This study examines the effect of the structural properties of F/W wool knit fabrics for woman's knitwear on the perceptions of textures and sensible images of consumers and present basic data for textile designing by analyzing the relationship among the structural properties, mechanical properties, objective hand measurements and preferences. A total of 12 kinds of knit fabrics were prepared and investigated in terms of the differences in the subjective, mechanical properties and objective hand measurements according to the structural properties of knit fabrics. The data were analyzed by t-test. The subjective hand attributes of wool knits through factor analysis are categorized into 6 factors. In particular, the 'active/comfort' factor is a meaningful result that reflects the unique characteristics of knit fabrics compared to woven fabrics. Mechanical properties and objective hand measurements have a greater effect on textures than on sensible images; in addition, the structural properties, 'gauge' was the most important factor to influence the subjective evaluation.

최근 호주의 CSIRO에서 개발된 고광택 wool 섬유인 "옵팀"$^{(R)}$ 이 수입되어 고감성의류 제조에 산업화 되고 있다. 그러나 "옵팀"$^{(R)}$ 섬유의 가격이 너무 비싸 소재수급이 원활치 못한 실정이다. 본 연구에서는 호주에서 개발되어 상용화되고 있는 기술인 $Optim^{(R)}$ wool 연신기술과는 다른 물빨래가 가능하며 광택이 있으며 낮은 생산 코스트를 가지는 소모연신사를 개발하는 것을 목적으로 한다. 이를 위해서 연신사가 개발된 연신기계를 이용하여 만들어지며 이를 사용하여 고감성직물을 제직하였다. 이들 직물시료의 여러 가지 물성을 측정하고 의류의 봉제성과 의복형성성능과 같은 의류의 특성이 분석되었다. 이 연구를 통하여 마지막 목적인 옵팀섬유와 같은 고광택을 가진 소모 연신사를 사용하여 고감성직물을 만드는 것이 이루어졌다.

In this study, the high-resolution numerical simulations considering detailed anthropogenic heat, albedo, emission and roughness length are analyzed by using single layer Urban Canopy Model (UCM) in Weather Research Forecast (WRF). For this, improved urban parameter data for Seoul Metropolitan Area (SMA) was collected from global data. And then the parameters were applied to WRF-UCM model after it was processed into 2-dimensional topographical data. The 6 experiments were simulated by using the model with each parameter and verified against observation from Automated Weather Station (AWS) and flux tower for the temperature and sensible heat flux. The data for sensible heat flux of flux towers on Jungnang and Bucheon, the temperature of AWS on Jungnang, Gangnam, Bucheon and Neonggok were used as verification data. In the case of summer, the improvement of simulation by using detailed anthropogenic heat was higher than the other experiments in sensible flux simulation. The results of winter case show improved in all simulations using each advanced parameters in temperature and sensible heat flux simulation. Improvement of urban parameters in this study are possible to reflect the heat characteristics of urban area. Especially, detailed application of anthropogenic heat contributed to the enhancement of predicted value for sensible heat flux and temperature.

본 연구는 하회탈이 갖고 있는 감성적 요인에 대해 알아보고 문화상품과 관련한 제품디자인 개발에 도움이 되고자 시도되었다. 하회탈 이미지 평가를 위해 감성 형용사 어휘 32개를 추출하여 분석한 결과 첫째, 32개의 감성 평가 어휘로 하회탈 이미지에 대해 알아본 결과, '매력성', '향토성', '흥미성', '역동성', '정교성'의 5개 요인이 나타났다. 둘째, 하회탈 종류에 따라 향토성과 흥미성에서 감성 차이가 있었다. 특히 양반탈이 초랭이탈보다 향토성이 강하며, 중탈, 백정탈 및 부네탈보다는 흥미성이 더욱 높은 것으로 나타났다. 셋째, 하회탈 상품의 재질에 따라 정교성에서 감성 차이가 있었고, 특히 유리 재질에 대해 정교한 이미지를 가지고 있었다. 넷째, 하회탈의 감성이미지는 인구통계학적 특성(나이, 성별, 학력)과 제품 특성(재질, 탈 종류)에 영향을 받고 있었다. 본 연구를 토대로 향후 하회탈 관련 문화상품 개발시 5가지 감성적 요인을 고려한다면 소비자의 니즈에 부합하는 제품 디자인 개발이 이루어질 것이다.

The objectives of this paper are to study the effect of key parameters on the cycle performance and capacity and to estimate the cost of latent and sensible energy transportation systems. The overall conductance (UA) of each component, the ambient temperature and the absorber inlet temperature are considered the key parameters. It is concluded that COP of the solution transportation using an absorption system (STA) at ambient temperature is 10% higher than that of the conventional sensible system. It is also found that the cost of STA system can be reduced 7.5 times to that of sensible energy transportation for one year of operation with 10 km transportation distance.

All kinds of artwork, including multimedia and digital image that has been subliminated into an af mediating two numbers 0 and 1 in recent age, are self-sufficient and autonomous in themselves. Nevertheless, each of those artworks can be realized as a real entity only if its appreciator is capable enough to explore some potential meaning out of it through his or her own perceptual work. According to Mikel Dufrenne, an artwork is composed of three existential tiers: "le sensible" or the sensible material; "fe representation" or the subject(le sujet), and "1′expression." Dufrenne contends that our esthetic perception can be realized by way of three steps that are comparable to those three tiers: perception of the presence of the body("le sensible"), contemplative perception by way of imagination("le representation"), and reflective perception ("1′expression") as a result of dialectics of sense and sensibility. This paper argues on the aesthetic perception with regard to digital image expressed by two numbers 0 and 1, putting focus on the epistemological role of sensibility(감) that explores "1′expression" a la Dufrenne.

For the Designing a Dedicated Outdoor Air System with Ceiling Radiant Cooling Panels the concept of a dedicated outdoor air system(DOAS) with parallel sensible cooling was born from the decoupled system concept, which can be summarized as decoupling of ventilation and air-conditioning functions, or decoupling of sensible and latent load functions. First , remove the latent loads from the outside air(OA) intake and generated in spaces using a 100% OA ventilation system(i.e., DOAS). Second, remove the space sensible loads using a parallel mechanical cooling system, such as fan coil units, conventional variable air volume , and ceiling radiant cooling panel(CRCP) independent of the ventilation system.

A refrigeration dehumidifier with a recuperative heat exchanger is theoretically analyzed. The recuperative heat exchanger is located between the two air streams from and to the dehumidifying coil, and reduces the sensible heat load in dehumidification process. A simple model is developed to predict performance of the dehumidifier. The model predicts that the recuperative heat exchanger is effective especially in the low humidity condition, where the sensible heat load is relatively large. It is predicted that, by adopting a recuperative heat exchanger, a maximum 30~110% increase in COP is possible for indoor air at $27^{\circ}C$, and 40~60% relative humidity.

A numerical study on the cylindrical packed bed sensible heat storage unit was accomplished by finite difference method. Relation between the heat storage rate and the mechanical pumping energy and the characteristics of the heat storage were investigated for various in let velocities and porosities. In this study, the numerical results are as follows: 1) The temperature distributions of solid and fluid rapidly reached the steady state as the heat capacity ratio was increased. 2) The efficiency of the heat storage was increased as the heat capacity ratio was decreased. For constant heat capacity ratio, however, the efficiency of the heat storage was increased at lower porosity. 3) It is very profitable to design the heat storage system such that the porosity is larger for the large flow rate and samller for small flow rate.
