Conventional method of generating meteorological surfaces over geographic areas often neglects the elevation effect which is considered to be a single most important control over local climate. Deviation of the estimates may exrled practical limits at some areas with complex toprlgraphy. A digital map featuring coordinates and elevation data of 72 weather stations in Korea were joined with hourly weather(trmperature, relative humidity, precipitation and wind speed) observations at the stations by using a geographic information system software. An inverse distanre weighted interpolation was done on the point features to generate prim-itive meteorological and elevation surface grids consisting of 430×600 cells, respectively. Elevation difference at each cell between the United States Geological Survey's 1 km digital elevation model and this virtual ele-vation surface was calculated. Known relationships between meteorological elements and the elevation differ-ence were used to derive "correction grids" representing the potential effects of elevation difference at each grid cell. The correction grids were added or multiplied to the primitive meteorological surfaces to obtain ele-vation-corrected estimates for corresponding elements. This srheme was applied to hourly data of 27 March 1998 to generate the elevation-corrected mrteorological surfaces. Observed data of 350 automated weather sta-tions were used to partially validate the accuracy of the results. This simple scheme sHelved a feasibility of a near-real time generation of hourly meteorological surfaces for temperature and rainfall with an affordable error range.

産褥期 感染이란 分娩後 生殖器의 細菌에 의한 感染을 意味하며, 産後 體溫上昇의 大部分은 骨盤感染에 의한 것으로 産褥期 感染의 重要한 指漂가 된다. 한의학에서 産後發熱의 病因病耭는 주로 邪毒感染, 血瘀, 外感, 血虛 등으로 보았으며, 치료는 一般的으로 産後疾患에는 處證이 많아 發表攻裏를 過度하게 하지 않고, 氣血과 營衛의 調和에 위주로 하나, 外感과 裏實證을 疏怒히 하면 안된다. 따라서 産後發熱을 惹起하는 各種 原因菌에 對한 客觀的인 抑制效果의 檢證은 産後發熱의 治療率을 높이는데 중요하다. 그 결과 산욕기감염을 유발하는 各種 細菌에 對해 黃連, 烏梅, 五味子 등의 水溶性 抽出物이 杭菌活性이 相對的으로 좋은 效果를 보였다. 따라서 産褥期 感染의 治療에 이들 韓藥材를 이용하면 보다 效果的일 것으로 생각된다. Deparment of Oriental Medicine, Graduate School of Dongguk University, Major in Oriental Ob & Gy. Various kinds of medicinal herbs and prescribed herb medicines which have usually been used for treatment of reducing fever, purging intense heat, and detoxication were secreened for antibacterial activity against Proteus vulgaris, S. aureus, and E. faecalis which causing puerperal infection. Minimal inhibitory concentrations of water- and ethanol-soluble extracts of Hwangyon(C. japonica), Omae(P. mume), and Omiza(S. chinensis) were determined and using thin-layer chromatography the extracts of Hwangyon and Omiza were separated. The results obtained were as follows: 1. The water-soluble extracts of Keumeunhwa(L. japonica), Chiza(G. jasminoides), Hwangyon(C. japonica), Dansam(S. miltiorrhiza), Omae(P. mume) and Omiza(S. chinensis) showed antibacterial activities against P. vulgaris ; among them, the extracts of Hwangyon, Omae, and Omiza showed high antibacterial activities. The water-soluble extracts of Keumeunhwa(L. japonica), Hwangyon(C. japonica), Hwangkeum(S. baicalensis), Hwangbaek(P. amurense), Dansam(S. miltiorrhiza), Daehwang(R. coreanum), Omae(P. mume), Omiza(S, chinensis), Gingseng(P. ginseng), and Gamcho(G. uralensis) showed antibacterial activities against S. aureus ; among them, the extracts of Hwangyon and Omiza showed high antibacterial activities. The water-soluble extracts of Banggi(C. trilobus), Daehwang(R. coreanum), Omae(P. mume), Omiza(S. chinensis), and Gamcho(G. uralensis) inhibited the cell growth of E. faecalis ; among them, Omae and 0miza showed high antibacterial activities. The extract of Hwangyon(C. japonica) and Omae(P. mume) showed no inhibition against E. coli. However, the extract of Omiza(S. chinensis) inhibited cell growth of both E. coli and B. subtilis. 2. The water- and ethanol-soluble extract of Hwangyon(C. japonica) showed antibacterial activities against P. vulgaries and S. aureus, those of Omae(P. mume) against P. vulgaris and E. faecalis, and those of Omize(S. chinensis) against all species tested, P. vulgaris, S. aureus, and E. faecalis. With the exception that ethanol-soluble extract of Hwangyon(C. japonica) showed much higher antibacterial activity against S. aureus than water-soluble one, antibacterial activities of both water- and ethanol-soluble ones were similar to each of other two medicinal herbs. 3.When the prescribed herb medicines were tested, Sambohwan showed antibacterial activities against P. vulgaris and S. aureus. No prescribed herb medicine inhibited the cell growth of E. faecalis. 4. Minimal inhibitory concentrations(MICs) of both water- and ethanol-soluble extracts of Hwangyon (C. japonica), Omae(P. mume), and Omiza (S. chinensis) against P. vulgaris were 2.5㎎/㎖, 10㎎/㎖, and 20㎎/㎖, respectively. Those of both Hwangyon (C. japonica) and Omiza(S. chinensis) against S. aureus were 1.25㎎/㎖ and 10㎎/㎖, respectively. MICs of water-soluble extracts of Omae(P. mume) and Omiza(S. chinensis) aganist E. faecalis were 2.5㎎/㎖ and 5㎎/㎖, and those of ethanol-soluble extracts were 5㎎/㎖ and 10㎎/㎖, respectively. Except for those of E. faecalis, the cell growth of P. vulgaris and S. aureus were inhibited by much lower concentration of ethanol-soluble extracts used. As a result, the antibacterial compounds against P. vulgaris, S. aureus, and E. aecalis are contained in the extracts of Hwangyon(C, japonica), 0mae(P. mume), 0miza(S. chinensis), the prescribed herb medicine, Sambohwan, and might be used for treatment of puerperal infection. Further study should be carried out to identify which compounds affect the cell growth inhibition of P. vulgaris, S. aureus, and E. faecalis.

