무위험 금리평형의 불균형: 금리․환율 개별 충격의 동태효과 분석

김윤영(Yun-Yeong Kim) 한국계량경제학회 2010 JOURNAL OF ECONOMIC THEORY AND ECONOMETRICS Vol.21 No.2

본고에서는 외환위기 이후 우리나라의 무위험 금리 평형조건 (covered interest rate parity)의 불균형 오차 (disequilibrium error)와 국내외 금리 및 현ㆍ선물환율 개별충격과의 동태적 상관관계를 살펴보았다. 이를 위하여 김윤영⋅박준용 (2008), Kim(2008, 2009), Kim and Park (2008), 김윤영 (2009)을 따라 무위험 금리평형을 구성하는 변수들을 개별적으로 모두 고려한 VAR 모형에서 유도된 변환 오차수정모형을 도입하였다. 충격반응, 그랜저 검정 등의 분석 결과 2000 년대 들어 우리나라의 무위험 금리평형 불균형 오차는 환율 보다는 주로 국내외 금리 부분에서의 충격에서 유발되는 것으로 나타났다. 또한 국내외 금리 및 현ㆍ선물환율 간의 장기 공적분 관계의 추정계수로 정의된 불균형 오차를 이용하여 동일한 동태분석을 실시한 경우와 구조모형의 식별 순서를 바꾼 경우에도 유사한 결과가 도출되었다. 그러나 무위험 금리평형 불균형 오차가 금리와 환율 변수에 미치는 영향은 분석 방법에 따라 상이하게 나타났다. 따라서 우리나라의 경우 환율ㆍ외환 정책 보다는 통화정책이 더 무위험 금리평형의 불균형을 유발하는 요인이 될 수 있으므로 통화당국의 기준금리 결정시 이를 고려해야 할 것으로 판단된다. This paper analyzes the dynsmics and determinants of disequilibrium error in the covered interest parity (CIP) thrpough the transformed error correction model following Kim and Park (2008), Kim (2008, 2009), Kim and Park (2008) and Kim (2009). According to the dynamic analyses including impulse response analyses and Granger causality test, I found the CIP disequilibrium error may be mainly caused not by the foreign exchange rate part but by the domestic and foreign interest part. However the dynamic effect of the CIP error to the interest rates and exchange rates was not meaningful. These results imply that there may be restrictions to hinder the arbitrage transaction to clear the CIP disequilibrium quickly. A restriction to this direction is the credit risk of Korean financial market and any policy reaction to reduce it may be necessary. For instance, any effort to inform the sound fundamentals of Korean economy in the international financial markets may be useful.

鉛中毒에 있어서 高麗人蔘根 및 甘草根 水浸液의 解毒?果에 관한 硏究

金潤榮 中央醫學社 1983 中央醫學 Vol.45 No.4

The weaning practice of 150 infants aged from 3 months to 3 years was investig-ated by interviewing their mothers and by using a-series of questionnaire during the :period of July 25 through August 4, 1983. The study was conducted in An-bong City. Kyung-Buk, Korea and the results were as follows; 1. 50.7% of the infants were .breast-fed, 29.4% were bottle-fed, and 19.9% were mixed-fed before weaning. 2. 80% of the infants were practiced with weaning with 6 months after birth. 50% of total were continued weaning through 12 months old and 44.8% were through 13 to 18 months. 3. The first given supplementary or weaning foods were Yogurt: 23.3% Milk; :14.6% Gerber; 13.4% Cerelac; 12.7%. Mothers were much concerned about the supplementary foods and were very sen-sitive to their infants responses. Although the cereal foods were the chief supplementary (27. 3%), they were pre-pared together with other additional foods. 4. Mothers with higher education, younger age showed greater concerns about the weaning practice for their infants.

