An aquatic food chain was constructed to provide information of bioaccumulation of DEHP as followed: phytoplankton(Scenedesmus subspicatus) ${\rightarrow}$ zooplankton(Daphnia magna) ${\rightarrow}$ fish(Oryzias latipes). After 10 days of exposure to DEHP, the fish and culture water were analyzed for residual concentration of DEHP and BAF(Bioaccumulation Factor) was determined. In addition, BCF(Bioconcentration Factor) was calculated in exposure tank in which fish were only exposed DEHP by culture water. These experiments provide the relative importance between BAF and BCF. In this study, BCF and BAF did not show any significant difference. Another work in this study was model construction and application to investigate the effect of food chain structure to BAF in higher organism (fish). The model constructed in this study considered the biological characteristics of DEHP such as metabolic parameters, as well as the chemical characteristics such as solubility. This model could be used in prediction of bioaccumulation level in dependent of various food chain structures, when the target organisms or chemicals would be changed.

A pillow was fabricated through CAE(Computer Aided Engineering) and 3D printing, which can adjust automatically the height of the pillow when lying sideways and backwards according to the sleeping posture. The target height difference of the pillow was about 1.0 cm ~ 1.5 cm when the head weight difference was about 1.2 kg. Instead of using a complex mechanical device, it was based on an arch structure made of TPU. From the simulation, the optimum model was designed through series combination and the results were compared with the experimental ones. The final product had a height difference of about 2 cm according to the lying posture.

The purpose of this study was to analyze the problems of brands preferred by adolescents on sizing system and grading method and to provide a basic information for adolescent apparel manufacturers. Brands preffered by adolescents were obtained via a questionnaire from adolescents aged from 13 to 18 in Seoul and finally we selected upper 12 brands out of 20 brands they preffered. Also the graders of 12 brands were surveyed through direct interviews. The results indicated only 2 brands out of 12 brands(such as Adidas and Basic House) manufactured apparels for adolescents and most brands targeted customers in their early twenties as a main target market. As a results of researching the sizing system of 12 brands, women's apparel brands produced two sizes separately for upper and lower garments, unisex apparel brands produced garments in 4${\~}$8 sizes. For most of the brands, each size has a dimensional deviation on the same rate in all parts and 12 brands manufactured garments mainly with a dimensional deviation of 5cm in bust circumference and hip circumference.

The purpose of the study were to find out (1) the effect of motives on perceiver's image perception on ramie fabrics, and perceiver's trait, age and gender on sensory image evaluation of ramie fabrics. The research was a quasi experiment and experimental materials developed for the study were a set of material stimuli and semantic differential scales to measure sensory image of the stimuli, an aesthetic value scale. the independent design was motif design techniques(Plain Weave, burnt-out, embroidery, stripe, check). The subjects were 421 adults in Daejeon and Seachun. The results was as follows: The factor analysis of semantic differential scales for the ramie materials emerged 4 different image dimensions: attractiveness, hand, elegance, weight). The five design techniques showed significantly different image affects on some selective dimensions. The burn-out design gave the most attractive image, the embroidery design gave the softest image and plain weaved fabric presented the lightest hand image. Consumer's aesthetic values, gender and age tended to affect sensory image evaluation of ramie materials. On conclusion the result revealed that design strategy for the ramie material, design development though motives will be an essential process. and for material design pursued design image and target consumer's trait should be carefully considered.

This study investigates the breast cathexis and brassiere design preferences of Chinese citizens living in Hong Kong in order to provide marketing intelligence for bra manufacturers whose target customers are from this group of potential customers. A questionnaire composed of questions concerning breast shape evaluations, brassiere design preferences, and brassiere purchase and wear practices was administered to 165 Hong Kong Chinese female undergraduates(N=165). For an analysis of our data, we used the SPSS program(version 14.0). The results indicate that a majority of Hong Kong Chinese female undergraduates perceive their breasts as 'slightly smaller than normal' (n=59, 35.8%) or 'normal'(n=78, 47.3%) in volume, and 'conical'(n=77, 46.7%) or 'flat'(n=46, 27.9%). The results also suggest that Hong Kong Chinese women possess positive breast cathexis, with only a third of the respondents reporting dissatisfaction with their breasts. Women with dome-shaped breasts expressed the most positive breast cathexis, followed by those with cone-shaped breasts. The results also show that Hong Kong Chinese typically purchase 2 brassieres per year, which is a lower purchasing rate than their counterparts in Korea(Cha & Sohn, 2010) and Taiwan(ICT Life Style Research Center, 2004). The findings also demonstrate that the preferred brassiere color is black(57%), unlike in Korea, where women prefer skin-colored brassieres.

