Purpose: As a cultural descriptive research, this study investigates the joys and sorrows that mothers who have been taking care of a child with mental illness in the Korean culture. Methods: The data were collected from June 2011 to July 2012 targeting a total of 11 mothers who were looking after chldren with mental illness in their own places. Recorded and transcribed data though in-depth interviews were analyzed by Spradley's classification and analysis method. Results: The joys and sorrows of the mothers focused on the cultural topic, "social sense of isolation', and the joys and sorrows were confirmed to be 'fury to reality', 'despair of illness', 'blame on family', 'remorse for the life' and 'little pleasure earned by emptying mind'. Conclusion: It is suggestive that the results of this study can be used to understand the joys and sorrows of the mothers with the mental patients; may be used to improve sociocultural understanding of the mothers; and may be applied to nursing practice.

The purposes of the study are to design a key-frame extraction algorithm for constructing the virtual storyboard surrogates and to evaluate the efficiency of the proposed algorithm. To do this, first, the theoretical framework was built by conducting two tasks. One is to investigate the previous studies on relevance and image recognition and classification. Second is to conduct an experiment in order to identify their frames recognition pattern of 20 participants. As a result, the key-frame extraction algorithm was constructed. Then the efficiency of proposed algorithm(hybrid method) was evaluated by conducting an experiment using 42 participants. In the experiment, the proposed algorithm was compared to the random method where key-frames were extracted simply at an interval of few seconds(or minutes) in terms of accuracy in summarizing or indexing a video. Finally, ways to utilize the proposed algorithm in digital libraries and Internet environment were suggested.

In a general fractional factorial design, the n-levels of a factor are coded by the $n^{th}$ roots of the unity. Pistone and Rogantin (2007) gave a full generalization to mixed-level designs of the theory of the polynomial indicator function using this device. This article discusses the optimal blocking scheme for nonregular designs. According to hierarchical principle, the minimum aberration (MA) has been used as an important criterion for selecting blocked regular fractional factorial designs. MA criterion is mainly based on the defining contrast groups, which only exist for regular designs but not for nonregular designs. Recently, Cheng et al. (2004) adapted the generalized (G)-MA criterion discussed by Tang and Deng (1999) in studying $2^p$ optimal blocking scheme for nonregular factorial designs. The approach is based on the method of replacement by assigning $2^p$ blocks the distinct level combinations in the column with different blocks. However, when blocking level is not a power of two, we have no clue yet in any sense. As an example, suppose we experiment during 3 days for 12-run Plackett-Burman design. How can we arrange the 12-runs into the three blocks? To solve the problem, we apply G-MA criterion to nonregular mixed-level blocked scheme via the mixed-level indicator function and give an answer for the question.

In this paper, a novel gray-scale lossless image coder combining context-based minimum mean squared error (MMSE) prediction and entropy coding is proposed. To obtain context of prediction, this paper first defines directional difference according to sharpness of edge and gradients of localities of image data. Classification of 4 directional differences forms“geometry context”model which characterizes two-dimensional general image behaviors such as directional edge region, smooth region or texture. Based on this context model, adaptive DPCM prediction coefficients are calculated in MMSE sense and the prediction is performed. The MMSE method on context-by-context basis is more in accord with minimum entropy condition, which is one of the major objectives of the predictive coding. In entropy coding stage, context modeling method also gives useful performance. To reduce the statistical redundancy of the residual image, many contexts are preset to take full advantage of conditional probability in entropy coding and merged into small number of context in efficient way for complexity reduction. The proposed lossless coding scheme slightly outperforms the CALIC, which is the state-of-the-art, in compression ratio.

In Korean terminologies, adjectival terms are rare, and the meaning and function associated with adjectives in Indo-European languages are often realized instead in noun form. However, the rarer adjectival terms we, the more they are used in restrictive and repetitive ways in specialized domains. Thus, it is important to distinguish the different senses of these terms. In this work, focusing on semantic modeling in terminology, we distinguish the different senses of adjectival medical terms by applying lexico-semantic criteria (L'Homme, 2004a) and by classifying the semantic category of the arguments of the adjective (Bae and others, 2002). The result not only contributes to enriching medical terminology, but also empirically demonstrates a method for distinguishing the different senses of adjectival medical terms. In this work, we obtained an average of 1.854 senses for each term. We used the KAIST corpus, composed of medical texts (1,500,000 eojeols), and a group of texts on various subjects (40,000,000 eojeols)

At the turn of the century in which European colonialism was reaching its zenith and modernization was gathering speed, public museums were institutionalized. This paper looks into the part these European modern museums played in territorializing academic disciplines like anthropology and art history. The museums to deal with are the British Museum and the National Gallery in London, Mus?e du Louvre in Paris, and Museumsinsel in Berlin. Rather than in-depth detailed analysis of each museum, the aim is to explore the ways in which these museological institutions interacting with modern disciplines in the wider colonial context objectified other cultures and formulated a framework of the world through classification and comparison of material things, on the basis of the judgement of their artistic values. This exploration is also to rethink theoretical positions and perspectives on the museum in Korea. It is remarkable in Europe that such academic fields as history, art history, anthropology and cultural studies look for new possibilities of museology in conjunction with the recent proliferation of studies on the museum as a medium to construct and deconstruct knowledge. Meanwhile, the mammoth European museums which are often considered a stronghold of museology advocate the 'universal museum' themselves, quite the modern idea but in a revised rendering. Under these circumstances, this paper seeks to shed light on the definition of the museum as an arena in which scholarly discourses about art, culture and history can be created and contested, on the effectiveness of the museum as a communication medium in a postcolonial era, and on the need to pay trans-disciplinary attention to the museum in its broadest sense.

