  • Recently, researchers show growing interest on product quality characteristic dependence and designing acceptance sampling plans under the quality dependence. This research intends to resolve a few theoretical and practical questions for better application of acceptance sampling when the quality characteristic of product items exhibits a statistical dependence and samples are inspected according to the production order. In this research, a mathematical programming model is developed for the economic modeling of sampling plans based on two evaluation criteria : the average outgoing quality(AOQ) and the average total inspection cost. An efficient solution procedure is then proposed using the functional structure of the two evaluation criteria and the procedure is numerically illustrated.

  • The goal of this thesis is to support safety and reliability characteristics of software intensive critical systems. The verification method developed is innovative from current state of the art in what concerns the verification viewpoint adopted: focusing on software faults, and not, like many other approaches purely on fulfilling functional requirements. As a first step and based on a number of well defined criteria a comparison was made of available literature in the area of static non formal non probabilistic software fault removal techniques. But, None of the techniques evaluated fulfilled all criteria set in isolation. Therefore a new technique was developed based on a combination of two existing techniques: the FMEA and FTA. These two techniques complement each other very well. It is possible to integrate both techniques with commonly used techniques at system level. The resulting new technique can be shown to combine nearly all aspects of existing fault removal techniques.

  • This paper proposes delay-dependent stability conditions of the fuzzy Markovian jumping Hopfield neural networks of neutral type with time-varying delays. By constructing a suitable Lyapunov-Krasovskii's (L-K) functional and utilizing Finsler's lemma, new delay-dependent stability criteria for the systems are established in terms of linear matrix inequalities (LMIs) which can be easily solved by various effective optimization algorithms. A numerical example is given to illustrate the effectiveness of the proposed methods.

  • 공통평가 기준(CC, Common Criteria)은 정보 보호 제품, 즉 IT제품에 대한 보안성을 평가하기 위한 국제 평가 기준이다. 그러나 개발자 측면에서는 CC 에서 정의된 보안 기능 사항 중 IT제품 개발에 있어서 어떤 보안기능을 요구하며, 적용 가능한 IT기술에는 무엇이 있는지 알기 어렵다. 이 때문에 평가를 받고자 할 때 제출물을 작성하거나 IT제품 개발에 있어서 많은 시간과 인력이 필요하게 된다. 본 논문은 IT제품 개발자를 위해 공통평가 기준에서 정의하여 서술된 보안기능항목을 이해하고 적용 가능한 IT기술에는 어떤 것 들이 있는지 제시하기 위한 도구를 개발하기 위해 CC(Ver3.1)2부 보안기능 요구사항 중 프라이버시 클래스만을 해결할 수 있는 S/W를 개발 및 프로토타이핑 하였다.

  • PURPOSE: This study examined the effects of both lower extremities proprioceptive neuromuscular facilitation training with functional electrical stimulation on the balance and gait of stroke patients. METHODS: Ten patients with stroke were divided randomly into two groups of five patients each who met the selection criteria. The training was conducted five times a week, for 60 minutes. The experimental group received both lower extremities proprioceptive neuromuscular facilitation training with functional electrical stimulation while the control group received general physical therapy with functional electrical stimulation. RESULTS: The timed Up-and-Go (TUG) test result was statistically significant after the intervention in the experimental group (p<.041). Berg Balance Scale (BBS) assessment was statistically significant after the intervention in the experimental group (p<.047) and between the experimental and control groups (p<.012). The cadence assessment was statistically significant after intervention in the experimental group (p<.031) and between the experimental and control groups (p<.015). The stride length assessment was not statistically significant after intervention in the experimental group and between the experimental and control groups. Gait velocity assessment was statistically significant after the intervention in the experimental group (p<.031) and between the experimental and control groups (p<.015). CONCLUSION: Both lower extremities proprioceptive neuromuscular facilitation training with functional electrical stimulation had positive effects on the balance and gait of stroke patients.

  • Background & Object : The aim of this study was to investigate the usefulness of electrogastrography in the diagnosis field of traditional medicine through a study of the relationship between gastric motility and health condition based on oriental medicine diagnostic theory in functional dyspepsia. Method : 86 patients (male 27, female 59) with functional dyspepsia and 10 healthy control subjects (male 5, female 5) were involved in the investigation. The disease information of functional dyspepsia (based on Rome criteria II) was used for dyspeptic index and scores were obtained from the comprehensive diagnosis of Qui, Xue, Shui was applied as index for health condition, those were all investigated by questionnaire. Gastric motility were recorded and analyzed using electrogastrography in fasting and postprandial period. Results : The total score of comprehensive diagnosis of Qui Xue Shui was influenced by the number of functional dyspepsia symptoms (p=0.026). In terms of electrogastrographical parameters, both postpranial normal slow waves regularity(p=0.003) and power ratio (p=0.001) in the patients had the statistical significance and they showed an incremental inverse correlation with the number of symptoms. Dominant frequency and fasting normal slow waves regularity ratio had no statistical significance. Conclusion : Results suggest that electrogastrography is useful in evaluating the health condition of patient by comprehensive diagnosis of Qui Xue Sui.

  • Purpose : Selective functional movement assessment(SFMA) is a movement-based assessment tool designed for clinicians to diagnose and treat pain and functional physical problems. This concept is used for assistance in occupations related to movement, including clinical medical personnel, such as physical therapists, physical education instructors, and athlete coaches. Although this concept is widely used by clinicians, research and scientific proofs are relatively insufficient. This study aimed to review the literature on the understanding, reliability and effectiveness of SFMA, and to consider its role in the future of rehabilitation. Methods : In this review, a total of nine articles were selected according to the eligibility criteria of three major thesis topics. The main topics covered in the literature are reliability and effectiveness of clinical use of SFMA. To gather research articles, we searched official term 'Selective Functional Movement Assessment'. Among the searched 60 studies, nine were mentioned in this study that contained overlapping information and matched our desired topic. We reviewed four reliability analyses, four case reports, and one experimental study. Results : Reliability has an intermediate degree between high raters and within raters. The validity of the SFMA system is influenced by a combination of experience and logic; hence, further improvement is needed. Therefore, if the intervention was effective based on the diagnosis result, then biomechanical evidence is necessary to further support the claim. Conclusion : In future research, to use SFMA as a diagnostic tool with high accuracy, it is necessary to improve the reliability of the main problem through breakout, support for guidelines and validity and efficiency.
