  • 송건호는 기자들을 대상으로 한 설문조사에서 '가장 존경하는 인물'로 선정된 바 있다. 송건호는 언론인으로 활동하며 언론이 정권의 탄압에 굴복하고, 정권의 특혜를 받으며 기업화되는 과정을 직접 경험했다. 그는 1975년에 "동아일보"가 정권의 탄압에 굴복해 기자들을 대량 해고하자 책임감을 느끼고 신문사를 퇴직했다. 그 후 그는 권력과 자본에 종속된 언론에 대해 더욱 예리한 비판을 가했다. 송건호 언론사상의 핵심은 언론이 권력과 자본으로부터 독립해 민족주의와 민주주의에 기여해야 한다는 것이다. 또한 그는 언론인이 기능인과 같은 역할만을 하는 것을 넘어서서 역사의식과 사회과학적 지식을 갖추고 활동해야 한다고 주장했다. 그의 언론사상은 또 다시 언론의 독립이 위태롭고 언론인의 기능인화가 드러나는 현재의 언론 현실에서도 여전히 유효하다. 그의 언론활동과 언론사상을 살펴보는 것은 미디어 환경의 변화 속에서 언론의 올바른 역할과 언론인의 바람직한 자세를 모색하는 데 도움을 줄 수 있을 것이다.

  • The accident which is caused by the press work remains a Permanent obstacle in worker's hand or arms, the disaster ratio is high and the fatal case is many. Mainly Like this accident occurs because the hand to enter with inside of the press die, therefore, basic countermeasure is the safety press. In order to prevent access to mechanical moving part by the hand or any part of the body, it is important to making a safety die design Structurally. It presents the design of the safety press die with suitable structure in the Product's attribute which it had shown in samples, There is a possibility of being difficult because the attribute of safety die design that had present all the productions from research does not agree each other. but because the representative process which is used most at sample had designed, If you were imitates with safety die design base which is presented from this research, It comes to be thought to be the part which can are used at the various sides.

  • Although the transfer forming process has various advantages, it is also inefficient for the use of multiple press machines, especially for small part sizes. In this study, a new forming process was proposed to use multiple tandem dies in a single press machine. A rotary transfer forming device was developed to combine the advantages of the progressive and transfer forming process. In this study, a detailed forming process using this device was analyzed, and the device was designed to perform four series of tandem forming processes in a single press. In order to analyze the feasibility of this forming process, simple forming dies were made. As a result, the position accuracy was 4 arcsec, and the forming speed reached up to 20 strokes per minute. It is thought that this rotary transfer forming device can help to save initial setup costs through the more efficient use of space in a press machine.

  • Many studies have emphasized the importance of resistive exercise to maintain a healthy human body, particular in prevention of weakening of physical strength. Recently, some studies advocated that an application of vibration as a supplementary means in a regular training was effective in encouraging physical strength. Aim of the current study was, therefore, to identify if an application of vibration in a resistive exercise was effective in encouraging physical strength as that in a regular training. A 3-dimensional virtual lower extremity model for a healthy male and virtual leg-press model were generated and synchronized. Dynamic leg-press exercises on a slide machine with/without extra load and on a footboard with vibration as well as on a slide machine with extra load were analyzed. The results of the current indicated that the application of the vibration on the dynamic leg-press exercise might be not greatly effective in encouraging physical strength, compared with the dynamic leg press exercise with extra load. It was, however, thought that the application of the vibration might be helpful to elderly individuals because the reduced maximum muscle strength appeared by the effect of the vibration may avoid a muscular spasm, which can be driven from a high muscle strength sometimes produced during the leg-press exercise with extra load.
