Purpose: The aims of this study were to identify prevalence and identify factors related to sarcopenic obesity among community-dwelling elderly women. Methods: This is a secondary analysis of the prospective cohort study. Our analysis included 338 elderly women (${\geq}65$ years old) in South Korea as a part of the Community-dwelling Older Adult Health Cohort (COHC) Study (2014-2015). Sarcopenic obesity was defined as the Asian Working Group of Sarcopenia recommendations and upper two quintiles for percentage body fat. Logistic regression analysis was used to determine the factors related to sarcopenic obesity including chronic diseases, medications, stress, fatigue, depression, exercise, level of proteins on body compositions, smoking, and alcohol use. Results: The prevalence of sarcopenic obesity was 6.2%. A lower protein on body compositions (OR 0.017, 95% CI 0.003-0.081, p< .001), a larger number of medications (OR 2.104, 95% CI 1.404-3.152, p< .001), and a higher level of fatigue (OR 1.255, 95% CI 1.023-1.541, p= .030) were related factors of sarcopenic obesity. Conclusion: The findings suggest that nutritional interventions focusing on protein intakes should be needed to prevent sarcopenic obesity among the elderly women. Polypharmacy issue for preventing adverse outcomes and level of fatigue as indicator for early identification are also considered to develop community prevention programs.

조피볼락을 절식시켰을 때 사료의 n-3HUFA 함량에 따른 체성분의 변화를 조사하기 위해 n-3HUFA 함량이 다를 6종의 사료 $(n-3HUFA\; 0\~1.5\%)$로 10주간 사육한 조피볼락을 9주간 절식시킨 결과, 9주 절식 후의 체중감소율은 $14.0\~l7.1\%$ 범위로서 n-3HUFA 함량이 높은 사료를 섭취한 실험구일수록 체중감소가 적었다. 절식기간 중 전어체의 일반성분에 있어서는 모든 실험구에서 수분함량이 증가하고 지질함량은 감소하는 경향을 보였으며, 특히 n-3HUFA 함량이 낮은 사료구$(n-3HUFA\;0\~0.3%)$에서 지질함량의 상대변화비율이 높았다 단백질함량은 n-3HUFA 첨가 사료구에서 모두 절식 5주째 까지는 감소하다가 그 이후에는 일정한 값을 유지한 반면, n-3HUFA 무첨가 사료구는 5주 이후에도 계속 감소하여 n-3HUFA 함량에 따른 차이를 나타내었다. 전어체의 극성지질은 절식기간 중 각실험구 모두 대체로 일정한 값을 유지하였으나, 비극성지질이 감소한 결과, 절식기간이 경과함에 따라 극성지질/비극성지질 비가 증가하여 비극성지질이 절식시의 주 에너지 원으로 사용되었다. 절식후 전어체 극성지질의 DHA 함량은 절식전에 비해 큰 폭으로 증가하였으나, 비극성지질의 지방산조성에는 특별한 변화가 없었다.

This study was carried out to investigate the effects of various dietary lipid sources on the growth performance, body composition, and fatty acid profiles of juvenile fancy carp (Cyprinus carpio var. koi). Three replicate groups of fish (initial mean body weight, 15.1±0.18 g) were fed one of five experimental diets containing fish oil (SLO), soybean oil (SO), linseed oil (LO), lard (LA), or a mixture of SLO, SO, and LO (Mix) for 8 weeks. Fish fed the LA diet gained less weight than did fish fed the LO diet. The feed efficiency and protein efficiency ratio of fish fed the LA and Mix diets were lower than those of fish fed the SO and LO diets. The body lipid content of fish fed the SO diet was lower than those of the other groups. Whole-body fatty acid compositions reflected the fatty acid compositions of dietary lipid sources. Fish fed the SO diet had high concentrations of linoleic acid and arachidonic acid, whereas fish fed the LO diet were rich in linolenic acid. Fish fed the SLO diet had significantly higher levels of eicosapentaenoic acid and docosahexaenoic acid compared with fish fed the SO, LO, and LA diets. The results of this study suggest that SO or LO could be used as a replacement for SLO in the diets of juvenile fancy carp without any negative effects on growth and feed utilization when the dietary essential fatty acid requirements are satisfied for juvenile fancy carp.

