Objective: This study tried to find out if a teacher education program that supports professionalism for beginning child care teachers in toddler classes is effective in professionalism, self-respect, and efficacy in teaching. Methods: The study subjects were 40 beginning child care teachers in toddler classes teaching in day care centers in Seoul, Incheon, and Gwangmyeong Gyeonggi-do. They were divided into an experimental group (20 teachers) and a comparative group (20 teachers). The collected data were applied to the SPSS 22.0 program. To find homogeneity of the two groups, a t-test was conducted. To analyze an intergroup difference, ANCOVA was conducted in the way of setting a pre-test score as a covariate. Results: The experimental group which participated in the program showed more positive effects than the comparative group in terms of professionalism, self-respect, and efficacy in teaching. Conclusion/Implications: Based on the results of this study, the program is expected to be meaningful in the field of early childhood education, and to lay the foundation for beginning child care teachers in toddler classes to become experts in their field.

Self-efficacy has been extensively evaluated, but no studies have investigated the effect of self-efficacy on the self-reliance of women in poor-households economic productivity. This study analyzes self-efficacy as a personal factor, learning processes, and social support as an environmental factor towards the achievement of self-reliance in women from poor-households in productive economy businesses. Despite the dominant logic of this scheme, there is a need for field-based data regarding whether the variable really supports the sustainable empowerment of poor-households women. This study used the quantitative method through the survey technique. The samples of this study included 250 people collected from five regencies in Indonesia by using a multiple-stage random sampling. The data were analyzed with structural equation modeling. The results show that social support has a significant positive impact on the learning process; social support has a direct negative impact on self-efficacy. The learning process has a direct positive influence on self-efficacy, while social support has a non-significant impact on self-reliance. The learning process has a direct influence on self-reliance. Social support and the learning process both have significant positive impact on self-efficacy. Social support, learning process, and self-efficacy simultaneously have a positive impact on self-reliance in productive economic activities.

The current study investigated how academic stress, academic burnout, and academic self-efficacy relate to each other; in addition, this study examined the mediating effects of academic self-efficacy on the relationship between academic stress and academic burnout of Chinese adolescents. A total of 412 students attending third-grade from two different middle schools (ninth-grade in the United States) located in Jiading District of Shanghai participated in the final analysis. By using structural equation modeling (SEM) and the maximum likelihood estimation procedures of AMOS 20.0, the latent variable measurement models were confirmed. The results and conclusions of this study are summarized as follows. A positive correlation between academic stress and academic burnout was soundly supported by this study. Meanwhile, both academic stress and academic burnout indicated negative correlations with academic self-efficacy. The modeling indicated that academic self-efficacy has a partial mediating process and a direct effect on the relationship between academic stress and academic burnout. Thus, academic stress and academic burnout were significantly weaker when academic self-efficacy was higher. In the field of education and curriculum, these results are applicable for restructuring or developing Chinese middle school curriculum utilizing useful methods for adolescents to develop their academic self-efficacy.

This study investigated the effect of the 'Chemistry in everyday life' course for 234 pre-service elementary teachers on their beliefs regarding science teaching efficacy and the nature of science. This study also examined the effect of this particular course by their field (natural science, humanities & social science, and fine arts). The results show that after the semester the pre-service teachers' science teaching efficacy beliefs were enhanced. In particular, their personal science teaching efficacy beliefs were improved across all fields. However, their beliefs regarding the nature of science remained largely unchanged. This study discussed the implications surrounding science courses for pre-service teachers.

Whether This paper argues that teacher efficacy is an affective affiliate of pedagogical content knowledge (PCK) based on empirical data of a study on the nature and construct of PCK. This study was a collective case study utilizing qualitative research methods. The participants of the study were three high school science teachers in the U.S. Data was collected from multiple sources such as classroom observation, interviews, teachers' written reflection, students' work samples, and researchers' field notes. Data was analyzed using the "In-depth Analysis of Explicit PCK" developed by the author. Data analysis indicated that teacher efficacy played a critical role in developing PCK by facilitating the movement from PCK to the enactment of PCK.

