  • In this research, we investigated the effect of three visual feedback conditions (direct viewing, one-monitor viewing, and tow-monitors viewing) on the task performance of human operator in teloperation task. The three different level of task difficulties under each concitions were performed by thirty-six subjects. The result of the experiments was analysed by the task difficulties, and the measurements of performance are the task completion time and the frequency of task errors. In a teleoperator, the participation of a human operator is always required, and the man-machine interface and the operator's abilities is an important issue. Recently, the different types of sensory feedback conditions(force, vision, sound, tactile, etc) for teleoperation is a very active research area in ergonomics. Among them, visual feedback conditon is an important sense that can provide the information of task environment. Therefore, the sufficient understandings and investigation for human ability under various visual feedback conditions is required to establish the efficient man-machine interface of teleoperation. The result showed that the visual feecback conditions and the level of task difficulties have a significant effect on the task performance. For three level of task difficulties, the task completion time was the shortest under the condition of direct viewing. The number of task errors under the conditions of direct viewing and two-monitors viewing were reduced by more than half compare to that of one-monitor viewing.

  • Government agencies have many difficulties for the information system development and operation. One of the difficulties is a budget estimation. Each government agency suggests individually different estimation for the personnel expenses and IT infrastructure adoption costs in the same field of informatization promotions. The other one is the operation costs are increased exponentially in every year[42, 51]. Those difficulties make government agencies can not help adopting SaaS. In fact, most of IT consulting company and government agencies already recognized a variety of SaaS advantages. The most typical SaaS's advantages are cost reduction, Software rapid development and deployment. However, once government agencies decide to adopt SaaS, they can not avoid many problems and difficulties. There is no information in a detailed item in a budget. In those kinds of situation, there is no choice whether government agencies accept SaaS provider's suggesting adoption costs or not. Thus, we provide a sheet of SaaS adoption cost estimation to government agencies. To know the cost factors, this study uses TCO(Total Cost of Ownership)'s criteria. To give a management point, this study uses Gartner's Application development Life Cycle. In this study, the integration check framework which is SaaS adoption cost estimation makes government agencies possible to establish a adequate budget.

  • This study analyzes the difficulties that student teachers, beginning teachers and experienced teachers face in the field of kindergarten, and urgent support requests. The total of participants was 372 of this number, 122 were student teachers, 118 were beginning teachers and 132 were experienced teachers. The results showed the difference in difficulties and the needed support requests among student teachers, beginning teachers and experienced teachers. Student teachers had the difficulty of time management, but beginning teachers and experienced teachers had trouble due to the nonexistence of assistant teachers. Student teachers required teaching strategies for starting relationships with children within responsibility. Beginning teachers and experienced teachers regarded the plan, practice, and evaluation of a program as the most needed support request. Collectively, the results revealed that expansion of the practice period is necessary for student teachers so that they can gain experience with children, parents, and the children's education institution with various opportunities as a learning course.

  • This study explored the effects of maternal ambivalence over emotional expressiveness (AEE) and mother-adolescent communication on adolescent depression (depressed affect, positive affect, somatic symptoms and activity inhibition, interpersonal difficulties). Data were taken from 233 middle school students (128 boys, 105 girls) and their mothers. Regression analyses showed varying gender differences in the relationships among these variables. Boys with high maternal AEE had lower positive affect, and higher depressive affect, somatic symptoms and activity inhibition, and interpersonal difficulties, whereas girls' moods were not influenced by maternal AEE. In addition, boys with problems in mother-dolescent communication exhibited lower positive affect, higher depressed affect and interpersonal difficulties, but open communication was not related to any depressive symptoms. The mother-adolescent communication type did not appear to be associated with depression in girls either. Both boys and girls both had less open communication and more problem communication with mothers experiencing high AEE. Problem communication with mothers partially mediated the relationship between maternal AEE and interpersonal difficulties in boys only. Examination of maternal ambivalence over emotional expressiveness provides a deeper context for our understanding of negative family communication patterns and the psychological consequences, especially in mother-adolescent boy dyads.

