The purpose of this study is to search for solutions of the problems of recent Christian Education as such believers decrease, education focused on individuals, and knowledge centered education. Some systemic approaches by Timothy A. Lines etal. were tried, but they were difficult to apply to church education because of their abstraction. Therefore, design systems of education of B. H. Banathy and Peter M. Senge etal. were tried to apply to church education here. As a result, some important contents of systemic Christian Education is to present agreements between the visions of the church and the various needs of constituents of the systems in the purpose of the system, the formations of the systemic Christian Education is to be integrate. Then, they will open the possibility to conquest the poor present surroundings of church education. Especially, relations of the constituents of the systems is to be co-relational and for that, mutual respect and equality spirit is to be presupposed. The systemic Christian Education will be change always, but the appropriation of the systems in the given times will be secured through the directive verification for churches.
Immature Heterotopic Ossification in the Iliacus Muscle in Spinal Cord Injury - A Case Report -

Heterotopic ossification (HO) is a frequent complication associated with spinal cord injury and can lead to significant problems during rehabilitation. Surgical resection of HO could be applied to patients who do not respond to conservative treatment. To reduce the risk of recurrence after the operation, radiation therapy and NSAID or bisphosphonate administration may be utilized. We report the case of a 48-year-old male with a T3-sparing spinal cord injury who underwent successful treatment of immature HO in the iliacus muscle with a combination of surgical resection, radiation therapy, and NSAID administration. 이소성 골화는 척수 손상과 연관되어 발생 할 수 있는 합병증이며, 환자의 재활 치료에 심각한 문제를 야기할 수 있다. 수술적 절제는 보존적 치료에 실패한 경우에 시행한다. 수술 후 재발의 위험성을 줄이기 위해, 방사선 조사, 비스테로이드 소염제 또는 bisphosphonate를 이용한 치료를병행한다. 저자들은 흉추 3번의 불완전 척수 손상이 있는 48세 남자 환자에서 장골근 내에 발생한 미성숙 이소성 골화를 수술적 절제와 방사선 조사 및 비스테로이드 소염제를 병행 치료하여 좋은 결과를 얻었기에 이를 보고하는 바이다.
Effects of Irradiation on PTC Performance of Polyethylene oxide/Carbon Black Blends
박종석,강필현,노영창,서동학 한국공업화학회 2001 한국공업화학회 연구논문 초록집 Vol.2001 No.-
Irradiation can produce crosslinking, mam chain scission, production, and /or removal of unsaturation, etc. Crosslinking leads to a network, an effect that has extensive technological applications, while scission breaks up the molecules and may eventually degrade them. When an irradiation technique is used in polymer PTC(positive temperature coefficient) materials, it can improve the PTC intensity and stabilize PTC functions significantly. In this study, we described the effects of y -rays and electron beam(EB) on the PTC performance of polyethylene oxide (PEO) /carbon black blends with low temperature PTC. PEO with molecular weight of 8,000,000 was selected as the polymer matrix in this work. Carbon black with particle size 86 nm was used. The CB and polymer were mixed in a Brabender Plastograph at 120°C for 15 min. The composition thus produced was sandwiched between a pair of copper foils(0.04 mm thick), which served as electrodes. PEO/CB blends were irradiated in nitrogen with <sup>60</sup>Co r -rays and electron beam accelerator. The absorbed dose ranged from 1-150kGy. The influences of irradiation on PTC performance of the blends were analyzed.
A study on Korean companies’ entry strategies into the Chilean e-commerce market
박종석 한국무역연구원 2011 貿易 硏究 Vol.7 No.4
This study focused on the B2C market of Chile’s e-commerce market as there were limitations to accessing information on the B2B market. Therefore analysis on the B2B market has not been included. Therefore including research on the B2B market will be a way to increase the level of contribution of this study. Although Chile’s e-commerce market does not take up the biggest proportion in the South-Central America region, for companies who wish to enter the South-Central region, the possibility of success in this region can be verified by entering the Chile market. Currently, Chile's e-commerce market is not as active compared to developed countries. However, considering its great growth potential, it can be said that analyzing it will be highly significant. Especially since there is a lack of information on the Chilean e-commerce market, the research results of this paper can provide strategic guidelines to companies that aspire to enter the Chilean market.
