뇌법은 도교의 중요한 법술로서 당송(唐宋)이래 매우 흥했는데, 북송의 임영소 등이 신소파(神霄派)를 개창한 이후에 도교 법문을 대표하는 영역이 되었다. 그로부터 각종의 뇌법이 천하에 성행하였고, 도교에는 새로운 뇌신들이 거듭 나타나게 되었다. 그 대표적인 것이 뇌법신앙의 구진천존(九宸天尊)인데, 이 아홉 천존들은 도교의 최고신인 삼청성조(三清聖祖)의 통치 하에 있는 것으로 간주되었다. 『옥추보경』은 북송 때 탄생하였는데 이 경전이 세상에 널리 발간되어 구천응원뇌성보화천존에 대한 신앙이 형성된 것은 남송 시기 백옥섬(白玉蟾) 이후이다. 『옥추보경』은 구천응원뇌성보화천존의 법문(法門)을 선양하기 위한 방책으로 천존의 성호를 부를 것을 권장한다. 법문을 염송하는 것은 매우 쉽고도 간단하여 누구나 할 수 있었으므로 사회적으로 크게 확대되었다. 특히 『봉신연의』와 『서유기』와 같은 문예소설에 뇌성보화천존이 등장함으로 해서, 민중들은 뇌성보화천존을 더욱 널리 숭배하게 되었다. 현재도 중국의 민간에서 이 신격에 대한 신앙은 매우 보편적이다. 구천응원뇌성보화천존은 옥청진왕(玉清真王)의 화신(化身)이다. 뇌성보화천존은 시방에 그 형체를 나타내고, 중생들을 고뇌로부터 구제하고 이끈다. 36천을 주재할 권능이 있으며, 자비로운 모습으로 모든 겁에 응한다. 또 뇌성보화천존의 주변에는 뇌공(雷公), 우사(雨師), 풍백(風伯)을 비롯한 십대원사(十大元帥)와 등백온원사(鄧伯溫元帥), 신한신원사(辛漢臣元帥) 등의 신장들이 보인다. 이러한 신장들은 양송(兩宋) 시대에 출현하였으며 대다수가 뇌부의 제신들이다. 뇌성보화천존 신앙을 구현하기 위한 재초 의식에는 천지 제신(諸神)이 강림하기를 청하는 뇌정사과(雷霆謝過)와 죄를 뉘우치고 복을 비는 참의(懺儀) 또는 참회문식(懺悔文式) 등이 있다. 이런 법식들은 매우 전문적인 것이고, 일반인들에게는 법문을 염송하는 간편한 방법인 십자천경법(十字天經法)이 널리 퍼졌다. 즉 늘 경건한 마음으로 천존의 성호를 오랫동안 염송하게 되면 공덕원만(功德圓滿)의 경지에 도달할 수 있다는 것이다. 『옥추보경』은 민중의 세계에 깊은 영향을 끼치고 광범위하게 알려져 그 주해나 주석본만도 이십여 종에 이르렀고 송원 이래의 핵심적인 도교 문헌의 하나로 자리매김하였다. 『옥추보경』은 일본과 한국 등지에도 급속히 전파되었다. 한국에는 고려시대에 신소뇌법(神霄雷法)이 전해졌는데, 특히 고려 예종 13년(1118년) 7월에 중국 도교 의학이 고려에 전승되었을 때의 도교 의학이 『옥추보경』을 위주로 한 치료법이었다. 그리고 그 흔적은 조선의 허준이 주편한 『동의보감』에서도 찾아볼 수 있다. 조선의 민간에서는 많은 사람들이 『옥추보경』을 송독하였고 거기에 수록된 부록(符籙)을 운용하였으며 이로써 병을 몰아내고 잡귀를 물리쳐 생명을 지키기를 바랐다. 현대 한국에서는 구천응원뇌성보화천존강성상제에 대한 신앙이 크게 성행하고 있으니, 그 종단이 바로 대순진리회이다. 대순진리회는 증산 성사께서 인세에 강림하시기 전에 구천대원조화주신이며, 화천 후 구천응원뇌성보화천존상제의 위에 임하였다고 신앙한다. 즉 증산이 천존상제의 화신이라 믿는 것이다. 이것과는 좀 다르지만, 인간이 신의 화신이 되는 신성한 변화를 뇌법에서는 '변신(變神)'이라고 부른다. 변신은 내련(內煉)을 행할 때나 시법(施法)시에 도인들이 필히 진입해야 할 특이한 정신 상태로서, 자아의 존재를 망각하고 신진(神真)으로 변화하여 인신합일(人神合一)을 이루는 것을 의미한다. 이러한 변신은 대순진리회의 수도 목적인 도통과도 한편으로는 유사한 면이 있다고 생각된다. 대순진리회가 목적하는 지상신선실현이 의미하는 것은, 사람이 도를 깨닫는 노력을 통해 신의 경지에 도달하는 것이 아니라 인간의 본질과 천성을 회복하여 이에 상응하는 신과 합일하는 것이라는 점에서 뇌법의 변신과 유사한 점이 있다고 할 것이며 이에 대해서는 추후 연구과제로 남겨둔다.

