Purpose: The purpose of this study is to derive major policies that domestic small and medium-sized manufacturing companies should consider to maximize productivity and quality improvement by utilizing manufacturing data and AI, and to find priorities and implications. Methods: In this study, domestic and international issues and literature review by country were conducted to derive major considerations such as manufacturing AI technology, manufacturing AI talent, manufacturing AI data and manufacturing AI ecosystem. Additionally, the questionnaire survey targeting 46 experts of manufacturing data and AI industry were conducted. Finally, the major considerations and detailed factors importance were derived by applying the Analytic Hierarchy Process (AHP). Results: As a result of the study, it was found that 'manufacturing AI technology', 'manufacturing AI talent', 'manufacturing AI data', and 'manufacturing AI ecosystem' exist as key considerations for domestic manufacturing AI. After empirical analysis, the importance of the four key considerations was found to be 'manufacturing AI ecosystem (0.272)', 'manufacturing AI data (0.265)', 'manufacturing AI technology (0.233)', and 'manufacturing AI talent (0.230)'. The importance of the derived four viewpoints is maintained at a similar level. In addition, looking at the detailed variables with the highest importance for each of the four perspectives, 'Best Practice', 'manufacturing data quality management regime, 'manufacturing data collection infrastructure', and 'manufacturing AI manpower level of solution providers' were found. Conclusion: For the sustainable growth of the domestic manufacturing AI ecosystem, it should be possible to develop and promote manufacturing AI policies in a balanced way by considering all four derived viewpoints. This paper is expected to be used as an effective guideline when developing policies for upgrading manufacturing through domestic manufacturing data and AI in the future.

진해만은 우리나라 남해 연안의 주요 어장으로서, 여전히 전체 수산생산량에서 적지 않은 기여를 창출하고 있다. 그러나, 수십 년간 산업개발과 고수온과 같은 환경변화로 인하여 진해만의 해양생태계는 과거와 달라지고 있다. 본 연구는 2005년부터 2022년까지 진해만 연안 5개 시군구의 수산생산량, 폐기량, 평균영양단계 및 어업균형지수를 분석하였으며, ARIMA 모델을 이용하여 2027년까지 단기적인 변동 추세를 함께 관찰하였다. 그 결과, 고성지역은 2027년까지 지속적으로 수산생산량이 감소할 것으로 예측되었다. 통영지역은 이매패류의 부산물 처리가 필요한 것으로 평가된다. 해양생태계 지표의 경우, 통영지역에서는 대형 어류 생산 비중이 회복되고, 어업균형지수가 0 이상을 나타내어 해양생태계 구조가 안정적인 것으로 나타났다. 마지막으로 IPCC의 기후변화 시나리오에 따라 2060년까지 진해만의 부어성 어종 6종의 생산량 변동 추이를 비교하였으며, 2020년대 초반 2만 ton 부근까지 감소했던 생산량은 2020년대와 2040년대에 4만 ton 부근 가까이 회복한 후, 2060년까지 점진적인 감소 경향을 나타내는 것으로 예측되었다.

서울온수산업단지는 준공한 지 50년이 넘은 노후산업단지로, 산업단지 기반시설과 공장 건축물의 노후화가 진행중이다. 그럼에도 불구하고, 현재 서울온수산업단지에는 기계 산업 중심의 도시산업 집적이 발생하고 있다. 이 연구의 목적은 노후산업단지의 물리적 시설 노후화와 산업 집적 특성을 종합적으로 분석하여 서울온수산업단지의 정체성을 도출하는 데에 있다. 연구 결과, 서울온수산업단지는 수도권에 집중된 거래 네트워크, 소필지화로 인한 영세기업의 입주, 소음 유발 공정의 허용, 고숙련 기술자 확보 용이성에 따라 도시산업 집적이 강화되고 있다. 그러나 이 집적은 산업단지 생산기능의 약화, 입주기업의 제한된 혁신성, 수도권 기계 산업경쟁력 약화에 따른 비혁신적 특성이 공존하는 것으로 나타났다. 이를 종합하면 서울온수산업단지의 정체성은 '비혁신형 도시산업 집적지'로, 수도권 중심의 기계 산업 네트워크에 기반한 비혁신적 집적이 발생하고 있는 노후산업단지이다.

Although the industrial society gained people with material wealth, they were panic-stricken, felt in lack of everything, not to mention how fast the environment was destroyed. In the midst of this social flow, more and more people who became aware of the problems of the industrial society began to crave happy and beautiful lives through the combination of mental and physical health. This resulted in a new lifestyle called 'well-being'. Lohas, which has become a prominent figure through deep thoughts on social well-being is beyond the persuation of an individual's health and quality of life. Not only does Lohas propose a lifestyle for the mental and physical health of an individual, it also proposes sustainable consumption without hurting the world or the environment. The appearance of the Lohas provided an opportunity not only for people to look in a different aspect on the problems of pollution and ecosystem but to develop and design different products accordingly. Through furniture designs with the idea of lifestyles of health and sustainability applied, this thesis analyses how the main concept of the 3R-Recycle, Reuse, and Reduce is being applied and put to use productively in furniture design.

Industrialization and urbanization are modern need and trends. Such trends affect the natural ecosystem of rivers. Indian rivers face such problems in a high ratio. The aim of this study is to investigate the cause and amount of pollution in a tributary river Krishni. Pre-monsoon sampling of Krishni river water was performed as per APHA standard. Water samples were collected from different sites of Krishni river. Physiochemical parameters as well as trace elements concentrations have been analysed and results were compared with BIS-2012, WHO-2017 and EPA-2001 recommendations. The presence of high BOD, COD, TDS and others physiochemical parameters along with heavy metals reveals that tributary is highly polluted owing to industrial and domestic discharge either directly or through drains. High values of these parameters are harmful for the ecological health of the river because it makes survival of aquatic flora and fauna at risk. On the basis of the results obtained by the present study, it was concluded that level of the pollution in river Krishni is at alarming phase, where if strong action for the rejuvenation of river not takes place, river becomes a dead pool.