필용방감길탕이 기도 뮤신의 분비, 생성, 유전자 발현 및 점액 과다 분비에 미치는 영향

김윤영,민상연,김장현,Kim, Yoon Young,Min, Sang Yeon,Kim, Jang Hyun 대한한방소아과학회 2014 대한한방소아과학회지 Vol.28 No.2

Objectives In this study, the author tried to investigate whether piryongbang-gamgil-tang (PGGT) significantly affect in vitro airway mucin secretion, PMA- or EGF- or TNF-${\alpha}$-induced MUC5AC mucin production / gene expression from human airway epithelial cells and increase in airway epithelial mucosubstances and hyperplasia of tracheal goblet cells of rats. Materials and Methods For in vitro experiment, confluent RTSE cells were chased for 30 min in the presence of PGGT to assess the effect of PGGT on mucin secretion by enzyme-linked immunosorbent assay (ELISA). Also, effect of PGGT on PMA- or EGFor TNF-${\alpha}$-induced MUC5AC mucin production and gene expression from human airway epithelial cells (NCI-H292) were investigated. Confluent NCI-H292 cells were pretreated for 30 min in the presence of PGGT and treated with PMA (10 ng/ml) or EGF (25 ng/ml) or TNF-${\alpha}$ (0.2 nM) for 24 hrs, to assess both effect of PGGT on PMA- or EGF- or TNF-${\alpha}$-induced MUC5AC mucin production by ELISA and gene expression by reverse transcription-polymerase chain reaction (RT-PCR). For in vivo experiment, the author induced hypersecretion of airway mucus and goblet cell hyperplasia by exposure of rats to $SO_2$ during 3 weeks. Effect of orally-administered PGGT during 2 weeks on increase in airway epithelial mucosubstances from tracheal goblet cells of rats and hyperplasia of goblet cells were assesed by using histopathological analysis after staining the epithelial tissue with alcian blue. Possible cytotoxicities of PGGT in vitro were assessed by examining LDH release from RTSE cells and the rate of survival and proliferation of NCI-H292 cells. In vivo liver and kidney toxicities of PGGT were evaluated by measuring serum GOT/GPT activities and serum BUN/creatinine concentrations of rats after administering PGGT orally. Results (1) PGGT did not affect in vitro mucin secretion from cultured RTSE cells. (2) PGGT significantly inhibited PMA-, EGF-, and TNF-${\alpha}$-induced MUC5AC mucin productions and the expression levels of MUC5AC mRNA from NCI-H292 cells. (3) PGGT decreased the amount of intraepithelial mucosubstances and showed the tendency of expectorating airway mucus already produced. (4) PGGT increased LDH release from RTSE cells. However, PGGT did not show in vivo liver and kidney toxicities and cytotoxicity to NCI-H292 cells. Conclusion The result from this study suggests that PGGT can regulate the production and gene expression of airway mucin observed in diverse respiratory diseases accompanied by mucus hypersecretion and do not show in vivo toxicity to liver and kidney functions after oral administration. Effect of PGGT with their components should be further studied using animal experimental models that reflect the diverse pathophysiology of respiratory diseases through future investigations.

1. Objectives: In this research, job and stress of the staffs who is working on clinical trial of oriental medicine involved in the project of Korea Institute of Oriental Medicine (KIOM) was identified. And an efficient way to enhance the working ability of clinical trial of oriental medicine was developed by recognizing the relationship of job satisfaction, organizational commitment and job performance with their stress. 2. Methods: A survey was conducted on 18 staffs in 12 hospitals who is working in the project of The construction of constitutional information collecting system for the scientification of Sasang Constitution. The collected data was analyzed with computer software of SPSS 17.0 3. Results: The research results are as follows: 1. The staffs of clinical trial of oriental medicine responded that they want to receive the rewards for their work with a salary, and they felt that through clinical demonstration followed by SOP and front face photograph are the most difficult works in clinical trial of oriental medicine. 2. Permanent workers showed higher organizational commitment than temporary workers in the relationship of job satisfaction, organizational commitment and job performance with general characteristics(p=0.026). 3. In the relationship of job stress with general characteristics, the workers who are higher than college graduates had dissatisfaction in salary with the highest frequency(p=.004), and the workers whose monthly salary is higher than 2 millions won showed the lowest job stress(p=.021). 4. In the relationship of job satisfaction, organizational commitment and job performance with job stress, as job apprehension stress is increased, job performance is dramatically decreased(p=.027). And as improper salary stress is increased, job satisfaction and organizational commitment is dramatically decreased (p=.018, p=.050). 4. Conclusions: It was clearly evidenced that job satisfaction, organizational commitment and job performance is closely related with stress of the staffs who is working on clinical trial of oriental medicine. And it is highly recommended that the improvement of working condition and the decrease of job stress can enhance the working ability of them.
