Pine mushroom (Songyi, Tricholoma matsutake (S. Ito et Imai) Sing.) industry in Korea has confronted with several difficulties in the light of marketing, i.e. its supply quantity, quality, price and promotion. In this essay we discussed the problems with four topics related to the mushroom: long term decreasing production by 7% per year, relatively dropping quality and prices in changing Japanese markets that import the mushroom from 11 contries and needed promotion. For these, we suggest first that pine mushroom production forests be managed on a sustainable basis in the present production sites. Second, harvesting and packing need to be done at the production sites so that its quality may not be damaged. Third, it should be understood that pine mushroom markets in Japan have been greatly changed. That is, Korea supply only 10% of Japanese pine mushroom impact. Forth, our own brand names for pine mushroom need to be developed. For solve these problems our critical and creative efforts and needed.

사례-대조 연구에서 처리효과를 나타내는 오즈비에 관한 일반적인 추론과 로짓모형을 이용한 통계적 추론을 고찰한다. 사례-대조 연구에서 오즈비의 측정오차에 기인한 편의, 추정된 오즈비로부터 약한 연관성을 검출하는데 문제점, 사례군과 대조군을 구성할 때 실험단위들의 상이한 참여비율 등이 오즈비에 어떤 영향을 미치는가 등을 논한다. We consider the general statistical inferences of odds ratio in case-control studies and logit medels for further inferences. We also discuss the biases of odds ratio due to measurement errors, weak association, differential participation rates.

This study was performed to investigate the strength characterstics of steel fiber reinforced recycled aggregate concrete. Test specimens were prepared with compressive, split tensile, flexural specimens and tested by ultimate strength. A superplasticizer and fly-ash were added to the mix to improve performance of recycled concrete. Test-variables are substitution of recycled aggregate(0, 30, 50%), steel fiber length(0, 30, 50, 60mm), steel fiber content(0, 0.5, 1.0, 1.5%). Test-specimen were classified by test-variables. The experimental results on the various engineering properties of steel fiber reinforced recycled aggregate concrete using waste concrete are summarized as follows. It was found that the compressive and split tensile strength were proportionally affected by quantities of recycled aggregate substitutions, but flexural strength wasn't. The maximum compressive strength was 392 kgf/㎠( series 4 : R30 L30 V1.0 A20 ), the maximun split tensile strength was 40 kgf/㎠( series 7 : R30 L30 V1.5 A20) and the maximum flexural strength was 62 kgf/㎠( series 7 : R30 L30 V1.5 A20 ).

김대섭,구자성,양재헌 우석대학교 생명과학연구소 1998 생명과학연구소 논문집 Vol.2 No.-

Cefradine, first generation cephalosporins, is a water soluble antibiotic agent. We prepared the alginate beads containing cefradine for developing release and evaluated the dissolutions of cefradine from beads. Cefradine was encapsulated into inner water phase of W/O/W emulsion beads which were prepared by cross-linking of alginate with Ca^2+. The delayed release patterns of cefradine for W/O/W emulsion beads were observed as it was compared with alginate simple beads without oil phase. As a results, W/O/W multiple emulsion beads could be use a controlled release DDS of water soluble agents such as cefradine. Also chitosan of high M.W could be a good intermediator of controlled release DDS.
