  • In this paper, Ni Germane-silicide formed on undoped $Si_{0.8}Ge_{0.2}$ as well as source/drain dopants doped $Si_{0.8}Ge_{0.2}$ was characterized by the four-point probe for sheet resistance. x-ray diffraction (XRD), x-ray photoelectron spectroscopy (XPS) and field emission scanning electron microscope (FESEM). Low resistive NiSiGe is formed by one step RTP (Rapid thermal processing) with temperature range at $500{\~}700^{\circ}C$. To enhance the thermal stability of Ni Germane-silicide, Ni/Co/TiN structure with different Co concentration were studied in this work. Low sheet resistance was obtained by Ni/Co/TiN structure with high Co concentration using 2-step RTP and it almost keeps the same low sheet resistance even after furnace annealing at $650^{\circ}C$ for 30 min.

  • This article discusses a diagnostics method based on models, and information theory. From an extensive system dynamics bond graph model of a gearbox [1], simulated were various cases germane to this diagnostics approach, including the response of an ideal gearbox, which functions perfectly to designer's specifications, and degraded gearboxes with tooth root cracking. By comparing these cases and constructing a signal flow analogy between the gearbox and a communication channel, Shannon' s information theory [2], including theorems, was applied to the gearbox to assess system health, in terms of ability to function.

  • The purpose of this study is to review the essentials of teaching-effectiveness affecting the students' achievement. Any discussion of psychological research and theory concerned with the way teachers affect student learning must consider a variety of issues germane to this research. These issues provide a context for interpreting the research presently available and for identifying an appropriate agenda for future research.Finally, research on teacher effects needs to expand its concern for the psychological mechanisms that are responsible for student learning from instruction. Within the context of this study, that concern is probably the major challenge facing educational psychologists interested in the teaching-learning process.

  • The patellofemoral pint is formed by the articulation of the patella and femoral condyles in the trochlear groove. The complexity of the patellofemoral pint is magnified by the fact that the tibiofemoral pint works in conjunction with the patellofemoral pint. Additionally, other pints such as the subtalar pint., hip and sacroiliac pints indirectly contribute to the function of the patellofemoral pint. This pint has little bony stability, Soft tissue surrounds the pint to increase stability. The patellofemoral pint increases the mechanical advantage of the quadriceps muscles and resists mechanical loading. In patellofemoral dysfunction, patellofemoral contact pattern is disrupted. leading to excessive compression at the pint. When you treat the patellofemoral dysfunction, you should evaluate anatomic and biomechanic components and find factors of patellofemoral dysfunction. Hamstring tightness. weakness of VMO and tightness of lateral retinaculum lead to flexed knee and abnormal patella tracking and patellofemoral pint reaction force and patellofemoral dysfunction. A through understanding of the anatomy and biomechanics may assist the clinician in the recognition and treatment of patients with patellofemoral pain. Therefore physical therapists should apply modality as well as therapeutic exercise, stretching and strengthening. In this paper, I will discuss the germane anatomical structures and biomechanics of the patellofemoral pint.

  • Purpose - The purpose of this paper is to review, analyze and identify the suitability of Kazakh gender policy for the changes taken place in the society with suggesting necessary changes. Research design, data, and methodology - After meticulous reviews of germane literature, the researchers applied an analytical approach which focuses on analyzing the Kazakh's gender policy and its issuance guidelines based on the present requirement in the society. Even though the policy has introduced with astonishing prudence, present-day living trends in society require imperatively some notable modifications which protect the rights of women and minority sections of the society. Results - Through this gender policy, government has proffered required legal, financial and preferential support country's women to participate in the management and legislation of the country. Kazakh gender policy requires upgradations which flawlessly support women in the lifestyles of the feminine community. Conclusions - In achieving gender equality in the economy as a priority area, Kazakh government monitoring persistently and closely the changing trends of women and their requirements which introduce necessary modifications to the existing gender policy of the country with the cooperation of international organization.

