평판 디스플레이가 사용되기 시작하면서 소형 전자기기인 모바일에서부터 TV와 같은 대형 전자기기까지 짧은 기간 동안 빠른 진보와 함께 인간의 시감을 통한 빠른 인지정보를 제공하는 형태로 발전의 비중이 높게 진행되고 있다. 이러한 발전 추세와 함께 디스플레이의 고해상도를 구현하기 위한 부품의 하나로 능동 소자형 기판과 같은 반도체 소자도 많은 기술적인 발전이 진행되어 왔으며, 응용 분야로 유기 박막 트랜지스터 (Organic Thin Film Transistors, OTFT) 연구도 많은 개발이 진행되어 왔다. 유기 박막 트랜지스터는 아직까지 게이트 절연체로 SiO2와 같은 무기물을 이용한 연구가 많이 진행되고 있는데, 이와 같은 무기물을 플렉서블(flexible) 디스플레이 등에 적용하기에는 한계가 있고 유기 트랜지스터의 이점을 살리기에는 충분하지 못하다. 이러한 한계점을 다소 극복하고자 간단한 공정을 이용하여 박막층을 유기물로 구현하기 위하여 플라스틱 기판의 특성을 플라즈마를 통한 계면 특성화를 활용하였으며, 고분자 물질을 용액화 하였다. 고분자 물질은 Poly-vinyl alcohol(PVA)과 Poly(9-vinyl carbazole)(PVK)를 사용하였다. PVA는 유전상수 값이 크고, 감광성 물질이며, 용매로 증류수를 사용하기 때문에 flexible 디스플레이에 쓰일 유기 박막 트랜지스터 제작에 유용하다. 그리고 Poly(9-vinylca -rbazole)(PVK)는 박막 형성이 잘 되고 HOMO-LUMO 밴드갭이 큰 물질로, 계면특성 향상을 위해 사용하였다. 또한, 가장 많이 쓰이는 소스-드레인(source/drain) 전극인 금(Au)을 비용 절감을 위해 니켈(Ni)과 은(Ag)를 사용하여 금과 유사한 성능을 보이는 소자를 제작하였다. As the interface properties were improved, it was remarkably developed the performance of organic thin film transistors (OTFTs). The basic electrical characteristics of OTFTs which adopted adhesion layer formed by solution process were investigated on the plastic substrate. It was found that PVK buffer layer promoted pentacene crystalline more densely packed than a bare pristine organic dielectrics, because of the characteristics for better morphology, smoother roughness, lower polarity and surface energy. The properties of the pentacene are closely correlated with the morphology of dielectrics and especially, in the case of PVK buffer layer, the roughness of dielectric is a critical factor for determining the growth of pentacene crystalline. Moreover, the surface energy and polarity have a strong influence on the growth of pentacene crystalline. The performances of OTFTs were improved by the modification of interface characteristics which has a more hydrophobic property and better morphology by inserting PVK adhesion layer. Moreover, Ag was suggested as source and drain electrode with Ni as an adhesion film for buffer layer and also as a hole injection film to pentacene layer in this presentation. Ag and Ni is currently available at production line for inexpensive and large size display. Top-contact pentacene TFT was fabricated using Ag as a source drain electrode and C-PVA film as a dielectric layer on the PES Plastic Substrates. To increase of mobility and improving stability between PES plastic Substrate between organic dielectric interface, oxygen plasma pre-reatment is processed. We have obtained a mobility value of about 1.52 cm2/Vs as saturation mobility, The on-off current ratio (Ion/off) is about 106 in a gate voltage span between 1 and -6 V while the drain voltage set at -5 V. It was also found that inexpensive Ag with Ni as a source and drain electrodes and PVK buffer layer can be applicable for fabricating pentacene TFT having a good elelctric characteristics. In this letter, we have demonstrated that Ag electrode itself as a S-D electrodes for OTFTs did not show good electrical characteristics. However, the insertion of the PVK buffer layer and Ni layer buffer layer conspicuously improved the electrical characteristics of OTFTs such as transfer and output characteristics. Moreover, we was found that oxygen plasma pre-reatment can be applicable for fabricating pentacene TFTs having good electrical characteristics. we suggested that commercialization and flexibility of driving circuit devices, the electrical characteristics of OTFTs which have bottom-contact and top-gate structures adopting organic thin film will be kept investigating in the future.

