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.

홍성진,박성곤,김상연,문희섭,박완상,김준수,강성훈,이재훈 韓國臨床獸醫學會 2017 한국임상수의학회지 Vol.34 No.4

An 8-month-old Chow-Chow dog presented with dysphagia and regurgitation, and was diagnosed with cricopharyngeal dysphagia (CPD). Cricopharyngeal myotomy did not improve the clinical signs. Three months after the initial surgery, a subtotal myectomy of cricopharyngeal muscle with partial thyropharngeal myotomy was performed. The clinical improvement was maintained for more than one year after the second surgery. Subtotal myectomy of cricopharyngeal muscle can be considered for dogs with CPD that do not respond to myotomy.

Objective: Chronic otitis media is an inflammation and infection of the middle ear which is persistent. Chronic otitis media occurs when the eustachian tube becomes blocked repeatedly, multiple infections, ear trauma, or swelling of the adenoids. A chronic ear may be the result of an acute ear infection that does not clear completely, or the result of recurrent ear infections. A chronic ear infection may be more destructive than an acute ear infection because its effects are prolonged, and it may cause permanent damage to the ear. Methods : Experimental animals made use of 4-5 weeks age(weight 20-25g) ICR(male)mouse. In the breeding farm, the lighting time was controlled from 7:00 am until 7:00 pm, the temperature was controlled within $22{\pm}0.5{\circ}$ and water and food were not limited. The extracts which were extracted from Hwangginaetak-san devided low dose group( 1.0g/kg-HN) and high dose group(3.0g/kg-HN), they were intragastrically administered to the mouse of sample A and sample B prior to LPS I.P injection. Compared with inflammation induced group which were induced by LPS, we measured the WBC count, IL-6 level in plasma and TNF-${\alpha}$ level in plasma. Results: 1. Hwangginaetak-san decreased WBC count in inflammatory reaction induced by LPS 2. Hwangginaetak-san decreased IL-6 level in inflammatory reaction induced by LPS. 3. Hwangginaetak-san didn't decreased TNF-${\alpha}$ level in inflammatory reaction induced by LPS Conclusion: According to above results, Hwangginaetak-san was improved its suppression effect to the inflammatory reaction through WBC count and IL-6 level. So Hwangginaetak-san is considered to be used for treatment of chronic otitis media by controlling the WBC count and IL-6 level in plasma.

The compression index, which represents the compressibility of clay, is generally obtained from the consolidation test, or has been predicted by empirical correlations with soil properties. In this study, the results of consolidation tests on natural and reconstituted Busan and Inchon clays are analyzed to figure out the sedimentation state and its effect on empirical correlations. Results of analysis show that the void index of Busan clay is higher than SCL while the void index of Inchon clay is lower than SCL. By comparing prediction errors with Δer, which represents the sedimentation state of clay, it is shown that errors predicting the compressibility based on the liquid limit and plasticity index decrease as Δer increases. Supplemented correlations predicting the compression index of Busan and Inchon clays are suggested using these relationships.

상수관망 수리해석을 통한 폭염 저감 시설로써의 소화전 활용방안연구

In this study, a study on how to use a fire hydrant as a heat wave reduction facility through hydraulic analysis of the water supply pipe network was conducted. Assuming that the fire hydrant installation point is open for heat wave reduction, the water pressure at each point was derived. And the reduction rate of the temperature according to the hydrant watering was compared with the watering area according to the operation of the watering truck. The watering area according to the opening of the fire hydrant was calculated by deriving the pressure value at the node where the fire hydrant was installed through hydraulic analysis of the water pipe network, and then using the watering radius relational expression according to the pressure value. As a result of applying the proposed methodology to two real city areas, the temperature reduction effect of the watering method by a fire hydrant can be derived lower than the watering method by a watering truck according to the difference in the absolute watering area. However, unlike a watering truck, a fire hydrant does not have a relative restriction on the amount of water supply and is expected to allows continuous divided spraying of the same area. 본 연구에서는 상수관망 수리해석을 통한 폭염 저감 시설로써의 소화전 활용방안연구를 수행하였다. 소화전 설치 지점을 폭염저감을 위해 개방한다고 가정하고, 지점별 수압에 따른 살수반경을 도출하고 전체 대상구역의 살수면적에 따른 도심지 온도의 저감비율을 살수차운영에 따른 살수면적과 비교하였다. 소화전 개방에 따른 살수면적은, 상수관망 수리해석을 통해 소화전이 설치된 절점에서의 압력값을 도출한후, 압력값에 따른 살수반경 관계식을 통해 산정하였다. 제안된 방법론을 2개의 지역에 적용한 결과, 소화전에 의한 살수방법의 온도저감 효과는 절대적인 살수면적의 차이에 따라, 살수차에 의한 살수방법 대비 낮게 도출될 수 있다는 한계점을 보였다. 그러나, 소화전은 살수차와 달리 물공급양에 대한 상대적 제한이 없고 동일한 지역에 대한 지속적인 분할살수가 가능하므로 일정 구역의 살수면적이 확보될 경우 살수차 대비 상대적으로 효과성 있는 폭염저감효과를 도출할 수 있을것으로 기대된다.

Background and Objectives The effectiveness of adjunct balloon dilation after drug-eluting stent (DES) deployment has not been sufficiently evaluated. We evaluated whether adjunct balloon dilation was associated with a reduction in major adverse cardiac events (MACEs) after long everolimus-eluting stents (EESs) implantation. Subjects and Methods Drawing from 2 randomized trials, a total of 1,672 patients treated with long EES were analyzed. Of 1,672 patients, 1,061 patients (64%) received post-stent adjunct balloon dilation. MACE, defined as a composite of cardiac death, myocardial infarction, and target-lesion revascularization (TLR), was compared between patients who received post-stent adjunct balloon dilation and patients who did not in 595 propensity score-matched pairs. Results For the matched population, MACE occurred in 29 patients (4.9%) who received adjunct balloon dilation and in 29 patients (4.9%) who did not (hazard ratio [HR], 1.01; 95% confidence interval [CI], 0.60–1.69; p=0.972). However, significant interactions were observed among the subgroups for clinical presentation and vessel size. Adjunct balloon dilation was more favored within the subset of patients with stable angina vs. the subset of patients with acute coronary syndrome (p for interaction=0.037), and within the subset of lesions with small vessel diameter (reference vessel diameter [RVD] <3 mm) vs. the subset of lesions with larger vessel diameter (RVD ≥3 mm; p for interaction=0.027). Conclusion Adjunct balloon dilation was not associated with MACE reduction at 1 year among patients requiring long EES implantation. However, post-stent adjunct balloon dilation may be necessary for patients requiring long EES implantation who present with stable angina or for lesions with small vessel diameters.

The compression index, representing the compressibility of clay, is generally obtained from the consolidation test,or predicted by empirical correlations using soil properties. However, empirical methods have regional limitations, because the compression index is affected not only by soil properties but also by site characteristics, such as deposition conditions and stress history. In this study, a method evaluating the compression index from typical soil properties is suggested using the characteristics of reconstituted clay. By analyzing the consolidation test results of Busan clay, the suggested method is verified, and the analysis of prediction error is carried out. It is shown that the proposed method evaluates the compression index more accurately than empirical methods previously suggested. The prediction errors occur by assumption, and are inversely proportional to ecross/e0, obviously.

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.
