Two of the most important topics of the 21st century are ensuring harmony between man and his environment and the emerging long-tail economy in which niche markets are becoming increasingly more important. Since the Industrial Revolution in 17th century, human beings have increasingly exploited the world's natural capital, such as the natural environment and its ecosystems. Now the world is facing limits to sustainable economic growth because of limits to this natural capital. Thus, most countries are beginning to adopt a new development paradigm, the so-called"Green Development Paradigm" which pursues environmental conservation in parallel with economic growth. Recently, the Korean government announced an ambitious national policy of Low Carbon & Green Growth for the next six decades. This is an important step that transforms the existing national policy into a new future-oriented one. The fisheries sector in particular has great potential for making a substantial contribution to this national policy initiative. For example, the ocean itself with its sea plants and phytoplankton has an enormous capacity for fixing carbon, and its vast areas of tidal flats have a tremendous potential for cleaning up pollutants from both the sea and the land. Furthermore, the fishing industry has great potential for the development of fuel-saving biodegradable technologies, and a long-tail economy based on digital technologies can do much to promote the production and consumption of green goods and services derived from the oceans and the fisheries. In order for this potential to be realized, the fisheries authority needs to develop a new green-growth strategy that is practical and widely supported by fishing communities and the markets, taking into account the need for greenhouse gas reduction, conservation of the ocean environment and ecosystems, an improved system for seafood safety, the establishment of strengthened MCS (monitoring control surveillance) system, and the development of coastal ecotourism. In addition, fisheries green policies need to be implemented through a well-organized system of government aids, regulations and compensation, and spontaneous (voluntary) orders in fishing communities should be promoted to encourage far more responsible fisheries.

It is very important for beginners in networking to build, test, and operate an IP network system, which is the key infrastructure of the fourth industrial revolution. An IP network system consists of the IP network itself, covering both the internet and underlying layers, plus the basic network system supporting fundamental network services, with a DNS, the DHCP, email, WWW, and application service systems, such as VoIP. This paper suggests an open software-based practice platform with a minimal network configuration on which beginners can practice on nearly all of the IP network system, and it presents a practice scenario and results. In addition, it adds both IP address allocation and routing table manipulation functions to the network simulator software, which will allow beginners to learn table-based datagram routing schemes in advance. This platform may be useful for networking beginners in order to practice on an IP network system on their own personal computers without additional equipment and costs.

Heritage has entered the center stage of public diplomacy in East Asia. Competition to claim and interpret memories of World War II in East Asia has driven campaigns to list heritage items with UNESCO. State and non-state actors aim to use heritage listings to present a particular view of the war and related history to domestic and international audiences. This paper highlights the role of heritage soft power in East Asia's "memory contests" by examining the promotion of dissonant modern heritage in UNESCO's heritage programs. It conceptualizes heritage designation as a soft power resource in East Asia and presents a conceptual framework for understanding the hegemonic competition over the "memory regime" that emerged from the structural change in East Asia's regional order. It then uses this framework to analyze the processes by which state and non-state actors promote and/or object to UNESCO recognition of their sites and documents as heritage of outstanding universal value or world significance. The elements of this process are illustrated with case studies of two very different pieces of heritage, Japan's "Sites of the Meiji Industrial Revolution" and China's "Documents of Nanjing Massacre," which were enshrined as significant world heritage in 2015. While state and non-state actors in East Asia are increasingly recognizing the utility of heritage as a soft power resource for advancing specific historical narratives to an international audience, a backlash movement from civil society groups and governments in other countries prevents a purely unilateral interpretation. As a result, the utility of heritage soft power in this context must be significantly qualified.

The Internet is a social and economic foundation, apparently destined for human communication and interaction. It is supposed to allow for more interactive and innovative ways for people to do what they do in 'real lift'. There is no shilly-shallying to say that at present, Internet has become a commanding and useful tool for empowerment and income making in developing countries. It is very difficult to say that at present internet has turned into a popular and useful thing among the Bangladeshi people like students, doctors, engineers, businessmen, researchers as well as politician who are being logged into the internet for getting information what they want. Though the Internet was invented in 1970 but it came late in Bangladesh through UUCPs (Unix-to-Unix copy) email connectivity in 1993 and IP connectivity in 1996. Having launched Internet, on June 1996 National polls result were broadcast through the using of World Wide Web (WWW) that was the first ever practice trial in Bangladesh. On June 1996, the government has approved to allow VSAT (Very Small Aperture Terminal) in the country's private sector to operate as Internet Service Provider (ISPs). At the end of year, there were only two ISPs in the country and number of users near about one thousand only. But next year in 1997, the total number of ISPs was more than a dozen and the clientele growth was ten times higher than that of the previous year. From then, the number of Internet users and ISPs are increasing significantly in Bangladesh. About 40 ISP are providing internet service among as many as 3, 20,000 users at present out of almost 130 license holder ISP provider but among the ISPs, most of the ISPs are placed in Dhaka and few are working in Comilla, Sylhet, Rajshahi, Chittagong and Khulna. It should be mention that currently, broadband internet (Radio, Cable) connection is working side by side dial -up connection where broadband accounts 10,000. This paper will have a comprehensive discussion on the current situations of Internet and some of the contemporary issues in the matter concerned.

