비만한 중년 남성에서 열량제한과 운동을 통한 체중 감소의 효과
박현영,장양수,김오연,유하정,채지숙,이종호 대한비만학회 1999 The Korean journal of obesity Vol.8 No.2
$quot;Background: With abdominal obesity being recognized as an important risk factor of metabolic disease and atherosclerosis, it is important to determine the optimal weight loss program for decreasing this risk. The goal of this study was to determine beneficial health effects of modest weight loss with low calorie diet and exercise in middle-aged overweight Korean men. Method: Sixteen overweight men aged 40-49 years participated in a 3-month weight- management program. The diet and exercise program reduced daily energy intake by 300-400 kcal from daily energy need and expended about 100 kcal in walking and other light exercise. Compliance with the diet and exercise protocol was monitored through 7-day records of diet and physical activity maintained by subjects monthly. Adipose tissue and muscle areas were calculated from computerized tomography scans at 3 body levels, Ll, IA and mid portion of thigh before and after weight loss. Anthropometries, serum levels of lipids and hormones and response areas of glucose, C-peptide, insulin and free fatty acid during oral glucose tolerance test (OGTT) were determined. Result: After 3 months of diet and exercise, body weight fell an average of 4.9 kg (6.3%) and waist circumference reduced an average of Scm. Modest weight loss appeared to decrease blood pressure in overweight males. Although weight loss did not show any significant differences in thigh muscle and femoral subcutaneous fat areas, there was about 20% reduction in visceral, subcutaneous and total fat areas of Ll and L4 levels after weight loss. Mean values of serum total cholesterol, even though within normal range before weight loss, decreased significantly after weight loss. Serum triglyceride concentration fell from 192 to 143 mg/dL in association the loss of weight. Modest weight loss showed a 30% decrease in fasting insulin and response areas of insulin during OGTT. There was a 16% but not significant decrease in the response area of free fatty acid during OGTT after weight reduction. Conclusion: The result suggests that modest weight reduction with diet and exercise can show a rapid decrease in abdominal fat without muscle loss, compared with in femoral fat. Modest weight loss about 6% of initial weight can be viable apprach to help decrease serum lipids and hyperinsulinemia and improve insulin responsiveness to glucose challenge.
A Study on the Status of Waterbirds by Taxon and Seasonal Arrival in the South-West Coast Islands
박현영,김선집 국제문화기술진흥원 2023 International Journal of Advanced Culture Technolo Vol.11 No.1
This study surveyed the island located in Sinan-gun and Wando-gun four times, once per season from September 2020 to November 2021 in order to understand the distribution of waterbirds on the island of the southwest coast. As a result of the investigation, a total of waterbirds of 7 orders, 12 families of 50 species, and 3,680 individuals were identified. By taxon, the largest number of species were identified as 11 species of waders, and the number of ducks was the largest with 2,035 individuals. In Bigeum-do Island, where forests are distributed less, the proportion of farmland is large, and tidal flats are widely distributed, the largest number of species and individuals of herons and waders were identified. Ducks and gulls have also been identified in large numbers of individuals in Bigeum-do Island. Most of them are forests and farmland, and the largest number of species and individuals of ducks have been identified in Pyeongil-do Island, where the coast is deep. In addition, Nodae-do Island, Sobyeongpung-do, and Daebyeongpung-do Island with monotonous habitats have been identified with fewer species and individuals. As a result, We learned that various types of waterbirds lived in islands with various habitats, and that the preferred habitat was different depending on the characteristics of the taxon group. By season, the largest number of species was identified as 35 in autumn, and the largest number of individuals was identified as 1,681 in winter. Although most of the seasonally identified waterbirds were winter birds, the largest number of species were identified in autumn, and most of the confirmed waterbird migration were identified in the autumn, indicating that waterbirds used the west-south coast islands as an intermediate stopover while traveling.
Awareness and Understanding of Dementia in Community-Dwelling Adults Without Dementia and Stroke
박현영,김영서,박형종,이학승,석승한 대한노인병학회 2016 Annals of geriatric medicine and research Vol.20 No.4
Background: Early diagnosis and treatment of dementia has become a critical medical issue; however, knowledge and understanding of dementia in the general population remains insufficient. Accurately determining and increasing the level of knowledge of dementia will help improve dementia treatment and prevention. Methods: Using a questionnaire, we examined the degree of interest in dementia, comprehension of dementia, and level of knowledge of dementia among 716 middle-aged and elderly individuals without a history of stroke or dementia. We conducted an analysis of these associations with risk factors of dementia. Results: Most participants had an interest in dementia (93.3%) and a comprehension of dementia (91.1%). An analysis of the association between the level of knowledge of dementia, according to the characteristics of the participants and each variable, showed that higher education level, presence of a spouse, and higher level of interest in dementia exhibited a statistically significant positive correlation. Conclusion: This study shows that the level of knowledge about dementia in the community is relatively high for those participants who have a high interest in dementia or higher education level. To increase awareness of dementia and reduce dementia-associated socioeconomic costs, educational activities could be tailored to fit the level of education or interest in dementia of individuals, as an effective intervention for community-dwelling healthy adults.
Evaluation of gallbladder and common bile duct size and appearance by computed tomography in dogs
박현영,Yu-gyeong Cho,이영원,최호정 대한수의학회 2018 Journal of Veterinary Science Vol.19 No.5
The feasibility of using computed tomography (CT) to identify the common bile duct (CBD) and comparison with ultrasonography (US) results were evaluated in normal beagle dogs and dogs without hepatobiliary and pancreatic diseases. In addition, CBD diameters were obtained from CT at the level of the porta hepatis and the duodenal papilla level in dogs with underlying diseases that may cause cholestasis. US is a useful modality in the estimation of gallbladder volume because ejection fraction and CBD diameter from US were not significantly different from those of CT. The normal biliary tract was visible on CT images in 68% of the normal dog group. CBD diameter was not over 3 mm and 3.5 mm at the porta hepatis and duodenal papilla levels, respectively in normal dogs weighing less than 15 kg. Dogs suspected to have cholestasis associated with hepatobiliary or pancreatic diseases had significantly larger CBD than that in normal dogs.
