Conor James Craig Gouk,Ryan Mark Shulman,Craig Buchan,Michael John Evan Thomas,Fraser James Taylor 대한정형외과학회 2019 Clinics in Orthopedic Surgery Vol.11 No.2

Background: Massive retracted rotator cuff tears represent a therapeutic dilemma, particularly in the young and middle-aged patients who are not appropriate for a reverse total shoulder replacement. Interposition grafting using human dermal allograft offers an alternative treatment. Methods: A retrospective review of all patients who underwent interposition grafting using human dermal allograft between December 2013 and May 2015 for massive rotator cuff tears at our tertiary referral center was performed. Preoperative and 6 month postoperative magnetic resonance imaging (MRI) assessments were performed in all patients, with postoperative graft integrity being the primary outcome measure. Clinical evaluation was performed using the Oxford shoulder score, Constant score, and Disabilities of the Arm, Shoulder and Hand (DASH) score. Results: The mean age at the time of follow-up was 54 years. On MRI, 84% of grafts were seen to have failed at 6 months. Strength was grossly reduced on the operative side when supraspinatus and subscapularis were tested; despite this, Constant score (mean, 48.2) was comparable to that in the previous reports. DASH and Oxford scores were a mean of 24.94 and 37.16, respectively. Conclusions: Based on these results, in particular the MRI findings, we cannot advocate the use of dermal allograft as an interposition graft for the repair of massive rotator cuff tears.

Approaching Recycling of ELVs and E-waste from a Regional Perspective in Asia-Pacific: An Overview of Key Project Work and Cooperation

( Craig Boljkovac ) 한국폐기물자원순환학회(구 한국폐기물학회) 2019 ISSE 초록집 Vol.2019 No.-

The Asia-Pacific Region is one of the most important regions for both recycling of ELVs and e-waste. Through a number of cooperative mechanisms, including Regional Centers for the Basel Convention (including at Tsinghua University in China); Tripartite Environment Ministers Meetings among China, Japan and Republic of Korea; and other forums and organizations, progress at both the policy and practical levels is being made. Nevertheless, significant challenges remain in many countries, including: a lack of coherent national legislation, policies and enforcement; a lack of technical know-how (including latest technologies and techniques for recycling); lack of resources and the general low priority recycling has on the policy agendas of many countries. Conversely, there is growing recognition of the value of the outputs of ELV and e-waste recycling - including some phenomenal success stories in the region. With China’s Belt and Road Initiative and given China’s recent waste import ban, a greater focus on investment in recycling of ELVs and e-waste is taking place, with some initial success stories. In the meantime, continued projects focusing on training and capacity building for national and local government officials and the private and informal sectors are ongoing, leading to greater awareness and progress on this issue. Progress on emerging issues (such as recycling of solar panels and electric batteries), where little, if any focus is being placed by governments at present, can also be strengthened through cooperation within the region. At the international level, there is, concurrent with the recent 30th anniversary of the Basel Convention, growing recognition that the future of waste management lies with the Asia-Pacific Region. Increased technology transfer, cooperation between experienced companies and governments in other regions (e.g. Europe and North America), and initiatives through the United Nations and other international organizations will likely serve to assist in solving the significant challenges ELVs and e-waste recycling pose for the region.

China as the Leader of the Small and Weak: The "Ruoxiao" Nations and Guomindang Nationalism

Craig A. Smith 고려대학교 민족문화연구원 2017 Cross-Currents Vol.0 No.24

Frustrated with the “white imperialism” of the League of Nations and the “red imperialism” of the Third Communist International, a number of Chinese intellectuals began discussing possibilities for a third option during the interwar years. Turning away from liberalism and Marxism, they examined Sun Yat-sen’s Three Principles of the People and began working to promote his Principle of Nationalism as a concept that focused on the ruoxiao (weak and small nations) and could liberate people around the world that were suffering under imperialism. This discourse often centered on the possibility of creating a new form of “International,” the International of Nations, which would unite the oppressed nations of the world in opposition to the imperialist nations, rather than divide nations along class lines, as Chinese critics perceived the Comintern to do. This article examines Chinese intellectual discussions of a China-centered “International” by a variety of writers, including Dai Jitao and Hu Hanmin, from 1925 to 1937. The author shows that, although this discourse on a China-centered “International of Nations” influenced intellectuals’ perceptions of China’s position and responsibility in the world, it was consumed and invalidated by Japanese imperialism, as the Japanese Empire employed a similar discourse of pan-Asianism to justify militarism in the 1930s and 1940s.

The first report of the buckled thyroid cartilage in a human cadaver

Craig Ballard,Joe Iwanaga,Eva Maranillo,Jose Sanudo,Aaron S. Dumont,R. Shane Tubbs 대한해부학회 2023 Anatomy & Cell Biology Vol.56 No.2

We present the first case of buckled thyroid cartilage identified in a human cadaver. This rare anatomical variant,in patients, often produces dysphonia and is a potential source for diagnostic confusion. In the cadaveric case described, the laryngeal prominence is deviated to the left without deviation of the internal structures of the larynx, such as vocal folds and vocalis muscles. The medical history of the patient is not known. Finally, a review of current literature on the buckled thyroid cartilage is presented. Such a case represents a rare opportunity to visualize this deformity via anatomical dissection.

