사회적 규제가 대체재 간 경쟁과 혁신에 미치는 영향에 관한 연구 : 국내 철강 구조물용 내화 피복재 산업의 사례연구

장철권,지일용 한국기술혁신학회 2017 기술혁신학회지 Vol.20 No.4

The interest in social regulation and its influence on innovation are increasing as the society concerns more for environment and safety. There have been plenty of literature about the impact of social regulation on innovation and its mechanism. Majority of research have been influenced by or based on the famous Porter’s hypothesis. However, majority of the literature focus on internal factors such as expected benefits from change of regulations, and it is hard to find one studying social regulation’s influence on innovation through external factors such as market or industrial structure. This study addresses this issue of the impact of social regulation on innovation by analyzing the case of fire-retardant coating material for steel structure industry in Korea. It scrutinizes the impact of social regulation which affects competition and innovation on substitute competing market, and tries to reveal that there might exist the other path to innovation, besides the way that the expected benefit from compliance of regulation directly drives innovation. As a result of the case study, we have found that changes in social regulation may act like economic regulation and restructure the market segment and this effect may lead to innovation. It can be explained by the fact that expected benefits from compliance of regulation can be a direct source of innovation, as Porter suggested, but the change of industry structure and competitive strength caused by the change in social regulation can also act as a driving force of innovation. 환경과 안전에 대한 관심이 증가함에 따라 사회적 규제 및 이의 혁신에 대한 영향성에 대한 관심 또한 증대되고 있다. 포터가설을 중심으로 한 기존의 사회적 규제 관련 문헌들은 주로 혁신으로 인한 비용, 기대이익, R&D 투자 등 내적 요소에 초점을 두어 왔다. 최근에는 환경규제 등 사회적 규제로 인한 산업구조의 변화에 관심을 두는 연구가 증가하고 있는 상황이나, 사회적 규제에 따른 외부환경의 변화와 그로 인한 혁신에 대한 영향에 대해서는 연구가 많이 이루어지지 못한 상황이다. 이에 본 연구에서는 기존 문헌이 제시하는 바와 같이 준수 기대이익 등 내적 요인은 물론, 산업구조 변화와 같은 변화를 통해 사회적 규제가 혁신에 영향을 미칠 수 있음을 보여주고자 하였다. 이를 위해 본 연구에서는 국내 철강 구조물용 내화 피복재 산업의 사례연구를 실시하였다. 연구 결과 내화 피복재 산업은 1990년대 3번에 걸친 규제완화를 경험하였으며, 이들 규제 완화들이 시장 기회 및 기대이익을 제공함으로써 신규 시장진입을 유도하였고, 시장구조 변화와 경쟁 심화에 따라 기업들의 혁신이 발생하였음을 확인할 수 있었다.

양대중,장일용,박승규,이준희,강정일,천동환,Yang, Dae-Jung,Jang, Il-Yong,Park, Seung-Kyu,Lee, Jun-Hee,Kang, Jung-Il,Chun, Dong-Hwan 대한물리치료학회 2011 대한물리치료학회지 Vol.23 No.5

Purpose: The purpose of this study was to investigate the kinematic characteristics and muscle activities during the following two conditions: transition from half-kneel to standing on the affected leg and non-affected leg. Methods: Twenty-one hemiplegic patients participated in the study. A motion analysis system was used to record the range of motion and angle velocity of the hip, knee and ankle from the half-kneel to the standing position. Electromyography was used to record the activity of 4 muscles. Results: The statistical analysis showed that the minimum ROM of the hip joint was less on the affected leg during transition from half-kneel to standing. However, the minimum ROM of the knee and ankle joints was less on the non-affected leg during transition from half-kneel to standing. The angle velocity of the knee and ankle joints was less during transition from half kneeling to standing on the non-affected leg. Muscle activity of the rectus femoris and tibialis anterior was less while moving from half-kneel to the standing position on the affected leg. Conclusion: These results show that greater active ROM of the knee and ankle was required on the affected leg for transition from half-kneel to the standing position than for normal gait. Muscle activity of the rectus femoris and tibialis anterior is normally required for movement from the half-kneel to the standing position during normal gait. Further studies are needed to investigate the antigravity movement in healthy subjects and hemiplegic patients in order to completely understand the normal and abnormal movement from the half-kneel to the standing position.

안응섭,장일용,이재강,김일환 江原大學校 産業技術硏究所 2001 産業技術硏究 Vol.21 No.B

According as the patterns of PCB (Printed Circuit Board) became denser and complicated, quality and accuracy of PCB influence the performance of final product. It's attempted to obtain trust of 100% about all of parts. Because human inspection in mass-production manufacturing facilities are both time-consuming and very expensive, the automation of visual inspection has been attempted for many years. Thus, automatic visual inspection of PCB is required. In this paper, we used an algorithm which compares the reference PCB patterns and the input PCB patterns are separated an object and a scene by filtering and edge detection. And than compare two image using pattern matching algorithm. We suggest an defect inspection algorithm in PCB pattern, to be satisfied low cost, high speed, high performance and flexibility on the basis of 640×480 binary pattern.

Purpose : The purpose of this study is to assess changes in the circulatory system according to the tempo of music while performing treadmill exercises. Methods : This study selected a total of 21 healthy students (ten male and eleven female) in the department of physical therapy at Gwangju Health University. Participants exercised for 30 minutes once a week for a total of three weeks. Participants’ heart rate, autonomic nervous system activity, and blood pressure were measured at pre-test and post-test intervals. In the first week, treadmill exercise was completed without music. In the second week, we applied slow tempo music (60~80 bpm) while using the treadmill, and in the third week, we applied fast tempo music (120~140bpm). The measured data were analyzed by repeated-measurements ANOVA using the before and after values for each music tempo. The results are displayed as differences between the three groups. Results : There were no significant differences in heart rate, systolic blood pressure, diastolic blood pressure, or RMSSD (autonomic nervous system) between the three groups. There was a significant difference in LF/HF (autonomic nervous system) between the three groups. Conclusion : According to our results, there was some evidence for music tempo benefiting the autonomic nervous system during exercise. However, there is a need for more study on this subject. Continued research on this subject could provide benefits to the science of physiotherapy as it relates to cardiopulmonary treatment.
