  • We study the normality of families of meromorphic functions sharing a set consisting of two or three distinct finite values to improve and extend Theorem 1 in Liu-Pang [15] and Theorem 1.1 in Liu-Chang [16]. Examples are provided to show that the results in this paper, in a sense, are the best possible.

  • 본 연구의 결과, 공유리더십과 조직웰빙의 조직 내 인간관계에서는 지시적 공유리더십과 변혁적공유리더십이 정(+)의 효과를 나타내는 것으로 나타났다. 그리고 공유리더십과 조직웰빙의 직무보람과의 관계에서는 지식적 공유리더십을 제외한 나머지 3개의 공유리더십 유형이 정(+)의 효과를 나타내는 것으로 연구되었다. 또한 공유리더십과 조직웰빙의 조직분위기와의 관계에서는 변혁적 공유리더십과 위임형 공유리더십 유형이 정(+)의 효과를 나타내는 것으로 연구되었고 공유리더십과 조직웰빙의 삶에의 충일감과의 관계에서는 변혁적 공유리더십만이 정(+)의 영향을 주는 것으로 나타났다. 마지막으로 공유리더십과 조직웰빙의 삶의 여유와의 관계에서도 충일감과 마찬가지로 변혁적 공유리더십만 정(+)의 영향을 주는 것으로 나타났다. 결론적으로 변혁적 공유리더십은 조직적 차원의 웰빙과 개인적 차원의 웰빙에 고루 영향을 미치는 것으로 나타났다. 변혁적 공유리더십은 공통된 비전이나 전략을 세우거나 서로를 고무시켜 기존의 방식들을 변형시켜 나가는 것이다. 하지만 지시적 공유리더십은 대인관계에서만 영향을 미쳤고 거래적 공유리더십은 직무보람에만 영향을 미치는 것으로 검증되었다. 보다 명확하게 무엇을 해야 할 지에서 대하여 서로에게 의견을 제시하고 성과에 대한 보상을 공유한다는 것은 조직구성원들이 보다 보람을 느끼며 업무를 수행한다는 점을 시사한다.

  • Shared value enhances the competitiveness of a company while simultaneously reducing societal burdens. By allowing companies to share their resources, collaborative logistics systems provide companies with an opportunity to create shared value, namely, not only economic value by enhancing the utilization of resources, but also social value by reducing energy consumptions and greenhouse gas emissions associated with logistics and transportation. Emerging businesses, such as ES3 and Flexe, have recently demonstrated how they created shared value through collaborative logistics services, for example, ES3's collaborative warehousing and direct-to-store (D2S) program, and Flexe's on-demand warehousing platform. However, the development of collaborative logistics systems is currently at a nascent stage. There are quite a few socio-technical barriers to overcome for sharing resources (data as well as infrastructure). Drawing on the socio-technical approach, this research examines how companies create both economic and social value from collaborative logistics systems. We highlight socio-technical barriers, particularly one set of social barriers, that is, competition-oriented conservatism prevalent among companies. Using the case study methodology and interview data, we closely investigate ES3 and Flexe, which provide collaborative logistics services, and demonstrate how technical and social barriers are addressed to create shared value from collaborative logistics systems.

  • In this study, the shared facilities and space in the multi-family housing which residents could maintain contacts with their neighbors were investigated and analyzed. It could find the shared facilities and space so that residents could maintain to contact with their neighbors after surveying the dwellers requirements. Also it could specify the importance of the neighborhood common spaces and the conditions for the planning of the shared facilities. Analyzing residents requirement of set-up location, this study lead to the following suggestions concerning the facilities design: In the first neighborhood-circle, it require to be related the household affairs of housewives on the adjacent space to a dwelling-unit. In the second neighborhood-circle, it require especially the facilities for children play, study, reading, hobby etc. These facilities need establish each 4-5 floor in high-rise building estates. The roof & underground floors has been recognized in important & essential place for living facilities. Therefore, it is needed to improve to get ready to receive the various facilities.

