There are many factors that affect academic achievement, and the influences of those factors are also complex. Since the factors that influence mathematics academic achievement are constantly changing and developing, longitudinal studies to predict and analyze the growth of learners are needed. This study uses longitudinal data from 2014 (second year of middle school) to 2017 (second year of high school) of the Seoul Education Longitudibal Study, and divides it into groups with similar longitudinal patterns of change in mathematics academic achievement. The longitudinal change patterns and direct influence of mood and satisfaction were examined. As a result of the study, it was found that the mathematics academic achievement of the first group (1456 students, 68.3%) including the majority of students and the second group (677 students) of the top 31.7% had a direct influence on the mathematics class attitude. It was found that the mood and satisfaction of mathematics classes did not have a direct effect. In addition, the influence of mathematics class attitude on mathematics academic achievement was different according to the group. In addition, students in group 2 with high academic achievement in mathematics showed higher mathematics class attitude, mood, and satisfaction. In addition, the attitude, atmosphere, and satisfaction of mathematics classes were found to change continuously from the second year of middle school to the second year of high school, and the extent of the change was small.

This study examined how the explicit and implicit race attitudes differ according to age and gender from the developmental perspective in Korean elementary students. The study also investigated the efficacy of a multi-cultural education program on explicit and implicit attitude change in elementary school students. This thesis consists of two parts. In Study 1, elementary school students(first grade:117, fourth grade:117) completed Explicit Attitudes Rating Scales, Explicit Preference Test, and Child Implicit Association Tests (Korean-White/Korean-Black/ Korean-Southeast Asian IATs). The effects of age and gender on explicit and implicit attitudes toward Korean/White/Black/Southeast Asian were examined with two-way MANOVA. The results demonstrated that as age increases, in-group preference/out-group bias decrease on the explicit level. In contrast, on the implicit level, as age increases, in-group preference/out-group bias do not decrease. Rather, prejudiced attitudes toward blacks increase. Study 2 was performed to investigate the effect of a multi-cultural education program on explicit and implicit attitude change toward races in elementary school students. The program conveying an anti-bias message consists of three sessions, and the procedures are as follows; watching video clips, confirming contents and short discussion. Two classes in the program and two classes in comparative groups on the first and fourth grade of elementary school were assessed. The results showed that black preference significantly increased both in the first and the fourth grade elementary students on the explicit attitude level, but not on the implicit level. The theoretical and practical implications of these findings were discussed.

The aims of this study were to identify the effects on sexual role identity and sexual attitude of the A-V programed sexual education on Oct. 1. 1997 through Sep. 30, 2000. The program was focused on the formation of the desirable sexual activity, attitude and androgyny sexual role identity of the Korean adolescents, and that was the 25 minute VTR media "Our sexuality is healthful". This study was non equivalent post-test only quasi-experimental design, and the subjects were 530 middle school boys in Busan, Korea. After the manipulation, the change of sexual role identity and sexual attitude was analysed. Outcome measures were middle school boys′ sexual role identity toward KSRI on a seven-point Likert scale and sexual attitudes toward SAS on a five-point Likert scale. The data was analysed by SPSS WIN. The results were summarized as follows : 1) The experimental group who was exposed to the A-V media produced by the author showed the higher score of androgyny sexual role identity than the control group who didn′t watch the A-V program. 2) The experimental group showed the higher rate of the androgyny than the control group, On the other hand, their rate of the masculinity turned out to be lower than the latter group. 3) The experimental group didn′t show the difference of SAS score from the control group .In conclusion, "Our sexuality is Healthful" A-V program for sexual education brought about the significant change of sexual role identity of the middle school boys, but didn′t affect their attitude toward sexual activity.

Background : With the increase of cooperative practices (CP) between conventional western medicine and traditional Korean medicine, there have been lots of researches on the status of CP and the attitude of doctors. Objective : Since most of the research is cross-sectional, this study aims to figure out the changes in the attitude of doctors toward CP through systematic review. Method : Systematic literature searches were performed on several databases in Korea. They were categorized according to the respondents and question items and analyzed by the context of questions, similarity of respondents and measurement scale. And we analyzed the changes of response regarding to doctors' awareness and attitude to CP. Results : Thirteen survey studies including attitude of doctors toward CP were selected. These studies were conducted between 1997 and 2009 and the number of respondents of each study ranged from 20 to 702. There has been increasing awareness of CP among doctors ; however the positive responses on the necessity of CP has decreased. Regarding the type of illness effectively treated employing CP, there was a shift from neurovascular to musculoskeletal and immune diseases. Most of the studies listed different approaches to disease, prejudice of health care providers and inadequate legal system as major obstacles against CP. Conclusion : In spite of the increase of CP in the last 20 years, there has not been marked positive change in the doctors' attitude toward CP. To promote CP, it is required to confirm the effectiveness of CP through disease models and change the medical legislation policies on CP.

To address the problems caused by the strong coupling of an airbreathing hypersonic vehicle's airframe and propulsion to the integrated control system design, an integrated airframe-propulsion model is established, and the coupling characteristics between the aircraft and engine are analyzed. First, the airframe-propulsion integration model is established based on the typical nonlinear longitudinal dynamical model of an air-breathing hypersonic vehicle and the one-dimensional dual-mode scramjet model. Thrust, moment, angle of attack, altitude, and velocity are used as transfer variables between the aircraft model and the engine model. The one-dimensional scramjet model can accurately reflect the working state of the engine and provide data to support the coupling analysis. Second, owing to the static instability of the aircraft model, the linear quadratic regulator (LQR) controller of the aircraft is designed to ensure attitude stability and height tracking. Finally, the coupling relationship between the aircraft and the engine is revealed through simulation examples. The interaction between vehicle attitude and engine working condition is analyzed, and the influence of vehicle attitude on engine safety is considered. When the engine is in a critical working state, the attitude change of the aircraft will not affect the engine safety without considering coupling, whereas when coupling is considered, the attitude change of the aircraft may cause the engine unstart, which demonstrates the significance of considering coupling characteristics.

