  • Utilizing a Calcium filter, a large two ribbon flare of an importance 2.5Xj31? was recorded at. King Abdul-Aziz University Solar Observatory (KAAUSO) at the 30th of October 1991. This chromosphenc flare observation, which is of special importance since it is rarely reported, was for a flare that occurred near the south west of the equator at the vicinity of a large sunspot group on an active region known as AR 6891. The observed foot points of this flare had a strange behavior in which the separating motion of the ribbons were not typical of most flares, rather were nearly orthogonal. In this article we present the characteristics of the main sunspot group of this active region and try to investigate its evolution and fragmentation with time. Information regarding magnetic fields and velocity fields are necessary to understand the restructuring of the magnetic field pattern and plasma motion, and hence the changes that could lead to the occurrence of such an interesting flare.

  • In 1991, Malaysia, under the leadership of then-Prime Minister Mahathir Mohamad, launched an ambitious 30-year national development program known as Vision 2020. The goal of this program was to transform Malaysia into a First World developed nation by the year 2020. One of the aspirations of the program was to create a psychologically liberated, secure, ethical, and mature democratic society. Vision 2020 is a failure and Malaysia is still not a mature democracy. This article identifies four main areas that make up a flawed democracy practiced in Malaysia, and shows how they work against the country's aspirations to become a developed nation. The electoral system is rigged to help the incumbent remain in power. The widespread practices of money politics have become a curse to the country. The press and media organizations are restricted. Civil society activities are suppressed. As a result of these issues, Malaysia will not be able to achieve the status of a developed nation, lacking democratic accountability and inclusive institutions.

  • Child abuse is defined as any type of maltreatment and neglect by an adult, which is violent or threatening for a child, including physical violence directed to the child. Children could be abused not only by a parent or caregiver, but also by other adults on whom they are dependent, such as day nursery workers, teachers, and sports coaches. While doctors are the most responsible people for reporting any type of child abuse, their care and awareness seem to be very poor and weak. We reviewed 30 autopsy cases of child abuse, in particular during the past 20 years in Jeju Island. We expect that doctors will report any child abuse more actively after reading this review article.

  • In December 2019, coronavirus disease 2019 (COVID-19) was discovered in Wuhan, China. The disease was so severe that as early as 30 January 2020 COVID-19 was declared by WHO as a Public Health Emergency of International Concern. There have been a lot of concerns about conducting COVID-19 clinical researches scientifically and ethically in pandemic. This article is directed at addressing these issues from the perspective of IRB. First of all, the urgency of COVID-19 research requires prompt IRB process through efficient ethics review and oversight system. IRB should determine whether the risks that will be presented to human subjects are justified after assessing possible harm and anticipated benefits. The safety of subjects should not be compromised. Furthermore, informed consent should be voluntarily obtained by sufficient information in consideration of special circumstances during a pandemic.

  • The Chinese Arbitration Law came into force in 1995 and has been implemented for 26 years. As a party to the New York Convention, there are many contradictions and conflicts between the Chinese Arbitration Law and the New York Convention on the issue of ad hoc arbitration, and this institutional disconnection can bring about problems such as misalignment of arbitration powers. On July 30, 2021, China's Ministry of Justice published a draft of the revised Arbitration Law for public consultation, and the draft has generated a lively debate among the public. This article explores the reasonable and inadequate points of the draft of Arbitration Law in light of the recent trends in the use of commercial arbitration in China, the COVID-19, the Free Trade Zone, and the relationship between the Civil Code and the Arbitration Law.

  • This article describes experimental and numerical analyses of eccentrically loaded over the axially loaded circular concrete filled double-skinned steel tubular (CFDST) short columns. Tests on circular CFDST short columns under eccentric and concentric loading were conducted to assess their responses to the frequent intensity of 5-30 mm at the interval of each 5 mm eccentric loading conditions with constant cross-sectional proportions and width-to-thickness ratios of the outside and internal tubes. The non-linear finite-element analysis of circular CFDST short columns of eccentrically loaded over the axially loaded was performed using the ABAQUS to predict the structural behavior and compare the concentric loading capacity over the various eccentric loading conditions. The comparison outcomes show that the axial compressive strength of the circular CDFST short columns was 2.38-32.86%, lesser than the concentrically loaded short column with the inner circular section. Also, the influence of computer simulation employed is more efficient in forecasting the experimentally examined performance of circular CFDST stub columns.