Since professor A. W. Shaw used the term "Logistics" for the first time in 1912, logistics have been changed into various figures mixed with commercial factors in point of viewpoint, shape, meaning. Especially, noticing the fact that a definition of logistics has had its meaning to be wide in proposition and field, whenever it went through particular alteration course, we can't overlook the question "Can we still define the accurate meaning of logistics?" Anyway, nowadays the definition of logistics include action of marketing, transport, storage, loading, packing, movement, and even the field of information act related, and the causes varied like this are logistic time-shortening, cost-reduction for ensuring of competitive advantage. Moreover, the environment of logistics was changed into the shapes of horizontal division, simplification of material resources security, phenomenon of blocking and globalization for ensuring this competitive advantage, ultimately the objectives of logistics were decided by two sides, service improvement for customers and economic operation of cost. The development of communication system and the accomplishment of consolidation of computer and all sorts of systems makes quickness, accuracy, maximization in quantity, and the establishment of outlook, production and sales plan by marketing information of multiple articles intended for more wide levels of customers is possible to us, and also easily outputting complicated logistics cost, we have come to promote rationalization of logistics. However, there happened huge cost in all kinds of organizations and management for logistics, and logistics standardization and logistics-sharing system appeared to correspond to these matters, and it has become a expanding trend gradually among international countries, same type of industries, different type of industries, firms by standardization and unitization. There are several conditions for the success of logistics unitization, and they may be desire for sharing, agreement, opportunity, environmental situation, administrative support. If these conditions would be activated through negotiation, enormous innovations would result through overall society. In this study, under the presumption these conditions had been satisfied I mentioned the unitization of logistics. We can expect the effects of concrete logistics unitization as follows ; reduction of logistics cost, improvement of loading percentage on transport, decrease of non-transport percentage by truck, shortening of movement, non-need for inspection of goods, reduction of facility investment, accuracy of charge system, simplification of calculation, relief of trafic congestion by one line transport system, rstionalization of business process, reduction of environmental contamination, reduction of social cost, improvement of logistics work productivity, improvement of financial status on logistics investent, improvement of efficiency by information system, maintenance and improvement of logistics service. But there are also serious problems as much as the big effect to activate logistics. Like to have been already written, there are problems such as difficulty of composition on participating company, differences in business information system, heterogeneity of firm culture, difficulty in negotiation among firms, matter of profitability by logistics system, keeping secrets, difficulty of service distinction, problem on the transport toll, and so on. But though there are a lot of troublesomeness, logistics unitification have been showing gradual progress, it is because that firms(for exemple, manufacturer, distributor, transporter)are raising the understanding on necessity of unitification step by step. There are successful propositions for firms as follows ; activation of joint transportation, establishment of joint logistics company, constrution of trustful relation among firms, buildup of business competitiveness by positive support on competent logistics firms, supplement of regulations and related laws on operational fund for business basis, appointment and support on wholesale and retail firms, standardization of internal equipment for logistics among companies, building of logistics facilities, administrative support, application of cross-talking form in transportation, establishment of joint transport system, relief of pass and parking restriction in fixed zone, and at the end buildup of cooperation system among distributors, manufactors, transporters. If the logistics system would be extended to this way, epoch-making logistics system breaking from existent system would be accomplished, and it is clear that this would make our many pressing problems solved out. Yet the understanding on joint logistics isn't in high level. But refered above, I expect that activation of joint logistics by increase of understanding would be not so long to be achieved. Therefore, from now on I anticipate that the way of logistics system would be renovated to more shape than now. Hopely this study would be useful to the purpose and many progressive studies to be achieved.

