This experiment was conducted as a preliminary test to invent the quick ripening process for soysauces. The bran koji extract of 2 kinds of mold (Asp. niger and Asp. sojae) was used as enzyme sources in order to improve the rate of enzymatic conversion of raw materials and shorten the ripening period of soysauces. Soybean koji (inoculated Asp. sojae) and steamed soybean were enzymatically decomposed for 8 hours at $40^{\circ}C$, pH 4-6 with stirring at a rate of 1500 rpm. After the enzymatic treatment, soysauces were fermented by 4 kinds of processes with the above-mentioned salt tolerant microorganisms inoculated. After 4 weeks, sensory evolution for these soysauces products and analysis of chemical components were carried out. The results obtained were summarized as follows. 1. Soysauces prepared from decomposed koji by Asp. niger enzyme complex showed higher extractables, such as total nitrogen, amino nitrogen, pure extract and reducing sugar, than any other procedure. Extracted amounts of each components of soysauces prepared from this process during 1 month were similar to those of soysauces made from general procedure (control) for 5 to 6 months. 2. According to sensory evaluation, soysauce prepared from decomposed koji also showed best taste and were similar to that of soysauces prepared by general method for 6 months.

Under the general maritime law, a life salvor has no claim against the person saved, and a pure life salvor has no right to compensation from the owner of the ship or its cargo. This harsh rule, which treats the salvor of life less generously than the salvor of property, has been modified by international conventions, statutes, so that life salvors may expect a reward in most cases. It is, especially, unreasonable that a prerequisite of a salvage award is that at least some of the property must be saved, because life of a person can not be compared to values of goods such as vessels and cargoes. Also it is not understandable that only pure life salvors can not expect a reward for the saving of life from the owners of the property. In the meantime, according to Article 39 of the Korean Maritime Search and Rescue Act (hereunder, KMSARA), any person who has gave assistance and rescued in accordance with a governmental officer's order may get a compensation for their time and labour. The above mentioned compensation which is stemmed from the KMSARA may play a role as a compliment for the lack of enough compensation to a life salvor. This means that even though a life salvor failed to save property, he may expect a minimum compensation from the KMSARA. However, it should be recognized that when a life salvor is entitled to both remuneration for the salvage of life and recourse of expenditures from the KMSARA, the total remuneration shall be paid only if and to the extent that such remuneration is greater than any reward recoverable by the salvor under the Korean Commercial Code and the KMSARA.

Air transport agreement can be divided into air passenger contract of carriage and aviation also of the contract of carriage. And air carriers for damages greater (1) cause reason, of (2) limit reason, (3) exemption reason. Exemption reason for the extinction of the liability for damages in our Commercial Code, the Convention and domestic law are mixed. Convention on the Commercial Code and air transport, air transport people, if it is proved and that it has taken all the measures that are needed for the prevention of damage to overdue damage of passengers, liability is waived. So what was to achieve the requirements of all the actions that are reasonably necessary in any case is a problem. Amendment has the feature that the treaty for the International Air Transport reflect in accordance with the domestic situation, while being struck by international standards encompassing land, sea and air transport, even on the system. However, Commercial Code while mainly reflect the Montreal Convention governing air carrier's liability issues on the contract of carriage, a problem which the Convention had also began to occur together. So the problem due to accept the treaty to fit the domestic situation occurs. There is a need for analysis of all of the actions that are "reasonably necessary, which is defined in the Commercial Code. If there is no claim within Value Date rotor two years to air carriers on the court for the damage caused by air transport, the responsibility of air carriers disappear, sued the period of such two years, what kind of meaning on domestic law extension and stop to be whether it is interpreted, it should be determined to do their aggressive measures for the reasonable care and accident prevention.

