Gosan Yoon, Sundo's Gumswae-dong Garden Heritage has been designated as a National Historical Site 432 including Hyunsan old fortress wall. The site requires maintenance planning. For the plan, it also requires the consideration of Gosan's written documents describing the garden heritage and the site survey with on-site inspections for authentic maintenance approaches. It should be based on the thorough comprehension of historical remains. The site is a traditional ancient garden, so its approaches should be different with a historic structure and building. For the planning, the study conducts the interview of residents and experts, literature review, the investigation of historical materials, site survey, and the analysis of aerial photography. The results are following:5) Firstly, the paper suggests three types of an excavation area selection: core, recommend and investigation. Secondly, of 22 landscapes named by Gosan, it has the plan of guidance facilities, vegetation maintenance, safety facilities, landscape maintenance as view points, pathway maintenance, deck, and halting place. Thirdly, it also suggests pathway plan for authentic garden promenade according to the literature of Gumswaedong-Gi, an old map and aerial photography(1967, 1976, 1990), and interviews with residents. Fourthly, it suggests vegetation refurbishment at the site to check erection time and to require a preservation plan. In a case of no historic remains part, it also has a plan of amenities for visitors and wetlands for biodiversity of ecology and landscape. Finally, although it requires excavation and more historical evidences for the Hyunsan fortress wall, it suggests a maintenance plan of Pyeonchuksseong and Hyeopchuksseong partially.

The purpose of this study was to identify the landscape characteristics of Youngnam-Lu by performing text analysis of related Korean poems over 600 years. A total of 354 poems were quantitatively analyzed for keywords and terms in particular categories such as nature. As a subsidiary analysis, topographic map was examined using CAD along with analysis of antique maps. Of the 354 poems reviewed, keywords frequently used are: 'Scenic sites'- 56 times, 'Long river' (長江) and 'Long stretched forest'(長林) - 39 times each, 'Superb scenery'- 31 times, 'Large field scenery'- 19 times, and 'Thousand-layered mountain view' - 14 times. In total, these keywords occurred 159 times in 44.9 % of these poems.1) The words used frequently in these poems, especially for those fall under category of nature, can be scored into different subcategories such as natural phenomena and geographical features. Occurrences of terms in each subcategory were main criteria for the analysis and the following is a list of subcategories with frequency in descending order: Natural phenomena (44%), geographical features (33%), plants (14%), and animals (9%). Among natural phenomena, phenomena related to sky were most frequent, 41 times, which might be due to superb sky view from Youngnam-Lu. Also geographical features of Youngnam-Lu were reflected in these poems, and the most prominent features were 'flow of the river' and 'Sand island' located in the Milyang River. These poems contained fairly large number of terms related to musical instruments (8%) which suggest that Young-Nam-Lu as a place where various musical instruments performances were held.

In women, obesity rises with menopause. By comparing the dose-dopendent effects of genistein on regulation of body weight and lipid levels with swimming exercise in female ovariectomized (OVX) mice, an animal model of postmenopausal women, the effective dose of genistein on obesity control was investigated. Ovariectomized female mice were divided into control group, swimming exercise group and genistein concentration (0.005%, 0.05%, 0.1% wt/wt) treatment group and all mice fed high-fat diet for 8 weeks. The three different genistein doses as well as swimming decreased body weight, white adipose tissue mass, plasma lipid levels and lipid accumulation in liver, compared with control OVX mice. These decrease effectiveness of genistein showed dose-dependent manner, and is most effective at 0.1% genistein concentration, and paralleled effects of swimming on body weight, white adipose tissue, plasma lipid levels and lipid accumulation in liver. This present findings indicate that optimal dose of genistein in feamle OVX mice have a similar effect to swimming exercise on improvement of obesity. Intake of dietary genistein supplements will help obesity prevention in postmenopausal women.