  • Statement of problem. The effects of surface roughness have not or insufficiently been analyzed on earlier events such as cell adhesion though cell behavior most germane to implant performance is cell adhesion. Purpose. The purpose of this study was to evaluate cell adhesion of osteoblast-like cells (MG63) onto three types of titanium disks with varying roughness using the Elisa assay. Materials and methods. Representative disks from each group (SLA, HA, machined) were subjected to surface analysis and surface roughness was measured by the optical interferometer (Accura 2000, Intekplus Co., Seoul, Korea). Following this, MG63 cells were cultured on the titanium disks and released. Cell adhesion measurements using the Elisa assay were performed specifically at three points: after 24, 48, and 72 hours of culture. Results. Among the 3 types of surface analyzed, the SLA surface was the roughest with a Ra value of $1.114{\mu}m$ followed by HA coated surface and machined surface, consecutively. The optical density values for the SLA surface group was significantly higher than that of the machined and HA coated surface groups following 24 and 48 hours of culture. The cell culture on HA coated surface showed significantly higher values compared to the machined surface following 24, 48 and 72 hours of culture. Conclusion. The results suggest that surface treatment of titanium surfaces enhanced cell adhesion of human osteoblast-like cells (MG63).

  • The purpose of this research is to examine reasons and evaluate strategies implemented by the Indian banking industry in tackling jay-customers in general and in light of the recent demonetization in particular. After a thorough germane literature and theoretical framework on jay-customers and Indian banking industry, researchers framed a well-structured questionnaire for collecting banking employees opinions along with a set of questions framed to conduct in-depth personal interviews with banking customers. The collected data were summarized, coded, and controlled by using Software R and the selected hypotheses were analyzed by the observance of percentile values. More than 90 percent of banking employees said lack of proper supply of cash from the Reserve Bank of India is the major reason for this kind of customer behaviour and shockingly 95 percent of banking customers expressed backdoor preference given by banking employees to some big customers is the major reason. The research confined only two state capitals Amaravati and Bangalore in India and covered only two largest banks one in public and private sector. The research provides useful insight into the crucial reasons for jay-customers' behaviour from the dyadic perspective of both employees and customers of the Indian banking industry.

Incarnation and Divine Essence in Daesoon Thought: A Comparative Study between Daesoon thought and Christianity

  • This article compares the concepts of divine incarnation as expounded in Daesoon Thought and in Christianity and questions the essence of the divinity in both traditions. In Daesoon Thought, The Supreme God, Sangje, saw major disorganization leading to extreme violence and doom and decided to incarnate on earth under the human form of Kang Jeungsan (1871-1909). Then the living God taught the solution to human suffering through the revelations he sent in 1917 to Jo Cheol-Je, or Jo Jeongsan (1895-1958) and the revelations were passed on to Dojeon Park Wudang who in 1969 founded Daesoon Thought. In Christianity, God incarnated in his son, Jesus Christ, who allowed for the radical transformation of the condition of man through his physical sacrifice. Daesoon differs in that Sangje did not offer himself as sacrifice when he came on earth but reorganized the world and taught how to apply benevolence to establish the Earthly Paradise. The affirmation that Daesoon Jinrihoe is both monotheistic and polytheistic is then analyzed. If the concept of monotheism seems to differ vastly between the two traditions, it appears that biblical monotheism is itself relatively young in the history of world religions so that Christianity has ancient roots germane to those of Daesoon Jinrihoe. The article concludes on the originality of this religion: though it is built on Daoism, Buddhism and Confucianism, it has transformed their vision of the deity and of its message in a most convincing manner.

  • Turbulent flow over a fully-developed wavy channel is investigated by the nonlinear $k-\varepsilon-f_\mu$ model of Park et al.(1) The Reynolds number is fixed at $Re_{b}$ = 6760 through all wave amplitudes and the wave configuration is varied in the range of $0\leq\alpha/\lambda\leq0.15$ and $0.25\leq{\lambda}/H\leq4.0$. The predicted results for wavy channel are validated by comparing with the DNS data of Maa$\beta$ and Schumann(2) The model performance Is shown to be generally satisfactory. As the wave amplitude increases, it is found that the form drag grows linearly and the friction drag is overwhelmed by the form drag. In order to verify these characteristics, a large eddy simulation is performed for four cases. The dynamic model of Germane et al.(3) is adopted. Finally, the effects of wavy amplitude on separated shear layer are scrutinized.
