  • The AIS(Automatic Identification System) has been widely used for ship safety at sea over the last 10 years. The AIS traffic load at VDL(VHF Data Link) has been continuously increased. As the traffic load at VDL increases, the quality of AIS service may be deteriorated. In the previous research, the AIS traffic has been analyzed in the major ports of Korea, and its problem due to traffic overload has been suggested. However, no solutions has been given so far. In this paper, the method of autimatically controlling the VDL traffic at AIS base station is represented.

  • This article attempts to explore how the women retirees under study were able to continue work until retirement. This study used life histories, especially focusing on daily working lives, and uncovered a number of key issues through in-depth interviews. The main results are as follows: Firstly, the women retirees examined here had been raised as highly educated people, and their strong educational background was a base component for them to have relatively secure careers. Their parents had also supported practically the women retirees during their working lives. In addition, the women retirees had to can out the roles of 'provider' for their original families, procreation families or in-law families, even though they were not given the recognized roles of provider. Secondly, the women retirees had a private infra system to support them with housework and child care. In addition, because they were financially able to employ housemaids, the women retirees did not experience conflicts with their husbands, who took on a neo-traditional sex role. Finally, thanks to relatively good working conditions such as having vacations and being able to come to and leave the office on time, the women retirees were able to continue work until retirement no mean feat in a society which openly practiced gender discrimination.

  • This study attempted to develop integrated family policy. For this purpose, a delphi survey was conducted twice among 15 professionals regarding the general contents of family policy, the goals and outcomes of president Roh's administration, the direction and plan of action for future family policy. The results of this study are as follows: Firstly, the main results of president Roh's administration were the creation of the Ministry of Women and Families, and the Healthy Families Law. Nevertheless, that government had no long-term vision or action programs. Secondly, there are two aspects of family policy which one is family members based and the other is family life cycle based. Accordingly the subjects of this study insist that family policy has to cover people's whole life, all families regardless of family structure, and has to integrate the plans and programs which have been served to individuals, for example, women, child, youth, and elderly. Thirdly, the orientations of future family policy are to be toward happiness, health, equality, coexistence, harmony, growth, generosity, diversity, self-control, and a sustainable society. So the concept of the integrated family policy has to cover all aspects of the family and the diversity of family life. Therefore, the service delivery system for family policy has to converge into the Healthy Family Center.

  • The ship's heading information of hybrid GPS/EM compass were applied to the AIS of fishing vessel and examined the possibility of accuracy improvement. It is observed 453 each in AIS receiver of land among 3,982 each in AIS Rx/Tx transponder of the test ship at sea, and transmission interval according to the speed of ship is determined the 11.4% good transmitting data of the all information. In results, maximum compass error for the ship's heading of an EM compass was $19.1^{\circ}$. The variance of ship's heading owing to the speed of ship is surveyed. The COG (Course Over Ground) was changed extremely in $180^{\circ}W-179^{\circ}E$ range under 4.9knots, and in $24^{\circ}W-23^{\circ}E$ range over 4.9knots. Finally, using the ship's heading of EM compass and the COG from GPS for the autopilot system of a small fishing boat and the ship's heading information of AIS results in danger on the own ship's navigation safety and leads to make confusion both the others and VTS (Vessel Traffic Service) center. Therefore, the hybrid GPS/EM compass is identified as the best system for a small fishing boat and is allowed to offer continuously a ship's heading information with high accuracy and stability.

  • The voice recognition technology is to recognize the voice of an user and execute the command. Recently, the voice recognition is evolving to the artificial intelligence voice recognition by adding the scheme of the natural language processing. The AI voice recognition is exploited to control the IoT devices or provide the information, such as the news or the wether. The University Information which is one of fields serviced by the information provider is mainly presented on the web. However, since too much information are presented on the web, it is difficult for an user to find efficiently the specific information which the user want to know. In this paper, we design and implement the university guidance system to recognize the user voice searching the information and provide the result using the voice. To do this, we classify the university data and design the lambda function to provide the data.

  • As for the digital content, a reproduction is easy and manuscript is identical with original copy. Because of these characteristics, there are difficulties on prevention of an illegal reproduction and an illegal currency. In recent days various digital content service systems based on a web are commercialized. An appropriate copyright protection technology is required so that these systems develop as a profit model. Generally we use encrypted digital content transmission method for the copyright protection on a web base system. At the time of this, it is increased sire of encrypted digital content. As for this, it be increased time required on an execution process. Therefore, a design of the system that considered a execution time and a security is required. In this study, we designed the digital content transmission system that considered execution time and a security through a partial encryption based on a digital content copyright management technique. Also we evaluated performance of a proposed system through analysis.

  • In a new technological environment such as big data and AI, LOD will link record information resources with various data from both inside and outside. At the heart of this connection is the interlinking technology, and interlinked LOD will realize the opening of record information as the highest level of open data. Given the ever-increasing amount of records, automation through interlinking algorithms is essential in building LODs. Therefore, this paper analyzed the structure of record information interlinking with the external data and characteristics of the record information to be considered when interconnecting. After collecting samples from the CAMS data of the National Archives, we constructed a record information's LOD. After that, we conducted a test bed that automatically interlinks the personal information of the record metadata with DBPedia. This confirms the automatic interlinking process and the performance and accuracy of the automation technology. Through the implications of the testbed, we have identified the considerations of the record information resources of the LOD interlinking process.

  • Recently, as artificial intelligence technology becomes popular, demand for wireless traffic is rapidly increasing. In order to provide services in response to the increase in demand for wireless traffic, telecommunication companies are generalizing the installation of public APs. In order to provide convenience of using wireless APs between communication companies, it is necessary to share the use of APs in public places to efficiently use wireless resources in a public place, to pre-authenticate between wireless APs in a mobile communication service, So as to increase the convenience of the user. In this paper, we propose to share APs in public places through handoff between APs and pre-authentication between carriers in mobile communication services. The simulation results show that the handoff latency is improved by 35.1% and the bandwidth used by the AP selected by the pre-authentication method can utilize more bandwidth than the method of automatically selecting the AP.

  • The present study was undertaken to evaluate the effect of Rhodiola sachalinensis root ethanol extract (RS), on the body weight, organ weight, plasma glucose and plasma lipid in diabetic rats caused by streptozotocin (STZ). The body weight decreased more slowly in the RS group than in the diabetic, and the food intake increased significantly in all diabetic groups. The food efficiency was very low in all diabetic groups, but increased significantly in the RS groups than diabetic control (p<0.05). In comparing the weight of organ, the weight of liver and kidney were increased in all diabetic groups than in the control, and decreased slightly in RS groups. The weight of heart and spleen were not different among all test groups. The glucose in serum was decreased significantly in the RS groups fed the RS for 4 weeks, compared to the diabetic control (p<0.05). Total cholesterol, triglyceride and atherogenic index (AI) in serum were significantly higher in diabetic control, compared to the normal (p<0.05), and decreased $16.7\%,\;18.3\%\;and\;45.0\%$, respectively, in the RS fed $300\;\cal{mg/kg}$ of RS. HDL-cholesterol was increased slightly more in the $RS-300\;\cal{mg/kg}$, compared to diabetic control. These findings suggest that RS treatment has protective effect in diabetes.
