Purpose: Missing cervical pathology after injury may lead to disability and influence long-term survival. Controversies continue to evolve concerning the initial screening methods used to predict cervical spine injury. Through a retrospective chart review, we attempted to analyze and propose factors predictive of cervical trauma. Methods: Of all the patients who had visited the Emergency Department of Korea University, from January 2009 to December 2009, a retrospective review of the clinical records of the 217 patients who had undergone cervical spine computed tomography was done. We investigated whether we could predict the need for cervical spine computed tomography shortly after presentation in trauma patients by comparing the group with fractures and group without fractures and by finding risk factors showing significant differences between the two groups that might be used as guides in decision making. Results: Of the 217 subjects who underwent cervical spine computed tomography scans, 33 were identified with fractures of the cervical spine while 184 were not. The most common mechanisms of trauma, in order, for those with fractures were falls, followed by traffic accidents. We found that the injury severity score, multiple injuries, a high-energy injury mechanism, neurologic deficit, and pain and tenderness of the cervical spine showed statistically significant differences between the two groups. Conclusion: Fractures of the cervical spine that are not observed with simple radiography occur with a relatively high frequency in trauma patients. Consideration should be given to the risk factors for cervical spine fracture, and if pertinent, cervical spine computed tomography should be performed with speed for early diagnosis of cervical spine fractures.

이 연구의 목적은 융합인재교육(STEAM)의 현장적용에 대한 초등 교사들의 인식을 조사하기 위한 것이다. 연구대상은 초등 교사 80명이었다. 이 연구의 결과는 다음과 같다. 첫째, 초등 교사들이 STEAM 교육의 의미와 목적에 대해 자세히 알고 있음에도 불구하고 실질적인 교육지도방법에 대해서는 중립적인 입장을 취하는 경우가 많았다. 또한 교육 모임에 대해서도 대부분 부정적인 입장을 가지고 있었다. 둘째, 수업 준비와 수업 시간에 STEAM 교육 관련 교재를 사용하는 초등 교사는 매우 적었다. 또한 STEAM적접근을 통해 개념을 가르친다는 교사 역시 극히 적었다. 개발되어 있는 모듈을 사용하였다는 응답 역시 적었으나 모듈 개발에 대한 요구는 매우 높은 수준으로 나타난 것으로 보아 지속적인 STEAM 교육의 정착을 위해서는 교사가 사용하기 쉬운 적절한 모듈이 개발되어야 할 것으로 사료된다. 셋째, 실제 수업 현장에서 STEAM과 관련된 교육 주제, 교육 활동, 평가를 적용하는 교사는 극히 드문 수에 해당하였다. 넷째, 현장 적용 한 후의 긍정적인 측면의 변화에 대해서도 대부분의 초등 교사들은 향상된 측면에 대해 잘 인지하지 못한다는 응답과 같은 부정적인 견해를 가지고 있었으며, 적용 후의 문제점에 대해서는 학생들이 STEAM 수업을 통해 얻은 결과와 교과서 내용을 연결하지 못하기 때문에 교육과정을 재구성하고, 쉽게 활용 가능한 프로그램을 개발하고 보급해야 한다는 문제점들을 많이 제시하였다. 이처럼 초등 교사들이 융합인재교육의 현장적용에 대해 가지고 있는 인식은 매우 부정적이었다. 융합인재교육이 초등에서 성공적으로 적용되기 위해서는 초등 교사들의 융합인재교육에 대한 인식을 긍정적인 방향으로 전환하고, 교사의 요구가 반영된 프로그램과 다양한 교수 학습 자료의 개발과 보급이 절실하다.

