Under a continuous manufacturing process, two dimension inspection system causes problems as blurring effect and low resolution and requires position calibration between frames. One dimension inspection system is, therefore, being researched as a substitution. In this paper, we implement mechanism of switching memory and processing data for reasonable one dimension inspection system. Redundant weft image and noise was suggested to be reduced by new method using modified morphological process and masked erosion process. From resulting image, line data and possible error information were obtained and constructed as a structure. Finally, error detecting algorithm was performed with this data structure. Processing time of error detecting was 0.625ms per line in applied system and experiment showed 94.7% of error detecting ability. This method is 20% faster in speed and 2.7% higher in error detecting ability comparing with the present method.

The purpose of this study is to analyze nursing students' proficiency with ST(Systems Thinking) approach concerning asthma patient nursing process. For this study, 20 nursing students created causality cognitive maps which were consisted of the contents of 'asthma nursing care'. The word association and causality cognitive map were used to estimate ability of the ST. As a result, the students failed to understand the nursing process with the ST approach, or alternatively they applied low level ST approach and had a lower understanding of it. The findings of this study suggest that the development of a ST-based nursing educational program in order for nursing students to improve their ST ability as well as knowledge integration for multidisciplinary practice.

This paper proposes an improvement of a QoS based routing protocol. The hierarchical source routing algorithm[4] was improved by including of the Crank-Back algorithm[2]. The Crank-Back capability is the ability to solve the problem of selecting the wrong route because of using unsynchronized routing information in the ingress router. In order to reduce time of reversing the call-setup process back to the ingress router, spare-route information is included with a call-setup packet. Spare-route information could be used by every router to find the next appropriated link itself when insufficient resource of the selected link was found. The proposed algorithm improves the performance of the source routing call-setup process significantly.

The research is to be aimed how much the practice education could have influence on the critical thinking, the ability to work out problems and the confidence of nursing process. In order to collect the result, 4 scenarios had been applied into 41 of nursing student from March to July in 2014 (total 12 weeks). First of all, in the case of the critical thinking, its score($3.41{\pm}.31$) after being educated was remarkably higher than before($3.25{\pm}.26$). There was also no difference regarding the total score of ability to solve problems & nursing process confidence. However, the knowledge about nursing process, the identification of the relation causes and linkage regarding nursing process step account is after being educated were higher than before in subcategory. Although the changes regarding the ability to solve problems could not be identified with comparing before, the critical thinking and the confidence had been effected by the practice education with using the simulation. Thus, in order to identify the effect of the simulation education for further details, the more researches with the diversified subjects and the varied duration should be needed.

In the process of establishing the principle of genetics, Mendel discovered problems based on various observations. Mendel's scientific thinking ability can be effective if this ability is embedded in gifted science education programs. The study aims to develop a science gifted education program utilizing Mendel's scientific thinking ability shown in the principles of genetics and examine students' changes in scientific thinking ability before and after the program implementation. For the program development, first, the characteristics of Mendel's scientific thinking ability in the process of establishing the principle of genetics were investigated and extracted the major elements of inquiry. Second, the science gifted education programs was developed by applying the inquiry elements from the Mendel's Law. The program was implemented with 19 students of $7^{th}$, $8^{th}$ graders who attend the science gifted education center affiliated with university during July 2011. The Mendel's scientific thinking ability was classified into induction, deduction, and integration. The elements of inquiry extracted from the Mendel's scientific thinking include making observation, puzzling observation, proposing causal questions, generating hypothesis, drawing inference, designing experiment, gathering and analyzing data, drawing conclusions, and making generalization. With applying these elements, the program was developed with four phases: $1^{st}$ - problem finding; $2^{nd}$ - hypothesis generating; $3^{rs}$ - hypothesis testing and $4^{th}$ - problem solving. After implementation, students' changes in scientific thinking ability were measured. The findings from the study are as follows: First, students' abilities of problem finding is significantly (p<.05) increased. Second, students' abilities of hypothesis generating is significantly (pp<.05) increased.

This study tried to find a way to increase major satisfaction to overcome the difficulties of college due to the recent decrease in the number of educated population. In particular, problem-solving ability and digital literacy, which are essential in the era of the 4th industrial revolution, were set as influencing factors and mediators and tried to verify them. Therefore, in order to find out the effect of problem-solving ability on major satisfaction and the mediating effect of digital literacy, a study was conducted targeting junior college secretarial majors. A total of 193 questionnaires were analyzed, and regression analysis was performed to verify the hypothesis, and bootstrapping was performed using the SPSS PROCESS macro model 4 to verify the significance of the mediating effect. The results of the study are as follows. First, it was found that problem-solving ability had a positive(+) effect on major satisfaction. Second, problem-solving ability was found to have a positive(+) effect on all four sub-factors of digital literacy. Third, as a result of analyzing the mediating effect of digital literacy in the relationship between problem-solving ability and major satisfaction, among the four sub-factors of digital literacy, information literacy, critical understanding, and information analysis ability completely mediated between problem-solving ability and major satisfaction. has been shown to be effective. On the other hand, the ability to comply with norms was found to have no mediating effect. In this study, it was verified that problem-solving ability affects major satisfaction, and it was found that it is necessary to make various efforts to cultivate problem-solving ability. In addition, based on these research results, suggestions for preparing practical measures to increase major satisfaction were suggested.
