This study examines the relationship of the industry-specific factors that effect innovation of manufacturing technology and the market share within the defense industry. Since the establishment of the basic defense industry framework in 1973, there were numerous interactions of the industry-specific factors of the defense industry structure with the technological innovation and market organization of the defense industry. During last three decades, the domestic defense industry has achieved the considerable level but the framework of the basic system has not developed much in areas of the military science and the defense manufacturing technology. Industry-specific factors were formed in the process and appeared in a variety of behavioral characteristics as subsystems. Currently, there IS a growing trend where the management of defense industry is gradually deteriorating due to limitation of the domestic industry-specific factor (e.g. defense technologies, amount of demand, etc.). If there is a prominent imbalance of the industry-specific factors. it can trigger the potential problem of conflict, lack of cooperation and control, slowing the growth of the manufacturing technology thereby diminishing the market and deteriorating the defense supply/demand relationship. In a research conducted by Joe S. Bain, Bain analyzed the relationship of the traditional industrial organization where industry-specific factor(S) not only impacts the conductor(C). And, conductor(C) influences the shaping of the performance(P) of relationship of the traditional industrial organization. Consequently, the researcher has identified the demand monopoly, barriers to entry, and market competition with comparison of defense industry issues. These defense issues were three industry-specific factors identified, which are 1) The demand monopoly and The entry barriers to new market competition, 2) the industrial technical factor to a production technical competitiveness and a market sharing competitiveness, 3) the probability factor to revolution for military affairs(RMA) and a R&D production. According to baseline with these factors, the following research model is established from the special companies group(Group A), the systematization companies group(Group B), and the general companies group(Group 0. The hypothesis is that if there are more industry-specific factors, then there will be more relationships of defense industry relation statutes. This research is an empirical study on the relationship that the industry specific factors effects the innovation of manufacturing technology and the shaping of the market in the defense industry. Moreover, the existing models to evaluate the industry specific factors of the defense industry IS much to be desired with the controlled statistical analysis of the result. It is vital to study on current situation with suggesting alternative strategy to the efficient strategy. The descriptive analysis approach analysis is conducted with SPSSWIN to conduct reliability test, factor analysis, correlation analysis, cross-tabulation analysis, one-way ANOVA, and multiple regression analysis. However, there were some limitations of the survey such as the rigidity of concept about the technical factors and various market management factors. The wishes is that the decision-maker could be utilized these defence industrial factors to formulate efficient defence policy and strategy in the future.

재식밀도를 달리할 때 얼자제거가 단옥수수의 생육 및 수량에 미치는 영향을 구명하고자 단옥 1호와 Golden Cross Bantam 70(GCB 70)을 10a 당 4167, 5557,6667,8333, 11111 개체 재식하여 얼자의 초장이 15cm 이내일 때 얼자를 제거하는 구와 제거하지 않은 구의 생육 수량 등을 조사한 결과를 요약하면 다음과 같다. 1. 두 교잡종 모두 재식밀도가 증가할수록 개체당 얼자수는 직선적으로 감소되었다. 2. 간장, 수장, 수경, 개체당 및 10a 당 이삭수는 교잡종간에 차이가 없었다. 단옥 1호는 10a 당 8333본 이하 재식구에서 약 20％ 근도복이 되었으나 GCB 70은 재식밀도에 관계없이 도복이 전혀 되지 않았다. 엽년적지수 및 간엽수량은 단옥 1호가 GCB 70보다 컸었다. 3. 근도복과 엽면적지수를 제외하고는 교잡종과 재식밀도간 교호작용이 없었다. 4. 재식밀도가 증가할수록 간장, 엽면적지수 및 간엽수량은 직선적으로 감소하였다. 재식밀도 증가에 따른 엽면적지수의 증가는 GCB 70보다 단옥 1호에서 컸었다. 5. 재식밀도와 10a 당 이삭수 및 이삭수량과는 이차곡선적인 증가 관계가 있었으며 이상수량, 10a 당 이삭수, 이삭크기 등을 고려한 적정재식밀도는 10a 당 6500 본 정도로 판단되었다. 6. 착수고와 엽면적지수를 제거하고는 교잡종과 얼자제거, 재식밀도와 얼자제거간에 유의한 교호작용이 없었으며 교잡종, 재식밀도, 얼자제거간에는 어떠한 형질에도 유의한 교호작용이 없었다. 7. 얼자제거에 의하여 간장, 이삭수량 및 간엽수량이 각각 3, 10, 16％ 감소되었으나 출사기, 근도복, 수장, 수중, 본당 및 10a당 이삭수 등은 크게 영향을 받지 않았다. 8. 따라서 얼자제거를 하거나 제거를 하지 않거나 간에 적정재식밀도는 10a 당 6500 본 정도로 생각되며 교잡종, 재식밀도에 관계없이 얼자를 제거하지 않은 것이 유리할 것으로 판단되었다.
