Background : Intravenous(Ⅳ) access is becoming an increasingly important part of health care today. The current drive for clinical effectiveness and cost-effective health care serves to increase the need for reliable vascular access. Venous access devices were developed to overcome problems associated with limited peripheral access and frequent venipuncture in patients with long-term therapy. Although the peripherally inserted central catheter(PICC) have become popular during recent years in USA, its procedure is rare in Korea. Purpose : The goal of this study was to analyze the PICC inserted patient data by Ⅳ CNS intervention. Method : A Total of 62 PICCs were inserted into 51 patients by the Ⅳ CNS during a 10-month period form November, 14, 2002, to October 2, 2W2. Data was obtained retrospectively through chart review. Result : The patient population included 34(54.8%) men and 28(45.2%) women, with a mean age 50.6 years. The main indication for PICC placement was to access vein in poor peripheral venous status(40.3%). The mean served interval for PICC insertions was 16.7 days(range, 2~61 days). The reasons for removal were completed therapy in 18 cases(29.0%), patient death in 13 cases(21.0%), and mechanical or functional PICC problem in 10cases(16.1%). The three PICCs removed for presumed infection, and one had only positive tip cultures(0.2%). Conclusion : PICCs are rapidly growing popularity and required an extended course of Ⅳ therapy.

Luminescence Properties of InAlAs/AlGaAs Quantum Dots Grown by Modified Molecular Beam Epitaxy

Se Ra Kwon,Mee-Yi Ryu,Jin Dong Song 한국진공학회(ASCT) 2014 Applied Science and Convergence Technology Vol.23 No.6

Self-assembled InAlAs/AlGaAs quantum dots (QDs) on GaAs substrates were grown by using modified molecular epitaxy beam in Stranski-Krastanov method. In order to study the structural and optical properties of InAlAs/AlGaAs QDs, atomic force microscopy (AFM) and photoluminescence (PL) measurements are conducted. The size and uniformity of QDs have been observed from the AFM images. The average widths and heights of QDs are increased as the deposition time increases. The PL spectra of QDs are composed of two peaks. The PL spectra of QDs were analyzed by the excitation laser power- and temperature-dependent PL, in which two PL peaks are attributed to two predominant sizes of QDs.

Objective : The following study uses data from the “2020 Analysis of Living Conditions of the Elderly” and aims to recognize difference in mood and cognition based on how elderly people participate in society. Methods : Based on the data from “2020 Analysis of Living Conditions of the Elderly”, provided by the Korean Institute for Health and Social Affairs, a secondary data analysis was performed on 10069 elderly citizens over the age of 65. In order to spot influences on depression, a Geriatric Depression Scale-K test had been conducted, and a Korean version of Mini-Mental State Examination was used to analyze what could potentially alter cognition. Results : According to the analysis on how social interactions affected the mood and cognition of elderly people, the results showed that those who didn’t participate in social groups had the highest levels of depression and cognition decline. Additionally, lower levels of depression and increased mental capacity was proportional to the amount of social participation. Conclusion : Social participation plays a big role in older people’s mood and cognition, thus it is essential to facilitate those needs. 연구목적 본 연구에서는 2020 노인실태조사 데이터를 이용하여 노인의 사회참여 유형에 따른 우울과 인지의 차이를 보고자 한다. 연구방법 한국 보건사회연구원에서 제시한 2020년도 노인 실태조사 데이터를 활용하여 10069명의 65세 이상 노인들을 대상으로 이차자료 분석(secondary data analysis)를 시행하였다. 우울에 미치는 영향을 알아보기 위해 노인 우울 간이 척도(Geriatric Depression Scale-K; GDS-K)를 시행하였고 인지에 미치는 영향을 알아보기 위해 (Korean version of Mini-Mental State Examination; MMSE-K)를 이용하여 분석하였다. 연구결과 노인의 사회참여 유형별로 우울과 인지기능의 현황을 확인한 결과 정신사회단체에 참가하지 않았을 때 우울이 가장 높고 인지기능이 가장 낮았다. 사회참여 항목별 사회참여 여부에 따른 우울 및 인지기능 차이에서 학습활동과 정치사회단체를 제외한 친목 단체, 동호회, 여행이 유의한 차이를 나타냈다. 결론 노인에게 사회참여의 유형에 따라 우울과 인지기능에 영향을 미치므로 그에 따른 중재가 필요하다.

