This study was conducted to prepare canned skipjack tuna Katsuwonus pelamis in the mixture of isotonic beverage and tomato paste (ST-S) for use as a health food. An analysis of the time-temperature profile and viable cells showed that a reasonable F0 value for ST-S preparation was 4 min. The proximate composition of ST-S was 76.8% moisture, 20.2% crude protein, 0.8% crude lipid, 1.7% ash and 0.5% carbohydrate. The calorie content of ST-S was 94.8 kcal, which is 47.4% lower than that of commercial canned skipjack tuna in oil (ST-O) and 2.2% lower than that of commercial chicken breast in water (CB-B). The total amino acid content of ST-S was 18.54 g/100 g, which is 31.4% lower than that of ST-O and 7.9% lower than that of CB-B. The major amino acids in ST-S were aspartic acid and glutamic acid. An enrichment effect due to such minerals as phosphorus, potassium and iron would be expected on consuming 100 g of ST-S. The major fatty acids in ST-S were 16:0 (27.4%), 18:1n-9 (14.3%) and 22:6n-3 (27.8%), which are different from those in ST-O and CB-B. The major free amino acids in ST-S were glutamic acid (8.1%), histidine (38.6%) and its related dipeptide, such as anserine (15.7%). In an evaluation of taste, flavor and color, ST-S was found to be superior to ST-O and CB-B.

시금치에 fumaric acid와 mild heat의 병합처리를 통해 병원성 미생물 제어효과를 규명하고자 시금치에 E. coli O157:H7, L. mon℃ytogenes 를 접종한 후 각 단일처리 후 미생물 수 변화를 측정하였다. Fumaric acid (0.1, 0.3, 0.5%)와 mild heat (40, 50, 60℃)의 각 단일처리 실험 결과를 토대로, 병합처리를 위한 fumaric acid의 최적농도는 0.5%, mild heat 처리조건으로 50℃ 에서 5 min으로 선정하였고, 병합처리 시 L. mon℃ytogenes, E. coli O157:H7의 수는 대조구에 비해 각각 2.53, 2.62 log CFU/g 감소하였다. 그리고 신선한 시금치에 병합처리 후 4℃에서 12일간 저장하면서 미생물 수 감소 및 품질 변화를 조사하였다. 시금치의 초기 미생물 수에 있어서 대조구와 비교하여, 병합 처리구에서 총 호기성 균을 2.77 log CFU/g 감소시켰다. 특히, 저장 12일 후 병합 처리구의 총 호기성 균 수는 4.84 log CFU/g으로 대조구와 비교하여 1.82 log CFU/g의 감균 효과를 가졌다. 또한 시금치의 저장 중 Hunter 색도 값 및 비타민 C 함량에 있어서 처리구 간의 유의적인 차이를 보이지 않았다. 따라서 본 연구 결과, fumaric acid와 mild heat의 병합처리가 시금치의 미생물학적 안전성 유지에 효과적인 처리라고 판단된다. The objective of this study was to examine the combined effect of fumaric acid with mild heat on the inactivation of microorganisms on spinach. Spinach leaves were in℃ulated with Escherichia coli O157:H7 and Listeria mon℃ytogenes. Based on the results of single treatment of fumaric acid (0.1, 0.3, and 0.5%) or mild heat (40, 50, and 60℃) regarding the inactivation of the in℃ulated bacteria, the optimal condition for the combined treatment was suggested to be 0.5% fumaric acid and mild heat treatment at 50℃ for 5 min. The combined treatment of fumaric acid with mild heat caused 2.53 and 2.62 log reductions of the populations of L. mon℃ytogenes and E. coli O157:H7, respectively. In addition, during storage of fresh spinach at 4℃ for 12 d, the combined treatment reduced initially the populations of total aerobic bacteria by 2.77 log CFU/g compared with the control. In particular, after 12 d of storage, the population of total aerobic bacteria for the combined treatment sample was 4.84 log CFU/g, whereas the control sample had 6.66 log CFU/g. Color and vitamin C content of spinach samples were not altered significantly by the combined treatment during storage. These results indicate that the combined treatment of fumaric acid with mild heat is an effective method to control microorganisms on spinach during storage.

Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

Various surgical approaches to the orbits have been used. But the transconjunctival approach, also called the inferior fornix incision, provides adequate access to the orbital floor with esthetic results. Additionally, transconjunctival approach with lateral canthotomy allows more wide surgical field and good access to the orbital area. Generally, preseptal approach is more used rather than postseptal approach in the transconjunctival incision for the prevention of fat herniation during surgery. There are some complications in transconjunctival approaches but these complications can be prevented with careful surgical techniques. We report clinical results in 12 patients who were treated by preseptal transconjunctival incision with lateral canthotomoy for the treatment of orbital trauma. We were satisfied with this technique for reduction and reconstruction of the orbital trauma and we could also observe relatively good esthetic results.

염민호,김영록,김현정 韓國敎員大學校 敎育硏究院 2009 敎員敎育 Vol.25 No.3

이 연구의 목적은 대학 글쓰기 교육의 성공적 요인으로 중시하는 '글쓰기 교과 교수 개발 프로그램’의 내용과 효과를 경험적으로 분석하여, '글쓰기 교과 교수 개발 프로그램’의 발전 방안을 모색하는데 있다. 전남대학교에서 지난 4년 동안(2005-2008) 개발하여 운영한 교수 개발 프로그램의 내용 분석 결과,글쓰기 교과 교수 개발 프로그램의 유형은 '글쓰기 강사 워크숍', '특별 연수 프로그램’,'더 나은 가르침을 위한 교수공동체’ 등으로 세분화되어 있었다. '글쓰기 강사 워크숍'의 주제는 교재 분석,강의안 개발,피드백 사례 공유 등이었다. '글쓰기 강사 워크숍'의 효과 분석을 위해 9차 워크숍에 참여한 43명의 강사들을 대상으로 한 설문 분석 결과, 워크숍은 실제 강의에 도움이 되며,워크숍에 많이 참석한 강사들이 적게 참석한 강사돌보다 강의에 어려움을 덜 겪는 것으로 나타났다. 결론에서는 교과 개선을 위한 교수 개발프로그램 개발 및운영과 관련하여 유념해야 사항을 ‘프로그램 목적의 명료화’,'워크숍 참여의 의무화’ '평가의 중요성’ 등 세 가지로 나눠 논의했다. This study analyzes the contents and effectiveness of a faculty development program and suggests ways to improve university writing courses. Through a content analysis the study explored a faculty development program developed and operated since 2005 at Chonnam National University, South Korea. The study revealed that the program included a specialized writing workshop for instructors and in-service training for beginning instructors, which led to the betterment of the teaching community. Major aspects of the program included the analysis of textbook, the development of lecture plans and the sharing of feedback. Employing a questionnaire divided into pre- and post tests, the authors examined the perceptions of 43 instructors who took part in the ninth workshop of the program. The results revealed that the participants generally recognized the positive effects of the workshop. Instructors who participated in several workshops found less difficulty in their own teaching compared with instructors who did not have multiple workshop experience. The authors discuss points from this study and offer suggestions on how to improve faculty development programs for specific subjects, including the importance of goal setting in the programs, the development of mandatory workshop programs, and the importance of appropriate evaluation.

안면비대칭 환자의 진단 및 치료계획 수립 시 하악골 상행지 고경의 좌우 차이를 정확히 판정하는 것이 필요하다. 본 연구는 2차원 방사선사진에서 정면 상행지경사도 및 측면 상행지경사도를 이용하여 하악골 상행지 고경을 보정하는 방법이 비대칭 판정에 도움이 되는지 알아보고자 시행되었다. 이부 편위가 있는 안면비대칭자 40명을 대상으로 정모두부방사선규격사진을 촬영하고 좌우 각각의 하악골 상행지 고경을 측정하는 한편 정모 및 측모 방사선사진에서 계측된 정면 상행지 경사도 및 측면 상행지 경사도를 이용하여 상행지 고경을 3차원적 개념으로 보정한 후, 실제 3차원 영상에서의 비대칭 판정 결과와 비교 분석을 시행하였다. 측정결과, 정면 및 측면 상행지 경사도는 이부편위측에 비하여 반대측에서 크게 나타났으며 보정 후 상행지 고경의 좌우 차이는 증가하는 양상을 나타내었다. 보정 전 그리고 보정 후 각각에서 상행지 고경의 좌우비대칭 여부를 판정한 후, 3차원 영상에서의 판정을 기준으로 하여 보정에 따른 sensitivity, specificity 그리고 accuracy 변화를 살펴본 결과, specificity는 44%에서 22%로 감소하였으나 sensitivity는 74%에서 94%로 증가하는 것으로 나타났다. 아울러 accuracy가 보정 전 68%에서 보정 후 78%로 증가하는 것으로 나타나 정면 및 측면 상행지 경사도를 이용하여 상행지 고경을 3차원적 개념으로 보정할 경우, 이는 보다 정확한 비대칭 판정에 유용함을 보여주었다. Objective: Defining right and left side differences in mandibular ramus height is one of the key elements in the diagnosis of facial asymmetry. The purpose of the present study was to evaluate the effect of correction of ramus height with frontal and lateral ramal inclinations (FRI and LRI) in 2-dimensional cephalograms and observe how this affects the diagnostic accuracy of asymmetry. Methods: Frontal and lateral cephalograms were obtained in 40 individuals with chin deviation. FRI and LRI were measured on each side and ramus height measurement was corrected with these inclinations using Pythagorean's theorem. The results of diagnosis before and after correction on cephalograms were compared with the results in 3D CT images. Results: Both FRI and LRI showed greater values in the contralateral side than in the chin-deviated side and these contributed to an increase in the right and left side ramus height differences. After comparison of diagnostic results before and after correction on cephalograms with the results on 3D CT images, the sensitivity increased significantly (from 74 to 94 %) whereas the specificity decreased (from 44 to 22 %). Overall accuracy increased from 68 to 78% with the correction using FRI and LRI. Conclusions: The results of the present study indicate that correction of ramus height with FRI and LRI is useful for an accurate diagnosis of facial asymmetry on frontal cephalograms.

