Various websites have been created due to the increased use of the Internet, and the number of documents distributed through these websites has increased proportionally. However, it is not easy to collect newly updated documents rapidly. Web crawling methods have been used to continuously collect and manage new documents, whereas existing crawling systems applying a single node demonstrate limited performances. Furthermore, crawlers applying distribution methods exhibit a problem related to effective node management for crawling. This study proposes an efficient distributed crawler through stepwise crawling node allocation, which identifies websites' properties and establishes crawling policies based on the properties identified to collect a large number of documents from multiple websites. The proposed crawler can calculate the number of documents included in a website, compare data collection time and the amount of data collected based on the number of nodes allocated to a specific website by repeatedly visiting the website, and automatically allocate the optimal number of nodes to each website for crawling. An experiment is conducted where the proposed and single-node methods are applied to 12 different websites; the experimental result indicates that the proposed crawler's data collection time decreased significantly compared with that of a single node crawler. This result is obtained because the proposed crawler applied data collection policies according to websites. Besides, it is confirmed that the work rate of the proposed model increased.

Purpose: This study examined the effects of guided imagery on stress, state anxiety, test anxiety and core basic nursing skill performance score of undergraduate nursing student. Methods: An equivalent control group pretest-posttest design was utilized. A total of 45 senior nursing students were randomly assigned to either an intervention group to receive guided imagery, or a control group (experimental group=23 students, control group=22 students). The guided imagery was provided via audio files to the intervention group for eight minutes, once a day for five days. The pretest was given before the intervention to measure variables for both groups, and the posttest was performed immediately afterward and three days after the intervention. Results: Significant differences were found between the two groups in stress ((F=4.94, p=.012), state anxiety (F=5.99, p=.005), and basic core nursing skill performance scores (Z=-2.45, p=.015). Conclusion: Guided imagery for nursing students has been identified as effective for stress, state anxiety, and basic core nursing skill performance scores. Guided imagery can be used as an effective intervention before performance tests. These study results can provide useful data for nursing education.

This study was performed to investigate Seoul undergraduate students' thoughts on funeral rites and sacrificial rituals as well as ritual foods. A total of 542 students offered answers that the importance of sacrificial rituals was connected to filial piety for the ancestor, the customs descended from the past, and the belief that descendents received fortunes. The students didn't know the funeral rites process, but acknowledged they needed to know funeral rites, and would perform their parents' sacrificial rituals. We also found that students whose hometowns were Gangwondo and Jejudo were familiar with sacrificial rituals foods as well as their preparation and cooking. Also, the older the students, the better they knew the funeral rites process, sacrificial rituals and ritual foods. There were great differences in sacrificial rituals according to parent and student religions. Buddhists knew the most about funeral rites and sacrificial rituals, followed by Roman Catholics and agnostics. Protestant Christians were not interested in sacrificial rituals. The funeral rites process and the handing down of sacrificial ritual foods had significant differences based on sibling number. The more brothers and sisters in a family, the more committed they were to performing their parents' sacrificial rituals and the higher their interest in sacrificial ritual foods.

Purpose: This study evaluates the level of cultural competence (CC) and educational needs for cultural competence in nursing (CCN) in undergraduate nursing students. Methods: A self-report instrument was used to measure CC and educational needs for CCN. Questionnaires were completed by 330 nursing students in three nursing colleges. Descriptive statistics, a t-test, an ANOVA, Pearson correlation analyses, and multiple regression were used to analyze the data. Results: The mean CC score was 2.99 and the mean CCN educational needs score was 7.1. CC positively correlated with educational needs for CCN. The regression model explained 36% of the variance in CC. Factors affecting CC were school grades, multicultural education experience, frequency of meeting foreigners, length of encounters with foreigners, foreign-language fluency, and degree of interest in multicultural nursing. Conclusion: To strengthen the CC of students, nursing educators should develop an educational program for CCN and incorporate CCN into nursing school curricula.

