P2P systems have gained a lot of research interests and popularity over the years and have the capability to unleash and distribute awesome amounts of computing power, storage and bandwidths currently languishing - often underutilized - within corporate enterprises and every Internet connected home in the world. Since there is no central control over resources or devices and no before hand information about the resources or devices, device discovery remains a substantial problem in P2P environment. In this paper, we cover some of the current solutions to this problem and then propose our feed forward neural network (FFNN) based solution for device discovery in mobile P2P environment. We implements feed forward neural network (FFNN) trained with back propagation (BP) algorithm for device discovery and show, how large computation task can be distributed among such devices using agent technology. It also shows the possibility to use our architecture in home networking where devices have less storage capacity.

본 연구는 언어 네트워크 분석 기법을 이용하여 현대자동차의 문화마케팅 유형과 변화를 분석하고 국내 문화마케팅의 발전 양상을 제시하고자 하였다. 기존 연구는 기업 문화마케팅의 개념 규정과 유형화, 문화마케팅의 영향 및 성과 등을 살펴보았지만, 시간의 흐름에 따른 기업 문화마케팅의 변화는 주목하지 않았다. 이에, 본고는 다양한 형태의 문화마케팅을 시행해온 현대자동차를 대상으로, 현대자동차의 문화마케팅이 보도된 2001년부터 2018년까지를 시간적 범주로 설정하고 국내 일간지 기사 2,315건을 분석하였다. 18년의 시간을 4개 시기로 분류하고, 시기마다 빈출단어를 추출하여 한국어 언어 분석 프로그램 텍스톰(Textom)과 언어 네트워크 분석 프로그램 유씨넷(UCINET)으로 분석하였다. 연구 결과, 현대자동차는 문화마케팅을 판매와 영업 성과를 향상하기 위한 수단으로 활용함과 동시에 기업과 브랜드 정체성을 차별화하기 위한 전략으로 발전시키고 있었다. 2000년대 초반에는 '고객', '위대한 회화의 시대: 렘브란트와 17세기 네덜란드 회화전', '공연'이 빈도수가 높은 단어로 추출되었다. 현대자동차가 공연 중심의 문화 행사를 고객 대상으로 개최하여, 특정 소비자 그룹에 혜택을 제공하는 방식으로 시작하였다. 2000년대 후반에 상위 노출된 단어는 '예술의 전당', '서울시립교향악단'으로, 인지도 높은 문화예술기관의 주요 문화 행사에 후원하였다. 2010년대 초반에는 기존고객 중심에서 잠재 고객으로 대상을 넓히고, 문화마케팅을 아우르는 브랜드와 공간('브릴리언트'와 '현대아트홀')을 선보였다. 2010년대 중후반에는 노출 빈도가 높은 '브랜드'와 '글로벌'에서 보여주듯, 문화마케팅의 초점이 고객에서 브랜드 구축으로, 국내에서 글로벌로 확장되고 있다.

Customer satisfaction becomes one of the important managerial concerns associated with corporate competency in current competitive environment for Internet communication service companies. Hence, it is demanding to improve a company's customer satisfaction through the total quality management perspective. In practice, engineers as well as the management hope to find major quality characteristics with Internet communication network that is closely related to customer satisfaction, consequently aiming to the raise of their company's customer satisfaction. This paper presents an empirical relationship analysis between network quality characteristics and customer satisfaction on Internet communication. Methodologically, the relationship analysis framework is based on the regression variable selection procedures. In this framework, it is implemented that; 1) iterative model building; and 2) consistent criteria application to statistical tests for selecting significant variables. A case study shows that; 1) the customer satisfaction on the network connection seems to be more closely related to the network quality characteristics compared with the customer satisfaction on the network speed; and 2) the download disconnection rate has relatively evident relationship with the customer satisfaction on the network connection.

세계경제는 정보${\cdot}$통신 기술의 발달, 기업의 재조직화, 그리고 해외투자의 신장 등에 의해 매우 급속하게 변화하고 있다. 오늘날 세계화된 경제체제속에서 가속되는 상호의존과 금융자유화는 다국적 기업을 빠르게 팽창하게 하고 세계 경제의 형성에 가장 중요한 결정인자로 작용하게 하고 있다. 기업의 중심업무기능, 즉 명령, 통제, 조정, 전략적 의사결정등은 계속 그 범위와 양이 증가하고 있으며 대규모 4차 산업공간에 집중되고 있다. 반면에 기업체계의 조직적 유연성은 분권화된 내외적 기업 네트웍 형성을 통해 점차로 증대되고 있다. 본 연구는 네트웍국제화이론에 바탕을 두고 4차산업활동의 대표적인 사례인 다국적기업의 본사-해외지사의 입지와 연계의 변화를 각 경제부문별로 고찰해 보았다. 연구 기간동안 4차산업활동의 공간은 점차로 분산되고 있으며 그 연계도 수직적이고 하향적인 계층적 형태에서 어느정도 수평적인 네트웍형태로 변화하고 있다. 이러한 분산과 다양화는 중${\cdot}$소규모의 도시(4차산업활동의 공간)와 서비스산업을 중심으로 활발하게 진행되고 있다. 앞으로 세계체제도 다원화되고 대도시의 영향력이 포화점에 이르면 다국적기업의 입지와 네트웍도 더욱 분산되리가 예상된다.

