Effects of the addition of single or blends of konjac flour (KF), carrageenan (CN), and soy protein isolate (SPI) into the sausage formulation were determined based on the physico-chemical and textural characteristics of low-fat comminuted sausage (LFS, fat <3%). LFSs had a pH range of 6.10 to 6.16, 77-79% moisture, <3% fat, and 13-15% protein contents, whereas regular-fat sausages (RFSs) had a pH value of 6.11, 62.5% moisture, 19.4% fat, and 11.9% protein. LFSs containing fat replacers were reduced (P<0.05) cooking loss (CL, %). KF alone or mixed with other hydrocolloids slightly improved the water-holding capacity, whereas CN increased (P<0.05) the gel strength, resulting in higher hardness values. Replacement of 6% lean meat with 1.5% SPI alone increased (P<0.05) yellowness (Hunter b value) and expressible moisture (EM, %). TPA values of KF+CN+SPI were the most similar to those of RFSs. These results indicated that triple addition of KF, CN and SPI at the ratio of 1 : 1 : 3 in LFS formulation improved functional properties, as compared to the low-fat control, and had textural characteristics most similar to those with RFSs.

In this study, we compared the clinical usefulness of SPAIR (Spectral Adiabatic Inversion Recovery) and STIR (Short TI Inversion Recovery) to evaluate the fat tissues precisely. The images of brain axial (n = 20), lumber spine sagittal (n = 20), hip joint coronal (n = 17) and knee joint (n = 25) were obtained by turbo spin echo T2 weighted method on 3T magnetic resonance image. The signal intensity (SI) values were measured using region of interest in fat, muscle tissue, and background noise. The inhomogeneity values were measured using the standard deviation (SD) value divided by the mean values. SD signifies the amount of error which is similar to the imaging heterogeneity. In brain axial images, the SPAIR showed more superior SI and inhomogeneity results than the STIR. In spine, hip and knee images, STIR showed more excellent SI results, but poor inhomogeneity than the SPAIR.

Spinal epidural lipomatosis, which causes symptomatic compression of neural elements, is a relatively uncommon disease. Although it has been reported frequently in association with the administration of exogenous steroids, a few cases of epidural lipomatosis with no association to exogenous steroids, have been reported. Idiopathic spinal epidural lipomatosis may be a separate disease from that induced by steroid. Here, the authors present two cases of symptomatic epidural lipomatosis with no history of steroid-dependent diseases and review the relevant literature.

This study was performed to investigate the effects of ramie (Boehmeria nivea) leaf powder on improvements in lipid metabolism in serum, liver and adipose tissue, and the anti-obesity effect in rats fed a high fat/high cholesterol diet for 4 weeks to induce a hyperlipidemic and obese model rat. Male Sprague-Dawley rats weighting 210 g were divided into four groups; a normal diet group (N), a high fat/high cholesterol diet group (HFC), a high fat/high cholesterol diet with 5% ramie leaf powder group (HFC-RL), and a high fat/high cholesterol diet with 10% ramie leaf powder group (HFC-RH). The body weight gain increased with a high fat/high cholesterol diet, but gradually decreased in the ramie leaf powder fed groups compared with the HFC group. The liver index in the HFC group was highest among the four groups, although the difference was not significant compared with the ramie leaf powder fed groups. The adipose tissues weight in the HFC group was heavier than that of the N group, whereas those of groups fed ramie leaf powder decreased gradually. Alkaline phosphatase activity was not different between the HFC groups, but serum alkaline aminotransferase and lactate dehydrogenase activities decreased significantly after ramie leaf powder feeding. Levels of serum triglyceride, total cholesterol, LDL-cholesterol, atherogenic index and cardiac risk factors tended to decrease in the ramie leaf powder fed groups compared with the HFC group, whereas serum HDL-cholesterol level decreased in the HFC group and markedly increased in the ramie leaf powder fed groups. Levels of triglyceride and total cholesterol in the liver were significantly lower in the ramie leaf powder fed groups than in the HFC group. Levels of triglyceride and total cholesterol in adipose tissues were also lower in the ramie leaves powder fed groups than in the HFC group. The activities of heparinreleasable lipoprotein lipase (LPL) and total-extractable LPL in adipose tissues increased in the HFC group compared to that of the N group, but those of the ramie leaf powder fed groups decreased significantly. These results suggest that ramie leaf powder may improve lipid metabolism in serum, liver and adipose tissue and potentially reduce lipid storage.

This study was carried out to investigate the effect of Yacon (Polymnia sonchifolia Poepp. & Endl.) powder on cholesterol-lowering and anti-obesity effects in rats fed a high fat-high cholesterol diet for 4 weeks to induce hyperlipidemic and obese rat model. Weight-matched male Sprague-Dawley rats were assigned to four groups according to dietary fat, cholesterol levels and Yacon powder levels. Experimental groups were normal diet group (N), high fat-high cholesterol diet group (HFC), high fat-high cholesterol diet with 5% Yacon powder group (HFC-PSL) and high fat-high cholesterol diet with 10% Yacon powder group (HFC-PSH). The body weight gain and FER were increased by a high fat-high cholesterol diet, but gradually decreased in the Yacon powder fed groups compared with the HFC group. Food intake was lower in HFC groups compared with N group. The liver and adipose tissue weights of HFC group were heavier than those of N group, whereas those of groups administered Yacon powder were gradually decreased. The serum ALT, AST, ALP and LDH activities elevated by a high fat-high cholesterol diet were significantly decreased by Yacon powder administration. Levels of serum total cholesterol, LDL-cholesterol, atherogenic index and cardiac risk factor showed a decreasing tendency in the Yacon powder fed groups compared with HFC group. The serum HDL-cholesterol level decreased in the HFC group and markedly increased in the Yacon powder fed groups. Levels of total cholesterol and triglyceride in liver and adipose tissues were lower in Yacon powder administered groups than those in HFC group. These results suggest that Yacon powder may improve lipid metabolism of serum, liver, and adipose tissue and potentially reduce lipid storage.

