연구목적 : 산후 우울증은 10~15%의 산모가 경험하는 흔한 질환이다. 본 예비적 연구의 목적은 산후 우울증과 산전 위험요인으로 가족 적응력 및 응집성과의 관계를 알아보기 위함이다. 방법 : 24명의 산모를 대상으로 출산 전후의 시기에 전향적으로 연구하였다. 임신 36~40주에 산전 위험요인에 대한 질문지, Edinburgh 산후 우울증 척도(EPDS), 가족 적응력-응집성 평가 척도(FACES), Beck 불안 척도(BAI) 등을 시행하였다. 출산 후 4~6주에 구조적 면담으로 미니 국제신경정신인터뷰를 시행하여 산후 우울증을 진단하였으며 산후 위험요인에 대한 질문지, EPDS, BAI 등을 시행하였다. 결과 : 산후 우울증 군과 비 산후 우울증 군을 비교한 결과, 여러 v위험 요인 중 가족 적응력 및 응집성, 산전 우울증상 및 임신 중 기분 변화가 유의한 차이를 보였다. 로지스틱 회귀분석 상 임신 중 기분변화, 낮은 가족 적응력-응집성 평가 척도 총점 및 각 하위 척도 점수가 산후 우울증의 유의한 연관 요인으로 나타났다. 결론 : 본 연구의 결과는 산후 우울증에 있어 낮은 가족 적응력 및 응집성이 유의한 연관성을 가진 요인일 수 있음을 시사한다. 그러나 본 연구는 예비적 연구로 연구 대상 수가 적어 상기 결과가 지지되기 위해서는 대규모 연구가 필요하다. Objectives : Prevalence of postpartum depressive disorders reaches approximately 10-15% of childbearing women. This preliminary study was intended to explore the relationships between postpartum depressive disorders and family adaptability and cohesion. Methods : Childbearing women(n=24) were assessed for risk factors for postpartum depression before and after childbirth prospectively. At gestational age between 36th and 40th week, the questionnaire about various factors before childbirth, Edinburgh postnatal depression scale(EPDS), Family adaptability-cohesion evaluation scale (FACES), and Beck anxiety inventory(BAI) were assessed. After childbirth, for the diagnosis of postpartum depressive disorders, a structured diagnostic interview according to MINI International Neuropsychiatric Interview was performed, furthermore, the questionnaire about various factors after childbirth, EPDS, and BAI were assessed at 4-6 weeks postpartum. Results : Among various factors and scales, family adaptability and cohesion, mood symptom and change during pregnancy were associated with postpartum depressive disorder in comparison with non-postpartum depressive disorder subjects. In addition, low family adaptability and cohesion and mood change during pregnancy were significantly associated factors with postpartum depressive disorder using logistic regression analysis. Conclusion : The results suggest the postpartum depressive disorder could be related with prenatal low family adaptability and cohesion. This preliminary study, however, includes only a few subjects, so that further large-sized study will be needed to replicate our results.

Objective : This study was to investigate the effects of several herbs on the levels of MT1 and MT2 melatonin receptorsMethods : For this study, we carried out dementia assessment examination of 34 patients with memory disturbance who have come to Cheongju oriental hospital of Daejeon university from April 2005 to February 2006. This study classified the patients as none-dementia(ND), questionable dementia(QD), and dementia(DA) groups and analyzed the result of examination. Results : 1. The water extracts of Dimocarpus long (WEDL) induced the levels of MT2 melatonin receptor expression in a concentration-dependent manner without altering the levels of MT1 melatonin receptor expression. 2. The treatment with the water extract of Zizyphus vulgaris (WEZV) induced the levels of MT1 melatonin receptor expression and the levels of MT2 melatonin receptor expression was not affected. 3. The levels of MT1 as well as MT2 melatonin receptor expression were markedly up-regulated in the water extract of Fossilia ossis (WEFO) and the water extract of Ostreae caro (WEOC)-treated C6 cells. 4. The combination treatment with WEDL and WEZV induced not only the levels of MT1 melatonin receptor expression but also MT2 melatonin receptor expression, but the synergic effects of the combination treatment with WEFO and WEOC were not detected in C6 cells. Conclusion : The study provides important new insights into the possible mechanisms on the regulation of melatonin receptor synthesis by WEDL, WEZV, WEFO and WEOC.

Dynamic range on the digital detector can be a representation to the ratio of maximum and minimum of pixel value. Wide dynamic range and post processing ability of the digital detector made difficult to recognize visually to high or low dose images. We were evaluated a change of mean pixel value on the original and processed image, when we controlled the kVp, mA, exposure time on the digital detector. On the kVp of a constant condition, we were acquired an original and processed image by changes of mA, exposure time. According to the thickness of the subject under the same conditions, to determine a relation of pixel value and X-ray intensity, we used an aluminum step wedge. When mA and exposure times were changed under the kVp of a constant condition, the X-ray intensity was decreased by the reduction of the mean pixel value. In addition when kVp was increased in a constant condition of mAs, the mean pixel value was increased according to the increment of the X-ray intensity. Therefore, low kVp, high mA and short exposure time were a way to reduce a patient dose.

