While the existing Web focuses on the interface with human users based on HTML, the next generation Web will focus on the interaction among software agents by using XML and XML-based standards and technologies. The inference engine, which will serve as brains of software agents in the next generation Web, should thoroughly understand the Semantic Web, the standard language of the next generation Web. As abasis for the service, the W3C (World Wide Web Consortium) has recommended SWRL (Semantic Web Rule Language) which had been made by compounding OWL (Web Ontology Language) and RuleML (Rule Markup Language). In this research, we develop a backward chaining inference engine SMART-B (SeMantic web Agent Reasoning Tools -Backward chaining inference engine), which uses SWRL and OWL to represent rules and facts respectively. We analyze the requirements for the SWRL-based backward chaining inference and design analgorithm for the backward chaining inference which reflects the traditional backward chaining inference algorithm and the requirements of the next generation Semantic Web. We also implement the backward chaining inference engine and the administrative tools for fact and rule bases into Java components to insure the independence and portability among different platforms under the environment of Ubiquitous Computing.

This study is primarily concerned with the criteria for choosing a legitimate state plaintiff in cases involving a states request to media for a right of reply. Interpretation of the right of reply itself is different from country to country because of different constitutional views and systems in each state. Unlike the United States, the constitution of the Republic of Korea does not expressly prohibit the making of laws adversely affecting freedom of the press. Accordingly, in Korea freedom of the press may be restricted through legislation within certain limits and the right of reply is not incompatible with the spirit of the constitution. An analysis of relevant law makes it clear that the particular agency aggrieved should initiate the suit rather than the Justice Minister. The idea that the Justice Minister should assume the role of plaintiff in all state cases seems to stem from flawed interpretations of provisions in the Law Governing Registration of Periodicals and the Law Governing Litigation Involving the State. Even though each state agency has the right of reply, it should be cautioned not to abuse it as the states frequent involvement in litigation may bring on unnecessary misunderstanding and have a chilling effect on the media. The right of reply does not always imply that a certain media report in question is wrong and the media should be sanctioned for it. The right of reply is basically intended to help the general public make an informed judgment on issues presented in the media and insure fairness and balance.

To insure nuclear reactor safety, the reactivity of control rods should be calculated by measuring the criticality of reactor core and it is regularly performed during the annual physics test period. Also, the core criticality should be monitored during the start-up operation to avoid reactivity induced accidents. Many research works on control rod reactivity measurement and subcriticality measurement have been accomplished throughout the world for decades and recently a new method named "Modified Neutron Source Multiplication Method (MNSM)" was proposed in Japan which is known to be improved overcoming limitations of traditional Neutron Source Multiplication Method (NSM). In this study, MNSM was tested in calculation of subcriticalities and in evaluation of application validity using the educational reactor in Kyung Hee University, AGN-201. For this study, a revised nuclear data library and a neutron transport code system TRANSX - PARTISN were established. Correction factors for various control rod positions were produced using the k-effective values and the corresponding flux distributions and adjoint flux distributions. Experimental values of the core criticality were obtained using the neutron count rates of the BF3 proportional counters. The results showed that the expected reactivity worth of control rods by MNSM agreed well with the theoretical values and the correction factors contributed much for this purpose.

The mediacy is now evolving with the development of mankind civilization. In the evolution, mediacy shows duplicate logic of remediacy with the opposite mediacy property between immediacy and hypermediacy. The duplicate logic of remediacy is defined as a result of hypermediacy which clearly requires transparency and absorption of immediacy. Because of changes from analog to digital age and the development of image technique, At present, the era is coming when the splendid and spectacle visual speaks for the screen not well-organized script and direction. With this developing period, the research for visual effect is actively performed and advanced to the new study. Though the study of visual effects contains the hypermediacy trait, it is also conjugated as a research field for immediacy on the screen which is the wish of content production directors. In this study, the analysis of case study for the movie "The Lord of The ring"'s visual effect application is carried out. Also, it is investigated that visual effects can guarantee for the verification of valuable new research filed which insure transparency and absorption in the hypermediacy results. Furthermore, on this study, it is executed for the contribution of the identity and systematization in the new research field "Visual Effects".

In this study, a portable flashlight which can manually generate the electricity by using sunlight was developed so that it can be used in the extreme environmental condition such as no-electricity condition. Battery is charged by using solar battery during the day, but when sunlight is not avalible during the night or rainy day, a handle is rotated to generate the electricity in order to charge the battery manually. To improve the brightness of the light, light is concentrated by using the optical lens. Low electric consumption circuit is used for the longer operating time by suppress electrical consumption while lamp is discharged. A circuit is designed and used for steady electrical curris dand voltage to insure steady battery charging. Super-discharge circuit and protection circuit are used for the super discharge of battery when it is not used for a long time. Also the constant charge is possible by using houseware adapter. As a result, a portable flashlight is designed to charge with sunlight during day, and with houseware adapter during night. A portable flashlight is also designed to irradiate longer distances by improvement of the brightness of the light using the optical lens. Thus, it forms white natural ray of light making possible for night reading.

