  • This study analyzed activities in chemistry chapters of middle school science textbooks for the 2009 revised curriculum using 8 science practices. All the activities that students could experience inquiry were analyzed in this study. There were the most activities in 'Molecular motion and change of state' and the least activities in 'Heat and our life' of three textbooks. There were the most science practices in 'Features of substance' in two textbooks, but there were the least science practice in 'Heat and our life' of three textbooks. 'Investigation planning and performing', 'data analyzing and interpreting', and 'explanation composition and problem solution designing' were frequently included, but 'asking questions and defining issues' was not included at all. For 'Investigation planning and performing', 'data analyzing and interpreting', and 'explanation composition and problem solution designing', a variety of achievement goals were targeted while a few goals were frequently targeted. Two to four kinds of science practices were frequently included in an inquiry activity. There were few activity that includes over 5 different kinds of science practice.

  • In this study, we analyzed activities in life science chapters of middle school 'science' textbooks for the 2009 revised Korea national curriculum and examined the difference between the analysis based on scientific practices and the analysis based on inquiry skills. As a results, there was a lot of inquiry skills in the order of 'reasoning', 'observing', 'classification' in the all of grade. In scientific practices, 'data analysis and interpretation' and 'constructing explanations and devising problem solving' were biased. This shows that life science inquiry activities in middle school 'science' textbooks are lacking in diversity in scientific practice elements as well as inquiry skills, and that the goals of the activities are limited. In addition, through the interrelationships between scientific inquiry skills and scientific practice elements, we examined contents relevance in the transition from inquiry function center to scientific practice, and compared with the results of inquiry activities in textbook, The results of this study were matched monotonously due to the tendency to basic inquiry-data interpretation / basic inquiry-explanation. This comes from results of the lack of diversity in activities presented in middle school 'science' textbooks. In this study, it is suggested that efforts should be made to include diverse scientific practice elements in the process of realizing 2015 revised Korea national curriculum from the simple and diversity-less inquiry activity through analyzing the textbooks of the 2009 revised Korea national curriculum.

  • BACKGROUND: It is essential to prioritize the exact and clear understanding of agricultural nonpoint source pollution (NPS) controls. The realistic policies and systems should also be developed based on this understanding. Therefore, this study aimed to present agricultural Best Management Practices (BMPs) applicable for the fields based on the Delphi survey result. METHODS AND RESULTS: This study deduced the evaluation items to assess each BMP for agricultural NPS control and conducted the surveying using the Delphi method based on agricultural BMP experts. In addition, its on-the-spot application were evaluated. Considering its importance, technical, social and economic proprieties showed that political support was ranked first and followed by cost investment, labor investment, reduction effect and resident participation. The survey findings by agricultural BMP experts showed the good performance of on-the-spot application can be achieved from fertilization by soil testing, residue and green manure application and contour plowing which are applicable within a field. Agricultural BMPs, highly applicable for the fields, were the countermeasures that farmers who are the principal bodies of agricultural NPS control could be participated directly. CONCLUSION: The active participation of farmers is essential for effective control of agricultural NPS. It is necessary to establish various incentive systems.

  • The agricultural policy/Environmental eXtender (APEX) model was developed by the Blackland Research and Extension Center in Temple, Texas. APEX is a flexible and dynamic tool that is capable of simulating a wide array of management practices, cropping systems, and other land uses across a broad range of agricultural landscapes, including whole farms and small watersheds. The model can be configured for novel land management strategies, such as filter strip impacts on pollutant losses from upslope crop fields, vegetated grassed waterways in combination with filter strip impacts, and land application of manure removed from livestock feedlots or waste storage ponds. The APEX model has continually evolved since its inception, and the process of adaptation and modification will likely continue as use of the model expands for an ever-increasing range of environmental problems and conditions. Several improvements to specific model subroutines have already been initiated, while other potential improvements have been identified that will require future research and code modification efforts.

