Purpose: Population using complementary and alternative medicine (CAM) and the cost or it are increasing all over the world. In this study, we investigated the utilization state of CAM in the elderly people during the last 6 months of life. Methods: We found 4,210 persons in Seoul, older than 65 years who received a funeral subsidy from health insurance after death during the latter half of the year, 2001. We stratified them by age and gender and selected 301 persons and surveyed them by questionnaire. Results: 247 persons (83.1%) used at least one of CAM during their last 6 months of life. Diet and Nutrition remedy showed the highest utilatization rate (65.5%), and drug therapies also were much used (29.9%). Utilization rate was higher in female (60%) and according to the cause of death, the highest in a geriatric disease groups, and the lowest in the cancer group. Whole satisfaction to CAM was high with average 4.25 points out of total 6, and adverse effects were almost free with average 5.55 points out of total 6. Satisfaction was the highest in Diet and Nutrition remedy but the lowest in Manipulative and Body-Based methods. Adverse-effect score was best in Manipulative and Body-Based methods. According to age and the causative disease of death, there were significant differences in satisfaction and adverse effect levels. Conclusion: Majority of old people used at least one of CAM during their last 6months of life. Whole satisfaction and adverse-effect level were very excellent.

Improving public awareness of wood is essential for achieving the goal of establishing wood culture by expanding the use of wood. This study presents a basic examination of the strategy of revitalizing wood culture and a survey of its current status and requirements. The survey was divided into seven categories: awareness of wood culture; use characteristics of wood culture; preference and demand for wood culture; awareness of sub-fields of wood culture; awareness of the cultural resources of wood; trends of wood utilization; and wood-related living environment. Based on the survey results, the study analyzed four items: awareness of wood and cultural experience; awareness of the cultural resources of wood; wood-related living environment and trends of wood utilization; and preference and demand for wood culture. In this study, the public awareness of wood and cultural experiences, the first of four items, was analyzed using the survey results. Generally, wood and wood culture are viewed as materials and a cultural heritage, respectively. Moreover, wood is ecofriendly. However, no substantial difference was observed between the two perceptions. Forty-five percent of the respondents reported that using wood exerts a positive effect on the body and mind. However, such use also destroys forests. Additionally, the recognition of wood-related workers, such as engineers or skilled workers, was relatively low compared with educators, such as wood education experts. Moreover, less than 50% of the respondents answered that major projects related to wood culture are well-known, whereas 30% participated in wood education, such as woodworking experience, where the majority required hand tools. Furniture, wooden accessories, and wooden buildings were among the objects that individuals intended to make through the wood culture program. Approximately 23% of the respondents were aware about the wood culture experience center, while approximately 50% had visited it. The response rate to woodworking technology was 73%, where the highest response was found for wood education experts. To improve public awareness about wood, the importance of entertainment factors over educational factors should be considered in the experience of individuals. To provide opportunities to experience wood culture for more individuals, developing and actively promoting various contents, including entertainment elements, are necessary.

This study aimed to survey the impact of smartphone overuse on upper extremity pain, anxiety, depression, and interpersonal relationships among college students. Subjects completed a structured questionnaire consisting of the Smartphone Addiction Inventory, the Musculoskeletal Symptom Checklist, the State-Trait Anxiety Inventory, the Beck Depression Inventory-II, and the Relationship Change Scale from May to June 2012. We analyzed the survey data from 525 responses, excluding unreturned or incomplete surveys. Data were analyzed using the $x^2$ test and t-test to determine the differences in smartphone overuse and its impact on upper extremity pain, anxiety, depression, and interpersonal relationships between two groups: the overuse and normal use groups. Moreover, Pearson's correlation coefficient was used to examine the correlation between smartphone overuse and upper extremity pain, anxiety, depression, and interpersonal relationships. The results placed 62 people (11.8%) in the smartphone overuse group. The extent of smartphone overuse was more severe among female than male college students, and longer time spent using smartphones per day was directly related to smartphone overuse. The smartphone overuse group evidenced higher shoulder pain than the normal use group did, but no differences were found in other sites of the upper extremities. State anxiety, trait anxiety, and depression were higher in the smartphone overuse group than in the normal use group. Subjects with a higher extent of smartphone overuse experienced increased state-anxiety, trait-anxiety, and depression. Moreover, subjects with higher state-anxiety, trait-anxiety, and depression scores were more likely to have poor interpersonal relationships. Therefore, early screening for smartphone overuse should be evaluated, because it can be useful in developing addiction prevention programs to improve posture, stress coping, positive mental health, and effective interpersonal relationships.

Along with the development of telecommunication technology, educational role has been considerably changed and NEIS is introduced and operated for the digital educational administration. However, the function of NEIS is so limited when operated in each school. As a result, Korean government prepares the plan to install and operate a new School Affairs System by separating 3 areas from 27 areas of NEIS. School Affairs System has been used in schools since March, 2006. In this regard, this study attempts to analyze the current status and tasks of using the system in elementary schools. The result of the study shows that about 67% teachers use the system once or twice a day. Most of teachers answer that they get help from other teachers if they have any problem in operating the system. Many teachers affirmatively answer to the design and function of the system, and they are satisfied with the convenience and efficiency of the system. However, they feel difficulty to be familiar with the system sue to the frequent change. The importance of electronic certificate and personal information is well recognized and managed in terms of the security of the system. Facilities need to be well equipped, and information exchange system need to be developed to accept each school's request to improve the function of the system. In addition, applicable laws need to be arranged, clear guideline of educational administration agency and principal's strong intention are required to relieve teachers' work load.

