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. 본연구는G광역시소재4개초등학교에재학중인5, 6학년학생을연구대상으로인터넷중독과ADHD 와의관련성을 파악하였다. 자료수집기간은 2012년7 월 9일에서 7월 20일까지였다. 본 연구의 대상은 총1,172명을 최종 분석 대상자로하였고 남자는 628명(53.6%), 여자는 544명(46.4%)이었다. 인터넷 중독은한국형 인터넷 자가진단검사인K-척도를사용하였고, 주의력결핍과잉행동장애(ADHD)는 DSM- IV 의 기준으로 재구성한 설문지를 사용하였다. 연구결과 ADHD는 총 1,172명중 정상군은 1,107 명(94.5%), ADHD군 65명으로 유병률은 전체 5.5 %이었으며, 남자9.2%, 여자1.3%로 남자가여자보다많았다. 인터넷중독은고위험사용군157명(13.4%), 잠재적위험사용군106명(9.0%), 일반사용군909 명(77.6%) 이었다. 다중로지스틱회귀분석 결과일반사용 군을 기준으로 했을 때 잠재적 위험사용군인 경우비차비 20.08 (95% CI 3.51~114.92), 고위험 사용군인 경우 비차비 125.77 (95% CI 24.46~646.66) 로 ADHD일 가능성이 유의하게 높았다. Model II은인터넷 중독 점수를 로지스틱 회귀분석을 하였을 때비차비 1.08 (95% 신뢰구간 1.06~.11)로 중독점수가높을수록ADHD일가능성이높았다. 따라서초등학교고학년아동의인터넷중독과ADHD와는관련성이있었고, 향후변수 간의인과관계를좀 더명확히밝힐수 있는 연구가 필요할 것으로 사료된다.

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.

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.

Purpose: Congenital hypothyroidism (CH) is the most common cause of preventable mental retardation. Recently, the detection of CH cases with eutopic thyroid gland has increased due to neonatal screening programs. In this study, we aimed to identify and evaluate predictive factors that could distinguish between permanent and transient CH in patients with eutopic thyroid gland. Methods: We retrospectively reviewed 100 children diagnosed with CH and with eutopic thyroid gland. All subjects were treated with levothyroxine and underwent re-evaluation after 3 years of age. Results: Of the 100 CH patients, 35 (35.0%) were diagnosed with permanent CH (PCH) and 65 (65.0%) were diagnosed with transient CH (TCH). The initial thyroid stimulating hormone levels were significantly lower in the TCH subjects than in PCH subjects. In addition, the mean doses of levothyroxine (μg/kg/day) at the 1st, 2nd, and 3rd year of treatment were significantly lower in subjects with TCH than in PCH subjects with eutopic thyroid gland. Based on the receiver operating characteristic (ROC) curve, the optimal cutoff dose of levothyroxine at 3 years of 2.76 μg/kg/day could predict TCH, and was associated with 87.3% sensitivity and 67.6% specificity, with an area under the ROC curve of 0.769. Conclusion: The levothyroxine dose requirement during treatment period has a predictive role in differentiating TCH from PCH in CH patients with eutopic thyroid gland.