목적: 양수 내 태변착색이 발생한 만삭 임신과 태변착색이 없는 임신 간에 분만 전 후의 주산기 예후를 비교하여 이를 바탕으로 태변착색을 동반한 임신의 분만 관리에 도움이 되고자 본 연구를 진행하였다. 방법: 1년 동안 있었던 687 건의 만삭 분만을 양수 내 태변착색이 있었던 89건과 태변착색이 없었던 598명의 두 군으로 분류하였으며 각 군의 분만 및 신생아의 특성을 비교하였다. 산모 연령과 임신주수, 신생아 체중 및 분만방법을 조사하였고 진통 중 안심할 수 없는 태아 심박동 상태의 발생여부, 1분 및 5분 아프가 점수를 살펴보았다. 제대 동맥혈 가스분석을 시행한 577건에서는 제대 동맥혈의 pH, 이산화탄소 분압, 염기결핍의 정도를 조사하였다. 결과: 양수내 태변착색이 있는 군은 태변착색이 없는 군에 비해 진통 중 안심할 수 없는 태아 심박동 상태의 발생이 더 많았고(4.5% vs. 1.0%, p=0.03) 제대 동맥혈 평균 pH값이 7.28±0.13으로 태변착색이 없는 임신에 비해 유의하게 낮았다(p=0.008). 중증의 태아 산증을 의미하는 제대 동맥혈 pH가 7.0 미만인 경우도 총 3.4% 발생하여 태변착색이 없는 경우에 비해 유의하게 많았다(p=0.01). 그러나 대사성 산증의 위험도는 높지 않았으며 분만 후 1분, 5분 아프가 점수도 두 군에서 유의한 차이가 없었다. 결론: 태변착색 임신의 발생율에 비해 분만 후 신생아 상태가 불량한 경우는 많지 않았다. 그러나 발생 가능한 태아 심박동 이상과 태아 산증에 대비해서 분만 중 지속적인 심박동 감시 및 분만 후 주의 깊은 신생아 평가가 필요하다. Purpose: The purpose of this study was to compare the obstetric and perinatal outcome between two groups with or without meconium staining of amniotic fluid (MSAF) at term birth in one-year consecutive population at our delivery unit. Methods: Pregnancy complication including nonreassuring fetal heart rate pattern, intrauterine growth retardation, oligohydramnios, hydramnios and preeclampsia between the two groups were retrospectively documented by review of medical record. To evaluate the perinatal outcome, apgar score at 1min and 5min, and umbilical artery blood gas analysis were also analyzed. Student T test and chi square test were used for statistic analysis. Results: The study population consisted of 687 full-term neonates with presence (n=89) and absence (n=598) of MSAF. Gestational age at delivery was significantly higher in the MSAF group (p<0.001). Although the fetal acidemia (umbilical artery blood pH <7.0) was significantly higher in the MSAF group (3.4% vs 1.0%, p<0.01), the metabolic acidemia (base deficit>12.0 mEq/L) was not increased. The incidence of non reassuring fetal heart rate pattern was also increased in the MSAF group (4.5% vs 1.0%, p=0.03). However there was no significant difference in 1 min and 5 min Apgar score. Conclusion: Although MSAF is associated with the risk of non reassuring fetal heart rate pattern and fetal acidemia, the metabolic acidemia and low apgar score at 5minutes was not significantly increased compared with clear amniotic fluid group. Delivery of pregnancy with MSAF should be managed under the careful fetal heart rate monitoring.

Ti nanopowder was prepared by high energy ball milling. The milled Ti and CNT powders were then simultaneously synthesized and consolidated using high frequency induction heated sintering (HFIHS) within one minute under applied pressure of 80 MPa. The milling did not induce any reaction between the constituent powders. Meanwhile, HFIHS of the Ti-CNT mixture produced a Ti-TiC composite according to the reaction (0.94Ti + 0.06CNT→ 0.88Ti + 0.06TiC, 0.88Ti + 0.12CNT→ 0.76Ti + 0.12TiC). Highly dense nanocrystalline Ti-TiC composites with a relative density of up to 99.5 % were obtained The hardness and the fracture toughness of the dense Ti-6.4 mole% TiC and Ti-13.6 mole% TiC produced by HFIHS were also investigated.
