임동옥 호남대학교 2002 호남대학교 학술논문집 Vol.23 No.2

목재의 해부학적 데이터는 19C 다수 연구자에 의해 분류 목적으로 이용되었고 (Kiese,1851:de Candolle,1818,Hartig,1859: Sanio,1863), 특히 해부학적 증거들은 현대 분류체계에도 많이 적용되고 있다(Takhtajan,1980; Thorne,1976;Cronquist, 1968). 국내에서 목재해부를 통한 계통분류학적인 연구는 나자식물과 피자식물의 몇 과에서 보고된바 있다(소와 이, 1982; 소,1983, 1986; 박, 1983; 소와 박,1984, 1985; 박과 소, 1984). 목재로 만든 가구, 도구 및 건축물들을 구성하는 목재를 정확하게 동정하는 데 비교목재해부학적 결과는 몇몇 목재 샘플을 동정하는데 도움을 주고 있다(Carlquist, 1988; 임과 소, 1986, 1991a, b, 1993; 소와 임, 1987). 목재 해부학적 데이터의 또 다른 적용은 약용식물 판별 (Trease and Evans, 1972). 식품 대체품의 판별 (Winton, 1916), 동물 먹이습성 (Cutter, 1969). 고생물학적 목재의 연구 (park, 1997),목재 생산 (Cutler. 1978), 연륜연대학을 이용한 고기후 파악(Suzuki, 1995; park and Kim, 1998)그리고 법적 판례 (Cutler 1978) 등에 이용된다. The application of wood anatomical diversity for classification of plants has been mentioned by many workers (Kieser, 1815; de Candolle 1818: Hartig.1859;Sanio,1863).Evidencc fron wood anatomy are largely employed in mordern systems of systematics (Takhtajan, 1980; Thorne, 1976; Cronquist, 1968; Soh & Lee, 1982; Soh, 1983, 1986; Park, 11983; Soh & Park. 1984, 1985; Park & Soh, 1984). Accumulated knowledge in comparative wood anatomy has helped in identification of several timber samples (Carlquist, 1988; Lim & Soh, 1986, 1991a, b, 1993; Soh & Lim, 1987; Lim, 1997). Another use of wood anatomical dates have been applied medicinal plants (Trease and Evan, 1972), food adulterants and contaminants(SWWintom, 1916), animal feeding habits (Cutter, 1969), studyof archaeological wood (park,1997), wood products (Cutler, 1978), dendrochronological use of wood (Suzuki, 1995; Pard and Kim, 1998) and forensic works (Cutlllller 1978).

임흥빈,강영국,손형옥,이영구,문자영,이동욱 충북대학교 엽연초연구소 2001 煙草硏究 Vol.18 No.-

This study was conducted to measure and compare the salivary cotinine concentration between smokers and nonsmokers, and to investigate the effect on the exposure to environmental tobacco smoke(ETS) with housewives, living on an apartment of Korea. Saliva samples were taken from all volunteers and salivary cotinine was analyzed by a developed radioimmunoassay(RIA) method. The median salivary cotinine levels were 52.8±12.6 ng/ml and 44.6± 9.7 ng/ml in male smokers and in female ones, respectively, and they were 4.3±2.1 ng/ml and 2.9±3.1 ng/ml in male nonsmokers and in female ones, respectively. In addition, average salivary cotinine levels were 3.8±2.7 ng/ml in housewives from smoking homes and 2.4±2.4ng/ml in ones from nonsmoking homes. Results obtained from the analysis of salivary cotinine demonstrate that smokers had a significantly higher concentration of salivary cotinine than nonsmoker. But, there was no significant difference in the salivary cotinine concentration for housewives living in apartment between with smoking husband and with nonsmoking husband.

