2000년대 초반 뉴미디어 플랫폼을 통해 등장한 '먹방'은, 사회경제적 조건의 악화 속에서 혼자 식사를 해야 하는 청년 세대의 삶을 반영하였다. 많은 젊은이들이 먹방을 함께 시청하며, 비슷하게 어려운 처지를 겪는 이들과 가상적 일상 생활의 공동체를 구축하며 위안을 얻을 수 있었다. 이후 먹방은 사회를 반영하며, 또한 시청자의 요구를 수용하며 다양한 형태로 진화하여, 현재는 한국에서만이 아니라 글로벌 현상이 되었다. 기존 연구는 이런 먹방의 성장과 변화보다는 초반에 나타나는 화제거리로서의 현상에만 주목하여 먹방을 제한적으로 다루고 있다. 본 논문은 이런 한계를 비판적으로 검토하며, 먹방의 성장과 발전이 사회적 변화 과정과 어떻게 상호작용하며 전개되었는가, 그리고 이런 먹방의 고유성이 어떻게 뉴 미디어의 특성 속에서 등장할 수 있었는 가를 살펴보고자 한다. 이를 통해 먹방이 세계적 현상으로 성장한 맥락과 기존 미디어에 미친 영향 등을 두루 살펴볼 수 있을 것이다.

Mercury (Hg) is ubiquitous throughout the earth's atmosphere. The uniqueness of its atmospheric geochemistry is well-known with the high environmental mobility and relatively long atmospheric residence time (c.a., 1 year) associated with its high chemical stability. Despite a growing recognition of the environmental significance of its global cycling, the prexisting Korean database for atmospheric Hg is extremely rare and confined to a number of concentration measurements conducted under relatively polluted urban atmospheric environments. To help activate the research on this suvject, an in-depth analysis on the current development in the measurements of atmospheric mercury and the associated fluxes has been made using the most using the most updated data ests reported worldwide. As a first step toward this purpose, the most reliable techniques commonly employed in the measurements of its concentration in the background atmosphere are introduced in combination with the flux measurement techniques over soil surface such as: dynamic enclosure (or field flux chamber) method and field micrometeorological method. Then the results derived using these measurement techniques are discussed and interpreted with an emphasis on its mobilization across the terrestrial biosphere and atmosphere interface. A unmber of factors including air/soil temperature, soil chemical composition, soil water content, and barometric pressure are found out to be influential to the rate and amount of such exchange processes. Although absolute magnitude of such exchange processes is insignificant relative to that of the major component like the oceanic environment, this exchange process is thought to be the the predominant natural pathway for both the mobilization and redistribution of atmospheric Hg on a local or regional scale.

Over the last decade, some Korean enterprises have emerged to become global players in their specialized products. How have they achieved such tremendous technological progress in a short period of time? This paper explores that question by examining the characteristics of technological innovation activities at major Korean enterprises. The paper begins with a brief review of the stages of economic growth and science and technology development in Korea. Then, the existing literature, explaining the Korean innovation model, is analyzed in order to establish a new framework for the Korean innovation model. Specifically, Korean firms have experienced three sequential phases, and thus, the Korean model, at the firm level, can be coined as "path-following," "path-revealing," and "path-creating." Then, the stylized facts in the first phase (path-following) and the second phase (path-revealing) are discussed, in the context of empirical evidence from the areas of memory chips, automobiles, shipbuilding, and steel. In terms of technology development, the Korean model has evolved as "collective learning" in the first phase, "collective recombination" of existing knowledge and technology in the second phase, and is assumed as "collective creativity" in the third phase. Ultimately, all three can be classified as "collective creation". Korean firms now face a transition in the modes of technological innovation in order to efficiently implement the third phase. To achieve remarkable progress again, as they did in the past, and to sustain the growth momentum, Korean firms should challenge new dimensions such as creative technological ideas, distinctive technological capabilities, and unique innovation systems -- all of which connote 'uniqueness'. Finally, some lessons from the Korean technological innovation experience are addressed.

The shape and the distribution of material construction of the scatterer may be obtained from its scattered fields by the iterative inversion in the spectral domain. The illposedness, the resolution, and the uniqueness of the inversion are the key problems in the inversion and inter-related. The illposedness is shown to be caused by the evanescent modes which carries and amplifies exponentially the measurement errors in the back-propagation of the measured scattered fields. By filtering out all the evanescent modes in the cost functional defined as the squared difference between the measured and the calculated spatial spectrum of the scattered fields from the iteratively chosen medium parameters of the scatterer, one may regularize the illposedness of the inversion in the expense of the resolution. There exist many local minima of the cost functional for the inversion of the large and the high-contrast scatterer and the hybrid algorithm combining the genetic algorithm and the Levenberg-Marquardt algorithm is shown to find efficiently its global minimum. The resolution of reconstruction obtained by keeping all the propating modes and filtering out the evanescent modes for the regularization becomes 0.5 wavelength. The super resolution may be obtained by keeping the evanescent modes when the measurement error and instance, respectively, are small and near.

