The purpose of this study was to evaluate of subjective handle by consumers in waterproof and water vapor permeable coated fabrics. The survey was conducted by means of the sensory test during Jan. 15 to Mar. 15, 1999. Total 4032 data were collected including male, female, no major, and major people who are studying clothing and textile in college. Handle were observed by subjective method as the washing was repeated for 4 kinds of material which have different water vapor transmission, and the change of water vapor transmission each others. The data were analysed for t-test, ANOVA, factor analysis, and Duncan multiple test. Consumers evaluated that water and water vapor permeable coated fabrics were less elasticity. There were little difference in wrinkles, thickness, and luster for polar adjective words. Clearer evaluation was shown by female group or major group than others. The results of factor analyses for 18 polar adjective words on subjective handle test yielded 4 factors, that were 'elastic property', 'surface property', 'thickness and weight property' and 'thermal and rigid property'. The surface properties were deteriorated remarkably as washing was repeated and significant difference were observed. Significant differences of subjective handle in 4 factors were shown in fabric types.

이지연,김용수,김진섭,박진현,최윤희,전덕훈,김경 대구대학교 특수교육재활과학연구소 2010 再活科學硏究 Vol.28 No.1

본 연구의 목적은 뇌졸중 환자의 재활을 위하여 불안정 지지면을 이용한 운동 프로그램이 균형 능력과 운동 기능 능력에 미치는 효과를 알아보고자 실시하였다. 불안정 지지면의 이용한 치료는 임상적으로 뇌졸중으로 인한 편마비 환자뿐만 아니라 스포츠 손상 및 노인들의 질환 등 다양한 병인을 가진 환자들의 치료에 이용되고 있다. 대부분의 뇌졸중 환자들은 재활 훈련을 할 수 있는 병원이나 기관에서 치료를 받을 때에 지지면의 차이를 제공함으로써 보다 더 안정한 지지면에서 적응할 수 있는 방법이 요구되고 있다. 하지만, 아직도 불안정 지지면을 이용한 구체화된 치료적 운동 방법과 객관적 평가에 대한 연구가 미비한 실정이다. 이러한 문제점을 해결하기 위하여 최근 뇌졸중 환자의 불안정 지지면과 이론적 근거를 바탕으로 한 운동 프로그램에 대한 연구가 더욱 필요하다. 본 연구에서는 실험군과 대조군이 같은 운동 프로그램을 적용하였을 때, 두 그룹 간에서 나타나는 균형 향상과 운동 기능 향상에 어떠한 효과를 주는지 살펴보고자 하였다. The purpose of this article was to study the effect of the exercise programme that uses the unstable supporting surface to rehabilitate cerebrovascular patients on balance ability and exercise function ability. The therapy is being clinically used for the patients with diverse pathological factors such as hemiplegia caused by CVA, sports injury, and diseases in the elderly. when most patients with CVA are treated in the hospital or institute that can provide rehabilitation training, they need to be given the way to adjust more stable surpporting surface by being provide with various stages of surface. However, the actual therapeutic exercises is still needed and the study for objective assessments wants conducting. To solve these problems, the study of unstable surface exercise programmes based on the evidences recently need to be made for the patients with CVA. in this study, we intend to look into what effects on the balance improvement and the exercise function are different from the experimental group to the control group with the same programme applied to the two groups.

Poly(p-phenylenesulfide)와 poly(p-phenylene)으로부터 제조된 탄소를 리튬이온 2차전지용 음극재료로 사용하여 전기화학적특성을 연구하였다. 이들 고분자들을 질소 분위기하에서 승온속도 2℃/min로 1000℃까지 상승시킨 후, 1시간 동안 탄화시켜 탄소를 제조하였다. Poly(p-phenylene)으로부터 제조된 탄소가 보다 더 규칙적인 구조를 가지기 때문에 Poly(p-phenylenesulfide)으로부터 제조된 탄소보다 더 많은 용량과 충방전 효율을 나타내었다. 수산화리튬과 염화주석(Ⅱ)을 첨가하여 용량의 증가와 충방전 효율의 증가를 가져올 수 있었다. 이중에서 poly(p-phenylene)에 염화주석(Ⅱ)을 첨가시켜 제조된 탄소가 가장 큰 충방전 용량과 충방전 효율의 향상을 가져왔다. Carbon inaterials manufactured from poly(p-phenylene sulfide) and poly(p-phenylene), were studied on electrochemical characteristics as anode materials for lithium ion secondary battery. These polymer precursors were heat treated for 1hr at 1000℃ with the rate 2℃/min under nitrogen atmosphere. Carbon manufactured from poly(p-phenylene) showed higher capacity and coulomb efficiency of charge/discharge than carbon from poly(p-phenylene sulfide) because the former has better ordered structure. Carbon manufactured from polymer precursors adding stannous chloride or lithium hydroxide showed higher capacity and better efficiency of charge/discharge. Also, carbon manufactured by adding stannous chloride to poly(p-phenylene) showed the highest capacity and efficiency of charge/discharge.

