The purpose of this study were to develop a smoking preventive education program for elementary students and evaluate it's effectiveness. This study was a quasi experimental study under the nonequivalent control group with pretest-posttest design. The subjects of this study were 62 who are attending elementary school(31 for each group), 2 different district elementary school. The subjects were matched by grade, similar in anti-smoking educational background of smoking, as well as their residence and income level of their families. The instruments used in this study was 18 criterion referenced test items modeled by Dick & Carey that were developed by researchers for evaluating the subjects' knowledge and attitude about smoking. A pretest was administered a week before treatment The program given to the experimental group is composed of the texts explaining the poisonous substances in tobacco, social and cultural harmfulness of smoking to the body and psychology, indirect smoking, smoking of pregnant women, motives of smoking, refusal skills of smoking; and for the subjects' understanding and the better results of study - pictures, role play, discussion, text through computer based multi-media, puzzle searching for hidden pictures, cross-word puzzle, and finally compensation. The data were collected for 50 days form mid- September to the end of October in the year of 2000, composed of formative evaluation, pre-test and summative evaluation via 2 sessions. Accordingly, the collected data were analysed by t-test, paired t-test, repeated measure ANOVA by the SAS program. This research summarize the findings as follows; 1. There was a significant difference in knowledge between the experimental group(after 1 wks t=10.4680, p=.0001; after 4 wks t= 9.310, p=.0001) and control group(after 1 wks t=0.0420, p= .9669; after 4 wks t= -0.378 p=.7079) in between the results of 1 and 4 week after education in summative evaluation (F=27.45, P=.0001). 2. There was non statistical significant difference in attitude between the experimental group (after 1 wks t=1.2292, p=0.2286 ; after 4 wks t=1.330, p=0.1935) and control group (after 1 wks t=0.1819, p=0.8569 ; after 4 wks t=0.2970, p=0.7685) in between the results of 1 and 4 week after education in summative evaluation(F=0.71, P=0.494). To sum up, the statistics of conclusive analysis evaluative for the children under school age of the 'knowledge acquisition' about smoking harmfulness. On the other hand, as there was already sound attitude about smoking, the evaluation of attitude was non significant difference between control group and experimental group, just there was partially significant difference.

In this paper, we study a model parameter compensation method for noise-robust speech recognition. We study model parameter compensation on a sentence by sentence and no other informations are used. Parallel model combination(PMC), well known as a model parameter compensation algorithm, is implemented and used for a reference of performance comparision. We also propose a modified PMC method which tunes model parameter with an association factor that controls average variability of gaussian mixtures and variability of single gaussian mixture per state for more robust modeling. We obtain a re-estimation solution of environmental variables based on the expectation-maximization(EM) algorithm in the cepstral domain. To evaluate the performance of the model compensation methods, we perform experiments on speaker-independent isolated word recognition. Noise sources used are white gaussian and driving car noise. To get corrupted speech we added noise to clean speech at various signal-to-noise ratio(SNR). We use noise mean and variance modeled by 3 frame noise data. Experimental result of the VTS approach is superior to other methods. The scheme of the zero order VTS approach is similar to the modified PMC method in adapting mean vector only. But, the recognition rate of the Zero order VTS approach is higher than PMC and modified PMC method based on log-normal approximation.

Saseol Sijo which reflects on people's life often showns us relationships between love and economy of those periods' people in Chosun dynasty. Meaning of a word 'housewife' is a woman who supporting and organizing family with her husband. Materialistic problems and economic problems appeared in Saseol Sijo emphasize entertaining and merrymaking rather than struggling to the society enforcing poverty. Therefore, it is often said that Saseol Sijo stimulates overconsumption of goods and money. We can regard sexual discussions appeared in those periods' Saseol Sijo as reflections of desire which are the way of releasing repressed sexual appetite of women or substitutions of satisfying their sexual appetite. Features of housewives appeared in Poong-ryu-bang and Saseol Sijo which are succeeded as productions of merrymaking in Latter half period of Chosun dynasty, can spotlight because of its meanings. It told us not only housewives' roles are started to change but also vivid sexual discussions similar to nowadays things are begun in latter half Period of Chosun dynasty. Main subject pecuniary mediated sexual discussion of housewives appeared in Saseol Sijo teaches a lot of things to twenty first century's contemporary people experiencing collapsed family relationship, pariakapitalismus and wide spread sexual industries.