The Korean government enacted the Chapter 6 as of Air Transportation to the Korean Commercial Act, which was enforced in 2011, in order to treat some arguments occurred from air transportation Contracts since air transportations has rapidly increased in Korea. Air transportations has been used more in the field of international market than in the field of domestic market under it's own characteristic. Therefore, many international agreements and protocols related to the air transportations has been appeared from old times and the 1999 Convention for the Unification of Certain Rules for International Carriage by Air ("Montreal Convention") is one of them. The Montreal Convention was adopted in May 28, 1999 at International Conference of Air Law hosted by the International Civil Aviation Organization ("ICAO") in Montreal, Canada where the Headquarter of ICAO is located. The Montreal Convention has been effected from September 5, 2003 and the Korean government ratified the convention in 2007. Therefore, the Montreal Convention came in to force in Korea since 2007. This year, 2017, is the 10th anniversary year since the Montreal Convention has taken effect in Korea. However, there are rare cases that argued the Montreal Convention's scope of application and this Article examines the Korean Supreme Court's case that argued the Convention's scope of application. Thus the Article basically analyzes the case from the perspective of the Montreal Convention's scope of application and examines the Montreal Convention's articles related to the air carrier's liability and extent of compensation for damage that occurred from the international carriage by air. Also this Article analyzes the Korean Commercial Act Chapter 6, which regulated the air carrier's liability and the Article tries to make a comparison between the Montreal Convention and the Korean Commercial Act in order to draw some scheme for the betterment of Korean Commercial Act. It is the hope that the Article contribute to the improvement of Korean Commercial Act through the comparison with the chance of the 10th Anniversary of the Montreal Convention in Korea.

Corundum single crystals were grown by the Czochralski technique. Relationships between crystal quality and crystal growth factors such as pulling rate, rotation rate and temperature of the melt were investigated. Optimum pulling and rotation rate for high quality corundum single crystal growth were 4.0mm/hr, 30rpm respectively. Pore was a main defect in corundum crystal and also discussed how to remove this defect by melt temperature control. Growth direction of as grown crystals was identified with(0001). And this direction had largest growth rate. Room temperature absorption spectra were measured and discussed for Cr3+ion doped and non-doped corundum crystals.

In this paper, we propose a method to classify inverse synthetic aperture radar(ISAR) image from different target. The approach can provide efficient features for classification by the combined use of a polar mapping procedure and a well-designed classifier The resulting feature vectors are able to meet requirements that efficient features should have : invariance with respect to rotation and scale, small dimensionality, as well as highly discriminative information. Typical experimental examples of the proposed method are provided and discussed.

기후변화 연구의 주요 요소 중 하나는 온도, 강수량 및 증발과 같은 기후 요인의 변화를 연구하는 것이다. General Circulation Model(GCM)은 다양한 기후 요인의 변화를 연구하는 데 일반적으로 사용되고 있다. Coupled Model Intercomparison Project(CMIP)는 전 세계의 30여 개 이상의 기관에서 개발한 GCM의 모의 결과를 연구 및 공유하기 위해 개발되었다. 기후 연구에서 대표적으로 사용하고 있는 CMIP5의 GCM은 미래 시나리오인 Representative Concentration Pathway(RCP)를 기반으로 전망 기간의 기후요소를 예측한다. 현재 개발하고 있는 CMIP6의 미래 시나리오인 Shared Socioeconomic Pathways(SSP)는 인구, 경제개발, 생태계, 자원, 제도 및 사회적 요인에 대한 미래의 사회적, 경제적 변화에 따른 기후변화에 대한 대응을 포함하고 있으며, CMIP6의 미래 시나리오는 사회적 및 경제적 결합을 통해 기후변화에 대한 정책 영향에 대한 증진된 결과를 도출할 것으로 예측하고 있다. 따라서 본 연구는 CMIP5의 INM-CM4와 CMIP6의 INM-CM5를 사용하여 대한민국의 과거 기간(1970-2005)의 월 강수량에 대한 성능을 비교하였다. 격자형 자료인 GCM을 Inverse distance weight를 사용하여 대한민국 22개 관측소로 거리 보간을 수행하였으며, 편이보정 방법으로는 분위사상법(Quantile mapping) 방법 중 Smoothing Spline 방법을 사용하여 관측소와의 오차를 수정하였다. 산정된 강수량을 토대로 6개의 평가지표(NRMSE, Pbias, NSE, PRCP100, PRCP200, PRCP300)를 사용하여 GCM의 성능을 평가하여 INM-CM4와 INM-CM5의 성능을 비교하였다.
