Dongwon Systems established in 1977 to exclusively supply Dongwon tuna cans, the parent company. Instead of its stable management and profits by relying on the parent company, the company was not complacent and started innovating and challenging new markets. Dongwon Systems decided to expand the business area and pioneer new markets so that it becomes the first domestic company to successfully expand into independent businesses other than parent company products. Such success of Dongwon Systems was driven by its differentiated B2B strategies. Unlike the characteristics of usual B2B companies, Dongwon Systems has been thinking both of its client companies and end-consumers. In this case-study, we will explore how Dongwon Systems became the No.1 packaging solution company in Korea through technology innovation in the aspects of unique B2B marketing strategy. The key success factor can be summarized in three ways; product and technology development with customer centric mind-set, systematically extending new markets through business diversification, and marking Southeast Asia as a bridgehead for its global strategy. It is expected that the current case study of Dongwon Systems will be able to provide implications for B2C companies as well as B2B companies that try to expand their business portfolio and global business areas through B2B marketing case analysis.

The purpose of this study is to ascertain whether the effect of introduction of OCS(Order Communication System) to the hospital is satisfied or not comparing the anticipated effect with the actual effect. For this purpose, a domestic hospital which has introduced and has been operating OCS for several years was chosen. Based on the internal data of S Hospital prepared before introducing OCS, researcher has analyzed the basic direction, design standard and status of operation after the introduction of OCS, etc. After analyzing the status of operations of several departments using OCS and interviewing with the chiefs of pertinent departments, a survey form was designed. Actual survey and interviews were conducted by the researcher for weeks to know whether doctors, nurses, medical technicians and clerks of the patient management dept. were satisfied with OCS and to find if they have any recommendations to improve OCS. Based on the analysis of survey, the effect of OCS was evaluated whether it has satisfied the anticipated effectiveness. For the question if they feel convenient in using OCS, doctors, nursing staffs in charge of ward and the staffs of billing dept. has answered that they were all satisfied(100%). The answers for the same question were relatively high in the case of nurses in charge of outpatient and staffs of radiography. Of course, there have been some nurses and staffs who complained for the inconvenience. However, overall satisfaction was high on the average. Some common problems occurred after the introduction of OCS were frequent errors due to instability of OCS system, paralysis of function of hardware on data back-up system and redundant investment due to erroneous choice of DB program in setting DB. It was also pointed out that lack of computer education and low participation of medical staffs has resulted in failure of developing effective software. As a result, it has lowered the efficiency of OCS. For example, some works have to be done by hands even after OCS. Based on the result of this research, recommendations to maximize the effect of OCS were presented as follows. First, strong leadership of CEO and active cooperation of doctors are mandatory. Second, all the process of hospital work should be analyzed and be redesigned in more efficient ways. Third, OCS should be designed to be user-based system which can be used efficiently by all staffs of the hospital. Forth, prior to the operation of OCS, proper tests of the program and trainings of the pertinent staff are required. Fifth, prior to the selection of hardware, BMT(Bench Marking Test) should be conducted. Sixth, before introducing OCS, staffs in charge of OCS should visit many hospitals operating the OCS system and take their cases into account.

China is marking 9.4% annual growth rate in average since 1978. GDP reached $1090 in 2003 as the first time and China ranked at 4th with their economy size in 2006. One of the remarkable change in China is the extension of foreign open-door policy. China joined WTO in the end of 2001 and it strengthen the foundation of Chinese market economy structure and encouraged the inflow of foreign capital. While 400 of the 500 global corporations advanced into China, the economy trade has been rapidly increasing between Korea and China. The economy trade in both countries has been regularized since 1992 and the annual trade is tending upwards in last 15 years. Korean trade toward China reached 134,400 million which is increased 27 times compared with the total of 1982. In this period, Korean trade toward China marked 24.5% in Export increasing rate and 16.7% in import increasing rate. China became the 2nd biggest export country of Korea in 2001 and became the top in 2003. As the China foreign direct investment has been increasing rapidly, the number of Korean companies advanced into China has been remarkably increasing. By focusing on a thorough review of the nationally published documents of Korean-Chinese business management research during more than two decades (1981-2004), the present paper has been systematically classified and analyzed the current status of Korean-Chinese business management research. The paper raised some important issues regarding Korean-Chinese business management research and predominantly, its future prospects are outlined. In the paper, the documents which are registered in the Korean Academic Processing Foundation registration of journals and candidate registration of journals have been classified by: research purpose, main subject, research method and the results. Careful analysis among the research clarified the active and inactive business management research fields. This clarification enables us to get a better understanding of the current research of Korean-Chinese business management, and more importantly, it pointed out to the direction of future development of research. In addition, the systematic classification made by this paper may contribute to the decision making of subject index of Korean-Chinese business management research since there has been no classification standard of it until now.

