The rapidly growth of Internet is main factor that activates the Digital Contents market. However imprudent Digital Contents market could be shrunk by imprudent illegal copy and delivery. MPEG(Moving Picture Experts Group) proposed MPEG-21 Multimedia frameworks in order to solve these problem. IPMP is parts of MPEG-21 Multimedia Frameworks, when Digital Contents goes through production delivery consumption, which defines standard to keep the Digital Contents in safety. Currently IPMP defined by FCD(Final Committee Draft) level. Therefore development of system which applied to latest standard to protect and manage the Digital Contents is required. and the system consists of fourth organizations which means Metadata Production server, Tool server, License server, Consumption server. In this Paper, we made production server to parse REL(Rights Expression Language) document that has right information for content from license server, and create metadata based on MPEG-21 IPMP about the content that applied to watermark. then, after it do remuxing, transmit the protected data to consumption server.

This paper deals with the state of charge(SOC) and life cycle evaluation algorithm for lead-acid battery, which is essential factor of the electric vehicle(EV) and the stabilization of renewable energy in the smart grid. In order to perform the effective operation of the lead-acid battery, SOC and life cycle evaluation algorithm is required. Specific gravity with the change of electrolyte temperature inside battery case should be obtained to evaluate the SOC of lead-acid battery, however it is difficult to measure the electrolyte temperature of sealed type lead-acid battery. To overcome this problem, this paper proposes the equation of thermal transmission to compensate internal temperature of the lead-acid battery. Also, it is difficult to exactly evaluate the life cycle of battery, depending on the operation conditions of lead-acid battery such as charging and discharging state, self discharging rate and environmental issue. In order to solve the problem, this paper presents the concept for gravity accumulation of charge and discharge cycle, which is the value converted at $20^{\circ}C$. By using the proposed algorithm, this paper propose the test device based on the Labview software. The simulation results show that it is a practical tool for the maintenance of lead-acid battery in the field of industry.

This paper formulates a problem of embedded real-time system re-engineering, and presents its solution approach. Embedded system re-engineering is defined as a development task of meeting performance requirements newly imposed on a system after its hardware and software have been fully implemented. The performance requirements nay include a real-time throughput and an input-to-output latency. The proposed solution approach is based on a bottleneck analysis and nonlinear optimization. The inputs to the approach include a system design specified with a process network and a set of task graphs, task allocation and scheduling, and a new real-time throughput requirement specified as a system's period constraint. The solution approach works in two steps. In the first step, it determines bottleneck precesses in the process network via estimation of process latencies. In the second step, it derives a system of constraints with performance scaling factors of processing elements being variables. It then solves the constraints for the performance staling factors with an objective of minimizing the total hardware cost of the resultant system. These scaling factors suggest the minimal cost hardware upgrade to meet the new performance requirement. Since this approach does not modify carefully designed software structures, it helps reduce the re-engineering cycle.

Today the harbor oscillation problems are the most significant factor to design harbors serving the very large ships. Large vessels moored in the elastic hawsers at the coastal harbors are often displaced due to the resonance between the long period waves and mooring system. The cargo handling may be interrupted and the hawsers may be broken, especially when the amplification becomes remarkable. The most significant harbor which is confronted with harbor oscillation problem in Korea is the Pohang New Port. Many cases of problems are being notified by the pilot association and local office of MOMAF. However, it is difficult to prevent the arrival of long waves causing oscillation within this harbor. Moreover, Government already started new port plan at the mouth of YoungIl Bay without treating problems occurred in the Pohang New Port. This study deals with the variation of harbor oscillation due to the construction of 4.1km breakwater at the bay mouth and new port plan. Numerical method used are fairly standard form from the extended mild slope equation. The obtained numerical results were compared with the field measurement from the previous study and this will bring a certain level of discussion and consideration of variation in the future port development.

