본 연구는 우리나라 장수노인들의 식품섭취상태를 분석 평가하고 건강한 장수를 위한 식생활 지침의 설정을 위한 기초자료를 얻고자 수행되었다. 연구 대상은 경상북도 성주군에 거주하는 85세 이상 고령노인 중에서 일상 생활에 문제가 없는 224명이었으며 이들을 대상으로 반복 24시간 회상법을 이용하여 1년간 4회의 계절별 식품 섭취 조사를 실시하였으며 결과를 요약하면 다음과 같다. 계절별 식품군별 섭취량에 있어서 남자노인은 감자류의 섭취량이 여름철에 유의적으로 높고, 버섯류의 섭취량이 가을철에 유의하게 높은 것을 제외하고는 모든 식품군의 섭취량에 있어 계절별 차이가 나타나지 않았다. 여자노인의 경우 곡류, 당류, 두류, 채소류, 과일류, 조미료류, 음료 및 주류, 육류, 우유류, 어패류의 섭취량이 겨울철에 유의하게 높았으며, 종실류, 해조류, 난류의 섭취량은 계절에 따른 차이가 없었다. 조사 대상자들의 연평균 1일 총 식품 섭취량은 594.4±186.1 g이었으며 이 중에서 513.5±161.2 g(86.4%)는 식물성 식품군으로부터 섭취하였고 79.3±56.7 g(13.3%)는 동물성 식품군으로부터 섭취하였다. 섭취량이 가장 높았던 식품군은 곡류였으며그 다음이 채소류, 과일류, 어패류, 음료 및 주류, 조미료류, 두류, 육류, 우유류, 감자류 등의 순이었다. 장수 노인대상자들의 음식별 섭취빈도는 밥류에 있어서는 쌀밥의 섭취비율이 80.1~89.2%로 가장 높았으며 국과 찌개류에서는 쇠고기국, 된장국, 된장찌개의 섭취 비율이 높았다. 어육류 식품의 경우 조기구이의 섭취비율(9.4~12.7%)이 높았으며, 해조류 식품의 경우 김구이의 섭취비율(7.4~20.5%)이 높았고, 각 계절마다 계절식품의 섭취비율이 높았다. 김치류의 경우 배추김치의 섭취비율이 4계절 모두 70% 이상으로 높게 나타났다. 일품요리류는 손쉽게 조리할 수 있는 라면과 국수의 섭취비율이 높았다.<br/> 본 연구의 결과에서 경북 성주지역 장수 노인들의 계절별 식품 섭취량에 있어 겨울철의 식품 섭취량이 다른계절에 비해 유의하게 높았으며, 남자노인보다는 여자노인이 식품섭취에 계절에 의한 영향을 더욱더 많이 받는 것으로 나타났다. 또한 장수 노인들은 가공식품보다는 계절마다 제철에 생산되는 자연 식품의 섭취비율이 높았다. 전반적으로 장수노인들은 소식의 경향을 보였으며 이와 같은 소식습관과 신선한 식물성 식품들의 일상 섭취가 건강한 장수에 영향을 미쳤을 가능성도 있을 것으로 사료된다. The purpose of this study was to estimate food intakes of the long-lived elderly and to obtain the data for establishing dietary guidelines that may be recommended for the general population for the sake of longevity. The subjects of the study were 224 elderly people of age over 85 years living in Kyungpook Sung-Ju area who have no problem in daily living. The food consumption survey was carried out seasonally by the repeated 24-hr recall method for one year. The subject group for this study was composed of 58 males and 166 females, the average age being 87 years old. Food intakes of the winter were more than any other seasons. The mean daily total food intake per capita was 594.4 g, 513.5 g (86.4%) from plant foods and 79.3 g (13.3%) from animal foods. The sequence of high intakes of food groups were cereals, vegetables, fruits, fishes, legumes and meats. Boiled white rice, beef soup, soybean paste soup, soybean paste stew, broiled yellow croaker, kimchi, ra myon and broiled noodles were consumed most frequently. In conclusion, the subjects consumed much more plants foods than animal foods and consumed more natural and seasonal foods than processed foods and also showed food habits of eating small meals. Dietary habits of eating small meals containing abundant amount of fresh plant foods might partially contribute to the longevity of the subjects.

Lee, Jae-Hyun,Jung, Ki-Won,Kim, Hee-Kyung,Koo, Ki-Tae,Kim, Sung-Hun The Korean Dental Association 2016 대한치과의사협회지 Vol.54 No.12
Purpose : The purpose of this study was to compare the plaque removal effects of vacuum oral cleaner developed for the patients with limited mobility with those of manual toothbrushes and high pressure injection oral cleaner (dental water jet). Meterials and methods : Thirty human subjects were measured with Patient Hygiene Performance index (PHP index) and O'Leary index before and after the use of toothbrush, high pressure injection oral cleaner and vacuum oral cleaner. These three different oral hygiene methods were conducted with seven-day intermittence. Then the statistical analysis was carried out to define plaque removal rate of three different oral hygiene methods (${\alpha}=.05$). Results : According to the efficacy analysis of plaque removal before and after the oral cleaning using each of three methods, significant reduction in plaque after the treatment compared to the previous state when using toothbrush, high pressure injection oral cleaner, and vacuum oral cleaner was observed (P < 0.001). PHP index of tooth brushing was higher than that of the high pressure injection oral cleaner, while PHP index of vacuum oral cleaner did not show significant difference from either of the other two methods. There was no significance difference in O'Leary index among the three methods. Conclusion : Effect of plaque removal using the vacuum oral cleaner is comparable to that of manual tooth brush or high pressure injection oral cleaner, so it will be helpful for self-oral hygiene care of the patients with limited mobility.

