          This study analyzes the location factors affecting the prices of apartments within 500m of the transit station area in Seoul, with focus on the transportation transfer factors. The results of the study are as follows. First, in terms of price competitiveness, the prices of the residence-only apartments are 16.5% higher than those of the mixed residential-commercial apartments. Second, the number of subway gates, the number of transfer lines, and the transfer centers have positive effects on the apartment price, but the number of transfer bus stops and the presence of a parking lot in the transit areas have negative effects on it. Third, among the apartment structural factors, the number of elapsed years has a negative effect on the apartment price, the square of the elapsed years and the presence of parking spaces have positive effects, and the heating method has a positive effect (district heating, central heating, and individual heating, in the descending order). Fourth, for the accessibility factors, the closer to the subway station an apartment is, the higher its price, but the apartment road name indicating the road accessibility does not show a significant effect on the apartment price. Fifth, among the location characteristics, the accessibility to schools, parks, and Han River shows a positive effect. Sixth, as a result of the examination of apartment complexes by dividing them into the five living zones in Seoul, the influence sizes are found to be as follows (in descending order): the southeast area (including the three districts in Gangnam), downtown, northwest, southwest, and northeast. It is thus suggested that a policy be formulated and implemented to expand the benefits of urban railways and to solve the living zone imbalance between Gangnam and Gangbuk. 본 연구는 서울시내 환승역세권 500m 이내 아파트를 대상으로 가격에 영향을 미치는 입지요인에 대한 분석으로 교통 환승요인에 중점을 두었다. 연구결과는 첫째, 일반 아파트는 주상복합 아파트보다 가격의 경쟁력에 있어서 16.5%의 우의를 보이고 있었다. 둘째, 환승 요인 중 전철역 출입구수, 환승전철 노선 수, 환승센터는 아파트 가격에 긍정적으로 나타났으나, 환승버스 정차 횟수나 환승주차장은 부정적으로 영향을 미치는 것으로 나타났다. 셋째, 아파트 구조적 요인인 중 경과연수는 음(-)의 영향을, 경과연수의 제곱과 주차공간은 양(+)의 영향을 그리고 난방 방식에 있어서는 지역난방, 중앙난방, 개별난방 순으로 영향을 미치고 있었다. 넷째, 접근성 요인에 있어서는 전철역과 거리가 가까울수록 아파트 가격에 긍정적이나 도로 접근성을 나타내는 아파트 단지 도로명은 유의하지 않았다. 다섯째, 입지특성 중학교, 공원, 그리고 한강의 접근성은 아파트 가격에 긍정적으로 작용하고 있었다. 여섯째, 아파트 단지를 행정구역상 서울시 5대 생활권으로 구분하여 살펴본 결과, 영향력 크기순은 강남3구가 있는 동남권, 도심권, 서북권, 서남권, 동북권 순으로 나타났다. 이와 같은 연구는 도시철도 수혜확대와 강남과 강북 간 생활권 불균형 해소를 위한 정책이 필요하다는 시사점을 주고 있다.

