The purposes of this study were to understand what is physics teachers' perceptions of idealization and to explore their teaching experiences about idealization in their physics classes. In order to achieve these research purpose, we conducted in-depth interviews with ten Korean physics teachers. The interview data was transcribed and analyzed interpretively. The results are as follows: (1) Physics teachers are not familiar with the term of 'idealization' but they understand the meaning of idealization and ideal condition. (2) Physics teachers understand the necessity of explicit mentions of idealization and ideal conditions in physics classes. (3) Physic teachers adapt conceptions of idealization and ideal condition into their lectures, experimental classes and evaluation strategies. Thus, the results of this study can provide theocratical understanding of idealization. It will help develop teacher education programs and physics teaching strategies. This research also suggested follow-up research questions about idealization in the physics education field.

This study was intended to analyze the present condition and problems of education by examining the curriculum of departments relating to IT design in community colleges in the environment of IT that more rapidly grew than any other sector due to the development of information and communication and smart device, focusing on the actual condition. And it was intended to present a scheme for the improvement of IT design curriculum in community colleges in preparation for the surveyed industry demand in IT sector. First of all, this study attempted to check how IT designers' work changed according to the change of technology in industrial scene through a survey of job in IT industry and an analysis of IT industry trends. As a result, it was shown that the work of IT designers who had carried out web design work extended to mobile design, and school education also required mobile education according to the change of the times. Here, through task analysis, it was possible to find that web design and mobile design was not fundamentally entirely different, but was within the range where it was perfectly possible to carry out mobile design work if mobile environment and condition was understood and an education was given together with the existing curriculum.

For studying on the actual condition of the oral health control of the old there were invastigations on the Questions with the college of the old in Chonbuk as the central figure from June 1 to June 30, 1998 and the analyses about the frequency and the mutual relation through χ²-test. The results are as follow: 1. According to the result of the investigation into the actual condition about the oral health of the old, two times a day in the frequency of tooth brush per day was the highest at the rate of 50.35％, the use of dentifrice was 45.4％, and the exchanging time of tooth-brush after six months was the highest at the rate of 19.7％. And 96.1％ didn't use dental floss and 73.6％ didn't do scaling. It is thought that since 50％ used tooth sticks and match sticks we have to inform the old of the necessity of dental plague and period oral examination. 2. In oral health situation, it showed that the number of people who were very week was the highest at the rate of 37％ and there was the mutual relation between the use of tooth sticks and match sticks and present situation of oral health. And 54.93％ visited the dental clinic wethin a year, and 22.3％ among them made full denture. There was the mutual relation between the visit of dental clinic within a year and the consultation content and the number of people who teld that the consultation expense was very expensive was the higest at the rate of 27.8％ and 87％ didn't experience the oral education. So it is thought that we have to make an systematic education about the oral to the old and inform them of the necessity of oral health control. 3. We think it needs the establishment and plane of the systematic basis material and the oral education which is necessary in oral public industry for the dental preventive suitable to the characteristic of the old.

This study evaluates the thermal insulation and evaporative resistance of a waterproof and breathable garment system and determines the factors influencing its thermal performance. The experimental garments were composed of underwear (shirts with 100% wool and 100% polyester) and outerwear (jackets and pants with a vapor-permeable membrane and a vapor-impermeable membrane). Data on clothing insulation in a dry condition ($10^{\circ}C$) and a wet condition ($10^{\circ}C$, 40% R.H.), evaporative resistance ($34^{\circ}C$, 40% R.H., and $10^{\circ}C$, 40% R.H.), and microclimate vapor pressure were collected and analyzed. According to the results, the thermal insulation of the experimental garment system ranged 1.27~1.40 in the dry condition and 0.40~0.89 in the wet condition at $10^{\circ}C$. Evaporative resistance ranged $41{\sim}525m^2Pa/W$. A decrease in thermal insulation by wetting underwear ranged 31~67% in the cold condition ($10^{\circ}C$). The breathability of the outer garment influenced the decrease in thermal insulation by wetting. The type of underwear fiber influenced the decrease in thermal insulation only when it was used with breathable outerwear. The vapor-permeable outerwear sample with polyester underwear (P_Perm) showed a larger decrease in insulation than that with wool (W_Perm). The evaporative resistance of the vapor-permeable ensemble showed no effect of underwear in the warm condition ($34^{\circ}C$), but polyester underwear showed lower evaporative resistance than wool in the cold condition ($10^{\circ}C$). The vapor-impermeable ensemble showed no difference in evaporative resistance between polyester underwear and wool underwear in both conditions. Future research should consider various clothing ensemble combinations and environmental conditions and evaluate wear comfort by using human subjects.

Recently, The employment for the disabled vocational rehabilitation is to be a hot issue. and there is many of the proposal how to ways. But many of the disabled vocational rehabilitation is not employed and then, first of all, we have a survey about. The employment for the disabled vocational rehabilitation on chonan city of korea. And we got that. The side of company and the side of the disabled vocational rehabilitation have a many problem for the employ. and there is the need of education for employ. We want to propose to good idea good condition employment for the disabled vocational rehabilitation. With the relation program with employment and education for the disabled vocational rehabilitation, they get a good condition jog. This proposal is to be the base study for the disabled vocational rehabilitation with the employment. This study attempts to suggest developmental framework of employment innovation model to vitalize the disabled vocational rehabilitation.

As a generalization of fuzzy subsemigroups, the notion of ${\varepsilon}$-generalized fuzzy subsemigroups is introduced, and several properties are investigated. A condition for an ${\varepsilon}$-generalized fuzzy subsemigroup to be a fuzzy subsemigroup is considered. Characterizations of ${\varepsilon}$-generalized fuzzy subsemigroups are established, and we show that the intersection of two ${\varepsilon}$-generalized fuzzy subsemigroups is also an ${\varepsilon}$-generalized fuzzy subsemigroup. A condition for an ${\varepsilon}$-generalized fuzzy subsemigroup to be ${\varepsilon}$-fuzzy idempotent is discussed. Using a given ${\varepsilon}$-generalized fuzzy subsemigroup, a new ${\varepsilon}$-generalized fuzzy subsemigroup is constructed. Finally, the fuzzy extension of an ${\varepsilon}$-generalized fuzzy subsemigroup is considered.

This paper studies about reducing the complexity of ML detection in MIMO/V-blast system, based on MMSE and ZF linear detectors. Beforehand, the receiver detects the signal using the linear detector such as ZF or MMSE. Moreover, the next step is to assess whether the signal is reliable or not by verifying the reliability condition, if the latter is reliable then it is the output if not it has to be detected by the advanced detector until the reliability condition is verified.
