  • This study compares the influence of perceived public opinion on Internet users' willingness to expression in real space with in cyber space. In real space, people who perceive their opinions as minority opinion are reluctant to express theirs publicly because of fear of isolation. But cyber space is the anonymous world. So we can expect that people express their opinions freely without the fear of isolation in this space. This study's results provide the support for our expectation. In cyber space, the minority perception group has as the high willingness to expression of their opinion about the abrogation of the Korean Family Rights Raw as the majority perception group. Both of in cyber space and in real space, it is the perception failure group that makes discrepancy in the willingness to expression. This group has the lowest willingness to expression in both space. However, the other predictors of willingness to expression in cyber space are similar to those in real space. Issue salience, Communication apprehension, and Age are the very significant predictors of willingness to expression in both spaces. Sex and ideology are significant predictors in real space, while the frequency of online conversation is the significant predictor in cyber space.

  • Based on the safety of irradiated foods which was demonstrated from the toxicological, microbiological and nutritional points of view, irradiation has been identified as a viable technology for food preservation and processing, having a potential both of reducing storage losses by controlling spoilage organisms, sprouting and ripening, and of improving hygienic quality of raw and processed products. Research and development over decades in the field of food irradiation have led to the regulatory approval in 37 countries and of them 25 countries including Korea are commercially utilizing food irradiation process. Although progress towards acceptance of food irradiation by the industry is slow, actual market trials have shown that once consumers have understood this technology, they are willing to buy irradiated foods. Considering recent advances in food irradiation and restrictions in the use of chemical fumigants, it is expected that food irradiation is in the process of "taking off". This paper deals with up-to-date progress in food irradiation with particular reference to domestic activities in legislation, consumer perception, commercialization, and potential applications in the food industry.

  • Recycled aggregate has structural limitations in that it cannot be actively used for use as a structural building material due to quality deviations such as increase in cracks, decrease in constructability during in-situ casting, and decrease in strength. Although the government gives incentives to use recycled aggregate concrete for major structural parts of buildings to revitalize recycled aggregate concrete, there is a perception that the quality control of recycled aggregate producers that produce raw materials is insufficient. In this study, recycled aggregate, I checked the quality of the company that handles the quality. We are working on this.

  • Building Information Model (BIM) is increasingly being used in the research of construction. The demand for low-cost and efficient access to architectural models is also on the rise. However, generating a parametric model from a point cloud will face interference from other facilities and will be affected by the quality of the measured point cloud. This paper describes a method for generating parametric models from laser-scanned point clouds. With slice voxel selection and line segment detection, the structural framework of the walls can be quickly extracted. By reducing the impact of missing furniture and data on the room, the new approach is applicable to most raw point clouds. This method has potential in multiple directions such as rapid BIM modeling, large-scale room reconstruction, and robot spatial perception.

  • The purpose of this study was to investigate the perception of aseptic foods (sterilized foods with radiation technology) in cancer patients in Busan. The subjects were 192 cancer patients at a hospital. This study was performed through interviews using questionnaires. Patients had perception scores on the need to develop aseptic foods (4.30 points out of 5.00), use aspetic foods (4.06/5.00), and intake aseptic foods (4.04/5.00). Patients less than 59 years old had significantly higher perception scores than those over 60 years old (p<0.05). The scores on aseptic food indicated the importance of various factors, including sanitation (4.86/5.00), good materials (4.82/5.00), nutritional value (4.79/5.00), unused of monosodium glutamate (MSG) (4.66/5.00), taste (4.61/5.00), and reasonable prices (4.60/5.00). The patients who were college graduates showed significantly higher scores and importance in good materials, proper packaging unit, simple cooking methods, food diversity, and familiar foods (p<0.05). In the aseptic menu items, patients wanted to include seasoned raw vegetables (4.11/5.00), a set menu (including cooked grain, soup, and a side dish) (4.08/5.00), seasoned cooked vegetables (4.04/5.00), low sodium kimchi (3.98/5.00), and fermented sauces (3.92/5.00). The patients with gastrointestinal cancer and other cancers (e.g. breast, thyroid, and renal cancer) had significantly higher necessity scores than lung patients for stew, seasoned raw vegetables, salad, low sodium kimchi, and a set menu (p<0.05).

