  • Shipboard equipment in naval ships should be designed to be safe under the shock load. Very high stress due to the shock load can be effectively reduced by the resilient mounts considering the mount capacity and dynamic characteristics. An optimum arrangement of resilient mount installed to absorb the shock energy is addressed to assess the safety of ship structure and shipboard equipment subjected to the shock load. Structural responses are analyzed for both frame structure supporting the shipboard equipment subject to the shock load with and without the resilient mounts. The shock absorbability of the resilient mount is evaluated by the results of structural response analysis; meanwhile, several types of shock analyses considering the arrangement of resilient mounts are carried out and the shock responses are compared to verify the effect of the arrangement. Thereafter, optimum arrangements are obtained by means of Genetic algorithm (GA) considering the different capacities of resilient mount. Stress, deformation and dynamic feature at the frame structure supporting the shipboard equipment under the shock load are also discussed in order to meet the capacity of resilient mount.

  • Energy saving has been main concern, thus government supporting policies which are based on Fundamentals of Low-carbon Green Growth Act', 'Green Building Support Act, have been prepared in Korea. The objective of this study is to estimate energy conservation effectiveness and economic advantage assuming that lighting equipments and heat source equipments would be retrofitted. Office building, which has total floor area of $30,000m^2$, was a subject of this study. From the estimations, electric rate will be decreased by 62,886,000 won per year due to lighting equipments retrofit, and gas rate will be decreased 11,141,000 won or 17,332,000 won per year due to heat source equipments retrofit (in case of COP 1.2 or 1.5). Payback period of each case that are calculated by energy saving cost and retrofit cost are estimated 27.9 year, 38.6 year and 29.2 year, thus economic supporting policies is necessary for effective energy saving in buildings. Meanwhile payback period of heat source equipment for new building is estimated 6.1 year and 8.3 year.

  • Background: The CKCUES test evaluates the functional performance of the shoulder joint. The CKCUES test scores CKC exercises of the upper limbs to examine shoulder stability. Although the CKCUES test provides quantitative data on functional ability and performance, no study has determined the relationship between CKCUES scores and SA and TB muscle strength. Objects: The objective of this study is to determine the relationship between the CKCUES test scores and the strength of the SA and TB muscles in the CKCUES and unilateral CKCUES tests. Methods: Sixty-six healthy male volunteers participated in the study. A Smart KEMA strength sensor measured SA and TB muscle strength. Two parallel lines on the floor indicated the initial hand placement to start CKCUES tests. For 15 seconds, the subject raises one hand and reaches over to touch the supporting hand, then returns to the starting position. Results: The correlation between the CKCUES test scores and the strength of the SA was strong (r = 0.650, p < 0.001), and the TB was moderate (r = 0.438, p < 0.001). The correlation between the unilateral CKCUES test and the strength of the SA of the supporting side was strong (r = 0.605, p < 0.001), and swing side was strong (r = 0.681, p < 0.001). The correlation between the unilateral CKCUES test and the strength of the TB of the supporting side was moderate (r = 0.409, p < 0.001), and swing side was moderate (r = 0.482, p < 0.001). Conclusion: Our study showed that the CKCUES test had a strong association with isometric strength of SA and moderate association with that of TB. These findings suggest that the CKCUES test can evaluate the function of the SA. Moreover, the unilateral CKCUES test can evaluate unilateral shoulder function.

  • 현재의 순음청력검사 시스템은 한 명의 청각사가 한 명의 피검자를 검사하는 일대일 검사방법이기 때문에 검사에 고비용이 수반되고 피검자가 많을 경우 검사 대기시간이 길어지는 단점이 있다. 이 같은 단점을 해결하기 위하여 한 명의 청각사가 여러 피검자들의 청력검사를 동시에 진행할 수 있는 클라이언트/서버 모델의 PC 기반 청력검사 시스템을 개발하였다. 본 모델에서는 다수의 피검자 PC들이 LAN을 통해 청각사의 PC에 연결되는 구조를 가지며, 각각의 피검자들의 검사 진행상황이 실시간으로 청각사의 화면에 표시된다. 또 청각사는 필요시에 현재 진행 중인 특정 피검자의 검사 과정을 마치 일대일 검사 방법처럼 조정하는 것이 가능하다.

