The purpose of this study is to explore the life-political characteristics of elementary school students through practice cases of decision-making processes in schools. To this end, 29 sixth-grade students attending ○○ Elementary School in Paju, Gyeonggi-do, filled out pre-question and post-question papers. and, the researcher conducted an interview to understand the characteristics of elementary school students in the decision-making process. The researcher analyzed the data collected in the research process from a life-political perspective. The results are as follows. First, the position of elementary school students in the decision-making process expressed to solve problems that have occurred in school and the resulting practice patterns may appear differently. Second, students considered the elements of 'fairness' and 'fun by chance' important in the decision-making process to solve problems in elementary school. Third, it was found that students were influenced by the principles of 'sympathy', 'participation', and 'communication' in life-political in the decision-making process to solve problems that occurred in elementary school. Therefore, the elementary social studies curriculum needs to be applied by further expanding the problem situations that may occur in the life-world of elementary school students. The elementary social studies curriculum needs to organize the contents and methods of elementary political education centering on the life-world experience reflecting the life-political characteristics of elementary school students. 본 연구는 초등학생들의 학교 내 의사결정과정 사례를 통해 생활정치적 특성을 탐색하는 것이 목적이다. 이를 위해 경기도 파주시 ○○초등학교에 재학 중인 6학년 학생 29명을 대상으로 사전·사후 질문지를 작성하였고, 초등학생들의 의사결정과정에서 나타난 특성을 파악하기 위한 면담을 실행하였다. 그리고 연구 과정에서 수집한 자료는 생활정치적 관점으로 분석하였다. 그 결과는 다음과 같다. 첫째, 초등학생들이 의사결정과정에서 표현한 입장과 실천 양상은 학교 내에서 발생한 문제의 특성에 따라 불일치하게 나타날 수 있다. 둘째, 초등학생들은 학교 내 문제를 해결하기 위한 의사결정과정에서 ‘공평함’, ‘우연성에 의한 재미’의 요소를 중요하게 생각하였다. 셋째, 초등학생들은 학교 내에서 발생한 문제를 해결하기 위한 의사결정과정에서 생활정치의 공감·참여·소통 원리에 영향을 받는 것으로 나타났다. 이에 초등사회과교육과정은 초등학생들의 생활세계에서 발생할 수 있는 문제 상황들을 좀 더 확대하여 적용하고, 초등학생들의 생활정치적 특성이 반영된 생활세계 경험을 중심으로 초등정치교육 내용·방법을 구성할 필요가 있다.

The diffusional-thermal instability of diffusion flames in the premixed-flame regime is studied in a constant-density two-dimensional counterflow diffusion-flame configuration, to investigate the instability mechanism by which periodic wrinkling, travelling or pulsating of the reaction sheet can occur. Attention is focused on flames with small departures of the Lewis number from unity and with small values of the stoichiometric mixture fraction, so that the premixed-flame regime can be employed for activation-energy asymptotics. Cellular patterns will occur near quasisteady extinction when the Lewis number of the more completely consumed reactant is less than a critical value( ~ =0.7). Parametric studies for the instability onset conditions show that flames with smaller values of the Lewis number and stoichiometric mixture fraction and with larger values of the Zel'dovich number tend to be more unstable. For Lewis number greater than unity, near-extinction flame are found to exhibit either travelling instability or pulsating instability.

The center of resistance is a important determining factor of tooth movement pattern. Laser speckle interferometry, recently developed for noninvasive measurement of small displacements (microns), was used to detect the center of resistance of a maxillary canine which has normal tooth axis and distal curved root in dry human skull. Laser holographic interferometry was used to verify the results of laser speckle interferometry The following result were obtained; 1. In measurement of the degree of rotation, center of resistance was localized when the traction line passed 4.4/18.0 level from alveola crest to root apex. 2. In measurement of the degree of tipping, center of resistance was localized when the traction line passed 4.6/18.0 level from alveola crest to root apex. 3. In holographic determination, the center of resistance was observed when the traction line passed between 3mm to 6mm level from alveola crest to root apex, therefore the results using laser speckle interferometry was coincided with holographic results.

Nonlinear dynamics of striped diffusion flames, by the diffusional-thermal instability with Lewis numbers sufficiently less than unity, is numerically investigated by examining various two-dimensional flame-structure solutions. The Lewis numbers for fuel and oxidizer are assumed to be identical and an overall single-step Arrhenius-type chemical reaction rate is employed in the model. Particular attention is focused on identifying the flame-stripe solution branches corresponding to each distinct stripe pattern and hysteresis encountered during the transition. At a Damkohler number slightly greater than the extinction Damkohler number, eight-stripe solution first emerges from one dimensional solution. The eight-stripe solution survives Damkohler numbers much smaller than the extinction Damkohler number until the transition to four-stripe solution occurs at the first forward transition Damkohler number. At the second forward transition Damkohler number, somewhat smaller than the first transition Damkohler number, the transition to two-stripe solution occurs. However, anu further transition from two-stripe solution to one-stripe solution is not always possible even if one-stripe solution can be independently accessed for particular initial conditions. The Damkohler number ranges for two-stripe and one-stripe solutions are found to be virtually identical because each stripe is an independent structure if distance between stripes is sufficiently large. By increasing the Damkohler number, the backward transition can be observed. In comparison with the forward transition Damkohler numbers, the corresponding backward transition Damkohler numbers are always much greater, thereby indicating significant hysteresis between the stripe patterns of strained diffusion flames.

With its foreign trade rapidly expanding and with economic growth continuing at a substantial rate, China has become the largest container traffic generating country in the world. And with trend of container ships becoming larger and faster, the environment surrounding ports in North-East Asia are rapidly changing.The Yangsan, offshore port for Shanghai, being developed on the islands of Da Yangsan and Xiao Yangsan, some 30km offshore, and connected to the mainland by the six-lane highway Donghai bridge, opened phase one in late 2005 and phase two in 2006 respectively and will have 29 berths by 2012 and be able to handle 15 million TEU. The Port of Shanghai which passed Busan in terms of container volume further consolidated its position as the world's No. 3 port with an annual volume of 21.7 million TEU in 2006 and is likely to have emerged as the biggest container port in the world.The Port of Busan, the world's fifth largest container port, wants to survive as regional hub port. In this circumstance, the strategies of the Port of Busan should be established. 빠른 경제성장과 교역량의 증가에 힘입어 중국은 이제 세계에서 가장 많은 컨테이너 물동량을 처리한 국가가 되었다. 그리고 컨테이너선의 대형화와 신속화 추세에 발맞추어 동북아 주요항만이 직면하는 환경도 상당히 빠르게 변하고 있다. 상해항은 육지로부터 약 30km 떨어진 대양산과 소양산을 개발하여 2005년 말에 제1기 터미널을 그리고 2006년에 제2기 터미널을 개장하였다. 그리고 2012년까지 전체 29선석을 조성하여 1,500만 TEU를 처리할 예정으로 있다. 컨테이너 처리물량에서 부산항을 추월한 상해항은 2,006년도 연간 물동량을 약 2,170만 TEU를 처리하여 세계 제3위의 지위를 확고히 했으며, 향후 세계 제1위의 컨테이너 처리 항만으로 부상할 것으로 보인다. 세계 제5위의 컨테이너 처리항만이고, 동북아 중심항만이 되고자 하는 부산항에 양산항의 개장 및 향후 개발 계획에 따른 주변 상황에 능동적으로 대처하기 위한 다양한 대응전략을 제시해 본다.
