The repair of congenital aural atresia remains one of the most challenging otologic procedures because of the scarcity of surgical landmarks, the complexity and the variety of the temporal bone anatomy, and the limited space for reconstruction. The risks of facial nerve injury and profound sensorineural hearing loss following atresia surgery are common concerns. Furthermore,the rarity of the disease makes it difficult to improve surgical learning. Image-guided surgery may aid otologic surgeons in repairing atresia as it allows identifying the exact position of surgical instruments in relation to the specific anatomy. To our knowledge, there have been no published reports on image-guided atresia surgery in Korea. Herein, we report a case of congenital aural atresia, which was repaired using image-guided surgical technique.

This study provided sorption properties of chlorofluorocarbons (CFCs), and elucidated potential application of CFC sorption data in hydrogeochemistry. Prior sorption studies were reviewed for hydrophobic organic compounds similar to the CFCs, because there were only few CFC sorption studies. The CFCs are regarded as relatively conservative chemicals in groundwater environments based on their moderate hydrophobicity. However, thermally altered carbonaceous matter (TACM) can significantly increase sorption capacity and nonlinearity for hydrophobic organic compounds such as CFCs, compared to general soil organic matter. CFC sorption behavior are close to the sorption for reviewed organic chemicals. Therefore, the CFC sorption data can be used for determining hydrogeochemical properties and predicting transport of organic contaminants in TACM-containing aquifer environments.

Recently, the Go game has been performed between the 'AlphaGo' of the DeepMind and Lee Sedol, a famous professional Go-player of Korea, which leads to arise a lot of interests in the AI (Artificial Intelligence) research area. Based on the Fuzzy logic of the AI, we have also developed another game's AI, .i.e., the Yutnori game, one of Korean traditional board games. However, it is not easy and simple to consider all the cases of the Yutnori game since it is a non-perfect information game in terms of the AI. Thus, we have developed the Fuzzy-logic-based AI which tries to simulate humans' selections, meaning that the suggested AI has focused on the humans' choices depending on diverse situations in the Yutnori. With our extensive simulations using the suggested Yutnori AI, we have analyzed its performances with respect to 10 Yutnori situations among various scenarios. In conclusion, our suggested AI have demonstrated that 6 out of 10 situations are exactly same with the humans' choices and the rest 4 cases are also similar to that of human's, which reveals that our Fuzz-logic-based Yutnori AI can effectively simulate human's choices.

Cleft lip and palate are most common congenital deformity to affect the orofacial region. Cleft lip and palate are caused by abnormal development of primaiy and secondaiy palate. It s causative mechanism is not completely understood, but genetic and envirorunental factors play an important role. Many epidemiologic surveys have been done extensively about incidence, racial influence, sex ratio, parent age, associated syndrome, and genetic factors. These researches are useful to dissolve many problems in prevention and treatment of cleft lip and palate. We performed epidemiologic survey of cleft lip and palate who visited the department of Oral & Maxillofacial surgery, Guro Hospital of Korea University from 1995 to 2001.

Language changes by the flow of time and culture enjoyed. The movie is the genre that can see the appearance changed from the first definition of society. This paper analyzed the title of Japanese movie and Korean movie by period, ranking, use of characters, form and syllables. Even if it is the work of the same times, there is a case that ranking is different. When it comes to the mark, it was used 359times in Korean and 409times in Japan. 'Kanji' was used more for a title in Korea, and 'Katakana' was used for a title in Japan. The frequency of the mark has increased by time in both Korea and Japan. As for a from, one form occupied more than half in Korea by between ranking and period. In Japan, one form increased by ranking. But, two more forms have increased by period. When it comes to a syllable, in Korea, the movie which of the syllable of the title is short tended to have high order. The number of syllables of the title of the movie in Japan was more than that of South Korea. A syllable was short, as for the title of the movie which was high in ranking. On the other hand, the number of syllables of the title of the movie which had low ranking was not constant. A title of 3 syllables is used most in Korean and a title of 7 syllables is used most in Japan by a period. The title of the movie is a thing to express the contents of the movie. To make it easily to remember and catch eye, the change was given to the use of characters of the title and the number of syllables. In conclusion, for success of film, it is better to use about four syllable for the title in Korea, and about ten syllables in Japan. Even though the form of titles have changed and would change by time, it is difficult to write the overall flow of movie only based on information by this investigation. But, the research about the use of characters and syllables of the title seems to be helpful for future's research task.
