Taylor-Couette flow (i.e., flow between concentric, rotating cylinders) has long served as a paradigm for studies of hydrodynamic stability. For Newtonian fluids, the rich cascade of transitions from laminar, Couette flow to turbulent flow occurs through a set of well-characterized flow states (Taylor Vortex Flow, wavy Taylor vortices, modulated wavy vortices, etc.) that depend on the Reynolds numbers of both the inner and outer cylinders ($Re_i$ and $Re_o$). While extensive work has been done on (a) the effects of weak viscoelasticity on the first few transitions for $Re_o=0$ and (b) the effects of strong viscoelasticity in the limit of vanishing inertia ($Re_i$ and $Re_o$ both vanishing), the viscoelastic Taylor-Couette problem presents an enormous parameter space, much of which remains completely unexplored. Here we describe our recent experimental efforts to examine the effects of drag reducing polymers on the complete range of flow states observed in the Taylor-Couette problem. Of particular importance in the present work is 1) the rheological characterization of the test solutions via both shear and extensional (CaBER) rheometry, 2) the wide range of parameters examined, including $Re_i$, $Re_o$ and Elasticity number E1, and 3) the use of a consistent, conservative protocol for accessing flow states. We hope that by examining the stability changes for each flow state, we may gain insights into the importance of particular coherent structures in drag reduction, identify simple ways of screening new drag reducing additives, and improve our understanding of the mechanism of drag reduction.

New types of protocols have been recently in development, all based on an absorbed dose-to-water with the aim of improving the accuracy of measurements of absorbed dose to water. IAEA TRS-277, the air-kerma standard-based present protocol, and IAEA TRS-398 and AAPM TG-51, the absorbed dose-to-water standard-based new one, were studied and compared theoretically and experimentally for photon beams of 6, 10, and 15 MV. NE 2571 and 3 Farmer types of ionization chambers in widely commercial use were used to determine an absorbed dose to water at the reference depth in water. Two different kinds of calibration factors were given respectively for every chamber calibrated in $\^$60/CO gamma ray beams from a Korean Secondary Standard Dosimetry Laboratory (KFDA). This work shows that there is around 1 % of difference of absorbed doses measured between two different types of calibration systems owing to different physical parameters and reference conditions used. We hope this work to help form the basis on development of new type of protocol in Korea.

Childhood Cancer Foundation of ROC(CCFROC) has been founded since 1982. Its goal is to provide comprehensive care for cancer children and their families. And in turn, under the provision of good and complete care, they can be back to the school and society. To achieve this goal, it needs to get every body's effort of the society together. The foundation has been founder under this concept and tried to fulfil this task. The first step is to educate the public to know that childhood cancer can be cured and the process of treatment is long and expensive. In order to reach this life-saving procedure, campaigns for raising money is most important thing. Then, pediatric hematologists / oncologists try to organize study group, named Taiwan Pediatric Qncology Goupp(TPOG), to make treatment protocols for childhood cancers. Its primary purpose is to increase the cure rate to prove the earlier the diagnosis and treatment, the better the prognosis. The second step is to provide full support of medical expenses and further to give help for emergent need to living. Through the varieties of active exercises of cancer children or families, foundation provides opportunities for them to share the experience during the different periods of diseases. The third step is to extend the scope of training activities for many kinds of personnel who devote to the care for cancer children. On the other hand, it promotes the cooperation or communication with international organizations and sets up recreation playing ground in the communities. The aim is to provide a comprehensive and integrated care for cancer children during their education, breeding and even accomplishment period. Besides the financial support of medical care, it provides social services to give psychological support for children and their families, to strengthen doctor-patients or doctor-families relationship. The foundation provides the mourning religious activities to cherish the memory of their children who passed away and to comfort their sadness. Since the childhood cancer is curable, its treatment should be active, comprehensive and it needs to provide to all cancer children without exception. Indeed, the work of CCFROC should be changed according to the environment and different time period. But, it needs the full support from the society. We hope the scope and content of the work will be more extended and its achievement will be better than now in the future.

