This study was conducted to clarify the hydrological characteristics of subsurface flow through a soil matrix and macropores. The research facility was set up in a 20m-1ong trench excavated down to bedrock at the base of a hillslope in the Panola catchment under USGS Georgia district. 13 macropores were found on the trench face and 6 major macropores were monitored. Matrix and macropore flow were measured during 95.5mm rainfall on March, 6 to 7. 1996. Macropore flow had great influence on formation of peak flow because the delivery time to Peak flow of macropore flow were faster about 10hrs than those of matrix flow. Matrix flow continued to recess for 3 days. On the other hand, macropore flow stopped within 12hrs after the event ceased. This means that matrix flow controls the recession part. The spatial variations of matrix and macropore flow between each trough and collector were very large by a wide range of 8,655.3 $\ell$ to 17.8 $\ell$ . The bed rock surface topography relates closer with the spatial variations of the flow than the surface one.

The purpose of this study was to measure the changes in soil properties and forest vegetation after surface fire, which had occured on June 5, 1983 in Mt. Gwanag, Kyunggi-do. Moisture content, organic matter and acidity of soil increased just after the fire and then dropped down up to those of unfired areas as time goes. Also total nitrogen, available phosphorous exchangeable base had the similar trend to moisture, organic matter and acidity. Most of the exchangeable bases in surface soil except for sodium were higher than those in sub-soil. No changes in soil texture by the fire were found. Increasers, decreasers, invaders and neutral species could be classified according to the relative importance value of each species. Species diversity was reduced just after the fire and increased gradually afterward. Diversity in the southeast slope was higher than that in the southwest slope. Due to the fire, evenness of woody plants decreased continuously while that of herbs increased. Species similarity was shown greater at fired areas than at unfired areas.

본 논문의 연구목적은, 우리나라 감자재배지역의 분포 특징과 그 중심지를 밝혀 보는데 있다. 이와 같은 목적을 위하여 감자가 외국에서 우리나라에 전파해온 경로와 한국 내에서 의 전파경로를 알아보고, 7개 지역의 감자재배지역의 특징, 우리나라 감자재배의 생산량, 재배면적, 재배농가, 각 시기별 감자 재배지의 중심지와 남한의 감자재배 중심지를 구하였다. 이와 같은 연구내용은 주어진 자연환경에 인간이 어떻게 적응해가면서 살아가는지를 공부하는 지리학의 전통적인 개념인 자연과 인간과의 관계를 이해하는데 도움을 줄 수 있을 뿐만 아니라, 초 중등학교 및 대학에서 공부하는 한국지리 교육과정의 학습자료로서 유용하게 쓰일 수 있을 것으로 기대한다. 연구방법은 문헌연구과 1970년부터 1995년까지의 전국의 시.군별 감자재배지역의 입지계수를 구하여 연구하였다. 그 결과를 요약하면 다음과 같다. 1. 감자가 한국에 처음으로 재배된 것은 1824년(조선조 순조24년) 인데, 전파과정을 살펴보면, 안데스산지의 페루(1500년대) $\longrightarrow$ 에스파냐(1532년) $\longrightarrow$ 중국(1650년) $\longrightarrow$ 한국(1824년)순으로 전파되어온 북방전래설과 영국의 감자가 1832년 충청도의 서산으로, 일본 감자가 1920년에 수원으로 전파되었다는 남방전래설이 있다 2. 감자는 한국 전 지역에서 재배되는 중요 농작물이다 그러나 우리나라의 지형이 남북으로 깊게 뻗은 반도국이므로 위도와 지형 차이에 따라 기온과 고도가 다르게 나타나는데, 이러한 자연적인 요인의 영향이 가장 큰 요인이 되어 고랭지 여름재배지역.중산간 봄재배지역.중부평야 봄재배지역 남부평야 봄재배지역 남부해안 2기작 재배지역.남부 겨울재배지역.제주 가을 월동재배지역 등 7개 지역으로 구분되어 재배된다. 3. 우리나라(남한)의 감자 재배지의 중심지는 강원도 고랭지 여름재배지역과 제주도 가을 월동재배지역, 소백산맥과 진안고원이 만나는 부근 산지지역의 남원군.구례군 거창군.고령군과 남해안의 밀양군.양산군이다. 강원도 지역과 제주도 두지역이 전테 재배면적의 52%를 점유하여 감자 재배지의 핵심지를 이룬다. 4. 한국 감자 재배지역 중심지의 지리적 특징은, 높은 산지지역의 산록완사면에 밭작물로 재배된다는 점과 교통이 불편한 지역으로서 도시화와 산업화 지역의 그늘 지역이 대부분이다. 강원도의 감자 재배지는 감자재배에 적합한 자연환경과 화전농업의 전통, 감자 재배기술의 전파, 중앙정부와 지방정부가 지원하는 각종 연구소 분포와 영농지도, 씨감자 생산과 협동조합의 판로 개척, 도로 개설과 포장 등의 인문지리적 요인이 영농조건을 개선하고 감자 판매를 위한 시장접근을 용이하게 하여, 남한 최대의 감자 재배지역을 형성하였다. 제주도는 산지지형과 따뜻한 기온으로 2기작이 가능하고, 감자가공 공장설립과 교통발달에 따른 육지 시장과의 접근이 용이해졌기 때문에 남한에서 2번째로 큰 감자재배지역이 되었다.(요약 및 결론에서 발췌)

