A three-dimensional physical part can be fabricated from a three-dimensional digital model in a layer-wise manner via additive manufacturing (AM) technology, which is different from the conventional subtractive manufacturing technology. Numerous studies have been conducted to take advantage of the AM opportunities to penetrate bespoke custom product markets, functional engineering part markets, volatile low-volume markets, and spare part markets. Nevertheless, materials issues, machines issues, product issues, and qualification/certification issues still prevent the AM technology from being extensively adopted in industries. The present study briefly reviews the standard classification, technological structures, industrial applications, technological advances, and qualification/certification activities of the AM technology. The economics, productivity, quality, and reliability of the AM technology should be further improved to pass through the technology adoption lifecycle of innovation technology. The AM technology is continuously evolving through the introduction of PM materials, hybridization of AM and conventional manufacturing technologies, adoption of process diagnostics and control systems, and enhanced standardization of the whole lifecycle qualification and certification methodology.

오지원(Ji-Won OH),신서원(Seo-Won SHIN) 한국상담심리교육복지학회 2024 상담심리교육복지 Vol.11 No.2

이 연구는 ADHD 아동의 부모상담에서 비효과적인 상담과정과 그 과정에 영향을 미치는 요인을밝혀내기 위한 질적 연구이다. ADHD 아동 및 부모 상담경험이 있는 상담자 13명을 대상으로 반구조화된 인터뷰를 실시하였고, 근거이론 방법으로 자료를 분석하였다. 연구결과 9개의 상위범주와 20 개의 하위범주가 발견되었으며, 비효과적인 부모상담을 초래하는 요인으로는 부모의 인지·정서적어려움, 양육에 집중할 수 없는 가정환경, 낮은 사회적 지지 등이 확인되었다. 중심현상으로는 부모의 변화 동기 부족이 발견되었으며, 뒤이어 부모는 상담개입에 대한 부정적 반응과 부정적 상담관계를 형성하는 것으로 나타났다. 이를 중재하는 요인으로는 상담역량, 역전이 관리 능력, 상담실 환경이 발견되었다. 이러한 결과를 토대로, 비효과적인 부모상담 예방을 위한 방안들을 논의하였다. The purpose of this study is to explore ineffective counseling processes with ADHD children’s parents and related barriers. Thirteen counselors who had counseling experience with ADHD children and their parents were recruited. Semi-structured interviews were conducted and data were analyzed using a grounded theory approach. As a result, nine categories and 20 subcategories were identified. Parents’ cognitive or emotional difficulties, family conditions that cause poor parenting, and insufficient social support were found as causal or contextual conditions. Low motivation for changes was identified as a central phenomenon which, in turn, generated negative responses to counseling and poor counseling alliance. Counselors’ competence, counter-transference management, and counseling facility were identified as intervening conditions. Based on these findings, implications to prevent potentially harmful counseling were discussed.

