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.

생약제제(Miracle20(R))가 육계의 생산성과 영양소 이용률 , 소장내 미생물 균총 및 면역기능에 미치는 영향

홍성진,남궁환,백인기 한국동물자원과학회 2001 한국축산학회지 Vol.43 No.5

An experiment was conducted to investigate the effects of supplementary herbal products [Miracle20^ⓡ(M20)] on the performance, nutrient digestibility, small intestinal microflora and serum IgG level in broiler chickens. One thousand one-day-old broiler chickens(Ross^ⓡ) were assigned to five treatments: control(T1), 50ppm chlorotetracycline(CTC; T2), 0.2% M20-S(T3), 0.2% M20-D(M20-S fortified in Angelica gigas, Dioscorea japonica and Schizandra chinensis; T4), 0.2% M20-A(M20-S minus Schizandra chinensis and plus Plellidendron amurense; T5). Each treatment had four replications (two for each sex) of 50 birds. Growth performance was not significantly affected by dietary treatments. The herbal products supplementation tended to improve the weight gain of male broiler chicks, but showed no significant difference. Nutrient digestibilities and ammonia gas level on the litter were not significantly affected by treatments. The colony forming unit(CFU) of CI. perfringens in small intestine was significantly lower in treatments T2 and T5 at 26 days of age while the CFU of E. coli was significantly lower in T3 compared to T1 at 42 days of age(P$lt;0.05). The level of serum IgG tended to increase with dietary herbal products supplementation. These results indicate that dietary herbal products(M20) do not significantly affect growth performance and nutrient digestibilities in broiler chickens but have positive effects on small intestinal microflora and serum IgG level.

홍성진,임희석,백인기 한국동물자원과학회 2002 한국축산학회지 Vol.44 No.4

Methionine chelate 형태로 Cu 및 Zn의 첨가가 육계의 생산성과 영양소 이용률, 혈청 IgG 수준, 근위의 손상정도(gizzard erosion index) 그리고 간과 배설물의 Cu와 Zn 함량에 미치는 영향을 알아보기 위해 갓 부화한 1,000수의 Ross^R병아리를 4처리 5반복, 반복당 50수(암·수 각각 25수씩)를 배치하여 5주간 사양시험을 실시하였다. 시험사료는 대조구 사료에 Cu와 Zn를 methionine chelate 형태로 100 ppm씩 단독 또는 혼합첨가하여 만들었다. 증체량은 chelate 첨가구들 모두 대조구 보다 높았고(P<0.05), 사료요구량은 chelate 첨가구들이 대조구 보다 낮았다(P<0.05). Cu와 Zn를 혼합하여 첨가한 처리구의 증체량과 사료효율은 Cu 및 Zn chelate 첨가에 의해 유의한 영향을 받지 않았다. 혈청 IgG 농도는 Cu와 Zn chelate 혼합처리구가 대조구에 비해 유의하게 높았으나(P<0.05), 근위 궤양 정도는 처리에 따른 차이가 없었다. 간과 배설물 내 Cu 및 Zn 함량은 사료에서 이들 광물질의 함량에 의해 영향을 받았다(P<0.05). 결론적으로 Cu와 Zn chelate 단독 또는 혼합하여 첨가시 육계의 증체량과 사료효율을 개선시키고 혈청 IgG 농도를 증가시키며 간 내 Cu와 Zn 수준은 유의한 영향을 받지 않으나 분내 Cu와 Zn의 함량은 증가시키는 것으로 나타났다 An experiment was conducted to investigate the effects of supplemental copper or/and zinc methionine chelates(Cu-Met or/and Zn-Met) on the performance, nutrient digestibility, serum IgG level, gizzard erosion, and the contents of Cu and Zn in liver and excreta of broiler chickens. One thousand d-old broiler chickens (Ross^R) were assigned to 4 treatment; control, 100 ppm Cu in methionine chelate(Cu-Met), 100 ppm Zn in methionine chelate(Zn-Met) and 100 ppm Cu plus 100 ppm Zn in methionine chelate(Cu-Zn-Met). Each treatment had five replications of 50 (25 male + 25 female) birds each. Average weight gains of chicks fed chelated Cu or/and Zn were significantly higher than that of chicks fed the control (P<0.05). Moreover, feed conversion rates of chicks were better in the chicks fed chelated Cu or/and Zn than in the chicks fed the control (P<0.05). The birds fed the chelated Cu and Zn(Cu-Zn-Met) tended to perform the best growth rate and feed conversion rate. Nutrient digestibilities were not affected by the dietary treatments. Serum IgG level of chicks fed Cu-Zn-Met was significantly higher than that of chicks fed the control (P<0.05). Gizzard erosion index was not significantly different among the treatments. The contents of Cu and Zn in liver were not significantly affected by the dietary treatments. The excreta contents of Cu or/and Zn were significantly high in the birds fed supplementary Cu or/and Zn. It was concluded that dietary supplementation of Cu or/and Zn in methionine chelated form improved growth and feed conversion efficiency of broilers.

