This paper addresses construction of a new network of invention education through the internet and creates a plan to apply it to practical invention education. We examined the status of invention education in Korea, the U.S., and Japan to consider problems of practical invention education and to draw a particular direction for the future invention education. Various papers, books, and documents related invention education were reviewed to make teaching and teaming strategies of invention education. Based on the analyses, criteria of teaching and loaming were identified as how to challenge teachers, students, parents, and administrators to successful implement invention education practices. Using the criteria of teaching and teaming, we designed a framework for a website and constructed a practical website concerned with invention education, including constructive components in the framework. This will require an experimental application during which teachers and researchers can do revisions and add supplementary information. This network system will provide practical information in regard to invention education and created a communications system for in charge of invention education.

This paper explored that medial consumers' trusts in both hospitals and doctors are developed by and during investigating hospital websites and that these trusts directly build the consumers' purchase intentions of the hospitals' offline medical services. 208 questionnaires based on the websites of two virtual hospitals, captured on survey brochures, were collected and analyzed. This research indicated information quality of hospital websites affected more on developing consumers' trusts than service quality.

Consumer dissatisfaction and complaints make it difficult for online shopping mall to maintain existing customers and attract new customers, which may result in a direct profit loss. The primary purpose of this study is to investigate the relationship between customer dissatisfaction in terms of product-complaints and website complaints and complaint behaviors in terms of individual, public, and 3rd party complaint behaviors. Th results indicate that product-dissatisfaction is significantly related to the public and 3rd party complaint behaviors, but not the individual complaint behavior. Website dissatisfaction was not found to be significantly related to any complaint behavior. The moderate effect of sex and individual attitude on the relationship between customer dissatisfaction and complaint behaviors was also not considerable.

The purpose of this research is to develop a webcasting site evaluation model, to estimate the relative importance of factors affecting the performance of webcasting sites, and to derive the CSFs of the sites. Evaluation model consists of 6 first-level evaluation factors and 23 second-level evaluation factors. This study compares the evaluation scores of website with those of the customer satisfaction. We inspect seven hypotheses. Hypothesis)(H1) tests correlation of the evaluation scores of website and those of the customer satisfaction. Hypothesis2(H2)$\sim$Hypothesis7(H7) tests if 6 first-level factors(planning, program & form, design, technology, interface, content) have an impact on customer satisfaction. In order to test the hypotheses, correlation analysis and regression analysis are performed. As a result of empirical tests, all Hypotheses$(H1){\sim}H7)$ are accepted and its implications are discussed.

As the container market is expected to continue to increase, the volume of containers will increase, and the volume of empty containers will be proportional to this. Imbalances between imports and exports in each country have emerged, and the issue of collection and storage of empty containers is becoming more and more important, and it is necessary to appropriately deal with container demand for container presents. Therefore, in this paper, we are trying to develop a website that provides various empty container information and provides empty container leasing services based on this information. Through the development of these empty container websites, we would like to make empty container leasing and operations more efficient, improve empty container-related services and reduce costs.

Malicious code distribution on the Internet is one of the most critical Internet-based threats and distribution technology has evolved to bypass detection systems. As a new defense against the detection bypass technology of malicious attackers, this study proposes the automated tracing of malicious websites in a malware distribution network (MDN). The proposed technology extracts automated links and classifies websites into malicious and normal websites based on link structure. Even if attackers use a new distribution technology, website classification is possible as long as the connections are established through automated links. The use of a real web-browser and proxy server enables an adequate response to attackers' perception of analysis environments and evasion technology and prevents analysis environments from being infected by malicious code. The validity and accuracy of the proposed method for classification are verified using 20,000 links, 10,000 each from normal and malicious websites.

본 연구는 온라인 관광정보의 내용 및 텍스트 네트워크 분석을 주요한 연구목적으로 한다. 이를 위해 본 연구는 한국의 대표 관광지 중 하나인 제주도를 연구대상지로 선정하였으며, 제주 DMO의 공식 관광정보 웹사이트와 중국 소셜네트워크 중 하나인 Sina Weibo 개인 블로그의 제주관련 관광정보를 수집하였다. 분석은 중국어 빅데이터 분석 프로그램 중 하나인 ROST Content Mining System을 이용하여 관광정보의 내용분석과 텍스트 네트워크 분석을 진행하였다. 내용분석 결과 제주 공식 웹사이트의 경우 자연, 지리, 시설자원과 관련된 명사, 자원의 존재가치와 관련된 동사, 자원의 아름다움과 깨끗함, 편리함 등과 연계된 형용사들이 주로 나타났다. 반면, 개인 블로그의 경우 한류, 음식, 지역특산물, 연계관광지, 쇼핑과 관련된 명사, 제주에서의 활동과 느낌에 대한 동사, 제주관련 경험이나 느낌과 연계된 형용사들이 주로 나타나고 있었다. 텍스트 네트워크 분석결과, 공식 웹사이트의 경우 자연성 및 지리적 속성 위주의 다양한 중심성이 확인되었으나, 개인 블로그의 경우 중심성과 연계성이 매우 미약하였다. 이상의 연구결과는 관광목적지의 수요기반 마케팅 전략 수립에 다양하게 활용될 수 있을 것이다.

The communications market can be characterized for its overflow of users, oligopoly business structure, 24/7 open service, incomplete sales, and operation of core platform function. These characteristics have lead users to continuously make complaints and suffer inconveniences, and thus the concept of user protection has come to receive attention. This study aims to propose solutions through communication channeling between businesses and users, based on website construction from the viewpoint of user protection. In particular, a research model was developed to display how the information symmetry of websites can be influential on the satisfaction, reliability, and continuous intention for using communication services. Total of 14 hypotheses were set to measure a significant degree of variables corelation and eight hypotheses were accepted finally. The analysis results showed that information symmetry of telecommunication service websites had a positive effect on intention for continuous usage. Through the research results, it is expected that communication service businesses will be able to consider important factors when constructing websites. Furthermore, the results are expected to be utilized as for ensuring users' continued usage of their communication services.

The phishing attack is a malicious emerging threat on the internet where the hackers try to access the user credentials such as login information or Internet banking details through pirated websites. Using that information, they get into the original website and try to modify or steal the information. The problem with traditional defense systems like firewalls is that they can only stop certain types of attacks because they rely on a fixed set of principles to do so. As a result, the model needs a client-side defense mechanism that can learn potential attack vectors to detect and prevent not only the known but also unknown types of assault. Feature selection plays a key role in machine learning by selecting only the required features by eliminating the irrelevant ones from the real-time dataset. The proposed model uses Hyperparameter Optimized Artificial Neural Networks (H-ANN) combined with a Hybrid Firefly and Grey Wolf Optimization algorithm (H-FFGWO) to detect and block phishing websites in Internet of Things(IoT) Applications. In this paper, the H-FFGWO is used for the feature selection from phishing datasets ISCX-URL, Open Phish, UCI machine-learning repository, Mendeley website dataset and Phish tank. The results showed that the proposed model had an accuracy of 98.07%, a recall of 98.04%, a precision of 98.43%, and an F1-Score of 98.24%.
