Objectives: The study examined the status on the use of nutrition labeling and nutrition claims among university students as well as the diet quality and nutritional status using the nutrition quotient (NQ) according to the use of nutrition labeling and claims. Methods: A cross-sectional survey was conducted on university students (86 males and 131 females) from March to April in 2019 in Chungbuk area. Results: The percentage of subjects who reported that they recognized nutrition labeling was 80.2% of the total, and 63.8% of them indicated that they used nutrition labeling for their food choices. In addition, 22.6% of the total subjects said that they used nutrition claims. The group of subjects using nutrition labeling showed significantly higher mean scores in balance (P < 0.01), diversity (P < 0.05), moderation (P < 0.01), and dietary behavior (P < 0.001) along with higher mean NQ score (P < 0.001) compared to the group not using nutrition labeling. The group using nutrition claims had significantly higher mean scores in balance (P < 0.001), diversity (P < 0.01), moderation (P < 0.001), and dietary behavior (P < 0.001) as well as total NQ scores (P < 0.001) compared to the group not using nutrition claims. The group of subjects using both nutrition labeling and nutrition claims showed significantly higher mean NQ scores than the group of subjects using either nutrition labeling or nutrition claims (P < 0.05). Conclusions: In this study, university students' use of nutrition labeling and nutrition claims appeared to be related to their diet quality and nutritional status.

Antioxidant films are one active packaging technology that can extend food shelf-life through preventing lipid oxidation, stabilizing color, maintaining sensory properties and delaying microbial growth in foods. Because raw, fresh and minimal processed foods are more perishable during storage or under display conditions than further processed foods, they rapidly lose their original quality. Foods are susceptible to physical, chemical, and biochemical hazards to which packaging films can be effective barriers. Although films incorporated natural (tocopherols, flavonoids and phenolic acids) or synthetic antioxidants (BHT, BHA, TBHQ, propyl gallate) have been extensively tested to improve quality and safety of various foods, food applications require addressing issues such as physical properties, chemical action, cost, and legal approval. Increased interest in natural antioxidants as substitutes for synthetic antioxidants has triggered research on use of the new natural antioxidants in films and coatings. Use of new components (phytochemicals) as film additives can improve food quality and human health. The biosynthesis of plant phenolics can potentially be optimized by active coatings on harvested fruits and vegetables. These coatings can trigger the plants natural proline-linked pentose phosphate pathway to increase the phenolic contents and maintain overall plant tissue quality. This alternate metabolic pathway has been proposed by Dr. K. Shetty and is supported by numerous studies. A new generation of active food films will not only preserve the food, but increase food's nutritional quality by optimizing raw food biochemical production of phytochemicals.

In recent years, large-scale and high-density use of LED on facades has exposed some disadvantages, such as light pollution, high energy consumption, unsustainability, and poor interactivity. Because of the development of smartphones and augmented reality (AR), AR has emerged as a new technology available to users to interact with the media façade. As an augmented reality app for public space, the AR map app can superimpose virtual images on the surface of a building to form an AR media façade, which can be applied in the fields of navigation, advertising, interactive public art, smart retail, etc. This study establishes the variables influencing usage intention and the consequent outcomes of Huawei AR map app and uses the technology acceptance model (TAM) to discuss their relationship. Results show that consumer innovativeness, information quality, and design quality have a strong influence on perceived ease of use. Information quality has a positive impact on perceived usefulness, but design quality has a weak influence. Also, the design quality of Huawei AR map app and consumer innovativeness have a higher effect on perceived enjoyment than information quality. Users' usage attitude and perceived usefulness when using Huawei AR map app are key factors determining their usage intention. This study inspires city planners, architects, developers, and designers of AR apps that augmented reality can partly replace media façade, and that investment in augmented reality will achieve significant sustainable economic and social benefits.

This paper pointed out major problems of land use regulation policy surrounding Paldang Lake as follows: (1) inefficient management system, (2) inconsistent administrative management, (3) illogical selection of regulated area, (4) contradictory present system, and (5) controversial discharge control. Several regulation laws for the land-use surrounding Paldang Lake caused confusion of application and inefficiency of management. Amendment of regulation laws made it possible that the regulated area was developed, which resulted in the deterioration of water quality. In addition, successive regulations without scientific implementation overexpanded regulated area and focus on the discharge concentration of contaminated sources stimulated development of small size sources. To overcome these problems, we suggested reestablishment of regulated area, differentiation of regulation amendments, and flexibility in the application of regulation. It is necessary to arrange regulated area based on the efficient land use management and scientific implementation and then to mitigate land use regulation under the sustainable development. For the flexible application of regulation, it is required to amend the rule in response to the change of environmental condition and development of environmental techniques.

Purpose: This study examined the importance and satisfaction of consumer's perception of the information delivery format of products and services required and recommended by KS A ISO / IEC Guide 13: 2003 and KS A ISO / IEC Guide 37: 2003. Methods: In this study, the importance and satisfaction of clarity, principles of information transfer, how to use expressions and technical terms, and technical terms, warning signs, and durability were investigated. Results: The t-test analysis of the importance and satisfaction of the Writing Rules of the product user guide showed that all items had statistically significant differences. The importance of the writing rules of the product user guide for the use of the product was in the order of warning signs (4.423), how to use expressions and technical terms (4.215), principles of information transfer (4.163), clarity (3.914), and finally durability (3.851). Conclusion: Among the 'explanation,' 'instruction' and 'warning' functions of the Product User Guide, the consumer uses the manual to identify the inherent dangers and misuse of the product. Besides, since the life of the product is prolonged, the Product User Guide also needs to improve the quality of the cover or paper so that it can use for a long time.