경북 양남지역의 제3기층내에 많은 밴토나이트광상이 분포되어있다. 이들 벤토나이트광상은 제3기의 전동층과 어일화산암류의 암층내에 배태되어 있으며 광상의 모암은 주로 안산암질의 화산암 및 화산쇠설성 퇴적암으로 되어있다. 이들 벤토나이트광상의 광체들은 주로 괴상으로 소규모로 나타나는 특징이 있다. 또 본 지역의 벤토나이트광상들은 단층선상이나 그 인접부에 분포하고 있어 광상의 형성과 단층과의 밀접한 관계가 있을 것으로 사료된다. 각 광상에서 산출되는 몬모릴로나이트의 광학적 특성과 그 수반광물이 모든 광물에 있어서 유사하게 나타난다. 몇몇 광산에 있어서 최상부층에 두껍게 피복된 안산암체가 부분적, 불규칙적으로 벤토나이트화 되어 있는 것이 관찰된다. 본 지역 벤토나이트광상의 산출상태를 여러가지 관점에서 검토한 결과 이들 벤토나이트광상은 단순한 숙성벽질작용만으로 형성되었다고 생각하기는 어려운 것 같다. 그래서 본 광상들은 단층과 같은 구조적 약대를 따라 이동된 열수 혹은 지하수등에 의한 모암의 변질효과도 관여하여 형성된 것으로 생각된다. Many bentonite deposit are distributed in the Tertiary rocks of the Yangnam area, Kyeongbod, Korea. These bentonite deposits occur in the Jeondong Formation and the Eoil Volcanics of the Tertiary, age and their origical rocks are mainly of andesitic volbanic rocks and pyroclastic sedimentary rocks. The ventonite deposits occur as massive and small-scale ore. The deposits are located around fault lines in the area. Threrefore, it seems tat the genesis of the bentonite deposits are closely related to the faults. Mineralogical characteristics of montmorillnite and associated minerals in the ventonites are simillar in all deposits. In some bentonite mines, it is observed that the thick andesite bodies occurred in the most upper part of the mines have been altered partially to bentonite. Judging from the occurrences and mineralogy, it is obvious tat the bentonite diposits were not formed by only a simple diagenetic process. Therefore, it is assumed that the deposits were mainly formed from the alteration by hydrothermal solution or ground water moved along the structually weak zone such as fault.

