창업자의 기업가적 의지에 의한 기회 포착 및 기회 실현: 넷마블 게임사에 관한 사례 연구

정지용,권상집 한국기업경영학회 2016 기업경영연구 Vol.23 No.4

The purpose of this study is to examine the determinants of opportunity recognition and realization of Netmarble Games Corporation, a leading company in Korean mobile game industry. The founder of Netmarble Games has discovered new business opportunities and realized them successfully. This study focuses on entrepreneurial intent and explores how it affects the process of opportunity recognition and realization. Entrepreneurial intent is the entrepreneurial motivation that enables the potential value of a new business opportunity to be realized by driving the entrepreneur to build the capability and to fill the gap on the way to the growth. The concept of entrepreneurial intent incorporates ‘directivity’ toward new business opportunities and ‘drive’ to achieve them. Therefore, entrepreneurial intent explicates entrepreneurs’ behaviors to innovate existing businesses or to create new businesses. This study found that alert entrepreneurial intent has positive influences on opportunity recognition, realization, and business transformation. More specifically, the founder of Netmarble Games always paid sharp attention to market changes and unmet desires of customers, so that he could identify new business opportunities and concentrated full capabilities to fulfill them. At first, Netmarble started as a game portal site and succeeded in rapidly increasing the number of users with interschool game matches. Huge success in the early phase did not stop the founder from seeking new business opportunities. He expanded the business to online game publishing for stable creation of profit. Then he decided to merge Netmarble with the CJ group, a conglomerate participating in entertainment industries, to establish systematic operations and to overcome the problem of limited access to resources. Netmarble continued to grow at high double digit rates until, at some point, the sales growth started to slow down. The founder identified a new business opportunity in the new stream of technological development: mobile electronic devices and applications. He took the risk of downsizing the profitable publishing business while fostering the mobile game business. Netmarble launched new mobile games prior to competitors, so it could dominate the market in advance. Having successfully transformed the major business, Netmarble has maintained the market leadership in the mobile game industry. Netmarble did not settle for the status quo. For global expansion, it saparated from the CJ group after receiving investment funds from Tencent, the largest online service platform company in China. The founder of Netmarble constantly sought, recognized, and realized new business opportunities, which brought agility and rapid growth to the company. Such opportunities may not have been identified without entrepreneurial intent of the founder who always contemplates value creation for customers. His entrepreneurial intent set up the directivity of the businesses and activated the drive to carry them forward. This study contributes to expanding our knowledge of Korean mobile game business and the roles and effects of entrepreneurial intent. Entrepreneurial intent is especially important in making timely and innovative decisions for realizing new business opportunities. Also, rapid implementation and internalization of capabilities are essential for success. 본 연구는 국내 모바일 게임의 선두주자인 넷마블의 기회 포착 및 기회 실현 과정의 결정 요인을 분석하는 데 목적을 두고 있다. 넷마블은 게임 산업의 환경 변화 속에서 지속적으로 새로운 사업 기회를 발견하고 이를 성공적으로 실현해 왔다. 이에 본 연구는 넷마블의 창업 및 성장과정에서 창업자의 기업가적 의지에 주목하여, 기업가적 의지가 어떻게 기회 포착 및 실현을 추동했는지 분석하였다. 기업가적 의지는 성과를 달성하기 위해 필요한 자원을 확보하고 관련 역량을 구축하여 신규 사업 기회가 지닌 잠재적 가치를 실현하려는 기업가의 동기를 의미한다. 본 사례연구를 통해 기회의 포착과 실현, 그리고 그로 인한 사업 변화에서 창업자의 기업가적 의지가 핵심적인 역할을 한다는 것을 확인하였다. 넷마블은 특히 창업자의 기민한 기업가적 의지를 토대로 시장의 변화와 고객의 니즈에 초점을 맞추어 새로운 기회를 포착하였으며, 이를 성과로 만들어내기 위해 기업의 모든 역량을 새로운 기회에 집중하였다. 그 결과 퍼블리싱 사업에의 진출, 대기업과의 합병, 모바일 분야로의 전환을 성공적으로 추진할 수 있었고, 이를 통해 경쟁 기업들보다 더 빠른 성장을 거듭할 수 있었다. 본 사례연구는 국내 게임 기업의 전략에 대한 연구 영역을 모바일 게임으로 확대하고, 기업가적 의지의 역할 및 효과를 보다 깊이 있게 이해하는 데 기여하였다.

