  • The policy trends of use and the development of nuclear power in the United States, France, United Kingdom. Germany, Russia, China, Japan and Korea are briefly investigated. Nuclear power technology has been developed as the national policy in the nuclear-advanced countries. 50 years has passed since the declaration of "Atoms for Peace" by USA President Eisenhour in December 1953. Recently, it appears to revitalize the nuclear power program in world major countries in order to recover the shortage of electric power and to curb the excess emission of carbon dioxide as well as to secure competitiveness in electricity markets. Advanced countries are making new initiatives for the development of the fourth generation nuclear power system. Furthermore, wide-ranged use and development of nuclear power technologies are expected in district heating in commercial sectors, power in the space exploration, and propulsion power of large tankers and spaceships. High temperature gas cooled nuclear power reactor will be applied for mass production of hydrogen energy in the future.

  • Based on the hypothesized model and the data obtained from the questionnaire, this paper analyzed the data using the statistical analysis software SPSS 25.0 and AMOS 20.0 to empirically prove the relationship between the variables of transformational leadership, organizational support, organizational justice, and employee engagement. It was found that: First, transformational leadership has a significant positive effect on employee commitment; Second, transformational leadership has a significant positive effect on perceived organizational support. Third, perceived organizational support has a significant effect on employee commitment; Fourth, in the relationship between transformational leadership and employee commitment, the mediating effect of perceived organizational support on them holds; At last, organizational justice plays a moderating role in the relationship between transformational leadership and the perceived organizational support. This study enriches and integrates the theoretical systems and research categories of employee engagement, organizational justice, transformational leadership, and perceived organizational support.

  • Process Capability Indexes(PCI) are used as the measure for evaluation of process capability analysis and is the statistical method for efficient process control. The fourth generation $PCI(C_{psk})$ is constructed from $C_{pmk}$ by introducing the factor $\mid\mu-T\mid$ in the numerator as an extra penalty for the departure of the process mean from the preassigned target value T And Process Incapability Indexes(PII) are presented by inversing PCI and include the information of PCI. This paper introduces the PII $C_{ss}^*$ provide manager with various information of process and include Gage R&R. PII $C_{ss}^*$ is presented by inversing PCI $C_{psk}$ and include the information of PCI $C_{psk}$.

  • Because of the international marriage of bachelors in the rural areas, there have been grown many foreign residents, the Multi-cultural families. For the improvement of multi-cultural families, the first important thing is their early settlement in Korea. For those foreigners' settlement, systematic approach to Korean education program is necessary. Second, multi-cultural families need support to maintain their basic lives safely. Agricultural education for the next generation is, moreover, also important for them. Third, healthy growth and training for the formation of the Self-Identity of their children are needed for those multi-cultural families too. Education for bring up their children as the global talents, the cost of private education and the one of bringing up children also have to be supported. Fourth, the improvement of understanding multicultural families is significant. Development and education of various programs to participate multi-cultural families are also required.

  • This paper. we investigate the OFDM-based wireless LAN systems operating in the 60 GHz frequency band as part of the fourth-generation (4G) systems. The 60 GHz band is of much interest since this is the band in which a massive amount of spectral space (5 GHz) has been allocated worldwide for dense wireless local communications. This paper gives an overview of 60 GHz indoor wireless channel characteristics and an effect on phase noise. The performance of OFDM system is severely degraded by the local oscillator phase noise, which causes both common phase error and inter-carrier interference. We provide the exact analysis of the phase noise effect on the OFDM system.

  • Electrochemical oxidation of ethanol has been studied at nickel and $RuO_2-modified$ nickel electrodes in 1 M KOH using electrochemical impedance spectroscopy. Equivalent circuits have been worked out from simulation of impedance data to model oxidation of ethanol as well as the passivation of the electrode. The charge-transfer resistances for oxidation of these electrodes became smaller in the presence of ethanol than in its absence. The nickel substrate facilitated ethanol oxidation at $RuO_2-modified$ nickel electrodes. We also describe the Performance of nanosized electrocatalysts of the same composition in comparison to those of the bulk electrodes. The nanosized electrodes were obtained by electrode-positing the alloy from complexed form of these metal ions with fourth and fifth generation polyamidoamine dendrimers.

  • Tar Baby, Toni Morrison's fourth novel re examines the problem that black characters face in negotiatiating a place for themselves within a dominant culture, with respect to their own history and culture. The novel critiques the dominant socio economic and commodifying cultural space from which the black woman seems to have no escape. Jadine is a colonized subject, for as a fashion model she has surrendered to an aesthetics of commodification, and as a student of art history, she has internalized the capitalist ethic of the white culture industry. Though she has ensured her freedom, Morrison's critique of her separation from her family and culture is unmistakable. Interwoven with her narrative is Son's predicament, the stereotype of a black racist and her 'lover'. The novel ends with him at the crossroads of culture, yet signaling his passage to freedom through resistance. The paper arguments how Toni Morrison has envisioned the welfare of African American community by reconstructing the role of new black generation, as represented by Jadine and Son, whose new journey towards their self fulfillment just not only bring their personal freedom but also regenerates African American community by resisting dominant commodifying cultural.

  • Endometriosis is characterized by the implantation of endometrial cells outside the uterus. This hormone-dependent disease is highly prevalent among women of reproductive age. Clinical symptoms of endometriosis include dysmenorrhea, pelvic pain, and infertility, which can negatively impact the overall quality of life of those affected. The medical treatment of endometriosis serves as an important therapeutic option, aimed at alleviating pain associated with the condition and suppressing the growth of endometriotic lesions. As such, it is employed as an adjuvant therapy following surgery or an empirical treatment after the clinical diagnosis of endometriosis. Dienogest, a fourth-generation progestin, has received approval for the treatment of endometriosis in many countries. A growing body of evidence has demonstrated its efficacy in managing endometriosis-associated pain, preventing symptoms, and reducing lesion recurrence. In this review, we examine the clinical efficacy, safety, and tolerability of dienogest in treating endometriosis. We also provide updated findings, drawing from clinical studies that focus on the long-term use of this medication in patients with endometriosis.

  • This paper draws attention on the importance of computational thinking, which is being utilized more and more in recent educational environment. Also, it suggests a teaching and learning model for improving computational thinking within early childhood education. With the advent of the Fourth Industrial Revolution, this era demands people to possess integrative thinking and problem-solving skills. As a result, education on computational thinking is done beginning from the early childhood, enabling children to take the leading part in the future digital generation. However, despite the appearance of many education services and products regarding computational thinking, the field lacks evaluation and academic verification. Thus, this study will complement the methodological aspect of computational thinking.