가스터빈 연소기의 화염 특성을 알기 위하여 분할 연소기 시험을 수행하였다. 점화시험은 여러 가지 연소기 유입 공기속도와 공기과잉율에 따라 토치 점화장치를 이용하여 수행되었다. 또한, 연료를 충분히 공급한 상태에서 점화를 수행한 후 점차 연료량을 감소시켜가며 희박연소한계를 측정하였다. 실험 결과, 공기과잉율 6에서 안정한 점화를 보였고 이 값은 연소기 공기 유입속도에 따라 점점 증가함을 보였다. 최소 실화한계는 연소기 공기 유입속도 40 m/s에서 약 4였고, 이 값은 연소기 공기유입속도에 따라 약 10까지 증가함을 보였다. 화염특성 시험결과, 화염안정성은 연소기 유입속도가 커질수록 희박화염소실한계는 넓어짐을 알 수 있었고, 연소기 유입 공기속도가 약 65 m/s에서 가장 큰 화염소실한계를 보였다. In order to see the flame behavior in the annular reverse gas turbine combustor, sector combustion test was performed. Ignition test by using torch ignition system was carried out at the various combustor inlet velocity and air fuel ratio. Also, flame blow out limit was measured by changing fuel flow rate with constant air mass flow rate. In the test results, stable ignition is possible at air excess ratio of 6 and this limit is gradually increased with combustor inlet velocity. The minimum blow out limit is about 4 at 40m/s of combustor inlet velocity. This blow out limit is also increased up to about 10 with increasing combustor inlet velocity. Test result shows that lean blow out limits are increased with air velocity. The highest blow out limit was found at the combustor inlet velocity of 65m/s.

This study was conducted to observe the bone and cartilage formation of mouse fetuses. Mouse litters were sacrificed at pregnant 14th and 18th day and examined for gross skeletal formation using cartilage and bone staining. We identified well developed cartilage formation at the 14th pregnant day in mouse fetus. However mouse fetus at the 14th pregnant day did not show any part of bone formation. At 18th pregnant day, mouse fetus showed well developed body shape and bone and cartilage formation. This results will provide basic information for the evaluation of mouse malfromation and impairment of skeleton formation. Further study will be needed for exact explanation of bone formation from cartilage portion.

In order to see the flame behavior in the gas turbine combustor, combustion test was performed by using sector combustor. Ignition test with torch ignition system was carried out at the various combustor inlet velocity and air fuel ratio. Also, flame blow out limit was measured by changing fuel flow rate with fixed air mass flow rate. In the test results, stable ignition is possible at air excess ratio of 6 and this limit is gradually increased with combustor inlet air velocity. The minimum blow out limit is about 4 at 40 m/s of combustor inlet velocity. This blow out limit is also increased up to about 10 with increasing combustor inlet velocity.

Having taken actions for 2 years, Net Neutrality User Forum has realized Net Neutrality as a international issue of future Internet. Although the Internet design principle (layering, module, IP protocol) has enabled the end users to communicate each other without any additional permission or interference, in the reality, the end users have been tracked by both companies and governments, and the communications could be blocked, or restricted by surveillance devices, such as DPI , which could change the whole Internet design principle. Given that the Internet is a large community of the equal end-users based on end-to-end principle, it`s essentially the issues of the whole Internet users, rather than of one nation, and we should focus on developing the transparent and participatory ways in Internet governance. The current Internet governance discussion have taken placed in ICANN, IGF, etc., in bottom-up processes of multistakeholderism to reflect the views of end-users. However there have been the controversial issues in Internet Governance, such as the position of government as a stakeholder, global north-south problem, transparency, so we have faced the debate on the new or evolving frame of Internet governance.

A pitch coating method was proposed for the purpose of improving the electrochemical properties of natural graphite. The synthesis conditions of pitch coating were optimized via measuring electrochemical properties of pitch-coated graphite anodes. As the synthesis temperature increased, the thermal stability was improved in addition to an increase in the softening point and residual carbon weight. However, the synthesis temperature of 430 ℃ resulted in the synthesis of a large amount of NI (NMP Insoluble) due to excessive condensation reaction. As the surface uniformity and coating thickness increased due to high thermal stability, the initial coulombic efficiency and rate capability of the pitch-coated graphite were improved. However, the graphite coated with the pitch containing excessive NI showed lower electrochemical properties than the uncoated graphite. NI had low dispersibility and formed spheres after heat treatment, so it formed the heterogeneous and thicker SEI layer. The optimum conditions for forming a uniform surface and an appropriate coating layer were investigated.