This article reports an agar-degrading marine bacterium and characterizes its agarase. The agar-degrading marine bacterium, KC-1, was isolated from seawater on the shores of Sacheon, in Gyeongnam province, Korea, using Marine Broth 2216 agar medium. To identify the agar-degrading bacterium as Agarivorans sp. KC-1, phylogenetic analysis based on the 16S rRNA gene sequence was used. An extracellular agarase was prepared from a culture medium of Agarivorans sp. KC-1, and used for the characterization of enzyme. The relative activities at 20, 30, 40, 50, 60, and $70^{\circ}C$ were 65, 91, 96, 100, 77, and 35%, respectively. The relative activities at pH 5, 6, 7, and 8 were 93, 100, 87, and 82%, respectively. The extracellular agarase showed maximum activity (254 units/l) at pH 6.0 and $50^{\circ}C$ in 20 mM of Tris-HCl buffer. The agarase activity was maintained at 90% or more until 2 hr exposure at $20^{\circ}C$, $30^{\circ}C$ and $40^{\circ}C$, but it was found that the activity decreased sharply from $60^{\circ}C$. A zymogram analysis showed that Agarivorans sp. KC-1 produced 3 agar-degrading enzymes that had molecular weights of 130, 80, and 69 kDa. A thin layer chromatography analysis suggested that Agarivorans sp. KC-1 produced extracellular ${\beta}$-agarases as it hydrolyzed agarose to produce neoagarooligosaccharides, including neoagarohexaose (21.6%), neoagarotetraose (32.2%), and neoagarobiose (46.2%). These results suggest that Agarivorans sp. KC-1 and its thermotolerant ${\beta}$-agarase would be useful for the production of neoagarooligosaccharides that inhibit bacterial growth and delay starch degradation.

To enhance groundwater quality and soil nutrient management in fertigated plastic film house, groundwater samples from Jinju 52, Sacheon 3, Changnyeong 3, Sancheong 4 and Namhae 2 sites and soil samples from Jinju 23 sites were collected from September to November in 2004. The average concentration of $NO_3-N$ in groundwater was $12.0mg{\ell}^{-1}$ and 20% of survey sites exceeded the limiting level $(20mg{\ell}^{-1})$ of agricultural goundwater quality. The amount of ions in groundwater was in the order of $Ca^{2+}>Na^+>Mg^{2+}>NH_4-N>K^+$ in cations and ${HCO_3}^->{SO_4}^{2-}>NO_3-N>Cl^-$ in anions. Electrical conductivity of groundwater was positively correlated with $Ca^{2+},\;Cl^-,\;Mg^{2+},\;{SO_4}^{2-},\;NO_3-N\;and\;Na^+$ concentrations. In addition, it had significantly positive correlation with sum cations and anions, respectively $({\Sigma}cations\;(me{\ell}^{-1})$ = EC values $(dS\;m^{-1}){\times}4.65,\;{\Sigma}anions\;(me{\ell}^{-1})$ = EC values $(dS\;m^{-1}){\times}7.63\;and\;{\Sigma}\;(cations+anions,\;me{\ell}^{-1})$ = EC values $(dS\;m^{-1}){\times}11.1)$. The proportions of soil chemical properties over the critical levels for crop production in fertigated plastic film house were 56.5% in pH, 47.8% in OM, 95.7% in available $P_2O_5$, 78.3% in exchangeable K, 87% in exchangeable Ca, 56.5% in exchangeable Mg and 43.5% in EC. Soil pH was positively correlated with pH $(r=0.540^{**})$ and ${HCO_3}^-$ concentration $(r=0.523^{**})$ of groundwater.

To study the pattern of prenatal care utilization and its determinants in rural Korea, 976 mothers (65.5%) out of 1,489 living mothers in Chinyang, Sachon and Hapchon Counties in Kyongsangnam Province who had delivered a baby between July 1, 1990 and June 30, 1991 were interviewed by the Myon health workers from January 3 through February 15, 1992. The Anderson's behavioral model for health service utilization was applied to develop the frames for analysis. The dependent variable was a number of prenatal care visits. And the independent variables included In the model were the variables pertaining to the predisposing, enabling, medical need and other components. The proportion of mother who had ever received the prenatal care service for the index pregnancy was 97.3%. However, the proportion of mothers who had made more than 10 visits was only 20.6%, which indicated that majority of mothers had paid far less visits than recommended $10{\sim}12$ visits for each normal pregnancy. The low utilization of prenatal care services (none or less than 4 visits) was related to mother's low educational level, the high birth order, beneficiary of the medical aid, the absence of clinic in the community, no diagnosed disease of mother during pregnancy, and mothers engaged in farming. Inequity of access seemed to exist because social structure variables and the variables of enabling component were important predictors. And there seemed to be high mutability in equalizing the distribution of prenatal care services because the variables of enabling component such as type of medical security and whether there was a clinic or not in the community were substantially important.

