Osteocalcin과 융합한 FibronectinIII9-10 단백질 특성 및 발현 연구
Fibronectin은 세포외 기질에 존재하는 다기능성 당단백질로, 세포 부착과 관련하여 중요한 역할을 하고 있으며, 세포 성장에도 관여 하고 있습니다. 그리고 osteocalcin은 뼈의 무기화와 골격 교체에 관련되어 있는 단백질로 알려져 있습니다. 이 실험에서는 이러한 두 단백질을 융합하여 실험하였으며, 융합 단백질의 발현의 최적 조건을 찾고 MC3T3-E1 세포를 이용하여 세포의 활성 및 골분화를 확인하였습니다. Recombinant human osteocalcin-fibronectinIII9-10 (rhOCN-FNIII9-10)의 최적의 발현 조건은 0.1% (w/v)의 L-arabinose 농도, 20 ℃의 온도에서 2시간 동안 배양 하는 것으로, 이 조건에서 rhOCN-FNIII9-10이 가장 많이 발현을 하는 것을 확인하였습니다. 그리고 MC3T3-E1를 이용한 실험에서, 세포의 부착 활성과 세포 증식 또한 rhOCN-FNIII9-10에 의해 증가하는 것을 확인할 수 있었으며, rhOCN-FNIII9-10에 의해 골분화가 활성화됨을 확인 할 수 있었습니다. 이러한 실험 결과를 통하여 rhOCN-FNIII9-10의 뼈 조직과 치아 조직 공학에서의 이용에 도움이 될 것으로 생각됩니다. Fibronectin (FN) is a major adhesive component of extracellular matrix (ECM) and is involved in osteogenesis as well as cellular growth. Osteocalcin (OCN) is also related to bone metabolism. I determined optimal culture condition for rhOCN-FNIII9-10 expression in Escherichia coli (E. coli). In addition, cell adhesion activity of purified rhOCN-FNIII9-10 under optimal culture condition was investigated. rhOCN-FNIII9-10 protein expression was the highest at an L-arabinose concentration of 0.1%, an induction temperature of 20 °C and an induction time of 2 h. In addition, purified rhOCN-FNIII9-10 protein significantly increased the adhesion activity and cell proliferation on MC3TC-E1 cells. And the osteogenic differentiation effect was investigated.
In order to get a student to speak a foreign language, he must be trained in communication practice in addition to pattern practice. Communication-oriented methods are to cover the weak points of traditional approaches: Grammar-translation, audiolingual method and cognitive code-learning theory. The author intends to research on four communication- oriented approaches: Situational Reinforcement Method, Audio-visual Method, Microwave Method and Lipsons Method. a) Situational Reinforcement Method The Situational Reinforcement Method devised by the Institute of Modern Ianguages in Washington, D.C. attempts to lead students to genuine communication by using a combination of drills. Situational teaching seems to work well mainly because the relevant material the students study fosters transfer to real communication about the subjects they learn. b) Audio-visual-structural-global Method This method was designed and implemented in France in a course called Voix et Images de France. It has been developed by the Center for Curriculum Development in Philadelphia. The method consists of four basic steps. Presentation, Explanation, Repetition, and Transposition. In Voix et Images the dialogues are illustrated with carefully constructed film strip and tape. c) Microwave Method. The distinctive: feature of a "microwave" course is the emphasis on communicative use of each structural element as soon as it appears. The principal components is a series of "cycles" which, because of their extreme shortness, have been given the name "microwave". Each cycle begins with the introduction of near material and ends when that same material has been used for purposes of communication. d) Lipson's Method The purpose of Lipson's Method is to motivate students to create their own sentences through the desire to communicate specific information. The technique has two steps: Presentation of a plot, and questions about the plot. In the very first lesson a cropus of sentences is learned through choral repetition and translation. Drawings or symbols replace translation almost immediately. In this Lipson's method, in order to maintain interest in classroom activity, humorous, almost surrealistic plots are created. e) Common features of Communication Techniques. (a) Communication-oriented approach-pattern practice is not enough. (b) Language activities should be done in the actual communicative situation. (c) The language of instruction is the target language (direct method). (d) Avoid mechanical recitation of patterns. (e) From teacher-centered to student-centered-evoke students' interest. Let the students discover their own ways of learning. In sum, this thesis has attempted to describe and evaluate four language teaching methods that are expressedly communication oriented. Teachers interested in providing communication practice for their students can add or adapt these techniques without necessarily changing the format of the course they are now using. In conclusion., the author would like to suggest (a) The drills should be not only mechanical but also meaningful and communicative. (b) More communication-oriented curriculum revisions are needed. (c) It is a dangerous thing to believe in the tenets of only one method and disregard the merits of the others (no panacea). (d) It is somewhat difficult to apply communication techniques to TESOL in Korea because of large class size, teacher's lack of skills in English and lack of incentives in students' using their communicative skills in actual life. However, we must keep on with the slow strides toward the improvement of TESOL in Korea through::. communication techniques. (e) Communication technique deserves further examination.
