The purpose of this study was to explore bringing-up process of mothers with first baby in the context of Korean culture. The field survey was performed with four primiparae during four months from September, 2000 and grounded theory approach was used for data analysis. The results indicated that there were 27 primary categories and 12 secondary categories. Unclearness was extracted as an expression of the core category of bringing-up process. The subjects was faced with care of their baby after delivery and experienced formation and deepening of unclearness. After that, they also went through expression and disentanglement of complication caused by unclearness. It is found that the core concept of this study, the unclereness("Magmagham" in Korean) means a confusion, a burden, a helplessness and a hardness. New mothers make an effort to resolve this situation with strong motherhood in their mind. By supports from significant others, they are empowered and some mothers get depressive feelings. The findings of this study are contributed for nurses to understand new mothers in developmental crisis. We suggested that the nursing intervention strategies including learning baby care skills and preparing emotionally a motherhood must be given new mother during pregnancy period.

Potential air ingress scenarios during accidents in nuclear reactors or spent fuel pools have raised the question of the influence of air, especially of nitrogen, on the oxidation of zirconium alloys, which are used as fuel cladding tubes and other structure materials. In this context, the reaction of zirconium with nitrogen-containing atmospheres and the formation of zirconium nitride play an important role in understanding the oxidation mechanism. This article presents the results of analysis of the interaction of the oxygen-preloaded niobium-bearing alloy $M5^{(R)}$ with nitrogen over a wide range of temperatures ($800-1400^{\circ}C$) and oxygen contents in the metal alloy (1-7 wt.%). A strongly increasing nitriding rate with rising oxygen content in the metal was found. The highest reaction rates were measured for the saturated ${\alpha}-Zr(O)$, as it exists at the metal-oxide interface, at $1300^{\circ}C$. The temperature maximum of the reaction rate was approximately 100 K higher than for Zircaloy-4, already investigated in a previous study. The article presents results of thermogravimetric experiments as well as posttest examinations by optical microscopy, scanning electron microscopy (SEM), and microprobe elemental analyses. Furthermore, a comparison with results obtained with Zircaloy-4 will be made.

Over the last two decades, microbiologically influenced corrosion (MIC) of metallic materials has received considerable attention due to its serious effects on industrial field. In this context, it is important to devise control methods which inhibit biofilm formation on various metallic compounds and are compatible with environment. It was change of various conditions (duty cycle, current density, $AgNO_3$ concentration and pH) for injection of Ag particles in anodized Aluminum alloy pore using pulsed current. Optimal condition was obtained by means of FE-SEM, ICP analysis etc. The antibacterial metal's specimen were manufactured under optimal condition and this specimen were tested the antibacterial characterization and anticorrosion characterization. In result of test, we can confirmed that the antibacterial characterization and anticorrosion characterization of the specimens of injected Ag particles in anodized Aluminum alloy pore using pulsed current were better than the anodized Aluminum alloy specimens.

Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder. NF1 patients are predisposed to formation of several type solid tumors as well as to juvenile myelomonocytic leukemia. Loss of NF1 results in dysregulation of MAPK, PI3K and other signaling cascades, to promote cell proliferation and to inhibit cell apoptosis. The RUNX1 gene is associated with stem cell function in many tissues, and plays a key role in the fate of stem cells. Aberrant RUNX1 expression leads to context-dependent tumor development, in which RUNX1 may serve as a tumor suppressor or an oncogene in specific tissue contexts. The co-occurrence of mutation of NF1 and RUNX1 is detected rarely in several cancers and signaling downstream of RAS-MAPK can alter RUNX1 function. Whether aberrant RUNX1 expression contributes to NF1-related tumorigenesis is not fully understood. This review focuses on the role of RUNX1 in NF1-related tumors and blood disorders, and in sporadic cancers.