The basaltic rocks of Daljeon-ri columnar joint (Natural Monuments # 415) and Noeseongsan Noerok site (Natural Monuments # 547) were analysed in order to understand basalt types of two areas. The basaltic rocks of the Pohang Daljeon-ri columnar joint show a typical porphyritic texture containing phenocrysts (olivine and clinopyroxene) and groundmasses composed of clinopyroxene, plagioclase, and opaque minerals,. In contrast, basaltic rocks of Noeseongsan Noerok are characterized by fine-grained groundmass with large phenocrysts of plagioclase. Other analysis such as magnetic susceptibility, X-ray diffraction and X-ray fluorescence also support the petrological differences of two basalt rocks. The Daljeon-ri basaltic rocks are plotted on phonotephrite volcanic rocks of alkaline series in TAS(total alkali silica), and on within plate basalt in Zr-Ti diagram. The Noeseongsan basalts, on the other hand, are plotted on basaltic andesite to andesite of sub-alkaline series in TAS, and on volcanic arc basalt in Zr-Ti diagram. These results indicate that the original mantle materials between two basalt rocks were different each other, which probably originated from the change of a tectonic setting in the southeastern Korean peninsula during the Miocene.

일반적으로 자갈하천의 하상에는 여울, 소의 연쇄 구조(Riffle-pool sequences)가 발생한다. 여울은 수심이 얕아 유속이 빠른 부분이고 소는 수심이 깊어 유속이 느린 부분에 해당한다. 여울과 소의 연쇄구조는 모래하천에서는 보이지 않는데, 여울에서는 빠른 유속으로 인하여 하상의 조립화가 진행되며, 반대로 소에서는 하상이 세립토로 구성된다. 그리고 여울은 하도의 경사에 따라 발생하며, 유속의 빠름과 느림에 따라 크게 평여울과 급여울로 구분할 수 있다. 본 연구의 대상하천인 양양 남대천은 국내에서는 보기 드물게 개발이 거의 되어있지 않으며 조사대상 구간인 어성전(법수치) 계곡을 포함한 양양 남대천 상류 약 0.4 km은 산지하천 구간으로 비교적 자연하천의 상태를 유지하고 있다. 본 연구는 자갈하천의 구간에서 연속적으로 발생하는 여울, 소를 대상으로 하상경사, 하상재료, 수심, 유속 등 물리적 특성을 조사하였다. 이 구간에서의 나타난 여울 구간은 11개소로 구분할 수 있으며, 급여울이 시작되는 구간에서부터 여울과 소는 반복적인 형태로 나타났다. 하상경사는 평여울 구간에서 0.0011-0.0057, 급여울 구간에서 0.0143-0.0201로 나타났다. 하상재료는 $D_{50}$의 경우 평여울 구간에서 3.66-4.63 mm, 급여울 구간에서 3.61-4.63 mm로 나타났다. 이와 같은 연구는 자연하천이 갖는 여울, 소 연쇄구조의 물리적 특성을 이해하고, 자연형 여울, 소를 조성하거나 복원 시 설계를 위한 기초자료로 활용될 것으로 기대된다.

