This article describes and illustrates cases the treatment of primary and secondary encopresis using a changing conditions and criterion design with two subjects. The dependent variables measured were increase in appropriate toileting behavior and decrease in inappropriate toileting behavior. After 12 and 13 weeks of treatment encopresis was completely eliminated. In a two-month follow-up and one year follow-up inappropriate toileting behavior was not reported. Appropriate toileting behavior was also reported generalized to settings outside the home.

Purpose: The purpose of this study was to evaluate the long term outcome and the factors contributing to treatment outcome for chronic functional constipation in children. Methods: Sixty three children were enrolled who had chronic functional constipation and could be followed by telephone contact. They were treated at the Bucheon Soonchunhyang Hospital for more than 1 month and observed from March 2001 to June 2005. We analyzed the clinical features, symptoms and signs, as well as the course and results of treatment. Results: The male to female ratio was 35 (55.6%) : 28 (44.4%). The mean age at the onset of symptoms and diagnosis was $21.1{\pm}23.5$ (1.9~84.0) months and $47.1{\pm}34.2$ (6.9~138.0) months, respectively. The mean defecation frequency before treatment was $3.2{\pm}2.3$ (0.5~10.0) times per week. The symptoms associated with constipation were as follows: soiling 34 (54.0%) which was more common in males than females, large stools in 30 (47.6%), decreased bowel movements less than three times a week in 20 (31.7%), straining during defecation in 19 (30.2%) and retentive posturing 19 (30.2%). The mean duration of follow-up was $34.2{\pm}14.6$ (3.6~60.0) months and 44 (69.8%) patients had their symptoms resolve ("success") and 19 (30.2%) were not resloved ("fail") from the constipation. The time for recovery from soiling, straining during defecation and retentive posturing after treatment was $4.3{\pm}2.4$ (1.0~36.0), $5.0{\pm}1.4$ (0.8~36.0) and $5.0{\pm}3.1$ (1.0~36.0) months, respectively. A relapse of the constipation occurred in 15 (23.8%) patients, 9 (60%) boys and 6 (40%) girls. The time to relapse after cessation of treatment was $2.9{\pm}1.9$ (1.0~6.0) months and the only risk factor associated with relapse was the initial duration of treatment. Conclusion: Most of the patients had resolution of symptoms within five months after treatment; relapse occurred within three months after the interruption of treatment. The duration of treatment was important for recovery and for the prevention of relapse in the constipated children. Thus a long term maintenance of therapy and follow-up is necessary for chronic functional constipation in children.

Purpose: Anorectal manometry is a way of investigation for ano-rectal sphincters. In this paper we evaluated the usefulness of anorectal manometry in constipation patients and compared the anal spnincter function in control, constipation and encopresis patients Methods: We analysed the data of anorectal function studies in normal children (control, n=11), children with constipation (constipation group, n=20) and children with encopresis (encopresis group, n=16). Results: The specific manometric parameters in normal children were like as follows; external anal sphinter pressure $21.0{\pm}8.00$ mmHg, internal anal sphicter pressure $30.0{\pm}14.57$ mmHg, conscious rectal sensitivity threshold $11.4{\pm}4.52$ mmHg. The above results were not different from that of previous studies except conscious rectal sensitivity threshold, which was slightly lower than that of others. Internal and external anal sphincter pressure were elevated significanlty in constipation and encopresis groups than in control, which results was the same in conscious rectal sensitivity threshold. But the values of rectoanal inhibitory threshold and percent relaxation of rectoanal inhibitory reflex were not different among control group, constipation group and encopresis group. External sphincter activity was increased during the act of bearing down for defecation in none of the child in control group, in 6 of 17 children in constipation group and 5 of 12 children in encopresis group. Conclusion: With the results of above we could say that complete history taking and physical examination are important in diagnosis of constipation, and we could say also that the anorectal manometry was a valuable tool to understand the physiology of normal defecation and the pathophysiology of constipation and encopresis.

Purpose : The aim of this study was to compare 2 laxatives, namely, polyethylene glycol 4000 without electrolytes and lactulose, evaluating the efficacy and safety for the treatment of constipation in children. Methods : Fifty-six children with chronic functional constipation were randomly assigned to receive polyethylene glycol 4000 (24 patients) or lactulose (32 patients). Patients or their parents reported defecation frequency, stool consistency, abdominal pain, stool incontinence and side effects after 1, 3, 6 and 12 months of treatment. Percentage of recovered patients were compared with each group. Results : Defecation frequency, abdominal pain and stool incontinence were improved in each group. At 12 months of follow up, 60% of patients treated with polyethylene glycol and 57.7% of patients treated with lactulose were considered as recovered. Conclusion : In this study, both polyethylene glycol and lactulose were equally effective and safe in the long-term treatment of constipation in children. There were no significant differences in recovery rates between 2 groups.

By studying bioactivity in the aspect of skin care via curcumin, the main component of turmeric, and isoflavones, the soybean extract, this research tried to prove the possibilities as cosmetic ingredients. This research identified the curcumin and soybean extract's anti-inflammatory and toxic effects on skin cells through cell experiment, and using HPLC, the moisture, oiliness, and changes in erythema were measured when the soybean extract was applied to the skin. The result showed that curcumin had the least toxin on RAW 264.7 cell and the anti-inflammatory effect was identified. There were statistically significant changes on the moisture, oiliness and erythema when cosmetics containing curcumin and soybean extract were used. Therefore, it showed the possibilities of the utilization of curcumin and soybean extract to be used as cosmetics for acne skin.

