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.

The Korea government has strongly encouraged the universities and research institutes to launch new business in order to strengthen the nation's weakened competitiveness after the IMF foreign exchange crisis, foster the new industry, and stabilize the job market. However, the domestic business incubator has attached importance to quantitative growth with paying no attention to the qualitative one, due to the competitive establishments of the government agencies. The purpose of this study is to have a new understanding of the overall situation on the new business, and promote the qualitative growth of the domestic business incubator along with the quantitative one. In addition, this study aims at the role of the universities for the promotion of the BI, having an eye on the fact that about 98% of the government-affiliated business incubators have been established in universities, and discusses the position of the universities for the technology-intensive venture businesses and the effective plans, considering that most of the moving-in businesses are the venture businesses equipped with their own new technology. This study proposes an effective plan which is necessary for the universities to run the BI, such as the goal, the supporting services, facilities, human resource management, and the detailed self-supporting plans of the new businesses. 우리나라에서는 IMF 외환위기 이후 약화된 국가경제력 강화 및 신규 산업의 육성, 고용시장의 안정화를 위해 정부주도로 대학, 연구기관 등의 창업을 적극 장려하고 있다. 하지만 국내 창업보육사업은 그 동안 정부산하 기관들의 경쟁적인 설립으로 인해 질적인 발전은 소홀히 한 채, 양적 발전에만 치중해 왔다. 본 연구는 이러한 문제의식을 가지고 창업에 걸친 전반적인 상황을 재인식하고, 현재 국내 창업보육센터의 양적발전에 걸맞은 질적발전을 도모하고자 그 목적을 두었다. 또한, 정부기관 산하 창업보육센터(BI)중 약 98%가 대학에 설립되어 있다는 점에 착안하여 BI의 육성을 위한 대학의 역할에 주안점을 두고 접근하였으며, 입주기업의 대부분이 신기술을 가지고 시장에 진입하고자 하는 벤처기업인 것을 고려하여 기술집약적인 벤처기업을 위한 대학이 가져야할 자세와 효과적인 방안에 대하여 논의하였다. 본 연구에서는 대학이 창업보육사업을 운영하는 데 있어서의 효과적인 방안으로, 목표, 지원서비스, 시설, 인적자원, 그리고 신생기업들의 자립방안 측면과 세부 방안을 제시하였다.

김완민,강성호,이한근 한국유통과학회 2017 유통과학연구 Vol.15 No.2

Purpose – Previous studies related to emotional labor of salespeople have mainly focused on identifying the antecedents of emotional exhaustion and turnover intention and exploring the mitigating effects salespeople’s motivation on emotional exhaustion and turnover intention. They also demonstrates that there are different roles for moderating in social support, which means mental/physical support related to the job in supervisors, colleagues and organizations. The purpose of this paper is to investigate how service employees’ surface acting affect turnover intention through emotional exhaustion. Another important objective of this paper is to investigate whether perceived social support moderates 1) the relationship between surface acting and emotional exhaustion 2) the relationship between emotional exhaustion and turnover intention. Research design, data, and methodology – To test the hypotheses, we collected the data from Korean insurance company sales employees. A total of 235 responses were received, from which 220 usable responses were obtained after list-wise deletion. Working with a sample of 220 responses, structural equation modeling was employed to empirically test research hypotheses(<H1> The relationship between surface acting and emotion exhaustion, <H2> The relationship between emotion exhaustion and turnover intention, <H3> The moderating effect of perceived social support(PSS) on the relationship between surface acting and emotion exhaustion, and <H4>The moderating effect of perceived social support(PSS) on the relationship between emotion exhaustion and turnover intention. SPSS 22.0 and AMOS software were used in these data analysis. Results – The service employees’ surface acting was positively related to the emotional exhaustion; in turn, the service employees’ feelings on emotional exhaustion are positively related to turnover intention. In addition, Perceived Social Support significantly moderated the relationship between surface acting and emotional exhaustion. However, perceived social support has a non-significant moderating effect on the path from emotional exhaustion to turnover intention. On the basis of these results, the following conclusion can be drawn. First, distribution service companies will be needed the administrative efforts to offer counseling programs and space to provide their members with enough rest in experiencing psychological pain due to the salespeople's surface acting. Also, it is necessary for distribution service companies to identify and share the examples of successfully solving emotional exhaustion caused by salespeople's surface acting.

