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.

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.

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.

Afferent loop syndrome (ALS) accompanying acute pancreatitis is characterized by abdominal pain, vomiting and elevation of serum amylase. Thus, it is difficult to differentiate ALS from other causes of acute pancreatitis. However, the history of gastrectomy can be an important clue for diagnosing ALS. We experienced two cases of ALS accompanying acute pancreatitis. The laboratory findings of the patients showed elevation of serum amylase and they were initially diagnosed as only acute pancreatitis. However, the diagnosis were modified as ALS with the aid of computed tomography. After appropriate management, the abdominal pain disappeared and serum amylase level decreased. In conclusion, ALS should be considered as a cause of acute pancreatitis in patients who have the elevated level of serum amylase and a history of gastrectomy.

The purpose of this study is to explore the flow of academic status and to establish the Knowledge map of the Keyword retrieved from papers in the ‘Journal of Korean sport psychology’ for 25 years. Research scope included keyword extracted from 520 papers in the area of “Sport Psychology” published in the Journal of ‘Korea Society of Sport Psychology’ from 1990 to 2014. Data pre-processing of extracted keyword was performed by Clustering and Simultaneous emergence matrix. Knowledge map was constructed by Social Network Analysis with extracted data. In this study, data pre-processing of extracted keyword was performed by Clustering and Simultaneous Emergence Matrix. Knowledge Map was constructed by Social Network Analysis with extracted data. We conducted the Word Cloud Analysis by utilizing R statistical package in order to visualize the frequency of subject keywords. We conducted the Centrality Analysis by pattern through Net Miner 4.2 in order to identify subject keyword’s intrinsic function and intellectual structure. We also conducted Community Analysis which is one of the social network analyses, thru Net Miner program in order to derive research area by each period. The results of analysis indicated that the subject keywords and the research concepts that were related to ‘motivation’, ‘emotion’ and ‘personality characteristics’ were playing the major role in sports psychology research. Also in the process of exploring these major theories, we could have an insight on entire research trend of how various psychological theories had newly emerged, declined or changed throughout each period. As a further study, examining research trend with a variety of view by identifying not only theory of paper but also citations and joint studies by authors could be an approach which can strengthen the insight of domestic sport psychology research trends.
