Two stacks of 25 mm thick black locust boards were air-dried during summer in Daejeon. Boards were stacked with conventional stickers and moisture pallets made of plywoods and stickers. In early stage the drying rates of the moisture pallet stack were lower than those of the sticker stack. but after 90 days the moisture content difference between two stacks was only 0.8 %. It implies that the moisture pallet stacking is effective to reduce surface checking usually occurring at the beginning of drying. but unfortunately which hasn’t been proven with thin black locust boards of 25mm thick. Number of the boards with end checks in the sticker stack were twice as many as in the moisture pallet stack. Steady-state moisture diffusion coefficient of 15mm thick black locust boards were measured by vapormeter cup method and compared with those of white oak. Steady-state diffusion coefficient of black locust in radial direction is cose to that in tangential direction. while those values are. respectively, 1/7 and 1/4 of oak ’ s.

Liquid ammonia treatment known as the most effective Wood plasticization method, was applied to two typical domestic species, Pinus densiflora, Castanea crenata. Small specimens of 30mm width, 300mm length and two thicknesses, 5 or l0mm, were used. For 5mm thick Specimens, Pinus densiflora was quite well plasticized after 4 hour liquid ammonia treatment, while Castanea crenata was not plasticized even after 24 hour treatment. Specimens of l0mm thick Pinus densiflora were hardly plasticized, but those with kerfs were bent somewhat easily. With the increase of liquid ammonia treatment time the thermal conductivity of Pinus densiflora increased, while that of Castanea crenata didn't. Presteaming before liquid ammonia treatment didn't improve the plasticization of both species.<br/> keywords: Pinus densiflora, Castanea crenata, liquid ammomia, thermal conductivity, plasticization,<br/>

Steaming has been used for bending wood for a long time, but the steam-bent wood is subject to spring-back and a relatively large radius of curvature. Liquid ammonia is known as an excellent wood plasticizer swelling both crystal and amorphous cellulose. Liquid ammonia technique for wood plasticization was developed and applied for bending alder and padauk pieces, which were used as parts of wooden furniture. The study confirmed that liquid ammonia bent wood can be used for various wood working design.<br/>

처리 온도에 따른 90 ${\times}$ 90 mm 낙엽송 각재의 재색 차이 조사

To make value-added products from small-diameter larch logs it is necessary to reduce the color variation between boards. The effect of heat treatment on the color variation was investigated. Four hundred air-dried larch squares were visually classified into six groups. The largest color difference index between them was 8.8. When they were kiln-dried lower than $120^{\circ}C$, their average color difference indexes decreased to less than 6.0 compared with the air-dried. However statistical analyses revealed that kiln-drying largely increased the variation of the indexes of the color elements. Heat-treatment above $150^{\circ}C$ increased the color difference indexes with the increase of temperature. The variation of color difference indexes within a group at $190^{\circ}C$ were less than the groups at $150^{\circ}C$ and $170^{\circ}C$. It implies that heat treatment at $190^{\circ}C$ could make the color of larch squares uniform.

청각장애노인의 생활실태와 사회복지서비스 욕구에 관한 연구

양점도(Yang, Jum Do),고강호(Koh, Kang Ho),박애선(Park, Ae Sun) 한국복지행정학회 2009 복지행정논총 Vol.19 No.1

본 연구는 청각장애노인의 전반적인 생활실태와 사회복지서비스 욕구를 조사하여 청각장애노인을 위한 사회복지서비스 지원 및 정책 마련에 필요한 기초자료를 제공하는데 목적이 있다. 본 연구의 자료수집은 대구청각·언어장애인복지관에서 2006년도에 실시한 ‘대구지역 청각·언어장애노인 실태 및 복지욕구 조사보고서’ 자료를 활용하여 재분석하였다. 연구결과, 청각장애노인들은 무료진료, 물리치료, 무료건강검진, 보장구 수리 및 지원, 건강상담, 건강강좌, 방문간호지원서비스에 대한 욕구가 높게 나타난 반면, 한문/일어/중국어 교실, 한글교육, 교양강좌, 컴퓨터교실, 문화강좌 서비스에 대한 욕구는 상대적으로 낮았다. 즉, 의료적 서비스에 대한 욕구는 강한 반면, 교육 및 여가지원서비스에 대한 욕구는 낮은 것으로 볼 수 있다. 청각장애노인의 성별과 연령, 장애등급과 실청시기에 따른 사회복지서비스 욕구를 살펴보면, 성별에서는 어르신모임, 한글교육, 한문/일어/중국어 교실 서비스, 연령에서는 도서대여, 안부전화, 생신잔치, 소풍나들이, 체육대회, 취업알선 서비스, 장애등급에서는 무료 이․미용, 무료급식, 건강상담, 무료건강검진, 한글교육 서비스, 실청시기에서는 어버이날 행사, 무료진료, 후원금(결연)지원, 저소득가정 물품지원, 한글교육, 취미교실 서비스에서 유의한 차이가 나타났다. 따라서 향후 청각장애노인에 대한 효과적인 예방과 개입의 전략을 수립하는데 있어서는 청각장애노인의 성별, 연령, 장애등급, 실청시기를 고려해야 한다. This study aims to offer the necessary basic data for the support of social welfare services and the preparation of policies for the hearing impaired elderly by researching the overall current livelihood and the desire for social welfare services of the hearing impaired elderly. As regards data collection, the study utilized and re-analyzed “The investigative report of the current conditions and desire for welfare of the deaf and the speech disordered elderly in Daegu” conducted in 2006 by the Daegu Rehabilitation Center for the Deaf and the Speech Disordered. As a result it is shown that the hearing impaired elderly had a higher desire for free medical service, physical therapy, free medical checkup, the repair and support of assistive devices, consultations on health, presentations about health, and a home nursing support service. Meanwhile, their desire for Chinese character/Japanese/Chinese classes, Korean language education, culture lectures, computer class, and community lecture services was relatively low. To put it another way, their desire for medical services was high, whereas their desire for education and leisure support services was low. In taking a look at their desire for social welfare services according to their gender, age, disability level, and the period of hearing loss, the results include the following: According to gender, there were significant differences in the senior s gathering, Korean language education, and Chinese character/Japanese/Chinese classes. According to age, there were significant differences in book borrowing, hello calls, birthday parties, picnics, sports days, and job brokerage services. According to disability level, there were significant differences in free shavings and haircut, free meals, consultations on health, free medical checkup, and Korean language education service. According to the period of hearing loss, there were significant differences in the Parents Day event, free medical service, aid (forming sponsorship) support, the supply of goods to low income families, Korean language education, and the service of a class for hobbies. Therefore, in establishing effective prevention and intervention strategies for the hearing impaired elderly, it is necessary to take into consideration their gender, age, disability level, and the period of hearing loss.

Furniture ststistics in Korean households and consumer preference to furniture styles were surveyed by a direct visit method. Four major cities in this country were selected From each city two hundred housewives living in apartments were sampled. They were generally considered to represent the middle class of this country.<br/> Most furnitures in households had been purchased later than 1990. Only half of the respondents were satisfied with their furnitures. It was found that consumers primarily emphasized on furniture design when purchasing it. Aout half of the respondents were possessing solid-wood furniture and 15% wanted to buy it. Most respondents well recognized the use of built-in furniture and DIY furniture.<br/> <br/>
