Background: Subclinical hypothyroidism(SCH) is a common biochemical abnormality which can be found in routine screening tests of thyroid function. We are increasingly faced with the question of whether its an indication for thyroxine replacement therapy. The effect of thyroxine replacement on lipid profile in SCH has aroused a great interest because of an association of overt hypothyroidism(OVH) with hyperlipidemia and increased risk of coronary artery disease. Method: We prospectively evaluated the changes in lipids and apoproteins before and after thyroxine replacement therapy in 23 patients with SCH and in 37 patients with OVH. We measured serum total cholesterol and triglyceride using autoanalyzer, high density lipoprotein(HDL) chole-sterol by dextran sulfate method, Apo A1 and Apo B by immunonephelometric assay. Results: Thyroxine replacement therapy significantly decreased total cholesterol, low density lipoprotein(LDL) cholesterol and apo B levels, but did not affect the level of triglyceride, HDL cholesterol or apo AI in patients with OVH. In SCH, thyroxine replacement therapy with the doses to normalize serum TSH concentrations also decreased significantly the level of cholesterol and LDL cholesterol albeit apo B levels did not change. Moreover, in most of patients with OVH (11 of 12) and in all of patients with SCH(5 of 5) who had had hyperchlesterolemia before treatment, thyroxine replament normalized their cholesterol and LDL cholesterol levels. Conclusion: In regard to the beneficial changes in blood lipid levels, patients with SCH should be treated, especially in cases who have other risk factors for the development of atherosclerosis. If thyroxine replacement only will reduce the incidence of coronary artery disease in SCH remains to be elucidated by long-term prospective studies(J Kor Soc Endocrinol 11:41-51, 1996).

Chang, Hye-Ja,Lee, Jaung-Sook,Kwak, Tong-Kyung The Korean Nutrition Society 2003 Nutritional Sciences Vol.6 No.2

To prevent food-borne diseases and ensure food safety, foodservice operators have been implementing the HACCP system in their facilities. Employees' knowledge of food safety can be improved through training and, as a result, their food safety behavior can be positively changed. A nonequivalent pretest and posttest control group model was designed to investigate the effectiveness of HACCP-based training on hospital foodservice employees' food safety knowledge and behavior, and to determine relationships between food safety knowledge and food safety behavior. The subjects used in this study were 84 hospital foodservice employees, assigned either to the intervention group (n=44) or the control group (n=40). Data were analyzed using the Statistical Package for the Social Sciences (SPSS). Descriptive statistics were computed, while the Student's t-test and ANCOVA (Analysis of Covariance) were used to investigate significant differences between groups, and the Pearson correlation was used to determine significant correlations. There were significant gains in both food safety knowledge and behavior, after the HACCP-based training. However, no significant correlation was found between food safety knowledge and food safety behavior. Based on this study we conclude that HACCP-based training is effective in improving both the food safety knowledge and food safety behavior of hospital foodservice employees.

강릉수력발전소의 발전수 방류가 강릉 남대천의 수질 및 미생물 분포에 미치는 영향을 조사하였다. 정점 3 상류지역의 발전수 방류는 수질에 상당한 영향을 끼쳐 정점 3 및 정점 4의 수질은 악화되고 정점 5, 정점 6 및 정점 7의 수질은 개선되었다. 미생물 분포도 이와 유사하여 정점 3 및 정점 4의 세포수는 상당히 증가한 반면 정점 5, 정점 6 및 정점 7에서는 대체적으로 감소하였다. 이 결과로 미루어보아 강릉수력발전소의 발전수는 희석효과에 의해 수질 및 미생물 분포를 변화시키는 것으로 사료된다. The effects of water discharged from Kangnung hydropower plant on the water quality and some bacterial population of Namdaecheon Stream, Kangnung were investigated. The water discharged above station 3 affected the water quality significantly; the water quality of station 3 and station 4 took a turn for the worse, however those of station 5, station 6 and station 7 changed for the better. It was also true with the bacterial population; The number of cells of bacteria increased in station 3 and 4, but the number significantly decreased in station 5, station 6, and station 7. The data suggested the idea that the water discharged from Kangnung hydropower plant changed the water quality and some bacterial population by dilution effect.