To follow the government policy on 'balanced development of county', the employees of public agencies to be relocated should get used to the new working and living environments such as changing their homes or living away from their family. This study aims to figure out the awareness of the employees of public agencies to be relocated on such organizational change with Person-Organization fit concept and then to find out the effect of positive or negative awareness on job attitude such as organizational commitment and turnover intention. It is expected that public service motivation, the intrinsic motivation for public employees, positively acts as a medium between the awareness of organizational change and job attitude, which this study confirms through an empirical analysis of the employees of electric power public enterprise to be relocated. This study proves that firstly the awareness on organizational change is not directly related to organizational commitment, however, it affects directly turnover intention and public service motivation as an immediate cause and secondly public service motivation has a positive correlation to organizational commitment but it doesn't affect turnover intention and lastly organizational commitment has a negative correlation to turnover intention. Besides, this study empirically finds out that public service motivation has mediating effect which is significantly affects the awareness of organizational change, organizational commitment and turnover intention, and organizational commitment has mediating effect between public service motivation and turnover intention as well.

Evaluation of the resected margins of the frozen section during breast-conserving surgery can determine the presence of cancer cells in a short time and have a significant impact on the scope of surgery and the prognosis of the patient. However, breast tissue is composed of adipose tissue, which affects the accuracy of the test. In this study, a new method was applied to the resected surface of the frozen section in which wiping the surface of the frozen section block with alcohol was expected to expose the parenchyma to the surface as the adipose tissue would melt momentarily. Indeed, of the total of 98 cases, 37 cases showed a better exposure ratio of the parenchyma in the improved frozen section test than in the previous frozen section test. Of the 37 cases with increased visibility of parenchymal sections obtained by this method, two cases of ductal carcinoma in situ (DCIS) were detected. Although there are limitations such as turnaround time (TAT), the diagnostic accuracy of histopathologic examination of the frozen section may improve through this method and may have a direct impact on patient safety, and should therefore be researched further.

This study attempted to find out the degree of agreement between ultrasound image findings along with analysis of attenuation index and scatter distribution index values within tissues through quantitative measurement analysis using liver ultrasound images. From August 2022 to October 2022, liver ultrasound was performed on 45 patients who were suspected of having fatty liver and who received a prescription for liver ultrasound. As a result of the study, as a result of analyzing the agreement between the ultrasound image findings and the tissue attenuation index, the Kappa value was 0.82 (p<0.05), showing a very high agreement between the two examination methods. In addition, as a result of the agreement analysis between the ultrasound image findings and the scatter distribution index in the tissue, the Kappa value was 0.642 (p<0.05), showing high agreement between the two examination methods. At the time of fat liver prediction, the use of liver ultrasound findings and quantitative ultrasonography techniques, such as intra-tissue attenuation index and intra-tissue scatter distribution index, may be helpful in determining the degree of progression of fatty liver patients.

This study was conducted to investigate the cholesterol lowering effect and weight reduction of autoclaved soy flour, cheonggulgang and doenjang, which are fermented using Bacillus subtilis DJI, in rats fed a high-fat/high-cholesterol diet. Male Sprague-Dawley rats weighing 250 g, were divided into five groups; a normal diet group (N), a high-fat/high-cholesterol diet group (HFC), a high-fat/high-cholesterol diet with 5% autoclaved soy flour group (HFC-S), a high-fat/high-cholesterol diet with 5% cheonggulgang group (HFC-CJ), and a high-fat/high-cholesterol diet with 5% deonjang group (HFC-DJ). The body weight gain and adipose tissues weights increased in rats fed a high-fat/high-cholesterol diet, but decreased significantly in rats fed autoclaved soy flour, cheonggulgang and doenjang, compared with the HFC group. Food intake was lower in the all HFC groups (HFC, HFC-S.HFC-CJ and HFC-DJ) than that of the N group, However, there was no differences in the food intake between HFC diet groups. Serum triglyceride level increased with a high-fat/high-cholesterol dietgroup whereas HFC-CJ and HFC-DJ groups were markedly decreased serum triglyceride levels compared with N group. Levels of serum total cholesterol and LDL-cholesterol, and level of total cholesterol in the liver were significantly lower in the HFC-S group, the HFC-CJ group and the HFC-DJ group than that of the HFC group, but exerted no significant change between the HFC groups on levels of total lipid and triglyceride in the liver. Fecal total lipid content increased in the HFC-CJ group and the HFC-DJ group than those of the HFC group and HFC-S group. The activities of heparin-releasable lipoprotein lipase (HR-LPL) and total-extractable LPL in adipose tissues decreased in the HFC-S group, the HFC-CJ group and the HFC-DJ group compared with the HFC group. These results suggest that dietary cheonggulgang and doenjang may exert cholesterol-lowering effect and prevent obesity.

Histological study of eel was carried out to determine the effect of drying on muscular tissue and fat movement. The results are as follows: (1) Changes of muscular tissue during drying may he divided into two stages early and late. In the early stage there was apparent dehydration of connective tissue while in the late stage muscle fibre dehydration appears to occur. (2) Movement of fat during drying depends upon division and contraction of the myocommata caused by inner structural changes. This phenomenon appeared to be more apparent in the late rather than the early drying stage.(3) After freeze-drying traces of ice crystals were detected around the muscle cells. These ice crystals remained even after rehydration. (4) When muscular tissue was heated the connective tissue melted while muscle fiber dehydrated and solidified.