황선욱 인제대학교 보건대학원 2025 국내석사

목적 : 본 연구는 부산광역시 소재 요양병원 간병인 200명 대상으로 이들이 지각하는 상사의 서번트리더십이 조직시민행동(OCB)에 미치는 영향을 분석하고 감성지능의 조절효과를 실증적으로 규명함으로써 간병인들의 바람직한 조직행동 촉진을 위한 기초적 시사점을 산출하고자 하였다. 방법 : 연구모형은 서번트리더십을 청지기정신, 성장지원, 공동체형성, 비전제시의 네 차원으로 구성하고, 간병인이 지각한 감성지능을 조절변수로 설정하였다. 자료는 구조화된 자기기입식 설문지를 활용하여 수집되었으며, 표본 크기는 G*Power 3.1.9.7로 산출하였다. 수집된 자료는 SPSS 29.0을 사용하여 기술통계, 상관관계 분석, 위계적 회귀분석을 수행하였다. 결과 : 분석 결과 서번트리더십 총합과 하위요인인 청지기정신은 감성지능 수준과 관계없이 간병인의 조직시민행동에 유의한 정(+)적 직접효과를 나타냈다. 반면 성장지원은 감성지능이 조절변수로 포함될 때에만 조직시민행동에 유의한 정(+)적 효과를 보였다. 조절효과 검증에서는 감성지능이 청지기정신 경로에서는 부(-)적으로, 성장지원 경로에서는 정(+)적으로 작용하여 두 요인 간 효과 방향이 상반되었다. 결론 : 이상의 결과는 요양병원 관리자 및 간호사가 간병인을 대상으로 청지기정신과 성장지원에 중점을 둔 서번트리더십을 실천할 경우 간병인의 자발적·헌신적 조직시민행동을 효과적으로 촉진할 수 있음을 시사한다. 아울러 간병인의 감성지능 수준은 이러한 리더십 효과를 결정짓는 핵심 조절요인으로 확인되었으므로 조직 차원의 리더십 개발 프로그램과 병행하여 간병인 대상 감성지능 향상 교육을 체계적으로 운영할 필요가 있다. 본 연구는 간병인을 대상으로 서번트리더십과 감성지능의 상호작용이 조직시민행동에 미치는 영향을 규명함으로써 돌봄 인력 관리 연구의 외연을 확장하고, 실무적·정책적 전략 수립에 기초자료를 제공하였다는 의의를 갖는다. Purpose : This study examines how caregivers’perceptions of supervisors’servant leadership influence their organizational citizenship behavior (OCB) in long-term care hospitals, and empirically tests whether caregivers’emotional intelligence (EI) moderates these relationships. The ultimate aim is to derive practical and policy implications for fostering positive OCB among caregivers.6 Methods : Self-administered questionnaires were distributed to 200 car egivers who had worked for at least six months in long-term care hosp itals located in Busan, Republic of Korea. The survey measured four se rvant-leadership dimensions—stewardship, growth support, community bu ilding, and vision—together with EI and OCB. The required sample size was calculated with G*Power 3.1.9.7, and the collected data were analy zed in SPSS 29.0. Moderation effects were assessed through hierarchical regression analysis. Results : Overall servant leadership, and stewardship in particular, ex erted significant positive direct effects on OCB irrespective of EI. Grow th support displayed a significant positive effect on OCB only when EI was included as a moderator. EI significantly conditioned the impact of stewardship and growth support on OCB in opposite directions: higher E I weakened the positive influence of stewardship, whereas it strengthen ed the positive influence of growth support. Conclusions : Servant-oriented behaviors by supervisors can enhance caregivers’ discretionary and committed OCB in long-term care hospit als; stewardship and growth support emerged as the most influential fac ets. Caregivers’ EI functions as a critical contingency, suggesting that leadership-development programs should emphasize stewardship and gro wth-support behaviors while concurrently providing EI-enhancement trai ning for caregivers. By clarifying the interactive effects of servant lead ership and EI among caregivers, this study broadens the scope of OCB research and offers actionable insights for healthcare managers and pol icymakers.

The purpose of the study can be divided into two main categories. First, it is to develop a player evaluation index for each position that can replace the existing player evaluation index used in the NBA. Second, based on this evaluation index, it is to develop an annual salary prediction model of players and provide objective evidence on the market value of players. A total of 400 athletes who digested the 2016-2017 season were analyzed based on season performance data. The main component analysis was used to solve the problem of high correlation among the 14 variables, and As a result, the competitor evaluation index of Guard, Forward and Center players were developed three each. In order to see the relationship between salary and salary using the developed competitor evaluation index, an annual salary evaluation model was developed using the regression analysis of main components. As a result, the C_1 variable in all position salary evaluation models could be identified as the variable that affects salary the most. Through this study, we were able to develop player evaluation indexes and annual salary evaluation models for each position, and if these results are applied in the KBL, we hope that they will contribute greatly to the value assessment market for professional basketball players.

