Objectives: The purpose of this study was investigation of quality and quantity of nutritional intake related oral health status among Korean elders. Methods: The nutrient intake and the dietary quality was evaluated on the basis of the Dietary Reference Intakes For Koreans(KDRIs). Chi-square test for Complex Samples was used to determine the relationship between oral health and inadequate nutrient intake in Korean elders. The complex samples general linear model was used to test difference of average value difference of nutrient intake percentage compared to dietary reference intake(DRI), energy intake rate from three major nutrients, average mean adequacy ratio(MAR) and index of nutritional quality(INQ) related oral health status. Age, sex and total energy intake was compensated for this analysis. PASW 18 was used for statistical analysis. Results: We could found the difference of the nutrient intake and the dietary quality related oral health status among Korean elders. Especially, Nutrient intake percentage and component ratio of protein among energy intake rate from three major nutrient was lower as oral health status became worse. The percentage of subjects with nutritional intakes under showed highest level in worst oral health status. As oral health status became worse, average mean adequacy ratio(MAR) was lower and the number of nutrient of which index of nutritional quality(INQ) was under 1 was more. Conclusions: From the result above, this study clearly shows the level of oral health affecting the inequalities of eating and the food for the people. And the various propose of oral health policies is needed for vulnerable groups who needs solution to solve the problem of inequality of food distribution where intensive distribution of nutrition problem occurred. Sufficient, safe, and a variety of healthy food intake is a fundamental right of our people. And also, to apply this policy in reality, institutional arrangements and organizations, and specific performing system will be needed. (J Korean Soc Dent Hygiene 2011; 11(6):833-841)

Esophageal duplication is rare congenital malformation of the gastrointestinal tract, and it may occur at any level in the esophagus, but more frequently in the lower third. There are 2 types of it, cystic and tubular, the former is more common than the latter, and some- times its also classified as communicating type or non-communicating type whether the accessory lumen has opening to the esophagus or the adjacent structure or not. The clinical symptoms are variable according to the location, the type of esophageal dulication. We experienced an asymtomatic case considered as partial tubular duplication of esophagus that had two longitudinal folds those were not changed during the degluttination and connected the two orifices in the lower esophagus. So we report one case of partial tubular duplication of esophagus with review of the literatures.

아위느타리버섯에 대한 재배사내 CO₂ 농도에 따른 생육 및 수량성을 검토하여 시설재배에 적합한 CO₂ 농도를 구명하고자 재배사의 CO₂ 농도를 500, 1000, 1500, 2000ppm으로 조절하면서 재배시험을 실시한 결과, 자실체 수량은 CO₂ 1000ppm 처리에서 102.4g/병으로 가장 높았고, CO₂ 2000ppm 처리에서 75.1g/병으로 가장 적게 나타나 통계적으로 유의하였다. CO₂ 농도에 따른 초발이 소요일수는 CO₂ 농도가 증가할수록 길어지는 경향으로 CO₂ 500, 1000ppm 처리에서는 6일, CO₂ 1500, 2000 처리에서는 각각 8일과 9일이 소요되었으며 생육일수 또한 같은 경향을 나타내어 수확에 소요되는 전체 재배일수는 CO₂ 500ppm 처리에서는 16일, CO₂ 2000ppm 처리에서는 23일로 나타났다. 아위느타리버섯의 생육상황은 발이개체수는 1500ppm 처리에서 12.2개, 유효경수는 1000ppm 처리에서 2.8개로 가장 많은 경향이었고, 자실체 갓직경, 대직경, 대길이 등은 처리간 차이가 없었으며, 자실체의 비정형과 발생율은 CO₂ 500, 1000, 1500ppm 처리에서는 4.0~7.3%로 유의차가 없었으나 2000ppm 처리에서 13.8%로 현저히 증가하였다. 수확기 자실체의 중량에 따른 등급별 분포는 50g 이상은 갓의 신장이 1~2개체에서만 두드러졌던 500ppm 처리에서 10.3%으로 가장 높았으나, 상품화가 가능한 상등급과 중등급의 비율은 CO₂ 1000ppm 처리에서 65.4%로 가장 많았고. CO₂ 2000ppm 처리에서는 20g 이하의 하품의 비율이 59.3%로 가장 높은 것으로 나타났다. 수확기 자실체 갓과 대의 경도, 응집성, 검성 등의 물리적 특성은 처리간 큰 차이가 없어 CO₂ 농도가 수확기의 자실체 물성에는 영향을 미치지 않는 것으로 나타났다. 이와 같은 결과로 아위느타리버섯 대량생산을 위한 시설재배사의 적정 CO₂ 농도는 자실체 수량과 유효경수가 많고 상품화가 가능한 중량의 개체 생산비율이 높은 CO₂ 1000ppm 처리가 가장 적합한 것으로 나타났다. The effects of CO₂ concentration on fruit-body formation and yield of Pleurotus ferulae (KME65003) mushroom were examined in the growing facilities for bottle cultivation. The CO₂ concentration levels in the growing facilities were 500 ppm, 1000 ppm, 1500 ppm and 2000 ppm of CO₂, controlled by different ventilation amount. Yield of fruit body was highest of 102.4 g/bottle at 1000 ppm treatment and lowest of 75.1 g/bottle at 2000 ppm. As the CO₂ concentration increased up to 2000 ppm, the first pinhead formation and fruit-body growing period took longer, so total growing period took 16 days at 500 ppm, but 23 days at 2000 ppm. The number of pinhead formation was highest of 12.2/bottle at 1500 ppm and valid stipes was highest of 2.8/bottle at 1000 ppm. Fruit body characteristics such as pileus and stipe diameter, and stipe length were not significant at different CO₂ concentration. The fruit body ratio of 20~50 g range among the whole fruit body which was classified by weight was highest of 60.3% at 1000 ppm. As a result, the suitable CO₂ concentration of growth and yield of Pleurotus ferulae was showed as 1000 ppm.

