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.

<P><B>Purpose</B></P><P>Aging-induced loss of muscle mass and subsequent reduction of strength is a fundamental cause of frailty, functional decline, and disability. And this may lead to muscular dysfunction, voiding dysfunction, or urinary incontinence due to pelvic muscle weakness induced by aging. Physical exercise has been recommended for the prevention and the treatment of these age-related frail states. We investigated the effects of treadmill exercise on muscle strength, myostatin mRNA and protein expression, and gastrocnemius myocytes proliferation in aged rats to investigate the possible antiaging effects of aerobic exercise on skeletal muscles such as pelvic floor muscles and urethral rhabdosphincter muscle.</P><P><B>Methods</B></P><P>In this study, 5-month-old male Sprague-Dawley rats were used as the young-age group (n=20) and 24-month-old rats were used as the old-age group (n=20). Each group was randomly divided into two groups (n=10 in each group): the sedentary and the treadmill exercise group. The rats in the exercise groups were forced to run on a motorized treadmill for 30 minutes, once a day, for 6 weeks. For this study, a weight load test, hematoxylin and eosin staining, real-time and reverse transcription polymerase chain reaction for myostatin mRNA, myostatin western blot, and 5-bromo-2'-deoxyuridine immunohistochemistry were performed in the gastrocnemius muscle.</P><P><B>Results</B></P><P>The age-induced reduction of muscle mass and strength was associated with a decrease in myocyte proliferation and an increase in myostatin mRNA and protein expression in the gastrocnemius. However, treadmill exercise improved muscle mass and strength through suppression of myostatin mRNA and protein expression, and myocyte proliferation increase in the gastrocnemius against the aging process.</P><P><B>Conclusions</B></P><P>Aerobic exercise is a useful strategy for enhancing muscle function against aging-induced loss of skeletal muscle mass and functions.</P>

Objectives: To compare the efficacy of the Dornier Compact Delta lithotriptor with the Northgate SD-3 lithotriptor in the treatment of upper and mid-ureteral stones. Materials and Methods: A total of 243 patients without any previous experience of ESWL were treated for upper and mid-ureteral stones. 121 patients were managed with the Northgate SD-3 lithotriptor which had ultrasonography targeting system and electro hydraulic shock wave source. The other 122 patients were treated with the Dornier Compact Delta equipped with a fluoroscopic focusing system and electromagnetic shock wave source. The locations and sizes of stones, sessions, stone-free rates, auxiliary procedures, and complications of ESWL were reviewed retrospectively. In each group stone-free results were determined by KUB 1 month after the last ESWL and then efficacy quotients (EQ) were obtained. Results: Baseline characteristics were equivalent, including patient ages, sex ratio, stone numbers and locations. Using the Northgate SD-3 lithotriptor, the average sessions and stone-free rates were 1.53 and 86.8%, respectively. Using the Dornier Compact Delta lithotriptor, average sessions and stone-free rate were 1.38 and 92.6 %, respectively. Effectiveness quotient(EQ) in the Northgate SD-3 and the Dornier Compact Delta was 61 and 65, the rates of the auxiliary procedure were 9.1% and 18%. Conclusions: The Dornier Compact Delta lithotripsy resulted in a higher stone-free rate and EQ, although it was associated with a higher rate of pre-ESWL auxiliary procedures than the Northgate SD-3 Lithotripsy.

This research aims at analysis of attack technique in sepaktakraw games. For this purpose, 3 high school coaches observed and recorded each game Five times in videos of high school male players' thirty games in 2003. The conclusion from the analysis of the recorded data are as follows. 1. Scissors spike was the most popular (favorite) attack technique. Rolling spike, tapping spike and heading spike was popular in order. 2. Heading spike showed the highest success rate (73.5%) in attack technique. And tapping spike (69.5%), scissors spike (57.8%) and rolling spike (67.11) showed a lower success rate in order. In failure rate, heading spike (5.5%), tapping spike (36.5%), scissors spike (32.2%) and rolling spike (32.9%) had a higher percentage in order. 3. When receive was stable, the success rate in attach technique was 47.1%, the failure rate was 20.1%. On the other hand, when receive was unstable, the success rate in attach technique was 16.5%, the failure rate was 14.3%.

The purpose of this in vitro study was to evaluate the marginal microleakage of Class Ⅱ composite resin inlay restoration and to compare the marginal leakage of inlay with indirectly placed composite restoration and that of direct filling composite restoration. MO or DO cavity preparations were cut in 60 extracted human permanent molars. The experimental group was restored with Herculite XR inlay, Clearfil inlay, and E.O.S. inlay with dual cement. The control group was directly filled with Herculite XR after being etched and applied with dentin bonding agent. The specimens were thermocycled 1,000 times between 5℃ and 55℃. Microleakage was evaluated by use of the Methylene bule staining technique. The depth of microleakage was measured with stereomicroscope after the teeth were sectioned. The obtained results were as follows : 1. The marginal leakage was reduced in the order of Clearfil inlay, Herculity XR-inlay, E.O.S. inlay, and Herculite XR-direct filling group at the occlusal margin. 2. The marginal leakage was reduced in the order of Clearfil inlay, Herculity XR-inlay, Herculite XR-direct filling group and E.O.S. inlay at the gingival margin. 3. Generally, the marginal leakage was more greatly showed at the gingival margin than at the occlusal margin. 4. The marginal leakage was greatest at the gingival margin of E.O.S. inlay, and was the least at the occlusal margin of Clearfil inlay.
