This research shows the national competitiveness between Korea and China by analyzing the trade structure of both countries in IT industry. UN COMTRADE Data, from year 2005 to year 2015, has been used in this research. This study applies various means of analytical method including Trade Specification Index, Revealed Comparative Advantage, which are popular methodologies in analyzing the competitiveness of a certain industry between two countries, to our research. The summary of our study is as follows. The trade volume between two countries in IT industry has been doubled between 2005 and 2007 in the world market. As world trades grow in IT industry, both countries’ trade volume shows rapid growth in IT. However, each country shows the different pattern in growth: Chinese market can be considered as an export-driven growth market, and Korean market is like an import oriented growth market. In addition, Korea’s trade volume in IT accounted for 5% of global trade volume while Chinese market presented relatively higher proportion, over 25% in the same industry. The result of competitiveness analysis of each item in IT industry indicates that Korea’s competitiveness is highest in components and is lowest in communication device over China in 2015.

Green tea extracts, which contain flavonoids, were prepared by using various extraction methods and their effects reducing oral malodor were investigated. Flavonoids of green teas from different planting sites had seven same glycosides and five same aglycones, and their contents made no significant differences. Among the deodorants available commercially, that for toilet was much more effective than those for living room and car-interior. On the other hand, the chlorophylls and the tannins from green teas also had strong deodorant effects, but glycerine and water which were used as extracting solvent showed negligible effects. Four solvents showing no problem on food processing in Korea were used to get the extracts of green teas, and effects of those extracts on reducing a typical malodor, methyl mercaptan, were comparde via in vitro tests. The best extract was attained by using EtOH-water, and hot water(80℃), glycerine-water, warm water(25℃) were better in order. However, the extracts using EtOH-water, hot water or warm water included lots of caffeine and tannin which had bitter and astringent tastes, respectively. On the other hand, glycerin-water extracts was 10 times in yield as high as the previous solvent-extracts and had relatively low contents of caffeine and tannin. From these results, it can be concluded that glycerine-water is the most suitable solvent and its extracts can be most favorably used in the products of confectionary, gum, candy, etc.

Purpose: The purpose of this paper is to analyze the trade structure and competitiveness of Korea’s informationtechnology (IT) industry in comparison to that of ASEAN, particularly in terms of quality. Research design, data, and methodology: Indices such as trade specialization index (TSI), Revealed ComparativeAdvantage (RCA), and Market Comparative Advantage (MCA) are used. Further, an Intra-industry Trade (IIT) index isused to analyze qualitative changes in horizontal intra-industry trade and Intra-industry trade of high- and low-qualitygoods. Results: An analysis of export competitiveness through RSCA analysis showed that the Korean IT industry’scompetitiveness against ASEAN is strong, and its competitiveness is gradually improving. By classification, broadcastingdevices, parts, communication devices, and information devices were found to be highly competitive. In addition, thecompetitiveness of broadcasting, parts and communication devices in 2018 compared to 2010 has been shown to bemore competitive and improved, but information devices have weakened further. According to the IIT analysis, morethan 60% of Korea and ASEAN were made up of trade in the industry, and as of 2018, the ASEAN Korean ITindustry had improved qualitative competitiveness compared to 2010. As a result of IIT analysis based on tradevolume, HIIT has decreased and VIIT has increased, indicating that trade within horizontal industries is shifting fromvertical to vertical industries. The analysis of IIT based on the number of items showed that HIIT is increasing andVIIT is decreasing, unlike the analysis of trade volume. However, as VIITL is decreasing and VIITH is increasing, thequalitative competitiveness of ASEAN Korea IT has improved. Implications: This study has academic and political implications, as it analyzes changes in Korea’s IT tradecompetitiveness. However, it is somewhat limited as factors determining qualitative aspects has not been considered.