This study was carried out to obtain morphological and physiological characteristics of ear mushrooms for an artificial cultivation. Eighteen strains were cultivated with bag culture and classified into mainly five groups such as brown, black, white, purple and others group. The highest yield was shown in 43007 strain as 98.3g/bag and 43009, 43016, 43025 and 44035strains were more than 60g/bag. Among collected strains, 43007, 43009 and 43035 were selected in this study as superior strains. Three selected strains were investigated for optimal mycelial growth conditions. MCM and GPYM media were selected for the favorable culture medium. The carbon sources of 43007, 43009 and 43035 on mycelial growth were maltose, fructose and glucose, respectively and peptone was selected as a nitrogen source. Highest mycelial growth was observed when the C/N ratio was 10 for 43007 and 20 for 43009 and 43035.

형광체나 반도체의 소자로 사용되는 전이금속화합물 중에서 나노(nano) 크기를 가지는 스피넬 화합물을 합성하였다. 스피넬 화합물의 크기, 합성여부, 열적분석과 화합물의 특성을 확인하기 위하여 열 중량 분석기(TGA), X-선 회절 분석기(XRD), 적외선 흡수 분광기(IR)를 사용하였다. Scherrer식을 이용하여 화합물의 평균 입자 크기가 13~16 nm임을 예측할 수 있었다. 본 논문에 사용된 실험방법은 졸-겔(sol-gel)법을 사용하였으며, 소성 온도는 낮은 온도에서 진행 되었다($350^{\circ}C$). Kinetic 함수인 활성화 에너지와 전환인자를 계산하기 위해서 Kissinger방법과 Arrhenius식을 이용하여 계산하였다. $ZnCo_2O_4$와 $NiCo_2O_4$의 활성화 에너지는 163.42 kJ/mol와 147.01 kJ/mol 값을 가지는 있음을 확인하였다. 그리고 spinel 화합물들의 열역학적 함수(${\Delta}G^{\varphi}$, ${\Delta}H^{\varphi}$, ${\Delta}S^{\varphi}$)를 결정하였다. The spinel compound was obtained by the thermal decomposition of Zn-Co and Zn-Ni gel prepared by sol-gel method using oxalic acid as a chelating agent. The formation of spinel compound has been comfirmed by thermogravimetric analysis (TGA), x-ray powder diffraction (XRD) and infrared spectroscopy (IR). The particle size of 13 nm~16 nm was calculated by Scherrer's equation. The sol-gel method provides a practicable and effective route for the synthesis of the spinel compound at low temperature ($350^{\circ}C$). The kinetic parameters such as activation energy (Ea) and pre-exponential factor (A) for each compound were found by means of the Kissinger method and Arrhenius equation. The decomposition of spinel compound has an activation energy about 155 kJ/mol. Finally, the thermodynamic parameters (${\Delta}G^{\varphi}$, ${\Delta}H^{\varphi}$, ${\Delta}S^{\varphi}$) for decomposition of spinel compound was determined.