  • The present paper aims to examine the Influences of on line word of mouth(WOM) information valence and information contents to the information searcher. Specially, to examine the interaction effect it's two variables. For that purpose, we categorize WOM information valence into two subcategories; positive and negative, and WOM content into two subcategories; objective evaluation and subjective evaluation. We conducted experimentation design 2*2 and subjects are asked to their attitude and purchase intention after they are exposed each of four different types of WOM information. The result can be summarized as follow; First, the negative WOM has stronger effect on consumer's attitude and purchase intention than positive. Second, factual WOM has stronger effect on consumer's attitude and purchase intention than subject. Finally, when consumer face negative WOM, subjective WOM has more effect on consumer's attitude and purchase intention than factual. On the contrary, when consumer face positive WOM, factual WOM has more effect on consumer's attitude and purchase intention than subject. In conclusion, the korean Foreign Trade Act and other relative acts should be revised, and both educational services and health services should be contained within the definition of "the international trade" for the governmental benefits of supporting the services exportation.

  • The purpose of this study is first, to analyse the present nursing education and the curriculum in Korea in view of the changes and the new tendency of nursing education and second, to compare our curriculum with that of America, where nursing activities are actively earring on and, third, to try to find out what we should reconsider and improve in our nursing education. The object of this study is the educational program and the curriculum from 1973 to 1976 by selecting each five from colleges and department of nursing in Korea and America. The results of the study were as fellows : . 1. The aim of nursing education puts impassion the role of leader, knowledge and technology of nursing, welfare of society and service of community in both the America and Korea. In Korea nursing is mainly restricted to the treatment of diseases, while in the America the items of the aim of nursing are mainly extended to the capacity for Self- realization of nurse, in Korea they are restricted to the treatment of diseases. 2. In Korea the rate of credit of the curriculum of nursing education is the highest in professional education, next in general education, next in supporting science and educational subject, while in America the rate of the credit is the highest in general education, next professional education and then supporting Science and educational subject isn′t included in the curriculum. 3. In both Korea and America the role of the animal credit allotment in general education, is the highest in the first year and the rate in supporting science is the highest in the second year. In Korea professional subjects are concentrated in the third year while in America there is a tendency that they are increasing in number in the grade order. 4. There is a tendency that the rate of the credit allotment of the main professional subjects in curriculum is higher in Korea than in America : that is, in Korea the rate of the allotment of the credit is the highest in medical - surgical nursing, next maternal - child nursing, next community - health nursing and the psychiatric nursing and there in a great difference in the rate of the allotment of each credit. While in America the rate of the allotment of the credit is the highest in community - health nursing, next in medical- surgical nursing, next in maternal - child nursing, and then in psychiatric nursing and there is little difference in the rate of tile allotment of each credit. 5. From general education, supporting science and professional education, they have considered the continuity and sequence in the structure of nursing curriculum of Korea and America. While in Korea we have partly made integration in tile content of the subjects. Most of the school in America, they have made integration in the content of subjects especially in all subjects, but in Korea we haven't made it in all subjects. 6. In the system and form of nursing education Problem solving method, Dialectical method and operational method are introduced in some America schools and in others there is a tendency that the whole nursing education has the system based on Preventive frame - work or Health -illness frame work ; while only one college has an attempt for Health - Illness continue in Korea. 7. In Korea nursing education, as the importance of health- nursing and team nursing, the aim which is also comparatively emphasized is about health management and service of collective community. The subject pertaining to the aim is the studies of community health nursing, which are more in number in America. 8. When we consider the association between the social, general aims ?f the nursing education and the formation of the curriculum in Korean nursing school the courses of study concerning "the role of leadership and cooperative personal relation": "nursing care for the group": dynamic nursing care": and "the system of the public health nursing associated with the understanding of the regional community" are insufficient as compared with those of America. Especially, the lack of the behavioral science including the nursing care connected with the care for the group, the basic science on the clinical and developmental psychology, anthropology in known to be a prominent issue.
