We investigated the particularity of temperature and composition changes in $xNa_2O{\cdot}(52.5-x)B_2O_3{\cdot}47.5SiO_2$ glasses by use of FT-IR, $^{11}B$ NMR, Raman spectrometer. From FT-IR and $^{11}B$ NMR spectrometer, we thought that tetrahedral boron, $BO_4$ units are created $N_4$ increasing tendency generated near $600^{\circ}C$. It's expected that composition ana heat treatment directly contributed to structural changes, this changes are following to $Na_2O$ increasing or decreasing. caused by $N_4\;and\;BO_4$ units are caused by relatively increasing or decreasing in the glasses' structure. Particularly, $BO_4$ units are converted to $BO_3$ units after $600^{\circ}C$ heat treatment for 50h in the composition of $x<18(R<0.5,\;R=Na_2O/B_2O_3\;mol\%)$. On the order hand, $BO_3$ units are converted to, $BO_4$ units after $600^{\circ}C$ heat treatment for 50h in the composition of $x{\geq}18\;(R>0.5)$. This particularity of composition and temperature dependence of structural changes are similarly represented by Raman analysis results.

본 연구는 텍스트마이닝과 네트워크 분석을 활용하여 국내 체육사 연구의 지식구조를 도출하고 연구동향을 분석하는데 목적이 있다. 연구범위는 한국체육사학회지의 창간호부터 20년간(1996∼2015) 발표된 논문으로 설정하였다. 연구절차는 논문의 주제키워드를 추출 후 텍스트마이닝과 네트워크 분석을 통해 지식구조를 도출하였다. 분석결과 현대체육사의 지식 구조는 대부분의 주제키워드가 연구영역 구분 없이 긴밀한 관계를 맺고 있는 `좁은 세상 네트워크`형태를 띠고 있는 반면, 과거 시대의 지식구조는 연구영역과 주제키워드 활용이 한정적임을 알 수 있었다. 또한, 지식구조를 통해 연결 관계가 없는 키워드 간 주제접근의 시도와 이를 촉진하는 높은 매개중심성, 근접중심성의 주제키워드를 탐색하는 것은 체육사학 주제영역의 확대를 모색하는 방법 중 하나로 나타났다. 본 연구결과는 정량적 역사연구에서 기대할 수 있는 새로운 시각의 역사적 통찰가능성을 제시하고 있다. 이는 `빅데이터 인문학`적 관점에서 볼 때 분석결과의 의미를 더욱 윤택하게 부여할 수 있는 역사가의 능력과 역할이 더욱 중요해지고 있음을 시사하고 있다. The purpose of this study is to derive the knowledge structure of physical education history and to analyze the research trend by using text mining and network analysis. The range was set up as a paper published for 20years from the first issue of Korean Journal of Physical Education history. The data was extracted from the theses of the thesis and used in the network analysis for deriving knowledge structure through text mining process. As a result of analysis, modern physical education history has a `Small World Network` form in which most keywords are closely related to each other. In addition, it is one of the ways to explore the theme of the theme of the physical education history by searching for the theme of high mediation, proximity. Through this study, it is expected that the possibility of historical insight of new perspectives that can be expected from quantitative history research as well as the expansion of domestic history research can be expected to increase the capacity and role of historian from the perspective of `big data` humanities.

박성제(Seong Je Park),박정현(Jung Hyun Park),류민영(Min-Young Lyu),구명술(Myung Sool Koo),노형진(Hyung Jin Rho),조성환(Sung Hwan Cho) 한국고분자학회 2017 폴리머 Vol.41 No.3

