In this study, dilute acid pretreatment of Liriodendron tulipifera was performed for enzymatic hydrolysis. As the pretreatment temperature was increased, enzymatic hydrolysis and enzyme adsorption yield also increased. The highest enzymatic hydrolysis yield was 57% (gig) and enzyme adsorption was 44% (gig). Enzymatic hydrolysis yield was determined with weight loss of pretreated biomass by enzyme, and enzyme adsorption was a percentage of enzyme weight attaching on pretreated biomass compared with input enzyme weight. When L. tulipifera was pretreated with 1% sulfuric acid at 160℃ for 5 min., hemi-cellulose was significantly removed in pretreatment, but the lignin contents were constant. Other changes in surface morphology were detected on biomass pretreated at 160℃ by a field emission scanning electron microscope (FESEM). A large number of spherical shapes known as lignin droplets were observed over the entire biomass surface after pretreatment. Hemicellulose removal and morphological changes improved enzyme accessibility to cellulose by increasing cellulose exposure to enzyme. It is thus evidence that enzyme adsorption is a significant factor to understand pretreatment effectiveness.

This study has been carried out to investigate pathogenesis, symptoms, treatment method of Climacteric Hindrance. The results were obtained as follows ; 1. In oriental medicine, Oimacteric Hindrance is caused by exhaustion of chungye(天癸), discordance of internal organs, discordance of the roles of yin and yang in kidney and its pathogenesis are the deficiency of Qi of the kidney and the depression of liver energy. In western medicine, the decline of ovary function is regarded as Climacteric Hindrance's pathogenesis. 2. The symptoms of Climacteric Hindrance are divided into the whole body's symptoms(psychogenic symptom) and partial symptoms(menstruation hindrance). 3. The medical treatments of Climacteric Hindrance are medicine treatment, acupuncture and psychologic therapy. And the treatment method of Climacteric Hindrance are aliment liver and kidney, aliment um(陰) and blood, making mental comfort, aliment um(陰) and controlling fire, softening liver energy. 4. The symptoms of Climacteric Hindrance are different one another, so many treatment methods can be required.

Supra Pubic Catheter를 施行한 腦卒中 患者 1例에 對한 證例報告
유병찬,오병렬,김민상,안정조,임승민,최영,설인찬 대전대학교 한방병원 2002 惠和醫學 Vol.11 No.1
According to the literary study on catheterization of bladder in one case of patient with C.V.A. who was treated by supra pubic catheterization, the results were as follows. 1. If not immediately treat ischuria, emergency disease, very great danger to life can happen by loss of kidney function. So we must treat ischuria instantly by consideration of treatment from the factor. 2. Catheterization of bladder generally acted in emergency room, is emergency treatment only in the lower part of urethral obstruction. 3. Catheterization of bladder was put on record in Son Saimiao's Qianjinyaofang, which is the first book on it. It had been developed by Luo Qianyi, Zhang Jiepin, and Wang Dao. 4. Ancient times, an urethral catheter was made of green onion leaf, pig bladder, goose feather and so on. 5. Nelaton is catheterization of bladder in functional or momentary ischuria. Indwelling catheterization is treatment keeping in urethral canal for a long time. 6. Supra pubic catheterization is a surgical operating catheterization when urethral catheterization is impossible, is very easy and can decrease risk of infection. 7. After catheterization, for decreasing risk of the infection, a complication of catheterization, it is must be taken precedence, ascetic treatment, constantly management and sterilization, anti-biotic medication. 8. At times, increasing patient of emergency disease, as C.V.A etc., the needing of catheterization of bladder is increasing also for preventing infection and bed sore by ischuria and incontinence of urine. Therefore a specialty knowledge and skill about it is necessary.