Tahar Ben Jelloun, écrivain marocain, s'intéresse, dès qu'il s'installa en France en 1973, aux problèmes de la diaspora. Il a soutenu une thèse intitulée « Problèmes affectifs et sexuels de travailleurs nord-africains en France », puis publié un essai, La plus haute des solitudes(1977), et un roman, La réclusion solitaire(1976). Quinze ans après, avec Les Yeux baissés(1991), il revient au problème de diaspora. Et récemment, il a abordé encore une fois au problème de l'immigration de la jeunesse marocaine dans Partir(2006). En tant qu'écrivain de migration, la question de diaspora est au cœur de son écriture. Ces romans, publiés avec l'intervalle de quinze ans, témoignent du changement de la situation économique et sociale entre les deux rives de la Méditerranée, de l'immigration de travail dans les années 1970 à la patera à la fin du siècle. Le travailleur de La réclusion solitaire, qui s'est immigré avant le choc pétrolier, mène une vie nue imposée par le système économique basé sur le Fordisme, alors que Fathma, qui est venue en France avec son père via le regroupement familial, vit le conflit entre deux cultures et accepte une double appartenance, ou plutôt une identité transculturelle au sein du pays qui mène une politique d'intégration. Les problèmes de « glocalisation » aggravés après la fermeture de l'espace Schengen amènent Tahar Ben Jelloun à revenir encore une fois à la question de diaspora maghrébine, surtout des jeunes marocaines, qui désirent quitter leur pays à tout prix, et qui serons condamnés à une vie marginalisée dans leur pays d'arrivée. Ces trois romans sont d'une certaine manière une réponse romanesque à l'égard de la situation donnée. Selon l’époque, Tahar Ben Jelloun choisit les différents type de personnages (travailleur immigrés, jeune fille issue de l'immigration, jeune chômeur diplômé), les différents lieux (habitat collectif, école, port), et surtout adopte les différents modèles de narration (monologue intérieur, dialogue pédagogique, fragmentation des voix) pour que les romans correspondent à la situation de diaspora dont il est né.

혈액투석 환자에게서 발생한 재생불량성 빈혈 1예

Aplastic anemia is a disease characterized by pancytopenia in the peripheral blood and hypocellular bone marrow with the fatty infiltration. The causes of the acquired aplastic anemia were usually related to drugs and immune-related diseases. A 34-years old man was admitted due to general weakness. He has been going hemodialysis for 2 years because of end stage renal disease (ESRD) due to chronic glomerulonephritis. At admission, laboratory tests showed hemoglobin 6.2 g/dL, hematocrit 18.0 %, WBC 5,710mm (neutrophil 71.8%, lymphocyte 19.1%, monocyte 5.9%), reticulocyte 1.9%, platelet 93,000/mm, Fe 12.8 ug/dL, TIBC 204 ug/dL, ferritin 941.47 ng /ml, haptoglobin 0.72 g/L, vitamin B12 508.17 pmol/L, folate 24 ng/mL, total protein 6.54 g/dL, albumin 3.76 g/dL, Alk. pohsphatase 79 IU/L, AST 30.0 IU/L, ALT 39.7 IU/L, total bilirubin 0.57 mg/dl, BUN 79.4 mg/dl and creatinine 10.18 mg/dl. Peripheral blood smear showed the normocytic normochromic anemia with anisocytosis. Anemia was diagnosed but it was irresponsive to the recombinant human erythropoietin (EPO) and blood transfusion. In the bone marrow aspiration smear were there the hypoplastic myeloid and erythroid precursors. The bone marrow biopsy section showed the hypoplasia of all components (10-20%) and the fatty infiltration. We have experienced one case of the idiopathic aplastic anemia in a patient going through hemodialysis and we just report it with documentary records. 저자들은 혈액 투석 중인 환자에서 약물, 면역계 이상등의 원인을 발견할 수 없었음에도 재생 불량성 빈혈이 발생한 1예를 경험하여 문헌 고찰과 함께 보고하는 바이다.

