본 연구는 글로벌 전자책 플랫폼의 부상 과정과 유형을 구글, 아마존, 애플에 대한 사례연구방법(case study method)으로 분석하였다. 글로벌 전자책 플랫폼들은 급격히 변화되는 디지털 기술 환경과 각자의 주어진 적합도 지형(fitness landscape)에 적응하는 과정을 뚜렷이 보여주고 있다. 적응과 진화 과정에서 결정적인 요인이 된 것은 고유한 선택 범주(distinct selection criteria), 자원 풍요도(degree of resource abundance), 개방적 혁신에 기반한 탐색 과정(search process)이다. 이 요인들을 기반으로 글로벌 전자책 플랫폼들은 종분화(種分化, speciation) 과정에서 니치(niche)를 창출하였으며, 초기 조건(initial condition)인 핵심 자원(key resource)에 따라 경로 의존적으로 진화하였다. 각각의 전자책 플랫폼들은 오픈 플랫폼(open platform)과 하이브리드 플랫폼(hybrid platform), 그리고 클로우즈드 플랫폼(closed platform)으로 진화하였다. 구글 이북(eBook)은 안드로이드 기반의 다양한 단말기를 통해 주체들이 직접 운영하며 참여하는 개방성과 확장성을 특징으로 하며, 아마존 킨들(Kindle)은 온라인 대형 서점에서 확장되어 단말기와 유무선 모바일 네트워크까지 아우르며 개방성과 폐쇄성을 동시에 지닌 플랫폼으로 성장하고 있다. 또한 아이북스 스토어(iBooks Store)는 아이폰과 아이패드 등 하드웨어 경쟁력과 폐쇄성 기반의 에이전시 모형으로 진화하고 있다.

지난 십년동안 인터넷을 통한 전자상거래는 빠른 속도로 성장해 왔다. 이러한 인터넷의 발달은 기업들의 사업방식에 많은 변화를 유도했으며, 그 중에서도 마케팅경로의 구조와 경로 구성원들 사이의 관계에 중요한 변화를 초래하고 있다. 각 기업이 처한 시장환경은 다양하며 이 다양한 시장 환경은 인터넷 경로가 각 시장에 미치는 효과를 조절하는 역할을 한다. 이러한 시장의 다양성에도 불구하고 지금까지의 선행연구들은 각기 특정한 하나의 시장상황(unique setting)을 상정하여 인터넷경로 도입이 그 시장에 미치는 영향을 분석하는데 그쳐왔다. 이러한 기존 연구의 공백을 채우기 위해 본 연구는 시장의 다양성을 소비자의 지리적 분포, 시장의 인터넷 수용도의 측면에서 살펴보고 이러한 시장 환경이 인터넷 경로 도입 효과에 미치는 영향에 관하여 조사해 보고자 한다. 이를 위해 본 연구는 다양한 소비자들의 지리적 분포, 경쟁강도, 소비자의 인터넷 상거래에 대한 수용도 등을 포함한 다양한 시장 환경을 수요모형에 반영시켜 그 영향력 분석을 가능하도록 하였다. 그러나, 다양한 시장 요소를 모형에 반영하는 과정에서 수요모형이 복잡한 구조를 가지게 되었다. 이 문제를 극복하고 게임이론의 균형해를 도출하기 위해 Newton-Raphson algorithm을 사용한 numerical search 방법을 사용하였다. 분석결과 두 종류의 경로에 대한 소비자선호의 분포에 따라 생산자의 가격차별정도, 생산자와 독립소매상 간의 경로이윤 배분율, 그리고 인터넷경로 도입이 각 경로주체의 이윤 향상에 도움이 되는지의 여부, 소비자잉여 등이 달라질 수 있음을 발견하였다. 끝으로 연구의 학술적, 실무적 시사점과 한계점 및 향후 연구방향도 논의되었다.

