본 연구의 목적은 첫째, 55세이상성인을 대상으로 구강보건영향지수 중 물리적동통의 유병률을 파악하고, 둘째, 55세이상성인의 구강건강충격지수 중 물리적동통의 연관요인을 파악함에 있다. 조사대상자는 2000년 국민구강건강조사시 층화무작위추출법으로 표본추출된 4,250명의 55세이상성인집단 중에서 본 연구의 목적에 동의한 1,098명의 55세이상성인이었고, 조사방법은 전화면접조사법이었다. 면접문항은 구강건강충격지수 중 물리적동통에 관련된 9개의 문항와 성, 연령, 거주지역 및 의치장착여부등에 관한 4문항을 합하여 총 13문항이었고, 동통정도의 웅답은 5점리커트척도(0-4)룰 이용하여 기록되었다. 동통유병를은 동통정도 0-1을 동통무경험자로, 동통정도 2-4를 동통유경험자로 하였고, 총물리적동통정도(PPS)는 9개의 개별물리적동통정도의 합으로 최저 0점에서 최고 36점에 분포하도록 하였다. 동통유병률에 관한 연관요인을 파악하기 위하여 다변량 로지스틱회귀분석을 실시하였고, 총물리적동통정도에 관한 연관요인을 파악하기 위하여, 다변량 선형회귀분석을 실시하였다. 두통, 치은동통, 과민성치아 둥에 관한 유병률은 각각 6.8%, 17.2% 및 26.0% 이었다. 여자는 남자에서 보다 두통유병률의 가능성이 2.3배(95% 신뢰구간=1.33,3.99) 높았고, 치은동통유병률의 가능성은 1.4배(95% 신뢰구간=1.01, 1.97) 높았다. 국부의치장착자는 의치비장착자보다 치은동통유병률의 가능성이 1.8배(95% 신뢰구간=1.20, 2.58) 높았으며, 의치장착은 총물리적동통정도를 1.58 증가시겼다(확률값=0.001). 총괄적으로, 두통유병률과 과민성치아유병률의 연관요인은 성이었고, 치은동통유병률의 연관요인은 성과 의치장착이었다.

<P><B>Abstract</B></P> <P>In this work, low-velocity impact-induced damages such as matrix cracking and delamination in composite laminates made of unidirectional carbon fiber/epoxy and woven carbon prepregs with different stacking sequences were investigated by using a poly(vinylidene fluoride–trifluoroethylene) (P(VDF-TrFE)) film sensor. The effect of insertion of film sensor having various areal ratios on the structural integrity of the host composite was investigated by conducting tensile and short beam shear tests. The findings revealed that the degradation rates of the Young's modulus, strength, and inter-laminar shear strength were in the acceptable range; the degradation rate was 7–8% even under unrealistically harsh conditions. Subsequently, low-velocity impact tests were performed by using a drop-weight impact machine (11.77–28.25 J). For damage characterization of the composite laminates, four P(VDF-TrFE) film sensors were inserted at different sites in each composite laminate at the impact point. By considering the relationships between impact energy, voltage output from the sensors, and the corresponding material failure modes, an estimation technique for the potential failure of the composite laminates that experienced low-velocity impacts was suggested.</P>

The purpose of this study was to investigate the effects of various cool-down exercises on muscular strength and endurance. After receiving a treadmill training for main exercise, the subjects conducted isotonic and isometric cool-down exercises four times for three weeks. Isotonic exercise with leg press of 10kg was repeated by 20 times and isometric exercise was conducted at flexion of hip joint and knee joint with leg press of 10kg by maintaining it for 6 sec and resting for 2 sec by 20 times. Muscular strength after exercise was measured with 1 RM by times and muscular endurance with maximum repetition frequency using time to keep for loading the weight of 10 RM and 65% of maximum muscular strength. As a result of comparing and analyzing measured values, exercise recovery shape of isotonic and isometric cool-down group were more effective than rest recovery shape of the control group. The isometric cool-down group was more effective than isotonic cool-down group. In conclusion, isometric exercise was more effective than isotonic exercise or simple rest on muscular strength and endurance.

<P>The detailed kinetics of the cytomegalovirus (CMV)-specific T cell response in hematopoietic stem cell transplant (HCT) recipients have not yet been fully assessed. We evaluated these kinetics of CMV-specific T cell response and factors associated with high CMV-specific T cell responses 1 year after HCT. In HCT recipients, CMV pp65 and IE1-specific ELISPOT assay were performed before HCT (D0), and at 30 (D30), 90 (D90), 180 (D180), and 360 (D360) days after HCT. Of the 51 HCT recipients with donor-positive (D<SUP>+</SUP>)/recipient-positive (R<SUP>+</SUP>) serology, 26 (51%) developed CMV infections after HCT. The patterns of post-transplantation reconstitution for CMV-specific T cell response were classified into 4 types: 1) an initial decrease at D30 followed by gradual T cell reconstitution without CMV infection (35%), 2) an initial decrease at D30 followed by gradual T cell reconstitution preceded by CMV infection (35%), 3) failure of gradual or constant T cell reconstitution (26%), and 4) no significant T cell reconstitution (4%). There was no significant difference between ELISPOT counts of D360 and those of D0. High CMV-specific T cell responses at D360 were not associated with high CMV-specific T cell response at D0, CMV infection, ganciclovir therapy, graft versus host disease (GVHD), and immunosuppressant use. In conclusion, there are 4 distinct patterns of reconstitution of the CMV-specific T cell response after HCT. In addition, reconstituted donor-origin CMV-specific T cell responses appeared to be constant until day 360 after HCT, regardless of the level of the pre-transplant CMV-specific T cell response, CMV infection, and immunosuppressant use.</P>
