Few colleges offer remedial basic math courses for college freshmen who have not passed math placement tests or whose scholastic aptitude test score in mathematics is low. This research is aiming for the curriculum development of basic college mathematics and its effective implementation. First, an in depth statistical analysis on the basic math courses for universities in Seoul area has been done. Second, diagnostic test and longitudinal study have been carried out for one institute. Based on these, basic concepts and areas critical for the success of Calculus course are extracted. Standards and contents for the remedial math courses are suggested.

In this paper, we surveyed the attitudes of engineering students in 6 universities in Chungcheong area to mathematics by 5-scale degrees and performed a comparative analysis of the results. The results revealed a number of meaningful points which should be applied to college mathematic education. On the basis of the results of the analysis, we made the following suggestions; 1) It is necessary to pay much attention to the students who have insufficient math ability 2) Special teaching methods are required for Freshman engineering students 3) Practical teaching strategies should be developed for engineering students that are based on the research on their math background 4) We should develop more materials in the area of mathematical concept image 5) More attention should be paid to the relation between math concepts and engineering concepts. Besides the above suggestions, we proposed that more research about students' math background and attitudes should be conducted for more efficient college math education.

In the present paper, we prove common fixed point theorems for single-valued and set-valued occasionally weakly compatible mappings in Menger spaces. Our results improve and extend the results of Chen and Chang [Chi-Ming Chen and Tong-Huei Chang, Common fixed point theorems in Menger spaces, Int. J. Math. Math. Sci. 2006 (2006), Article ID 75931, Pages 1-15].

In this paper we prove common fixed point theorems for four mappings, under the condition of weakly compatible mappings in Menger spaces, without taking any function continuous. We improve results of [A common fixed point theorem for three mappings on Menger spaces. Math. Japan. 34 (1989), no. 6, 919-923], [On common fixed point theorems of compatible mappings in Menger spaces. Demonstratio Math. 31 (1998), no. 3, 537-546].

In this paper, we investigate the uniqueness problems of certain types of difference polynomials sharing a small function. The results of the paper improve and generalize the recent results due to H.P. Waghamore [Tbilisi Math. J. 11(2018), 1-13], P. Sahoo and B. Saha [App. Math. E-Notes. 16(2016), 33-44].

As the value of living a complete life has spread, the importance of elderly education as a part of continuing education is ever increasing. As much as the bodily health, the activity to prevent dementia or healthy brain is being emphasized, the math utilizing traditional material was suggested to devise the curriculum appropriate for the emotional/cognitive level of the elderly. This could induce interests of the elderly, and ultimately improved the concept of self-consciousness and self-esteem. Also, a plan for effective application of such 'silver math' should be prepared, and the execution of a fusion study for a medical approach of its effects is proposed.

Multivariate finite mixture model is becoming more and more popular in image processing. Performing image denoising from image patches to the whole image has been widely studied and applied. However, there remains a problem that the structure information is always ignored when transforming the patch into the vector form. In this paper, we study the operator which extracts patches from image and then transforms them to the vector form. Then, we find that some pixels which should be continuous in the image patches are discontinuous in the vector. Due to the poor anti-noise and the loss of structure information, we propose a new operator which may keep more information when extracting image patches. We compare the new operator with the old one by performing image denoising in Expected Patch Log Likelihood (EPLL) method, and we obtain better results in both visual effect and the value of PSNR.

Passive learning attitudes and lack of enthusiasm in a retailing math course is quite common and a significant number of students do express their frustrations and struggles by seeking extra help outside the classroom. In order to promote students' active participation in class and to improve their performance and overall satisfaction with the course, a modified team-based learning (TBL) method was implemented in a retailing math course in two consecutive semesters. Implementing TBL into a retailing math course would improve students' accountability for their own learning, increase student interactions and engagement, and develop teamwork and collaboration skills. The scores on the midterm and final tests indicated that students' performance improved especially for the students who scored below 80% on each test when TBL was implemented. Students' reflection on the TBL activities done in class throughout the semester indicated that these TBL activities help them solidify the concepts taught in class better. They were able to realize their own mistakes and other group members who got the question right helped them understand. To maximize the benefit of TBL, it is suggested to implement TBL within the flipped classroom. Further research is called for to evaluate the effect of TBL on long-term knowledge retention among college students.
