Throughout this paper, we denote that R is a near-ring and G an R-group. We initiate the study of R-substructures of G, representations of R on G, monogenic R-groups, faithful R-groups and faithful D.G. representations of near-rings. Next, we investigate some properties of monogenic near-ring groups, faithful monogenic near-ring groups, monogenic and faithful D.G. representations in near-rings.

Throughout this paper, we denote that R is a near-ring and G an R-group. We initiate a study of R-substructures of G, monogenic R-groups, faithful R-groups and faithful D.G. representations of near-rings. Next, we investigate some properties of monogenic R-groups, faithful monogenic R-groups and a generalization of annihilator concepts in R-groups.

Throughout this paper, we will consider that R is a near-ring and G is an R-group. We initiate the study of monogenic and strongly monogenic R-groups and their basic properties. Also, we investigate some properties of D.G. R-groups, faithful R-groups and monogenic R-groups and we determine that when near-rings are rings.

In this paper, we will introduce the noetherian quotients in R-groups, and then investigate the related substructures of the near-ring R and G and the R-group G. Also, applying the annihilator concept in R-groups and d.g. near-rings, we will survey some properties of the substructures of R and G in monogenic R-groups and faithful R-groups.

In this paper, we will introduce the noetherian quotients in R-groups, and then investigate the related substructures of the near-ring R and G and the R-group G. Also, applying the annihilator concept in R-groups and d.g. near-rings, we will survey some properties of the substructures of R and G in monogenic Rgroups, and show that R becomes a ring for faithful monogenic R-groups with some condition.

최근 정부의 벤처기업 정책 지원은 창업 초기 중기의 벤처기업에 대한 R&D 지원에 초점을 두고 있다. 그러나 정보의 비대칭성 문제로 인한 역선택 가능성, 즉, 정부 R&D가 과연 성장 잠재력이 높은 창업 초기 중기 기업에게 지원되고 있는가에 대한 우려도 제기되고 있다. 특히 창업 중기는 죽음의 계곡으로 인해 벤처기업의 생존율이 크게 낮아지는 구간이기 때문에, 정책효과가 클 것으로 예상되는 우수 벤처기업을 선정하여 지원하는 것이 매우 중요하다. 이에 따라 본 연구는 2015년 벤처기업정밀실태조사 결과를 활용, 기술집약적 제조업 내 중기 벤처기업을 정부 R&D 지원 수혜기업(이하 수혜기업)과 비수혜 기업으로 나누고, 이들의 경영효율성 및 기술 재무성과를 비교하였다. 분석결과, 기술집약적 제조업 내 수혜기업은 비수혜 기업에 비해 경영효율성이 낮았으며, 이러한 경향은 중고위기술 제조업에서 더욱 크게 나타났다. 한편, 기술 및 재무성과 분석 결과, 수혜기업은 기술성은 우수하였으나, 성장성, 수익성, 안정성은 열위에 있음을 확인하였다. 특히 이러한 경향은 중고위기술 제조업 내 세부산업 전반에서 발견되었다. 이는 벤처기업에 대한 정부 R&D 지원 시, 역선택 문제가 우려됨을 시사한다. 따라서 향후 정부는 수혜기업 선정 시 경영효율성 및 재무성과를 중요 평가 기준으로 고려해야할 것이다. 또한 기술성이 뛰어난 기업의 경영효율성 및 재무성과를 제고하기 위한 정책과 함께, 경영효율성이 뛰어난 벤처기업을 정부 R&D 지원에 유인하기 위한 방법도 마련해야할 것이다.

Throughout this paper, we will consider that R is a near-ring and G an R-group. We initiate the study of monogenic, strongly monogenic R-groups, 3 types of nonzero R-groups and their basic properties. At first, we investigate some properties of D.G. (R, S)-groups, faithful R-groups, monogenic R-groups, simple and R-simple R-groups. Next, we introduce modular right ideals, t-modular right ideals and 3 types of primitive near-rings. The purpose of this paper is to investigate some properties of primitive types near-rings and their characterizations.

This paper originates from the questions concerning why Korea has had difficulties in boosting R&D service industries regardless of government efforts over a decade. We first review the intrinsic nature of the R&D services and set up four criteria such as establishment type, diversification of business models, coverage of client firms, and role of R&D service firms as innovation drivers and IP strategies, that will be used in interviewing and analyzing R&D service firms. Second, we carry out in-depth interviews of eighteen R&D service firms to understand business behaviors and relevant characteristics. Finally, we identify five groups of R&D service firms and conclude that differentiated polices have to be implemented according to the groups for promoting the industry effectively.

The two groups of research and management staff working in the government-supported research institutes are shown different in their cognitive styles on R&D management. Identifying the differences and understanding the reasons why such differences exist are th prerequisites for working out an effective R&D management. The investigation was made with emphasis on the cognitive styles regarding the core elements of R&D managements such as R&D process, manpower, budget and information required for R&D activities. The cognitive styles on R&D management shown distinct between the two groups suggest in turn that narrowing down the diference could provide the way to more effective R&D management.
