  • Inquiry became an essential methodology in science education. Recently, argumentation becomes more important in inquiry, but inquiry-based teaching in school science would not provide enough opportunities for students to have voluntary and active interactions during inquiry activities. Informal science learning can be an alternative for authentic inquiry. Accordingly, this study aims to find interaction patterns in dialogic inquiry of junior high school students in small groups in the natural history gallery. Inquiry elements and interaction patterns are analyzed with 42 dialogues of 13 small groups. As a result, seven interaction patterns are identified. First, five major interaction patterns were drawn as follows; Sharing questions, asking questions and simple response, asking questions and simple explanation, asking questions-simple explanation-(collecting data)-data based explanation, and asking questions-collecting data-data based explanation. Second, pattern 2, 'asking questions and simple response', is subdivided into three categories; passive and/or evasive response, inaccurate response, and repeated patterns of asking questions-simple response. The results of the study provide different patterns of dialogic interactions in a small group inquiry in informal contexts from formal contexts, and provide foundations to understand middle school students' interactive dialogues of inquiry occurred in the natural history gallery.

  • Purpose: This research was to determine the characteristics of dysmenorrhea among girls, identify the factors affecting dysmenorrhea. Method: The study subjects were 1653 high school student in Busan Metropolitan city. The data were collected by a self-administered questionnaire between November 1 and November 30, 2002. Descriptive statistics, t-test, one-way ANOVA with Scheffe' test, and stepwise multiple regression analysis in SPSS program were used for data analysis. Result: Students suffering from slight dysmenorrhea made up the majority 52.9%, whereas those with serious cases represented 29.8%. Regarding the measures taken to cope with dysmenorrhea, most of the respondents took analgesics 52.8%. A high points of dysmenorrhea was associated with irregular meal habits(p<0.01), unbalanced diet(p<0.05), stress(p<0.01), and health awareness(p<0.01), first menstruation before they reached 13 (p<0.01), heavy bleeding(p<0.01), family history(p<0.01). Factors affecting the dysmennorrhea of the respondents included the extent of bleeding, family history, health awareness, age during the first menstruation, and degree of stress, accounting for 13.1% of the total variance. Conclusion: To manage dysmenorrhea among girls, the results of the research indicate that students need to have proper awareness of health and manage stress through health education. Likewise, they need to be given positive follow-up management through a holistic nursing approach.

  • We present here $UBVI$ and H${\alpha}$ photometric results of stellar sources in the bubble nebula NGC 7635. The early type members are selected from the photometric membership criteria. H${\alpha}$ photometry allows us to detect 11 pre-main sequence candidates with H${\alpha}$emission. In addition, we performed PSF photometry for the Spitzer IRAC and MIPS 24${\mu}m$ images from archive (program ID 20726, PI: J. Hester) in order to search for the young stellar objects (YSOs). Total 19 sources are classified as YSOs (7 class I, 11 class II, and 1 transitional disk candidates) in the color-color diagrams according to the classification scheme of Gutermuth et al.. Among them, 7 YSOs have counterparts in optical photometric data. These stars can be divided into two groups at given color indices. It implies that there occurred the star formation events more than twice. We would like to discuss the star formation history in the bubble nebula using the results from SED fitter (Robitaille et al.), color composite image from IRAC bands, and spatial distribution of early type stars and YSOs.

  • A 12-year-old spayed female Yorkshire terrier dog was presented with two-weeks history of lethargy, mental dullness and polydipsia. Neurologic examination revealed proprioceptive defect of all limbs and loss of swallowing gag reflex. The dog revealed persistent dehydration, hypernatremia, hyperosmolarity and hyposthenuria. On magnetic resornance imaging (MRI), the mass were heterogeneous signality on T1 weighted images, hyperintense signality on T2 weighted image with contrast enhancement on hypothalamohypophyseal lesion. Based on these findings, the dog was suspected as having pituitary gland tumor. Through water deprivation test and response to desmopressin acetate (1-deamino-8-D-arginine, DDAVP), this case was diagnosed by central diabetes insipidus (CDI). This paper reports the clinical sign, MRI, response to the exogenous antidiuretic hormone of CDI due to suspected pituitary tumor in a dog and DDAVP administration was evaluated effective therapy to correct hypernatremia induced by CDI.

