지난 2021년, 국내 최초로 온라인 소비가 오프라인 소비를 뛰어넘을 정도로 언택트 경제가 급부상하였다. 덕분에 언택트 시장의 주도권을 가진 라이브 커머스는 무서운 속도로 성장하고 있고, 이는 적어도 2023년까지 이어질 것으로 예상된다. 중소기업은 물론 대기업, 심지어 개인까지 라이브 커머스 시장에 탑승한 현재, 라이브 커머스 시장의 경쟁력은 점차 사라지고 있다. 이로 인해 공급자들은 차별성을 두기 위해 여전히 다양한 방법을 찾아 시도하고 있다. 본 논문에서는 계속해서 수요되는 라이브 커머스 시장에서 경쟁력을 갖출 수 있는 방법으로 LED Wall의 활용을 제안한다.

There has been emerging general agreement on the relative importance of producer services in a economy. This research describes the spatial patterns and trends in producer services at different spatial scales. The other research aim is to explain the impacts of producer services on spatial changes at the national level and at the intra-metropolitan level in Seoul. Producer services have highly concentrated in metropolises, especially Seoul. Between 1986 to 2001, an important spatial change in the producer services at the national level has been their growth in the Capital Region, reinforcing the role and function of Seoul. This reinforced role of Seoul is closely related to its competitive advantages arising from economies of urban. There have been some dramatic changes in the location of producer services within Seoul. The most important change was the growth of the Youngdong area, previously a sub-center for businesses, as the most important location for producer services, exceeding the previous dominant role of the CBD area. The changing urban form of Seoul is partly related to the onset of some diseconomies of urbanization in the CBD, while at the same time Youngdong has reached a stage at which it is benefiting from the agglomeration of a variety of firms, in addition to a favourable social and physical infrastructure.

Graham Greene's The Quiet American is a war novel set in Vietnam. Thus, although war-related political stories are mainly unfolded, this novel presumes that Westerners are basically superior to the colored Vietnamese. In addition to racial issues, it describes the dual discrimination and inequality that women face. Phung, a Vietnamese woman who wishes to live a rich and comfortable life through marriage to a Western man, is a gender underdog oppressed by the capital and males. She is discriminated against by selfish views created by men, such as being expressed as an ignorant woman who can feel physical pain but not mental pain and being described as a partner to satisfy men's pleasure. Fowler and Pyle, the male lead characters who are gender strong, treat the Asian woman as a low-status person who is qualitatively different from Westerner and use and exploit the woman simply to satisfy their selfish needs. Therefore, it is hard to say that this story involves true love, as it is based on an unequal relationship. Eventually, Pyle's death brings Phung back to Fowler, confirming that Asian women are unable to escape from the gender underdog of Western men.

In order to examine differential mortality, the life tables for the insured persons in national pension scheme were estimated by sex and types of coverage(the insured in workplaces vs. the insured in rural areas). The averages of 1994-1996 data are used for insured in workplaces, but 1996 data are used for insured in rural areas. Life expectancies at the age of 18 are 59.5 years and 67.2 years each for insured males and females and thus 7.7 years longer for females than males in workplaces. Sex difference in mortality reduces as age increases, and more rapidly at younger ages than old ages. For insured in rural areas, life expectancies at the age of 18 are 51.4 years and 61.1 years each for insured males and females and thus sex difference is 9.7 years. The greater sex difference in mortality in rural areas can be explained by sex selective migration. The difference of life expectancy between insured in workplaces and insured in rural areas is 8.1 years for males, and 6.1 years for females. Because rural-urban difference in educational attainment is greater for males than females, the greater difference in life expectancy is observed for males than females.

The informativeness of accounting earnings to investors may be used as a measure of the quality of accounting information. The ownership structure is considered to be related to both of two variables, the reliability of earnings reflecting the economic performance of the enterprise and the existence of alternative information sources. Earnings manipulation may mitigate the correlation between accounting earnings and the economic performance and alternative information sources decrease the value of accounting earnings as an information. Thus ownership structure could influence the informativeness of accounting earnings. This paper classifies ownership into three categories, management or inside ownership, institutional investors and large outside blockholders, and diffuse outside ownership and examines theoretically the difference of information effectiveness under each ownership structure. The earnings manipulation hypothesis supports the assertion that the separation of ownership from control motivates earnings manipulation. And differential information hypothesis suggests that more non-accounting information of firms with institutional or concentrated outside ownership is provided. Outside blockholders have alternative information sources that make accounting manipulation ineffective. While most previous studies have examined the effect of ownership on the informativeness of earnings from earnings manipulation hypothesis, this study is motivated by both earnings manipulation hypothesis and differential information hypothesis.