영남지방 벼-보리 이모작답에서 가장 널리 시행되고 있는 보릿짚 처리방법인 소각이 대기환경에 미치는 영향을 소각시 발생하는 온난화가스, 대기오염가스 및 분진발생량을 중심으로 살펴보았다. 보릿짚 소각시 온난화가스 발생량은 CO₂376.8, CH₄ 1.56, N₂O 0.05 kg/10a 로서 CO₂의 발생량이 가장 많았으며, 대기 오염가스 중에는 유기물의 불완전 연소시 배출되는 CO발생량이 28.8 kg/10a로서 가장 많았다. 그 외 SO₂ H₂S, NH₃, NO등의 질소 및 황 함유 유해가스도 소량 발생되었고 발생된 PM 10 분진의 대부분은 인체에 미치는 영향이 PM 10보다 큰 PM 2.5로 이루어져 있었다. 또한 수확시기가 빠르거나 수분함량이 높은 보릿짚일수록 온난화가스 및 대기오염 가스의 발생량이 증가하고 소각 연기내 PM 10 분진중 PM 2.5의 미세분진 비중이 높았다. 수확적기로 알려진 출수 40일 이후의 보릿짚은 출수 후 40일된 보릿짚 소각시 발생하는 대기오염가스 발생량과 큰 차이가 없었다. This study was carried out to determine impacts of burning of barley straw produced from rice-barley double cropping paddy field on air quality by investigating emissions of greenhouse gases (CO₂, CH₄ and N₂O), air pollution gases (CO, SO₂, H₂S, NH₃ and NO) and particulate matters (PM 10 and PM 2.5). When the barley straw at a rate of 4.5 t/ha was burned at open status, the emitted GHGs amounts were CO₂ 376.8 kg/10a, CH₄ 1.56 and N₂O 0.06. The amount of CO emission was the largest among air pollution gases. These results showed that the range of 45~55% of total C in barley straw was emitted as CO₂-C, followed by CO-C (6.4~5.9%) and CH₄-C (0.5~0.7%). As far as moisture content in barley straw is concerned, the higher moisture content that the barley straw contains, the larger amount of air pollution gases and the higher portion of PM 2.5 in PM 10 were emitted when it burned. In case of harvesting time of barley straw, emission amounts of greenhouse, air pollution gases and PM 2.5 portion in PM 10 had tendency to increase when earlier harvested barley straw was burned.

In the Donghae bentonite mine area, the alteration minerals such as smectite, clinoptiloite, mordenite, opal CT and feldspar occur in the tertiary tuffaceous rocks. The mineral assemblages of the rocks are grouped into four types : volcanic glass-smectite, clinoptilolite-smecite-opal CT, mordenite-potassium feldspar-smectite, well-crystalline smectite-potassium feldspar. The first two assemblages are found in the bedded tuffaceous sedimentary rocks. The other types are distributed in the rhyolitic rocks of eastern part of this area. Mineralogical properties of the smectites in the each assemblage type were investigated by X-ray diffraction, chemical analysis, DTA and IR. The results show that the all smectite specimens are mainly composed of (Mg, Ca)-montmorillonite. But the well-crystalline smectites show the considerably different data from other smectites in mineralogical properties. Judging from the occurrence and properties, it seems that the well crystalline smerctite can not interpret to be formed only by diagenetic alteration. Perhaps it can be considered that the formation of the smectite was influenced significantly significantly by hydrothermal alteration.

