Bare metal stents which were used to treat coronary artery disease have several biochemical problems. Polymerbased drug-eluting stents (DES) have opened up a new paradigm in the treatment of in-stent restenosis. Many studies and research programmes have proved that DES can prevent restenosis. In our study, paclitaxel-loaded poly (lactic-co-glycolic acid) (PLGA) nanoparticles have been deposited along the three dimensional scaffold of coronary stents by a method using self-assembling properties of colloidal particles. We found that the nanoparticles were deposited uniformly and closely packed. The amount of paclitaxel was easily controlled by the drug content of the nanoparticles and the deposition count.

In the past decade, various experimental programmes were undertaken to address the lack of information on the interaction between steel coupling beams and reinforced concrete shear wall in a hybrid coupled shear wall system. In this paper, the seismic performance of steel coupling beam-wall connections in a hybrid coupled shear wall system is examined through results of an experimental research programme where three 2/3-scale specimens were tested under cyclic loading. The test variables included the reinforcement details that confer a ductile behaviour on the steel coupling beam-wall connection, i.e., the face bearing plates and the horizontal ties in the panel region of steel coupling beam-wall connections. Panel shear strength reflects enhancement achieved through mobilization of the reinforced concrete panel using face bearing plates and/or horizontal ties in the panel region of steel coupling beam-wall connections.

Solar Photovoltaics (SPV) In India has become an important renewable source of energy particularly for rural and remote areas. The vastness of the country and the requirements of electricity in far-flung villages makes SPV very attractive, with inherent technological advantages providing additional boost. This has been recognized very early by Govt. Of India and Ministry of Non-Conventional Sources of Energy (MNES) has been entrusted with promoting SPV usage in the country. Rural electrification through SPV systems is one of the programmes which is expected to provide fillip to PV industry in the country. PV Industry in India is very well established with capability of solar cell fabrication and module fabrication as well as Balance of System design and fabrication. There several R&D groups in the academic institutions who are involved in improving solar cells efficiency, thin film solar cells and PV instrumentation. Thus, India provides a ready market for large scale utilization of solar energy through SPV technology.

Issues and themes concerned with nuclear power plant uprating are examined. Attention is brought to the fact that many candidate nuclear power plants for uprating have anyway been operated below their rated power for a significant part of their operating life. The key issues remain safety and reliability in operation at all times, irrespective of the nuclear power plant's chronological or design age or power rating. The effects of power uprates are discussed in terms of material aspects and expected demands on the systems, structures and components. The impact on operation and maintenance methods is indicated in terms of changes to the ageing surveillance programmes. Attention is brought to the necessity checking or revising operator actions after power up-rating has been implemented.

Hepatitis C infection is responsible for high morbidity and mortality rates globally as well as for significant indirect costs. The disease burden caused by the hepatitis C virus (HCV) is comparable to the one caused by human immunodeficiency virus or tuberculosis. Today, simple detection methods, highly effective and easy to administer therapies and efficient preventative measures are available to combat hepatitis C. Nevertheless, in most countries around the world, the World Health Organization target of eliminating this infectious disease and its consequences by 2030 are not being met. Significant gaps in care for hepatitis C sufferers still exist, the shortcomings ranging from education and treatment to aftercare. Hepatitis C infection was and still is not on the radar of most politicians and health authorities. National programmes and strategies to combat the disease exist or are being developed in many countries. However, for these to be implemented efficiently and successfully, clear political commitment, strong civil society actors, well-functioning public health structures and the relevant support from global donors are needed.

When newcomer countries consider a nuclear power programme, it is recognized that the most important organizations are the Nuclear Energy Programme Implementing Organization (NEPIO), the regulator, and an operating organization. Concerning the number of construction delays these days, one of the essential organizations is an Authorized Inspection Agency (AIA). According to World Nuclear Industry Status Report, all of the reactors under construction in eight out of the thirteen countries have experienced delays. Globally, the Flamanville 3 project and Sanmen Unit 1 are 6.5 years and 5 years late respectively. One of the major reasons of delay is due to inappropriate manufacturing and inspection on safety class components. The recommendations are made to develop such an organization: (i) find existing inspection organizations in relevant industries, (ii) contract with expatriates who have experience on nuclear inspection, (iii) develop a legislative framework to authorize the inspection organization with enforcement, (iv) include a contract clause in the BIS for developing the AIA, (v) hold training programmes from vendor country, (vi) during manufacturing and construction, domestic AIA shall be involved.

By using the Blackboard (BB) system in the education sector, the educational process for both academics and students is facilitated. Two data resources were used to evaluate the use of the BB system by students of Umm Al-Qura University: statistical reports issued by the university and an online questionnaire. A total of 989 students from all colleges and different programmes provided by the university responded to the questionnaire survey. According to our findings, most students did not use the BB before the pandemic. Therefore, the sudden conversion to the BB system required intensive training courses. After the data analysis, the relationship between the use of the BB system before the pandemic and the problems students faced during the lockdown was revealed. The most critical issues raised by the respondents were: (1) "The voice of the lecturer went on and off during BB collaborate class", (2) "internet connection of the lecturer went on and off during BB collaborate class" and (3) "High possibility of IT problems during exams".

Foreign learners are not focusing on "적" grammar. Therefore, the lack of materials on "적" is the reason that foreign learners use "적" in real life. In particular, when teaching the Chinese-dependent noun "적", there are some problems in making the Chinese equivalent of "적". more accurately understood by Koreans. In addition, when using grammar through analyzing the grammatical conjunction centered on "적" and the corresponding expression of Chinese, the main reason for the error is that there is no common concept and form in the mother tongue, so there is no consciousness. Therefore, it is difficult for learners to learn similar expressions that are not in Chinese or Korean. Therefore, this study aims to improve specific educational programs for Korean learners and Korean Chinese learners in terms of the time system and the corresponding performance of Chinese grammar and Chinese characters based on the previous version of "적".

Automation and robotic technology (ART) has been successfully applied in the manufacturing and allied industries to achieve on-time delivery of quality products at increasingly reduced costs. Meeting time, quality and cost targets still remains a big challenge in the global construction industry with prevalence of time and cost overruns. Application of ART in the construction industry could contribute to significant improvement in the efficient and effective delivery of projects to meet and exceed client expectations. However, the uptake of ART is still low in the construction industry. This study investigates the various ways in which ART could be applied to improve construction project delivery, potential areas of applications, and constraints to the uptake of the technology in the construction industry. Recommendations are made for improving the uptake of ART in the construction industry.
