K리그 축구 경기에서 나타난 상황 요인 별 주요 공격 분석인자의 상대성 분석
김종원 ( Kim¸ Jongwon ),최형준 ( Choi¸ Hyongjun ) 한국체육학회 2021 한국체육학회지 Vol.60 No.1
본 연구는 2020 K리그 경기에서 발생한 주요 공격 인자들을 수집하고 이를 상황 요인(경기 장소, 상대팀 수준, 최근 팀 경기력, 최근 상대팀 경기력) 별 상대성 분석을 하고자 하였다. 본 연구에서는 2020 K리그 모든 팀들의 전 경기(스플릿 후 경기 제외)를 대상으로 하였으며, 연구의 대상이 된 경기 수는 132경기였다. 자료 수집을 위해 한국프로축구연맹에서 제공하는 ‘데이터포탈’의 공식 자료를 사용하였고, 자료를 정리하기 위해 1차적으로 Microsoft Office Excel 2007을 이용하였다. 통계 분석은 IBM SPSS 25.0을 이용하였으며, 정규성 분포를 이루지 않아 비모수 통계 기법인 Mann-Whitney U 검정법과 Kruskal-Wallis H 검정법을 이용하여 평균 차이를 비교 분석하였다. 본 연구에서 나타난 결과는 첫째, K리그 팀들은 홈에서 경기를 할 때가 원정에서 경기를 할 때보다 더 높은 볼 점유율을 기록했고(α<.05), 둘째, 강팀을 상대로 경기할 때가 중팀과 약팀을 상대로 할 때보다 더 적은 슛, 유효 슛, 패스, 전진 패스와 낮은 볼 점유율을 기록했으며(α<.05), 셋째, 팀의 최근 경기력이 좋을 때와 상대팀의 경기력이 좋지 않을 때 더 많은 패스, 전진 패스와 높은 볼 점유율을 기록했다(α<.05). The aim of this study was to identify the effect of situational variables e.g. match venue, opposition quality, current form, current opposition’s form on key attacking performance indicators from 2020 Korea Football League. All match(n=132) excepted for split matches were used for analysis and the data were provided by Korea Professional Football League(data.kleague.com). Microsoft Office Excel 2007 was used to collect data and the data were analysed in IBM SPSS 25.0 to determine differences between independent variables. Normality tests were firstly conducted and Mann-Whitney U test and Kruskal-Wallis H test was conducted as a non-parametric statistics method. The results showed that ball possessions were significantly different between home and away teams whilst all key attacking performance indicators were significantly different according to different quality of team. Also, there were significant differences in passes, forward passes and ball possessions among current team forms and opposition team forms.

In recent times, earthquakes of various magnitudes have been occurring frequently within the country, occasionally resulting in significant damage to both human lives and the power infrastructure. Particularly, Gas Insulated Switchgear (GIS), one of the essential components ensuring a stable power supply in the domestic electrical grid, demands a high level of earthquake safety. GIS consists of intricate devices and structural components, and its scale is quite substantial. Moreover, electrical facilities are subjected to diverse design loads during operation, necessitating the assurance of structural integrity against these overall loads. Safety assessments for seismic performance are accurate and intuitive when conducting direct tests that meet these conditions. However, in the case of Gas Insulated Switchgear, direct testing is not feasible due to cost and test facility constraints. Therefore, this paper evaluates the structural safety of GIS based on relevant standards using dynamic analysis methods, including response spectrum analysis and static analysis. The assessment of a 170kV GIS indicates that key components in critical locations meet the seismic performance requirements, and the component experiencing the maximum stress also has a safety margin of more than 10%.
민사신탁 관련 지방세 과세에 관한 연구 - 담보권신탁의 등록면허세를 중심으로 -
김종원 ( Jongwon Kim ) 한국지방세학회 2016 지방세논집 Vol.3 No.2
신탁법 제2조의 신탁설정 유형에 관련된 지방세법 비과세 규정의 부정합성으로 인해 법 해석에 있어 어려움이 있다. 신탁재산의 이전에 대해 비과세 적용이 가능한지 여부에 대해 관련자들 간에 견해 차이가 생겼다. 이에 비과세 규정의 문제점을 검토하고 입법적 개정안을 제시하였다. 지방세법 상 신탁 관련 등록면허세 비과세 규정이 삭제된 이상 신탁을 원인으로 한신탁재산 이전 등기 등을 비과세 대상으로 볼 아무런 법적 근거가 없다는 과세관청의 견해인 과세 긍정설은 등기에 관한 세율을 적용할 수 있다는 것이다. 등록면허세 과세 여부에 대한 혼란을 종식시키려면 지방세법 비과세 조문의 개정이 필요하다. 신탁재산 등기에 대한 취득세 비과세 규정인 지방세법 제9조 제3항에 등록 면허세도 비과세 하는 것으로 명시하는 방안이나 등록면허세 비과세 근거 규정인 지방 세법 제26조에 신탁관련 규정을 추가하면 신탁설정 유형 전반에 대해 일관성 있는 비과세 적용을 할 수 있게 된다. There is a difficulty in the interpretation of the law because Local Tax Act exemption regulations on the type of trust setting in Article 2 of the Trust Act are ambiguous. People are disagreeing about tax exemption for the transfer of trust assets. I review the evidence and propose legislative amendments. The taxation hypothesis is the opinion of the local tax authorities that the tax rate of Local Tax Act can be applied to lien rights trusts because the tax exemption regulation of the Local Tax Act has been deleted and there is no legal basis for registration of trust property transfers. In order to end the confusion over registration license tax, it is necessary to revise the tax exemption clause of Local Tax Act. If you add trust related regulations to the Article 26 of the Local Tax Law, which is a tax exemption provision for the registration tax, or a method to specify that the registration tax is also tax-exempted under Article 9 (3) of the Local Tax Law, which is a tax exemption for trust property registration, It is possible to apply consistent tax exemption.

When measuring temperature with a voltage divider, and changing the variation of the thermistor resistance from the temperature to the voltage, the divider resistance greatly impacts the resolution of each analog-to-digital converter (ADC) step. This work presents a method for determining the divider resistance to minimize the resolution’s average in a given temperature set. The proposed method was applied to the four types of commonly used negative temperature coefficient (NTC) thermistors. We also investigated the influence on the average resolution of the incorrect selection of the resistance. The simulation results showed that the average resolution can be worse more than 2.6 times, if the thermistor's resistance at the utmost temperature of the given set was chosen as the divider resistance.

Aircraft fuel systems are one of the core electronic and mechanical systems of aircraft and the reliability of the fuel system for safe flight is of paramount importance. Despite the use of advanced technology and equipment, however, modern aircraft fuel systems still have vulnerabilities due to simple faults or crew carelessness. In this paper, we proposed an integrity monitoring method that uses an aircraft fuel consumption prediction algorithm to prevent accidents caused by aircraft fuel system errors that require high reliability and accuracy. The proposed aircraft fuel consumption prediction algorithm trained by the Levenberg-Marquardt learning method could confirm 20~30% higher robustness and superiority against the external environmental noise compared with the conventional aircraft fuel consumption model in the simulation using the B747-100 aircraft data.