The purpose of this study was to examine the effect of eating with family or alone on the self-rated mental or physical health and then work out strategies of making people recognize the importance of eating with family and its practice. Study subjects were 610 primary school 5th- and 6th-grade students in Daejeon Area. A questionnaire survey was carried out. 57.9% of students had working mothers. The frequency of meal in a day was $2.90{\pm}0.42$ and this frequency was lower in students who had working mothers (p < 0.05). The frequency of skipping breakfast (times/week) was $1.02{\pm}1.77$. The frequencies of eating alone (times/week) were $1.04{\pm}1.65$ for breakfast and $0.97{\pm}1.52$ for dinner. Also, the frequency of eating alone for dinner was higher in students who had working mothers (p < 0.001). When the frequency of eating alone for breakfast or dinner was higher, the frequencies of skipping breakfast and dinner were also higher (for all, p <0.01). When the frequency of eating alone for breakfast or dinner was higher, the self-rated positive mental health were lower (p < 0.05 and p < 0.01 respectively) and the self-rated negative mental health (for dinner, p < 0.05) and the self-rated negative physical health was higher (p < 0.05 and p < 0.01 respectively), thus presenting negative health. The frequencies of eating with family (times/week) were $3.37{\pm}2.50$ for breakfast and $4.14{\pm}2.19$ for dinner. Also, the frequency of eating with family for dinner was lower in students who had working mothers (p < 0.01). When the frequency of eating with family for breakfast was higher, the frequency of skipping breakfast was lower (p < 0.01). When the frequency of eating with family for dinner was higher, the frequency of skipping dinner was lower (p <0.01). In addition, when the frequency of eating with family for breakfast or dinner was higher, the self-rated positive mental health were higher (for both, p <0.01) and the self-rated negative mental health was lower (for breakfast, p < 0.01) and self-rated negative physical health were lower (for both, p <0.01), thus presenting positive health. Therefore, in order to maintain positive health, it is necessary to recognize the importance of eating with family at home and educate people to carry out a systematic and continuous dietary life, thus increasing eating with family and reducing eating alone and skipping a meal.

Purpose: This study was conducted to serve as a basis for strengthening policy support and R&D to improve the domestic and international competitiveness of domestic agricultural machinery. Levels of satisfaction among farmers and service engineers were analyzed regarding the current quality of agricultural machinery and the primary consumers' propensity for replacement purchases. Methods: A survey was carried out targeting farmers in over 150 townships and 300 villages in South Korea who collectively used 711 tractors, 286 rice transplanters, and 221 combine harvesters. Furthermore, agricultural machinery service engineers from 20 different after-services were surveyed regarding the quality of main components in domestic agricultural machinery versus those in imported agricultural machinery. Results: The farmers' overall quality satisfaction ratings for tractors, rice transplanters, and combine harvesters ranged from 57.1% to 62.6% in consideration of operating performance, failure rate, and durability. Compared with imports, satisfaction ratings for domestic agricultural machinery were 19.1%p to 38.1%p lower for quality. Regarding engines, transmissions, hydraulics, planters, reapers, threshers, and electrical components, only 5.3% to 25.0% of service engineers indicated that domestic agricultural machinery was higher in quality compared with imports. By contrast, 33.3% to 78.9% of those surveyed indicated that domestic components were lower in quality compared with imports. Intent to purchase replacement agricultural machinery at the end of their respective products' lifecycles was indicated that they planned to purchase imported tractors, rice transplanters, and combine harvesters comprised 25.2%, 46.9%, and 43.9%, respectively. This clearly shows that a very high percentage of farmers were satisfied, particularly for transplanters and combine harvesters. Conclusions: The level of desire for purchasing imported agricultural machinery was very high among those who expressed intent to purchase replacement machinery. Therefore, strong policy support and R&D for domestic agricultural machinery is critical for improving competitiveness on the domestic and foreign markets.

