In this paper the safety problems of bench grinder have been reported. The safety status of bench grinders in 169 companies in Kyungbuk province was investigated. It was found that the two most important safety problems are the improper installations of workrests and the use of side (instead of front) of the grinding wheels.

This study was carried out to identify the infection rate of common internal parasites according to the age and the incidence of single or mixed parasitic infections from outside rearing dog in Kyungbuk province. Fifty-one dogs in 4 dog rearing farms were examined, and fece samples of dog's were freshly collected from farm ground and rectum swabs. The results obtained from this study were summarized as follows ; 1. Out of 51 dogs examined, 9 dogs were infected with some helminths, and mean infection rate was 17.6%. 2. The frequently encountered helminths were Ancylostoma caninum and Trichuris vulpis (32.3%), Toxascaris leonina(16.7%), Dipylidium caninum(8.3%) and Isospora sp(8.3%), in order. Specially the prevalence of Toxascaris leonina was relatively high in this study than other reports, and its significance was discussed. 3. The infection rate in younger dogs was higher than that of older dogs, especially that of the dogs under 6 months old was 31.3%, 6 months to 1 year old dogs was 0.8%, and over 1 year old dogs was 18.2%, respectively. 4. Single infection rates with Ancylostoma cantnum, Trichuris vulpis, Toxascaris leonina, Dipylidium caninum and Isospora sp were 11.8%. But double infection rates with the Ancylostoma caninun plus Trichuris vulpis and Toxascars leonina was 5.8%.

For artificial cultivation of Phellinus baumii, we have conducted a study on cultural characteristics and condition of fruitbody formation in sawdust cultivation. Mycelial density and incubation rate were higher in oak sawdust+rice bran (4 : 1) medium than oak sawdust 100% medium. However, primordia and fruitbody formation were higher in oak sawdust 100% medium than rice bran added medium. Bigger bottle capacity (1,100 ml) resulted in a little higher yield and more biological efficiency than 850 ml bottle.

아라미드 섬유소재는 고강도, 고내열성의 소재로 다양한 용도전개가 가능하나, 일광 및 부식에 의한 내광성 및 내후성이 급격하게 저하되는 단점이 있다. 자외선의 광화학적 작용에 의해 변퇴, 경화, 취하, 강도저하가 일어나는 단점을 보완하기 위해 내광성 및 내화학성이 우수한 전이금속산화물 소재와의 복합화를 통해 내광성 및 내화학성 개선에 대하여 연구하였다. zinc acetate 수화물과 수산화리튬을 무수에탄올로 용해시킨 용액을 강하게 교반하여 나노 산화아연 졸을 제조하였다. 제조된 나노크기의 zinc oxide 입자의 형상과 입자분포 등 제조특성을 입도분석기, FE-SEM 및 EDS 분석을 통하여 고찰하였으며, 제조된 나노졸을 아라미드 섬유에 침지시켜 Xenon-arc 내후성시험기에서 80시간 동안 노출시켜 노출시간에 따른 물성변화를 분석하였다. 나노졸을 5~20% 픽업으로 패딩한 후 광에 노출된 아라미드의 인장강도는 나노졸을 처리하지 않은 아라미드 섬유보다 20~30% 개선된 인장강도를 나타내었다.

This study was undertaken to compare the obesity related dietary factors among rural middle school students living in the Daegu.Kyungbuk area. Anthropometric data showed that mean height and weight were 162.7$\pm$8.6cm and 53.9$\pm$9.8kg in 220 male students and 158.4$\pm$6.2cm and 51.0$\pm$7.6kg in 210 female student. Mean BMIs for boys and girls were 19.00$\pm$2.35 and 19.30$\pm$2.45, respectively. 71.36% of male students and 71.9% of female students were underweight by the BMI index. Students who skipped the breakfast were up to 66.8%. The reasons for skipping a meal for both sexes were significantly different. Compared to males, more female respondents felt guilty and depressed related to eating. Furthermore, females were more significantly concerned about body image, diet and body weight (p<0.001), and they were not satisfied with their weight. The sources of information on obesity and diet were radio and TV in males, while females gathered information from magazines and friends. The ideal body weight of male students was heavier than the actual body weight while female students desired a thinner body shape. In conclusion, a different approach for nutrition education based on sex should be developed, and implemented fur adolescents.