Civic participation in managing the work of a park is a natural experience, and urban culture has a role in forming and communicating ideas. However, when it comes to managing a copse, there is no clear scenic image. In this study, my intention was to determine a desirable scene involving a copse and suggest a target image for managing work from a scenic perspective. I selected 12 photographs and listed 10 pairs of adjectives that were judged to reflect the effect produced by the copse scene using the repertory grid development technique. In addition, I performed a scenic evaluation using the semantic differential(SD) method with each pair of adjectives. Factor analysis was performed based on questionnaire survey results, such that the scenic structure of the copse had a clear definition. In addition, the physical characteristics of the photographs were analyzed using Adobe Photoshop 6.0 and the correlations between the results of the questionnaire survey were understood using multiple regression analysis. A desirable scenic image of the copse became clear through this process and I was able to suggest various options of scenic images. Taking the aspects of urban culture into consideration, park improvement projects(including their planning stages) should be implemented by involving residents, which will lead to further development of park planning and maintenance theories and projects giving due consideration to residents' opinions.

This study was designed to investigate clinical features, allergy-inducing substances as well as foods, and nutritional behavior of allergic patients. Sixty-eight adult male and 78 adult female patients were surveyed by using the self-developed questionnairs. The results were as follows: 1. The common target organs of allergic symptoms included bronchus, skin and nose. 2. 37.7% of the subjects did not recognize their allergy inducing substances. Among the known substances, house-dust mite, food, temperature and weather change, pollens, smoke, air pollution materials, drugs and even stress provoked symptoms. 3. As for the food allergy, a number of foods were found to be implicated in allergic reactions. These foods included pork, chicken, seafoods such as mackerel, crab & shrimp, milk, egg, peanut, apple and pupa. Symptoms and signs of food reactions included urticaria, asthma, and rhinitis. 4. The nutrition adequacy ratio (NAR) of energy was below 0.75 for male patients and about 0.80 for female patients. And 24.0% of the subjects were regarded as excellent, 31.5% as fair, and 44.5% as poor in food related behavior evaluation.

The purpose of this study is to design and build fake news discrimination systems and methods using fact-checking guidelines. In other words, the main content of this study is the system for identifying fake news using Artificial Intelligence -based Fact-checking guidelines. Specifically planned guidelines are needed to determine fake news that is prevalent these days, and the purpose of these guidelines is fact-checking. Identifying fake news immediately after seeing a huge amount of news is inefficient in handling and ineffective in handling. For this reason, we would like to design a fake news identification system using the fact-checking guidelines to create guidelines based on pattern analysis against fake news and real news data. The model will monitor the fact-checking guideline model modeled to determine the Fact-checking target within the news article and news articles shared on social networking service sites. Through this, the model is reflected in the fact-checking guideline model by analyzing news monitoring devices that select suspicious news articles based on their user responses. The core of this research model is a fake news identification device that determines the authenticity of this suspected news article. So, we propose news article identification methods with fact-checking guideline on Artificial Intelligence & Bigdata. This study will help news subscribers determine news that is unclear in its authenticity.

Raphanus sativus var. hortensis f. raphanistroides Makino (Korean wild radish [WR]) are root vegetables belonging to the Brassicaceae family. These radish species mostly grow in sea areas in Asia, where they have been traditionally used as a medicinal food to treat various diseases. To investigate the effect of WR on neuronal cell death in SH-SY5Y cells, beta-amyloid was used to develop the cell death model. WR attenuated neuronal cell death in SH-SY5Y and regulated the mitogen-activated protein kinase (MAPK) signaling. WR extract also inhibited acetylcholinesterase inhibitor activity. Additionally, the WR treatment group ameliorated the behavior of the memory-impaired mice in a scopolamine-induced mouse model. In the behavior test, WR treated mice showed shorter escape latency and swimming distance and improved the platform-crossing number and the swimming time within the target quadrant. Furthermore, WR prevented histological loss of neurons in hippocampal CA1 regions induced by scopolamine. This study shows that WR can prevent memory impairment which may be a crucial way for the prevention and treatment of memory dysfunction and neuronal cell death.

This paper explores how to teach Chinese, using multi-media resources such as Chinese dramas and focusing on one of Jin Yong's dramas, The Return of the Condor Heroes. The purpose of this study is to develop teaching methodologies for university students learning Chinese through drama to integrate language skills: enhancing communicative competence and understanding Chinese cultures. First, the overview of previous studies provides several cases of foreign language education using drama. Teaching Chinese through drama can be an integrative education because students can develop their communicative competence as well as understand the cultures of the target language. In other words, the contexts of drama may offer rich sources of the history of China, Han Chinese ethnocentrism, and knowledge of Chinese literature as well as geography. Second, this study applies the principles of Tomlinson (2010) for materials development in language teaching into the case of Chinese drama. It concentrates on Jin Yong's The Return of the Condor Heroes that the author has used in the Chinese language courses for three years. It examines the characteristics of the drama for developing effective ways of teaching and learning Chinese language and culture. Furthermore, it discusses the impact of using drama on changes in students' pervasive perceptions about unnecessity of Chinese classical literature. Third, this paper presents some sample lessons which may help teachers to develop understanding of how to organize lessons through drama. Finally, it illustrates university students' opinions about using drama to learn Chinese.
