The forward and afterward parts of ships and offshore structures are designed to improve the fuel consumption performance. These are made of curved plates with a large thickness. If a fabricated curved plate has some dimensional errors, a lot of additional cost is incurred in the assembly process. Thus, an accurate dimensional assessment is very important for fabrication. In this paper, we propose an assessment method for the dimensional quality management of curved plates. This can be applied to data measured using a variety of three-dimensional instruments, with boundary measurement points automatically classified and sorted to create a measurement surface. The assessment is evaluated after matching the CAD surface and the measured surface considering constrained conditions. The fabrication assessment is evaluated as a probability of how much the tolerance is satisfied.

Purpose: The purpose of this study was to analyze the factors associated with long-term hospitalized patients in long-term care hospitals using the quality assessment data for long-term care hospitals by the Health Insurance Review. Methods: Among 1,376 long-term care hospitals, frequency analysis and descriptive statistics were used to analyze the characteristics of these hospitals. Multiple linear regression was conducted to examine the associations between infrastructure characteristics, medical personnel characteristics, health outcomes and the proportion of long-term hospitalized patients. Results: The research findings indicate that the number of patients per doctor, the number of patients per nurse, and the number of patients per nursing staff were positively associated with the proportion of long-term hospitalized patients. Among health outcomes, a higher proportion of patients with more than a 5% weight loss compared to the previous month and the proportion of patients showing improvement in ADL, were more likely to have a lower proportion of long-term hospitalized patients. However the proportion of diabetic patients with HbA1c test results within the appropriate range was positively associated with the proportion of long-term hospitalized patients. Conclusion: The present study results provide fundamental data for the establishment of policies for long-term care hospitals. Based on this study, it is important to suggest screening methods for unnecessary long-term hospitalizations, such as sufficient medical personnel to improve the quality of care in long-term care hospitals. It is also necessary to clearly separate the roles of medical institutions and long-term care facilities and implement policies to support patients' social reintegration.

Purpose: The purpose of this study was to compare obesity-related quality of life according to obesity classification by BMI (body mass index) and self-assessment. Methods: The participants were 286 female college students in J City. Data were obtained by measuring height. weight and BMI, and using a questionnaire for self-assessment of obesity, weight control, and quality of life. The quality of life was measured using 14 items of the Korean version of obesity-related quality of life (KOQOL). Results: Thirty five percent of the students assessed themselves as overweight and obese despite their BMI <$23m^2/kg$(false overweight). True overweight students with BMI $\geq23m^2/kg$ who perceived themselves as overweight and obese were 23%. The total KOQOL score between true and false overweight students showed no significant difference. True overweight students had a lower total KOQOL score including psychosocial, physical, daily living, sex related. and food-related domains than true normal weight students. Conclusions: The quality of life was not different between true and false overweight students. These results indicate that self-assessment about obesity affects the quality of life like as actual BMI in female college students. Therefore, it is necessary to care students who distort themselves as obese.

Assessment of seasonal changes in surface water quality is an important aspect for evaluating temporal variations of river pollution due to natural or anthropogenic inputs of point and non-point sources. In this study, surface water quality data for 15 physico-chemical parameters collected from 7 monitoring stations in a river during the years from 2014 to 2016 were analyzed. The principal component analysis technique was employed to evaluate the seasonal correlations of water quality parameters, while the principal factor analysis technique was used to extract the parameters that are most important in assessing seasonal variations of river water quality. Analysis shows that a parameter that is most important in contributing to water quality variation for one season may not be important for another season except alkalinity, which is always the most important parameters in contributing to water quality variations for all three seasons.

Often arrangement for effective product assessment and audit have not been completely satisfactory. The underlying reasons are: (a) The lack of early evidence of new unit quality. (b) The collection and processing of data. (c) Ineffective data analysis techniques. (d) The variability of information on which decision making is based. Because of the nature of the product the essential outputs from an affective QA organization would be: (a) Confirmation of new unit quality. (b) Detection of failures which are either epidemic or slowly degradatory. (c) Identification of failure cases. (d) Provision of management information at the right time to effect the necessary corrective action. The heart of an effective QA scheme is the acquisition and processing of data. With the advent of data processing for quality monitoring becomes feasible in an automotive testing environment. This paper shows how the method enables us to use Automotive Testing data for the cost benefits of QA management.

