e-Portfolio in e-Learning environment is defined as the results which either teachers or learners systematically manage global contents related to their teaching and learning, respectively. When the e-Portfolio is applied to their work including teaching and learning, it is very useful for both teachers and learners to prepare their teaching plan, and to get the opportunity of their reflection by checking out their learning output, respectively. To generate e-Portfolios, there are two ways; one for collecting it directly from teachers and learners and another for collecting it automatically as a result of learning activities through e-learning system. In this paper, for efficient management of e-Portfolio, the data is layered, classified, restructured, and provided for users' purposes and various situations. Users can construct their own e-Portfolios by adding their own logic with their purposes in different situations.

The purpose of this study was to compare the health services information need between urban area and rural area in Sooncheon City. For accomplishing this purpose, we selected 1,060 adults randomly, 744 urban residents and 314 rural residents were surveyed from 1st, December to 31st, December in 1999. Compared the difference between two areas by cross tabulation, and chi-square test were used. The results of this study are as follows: 1. There were statistically difference in sociodemographic characteristics between urban residents and rural residents, such as age, education, job, income, and insurance payment(p<0.001). 2. According to the health utilization behavior, types of health facility, satisfaction of medical cost, and satisfaction of medical results were statistically different between the two areas(p<0.001). Also utilization of the health service center, and accessibility were statistically different between urban and rural areas(p<0.001). 3. Experiencing the health service information, type of health service information, methods of information, effectiveness, and satisfaction were statistically different between the two areas(p<0.001). 4. And experience of using computer, and internet and preference of method of health service information were statistically different between urban and rural areas. Therefore, the construction of health information system should be carefully reviewed by community health service centers and they should consider the different residents information needs, and accessibility and convenience of community residents.

In dismantling factories for recycling, it is important to input actual working data to a personal computer (PC) in order to monitor the work results and related recycling rate of the inputs. This should be performed with a keyboard, a mouse, or other devices. But when a worker is working in the factory, it could be bothersome or time consuming to go to the PC. Especially, workers who works at dismantling factories have a generally low education level are scared to use a PC, which could be used as a pretext for not using the PC. In some cases, data input is performed by a worker after the day's job. In this case, it could take additional time, the worker can make more mistakes, and the data could be unreliable. In this study, we developed a man-machine interface (MMI) device using a safety helmet. A joystick-like device, pushbuttons, and a radio frequency (RF) device for wireless communication is equipped in a safety helmet. This MMI device has functions similar to a PC mouse, and it has a long communication distance. RF is used because it consumes less battery power than Bluetooth. With this MMI device, workers need not go to a PC to input data or to control the PC, and they can control the PC from a long distance. The efficiency of PCs in a factory could be increased by using the developed MMI system, and workers at the dismantling factories could have less reluctance in using the PC.

Background: Cancer has important social consequences with cancer registration as the basis of moving towards prevention. The present study aimed to estimate the completeness of registration of the ten most common cancers in patients referred to selected hospitals in Shiraz, Iran by using capture-recapture method. Materials and Methods: This cross-sectional analytical study was performed in 2014 based on the data of 2009, on a total of 4,388 registered cancer patients. After cleaning data from two sources, using capture-recapture common findings were identified. Then, the percentage of the completeness of cancer registration was estimated using Chapman and Chao methods. Finally, the effects of demographic and treatment variables on the completeness of cancer registration were investigated. Results: The results showed that the percentages of completeness of cancer registration in the selected hospitals of Shiraz were 58.6% and 58.4%, and influenced by different variables. The age group between 40-49 years old was the highest represented and for the age group under 20 years old was the lowest for cancer registration. Breast cancer had the highest registration level and after that, thyroid and lung cancers, while colorectal cancer had the lowest registration level. Conclusions: According to the results, the number of cancers registered was very few and it seems that factors like inadequate knowledge of some doctors, imprecise diagnosis about the types of cancer, incorrectly filled out medical documents, and lack of sufficient accuracy in recording data on the computer cause errors and defects in cancer registration. This suggests a necessity to educate and teach doctors and other medical workers about the methods of documenting information related to cancer and also conduct additional measures to improve the cancer registration system.