To catch the relative importance of varietal and environmental variation in various grain quality components associated with palatability of cooked rice, grain appearance, milling recovery, several physicochemical properties of milled rice and texture or eating quality of cooked rice for rice materials of five japonica cultivars, produced at four locations of the mid-mountainous and alpine area of Korea in 1989, were evaluated and analyzed the obtained data. Highly significant varietal and locational variations were detected in 1000-grain weight, amylose content, K/Mg ratio, gelatinization temperature, peak viscosity, breakdown and setback viscosities as compared with variety x location interaction variation. Also, marked locational variations were recongnized in milling recovery from rough to brwon rice, alkali digestibility and protein content, and significant varietal variation was caught in stickiness /hardness ratio of cooked rice. The variety x location interaction variation was especially large in quality components of grain appearance and ripening, palatability of cooked rice and consistency viscosity. One thousand kernel weight was heaviest in Jinbuolbyeo and Odaebyeo, and the unfilled grain ratio was lowest in Jinbuolbyeo. Odaebyeo showed slightly' lower ratio of intact and clear milled rice because of more chalky rice kernels compared with other cultivars. Amylose content of Jinbuolbyeo and Sobaegbyeo was about 1% lower than that of others and K/Mg ratio of Odaebyeo was the lowest one among rice materials. Odaebyeo, Sobaegbyeo and Jinbuolbyeo revealed significantly low gelatinization temperature and setback viscosity while high peak and breakdown viscosities. Cholwon rice showed the greatest kernel weight, good grain filling but lowest ratio of intact and clear milled rice while Jinbu rices exhibited the highest milling recovery from rough to brown rice and ratio of sound milled rice. Amylose content of milled rice in Jinbu rices was about 2-3% lower than those in other locations. Protein content of polished rice was about 1% lower in rice materials of middle zone than those of southern part of Korea. K/Mg ratio of milled rice was highest in Jinbu rice and potassium content was slightly higher in the rice materials of middle region than in those of southern region. Alkali digestion value and gelatinization temperature of polished rice was markedly high in Jinbu rices as compared with other locations. Breakdown viscosity was hightest in Chlown rices and next higher with the order of Hwaso>Unbong>Jinbu rices, and setback viscosity was the quite contrary tendency with breakdown. The stickiness /hardness ratio of cooked rice was relatively higher value in Cholwon rices than in the others and the palatability of cooked rice was a little better in Unbong and Cholwon rices than in Jinbu and Hwaso rices, although variety x location interaction variation was large. The rice materials can be classified largely into two groups of Jinbu and the others by the distribution on the plane of 1st and 2nd principal components (about 60% of total informations) contracted from twelve grain quality properties closely associated with eating quality of cooked rice. Also, Jinbu and the other rices were divided into two and three rice groups respectively. Varietal variation of overall rice quality was smallest in Hwaso. The most superior rice group in overall quality evaluation included Odaebyeo produced at Cholwon, Unbong and Hwaso, and Sobaegbyeo grown at Unbong

Grading of the urushi lacquer is quite difficult because of large variations depending on origin, growing conditions, time acquisition, storage conditions. It is urgently required to establish a grading system of urushi lacquer by combining traditional method with scientific methods. Traditional grading of urushi lacquer was done by visual inspection of 10 experts who are working on urushi lacquer industry. Common aspects of the experts were color, odor, viscosity, spread properties on Hanji, color and drying properties on glass based the traditional grading system. In addition, rubbing on Hannj and heating with alcohol lamp was also used to grade urushi lacquer. The grading results of 10 experts showed that chinese urushi lacquer (E) of 7.03, japanese urushi lacquer (C) of 6.84, domestic urushi lacquer of (A) of 6.41 and another chinese urushi lacquer (D) of 5.27, and domestic urushi lacquer (B) of 2.50 in descending order. The degree of spread on Hanji was not consistent among 10 experts. These results indicated that the traditional grading system was pretty much personal and required of developing more objective method based on scientific background.

본 연구는 도시화에 수반되는 지하수의 수문황경 변화를 조사하기 위해, 일본 하다노 분지를 대상으로 수문지질을 밝히고, 인위적인 요인에 의한 수문환경 변화와 수문특성을 종합적으로 분석하였다. 그 결과, 분지의 대수층은 퇴적환경에 의해 TP층을 경계로 신기 loam층과 고기 loam층으로 나눌 수 있으며, 전자를 천층지하수의 대수층, 후자를 심층지하수의 대수층으로 구분할 수 있다. 그리고 대수층의 기저기복은 지하수 수위의 공간적 차이를 유발하고, 지하수 유동계에 큰 영향을 미치고 있다. 분지의 심층지하수의 주요 공급원은 탄자와 산지의 지표수이고, 천층지하수는 분지 내에 내리는 빗물에 기인한 것으로 간주된다. 지하수의 과잉양수는 지하수 수지의 불균형을 유발함으로서 심층지하수가 매년 0.12~0.14m씩 저하되고 있다. 대체로 Cl-, NO3-농도는 심층지하수보다 천층지하수에서 높으며, 선정부에서 선단부로 갈수록 높아지는 것으로 보아 분지의 지하수 수질형성에 인위적인 요인이 크게 작용하고 있는 것으로 사료된다. 지하수의 화학적 조성은 대체로 Ca(HCO3-)2형에 속한다.
