연행이론의 관점에서 본 평생학습축제의 현상학

박지연,박신영,이병준 한국문화교육학회 2012 문화예술교육연구 Vol.7 No.1

현재 전국적으로 중앙정부로부터 선정된 평생학습도시들은 매년 평생학습축제를 개최하고 있다. 평생학습축제는 평생학습이라는 같은 주제로 지역별로 개최되는 평생교육 관련 기관·단체 간의 교류를 통한 평생학습문화 진흥과 평생학습사회 실현을 목적으로 하는 학습, 문화, 스포츠, 복지 등의 복합적인 종합축제이다. 지역차원에서는 평생학습축제의 기획과 준비에 비교적 많은 시간과 예산, 노력이 투입되고 있으며 평생교육실천가들의 많은 에너지가 수반됨에도 불구하고 이에 대한 성찰적 연구는 매우 적은 편이다. 본 연구는 평생학습문화의 촉진을 위한 정책적 차원에서 매년 개최되고 있는 지역 평생학습축제의 문제를 다룬다. 학습문화를 촉진하기 위한 목적으로 기획되는 축제가 교육적으로 유의미하기 위해서는 축제에 기저를 둔 연행과 의례에 기반한 새로운 경험과 학습의 이행과정을 이해해야 한다. 기존의 축제들은 정책홍보적 성격을 띄고 있어 축제 주제와 컨텐츠의 탈지역성, 운영의 행정주도성으로 인해 교육적 의미가 내포되지 못한 채 중요한 지역행사로 자리잡게 되는 상황에 이르렀다. 이러한 문제의 발단은 평생학습을 생각하며 축제를 기획하는 사람들이 축제가 가지는 연행이론적 측면에서의 교육적 유의미함을 이론적으로 파악하고 있지 못하는데서 비롯된다. 즐거움과 문화적 분위기속에서 경험과 학습이 촉진될 수 있다는 컨셉이 있다면 지역평생학습축제가 전국적으로 대동소이한 주제와 방식으로 그리고 동원된 특정 계층의 참여자를 기반하지는 않을 것이다. At present, the worldwide lifelong learning cities selected by central government hold lifelong learning festival every year. The lifelong learning festival is a general festival combined by studying, culture, sports, welfare, etc. with the purposes that promotion of lifelong learning culture and realization of lifelong learning society through the exchange among the institutions·organizations related to lifelong learning, held in each region, under the same subject, lifelong learning. At regional level, relatively lots of time, budgets and efforts are invested to planning and preparation of lifelong learning festival and lifelong learning doers put lots of energy to it. In spite of it, there is few introspective studies on it. This study treats problems of regional lifelong learning festival held every year at political level for promoting lifelong learning culture. The process of new experience and studying based on festival's performance and rite must be understood so that the festival which is planned to promote studying culture can be significant educationally. Existing festivals have political publicity characteristics, so they become important regional festivals without educational meaning because of the delocality of festival subject and contents and administrative leading of operation. The problem is caused by that people who plan the festival by considering lifelong learning don't grasp the festival has educational significance theoretically from the aspect of performance theory. If there is a concept that experiences and studying can be promoted in the atmosphere of pleasure and culture, regional lifelong learning festival will be neither progressed under similar subject and method nationally nor participated by mobilized special-class participants.

From the above result, the feeding of chinese root was effective on the improvment of the lipid composition in liver.

