After the construction (1398 year at first, secondarily reconstructed at 1448 year), the Soongryemoon (South Gate) had been preserved to late 19c without large damages. The present shape of the gate have been kept after the repairments of two times (1953, 1963). However, the rocks constituting the walls of the gate have been strongly weathered, exfoliated and cracked due to severe changes in the environment as traffic increase, air pollution and the subway which may seem also to cause the structural unstability. The rocks composed of the walls of the gate are almost of granites. On the rocks such deteriorations as onion structure, surface exfoliation, cracks, and edge breakout are developed. These deteriorations may be caused genetically by strong weathering, differential load due to possibly structural unstability, impact and unknown reasons. For the establishment of conservation plan, the factors of these deterioration phenomena and structural unstability must be quantitatively analyzed and diagnosed in detail.

Design is objective and universal human aesthetic activity. Design originally began with the purpose 'to make public's life abundant and increase their quality of living." However, design education has bee developed to foster human resource to maximize production of company in the name of 'important production method for company.' Therefore, common people has been had many opportunities to learn about design. General people could not be satisfied their demand to learn about design due to narrow opportunities. Public has had resistance feeling for design that it has been exclusively occupied by certain designers. Therefore, it is urgent to expand the object of design education and change the contents which have been focused on fostering design professionals. This research examined about the goal of public design education (self-expression, enjoying quality of life, culture, and wisdom of living) as a way to increase our life quality by recognizing the need of public design education based on various social phenomena which strongly shows people's desire to pursue aesthetic life.

최근 전 세계적으로 심각해지는 물 부족 현상과 수질오염으로 대량의 원수를 빠른 시간 내에 여과하기 위한 여과장치의 개발 및 효율성 향상을 위한 연구의 필요성이 증가되고 있다. 특히 여과필터의 내부구조에 의해 유동이 편중되는 현상이 발생하면 여과효율 및 여과필터 유지관리에 문제가 발생되기 때문에 최적의 여과필터를 설계하는 것이 중요하다. 이에 본 연구에서는 수리모형실험으로 검토하기에 어려움이 있는 여과기 내부구조에 대한 유동특성을 수치해석을 이용하여 검토하였다. 수치해석은 유한요소법 기반의 수치모형으로 여과기 내부를 상세하게 모의할 수 없기 때문에 유한체적법 기반인 ANSYS CFX 모형을 이용하였다. 여과기 내 여과필터는 두께 2.0 mm, 공극율 25%로 가정하고 다공성 기법(porous media)을 적용하였다. 검토를 위한 경계조건은 유입부에 목표 취수량, 유출부에 대기압 조건을 적용하였으며, 여과기에 비해 매우 작게 구성된 여과필터 내부의 유동특성을 검토하기 위해 여과기는 최소 3.0 mm, 여과필터는 1.0 mm의 격자를 적용하였다. 현재 실제 여과시설에 적용되고 있는 여과기 제품 형상을 기준으로 여과기 내부 흐름공간의 크기 및 각도 조정에 따른 유동특성을 검토하여 여과효율을 비교하였으며 통과유량, 유속, 유속벡터 등을 검토하여 균등한 유량과 유속이 발생되는 최적의 여과장치 구조를 도출하였다. 본 연구에서 여과기 내부 구조 변경에 따른 유동특성 검토를 통해 도출된 최적의 여과기 내부크기 및 각도에 대한 설계인자는 여과기 내 여과필터의 효율을 증가시킬 뿐만 아니라 내구성 증진에 도움이 될 것으로 예상된다.

하천에서 발생하는 유사량은 공급능력이 흐름의 이송능력보다 지배적인 경우 같은 유량이 발생하더라도 유사량이 다르게 관측될 수 있다. 특히 국내 하천과 같이 홍수기가 특정기간에 편중되어 연중 유량발생 편차가 매우 크게 나타나는 경우 이와 같은 현상이 더욱 두드러지게 발생한다. 즉, 대부분의 연중발생 유사량이 홍수시에 이동하고 홍수발생 초기와 후기의 유사 공급능력의 차이가 나타나는 국내하천의 경우 이를 기존의 유사이송공식으로 정량적인 유사량 값을 추정하는데는 한계가 있음을 의미한다. 따라서 본 연구에서는 국내 하천에서 실측한 유사량 자료를 종합하고 주요 지점별, 연도별, 계절별, 하천 유역별로 분류한 후 이를 분석하여 국내하천의 유사량 발생 특성을 규명하였다. 실측 유사량 데이터베이스는 국내 하천의 주요지점에서 2007년부터 2012년까지 측정한 자료로 구성되어 있으며 총 26개 지점 1,283개의 자료를 포함하고 있다. 4대강의 본류 대표지점으로 선정된 여주, 왜관, 공주, 나주지점을 대상으로 유량-총유사량 관계를 비교한 결과, 여주지점의 유량 증가에 따른 총유사량 증가 폭이 다른 대표지점들에 비해 가장 크게 나타나는 반면, 나주지점의 경우 제일 작은 값을 보인다. 또한 본류의 유량-유사량 관계식의 지수 값이 본류와 지류를 모두 포함한 관계식에 비해 더 크게 나타나는데 이는 지류에서는 본류보다 적은 유량이 발생하더라도 유사 이송량은 상대적으로 크게 발생한다는 것을 의미하며 그 이유는 본류와 지류에서 유사 이송이 지배적으로 발생하는 유량범위가 상이하기 때문에 나타나는 결과로 추정할 수 있다. 대표지점별 부유사 농도를 분석한 결과, 7월과 8월 부유사 농도에 비해 9월에 발생하는 부유사 농도가 현저히 낮은 값을 보이는데 이는 연중 홍수기 전반기에 유사 공급량이 상대적으로 많아 나타나는 현상으로 판단된다.