Negotiation progress for an international agreement on ending plastic pollution

( Craig Boljkovac ) 한국폐기물자원순환학회 2022 ISSE 초록집 Vol.2022 No.-

Plastics Pollution is a growing environmental and health related problem. Therefore, the UN Environment Programme decided at a recent UN Environment Assembly (UNEA 5.2) in Nairobi, Kenya, to commence negotiations among countries for a global, legally binding instrument to address plastics. The first Intergovernmental Negotiating Committee meeting (INC-1) will take place in Uruguay in late-2022. Plastics production, and the pollution that results is increasing rapidly worldwide. Many individual governments have taken decisive action to address such pollution, including the phase-out, where possible, of single-use plastics, but, to-date, a comprehensive global effort is in its early stages. The exception to this is the 2018 amendments to the Basel Convention addressing key categories of plastics waste in the international waste trade. Plastics pollution is ubiquitous - waterways, soils, and even the air we breathe have traces of microplastics - and it is said there is not a square meter of the sea floor worldwide that does not have plastics/microplastics present. The famous Pacific waste gyre contains a tremendous volume of plastic materials. Such “legacy issues” (in addition to the continued production and management of plastics) will also need to be addressed under the convention. With the upcoming negotiations for the legally binding instrument looming, there are detailed discussions ongoing at the international level regarding the scope and future effectiveness of the treaty. Some government want only “lightly” legally binding components to the treaty (e.g. a National Action Plan to be reported by Parties on a regular basis), with the remainder of the convention only having voluntary aspects; while other countries would like the entire life cycle of plastics production, use, and disposal to be addressed in a legally binding manner, perhaps under the chapeau of a global circular economy. China is a key player in these discussions, and was key in the process to amend the Basel Convention. Countries like China,, EU and US will be key to determining the final shape and form of the convention.

Review of Social and Organizational Issues in Health Information Technology

Craig E. Kuziemsky 대한의료정보학회 2015 Healthcare Informatics Research Vol.21 No.3

Objectives: This paper reviews organizational and social issues (OSIs) in health information technology (HIT). Methods: A review and synthesis of the literature on OSIs in HIT was conducted. Results: Five overarching themes with respect to OSIs in HIT were identified and discussed: scope and frameworks for defining OSIs in HIT, context matters, process immaturity and complexity, trade-offs will happen and need to be discussed openly, and means of studying OSIs in HIT. Conclusions: There is a wide body of literature that provides insight into OSIs in HIT, even if many of the studies are not explicitly labelled as such. The two biggest research needs are more explicit and theoretical studies of OSI in HITs and more research on integrating micro and macro perspectives of HIT use in organizations.

The artificial urinary sphincter and male sling for postprostatectomy incontinence: Which patient should get which procedure?

Craig V. Comiter,Amy D. Dobberfuhl 대한비뇨의학회 2016 Investigative and Clinical Urology Vol.57 No.1

Surgery is the most efficacious treatment for postprostatectomy incontinence. The ideal surgical approach depends on a variety of patient factors including history of prior incontinence surgery or radiation treatment, bladder contractility, severity of leakage, and patient expectations. Most patients choose to avoid a mechanical device, opting for the male sling over the artificial urinary sphincter. The modern male sling has continued to evolve with respect to device design and surgical technique. Various types of slings address sphincteric incompetence via different mechanisms of action. The recommended surgery, however, must be individualized to the patient based on degree of incontinence, detrusor contractility, and urethral compliance. A thorough urodynamic evaluation is indicated for the majority of patients, and the recommendation for an artificial urinary sphincter, a transobturator sling, or a quadratic sling will depend on urodynamic findings and the patient's particular preference. As advancements in this field evolve, and our understanding of the pathophysiology of incontinence and mechanisms of various devices improves, we expect to see continued evolution in device design.

Tackling Geoenvironmental Problems in the Unsaturated Zone: Principles and Practice

( Craig Benson ) 대한지질공학회 2019 대한지질공학회 학술발표회논문집 Vol.2019 No.2

Many geoenvironmental problems involve processes in the vadose zone, where flow and transport are complex, and rapid changes in conditions occur spatially and temporally. Historically this complexity made predictions highly uncertain, if not impossible. Advances over the last two decades have led to substantial improvements in characterization of hydraulic and transport properties in the vadose zone and predictions regarding flow and transport, permitting practical design and analysis with relative ease. New standard methods have made extremely tedious and complex measurements more practical and reliable, and new software packages have made predictions expedient. Modern methods used for vadose zone characterization are described, predictive models are presented, and examples are shared where unsaturated hydraulic properties and variably saturated flow modeling have been used to design and evaluate geoenvironmental problems in the vadose zone. The examples include comparisons with field data, demonstrating the strengths of current techniques as well areas in need of additional development.