Purpose : We aimed to determine the ideal age for initiating toilet training and investigate the factors influencing the training. Methods : The study population comprised 1,370 children aged 2-6 years, who visited the pediatric clinics in Jeonju, Iksan, and Gunsan. Their parents were given questionnaires in order to gather data about the types of diapers used, ages when toilet training was initiated and completed for each day and night, its adverse effects, and the educational level and employment and economic status of the mothers. Results : The toilet training initiation age was low for those living in the country, having an elder sibling(s), and using cloth diapers, and for those whose mothers were employed and had a low economic status. The training completion age was 22.9 months when the training was initiated before the age of 18 months; this was lower than the training completion ages of 25.9 and 31.0 months when the training was initiated at the age of 18-24 months and after 25 months, respectively. However, the required durations in these cases were 8.4, 5.6, and 3.8 months, respectively. Encopresis and refusal occurred more often when the training was initiated before the age of 18 months than when initiated after this age. Conclusion : Toilet training should begin at least after the age of 18 months considering the developmental status of infants. It is recommended for the future researchers to develop specific guidelines regarding toilet training.

Enuresis is repeated involuntary or intentional voiding of urine into bed or clothes over age 5. Though it would be a self-remitting disorder, it could be serious problem in emotional and socio-adaptational aspects. The author reviewed the enuretic patients of Child & Adolescence psychiatric section in Chungnam National University Hospital during past 3 years. 46(4.9%) of 936 patients were diagnosed as enuresis in DSM-Ⅳ. The author evaluated their comorbidity by the data of diagnostic review made in two psychiatrists, and emotional aspects(self-concept, anxiety, depression) through the self-rating scales (Piers-Harris children’ self concept scales, RCMAS, state-trait anxiety inventory for children, child’s depresson inventory). Thirty(65.2%) of the 46 enuretic patients had additional diagnoses such as attention deficit hyperactive disorder, mental retardation, encopresis, oppositional defiant disorder, depression, anxiety disorder, autism, somatoform disorder, tic disorder, obsessive-compulsive disorder, sleep disorder, etc. Sixteen enuretic patients had at least one comorbid disorder. Eleven patients had two, and three patients had more than three. Fourteen of 46 enuretic patients were evaluated through self-rating scales of self-concept, anxiety and depression. But we couldn’t obtain meaningful results. Maybe it was due to the small sample size(N＝14) and the influence of the comorbid disorders. Finally, it was an impressive evidence that there exist many comorbid disorders in enuresis(esp. attention deifict/hyperactive disorder). In emotional aspects, the author thought that further evaluation should be needed for more meaningful results.

The rheological properties of dough made with 0% 1 % 2% or 3% Corni fructus flour were investigated Rapid Visco Analyzer (RVA) analysis showed that the initial pasting temperature increased with increasing Corni fructusflour content, while the peak viscosity decreased. The water absorption, stability, development time, elasticity and valorimeter value of the dough, as determined using a farinograph and alveograph, decreased with increasing amounts of Corni fructusflour, while weakness increased. The extensibility, fermented volume and consistency of the dough increased gradually with increasing Corni fructus flour content. These results indicate that the addition of Corni fructus flour affects the rheological properties of bread.

Selective mutism is a childhood condition defined by persisten failure to speak in specific social situation when speaking is expected, dispite preserved ability to comprehend spoken language and speak. Present study is to investigate clinical characteristics, treatment method and outcome of 23 children who were diagnosed as selective mutism by DSM-IV criteria at the child psychiatry ouptatient department of SNUH. The results were as follows : 1) The Sex ratio was 1: 4.8, female dominant Mear age of onset was 33 years old and mean age of first referral was 7.7 years old. 2) 22% of subjects had perinatal problem such as low birth weight, preterm birth, 26% of the subjects have history of delayed language development. There are subjects who had been separated with mam caretaker before 3 years old(26%) and who experienced physical or psychological trauma before 3 years old(26%). A few subjects had enurests(30%) and encoprests(4%). 3) Many subjects(65%) had symbiotic relationship with their mother. These families consist of dominant, verbally aggressive mother and passive father. Parents of 39% of all subjects were judged to have definite psychopathology(social phobic, depression, hysterical trait or alcohol problem) 26% of all subject, were reported physically abused. 4) The personality trait of the subjects were frequently described as follows(in order of frequency) ; Shy(100%), anxious(83%), stubborn(83%)m rigid and tense posture(78%), immature(65%) overdependent(65%), irritable(52%), manipulative(39%), depressive(39%). 5) The mean performance IQ of 16 subjects by KEDI-WISC was 88.3 Among them, the subjects with IQ below 69 were seven and those with IQ above 70 were nine. When comparing these two group(Mental retardation group vs Normal IQ group), we could find some difference in language development, personality trait, family dynamics and treatment outcome. 6) Among several treatment methods for selective mutism, play therapy was the most frequently used method(65%). Other commonly used treatment methods were pharmacotherapy(21%), behavioral therapy(8%), combined therapy(play therapy+pharmacotherapy+family therapy+behavioral therapy)(12%), 7) Regarding the outcome of treatment 8.6% was evaluated as Excellent, 30.4% as Good, 52% as Fair, 8.7% as Poor at the tinic of treatment. At follow up interview 21.7% was evaluated Excellent, 13% as Good, 21.7% as Fair, 34.8% as Poor. 8) We classified all subjects by Havden's 4 subtype. Symbiotic mutism was most common(65%) and other subtypes are Speech phobic mutism(8.6), Reactive mutism(13%) and Passive-aggressive mutism(30%).
