For comparison of mycelial colonization of Phellinus linteus on logs, several techniques of inoculation were tested; sterilized short log inoculation, drilling inoculation and log-end sandwich inoculation. The mycelial colonization of P. linteus on logs was good in the treatment of sterilized short log inoculation, but poor in the traditional methods such as drilling inoculation and log-end sandwich inoculation. The initial mycelial growth and the full mycelial colonization of P. linteus in logs were the best in case of 20 cm logs under the condition of 42% moisture content. Also, the initial mycelial growth of P. linteus was accelerated over 12 hours of sterilization. Burying method of logs after $5{\sim}6$ months of incubation was the best for formation of basidiocarps of P. linteus. The formation of fruiting body of P. linteus was quite good in the cultivation house at $31{\sim}35^{\circ}C$ and over 96% of relative humidity.

The purpose of this paper is to scrutinize how Parks recalling, deconstructing and reconstructing African-American memories of the absences in American history through a black Lincoln impersonator named, The Foundling Father or The Lesser Known. Parks unearths and reconstitutes a significance for the historical event of Lincoln's assassination by repetitive mimicry and verbal puns. As a pun of the Founding Father, the Foundling Father reminds us of Abraham Lincoln, one of the most venerated figures in American history. In the first act, the black Foundling Father performs as The Great Man. This inverted minstrel show of the black Foundling Father performing a white Lincoln exposes the desire of the Foundling Father to insert his narrative within the history of America. With a series of assassinations, the African-American performers figuratively murder the power and control of the American myth. In the second act, his wife Lucy and his son Brazil dig relics from the past out of 'The great hole of history' instead of the Foundling Father. Digging and burial for African-Americans are their livelihood and their calling as well. As Parks pointed out, they should locate the ancestral buried ground, dig for bones and find bones because so much of African-American history has been unrecorded, dismembered and washed out. Parks leaves the possibilities of digging and burying on the black history through Lucy and Brazil.

Purpose: Global shortages in nursing and strong demand for nursing services provided Korean nurses with more overseas employment opportunities, especially in the developed countries such as the United States and Canada. The purpose of this study was to explore the ageing experiences of the Korean nurses dispatched to Germany in the 1960s and 1970s. Methods: The researcher interviewed 10 Korean nurses living in four cities in Germany. Interviews were performed twice in January and July, 2010, and the data, in the form of field notes and interview transcripts, were analyzed using the Agar's (1980) ethnographic method. Results: The ageing experiences of the participants can be summarized into three theme stages: coming upon old age, reluctantly realizing getting old, and finally accepting being old. The first stage is characterized by 'wiring money to homeland all throughout youth', second 'still feeling like a stranger anywhere', and finally 'burying homeland in heart'. Conclusion: The research findings not only suggest crucial materials for training prospective nurses overseas for their successful settlement, but also shed lights on related problems and solutions with ageing experience in overseas employment.

Piezo-ceramics are special materials which transform energy between mechanical and electrical forms. Bender-elements are composite materials consisting of thin piezo-ceramics and elastic shims, and are widely used as actuators and transducers in the field of electronics, robotics, autos and mechatronics utilizing the effectiveness of energy transformation capability. In geotechnical engineering, commercial bender-elements are used in laboratory as source and receiver in the measurements of soil stiffness. The elements were built by using various metal shims sandwiched between piezo-ceramics and coating over the composite in the research. A pair of elements were buried in a concrete block and used as source and receiver to measure the stiffness of the concrete. The test results were verified by comparing with the resonant column testing results. In a preliminary stage of the development of an in-situ seismic testing equipment using bender-elements for soft clay materials, shear waves were generated and measured by burying the elements in the barrel of kaolinite and water mixture. The measured shear wave signals were so distinct for the first-arrival pick that applicability of the elements in the field measurements is very promising.

As part of the government's fishery resource creation policy, fishing ground creation projects have been undertaken in Korea's major seashore fishing spots since the 1970s, where artificial reefs constructed using new materials that make up for the weakness of concrete reefs have been used. In this study, the stability of these artificial reefs when acted upon by external forces, their ability to attract and gather fish, and their economic feasibility were examined. For this purpose, an experimental artificial steel reef was constructed and was installed in an area of the sea. Then the corrosion of the experimental material attached to it was investigated. The efficiency of the artificial steel reef was then verified by examining its functionality, removal, and burying, as well as the speed of insertion of living things into its structure and its ability to attract and gather fish.

This paper describes the overvoltage analysis and reduction methods of insulation joint boxes in underground transmission power cables when direct lightning surge strikes to overhead transmission line. An actual 154kV combined transmission line with underground Power cables was modelled in ATPDraw for simulation. Simulations were performed to analyze the overvoltage between insulation joint boxes, sheath-to-ground voltage according to the distance between cable conductors, cable lengths, burying types, CCPU connection types. The most effective method to reduce the induced overvoltage of Insulation joint boxes was proposed. It is evaluated that the proposed reduction method riven from the detailed simulations can be effectively applied to the actual underground power cable systems.

도시의 급속한 팽창에 따라 지상시설물들이 도시미관, 안정성, 도시교통문제를 야기하므로 점점 지하에 매설되어가고 있지만 그 종류가 다양하고 복잡한 형태로 매설되어 있어 통합체계를 원활히 유지하고 효과적으로 관리하는 것이 매우 중요한 과제가 되었다. 그렇지만 종합관리를 위한 자료의 결여로 지하공간을 무계획적으로 활용뿐만 아니라 지하굴착 공사 등 안전사고를 유발하여 인명 및 재산피해 초래하는 것은 물론 다양한 정보시대에 국가정보가 일시 중단될 때 많은 경제적 손실을 가져오게 되는 것이 현실이다. 이러한 상황에서 지하시설물에 대한 정확한 탐사가 이루어져야만 이에 따른 양호한 도면을 작성할 수 있으므로 여러 가지 지하시설물 탐사기법과 여러 가지 현장조건에 따른 탐사정확도를 비교, 분석한 결과 다음과 같은 지하매설물 탐사 정확도를 구할 수 있었다.

In order to examine the influence of sprue(used to make crown supplements) on casting, 3 kinds of sprue materials(wax, wood, plastic) and 3 types of sprue(round, square, triangle) were made and buried and cast, then the comparison and analysis of casting characters among sprue materials and among sprue type show the following results : 1. The comparison of casting characters in accordance with sprue materials shows wax sprue of 83.3%, wood sprue 81.3%, and plastic sprue of 80.7%, Wax sprue was the bast materials for casting, However there was no statistically significant difference of casting characters among was, plastic and wood. 2. The comparison of casting in accordance with sprue types shows square sprue of 94.0%, round sprue of 86.9% and triangle sprue of 84.2%. square sprue had a best casting character. 3. When a ring cast using wood sprue was classified from burying materials. its cutting of casting body and sprue indicated much more than any other sprue material. It seems to be caused by the influence of wood residuals and carbon occurrence.

Over the decades, TNT has been produced indiscriminately to be utilized in many fields owing to its ability to manipulate the explosion. Yet, the proper technique for disposal of TNT and the waste residues had not been developed so that the large amount of TNT waste was being piled up. Upon the agreement to demilitarization of old weapon, a study on the disposal methods for TNT and the waste treatment have been raised for their dangerous nature. Since then, from burying in landfill to utilizing supercritical fluid-based oxidation, a lot of research is actively ongoing, but little progress has been made in Korea compared to developed countries. This review paper covers all the technologies developed for TNT and its waste disposal including the concept, advantage, and disadvantage of those technologies. Also, suggested here are the future research directions.
