In this paper, the method to miniaturize the radiating element of a VHF-band active electronically scanned array is proposed. The length of the proposed dipole having trapezoidal shape structure is miniaturized using meander line while the performance degradation is minimized. The grid reflector is used to improve the antenna directivity and insensitivity due to the outer environment. In addition, the antenna is designed to take into account for array application. The fabricated antenna has a 9.1 % fractional bandwidth for the voltage standing wave ratio(VSWR) 2:1 and the maximum gain of 4.24 dBi. The front-to-back ratio(FBR) is larger than 15 dB.

The purposes of this study were firstly to reveal the sub-dimensions of time management behaviors and secondly to group workers by time management behaviors. The major findings of this study were as follows. (1)Factor analysis of the 36 items on the time management behaviors instrument revealed three components: factor planning, relations-intention, and urgency. (2)Workers were categorized into four types by the level of those three factors of time management behaviors: 'accomplishment type'($28.31\%$), 'chronic-urgency type'($24.39\%$), 'valuing-job type'($23.73\%$) and 'valuing-human relations type'($23.57\%$). (3)The accomplishment type gained the highest points on the time management satisfaction score, and the level of important${\cdot}$non-urgencies was the highest score, indicating that the accomplishment type had good time management. However, the level of unimportant${\cdot}$urgencies was the highest score. Therefore, this type should try to reduce the level of unimportant${\cdot}$urgencies.

Good salespeople are the deciding factors in the success of an organization. In particular, the role of the salesperson takes on a more important role. Accordingly, the first purpose of this study is to understand the personal values of salespeople; secondly, to study the explanation personal values, adaptability, and customer orientation have on salesperson's performance. The third purpose is to understand the structural link among each of the explanatory factors related to salesperson performance. Lastly, with these research results as a foundation, to find the implications regarding management strategy plans of valuable salespeople for marketing researchers and sales managers.

Despite the recent increase in the prevalence of the franchise system in the foodservivce industry is increased recently, the its variation the exigencies of the industry itself requires that franchise systems to be fully equipped with various a variety of business strategies which is indispensable to run franchise system. In the previous studies, most the majority of researchers have been likely to gathered samples from only one region, or all from a similar type of business. However, considering the difference between Seoul and other areas or categories of business type, there could be may be differences different with in these conditions (market orientation, transaction specific assets, environmental dynamic, and trust and trust). Therefore, the principal objective of this study aims was to verify the differences among areas and categories of franchise business. The results of this article are as follows : the variables of customer orientation, competitor orientation, environmental dynamics, and trust and transaction- specific assets show evidence regional differences (p<0.01), and these variables are differ significantly different by category of business (p<0.05). However, the present paper is limited in its scope. Further studies on into different largesclae assessments are needed required.

The purpose of this study is to establish theoretical basis for relationship marketing exercised in the esthetic industry and to empirically analyze causal relationship among factors of esthetic relationship marketing, together with quality and the performance of the relationship. With empirical research, this study finds out that such relationship marketing factor as customer orientation, employee' expertise, physical property have an impact on the relationship quality between customers and esthetic salons' service providers. Customer satisfaction and trust increase the relationship between service providers and customers, and this also increases repurchase intention of the customer towards the service providers. These are significant findings in that they illustrate the importance of employee' expertise and customer orientation, and physical property in determining satisfaction and trust. The result of this study shows that service providers can enhance customer satisfaction and trust by utilizing relationship marketing more effectively, and can preserve the current customer basis.

A new algorithm for frequency channel assignment in high capacity cellular mobile communication systems is proposed. The algorithm is the advanced type of the fixed channel assignment scheme. It enables calls having all nominal channels busy to be served by adjacent cells have idle channels. Thus, it considerably reduces the blocking probability compared with the fixed channel assignment. Simulation has been performed for a 49-cell system having uniform traffic density hexagonal array as a representative system lay out. Results showed that new algorithm is better than the fixed channel assignment scheme in high capacity cellular mobile communication systems.

The purpose of this study is to examine the effect of logistics service quality and relationship orientation factors on customer satisfaction and loyalty in the electronic commerce context. Based on extensive review of relevant literature, nine components of logistics service quality(i.e. information quality, ordering procedures, ordering release quantities, timeliness, order accuracy, order quality, order condition, order discrepancy handling and personnel contact quality) and six components of relationship orientation(i.e. trust, bonding, communication, shared value, empathy and reciprocity) are introduced in this study. And a conceptual model is developed and five research hypotheses are empirically examined using structural equation modeling. The findings indicate that logistics service quality and relationship orientation are positively and significantly associated with customer satisfaction, and customer satisfaction is the antecedent variable of customer loyalty in the Internet Shopping Mall. In addition, a significant impact of logistics service quality on relationship orientation of the customer is revealed. Implications of these findings are discussed, and limitations of the study as well as further research directions are addressed.

This study investigated causal relationships between goal orientation, sales and performance towards increasing the effectiveness of up-selling in internal promotion methods in family restaurants and provided implications about the hiring and training of sales people. The subjects were 232 sales people in family restaurants. The data were collected by self-administered questionnaires and analyzed by exploratory factor analysis, reliability analysis, comparative analysis of the average, and regression analysis. Results, showed that variations in goal orientation, sales, and performance depended on the age and experience of salespeople and that goal orientation makes adaptive selling more effective. It turned out that effort selling affects up-selling result than adaptive selling. Long-term workers were better than short-term workers in goal orientation, selling, and up-selling results, so human resource management needs to implement a long-term plan to enhance these effects. And, because effort selling is more effective than adaptive selling in up-selling results in family restaurants, effort selling requires training.

Cognitive Radio rules provide that the user outside service region should not utilize communication system in Cognitive Radio environment. The reason why main user should use service without any loss and interference. If this rule is guaranteed, CR users are able to be offered enough services outside service region. In this paper, we target the issue which can operate practical cognitive systems even without causing excessive interference to legacy users. Also, we focus use on non-interference to the primary system rather than realizable benefits for the secondary systems, and using the proposed device. In this paper, we present the possible scheme using Bi-directional Beamforming Antenna.