In this study, we have examined how the potential users of IT convergence product use the external information sources for purchasing decision focusing on a case of smartphone. Although the specifications and price of IT convergence products, such as smartphone, tablet pc, and smart TV, are considered as major criteria for purchasing decision, the competitiveness of these factors have disappeared as many companies launch similar products in the market. External information sources play a significant role to differentiate the alternatives by offering value-added experience information. The effect of external information sources becomes stronger for experience and high-involvement product whose performance can be evaluated through only users' direct experience. In this study, we categorized the external information sources for smartphone into five; company ads, personal network, expert group, consumers, and media. Through an empirical study with potential smartphone users, we verified how these external information sources affect users' purchasing decision in the perspective of the perceived attributes of information source, quality of information, and individual's characteristics based on self-regulatory theory.

The purpose of this study is to recognize the aesthetic characteristics of the Maximalism depicted in contemporary costumes of new millennium. This is done by analyzing and examining the social and cultural background of fashion in the few years of 21st century. The fashion trend of the beginning of 21st century was coexisted conflicting factors with ultramodern factor and past recurrent factor. For that reason, new millennium is to be existence background of Maximalism style in contemporary costumes. The social and cultural background of Maximalism was regarded as characteristics of the Glocalism, fusion style, bobos. Glocalism means a compound word of Globalism and Localism, and used various fields of policy, economics, society etc. Consequently, the aesthetic formativeness of Maximalism of the contemporary costumes was investigated as the 'Romantic Hippie Look' and 'Romantic Sports Look' 1) Romantic Hippie Look New millennium fashion trend is affected by hippie style of 1970's. That is major reason that the antiwar consciousness of 9.11 terror, USA-Afganistan war and the economic depression is similar to 1970's situation. Accordingly, fashion trend is developed into bright, light, romantic style and fashion designers chose materials with flowers, butterflies, dragonflies pattern. Because the clothing of these material reflects well modern people's feeling to escape misgivings, unrest of political terror, war etc. The characteristics of hippie style expressed freedom as the greatest merit was raised new trend, so called 'Romantic Hippie Look' on new millennium. That is, the romantic hippie look of the contemporary costumes is depicted as the formative beauty of the multiculturalism and nationalism. 2) Romantic Sports Look : The beginning of new millennium, many fashion designers intend to graft the details of sports wear on order made or ready made clothing and try to show luxury and cheerful fashion design with combination of sporty and romantic factors. Accordingly, theses fashion trends expressed 'Romantic Sports Look' with a harmony or disharmony of unusual factors. The fashion trend of new millennium centering around special cities like New York, Paris, Milan moved to various regional culture. Accordingly, the features of fashion depicted not unique theme but multiplicity of the clothing of dissimilar style or material by the mixture of 2 or 3 factors like the fusion of femininity and masculinity and the combination of past and present of details. That is, the romantic sports look of the contemporary costumes is depicted as the formative beauty of the multi-functional and crossover.

Background: The word "geop" is a unique Korean term commonly used to describe fright, fear and anxiety, and similar concepts. The purpose of this pilot study is to examine the correlation between the Numeric Rating Scale (NRS) score of geop and three different questionnaires on pain perception. Methods: Patients aged 20 to 70 years who visited our outpatient pain clinics were evaluated. They were requested to rate the NRS score (range: 0-100) if they felt geop. Next, they completed questionnaires on pain perception, in this case the Korean version of the Pain Sensitivity Questionnaire (PSQ), the Pain Catastrophizing Scale (PCS), and the Pain Anxiety Symptoms Scale (PASS). The correlations among each variable were evaluated by statistical analyses. Results: There was no statistically significant correlation between the NRS score of geop and the PSQ score (r = 0.075, P = 0.5605). The NRS score of geop showed a significant correlation with the PCS total score (r = 0.346, P = 0.0063). Among the sub-scales, Rumination (r = 0.338, P = 0.0077) and Magnification (r = 0.343, P = 0.0069) were correlated with the NRS score of geop. In addition, the NRS score of geop showed a significant correlation with the PASS total score (r = 0.475, P = 0.0001). The cognitive (r = 0.473, P = 0.0002) and fear factors (r = 0.349, P = 0.0063) also showed significant correlations with the NRS score of geop. Conclusions: This study marks the first attempt to introduce the concept of "geop". The NRS score of geop showed a moderate positive correlation with the total PCS and PASS score. However, further investigations are required before the "geop" concept can be used practically in clinical fields.