Defense-in-depth is a fundamental safety principle for the design and operation of nuclear power plants. Despite its general appeal, defense-in-depth is not without its drawbacks, which include its potential for concealing the occurrence of hazardous states in a system, and more generally rendering the latter more opaque for its operators and managers, thus resulting in safety blind spots. This in turn translates into a shrinking of the time window available for operators to identify an unfolding hazardous condition or situation and intervene to abate it. To prevent this drawback from materializing, we propose in this work a novel safety principle termed "observability-in-depth". We characterize it as the set of provisions technical, operational, and organizational designed to enable the monitoring and identification of emerging hazardous conditions and accident pathogens in real-time and over different time-scales. Observability-in-depth also requires the monitoring of conditions of all safety barriers that implement defense-in-depth; and in so doing it supports sensemaking of identified hazardous conditions, and the understanding of potential accident sequences that might follow (how they can propagate). Observability-in-depth is thus an information-centric principle, and its importance in accident prevention is in the value of the information it provides and actions or safety interventions it spurs. We examine several "event reports" from the U.S. Nuclear Regulatory Commission database, which illustrate specific instances of violation of the observability-in-depth safety principle and the consequences that followed (e.g., unmonitored releases and loss of containments). We also revisit the Three Mile Island accident in light of the proposed principle, and identify causes and consequences of the lack of observability-in-depth related to this accident sequence. We illustrate both the benefits of adopting the observability-in-depth safety principle and the adverse consequences when this principle is violated or not implemented. This work constitutes a first step in the development of the observability-in-depth safety principle, and we hope this effort invites other researchers and safety professionals to further explore and develop this principle and its implementation.

In the global context, particularly in Christian nations, Christmas is considered a culturally and ethically significant time. In this study, we examine Charles Dickens' novel, "A Christmas Carol," and the celebration of Christmas in Korea. We explore the values of Christmas in Korea derived from the significance and importance of this novel. These values include repentance, empathy, compassion, and the importance of humanity. Korean Christmas is regarded as a time for practicing these values, bearing a message akin to the transformation of characters like Scrooge. Furthermore, "A Christmas Carol" conveys a message of improvement and change over time, emphasizing change and growth in Korean Christmas. People reflect on their past, correct their mistakes, nurture hope for the future, and experience personal growth and transformation. Additionally, the novel raises awareness of social injustice and inequality, offering alternatives. In Korean society, Christmas encourages the willingness to care for and help others, facilitating discussions and understanding of societal issues. For these reasons, "A Christmas Carol" is considered a culturally and ethically significant time in Korean Christmas, and the two are intertwined in various aspects. This study explores the interaction between cultural change and ethical teachings by 'A Christmas Carol' and investigates the impact of this work on Christmas culture and social change. It serves as the basis for emphasizing moral principles and humanity during the Christmas season, and this research provides suggestions for future research directions, aiming to deepen the understanding of Dickens' work and the importance of "A Christmas Carol." Through these efforts, it is expected that valuable insights into the connection between Christmas culture and moral messages will be gained. In this study, we will delve into the enduring appeal and cultural significance of "A Christmas Carol," discussing how this novel has evolved into a beloved holiday tradition and a true symbol of Christmas. We will also examine the adaptation of this novel into various media and its influence on holiday season celebrations. Insights into the impact of this novel on Korean society and its continued significance in modern times will be provided, suggesting a direction for a healthier and more desirable path for Korean society.

Ball reducer (HERB Drive: High Efficient Wave Rolling Ball Drive) with waved grooves has many advantages over other types of reducers for high-reduction ratio, low noise and low energy loss, etc. The mechanism of force transmission is very similar to that of cam and follower in automobile valve train system especially in contact behaviors. In this study, we have investigated the traces of contact between ball and outer ring, and the dynamic contact behaviors of elastohydodynamic lubrication(EHL) with a certain reduction ratio. In order to verify the contact behaviors between ball and outer ring for the critical endurance lift, the contact velocity and load are computed for a cycle. During some intervals of a cycle, the contact velocity reverses its direction very suddenly. It is expected that changing the contact direction causes undesirable endurance performance because EHL film frequently col lapse at the moment of velocity reversal. From the computational investigation in this work, we hope to predict similar contact damages in other machinery due to this kind of contact behaviors, which is very typical in many contact phenomena.