김완민,배상욱,이상홍 한국마케팅관리학회 2006 마케팅관리연구 Vol.11 No.4

애프터서비스와 같은 구매 후 고객에게 제공되는 제품관련 서비스의 중요성이 점차적으로 증가되고 있음에도 불구하고 그 동안 애프터서비스품질에 관련된 연구는 매우 부족한 실정이었다. 이에 본 연구에서는 내구소비재를 중심으로 애프터서비스의 품질이 서비스가치, 만족, 브랜드애호도에 미치는 효과를 알아보고자 하였다. 이를 위해 대도시 소재 애프터서비스를 이용한 경험자를 대상으로 설문을 조사하여 213부의 설문지가 최종분석에 사용되었다. 분석결과에 의하면 첫째, 애프터서비스 이용자들의 애프터서비스에 대한 전반적 품질 평가는 문제해결, 확신성, 편의성, 신뢰성의 영향을 받는 것으로 나타났고 그 중에서도 문제해결이 가장 크게 영향을 미치는 것으로 나타났다. 둘째, 전반적 애프터서비스품질은 애프터서비스에 대한 고객만족감과 서비스가치에 유의한 정(+)의 영향을 미치고, 애프터서비스에 대한 가치는 서비스만족에 유의한 정(+)의 영향을 미치는 것을 확인하였다. 셋째, 전반적 애프터서비스품질은 서비스에 대한 가치와 만족을 통하여 브랜드애호도에도 유의한 정(+)의 영향을 미치는 것으로 나타났다. 끝으로 이러한 연구결과를 바탕으로 애프터서비스에 관련된 관리적 시사점을 제시하였다. Even though the importance of product-related services provided to customers after the purchase is gradually increasing, there are few studies that focus on after-sales service. In this study, we investigate the effects of after-sales service, restricted to consumer durable goods, on service-value, satisfaction with the service, and brand loyalty. The data for this analysis was obtained from 213 consumers who used after-sales service for consumer durable goods in a metropolitan area. Our findings from analysis 1 and 2 are as follows: First, overall after-sales service perception is influenced by service components such as problem solving, assurance, convenience, and reliability. Specially, Analysis 1 indicates that problem solving has a stronger effect than others. Second, the overall after-sales service quality positively affects the satisfaction with the service and the service-value, which in turn positively influences the satisfaction with the service. Third, the overall after-sales service quality has a positive effect on the brand loyalty through the service-value and the satisfaction with the service. In addition, managerial implications related to after-sales service are suggested for practitioners.

韓國의 技術導入 評價에 관한 硏究

金完敏 釜山水産大學校 1994 論文集 Vol.50 No.-

The 1960s marked the take-off stage for Korea's industrialization. During this period, Korea was completely dependent on advanced countries for production facilities and technology. This was inevitable because domestic technological capabilities were very poor. But it was not easy to import foreign advanced technologies when domestic capabilities are extremely poor. Hence, the choice of appropriate technology to be adopted was a very important task for economic development, as well as for the development of science and technology. Choice of strategic industries for economic development was also affected by the possibility of success in technological adaptation. Hence, 1960s Korea promoted both import-substitution industries such as the energy, fertilizer and cement industries and export-oriented light industries. In the areas of science and technology, primary emphasis was on the importation of advanced technologies for solving problems which arose in these industries. The 1970s can be considered as the growth stage of Korean industrialization. During this period, emphasis was placed on laying the foundations of an industrialized country by fostering industries of higher level technologies than those promoted in the 1960s. These industries include machinery, materials, chemicals, shipbuilding and electronics. In the early 70s, great efforts were still being made to secure the foundation for scientific and technological growth. Fostering high quality scientists and performing basic research became urgent tasks for the 1980s, as the heavy and chemical industries became leading industries for economic development and high technology industries started to be spotlighted. While we must acknowledge the contributions of imported technology to the industrial development in Korea, it also made serious problem to the domestic economy in this period. For the last 30 years, Korea has fulfilled most of its technological needs with imports from Japan and U.S.A. Of the total purchases, imports from Japan and U.S.A. make up 77 per cent in terms of number of cases and 80 per cent in terms of costs. Especially, this reliance on Japan seems to have resulted from ; (ⅰ) expediency in communication, (ⅱ) geographical proximity and cultural and historical ties, (ⅲ) similarity in industrial structures, (ⅳ) limitations of information sources about the Western countries and (ⅴ) similarities in the environment of enterprise and their managerial conditions. However, excessive reliance on a particular nation for technologies generally aggravates existing technical dependency and economic subordination. With respect to the quality of technologies Korea imported from Japan, so far they are ; (ⅰ) "nonoriginal", (ⅱ) "declining" or, so to speak, of "standardized product state" in nature from the point of view of product life cycle, and (ⅲ) "secondary", introduced with the turn-key based technologies.

