본 논문에서는 DirectShow 프로그래밍의 주요 개발 도구인 그래프 에디터에서 작성된 필터 연결 그래프로부터 C 소스 코드를 자동 생성하는 시스템에 대한 설명한다. 기존의 DirectShow 프로그래밍 환경에서는 그래프 에디터를 이용한 프로그램 설계 및 실행 확인 작업과 실제 프로그램 코드를 작성하는 프로그램 개발 작업이 별도로 이루어진다. 이에 반해, 본 시스템을 사용할 경우, 멀티미디어 응용 프로그램 개발자는 소스 코드를 직접 일일이 수정할 필요 없이, 그래프 에디터를 이용하여 필터 삽입 및 필터 연결을 통한 프로그램 설계 작업을 수행한 다음, GRF 파일로 저장하기만 하면, 원하는 C 소스 프로그램을 자동적으로 얻을 수 있기 때문에 보다 효과적이고 훨씬 신속한 DirectShow 프로그래밍이 가능하다. 더욱이 본 시스템은, 고정된 개수의 매우 제한된 미디어 제어 기능만을 소스 코드에 추가할 수 있는 기존의 시스템과는 달리, 시스템 사용자인 프로그램 개발자로 하여금 자신이 개발하고자 하는 응용 프로그램에 추가할 미디어 제어 기능을 보다 쉽고 다양하게 선택할 수 있도록 지원하기 때문에 보다 실용적인 도구로 활용될 수 있다.

It is well-known that the strength properties of wood connections depend on the density of the wood members, the diameter of the fasteners, the number of fasteners, and the arrangement of the fasteners, etc. In this study, the connection with inserted steel plates and drift pins was made in different configurations. The specimens were Larch and Sugi glulam connections. The specimens were loaded in tension, and the yield loads of the connections were obtained. The values obtained from the tests were compared with the predicted values. Good agreement between the yield loads obtained from the tension failure tests and the predicted yield loads were shown. It was shown that the density of the wood member barely affected the strength properties of the connections. The strength decreases of the Sugi glulam connections by the group effect were less than those of the Larch glulam connections.

Objectives: The purpose of this study is to comprehensively compare the trends of health administration and health policy in the field of health care using the semantic network analysis in the inaugural address of the Ministry of Health and Welfare of each regime in Korea. Methods: This study used a language network analysis method that uses Korean Key Words In Context (KrKwic) program and NetMiner program in sequence. The analysis was conducted by Minister Hwa-joong Kim during the Moo-hyun Roh government, Minister Jae-hee Jeon during the Myung-bak Lee government, Minister Young Jin of Geun-hye Park government and Government Jae-in Moon's inaugural address of Neung-Hoo Park Minister, respectively. Results: The key words differentiated by each regime are that the Moo-hyun Roh Government's Minister Hwa-joong Kim had high connection centrality values in the words 'balanced development', 'comprehensive' and 'reform'. Minister Jae-Hee Jeon of Myung-bak Lee Government had high connection centrality values in the words 'poverty' and 'return'. In the case of Minister Young Jin of Geun-hye Park Government had high connection centrality values in the words 'demand', 'Customized' and 'Life cycle'. In the case of Minister Neung-Hoo Park of Jae In Moon Government had high connection centrality values in the words 'Welfare state', 'Embracing' and 'Soundness'. Conclusions: If the role of health administration in the health care field and the health care policies are constantly changed according to the policies of each regime, it is inconsistent and it is difficult to approach from the long term perspective for public health promotion. In the future, health policy should be developed and implemented with a long-term perspective and consistency based on the consensus and participation of the people with less influence on the change and direction of each government's policies.

In this paper, the identification of connections for a vibration system has been presented using FRF-based substructural sensitivity analysis. The substructural design sensitivity formula is derived and plugged into a commercial optimization program, MATLAB, to identify connection stiffness of an air-conditioner system of passenger car. The air-conditioner system, composed of a compressor and a bracket is analyzed by using FRF-based substructural(FBS) method. To obtain the FRFs, FE model is built for the bracket, and the impact hammer test is performed for the compressor. Obtained FRFs are combined to calculate the reaction force at the connection point and the system response. Connection element properties are determined by minimizing the difference between a target FRF and calculated one. It is shown that the proposed identification method is effective even for a real problem.

A single plate shear connection, or shear tab, is a very popular shear connection due to its merit in ease of construction and material economy. However, problems in understanding the connection behavior, both in terms of strength and ductility, have been well-documented. Suggestions or design model for single plate connections in AISC Design Manual have been altered several times, with the latest edition settling down to giving designers pre-calculated design strength tables if the connection details agree with given configurations. Results from many full-scale tests and finite element models in the past suggest that shear strength of a bolt group in single plate shear connections might be affected by yield strength of plate material; therefore, this research was aimed to investigate and clarify effects of plate yield strength and thickness on shear strength of the bolt group in the connections, including the validity of using a plate thickness/bolt diameter ratio ($t_p/d_b$) in design, by using finite element models. More than 20 models have been created by using ABAQUS program with 19.0- and 22.2-mm A325N bolts and A36 and Gr.50 plates with various thicknesses. Results demonstrated that increase of plate thickness or plate yield strength, with the $t_p/d_b$ ratio remained intact, could significantly reduce shear strength of the bolt group in the connection as much as 15 percent. Results also confirmed that the $t_p/d_b$ ratio is a valid indicator to be used for guaranteeing strength sufficiency. Because the actual ratio recommended by AISC Design Manual is $t_p/d_b$ + 1.6 (mm) for connections with a number of bolts less than six and plate yield strength in construction is normally higher than the nominal value used in design, it is proposed that shear strength of a bolt group in single plate connections with a number of bolts equal or greater than seven be reduced by 15 percent and the $t_p/d_b$ ratio be limited to 0.500.

오늘날 인성교육의 중요성이 높아짐에 따라 과학교육에서도 인성교육을 실시하고자 하는 노력이 계속되고 있다. 이에 이 연구에서는 NABI 프로그램 적용을 통해 이론적으로 개발된 '실천 중심의 인성발현 메커니즘'이 실제 과학교육에서 구현 가능한지 확인하였다. 이를 위해 학생 산출물과 수업 녹화 자료 등 다수의 질적 자료를 수집하였고 이를 '실천 중심의 인성 발현 메커니즘'의 단계인 '가치, 판단, 실행'의 과정으로 유목화한 뒤 그 의미를 해석하였다. 연구 결과, 학생들은 NABI 프로그램에서 대상을 선정하고 개별적 관계를 맺음으로써 '가치'를 형성해가는 모습을 보였다. 또한 학생들이 형성한 가치는 '관계맺음'의 대상에 따라 '개인적, 대인적, 사회적, 생태적, 영적 가치'가 나타났지만 자연을 대상으로 하는 NABI 프로그램의 특성 상 생태적 가치가 두드러진 모습을 보였다. 다음으로 학생들은 실제 상황에서 겪게 된 문제를 '판단'하는 모습을 보였는데 이 과정을 통해 학생들은 서로 타협하는 사회적 가치를 형성하고 실행하는 모습을 보이기도 했다. 마지막으로 '실행' 단계에서는 대상에 대한 공감을 바탕으로 '실천 의지'가 발휘될 때 진정한 '실행'이 이루어지는 것이다. 이를 통해 이론으로서의 '실천 중심의 인성 발현 메커니즘'은 과학교육에서 NABI 프로그램을 통해 구현될 수 있다는 사실을 확인하였다. 앞으로 NABI 프로그램은 과학교육을 통한 인성교육 실행에 구체적인 방안으로 활용 가능할 것이다.
