Article 17 and 18 of the Korean Constitution respectively prescribe the violation of individual's right to privacy and the secrecy of wire communication. Meanwhile, Article 20 of the Criminal Code provides that an act which is conducted within the ambit of laws or pursuant to accepted business practices or which does not violate the social norms shall not be punishable. In 1999, the Constitutional Court held that media reports on public matters of public figures must be given strong constitutional protection, and treated differently from reports on private matters of private figures. In accordance with the decision, the Supreme Court has expanded the scope of constitutional guarantee of freedom of expression since 2002. This study analyzes the issue of media liability for publication of illegally intercepted wire communication by a third person. Particularly, it reviews Seoul High Court's ruling on 'X-file scandal' which disclosed intercepted wire communications between notable public figures regarding a slush fund for a presidential candidate. In the light of this analysis, the study concludes that the media reporting of the intercepted communication does not violate social norms of Article 20, and therefore it is entitled to a constitutional privilege.

Monosodium glutamate(MSG) is a widely used food additive. Some reports descried its positive effect and the others, negative effect on mouse, monkey, human or drosophilid flies. Because of the conflicting reports the present investigation was undertaken to study the effects of MSG on the development of Drosophila melanogaster. The two strains of D. melanogaster, Oregon-R and Sinchon-I were used and MSG as well as cane sugar (as the second control) media were prepared by adding MSG or cane sugar at various concentrations to the standard food media for the present study. Ten flies (Male 5, Female 5) were placed in each vial and the numbers of $F_1$ flies emerged from it were counted. The results are presented below: 1. The numbers of $F_1$ flies decrease as the concentrations of MSG increase, implying that MSG has an inhibitory effect in the development of D. melanogaster. 2. The effects of cane sugar show an enhancing effect rather than an inhibitory one. 3. The numbers of $F_1$ fies produced in the Sinchon-I strain are greater than in the Oregon-R. This may be due to the difference in the length of inbred period. 4. The Muller-5 test shows a negative result, suggesting that MSG may be not mutagenic.

In this study, we established an in vitro regeneration system to maximize the recovery of leafy perilla (Perilla frutescens L. Britton) plantlets as part of developing a molecular biotechnology-based metabolic engineering program for this crop plant. Hypocotyl segments including the apical buds were used as explants for the direct production of shoots without an interim callus phase. The number of shoots produced from the apical buds peaked within 3-4 weeks, and the shoots were subsequently cultured on Murashige and Skoog (MS) media supplemented with 2 mg $1^{-1}$ benzylaminopurine (BA). Spontaneous rhizogenesis was observed after 7-10 days of culture on MS media without hormonal additives. The rooted shoots developed into normal plants in soil after hardening on distilled water for 3-4 days. The average plantlet regeneration frequency was higher for the apical buds (64.33%) than for the top (15.66%), middle (4%), and basal (1.33%) segments of the hypocotyls. This regeneration system demonstrates a capacity for high-frequency plantlet recovery and thus should be considered for use in the genetic manipulation of leafy perilla.

The present study aimed to find out the most effective instructional method for illustration to aid the $21^{st}$-century post digital generation learners in their education. Although the literature discusses government-led enactment and revision of educational policy and curriculums and research reports by the Ministry of Education and other government agencies as well as many other research articles deal with futuristic instructional methods, the instructional methods in practice have not fully changed yet. Illustration is a means of visual communication and a subject that best represent 'expressionism' and 'speed' of the post digital generation. The present study exemplifies instructional methods to establish the need for lesson plans that best suit individuality of students and for re-training instructors. Also, the feedback process with students proved that the post digital generation learned Photoshop quickly and improved creativity via image synthesis even in short-term instructions. The present findings can be possibly used as reference data for instructional methods for illustration using digital media that best suits learners of the post digital generation. This being said, further studies should delve into specific instructional methods.

