Objective:?Sarcopenia, the progressive decrease of skeletal muscle mass and function, is related to functional impairment in the elderly. Muscle mass, mainly composed of appendicular lean mass (ALM), is known to be a heritable trait. Sarcopenia has been a subject of increasing genetic research. However, genetic risk factors in Asian were not thoroughly evaluated. The aim of this study is to identify genetic variants associated with sarcopenia defined by the Foundation for the National Institutes of Health in Korean adults over 65 years old.?Methods:?A total of 1,290 individuals from Ansung cohort was investigated. Sarcopenia was defined as the lowest quantile of ALM adjusted for body mass index (BMI) of the population studied and 254 participants met this criteria. Affymetrix Genome-Wide Human Single Nucleotide Polymorphism (SNP) Array 5.0 was used for genotyping and 308,945 SNP markers passed quality control filter. We performed logistic regression analysis including sex, age and BMI as covariates. Arbitrarily defined?P?value threshold of less than 0.00001 was used for suggestive evidence of association.?Results:?None of the SNP markers passed genome-wide significance threshold of?P?<5×10-8. A variant in SORCS2?(rs6834325), was most significantly associated with sarcopenia in elderly Koreans (odds ratio 0.58, 95% confidence interval=[0.46, 0.72],?P?= 1.50×10-6). Eight other variants had suggestive association and were considered to be functionally relevant to sarcopenia; seven of those including rs2329489 in/near?GRB10?with odds ratio ranging from 1.57 to 1.62 and?P?from 8.49×10-5?to 3.82×10-5, and rs16958069 (0.64, 3.99×10-5) in?RYR3. Among known candidate genes, several variants in?GREM1,?ST18,?MMP?and?INSR?showed nominal significance of?P?<0.05.?Conclusions:?We have identified nine suggestive genetic loci associated with sarcopenia in elderly Korean. As we had limited statistical power due to small sample size, further replication study is required to validate our findings.

Physics analysis of new TRU recycling options using FCM and MOX fueled PWR assemblies

Cho, Ye Seul,Hong, Ser Gi Korean Nuclear Society 2020 Nuclear Engineering and Technology Vol.52 No.4

In this work, new multi-recycling options of TRU nuclides using PWR fuel assemblies comprised of MOX and FCM (Fully Ceramic Micro Encapsulated) fuels are suggested and neutronically analyzed. These options do not use a fully recycling of TRU but a partial recycling where TRUs from MOX fuels are recycled while the ones from FCM fuels are not recycled due to their high consumption rate resulted from high burnup. In particular, additional external TRU feed in MOX fuels for each cycle was considered to significantly increase the TRU consumption rate and the finally selected option is to use external TRU and enriched uranium feed as a makeup for the heavy metal consumption in MOX fuels. This hybrid external feeding of TRU and enriched uranium in MOX fuel was shown to be very effective in significantly increasing TRU consumption rate, maintaining long cycle length, and achieving negative void reactivity worth during recycling.

Objective This study evaluated the psychometric properties of the Korean Anxiety Screening Assessment (K-ANX) developed for screening anxiety disorders. Methods Data from 613 participants were analyzed. The K-ANX was evaluated for reliability using Cronbach’s alpha, item-total correlation, and test information curve, and for validity using focus group interviews, factor analysis, correlational analysis, and item characteristics based on item response theory (IRT). The diagnostic sensitivity and specificity of the K-ANX were compared with those of the Beck Anxiety Inventory (BAI) and Generalized Anxiety Disorder 7-item scale (GAD-7). Results The K-ANX showed excellent internal consistency (α=0.97) and item-total coefficients (0.92–0.97), and a one-factor structure was suggested. All items were highly correlated with the total scores of the BAI, GAD-7, and Penn State Worry Questionnaire. IRT analysis indicated the K-ANX was most informative as a screening tool for anxiety disorders at the range between 0.8 and 1.6 (i.e., top 21.2 to 5.5 percentiles). Higher sensitivity (0.795) and specificity (0.937) for identifying anxiety disorders were observed in the K-ANX compared to the BAI and GAD-7. Conclusion The K-ANX is a reliable and valid measure to screen anxiety disorders in a Korean sample, with greater sensitivity and specificity than current measures of anxiety symptoms.

