  • The Equipment Expenses section of the Poom-Saem that is used for Construction Cost Estimation of public sectors in Korea has been rarely revised, and so does not reflect changes of Construction Equipment technology and construction methods, since it was established based on data from Japan and the U.S in the early 1960s. In order to make reasonable estimation of equipment expenses for a bulldozer and a loader, the domestic and overseas documentary records were investigated. Further, 16 construction sites were visited, and 20 Construction Equipment leasing services were surveyed. The optimum level of each item which consists of equipment costs was revealed based on the result of the analysis on the figures of equipment costs calculation from the Poom-Saem and the collected data. The research will be the foundation for applying the rapid development of Construction Equipment and technology to the appropriate cost estimations and the ground work of related studies.

  • The study was aimed to develop men's working pants patterns through the computerized 3-D virtual clothing simulation system and to verify the effects of the 3-D simulated outfit by comparing it to the images of the actual outfits. The average body measurements of South Korean men aged between 30 and 39 used for the simulation in order to generate a 3-D virtual model and to realize outfits of men's working pants for the workers in the heavy industry in South Korea. And also the preliminary questionnaire survey results on certain aspects of the working pants such as type, detailed design preference and discomforting parts were taken into consideration. Both the simulated and real images of the developed working pants were compared in terms of the ease amount according to parts of the working pants, the position of seam lines, the appearance of darts and pleats, and the effects of the fabric surface according to expertise panels' subjective 5-point scale evaluation. The results throughout the study were (1) the basic working pants item worn by subject workers were the straight one pleated pants. The most discomforting parts of the working pants were in the order of body rise, thigh, hip, waist, pants hems and knee girth. (2) the drafting factors of pants patterns differed by the men's body features, which was related to the allocation of suppression amounts between waist and hip girths into darts and hip curve amounts on the waist line level of the pants. (3) the similarity of the virtually simulated and real images of men's working pants resulted in an average of 4.5 to the ease of appearance, 4.6 to the seam lines, 4.1 to the fabric surface effects in a 5-point scale, which means that the two were highly alike.

  • Massage therapy is a traditional, alternative and nonphamacological means of promoting rest and relaxation. However, nursing intervention by massage for middle-aged women is rarely practiced by nurses. The purpose of this research was to examine the effects of the hand and arm massage as an independent nursing intervention tool for middle- aged women. The data used in this research were collected from forty-nine subjects using a nonequivalent control group non- synchronized design. Twenty-four persons for the experimental group and Twenty-five persons for the control group were selected from D city and C city from July 1997 to September 2000. Subjects' ages were between forty and fifty-six years old with mean the age of 45.6. Hand and arm massage developed by Cayce and Reilly was applied to the experimental group for a session of 15 minutes two or three times a week for four weeks. The instruments used for the measurement of the subjects' stress, anxiety, depression and the middle-life crisis were Langners's 22-item Self-rating Depression Scale, and Kim's Middle Life Crisis Scale(1988). These psychological factors were measured before and after the implementation of hand and arm massage. The data were analyzed with mean$\pm$s.d, percent, t-test, and a paired t-test. The results were summarized as follows; 1. Before the treatment, there were no significant differences between the two groups. 2. After the treatment, there were significant differences in the stress and the occurrence of mid life crisis between the two groups. The findings suggest that the use of the life crisis. Therefore, it is recommended that hand and arm massage be used as an independent nursing intervention tool for middle-aged women. For further research, is needed replication of this concept of research with different subjects in a larger population. Also, it is recommended to investigate the effects of massage with aroma therapy for the berefit of decreasing womens' stress level further.

  • Background: The scientific evidence relating to the burden of oral diseases attributable to tobacco use has been reviewed and the need for a well-structured dental teaching program concentrating on oral cancer education and tobacco cessation interventions has been emphasized. The aim of our study was to evaluate the awareness of oral cancer and perception of tobacco use cessation counseling among dental students at all study levels in India, Saudi Arabia, the United Arab Emirates, and Yemen. Materials and Methods: A structured, pre-tested, self-administered 15-item questionnaire was used to conduct a cross-sectional survey. Data analyses including percentages, frequency distributions and tests of chi-square were generated. Results: A total of 621 (97.6%) Indian, 493 (96.5%) Saudi, 194 (96.5%) Yemeni and 187 (98.4%) United Arab Emirates respondents recognized the association between oral cancer and cigarette smoking. Although more than 96% of the students surveyed recognized the association between oral cancer and cigarette smoking and about 55% reported cigarette smoking as one of the etiological factors of oral cancer, more than 66% of students who reported cigarette smoking as an etiological factor of oral cancer disagreed/strongly disagreed with all the statements concerning tobacco use cessation. Conclusions: A higher level of oral cancer awareness did not have a positive impact on the perception of tobacco use cessation counseling among the sample surveyed.

  • In order to ensure that the 2015 revised curriculum is successfully settled at the field of school, there are 68 national SW schools operated by 2015 and 2016 at national level, and an inspection tool was developed to measure the effectiveness of SW education. The purpose of this study is to present the direction of the computing thinking inspection tool which can verify the effectiveness of the curriculum from 2018 through the analysis of the previously developed computing thinking inspection tool. As a result of the analysis, the validity of the ability factors to measure the problem solving process based on computing thinking was not enough. In the analysis of the item characteristics, the degree of discrimination was good, but difficulty was not enough to accurately measure the competence of students because of the high percentage of easy questions. Based on the results, this study suggested the development of the items considering the problem solving process based on the computing thinking, the application of the students' empirical knowledge, and the constitution that can confirm the flow of the thinking power with materials in the real life.

  • The purpose of this study is to provide basic information for the development of pants patterns with a high level of fit and comfort through calculating surface variations of lower body parts by movement, grouping them into factors, and analyzing how their surface variations link to one another. The achieved results will help determine essential elements for constructing pants patterns, such as key measurements of lower body parts, the amount of ease values and selection of fabrics, which should be taken into consideration for allowing better movement in clothing. The study required lower body 3D scanning of women for analysis, and 13 women between the ages of 20-24 participated in the scanning, which was done by using Artec Eva 3D scanner. Their scanned data were digitalized and converted to measure the values of their lower body surface length and girth in pre-determined positions such as walking, stair climbing and sitting on a chair. These measurements have been statistically analyzed through SPSS 21.0 to obtain the average amounts and rates of extension for each of the measurement item. Some of the highlighted study results are as follows: The surface length and girth measurements were grouped into 4 factors based on their average extension rates. The results from correlation analysis between measurement items within each factor demonstrated that common items linked to all the changes in the values of other items in the three movements. But in most cases, items were not always correlated with each other for different movements. The results also showed that there were correlations between girth measurements, length measurements, and girth and length measurements. Therefore, key measurements for daily pants should be determined within reasonable estimations between relevant measurement items, while the measurements for work pants, which often withstand certain postures or repetitive movements, may require measurement items that are appro priate for, and closely related to, certain movements or tasks.
