This paper depicts a study conducted on the behavior of physical education students towards Internet usage at Kurukshetra University, Kurukshetra. Specially, the study aims to know the purposes for use of Internet resources and services, frequency of use, places and means of use, student's satisfaction level toward the Internet, and problems faced while using the Internet. A survey was carried out with a sample of 100 physical education students of Kurukshetra University and the response rate was 88%. A well-designed questionnaire was distributed to the students' sample. Amazingly, the results of the study reveal that usage of the Internet in research and education was not favored, whereas email, chatting, and sports websites were commonly used among students. The study also found that too much information on the Internet, slow access speeds, and finding relevant information were the main problems in using the Internet.

As teenagers' Internet use increases and Internet takes an important part in their everyday lives, many people become concerned with Internet addiction. In this study, I attempt to analyze the current status of teenagers' Internet addiction using an evaluation tool developed for students, and to compare elementary students' Internet addiction level with secondary students. Also I analyze factors affecting Internet addiction. For the analysis, 18 variables are selected from the areas such as demographic background, the experience of Internet use, family-related traits and social activities. A survey was conducted to 1,155 elementary students and 1,822 secondary students selected from nationwide schools. The main finding of this study is that among the elementary students 5.0% of the sample students are in the stage of serious addiction, and 19.7% in the stage of early addiction. In addition, the level of elementary students' Internet addiction is significantly higher than the level of secondary students. Also, the degree of elementary students' Internet addiction is significantly affected by some factors such as gender, surfing time, surfing purpose, satisfaction with parental relationship, parents' interference in Internet use, conversation frequency among family members, and satisfaction with school life.

As new information and communication technologies evolve, security threats are also becoming increasingly intelligent and advanced. In this paper, we analyze the time series data continuously entered through a series of periods from the network device or lightweight IoT (Internet of Things) devices by using the statistical technique and propose a system to detect abnormal behaviors of the device or abnormality based on the analysis results. The proposed system performs the first level abnormal detection by using previously entered data set, thereafter performs the second level anomaly detection according to the trust bound configured by using stored time series data based on time attribute or group attribute. Multi-level analysis is able to improve reliability and to reduce false positives as well through a variety of decision data set.

In this paper, we propose a novel traffic measurement based detection of network attack symptoms on high speed Internet backbone links. In order to do so, we characterize the traffic patterns from the normal and the network attacks appeared on Internet backbone links, and we derive two efficient measures for representing the network attack symptoms at aggregate traffic level. The two measures are the power spectrum and the ratio of packet counts to traffic volume of the aggregate traffic. And, we propose a new methodology to detect networks attack symptoms by measuring those traffic measures. Experimental results show that the proposed scheme can detect the network attack symptoms very exactly and quickly. Unlike existing methods based on Individual packets or flows, since the proposed method is operated on the aggregate traffic level. the computational complexity can be significantly reduced and applicable to high speed Internet backbone links.

As Internet usage has increased, the risk of adolescents being exposed to adult content and harmful information on the Internet has also risen. To help prevent adolescents accessing this content, a novel detection method for adult images is proposed. The proposed method involves three steps. First, the Image Of Interest (IOI) is extracted from the image background. Second, the IOI is distinguished from the segmented image using a novel weighting mask, and it is determined to be acceptable or unacceptable. Finally, the features (color and texture) of the IOI or original image are compared to a critical value; if they exceed that value then the image is deemed to be an adult image. A Receiver Operating Characteristic (ROC) curve analysis was performed to define this optimal critical value. And, the textural features are identified using a gray level co-occurrence matrix. The proposed method increased the precision level of detection by applying a novel weighting mask and a receiver operating characteristic curve. To demonstrate the effectiveness of the proposed method, 2850 adult and non-adult images were used for experimentation.

This research aims to investigate the casual effects of not only the level of ethic awareness in general among internet users but also the level of internet skills on inadequate behaviors in cuber spaces. This research also try to develop the framework for the cyber ethic educational program in order to establishing adequate attitudes in cuber spaces. For accomplishing the purposes of this research, the data, 522, had been collected from both on-line and off-line. The major statistical methods for data analysis were frequency, factor analysis, multiple regression, and path analysis. The results of this casual effect analysis were as follows: 1. There were positive direct causal effects of sex, occupation, place for internet use, and internet skills on inadequate behaviors in cuber spaces. On the other hand, the negative casual effect of the awareness of legal ethics on inadequate behaviors in cuber spaces. 2. Such variables as sex, age, internet-related and the awareness of ethics in general had indirect causal effects on the inadequate behaviors in cuber spaces through the variable which is the awareness of cyber ethics. The implications of this findings were discussed.

In this paper, based on the real estate registration model in the Chinese internet environment, we propose a model for the joint business of banking collateral registration. This is to increase the efficiency and service level of the real estate mortgage registration process. And it can solve the problems that in the process of registering a mortgage loan, difficulty of data sharing between the real estate registration agency and the bank, and ordinary users and bank clerks duplicate unnecessary work. In addition, it realizes joint processing and data sharing of real estate registration work with real estate registration agencies and banks, increases the efficiency and level of government affairs services, and offers an optimized solution to realize a one-stop service for real estate security registration. The results of this study are expected to provide theoretical support for the application and innovation of the Internet environment real estate registration model.
