Eight cases of Myositis Ossificans observed in paralytic patients were studied. The original lesions leading to the paralysis were Cord Injury(4), C.V. A.(2), and Coma of various causes(2). The results were as follows; 1) In half of all, the occurrence of the ossification ranged between 3 and 4 weeks after the initiation of passive exercise. 2) The most frequent site of the lesion was the paraarticular area. 3) To cessation of passive exercise the lesion responded with prompt decrease in size. 4) It seems that as in normal ossification the repair process of aseptic inflammation derived from the bleeding or the hematoma formation may be the main etiological factor of this lesion in paralytic patients whom the passive exercise were forced.

본 연구는 바이오기업의 외부 네트워크 전략을 공동연구 협력, 제조/마케팅/판매 제휴, 자금지원, M&A 등 4가지로 구분하고, 이와 같은 바이오기업의 외부 네트워크 전략이 기업의 성과에 미친 영향을 살펴보기 위하여 미국 바이오기업 패널자료를 사용하여 분석한다. 첫째, 기술개발 이후의 제조/판매/마케팅 제휴는 단기간에도 모든 기업성과를 증진시키는 역할을 하였다. 둘째, 기술개발단계에서의 연구개발협력 중 제약회사와의 협력은 1~2년 이후의 기업성과에, 그리고 타 바이오기업과의 연구개발협력은 2년 이후의 기업성과에 정의 효과를 가져왔다. 셋째, 가장 장기적이며 기초연구에 주목적을 두고 있는 공공기관 및 대학과의 공동연구 협력은 단기적인 기업성과에 부정적으로 작용하여, 향후 2~3년이 아닌 보다 장기적인 관점에서 재조명되어야 하는 것으로 나타났다. 이러한 실증분석 결과는 국내 바이오산업의 발전을 위하여 외부 네트워크 전략을 통하여 기술혁신을 경주하는 노력이 필요하며, 또한 주로 기초기술에 집중된 공공기관과 대학과의 공동연구를 지원하는 정책적 고려가 필요함을 시사한다. Firm`s social network has been known as an important firm strategy because it could promote technological innovation and also minimize economic uncertainty. In this study, we identify four types of firm`s social network activities such as Collaboration, Manufacturing/Marketing/Distribution Agreements, Financing, and M&A, and analyze how these activities affect firm performance using U.S biotechnology firm data. We found that Manufacturing/Marketing/Distribution Agreements increased firm performance in short-run. Also, collaboration with pharmaceutical and biotechnology firms had a positive effect on firm performance, too. However, collaboration with public institutes or universities had a negative effect on firm performance in short run, which implies its collaboration would be mainly focused on research in pure science area. These empirical results provide two policy implications. First, social network strategy should be encouraged in the Korean biotechnology industry. Secondly, governments should consider developing polices that support collaboration of biotechnology with public institutes or universities, to promote technological innovation.

The natural fondness for physical beauty make people try to make themselves look good. This sence for beauty and the efforts to maintain or mprove oone'beauty have been constant throughout the ages. Fashion and make-up were developed as the methods of expressing this sense of beauty. The Make-up expressions that was shown on fashion was not won. that wasnatural to easily go well with any Bohemian style and the fact that the unique creative make-up that was pesfeofly matched and hamonized with the presentation techiniques applying various matherialls and the harmony of techniques was recognized. provide plentiful information and ideas to in future collection and make-up expression of the world.

During the shift from gasoline vehicles to electric ones, auto parts manufacturing companies have realized the importance of improvement in the manufacturing process that does not require any layout changes nor extra investments, while maintaining their current production rate. Due to these reasons, for the auto part manufacturing company, I-company, this study has developed the simulation model of the PUSH system to conduct a process analysis in terms of production rate, WIP level, and logistics work’s utilization rate. In addition, this study compares the PUSH system with other three manufacturing systems -KANBAN, DBR, and CONWIP- to compare the performance of these production systems, while satisfying the company’s target production rate. With respect to lead-time, the simulation results show that the improvement of 77.90% for the KANBAN system, 40.39% for the CONWIP system, and 69.81% for the DBR system compared to the PUSH system. In addition, with respect to WIP level, the experimental results demonstrate that the improvement of 77.91% for the KANBAN system, 40.41% for the CONWIP system, and 69.82% for the DBR system compared to the PUSH system. Since the KANBAN system has the largest impacts on the reduction of the lead-time and WIP level compared to other production systems, this study recommends the KANBAN system as the proper manufacturing system of the target company. This study also shows that the proper size of moving units is four and the priority allocation of bottleneck process methods improves the target company’s WIP and lead-time. Based on the results of this study, the adoption of the KANBAN system will significantly improve the production process of the target company in terms of lead-time and WIP level.

The objective of this paper is to experimentally analyze the combined heat and mass transfer characteristics of LiCl aqueous solution for the plate type dehumidifier with grooves on the plate surface. The solution wettability and flow distribution increase by the grooves on the plate surface. The effects of process air and solution inlet conditions on the dehumidification performance are studied in this study.

N/A To elucidate a possible secondary gastric hypersecretion due to the lack of secretin response after biliary diversion from the duodenum, gastric acid outputs and serum secretin concentrations, basal and in response to feeding, were measured before and after diversion of bile from the duodenum to the jejunum in dogs prepared with Heidenhain pouches. Both 24-hour and postprandial Heidenhain pouch acid outputs increased significantly after biliary diversion compared with the preoperative controls(p<0.01). Increases in serum secretin concentrations caculated as integrated responses after feeding were also greater after biliary diversion compared with the preoperative controls(p<0.01). It is suggested that the changes in serum secretin levels after biliary diversion seem to be the result, rather than the cause, of gastric hypersecretion and if the mechanism of gastric hypersecretion after biliary diversion is considered in view of the loss of gastric inhibitory hormones, some hormones other than secretin should be suspected and studied.
