PDMS-PU 탄성체의 합성과 물성 및 Zwitterionization에 관한 연구

윤정욱,왕은진,백남철 慶熙大學校 材料科學技術硏究所 1992 材料科學技術硏究論集 Vol.5 No.-

The mechanical properties of polyurethane elastomer synthesized from hydroxybutyl-terminated polydimethylsiloxane(PDMS) of molecular weight 1000 and 4,4'-methylene diphenyldiisocyanate(MDI) were investigated. Hard segment content varied from 33% to 56% and various chain extender with 1,4-butanediol(BD), N-methyldiethanolamine(MDEA) or ethylene diamine(ED) were used in the segmented polyurethane block copolymer. The MDEA-extended materials were zwitterionized by using 1,3-propane sultone. By using gel permeation chromatography, infrared spectroscopy, differential scanning calorimetry and universal tensile Testing machine, physical and thermal properties of these polymers were investigated. All of these polyurethane elastomer showed phase separation. BD-extended material shows a higher tensile strength for the higher hard segment content material. MDEA-extended materials which were ionized by 1,3-PS exhibited better tensile properties than un-ionized copolymer. The zwitterionomer material exhibited ionic aggregation within the hard domain. Hard domain cohesion was found to be a important factor in determining the tensile properties of the elastomers.

Purpose: Although ERV (Energy Recovery Ventilator) is operating during open hours all the time, students tend to be least satisfied with the indoor air quality of library. This discomfort is getting apparently observed while more students have seated longer time. This study aims to measure whether the supplied airflow rate per capita is sufficient against the law-enforced CO2 concentration - 1,500 ppm in an actual university library. Also this study aims to perform a pilot test of the DCV (Demand Controlled Ventilation) based on number of occupants, as a compensation for the increased airflow rate that could be a recommended reaction after through measuring currently supplied airflow rates. Method: We first have fixed the supplied airflow rates while letting go off entering and leaving students as many as the number of students who usually visit the library, and then measured the marginal number of students at each flowrate, which makes CO2 concentration under 1,500 ppm. Also we have fixed the 35 students and then measured the desired airflow rate that maintain CO2 concentration under 1,500 ppm. Lastly, we have tested the occupant-based DCV for the ERV following combinations of the marginal number of students and the desired airflow rates. Result: It is observed that 1) more occupants require larger airflow rates, as expected. It should be noted that when occupants more than a certain number stay in the library, CO2 concentration is increasing faster than it would do when there is smaller number of occupants; 2) when library is pretty much occupied, the law-enforced ventilation rate per capita may not be sufficient to meet CO2 concentration under 1,500 ppm; 3) the occupant-based DCV well contains CO2 concentration under 1,500 ppm upon varied number of occupants, while saving surplus airflow volumes and thus saving the electricity.

This study aims to identify specifically whether emotional sensitivity of Taekwondo performance audience affects emotional factors and preference for Taekwondo performance content and further provide basic data to develop and revitalize Taekwondo performance as a representative cultural content of Korea. The author obtained the following results. First, emotional sensitivity was found to have substantial impacts on pleasure-oriented attitude as a subfactor of emotional factors and awareness of presence. Second, pleasure-oriented attitude had a profound influence on awareness of presence. Third, pleasure-oriented attitude and awareness of presence as sub-factors of emotional factors commonly influenced over both theatrical Taekwondo performance and musical-style Taekwondo genre. 본 연구는 태권도공연 관람객의 감정 민감도가 감성적 요인 및 태권도공연 장르별 관람선호도에 영향을 미치는지를 구체적으로 규명하여 한국대표 문화콘텐츠의 태권도공연 개발 및 활성화를 위한 기초자료를 제공하는데 그 목적이 있다. 연구의 대상은 2017년 태권도공연 ‘모던태권도 킥스’룰 관람한 관람객을 모집단으로 선정하였으며, 편의표본추출법을 이용하여 182명 표본을 추출하였다. 수집된 자료는 SPSS 22.0을 활용하여 빈도분석, 탐색적 요인분석, 신뢰도분석, 상관관계분석 및 다중회귀분석을 통해 다음의 결론을 도출하였다. 첫째, 감정 민감도는 감성적 요인의 하위요인 쾌락적 태도와 현장성 인식 요인에 유의한 영향을 미치는 것으로 나타났다. 둘째, 쾌락적 태도는 현장성 인식에 유의한 영향을 미치는 것으로 나타났다. 셋째, 감성적 요인의 하위요인 쾌락적 태도와 현장성 인식은 태권도공연콘텐츠 장르별 관람선호도의 연극적 태권도공연과 뮤지컬적 태권도공연 장르에 모두에 유의한 영향을 미치는 것으로 나타났다.

This study aims to clarify the perdicitive model of the relationship between performance continuous intentionand performance continuous behaviors from the viewpoint of the Theory of Planned Behavior (TPB). Forthis purpose, 180 copies of questionnaire sheets were collected from the performers who participated in aplay of taekwondo performance arts. Excluding 38 copies of questionnaire sheets completed inadequately, 142of them were used for final analyses. The collected data were naalyzed using SPSS 12.0 and AMOS 7.0 sof-tware programs. Specifically, frequency analysis, exploratory factor analysis, confirmatory factor analysis, correlationanalysis, and structural equation modeling were conducted. From the results of these analyses, the followingconclusions were drawn. First, the attitudes of the taewkondo performer had positive influences upontheir continunos intentions. Second, the subjective norms of the taekwondo performer had positive influencesupon their continuous intentions. Third, the perceived behavioarl control of the performer had positive infl-uences upon their continuous intentions. Fourth, the perceived behavioral control of the taekwondo performerhad positive effects on their continuous behaviors. Finally, the continuous intentions of the taekwondo performerhad positive impacts on their continuous behaviors.

PURPOSE: This study sought to evaluate muscle activity and foot pressure during gait, and balance in female college students with genu valgum. METHOD: Participants were assigned based on their Q-angle to genu valgum group greater than 20° (GVG, n = 12), unilateral genu valgum group greater than 20° (UVG, n = 11), and control group (CON, n = 13). All subjects were evaluated for balance (Trace length, C90 area, C90 angle, and the Romberg test), muscle activity (gluteus medius; GM, tensor fasciae latae; TFL, vastus medialis; VM, vastus lateralis; VL, biceps femoris; BF, gastrocnemius; GCM and tibialis anterior; TA) and foot pressure (F/F ratio, R/F ratio, Hallux, 2~5 toe, 1st MT, 2~4 MT, 5th MT, Midfoot, M/heel, and L/heel) during gait. RESULTS: Romberg test showed significantly increased loss of balance in the UVG group compared with the CON. In the forward position, the imbalance was significantly increased in the UVG and GVG groups compared to the CON. Muscle activity of VL, GCM, and TA significantly increased in the GVG group compared with the CON. Static foot pressure, 1st MT significantly increased in the GVG compared to the CON group. The 5th MT significantly decreased in the CON compared with the GVG group. The R/F ratio significantly decreased in the GVG compared to the CON group. In dynamic foot pressure, the 2∼5 toe significantly increased in the GVG compared with the UVG group. The left 5th MT significantly decreased in the UVG compared with the CON and GVG groups. CONCLUSION: These results indicate that genu valgum has a negative effect on balance, muscle activity, and foot pressure during gait in female college students.
