Diverse multimedia services will be deployed at hand on 3G-and-beyond multi-service CDMA systems in order to satisfy different quality of service (QoS) according to traffic types. In order to use appropriate resources efficiently the call admission control (CAC) as a major resource control mechanism needs to be used to take care of efficient utilization of limited resources. In this paper, we propose a QoS-aware CAC (QCAC) that is enabled to provide service fairness and service differentiation in accordance with priority order and that applies the different thresholds in received power considering different QoS requirements such as different bit error rates (BER) when adopting total received power as the ceil load estimation. The proposed QCAC calculates the different thresholds of the different traffic types based on different required BER applies it for admission policy, and can get service fairness and differentiation in terms of call dropping probability as a main performance metric. The QCAC is aware of the QoS requirement per traffic type and allows admission discrimination according to traffic types in order to minimize the probability of QoS violation. Also the CAC needs to consider the resource allocation schemes such as complete sharing (CS), complete partitioning (CP), and priority sharing(PS) in order to provide fairness and service differentiation among traffic types. Among them, PS is closely related with the proposed QCAC having differently calculated threshold per each traffic type according to traffic priority orders.

The study conducted Comparative Analysis on the difference of College Scholastic Ability Data divided by type of admission process through the mileage program. Analysis result in following sequence. Leadership and relationships : CSAT(CSAT) > TOSR(subject), CSAT(CSAT+TOSR) is lower than each types ; mainly TOSR(total), TOSR(subject), CSAT(CSAT). Global : CSAT(CSAT+TOSR) & CSAT(CSAT) is higher than mainly TOSR(total) & TOSR(subject). Career and job search : TOSR(total) & TOSR(subject) is higher than mainly CSAT(CSAT+TOSR). Sum of mileage score : CSAT(CSAT) is higher than TOSR(subject) & CSAT(CSAT). Given this as a result, If you look simply at the activities of joint participation of leadership and relationships, student of mainly TOSR(total) admission do well college life with existing research. But with analysis results of K-Leader mileage this research shows that students of mainly CSAT(CSAT) admission do well college life. * CSAT(College Scholastic Ability Test), TOSR(a transcript of school records)

The aim of this study is to analyze the variations among hospitals and hospital groups in resource use and procedures of diagnostic and therapeutic process, such as laboratory tests, radiologic examinations, tissue diagnosis, timing of surgery after admission, the time required for operation. The study was performed for five procedures including cesarean section (C/S), appendectomy, cholecystectomy, cataract extraction, and pediatric pneumonia. The 2,316 subjects were selected from medical insurance claims list, and from this list 413 cases were sampled for medical record review. The patterns of resource utilization and process of treatment were described according to hospitals and characteristics of hospital groups. The major results were as follows : 1. The numbers of laboratory and radiologic tests showed significant difference among hospitals and hospital groups. In case of hospital groups, we could find tendencies of more tests with increasing hospital bed size. 2. In general, the proportion of operative cases evaluated by tissue diagnosis postoperatively among all operations ranged from 28.3% to 100%. The proportion varied among hospital groups, of which general hospital A group(more than 15 specialty) showed the highest proportion. 3. Post-admission delay until operation and the time required for operative procedure were not invariable among hospitals and hospital groups. The duration of operation in tertiary hospitals was slightly shorter than general hospitals, with varying statistical significance. We could find that probably there were differences of quality among hospitals in some components of procedures, which suggested that the implementation of quality assurance activities would be mandatory. In this study, we simply described the patterns of resource utilization and some features of clinical process, with institution of the need for advanced studies with in-depth analyses for each component of diagnosis and treatment procedures.

Objectives Low back pain (LBP) is one of the most common reason for people in Korea to visit Korean medical institutions. To assess actual amounts of use in the treatment of LBP in Korean medicine and to provide objective base line data for policy decision making, research regarding the current state of LBP patients' treatment in Korean medical institutions are in need. Methods The current study was designed as a retrospective chart review to investigate descriptive characteristics of LBP patients. The clinical records of 304 patients who were hospitalized for the treatment of LBP in Korean rehabilitation medicine inpatient clinics of five different Korean medicine hospitals were analyzed. The percentage of patient characteristics such as sex, age, average duration of admission, insurance type, diagnosed LBP related disease code, and rates of interventions applied were assessed. Results 1. The female sex was significantly predominant among patients with LBP : 105 patients (34.5%) were male and 199 patients (65.5%) were female. Percentage of the patients' age appeared as followed : 76 people (25.0%) were in their 50s, 64 people (21.1%) were in their 40s, 51 people (16.8%) were in their 30s, 37 people (12.2%) were in their 60s, and 33 people (10.9%) were in their 70s. Approximately half of the total LBP patients investigated were older than 50. 2. The average duration of admission was 16.2 days. Approximately one third (30.3%) of the patients were hospitalized for 8 to 14 days. 3. Female patients tended to stay admitted in hospitals slightly longer than male patients. Elderly (age 60~79) patients stayed in hospitals longer (17.8 days) compared to younger (age 20~39) patients (13.5 days). 4. More than half of the patients (171 cases, 56.3%) had their hospital bills covered with automobile insurance. 40.1% (122 cases) of the patients had medical insurance to cover their hospital bills. The average duration of admission of patients who had automobile insurance was 14.2 days, while that of the patients who had medical insurance was 18.4 days. 5. "Sprain and strain of the lumbar spine and pelvis" was the most commonly used (195 cases, 64.1%) disease code in patients with LBP. Patients diagnosed as "lumbar and other intervertebral disc disorders with radiculopathy" required the longest admission duration (22.1 days). 6. Herbal medication was applied to all of the patients during admission. Acupuncture was applied to all of the patients except one case diagnosed as spinal stenosis. Physical therapy, cupping therapy, moxibustion therapy, chuna therapy, and pharmacopuncture therapy were applied to 94.7, 92.8, 85.2, 83.9, and 49.7% of the patients, respectively. 7. There were certain differences among Korean medicine hospitals in terms of the LBP patients' duration of admission, type of insurance, frequency of the disease code use, type of intervention applied. Conclusions It is thought that the current study can be used as reference data in assessing the current state of LBP treatment in Korean rehabilitation medicine and a basis for future research. Provided improvements of certain limitations of the current study in future researches, such data would act as better base line data in policy decision making.