Decision trees are mainly used for the classification and prediction in data mining. The distribution of spatial data and relationships with their neighborhoods are very important when conducting classification for spatial data mining in the real world. Spatial decision trees in previous works have been designed for reflecting spatial data characteristic by rating Euclidean distance. But it only explains the distance of objects in spatial dimension so that it is hard to represent the distribution of spatial data and their relationships. This paper proposes a decision tree based on spatial entropy that represents the distribution of spatial data with the dispersion and dissimilarity. The dispersion presents the distribution of spatial objects within the belonged class. And dissimilarity indicates the distribution and its relationship with other classes. The rate of dispersion by dissimilarity presents that how related spatial distribution and classified data with non-spatial attributes we. Our experiment evaluates accuracy and building time of a decision tree as compared to previous methods. We achieve an improvement in performance by about 18%, 11%, respectively.

The purpose of this study was to examine the effects of altruism and the civil right consciousness on the ageism against older people. Using data of 1,513 persons over 18 years old from the Korean General Social Survey(KGSS)(2011), this study applied descriptive analyses, t-test, ANOVA, correlation analysis and multi-regression with STATA14. According to results, the degree of ageism was slightly lower(2.43 out of 5). Compared to age groups, the results were followed: elderly, middle age, and young age group. Among them, the ageism level of the group to have experiences of discrimination was higher than one of the group not to have it. The degree of altruism was high(3.95 out of 5), followed by elderly, middle age, and young age group. The group experienced in discrimination had higher level of altruism than another. The degree of the civil right consciousness was high(5.83 out of 7) without differences among age groups. In the results of regression analysis, the ageism was negatively affected by altruism and the civil right consciousness. Based on the results, this study suggested practical and political opinions for reducing ageism.

Prior research has investigated different effects of brand performance information such as premium price information and market share information on brand equity components - quality perception and brand preference. It was shown that the differential effects of brand performance information could depend on product-related variables like product category concept and quality variation in the product category. In this study, we conducted an experiment to find out how personal characteristics such as self-construal, price perception and brand commitment could influence the effects of different types of brand performance information. The results show that individuals who have independent self-construal, favorable price perception and emotional commitment with the brand develop more favorable evaluation of the premium price performance information resulting in more positive evaluations of the brand. However, individuals who have interdependent self-construal, unfavorable price perception and cognitive commitment with the brand develop more favorable evaluation of the market share performance information resulting in more positive evaluations of the brand. We discuss the theoretical and practical implications of this study and its limitations, along with future research interests.

본 실험에서는 Silicon (001) 기판을 사용하여 silicon 기판상에 modified Stranski-Krastanow(S-K) 방식으로 InAs quantum dot (QD) 을 성장하고 그 위에 InSb layer를 형성하였다. 기판온도 $390^{\circ}$에서 In injection period를 4번 반복하여 제작된 InAs quantum dot layer를 buffer로 사용하였으며, QD layer의 밀도는 $1{\mu}m^2$ 당 600개, height가 $6.2\;{\pm}\;2.0\;nm$, width가 $36.1\;{\pm}\;9.2\;nm$ 정도이다. 성장된 $2.8{\mu}m$ 두께의 InSb film의 특성을 분석해 보면 AFM 상에서의 root mean square (rms) roughness는 5.142nm정도이며, electron mobility는 340 K 에서 $41,352cm^2/Vs$, 1.8 K에서는 $4,215cm^2/Vs$ 정도를 나타내었다. 본 실험에서는 다른 실험과는 달리 InAs QD 을 buffer layer로 사용하였으며, silicon기판도 아무런 처리가 되지 않은 (001)기판을 사용하였으므로 기존의 다른 연구 결과와는 차별성을 가진다. 또한 buffer로 사용된 InAs quantum dot layer의 종류를 한 가지로 고정하고 실험을 하였지만 추후 더욱 다양한 밀도와 크기의 quantum dot layer를 적용시키고, 기존의 다른 논문에서 적용된 방법들을 추가로 적용시켜 본다면 mobility값은 더욱 증가할 것으로 생각된다. 이러한 연구를 통해 값이 싸고 구하기 쉬운 silicon기판상에 silicon에 비하여 더 좋은 특성을 갖는 III-V족 화합물 반도체 소자를 구현 할 수 있을 것으로 생각된다.
