In this paper we attempt to read a film by Haejoon LEE entitled 'Castaway on the moon' from the Bauman's modernity perspective that draws our attention to uncomfortable problems relative to wastes and wasted lifes in the global consumer society we all live in. The so-called consumer society is a post-modern society designed according to the following two criteria: on the one hand, beauty and ugliness and on the other hand, competence and incompetence. Classified as ugly as well as incompetent in this society, the two heros in this film are condemned to live their lifes isolated. Miss Kim is confined to her small room while Mr. Kim is exiled to an uninhabited island called 'Bamsum' in the Han River. In these spaces, neither inside nor outside, they perform what we would like to call 'surplus act', using wastes at their disposal. In this paper we ask ourselves whether or not this act is able to challenge the two criteria and the solidarity of the two wasted lifes can bring about change in the consumer oriented society. As well as Bauman, Agamben will help us approach this question from a theoretical point of view.

In this article, I have analyzed the signification of the death of Don Quijote from the oriental religious and philosophical point of view, comparing with the novels of Kim, DongRi. We are able to read Cervantes' hope for his absolute ideal to be lasting forever via the death of Don Quijote, in the base of a strong will named of Gukyeong's life. In the same time, we can also discovery death as lasting of life in the basis of buddhist idea and death as the unification with nature via the meeting between the living and the dead in the Montesinos Cave. Montesinos Cave symbolizes a unclassified and chaotic space, which the Shamanist can meet the dead with a extatic ceremony and both supernatural life and daily life coexist. Therefore, the symbolic death of Don Quijote in Montesinos Cave is abe to be explained by approaching to absolute freedom named of Hatal, in other words, voluntary and conscious death to escape from the yugo of being. Considering the fact that Kim, Dongri emphasized on the unification of sky, earth and human being, keeping a racial identification in the face of the stream of occidental materialism in the time of Japanese conquest, we can look for the similarity with Cervantes' ideal. Contrary to the religious dogmatic ideal, Cervantes treated to recover the human nature and vitality, transcending the occidental rationalism and religious ideology in the time of Counter-reformation.

Purpose - With the rapid development of information technology, the digital economy has become an important grip of the new development pattern, and the digital transformation of enterprises is a major trend. As SMEs are the mainstay of the economy and employment, it is important to study the digital transformation of SMEs to promote the development of the digital economy. Research design, data, and methodology - Based on a resource-based view, this report analyses the current situation and issues of digital transformation of SMEs from the perspective of digital orientation as well as the breadth and depth of technological capabilities of enterprises, using data from a survey of 200 manufacturing enterprises in China. Result - The results show that SMEs generally have a digital transformation mindset, but a weak digital foundation. In order to execute a digital strategy, companies need digital transformation capabilities. These behavioral capabilities are guided by the strategic direction of the business, and companies with strong capabilities are always trying to tap into the full digital potential. Conclusion - In order to effectively promote the digital transformation of SMEs, we suggest that SMEs pay attention to digital capability building, make good use of digital platforms and network resources, and lay a solid foundation for digital transformation; meanwhile, we suggest that government departments play a guiding and supporting role to build a cross-industry and cross-sector digital synergy system to help promote the development of SMEs' digital transformation. This paper presents some suggestions from both the internal and external environment of the enterprise, with the expectation of contributing to the digital transformation practices of SMEs.

The purpose of this study was to investigate the related factors to nutritional supplements intake of elementary school student aged 7 to 12 years in Incheon area. The subjects were 631 mothers of elementary school students and cross-sectional study was conducted by a self-administered questionnaire. In view of the relation with general circumstances, taking nutritional supplements was shown to be significantly associated with general and socio-demographic factors such as father's job, mothers concern about children's academic record, family's monthly income and food cost, and the experience of other family members' taking nutritional supplement. In view of the relation with anthropometric and health-related factors, taking nutritional supplement was associated with elementary school student' weight obesity index, mothers evaluation of children's height and weight mother's concern about health and growth of children, and ,disease of children. In view of the dietary behavior-related factors, taking nutritional supplements was associated with skipping breakfast, food habits, and mothers beliefs and attitude about nutrition and nutritional supplements. However, it was shown that mothers nutritional knowledge did not affect taking nutritional supplements. Therefore, it may be suggested that general and socio-demographic factors, anthropometric and health-related factors, dietary behavior-related factors, and mother's nutritional beliefs and attitude are important determinants in children's taking nutritional supplements.

This paper, which covers a fluorescence microscopy image of brain tumor cells, looks at drug reactions by treating different types and concentrations of drugs on a plate of $24{\times}16$ wells. Due to the limitation of the field of view, a well was taken into 9 field images, and each has an overlapping area with its neighboring fields. To analyze more precisely, image stitching is needed. The basic method is finding a similar area using normalized cross-correlation (NCC). The problem is that some overlapping areas may not have any duplicated cells that help to find the matching point. In addition, the cell objects have similar sizes and shapes, which makes distinguishing them difficult. To avoid calculating similarity between blank areas and roughly distinguishing different cells, thresholding is added. The thresholding method classifies background and cell objects based on fixed thresholds and finds the location of the first seen cell. After getting its location, NCC is used to find the best correlation point. The results are compared with a simple boundary stitched image. Our proposed method stitches images that are connected in a grid form without collision, selecting the best correlation point among areas that contain overlapping cells and ones without it.

