The surface design in architecture plays a role as an indicator that symbolizes cultures and styles, in accordance with the course of history and the standards of the time. The surface design that determines the facade of an architectural structure allows us to have a more clear understanding about the functions, programs and structures, as well as the periodical concept of the architects than any other components of the architecture. The purpose of this paper was to examine how architectural surface designs were realized, using commonly-used materials. This study provides meaningful implications, in that it suggests common features in terms of design methodologies (between architecture and non-architecture fields), and presented new possibilities for contemporary architectural surface designs through the classification of building system methods depending on fabric properties, and through the case study analysis of architectural surface designs; in addition, the results of this study could be utilized as basic data for future studies on the possibility of the expression of surface designs across a broader domain.

Deregulation is not a matter or problem to be resolved simply by revising a law or a system in a short period of time. Rather, it should be implemented at a steady pace on the basis of a full understanding of the relationships between government regulation and the government's role, taking into account the inherent functions of the market. Moreover, arguments about government regulation and its deregulation vary according to viewpoints and approaches on the part of parties concerned. This makes it more difficult to form a consensus or reach a conclusion in recognizing and resolving the basis of problems at issue. This paper aims to review the shipping industry deregulation of major countries, to analyze Korea's situation and problems of shipping regulation, and to suggest it's improving methods. Although government regulation is a sensitive policy issue, this paper remains relatively at the basic research. Regulation problems should be tackled by interdisciplinary approach. A specific approach in regulation study could not explain exactly the causes and results of government policy

Speech and language functions are highly cognitive and human-specific features. The underlying causes of normal speech and language function are believed to reside in the human brain. Developmental persistent stuttering, a speech and language disorder, has been regarded as the most challenging disorder in determining genetic causes because of the high percentage of spontaneous recovery in stutters. This mysterious characteristic hinders speech pathologists from discriminating recovered stutters from completely normal individuals. Over the last several decades, several genetic approaches have been used to identify the genetic causes of stuttering, and remarkable progress has been made in genome-wide linkage analysis followed by gene sequencing. So far, four genes, namely GNPTAB, GNPTG, NAGPA, and AP4E1, are known to cause stuttering. Furthermore, thegeneration of mouse models of stuttering and morphometry analysis has created new ways for researchers to identify brain regions that participate in human speech function and to understand the neuropathology of stuttering. In this review, we aimed to investigate previous progress, challenges, and future perspectives in understanding the genetics and neuropathology underlying persistent developmental stuttering.

Since the computer is becoming more and more indispensible tool in every fields of the modern society, it is needed and desirable to utilize the computer as a basic tool from the very early stage of the education process. Recently Maple is gaining its popularity as a comprehensive mathematical software with its power of symbolic calculations and graphics as well as its great numerical computational ability. We demonstrate the suitability of this software as a tool for the mathematical education and presents several examples of the applications of Maple. For the middle and the high school mathematics courses, we give the application examples for the quadratic functions and their graphs, statistics, the three dimensional shapes, algebraic problems. Through the examples, we confirm that mathematical education can be much more effective and simple by using Maple. If we establish computer-assisted mathematical classes, we can draw more attention and excitement from the attendants than traditional classes and eventually improve more rapidly their problem-solving ability On the other hand, the excess of the computer-aided education give to obstacle of psychological, not to be passing over the fact.

Circadian rhythms govern a remarkable variety of metabolic and physiological functions. Accumulating epidemiological and genetic evidence indicates that the disruption of circadian rhythms might be directly linked to cancer. Intriguingly, several molecular gears constituting the clock machinery have been found to establish functional interplays with regulators of the cell cycle, and alterations in clock function could lead to aberrant cellular proliferation. In addition, connections between the circadian clock and cellular metabolism have been identified that are regulated by chromatin remodelling. This suggests that abnormal metabolism in cancer could also be a consequence of a disrupted circadian clock. Therefore, a comprehensive understanding of the molecular links that connect the circadian clock to the cell cycle and metabolism could provide therapeutic benefit against certain human neoplasias.