  • To enable hard real-time systems to take advantage of multicore processors, it is crucial to obtain the worst-case execution time (WCET) for programs running on multicore processors. However, this is challenging and complicated due to the inter-thread interferences from the shared resources in a multicore processor. Recent research used the combined cache conflict graph (CCCG) to model and compute the worst-case inter-thread interferences on a shared L2 cache in a multicore processor, which is called the CCCG-based approach in this paper. Although it can compute the WCET safely and accurately, its computational complexity is exponential and prohibitive for a large number of cores. In this paper, we propose three counter-based approaches to significantly reduce the complexity of the multicore WCET analysis, while achieving absolute safety with tightness close to the CCCG-based approach. The basic counter-based approach simply counts the worst-case number of cache line blocks mapped to a cache set of a shared L2 cache from all the concurrent threads, and compares it with the associativity of the cache set to compute the worst-case cache behavior. The enhanced counter-based approach uses techniques to enhance the accuracy of calculating the counters. The hybrid counter-based approach combines the enhanced counter-based approach and the CCCG-based approach to further improve the tightness of analysis without significantly increasing the complexity. Our experiments on a 4-core processor indicate that the enhanced counter-based approach overestimates the WCET by 14% on average compared to the CCCG-based approach, while its averaged running time is less than 1/380 that of the CCCG-based approach. The hybrid approach reduces the overestimation to only 2.65%, while its running time is less than 1/150 that of the CCCG-based approach on average.

  • In this paper, we study a problem of a non-constant entire function f that shares a set S = {a, b, c} with its k-th derivative f(k), where a, b and c are any three distinct complex numbers. We have found a gap in the statement of the main result of Chang-Fang-Zalcman [10], and with the help of their method, we have generalize their result in a more compact form. As an application, we generalize the famous Brück conjecture [9] with the idea of set sharing.

  • This study is a preliminary study to develop design guidelines on shared spaces of apartment for healthy housing. It was tried to set the basic direction of the guideline development by comparing and analyzing related literatures based on the previously identified evaluation indicators of healthy housing of apartment. The major findings were as followings: 1) based on the research conducted before, the characters of shared spaces for healthy housing were classified as physical, mental and social dimensions. 2) According to the comparison and analysis of relevant standards and guidelines, focuses were mostly on the physical dimension, particularly on the human traffic lines of the convenience attributes. Other focuses were on the attractiveness of the apartment complex of the vitality attribute under the mental dimension, and community facilities of the residential stability attributes under the social dimension. Therefore, it was identified that it is required to take complementary measure regarding mental and social dimensions, and design concrete steps to include different attributes of each dimension, in order to develop comprehensive guidelines for shared space.

  • For a value s ∈ ℂ∪ {∞}, two meromorphic functions f and g are said to share the value s, CM, (or IM), provided that f(z)-s and g(z)-s have the same set of zeros, counting multiplicities, (respectively, ignoring multiplicities). We say that a meromorphic function f shares s ∈ Ŝ partially with a meromorphic function g if E(s, f) ⊆ E(s, g). It is easy to see that "partially shared values CM" are more general than "shared values CM". With the help of partially shared values, in this paper, we prove some uniqueness results between a non-constant meromorphic function and its generalized differences or shifts. We exhibit some examples to show that the result of Charak et al. [8] is not true for k = 2 or k = 3. We find some gaps in proof of the result of Lin et al. [24]. We not only correct these resuts, but also generalize them in a more convenient way. We give a number of examples to validate certain claims of the main results of this paper and also to show that some of conditions are sharp. Finally, we pose some open questions for further investigation.

  • 본 연구는 아웃도어 브랜드 소비자의 소비가치와 기업의 공유가치창출활동이 소비자의 구매의도에 미치는 영향을 실증적으로 분석하였다. 소비자의 구매의도에 미치는 영향요인으로 소비가치의 하위변수는 기능적 가치, 상황적 가치, 감정적 가치로 설정하였고, 기업의 공유가치창출활동의 하위 변수는 경제적 가치, 관계적 가치, 사회적 가치로 설정하였다. 분석결과, 소비가치의 기능적 가치, 상황적 가치, 감정적 가치는 구매의도에 긍정적인 영향을 미치는 것으로 분석되었고, 기업의 공유가치창출활동의 경제적 가치, 사회적 가치, 관계적 가치도 모두 긍정적인 영향을 미치는 것으로 분석되었다. 분석결과에 따라 아웃도어 브랜드 소비자의 소비가치와 기업의 공유가치창출활동은 모두 구매의도에 긍정적인 요인으로 작용하고 있음을 알 수 있었다. 이러한 결과는 아웃도어 브랜드 산업에서 소비자의 소비가치나 기업의 공유가치창출활동은 이미 소비자의 구매의도에 충분히 반영되었다고 추론할 수 있었다.
