Evaluation of chloride penetration is very important, because induced chloride ion causes corrosion in embedded steel. Diffusion coefficient obtained from rapid chloride penetration test is currently used, however this method cannot provide a correct prediction of chloride content since it shows only ion migration velocity in electrical field. Apparent diffusion coefficient of chloride ion based on simple Fick's Law can provide a total chloride penetration magnitude to engineers. This study proposes an analysis technique to predict chloride penetration using apparent diffusion coefficient of chloride ion from neural network (NN) algorithm and time-dependent diffusion phenomena. For this work, thirty mix proportions with the related diffusion coefficients are studied. The components of mix proportions such as w/b ratio, unit content of cement, slag, fly ash, silica fume, and fine/coarse aggregate are selected as neurons, then learning for apparent diffusion coefficient is trained. Considering time-dependent diffusion coefficient based on Fick's Law, the technique for chloride penetration analysis is proposed. The applicability of the technique is verified through test results from short, long term submerged test, and field investigations. The proposed technique can be improved through NN learning-training based on the acquisition of various mix proportions and the related diffusion coefficients of chloride ion.

In 1990 Home Care Education Programs started when legislation established certification for Home Care Nurses. The Ministry of Health and Welfare proposed a home care education curriculum which has 352 class hours and 248 hours of 'family nursing and practice'. Though Home Care Education Programs have been offered in 11 home care educational institutes, there has been no formal revision for the home care education programs. Also a first and second home care demonstration projects have been carried out, but there has been no research on outcomes for home care education as applied in home care practice. The purposes of this study were to identify the important content areas for home care nursing as perceived by home care nurses, and to identify their clinical competence in each of these areas, and from these to identify the education needs. The sample was 107 home care nurses who were working in home care demonstration hospitals and community-based institutions which have been offering home care services. Responses were received from 88 nurses, comprising a 82.2% return rate, and 86 were included in the final analysis. The instrument used was a modification of the instrument developed by Caie-Lawrence et(1995) and Moon's(1991) instrument on home care knowledge. The instrument's Cronbach's coefficient was 0.982. Among the respondents, 64% were working at home care demonstration hospitals and 36% were working at community-based institutions. Their home care experiences were from one month to six years, with a mean of 20.6 months. The importance rating for home care education content was 3.42 0.325, which means importance was rated relatively high. Technical aspects of home care were identified the most important. Five items 'education skill', 'counseling skill', 'interview skill', 'wound care skill', 'bed sore care skill' received 100% importance ratings. The competency rating was 2.87 0.367 and 'technical aspects of home care' was the highest, and 'application to home care skill' was the lowest. Home care nurses' education needs were identified and compared to the importance ratings and competency ratings. Eleven items were identified as the highest in the importance areas and eleven items were in the lowest competency areas. High importance ratings matched with low competency ratings determined training needs, but there was no matching items in this study. In the lowest competency areas four items were excluded, because of not being applicable in current home care practice. Therefore total eighteen items were identified as home care education needs. These items are 'bed sore care skill', 'malpractice', 'wound care skill', 'general infection control', 'change and management of tracheostomy tubes', 'CVA patient care', 'Hospice care', 'pain management', 'urinary catheterization and management', 'L-tube insertion and managements', 'Respirator use and management skill', 'infant care', 'prevention to burnout', 'child assessment', 'CAPD', 'infant assessment', 'computer literacy', and 'psychiatry patient care'.

We examined how science teachers in academic high schools perceived the 6th science curriculum and how they practiced under the curriculum. A nationwide survey was administered to obtain the responses from 402 teachers of 135 high schools. Most thought that the main themes of curriculum revision were well-embedded in the 'objectives', and that the 'content and content structure' were proper. However, they thought that the 'objectives' were not stated explicitly enough to develop teaching materials and to improve actual teaching and evaluation, and that some statements in the sections of 'method' and 'evaluation' were not proper if considered actual teachers' ability to teach inquiry and educational facilities. Many teachers also felt that the information about the curriculum was not sufficiently included at in-service teacher training programs, and that students' knowledge, attitude, and problem solving ability were not enhanced. Only few teachers were found to apply the STS approaches, reconstruct lessons, vary the structure of learning group, and develop evaluation tools with their colleagues. The lack of the practices was explained by entrance-examination-centered instruction and assessment, poor educational facilities, and lack of innovative teaching materials.

