  • 1991년 Davis 가 '정보기술수용모형(TAM, Technology Acceptance Model)'을 제시하여 조직의 정보통신기술 도입이 이것을 사용하는 사용자의 편이성과 기술 도입에 따른 업무의 효용성 및 효과의 정도에 따라 결정되어 진다는 정보화 추진의 이론적 배경을 제공한 이래로, 최근에는 인터넷, 전자우편, 전자문서교환, 그룹웨어 등의 급격한 기술 발전이 진행되면서 공공기관 및 일반 기업의 업무 조직에 많은 변화를 가져오고 있다. 하지만 정보기술의 순기능과 함께 정보기술의 발전은 업무 조직에게 다양한 혜택을 가져다주었으나, 치명적인 역기능도 부가적으로 발생하게 되었다. 통합적인 업무환경에 따라 비 권한자가 정보를 조회하거나 중요 정보의 전산화로 인해 정보관리가 한층 어려워졌으며, 통신 기술의 발달로 인하여 외부로부터의 해킹이나, 내부자에 의한 정보유출이 용이해졌다. 본 연구에서는 조직에서 취급하는 기밀문서의 전자적 처리를 위한 보안 규정과 지침개선안을 마련하여 기밀문서의 세부적 절차 및 구현 방법을 개발하고자 한다.

  • Technology transfer (TT) has been defined as the shared responsibility between the source and the destination for ensuring that technology is accepted and at least understood by someone with the knowledge and resources to apply and/or use the technology. The adoption of TT in construction industries is necessary for economic growth to occur in developing countries such as Thailand. This process should provide numerous benefits for the host sector in areas such as increased productivity, enhancement of product quality, cost savings, improvements in market share and entry to new markets. However, there are many factors, which may impact on the TT process and its subsequent outcomes for Thai construction firms and individuals, including, the transfer environment, learning environment, transferor characteristics and transferee characteristics. The performance and interaction of these enablers will influence the degree of value added to the local construction sectors in areas such as economic advancement, knowledge advancement and project performance. This paper presents a conceptual framework for international TT that accommodates the numerous factors believed to impact on the processes effectiveness. Through a Pilot Study, where 27 industry professionals from Thailand were interviewed, the significant factors which impact on the TT process have been identified along with the strength of interrelationship between individual and groups of factors. Future research seeks to target a greater sample of respondents with the view to validate the conceptual model and apply it on a number of large Thai projects where international TT was incorporated into the project agreement.

  • Purpose: Clinical study to evaluate the efficacy and the safety of various surgical treatments in snoring and obstructive sleep apnea. Methods and materials: We performed surgical treatments such as radiofrequency ablation, uvulopalatopharyngoplasty(UPPP) with tonsillectomy, uvulopalatopharyngoplasty with advancement genioplasty, orthognathic surgery(maxillomandibluar advancement), distraction osteogenesis device insertion. Diagnosis was performed with clinical examination, polysomnography, lateral cephalometric and computed tomography. 62(M : F = 45 : 17, mean age 41.5, mean follow-up 4 weeks) patients underwent radiofrequency ablation and 7 (M : F = 5 : 2, mean age 38.9, mean follow-up 19months)patients experienced uvulopalatopharyngoplasty with tonsillectomy. Uvulopalatophayngoplasty with advancement genioplasty was performed for 3 (M : F = 2: 1, mean age 30.2, mean follow-up 14 months)patients. The last 3(M : F = 2 : 1, mean age 21.5, mean follow-up 24 months)patients was treated with orthognathic surgery including distraction device insertion. The results was evaluated by questionnaires, polysomnography, investigation of complications. Results: Of the patients treated with radiofrequency ablation, 95% reported improvement of their symptom. 100% improvement was reported in patients treated with UPPP with tonsillectomy and UPPP with advancement genioplasty. The two of three patients who underwent orthognathic surgery showed the satisfactory of treatments. Dryness of mouth was the most common complication during short period in radiofrequency ablation and UPPP with tonsillectomy. Relapse complication was not found in any surgical treatments. Conclusion: Treatment for snoring and OSA is determined by severity degree of the physiologic derangements, predominant type of apnea and obstructive site. Accuracy diagnosis should be performed prior to treatment for satisfactory treatment result. This study demonstrates feasibility, safety and efficacy of surgical treatments in snoring and OSA.

  • With the advancement of the industry such as information technology, residential facilities has been consistently achieved high standard. Ubiquitous system has been introduced in apartments nowadays, and it will be general facilities in the near future. However elderly people is not generally accustomed to ubiquitous or internet environment, so degree of ubiquitous system usage is able to be less than young people. This study aims to grasp the relative importance of ubiquitous environment, and offer materials to realize residential environment's improvement of silver towns under investigation through a questionnaire survey. Skin recognition system was most preferred among various functions. Energy management system, protection system of solitude elderly person and security system by CCTV was also preferred at a high rate. Housework part such as cooking aid, height control of sink and basin etc., was not less important system relatively.

  • This study presents a novel safe landing algorithm for urban drone deliveries. The rapid advancement of drone technology has given rise to various delivery services for everyday necessities and emergency relief efforts. However, the reliability of drone delivery technology is still insufficient for application in urban environments. The proposed approach uses the "landing angle control" method to allow the drone to land vertically and a rapidly exploring random tree-based collision avoidance algorithm to generate safe and efficient vertical landing paths for drones while avoiding common urban obstacles like trees, street lights, utility poles, and wires; these methods allow for precise and reliable urban drone delivery. We verified the approach within a Gazebo simulation operated through ROS using a six-degree-of-freedom drone model and sensors with similar specifications to actual models. The performance of the algorithms was tested in various scenarios by comparing it with that of stateof-the-art 3D path planning algorithms.
