In this study, we investigated secondary school science teachers' actual and preferred types of assessment with focus on the purpose and the method of assessment. Participants were 92 secondary school science teachers. We developed a questionnaire asking science teachers about the types of assessment they have actually used and the preferred types of assessment for hypothetical situations that have been generally reported as the prototypical examples of constructivist assessment. The characteristics of the science teachers such as teaching career, experience on in-service training about assessment, and perspective toward constructivist assessment were also examined. The analysis of the actually implemented assessments in their responses revealed that most science teachers tended to aim at traditional purposes such as summative assessment, and that multiple-choice was the most prevailing assessment method followed by experiment, report, and essay. For hypothetical assessment situations, science teachers exhibited their preferences for various types of constructivist assessment methods, whereas their purposes of the assessment still remained to be traditional. The science teachers who have had a relatively constructivist perspective toward assessment showed a statistically significant preference for using formative assessment than their counterparts in the hypothetical assessment situations.

This study analyzed the correlation between adolescents' smartphone addiction as well as depression, self-esteem, and self-regulation based on QEEG (Quantitative Electroencephalogram) analysis. The study period was from March 19 to July 12, 2019, and the subjects were 76 students at P Middle School in Gyeonggi-do (normal group 47, risk group 29) who filled out a questionnaire and were subjected to quantitative EEG. The data analysis was performed via frequency analysis, independent t-test, correlation analysis, and path analysis of the IBM SPSS Statics 21.0 program. First, smartphone addiction had a positive correlation with depression. Second, smartphone addiction showed a negative correlation with self-esteem and α wave. Third, depression showed a negative correlation with self-esteem, which did not show a significant correlation with self-regulation. Fourth, depression was higher in the risk group than the normal group. For self-esteem, the normal group scored higher than the risk group. Self-regulation showed higher significant differences with the normal group than the risk group. Fifth, for α wave and SMR, the normal group scored higher than the risk group. Sixth, α waves had a negative effect on smartphone addiction. This study is meaningful in that it applied a brain science approach using quantitative analysis for objective evaluation of smartphone addiction.

Addicts pay more attention to addiction-related cues, such as substance or behavior. And increased attention to these cues is associated with craving. Methamphetamine is the most abused drug among domestic drug offenders, with continually increasing rates of recidivism. Of the total number of reported drug offenders in the last three years, 21.1 percent have been women. Even so, research on female drug offenders is inadequate, rendering policies and fundamental data for the development of psychotherapy programs insufficient. The present study intended to investigate whether female methamphetamine addicts displayed an attention bias towards drug cues. A dot probe task was conducted on 22 female methamphetamine addicts (addiction group) and 22 non-addicts (control group). The task allowed the correct response rates and correct reaction times of the participants to be calculated according to the positioning of the drug and neutral cues. The analysis results revealed that the control group displayed no difference in correct reaction rates and correct reaction times between the drug or neutral cues. While, the addiction group showed lower correct response rate and slower response time for drug cues in comparison to neutral cues. The results of this study are significant in that it identified the attention bias characteristics toward drug cues of female methamphetamine addicts who were disconnected from drugs.

The objective of this study was to investigate the quality characteristics of spirits derived from fruit using copper distillation equipment. First, optimal yeast strains were chosen through a fermentation test on raw materials (apples, mandarins and rowanberries). The normal fermentation condition for rowanberries observed at a rowanberry concentration of 8% during mashing included chaptalization with sugar to increase the alcohol content. During the mashing, fruits were fermented and distilled through one of three different types of distillation apparatuses (pot distiller, vacuum distiller, or multistage distiller made of copper). The results revealed that the type of apparatus used affects the content of alcohol and flavor components. The distilled spirits prepared through a copper multistage distiller had a much higher tendency to retain components of fruit aromas such as ethyl acetate and provided higher yields than spirits prepared with a pot distiller or vacuum distiller. Thus, the copper multistage distiller apparatus can be applied to positively influence the taste and flavor of fruit distilled spirits by enhancing fruit aromas, removing impurities such as sulfur components and enhancing yields.

This study aims to confirm the effect of government support on the capability of socially disadvantaged enterprises (SDBs) and to explain the opportunistic behavior of SDBs to acquire more external resources such as government support. By dividing government support into policies and procedures, the difference in influence on corporate ability is analyzed by clarifying government support, and the impact of corporate capability on opportunistic behavior is analyzed using the structural equation (SEM) to provide government support The purpose of this study is to present the policy direction, the necessity of procedural development of government support, and the preceding factors to avoid opportunistic behavior. As a result of analyzing 261 questionnaires targeting SDB executives and employees, the relationship between government support policy and corporate ability was rejected. It was found that the government support procedure had a positive (+) effect on corporate ability, and that corporate ability had a negative (-) effect on opportunistic behavior. The implication is that, among the two components of government support, only the government support procedure was found to be significant. There should be publicity and in-depth consideration of government support policies.

