Objective : Since Korea has been known to be of the endemic area for hepatitis B virus(HBV) infection, vaccination for HBV has been recommended for all neonates in Korea. After starting vaccination in 1983, the change of sero-positivity of HBsAg and HBsAb is expected. This study was carried out to investigate the seropositive rate of hepatitis B virus surface antigen and antibody in high school freshmen students in Chungju-city. Methods and Materials : From 1998 to 2001, a total of 11,735 who were born in 1982 to 1986, were enrolled in this study. HBsAg and anti-HBs were tested by reversed passive hemagglutination and passive hemagglutination, respectively. Results : The study population was 11,735 students who were composed of 5,813 males (49.6%) and 5,914 females (50.4%). The HBsAg sero-positivity of male and female students was 3.25% (n=381) and 2.59% (n=153) respectively. The anti-HBs sero-positivity of male and female students was 62.2% (n=3,154) and 64.1% (n=2,969) respectively. There are significant difference observed in comparison of HBsAg and anti-HBs seropositivity according to sex (p<0.05). From 1982 to 1986 on birth year, anti-HBs sero-positivity has been increased significantly from 63.3% to 73.3%. But the change of HBsAg sero-positivity has not been changed significantly. Conclusions : As compared with previous studies of HBsAg and anti-HBs, the sero-positive rate of HBsAg has not been changed but that of HBsAb has been increased significantly. This result revealed that the effect of HBV vaccination program was successful.

This study is to identify the effect of using admixture and polypropylene fiber on the quality of concrete. The results of the changes in the quality of concrete that has not yet hardened and concrete that has hardened is as follows: 1. Depending on the proportions of admixture, the greater the fly ash content and the lower slag and silica fume, the greater the slump. Admixture and polypropylene together contributed to increased slump. 2. The more fly ash, slag and silica fume added, the less the air. 3. After 360 days of age, greater fly ash content contributed to a lower compressive strength, while greater slag added to higher compressive strength. Silica fume shows a high compressive strength when 10% of silica fume was added on the 360th day of age. 4. Tensile Strength at 360 days of age, the less fly ash and the more slag, the higher the tensile strength. Silica fume at 360 days of age increase strength when the mixing proportion was 30%. 5. The more fly ash and the less slag and silica fume that were mixed, the greater the fire resistance. When added to and polypropylene fiber, the fire resistance of concrete of no effect. 6. The more fly ash and silica fume, the more carbonation shown and when there was only 10% slag present, the neutralization was also shown.

When reinforced concrete structures have a horizontal load, the strength capacity of the structure is not perfect. And when it is damaged by an earthquake load, it's weakness is more serious. Consequently if the structure is to be reused it reqires repair or restrengthening. This study investigates the structural capacity obtained in the repair-restrengthening of beams under static loads and beam-column joints under dynamic loads in reinforced concrete structures made with the repair-restrengthening method. Accordingly, a total of 18 tests were conducted and results obtained in tests which included test joints of beam-column. The results obtained were then compared and analyzed for hysteretic behavior, maximum stiffness, destruction, shearing transformation, energy dispersion capacity, structural capacity and problems of repair-restrengthening. The conclusions were as follows: The experimental variable which showed the most excellent reinforcement properties was the test in which carbon fiber laminate was attached with Super Found and it demonstrated the highest strength value. While cracks in the test objects under static loads were distributed widely across more concentrated at the joints of the beam-columns. Accordingly the development of repair-restrengthening materials and adhesives that do not show brittle fractures and that have ductile behavior characteristics should be promoted when dynamic load characteristics as occur in earthquakes are a factor to be considered.

Crohn`s disease is characterized by chronic transmural inflammation of the bowel and is associated with serious complications, such as bowel strictures, abscesses, fistula formation, and perforation. As neither medical nor surgical therapy provides a cure for Crohn`s disease, the primary goals of therapy are to induce and maintain remission and prevent complications. As a biologic agent, infliximab, a monoclonal antibody to tumor necrosis factor, is indicated for refractory luminal and fistulizing Crohn`s disease that does not respond to other medical therapies or surgery. Infliximab has proven to be very effective for inducing and maintaining remission in Crohn`s disease; however, infliximab treatment has several potential complications. Here, we report a case of free perforation following a therapeutic response after an initial dose of infliximab for Crohn`s disease. This is the first case report describing a free perforation in a Crohn`s disease patient after an initial dose of infliximab. (Korean J Gastroenterol 2013;62:169-173

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

The characteristics of stroke slightly vary as time changes. To compare the characteristics of stroke between the 1980s and 1990s we investigated the clinical records of stroke patients in 1987 and 1994. The subjects of this study consisted of the 1971 patients who were admitted as stroke patients to the Kyunghee University Oriental Medicine Hospital during these two years. There were 1092 stroke patients admitted from May, 1987 to April, 1988 and 879 stroke patients admitted between May, 1994 and April, 1995. The results were as follows. The frequency of cerebral infarction was 77.9% in 1987 and 79.9% in 1994. The male to female ratio of stroke patients was 1.4:1 in 1987 and 1.6:1 in 1994. The occurrence rate of stroke in both 1987 and 1994 were highest in patients in their 60s, followed by those in their 50s, 70s and older, in their 40s, and finally their 30s and below. We especially found that the rate of patients in their 70s and over increased from 17.8% in 1987 to 25.3% in 1994, which was remarkable in cerebral infarction patients. The most common disease preceding a stroke was hypertension, followed by heart disease and diabetes in 1987, and in 1994 hypertension was the most common, followed by diabetes and heart disease. The rate of recurrence among cerebral hemorrhage, that was 12% in 1987 and 24.7% in 1994. The most frequent complications of stroke in 1987 and 1994 were pneumonia and urinary tract infection, respectively. The prescriptions used most frequently during admission were Chungpaesagan-tang followed by Sunghyangjungki-san, Yangyeksanhwa-tang etc. in both 1987 and 1994. When patients were getting better, prescriptions for invigorating Qi and enriching the blood(補氣血) were used more frequently. In conclusion, the most remarkable change of stroke patients from 1987 to 1994 was an increase in occupancy rate of aged patients, especially those in their 70s and older. So we suggest that more research are needed on the stroke of aged man, along with many other subjects on stroke.

There is a need to improve the efficiency of the existing sanitary treatment facilities, because the effluent standard becomes more stricter and septic sludge increased. Thus, operating processes of sanitary treatment system in M city changed with installation of additional facilities. Process modifications were as follows: Dilution water was added to the next process after primary aeration tank. Some secondary sedimentation sludge was recycled to primary aerator so that most of the organics were stabilized in primary aeration tank under automatic control of dissolved oxygen. The line of effluent from dewatering process flowing to the activated sludge tank was changed to the primary aerator. The primary sedimentation sludge line was linked to a thickener. Polymer was added to the activated sludge tank. The effluent of primary aerator and aerobic digester was recycled from the 5th to the 1st sector. As consequencies of above process modifications, the improvement of removal efficiency was achieved as BOD 54%, COD 42%, SS 61%, T-N 39%, and T-P 12%, respectively.
