In order to know the residual pattern of pesticides and predict to the degradation period until below MRL, we experimented diazinon, iprodinon and chlorfenapyr for shallot. They were the most detected pesticide in shallot by NAQS (National Agricultural product Quality management Service) survey. In this experiment, we sprayed those pesticides 15days before harvest and analyzed 0, 1, 2, 3, 5, 7, 10, 14 day sample to establish logical equation and to calculate DT_(50). During the cultivating period, the residue amount of diazinon was changed from 1.02 mg/kg (0 day) to 0.01 mg/kg (14 day), DT_(50) was 2.19 days, and iprodione was changed from 1.45 mg/kg (0 day) to 0.14 mg/kg (14 day), DT_(50) was 4.15 days, and chlorfenapyr was changed from 1.5 mg/kg (0 day) to 0.01 mg/kg (14 day), DT_(50) was 1.97 days. The DT_(50) of double amount in those pesticides, diazinon was 2.24 days, iprodione was 4.82 days, and chlorfenapyr was 2.24 days, respectively.

Likelihood Radio를 이용하여 주파수 도약 대역확산 신호를 검출할 수 있는 Average Likelihood(AL) 수신기나 Maximum Likelihood(ML) 수신기는 hop rate. hop duration. hopping timing offset 및 frequency offset을 정확히 알고 있다는 가정 하에서 개발된 방식이다. 그러나 주파수 도약 대역확산 신호 검출에서는 이러한 정보가 없기 때문에 별도의 hop rate, hopping tiring등의 파라미터를 추정하는 방식이 필요하다. 본 논문에서는 이러한 파라미터 추정에 오류가 있을 때 sliding window을 이용하여 검출 성능의 저하 없이 주파수 도약 대역확산 신호를 검출할 수 있는 알고리즘을 제안하였다.

The residual study of pesticide has been used in various areas, such as food safety, environmental protection, establishment of tolerance, and explaining the pathway and reaction mode of pesticides, and its importance was expected to increase further more. The aspect of food safety, the pesticide residue survey have been practiced at many organizations, but there were no verification of analytical results at present. In this experiment, we focused on instrumental stability, including response of each instrument and the recovery ratio of each organization's method. As samples for this experiment, we prepared cucumber and sesame, and chose 4 pesticides (bifenthrin, chlorpyrifos, diazinon, and ethoprophos), which were mostly detected from pesticide residue survey and widely used for each crop. The standard deviation of peak areas in the chromatogram of each pesticide were under 1.212 %, so it showed that most instruments were stable. The relationship of recovery ratio of each organization were over 0.996 for every pesticide and each organization. Finally, the analytical results for pesticide residue from each participated organization were not statically significant and we could put confidence in the result from each organization.

Running title: Cases of anesthesia for extremely low birth weight infant. Extremely low birth weight infants (birth weight < 1000 g) are prone to various morbidities such as respiratory distress syndrome, intraventricular hemorrhage, periventricular leukomalacia, patent ductus arteriosus, necrotizing enterocolitis and retinopathy. To accomplish successful anesthetic management, many precautions must be continuously taken during the operation. First, inspired oxygen concentration should be adjusted to avoid oxygen toxicity. Second, body temperature must be maintained adequately. Third, hemodynamic parameters should be kept stable. We report 2 cases of successful anesthetic management for extremely low birth weight infant who underwent ligation of patent ductus arteriosus at the neonatal intensive care unit.

The purpose of this study was to compare and analyze the relation between body composition, cardiorespiratory functions and percent heart rate recovery in obese and normal middle school female students. We used total of 12 middle school female students(3rd grade) as subject and devided them into two groups : The measurement items of cardiorespiratory functions were HR, VE, RQ, VO₂, VCO₂, VO₂/kg, O₂pulse, VE/VO₂, VE/VCO₂, before and after treadmill exercise load. The statistical analysis were M±SD and t-test for groups(α=.05) using ?? statistical package. The conclusion of this study was as follows ; 1. In 5 items(FM, LBM, %Fat, TBW, BMI) all of body composition, obese group has been significantly higher than normal group(P<0.01). 2. In heart rate and VO₂ of resting(before exercise loads) cardiorespiratory functions, normal group has been significantly higher than obese group(P<0.05). 3. In VEmax of cardiorespiratory functions after exercise loads, obese group has been significantly higher than normal group(P<0.05), and in VO₂max, obese group has been significantly higher than normal group(P<0.01). 4. In 1, 3, 5 minute percent recovery all of percent heart rate recovery after exercise loads, normal group has been higher than obese group but there was no statistical significant difference.

The purpose of this study was to examined the effect of supervised regulary aerobic exercise program with cardiorespiratory function of obese children. The subjects were 16 obese Childrens(elementary school 4∼5 grade), and engaged in regulary aerobic exercise program for 9 weeks(5 days/week, 100 min/day, 60∼70% HRmax) with mountain climbing, basketball and football. The items of cardiorespiratory function measured VEmax, HRmax, RQmax, VCO₂max, VCO₂max, VCO₂max/kg and BFmax after treadmill exercise load. The conclusion of this study was as follows ; 1. In body composition, there were significant decrease(P<0.001) after aerobic exercise for 9 weeks in body weight, percent body mass index 2. In cardiorespiratory function, there were significant increase(P<0.001) after aerobic exercise for 9 weeks in VEmax and VCO₂max by treadmill exercise load. 3. In cardiorespiratory function, there were significant increase(P<0.001) after aerobic exercise for 9 weeks in VO₂mex and RQmax by treadmill exercise load. 4. In cardiorespiratory function, there were significant increase(P<0.001, P< 0.01) after aerobic exercise for 9 weeks in VO₂max/kg and BFmax by treadmill exercise load.