        • 情意的特性과 그 先行變因이 學業成績에 미치는 影響

          金龍來 弘益大學校 敎育硏究所 1993 敎育硏究論叢 Vol.- No.9

          1. Purposes The purposes of this study were to clarify on the influences of contribution variables - Korean secondary (middle and high) school learners' affective characteristics variables (self-concept, school learning motivation, and locus of control) and its antecedent variables(school-related adjustment, parents' expectations to school learning achievement for their children, and situation- related anxiety) toward their academic achievement. 2. Hypotheses The following hypotheses were made on the basic of the preceding theoretical background. (Hypothesis 1) : Antecedent variables to learners' affective characteristic variables will be predict significantly toward learners' academic achievement respectively. (Hypothesis 2) : Learners' self-concept and its sub-factors influence significantly toward academic achievement respectively. (Hypothesis 3) : Learners' school learning motivation, locus of control, and these subfactor(or areas) influence significantly toward academic achievement respectively. (Hypothesis 4) : Learners' self-concept, school learning motivation, and locus of control are significant differences relative contributions (effects) toward academic achievement by sex, level of schools respectively. (Hypothesis 5) : The direct/indirect influences of antecedent variables and affective characteristics variables are significant differences in the relative contributions of toward learners' academic achievement. 3. Methods The subjects in this study - 2,700 male and female Korean secondary school learners from Seoul and other areas were sampled, of whom 2,226 were finally analyzed. For this study, instruments for measurement of each variable were developed the five scale - the instruments with factorial validity and reliability were 「School-Related Adjustment Scale」, 「Situation-Related Anxiety Scale」, 「Self-Concept Scale」, 「School Learning Motivation Scale」, and 「Locus of Control Scale」. The collected data were analyzed Pearson's corrlations, multiple regression, and path analysis through SPSS/PC+ and SPSS^x program, and all statistical values were tested by t-test and F-test in significant level of p < .05. 4. Results The results were analyzed according to the hypotheses, and the findings of this study were as follows 1) The antecedent variables toward Korean secondary school learners affective characteristics variables were positive influences effects on learners' academic achievement respectively. And there were confirmed statistically significant correlations between the antecedent variables and learners' academic achievement. 2) The combined influences of the academic self-concept(ASC) and nonacademic self-concept(NASC) on academic achievement were 30.30%, and the relative effects of ASC and NASC were 24.23% and 6.07% respectively. And there were confirmed statistically significant correlations between Korean secondary school learners' self-concept and the academic achievement. Therefore, self-concept was verified as the affective characteristics variables with the most meaningful influence toward Korean secondary school learners' academic achievement. 3) The combined effect of the school lerning motivation (21.10%) and 'internality' of locus of control (0.00%) on the academic achievement were 21.10%, the combined effect of the school learning motivation (21.10%) and `powerful others'(0.60%) on the academic achievement were 21.70%, and that effects of the school on the learning motivation (21.10%) and `chance' (0.50 %) on the academic achievement were 21.60%. Accordingly, Korean secondary school learners `school learning motivation was affected mainly for learners' academic achievement, while locus of control was found a little influence toward academic achievement. 4) The relative effect of Korean secondary school learners' self-concept, school learning motivation, and locus of control on the academic achievement were 21.20 % (school learning motivation), 1.5% (self-concept), 0.6%(powerful others), 0.5% (internality), and 0.2%(chance) respectively. Therefore, these variables were effected significantly toward academic achievement, but the most effective influence variable was `school learning motivation'. And there were significant correlations between locus of control and academic achievement, but there was examined the positive significant correlation in the case of 'internality'. 5) The range of total effect of the six variables (antecedent variable : school-related adjustment, parents' expectations to school learning achievement for their children, situation-related anxiety; affective characterstics variables : self-concept, school learning motivation, and locus of control) in the causal model of this study was '.460 ∼-.171'. Therefore, the direct/indirect effect of Korean secondary school learners' contribution variables toward learners' academic achievement were found definitely a difference, but sub-areas of the locus of control were found a little effects toward academic achievement.

          고위공직자 청렴도와 기관 청렴도 간 그랜저 인과관계 실증분석 - 한국철도공사를 중심으로 -

          김용래 감사연구원 2019 감사논집 Vol.0 No.32

          This study was analyzed through the Granger causality test based on the time series data of the Korea Railroad Corporation to analyze the causal relationship between the integrity of high-ranking public officials and the integrity of the institution. First, it was found that the integrity of high-ranking public officials and the internal integrity were mutually affected. In other words, the improvement of internal integrity has improved the integrity of high-ranking public officials, and the improvement of integrity of high-ranking public officials has improved internal integrity. Second, the integrity of high-ranking public officials was found to affect external integrity, but it did not affect the opposite. This seems to have led to the improvement of external integrity by performing fair and transparent work because the integrity of high-ranking public officials has also affected public officials in public affairs. Third, the integrity of high-ranking public officials also showed an impact on overall integrity, but it did not affect the opposite. Although the policy customer evaluation items were excluded from this study, the positive impact of internal and external integrity seems to affect institutional integrity. On the other hand, this study is meaningful in that it has been empirically analyzed about the importance of high-ranking public officials' morality in the new area of integrity of high-ranking public officials that have not been covered in previous studies. In addition, in order to improve the integrity of the institution, it is suggested that a cultural system is needed to improve internal integrity along with a policy to enhance the integrity of high-ranking public officials. 본 연구는 고위공직자 청렴도와 기관 청렴도 간 인과관계를 분석하고자 한국철도공사의 시계열 자료를 바탕으로 그랜저 인과관계 검정을 통하여 분석하였다. 연구결과 첫째, 고위공직자의청렴도와 내부 청렴도간에는 상호 영향을 미치는 것으로 나타났다. 즉 내부청렴도의 향상은 고위공직자 청렴성의 향상을 가져오고, 고위공직자 청렴성의 향상은 내부청렴도 향상을 가져오는것으로 나타났다. 둘째, 고위공직자 청렴도는 외부청렴도에 영향을 미치는 것으로 나타났으나, 반대의 경우에는 영향을 미치지 않은 것으로 나타났다. 이는 고위공직자 청렴성은 대민업무에서 이루어지고 있는 공직자에게도 영향을 미쳐 공정하고 투명한 업무수행으로 외부청렴도 향상을 가져온 것으로 보여 진다. 셋째, 고위공직자 청렴도 역시 종합청렴도에 영향을 미치는 것으로 나타났으나, 반대의 경우에는 영향을 미치지 않은 것으로 나타났다. 비록 정책고객평가 항목이 본 연구에서 제외되었지만 내․외부청렴도의 긍정적인 영향은 기관 종합청렴도에도 영향을 미치는 것으로 판단된다. 한편 본 연구는 그간 선행연구에서 다루지 않았던 고위직공직자 청렴도라는 새로운 영역에대하여 고위공직자 도덕성의 중요성에 대하여 실증 분석한 것은 나름대로 의의가 있다고 할 것이다. 아울러 기관 청렴도 향상을 위해서는 고위공직자의 청렴성을 제고하는 정책과 함께 내부청렴도를 향상 시킬 수 있는 문화적 제도가 필요하다는 시사점을 주고 있다.

