The purpose of this study is to analyze elementary teachers' science class objectively and quantitatively using Mobile Eye Tracker. The mobile eye tracker is easy to wear in eyeglasses form. And experiments are collected in video form, so it is very useful for realizing objective data of teacher's class situation in real time. Participants in the study were 2 elementary teachers, and they are teaching sixth grade science in Seoul. Participants took a 40-minute class wearing a mobile eye tracker. Eye movements of participants were collected at 60 Hz, and the collected eye movement data were analyzed using SMI BeGaze 3.7. In this study, the area related to the class was set as the area of interest, we analyzed the visual occupancy of teachers. In addition, we analyzed the linguistic interaction between teacher and students. The results of the study are as follows. First, we analyze the visual occupancy of meaningful areas in teaching-learning activities by class stage. Second, the analysis of eye movements when teachers interacted with students showed that teacher A had a high percentage of students' faces, while teacher B had a high visual occupation in areas not related to classes. Third, the linguistic interaction of the participants were analyzed. Analysis areas include questions, attention-focused language, elementary science teaching terminology, daily interaction, humor, and unnecessary words. This study shows that it is possible to analyze elementary science class objectively and quantitatively through analysis of visual occupancy using mobile eye tracking. In addition, it is expected that teachers' visual attention in teaching activities can be used as an index to analyze the form of language interaction.

Objectives: Methyl bromide is a highly toxic substance that can cause systemic poisoning, neurotoxicity, pulmonary edema. Methyl bromide is a widespread fumigation agent used for import and export quarantine, but there is little data on exposure assessment of workers participating in such fumigation. Therefore, this study aims to investigate the exposure level of methyl bromide among workers and the concentration distribution of methyl bromide in the workplace during fumigation. Methods: For this study, one wood tent and one container fumigation area in Pusan, and one wood tent fumigation area in Incheon were investigated over three months from June 2001. Results: Methyl bromide exposure levels for container fumigation workers were from undetected to 1.86 ppm and from undetected to 2.28 ppm for tent fumigation workers as an 8 hr TWA. After opening the container door, the methyl bromide concentration in the container decreased rapidly over time, but the concentration remained over 1 ppm even after about one hour. The concentrations around the tent during its removal were highly affected by wind, but were detected in a range from undetected to 11.97 ppm. Conclusions: This study confirmed that both container and tent fumigation caused workers to exceed the exposure limit of 1 ppm as an 8 hour TWA. In particular, it could be confirmed that a situation exists in which the worker may be exposed to high concentrations of methyl bromide when opening the container or removing the tent due to the nature of the work. Therefore, it is very important to improve working methods and to wear appropriate personal protective equipment.

The purpose of this article is to argue that Korean music, Yukjabaegi (six-bit songs), helps us overcome grief. It is not untrue to say that Yukjabaegi is among the greatest types of music in Korea. This is a testament to the prominence of this statue among Han Ak (Korean music, 韓樂). Empathy is an inherent human quality involving all parts of the brain which is also linked to feelings of love. Empathy is created the moment we imagine ourselves in someone else's situation. Moreover, if empathy is good for us, the generation of empathy may actually mobilize our strength. Koreans have superior strength in overcoming grief and difficult situations by singing together. Often Koreans feel that their lives and labors are difficult, they start singing Yukjabaegi because they consider grief and anxiety wear on a person more than hard work. Listening to and singing Yukjabaegi can cheer up people who feel as limp as a rag after hard labor. Tackling reality and venting the experience via creative expression is bound to be healthy. Under a change of the rhythm pattern, Yukjabaegi thus becomes a major form of amusement for those suffering from difficult situations and comes as a true friend to share in our grief with us. Singing together via Yukjabaegi is a time to share grief. Thus, this, author believes that it is related to empathy. It helps us overcome grief by means of music therapy.

PURPOSE. To investigate the fatigue and fracture resistance of computer-aided design and computer-aided manufacturing (CAD/CAM) ceramic molar crowns on dental implants and human teeth. MATERIALS AND METHODS. Molar crowns (n=48; n=8/group) were fabricated of a lithium-disilicate-strengthened lithium aluminosilicate glass ceramic (N). Surfaces were polished (P) or glazed (G). Crowns were tested on human teeth (T) and implant-abutment analogues (I) simulating a chairside (C, crown bonded to abutment) or labside (L, screw channel) procedure for implant groups. Polished/glazed lithium disilicate (E) crowns (n=16) served as reference. Combined thermal cycling and mechanical loading (TC: $3000{\times}5^{\circ}C/3000{\times}55^{\circ}C$; ML: $1.2{\time}10^6$ cycles, 50 N) with antagonistic human molars (groups T) and steatite spheres (groups I) was performed under a chewing simulator. TCML crowns were then analyzed for failures (optical microscopy, SEM) and fracture force was determined. Data were statistically analyzed (Kolmogorow-Smirnov, one-way-ANOVA, post-hoc Bonferroni, ${\alpha}=.05$). RESULTS. All crowns survived TCML and showed small traces of wear. In human teeth groups, fracture forces of N crowns varied between $1214{\pm}293N$ (NPT) and $1324{\pm}498N$ (NGT), differing significantly ($P{\leq}.003$) from the polished reference EPT ($2044{\pm}302N$). Fracture forces in implant groups varied between $934{\pm}154N$ (NGI_L) and $1782{\pm}153N$ (NPI_C), providing higher values for the respective chairside crowns. Differences between polishing and glazing were not significant ($P{\geq}.066$) between crowns of identical materials and abutment support. CONCLUSION. Fracture resistance was influenced by the ceramic material, and partly by the tooth or implant situation and the clinical procedure (chairside/labside). Type of surface finish (polishing/glazing) had no significant influence. Clinical survival of the new glass ceramic may be comparable to lithium disilicate.

Since fashion is considered to be a cultural product and belongs to the formative art as well, the changes in fashion reflect those of society. Modern fashion has emerged from the period when people would follow the popular fashion uniformly, and moved toward the age of diversity, expressing not only the inner desires and aesthetic sensibility of individuals but also the freedom from formality and traditional restrictions. This kind of changes in expression became important motives for modern dress design following the present cultural phenomena, and, so called "outerwearization" of the undergarment or "infra apparel" exemplifies this situation. Corset especially has been playing a vital role in exaggerating and emphasizing the beauty of female body and correction of its shape. Today, one can frequently witness corset in street fashion along with brassier, Its sister concept. This "outerwearization" of the undergarment is supplanted as a syndrome, and it is defined as "supra syndrome" using "supra" as the opposite meaning to "infra". This unique phenomenon of modern fashion cannot be explained by a single social aspect, but as a mixed state of eroticism, fetishism, feminism, demonstrationists and expressionism among several current phenomena. The advent of "supra syndrome" and its cultural background were illustrated and stand-out "supra syndrome" exhibited by many world-renowned designers were analyzed in this study. As the result of study, six design pieces were developed and produced in three groups, based on different corset motifs. This study reaffirms that creativity of design is limitless and the imaginative abilities alone cannot accomplish higher level of design and development of works of fashion unless they are accompanied by the understanding of historical background, periodical circumstances and cultural phenomena. In this study, utilizing the modern apparatus such as computer and the advent of the modern technology was also found helpful in creative fashion design process.
