Fatigue is the decline in force produced as a result of prolonged muscle activity. Localized muscle fatigue can be identified by a shift toward low in the frequency components of the EMG signal, typically represented by a fall in the median frequency. Previous studies show that a shortened muscle developes a higher fatigue than elongated muscles. The purpose of this study was to investigate the time-related change of median frequency and torque during maximal isometric back extension exercises at different exercise angles (0˚, 12˚, 36˚, 72˚). Twenty healthy subjects (mean age = 24.35 ± 2.70) were evaluated in this study. Median frequency was extracted from the EMG signals by fast Fourier transform (FFT). Initial median frequency and the slope of median frequency change over time were computed from linear regression analysis. Pearson's product moment correlation was used to quantify the relationship between scope of median frequency and torque. The results were as follows: 1) Significant differences in y-intercepts of torque regression equation with respect to exercise angle were shown. However, there were no differences in the slopes of the median frequency and torque, and y intercept of the median frequency among exercise angles. 2) There was no significant correlation between slope of median frequency and torque. 3) But there was moderate correlation between median frequency and torque at each exercise angle. In conclusion, the exercise angle during maximal isometric back extension exercise is not a direct effect on slope of median frequency and torque. But results showed that median frequency and torque shift were highly correlated in all subjects.

There have been so many researches about problems of cigarettes and relation of smoking and heath since 1950's and generally known that smoking is one of the worst factor of increasing disease and mortality. No matter what such many proofs about various problems of smoking have been researched, smoking rate of current male collage students has not been decreased. Besides, most of the researches about cigarette use and its addiction have been focused on the adolescent or adult women smokers or adult male, not male collage student. Therefore, the subject of this study is about smoking attitude and smoking behavior of male collage students by general features. Smoking attitude was analyzed by modifying 'Guidelines for the content of tobacco smoking surveys of the general population'(WHO, 1982). Two hundred of male collage students participated to the distributed questionnaire for one week in May. The smoking attitude was categorized into duration of smoking and number of cigarette per day(CPD), and nicotine dependency, investigated by Fagerstrom Tolerance Questionnaire(FTQ) (Fagerstorm & Schneider, 1989). All statistics were performed by procedure of SAS according to number, percentage, mean, standard deviation, and ANOVA. The results are as follows: 1. Smoking attitude level was mean 25.73±5.15 marks, ranging from 13 to 39 marks of the total 40 marks. 2. Duration of cigarettes, number of cigarette per day, and nicotine dependency were mean 5.14±2.84 years, 12.88±6.85 pieces, and 4.78±1.69, respectively. 3. Smoking attitude showed significance according to general features such as marital state and allowance, but the significance according to marital state is not valuable because the numerical difference is so big between married one and single that they cannot be compared with each other. 4. Duration of smoking was significant according to general features such as age and allowance. 5. Smoking amount showed significance the factors of age only. 6. ll1ere was no significance in nicotine dependency according to general features. As a result, smoking attitude of male collage student in this study shows moderate level. Smoking attitude and duration is significant according to allowance, and smoking amount is significant according to age. Nicotine dependency according to general features is not significant but comparing with the preceding study about adult male, male collage students in this study are respectively more nicotine-dependent than adult male smokers. In conclusion, the right allowance usage strategies and effective heath education focused on the young are needed. In addition, helpful programs and information spreading strategies are necessary for establishing higher level of smoking attitude. At last, systemic regulations in daily living for ""anti-nico-dependent"" and perspective reforming of male university student are needed for reducing nicotine dependency.

