지식경영 전략과 기업성과 간의 실증연구는 연구자에 따라 그 결과가 매우 다르게 나타나고 있다. 이러한 연구결과의 불일치는 실제 비지니스 환경하에서 대다수의 기업은 다양한 지식경영 전략들을 동시에 활용하고 있음에도 불구하고 대다수의 기존의 연구는 개별 지식경영 전략과 기업성과간의 관계에만 초점을 두고 있었기 때문이다. 본 연구는 이와 같은 문제점을 해결하기 위해 경제학이론 가운데 하나인 상호보완이론(complementarity theory)을 기반으로 지식경영 전략들 간의 상호보완관계를 파악하고 이러한 상호보완관계가 기업성과에 미치는 영향을 전체적인 관점(holistic perspective)으로 분석하고자 한다. 이를 위해, 기존 연구를 바탕으로 지식경영 전략을 도출하였으며 국내 139개의 대기업을 기반으로 실증연구를 수행하였으며 이를 통해 지식경영 전략 간의 상호보완관계가 기업성과에 미치는 영향을 분석하였다. 학문적 측면에서 보면 본 연구는 경제학으로부터 새로운 이론과 분석방법론을 도입함으로써 기존 연구의 한계를 극복할 수 있는 새로운 연구 프레임웍과 방법론을 제시하였으며 이를 통해 지식경영 연구의 지평을 넓힐 수 있을 것으로 기대된다. 실무적 관점에서 보면 기업성과를 향상시킬 수 있는 다양한 지식경영 전략들 간의 상호보완관계를 제시함으로써 경영자에게 효과적인 지식경영 전략을 구축할 수 있는 가이드라인의 역할을 할 수 있을 것으로 기대된다.

본 논문에서 비구조적 피어투피어 망을 위한 적은 검색 시간을 가지는 최적화된 위상을 구성하는 분산된 위상 제어 알고리즘을 제안한다. 각 노드는 높은 검색 적중률을 가지는 최적의 노드들을 노드 자신의 적중률에 지수적으로 비례하는 수만큼 선택하고, 그들과 연계한다. 총체적 거동은 자연계에서는 볼 수 있는, 각 입자의 에너지 준위에 따라 입자들이 결합되는 재결정 현상과 결과적으로 거의 유사하다. 구성된 위상의 노드들의 적중율들 사이에는 부분 순서(Partial-order) 관계가 있다. 그러므로, 질의 메시지가 노드를 방문하는 경우에, 그 노드는 항상 직전에 방문하였던 노드들 보다 더 높은 적중률을 가지고 있다. 또한, 무위도식(Freeloader) 노드로부터 보내진 질의 메시지는 한 홉 전달에 의해, 무위도식하지 않은 노드들로 전달될 수 있고, 그것은 다시는 무위도식하는 노드들을 방문하지 않는다. 이처럼 검색은 제한된 지연시간 안에 이루어진다. 또한, 본 논문에서는 이 위상을 활용하여 효과적인 연쇄반응적 검색 방법을 제안한다. 그러한 제어된 다중 전송 방식은, 방송을 사용하는 방식 보다 질의 메시지들의 수를 43 퍼센트만큼 줄이며, 검색시간을 94 퍼센트 절감한다. 제안된 방안의 검색 성공률은 99 퍼센트이다.