Objectives : In this study, the dental treatment satisfaction degree of the patients, who experienced the sleep dental treatment or non-sleep dental treatment, the revisit rate and the differences among the encouraging intention were compared and analyzed, and the primary factors through which the satisfaction degree of sleep dental treatment has influence on the revisits and the encouraging intention were analyzed, and the proposal was made on clinic management to raise qualitative medical service level on the basis of this study. Methods : The questionnaires filled out by the 202 users of a certain dental clinic located in Pohang-si, Gyeongbuk were analyzed. The frequency analysis and the crosstabulation analysis of the general characteristics of survey participants were carried out, and the satisfaction difference between the sleep dental treatment and the non-sleep dental treatment was identified with the t-test analysis. The multiple regression analysis were carried out to identify the factors through which the sleep dental treatment has influence on the through which the satisfaction degree of sleep dental treatment has influence on the satisfaction degree of the medical service and the revisited dentists. Results : In the medical service satisfaction degree in general, the sleep dental treatment had the higher meaningful value than the non-sleep dental treatment(p<0.05). In the case of the difference in satisfaction degree on each medical service factor, the satisfaction of the sleep treatment group was high in every case, but the meaningful difference showed up in the factors of waiting time, treatment procedure, revisit and the encouraging intention(p<0.01). The revisit to the sleep treatment dental clinic and the recommending dentist increased in proportion to the satisfaction degree of sleep dental treatment, and the Beta value appeared to be 0.337 at the influence of the subordinate variable(p<0.001). As for the influence on the sleep dental treatment satisfaction, the Beta value of the dental hygienist was the highest, marking the value at 0.375(p<0.01). As for the satisfaction of the patients who experienced the sleep dental treatment, the Beta value of the treatment fee was the highest, marking 0.352(p<0.001), in the multiple regression analysis of the revisit and the encouraging intention, and the 0.156 of dentist factor and the 0.152 of treatment procedure and waiting time showed lower regression coefficient(p<0.05). Conclusions : It is assumed that the satisfaction degree of sleep dental treatment, which is carried out as a new dental service has influence on the increase of revisit to the dental clinic as an important factor. But it was disclosed that the high level of treatment fee has the biggest influence on choice of revisit to the dental clinic. In the current medical charge system, the sleep dental treatment appeared to have a big influence on raising the quality of dentists, the satisfaction of patients, the revisit and encouraging intention, and also the roles of the dental hygienist was important. It is assumed that these facts are functioning as the factors that are linked to the increase of revisit and the encouraging intention.

AQM은 라우터에서 사용되고 있으며 큐의 순간적 길이나 평균길이를 관찰하여 혼잡을 예측하고 탐지하는 알고리즘이며, 평균 큐길이가 임계 값을 초과하면 혼잡이 발생하였다고 추론하고 라우터로 유입되는 패킷을 미리 폐기시키거나 패킷 전송 노드에게 혼잡을 미리 알림으로써 전송노드에서 전송률을 줄여 혼잡을 피하도록 한다. AQM 알고리즘의 하나인 RED (random early detection)는 패킷을 무작위로 폐기시켜 혼잡제어를 하는 큐 기반의 혼잡 제어기술이다. RED는 TCP의 시간경과 및 큐 지연을 줄이며 링크 활용도를 높이고 버스트한 트래픽이 유입되는 것을 관리하는 기술로써 널리 사용되어지고 있으며 혼잡도의 정도를 큐의 평균 길이로 추정한다. 그러나 파라미터($P_{max}$, $TH_{min}$)값들이 고정되어 있어서 특정한 네트워크 환경에서는 동작을 잘 못한다. 본 논문에서는 네트워크 상태를 지속적으로 감지함으로써 $P_{max}$와 $TH_{min}$의 값을 네트워크 상태에 적합한 값으로 자동적으로 바꾸어줌으로서 다양한 환경에서도 동작을 잘할 수 있는 확장 RED를 제안한다.

