This study is to analyze the case law on the disputes of the ex-im contract of steel bar from Yugoslav to Egypt, for which awards were made by the ICC Arbitration Court, trying to find out the characteristic approach of the tribunal toward arbitration case dealing with socialistic country, Yugoslav and Islamic Egypt. An Egyptian importer and an Yugoslavian Exporter concluded a contract, with an option to purchase an additional quantity. for the steel bar. The importer exercised this option as provided in the contract. But the exporter refused to honor the option, due to the fact that the world market price for the steel bar has gone up. As a result, the importer had to purchase the steel bar as a replacement from a Rumanian company at the price higher than the original contract. And it has initiated arbitration under the arbitration clause at the ICC Arbitration Court to claim compensation for the loss due to the price difference. CISG and ULIS were closely studied along with the Yugoslav Law to determine whether the exporter could be exempted from the liability to damages. But the tribunal denied to accept the exporter's contention. The tribunal decided that the importer was entitled to damages due to the exporter's failure to deliver the additional quantity of goods at the original price. It was due to the fact that the price increase was not extremely sudden & high enough to exceed a reasonable entrepreneurial risk and also could be taken into account when concluding the contract.

Recently, Korea had virtually reached an FTA deal with China on November 10, 2014 after the 14 rounds of negotiation during past two and half years. The two countries agreed to the FTA's 22 chapters, including products, services, investment, e-commerce, finance, communication, and other trade issues, but rice and several sensitive agricultural and fisheries products were excluded from the deal. Korea and China will remove their import tariffs on more than 90 percent of all products and more than 85 percent of imports by value within 20 years once the FTA is implemented. This paper intends to analyze the impacts of Korea-China FTA on the major industries in Daegu-Gyeongbuk region. Considering the statistics on the bilateral trade between China and Daegu-Gyeongbuk region, import tariff rates of the two countries, trade specialization indices of the major industries, and the package of Korea-China FTA deal, this study investigated the sectoral effects of Korea-China FTA on the four main industries, textiles, electrical-electronics, machinery and auto parts, and steel and iron industries in that region.

Ground granulated blast-furnace slag (GGBFS) which is by-product of steel industry has been recycled as a cement admixture though the other steel slags are used as aggregates. In this study, the electric arc furnace slag (EAFS) was used as a cement admixture after the reduction of iron oxide in the slag at the interface of molten slag and water quenching. Consequently, the reformed EAFS (REAFS) had higher grindability than that of granulated blast furnace slag. And in mortar tests, the strength properties of specimens using REAFS were 98% of plain specimens of GGBFS upto 20% replacement ratio of GGBFS with REAFS.

The objectives of this study are focusing on the issue with efficiently recycling for EAF slag as construction material such as an aggregate of concrete. This study can be classified mainly into two categories: the first section is the carbonation treatment of Electric Arc Furnace(EAF)-slag for obtaining soundness as using aggregate of concrete. And the second section is the application of carbonated EAF-slag on the mortar test to evaluate the stability and mechanical property, which is compressive strength, according to the replacement of EAF-slag on the mortar. It was known that pH of EAF-Slagle according to carbonation time decreases drastically to 7 within several sec of carbonation, and a calcite is formed on the surface of EAF slag. The formation of calcite during the carbonation process of EAF slag lead to fill at pore in the texture of EAF-Slag surface, and than the porosity of EAF-slag decreases with carbonation process. In the mortar test, compressive strength, according to the replacement of EAF-Slag to sand on the mortar, the compressive strength of mortar increased as the 50% replacement ratio of EAF slag for sand was above 10% higher than that of reference mortar according to 50% replacement of EAF slag.

In this study, the domestic supply & demand of the raw materials of 35 rare metals was analyzed categorized as four types - ores, metals, compounds and scraps. Foreign trade volumes of the raw materials of rare metals have been steadily increased, furthermore, recently trade growth rate highly exceeds GDP. The raw materials of rare metals - silicon, nickel, molybdenum, manganese, etc. - for steel industry were the most big part of the raw materials of rare metals trade, while the raw materials of rare metals for electronics industry were imported relatively small volumes less than $100 million. However systematic supply & demand management on the raw materials of rare metals for electronics industry is needed since recently growth rate per year has been remarkably high over 20%. Import volumes were about three times bigger than export scale, and most of the raw materials of rare metals were traded as a metal form.