Objectives: To determine the factors affecting the assessment of Oriental medical institutions under the Oriental Medical Institution Assessment System and thereupon, provide for some basic data and alternative measures for assessment of Oriental medical institutions. Methods: The researcher sampled 320 people employed by 26 Oriental medical institutions designated as model Oriental medical institutions subject to assessment in 2008 and 2009 and thereupon, used a structured and open-ended survey table for them to collect the data. The size of the final sample was n=302. Results: The Oriental medical institution staff were highly aware of the Oriental medical institution assessment (OMIA), After adjusting the other factors by multiple regression, the factors affecting such recognition were different significantly depending on age (those in their 30's), types of job (nurses and treatment assistants) and locations of hospital (GyeongSang-do). The staff expected the OMIA could helpful for improving facilities and system of hospitals, thus promoting satisfaction of patients. To do so, they felt it necessary to develop an assessment scale reflecting the special conditions besetting the Oriental medical institutions as well as the indices for improvement of Oriental medical service quality. Conclusion: It is hoped that this study will be followed up by future studies which will comparatively analyze Oriental medical institution staff's perception of the assessment system before and after its operation and thereby, suggest some ideal policy alternatives for assessment of the Oriental medical institutions. Furthermore, future studies are requested to research into Oriental medical institution staff's needs and consumers' needs as well in consideration of the characteristics of the Oriental medical institutions and thereupon, suggest some alternatives for continued education, development of the assessment tools, methods and policies.

Dental implant has recently become one of the most viable treatment options for regaining the oral function and dental aesthetics compared with conventional fixed or removable dentures. Dental implants vary in material, dimensions, geometries, surface properties, and interface geometries. It has been reported that there has been a proliferation of manufacturers who produce implants using various materials and surface treatments, and the dentist needs to select from over 2,000 different dental implants and abutments in a specific treatment situation. Unfortunately, however, no metrics have been specifically identified for the purpose of quality assessment and selection of an appropriate dental implant. This study aims to provide practical guidelines for quality assessment of dental implant based on clinical data. Like other medical devices and materials, the superiority related to specific characteristics of the dental implant needs to be verified through extensive clinical studies. The procedures of clinical monitoring for dental implants have been proposed along with a case study to exemplify the usefulness of clinical monitoring for the purpose of continuous quality improvement in medical industry.

Spatial prediction methods have been useful to determine the variability of water quality in space and time due to difficulties in collecting spatial data across extensive spaces such as watershed. This study compares two kriging methods in predicting BOD concentration on the unmonitored sites in the Geum River Watershed and to assess its predictive performance by leave-one-out cross validation. This study has shown that cokriging method can make better predictions of BOD concentration than ordinary kriging method across the Geum River Watershed. Challenges for the application of cokriging on the spatial prediction of surface water quality involve the comparison of network-distance-based relationship and euclidean-distance-based relationship for the improvement in the predictive performance.

Despite the widespread use, critics claim that citation analysis has serious limitations in evaluating the research performance of scholars. First, conventional citation analysis methods yield one-dimensional and sometimes misleading evaluation as a result of not taking into account differences in citation quality, not filtering out citation noise such as self-citations, and not considering non-numeric aspects of citations such as language, culture, and time. Second, the citation database coverage of today is disjoint and incomplete, which can result in conflicting quality assessment outcomes across different data sources. This paper discuss the findings from a citation analysis study that measured the impact of scholarly publications based on the data mined from Web of Science, Scopus, and Google Scholar, and briefly describes a work-in-progress prototype system called CiteSearch, which is designed to overcome the weaknesses of existing citation analysis methods with a robust citation-based quality assessment approach.
