      • 테니스 포핸드 스트로크 시 왼팔의 이용 유무가 스트로크의 정확성에 미치는 영향

        우상연,최성범,김호묵 순천향대학교 기초과학연구소 2011 순천향자연과학연구 논문집 Vol.17 No.1

        The purpose of this study is to analyze and compare accuracy and kinematic characteristics of forehand strokes upon using the left-hand and non the using left hand in tennis. Six unskilled collegiate players who complied primary tennis course participated in this study. Subjects were requested to hit 10 balls with 4 types each: first, it was two directions(down the line, cross), second, it was two velocities(slow ball, fast ball) and then it was type of using left hand. Variables such as accuracy, time, distance, angle and velocity variables were measured by USPTA method and video cameras. The results of this study are as follows: 1) accuracy of hitting balls was not different according to the type of using left hand. While there was an interaction between ball velocity and hitting direction. 2) impact positions of hitting ball were not different according to the type of using left hand. While impact positions were done near by target direction in cross direction then down the line direction. 3) shoulder rotation angle was not different according to the type of using left hand. While shoulder rotation angle was grater in down the line direction than cross direction. 4) the maximum velocity of racket head was faster in using left hand than non using left hand.

        Evaluation of Hot Deformation and Dynamic Recrystallization Behaviors of Advanced Reduced-Activated Alloy (ARAA)

        Sang‑Wook Kim,Hyeon‑Woo Son,Taek‑Kyun Jung,Young‑Bum Chun,Yi‑Hyun Park,Ji‑Woon Lee,Soong‑Keun Hyun 대한금속·재료학회 2019 METALS AND MATERIALS International Vol.25 No.4

        The hot deformation behavior of advanced reduced-activation alloy (ARAA) was investigated using hot torsion tests. Thefl ow stress decreased as deformation temperature increased and as strain rate decreased. The fl ow behavior demonstratedthe typical dynamic recrystallization (DRX). Based on the constitutive analysis of peak stress, the activation energy for hotdeformation was found to be 330.3 kJ mol −1 . Peak stress was analyzed as a function of the Zener–Hollomon parameter, andcalculated and experimental values were in good agreement. A DRX kinetic model for ARAA was derived with deformationconditions based on the Avrami-type model. It was confi rmed that the volume fraction of dynamically recrystallized grainsincreased as deformation temperature increased and as strain rate decreased. The necklace structure and grain boundarybulging were observed in the deformed microstructure of ARAA. The suggested DRX mechanism for ARAA during hotworking is discontinuous DRX.

        To a suspension of 1-cyclopropyl-6,8-difluoro-1,4-dihydro-7-{3,7-diazabicyclo[3.3.0]oct-1(5)-en-3-yl}-4-oxo-3-quinoline carboxylic acid(C1) in sodium hydroxide solution and water is added dropwise with stirring carbon disulfide. [6R][6α, 7β(Z)]]-7-[[[(2-Amino-4-thiazoly)methoxyimino]-acetyl]amino]-3-[[[[7-(3-carboxy-1-cyclopropyl-6,8-difluoro-1,4-dihydro-4-oxo-7-guinolonyl)-3,7-diazabicyclo[3.3.0 ]act-1(5)-en-3-yl]thioxomethyl]thio]methyl]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-en-2-carboxylic acid (DACD) was synthesized from 1-cyclopropyl-6,8-difluoro-1,4-dihydro-7-[7-(mercapto)thioxomethyl-{3,7-diazabicyclo[3.3.0]oct-1(5)-en-3-yl}]-4-oxo-3-quinoline carboxylic acid disodium salt(C2) and cefotaxime. The in vitro activity of novel dual-action cephalosporin, DACD, was compared with the in vitro activities of CENO(cefotaxime 3'-norfloxacin dithiocarbamate), cefotaxime, and norfloxacin against a variety of bacterial species. In vitro activity of DACD was superior to that of norfloxacin against Streptococcus pyogenes. Against Gram-positive and Gram-negative bacteria, its activity was almost equal to that of CENO.

