Social problems, such as economic instability, aging population, heightened competition, and changes in personal values, might become more serious in the near future. Affective computing has received much attention in the scholarly community as a possible solution to potential social problems. Accordingly, we examined domestic and global knowledge structure, major keywords, current research status, international research collaboration, and network for each major keyword, focusing on keywords related to affective computing. We searched for articles on a specialized academic database (Scopus) using major keywords and carried out bibliometric and network analyses. We found that China and the United States (U.S.) have been active in producing knowledge on affective computing, whereas South Korea lags well behind at around 10%. Major keywords surrounding affective computing include computing, processing, affective analysis, research, user modeling categorizing recognitions, and psychological analysis. In terms of international research collaboration structure, China and the U.S. form the largest cluster, whereas other countries like the United Kingdom, Germany, Switzerland, Spain, and Canada have been strong collaborators as well. Contrastingly, South Korea's research has not been diverse and has not been very successful in producing research outcomes. For the advancement of affective computing research in South Korea, the present study suggests strengthening international collaboration with major countries, including the U.S. and China and diversifying its research partners.

Understanding the nature of science (NOS) has been a major component of scientific literacy and an important learning goal in science education (American Association for the Advancement of Science, 1990, 1993; Millar & Osborne, 1998; National Research Council, 1996, 2013). To achieve this goal, it is necessary to include appropriate views of the nature of science in science curriculum such as a textbook. The aim of this study was to conduct a content analysis of the elementary science textbooks to examine the presentation of the nature of science (NOS) using the four themes of scientific literacy, which are (1) nature of scientific knowledge, (2) nature of scientific inquiry, (3) nature of scientific thinking, and (4) nature of interactions among science, technology, and society (STS). Findings show while $3^{rd}$ and $4^{th}$ grade levels of science textbooks heavily emphasize on the Theme I, nature of scientific knowledge and the Theme II, the nature of scientific inquiry, the upper grade levels such as $5^{th}$ and $6^{th}$ grades of science textbooks are well balanced with the four themes of the nature of science. In addition, most of elementary science textbooks little focus on the Theme IV, nature of interactions among science, technology, and society (STS) among the four themes of the nature of science. It might be a shortcoming because the understanding the nature of interacions among science, technology and society (STS) is one of the key components in order for students to be a scientific literate person.

Objective: A national survey was conducted to assess orthodontic residents' current concepts and knowledge of cleft lip and palate (CLP) management in Korea. Methods: A questionnaire consisting of 7 categories and 36 question items was distributed to 16 senior chief residents of orthodontic department at 11 dental university hospitals and 5 medical university hospitals in Korea. All respondents completed the questionnaires and returned them. Results: All of the respondents reported that they belonged to an interdisciplinary team. Nineteen percent indicated that they use presurgical infant orthopedic (PSIO) appliances. The percentage of respondents who reported they were 'unsure' about the methods about for cleft repair operation method was relatively high. Eighty-six percent reported that the orthodontic treatment was started at the deciduous or mixed dentition. Various answers were given regarding the amount of maxillary expansion for alveolar bone graft and the estimates of spontaneous or forced eruption of the upper canine. Sixty-seven percent reported use of a rapid maxillary expansion appliance as an anchorage device for maxillary protraction with a facemask. There was consensus among respondents regarding daily wearing time, duration of treatment, and amount of orthopedic force. Various estimates were given for the relapse percentage after maxillary advancement distraction osteogenesis (MADO). Most respondents did not have sufficient experience with MADO. Conclusions: These findings suggest that education about the concepts and methods of PSIO and surgical repair, consensus regarding orthodontic management protocols, and additional MADO experience are needed in order to improve the quality of CLP management in Korean orthodontic residents.

