The purpose of this study is to analyze the relationship of housewives’sense of ancestral service and behavior and to verify the how housewives’value orientation affects the sense of ancestral service and behavior. The data are collected from 393 housewives in urban. The statistics used for the analysis are Cronbach’$\alpha$, Frequency, Percentage, Mean, SD, and Multiple Regression Analysis. The results are summarized below: First, among the variables, degree of fate-control orientation is the most, on the contrary, material orientation is the lowest. Second, value orientation variables that affect sense and behavior of ancestral service are material orientation and gender equilibrium orientation. Third, the behavior of ancestral service is more traditional than sense of ancestral service. Fourth, cause-and-effect variable which affect behavior of ancestral service are education level, religion(Buddhism, Catholicism), employment status, number of children, health, daughter in -law’s ranking, sense of ancestral service, and value orientation, which affect the direct or direct and indirectly. Especially sense of ancestral service variable is the most important mediation one. We expect further studies on the sense of ancestral service and behavior with precise scale and sampling.

In this paper, we have presented the improved IF transceiver architecture and the implementation and experimental results on re-configurable transceiver based on digital IF for multiple wideband OFDM/TDD base stations for high-speed portable internet-service in which is issued Korea. The implemented IF transceiver has been designed to support multiple frequency allocations and multiple standards by only modifying the programmable software not its hardware like as the software-defined-radio concept. Also, the digital complex quadrature modulation technique has been used for the digital IF transmitter, which is able to combine multiple frequency bands in digital processing block not RF block and to reject the image frequency signals. And the bandpass sampling technique has been used for the digital IF receiver to reduce the sampling rate of ADC. This paper has shown the experiment results on the frequency response and constellation on the base-station implemented using the modified IEEE 802.16a/e physical layer channel structure based on OFDM/TDD.

Environmental issues and the need to reduce energy consumption for lowering operating costs have pushed power efficiency to become one of the major issues of current research in the field of wireless networks. This paper addresses a number of multiple input multiple output (MIMO) precoding and scheduling techniques across the PHY and MAC layers that can operate under a reduced link budget and collectively improve the transmit power efficiency of a base station, while maintaining the same levels of service. Different MIMO transmission and precoding schemes proposed for LTE, achieving varying degrees of multiuser diversity in both the time, frequency as well as the space domain, are examined. Several fairness-aware resource allocation algorithms are applied to the considered MIMO schemes and a detailed analysis of the tradeoffs between power efficiency and quality of service is presented. This paper explicitly examines the performance of a system serving real-time, VoIP traffic under different traffic loading conditions and transmit power levels. It is demonstrated that by use of efficient scheduling and resource allocation techniques significant savings in terms of consumed energy can be achieved, without compromising QoS.

The purpose of this study is to investigate 1) the level of the city housewives' sense and behavior of wedding and ancestral service according to the background variables, 2) the relationship of the sense of wedding and ancestral service and behavior, and 3) what the most influential factors are. For the purpose of this study, 700 questionnaire were distributed to the housewives who live in Seoul and collected during the February 1989. And the measuring instruments are composed of 9 questions, 11 questions of the sense of wedding service, 12 questions of the sense of ancestral service, 11 questions of the behavior of wedding service, and 12 questions of the behavior of ancestral service. To obtain the sense and behavior of wedding and ancestral service scale, item analysis through Pearon's correlation and factor analysis, frequency distribution, percentile, mean, standard deviation, t-test, F-test, Pearson's γ, Paired-t-test, Duncan's Multiple Range Test, and Stepwise multiple Regression were used for data analysis. The major fidnigs are as follows: 1. The general tendency of the city housewives' sense of wedding service was modern. That of the city housewives' sense of ancestral service was the mid level of the traditional and the modern. According to background variable (ie: age, educational level, the number of children, the duration of marriage, religion, the existence of job, the existence of married son and daughter), the city housewives' sense of wedding service is different significantly. Accoring to background variable(ie: age, educational level, the average home income a month, the number of children, the duration of marriage, religion, the existence of married son and daughter), the city housewives' sense of ancestral service is different significantly. 2. The general tendency of the city housewives' behavior of wedding service was modern. That of the city housewives' behavior of ancestral service was somewhat modern. According to background variable(ie: age, educational level, the number of children, the duration of marriage, the existence of married son and daughter, the form of family), the city housewives' behavior of wedding service is different significantly. According to background variable(ie" age, educational level, the number of children, the duration of marriage, religion, the existence of job, the existence of married son and daughter), the city housewives' behavior of ancestral service is different significantly. 3. There were positive correlation between the city housewive' sense and behavior of wedding and ancestral service(P<.001). And the housewives' sense of wedding service was modernized than that of ancestral service, the housewives' behavior of ancestral service was modernized than that of wedding service. 4. The city housewives' sense of wedding service was the duration of marriage(β=-.226), influential factor. And influential factors on that of ancestral service were educational level(β=.250), the existence of married son and daughter(β=-.123), number of children(β=-.101). The influential factors on the city housewives' behavior of wedding service were age(β=-.193), the form of family(β=.097). And that of ancestral service were educational level(β=165), the number of children(β=-.157).

