Ten years have passed since the Demolishing Walls Campaign has started in Daegu. Recently, the campaign influenced to the other cities in Korea, such as Seoul, Incheon and Busan with various names regarding cities' circumstances. In these context, the study aims to highlight the identity of the Demolishing Walls Campaign compare Daegu with other cities where similar movement has started. In addition, the study evaluates the campaign in terms of physical, psychological and economical aspects to suggest some practical suggestion for the development of the campaign based on questionnaire survey. The research findings are as follows. The research shows that the identity of the Daegu Campaign is started by bottom-up approach based on citizens' participation compare with others cities' campaigns which are mainly started by the local government so called top-down method. The Daegu campaign influences the local people aware of their potential abilities in positively improving urban environment. The results of survey also highlights the advantages of green spaces which by the campaign in terms of environmental and economical aspects. Newly generating urban greens accept and store heat which Influences urban microclimate conditions and it possibly affects energy savings of the city. Most of survey participants eager to continue this campaign which shows positive results in various aspects by the local people. Therefore, the city government building a coalition of local people, NGOs, and interest group to keep the identity of the campaign in Daegu.

Objectives: This article reviewed researches on intersectoral partnership of school health programs to suggest importance, current status and development plan of those. Methods: Domestic research papers were screened though Research Information Sharing Service (RISS), Koreanstudies Information Service System (KISS), Medical Library Information System (MEDLIS), Korean Medical Database (KMbase), and digital national assembly library. International papers were searched mainly via Pubmed. Results: Since intersectoral partnership is effective, comprehensive and universal approach for school health programs, many collaborative programs are universally progressing in various domain including smoking, alcohol, mental health and sexual behavior. On the other hand, intersectoral partnership of school health programs in Korea is still in the beginning stage, and there are few intersectoral partnerships. Moreover, there are several limitations including top-down approach, passive participation and lack of studies on the effect of intersectoral partnership. However, intersectoral partnerships in school health program including tuberculosis control system in school or WEE project are in progress, so it is worth looking forward in the future. Conclusions: To achieve successful intersectoral partnership in school health programs, appropriate partnership guideline for Korean society, policy support, active participation and improvement of consciousness in community stakeholders are needed.

Design of settlement space is a complicated process while reasonable spatial layout bears great significance on the development and resource allocation of a settlement. The study proposes a weighted L-system generation algorithm based on CA (Cellular Automation) model which tags the spatial attributes of cells through changes in their state during the evolution of CA and thus identifies the spatial growth mode of a settlement. The entrance area of the Caidian Botanical and Animal Garden is used a case study for the model. A design method is proposed which starts from the internal logics of spatial generation, explores possibility of spatial rules and realizes the quantitative analysis and dynamic control of the design process. Taking a top-down approach, the design method takes into account the site information, studies the spatial generation mechanism of settlements and further presents a engine for the generation of multiple layout proposals based on different rules. A optimal solution is acquired using GA (Genetic Algorithm) which generates a settlement spatial layout carrying site information and dynamically linked to the surround environment. The study aims to propose a design method to optimize the spatial layout of the complex settlement system based on parametric generation.

Combustion phenomena in a sub-millimeter scale combustor have been investigated. To evaluate scale effect on flame propagation characteristics, a cylindrical combustion chamber with variable depth was built in-house. The combustor was charged with premixed gas of hydrogen and air and ignited electronically. A piezo electric pressure transducer recorded transient pressure after the ignition. Measurements were made at different test conditions specified with chamber depth and initial pressure as parameters. Visual observation was made through a quartz glass window on top side of the combustion chamber using high speed digital video camera. From the pressure data, available work was estimated and compared with energy input required for stable ignition. The preliminary results suggested that the net thermal energy release is sufficient to generate power and enables a combustor of the size in the present study to be used as the energy source of a micro power devices .

