Background: Guidelines for esophagogastroduodenoscopy (EGD) in the West allow the continued use of warfarin under therapeutic international normalized ratio (INR) level. In Korea, no guidelines have been issued regarding warfarin treatment before EGD. The authors surveyed Korean cardiac surgeons about how Korean cardiac surgeons handle warfarin therapy before EGD using a questionnaire. Participants were requested to make decisions regarding the continuation of warfarin therapy in two hypothetical cases. Methods: The questionnaire was administered to cardiac surgeons and consisted of eight questions, including two case scenarios. Results: Thirty- six cardiac surgeons at 28 hospitals participated in the survey, and 52.7% of the participants chose to stop warfarin before EGD in aortic valve replacement patients without risk factors for thromboembolism. When the patient's INR level was 2, 31% of the participants indicated that they would choose to continue warfarin therapy. For EGD with biopsy, 72.2% of the participants chose warfarin withdrawal, and 25% of the participants chose heparin replacement. In mitral valve replacement patients, 47.2% of the participants chose to discontinue warfarin, and 22.2% of the participants chose heparin replacement. For EGD with biopsy in patients with a mitral valve replacement, 58.3% of the participants chose to stop warfarin, and 41.7% of the participants chose heparin replacement. Conclusion: This study demonstrated that attitudes regarding warfarin treatment for EGD are very different among Korean surgeons. Guidelines specific to the Korean population are required.

The current study examined 3- and 4-year-olds' affective decision-making in a variety of cultural contexts by comparing European Canadian children to Chinese Canadian, Hong Kong Chinese, and mainland Chinese children (N = 245). All children were tested with a delay of gratification task in which children chose between an immediate reward of lower value and a delayed reward of higher value. Results showed that Chinese Canadian and Hong Kong Chinese children chose more delayed rewards than European Canadian children, with mainland Chinese children showing a trend toward more delayed rewards. Across cultures, 4-year-olds chose more delayed rewards than 3-year-olds; and among 4-year-olds, girls made more such choices than boys. The findings are consistent with previous findings that exposure to Chinese culture is associated with better cool executive function, but they also highlight the importance of examining development across diverse cultural contexts.

The Plan for effective usage of living room must be suggested because families primarily use living room for public space. And from the viewpoint of function and decoration. the kind of furniture. furniture occupancy quantity. and the arrangement of furniture have much affect on using a dwelling space. So this study will suggest basic data for a good furniture usage through experiment using scale down models. To analyze the data. frequency and percentage were used by running SPSS $PC^＋$ program. The major results are as follows. In an experiment using living room and furniture models(Scale 1/20). according to the size of space. TV sizes and furniture occupancy quantity were in proportion to size and space of the living room. Also they chose various types of tea-table and side-tables. In small spaces. subjects chose simple arrangement types (no sofa or I type sofa and cabinet). but in large spaces. they chose \ulcorner type or \ulcorner type sofa and cabinet.

In this study we analyzed the relationship between sensibility image and the needs to purchase, by studying the relations between the brand name of the beer which consumers recognize and the needs to purchase, and by extracting the sensibility image from the consumers about how they feel about the advertisement. For the survey we first chose 30 sensibility related adjectives from the preliminary survey and chose the 6 most selected sensibility related adjectives by showing beer advertisements from the 3 leading companies. In the main survey we used 7 point scale measurement to evaluate the sensibility scale in each advertisement using the 6 sensibility related adjectives we chose from the preliminary survey, such as cleanness, coolness, pleasantness, softness, easiness, and studied why they feel that way about the advertisement. We hope to contribute on establishing the advertising strategy of the company, based on sensibility image which the consumers are in favor of.

In this paper, we present a method which can minimize distortion from desired signal in thoracic sound signal processing. We firstly chose the proper wavelet mother function to reduce noise components. Secondly, we chose a clean thoracic sound, then added Gaussian noise and 3 step(10, 15, 20db) uniform noise to it. Finally, the various wavelet functions are applied for noise cancellation. To evaluate the efficiency of this study, we computed SNR and RSE value. Then we found the optimal mother wavelet function for thoracic sound.

This study is to examine personal color - preferred color, well-matched color and the relations between preferred color and the well-matched color. Focus is also placed on how sexual difference influences color temperature preference. For data collection, a questionnaire including color stimulus was employed. The subjects of this study were the male and female college students who lived in Pusan. The results of the research are summarized as the following : In view of preferred color, male subjects preferred KEY2 color(warm) in red, pink, and yellow, and preferred KEY1(cool) in green and blue. While most subjects showed the same signal, in green, male preferred KEY1 color and female preferred KEY2 color. Concerning preferred personal color type, KEY1 type person liked KEY1 color except red, and KEY2 type person liked KEY2 color except blue. This shows that people prefer the focused color presenting its own traits. In view of well-matched color, most subjects liked KEY2 color in red, yellow, pink, and they selected KEY1 color in blue as the well-matched color. However, in green, each sex showed different preferences; while male subjects selected KEY1 color as the well-matched color, female ones selected KEY2 color. In each personal color type, KEY1 type male evaluated KEY1 color as the well-matched color, KEY2 type male evaluated KEY2 color except blue. KEY1 type female chose all the KEY1 color as well-matched colors, and KEY2 type female chose KEY2 color. The well-matched colors are similar between male and female subjects. In over 80 percentage of the answers, the preferred colors coincided with well-matched colors. KEY1 type persons chose KEY1 color, and KEY2 type person chose KEY2 color as the well-matched color. These results show that there is a meaningful relationship between the preferred color and well-matched color.