Price rigidity involves prices that do not change with the regularity predicted by standard economic theory. It is of long-standing interest for firms, industries and the economy as a whole. However, due to the difficulty of measuring price rigidity and price adjustments directly, only a few studies have attempted to provide empirical evidence for explanatory theories from Economics and Marketing. This paper proposes and validates a research model to examine different theories of price rigidity and to predict what variables can explain the observed empirical regularities and variations in price adjustment patterns of Internet-based retailers. I specify and test a model using more than 3 million daily observations on 385 books, 118 DVDs and 154 CDs, sold by 22 Internet-based retailers that were collected over a 676-day period from March 2003 to February 2005. I obtained a number of interesting findings from the estimation of our logit model. First, quality seems to play a role-I find that both price levels as proxies for store quality, and information on the quality of a product consumers have, affect online price rigidity. Second, greater competition(i.e., less industry concentration) leads to less price rigidity(i.e., more price changes) on the Internet. I also find that Internet-based sellers more frequently change the prices of popular products, and the sellers with broader product coverage change prices less frequently, which seem due to economic forces faced by these Internet-based sellers. To the best of my knowledge, this research is the first to empirically assess price rigidity patterns for multiple industries in Internet-based retailing, and attempt to explain the variation in these patterns. I found that price changes are more likely to be driven by quality, competitive and economic considerations. These results speak to both the IS and economics literatures. To the IS literature these results suggest we take economic considerations into account in more sophisticated ways. The existence and variation in price rigidity argue that simplistic assumptions about frictionless and completely flexible digital prices do not capture the richness of pricing behavior on the Internet. The quality, competitive and economic forces identified in this model suggest promising directions for future theoretical and empirical work on their role in these technologically changing markets. To the economics literature these results offer new evidence on the sources of price rigidity, which can then be incorporated into the development of models of pricing at the firm, industry and even macro-economic level of analysis. It also suggests that there is much to be learned through interdisciplinary research between the IS, economics and related business disciplines.

교육과정은 학교의 정체성을 표현할 수 있는 가장 중요한 수단으로, 특히 대학은 자율적인 교육과정 편성과 운영이라는 권한을 가지고 있다. 따라서 새로운 지식기반사회의 가치 창출 원천이 되는 지식을 생성, 축척, 전달하는 능력을 교육하는 정보소양 교육과정은 대학의 교양교육에서 중요한 비중을 차지한다. 이에 본 연구는 교육과정을 설계 운영 평가할 때 참조할 수 있는 3차원 큐빅 참조 모델을 제안하였다. 이를 위해 국내외 몇 개 대학의 교양교육을 조사하였고, 학생 설문을 통해 정보소양 교육의 만족도 및 앞으로의 방향을 설문하였다. 이를 통해 설계된 참조 모델을 이용하여 정보소양 강좌의 교육과정을 설계하였고, 한 학기동안 운영해 본 결과 수강생들이 높은 만족도를 보였다. 본 모델은 체계적이고 융통성있는 적용이 가능하기 때문에 각 대학의 정보소양 교육과정을 설계 운영 평가하는데 좋은 참조 모델이 될 것이다.

The outline and characteristics of the important doctors of the 'Zhe Zhong Pai'(折衷派) are as follows. Part 1. In the late Edo(江戶) period The 'Zhe Zhong Pai', which tried to take the theory and clinical treatment of the 'Hou Shi Pai (後世派)' and the 'Gu Fang Pai(古方派)' and get their strong points to make treatments perfect, appeared. Their point was 'The main part is the art of the ancients, The latter prescriptions are to be used'(以古法爲主, 後世方爲用) and the "Shang Han Lun(傷寒論)" was revered for its treatments but in actual use it was not kept at that. As mentioned above The 'Zhe Zhong Pai' viewed treatments as the base, which was the view of most doctors in the Edo period. However, the reason the 'Zhe Zhong Pai' is not valued as much as the 'Gu Fang Pai' by medical history books in Japan is because the 'Zhe Zhong Pai' does not have the substantiation or uniqueness of the 'Gu Fang Pai', and also because the view