Brief Review of Silicon Solar Cells

이준신,Yi, Jun-Sin The Korean Vacuum Society 2007 Applied Science and Convergence Technology Vol.16 No.3

태양광발전이란 태양에너지를 직접 전기 에너지로 변환시키는 것이다. 지난 5년 동안 태양광발전은 세계적으로 높은 성장률을 보여 왔다. 특히 2006년에는 30%, 이상의 성장을 가져왔으며 앞으로 20년 동안 평균 생산 성장률은 매년 27%-34%가 될 것으로 예상하고 있다. 현재까지는 태양광발전을 이용해 생산된 전력의 가격은 기존 전력발전의 가격보다 높지만 태양광 기술의 발전과 효율의 향상으로 점점 그 가격이 떨어지고 있다. 뿐만 아니라 태양전지용의 실리콘 기판의 대량생산은 점점 더 태양전지의 가격 저하를 가져오고 있다. 태양전지의 변화효율의 한계는 30%이다. 현재에는 결정질 실리콘 태양전지가 주를 이루고 있지만 미래에는 박막 실리콘 태양전지가 주도를 이룰 것이다. 2030년에는 박막 태양전지가 90%이상을 이루고 결정질 태양전지는 10% 이하로 떨어질 것을 예상하고 있다. 성균관대학교에서는 결정질 실리콘 태양전지의 저가화와 고효율화를 주 연구로 수행하고 있다. 현재 성균관대학교에서는 스크린 프린트를 이용해서 16% 이상의 다결정 실리콘 태양전지와 17% 이상의 단결정 실리콘 태양전지를 성공적으로 제작하였다. 제 1세대에서 다음 세대의 태양전지 발전의 과정은 새로운 접근법으로 확대되지만 여전히 실리콘이 지금까지 주된 재료로 쓰이고 있다. 2010년까지 이러한 기술들에 대한 격차는 여전히 있지만 태양광발전을 통한 전력생산의 가격은 60 cent/watt 정도로 예상하고 있다. 태양광발전은 청정에너지로서 재생불가능 하고 고갈되어가고 환경오염을 일으키는 다른 에너지와 비교하여 점점 대체에너지로서의 자리를 확립해 가고 있다. Photovoltaic (PV) technology permits the transformation of solar light directly into electricity. For the last five years, the photovoltaic sector has experienced one of the highest growth rates worldwide (over 30% in 2006) and for the next 20 years, the average production growth rate is estimated to be between 27% and 34% annually. Currently the cost of electricity produced using photovoltaic technology is above that for traditional energy sources, but this is expected to fall with technological progress and more efficient production processes. A large scale production of solar grade silicon material of high purity could supply the world demand at a reasonably lower cost. A shift from crystalline silicon to thin film is expected in the future. The technical limit for the conversion efficiency is about 30%. It is assumed that in 2030 thin films will have a major market share (90%) and the share of crystalline cells will have decreased to 10%. Our research at Sungkyunkwan University of South Korea is confined to crystalline silicon solar cell technology. We aim to develop a technology for low cost production of high efficiency silicon solar cell. We have successfully fabricated silicon solar cells of efficiency more than 16% starting with multicrystalline wafers and that of efficiency more than 17% on single crystalline wafers with screen printing metallization. The process of transformation from the first generation to second generation solar cell should be geared up with the entry of new approaches but still silicon seems to remain as the major material for solar cells for many years to come. Local barriers to the implementation of this technology may also keep continuing up to year 2010 and by that time the cost of the solar cell generated power is expected to be 60 cent per watt. Photovoltaic source could establish itself as a clean and sustainable energy alternate to the ever depleting and polluting non-renewable energy resource.

한,중 소비자의 소셜커머스 이용 불평행동 및 재구매의도에 관한 연구

주혁균 ( Yi Jun Zhou ),류미현 ( Mi Hyun Ryu ),이승신 ( Seung Sin Lee ) 한국소비자학회 2012 소비자학연구 Vol.23 No.2

