상황버섯박의 사료화에 관한 연구

장석훈,김성복,이봉덕,이수기 충남대학교 농업과학연구소 2008 농업과학연구 Vol.35 No.2

This experiment was conducted to investigate the feed value of Phellinus linteus meal. The chemical composition and particle size of Phellinus linteus meal was determined, and investigated the effect of partial substitution(0, 5, 10 and 20%) of dried Phellinus linteus meal on metabolizability and serum IgG concentration of layers. Crude fiber content of Phellinus linteus meal was higher, and crude protein and crude fat contents were similar level compare to corn, barley, and wheat. Dry matter metabolizability of Phellinus linteus meal was lower in 10 and 20% treatment than those of 0 and 5% treatment significantly(p<0.05). But, Phellinus linteus meal did not affect concentration of serum IgG. 본 시험은 상황버섯박의 사료가치를 조사하기 위하여 화학적 성분을 분석하고, 산란계를 이용하여 급여수준(급여사료의 0, 5, 10 및 20%)에 따른 대사율과 혈청 IgG 농도를 조사하였다. 영양적 조성에 있어서는 섬유질성 단미사료수준 이상의 영양소를 함유하고 있으며, 산란계에 대한 대사율은 대조구에 비하여 상황버섯박 10 및 20% 첨가구가 유의하게 낮은 결과를 보였다(p<0.05). 그리고 혈청 IgG 농도에 있어서는 첨가수준에 따른 유의적인 차이를 발견할 수없었다. 위 결과로 볼 때 상황버섯박은 섬유질 함량이 높아 단위 동물의 사료로는 제한적 사용이 불가피하며, 버섯의 약리성분은 추출잔류물이라는 특성으로 볼 때 그 작용을 기대하기는 어려울 것으로 판단된다. 또한 상황버섯박은 섬유질 함량이 높은 것으로 보아 단위 동물보다는 반추동물의 사료로 이용하는 것이 유리할 것으로 생각된다.

박창헌,황현식,이기헌,홍석진 대한치과교정학회 2004 대한치과교정학회지 Vol.34 No.4

고정식 교정장치를 부착한 경우 장치주위의 치태 축적 가능성이 증가되고 이로 인해 치은염, 법랑질 탈회 등의 부작용이 초래 될 수 있는 바 치태 제거를 위한 효과적인 치솔질이 필요하다. 본 연구는 교정환자에서 일반적으로 사용되고 있는 치솔에 비하여 전동치솔이 구강위생에 도움이 되는지 알아보기 위하여 시행되었다. 고정식 장치에 의한 교정치료 예정인 환자 34명을 본 연구의 대상으로 하여 고정식 교정장치 부착 전에 치태지수, 치은염지수, 치은출혈지수를 측정하였다. 장치 부착 4주 후에 각 지수를 측정한 다음, 연구대상을 치솔의 종류에 따라 전동치솔군과 수동치솔군으로 임의 구분하여 수동치솔 또는 전동치솔을 사용하도록 구강위생교육을 각각 시행하였다. 이때 전동치솔의 경우 본체는 Braun Oral-B D9511을 브러쉬 헤드는 Braun Oral-B Ortho OD 15-1을 사용하게 하였으며, 수동치솔의 경우는 Butler G.U.M 124를 사용하게 하였다. 구강위생교육 4주 및 8주 후에 각 지수를 측정한 다음 시간 경과에 따른 전동치솔군과 수동치솔군의 구강위생 상태를 비교 분석하여 다음과 같은 결과를 얻었다. 1. 고정식 교정장치 부착 4주 후 치태지수, 치은염지수, 치은출혈지수 모두 증가 양상을 나타내었다. 2. 구강위생교육 후 치태지수, 치은염지수, 치은출혈지수 모두 감소 양상을 나타내었다. 3. 치은염지수, 치은출혈지수의 경우 감소양상이 수동치솔과 전동치솔군 간의 유의한 차이를 보이지 않았다. 4. 치태지수의 경우 수동치솔에 비해 전동치솔군에서 감소효과가 유의하게 크게 나타났다. 이상의 연구 결과는 고정식 교정장치로 치료받는 환자에서 전동치솔이 구강위생에 도움이 됨을 시사하였다. Patients with fixed orthodontic appliances frequently have increased levels of plaque accumulation leading to the possibility of gingivitis or enamel decalcification. Although many methods may be helpful in reducing dental plaque formation, the optimal mechanical removal of plaque is the most important factor during orthodontic treatment. The purpose of this study was to evaluate the efficacy of an electric toothbrush (with a specially designed orthodontic brush head) compared to a manual toothbrush in controlling plaque and gingivitis for patients with fixed orthodontic appliances. Oral hygiene status was measured in thirty-four patients using a plaque index, a gingival index and a bleeding index, before and four weeks after the attachment of fixed orthodontic appliances. Patients were randomly divided into two groups: electric and manual toothbrush groups. Oral hygiene instruction was given according to the type of toothbrush used. The Braun Oral-B D9511 with Braun Oral-B Ortho OD 15-1 brush head was used as the electric toothbrush while the Butler G.U.M. 124 was given as the manual toothbrush. After four and eight weeks, oral hygiene status was measured again. Through a comparison between the electric and the manual toothbrush groups, the following results were obtained. 1. All oral hygiene indices showed an increasing tendency after four weeks of fixed orthodontic appliance. 2. All indices presented a decreasing tendency four and eight weeks after oral hygiene instruction. 3. In case of the gingival index and bleeding index, the decreasing tendency did not show a statistically significant difference between the electric and the manual toothbrush groups. 4. The decreasing tendency of plaque index presented a statistically significant difference between the two groups, showing that the electric toothbrush was more effective in terms of oral hygiene. These findings suggest that an electric toothbrush is useful to orthodontic patients with fixed appliances.

