The vessels which are operated in ECA (Emission Control Area) after $1^{st}$ January 2016 shall be complied with revised NOx emission requirement (Tier III). Effective solutions for NOx emission requirement are SCR (Selective Catalytic Reduction), EGR (Exhaust Gas Recirculation) and Installation of LNG Dual Fuel Engine. This study is considered the design modification as per application of LNG Ready notation. In case of LNG Ready - S notation, the vessel shall be retrofitted the Main engine with Dual fuel engine and LNG Fuel system after delivery. On this paper, the entire process for design modification was explained to meet the requirement for LNG Ready notation.

This study examines the examples and changes of wooden member terms in Yeonggeon-euigwe(營建儀軌) in the era of Joseon Dynasty. As a result of examining examples, about 240 wood member terms were found on the basis of phonetic value and examples different from today's term use were also confirmed. Wood member terms were derived in variety and synonym and different style, that is, coexistence or transition of several notations as the term indicating the same member was found. Derivation of detail terms has the characteristic increasing on the basis of morpheme and formation of different notation followed Chinese notation or was caused by complex coinage features like a coined word of Korea by the meaning of a word and borrowed character notation borrowing sound and it is also related to the specificity of that time which had dual language system. The typical examples without different style for long were pillar, rafter, door and window. Examples with active generation and selection of different styles included beam, capital and bracket-system terms. Different styles were caused by the combination of several notations including borrowed character in the process of Chinese character notation borrowing sound, Korean unique character emphasizing and limiting combination of 木 (wood) with side of character and Chinese. Period showing remarkable change of example notation was the compilation of ${\ll}$the Hwa-Sung-Sung-Euk-Eui-Gue${\gg}$ 華城城役儀軌. ${\ll}$the Hwa-Sung-Sung-Euk-Eui-Gue${\gg}$ is the representative type uigwe made by printed type not by handicraft. Printing by type accompanies unification of the shape of a character necessarily and it was considered that it resulted in the unification of character of different style, the number of strokes and minute difference of strokes, and it was interpreted that common use of intentional notation with the unification of the shape of a character was achieved.

본 연구에서는 프로젝션 TV와 컴퓨터 화면에 제시되는 일본어 영상문자 읽기 수업을 위한 적합한 화면 환경을 살펴보았다. 그리고 복수표기, 띄어쓰기 등 실제 일본 웹 사이트에 나타나는 일본어 표기 형식에 대한 사전 학습활동이 웹 문서의 내용 파악에 어떠한 영향을 미치는지를 실험을 통해 살펴보았다. 실험 결과 제7차 교육과정에 새롭게 추가된 일본 웹 문서의 독해 능력을 배양하기 위하여 두 가지 조치가 필요함을 알 수 있었다. 단기적으로는 실제 일본어 웹 사이트의 문서를 학습 자료로 활용할 필요가 있으며, 장기적으로는 현행 일본어 교과서의 표기 형식을 재검토할 필요가 있음을 확인할 수 있었다.

Wiener filtering method was applied to the dual energy imaging procedure in digital radiography(D.R.). A linear scanning photodiode arrays with 1024 elements(0.6mm H 1.3mm pixel size) were used to obtain chest images in 0.7 sec. For high energy image acquisition, X-ray tube was set at 140KVp, 100mA with a rare-earth phosphor screen. Low energy image was obtained with X-ray tube setting at 70KVp, 150mA. These measured dual energy images are represented in the vector matrix notation as a linear discrete model including the additive random noise. Then, the object images are restored in the minimum mean square error sense using Wiener filtering method in the transformed domain. These restored high and low energy images are used for computation of the basis image decomposition. Then the basis images are linearly combined to produce bone or tissue selective images. Using this process, we could improve the signal to noise ratio characteristics in the material selective images.

This paper examines 'Religion Class' in the scheme of the DDC. The major findings of the study are summerized as follows. 1. The first edition of DDC was published in 1876 in order to classify Amherst College Library collections. In spite of the continuous study and revision of the experts, the frameworks of the DDC systems are still kept unchanged. Only their subdivisions, reflecting those developments in the academic world, are developed and detailed more sophisticatedly. 2. The division of 200 does not function as generalities for all class of religion. Therefore, it is necessary to amend the division of 200 to serve generalities for all the religions of the world. 3. Standard subdivision for the christian religion and for the non-christian religion is different. So, the mnemonic nature has become weakened due to the dual standard subdivisions and the classification number becomes much longer and complicated. Therefore, one standard subdivision for all religions of the world is required. 4. Religion science was organized in late 19 C and developed continuously, but the DDC does not accomodate the religion science as a science. Accodingly, the DDC should be revised recognize religion science as a science not the christian science. 5. The deployment of classification scheme in Dewey's 200 is severely biased. That is to say, 9 division were assigned for christian religion, whereas only 1 division was assigned for non-christian religion. Therefore, an adjustment should be made to allocate subdivisions equally to all religions of the world. 6. General classification order of religion is prehistoric, primitive, ancient, modem and world religion in religion science. But, DDC does not accept this general classification order of religion, sticking to the biased expansion towards christianity. Therefore, DDC must adopt the general classification order of religion in the religion science. 7. Lastly, because of the limitation of decimal notation in DC, DDC does not accomodate new subject equally and classification number becomes longer. Therefore, centesimal expansion is proposed in order to make the classification number short, to enlarge its capacity of inclusion of new subject and to maintain consistency in the scheme.