The field control efficacy of entomopathogenic nematode, Steinernema carpocapsae Weiser, was evaluated on the beet armyworm, Spodoptera exigua (Hiibner). The insect pest has been known to be a defoliator at the aerial part of the crop and difficult to be controlled effectively with most commercial chemical insecticides due to its insecticide resistance. To overcome the susceptibility of the nematodes to desiccation when they were applied by leaf spray in field condition, we screened several commercial antidesiccants (alkyl glucoside, CMC, glycerol, Keltrol-F, Kunipia-G, and Laponite LXG) optimal for survival of the nematodes. Keltrol-F (0.1 %) was selected as a candidate supplement for field application of the nematodes. Leaf spray of the nematodes at 5,000 infective juveniles/ml of distilled water containing 0.1 % Keltrol-F resulted in 87.7% control efficacy on the 3rd instar larvae of Sp. exigua.

Oak wilt caused by Raffaelea quercus-mongolicae was first noticed in South Korea in 2004 and, ever since, its distribution and damage have been increasing. To screen a fungicide effective for oak wilt control by tree injection, laboratory and field experiments were conducted. Ten fungicides and one antibiotic were examined in vivo for their effectiveness in restricting the growth of R. quercus-mongolicae and R. quercivora (Japanese oak wilt pathogen) isolates. To the Korean isolates of R. quercus-mongolicae, chlorothalonil showed the highest fungicidal effects, followed by benomyl and propiconazole. To the Japanese one, propiconazole was highest in the fungicidal effectiveness, followed by benomyl and bitertanol. Propiconazole was selected for field-testing of its control efficacy because it showed good fungicidal effects in vitro and systemic activity. The control efficacy in the field was 87.5% in the first year of injection and 66.7% in the second year, indicating the fungicidal effects last at least over one year.

The efficacy of conidia of Beauveria bassiana (Balsamo) Vuillemin strain CS-1 that showed high mortality in laboratory and net house was examined against diamondback moth larvae in the field. Conidia ($4{\times}10^{7}$ conidia/ml) were applied to larvae on chinese cabbage in a 1.5% emulsifiable oil-emulsion amended with 4% clay at a volume of 0.55 L/3.3 $m^{2}$. There were no significant differences among plants and replicates in the deposition of spray droplets on water-sensitive papers or of conidia on leaves and larvae. Weather conditions were rainy and cool during first few days, and then hot and dry. Persistence of conidia was equally short on both leaves and larvae. Nevertheless, treatment of B. bassiana potentially reduced larval populations. But the field efficacy was lower than the laboratory efficacy. This reduced efficacy was ascribed to unfavorable environmental conditions.

The purpose of this study is to clarify the relationship between coaching and self-esteem, career decision-making self-efficacy, and career preparation behavior through field experiments. To accomplish the purpose of the study, as the purposeful sampling was selected 50 male university students in Chungnam, South Korea. This experimental design, 25 university students were assigned to an experimental group, and another 25 university students were assigned to a control group. The experimental group had four sessions of coaching program. The control group did not have any coaching sessions. After four coaching sessions, questionnaires were administrated again. To conduct ANCOVA, pre-measurement scores for each dependent variable were included as covariates and post-measurement scores were included as dependent variables. The result proved the effect of coaching on self-esteem, career decision-making self-efficacy, and career preparation behavior. As the results of analysis, for control group, there was no difference between before and after measurement for each dependent variable. However, there was statistically significant difference between before and after measurement for each dependent variable in experimental group. This result confirmed that coaching caused increase in the level of self-esteem, career decision-making self-efficacy, and career preparation behavior. The result like this has a significance to be able to be used as a basic data that used efficiently in the field of career guidance and HRD for university student.
