  • It is well understood that liposarcoma is most common in soft tissue sarcomas. It usually develop proximally in the extremities and most patients are older than 50 years. We report a case of huge liposarcoma which develop on left thigh of 67-year-old man. There was no evidence of metastasis and the tumor was successfully removed by marginal resection. Patient's height is 153 cm and weight is 43 kg, but the tumor's size is $34{\times}20{\times}9\;cm$ and weight is 2.82 kg. The Mass is severely huge in compare with patient's height and weight. But, There are few reports regarding the correlation between tumor-size and pathologic differentiation. Pathological examination reveals a well differentiated liposarcoma. The patient is still asymptomatic at 6-months follow up.

  • Spindle cell lipoma is a relatively rare adipocytic neoplasm that is easily mistaken for a liposarcoma, and is histologically characterized by a mixture of uniform spindle cells and mature fat cells. It occurs predominantly in male patients aged $45\~65$ years, and in most cases it arises in the subcutaneous tissue of the neck or shoulder. We report a case of a 45-year-old woman with spindle cell lipoma arising from the left pleural cavity.

  • The effect of dietary fish oil ( mackerel oil : MO, eel oil : EO) on energy utilization in rats was studied with measurements of various tissue lipoprotein lipase( LPL ) and live and heart mitochondrial respiration. Fatty acid composition of mitrochondrial inner membrane matrix was also investigated. Dietary fat level was 10%( w/w) and reference groups were fed soybean oil (SO), repeseed oil ( RO) and beef tallow( BT ). Activity of LPL was about 60% higher in post-heparin plasma and 2 to 3 times higher in adipose tissue of BT group than fish oil or vegetable oil group. But there was no significant difference between fish oil and vegetable oil groups. Inclusion of EO above 2% (w/w) in dietary fat with fille oil of BT, markedly reduced both post -heparin plasma and adipose tissue LPL. Effects of MO and EO were not different in adipose tissue LPL, but EO was more effective than MO, in reducing post -heparin plasma LPL when mixed fat with varying amount of fish oil was used. Hepatic mitochondria isolated from fish oil-fed group showed the lowest rate of respiration but had P/O ratio comparable to SO and BT groups. On the other hand, cardiac mitochondria of fish oil group showed no difference in all the mitochondrial respiration parameters observed RO group had lowest P/O ratio both in hepatic and cardiac mitochondria. Fatty acid compositions of mitochondrial lipid differ between SO, RO, BT and MO groups, notably in the content of $C_{22:1}$ fatty acid.

  • The relocation policy of public Institutions throughout provincial areas that implemented for the purpose of "balanced national development" finished in 2019 with the last relocation of the Korea Institute of Science & Technology Evaluation and Planning, which moved to Chungbuk Innovation City. Electric power public corporations also completed relocation program over eight regions across the nation. This study was conducted empirically to identify the structural relationship between the public service motivation and job attitude. In this, the relationship of organizational change, particularly occurred by the regional relocation, with the psychological state of these organization members (experienced direct changes and got substantial impacts in various aspects such as psychological, economic and living environment, etc.,) was studied. This study aims to seek early organizational stabilization ideas for electric power public corporations after relocation, and to present some implications that can contribute to the secondary relocation of public institutions to local areas. This study shows the statistically significant relationship between the psychological state occurred by relocation and organizational commitment. The result shows that the higher the expectation levels, the higher the degree of organizational commitment, while anxious psychological state has no relation with that. Additionally, expectation level has no significant functional relation with turnover intention. Followings are the major conclusions revealed in this study; The stronger the anxious psychological state, the higher the turnover inducement goes up. The higher the expectation levels, the higher the public service motivation grows, and the higher the anxiety psychological state, the public service motivation lowers. The organizational commitment grows according to the public service motivation proportionally, but the turnover inducement intention is weak. The moderating effect of public service motivation between the expectation of organizational change and turnover intention was not significant, but it was analyzed that the moderating effect of public service motivation formed a significant relationship with other anxiety psychology. The expectation levels of employees of electric power public corporations has grown up after moving to provincial areas. Relationship between the expectation mind and the turnover inducement has decreased after local relocation.

