경비의 형태는 과거 인력 경비에서 현대에 이르러 기계경비로 점차 전환되고 있다. 이는 기계경비가 인력경비에 비해 효율적이기 때문이다. 하지만 기계경비 시스템의 운용에 있어 오경보로 인해 기계경비의 높은 기대효과에도 불구하고 발전을 저해하는 요소로 인해 기계경비의 성장을 더디게 하고 있다. 이에 본 논문은 연구는 IPA(Importance Performance Analysis)기법을 이용하여 기계경비 시스템 운용에 있어 결함성 측면의 제거가 기계경비의 발전에 있어 그 중요도가 얼마나 높은지를 살펴보고, 또한 기술적 측면에서 기계경비 시스템의 오동작을 최소화할 수 있는 복합형 방범 센서를 제시하고자 한다.

Objectives: This study aims to provide basic data for high-quality dental services. In addition, we will promote the operation of preventive dentistry that implements preventive measures. It was conducted to study the change of patient's treatment behavior and treatment cost due to the discontinuation of preventive dentistry in university dental hospitals. Methods: This study collected data using the integrated medical information system of the C University Dental Hospital. From September 1, 2017 to August 31, 2019, data were analyzed using frequency, percentage, mean, standard deviation, chi-square test using SPSS version 24.0 statistical program, and T-test. Results: There was a significant difference in the number of preventive dental treatment cases from 58.3% of preventive dental operation periods to 41.7% of preventive dental operation periods. As a result of comparing the medical expenses, the total medical expenses during the preventive dental operation period decreased from 521,308,872 won to 379,724,995 won during the discontinuation period, 141,583,877 won. The number of medical treatments by treatment behavior decreased 3,835 (28.4%) from a total of 13,520 preventive dental operation periods to 9,685. Conclusions: This study is meaningful as the first study to confirm the change in the treatment behavior and the change in the cost of treatment due to the discontinuation of the operation of preventive dentistry at university dental hospitals. In conclusion, it is thought that there is a possibility of the lack of accessibility and the limitation of professional preventive care due to the discontinuation of preventive dentistry.

This study investigates the one-year performance of the Seoul Metropolitan Rail Transit(SMRT) operation. It intends to provide a basic understanding for railway operation in Seoul Metropolitan Area and thereby for making rational transport policy. The paper is conceptually comprised of four sections; analysis of passenger travel characteristics; SMRT costing and traffic cost function: its operating characteristics in terms of finance and utilization; primary social benefits of SMRT and suggestions. In the first year of operation (1974), the average daily traffic was about 335,000, After the drastic increases of fare in both Subway and KNR rail-lines, the travel volume has been cut by almost 10 percent, though most pronounced on intra-Subway line. The spatial distribution of passengers indicates that travelers use the SMRT line mainly for uninterrupted direct travel toward the CBD. In the prospective costing, the opereting expenses are divided into three groups; those which vary directly with volume; those partially variable with volume; and those entirely unrelated to volume change, With this information, cost function was derived for varying schedules of operation. Primary social benefits of the SMRT are assessed, though preliminary. Account should be taken of the nature of common costs of the SMRT in fare-rate making, especially when much of the operating expenses are accounted for by the fixed costs such that the revenue may not readily turn into break-even. The accounting results of the one-year operation coincide reasonably well with the prospective costing estimates. According to the findings of this annd another travelers' behavior studies, managerial effort would bring more revenue gain to the SMRT than fare increase does, not to speak of greater social benefits by so doing.

Purpose: This study was performed to evaluate the impact of the lesser toe operation on the overall clinical outcomes, and to analyze the clinical results of concomitant surgery for hallux valgus and lesser toe deformities. Materials and Methods: Forty-six cases underwent surgery for hallux valgus with concomitant lesser toe deformities were followed up for at least 1 year. Lesser toe deformities consisted of 9 crossover toes, 10 claw toes, 12 hammer toes and 15 bunionettes. Clinical evaluation was performed according to AOFAS (American Orthopaedic Foot and Ankle Society) score, patient's satisfaction score, and pain VAS (visual analogue scale) score. Hallux valgus angle (HVA), intermetatarsal angle (IMA), and period to union were measured. Preoperative expectation about lesser toe deformities, postoperative satisfaction, complication rate, hospitalization period, medical expenses, and frequency of outpatient follow-up were analyzed. Results: AOFAS score, VAS score, HAV and IMA had improved significantly. On preoperative expectation of patients, correction of lesser toe deformities was ranked third, following the improvement of big toe(bunion) pain and the correction of hallux valgus. Patient's satisfaction score was average 92.8 points, and the importance of lesser toe operation was 30.2%. When compared to hallux valgus operation only, there were average 2.5 days of additional hospitalization, 2.4 times of additional outpatient follow-up, 386000 won of additional medical expenses. Conclusion: Combined operation for hallux valgus and concomitant lesser toe deformities showed good clinical results. When compared to hallux valgus operation only, there were longer hospitalization, more frequent follow-up, more medical expenses, more complications. However, lesser toe deformity correction in patients underwent hallux valgus operation is considerable, because of high preoperative expectation and postoperative satisfaction.

지난 호에 이어 2018년도 주요 의료판결을 정리하였는데, 특히 설명의무와 관련된 법원의 설시는 그 한계가 어디까지인지 알 수 없을 정도로 다기(多岐)하여 가급적 많은 판결을 소개하기 위하여 노력하였고, 손해배상의 범위와 관련하여 개호비를 다액 인정한 판결과 각서의 효력이 증가된 치료비에도 미치는 것으로 본 판결도 관심을 가져볼 필요가 있다. 진료비상계 및 공제관련 판결은 서술내용에 비하여 가장 많은 토론이 이루어졌다. 의료기관 다중 운영 사례는 중간적 판결이지만, 워낙 의료계에 관심이 많은 사건이고, 임의비급여 관련 재량권 일탈 남용이 인정된 사건도 과거에 비하여 비중이 많이 줄었지만 여전히 의미가 있다고 보았다.

The BTL project, 4 years since its operation. has benchmarked the PFI Project in Japan and has been introduced. Given the evaluation step to select a preferred bidder, in a technological factor, the basic plans are corrected and complemented, whereas in a price factor, the low price bidding system is being enforced. There is concern that how to select preferred bidders and how to operate project costs during operation and management period may be problematic. Thus, in this study, using the Analytic Hierarchy Process, the method of deciding the priority to select preferred bidders in an early stage of the project and the evaluation model to evaluate the validity of BTL project expenses in process of project enforcement are established. Targeting the group composed of experts who have experiences in the BTL project. Then, the levelling of evaluation factors and grouping have been carried out as following : LCC analysis and disbursement for government including two more detailed factors.