        연구목적 : 한국판 Swanson의 주의력 결핍 장애 척도(이하 SNAP)의 신뢰도와 타당도를 검증하고, 이를 국내 실정에서 주의력결핍 과잉행동장애 환자를 선별할 수 있는 평가용 도구로서 적합한지 여부와 연구에 사용할 수 있는지를 알아보고자 하였다. 방 법 : 1998년 7월 1일부터 2001년 9월 30일까지 영남대학교 의료원 신경정신과 외래를 방문한 주의력결핍 과잉행동장애 환자 392명과 정상대조군 432명을 대상으로 SNAP을 시행하였다. 결 과 : 남녀 간의 SNAP 척도 점수비교에서, 환자군에서는 유의한 차이가 없었으나 정상 대조군에서는 남자가 유의하게 높게 나타났다(p<.01 ∼ .001). 검사-재검사 신뢰도 검증에서 신뢰도 계수는 각 하위 척도에서 .85에서 .92로 모두 만족할 만큼 높았다(p<.05). 내적일관성에 의한 신뢰도 검증에서 정상 및 환자군에서 각 하위척도별로 Cronbach α값이 .80(p.05)이상으로 나타났고, 반분신뢰도는 정상 및 환자군에서 각 하위척도별로 0.731에서 .866사이였다(p<.05). 주의결핍장애 평가 척도-가정관(Attention Deficit Disorder Evaluation Scale-Home Version) 및 소아기 집중력 문제 척도(Childhood Attentin Problem Scale)와의 준거 타당도는 ADHD 환자군에서 .342에서 .713사이였고(p<.05), 정상 대조군에서 .551에서 .789였다(p<.05). 요인분석을 해 본 결과 본 척도는 3개의 요인으로 분류되었는데, 부주의(inattention) 요인, 충동성/과잉행동(impulsivity/hyperactivity)요인, 또래 관계(peer interaction)요인으로 구분되었다. 본 척도가 정상인과 환자를 감별할 수 있는 척도인가를 알아보기 위한 감별 타당도 검사를 해본 결과 87.5%를 분류하여 높게 나타났다. 환자와 정상인을 구분하는 점수인 절단점은 표준편차 1.5를 절단점으로 잡을 때 이는 백분율로 93percentile에 해당하는 점수로서 각 소척도 점수에서 남자(0.98∼1.65)와 여자(0.64∼1.38)의 절단점이 다르게 나타났으며 남자가 높게 나타났다. 결 론 : 이상의 결과에서 볼 때 한국판 SNAP 평가 척도의 신뢰도와 타당도가 입증되었고 환자를 판별하는 능력이 우수하여 향후 ADHD 연구에 유용한 도구로 사료된다. Objectives : The purpose of this study was to examine reliability and validity of Swanson's attention deficit disorder sacale(SNAP). Method : SNAP was administered to 432 elementary school students and 392 patients who were diagnosed as attention deficit hyperactivity disorder in Yeungnam university hospital from 1998 July to 2001 September. Results : In the reliability test, the test-retest reliability coefficient was significantly high and that of inattention was 0.85, that of impulsivity was 0.90, that of hyperactivity was 0.90 and that of peer interaction was 0.92(p<.05). In the reliability test by internal consistency, the Cronbach α coefficient was above 0.80 at each subscale in both patients and normal control group(p<.05). The split-half reliability coefficient by first-second half method showed high correlation and those of each scales were from 0.731 to 0.866 in both patients and normal control group(p<.05). The criterion validity of SNAP with Attention Deficit Disorder Evaluation Scale-Home Version(ADDES-HA) and Childhood Attention Problem Scale(CAP) scale was from 0.342 to 0.713 in patients group, from 0.551 to 0.789 in normal control group(p<0.05). The discriminant ability between ADHD and normal subjects by SNAP was 87.5%. Conclusion : In this point of view, SNAP scale showed high reliability and validity in applying to Korean subjects and was proved to be useful screening tool for attention deficit hyperactivity disorder reserch.

      • Alginate Bead를 이용한 고분자 약물의 제어방출형 약물수송체

        황성주,이계주,조항범,이기명,김종국 충남대학교 약학대학 의약품개발연구소 1993 藥學論文集 Vol.9 No.-

        The purpose of this paper is to explore the possible applicability of alginate beads as an oral controlled release system of polymeric drugs. Cellulases was used as a model polymeric drug. The release of cellulase from alginate beads was moderately affected by the ratio of cellulase to sodium alginate and strongly affected by CaCl_2 concentration. However, the release was not particularly affected by the other factors such as sodium alginate concentration and curing time. The drug was not released from alginate beads at pH 1.2 but was released continuously up to 8 hr at pH 6.8. At pH 6.8, the beads were swollen highly up to 3 hr, thereafter, were eroded into the bulk solution up to 6 hr, completely. Drug release from the beads can be caused due to diffusion and erosion of the matrix. Activity of cellulase was reduced when alginate beads containing cellulase were stored in simulated gastric juice. Further investigation would be necessary to improve the acid resistance of beads. Since the release of cellulase as a model polymeric drug could be controlled by tthe regulation of the preparation conditions of alginate beads, the alginate beads may be used for a potential oral controlled release system of such polymeric drugs as polypeptide drugs.