우리나라 재래종 벼 197품종과 생태형이 다른 자포니카 7품종, 인디카 3품종 및 통일형 5품종의 벼를 공시하여 각 품종의 이삭 특성을 밝히고 이들 형질간의 상관관계를 검토하였으며 특성에 따른 이삭형태의 분류를 실시하였다. 1. 재래종 벼 품종의 이삭 길이는 22.4 .05㎝, 현미의 천립중은 21.7 .35g로 자포니카와 비교하여 천립중은 같았으나 이삭 길이는 1.6㎝ 더 길었다. 2. 재래종 벼 품종의 1차지경 착생립수와 비율은 67.5 1.9립과 43.7 .14%이었고, 2차지경 착생립수와 비율은 91.2 0.7립과 56.3 .14%이었으며, 총립수는 158.1 5.8립으로 자포니카보다 44립 정도 더 많았다. 3. 재래종 벼 품종 현미의 장폭비는 1.70 .19로 자포니카와 유사하였으며 장립종도 몇 품종 존재하였다. 4. 1차지경 평균착생립수 각 절위별 2차지경수 및 2차지경 평균착생립수에 의한 재래종 벼 품종의 이삭형태를 분류한 결과 2차지경립 착생 하위우세형인 Ⅰ형에 2%, Ⅱ형에 10.7%, 중위우세형인 Ⅲ형에 67.5%, Ⅳ형에 18.3% 및 상위우세형인 Ⅴ형에 1.5%가 분포하였으며, 특히 1차지경 평균착생립수 5.1-5.5개의 Ⅲ형에 가장 많이 분포하였다. 5. 각 형질간의 상관관계에서 총립수와 2차지경 착생립수(0.921), 착립밀도와 평균 2차지경수(0.635)간에는 고도로 유의한 정의 상관이 인정되었다. The traits related to panicle are very important in improving the grain yield in cereals including rice. Characterization of panicle traits was conducted using 197 rice varieties of Korean landrace, 7 cultivars of Japonica, 3 cultivars of Indica and 5 cultivars of Tongil type to classify panicle types by distribution patterns of grains on panicle. In Korean landrace, average length of panicle and 1000-grains' weight of brown rice was 22.4±2.05㎝ and 21.7±2.35 g, respectively. Compare with Japonica. Iandrace was similar in 1000 grains' weight, but with a more longer panicle. Higher number of grains on each panicle (44 grains), was observed in landrace relative to the Japonica of rice. Panicle type was classified into five groups according to the number of grains on the primary rachis-branch, number of grain on the secondary rachis-branch and number of the secondary rachis-branches. According to panicle type based on distribution of grains, landrace was classified into five types. Most of the landrace grouped into panicle type Ⅲ, which is characterized as having many grains on the secondary rachis-branch in the middle position of panicle. Especially, frequency of panicle type Ⅲ which have 5.1-5.5 grains on the primary rachis-branch was higher than any other panicle type. In the case of correlation coefficient among panicle traits, highly positive significant correlations were observed in number of grain per panicle versus number of grains on the secondary rachis-branch(0.921) and in density of grain per unit panicle length versus number of secondary rachis-branch(0.635)

김경희,김종수,김승오 대한소아치과학회 2007 大韓小兒齒科學會誌 Vol.34 No.2

소아치과에서 진정요법은 chloral hydrate와 hydroxyzine을 함께 경구투여하는 방법이 가장 보편적이고, 진정의 심도가 술자가 원하는 정도에 미치지 못할 때에는 midazolam이나 N_(2)O/O_(2)를 병용투여하는 경우가 종종 있다. 본 연구는 chloral hydrate와 hydroxyzine을 이용한 진정요법의 효과와 안전성을 평가하고, 경구투여만으로 적절한 진정 수준을 얻지 못하여 N_(2)O/O_(2)를 병용투여한 경우, N_(2)O/O_(2)의 치료시간과 부작용에 대한 영향 그리고, 진정요법 효과에 영향을 줄 수 있는 변수들(연령, 성별, 체중, patient compliance, waiting time 등)을 확인할 목적으로 시행하였다. 2004년 12월부터 2005년 9월까지 단국대학교 치과병원 소아치과에서 chloral hydrate와 hydroxyzine을 이용하여 진정요법하에 치료받은 평균연령 30±8개월(12-51개월), 체중 13±2kg(9.5-18kg)의 총 94명(남아-46명, 여아-48명)의 환아들을 대상으로 조사하였다. 진정요법의 효과, 체중, 연령, 병용투여 방법에 따라 군을 분류하여 성별, 연령, 체중, patient compliance, waiting time, 치료시간, 치료양(RBVU), 부작용 등을 평가하였다. 진정요법 성공률은 85%였다. 진정요법에 성공한 그룹이 실패한 그룹보다 N_(2)O/O_(2)로 수면을 유도하여 사용하는 경우가 많았고, 치료시간이 길었다. 36개월, 14kg미만인 환아는 경구투여만으로 수면에 이를 수 있었고, waiting time이 짧았다. 36개월 이상인 환아는 N_(2)O/O_(2)를 사용하여 수면을 유도하는 경우가 많았다. 연령과 N_(2)O/O_(2)사용시간, N_(2)O/O_(2)사용과 치료시간사이에는 상관관계가 존재한 반면, 체중과 N_(2)O/O_(2)사용시간사이에는 상관관계가 없었다. 치료시간 연장, N_(2)O/O_(2) 사용여부와 부작용 발생간에서는 통계학적으로 유의한 차이는 확인되지 않았다. The combination of chloral hydrate and hydroxyzine is one of the safest and most commonly used drug regimens for sedating young, uncooperative pediatric dental patients. Midazolam IM or IN and N_(2)O/O_(2) inhalation is sometimes administered with chloral hydrate and hydroxyzinecombination when deeper and longer sedation is needed. The purpose of this study was to assess the outcome and safety of chloral hydrate, hydroxyzine and N_(2)O/O_(2) in the sedation of a large number of uncooperative pediatric dental patients and to identify variables associated with their effectiveness. In a nine-month retrospective study, 171 records of sedation performed in 94 healthy children(male 46, female 48) with mean age of 30±8 months were reviewed. The authors analyzed several variables such as age, sex, weight, methods of drug delivery, waiting time after drug delivery, treatment rendered, treatment time, adverse events, sedation outcome. Eighty five percent of sedation had success behavioral outcome. Sedation sessions rated success used more N_(2)O/O_(2) administration and had longer treatment duration than sedation sessions rated failure. A children patient under 36 months of age had enough sleep by on1y oral administration and the mean waiting time of this case was significantly shorter than that of a children patient over 36 months of age. There was a clear correlation between age and N_(2)O/O_(2) using time, but no correlation between weight and N_(2)O/O_(2) using time. There was no statistically significant difference among variables of treatment duration, N_(2)O/O_(2) administration and adverse event.

