본 연구는 전통적인 다짐관리방법의 문제점을 보완하고자 TDR(Time Domain Reflectometry)을 이용하여 지반의 함수비와 건조단위중량을 측정하는 연구를 수행하였다. 개발된 Flat TDR 시스템의 측정값을 검증하기 위해 여섯 가지 시료를 대상으로 실내실험을 수행하였다. 또한 실내실험을 바탕으로 현장시험을 수행하여 현장 적용성을 검토하였고, 신뢰성을 확보하기 위해 Purdue TDR 시스템과 비교실험을 수행하여 정밀도를 확인하였다. 또한 유한요소해석을 수행하여 Flat 프로브의 영향범위를 확인하였다. 그 결과 약 10cm의 영향범위를 확인하였고, 실내실험결과 함수비는 평균적으로 약 0.4%의 오차를 보이며, 건조단위중량의 경우 약 1.6%의 오차를 보였다. 현장시험의 경우 함수비는 0.8%, 건조단위중량의 경우 2.5%의 오차를 보였다. 실험 결과를 통하여 Flat TDR 시스템의 측정값은 기존의 TDR 시스템보다 정확한 값을 도출하는 것을 확인할 수 있었다. This study has been conducted to improve the conventional compaction management method by measuring the water content and dry unit weight of soil using the Time Domain Reflectometry (TDR) method. In order to verify the measured value of the developed flat TDR system, laboratory tests were conducted on six soils. Also, based on laboratory experiments, field tests were conducted to evaluate the applicability of the developed flat TDR system. Also, a comparison experiment was conducted with the Purdue TDR system. In addition, FE analysis was done to confirm the influence range of the Flat probe. As a result, it was confirmed that the influence range was about 10 cm. As a result of laboratory experiment, the water content ratio showed an error of about 0.4% on the average, and in the case of dry unit weight, it showed an error of about 1.6%. For the field test, the water content ratio and unit weight showed an error of 0.8% and 2.5%, respectively. Through the experimental results, it was confirmed that the measured value of the Flat TDR system is more accurate than that of the conventional TDR system.

중소제조업체의 PB 생산 관여의 동기적 요인이 기업성과에 미치는 영향

김완민 ( Kim Wonmin ),이한근 ( Lee Hangeun ),강성호 ( Kang Seongho ) 한국유통경영학회(구 한국유통정보학회) 2018 유통경영학회지 Vol.21 No.2

최근 중소제조업체들은 지속적인 성장 동력 및 경쟁력을 확보하기 위해 유통업체 브랜드 생산(private brand: 이하 PB)을 중요한 성장 요인으로 인식하고 있다. 이는 PB 시장점유율이 크게 성장함에 따라, 중소제조업체의 브랜드 자산, 유통업체의 관계 강화, 매출 증대 등 다양한 가치를 창출할 수 있는 원동력으로 작용하기 때문이다. 하지만, 중소제조업체 관리자들은 PB를 생산하는 것이 기업의 성장전략에 중요한 관리적 요소임을 인지하고 있으나, 자사가 기대하는 기업 성과에 어떠한 영향을 미치는지에 관해서는 의문점으로 제시하고 있다. 이에 본 연구에서는 자원기반이론을 토대로 중소제조업체가 PB 생산에 관여하는 동기를 ‘이익추구 동기’와’손실회피 동기’로 구분하고 중소제조업체의 성과에 미치는 영향을 실증 조사하였다. 실증 분석결과, 중소공급업체의 이익추구 동기인 R&D 역량은 PB 생산 관여에 긍정적 영향을 미치나 마케팅 역량은 PB 생산 관여에 영향을 미치는 것으로 확인되었다. 또한, 중소공급업체의 PB 생산은 기업의 재무적 성과와 시장성과를 증대시키는 것으로 파악되었다. 이러한 분석결과를 바탕으로 본 연구에서는 학문적 · 실무적 시사점을 제시하였다. This study examines how manufacturing SME`s Private Brand(hereafter called PB) production motivation, specifically rent-seeking motivation and loss-avoidance motivation influences their performance. The explicit purpose of this study was to reveal the mechanism through which manufacturing SME`s PB production motivation affects the firm`s performance. Drawing on the resource based theory, we hypothesized the relationship between firm`s PB production motivation(rent-seeking motivation: brand capability, R&D capability, loss-avoidance motivation: brand reputation, and channel bonding capabilities) and performance(financial performance and market performance) through the engagement of PB production. To test the hypotheses, reponse were obtained from 201 manufacturing SME`s in South Korea. The proposed model was estimated using structural equation modeling. The results indicated that R&D capabilities, brand reputation, and channel bonding capabilities were positively related to the engagement of PB production, but marketing capabilities was not. Also, the engagement of manufacturing SME`s PB production positively associated firms` financial and market performance. The theoretical and practical implications of the present research are discussed, together with its limitations.