The purpose of this study was to analyze the professionalism of elementary school teachers and to draw out factors which elementary teachers should try to improve their professionalism for environmental education. For the study, both Quantitative analysis and qualitative methodologies were applied: First, randomly selected 483 elementary teachers from Seoul and Gyeonggi self responded to 5 evaluation areas by Hungerford et al. (1994) to evaluate their environmental education professionalism through the use of five point Likert scale. Second, 2 elementary teachers' environmental classes were observed for the purpose of analyzing strengths and weaknesses in classroom instruction, and then the results of self-evaluation on environmental education professionalism and teacher professionalism as shown in the classes were compared. It was found that 483 elementary teachers including 2 teachers for analyzing classroom instruction who performed a self-evaluation gave themselves mid-scores on the Hungerford et al.'s 5 evaluation areas. However, the result of self-evaluation did not correspond with the result of actual class observation and teacher interview. That is, the actual environmental classes conducted by 2 teachers did not seemed to reflect the evaluation areas which were the foundation of the study: the conceptual awareness, the investigation & evaluation, environmental action skills, and educational application. The results of this study can be used as the basis reference to develop teaching-learning program and in-service programs for professional development of teachers for successful application of environmental education in elementary school classes.

Objectives: In order to establish prevalence and characteristics of tinnitus and hearing thresholes according to tinnitus, this study was carried out. Methods: Nine hundred and thirty two subjects, undergone human dock or general health check-up and been in college, were surveyed to the questionnaire on the general characteristics, past medical histories, life styles, subjective symptoms about hearing, taking ototoxic drugs and were conducted on the hearing thresholds by pure tone audiometry. Results: Of the total population, 98 reported tinnitus, giving an overall prevalence of 10.5%, prevalence of tinnitus in the subjects with the factors influencing hearing thresholds were 17.4%, prevalence without the factors influencing hearing thresholds were 7.5%. Frequency of tinnitus of the total population was the highest in 'once per several months' (39.6%) and followed by 'once per several days'(29.7%), 'all day long' (16.5%) and 'several times per day' (14.3%). Complaint site of tinnitus was 41.8% in left ear or right ear, 39.6% in both ear and 18.7% in head. The 13.6% of the total subjects complained sleep disturbance. Hearing thresholds in the subjects without the factors influencing hearing thresholds tended to increase or decrease in 20 and 30 years old according to tinnitus, but those with tinnitus tended to increase more than those without tinnitus in 40 and 50 years old. Conclusions: Results also provide evidence that reports of tinnitus at the time of annual audiometric testing may be useful in identifying workers at greater risk for developing significant shifts in hearing thresholds. Awareness of the possible occurrence of tinnitus may encourage workers to cooperate more actively in a company hearing conservation programme.

광주지역 HIV/AIDS, 매독 혈청 양성률 및 임질 양성률 분포조사(2002-2006)
기혜영,최병선,서진종,김선희,김민지,김은선,박종태,정재근 대한감염학회 2009 감염과 화학요법 Vol.41 No.4
Background : The epidemic of human immunodeficiency virus (HIV) or sexually transmitted infections (STIs) is an important public health issue in the worldwide. Therefore, we investigated the trends of the seroprevalence of HIV and, syphilis and the gonorrhea positive rates in Gwangju from 2002 to 2006. Materials and Methods : The results of laboratory tests for HIV, syphilis and gonorrhea were collected from five public health centers and 19 hospitals in Gwangju. The number of tested patients from 2002 to 2006 was 348,202 cases for HIV, 80,115 cases for syphilis and, 103,548 cases for gonorrhea. Results : HIV/AIDS infections have rapidly increased at public health centers and hospitals. Especially, most of newly HIV-infected people were patients on ambulatory care/hospitalization, and they were also found via preoperation tests and according to the clinical symptoms. The gonorrhea positive rates have gradually decreased by year while the syphilis infection rates have slightly increased from 2002 to 2006. Conclusions : We have to determine the reasons why HIV and syphilis infections, but not gonorrhea, have increases simultaneously by the year. These results should be helpful to create a more effective STD prevention policy and the treatment guidelines for the people in Gwangju in the near future.