최근 한국과 중국의 소셜커머스 시장은 급속도로 확산되고 있으므로 이에 따른 다양한 유형의 소비자문제들이 발 생하면서 소비자들의 불만이 급증하고 있다. 따라서 본 연구에서는 한국, 중국소비자를 대상으로 소셜커머스 이용시 가장 불만족한 유형을 비교하고, 불만 경험 시 불평행동의 유형별 정도를 파악해보고자 한다. 또한 한국, 중국소비 자들이 각각 소셜커머스를 이용하여 재구매의 의도가 어느 정도 있는지와 재구매의도에 영향을 미치는 요인들이 무 엇인지 비교하여 살펴보고자 한다. 본 연구의 궁극적인 목적은 한국과 중국의 소셜커머스 이용에 있어 소비자 측에서는 양국 소비자들의 불만을 최 소화하고, 만일 소비자들이 불만족이 있다면 적극적인 불평행동을 유도할 수 있는 소비자교육의 기초 자료를 제공 할 것이며, 소비자들의 무분별한 재구매를 감소시키고 정확한 판단 아래 재구매행동이 이루어질 수 있도록 하며, 아 울러 기업 측에서는 소비자들의 불만족 및 불평행동을 파악하여 고객만족 및 재구매의도를 향상시킬 수 있으며, 특 히 중국 진출 기업에게는 유용한 정보제공을 할 수 있을 것이다. 연구결과, 첫째, 소셜커머스 소비자불만족은 한국보다 중국소비자들이 더 높은 것으로 나타났고 하위영역인 사전 기대불일치불만, 모바일 및 결제서비스불만, 사후서비스불만의 세 영역 모두 중국소비자의 불만이 더 높게 나타났 다. 둘째, 한·중 소비자의 소셜커머스 소비자불평행동은 한국보다 중국 소비자들이 사적, 공적불평행동 모두 더 많 이 하는 것으로 나타났다. 중국 소비자가 한국 소비자보다 소비자불만족과 소비자불평행동이 높은 것은 아직까지 중국에서 소셜커머스에 대한 구체적인 정책이나 법률의 부재로 인한 결과라 생각된다. 셋째, 한·중 소비자의 소셜 커머스 재구매의도에는 통계적으로는 유의한 결과가 없었지만 전체적으로 볼 때 중국소비자가 한국소비자에 비해 소셜커머스 재구매의도가 높은 것으로 나타났다. 넷째, 한국, 중국소비자 모두 구매횟수가 많을수록 재구매의도가 높게 나타난 결과를 볼 때 소셜커머스 이용 관련 소비자교육시에는 소비자들의 의사결정과 관련되어 제품 구매시 습관적인 구매가 이루어지지 않도록 구매 의사결정관련 소비자교육이 이루어져야 할 것이다. 또한 한국소비자들의 경우 사적대응행동을 많이 할수록 오히려 재구매의도는 낮은 것으로 나타났다. 사적행동으로는 소비자들의 불만이 기업에 반영되기 어려우므로 기업에서 소비자들의 잠재 불만을 파악하기 전에는 소비자들의 불만이 결국은 재구매 의도를 낮추는 결과를 가져올 것이므로 기업은 향후 공적행동과 함께 사적 불평행동에 대한 기업의 적극적인 파악 이 요구된다. Social Commerce market already has rapid grown and got strong spread for consumers` behavior in South Korea for consumption behavior. Aslo many consumers in China has almost same phenomenon in using social commerce near from big city. However, more problems such as service quality decline and consumers` complaints occurred as commerce market grows both in South Korea and China. This paper is related consumers` behavior using social commerce market. It reviews situation and explanation of current social commerce market both in South Korea and China. Consumers` dissatisfaction, complaints, repurchase intention were examined. This research especially focused for analyzing the differences for consumers` between South Korea and China. Survey using questionnaire was designed and conducted in October 6th -25th, 2011 for this study. The questionnaire were delivered to 20s` and 30s` South Korean and Chinese consumers through Internet. The total number of 382 consumers were used for this research. The survey was conducted Beijing, Xinjiang, Hebei and Shanghai in China. In South Korea, quesionnaire were delivered in districts Seoul, Inechon, Kangwando. The major findings of this research were as follows: First, Chinese consumers have more frequently visit, more purchasing behavior, more diverse items purchased were shown in social commerce than South Korean consumers. The level of dissatisfaction for social commerce was found higher in Chinese consumers. This result is supposed to be caused by larger rapid growth in internet shopping, home shopping. Second, Chinese consumers were reported to be more satisfied with social commerce than S. Korean ones, and this disparity is significant. Third, Chinese consumers committed more complaining behaviors than consumers in South Korea. This difference was verified to be significant. It is supposed that is caused lack of legal regulation on social commerce market in China, compared to South Korea. Fourth, Social Commerce consumer repurchase intentions were higher for consumers in China compare to South Korea. The number of purchases, number of visits per month were affect repurchase behavior in social commerce both in South Korean and Chinese consumers. Based on findings, this study propose some suggestions on improving consumer policy and education. First, because South Korean electronic trade is comparatively more developed and more policy-ruled than China, Related legal laws and regulations for consumer protection are insufficient in China, yet. As the market rapidly develop, more diverse, severe problems will arise. I is necessary for formulating related policies and laws especially in social commere market for protecting consumers. Second, it is necessary giving consumer education for consumers related electroing transaction because of rapid growth and professional knowledge for using social commerce. It is strongly recommended to express complaints through several channels such as company, non-government organization, government. Also it is necessary to educate consumers for dealing with dissatisfaction and resolve the problems.

