In pointer adjustment systems, 3 byte SDH clocks are controlled for synchronization. Therefore large jitter is generated in that systems. Bit stuffing technique was introduced as method for reducing pointer adjustment jitter. However, the jitter generated in this systems is also not so small. In this paper, the problems in the bit leaking system are analyzed and new bit stuffing technique is introduced to reduce the jitter sufficiently.

교합조정은 비가역적인 술식이므로 예방적인 목적으로 사용하는 것은 바람직하지 않으며 환자가 증상을 호소하거나 환자의 구강검사시 교합간섭으로 인한 증상이 확인된 경우라도 자연치에서의 교합조정술은 반드시 신중을 기해야 한다. 교합조정술을 시행하기 전에 먼저 하악의 위치가 안정되어야 한다는 것을 명심하고 이를 위해 치과의사는 하악의 중심위에 대한 이해와 중심위로의 하악유도 방법에 대한 숙지도 필요하다. 또한 심한 악관절 장애나 통증 및 불안정한 하악의 위치를 보이는 경우 구강내 교합상이나 교합 안정장치가 선행되어야 하는 경우가 있다. 교합조정술을 시행해야 하는 치과의사 자신이 교합조정술에 대한 지식을 충분히 습득하고 있어야 하며, 교합조정술의 적응증을 분명하게 확인한 뒤 조심스럽고 정확하게 시술을 시행해야 한다. 즉, 잘못된 교합조정으로 오히려 교합간섭을 야기할 수도 있음을 명심해야 한다. 그러나 교합조정에 대해 올바로 이해하고 일반적인 교합조정의 원칙을 지켜 정확히 시행한다면 교합조정은 결코 환자에게 해를 주지 않고, 자유로운 하악운동을 가능케 하며, 교합의 안정성을 유지해 줄 것이다.

Criminal Mediation System in Korea, it did pilot operation by Crime Victim Support Centers such as Daejeon and other two District Prosecutors' Office in April 2006. And starting 2007, Crime Victim Support Centers and Criminal Mediation System conducted from 57 District Attorney's Office and Branch Offices and now 2016, Criminal Mediation System is operated in all the District Attorney's Office. On the other hand, the Attorney General's Office established the 'Criminal mediation practical operating instructions' in October 2009 and created its legal basis at "Crime Victims Protection Act" in September 2010. It seems that the criminal mediation have to operate as the direction for supporting crime victims recovery. However, it seems that the overall infrastructure of the criminal mediation system is built. But I have experienced this through G Attorney's Office as a Criminal mediator activity from 2007 to 2016 now, some issues have emerged such as weak on personal safety in criminal mediation room, etc. Thus, in this paper, I will examine the problems about this and propose improvements of criminal mediation system to fit the practical criminal mediation.

This study was carried out recognition and status changes of optician for glasses fitting. It based on a survey results of twice in relation to the glasses fitting. The results are as follows. The ratio of glasses fitting about optician operation appeared to increase gradually. The positive awareness change appeared from the customer and optician about the cost charging about the glasses fitting. In the case of a plastic glasses, the burden for the inconvenience feeling and fitting frequency showed an increase with relation to the temple fitting. To reduce the burden of glasses fitting, The continuous education for the correct glasses usage need.

Electrical resistance tomography (ERT) is an imaging technique where the internal resistivity distribution inside an object is reconstructed. The ERT image reconstruction is a highly nonlinear ill-posed problem, so regularization methods are used to achieve desired image. The reconstruction outcome is dependent on the type of regularization method employed such as l2-norm, l1-norm, and total variation regularization method. That is, use of an appropriate regularization method considering the flow characteristics is necessary to attain good reconstruction performance. Therefore, in this paper, regularization methods are tested through numerical simulations with different flow conditions and the performance is compared.

