This research is aimed to proposing a player evaluation model that can be used in the field by analyzing actual game and applying the data based on methodology to evaluate the performance of soccer players. For this purpose, the following result are obtained by applying the factors and weights shown in the research conclusion of Hong Sung-jin (2017) to actual analysis data. First, the difference analysis results by each position for attack power (score, assist) show differences in scoring, not in assists. Assist can be seen as contributing to scoring in all different positions, regardless of position. Second, the analysis of differences in positions about basic skills (shooting, passing, and dribbling) all shows statistical differences. The post-verification test show no differences between a forward and a midfielder in shooting. In other words, a forward and midfielder can be considered the same position in shooting. In the pass, the team show up in order as a defender, midfielder, and striker. In dribbling, player tries a lot in order as a striker, midfielder, and defender. Third, the analysis of differences in positions of defense (tackle, interceptor, clearing and block) show statistical differences in tackle, clearing and block, and no difference in intercept. Look at the post-verification test, there are no differences between a forward and a midfielder in tackle, clearing and block. In other words, It can be considered as same position. In the meantime, it was concluded that the intercept is working in all positions. Fourth, the analysis of the difference by position in contribution (air ball competition, secondary ball acquisition) showed a statistical difference in the air ball competition, and the second ball has no difference. In particular, the midfielders were the lowest, strikers trying the most air ball competition. As a result Every position tries to take a second ball. Fifth, after analyzing the total score with applying weights, midfielders show highest score. The score of offense defence occupied highest possesion, followed by the forward. In other words, the team could be analasys that used wingback's overlapping or cross a lot. In terms of basic skill, defense, and contribution, midfielders all conclude high scores. It can be seen as the basis for showing the level and importance of midfielders in university football. 이 연구는 축구 선수의 포지션별 차이를 규명하고 가중치 적용을 위한 방법론을 토대로 선수평가 모델을 제시하는데 목적이 있다. 이를 위해 홍성진과 이기봉(2017)의 연구결과에 나타난 요인과 가중치를 실제 분석데이터에 적용하여 다음과 같은 결론을 얻었다. 첫째, 공격력(득점, 도움)에 대한 포지션별 차이분석 결과는 득점에서 차이가 나타났으며, 도움에서는 나타나지 않았다. 도움은 포지션에 상관없이 다양하게 모든 위치에서 득점에 기여할 수 있다고 볼 수 있다. 둘째, 기본능력(슈팅, 패스, 드리블)에 대한 포지션별 차이 분석 결과 모두 통계적 차이가 나타났다. 사후검증을 살펴보면 슈팅에서 공격수와 미드필더의 차이가 나타나지 않았다. 즉, 공격수와 미드필더는 슈팅에 있어 같은 포지션이라고 봐도 된다는 것이다. 패스에서는 수비수, 미드필더, 공격수 순으로 나타났다. 드리블에서는 공격수, 미드필더, 수비수 순으로 많이 시도하는 것으로 나타났다. 셋째, 수비력(태클, 인터셉터, 클리어링, 블락)에 대한 포지션별 차이분석 결과는 태클, 클리어링, 블락에서 통계적 차이를 보였으며, 인터셉터는 차이가 나타나지 않았다. 사후검증을 살펴보면 태클, 클리어링, 블락에서 공격수와 미드필더는 차이가 없었다. 즉 이 요인에서는 같은 포지션으로 봐도 된다는 것이다. 한편 인터셉터는 모든 포지션에 걸쳐 노력하고 있다는 결론을 얻었다. 넷째, 기여도(공중볼경합, 세컨볼획득)에 대한 포지션별 차이분석 결과 공중볼경합에서 통계적 차이를 보였으며, 세컨볼획득은 차이가 나타나지 않았다. 특히, 공중볼 경합은 공격수가 가장 많이 시도하는 것으로 나타났으며, 미드필더가 가장 낮았다. 세컨볼은 전 포지션이 같이 노력한다는 결과로 보여진다. 다섯째, 가중치를 적용하여 총점을 분석해본 결과 미드필더들이 높은 점수를 보였다. 공격력의 점수에서는 수비수 가장 높게 나타났으며, 다음으로 공격수 순으로 나타났다. 즉, 이 팀은 윙백의 오버래핑이나 크로스를 많이 활용하는 팀으로 볼 수 있었다. 기본능력, 수비력, 기여도에서는 모두 미드필더들의 점수가 높은 분포를 보였다. 이는 대학축구에서 미드필더들의 활동량과 중요성을 나타내는 근거로 볼 수 있다.

Phase stabilized leucite, which has high coefficient of thermal expansion, was synthesized, and its thermal expansion behavior was investigated. The homogeneous leucite phase was synthesized by solid state reaction from the mixture of $K_2CO_3-Al_2O_3-SiO_2$. and its stabilization from tetragonal to cubic phase was attempted by adding $Cs_2CO_3$ into starting materials. And fine powder with an average particle size of a few hundreds ${\mu}m$ were fabricated by planetary milling. During milling, amorphization of leucite was observed and recrystallized after heat treatment. The thermal expansion behavior of tetragonal and cubic leucite has measured and discussed. The average coefficient of thermal expansion of tetragonal and cubic phase leucite from room temperature to $750^{\circ}C$ was $21.4{\times}10^{-6}/^{\circ}C$ and $14.5{\times}10^{-6}/^{\circ}C$, respectively.

The prognosis for patients with primary central nervous system (CNS) lymphoma (PCNSL) who relapse after the initial response is usually poor. A standard treatment for relapsed PCNSL has not yet been identified because of the heterogeneity of the therapies employed and the lack of large, prospective clinical trials. We describe a 46-year-old relapsed PCNSL patient who was successfully treated with intraventricular applications of rituximab to minimize neurotoxicity, 2 cycles of salvage chemotherapy with etoposide, ifosfamide, and cytarabine (VIA) regimen and high-dose chemotherapy with autologous stem cell rescue. The high-dose chemotherapy consisted of bischloroethylnitrosourea, etoposide, cytarabine, and melphalan (BEAM) regimen. Partial remission was detected after intraventricular rituximab therapy and the patient has been in complete remission without evidence of neurotoxicity for 28 months after high-dose chemotherapy with autologous stem cell rescue. This case indicates a new appropriate treatment guideline in relapsed PCNSL patient after initial intensive chemo-radiotherapy.

Objective : Melanin is one of the most important facor in skin color. Melanin protects human skin from ultraviolet radiation otherwise it causes melanin pigmentation. So this experiment is carried out for test whether Scutellaria baicalensis Georgi(SBG) inhibits melanin synthesis and tyrosinase activity in mouse B16 melanoma cells. Method : The melanin synthesis inhibition effects of SBG were examined by in vitro melanin production assay. We assessed inhibitory effects of SBG on melanin contents from B16F1 melanoma cell, on tyrosinase activity(cell and cell free system), effect of SBG on the expression tyrosinase, Microphthalmia-associated Transcription Factor(MITF), Extracellular signal-regulated Kinase(ERK). Result : SBG inhibited melanin synthesis induced $\alpha$-MSH($\alpha$-Melanin Stimulating Hormone) in B16F1. SBG inhibited tyrosinase activity and expression. And SBG down-regulates MITF and stimulated ERK activation in B16F1. Conclusion : According to above results, SBG was improved its suppression effect to the inhibition of melanin synthesis, tyrosinase activation, and tyrosinase promotor activation. So SBG is considered to be used for an strong source of skin whitening effect.
