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 paper analyzes the characteristics of population change and makes the population projection in the mountainous area of Korea. Mountainous areas are defined as local towns (eup or myeon) with forest area more than 70 percent of land area, population density less than 111 people per square kilometer, and plowland area less than 21 percent of land area. The population in mountainous areas has decreased dramatically, while the ageing index has increased over the past two decades. To make the population projection, the cohort-change ratios method is applied. The results revealed that a multitude of young people aged 10 to 39 moved to cities to find education and job chance and some people aged 40 and over moved to mountainous areas as the trends of urban-to-rural migration. This continuing trend will culminate in 680 thousand people in population and 1,035 of ageing index in 2030, which will lead to the unequal land development and inefficient forest management. Thus, policy makers need to develop stimulus plans to revitalize and stabilize the economy of mountainous areas.

The purpose of this paper is to estimate technical efficiency, scale efficiency, and environmental efficiency by income level of Korean farms, and analyze the factors to decide three efficiencies. Depending on the non-parametric methods, we estimate technical using inputs and outputs of total farms without assuming of goods or behavior of optimization. The average technical efficiency of total firms under constant return to scale and strong disposability is 0.437. The technical inefficiency was caused by 47.7% in pure technical inefficiency, 11.3% in scale failure, and 3.2% in environmental inefficiency. The number of firms under increasing return to scale occupied almost 70% and 27% of total firms respectively. Higher are income class, middle debt & long debt per asset, and N effluents per cultural land, higher technical efficiency. The increases of BOD discharges per cultural land and machines per cultural land deteriorate environmental efficiency.

This study tried to propose a smart farm technology strategy suitable for the domestic situation, focusing on the differentiation suitable for the domestic situation of ICT technology. In the case of advanced countries in the overseas agricultural industry, it was confirmed that they focused on the development of a specific stage that reflected the geographical characteristics of each country, the characteristics of the agricultural industry, and the characteristics of the people's demand. Confirmed that no enemy development is being performed. Therefore, in response to problems such as a rapid decrease in the domestic rural population, aging population, loss of agricultural price competitiveness, increase in fallow land, and decrease in use rate of arable land, this study aims to develop smart farm ICT technology in the future to create quality agricultural products and have price competitiveness. It was suggested that the smart farm should be promoted by paying attention to the excellent performance, ease of use due to the aging of the labor force, and economic feasibility suitable for a small business scale. First, in terms of economic feasibility, the ICT technology is configured by selecting only the functions necessary for the small farm household (primary) business environment, and the smooth communication system with these is applied to the ICT technology to gradually update the functions required by the actual farmhouse. suggested that it may contribute to the reduction. Second, in terms of performance, it is suggested that the operation accuracy can be increased if attention is paid to improving the communication function of ICT, such as adjusting the difficulty of big data suitable for the aging population in Korea, using a language suitable for them, and setting an algorithm that reflects their prediction tendencies. Third, the level of ease of use. Smart farms based on ICT technology for the development of the Industry6.0 (1.0(Agriculture, Forestry) + 2.0(Agricultural and Water & Water Processing) + 3.0 (Service, Rural Experience, SCM)) perform operations according to specific commands, finally suggested that ease of use can be promoted by presetting and standardizing devices based on big data configuration customized for each regional environment.

Collated data from the 1995-1996 field surveys of weed seeds buried in the plough layer of peat soil in Selangor district were analysed to assess species-dominance and spatial pattern of distribution of weed seeds based on selected quantitative indices and index of dispersion. Forty five species within 14 families were recorded of which 24 were broadleaves, 12 grasses and 9 sedges. They comprised ca. 53.2, 31.2 and 15.6%, respectively based on total population counts. Total seed population was ca. $8.14{\times}10^7$ seeds/ha within the fast 25cm soil depth. Wide variabilities in population counts were registered among species ranging from < $7.0{\times}10^4$ seeds/ha for Amaranthus gracilis to ca. $5.64{\times}10^6$ seeds/ha for Heteropogon contortus. Seeds of Cleome rutidesperma was the most abundant(ca. $2.347{\times}10^7$ seeds/ha). Difference in seed population counts may be attributed to inherent variation in fecundity, population fluxes, their spatial distribution patterns and the agronomic practices prevailing in the areas of survey. The profile distribution of soil seed banks was skewed within the first 0 - 10cm depth, comprising ca. 69% of the total seed counts. Seed counts in the 10 - 15, 15 - 20 and 20 - 25cm soil profiles were in the order of 17.9, 8.6 and 4.0% of the total populations, respectively. Weed seeds of all species displayed different degree of aggregated pattern of distribution with variance-to-mean ratios of > 1 and Lloyd's mean crowding($m^*$) values from 1.244 for Cyperus iria, Phyllanthus debilis, Phyllanthus urinaria, Scirpus grosses and urinaria lagopodiodes to 9607.7 for Cleome rutidosperma. Lloyd's patch indices(Ip) ranging from 5.1 for Aeschynomene indica to 188.5 for Bracharia reptans were registered. Differences in the VMR, $m^*$ and Ip values among species suggested inter-alia inherent variabilities in their disposal capacity from seed source and different agronomic practices prevailing in the areas surveyed.

