Objectives: This study aimed to evaluate the association between internet addiction and Attention-Deficity/Hyperactivity Disorder (ADHD) among senior students in some elementary schools. Methods: Total 1,172 students of 4 elementary schools were chosen. General characteristics,health-related behavior, internet addition(K-scale), and ADHD were collected using self-reported questionnaires. Chi-square tests, t-tests and multiple logistic regression analysis were performed to assess the association between internet addiction and ADHD symptoms. Results: Amongst 1,172 subjects, boy students were 628 (53.6%) and girl students were 544(46.4%). The prevalence of ADHD was 65 (5.5%). With regard to internet addiction, 157 (13.4%),106 (9.0%) and 909 (77.6%) of the students were categorized as high-risk group, potential-risk group and normal group, respectively. The odds ratio for ADHD was significantly higher in potentialrisk group (OR=20.08, 95% CI=3.51-114.92) and high-risk group (OR=125.77, 95% CI=24.46-646.66) than normal group. Also, internet addiction score was significantly associated with ADHD symptoms OR=108, 95%CI=1.06-1.11). Conclusions: Internet addiction was associated with ADHD in late elementary students. Further study is need to investigate the biologic mechanism between internet addiction and ADHD.

Langerhans cell histiocytosis (LCH) is a rare disease having an unknown etiology, but characterized by a disorder of antigen presenting cells and the mononuclear phagocytic system. Neonatal LCH, defined as LCH presenting within the first 4 weeks of life, accounts for less than 5-6% of the total LCH cases. Skin involvement of neonatal LCH tends to regress spontaneously, as has been shown in Hashimoto-Pritzker syndrome. We report a case of LCH that presented as whole body, polymorphic, generalized, erythematous, yellowish plaques at birth, with no evidence of other organ involvement. These skin lesions regressed spontaneously within 14 days. Two weeks later, however, the patient presented with hepatosplenomegaly, fever, hyperbilirubinemia, anemia and leukocytosis. LCH with liver involvement was shown on abdominal MRI findings, and the patient received systemic chemotherapy. Although neonatal LCH may initially only show skin manifestations, it should be followed up closely and periodically for other organ involvement.

The paper tried to search the characteristics and performances of the new business openers in the area of the beauty salon business. Most of the business owners are women and university graduates. They are mostly active and positive. The search found that the location is one of the most important subject in the small service business. They also tend to calculate the revenues and expenses everyday. They pay lots of attention for the financial performance. They were not much confident with their capital raising. The lowest point was in the area of governmental support. The size and equity capital followed next. The regression analysis showed that continuous marketing activity is important for the performance of the venture.