of 'gather as well as store up'(兼收並蓄) was the same as the 'Kao Zheng Pai'. Moreover, the 'compromise'(折衷) point of view was from taking in both Chinese and western medical knowledge systems(漢蘭折衷). Generally the pioneer of the 'Zhe Zhong Pai' is seen as Mochizuki Rokumon(望月鹿門) and after that was Fukui Futei(福井楓亭), Wadato Kaku(和田東郭), Yamada Seichin(山田正珍) and Taki Motohiro(多紀元簡). Part 2. The lives of Wada Tokaku(和田東郭), Nakagame Kinkei(中神琴溪), Nei Teng Xi Zhe(內藤希哲), the important doctors of the 'Zhe Zhong Pai', are as follows. First Wada Tokaku(和田東郭, 1743-1803) was born when the 'Hou Shi Pai' was already declining and the 'Gu Fang Pai' was flourishing and learned medicine from a 'Hou Shi Pai' doctor, Hu Tian Xu Shan(戶田旭山) and a 'Gu Fang Pai' doctor, Yoshimasu Todo(吉益東洞). He was not hindered by 'the old ways(古方)' and did not lean towards 'the new ways(後世方)' and formed a way of compromise that 'looked at hardness and softness as the same'(剛柔相摩) by setting 'the cure of the disease' as the base, and said that to cure diseases 'the old way' must be used, but 'the new way' was necessary to supplement its shortcomings. His works include "Dao Shui Suo Yan(導水瑣言)", "Jiao Chiang Fang Yi Je(蕉窗方意解)" and "Yi Xue Sho(醫學說)". Second. Nakagame Kinkei(中神琴溪, 1744-1833) was famous for leaving Yoshimasu Todo(吉益東洞) and changing to the 'Zhe Zhong Pai', and in his early years used qing fen(輕粉) to cure geisha(妓女) of syphilis. His argument was "the "Shang Han Lun" must be revered but needs to be adapted", "Zhong Jing can be made into a follower but I cannot become his follower", "the later medical texts such as "Ru Men Shi Qin(儒門事親)" should only be used for its prescriptions and not its theories". His works include "Shang Han Lun Yue Yan(傷寒論約言)". Third, Nei Teng Xi Zhe(內藤希哲, 1701-1735) learned medicine from Qing Shui Xian Sheng(淸水先生) and went out to Edo. In his book "Yi Jing Jie Huo Lun(醫經解惑論)" he tells of how he went from 'learning'(學) to 'skepticism'(惑) and how skepticism made him learn in 'the six skepticisms'(六惑). In the latter years Xi Zhe(希哲) combines the "Shen Nong Ben Cao Jing(神農本草經)", the main text for herbal medicine, "Ming Tang Jing(明堂經)" of accupuncture, basic theory texts "Huang Dui Nei Jing(皇帝內經)" and "Nan Jing(難經)" with the "Shang Han Za Bing Lun", a book that the 'Gu Fang Pai' saw as opposing to the rest, and became 'an expert of five scriptures'(五經一貫). Part 3. Asada Showhaku(淺田宗伯, 1815-1894) started medicine at Zhong Cun Zhong Zong(中村中倧) and learned 'the old way'(古方) from Yoshimasu Todo and got experience through Ouan Yue(川越) and Fu Jing(福井) and received teachings in texts, history and Wang Yangmin's principles(陽明學) fmm famous teachers. Showhaku(倧伯) meets a medical official of the makufu(幕府), Ben Kang Zong Yuan(本康宗圓), and receives help from the 3 great doctors of the Edo period, Taki Motokato(多紀元堅), Xiao Dao Xue Gu(小島學古) and Xi Duo Cun Kao(喜多村栲窻) and further develops his arts. At 47 he diagnoses the general Jia Mao(家茂) with 'heart failure from beriberi'(脚氣衡心) and becomes a Zheng Shi(徵土), at 51 he cures a minister from France and received a present from Napoleon, at 65 he becomes the court physician and saves Ming Gong(明宮) Jia Ren Qn Wang(嘉仁親王, later the 大正天皇) from bodily convulsions and becomes 'the vassal of merit who saved the national polity(國體)' At the 7th year of the Meiji(明治) he becomes the 2nd owner of Wen Zhi She(溫知社) and takes part in the 'kampo continuation movement'. In his latter years he saw 14000 patients a year, so we can estimate the qualjty and quantity of his clinical skills. Showhaku(宗伯) wrote over 80 books including the "Ju Chuang Shu Ying(橘窻書影)", "Wu Wu Yao Shi Fang Han(勿誤藥室方函)", "Shang Han Biang Shu(傷寒辨術)", "Jing Qi Shen Lun(精氣神論)", "Hunag Guo Ming Yi Chuan(皇國名醫傳)" and the "Xian Jhe Yi Hua(先哲醫話)". Especially in the "Ju Chuang Shu Ying(橘窻書影) he says "the old theories are the main, and the new prescriptions are to be used"(以古法爲主, 後世方爲用), stating the 'Zhe Zhong Pai' way of thinking, In the first volume of "Shang Han Biang Shu(傷寒辨術)" and "Za Bing Lun Shi(雜病論識)", 'Zong Ping'(總評), He discerns the parts that are not Zhang Zhong Jing's writings and emphasizes his theories and practical uses.
