In order to account for whether a doctor should indemnify damages resulted from violation of duty of care, the fact that a doctor violated duty of care, that damages were incurred, and the link between violation of duty of care and damages incurred, respectively, should be verified. So even though a doctor violated duty of care to patients, he or she will not bear the responsibility to indemnify damages unless it is not verified. If a doctor's negligence in medical practices is assessed that obviously unfaithful medical practice far exceeds the limit of admission of a patient, it will not go against people's general perception of justice or law and order to constitute a medical malpractice itself as an illegal action that will require liabiliy for damage. However, when the limit of admission is set too low, a patient's benefit and expectation of proper medical treatment can be violated. In contrast, if the limit of admission is set high, it can leave too little room for doctors' discretion for treatments due to a bigger risk of indemnification for damages. Thus, a reasonable balance that can satisfy both benefit and expectation of patients and doctors' right to treatment is needed.

Multiplex is a representative culture facility of citizens. Therefore, a lot of researches and investment on multiplex are carried out to improve benefits of service suppliers and users. Especially, focused on main services of a theatre such as ticket booking and issuing within multiplex, examination of tickets, admission information of movie screens and screening information inquiry, improvement activities are carried out. However, it is not enough to evaluate on what efficiency the above efforts have in the viewpoint of customer benefits and business. Therefore, this study analyzed value and limit of the newest service of multiplex applying the existing ubiquitous concept(u-multiplex service), and proposed a model and a plan for improving the existing services. The study interviewed with specialists in the related field and applied workshop-shape group interview to 110 university students and simulated service models. The contribution of the study is to analyze the value and limit of the existing multiplex service objectively, and to propose a new service model and plan to improve its limitation. In the future, the study plans to research on service models by extending space and functional roles of multiplex to the whole subsidiary facilities including movie screens.

In this paper we propose an analytical model for jitter, wherein we implement the interrupted Poisson process (IPP) for incoming traffic. First, we obtain an analytical model for the jitter on one node with respect to the phase probabilities, traffic load, and tagged traffic share in the aggregate traffic flow. Then, we analyze N-node cases, and propose a model for end-to-end jitter. Our analysis leads to some fast-to-compute approximations that can be used for future network design or admission control. Finally, we validate our analytical results by comparing them with previous results for limit cases, as well as with event-driven simulations. We propose the use of our results as guidelines for jitter evaluation of real IP traffic.

Generally a patient who was injected radiopharmaceuticals for nuclear medicine examination is not an object of isolation. Therefore, when the patient uses toilet, we expect surface contamination of a toilet by radioisotope. The measured value is $25.69Bq/cm^2$(a restroom near admission and administration), $19.39Bq/cm^2$(a toilet near department of radiology). The study shows that 9 of 24 locations in controlled area exceed over surface contamination limit. From now on, we should find source of contamination through measurement radioactive nuclide to apply radiation safety management.

College's existence is threatened through the decreasing of students, even though it made big growing. In these situations, College makes on-line contents for promotion and announce information of college. However, previous research has limit about statistic theory with influence of application and registration with an applicant for admission to a college. In this paper, we analyze difference of application and registration in period of application, and find the difference recognize rate with students by period of application.

The Main objective of this study is to find consumer attitude toward the Sanitary Regulation of Foods. In view of consumerism, this result will be used in re-regulating the law. Among the Sanitary Regulation of Foods, this study focuses on the Standard of prepackaged Food Labelling, because it is related both with the advertising from the food manufacturer's point of view and with the perception about the food itself from the consumer's point of view. After reviewing the previous studies and related provisions about the Standard of Prepackaged food Labelling, and compare other sanitary regulation of foods in developed countries (U.S.A. and Japan), basic research framework was derived. The research framework focuses on the user perception about the validity of provisions about the Standard of Prepackaged Food Labelling, and on the existance of exaggeration in food advertising using prepackaged foods. Data were collected through questionaires from the sample covering 374 food customers. The data were analyzed by frequency test and the important findings of this study are as follows. Most food consumers consider such provisions as date of manufacturing, circulation time limit, cautions for food handling, price, and manufacturer as important factors in buying food products. Among these factors, the date of manufacturing and circulation time limit are most critical factors, and must be labelled correctly on the prepackaged food cover. But other provisions which do not affect on consumer's buying decision (e.g. business admission number, self standard number) need not be labelled. From this study, we can conclude that the provisions about the standard of prepackaged Food Labelling currently used must be devided into two parts. One is 'mandatory provisions' which must be obeyed by all food manufacturets, and the other is 'autonomous provisions' which need not be obeyed by all food manufacturers. And mandatory provisions need to be regylated more strongly than now.

We propose an approximation of the M/G/1 system with finite workload capacity, where those customers whose admission to the system would increase the workload beyond a prespecified finite capacity limit are not accepted. Our approximation method is based on the idea that the service time of a customer in the M/G/1 system can be approximated as the sum of service times of a batch of customers in the $M^X/d/1$ system where the deterministic service time d is small enough. That is, the original service time is discretized and approximated by the batch size. We exemplified our method by obtaining the average workload of the M/M/1 system by means of the $M^X/d/1$ system, where the batch size is geometric. In addition, the approximate blocking probabilities of the M/M/1 and $M/E_k/1$ system with finite workload capacities are sought. The proposed method turns out to give a good approximation, which is compared with a simulation.

In this paper, we propose an approximation of the M/G/1 system with finite workload capacity, where customers whose admission to the system would increase the workload beyond a prespecified finite capacity limit are not accepted. Our approximation method is based on the idea that the service time of a customer in the M/G/1 system can be approximated as the sum of service times of a batch of customers in the $M^{X}/d/1$ system where the service time is deterministic and very small. That is, the original service time is discretized and approximated by the batch size. We exemplified our method by obtaining the average workload of the M/M/1 system by means of the $M^{X}/d/1$ system, where the batch size is geometric. In addition, the approximate blocking probabilities of the M/M/1 and $M/E_{k}/1$ system with finite workload capacities are sought. The proposed method turns out to give a good approximation, which is compared with a simulation.
