Portfolio are emerging as a prominent type of alternative assessment. Portfolio assessment is becoming increasingly clear that this method of collecting and evaluating student work over time has significant advantages over more conventional approaches to assessment. So the purposes of the study were to review the concepts and steps for planning and implementing portfolio assessment in engineering education. In education, portfolio can be defined as a purposeful, systematic, reflective process of collecting and evaluating student products to document progress toward the attaintment of learning targets. Four steps for planning and implementing portfolio assessment in engineering education were suggested as follows: 1) determine purpose 2) determine sources of content, 3) teacher evaluation of contents and student self-evaluation, 4) using of portfolio.

The paper aimed to analyze research trends and productivity, targeting papers published for the past 24 years in The Journal of Engineering Education Research, For the research trend analysis, the content analysis was conducted and research productivity of authors was investigated through Lotka's Law. The research subject were 897 papers published on The Journal of Engineering Education Research from 1998 to June 2021. Research findings are as follows. First, the pattern of writing showed that percentage of co-authors over 2 was higher than single author. Second, the authors were most likely to belong the university, followed by government agency, affiliated organization and Research institutes in universities. Third, the flow of records in giving paper showed that the number of continuants has decreased over time and only a few writers have presented their papers. Fourth, the analysis results on the research productivity discovered difference in actual figure and revised, theoretical one, which indicates that Lotka's Law was not applied to The Journal of Engineering Education Research. Based on findings as shown below, we suggested a series of plans to develop The Journal of Engineering Education Research and increase research productivity in future.

Recently, the number of multicultural families has significantly increased in Korea, and this trend creates a need to understand how successfully students from multicultural families achieve their mathematics learning. To understand and predict the changes in mathematics learning achievement of these students over time, we conducted in this study a latent growth mixture model analysis. The study findings show that the majority (92%) of the students from multicultural families experience a decrease in their mathematics achievement over time as their grade level goes up. It was found, in particular, that female students are likely to have lower initial achievements and rapid decline over time more than male students and that the decline over time was more severe for female students than their male counterparts. The findings of this study convey several implications on the how to support the students from multicultural families. First, the result of this study was different from the outcomes of previous studies that presented the income of the household and the education level of the students' parents as major factors that determine the academic achievement of the students from multicultural families. Furthermore, the study indicates the need for more research to identify variables related to the mathematical achievements of the students from multicultural families and the need to use these research findings to develop public support plans for the students from multicultural families.

This study was designed to investigate the knowledge of urinary incontinence and its affecting factors among women aged over 30 years in Korea, and to provide the basic data for the primary urinary incontinence management program through the community-based cross sectional study from May 7 to July 18, 2000. The subjects, who were able to understand the questionnaires and consented their participation in the study, consisted of 2183 women, aged over 30 up to 89 years, residing in Seoul, Kyongki$\cdot$Kangwon, Chungchong, YongNam, HoNam, Cheju provinces. It took about 20 to 30 minutes to fill up the questionnaires. The data were analyzed by multiple regression with using SAS program. The results were as follows ; 1. The overall reported knowledge of urinary incontinence was $5.21\pm3.05$(range 0-14). Over the half of the subjects gave the correct answer to 5 items which referred to effects, treatment and management of urinary incontinence. Among items associated with the cause, two items, such as 'many common over-the-counter medications can cause involuntary urine loss', and 'involuntary urine loss is caused by only one or two conditions', were less likely to be correctly answered. 2. Those who were younger, had more education, or had urinary incontinence, were more likely to provide correct answers. The above findings indicated that the education program and campaign of the urinary incontinence should be developed and operated for those who are elderly and have had less education.

Background: Given the long hours on the road involving multiple and interacting work stressors (i.e., delivery pressures, irregular shifts, ergonomic hazards), commercial drivers face a plethora of health and safety risks. Researchers goal was to determine whether and to what extent long-haul trucker work schedules influence sleep duration and quality. Methods: Survey and biometric data collected from male long-haul truck drivers at a major truckstop in central North Carolina over a six month period. Results: Daily hours worked (mean = 11 hours, 55 minutes) and frequency of working over government-mandated daily HOS regulations (23.8% "frequently or always") were statistically significant predictors of sleep duration. Miles driven per week (mean = 2,812.61), irregular daily hours worked (63.8%), and frequency of working over the daily hour limit (23.8% "frequently or always") were statistically significant predictors of sleep quality. Conclusion: Implications of findings suggest a comprehensive review of the regulations and operational conditions for commercial motor vehicle drivers be undertaken.

