Proposing value‑based technology acceptance model: testing on paid mobile media service

Song‑yi Youn,이규혜 한국의류학회 2019 Fashion and Textiles Vol.6 No.1

Rapid growth of online media markets among world populations led to attempts by companies to exploit mobile services as part of business planning practices. Relatedly, this study examines adoption of paid mobile media service (i.e., Amazon Prime Video) as a source of new information and communication technology with online-offline integrated mobile services. The study’s main objective is to identify a technology acceptance model from the perspective of consumer experiences of value perceptions. This study proposed a value-based technology acceptance model, deriving from classic variables related to technology acceptance with regard to relevant consumer value perception literature. The proposed model examined effects of positive and negative experiences of value perceptions on consumers’ beliefs about paid service which explained future use of the paid service. Results indicated that consumers’ positive experiences—social, emotional, and functional values—derived from using mobile media services positively explained consumers’ belief of the usefulness of the paid mobile media service. Consumers’ negative experiences with technological barriers negatively influenced consumers’ beliefs with regard to the ease of use for paid mobile service, while price risk negatively influenced perceived usefulness. Consequently, consumers’ perceptions of ease of use and usefulness related to using the paid service positively influenced behavioral intention for continuous use of the paid mobile media service.

In Vitro Antiviral Activity of Ribavirin Against Severe Fever with Thrombocytopenia Syndrome Virus Myung Jin LEE1, Kye-Hyung KIM1, Jongyoun YI2, SuJin CHOI1, Chung-Jong KIM1, Nak- Hyun KIM1, Kyoung-Ho SONG1, Pyoeng Gyun CHOI1, Ji-Hwan BANG1, Wan Beom PARK1, Eu Suk KIM1, Sang-Won PARK1, Hong Bin KIM1, Nam Joong KIM1, Myoung- Don OH1 Seoul National University College of Medicine, Korea1, Pusan National University School of Medicine, Korea2 Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

Hydrodynamic characteristics of gas-solid flow has been analyzed by adopting the static pressure drop method in circulating fluidized beds. Pressure drop has been measured in the test section of the riser(0.1m IDx3.5m Height). The dried and filtered air was injected into the column through the perforated type distributor. Polyetylene powder whose density is 920 kg/㎥ and mean diameter is 454 ㎛ was used as a solid phase. The pressure drop slightly increased in the turbulent fluidized regime and rapidly decreased because of decreasing of solid hold-up in the fast fluidization regime with increasing superficial gas velocity. The slip velocity that is relative velocity between gas and solid velocity increased in the turbulent fluidized regime and decreased in the fast fluidized regime with increasing the superficial gas velocity.

This study was purposed to explore children's development in the theory of mind. Children of age 7, 9 and 11 explained others' good and bad behaviors, and answered to questions about 'mind' and 'heart' Children's behavior explanations with internal factors, including traits and mental states, were scored and analyzed. The responses of mind-related knowledges were categorized and compared by age. Results showed that children's intemal explanations were not different with age, and most of the children explained intemally for others' bad behaviors more than for good ones. Secondly, children conceptualized cold-minded 'mind' and hot-minded 'heart' differentially, but showed developmental differences in mind-related knowledges. It was hard for the younger children to explain 'mind' and 'heart'. Children came to construct their knowledge with age; 'mind' including cognitive monitoring, and 'heart' working outside the personal emotions.

조선후기의 사회구조적 변화와 대원군의 정책

The purpose of this paper is to analyze and evaluate changes in social structure in the latter period of Chos?n and Daewongun's policies. During his rule, externally, the World Powers were eager to expand their imperialistic policies. Internally it was time for Chos?n to choose a new direction in history, largely due to the changes in the social structure. From an integrative point of view on structure and act rather than dualistic point, the paper examined the structure of ideology, status, agriculture, and commerce in the later Chos?n and then examined the relations between Chosen and Chung, between Chos?n and Japan, and between Chos?n and Western powers, respectively. Under such circumstance, in 1863, King Kojong ascended the throne Cheoljong and, immediately, Daewongun took the reigns of government. He tried to clean up deep-rooted evils caused by royal-married families(Sedojunchi), and to rule over the nation flexibly enough to accommodate various social changes. Accordingly, he promoted various policies in order to establish a new domestic order by way of overall social reforms. politically, Daewongun solidified his power basis and adopted merit system to allow more opportunities for the talent. His policies may be evaluated by three criteria - the will of ruler, support base, and the atmosphere of the times. Daewongun met two necessary conditions: leader's will on reform and possession of supporter groups. Nonetheless, his reformative policies can be evaluated as an half success because of premature social atmosphere to accommodate his reformative will. Thus, we come to conclusion that for the successive promotion of Daewongun's policies the three conditions must be worked out on mutual balance.

