Recently, as there has been growing demand for aesthetic quality in structural materials, the development of excellent color cement concrete having good coloration properties has become a requirement. This study is designed to analyze the basic physical properties of mortar and the properties of keeping the coloration under an ultraviolet ray accelerated weathering test environment according to changes in the mixing ratio between carbon black and iron oxide used as colorants. The test results show that the use of carbon black and iron oxide reduces the initial flow by 6.3~17.2 % and the air content by 3.5~31.5 % but increases the unit volume weight by 3.4~5.5 %, compared to ordinary Portland cement (OPC). In addition, the study shows that the addition of iron oxide increases the self drying shrinkage. So, caution needs to be taken on the workability of the concrete. The brightness value L^⁎ represented by black showed the most excellent black colour when carbon black 3 % and iron oxide 5 % are added. According to UV accelerated weatherproof test, the brightness value L^⁎ was found to increase in all experiment specimens by 4.28~11.97 %, and the color change by UV was found to be higher for the case where carbon black colorant was not used. Therefore, in terms of color revelation characteristics, the case using carbon black 3 % and iron oxide 5 % was found to show the best black color.

Purpose: The purpose of this study was to identify whether hearing a recording of mother's voice affected physiological reactions, behavioral state related to sleep and weight of very low birth weight (VLBW) infants. Methods: This was a nonequivalent control group pre-post test quasiexperimental design. The participants were 11 VLBW infants in the experimental group and 11 in the control group. In the experimental group, a recording of mother's voice was played to her infant by voice recorder four times each day for five minutes over 10 consecutive days in the incubator. Results: For physiological response (heart rate, respiration rate, oxygen saturation), there were statistically significant differences between the experimental and control groups. Behavioral state during sleep was more very quiet and quiet in the experimental group. In the daily weight change, there was no significant difference between the experimental and control groups. Conclusion: The findings suggest that, for VLBW infants, the intervention of hearing a recording of mother's voice had some significance as a nursing intervention having a positive impact. Such interventions can help pediatric nurses to stabilize the physiological response and maintenance more very quiet sleep state and improve VLBW infants' growth.

Objective : The purpose of this study is to investigate the factors affecting occupational therapist's job stress through meta-analysis. Methods : In order to achieve the purpose of the study, 15 studies that examined job stress of occupational therapists were selected for analysis. The general characteristics of individual papers and the magnitude of the effect of related variables on job stress were calculated. The effect size of related variables on job stress and sub-factors (Fisher z) were calculated. Results : The results were found that the effect size on job stress was not significant in the variables of education level, salary and age. The largest effect size was found to be turnover intention (ES=1.161). There was no significant effect size in sub-factors of interpersonal conflict, organization system and insufficient job control. There was a significant effects in physical environment, lack of reward, job insecurity, job demand and occupational climate. Conclusion : The results of this study were suggested that an approach depending on sub-factors is needed to reduce job stress of occupational therapists. Satisfaction, burnout, and self-efficacy, which are psychological factors, are considered to be needed a program for psychological empowerment in order to reduce the job stress of the occupational therapist with a medium effect size according to individual sub-factors.

As CCTV can be an effective tool to prevent or suppress crime at low cost, they have been widesoread in developed countries. In spite of their effectiveness, they infringe some constitutional rights such as the right to privacy, the right of likeness and the right to control over personal information. The police and ward offices install CCTV in public areas to prevent crimes without a legal basis or standard. When information obtained in such a way is used as investigation data for the police or as an evidence in a court, it can cause serious trouble. To solve this problem, legal restriction on the installation of CCTV as should be clearer. Since current laws on public agencies' protection of personal information are too general, they are not effective enough to protect personal information. Therefore, Personal Information Protection Organic Act should be enacted to make a legal basis for protecting comprehensive personal information. It should be obvious who installs CCTVs, who pay for the cost and how they are managed. Before installation, the police and ward offices should obtain residents' consent through a public hearing or voting (on the range and purpose of installation), or conduct an impact assessment. During installation, CCTVs should be limited to prevent or suppress crimes, keep public order and void dangers. In case of making a sign of installation, it must specify its rights. After installation(operation/management phase), they should abide by principles of information protection and try not to infringe constitutional right. In the cognitive aspect, the police should constitutional rights must be secured although it is important to carry out their missions. The police should serve citizens and change to the police of communities. Citizens should understand that constitutional right can be infringed if public order is not maintained. When citizens cooperate with the police, they fear of crimes will decrease.

The goal of this paper was to understand the skill-up experiences of ex-participants of the customized training program in Technical High Schools for Small and Medium Business during first 2 years in Company through qualitative interviews with 3 purposefully selected ex-participants. Their core skill-up experience in this period was assumed as the shift from' dependent worker' to 'independent worker' on the base of literature review. The results of this study were following : 1. The small and medium companies offered a few formal training for newcomers, production-site orientation through short job rotation, linking them with skilled workers and job manuals or job standards. 2. Authentic skill-up experiences were combined with a structured reprimand, peer learning, deep learning through reflection on one's own experiences. 3. There were a few handicap conditions that disturbed their skill-up activities: the skilled worker don't open their skill toward new corner; the ex-participants in company had no time to learn anything meaningful to up-grade their competency.

This study was performed to determine the depression and its association with sleep quality, occupational stress and fatigue among small-scale manufacturing male workers. The self-administered questionnaires were given to 856 workers under 50 members of manufacturing industries during the period from April 1st to June 30th, 2010. As a results, the distribution of depression group(21 point and over at CES-D score) among all subjects were 44.3%, and it was positively correlated with occupational stress, fatigue and quality of sleep. With the analysis of covariance structure, occupational stress(KOSS) was more influential on the depression than quality of sleep and fatigue. It was found to have the inter-relational effects that the higher the occupational stress(KOSS) and fatigue(MFS), and the lower the quality of sleep, the higher the depression. Thus the effective strategy for depression reduction among workers requires the efforts to improve the work environment and job contents.

IPTV has been drawing attention as a representative convergence media. The analysis of the convergence media, as like IPTV, requires an investigation into the use perception and multidimensional factors. So this research examines the IPTV usage, based on the Technology Acceptance Model. The analysis was made with the 500 users, based on the online survey. The first results is concerned with the user characteristics. A positive influential relationship between the user characteristics and use perception was confirmed, along with the individual attribute and environmental influence. The second, 'perceived ease of use' was found to positively influence 'perceived usefulness' and 'perceived playfulness'. This finding suggests that it is an important diffusion strategy to enhance the ease of use of IPTV. The third is the emphasis of playfulness of IPTV. Since IPTV is multimedia, playfulness played a significant role in diffusing IPTV. The application of the TAM to the media analysis of IPTV, which reflects the environments of the convergence media and use perception, was successful in drawing a significant outcome.
