The objective of this study was to investigate the physicochemical characteristics and sensory evaluation of dacquoise made with sugar or sugar replacement (tagatose, erythritol). Sugar (S) was replaced with tagatose (T), and sugar powder was replaced with tagatose (TS), and erythritol (TE). S showed the highest sugar contents compared with TS and TE (p <0.05) but there were no significant differences with T. There were not significant differences in specific gravity and spread factor among the sweeteners. S and T tended to have higher loss factors than TS & TE. The more tagatose was increased, the more the redness value increased compared with S, and sucrose showed similar tendency for lightness (redness; TS > T > TE > S, lightness; S > T > TS > TE). TE showed good results for physical characteristics whereas T was better in the sensory test. The above results bear out that tagatose and erythritol both are suitable as alternative sweeteners for making dacquoise, but tagatose was better. Tagatose appeared to be a better replacement for sucrose in baking dacquoise, and dacquoise with 33% of the sugar replaced tagatose (T) could be suitable for use by diabetic and obese people. 95.1% tagatose (TS) maybe appropriate for diabetic patients. In conclusion, tagatose is a suitable sugar replacement for making dacquoise.

The purpose of this study was to compare dental health status of South Korean adults, according to the control protocol of glycated hemoglobin A1c (HbA1c). From the measurements of HbA1c levels of 4,991 individuals over the age of 19 who participated in the sixth Korea National Health and Nutrition Examination Survey, the following conclusions were obtained. Glycated hemoglobin was 7.2% in the HbA1c ${\geq}6.6$ diabetic group and 5.9% in women and 8.5% in men. The ratio in the glucose non-control group was higher in the older age group, the lower average monthly household income group, and the lower education level group. Both the tissue health index and functioning teeth index indices were slightly higher in both men and women in the glucose control group. The tissue health index was higher in the younger age group, in the higher average monthly household income group, and in the higher education level group. The missing teeth (MT) index was greater among women (3.775 pieces) than among men (2.317 pieces) in the glucose non-control group. Higher age correlated with a greater number of MT, while higher income and education levels correlated with a lower number of MT. In conclusion, we will continue to provide counseling and education on oral health problems, thereby widening the awareness of the importance of oral health care and providing a variety of media and education methods related to medical and oral health that can manage diabetic patients according to the level of HbA1c It should be developed.

EIS (Electro interstitial scan) is a non-invasive and simple method to find the physio-pathological information inferred by electric current response with respect to low direct current applied between remote sites of the body. Although a few EIS-based devices for diagnosing diabetes were commercialized, they were not successful in offering clinical validity nor in confirming diagnostic principle. In this study, we measured the voltage responses of diabetic patients and normal subjects with a commercialized EIS device to test the usefulness of EIS in screening diabetes. For this purpose, voltage was measured between pairs of electrodes contacted at both palm, both soles of the feet and left and right forehead above both eyes. After feature extraction of voltage signals, the AUC (area under the curve) between the two groups was calculated and we found that seven variables were appropriately shown above 60% of accuracy. In addition, we applied the k-NN (k-nearest neighbors) method and found that the accuracy of classification between the two groups reached the accuracy of 76.2%. This result implies that the voltage response analysis based on EIS has potential as a diabetics screening method.

Specific endometrial preparation should occur during periimplantation period. That is a progress of serial differentiation and is absolute in implantation of embryo and successful pregnancy. Remodeling of tissues shown during embryogenesis is regulated by various factors including extracellular matrix (ECM). Marked changes during pregnancy are including embryo migration, decidual response, and differentiation of placenta in placental animals including human. These changes to successful implantation in embryo and uterus have to prepare the competence for attachment of embryo and uterus, and invasion defense of uterus. During these changes, ECM dramatically changes for maintaining the uterine and embryonic functions. The major component of most connective tissue is collagens. It is very complex and hard to explore the mechanisms for ECM modulation. Recently using high throughput methodology, PCR-select cDNA subtraction method, microarray, many candidate genes have been identified. Steroid hormones have fundamental role in implantation and maintenance of pregnancy. Dermatopontin, a regulator of collagen accumulation, is regulated spatio-temporally in the uterus by primarily progesterone through progesterone receptors at the time of implantation. Modulation of extracellular matrix is critically regulated by cascade of gene net-works which are regulated by cascade of sex steroid hormones. Pathological regulation of uterine extracellular matrix reported in diabetic patients. To know the extracellular modulation is essential to understanding implantation, feto-placental development and overcome the paths involved in female reproduction. Though ECM composed with very various components and it is complex, the present review focused on the fate of collagens during periimplantation period.

Rosiglitazone maleate (RGM) is widely used for improving insulin resistance. RGM is a moderate inhibitor of cytochrome P450 2C8 (CYP2C8) and is also mainly metabolized by CYP2C8. The aim of this study was to determine whether the effect of RGM on CYP2C8 is altered by co-treatment with other drugs, and whether amlodipine camsylate (AC) changes the pharmacokinetics (PK) of RGM. Of the 11 drugs that are likely to be co-administered with RGM in diabetic patients, seven drugs lowered the $IC_{50}$ value of RGM on CYP2C8 by more than 80%. In vitro CYP2C8 inhibitory assays of RGM in combination with drugs of interest showed that the $IC_{50}$ of RGM was decreased by 98.9% by AC. In a pharmacokinetic study, Sprague-Dawley (SD) rats were orally administered 1 mg/kg of RGM following by single or 10-consecutive daily administrations of 1.5 mg/kg/day of AC. No significant changes in the pharmacokinetic parameters of RGM were observed after a single administration of AC, but the AUC and $C_{max}$ values of RGM were significantly reduced by 36% and 31%, respectively, by multiple administrations of AC. In conclusion, RGM was found to be affected by AC by in vitro CYP2C8 inhibition testing, and multiple dosing of AC appreciably changed the pharmacokinetics of RGM. These findings suggest that a drug interaction exists between AC and RGM.