원격조정 시스템에서 힘정보는 중요하다. 그러나 특수 응용 분야에 적합한 크기와 측정의 정확성을 가지는 힘 센서의 적용은 매우 어렵다. 더욱이 힘 정보의 전송으로 인한 시간지연으로 시스템은 불안정 되기 쉽다. 본 논문은 가상환경을 이용한 원격조정 시스템을 제안하였다. 시스템은 그래픽 시뮬레이션 처리부, 슬레이브 제어부 그리고 역감 제시부로 구성되어진다. 슬레이브 암이 작업물체와 접촉작업을 할 때 역감은 가상환경에서 계산되어지므로 힘 선세와 시간지연으로 발생되는 문제점을 해결 할 수 있다. 제안된 시스템으로 접촉작업에 대한 힘 제시 원격조정을 수행하였고, 실험결과를 통해서 안정된 접촉작업을 확인하였다.

In this paper we propose a new shaping algorithm which can control the shaping delay and the output buffer size based on the leaky bucket counter with a threshold value. This paper assumes that input traffic of the proposed shaping algorithm is the worst case traffic tolerated by the continuous leaky bucket algorithm and claracterizes traffic patterns that can depart from our shaping algorithm. We also compare shaping delay and output buffer size of the proposed algorithm with the existing shaping algorithm without a threshold value. Our results show that the proposed shaping algorithm can easily manage the shaping delay and output buffer size than any other mechanism.

기계 독해란 주어진 문서를 이해하고 문서 내의 내용에 대한 질문에 답을 추론하는 연구 분야이며, 기계 독해 문제의 종류 중에는 여러 개의 선택지에서 질문에 대한 답을 선택하는 객관식 형태의 문제가 존재한다. 이러한 자연어 처리 문제를 해결하기 위해 기존 연구에서는 사전학습된 언어 모델을 미세조정하여 사용하는 방법이 널리 활용되고 있으나, 학습 데이터가 부족한 환경에서는 기존의 일반적인 미세조정 방법으로 모델의 성능을 높이는 것이 제한적이며 사전학습된 의미론적인 정보를 충분히 활용하지 못하여 성능 향상에 한계가 있다. 이에 본 연구에서는 기존의 일반적인 미세조정 방법에 템플릿을 적용한 템플릿 기반 미세조정 방법을 통해 사전학습된 의미론적인 정보를 더욱 활용할 수 있도록 한다. 객관식 형태의 기계 독해 문제 중 하나인 토익 문제에 대해 모델을 템플릿 기반 미세조정 방법으로 실험을 진행하여 템플릿이 모델 학습에 어떠한 영향을 주는지 확인하였다.

This paper examines whether debt ratio effects earnings management. There are various methods that estimate earnings management. This paper examines whether these methods impact on the relationship between earnings management and debt ratio. In addition, this study examines whether these relationship effects of debt type. Previous studies in this area haven't examined the relationship between debt ratio and earnings management in Korea. These studies didn't consider earnings management's method to analysis for this relationship. This paper tests the relationship between earnings management and debt ratio with methods of earnings management unlike from previous studies. Results are summaried as following. First, the relationship between debt ratio and earnings management was different for these methods. Abnormal Accruals that used estimation of eanrnings management in previous studies didn't examine these results that debt ratio effects of earnings management. However, it was significant positive the relationship between real activity management and debt ratio.

Earnings management is a collection of management decisions which firms do not report the true performance. Many prior studies suggest that earnings management could be the results of either managerial earnings management or manager's private information for future performance. This study attempts to delve into the fundamental implications inherent in earnings management by analyzing how earnings management affects future firm performance in public institutions. If discretionary accruals as a measurement of earnings management embrace manager's private information, it will have a positive effect on future performance in succeeding period. In contrast, if discretionary accruals embrace manager's opportunistic earnings management, it will have a negative effect on future performance in succeeding period. Empirical findings are summarized as following.: Earnings managements are negatively associated with future firm performance for all succeeding period. This negative relationship continues for all succeeding period. The overall results can be serve as a evidence that the discretionary accruals capture opportunistic earnings management on average.