While prior work has conducted individuals' password security behavior, there is a relatively neglect to examine individuals' affect and feelings of password fatigue in password change context. Therefore, this study explicated individuals' affective response to the feelings of password fatigue by drawing on several theoretical lens. Survey data collected from 267 users were used to test the model using partial least square analysis. This study found that feelings of password fatigue positively affected the negative password fatigue-induced affect, and also both the feelings of password fatigue and the negative password fatigue-induced affect were negatively related to attitude toward changing passwords, which in turn, leads to the intention to change passwords. Furthermore, this study found that shadow work recognition negatively moderated the relationship between attitude and behavioral intention. This study could offer a new theoretical perspective to understand an individual's security behavior and provide empirical evidences for practitioners in charge of IT security in organizations.

Information Systems (IS) is an essential tool for any organizations. The last decade has seen an increasing body of knowledge on IS usage. Yet, IS often fails because of its misuse or non-use. In general, decisions regarding the selection of a system, which involve the evaluation of many IS vendors and an enormous initial investment, are made not through the consensus of employees but through the top-down decision making by top managers. In situations where the selected system does not satisfy the needs of the employees, the forced use of the selected IS will only result in their resistance to it. Many organizations have been either integrating dispersed legacy systems such as archipelago or adopting a new ERP (Enterprise Resource Planning) system to enhance employee efficiency. This study examines user resistance prior to the adoption of the selected IS or ERP system. As such, this study identifies the importance of managing organizational resistance that may appear in the pre-adoption context of an integrated IS or ERP system, explores key factors influencing user resistance, and investigates how prior experience with other integrated IS or ERP systems may change the relationship between the affecting factors and user resistance. This study focuses on organizational members' resistance and the affecting factors in the pre-adoption context of an integrated IS or ERP system rather than in the context of an ERP adoption itself or ERP post-adoption. Based on prior literature, this study proposes a research model that considers six key variables, including perceived benefit, system complexity, fitness with existing tasks, attitude toward change, the psychological reactance trait, and perceived IT competence. They are considered as independent variables affecting user resistance toward an integrated IS or ERP system. This study also introduces the concept of prior experience (i.e., whether a user has prior experience with an integrated IS or ERP system) as a moderating variable to examine the impact of perceived benefit and attitude toward change in user resistance. As such, we propose eight hypotheses with respect to the model. For the empirical validation of the hypotheses, we developed relevant instruments for each research variable based on prior literature and surveyed 95 professional researchers and the administrative staff of the Korea Photonics Technology Institute (KOPTI). We examined the organizational characteristics of KOPTI, the reasons behind their adoption of an ERP system, process changes caused by the introduction of the system, and employees' resistance/attitude toward the system at the time of the introduction. The results of the multiple regression analysis suggest that, among the six variables, perceived benefit, complexity, attitude toward change, and the psychological reactance trait significantly influence user resistance. These results further suggest that top management should manage the psychological states of their employees in order to minimize their resistance to the forced IS, even in the new system pre-adoption context. In addition, the moderating variable-prior experience was found to change the strength of the relationship between attitude toward change and system resistance. That is, the effect of attitude toward change in user resistance was significantly stronger in those with prior experience than those with no prior experience. This result implies that those with prior experience should be identified and provided with some type of attitude training or change management programs to minimize their resistance to the adoption of a system. This study contributes to the IS field by providing practical implications for IS practitioners. This study identifies system resistance stimuli of users, focusing on the pre-adoption context in a forced ERP system environment. We have empirically validated the proposed research model by examining several significant factors affecting user resistance against the adoption of an ERP system. In particular, we find a clear and significant role of the moderating variable, prior ERP usage experience, in the relationship between the affecting factors and user resistance. The results of the study suggest the importance of appropriately managing the factors that affect user resistance in organizations that plan to introduce a new ERP system or integrate legacy systems. Moreover, this study offers to practitioners several specific strategies (in particular, the categorization of users by their prior usage experience) for alleviating the resistant behaviors of users in the process of the ERP adoption before a system becomes available to them. Despite the valuable contributions of this study, there are also some limitations which will be discussed in this paper to make the study more complete and consistent.

Objectives: The purpose of this study suggests effective elementary school based smoking prevention education for preventing students from smoking, by examining and analysing a variety factors related to their knowledge and attitude on smoking. Pre-post quasi-experimental study was designed to analyze the effects of knowledge and attitude toward smoking of elementary school students. Methods: Data were collected by questionnaires from 135 students of the control group and 359 students of the experimental group in Korea, from June 4 to July 20, 2007. The reliabilities of instruments were adequate (Cronbach's alpha=.73-.79). Data were analyzed by t-test, $\chi2$-test and ANCOVA using SAS V8 program. Results: The results were as follows; 1. The ANCOVA models of the knowledge and attitude toward smoking were very significant to explain about education effects. 2. After the smoking prevention education, the smoking knowledge and attitude of the experimental group was significantly improved, whereas those of control group didn't. Smoking prevention education for elementary school students increased their level of smoking knowledge and desirable attitude. Conclusion: Therefore, it is necessary to give and develop a more effective program which is suitable to the subjects's needs and low grades before start smoking. Furthermore more various teaching methods such as VTR, lectures, role play and long term education program are need to be effective to change attitude and to improve the smoking knowledge.