Background: There has recently been a rapid increase in the number of pain clinics and significant advancement in the treatment of pain in Korea. Therefore, this study was conducted to identify possible problems associated with pain clinics and to use this information to help design future pain clinics. This assessment was conducted from the perspective of professional ballet dancers, who are at high risk for pain like other athletes. Methods: One-hundred professional ballet dancers responded to questionnaires designed to ascertain their preference for different types of clinics, the extent of the pain they experience, and their overall opinion of pain clinics. Results: All of the respondents complained of pain in one or more sites and reported that they had visited some type of clinic for treatment at least once. Overall, the respondents preferred using the following methods to treat pain: orthopedic surgery (76 dancers), oriental medicine (49 dancers), and therapy at pain clinic (48 dancers). Fifty-three percent of the 48 dancers who had received treatment at pain clinics were satisfied with their treatment. Forty-four percent of the 52 dancers who had not been treated at a pain clinic had no knowledge of the existence of such facilities. Conclusions: This survey revealed that, although professional ballet dancers have a high prevalence of pain, many have no knowledge of pain clinics. Therefore, efforts should be made by pain clinics to make information regarding their facilities widely available to professional ballet dancers so they can serve the widest range of clientele.

The Korean miracle of economic growth or development has been quite well known across the world up to now, while being subject to theorization of its model. Compared with this, however, it is quite surprising to see how little about the spatial aspect of Korean development has been exposed in the field of development studies. In fact, for Korea, competent regional policy has turned out to be an important success factor for the spatial upgrading of a low-tech growth regime into a hi-tech one. This paper dissects Korea's regional policy experiences in three aspects from which it draws up a three-tier lesson. The first aspect is the conventional (overall) regional spatial upgrading policy of a developmental regime put in place since the 1960s onwards. The second is the new regional policy tailored to the regionalization of technological and industrial diffusion for new knowledge-based economy. The third is the prospective regional policy for the future advancement of the Korean economy.

Nowadays, we are standing in front of the $4^{th}$ Industrial Revolution that is featured by a great range of new and advanced technologies that influences all the domains of economies and industries. The great question that this revolution raises is how it can lead to a future that reflects the peoples' common objectives and values on how these advanced technologies can affect the life and transform the economic, social, cultural, and human environment. It is commonly agreed that to be adapted to these changes and needs and shape a society with competitive economies with highly-skilled individuals, we need to encourage innovation, entrepreneurship, new knowledge generation and exchange and true and effective collaboration and communication. In this complex scene, education seems to have a central and critical role on finding new ways of developing expertise and innovation within the existing knowledge procedures, with more and better cooperation between the key players. This paper argues the concepts, opportunities and challenges that are related to the learning ecosystem towards the needs raised by the $4^{th}$ Industrial Revolution. The education is discussed as catalyst but also as carrier of innovation and innovation practices and the basis of a relevant framework is presented that takes into account all the aspects, domains and key players of educational world and interacting domains. Having introduced the ideas of innovation, collaboration and technology advancement in this environment, this paper also presents a real case of practice, focusing on how more than 5.000 schools around Europe succeeded the last four (4) years to implement innovation activities in a collaborative way and under a unique but also flexible pedagogical innovation framework.

With the advancement of information technology and increasing diversity in medical field, there are ongoing researches on ontology based intelligent medical system in Oriental medicine field. Intelligent diagnostic support system uses ontology to give a structure to complex medical knowledge and personal medical history so that we can make diagnosis more scientific, and provide better medical services. In this paper, we suggest an ontology that structuralize three knowledge types basic medical data, clinical trial data, and personal health information, which can be used as important information for individually tailored diagnosis. Especially in Oriental medicine diagnosis, both patient's symptoms of illness and physical constitution play a great role; it can lead to distinct diagnosis depending on their combination. Thus, it is much needed to have a diagnostic support system that uses personal health history and physical constitution along with basic medical data and clinical trial data in the field. In this paper, we implemented an Oriental medicine diagnostic support system that provides individualized diagnosis service to each patient by building an ontology on Oriental medicine focused on individual physical constitution and disease information.
