Rice (Oryza sativa L.) is one of the most important staple foods in Korea and the consumption of brown rice is increasing annually. The objective of this study is to investigate the physicochemical, hydration and textural properties related to eating quality of cooked brown rice by using glutinous, semi-glutinous, four non-glutinous and four colored varieties. The moisture, protein and total dietary fiber contents of brown rice are shown in the range of 11.1~12.6%, 6.6~8.7% and 6.28~12.40%, respectively. The amount of water uptakes for brown rice during the hydration has shown significant differences. The glutinous variety of Boseogchal indicate the highest water absorption levels by reaching $0.38gH_2O/g$. The hardness of hydration for Seolgaeng is distinctively lower than those of the other brown rice varieties. According to the textural characteristics of cooked brown rice when using the Tensipresser, the hardness of Boseogchal, Baegjinju and Seolgaeng all exhibit the lowest values out of ten varieties and the highest levels of adhesiveness.

유자의 이용성을 높이기 위해 유자펙틴 추출물을 첨가한 요구르트를 제조하여 이화학적 특성을 평가하였다. 본 연구에서 추출된 유자펙틴 추출물의 uronic acid 함량은 53.93%였다. 유자펙틴 추출물 첨가 요구르트의 이화학적 특성 실험에 따르면 실험군의 pH는 4.3으로 나타났으며 실험군의 유산균 수는 식품공전에 명시된 요구르트 제조 기준에 적합하였다. 정상유동 특성의 경우 유자펙틴 추출물 첨가 요구르트의 n값은 1보다 낮은 범위(n=0.33~0.44)에 있어 shearthinning 유체 특성이 있었다. 점조도 지수, 겉보기 점도의 경우 대조군보다 모든 유자펙틴 추출물 첨가 요구르트가 유의적으로 높았다. 동적 점탄성의 경우 저장탄성률(G")과 손실탄성률(G"")은 주파수가 증가함에 따라 유의적으로 증가하였고, G"의 수치가 G""보다 뚜렷하게 높았다. 유자펙틴 추출물 첨가 요구르트의 복소점도 값은 대조군보다 유의적으로 높았으며, 점성적 성질에 비해 탄성적 성질이 더욱 우세하였다. 또한 유자펙틴 추출물 첨가 요구르트는 약한 겔과 같은 구조적 성질을 가지고 있었다. 결과적으로 유자펙틴 추출물 첨가가 요구르트의 점탄성에 영향을 줄 수 있음을 확인하였다. 소비자검사에서도 실험군의 기호도가 더 높은 것으로 보아 우수한 품질임을 알 수 있었다. 따라서 유자를 이용한 후 버려지는 유자껍질에서 펙틴을 추출하여 요구르트 제조에 첨가함으로써 향후 친환경적이며 고부가가치 요구르트 제조가 가능할 것으로 생각한다. This study investigated the effects of Yuza pectin extract (0, 0.1, 0.15, and 0.2%, w/v) on the physicochemical, microbial, rheological, and sensory properties of yogurt. Pectin extract was extracted from Yuza peel by using citrate after juicing the flesh. The total sugar content of Yuza pectin was 89.07%. The pH of Yuza pectin extract-added yogurt was 4.43. All Yuza pectin extract-added yogurt samples showed shear-thinning flow behaviors (n=0.33∼0.44). The values for apparent viscosity (0.34∼0.47 Pa・s), consistency index (4.48∼10.25 Pa・s<SUP>n</SUP>), yield stress (6.56∼17.61 Pa), storage modulus (47.96∼75.21 Pa), and loss modulus (19.79∼26.06 Pa) for 0.1∼0.2% (w/v) Yuza pectin extract-added yogurt were considerably higher than those of the control. These result indicated that Yuza pectin extract could enhance steady and dynamic shear rheological properties of yogurt. The sensory scores of Yuza pectin extract-added yogurt were higher than those of the control.

This study investigated elementary school teachers` difficulties in the compass making activity. Based on the results of the teacher survey, we improved the compass making activities and applied to elementary science lessons. One hundred three elementary school teachers who had experience in teaching the compass making activity participated in this survey. The improved compass making activities were applied to two classes and pre- and post tests were conducted to check the effectiveness of the improved activities in conceptual understanding. The result of the survey showed that the inaccurate experimental result made teachers difficult in their teaching. In addition, teachers hoped that activity would be improved as a simple activity without magnetizing process. Considering the result of the teacher survey, we developed the improved compass making activities with the permanent magnetics. We can confirm that the improved compass making activities show that the more accurate experimental result than the textbook activity.

