  • Human mind consists of what he or she knows, namely 'a portion of awareness', as well as of what he or she does not know, namely 'a portion of unawareness'.1) Self refers to both consciousness and unconsciousness, whereas self-growth seems to be an ability with which a human being appropriately faces with the hidden desire and resistance of unconsciousness for himself and maintains its balance and unification with consciousness harmoniously. On this account, examination on character's unconsciousness seems to be an important methodological means to prospect for the original looks of self, based on character's internal psychology, and to grasp the change and growth throughout the course. Study subjects, namely and , are quite similar in internal/external factors around the leading character. Two girl leading characters, who have nested in parental influences and boundaries, confront with unfamiliar circumstances under the abrupt absence of parents. In order to resist contradictory and irrational situations there and to restore all the things to its original places, both carry out a hard adventure. Interestingly, both characters are similar in their unconscious characteristics, but they take different channels for their journey, confronting attitudes and changes of internal self. The purpose of this study was to examine the concrete origin of two characters' unconsciousness and then comparatively analyze the role of leading character's unconsciousness in the drama and its effects on the whole work. Therefore, the author tried to prove such a hypothesis as the probability and persuasiveness of story could be found out through establishing a character of higher completion degree and connecting between situations and events that are most appropriate for character's internal unconscious psychology.

  • In this study, performance (particle removal efficiency and breathing resistance) of several commercially available face masks (electrostatic filter masks (KF80 certified), a nanofiber filter mask (KF80 certified), and an uncertified mask) with their filter structure and composition were evaluated. Also, effects of relative humidity (RH) of incoming air, water and alcohol exposure, and reusability on performance of face masks were examined. Monodisperse and polydisperse sodium chloride particles were used as test aerosols. Except the uncertified mask filter, PM2.5 removal efficiency was found to be higher than 90%, and the nanofiber filter mask had the highest quality factor due to the low pressure drop and high removal efficiency (nanofibers were arranged in a densely packed pore structure and contained a significant amount of fluorine in addition to carbon and oxygen). In the case of the KF80 certified mask, the removal efficiency was little affected when the RH of incoming air increased. When the mask filters were soaked in water, the removal efficiency of mask filters was degraded. In particular, the uncertified mask filter showed the highest removal efficiency degradation (26%). When the mask was soaked in alcohol, the removal efficiency also decreased with the greater degree than the water soaking case. The nanofiber mask filter showed the strongest resistance to alcohol exposure among tested mask filters. During evaluation of reusability of masks in real life, the removal efficiency of certified mask filter was less than 4% for 5 consecutive days (2 hours per day), while the removal efficiency of uncertified mask filter significantly decreased by 30% after 5 days.

  • Unreduced small bowel intussusception requires operative treatment although the rate of spontaneous reduction is 60 to 70 %. The aim of this study is to compare clinical characteristics and outcome between spontaneous reduction and operation group and to analyze factors related to decisions to treat small bowel intussusceptions. The records of 25 patients with small bowel intussusceptions treated in Seoul National University Children's Hospital from January 1999 to August 2009 were reviewed respectively. Spontaneous reduction group (n=12, 48 %) had signs and symptoms of vomiting, abdominal pain, currant jelly stool, abdominal distension, fever, increased CRP but no rebound tenderness. One of them had been diagnosed with Henoch-Schonlein purpura and no one displayed pathologic leading point by image study. Operation group (n=13, 52 %) consisted of patients who had primary surgery. Their signs and symptoms were similar to spontaneous reduction group. Seven of them had underlying diseases such as Crohn' disease, ALL, Lymphoma, Peutz-Jeghers syndrome (n=3), post-transplanted state of liver and 2 of them displayed Peutz-Jeghers polyp and Meckel's diverticulum as pathologic leading point by preoperative ultrasonography. Mean relieve interval (interval between onset of symptoms and reduction/operation) was 1.78 days in spontaneous reduction group and 2.25 days in operation group (p=0.341). Seven of operation group had manual reduction and 6 out of 7 received segmental resection of the small bowel. No one of them underwent manual reduction and all of them underwent segmental resection were found to have pathologic leading points [Peutz-Jeghers polyp (n=3), Meckel's diverticulum (n=2), lymphoma (n=1)] during operation. In conclusion, 48% of small bowel intussusceptions resolved spontaneously. Patients' symptoms and relieve intervals were not related to the operative decisions. We therefore recommend significant factors for determining treatment plan such as change of clinical symptoms, underlying disease or pathologic leading point by imaging.

  • The purpose of this study was to show how to organize small groups on the project method class in technical high school. The subjects of this study were two classes including 40 second-year students (20 students in each class) of architecture design course in D technical high school located in Taejeon metropolitan city. The method of this study was to investigate the ego-state by the ego-gram practicing Transactional Analysis. Total 10 small groups were organized. Each group had 4 members. And the same quality of egostate small group was organized by the 4 students who have high score on NP and AC. The different in kind small group was organized by the 4 students, each of whom has NP leading, A leading, FC leading and AC leading score. After the target small group was video- taped, students' verbal interaction was written into transcripts. Their individual states were analysed by the frame of verbal interaction. The result of this study was that the same quality of TAOK small group had more active interaction(110 times) than different in kind small group(87 times). The frequency of complementary transaction was also higher plenty in the same quality of TAOK small group.

