  • The purpose of this study was to analyze the school location and site planning direction for land use planning of public land development. And this research proposed the direction of small park in school. So this research present the implication on urban planning and design for architecture, park-school complex. This study perform the relationship analysis on location of school and park. The result follows as this : 1) land use planning : Location and space of park-school must be checked in advance. Schools and parks are placed together. The park is located south of the school. 2) school site planning : Small field for dynamic activity is needed in school. The character of small park in school is relationship of educational programs. 3) management : CCTV is installed at school. Bright lights are placed in school. This result will be used in decision-making-process of land use planning, public land development construction, urban design and city policy.

  • Thanks to the characteristic of high-rise buildings, the increase of wind speed according to the height of a building makes it possible to use high wind power resources, many countries led by some advanced nations are recently making steady and persistent effort in introducing small wind turbine systems as a step to lower electric power load in high-rise buildings. The aim of this research is to propose an optimum application process of a small wind turbine system in high-rise buildings. To achieve this goal, the case studies on the applications of high-rise and tall buildings were conducted and the best application among them was selected. On the basis of the case studies, an application process was proposed.

  • In order to design an effective foot surface which can provide adequate friction for a self-propelled medical microrobot moving inside the small intestine, frictional mechanisms between the small intestine inner wall and the foot surface of the robot must be understood. In this paper, mechanical interlocking effect was considered to design the surface of the foot that can generate the desired frictional force. The concept of the design was derived from the hookworm that lives inside the small intestine. Hookwarms are known to adhere to the small intestine wall by interlocking with villi on the surface of the small intestine. The interlocking mechanism was considered as the main frictional mechanism for the design of the microrobot foot surface in this work. 2 mm and 6 mm diameter solid and hollow cylindrical shaped foot specimens were designed and tested to assess the frictional force between the specimens and the porcine small intestine specimen.

  • Recently, capsule endoscope was developed to observe small intestine in human body. However, the capsule does not have any locomotive ability, which reduces the benefit of the capsule endoscope. Many researches have done to give locomotion to the capsule, still it consumes too much power to generate the motion by small battery. One of the moving method is electrical stimulus that consumes less power than many methods. The electrical stimulus method causes contraction in the small intestine, and it moves the capsule. Some of papers showed it is possible to guide the capsule by electrical stimulus, however the relationship between electrical stimulus at the mucous and contraction force in the small intestine is not reported, yet. In this paper, the mucous in the small intestine was stimulated, and measured the contraction force in the small intestine is shown. The result shows, the relationship between electrical stimulus parameters (voltage, duration) and contraction force. Also, equation between electrical stimulus parameters and contraction force is roughly induced.

  • 이 연구의 목적은 고등학교 화학 I 교과에서 small-scale chemistry (SSC)를 활용한 실험수업이 고등학생들의 학업성취도와 과학적 태도 및 과학에 관련된 태도에 미치는 영향을 알아보는 것이다. 연구를 위하여 고등학교 2학년 2개 학급을 실험집단과 통제집단으로 나누어 실험집단에는 SSC를 활용한 실험수업을, 통제집단에는 교과서에 제시된 전통적인 실험수업을 실시하였다. 연구 결과, SSC를 활용한 실험수업은 전통적인 실험수업에 비해 학업성취도를 향상시키는 효과가 있었으며, 과학적 태도에서는 자진성과 끈기성 및 협동성을, 과학에 관련된 태도에서는 과학의 사회적 의미와 과학교과에 대한 태도 및 과학에 대한 태도를 향상시키는 효과가 있었다. 그러므로 교육 현장에서는 SSC를 활용한 실험수업을 고등학교 화학교과에 적극적으로 활용할 필요가 있다.

  • Small cell carcinoma is mainly found in the lungs and extrapulmonary origins of small cell carcinoma in GI tract, head and neck, genitourinary system consists only 4% of the tumor. Thus, small cell carcinoma of the parotid gland is an extremely rare disease. Extrapulmonary small cell carcinoma is characterized by an aggressive clinical course with early metastasis. We report a case of small cell carcinoma of parotid gland in a 82-year-old woman with painless neck mass, who was managed with radiation therapy after surgery and review of relevant literatures.

  • The small craft including jet-board for leisure are commonly smaller than the general commercial vessels. For the floating vessel, the motion analysis is significantly important component to design the shape. It is, however, hardly predicting its behavior by using conventional boundary element method due to violating small amplitude assumption for potential theory. The computational fluid dynamics method can afford to simulate such small craft, but its grid system was not able to calculate motion, because movable body disturbs the grid system by confliction. The dynamics fluid body interaction model with over-set mesh system can be dealt with movable floating body under irregular ocean wave. In this study, several cases were considered to reveal that DFBI is essential method to predict floating body motion. The single phase simulate was conducted to establish the shape perfection, and then the validated vessel was simulated with ocean waves weather DFBI option on or off. Through the comparison, the results between the cases of DFBI on and off shows significantly difference. It was claimed that the DFBI was necessary not only to calculation body motion, but also to predict accurate drag and lift force on the floating body for small size craft.

  • The purpose of this project is to create small parks in elementary schools in order to improve the educational environment and also to increase the amount of greenspace in the city. Above all, the main goal is to create space for local residents in which they can enjoy their leisure time. During a basic investigation and document investigation of elementary schools in Daegu, I placed the priority on choosing the schools that showed the most promise. Also, by doing a survey about the present conditions at schools, I verified, compared, and analyzed the validity of creating small parks in elementary schools. The summary of the results are as follows. The average area available for building small parte in Daegu elementary schools is $7,447m^2$. Even though this area is not as large as a neighborhood parti the difference is not that great. Therefore, I assumed that building small parks in schools would be as effective as building neighborhood parks. The standard size for a children's parks is $1,500m^2$, and if small parks were to be constructed in all school areas with available space larger than a children's park (i.e., larger than $1,500m^2$), the amount of added park greenspace would equal $1,217,953m^2$. The number of schools with areas under $1,500m^2$ is only 3% of all schools in which small parte can be created(5 schools). Schools that have between $1,500m^2$ and $8,000m^2$of greenspace make up 59.7% of all schools in which small parte can be created (98 schools). Schools that have greenspace of more than $8,000m^2$ make up 37% of all school in which small parks can be created (61 schools). The standard area for neighborhood parte is $10,000m^2$ (building-to-land ratio 20%). Schools that have areas that are larger than the standard area for neighborhood parte make up 31% of all elementary schools in Daegu (61 schools). Therefore city greenspace would increase to a total of $694,805m^2$ by making use of these schools, which would represent 7% of the park greenspace in Daegu.
