Put ($$^*$$) $$G[x,y]={\sum}\limits^{p+q=n}_{p,q=0}[-n]_{p+q}c_{p,q}x^py^q$$, where $[{\lambda}]_m$ is the Pocbhammer symbol and the $c_{p,q}$ are arbitrary constants. Making use of the specialized forms of some of his earlier results (see [8] and [9] the author derives here bilateral generating functions of the type ($$^{**}$$) $${\sum}\limits^{\infty}_{n=0}{\frac{[\lambda]_n}{n!}}_2F_1[\array{{\rho}-n,\;{\alpha};\\{\lambda}+{\rho};}x]\;G[y,z]t^n$$ where ${\alpha}$, ${\rho}$ and ${\lambda}$ are arbitrary complex numbers. In particular, it is shown that when G[y, z] is a double hypergeometric polynomial, the right-band member of ($^{**}$) belongs to a class of general triple hypergeometric functions introduced by the author [7]. An interesting special case of ($^{**}$) when ${\rho}=-m,\;m$ being a nonnegative integer, yields a class of bilateral generating functions for the Jacobi polynomials $\{P_n{^{{\alpha},{\beta}}}(x)\}$ in the form ($$^{***}$$) $${\sum\limits^{\infty}_{n=0}}\(\array{m+n\\n}\)P{^{({\alpha}-n,{\beta}-n)}_{m+n}(x)\;G[y,z]{\frac{t^n}{n!}}$$, which provides a unification of several known results. Further extensions of ($^{**}$) and ($^{***}$) with G[y, z] replaced by an analogous multiple sum $H\[y_1,{\cdots},y_m\]$ are also discussed.

The mechanical clock was designed and produced by students as a trial theme of PBL class. The limit of making time is three weeks and main material is limited to paper. Only a basic mechanism drawing is given. As the principle of mechanical clock is not complex and does not need the special knowledge of mechanical engineering, even lower grade student seems to understand enough. This subject can train the skill of knowledge composition, creativity and the problem-solving ability. After execution,the validity and performance as the theme of PBL class was evaluated. As a result, the following findings were obtained. The paper made mechanical clock could be produced in three weeks. And, by additional improvements of the product, the enough strength and stable movement were achieved. Students can learn that many kinds of knowledge through actual experiences of design and making were required in manufacturing the real products. The proposed PBL style class is suitable as an introduction and training subject for lower grade student in department of engineering.

The purpose of this study was to investigate the status of teacher's perception about the nutrition education of elementary schooL The results of this study were as follows. Most of the teachers responded that nutrition education necessitate in curriculum of elementary school, the main reason for necessity of nutrition education was for proper growth, they thought starting period of nutrition education was to begin when children are in a kindergarten and a infant home. The perception for a suitable person to teach the nutrition education showed dietician, parents, class teacher and a related teacher in oder and the time of that is a related class, as a spare time at everyday, a special activity time, and service a meal in order. Importances of the contents of a nutrition education were proper eating habits, growth and nutrition, a food hygiene and a disease in order. Problems of elementary students' nutrition were a unbalanced eating, a ingestion a processing and instant food too much, lack of table manner, fatness and a weak child in order. The most of expected effects through the nutrition education were a good table habits and manners, the way of a efficient nutrition education were a need of link with parents, a need of link the dietician. a teacher's class and training in order. The average score of nutrition knowledge was 6.3$\sim$6.9 out of 10 and teachers of Gwangju scored more higher on nutrition knowledge than teachers of Jeonnam, as they arranged a dietician was so.

This is an exploratory study to verify the impact of applying SNS to lecture on the professor trust and students achievement. The subject of the study is two groups which consist of SNS applied class and the group using legacy online class supporting system and the contents, material, activities of class are same. We verified the differences between two groups with the professor trust divided into 4 constructs such as intimacy, expertise, teaching ability, leadership based on the literature review and students achievement classified into midterm and final. The results shows that intimacy and final evaluation are statistically significant between two groups.