The purpose of this study is to develop the measurement of security needs satisfaction from users of electronic security system, to verify its validity and reliability, and by applying them, to examine the effects between the communities using this system. In 2008, the users of electronic security system in big cities in Seoul(Yong-San, Jong-Lo) and Gyung-Gi Do(Su-Won) for their convenience stores, jewelry shops, communication services, banks, government and public offices, etc. were arranged for a population and 262 of them were used for the final analysis by purposive sampling. This study yields following results. First, the validity of security need satisfaction from users of electronic security system is very high, which means the explanatory adequacy of environmental security need is the highest. Second, the reliability of security need satisfaction from users of electronic security system is very high, in which the reliability value(Cronbach's $\alpha$) of internal consistency is over .765. Third, the security need of electronic security system has the most effects on the group of bank workers. That is, through a close cooperative system between the bank and the service of electronic security system, the more keeping satisfied the environmental, bodily, physical security needs are, the less the in security of this group has. Informational security need has the most effects on convenient store group. It means the service companies of electronic security system offer more services at dawn time and make or supply all sorts of visual information system, which reduces insecurity of the convenient store group.

Objectives: This study investigates the factors influencing values on life-respect among middle school students. Methods: The participants in this study were 126 students from S middle school and Y middle school, both located in Gyeongnam province. The experimental group consisted of 40 students from S middle school, Control group-Iconsisted of 39 students from S middle school, and Control group-II consisted of 47 students from Y middle school. The experimental group was provided with 12 incidences of the life-respect education program from April 1st to June 29th. One period took 45 minutes and proceeded according to a structure of introduction, development, and consolidation. The experimental group received a life-respect education program, Control group-I received health teaching, but Control group-II didn't receive any special education except what was regularly part of their curriculum. The content of the life-respect education program included the following topics: value of life-respect, respect for human life and ethics, life-respect campaign, having a healthy mind, suicide prevention, dealing with crisis, prevention of school violence, abortion and life-respect, social weak minority consideration, death, brain death, euthanasia, life cycle and task, and forest activities. Questionnaires were administered as pre and post-tests which consisted of questions regarding death anxiety, suicide risk, and values on life-respect. The pre and post-tests were analyzed with t-tests, paired t-tests, ANOVAs, and factor analyses using SPSS 18.0. Results: 1. There was a statistically significant increase in the experimental group(p<.0001) and control group-I(p<0.05) in value and attitude about life-respect. On the other hand, it was shown that there was no difference between pre and post-test in control group-II. 2. The result of examining the differences between pre and post-tests after education on values and attitudes toward life-respect using ANCOVA showed, there was a statistically significant difference (p<0.001) among the three groups. Conclusion: the life-respect education program which was conducted over 12 meeting with middle school students had an positive effect, which can be used as basic data for fostering values on life-respect. These findings indicate that the life-respect education program this study used is effective for fostering value of life-respect and decreasing suicide risk.

In the early industrial age which with high intensity of machine and labor, using financial measurement index was good enough to tie in company's mechanization and philosophy of management and been in efficiency. But being comply with "New Economic age," a new economic environment is full of knowledge and information, the enterprise competition had changed from tangible assets, plants to intangible innovation ability of knowledge. As recognizing the new tendency by enterprise, they value gradually the growth and influence from learning. Practice of organization learning not only needs firm structure and be in coordination with both hardware and software, but also needs an affect measurement model to offer enterprise to estimate learning performance. It's a good instrument of financial performance measure mold in the past years, But it's for measuring the past, couldn't formulate enterprise trend to future, hard to estimate investment for future, such as development of products, organization learning, knowledge management etc, as which intangible assets and knowledge ability just the key factors of being win around competition environment in the future. In 1992, Kaplan and Norton brought up Balance Scorecard (BSC) on Harvard Business Review, as an instrument helping enterprise to measure performance, which is being considered to be a most influence management instrument. It added non-financial index such as customer, internal process and learning growth besides traditional financial index, as offering enterprise an index to measure and manage intangible assets and intellectual property. As being aware of organization learning is hard to be ignored in the new economic age, this research is based on learning and growth of BSC, and citing one national material company try to let the most difficult measurement performance of organization learning, to be estimate through BSC, analyze of factor and individual case, to discuss the company how to make the related strategy and vision of organization learning to develop learning and growth of the structure of BSC, subject the matter of out put factors to be discussed, and measure the outcomes as a result of research. The research affect offers (1) the base implement procedure of carrying out BSC; (2) the reference of formulating measurement index while enterprise using BSC to estimate performance of organization learning; (3) the possibility bottleneck maybe forcing while carrying out BSC, to be an improvement or preventive for enterprise.