  • The purpose of this study is to analyze leading teachers' opinions on key competencies and subject competencies presented in the 2015 revised national curriculum and to draw implications for competency-based curriculum development and implementation. The research findings show that leading teachers are generally positive about the introduction of key competencies, subject competencies setting and its feasibility and recognize that the key competencies are highly related to the subject competencies of each subject. However, it is judged that the key competencies and subject competencies are not embodied well in every aspect of the curriculum documents. They also recognize that in the practice of competency education, supporting the development of teachers' ability to conduct student-centered classes in a culture that enables voluntary research efforts of the teacher community can be the biggest issue rather than external support such as development of competency-centered textbooks or consulting and supervision. Finally, we propose the need for support and policy that enable voluntary efforts for interdisciplinary cooperation and strengthening teacher capacity rather than developing competency-centered textbooks; specification of competency education in educational content, pedagogical methods and assessment; reconsideration of subject competencies setting; maintaining the relationship between key competency and items that guide educational goals.

  • The purpose of this study is to analyze the economic efficiency of the policy implemented by Ministry of Culture, Sports and Tourism on leading company in sport industry. The leading companies in sport industry are those who have a certain amount of sales in sport industry and the ones with potential to become global companies. Supporting areas include business advancement, overseas market development, and overseas PR marketing integration support. The research is performed by developing the equilibrium model composed of supply as well as demand and applying input-output analysis. The economic efficiency is estimated to in the form of changes in the sales of corporations and the ripple effect of the national economy. The results of the study are as follows. First, it is estimated that the sales growth rate of the company due to the implementation of the policy is from 3.74% to 5.19%. Second, the increase in sales reaches to a maximum of KRW 4,081 billion with a minimum of KRW 1,573 million, depending on the size of the company. Third, it is estimated that the production inducement effect for the national economy is from KRW 36 billion to KRW 93.4 billion. Fourth, the induced value added for the national economy is estimated to be at least KRW 11.3 billion, up to KRW 29.2 billion.

  • In this paper, the fluid dynamic forces and performances of a moving airfoil in the low Reynolds number flow is addressed. In order to simulate the necessary propulsive force for the moving airfoil in a low Reynolds number flow, a lattice-Boltzmann method is used. The critical Reynolds and Strouhal numbers for the thrust generation are investigated for the four propulsion types. It was found that the Normal P&D type produces the largest thrust with the highest efficiency among the investigated types. The leading edge of the airfoil has an effect of deciding the force production types, whereas the trailing edge of the airfoil plays an important role in augmenting or reducing the instability produced by the leading edge oscillation. It is believed that present results can be used to decide the optimal propulsion types for the given Reynolds number flow.

  • The purpose of this study is to examine the political and social statements through fashion design, by comparing with more activated statements in the general design area. To achieve this, the documentary study and practical case study have been executed. First of all, the meaning of design politics was defined and the cases of design practice of political and social statements were reviewed and classified historically. Traditionally, designs have been inextricably linked with political authorities and ideologies. As propaganda, it has been used for power authority to seize power and maintain dominance. On the contrary, they could be an instrument to resist and criticize against contemporary power authority and dominant. Next, the political and social statements were traced historically through fashion design on the basis of the two previously reviewed categories. And then, comparing political and social statements between design and fashion design, the contents and ways of their expressions were similar. In design, there were more various ways when the designers were leading collective behavior, but in fashion design, there were more leading voices of socio-political organizations and resistant counter culture groups. Now, new trends are rising constantly where individual designers' creations express many different socio-political beliefs. This study which inquires designers' political and social involvement will be helpful in making people rethink the social role of fashion design and encouraging conscious fashion design activism.

  • The fast and competitive urbanization has accelerated unbalanced land utilization and housing, thereby producing large number of decaying areas and socially disadvantaged population, while generally promoted citizen's quality of life. Since rental housing policy, therefore, has emerged as a major important issue to solve these ever increasing problems, new concepts in leading examples need to be explored to stimulate creative ideas for future housing improvement. The purpose of this research is to extract successful factors of a leading rental housing 'Manhattan Plaza' in New York city, expecting useful implications for housing improvement in Korea. Field visit and in-depth interview for data collection and qualitative approach for analysis were carried out. As results, its successful sustainability and fame were found to be attributable to following concepts, such as, socially integrative mix of diverse residents, residents' participation in management, privacy respect administration, considerate planning and design features of physical environment. The latter, especially, were prominent in peripheral spaces, indoor and outdoor community spaces, and private spaces. Based on the results, suggestions were made for future Korean rental housing development.