Kinematic analyses of magmatic intrusions and faults can provide useful information on stress conditions and chronological relationships between dike emplacement and brittle deformation events. We studied structures in rocks exposed on a coastal platform in Geoje Island off the southern Korean Peninsula because of its well-developed dikes and faults. The geology of the study area includes the Cretaceous Seongpo-ri Formation, which is composed mostly of shale, sandstone, and hornfels intruded by magmatic dikes. Most of the dikes are developed along pre-existing structural features (faults and fractures), indicating that their emplacements were structurally controlled. Because dikes commonly open along the direction of the minimum principal stress, the direction of this stress can be obtained from dike geometry and orientation through the matching of piercing points on either side of a dike. In addition, the deformed dikes can give information regarding later deformation. On the basis of the kinematic analyses, we identified five deformation events in the study area, which are kinematically related to changes of the regional maximum principal stress. Results indicate that the structures in the study area have been controlled predominantly by episodes of reactivation of the NNE-trending Yangsan strike-slip fault, located to the northeast of the study area, under different stress regimes. In a wider tectonic context, the brittle deformation of the rocks of Geoje Island was probably induced by interactions among the Philippine Sea, Pacific, and Eurasian plates, including changes in subduction parameters with respect to the latter two plates over time.

Objective: The purpose of this study is to examine young children's social experiences during COVID-19. In this study, social experiences are defined as children's social interactions and relationships, their educational experiences, and their daily life experiences in child care centers. Methods: Participants include nine child care teachers and fifteen young children. Data were collected through semi-structured interviews with individual teachers, interviews with young children, and small group storytelling activities with young children. Results: The main findings in exploring meanings and implications of childcare consulting were as follows. First, childcare consulting was recognized as a process of learning about changes through mutual relationships. Second, the different ways to practice childcare consulting, the formation of the learning culture of an organization to help experience collective intelligence, the process of finding various solutions through mutual communication, and the improvement of childcare teachers' professional capabilities while reflecting the current times and context were all investigated. Conclusion/Implications: Given the findings of the study, the importance of childcare consulting, and the ways to establish its systems were discussed.

In April, 2020, amid widespread fear of a second wave of infections of the novel coronavirus in China, local authorities in Guangzhou cracked down on the city's black population, resulting in mass evictions of Africans. The incident raises several questions about racism in China. How should we interpret this heavy-handed treatment of black people? Was this an isolated incident? What motivated such operations? In this article, I explain social control of Guangzhou's African communities as a problem of municipal politics. What underlies the government's heavy handed approach, I argue, are those communities' ties to rurality, which constitute a roadblock in the city's urban upgrade. Using Dengfeng Village, one of the best known African communities in China, as a case study, I show that efforts to upgrade the area by the local state and the real estate industry were frustrated by the community's status as an urban village. Africans, whom Chinese have historically associated with rurality, are seen as contributing to a space that has long been stigmatized as a spatial manifestation of rural people's lack of self-discipline. To better reveal the interconnection between social control and urban politics, I place official action in context of the history of the community's formation and the lived experience. This analysis of Dengfeng applies to various extents to other major African communities in Guangzhou.

This article is a sub-section of a comparative analysis of depictions of violence in Jakarta's Museum of the Indonesian Communist Party's Treachery, Ho Chi Minh City's War Remnants Museum, and Phnom Penh's Tuol Sleng Genocide Museum. In comparing these public history sites, I analyze how memories of mass violence were central to state formation in both Suharto's anti-Communist New Order (1966-1998), the Socialist Republic of Vietnam (1976-present), and Cambodia since the collapse of Democratic Kampuchea (1979-present). While this comparison points out specific distinctions about the role of the military, the nature of revolution, and conceptions of gender, it argues for a central similarity in the use of a mythology of victimization in building these post-conflict nation-states. This article focuses on my gendered analysis of the use of images of women and children in each museum. Depending on context and political purpose, these museums cast women as tragic victim, revolutionary heroine, or threat to the social order. My analysis of gender places stereotypical images of violence against women (the trope of women and children as the ultimate victims) in conversation with dark fantasies of women as perpetrators of savage violence and heroic images of women liberated by participation in violence.
