Purpose: Importance of patient satisfaction related to patient-centeredness has been emphasized, and it is known to have effect on various health outcomes including health resource utilization. However, the effect of patient satisfaction has been discussed mostly in terms of hospital marketing in Korea. This study aims to examine the effect of patient satisfaction in patient-physician communication on healthcare utilization in a nationally representative adult population of South Korea. Method: Patient satisfaction with physician communication is assessed using 4 items in the 2011 Korea Health Panel Survey. Generalized linear regression analysis is conducted using 9,325 adults' healthcare utilization in 2012. Findings: Adjusting for the socio-demographic, economic factors, individual health status, health behaviors and healthcare utilization in 2011, more satisfied individuals, more likely to utilize the outpatient service, especially in clinical setting. Practical Implications: The study findings suggests that in context of South Korea healthcare system such as insufficient medical consultation time and the absence of health delivery system, patient satisfaction as a subjective healthcare quality indicator would have effect on the individual's outpatient visit. This study contributes to stimulate patient satisfaction research and discussion in South Korea to further explore its relationship with potential and various health related outcomes. Further implications of the study are discussed.

개인 통신 서비스(PCS)는 미래의 고도 정보화 시대에서 정보 전달의 중요성에 대한 요구를 충족시키기 위한 총체적인 개인 정보 전달 서비스이다. 기폰의 통신 전달 매체를 기본으로 한 통신 방법에서 개인의 이동성을 보장하는 개인 통신 서비스의 구현을 위해서는 상당한 지능을 갖춘 지능망의 사용이 필연적이며, 이러한 정보를 처리하기 위해서는 고속 대용량의 데이타 베이스 시스템의 개발이 중요한 과제이다. 연역 데이타 베이스는 데이타의 일반적인 법칙을 연역 법칙으로 표현할 수 있으므로 지능망의 데이타 관리에 적절한 시스템으로 고려된다. 지능망 데이타 베이스는 신속한 통신 전달을 위해 빠른 시간안에 주어친 절의의 처리가 가능해야 하므로, 이논문에서는 앞으로 보편적으로 사용될 병렬 시스템 에서 연역 데이타 베이스를 주기억 장치 데이타 베이스 시스템으로 구현하는 방안을 제시한다.

For the compression of color images, a common bitmap usually is generated to replace the three individual bitmaps that originate from block truncation coding (BTC) of the R, G and B channels. However, common bitmaps generated by some traditional schemes are not the best possible because they do not consider the minimized distortion of the entire color image. In this paper, we propose a near-optimized common bitmap scheme for BTC using Binary Ant Colony Optimization (BACO), producing a BACO-BTC scheme. First, the color image is compressed by the BTC algorithm to get three individual bitmaps, and three pairs of quantization values for the R, G, and B channels. Second, a near-optimized common bitmap is generated with minimized distortion of the entire color image based on the idea of BACO. Finally, the color image is reconstructed easily by the corresponding quantization values according to the common bitmap. The experimental results confirmed that reconstructed image of the proposed scheme has better visual quality and less computational complexity than the referenced schemes.

Recently, Communication media have been developed for the underwater communication in underwater environments where the underwater communication failures occur frequently. Although the underwater communication by one medium is not stable due to the influence of the underwater environment, the use of various communication media can complement each other and so this makes the underwater communication more stable. For this reason, this paper proposes approaches to the design and implementation of integrated MAC for complementing individual unstable underwater communications. In addition this paper presents the comparison and analysis on each of the proposed approaches so to be able to provide guidelines to designers and implementers of integrated MAC.

Objectives: The objective of this study is to present the basic data required for effective communication by identifying the effects of communication within the hospital organization on organizational conflict and organizational performance. Methods: For this study 298 medical workers and general administrative staff working in small and medium hospitals were selected. Results: Upward and downward communication had a negative effect on individual conflict and on upward, and horizontal communication between individuals. Likewise, horizontal communication had a negative effect on conflict between groups. Upward, downward, and horizontal communication are defined based on organizational performance. It has been shown to affect. Conclusions: In order to improve conflict management and performance within hospital organizations, effective communication plans appropriate to the situation and targets have to be developed.

