  • Since depositors are motivated by returns, it is important for Islamic banks management to understand the extent that rates of return on deposits influence their customers' decision to deposit. The main objective of the study is to explore the degree of influence of conventional bank's interest rate on Islamic bank's profitability and vice-versa. It has been seen from 2005 to 2011 that the rate of interest declared on deposit by conventional banks has a negative impact on profitability of both types of banks in Bangladesh. Rate of profit declared on deposit by Islamic banks is positively related with their profit earned but negatively related with profit earned by conventional banks. We see that rate of interest declared on deposit by Conventional Banks is positively related with their deposit volume but negatively related with Islamic Bank's deposit. On the other hand, rate of profit declared on deposit by Islamic Banks is negatively related with deposit levels of both types of banks. The survey result shows that almost 85% of the respondents are choosing Islamic banks only from their religious point of view and more than 60% of the sampled Islamic bank customers are reluctant to leave the bank even if conventional banks offer better interest rates.

  • Influence of herbicide oxadiazon on soil microbial activity and nitrogen dynamics was evaluated. Soil samples were treated with oxadiazon at field and tenfold field rates and incubated. Organic amendment was added as an additional substrate for soil microorganisms. Tenfold field rate oxadiazon stimulated substrate-induced respiration (SIR) and dehydrogenase activity (DHA) in amended soil as compared to unamended soil and control treatment. Soil urease activity was not affected by oxadiazon treatment. In both amended and unamended soils, treatment of the herbicide at higher rate had not significant influence on $NH_4$-N and $NO_3$-N concentrations. Higher dose of oxadiazon was degraded in both soils, but dissipation rate in amended soil was higher than unamended soil, with half-lives ($t_{1/2}$) of 23.1 and 138.6 days, respectively. Recommended field rate did not affect microbial activity and nitrogen dynamics in soil ecosystem. Results showed influence of oxadiazon on cycling processes of nitrogen in soil was not significant however its effect on microbial activity was a tendency depending on addition of organic amendment to soil.

  • Purpose - This paper analyzes the influence of the RMB internationalization on the KRW/dollar exchange rate using an autoregressive distributed lag model. Comparing the parameter estimators from the sample period before and after the global financial crisis, we found that the RMB/dollar exchange rate has increasingly become more influential on the KRW/dollar exchange rate. Moreover, for the past several years, the Chinese government has actively utilized the financial service FTA negotiation as a measure for the RMB internationalization. This paper simultaneously considers RMB internationalization and financial service negotiations in the Korean-Chinese FTA. The purpose of this paper is to explicitly suggest a direction for the financial service negotiations in the Korean-Chinese FTA considering the effects of RMB internationalization. Research design, data, and methodology - The research plan of this paper has two parts. First, for an empirical study, this paper uses the daily exchange rate of the U.S. dollar against the currencies of the ASEAN5, Taiwan,and Korea. By using an autoregressive distributed lag model, this paper studies the influence of the change in the RMB/dollar exchange rate on changes in the local currency/dollar exchange rate in seven economies neighboring China. Our sample periods are 06/2005 - 07/2008 and 06/2010 -02/2013. During these periods, China was under the multi-currency basket system. We exempted the period of 08/2008 - 05/2010 from the analysis because there was nearly no RMB/dollar exchange rate fluctuation during those months. Second, after analyzing the recent financial service liberalizations and deregulations in China, we recommend a direction for the financial service negotiations in the Korean-Chinese FTA. In the past several years,the main Chinese financial policy agenda has surrounded the RMB internationalization. Therefore, it is crucial to understand this in the search for strategies for the financial service negotiations in the Korean-Chinese FTA. This paper employs an existing literature survey and examines the FTA protocols in its research methodology. Results and Conclusions - After the global financial crisis, the Chinese government wanted to break away from the dollar influence and pursued independent RMB internationalization in order to continue the growth and stability of its economy. Hence, every neighboring economy of China has been strategically impacted by RMB internationalization. Nevertheless, there is little empirical study on the influence of RMB internationalization on the KRW/dollar exchange rate. This paper is one of the few studies to analyze this problem comprehensively. By using a relatively simple estimation model, we can confirm that the coefficient of the RMB/dollar exchange rate has become more significant, except in the case of Indonesia. Although Korea is not under the multi-currency basket system but under the weakly controlled floating exchange rate system, its coefficient appears as large as that of the ASEAN5. This is the basis of the currency cooperation that has grown from the expansion of trade between the two countries. These empirical results suggest that the Korean government should specifically consider the RMB internationalization in the Korean-Chinese FTA negotiations.

  • This study was undertaken with the intent to describe the influence of water temperature and food concentration on the filtration rates of the Asiatic clam, Corbicula fluminea. The clams were collected at Lake Geumho near Yeongsan river, during March 2001. Food organism, Scenedesmus sp. (KMCC FC-34), was indoor-cultured in f/2 medium, and was used to measure the filtration rate of the clams. Filtration rate of the clams was measured by indirect method. Cell concentrations of food organisms were determined by direct counting cells using the hemacytometer under the light microscope. The filtration rate of the clams increased with water temperature up to circa $25^{\circ}C$. Above this temperature, the filtration rate decreased rapidly. The minimal filtration rate of the clams was recorded at $5^{\circ}C$. Thermal coefficient, $Q_10$ values at low temperature range were much higher than those at high temperature range. These results indicate the asiatic clam is more sensitive in cold water like most of marine bivalves. There was a strong reversed correlation between filtration rate and food concentration. Filtration rate of the clams was reduced as food concentration was increased.