3차원 CT 영상을 이용한 두개악안면 분석을 위한 계측점의 제안

장혜숙,백형선 대한치과교정학회 2002 대한치과교정학회지 Vol.32 No.5

3차원 CT체서는 환자의 움직임에 의한 오차와 상의 확대나 왜곡을 감소시킨 실측치를 얻을 수 있으며 두개안면부의 입체적인 영상을 구성할 수 있고 원하는 조직이나 구조물의 관찰이 용이하다. 디지털 영상 기술이 빠르게 발전하고 있고 치료의 범위가 더욱 넓어지면서 두개악안면 구조의 3차원적인 분석법의 개발은 시급한 과제가 되었다. 이에 본 연구에서는 Vworks 프로그램™(Cybermed Inc., Seoul, Korea)을 이용하여 정상인과 비대칭 환자의 3차원 CT영상에서 지정이 용이하고 반복재현성이 높은 계측점을 설정하고자 하여 다음과 같은 결론을 얻었다. 1. 건조두개골의 실측치와 Vworks 프로그램을 이용하여 구성한 3차원 CT영상에서의 계측치를 비교한 결과 평균오차가 0.99mm, 확대율이 1.04%로 나타났다. 2. 3차원 CT영상에서 경조직 계측점으로 Supraorbitale, Lateral orbital margin, Infraorbitale, Nasion, ANS, A point, Zygomaticomaxilla, Upper incisor, Lower incisor, B point, Pogonion, Menton, PNS, Condylar inner margin, Condylar outer margin, Porion, Condylion, Gonion2, Gonion3, Sigmoid notch,Basion 등이 임상적으로 유용하다고 판단되었다. 3. 3차원 CT영상에서 연조직 계측점으로 Endocanthion, Exocanthio, Soft tissue Nasion, Pronasale, Alsre lateralis, Upper nostril point, Lower nostril point, Subnasale, Upper lip point, Cheilionm Stomion, Lower lip center, Soft tissue B, Pogonion Menton, Preaurale 등이 임상적으로 유용하다고 판단되었다. Vworks 프로그램으로 3차원 CT영상을 구성하고 계측하는 것이 임상적으로 유용하다고 판단되었다. 또한 위에서 제안된 연조직 및 경조직 계측점들은 3차원 CT영상에서 반복 재현성을 높고 지정이 용이하며 해부학적 특징을 나타내주는 점들로 두개악안면 구조의 3차원적인 진단과 술전, 술후의 예측과 비교에 유용하게 사용될 것으로 사료되는 바이다. Three-dimensional CT imaging is efficient in examining specific structures in the craniofacial area by reproducing actual measurements through minimization of errors from patient movement and image magnification. Due to the rapid development of digital image technology and the expansion of treatment range a need for developing three dimensional analysis has become urgent. Therefore the purpose of this study was to evaluate the percentage of error and magnification of three-dimensional CT using a dried skull and Vworks program™ (Cybermed Inc., Seoul, Korea) and also to obtain landmarks that are easy to designate and reproduce in three-dimensional images using the Vmorph-proto program™ (Cybermed Inc., Seoul, Korea). The following conclusions were obtained ; 1. In the comparison of actual measurements from the dried skull and the three-dimensional image obtained from the Vworks program, the mean error was 0.99mm and magnification was 1.04%. 2. Clinically useful hard tissue landmarks from three-dimensional images were Supraorbitale, Lateral orbital margin, Infraorbitale, Nasion, ANS, A point, Zygomaticomaxilla, Upper incisor, Lower incisor, B point, pogonion, Menton, PNS, Condylar inner margin, Condylar outer margin, Porion, Condylion, Gonionl, Gonion2, Gonion3, Sigmoid notch and Basion. 3. Clinically useful soft tissue landmarks from three-dimensional images were Endocanthion, Exocanthion, Soft tissue Nasion, Pronasale, Alare lateralis, Upper nostril point, Lower nostril point, Subnasale, Upper lip point, Cheilion Stomion, Lower lip center, Soft tissue B, Pogonion Menton and Preaurale. The Vworks program can be considered a clinically efficient tool to produce and measure three-dimensional images. Most of the hard and soft tissue landmarks proposed above are anatomically important points which are also easily reproducible and designated. These landmarks can be beneficial in three-dimensional diagnosis and the prediction of changes before and after surgery.