본 연구에서는 fossil PC와 bio-based PC를 이용하여 사출성형으로 제작한 시편에서 bulk 및 weldline 강도와 FDM 방식 3D 프린팅에서의 적층강도를 측정하고 비교하였다. Weldline 강도 시편의 경우 공정온도 증가에 따라 weldline 강도와 파단 시 연신율이 증가하였다. 3D 프린팅으로 적층된 시편의 경우 적층방향 인장 시험에서는 공정온도 증가에 따라 적층강도와 파단 시 연신율의 변화가 미미하였다. 반면, 적층 직각방향의 인장시험에서는 공정온도 증가에 따라 적층강도와 파단 시 연신율이 비례적으로 증가하였다. 3D 프린팅으로 제작한 시편에서 가장 낮은 강도를 보이는 적층 직각방향의 강도는 weldline 강도 대비 각각 62.78%와 25.81%를 보였다. 그리고 3D 프린팅 시편에서 적층방향의 강도 대비 적층 직각방향의 강도의 비는 fossil PC와 bio-based PC에서 각각 69.97%와 51.52%로 나타났다. The deposition strength in FDM type 3D printing-manufactured specimen and the bulk and weldline strength in a specimen prepared by injection molding using fossil PCs and bio-based PCs were measured and compared. In the injection molded specimen, weldline strength and fracture elongation increased with increasing processing temperature. As for the results of the deposition direction tensile test, deposition strength and variation for fracture elongation in the 3D printing-manufactured specimen were marginal with an increase in processing temperature. On the other hand, the orthogonal to deposition direction tensile test revealed that both deposition strength and fracture elongation were proportional to processing temperature. The ratio of weldline strength and the strength in the orthogonal to deposition direction, which presented the lowest strength value in the 3D printing-manufactured specimen, was equivalent to 62.78% and 25.81% in fossil PCs and bio-based PCs, respectively. The ratio of strength in the deposition direction and orthogonal to deposition direction in the 3D printing-manufactured specimen was 69.97% and 51.52% in fossil PCs and bio-based PCs, respectively.

국내 스포츠 사회과학 분야 통합 학술 지식지도(Knowledge Map) 분석

박성제 ( Sung-je Park ),이제욱 ( Jea-woog Lee ) 한국스포츠정책과학원(구 한국스포츠개발원) 2016 체육과학연구 Vol.27 No.3

본 연구는 국내 스포츠 사회과학 학술지의 10년 간 지식구조의 흐름을 살펴보기 위해 스포츠산업경영학회지, 스포츠교육학회지, 스포츠사회학회지, 스포츠심리학회지, 여가레크리에이션 학회지를 대상으로 소셜 네트워크 분석기법 중 커뮤니티 분석을 통해 지식지도를 도출하였다. 분석결과 스포츠 사회과학 분야 통합 지식지도는 5개의 그룹으로 분리되었으며, 각 그룹은 본 연구의 대상인 5개 학술지 연구영역의 주제키워드군의 지식구조와 유사하게 도출되었다. 이러한 결과와 동시에 각 관계마다 차이는 있지만 전체적인 그룹 간 주제키워드의 교류관계를 확인할 수 있었다. 특히, 스포츠산업경영학 연구영역의 주제키워드 중 일부가 여가레크리에이션과 스포츠사회학 연구영역으로 전이되어 있으며, 스포츠사회학은 스포츠산업경영, 스포츠심리학과 밀접한 교류관계를 나타내고 있다. 스포츠심리학은 대부분의 타 그룹과 연결관계를 이루며, 인간행동을 이해하는 심리학적 변인의 넓은 활용성을 확인할 수 있었다. 한편, 여가레크리에이션학 영역은 주로 스포츠심리학, 스포츠경영학 주제키워드와 매우 높은 연구관계를 나타내고 있으나 보다 독자적인 연구 개념의 필요성 또한 시사하고 있다. 스포츠교육학 분야는 특성상 고립되어 있지만 스포츠심리학과의 교류를 이루고 있으며, 체육학 페다고지 개념의 접근을 통한 연구영역의 확대를 모색할 수 있다. To examine the flow of knowledge structure in Korean journals of sport and social sciences over the last 10 years, this study has derived a knowledge map by conducting community analysis, one of the social network analysis methods, on Korean Journal of Sports Industry Management, Korean Journal of Sport Pedagogics, Korean Journal of Sport Sociology, Korean Journal of Sport Psychology and Korean Journal of Leisure and Recreation. According to the analysis result, the integrated knowledge map for the field of sport and social sciences was classified into 5 groups and these groups were derived to be similar to the knowledge structure of the keyword groups for the research topics of the five journals targeted by this study. Along with this result, at the same time, it has been confirmed that most of the groups shared keywords with each other. Especially, some of the keywords for the research topics of sports industry management have transferred to the research topics of leisure and recreation and those of sport sociology. Sport sociology has been revealed to be closely related to sports industry management and sport psychology. In the case of sport psychology, it has been confirmed that it is related to most of the other groups and the psychological variables for understanding human behavior can be widely used. It shows that leisure and recreation is highly related to sport psychology and sport management in terms of keywords for research topics but it is suggested that it also needs its own independent research topics. Sport pedagogics, by its nature, is an isolated field but interacts with sport psychology and attempts can be made to expand its research topics through an approach based on the concept of pedagogy for physical education.

