As the first step to improve the medical recording for the hospitalized patients, we tried to identify problems of completion rate of the medical recording and made the completion rate of the medical recording within due date known to the public in the hospital and commended the best Department and resident officially. The results were as follows: 1. The average number of the medical recordings per a recorder by years of residency(average number to quorum) was 293.3(398.8) in 1st year, 82.5(68.1) in 2nd year, 21.2(8.3) in 3rd year, and 20.5(1.9) in 4th year-residents. There was only 2 residents who prepared the medical recordings more than the average of 125.6 recordings per a resident. 2. Among 13 Departments, the medical recording was wholly put in charge of the 1st year-resident in 6 Departments. The duty was shared with the 2nd year-resident in 5 Departments and the 3rd year-resident in 1 and the 4th year-resident in Only 1 Department. 3. The more the cases requiring the medical recording, the lower the completion rate(80% less than 100 recordings, 70% in 100-299, 60% in 300-399 and 33.3% in more than 400). 4. There was no difference in the completion rate of the medical recording before(1991) and after(1993) a public nitice(1992). However, 4 Departments showed improvement of 21-45% in the completion rate, and no case was found where billing for medical assurance was postponed due to delayed completion of the medical recording. 5. The completion rate was relatively low(72-78%) from January to March. The main reasons were shortage of men power due to preparation of board examination, attendance to military duty, and lack of training in the medical recording for the new 1st year-residents. 6. The official commendation of the best Department and resident by letters did not improve the completion rate of the medical recording. In conclusion, The main reason of the low completion rate of the medical recording was the fact that the 1st year-residents were almost exclusively responsible for the medical recording. Hence, it is mandotory that this practice gets staffs' attention to improve the completion rate. Public notice of the completion rate of the medical recording shows prompt improvement of the completion rate. Prize money rather than commendation by a letter for the best Department would also be more effective to improve the quality of medical recording.

Purpose - This paper analyzes the student determinants of college non-completion and estimates the effects of each determinant on college non-completion. Design/methodology/approach - We use student panel data from a large Korean university from 2011 to 2021. Our results are from estimation of fixed-effects logit model. Findings - The results show that grade point average, participation in extracurricular activities, the number of counseling sessions with teachers, and financial aid are the main determinants of college non-completion. Academic probation, which is defined as any person who has a cumulative grade point average below a one point seven five, increases the non-completion rate by 2.6 percentage points and an one-point rise in extracurricular activities index reduces the rate by 0.1 percentage points. The effects of each determinant are heterogeneous across student sub-groups which are separated by gender, nationality, and academic discipline. Research implications or Originality - Tailored support programs for academically discouraged students that incorporate student characteristics and backgrounds are necessary to increase college completion rates and degree attainment.

From January to March in 1979 and 1982, the vaccination rate of B.C.G., D.P.T and Sabin with 392 infants who were registered at M.C.H. room in a Health Center in Seoul were as follows: 1 There were no specific relations between the sex and the vaccination for B.C.G., D.P.T. and Polio. 2. In 1982, the younger the mother's age was, the higher the vaccination rate for B.C.G. was. For the D.P.T. and Polio the rate of above 35 year group was the highest but the completion rate of the vaccination and the regular vaccination rate were the highest in the age of 30-34 year group. 3. In 1982. the higher the educational levels of tile mother were, the higher the vaccination rates for B.C.G., D.P.T. and Polio were. 4. The vaccination rate for B.C.G. within a month after birth was the highest in Salaried laborer group. The completion rate of the vaccination and regular vaccination rate for D.P.T. add Polio were also the highest in salaried laborer group. 5. In 1982, the rates of all vaccination for B.C.G. were tile highest in the first child. The completion rate of the vaccination and regular vaccination rate for D.P.T and Polio were also the highest in the first child in 1982.

