Technology-driven development of a new system makes it difficult for users and stakeholders to identify or intervene in the development process, resulting in systems with unnecessary functions and poor quality services. Applying the software architecture design process to the initial design of the navigation system platform of autonomous ships enables the development of a system that reflects the required functions and service quality of the stakeholders. The design, which includes all of the subsystems that make up an autonomous ship platform, is close to an enterprise architecture. Thus, we strived to design a navigation system platform suitable for the design range of the software architecture. This study analyzed the definition of functional requirements, and quality attributes by applying the software architecture design procedure. This study was conducted to identify the characteristics of the navigation system and platform needs, and the stakeholders were identified. To derive the functional requirements and constraints of the platform, a quality attributes workshop was held engaging stakeholders, and the results of the analysis of functional requirements and quality attributes were listed. Based on the results of this study, the architect can establish the evidence and technical solutions that are integral for the architecture development, and will facilitate the creation of quality attribute scenarios.

Self healing systems are considered as cognation-enabled sub form of fault tolerance system. But our experiments that we report in this paper show that self healing systems can be used for performance optimization, configuration management, access control management and bunch of other functions. The exponential complexity that results from interaction between autonomic systems and users (software and human users) has hindered the deployment and user of intelligent systems for a while now. We show that if that exceptional complexity is converted into self-growing knowledge (policies in our case), can make up for initial development cost of building an intelligent system. In this paper, we report the application of AHSEN (Autonomic Healing-based Self management Engine) to in OKKAM Project infrastructure backbone cluster that mimics the web service based architecture of u-Zone gateway infrastructure. The 'blind' load division on per-request bases is not optimal for distributed and performance hungry infrastructure such as OKKAM. The approach adopted assesses the active threads on the virtual machine and does resource estimates for active processes. The availability of a certain server is represented through worker modules at load server. Our simulation results on the OKKAM infrastructure show that the self healing significantly improves the performance and clearly demarcates the logical ambiguities in contemporary designs of self healing infrastructures proposed for large scale computing infrastructures.

There are two main parts to improve the quality and the efficiency of railway service. One is to acquire the system with high RAMS performance and the other is to keep it up. Therefore we need to specify RAMS requirements in the system specifications and verify them. In addition, it is necessary to monitor RAMS and to make operation and maintenance policies based on RAMS. This article presents RAMS centered maintenance procedure of which target is to continuously achieve the inherent RAMS performance of the acquired system. The method to evaluate the effect on RAMS and the conceptual optimal model for determining maintenance interval are also proposed.

As the development environment is changing with the development of information communication technology, the systems that were used by each service became used with integration. In the process of integrating from existing legacy systems to new system, it should be smoothly integrated or shared, however, it cannot help holding existing technology or component due to significant cost burden for conversion. In this paper, it was not only classified by types with analyzing the various elements that make up legacy system but an approach and monitoring system were developed to each type. After System application results, data's information generated in each process is provided to other system in real time, so that it has not only secured the work efficiency and reliability but also it is made possible by integrating data in various formats for efficient data management, rapid search and tracking to history. With real-time monitoring system developed in this study, It can be very useful in a variety of industries which require real-time monitoring of distributed legacy system data.

Emulab is a research framework developed by Utah university, proving on-demend research environment service so that researchers can set up and use the environment at anytime. The main advantage of Emulab over other research methodologies like simulation or virtualization is to use real systems and networks using real operating systems, making the research environment much similar to the real world. Even though Emulab has been actively used in many areas such as security and network, there has been little use in Korea research community. As KISTI recently constructed a small Emulab, it is expected that many researchers and educators would make use of the Emulab. In this study, we introduce Emulab to Korea research community and give an overview of utilization trend of Emulab as a cyber security research framework.

The thesis suggests the proper ftaining methods and their future direction in order for bodyguards to have a general idea of basic skills of escort and develop them. What is meant by basic skills are the basic abilities of bodyguards for escort indluding physical strength, martial arts, and manipulation of equipment. The equipment in the thesis is confined to guns. The following are the requircments for the training of basic skills; 1, A bodyguard should be careful not to expose any equipment he uses his basic skills so that he does not make others feel uncomfortable. 2. He should be trained to give the safety of the person(s) escorted the first priority. 3. He should have the ability to take care of at least one attacker. 4. He should be trained to be able to evaluate the trend of attacks and keep up with it. Training fo basic skills are divided into three parts-physical training, martial arts and use of equipment. Each part is divided into basic training, applied training, and professional training, which again are integrated in one master training program. Especially, development of equipment which helps to take care of attacker(s) quickly without casualties and learning to use the equipment efficiently will accelerate the improvement of basic skills. The author of the thesis worked for Presidential Security Service for fourteen years and suggests the most efficient, protection-oriented way of training based on his experience.

Medical demand has been increased explosively since health insurance was introduced in 1977. Person has taken a growing interest in increase of medical service supply while that period. We must understand the legal aspects of medical quality management. There have been many legislative efforts for securing the right of patient. Patient's legal right is secured through the declaration of patient's right and all hospital person deal with patients according to the standard and criterion of the declaration of patient's right. The patient's right is set up on a basis of the right to live and the expectation right of patient. It is important to prevent medical accidents because the right of patient's health is violated by medical accident. We must manage well the medical quality to prevent the medical accident. The effort to escalate the medical quality is the best method to decrease the medical dispute. Nowadays a person take a growing interest medical quality. Our government make an effort to secure the medical quality through the legal system to be contained health organization evaluation system.

As the IT technology develops there is a service on internet in which the herbal treatments from medicinal classics can be found in a form of a database. If an assay, and a verification on individual informations on materia medica and the herbal treatments from medicinal classics is established, it would be an enormously efficient asset for the formation of new treatment as well as interpreting the basic information on the efficacy of a treatment. If asp.net is used to make such a system, the user can have access to the informations on materia medica and its treatment without having to setting up a separate system, and especially the user can attain visual information on the genealogy of the herbal treatments in its formation. However, there is a need to develop a more efficient program in terms of organizing the informations on herbs and herbal treatments.

Health insurance review & Assessment service (HIRA) has enforced cutting the drug costs when physicians prescribe split extended release drugs, starting from December, 2010. The objective of this study is to analyze extended release and enteric coated drugs on pharmaceutical reimbursement list in Korea, and to investigate the impact and barriers of the health insurance review on splitting extended-release formulation drugs. By using the ingredient code, extended release and enteric coated formulations make up 7.8% of all drugs in April, 2011. The most frequently used drugs are agent affecting circulatory and digestive system. From the extended release and enteric coated formulations (n=112), 34.8% (n=39) were not available in other dosage forms. According to questionnaire survey for 169 pharmacists (response rate: 73.8%), the rate of splitting and crushing of extended release and enteric coated drugs decreased. When pharmacists correct physician's prescription errors, the biggest problem was lack of other dosage forms. So it is necessary to develop variety of other dosage forms, and computerized checking system for splitting extended-release drugs. It is also important to inform physicians and patients in regard to the problems of split prescription of extended release and enteric coated drugs.
