The purpose of this study are to evaluated bond, flexural properties and control of plastic shrinkage cracking of crimped type synthetic fiber with amplitude 6 mm and height 1.8 mm reinforced cement based composites. Bond and flexural test were conducted in accordance with the JCI-SF 8 and JCI SF-4 standard, respectively. The plastic shrinkage cracking test was conducted for evaluating the effect of fiber in reducing shrinkage cracking in cement based composites. Test results indicated that the crimped typel synthetic fibers performed significantly better than the straight type fiber in terms of interface toughness and pullout load and the crimped type synthetic fibers improved the flexural toughness of concrete. Also, the increasing the crimped type synthetic fiber volume fraction from 0.00% to 1.00% improved the plastic shrinkage cracking resistance. Specially, the effect of control of plastic shrinkage cracking is excellent at the more than 0.5% fibre volume fraction.

These days, hospitals in Korea have great interests in healthcare accreditation. The criteria of this accreditation has been established by management, but development of the management system without facility improvement has limits. Therefore this study reclassified domestic and foreign healthcare accreditation focusing on facilities and has purpose on proposing facility elements that can be adopted in hospitals. Also, the study is relevant to the study on architecture planning of hospital according to 'Patient safety' which will be suggested in the future and has significance for establishing basis of healthcare facility planning and for improving the existing facilities. The study selected facility lists from 'healthcare accreditation' and reclassified them based on departments in the hospital. Using these lists, the study divided the hospital that has obtained 'healthcare accreditation' into departments and investigated and analyzed them. On the basis of the analysis, the study suggested facility lists involved in hand washing, waste disposal, equipment washing, quarantine, goods-movement, establishing clean/polluted area, emergency exit-way, and restricted zone.

Purpose: This study was done to identify the relationships of perception of JCI (Joint Commission International) hospital accreditation, nursing performance, self-concept and retention intention in nurses. Methods: Self-administered questionnaires were used to collect data from 199 JCI-accredited nurses in general hospitals located in Gyeonggi Province. Data collection was done in May 2015 and analyzed using t-test, ANOVA, $Scheff{\acute{e}}^{\prime}s$ test, and Pearson correlation coefficients. Results: The scores for perception, and nursing performance were (on a five-point Likert scale) 3.34, 3.78 respectively, and self-concept and retention intention were (on a eight-point Likert scale) 5.40 and 5.21 respectively. Nurses' perception, nursing performance, self-concept, and retention intention showed significant differences depending on age, marital status, education, department, work experience, position, Korean accreditation, and JCI accreditation. A positive correlation was observed between perception, nursing performance, self-concept, and retention intention. Conclusion: The results of this study indicate that enhancing positive perception and good nursing performance can produce good self-concept and retention intention.

A reference diffusion coefficient model from ACI life-365 is drawn from test results by NT build 443. This test method gives a time-averaged diffusion coefficient during immersion period, thus the ACI model uses the time-averaged diffusion coefficient as a reference value. ACI model needs to be revised, considering the difference between the time-average value and reference value at specified time. In this study, firstly the analytic solutions of diffusion equation are derived considering the initiation time and period of exposure to chloride, and secondly the time-averaged diffusion coefficient from NT build 443 is converted into the diffusion coefficient at reference time. From this study, the reference diffusion coefficient of ACI model should be modified to be about 10% larger values than those of present ACI model. For convenient design of service life, previous relationship between the chloride diffusion coefficient from NT build 443 and that from NT build 492 is also modified. To compare the chloride diffusion coefficients of ACI and JCI models, the reference chloride diffusion coefficient with respect to the JCI model is drawn in the similar form of ACI model's, and service life prediction by ACI life-365 method is confirmed to give a conservative result.

Purpose: This study was conducted to identify factors affecting nurses' organizational commitment of the JCI. Methods: This cross-sectional study was performed using questionnaire. Data were collected from 198 nurses who worked at one hospital from 5 to 14 May 2013. Tools were used general characteristics, perception(Yang & Choi, 2014), job stress(Park, 2005), organizational commitment(Mowday, Porter, & Steers, 1979). Results: The scores of perception, job stress, and organizational commitment of the JCI were 3.21/5, 4.08/5, and 2.65/5 respectively. Organizational commitment was significantly different according to degree. A positive correlation was observed between perception and organizational commitment. Organizational commitment was negatively correlated with job stress. The explained variances for organizational commitment was 26.3% and factors affecting nurses' organizational commitment were degree, perception, and job stress. Conclusion: These results showed the significant factors for nurses' organizational commitment of JCI. These findings can be utilized to development of strategies for reducing job stress, and enhancing perception of JCI.