소프트웨어 복잡도가 증가할수록 소프트웨어 성공률은 기하급수적으로 감소하며, 반대로 실패율은 증가한다. 소프트웨어 규모 증가에 따른 실패율은 성장곡선으로 표현할 수 있다. 이 현상에 따라, 본 논문은 Gompertz 성장곡선으로 개발 성공률과 완료율을 추정하였다. 먼저, 수치적으로 제시된 $10^n$의 소프트웨어 규모를 로그값으로 변환시켜 데이터 간격을 일정하게 하였다 로그값의 소프트웨어 규모 변화에 따른 개발 성공률과 완료율의 함수관계를 유도하고자 하였다. 그러나 이 관계를 적절히 표현하는 함수를 찾지 못하였다. 따라서 본 논문에서는 개발 성공률의 역 개념인 실패율과 완료율의 역 개념인 취소율을 도입하였다. 로그값의 소프트웨어 규모 변화에 따른 개발 실패율과 취소율 관계는 성장곡선 형태를 나타내었다. 결론적으로, 개발 취소율과 실패율을 적절히 표현하는 함수로 Gompertz 성장곡선을 적용한 결과 실측 데이터를 적절히 표현할 수 있었다. 본 모델을 적용하면 특정 규모의 소프트웨어에 대한 개발 성공률과 완료율을 보다 정확히 얻을 수 있을 것이다.

Background: Completion thyroidectomy is defined as the surgical removal of the remnant thyroid tissue following procedures less than total or near-total thyroidectomy. Although some authors advocate subtotal thyroidectomy with lower complication rates, total or completion thyroidectomy have been defended by others because of the improved survival and lower morbidity that is comparable with subtotal thyroidectomy. Objectives: The purpose of this paper is to review the necessity and safety of completion thyroidectomy for differentiated thyroid carcinoma(DTC). Materials & Methods: During the past 10 years(1986 to 1996) , authors have performed 211 total thyroidectomy. Ten of these patients were treated by completion thyroidectomy for DTC. Initial operation of 7 patients had been performed at St. Vincents Hospital and 3 patients at other hospital. The medical records of patients undergoing completion thyroidectomy were retrospectively reviewed. Results: The completion thyroidectomy specimen contained residual tumor cells in 8 of the 8 patients with papillary carcinoma and none of the two patients with follicular carcinoma. Complications of completion thyroidectomy were transient hypoparathyroidism in two patients and transient unilateral recurrent laryngeal nerve palsy in one patient. But permanent complications were not noticed. Conclusion: We recommend completion thyroidectomy as an efficient and safe method of surgical treatment with a low complication rate for DTC.

In this paper, we study how to optimize the data shuffle phase by leveraging the flow relationship in datacenter networks (DCNs). In most of the clustering computer frameworks, the completion of a transfer (a group of flows that can enable a computation stage to start or complete) is determined by the flow completing last, so that limiting the rate of other flows (not the last one) appropriately can save bandwidth without impacting the performance of any transfer. Furthermore, for the flows enter network late, more bandwidth can be assigned to them to accelerate the completion of the entire transfer. Based on these characteristics, we propose the flow chasing algorithm (FCA) to optimize the completion of the entire transfer. We implement FCA on a real testbed. By evaluation, we find that FCA can not only reduce the completion time of data transfer by 6.24% on average, but also accelerate the completion of data shuffle phase and entire job.

In this paper, we study a single-machine scheduling problem with deteriorating processing time of jobs and multiple rate-modifying activities which reset deteriorated processing time to the original processing time. In this situation, the objective function is to minimize total completion time. First, we formulate an integer programming model. Since the model is difficult to solve as the size of real problem being very large, we design an improved genetic algorithm called adaptive genetic algorithm (AGA) with spontaneously adjusting crossover and mutation rate depending upon the status of current population. Finally, we conduct some computational experiments to evaluate the performance of AGA with the conventional GAs with various combinations of crossover and mutation rates.

Present study was performed to compare different types of teleoperation performance measures. A modified Cooper-Harper rating scale and a distance measure were newly introduced and compared to two traditional measures, the error rate and time-to-completion. Participants performed a simulated telerobotic task with varying visual display interfaces. The results of correlation analyses revealed that the modified Cooper-Harper ratings had a close association with the error rate measure. The distance measure also appeared to be a consistent performance measure, which accounted for both the error rate and time-to-completion. A further analysis, however, showed that the effectiveness of each performance measure varied with the level of task difficulty. The results imply that the choice of performance measure should be made based on the task difficulty as well as the particular task being studied. The results revealed here also have implication for performance measures of various display and control systems including aircraft navigation displays and tactical displays.