Background: KAI1/CD82 reportedly slows the metastatic process in a variety of tumors. However, its function is not fully clear. This study investigates the expression of KAI1 in correlation with malignant skin cancers. Objectives: To investigate the expression and clinical significance of KAI1 protein in malignant skin cancers. Methods: KAI1/CD82 expression was evaluated by western blotting in 24 specimens including 6 malignant melanoma (MM), 6 squamous cell carcinoma (SCC), 6 BCC and 6 normal skin specimens. Immunohistochemical staining was performed to measure KAI1/CD82 expression in 6 MM, 6 SCC and 6 BCC. Results: We observed over-expression of KAI1 in the malignant melanoma. The expressions of KAI1 in malignant melanoma were higher than those in SCC and BCC. The KAI1 expressions in malignant melanoma were higher in protein levels compared to SCC and BCC. Western blotting results agreed with immunohistochemistry. Conclusion: KAI1 is highly related to malignant melanoma and may be a useful indicator of malignant melanoma.

Motivational Interviewing Training Using Role Play in Dental Hygiene Students

Ye Seul Han,Young-Sik Cho 한국치위생과학회 2018 치위생과학회지 Vol.18 No.1

The purpose of this study was to develop a motivational interviewing (MI) training program to improve competency in communication and to effect the evaluated changes that would occur in dental students’ counseling techniques as result of the training in the program. The study proceeded through the program via role-play practice, which was explained effectively during the MI program training process. A convenience sample of 43 fourth-year dental hygiene students was recruited. Twenty-two students were randomly assigned to the intervention group and 21 to the control group in the order of recruitment. The theoretical lecture was delivered over 3 hours and the practice was done in parallel by applying cases occurring in clinic settings. The practice was technical training, partner practice, and small group practice. The intervention group received three hour MI lecture while the control group received no lecture. Evaluation through role-play practice was separated according to “researcher’s viewpoint,” “counselor’s role viewpoint,” and “patient’s role viewpoint.” The results of the analysis showed that the intervention group had higher MI skills and ability than the control group. Furthermore, program participants showed positive impressions to the MI training program. The use of coaching sessions improved the MI techniques and counseling skills of dental hygiene students learning MI. The effect of the application of the MI training program was that the MI training improved counseling skills and interviewing abilities. Moreover, continuous training and feedback enhanced MI techniques and core skills. Training using lectures in parallel with practice rather than education through theory alone improved students’ techniques. Application of role play through the combined method of the MI program was confirmed by an effective training method.

The external benefits of expanding the micro photovoltaic power generation in Korea: A contingent valuation study

Cho, Yong-Cheol,Lim, Seul-Ye,Yoo, Seung-Hoon Elsevier 2017 SOLAR ENERGY -PHOENIX ARIZONA THEN NEW YORK- Vol.158 No.-

<P><B>Abstract</B></P> <P>The micro photovoltaic (MPV) is a good alternative for reducing greenhouse gas (GHG) emissions in the residential areas. Therefore, the Korean government has planned to expand the MPV power generation from about 2000 households (6MW) in 2014 to 25,000 households (61MW) by 2017. This article aims to assess the external benefits of this expansion in terms of reducing GHG emissions. To this end, we derive the public’s additional willingness to pay (WTP) for the expansion through an increase in electricity bill using a contingent valuation survey of 1000 Korean households. For the purpose of mitigating the response effect in eliciting their WTP and increasing statistical efficiency in analyzing the WTP data, we employ a one-and-one-half-bounded dichotomous choice question format. Furthermore, we use the spike model so as to model zero WTP responses. The mean additional WTP for the expansion is computed to be KRW 15.48 (USD 0.01) per kWh. This value amounts to 12.4% of the residential electricity price, KRW 125.14 (USD 0.11). We can conclude that Korean households are ready to shoulder some of the financial burden of expanding the MPV power generation.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Korea plans to expand micro photovoltaic (MPV) power generation from 6MW to 61MW. </LI> <LI> We assess the external benefits of this expansion using contingent valuation. </LI> <LI> We elicit the additional willingness to pay (WTP) for expanding MPV power generation. </LI> <LI> The mean additional WTP is estimated to be KRW 15.48 (USD 0.01) per kWh. </LI> <LI> This value amounts to 12.4% of the residential electricity price. </LI> </UL> </P>
