This study was conducted to investigate how child-care teachers participate, practice mealtime instruction, and perceive difficulties in food service, focusing on comparison between the teachers caring two different age groups: children younger than three years (Younger Group) and those three years or older (Older Group). Questionnaires were distributed to 151 child-care centers in Kwanak-gu, Seoul, Korea during December, 2011. Only the data from 25 child-care centers, where two respective teachers in charge of Younger Group and Older Group completed the questionnaires, were analyzed. The results showed that there was no difference in terms of child-care teachers' participation in food service practice between the two groups, except for serving method; 'Pre-plated' serving was used significantly more often in Younger Group, whereas 'Line-up' serving was used in Older Group. Approximately, three quarters of the child-care centers had policies or guidelines on mealtime instruction. During mealtime, child-care teachers tended to use frequently verbal instructions such as "sit up straight when you eat" about eating manner, "don't be picky with your food" about eating habit, and "wash your hands before eating" about eating procedure in both the groups. There was no statistically significant difference regarding child-care teachers' perceived difficulties in food service between the two groups. These results indicated that child-care teachers' participation and mealtime instruction in food service did not differ between the two age groups, although children's development of digestion and eating skill differed by age. Therefore, training should be provided to child-care teachers about food service practices and mealtime instruction appropriate to children's age.

The purpose of this study is to identify the design features appropriate for the altered physical characteristics of pregnant women and formulate the direction of future design and development of maternity wear. A Delphi research method based on a panel of experts and pregnant women was used and the survey was conducted to determine the suitability of maternity wear. The survey found that A-line silhouette outerwear with round necklines, with wide sleeves and snap-button fastening on the front with a formal and decent look was considered appropriate as maternity and postpartum wear. Shirts and blouses long enough to cover the hip area to complement women's curvy and full figures, especially around the bust, waist, and hip areas during the later stages of pregnancy were found to be appropriate. Calf-length pleated skirts were comfortable to wear during pregnancy due to the abundant freedom of movement and space offered by pleats. Ankle-length straight leg pants were rated appropriate in terms of comfort and style both during late stages of pregnancy and at work postpartum. Dresses decorated with pleats from the armholes all the way down to the knees were found to provide high levels of comfort at the abdomen, chest, and hips, and considered appropriate. Based on this study results, a follow-up study will be conducted to examine the design of maternity wear during pregnancy as well as at work after pregnancy.

Fast Imaging Solar Spectrograph (FISS) is an instrument developed by Seoul National University and Korea Astronomy and Space Science Institute and installed at the 1.6 meter New Solar Telescope of Big Bear Solar Observatory. Using this instrument, we observed solar filaments and analyzed the data focusing on determining the temperature and non-thermal velocity. We inferred the Doppler absorption widths of $H{\alpha}$ and Ca II 8542$\bar{A}$ lines from the line profiles using the cloud model. From these values, we separately determined temperature and non-thermal velocity. Our first result came from a solar filament observed on 2010 July 29th. Temperature inside a small selected region of this ranges from 4500K to 12000K and non-thermal velocity, from 3.5km/s to 7km/s. We also found temperature varied a lot with time. For example temperature at a fixed point varied from 8000K to 18000K for 40 minutes, displaying an oscillating pattern with a period of about 8 minutes and amplitude of about 2000K. We will also present new results from filaments observed in 2011 summer.

The objective of this study is to propose a method by which movement fitness can be evaluated using a three-dimensional virtual garment simulation program. To this end, five types of jean pants for men were evaluated on the program by setting the avatars to make particular movements to examine the level of pressure on each body part. To verify whether the clothing pressure measurement produces valid and reliable results, virtual garment simulation program was utilized. The results indicated that there were significant differences in the levels of pressure on body parts depending on the type of test garment and motion. In addition, the clothing pressure measurement results were in line with the appearance evaluation results suggested by a previous study. Based on this set of results, the nomological validity of the clothing pressure measurement program used in this study was verified. Moreover, we employed an appearance evaluation along with the clothing pressure measurement to verify the reliability of the program; there was a high correlation between clothing pressure measurements and appearance evaluation measurements, indicating that measuring clothing pressures may well compensate for the limitations of appearance evaluation. We expect the results of this study to make valuable contributions in facilitating the digitalization of the fashion industry. Furthermore, this study also is significant in that it has suggested 3D virtual fitting programs as a solution to the long-criticized problem related to the evaluation of movement fitness in existing virtual garment simulation programs.

Founded on a close relationship between exhibition scenarios and media, this study was conducted 1) to establish exhibition arrangement types by using three analytical indicators, such as arrangement types of exhibition, groupings of similar exhibition media, and exhibition density; and 2) to demonstrate the importance of considering the characteristics of exhibition arrangement types by using viewing behavior codes as a major analytical indicator. The following three types were investigated in this research: First, the Independent type (Type C) was found to be strongly influenced by architectural and spatial forms, especially by low exhibition density and high visual information. Also, compared with the Wall Dominant type, low number of viewing behavior codes and distribution was found even though there were high correlations among viewing behavior codes. This is assumed to be due to low exhibition density. Second, the Wall Dominant type (Type A) was found to be not influenced by architectural and spatial forms. This is because space is planned and restructured centering on the wall type showcases. At the planning stage of exhibition, it is easy to divide or combine space according to the contents and structure of exhibition scenarios. Compared with the Independent type, low correlations were found among viewing behavior codes. This is due to low participation or manipulation exhibitions. However, this implies that more active viewing behaviors can be induced if appropriate exhibition techniques and arrangement methods are used for each exhibition content. Third, the Independent Dominant type (Type B) was found to confuse visitors in selecting routes by displaying too many exhibits at a limited space in a disorderly fashion. It failed to attract visitors to the main exhibition area, where a big space is formed in the center. Visitors were found to view exhibits that are arranged near the major traffic line.

Gamma irradiation ($\gamma$-IR) is reported to have diverse effects on immune cell apoptosis, survival and differentiation. In the present study, the immunomodulatory effect of a low dose $\gamma$-IR (5~10 Gy) was investigated, focusing on the role of NF-${\kappa}B$ in the induction of the B cell differentiation molecule, CD23/FceRII. In the human B cell line Ramos, $\gamma$-IR not only induced CD23 expression, but also augmented the IL-4-induced surface CD23 levels. While $\gamma$-IR did not cause STAT6 activation in these cells, it did induce both DNA binding and the transcriptional activity of NF-${\kappa}B$ in the $I{\kappa}B$ degradation-dependent manner. It was subsequently found that different NF-${\kappa}B$ regulating signals modulated the $\gamma$-IR-or IL-4-induced CD23 expression. Inhibitors of NF-${\kappa}B$ activation, such as PDTC and MG132, suppressed the $\gamma$-IR-mediated CD23 expression. In contrast, Ras, which potentiates $\gamma$-IR-induced NF-${\kappa}B$ activity in these cells, further augmented the $\gamma$-IR- or IL-4-induced CD23 levels, The induction of NF-${\kappa}B$ activation and the subsequent up-regulation of CD23 expression by $\gamma$-IR were also observed in monocytic cells. These results suggest that $\gamma$-IR, at specific dosages, can modulate immune cell differentiation through the activation of NF-${\kappa}B$, and this potentially affects the immune inflammatory response that is mediated by cytokines.