Background: A Poly-L-lactic acid (PLLA) is a soft tissue filler known to stimulate collagen production. Objectives: The purpose of this study is to analyze objective volumetric effect of PLLA in different setting of injection schedule on the cheek. Methods: A split-face, evaluator-blind randomized study in 24 volunteers was conducted. One side was injected 3 times with dose of 4cc per visit at week 0, 4, and 8, and the other side was injected 2 times with dose of 6cc per visit at week 4 and 8, respectively. Volunteers were evaluated with facial volume loss scale (FVLS) from 1 to 5(most severe) and objective volumetric values using Vectra-CR 3D camera system. Results: Improvement of FVLS was statistically significant (p<0.05) and maintained until 12 months in both injection side. Vectra showed volumetric difference (cc) between before and after injection. In 3 times injection side, it was increased from 2.12cc (after 1 month) to 3.17cc (after 12 months). In 2 times injection side, it was increased from 2.26cc (after 1 month) to 3.19cc (after 12 months). Gradual volumetric improvement over 12 months was statistically significant in both sides (P<0.05, generalized linear model). There was not statistically significant difference between three and two times injection side in both FVLS and Vectra. There was no severe adverse event. Conclusion: PLLA filler has continuous volumetric effect and there was not a significant difference by injection times at the same total injection volume.

Background: Adipose tissue is recently recognized as not only energy reservoir but also endocrine organ producing proinflammatory cytokines. Especially the impact of visceral adipose tissue(VAT) in critical illnesses has been proposed, but researches on the association between VAT and sepsis were scarce and quantitative measurement of VAT had not been used. Methods: In this retrospective cohort study, we enrolled patients with sepsis who examined abdominal computed tomography( A-CT) within 1 month of occurrence of sepsis, among the patients admitted to intensive care unit(ICU). Age, sex, anthropometric values, comorbidities and APACHE II score were reviewed. The areas of VAT and total adipose tissue(TAT) on the section of A-CT image of the umbilicus level were measured by calculating pixels presenting fat density. Results: Among 287 patients admitted to ICU due to sepsis, 178 patients were included for this study. Median age was 65 and 59.0% were men. In-hospital mortality rate was 57.9%. Women had higher TAT and subcutaneous adipose tissue, lower VAT/TAT ratio compared to men. The amount of VAT and VAT/TAT ratio were higher in in-hospital mortality group than in survivor group(90.41cm2 vs. 63.83cm2 and 45.88% vs. 32.79%, p=0.001 and <0.001, respectively). After adjusting age, sex, APACHE II score and comorbidities, multivariate logistic regression analysis revealed that the amount of VAT and VAT/TAT ratio were independent prognostic factors of sepsis with obvious dose-dependent relationship(VAT/TAT ratio quartile 3: OR 8.832, p<0.001 and quartile 4: OR 29.477, p<0.001, compared to quartile 1 respectively). Conclusion: The amount of VAT and VAT/TAT ratio quantitatively measured by A-CT were positively correlated with mortality in sepsis, and this association was dose-dependent. Visceral obesity should be considered as the poor prognostic factor of sepsis.
GaZnO as a Transparent Electrode to Silicon Carbide
Lee, Jung Ho,Kim, Ji Hong,Do, Kang Min,Moon, Byung Moo,Joo, Sung Jae,Bahng, Wook,Kim, Sang Cheol,Kim, Nam Kyun,Koo, Sang Mo Trans Tech Publications, Ltd. 2012 Materials science forum Vol.717 No.-
<P>The characteristics of Ga-doped zinc oxide (GaZnO) thin films deposited at different substrate temperatures (TS~250 to 550oC) on 4H-SiC have been investigated. Structural and electrical properties of GaZnO thin film on n-type 4H-SiC (100)were investigated by using x-ray diffraction, atomic force microscopy (AFM), Hall effect measurement, and Auger electron spectroscopy (AES). Hall mobility is found to increase as the substrate temperature increase from 250 to 550 oC, whereas the lowest resistivity (~3.3 x 10-4 Ωcm) and highest carrier concentration (~1.33x1021cm-3) values are observed for the GaZnO films deposited at 400 oC. It has been found that the c-axis oriented crystalline quality as well as the relative amount of activated Ga3+ Introduction ions may affect the electrical properties of GaZnO films on SiC.</P>
Determination of Pd(II) and Pt(II) Metal Cyano Complexes Using Capillary Electrophoresis
Lee, Hue-Jin,Lee, Sang-Ho,Chung, Koo-Soon,Lee, Kwang-Woo Korean Chemical Society 1994 Bulletin of the Korean Chemical Society Vol.15 No.11
Mixtures of cyano complexes of palladium(II) and platinum(II) were separated by capillary electrophoresis using a fused silica capillary as a separation column and 30 mM phosphate buffer (pH 7) containing 15 wt. % acetonitrile as a running buffer. By virtue of the high ionic mobilities of the negatively charged cyano complexes of Pd(II) and Pt(II), they were separated using a cathodic injection and anodic detection scheme. The metal complexes eluted through the capillary were detected by direct UV absorption at 214 nm. A linear relationship between peak area and concentration was obtained for both ions and the detection limit was lower than $10^{-14}$ mole. The proposed method was applied to real sample, e.g., anode slime obtained from an electrolytic copper refinary, as a method for the simultaneous determination of palladium and platinum.
