Due to the paradigm of open science and advanced digital information technology, data sharing and re-use have been actively conducted and considered data-intensive in a wide variety of disciplines. This study aims to investigate the intellectual structure portrayed by the research products re-using the data sets from ICPSR. For the purpose of this study, a total of 570 research products published in 2017 from the ICPSR site were collected and analyzed in two folds. First, the authors and publications of those research products were analyzed in order to show the trends of research using ICPSR data. Authors tend to be affiliated with university or research institute in the United States. The subject areas of journals are recognized into Social Sciences, Health, and Psychology. In addition, a network with clustering analysis was conducted with using co-word occurrence from the titles of the research products. The results show that there are 12 clusters, mental health, tabocco effect, disorder in school, childhood, and adolescence, sexual risk, child injuries, physical activity, violent behavior, survey, family role, women, problem behavior, gender differences in research areas. The structure portrayed by ICPSR data re-uses demonstrates that substantial number of studies in Medicine have been conducted with a perspective of social sciences.

In sensor networks, because sensors are deployed in an unprotected environment, they are prone to be targets of compromise attack, If the number of compromised nodes increases considerably, the key management in the network is paralyzed. In particular, compromise of Cluster Heads (CHs) in clustered sensor networks is much more threatening than that of normalsensors. Recently, rekeying schemes which update the exposed keys using the keys unknown to the compromised nodes are emerging. However, they cause some security and efficiency problems such as single group key employment in a cluster, passive eviction of compromised nodes, and excessive communication and computation overhead. In this paper, we present a proactive rekeying scheme using renewals of duster organization for clustered sensor networks. In the proposed scheme, each sensor establishes individual keys with neighbors at network boot-up time, and these keys are employed for later transmissions between sensors and their CH. By the periodic cluster reorganization, the compromised nodes are expelled from network and the individual keys employed in a cluster are changed continuously. Besides, newly elected CHs securely agree a key with sink by informing their members to sink, without exchangingany keying materials. The simulation results shows that the proposed scheme remarkably improves the confidentiality and integrity of data in spite of the increase of compromised nodes. Also, they show that the proposed scheme exploits the precious energy resource more efficiently than SHELL.

In modern society, cultural heritage has played a role in constituting national identity. The Cultural Heritage Education Project started in the 2000s by the Cultural Heritage Administration was also aware of the issue of sustainable development and cultural diversity as major cultural issues at the time. However, the main purpose of previous cultural heritage education was to foster national identity. The Cultural Heritage Administration has executed cultural heritage education programs since 2006. The education program of the cultural heritage teacher visiting the school, the project to designate a cultural heritage school, and an education program to experience cultural heritage at an archaeological site were carried out. In the 2010s, the theme of cultural rights and enjoyment of cultural heritage in life was raised as an important issue. Cultural heritage education had to accept the 'new meaning of cultural heritage', 'cultural rights', and 'learnercentered education'. In this context, the local cultural heritage education project started. The region is a space where various identities are reconstructed. However, local cultural heritage education itself cannot realize cultural heritage enjoyment in life. Therefore, it is necessary to seek cultural heritage in life through the various efforts of local cultural heritage education.

This study aims to suggest the academic roles and direction of the social welfare for the elderly in Journal of the Korean Gerontological Society. For this purpose the trends of research on the social welfare for the elderly were analyzed by means of reviewing articles published from 1980 to 2008 in Journal of the Korean Gerontological Society. Out of all published articles, 215 articles were selected on the basis of unanimity among 3 reviewers including this author. First, in 1980s there were very limited numbers of articles. It had been mainly introduced foreign and domestic institutions of social welfare for the elderly and focused on the serious issues for the elderly in aging society. Secondly, in 1990s, there were explosive increases of research in elder welfare studies. The subjects of the articles were diversified and research methods were sophisticated in this period. Thirdly, it showed that the numbers, subjects, and research methods of the articles concerning social welfare for the elderly were enriched and differentiated during 2000-2004. Lastly, the research trends have focused on the issues of successful aging, quality of life, and psychological well-being in consideration of the quality of life for the elderly up to now since 2005. But the research trends have had some limitations in showing only application of theories and models or in simply introducing the knowledge in Western countries. It is necessary to have clear academic identity which can be faithful to Korean Gerontological studies.