Objective: This paper presents additional considerations related to organization and safety culture extracted from recent human error incidents in Korea, such as station blackout(i.e., SBO) in Kori#1. Background: Safety culture has been already highlighted as a major cause of human errors after 1986 Chernobyl accident. After Fukushima accident in Japan, the public acceptance for nuclear energy has taken its toll. Organizational characteristics and culture became elucidated as a major contributor again. Therefore many nuclear countries are re-evaluating their safety culture, and discussing any preparedness and its improvement. On top of that, there was an SBO in 2012 in the Kori#1. Korean public feels frustrated due to the similar human errors causing to a catastrophe like Fukushima accident. Method: This paper reassesses Japan's incidents, and revisits Korea's recent incidents. It focuses on the analysis of the hazards rather than the causes of human errors, the derivation of countermeasures, and their implementation. The preceding incidents and conclusions from Japanese experience are also re-analyzed. The Fukushima accident was an SBO due to the natural disaster such as earthquakes and a successive tsunami. Unlike the Fukushima accident, the Kori#1 incident itself was simple and restored without any loss and radioactive release. However, the fact that the incident was deliberately concealed led to massive distrust. Moreover, the continued violation of rules and organized concealment of the accident are serious signs of a new distorted type of human errors, blatantly revealing the cultural and fundamental weakness of the current organization. Result: We should learn from Japanese experiences who had taken pride in its safety technology and fairly high confidence in safety culture. Japan's first criticality accident in JCO facility splashed cold water on that confidence. It has turned out to be a typical case revealing the problems in the organization and safety culture. Since Japan has failed to gain lessons and countermeasure, the issue persists to the Fukushima incident. Conclusion: Safety culture is not a specific independent element, which makes it difficult to either evaluate it properly or establish countermeasures from the lessons. It may continue to expose similar human errors such as concealment of incident and manipulation of bad data. Application: Not only will this work establish the course of research for organization and safety culture, but this work will also contribute to the revitalization of Korea's nuclear industry from the disappointment after the export contract to UAE.

Purpose - This study reviews the achievements of a pilot project for the revitalization of a commercial district performed for three years after its establishment in 2011. The project for the revitalization of the commercial district was performed to create a new local community space in connection with the traditional market and nearby districts. Although it was a pilot project, the project for the revitalization of the commercial district has been performed for almost three years. Therefore, this seems a proper time to conduct an interim evaluation of the project. This study aims to review and evaluate how the government support policy is influential for the revitalization of the commercial district. In other words, this research aims to identify what projects positively affected consumers' intention to revisit the downtown commercial area among the commercial district revitalization projects-promotion events, promotion activities, education, merchants cooperation system, IT projects, cultural events, and residents' communication. Research design, data, and methodology - This study designated seven management improvement projects affecting commercial district revitalization based on preceding studies. The survey of the degree of satisfaction on seven management improvement projects was executed targeting consumers who visited the commercial areas. Additionally, visitors' revisit intentions regarding currently visited commercial areas were also investigated. Therefore, revisit intention was set as a dependent variable and the satisfaction degrees of the respective management improvement projects were set as the independent variables. A total of 1,209 consumers were examined in six districts in the country. Result - Multiple regression analysis results showed that cultural events, education, the merchants' cooperation system, and IT projects brought statistically significant effects to the revisit intentions of consumers. In contrast, promotion events, resident communication projects, and promotion activities did not affect the revisit intentions of consumers. Particularly, the residents' communication project did not show significant influence because of consumers' recognition that it is similar to a cultural event. Conclusion - The following implications for the revitalization of business districts in the urban central area are drawn. From a general perspective, the businesses of culture, education, and cooperative system among seven businesses play positive roles regarding the intention to revisit so that the project is required to be promoted periodically through unique performances differentiated for each district, the merchant training reinforced for professionalism, and the expansion of joint events of merchants. Moreover, the sales promotion project and public relations activity are shown to be not influential to the intention to revisit. Therefore, while short-term sales promotion such as one-time gift events are required, sales promotion and public relation activities to induce revisits by mileage savings and accumulated gift presentation to attract long-term customers are required. The IT business is positively influential to the intention of revisit. Therefore, detailed information on the revitalized commercial district should be provided and additional functions such as discount coupons for continuous utilization should be included in the mobile app and the website.

