This article describes the process of financial subjectification by observing a private educational programme on financial self-management in South Korea. 'Wealth-tech' is a popular Korean term that refers to techniques of personal finance and money-management. Ethnographic research on a private educational programme on the subject of wealth-tech brings to light justifying mechanisms of financial investments and moral foundations for the pursuit of wealth whereby laypeople's engagement with, and attachment to, financial markets are (re-)vitalized. In particular, this study highlights the role of critiques about capitalism as well as the production of affect in the making of financial subjects. By re-appropriating critiques of capitalism and employing therapeutic narratives, the wealth-tech pedagogy redefines financial investment as an act of resistance against the ills of capitalism and foreign capital. Moreover, this case study shows that wealth-tech is legitimized not solely by risk calculations per se, but also by feelings of hurt. Participants tend to transform themselves into active wealth-tech practitioners by cultivating the kind of affect that I call here 'thinking rich, feeling hurt'. Therefore, the financial subjects configured in this wealth-tech pedagogy are those who feel hurt, and in this emotive state are led to think from the perspective of the rich. Moreover, they are configured not only as selfgoverning individuals but also as collective beings who resist foreign capital through their own engagement with financial markets. In this process of financial subjectification, the beliefs that finance can make them rich become consolidated. By illustrating these Korean experiences, this article calls attention to critical and affective practices in the process of financial subjectification, in particular those that take shape at the encounter between market rationality and ordinary experiences, memories, and feelings whereby laypeople translate discourses and techniques of financial capitalism into their own values and judgments.

Knee osteoarthritis is the most common debilitating health condition affecting elderly population. MR imaging of the knee is highly sensitive for diagnosis and evaluation of the extent of knee osteoarthritis. Quantitative analysis of the progression of osteoarthritis is commonly based on segmentation and measurement of articular cartilage from knee MR images. Segmentation of the knee articular cartilage, however, is extremely laborious and technically demanding, because the cartilage is of complex geometry and thin and small in size. To improve precision and efficiency of the segmentation of the cartilage, we have applied a semi-automated segmentation method that is based on an s/t graph cut algorithm. The cost function was defined integrating regional and boundary cues. While regional cues can encode any intensity distributions of two regions, "object" (cartilage) and "background" (the rest), boundary cues are based on the intensity differences between neighboring pixels. For three-dimensional (3-D) segmentation, hard constraints are also specified in 3-D way facilitating user interaction. When our proposed semi-automated method was tested on clinical patients' MR images (160 slices, 0.7 mm slice thickness), a considerable amount of segmentation time was saved with improved efficiency, compared to a manual segmentation approach.

Starting with an online financial community in South Korea, this article explores the simultaneous production of a new form of subjectivity and a networked ecosystem of financial cultures. Using a multi-sited ethnography to track the movements of users as they moved across different spaces, this article finds that users gifted financial information to each other, blended laity and expertise, and reappropriated financial communities into a third place defined as an informal, public place hosting sociable conversations. Through the grafting of prosocial activities (e.g. sharing, gifting, and social networking) onto financial self-management, users were shaped as networked financial subjects and exhibited a distinctive mode of selfhood informed by both financial subjectivity and neoliberal networked subjectivity. At the same time, their practices spawned countless social, convivial groups as well as entrepreneurial financial gurus. By demonstrating the complex webs of on- and off-line groups, programs, relationships, and social networks, this article illustrates how the networked ecosystem of financial cultures brought the markets and commons into coalescence.

In this study, a parametric study is performed to investigate the squeal noise of an automobile water pump. The squeal noise studied in this paper is generated by the self-excited torsional resonance of the rotating shaft, and this noise is related to the stick-slip phenomenon of the mechanical seal in the water pump. The mechanical seal friction has the characteristics of the negative velocity-gradient. The equations of motion of multiple-degree-of-freedom torsional vibration model is constructed by the Holzer's method and then the equation is transformed to an equivalent single-degree-of-freedom torsional resonance simulation model. A squeal noise criteria is determined by the simulation model to perform the parametric study. The design parameters(the mass moment of inertia of the pulley, the mass moment of inertia of the impeller, the length of the shafts, the radius of the shafts, spinning speed of the shafts, the position of the mechanical seal, radius of the mechanical seal, and normal load of the mechanical seal) are investigated to confirm the stability for the squeal noise.*