          태양광 인버터의 노치 필터 최적 설계

          김용래,허철영,이영권,최익,최주엽 한국태양에너지학회 2019 한국태양에너지학회 논문집 Vol.39 No.2

          When Photovoltaic inverter is connected to grid and used as PVPCS (Photovoltaic Power Conditioning System), 120 Hz AC ripple occurs at the dc-link capacitor voltage. This AC ripple reduces the efficiency of PVPCS and shortens the lifetime of the capacitor. In this paper, we design a notch filter to remove AC ripple. As a result, the AC voltage ripple was removed from the dc link and the THD of the PVPCS output current with the notch filter was lowered. This notch filter is determined by the damping coefficient, the bandwidth coefficient, and the switching frequency. Among these, the switching frequency determines the switching loss and the size of the LC filter, and the PVPCS with the high switching frequency has a greater efficiency loss due to the switching loss than the efficiency improvement by the notch filter. Therefore, it is important to set the optimum switching frequency in the PVPCS with the notch filter applied. In this paper, THD and switching loss of PVPCS output current with notch filter are calculated through simulation, and cost function to calculate optimum switching frequency through data is proposed.

          This study was conducted to determine the location determinants that influence the sales of the "Storyway" convenience stores built at the country’s railway stations. The preceding studies were about the convenience stores located in the residence-business areas or along the roadsides. This study, on the other hand, focused on the characteristics of the stations, based on a theory that is different from the existing theories. The targets of this study were the 301 "Storyway" convenience stores doing business in the 198 railway stations in the country, and the dummy parameter and hedonic-price model function were used for multiple regression analysis. For the study results, it was found that the number of people using the railway and the size of the store have a positive effect on the sales whereas the other brand competitors have a negative effect thereon. Second, the subway stations holding 89% of the total passengers in the country have unexpectedly no positive influence on the sales. Third, depending on the transfer, it was found that no transfer station had smaller sales than the transfer stations. Finally, as for the location of the stores in the station, the stores located on the platforms or passageways have a smaller turnover rate than the stores in the welcoming spaces and squares. This research result shows that when starting a convenience store business, the number of people using the railway, the size of the store, the transfer possibility, and the location of the store inside the station have to be considered under the circumstance of recession on the part of the convenience stores due to excessive competition. 본 연구의 목적은 철도역사내에서 영업 중인 스토리웨이 편의점 매출에 영향을 미치는 입지요인에 대하여 분석하고자 함이다. 기존 선행연구는 주거・상업지역 또는 도로변에 위치한 편의점 위주로 이루어졌다. 본 연구는 철도교통로 인한 철도역사의 특성을 반영하여 기존 선행연구와의 차별성을 두었다. 연구의 대상 편의점은 전국 198개 역사 내에서 운영 중인 스토리웨이 301개이며 전국과 수도권으로 구분하여 더미변수와 헤도닉 가격 모형 함수를 활용한 다중회귀분석을 시행하였다. 연구결과 첫째, 철도이용인원과 점포 면적은 매출액에 정(+)의 영향을 미치고 있었으나, 다른 브랜드 경쟁 편의점은 부(-)의 영향을 미치고 있었다. 둘째, ktx정차역 등 국철역이나 전철역 등 철도역사 형태는 매출액에 별다른 영향을 주지 못하며, 환승여부에 따라 미 환승역이 다른 환승역보다 매출액이 더 감소하는 것으로 나타났다. 셋째, 점포 위치에 있어서도 승강장과 연결통로에 위치한 점포는 맞이방이나 광장에 위치한 점포보다 매출액이 감소하는 것으로 나타났다. 이와 같은 연구 결과는 현재 국내의 편의점은 과다 경쟁으로 인하여 쇠퇴기에 들어간 시점에서 향후 철도역사내 편의점 창업시에는 철도이용인원과 면적, 경쟁점, 환승여부, 그리고 맞이방이나 광장 등 고객이 가시성이 좋은 곳에서 창업을 해야 한다는 시사점을 지닌다.