This article aimed to looked back at the 1960s, which were assessed to be 'the age of essays', to survey denotations of essays, amplified by the discourse antagonism surrounding 'essays' and the writings of philosophers. Kim Hyeong Suk, Ahn Byeong Uk, and Kim Te Gil were philosophy professors of Yonsei University, Soongshil University, and Seoul National University and writers of numerous essay collections of the 1960s. However, there have been very few studies conducted on them. This is because of old prejudices within literary history that primarily undervalue essays and practices that try to limit them as 'Literariness'. Essays of the 1960s became the flavor of the times based on democratic demands that attempted to objectify individual experiences and grounds that passed through the war and the April 19 Revolution. The language of philosophers was expropriated through the various senses of first person writing to readers of the times, which lacked civil culture and national morality. Deficits in public spheres of the 1950s and 1960s were filled by Kim Hyeong Suk's narrations of comfort and conquest based on historic experiences, Ahn Byeong Uk's logic of self-discipline and knowledge based on democracy, and Kim Te Gil's humor and introspection that objectified the lives of the petit bourgeois. However, as the essays of philosophers failed to connect with the public discourse of the age, they were unable to go as far as sparking or serving as a medium for civil culture in the 1970s. Regardless, as essays rose historically in the 1960s, thought was given to the characteristics of the 'essay' genre and in connection, to the merits and demerits of cultural history that possesses the language of philosophers.

As an emerging power generation technology, triboelectric nanogenerators (TENGs) have received increasing attention due to their boundless promise in energy harvesting and self-powered sensing applications. The recent rise of soft robotics has sparked widespread enthusiasm for developing flexible and soft sensors and actuators. TENGs have been regarded as promising power sources for driving actuators and self-powered sensors, providing a unique approach for the development of soft robots with soft sensors and actuators. In this review, TENG-based soft robots with different morphologies and different functions are introduced. Among them, the design of biomimetic soft robots that imitate the structure, surface morphology, material properties, and sensing/generating mechanisms of nature has greatly benefited in improving the performance of TENGs. In addition, various bionic soft robots have been well improved compared to previous driving methods due to the simple structure, self-powering characteristics, and tunable output of TENGs. Furthermore, we provide a comprehensive review of various studies within specific areas of TENG-enabled soft robotics applications. We first explore various recently developed TENG-based soft robots and a comparative analysis of various device structures, surface morphologies, and nature-inspired materials, and the resulting improvements in TENG performance. Various ubiquitous sensing principles and generation mechanisms used in nature and their analogous artificial TENG designs are demonstrated. Finally, biomimetic applications of TENG enabled in tactile displays as well as in wearable devices, artificial electronic skin and other devices are discussed. System designs, challenges and prospects of TENGs-based sensing and actuation devices in the practical application of soft robotics are analyzed.

In the post-industrial society, concerns about the body have devoted to extend the concept of body from its physical level to the spiritual and corporeal level. Now body is not only an instrument which expresses one's personal character, but also an abstract concept which shows one's identity. Through this tendency, body image as a representation becomes notable as much as physical body itself. This tendency has been exaggerated especially for women and the socio-cultural common notion is forcing them to internalize it by presenting several stereotypes of body image. The concept of body image, a rising academic subject becoming a socio-cultural matter of interest, bears an epistemological base about spirit, body, and individual/social character. As the discussion about body develops in the field of women's studies, deepened discussions about body image are in progress. In this article interaction between the making of stereotypes of the female body in the socio-cultural circumstance and the process of internalization of these stereotypes is analyzed. For the analysis, the hypothesis was established that this interaction constructs the making process of body image. The analyzed materials are images and texts for advertisements, and other materials for public relations which are posted on the homepage of body-line consulting company M. The results of this analysis are to summarize as follows; the stereotypes of the female body image in Korea are very similar to those of westerners, and male gaze plays a big role in the construction of female body image through the internationalization of the gaze by women. According to these results, it is necessary to consider the effort that women should strive to produce and to develop healthy female body images.