  • The peroxisome proliferator-activated receptor $\gamma$(PPAR$\gamma$), a member of the steroid/thyroid nuclear hormone receptor suferfamily of ligand-activated transcription factor, is an important regulator of adipocyte gene expression and differentiation. In this studies, we report the identification, characterization, and expression of a Hanwoo PPAR$\gamma$ gene. The PPAR$\gamma$ cDNA sequence of the Hanwoo show strong conservation with the corresponding sequences reported in other species except of three amino acid sequences. The distribution of PPAR$\gamma$ mRNA in various tissues of Korean cattle aged 12 months were investigated using Northern Blot analysis. The highest expression was detected in adipose tissue, more lower expression was detected in colon, small intestine, kidney, lung, while expression was not detected in brain, heart. PPAR$\gamma$ expression was higher in adipose tissue of Korean cattle when aged 30 months than aged 12 months. These results indicated PPAR$\gamma$, regulator adipocyte gene expression and differentiation, related on adipose differentiation in Korean native cattle(HANWOO).

  • In this study, we investigated the inhibition of phyto-extract mixture (PEM) in several digestive enzymes ($\alpha$-amylase, $\alpha$-glucosidase and lipase) for anti-obesity. The current study also examined the effects of PEM on adiposity and serum lipid levels in obese mice fed with high fat diet. ICR male mice weighing $33{\pm}1.1\;g$ were randomly divided into three groups, one normal diet group (control, ND group) and two high fat diet groups with or without PEM supplement (HFD group and PEM group). The mice were fed the PEM experimental for 6 weeks and then they were sacrificed. The results showed that the final weight, weight gain, food efficiency ratio and body fat were decreased by the addition of PEM compared to those of HFD group. White adipose tissue weights of epididymal, mesenteric and retroperitoneal areas in the PEM group were reduced to 31.2%, 8.8%, and 37.8%, respectively, compared to the HFD group. The levels of serum triglyceride, total cholesterol, LDL-cholesterol in the PEM group were significantly lower than those of HFD group. The body weight gain and food efficiency ratio of PEM group were significantly lower compared with those of HFD group. From the above results, the PEM may be effective material for anti-obesity through reducing serum triglyceride and body fats as well as decreasing body weight.

  • To investigate whether genistein regulates menopause-induced obesity, it was studied the effects of genistein on anti-obesity effects in female ovariectomized (OVX) mice, an animal model of postmenopausal women. 7-week-old female mice (C57BL/6J) were randomly divided into three groups. All the animals received a high fat diet or a high fat diet supplemented with genistein for 8 weeks and variables and determinants of obesity were measured. The OVX mice had significantly higher body weight and adipose tissue mass than sham mice. However, genistein supplementation reduced body weight, adipose tissue mass, and adipocyte size of OVX mice. The OVX mice treated with genistein had significantly lower levels of serum triglycerides and total cholesterol than the vehicle-treated OVX mice. Lipid accumulation in liver was also markedly decreased by genistein in OVX mice. The results suggest that genistein can effectively prevent adiposity, adipocyte phertrophy, and llipid disorders caused by ovariectomy. Moreover, this study may contribute to the alleviation of metabolic syndrome, including obesity and hyerlipidemia in postmenopausal women.

  • The purpose of this research was to investigate the effects of 10%(w/w) of various dietary fiber, pectin(P), lignin(L), cellulose(C) and fiber-free (F) on lipid content of serum, liver and intestinal tissues in rats fed 10% coix oil (C)-or lard(L)-1% cholesterol diets for four weeks. The lard pectin(LP) group was the lowest In body weight gain and feed intake. Liver weight was not affected by dietary fiber and fat sources, and intestinal weight was higher in pectin(CP, LP) groups than in the other groups. Serum cholesterol was significantly lower in pectin(CP, LP) groups than in fiber-free(CF, LF) groups, and was higher in lard fiber-free(LF) than In the other groups(p<0.05). Serum triglycerides was significantly lower in coix oil pectin(CP) and lignin(CL, LL) than in fiber-free(CF, LF) groups. Liver total lipid and cholesterol content was significantly lower In pectin than In lard fiber-free group, and liver triglycerides was lower in coix oil pectin(CP) than in fiber-free groups (p<0.05). Lipid content of intestinal tissue was not affected by dietary fiber source. But total lipid and triglyceride content of intestinal tissues was significantly lower, and cholesterol content was higher in coix oil than in lard group(p<0.05). These results indicate that pectin and lignin reduced serum cholesterol. Pectin also decreased total lipid, cholesterol and triglyceride contents of liver in rats fed either coix oil-or lard-cholesterol diets whereas lignin did not affect liver lipid content.