The site categorization and corresponding site amplification factors in the current Korean seismic design guideline are based on provisions for the western United States (US), although the site effects resulting in the amplification of earthquake ground motions are directly dependent on the regional and local site characteristic conditions. In these seismic codes, two amplification factors called site coefficients, $F_a$ and $F_v$, for the short-period band and midperiod band, respectively, are listed according to a criterion, mean shear wave velocity ($V_S$) to a depth of 30 m, into five classes composed of A to E. To suggest a site classification system reflecting Korean site conditions, in this study, systematic site characterization was carried out at four regional areas, Gyeongju, Hongsung, Haemi and Sacheon, to obtain the $V_S$ profiles from surface to bedrock in field and the non-linear soil properties in laboratory. The soil deposits in Korea, which were shallower and stiffer than those in the western US, were examined, and thus the site period in Korea was distributed in the low and narrow band comparing with those in western US. Based on the geotechnical characteristic properties obtained in the field and laboratory, various site-specific seismic response analyses were conducted for total 75 sites by adopting both equivalent-linear and non-linear methods. The analysis results showed that the site coefficients specified in the current Korean provision underestimate the ground motion in the short-period range and overestimate in the mid-period range. These differences can be explained by the differences in the local site characteristics including the depth to bedrock between Korea and western US. Based on the analysis results in this study and the prior research results for the Korean peninsula, new site classification system was developed by introducing the site period as representative criterion and the mean $V_S$ to a depth of shallower than 30 m as additional criterion, to reliably determine the ground motions and the corresponding design spectra taking into account the regional site characteristics in Korea.

Such stream characteristics as the numbers, lengths, orders of stream channels, and drainage density are the essential elements for the analysis of drainages in planning of watershed management in a drainage basin. The drainage net is the pattern of tributaries and master streams in a drainage basin as declineated on a planimetric map. Stream order is a measure of the position of a stream in the hierarchy of tributaries. Density of the drainage is given by the quotient of the cumulative length of stream and the total drainage area. Drainage density then is simply a length per unit of area. In this study, the Anyang-cheon upper-watershed is selected for the survey and analysis of the stream system and drainage density in view point of the useful collection of data for effective watershed management planning. The Anyang-cheon upper-watershed is consisted of about 12,600 hectars of drainage area including the 13 Sub-stream. Total length of the Stream (as described in the Stream Law) in the survey area is measured as much as 71.2km, and that of the Small-stream as descrived in the Saemaul Stream Survey Book (1972) is calculated as 43,010 meters. Besides of this lengths, measured about 43,410 meters of the Small-stream and about 71,900 meters of the Torrential valley through this study. The range of the drainage density among the 13 Sub-streams having sub-watershed is analysed as from 14.79 to 24.10, and average value of drainage density in the entire watershed is calculated as 18.21 in case of including the length of the Torrential valley and 12.50 in case of excluding the same. It is required that the standard classification system in classifing for the characteristics of identification among the Stream, Sub-stream, Small-stream, Torrent, and Torrential valley must be satisfied through joint study of the authorities concerned.

This study is designed to find out the determinants of dual-earner wives' needs for family-supportive services. For this purpose, a hypothetical model which explains the relationships among 6 stressors, role overload, stress and needs for 4 family-supportive services is developed. Using the data collected by purposive sampling from 234 professional women and 208 blue-collar women living in Chinju and Sacheon, the hypothetical model developed in this study was tested. In order to examine occupational class differences, a model for professionals and another model for blue-collars were developed separately and compared. For data analysis, a covariance structure analysis was used. The best-fitting model for professional women (df=141, GFI=0.928, CFI=0.965) and the model for blue collar women (df=141, GFI=0.902, CFI=0.912) were found. As a result of comparing two models, 9 common relationships were found:l)Greater dissatisfaction with child care service increases role overload; 2)Longer work hours increases role overload; 3) Higher level of role overload increases stress; 4)Higher level of stress increase needs for leaves; 5)Older child increases needs for flexible work pattern; 6)Younger child increases needs for finalcial assistance for child care fee; 7)needs for financial assistance for child care increases needs for on-site child care services; 8)needs for on-site child care services increases needs for leaves; 9)needs for leaves increases needs for flexible work pattern. With the exception of these 9 common relationships, the analyses revealed substantial differences between professional and blue-collar dual-earner wives. Based on the common and differential needs between 2 groups of wives, the effective ways to provide family-supportive services according to the needs of individual dual-earner wives who are in different familial, financial, and work conditions were suggested.