The aims of this study are to demonstrate the reliability and the validity of the Korean version of Behavioral Dyscontrol Scale (BDS-K.) and to present the normative values of BDS-K among the Korean elderly. The BDS-K was administered in a standardized manner to 1,389 healthy volunteers aged over 65 years recruited from the cornmunity. The elderly with serious neurological, medical or psychiatric disorders were excluded using screening tests. BDS-K showed good intemal consistency (Cronbach's alpha=0.812), test-retest reliability (r=0.88) and inter-rater reliability (r=0.99). Age and educational level were found to affect BDS-K score. Based on this result, normative values of BDS-K. were calculated by age and educational level. The validity of the BDS-K were demonstrated in comparison with MMSE-KC (r=0.72). BDS-K is reliable and valid instrument for measuring executive function of the elderly. The normative values suggested by this study can be widely used as reference values to objectively interpret BDS-K scores of the Korean elderly.

Objectives : Pneumoconisis and noise-induced hearing loss (NIHL) have been reported as main occupational diseases by the Special Health Examination. The Industrial Accident Compensation Insurance has reported various work-related diseases, however, these two diseases occupied almost a half of compensated cases. Therefore, it was not well known about the status of occupational diseases other than pneumoconiosis, NIHL, and cardio-cerebrovascular accident (CVA). This study was conducted to analyze claimed cases as an occupational disease, that was requested to the Korea Industrial Safety and Health Agency (KOSHA). Methods : The local office of the Korea Labor Welfare Corporation (KLWC) has asked the KOSHA for confirmation of claimed cases as an occupational disease. We analyzed 379 cases requested from KLWC, the Ministry of Labor, employers, unions and occupational health agencies from 1992 to 1999. Results : Male was 80.7 % of the requested cases. Their mean age was 42 years old and 75.5 % of them were more than 35 years old. The requested cases were increased rapidly from 25 cases in 1992 to 108 cases in 1999 and the accept rate was 50.7 %. The majority of requested cases were respiratory diseases(22.4%), cancers(18.5%), Neuropsychiatric problems(14.5%), and musculoskeletal problems(13.5%). The accept rate was high in reproductive, respiratory, musculoskeletal and digestive disorders and low in neuropsychiatric, renal and otologic problems and occupational cancers. 73.6% of them were caused by chemical agents, especially 28.5 % were by organic solvents. 67% of them were clinically confirmed at university hospitals. A half of the cases were from KyongIn area, even the request came from the whole country. Conclusions : A claim was common in workers whose age was over 35 years old and exposure history was over 10 years. The respiratory diseases and neuropsychiatric disorders were still main problems in occupational health and occupational cancers was increasing even though its accept rate was not high yet.

The smectite-rich clays were found locally in Paleozoic calcareous sedimentary rocks in the Samcheok area. Their occurrences were investigated in detail, and the physico-chemical properties of the clays were also determined by X-ray diffraction, chemical analysis, thermal analysis and cation exchanging experiment. The smectitie clays occur as the fissure filling dyke developed in calcareous semimentary rock and as alteration products of instrusive rhyolite. Most of clays occur at the contact between the sedimentary rock and the rhyolite, and the alteration zone was observed only in rhyolite body close to the contact. Judging from their occurrences, it is believed that the smectite-rich clays in this area were formed by the hydrothemal alteration. The smectite clays from the area are mainly composed of Ca-montmorillinite, and associated with small quantities of quartz, opal-CT and feldspar. The montmorillinites from this area lower in Fe content, and higher in exchangeable Ca ion, compared to those of bentonite from the Yangnam-Yeongil area.

The purpose of the present study was to investigate the participation patterns of middle aged subjects, and to make suggestions for the promotion of the sport-for-all movement in Korea. The results of a questionnaire answered by 2125 middle aged male and female subjects were compared between sexes, age groups and educational back-ground using SAS computer program. The conclusions of this study were as follow: 1. Most subjects answered that they had very limited leisure time during week days and week ends. 2. It was shown that most middle aged subjects preferred to rest instead of participate in sport activities during their leisure time. 3. The intensity and frequency of sport activity were too low to improve cardio-vascular endurance. 4. To improved the availability of sport facilities, better management was recommanded.
