The study aimed to investigate the impact of sectoral bank credit facilities provided by commercial banks on the non-oil economic growth in Saudi Arabia. Bank credit facilities are given for nine economic sectors: agriculture, manufacturing, mining, electricity and water, health services, construction, wholesale and retail trade, transportation and communications, services, and finance sector. The study employs annual data from 1970 to 2019. The study employs the Autoregressive Distributed Lag (ARDL) approach to identify the long-run and short-run dynamics relationships among the variables. The main results reveal that the overall impact of total bank credit has a significant and positive effect on non-oil economic growth in KSA. The results revealed that the effect of bank credit on the non-oil GDP growth in the short and long run was uneven. The study finds that all sectors have a positive and significant impact in the long run, except for the agricultural and mining sectors. Likewise, all sectors have a positive and significant impact in the short run, except for construction, finance, services, and transportation & communications. As a result, bank credit facilities in different sectors have played an important role in enhancing the non-oil economic growth in the KSA.

본 논문은 국제유가 변동이 한국의 제조업 품목별 수출물가에 미치는 비대칭적 영향을 분석했다. 수출의존도가 큰 한국 기업들에게는 국제유가 변동을 수출물가에 얼마나 전가할 수 있는가의 여부가 중요하다. 수출물가에 대한 유가 변동의 전이 정도는 산업별로 다를 것이기 때문에 본 연구에서는 제조업 중 8개 산업의 모형을 각각 추정했다. 분석을 위한 모형으로 비선형 자기시차(Nonlinear Autoregressive Distributed Lag) 모형을 이용했다. 이 모형을 이용 시 국제유가의 상승기와 하락기를 구분하여 장단기 수출물가에 미치는 전이 효과의 차이를 테스트할 수 있다. 국제유가가 상승과 하락 시 모든 품목의 수출물가도 상승과 하락하는 양(+)의 전이효과가 나타났으나, 일부 품목에서는 그 영향이 비대칭적으로 나타났다. 일반기계와 수송장비 등 5개 품목에서는 단기적 비대칭성이 나타났으며, 석유 및 석탄제품과 섬유 및 가죽제품의 경우 단기적 비대칭뿐만 아니라 장기 비대칭이 나타났다. 국제유가가 1% 상승 시 석유 및 석탄제품의 수출단가는 장기적으로 0.992% 상승하나 하락 시에는 수출단가가 0.977% 하락하여 통계적으로 유의한 비대칭성이 있는 것으로 분석되었다. 따라서 이러한 국제유가가 수출물가에 주는 비대칭적 영향을 고려해 기업의 전략과 정부의 수출 정책을 수립해야 할 것이다.

연료유 비용은 컨테이너 해운 선사에 있어 상당한 비용을 차지한다. 지난 3년 간, 연료유 가격은 상당하게 증가하여 왔다. 컨테이너 해운에서 단기간에 계속적으로 증가하는 연료유 가격의 일부만이 운임애 대한 할증료를 통해서 보완되고 있다. 따라서 수익(earnings)에는 상당한 부정적인 영향을 주게 된다. 본 연구에서는 H선사의 AEX 항로에 대한 유가 및 선박 관련 자본비용에 대한 경제성 분석을 하였다. H선사의 2008년 DAYLY 척당 평균 고정비 31,818 USD 적용 시 연료유 가격이 169.35$/TON 일 때 8척 운항과 9척 운항의 항차당 운영비용이 동일하였다. 현제의 고유가 상황을 고려할 때 연료유 가격이 200$/TON이하로 형성되기 어려울 것으로 예상된다. 따라서 200$/TON이상 일 때 고정비(용선료)가 35,000$이 넘어서더라도 8척 운항 시 보다 9척 운항이 경제성이 있는 것으로 분석되었다.

