Purpose : The purpose of this study was to develop the radiographic technique for detecting the demineralization which is known as indication of dental caries. Materials and Methods : This technique was based on the comparing of multiple radiographs which was irradiated by multiple X-ray spectra. For the meaningful comparing, the multiple radiographs were reconstructed to the dosimetrically consistent images using a standard material. The difference of resulting images of same target with multiple spectra represents the difference of response of material as regards the spectra. Results : We have found about 10% of demineralization of dental hard tissues particularly in the proximal region through the analyzing of differences. Conclusion : Most intriguing thing in this investigation was that the method to analyze difference shows us to an anatomic structure of dental hard tissues even if absolute values of optical density were excluded during the procedures.

I took a good look at general features about sway of Ho-jok(Magnate) in Cheong-ju which had formed the most powerful sphere of influence in the middle of the Korean Peninsula. As a result, I could ascertain that the local public service personal, with Sangdae-deung as the central figure, had extended ruling power after 'the pole of pennant at Yong-du temple' (Yong-du-sa-dang-gan) was made in 962 (the 13th year since King Kwang-jong ascended the throne). And also confirmed that the administrative organization was operating for itself, the name of which similar to the organization at the rearranging period of local position in the province like Cheong-ju. According to the names of the Dong-dang-gan-gi, could look through the formation course of four families. They are; the Kim family in Cehong-ju, the Son family, the Han family and the Kyung family. It seems that thse four familites led the society in Cheong-ju, being on about equal status - but more or less the Kim family was most fowerful. Therefore it may be proper that the Ho-jok in those days had strived for their power as well as for their coexistance and coprosperity. Next, I'd like to say about the development course of these Ho-jok families. Early in the Ko-ryo era, the Ho-jok in Cheong-ju had already formed strong power, but the families which had grown in their provinces became separated from the onews which had got the positions in capital after leaving their places of family origin. Especially the Kim family and the Son family was the such. It is considered that the two families came to obtain government positions by submitting or making united efforts to King Wang-gun at the beginning of Ko-ryo Dynasty. By getting an position as the military nobility for Kyung-jun, the father of Kyung-dae-seung, the Kyung family in Cehong-ju may produced the most distinguished talent under the military regime. But afterwards, the power of the family seemed to fall into decay. Through the study of these four families, I could believe firmly that I came to understandin detail the actual conditions and the local public structure of Ho-jok and the promotion course of the aboriginal families.

Purpose : The purpose of the experiment was to evaluating the diagnostic ability of dental caries detection using digital subtraction in the artificial caries activity model. Materials and Methods : Digital radiographies of five teeth with 8 proximal surfaces were obtained by CCD sensor (Kodak RVG 6100 using a size #2). The digital radiographic images and subtraction images from artificial proximal caries were examined and interpreted. In this study, we proposed novel caries detection method which could diagnose the dental proximal caries from single digital radiographic image. Results : In artificial caries activity model, the range of lesional depth was 572-1,374 μm and the range of lesional area was 36.95-138.52mm². The lesional depth and the area were significantly increased with demineralization time (p<0.001). Furthermore, the proximal caries detection using digital subtraction radiography showed high detection rate compared to the proximal caries examination using simple digital radiograph. Conclusion : The results demonstrated that the digital subtraction radiography from single radiographic image of artificial caries was highly efficient in the detection of dental caries compared to the data from simple digital radiograph.

This study was performed to evaluate the effectiveness of a nutrition education program developed for nutritionally imbalanced adolescents. A summer nutrition camp was held for 23 overweight and 16 underweight subjects. Its effectiveness with regard to was evaluated at the end of the camp and 6 months later. Nutrition knowledge, nutritional attitude, food behavior, nutrient intake, exercise habit and ideal body figures desired by the subjects. The results showed significantly higher nutrition knowledge scores at the end of the camp as compared to those obtained prior to the camp program, and these scores were maintained for at least six months. Nutrition attitude scores also improved after the education program, and these improved scores also lasted for 6 months. However, the food behavior scores measured 6 months after the education program were not significantly different from those obtained prior to the camp. Also, the exercise habit, the ideal body figures and the body figures desired by the subjects remained unchanged. When nutrient intakes of subjects were assessed before the program and 6 months later, the mean daily vitamin C intake was significantly increased after the education program. Also, the intake of iron from plant food sources increased in the overweight subjects, while less iron from animal source were consumed by the underweight subjects. Both groups tended to consume more vegetables and fruits 6 months after the education program which may have contribute to the higher vitamin C and plant-based iron intakes. These results indicate that a 4-day nutrition education camp program sustained changes in nutrition knowledge and nutrition attitude for 6 months. The increased intake of vegetables and fruits was also achieved through this education program. However, changes in dietary behavior in adolescents may require repeated education.

The general trends observed in the history studies published in the post era of the Chosun dynasty will be generally divided into two branches. The one is to elevate the status of Dangoon(檀君) upto the founder of the nation, and then describe him God and Human later. The other is to write the history by emphasizing Gija(箕子) traditions and thoughts-legitimacy and public justice etc., and also strongly reflecting Confucian rationality. Dong sa(東史) by Soosan(修山) will be categorized into the former one mainly focused on Dangoon(檀君). Even though Dong Sa(東史) is not satisfying all the conditions required for a complete history book, the reason it has been brought to our attention is its broad recognition of the ancient history. The publication of Dong Sa(東史) has been a notable step in the direction for keeping ancient history researches going by preventing destruction of historical records and loss as well. It seems to me that the distinct contribution of Dong Sa(東史) to national history studies is to bring close attention to Balhae(渤海) and understand it in the context of the national history. As mentioned previously, even though Soosan's(修山) attitude in history understanding is not enough to wash Confucian limitation away from the study, Soosan(修山) stands out in his subjectivity in the study of the national hestory turning subversive relation between Korea and China as it had been into that of equality. Soosan's(修山) arguments not only built up the foundation of Silhak School(實學派) for its attitude toward history but also gave significant impacts on nationalistic historians. In conclusion, Soosan's(修山) way of history recognition was a notable attempt to explain Korean history on a subjective point of view, and subsequently provided turning point for the explanation of Korean history.

This study was designed to develop and test a structural model for the burden in families with the prolonged schizophrenia. The model included 6 theoretical concepts and llpaths. The data were collected from May to July, 2002. The subjects of this study were Mx) families with the prolonged schizophrenia registered in four community mental health centers at Daegu city. An SPSS PC+ and PC-Lisrel 8.30 computer programs were used for descriptive an covariance structure analysis. The results of the study were as follows: 1) The hypothetical model showed itself a good fit to the empirical data. Goodness of Fit Index = .980 Ajusted Goodness of Fit Index = .908 GFI=.980, AGFI=.908 NFI=0.913 2) The results of hypthesis testing indicated that five paths were significant.