  • In this study, a methodology is investigated for the development of social responsibility program employed by major domestic companies under social pressure. It is true, however, that its infancy in history and lack of experience makes it difficult to run novel programs for the companies on their own and it naturally leads to copying and/or slight modification of what others do. Utilizing widely accepted SWOT analysis, stakeholders analysis and PDCA Cycle, a methodology for the successful programs with sustainability is proposed by reflecting business nature and strategic direction. Three real cases are analyzed. In addition, relationship and position with social welfare organizations is elucidated.

  • This study investigated several cases of interactive learning mediated by exhibits in a natural history hall during visits by middle school students. Five visiting cases were selected, in which visitors engaged actively in the interactions between them. Each visiting case was analyzed in terms of visiting discourse register and the modes of interaction in order to understand both visitors' meaning-making processes through the discourse flow and the characteristics of visiting discourse according to the features of exhibits. Results were as follows. The information provided in the exhibits was used as THEMEs in visitors' discourse and the visitors presented their information on the THEMEs as RHEMEs. The visitors made their own meaning for the exhibits by exchanging their information with each other. Interrogative sentences on the exhibit panels allowed visitors to make arguments. Similar exhibits displayed together helped visitors to compare those exhibits. These two features of the exhibits facilitated visitors' meaning-making processes in the natural history hall. The modes of interaction between visitors mediated by the exhibits showed that the information itself from the exhibits as well as visitors' opinion on the exhibits were frequently used as the elements for in-depth cognitive social interactions that allowed the visitors to construct meaning. Based on these results, we discussed that understanding in detail how visitors choose information from exhibits and construct visiting discourse is very important to improve visitors' collaborative science learning at a natural history hall.

  • There are many countries having a long history of exotic tree introduction from different countries and several countries including New Zealand, Brazil and Hungary have successfully introduced exotic trees. Korea's tree breeding program for introduction of exotic tree was originally started from 1924. Records reveal that hundreds of tree species were introduced from many countries and tested their germination and viability. About 415 introductions were eliminated since they had been introduced and tested. Subsequently, seven exotic trees that proved successful in trials and plantations have planted for afforestation. Simultaneously, several promising exotic trees are still under the test. In this paper, we will succinctly review and evaluate their comparative growth performance of the exotic trees in the plantation programs of the country to coping with climate change.

  • The pressing need to mitigate greenhouse gas emissions has stimulated a renewed interest in nuclear energy worldwide. However, while numerous countries have shown interest in nuclear power over the course of history, many of them have not continued their pursuit and chosen to defer or abandon their peaceful nuclear power projects. Scrapping a national nuclear power program after making initial efforts implies significant challenges in such a course or a waste of national resources. Therefore, this study aims to identify the crucial factors that influence a country's decision to terminate or hold off its peaceful nuclear power programs. Our empirical analyses demonstrate that major nuclear accidents and leadership changes are significant factors that lead countries to terminate or defer their nuclear power programs. Additionally, we highlight that domestic politics (democracy), lack of military alliance with major nuclear suppliers, low electricity demand, and national energy security environments (energy import, crude oil price) can hamper a country's possibility of regaining interest in a nuclear power program after it has been scrapped, suspended, or deferred. The findings of this study have significant implications for policymakers and stakeholders in the energy sector as they strive to balance the competing demands of energy security, and environmental sustainability.

  • This descriptive survey design study was aimed to investigate nursing students' perspectives of nursing care. One hundred seventeen junior or senior students in BSN program and 131 junior or senior students in RN-BSN program at K University were compared and contrasted in terms of their perspectives on nursing care. Using the instrument developed by Cho Kyoul-Ja and Song Mi-Ryung(1997), the data were collected from April 1st to April 30th in 2003. The findings of the research are as follows. 1. The average perspective score of the RN-BSN students was higher than that of the BSN students. 2. The RN-BSN students reported higher scores than those of the BSN students in perspectives on personal qualification and meanings, and perspectives on scope and function of their nursing care. However, there was no significant difference between the groups in overall nature and domains of nursing care. 3. In terms of the participants' demographic backgrounds such as, grades in the program, religion, history of hospitalization, there was no significant difference between the BSN and RN-BSN groups. 4. No significant difference was found within the RN-BSN group in terms of their nursing perspectives associated with the years of clinical experience. In conclusion, the score of nursing perspectives in RN-BSN student group was higher than that of the BSN students. No other differences were found in this study. The higher nursing perspective score in RN-BSN group is attributed to their clinical experience. Thus, it is suggested that philosophy and value of nursing should be taught early in nursing program in order for nursing students to obtain proper points of views on nursing care. In addition, nursing philosophy, holistic view, and humanistic values should be stressed in continuing education for clinical nurses in order for them to maintain dignitary perspectives in nursing care.
