The purpose of the study was to analyze the factors of family savings with time series data. The data used was quarterly data of 1980 to 1991. Family savings were defined as disposable family income minus total consumption, which were taken from Annual report on the family income and expenditure survey by National Statistical Office. The results showed that family income was the most crucial factor of family savings. Both permanent and temporary family income were also positively related to the amount of family savings. Especially, the change rate by temporary income to family savings was found to be bigger than that of permanent income. Other factors considered in the estimated model were not found to be statistically significant factors on family savings, such as interest rate, consumer price index, and price change of real estate.

The purpose of this study is to examine the effect of wife's employment to the household expenditures by wife's occupation. The data used in the study was taken from 1996 National Survey of Family Income and Expenditure sponsored by National Statistical Office. Of total sample, 30.1% were employed-wife households. About 78% of wives in employed-wife households in the sample were employed in service or labor work. After controlling total household income and other household characteristics, total expenditures were lower for the employed-wife households compared to non-employed-wife households. When wife was working in professional or managerial occupations, the households spent more than non-employed-wife households in domestic services, child care, clothing, and private transportation. On the other hand, the households with wives working in service or labor works spent less in health care, furniture and household appliances, and tax while spent more in child care, and education than non-employed-wife households.

梁文浩,曺東鉉,安世永,鄭定烈,杜鎬京 慶熙大學校韓醫科大學韓醫學硏究所 1995 慶熙韓醫大論文集 Vol.18 No.2

The effects of Paeryungsan and Bojungchiseubtang on rats with nephrosis induced by a single intravenous injection of puromycin aminonucleoside(PAN), 2.5mg/100g of body weight were evaluated in the present study. The effects of Paeryungsan and Bojungchiseubtang on PAN nephrosis were evaluated by measuring ①the concentrations of albumin, total protein, total lipid, cholesterol, triglyceride, creatinine, blood urea nitrogen and uric acid in the serum, ②the amount of volume, protein, glucose and creatinine of the 24hours urine ③the concentration of blood in the urine, intake water, and by observing the changes of microscopic findings of kidney. The results are summerized as follows; 1. In the control group, the concentrations of cholesterol, creatinine, blood urea nitrogen in the serum, the amount of protein and glucose of 24 hours urine, creatinine of 24 hours urine and 24 hours urine volume on the 22th day were significantly increased. On the other hand, the concentration of albumin in the serum, the amount of creatinine of 24 hours urine on the 8th day, the volume of 24 hours urine and the intake water on the 8th, 15th day were decreased significantly. Electron microscopic findings were the segmental obliteration of the foot processes, swelling and villous transformations of the visceral epithelial cells and partial increase of the mesangial matrix. 2. In Paeryungsan group, the decrease of albumin in the serum and intake water were inhibited significantly. But the increase of the concentrations of cholesterol and blood urea nitrogen in the serum were inhibited significantly. And the amount of creatinine of 24 hours urine was increased significantly. There was no significant difference between Paeryungsan group and the control group in electron microscopic findings. 3. In Bojungchiseubtang group, the decrease of albumin in the serum and intake water were inhibited significantly. But the increase of the concentrations of cholesterol, total lipid, creatinine, blood urea nitrogen in the serum and the amount of protein in the 24 hours urine were inhibited significantly. The concentration of protein in the serum was increased significantly. There was no significant difference between Bojungchiseubtang group and the control group in electron microscopic findings. To conclude, PAN nephrosis was induced by a single intravenous injection of PAN 2.5mg/100g of body weight on rats. It can be inferred that Paeryungsan group has the effects of improving hypoalbuminemia in nephrotic syndrome and relieving azotemia when nephrotic syndrome is accompanied by the acute renal failure. It can be inferred that Bojungchiseubtang may improve proteinuria, hypoalbuminenia, hyperlipidemia in nephrotic syndrome. But there was no significant difference between Paeryungsan and the control group, between Bojungchiseubtang group and the control group in electron microscopic findings. So I hope that there will be further studies on the effect on the alterations of glomerular polyanion sites, and on the functioning mechanism of Paeryungsan and Bojungchiseubtang in the future.

정맥주입 전문간호사가 삽입한 말초삽입형 중심정맥관(PICC) 사용 결과에 대한 후향적 분석

박정윤,박광옥,백미경,김세라,권혜리,양수진 대한기초간호자연과학회 2004 Journal of korean biological nursing science Vol.6 No.1

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.

조동필,양세정 상명대학교 사회과학연구소 2002 社會科學硏究 Vol.15 No.-

본 연구는 1980년에서 2000년에 이르는 20년간의 한국 가계의 소득규모 및 소득구조의 변화추이를 살펴보고자 하였다. 이를 통하여 가계소득이 얼마나 증가하였고, 또 어떤 형태로 구조가 달라지고 있는지를 알고자 하며, 경제위기상황에서는 어떤 식의 변화를 겪었으며 이후 어떻게 만회되고 있는가에 대한 정보를 얻고자 한다. 자료는 도시가계연보와 비근로자가구의 소득분석을 위하여 5년마다 조사하는 가구소비실태조사 자료를 함께 사용하여 2000년 실질가격으로 환산하여 사용하였다. 분석결과 동기간 동안 가계는 소득규모에서 큰 폭의 성장세를 보였으며, 뿐만 아니라 소득 구성비에 있어서 많은 변화를 겪은 것으로 나타났다. 또한 소득불평등도 많은 변화추이를 보였다. 1997년 후반에 겪은 국가적 경제위기상황은 가계의 소득추이에 지대한 영향을 미친 것으로 나타났고, 이후 이전의 추이로 많이 회귀하고 있으나, 2000년의 자료에서는 아직 1997년의 수준을 완전히 회복하지 못한 것으로 평가되었다.

