$MgB_2$ doped with $TiO_2$ was prepared by the in-situ solid state reaction to study the effects of $TiO_2$ dopant on the flux pinning behavior of $MgB_2$ superconductor. From the field-cooled and the zero-field-cooled temperature dependences of magnetization, the realms of vortex-glass and vortex-liquid states of $TiO_2$-doped $MgB_2$ were determined in the H-T diagram (the temperature dependence of upper critical magnetic field and irreversibility line). The critical current density was estimated from the width of hysteresis loops in the framework of Beam's model at different temperatures. The results indicate that nano-scale $TiO_2$ inclusions play a role of the effective pinning centers and lead to the enhanced upper critical field and critical current density. It is suggested that the grain-boundary pinning mechanism is realized in $TiO_2$-doped $MgB_2$ superconductor.

This study aims at comprehending the characteristics of fashion communications through case study about an art marketing that Prada develops in the field of modern fashion and providing theoretical materials on creativity-based art marketing and communication spread as expression strategy for brand philosophy and personality. For its research method, theoretical study was reviewed about art marketing and Prada's fashion philosophy and then cases on Prada's art marketing were analyzed according to their types. Prada's types in their art marketing are classified into several groups: support of art foundation and artists, differentiation via flagship store, application of image fashion, exhibition project, and cooperative work with different realms. From the above marketing strategies, we can find the values in that the brand image imbedded in enterprises with culture and art was contributable to set up the brand identity, that they were much beneficial to continuous activation for fashion culture and art fields, and that fashion communications of artistic emotion based on challenge and innovation were proposed. This fashion communication in Prada via way of art marketing is not just expression of Prada's luxury fashion brand but willingness to make their unique style from different facades. This also suggests the orientation that modern fashion should look forward to in finding a new way through cooperative relationship with other fields.

By the year 2050, the world population is set to increase to 9 billion people, of which 66% will be living in cities. It is argued that this will inevitably lead to further urban densification and soaring, inhumane and dense vertical environments. However, innovative and disruptive technologies impacting all realms of life means that we will also live, work, play, learn and make in novel ways, the beginnings of which are already becoming evident. These present opportunities for reimagining city environments, and in particular tall buildings, with a focus on reducing redundancies and re-appropriating existing buildings, creating novel hybrid environments, incorporating green and social democratic spaces, and integrating multiple modes of transport. This paper examines how vertical cities may perhaps be dense, resource efficient, and yet humane, presenting three possible scenarios for Singapore's context, which are, however, common to many Asian high-density urban environments. The scenarios presented are the outcome of Final-Year Thesis Projects undertaken by final-year architecture students at the National University of Singapore (NUS) in 2017.

The aim of this study is to propose the effective management plan for (New) Library at International Science Business Belt in Korea. For this purpose, this study analyzed cases of domestic and overseas libraries which have been providing the special Science Business Service. Also user questionnaire surveys were conducted for the user demand in (New) Library. Based on case studies and user surveys, the management plan for ISBL was suggested as follow with its division into five realms; that is, information resources and special programs, manpower, space facilities, internal cooperation and international network. The research could be used as basic resources for the International Science Business Library in Korea.

In round numbers the 100 strains of entomopathogenic nematodes were isolated through the investigation of cultivated including the ginseng forming cultivated and forest soil samples by silkworm trap. The 28 strains of nematodes were selected among the isolated entomopathogenic nematodes that were confirmed the pathogenicity against Holotrichia morosa, Hoiotrichia diomphalia and Ectinus sericeus, the pest of korean ginseng and silkworm. Pathogenicity of the 2025, 2027, 2028, 2034, 2039 and 2057 strains was excellent. Selected entomopathogenic nematodes are classified of two species by morphologiacl and molecular studies, which were Sterinernma carpocapsae sp. and Diplogaster lethier sp.. Diagnostic characters include body length, lateral field pattern, tail shape and so on. The DNA sequences of the ITS region of rDNA shows similar to S. carpocapsae and .D. lethier. Isolated entomopathogenic nematodes were demonstrates that are quite within the realms of possibility for biological control agents of the pests of Korean Ginseng.

The purpose of this study is to propose a supplement to current freight demand model by analyzing factors that influence the generation of empty truck movements in regional and urban realms. To achieve this, we examined the relation between the number of empty truck trips and various generators such as truck attributes, origin type and attributes, destination type and attributes, and commodity type. We structured the ordered logit model using 2011 Korea Transport Database (KTDB) data to analyze the generator characteristic of empty truck movements in regional and urban settings. According to the results, the characteristics of regional and urban empty truck movements differed depending on truck attributes, origin type and attributes, destination type and attributes, and commodity type.

This paper deals with 'men facing limits of lives' from a perspective of struggle for social recognition. Men facing limits of lives in this paper indicates activists who have dedicated to labor movements since 1970s, and struggle for social recognition means to fight to acquire recognition in terms of love, rights and values, from members of societies. This paper analyzes the process of their failure and frustration in pursuing passion for recognition. They formed democratic labor unions, as an effort for recognition, and this led to foundation of progressive parties. Nonetheless, they are standing on a crossroad between lethargic and depression, while they are pursuing reformation and revolution. Why is their passion cooled down and depression aggravated? This paper argues various rifts both in internal and external realms of labor activists as critical factor of the failure, and suggests communication to heal the rifts as an alternative.

Recently 'Fair Society' has been a hot issue, which this study analyzes with the perspective of Michael Walzer's 'art of separation.' On the basis of this analysis, the reality of today's Korean society is diagnosed and prescribed. First, the essay theoretically delineates what 'Fair Society' would be according to 'the art of separation,' showing the working principles within and among the separated public and private spheres. Under the light of this 'Fair Society,' it argues, our society is not going through 'retrogression into totalitarianism.' Instead Korean society is, it diagnoses, disfigured by inappropriate private infiltration into public realms. The last chapter discusses the necessity of prosecutory measures as the first step toward 'Fair Society.'

In Network Environment, Kerberos certification mechanism to require Kerberos server in other area unconditionally belief. Also, Kerberos server in cooperation area must be share server of other area and secret key. To solve these two problems, this paper proposed safe security mechanism of doing to ably IETF CAT's PKINIT/PKCROSS a1gorithm with Public Key Infrastructure and use Directory System and service between realms do trust and prove each Kerberos trust center base. Also, Although Kerberos server of each area must be foreknowing each server's secret key and public key, Obtain through Trust center and acquire each area's public key and common symmetric key, Application server excluded process that must register key in Key Distribution Center.

Kerberos is designed to provide strong authentication between client and application servers which are working in distributed network environment by using symmetric-key cryptography, and supposed to trust other systems of the realm. In this paper, we design an efficient and strong authentication mechanism by introducing the public/private-key to Kerberos. In the mechanism to make a system more secure, the value of the session key is changed everytime using MAC(message authentication code) algorithm with the long-term key for user-authentication and a random number exchanged through the public key. Also, we employ a mutual authentication method, which is used on challenge-response mechanism based on digital signatures, to improve trust between realms, and present a way of reducing the number of keys by simplifying authentication steps.
