This study analyzed the fishery and maritime vocational high school teachers' recognition on the outcomes and future agenda. In addition, it delineates the importance of the vocational education division being carried out for 10 years in the College Scholastic Achievement Test (CSAT). In order to gather relevant information, 76 teachers who work in 12 different fishery and shipping vocational high schools around the country were surveyed. The findings of the fishery and maritime department teachers' recognition on the matter are as follows: First, the biggest impact the vocational education division in the CSAT had was on the promotion of continuing education and on the fulfillment on the vocational high school students' desire to compete and enter universities. Second, the CSAT with the vocational education division allowed students to choose a variety of paths after high school whether they be full-time employments or pursuing a degree in universities. Third, the biggest obstacle for the vocational education division in the CSAT is in the most metropolitan universities not honoring the CSAT scores as a criterion in the admission process.

Background: Clinical indicators are objective measures of process or outcome of patient care in quantitative terms. This study aims to review the medical records of patients who 'return to operating room during the same admission', which is one of the critical clinical outcomes, and describe the result by unplanned reoperation rate. Methods: Computerized patient registry was used for selecting subject conditions. For medical records retrieved, two nurse evaluators identified the presence of explicit reoperation planning in medical records. Results: Overall reoperation rate was 2.8% and unplanned reoperation rate 1.3%. The main category of reoperation cause was the postoperative bleeding. Duration of stay from previous operation to reoperation of the unplanned group, 12.7 days, was shorter than that of the planned(p< .05). The differences did not reach statistical significance in age, sex and length of stay. Conclusion: Results suggested that unplanned reoperation rate was lower than 'threshold' level other institutions had established. However, this result could become comparable only after management of medical records would be improved and risk adjusted.

In the Internet, an identity service must to obtain permission from a user to allow them to share data with requesting service. For that, the privacy policy, which reflects legal regulations and preferences made by the user, is needed. Also, the management interface that aids the user to make the privacy policy and the PDP system that makes admission control and policy decisions in response to a request from an entity wanting to access the personal information are needed. In this paper, the privacy controller system model handled under the internet Identity management system environment is proposed. The system has the easy interface of policy generation and the efficient policy decision process. The system applies and modifies to the XACML of OASIS group. We propose that the privacy policy is divided into the three policies, which are the user policy, the domain policy and the basic offering policy. To resolve the collision between the policies, we also propose the collision resolution policy.

1. Objectives: This case study described a process of the patient diagnosed as acute hepatitis A treated by medication based on the Sasang Constitutional Medicine and acupuctural theraphy and obtained improved effects about several symptoms. 2. Methods: We diagnosed the male patient with acute hepatitis A as Tae-Eumin Exterior-Cold-Disease by the Cold in the Esophagus, and administered Mahwangbalpyo-tang and Handayeolso-tang according to clinical progress. And we evaluated the results by liver function test(LFT; AST, ALT, $\gamma$-GTP ), total bilirubin level and the visual analog scale(VAS) of symptoms. 3. Results and Conclusion: Almost symptoms (except for jaundice) at the time of admission were disappeared, and also jaundice (estimated by color of scleras and color of urine) was alleviated. Also level of AST, ALT, $\gamma$-GTP and total bilirubin decreased in laboratory test. We obtained positive effects to the therapy but we considered necessities of further comparative studies with control group.

Purpose: This descriptive research was conducted to identify educational needs in pediatric nursing handoff training to improve students' handoff skills. Methods: Data were collected using a survey with 188 senior nursing students and 48 pediatric nursing professors and clinical nurses. The survey included items on general information as well as experiences in handoff training, necessity, training content, and items for a handoff training program in pediatric nursing. Results: Of the nursing students, 30.5% reported receiving handoff training during their clinical hours. After their handoff training, the students' confidence index was only 3.78 out of 10. Significantly, 98.3% of the respondents said that pediatric handoff training is necessary. In addition, participants reported that simulation practice (26.5%) is an appropriate educational method, and the time required for handoff training should be 8.16 hrs. Admission process was placed first as the most critical circumstance for handoff (56.8%). High demands were observed for the necessity of training content for patients with respiratory problems. Conclusion: The results of this study show the various educational needs for developing a patient safety pediatric handoff training program to promote nursing students' skills in handoff.