This study was conducted to investigate the effects of ethanol extract from Lycii folium (L. folium) leaves on obesity index, serum lipids, homocysteine, leptin, ghrelin, and glucose in obese rats. Sprague-Dawley rats were administrated high-fat diets to induce obesity. Then, obese rats were divided into three diet groups: a basal-diet obese group (BO group), high-fat diet obese group (FO group), and high-fat diet plus L. folium extract obese group (FLEO group). Three groups were each fed experimental diet for 8 weeks. There were no significant differences in body weight and FER among the groups. However, obesity index such as Ro？hrer index, Lee index, and T.M. index of FLEO group was significantly decreased as compared to FO group. While serum triglyceride of BO group was significantly decreased as compared to FO group, there were no significant differences in serum lipids, homocysteine, leptin, ghrelin and glucose between FLEO group and FO group. In conclusion, these results indicated that ethanol extract from L. folium leaves might be beneficial with anti-obese effect by reduction of obesity indices in obese rats.

Diabetes Mellitus (DM) is well known for increasing morbidity and mortality, especially related to their complications. The purpose of this study was to investigate the factors affecting the prevalence rate of DM and provide a fundamental material to develop an intervention strategy to reduce the prevalence rate of DM. The study subjects were adults aged over 19 on the basis of the primitive data of "The Fifth Korean National Health and Nutrition Examination Survey, 2012". Therefore, the data of 5995 participants were analyzed. For data process, the complex sample analysis module of SPSS 18.0 program was employed to add weighting before analysis. According to the analysis, the prevalence rate of DM of the study subjects was 10.5%. Regarding the odds ratio of DM prevalence, the subjects who graduated from middle school had the odds ratio 2.51 times higher than those who graduated from college and more; those in subjective bad health condition 4.77 times higher than those in subjective good health condition; those in obesity 1.44 times higher; those with high blood pressure 2.57 times higher; those with hyperlipidemia 2.63 times higher; those who fail to control their weight 1.31 times higher; those going on a diet 2.75 times higher. This study revealed that a level of education, perceived health status, obesity, high blood pressure, hyperlipidemia, weight control, and dietary therapy were the predictable variables of the prevalence rate of DM, and thereby suggested the nursing direction and research direction to reduce the prevalence rate of DM.

This study was conducted to examine the effects of Cheonggukjang powder made using black foods on liver function and lipid composition in streptozotocin(STZ)-induced diabetic rats. The experimental animals were divided into 5 groups and fed the following for 7 weeks; normal diet(control), STZ+normal diet(Diabetic), STZ+50% soybean Cheonggukjang supplementation(DSC), STZ+44.5% yakkong Cheonggukjang supplementation(DYC), and STZ+supplementation with 50% yakkong black food(black rice, black sesame seeds, and sea tangle) Cheonggukjang(DYCB). The results showed that the body weight gain and food efficiency ratio of the STZ-induced diabetic groups were significantly lower than those of the control group. In the Diabetic group, glutamic oxaloacetic transaminase(GOT) and glutamic pyruvic transaminase(GPT) activities and total bilirubin content in serum were significantly greater than those in the control group. However, supplementation with Cheonggukjang reduced these values. In the Diabetic group, the triglyceride, total cholesterol, and low-density lipoprotein(LDL)-cholesterol contents in the serum and liver tissue, as well as the atherogenic index(AI) and cardiac risk factors(CRF) were significantly higher than the corresponding values in the control group, although the high-density lipoprotein(HDL)-cholesterol and phospholipid contents were significantly lower than those in the control group. However, supplementation with Cheonggukjang normalized the changed lipid composition in the STZ-induced diabetic rats. Further, yakkong Cheonggukjang and black food contaning yakkong Cheonggukjang normalized AI and CRF.

This study was designed to establish the effects of Zingiber mioga, Zingiber mioga root and Zingiber ofiicinale on the lipid concentrations in hyperlipidemic rats. A total of 24 male Sprague-Dawley rats weighing 60$\pm$5g were fed one of four experimental diets for 4 weeks: a control diet (hyperlipidemic diet), diets supplemented with 3% of Z. mioga, 3% Z. mioga roots or 3% Z. officinale. The concentration of total cholesterol in serum was significantly decreased by 31% in Z. mioga group compared to the control group. The HDL-cholesterol concentration was significantly higher in Z. mioga and Z. mioga root supplemented groups than in control group. Triglyceride concentration in serum and liver significantly decreased with 3% Zingiber supplemented groups compared with control group, but had no significant differences among three Zingiber supplemented groups. The contents of total cholesterol triglyceride free cholesterol and cholesteryl ester in liver were remarkably lower in Zingiber supplemented groups than in control group. However, hepatic phospholipid level was not showed significant effect.

