  • Background: Lung cancer has been the leading cause of cancer death in South Korea since 2000. This study examined the clinical characteristics of lung cancer patients diagnosed in a community hospital from the year 2000 to 2005, and compared these results with previously reported statistical data. Method: The lung cancer data in a form of an electronic medical record was downloaded from the hospital medical information system. The clinical characteristics of the 1,509 patients with lung cancer were analyzed retrospectively. Result: The mean age of the patients was 63.7 years. 82.5% and 74.5% of the patients were men and smokers, respectively. Squamous cell carcinoma (41.6%) was the most common pathology type followed by adenocarcinoma(32.3%) and small cell carcinoma(13.9%). When 604 patients who were diagnosed from 2000 to 2003 were compared with 905 patients diagnosed from 2004 to 2005, the age of patients increased significantly (61.5 years vs. 65.1 years; p<0.001) and the proportion of adenocarcinomas was significantly higher(29.3% vs. 34.4%; p=0.046). Conclusion: Among the major histology types of lung cancer, the incidence of adenocarcinoma has been increasing recently. The age of the lung cancer patients at diagnosis is getting older. This is despite the fact that the distributions of the initial anatomic stages have not changed significantly.

  • The purpose of this study is to provide necessary information to understand characteristics of vocational high school students and to enhance academic engagement through social support of teachers, leading to help research of teaching and learning strategy. A survey was conducted on 990 engineering major students attending 11 vocational high schools in Seoul metropolitan, Chungcheong, Jeolla, Kyeongsang and Kangwon regions. A questionnaire consists of measurement tools for the academic engagement (21 questions) and the social support of teachers (25 questions). The findings of this study are as follows: First, it is found that the level of students' academic engagement was high. But it appears that the students showed low engagement of emotion compared with that of behavior and cognition. There was no level difference according to gender, but there was a considerable difference according to a school year. The first year students' level of engagement was higher than the second and the third year students' in terms of cognition and emotion. Second, it shows that the level of the teachers' social support was normal, which was in the order of appraisal support, instrumental support, informational support, and emotional support. Especially, the level of appraisal support and instrumental support was most. Third, there were correlation and explanation between students' academic engagement and teachers' social support. Moreover, the result that teachers' emotional support has high correlation and explanation in qualitative terms of academic engagement support the importance. Therefore, it is concluded that the social support of teachers can make an positive influence on improving the academic engagement of students and provide students with adaptability and satisfaction with their school life, which may give students a positive effect in emotional development, self-formation, and complement.

  • Education about invention in elementary schools has thus far be conducted mostly through special activities and talented activities rather than through normal curricula. However, with the implementation of the 2007 amended curricula, invention education was reflected as a normal subject unit in the practical subject (technology and home economics) curricula, thereby laying groundwork for invention education being able to be provided through normal subject classes. Thus, at the time when invention education has been reflected as a normal subject unit, it is meaningful to research the effects of elementary school students' experience in invention education on their invention attitudes. This study sought to research the effects of elementary school students' experience or non-experience in invention education on their invention attitudes, targeting those in regional talent private schools who did not take invention talent classes, those who received invention education, and those who did not receive invention education at all. The conclusion of this study is outlined as follows. First, students' experience in invention education proved to be positive in boosting their invention attitude, and continued invention education experience like with students in regional talent invention schools significantly boosted their invention attitudes. Second, considering that students' actual experience in invention education had positive effects on their invention attitudes, the reflection of invention education in the amended curricula was found to be very desirable in improving elementary students' attitudes about invention. Third, according to gender, male students' invention attitude level was found to be higher than that of female students, suggesting that male students more worked on computers, electronic (smart) devices and machines in daily life, leading them to further develop invention attitudes.

  • Animation is an important tool to establish the identity of mutually related countries, as cultural contents with the economic value. That is, it is necessary that the Korean animation should extend the previous boundary of exchange, for the status of representative cultural industry in the 21st century global market. Especially, to overcome the regionally prejudiced and unbalanced cultural exchange, the possibility of extension with Czech animation, which has not had an active exchange with Korea, will be considered and the efficient method will be proposed. The Czech Republic is geopolitically located in the center of Europe and its infrastructure like industrial construction, investment environment, human resources is outstanding among Visegrad Group. The Czech Republic has a remarkable cultural border-crossing phenomenon, and as a complex country of cultural and religious characteristics of eastern and western European, it is a powerful nation leading Central Europe. Therefore, the animation exchange of Czech and Korea is valuable in culture and economy of both nations. Through such an animation exchange of both nations, not only Korean animation secures the diversity of exchange but also insignificant cultural exchange after formal establishment of diplomatic relations in 1990, will be revitalized and international firm relationship of both nations will be established. Therefore, as an activation plan or cultural exchange of Korea and the Czech Republic, concrete plan like Stop Motion Animation Workshop is proposed.

