The success and failure of any project depends upon many factors, the Project Manager is considered to be the key contributor to the success of any project, as well as a guide to the team members to achieve the client satisfaction (Cost, Time and Quality). Therefore the main aim of this paper is to provide a practical approach for understanding the importance of the Project Manager and his effectiveness to the success of the construction projects. In addition, the Project Manager's roles, responsibilities and duties have direct impact to the success of the construction projects. In order to identify the thoughts and opinion of the construction industry on this particular assertion, a quantitative study was carried out within the UK construction industry. The result of the study shows that there is an extremely strong correlation between the Project Manager and the success of the construction projects. In construction projects the Project Manager is considered to be one of the most important people who can lead and drive the projects in the right direction and conclude construction projects successfully. Moreover, these can play the most important role regarding the improvement of the organization's performance, the organization's profitability and the client's satisfaction. The research confirmed that the Project Manager is a very essential element to the success of the construction project and have an impact at every stage of the construction project. So it concluded that selection of a Project Manager should be carefully done with regard to experience, knowledge, power/authority and good understanding to the kind of the project.

Purpose: This cross-sectional study was to find out smoking condition, smoking related knowledge and attitudes of white color workers to provide baseline data which were to develope smoking cessation programs. Methods: The subjects were 303 workers in G-city. Data were collected from July 1st to Aug. 31st 2003 by self-reported questionnaire. Data were analyzed by descriptive statistics, t-test, ANOVA, and Duncan's multiple comparison test, using SAS-pc 8.0 version. Results: Average age of the laborers was 32.3 years, and 50.7% of male were smoking currently, and 2.4% of female were so. Starting age of smokers was average 20.1 and smoking period was average 12.4 years. Majority of smokers smoked more than one pack of cigarettes in a day. Average points of nicotine dependency was 3.9 out of 10 and 12.5% were more than 7. Those who wanted to 'quit smoking very soon' and 'decided to quit smoking right now' were 29.1%. But those who got any helps and advices from professional experts in smoking cessation were 6.4%. 83.5% of the smokers had tried to quit smoking but failed due to their stress(44.6%), lack of will(36.6%) etc. Laborers knowledge related smoking score were average 11points out of 15, and attitudes were average 75.7points out of 125. Smokers showed significantly low knowledge(p=.012), and more allowing attitudes(p=.001). Conclusions: The smoking cessation programs for the workers should consist of stress management skills, and strengthened willingness. And should be run the program for those who want to 'quit smoking very soon' and 'decided to quit smoking right now' first of all.

The purpose of this study was to elucidate the effects of spiritual nursing intervention on pain and anxiety of the hospice patients. This study was devised with a quasi-experimental design using non-equivalent contrast group non-synchronized design. The data were collected during the period from July 10 to September 25 in 2000 at the general hospital in CheonJu city. The subjects were sixty-seven patients who referred the hospice service. They were assigned to two groups, 36 members of the experimental group and 30 members of the contrast group. They also did not any complication, were alert enough tobe interviewed and agree willingly to participate in this study. The tools used were Yoon's Korean Version of Brief Pain Inventory and Spielberger's State Anxiety Scale. The spiritual care intervention was carried out through Hymn, Scripture, Prayer, the therapeutic use of self over a period of three weeks. Data were analyzed by mean, standard deviation, $x^2$-test, t-test, paired t-test and Pearson's Correlation Coefficients. The results of this study were as follows: 1.The examination of the same quality showed that there were not significant differences in the general characters, disease and therapeutic characters, religional characters between the experimental group and the contrast group. 2.After the spiritual nursing intervention pain scores of the experimental group were remarkably lower than those of the contrast group(right now pain: t=-2.634, p=0.012). 3.Decreasing rate in the pain scores of the experimental group were remarkably lower than those of the contrast group(right now pain: t=5.017, p=0.000). 4. After the spiritual nursing intervention state anxiety of the experimental group were remarkably lower than those of the contrast group(t=-5.987, p=0.000). 5. A positive correlation was found between reported pain and depression following the spiritual nursing intervention. In conclusion, the hospice patients who were offered spiritual care became lower than those who were not offered spiritual care and confirmed to decrease pain. According to these results, spiritual nursing intervention can be regarded as an effective nursing intervention that relieved pain and anxiety of the hospice patients.

The purpose of this study was to investigate the effect on the activity of the upper trapezius and erector spinae according to the length difference of the backpack using electromyogram (EMG). We also conducted a study comparing the center of pressure (COP) and weight distribution before and after using Wii® balance board. Thirty individuals were randomly assigned to the experimental group (n=14) wearing a backpack with a short right strap length and a control group (n=16) wearing a backpack with the same strap length. Data were collected by dividing into groups, carring a 15% weight backpack and walking for 20 minutes on a treadmill. As a result of analyzing the EMG data, there was no significant change in the upper extremity muscle activity of the control group, but it was significantly decreased in the right upper trapezius activity of the experimental group (p<0.05). In addition, there was a significant change of COP in the experimental group (p<0.05), but there was no significant difference of the weight distribution in both groups. Recognizing mechanical changes in the body that may occur due to the asymmetry of the strap length is thought to be helpful for systematic ergonomic intervention according to changes in the external environment in the future.

A GPS-drifter was newly designed to observe the sea surface skin current and to estimate the direct wind effect on the sea surface. After conducting a test to establish and verify the accuracy of the GPS itself in the laboratory, in-situ experimental campaigns at Saemangeum in Gunsan city and Haeundae in Busan city, Korea, were carried out to ascertain the drifter track and to estimate the velocity data set on Oct. 3, 15, 23, 27 and Nov. 25, 2011. The current meters, RCM9 and ADCP, were moored together to remove the background current field, and the wind data were obtained from several marine stations such as towers and buoys in these areas. The drifter-observed velocity show good agreement with the flow obtained by the HF radar in the Saemangeum area. The direction of the wind-driven current extracted from the drifter-observed velocity was completely deflected to the right, however the degree of the angle was different according to the drift types. The average speed of the wind-driven current matched with 2.19~2.81% of the wind speed and the deflection angle was about $8.0{\sim}10.9^{\circ}$ without adjustment for the land-sea effect, and about 2.19~2.84% and $4.1{\sim}6.0^{\circ}$ with the adjustment for the land-sea effect.
