Internet ethics is one of liberal arts courses in a college. We also have taught this subject for a number of years. In order to effectively communicate to students the internet ethics course, we gave some demonstration practice lectures by taking advantage of internet ethics related videos. Since the latest video presentation and its discussion were performed, it was helpful for students to recognize the internet ethical issues and concerns. However, simply video watching is short in the view of students' learning outcome improvement, since each student just watches the content passively in a class. Thus, we assign small student group consisting of 3 people make a video on internet ethics topic. This team project based class methodology is effective to each student who actively participates in the class and understands the concept which they directly make a video. We confirmed that classroom students' understanding for internet ethics has been increased by a survey of the class attendees.

Around Tongyeong coasts which located in southern coast of Korea composed to the complex coastal line and scattered by small islands. It also has been distributed to a complicated bathymetric structure by several types of channels. This study carried to analyze the spatial characteristics of macrobenthic community and benthic environmental variance on sub-tidal area based on multivariate statistics tools. Sediment composition varied from muddy sand to mud, and along the channels, it composed to a heterogeneous bottoms mixed by shell fragment, cobbles and mud. Organic contents on the surface sediment varied 1.1-3.9%. Total of 272 species, $33,349\;ind./m^2$ of macrobenthos identified in all of sample area. Polychaetes also prevailed among the specimen. L. longifolia, P. pinnata dominated based on density. Considering on the biomass, echinoderm S. lacunosa, A. tricoides listed. Closer to the coastal area, the density and diversity were higher. Community structure based on cluster analysis was discriminated into three groups. Each group was also characterized by geographical state such as depth, sediment composition. In addition, when applied to the bathymetric data, the channel, which composed to the mixed sediment, made a role of limited factor which characterized to benthic community. Because the specimen around the channel have been affected on the diverse sediment mixture. Most of benthic studies in the southern coast of Korea focused to the condition of benthic organic pollution spatially, because along the coast, it also developed a aquaculture ground and industrial complex. But, as results, most of the area, it turn out the less polluted areas nevertheless similar environment situation. It supposed that benthic community affect to the bottom sediment composition by physical characteristics.

This study addresses the need to adopt teaching-learning approaches in physical therapy education that develop links between theory and clinical practice in a meaningful way. Problem-based learning (PBL) is presented as a useful way to educate physical therapy for the future. The essential characteristics of problem-based learning include: curricular organization around problems rather than disciplines; an integrated curriculum rather than one separated into clinical and theoretical components; and an inherent emphasis on cognitive skills as well as on knowledge. PBL as implemented in the health sciences, is an educational method in which the focus of learning is a small-group tutorial in which students work through health care scenarios. The goals of the health care scenarios are to provide a context for learning, to activate prior knowledge, to motivate students, and to stimulate discussion. Learning is student-centered rather than faculty-centered, and self-directed learning is emphasized. Whereas the former focuses on critical thinking and clinical judgement, the latter's emphasis is on clinical competency. The physical therapist (PT) program at Cheju Halla college is a partial integrated problem-based curriculum. The history and process of PBL in general and in the PT program are reviewed. Long-term advocates of PBL stress that it is the only known method for preparing future professionals to be able to adapt to change, learning how to reason critically, enabling a holistic approach to health.

Seomin has been used frequently in mass media and political discussion. However, who is Seomin, how to define Seomin, and whether Seomin and middle class are different has been rarely discussed. This study conducted both national level of survey and in-depth interviews and explored how to define Seomin and who respondents think as Seomin. The majority of respondents consider themselves as Seomin and that monthly income is the most important criteria to define Seomin. Seomin was considered as those who have high school education and 200~300(million won) monthly income, live in a rented house, and work as a small-scale self-employer, skilled laborer, and low level of white collar workers. Also, Seomin is a precarious group which can achieve upward or downward mobility and is located between low and middle class. Those who have Seomin identity tend to have pride in their social status and hope for upward mobility rather than depreciate their social status or envy the middle class. In order for Seomin to be able to achieve upward mobility and to maintain pride in current status, diverse social policies are needed. Further analyses on examining characteristics and policy needs of Seomin are needed.

