The purpose of this study was to evaluate the microbiological quality, and to assure the safety of the food production process in the university foodservice facilities in accordance with the Hazard Analysis Critical Control Point(HACCP) concepts. The kitchen layout and time-temperature relationship, miciobiological quality(total plate count, coliform) were assessed to identify the critical point during each of the production phases. The results were as follows: 1) The kitchen layout had to be improved because contamination area was not separated from non-contamination area, and work table was in contact with washing sink. 2) Some employee did not follow personal hygiene standards(hand washing), and did not wear proper working uniforms(hair restraints). 3) The production time of tuna salad was 120 min, and environment temperature was 20.1~26.0℃. Improper receiving temperature, inproper holding practices(without cover at room temperature) were observed. 4) In the purchasing phase of the raw materials, the microbiological quality of green pepper was not at acceptable level based on the TPC(2.3×10^6CFU/g)and coliform(>14,000 MPN/g). During washing phase TPC was decreased about 3 log cycle. After cutting and holding phase the level of TPC and coliform were increased rapidly. At serving phase the microbiological quality of tuna salad were not at acceptable level(TPC 3.3×10^6 CFU/g, coliform 11,000 MPN/g) according to the standard set(TPC <10^5 CFU/g, coliform <100 MPN/g) by Sorberg et al. 5) For tuna salad, critical control points were purchasing and receiving of fresh vegetables, washing, cutting, holding, mixing and serving phase.

본 연구에서는 사용된 가시오가피 영지버섯 발효물과 가시오가피 상황버섯 발효물에 대한 열수추출물을 최고 2 g/kg의 농도로 단회 투여한 SD-rats에 체중 변화, 임상증상 등에서 어떠한 독성도 관찰할 수 없었으며, 1 g/kg 이하의 농도로 4주간 반복 투여한 SD-rats에서도 체중변화, 임상증상, 장기 무게, 혈액학적 성상, 혈액생화학적 성상 등에서 어떠한 독성과 비정상적인 소견을 관찰할 수 없었다. 따라서, 본 연구의 결과로 볼 때 가시오가피 영지버섯 발효물 열수추출물(FM-5111)과 가시오가피 상황버섯 발효물 열수추출물(FM-5131)은 본 연구에서 사용한 농도 내에서의 안전성을 확인할 수 있었다. 황 함유 아미노산의 결핍은 여러 가지 간질환 등의 증상을 야기한다(27). 또한, Choi와 Ahn(28)은 오가피 부위별 50% (v/v) 메탄올 추출액의 전자공여능은 줄기 추출물에서 90.21%, 뿌리 추출물에서 85.71%로 높은 활성을 보고하여 오가피의 항산화능을 규명하였다. 따라서, 본 연구에 사용된 시료 또한 항산화능과 같은 기능성을 가질것으로 사료되며, 추가 연구로 아미노산 분석을 통해 황 함유 아미노산의 함량 변화를 분석하고 간 기능 개선 효능을 평가하여 안전성이 확보된 기능성 식품소재 개발 연구를 진행할 계획이다. In this study, the products of Acanthopanax senticosus fermentation were derived from the mycelia of 2 mushrooms, Ganoderma lucidum and Phellinus linteus, to determine their safety in Sprague-Dawley rats. Rats were orally administered the water extracts of A. senticosus fermentation products with G. lucidum (FM-5111) or P. linteus (FM-5131) at dose levels of 0.5, 1.0, or 2.0 g/kg for the single-dose toxicity test and 0.25, 0.5, or 1.0 g/kg for the repeated-dose toxicity test. There were no significant differences in body weight gain, feed intake, or water consumption between control and FM-5111- or FM-5131-treated rats. Hematological and blood biochemistry analysis revealed that none of the investigated parameters were affected by the A. senticosus fermentation products, and no remarkable lesions were observed upon histopathological analysis. We conclude that the A. senticosus fermentation products obtained from mushroom mycelia are safe for long-term administration and could be considered as multi-functional nutrients for the improvement of liver function and immunity.