Purpose - The Northeast Asian Logistic Hub strategy was established to create a national competitive advantage in northeast Asia. Countries in this region are competing fiercely to become the central base distribution port as the volume of container shipping continues to increase due to the northeast Asian (especially Chinese) economic growth. The primary method by which shippers are improving their customer service and distribution is enhancing profits by minimizing call ports on the key route through strategic affiliations and the use of large vessels. Each nation is planning large-scale investments in the construction of sea ports that can accommodate large vessels. This paper proposes ways by which the logistical strategies of domestic corporations can keep pace with changes in government policy concerning the Northeast Asian Business Hub policy. It examines the logistics system in the Northeast Asian region, analyzes the government's Northeast Asian Business Hub policy, and suggests logistical strategies for domestic corporations through an analysis based on a questionnaire designed to grasp domestic firms' needs and goals. Research design, data and methodology - The purpose of this study is to determine how shipping companies establish partnerships with third-party logistics providers and draws out the implications of the results. The survey methods used were personal interviews and questionnaires distributed to a sample population through e-mail, fax, mail, and telephone. A total of 600 questionnaires were distributed, of which 165 were returned. Among these, ten were excluded due to insufficient content; ultimately, 155 were used for the sample. The statistical data collection process was analyzed through data coating and a statistical package program. Results - This study argues that greater flexibility in policies, administration, and systems will be needed to significantly improve established business practices. In this dissertation, we primarily identify that in order to become a center of northeast Asian logistics, Korea must adopt a new paradigm and abandon the existing systems that are based on the economic and social systems that have stemmed from bureaucracy, inflexibility, chauvinism, and equalitarianism. Flexible policies, administration, and systems will be necessary to improve business practices. Domestic corporations must establish a strategic logistics hub and related network while simultaneously pursuing value-added logistics businesses by increasing their manpower and building a logistics information system. This will strengthen their competitive edge and lead to system improvements. Conclusions - Domestic corporations must adopt a new paradigm and use more reasonable business laws, systems, and policies that are based on market-driven flexibility and transparency. Moreover, social norms and regulations should be established to help ensure political and social security. Korea must also develop a culture of tolerance for foreign companies. Finally, the paradigm defining the policy governing the development of the capital city and its satellite cities in this context must be changed.

The purpose of this study was to figure out related factors to the self-reported climacteric symptoms and the relationship among the health promoting behaviors, climacteric symptoms and degree of Sanhujori, the Korean traditional postpartal care. A cross-sectional survey design was employed in this study. The subjects were 108 middle-aged women who were non-hystrectomized and ranged in age from 40 to 60 years. They were selected in seoul and Kyoung-ki province, Korea, Data were collected from Oct.25 Nov. 10, 1997 by a structured questionnaire. The instruments used for this study were the revised health Promotion Lifestyle(HPLP) developed by Walker, Sechrist & Pender, and revised Climacteric Symptoms Scale developed by Chi, Sung Ai. the data were analyzed by the SPSS/$PC^+$ program using t-test, ANOVA and Scheffe test as a post hoc and Pearson Correlation Coefficient. The results of the study were as follows ; 1. The mean score of health promoting behaviors was low($2.42{\pm}0.35$). There were statistically significant differences in the score of health promoting behaviors according to the educational background, family income, marital satisfaction, whether or not taking a restorative food and degree of Sanhujori, especially the period (t=-2.07, F=2.60~7.57, p<0.05). 2. The mean score of score self-reported climacteric symptoms was 1.69%;99% of middle-aged women had symptoms. There were statically significant differences in the score of middle -aged women's self-reported climacteric symptoms according to the age, number of children, educational background, occupation, family income, marital satisfaction, whether or not receiving hormon replacement therapy (HRT) or consultation by a professional, perceived health status and self evaluation of Sanhujori(t=-2.04~3.69, F=2.87~11.63, p<0.05). 3. women's degree of Sanhujori was a positive correlation with health promoting behaviors(r=0.34, p=0.00) and negative correlation with the degree of self-reported climacteric symptoms(r=-0.19,p=0.03). 4. The influencing factors to the climacteric symptoms were self actualization, interpersonal support, and perceived health status among the health promoting behaviors with 57% of variance($R^2$=0.57). 5. The middle-aged women's type of coping pattern for the climacteric symptoms was classified as active behavioral coping, spiritual & psychological coping, and negative coping. In conclusion, to intervene the middle aged women's climacteric symptoms and develop nursing strategies for their health, health promoting behavior, especially ; self actualization, interpersonal support, and perceived health status should be considered. And, as the primary prevention strategy for women's health during the period of childbearing and also middle age, especially for the climacteric symptoms, Sanhujori should be reconsidered.
