본 연구는 다래 및 교잡종 다래의 수관층위에 따른 광환경 차이에 따른 광합성능력, 엽 그리고 과실의 특성 변화를 구명하고자 실시하였다. 수관층위별에 따른 광합성속도를 측정한 결과, 수관층위가 높아질수록 광합성 속도가 증가하여 광도 $1,000{\mu}mol{\cdot}m^{-2}s^{-1}$에서 하층($5.82{\mu}mol\;CO_2\;m^{-2}s^{-1}$), 중층($7.11{\mu}mol\;CO_2\;m^{-2}s^{-1}$), 상층($9.54{\mu}mol\;CO_2\;m^{-2}s^{-1}$)의 순으로 높은 광합성속도를 나타냈다. 엽의 경우, 수관층위가 높아질수록 엽폭과 엽장 그리고 엽면적이 감소하였다. 즉, 하층, 중층, 상층 수관층위가 증가할수록 엽면적은 162.8, 90.9, $68.3cm^2$ 로 각각 감소하였다. 과실의 경우에는 수관층위가 높아질수록 과실 중량 및 과실 폭과 과실 길이가 증가하는 경향을 나타냈다. 이러한 결과는 상층의 높은 광합성능력이 과실의 생육에 영향을 미친 것으로 수관상층부로의 결과지 유도를 통해 대립성 다래 과실생산이 가능할 것으로 여겨진다.

A change of Finsler metric L(x,y)longrightarrowL(x,y) is called a Randers change of L, if L(x,y) = L(x,y) +$\rho$(x,y), where $\rho$(x,y) = $\rho$(sub)i(x)y(sup)i is a 1-form on a smooth manifold M(sup)n. Let us consider the special Randers change of Finsler metric LlongrightarrowL = L + $\beta$ by $\beta$. On the basis of this special Randers change, the purpose of the present paper is devoted to studying the conditions for Finsler space F(sup)n which are transformed by a special Randers change of Finsler spaces F(sup)n with ($\alpha$,$\beta$)-metrics of Douglas type to be also of Douglas type, and vice versa.

This study was conducted in an inclusion class in M Inclusion Day Care Center in Busan. Thirteen sessions of cooperation teaching were applied in the inclusion class. In this sense, the purpose of this study was to identify what kinds of change occurred in the perspectives of teachers' role on both the general education teacher and the special education teacher during cooperation teaching. The data were collected through participation observations, teachers' reflective journals, and interviews. From the results of the study, it could be suggested that various types of teaching strategies need to be introduced to both teachers from the beginning of inclusion so that the general teacher and the special education teacher could understand each others roles and tasks, share opinions and ideas about daily activities, and experience the roles of the other teacher.

This study deals with the design of snow plow for the special equipment vehicle. The purpose of the study is to develop the snow plow that can install in the special equipment vehicle such as clean up vehicle or dump truck in winter season. To do so, it is designed by 3 sub-assembly - snow shovel, main frame, and hydraulic cylinder and its support. The snow shovel consists of 3 pieces to meet the road profile and to exchange easily the damaged parts. Main frame connects the snow shovel with the hydraulic cylinder and its support and supports the weight of snow. Finally, the hydraulic cylinder and its support move the snow shovel up and down and tilt it. We designed it using 3D commercial CAD software for concurrent engineering design.

As global climate change leaded to extensive natural disaster and radical deterioration of infrastructures, there was increased attentions for the evaluation of infrastructures. After the collapse of Seongsu Bridge in 1994, Korea has enacted the "Special act on safety and maintenance of facilities" and secured the safety of facilities using systematic and periodic safety inspections. However, current facility inspections are mainly performed by the physical defect and structural analysis, and do not properly consider the serviceability of infrastructure such as capacity of facility and user's satisfaction. Thus, the purpose of the study is to develop an evaluation criteria for serviceability of infrastructures and finally leading to the revision of "Special Act on safety and maintenance of facilities in rational manner.

Recently, a wide variety of studies on future learning have appeared owing to rapid advances in information and communication technology (ICT) and increased discussion about core competencies in twenty-first-century learning. These studies, though insufficient in number, cover various fields such as architecture (design of the learning space), education (learning model), and technology (adaptation of mobile devices). However, these studies focus on mainstream students and do not discuss the future situation of inclusive education with regard to both mainstream and students with physical disabilities. Hence, in order to fill this gap, the present study explores the perceptions and ideas held by special education preservice teachers on the future learning space with regard to school design and peer-to-peer feedback. For this purpose, these preservice teachers' design proposals about future school were collected and analyzed. In conclusion, special education preservice teachers perceive the future learning space as an inclusive environment in which smart technology is incorporated. Future learning environment were categorized in terms of flexible, ubiquitous technology, physical and mental health, safety, and spaces with facilities for students with physical disabilities.

The purpose of this study is to investigate university students' eating habits during special occasions and the willingness to pass on traditions of cooking certain dishes on special occasions to the next generation. The procedure of this study included a questionnaire to collect data for this study. The results are summarized as fellows: there were 689 participants. 314 male and 375 female. Most participants were nuclear families(84.5%), Practicing cooking traditions during the special occasions at home on New year's day. Chusuk, Ceremony of a forefather's death, the 15th of the first month. and Winter solstice exceeded 70% of households. In every event, most persons who make the food during the special events at home are mothers. Furthermore, most persons who teach the cooking method are mothers. too. Most foods which were taken In the annual events generally were as fellows : rice cake soup on New Year's Day. boiled rice admixed with four other staple cereals on the 15th of the first month, half-moon-shaped rice cake on Chusuk. a rice-and-mugwort cake on Buddha's birthday, rice and adzuki-bean on the winter solstice and cake on Christmas and wedding anniversary. The results of the survey of perception of food traditions during the special events was as follows ; ‘annual events helped peoples to make relationships with family and relatives deeper’ showed the highest agreement. The willingness to pass on traditional foods for the special days showed the highest agreement on New Year's Day and Chusuk, followed by Ceremony of a forefather's death. the 15th of the first month, and finally the winter solstice.