This study is a process to study the life drawing teaching method considering professional characteristics in animation and has a study objective to design the model and teaching method which applies the strategies considering the creative mechanism of the brain. Recently, study results about integrated teaching method are being announced which apply brain based learning principles as the alternative arguments about teaching methods in each area based on creativeness. In other words, integrated education based on creative mechanism in the brain is applied not only to fine arts and drawing education, but also to the entire areas of the arts. Life drawing is an area which demands comprehensive teaching method that vivid expressions could be skillfully obtained by understanding the communication methods with the objects through cognitive senses, creativeness and movements beyond the structural knowledge about human body. Therefore in this study, the strategies and methods for the skillfulness of life drawing and consequently arranged education model structure drawing are to be designed based on the creativeness, study materials and content factors which were analyzed in previous stages of this study. In order to combine the content factors based on creativeness and study materials of the brain which are the results of previous studies, the conclusion has been reached that 5 step cognitive strategy stages to wake brain senses, flexibilize the brain, purify the brain, integrate the brain and become the master of the brain. Strategic methods to execute this were designed with brain gym, right brain energization drawing and HSP(high-level cognizance) training. Teaching and learning model structure diagram which is designed based on this is to be continued to teaching and learning guidelines during the relevant semesters after the research.

This paper proposes how to improve performance of the Korean document sentiment-classification system using semantic properties of the sentiment words. A sentiment word means a word with sentiment, and sentiment features are defined by a set of the sentiment words which are important lexical resource for the sentiment classification. Sentiment feature represents different sentiment intensity in general field and in specific domain. In general field, we can estimate the sentiment intensity using a snippet from a search engine, while in specific domain, training data can be used for this estimation. When the sentiment intensity of the sentiment features are estimated, it is called semantic orientation and is used to estimate the sentiment intensity of the sentences in the text documents. After estimating sentiment intensity of the sentences, we apply that to the weights of sentiment features. In this paper, we evaluate our system in three different cases such as general, domain-specific, and general/domain-specific semantic orientation using support vector machine. Our experimental results show the improved performance in all cases, and, especially in general/domain-specific semantic orientation, our proposed method performs 3.1% better than a baseline system indexed by only content words.

The purpose of this study is to obtain basic information and implications for developing media information literacy curriculum by comparing and analyzing UNESCO's media and information literacy competencies and AASL's key competencies with the 2015 Revised Curriculum and the Library and Information Life curriculum. As a result of the analysis, First, UNESCO's MIL and AASL's key competencies in media information literacy were related to the competencies of the 2015 Revised Curriculum. Second, UNESCO's MIL included more aspects of the composition and competencies of information literacy than media literacy. For this reason, it could be said that media information literacy more appropriately reflects the content pursued by media literacy education than media literacy. Third, UNESCO's MIL included more training content for media literacy than information literacy. Fourth, the contents of media literacy were found to be insufficient in the Library and Information Life curriculum compared to the education contents of library and information literacy. Fifth, the competency standards related to media information literacy and Libraries and Information Life did not present cultural sensitivity competency. Based on the results of the study, It is necessary to develop a media information literacy curriculum that fuses the contents of media literacy beyond the information literacy that use library resources.

Since patients with strokes occupy a high priority among patients for home nursing, the development of guidelines for such nursing is required and the needs of these patients should be reflected in the guidelines. Therefore, this study was done to identify the content and levels of home nursing for patients with strokes and to utilize the data in developing the most effective home nursing guidelines for these patients. The level of A, D. L. and the ability to control upper extremities were measured, and through a questionnaire. the needs for home nursing and related variables were also evaluated. The subjects for the study were 121 patients, 58 inpatients and 63 home care patients who had had a Stroke. Data collection was done from September 1996 to January 1997. The collected data were analyzed utilizing SPSS /PC, and the results are as follows : 1. Home nursing need of inpatients The priority order of home nursing needs for inpatients was : "Training in emergency treatments and how to cope with a stroke"(2.28+1.06), next, "Explanation of diets as limited or recommended", and last, "Nursing care for sleeping Problems". 2. Home nursing need home of patients The priority order of home nursing needs for home patients was : "Care for the paralyzed side" (2, 89+.34), next, "Maintenance of right posture and how to change position" (2.87+.34), and last, "Counseling on sex". 3. Comparison of the levels of home nursing needs between in patients and home patients The results of analyses of home nursing needs according to causes were grouped into seven categories : and t-tests of the seven categories showed significant differences between the two groups in all categories, that is, the level of home nursing needs were significantly higher for home patients than for inpatients in all categories of home nursing. 4. Level of home nursing needs by characteristics The variables that have affected the level of home nursing needs for these patients were sex, profession, level of education, accompanying diseases, paralyzed position. A.D.L. levels and ability levels in coordinating upper extremities. There variables, displayed a reverse correlation with the level of home nursing needs, and the degree of correlation was high. In conclusion, the above results, show there were differences in the priority order of home nursing needs between inpatients and home patients : but the content of home nursing needs wanted by these patients was similar. Meanwhile, the levels of demand for home nursing was exceptionally higher on the part of home patients than inpatients. Although it is realized that nursing guidelines for home nursing needs in all items need to be developed, there is also a necessity to guidelines in accordance with priority orders, and with consideration of the factors that affect the level of home nursing needs. of the factors that affect the level of home nursing needs.