In recent times, sea level increasing caused by abnormal weather and global warming, sea-sand dredging and complex development causes various kind of erosion damages onto the coastal area in the world. The various types of erosion control and protection methods are applied but there are no signs of fruitful effectiveness. The PC concrete protection block for shore protection structure is practically installed in globally but most of structures in the present day became villainous because of bad accessability. In this study, hydrophilic revetments for control and protection of coastline erosion will be developed in order to make up for a faculty of the shore erosion protection block with better accessibility and excellent protection ability. Experimental measurements were researched to insure for the capacity and facility on reflection coefficient, overtopping volume, and overtopping height characteristics of newly developed shore erosion protection block in model tests. As the result, hydraulic model tests show much excellent than the general step block. Field tests were carried out also to verify through vegetative test on an affinity and construction work test of control-protection on coastline erosion with actual utilization. In the latter case, deposition of sand accumulation occurred in fairly short time at the established reaches and then we can be confirmed to utilize for newly developed block as the revetments for control and protection of coastline erosion.

In this study, butane 100% was used as fuel to verify the real fuel effect such as vapor pressure variation due to temperature change. A MPI fuel injection system for V-6 engine, which has reverse 'L' type cross section to minimize the possibility of liquid phase injection, was composed and one bank was operated under sequential injection scheme. Flow rate were measured according to injection duration, interval, and pressure. Also occurring of liquid phase injection was monitored with varying vaporizer and fuel rail temperature. The result shows that basic characteristics of injection is a relatively difference between air and LPG injection. Under cold start condition, however, the occurrence of liquid injection becomes more severe as the pressure increases, and sufficiently high temperature both in vaporizer and fuel rail is very important to insure gaseous injection. In addition, the temperature of vaporizer plays more important role in keeping LPG vapor state and the reverse 'L' type cross section of the rail is available to prevent liquid injection.

The purpose of this study was to analyze women's health problems using Green & Kreuter's(1991) PRECEDE model and to develop health education program for women's health. The subjects were recruited women from Wonju city 18 years or older. 1. The results showed that about 50% of the women were satisfied with their lives as women, 23% of the sample felt there was a need for a women's health care center. The mean number of health problems was 3.1 and the prevalence rate, 44.4%. 2. We developed on educational program according to group differences related to health problems, diagnosis of disease, variables influencing health promotion behavior, and programs which each group wanted. Also we stressed self-efficacy and self-help group for the management of individual health to all groups. 3. The diagnoses of diseases that were experienced premarital over the past year were gastritis, bronchitis, spinal disk, and fracture, for the childbearing/rearing group, gastritis, vaginitis and cervicitis, cervical cancer and cystitis and nephritis and arthritis and for the middle-aged/elderly group arthritis, gastritis, vaginitis and cervicitis, and spinal disk. Of the sample 30.5% did not have a health exam in the past year, and only 10% of the premarital group, 12.5% of the childbearing/child-rearing group, and 18.3% of the middle aged-elderly group were concerned about their health and did something for their health. 4. The average score on the HPLP was 2.41. the HPLP was scores according to group were found to have significant differences. self-efficacy, family functions, health attention and were considered important variables in the premarital group, in the childbearing/child-rearing group self-efficacy, family functions, internal locus of control, health attention, and health perception and power others locus of control and then for the middle aged-elderly group self-efficacy, health attention, internal locus of control, family functions and health perception. 5. There are a few educational programs in the city provided by the Wonju Health Center and by community health nurse practitioners. The premarital group requested the educational programs on diet, health exercise, family health and stress management. Also the childbearing/child-rearing group wanted programs on diet, family health, stress management, and health exercise, and the middle-aged/elderly group wanted that of family health, diet, climacteric changes stress management and health exercise. The program suggested that this program should be applied to women in the community to insure adequate management of women's health. Follow-up research with PROCEED is needed to analyze health outcomes, also, a women's health nursing specialist system is required to develop health promotion, and improve the quality of life for women.

The Ho-Rak controversy is an internal dispute in the Kiho School. Both Ho and Rak adopt the theories of Yulgok(栗谷) as their common standard of right arguments. The controversy continues almost two hundred years after the dispute between LEE Gan(李柬) and HAN Wonjin(韓元震). However, it does not develop rich theoretical resources. The fundamental issue of Ho-Rak controversy is how to define the relation of mind(心) and temper(氣質). Ho School regard temper as material of the mind, and so they insist that mind and temper are ultimately the same. But Rak School regard temper as desire of the body, and so they insist that mind and temper are the another one. The viewpoint of Rak School does not correspond to the view of the traditional Neo-confucianism. So we should understand that mind and temper are ultimately the same. However if we define that mind and temper are the same, and they act at the same time, then we can not insure the foundation of pure goodness in human mind. LEE Chulyoung(李喆榮) defines that mind and temper are ultimately the same, but they act alternately. It is the exact definition about the relation of mind and temper.