The purpose of this study was to identify factors influencing maladaptive perfectionism, self-leadership, and social support on nursing students' clinical practice stress. Participants were 150 nursing students who were enrolled at four universities in Chungcheongbukdo. Data were collected using questionnaire by from 03 to 30 November, 2022. The measurement tools consisted of the Almost Perfect Scale-Revised, Self Leadership Questionnaire-Revidsed, Scale of Social Support, and Clinical Practice Stress Scale-Revised. Results revealed that higher levels of maladaptive perfectionism were associated with increased clinical practice stress. Decreased self-leadership, satisfaction with nursing major, number of clinical practice in other regions, and social support was also associated with increased clinical practice stress. Findings indicate that specific characteristics such as maladaptive perfectionism and decrease of social support can lead to increase clinical practice stress. In this paper, we propose that active considerations for these psychological characteristics are important when reducing clinical practice stress for nursing students.

This study was conducted to confirm the relationship between perception of patient safety culture, critical thinking propensity, and practice of standard precaution among nurses in small and medium-sized hospitals. The research subjects were nurses from three small and medium-sized hospitals located in S City and C City who understood the purpose of the study and agreed to participate. The final study subjects were 158 nurses. The data were collected from January 5, 2020 to March 31, 2020, and descriptive statistics, t-test, one-way ANOVA, correlation, regression analysis, and Sobel test of the collected data were performed using SPSS/WIN26.0 Program. As a result of the study, nurses' practice of standard precaution showed a significant positive correlation with perception of patient safety culture (r=.524, p<.001) and critical thinking disposition (r=.471, p<.001). Critical thinking propensity was found to have a partial mediating effect in the relationship between perception of patient safety culture and practice of standard precaution. Based on the results of this study, repeated research can be conducted in the future, and can be used to develop and apply educational programs that can improve nurses' practice of standard precaution.

Ecological nature was independently established in cultural content before the industrial society. Cultural contents started to be distributed as products in the industrial society, and since then there has been the coexistence of ecological and anti-ecological nature. Despite this change, community-based festivals and performances as ecological cultural contents encompassing both the time before and after the industrial society are still transmitted in some agricultural and fishing villages in today's Korea. Based on this aspect, ecological cultural contents can be defined as cultural contents that is practiced in various ways for symbiotic relations between men, man and impersonal being, and further beings surrounding cultural contents as well as man and nature. A basic plan for ecological cultural contents would pursue the three following directions: first, establishing a symbiotic system of cultural contents to create synergic effects among elements; second, building a distribution structure of virtuous cycle for cultural contents by reinforcing the productive abilities of consumers and users; and finally, expanding the base of cultural contents to exercise ecological nature. The perception and development of this ecological cultural contents will propose practical acts to help the human society move forward to an environment-friendly future in today's situations where the Earth's self-purification mechanism has collapsed.

The objective of this study is to find out how strategic human resource management(SHRM) of a facility security firm affects its organizational culture and behaviors of its members. This study was executed in June 2010 with facility security officers(FSO) in four private security firms by using a judgment sampling technique. A total of 343 FSOs were used in final analysis. Coefficient of reliability(Cronbach's coefficient alpha) of the survey was 0.691. The conclusion was as follows: First, SHRM of facility security firms exert its influence on organizational culture. That is, promotion of education/training, compensation, making avid followers, and career development may facilitate settlement of hierarchical, development-oriented, agreement -based and rationality-oriented culture. Second, SHRM of security firms would affect organizational citizenship behaviors(OCB), i.e., the promotion of education/training, compensation, making avid followers, and career development would tend to enhance consideration for others and altruistic, participatory, conscientious and gentlemanly behaviors. On the other hand, if proper compensation is not made, above-mentioned behaviors would decrease. Third, organizational culture of security firms tends to affect OCB. That is, when hierarchical, development-oriented, agreement-based and rationality-oriented culture is settled, consideration for others, altruistic, participatory, conscientious and gentlemanly behaviors tends to be enhanced.

Agricultural extension service in Ethiopia was started in early 1950s with mandate of transferring local research outputs and technologies to farmers, and importing technologies and improved practices from abroad. Extension service provided in this early time was limited to areas surrounding the experiment stations. Since then, Ethiopian Agricultural extension service has passed through at least five stages: the land grant extension system, the Comprehensive Package Programs, the Minimum Package Projects, the Peasant Agricultural Development Program, and the Participatory Demonstration and Training Extension System (PADETS). The comprehensive package extension program was initially implemented in selected pilot areas and eventually to be scaled up to cover about 90% of the farming community within 15-20 years time. The program used demonstration plots managed by development agents and used to train farmers organized through various field days. However, since all of these programs were operational in only small areas, the vast majority of the country was out of their reach. Through Participatory Demonstration and Training Extension System, the extension service in Ethiopia has come under the spotlight and government debates and external reviews are putting additional scrutiny on the system. Despite this long history, the system is still in its infancy in terms of coverage, communication and institutional pluralism. Currently in Ethiopia the Agricultural extension is provided primarily by the public sector, operating in a decentralized manner through which extension is implemented at the district level. Therefore, the main focus of this paper is to scrutinize the past, the present and the future Agricultural extension system in Ethiopia.