An increasing number of genome sequencing projects results in explosive growth of whole genome sequences. Furthermore the number of studies on the functions of individual genes has also been rapidly increased. However on-memory algorithms are not applicable to the analysis of whole genome sequences, since the size of individual whole gene a ranges from several million base pairs to hundreds billion base pairs. In order to effectively manipulate the huge sequence data, it is necessary to use the indexed data structure for external memory. In this paper, we introduce the development and application of the workbench for the analysis and visualization of whole genome sequences using string B-tree that is suitable for the analysis of huge data. This system consists of two main parts, the analysis query part and the visualization part. The query system supports various transactions such as pattern matching, k-occurrence, and k-mer analysis. The visualization system helps biologists to easily understand whole genome structure and specificity by various kinds of visualization such as whole genome sequence viewer, annotation viewer, CGR (Chaos Game Representation) viewer, k-mer viewer, RWP (Random Walk Plot) viewer, and map viewer. We can find the relationships among organisms, support gene prediction in a genome, and study the function of junk DNA using our workbench. In this paper, we apply our workbench to investigating specific sequence such as avoided sequence, common sequence, and classifiable sequence.

The "Sound Classification System on Floor Impact Sound Insulation Performance" is being studied in Korea. For that study, vocabularies appropriate for evaluation and reporting are needed. In this study, adequate words for evaluating floor impact sound have been extracted by reviewing the existing vocabularies and augmenting this with the results of a questionnaire prepared especially for apartment dwellers. As a result of this study, followings are suggested. 1) The heavy impact sound sources are more highly ranked than light impact ones. And the louder sound sources are the more accumulated points. 2) Highly ranked vocabularies are different for each source. 3) Floor impact sound evaluating words such as ‘Annoying’, ‘Disagreeable’, ‘Strident’, ‘Disturbed’, and ‘Dissonant’ are highly ranked. ‘Annoying’ is the word most accurately expressing the subjects' unpleasant feeling of domestic floor impact noise. 4)‘Unpleasant’, ‘Noisy’, ‘Irritating’, ‘Annoying’ are main unpleasant factors to floor impact sounds occurring in our domestic apartment houses.

Objects : Prior reviews have indicated that antipsychotic drugs may impair planning ability and memory but otherwise may even improve attention and reaction time performance. This study was performed to evaluate the effect of clozapine on cognitive functions and psychopathology in chronic schizophrenic patients. Methods : Neuropsychological tests such as Wisconsin Card Sorting test, Digit Span test and Judgment of Line Orientation test were applied to 21 chronic schizophrenic patients and 15 normal controls. The schizophrenic patients were retested with the same instruments after 3 monthes of treatment period with clozapine. Psychopathology was assessed in the same patients before initiation of clozapine and at 12 weeks using BPRS. Results : Cognitive impairment was found in each measure of executive function, attention, short-term memory and visual perception ability as compared with the normal controls. After 12 weeks of clozapine treatment, signigicant improvement occured in attention, short-term memory and visual perception ability as well as psychotic symptoms including both positive and negative symptoms, but had little effect on executive functions. Conclusion : Short-term treatment with clozapine may possibly improve parts of cognitive functions of chronic schizophrenics, and these effects can contribute to increase capacity for work and social function.
