  • 목적 : 전통적으로 태충($LR_3$)과 양릉천($GB_{34}$)은 운동기능과 관련된 질환에 사용되어 왔다. 우리는 두뇌에 신경독을 주입하여 파킨슨병 쥐모델을 제작하였고, 쥐는 운동기능이 손상되고 도파민성 신경세포가 선택적으로 소멸하였다. 병증 모델 쥐에게 태충과 양릉천에 자침한 결과 운동기능이 개선되고 신경세포보호효과가 나타남을 관찰한 바 있다. 이에 실제로 태충과 양릉천에 자침하여 운동기능과 관련된 추체외로 영역에서 신경의 활성화가 나타나는지를 fMRI를 통하여 관찰하였다. 방법 : 자침은 수기침을 선택하였으며, 혈위는 (1) 태충, (2) 양릉천, (3) 태충+양릉천의 세군데를 설정하였고, 자침에 대한 대조자극으로 피부자극을 채택하였다. fMRI 스캐너는 3T를 사용하였고 뇌신경 활성화의 신호는 BOLD(blood-oxygen-level dependant)를 관찰하였다. 두뇌에서 관찰부위는 중뇌를 중심으로 추체외로로 한정하였다. 결과 : 태충에 자침하였을 때 두뇌의 substantia nigra, subthalamic nucleus, red nucleus, pons 등이 활성화 되었다. 양릉천에 자침하였을 때 substantia nigra, subthalamic nucleus, caudate nucleus, thalamus가 활성화 되었다. 태충과 양릉천에 동시에 자침하였을 때는 substantia nigra, subthalamic nucleus, red nucleus, globus pallidus가 활성화되었다. 대조자극에 의해서는 위의 영역들이 활성화되지 않았다. 결론 : 태충, 양릉천, 태충+양릉천 자극은 대뇌에서 추체외로 영역을 활성화시키며 특히 substantia nigra의 활성화는 파킨슨병과 같은 질환의 조절가능성을 시사한다.

  • The aim of this study was to apply the Importance-Performance Map (IPM) method based on PLS-SEM by extending the importance-performance analysis (IPA), which is an existing method to grasp strategic policies through the difference of importance and satisfaction of existing competitiveness factors. For this application, this study was applied to research related to policy measures that can survive and spread in global competition by analyzing strategic factors of information technology (IT) convergence industry. The development of IT convergence industry, which is the subject of this study, has the effect of revitalizing related industry development and employment activation. Therefore, this study expanded the possibility of applying this research methodology to research the strategic factors to activate exports of SMEs (Small and medium-sized enterprises) in the convergency industry. In order to achieve this goal, the analytical methodology of this study was applied and the policy measures for IT SMEs. Therefore, based on the analysis results of this study, this study can apply this research methodology to other fields as a strategic tool in establishing and enforcing policies for export activation of IT convergence industry.

  • It is necessary to develop a bridgehead port for trading with northern countries to promote trade through the East Sea because the East Sea Rim economic bloc around the Northeast Asia including South Korea, China, Russia, Japan, and North Korea has a high growth potential in the future. Therefore, this study aims to suggest a strategic direction to enhance the competitiveness of Donghae Port through reinforcement of container cargoes by conducting Importance-Performance Analysis (IPA) for stakeholders of Donghae Port. The analysis results suggest that it is necessary to improve the five evaluation factors: attractiveness of container and bulk volumes, appropriate ratio of export/import container quantities, frequency of vessel entry and diversity of sea routes, convenience of complex linked transportation, and competitiveness of cargo handling equipment. The implications of this study are as follows. First, it is necessary to continuously research the current status of container and bulk cargo volumes of the port and ways to increase the absolute cargo volume. Second, we need to consider realistic alternatives to improve the ratio of export/import container quantities. Third, in terms of network, we should establish a service improvement plan to increase the frequency of port calls and the diversity of sea routes. Furthermore, incentives should be provided to increase the trade volume of Donghae Port through strengthened complex linked transportation function. Finally, it is urgently necessary to provide investment support for container handling equipment as an essential requirement for the activation of the container cargoes in Donghae Port.