사회적, 문화적 배경이 유사한 한국과 일본에서 선호하는 유튜브 콘텐츠의 특징과 성향에 대한 기초 데이터를 제공하며, 인기 콘텐츠 제작을 위한 힌트를 얻고자 양국의 인기 상위 250개의 유튜브 채널 콘텐츠를 조사, 분류하고 사회통계학적 접근 방법을 활용하여 유튜브 채널 운영 주체의 유형, 콘텐츠 채널의 분야별 분포, 한일 양국의 개인 유튜브 가입경과일과의 연관성에 대해 알아보았다. 그 결과, 한국은 방송사와 연예 기획사 등이 K-pop, 드라마, 예능 등의 한류 콘텐츠의 확산을 위한 글로벌 마케팅을 목적으로 한 홍보 영상을 제작, 채널 개설, 운영하는데 반해, 일본은 도구나 물건, 행동과 관련된 실험, 토크쇼, 일상 등을 소재로 하는 개인 유튜브 채널의 운영이 많고 분야별 다양성 및 독창성이 인정된다. 이는 일본 개인 크리에이터들이 이른 시기부터 니코니코동화(ニコニコ動画)와 같은 콘텐츠 운영 활동을 통해 콘텐츠의 독창성과 다양성을 기르기 위한 시간 확보가 가능했기 때문이다. 향후, 유튜브 영향력의 증대를 고려하여 개인 크리에이터들은 콘텐츠 소비자의 특성을 파악하여 감정적, 지식적, 경제적 가치에 기반한 다양한 시도를 해야 하며, 사회적으로는 1인 미디어 제작과 운영의 활성화를 위한 교육과 홍보 그리고 경제적 지원책이 필요하다.

Purpose - This research aims to investigate the factors that influence consumer's overseas online shopping behavior. Consumers adopt overseas online shopping as a new buying way and more and more consumers prefer overseas online shopping than traditional shopping ways. Consumers' behaviors in this shopping experience can be different from other shopping experiences. With the increase of overseas online shopping, we need to find antecedents and results of overseas online shopping. Especially there would be positive or negative factors which influence overseas online shopping motivation. To find the relationship, this study examines self-efficacy and impulsivity as major factors which influence overseas online shopping. We also suggest that several attitude factors increase self-efficacy and it is positively related to customer satisfaction. On the other hand, we assume that overseas online shopping factors influence impulsivity of buying and it will decrease customer satisfaction. Research design, data, and methodology - This empirical study data were collected from Korean people who experience overseas online shopping. The subjects for this study were confined to shoppers who used overseas online shopping within the past six months. A total of 267 responses were gathered. SPSS 23.0, PLS 2.0 software were used in the data analysis. Descriptive statistics were used to show sample characteristics. We examined reliability, validity test for constructs. All measurement items used seven-point scales(1= very strong disagree, 7 = very strongly agree) drawn from previously published papers. Partial Least Square method was applied to find the relationship between antecedent factors and dependent factors and hypotheses were estimated. Results - Results show that perceived superiority, perceived ease of use, perceived transaction safety, perceived behavioral control positively affect self-efficacy. Self-efficacy influences positively to consumer's post purchase satisfaction. Perceived monetary benefit and perceived uniqueness motivated impulse buying. This can make consumer's post purchase dissatisfaction. Conclusions - This paper attempted to confirm the existence of both the positive and negative faces of overseas online shopping. The result reveals that self-efficacy is a major factor which may increase satisfaction in the overseas online shopping. Usually, we can think monetary benefit and uniqueness of products motivate overseas online shopping. But it can also intrigue impulse buying and negatively affect customer relationship. Therefore companies should provide enough products information to their potential customers and they might apply adequate processes such as recommendation, comparing systems to build long term relationship with their customers.

To satisfy consumers' desire to enjoy their own individuality and cultural trends, the discovery of various materials and the expression of materials embodying their characteristics are increasingly important in the fashion jewelry industry. This study examines, paper mulberry fiber, a raw material of hanji that has been excavated as a new material for fashion jewelry, is durable as wall as, soft and easy to form, has a unique texture along with, excellent aesthetic quality, and expresses various colors, thereby differentiating itself from traditional fashion jewelry materials. The material itself also has symbolic significance as an approach to discovering new sustainable materials for fashion jewelry to ensure increased specificity of the product based on the premise of freedom of expression. The weight and optimal drying time of chicken fiber were derived for the study of fashion jewelry expression using the characteristics of paper mulberry fiber. The techniques of casting, deflection, packing and winding (winding beads with fibers and straps) were derived and four brooches were produced in total. This study is meaningful for the future of, the fashion jewelry industry as it presents the uses of new materials such as paper mulberry fiber to induce multidisciplinary consumption and to suggest a direction for the creation of new value-added products. Further, in order to expand the realm of fashion jewelry industry with our own competitive products that have secured our cultural identity and uniqueness in the global market, there must be continued follow-up research on mass production methods for industrialization.

We have performed systematic studies of the properties of dust in various environments of nearby galaxies with AKARI. The unique capabilities of AKARI, such as near-infrared (near-IR) spectroscopy combined with all-sky coverage in the mid- and far-IR, enable us to study processing of dust, particularly carbonaceous grains includings polycyclic aromatic hydrocarbons (PAHs), for unbiased samples of nearby galaxies. In this paper, we first review our recent results on individual galaxies, highlighting the uniqueness of AKARI data for studies of nearby galaxies. Then we present results of our systematic studies on nearby starburst and early-type galaxies. From the former study based on the near-IR spectroscopy and mid-IR all-sky survey data, we find that the properties of PAHs change systematically from IR galaxies to ultraluminous IR galaxies, depending on the IR luminosity of a galaxy or galaxy population. From the latter study based on the mid- and far-IR all-sky survey data, we find that there is a global correlation between the amounts of dust and old stars in early-type galaxies, giving an observational constraint on the origin of the dust.
