  • 최근 한국경제의 화두가 되고 있는 창업활성화를 위해서 많은 논의와 정책이 이루어지고 있으나, 결국 창업활성화는 창업 기업의 성공률이 높지 않다는 문제가 해결되어야 한다. 특히, 창업초기의 높은 실패율을 낮출 수 있는지의 여부가 창업활성화의 성패를 좌우하는 중요한 요인이 될 것이다. 이에 본 연구에서는 창업 초기기업의 실패 최소화 전략으로서 매우 유용한 시각을 제공하지만 그간 국내 학계에서 체계적으로 연구되지 않은 '린 스타트업'을 살펴보고, 이를 바탕으로 창업기업의 활용방안을 모색해 보고자 하였다. 구체적으로 린 스타트업'의 기본 프레임워크와 핵심원칙에 대한 설명과 함께, 창업기업의 사업추진 단계별 린 스타트업 개념의 적용방법을 사례를 통해 알아보는 한편, 린 스타트업'을 적용하는데 있어서 고려해야 할 사항을 제시하였다. 본 연구는 창업가가 실행할 전략뿐만 아니라 창업 실습을 가르치는 교육자와 창업 기업에 대한 멘토링을 제공하는 전문가들에게 효과적인 프레임웍이 될 수 있도록 전체적인 프로세스를 종합적으로 살펴보았다는 데 의의가 있다.

  • The purpose of this study is to learn from a lesson of the historical fact, the Team 10's break away from the CIAM, which is selected as the most important event in the whole 20th century architecture by author as a historian. The CIAM, organized in 1928 by leading European architects in order to propose new architecture in the industrial era, expanded to the world, met almost annually with an idea of economic efficiency, new functional order, and industrial production for thirty years. Young architects had conflicted with old established group from 6th congress, and after 10th congress they met independently in 1959; the CIAM was disappeared and the Team 10 was born. Main issue of the break-away was human aspect. The Team 10 started from real man, concept of 'human contact', 'sense of community', and 'belonging' instead of abstract functional order. Although CIAM did not suggest inhumane architecture, their biological criteria with sunlight, air, sufficient site became physical determinism. Critique against the Team 10, unsuccess for making humane architecture leads to underestimation like a generational hegemony struggle. However, architect is not specialist of life but form. Historical reevaluation for Team 10 should be that they are the first group to raise an human issue in architecture. Success or not to solve the problem belongs to another domain. After 1960, modern architecture was attacked from the common people, not clients but 'users'. Academic circle tried to solve the problem with behavioral approach through a clear process, 'design method' and with phenomenological approach on real human experience. However practice became reactionary tendency, to make form a little complex, they became post-modern and deconstruction form. Failure of the Team 10's form proved that a complex form does not necessarily make a good life of people. In the Korean historic situation of colony ruling, confusion of liberation, and the War, we did not know the existence of both CIAM and Team 10. After 1970s' economic development, we have just copied Western form from Modern via Post-Modern to Deconstruction. If we make architecture people mattered, we should start from the basic, learning from the Team's break-away, instead of copying.

  • 최근 사이버테러의 급증은 정보사회의 근간을 위협하고 있고, 특히 악성 트래픽에 의한 네트워크마비는 단 시간 내에 국가적인 손실을 초래할 수 있어 이에 대한 대비책이 시급히 요구되고 있다. 이와 관련, 국가사이버안전 위협에 대한 신속한 대처능력확보를 위해 국가사이버위협 조기 예 경보시스템에 대해 많은 연구가 이루어지고 있으나 기술적인 문제와 함께 시스템의 효용성에 대한 한계 때문에 실용적인 연구가 가시화되지 못하고 있는 실정이다. 현재까지는 ESM, TMS 등을 이용한 제한적 자료수집분석을 통하여 보안관리자가 개개인의 경험을 바탕으로 예 경보 판단을 내려왔다. 이러한 판단은 상황에 따라 극히 위험한 결과를 초래 할 수도 있다. 이러한 문제점을 방지하기 위해 본 논문에서는 "지식기반을 이용한 실시간 사이버위협 조기 예 경보시스템"을 제안하였다. 제안된 시스템은 향후 사이버공격에 대해 체계적이고 보다 정확한 예 경보 판단을 내리는데 사용할 수 있다.

  • At least, there are intense pressures on the natural habitats from various disturbance, including urbanization, extension of industrial area, and road construction. These human land use result in fragmentation of landscape and natural habitat. The ecological consequences of habitat fragmentation include the direct effects of habitat loss and the indirect effects of reduced inter-patch dispersal. The decline of biological diversity has been rapidly declined by the habitat loss and fragmentation. Conservation strategists should consider not only the habitat amount of that must be preserved, but also the spatial configuration of habitat across the landscape. But, the paucity of available data for most species forces landscape ecologists to develop the concept, model, and theory. The developed theories are often misused in academic papers and practical applications. The development history, presumption of concept, model, theory is ignored. This tendency have leaded to failure of landscape restoration and the use of theory in conservation practice have come under increasing attacks. This paper will highlight the ecological theory that have proven the most influential in landscape ecology, restoration and conservation : the theory of island biogeography, the theory of nested subset analysis, minimum viable population(MVP), the theory of metapopulation dynamics. And, it find the problem and usefulness of four theory in application to real world. Consequently, the understanding of theoretical implication about landscape ecological theory is required. We must carefully apply the theory after examining the problem and availability of various theory because of no existence of only one general theory.

