Objectives: This study was performed to review the research trends in the treatment of Tai Chi on anxiety. Methods: We searched for articles in Pubmed and China National Knowledge Infrastructure (CNKI) from January 2009 to December 2018. The selected studies were evaluated by Jadad Scale. Results: One pre-post comparison study and seven controlled clinical trials were selected. HAMA (Hamilton Rating Scale for Anxiety) and STAI (State Anxiety Inventory) were the most frequently used diagnostic criteria. For outcome measurement, STAI was again the most commo. From Jadad Quality Assessment Scale of 8 articles, the overall quality of the studies was low. Conclusions: According to this study, it seemed that Tai Chi treatment on anxiety disorder is an effective and safe intervention. Therefore, based on this study, more clinical research on diverse forms of treatments of anxiety disorder should be performed in Korean medicine in the near future.

Objective: The purpose of this study was to investigate questions and instructions for internal feedback effects on functional recovery and task performance while chronic stroke patients practised task-specific training. Method: Twenty-four chronic stroke patients were randomly divided into two groups; when patients performed same tasks, one was treated using questions and the other using instructions for internal feedback Both lasted 30 minutes, 5 times a week for 8 weeks. Outcome measures included Erasmus MC Modifications to the Nottingham Sensory Assessment (EmNSA), Measurement Properties of the Motor Evaluation Scale for Upper Extremity in Stroke patients (MESUPES), Chedoke Arm and Hand Activity Inventory (CAHAI), Korean version of Modified Barthel Index (K-MBI). Results: There were no significant differences between the two groups in EmNSA and K-MBI(p>.05). But, in MESUPES and CAHAI, there was significant difference between the two groups(p<.05). Conclusion: In this study, questions for internal feedback during task-specific training are more effective in improving upper extremity motor function and task performance than instructions for internal feedback.

We compared two typical ensemble time scale algorithms; AT1 and Kalman filter. Four commercial atomic clocks composed of two hydrogen masers and two cesium atomic clocks provided measurement data to the algorithms. The allocation of relative weights to the clocks is important to generate a stable ensemble time. A 30 day-average-weight model, which was obtained from the average Allan variance of each clock, was applied to the AT1 algorithm. For the reduced Kalman filter (Kred) algorithm, we gave the same weights to the two hydrogen masers. We also compared the frequency stabilities of the outcome from the algorithms when the frequency offsets and/or the frequency drift offsets estimated by the algorithms were corrected or not corrected by the KRISS-made primary frequency standard, KRISS-F1. We found that the Kred algorithm is more effective to generate a stable ensemble time scale in the long-term, and the algorithm also generates much enhanced short-term stability when the frequency offset is used for the calculation of the Allan deviation instead of the phase offset.

When assessing the radiological consequences of postulated accident scenarios, it is of primary interest to determine the amount of radioactive fission gas accumulated in the fuel rod free volume. The state-of-the-art semi-empirical approach (ANS 5.4-2010) is reviewed and compared with a mechanistic approach to evaluate the release of radioactive fission gases. At the intra-granular level, the diffusion-decay equation is handled by a spectral diffusion algorithm. At the inter-granular level, a mechanistic description of the grain boundary is considered: bubble growth and coalescence are treated as interrelated phenomena, resulting in the grain-boundary venting as the onset for the release from the fuel pellets. The outcome is a kinetic description of the release of radioactive fission gases, of interest when assessing normal and off-normal conditions. We implement the model in SCIANTIX and reproduce the release of short-lived fission gases, during the CONTACT 1 experiments. The results show a satisfactory agreement with the measurement and with the state-of-the-art methodology, demonstrating the model soundness. A second work will follow, providing integral fuel rod analysis by coupling the code SCIANTIX with the thermo-mechanical code TRANSURANUS.

This scoping review was conducted to identify the trends of cost-effectiveness studies on treatment of Korean medicine after rotator cuff surgery and indicators used in those studies. In researching stage, "patients after rotator cuff surgery", "cost-effectiveness evaluation" and "treatment of Korean medicine" were set as the keywords in "Pubmed", "Google scholar" and Korean databases (RISS, OASIS, KCI). There were no studies containing all three keywords, and after searching separately for "cost-effectiveness evaluation" and "treatment of Korean medicine", each 7 studies were reviewed. The indicators used in the study were identified such as study design, characteristics of subjects, outcome measurement and others. This study identified the need for cost-effectiveness evaluation on the treatment of Korean medicine after rotator cuff surgery. We expect that those indicators will be used to implement other studies afterwards.

건설R&D 사업은 1994년에 12억원으로 시작하여 2004년에는 300억원으로 총 1,257억원(총 418건)을 투자하였지만, 과제당 연구비가 약 3억원으로 소형과제 위주로 추진됨으로써, 건설현장에 적용할 수 있으며, 사업화가 가능한 연구결과물은 거의 없었다. 또한 건설R&D 성과측정에 대한 관심이 상대적으로 적었고 그 중요성도 인식하지 못했던 것이 사실이었다. 특히 건설 R&D 성과측정 결과를 비교하기 위한 정형화된 방법론 및 계량화된 측정 자료를 가지고 있지 못해서 연구성과를 기반으로 한 지속적인 연구개발 투자보다는 매년 기술수요조사에 대응하는 형태의 연구개발투자가 이루어졌다. 따라서 본 연구에서는 스타기술 평가를 위한 성과지표들을 선정하기 위해 Balanced Score Card (BSC) 방법론을 응용하여 건설분야 R&D에 맞도록 생산성, 지식축적, 인력양성, 공공복지 4가지로 수정하며 건설R&D 성과분석 방법론을 제안하였다. 이렇게 계량화된 성과자료는 건설 R&D 투자의 근거자료가 되고 그동안 측정하기 어려웠던 건설기술의 가치에 대한 신뢰성을 제고하여 건설R&D 예산을 지속적으로 확보하기 위한 중요한 기본 자료로 활용될 수 있을 것이다.