김완민(Kim Wan-Min),배미현(Bae Mi-Hyun) 동북아시아문화학회 2011 동북아 문화연구 Vol.1 No.26

The purpose of this study is to investigate how brand name, perceived price, and perceived quality have an effect on intention of loyalty (switching intentions and WOM-intentions) to PB (private brand) via satisfaction with PB. The data for analysis was obtained from 319 customers who have experience to use PB in large discount stores. The results showed the following. First, brand name had a significant positive influence on overall satisfaction with PB. Second, perceived price had a significant positive influence overall satisfaction with PB. Third, perceived quality had a significant positive influence on overall satisfaction with PB. Finally, satisfaction with PB was found to have significant positive impacts on loyalty (switching intentions and WOM-intentions). According to the results of this research, large discount stores have to focus on PB. It is necessary to understand the role of PB as a customer's store loyalty-related item. Managerial implications and the limitations of this research are also discussed.

서비스 제공자의 감정노동에 관한 고객공감이 고객 반응에 미치는 영향에 관한 연구

김완민(Kim, Wan-Min),강성호(Kang, Seongho),이한근(Lee, Hangeun) 한국서비스경영학회 2016 서비스경영학회지 Vol.17 No.1

The purposes of the present study were (1) to investigate emotional display type (surface acting vs deep acting), (2) to conceptualize customer empathy (cognitive empathy vs affective empathy), and (3) to empirically test an our assumption that emotional regulatory strategies enhance the customer empathy, which eventually improves customer satisfaction and trust. Data from 160 customers in general hospitals is used to test the hypotheses. Results from a structural equation model show that surface acting has a positive influence on cognitive empathy, whereas deep acting is positively related to affective empathy. Also, cognitive empathy has a positive effect on customer satisfaction, but it was not significantly related to trust. In addition, affective empathy is positively related to customer satisfaction and trust. The conclusion provides theoretically and managerial insights, discuss the limitations of the present study, and makes directions for future study.

한국, 중국, 일본에서 경기자의 성별에 따른 상금 차이

김완민(Wan-Min Kim),최태영(Tae-Yeong Choi) 동북아시아문화학회 2016 동북아시아문화학회 국제학술대회 발표자료집 Vol.2016 No.7

U.S. women’s soccer team, the champion of Women’s World Cup in Canada 2015, made $2 million, which is a tiny fraction of the $35 million the German men’s team made for winning the Men’s World Cup in Brazil 2014. Soccer is not the only professional sport where there is a wide gender gap in prize money. At the U.S. Women"s Open in 2015, prize money for the champion female golfer is $810,000 while $1.8 million was given to the male champion at the men’s U.S. Open in the same year. However, some professional sports have reached parity. At the 2015 Wimbledon, both the winner of the men’s final and the women’s final will earn about $2.9 million as a prize. Since 2007 when Wimbledon finally joined prize parity, four tennis Grand Slam tournaments have provided equal prize money to men and women players. This paper will analyze opinions and theoretical background on prize parity across players’ gender. We will also investigate the existence and magnitude of prize gap across genders in professional sports in Eastern Asia. Then the determinants of prize gender gap in professional sports held at that region will be examined. In particular, the effect of cultural difference in women’s role in Korea, China, and Japan on gender gap in prize structure will be the core contribution of this paper.

This paper introduces a new approach method on science and technology level assessment by using growth curve model concept. It may make readers possible to understand in dynamic analysis approach since growth model is rooted on the historical and empirical development of measuring biological growth pattern of plants, animals and viruses, etc. The paper used Gompertz and Weibull models and compared both models or which model might be better fitting. The Gompertz growth curve model has been the only and popular one used to analyze general technology level assessment in Korea for the last ten years since Bark(2007). There has been some arguments about possibility of other substitute model for the matter including Weibull model. Kim and Bark(2015) introduced the Weibull growth curve model to measure the technology level assessment of some fishery areas. This study tries widening its usage for more general scope of technology areas by introducing the result of fishery and construction engineering areas, which are relatively compared in terms of technology characteristics of its own. The study draws possible conclusion to see whether both Gompertz and Weibull models better represent growth pattern of biological oriented ones or which one better fits. Adding to that, the paper tries to see whether science and technology growth patterns of these two concerned areas are similar or identical with time lag between Korea and countries with the state-of-the art including Japan.