The Thoroughbred horse was an approximately 4-years-old castrated male with highly emaciation, nasal epistaxis and subsequently died. Gross necropsy revealed epistaxis and hyperemia on the lung, multiple hemorrhage in muscle, and liver was focally attached to the peritoneum with fibrin. According to polymerase chain reaction (PCR), Equine herpes virus type 1 and 4 (EHV type 1, 4) was detected in the lung and trachea. In bacterial culture from kidney, liver, spleen, muscle and blood, Streptococcus equi subsp. zooepidemicus was isolated. Based on the gross lesion and PCR, this horse was diagnosed as EHV type 1, 4 and S. zooepidemicus coinfection.

Purpose: The purpose of this study is to measure the effectiveness of corporate social responsibility and service on consumers' risk perception, which ultimately influences satisfaction. Research design, data, and methodology: This study adopted experimental scenario questionnaires: 2 CSR conditions (with and without CSR) and 2 service outcomes (successful and unsuccessful). Multiple regressions were conducted to examine hypotheses. A total of 217 responses were gathered for research analysis. Results: The results of this study found that the performance risk perception and satisfaction of consumers were affected by both CSR and service. CSR was not found, however, to have a moderating effect on performance risk perception or satisfaction. Additionally, performance risk perception affected consumer satisfaction. Conclusion: The results of this study indicate that consumers respond to the conditions of company's CSR and service outcomes when they stay at hotels. Findings of this study suggest service outcomes and CSR had an effect on performance risk perception and satisfaction, although CSR did not moderate the effect of service outcomes for both performance risk perception or satisfaction. Therefore, providing satisfactory customer service and undertaking CSR activities are critical to achieving consumers' overall satisfaction.

This study suggested a theoretical research system on the effects of corporate social responsibility in the foodservice industry upon perceived service quality. Self-administered questionnaires were completed by 509 customers and the data were analysed by frequency, factor analysis, reliability analysis, correlation analysis and multiple regression analysis. The primary results are as follows - Three corporate social responsibility (CSR) factors were obtained - economic responsibility, legal.ethical responsibility and philanthropic responsibility. In addition, five factors were obtained from the factor analysis of perceived service quality - tangibility, reliability, responsiveness, assurance and empathy. Correlation analysis showed a significant correlation between the CSR factors and the customers' perceived service quality factors. Multiple regression analysis, to verify the hypothesis, showed that CSR in the foodservice industry had a significant influence upon customers' perceived service quality; therefore, the research hypothesis was adopted. CSR, which had an effect on tangibility out of the minutely-perceived service quality factors, was indicated in the order of economic responsibility, legal ethical responsibility and philanthropic responsibility. Responsiveness, reliability, and assurance were influenced by legal ethical responsibility, economic responsibility and philanthropic responsibility, respectively, in order. Also, empathy was surveyed to be influenced by legal ethical responsibility, philanthropic responsibility and economic responsibility in order. Consequently, customers' evaluations of perceived service quality may be inferred to have positive effects when the customer recognizes whether the foodservice company performs social responsibility.

This study was conducted to investigate the effect of relationship and service marketing on the brand interest and behaviors among Korean and Chinese active senior consumers and whether this effect differed between the two groups. A survey was conducted by having participants complete questionnaires administered by a research firm. For empirical analysis, frequency, EFA, CFA, SEM, the metric invariance test, and multiple-group comparison analysis were performed. The analysis results revealed that relationship marketing positively affected both brand interest and consumer behavior. Although service marketing positively affected brand interest, it did not have a significant effect on consumer behavior. In other words, brand interest positively affected consumer behavior through relationship and service marketing. Multiple-group comparison analysis demonstrated that no difference existed between Korean and Chinese active consumers in terms of how relationship marketing affected their brand interest, but a difference existed in how it affected their behavior. Service marketing had a greater influence on Chinese active senior consumers' brand interest than on Korean active senior consumers. However no difference existed between the two groups with respect to how service marketing affected their behaviors. Finally, brand interest had a positive effect only on Korean active senior consumers' behavior through relationship and service marketing, but not on Chinese active senior consumers. In conclusion, relationship and service marketing should be used to enhance the brand interest among Korean active senior consumers, and business activities should be planned by building relationships with Chinese active senior consumers to affect their behavior.

The main premise of this study is that family involvement which is based on professional-family collaborative partnership is very important for successful treatment and rehabilitation of the mentally ill. Accordingly, this study aims to find out factors which are related to family involvement in therapeutic process. This study conducted the survey with 275 service providers(i.e. mental health professionals) and with 124 service consumers(i.e. family members) in order to discover in what extent do related factors affect on the family involvement. The major findings of the study are; 1) From the service providers standpoint, using multiple regression, job characteristics, perception of family culpability, frequency of contact with family, functioning of their organization affect significantly on the family involvement by 33.0% of explanatory power. Using a step-wise multiple regression, the most powerful influenced factors on family involvement are frequency of contact with family, type of agency, type of profession, and their career. 2) From the service consumers standpoint, using multiple regression, socioeconomic level, attitudes of professionals, optimistic perception of prognosis, functioning of their family, diagnosis affect significantly on the family involvement by 40.9% of explanatory power. Using a step-wise multiple regression, the most powerful influenced factors on family involvement are economic level, attitudes of professionals, optimistic perception of prognosis, educational level. In conclusion, family accessibility to the therapeutic system must be allowed and further, politically encouraged by the related legislation. Also this study recommends clinician to use an empowerment model for the families with the mentally ill.