Objectives : In this study, the dental treatment satisfaction degree of the patients, who experienced the sleep dental treatment or non-sleep dental treatment, the revisit rate and the differences among the encouraging intention were compared and analyzed, and the primary factors through which the satisfaction degree of sleep dental treatment has influence on the revisits and the encouraging intention were analyzed, and the proposal was made on clinic management to raise qualitative medical service level on the basis of this study. Methods : The questionnaires filled out by the 202 users of a certain dental clinic located in Pohang-si, Gyeongbuk were analyzed. The frequency analysis and the crosstabulation analysis of the general characteristics of survey participants were carried out, and the satisfaction difference between the sleep dental treatment and the non-sleep dental treatment was identified with the t-test analysis. The multiple regression analysis were carried out to identify the factors through which the sleep dental treatment has influence on the through which the satisfaction degree of sleep dental treatment has influence on the satisfaction degree of the medical service and the revisited dentists. Results : In the medical service satisfaction degree in general, the sleep dental treatment had the higher meaningful value than the non-sleep dental treatment(p<0.05). In the case of the difference in satisfaction degree on each medical service factor, the satisfaction of the sleep treatment group was high in every case, but the meaningful difference showed up in the factors of waiting time, treatment procedure, revisit and the encouraging intention(p<0.01). The revisit to the sleep treatment dental clinic and the recommending dentist increased in proportion to the satisfaction degree of sleep dental treatment, and the Beta value appeared to be 0.337 at the influence of the subordinate variable(p<0.001). As for the influence on the sleep dental treatment satisfaction, the Beta value of the dental hygienist was the highest, marking the value at 0.375(p<0.01). As for the satisfaction of the patients who experienced the sleep dental treatment, the Beta value of the treatment fee was the highest, marking 0.352(p<0.001), in the multiple regression analysis of the revisit and the encouraging intention, and the 0.156 of dentist factor and the 0.152 of treatment procedure and waiting time showed lower regression coefficient(p<0.05). Conclusions : It is assumed that the satisfaction degree of sleep dental treatment, which is carried out as a new dental service has influence on the increase of revisit to the dental clinic as an important factor. But it was disclosed that the high level of treatment fee has the biggest influence on choice of revisit to the dental clinic. In the current medical charge system, the sleep dental treatment appeared to have a big influence on raising the quality of dentists, the satisfaction of patients, the revisit and encouraging intention, and also the roles of the dental hygienist was important. It is assumed that these facts are functioning as the factors that are linked to the increase of revisit and the encouraging intention.

Due to the remarkable changes in the early twentieth century, the new invention and technology impacted peoples' everyday lives and people started to use the word, modern, to apply specifically to what pertained to present times and to designate a movement in what was new and not old-fashioned-a condition of newness. In the present day, however, the fantastic cultural changes of a century ago have now become commonplace, and what was once considered radically new is no longer a reason to marvel. This paper considers what it mean to be modern, once the new is no longer new. This question seems to remain as complicated and inappropriate to ponder because the consideration and impact of modernity cannot simply end with the end of an era. This paper investigates how the interconnected nature of popular culture provides apt illustrations to reveal the ambivalent nature of modernity and postmodernity. In doing so, first of all, this paper pays attentions to the notion of modernity and popular culture which emerged together in the early twentieth century when technology and mass consumer culture were promoted over the world. Also, it examines how popular culture represents a complex of mutually-interdependent perspectives and values that influence society and its institutions in various ways as the image of modernity continues to build in a postmodern era. That is, popular culture is identified as a large amount of intertextuality or collective experiences due to its intermingling of complementary distribution sources and techonology. Thus, this paper explores that popular culture devotes itself other images or narratives instead of referring to the real world and its output revisits the contemporary or past times in other places, being a means to produce and reproduce the accumulated images of the modern which shapes ceaseless simulacra of modernity over complexities of modernity. In order to find a critical juncture of the complex networks of modernity and popular culture, this paper considers two places, Chicago and Gyeongsung in the 1920s and 1930s in which the rapid modern experience took place and the modern movement forced the two societies to join the mass consumer culture whether willingly or not. Next, this paper considers two movies released in 2002 and 2008 that exemplify the complexities of modernity in Chicago and Gyeongung of the 1920s and 30s: Chicago and Modern Boy. Both films have common themes of the 1920s and 30s such as violence, adultery, femme fatal, and criminal themes with the forms of musical, dance, drama, and romance. Through the textual analysis of both Chicago and Modern Boy, two films are compared in observing the similar and different ways in which two films deal with the theme of modernity when they are represented from the contemporary perspectives. More specifically, this paper questions how modernity is present in contemporary cultural forms such as commercial and hybrid genre films; and how these movies create a new image of modern by embodying the double coding. Ultimately, this paper aims at realizing the paradox of double edged modernity and its ongoing discourse that controls people's consciousness through the medium of popular culture.
