인터넷과 정보통신기술을 배경으로 한 전자상거래 확산은 유례가 없을 정도의 빠른속도로 이루어지고 있다. 특히 XML이 W3C의 공식 표준으로 공식화 된 이후, XML의 확장성, 호환성, 정보의 구조화와 같은 장점으로 XML은 전자상거래 프레임워크의 새로운 페러다임이 되었다. 이러한 XML 전자상거래 프레임워크로는 xCBL을 필두로, eCo 프레임워크, cXML, BizTalk, ebXML등 많은 국제 표준이 있다. 그러나 이러한 다양한 프래임워크들은 메시지규칙에 대한 정의와 전송 프로토콜 정의, 비즈니스 프로세스의 수평적 통합만을 고려하고 있다. 즉 비즈니스 객체간의 상호작용을 위한 일반된 표준을 제공해주지 못하고 새로운 비즈니스 상대자가 등장할 경우 새로운 규칙을 설정해야 하는 부담을 해결하지 못한다.본 논문에서는 ISO/IEC 11179에 기반을 둔 MDR(Metadata Registry)를 이용한 MDR 기반하이브리드(Hybrid) 프레임워크 (Framework)를 제안한다 본 하이브리드 구조의 프레임워크를 통하여 기존의 수평적 관계의 프레임워크가 갖고 있는 비즈니스 프로세스 및 메시지 규칙의 문제점들을 해결할 수 있다.

Cyber security plays an important role in the field of IT industry and other industry too. Whenever we talk about cyber security, the word cybercrime pops out. Cybercrime is the biggest issues we are facing right now. Every 39 seconds an attacker is hacking something. Since 2008 to 2019 there are more than 8800 data breach cases is being found or filed. Even as we are aware of cybercrime and its stats, only 5% organization are fully secured and other 95% are not fully secured. According to survey 56% organization have weak controls. Basically they are not secured. Apart from taking measures cyber security are facing huge challenges or disturbs to many. This paper mainly focuses on dare to cyber security and also center of attraction is cyber security expertise, morals with changing in technology with time. [1]

Given the proliferation of social network services, it has become important to understand its user's continued use behavior. As users' privacy concerns in SNS have been identified as a critical barrier against forming this continued intention, many studies have focused on inducing continued intention by mitigating privacy concerns. However, this paper suggests to approach users' continued intention not only from the perspective of mitigating privacy concerns but also from the perspective of increasing potential benefits. Under the theoretical framework of privacy calculus model, we conducted cross sectional survey on 150 Facebook and 150 KakaoTalk users. The result suggests that trust mediates the relationships between privacy concerns and continued intention and between network externality and continued intention, and the influence of support for network formation on continued intention. The effect of network externality on continued intention, however, is not significant among Facebook users while it is significant among KakaoTalk users.

Even though it is generally recognized that entrepreneurship is complex socio-economic phenomena and entrepreneurial opportunities can be created from economic, social, technological, political and legal forces, entrepreneurship has been discussed in very narrow economic terms and focusing on narrow economic relationships such as consumers, suppliers, owners and employee. However, recently, a lot of researchers talk about social entrepreneurship. How can we explain social entrepreneurs? In our paper, employing stakeholder theory, we try to offer more realistic model to understand entrepreneurial opportunities. We claim that entrepreneurial exploitations can be successful only when entrepreneurs can identify ex post stakeholder inefficiencies. Thus, our efforts focus on the question of where, when, and how stakeholder inefficiencies occur?

In this study, we developed a chatbot (Dialogue agent) using small Q & A data and evaluated its performance. The chatbot developed in this study was developed in the form of an FAQ chatbot that responds promptly to customer inquiries. The development of chatbot was conducted in three stages : 1. Analysis and planning, 2. Content creation, 3. API and messenger interworking. During the analysis and planning phase, we gathered and analyzed the question data of the customers and extracted the topics and details of the customers' questions. In the content creation stage, we created scenarios for each topic and sub-items, and then filled out specific answers in consultation with business owners. API and messenger interworking is KakaoTalk. The performance of the chatbot was measured by the quantitative indicators such as the accuracy that the chatbot grasped the inquiry of the customer and correctly answered, and then the questionnaire survey was conducted on the chatbot users. As a result of the survey, it was found that the chatbot not only provided useful information to the users but positively influenced the image of the pension. This study shows that it is possible to develop chatbots by using easily obtainable data and commercial API regardless of the size of business. It also implies that we have verified the validity of the development process by verifying the performance of developed chatbots as well as an explicit process of developing FAQ chatbots.

It was in the fifteenth century in Italy that men began to talk of a rebirth in the arts and literature. Today we consider the period to belong to the Renaissance. We noticed the splendour of costume and the important role it played, in the life of Italian society in that period. From elsewhere in Europe and also from the East, dyestuffs came to Italy overland or in shiploads. Red and blue, notably kermes and madder on the one hand, and indigo and woad on the other were fundamental textile dyes in Italy. Saffron was used for yellows, oak galls for blacks. Renaissance Italian costumes' main color symbolized various meaning. Red symbolized high rank, affection, lady, redemption and various cardinal virtueses. Yellow was evaded color which was symbolized the lower class, betrayal, and gold. Green symbolized penniless, youthfulness, hope and love. Blue symbolized humbleness, sincerity, knowledge and the Madonna. Purple symbolized nobility, vice and various meanings. Black symbolized death, grief, beauty and elegance. These color symbols in the Renaissance Italian costumes were very similar to that of modern color symbols.

Instead of using three charge-coupled devices (CCDs) for the corresponding color channels, most consumer's most consummer's color macmorders reconstruct color images by using only one CCD with a color filter array (CFA), which periodically samples different color signals. By this reson the resulting image cannot produce the full resolution of the input image. More sepecifically, a single-CCD color camcorder reconstructs red, greed, and blue color channels from a color filter array followed by a CCD. During the reconstruction process, color cross-talk among channels (interchannel distortion) and eriodically space-verying blur (intrachannel distortion) occur. The proposed restoration system reduces distortions due to interchannel interference, and then restores each color channel by removing the corresponding intrachannel distortion. Experimental results show that the proposedsystem provides the improved image in oth objective and subjective senses. A major advantage of the proposed system is feasible to real-time image improvement because it can be implemented by a finite impulse response (FIR) filter structure.

Korean government, port and logistics companies have given a lot of their efforts to exchange electronic documents between themselves and their partners. As the results of them, Korean EDI(Electronic Data Interchange) standards were made by Korean EDIFACT committee and the standards have been used by companies and governmental organizations in Korea. However, Korean port and logistics EDI system is based on YAN(Value Added Network) and one VAN company has monopolistic right to relay EDI documents to Korean HOMAF(Ministry of Maritime Affairs & Fisheries) and Customs Service. Therefore it leads to a lot of problems such as inconvenient software, expensive transmission fee, insufficient improvement of business process and the difficulty of connection with the in-house systems of user companies. For solving these problems, this study is aimed to progress for XML and XML-based electronic commerce framework. This paper shows a optimal XML/EDl method using XML/EDl, BizTalk Framework, ebXML Framework. Fer improving extant problems in port and logistics industry, this paper proposed XML/EDl system based on system architectural level, support technical level, business infrastructure level.
