Fairy tales are rooted in folk tales and contain human unconsciousness and universal emotions. It also plays a role as original content in various narrative transformation works. Andersen's brings numerous signification through symbolic signs of red shoes, dance, and ankle amputation. Victor W.Turner's theory of social drama broadens the perspective of narrative analysis. In addition, this theory makes us realize the conditions of the social community required by society at the time. As a circular content, Andersen's shows the double entry narrative of growth as a woman and incorporation into the social community. In this process, the social conditions accepted and rejected are symbolically revealed. In Koo Byung-mo's novel , achromatic color and red color are contrasted. The red world is full of vitality and represents the meaning of human existence. Yoon Mi-kyung's fairy tale is divided into different characters from the girl's growth narrative and the outsider's entry into the women's society. This work accuses preconceived notions and prejudices against multicultural families and strangers.

This study aims to assess the problems with investigation method and to suggest the complementary solutions by comparing the predicted data from surface investigation with the outcome data from underground cavern. In the study area, one(NE-1) of 6 fracture zones predicted during the surface investigation was only confirmed in underground caverns. Therefore, it is necessary to improve the confidence level for prediction. In this study, the fracture classification criteria was quantitatively suggested on the basis of the BHTV images of NE-1 fracture zone. The major orientation of background fractures in rock mass was changed at the depth of the storage cavern, the length and intensity were decreased. These characteristics result in the deviation of predieted predicted fracture properties and generate the investigation bias depending on the bore hole directions and investigated scales. The evaluation of hydraulic connectivity in the surface investigation stage needs to be analyze by the groundwater pressures and hydrochemical properties from the monitoring bore hole(s) equipped with a double completion or multi-packer system during the test bore hole is pumping or injecting. The hydraulic conductivities in geometric mean measured in the underground caverns are 2-3 times lower than those from the surface and furthermore the horizontal hydraulic conductivity in geometric mean is six times lower than the vertical one. To improve confidence level of the hydraulic conductivity, the orientation of test hole should be considered during the analysis of the hydraulic conductivity and the methodology of hydro-testing and interpretation should be based on the characteristics of rock mass and investigation purposes.

조류의 배자는 포유류의 배자처럼 모체로부터 영양분을 공급받는 것이 아니라 알속에 저장되어 있는 영양물질로 발육한다. 배자의 발육은 대부분 체외에서 진행된다. 난자는 배란된 후 수정되어 난관팽대부에서 1세포기 수정란이 된다. 그 후 난관협부로 이동하여 최초로 분열이 일어나 배자의 발육이 진행되고, 산란시에는 세포수가 약6만여 개에 달한다. 따라서 수정란에 유전조작기법을 사용하기 위해서는 모체의 난관속에서 일어나는 배발생과 난각속에서 일어나는 개체발생을 위한 체외배양법과 대리난각 배양법이 확립되어 있어야 한다. 그와 같은 기술은 닭 수정란의 배 발생 관찰 및 분석과 유용한 물질을 생산하기 위한 형질전환 가금 연구에 중요한 기술로 사용되고 있다. 따라서 본 연구는 1세포기 닭 수정란의 체외배양과 대리난각 배양에 있어서 수정란의 조건과 대리난각의 조건이 배자의 생존율과 부화율에 미치는 영향을 조사하여 체외배양과 대리난각 배양에 의한 병아리 생산 효율을 제고하기 위한 기초자료를 얻고자 실시하였다. 주요 조사 항목은 수정란의 채란위치, 배자의 발생단계, 수정란의 무게, 대리난각용 계란의 보존 기간, 대리난각의 두께, 대리난각 두께의 감소율, 대리난각의 크기 등을 조사하여 배자의 생존율과 부화율에 미치는 영향에 대하여 조사하였다. 본 실험의 결과는 초기 발생이 빠른 배자가 생존율과 부화율이 높았으며, 본 실험에 사용한 대리난각용 계란의 보관기간이 짧을수록 배자의 생존율과 부화율이 높은 것으로 조사되었다(p<0.05). 그러나 대리난각용 계란의 크기와 대리난각의 두께 차이는 배자의 생존율과 부화율에 큰 영향이 없는 것으로 조사되었다.하였을 때 분할율은 68.0%였으며, 이중 12.0%가 상실배 또는 배반포로 발달하였다. 뿐만 아니라 10% FBS가 첨가된 TCM-199 배양액에 난관상피세포와 공배양을 실시하였을 경우는 72.0%가 분할하였으며, 이중 16.7%가 상실배 또는 배반포로 발달하였다. 이상의 결과로 볼 때 활성화 처리는 ionomycin과 6-DMAP 용액처리가 적합하며, 단위발생란의 체외배양은 보다 적합한 배양조건의 확립이 필요한 것으로 생각된다.icalcium lactate 공동배양은 체외배양에 별다른 영향을 미치지 못하는 것으로 나타났다.생산하는 것을 확인할 수 있었다.4시간에 등급별 회수율이 각각 GI(27.4%), GII(14.7%), GIII(43.2%), GIV(14.7%)로 나타났으며, 46~50시간에는 GI(12.0%), GII(12.0%), GIII(28.0%), GIV(48.0%)로 나타났다. 이상의 결과로 볼 때 미성숙 난자의 회수는 hCG 투여 후 29~34시간이 적합한 것으로 생각된다. 가금의 생산에 있어서 매우 효율적이고 주목할 만한 방법으로 사료된다. 것으로 나타났다.적외선.열풍 복합건조방법이 높게 나타나 이것은 곡물 표면에 원적외선 방사에의한 복사열이 전달되어 열장해를 받았기 때문으로 판단되며, 금후 더 연구하여 적정 열풍온도 및 방사체 크기를 구명해야 할 것이다.으로 보여진다 따라서 옻나무 유래 F는 포유동물의 생식기능에 중요하게 작용하는 것으로 사료된다.된다.정량 분석한 결과이다. 시편의 조성은 33.6 at% U, 66.4 at% O의 결과를 얻었다. 산화물 핵연료의 표면 관찰 및 정량 분석 시험시 시편 표면을 전도