Purpose - This paper aims to investigate the properties of crude oil based derivative security (DLS) focusing on step-down type for comprehensive understanding of its risk. Design/methodology/approach - Kernel estimation is conducted to figure out statistical feature of the process of oil price. We simulate oil price paths based on kernel estimation results and derive probabilities of hitting the barrier and early redemption. Findings - The amount of issuance for crude oil based DLS is relatively low when base prices are below $40 while it is high when base prices are around $60 or $100, which is not consistent with kernel estimation results showing that oil futures prices tend to revert toward $46.14 and the mean-reverting speed is faster as oil price is lower. The analysis based on simulated oil price paths reveals that probability of early redemption is below 50% for DLS with high base prices and the ratio of the probability of early redemption to the probability of hitting barrier is remarkably low compared to the case for DLS with low base prices, as the chance of early redemption is deferred. Research implications or Originality - Empirical results imply that the level of the base price is a crucial factor of the risk for DLS, thus introducing a time-varying knock-in barrier, which is similar to adjust the base price, merits consideration to enhance protection for DLS investors.

Modification of injector, oil ring tension reduction and oil pump rotor re-matching with optimization of relevant engine control parameters could drive fuel consumption reduction of HSDI diesel engine. A 5 holes injector was replaced with a 6 holes with smaller nozzle hole diameter and 1.5 k factor, and evaluated in a view of fuel economy and emission trade-offs. With introducing smaller nozzle hole diameter injector, PM(Particulate Matter) was drastically decreased for low engine load and low engine rpm. Modification of oil pump and oil ring was to reduce mechanical friction and be proved to better fuel economy. Optimization of engine operating conditions was a great help for the low fuel consumption. Influence of the engine operating parameters· including pilot quantity, pilot interval, air mass and main injection timing on fuel economy, smoke and NOx has been evaluated with 14 points extracted from NEDC(New European Driving Cycle) cycle. The fuel consumption was proved to $7\%$ improvement on an engine bench and $3.7\%$ with a vehicle.

As Korea's steel industry exports 38 percent of its total steel production, the future management environment of the steel industry will change depending on the outcome of the FTA negotiations. The overall industrial structure of the domestic steel industry depends on the rules of origin, which are directly linked to the effect of concessionary tariffs. Therefore, negotiations on rules of origin are as important as tariff liberalization for Korea's steel industry. Korea's cold-rolled and plated companies are expected to be negatively affected as the country of origin standards of steel products have not considered the steel production processes in Korea. In future FTA talks, the country of origin rules should be agreed on a change of tariff classification basis. This result would secure a stable export market through increased predictability of steelmakers and reduce the risk of increased costs of oil and intangible products. In addition, the government should consider the structure of domestic supply and demand so that it does not impose constraints on the change of tariff classification. Finally, participants in the negotiations should consider the opinions of the domestic steel industry.

In this study, based on actual data for the past 20 years, the factors affecting aviation trade were identified by classifying the countries that concluded FTAs with Korea and those that did not, through panel analysis. The amount was analyzed by dividing it into exports and imports, and differences between countries with FTAs and non-FTAs were also derived. As a result of the analysis, both exports and imports showed a positive(+) direction for the counterpart country's GDP per capita and Korea's GDP, and a negative(-) direction for the counterpart country's GDP and Korea's per capita GDP in the case of a country that signed an FTA. On the other hand, in the case of non-FTA countries, the GDP of both countries showed a positive(+) direction and per capita GDP showed a negative(-) direction. International oil prices did not show any significant results. As such, the results of the analysis of exports and imports are similar, but the difference is that the GDP variable acts in different directions between countries with and without FTAs.

By blending of various low boiling point oxygenated agents to lower grade fuels, significant improvements were simultaneously obtained in smoke, CO, PM, SOF and BSEC. Especially, our trends were remarkably obtained by retarding injection timing, by decreasing boiling point and increasing blending contents of additives in case of oxygenated agents rather than non-oxygenated agents. Also, it was revealed that when 20vo1.% DMM added to high viscosity fuels and injection timing was retarded, NOx-smoke trade off relationship was much better than that of ordinary diesel fuel. Thus, lower grade fuels with high viscosity could be expected to be used efficiently and cleanly in diesel operation by blending low boiling point oxygenates.