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 purpose of this study is to collect and analyze information related to water leaks that cannot be easily accessed, and utilized by using the news search results that people can easily access. We applied a web crawling technique for extracting big data news on water leakage accidents in the water supply system and presented an algorithm in a procedural way to obtain accurate leak accident news. In addition, a data analysis technique suitable for water leakage accident information analysis was developed so that additional information such as the date and time of occurrence, cause of occurrence, location of occurrence, damaged facilities, damage effect. The primary goal of value extraction through big data-based leak analysis proposed in this study is to extract a meaningful value through comparison with the existing waterworks statistical results. In addition, the proposed method can be used to effectively respond to consumers or determine the service level of water supply networks. In other words, the presentation of such analysis results suggests the need to inform the public of information such as accidents a little more, and can be used in conjunction to prepare a radio wave and response system that can quickly respond in case of an accident. 본 연구의 목적은 사람들이 쉽게 접할 수 있는 포털의 뉴스 검색 결과를 활용하여 쉽게 접근, 활용하지 못하는 상수도 누수 관련 정보를 모아 분석하는 것이다. 상수도 시스템의 누수사고 빅데이터 뉴스의 추출을 위한 웹크롤링 기법을 적용하고 정확한 누수사고 뉴스를 획득하고자 알고리즘을 절차화하여 제시하였다. 또한 추출된 누수사고 기사에서 발생일시, 피해영향, 발생지점, 피해원인, 피해시설 등과 같은 추가적인 정보의 획득이 가능하도록 상수도 누수사고 정보 분석에 적합한 데이터 분석 기법을 개발하였으며 그에 따른 적용결과를 제시하였다. 본 연구에서 제안한 빅데이터 기반 누수 분석을 통한 가치 추출은 기존의 상수도통계 결과와 비교를 통한 유의미한 가치를 추출하는 데 1차적 목표가 있으며, 이와 같은 분석 결과를 활용하여 향후 누수 사고 대응에 있어 소비자의 반응에 효과적으로 대응하거나 서비스 수준을 결정하는데 활용할 수 있다. 즉, 이와 같은 분석결과의 제시를 통해 사고와 같은 정보를 대중에 조금더 알려야하는 필요성을 제시하고, 사고 발생시 빠른 대처가 가능할 수 있는 전파 및 대응 체계를 마련하는데 연계활용할 수 있다.

Patent ductus arteriosus (PDA) continues to be one of the most common problems found in premature infants. The incidence is inversely related to gestation, but may be reduced by use of antenatal steroids, lower volume fluid regimen and judicious use of phototherapy. However, there continues to be controversy as to the appropriate indications for treatment, varying from prophylaxis on the basis of gestation to treatment only when a PDA is demonstrably significant. The situation is further complicated by differing diagnostic criteria for ductal patency or significance. Early treatment of significant or symptomatic PDA depends upon accurate diagnosis. PDA closure can then be achieved using medical means, with surgery reserved for patients in whom this fails or in whom there are contra-indications. However, the optimum timing for intervention remains unknown.