Sun-youp Park,Jin Choi1,Jung Hyun Jo,Ju Young Son,Yung-Sik Park,Hong-Suh Yim,Hong-Suh Yim,Hong-Kyu Moon,Young-Ho Bae,Jang-Hyun Park 한국우주과학회 2015 Journal of Astronomy and Space Sciences Vol.32 No.3

An algorithm to automatically extract coordinate and time information from optical observation data of geostationary orbit satellites (GEO satellites) or geosynchronous orbit satellites (GOS satellites) is developed. The optical wide-field patrol system is capable of automatic observation using a pre-arranged schedule. Therefore, if this type of automatic analysis algorithm is available, daily unmanned monitoring of GEO satellites can be possible. For data acquisition for development, the COMS1 satellite was observed with 1-s exposure time and 1-m interval. The images were grouped and processed in terms of “action”, and each action was composed of six or nine successive images. First, a reference image with the best quality in one action was selected. Next, the rest of the images in the action were geometrically transformed to fit in the horizontal coordinate system (expressed in azimuthal angle and elevation) of the reference image. Then, these images were median-combined to retain only the possible non-moving GEO candidates. By reverting the coordinate transformation of the positions of these GEO satellite candidates, the final coordinates could be calculated.

The subject was selected as appointing each 100 persons of male/female middle school 3rd students randomly from 4 areas, and performed analysis about the developmental difference according to subject's residential area and the increase ratio according to grades based on data from health record, then also examined BMI. Average/standard deviation of male/female physique & physiacal fitness was calculated respectively as well as in creased amount with collected data, and two-way ANOVA analysis was performed to compare physique and physical fitness. one-way ANOVA analysis was also performed to examine difference per residential area according to grades in case a correlation was observed between grades and residential area. The conclusions is as follows; 1. In the matter of male students, height , weight, chest, sitting height and fatness at urban area showed the highest value, and weight of rural area, height of sea area, chest of mine area showed lower value respectively. Amount of annual increase of height and weight was observed significantly from 1st grade to 2nd grade than from 2nd grade to 3rd grade, and male students of urban area showed highest value among overall school years. Chest of rural area showed the highest increase degree from 2nd grade to 3rd grade th from 1st grade to 2nd grade while no significance was onserved among school years at sitting height except slight decrease tendency as promotion to higher school year. Fatness in urban area showed the highest value for all school years with many cases of over-weight among 4 areas that indicates fatness is arising according to increase of weight and height. 2. In the matter of female students, no significance was observed at heigh, weight, chest according to their residential area, and amount of increase of weight and sitting height even decreased as promotion while mine area showed the highest degree of increase. No significant different was also found at fatness according to residential areas while 1st grad at sea are, 2nd grade at mine area and 3rd grade at urban/mine area showed higher frequency at over-weight case. 3. In the matter of male students, much higher record of 50m sprint was observed at rural/mine area, and the record of mine area increased most significantly as promotion. Overall tendency of increase was found as promotion at total area, and annual development decreased as being 2nd grade except urban area in which high improvement was observed. Similar feature was found at sit-up and urban area showed higher improvemendt of 2nd grade and 3rd grad. Mine area showed high record of standing long jump at 1st grade and 2ne grade while rural area shoued the highest impromement from 1st grade to 3rd grade. 1st grade of urban area, 2nd grade of rural area and 3rd grade of mine area showed high record at sit-stretching, and the highest improvement was observed at mine area from 1st grade to 3rd grad. Continuous improvement was found at running/walking long according promotion as 1st grade/3rd grade at sea area and senior at mine area showed the highest record respectively. 4. In the matter of female students, there was no significance at 50m sprint according to residential area as well as at degree of improvement by promotion. 1st grade of urban area, 2nd grade of sea area and 3rd grade of mine area showed the greatest record at 50m sprint. Hang-down record of rural area and sit-up record of urban area showed the highest one among whole school years respectively. The highest improvement degree from 1st grade to 3rd grade at standing long jump was found at ural/mine area.