General procedures of seed preparation as conventional guide had been established in China before most of Korean literature documented them. ‘Chwijongbeob’ (method of seed select) was to select good quality of seeds and to discard the rest. In ‘Seonjongbeob’ (method of seed grading) although China employed only ‘Sooseonbeob’ (method of seed select with water), but seeds were selected in order of selection of seeds by winds, selection of seeds by sieve and selection of seed with water in Korea. As compared with the recent techniques, those methods were perfect techniques for selection of good quality seeds of rice, except for method of seed selection by salt water was developed. The method for measurement of seed moisture, and for measurement of melted snow, spoiled urine and extracted juice by boiling water with the bone of livestock were originated from ancient China. The farming books in Korea were more or less followed the above methods. However, these techniques were complicated and impractical interms of validity and rationality. Also, it is judged that these tchniques are more appropriate in dry areas and alkaline soil of China rather than in Korean conditions. The plowing is a work to begin farming, and is operated for air ventilation between atmosphere and earth. Also, this techniques was adopted in the farming books from the early to the late Chosun dynasty without changes. Fields were deep-plowed in the first, in fall (or in spring) and for cultivation, and were shallow -plowed in the second, in spring (or in summer) and in intertillage. The former was for water reserve and land preparation, and the later was for weed control with intertillage. However, plowing in fall which was different from fallowing in dry areas, was recommended in Korea (Jikseol). but was not practiced in Sejongsilrok. This was changed with time, and plowing for cultivation in Korea was interrelated with use of green manure crops, method of plowing of upseting plough, method of manure practice and sometimes dry plowing. In addition, until the 15th century method of using a kind of plowing-tool made of log as farm tools was created to support reclamation for enlargement of farm land in mountaineous and coastal areas. For desolate farm lands by many internal and external disturbances, one tried to recover yield ability by increasing labor productivity from the 17th or 18th century. To do this, ‘Banjongbeob’ (culture method by upset plowing weed control) and ‘Hwanubeob’(culture method by firing weed control) which were cultural methods of ancient China were readapoted but the results were not clearly informed. Also, the reality of those was reexamined in the end of the Chosun dynasty.

The paper examined whether the fine arts education needed concept of 'Yu' that was suggested by, 'Soyoyu' of Jangja, a representative philosopher of Doka. At first, the paper defined concept of 'Yu' of Jangja as well as background and needs of the fine arts education, and investigated values of 'Yu' of the Oriental painting in aesthetic way to examine whether today's Yu concept can be applied to modern Oriental fine arts education to express. Chapter 2 examined concept and thought of 'strolling (Yu)', and Chapter 3 did background and needs of the fine arts education. Chapter 4 examined an access to practical technique education of the Oriental painting through 'strolling (Yu)': At first, the chapter investigated 'Heosil' of space concept that was researched at Chapter 2, 'Pilmuk' of expression technique, and 'Saeui' of state of spiritual canvas of painters. The findings were as follow: Firstly, when relation between Yu and Oriental paintings was investigated based on formative idea, 'Heo' reminded appreciators of association of ideas, hint and imagination, etc by, 'Sil' that other objects disclosed intrinsic attributes so that it indicated border of positive forgetfulness expressed by artists to have same border between 'Heo' and 'Yu'. Therefore, both 'Heo' and 'Sil' could build up expression as well as appreciation ability by experiencing formative idea to develop creativity and to build emotion and to cognize needs of the fine arts education. Secondly, the artistic state of 'Shin', 'Ki (Simjae)', 'Jeonshin' and, Saeui', etc could be expressed with strength and weakness of both Yin and Yang of Pilmuk. Therefore, the Pilmuk were linked even with creation of both Hyeongsa and artistic form of Saeui. Therefore, freedom at border of spiritual 'strolling' could produce creative power being expressed by thinking, natural appreciation ability, and education that could judge values of aesthetic culture. Therefore, cultivation of aesthetic eye, development of creativity, build up of formative ability and education of human nature, etc could keep identity of the Oriental fine arts education at various modern fine arts.
