  • In the present paper, we obtain two Theorems connecting the unified fractional integral operators and the Laplace transform. Due to the presence of a general class of polynomials, the multivariable H-function and general functions ${\theta}$ and ${\phi}$ in the kernels of our operators, a large number of (new and known) interesting results involving simpler polynomials (which are special cases of a general class of polynomials) and special functions involving one or more variables (which are particular cases of the multivariable H-function) obtained by several authors and hitherto lying scattered in the literature follow as special cases of our findings. Thus the Theorems obtained by Srivastava et al. [9] follow as simple special cases of our findings.

  • The aim of the present work is to obtain the inverse Laplace transform of the product of the factors of the type $s^{-\rho}\prod\limit_{i=1}^{\tau}(s^{li}+{\alpha}_i)^{-{\sigma}i}$, a general class of polynomials an the multivariable H-function. The polynomials and the functions involved in our main formula as well as their arguments are quite general in nature. On account of the general nature of our main findings, the inverse Laplace transform of the product of a large variety of polynomials and numerous simple special functions involving one or more variables can be obtained as simple special cases of our main result. We give here exact references to the results of seven research papers that follow as simple special cases of our main result.

  • In special education, the operation of curriculum for students subject to special education is a role given to special teachers and integrated class teachers, and there are prior studies that many teachers experience difficulties in operating the curriculum. In this study, it was intended to find out the direction of special education courses and appropriate support measures for the operation of special education courses by exploring the experiences of special teachers and integrated class teachers, difficulties and suggestions in operating the curriculum. Participants in this study were special and integrated teachers with more than 15 years of experience, and all interviews were conducted in one-on-one in-depth interviews. After all the interviews have been prepared in full-length versions, the analysis has resulted in six major subjects and twelve subtopics; each teacher has different curriculum operations, difficulties in applying the curriculum, insufficient support systems, professional qualifications, and daily concerns of teachers in integrated classes. In the discussion, the direction of operation of special education courses for students and appropriate support measures for the operation of curriculum were discussed, and the limitations of research were presented and proposed.

  • An opportunity for dental students to come into contact with individuals with disabilities is insufficient. Therefore, prejudice and negative attitudes towards persons with disabilities persist. Working under the assumption that educating dental students regarding people with disabilities will bring about positive awareness, we conducted this study. We investigated the changes in the recognition of the issues and needs of people with disabilities before and after special care dentistry class of students of dental college that will include an experience in a dental clinic with a disabled person. Seventy-two Kyung Hee University School of Dentistry third-year dental students attended the special care dentistry class in one semester and they took the same survey was before and after the class. In the questionnaire, we used the disability factor scale (DFS) that Siller has proposed. The authoritarian virtuousness factor getting lower to a significant level after receiving an education. This means that after the education, the respondents realize that how hard to adapt the disabilities. After receiving an education, the rejection of intimacy factor score significantly get higher than before they took the class. This means that after the training, positive attitudes towards those with disabilities were better than those towards the opposite sex. We were able to confirm a positive change in the recognition for persons with disabilities through the special care dentistry class. Our study shows that educating dental students on the how to take care of individuals with disabilities can bring about a positive change in the attitudes students may have regarding them.

  • This study concentrates on investigating teaching methods with which students of a commercial high school, located in a rural district, can improve their attitude toward mathematics. To begin with, this study examines the causes which make the students take negative views against it through a survey of their current attitude toward mathematics; offers a special class for them to develop a positive attitude toward it: and then, figure out how much they change their academic attitude within the class and how much they improve their academic achievement as well. The results can be summarized as follows: First, the experimental groups showed terribly negative attitudes toward mathematics, and their academic achievements were very low compared with students of academic high schools nearby, Second, thanks to the special class given to improve their attitude toward mathematics, the experimental groups ended up taking a meaningful positive attitude toward it and developing their academic achievements in the subject. On the other hand, the controlled groups without any chance to receive special lessons remained unchanged. Therefore, it is indicated that a special lesson, properly provided, would play an important role to improve students' positive attitude toward mathematics and develop their basic academic achievements.

  • 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.

  • The purpose of this study is analysis of traditional noble houses style of Ha-Dong area in Kyeong-Nam. The sequence of this study is at first finding the list of survey object, and investigating of those houses, after than drawing the site and floor plan, and lately analysis the characters of inner and outer space of them. It required six months. The results of analysis of them are as follows. 1. The noble traditional houses in Ha-Dong are found eight samples which are not noticed in academic society. 2. The constructions of noble housing in late Period of Cho-sun Dynasty are divided in three parts as a general role. Its grade is similar in Ha-Dong. The number of traditional noble house of (old) volunteer class is two cases. The (new) rich-farmer class is four cases. And there are two cases of (long) authority class. 3. The type of site plan is based on Korean south area style which is the style of departed rectangular type. But outdoor spaces are divided in several space by many fence than other area. It is the special item of construction. 4. The special character of indoor space is the use of 'Gong-ru'. It is called similar space used in top of main entrance building of large building. But it is located in various space in Ha-dong. It is included in any space of Sarang-Che, An-Che, Are-Che. The traditional noble houses of Ha-Dong area have special spacial characters. For long time there space was developed based on local identity. And its characters was divided various classes. Thus Ha-Dong area is definite place of useful identified traditional culture.

  • Today though the word ginyoe(gisaeng) was remained as a historic relic but they were firmly existed about 40 years ago and ginyoe's number was about three million in Chosun it's almost near 0.5% of the total population of Chosun. To think that point the ginyoe's so-ciety was considered a special one in the his-tory of Korean woman. The ginyoe as a special social class were specialize in technical art such as dancing and prostitute. Although they were low class they were luxurious slaves whoses clothing was almost equal to that of royal family. They were the leaders of fashion in woman clothing that's because their role was entertainer, This study can be summarized as follows. First ginyoe and public woman's clothing codes were nearly same in koryo but tatally separated in chosun. I could find that was came from those day's moral sprit. Second ginyoe's clothing was not only have luxuriance like royal family but also have unique clothing codes for them. Though they are low class ginyoe could use upper class's clothing codes. But upper class women could'nt use ginyoe's clothing codes are vary various and have their own clothing codes. Third I analyzed ginyoe's clothing codes and then derived 6 ginyoe's clothing messages. They were symbol of wealth symbol of power symbol of occupational function symbol of sexual attraction symbol of social position symbol of freedom.

  • In this paper, we first establish an interesting theorem involving the $\bar{H}$-function introduced by Inayat-Hussain ([7], [8]). The convergence and existence condition, basic properties of this function were given by Buschman and Srivastava ([2]). Next, we obtain certain new integrals and an expansion formula by the application of our theorem. On account of the most general nature of the functions involved herein, our main findings are capable of yielding a large number of new, interesting and useful integrals, expansion formulae involving simple special functions and polynomials as their special cases. A known special case of our main theorem in also given ([11]).

  • By a change of variables we obtain new $y$-coordinates of elliptic curves. Utilizing these $y$-coordinates as meromorphic modular functions, together with the elliptic modular function, we generate the fields of meromorphic modular functions. Furthermore, by means of the special values of the $y$-coordinates, we construct the ray class fields over imaginary quadratic fields as well as normal bases of these ray class fields.
