Entrepreneurship is recognized as an essential education in start-up education. However, domestic studies on entrepreneurship in developing countries are extremely rare. The purpose of this study is to compare the importance of entrepreneurship and the perception of implementation of Korean and Nepalese farmers, and to seek a start-up education strategy based on the results. As a result of the study, first, there was no difference in the importance of entrepreneurship in the 6th industry between two countries, but the degree of entrepreneurial spirit performance was high in Nepalese farmers. Second, in terms of the difference between the importance and execution of the 6th industry entrepreneurship, Korea had lower performance than importance in all factors, and Nepal had higher importance than implementation in innovation, initiative, cooperation, and networking capability. Third, in the difference between the importance and the degree of implementation in each country, the level of implementation was uniformly lower than that of importance in Korea, but the height of the Nepalese farmers was not uniform. The results of this study, which studied entrepreneurship in Korea and Nepal, contribute greatly in terms of promoting the national economy by creating new added values.

Purpose : The purpose of this study was to assess hospital nurses' knowledge, importance and performance in keeping nursing records. Methods: The research design was a descriptive study. The sample for this study was 186 nurses with at least one year of work experience at a hospital with more than 800 beds in Seoul. Knowledge was self-reported using the Nurse Charting Knowledge Scale. Importance and performance were rated on a 4-point scale of 26 items. Data were analyzed by SPSS 21.0 program and IPA. Results: This study showed significant results that knowledge, importance and performance for keeping record are related to each other. The importance and performance of nurse's records were relatively higher than the mean. In the IPA Matrix, there were 2 items requiring improvement, 13 items requiring maintenance, and 11 items with low priority. Conclusion: Therefore, awareness of the importance of record keeping and continuous education on nursing record knowledge should be provided so that nurses can improve their record keeping skills.

Random forests is a popular method that improves the instability and accuracy of decision trees by ensembles. In contrast to increasing the accuracy, the ease of interpretation is sacrificed; hence, to compensate for this, variable importance is provided. The variable importance indicates which variable plays a role more importantly in constructing the random forests. However, when a predictor is correlated with other predictors, the variable importance of the existing importance algorithm may be distorted. The downward bias of correlated predictors may reduce the importance of truly important predictors. We propose a new algorithm remedying the downward bias of correlated predictors. The performance of the proposed algorithm is demonstrated by the simulated data and illustrated by the real data.

Purpose: The current study investigated how clinical microbiology courses are conducted at the undergraduate nursing level in South Korea to identify the perceptions of clinical nurses regarding their knowledge and the clinical importance of microbiology and further assess their educational needs. Methods: Curricula presented on the websites of 202 undergraduate nursing institutions were reviewed. In addition, a survey assessing the knowledge and importance of clinical microbiology perceived by nurses was conducted online. A total of 150 nurses participated in the survey. Data were analyzed using descriptive statistics, correlation coefficients, t-tests, analysis of variance, Borich Needs Assessment Model, and Locus for Focus Model. Results: The results indicated that 90% of undergraduate nursing institutions offer clinical microbiology courses under various subject names. The perceived knowledge and importance of clinical microbiology were correlated; however, knowledge was consistently lower than the perceived importance of clinical biology among nurses. The structure and proliferation of novel viruses ranked highest in the educational needs of nurses based on both the Borich Needs Assessment Model and Locus for Focus Model. Conclusion: Based on the findings, this study suggests educational opportunities for clinical microbiology in hospital settings to reduce discrepancies between knowledge and the importance of clinical microbiology faced by nurses.

The study aimed to estimate the importance of job tasks, job training requirement and work satisfaction felt by dental hygienists to help dental hygienists work efficiently and effectively. A total of 142 dental hygienists working in dental hospitals located in J participated in the study. A SPSS 10.10 for Windows was used for statistical analysis. The statistical significance was defined as ${\alpha}$=.05. The results of the study are summarized as follows: 1. The mean score for the importance of job tasks was 4.09. The respondents considered dental clinic management and assistance to dentists the most important among their job descriptions showing the mean score of 4.44. The need for job training was 4.15 in average. The respondents wanted to have training on how to make a dental health insurance claim to receive payment other than any training with the mean score of 4.42. The work satisfaction of the respondents was 3.65 in average. The respondents were most satisfied with their work in dental assistance. 2. By the category of job tasks, the levels of importance of job tasks, job training requirement and work satisfaction were higher in plague removal with an ultrasonic scaler related to clinical oral prophylaxis, pit and fissure sealants related to preventive dental treatment and instruction in the correct usage of toothbrush related to public dental health education 3. In dealing with dental radiation machines, the radiation protection was considered the most important. While the training for periapical radiography was most needed, the respondents were satisfied with working in the same area. The levels of job importance, training requirement and work satisfaction were high in preventive dental care in the community performed in relation to the public dental health care. 4. In the dental health insurance claim category, the levels of importance of job task, training requirement and work satisfaction were higher in insurance claiming. The levels of job importance and training requirement were high in dental clinic management and assistance to dentists performed for preventive dental treatment. The work satisfaction was higher in maintaining medical chart records. The levels of job importance, training requirement and work satisfaction were higher in dental assistance in relation to dental protection. 5. There was significant relationship between the level of importance and work experience. Those with a longer period of work experience had higher levels of job importance in dental health insurance claim, dental clinic management and assistance to dentists and the overall task(pE0.05). 6. A significant relationship was observed between the need for job training in dental cleaning and preventive dental treatment and work experience. Those with more than 8 years of work experience demonstrated that job training is most needed(pE0.05). 7. The work satisfaction level was higher in the group with more than 8 years of work experience, compared with those in other work experience periods(pE0.05). 8. A positive correlation was seen between the level of importance and the need for job training among three variables.

Recently we extended the fuzzy model for rule based systems incorporating an importance factor for each rule. The model permits for both unrestricted as well as non-negative importance factors. We use this extended model to design a fuzzy rule based classifier system which uses both the firing strength of the rule and the importance factor to decide the class label. The effectiveness of the scheme is established using several data sets.