황선욱 성균관대학교 미디어문화융합대학원 2020 국내석사

기업이미지가 기업의 성패를 좌우하는 시대다. 기업이미지 관리의 중요성은 아무리 강조해도 지나치지 않고, 기업은 긍정적인 기업이미지를 만들기 위해 다방면으로 노력한다. 본 연구는 기업이미지 관리를 위한 커뮤니케이션 도구 중에서도 ‘문화예술 스폰서십’에 대해서 분석하였다. 또한 ‘이미지 전이 효과’ 이론을 적용하여 그 효과를 확인하고, 문화예술 스폰서십에 참여하는 ‘후원 목적’과 ‘기업 유형’에 따라서 유의미한 차이가 있는지 비교하였다. 본 연구는 문화예술 스폰서십을 통한 이미지 전이 효과를 분석하기 위해 시나리오를 바탕으로 실험 연구 조사를 실시하였다. 후원 목적(영리적/비영리적)과 참여 기업유형(B2C/B2B)을 독립변인으로 하는 2×2 요인 설계방안으로 총 4그룹으로 나누어서 연구를 진행하였다. 총 320명을 대상으로 그룹별 80명씩 성별과 연령대를 동일하게 배분하여 실험처치물과 설문 문항을 통해서 스폰서십 정보 노출 전의 기업이미지, 행사 이미지, 스폰서십 정보 노출 후의 기업이미지를 측정하였다. 설문 항목의 신뢰도 분석을 실시하였고, 문화예술 스폰서십을 통한 이미지 전이 효과를 확인하기 위해서 스폰서십 정보 기사를 제공하기 전과 후 기업이미지와 행사이미지 간의 각 차이값으로 대응표본 t-test를 수행하였다. 또한 후원 목적(영리적/비영리적)과 기업 유형(B2C/B2B)에 따른 차이를 자세히 분석하기 위해서 각각의 조건별로 대응표본 t-test를 실시하였다. 이에 따른 연구 결과를 요약하면 다음과 같다. 첫째, 문화예술 스폰서십을 통해서 이미지 전이 효과가 일어나는 것을 확인하였다. 둘째, 문화예술 스폰서십을 통해서 세부 이미지 속성별로 행사이미지에서 기업이미지로 전이되는 효과가 발생한다. 셋째, 문화예술 스폰서십의 후원 목적이 비영리적일 때, 영리적인 경우에 비해서 상대적으로 이미지 전이가 더 유의한 효과를 나타내는 것을 확인하였다. 넷째, 문화예술 스폰서십에 참여한 기업 유형이 B2C 기업인 경우와 B2B 기업인 경우일 때 이미지 전이 효과에 있어 유의미한 차이가 나타나지 않았다. 위 결과를 종합했을 때, 기업이 문화예술 스폰서십의 특성을 전략적으로 고려하면 이를 주요한 마케팅 커뮤니케이션 수단으로써 활용할 수 있다는 사실을 확인하였다. 본 논문에서는 연구 결과를 통해 기업이 대중을 대상으로 기업이 지향하는 이미지를 구축하고자 할 때, 문화예술 스폰서십이 효과적인 도구가 될 수 있다는 점을 제시하였다. 이러한 결과를 종합하였을 때, 본 연구는 다음과 같은 의의가 있다. 첫째, 커뮤니케이션 이론 중 하나인 ‘이미지 전이 효과’를 ‘문화예술 스폰서십’에 대입해 분석한 연구 사례를 제시했다는 학문적 의의가 있다. 둘째, 기업 홍보/마케팅 담당자 및 문화예술 산업 분야 종사자에게 기업이미지 제고를 위한 실무적 시사점을 제공하였다. ‘문화예술 스폰서십’의 효과를 확인함으로써 기업의 브랜드 전략 수립 시에 검토 가능한 커뮤니케이션 도구를 제시하였다. 문화예술 스폰서십이 기업이미지에 미치는 영향을 이미지 전이 효과를 통해 분석한 본 연구는 이 같은 학문적, 실무적 의의를 지닌다고 볼 수 있다. Corporate Image dictates its rise and fall. The importance of corporate image management can never be overemphasized, and every business makes every effort to improve their corporate image. Among many communication tools for corporate image management, this study focuses on the concept of “Culture and Arts Sponsorship.” By applying the theory of “Image Transfer Effect,” the study verifies the effects of culture and arts sponsorship and compares whether its impacts on corporate image differ according to the “purposes of sponsorship” and the “types of business.” To test for the image transfer effect culture and arts sponsorship on corporate image, the study designed and conducted a survey based on a scenario. The survey was divided into four groups via 2 x 2 factor design method using a) the purposes of sponsorship (either for-profit or non-profit), and b) the types of business (either B2B or B2C) as independent variables. The study divided 320 respondents into sub-groups of 80, where their genders and ages are homogeneously distributed. Then the respondents were given experimental materials and questionnaires to measure the corporate image before disclosure of the sponsorship information, the event image and the corporate image after disclosure of the sponsorship information. Controlling for the validity of survey items, a paired-sample t-test was conducted on the difference of corporate and event image levels before and after providing articles about the sponsorship to verify the image transfer effect on culture and arts sponsorship. To understand the impact of the factor matrix (the purposes of sponsorship and the types of business) on the image transfer effect, the study conducted a paired-sample t-test of each factor. The findings can be summarized as follows; 1. Culture and arts sponsorship does trigger the image transfer effect, 2. Through culture and arts sponsorship, there is an effect where specific features of a certain image transfers from an event image to a corporate image, 3. The impact of image transfer is relatively more significant when the purpose of culture and arts sponsorship is for-profit than non-profit, and 4. The image transfer effects are not significantly different regarding the business type(B2B or B2C) of the sponsor. These findings imply that culture and arts sponsorship can serve as a strategic marketing communication tool in improving the public perception of corporate image. Concluding from the findings, the significance of this study is both academic and practical. The study provides an academic research case on empirically verifying the communication theory “Image Transfer Effect” via “Culture and Arts Sponsorship.” It also serves as a practical evidence for corporate marketers and culture and art industry workers on improving corporate image. “Culture and Arts Sponsorship” can now serve as a viable communication tool in development of branding strategies.