The purpose of this study is to conduct survey on the DfS system for employees who perform construction-related tasks, analyze the results, and present improvement directions. The results of the survey showed that the system was gradually being settled, with about 82% and 93% positive results on the recognition and necessity of the system. In addition, the three highest response rates for the improvement of the system were first, improving the expertise of DfS-related performance personnel, second, improving the awareness of DfS-related actors, and third, reflecting the appropriate costs associated with DfS. For the realization of the above improvements, it was proposed to prepare a curriculum for improving the professionalism of the staff, to implement an incentive system for improvement of perception, and to prepare appropriate payment criteria for preparing reports available during the construction phase. In addition, the Korea Infrastructure Safety and Technology Corporation will need to perform its active role in order to become a system for preemptive management of risk factors for construction accidents from the design stage.

This study was performed to investigate whether aesthetic preference is related to the personality of an individual or not. Even though prior studies have reported that aesthetic preference for a certain style of art is associated with a personality factor, it is more important to focus on impressions and feelings about paintings than the style of art. The present study tried to examine how positive, negative, and neutral feelings about paintings are related to a personality factor, and that familiarity has an effect on aesthetic preference. After participants answered a Big-Five personality questionnaire, they then rated the preference for and familiarity about paintings which implied emotions. The results showed that individuals with higher scores of neuroticism preferred negative paintings. A preference for negative paintings is hard to explain, but this could be explained by results of this study. A hypothesis that familiar paintings would be more preferred is supported by the data. Aesthetic preference has both objectivity and the subjectivity. This study explained subjectivity through individual differences, and investigate art from a psychological point of view rather than conservative methods that sort paintings into art history.

For many years clustered heterogeneous web server architecture has been formed on the internet because the explosive internet services and the various quality of requests. The critical point in cluster environment is the mapping schemes of request to server. and recently this is the main issue of internet architecture. The topic of previous mapping methods is to assign equal loads to servers in cluster using the number of requests. But recent growth of various services makes it hard to depend on simple load balancing to satisfy appropriate latency. So mapping based on requested content to decrease response time and to increase cache hit rates on entire servers - so called “content-based” mapping is highly valuated on the internet recently. This paper proposes Prioritized Highest Random Weight mapping(PHRW mapping) that improves content-based mapping to properly fit in the heterogeneous environment. This mapping scheme that assigns requests to the servers with priority, is very effective on heterogeneous web server cluster, especially effective on decreasing latency of reactive data service which has limit on latency. This paper have proved through algorithm and simulation that proposed PHRW mapping show higher-performance by decrease in latency.

This single-blinded, nonequivalent control group pretest-posttest study was undertaken to evaluate the effectiveness of simulation education on clinical judgement, collaboration, communication skills, and perceived education practices and simulation design characteristics among student nurses in Korea. Participants were 47 students (19 in the experimental group and 28 in the control group) recruited by convenience sampling. The simulation based clinical reasoning education consisted of seven weekly, 120-minute high fidelity simulations. All participants completed the pretest and 7-week post measurements of a clinical judgment, collaboration, and communication skills with 4-week post measurement of collaboration, and participants in the experimental group provided a measurements of perceived education practices and simulation design characteristics. Data were analyzed using repeated measured ANOVA, and mixed linear model with SAS 9.2. Significant improvements were found in the experimental group for clinical judgment, collaboration, communication skill, and perceived education practices and simulation design characteristics. The study results show the impact of the perceived education practices and simulation design characteristics on facilitating the effectiveness of simulation education. The findings suggest a feasible and sound teaching method for student nurses and the need for further studies with a larger sample.

This study noted that elementary school students were unable to accurately comprehend the principles of moon phase changes and that teachers themselves lacked a full understanding of it as well. Therefore, this study classifies conception types through 161 5th grade respondents and suggests how to change students' conception types through the use of reconstructed teaching and learning materials (that have been developed in existing studies). It verified the changes in the learning achievement of 129 5th grade respondents and analyzed how to think about reconstructed teaching and learning materials through four teacher respondents and four 5th grade respondents from the same study. The results of this study are as follows: First, the conception types on moon phase changes were classified into C and W types. W types consisted of W1, W2, W3, W4, and W5 types. Students had difficulty in understanding the principles of a waxing crescent moon and first quarter phase changes. Second, the group taking classes, which implemented reconstructed teaching and learning materials, showed greater improvement in learning achievement posttest and long-term tests compared to those who have not. Finally, teachers and students reacted positively to the reconstructed teaching and learning materials as shown in exit survey results. In conclusion, it is suggested that teachers are better off utilizing reconstructed teaching and learning materials so that elementary school students may fully understand the principles of moon phase changes rather than just memorizing the results.
