In recent years, the material has mattered to the humanities and social sciences in the West and feminism is no exception. It is a notable change that feminist analyses, which had previously shown critiques against science and technology, attempted to build new engagements with matter. STS (science and technology studies) has also accumulated scholarships and developed conceptual tools on the thing or the existence itself through "the ontological turn." The objective of this paper is not to introduce new materialism or new material feminism in full, but to reveal the possibility and potential of doing science, technology and women studies by selectively relying on the achievement of new materialism feminism. This article shows a way to study women's practice of science and technology by analyzing the case of plastic surgery practices through the ontological concepts of STS, particularly those of Annemarie Mol, Karen Barad, and Charis Thompson, and proposes a new engagement among new materialism, feminism, and STS. This article is organized as follows. First of all, after briefly discussing main issues in new material feminism, I will show the limitations of previous feminist studies of plastic surgery under the light of new material feminism. The rest of the article introduces the conceptual tools of ontological STS, describes plastic surgery practices with those tools, and finally provides their feminist implications.

Listeria (L.) monocytogenes in samples could not be detected occasioally by faster growth of other Listeria spp. especially L. innocua. The aim of this study was to develop the differential media and multiplex polymerase chain reaction (PCR) assays for the rapid detection of L. monocytogenes. L. monocytogenes colonies were characterized by their ${\beta}$-hemolysis with fluorescence under 366 nm UV light on the Listeria hemolysis agar (LHA). L. innocua, a species commonly present in foods, did not produce ${\beta}$-hemolysis on LHA. Therefore, one or more colonies of L. monocytogenes were easily distinguished from large populations of L. innocua. The multiplex PCR assays were developed to distinguish from L. monocytogenes and other Listeria spp. with two pairs of primers. The primers were designed in 16S rRNA and listeriolysin O gene for specific amplification of all members of the genus Listeria and L. monocytogenes, respectively. The multiplex PCR assays produced 560 and 938 bp products in L. monocytogenes; only 938 bp products in the genus Listeria. The multiplex PCR assays could detect as little as 50 pg of L monocytogenes DNA. These results indicated that the differential media and multiplex PCR assays might be useful diagnostic tools for the rapid detection of L. monocytogenes.

Cancers claim millions of lives each year. Early detection that can enable a higher chance of cure is of paramount importance to cancer patients. However, diagnostic tools for many forms of tumors have been lacking. Over the last few years, studies of chimeric RNAs as biomarkers have emerged. Numerous reports using bioinformatics and screening methodologies have described more than 30,000 expressed sequence tags (EST) or cDNA sequences as putative chimeric RNAs. While cancer cells have been well known to contain fusion genes derived from chromosomal translocations, rearrangements or deletions, recent studies suggest that trans-splicing in cells may be another source of chimeric RNA production. Unlike cis-splicing, trans-splicing takes place between two pre-mRNA molecules, which are in most cases derived from two different genes, generating a chimeric non-co-linear RNA. It is possible that trans-splicing occurs in normal cells at high frequencies but the resulting chimeric RNAs exist only at low levels. However the levels of certain RNA chimeras may be elevated in cancers, leading to the formation of fusion genes. In light of the fact that chimeric RNAs have been shown to be overrepresented in various tumors, studies of the mechanisms that produce chimeric RNAs and identification of signature RNA chimeras as biomarkers present an opportunity for the development of diagnoses for early tumor detection.

The purpose of this study is two-fold: first, to examine the current status of e-dictionary use in Korea and the attitude toward its use by Korean college students; second, to investigate to what degree e-dictionaries may be useful and effective tools in helping to improve learners' overall English skills. The subjects were 84 college students and they were divided into two groups: the experiment group and the control group. The instrument employed was the Preliminary Student Usage Questionnaire, which was developed by the researcher, together with the questionnaire survey developed by Koyama and Takeuchi (2004), which was modified for the study. The findings from this research are as follows: First, a special instruction session on how to use e-dictionaries made a statistically significant difference among users of the dictionaries. Those subjects who had received the instruction displayed a more positive attitude toward the use of e-dictionaries. Second, the experiment group showed a more favorable attitude toward the use of e-dictionaries. On the basis of the above results, the researcher suggests that proper guidance on the use of e-dictionaries and their benefits should have a positive influence on users. The findings from the current research will shed light on the current status of electronic dictionary use among Korean college students.

Skin cancer, which often occurs as a result of skin exposure to ultraviolet light radiation, usually presents with characteristic abnormal features, such as ulcerative lesions, irregular morphology, bleeding, and excessive growth. Therefore, skin cancer rarely resembles a benign tumor on visual inspection. Nonetheless, squamous cell carcinoma and basal cell carcinoma with nodular or polypoid features can have a similar appearance to that of benign tumors, meaning that they are sometimes misdiagnosed as benign. As benign and malignant tumors have some overlapping features, clinicians sometimes use additional imaging techniques such as ultrasonography to improve the accuracy of the diagnosis because even a malignant tumor that externally resembles a benign tumor generally has internal morphological features characteristic of malignancy, such as invasion and irregular borders. However, these imaging tools also have limitations, and punch or excisional biopsy can be needed if malignancy cannot be completely ruled out. Herein, we report a case of skin malignancy initially misdiagnosed as a benign epidermal cyst based on external visual inspection and ultrasonography.