In this study I selected the keyword analysis method to infer what's the components of production system. Magazine , were chosen, because they are most close media to production reality. After content analysis of , key words of main reports were programming production, institution policy, industry, technology. As for , institution policy, organization, programming production, collective action were frequently found. Even though there are some differences between two media, institution policy, industry, technology, organization keywords are very salient components regarding programming production.

Gallium is an important element in the production of a variety of compound semiconductors for optoelectronic devices. Gallium has a low melting point and is easily oxidized to give oxides of different compositions that depend on the conditions of solutions containing Ga. Gallium electrode reaction is highly irreversible in acidic media at the dropping mercury electrode. The passive film on a gallium surface is formed during anodic oxidation of gallium metal in alkaline media. Besides, some results in published reports have not been consistent and reproducible. An increase in the demand of intermetallic compounds and semiconductors containing gallium gives rise to studies on electrosynthesis of them and an increase of gallium concentration in the environment with various application of gallium causes the development of electroanalysis tools of Ga. It is required to understand the electrochemistry of Ga and to predict the electrochemical behavior of Ga to meet these needs. Any review papers related to the electrochemistry of gallium have not been published since 1978, when the review on the subject was published by Popova et al. In this study, the redox behavior, anodic oxidation, and electrodeposition of gallium, and trace determination of gallium by stripping voltammetries will be reviewed.

This paper reports a facile synthesis of new water-soluble poly(ethylene oxide) (PEO)-based amphiphilic block copolymers showing pH sensitive phase transition behaviors. The copolymers were prepared by atom transfer radical polymerization (ATRP) of methacrylamide type of monomers carrying a sulfonamide group using a PEO-based macroinitiator and a Cu(I)Br/$Me_6TREN$ catalytic system in aqueous media. The resulting polymers were characterized by a combination of $^1H$-NMR, size exclusion chromatography, and UV/Visible spectrophotometeric analysis. The micellization of the block copolymers as a drug-loading mechanism in aqueous media using fluorescein salt was examined as a function of pH. The stable micelle formation and its loading efficacy suggest that the block copolymers can be used as precursors for drug-nanocontainers.

Honey is one of the most significant ingredients in conventional food production in different regions of the world. Honey is commonly used as an ingredient in ethnic food. Beekeeping is performed in various locations as part of the local food culture and an occupation related to pollinator production. It is important to conduct beekeeping so that it generates food culture and helps regulate the regional environment in an integrated manner in preserving and improving local food culture. This study analyzes different types of environmental factors of a smart bee farm. The major goal of this study is to determine the best prediction model between the linear regression model (LM) and the support vector regression model (SVR) based on the environmental factors of a smart bee farm. The performance of prediction models is measured by R² value, root mean squared error (RMSE), and mean absolute error (MAE). From all analysis reports, the best prediction model is the support vector regression model (SVR) with a low coefficient of variation, and the R² values for Farm inside temperature, bee box inside temperature, and Farm inside humidity are 0.97, 0.96, and 0.44.

The purpose of this study is to analyze the characteristics of Korean media on the topic of archives & records management based on time-series analysis. In this study, from January, 1999 to June, 2018, 4,680 news articles on archives & records management topics were extracted from BigKinds. In order to examine the characteristics of the media coverage on the archives & records management topic, this study was analyzed to the difference of the press coverage by period, subject, and type of the media. In addition, this study was conducted word-frequency based content analysis and semantic network analysis to investigate the content characteristics of media on the subject. Based on these results, this study was analyzed to the differences of media coverage by period, subject, and type of media. As a result, the news in the field of records management showed that there was a difference in the amount of news coverage and news contents by period, subject, and type of media. The amount of news coverage began to increase after the Presidential Records Management Act was enacted in 2007, and the largest amount of news was reported in 2013. Daily newspapers and financial newspapers reported the largest amount of news. As a result of analyzing news reports, during the first 10 years after 1999, news topics were formed around the issues arising from the application and diffusion process of the concept of archives & records management. However, since the enactment of the Presidential Records Management Act, archives & records management has become a major factor in political and social issues, and a large amount of political and social news has been reported.
