  • Drawing on literatures from communication strategy and human resource management, this study examines how perceived communication satisfaction can affect turnover intention and also figure out mediating effect through affective commitment. We analyzed a data set from one of the largest government organizations in health and medical treatment including 267 employees's sample. Apart from previous studies, this study emphasizes perceived communication satisfaction is a critical factor rather than communication policies. Also, affective communication partially mediates the relationship between perceived communication satisfaction and turnover intention. Our theory and findings provide new insight into human resource management field in growing Korean organizations.

  • A block Jacket transform and. its block inverse Jacket transformn have recently been reported in the paper 'Fast block inverse Jacket transform'. But the multiplication of the block Jacket transform and the corresponding block inverse Jacket transform is not equal to the identity transform, which does not conform to the mathematical rule. In this paper, new binary block Jacket transforms and the corresponding binary block inverse Jacket transforms of orders $N=2^k,\;3^k\;and\;5^k$ for integer values k are proposed and the mathematical proofs are also presented. With the aid of the Kronecker product of the lower order Jacket matrix and the identity matrix, the fast algorithms for realizing these transforms are obtained. Due to the simple inverse, fast algorithm and prime based $P^k$ order of proposed binary block inverse Jacket transform, it can be applied in communications such as space time block code design, signal processing, LDPC coding and information theory. Application of circular permutation matrix(CPM) binary low density quasi block Jacket matrix is also introduced in this paper which is useful in coding theory.

  • In a cellular mobile communication control system, assignment channel for a call in a cell so as to achieve high spectral efficience is an important problem within limited frequence bandwidth. The spectral efficiency is related to the coloring problem of graph theory in a cellular mobile communication control system. In this paper, we propose channel offset scheme using a graph theory of cellular mobile communication control system and formulate chromatic bandwidth of channel offset system which is related graph coloring problem. From formulated channel assignment problem, we investgate an optimal channel offset scheme of more efficent frequence spectrum and cell design according to channel constitution and give and upper and lower bound for overall srectral bandwidth.

  • The spectrum allocation is an attractive issue for mobile cognitive radio (CR) network. However, the time-varying characteristic of the spectrum allocation is not fully investigated. Thus, this paper originally deduces the probabilities of spectrum availability and interference constrain in theory under the mobile environment. Then, we propose a prediction mechanism of the time-varying available spectrum lists and the dynamic interference topologies. By considering the node mobility and primary users' (PUs') activity, the mechanism is capable of overcoming the static shortcomings of traditional model. Based on the mechanism, two prediction-based spectrum allocation algorithms, prediction greedy algorithm (PGA) and prediction fairness algorithm (PFA), are presented to enhance the spectrum utilization and improve the fairness. Moreover, new utility functions are redefined to measure the effectiveness of different schemes in the mobile CR network. Simulation results show that PGA gets more average effective spectrums than the traditional schemes, when the mean idle time of PUs is high. And PFA could achieve good system fairness performance, especially when the speeds of cognitive nodes are high.

  • This study is on theoretical foundation for orthodoxy korean style Environmental Education based on oriental ecological thought. The main theme is that various kinds of all the ideas related with ecological thought based on oriental thoughts for EE should be focused into Moderation, the core-concept of oriental confuscian thoughts. The Moderation has not meant just a personal enlightenment, as it has known to general people, it can be developed into social status core-consciousness for regulating the natural resource. So we should focus on this conceptual developing mechanism personal enlightenment into social status for our orthodoxy konean style EE. It can be infered from Taoism, Confuscionism Buddism, especially, Anxiety Consciousness (WOOHWAN) for grand-scale anxiety to public society and universal cosmos. And also I drawed Harbermas-philosophy to provide good means for fortifying this research. His communication theory and restoration of real life for public people communication can be connected to oriental thoughts in the aspect of reciprocative response among the community people. So our orthodoxy korean style EE can be erected on the community-based regionality and their public communication through reciprocative response process. We should try to make this surrounding conditions nature-familiar oriental philosophy has provided from ancient times in the aspect all the traditional thought has been eco-deterministic.