  • After TV Broadcasting service started, American Animation Industry changed dramatically. Through 1930th to 1940th, Major Animation Studios made every effort to adapt to new Animation production environment. Those efforts led rapid improvement of Animation again by succession of heritage in the golden age of American Animation. in spite of successful outcome, some critic like Bernard Oma blamed Animation on repeated chasing pattern, glamorized violence with exaggeration and humor caused by lack of idea. Nevertheless the decade passed by, achievement of the era still have influenced today. The animated films of the age have attractive power in comparison to today's works and Chuck Jones was a glamorous one of the age-leading masters. "Tom and Jerry" series, "Bugs Bunny", "Daffy Duck", and so on, he planned, designed characters and directed those masterpieces. In this study, episodes of "Tom and Jerry" that had been directed by Chuck Jones during 1963 and 1967 are analysed in the view point of direction style. In recently, Korean Animation Industry seems to be accumulated power for rising again by showing new animations that are adapted to new media. Thus, this study aims to give an idea for the new vision of Korean Animation through analysing Chuck Jones' Masterpieces.

  • Improving the design ability of idea developing and creative problem solving should be started from the primary school. Design education in the primary school should be not education for design but education by design. It helps students can naturally understand the basic concept of design and experience the process of activities. Therefore primary educational circle use the term of 'Design-related activities', or 'Design-Based Education'. It can be applied to variable themes of mathematics, science, music, society as well as Art. On the Basis of these literature review, the traditional design education as a part of the art education is analyzed in two aspects of its contents and behaviors. The contents in design education involve aesthetic·symbolic, useful·functional, and scientific·technological area. And, the basic design behaviors are classified with 'know', 'perceive', 'inquire', and so on. This concept becomes the analytic frame of the present condition of design education in Korean primary school. Through the analysis, it is found that the portion of scientific·technological area in contents and 'inquire' related behaviors are relatively very low. Also, the planning and teaching methods for leading children's opportunity of creative expression are found inadequate. This study proposes the potential capability and the integrative contents of design education in primary school.

  • Environment has formed characters of one society and the society has formed its characteristic cultural behaviors. Oppositely cultural behaviors make the characteristic products like environment and space products. It gives the idea that we can create cultural space by examining cultural characteristics. This research bases on the 5 cultural dimensions of Geert Hofstede to inspect cultural quality of Korea and the 10 cultural factors of Edward. T. Hall in order not to omit some part of cultural characters. From April 2004, KTX which is originated from TGV of France began toroll in Korea. It is interesting that the same interior of train is used by two different cultures. The method to find out the special quality of transportation culture of Korea passed 5 steps like following; 1) making a questionnaire to understand general concepts 2) observation to make dear what are the special behaviors in the interior of train 3) comparison valuation with marking sheet of the interiors of KTX and HSR in order to find out which space Korean people prefer 4) comparison of behaviors in the interior of KTX and TGV 5) Interviewing and surveying the opinions of passengers of KTX. With these methods it would be possible to seek out the characters, preferencesand needs for the interior space of train. There were remarkable things like following 1) importance of privacy from the other's eyes 2) seriousness of individual seat because of the short term transportation 3) necessity of continuous information because of 'Uncertainty Avoidance Culture' 4) absence of moving 5) requirement of bright and comfortable interior like one's inner room 6) preference to take a seat as a group with their friends or family due to 'Collective Culture' 7) self-defense and self-protection of one's baggage because of 'Uncertainty Avoidance Culture'. With these discoveries this research suggests guidelines to design interior of train of Korea.

