remake. With anticipation of further analytical studies on 'Beauty and the Beast,' it is expected that the data of this study can be contributed as a reference in the other studies.

With the spread of COVID-19 worldwide, non-face-to-face services have grown rapidly, but at the same time, the problem of plastic waste is getting worse. Accordingly, eco-friendly policies such as carbon neutrality and sustainable circular economy are being promoted worldwide. Due to the high demand for eco-friendly products, the packaging industry is trying to develop eco-friendly packaging materials using PLA and PBAT and create new business models. On the other hand, Ulva australis occurs in large quantities in the southern seas of Korea and off the coast of Jeju Island, causing marine environmental problems. In this study, lactic acid was produced through dilute acid pretreatment, enzymatic saccharification, and fermentation processes to utilize Ulva australis as a new alternative energy raw material. In general, seaweeds vary in carbohydrate content and sugar composition depending on the species, harvest location, and time. Seaweed is mainly composed of polysaccharides such as cellulose, alginate, mannan, and xylan, but does not contain lignin. It is difficult to expect high extraction yield of the complex polysaccharide constituting Ulva australis with only one process. However, the fusion process of dilute acid and enzymatic saccharification presented in this study can extract most of the sugars contained in Ulva australis. Therefore, the fusion process is considered to be able to expect high lactic acid production yield when a commercial-scale production process is established.

A self-sufficiency service has worked as a typical workfare policy combined with public assistance in Korea since 2000. Despite of its long history, three core pillars in administrating the self-sufficiency service, policy, research, and practice, have respectively understood the meaning of self-sufficiency in terms of their own interests. As a result, the self-sufficiency service has recently faced with its own identity issues by showing failures to its environmental changes. The current situation makes it necessary to reconceptualize the definition of self-sufficiency by exploring its in-depth understanding perceived by service providers. Specifically, we analyzed practical reflections on 35 service providers' experiences which were collected via focus group interviews for two hours. The study findings presented that service providers had two antithetical approaches towards self-sufficiency. While a dominant approach to self-sufficiency has been concentrated on improving clients' economic outcomes such as employment, job retention, the escape from welfare trap, and increasing earnings and assets, the other approach has been extended to empower clients and achieve their well-being and quality of life. Yet, these contrary perspectives have led to suffer from their role confusions and identity crisis between the work-ready process and the employment-oriented outcomes. Specifically, they described self-sufficiency in terms of psychological, social, and integrated aspects. The psychological aspect included a process of developing inner strengths, intensifying job motivation, and coping with barriers of employment. The social aspect meant a path toward social integration through recovering human relationships. The integrated aspect covered more comprehensive support for their recovery of daily life and autonomy to make a decision for their own life. In conclusion, the study findings suggest that self-sufficiency should be more extensively considered as a stepwise process towards work-ready preparations beyond ultimate economic outcomes. Such an extended concept of self-sufficiency could contribute to restructuring the whole practice of self-sufficiency including organizational and program changes in the fields.

The purpose of this study is to present empirical evidence for discussion of financing social welfare via estimating optimal tax burden in the main member countries of the OECD by using Hausman-Taylor method considering endogeneity of explanatory variables. Also, the author produced an international tax comparison index reflecting theoretical hypotheses on revenue-expenditure nexus within a model to compare real tax burden by countries and to examine feasibility of tax increase in Korea. As a result of the analysis, the higher the level of tax burden was, the higher the level of welfare expenditure was, indicating the connection between high burden and high welfare from the aspect of scale. The results also indicated that the subject countries recently entered into the state of low tax burden. Meanwhile, Korea had maintained low burden until the late 1990s but the tax burden soared up since the financial crisis related to the IMF. However, due to the impact of foreign economy and the tax reduction policy, it reentered into the low-burden state after 2009. On the other hand, the degree of social welfare expenditure's reducing tax burden has been gradually enhanced since the crisis. In this context, the current optimal tax burden ratio of Korea as of 2010 may be 25.8%~26.5% of GDP based on input of welfare expenditure variables, a percent that Korea was investigated to be a 'high tax burden-low ITC' country whose tax increase of 0.7~1.4%p may be feasible and that the success of tax system reform for tax increase might be higher probability when compare to others. However, measures of increasing social security contributions and consumption tax were analyzed to be improper from the aspect of managing finance when compared to increase in other tax items, considering the relatively higher ITC. Tax increase is not necessarily required though there may be room for tax increase; the optimal tax burden ratio can be understood as the level that may be achieved on average when compared to other nations, not as the "proper" level. Thus, discussion of tax increase should be accompanied with comprehensive understanding of models of economic developmental difference from nations and institutional & historical attributes included in specific tax mix.

Since the Korean government has decided to apply the policy of BIM (Building Information Modeling) to the entire construction industry, it has experienced a positive trend in adoption and utilization. BIM can reduce workloads by building model objects into libraries that conform to standards and enable consistent quality, data integrity, and compatibility. In the domestic architecture, civil engineering, and the overseas landscape architecture sectors, many BIM library standardization studies have been conducted, and guidelines have been established based on them. Currently, basic research and attempts to introduce BIM are being made in Korean landscape architecture field, but the diffusion has been delayed due to difficulties in application. This can be addressed by enhancing the efficiency of BIM work using standardized libraries. Therefore, this study aims to provide a starting point for discussions and present a classification system for objects and attribute information that can be referred to when creating landscape libraries in practice. The standardization of landscape BIM library was explored from two directions: object classification and attribute information items. First, the Korean construction information classification system, product inventory classification system, landscape design and construction standards, and BIM object classification of the NLA (Norwegian Association of Landscape Architects) were referred to classify landscape objects. As a result, the objects were divided into 12 subcategories, including 'trees', 'shrubs', 'ground cover and others', 'outdoor installation', 'outdoor lighting facility', 'stairs and ramp', 'outdoor wall', 'outdoor structure', 'pavement', 'curb', 'irrigation', and 'drainage' under five major categories: 'landscape plant', 'landscape facility', 'landscape structure', 'landscape pavement', and 'irrigation and drainage'. Next, the attribute information for the objects was extracted and structured. To do this, the common attribute information items of the KBIMS (Korean BIM Standard) were included, and the object attribute information items that vary according to the type of objects were included by referring to the PDT (Product Data Template) of the LI (UK Landscape Institute). As a result, the common attributes included information on 'identification', 'distribution', 'classification', and 'manufacture and supply' information, while the object attributes included information on 'naming', 'specifications', 'installation or construction', 'performance', 'sustainability', and 'operations and maintenance'. The significance of this study lies in establishing the foundation for the introduction of landscape BIM through the standardization of library objects, which will enhance the efficiency of modeling tasks and improve the data consistency of BIM models across various disciplines in the construction industry.