  • As the common saying attests, a publish-or-perish world, publishing is absolutely critical for academic researchers' successful careers. It is the most objectively-accepted academic performance criteria and the most viable way to attain public and academic recognition. Asia Pacific Journal of Information Systems(APJIS) has been recognized as the most influential domestic journal in Korean MIS field since July, 1991. Therefore, publishing in APJIS means your research is original, valid, and contributive. While most researchers learn how to publish an article in APJIS through a repetitive review process, thereby improving their chance of the' accepted' through their personal trial and error experiences, such valuable lessons and know-how tend to be kept personally and rarely shared. However, useful insights into research and publication skills could be also gained from sharing others' errors, neglect, and misjudgments which are equally critical in improving researchers' knowledge in the field (Murthy and Wiggins, 2002). For this reason, other academic disciplines make systematic efforts to examine the paper review process of major journals and share the findings from these studies with the rest of the research community members (Beyer et al., 1995; Cummings et al, 1985; Daft, 1995; Jauch and Wall, 1989; Murthy and Wiggins, 2002). Recognizing the urgent need to provide such type of information to MIS research community in Korea, we have chosen the most influential academic journal, APJIS with an intention to share the answer to the following research question: "What are the common problems found in the manuscripts either 'rejected' or 'required a major revision' by APJIS reviewers?" This study analyzes the review results of manuscripts submitted to APJIS (from January, 2006 to October, 2008), particularly those that were 'rejected' or required a 'major revision' at the first round. Based on Daft's(1995) study, twelve most-likelihood problems were defined and used to analyze the reviews. The twelve criteria for classification, or "twelve problems", are as follows: No theory, Concepts and operationalization not in alignment, Insufficient definition--theory, Insufficient rationale--design, Macrostructure--organization and flow, Amateur style and tone, Inadequate research design, Not relevant to the field, Overengineering, Conclusions not in alignment, Cutting up the data, and Poor editorial practice. Upon the approval of the editorial board of APJIS, the total 252 reviews, including 11 cases of 2005 and 241 cases from July, 2006 to October, 2008, were received without any information about manuscripts, authors, or reviewers. Eleven cases of 2005 were used in the pilot test because the data of 2005 were not in complete enumeration, and the 241 reviews (113 cases of 'rejection' and 128 ones of 'major revision') of 2006, 2007, and 2008 were examined in this study. Our findings show that insufficient rationale-design(20.25%), no theory(18.45%), and insufficient definition--theory(15.69%) were the three leading reasons of 'rejection' and 'major revision.' Between these two results, the former followed the same order of three major reasons as an overall analysis (insufficient rationale-design, no theory, and insufficient definition-theory), but the latter followed the order of insufficient rationale--design, insufficient definition--theory, and no theory. Using Daft's three major skills-- 'theory skills', 'design skills', and 'communication skills'-- twelve criteria were reclassified into 'theory problems', 'design problems', and 'communication problems' to derive more practical implications of our findings. Our findings show that 'theory problems' occupied 43.48%, 'design problems' were 30.86%, and 'communication problems' were 25.86%. In general, the APJIS reviewers weigh each of these three problem areas almost equally. Comparing to other disciplines like management field shown in Daft's study, the portion of 'design problems' and 'communication problems' are much higher in manuscripts submitted to the APJIS than in those of Administrative Science Quarterly and Academy of Management Journal even though 'theory problems' are the most predominant in both disciplines.

  • Objective : This study began with a recognition of the increase in internal disorders caused by functional impairment of the Spleen-Stomach(脾胃) due to modern dietary culture and environment. Method : Way of studying is select and analysis sentences which is include 'Stomach-Yin(胃陰)', 'Stomach-Jin(胃津)', 'Spleen-Stomach-Yin(脾胃陰)', 'Stomach-Yang(胃陽)', 'Spleen-Stomach-Yang (脾胃陽)' in Imjeungjinamuian(臨證指南醫案), and organize relevant paper. Result & Conclusion : In the history of the Spleen-Stomach Theory(脾胃學說), the theoretical mainstream was focused on On-yang(溫養), which was supplemented with methods of sweeten-cool-moisturize(甘凉濡潤) and communication-descent(通降法) by Ye, Tianshi(葉天士). Ye, Tianshi followed the academic theory of Li, Dongyuan(李東垣), putting emphasis on Stomach-gi(胃氣), along with some unique developments of his own. He specifically argued that the Spleen and Stomach be treated separately, and while accepting the methods of Li Dong-yuan in Spleen treatment, asserted that the Stomach-Yin be treated with medicinals with sweet/plain and sweet/cool/moist(甘平與甘凉濡潤) characteristics, and Stomach-Yang be kept firmly, as to prevent obstruction and reflux, by means of medicinals that communicate the Yang softly(通陽柔劑). As a result, the Yin-Yang(陰陽), Dryness-Dampness(燥濕) and Cold-Heat(寒熱) balance of the Yin-Jang (陰臟), Spleen and the Yang-Bu(陽腑), Stomach, the Stomach-Yin and Stomach-Yang was achieved both theoretically and in treatment by means of both communication and supplementation, adding accuracy to clinical application of the Spleen-Stomach Theory.

  • Development of 5th generation mobile telecommunication technology is visualizing ideal hyper-connected social information and communication technology (ICT). In particular, virtual reality (VR) technology is at the starting point for new expansion and leaps. This work defines virtual reality as media in this context and collects and analyzes discourse on its scalability around space and communication theory. We first elaborated the concept, starting with the early discussions of the virtual reality concept in 1990, and discussed the relationship between the physical world and digital information, expression and interaction immersion as a medium, simulation, art creation theory, and finally evolutionary development. In conclusion, beyond the discourse on the technology of virtual reality, academic subjects were required to have theoretical frameworks on cognitive science, neuroscience, social science, and humanities issues (ethics, personality, etc.) for the development and evolution of virtual reality. In other words, it is time for the evolution of virtual reality to be discussed, which can be moved beyond.