Instrumentation of a Thermal-Optical Carbon Analyzer and Its Sensitivity in Organic and Elemental Carbon Determination to Analysis Protocols

( Ho Jin Lim ),( Su Hwan Sung ),( Sung Sin Yi ),( Jun Hyun Park ) 한국환경과학회 2012 한국환경과학회지 Vol.21 No.1

A thermal-optical transmittance carbon analyzer has been developed to determine particulate organic (OC) and elemental (EC) carbon. Several analysis factors affecting the sensitivity of OC and EC determination were investigated for the carbon analyzer. Although total carbon (TC) is usually consistent in the determination, OC and EC split is sensitive to adopted analysis protocol. In this study the maximum temperature in oxygen-free He in the analysis was examined as a main cause of the uncertainty. Prior to the sensitivity analysis consistency in OC-EC determination of the carbon analyzer and the uniformity of carbonaceous aerosol loading on a sampled filter were checked to be in acceptable range. EC/TC ratios were slightly decreased with increasing the maximum temperature between 550-800oC. For the increase of maximum temperature from 500oC to 800oC, the EC/TC ratio was lowered by 4.65-5.61% for TC loading of 13-44 μg/cm2 with more decrease at higher loading. OC and EC determination was not influenced by trace amount of oxygen in pure He (>99.999%), which is typically used in OC and EC analysis. The facing of sample loaded surface to incident laser beam showed negligible influence in the OC-EC split, but it caused elevated PC fraction in OC for forward facing relative to backward facing.

태양전지 응용을 위한 PECVD 실리콘 질화막 증착 및 열처리 최적화

Yoo, Jin-Su,Dhungel Suresh Kumar,Yi, Jun-Sin 대한전기학회 2006 전기학회논문지C Vol.55 No.12

Plasma enhanced chemical vapor deposition(PECVD) is a well established technique for the deposition of hydrogenated film of silicon nitride (SiNx:H), which is commonly used as an antireflection coating as well as passivating layer in crystalline silicon solar cell. PECVD-SiNx:H films were investigated by varying the deposition and annealing conditions to optimize for the application in silicon solar cells. By varying the gas ratio (ammonia to silane), the silicon nitride films of refractive indices 1.85 - 2.45 were obtained. The film deposited at $450^{\circ}C$ showed the best carrier lifetime through the film deposition rate was not encouraging. The film deposited with the gas ratio of 0.57 showed the best carrier lifetime after annealing at a temperature of $800^{\circ}C$. The single crystalline silicon solar cells fabricated in conventional industrial production line applying the optimized film deposition and annealing conditions on large area substrate of size $125mm{\times}125mm$ (pseudo square) was found to have the conversion efficiencies as high as 17.05 %. Low cost and high efficiency silicon solar cells fabrication sequence has also been explained in this paper.