姜錫憲,金映辰 大韓神經精神醫學會 1982 신경정신의학 Vol.21 No.2

The purpose of this study is to delineate some clinical characteristics of post-traumatic or accident neuroses; family and economical back ground, clinical symptomatology and diagnosis, and problems surrounding compensation. The authors collected the clinical records of 99 post-traumatic psychiatric inpatients and outpatients at Kyungpook and Kyemyung University Hospitals and three other private psychiatric clinics at Daegu area, during a period of two years from January 1st, 1979 to December 31, 1980. Out of the 99 post-traumatic cases, 19 cases with organic brain syndromes were excluded in the present study. Of all the 80 cases, 38 cases were interviewed by the authors and 42 by other psychiatrists. The results obtained could be summarized as follows; Of all the 80 post-traumatic cases, the number of male patients was 51 and that of female was 29, the male to female sex ratio being 1.8:1. Slightly over half of them were in their thirties and forties. The educational level of about two thirds of the patients was below middle school. 16% of them were unemployed, and 25% laborers. And majority of them belonged to low social classes. In the psychiatric interview, they showed a variety of difficulties; financial difficulties (25%), interpersonal conflicts (18%), vocational dissatisfaction (9%), and other physical illnesses (4%). Most frequent symptoms of the post-traumatic neurotics were headache (78%), insomnia (43%), dizziness (34%), memory loss (29%), anxiety (25%) and loss of interest (25%). As to the clinical diagnostic classification (ICD-9), 55% was diagnosed as hysteria, 19% as anxiety neurosis, 14% as neurotic depression, 6% as hypochondriasis and 2% as phobic neurosis. The average period of hospitalization was 50.3 days, and the duration from the time of trauma to the first psychiatric visit was 35.5 days in average. Finally, the authors had the impression that the course of post-traumatic neuroses was much influenced by the attitudes of the offenders and the court process of the compensation itself.

姜錫憲 慶北大學校 醫科大學 1980 慶北醫大誌 Vol.21 No.2

The purpose of this paper is to describe an approach of a short term child psychiatry unit. The paper gives a brief literature riview of milieu therapy, therapeutic community, and children's psychiatric hospitals. Secondly a historical review of the philosophy and structure of the Child Psychiatry Unit at the Mount Sinai Medical Center, New York City, and thirdly, a description of some of the principles which form the basis for the practices on this ward. In conclusion, the author stressed the difference between the milieu therapy of the Child Psychiatry Unit of the Mount sinal Medical Center and that modelled along a developmental/educational paradigm. The therapeutic techniques of the ward varies including ego supportive and ego interpretive methods. The therapeutic activities program of the ward provides for each child to develop his cognitive and social skills. The nursing staff supports the child, helps his social skills and provides for new models of identification. In addition, the method of ego interpretation is a valuable tool that even in a short term treatment provides for ego development and progression by enabling the child to gain some insight and control over some of his instinctual urges.