  • Objectives : The objective of this report is to identify the utilization of hospital school service during hospitalization among patients in their childhood and adolescence with psychiatric disorders. Methods : We retrospectively reviewed the medical record of child and adolescent psychiatric who were hospitalized during March 2009 through October 2012. We compared the one-year successful schooling and outpatient follow up rate between users and nonusers of the inpatient hospital school service. The hospital schooling experiences of the users were investigated upon follow-up visits to the outpatient clinic. Results : Sixty-three students received hospital school service during hospitalization among total 122 child and adolescent inpatients. Hospital school participants showed a significantly higher school reentry rate (61.9%) than non-participants (40.7%). However, there was no difference on follow up rate between the two groups. More than 60% of the 22 interviewed participants expressed an above-average level of satisfaction about hospital school service. Conclusion : Many patients with mental illness experience difficulty in receiving school education during treatment. That induces deterioration in disease, academic failure, poor social skills, low self-esteem, economic difficulties, and future job opportunities. The results of this study emphasize the importance of hospital school service and offer useful guidance for hospital school operation.

  • Purpose: The purpose of this study was to analyze trends in complementary and alternative therapy in nursing research in Korea. Method: The researchers examined academic theses and dissertations published from 1990 to 2002, and 151 articles were used for the analysis. Result: Nursing research on CAT increased rapidly from 1995 Articles with quantitative research designs made up 93.9% of the total and there were more experimental studies than non-experimental studies. Patients who had surgery, mental disorders, renal failure, hypertension, arthritis, dementia & cancer were the most frequently participants in studies on CAT. The type of CAT used in nursing research were mind-body therapy (65.8%), manual healing therapy (28.7%), phamacologic & biological therapy (3.7%), bioelectromagnetics (0.9%) and herbal therapy (0.9%). In 44 articles both psychological and physiological parameters were used as dependent variables. In 34 articles only physiological parameters were used and in 13 only psychological parameters. The most frequently used physiological parameters in CAT were pain, physiological function and vital signs, while the most used psychological parameters were anxiety, depression and stress. Conclusion: More studies about CAT are needed to extend the role and fields for professional nursing. There is a need to conduct qualitative studies in nursing about the experiences of patients who receive CAT and nurses who use CAT.

  • As rural development projects, mostly carried out in a top-down development method in the past came to take a bottom-up development method in earnest, entering the 2000s, resident participation became an essential element of a rural community design project, to the extent that it can influence the success or failure of a rural community design project. It is taken for granted that rural residents independently participate in community design projects, but as they are accustomed to various subsidy projects carried out by the government and become increasingly aging, it is not easy to induce their spontaneous participation in farming areas with such problems. Especially, to prevent the distrust between administrative agencies and residents from serving as an obstacle in the residents' spontaneous participation, it is necessary to construct horizontal governance among the village residents, administrative agencies and the group of experts supporting for the project. This study attempted to verify the mediating effect of governance in the relationship between resident participation and the performance of the rural community design project based on this problem recognition, and for this purpose, the results of a survey with residents in Utturu Village, Hangyeong-myeon, Jeju-si, which was completed by carrying out a comprehensive rural development project, the typical bottom-up community design project was used for an empirical analysis. The results of the study can provide implications for setting directions, establishing strategies and constructing governance of rural community design projects in the future, and especially, it can be said that this study has academic significance in that governance is recognized as an important variable related to the project performance.

  • PURPOSE. This study evaluated the influence of prosthesis weight and number of implants on the bone tissue microstrain. MATERIALS AND METHODS. Fifteen (15) fixed full-arch implant-supported prosthesis designs were created using a modeling software with different numbers of implants (4, 6, or 8) and prosthesis weights (10, 15, 20, 40, or 60 g). Each solid was imported to the computer aided engineering software and tetrahedral elements formed the mesh. The material properties were assigned to each solid with isotropic and homogeneous behavior. The friction coefficient was set as 0.3 between all the metallic interfaces, 0.65 for the cortical bone-implant interface, and 0.77 for the cancellous bone-implant interface. The standard earth gravity was defined along the Z-axis and the bone was fixed. The resulting equivalent strain was assumed as failure criteria. RESULTS. The prosthesis weight was related to the bone strain. The more implants installed, the less the amount of strain generated in the bone. The most critical situation was the use of a 60 g prosthesis supported by 4 implants with the largest calculated magnitude of 39.9 mm/mm, thereby suggesting that there was no group able to induce bone remodeling simply due to the prosthesis weight. CONCLUSION. Heavier prostheses under the effect of gravity force are related to more strain being generated around the implants. Installing more implants to support the prosthesis enables attenuating the effects observed in the bone. The simulated prostheses were not able to generate harmful values of peri-implant bone strain.