  • This study aims to explore how teachers construct scientific explanation during instructional practices to help students' scientific inquiry. Before investigating teachers' classroom practices, elementary school science curriculum was examined to identify scientific concepts, particularly in earth science. Then, a total of six teachers' scientific explanation in actual teaching practices was analysed focusing on a) explanation of scientific concepts; b) rationale for scientific explanation; c) connection between scientific explanation and everyday explanation. The findings are as follows. First, the science curriculum provides $1{\sim}2$ main scientific concepts per unit, which are mostly appeared in the unit title. Those concepts and sub-concepts are not explicitly described but embedded in students' inquiry activities. Second, the teachers explain scientific concepts and discuss the rationale behind the scientific explanation, but rarely connect scientific explanation to everyday explanation. Also, the level of scientific explanations is low remaining level 1 or 2, not reaching 3, the highest level. Based on the results, the study suggests a) teachers need to provide explicit and clear explanations about scientific concepts; b) teachers are required to connect scientific explanation and everyday explanation; c) the level of teachers scientific explanation should be elevated by using an evidence, reasoning and claim, the components of scientific explanation as well as introducing new scientific concepts and inquiry activities.

  • 1. Need for and Purpose of the Study. There is an increasing demand for curriculum improvement of the Korean Army Nursing Academy (KANA), since it was upgraded into 4-year institution of higher learning from 3-year one. In particular, it is strongly advocated that the KANA needs the outside expertise for its curriculum improvement-namely not only from the internal military view of points but also from the viewpoints of professional educational society, In line with such a necessity for the study, this study was aimed at 1) analyzing the current actual practices of KANA'S curriculum, 2) investigating the desired practices of KANA'S curriculum, and 3) identifying the discrepancy between the actual and desired practices of curriculum. 2. Problems for the Study This study had 4 problems to be answeared as follows: 1) What are the actual curriculum practices of KANA? 2) What are the desired curriculum practices of KANA? 3) How are the extents of perception of actual and desired curriculum different in four groups (student, faculty & administrator, nurse, and medical doctor in militay hospital) ? 4) What are the restraining forces that impede the change from actual to desired curriculum practices? 5) What are the relationships of curriculum component,』 in actual and desired curriculum practices? 3. Methods and Procedures This study was conducted by means of document analysis in addition to literature review and by means of needs assessment questionnaire which was developed by the researcher. The questionnaire included 62 statments with 7 questions for demographic data collection. The needs assessment questionnaire was managed to a total of 243 subjects (100 students, 46 faculty & administrators, 55 nurses, and 42 medical doctors), The collected data were treated using SPSS computer system so as to calculate mean scores, standard deviations, and correlation coefficients. The significance test was made through t-test and one-way ANOVA. The statistical significance level was set at both .05 and .01 level. 4. Major findings The major findings in this study are as follows: 1) The score of desired practices was significantly greater than that of actual practices, representing a strong need for curriculum betterment. 2) There were significant differences in the perceptions of actual practices as well as desired practices among four groups (student, faculty & administrater, nurse, and medical doctor). 3) The most frequently selected restraining forces were army's inherent character, economical limitation, and educational expertise limitations. 4) Such variables as sex, position attachment to the KANA and grade made a statistically significant effect on the perception of desired curriculum practice, while the variables like marrige, position, and military class made it on the perception of actual curriculum practice. 5) The coefficients among the curriculum components were lower in perception of the actual curriculum practices than those in the desired practices. 5. Conclusions The conclusions based on the major findings of this study are as follows: 1) The current curriculum development procedure of the KANA is not consistent with the theoretical frame of systematic development sarategy of curriculum. 2) There are wide conflicts among the groups who are supposed to participate in curriculnm development, concerning the actual and desired practices of KANN'S curriculum. 3) A great deal of need for curriculum improvement for the KANA is clearly felt, and in particular, in the process of teaching and learning. 4) Each component of curriculum is not intergrated into a whole development procedure, being segregated each other. 5) For better curriculum improvement, such restraining forces as financial and professional limitations should be eliminated. 6. Recommendations 1) For Further Research a. There is a need to replicate this study after in-depth statistical analysis of each item of need assessment questionnaire, and with more representative subjects. b. A study should be conducted which. has its focus on the analysis of restraining forces for the change from actual to desired curriculum practices of the KANA. 2) For KANA'S Curriculum Improvement a. There is a need to promote the professional expertise of the participants in curriculum development and the communication among them. b. It is desirable to establish an institution or section of administration, which is soley in charge of curriculum development. c. To better develop KANA's curriculum not only faculty and administrators but also students should be encouraged to participate in development process, while the military medical doctors' participation should be carefully considered.