The masked play can be said to be the dance containing both the theatrical element and the dance element of folk dance. In general, it can be divided into Haeseo masked dance of the northern district Sandae play of the central district and Deulnoleum and Ohkwangdae of the southern district. This study attempted to compare and analyze masked play according to its regional districts and kinds. And it sought to investigate the expressive technique embedded in masked plan alone by classifying the theatrical and dance element into the content element, dramatic element and dance element. Second, this study not only laid the foundation for this expressive technique to be applied to Korean creative dance by illuminating it from many angles but also attempted to make a creative approach through the combination of the traditional folk drama and dance of play and festival. An attempt was made to investigate the scheme to attempt a new creative approach through the grafting of Korean creative dance and general dance based on the expressive technique of masked play by dividing it into the ceremonial aspect, the expressive aspect and the dramatic aspect. First, it is possible to investigate the ceremonial aspect of masked play by dividing it into the ceremony of exorcism, the ceremony of birth and the ceremony of shamanism. The ceremony of exorcism is the ceremonial one that is performed largely in the beginning of drama. The ceremony of shamanism is the one performed at the end of drama. The meaning of its sequence is important, and the ceremony of birth after death has a large meaning related to the thought of the transmigration of souls. The ceremonial aspect of this masked play are not simply related to the past ceremony but also has an influence on the thought and emotion of contemporary creative dance. Korean creative dance expresses the world of shamanic death originating from offering the sacrifice ritual to the heaven and has the thought and emotion that only our dance has in creative performance. Contemporary Korean creative dance not simply refers to contemporary dance but also contains several ceremonial aspects inherent in traditional Korean dance. One of the distinguishing features of foreign dance and Korean dance is that this ceremonial dance is expressed in subject and content. Contemporary dance accommodates the aspect of traditional thought as well as something new. It is thought that this can be drawn from the ceremonial aspect found in masked dance, one of traditional Korean dances. Second, an investigation into the expressive aspect of masked play revealed that it could be divided into the emotional aspect, the formal aspect of play-performing method and the aspect of Yin and Yang and Five Elements. Masked dance, overall, expresses human feelings such as joy and anger together with sorrow and pleasure in the method of its play development. Especially, it expresses human feelings expressed in Korean dance such as exhilaration, pleasure, sorrow and remorse, and this emotional aspect finds remarkable expression through the musical element of masked dance and the expression of the mask. The subject of masked play was to share and criticize the realistic problem of the day. Dance movements were created by collective exhilaration to fit the times. Contemporary Korean creative dance should be able to choose the subject that the general public can share and enjoy and should be movements appropriate to this age. It is necessary to approach it with the Korean sentiments of joy and anger together with sorrow and pleasure in the work of dance. Accordingly, we could approach new creative dance if we are to identify the emphasis of movement contained in masked play, develop a new dance language and extend expressive techniques. Finally, the element of Yin and Yang and Five Elements finds expression space, dance movement and costume. Dance movements can be seen as consistent with the oriental concept rooted as arts in life by integra

Objectives: This study aims to investigate the atmospheric concentration of polycyclic aromatic hydrocarbons (PAHs) and volatile organic compounds (VOCs) and the urinary concentration of biomarkers in residents near the Shinpyeong·Jangrim Industrial Complex to compare them with those of residents in a control area. Methods: Hazardous air pollutants (PAHs and VOCs) were measured in an exposure area (two sites) and a control area (one site). Urine samples were collected from residents near the industrial complex (184 persons) and residents in the control area (181 persons). Multiple linear regression analysis was used to identify which factors affected the concentration of PAHs and VOCs metabolites. Results: The average atmospheric concentration of PAHs in Shinpyeong-dong and Jangrim-dong was 0.45 and 0.59 ppb for pyrene, 0.15 and 0.16 ppb for benzo[a]pyrene, and 0.29 and 0.35 ppb for dibenz[a,h]anthracene. The average atmospheric concentration of VOCs was 1.10 and 0.99 ppb for benzene, 8.22 and 11.30 ppb for toluene, and 1.91 and 3.05 ppb for ethylbenzene, respectively. The concentrations of PAHs and VOCs in residents near the Shinpyeong·Jangrim Industrial Complex were higher than those of residents in the control area. Geometric means of urinary 2-hydroxyfluorene, 1-hydroxypyrene, methylhippuric acid, and mandelic acid concentrations were 0.45, 0.22, 391.51, and 201.36 μg/g creatinine, respectively. Those levels were all significantly higher than those in the control area (p<0.05). In addition, as a result of multiple regression analysis, even after adjusting for potential confounding factors such as gender and smoking, the concentration of metabolites in urine was high in residents near the Shinpyeong·Jangrim Industrial Complex. Conclusion: The results of this study show the possibility of human exposure to VOCs in residents near the Shinpyeong·Jangrim Industrial Complex. Therefore, continuous monitoring of the local community is required for the management of environmental pollutant emissions.

This study was conducted to analyze the starch and pasting properties of fourteen glutinous rice varieties with different maturity, and we compared the textural characteristic difference in relation to stickiness of glutinous rice cake. The whiteness alues of grain appearance showed significantly differences in the order of early ˂ medium < mid-late maturing glutinous rice varieties. Early maturing glutinous rice varieties exhibited a little high tendency for crude protein content than that of other varieties. Mid-late glutinous rice varieties showed higher of short chain ratio of 6 to 12 in DP of amylopectin whereas, medium length chains of 13 to 24 were significantly low. According to Rapid Visco-Analyzer measurement glutinous rice flours and starches, peak time showed high negative correlation with short chains of 6 to 12 in DP. The hardness of mid-late maturing glutinous rice cake was distinctly lower than that of the other glutinous rice varieties. Furthermore, mid-late maturing glutinous rice varieties, Baegseolchal, Dongjinchal and Baekogchal tend to show lower and slower in hardness changes of rice cake during storage. The hardness changes of glutinous rice cake had positive correlation with the amylose content and peak time and negative correlation with short chains of 6 to 12 in DP of amylopectin, respectively.
