Encephalocraniocutaneous lipomatosis(ECCL) is a rare, sporadically occurring a type of congenital neurocutaneous syndrome that characteristically involves ectomesodermal tissues, such as the skin, eyes, and central nervous system(CNS). Etiology is unknown, but the hypothesized genetic mechanism involves lethal autosomal dominant genes that survive by mosaicism, and the paghogenesis most likely involves dysgenesis of the cephalic neural crest and anterior neural tube. Clinically, Nevus psiloliparis(NP) and choriostoma are major criteria of ECCL and NP is a particularly characteristic criteria in skin anomalies.Intracranial lipoma, intraspinal lipoma, jaw tumor, bone cyst, aortic coarctation are other major criteria except for skin. In definite case, three systems have to be involved and two or more major criteria is required. In our case, a 9-year-old tajikistan children visited with left lower leg and foot hypertrophy for 3 years. Physical examination revealed patchy alopecia, nevus psiloliparus, unilateral whorled hypermelanosis, choriostoma, intracranial lipoma, hemihypertrophy. Additionaly, a biopsy of the hypertrophic leg revealed thickening of the subcutaneous fatty tissue with lobular proliferation. Therefore, the children was worth of diagnostic criteria. Herein, we report a educational and globally rare case of ECCL.

Sweet syndrome(acute febrile neutrophilic dermatosis) ischaracterized by abrupt onset of fever, leukocytosis, and tender erythematous nodules or plaques. Generally, sweet syndrome does not respond to antibiotic therapy, but steroids are very effective and promptly improve skin lesion. Also, sweet syndrome is associated with a variety of disorders, including hematological malignancies and solid tumors, autoimmune diseases, inflammatory bowel disease, infections, medications, and pregnancy. In this case, a 5-year-old female children visited us who had painful erythematous indurated plaques on Rt. periocular and Lt. zygomaic area after using granulocyte colony-stimulating factor(G-CSF) for aplastic anemia. She was diagnosed as sweet syndrome induced by recombinant G-CSF, which was improved after drug withdrawl and systemic corticosteroid treatment. Herein, we report a very rare case of sweet syndrome in a child with aplastic anemia after receiving recombinant G-CSF.

Patient with Gianotti-Crosti Syndrome (GCS) presents with a distinctive self-limiting acral papular or papulovesicular eruption. Patient with GCS is associated with an underlying viral and bacterial illness. GCS is a self-limiting cutaneuous response to different infections. Its clinical differences are probably due to individual characteristics of each patient rather than the causative infections agents. GCS in patients infected with hepatitis A virus has not been reported previously in Korea. We report a case of 16-year-old girl who developed an erythematous papular eruption on her extremities a week after an epidemic of hepatitis A. The patient had the characteristics which resembled clinical and histopathologic findings of GCS. Hepatitis A virus RNA was detected by nested reverse transcription-polymerase chain reaction of tissue from lesion site of the patient.

FRP reinforcement of the RC (reinforced concrete) members is being widely used be cause of its workability and good performance. However, in the case of the generally used surface bonded method, the degradation of the bonding performance, which is the most important part of FRP reinforcement, frequently happens. In order to solve this problem, the differences between the surface bonded method and the auger-drilled piling were compared and analyzed according to the bonding length for the same amount of FRP, and three subjects of the surface bonded reinforcement and three subjects of the bar-filling reinforcement, so six subjects in total, were produced and compared in this research. A bonding experiment was conducted to asses their bonding performance, and the variables were the type of filling and the length of bonding. To examine the reinforcing effects of each subject, the maximum weight, the early cracking weight, the maximum displacement and the displacement of the early cracking of each subject were measured and recorded, and according to them, the bonding length of FRP-plate and the reinforcing effect of each type of filling were analyzed. As the result, it was proved that the filled-in FRP-plate was better than the general surface bonded and reinforced FRP-plate in terms of the maximum weight and the displacement.