Previously, studies on compensation material to increase the signal intensity have been conducted which does not affect the reading of images. However, the compensation material has a concern on patient infection as it is attached directly on the skin. Therefore, in this study, we tested an indirect attachment of the compensation material as an alternative method of the direct attachment. The silicon compensation material was fabricated in the form of a cylindrical bar and attached to each element of the 8 channel head coil. Then the signal intensities of the water phantom pre and post application of the silicon were measured. T1 and T2-weighted images were acquired using an 8-channel head coil and a 3.0T superconducting MRI. Signal intensities were measured by using an image measuring program. Paired t-test was used to verify if there were significant differences. The signal intensity before application of the silicon was significantly increased by 3.39% and 2.62% in T1 and T2 weighted images, respectively. Although the indirect attachment method had a limitation to completely replace the existing method, it was considered to be useful in patients with infectious diseases such as diabetic complications since it had a meaningful improvement in signal intensity based on the filling factor increase.

This study was a pilot test of serious educational game content(named Roly Poly 160) designed to enhance self-care by elderly diabetics. Roly Poly 160 was developed in eight steps (literature review, demand survey and consultation, extraction of serious content using games, development of Roly Poly 160, pretest for users, workshop for health care workers, final completion of Roly Poly 160 and user satisfaction survey of Roly Poly 160). Roly Poly 160 is intuitively structured in three modules (self-management, card games, and quiz games) that can be self-managed by the elderly and is designed based on six principles. First, we constructed an intuitive interface considering the age of users. Second, the menu was selected as the main menu for Koreans and calorie learning was made at the same time. Third, the calories and nutrients (carbohydrate, fat, protein, calcium, sodium) of selected foods are analyzed, and all test data recorded in the questionnaire chart are graphically displayed by year, month and week so that the change trends can be grasped at a glance. Fourth, necessary data were saved and output and used as educational data. Fifth, user data are made compatible and aggregated and up to 100 million members can be registered. Sixth, it is designed to be developed as a mobile app if necessary. Using Roly Poly 160, 119 diabetic patients were diagnosed with diabetes, and the satisfaction score was 4.26 out of 5. These findings indicate that Roly Poly 160 is appropriate as a diabetes self-care tool and suggests that there is a possibility to use it as a program to educate people about diabetes in public health centers, hospitals and clinics.

In modern society, awareness of diabetes is growing with an increase in the elderly population and an increase in the incidence of diabetes. In particular, diabetic patients can suddenly develop hypoglycemic shock; therefore, it is important to measure blood glucose periodically. However, self-monitoring blood glucose meters are difficult to carry and it is difficult to manage the value. To solve these problems, the blood glucose measurement system has been developed as a sensor attached to the body or as one of the functions of smart devices, but it has not been commercialized. In this paper, we propose a smart band with a blood glucose measurement function. If a user enters a schedule to measure blood glucose level, such as before/after meals, in the app, he/she can receive a measurement alarm from the band. The user can measure the blood glucose level at any time using the band, and the measured value is transmitted and managed by the app including behavior history such as before/after meals and the time. This will help the user to manage, diagnose and prevent health problems. The system has been tested using two medical device-certified products, and each blood glucose measurement value has been confirmed to be more accurate.

[ ${\alpha}-Glycosidase$ ] inhibitors slows the velocity of the uptake of monosaccharides in the small intestine by retarding the speed of degradation of disaccharides to monosaccharides, which made it possible to develop ${\alpha}-glycosidase$ inhibitors as the antihyperglycemic ('antihyperglycemic' means 'blood-glucose-level-lowering') reagent for the diabetic patients such as acarbose and miglitol. Twenty kinds of ${\alpha}-glycosidase$ inhibitors have been reported to exist in mulberry, Morns alba, and some of them are also found in the silkworm, Bombyx mari, as the result of its daily feeding of mulberry leaves as the sole diet. 1-Deoxynojirimycin (DNJ), one of the most potent ${\alpha}-glycosidase$ inhibitor, is the most abundant among polyhydroxylated alkaloids with ${\alpha}-glycosidase$ inhibiting activity in both M alba and B. mari, therefore considered the antihyperglycemic criterion of the mulberry- or silkworm-based neutroceutical products. DNJ is thought to be accumulated in the body of silkworm because the its concentration in the silkworm body is two to three times as much as that in the mulberry leaves. Eighteen silkworm F1 varieties have been recommended for industrial rearing in Korea by some standards such as pathological strength. DNJ concentration in 18 recommendedwere measured at 3rd day in the 5th instar after lyophilization to determine the varieties that accumulates DNJ in its body most. GeumOk-Jam was the highest in the DNJ concentration of 5.45 mg/gDW among the recommended F1 varieties.
