  • In vertebrate reproductive system, estrogen receptor (ER) plays a pivotal role in mediation of estrogenic signaling pathways. In the present study, we report the cDNA cloning, expression analysis, and transcriptional activity of ERβ1 subtype from medaka Oryzias dancena. The deduced O. dancena ERβ1 (odERβ1; 519 amino acids) contained six characteristic A/B to E/F domains with very short activation function 2 region (called AF2). A phylogenetic analysis indicated that odERβ1 was highly conserved among teleost ERβ1 subgroup. A conventional RT-PCR revealed that the odERβ1 transcripts were widely distributed in the multiple tissues, the ovary, brain, gill, intestine, kidney, and muscle. Further, the relatively higher odERβ1 expressions in the ovary and brain were clearly reproduced in RT-qPCR assay. When HA-fused odERβ1 expression vector was transfected into HEK293 cells, an immunoreactivity for odERβ1 was mainly detected in the nucleus part. Finally, an estrogen responsive element driven luciferase reporter assays demonstrated that the transcriptional activity of odERβ1 significantly increased by estradiol-17β (E2) in a dose dependent manner (p<0.05). However, fold-activation of odERβ1 in the presence of E2 was markedly weak, when it compared with those of O. latipes ERβ1. Taken together, these data suggest that odERβ1 represents a functional variant of teleost ERβ subtype and provides a basic tool allowing future studies examining the function of F domain of ERβ1 subtype and expanding our knowledge of ERβ evolution.

  • Ecological and ecosystem database is becoming very necessary to understand origins and relationship between human and nature and also to minimize disturbance caused by human activities. An ecological information portal can play important roles as a computing system to collect knowledge, distributed research findings and separated data from researchers. In this study, we designed and developed ecological information portal service (EcoBank 1.0) for collecting and providing ecological information for diverse classes of stakeholders. To reach the goal, we had reviewed related and comparable ecological database portals to design conceptual structure of EcoBank system including database management framework. Then, we developed some functions of ecosystem analysis for each stake-holders (researchers, general public and policy makers). As a result of this study, we successfully designed of EcoBank system covering the functions of Digital Object Identifier(DOI) publishing and data quality management process. Also, we (1) applied ecological indices for calculating biodiversity by administrative boundary for policy makers, (2) provided statistical information of econature map for general public and distribution characteristics of species for researchers. To make a successful establishment of EcoBank, we have to collect and build up related database and offer various and reliable ecological data consistently. We expect that the successful construction of EcoBank will help not only to accomplish sustainable development goals but also to raise the welfare of ecosystem in Korea.

  • This study was conducted to investigate the degree of practice of dietary behavior and dining out in accordance with intake of sodium among male and female adults aged 20 years or older residing in the Seoul Metropolitan area or Chungcheong Province. A total of 530 copies of the questionnaire were distributed from May to July, 2014. The SH group who responded that they eat a lot of sodium constituted 30.6% (158 people), followed by the SM group who responded that their sodium intake is about average at 55.7% (288 people) and the SL group who answered that they do not eat much sodium at 13.7% (71 people). Those in the SL group showed positive results for dietary behavior patterns. The SL group showed the lowest rate in terms of how often they eat harmful foods, including processed foods, sweet foods, salty foods, or food with high animal fat content such as pork belly. Positive results among the SL group were prominent in terms of avoiding over-drinking, regular exercise, and nutritional knowledge, indicating greater health management. The distribution of each group in terms of self-perceived sodium intake showed significant differences across age, gender, and household income in terms of frequency of fast food intake, regularity of meals, purchase of foods with consideration of sodium amount, frequency of missed meals, balance of food intake, and health management habits.

  • This study was performed through one-to-one interviews or group sessions with single un-married foreigners living and working in Korea. A total of 150 questionnaires were distributed, and 109 were analyzed. This demographic becomes immersed in local cuisine searching for new food dishes and experiences. These foreigners were an excellent test group who came from a non-Korean domestic cuisine background and who were subsequently exposed to Korean cuisine over an extended period during which changes occurred in their diets and food preferences. We found that the longer the foreigners stayed in Korea, the more they ate Korean food and adapted to traditional dishes such as Korean stews and hot-pots. In general, Chinese, Japanese, and South-east Asians regarded Korean food as nutritious, whereas people from a western or European background considered it health conscious food. In contrast, South-east Asians, in particular, found Korean food aroma unpleasant. This study describes how diets and views of Korean food evolved in foreigners with time by providing objective opinions and data on the acceptance of Korean food by foreigners and hints the direction in which Korean cuisine should be developed to further its globalization.