A central issue in the development of nursing practice is to describe the phenomenon with which nursing is concerned. To identify the health problems which can be diagnosed and managed by the nurse is the first step to organize and ensure the development of nursing science. Therefore the academic world has been discussing the application of the nursing diagnosis in nursing practice as a means of improving quality of care. The objectives of this study were to develop a standardized nursing care plan for ten selected nursing diagnoses to form a database for computerized nursing service. The research approach used in the study was (1) the selection of the ten nursing diagnoses which occur most frequently on medical-surgical wards, (2) the development of a standardized nursing care plan for the ten selected nursing diagnoses, (3) application of the plan to hospitalize patients and evaluation of the content validity by the nurses, and (4) evaluation of the clinical effects after the use of the standardized nursing care plans. The subjects were 56 nurses and 395 hospitalized patients on two medical and two surgical unit. The results of this study were as follows ; 1) The ten selected nursing diagnoses for the development of the standardized nursing care plans were “PAIN, SLEEP DISTURBANCE, ALTERED HEALTH MAINTENANCE, ALTERATION IN NUTRITION, ANXIETY, CONSTIPATION, ALTERED PATTERNS OF URINARY ELIMINATION, DISTURBANCE IN BODY IMAGE, POTENTIAL FOR ACTIVITY INTOLERANCE AND ACTIVITY INTOLERANCE”. 2. The developed standardized nursing care plans included the nursing diagnosis, definition, defining characteristics, etiologic or related factors that contribute to the condition, recording pattern, desired outcomes and nursing orders (nursing interventions). 3. The plan was used with hospitalized patients on medical - surgical wards to test for content validity. The patient's satisfaction with the nursing care and nurses' job satisfaction were investigated to evaluate the clinical effects after the use of the standardized nursing care plans. A comparison of patient satisfaction with nursing care before and after the introduction of the standardized nursing care plans showed a statistically significant higher level of satisfaction with the standardized care plans. There was no difference in the level of job satisfaction expressed by the nursing staff before and after the standardized nursing care plans were introduced. However, when opinions about the use of the standardized nursing care plans were examined it was found that there was a positive effect on clarity in defining the nursing problems, determining nursing cost, more feasible goal setting, effective and systematic nursing records and indications for nursing research. The results of this study suggest that in order to increase the use of nursing diagnoses in the clinical area, it would be effective to select some wards as a pilot project, give the nurses training in the use of nursing diagnosis and develop and use the standardized nursing care plans. In addition to the ten diagnosis used in this study it is recommended that continual development of nursing diagnoses be done using diagnoses that are appropriate to Korea and testing them for validity through standardized care plans.

This study investigated contents of mission statements for Strategic Management of hospitals in Korea and Japan. For the study, 44 tertiary care hospitals in korea, which were accredited by the Ministry of Health and Welfare, were selected. And 83 special functioning hospitals in Japan, which were approved by the Minister of Health, Labour and Welfare, were included. Both quantitative and qualitative analyses were conducted by classifying 5 components of the mission statement; market, service, philosophy, image, contribution. Findings from this study are as follow. First, hospitals in Korea emphasized image(93.2%) and philosophy(81.8%) components in their mission statements, whereas hospitals in Japan highlighted components of service(89.2%) and market(72.3%). In detail, mission statements of Korean tertiary care hospitals describe the components of hospital's image (93.2%), philosophy(81.8%), contribution(56.8%), market(22.7%) and service (18.2%) in order. On the other hand, mission statements of Japanese special functioning hospitals describe hospital's service(89.2%), market(72.3%), contribution(61.4%), image (49.4%) and philosophy(34.9%), respectively. Second, as results of Content analysis, there were some differences in mission statements of hospitals between two countries, and it is mainly from the divergences of standards for recognition of medical institutions, environmental factors, and different ways of mission statement description. For strategic hospital management, carrying out innovative restructuring organization or promoting of research and training for medical development is considered as a desirable approach. However, clear description of mission statement is more important and it is required for effective control and managing organization. And then the mission should be communicated within an organization so all internal members understand it and put their efforts to achieve the mission of organization. In conclusion, it is recommended that a leader and senior managers should re-evaluate its mission statement whether it reflects characteristics of an organization. In addition, a mission statement should be created or improved based on critical decision, as well as it should be clearly shared within an organization in order to become a future oriented organizations.
