  • Purpose: This study aimed to examine the necessity of administrative compensation insurance and claims cases during the emergency medical service process among administrative compensation insurance cases and suggests problems and improvement measures. Methods: We compared the details of administrative compensation insurance claims of 15 cities and provinces, excluding Seoul and Kwangju, from 2017 to 2020 by requesting details disclosure of the comprehensive deduction for administrative compensation in 17 cities and provinces across the country. Results: A total of 69 cases were compensated through the administrative comprehensive compensation deductions. There were 53 cases of damage that occurred at the field stage, 14 cases at the transfer and hospital stage, and two other cases. Conclusion: The 119 paramedics, which are the perpetrators, should be active in field activities and free from the psychological pressure caused by increased workload and litigation. Active compensation administration is required for damage cases occurring in the firefighting activities context.

  • The main goal of our research is to compensate the milled surface errors induced by the tool deflection effects, which occur during the milling process. First, we predict cutting forces and tool deflection amount. Based on predicted deflection effects, we model milled surface shapes. We present a compensation methodology , which can generate a new tool trajectory, which is determined so as to compensate the milled surface errors. By considering manufacturing tolerance, tool path compensation is generalized. To validate the approaches proposed in this paper, we treat an illustrative example of profile milling process by using flat end mill. Simulation and experimental results are shown.

  • For the development of compensation machining program, ultra precision grinding used in ultra precision machine and corrective machining was studied. We explored a new rough grinding technique on optical material such as zerodur. The facility used is a polishing machine with a custom grinding module and a range of diamond resin bond wheel. Surface roughness and form accuracy are measured by surface measurement equipment(Form Talysurf series2). Our compensation machining program has complied with a target of producing surface roughness better than $0.05{\mu}m$ Ra and form accuracy of around $0.05{\mu}m$ Rt and has been unveiled as a work-hour model.

  • In a transfer line with mass production capability, calibration systems are included in the process as a separate dedicated station. However, this method is not appropriate in an unattended FMC with flexibility. As the FMC produces vesatile parts with small batch sizes, more flexible calibration systems are required. In this paper, a calibration/inspection system suitable for an unattended turning cell is introduced. The system has functions of dimension calibration of parts by touch probes, tool wear compensation, and quality monitoring of parts. Furthermore, characteristics of errors in the system are identified and corresponding compensation methodology is suggested. An operation software was developed for efficient use of the system.

  • 본 논문에서는 컬러 보정차트를 이용한 디지털 영상의 컬러 보정 알고리즘을 제안한다. 제안된 알고리즘은 기준 컬러 값과 영상으로부터 취득된 컬러 값 사이의 컬러 변환 관계를 계산하기 위하여 별도의 컬러 보정 차트를 이용한다. 기존의 컬러 재현 알고리즘은 취득된 영상에 대한 컬러 스펙트럼 분석 및 디지털 영상의 형성 과정에 대한 모델링 등을 통한 방법을 이용하여 취득된 영상에 대한 컬러를 보정하는 방법을 주로 이용한다. 제안된 알고리즘은 차트로부터 제공되는 기준 영상과 취득된 영상의 컬러 사이의 변환 관계를 이용하여 컬러 보정 과정을 수행한다. 제안된 알고리즘은 두 단계로 수행된다. 컬러 보정의 첫 번째 단계에서는 컬러 차트의 영상을 취득한 다음, 내부의 기준 컬러 값과 차트 영상으로부터 취득된 컬러 값 사이의 변환 관계를 계산한다. 두 번째 단계에서는 계산된 변환 관계를 이용하여 차트 영상과 유사한 조건에서 촬영된 영상에 대한 컬러 보정을 수행한다. 제안된 알고리즘의 성능을 평가하기 위해서 다양한 조건 하에서 실험을 수행하였으며, 이를 일반적인 상용프로그램들의 컬러 보정 성능과 비교 및 평가하였다.

  • In this study, we introduce research aimed at minimizing machining errors without compromising productivity by compensating for the machining errors caused by tool deformation. Our approach experimentally establishes the direct correlation between cutting depth and machining error, and creates predictive models using mathematical functions. This method allows for the prediction of compensated cutting depths to obtain the desired cutting profiles, thereby maximizing the compensation of machining errors in the cutting process.

  • In general, manufacturing error is originated from bad material, machine tool defection and tool breakage. When the manufacturing process is stable, the most of error come from the tool wear. In common on-machine measurement teaching probe and touch sensor are widely used however in this paper the electric touch point type automatic tool compensation system is developed the performance of it is validated and effective operating is proposed.

  • This paper describes the possible undesier-able side effects that thyristor controlled compensation may have upon in several relays. This process consisted of calculating line conditions for each of the fault, compensation and loading levels. In some cases their effectiveness at coordinating compensated lines is lost, as they no longer can always accurately determine "distances" to faults.

  • Purpose: This study investigates the relationship between service compensation, consumer sentiment and revisit intention for service recovery in the Chinese foodservice industry, and the moderating effect of employee authenticity. Methods: Data were collected from people who experienced eating out in a city located in central China, and the hypothesis was verified through multiple regression analysis and hierarchical regression analysis. Results: The results indicate that the specificity of compensation affects both positive and negative emotions of customers, and the activeness of compensation also influences positive emotions of customers. Also, employee autheticity moderates the effect of specificity of compensation on customers' positive emotions. Both positive and negative emotions of customers influences revisit intention. Conclusion: These results show that the role of service compensation is important in service recovery in the rapidly expanding Chinese foodservice industry. In addition, since the sincerity of employees plays an important role in maximizing the recovery effect in the process of service recovery, it suggests that it is important not only to improve services in the quantitative aspect but also in the qualitative aspect through employee training.

  • 본 논문에서는 PVT(process, voltage, and temperature) 변화에 대한 보상기능을 가지는 시간-디지털 변환기(time-to-digital converter : TDC)를 제안한다. 일반적인 지연 라인(delay line) 기반의 TDC는 인버터의 전파 지연을 기반으로 시간을 측정하기 때문에 근본적으로 PVT 변화에 민감하다. 이 논문은 PVT 변화에 의한 전파 지연을 보상하여 TDC의 해상도 변화를 최소화시키는 방법을 제안한다. 또한 넓은 입력 측정 범위(detection range)를 갖기 위해 Cyclic Vernier TDC (CVTDC) 구조를 채택한다. 제안하는 PVT보상 기능의 CVTDC는 45nm CMOS 공정으로 설계되어, 8mW의 전력을 소모하며, 5 ps의 TDC 해상도 및 약 5.1 ns 입력 측정 범위를 갖는다.