스포츠 공공 빅데이터(Big Data)의 미래 활용가치를 위한 발전방안

From 1990s onward, the level of Korea`s informatization has grown at a remarkable speed to a global level, ranking high in various reports by information agencies assessing the e-government and informatization index. Especially, Seoul Metropolitan Government provides public data of all sectors by launching the “Open Data Plaza(data.seoul.go.kr)” where anyone can download data and use it to create various contents(Kim Soodong, 2009). In the area of sports, there have been many efforts to implement new policies and research projects for practical use of informatization. For example, through the promotion of “cultural informatization” by the Ministry of Culture and Tourism, three-stage establishment of comprehensive cultural information system(2001-2010) was carried out. Also, Korea Sport Science Institute is leading the development of contents for informatization of sports, DB search and cyber fitness management system. However, it has been pointed out that these projects have the limit of producing only short-term results due to its near-sighted focus. This is surfaced in the public data in the fields of sports presented by the aforementioned “Seoul Open Data Plaza” which exhibit several problems. Firstly, the lack of identity in the categorization of data is noticeable. Sports public data is categorized not as a stand-alone category but under the “culture and tourism” group. Searching “sport” at the British public data portal “data.gov.uk” yields about 120 results. Not only are there many results available, but they are also wide-ranged and interesting. Furthermore, at the initial stage of building the DB for the “Seoul Open Data Plaza,” the research of “social big data” was performed using Twitter(www.twitter). The thousands and millions of personal opinions flowing in the social network naturally expose social big data that presents a demand forecast with more perceptive insights than traditional means of surveys. Demand for sports public data could be surveyed again from a point of view strictly concerning sports which has been relatively neglected so far during the existing processes. The web paradigm of the current information society is to create new values through new services for the gen - eral public and business models using public data, and sports public data should also strengthen its role in fulfilling the right of the public to know and in offering a chance to accumulate new intellectual property.

The present resea rch analyzed the content of 3 kinds of toxic heavy metals such as Mercury, Lead and Cadmium in hair through hair analysis with the target of 60 persons consisting of 30 residents in a coastal region(Taean) and 30 residents in an inland area (Nonsan) in order to find out the effect that the environmental factor due to regional difference affects the content of heavy metals. As a result of analyzing toxic heavy metals according to a region, in the content of Mercury, Lead and Cadmium, a coastal region (Taean) respectively appeared as 1.562±1.084 μg/g, 1.380±1.168 μg/g and 0.035±0.044 μg/ g, and an inland area (Nonsan) respectively appeared as 0.576±0.343 μg/g, 0.731±0.734 μg/g and 0.012±0.016 μg/g, so the Taean region showed a higher content of toxic heavy metals than the Nonsan region. Therefore, the content of Mercury (p<.01), Lead (p<.05) and Cadmium (p<.01) showed a statistically significant difference according to the region. In case of Mercury, 60% of Taean residents and 10% of Nonsan residents appeared as the surplus population, and there was a statistically significant difference. The content of Mercury and Cadmium, men showed 1.393±1.173 μg/g and 0.035±0.046 μg/g respectively. Therefore, men showed a higher content, compared to the Mercury content of 0.744±0.449 μg/g and the Cadmium content of 0.035±0.046 μg/g of women, so the content of Mercury and Cadmium according to the gender showed a statistically significant difference (p<.01). As a result of age analysis, it appeared that the older the age range is, the higher the content of Mercury, Lead and Cadmium is, and there wasn`t a statistically significant difference. As a result, We figured out that the coastal area, Taean, has higher risk in exposure to toxic heavy metals than the inland area, Nonsan, regarding the effect of environmental factor in heavy metal contains in hair due to the regional differences.

Social Network Analysis was first introduced in Korea during 1980’s and has been used in many studies as the tool to identify the properties of the human networks. Since then, many researchers in Korea and other countries adjusted and upgraded the social network analysis method, which is gaining more and more attention as the advance of Bid Data concept and the need for an advanced technology to analyze the characteristics of data of large volume and high variety. As such, the ever-evolving social network analysis technology has been adopted by the academic field and utilized in a variety of applications, while the discipline of sports still repeats the previous methodology. There have been several study attempts, where knowledge maps are established and the game analysis, such as the path connection networks, was used. However, it is still necessary to improve the qualitative level of the sports researchers by more widely introducing such analytical methods and apply/develop analytical techniques that reflect the characteristics of the sports science.