For a social venture in early stage, it is very difficult to set up a strategy as it has to pursue two contradictory goals; economic value and social value. The platform strategy can be good alternative solution for social ventures as it seeks building-up connections with other businesses to co-create value despite of limited resources. A Korean social venture, JUMP! which adopted platform strategy in the early stage, and successfully applied 4 key factors of platform strategy; core competency, value creation ability, efficiency and network effect, has been able to develop sustainable growth for itself and induce innovation and growth among the participants within the platform. This study was intended to research effect of adoption and successful application of platform strategy for social ventures in the early stage of start-up and draw conclusion through case study that platform strategy works for sustainable growth of social ventures.

This study was initiated to explore the Christian educational challenges of building a "Peer Consciousness" in North and South Korea after reunification. During the period of division, North and South Korea have became heterogeneous in almost all elements of society, including politics, economy, culture, and education. Considering the various social conflicts that the two heterogeneous societies will experience in the process of reunification, the issue of social integration is no longer a side issue of institutional integration or economic integration, but has become an essential element in itself. This is why the Korean church and Christian scholars need to study in depth the social conflicts and integration issues that may arise before and after reunification. For the study, we analyzed the forms of social conflict based on the theory of ''Human Needs Theory', which states that human needs are the conditions for social conflict. Social conflicts stem from the unfulfillment of various human needs, which in turn extend to identity conflicts that seek to form a sense of belonging. In light of the case of unified Germany, where social conflicts converged into identity conflicts, I predicted that conflicts in unified Korea will soon become identity conflicts. The direction of Christian education that should suture the conflicts in the post-reunification society was derived from theological reflection on the concept of 'publicness of Christian education' and 'kingdom of God'. As a concrete educational plan for social integration, I presented the discourse of love of God and love of neighbor through Christian education for dual identity as a citizen and disciple, and emphasized the need for re-socialization education through faith communities

Purpose: Dual reporter gene imaging has several advantages for more sophisticated molecular imaging studies such as gene therapy monitoring. Herein, we have constructed hepatoma cell line expressing dual reporter genes of sodium iodide symporter (NIS) and enhanced green fluorescence protein (EGFP), and the functionalities of the genes were evaluated in vivo by nuclear and optical imaging. Materials and Methods: A pRetro-PN vector was constructed after separating NIS gene from pcDNA-NIS. RSV-EGFP-WPRE fragment separated from pLNRGW was cloned into pRetro-PN vector. The final vector expressing dual reporter genes was named pRetro-PNRGW. A human hepatoma (HepG2) cells were transfected by the retrovirus containing NIS and EGFP gene (HepG2-NE). Expression of NIS gene was confirmed by RT-PCR, radioiodine uptake and efflux studies. Expression of EGFP was confirmed by RT-PCR and fluorescence microscope. The HepG2 and HepG2-NE cells were implanted in shoulder and hindlimb of nude mice, then fluorescence image, gamma camera image and I-124 microPET image were undertaken. Results: The HepG2-NE cell was successfully constructed. RT-PCR showed NIS and EGFP mRNA expression. About 50% of cells showed fluorescence. The iodine uptake of NIS-expressed cells was about 9 times higher than control. In efflux study, $T_{1/2}$ of HepG2-NE cells was 9 min. HepG2-NE xenograft showed high signal-to-background fluorescent spots and higher iodine-uptake compared to those of HepG2 xenograft. Conclusion: A hepatoma cell line expressing NIS and EGFP dual reporter genes was successfully constructed and could be used as a potential either by therapeutic gene or imaging reporter gene.

