This study was investigated the effects of various system parameters on the absorption of carbon dioxide into absorption solution. An aqueous potassium carbonate solution was used as a chemical absorbent in order to figure out the effect of chemical reaction. For this purpose, the chemical analysis of potassium carbonate solution was performed. The changes of pressure, temperature, K₂CO₃solution flow/feed gas ratio and solution concentration in the absorber and the changes of pressure and temperature in the stripper were also analyzed. The analysis result shows that K₂CO₃ concentration in potassium carbonate solution was 99.6%. The optimum pressure was found to be 27.0㎏/㎠ and the optimum temperature was to be 68℃, the optimum concentration of potassium carbonate solution was to be 26.0wt% in the absorber. The CO₂ leakage decreased with the increment of the K₂CO₃ solution flow/feed gas ratio. But the H₂ leakage in the CO₂ product increased at or above the K₂CO₃ solution flow/feed gas ratio of 1.10. This H₂ leakage induced by the loss of ammonia production. The effects of the changes of the operation condition of the CO₂ stripper to the K₂CO₃ conversion are as follows. The K₂CO₃ conversion decreased as the pressure decreased. The K₂CO₃ conversion increased as the temperature increased. However, increasing the temperature without decreasing the pressure did not bring positive effect. The optimum pressure was found to be 0.45㎏/㎠.

A 12-year-old, female miniature pinscher dog with history of fever and vaginal discharge 3 days ago was referred to the Veterinary Medical Teaching Hospital of Chungnam National University. A diagnosis of pyometra was made by survey of abdominal radiographs and ultrasonography. The uterus appeared as convoluted and tubular appearance filled with anechoic to hypoechoic fluid. Ovariohysterectomy was the choice of cervical patency. Medical therapy for pyometra may be appropriate in bitches that were of breeding age and that were not systemically ill. The surgery was fine. After 1 week, the dog was getting better.

For retrospective study of canine pyoderma in 45 cases diagnosed at Chungnam National University Veterinary Medical Teaching Hospital between January 2004 and October 2006, incidences of cause, sex, breed, age, season, food, lesional skin and environment was compared. Forty-five dogs were included in this retrospective study. The incidence of canine pyoderma in dermatology cases was 56%(45/80). The mean age of the 45 dogs was 4.89 years. There were 20 males and 25 female. Shunauzer and American Cocker spaniel appeared to be at higher risk of developing canine pyoderma than were other breeds. Distribution of lesions were highly variable. Some dogs in this study(21/45) had underlying diseases, including acute trauma(n=6), allergy dermatitis(5), seborrheic dermatitis(n=4). Recurrence of canine pyoderma was high.

The study analyzes a series of decisions made by Building Construction Review Committee on public building construction project. Several government authorities are engaged on the review and required the building client authority to revise the design according to revise items suggested by the committee members ranging from Architectural Planning to other Building Engineering fields. The study delves the legal and design aspects of the review, the meaning of private, semi-public and public function of building, and the construction policy. Two Public building projects were analyzed in terms of revise items. We found some patterns of problem and the current review system works to promote technical aspect of the building and to keep public entity of the projects.

An eleven year old castrated male Maltese was presented to the Veterinary Medical Teaching Hospital of Chungnam National University. In physical examination, approximately 0.5 cm round mass was observed on tail base. This small elevated mass has also shown alopecic and firm configuration. It was differentially diagnosed as sebaceous adenoma and hyperplasia by fine needle aspiration. After surgical removal, the sample was diagnosed as sebaceous hyperplasia by histopathological examination. It has not yet shown any signs of recurrence and prognosis has teen good.

Purpose : This study investigated the prevalence of middle school students with ADHD and the level of middle school teacher's knowledge, coping strategies, and educational intervention for ADHD. Methods : There were 185 teachers and 6,381 middle school students at the 6 middle schools in Pusan. The data was collected from December 20, 2003 to January 10, 2004. Results : 195 middle school students had ADHD (3.1%). The male students with ADHD made up 4.4% of the total students and the female students with ADHD totaled 1.3%. The mean score of middle school teacher's knowledge about ADHD was 21.86 of the score total 32. The teachers used a negative coping style less than an active and passive coping style. Of the educational interventions, the environmental intervention in the classroom was used more than the educational intervention activity. 61.1% of the teachers responded that they did not know very much about ADHD. 93.5% of the teachers had no educational experience with ADHD. 94.1% felt that they needed an education program about ADHD and over half of them intended to participate in an ADHD education program. Conclusion : Based on the results of this study, we concluded that the middle school teachers felt that they had insufficient knowledge about ADHD. They wanted the opportunity to increase their knowledge of ADHD. Therefore, it is necessary for educational programs about ADHD for teachers to be developed and made available to them.

Mondor's disease is a rare disorder characterized by superficial thrombophlebitis and usually develop in thoracoabdominal wall. It has clinical feature of sudden development of painful cordlike structure. The cause is not determined in about 50-60% but it is suggested that trauma, surgery, exercise, drug abuse are often associated. A 44-year-old woman presented cordlike linear tender lesion on right thoracoabdominal wall and histopathologic examination revealed thrombophlebitis with organized thrombus.