This study has a purpose to devise an education program in relation to Gerontology and geriatrics applicable to Korean nurses through literature review and analysis of education programs utilized by the Geriatric Education Centers (GECs) of USA. Educational contents on gerontology and geriatrics are very diverse in precedent literatures. The education programs of GECs for health care personnel are equally very diverse. Among educational contents, subjects considered important are age-related changes, health problems of the aged, pharmacology, death, fall and osteoporosis, delirium, dementia, depression, urinary incontinence, communication with elderly. Methods used in education program are mainly seminar, workshop and lecture through internet. In addition, case study, small-group discussion and conference are also adopted. The program proposed in this study for nurses in relation to gerontology and geriatrics consists of 32 hours' education; 6 hours for age-related changes, 10 hours for health problems of the elderly, 14 hours for health problems in old age and 2 hours of communication technique. Educational method proposed is to utilize lecture through internet, direct education, workshop, practical exercise, case study and role play in parallel. This study proposed an education program on the basis of precedent literature and the program of GECs. Therefore, it is desirable to develop in the future more practical education program applicable to and required in practicing fields. Of course, this development needs to be based on nurses' educational needs by field in relation to gerontology and geriatrics.

In this paper, we introduce a modified Moore Method designed for the multivariable calculus course, and discuss about the effective teaching and learning method by observing the changes in the understanding of students' learning and the effects on students' learning in the class implemented by this modified Moore Method. This teaching experiment research was conducted with the 15 students who took the multivariable calculus course offered as a 3 week summer session in 2008 at H University. To guide the students' active preparation, stepwise course materials structured in the form of questions on the important mathematical notions were provided to the students in advance. We observed the process of the students' small-group collaborative learning activities and their presentations in the class, and analysed the students' class journals collected at the end of every lecture and the survey carried out at the end of the course. The analysis of these results show that the students have come to recognize that a deeper understanding of the subjects are possible through their active process of search and discovery, and the discussion among the peers and teaching each other allowed a variety of learning experiences and reflective thinking.

The lack of short baselines, referred to as the short-spacing problem (SSP), is a well-known limitation of the performance of radio interferometers, causing a reduction of the flux detected from source structure on large angular scales. The very large number of antennas operated in the Atacama Large Millimeter/sub-millimeter Array (ALMA) generates situations for which the impact of the SSP takes a complex form, not simply measurable by a single number, such as the maximal recoverable scale. In particular, extended antenna configurations, complemented by a small group of closeby antennas at the centre of the array, may result in a double-humped baseline distribution with a significant gap between the two groups. In such cases one should adopt as the effective maximal recoverable scale the one associated with the extended array and use only the central array to recover missing flux, as one would do with single dish or ACA (Atacama Compact Array) observations. The impact of the missing baselines can be very important and may easily be underestimated, or even overlooked. The present study uses ALMA archival data of the ²⁹SiO(8-7) line emission of the AGB star W Hydrae for a demonstration. A critical discussion of the reliability of the observations away from the star is presented together with comments of a broader scope. Properties of the circumstellar envelope of W Hya within ~15 au from the star, many of which are not mentioned in the published literature, are briefly described and compared with R Doradus, an AGB star having properties very similar to W Hya.

Although the development of scientific thinking is one of the significant goals in science education in schools, there is a lack of empirical research on how science teachers conceptualize scientific thinking. This study explored how four pre-service secondary-level science teachers conceptualized scientific thinking and elaborated their conceptions through peer discussions. Results involved each pre-service teacher's conceptual spectrum of scientific thinking and showed the process of elaboration in their conceptions about three crucial issues in small-group or larger discussions. Three issues related to scientific thinking included everyday vs. scientific thinking, the relationship between science knowledge and scientific thinking, and the relationship between logical systems and evidence. Implications for pre-service science teacher education were discussed, and further research was suggested based on the results of this study.

In this study, we classified the group model construction types in the actual classroom situation implementing the instructional strategy mixed with individual model construction and group model construction types. The purpose of this study is to analyze the information flow and the individual construction types of each group model construction type to obtain implications for model co-construction in a real classroom environment. A two-session class on sound propagation was carried out for thirty-three 8th grade students in Seoul. A total of 65 individual model construction and 16 group model construction processes were collected and analyzed. The group model construction types were classified as unchanged, enumerated, and elaborated. The unchanged type was found in 8 groups, the enumerated type in 3 groups, and the elaborated type in 5 groups. The isolated individual and independent construction (i.I) were found mostly in the unchanged group construction type (50.0%) and enumerated group construction type (54.5%). In the unchanged type, the radial shape of flow in which one student's information is transmitted to all the members of the group appeared. In the enumerated type, the starting point of the information flow was observed from two individuals. In the elaborated type, linear information flow appeared and both the second dissemination and reflective construction (2d.R) contributed to the group model construction (58.3%). This study suggests a viewpoint that enables to understand the process of complex model construction in an actual classroom context rather than in an ideal situation. The result of this study suggests the necessity of a modeling strategy considering the characteristics of Korean small group culture. It is expected that the discussion will progress through further studies.
