The APT(Asia Pacific Telecommunity) Standardization Program(ASTAP) as means of regional cooperation in standardization was launched on February 1998. Its major functions are to study standardization-related issues and make contributions to the international standardization organizations like ITU, to bring about harmonization of telecommunications standards for the region and to disseminate information on regional and international standardization activities .In addition, through the third ASTAP Forum of the APT which held at Seoul on June 2000, its organizational structure was changed and focused on the creation of more productive outputs and the more active participation of industry-related organization, for the pursuit of regional common interests and the enhancement of regional positions toward international standardization arena. Bearing in mind the consideration outlined above, this paper aims to analyze telecommunications standardization policy and current issues intended by Asia-Pacific regional standardization organization and accordingly, to suggest a strategy for strengthening telecommunications standardization activities in Asia-Pacific region.

There have been researches on game continuance intention based on consumer behaviour theory of management science. Such macro access of computer game analysis might be insufficient to draw valuable results due to complex subsystem structure of recent computer games. In this paper, we choose 'Blade and Soul' game that was first published in 2012 and has been within top 20 MMORPG in Korea but known as a 'long time users' only game'among game players recently. Three user groups - long loyalty, concentrated, casual - are classified based on their play history and play time per day of Blade and Soul. The first survey with 222 subjects revealed that the real strength of the game was not the combat - Dungeon, Arena, Battleground competition - but very cohesive game community Blade and Soul has. Thus, we conduct another survey on the game community issues among 148 long time users (over 3 years playing history) and analyze their traits and behaviour patterns.

In this paper, we describe a developmental system for establishing personal information tendency based on user queries. For each query, the system classified it based on the category information using a kNN classifier. As category information, we used DDC field which is already assigned to each record in the database. The system accumulates category information for all user queries and the user's personalized feature for the target database. We then developed a personalized retrieval system reflecting the personalized feature to produce search result. Our system re-ranks the result documents by adding more weights to the documents for which categories match with the user's personalized feature. By using user's tendency information, the ambiguity problem of the word could be solved. In this paper, we conducted experiments for personalized search and word sense disambiguation (WSD) on a collection of Korean journal articles of science and technology arena. Our experimental result and user's evaluation show that the performance of the personalized search system and WSD is proved to be useful for actual field services.

This paper examines the American role in shaping South Korean nation-building during the early Cold War by considering how the United States attempted to form South Korea's education and how Koreans responded to these efforts. It looks at education as an arena where "American" ideas such as democracy and liberalism were received, transformed, and utilized by Koreans. This study pays particular attention to the gap between American intentions and Korean expectations, as well as to the competition between American and Japanese systems, which explains the contradictory role America played in South Korean nation-building. In order to better assess the role of the United States in shaping South Korean education, this article considers the complex dynamics between the Japanese legacies, American influence, and Korean actors. Americans had exerted a great effect on Korean education since the beginning of their relationship. American missionaries, U.S. military government, and educational mission teams had all contributed to the expansion of educational opportunities for Koreans. Through the educational institutions that they established or helped establish, Americans tried to spread "their" ideas. In this process, Americans had to struggle with two obstacles: Korean nationalism and the legacies of Japanese colonialism. Many Koreans used American missionary schools for their own purposes and resisted U.S. military government's policies which ignored their desire for self-determination. American education missions had limited effect on Korean education due to the heterogeneous Japanese system that was still influencing South Korea even after liberation. The ways in which Americans have influenced the democratization of South Korea have not been simple. Although "American" democratic ideas reached Koreans through various routes, Koreans understood the "American" idea within their own historical context and in a way that fit their existing socio-political relations. Oftentimes suspicious of "American" democracy, Koreans developed their own concept of democracy. The overall American influence on Korean democratization, as well as on Korean education, was important but limited. While Americans helped Koreans build educational infrastructure and tried to transfer democratic ideas through it, Koreans actors and Japanese colonial legacies limited its impact.

Seoul's One Less Nuclear Power Plant is the major urban energy policy launched in April 2012. Its effort to respond to climate change and energy crisis in the aftermath of the Fukushima nuclear accident turned out very successful, considering huge decrease of energy consumption. However, the question of how the cut of energy consumption was possible remains unanswered. This paper introduces the concept of urban governance capacity as the cause of the success. It is the managing and governing capability to maintain the logical consistency policy system, comprising of policy perception, goals, policy tools and evaluation. Without this logical correspondence between the policy factors, any system including energy regime easily falls apart during the systemic transitional period. Governance capacity provides the integrating framework, so that the system as a whole maintains the internal homeostasis.

The fungal products dibenzodioxocinones promise a novel class of inhibitors against cholesterol ester transfer protein (CEPT). Knowledge as to their biosynthesis is scarce. In this report, we characterized four more dibenzodioxocinones, which along with a previously described member pestalotiollide B, delimit the dominant spectrum of secondary metabolites in P. microspora. Through mRNA-seq profiling in $g{\alpha}1{\Delta}$, a process that halts the production of the dibenzodioxocinones, a gene cluster harboring 21 genes including a polyketide synthase, designated as pks8, was defined. Disruption of genes in the cluster led to loss of the compounds, concluding the anticipated role in the biosynthesis of the chemicals. The biosynthetic route to dibenzodioxocinones was temporarily speculated. This study reveals the genetic basis underlying the biosynthesis of dibenzodioxocinone in fungi, and may facilitate the practice for yield improvement in the drug development arena.

Recently Deep Learning technology, one of the fourth industrial revolution technologies, is used to identify the hidden meaning of network data that is difficult to detect in the security arena and to predict attacks. Property and quality analysis of data sources are required before selecting the deep learning algorithm to be used for intrusion detection. This is because it affects the detection method depending on the contamination of the data used for learning. Therefore, the characteristics of the data should be identified and the characteristics selected. In this paper, the characteristics of malware were analyzed using network data set and the effect of each feature on performance was analyzed when the deep learning model was applied. The traffic classification experiment was conducted on the comparison of characteristics according to network characteristics and 96.52% accuracy was classified based on the selected characteristics.