Congestion and memory occupancy in computer system may be reduced further if new jobs are admitted only when the num-ber of jobs queued at CPU is below CPU run queue cutoff (RQ). In this paper we prove that response time of a job is invariant with respect to RQ if jobs do not communicate each other. We also demonstrate this invariance property numerically using marix-geometric methods and present an approximate method for the delay due to context switch-ing under time slicing. The approximation suggests that time slicing with constant overhead yields a throughput similar to an FCFS system without overhead.

In this paper, we look at mediation of public policies in different areas of governance. Editorials appearing in an Indian English language newspaper during the period of an intense public debate on the issue of affirmative action in favor of a section of the population, the Other Backward Classes (OBC) - a popular reference to the socially and educationally backward classes of citizens under India's constitution constitute the sample for the study. Apart from editorials on the public policy of reservation of seats in admission to higher education institutions for the OBC, editorials on three other areas of governance, namely, development, economy, and public administration appearing in the same newspaper, are also consulted to understand media framing of social issues and more specifically, issues of social justice. Inductively identifying the various frames used in its editorials by the newspaper, I detect predominant use of 'personalized' frame in respect of editorials pertaining to the policy area of social justice; and distinguish it from the 'generic' frame of 'characterization' found in theory. The study concludes that the sample editorials in respect of other public policies did not use the personalized frame found in editorials on social justice.

As a number of new college students is gradually decreasing, each college is trying to find various solutions for gathering many students and operating a school. In specialty, information such as entrance examination and matriculation status data is very important for a college to decide a direction of admission and public relations policy, and increase welfare of the school. Therefore, it is seriously needed for a school to introduce a matriculation management system that can do the effective analysis through various entrance examination and matriculation status data and decision factors of school. In this study, I developed a matriculation management system which can analyze information of applicants, successful candidates and registrants based on national framework data. It is expected that the developed system can provide appropriate and rational information for public relations policy and operation to a college.

This study is to grasp a trend of profitability classified by characteristics of hospitals and to analyze related factors. Subjects are 145 hospitals which have gotten the standardization audit by Korean Hospital Association during 1998-200l. Profitability was measured in the aspect of operation profit rate with operating margin to gross revenue as proxy variables. Independent variables were classified by general factors (ownership, number of beds, period of establishment, competition), financial factors (liabilities to total assets, current ratio, fixed ratio, total asset turnover, inventories turnover), and factors related to patient treatment (average length of stay, bed occupancy rate, new outpatient ratio, admission ratio of outpatients, number of patients per specialist, personnel costs per adjusted inpatient, administrative costs per adjusted inpatient). Hierarchical multiple regression analysis model was used in this study. As a result of hierarchical multiple regression analyzation of operating margin to gross revenue, adjustive $R^2$ of general factors was relatively more powerful. The factors had significant effect on operating margin to gross revenue were ownership(+), number of beds(+), competition(+), current ratio(+), fixed ratio(+), total asset turnover(+), personnel costs per adjusted inpatient(-).

본 논문에서는 인터넷 QoS(Quality of Service)보장을 위하여 제안된 Diff-Serv(Differentiated Service)모델을 구현하고, QoS 를 보장하지 않는 BE(Best Effort)서비스와 우선 순위가 높은 패킷을 처리하여 QoS 를 보장하는 EF(Expedited Forwarding) 서비스의 차이를 통하여 Diff-Serv 망의 우수성을 입증하고자 한다. Diff-Serv 망은 BB(Bandwidth Broker)와 에지라우터 그리고 다수의 코어라우터로 구성된다. BB 로부터 라우터에 QoS Policy를 전송하기 위하여 COPS(Common Open Policy Service) 프로토콜을 구현하였으며, 사용자와 BB 사이의 SLAT/RAR(Service Level Agreement/Resource Allocation Request)를 처리하기 위하여 Admission Control 이라는 명명한 자체 프로토콜을 개발하였다. 구현된 Diff-Serv 망에서 QoS 보장 테스트를 위하여 19.2Mbps 대역폭이 요구되는 HDTV 스트리밍 서비스를 이용하여 인위적으로 Background Traffic 을 발생시켰을 때, BE 서비스만을 지원하는 망에서는 현저하게 서비스의 질이 떨어지는 반면에 Diff-Serv 망에서는 QoS가 보장됨을 알 수 있었다.

The purpose of this article was to evaluate the effects of reimbursement system on the basis of diagnosis-related groups(DRGs). We searched articles which was published from 1970 to 2000 using MEDLINE ； Key words "diagnosis-related groups, DRGs, prospective payment system, PPS. Then we reviewed 97 articles on classifying them into several categories of contents. It seems that the effects of DRGs in controlling hospitals cost in the U.S. was not clear cut. The U.S. Medicare PPS using DRGs remains vulnerable to compensatory increases in ambulatory care and long-term care facilities utilization despite cost per case and cost per admission being reduced. Also some research indicated the possibilities of deterioration in health care service quality. So putting theses results together, much more consideration is needed before the application of DRGs reimbursement system in Korea. Particularly there is the crucial difference between U.S. health care system and Korean, we must be aware of the limitations of DRGs and revise the DRG system to applicable in Korea.orea.
