Plastic surgery training worldwide has seen a thorough restructuring over the past decade, with the introduction of formal training curricula and work-based assessment tools. Part of this process has been the introduction of revalidation and a greater use of simulation in training delivery. Simulation is an increasingly important tool for educators because it provides a way to reduce risks to both trainees and patients, whilst facilitating improved technical proficiency. Current microsurgery training interventions are often predicated on theories of skill acquisition and development that follow a 'practice makes perfect' model. Given the changing landscape of surgical training and advances in educational theories related to skill development, research is needed to assess the potential benefits of alternative models, particularly cross-training, a model now widely used in non-medical areas with significant benefits. Furthermore, with the proliferation of microsurgery training interventions and therefore diversity in length, cost, content and models used, appropriate standardisation will be an important factor to ensure that courses deliver consistent and effective training that achieves appropriate levels of competency. Key research requirements should be gathered and used in directing further research in these areas to achieve on-going improvement of microsurgery training.

The purpose of this paper is to suggest the development of the Guidelines on VTS English language competency test, according to IALA Guideline 1132 - VTS Voice Communications and Phraseology. As the foundation for improving VTSOs' communication capabilities throughout their career lifecycle in terms of training, accreditation, and revalidation, a development of a VTS-specific language testing system with explicit language testing evaluation criteria becomes more critical. With the aim of facilitating the discussion, a range of suggestions to be considered in the development of Guidelines on the VTS English competency test are made

심해에서의 유전개발이 활성화되면서 이러한 개발에 필수적인 장비인 동적위치제어시스템 (Dynamic Positioning System, DPS)을 설치한 선박 또는 해양구조물의 수요도 폭발적으로 증가하고 있으며, 이에 따라 DPS 운영에 필수적인 DPO (Dynamic Positioning Operator) 자격증을 취득하고자 하는 지원자도 매년 급속하게 증가하고 있다. 그러나 DPO 교육훈련과정은 강제요건이 아니며, 따라서 엄정한 자격증명 및 검증이 어려운 실정이다. 특히 매년 2000건 이상의 신규면허를 심사하고 발급하는 것은 물론 기존 면허자에 대한 재검증 절차도 수행하여야 하는 현재의 상황으로 볼 때 효율적인 DPO 양성을 기대하기는 어려운 실정이다. 이 연구에서는 보다 이러한 문제점을 개선하여 보다 더 효율적이면서도 엄정한 DPO 양성을 위한 제도개선을 제안한다.

The genus Sinopoda (Araneae, Sparassidae) from Korea are taxonomically reviewed. As a result, Sinopoda aureola is removed from the synonymy of Sinopoda stellatops and treated as a valid species. In addition, two new species, Sinopoda biguttata sp. nov. and Sinopoda nigrobrunnea sp. nov. are described with accompanying photographs. The new species, S. biguttata sp. nov., can be distinguished from other congeners by the combination of following characteristics: a pair of large ivory patterns near posterior muscle sigilla on opisthosoma; relatively small internal genitalia and long, distally bifurcated fertilization duct. The new species, S. nigrobrunnea sp. nov., can be distinguished from other congeners by the combination of following characteristics: lateral edge of epigyne angled; edge of epigynal pocket linear; glandular appendages perpendicularly directed then curved posteriorly.

Employability is a critical issue in construction education. Employability is more than students obtaining employment upon graduation. The concept is far more ranging, and should encompass enabling students to acquire the knowledge, personal and professional skills and encouraging attitudes that will support their future development and employment. This paper describes two case studies relating to how the true concept of employability can be incorporated into the construction higher education curriculum. Case study 1 was a collaborative venture with contributions from a higher education provider, employers, students and a professional body (Association of Building Engineers). It outlines the whole process from course inception through to graduation and feedback. Thus it presents a valid model for other higher education providers of construction courses to adapt or adopt. Case study 2 outlines how the opportunity of a degree programme revalidation process was utilized to introduce modules which would enhance students' employability on graduation.

