  • 최근 doctor fish(Gara rufa obtusa)를 이용한 Ichthyotherapy는 인간 피부질환의 대체 치료법으로 각광받고 있으며, 근래 doctor fish의 국내 증식 성공으로 인하여 이러한 추세는 증가되고 있다. 그러나 doctor fish의 질병과 생태에 대해서는 아직 연구가 미미한 실정이다. 본 보고는 국내에서 증식되던 doctor fish가 Citrobacter freundii에 감염되어 집단 폐사한 예로서, 병어에 대한 외부 및 내부 진단, 분리된 세균의 형태학적, 생화학적 동정을 통하여 C. freundii를 확정하였으며, 분리된 C. freundii에 대한 항생제 감수성 검사를 수행하였다. 또한 살아남은 병어에 대한 집단 치료를 시도하여 성공적인 치료 효과를 얻을 수 있었다.

  • Since April 2012, doctor fish in the breeding tank and in the quarantine tank in Hanwha Aquaplanet Yeosu Aquarium have been dying, accompanied by diffuse bleeding around the mouth, in the chin, and at the bottom of the abdomen. In this study, the cause of death would be examined through the bacteriological study of doctor fish and the rearing water quality in the aquarium. The water quality and the bacterial counts of the rearing water in the exhibit tank and in the quarantine tank were analyzed once a week, starting from August to November 2014. Water quality was measured based on the following data: temperature was in the range of 24.5~26.8℃, pH at 6.77~7.94, DO at 6.15~8.61 ppm, ammonia at 0~0.93 ppm, nitrite at 0.009~0.075 ppm, and nitrate at 1.1~40.9 ppm. Studies revealed that the differences in these water quality factors were not related to the death of doctor fish. Bacterial counts in the rearing waters of Garra rufa slightly increased to 103~104 CFU/ml, just before the death of the doctor fish. Twelve strains of bacteria were isolated from the dead fish and rearing waters. The isolates were identified as Aeromonas veronii, Citrobacter freundii, Pseudorhodoferax aquiterrae, Shewanella putrefaciens, and Vibrio anguillarum on the basis of 16S rRNA gene sequences. The most dominant species was C. freundii, which showed medium sensitivity to florfenicol and norfloxacin, and was resistant to amoxacillin, doxycycline, oxytetracycline, tetracycline, and trimethoprim. Ten isolates were confirmed to be pathogenic to the doctor fish. Doctor fish infected with C. freundii and S. putrefaciens showed high mortality in the experimental groups. These results indicate that the variation in bacterial numbers in the rearing water was related to the death of doctor fish. C. freundii and S. putrefaciens were directly implicated in causing the death of doctor fish in the aquarium.

  • 단(單)원통형 및 원통형 드럼건조기를 이용하여 잘게 저민 생선으로부터 플레이크를 성공적으로 만들 수 있었다. 생선의 높은 지방함량으로 인해 저민 생선이 드럼에 잘 들러붙지 않는 문제점은 타피오카가루의 형태로 2.5%의 전분을 저민 생선에 첨가함으로서 건조양상에는 영향을 미치지 않으면서 해결될 수 있었다. 제품의 수분함량을 일정한 수준으로 유지할 경우 건고형분(乾固形分)의 생산속도는 드럼간의 간격을 최소로 줄였을때 최고에 도달하였다. 건고형분(乾固形分)의 생산속도는 드럼의 회전속도가 증가할수록 선형적으로 증가하였고 제품의 품질이 손상되지 않는 범위에서 스팀의 압력이 높을수록 증가하였다. 총괄 열전달계수는 드럼의 회전수가 증가함에 따라 증가한 반면에 드럼간의 간격이 커짐에 따라 증가하지는 않았다. $MR\;=\;A\;\exp(\;-k{\theta})$로 표시되는 가장 보편적인 건조 모델식이 드럼건조에도 적용될 수 있었다.