In ATM networks there are two methods in traffic control as schemes advancing the quality of service. One is reactive control after congestion and the other which is generally recommended, is preventive control before congestion, including connection admission control on call leel and usage parameter control, network parameter control, priority control and congestion control on cell level. In particular, usage parameter control is required for restricting the peak cell rate of bursy tracffic to the parameter negotiated at call set-up phase since the peak cell rate significantly influences the network quality of service. The scheme for progressing quality of service by usage parameter control is themethod using VSA(Virtual Scheduling Algorlithm) recommended ITU-T. The method using VSSA(Virtual Scheduling Suggested Algorlithm) in this paper is suggested by considering cell delay variation and token rate of leaky bucket, compared VSA and VSANT(Virtual Scheduling Algolithm with No Tolerance) with VSSA which polices violated cell probability of conformed peak cell rate and intentionally excessive peak cell rate. VSSA method using IPP(Interruped Poisson Process) model of input traffic source showed more quality of service than VSA and VSANT methods as usage parameter control because the suggested method reduced the violated cell probability of contformed peak cell rate and intentionally excessive peak cell rate.

Two asymptotic analyses of the queue length distribution at a statistical multiplexor supporting heterogeneous exponential on-off sources are considered. The first analysis is performed by approximating the cell generation rates as a multi-dimensional Ornstein-Uhlenbeck process and then applying the Benes queueing formula. In the second analysis, w state with a system of linear equations derived from the exact expressions of the dominant eigenvalue of the matrix governing the queue length distribution. Assuming that there are a large number of sources, we obtain asymptotic approximations to the dominant eigenvalue. Based on the analyses, we define a traffic descriptor to include the mean and the variance of the cell generation rate and a burstiness measure. A simple expression for the quality of service (QoS) in cell loss rate is derived in terms of the traffic descriptor parameters and the multiplexor parameters (output link capacity and buffer size). The result is then used to quantify the factors determining the required capacity of a call taking the statistical multiplexing gain into consideration. As an application of the analyses, we can use the required capacity calculation for simple yet effective connection admission control(CAC) algorithms.

Purpose: Purposes of this study were to identify non-value-added nursing activities (NVANAs) and to estimate the amount of time spent on NVANAs among total nursing activities. Methods: Non-value-added nursing activities were identified though the use of a focus group. The nurses in the focus group were nurses working in a tertiary hospital. They discussed possible activities that could be NVANAs. Based on the focus group discussion, a pilot study was done to examine the actual occurrence of NVANAs in clinical settings. Results: The focus group discussion showed that NVANAs occurred in ten categories of nursing performances including communication with physicians, communication with other departments, medications, equipment/supplies, nursing records, tests, admission, discharge, and transfer. Direct nursing activities accounted for 35.5% of total nursing activities while indirect nursing activities accounted for 64.5%. Of indirect nursing activities, 16% were NVANAs. Most NVANAs were related to communication and equipment/supplies. Conclusions: To improve the quality and efficiency of nursing activities, it is necessary to identify NVANAs and their causes. Results of this study suggest that improvement in the work process and nursing unit structure, support for equipment/supplies, and effective communication are needed to reduce NVANAs in tertiary hospitals in Korea.

The wireless communication network is evolving toward IMT-2000 for providing various multimedia services. In order to accomplish this ultimate goal the effective schemes are required which can dynamically utilize the limited wireless resources based on different traffic characteristics of various services. This paper proposes a novel bandwidth allocation and call admission control scheme to transmit multimedia traffic based on the bandwidth reservation procedure using direction estimation in the IMT-2000 This scheme estimates the position of mobiles based on the mliticriteria decision making in which uncertain parameters such as RSS(Received Signal Strength), the distance between mobile and base station the moving direction and the previous location are participated in the decision process using aggregation function in fuzzy set theory. Its effectiveness is investigated by simulation.

The purpose of this study was to propose for efficient selection with observation and nomination system and efficient operation of Convergence Science class in a Science Institute for Gifted Youth attached in university. For this purpose, we analyzed the result of entrance exam with observation and nomination system, and the correlation between enterance exam score and achievement to perform at the Convergence Science class. As a result, despite observation and nomination system is highly dependent on observers and recommenders, they have very different perspectives each other. In addition it was founded that selection and education process after admission is inconsistent.