  • The term "big data" has recently gained widespread attention in the field of information technology (IT). One of the key challenges in making use of big data lies in finding ways to uncover relevant and valuable information. The high volume, velocity, and variety of big data hinder the use of solutions that are available for smaller datasets, which involve the manual interpretation of data. Semantic computing technologies have been proposed as a means of dealing with these issues, and with the advent of linked data in recent years, have become central to mainstream semantic computing. This paper attempts to uncover the state-of-the-art semantics-based approaches and tools that can be leveraged to enrich and enhance today's big data. It presents research on the latest literature, including 61 studies from 2011 to 2014. In addition, it highlights the key challenges that semantic approaches need to address in the near future. For instance, this paper presents cutting-edge approaches to ontology engineering, ontology evolution, searching and filtering relevant information, extracting and reasoning, distributed (web-scale) reasoning, and representing big data. It also makes recommendations that may encourage researchers to more deeply explore the applications of semantic technology, which could improve the processing of big data. The findings of this study contribute to the existing body of basic knowledge on semantics and computational issues related to big data, and may trigger further research on the field. Our analysis shows that there is a need to put more effort into proposing new approaches, and that tools must be created that support researchers and practitioners in realizing the true power of semantic computing and solving the crucial issues of big data.

  • This study investigated the effect of cooking class on improvement of eating behaviors and satisfaction with cooking activities in children. The questionnaires developed for this study were distributed to 380 mothers during June to August, 2011. A total of 286 questionnaires were used for analysis (81.7%), and frequency analysis, ANOVA, and ${\chi}^2$-test were completed using SPSS (version 14.0) software. The children with cooking experience (52.7%) showed more improvement of eating habits than children with no cooking experience (36.4%). Both types of children showed an 'unbalanced diet' with respect to eating habits. The overall satisfaction level was an average of $3.84{\pm}0.62$. The effects after cooking activities varied for different aspects of improvement of eating habits: 'Correcting unbalanced diet' was $4.26{\pm}0.66$, 'nutrition knowledge' was $4.06{\pm}0.70$, 'dining etiquette' was $4.09{\pm}0.63$, and 'regular meals' was $4.15{\pm}0.73$. There was a significant difference between genders with regards to correcting unbalanced diet with vegetables (p<0.01). Ages from 10 to 12 were able to improve unbalanced diet with 'grains' (p<0.001), while 'Kimchi' (p<0.05) and 'paste' for ages from 10 to 12. In conclusion, cooking activities are regarded as effective in correcting unbalanced diet and eliciting positive changes in eating behavior.

  • Asbestos have been used around the world because of reliable and cost-effective physicochemical characteristics. After incubation period about 15-40 years asbestos can cause various cancers, including malignant mesothelioma when inhaled into the air. These properties turned out, asbestos have been banned from using in developed countries. Also in Korea also, the use of asbestos was banned across the board by revision of Industry Safety and Health Act in February 2009. Therefore, the problem of asbestos is not when using. It is about dismantling, maintenance, and the final processing of asbestos waste. Asbestos Cement slates which is Widely distributed throughout the country as roofing materials has much scattering potential compare with inside materials. Also Ministry of Environment is planning to introduce legislation 'Asbestos Safety Management Act' through Environment Announcement and The same Act. 24 show as follows. Minister of Environment or governor should do survey on the actual condition targeting rural buildings with slates and partly or fully fund to dissolve, remove asbestos slate which was used in each buildings. Therefore, to solve these problems, database-building and necessity of management strategies have been continually arisen. So this study was performed. Its application value is very high in terms of its political, economic. Asbestos Cement Slates database could build to collect national registered building data and then using GIS, asbestos cement Slates distribution map were constructed in each province's cities and counties of the country. And this map by Application, construction was to visualize by application, construction of year. Through these results, information of Asbestos Cement Slates could visually inform to policy makers, asbestos dismantling and management contractor, and civilian and it would alleviate the gap of knowledge information. This is expected to be utilized by medium and long-term and effective plan for demolition and dismantling of asbestos cement Slates.
