An infatuation with webtoons is facilitated by the ultra-rapid internet infrastructures and the highest ratio of penetration of smartphones in the world. Recently, the webtoon has been the focus of a new cultural content and its development has been noticed both and home and abroad. This study aims to find the new role of webtoon as a socio-cultural communication media. The webtoon reflects the reality as it is and shows directly and minutely the social problems, even although the other media make it glorified or reduced. We observe the role of webtoon as a new communication media content that can make the place for social discussion within several generations and social stratums, in which the producer and the consumer can communicate directly and immediately. Two webtoons( and ) have been selected for a textual analysis. In two webtoons, we analyse the method of representation of the social problem in the technique of expression and storytelling. This helps us maintain that the webtoon deserves as the socio-cultural communication media and the social problems represented in webtoon must have been evaluated more valuable in a new perspective.

Nowadays, the PV systems have been focused on the grid connection between the power source and the grid. The PV inverter can be considered as the core of the whole system because of an important role in the grid-interfacing operation. An important issue in the inverter control is the load current regulation. In the literature, Proportional Integral (PI) controller, which is normally used in the current-controlled Voltage Source Inverter (VSI), cannot be a satisfactory controller for an AC system because of the steady-sate error and the poor disturbance rejection, especially in high-frequency range. Compared with conventional PI controller, Proportional Resonant (PR) controller can introduce an infinite gain at the fundamental frequency of the AC source; hence it can achieve the zero steady-state error without requiring the complex transformation and the de-coupling technique. Theoretical analyses of both PI and PR controller are presented and verified by simulation and experiment. Both controller are implemented in a 32-bit fixed-point TMS320F2812 DSP processor and evaluated on a 3kW experimental prototype PV Power Conditioning System (PCS). Simulation and experimental results are shown to verify the controller performances.

In order to improve mathematical problem-solving ability, there has been a need for research on practical application of meta-affect which is found to play an important role in problem-solving procedure. In this study, we analyzed the characteristics of the sociodynamical aspects of the meta-affective factor of the successful problem-solving procedure of small groups in the context of collaboration, which is known that it overcomes difficulties in research methods for meta-affect and activates positive meta-affect, and works effectively in actual problem-solving activities. For this purpose, meta-functional type of meta-affect and transact elements of collaboration were identified as the criterion for analysis. This study grasps the characteristics about sociodynamical function of meta-affect that results in successful problem solving by observing and analyzing the case of the transact structure associated with the meta-functional type of meta-affect appearing in actual episode unit of the collaborative mathematical problem-solving activity of elementary school students. The results of this study suggest that it provides practical implications for the implementation of teaching and learning methods of successful mathematical problem solving in the aspect of affective-sociodynamics.

The purpose of this study is to see if we can predict the health of seniors of community by analyzing the connection between social network degree and mental and physical health of old people who live in the areas of Gangwha Island. The subjects of the study were men and women aged 65 or over, a total of 643 that resided in Ganghwa A-county. The survey was conducted on Korean Social Life, Health and Aging Project from the year 2011 to 2012. Regression analysis was carried out using the data. The analysis results were as follows. First, it showed the relationships between income, gender, age out of demographic variables used as control variable and old persons'physical health. The research results showed that physical health was better in case of the higher incomes, men, and lower age. Second, out of demographic variables, educational background, income, age was shown to correlate with mental health. The research results showed that mental health was better in case of the higher incomes, higher educational background, and lower age. Third, in social network including direction, both out-degree and in-degree were shown to predict old people's physical and mental health. The results of this study suggest that not only out-degree but also in-degree should be considered in predicting the health of elderly persons by a person's human relationship. Also, two indicators of degree are meaningful in the dimension of health promotion and welfare of the old in that they can be used for finding isolated individuals that can be physically and mentally vulnerable.

Analysis and sharing of spatial information can be made possible through the reuse of spatial analysis processes, and the sharing of spatial models on the web. However, the deployment of spatial analysis models is possible, only when the difficult tasks of model design and the exchange of spatial data are overcome. In this study, a WPS spatial analysis model is defined, based on the OGC standards, and applied to the 'Selection of Housing Units for Water Supply' application. BPEL was used to define the sequence of processes and to enable the exchange of spatial data. To this end, WSDL was defined for WPS and WFS accesses, the sequence of spatial processes was defined in BPEL, and XSLT was defined for the exchange of XML data. The WPS model was designed and deployed using the Apache ODE which provides RESTful binding. It is expected that effective decision making will be easier using the web based spatial analysis models which are realized by WPS Orchestration with BPEL, as presented in this study.

