In the light of the strategic utilization of the national R & D projects, this paper is to induce the spin-off strategies to improve the national R & D effectiveness through analyzing the spin-off characteristics of nuclear technologies, the spin-off status of the advanced countries and the case study of Korean nuclear spin-offs. Spin-off process is viewed as a three-stage operation, such as preparation stage, implementation stage and maintenance stage. In order to find the correlation between the influencing factors and spin-off effectiveness, the Spearman's correlation coefficient was employed as a specific statistical technique. By integrating this correlation, spin-off process and spin-off strategies, this paper presents an efficient framework to improve the spin-off effectiveness.

We are developing a web-based movie recommender system that catches and reasons with user profiles and ratings to recommend movies. In the paper, we outline the current status of our implementation with particular emphasis on the mechanisms used to provide effective recommendations. Social recommender systems collect ratings of items from many individuals and use nearest-neighbor techniques to make recommendations to a user. However, these methods only depend on the ratings and ignore other useful information. Our primary concern is to provide an approach that can recommend the movies based on not only the user ratings but also the significant amount of other information that is available about the nature of each items - such as cast list or movie genre. We experimentally evaluate our approach and compare them to conventional social filtering, which suggests merits to our approach.

It is a tendency for enterprises in the domestic construction field to harness the system scaffolding with an aim to securing safety, despite slight increase in terms of the construction cost. Nevertheless, given that putting the system into service in reality is not accurately surveyed by far and that safety standards and methods for safe work therewith are not yet established, hazardous factors involving the system scaffolding remain latent leaving unrecognized. In this regard, the current study attempts to understand the status of implementation and use of the system scaffolding in the local construction sites as for the year 2009 and the year 2013 through questionnaire surveying and in-depth interviewing, while further proposing, based on the result thereof, ways for activating introduction of the system scaffolding in an effective and systematic manner.

Depending on the development of technology, android-based smartphones has brought about various changes in our lives. In this paper, based on smartphones, it was implemented that the biometric information of human pulse wave and oxygen saturation by measuring device can be monitor the status of the patient on bluetooth-based u-health care system. Through the implementation of this paper, it has confirmed that it's can be monitoring smartphone adding a bluetooth module on the medical equipment of PC based monitor system.

One of the most important prerequisites for a successful software process is the collaboration and software requirements negotiation of all stakeholders in the software development process. Remote users using computer networks can negotiate software requirements by computer supported system, and can share their informations. The goal of software requirements negotiation system is an integration of all win conditions and an agreement after resolution of conflicts. The existing systems need an exclusive system and must be dependent on specific platform and network. Users must have the knowledge of all stakeholder's status and use homogeneous collaborating applications. This paper presents the Web-based software requirements negotiation system for the purpose of resolution of the existing systems' problems. The Web-based software requirements negotiation system can be driven by WinWin Spiral model, and it is based on hybrid execution method. The proposed system is validated and tested on heterogeneous environments.

In maned ship, crews may have risks as they manage damage control system in IPMS in damage situations such as fire in a ship. So the application of unmaned autonomous systms can reduce the number of boarding crews and attribute to safe marine transportation. The paper suggests an intelligent system of the fire fighting control using fuzzy logic in Integrated Platform Management System which can take measures against fire situation of a ship excluding unnecessary warnings with undamaged situations. The system here detected the fire more accurately and adopted more appropriate measures according to ship status compared with conventional systems. Of all, a reduction of false detection of fires was noted.

Korea is now classified as an area of intermediate endemicity for hepatitis B virus (HBV), due to the implementation of universal HBV vaccination and national preventive programs for HBV infection. A national program of HBV vaccination was launched in Korea in 1988 for school-going children and was listed on a vaccination guideline in 1991. In 1995, universal vaccination for newborn infants was started for the prevention of perinatal HBV transmission. The prevalence of HBsAg among Korean middle school students has shown marked decreased from 3.2% in the late 1990s to 0.44% in 2007. HBsAg positivity in preschool children was 0.9% in 1995, decreased to 0.2% in 2007 by national prevention program of hepatitis B vertical transmission, launched in 2002. Vaccine failure rate of HBV immunoprophylaxis is 4.2% by this program. The infected children should be monitored per 6-12 months interval. Lamivudine and interferon are approved therapies for children with chronic hepatitis B in immune-clearance phase in Korea.

This study, in particular, studied the consortium-participating companies on their plans of Quality Management as to how they carry them out in order to advance to the first-class business enterprises. These companies' present status and activities under implementation identified and interpreted by this study, therefore, are insufficient to be generalized into knowledge applicable to most of the companies in Gangwon-do. For more precise and detailed results, it is suggested to make further studies that cover not only those consortium companies but also non-consortium manufacturing companies if Gangwon-do.

This paper is focused on implementing a real-time data acquisition system that checks power facility status by applying network based technology to Urban Transit substation power facilities and the results of its on-field tests. This system is composed of a sensor part, a measurement part, a transceiver part, a host computer, and a power source part. The system is designed to collect, save, analyze, and display the online state power facility AI (Analog Input). This system measures voltage and current from positive feeders and negative feeders where it is possible to check abnormalities of the substation‘s main power facilities. By monitoring abnormal data of the Urban Transit power facilities real-time and analyzing stored data, establishing procedures of optimized maintenance is possible.

A difficult problem in operating Flexible Manufacturing Systems (FMS) is to control the system in real-time by coordinating heterogeneous machines and integrating distributed information. The objective of the paper is to present the models and methodologies useful to resolve the difficult problem. The detailed objectives can be described in three folds. First, a hierarchical Colored and Timed Petri-Net (CTPN) is designed to control an FMS in real-time. The concerned FMS consists of a loading station, several machining cells, a material handling system, and an unloading station. Timed-transitions are used to represent the timed-events such as AGV movements between stations and cells, part machining activities in the cells. Signal places are also used to represent communication status between the host and the cell controllers. To resolve the event conflicts and scheduling problems, dispatching rules are introduced and applied. Second, an implementation methodology used to monitor and diagnose the errors occurring on the machines during system operation is proposed. Third, a Petri-Net simulator is developed to experiment with the designed control logic.