Purpose: The purpose of this study was to identify the clinical practice experiences of nursing students who completed the courses of nursing curricula in college. Method: The data was collected using a questionnaire with 191 task elements in 8 nursing standards specified by the Korean Nurses Association(2003), from December 2004 to January 2005. Three hundred thirty-three nursing students from five three-year and five four-year colleges of nursing were selected for respondents. Result: The nursing activities which over 70% of the students had performance experiences with were 23 items(12.04%) practiced frequently in clinical settings, simple, low in malpractice risk and noninvasive in characteristic. In addition, the nursing activities which under 30% of students had performance experiences with were 87 items(45.55%). The nursing activities which over 70% of students had only observation experiences with were 20 items(10.47%). Also, the nursing activities that over 30% of students didn't have any experiences with were 19 items(9.95%) not frequently seen in the clinical setting. Conclusion: It is concluded that the students are not fully qualified as the new nurses of the future. Therefore, every effort to develop a more effective clinical nursing education in school, clinical settings and in students themselves is needed.

In this study, using 16 ORA-IP (Ocean Reanalysis Intercomparison Project) data, we investigated spatial and temporal changes of net surface heat flux in the East Asian seas and presented a new ensemble net surface heat flux index. The ensemble net surface heat flux index is produced considering the data distribution and the standard deviation of each ORA-IP. From the correlation analysis with air temperature averaged over the Korean Peninsula, ensemble net heat flux around the Korea Strait shows the highest correlation (0.731) with a 3 month time lag. For the correlation study regarding precipitation over the Korean Peninsula, it also shows significant correlation especially in winter and spring seasons. Similar results are also found in comparison with climate indices (AO, PDO, and NINO3.4), but ensemble net surface heat flux data in winter season reveals the strongest correlation patterns especially with winter temperature and spring precipitation.

Endophytic fungi occupy inner plant tissues, which results in various interactions between the fungus and host. Studies on endophytic fungi have been conducted in Korea for over 30 years. This paper summarizes the published results of those studies. The endophytic fungi of approximately 132 plant species in Korea have been studied since the 1990s, resulting in over 118 publications. The host plants featured in these studies comprised 3 species of mosses, 34 species of woody plants, and 95 species of herbaceous plants. At the family level, the most studied plants were members of the Poaceae family, covering 18 species. Regionally, these studies were conducted throughout Korea, but over half of the studies were conducted in Gyeongsangbuk-do, Gangwon-do, and Chungcheongnam-do. Relatively few studies have been conducted in a metropolis such as Seoul. We confirmed 5 phyla, 16 classes, 49 orders, 135 families, 305 genera, and 855 taxa of endophytic fungi, excluding Incertae sedis, whose relationship with others are unknown. Most of the endophytic fungi belonged to Ascomycota (93.2%), and a few belonged to Basidiomycota (3.6%). Since the diversity of endophytic fungi differs depending on the host plant, plant tissue, and distribution region, future studies should be conducted on multiple host plants and in various regions. Future studies on endophytic fungi are expected to broaden, including genomics and taxonomic and ecological studies of secondary metabolites.

With deepening globalization, various problems happening all over the world have not been limited to a country any more, but have had an influence over neighboring countries and international community. To deal with these problems international cooperation is getting important. Thus, over the existing individual- and state-centered thought, the alternative education is required to teach how to make a sustainable society and what to do for living together. In particular, current students are asked to be equipped with proper knowledge and attitude since they are to live as a global citizen beyond the Korean citizen in globalized era. This study analyzes the status of development education in other countries and in Korea, and it also suggests the use of terminology, approach to teaching, educational contents, and last but not least how to link the regular school curriculum in elementary, middle, high school.

Let a finite group R act smoothly on a closed manifold M. We assume that R acts freely on M except a union of closed submanifolds with codimension at least two. Then, we show that there exists an isomorphism between equivariant topological complex vector bundles over M and nonequivariant topological complex vector orbibundles over the orbifold M/R. By using this, we can classify nonequivariant vector orbibundles over the orbifold especially when the manifold is two-sphere because we have classified equivariant topological complex vector bundles over two sphere under a compact Lie group (not necessarily effective) action in [6]. This classification of orbibundles conversely explains for one of two exceptional cases of [6].