The water entry forces acting on an air-dropped torpedo are of the restrictions on launch speed and launch altitude, because it could cause the structural damage to components of torpedo. Therefore, it is necessary to estimate the water entry forces with confidence according to launch conditions. In this study, an approximation method for water entry forces is presented, and the results using this approximation are compared with those of other numerical methods. The magnitude and duration of impact forces estimated by the present approximation agree with those of impact by the analysis of ideal or viscous flow. This method can give useful tools to select the launch in initial design stage.

Forging operations are non-stationary processes occurring because of indirect pressure, generally, under conditions of three-dimensional stress and deformation. Furthermore, due to friction and the constraints of die geometry, deformation is not homogeneous. Material flow and deformation are largely determined by the shape of the tools. It is well known that net-shape forging can improve the mechanical strength of the final product as well as reduce material waste. Oxygen-free copper that is used for electrical and electronic components has excellent electrical and thermal conductivity. Oxygen-free copper parts have a low productivity in cutting process. Thus, the forging process is performed in order to improve the low productivity in cutting process. The forging of oxygen-free copper for electrode body parts was modeled using finite element simulation and forging experiments that were conducted for producing electrode body parts at room temperature. In order to reduce the cost of cutting products, the forging was performed in a closed cavity to obtain near-net or net-shape parts.

System Intergration (SI) has resently been conceived as one df the most important tools for enforciong and reinforcing the competitiveness of an enterprise. A major concern of SI lies in sharing many types of information, such as engineering, production, finance, marketing, and so on. Product Data Management (PDM) systems are mainly concerned with product- related information, and also support a large portion of the Commerce At Light Speed (CALS) straitegy. PDM systems receive a great amount df attention form industry, A variety of PDM solutions have been introduced for the last few years, and its market has expanded very fast with an annual growth of 30%. However, in general, it is not an easy task to choose a right PDM solution for a particular company. A major purpose of this paper is to provide essential factors in evaluating PDM systems. While developing the factors. we consider the expected future trend of PDM technologies and three types of PDM-based intergration (frontward, rearward, and sideward integrations). We Propose to carry out the evaluation process in two fold. An overall evaluation is performed first to narrow down many alternatives into a few candidate systems, and then a detailed technical evaluation step follows to determine the final solution. A number of influencing factors are categorized and described in each of these steps.

Although various criteria on the diagnosis of diabetic neuropathy are applied from trial to trial, being tailored in concert with its purpose, the utmost evidences of the diagnosis are subjective symptoms and objective signs of neurologic deficit. The application and interpretation of auxiliary electrophysiological test including nerve conduction study (NCS) should be made on the context of clinical pictures. The evaluation of the functions of small, thinly myelinated or unmyelinated nerve fibers has been increasingly stressed recently with the advent of newer techniques, e.g., measurement of intraepidermal fiber density, quantitative sensory testing, and autonomic function test. And the studies with those techniques have shed light to the nature of the evolution of diabetic neuropathy. The practical application of these techniques to the diagnosis of diabetic neuropathy in the individual patients, however, should be made cautiously due to several shortcomings: limited accessibility, wide overlapping zone between norm and abnormality with resultant unsatisfactory sensitivity and specificity, difficulty in performing subsequent tests, unproven quantitative correlation with clinical deficit, and invasiveness of some technique. NCS, as an extension of clinical examination, is still the most reliable electrophysiological test in evaluating neuropathy and gives the invaluable information about the nature of neuropathy, whereas the newer techniques need more refinement of the procedure and interpretation, and the accumulation of large scaled data of application to be considered as established diagnostic tools of peripheral neuropathy.

The objective of this article, positively recognizing existing researches, is to revisit some aspects regarding the Vāstupuruṣamaṇḍala with a square grid work which is a fundamental planning guideline to control the construction of a Hindu temple and a mathematical doctrine to lead ritual programs. Hence, this paper suggests some reservations as to certain details such as temple constructions. In order to lay hold on its meaning, this paper touches upon the specific matters about the Vāstupuruṣamaṇḍala in the building construction of Hindu temples, which set out to shed light on four concerns; first, it explores the formation process of the Vāstupuruṣamaṇḍala in concert with the evolution of Hindu temples over time; second, it considers differences and similarities in comparison with other texts intimately articulated with the construction of temples, and then understands the relationship between their local languages and applications to the Vāstupuruṣamaṇḍala; third, it examines the symbolic and sanctified process of the temple's construction on the Vāstupuruṣamaṇḍala grids with two- or three-dimensional computer graphics (by means of the Auto Cad and Rhino tools), invisibly situating the divinities within it and illuminating the roles of ornamentation in the structural terms of temples; fourth, it presents that there are another rules on the building construction based upon architect-priest's craftsmanship skilled as a stonemason or a carpenter in the manual processes of the temples' construction for proper measurements and truncations of stone and wood closely linked together structural stability of completed temples. In conclusion, proceeding from what has been said above, this thesis shows that the Vāstupuruṣamaṇḍala grid includes both practical and spiritual meanings to construct a Hindu temple.
