오차수정 모형을 이용한 한․일 철강기업의 수출가격 전략 비교
박경서(Park Kyung suh) 글로벌경영학회 2009 글로벌경영학회지 Vol.6 No.4
세계교역이 활발해지고 자본이동이 보다 자유로워지면서 환율변동 속도가 빨라지고 그 영향력 또한 증대되고 있다. 환율의 변동은 국제수지 변화를 통해 국가경제 뿐 아니라 기업의 가격전략 및 생산 활동에도 영향을 미친다. 우리나라의 철강 산업은 해외시장에서 자주 일본제품과 경쟁에 직면하기 때문에 우리나라 철강업계는 원화 뿐 아니라 엔화의 변동과 일본 철강업계의 대응전략도 수출가격 책정에 주요한 변수로 인식하고 있다. 본 논문의 목적은 한․일간 철강산업의 환율전가도를 비교하고 환율 변동에 대응하여 한․일 철강업계는 어떠한 전략을 추진하여 왔는가를 추정해 보고자 하는데 있다. 분석결과 우리나라의 환율전가도는 일본에 비해 다소 낮고 환율 상승기보다 하락기에 전가도가 높은 것으로 나타났다. As the international trade is getting vigorous and the capital movement is setting free unrestrictedly, the fluctuation of exchange rate is faster and deeper with its big impacts. The drastic movement of the exchange rate have an effects on not only the national economy but also pricing strategy and production of the enterprises. Korea’s steel companies have often competing with Japan’s in international Market. Therefore, it is necessary to research the trend of the Yen exchange rate shift and find out the responsive strategies for pricing of the Japanese firms. This paper has the objective comparing the pass-through of the exchange rate and investigating the export pricing strategies between Korea and Japan. As a result of the study, the exchange rate pass -through of the steel industry in Korea is little lower than in Japan and in its going-up periods comparing to its going-down periods as well.

In 1939 Scott and Robb-Smith proposed histiocytic medullary reticulosis as a definite clinicopathologic entity. Since their original report, approximately 60 cases have been reported in the literatures. The disease occurs in adults, and is rapidly fatal, g

Background/Aims: Intracellular cAMP or cGMP is degraded by cyclic nucleotide phosphodiesterase ( PDE) . We hypothesized that PDE inhibitors modulate the peristalsis and nerve- induced responses of the smooth muscle of the guinea pig ileum. Methods: To examine the effect of rolipram ( type 4 inhibitor of PDE) and zaprinast ( type 5 inhibitor of PDE) , we measured peristaltic amplitude, area under curve ( AUC) , and frequency of contractions from ileal preparation using the peristaltic bath. The mechanical activity of the circular muscle was measured with a clip attached, via the three sites of serosal surface, to the underlying circular muscle of intact ileum in the peristaltic chamber. In another set of experiment, muscle strips from the ileum were stimulated by an electrical field. The effects of rolipram, and zaprinast, on peristalsis and nerve- induced contraction were explored. Results: The amplitude and AUC of peristaltic contractions were significantly decreased in rolipram or zaprinast-treated group and frequency of contractions was significantly delayed in rolipram or zaprinast-treated group. The nerve- induced contraction of smooth muscle was significantly decreased in rolipram-treated group. Conclusions: These observations suggest that PDEs may play a role in the modulation of peristaltic behavior of the ileum and PDE inhibitors may be used in the treatment of hyperkinetic bowel disorders.

e-문화가 급격히 확산되고 있음에도 인터넷 익명성의 문제를 전자상거래와 결부하여 접근하는 데에는 다소 소홀한 편이다. 본 논문은 e-문화 측면의 현상들을 익명성 문제에 초점을 맞추어 배경 및 쟁점 등을 점검하고 e-문화의 핵심적 요소라 할 수 있는 익명성 문제가 전자상거래와 관련하여 어떠한 의미가 있는지를 분석하였다. 연구 결과 인터넷 익명성 문제는 긍정적ㆍ부정적 효과를 동시에 안고 있고, 익명과 실명에 대한 네티즌들의 선호도 역시 팽팽한 상태로 유지되고 있어 기업의 전자상거래 과정에서 특별히 관심을 기울일 필요가 있다. 또한 기업은 익명성 수준을 효과적으로 조정하여 쇼핑몰 운영 등 전자상거래에 반영할 필요가 있으며, 장기적으로는 현실 세계에서의 ‘자기PR 시대’의 추이가 가상 세계에 반영되는 흐름을 잘 읽고 실명 사용을 확대하여 불특정 다수의 네티즌을 충성스런 고객으로 확보해나가는 전략을 실천해 나간다.

Background: It has been reported that half of toluene diisocyanate (TDI)-induced asthma patients had persistent asthmatic symptoms even after complete avoidance. We hypothesized that new sensitization to common inhalant allergens may contribute to persistent and aggravation of asthmatic symptoms. Objective: The aim of this study is to investigate the prevalence and clinical significance of new sensitization to common inhalant allergens in patients with TDI-induced asthma. Method: Thirty-six TDI-induced asthma patients who had been followed up for more than three years were enrolled. They were classified into two groups, newly-sensitized and not-sensitized groups, according to the results of the skin-prick test and serum specific IgE antibodies to common inhalant allergens monitored every year. The clinical features, drug requirements for systemic steroids, and airway hyper responsiveness were compared between the two groups. Result: Thirteen (36.1%) of 36 patients with TDI-asthma developed new sensitization to common inhalant allergens during the follow-up periods. The mean onset time were 4.93±2.49 years. The prevalence of atopic status and allergic rhinitis tended to be higher in the newly sensitized group. The duration of asthmatic symptoms before the diagnosis was significantly longer in the newly sensitized group (P<0.05). The drug requirements for systemic steroids tended to increase after the new sensitization in the newly sensitized group. Conclusion: The development of new sensitization to common inhalant allergen in TDI-asthma may be associated with chronic persistent asthmatic symptoms. New sensitization to common inhalant allergens should be monitored regularly in TDI-induced asthmatic patients. (Korean J Asthma Allergy Clin Immunol 2006;26:213-218)

본 연구는 경기 순환론적 관점에서 철강경기의 특성 및 변동 요인을 탐색하고 향후 철강경기의 전개방향을 조망하는데 목적이 있다. 연구결과 다음의 세가지 결론이 도출되었다. 첫째, 1990년대 들어서 국내 철강경기는 종전의 경기순환적 패턴에서 벗어나 불안정한 모습을 보여주고 있다는 점이다. 둘째, 철강경기 변동의 주요요인은 철강수요, 환율, 유가 등으로 나타났다. 특히 글로벌화가 확산되면서 세계 경기가 국내 철강경기에 미치는 영향은 점차 확대되고 있다. 셋째, 외부 환경변화에 의한 경기변동을 최소화하기 위해서 국내 철강업계는 설비통폐합 등 구조조정을 시급히 추진하여야 한다. This paper aims to examine the characteristics of steel industry and to investigate the factors that contribute to steel business movement from the viewpoint of economic business cycle. In this respect, it suggests three observations and its implications. First, since the early 1990s domestic steel business cycle does not follow the traditional pattern, displaying rather unstable pattern. Second, it was found that steel business movement was strongly affected by steel demand, exchange rates, and petroleum price. In particular, with the expansion of globlization, the domestic steel business cycle is increasingly sensitive to the changes in the world business cycle. Third, the paper indicated the necessity of structural reform of domestic steel producing companies.