The purposes of this study were to clarify whether the health belief model could explain the women's adoption of sterilization and to find the factors which influence the adoption of sterilization. To achieve these purpose, 35 women, who visited the family planning hospital to undergo an surgical operation for sterilization, were selected and named the group of adoption. Also, 36 women, who have the same demographic characteristics as the group of adoption, and have no sterilization among the married women, were selected and named the group of non-adoption. The measuring instruments used in this study were made by the researchers on the basis of the results of the review of the related literatures. The validity of these instruments was examined by one professor majoring in nursing and two family plmanning practioners. The reliability was proven by calculation of Cronbach's α with data of the group of adoption. The data was analyzed by t-test, X²-test, and ANOVA using Computer SAS system. The results were following: 1. Health belief model could be said to explain whether women accept the sterilization or not, because the degrees of susceptibility and severity for future pregnancy and the degree of benefit or adoption of sterilization in the group of ad-option are higher than those of the group of non-adoption. 2. Influence of demographic variables on health belief variables was as follows. With advancing ages, degree of susceptibility increased in the group of adoption, and the higher the number of artificial abortion increased, the higher degree of barrier increased in the group of non-adoption. Suggestions for further studies and application to the nursing practice are as follows 1. If one wants to educate the non-adoption women, one would be better to give such information as to increase the perception of susceptibility, severity and benefit. 2. New instrument to measure the perceived barrier which includes such items as fear on well-ness of the existing children, objection of husband and postoperative complication, is needed. 3. A study to find the change of perception on health belief variables is needed, after education to increase the level of perceived susceptibility and severity on the future pregnancy, and benefit on sterilization is given.

Capstone design course in current domestic software education environment has been opened in undergraduate courses in order to improve student's practical skills. However, the capstone design course is hardly applied the software convergence trend. We opened the capstone design course in not only the students in certain department, but also the students in other departments in order to solve this problem, and then we analyzed the operating results of this capstone design course. In the analyzed result, we find that operation of the convergence capstone design course is enough satisfactory, but we find that the operation of the convergence capstone design course has the limit that the certain department operates individually the convergence capstone design project. Hence, we need that the convergence capstone design course is preferably operated as the department-integration.

Accessing unauthorized rogue APs in WiFi environments is a very dangerous behavior which may lead WiFi users to be exposed to the various cyber attacks such as sniffing, phishing, and pharming attacks. Therefore, prompt and precise detection of rogue APs and properly alarming to the corresponding users has become one of most essential requirements for the WiFi security. This paper proposes a new rogue AP detection method which is mainly using the installation information of authorized APs and the DHCP snooping information of the corresponding switches. The proposed method detects rogue APs promptly and precisely, and notify in realtime to the corresponding users. Since the proposed method is simple and does not require any special devices, it is very cost-effective comparing to the wireless intrusion prevention systems which are normally based on a number of detection sensors and servers. And it is highly precise and prompt in rogue AP detection and flexible in deployment comparing to the existing rogue AP detection methods based on the timing information, location information, and white list information.

The IVEF service is the draft standard designed for exchange of information on sea traffic between the vessel traffic systems and between the vessels. Standardization of this service is under way as a part of the next-generation navigation system, called e-Navigation. The International Association of Lighthouse Authorities (IALA) suggests, on its recommendation V-145, the IVEF service model and the protocol for provisioning of this service. But the detailed configuration of this service must be designed by the users. This study suggests, based on the basic service model and protocol provided in the recommendation V-145, the implementation of the J-VTS middleware which will facilitate exchange of information on sea traffic. The J-VTS middleware consists of various components for providing the IVEF service and for processing the IVEF message protocols. The vessel traffic systems and the vessels corresponding to upper-layer applications may use the IVEF service with the functions provided by the J-VTS middleware, and the services are designed to be accessed according to the security level of users.
