In this study, the positive thinking, academic self-efficacy, and school adjustment of freshman dental hygiene students were identified. The correlation between each variable was identified and the influencing factors were investigated. Data collection was conducted from October 1 to October 21, 2019 on 213 freshman dental hygiene students in Gyeonggi-do, Chungcheong-do, Jeolla-do, and Gyeongsang-do regions. According to the study, the significant influence of freshman dental hygiene students' school adjustment was in the order of academic self-efficacy, positive thinking, and career program experience, and the most influential factors were academic self-efficacy, and the regression model explained was 47.7%. Since this study has been investigated and conducted on some freshman dental hygiene students, there is a limit to generalizing the results, subsequent studies will require continuous study of various variables for positive thinking and academic self-efficiency to school adjustment. However, based on this study, it is meaningful that it can be used as data to supplement the prior study related to school adjustment, and by presenting factors related to the school adjustment of freshman dental hygiene students, it is thought that it became basic data that confirmed the necessity of developing the school adjustment program.

The vehicle license plate recognition (VLPR) system analyzes and monitors the speed of vehicles, theft of vehicles, the violation of traffic rules, illegal parking, etc., on the motorway. The VLPR consists of three major parts: license plate detection (LPD), license plate character segmentation (LPCS), and license plate character recognition (LPCR). This paper presents an efficient method for the LPCS and LPCR of Korean vehicle license plates (LPs). LP tilt adjustment is a very important process in LPCS. Radon transformation is used to correct the tilt adjustment of LP. The global threshold segmentation method is used for segmented LP characters from two different types of Korean LPs, which are a single row LP (SRLP) and double row LP (DRLP). The cross-correlation matching method is used for LPCR. Our experimental results show that the proposed methods for LPCS and LPCR can be easily implemented, and they achieved 99.35% and 99.85% segmentation and recognition accuracy rates, respectively for Korean LPs.

There are a lot of manholes such as for water supply, sewage, telecommunication cable, traffic sign, electricity supply, and rainwater, etc. Conventional manholes installed on a road are impossible to adjust height, so that they should be entirely excavated to reinstall or repair. This entire excavation of a manhole causes too much time-consuming work, waste of resources, and obstruction of traffic. In this study, in order to solve the above mentioned problems, a cover, outer and inner parts of a manhole are integrated by gear-shaped parts located between outer and inner parts of a manhole. Mechanical design is performed to determine dimension of gear-shaped parts by Taguchi orthogonal array table. Cast molds for a gear-shaped manhole are also manufactured.

The purpose of this study is to define the paths through which academic burnout and self-efficacy of middle school students affect school adjustment, verify the path model of each factor, and examine the mediator effects of self-efficacy. In line with this objective, the study conducted a survey on 713 third year students of 3 different middle schools in city G. The first finding of this study confirmed that the path coefficient and suitablility index were significant, indicating that the path model was also significant. Second, academic burnout had direct negative effects on self-efficacy and school adjustment, while self-efficacy has positive effects on school adjustment. Third, self-efficacy was confirmed to have meaningful mediator effects on academic burnout and school adjustment. Based on these findings, academic burnout caused by excessive demand for academic success on korean students has negative effects on school adjustment, but if self-efficacy is well developed as an individual factor, school maladjustment can be reduced. Thus this study confirmed that psychological factors, such as self-efficacy, are necessary in school adjustment. Future studies were suggested on the basis of this study's findings.

The study conducted an employment capability reinforcement program targeting health-related college students, and then carried out positive analysis to find out how satisfaction affects adjustment to college life and academic achievement. An employment capability reinforcement program was conducted which targeted health related majors at a university located in Cheongbuk, and information on satisfaction, adjustment to college life, and academic achievement was collected through a self-administered questionnaire. The analysis results revealed that the higher the satisfaction for the employment capability reinforcement program, the better the adjustment to college life, while increased adjustment to college life affected academic achievement. Although the employment capability reinforcement program had no direct relationship of influence to academic achievement, the study shows that it does lead to increased academic achievement by way of adjustment to college life, which ends up as a positive affect for future employment. Therefore, active efforts are necessary to revitalize employment related programs that suit the characteristics of each department in order to establish an environment for revitalizing employment and increasing adjustment to college life.

This paper proposes an enhanced object tracking algorithm to compensate the lack of temporal information in existing particle swarm optimization based object trackers using the trajectory of the target object. The proposed scheme also enables the tracking and documentation of the location of an online updated set of distractions. Based on the trajectories information and the distraction set, a rule based approach with adaptive parameters is utilized for occlusion detection and determination of the target position. Compare to existing algorithms, the proposed approach provides more comprehensive use of available information and does not require manual adjustment of threshold values. Moreover, an effective weight adjustment function is proposed to alleviate the diversity loss and pre-mature convergence problem in particle swarm optimization. The proposed weight function ensures particles to search thoroughly in the frame before convergence to an optimum solution. In the existence of multiple objects with similar feature composition, this algorithm is tested to significantly reduce convergence to nearby distractions compared to the other existing swarm intelligence based object trackers.

Recently, there are a lot of endeavor to implement a fuzzy theory to artificial neural network. Goh proposed the fuzzy single layer perceptron algorithm and advanced fuzzy perceptron based on the generalized delta rule to solve the XOR Problem and the classical Problem. However, it causes an increased amount of computation and some difficulties in application of the complicated image recognition. In this paper, we propose an enhanced fuzzy single layer Perceptron using the dynamic adjustment of threshold. This method is applied to the XOR problem, which used as the benchmark in the field of pattern recognition. The method is also applied to the recognition of digital image for image application. In a result of experiment, it does not always guarantee the convergence. However, the network show improved the learning time and has the high convergence rate.

This study tries to investigate the influence of parents' neglect on adolescents' school adjustment, and to prove the mediating effects of self-identity and life satisfaction on the relationship between two variables. Data from 5th year(2014) Korean Children and Youth Panel Study(KCYPS) on 2035 nation-wide second year middle school students was analyzed by utilizing Regression analysis and path analysis. Results of the analysis showed first, parents' neglect had a negative effect on adolescents' self-identity, life satisfaction, and school adjustment. Second, adolescents' school adjustment improved with their self-identity and life satisfaction included as mediating effects. Third, the effect of parents' neglect on adolescents' school adjustment was partly mediated by the effects of subject's self-identity and life satisfaction. Furthermore, the need for program development to enhance adolescents' self-identity, life satisfaction and school adjustment was suggested.