국내 건설경기는 주택경기 침체, 글로벌 금융위기 등의 영향으로 2008년부터 본격적인 침체가 최근까지도 지속되고 있으며, 장기화되고 있다. 이러한 어려움을 타파하기 위해 건설기업에서도 서비스기업과 같이 내부마케팅 활동을 강화시켜야 한다. 하지만 건설기업은 기존의 서비스기업과 달리 직접적으로 고객을 응대하지 않을 뿐 아니라 건설 현장이라는 특수한 상황에 처해 있어 적극적 내부마케팅 활동 강화가 쉽지 않은 상황이다. 따라서 내부마케팅 활동 중 우선순위를 선정하여 가장 시급한 부분부터 개선해 나아가야 한다. AHP 분석 결과 1계층에서 내부 의사소통이 가장 우선적으로 강화시켜야 할 요소로 나타났으며 그, 다음으로 근무조건 및 환경으로 나타났다. 그 다음 각각의 상위 개념별 하위 활동을 보면 내부 의사소통에서 상사와의 의사소통을, 근무조건에서는 일일 근무시간 전반적 만족을, 보상 및 포상에서는 수주 기여 시 보상으로 나타났다. 교육훈련에서는 전문가들의 의견 일치를 보지 못하였다.

전송계층 프로토콜처럼 전송제어 프로토콜은 안정적인 데이터 전송 서비스를 제공한다. 다양한 네트워크에서 TCP의 성능을 저해하는 일부 심각한 문제가 있다. TCP 네트워크 환경에서 중요한 문제는 빠른 전송 속도로 인해 또는 동시에 네트워크로 접속하는 다수의 새로운 접속으로 인하여 발생하는 혼잡이다. 그러므로 라우터에서 큐의 크기는 패킷 하락에 기인하여 증가한다. 손실된 패킷의 재전송과 감소된 처리량은 많은 비용을 발생시킨다. RED처럼 AQM과 ECN은 패킷 하락 보다는 패킷 마킹에 사용된다. IP 패킷 헤더에서 ECN 비트는 불필요한 패킷 하락을 피하기 위한 혼잡 표시로 추가할 수 있다. 제안하는 ECN과 AQM 메커니즘은 NS2 시뮬레이터의 도움으로 구현할 수 있으며, 그 성능은 다른 TCP 변종에서 테스트할 수 있다.

Education on the physician continues with undergraduate medical education, graduate medical education, and continuous medical education. The countries such as the United States, Japan, the United Kingdom, German, and others are required to undergo training in the clinical field for 2 years after completing the national medical examination, and to become doctors after passing the clinical practice license test. Korea can obtain a medical license and become a clinical doctor at the same time if it passes written and practical tests after completing 6 years of undergraduate medical education or 4 years of graduate school. About 90% of medical school graduates replace clinical practice with 4-5 years of training to acquire professional qualifications, but this is an option for individual doctors rather than an extension of the licensing system under law. The medical professional qualification system is implemented by the Ministry of Health and Welfare on the regulation. In fact, under the supervision of the government, the Korean Hospital Association, the Korean Medical Association, and the Korean Academy of Medical Sciences progress most procedures. After training and becoming a specialist, the only thing that is given to a specialist is the right to mark him or her as a specialist in marking a medical institution and advertising. The government's guidelines for professional training are too restrictive, such as the recruitment method of residents, annual training courses of residents, dispatch rule of the residents, and the quota of residents of training hospitals. Although professional training systems are operated in the United States, the United Kingdom, France, and Germany, most of them are organized and operated by public professional organizations and widely recognize the autonomy of academic institutions and hospitals. Korea should also introduce a compulsory education system after graduating from medical education and organize and initiate by autonomic public professional organization that meets global standards.