Electroluminescence is the light emission obtained by an electrical excitation energy passing through a phosphor under an applied high electrical field. The preparation and characterizations of light emitting ACPEL(alternating-current powder electroluminescent) cell based on ZnS:Cu powder are discussed. ACPEL device is useful for large flat panel display. Phosphor used in this work was prepared following conventional method with ZnS, CuBr₂ mixed powder at 1200℃. The structure is IT0/Insulating layer/Active layer/Insulating layer/Silver paste. Basic properties of insulating layer and binder used in this work was investigated to understand the effect of dielectrics.

연구목적 본 연구는 대사증후군의 예방과 회복을 위해 5년 동안 추적이 가능한 만성 조현병 환자에서 대사증후군의 변화와 예측인자를 조사하였다. 방 법 2011년부터 2016년까지 추적이 가능하며 동의서에 동의한 107명의 환자가 본 연구에 포함되었다. Revised National Cholesterol Education Program-Adult Treatment Panel III(NCEP-ATP III)를 이용하여 대사증후군을 정의하였다. 결 과 추적 관찰 기간 동안 22명(20.5%)의 환자가 새롭게 대사증후군에 진단되었고 14명(13.1%)는 대사증후군에서 회복되었다. 77명(66.4%)은 변화가 없었다(대사증후군이 있는 환자:34명[31.8%], 대사증후군이 없는 환자 : 37명[34.6%]). 복부둘레와 중성 지방이 대사증후군의 유무가 변화된 환자들에서 중요한 인자였다. 다른 변수를 통제한 다변량 회귀분석에서 여성(OR=2.846, 95% C.I. 1.020-7.942), 1달에 1회 이상 외래 방문(OR=3.155, 95% C.I. 1.188-8.379), 항우울제 병합치료(OR=3.991, 95% C.I. 1.048-15.205)가 대사증후군의 유병률에 유의한 영향을 주었다. 반면에 항정신병 약물의 종류나 용량은 대사증후군의 유병률에 영향을 주지 못했다. 결 론 만성 조현병 환자에서 약제의 변경 및 용량조절보다 증상에서의 회복과 건강한 생활 습관이 대사증후군에 중요하다. Objectives : To investigate changes in, and predictors of, metabolic syndrome(MetS) status over a 5-year period in chronic schizophrenic patients and to identify factors associated with the prevention of or recovery from MetS. Methods : In total, 107 patients, all of whom provided written informed consent, were followed from 2011 to 2016 at Naju National Hospital for this study. MetS was defined according to the revised National Cholesterol Education Program-Adult Treatment Panel III guidelines. Results : During follow-up period, 22(20.5%) patients were newly diagnosed to MetS, 14(13.1%) were disappeared, 77(66.4%) were not changed[MetS : 34(31.8%), No MetS 37(34.6%)]. Common significant factors in the two changed groups were triglyceride and waist circumference, not dose and type of antipsychotic medication. Multiple logistic regression analysis revealed that female gender(odds ratio[OR]=2.846, 95% confidence interval[CI] : 1.020-7.942), attending two or more outpatient visits per month(OR=3.155, 95% CI : 1.188-8.379) and taking antidepressant medication(OR=3.991, 95% CI : 1.048-15.205) were significantly associated with MetS after controlling for other confounding variables. Type and dose of antipsychotic medication were not significantly associated with MetS. Conclusions : Triglyceride and waist circumference were important manageable indicator of MetS. Adoption of a healthy lifestyle is more important than adjusting the dose or type of antipsychotic medication in the treatment of chronic schizophrenia patients with MetS.

무선 환경에서 노드의 위치가 랜덤하게 분포되어 있고 그 중에 일부를 네트워크 코딩(Network Coding)을 적용하였을 경우의 이득으로 최적의 NC Density(Network Coding Density)를 구한다. 최적의 NC Density에 해당하는 타겟 SIR를 결정하여 전송 전력을 정하여 전송률을 향상시키고자 한다. 본 논문에서, 네트워크 내의 통신 경로의 최적화 및 통신 혼잡이나 통신 지연을 최소화할 수 있는 에드-혹(Ad-Hoc) 환경을 구축할 수 있고, 에드-혹 네트워크의 전력 사용의 효율을 높일 수 있다.
