피트니스 분야 인공지능 서비스의 성능 개선을 AI모델 개발이 아닌 데이터셋의 품질 개선을 통해 접근하는 방식을 제안하고, 데이터품질의 성능을 평가하는 것을 목적으로 한다. 데이터 설계는 각 분야 전문가 10명이 참여하였고, 단일 시점 영상을 이용한 운동동작 자동 분류에 사용된 모델은 Google의 MediaPipe 모델을 사용하였다. 팔굽혀펴기의 운동동작인식 정확도는 100%로 나타났으나 팔꿉치의 각도 15° 이하였을 때 동작의 횟수를 인식하지 않았고 이 결과 값에 대해 피트니스 전문가의 의견과 불일치하였다. 향후 연구에서는 동작인식의 분류뿐만 아니라 운동량을 연결하여 분석할 수 있는 시스템이 필요하다.

Korea's innovation cluster policy has been implemented since 2005 with the goal of balanced regional development. The purpose of this study is to investigate the factors affecting the sustainability of innovative cluster tenants by using Pangyo Techno Valley as an example. Pangyo Techno Valley was established under the leadership of the local government (Gyeonggi-do) rather than the central government and it is called "Silicon Valley of Korea" and "Asia Silicon Valley" and is becoming more representative. The growing number of companies in Pangyo Techno Valley decreased in 2017 compared to 2016. This is because Pangyo Techno Valley's business ecosystem will change from 2019. In this paper, quantitative and qualitative studies were conducted to investigate the influencing factors. Quantitative research was conducted based on the survey and qualitative research was applied through interviews. The quantitative research examined the factors affecting the sustainability of Pangyo Techno Valley, and the qualitative research examined the specific reasons and additional factors for the quantitative research results. The quantitative results showed that factors affecting sustainability in terms of changes in corporate internal conditions, human and physical infrastructure, cooperation and synergy, and occupancy patterns. The specific reason for the impact appeared in the qualitative research process. The support category of local governments did not show any significant factors in quantitative research. In addition, qualitative research suggested 'Good image of Pangyo Techno Valley' as the category that has the greatest impact on sustainability. It is shown that companies are passive and expect the role of local governments in activating cooperation network in Pangyo Techno Valley. In this paper, based on the results of the study, Pangyo Techno Valley is presented with a realistic plan based on real estate issues and an ideal plan with a long-term perspective.

To reduce the hydrogen production cost through the utilizing the oxygen and improving the capacity factor of water electrolysis used to energy storage of renewable energy, the hybrid hydrogen production process which has dual operating concept of using the water electrolysis as energy storage and oxygen production process for biomass gasification was proposed. Moreover, Techno-economic analysis on this system was quantitatively performed.

Purpose: The purpose of this study was to investigate the effect of 7Hz vibration on the thickness of the rectus femoris, medial femur, rectus femoris tendon, and Achilles tendon. Methods: The statistical methods before and after working around the average value of each of the legs included repeated measures ANOVA. The subjects were 26 males residing in the N area, and we measured the change in muscle thickness and tendon thickness before, four weeks, and eight weeks after the experiment in two groups of 13 subjects each. The analysis method was a two-way repeated measurement variance analysis (ANOVA) with a significance level of 0.05 Results: The rectus femoris, medial broad muscle, rectus femur, and Achilles tendon showed significant increases in the interaction between the periods as well as between the periods and groups (p < 0.05). Conclusion: As a result of this study, the 7Hz vibration had a positive effect on the thickness of the rectus femoris and the vastus medialis muscle as well as the thickness of the rectus femoris tendon and Achilles tendon. It is expected to be used as basic data for vibrational exercises in the future studies and is expected to be used as an exercise to strengthen the leg muscles and tendons.

Purpose: This study investigated the immediate effects of a figure-8 shoulder brace and taping intervention on round shoulder posture, thoracic kyphosis, and chest expansion mobility in forward head posture. Methods: Thirty patients with forward head posture were assigned randomly to the figure-8 shoulder brace group (n = 15) or the taping intervention group (n = 15). Patients were assessed for forward head posture, shoulder posture, thoracic kyphosis, and chest expansion. Results: The figure-8 shoulder brace and taping intervention groups showed a significant difference for forward head posture, shoulder posture, and thoracic kyphosis after the experiment (p < 0.05). There was no significant difference between the groups (p > 0.05). Conclusion: These results suggest that a figure-8 shoulder brace and taping intervention has a positive effect on rounded shoulder posture, thoracic kyphosis, and chest expansion in patients with forward head posture.

건설은 경제 발전과 일자리 창출에 중요한 역할을 담당하고 있다. 그러나, 건설 산업은 타 산업에 비하여 고위험 산업으로, 매년 많은 사고와 재해가 발생하고 있다. 노동부 중대산업재해감독과에 따르면 2022 년 재해조사 대상 사망사고 발생 현황 발표 결과, 건설 사고 사망자는 341 명으로, 전체 산업재해 사망사고자의 53%를 차지하고 있다. 최근 사회 변화와 다양한 경기 변동, 물가 상승에 따라 건설 공사 비용 절감을 위한 안정성 결여, 시공 품질 관리의 어려움, 근로자 안전 의식 부족 등의 문제가 심화되고 있다. 이에 따라, 건설 현장의 근본적인 안전문화의 정착과 함께, 첨단 ICT 기술을 활용한 지능형 건설 안전관리 시스템의 구축이 필요한다. 그리고, 건설안전관리를 위한 스마트 건설 안전관리통합관제시스템(SCMS)의 기능과 적용 범위를 더욱 확대함으로써 건설 현장의 안전사고 예방을 개선할 수 있을 것으로 기대된다. 이를 위해 지속적인 다양한 연구와 데이터 수집과 분석 등 기술적인 연구와 함께 법과 제도에 대한 개선 논의가 필요하다.

Objective : This study was performed to estimate the effects of OMC-2010 extract on cytokine production in mouse spleen cells. Methods : Mouse spleen cells were pre-treated with ethanol and water extract of OMC-2010 for 1 h, then stimulated with lipopolysaccharide (LPS, 1 ${\mu}g/ml$) for 48 h. Then the cells were harvested for real-time reverse transcription polymerase chain reaction to detect cytokines. Results : OMC-2010 ethanol extract significantly inhibited the LPS-induced interleukin (IL)-1beta, tumor necrosis factor (TNF)-alpha and IL-5 mRNA expressions, but not shown such changes in IL-6, IL-4, IL-13. OMC-2010 water extract significantly inhibited the LPS-induced TNF-alpha, and IL-5 mRNA expressions, but not shown such changes in IL-1beta, IL-6, IL-4, IL-13. Conclusions : Theses results could suggest that both ethanol and water OMC-2010 extract could inhibit the TNF-alpha and IL-5 mRNA expression.
