The purpose of this study is modeling nursing competencies and reasoning out the core competencies, the ability for 20% of important actions for nursing jobs which can manage the rest 80% so that the competency-based nursing curriculum can be developed. A literature review of the vast studies regarding competencies was done to understand the concepts of competency-based curriculum, competency, and nursing competencies, identifying the relationships among each nursing competency categorized in accordance with those concepts. An exemplified concept map of core competencies for the competency-based nursing curriculum is suggested based on a thorough review of various competency modeling methodologies. The core competencies consist of base competency (theoretical/practical nursing knowledge and skills), practical competency (clinical judgment, patient education, communication, etc.), and personality competency (leadership, sense of responsibility, cooperation, etc.). The circular relationship among them can remain consistent through self-directed learning and critical thinking. Therefore, a nurse who have those core competencies is a knowledge worker, a self-directed learner, and also an effective, professional communicator. Further studies which solidify the concept of nursing competencies should be done, as well as the feedback procedures which evaluate the program outcomes and then reflect the evaluation results in the curriculum should be followed continuously.

Recent changes in the industrial parks have become a major issue in the nation's economic aspect. However, the industrial park's structure-advance projects under regional changes have excluded the surrounding spaces. The purpose of study is to analyze physical characteristics of Industrial park and adjacent area and to propose practical urban linkage alternatives as place-making It was found that in an urban aspect, the industrial parks belong within the city, but look like an isolated island that doesn't belong to a city. Therefore, as a way that could improve the problems above, and prevent the formation of heterogeneous spaces, the deliberate management of Industrial park's structure-advancement projects is needed. As one of these measures, It is concluded that the review of designating industrial facility zones which is a district unit plan and managing the detailed elements of construction to the various elements of the district level are needed.

Korean government has operated EA by the act on efficient introduction of information system and operation, etc. But the evaluation system for EA and the criteria don't prepare well. Particularly, There is no model for EA performance measurement and the way is insufficient. In this study, we derived 8 areas and 17 criteria for the performance evaluation based on the Performance Reference Model of U.S FEA and Korea. And we also derived 8 areas and 10 criteria for it based on the OMB EA Assessment Framework and the EA maturity model in Korea. We propose the performance evaluation model of the five areas that consists of the business performance, customer performance, process, human resource and the technology for EA performance evaluation. To verify the model, we applied the model to three organizations and evaluated EA performance. In addition, we compared the performance result with the performance evaluation area of EA maturity model of Korea to verify the result. We also analyzed the criteria of the proposed performance evaluation model with the current EA maturity model and Performance Reference Model of Korea. As a result of the evaluation, we verified of the proposed performance evaluation model, too.

Since computer became available, much effort has been made to achieve information security. Even though memory protection defense mechanisms were studied the most among of them, the problems of existing memory protection defense mechanisms were found due to improved performance of computer and new defense mechanisms were needed due to the advent of the side-channel attacks. In this paper, we propose JMP+RAND that embedding random values of 5 to 8 bytes per page to defend against memory sharing based side-channel attacks and bridging the gap of existing memory protection defense mechanism. Unlike the defense mechanism of the existing side-channel attacks, JMP+RAND uses static binary rewriting and continuous jmp instruction and random values to defend against the side-channel attacks in advance. We numerically calculated the time it takes for a memory sharing-based side-channel attack to binary adopted JMP+RAND technique and verified that the attacks are impossible in a realistic time. Modern architectures have very low overhead for JMP+RAND because of the very fast and accurate branching of jmp instruction using branch prediction. Since random value can be embedded only in specific programs using JMP+RAND, it is expected to be highly efficient when used with memory deduplication technique, especially in a cloud computing environment.

Recently, neural network research for forecasting the consecutive controlling rules of the future is being progressed, using the series data which are different from the traditional statistical analysis methods. In this paper, we suggest the pruning algorithm for the fast and exact weather forecast that excludes the hidden layer of the early optional designed nenral network. There are perform the weather forecast experiments using the 22080 kinds of weather data gathered from 1987 to 1996 for proving the efficiency of this suggested algorithm. Through the experiments, the early optional composed $26{\times}50{\times}1$ nenral network became the most suitable $26{\times}2{\times}1$ structure through the pruning algorithm suggested, in the optimum neural network $26{\times}2{\times}1$, in the case of the error temperature ${\pm}0.5^{\circ}C$, the average was 33.55%, in the case of ${\pm}1^{\circ}C$, the average was 61.57%, they showed more superior than the average 29.31% and 54.47% of the optional designed structure, also. we can reduce the calculation frequency more than maximum 25 times as compared with the optional sturcture neural network in the calculation frequencies.

