The purpose of this study was to evaluate the mechanical thermal resistances and comfort properties of ski wear made with vapor-permeable water repellent (VPWR) fabrics and thermal insulation battings. Four types of experimental clothing were made with the combination of two VPWR fabrics (Hipora-TM® Hipora-CR® and two thermal insulation battings (Viwarm® Airseal®. Thermal resistances of ski wear were objectly evaluated by thermal manikin experiment (21±2℃, 50±5% R.H., 0.25 m/sec air velocity) and thermographic accessment (2±2℃, 0% R.H., 0.25 m/sec air velocity, and emissivity level = 1). Garment wear tests of ski wear included the measurement of the microclimate (inner temp. and relative humidity) of the experimental clothing by digital thermohygrometer and subject wear sensation using McNall's thermal comfort ratings. Clo values of experimental clothing 4 (Hipora-CR® Airseal® and 1(Hipora-TM® Viwarm® were significantly higher than those of 2 (Hipora-TM® Airseal® and 3 (Hipora-CR® Viwarm®. Thermal resistances in the points of breast, back, belly, and loin was significantly higher than those of upper arm, fore arm, and shank of measuring points on the thermal manikin. According to the color map of the thermogram, the experimental clothing 4 indicated higher surface temperatures than the others showing more yellowish spots on the surface of clothing. Inner temperature of experimental clothing was not significantly different among the four types of ski wear, but relative humidities of experimental clothing were significantly different. Relative humidities of experimental clothing 1 and 3 showed higher than those of 2 and 4. Relative humidity of experimantal clothing was affected largely by the thermal resistance of thermal insulation batting materials. The sujbject wear sensation of experimental clothing 2 and 4 showed lower humidity than the others. Subject wear sensation was affected more by humidity sensation than by thermal sensation.

The purpose of this study is to investigate the suitability of cotton and nylon socks according to the physical constitution of five elements To evaluate the suitability of materials of socks, we measured force of fingers by Digital O-Ring Tester The overall comfort sensation was measured by the ASHRAE scale in order to find out if there is any relationship between the results of 0-Ring Test and the subjective comfort ratings The results were as follows' 1 There were distinct differences in force of fingers of cotton and nylon socks according to the physical constitution of five elements Subjects who were judged as the Mok(Jupiter) type showed larger force of fingers in cotton socks than in blended socks, and subjects who were judged as the Kum(Venus) type showed the smallest force of fingers in nylon socks 2 Most subjects evaluated nylon socks as the most uncomfortable, but the comfort sensation of socks was different according to the physical constitution. 3 No clear moving tendency between force of fingers and the comfort sensation was found. Therefore, we suggest that minute change of human body such as force of fingers be measured as well as comfort sensation to investigate the suitability of clothing materials for the individual

Unravelling the link between technological M&A and innovation performance using the concept of relative absorptive capacity

조길수,박군호,강진아 기술경영경제학회 2016 ASIAN JOURNAL OF TECHNOLOGY INNOVATION Vol.24 No.1

Technological merger and acquisition (M&A) has become an increasingly popular mode ofinnovation for firms. We investigate the determinants of innovation creation throughtechnological M&As. Based on the concept of relative absorptive capacity, the studyexamines how the acquiring firm absorbs and assimilates the knowledge of the acquiredfirm and creates innovation. Specifically, the technological M&As are examined bypresenting dyadic perspective variables, including technological similarity and technologicaldigestibility which affect the assimilation, transformation, and exploitation processes of theabsorptive capacity. We additionally investigate the role of M&A experience as a moderatorof dyadic characteristics and innovation performance of technological M&As. Two hundredand twelve cases of technological M&As in the biopharmaceutical industry from 1993 to2007 are investigated using zero-inflated negative binomial regression and negativebinomial regression. The findings confirm a positive effect of acquiring small firms having amodest level of similar knowledge on post-M&A innovation performance. Moreover, thisstudy highlights the importance of the dyadic perspective in advancing the understanding oftechnological M&A.

This study was carried out to investigate the silhouette and total hand value(THV) of cotton/PET mixture fabric, and to study the dyeing on these properties. Specimen was union-dyed with reactive dyes for the portion of cotton and disperse dyes for the portion of polyester under two bath system. Mechanical properties of specimens were measured by KES-FB system. The silhouette types were derived from the standardized canonical discriminant function proposed by Niwa. THV of the specimens which belong to Drape and Hari type was calculated by Niwa's new equations, KN-305-DLDY and KN-305-HLDY respectively. The results were as follows: 1. In terms of mechanical properties EM and tensile energy in tensile properties and bending properties of PET yarns were higher than those of cotton yarn before and after dyeing. After dyeing. cotton/PET fabrics showed lower values of tensile, bending, and surface properties. As the result the specimen became to be more elastic, more flexible, and smoother. 2. Silhouette type of cotton/PET fabric was Hari before and after dyeing. But the standardized values of bending rigidity and shear stiffness were inclined to move to the ranges of those of Drape type fabrics after dyeing. 3. THV of cotton/PET after dyeing increased a little but was about the same to that before dyeing

본 연구의 목적은 오행체질별로 면과 나일론 양말 소재의 적합성에 차이가 있는지를 살펴보는 것이다 이를 위해 본 연구에서는 채질별로 디지털 오링 테스터를 이용하여 악력을 측정하고, ASHRAE의 정신 심리학적 척도를 이용하여 쾌적감을 평가하였다. 또한 Spearman 의 순위상관분석을 통해 객관적인 악력 측정값과 주관적인 쾌적감 평가치간에 상관관계가 있는지를 살펴보았다. 본 연구의 결과는 다음과 감다 1 체질별로 면과 나일론 양밀 소재에 따라 악력에 차이가 있으며, 특히 금형의 경우에 나일론 소재 착용시에 익력이 작아지는 경향이 뚜렷하게 나타났다. 따라서 자신의 채질에 적합한 의복소재를 선택하여, 작용하는 것이 좋을 것으로 판단된다. 2 쾌적감 평가 결과, 대부분의 피험자들이 면이나 혼방 양말에 비해 나일론 양말을 불쾌 하다고 평가하였으며, 지각하는 불쾌감의 정도는 체질에 따라 다른 것으로 나타났다. 3 객관적인 악력 측정치와 주관적인 쾌적감간에는 유의한 상관관계가 나다나지 않았다. 생체 에너지 변화를 나타나는 악력 변화와 일반적 쾌적감의 개념은 다르다고 판단되며, 인세 기의 변화기 아주 크지 않을 경우에는 인간이 감지할 수 없다고 판단된다. 따라서, 착용자에게 적합한 의복에 관한 후속연구에서는 쾌적감에 관련된 요인의 평가 뿐 아니라, 체내의 마 세 에너지 변화에 대한 평가도 이루어져야 한다고 판단된다.

In order to quantify sound color of rustling sounds of fabrics and investigate the characteristics of specimens classified by sound color factors through cluster analysis, rustling sounds of selected 65 commercial fabrics were produced by the sound generator developed for this study. ΔL, Δf, and LPT values were calculated form sound spectra forms presented by FFT analysis. Specimens were classified into four clusters with ΔL, Δf, and LPT by use of cluster analysis. Means for ΔL and Δf showed significant differences among clusters. Specimens of cluster 1 had higher ΔL and Δf than those of specimens of other cluster. Specimens of cluster 3 lower ΔL and Δf. These indicated that specimen of cluster 1 has deep and less steep curve in sound spectra and those of cluster 3 had shallow and steep curves. It was supposed that specimens of cluster 1 and 3 would generate sounds of unlike color due to the differences of ΔL and Δf.