  • Purpose: This research article investigates the intricate relationship between economic growth and employment in the Korean agri-food industry. Research design, data and methodology: Drawing on Okun's law, which proposes a negative correlation between economic growth and unemployment, the study explores the applicability of this law to different sectors. By focusing on the agri-food industry, the study examines the impact of economic growth on both full-time and temporary employment. Results: The findings highlight the industry's role as a buffer, absorbing workers from other sectors, particularly manufacturing. Moreover, the study reveals that temporary employment is more sensitive to economic growth fluctuations compared to full-time employment. Conclusions: The research emphasizes the importance of implementing employment programs that support transitioning workers in the agri-food industry, facilitating knowledge and skill transfer to ensure sustained employment. Furthermore, it recommends government and company support for temporary employment during buffering periods to ensure safe job transitions. This study provides valuable evidence to understand the nuanced relationship between economic growth and employment in the Korean agri-food industry.

  • The term "peaceful uses of outer space" in the 1967 Outer Space Treaty appears in official government statements and multilateral outer space related treaties. However, the examination of the state practice leads to the conclusion that this term is still without an authoritative definition. As far as the meaning of 'peaceful use' in international law is concerned the same phrases in the UN Charter, the 1963 Treaty of Banning Nuclear Weapons Tests in the Atmosphere in Outer Space and Under Water, the 1956 Statute of IAEA, the 1959 Antarctic Treaty, the 1982 UN Convention on the Law of the Sea, the 1968 Nuclear Non-Proliferation Treaty and the 1972 United Nations Conference of the Human Environment were analysed As far as the meaning of 'peaceful uses of outer space' is concerned the same phrases the 1967 Outer Space Treaty, the 1979 Moon Treaty and the 1977 Convention on the Prohibition of Military or Any Other Hostile Use of Environmental Modification Techniques(ENMOD) were studied. According to Article IV of the 1967 Outer Space treaty, states shall not place in orbit around the earth any objects carrying nuclear weapons or any other kind of weapons of mass destruction, install such weapons on celestial bodies, or station such weapons in outer space in any other manner. The 1979 Agreement Governing the Activities of States on the Moon and Other Celestial Bodies repeats in Article III much of the Outer Space Treaty. This article prohibits the threat or use of force or any other hostile act on the moon and the use of the moon to commit such an act in relation to the earth or to space objects. This adds IN principle nothing to the provisions of the Outer Space Treaty relating to military space activities. The 1977 ENMOD refers to peaceful purposes in the preamble and in Article III. As far as the UN Resolutions are concerned, the 1963 Declaration of Legal Principles Governing the Activities of States in the Exp1oration and Use of Outer Space, the 1992 Principles Relevant to the Use of Nuclear Power Sources in Outer Space(NPS) were studied. And as far the Soft Laws are concerned the 2008 Draft Treaty on the Prevention of the Placement of Weapon in Outer Space and of the Threat or Use of Force against Outer Space Objects(PPWT), the 2002 Hague Code of Conduct against Ballistic Missile Prolifiration(HCoC) and 2012 Draft International Code of Conduct for Outer Space Activities(ICoC) were studied.

  • The present article reports the tracking characteristics of phenolic resin insulation material due to accelerated degradation. For assessing insulation degradation of the phenolic resin insulation material, experiment samples with equivalent years of 0, 10, 20, 30, and 40 years were produced by conducting accelerated degradation experiments using Arrhenius equation. Subsequently, tracking experiments according to KS C IEC 60112 standard were conducted for the experiment samples that were previously subjected to accelerated degradation. According to the measured results for tracking characteristics of phenolic resin subjected to accelerated degradation, upon dropping of 0.1% ammonium chloride, the risks were shown to increase by 1.38 times for the equivalent life of 10 years; 1.45 times for 20 years; 1.62 times for 30 years; and 1.94 times for 40 years based on the equivalent life of 0 year. Upon dropping of 0.01% ammonium chloride, the risks were shown to increase by 1.39 times for the equivalent life of 10 years; 1.52 times for 20 years; 1.99 times for 30 years; and 5.30 times for 40 years. According to the experimental results, the tracking risk was shown to be higher for longer-duration insulation degradation due to aging. In particular, the risk was observed to be greatly increased in the case of the equivalent life of 40 years. Therefore, it is proposed that the occurrence possibility and the risk of electric fires could be minimized through institutional preparation of recommended replacement period by considering risks such as insulation degradation, etc. due to aging.