Korea introduced the cooperation charge on conservation of ecosystem for minimizing damage of ecosystem due to development projects and their effects and for preparing resources for natural environment conservation projects. Advanced countries have made efforts by expanding investment in natural environment conservation and restoring projects to promote prevention of global warming and improvement of biological diversity, are establishing nationwide strategies and plans. To examine the reality of projects by returns of the cooperation charge on conservation of ecosystem, microsite projects in schools and public facilities take the largest share while their project budgets are only about 100~300 KRW, relatively small, which might be attributable to budget restrictions in accordance with the calculating method of levying cooperation charge on conservation of ecosystem and problems of project proceeding in the system of returning fund for projects in general. The conclusion which this study suggests on invigoration of cooperation charge on conservation of ecosystem and its operation are as followings. First, although the cooperation charge on conservation of ecosystem has been introduced in 2001, the amount of imposition per unit area remains unchanged. It is desirable to increase the amount into $1,400KRW/m^2$ as of August, 2011 as the price index has been continuously rising for the past 10 years and the upward adjustment of imposition per unit area should be notified by the decree of the Ministry of Environment every January. Second, the ceiling amount of the cooperation charge on conservation of ecosystem should be abolished. Now the ceiling amount is defined as 1 billion KRW but it was found that there was not any ceiling amount specified according to the comparative analysis of similar systems with the Korean environmental improvement fund. The ceiling should be abolished so that medium level businesses are carried out and ecosystem recovering projects in the true sense of the word can be made smoothly. Third, weight should be introduced in calculating amounts in accordance with ecologic and economic values. Harmony between development and environment can be achieved by applying differentiated weights of constant regional coefficient by use zone and ecologic and economic values. Continuous efforts of improving cooperation charge on conservation of ecosystem should be made more than anything else so that projects by returns of cooperation charge on conservation of ecosystem get effectiveness.

Pulmonary blastoma is a primary lung tumor consisting of a mixture of immature embryonal-like mensenchymal and epithelial components and in some areas resemble embryonal lung tissue of up to 3-4 months gestational age. The tumor was first described in 1945 by Barren and Barmard and again in 1952 by Barmard, who named it an embryoma of the lung which resembled fetal lung histologically, with glandular structures lined by non-ciliated epithelium and a surrounding stroma resembling mesenchyme. In 1961 Spencer renamed them Pulmonary blastoma as he believed they represented neoplasms similar in pathogenesis to nephroblastoma. The prognosis of these rumors is poor, and the clinical course is not readily predicted from histological appearance. Untill now, more than one hundred cases have been reponed in the literature in the word and there is no report in Korea. We report a case of biphasic pulmonary blastoma, which ruptured spontaneously, in a 31-year-old young man who was presented as sharp pain under the right subscapular area.

In many continuous speech recognition systems based on HMMs, decision tree-based state tying has been used for not only improving the robustness and accuracy of context dependent acoustic modeling but also synthesizing unseen models. To construct the phonetic decision tree, standard method performs one-level pruning using just single Gaussian triphone models. In this paper, two novel approaches, two-level decision tree and multi-mixture decision tree, are proposed to get better performance through more accurate acoustic modeling. Two-level decision tree performs two level pruning for the state tying and the mixture weight tying. Using the second level, the tied states can have different mixture weights based on the similarities in their phonetic contexts. In the second approach, phonetic decision tree continues to be updated with training sequence, mixture splitting and re-estimation. Multi-mixture Gaussian as well as single Gaussian models are used to construct the multi-mixture decision tree. Continuous speech recognition experiment using these approaches on BN-96 and WSJ5k data showed a reduction in word error rate comparing to the standard decision tree based system given similar number of tied states.