무선 네트워크를 이용한 사용자의 업무 편의성 및 효율성이라는 순기능은 보안 위협이 발생하면 심각한 네트워크 자원 가용성의 침해와 더불어 중요한 기업 정보의 유출로 이어질 수 있다. 특히 무선 AP(Access Point)를 통해 보안 취약점을 악용한 다양한 보안 공격과 이로 이한 피해가 늘어나고 있다. 이러한 다양한 공격에 대항하고 내부망을 보호하기 위해 공공기관 및 기업에서 WIPS(Wireless Intrusion Prevention System)를 도입하는 사례가 늘어나고 있다. 하지만, WIPS 솔루션 도입시 고려해야 할 높은 비용은 개인 또는 소규모 회사에서의 WIPS 솔루션 도입을 방해하는 주요 이슈이다. 본 논문에서는 WIPS 솔루션 도입에 따른 비용 문제를 절감하고 다양한 무선랜 보안 위협들을 차단하기 위한 라즈베리 파이를 이용한 WIPS 센서 구현 방안을 제안한다. 이를 통해 비교적 낮은 비용으로 기업 정보를 보호하고 서비스 연속성을 제공할 수 있을 것으로 기대한다.

This research was conducted on 176 GVCs-related research papers listed in the Index of Korean Academic Writers. The analysis methodology used the keyword network analysis methodology of big data analysis. For the comprehensive analysis of research trends, the research trends through word frequency (TF), important topic (TF-IDF), and topical modeling were analyzed in 176 papers. In addition, the research period of GVCs was divided into the early stages of the first study (2003-2014), the second phase of the study (2015-2017), and the third phase of the study (2018-2020). According to the comprehensive analysis, the GVCs research was conducted with the keyword 'value added' as the center, focusing on the keywords of export (trade), Korea, business, influence, and production. Major research topics were 'supporting corporate cooperation and capacity building' and 'comparative advantage with added value of overseas direct investment'. According to the analysis of major period-specific research trends, GVCs were studied in the early stages of the first phase of the study with global value chain trends and corporate production strategies. In the second research propulsion period, research was done in terms of trade value added. In the recent third phase of the study, small and medium-sized enterprises actively participated in the global value chain and actively researched ways to support the government. Through this study, the importance of the global value chain has been confirmed quantitatively and qualitatively, and it is recognized as an important factor to be considered in the strategy of enhancing industrial competitiveness and entering overseas markets. In particular, small and medium-sized companies' participation in the global value chain and support measures are being presented as important research topics in the future.

We categorize partnership types between network operators and a global video streaming or over-the-top service provider, Netflix from 2011 to the first quarter 2018. The options are based on the integration of over-the-top (OTT), Netflix with pay TV and telecommunication operators in the form of carrier billing, access to over-the-top (OTT) via devices or the development of their tariff plans. Options of the Type 3, 'cooperation' or the Type 4, 'agreement' entails a kind of the technical involvement between two partners and commercial agreement. The types of partnership are evolving from one to others. Some partnerships have characteristics of more than one type. The majority of technical or service integration cooperation of Type 3 entail bundling and marketing promotion of Type 2 and Type 1. Similarly, the 'agreement' of Type 4, co-branded or white-label service initiative entail tariff or device user interface (UI) integration of the 'cooperation' of Type 3 and joint marketing initiatives of Type 1.

Firms seldom survive and prosper solely through their individual efforts. Each firm's performance depends upon the activities and performance of others and hence upon the nature and quality of the direct and indirect relationships a firm develops with its counterparts. Textile companies have tried to improve their organizational competitiveness in order to survive in the digital age global market. The challenge in textile supply chain management is the development of collaboration network which accommodates diverse concerns of various participants while explicitly recognizing interdependencies and promoting effective relationship management. Major contents of the study are as follows. First, ideal collaboration network model from the supply chain of the textile industry is suggested. Second, utilizing the collaboration model, A framework for textile e-marketplaces supply chians is designed to improve customer services and delivery time, to promote information sharing, and shorten product life cycle time. The framework suggested is expected to promote corporate innovation and information sharing, generate infrastructure which provides appropriate communication and operations capabilities for the textile companies.