With the vision of 'a low carbon green develop' various industrial by-products were used as replacement of cement, in order to reduce $CO_2$ emissions from the manufacturing process of cement. Blast furnace slag is one of the industrial by-products. Due to the similar chemical compositions to ordinary Portland cement, blast furnace slag have been widely used in concrete with minimum side effects. Hence, in recent years, alkali activated slag-based composites are extensively studied by many researchers. However, the alkali activator can cause a number of problems in practice. Therefore, in this study, an alternative way of activating the slag was investigated. To activate the slag without using an alkali activator, calcium sulfate dihydrate was chosen and mixed with natural recycled fine aggregate. Fundamental properties of the slag-based mortar were tested to evaluate the effect of calcium sulfate dihydrate.

The connection type of steel moment frames in the country is mostly fabricated in factories so that it is fairly ductile due to good quality control. Based on references, the domestic connection satisfies the performance limit for steel intermediate moment frames specified by the AISC. However, the current KBC2009 building code specifies various systems for steel moment frames such as ordinary, intermediate, and special moment frames while the former KBC2005 only did so for a ductile moment frame. This induces the necessity of investigating which system is appropriate in the country when the domestic connection is applied. Therefore, this study was aimed at finding a proper design method by comparing the ductile moment frame in KBC2005 and the intermediate moment frames in KBC2009. The results showed that seismic design parameters for the ductile moment frames can be reasonable for satisfying the performance objective.

Development strategies of Saemangeum New Port are as follows : First, get port terminal areas to be larger. Second, establish the strategy of investment attraction in consideration of the cargo to be handled in Saemangeum New Port. Third, attract regional cargo from such Chinese provinces as Gangso and Sandongseong so as to differentiate it from the existing ports. Finally, construct such connecting programmes as the strategy of the Hub-and-Spoke calling at ports that can make a mutual win-win competition rather than an opposing competition to attract the cargo from the existing port.

BN은 천연에는 존재하지 않는 인공재료로서 특히 섬아연광형 질화붕소인 c-BN은 다이아몬드 다음가는 고경도, 높은 열전도도를 가지고 있을 뿐만 아니라 다이아몬드와는 달리 철계금속에 대해 화학적으로 매우 안정하기 때문에 다이아몬드의 응용이 매우 제한되고 있는 철강제품의 가공공구, 내마모 코팅재료로서 주목받고 있는 차세대 박막재료이다. 최근 c-BN박막 합성에 관한 많은 연구결과들이 보고되었는데 대부분의 연구자들이 성장하는 박막 표면에 입사되는 이온 에너지 및 유량이 c-BN 합성에 중요한 인자이며, 합성된 박막은 sp2결합층(h-BN)과 sp3결합층(c-BN)이 혼합되어 있음을 알 수 있다. 그러나 기존의 이온빔보조 합성법(IBAD) 공정에서는 입사빔과 증착물질이 공간적, 시간적으로 일치되는 경우에만 입사빔의 운동에너지가 증착공정에 기여하기 때문에 입사빔의 정밀한 에너지 조절이 어렵게 된다. 그러나 음이온 빔 직접 증착법에서는 입사이온빔 자신이 운동에너지를 운반하기 때문에 에너지 조절이 정밀할 뿐만 아니라 이를 통해 BN 박막의 상 및 성장거동을 조절할 수 있게 된다. 본 연구에서는 음이온 직접 증착법을 이용하여 c-BN박막을 합성하고 이의 초기성장층의 성장거동을 조사하였다. 증착시 음이온 빔의 에너지가 Bn 박막의 결정성에 미치는 영향을 알아보기 위하여 100~500eV의 보론 음이온빔을 조사하였으며 질소원으로는 낮은 낮은 에너지 범위의 질소이온을 동시에 공급하였다. FRIR 분석결과, 보론 이온의 에너지가 증가하면 cubic 상의 분율이 증가하였으며 증착된 박막은 15nm 두께의 sp2결합층이 먼저 성장한후 sp3결합층으로의 상전이가 일어났다. 질소이온빔의 에너지는 100eV 일 때 최대 cubic 함량과 두께를 보였으며 그 이상의 에너지에서는 c-BN 박막을 sputter시켰다. AFM 관찰결과, h-Bn층은 날카롭고 방향성을 가진 침상이었으며 c-BN 층은 atomically smooth 한 표면을 관찰할 수 있었다.