This study is proposed to find an appropriate body for high expansion glass ceramics of ${Na}_2O-{Al}_2O_3-{SiO}_2$ system. The compositions of basic glasses are selected to be melted easily and to be crystallized into nepheline with various contents of alumina. The crystallization temperatures of basic glasses are determined by DTA. The crystals in the basic glasses developed by heat treatment are investigated by X-ray diffraction analysis, and thermal properties such as expansion coefficients, fusion points are measured. We find, therefore,that crystallization temperatures, crystal phases and thermal properties are affected by content of alumina.

There is currently no reference for intake of lysine for Chinese people; therefore, the present study was conducted to determine the lysine requirement of Chinese young male adults on a habitual Chinese mixed diet based on the modified indicator amino acid oxidation method. Seven young men with a mean age of $23.7{\pm}2.2$ years that were healthy based on questionnaire, physical examinations and screening tests were evaluated. Subjects were evaluated over five consecutive 7 day periods, during which time they were administered decreasing amounts of lysine via the diet (65, 55, 45, 35, $25mg{\cdot}kg^{-1}{\cdot}d^{-1}$). Subjects were allowed to adapt from day 1 to 6 and the isotopes were measured on day 7 in each period. The subjects' body weights, body compositions and plasma proteins were also examined during the study. Amino acid kinetics were measured based on the indicator amino acid oxidation technique using the $^{13}CO_2$ release rate and phenylalanine oxidation rate to estimate lysine requirements. Body weights, body compositions, and plasma proteins of subjects did not change significantly relative to those at baseline. The mean and the upper 95% CI of lysine requirements of Chinese habitual diets were determined to be 58.41 and $70.09mg{\cdot}kg^{-1}{\cdot}d^{-1}$, respectively, based on the $^{13}CO_2$ release rate and 54.28 and $65.14mg{\cdot}kg^{-1}{\cdot}d^{-1}$, respectively, based on the phenylalanine oxidation rate.

화력발전소에서 발생하는 석탄 바닥재를 효과적으로 재활용하기 위해 여러 가지 폐기물을 함유한 점토소지와 바닥재를 첨가한 점토소지의 가소성 지수를 Atterberg 한계를 이용하여 측정하였다. 그리고 압출 성형을 통하여 가소성 지수가 실제 성형공정에 적용 가능한지를 확인하였다. 수분, 바닥재 함유량, 그리고 석분과 하수오니의 첨가 조성을 달리해 성형이 가능한 조성을 찾았으며, 골재를 만들어 가소성에 따라 성형체의 물성이 어떻게 바뀌는지 조사하였다. 가소성 지수로 압출성형이 가능한 조성을 찾을 수 있으며, 실제로도 압출 성형이 가능한 것을 확인할 수 있었다. 그리고 가소성과 골재 성형체의 물성을 관찰한 결과 첨가 폐기물의 종류에 따라 차이는 있었지만 일반적으로 가소성 지수가 낮아지면, 소지의 비중은 낮아졌으며, 흡수율은 증가하는 경향이 있음을 알 수 있었다.

This paper presents a novel structural composition for artificial bone scaffolds with an appropriate biocompatibility and biodegradability capability. To achieve this aim, carbon nanotubes, due to their prominent mechanical properties, high biocompatibility with the body and its structural similarities with the natural bone structure are selected in component of the artificial bone structure. Also, according to the piezoelectric properties of natural bone tissue, the barium titanate, which is one of the biocompatible material with body and has piezoelectric property, is used to create self-healing ability. Furthermore, due to the fact that, most of the bone tissue is consists of hydroxyapatite, this material is also added to the artificial bone structure. Finally, polycaprolactone is used in synthetic bone composition as a proper substrate for bone growth and repair. To demonstrate, performance of the presented composition, the mechanical behaviour of the bone scaffold is simulated using ANSYS Workbench software and three dimensional finite element modelling. The obtained results are compared with mechanical behaviour of the natural bone and the previous bone scaffold compositions. The results indicated that, the modulus of elasticity, strength and toughness of the proposed composition of bone scaffold is very close to the natural bone behaviour with respect to the previous bone scaffold compositions and this composition can be employed as an appropriate replacement for bone implants.