  • 항공기의 경우 충격 및 폭발과 같은 외부 피격에 의해 수압 램 현상이 발생할 수 있다. 고변형률 변형을 동반하는 수압 램 현상은 구조 생존성에 큰 영향을 미치는 요인 중 하나이다. 복합재 구조물의 기계적 물성은 이러한 고변형률 조건하에서 급격하게 변화하기 때문에 이러한 영향성을 실험적으로 분석하는 것은 항공기 생존성 평가를 위해 반드시 필요하다. 본 연구에서는 변형률 속도 변화의 영향성을 분석하기 위해 저속 및 고속 시험조건으로 인장시험을 수행하였다. 시험결과 수압 램 발생 환경과 유사한 수준으로 변형률 속도가 증가하면 인장계수가 인장강도보다 더 증가한다. 고변형률 조건에서 인장계수가 복합재 구조물 파손의 주요 요소이므로 회귀분석을 통해서 변형률 속도 변화에 따른 인장계수를 예측하였다. 항공기 피격시 발생할 수 있는 고변형률에 대한 복합재의 기계적 물성 자료를 획득하고 분석하였다. 획득된 자료는 향후 구조 생존성을 고려한 항공기 복합재 구조 설계 및 평가에 활용가능하다.

  • This study analyzed on characteristics of the ground-water capture zone in coastal areas and mid-mountainous area according to pumping rate. For this study, it targeted Jejudo island where is the volcanic island. To analyze, MODFLOW model and MODPATH model, which are the ground-water flow analysis models, were used. As a result of research, the following conclusions could be obtained. As a result of analyzing influence of a change in pumping time upon length of capture zone, the length of capture zone in coastal area was indicated to be greater in the changing ratio compared to the length of capture zone in mid-mountainous area. Next, in the coastal area, the pumping rate and the capture-zone length are changing similarly. However, in mid-mountainous area, the length of capture zone was indicated to grow when the pumping rate comes to exceed 1,500m3/day. As a result of analyzing influence of a change in pumping time upon capture area, the tendency of a change in the area was indicated similarly in coastal areas and mid-mountainous area. Especially, it could be known that the larger pumping rate leads to the more definite increase in tendency to a change in capture area. Based on this study, it was allowed to be possibly used in the suitable pumping rate in coastal areas and mid-mountainous area of the volcano island in the future. A follow-up research is judged to necessarily analyze the influence of tubular-well group upon capture zone by additionally analyzing a change in capture zone targeting the concentrated tubular well.

  • Parametric study was performed using the SCW numerical model for evaluating the performance of the SCW. The five ground related parameters, which are porosity, hydraulic conductivity, thermal conductivity, specific heat, geothermal gradient, and five SCW design parameters, which are pumping rate, well depth well diameter, dip tube diameter, bleeding rate, were used in the study. Numerical simulations were performed for short-term (24-hour) simulation. The study results indicate that the parameters that have important influence on the performance of SCW were hydraulic conductivity, thermal conductivity, geothermal gradient, pumping rate, and bleeding rate. Overall, this study showed that various factors had a cumulative influence on the performance of the SCW, and a numerical simulation can be used to accurately predict the performance of the SCW.

  • Many researchers have, nowadays, studied on spinning which can produce highly qualified products by CNC spinning machine equipped with hydraulic devices. The products have continuous metal flow which improves fatigue life, yield point, tensile strength and hardness. This study is to investigate the influence of various working conditions on the spinnability of cylindrical cups such as feed rate(ν), feed pitch(p), angle of roller holder(α), and the inclination angle of first roller path. Through experiments the feed rate of (0.4∼0.7) mm/rev was shown to give the drawing ratio of 2.5 when the angle of roller holder was 5°, However, by increasing the angle of roller holder from 5°to 20°, the range of feed rate which can produce deeper cups became wider and the spinnability was also improved. The optimum working conditions, for the maximum formability of aluminum sheet metal as well as dimensional accuracy of spun cups, are presented and discussed.

  • Bethanidine, which is known as a sympathetic blocking agent, was injected into the vein of a dog in an attempt to investigate the influence on renal funciton. Bethanidine resulted in an increased urine flow and glomerular filtration rate, and it produced an increase of urinary sodium and potassium excretion and a decrease of reabsorption rate of sodium and potassium in renal tubules, whereas renal plasma flow showed no significant changes. After pretreatment of phentolamine, a specific alpha adrenergic blocking agent, bethanidine did not significantly increase glomerular filtration rate and diuresis, significantly increased urinary sodium and potassium excretion although the magnitudes were reduced when compared with that of bethanidine alone. In conclusion, bethanidine-induced diuresis appears to be the result of an inhibited tubuler reabsorpting of electrolytes within the kidney through its sympathetic blockade of renal nerves and of an increased glomerular filtration rate, which was caused by the constriction of vas efferense in the glomeruli.
