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.

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

박성제(Sung Je Park),이제욱(Je Uk Lee) 한국사회체육학회 2013 한국사회체육학회지 Vol.0 No.54

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.

텍스트마이닝과 네트워크 분석을 통한 한국체육사 연구의 시대별 지적구조 분석

박성제 ( Park Sung-je ),이제욱 ( Lee Jea-woog ) 한국체육사학회 2017 체육사학회지 Vol.22 No.2

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.

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.

ECU 응답특성 분석을 통한 T-50 계열 항공기 보조동력장치 자동꺼짐 개선에 관한 연구

박성제(Sung-Jae Park),유인제(In-Je Yoo),최수진(Su-Jin Choi),이동기(Dong-Ki, Lee) 한국산학기술학회 2017 한국산학기술학회논문지 Vol.18 No.3

T-50 계열 항공기는 비행 전 지상에서 비상동력계통 작동 점검을 위해 보조동력장치 GEN TEST를 수행하게 된다. 만일 GEN TEST 수행 중 비상동력계통에 전원이 정상적으로 공급되지 않을 경우 ECU의 응답 신호를 통해 보조동력장치가 자동으로 꺼지는 현상이 발생하게 되며, 지상에서 비상동력계통 작동 점검이 정상적으로 이루어지지 않을 경우 더 이상 비행을 할 수 없기 때문에 해당 결함은 항공기 가동률 저하에 큰 원인이 된다. ECU에서 식별된 결함코드는 인버터 결함으로 판별되었으나 인버터 교체 이후에도 동일한 결함이 지속적으로 반복되었다. 본 논문은 인버터가 특정 시간 안에 전압을 생성시키지 못 할 경우 ECU에서는 결함으로 식별되는 것이 확인되었으며, 보조/비상동력계통의, BSG, ESC, 및 ECU의 응답특성을 분석하여 개선된 방법을 제시한다. 또한, 개선된 방법에 대한 검증을 통해 비상동력계통 출력 요구시간 범위 안에 인버터 출력이 정상적으로 생성되는 것을 확인하였으며, 이를 통해 비행전 지상에서 GEN TEST 수행 시 보조동력장치 자동 꺼짐 현상을 효과적으로 예방 할 수 있음을 확인 하였다. A GEN TEST of the auxiliary power unit of a T-50 series aircraft is performed as part of the operational test of its emergency power system on the ground before flight. At this time, the auxiliary power unit should be automatically turned off via the response signal of the ECU when power is not normally supplied to the emergency power system. If the correct operation of the emergency power system cannot be confirmed on the ground, it is not possible to proceed with the flight. This kind of defect is a major factor causing the operation rate of the aircraft to be decreased. The defect code identified by the ECU was confirmed as a defect in the inverter. However, the same defect was found after replacing the inverter. This report presents an improved method of identifying the cause of the defect by analyzing the response characteristics of the ECU and emergency power system and allows the ECU to be recognized as the cause of the defect if the inverter does not generate a voltage within a certain time. Also, the application of the improved method confirmed that it can satisfy the output request time of the emergency power system and effectively prevent the auto-shutdown of the auxiliary power unit.

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.

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.

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.
