The purpose of this study is to introduce a empirical study of using Taguchi Method for the Entrepreneurial Orientation and Financial Performance. In this study, three factors of Entrepreneurial Orientation, innovation, pro-activity and risk taking, are used of the control factors and an element, period of establishment, is chosen as a noise factor. In order to carry out this research, we obtained 200 survey sheets and performed the reliability and validity analysis of the questionnaires and then the experiment was conducted by Taguchi's experimental design. To improve Financial Performance under the noise factor of period of establishment, optimal condition are as follows; the two factors of Entrepreneurial Orientation, innovation, pro-activity should be maintained to a high level. Also, other factor, risk taking should be performed as the level that the company has maintained. Through this paper, we find out that Taguchi method is applicable for analysis of questionnaire.

이동통신 사용인구의 급증함에 따라 가입자의 욕구를 충족시켜 줄 수 있는 서비스도 그만큼 더 늘어나고 있다. 그리고 서비스 업체의 통신망 성능(Network Performance)과 서비스 품질 향상(Quality of Service)에 많은 인력의 노력과 투자를 집중하고 있는 시기에서 효과적으로 네트워크를 관리하고 분석하여 기지국 및 이동통신 교환기 시스템을 원활하게 Maintenance를 지원할 수 있는 Worst cells 프로그램을 개발하였다. 각 기지국의 소통율(Establishment Rate)과 절단율(Dropped Call Rate)의 통계를 측정하여 관리함으로서 장애를 미리 예측하여 조치를 취할 수 있는 기지국 성능 분석 프로그램 개발로 인하여 시스템 공급 업체(system provider)의 신뢰도와 서비스업체(service provider)의 이미지 제고에 기여 할 수 있다고 본다.

Recently, the cluster-based industrial policy has become a powerful policy tool for strengthening the competitiveness of nations, industries and firms. The concept of cluster develops as firms choose to locate in each others proximity. Cluster concept can be usefully applied to analyze cluster of port-related activities. Port cluster can be used as a systematic foundation for providing one-stop value added logistics service to its customers. The main purpose of this paper is to suggest a way for establishing the port cluster in Korean seaport. For this aim, the paper defines a concept of port cluster and examines the its necessity. And the procedure for establishment of port cluster in Korea is proposed. In addition, the paper analyzed the port cluster structure-conduit-performance. Especially, the role of port cluster's participants, central and local government, universities and related R＆D institutes, and private companies, are suggested respectively. As a conclusion, policy suggestions for the establishment of port cluster in Korea are suggested.

After the THAAD crisis, Goyang city's Global Medical Service performance is showing a sharp decline compared to other cities and provinces. In particular, the contraction of participants who can create policy outcomes such as Medical Institutions and Attracting companies has emerged as the biggest problem. Therefore, Goyang City wanted to derive effective marketing policies and establish marketing policies according to their priorities in order to prevent the deaths of the future patient visitor market as well as performance. In order to examine such policy needs more closely, this paper reviewed the Global Medical Service policies of Goyang City based on AHP analysis, and derived a ranking of 28 major policies and preferred policies for each participant. In the future, Goyang City is expected to derive major policy effects by applying the results of this study to the establishment of marketing policies through customized policies for each medical institution type and Patient attraction company.

In this paper, we propose a establishment of system level environment to exploit PC system with SSD (Solid State Disk) by using TLM (Transaction Level Modeling) method with SystemC language. The reason why we choose this modeling method is that it eases RTL (Register Transfer Level) modeling burdens and we can accurately estimate the performance about different architectural changes. Also, it provides simulation speed which is relatively faster than RTL modeling method. The baseline architectural platform we implemented showed that SSD's internal transfer time is a dominant factor, so we need to improve that part and it is expected to be a good simulator to measure the system's overall performance by exploiting SSD's internal architectures.

최근 공연예술에서 장르 융합형 콜라보레이션과 기술 융합형 콜라보레이션의 물리적인 융합(convergence)은 서로 다른 목표와 이질적인 속성을 전략적으로 융합시킴으로서 대중의 기대수요에 부응하며 새로운 가치의 융합 콘텐츠를 이끌어내는 실험적인 형태로 발전하고 있다. 융합시도 중 발생되는 문제점을 보완하며 공연의 완성도를 높이기 위해서는 각 매체분야 전문가들의 효율적인 협업과정이 연구되고 개선되어야 한다. 본 논문에서는 다매체 융합공연 프로토타입(Prototype) 제작을 통해 시대의 요구에 상응하는 융합공연의 효율적인 협업제작방안을 연구하고자 한다. 공연제작과정을 프리프로덕션(Pre-Production), 프로덕션(Production)으로 분류하여 라이브 연극과 사전제작 영상 애니메이션, 두 매체를 활용한 융합공연의 효율적인 협업제작과정을 작품선정 및 연출방향 설정, 인적구성, 제작일정 계획수립, 시각화과정, 공연연습 및 리허설 등의 과정으로 연구하고자 한다. 융합공연 콘텐츠 기획, 제작방식의 변화, 융합 콘텐츠 간 특수성의 이해를 바탕으로 지속적인 다매체 융합공연을 위한 효율적인 협업제작과정 연구가 진행되어야 융합 콘텐츠 산업 발전 체계화 및 활성화가 가능할 것이다.

In this paper, we propose a symmetric key establishment scheme for wireless sensor networks which tries to minimize the resource usage while satisfying the security requirements. This is accomplished by taking advantage of the communication pattern of wireless sensor networks and adopting heterogeneous wireless sensor networks. By considering the unique communication pattern of wireless sensor networks due to the nature of information gathering from the physical world, the number of keys to be established is minimized and, consequently, the overhead spent for establishing keys decreases. With heterogeneous wireless sensor networks, we can build a hybrid scheme where a small number of powerful nodes do more works than a large number of resource-constrained nodes to provide enhanced security service such as broadcast authentication and reduce the burden of resource-limited nodes. In addition, an on-demand key establishment scheme is introduced to support extra communications and optimize the resource usage. Our performance analysis shows that the proposed scheme is very efficient and highly scalable in terms of storage, communication and computation overhead. Furthermore, our proposed scheme not only satisfies the security requirements but also provides resilience to several attacks.

The effects of coating materials on germination, establishment and herbage production were investigated in a laboratory and field over 1988-1989. For this purpose, four treatments of lime 50 % + briquet ash 50 %, briquet ash, dairy excreta and fowldung as coating material were applied to orchardgrass and red clover with meth ylcellulose. The germination rate of lime 50 % + briquet ash 50 % (70.6 %), briquet ash (84.0 %), dairy excreta (66.0 %) and fowldung (61.3 %) in orchardgrass were, showing lower than that of the control (86.6 %), respectively and the rate of red clover ranged from 59.0 to 18.6 %. Establishment in orchardgrass were from 2.0 to 0.9 %, showing lower than the control, whole a little higher except dairy excreta and fowldung treatments in red clover than the control. The DM yield of lime 50 % + briquet ash 50 % treatment was almost same to the control and other treatment showed lower yield compared with the yield of the control. The benefical effect of seed coating on field performance was minimal especially in terms of establishment and yield increase.
