According to the change in media environment, a support plan for local broadcast has been required. In terms of legal and institutional support for the development of local broadcast, the enactment of special Act for local broadcast has become a breakthrough. In this point of view, we analyzed the performance and the limitation of the special Act. As a literature research, analyzing the literature and related-ordinances, we have sought legal and institutional support plans for the local broadcast. As a result, with the Local Broadcast Development Council being in charge of legislative right and responsibility, a plan to empower them to have legal and institutional authority should be drawn; another plan to secure independence in operating a fund and to promote the capability to produce local broadcast programs and the distribution system should be drawn; the other elaborate plan for the locality index that assesses the locality is required. Local broadcast should be on a way to secure not only public interest and concern but locality and diversity; legal and institutional plans should be sought.

This study examined awareness and information acquisition behavior regarding food hygiene and safety of university students to improve safe dietary practices and to get basic information to develop educational materials for food safety. It was conducted among 276 university students of Qingdao University and Liaocheng University in Shandong province, China through a self-administered questionnaire. Data were analyzed by SPSS Windows V.19.0. To describe characteristics of the respondents, frequency distributions were used. In addition, t test, one-way analysis of variance and Duncan's multiple range tests were conducted. The results were as follows: The respondents were generally interested in food hygiene and safety. However, the level of awareness regarding the food hygiene and safety system in China was not high. Almost forty-five percent of the respondents did not think that foods produced and distributed in China were safe. For the reasons for their distrust, most of the students replied that they did not trust the safety 'because of distrust for hygiene of the food process', followed by 'because of distrust for food distribution' and 'because of excess or illegal use of food additives on food process'. The respondents answered for the concern level toward food hygiene and safety foodborne disease threatened food safety the most, followed by heavy metal contamination and endocrine disruptors. The respondents acquired most information from electronic media including TV and radio. Most of the students wanted to participate in food hygiene and safety education. Finally, when they found hazardous or foreign materials in food the most frequent reaction was 'paying attention in the next purchase', followed by 'notifying others', and 'letting it go this time but never buying that product in the future'.

This study examined images typical to this city and explored ways to develop cultural products using these images. Researchers reviewed literature about fashion cultural products and related previous research, and then conducted a closed-ended survey to analyze universal fashion preferences. For the examination material, such a way was used as information data base and network review inside and outside the country, dissertation screen, and published media including separate volumes. The following are considering points in the developing process. First, the study identified design, color, price, practicality and quality as factors that should be taken into consideration when using the image of Gangneung. In particular, it determined that the image needs to reflect a modern sensibility while maximizing its representation of local culture. Second, Gangneung's symbolic image should incorporate the sea, Gyeongpo, and coffee. In other words, the sea, Gyeongpo, and coffee should receive top symbolic priority. Third, from a development perspective, the most appropriate items for displaying the image include t-shirts, keychains, umbrellas, or other accessories, since these items are easily available in terms of price. In sum, this study highlighted the necessity of reconsidering Gangneung's currents ymbolic image, suggesting that a new image should be developed. Developing a typical fashion cultural product image will enrich Gangneung's cultural industry and the distribution of newly designed products will improve the localeconomy.

The $^1H$ NMR chemical shifts and coupling constants for ${\alpha}$-, permethyl-${\alpha}$-, ${\beta}$-and permethyl-${\beta}$-cyclodextrins in neutral aqueous media were assigned based on the 470MHz spectra. In order to obtain accurate chemical shifts and coupling constants the experimental spectra were analyzed with the Raccoon spin simulation program. The rotamer distribution around the$C_{5-}C_6$ bond of the cyclodextrins evaluated from the coupling constants of $J_{56a}$ and $J_{56b}$. In our calculation of the ${\alpha}$-, and ${\beta}$-cycliodextrin showed that gg conformers were most favorable form and tg conformers were least favorable form. It is very interesting to note the changes in $J_{56a}$, $J_{56b}$ coupling constants of permethylated ${\alpha}$- and ${\beta}$-cyclodextrins from unmodified one. The gg conformers were more increased than unmodified one and instead of tg conformers gt conformers were least favorable one upon methylation.

Environmentally-friendly acrylic resin particles having the diameter between $0.1\;and\;1\;{\mu}m$ were prepared using non-aqueous dispersion (NAD) polymerization technique. The first step is to prepare the stabilizer and the next step is the NAD polymerization by dropping an acrylic monomer to stabilizer dispersed in organic media. To obtain a NAD resin with proper level of viscosity, it fumed out that stabilizers having sufficient viscosity such as 1000 cP need to be used, for which the stepwise feeding of monomer and initiator was necessary. It was necessary to put proper amount of stabilizer, but no more increase in viscosity was observed when more than that amount of stabilizer was added. Choice of proper monomers considering solubility parameter was essential to avoid the bimodal particle size distribution in the NAD resin product.

This study aims to provide theoretical base in criminal law for engineers in the viewpoint of jurists to encourage interdisciplinary studies on cyber crimes. Apart from seriousness of discussion on torrent cyber crimes, a good effect of the internet networks such as sharing of information has bee emphasized while the evil influence of its side effect has been neglected. Therefore, this study suggests that we need to consider reinforcement of cyber ethics, and legal mind of IT technicians, strict security by managers, active efforts to develop legitimate contents by managers of web hardware and P2P, and reinforcement of punishments against crimes by internet users. And this study approaches new norms on computer and cyber crimes in interpretational sense of criminal law, and provides the theoretical base of the criminal law focusing on traditional theories, assumptions, and precedents involved in regulations against computer virus distribution.