OTT 서비스의 세 가지 질적 요소: 혼합적 연구방법을 통한 접근

유재선,박재철,전현준,손재열 한국경영정보학회 2022 Information systems review Vol.24 No.1

OTT(Over-the-top Media) 서비스는 근래 동영상 콘텐츠를 소비하는 새로운 수단이 되었다. OTT 시장이 성장하며 사업자들 간의 경쟁이 치열해졌지만, 사용자의 지속적인 OTT 서비스 구독 요인을 발굴하고 이론적 모델에 적용한 체계적 연구는 부족한 실정이다. 본 연구에서는 발달적 순차 혼합 연구 방법을 통해 질적 요인을 발굴한 후, 그것이 구독 후 경험 및 지속적 구독 의도에 미치는 영향을 본다. 질적 요인을 찾는 단계에서는 OTT 사용자의 구독 지속 의도에 중요하게 영향을 미치는 6개의 요인을 도출하였다. 이를 바탕으로 OTT의 질적 요인 3가지를 ISSM(정보시스템성공모델, Information Systems Success Model)에 적용하여 가설 및 연구 모델을 수립하였다. 연구 모델의 검증을 위해서 한국의 OTT 사용자 226명을 대상으로 서베이를 실시하였으며, 데이터는 구조방정식 모델링(SEM)을 사용하여 분석했다. 분석 결과 콘텐츠의 질이 인지된 즐거움 및 만족에 영향을 미치는 핵심 요인임을 발견했다. 서비스의 질은 인지된 즐거움에 영향을 미쳤으며, 인지된 즐거움은 지속적 사용 의도에 순차적으로 영향을 미쳤다. 시스템의 질은 만족에 직접적 영향을 미쳤다. 본 연구는 질적 연구를 통해 도출한 사용자의 경험 관련 요인을 ISSM에 응용해, OTT라는 정보시스템의 이해를 풍부하게 하는 시사점을 가진다. 이러한 시사점을 OTT 사용자의 경험 및 지속적 구독 의도 향상을 위해 사업자들이 활용할 수 있으리라 기대한다.

To find serotonin(5-hydroxytryptamine, 5-HT)-antagonizing activities in traditional herbal drugs, crude extracts from 66 kinds of traditional herbal drugs were randomly screened for inhibitory effects on 5-hydroxytryptophan(HTP)-induced diarrhea in mice. Intraperitoneal injection of 5-HTP(2.5 mg/kg) induced diarrhea in 92% of mice, when observed from 10 to 15 min after injection. Crude extracts(2 g/kg) from 66 kinds of traditional herbal drugs were orally pretreated for 1 h before 5-HTP injection. Of the 66 herbal drugs screened, Ephedrae Herba(麻黃), Cimicifugae Rhizoma(升麻), Anisi stellati Fructus(八角茴香), Aurantii Fructus(枳實), Polygalae Radix(遠志) showed the most potent inhibiting activities against 5-HTP(2.5 mg/kg)-induced diarrhea in mice. There are at least 3 possible mechanisms that would be responsible for the inhibitory effect of crude extracts on 5-HTP-induced diarrhea; 1) crude extract-induced inhibition of the activity of aromatic aminoacid decarboxylase catalyzing the conversion of 5-HTP to 5-HT, 2) crude extract-induced blockade of 5-HT receptor(s) in the gastrointestinal tract responsible for 5-HTP-induced diarrhea, 3) crude extract-induced inhibition of gastrointestinal activity, irrespective of 5-HT system. The exact mechanisms and molecules, responsible for the inhibitory effect of crude extracts on 5-HTP-induced diarrhea remain to be clarified.

자본이득세제에 관한 연구

유재선,김태정 대한경영교육학회 2009 경영교육저널 Vol.16 No.-

자본이득이 무엇인지에 대하여 한마디로 말하기는 어렵지만, 이를 자산의 보유기간 중 발생하는 경제가치의 증가분이라고 정의할 수 있다. 현실적으로 미실현 양도소득에 대한 과세는 그 사례를 찾기 어려운 만큼 부동산 자본이득에 대한 과세는 부동산의 처분시 발생하는 양도가액과 취득가액 및 필요경비의 차이, 즉 양도차익에 대한 과세라 할 것이다. 자본이득은 순자산증가설에서 주장하는 포괄적 소득개념에서 볼 때 경제력의 증가와 담세력의 향상이라는 측면에서 과세소득에 포함되어야 한다는 것이 통설이다. 공평의 차원에서 보자면 자본이득과 통상소득의 담세력은 차이가 없으므로 과세에 있어 차별을 둘 이유가 없다. 그러나 자본이득과세에 내재하는 결집효과, 동결효과, 인플레이션으로 인한 명목소득에의 과세와 같은 구조적 특징들은 통상소득과는 다른 성질을 나타내고 이에 대한 조세우대조치들을 정당화하는 근거가 되고 있다. It is not easy to explain what Captipal Gain is in a word, but A Capital Gain is a profit that results from investments into a capital asset, such as stocks, bonds or real estate, which exceeds the purchase price. A capital gain tax is a tax charged on capital gains, the profit realized on the sale of nonis, boo, basset that was purchasedbat a loal eprice. The asst common capital gain are realized from the sale of stocks, and propl st.reor indleiduexcethe asst f gnificant exemption is the family home. The sale of personal residential property is normally exempt from Capital Gain Tax.
