Constant Shoulder Assessment(CSA), Shoulder Pain and Disability Index(SPADI), Range of Motion(ROM) and the patient's satisfaction concerning the treatment was measured by Visual Analogue Scale(VAS). DITI was measured before treatment and after 4weeks of treatment. The obtained data was analyzed. Results : CSA, SPADI, VAS, adduction and extension showed significant(p<0.05) improvement. Abduction and flexion both improved after 4 weeks of treatment, but the improvement was statistically insignificant(p>0.05). DITI showed improvement but the improvement was insignificant(p>0.05). Conclusion : 4 weeks of acupuncture treatment significantly improved CSA, SPADI, VAS, adduction and extension in frozen shoulder patients(p<0.05). The improvement of abduction and flexion after 4 weeks of acupuncture treatment was insignificant(p>0.05). DITI results improved after 4 weeks of acupuncture treatment. But the change of thermal difference was insignificant(p>0.05).

성장단계에 따른 중소기업의 네트워크 유형과 경영성과간의 관계에 대한 연구

이도형(Lee Do Hyung),김충현(Kim Choong Hyun) 한국경영교육학회 2012 한국경영교육학회 학술발표대회논문집 Vol.2012 No.6

신생기업은 태생적으로 자원이 부족하여 신생기업의 한계를 경험하게 된다. 이러한 한계를 극복하기 위하여 자신의 통제하에 있지 않은 자원을 보다 손쉽게 이용하고자 네트워크를 활용하게 된다. 이러한 네트워크는 기업들이 치열한 경쟁환경 속에서 살아남고 지속적인 성장을 가능케하며, 기업의 발전에 있어서 중요한 모델로 주목받아왔다. 하지만, 많은 연구들이 단일 혹은 제한된 네트워크에만 주목함으로써 네트워크의 효용성에 대해 많은 논란이 제기되고 있다. 더구나 기업들은 다양한 네트워크의 형태를 보유하고 있으며, 기업의 상황에 따라 그 중요성은 다르게 나타날 수 있다. 따라서 본 연구에서는 기업의 성장단계에 따라 네트워크 유형이 성과에 미치는 차별적 영향을 분석하기 위하여 국내 247개 기업을 대상으로 설문조사를 실시하였으며 실증분석 결과는 다음과 같다.첫째, 사회적 네트워크는 신생기업의 성과에 유의한 영향을 미치지 않는 것으로 나타난 반면, 성장기업의 성과에는 오히려 유의한 부(-)의 영향을 미치는 것으로 나타났다. 둘째, 평판 네트워크는 신생·성장기업 모두의 성과에 유의한 정(+)의 영향을 미치며, 신생기업의 성과에 더 큰 영향을 미치는 것으로 나타났다. 셋째, 정보 네트워크 역시 신생·성장기업의 성과에 정(+)의 영향을 미치며, 신생기업의 성과에 더 큰 영향을 미치는 것으로 나타났다.본 연구를 통하여 기업들, 특히 신생기업들은 높은 평판을 보유하고 있는 기업들이나 혹은 시장에 대한 정보를 제공해줄 수 있는 기업들과 관계를 맺는 것이 시장에 긍정적인 신호효과와 정당성을 확보하는 데 도움을 주어 결과적으로 기업의 성과를 향상시켜 줄 것이다. 즉 기업가의 개인적 관계보다는 평판이 높은 기업 혹은 정보를 제공해줄 수 있는 기업과의 관계를 맺는 것이 성과에 도움이 될 수 있다는 것을 시사해주고 있다. New start-up firms are more likely to experience liability of newness because of scarce resources. In order to overcome these limitations and to make utilization of resources which are not under their direct control, they try to build networks which are known as contributing to achieving firm performances. Although many studies have been done so far, however, they have been so much focused on one or limited networks that there is still strong debate about their utilities. Furthermore, firms have various networks and their importance can vary according to firms' situations. Thus, this study aims to empirically analyze the effects of network types on firm performances throughout growth stages. For this, questionnaire surveys were administered targeting 247 companies that operate their businesses in Korea. The followings are found:Firstly, it was found that social networks don't have any effects on start-up firms' performances while they have significantly negative effects of growing firms'. Secondly, reputation networks are found to have significantly positive effects on both start-up and growing firms' performances while they have more effects on start-ups. Thirdly, information networks are also found to have the same effects as reputation networks do.Through this study, we found that if firms and especially start-ups establish sound and good networks or partnerships with those with good reputations or those which can provide useful market information, they will have positive signalling effects and obtain legitimacy which in turn improve their performances. In other words, this study implies that establishing networks with those with good reputations or informations will help start-ups to achieve high performances rather than social and personal networks.