The lumbrical muscles contribute to the intrinsic plus position, that is simultaneous metacarpophalangeal (MCP) flexion and interphalangeal (IP) extension. The strength of the lumbrical muscles is necessary for normal hand function. However, there is no objective and efficient method of strength measurement for the lumbrical muscles. In addition, previous studies have not investigated the measurement of the cross-sectional area (CSA) of the lumbrical muscles using ultrasonography (US) and the relationship between lumbrical muscle strength in the intrinsic plus position and the CSA. Therefore, the purpose of this study was to identify the measurement method of the CSA of the lumbrical muscles using US and to examine the relationship between maximal isometric strength and the CSA of lumbrical muscles. Nine healthy males participated in this study. Maximal isometric strength of the second, third, and fourth lumbrical muscles was assessed using a tensiometer in the intrinsic plus position which isolated MCP flexion and IP extension. The CSA of the lumbrical muscles was measured with an US. The US probe was applied on the palmar aspect of the metacarpal head with a transverse view of the hand in resting position. There was no significant difference between maximal isometric strength of the lumbrical muscles, but the fourth lumbrical muscle was stronger than the others. The CSA of the lumbrical muscles was significantly different and the fourth lumbrical muscle was significantly larger than the second lumbrical muscle. There was moderate to good correlation between maximal isometric strength and the CSA of the lumbrical muscles. Therefore, we conclude that maximal isometric strength of the lumbrical muscles was positively correlated to the CSA of the lumbrical muscle in each finger, while the measurement of the CSA of the lumbrical muscles, using US protocol in this study, was useful for measuring the CSA of the lumbrical muscles.

One of the most difficult tasks in measuring oceanic conditions is to produce oceanic current information. In efforts to overcome the difficulties, various attempts have been carried out to estimate the speed and direction of ocean currents by utilizing sequential satellite images. In this study, we have estimated sea surface current vectors to the south of the Korean Peninsula, based on the maximum cross-correlation method by using sequential ocean color images of SeaWiFS chlorophyll-a. Comparison of surface current vectors estimated by this method with the geostrophic current vectors estimated from satellite altimeter data and in-situ ADCP measurements are good in that current speeds are underestimated by about 15% and current directions are show differences of about $36^{\circ}$ compared with previous results. The technique of estimating current vectors based on maximum cross-correlation applied on sequential images of SeaWiFS is promising for the future application of GOCI data for the ocean studies.

Construction of a tunnel induces rock masses damage around the tunnel. The degree of damage produced on rock masses will affect on the mechanical and hydraulic behaviors of the rock masses. In this paper, P wave velocity measured by cross-hole test was used to assess rock masses damage around the test tunnel. Initiation of source signal was carried out using mechanical impact at the source installed borehole. In consequence, the generated P wave signal was low noise and apparent wave form, which allows accurate pick-up of first arrival time. From the test, the region where rock damage is expected shows relatively low P wave velocity. In addition, with multiple points of P wave velocity measurement along each cross-hole, two dimensional P wave tomography was obtained. The tomography provides apparent view of the rock damage behind the tunnel. The measured P wave velocity was correlated with features of rock masses, porosity and Q value.

Purpose: This study assessed the diagnostic performance of stitched and non-stitched cross-sectional cone-beam computed tomography (CBCT) images of non-displaced ovine mandibular fractures. Materials and Methods: In this ex vivo study, non-displaced fractures were artificially created in 10 ovine mandibles (20 hemi-mandibles) using a hammer. The control group comprised 8 hemi-mandibles. The non-displaced fracture lines were oblique or vertical, <0.5 mm wide, 10-20 mm long, and only in the buccal or lingual cortex. Fracture lines in the ramus and posterior mandible were created to be at the interface or borders of the 2 stitched images. CBCT images were obtained from the specimens with an 80 mm×80 mm field of view before and after fracture induction. OnDemand software (Cybermed, Seoul, Korea) was used for stitching the CBCT images. Four observers evaluated 56 (28 stitched and 28 non-stitched) images to detect fracture lines. The diagnostic performance of stitched and non-stitched images was assessed by calculating the area under the receiver operating characteristic curve (AUC). Sensitivity and specificity values were also calculated (alpha=0.05). Results: The AUC was calculated to be 0.862 and 0.825 for the stitched and non-stitched images, respectively (P=0.747). The sensitivity and specificity were 90% and 75% for the non-stitched images and 85% and 87% for the stitched images, respectively. The inter-observer reliability was shown by a Fleiss kappa coefficient of 0.79, indicating good agreement. Conclusion: No significant difference was found in the diagnostic performance of stitched and non-stitched cross-sectional CBCT images of non-displaced fractures of the ovine mandible.
