  • Generally, aggregate may limit the strength of concrete, and aggregate with undesirable properties including strength, shape and grading etc. cannot produce good concrete. Also, the properties of aggregate greatly affect the durability and structural performance of concrete. Recently, it has increased the using of crushed aggregate for concrete due to the exhaustion of good natural aggregate. In case of Korea, the using ratio of crushed stone occupies about 97% of whole coarse aggregate, and ratio of crushed sand occupies about 18.3% of whole fine aggregate. This is an experimental study to compare and analyze the properties of crushed sand for concrete in capital region and concrete according to the replacement ratio of crushed sand to do suitable mix design and improve the concrete quality. According to results, it was found that nearly all the properties of crushed sand satisfied with the value recommended by KS.

  • This study validated the effect of Vaseline and the vegetable hormone-added medicine that can influence the formation of new calluses on the injured part, with the subjects of natural monument trees and large old trees. The medicines can help in the treatment of the pored or injured parts and promote the formation of new callus on natural monument trees and large old trees, which can help vigorous growth activities and prevent any secondary infection by pathogens at the same time. It turned out that the Vaseline that is used for the protection of cambiums after surgical operations on the trees did not have any significant effect on the formation of calluses. However, since it was found that new calluses formed rapidly when applying the medicine using a vegetable hormone, the medicine is highly recommended for use. If further studies should determine proper medicines for the trees according to the kinds of trees and if the medicine is applied in proper concentrations to the injured part for rapid formation of calluses on the trees when the trees undergo surgical operations, it then should be helpful in preventing the sound part(s) of the trees from decay caused by secondary infection and treatment of the injured part.

  • Purpose: This study was conducted to 1) find out the characteristic of smoke related characteristics of nurses. 2) find out the frequency of Smoking cessation intervention delivered by nurses. 3) compare the differences in mean scores of smoking cessation interventions by general characteristics. Method: The survey questionnaire was mailed out to nurses who were working at the randomly selected hospitals throughout the country from November 28, 2003 to February 15, 2004. Result: $0.6\%$ of nurses were current smokers $40.7\%$ of nurses have attended smoking cessation education. Nurses who were older, had masters degree, had oncology experience, higher position, participated in smoking cessation education, and had smoking related disease among family members were variables related to higher frequencies in delivering tobacco interventions. Conclusion: Although nurses are in an important position in delivering tobacco interventions and provide resources, their participation in consistent delivery of an intervention is less than desirable. To help nurses to participate in the assessment of tobacco use and interventions for cessation, the development of educational program is necessary.

  • Purpose: This descriptive study was conducted to project the number of nurse anesthetists needed in hospital settings, up to the year 2015. Method: Necessary data and information were collected from various funded reports, professional literature, web sites and personal visits to national and private institutions. The number of nurse anesthetists needed was projected after considering the total number of cases requiring anesthesia including deliveries, workload ratio for caesarean section to total number of deliveries, and percent of deliveries requiring and anesthesia. Result: The projected number of nurse anesthetists needed for hospital settings are as follows: 1. The number of registered anesthesia personnel in Korea in 2002 was 2,481 anesthesiologists and 543 nurse anesthetists but only 60% of anesthesiologists and 30% of nurse anesthetists (147) were actually practicing in the field of surgery. 2. By the year 2015, the total number of projected nurse anesthetists needed in hospital settings will be between 214 and 265. Conclusion: In order to match the supply to the need, the professional organizations should direct efforts towards enacting legislation. Educational systems should identify strategies to initiating an adequate number of nurse anesthetist programs at the master's level as well as standardizing curriculums across programs.

  • Purpose: This study was to develop Web-based multimedia content for Physical Examination and Health Assesment. Method: The multimedia content was developed based on Jung's teaching and learning structure plan model, using the following 5 processes: 1) Analysis Stage, 2) Planning Stage, 3) Storyboard Framing and Production Stage, 4) Program Operation Stage, and 5) Final Evaluation Stage. Results: The web based multimedia content consisted of an intro movie, main page and sub pages. On the main page, there were 6 menu bars that consisted of Announcement center, Information of professors, Lecture guide, Cyber lecture, Q&A, and Data centers, and a site map which introduced 15 week lectures. In the operation of web based multimedia content, HTML, JavaScript, Flash, and multimedia technology(Audio and Video) were utilized and the content consisted of text content, interactive content, animation, and audio & video. Consultation with the experts in context, computer engineering, and educational technology was utilized in the development of these processes. Conclusions: Web-based multimedia content is expected to offer individualized and tailored learning opportunities to maximize and facilitate the effectiveness of the teaching and learning process. Therefore, multimedia content should be utilized concurrently with the lecture in the Physical Examination and Health Assesment classes as a vital teaching aid to make up for the weakness of the face-to- face teaching-learning method.

  • Domestic timber comsumption has increased dramatically in the past few decades in this country. In addition, there is increasing demand for recreational opportunities in the forest areas and concern for watershed management and soil conservation. However, it is difficult to satisfy these demands for forest resources because many of woodland owerners who make such demands possible move from mountain villages to modern cities. Therefore, whether or not it is in the public interest to invest in rurbanization is a central policy question. This is a case study which deals with mountain village problems for making forest resources.

  • Purpose: The purpose of this study was to evaluate the effectiveness of spiritual intervention studies by examining biological, psychological, and spiritual outcomes. Methods: From electronic databases 2522 studies were retrieved, of which 21 studies met the inclusion criteria. These studies had 1411 participants. Two authors independently extracted data from the selected studies and assessed the methodological quality. The data were analyzed using the RevMan 5.1 program of the Cochrane library. Results: Overall effect size of spiritual intervention on spiritual and psychological (depression and anxiety) outcomes were moderate (d= -0.65 to d= -0.76, p<.001). The effects on biological outcomes (pain and functional status) ranged from -0.51 to -0.39, respectively. No publication bias was detected as evaluated by a funnel plot. Spiritual intervention had a moderate effect on psychological and spiritual outcomes and a smaller effect on biological outcomes. Conclusion: The results of this study suggest that spiritual intervention can relieve depression and anxiety. Further randomized controlled trials studies are needed to evaluate the effects of spiritual intervention on biological outcomes.