This Paper examines the effect of IT knowledge and IT communication on the operational performance of small firms. Small firms which could be defined firms with less than 50 people in total lags behind medium and large firms in computerization. In order to fill up the computerization gap resulted from size differences, Korean government has been promoting the 'Networking Small Firms' project since 2001. Survey data with 698 small firms in Korea, we could find that If knowledge and IT communication significantly contributed to the operational performance of small firms. Internal process performance is affected by individual IT knowledge, traditional communication, and e-mail communication. Customer performance is affected by above three factors, organizational IT knowledge and internet/EDI communication. Interestingly, financial performance is not affected by traditional communication but only IT knowledge and IT communication.

기업 뿐 아니라 사회의 개별 구성원에게 있어서도 컴퓨터 통신 기술의 활용이 급속히 확산됨에 따라 이러한 가상 공간상에서의 활동에 대한 관심이 높아지고 있다. 특히, 가상사회에서의 상거래를 다루는 전자상거래에 대한 연구는 기업과 기업간 전자상거래에 대한 연구를 넘어 기업과 고객간의 전자상거래에 대한 연구로 확대되고 있다 그러나 전자상거래를 이용하는 소비자에 대한 연구와 이해는 아직도 여러 가치 측면에서 매우 미흡한 실정에 있다. 실물 공간에서의 소비자에 대한 마케팅 분야에서의 연구가 새로운 거래 패러다임인 전자상거래에 대한 설명으로 확대될 수 있는 범위와 논리도 아직 충분하지 않으며, 소비자이며 동시에 기술 사용자라는 특성이 어떻게 통합될 수 있는지에 대한 연구도 미흡한 실정이다. 전자상거래를 추진하고 있는 사업자에게 있어서는 가상사회의 이용자에 대한 심도 있는 분석과 이해가 필수적인 요건이 될 것이다. 본 연구에서는 가상사회에서의 기술 이용자의 개인적인 심리적 특성이 매체와 기술의 이용패턴과 어떤 관련성을 가지고 있는지를 분석함으로써 가상사회 구성원의 행태적 특성을 파악해 보고자 하였다.

The purpose of this study was to show general trends in the psychological environment of family and problem behaviors perceived by adolescents and examine possible changes in such trends in accordance with the individual variables of adolescent, and then find out the effect of these variables on adolescents' problem behavior. The subject were 1374 adolescents of middle school in Busan(male 698, female 676). The main results were as follows : (1) General trends in the degree of parental monitoring showed that girls had more high than boys, and in the degree of family discord, boys showed more high than girls. In the degree of openness of parent-adolescent communication perceived by adolescents showed that girls had more open communication with mother than boys. Such trends in problem behaviors indicated that adolescents had the attention problem most. According to gender, girls had more problems in withdrawal, somatic complain, anxiety/depression, thought problems, attention problems, destructivity/identity, internalizing problems, total behavior problems in comparison to boys. Boys did delinquent behaviors more than girls. (2) For boys, the monthly income of their family, family discord, and the mother-adolescent communication have a significant direct effect on internalizing problems, externalizing problems and total behavior problems. Besides mother's employment and the type of family have a significant indirect effect on behavior problem. For girls, mother's employment, parental monitoring, family discord, and father-adolescent communication have a significant direct effect on internalizing problems. Mother's employment, family discord, mother-adolescent communication have a significant indirect effect on externalizing problems and total behavior problems. Bisides mother's employment, grade, the type of family, dating have a significant indirect effect on behavior problem. (3) The variables to have a significant influence on the parental monitoring showed as the monthly income of their family, dating, mother's employment, the type of family, the family discord showed as mother's employment on the parent-adolescent communication showed as the type of family. (4) Family discord was the most powerful predicator of problem behaviors of middle school students.