타하르 벤 젤룬의 「신성한 밤」에 나타난 탈식민적 정체성의 탐구

정지용 한국프랑스학회 2011 한국프랑스학논집 Vol.73 No.-

L’image du labyrinthe est très présente dans les romans de Tahar Ben Jelloun, dans la mesure où elle représente bien la situation dans la quelle se trouve le sujet post-colonial. L’enfant de sable et La nuit sacrée, qui racontent la même histoire, celle d’une fille que son père élève comme un homme pour voir un héritier, pose la question de l’identité d’une façon radicale. Or si L’enfant de sable montre l’impossibilité de retourner à soi par sa structure narrative rhizomique, La nuit sacrée tente de reconstruire une identité, bien qu’elle soit ambiguë et hybride, dans un récit rétrospectif. Le père d’Ahmed l’a libéré comme on faisait autrefois avec les esclaves et lui a donné un nom féminin : Zahra. Mais cela ne veut pas dire qu’Ahmed peut retrouver tout de suite sa féminité. Elle a vécu vingt ans en tant qu’homme. Ni un homme, hi une femme, elle devient plutôt un sujet clivé : Ahmed/Zahra. Elle essaie de récupérer sa féminité perdue mais cette tentative lui paraît impossible. Selon Judith Butler, le genre étant construit par le discours social et culturel, il n'existe pas un noyau stable de l'identité sexuelle. C’est par le pacte et la performance qu’elle se construit. Sans pouvoir trouver une place dans la société, Zahra se rend compte qu’elle en est exclue. Dans la situation post-coloniale, la quête de l’identité se lie étroitement avec la question de la construction d’une nation. Comme le montre Homi Bhabha, pour établir une nation homogène, l’état expulse dans un état d’exception les gens qui peuvent troubler le discours national. Ce sont les oubliés que Zahra rencontre au fond du prison. Devenue leur écrivain public, elle s’approprie leur voix dans son corps. Quand elle sort de la prison, elle assume son identité ambiguë et transversale entre deux espaces sexuelles, langagière et culturelle, comme le fait Tahar Ben Jelloun lui- même.

Acute UV Irradiation Increases Heparan Sulfate Proteoglycan Levels in Human Skin

정지용,오장희,김연경,신미희,이다예,정진호 대한의학회 2012 Journal of Korean medical science Vol.27 No.3

Glycosaminoglycans are important structural components in the skin and exist as various proteoglycan forms, except hyaluronic acid. Heparan sulfate (HS), one of the glycosaminoglycans, is composed of repeated disaccharide units, which are glucuronic acids linked to an N-acetyl-glucosamine or its sulfated forms. To investigate acute ultraviolet (UV)-induced changes of HS and HS proteoglycans (HSPGs), changes in levels of HS and several HSPGs in male human buttock skin were examined by immunohistochemistry and real-time quantitative polymerase chain reaction (qPCR) after 2 minimal erythema doses (MED) of UV irradiation (each n = 4-7). HS staining revealed that 2 MED of UV irradiation increased its expression, and staining for perlecan,syndecan-1, syndecan-4, CD44v3, and CD44 showed that UV irradiation increased their protein levels. However, analysis by real-time qPCR showed that UV irradiation did not change mRNA levels of CD44 and agrin, and decreased perlecan and syndecan-4 mRNA levels, while increased syndecan-1 mRNA level. As HS-synthesizing or -degrading enzymes,exostosin-1 and heparanase mRNA levels were increased, but exostosin-2 was decreased by UV irradiation. UV-induced matrix metalloproteinase-1 expression was confirmed for proper experimental conditions. Acute UV irradiation increases HS and HSPG levels in human skin, but their increase may not be mediated through their transcriptional regulation.