This paper examines the transition of the Hungarian men's costume. Transition of the Hungarian men's costume can be divided into pre-eighteenth century, eighteenth century, and since the nineteenth century. Hungarian costume was derived from the Magyar who settled in Hungary in the ninth century. Hungry had begun to accept Western culture in the tenth century, so when the prototype of Hungarian costume was completed, it consisted of Dolman, Mente, pants, and boots combining traditional Magyar style with Western European style. In particular, Dolman shows the uniqueness of the Hungarian men's costume; it has a high, stand-up collar in the back center, closes on the left, has a right front plate with a diagonal cut at the waist, and a wide front closure. In the eighteenth century, Hungarian men's costumes played an important role in displaying national pride while living under the oppression of the Habsburg Empire. In particular, Dolman was worn as a uniform at the battle of independence (1703~1710). This dress of male courtiers became the distinctive style of the eighteenth century and then became the basic style of men's costumes. Since the nineteenth century, Hungarian men's costumes have acted as an means to promote the national consciousness of Hungary through the Citizen Revolution (1848), the War of Independence (1849), and the formation of the Dual Empire (1867). Looking at evolution of the Hungarian men's dress style, it reveals that resistance and struggles against other nations, a history of aggression, and living under oppressed are factors that impact on important clothing transitions.

The aim of this study is to shed light on essentials of Suprematist artists focusing on Malevich and their works in relation to modem design, and to examine their roles in the modem design industry compared to those of modem designers. The study obtains the following result on Suprematist artists and their works in Russian avant-garde in terms of modem design. Firstly, Suprematist artists had a great deal of interest in practical design although it seemed Suprematist were replaced by utilitarianism in avant-garde during the Russian revolution. Secondly, Suprematist artists were the first artists to bring the birth of modem design trends by applying their art in geometric forms to clothing and fabric design as well as ornaments and handicraft. Thirdly, the artists' attempt to work with needle workers made it possible to set achievements in design and modem decorative art exhibitions in various fields of art-life. As for the role of modem designers, Suprematist artists including Malevich have significant meanings as follows: Firstly, Malevich was a creative, future-oriented artistic designer who realized zaum of painting on the stage and created suprematistic mode in a cosmic point of view in order to agree with the environment. Secondly, Suprematist artists knew the importance of works that were produced by craftsmen and worked together with them. Therefore, the designers could maintain fabric decoration in difficult conditions knowing the importance of the high value-added industry. Thirdly, they were artists in real life who embodied the ideas and theories of Suprematist in sample works by recognizing the need of changes in life environment: they planned to set a new visual world in art but did not confine the idea only to painting.

The eighteenth century in Great Britain was the period of transformation, Great Britain externally experienced several wars intermittently mid internally transformed into the industrial country in the course of the 18th century. British shipowners were faced with short of seamen mainly due to several wars and expansion of shipping tonnage British shipowners tried to solve the mooing problem by decreasing the number of seamen from 22-23 sailors per ship of 100 tonnage in 1710's to 5 in 1810 and increasing seamen's wage from shillings per common seaman per month in the 17th century to 25 shillings in the middle of the 18th century and equation omitted during the French Revolutionary and Napoleonic Wars. What caused and resulted by specialized shipowners to cope with changeable market situation with flexibility was decrease of the number of seamen per ship and increase of wage.

Ibuprofen, non-steroidal anti-inflammatory drugs; NSAIDs, is a highly crystalline substance with the pharmaceutical properties of poor solubility and low bioavailability. The size reduction of ibuprofen is needed to improve the solubility. The objective of this study is to optimize the grinding condition of ibuprofen. Grinding of ibuprofen was carried out using a planetary mill. Grinding parameters were optimized using Box-Behnken experimental design method. The physical characteristics of ground ibuprofen were investigated for the particle size by particle size analyzer, for the crystal size by X-ray diffraction (XRD), and for the tensile strength by tensile/compression tester. The optimum conditions for the milling of ibuprofen were 290 rpm of the revolution number of mill, 24.6 g of the weight of sample, and 10 minutes of grinding time. The measured value of the particle size of ground ibuprofen at these optimum conditions was $13.5{\mu}m$. The results showed that the crystal size of ibuprofen was reduced by the planetary milling process. In case the relative density of the tablets formulated of ground ibuprofen was range of 0.85~0.90, the tensile strength of them was range of 1$2{\sim}14Kg_f/cm^2$.

The importance of mathematics is increasing as human beings are entering the 4th industrial revolution era from the information society. In response to this trend, the government is also paying a lot of attention to math education by addressing 2012 mathematics education as 'the year of mathematics education.' However, many students are still suffering from mathematics and they feel math is difficult and even give up math. For this cause, students who give up math are showing up a lot in middle and high schools. For these math low achievers, the government, educational institutions, research institutes, and schools are creating and implementing a lot of programs. Among these programs, there is also a program called Math Clinic counseling. However, most of these math clinic counseling end up in a one-time events or are not linked to class because counselors and math teachers are different. So, this research focuses on this fact : gap between math clinical counseling and real mathematics class. The study analyze the reasons of the cause of low level of self-confidence in math and high level of math anxiety from the students. And it suggests some strategies for the individual students base on their difficulties. Applying these strategies to the students, the study mainly focused on how the strategies are presented in real class by observing practical classes.