SP시험과 유한요소해석에 의한 경량화 AM60B 마그네슘합금의 기계적 특성평가
As the technology development and industry development were accelerated after the middle of 20 century, it was raised to the social problem that earth environmental pollution and an fossil fuel exhaustion that is the main energy source. Magnesium alloy is the material in which the lightness, the specific strength , the non-rigid, the damping capacity and the shielding. Also it have various strength such as the high effectiveness and the energy-saving of machinery. In recent years, the attention about magnesium alloy increases and the lightness necessity in automotive industry enlarges. Especially, in the automotive industry that is the main factor of the air pollution, the necessity of a lightweight is very enlarged and it is considered as the material replacing the aluminum alloy. Thus, in this paper, the behavior of the commercial AM60B magnesium that the mechanical property was excellent and widely used to the lightweight alloy was researched. In case of the commercial AM60B alloy, in comparison with AZ91 magnesium alloy, ductility a bit increased but it brought the strength decreased because of reducing the aluminum. Therefore this paper try to form the reinforcement of AM60B alloy by adding the Sn or Zn element in order to supplement the relatively strength reduction. Also this paper conducts SP test and Charpy impact test to understand mechanical property. SP test was conducted at load speed 0.2, 2, 20mm/min in room temperature and it deducted to fracture deformation and energy. Also, the behavior of AM60B magnesium was researched by testing the SP in 100°C, 200°C, 250°C temperature. So, we researched deformed AM60B alloy which the microstructure and fracture plane through scanning electron microscope and optical microscope. And we design widely used vehicle inner door panel and implement finite element analysis base on data derived from sp test. As a result, according to load speed, we catch the different of AM60B magnesium deformation behavior. And we see that the gap of strength is not only depend on the size of impact bar and braket but also the load speed as important parameter. The main test results are summarized as follow. 1. The magnesium AM60B was mainly comprised of the magnesium phase and eutectic MgAl at the grain boundary and the addition of 1% Sn, Zn refines the grain boundary. And it affects the strength of AM60B. 2. Although it is better for strength to be addition SP load speeding much higher, the improvement of tensile rate much lower until the addition of 1% Zn and Sn. And in over the addition of 1% Zn and Sn, the many eutectic compounds were created and it makes strength reduce drastically and a bit. 3. Also the fracture energy fairly increased when the SP load speed increases or the 1% Sn, Zn adds. This trend is similar to the strength. 4. In case that 100°C, 200°C and 250°C temperatures increases, all strength of test pieces were decreased. The addition of Sn1% in AM60B show the greatest of specimen within 150°C. But when the temperature is over the 150°C, the addition of Zn1% in AM60B Mg alloy strength surpassed the AM60B+Sn1% alloy. 5. In case of Charpy impact test, AM60B+Sn1% and Am60B+Zn1% show excellent impact absorptance. It has tendency of consensus with SP test result. 6. In the way of the FEM analysis, if the AM60B + Sn1% apply to the automotive inner door panel, it may have better strength of inner door panel in comparison of AM60B. Through the results, the SP test, Charpy impact test and FEM can be proved as a useful method for micro mechanical property evaluation of AM60B. Especially, the addition of 1% Sn or Zn will improve the mechanical property of AM60B magnesium alloy. Therefore, if the efforts of securing the safety without costs and sacrifices of mechanical property are continued, its can be expected unlimited growth of the magnesium alloy.
수도권 미이용 열원을 활용한 집단에너지사업의 경제적 타당성 분석