OCT 플라스미드를 갖는 원유 분해세균에 의한 Octane 분해능

최순영,김창숙,이명혜,황문옥,민경희 숙명여자대학교 자연과학연구소 1991 자연과학논문집 Vol.- No.2

원유 분해세균에 의한 원유 분해능을 조사한 결과, Xanthomonas campestris M12. Xanthomonas sp. M28, Acinetobacter lwoffi G1, and Klebsiella pneumoniae L25, 그리고 Pseudomonas maltophilia N246 등의 순서로 나타났다. Xanthomonas campestris M12, Xanthomonas sp. M28, 그리고 Pseudomonas maltophilia N246 균주 모두 octane 분해시의 온도는 30℃에서 최적이었으며, 최적 pH는 X. campestris M12와 Xanthomonas sp. M28이 7.0∼7.5이었고, P. maltophilia N246이 7.5∼9.0이었다. N246 균주의 최적 NaCl 농도는 3.0∼3.5%이었다. P. maltophilia N246와 X. campestris M12는 모두 플라스미드를 갖고 있음을 확인하였고, N246 균주로부터 플라스미드를 제거하였을 경우 octane 분해능이 소실되었으므로 이 플라스미드 위에 octane 분해 유전자가 있음이 확인되었다. 이 균주의 OCT 플라스미드의 크기는 118kb이었다. 또한, N246 균주는 ampicillin 항생제에 내성을 나타내었다. Xanthomonas campestris M12. Xanthomonas sp. M28. Acinetobacter lwoffi G1, and Klebsiella pneumoniae L25, Pseudomonas maltophilia N246 were screened to increase the ability for crude oil utilization. All of these could utilize hexadecane and octane with the exception of N 246 strain for only octane biodegradation. Thus N246, M12, and M28, strains were specially examined for octane oxidation. Octane biodegradation by three strains showed the optimal conditions at 30C, pH7.0∼9.0 and 0.2∼0.3% octane concentration as a substrate. It was found that P. maltophila N246 and X. campestris M12 had plasmid and the cured plasmid from N246 strain lost octane utilization. Therefore, it was confirmed that certain genes for octane utilization were located on OCT plasmid in N246 strain. The size of OCT plasmid in N246 strain was 118 kb. The N246 strain was resistant to ampicillin.

맹주양;이용구;이숙재;정진아;나성희;김창원;심혜진 순천향대학교 기초과학연구소 2010 순천향자연과학연구 논문집 Vol.16 No.2

Five kinds of Korean red pepper-pinkish, perfect, cucumber, blue, and ground cherry-were used, respectively, to analyze the contents of Capsaicin and Dihydrocapsaicin. The comparative analysis was performed separately in the seed removed red pepper and the seed included red pepper by HPLC. Among the seed removed pepper, the results for the content of Capsaicin were shown as follows: ground cherry(2204.0ppm) > pinkish(1324.9ppm) > blue(906.7ppm) > cucumber (77.2ppm) > perfect(12.9ppm), and the results for the content of Dihydrocapsaicin were shown as follows: ground cherry (1004.8ppm) > pinkish(248.3ppm) > blue(165.7ppm) > cucumber(13.9ppm) > perfect(0.0ppm). Among the seed included red pepper, the results for the content of Capsaicin were shown as follows: ground cherry(2190.lppm) > pinkish(1324.4ppm) > blue (919.9ppm) > cucumber(79.5ppm) > perfect(11.7ppm), and the results for the content of Dihydrocapsaicin were shown as follows: ground cherry(1017.4ppm) > pinkish(270.6ppm) > blue(189.0ppm) > cucumber(39.4ppm) > perfect(0.0ppm). Overall results suggest that in the contents of Capsaicin and Dihydrocapsaicin, the seed removed pepper and the seed included red pepper both were decreased in the order of ground cherry > pinkish > blue > cucumber > perfect, and this order is proportional to the strength of hot taste of red pepper.

Background : The cun measurement System, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and Small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height.