  • The purpose of this study is to understand a migrant women's married life. The study examined migrant Filipino women's married lives, motives for marriage and migration to Korea, and their married life experiences. The results showed that these women get married to Korean men in pursuit of an economically better life to support their family in the Philippines through marriage migration. As for Filipino women's perceived difficulties in married life, they indicated hardships with redrawing the boundaries of nationality, as well as their husbands' faults or bad habits which are different from what they expected before marriage. Other difficulties mentioned were the peculiar culture of living with parents-in-law, and general difficulties in married life. This study showed that marriage migration results not from external pressure or motives but ultimately from their own decision in a social and cultural context. It was also implicated that Korea's superior position to the Philippines in international economic power has an effect on family relations. The boundaries of nationality are redrawn according to their married life. In addition, it was revealed that the Korean born children of migrant mothers who divorce because of difficulties in married life are in a very poor situation as their national identity depends on their mother's future marriage relations.

  • Recently there has been increasing emphasis on pedagogical content knowledge (PCK) for fostering science teachers' teaching professionalism that needs to be done from teacher training courses systematically. We investigated what were the PCK factors considered in planning instruction and the difficulties encountered in implementing it by pre-service teachers. In this study, 26 sophomores at an university of education in Gyeonggi province were asked to perform teaching demonstrations using scientific instruction models. They were also requested to write reflective journals and interview. Analyses of the results revealed that many pre-service teachers considered the teaching strategies such as the instruction organization and implementation when planning instruction. They had also regard to the learners' cognitive affective aspects, whereas the pre-knowledge of them was not properly considered. Especially, the curriculum and assessment were almost disregarded. Most of the difficulties encountered in planning instruction and implementing it were appeared in terms of the teaching strategies. For example, they had difficulties in considering the characteristics of each stage presented by the instruction models when planning instruction and implementing it. The frequencies of the difficulties in implementing experiment were especially higher than those of the other PCK factors. Educational implications of these findings are discussed.

  • Unlike daily hassles or minor stressors, immigration is an intense life event that may cause excessive stress. In particular, immigrant parents find themselves in a more stressful situation in that they experience stresses caused by immigration and stresses caused by parenting at the same time. The purpose of this study is to develop and validate an Immigrant Parental Stress Inventory (IPSI), that objectively and comprehensively assesses the stress experienced by immigrant parents within the Korean context. Based on the Immigrant Parental Stress Inventory developed within the American context, preliminary items were refined through a literature review and the discussions of experts and immigrant parents and were empirically validated with a sample of 203 immigrant parents residing in Korea. Through exploratory and confirmatory factor analysis, six main factors were identified (Factor1 Difficulties in communication, Factor2 Financial difficulties, Factor3 Difficulties in social adjustment, Factor4 Social discrimination, Factor5 Lack of social resources, Factor6 Difficulties in parenting). The IPSI was shown to be a psychometrically sound instrument that is capable of measuring immigrant parental stress within the Korean context. Social service professionals and researchers studying or working with immigrant families could use the IPSI to examine immigrant parental stress.

  • The objectives of this study were to explore the difficulties of high school mathematics teachers while guiding students and to examine whether the perception of difficulties varied by gender, position, and work experience. This study randomly chose 36 mathematics teachers as participants and they were living in six cities or provinces in South Korea. The results showed that teachers experienced difficulties while guiding students, in student evaluation and teaching and learning methods, in the order of magnitude. There was no statistical difference by gender, position, and work experience. Unlike the results of previous studies suggesting that mathematics content knowledge and pedagogical knowledge would help students guide students, the results of this study revealed that they had relatively little impact on student guidance.

  • Nowadays, learning management systems (LMS) are an effective and efficient tool for providing students with a high-quality education. The current study examines the effect of different factors on the use of the blackboard application on mobile phones. The study selects four important factors after factor analysis, such as facilitating factor, performance factor, satisfaction factor, and difficulties factor. The data was collected through a structured questionnaire from 45 students as a sample in the college of business administration at Prince Sattam Bin Abdulaziz University. The study uses a logistic regression model to examine the empirical relationship between LMS adoption and different factors associated with blackboard adoption. The results show that 71 percent of the respondents are between the age of 18-20 years, and 100 percent of students have experience in using blackboard. The empirical results show that the satisfaction factor is positive and significant at the 10 percent level of significance and the difficulties factor is also positive and significant at the 1 percent level of significance. The results conclude that the students are satisfied with using the blackboard on mobile, nevertheless, the difficulties factor which is positive and significant shows that students are facing some difficulties in using the blackboard on their mobile.
