This study aims to determine the aspect of realization of `grammar inquiry activity` at the chalkface as examining a kind of activity unit in the textbook. Grammar inquiries in the middle school textbook were analyzed by type and were categorized by learning hierarchy. The course of study is as follows: The characteristics of activity-centered grammar unit were determined in the 2nd chapter. I determined the characteristics of detailed texts constructing `activities` of grammar unit, and organized functions of these detailed texts. Also, by its feature, I investigated that detailed text ensuring completeness of text is `activity text`. `Activity text` defined as the key element was categorized by type of thinking, and the meanings of its categories were investigated. `Activity text` embodied in eight kinds of textbooks was classified by seven types. However, activity that makes learners discover and understand lingustic immanent rules expansively is not enough.

Smartphone is integrated into the daily lives of all types of people not even young generation. A touch screen display is a primary input device of a smart phone, a tablet computer, etc. While there are many tough technologies in existence, resistive and capacitive are dominant and currently lead the touch screen panel industry. And a capacitive touch screen panel widely used in smart phones is coated with a material that stores electrical charges. In this study, we tried to manufacture gloves produced with electro-conducting leather as a tool to operate a touch panel screen. Therefore, electrically conductive materials, Polyaniline(PANI), Poly(3,4-ethylenedioxythiophene) (PEDOT), and Carbon nanotubes (CNT) were applied to the surface of leather to be used as a touching operator for capacitive touch screen panel. The leather samples were treated by simple painting method; firstly, they were painted with aqueous solution containing each of the electrically conductive materials and then dried. This cycle was repeated three times. Consequently, the treated leather samples showed electrical conductivity and reasonable working performance to the capacitive touch screen. And, PANI showed the best performance and highest electrical conductivity, and then PEDOT and, CNT in decreasing order. This is because the solubilities of PANI and PEDOT show higher than dispersibility of CNT. Thus, the concentration of conducting polymers was greater than that of CNT in the treating solutions.

The purpose of this study was to suggest a design of comfort snowboard protector that reflects consumer needs by using the methods of the Quality Function Deployment (QFD). First, the consumer demands (What) regarding the development of the protectors were selected through in-depth interviews. The importance rating of each selected demand (What) was assessed through a survey, and the product design elements were chosen through preceding studies and experts’ conferences. Finally, the absolute importance values were calculated using the importance rating and relationship matrix, and then used in the designing of the snowboard protector. Study results showed that fit, comfort, shock absorption, size, activity comfort, material, weight, cost, etc. were the demands in developing the snowboard protectors. The shock absorption and comfort were considered most important by 48.0% and 37% of the respondents, respectively. The shock absorption, moisture absorption, drying speed, moisture permeability, suitable size, activity comfort, etc. were selected as the product design elements. And then the result of developing the House of Quality showed that the application of a new thin material with superior shock absorption was required. Also, it was known that the development of a comfortable protector that does not hinder motion and easily emits perspiration was required. For this purpose, the design of a protector that applies 3D technology, adheres comfortably to the body during motion, and emits perspiration well is presented.

Ultra-fine fiber fabrics are relatively inexpensive, easy to care, soft to touch, and most of all, highly thermokeeping, making them widely used as winter bedding and clothing materials. However, consumers are concerned about their effects on respiratory organs in that fine fibers might be released from ultra-fine fiber products. Therefore, we selected four representative types of so-called ultra-fine fiber fabrics on the market and investigated their characteristics regarding fiber loss that might occur under a consumer’s use environment. Three types of samples were pile fabrics mostly used for winter items to keep warm. One type of sample was no-pile fabric mostly used for cleaning items such as towel, wiper, and so on. It was observed that diameters of fibers present in ultra-fine fiber fabrics were more than 10㎛ (1.0dtex). Overall, pile fabrics showed more fiber loss than no-pile fabrics. Among pile fabrics, thicker and straighter fibers had greater fiber loss from the fabrics in an environment with friction, pulling, and laundering. Meanwhile, thinner and wavier fibers produced more fibrous dusts during tumble drying.

To develop cool touch feeling fabrics for summer clothing material, it was manufactured several compositions of woven fabrics, having rayon multi-filament yarn (non-twisted) as warp and various kinds of yarn, such as viscose rayonmulti-filament yarn (twisted), tencel® spun yarn, PET high absorbance quick dry filament yarn, and PET based rayon-likeyarn, as weft. After preparing the fabrics, basic properties of the fabrics were investigated, such as air-permeability, tensile strength, absorption rate, drying rate, etc. Also, surface warm / cool sensations of the woven fabrics were assessed by Qmax Warm / Cool Touch Tester. It was observed that the fabrics composed of viscose rayon multi-filament yarn (warp)and PET high absorbance quick dry filament yarn (weft) showed excellent surface cool touch sensation-the highest Qmaxvalue. This is because the fabric having flat shaped PET high absorbance quick dry filament shows the largest contact areawith Qmax measuring plate. And, the fabric also showed superior high absorbance and quick dry property as expected. In addition, we treated phase change material (PCM) on the surface of the fabric composed of viscose rayon multi-filamentyarn (warp) and PET high absorbance quick dry filament yarn(weft) to improve the cool touch feeling. However, the surface cool touch feeling was impaired by resin treated with PCM during the finishing process.

지역개발의 자연환경 보존지역으로서 국립공원 활성화를 위한 영향변수의 구조적 관계

홍경화 ( Kyunghwa Hong ),김준호 ( Joonho Kim ) 전남대학교 지역개발연구소 2021 지역개발연구 Vol.53 No.2

생태관광은 대중관광의 부정적인 영향을 최소화하며, 자연환경 보존 및 지속 가능한 관광개발을 촉진시키고 있다. 이러한 관점에서 자연생태계 보존을 위한 대표적인 방안으로 국립공원이 지정되었다. 이에 본 연구는 국립공원 탐방객을 대상으로 생태관광에 대한 지각된 가치, 환경의식 및 행동의도의 영향관계를 통해 국립공원 활성화 방안을 제시하고자 하였다. 실증분석결과, 지각된 가치의 3개의 하위 요인인 기능적 가치, 인식적 가치, 감정적 가치는 행동의도에 유의한 영향관계를 미치는 것으로 나타났다. 또한, 환경의식은 국립공원 탐방객의 생태관광에 대한 지각된 가치의 기능적 가치, 인식적 가치와 행동의도의 영향관계에서 조절효과를 나타낸 반면, 감정적 가치와 행동의도에는 조절효과가 없는 것으로 나타났다. 이와 같은 결과는 국립공원 정책 담당자에게 자연환경 보존지역으로 국립공원 활성화를 위해 국립공원 탐방객이 찾아올 수 있는 다양한 프로그램 개발과 보존 정책 수립이 요구됨을 시사하고 있다. Ecotourism has been recognized as a tourism which not only minimizes negative effects of mass tourism but also promotes conservation of natural environment; furthermore, it can lead to sustainable tourism development. From this point of view, national parks have been designated as a place in order to conserve ecosystem. This study empirically examined the relationship among perceived value of ecotourism, environmental awareness, and behavioral intention of national park visitors to provide activation strategies for national parks. The empirical results demonstrated that three sub-factors of perceived value such as functional value, epistemic value, and emotional value had a direct positive influence on behavioral intention. The study, moreover, demonstrated that the relationship between functional value, epistemic value and behavioral intention was moderated by environmental awareness while emotional value competence did not. These results indicated that policy-makers are to conduct the various programs and establish conservational policies to national park visitors for invigorating national park as environment conservation area in regional development.