조희정,최한곤,김정애,오유경 한국약제학회 2005 Journal of Pharmaceutical Investigation Vol.35 No.2

A promising application of Lactococcus lactis is its use as live vehicles for production and delivery of heterologous proteins of vaccines and therapeutic substances. Because L. lactis has GRAS ("generally regarded as safe") status, use tested whether L. lactis could function as the carrier of the L1 protein of human papillomavirus (HPV) type 16. The RNA level expression of L1 gene was detected in L. Laois. The L1 protein was expressed in L. luctis with LI gene. The growth of strains L. lactis with an empty plasmid (pAMJ328) and L. lactis with L1-encoding plasmid (pAMJ328-L1) was slightly decreased in comparison with the growth of strains L. lactis (wild type). However, all the three strains of L lactis maintained the ability to ferment sugars primarily into lactic acid, indicating that L1 protein did not affect the biochemical property of L.. lactis. These results suggest that L. lactis. capable of carrying LI protein, might he further developed as a biocompatible oral protein delivery system.

Background : Invasive aspergillosis (IA) is an important cause of morbidity and mortality among immunocompromised patients. However, 1A is difficult to diagnose, especially in the aforementioned patient group. Recently, galactomannan assay (GMA) using enzyme immunoassay has been introduced in Korea. We evaluated its diagnostic usefulness in the diagnosis of 1A and we analyzed the results according to the underlying diseases. Materials and Methods : All patients who underwent GMA during the period from October 2007 to June 2008 were evaluated retrospectively. According to the criteria of European Organization for Research and Treatment of Cancer/Mycoses Study Group, IA was classified into four clinical categories: proven', probable', possible', and 'non' IA. Patients with 'proven' and 'probable' IA were used as the reference standards for IA. GMA was performed using Platelia Aspergillus EIA (Bio-Rad, Hercules, CA, USA). Optical density index ≥0.5 was considered positive. Results : Of the 144 patients who underwent GMA, two patients were classificed as proven' IA and sixteen patients were probable' 1A. Overall sensitivity, specificity, positive predictive value, and negative predictive value of the assay were 50% (95% confidence interval [C195), 26-74%), 88% (C195, 81-93%), 38% (CI95, 19-59%), and 93% (CI95, 86-97%), respectively. Among the 99 patients with underlying hematologic diseases, GMA showed 67% (C195, 35-90%) sensitivity and 89% (C195, 80-94%) specificity, whereas in 45 patients with underlying diseases other than hematologic diseases, sensitivity and specificity of the assay were 17% (CI95, 0-64%) and 87% (CI95, 73-96%), respectively. Conclusions : GMA showed high specificity, irrespective of the patient population. However, sensitivity of GMA was low and the assay was less sensitive in patients with underlying diseases other than hematologic diseases than in patients with hematologic diseases.

저자들은 호흡곤란, 흉부불쾌감, 심계항진 등을 주소로 내원한 환자에서 경흉부 및 경식도 심초음파 검사상 주폐동맥에서 이완기에 전행하는 지속적인 혈류의 흐름을 관찰하고, 관상동맥 조영술을 통해 좌전하행지 중간부위와 우관상동맥 근위부에서 각각 기시하여 공통경로를 이루면서 주폐동맥으로 유입되는 양측성 관상동정맥루를 보이는 드문 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. A coronary arteriovenous fistula is infrequently encountered vascular communication between a coronary artery and a cardiac chamber, a great artery or the vena cava. It is the most common congenital anomaly that can affect coronary perfusion. Bilateral involvement of coronary fistula constitutes an uncommon subgroup of coronary arteriovenous fistulas. A 69 year-old female patient presented with chest discomfort, palpitation, and dyspnea. In the echocardiography, doppler color flow imaging visualized abnormal flow signals with mosaic appearance in the main pulmonary artery during diastolic phase. Coronary angiography revealed arteriovenous fistula arising from the left anterior descending artery and the right coronary artery. Both coronary arteriovenous fistulas drained into the main pulmonary artery. We report a case of bilateral coronary arteriovenous fistula that was confirmed by echocariography and coronary angiography.
