In this paper, we proposed Backgorund Model Set algorithm for the speaker verification to improve the shortcoming of calculating process in conventional confidence measure(CM). CM is to display relative likelihood between recognized models and unrecognized models. Unrecognized models is known as antiphone models. Calculate probability and standard deviation using all phonemes at process that compose antiphone model. At this process, antiphone CM brought bad result. Also, recognition time increases. In order problem, we studied about method to reconstitute average and standard deviation taking BMS algorithm using antiphoneme that near phoneme of CM calculation.

소프트웨어 산업의 발전에 따라 소프트웨어 개발조직에서는 소프트웨어 품질이 중요한 이슈로 부각되었다. 특히 여러 종류의 테스트 성숙도 모델을 통해 조직의 소프트웨어 테스트 성숙도 향상에 대해 다양한 방면으로 시도하고 있다. 하지만 현재 테스트 성숙도를 측정할 수 있는 모델들은 기존의 개발 성숙도 측정 모델을 기반으로 개발하여 테스트 부분에 대한 언급이 부족하고 단지 테스트 성숙도 레벨만을 측정하였다. 이러한 문제점을 해결하기 위해 소프트웨어 개발프로세스와 한께 테스트 프로세스를 수행할 수 있도록 이중 V모델과 테스트 성숙도의 용이한 평가를 위한 테스트 평가 속성과 레벨을 정의한 테스트 속성과 상호관련 매트릭스를 제안하였다. 테스트 프로세스 개선(Test Process Improvement: TPI)의 개선제안(Improvement Suggestion) 방법을 통해 테스트 성숙도 모델 확장하고, 측정된 성숙도를 향상시킬 수 있는 개선방향을 제시한다. 또한, 본 연구에서 제안하는 테스트 성숙도 상호관련 매트릭스는 테스트 성숙도를 정량적으로 평가하기 위해 사용하였다. 결과적으로는 확장된 테스트 성숙도 모델을 통해 조직의 테스트 성숙도를 높이는데 기여 할 수 있으리라 생각한다.

Background Congenital muscular torticollis (CMT) is a common musculoskeletal disorder in children. Secondary scoliosis can occur in patients with CMT; however, the extent of inclination and improvement of scoliosis after surgical correction of CMT have not been adequately studied. In this study, we aimed to evaluate and measure the improvement in vertebral tilting after surgical correction according to age at the time of surgery. Methods Between June 2007 and January 2020, 831 patients with CMT underwent sternocleidomastoid release. Among them, 426 patients were enrolled, and their medical records were retrospectively reviewed. Ultimately, 210 patients available for radiological evaluation and analysis were enrolled in this study. The patients were divided into four groups according to age at the time of surgery to determine the relationship between age and changes in scoliosis. Results Our findings showed an improvement in scoliosis in all age groups after surgery. The results for follow-up after 1 year confirmed long-term improvement in vertebral tilting. The degree of improvement in scoliosis was significantly higher in the younger age group than in patients aged 18 years or older. Conclusion The effect of surgical release on scoliosis was significant in all age groups. The findings of this study suggest that CMT should be corrected before the age of 3 years to ensure an optimal surgical mitigation of scoliosis. Furthermore, in cases of neglected CMT, surgical release should be actively attempted because there is significant improvement.

The rapid advances in high power light sources and arrays as encountered in incandescent lamps have induced dramatic increases in die heat flux and power consumption at all levels of high power LED packaging. The lifetime of such devices and device arrays is determined by their temperature and thermal transients controlled by the powering and cooling, because they are usually operated under rough environmental conditions. The reliability of packaged electronics strongly depends on the die attach quality, because any void or a small delamination may cause instant temperature increase in the die, leading sooner or later to failure in the operation. Die attach materials have a key role in the thermal management of high power LED packages by providing the low thermal resistance between the heat generating LED chips and the heat dissipating heat slug. In this paper, thermal transient characteristics of die attach in high power LED package have been studied based on the thermal transient analysis using the evaluation of the structure function of the heat flow path. With high power LED packages fabricated by die attach materials such as Ag paste, solder paste and Au/Sn eutectic bonding, we have demonstrated characteristics such as cross-section analysis, shear test and visual inspection after shear test of die attach and how to detect die attach failures and to measure thermal resistance values of die attach in high power LED package. From the structure function oi the thermal transient characteristics, we could know the result that die attach quality of Au/Sn eutectic bonding presented the thermal resistance of about 3.5K/W. It was much better than those of Ag paste and solder paste presented the thermal resistance of about 11.5${\~}$14.2K/W and 4.4${\~}$4.6K/W, respectively.

The emission standard of diesel engine on the construction equipment has been rapidly enhanced in advanced countries, because most of air pollutions was caused by construction equipment. So, all of the construction equipments will be tested for emission with standard measurement mode. But, the standard measurement mode of construction equipment is different for non-road and one for the road in korea. This study was conducted to measure emission characteristics of the construction equipment with changed standard measurement mode and to improvement the emissions experimentally.

Recently, the LISI(Level of Information System Interoperability) model has been used to measure level of interoperability in the Ministry of National Defense. This study is proposed for improvement of interoperability level measurement method. The MND has been devoting a lot of effort to ensure defense weapon system interoperability. They enacted related regulations and developed SITES for measuring the level of interoperability. However, the LISI model has problems with using just only DITA and applying MND-AF based on Architecture development. To overcome these problems, this paper proposes how to apply reference model to LISI Model and how to apply LISI Model to MND-AF architecture development.

Purpose: This research aims at quality improvement of website services on the internet. Methods: SERVQUAL is redefined for web environments as sixteen statements in five dimensions to identify user requirements for websites and measure their importance ratings. Quality Function Deployment (QFD) is used to integrate user requirements into service development for websites so that management and design guidelines can be obtained for user-oriented websites. Fuzzy set theory is introduced to resolve the ambiguity and subjectivity of user requirements in the House of Quality (HOQ). Results: The priorities of design characteristics are extracted from the Fuzzy QFD for University websites. Conclusion: It is expected to provide quality services in less time with less effort, if the results of the Fuzzy QFD are used to provide services in a strategic way under limited resources.

Performance measurement systems based on the principle that "if you can't measure it, you can't manage it" reinforce a short-term culture by focussing on tangible outputs. Instead, the focus of organisations should be on sustainable long-term performance through continuous systemic improvement. To establish and reinforce behaviours that drive systemic improvement, measurement and reporting systems need to be de designed to re-enforce work to role behaviour by managers. This paper discusses this concept and how it is being applied in practice through an ongoing action research project.

The effort to measure and improve the quality of healthcare is a common health policy issue worldwide. Korean Value Incentive Programme is one of that effort, but some concerns exist. Compared to pay for performance program in other countries, it measures healthcare quality with relatively narrow performance domain using a small number of clinical indicators. It was designed without involving hospitals and other key stakeholder, and program participation was mandated. Highest and lowest performers get bonus and penalty using relative ranking. As a suggestion for development, the direction for quality management at the national level should be given first. Therefore the philosophy or strategy for quality improvement should be reflected to the program. And various domains and indicators of healthcare quality should be developed with active communication with healthcare providers. The evaluation method is necessary to be changed to provide achievable goal to the healthcare providers and attract quality improvement.
