Blackout game on a certain size of the Go table, which looks simple, involves a variety of mathematical modeling. This study uses a research and education method. While the mathematically gifted students were playing blackout game, the author, as the instructor, observed the ways in which they approached various mathematical models. Based on the data, this study examines the effects of blackout game on the children's cognitive processes. This study further discusses the issues of questions.

Many abstraction techniques are introduced in programming languages in order to facilitate the development, maintenance and extension of softwares. But several concepts and terms related to abstraction have not been uniformly defined and have been explained differently. Expecially in object-oriented paradigm strongly based on abstraction common consensus was not derived. In this paper, we analyse procedural abstraction, propose the taxonomy of procedural abstraction and show that procedural abstraction contains the concept of abstraction on abstraction in addition to the transformation of procedures into abstraction. We also explain polymorphism in the view of abstraction. These analysis and consideration will make it possible to understand procedural abstraction more intensively.

Since the first success of simple mastoidectomy, about 100 years ago by Schwartze (1873). Zollner (1951) and Wullstein (1952) had formulated systemically the basic principles of restorative surgery of chronic ear diseases. Although the last century has shown a remarkable advances in surgical technique, there are still lots of debatable problems yet. The authors experienced 970 cases of middle ear surgery during last four years and clinical and statistical analysis were done as a preliminary report.

Reunification and economic development are discussed as the national visions of the Korean Peninsula in the 21st century. In particular, the tourism industry must be included as one of goals pursued under these visions because tourism indeed seeks for the happiness and peace of human beings. Mt. Kumgang tour began on November 18, 1998 and a land route to Mt. Kumgang also opened on September 1, 2002. These historical events have brought huge changes in the tourism industry of South and North Korea, and over 1,000 tourists are enjoying the Mt. Kumgang tour everyday. Nevertheless, the Mt. Kumgang International Tourism Zone is still poor in tourist accommodations as well as tourism infrastructure. Legal and institutional systems as an international tourism zone have not been established, and incidental and convenience facilities are insufficient. All these problems make it difficult to operate the special zone. Thus, this study set the following objectives to solve these problems: Establish systematic theories on the Mt. Kumgang International Tourism Zone, analyze theories on external factors, factors affecting tourist accommodation expansion, and use the findings as basic materials for tourist accommodation expansion strategies.

Typography in visual communication design is 'potential form' hidden within a space. Showing rhythm in typography is making 'aesthetic sense' in a graphic which has formative characteristics, the way of expression is very important. When the rhythm is recognized through visual stream, Rhythmic Sense is formed. The research will present a new form of the Visual Rhythmic Sense by analyzing typography works out positively. First of all, I researched works done by Fillippo Marinetti, Robert Massin, Wolfgang Weingart, and David Carson for their vigorous experimentalism in typography in forming visual rhythm. I used S.D. Scale method to analyze characteristics of visual image and VARIMAX for factor analysis reaching types of visual rhythm, which could be classified as following. (1) Synesthesia Rhythmic Sense (R-synesthesia) means that the senses are conveyed through 'visualization of auditory sense' and 'visualization of touch' (2) Simultaneous Rhythmic Sense (R-simultaneity) means that the time and space co-exist in one plane. (3) Connective Rhythmic Sense(R-connection) means that different factors (Within one plane) co-exist interacting with one another and creating a unified impression through such a process. (4) Artist Oriented Rhythmic Sense ($-artist) means that the artist interprets the content subjectively and expresses his/her impression, thereby, attracting a gaze of audience systematically and arbitrarily. (5) Reader Oriented Rhythmic Sense(R-reader) avoids the existing legibility formed through aggressive engagement of the reader.

The goal of this paper is to propose the Hangul Jamo to make a optimum transmission code of Hangul consonant and vowel(Jamo). The Hangul Jamo was analyzed by three kinds of Hangul Jamo. First one is the basic Hangul Jamo which is consisted by 24ea Jamo. Second one is a two combination keyboard which has 28ea Jamo. Third one is 54 Jamo set which is added the double Jamo to the second one. Use frequency of Hangul-Jamo is analyzed based on the Hangul in "Modern Korean Use Frequency Rate Survey Result" issued by The National Institute of the Korean Language". Total 58,437 Korean words are contained in the report and the words are composed with Hangul 1,540ea. The results of this study are as follows, In the Jamo are that in the first Jamo set case, the highest use frequency consonant is "ㅇ" and the lowest one is "ㅋ", and in the vowel case, the highest use frequency one is "ㅏ" and the lowest one is "ㅑ". In the second case, the highest use frequency consonant is same as first case and the highest vowel is "ㅏ" and the lowest one is "ㅒ". In the third case, the highest consonant is "ㅏ" and the lowest one is "ㅞ". the highest vowel is "ㄱ" and the lowest one is "ㄽ".

The Maritime Labour Convention, 2006, (MLC) aimed to ensure decent working conditions for seafarers and entered into force on August 20, 2013. It was considered as the fourth pillar in the maritime sector. This paper evaluates how the MLC has been implemented in the field and what issues were addressed in the shipping industry. To achieve this, statistical analysis was conducted using inspection data of Port State Control (PSC) carried out by the Paris MOU and the Tokyo MOU during 2010-2012 and 2014-2016 for deficiencies under the MLC and International Labour Organization (ILO) No. 147 Convention. This study compared pre-2013 and post-2013 deficiency data according to ship's age, size (gross tonnage) and type. The results showed that, although the deficiencies reported by the Tokyo MOU during 2014-2016 were nearly double those from 2010-2012, the deficiency share against total deficiencies for the Tokyo MOU remained two thirds of those for the Paris MOU. This study suggests that the Tokyo MOU should strengthen its inspection efforts on MLC and ILO should provide clear references, such as guidelines and a unified interpretation for national discretions under the MLC for the purpose of harmonized PSC inspections. Additionally, it would be desirable to consolidate the deficiency coding system for the MLC by deleting the codes for the ILO No. 147 Convention, which was incorporated into the MLC. It would also be beneficial to add new deficiency codes for social security, including seafarers' leave and repatriation.