Purpose Quality control used in laboratory help to sustain precision and accuracy consistently to ensure the Diagnostic and treatment for medical employee. To perform an evaluation in statistical manner, it is recommended to use different quality control material than calibrator from manufacturer, quality control material must include analyzed concentration perimeter, must use more than two different concentration materials and recommended to use materials to indicate the concentration in clinical use. However, currently used quality control material has limit of evaluation due to unconsidered concentration or improperly used to get clinical importance data. Therefore, we compared the value of quality control, DIACON Hormone Level 1, 2, 3 (Scantibodies, USA) and DIACON Tumor Level 1, 2, 3 which applied to clinical concentration range. Materials and Methods DIACON Hormone Level 1, 2, 3 (Scantibodies, USA) and DIACON Tumor Level 1, 2, 3 (Scantibodies, USA) that used materials and methods test to compare the result from five RIA testing institution and one institution that used Elecsys (ROCHE) and Architect (ABOTT) for each level. The reagent RIA kit that used in this experiment is followed by Table 2 and 3. Test has performed by instruction itself and follow by instruction. Results Among DIACON hormone result of twenty four items, level 1 have three items, level 2 have four items and level 3 have five items were out of manufacturer set up range based on the average value. Among DIACON tumor result of thirteen items, level 1 have three items, level 2 have four items and level 3 have five items were out of manufacturer set up range. Other result were inside of manufacturer range. Conclusion For quality control material, it is widely available in market, but it is limited for normal range which is only concerned in improper clinical value and difficult to evaluate important concentration area in terms of clinical analyze. In this experiment, we evaluate Hormone twenty three items and Tumor thirteen items with DIACON Hormone and Tumor (Scantibodies, USA) to resolve this limit and we could observe that it ca be substituted and used.

The objectives of this study are to explain the use of media materials in school health education with other related factors in elementary, middle, and high schools in Korea. The data were collected by questionnaires from June to September in 1998. The number of subjects were 294 school nurses. The PC-SAS program was used for statistical analysis such as percent distribution, chi-squared test, spearman correlation test, and logistic regression. The use of media materials in health education has become extremely common. Unfortunately, much of the early materials were of poor production quality, reflected low levels of interest, and generally did little to enhance health education programming. A recent trend in media materials is a move away from the fact filled production to a more affective, process-oriented approach. There is an obvious need for health educators to use high-quality, polished productions in order to counteract the same levels of quality used by commercial agencies that often promote "unhealthy" lifestyles. Health educators need to be aware of the advantages and disadvantages of the various forms of media. Selecting media materials should be based on more than cost, availability, and personal preference. Selection should be based on the goal of achieving behavioral objectives formulated before the review process begins. The decision to use no media materials rather than something of dubious quality usually be the right decision. Poor-quality, outdated, or boring materials will usually have a detrimental effect on the presentation. Media materials should be viewed as vehicles to enhance learning, not products that will stand in isolation. Process of materials is an essential part of the educational process. The major results were as follows : 1. The elementary schools used the materials more frequently. But the production rate of media materials was not enough. The budget was too small for a wide use of media materials in school health education. These findings suggest that all schools have to increase the budget of health education programs. 2. Computers offer an incredibly diverse set of possibilities for use in health education, ranging from complicated statistical analysis to elementary-school-level health education games. But the use rate of this material was not high. The development of related software is essential. Health educators would be well advised to develop a basic operating knowledge of media equipment. 3. In this study, the most effective materials were films in elementary school and videotapes in middle and high school. Film tends to be a more emotive medium than videotape. The difficulties of media selection involved the small amount of extant educational materials. Media selection is a multifaceted process and should be based on a combination of sound principles. 4. The review of material use following student levels showed that the more the contents were various, the more the use rate was high. 5. Health education videotapes and overhead projectors proved the most plentiful and widest media tools. The information depicted was more likely to be current. As a means to display both text and graphic information, this instructional medium has proven to be both effective and enduring. 6. An analysis of how effective the quality of school nurse and school use of media materials shows a result that is not complete (p=0.1113). But, the budget of health education is a significant variable. The increase of the budget therefore is essential to effective use of media materials. From these results it is recommended that various media materials be developed and be wide used.

The purpose of this study was to investigate the association between dietary quality and smart device use among middle school students. A total of 330 middle school students (171 boys and 159 girls) residing in Incheon participated in this questionnaire survey in June 2018. The boys and girls were divided into two groups according to their daily use time of smart devices: less than 3 hours a day (<3 hours) and 3 hours or more a day (≥3 hours). Eating habits and dietary quality were assessed using a nutrition quotient for adolescents (NA-Q). For boys and girls, higher consumption frequency of white milk was significantly associated with less time spent using a smart device. For boys, a higher number of vegetable dishes and eating frequency of breakfast were significantly associated with the less time spent using a smart device. For girls, higher consumption frequency of processed beverages, ramyeon, and street foods was significantly associated with more time spent using a smart device. For boys and girls, those who spent more time using a smart device had significantly lower NA-Q scores, indicating low dietary quality. To sum up, more time spent using a smart device among middle school students may be associated with lower dietary quality. These results suggest the need to provide a nutrition education program and guidelines to students who use smart devices for a long time.