본 연구의 목적은 비디오/오디오 프로토콜 분석 방식을 이용해서 텍스타일 디자인 프로세스 중 모티브 개발 단계에서 디지털 나염(DTP : Digital Textile Printing) 전용 캐드(CAD)와 같은 디자인 저작도구를 설계할 때 어떤 요소에 중점을 두고 개발 할 것인지에 대한 향상된 지침을 마련하는데 있다. 텍스타일 디자인 프로세스에 대한 프로토콜 분석을 위해 선행 연구를 고찰하여 디자인 행동 범주의 틀을 하향식(top-down)방식으로 설정하고 실제 행동 프로토콜 (action protocol) 분석을 통해 상향식(bottom-up)방식으로 세부 디자인 행동을 도출하였다. 텍스타일 디자인은 선행연구의 건축디자인과는 다른 특징을 지니기 때문에 프로토콜 분석에서도 새로운 디자인 행동 범주(action category)가 필요하게 되었다. 이를 위하여 모델 휴먼 프로세서(Model Human Processor)이론을 근거로 디자인 행동을 모터 행동(motor action), 지각 행동(perceptual action), 인지 행동(cognitive action)의 세 가지 범주[4]로 나누었으며 텍스타일 디자인 프로세스에 적합한 코딩 스킴(coding scheme)을 개발하였다. 본 연구에서는 이 새로운 코딩 스킴을 토대로 디자인 저작도구에 대한 디자이너의 인지적 모형(Cognitive Model)을 개발하였다. 이렇게 개발된 디자이너의 인지적 모형은 디지털 나염을 기반으로 하는 모티브 개발 단계에서 스케치와 렌더링에 대한 디자인 저작 도구의 향상된 설계지침 뿐만 아니라 방향도 시사하였다.

To increase fishery resources in coastal waters, juvenile fish and bivalves are artificially released every year in Korea. This study provides a methodology to estimate an optimal release quantity based on the carrying capacity of the receiving basins. Carrying capacity was defined by E.p. Odum's theory of ecosystem development as the upper limit of biomass, where total system respiration equals total primary production. The Ecopath trophic ecological model was used to determine carrying capacity in the surfzone ecosystem of Bangjukpo on the southern coast of Korea. Using a top-down control method, various biomasses of fish groups were given to the simulation, with primary production constant and no catch. The results showed that biomass of selected fish groups increased by two orders of magnitude, yielding a five-fold increase in overall consumer biomass. The resultant values are 10 times higher than those estimated in open seas. This can be explained by higher primary production in the Bangjukpo surfzone ecosystem. This method can be used for strategic releases and ecosystem management, particularly when based on an ecological background.

In medicine, rapid changes in information, technology, socio-economic interests, and globalization affect the medical education focused on the competencies of doctors, and the number of medical schools that are adopting an outcome-based curriculum (OBC) is increasing worldwide. This paper introduces the OBC model of 5 trailblazing medical schools from the UK, US, and Australia, comparing their unique features, followed by brief comment about Canada and the EU as well. On developing an OBC, the process of establishing the top outcomes for graduates is similar and the outcomes comprise knowledge, skills, and attitudes about science, patients, colleagues, society, and themselves. Implementing the outcomes down into the sub-levels of the curriculum is much more complicated and time-consuming. Assessing the achievement of every outcome is essential and requires the use of many tools in addition to the traditional written examination. From the perspective of adult learning theory, self-directed learning, team-learning, and individual and flexible achievement are tested and executed in an OBC. The gradual expansion and further innovation of an OBC is expected so that tomorrow's doctors will be able to meet the challenges of the future.

This study investigates issues in relation to text segmenting, in particular, line breaks in Korean language textbooks. Research on L1 and L2 reading has shown that readers process texts by chunking (grouping words into phrases or meaningful syntactic units) and, therefore, phrase-cued texts are helpful for readers whose syntactic knowledge has not yet been fully developed. In other words, it would be important for language textbooks to avoid awkward syntactic divisions at the end of a line, in particular, those textbooks for beginners and intermediate level learners. According to our analysis of a number of major Korean language textbooks for beginner-level learners, however, many textbooks were found to display line-breaks of awkward syntactic division. Moreover, some textbooks displayed frequent instances where a single word (or eojeol in the case of Korean) is split between different lines. This can hamper not only learners' learning of the rules of spaces between eojeols in Korean, but also learners' development in automatic word recognition, which is an essential part of reading processes. Based on the findings of our textbook analysis and of existing research on reading, this study suggests ways to overcome awkward line-breaks in Korean language textbooks.

This paper presents a laboratory experiment on data acquisition technique that applied to the gamma radiation scanning coupled with computed tomography (CT) technique for inspection of broken nozzle inside the vertical vessel. The acquisition technique was developed to inspect a large diameter vessel when suspicious problem location is not easily accessed. This technique allows the installation of gamma radiation source (Cesium 137, Cs-137), and detectors (Sodium Iodine. NaI(Tl)) from the accessible location to the required location and performs the scanning by designed pattern. To demonstrate the designed technique, top opened tank which installed with six cut steel pipes diameter of 76.2 mm (3") at a certain position was selected. They were assumed to be a gas riser pipes inside the vessel. Three studied cases were performed, (a) projection of well installed six pipes, (b) projection of one out of six broken pipe and (c) one of nozzle was assumed to be failure and fell down until one out of six pipes was broken and obstructed by nozzle. Results clearly indicated the capability of developed technique to distinguish between normal situation case and abnormal situation cases.