Traditional landscape is a cultural asset left by Seonhyeon to modern society, and it can not only understand the landscape culture of ancient tradition but also provides / provided a new creative material for modern landscape designs / designed. However, it is well known that Korea and China have a relationship between the development and exchange of landscaping in a global background, the succession of traditional landscape architecture culture in a global background covers many dimensions, including protection, development and innovation, and that "traditional and modern" and "regionally and internationality" should be harmonized with each other. This study uses traditional Korean and Chinese landscaping buildings as research subjects to extract and organize related data through various channels, including basic literature research that understands the history and culture of the two countries. I interpreted the cultural backgrounds of the two countries by dividing them into religious ideas, traditional culture, and natural views, and highlighted the history of development and the relationship between the two countries. Based on this, it analyzed the differences created by traditional landscaping between Korea and China, and also specifically analyzed the "creation of righteous army" and "the law of righteous army." In particular, this study sought to inherit and innovate traditional landscape culture for the internationalization of "One Belt, One Road" based on the characteristics of Korea and China's landscape through a comparative analysis of the construction elements and methods of Yihwawon of the Ming and Qing periods and Gyeongbokgung Palace of the Joseon Dynasty on the theoretical background of landscaping and the significance of landscaping. The direction for the development and exchange with landscaping between the two countries was presented in line with the development trend of Korea-China landscaping in the global environment. In the future, the development of landscaping between the two countries is expected to be key to international cooperation in traditional culture, creative combination of local characteristics, creation of a harmonious landscape architecture environment, and co-prosperity of various cultures.

This study is a case study to identify the spatial composition and structural problems of existing schools for spatial innovation as a future school that can operate a credit system for old high schools and establish a mid-to-long-term arrangement plan as a credit system operating school capable of various teaching and learning in the future. The study results are as follows: First, most of the problems of the old high schools entailed that there was very poor connectivity between buildings as most of them were arranged in a single, standard design-type unit building and distributed in multiple buildings. In addition, the floor plan of each building is suggested to be a structure in which student exchange and rest functions cannot be achieved during the break period due to the spatial composition of the classroom and hallway concepts. Second, in the direction of the high school space configuration for future school space innovation, the arrangement plan should be established by reflecting the collective arrangement in consideration of the shortening of the movement route and the expansion of subject areas due to the movement of students on the premise of the subject classroom system. Moreover, it is desirable to provide a square-type space for rest and exchange in the central area where communication and exchange are possible according to the moving class. Third, as the evaluation criteria for relocating old high schools, a space program is prepared based on the number of classes in the future, and legal analysis of school land use and land use efficiency analysis considering regional characteristics are conducted. Based on such analysis data, mid-to-long-term land use plans and space arrangement plans for the entire school space such as the school facility complex are established.

소련과 동구라파의 개방과 개혁으로 신문지상에는 냉전의 종식, 동서화합 등에 관한 기사가 심심치 않게 등장하며, 잇따른 미$\cdot$소의 군비감축 발표로 정치적으로나 사회적으로나 세계평화가 구가되는 시기가 도래한 듯한 느낌을 준다. 이러한 변화를 일각에서는 민주주의의 승리라고 말하고 있지만, 구체적으로 분석해보면 동구권의 개방고 개혁은 소비재 경제의 파탄으로 서방국가에 비해 국민 생활이 극심하게 낙후된것에 기인하고 있고, 그 원인은 기술의 상업화가 부재하였기 때문으로 서방과 동구의 현격한 민수용 기술격차가 동구권 변화의 근본적 이유이다. 오늘날 기술경쟁은 총성없는 전쟁으로 묘사되고 있으며, 기술정보는 군사정보 이상으로 중요하게 취급되고 있다. 우리는 상재국가 또는 경쟁기업을 대상으로 한 기술전쟁의 시대에 살고 잇다. 얼마나 우수한 물건을 저렴한 가격으로 생산해서 판매할 것인가 하는 문제가 기업의 생존과 그 나라의 경제를 좌우한다고 해도 과언이 아니다. 소련과의 기계기술 교류는 국내의 취약한 기계 기반기술을 고도화 시키고 부가가치가 큰 첨단 기계기술 분야를 국내 토착화 시킬 수 있는 좋은 기회로서 국내 기술계의 역량을 모아 합심해서 대처해야 할 것이다.

국내외의 방송환경의 변화는 외부적으로는 방송의 다매체 다채널 시대로의 변화와 총체적 경기불황으로 방송사 수입이 격감하고 있고, 내부적으로는 고비용 저효율로 방송사 경영의 어려움을 겪고 있다. 이러한 위기의 극복은 방송사 정보화 기반을 구축하여, 방송업무 프로세스를 BPR 하고, 방송CALS의 개념을 도입하여 방송사 내부의 경영혁신으로 이룰 수 있다. 본 논문은 방송장비 보수유지 프로세스의 리엔지니어링을 위하여 방송CALS의 요소인 전자교범(IETM)을 구현함으로써 저비용 고효율형의 방송장비 보수유지를 통한 방송경영 합리화의 실현을 도모함을 목적으로 하며, 기존 23단계의 방송유지 보수유지 업무 프로세스를 전자교범(IETM)을 도입하여 6단계로 개선된 모델을 제시하고, 설문지를 통한 실증 분석한 결과, 전자교범(IETM)을 이용한 방법이 모든 면에서 혁신적으로 개선된 것으로 나타났다. 본 연구의 궁극적인 목표는 방송CALS의 구현이다. 진정한 의미의 방송CALS란, 방송사 내부의 디지털화뿐만 아니라 다양한 외부기관들(프로그램 외주업체, 장비공급자, 국내외의 언론사 등)과의 네트워킹을 통한 멀티미디어 정보의 실시간 교류 및 전자 상거래를 뜻한다. 그러나 본 논문은 방송사 정보화 기반구조의 미흡과 국내 IT기술의 한계로 방송CALS를 포괄적으로 다루지는 못하였지만, 방송CALS의 궁극적인 목적에 도달하기 위한 첫 번째 시도이다.