  • Compare western medicine report and books which refer to Gout with Oriental medicine books which refer to Tongp'ung(痛風). The results of studying about Gout and Tongp'ung(痛風) were summarized as follows. l. Dangyesimbub(丹溪心法) was printed in 1481 and also the first book which referred to Tongp'ung(痛風). 2. Donwonsipjonguiso(東垣十種醫書) was printed in 1592 and also Tongp'ung(痛風) was recorded like gout especially in cause of disease. 3. Ancient times, Affection by exopathogen and six kinds of natural factors were persisted the cause of Tongpung(痛風), later generation drink, diet and labor were persisted. 4. In Beunjungrok(辨證錄) and susyebowon(壽世保元), there were similar expressions about gout, for examples interval phase and chornic tophaceous. 5. In Uihakjongjon(醫學正傳) and Manbeunghoechun(萬病回春) insisted that gout patients had to control their food especially meat, fish snd drink. 6. According to the cause(Pung(風), Han(寒), Sub(濕)), doctor classified Bi(痺) first was Hangbi(行痺), second was Tongbi(痛痺) and last was Chakbi(着痺). 7. Doctors thought that Tongp'ung(痛風,) was not Hangbi(行痺) and Chakbi(着痺) but it was Tongbi (痛痺). Especially in pain, they thought it was similar to Bakhoyeukjolp'ung(白虎歷節風).

  • 목적: 40세 이상의 한국 성인 남녀에서 녹내장 발병과 식사패턴과의 관련성을 알아보고자 하였다. 방법: 국민건강영양조사 자료를 이용하여 40세 이상의 성인남녀 총 6,453명(남자 2,759명, 여자 3,694명)을 대상으로 하였다. 녹내장은 의사로부터 진단받았던 경우를 기준으로 하였다. 일차적으로 녹내장과 비만지수와 관련성을 확인하기 위해서 녹내장과 정상군에서 허리둘레와 체질량지수를 비교하였다. 두 번째로 등푸른 생선(고등어), 해조류(김, 미역), 콩류(콩류, 두유), 야채(시금치, 콩나물, 오이, 당근, 양배추, 고추, 토마토, 호박), 과일(귤, 사과, 딸기, 배, 포도, 복숭아)에 대해서 요인분석을 이용하여 식사패턴을 분석하였다. 마지막으로 추출된 식사패턴요인과 녹내장과의 회귀분석을 실시하였다. 결과: 녹내장과 정상군에서 허리둘레와 체질량지수는 각각 $82.25{\pm}9.96cm$$23.27{\pm}2.84kg/m^2$, 그리고 $75.79{\pm}13.79cm$$22.39{\pm}4.0kg/m^2$로 유의한 차이를 확인할 수 있었다(p<0.05). 요인분석에 의해 조사된 섭취식품은 총3개의 요인으로 추출되었으며, 이때의 요인 1은 콩나물, 시금치, 당근, 양배추, 미역, 오이, 고등어, 김으로 묶여졌다. 식사패턴요인 1은 녹내장의 발병 위험도를 줄이는 경향을 보였고(OR: 0.697, 95%CI: 0.496-0.980, p=0.038), 성별과 연령을 보정한 후에도(OR: 0.698, 95%CI: 0.497-0.982, p=0.039) 마찬가지로 나타났다. 결론: 한국성인을 대상으로 녹내장과 식사패턴요인과의 관련성을 처음 분석한 연구로서 야채, 김과 고등어는 녹내장의 위험도를 감소시키는 관계가 있었다.

  • In the process of devising an efficient meal service system for the elderly, 478 elderly were interviewed at 6 different social centers with the elderly meal service program in Seoul area to monitor degree of satisfaction and/or needs of the beneficiaries regarding the program. The survey was conducted during the month of December 2002 by well-trained interviewers using self-developed questionnaire. Results were analyzed statistically using SAS package program. Most of the beneficiaries were low economic class and 76% of them had doctor diagnosed disease(s). Among the beneficiaries of congregate meal service, mean score of 12 aspects of satisfaction was 3.72 out of 5. For most of the questions, female elderly and healthy elderly responded with higher score than male elderly and unhealthy elderly, respectively (p<0.05, p<0.01). On the other hand, beneficiaries of the home-delivered meal service were little bit less satisfied with the service (3.54 out of 5). Compared to the beneficiaries of congregate meal service, larger portion of beneficiaries of home-delivered meal service wanted more meats (28.5 % vs. 17.1 %) and vegetables (23.2 % vs. 12.3 %) as side dishes. On the other hand, the most preferred type of cooking and/or seasoning was stewing for both cases. Based on these findings, it is suggested that more fresh foods should be used than processed foods in the preparation of meals for the elderly and, more fish-, meat- and vegetable- dishes should be served to come up to the needs of the elderly. Onto this, mainly Korean style meals with some intermittent Western, Japanese or Chinese style meals served at the right temperature would suffice most of the elderly needs.