There exist the energy cooled from condensers following electricity generation in liquefied natural gas-based combined cycle power plants, heat of exhaust gas emitted from stack, wasted heat from electric furnace and heating furnace at steel mills, and heat energy arising from the process of incineration of waste and detritus in western boundary parts of the Metropolitan area (e.g., Incheon, Ansan, etc). Because these energies decentralized and independently operated in each area, currently they are not efficiently utilized. Therefore, this paper attempts to present the measures to utilize the unused heat sources in the Metropolitan area for the integrated energy businesses (IEB) and report the results from the feasibility analysis of the utilization in terms of nation and society. This study has been conducted based on the following methodologies and procedures. First, the types and scales of the unused heat sources scattered in western boundary parts of the Metropolitan area are investigated through visits to relevant companies and interviewing them with a survey instrument. Second, the methods of collecting the unused heat sources that are suitable for the characteristics of facilities of those who produce the unused heat sources are proposed and the amount of the collectable unused heat sources are computed considering the characteristics of facilities of heat sources and rates of operation. Third, the demand and demander for the unused heat sources are identified. The definite demand for the unused heat sources is estimated using visits to relevant IEB operators and interviews of them with a survey instrument since the unused heat sources will be used in current IEBs. In addition, the potential demand for the district heating system switching from current individual gas heating system or central heating system is calculated based on the principles of estimating heat demand in multi-unit dwelling area. Fourth, the author addresses the methods of utilizing the unused heat energy for IEB through establishing the wide heat network by examining the locations of the generators of unused heat energy and existing IEB operators. Fifth, the economic feasibility analysis of the utilization of the unused heat energy for IEB is performed using the Korea Development Institute’s guidelines for ex-ante evaluation of feasibility of the projects conducted by public utilities or enterprises from the standpoint of network business or wholesaler. Moreover, the methods of utilizing the unused heat sources for IEBs are analyzed and looked into. The results of the feasibility analysis of an integrated energy business project utilizing the unused heat sources in the Metropolitan area show that the benefit/cost ratio and internal rate of return are computed to be 1.72 and 24.26%, which are greater than 1.0 and 5.5%, social discount rate, respectively, and thus the project is socially profitable. Some important judgments can emerge from the results. The measures of utilizing waste heat energy emitted from factories of industry and/or incineration plants in western boundary parts of the Metropolitan area should be pro-actively taken. Making the loop of wide heatpipe network through heat networking linking GS Power Corporation and Ansan City Development Corporation located in Inchoen-Mokdong-Sadang block proposed in this paper should be also considered for implementation. Moreover, taking the actions to uncover and utilize unused heat energy in other areas of the nation as well as the Metropolitan area should be needed. 수도권의 서부 외곽지역(인천, 안산 등)에는 발전 전용 LNG 복합화력발전소에서 전기를 생산한 후 복수기(復水器)에서 냉각되는 에너지, 연돌(Stack)에서 대기로 배출되는 배기가스열과 제철소에서의 전기로 및 가열로에서의 폐열, 폐기물을 소각하는 과정에서 발생하는 열에너지가 존재한다. 이들은 각 지역별로 분산되어 각각 독립적으로 운영되고 있어, 발생하는 열에너지가 효율적으로 활용되고 있지 못하고 있다. 따라서, 본 논문에서는 재활용되지 못하는 열에너지를 집단에너지사업에 활용할 수 있는 방안을 제시하고 국가ㆍ사회적 관점에서의 경제적 사업 타당성 분석을 통해 실현 가능성을 제시하였다. 본 연구는 다음과 같은 연구방법 및 절차에 의해 수행되었다. 첫째, 수도권 서부 외곽 지역에 산재된 활용 가능한 미이용 열에너지의 종류와 규모 파악은 관련 업체의 방문 조사 및 서면 조사를 통해 시행하였다. 둘째, 미이용 열에너지 발생처의 설비특성에 적합한 미이용 열에너지 회수방안을 제시하고 열원의 설비특성 및 가동률을 고려하여 회수 가능한 미이용 열에너지의 규모를 산정하였다. 셋째, 미이용 열에너지를 재활용하기 위한 열수요처와 열수요량에 대한 조사를 시행하였다. 미이용 열에너지를 집단에너지사업에 활용할 계획이므로 열수요처는 기존에 집단에너지사업을 시행하는 업체를 대상으로 방문 조사 및 서면조사를 시행하여 “유력수요량”을 산정하고, 추가로 공동주택 밀집지역을 대상으로 열수요 선정기준을 제시하여 향후 개별난방이나 중앙난방을 지역난방 방식으로 바꿀 가능성이 있는 공동주택을 대상으로 “잠재수요량”을 산정하였다. 넷째, 미이용 열에너지 발생처와 기존 집단에너지사업자의 위치에 대한 현장 답사를 통해 “광역 열네트워크” 구축을 통한 미이용 열에너지를 집단에너지사업에 활용하는 방안을 제시한다. 다섯째, 미이용 열에너지를 집단에너지사업에 활용하는 것에 대한 국가ㆍ사회적 경제적 사업타당성 여부를 확인하기 위해 광역 열네트워크를 건설ㆍ운영하는 “망사업자”를 기준으로 하여 한국개발연구원의「공기업ㆍ준정부기관 사업 예비타당성조사 수행을 위한 일반지침 연구」를 기준으로 적용하고, 미이용 열에너지의 집단에너지사업 활용 방안에 대하여 분석 검토하였다. 수도권 미이용 열원을 활용한 집단에너지사업에 대한 비용-편익 분석을 수행한 결과, 편익/비용 비율은 1.72로 1.0을 상회하며 내부수익률은 24.26%으로 사회적 할인율인 5.5%를 훨씬 넘어 상기 사업은 경제적 타당성을 확보하고 있음을 알 수 있다. 연구 결과를 바탕으로 수도권 서남부 외곽 지역의 산업체 폐열과 소각장 폐열을 활용하는 방안을 적극적으로 모색하고 더불어 본 연구에서 제안한 인천~목동~사당구간 남쪽에 위치한 GS파워와 안산도시개발과의 열연계를 통한 광역 열배관 네트워크의 환산망의 구성 또한 검토할 필요가 있다. 또한, 수도권 뿐만 아니라 전국적으로 미이용 열에너지를 발굴하여 활용하는 방안을 강구할 필요가 충분히 있다고 판단된다.