開化期의 學術誌에 나타난 韓國政治思想에 관한 硏究

宋二朗 東亞大學校 1981 東亞論叢 Vol.18 No.1

The formation of modern Korean political thoughts may be said to have been established with, mainly, a view to self-defending and self-reformation against the impacts of the western material and technical civilization that had come into the nation since the nineteenth century. Therefore, the success of the formation of the modern poltical thoughts was possible only when the nation maintained both national identity and modernization that do not usually accord with each other characteristically. From this point of view, we may say that roles of academic journals published between 1905 to 1910 were very important because, Firstly, they served to create modern nationalism. The advocation of recovering sovereignty, such as they had done, served as the unifying point of the people that has homogeneous ideology rather than simply returning to the absolute monarchy we had in the past. Secondly, they contributed to forming modern democratic thoughts. These journals asserted that losing sovereignty meant not only collapse of the monarchy itself, but also the self-forfeit spirit of the people. Therefore, the journals emphasized education and industry as the only possible way to awaken people to reality. At the same time, these journals advocated adopting democratic political system into the nation by guaranteeing freedom and equality of the people. Thirdly, they contributed to popularizing modern political thoughts among people. They attempted forming political thoughts of the national identity and selfdetermination by gradual practices of modernizing people's way of thinking through education. Fourthly, they contributed to unifying national identity and modern progressivism. The movement of nationalism in Korea, like western one, influenced people with unifyed concerted idea of the people which gave an impetus to executing democracy. For these reasons, the roles and activities of these journals during the enlightenment period strongly influenced in forming modern political thoughts in the nation by arousing consensus among all the levels of people through overcoming limitation set on the traditional functions of the mass media and greatly influenced in forming the idea of 3·1 Independent Movement in 1919 finally.

This study is trying to detail things about North Korea through the legend of it. The legend is a kind of belief which is not based on the truth. The political legend is simply a fiction about things political. The system of North Korea has kept nervous since the beginning. As a result, it has focused on keeping the system rather than develops the country. This structural-character caused the legend. Especially the legend in the system of North Korea played the definite role in keeping the system of kim, IL-Sung and electing the successor.

자이오머(Giomer)는 레진강화형글라스아이오노머에 견줄 만큼 불소방출량이 많다고 하나, 우식예방 효과에 관한 연구들이 많지 않아 임상적용에 대한 근거가 부족한 실정이다. 본 연구는 자이오머(BF 군)를 포함하여 레진강화형글라스아이오노머(FF 군), 콤포머(DA 군)와 대조군인 콤포짓(FZ 군)의 우식억제 효과와 주변 치질로의 불소침투 양상을 비교하기 위하여, 공초점레이저주사현미경과 전자탐침미세분석기를 이용하여 각 수복재의 우식예방 효과를 비교하였으며, 다음과 같은 결과를 얻었다. 1. 수복물 주위 이차 인공우식에서 법랑질 외측병변의 깊이는 FZ 군에서 가장 깊었으며, BF 군이 가장 작게 나타났다(p<0.05). 2. 수복물과 법랑질 계면에 나타난 탈회억제층의 두께를 관찰한 결과 FZ 군이 가장 작게 나타났으며, FF, DA, BF 간에는 유의성 있는 차이를 보이지 않았다(p<0.05). 3. 법랑질에 침투된 불소농도는 BF, FF, DA의 순으로 높게 나타났다. 4. 상아질에 침투된 불소농도는 DA, BF, FF의 순으로 높게 나타났으며, 이는 상아질-수복물의 접착 계면에 영향 받는 것으로 보인다. The purpose of this study was to evaluate the effect of light cured fluoride-releasing materials on the inhibition of demineralization. In addition, the pattern of fluoride uptake of adjacent tooth structure was analyzed with EPMA. Eighty intact premolars were restored with Filtek Z250(control group, composite), Fuji Filling LC(RMGI), Dyract AP (compomer) and Beautifil II(giomer). Restored teeth were stored in distilled water for 30 days. Thensixty teeth(n=15) were exposed to demineralizing solution(pH 4.3). Demineralized teeth were bisected and polished. The specimens were observed with confocal laser scanning microscope. The depth of outer lesion and the thickness of inhibition zone were measured. Remained twenty teeth(n=5) were bisected for fluoride uptake analysis. The fluoride analysis were taken at enamel-restoration interface and dentin-restoration interface by electron probe micro-analyzer. The results are as follows: 1. The depth of outer lesion of Fuji Filling LC, Dyract AP, Beautifil II was shallower than that of Filtek Z250 at the margin of restoration(p<0.05). 2. The thickness of caries inhibition zone of Fuji Filling LC, Dyract AP, Beautifil II was greater than that of Filtek Z250 at the margin of restoration(p<0.05). 3. Fuji Filling LC, Dyract AP, Beautifil II groups showed the greater fluoride uptake into enamel and dentine around restoration than Filtek Z250 group. 4. In dentin the difference of fluoride concentration were greater than in enamel, and Dyract AP showed the greatest fluoride concentration in dentin.