Polygonatum odoratum이 당뇨병 쥐의 체내 생리활성에 미치는 영향

최현주 인제대학교 2004 仁濟論叢 Vol.19 No.1

당뇨병(Diabetes mellitus)은 고혈압, 동맥경화증, 당뇨병 망막증, 신증, 말초 신경증, 고지혈증 등의 합병증을 일으키는 만성 대사성 질환으로 알려져 있으며, 현재 국내외에서 천연식물을 이용한 항당뇨병 소재의 개발에 관심이 모아지고 있다. 본 연구에서는 우리나라의 차식품으로 이용되어온 둥글레(Polygonatum odoratum)의 항당뇨병성 효과를 평가하기 위하여 혈당과 지질대사물 수준 및 간에서의 항산화 방어계에 미치는 영향을 알아보았다 당뇨병 흰쥐를 대상으로 하여 15일 동안 둥글레(Polygonatum odoratum) 식이를 투여하였으며, 식이군은 control basal diet group(CONT군)과 Polygonatum odoratum 10% diet group(PO10군), Polygonatum odoratum 20% diet group(PO20군)의 세 군으로 하였다. 실험 마지막 날의 체중은 CONT군에 비하여 PO10군, PO20군의 모든 실험군에서 유의적인 차이는 없었다. 간장 무게가 CONT군에 비해 모든 실험군에서 유의적으로 낮았으나 정상쥐의 간장 무게와 비교하여 볼 때에는 유사한 정도였다. 신장 무게는 CONT군에 비해 PO10군과 PO20군에서 유의적으로 낮았으나 이러한 수치는 정상쥐의 간장과 신장 무게 범위에 속하였다. 모든 실험군의 췌장 무게는 CONT군과 유사하였다. 실험 마지막 날, 혈당 수준은 CONT군과 비교하여 PO10군과 PO20군에서 유의적인 감소를 보였으며, 실험 마지막 날의 혈청 중성지방의 농도의 변화는 CONT군과 비교하여 PO20군에서 유의적으로 감소하였고, 총콜레스테롤 농도는 CONT군에 비해 PO10군과 PO20군에서 유의적으로 감소하였다. 그러나, HDL-콜레스테롤 농도는 CONT군에 비해 PO20군에서 증가하는 경향을 보였으나 유의적인 차이는 없었다. AST와 ALT 활성은 PO10군과 PO20군에서 유의적인 감소를 보였다. 한편, 간 조직의 catalase 활성은 CONT군에 비해 PO10군과 PO20군에서 유의적인 증가를 보였으며, glutathione reductase 활성은 CONT군에 비해 PO20군에서 유의적인 증가를 보였다. 그러나, glutathione peroxidase 활성은 COHT군과 비교해서 모든 실험군에서 유의적인 차가 없었다. 본 연구 결과를 볼 때에, 혈당 강하효능이 있는 둥글레가 당뇨병에 있어서 항산화효소로서는 간 조직의 catalase와 glutathione reductase 활성 증가에 영향을 주는 것으로 나타나서, 혈당 이외에 당뇨병에서 문제가 되고 있는 항산화계와 관련되어 건강소재로서의 활용 가능성이 있다고 사료된다. Diabetes mellitus, a chronic disease resulting from insulin secretion or action, is associated with several complications related to the abnormal antioxidative system. Therefore, this study was performed to investigate the effects of Polygonatum odoratum on biological activities in streptozotocin(STZ)-induced diabetic rats. Male adult Srague-Dawley rats were induced diabetes mellitus by the STZ injection(45mg/kg body weight) into e intraperitoneum and divided into three diet groups; control basal diet group(CONT), Polygonatum odoratum 10% diet group(PO10), and Polygonatum odoratum 20% diet group(PO20). All diets contained same caloroes containing 60% carbohydrate, 20% protein, and 20% fat by kcal. Fasting blood samples were collected at the first day for the intial values and at the 15th day after feeding for the final values, s-aspartic aminotransferase(AST), and s-alanine aminotransferase(ALT) activitites were measured. Catalase, glutathione reductase(GSR), and glutathione peroxidase(GSH-px) were also measured in the liver of the diabeteic rats. The final levels of s-glucose in the PO10 and PO20 groups were significantly lower than those in control group. The final levels of s-triglycantly in the PO20 group and s-total cholesterol in the PO10 and PO20 group were significantly lower than those in the control group. However, the final lovels s-HDL-cholesterol were not different among all groups. The s-AST and s-ALT activitites in the PO10 and PO20 groups decreased significantly than in the control group. Hepatic catalase activities in the PO10 and PO20 groups increased significantly than in the control group. Hepatic GSR activity in the PO20 group was significantly greater than that in the control group. However, there was no significant difference in the GSH-px activity among groups. It is concluded that orally administered Polygonatum odoratum has hypolipidemic and antioxidative effect in streptozotocin induced diabetic rats.