The purposes of this study was to identify the dimensions of salesperson's effort and to examine the effect of salesperson's effort on relationship quality and customer intent to relationship continuity of middle upper class older female customers. The subjects used for the study were 202 middle upper class older female customers over 55 years living in Seoul. Factor analysis, paired t-test, multiple regression analysis and path analysis were used for statistics analysis. The results of this study were as follows. First, 5 factors were identified for the dimensions of salesperson's effort in older female customer's perception: attentiveness/product competence/effective access/friendliness/ special treatment. The salesperson's effort perceived most importantly was friendliness. Second, the salesperson's effort perceived by customer had direct and indirect effects on customer intent to relationship continuity; indirect effect mediated by relationship quality was larger than the direct one. Relationship quality was proved to have a crucial role in customer intent to relationship continuity. The influences of dimensions of salesperson's effort were also investigated. The effective access affected considerably on customer intent to relationship continuity.

This study investigates historically difference by age of wig banishments that symbolize social-economic status from West Egypt era baroque age as qualitative study that use secondary bibliographic data, there is purpose. Conclusion of this study is as following. Because wig putting on that symbolize among several usages of wig putting on, socio-economic status until 17th century baroque age from ancient Egypt is been in fashion through privilege class lower classes as well as upper class wig putting on attain. Ancient wig putting on became measure that divide class because differ material of wig or one dimension, shape (style) and length became linear measure that it can aim wealth's emblem that putting on of long wave wig and whole wig that differ lust has many wig though was in fashion though whole wig and were in fashion arriving to Renaissance. That it becomes France clean fingernails' necessaries as Louis the 14th that ready crux of absolute authority establishment of France Court put wig from depilation to count 17 was clear socio-economic status etc. symbol measure inclination. Go without question status or position, wealth and churchman puts wig so that can know special sex of weapon of where the soldiers are belonged as well as put wig and wig putting on was parted according to job and lower classes participated in fashion of wig putting on. Wig putting on that become measure that symbolize job or status in this baroque age, position, wealth etc. gave absolute influence in wig fashion in 18th century.

We report the rehabilitation of Class II malocclusion with multiple teeth fracture due to trauma. A multidisciplinary team approach was necessary to treat patient's problems such as bone fracture, malocclusion, and multiple teeth fracture. Emergency conservative treatment, orthodontic treatment and prosthetic restoration successfully restored the occlusion. However, special considerations were needed along the orthodontic treatment process due to the unexpected complications such as ankylosis, root resorption and detection of additional teeth fractures.

We performed to explore the applicability of protocol to improve the curriculum literacy for special education pre-teachers. For this, protocol of Park et al (2018), which can be used in the educational field, was partially modified and applied to enhance the special education curriculum expertise of pre-teachers. The literacy protocol of the special education curriculum was applied as Protocols 1 and 2, and Protocol 1 was focused on adaptation the 2015 special education curriculum and understanding literacy. Protocol 2 consisted of reorganizing the subject level centering on the five subjects presented in the special education curriculum, and establishing an integrated theme setting and reorganization plan. We applied the research design during a total of 15 weeks of special education curriculum subjects. The class format was flipped learning (e.g, pre-video lectures, theory lectures (E-Sheets), and learner-led activities (W-Sheets) for each topic was carried out. We found that pre-teachers' thought that the academic achievement and satisfaction of students with disabilities could be increased by adaptation the curriculum. Pre-teachers reported that the experience of reorganizing each subject/intersection helped improve their literacy but found it difficult.

In this paper, we use the auxiliary principle technique to suggest and analyze a class of predictor-corrector methods for solving noncoercive mixed variational inequalities. The convergence of the proposed method requires only the partially relaxed strongly monotonicity. which is even weaker than the co-coercivity. As special cases, we obtain a number of new and known results for classical variational inequalities.

Based on the recently developed ABS algorithm for solving linear Diophantine equations, we present a special ABS algorithm for solving such equations which is effective in computation and storage, not requiring the computation of the greatest common divisor. A class of equations always solvable in integers is identified. Using this result, we discuss the ILP problem with upper and lower bounds on the variables.