Global fashion houses have recently incorporated traditional Korean motifs within their inspiration. This trend is an opportunity to showcase the colors of traditional Korean culture by investing in the new design content. Products specifically based on traditional Korean culture are lacking in brand awareness despite the success of Korean content. Accordingly, this study designs cultural products based on Korean folk painting that captures Korean people's satirical sense of humor. Korean folk painting theories are analyzed, from which different types of folk paintings are classified based on research of bibliographies and online documents. Following classification, the results are dataized as different types of folk paintings and their meanings. Furthermore, images of folk paintings are categorized and scanned digitally. The digitized images of the folk paintings are processed through Adobe Photoshop CS for overall layout and Adobe Illustrator CS for detailed designs. Traditional categories of Korean folk paintings are used, including flowers and birds, letters, and study stationery. Using the main elements of the flower and birds category, designs with cultural products such as images of flowers, birds, animals, and fish are produced. The final designs are used to create fashion items that can easily be used for embellishment or self-presentation: a scarf and a necktie. The scarf and the necktie are not only merchandise; they also symbolize the story, humor, and hope that Korean folk paintings once symbolized.

In this study, we have proposed an estimation model of domestic market size using the linking between standard statistical classification systems, and reviewed the practical applicability of the model. The results of the mining and manufacturing survey of Statistics Korea conducted on the basis of KSIC (Korea Standard Industrial Classification) and Korea trade statistics based on HS (The Harmonized Commodity Description and Coding System; Harmonized System) classification were linked for the model by using the correspondence tables provided by Statistics Korea and United Nations Statistics Division. The most serious problem to adopt the integrated KSIC-ISIC-HS correspondence table for the estimation of domestic market size is the complex multiple linkages among KSIC and HS codes. In this study, we have suggested the method to divide the amount of trade corresponding to the HS codes linked to more than two ISIC codes based on the ratio of shipments corresponding to the ISIC codes as the weight. Then, it is possible to analyze the domestic market size of 125 ISIC codes in the manufacturing industry and to forecast the market size in the near future by using the model. Although the model has some limitations such as the difficulty in analysis on more subdivided items than ISIC items, the impossibility of the analysis on items in industries except for manufacturing, errors in the shipment due to some missing data, this study has significance in the sense that it provided the analysis method of domestic market size by using the most objective, reliable and sustainably useful data.

Purpose: To determine the clinical value of the Siewert classification for gastic-cancer patients in Korea, we evaluated and compared the clinicopathologic factors of type II and type III cancer. Materials and Methods: The medical records of 89 consecutive patients who had undergone surgery for an adenocarcinoma of the gastroesophageal junction (GEJ) at the Department of Surgery, Hanyang University Hospital, between Jun. 1992 and Dec. 2003 were reviewed retrospectively. Results: There were one patient with type I, 12 pateints with type II and 77 patients with type III. During the same period, 1,341 patients underwent surgery for a gastric carcinoma, so proportion of GEJ cancer being $6.6\%$. The median followup duration was 31 months (range: $2\∼135$ months), and the follow-up rate was $100\%$. Between type II and type III cancers, there were no significant differences in the clinicopathologic variables including age, sex, gross appearance, histologic type, depth of invasion, and pathologic stage. The longest diameter of the tumor was larger in type III ($6.1\pm2.1$ cm) than in type II ($3.9\pm1.1$ cm)(P=0.001). A total gastrectomy with Roux-en-Y esophagojejunostomy was done most frequently, while jejunal interposition was done in 3 cases of type II and 2 cases of type III. More than a D2 lymphadenectomy was done all cases. The numbers of dissected lymph nodes and metastatic lymph nodes in type II were 43.8 and 5.8 respectively, while they were 49.8 and 8.1 in type III, but the difference between the two groups were not statistically significant. The mean length of the proximal resection margin was $15\pm5$ mm in type II and $21\pm13$ mm in type III, but this difference was not statistically significanct. The time to recurrence after operation was 19.3 months in type II and 16.9 months in type III. The five-year survival rates of type II and III were $68.8\%\;and\;52.7\%$ respectively, but difference was not significant. Conclusion: There were no significant differences in the clinicopathologic variables, including survival rate, between type II and type III cancers in Korean patients According to these findings, it appears to be reasonable to classify type III cancer as a cardia cancer in a broad sense.