  • Purpose - This study aims to explore and describe human resource management (HRM) in Nepalese organizations. Specifically, this study addresses three research questions: (a) what are the key human resource (HR) practices in Nepalese organizations?; (b) what are the major tasks and roles of HR departments in Nepalese organizations?; and (c) how is the status of the HR function expected to change within Nepalese organizations? Research design, data, and methodology - For this purpose, we implemented the Delphi method and developed an informed consensus among selected experts concerning the research questions. Results - The findings illustrate that organizations in Nepal adopt a wide range of HR practices commonly used in Western and developed countries. Simultaneously, some HR practices specific to the Nepalese context are also discovered. The experts' consensus on the future of HRM confirms that the evolution of the HR function to a strategic partner of management is evident in Nepalese organizations. Conclusions - Domestic as well as foreign organizations in Nepal try to create HRM systems that place them on a par with global companies. At the same time, they incorporate cultural features specific to Nepal to compete effectively in local markets. While there are few empirical studies describing HR practices in Nepal, this study contributes to broadening our understanding of the current and future status of HRM in Nepal.

  • Purpose: The aim of this study was to identify the relationship between nurses' knowledge of adverse drug reactions (ADR), attitudes, and monitoring practices and to establish an effective ADR reporting system and provide baseline data for its activation. Methods: The participants in this study were chosen by convenience sampling and included 182 nurses working at major general hospitals that operate a Regional Drug Safety Center. Data were collected from June 1 to 12, 2015 and analyzed using Cronbach's ${\alpha}$, descriptive statistics, independent t-test, one way ANOVA, Pearson correlation coefficient and stepwise regression with the SPSS program. Results: The nurses' average score for knowledge was 7.62 points, for attitude, 41.04 points and for monitoring practices, 34.22 points. ADR monitoring practices positively correlated with knowledge (r=.19, p=.011), attitude (r=.41, p<.001), drug performance competency (r=.54, p<.001), and drug education satisfaction (r=.54, p<.001). Drug performance competency, drug education satisfaction, and attitudes explained 42.0% of the ADR monitoring practices (Adj $R^2=.42$, F=43.95, p<.001). Conclusion: In order to facilitate and encourage nurses' voluntary monitoring practice of ADR, efforts must be made to create positive attitudes toward ADR, and to increase drug performance competency and drug education satisfaction.

  • Most countries have their own culture that presents different types of behaviour. The employees' specific ways of working, according to each country, influence its organisation, thus cultural differences have become an essential issue in operating management. Therefore, this study explored how the different cultures based on Hofstede's paradigm interact within the specific Korean context. This study examined how cultural related HRM practices were enacted in the Korean hotel industry, how the frameworks of Hofstede's model impact the employee outcomes, including the concept of organisational justice. This study followed a quantitative approach which relied on a positivist paradigm to evaluate the different HRM practices at hotel workplaces with the view of employees. This study gathered a survey on 601 hotel employees in the deluxe sector. The analysis of quantitative data was undertaken using SPSS version 23.0 software and AMOS 23.0 to achieve the research aim for the study. This study contributes new findings to the research literature. The results of this study showed how Confucianism also plays a predominant role in understanding Korean culture, more than the Hofstede's original four dimensions of culture.