In this study, the effect of polypropylene fiber on the freeze-thaw damage of mortar was evaluated experimentally. The effects of the reinforcing of polypropylene fiber on the compressive and bending performance of mortar after 300 cycles of freeze-thaw test were evaluated by comparing the normal mortar and the mortar with polyvinyl alcohol fiber. In addition, the mass loss, relative dynamic elastic modulus, and cumulated pore volume of mortar were measured by each cycle of freeze-thaw test. As a result, it was confirmed that the fiber reinforced mortar, regardless of the fiber type, was effective not only in maintaining the performance of the compressive strength and the bending strength but also suppressing the mass loss after the freeze-thaw test of 300 cycles. Meanwhile, it was confirmed that not only polyvinyl alcohol fibers but also polypropylene fibers can effectively act to suppress the damage of the mortar by freeze-thaw. However, in order to improve the freeze-thaw resistance of mortar mixed with polypropylene fiber, it is necessary to increase the bonding performance with the cement matrix which can be expected from polyvinyl alcohol fiber.

In this study a computerized prototype system was developed with Safety Management Information System(SMIS version 1.0) as a main system and database as subsystems to handle information. Safety management information consists of management aspects and technical elements, but SMIS consists of 4 modules of technical elements to interrelate safety technologies closely. SMIS enables gas industries to manage process safety information effectively and to evaluate hazards. The results from SMIS can be used to the operation manual and the emergency plan. Data base consists of 3 modules of accident data, material data, and equipment data to support SMIS. Also, the case study results proved the usefulness of SMIS for searching and accumulating process safety data. Especially, MIS which has the database suggests a formal structure for scattered raw safety data in gas industries and brings reduction of man power and time.

The effects of hurdle techniques on the reduction of Bacillus cereus spores in Doenjang and Gochujang were investigated. In our system, Bacillus cereus spores were artificially inoculated into Doenjang and Gochujang. Hurdle techniques used in this study were additives (3% ethyl alcohol-0.03% oregano extract), Joule heating ($95^{\circ}C$ for 5 min), and hydrostatic pressure (500 MPa for 5 min at $45^{\circ}C$). Additive-Joule (AJ) and additive-Joule-pressure (AJP) treatments for Doenjang resulted in a 2.80 log and 3.74 log reduction, respectively, while treatments for Gochujang resulted in a 4.71 log and 5.60 log reduction, respectively. This suggests a high synergistic effect of Joule heating with additive treatment in Doenjang and Gochujang. A combination ofg hurdles such as additives, Joule heating, and hydrostatic pressure also kept Bacillus cereus spore counts low during storage at $30^{\circ}C$. Therefore, Bacillus cereus spores inoculated into Doenjang and Gochujang can be effectively reduced through combined treatments, including AJ or AJP.

The purpose of the study was to examine nonpsychiatric physicians' attitudes toward psychiatry. 129 physicians responded to the questionnaire regarding attitudes toward psychiatry. A majority were favorable about psychiatric education, psychiatric consultation, psychoanalysis, students' choice of psychiatry as a career, and psychiatrists. Staff were more positive toward psychiatry than residents, and senior staff were more positive about psychiatry than junior staff. Overall, however, no significant differences were found in attitudes toward psychiatry between nonsurgical physicians and surgeons, although staff or residents in nonsurgical departments were more favorable about some aspects of psychiatry than staff or residents in surgical departments. The physicians with more interest in psychiatry as a career in the past were more likely to to be positive about psychiatry as a comprehensive science and a rapidly expanding field of medicine. Physicians with older age were more likely to be positive about status and efficacy of psychiatry, role and functioning of psychiatrists than those with. younger age. The results suggest that previous interest in psychiatry, age and clinical experience favorably influenced physicians' attitude toward psychiatry. In addition, development of models for psychiatric education will be needed to enhance physicians' attitude toward psychiatry.