헬기의 능동진동제어시스템(AVCS)은 주로터로부터 발생되는 진동을 제어하며, 수동형 진동저감장치 대비 저중량으로 우수한 진동저감 성능을 발휘한다. 본 논문에서는 FxLMS 알고리즘을 기반으로 타코미터 및 가속도 센서 신호를 통해 연산된 제어명령을 하중발생기(CFG)로 전달하여 소형 민수헬기의 진동을 제어하는 소프트웨어 개발 및 검증 내용을 제시하였다. DO-178C /DO-331 표준에 따라 모델 기반 설계 기법을 통해 진동제어 소프트웨어를 개발하였으며, PILS 및 HILS 환경에서 실시간 작동 성능을 평가하였다. 특히, PILS 환경에서는 LDRA 기반 검증 커버리지를 통해 소프트웨어의 신뢰성을 향상시켰다. AVCS를 소형민수헬기에 적용하기 위해 지상/비행시험을 통해 대상 헬기 동적응답특성 모델을 획득하였다. 이를 기반으로 시스템 최적화 분석 및 비행시험을 통해 최적 성능을 발휘하는 AVCS 형상을 결정하고, STC 인증을 획득하였다. Active vibration control system(AVCS) for helicopter enables to control the vibration generated from the main rotor and has the superb vibration reduction performance with low weight compared passive vibration reduction device. In this paper, FxLMS algorithm-based vibration control software of the light civil helicopter tansmits the control command calculated using the signals of the tachometer and accelerometers to the circular force generator(CFG) is developed and verified. According to the RTCA DO-178C/DO-331, the vibration control software is developed through the model based design technique, and real-time operation performance is evaluated in PILS(processor in-the loop simulation) and HILS(hardware in-the loop simulation) environments. In particular, the reliability of the software is improved through the LDRA-based verification coverage in the PIL environments. In order to AVCS to light civil helicopter(LCH), the dynamic response characteristic model is obtained through the ground/flight tests. AVCS configuration which exhibits the optimal performance is determined using system optimization analysis and flight test and obtain STC certification.

2000년 4월경부터 (수온7-13℃) 우리나라 동해안과 남해안 육상 수조에서 사육되던 넙치에서 체색흑화, 복수저류, 비장종대의 육안적 소견을 보이는 질병이 발생하여 대량폐사를 불러왔다. 병리조직학적 소견으로, 비장과 신장의 조혈조직에서 괴사병변이 주로 나타났다. 비장과 신장의 간질조직에서 괴사소가 관찰되었으며, 임파구, 괴사세포의 침윤이 나타났다. 비장 조직의 전자현미경적 관찰에서 변성혈구 내 세포질에서 탄환형의 바이러스 입자가 관찰되었는데 직경과 길이가 각각 약 50nm, 170nm였다. 이상의 결과로 본 질병은 rhabdovirus에 의한 질병으로 판단되었다. On April of 2000 and February of 2001, a disease characterized by darkening, ascites and enlargement of the spleen occurred in flounder, Paralichthys olivaceus, farmed near northern and eastern coasts of Korea. Various degree of necrosis including liquefactive-type was observed mainly in hemopoietic tissue of spleen and kindney. Certain tissue such as branchial soft tissue including epithelium showed a similar necrotic findings. But some tissues such as intentine had several necrotic clusters of wandering cells, being possibly leukocytes. Necrotic evidences of blood cells were evident in various tissues including hemopoietic tissues. Necrobiotic bodies were frequently encountered in blood smear preparations. Bullet type-virious were detected in the spleenic cells. Each virion was about 500 nm in diameter and 170nm in length. From these results, this disease was thought to be a rhabdoviral disease.

韓國 地方政府의 綜合的 改革方向 : Toward Efficacious Public Service Delivery Systems 效率的인 公共서비스 生産 및 傳達體系로서의 轉煥을 중심으로

李都炯 忠州大學校 1996 한국교통대학교 논문집 Vol.31 No.1

In the era of local self-government, we anticipate that our local governments should be efficacious public service delivery systems, for we are confronted by many local living difficulties. But our existing self-governing bodies are by no means useful public service delivery systems. They cannot satisfy citizen's service demands owing to their unfinished, overworked organizational structures. They cannot timely provide services because of their complicated, fussy operating procedures. Moreover our local administrators are too incompetent to solve many local problems, and they are used to the maintenance of the status quo. In addition, our local governments' scale must be resized so as not to become fat. Accordingly, we must make a radical and comprehensive reform on our self-governing bodies. A series of re-ings, i.e. re-thinking, re-structuring, re-engineering, re-sizing, re-skilling can contribute to the perfect redesign of our local governments in that they are applicable to the establishment of client-oriented, efficient, and timely service administration. Therefore, we must apply re-ings to the reform of our local governments so that they can be converted into efficacious public service delivery systems.

Xenotransplantation of porcine organs has the potential to overcome the severe shortage of human tissues and organ available for human transplantation. however, it remains various hurdles for clinical xenotransplantation. In pig and mouse xenotransplantation, porcine xenograft evoke a strong cellular rejection response in immunocompetent host and grafts are destroyed within a week. This cellular immune response could involved both T cells and NK cells. A number of groups have shown that human NK cells can recognize and damage porcine endothelial cells. In addition, human T cells can respond to porcine endothelial cells through both direct and indirect mechanisms. Cellular rejection of porcine tissues requires T cells, particularly CD4^(+) cells. A new cytokine recombinant human interleukin-32α,β(IL-32α,β) has a role innate and acquired immune system. In order to investigate the role of recombinant mouse IL-18 and recombinant human IL-32α,β in xenograft rejection, we transplanted the PK(15) cells to C57BL/6 mice with or without intraperitoneal injection of recombinant mouse IL-18 or recombinant human IL-32 α,β. It was analyzed the population of NK cell, T cell and B cell in the C57BL/6 mice transplanted with PK(15) cells and recombinant mouse IL-18 or recombinant human IL-32α,β by flow cytometry analysis. As a result, lymph node and thymus of PK15/IL18, PK15/IL32α and PK15/IL32β injected group were increased to T cell activation population than normal injected groups. CD8^(+) T cells were decreased in lymph node of PK15/IL18, PK15/IL32α and PK15/IL32β injected groups. CD4^(+) T cells were increased in lymph node cell of PK15/IL32α and PK15/IL32β injected group and also, B cell population were increased in lymph node cell and spleen of PK15/IL18, PK15/IL32α and PK15/IL32β injected group. Therefore, we suggest that recombinant mouse IL-18 and recombinant human IL-32α,β suppress xenograft rejection in cellular xenotransplantation.
