A tape feeder is an important feeding device to supply micro-chips such as 1005 and 0603 components to PCB in SMT process. Traditionally, tape feeding methods using sprocket wheel mechanism has been used for the pickup system of chip-mounters. However, there is growing needs for new feeding mechanism with high accuracy and confidence as electric components are getting much smaller. Thus, recently, a tape feeder using cam-slider mechanism is developed to meet such requirements. The major advantages of developed system are; significantly reduced indexing and backlash errors, slim and compact design, and improved repetitive capacity compared to existing system. In this paper, the performance evaluation criteria for the developed tape feeder are suggested. Stability against induced vibration, positioning accuracy, cycle time, durability and supply error rate are estimated using developed self testers. As a result, the excellence of developed tape feeding mechanism is validated using the effective rating methods.

Purpose : The aim of this study was to investigate objective evaluation of dysmenorrhea. Methods : The study was conducted by 37 articles from year 1979 to 2003 on dysmenorrhea, scale and questionaire. The articles was limited by English, Human, and Clinical trial Results : 1. The 37 articles on dysmenorrhea evaluated by scale or questionaire have been published from 1979. There are 27 articles of randomized controlled trial among them. 2. Scale or question has confidence in the assessment of dysmenorrhea. 3. In the initial stage the article on dysmenorrhea was assessed by only one unidimentional scale. However in recent articles multidimensional scales are applied frequently. Moreover it is the modern trend that point scale such as 100mm VAS and MVRS(multidimensional verbal rating scale) are applied together in one article on dysmenorrhea. Conclusion : It can be suggested that scale or questionaire be the method for objective evaluation of dysmenorrhea.

Purpose : To evaluate and compare the efficacy of digital radiographic images in the detection of bone loss at the bifurcation area of the mandibular first molar with traditional film-based periapical radiographs, Materials and Methods : One dried human mandible with minimal periodontal bone loss around the first molar was selected and an artificial alveolar bone defect at the bifurcation area was serially prepared over 18 steps. Images were taken using a direct CCD-based system and with F-speed periapical films. The images were evaluated by seven interpreters (3 radiologists, 3 periodontologists, and 1 general dentist) using a 5-point confidence rating scale. Results : The readability of both periapical radiographs and digital image increased as the size of the artificial lesion and exposure time increased (p < 0.05). Periapical radiographs offered greater readability of smaller bone defects than digital images, and the coefficient of variation of mean score between periapical radiographs and digital images showed a significant difference. Conclusion : The experimental results indicate that a significant difference in the coefficient of variation of mean score exists between periapical radiographs and digital images, and that traditional film-based periapical images offer greater readability of smaller bone defects than digital images can presently offer.

Purpose : To compare the diagnostic accuracy of proximal caries detection between Kodak Insight film and the Biomedisys CDX2000HQ digital (CCD) sensor. Materials and Methods: 156 proximal surfaces of extracted teeth, 78 of which had chemical artificial caries, were used in this study. Four observers interpreted the radiographs using a five-point confidence rating scale to record their diagnoses. The results were analyzed by receiver operating characteristic curves, ANOVA and Kappa values. Result: Analysis using receiver operating characteristic curves revealed the areas under each curve which indicated a diagnostic accuracy of 0.951 in Insight and 0.952 in CDX2000HQ digital sensor. ANOVA revealed no significant differences between the two images with respect to caries detection. Kappa values indicated that the mean intra-observer agreement was 0.85 and inter-observer agreement 0.71 in conventional radiography. In digital radiography, the mean intra-observer agreement was 0.84 and inter-observer agreement 0.72. Conclusion: The results suggest that no significant difference exists between the two modalities for artificial caries detection and that CDX2000HQ was as good as Insight film for this purpose.

The study attempted to explore the dimensionality of mother's psychological well-being. The major purpose of the study was aimed at establishing the construct validity regarding the instrument of assessing mother's psychological well-being. Instrument for assessing psychological well-being was developed with 9 variables(sense of control, sense of achievement, sense of confidence, sense of acceptance, sense of intimacy, sense of assistance, sense of immersion, sense of hope, and sense of satisfacion) in 3 dimensions(sense of competency, sense of relation, and sense of improvement) with 4 rating scales of 102 items. After the scale development, the estimates of reliability for the 9-variable scales were Cronbach's ${\alpha}=.71{\sim}.90.$ The correlation between the two scales, Psychological Well-Being Index(Franklin, 1996) and Psychological Well-Being(Ryff & Keyes, 1995) was .21~25. The subjects were divided two groups by the score of the Mother's sense of Psychological Well-Being. And the group has hiher score in Mother's sense of Psychological Well-Being showed the higer score of Perceptions of Parental Role Responsibilities Scale(t=3.24, p=.002).

This research has the purposes of analyzing and proving empirically, such as: To investigate the effect of good corporate governance (GCG) on financial performance at banks in Indonesia through the mediating role of corporate asset growth. Theoretically, the study's results were expected to enrich and complete the repertoire of understanding in the financial management area, specifically with those phenomena related to banking financial performance and factors which influenced it. The population of this research was a bank that had a Corporate Governance Perception Index (CGPI) rating from 2011 to 2020. The type of sampling used was saturated sampling; thus, the whole population is sample members. Current data analysis used SEM. GCG has a direct or indirect impact on banking financial performance, according to the findings of this study. Improved GCG results in increased public confidence, which is reflected in an increase in total assets, as well as improved banks' financial performance. As a result, it can be stated that corporate asset increase largely mitigated the impact of GCG on bank financial performance in Indonesia. Through this rapid growth from corporate assets, Bank can maximize the market expansion which is ultimately able to improve banking financial performance.

This study developed low-cost and high-efficiency pavement condition monitoring technology to produce the key information required for pavement management. A noise and artificial intelligence-based monitoring system was devised to compensate for the shortcomings of existing high-end equipment that relies on visual information and high-end sensors. From idea establishment to system development, functional definition, information flow, architecture design, and finally, on-site field evaluations were carried out. As a result, confidence in the high level of artificial intelligence evaluation was secured. In addition, hardware and software elements and well-organized guidelines on system utilization were developed. The on-site evaluation process confirmed that non-experts could easily and quickly investigate and visualized the data. The evaluation results could support the management works of road managers. Furthermore, it could improve the completeness of the technologies, such as prior discriminating techniques for external conditions that are not considered in AI learning, system simplification, and variable speed response techniques. This paper presents a new paradigm for pavement monitoring technology that has lasted since the 1960s.
