The new course distances of a ship are one of the important factors of the safety handling as the indices to indicate directly her abilities of course alteration. Recently, International Maritime Organization (IMO) exhorts that all vessels should use maneuvering booklets in which are drawn the curves of new course distances obtained from the test of measuring them and noted other maneuvering performance standard in various navigation conditions. This paper describes the method to calculate many new course distances for many rudder angles by turning circle test without observation or using other calculating methods. The main results are as follows: 1) The mean difference of the distances between two new course distances by the turning circle test and heading test of the experimental ship was about 7.7% vaules of the ones by the heading test. when her altering angles were $48^{\circ}$, $63^{\circ}$and $70^{\circ}$, using the rudder angle of $35^{\circ}$ . These new course distances were therefore found to be small in difference of those. 2) The mean difference of the distance between two new course distances by the turning circle test and the maneuvering indices of the experimental ship was about 4.5% values of the ones by the maneuvering indices, when her altering angles were $48^{\circ}$, $63^{\circ}$and $70^{\circ}$, using the rudder angle of $35^{\circ}$, these new course distances were therefore found to be small in difference of those. 3) The mean difference of the distance between two new course distances by the turning circle test and the observation of the experimental ship was about 6.1% values of the ones by the observation, when her altering angles were $48^{\circ}$, $63^{\circ}$and $70^{\circ}$, using the rudder angle of $35^{\circ}$. These new course distances were therefore found to be small in difference of those. 4) It is confirmed that many new course distances for many angles can be calculated easily by using the method of ship's simple turning circle test, without observation or using the maneuvering indices and heading test method. 5) It is considered to be helpful for the safety of ship handling to draw curves of new course distances by turning circle test and $\phi_4$ - $\phi_2 by heading test, and utilize them at sea.

The new course distances of a ship are considered to be the indices to indicate directly her abilities of course altercation. Generally, they have long been calculated by using the maneuvering indices obtained from her Z test. However, at sea actually the maneuvering indices can not sometimes be obtained according to ship's condition or circumstances and the new course distances can not be calculated. To find out other method to calculate the new course distances, in this paper the author analyzed them from a viewpoint of ship motion, and worked out a numerical formula to calculate them easily, using the data of ship's heading test. In order to check whether the presented method is applicable to actual ships or not, the experiment by them were also performed. The results obtained are summarized as follow: 1. The mean difference of the distance between two new course distances by the heading test and the maneuvering indices of the experimental ship was about 0.98% values of the ones by the maneuvering indices, when her heading were 10。, 20。 and 30。, using the rudder angle of 15。. These new course distances were therefore found to be almost same in values of the distance. 2. The mean difference of the distance between two new course distances by the heading test and the observation of experimental ship was about 1.16% values of the ones by the observation, when her headings were 10。, 20。 and 30。, using the rudder angle of 15。. These new course distances were therefore found to be almost same in values of the distance. 3. It is confirmed that the new course distances can be calculated easily by using the method of ship's simple heading test, without the observation or using the maneuvering indices. 4. It is considered to be helpful for the safety of shiphanding to draw curves of new course distances by ship's heading test and utilize them at sea.

This study reviews an English enhancement course implemented for medical and nursing college students of 2011 to improve their standardized English test scores. A total of 117 first-year students underwent the pre-test and the post-TOEIC in November 2011. After the pre-test, lectures on listening enhancement strategies and problem solving tactics on reading comprehension were supplemented with 4 times of enhancement-tests. Their pre- and post-TOEIC results were compared to see if such enhancement strategies were effective to improve their TOEIC scores. It was further to investigate, through survey questionnaires, how the subjects felt about a number of pre-test-type TOEIC exercise with what-to-listen and how-to-infer listening strategies and pattern-drill practices for reading comprehension. It was found that the scores of listening comprehension improved significantly for both major students whereas reading scores showed slight decrease among nursing majors. It is concluded that administering numerous pre-test-type-TOEIC exercise is effective for students to improve their listening scores supplemented with listening strategies Also, students' response showed positive toward the enhancement course.

LTV(Light Tactical Vehicle) operating in our military requires higher levels of performance and durability to withstand harsher conditions than general vehicles, as they must travel on both rough-train and off-road as well as on public roads. Recently, LTV development is demanded a variety of test evaluations in order to satisfy ROC (Required Operational Capability) by the military requirement. However, there is no informations of driving test course for satisfying the durability performance of Korean tactical vehicle. Therefore, this study aims to provide basic data to establish reliable drive test conditions by analyzing the main maneuvering test site at the domestic and foreign country in order to select the representative drive course. These studies will provide a more scientific and systematic evaluation solution for the development of tactical vehicles, and can be effectively used to establish a certified system for military vehicle test evaluation in the future

This Study explores and describes the present status and effects of Korean social work ethic course , reflecting increasing concerns about social worker's ethics. Using the member list of the Council of Korean Social Welfare Education, this study first examines the extent to which the ethic course is established and how the course is managed. Then, for the purpose of investigating the practical effects of the enrollment in the ethic course, using the test scores designed to measure the students' sensitivity to ethical issues, this study compared test scores between students who attended the course and those who did not. This study also compared pre-post test scores of students who attended the course. The results show that enrollment in the course contributes to significant changes in the students' ethical sensitivities, in spite of social work education system that does not very yet empathize the ethics curriculum very strongly. Further, enrollment in the ethic course is proved to be a more powerful factor to ethical sensitivity than any other demographic or education related factors. These findings suggest a stronger emphasis abd serious consideration of the course, as well as more efforts to bring up professionals and invest in research in the field of social work ethic education.