조민우,김지연,김덕수,최경규 大韓齒科保存學會 2010 Restorative Dentistry & Endodontics Vol.35 No.5

연구목적: 본 연구는 상아질 접착제의 잔류 용매가 접착 효율에 미치는 영향을 평가하고자 하였다. 연구 재료 및 방법: 본 연구에서는 5세대 2단계 산부식형 접착제와 7세대 단일과정 자가부식형 접착제를 사용하였다. 상아질 접착제의 증발률과 전환률, 적용 후 용매의 공기건조 방법에 따른 미세인장결합강도를 측정하였으며 접착 계면을 FE-SEM을 이용하여 관찰하였다. 결과: 1. 시간에 따라 접착제의 증발률은 증가하나 접착제의 종류에 따라 증가 양상이 서로 달랐다. 2. 대부분 전환률은 증발률에 비례하는 경향을 나타내었다. 3. 공기건조 방법에 따라 결합강도는 대부분 under군, control군, over군 순으로 증가하는 양상을 나타내었다. 4. FE-SEM에서 아세톤을 용매로 사용하는 접착제는 공기건조 방법에 따라 droplet이나 gap이 관찰되었다. 결론: 상아질 접착제의 잔류 용매는 접착 효율에 부정적인 영향을 미치기 때문에, 상아질 접착제의 선택과 사용 시 용매의 종류와 특징에 대한 적절한 이해가 필요할 것이다. Objectives: The purpose of this study is to evaluate bonding efficacy by means of measuring the effect of remained solvent on Degree of conversion(DC) and μTBS and FE-SEM examination. Materials and Methods: Two 2-step total etching adhesives and two single-step self etching adhesives were used in this study. First, volume weight loss of 4 dentin adhesives were measured using weighting machine in process of time in normal conditions and calculate degree of evaporation (DE). Reaction/reference intensity ratio were measured using micro-Raman spectroscopy and calculate DC according to DE. Then 2 experimental groups were prepared according to air-drying methods (under, over) and control group was prepared to manufacturer's instruction. Total 12 groups were evaluated by means of micro tensile bond strength and FE-SEM examination. Results: Degree of evaporation (DE) was increased as time elapsed but different features were observed according to the kind of solvents. Acetone based adhesive showed higher DE than ethanol and butanol based adhesive. Degree of conversion (DC) was increased according to DE except for S³ bond. In μTBS evaluation, bond strength was increased by additional air-drying. Large gaps and droplets were observed in acetone based adhesives by FE-SEM pictures. Conclusions: Additional air-drying is recommended for single-step self etching adhesive but careful consideration is required for 2-step total etching adhesive because of oxygen inhibition layer. Evaporation method is carefully chose and applied according to the solvent type.

강정숙,최지영,차영주,김영주,김덕례,여명구,박열 조선대학교 생명과학연구소 1998 생명과학 연구 Vol.6 No.-

본 연구는 병원성 세균인 Chlamydia trachomatis(C. trachomatis)가 숙주세포에침습시 C. trachomatis의 병원성 인자와 C. trachomatis와 상호작용하는 숙주 세포막의 인자를 규명함으로써 숙주세포에 대한 감염율을 향상시켜 보다 향상된 진단 방법을 개발하기 위하여 수행하였다. C. trachomatis로 감염된 세포에서 기본소체의 막 단백질을 분리한 결과 각 혈청형의 39 kDa과 42 kDa에서 major outer membranes(MOMPs)이 관찰되었으며, 혈청형 E와 G의 MOMPs는 42.5 kDa으로 동일하였지만 혈청형 F, H, I, 그리고 K의 MOMPs는 각각 다르게 관찰되었다. C. trachomatis가 숙주세포로 침습시 관련된 병원성 인자에 대하여 조사하고자 단층세포로 배양된 배양용기에 C. trachomatis를 24, 48 그리고 73시간대별로 접종시켜 관찰한 결과 72시간의 MOMPs의 양이 가장 많이 증가하였으며 이 결과로 MOMPS이 C. trachomatis 병원성에 중요한 작용을 함을 확인할 수 있었다. C. trachomatis가 침습시 숙주세포의 막 단백질 변화양상을 관찰하기 위해 정상세포와 C. trachomatis로 1, 2, 3 그리고 4시간대별로 접종 시간을 달리한 숙주세포의 막 단백질을 분리한 결과 42 kDa의 단백질 양이 Chlamydia에 감염된 세포 내에서 증가됨을 관찰할 수 있었다. 이로 42 kDa의 막 단백질이 침습시 숙주세포 표면에 대한 수용체로서 작용함을 알 수 있었다. The present study was performed to analyze the pathogenic factors involved in the invasion process of Chlamydia trachomatis(C. trachomatis) into McCoy cells. In this study, elementary bodies(EBs) of C. trachomatis serotypes(E, F, G, H, I, K and LGV) could be isolated by the method of Percoll density gradient centrifugation and the pathogens of serotypes were also compared from whole-cell lysates by using sodium dodecyl sulfate-polyacrylamide gel elelectrophoresis. All chlamydial serotypes showed a single predominant protein ranging from 39 to 42 kDa. The major outer membrane proteins(MOMPs) of the E and G serotypes had an identical molecular weight of 42.5 kDa. In contrast, the MOMPs of the F, H, I and K serotypes were showed different molecular weights of MOMPs. By immunoblotting with anti-MOMP antibody it was revealed that the quantify of MOMPs was time-dependently increased when McCoy cells were infected with Chlamydia for 24, 48 and 72 hr. These results indicated that MOMPs are closely related to chlamydial infection into the host cell.
