Obesity Phenotype and Coronary Heart Disease Risk as Estimated by the Framingham Risk Score

박용순,김준수 대한의학회 2012 Journal of Korean medical science Vol.27 No.3

There are conflicting data as to whether general or abdominal obesity is a better predictor of cardiovascular risk. This cross-sectional study involved 4,573 subjects aged 30 to 74 yr who participated in the Fourth Korea National Health and Nutrition Examination Survey conducted in 2008. Obesity phenotype was classified by means of body mass index (BMI) and waist circumference (WC), and participants were categorized into 4 groups. Individuals’ 10-yr risk of coronary heart diseases (CHD) was determined from the Framingham risk score. Subjects with obese WC had a higher proportion of high risk for CHD compared to the normal WC group, irrespective of BMI level. Relative to subjects with normal BMI/normal WC, the adjusted odds ratios (ORs) of normal BMI/obese WC group (OR 2.93 [1.70, 5.04] and OR 3.10 [1.49, 6.46]) for CHD risk in male were higher than obese BMI/obese WC group (OR 1.91 [1.40, 2.61] and OR 1.70 [1.16, 2.47]), whereas the adjusted ORs of obese BMI/obese WC group (OR 1.94 [1.24, 3.04] and OR 3.92 [1.75, 8.78]) were higher than the others in female. Subjects with obese BMI/normal WC were not significantly associated with 10-yr CHD risk in men (P = 0.449 and P = 0.067) and women (P = 0.702 and P = 0.658). WC is associated with increased CHD risk regardless of the level of BMI. Men with normal BMI and obese WC tend to be associated with CHD risk than those with obese BMI and obese WC.

Rural theme park is an on-going business that has been practiced by Ministry for Food, Agriculture,Forestry and Fisheries since 2007. The business aimed to facilitate urban and rural interchange and local economy activation. Rural theme park themed communities by using unique natural and cultural properties owned by the locals. the project adopts bottom-up development that reflects opinions of residents in the tourism planning process. However, it seems to be true that residents have been excluded from tourism planning process even if they were the host of the project for the reasons of lack of knowledge on community-based rural tourism development and lack of experience on bottom-up development. The case of Chung Poong Area in Je Cheon rural theme park used in this study has prioritize residents' involvement in planning procedure. This project emphasized the importance of residents' participation and their role in the entire process of tourism development that ranges from project site decision to the major business decision. Thus, this study suggests a direction that can be used for the future rural theme park projects and community-based project related to planning and design in rural area. 농어촌 테마공원(Rura1 Theme Park) 사업은 2007년부터 농림수산식품부에서 지속적으로 증가하고 있는 농촌관광 수요를 충족하고 농촌지역의 활성화를 위해 진행하고 있는 사업으로 도농교류 및 지역경제 활성화를 목적으로 하고 있다. 농어촌 테마공원은 농촌지역이 가지고 있는 고유한 자연적,문화적 자원 등을 주제로 지역특색에 맞게끔 다양한 형태의 테마공원을 조성하는 것으로 지역주민의 의견을 적극적으로 수렴하는 상향식 사업으로 진행해 나아가고 있다. 그럼에도 불구하고 사업의 실질적인 주체인 지역주민의 경우 주민참여형 농환지역개발사업에 대한 이해부족과 상향식 사업에 대한 경험부족 등으로 계획수립 과정에서 소외되고 있는 것 또한 현실이다. 본 연구는 제천지구 농어촌 테마공원 기본계획을 수립하는 과정에서 지역주민의 참여를 우선적으로 고려하였으며,대상지 선정에서부터 주요사업 도출과정에 이르기까지 계획수립의 전과정에서 걸쳐서 지역주민의 참여와 역할에 대해서 언급하고 있다. 따라서 향후 농어촌테마공원뿐만 아니라 농어촌지역계획 수립과 관련한 주민참여형 사업에 기초자료로 활용될 수 있는 방안을 제시하고자 한다.

AbstractThe current Education Ministry is activating youth volunteer activities in an effort to hammer out the problems the youth faces. These activities were expected to increase of public benefits and rebuilding of community as well as ego-realization and promotion of social mind of the youth.But, due to lack of appropriate preparation for the enactment of the program, there have not been satisfactory relationship and cooperation among education authorities, schools, and related institutions. some students wrongly think that, because all they have to do is getting a designated point on these mandatory activities, they may idle away their time, not working hard or heartily.Thus, the focus of the present treatise is to study on the new plan for youth volunteer activities through an analytical study on the essence of volunteer activities, the level of domestic youth volunteer activities, the case of foreign youth volunteer activities, and the practical measures of youth volunteer activities.

Omega-3 fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) may be the most protective of all known dietary factors against death from coronary heart disease. New evidence has confirmed the cardioprotective role of these fatty acids on reduction of triglyceride-rich lipoprotein. This study was undertaken to determine whether this effect was due to EPA and/or DHA, and due to reduced very-low density lipoprotein and/or chylomicron. Healthy subjects (n = 33) began with a 4-week, olive oil placebo (4 g/d) run-in period. After a 4-week wash-out period, subjects were randomized to supplementation with 4 g/d of ethyl esters of either safflower oil (SAF), EPA, or DHA for 4 weeks. EPA and DHA supplementation significantly reduced both apolipoprotein B100 on very-low density lipoprotein and apolipoprotein B48 on chylomicron. EPA and DHA supplementation significantly increased preheparin lipoprotein lipase (LpL) activity (P < 0.05). The results suggest that EPA and DHA equally effectively reduces very-low density lipoprotein and chylomicron by increasing LpL activity.

