Implementation factors and performance of the voluntary agreement(VA) for energy-efficiency management in South Korea - Focusing on the regulatory response and policy learning of the VA facilities -

In terms of power and energy consumption, DRAMs play a key role in a modern server system as well as processors. Although power-aware scheduling is based on the proportion of energy between DRAM and other components, when running memory-intensive applications, the energy consumption of the whole server system will be significantly affected by the non-energy proportion of DRAM. Furthermore, modern servers usually use NUMA architecture to replace the original SMP architecture to increase its memory bandwidth. It is of great significance to study the energy efficiency of these two different memory architectures. Therefore, in order to explore the power consumption characteristics of servers under memory-intensive workload, this paper evaluates the power consumption and performance of memory-intensive applications in different generations of real rack servers. Through analysis, we find that: (1) Workload intensity and concurrent execution threads affects server power consumption, but a fully utilized memory system may not necessarily bring good energy efficiency indicators. (2) Even if the memory system is not fully utilized, the memory capacity of each processor core has a significant impact on application performance and server power consumption. (3) When running memory-intensive applications, memory utilization is not always a good indicator of server power consumption. (4) The reasonable use of the NUMA architecture will improve the memory energy efficiency significantly. The experimental results show that reasonable use of NUMA architecture can improve memory efficiency by 16% compared with SMP architecture, while unreasonable use of NUMA architecture reduces memory efficiency by 13%. The findings we present in this paper provide useful insights and guidance for system designers and data center operators to help them in energy-efficiency-aware job scheduling and energy conservation.

Abstract While the Antarctic Treaty System intended to keep Antarctica an area of international cooperation and science free from militarisation and international conflict, the region has not been completely shielded from global power transitions, such as decolonisation and the end of the Cold War. Presently, emerging countries from Asia are increasingly willing to invest in polar infrastructure and science on the back of their growing influence in world politics. South Korea has also invested heavily in its Antarctic infrastructure and capabilities recently and has been identified as an actor with economic and political interests that are potentially challenging for the existing Antarctic order. This article first assesses the extent and performance of the growing bilateral cooperation between South Korea and one of its closest partners, New Zealand, a country with strong vested interests in the status quo order. How did the cooperation develop between these two actors with ostensibly diverging interests? This article finds that what may have been a friction–laden relationship, actually developed into a win-win partnership for both countries. The article then moves on to offer an explanation for how this productive relationship was made possible by utilising a mutual socialisation approach that explores socio-structural processes around status accommodation.

Implementation Factors

The purpose of the study was to examine how project implementation factors (provision of work-space facility, entrepreneurship training and promotion of products) influence the performance of Jua-kali Empowerment Programmes (JEP) in Nairobi County, Kenya. The study was rooted upon theory of constraints and system theory of organization. Both descriptive and correlational survey designs were used in executing the research inquiry. The targeted population was 327 beneficiaries of the JEP in Nairobi County. Using Krejcie and Morgan formula, a sample of 181 beneficiaries was selected. Both simple random sampling and purposive sampling were used to choose the sample elements. Data was gathered using structured questionnaires and informant interview guide. Descriptive statistics like percentages, arithmetic mean and standard deviation as well as inferential statistics regression analysis was used in data analysis. Pearson correlation analysis was used to test relationship between variables and regression analysis was applied in predicting the research model. The reliability of questionnaires was ascertained by Cronbach Alpha Coefficient of reliability (at 0.6668). Fisher (F) tested the research hypothesis at α=0.05 whereby, R= 0.563, R2= 0.317, F (1,145) =5.192 at P=0.000-0.05. Therefore, the null hypothesis was rejected as there was enough evidence to conclude that project implementation factors have significant influence on the performance of Jua-kali Empowerment Programmes. Hence recommendations were made to the implementors of Jua-kali empowerment programmes to ensure that the programmes are not only need based but also implemented in an integrated and coordinated approaches for effective realization of projected deliverables.

Abstract Background: The role of sports pharmacists is being emphasized in international athletic events. This study aimed to describe the pharmacy services for the 2019 Fédération Internationale de Natation (FINA) World Masters Championships in Gwangju, South Korea. Method: Research focused on athletes and coaching staff who received medications after visiting medical centers and pharmacies located in the athletes’ village from July 5 to July 29, 2019. Education courses for full-time and volunteer pharmacists were provided three times. We collected daily pharmacy operation results and prescription interventions. The data were analyzed using Microsoft Excel, and were expressed as frequency (%). Results: Throughout the tournament, 633 patients received medication at the athletes’ village pharmacy (gender: 338 men [53.4%], 295 women [46.6%]; nationality: 299 Korean [47.2%], 334 foreign [52.8%]; patient class: 150 athletes [23.7%], 427 non-athletes [67.5%]). Therapy for musculoskeletal disorders was the most common (29, 19.3%), and oral NSAIDs (56, 21.9%) were the most frequently dispensed medication in athletes. Pharmacists intervened for 47 out of 491 prescriptions (9.6%), with dosage change (21, 44.7%) being the most common intervention type. Conclusion: This study on the operation and performance of pharmacies at the FINA World Masters Championships is a useful reference for pharmacy services at international or domestic sports events.
