  • A very simple synthetic route of a novel SATE prodrug type of 6'-fluoro-6'-methyl-5'-noradeonosine carbocyclic nucleoside phosphonic acid is described. The key fluorinated alcohol intermediate 7 was prepared from the epoxide intermediate 6a via selective ring-opening of epoxide. Coupling of 7 with $N^6$-bis-Boc-adenine under a Mitsunobu reaction followed by phosphonation and deprotection afforded the carbocyclic phosphonic acid. The chemical stability of the bis(SATE) derivative 13 was measured at neutral (pH 7.2) and slightly acidic (Milli-Q water, pH 5.5) pH. The antiviral activity test of the SATE prodrug 13 and its parent nucleoside phosphonic acid 11 were evaluated against HIV-1.

  • The purpose of this thesis is to analyze the success factors of ERP system in corporations and to know what is different in the factors depending on organizational culture and size. Considering there are various results from introduction of the same information technology(IT), it is implied that organizational characteristics make a difference. In this thesis we did factor analysis and multiple regression about the factors based on the previous studies and analyzed the priorities depending on organizational culture and size. The results show that mechanistic organization has key success factors of work process change, project team abilities, and determination of CEO while organic organization has those of work process change and project team abilities. Plus bigger sized organization has success factors of work process change, project team abilities, and determination of CEO while small sized organization has those of work process change and project team abilities.

  • Novel 4'-ethyl-5'-norcarbocyclic adenosine phosphonic acid analogues were synthesized from propionaldehyde 5 through a de novo acyclic synthetic route using reiterative Grignard additions and ring-closing metathesis (RCM) as key reactions. The synthesized nucleoside phosphonic acids analogues 17, 18, 19, and 21 were subjected to antiviral screening against human immunodeficiency virus.

  • MMI system for strip caster 2 is described. It has been developed as a PC-based MMI system whose data is collected from the VME-based control system by ETHERNET. MMI elements that mimic the caster and its utilities are designed by using commercial program. In order to implement the UDP/IP communication in MMI, UDP/IP manager program with DDE that is a intercommunication protocol in MS-window is developed and connected with MMI mimics. Operator commands in MMI system are carried out immediately in VME system and the responses are displayed on MMI system. The developed MMI system has been proven to be convenient and stable through the operation of the past 5 years.

  • This report describes the echocardiographic features of an indirect Gerbode defect in a young cat. Echocardiography revealed high-velocity, turbulent systolic flow directed from left ventricle to right ventricle through a ventricular septal defect. The flow immediately entered the right atrium through a tricuspid septal leaflet. The indirect-type Gerbode defect was confirmed through necropsy. When a high-velocity turbulent flow in the RA without pulmonary hypertension is observed on echocardiography, Gerbode defect should be considered.

  • Significant decisions are made by the project team during the early planning phase of capital facility project developments. The preproject planning phase begins after a decision is made to proceed with a project concept and continues until the detail design stage. Many of the industry practitioners and researchers have recognized the importance of preproject planning and that inadequate early planning is one of the key factors affecting project success. Nevertheless, the preproject planning practices vary significantly for the construction industry in Taiwan and the quality of preproject planning relies heavily on individual project team's experience. This research sets out to benchmark the preproject planning practice for the building construction industry in Taiwan. From late 2007 to early 2010, the researchers collected information from a total of 92 building construction projects using questionnaire survey. The analysis results show that the surveyed projects with better preproject planning have better cost and schedule performances on average. It is recommended that project team spend more efforts in the preproject planning stage to have a better chance of achieving project success.

  • 이 연구의 목적은 팀 기반 프로젝트 학습에서 학습성과에 영향을 미치는 팀효능감과 태만의 효과를 살펴보는 것이다. 이를 위해 H 대학교 사회복지학과에서 팀 기반 프로젝트 학습으로 진행된 수업 사례를 분석하였다. 2019년에 개설된 전공수업에 참여한 58명의 대학생을 대상으로 자료를 수집하고 위계적 회귀분석으로 팀효능감과 지각된 태만이 학습성과에 미치는 영향과 두 변인의 상호작용효과를 규명하였다. 분석결과, 첫째, 팀효능감은 학습성과에 정적 영향을 미쳤다. 둘째, 지각된 태만은 개인의 학습성과에 통계적으로 유의한 영향을 미치지 않았다. 셋째, 팀효능감과 지각된 태만의 상호작용효과는 학습성과에 유의한 영향을 미치며, 지각된 태만이 학습성과에 미치는 부정적 영향을 팀효능감이 감소시키는 것으로 나타났다. 연구결과에 기반하여 팀 기반 프로젝트 학습의 학습성과를 높이기 위한 방안에 대해 논의하였다.

  • The purpose of this study is to develop a teaching-learning model of convergence project based on team teaching. Based on development research methodology which explored a university case, the teaching-learning model was developed including three phases such as preparation, planning, and implementation & evaluation. The preparation phase has three steps as follows: to organize team teaching faculty; to develop convergence projects cooperated by industry and university; and to design instructions based on supporting convergence projects. The last step of preparation phase consists of five design activities of: (1) instructions and teaching contents; (2) communication channel among faculty members; (3) feedback system on students' performance; (4) tools to support learners' activity; and (5) evaluation system. The planning phase has two steps to analyze learners and to introduce and modify instruction and themes of convergence projects. The implementation & evaluation phase includes five steps as bellow: (1) to organize project teams and match teams with faculty members; (2) to do team building and assign duties to students of a team; (3) to provide instruction and consulting to teams; (4) to help teams to conduct projects through creative problem solving; and (5) to design mid-term/final presentation and evaluation. Lastly, the research implications and limitations were discussed for future studies.