In SCRamjet engine, combustion occurs in supersonic flow with airbreathing. SCRamjet is characterized by very short combustion time in combustor, so it is very important to be mixing the air and fuel in short duration. Several methods are suggested for mixing enhancement. Among these, cavity is selected to study for enhancement of mixing. The numerical simulation is performed in the case of freestream Mach number of 2.5 and cavity located in front of fuel jet injection. CFD-Fastran, commercial code with three-dimensional Navier-Stokes equation with the Menter SST turbulence model were used. The results are obtained validate experiment results for same condition. Therefore, the numerical results show the mixing enhancement characteristics with a cavity.

The World Wide Web (Web) is one of the most popular internet tool on now, In this reason most of common user, they understand the Web is internet and Web content is also important issues on this side. However, commonly Web content created by one of Web content creator and sometime they refer the another document and link. In these kinds of environments cause tile delivery of incorrect information or linking to another Web user. There are lots of way to protect the incorrect information deliveries to Web user and the most famous one is Computer Supported Cooperation Work (CSCW). This supports the multi-user environment on single system environment, but this needs more additional things in the current internet environment Current internet defined as distributed information network not tile traditional client-server environment. Specially, Intranet environments need to support the heterogeneous system environment like several Rinds of database, systems like PC, Mac and UNIX workstation, and etc. In this reason, we need collaboration and this would serve the common user interface to all of Web user. In these paper, we review the current concept of CSCW and grouoware that are major concept of collaboration and definition, classification and problem analysis of the collaboration. Finally, we suggest the construction method of collaboration environment for Web.

We herein present a study on the active phased array antenna for receiving satellite broadcasting that can electrically align its polarization to that of target transmitters in its moving condition or in the Skew angle arrangement of the broadcasting satellite receiver. Hence, we have developed an active phased array structure composed of the self-developed Vivaldi antenna and multifunction core (MFC) chip, receiving RF front end module, and control units. In particular, the new Vivaldi antenna designed in the Ku-band of 10.7 - 14.5 GHz to receive one desired polarization mode such as the horizontal or vertical by means of an MFC chip and other control units that can control the amplitude and phase of each antenna element. The test results verified that cross-polarization property is 20 dB or higher and the primary beam can be scanned clearly at approximately ${\pm}60^{\circ}$.

과거 한국의 식품 오염원 중 법적인 규제 등을 통해 구체적인 통제가 이루어지지 못하고 있는 것이 축산물의 항생제로 알려져 항생제 오 남용으로 인한 내성균의 출현으로 비상이 걸렸던 적이 있었다. 요즘은 항생제를 지나치게 많이 사용해 가축이나 인체 내의 병원성 미생물들이 내성이 생겨 문제가 되고 있어 2011년 7월부터 가축용 사료에 항생제 첨가가 금지하게 된다. 한국은 항생제 내성률 1위로, 2000년 세계보건기구(WHO)에 따르면 대표적 항생제인 페니실린에 대한 폐렴구균의 내성률이 70%로 세계 1위이다. 어느 보고서에 따르면, 축산물 1톤을 생산하는 데 사용되는 항생제가 스웨덴이나 뉴질랜드, 덴마크 등 축산 선진국이 31~44g에 불과한데 비해 한국은 911g에 이른다. 투여 경로는 배합사료에 포함된 양이 54%, 농가의 임의 치료가 40%, 수의사 처방은 겨우 6% 순으로 나타났다. 그러나 OECD 회원국 중 수의사 처방 없이 항생제의 임의 투여를 허용하고 있는 나라는 한국뿐이다. 세계보건기구(WHO)에서는 가축사료에 항생제를 첨가하지 말 것을 권장하고 있으며, 유럽연합(EU)도 항생제는 반드시 수의사의 처방에 의해서만 사용토록 제한하고 있다. 최근 국립수의과학검역원에 의하면, 축산용 항생제 사용량이 2008년에 비해 18%, 2001년에 l해 무려 38%가 감소되었으며, 이중 닭은 20%, 소의 항생제 사용량은 36%가 감소하였다고 밝혔다. 사육 가축들의 항생제 오남용을 줄이기 위해서는 사료에 첨가하는 항생제나 성장호르몬, 비소 투여 등의 투여 대신에 미생물 생균사료나 녹차사료, 한약재사료 등의 천연면역물질을 함유한 사료를 먹여 스트레스를 덜 받고 면역력 증강에 좋은 사료를 먹여 키운 건강한 가축으로 생산한 육류는 맛도 특별히 좋다. 본 자료의 대부분은 금년부터 3년간 농촌진흥청 국립축산과학원과 중국청도농업대학과 "고품질 축산물생산을 위한 중약제를 이용한 질병방지체제 연구"라는 과제로 공동협력연구를 수행하게 됨에 따라 지난 11월 4일부터 10일까지 필자가 중국 청도농업대학을 방문하여 세미나시 발표한 자료임을 밝혀두며, 국내 수의학 연구에도 도움이 되고 저 소개한다.
