This discussion article provides commenting on the sections of the review paper by Ahmad et al. (the authors) concerning consistency limits determinations for peats and peaty soils, drawing on the writer’s experiences regarding the usefulness of liquid limit (LL) and plastic limit (PL) testing/results for these soils in explaining their geotechnical behaviors/properties. From the writer’s experience, despite being regularly specified in geotechnical engineering practice and used in research work, the conventional consistency limits tests generally do not produce physically meaningful results when testing peat soils, especially for more fibrous peats. Hence, the writer does not agree with the authors’ recommendations on consistency limits testing of peats; namely, they recommended that an utmost effort is needed to improve the quality and standard of the thread rolling test and the fall-cone test for consistency limits determinations of highly organic soils such as peat. Rather than grappling with various known inherent shortcomings of consistency limits testing for peats and other highly organic soils, a suggested way forward for assessing the likely geoengineering behavior/properties of these materials points to the routine measurement of a more useful suite of index tests; namely, their natural water content, organic content, fiber content, and humification (decomposition) level. In this discussion, the above aspects are explored in detail, including greater elaboration of the writer’s earlier research work in this area, which was touched on in the authors’ paper.

Purpose: Rehabilitation science programs utilize cognitive and non-cognitive factors to select students who can complete the didacticand clinical portions of the program and pass the licensure exam. Cognitive factors such a prior grade point average and standardizedtest scores are known to be predictive of academic performance, but the relationship of non-cognitive factors and performance is lessclear. The purpose of this systematic review was to explore the relationship of non-cognitive factors to academic and clinical performance in rehabilitation science programs. Methods: A search of 7 databases was conducted using the following eligibility criteria: graduate programs in physical therapy (PT),occupational therapy, speech-language pathology, United States-based programs, measurement of at least 1 non-cognitive factor, measurement of academic and/or clinical performance, and quantitative reporting of results. Articles were screened by title, abstract, andfull text, and data were extracted. Results: After the comprehensive screening, 21 articles were included in the review. Seventy-six percent of studies occurred in PT students. Grit, self-efficacy, emotional intelligence, and stress were the most commonly studied factors. Only self-efficacy, emotional intelligence, and personality traits were examined in clinical and academic contexts. The results were mixed for all non-cognitive factors. Higher grit and self-efficacy tended to be associated with better performance, while stress was generally associated with worse outcomes. Conclusion: No single non-cognitive factor was consistently related to clinical or academic performance in rehabilitation science students. There is insufficient evidence currently to recommend the evaluation of a specific non-cognitive factor for admissions decisions.
Trespass to Airspace: How to Deter North Korea from Its Space Ambitions?
Kelly Kuan Shang (사) 이준국제법연구원 2013 Journal of East Asia and International Law Vol.6 No.1
In deterring North Korea from pursuing its space ambitions, the neighboring States may consider to advance a sovereignty argument that North Korea's overflying rockets have trespassed to their territorial airspace. The current UNSC Resolution-based arguments may not provide adequate deterrence because they are built upon a unilateral interpretation of the UNSC Resolutions and therefore lack legal persuasiveness. Currently, there is seemingly a strong international consensus favoring the demarcation line between airspace and outer space at approximately 100-120 kilometers above the sea level. As the North Korean rockets will likely overflow foreign territories when reaching to this altitude, a trespass claim should therefore have strong legal merits. Moreover, North Korea cannot raise a defense by claiming a right of innocent passage over foreign airspace, because such right does not exist as a customary international law. Even if such right exists, North Korea will be hard to rely on it because its overflying rockets are hardly 'innocent.'
Da Jiang Innovation, DJI: The Future of Possible
Kelly Sze Hiu Chin,Alex Chun Yin Siu,Stanley Yau Kit Ying,Yifan Zhang Academy of Asian Business (AAB) 2017 Academy of Asian Business Review Vol.3 No.2
This paper analyses subjective and objective factors of success of the Chinese drone startup DJI, which has developed from a dormitory workshop to a top global drone manufacturer. Devotion to innovation, attention to marketing and passion of the leaders are highlighted as cornerstones to the success of the company, while structural factors including external economy of scale, rapid growth in demand and pioneering advantage are also analysed. The prospect and challenges of the firms are surveyed and suggestions are also given.

Study Design: A literature review. Purpose: To explore the utility of laminoplasty in combination with instrumented fusion, with a focus on neurological outcomes and changes in kyphotic deformity. Overview of Literature: Management of cervical spondylotic myelopathy (CSM) to reduce morbidity within the neurosurgical population. Methods: A US National Library of Medicine PubMed search was conducted for manuscripts pertaining to cervical laminoplasty and fusion for the management of CSM. Several relevant studies were shortlisted for review, and the bibliographies of the articles were searched for additional references. The search was limited to human studies, English-language literature, and reports on more than one patient. Results: Combined laminoplasty and fusion was found to provide at least comparable, if not superior, neurological outcomes in specific patient populations with CSM. The Japanese Orthopedic Association scores, local kyphosis, and C2–C7 angle have been reviewed in several manuscripts, and improvement in each of these categories was found with laminoplasty and fusion. Conclusions: The treatment of CSM necessitates an individualized approach based on the pathoanatomical variation. Laminoplasty and fusion can be appropriately used for patients with CSM in a setting of local kyphotic deformity, ossification of the posterior longitudinal ligament, associated segmental instability, and the need for strong stabilization.

존 켈리 회장은 7월 12일 경주시 힐튼호텔에서 열린 '원자력 안전 및 해체산업 육성 국제 포럼'에 참석하여 'Perspectives on the Future of Nuclear Power in the United States'를 주제로 특별강연을 했다. 켈리 회장은 강연을 통해 미 행정부의 원자력정책, 미국 원자력산업의 단기 도전 과제, 전력 생산에서의 이산화탄소 감축과 원전 역할, 원전의 지속적인 운영, 미국에서 진행되는 신형 원자로 설계 등을 피력했다. 켈리 회장은 이날 언론과의 인터뷰에서 "한국은 원자력산업 강국인데, 원전 안전성에 대한 과학적인 근거보다 정치적 이슈로 신규 원전을 짓지 않고 수명 연장 대신 조기 폐쇄를 결정한 것은 우려할 사안"이라고 말하고 "원전산업 축소는 장기적으로 기업의 전력 확보가 어려워져 경제적 타격을 입는다. 특히 한국은 원전을 수출하면서 탈원전정책을 펴면 수출에 지장을 받지 않을까 걱정된다."고 밝혔다. 켈리 회장은 MIT 원자력공학박사로 미국 에너지부(DOE) 원자력에너지 기술책임자를 지냈다. 본고는 발표 내용을 정리한 것이다.