  • The broiler marketing managers at department stores were most considered the brand whereas those at supermarket were most considered price when they purchased raw chicken. The whole chicken was distributed as fresh by 100% at department stores, whereas it was distributed as fresh only by 75% and the rest part was distributed as frozen or combination of fresh and frozen at supermarket. Consumers at department stores were most unsatisfied with drip loss whereas consumers at supermarket were most unsatisfied with freshness of chicken. At present, more than 89% broiler are selling by their weight unit of a bird (called as ho) in department stores, food chain stores and supermarket. The marketing periods were 3 days at department stores and 4days at supermarket. Most broiler marketing managers in stores such as 80% those at department stores, 60% those at food chain stores and 50% those at supermarkets were favored for the grading system based on quality of raw chicken. The broiler marketing managers at department stores and food chain stores preferred to the grading system evaluated with 2 quality grades and those at supermarkets preferred to the grading system evaluated with 3 quality grades if the grading system is to be established. The drumsticks and drummette of broiler were the most popular portions when compared to the other portions. In conclusion, marketing stores as well as consumers demanded to produce the best quality chicken by the grading system based on quality. Therefore, the quality improvement is the most important factor to increase consumer preference in chicken production.

  • This study purposes to examine direct effects of the physical environments and indirect effects of the satisfaction with life on the settlement consciousness of the aged, using the raw data of 2015 Busan Social Survey. The 5,324 cases were selected from the raw data of those more than 65 years old. The results were as following: (1) When age, spouse with/without, diseases with/without, length of residence, and number of communicating persons were controlled, the satisfaction with housing, the number of cultural facilities, and public transportation availability affected directly on the settlement consciousness of the aged, but the levels of the satisfaction with the number of parks were not directly correlated with it. (2) The satisfaction with housing and public transportation affected indirectly on the settlement consciousness through the satisfaction with life. That is, the satisfaction with life had mediating effects on the two variables. (3) The satisfaction with parks did not affect directly on the settlement consciousness, but it affected on the settlement consciousness through the satisfaction with life. That is, the satisfaction with life shows the complete mediating effects on the settlement consciousness. These results imply that the physical environments such as housing, cultural facilities, public transportation affect on the aged's settlement consciousness so that they should be age-friendly.

  • Background: This study aimed to investigate allergic rhinitis and the relationship between allergic diseases, such as asthma and allergic rhinitis, and dental caries and periodontal disease using the raw data from third year of the 6th Korean National Health and Nutrition Examination Survey. Methods: A total of 3,729 subjects aged over 30 years who underwent examination for allergic diseases and an oral health checkup were selected. The data were analyzed using SPSS IBM SPSS ver. 25.0 (IBM Corp., USA). Composite sample cross correlation and composite sample logistic regression analyses were performed using the composite sample general linear model. Results: On examining the socioeconomic characteristics of the subjects suffering from allergic disease and the relationship between allergic disease and oral health, allergic rhinitis was more frequently found in younger subjects with a higher level of education. Periodontal disease and dental caries were more frequent among female, older age groups, lower income earners, and subjects with a lower level of education (p<0.05). On examining the relationship between the oral health characteristics of the subject and allergic diseases and oral health, allergic rhinitis was more common in subjects with a good oral health status perception than those who answered "bad" to the oral health status question. The community periodontal index of treatment needs (CPITN) score was higher in subjects who answered "poor" to the oral health status question, lower frequency of brushing, and higher in subjects using secondary oral hygiene products; the decayed, missing and filled teeth (DMFT) index was higher in subjects with a perception of poor oral health status (p<0.05). The DMFT index was high in the asthma group, and the CPITN score was high in the group who answered "no" to allergic rhinitis. Conclusion: There is a relationship between asthma and allergic rhinitis and the DFMT index and CPITN score. Corresponding oral programs for allergic patients need to be developed.

  • The objective of this study is to examine the perception of golfwear and related trends based on major keywords and associated words related to golfwear utilizing big data. For this study, the data was collected from blogs, Jisikin and Tips, news articles, and web $caf{\acute{e}}$ from two of the most commonly used search engines (Naver & Daum) containing the keywords, 'Golfwear' and 'Golf clothes'. For data collection, frequency and matrix data were extracted through Textom, from January 1, 2016 to December 31, 2017. From the matrix created by Textom, Degree centrality, Closeness centrality, Betweenness centrality, and Eigenvector centrality were calculated and analyzed by utilizing Netminer 4.0. As a result of analysis, it was found that the keyword 'brand' showed the highest rank in web visibility followed by 'woman', 'size', 'man', 'fashion', 'sports', 'price', 'store', 'discount', 'equipment' in the top 10 frequency rankings. For centrality calculations, only the top 30 keywords were included because the density was extremely high due to high frequency of the co-occurring keywords. The results of centrality calculations showed that the keywords on top of the rankings were similar to the frequency of the raw data. When the frequency was adjusted by subtracting 100 and 500 words, it showed different results as the low-ranking keywords such as J. Lindberg in the frequency analysis ranked high along with changes in the rankings of all centrality calculations. Such findings of this study will provide basis for marketing strategies and ways to increase awareness and web visibility for Golfwear brands.
