The purpose of this study was to develop a standardized scale to diagnostic life planning in late adolescence. A preliminary 32 item scale was developed through a literature review & a survey. 896 people responded to an online survey using the preliminary scale. A series of test, such as test-retest, item-to-total correlation, factor analysis and Cronbach' ${\alpha}$ reliability were conducted using the survey data and a scale comprising 31 items was constructed finally. The diagnostic scale for life planning in late Adolescence consisted of seven factors : (1) complete growth minds (2) life- plan (3) variety experiences (4) close relationships (5) management of healthy body (6) practical finance-plans (7) active preparation of future job. The scale is useful as a guideline for managing life of the late Adolescence. And it is helpful to them to make plan for the better life.

With the advancement in the field of image processing, images are being processed using various image processing algorithms. Nowadays, many efficient content-aware image resizing techniques are being used to safeguard the prominent regions and to generate better results that are visually appealing and pleasing while resizing. Advancements in the new display device with varying screen size demands the development of efficient image resizing algorithm. This paper presents a survey on various image retargeting methods, comparison of image retargeting results based on performance, and also exposes the main challenges in image retargeting such as content preservation of important regions, distortion minimization, and improving the efficiency of image retargeting methods. After reviewing literature from researchers it is suggested that the use of the single operator in image retargeting such as scaling, cropping, seam carving, and warping is not sufficient for obtaining satisfactory results, hence it is essential to combine multiple image retargeting operators. This survey is useful for the researchers interested in content-aware image retargeting.

Purpose: The present research was designed to explore a causal relationship among SNS prosumer characteristics, relationship quality, user satisfaction, and loyalty intention, and we intended to explore mediating role of relationship quality in the causal relationship. Methods: As survey tool, questionnaire that had obtained validity and reliability through literature survey and pretest survey, and sample 214 was analyzed using SEM analysis method. Results: All theoretical relationships, except the relationship between information provision and relational quality, proved to be significant. The relationship quality plays an important intermediary role in the research model. Conclusion: The characteristics of SNS prosumer activity can be summarized by interaction and informational provision. To increase user satisfaction and loyalty, it is necessary to support these characteristics and strengthen relationships with customers.

VANET is an upcoming technology with an encouraging prospect as well as great challenges, specifically in its security. This paper intends to survey such probable attacks and the correlating detection mechanisms that are introduced in the literature. Accordingly, administering security and protecting the owner's privacy has become a primary argument in VANETs. To furnish stronger security and preserve privacy, one should recognize the various probable attacks on the network and the essence of their behavior. This paper presents a comprehensive survey on diversified attacks and the recommended unfolding by the various researchers which concentrate on security services and the corresponding countermeasures to make VANET communications more secure.

이 논문에서는 산업체 근무자에 대한 설문조사를 통해 우리나라 공학교육의 문제점을 파악하고자 하였다. 이를 위해 토목공학 분야에 대해서는 공학교육인증원에서 요구하는 학습성과를 기준으로 설문지를 작성한 후 직접 설문조사를 실시하고 그 내용을 분석하였으며, 화학공학 및 전자공학 분야에 대해서는 문헌조사를 통해 확보한 최근의 조사 결과를 이용하여 분석하였다. 설문조사 결과 3개 분야 모두 산업체 요구수준에 비해 대학졸업생의 수준이 절반에도 못 미치는 것으로 나타나 공학교육의 개선이 시급한 것으로 분석되었다.

The purpose of the study was to investigate attitudes toward to, values and expectations of environmental education of Korean students and teachers and to provide basic data and reference materials needed to development of environmental education curricula for primary and secondary schools. A review of the related literature, a series of conferences with teachers and specialists in environmental education and environmental sciences. and questionnaire survey were methods employed in this study. Survey question were developed to explore attitude and responses of primary and secondary school students and teachers on various types of issues and problems of environmental education at personal level as well as on their future prospects attitudes values and expectations with which had been dealt in this study were categorized into personal feeling on environmental issues and problems at both national and regional levels issues and problems of current environmental education pre service and in service training of teachers for environmental education instruction and so on. The sample population for the survey was selected by using the stratified cluster and random sampling techniques with respect to regional area, school level, sex and grade, The subjects used in this study were 1,633 students and 385 teachers of primary and secondary schools across the country. The results of the survey were summed up and recommendations to be considered in the revision of sixth national curricula for primary and secondary schools were also suggested.

Security issue in mobile ad hoc network (MANET) is a promising research. In 2011, we had accomplished a survey of black hole attacks in MANETs. However network technology is changing with each passing day, a vast number of novel schemes and papers have been proposed and published in recent years. In this paper, we survey the literature on malicious attacks in MANETs published during past 5 years, especially the black hole attack. Black hole attacks are classified into non-cooperative and collaborative black hole attacks. Except black hole attacks, other attacks in MANET are also studied, e.g., wormhole and flooding attacks. In addition, we conceive the open issues and future trends of black hole detection and prevention in MANETs based on the survey results of this paper. We summarize these detection schemes with three systematic comparison tables of non-cooperative black hole, collaborative black hole and other attacks, respectively, for a comprehensive survey of attacks in MANETs.

이 논문에서는 한국고전문학을 활용한 체험형 게임 관광프로그램을 개발하고자 하는 과정의 첫 번째 시도로써 중인가객 김수장과 그의 가집 『해동가요』를 대상으로 1차 연구를 진행하였다. 이를 위하여 관광콘텐츠로서 체험형 게임과 한국고전문학의 가치에 대한 이론적 검토를 먼저 진행하였다. 이후 프로그램의 수요층을 가족, MZ 세대 및 연인, 외국인의 세 분류로 설정하였으며, 이들을 대상으로 설문조사를 실시하여 각 수요층의 성격 및 프로그램 선호도를 확인하였다. 이를 바탕으로, 가집 『해동가요』와 김수장이 창작한 7수의 시조 작품에서 분석틀에 따라 각각의 역사문화자원으로서의 주요 가치를 발굴하고, 대상과 관련된 수요층의 선호를 분석하였다. 이에 따라 가족 단위는 모험플롯으로, MZ세대 및 연인의 경우에는 사랑플롯으로, 외국인의 경우에는 모험과 사랑을 혼합한 플롯으로 구성하여 각 수요층에 맞게 서사구조를 차별적으로 조직하였다. 이 글은 스토리텔링적인 가치가 있음에도 불구하고 지금껏 잘 활용되지 못한 한국고전문학, 그 중에서도 김수장이라는 인물과 그의 작품에서 스토리를 발굴하고, 이를 체험형 게임 관광프로그램으로 발전시킴으로써 한국고전문학의 측면에서도, 관광학의 측면에서도 새로운 시도를 해보고자 하였다. 이후로도 다양한 조선의 문학인들을 발굴하여 지속적으로 스토리텔링을 진행한다면 고전 문학 기행 콘셉트의 여행상품군의 활성화를 기대해볼 수 있을 것이다.