This study was designed to examine effects of the various levels of sardine and safflower oil mix on lipid contents of serveral tissues in dietary hyperlipidemic rats. Experimental oils were 16% butter(control group), 8% butter +8% olive oil(group 2) 8% butter+8% sardine oil(group 3) 8% butter+6% sardine oil+2% safflower oil(group 4), 8% butter+4% sardine oil+4% safflower oil(group 5),8% butter+2% sardine oil+6% safflower oil(group 6) and 8% butter+8% safflower oil(group 7). The diet administered to the male rats of Sprague-Dawley were fed for 4 weeks. In livers, total cholesterol and triglyceride, phospholipid concentrations were lowest in the group 5 and free cholesterol concentrations were lower in the groups 4 and 5, particularly. Total cholesterol and triglyceride concentrations in brain were significantly lower in the group 5 and phospholipids were lowest in the group 3, while free cholesterol were group 7. In testes, total cholesterol and triglyceride, phospholipid, free cholesterol concentrations were lower in the all experimental groups than the control group, but those of kidney were lower in the groups 3, 7 than in the control group. Feeding mixed oil having equal quantity of sardine oil and safflower oil were effective on the reduction of the lipid contents in the principal tissues. It might be due to the effects of appropriate ratios of P/S, 0.85 and n-6/n3-p, 2.85 in the test lipids.

This study was designed to observe the effects of the feeding mixed with the sardine oil containing n-3 EPA, DHA and the safflower oil in which rich n-6 linoleic acid on the improvement of the lipids and on the fatty acid matabolism of serum lipoprotein in the dietary hyperlipidemic rats. Experimental oils mixed with 16% butter(control group) and 8% butter+8% olive oil, 8% butter and various level of sardine and safflower oils were administered to the male rats of the Sprague Dawley for 4 weeks. Concentrations of total cholesterol in serum lipoproteins were highest in the LDL, followed by VLDL, HDL and chylomicron components. in the triglyceride concentrations, chylomicron were highest, and much VLDL, LDL, HDL components. There were highest in the HDL, followed by LDL, VLDL and chylomicron in phospholipid concentrations of serum lipoproteins. Concentrations of total cholesterol, triglyceride and phospholipid in serum lipoprotein were lower in the other groups than in the control groups, and particularly, lowest in the group 5(4% sardine oil+4% safflower oil). From this results, the feeding equal quantity mixed oil with n-3 PUFA rich sardine oil and n-6 PUFA rich safflower oil were effective on the improvement of the lipid composition in the serum lipoprotein. It might be due to the effects of appropriate rations of P/S, 0.85 and n-6/n-3P, 2.85 in the test lipids. In the fatty acid composition of serum lipoprotein, ratio of P/S and n-3/n-6P were influenced from the fatty acid compositions of the mixed test lipids. And EPA contents were higher in the chylomicron components.

The present study was undertaken to determine the metabolic effect of various levels of fat in the diet. Forty males and the same number of females weighing $35{\pm}29$ were divided into three experimental groups and one control group, 10 rats each in both sexes. The dietary lipid contents were included in three levels, 2% as low, 30% as high and fat free diet in order to reflect the lipid consumption of present Korean diet. 20% sugar casein diet were employed as standard for control animals. This study was carried for 16 weeks. After these period animals were sacrificed to collect the internal organs and blood samples by heart puncture. In the result of this study, high fat diet group is lower than low fat diet group in the body weight gain, food efficiency ratio, protein efficiency ratio, urinary nitrogen and organ nitrogen contents were same trend but there is no significant difference in these respects. It was noteworty that high, and free fat diet group revealed more glucose total protein, albumin and globulin contents in the serum than other compared groups. It can be concluded that fat content whether low or high are free in the diet did not show significant effect on body nitrogen metabolism. But 30% high fat diet increased the total lipid and total cholesterol contents in the liver and the serum. This fact can be interpreted that 2% low fat diet and fat free diet do not need to increase the amount of fat content in the diet as high as 30% fat diet. This result might indicate the one possible reason to decide the recommanded dietary fat levels in Korean diet.