The CRISPR-Cas system has emerged as a fascinating and important genome editing tool. It is now widely used in biology, biotechnology, and biomedical research in both academic and industrial settings. To improve the specificity and efficiency of Cas nucleases and to extend the applications of these systems for other areas of research, an understanding of their precise working mechanisms is crucial. In this review, we summarize current studies on the molecular structures and dynamic functions of type I and type II Cas nucleases, with a focus on target DNA searching and cleavage processes as revealed by single-molecule observations.

금속 나노 입자의 표면편재 플라즈몬 공명 주파수에 영향을 미치는 금속의 유전율은 조사된 빛의 파장 값에 의존하는 함수로 표현된다. 본 연구에서는 유전율의 실수부와 허수부 값을 체계적으로 변화시킬 수 있는 가상의 금속 나노 막대를 대상으로, 이산 쌍극자 근사(Discrete dipole approximation)를 사용하여, 광학적 성질을 계산하였다. 계산 결과, 유전율 함수의 실수부가 선형적으로 감소하는 경우에는 금속의 크기가 커짐에 따라 최대 소광이 나타나는 피크가 긴 파장영역으로 이동했고, 반대로 실수부가 선형적으로 증가하는 경우에는 최대 소광이 나타나는 피크가 짧은 파장영역으로 이동함을 알 수 있었다. 허수부 값을 증가시켰을 경우에는, 실수부에 관계없이 그 값이 증가함에 따라 피크의 세기가 감쇠하는 경향을 보였다.

Purpose: North Korea is a very close country geographically and culturally, but the nation has been one of the most secretive countries in the world. However, in recent years, North Korean society has been known to rapidly change its economic environment as well as its diplomatic and political environment. Since the gaining power of Jong-un, Kim in 2012, the North Korean government has implemented a new set of economic policies. North Korea has embraced limited market systems and mechanisms that have become a part of the formal planned economy. This study is concerned with the recent changes in the market and marketing activities of the communist country. It also seeks to gain an understanding of the changing market behavior of North Korean consumers. The purpose of this study is to enhance understanding of the market environments of North Korea and to provide appropriate implications for practitioners and researchers. Research design, data and methodology: Academic access to information that can understand North Korea's reality is minimal. Therefore, this study was conducted based on a qualitative analysis of secondary data. The existing literature on North Korea, related news and reports were the basis of the analysis. Analysis of secondary data related to North Korea was the main methodology of the study. Results: The official ideology of North Korea rejected most aspects of marketing, and yet there were marketing activities in North Korea. This article focuses on the development of market and marketing activities in North Korea during the recent years. This study indirectly confirmed that the market function is being activated in North Korea, and the basic functions of marketing such as advertisement, price, and distribution are being formed. In this process, the activation of the 'Jangmadang(market)' played a significant role. Conclusions: Research shows that North Korea is rapidly developing its own market function. In addition, marketing activities such as advertising and pricing strategies seem to be unprecedentedly active. However, due to changes in the political environment, the future development of North Korea's marketing is still in flux. Efforts to improve mutual understanding through continuous research are required.

Human beings are having suffered from the unexpected climate changes which are caused by global warming leaded from air pollution. More than 3 billions of people will be forced to experience insufficient water in 2015. In Korea, over 70% of precipitation has been concentrating in Summer season. Furthermore, natural disasters has been occurred constantly all over the country. The unusual flood and drought have broken out not only victims but also, property damages. By the natural condition, the effective consuming and controlling system of water is going to be the core business field and constructing dams will be encouraged and promoted for the system. To convince the objectionable against the constructing dams, a dam exhibition center stands the very important position by being responsible for the presenting positive factors and highlighting the beneficial functions. The dam exhibition center is built as complex space combined by information center regarding water resources and visitor center for the community nearby the inundated area. Combined of the different purposes, the dam exhibition center can be confused to understand the concept and contents established in the space. To enhance the visitors' understanding contents of the dam exhibition center, the spatial composition and contents are being analyzed with existing centers and define the most effective exhibition methods between the spaces and visitors. This study will be the basic quantitative analysis data for the following design works those can get the better insight how to make visitors to get information and agreement of constructing dams effectively.