  • During the last two decades, there has been an increasing interest in the impact of oral health on atherosclerosis and subsequent cardiovascular disease (CVD). To date, some periodontal pathogens including Porphyromonas gingivalis (P. gingivalis) have been reported to be relevant to CVD. Porphyromonas endodontalis (P. endodontalis), which shares approximately 87% sequence homology with P. gingivalis, is mostly found within infected root canals. However, recent studies reveal that this pathogen also resides in the dental plaque or periodontal pocket in patients with periodontitis. It has been shown that P. endodontalis invades human coronary artery endothelial cells (HCAEC) and coronary artery smooth muscle cells (CASMC). To evaluate whether P. endodontalis can participate in the progression of atherosclerosis and CVD, we examined the changes in transcriptional gene expression profiles of HCAEC responding to invaion by P. endodontalis in this study. The following results were obtained. 1. Porphyromonas endodontalis was invasive of HCAEC. 2. According to the microarray analysis, there were 625 genes upregulated more than two-folds, while there were 154 genes downregulated by half. 3. Upregulated genes were relevant to inflammatory cytokines, apoptosis, coagulation and immune response. Enhanced expression of MMP-1 was also noticeable. 4. The transcription profiles of the 10 selected genes examined by real-time PCR agreed well with those observed in the microarray analysis. Thus, these results show that P. endodontalis presents the potential to trigger and augment atherosclerosis leading to CVD.

  • The cultural cluster in Chuncheon was initiated in the late 1990s with the combination of diverse components, which were companies, a local government entity, educational institutions, and human resources. In order to hold ability of standing on its own way in a hard time when the local cultural industries could not had developed by themselves, it urgently required the encouragement policy in the name of industry development. GIMC (Gangwon Information & Multimedia Corporation) was established in this situation, and policy strategies for promoting the cultural cluster was decided on the basis of GIMC's strategies. This article analyzes the evolution process of the local cluster and suggests characteristics of its every stage--initiation, development, and decline--on the basis of cluster competition concept because of the problem to deal with the evolution process of cluster from the existing viewpoint. This article finds out that Chuncheon cluster embarked on cultural cluster strategies without concerning basic elements which had to be prepared from the initial stage. This problem worked as the serious obstacle hampering development of Chunchen cluster. This problem was the matter of policies in providing a direction of industry development as well as leading a local cultural cluster and led to a result of weakening the connection among cluster components. As a result, this article shows that the current status of Chuncheon cultural cluster is being entered the decline stage, and, therefore, suggests that the advanced policy to promote cluster for a next round is urgently needed. Stable closing the first round of cultural cluster policies and thorough preparation for the second round is the only practical solution to minimize side effects of cluster decline. It is the prerequisite to restore trust and, at the same time, reinforce relationship between members who consist of Chuncheon cultural cluster.

  • This study is an attempt to look into the future role of the ROKN and to provide a strategic way forward with a special focus on naval strategic concept and force planning. To accomplish this goal, this research takes four sequential steps for analysis: 1) assessing the role and utility of naval power of ROKN since its foundation back in 1945; 2) forecasting features of various maritime threats to influence the security of Korea in the future directly or indirectly; 3) identifying the roles to be undertaken by future ROKN; and 4) recommending Korean way of naval force planning and the operational concept of naval power. This study seeks to show that ROKN needs comprehensive role to better serve the nation with respect to national security, national prosperity and development, and future battle-space management. To safeguard the national security of Korea, it suggests three roles: 1) national guard for the peaceful unification; 2) protector of the maritime sovereignty; and 3) suppressor to maritime threats. Three more roles are highlighted for national prosperity: 1) escort of the national economy; 2) guardian for national maritime activities; and 3) contributor to the world peace. These roles need to be closely connected with the role for the battle-space management. This paper addresses the need for a dramatic shift of the central operational domain from land to maritime in the future. This will eventually offer future ROKN a leading role for developing strategic concept and force planning rather than merely a supporting one. This study finally suggests 'balanced' strategy both in concept development and force planning. A balanced force planning is a 'must' rather than an 'option' when considering a division of function between Task Fleets and Area Fleets, constructing cutting-edge conventional forces such as Aegis destroyer, CVs, or submarines, and the mix of high-profile platform and low-profile when composing future fleets. A 'balance' is also needed in operational concept. The fleet should be prepared to fulfill its missions based on two different types of force operation i.e., coercive or cooperative application of the utility of naval force. The findings and recommendations of the study are relevant today, and will be increasingly important in the future to achieve various political goals required by enhancing the utility of naval power.