This study examined the case of women's conflict experience in small and medium size enterprises. Although the number of women working in business organizations is rapidly growing in Korea, discourse about them is still scarce. Some discourse about them focuses only on the productivity and inequality aspects within the organizations. Therefore, we need to examine their organizational lives through a more dynamic and performance based perspective. Especially, because conflicts experience by women within business organizations involve a variety of organizational interactions, they reveal the vivid reality with which working women face today. The existing conflict research studies focused on communication or interpersonal relationship are limited by the fact that they have primarily dealt with the variables such as conflict management styles. However, conflict research needs a more specific and wholistic interpretation because conflicts usually depend on their contexts and interaction dynamics. Therefore, the phenomenological methodology was employed as a more appropriate method for the current conflict study. Results shows that the two themes were identified regarding the conflict content. The first and second themes were the unfair situations and the hierarchical rank respectively. The three themes were identified regarding the attitudes about conflicts. They were the passive stance toward conflicts, the recognition of the gender difference, and the acknowledgement of the importance of the relational aspect respectively. Finally, three more themes were identified regarding the conflict management styles. The first, second and third themes were the passive responding, the aggressive responding and the positive conflict management respectively. In addition, the implications of the results and the suggestions for future studies were made.

As Digital technology developed, drawing animation, using traditional production method which expresses many feelings with drawn lines loses the youth group, the primary audience, to the realism of the digital cinema. Drawing animation, which drew attention of the youth by the spectacles in the film such as hectic pace, dynamics and punch, declined for a while. However, it has been developed a way to express pace and dynamics of its own by establishing an effective directing method, which combines digital technology as it is needed. This study has a purpose to investigate what causes the dynamics and feeling of fast movement of the character in Japanese limited animation. Though some action-animated films that heroes with supernatural powers take the leading role that feeling of velocity and dynamics are emphasized we compare the directing method before and after the introduction of the digital technology. This research reaches the conclusion by factoring each Bergson and McLuhan's discussion to the intervention of indexical signs and the audience's participation according to skipping technique. This study has a significance of researching the element of drawing animation that maximizes the expansion of the senses by defying the limitation of the law of physics through its unique way of directing together with growth of the hero films, which will continue.

The purpose of this study is to examine a direction for contents choice and transmission strategies of radio literature reading programs. For this, 129 picturebook contents used for EBS program of "children books for adults" in recent 6 months were collected and analyzed quantitatively and qualitatively based on Nicholajeva's societal and aesthetic approach. In terms of external literary elements, there were unequal distribution of published period, nation, company and genre. In terms of literary inner factors, they were excellently reflecting the stream and the tendency of modern children literature. Finally, in the process of turning visual texts into auditory texts, the program used diverse auditory transmission strategies. Based on these results, it is suggested that this program need to take into account reforming the contents selection practice to provide abundant literary experience for listeners and sophisticating the transmission effects adapted for a digital era.

The purpose of this study is to analyze mathematical tasks of Korea and the USA textbooks focused on conditions for parallelograms. In this study, structures of task, types of proof and reasoning, and levels of cognitive demand are investigated. The conclusion is as follows: First, with respect to structures of task, structures presented in the USA textbooks are more diverse. Second, with respect to types of proof and reasoning, Korea and the USA prefer IC task and DA task. And task types presented in the USA textbooks are more diverse. Third, with respect to levels of cognitive demand, in both Korea and the USA textbooks, PNC task and PWC task account most. And compared to the USA, Korea prefer algorithms. In addition, we find out implications for reconstruction of Korea textbook. It is as follows: First, with respect to structures of task and types of proof and reasoning, the diversity of composition needs to be raised. Second, with respect to levels of cognitive demand, the concentration in PNC task needs to be declined. And levels of cognitive demand on types of tasks need to be reconsidered. Third, with respect to tasks' topic and material, internal and external connectivities of mathematics need to be strengthened.