Purpose: The purpose of this study was to examine whether non-cognitive student attributes such as learning style and personality type affected academic performance in a flipped learning classroom of a pre-dental undergraduate science course. Methods: 'Biodiversity and Global Environment,' a 15-week, 3-credit course, was designed as a flipped class in Seoul National University School of Dentistry in 2017. Second-year pre-dental students were required to enroll in the course and to engage in online learning and in-class discussion. The Kolb's Learning Style Inventory and the Myers-Briggs Type Indicator were conducted to measure non-cognitive student factors. Independent samples t-test and multivariate regression analyses were used to examine the relationships between self-rated measurements and academic achievement. Results: More than half of the students enrolled in the flipped science course had an assimilator learning style (50%), followed by convergers (24%), accommodators (16%), and divergers (10%), and their personality types were dominated by the introverted, sensing, thinking, and judging types, respectively. Examining group differences using the t-test demonstrated a significant relationship between the diverger group and higher academic success. In particular, the multivariate regression analysis indicated that both thinking types and female students performed better in discussion than feeling types and male students. Conclusion: To operate the flipped learning classroom more effectively in medical and dental education, the instructor should carefully develop and apply a more tailored facilitation and relevant assessment by considering student learning styles and personality types.

Purpose: This study was undertaken to develop and test a mastery learning program of nursing skills for undergraduate nursing students. Methods: In this methodological study, first, the preliminary draft of a mastery learning program to provide training for nursing skills was developed based on Bloom's framework for mastery learning. Second, to test the developed program, a single-blinded, nonequivalent control group nonsynchronized study was conducted on 50 senior nursing students in a University selected by convenient sampling. Thirteen students were assigned to a control group; 13, 12, and 13 of them were assigned to intravenous therapy, transfusion, and patient transfer groups, respectively. The achievement levels and performance scores of the selected nursing skills were measured before and after the completion of the program in all the groups. Lastly, the final program was confirmed based on the results of the program testing. Results: Intravenous therapy, transfusion, and patient transfer were selected as essential nursing skills for the program based on the priorities rated by clinical instructors and staff nurses. The achievement levels of selected nursing skills were determined by Angoff scores. After participating in the program, the proportion of passers and performance scores of the nursing skills in the experimental groups were significantly higher than those in the control group. The final program was confirmed which included a diagnostic test, enrichment activities for the passers and three repetitions of corrective activities and formative assessments for non-passers. Conclusion: The results suggest that a mastery learning program for undergraduate students can lead to better improvement and performance of essential nursing skills.

The main objective of this study is to examine the required aptitudes for undergraduate students who want to join export-oriented Small & Medium Enterprises(SMEs). 178 Dataset from a survey of exporting firms in Gwangju, Korea, were used to analyze the study. The results of the study are as follows ; First, the most required aptitude is 'the capability related to build up human relationship'. So students should learn negotiation skills in the college. In addition to this, student also try to join informal club and cultivate teamwork capabilities. Second, finding out a job in export-oriented SMEs is needed to equip with problem-solving capabilities. To do it, students should learn various subjects related to trade theory. Additionally, having some certificates like 'international trade master' can be better. Third, communication capabilities including foreign language and international business skills will be also required for students who are preparing for joining export-oriented SMEs. However, capabilities related to information technology and basic statistic skills does not have statistically significant correlation to recruitment intention. As a result, students who have such above-mentioned four aptitudes may have better position to find out jobs in export-oriented SMEs.

Engineering methodology which is defined broadly as the various nontechnical knowledge such as design process and the personal skills such as creativity that an engineer must have to be a successful practitioner, is not sufficiently implemented in the present undergraduate engineering programs. A systematic design education model is proposed in this paper to teach the principles and art of engineering. First level design education is to introduce engineering process and cultivate student's creativity. Second one is to apply the knowledge of sciences, mathematics and engineering sciences to the solution of basic engineering problems. Third one is to solve a real-life problem.