The purpose of this study was to investigate whether elementary school parents' environmental literacy varied according to independent variables, to verify specific variables that affected their environmental literacy, and to analyze the correlation between elementary school students' and their parents' environmental literacy. Twelve elementary schools in Seoul and Gyeonggi-Do were chosen for purposive sampling. 342 questionnaires were used for analysis among the 350 questionnaires collected during the study, and their environmental literacy was measured through 55 questions consisted of 12 items for knowledge category, 22 for attitude category, 5 for behavior category, and 3 for skills category with 16 demographic variables. Statistical analysis was conducted on each of the variables that make up environmental literacy through mean t-test, F-distribution, Scheffe test, and Pearson correlation. The results of this study were as follows. (1) there is the difference according to age and career in parent's actual environmental literacy, but there is no difference in geneder, birthplace, residential type, religion and income. The parents in forties scored significantly higher than parents in thirties in subdomains of environmental skill and environmental interest in environmental literacy. And the parents with bachelor's degree scored significantly higher than parents with at least a high school diploma in subdomains of ecological knowledge, knowledge on environmental problems & issue, environmental skill and environmental behavior. (2) the most influential media on parents' environmental literacy is TV, then newspaper, internet and book follow. (3) the correlation between environmental crisis and environmental interest is the highest, but the mainly negative correlation is analysed between knowledge subdomains and other subdomains. (4) there is the correlation between elementary school students' and their parents' environmental literacy.

Self-organized nanogels were prepared from pullulan/biotin conjugates (PU/Bio) for the development of an effective anticancer drug delivery system. The degree of biotin substitution was 11, 19, and 24 biotin groups per 100 anhydroglucose units of pullulan. The physicochemical properties of the nanogels (PU/Bio1, 2 and 3) in aqueous media were characterized by dynamic light scattering, transmission electron microscopy, and fluorescence spectroscopy. The mean diameter of all the samples was less than 300 nm with a unimodal size distribution. The critical aggregation concentrations (CACs) of the nanoparticles in distilled water were $2.8{\times}10^{-2},\;1.6{\times}10^{-2}$, and $0.7{\times}10^{-2}mg/ml$ for the PU/Bio1, 2, and 3, respectively. The aggregation behavior of the nanogels indicated that biotin can perform as a hydrophobic moiety. To observe the specific interaction with a hepatic carcinoma cell line (HepG2), the conjugates were labeled with rhodamine B isothiocyanate (RITC) and their intensities measured using a fluorescence microplate reader. The HepG2 cells treated with the fluorescence-labeled PU/Bio nanoparticles were strongly luminated compared with the control (pullulan). Confocal laser microscopy also confirmed internalization of the PU/Bio nanogels into the cancer cells. Such results demonstrated that the biotin in the conjugate acted as both a hydrophobic moiety for self-assembly and a tumor-targeting moiety for specific interaction with tumor cells. Consequently, PU/Bio nanogels would appear to be a useful drug carrier for the treatment of liver cancer.

The main objective of this paper is to examine the applicability of Linan and Chen's entrepreneurial intention model (EIM) in predicting the entrepreneurial intention. EIM is an adaptation of the Theory of Planned Behavior that focuses on entrepreneurial intention and hypothesizing slightly different patterns of relationship with regards to subjective norms. The model also includes human capital and demographic factors. Snowball sampling method was used to collect data using the entrepreneurial intention questionnaire (EIQ) through several social media platforms. The survey indicates that the overall entrepreneurial intention of Saudi students is high (mean = 5.41). Eight out of the seventeen hypothesized relationships were found to be significant. Among the demographic variables, gender-personal attitude was significant whereas self employment experience and years of business education were found to be significantly related with perceived behavioral control. The statistical analysis using partial least square structural equation modelling validated the model. All the three antecedents of entrepreneurial intention were significantly related with entrepreneurial intention. The results of this study will help policy makers to get deep understanding into the phenomenon of entrepreneurship among Saudi university students and thereby develop a conducive environment. This study also validates the entrepreneurial intention model in a different cultural context.

The Semantic Web has the objective of developing universal media in which machine-processable semantic information can be represented and shared, and it is therefore important to distribute ontologies that represent this kind of semantic information to the Web and make them available to multiple parties. However, the current ontology authoring tools are not operating on the Web, which makes it difficult to distribute ontologies directly to the Web and to create and edit them collaboratively with other people. This paper proposes a framework that facilitates the ontology construction and sharing, realizing easy distribution of ontologies to the Web. Wiki is one of the frameworks for collaborative construction and sharing of knowledge on the Web, and Wiki contents consist of natural language texts and simple markup language for visualization. For better collaboration in creating and sharing ontologies, this paper suggests the Semantic Wiki that embodies the Semantic Web features to the existing Wiki system. The Semantic Wiki framework facilitates the collaboration in ontology co-authoring and sharing for people, and at the same time, makes it possible for the agent software to easily manage the ontology information. Eventually, the Semantic Wiki system accomplishes various tasks including the semantic view, the semantic navigation, and the semantic query.