A new intelligent adaptive control scheme was proposed that combines observer disturbance-based adaptive control and fuzzy adaptive control for a composite structure with a mass-adjustable damper. The most important advantage is that the control structures do not need to know the uncertainty limits and the interference effect is eliminated. Three adjustable parameters in LMI are used to control the gain of the 2D fuzzy control. Binary performance indices with weighted matrices are constructed to separately evaluate validation and training performance using the revalidation learning function. Determining the appropriate weight matrix balances control and learning efficiency and prevents large gains in control. It is proved that the stability of the control system can be ensured by a linear matrix theory of equality based on Lyapunov's theory. Simulation results show that the multilevel simulation approach combines accuracy with high computational efficiency. The M-TMD system, by slightly reducing critical joint load amplitudes, can significantly improve the overall response of an uncontrolled structure.

The COVID-19 pandemic had substantial negative impacts and caused several disruptions to the global supply chain of the shipping industry. The key challenges identified in terms of maritime manpower are the Certificates of Competency (CoC) or the expiration and/or failure to complete refresher and/or revalidation courses, which directly hinder employment retention and lost opportunities at sea. To tackle this issue directly and swiftly, the creation of the APEC SEN Distance Learning Platform was suggested and approved by APEC as part of an official project. This paper introduces the APEC-wide accessible distance learning platform with the following key topics: the organisation and operation of the platform, the themes and content to be prioritised, the process of education, training, certification, and the ways to promote accreditation, mutual recognition on CoC, education and training videos by taking collaborative actions, and the development of content.

The purpose of this study was to revalidate the 'Hospital Violence Attitude Scale-18 (HVAS-18) in clinical nurses'. 150 clinical nurses from three general hospitals in two cities participated in this study. Data were collected from March to April in 2017. The collected data were analyzed using factor analysis, Pearson correlation coefficients, and Cronbach's alpha. The final HVAS-14 consisted of fourteen items and four factors emerged, which explained 74.1% of the total variance. These four factors were labeled: Factor 1 (3 items) 'awareness' which explained 20.3%; Factor 2 (4 items) 'response' which explained 20.2%; Factor 3 (3 items) 'reaction' which explained 15.5%; and Factor 4 (4 items) 'result' which explained 15.4%. The internal consistency and intraclass correlation coefficient (ICC), as measured by Cronbach's alpha, were both .87, and the reliability of the subscales ranged from .78 to .86. The results of this study indicate that HVAS-14 is a useful, reliable and valid instrument to measure the hospital violence attitude of clinical nurses.

Process Hazard Analysis(PHA) have been performed for a risk management of process (petrochemical) industry for nearly 50 years. There are many PHA methods for application in the process industry, Hazop Study method has been recognized as a good method used typically in most of phase of process plant. And also there was inconvenient opinion that Hazop Study is too resource (man power, time etc.) consuming comparing its result performance (a quality of recommendations) for a good operating and existing plant. In this study, two types of PHA method - checklist and K-PSR - were performed respectively for a new para-xylene(PX)plant and 30 year old PX plant. Past history and experience of incident, operation, maintenance and so on are very important in PHA by those two methods. The higher effectiveness were realized in PHA by a checklist and K-PSR Method than prior Hazop study. And also some suggestions including PHA cycle determination, RBPS application, Follow-up plan of PHA result etc. were proposed about PHA improvement measures for a best risk management.

The poisson's ratio was obtained from the effective vertical stress and horizontal stress of consolidation-undrained test. It was analyzed void ratio verse poisson's ratio. At the result, the effective friction angle was increase with relative density increased, was decreased the poisson's ratio. The empirical equation of void ratio and poisson's ratio was showed very high correlation r²=0.846. The empirical equation was showed that the smaller the void ratio in the fine grained soil than granular soil. In the case of 0.85 times the correlation analysis equation of granular and fine grained soil, the experimental results were shown very similarly. In especially, the poisson's ratio prediction results was shown within 5% of the error range, was revalidation 0.85 times the correlation analysis equation using the void ratio. In this study, correlation analysis equation of the granular and fine grained soil was more reliability of the poisson's ratio prediction results apply to the void ratio than dry unit weight.