Les textes de M. Duras, de Ch'oe Yun permettent au lecteur de de´couvrir que des voix se correspondent, d'une ge´ne´ration a` l'autre, d'un continent a` l'autre. La re´ite´ration de certains the`mes et le retour obsessionnel de quelques images manifestent des tendances analogues dans ces deux univers romanesques. La migration entre deux environnements culturels tout a` fait diffe´rents, dans le ve´cu de M. Duras, correspond, d'une certaine fac¸on, a` l'influence de la litte´rature franc´aise dans celui de Ch'oe Yun. La comception spe´culaire pre´vaut dans le traitement de l'espace dans les textes de Marguerite Duras et de Ch'oe Yun. Les lieux ouvrent sur un re´seau de correspondances complexes et re´versibles avec les personnages. Ils fonctionnent comme des e´le´ments d'identification de ces figures flottantes qui fro^lent l'anonymat ou ils disparaissent sous une configuration humaine. De me^me que Lahore n'est autre que le vice-consul, la jeune fille de La`-bas, sans bruit, tombe un pe´tale se re´duit au double de Kwangju. Ce processus de de´placement et de substitution e´tablit un syste`me d'analogies et d'interfe´rences entre les corps et les lieux. Il se produit un e´change permanent qui permet d'impre´gner l'espace de signification corporelle et d'attribuer au corps une valeur spatiale. Le texte de M. Duras aime repre´senter le corps fe´minin comme espace et sa relation fusionnelle avec les lieux. Ainsi, les re´gions ou` erre la mendiante du Vice-consul s'assimilent a` son corps. Ch'oe Yun, quant a` elle, voit souvent le corps comme une matie`re poreuse dans laquelle s'enfouissent les e´ve´nements qui y laissent leur empreinte. Le corps de la jeune fille folle dans La`-bas, sans bruit, tombe un pe´tale, se pre´sente ainsi comme le lieu de re´sonance ou` chaque incident se re´percute en e´chos. Les images inde´cises ou mobiles marquent souvent les lieux. Ainsi, les frontie`res spatiales du dedans et du dehors, de l'inte´rieur et de l'exte´rieur s'abolissent chez M. Duras et Ch'oe Yun. Les indications ge´ographiques qui n'ont gue`re de valeur indicielle conjurent le mime´tique dans certains textes de M. Duras et de Ch'oe Yun. Ce mode de pre´sentation de l'espace favorise l'unification des lieux, aussi nombreux que disparates, et souligne la similitude d'espaces que diffe´rencient leur nom, leur forme, et leur situation. Cette configuration d'espace inscrit l'espace dans une organisation spe´culaire et maintient une inde´termination autour des lieux et des objets parcourus, appre´hende´s par les personnages. Dans cette perspective, Hiroshima, lieu de concentration de la douleur, se re´duit au reflet de Nevers et le village natal de Mains Vertes correspond au Po^le Nord.. La configuration des lieux corporels, l'identite´ spatiale des personnages et le brouillement des limites de l'espace chez nos e´crivains te´moignent, d'une certaine fac¸on, du grand re^ve archai¨que de retour au corps maternel. Ainsi, refus des formes e´tablies, ambigui¨te´ fondamentale, les textes de M. Duras et de Ch'oe Yun font retentir une voix d'une inconcevable contre´e, inte´rieure a´ soi mais inconnue. Ce lieu de l'Autre est l'espace d'une parole fe´minine ou´ coexistent l'he´te´roge´ne´ite´ pulsionnelle et la musique maternelle que le langage n'a pas su retenir.

This study was a research study to find out the real picture and practice of student obesity control by primary, middle and high school nurses. The study sampled 196 school nurses working in the Busan City and Northern Gyungsang Province, who agreed on the purpose of the study. When it comes to the study process, at the meeting of the whole school nurse, the researcher explained the purpose of the study and asked them to complete questionnaires and return on the spot. The study is designed to provide basic data for school nurses in field to systematically and efficiently control student obesity by examining perception of school obesity control and the real picture of practice of obesity control as well as its problems. The study used SPSS 10.0 to analyze data. The results are as follows: Annual plans about obesity control appeared significant at the primary school, 89.3%, higher than 77.3% of the middle and high school(p<0.05). Annual project evaluation showed a significant difference by regions, 56.0% of metro cities vs. small cities(p<0.01). The number of measuring weight of obese students was higher at the primary school than at the middle and high school(p<0.05). Also small cities conducted the weight measurement more often than metro cities(p<0.001). Among the health education methods for obesity, counseling appeared statistically significant(p<.01). The health education showed a significant difference in more experienced school nurses. Among the educational media, environment postings were used at the primary school, 24.0%, higher than 5.3% of the middle and high school. It showed a significant difference(p<.001). OHP or epidiascopes were used at the primary school, 36.4%, significantly higher than the middle and high school(p<.001). In addition, computer was used at the primary school, 21.5%, higher than the middle and high school(<.05). Problems of obesity education data included a lack of textbooks and programs and a short of educational media. However it didnt show a significant difference in schools or in regions. Counseling activities for obesity showed a significant difference in schools(p<.01) and in regions(p<.001). When parents with obese students were in counseling, those in their 20s used home correspondence and those in their 30s and 40s used phone call(p<.01). The rate of equipment to measure obesity was higher at the middle and high school than the primary school, showing a significant difference(p<.001). therefore, regular health education curriculums for school nurses should be systematically created to promote student health. Furthermore, it needs to make standard textbooks for health education by grades as well as by levels and to develop various educational programs and educational media.
