Teaching Software Engineering through Robotics

This paper presents a newly-developed robotics programming course and reports the initial results of software engineering education in robotics context. Robotics programming, as a multidisciplinary course, puts equal emphasis on software engineering and robotics. It teaches students proper software engineering -- in particular, modularity and documentation -- by having them implement four core robotics algorithms for an educational robot. To evaluate the effect of software engineering education in robotics context, we analyze pre- and post-class survey data and the four assignments our students completed for the course. The analysis suggests that the students acquired an understanding of software engineering techniques and principles

Unpacking the gendered process of international migration: the case of migrant women in South Korea

This study explores the `gendered' process of international migration in Asia. It proposes that gender is one of the principal analytical factors for theoretical conceptualisation in the study of international migration. The study examines the case of Korea, which has been transformed into one of the major labour receiving countries in Asia since the early 1990s, but which has received less attention in the English literature on migration. The aim of the study is to examine the process of international migration in the historical, social and political contexts of Korea, by way of the integration of theoretical analyses with a critical gendered lens. A theoretical framework for this study is based on the observation that theorising the multifaceted process of international migration - which takes place with various interrelated variables - requires multidisciplinary and multidimensional approaches. The study therefore analyses the social formation of the `gendered' process of international migration by looking closely at the three different migratory stages of women migrants: the migratory journey; employment; and settlement in the country of destination. The primary empirical data used in the study were collected during a six-month period of field research - between April and September 2005. Qualitative data were derived from in-depth interviews with 31 migrant women, as well as employers, government officials and NGO workers. Based on a feminist standpoint of the outsider-within, the study locates the lives of migrant women from the margin to centre of the analysis. The empirical study shows that migrant women are `outsiders' who exist `within' the very core of international migration system in which they are, nevertheless, marginalised and silenced. The study suggests that the ostensibly gender-neutral process of migration is gender specific, resulting in different migration experiences between women and men. Gendered and racialised social relationships of power are pervasive in the structure of international migration and state institutions. At the same time, the differently `sedimented' practices of women and men - who strategically draw on institutional rules and resources to facilitate migration - become institutionalised in a gendered way. This, in turn, influences the gendered process of international migration that is reproduced and transformed over time

A Study on the Teacher\u27s Role Focusing on Teacher Pupil Control : From the Observation of Public Elementary Schools in Korea

This article describes characteristic daily roles of two teachers controlling their classes at elementary schools in Korea. We analyzed the class records of the teachers at public elementary schools ""K"" and ""M"" in Seoul, Korea, to grasp the class program and the relationships that they manage. We found that the time control depended on the learning progress of tasks and textbooks. Relationships were controlled by establishing the teacher\u27s overwhelming authority over all the students and by maintaining a strong one-to-one emotional relationship with individual students. They also tried to create comparison consciousness and rivalry among the students to enhance efficiency and concentration on course work

Ginseng and Its Active Components Ginsenosides Inhibit Adipogenesis in 3T3-L1 Cells by Regulating MMP-2 and MMP-9

The growth and development of adipose tissue are believed to require adipogenesis, angiogenesis, and extracellular matrix remodeling. As our previous study revealed that ginseng reduces adipose tissue mass in part by decreasing matrix metalloproteinase (MMP) activity in obese mice, we hypothesized that adipogenesis can be inhibited by ginseng and its active components ginsenosides (GSs). Treatment of 3T3-L1 adipocytes with Korean red ginseng extract (GE) inhibited lipid accumulation and the expression of adipocyte-specific genes (PPARγ, C/EBPα, aP2, and leptin). GE decreased both the mRNA levels and activity of MMP-2 and MMP-9 in 3T3-L1 cells. These effects were further inhibited by total GSs (TGSs) and individual GSs. TGSs and individual GSs also significantly decreased MMP-2 and MMP-9 reporter gene activities in the presence of phorbol 12-myristate 13-acetate (PMA), the MMP inducer. Among the GSs, Rb1 most effectively inhibited MMP activity. In addition, PMA treatment attenuated the inhibitory actions of GE and GSs on adipogenesis. Moreover, GE and GSs reduced the expression of NF-κB and AP-1, the transcription factors of MMP-2 and MMP-9. These results demonstrate that ginseng, in particular GSs, effectively inhibits adipogenesis and that this process may be mediated in part through the suppression of MMP-2 and MMP-9. Thus, ginseng and GSs likely have therapeutic potential for controlling adipogenesis

Suggestion of new possibilities in approaching individual variability in appetite through constitutional typology: a pilot study

BACKGROUND: Appetite is intricately connected to eating behaviors and shows a high individual variability. In an attempt to approach the problem of gut hormone profiles, appetite, and eating behaviors at the individual level, we have adopted a constitutional typing system widely used in traditional East-Asian medicine, the Sasang constitutional typology, in order to determine the individual variations in appetite, eating behavior, and weight change. METHODS: This pilot study was designed to investigate the variability of appetite among individuals by tracking the gut hormone patterns across different constitutional types. Pre- and post-prandial concentrations of anorectic (peptide YY (PYY), glucagon-like peptide 1 (GLP-1)) and orexigenic (active ghrelin) gut hormones were measured in healthy, normal-weight (18.5 kg/m(2) ≤BMI <23 kg/m(2)) male subjects aged 20–35 (Soyang (SY) (n = 9), Taeeum (TE) (n = 9), and Soeum (SE) (n = 10) constitutional types). RESULTS: Significant differences were found only in the PYY concentrations across the three groups (p = 0.031). The PYY concentration peaked at 30-min post-prandial in the SE group and was significantly higher compared to the other two groups (p = 0.004). The GLP-1 concentration peaked at 15-min post-prandial in the SE group (not significant). The ghrelin levels at 30-min pre-prandial were relatively lower in the TE group compared to the other groups (not significant). CONCLUSIONS: In conclusion, although with weak statistical power, meaningful gut hormone patterns specific to each constitutional type were discovered in this pilot study, which could offer a new method of approaching the problem of appetite and eating behavior from the angle of individual variability in appetite

Teaching a Core CS Concept through Robotics

We implemented single-session workshops using the Thymio- II—a small, self-contained robot designed for young stu- dents, and VPL—a graphical software development envi- ronment based upon event handling. Our goal was to in- vestigate if the students could learn this core computer sci- ence concept while enjoying themselves in the robotics con- text. A visual questionnaire was developed based upon the combined Bloom and SOLO taxonomies, although it proved difficult to construct a questionnaire appropriate for young students. We found that—despite the short duration of the workshop—all but the youngest students achieved the cog- nitive level of Unistructural Understanding, while some stu- dents achieved higher levels of Unistructural Applying and Multistructural Understanding and Applying
