A diverse range of products are currently being sold; however, it is very difficult to purchase All-in-One patterns that reflect the body types of the elderly stage in the open market. This study is to develop specialized All-in-One patterns by assessing obese body types characteristics of the elderly social class. Five healthy women with typical obese body types in the elderly stage with busts, waists, and hips surpassing 100 cm were chose as test subjects. The three subjects for the wearing experiment are those with more than one year of experience wearing a bodysuit. A self-evaluation was made three times by looking in the mirror. The data from this study was processed to find averages and deviations; in addition, and a t-test was performed using the SPSS 24 statistical software. A total of 13 body parts were measured prior to and while wearing the specialized All-in-One patterns. Significant results were obtained from all 12 items. All-in-One for research appears to have produced a high level of satisfaction for subjects. This study can provide basic data on elevating the levels of satisfaction of the consumers in their elderly stages with special body types that deviate from standard body types at the time of wearing garments as well as for inner-wear companies to graft this market as a high-value-added niche market.

This study was conducted to verify the current criteria and classification system used to determine specialized general hospitals status. In this study, we proposed a new classification system which Is simpler and more convenient than the current one. In the new classification system clinical procedure was chosen as the unit of analysis in order to reflect all the resource consumption and the complexities and degree of medical technologies in determining specialized general hospitals. We developed a statistical model and applied this model to 117 general hospitals which claim their national insurance through electronic data interchange(EDI). Analysis based on 984 clinical procedures and medical facilities' characteristic variable discriminated specialized general hospital in present without misclassification. It means that we can determine specialized general hospital's permission In new way without using the current complicated criteria. This study discriminated specialized general hospital by the new proposed model based on clinical procedures provided by each hospital. For clustering the same types of medical facilities using 984 clinical procedures, we executed multidimensional scale analysis and divided 117 hospitals into 4 groups by two axises : a variety of procedure and the Proportion of high technology Procedure. Therefore, we divided 117 hospitals into 4 groups and one of them was considered as specialized general hospital. In discriminating analysis, we abstracted proportion of 16 clinical procedures which effect on discriminating the specialized general hospital in statistical system also we identify discriminating function which include these variables. As a result, we identify 2 discriminating functions, one is for current discriminating system and the other two is for new discriminating system of specialized general hospital.

Purpose: The aim of this study was to compare with color reproducibility of the coating method and dipping method using a colour liquid. Methods: Two groups of square-shaped specimens ($10mm{\times}10mm$ in diameter, 1.5mm thickness) were prepared for analysis(n=15/group). The CM(Coating Method) group was fabricated as full zirconia specimens with the coating coloring method and Group DM(Dipping Method) was prepared as specimens of 0.7 mm-thick zirconia plate using the dipping coloring method and veneered with 0.8mm-thick porcelain. Color parameters were measured with ShadeEye $NCC^{(R)}$ spectrophotometer and color differences were calculated using the equation ${\Delta}E^*= \{({\Delta}L^*)^2+({\Delta}a^*)^2+({\Delta}b^*)^2\}^{1/2}$. Non-parametric statistical methods, the Mann-Whitney test, and the Kruskal-Wallis test were used to analyze the data. Type one error rate was set at 0.05. Results: Color difference values larger than 7 were observed between specimens with the coating method and the dipping method, which were detectable difference in a clinical setting. Conclusion: Cautious application of the coating coloring method in a clinical setting and further researches to standardize the coating method are needed.

Purpose: The purpose of the study was a quantitative evaluation of common errors in digital impression procedure using CEREC$^{(R)}$ AC system. Methods: Two-hundreds digital impression data comprising 174 inlays, 26 onlays by CEREC$^{(R)}$ AC in-office CAD/CAM system were obtained from a dental clinic. One evaluator assessed errors of the digital impression data and divided into five categories of errors: inappropriate scanner positioning (ISP), improper handling with a scanner (IHS), irregular powder arrangement (IPA), improper cavity preparation (ICP), and insufficient scanned data (ISD). Results: The most common errors were IPA(21%), and ISP and ISD were followed by 17% respectively. IHS was found in 14.5% of all digital impression data. ICP comprising only 6.5% was the rarest. Conclusion: Most errors were due to inaccurate manipulation with an intraoral scanner or improper cavity preparation for scanning. A deliberate manipulation to prevent common errors mentioned may deliver an optimal result in the digital impression procedure.

Health outcomes are strongly associated with dietary factors. Poor dietary intake increases health risks and can have adverse affects throughout all stages of live and can be passed onto next generations. Korea faces a double burden of nutritional problems. One one side health problems are related to an inadequate diet including underweight, osteoporosis or anemia etc. On the other side the health problems are related to over consumption, including obesity, hypertension, diabetes, cancer, cardiovascular disease and etc. Improving the national health and nutritional status requires adjustments of nutrition policies that have primarily focused on under nutrition, to accommodate all nutrition concerns within the country. Nutrition research specific to Korean people must be promoted to produce scientific evidences on which to base nutrition policies. The creation of a nutrition-specialized institute is an important starting point.

This research was performed to investigate the determination factors of medical service to cover the fee for selecting a doctor which is one of the most important causes of debilitating national health insurance in Korea. Data was from Korea Health Panel and analyzed by Dutton(1986)'s medical service model which was an extended Anderson Model and was widely used in the researches on determination factors of medical service. The results were as follows; In the determinants of selecting a doctor in specialized medical institutions and general hospitals, patients with serious diseases selected doctors more often than other patients. By industrial accident compensation insurance law and enforcement ordinances, insurance covers the fee of selecting a doctor in the hospitals appointed by Labor Welfare Corporation for the patients in critical conditions under industrial accident compensation insurance, while health insurance patients pay the fee themselves for selecting a doctor in all cases. It is suggested that patients with serious diseases proved by medical opinion be provided with health care insurance in selecting a doctor and that the health insurance benefit coverage be enhanced by staged lowering of patient's cost-sharing.

Purpose: Although endoscopic retrograde cholangiopancreatography (ERCP) has been used for more than five decades, its applicability in Bangladeshi children has recently become more common. Therefore, this manuscript aims to describe our experience in performing ERCPs in Bangladeshi children with hepatopancreaticobiliary diseases, focusing on presenting diseases, as well as the diagnostic and therapeutic efficacy. Methods: Between 2018 and 2021, 20 children underwent 30 ERCP procedures at the Bangladesh Specialized Hospital, Dhaka. A single trained adult gastroenterologist performed all procedures using a therapeutic video duodenoscope. The indications for ERCP, diagnostic findings, therapeutic procedures, and complications were documented. Results: The median age of the study patients was 10 years (range, 1.7-15 years). Successful cannulation of the papilla was achieved in 28 procedures and failed in 2 cases. Repeated ERCP was required in seven patients. Nine patients had biliary indications and 11 had pancreatic indications. Choledocholithiasis was the most common indication for ERCP in patients with biliary disease, while chronic pancreatitis was common among patients with pancreatic indications. Pancreatic divisum was observed in only one patient. Pancreatic and biliary sphincterotomy was performed in 14 and 9 cases, respectively. A single pigtail or straight therapeutic stent was inserted in seven cases and removed in five cases. Stone extraction was performed in six procedures, and balloon dilatation was performed in five procedures. The post-procedural period for these patients was uneventful. Conclusion: We found that ERCP is a practical and successful therapeutic intervention for treating hepatopancreaticobiliary disorders in children when performed by experienced endoscopists.
