The purpose of this study is to improve robotics education in public education. This study was conducted with 157 secondary school teachers regardless of their gender, age and majors. The results are as follows: First, 68.2% of the respondents (81.2% of the STEM(Science, Technology, Engineering, Mathematics)-related teachers) thought that robotics education should be included in public education because it will be a very important area in the future. Second, 73.3% of respondents (89.3% of the STEM-related teachers) agreed that robotics education will be worth teaching as a regular subject. The most important reason was that they thought the robots would be an excellent tool to initiate their class participation and increase their study motivation. Third, the results from this survey showed that the technology teachers would be the best suitable instructors for robotics education. Lastly, teachers felt a great deal of burden to teach robotics although they thought robotics education was necessary. In order to implement robotics education in public school, teachers think it is necessary to take professional training. In addition, teachers should be supported with the reduction in their workload along with sufficient fundings, educational robots such as LEGO MINDSTORMS, and newly designed teaching materials.

This article intends to examine the widespread assumption, which has been uncritically accepted, that Zermelo simply adopted Hilbert's axiomatic method in his axiomatization of set theory. What is essential in that shared axiomatic method? And, exactly when was it established? By philosophical reflection on these questions, we are to uncover how Zermelo's thought and Hilbert's thought on the axiomatic method were developed interacting each other. As a consequence, we will note the possibility that Zermelo, in his early as well as late thought, had views about the axiomatic method entirely different from that of Hilbert. Such a result must have far-reaching implications to the history of set theory and the axiomatic method, thereby to the philosophy of mathematics in general.

This study is to classify subjectification and the perceived health of the elderly according to Q-methodology and to provide basic materials for health promotion of the elderly. In this study, 28 elderly people residing in Seoul classified 33 selected statements in to 9 standards. The material taken from this process resulted in 4 types by the analysis using a PC QUANL program. Case 1 thought that religion was important for their health. Case 2 were go-getters they thought they felt healthy at work. Case 3 took a serious view of their relationships with other people. Case 4 centered around the couple, and thought it important to live with their life's companion.

The purpose of this study is to scrutinize forefathers' standpoint on architectural planning by peering into their literature. Dongkukyisangkukjib which contains works about daily life of Lee Gyu-Bo, a great writer in the middle of Koryo, reveals well people of Koryo' thought on architecture, if we have a interest in a building space. The book holds his general viewpoint on architecture and documents about the remarkable houses he and his friends visited. Then we can know, through it, general thought on architecture of the upper classes in those days. Lee Gyu-Bo considered a house the other self of its owner and connected buildings with personality of their owner. 0 architectural process and architectural planning, buildings were shown variously by reflecting owner's value on architecture. Unlike Chosun era, people of Koryo prefer unlimited thinking to form or order. Therefore in construction especially such as a pavilion, there were many experimental tries which reflected owners' thought. Particularly we could estimate people of Koryo' conception of architectural design through a work of Lee Gyu-Bo, Saryunjungky, a document about a pavilion carrying four wheels, which describes concretely contents of architectural planning such as a planning of space, module, and intention.

The purpose of this study was to investigate students' actual thinking processes during conceptual change about free fall. To do this, middle school students were made an interview designed based on a teaching model using thought experiment. From the study, it was found that strategy for generating cognitive conflict by suggesting opposite views was not effective. However, many students changed their prior conceptions when new explanatory hypothesis, which explained why heavy object and light object fall equally, was introduced. And finally, even though students realized that the changed idea did not accord with the real world, they could easily solve that problem by observing demonstration designed to show the effect of air resistance.

This study was intended for getting information on the job satisfaction and consciousness of 305 cooks working at deluxe hotels in Busan to improve culinary arts training and an efficient man power control program. The results were as follows. Most of the cooks were males(67.2%) and less than 40 years old(85.6%), 59.5% were cooks, 67.0% were graduated from college and 74.8% earned less than 1.5 million won in a month. 39.5% had not changed their workplace. The male cooks had transferred to some other workplace more than 2 times than female ones. The higher their age, job classification and monthly income were, the more frequently they transferred their workplace. The frequency of job transfer was the most significant factor in the age of $30{\sim}39$. 37.0% of the cooks were unsatisfied with their pay. They preferred the more highly ranked hotels(36.5%) and being independent(26.0%) if transferring workplace. They thought devotion was the most important factor for good cooks. They thought efforts, skills and human relationships were important for developing cooks. They answered pay suitable for their work was an important factor to improve the food enterprise. They thought Japanese and Korean cooking had the best prospect, and qualifications for a good cook were sincerity, efforts, careers and skills.

Hairdressers may be exposed to many chemicals from hair dye, permanent, shampoo, hair spray and so on. The study was conducted to evaluate occupational exposure to 8 chemicals (isopropanol, ethanol, xylene, toluene, ethylbenzene, acetone, ammonia and formaldehyde) for workers and levels of these materials in airborne of a hairdressing salon. Since compared to ACGIH TLVs these 8 chemicals were very low, it is thought that there has no problem to occupational exposure to these chemicals. Even if hairdressing salon is not enforced on Korean Standards for Indoor Air Quality, level of TOVC was thought to be below the standards. At the aspect of indoor air quality formaldehyde needs to be controlled in the future. The results imply that emission of isopropanol, ethanol, acetone and ammonia are related with hairdressing job, but emission of xylene, toluene and ehtylbenzene is more related with traditional indoor air pollution than hairdressing job. Sources of formaldehyde is thought to be little related with hairdressing job. HVAC system was a little effective on general ventilation.

This study has Performed to develop rehabilitation model for determination of optimal rehabilitation time on the Cast Iron Pipes (CIP) with diameter less than 300 mm in water pipeline network and to analysis the sensitivity on the rehabilitation times of developed model. In the result from the application of the field, the renovation time was faster about 10 years than the replacement time. Especially, as the difference between rehabilitation and replacement time on E-CIP was about from 3 to 5 years, and it was thought that the replacement was effective on E-CIP. To sensitivity analysis, the discount rate of coefficient was fixed at 0.08, and the values of initial year break rate(N($t_o$) and growth rate coefficient(A) were adjusted in values of 0.0009, 0.0018, 0.0027, and 0.05, 0.10, 0.15 respectively. When the values of N($t_o$) and A was increased, the results from the time of rehabilitation and replacement was faster It was thought that N($t_o$), 0.018 was reliable values on the applied pipeline through the result of the study. In case of A, the values of A above 0.1 was thought to be Proper.

In the society where contradiction of modernism in 20th century was vividly exposed and paradigm was being changed from text culture into visual culture according to the development of technology, Benjamin tried to practically suggest solutions for socio-historical problems he was facing. In contrast with Adorno who criticized cultural industry, Benjamin found out the possibility to overturn existing value order and innovate reality in mass art media having emerged according to the development of new technology. And such Utopian possibility appears in his thought on the early Disney animation even if it is fragmentary. This thesis reviews how Utopian possibility was realized in the early Disney animation, which had been thought by Benjamin.

The tempering system which is developed by this research which sees energy curtailment and from the environmental side which is essential for in hazard analysis critical control point. The tempering system with development experimented frozen pork and fish. As test result, frozen pork region was not thawed occurred plentifully. Like this the actual condition, the case of frozen fish is grind and the bulk and density uniformly was formed, the pork the density was dense and was thought with the fact that the temperature difference change is big. Also after tempering from measurement location center the temperature appeared substitutionally with the low-end thing. This central part of the frozene region is thought the impedance change appears few. To hereafter respects an impedance change is thought that has the necessity which will change the structure of tempering system.
