Purpose: Herpes zoster appears in all ages and its incidence progressively increase. It is more common in elderly people or immunocompromised people and can be accompanied by serious complications. This study was performed to investigate the clinical manifestation of herpes zoster according to immune status in children. Methods: This study was retrospectively included 307 children under 18 years who were diagnosed and treated with herpes zoster at Inha University Hospital from 1997 to 2017 based on medical records. These patients were divided into two groups according to their immunity and their clinical features were compared. Results: The mean age of the total 307 patients was 10.2 years, 151 (49.2%) in males. Eighty-seven patients were hospitalized and 220 patients were treated in an outpatient clinic. Most patients received antiviral treatment. The most common dermatomal distribution of the skin lesion was the thoracic region, followed by trigeminal, lumbar and sacral, cervical region. Twenty-one patients were immunocompromised and fifteen of them were hematologic disorders. Admission rate, history of chickenpox and mean duration of treatment were significantly higher in immunocompromised group (P<0.05). There was no significant difference in age, dermatomal distribution and complication between the two groups. Complications were observed in 50 cases and more than half of them were zoster ophthalmicus. Another complication was Ramsay-Hunt syndrome, meningitis and skin infection. Conclusion: Immunocompromised patients had a longer duration of treatment and a higher history of chickenpox. The incidence of complications, dermatomal distribution and age did not differ from that of immunocompetent children.

In these days, the pollution of marine environment near island at Korean coastal zone caused by the trash human waste and livestocks excreata become intensified.<br/> One of the most economic and efficient way to prevent this pollution problem is to set up island circulating incineration system.<br/> In this paper, the result of feasibility study on the application of turtle boat hull form to the incinerating vessel has been summarized especially for the resistance and course keeping point of view.

수두 예방접종이 시행된 이 후 수두대상포진 바이러스의 합병증은 감소하고 있다. 하지만 면역저하환자의 합병증은 더욱 심한 양상으로 발현되기도 한다. 저자들은 13세 정상 면역 환아에서 수두대상포진바이러스에 의한 뇌수막염 증례를 보고하고자 한다. 환아는 3일전부터 발생한 두통, 발열을 주소로 입원하였고, 뇌척수액 검사에서 바이러스성 뇌수막염이 의심되었다. 입원 이틀째, 왼쪽 가슴(T7-8)에 발생한 피부 병변 및 뇌척수액 중합효소 연쇄반응을 통해 대상포진 바이러스에 의한 뇌수막염을 확진 하였고 정맥 내 acyclovir 투약 후 신경학적 증상 및 피부병변은 호전되었다. 환아의 혈청 면역글로불린 수치는 정상범위였고 기저 질환은 가지고 있지 않았다. 정상 면역 환아에서 수두대상포진바이러스의 재활성화는 피부 증상 이외에도 신경학적 합병증을 동반할 수 있기에 철저한 병력 청취, 신체 진찰 및 검사를 통해 빠른 진단 및 치료가 필요함을 본 증례를 통해 알 수 있었다. Neurologic complications associated with varicella zoster virus (VZV) are rare in children. A 13-year-old boy was hospitalized due to headache, fever, and vomiting. Aseptic viral meningitis was strongly suspicious based on findings on physical exam, cerebrospinal fluid examination, and brain magnetic resonance imaging. On the second day of hospitalization, typical zosteriform rashes developed on his left chest wall across the T7-T8 dermatome. Tzanck test of the skin lesion was positive and polymerase chain reaction test for VZV was positive on the second cerebrospinal fluid examination. Serum immunoglobulin levels were within normal range. Intravenous acyclovir was started and symptoms and signs of meningitis gradually improved and the patient was discharged without any complications. In immunocompetent children, VZV meningitis is rare and requires rapid diagnosis and treatment. Therefore, it is necessary to prompt diagnosis and treatment thorough medical history, physical examination and laboratory examination.

Epitaxial ZnO nanowires (NWs) were synthesized on sapphire (001) substrates using a hydrothermal process. The effects of the pH value of the precursor solution on the structural and optical properties of the resulting NWs was studied. The epitaxial relationship and the domain matching configuration between the sapphire (001) substrate and the as-grown ZnO NWs were determined using synchrotron X-ray diffraction measurements. The (002) plane of $w{\ddot{u}}rtzite$ ZnO NW grows in the surface normal direction parallel to the sapphire (001) direction. However, three types of in-plane domain matching configurations were observed, such as the on-position, $30^{\circ}$-rotated position, and ${\pm}8.5^{\circ}$-rotated position relative to the on-position, which might be attributed to inheriting the in-plane domain configuration of the ZnO seed layer.
