The committee of admitted doctors developed a questionnaire regarding medical dispute and distributed it to 1,600 members of Korean Academy of Orthodontics. The questionnaire consisted of three categories and 56 items covering basic information about the doctors and patients who had experienced medical disputes, the cause and workaround of medical accidents, and methods for taking precautions. The present survey showed a similar proportion of responders who had experienced a medical accident compared to the study in 1997. The primary reason for medical disputes was dissatisfaction with appearance. Many doctors felt that they would likely experience a medical dispute at some point. Most disputes were settled by doctors themselves, usually for an amount of less than 5 million Korean won. For some doctors, medical accidents lead to ongoing psychological problems. Responders felt that continuing education for medical dispute is very necessary. These results reveal a need for the association of orthodontists to lead advancements in education and countermeasures for preventing and managing medical accidents and disputes.

Background and Objectives： The introduction of highly sensitive imaging techniques has made it possible to detect many non-palpable nodules, or“incidentaloma”in the thyroid. Discovery of these lesions raises concerns about their malignancy, but the optimal strategy for managing these lesions has not been clearly established. This study was designed to evaluate the usefulness of ultrasonographic exam with new diagnostic criteria and presume the value of mass screening for thyroid cancer. Materials and Methods : Mass screening for thyroid cancer were carried out in conjunction with mass screening for breast cancer. The subjects were 630 women aged 30 years or over. Thyroid glands were examined with 10 MHz transducer ultrasonography by one radiologist. Needle aspiration biopsy were performed when suspicious of malignancy under the new diagnostic criteria. Results and Conclusion : The new ultrasonographic criteria to diagnose thyroid cancer provided useful information and ensured more accurate evaluation. 7 cases of thyroid cancer were discovered and successfully managed. It should be further demonstrated that there is sufficient value of mass screening for thyroid cancer to perform it independently despite early cancer detection.

Since radio communications based train control system requires considerable amount of information than track circuits based signalling system and these information have significant effects on train control system safety, it is essential to ensure information integrity. In addition, when track information has to be added or changed due to track installation, track maintenance (both corrective and preventive), any information changes must be reported to train control system as soon as possible. In this paper, we provide explanation on the equipment and its data structure. Also, we represent the results of a simulator application to check the information integrity generated by the equipment.

This second study on the effectiveness of nursing organization was designed to test the relationships between effectiveness of nursing organizations and structural variables that had been significant variables in the first study, the group design variable and the personal characteristic variables that had not been analyszed in the first study based on personal resource productivity model. The data were collected through self-reported questionnaires completed by 605 nurses working in hospitals in seoul and 782 patients being hospitalized in 5 tertiary hospitals in Seoul. The results showed that according to the canonical correlation analysis, the managing job design, nursing delivery system. nurse's age, career. and formalization were revealed as predicting variables of a nurses' job satisfaction and patients satisfaction among the five hospitals. Hospitals in which the team nursing method was used showed a higher score in nurses' job satisfaction and patient satisfaction than in hospitals which used the functional nursing model.

Various risk factors affect construction projects. Due to the uncertainties created by risk factors, actual activity durations frequently deviate from the estimated durations in either favorable or adverse direction. For this reason, evaluation of schedule uncertainty is required to make decisions accurately when managing construction projects. In this regard, this paper presents a new computer simulation model - the Repetitive Schedule Risk Analysis Model (RSRAM) - to evaluate unit-based repetitive building project schedules under uncertainty when activity durations and risk factors are correlated. The proposed model utilizes Monte Carlo Simulation and a Critical Path Method based repetitive scheduling procedure. This new procedure concurrently provides the utilization of resources without interruption and the maintenance of network logic through successive units. Furthermore, it enables assigning variable production rates to the activities from one unit to another and any kind of relationship type with or without lag time. Details of the model are described and an example application is presented. The findings show that the model produces realistic results regarding the extent of uncertainty inherent in the schedule.

The aim of this paper is to show the process of R&D Project-Priority Ordering in the Defense Technology field. We propose specific methods (Delphi, Analytic Hierarchy Process (AHP), Scoring) to order the R&D Project-Priority. In general, to decide the priority of R&D projects most of researches depend on questionnaires which are surveyed by experts. However, it is criticized that this process cannot reflect the limitation of experience and knowledge of experts. In this process, we separate evaluators in two parts: the first is strategic experts, the second is technical experts. Evaluators can choose and evaluate the alternatives which they are familiar with, so we can obtain reliable results. Finally, based on our process of the R&D Project-Priority Ordering we formulate policy implications for managing the defense technology.