With the era of the Fourth Industrial Revolution in sight, innovative business models utilizing new technologies are emerging, and startups are enjoying an abundance of opportunities based on the agility to respond to disruptive innovations and the opening to new technologies. However, what is most important in creating a sustainable start-up ecosystem is not the start-up itself, but the process of research-start-investment-investment-the leap to listing and big business-in order to build a virtuous circle of startups that leads to re-investment. To this end, the environment created in the hub area where start-ups were conducted is important, and these material and non-material environmental factors are described as being inclusive by the word "entrepreneurial ecosystem." This study aims to provide implications for Korea's entrepreneurial ecosystem through the study of the interaction of the elements that make up the start-up ecosystem and the relationship of ecosystem participants in Singapore. Singapore has been consistently mentioned as the top two Asian countries in assessing the start-up environment and business environment. In this process, six elements of the entrepreneurial ecosystem presented by Isenberg(2010)-policies, finance, culture, support, human resources, and market-are the best frameworks for analyzing entrepreneurial ecosystems in terms of well encompassing prior studies related to entrepreneurial ecosystem elements, and a model of regional transformation is formed focusing on some elements to suit Singapore, the target area of study. By considering that Singapore's political nature would inevitably have a huge impact on finance, Smart Nation policy was having an impact on university education related to entrepreneurship, and that the entrepreneurial networks and global connectivity formed within Singapore's start-up infrastructure had a significant impact on Singapore's start-up's performance, researches needed to look more at the factors of policy, culture and market. In addition, qualitative research of participants in the entrepreneurial ecosystem was essential to understand the internal interaction of the elements of the start-up ecosystem, so the semi-structured survey was conducted by visiting the site. As such, this study examined the status of the local entrepreneurial ecosystem based on qualitative research focused on policies, culture and market elements of Singapore's start-up ecosystem, and intended to provide implications for regulations related to start-ups, the role of universities and start-up infrastructure through comparison with Korea. This could contribute not only to the future research of the start-up ecosystem, but also to the creation of a start-up infrastructure, boosting the start-up ecosystem, and the establishment of the orientation of the start-up education in universities.

As of end of 2014, the population engaging in aviation activities for leisure has reached approximately 13 million, where approximately 356 cases involve a general aircraft, 200 cases involve light aircraft, and 636 cases involve an ULM. The industry for leisure has become a very promising industry in line with rapidly rising living standards which are expected to further increase in the future. The demand for such services is expected to increase over time. The purpose of this paper is to review the development and site selection of airfields in anticipation of these developments in the industry. While the government also has experience in the review of airfield location and candidate sites, it is not the government that carries out the actual construction. As such, the feasibility of the site needs to be verified in terms of actual construction. This study identified factors for Site Selection of factors through a review of related documents and existing research reports. A questionnaire was also used to collect the views of experts in the field, which was then analyzed. The Research model was confirmed in the layered form for an AHP analysis. The factors for Site Selection were identified as the technical / operational factors and economic / political elements for a two-stage configuration. The third step consisted of technical and operational elements. The final step is was constructed a total of 11 elements (weather, surface conditions, obstacle limitation surface, airspace conditions, operating procedures, noise problems, environmental issues, availability of facilities, construction and investment costs, contribution to the local economy, accessibility, demand / the proximity of demand). The surveys are conducted for more than 10 General and light aircraft pilots, professionals, and instructor. The analysis results showed a higher level in the technical / operating elements (73.2%) in the first step, while the next step sawa higher level of the operational elements (30.9%) than the other. The factors for Site Selection were any particular elements did not appear high, the weather conditions (17.5%), noise problems (19.8%), the proximity of demand (6%), accessibility (5.7%), environmental issues (11.1%), availability of facilities (8%), airspace conditions (7.9%), obstacle limitation surface (12%), construction and investment costs (4.2%) and to operating procedures (4.9%), contribution to the local economy (3.8%).

The present study examines the transnational "Hallyu" (the Korean wave) phenomenon after the 1990s in the context of a solidarity movement of East Asian women. It also focuses on the passion for the world stage given the cultural industry was supported by the government as a "chimney-less factory" during the IMF financial crisis. Over the past twenty years and through Hallyu 1.0, Hallyu 2.0, and Hallyu 3.0, "K-entertainment" has been advocated, as a concept that encompasses K-drama, K-pop, etc. in the cultural industry. Furthermore, everything Korean, through K-culture, is being put at the forefront. However, there is insufficient discussion regarding the actions of the women who led the Korean wave. This paper examines the female fans and girl groups who played leading roles in the rise of popular culture and its transnational prominence within the context of the female agency and female labor involved. The lack of acknowledgment of their roles is linked to the current erasure of the discussion on the female youth. Discussion on "woman" is still limited to the domain of reproduction in the generational discussion that has replaced the existing nation-state or class led discussions in the current era of neoliberalism. However, since The reboot or the popularity of feminism in recent years, the interest in the female narrative, in works such as 'Kim Ji-young, Born 1982' has been expanding beyond East Asia to the rest of the world. Just as Hallyu was created by women in the beginning, there is a new trend in which women across national borders are joining in solidarity. As such, the present study attempts to prove that the female fan, girl group, and female youths must be one meta-narrative through a feminist reading, rather than individuals with separate identities.