Blockade of RAGE ameliorates elastase-induced emphysema development and progression <i>via</i> RAGE-DAMP signaling

Lee, Hanbyeol,Park, Jeong-Ran,Kim, Woo Jin,Sundar, Isaac K.,Rahman, Irfan,Park, Sung-Min,Yang, Se-Ran The Federation of American Societies for Experimen 2017 The FASEB Journal Vol.31 No.5

<P>The receptor for advanced glycan end products (RAGE) has been identified as a susceptibility gene for chronic obstructive pulmonary disease (COPD) in genome-wide association studies (GWASs). However, less is known about how RAGE is involved in the pathogenesis of COPD. To determine the molecular mechanism by which RAGE influences COPD in experimental COPD models, we investigated the efficacy of the RAGE-specific antagonist FPS-ZM1 administration in in vivo and in vitro COPD models. We injected elastase intratracheally and the RAGE antagonist FPS-ZM1 in mice, and the infiltrated inflammatory cells and cytokines were assessed by ELISA. Cellular expression of RAGE was determined in protein, serum, and bronchoalveolar lavage fluid of mice and lungs and serum of human donors and patients with COPD. Downstream damage-associated molecular pattern (DAMP) pathway activation in vivo and in vitro and in patients with COPD was assessed by immunofluorescence staining, Western blot analysis, and ELISA. The expression of membrane RAGE in initiating the inflammatory response and of soluble RAGE acting as a decoy were associated with up-regulation of the DAMP-related signaling pathway via Nrf2. FPS-ZM1 administration significantly reversed emphysema in the lung of mice. Moreover, FPS-ZM1 treatment significantly reduced lung inflammation in Nrf2(+/+) , but not in Nrf2(-/-) mice. Thus, our data indicate for the first time that RAGE inhibition has an essential protective role in COPD. Our observation of RAGE inhibition provided novel insight into its potential as a therapeutic target in emphysema/COPD.-Lee, H., Park, J.-R., Kim, W. J., Sundar, I. K., Rahman, I., Park, S.-M., Yang.

Controlled synthesis of (hk1) preferentially oriented Sb2Se3 rod arrays by co-evaporation for photovoltaic applications

Park, Si-Nae,Kim, Se-Yun,Lee, Sang-Ju,Sung, Shi-Joon,Yang, Kee-Jeong,Kang, Jin-Kyu,Kim, Dae-Hwan Royal Society of Chemistry 2019 Journal of Materials Chemistry A Vol.7 No.45

<P>In this paper, we propose that the microstructural control of (<I>hk</I>1) preferentially oriented Sb2Se3 films from flat films to rod arrays can improve their photovoltaic efficiency by maximizing the carrier transport characteristics. We found that, during co-evaporation, there is a narrow substrate temperature window where the Sb2Se3 rod array can be formed with an (<I>hk</I>1) preferred orientation, thus maximizing the carrier transport characteristics. The substrate-temperature-dependent morphology of the Sb2Se3 films can be explained by nucleation and growth theory and the terrace-ledge-kink model. Dramatic changes in the (<I>hk</I>0) and (<I>hk</I>1) texture coefficients occur at 315 °C, and the critical temperature for obtaining the (<I>hk</I>1) preferentially oriented Sb2Se3 film is a substrate temperature of 315 °C. On the basis of the observed variation in the film microstructure and texture coefficient, the optimum Sb2Se3 rod array having an (<I>hk</I>1) preferred orientation is formed in a narrow range of substrate temperatures. As a result, we obtained an optimized Sb2Se3 thin-film rod array that shows effective carrier transportation. Further, the optimum fill factor, short circuit current, open circuit voltage, and efficiency of the Sb2Se3 device were observed in the Sb2Se3 rod array having an (<I>hk</I>1) preferred orientation, and the enhanced carrier transport characteristics are the main reason for the improved device properties. These results show that controlling the microstructure of Sb2Se3 allows improvements in the efficiency of (<I>hk</I>1) preferentially oriented Sb2Se3 films.</P>

Perceived Benefits of Using Telecollaboration for Pre-Service English Teachers

Se Jeong Yang 한국영어교육학회 2020 ENGLISH TEACHING(영어교육) Vol.75 No.3

The purpose of this study was to explore the perceived benefits of telecollaboration for Korean pre-service teachers of English. This study connected Korean pre-service teachers to American pre-service teachers. In a one-to-one relationship, each pair exchanged their weekly writings about the assigned topics over six weeks and shared their ideas. To explore the perceived benefits that the Korean pre-service teachers of English perceived and provide a rich description, this study focused on the five Korean pre-service teachers’ thoughts reflected in their reflective papers, their writings in the Google Sites, and the final reflection paper. Data were analyzed based on a qualitative approach using the content analysis. The results showed that the Korean pre-service teachers perceived that the online interactions with the target language speakers promoted their intercultural and linguistic competences as well as some affective domains such as confidence and motivation levels. Building upon the findings, this study provides significant pedagogical implications for instructional practices for the educators and researchers.