  • Those who supply the consumer with the culture and the sharing of feelings can be. The code to be read correctly by the consumer unless it is impossible the formation of the culture. The dissemination of this vibrant ceramic culture is the power of education can be. In this sense, our ceramic culture also reaffirming the importance of education and overhaul is needed. Times the local ceramic arts in order to become as a culture, above all, education and activation are required. We run workshops in teaching methods and ways to activate based on the importance of education policy based on the Revitalization of ceramic culture is suggested.

  • The effect of the surface activation treatment on the crystallization of the amorphous silicon film was investigated. The amorphous silicon film was deposited on the silica substrate with LPCVD technique. Wet blasting with silica slurry or exposure with Nd:YAG laser beam was applied on the amorphous silicon film before annealing for the crystallization. For the analysis of the crystallinity, XRD, Raman, and SEM were employed. In this investigation, the prior surface activation treatment like silica wet blasting or Nd:YAG laser beam exposure before annealing for the crystallization were found to be effective in the enhancement of the crystallization. It is believed that these treatment lower the activation energy required for the crystallization of the amorphous silicon film.

Hoffmann, 그리고 수지상세포(樹枝狀細胞)(dendritic cell; DC)발견과 적응(適應)(획득)(獲得)면역(免疫)(adaptive immunity)에 있어서의 그들 세포의 역할을 밝혀낸 R. M. Steinman의 공동수상으로 금년도 Nobel 생리 의학상 수상자가 결정되었다는 보도가 지난 10월 3일 있었다(1-3). 그들의 업적을 요약하면 대략 다음과 같다. (Steinman교수는 Nobel수상자 발표 3일전인 9월 30일 암으로 사망함). 그들은 면역기구(immune system)의 활성화의 관건(key)이 되는 원리를 밝혀냄으로써, 면역기구에 관한 우리들의 이해를 혁신하였던 것이다. 과학자들은 오랫동안 세균(bacteria)이나 기타 미생물병원체들에 의한 공격에 대비하여 그들 자신을 방어하는 사람이나 기타 동물체에서의 면역응답(免疫應答)(immune response)의 문지기들을 탐색해 왔다. Beutler와 Hoffmann은 그와 같은 병원미생물을 인식하여 생체의 면역응답의 첫 단계인 자연면역을 활성화 할 수 있는 수용체 단백질(toll-like receptor protein)을 규명한 것이다(4,5). 한편 Steinmann은 면역계의 수지상세포(DC)와 병원미생물이 생체로부터 배제되는 면역응답의 후기단계인 적응면역을 활성화하고 조절하는 그들의 독특한 재능을 규명해 낸 것이다(6-8). 그들 3명의 발명은, 면역응답의 자연 및 적응 양상(樣相)이 어떻게 활성화되는 가를 밝혀냄으로써 질병의 기전에 관한 참신한 식견(識見)을 제공한 것이다. 그들의 연구는 감염병(感染病)(infectious disease), 암(癌)(cancer) 그리고 염증성질환(炎症性疾患)(inflammatory disease)에 대응하는 예방과 치료의 개발을 위한 새로운 방법을 개척한 것이다.

  • The activation energy of CPVC (Chlorinated Poly Vinyl Chloride) used for non-metallic synthetic resin piping in fire-fighting was measured by thermogravimetric analysis (TGA). The activation energy was determined using by TGA kinetic methods, such as Kissinger and Flynn-Wall-Ozawa method. The calculated activation energy was 128.07 kJ/mol (Kissinger method) and 145.60 kJ/mol (Flynn-Wall-Ozawa method). The difference in activation energies calculated by the Kissinger method and Flynn-Wall-Ozawa method was not considered to be significant considering that the different analysis methods. The combustion characteristics will be tested in a future study through an evaluation of thermal deterioration using an accelerated deterioration and air oven aging test and the lifetime of CPVC will be predicted.
