The purpose of this study was to investigate how educational experience (teaching experience, experience participating in the Teacher Learning Community, curriculum training experience, and innovative experience working in school) of elementary school teachers affects the recognition and execution of curriculum and textbooks. For this purpose, the results of a questionnaire survey for elementary school teachers were analyzed by performing T-tests, One-Way ANOVA, correlation analysis, and regression analysis. The results were as follows. First, according to the teacher's educational experience, there were statistically significant differences in the recognition and execution of curriculum reorganization, and the recognition and dependence on textbooks. Second, there were statistically significant correlations among such variables as recognition and implementation of curriculum reorganization, and the recognition and dependence on textbooks. Third, the teacher's educational experience had a significant impact on curriculum reorganization and the dependence on textbooks. Curriculum restructuring in elementary schools is not an end in itself. What is also needed is to find and implement the best class plans for promoting the .meaningful growth and development of elementary school students. This study suggests that the dependence on textbooks should be lowered and the curriculum should be actively reorganized, and teachers should develop their expertise based on extensive educational experience.

The book Su Hak Ip Mun(數學入門, Introduction to Mathematics) is one part of 5 sections of the book Seung Aeh Ill Chan(升厓日簒), which is a hand written manuscript in Chinese characters and the author and the date of writing is unknown. The book Seung Aeh Ill Chan begins with the song of division table so called Guguiga(九歸歌). We first investigate and compare the writing pattern of this with other old Korean mathematical books. Next, we investigate typical expression and calculation methods of mathematical contents and terminologies used in Su Hak Ip Mun and also figure out oddities of writing pattern of mathematical expression and cultural circumference of several problems dealt in the book. From these analysis and investigation, we estimate the writing date of Su Hak Ip Mun later than the year 1723 on which Su Ri Jeong On(數理精蘊) was first published. And we presumably guess that Guguiga and Su Hak Ip Mun are made not for practical use or theoretical purpose but for text to teach students.

This study examines how the patent results of the University Academic-Industrial Cooperation influence technology transfer. Statistical analysis was performed by using 2013 panel data from the Ministry of Education and Science Technology(MEST) National Research Foundation of Korea(NRF) and the results are as follows. The results show that the patent result factors that have a positive effect on the total number of technology transfers are domestic patent application numbers, foreign patent application numbers, future technology(6T) patent application numbers, science technology patent application numbers. The factors that have a positive effect on increasing royalty are the total number of technology transfers. Domestic patent application numbers, future technology(6T) patent application numbers and science technology patent application numbers have a positive effect on patent results. The results implicate that more research and development is needed for more patents to be applied, that the main focus should be on future technology(6T) and science technology fields, and that effort should be directed at planning negotiation strategies for the term of the contract. However, this study is the need to research, including primary research is so patent performance may be limited in having only been considered in future studies of human and material resources and operating system factors that may be presented to the essential elements of the Industry-Academic Cooperation Foundation this raises.

Small size ice-cream maker has two evaporators having different evaporating temperatures of $4^{\circ}C$ and $-8^{\circ}C$. In such case, ice-cream maker system design becomes complicated because multiple capillary tubes affects one another. In this study, performance analysis was conducted for the soft ice-cream maker having two evaporators operating at different temperatures. The compressor was analyzed using efficiency models, the capillary tube was modeled assuming one-dimensional flow, the condenser and the evaporators were modeld based on UA-LMTD method. The refrigeration cycle simulation program was developed applying the enthalpy, pressure and mass balance on each component. Comparison of the test data with the simulated results for R404A revealed that evaporator temperatures of refrigerator and freezer agreed within $3^{\circ}C$.

In this paper, we proposed planar spiral inductors based on AC coupling for high-frequency wireless signal transmission. Design and characteristics of various structures of the inductor were analyzed. Capacitance between the inductors can be reduced by positioning two thin-film inductors in parallel. So two structures were proposed. First structure is inter-diagonal structure. This structure was made not to overlap the wire part of the paralleled two inductors. Second structure is On-chip type structure that the two thin-film inductors were in parallel but located on diagonal line not to face each other. The resonance in this structure was reduced from twice to once by increasing horizontal distance between the two thin-film inductors, because the capacitance effect between the two thin-film inductors decreases when the distance between the two inductors increases.

With the ever increasing advances in computers and their computing power, computational fluid dynamics(CFD) has become an essential engineering tool in the design and analysis of engineering applications. Accordingly, many universities have developed and implemented a course on CFD for undergraduate students. On the other hand, many professors have used industrial examples supplied by computational analysis software companies as CFD examples. This makes many students think of CFD as difficult and confusing. This paper presents a simple CFD example used in the department of mechanical design engineering of Kangwon National University and shows its effectiveness. Most students answered that a simple CFD example is more comprehensive than an industrial example. Therefore, it is necessary to develop simple computational analysis problems in the engineering education field.

This paper focuses on detecting abnormal patterns of respiration of humans. In this study, a contact-based device was used to acquire both normal and abnormal respiration signals. To this end, this paper reports the development of a monitoring system to investigate the respiratory status of humans in a normal environment. This work aims to classify the respiratory status, i.e., normal and abnormal status, quantitatively. The respiration signal is acquired using a contact-based medical device (BIOBPAC), and noise reduction is carried out before classifying the respiratory status. To reduce noise, a mixed filter that combines the Savitzky-Golay filter and Median filter is applied to the acquired respiration signals. The inter-class distance is maximized, and the intra-class distance is minimized. The proposed algorithm is straightforward and can be applied to a practical environment. In addition, the experimental results are provided to substantiate the proposed approach.

This paper provides a critical perspective in historic conservation with reference to Hanok (Korean Traditional Courtyard houses) built in central Taegu city, Korea. These Hanok houses began to emerge in the 1920s near the city castle during the Japanese occupation. The houses were shrewdly crafted into a small site in an urban context. Towards the end of 1980s, the demand for urban regeneration arose due to dilapidation of the timber structure and fire safety. Proposals were made to redevelop the areas, but they did not progress past this point. No attempts were made for conservation either and the urban fabric disintegrated continuously. The area is now largely unattended for conservation or redevelopment. This research intends to create an historic account of Hanok in an urban context for its enduring characteristics and historicity as charm and merit that deserve careful apprehension and conservation. This paper suggests that conservation not only serves to gentrify the cultural disruption of the early 20th century but also contributes towards urban regeneration.