한국산 고로쇠나무와 거제수나무에서 효율적인 수액 채취를 위한 연구. I. 2기목부의 해부

임동옥 湖南大學校 1997 호남대학교 학술논문집 Vol.18 No.2

고로쇠나무와 거제수나무 수간의 해부학적 특징을 관찰하였다. 고로쇠나무의 2기목부는 산공재이고, 각상의 도관이 2-3세포씩 방사복합배열을 하거나 단독분포하였으며, 도관요소의 측벽에 호생벽공과 나선비후, 말단벽은 단천공이고, 대상의 이관 주축유조직과 인피상 섬유 및 동성 Ⅰ형인 방사조직이 나타났다. 거제수나무의 재는 각상 도관이 방사복합배열 또는 단독분포한 산공재이나 도관요소의 말단벽은 계단상천공이고 측벽무늬는 호생벽공이며, 방사조직은 이성 Ⅱ형의 특징을 보였다. 따라서 도관요소 측벽에 나선비후와 말단벽이 둔각이고 단천공이며, 동성Ⅰ형인 방사조직의 특징을 갖는 고로쇠나무가 거제수나무보다 더 특수화 된 것으로 사료된다. Anatomical study of the stem wood was carried out Acer mono and Betula costata grown in Korea. Wood of Acer mono has diffuse porous and shows angular vessels in radial multiple of 2-3 cells or solitary, alternate pitting simple perforation plate, spiral trickening, apotracheal banded parenchyma and libriform fibers. in addition, its ray is homogeneous type I with only procumbent ray cell. Diffuse porous wood of Betula costata shows angular vessels in radial multiple of 2-3 cells or solitary, alternate pitting. scalariform perforation plate, and heterogeneous type II ray. On the basis of arrangement, shape, length and diameter of vessel element, the angle of end wall to vessel axis, and ray type, wood of Acer mono has spiral thickening, large angle and homogeneous type Ⅰ, shows more specialization characters than that of Betula costata.

SM45C의 Laser 표면개질 조건에 따른 마멸특성에 관한 연구

옥철호,임동욱,서영백,박흥식,전태옥 동아대학교 생산기술연구소 2000 生産技術硏究所硏究論文集 Vol.5 No.1

Surface modification of plain carbon steel (SM45C) by Laser are usually much finer and stronger than the base metals. Nd-YAG laser source changes and refines the microstructure of the near surface layer, leading to enhanced hardness and wear resistance. The present study was undertaken to investigate the wear behavior and a processing parameters such as, power density, pulse width, defocusing distance, and molten depth for surface modification. The wear test was carried out under different experimental condition using the wear test device and the annular surfaces of wear test specimens as well as mating specimen of alumina ceramics(Al_2O_3) was rubbed in dry sliding condition. The results show that molten depth and width depend on defocusing distance. The wear loss was much in lower speed range below 0.2m/sec and in higher speed range above 0.7m/sec, but It was little in intermediate speed range. It depends on oxidation and wear speed.

The distribution of hydrophytes and circumference vascular plants in Namdae basin were investigated. These plant were composed of 2 divisions, 4 classes, 32 orders, 68 families, 152 genera, 164 species, 1 subspecies, 23 varietas. Hydrophytes were divided emerged plant (35 spp.), free-floating plant(1sp.) Salvinianatans in Kigokli and Mujueup area, and submerged plant (2 spp.) Potamogeton crispus in sochonli, Kigokli and Mujueup area and Hydrilla verticillata in Kigokli and Mujueup area. The dominant species are Phragmites japonica in Kigokli area, and Rumex crispus, Juncus effusus var. decipiens and persicaria filiforme in Sochonli area. The hydrophytes examined collecting area respectively appear to be more many species in down stream -Mujueup(18 spp.), Kigokli (25 spp.) and Youngwhagyo (18 spp.) - than those in upper stream -sochonli (12 spp.), Simgokli (6 spp.), Baebangli (9spp.) and Gangdukli (13 spp.).

임동옥 호남대학교 산업기술연구소 1996 산업기술연구논문집 Vol.3 No.-

전라북도 고창군에 위치한 화실봉일대의 식물상과 녹지자연도의 등급을 분석하였다. 조사된 식물상은 2문 5강 39목 110과 346속 74변종 5품종 2아종으로 밝혀졌다. 본 조사지역의 식생은 식물분포학상 한국 남부아구에 속한다. 또한 난대형 식물인 실고사리가 서식하고 있었다. 녹지자연도의 등급은 0, 2, 6 그리고 7로 구분되었으며, 우점하는 자연도는 6으로 81.9%를 점유하였다. 운곡서원 주변에 내무부지정 보호수 1815 및 1816호의 느티나무 5그루가 있고, 보호대상 수종으로 측백나무 12그루(운곡리)와 느티나무 1그루(반암리)도 보호할 가치가 있다고 사료된다. The analysis in folra, vegetation and degree of green naturality(DGN) has been studied at the site of Whasilbong in Kochang-kun of Chonbuk province. The folra of Whasilbong consisted of 2 divisions, 5 classes, 39 orders, 110 families, 346 genera, 458 species, 74 variation, 5 forma and 2 subspecies. From the floristic point of view. Whasilbong belongs to the south province in Korea represented as Platicarya strobilacea, Cudrania tricuspidata, Lindera sp., Ilex sp., Halorrhagis micrantha and Cymbidium goeringii. And there are distributed Lygodium japonicum as warm temperate type. A degree of green naturality appear to divides 0, 2, 6, and 7. Dominant DGN was 6 and occupied about 81.9% respectively of the area investgated. The protective tree indicated from the Ministry of Home Afairs exist 5 trees of Zelkova serrata(No. 1815 and 1816) in circumference of the Ungok auditorium. It is considered that each one tree of Thuja orientalis in Ungokli and Zelkova serrata in Banamli were protective value.