본 연구는 호텔산업 이용고객의 이탈의도에 영향을 미치는 요인의 규명을 목적으로 부산에 소재하는 특급호텔을 이용하는 고객을 대상으로 연구를 진행하였다. 그 결과 고객의 이탈의도를 방지하기 위한 실무적 모형이 도출되었으며, 본 연구의 주요결과는 다음과 같다. 첫째, 서비스품질의 구성요인이 고객만족에 미치는 영향관계에 있어서 모두 통계적으로 유의한 효과가 나타났으며 그 중에서 분위기의 영향이 가장 큰 것으로 나타났다. 추가적으로 고객이탈의도에 미치는 직접효과는 분위기를 제외한 종업원의 서비스와 식음료 상품 요인이 통계적으로 유의하게 나타났다. 둘째, 고객만족은 고객의 이탈의도에 직간접적인 영향이 나타났으며, 특별히 대안매력도를 낮추는 중요한 요인임을 확인하였다. 또한 이탈의도와 고객만족사이에서 기존연구에서는 대안매력도의 역할이 조절역할로 연구되어져 오던 것이 본 연구에서는 매개적 역할로 밝혀졌다. 마지막으로 이러한 결과를 통하여 실무적인 시사점과 향후연구에 대해서 간략하게 논의하였다. This study was intended to identify the major antecedent factors to customer satisfaction and then the structural relationships among customer satisfaction, attractiveness of alternatives, and customer intention to defect with the support of empirical evidence in the hotel restaurant. The research results may be summarized as follows. First, in the relationships between service quality and customer satisfaction, all the subconstructs of atmosphere, employee service, and food/beverage quality were found to be statistically significant. Atmosphere, employee service, and food/beverage quality were found to be major determinants in customer satisfaction, with atmosphere verified as the most influential one. Furthermore, employee service and food/beverage quality were found to have significant effects on customer intention to defect directly, but atmosphere was found not directly. Second, customer satisfaction was found to influence customer intention to defect directly and indirectly. Especially, customer satisfaction was identified as an important factor conductive to deterring customers from defecting indirectly by lowering attractiveness of alternatives. This finding verifies the role of attractiveness of alternatives as a mediating variable in contrast to its role suggested in prior research as a moderating variable between customer satisfaction and customer intention to defect. Finally, the implications of these findings and the future research directions are discussed.

Since the Political Economy of Marketing System was introduced by Arndt’s research in 1983, theoretical studies of relationship marketing have been accelerated. In particular, quantitative increase and specialization of channel behaviors in marketing channels have worsened channel-conflicts. As a result, more effective conflict management has been needed.Relationship marketing behaviors generated in marketing channels consist of bonds, cooperation, dependance, and so on. This research discussed how these relationship marketing behaviors affect the conflict and performance generated in marketing channels. The survey was conducted to purchasing managers and product managers as a distributor in marketing channels. It also focused on distributors in Busan, Korea.The results of this study are as follows: Distributors’ group revealed bonds, cooperation, comparison level for alternatives and dependance affect products-service conflict presented within this research. It also showed products-service conflict affected the satisfaction generated in marketing channels. It, however, revealed sales-conflict was influenced by bonds and dependance. That had no effect on satisfaction in marketing channels. These results were different from those of Lusch(1976) and Pearson(1973). Because most of prior literatures had researched with suppliers or dealers, this research tried to research the other side, distributors, in marketing channels. 본 연구는 관계마케팅에 대한 연구(Berry, Lynn, and Upah, 1983; Hakansson, 1982; Hallen, 1991; Jackson, 1985; Kotler, 1990 등)를 기반으로 관계마케팅과 관계마케팅 행동인 유대(bonds), 협동(cooperation), 의존성(dependence), 대체안의 비교(comparison level for alternatives)에 대한 이론적 배경을 알아보았다. 또한 유통경로 상에서 갈등에 관한 기존의 문헌연구를 알아 보았고, 이러한 이론적 바탕을 통해서 관계마케팅 요인과 갈등, 그리고 만족간의 인과관계를 실증분석 하였다. 자료의 수집은 부산 지역을 중심으로 백화점 및 할인점의 유통업자(Distributor)를 대상으로 관계마케팅 요인, 갈등, 그리고 만족에 관한 설문조사를 실시하였고, 수집된 자료를 바탕으로 구조방정식 모형을 사용하여 각 변인들 간의 인과관계를 파악하였다. 연구결과 제품·서비스 갈등은 유대, 협동, 대체안의 비교, 의존성에 영향을 받으며, 만족에 영향을 미치는 것으로 나타났으나, 영업 갈등은 유대와 의존성에만 영향을 받으며 만족에는 영향을 미치지 않는 것으로 나타났다. 이는 기존의 선행연구와는 다른 결과를 나타내어 유통업자 측면에서의 연구의 필요성을 제시하고 있다.