The bending process of a press die is to bend a flat blank to the required angle. There are V-bending, U-bending, Z-bending, O-bending etc. for bending processing, and the basic principle of calculating the unfolding length of die processing is used as the neutral plane length. Since the constant of the length value of the neutral surface is different depending on the type of bending, it is impossible to accurately calculate it. In particular, Z-bending processing is performed twice, and it is set on the upper and lower surfaces of the blank, and bending processing occurs at the same time as the upward and downward bending, and the elongation of the material occurs and the material increases. It is not possible to check with the calculated value, and it occurs in many cases where the mold is modified after start-up. This study aims to minimize die modification by developing a formula to calculate the development length of Z-bend.

박용순,Woo-Hyun Kim,심동오,김호성,정운관,조재환 한국물리학회 2012 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.61 No.12

This study compared the SPECT (single-photon emission computed tomography) images before and after applying an attenuation correction by using the CT (computed tomography) image in a SPECT/CT scan and examined depending of the change in image quality on the CT dose. A flangeless Esser PET (positron emission tomography) Phantom was used to evaluate the image quality for the Precedence 16 SPECT/CT system manufactured by Philips. The experimental method was to obtain a SPECT image and a CT image of a flangeless Esser PET Phantom to acquire an attenuation-corrected SPECT image. A ROI (region of interest) was then set up at a hot spot of the acquired image to measure the SNR (signal to noise ratio) and the FWHM (full width at half maximum) and to compare the image quality with that of an unattenuation-corrected SPECT image. To evaluate the quality of a SPECT image, we set the ROI as a cylinder diameter (25,16, 12, and 8 mm) and the BKG (background) radioactivity of the phantom images was obtained when each CT condition was changed. Subsequently, the counts were compared to measure the SNR. The FWHM of the smallest cylinder (8 mm) was measured to compare the image quality. A comparison of the SPECT images with and without attenuation correction revealed 5.01-fold, 4.77fold, 4.43-fold, 4.38-fold, and 5.13-fold differences in SNR for the 25-mm cylinder, 16-mm cylinder,12-mm cylinder, 8-mm cylinder, and BKG, respectively. In the phantom image obtained when the CT dose was changed, the FWHM of the 8-mm cylinder showed almost no difference under each condition regardless of the changes in kVp and mAs.

박용순,박경석,Joseph W. Kloepper,류충민 한국식물병리학회 2015 Plant Pathology Journal Vol.31 No.3

Certain bacterial species associate with plant roots in soil. The plant growth-promoting rhizobacteria (PGPR) stimulate plant growth and yield in greenhouse and field. Here, we examined whether application of known bacilli PGPR strains stimulated growth and asexual reproduction in the succulent plant Kalanchoe daigremontiana. Four PGPR strains B. amyloliquefaciens IN937a, B. cereus BS107, B. pumilus INR7, and B. subtilis GB03 were applied to young plantlets by soil-drenching, and plant growth and development was monitored for three months. Aerial growth was significantly stimulated in PGPR-inoculated plants, which was observed as increases in plant height, shoot weight, and stem width. The stimulated growth influenced plant development by increasing the total number of leaves per plant. Treatment with bacilli also increased the total root biomass compared with that of control plants, and led to a 2-fold increase in asexual reproduction and plantlet formation on the leaf. Collectively, our results firstly demonstrate that Bacillus spp. promote vegetative development of K. daigremontiana, and the enhanced growth stimulates asexual reproduction and plantlet formation.

Dose-Dependent Effects of n-3 Polyunsaturated Fatty Acids on Platelet Activation in Mildly Hypertriglyceridemic Subjects

박용순,William S. Harris 한국식품영양과학회 2009 Journal of medicinal food Vol.12 No.4

The purpose of this study was to determine dose effects of n-3 polyunsaturated fatty acids (PUFAs) on mean platelet volume (MPV) and platelet count (PLT-CT) in mildly hypertriglyceridemic subjects. Subjects with a serum triglyceride level between 100 and 300mg/dL were placed on a corn oil placebo for 4 weeks and then randomly assigned to groups taking seven capsules per day of placebo (n=47) or one of the following doses of n-3 PUFAs for 20 weeks: 0.5g (n=50), 1g (n=23), or 2g (n=12). At the end of both the placebo period and the treatment period, MPV and PLT-CT were measured without stimulation (baseline 1 following placebo period, baseline 2 following n-3 supplement period) and after ex vivo stimulation with collagen (10μg/mL), cold (4°C), and heat (37°C). Collagen and cold significantly increased MPV, whereas heat lowered MPV regardless of treatment. All stimuli decreased PLT-CT. Only the 2g/day dose of n-3 PUFAs increased MPV at baseline 2 (7.2±0.5 vs. 7.5±0.5fL) and after the cold stimulus (7.5±0.5 vs. 7.8±0.5 fL). There was no dose-dependent effect of n-3 PUFAs on platelet activation; rather, 2g of n-3 PUFAs increased MPV slightly in mildly hypertriglyceridemic subjects.

Real-time energy monitoring systems is a demand-response system which is reported to be effective in saving energy up to 12%. Real-time energy monitoring system is commonly composed of smart-plugs which sense how much electrical power is consumed and IHD(In-Home Display device) which displays power consumption patterns. Even though the monitoring system is effective, users should themselves match which smart plus is connected to which appliance. In order to make the matching work to be automatic, the monitoring system need to have appliance identification algorithm, and some works have made under the name of NILM(Non-Intrusive Load Monitoring). This paper proposed an algorithm which utilizes multiple classifiers to improve accuracy of appliance identification. The algorithm proposes to understand each classifiers performance, that is, when a classifier make a result how much the result is reliable, and utilize it in choosing the final result among result candidates from many classifiers. By using the proposed algorithm this paper make 4.5% of improved accuracy with respect to using single best classifier, and 2.9% of improved accuracy with respect to other method using multiple classifiers, so called CDM(Commitee Decision Mechanism) method.