근로 장애인의 근무환경이 직무만족에 미치는 영향 : 장애 유형에 따른 차이를 중심으로

오지원(Ji Won Oh),여영훈(Yeong Hun Yeo) 한국장애인복지학회 2021 한국장애인복지학 Vol.52 No.52

본 연구는 근로장애인의 직무환경이 직무만족에 미치는 영향을 검증하고, 장애유형에 따라 직무환경 영향력의 상이성을 파악하는 것을 목적으로 하였다. 직무환경은 물리적 및 제도적 직무환경으로 구분하였고, 장애유형은 장애인복지법의 장애유형 중분류를 바탕으로 근로역량 차이를 고려하여 신체외부장애, 감각장애, 정신적 장애, 신체내부장애로 분류하였다. 장애인고용패널 2차 웨이브 3차 조사의 근로장애인 1,395명을 대상으로, 전체 근로장애인 및 각 장애유형에 따라 각각의 위계적 회귀분석을 실시하여, 모델설명력 변화 및 근무환경 회귀계수의 유의미 차이를 비교 검증하였다. 첫째, 장애유형에 따라 물리적 근무환경 및 직무만족의 차이는 나타나지 않았으나 제도적 근무환경의 경우 정신적 장애가 타 장애유형과 비교하여 낮은 것으로 나타났다. 둘째, 전체 근로장애인의 경우, 물리적 근무환경과 제도적 근무환경 모두 유의미하게 직무만족에 정적(+)인 영향을 미쳤다. 셋째, 물리적 근무환경은 모든 장애유형에 유의미한 직무만족에 대한 영향력이 나타났고, 제도적 근무환경은 신체외부장애만 유의미한 결과를 보였다. 이러한 결과는 직무만족에 있어 근무환경의 중요성과 함께, 각 장애유형에 따라 물질적. 제도적 근무환경의 영향력이 상이할 수 있음을 보여준다. 즉 각 장애유형 특성을 보다 세밀히 반영한 직무환경조성과 지원제도 확충 및 장애인 고용 정책이 필요함을 시사한다. The purpose of this study were to verify the effects of working environment on job satisfaction of the disabled workers. to identify the differences in the influence of the working environment according to the type of disability. This study measured working environment by physical and institutional environment. and the disability grouped into physical external disorder. sensory disorder. mental disorder. and internal disorder. Based on the 1.395 workers with disabilities of the Panel Survey of Employment for the Disabled(PSED) Wave 3. this study employed a series of hierarchical regression analysis to estimate the difference of the influence of working environment by the disability types with the comparison of R-squared changes and regression estimates. First. working environment for the disabled is dangerous. job satisfaction is normal. and institutional working environment has significant difference by type of disability. Second. in all types of disability. the most significant effect of safe and pleasant working environment on job satisfaction was found. Third. different types of work were shown by types of disabilities. and this form was related to variables that had a significant effect on job satisfaction. Fourth. the influence of physical working environment which commonly affects by type of disability was the most powerful. and institutional working environment showed significant results only for physical external disability. The factors that affect the job satisfaction of the working disabled by comparing the effects of the working environment of the working disabled with the types of disabilities were confirmed. The policy implications of the working environment of the working disabled should be created to create an environment that reflects the characteristics of the types of disabilities so that both the non-disabled and the disabled can work in a safe working environment.

파우더와 오일의 배합 비율이 탈크 프리 프레스드 파우더 제형의 안정성에 미치는 영향에 관한 연구

오지원 ( Ji Won Oh ),김현지 ( Hyun Jee Kim ),곽병문 ( Byeong Mun Kwak ),조한태 ( Hantae Jo ),이미기 ( Mi-gi Lee ),빈범호 ( Bum-ho Bin ) 대한화장품학회 2021 대한화장품학회지 Vol.47 No.1

프레스드 파우더의 주요 안정성 요인으로 경도와 낙하 안정도가 있다. 일반적으로 탈크가 포함된 프레스드 파우더의 경우 경도와 낙하 안정도를 고르게 충족시키며 사용감도 우수하지만 최근 탈크의 석면 이슈로 인해 대체를 원하는 고객들이 늘고 있다. 따라서 안정성을 유지하면서 사용감도 떨어지지 않는 탈크 프리 프레스드파우더 제형의 개발이 시급하다. 본 연구에서는 탈크 프리 프레스드 파우더를 만들기 위한 최적의 원료 배합비율을 찾기 위한 실험을 진행하였다. 파우더에 주로 사용되는 원료들의 특성을 확인하고 비율을 변화시켜 실험하여 명도와 경도를 측정하고 낙하 시험을 실시하였다. 천연 마이카 함량이 합성 마이카보다 많거나, 코팅된 실리카 대신 논 코팅 실리카를 사용할 경우 탈크가 포함된 내용물보다 경도와 낙하 안정도는 낮지만 명도는 유사하였다. 반대로 합성 마이카 함량이 천연 마이카 함량과 동일하거나 높을 경우, 코팅된 실리카 함량이 논코팅 실리카 함량과 동일하거나 높은 경우에 탈크가 포함된 내용물의 경도, 낙하 안정도와는 유사하였으나 명도는 낮게 측정되었다. 탈크가 포함된 내용물보다 경도는 높지만 낙하 안정성은 떨어지는 현상도 발견하여 경도와 낙하 안정성의 상관관계에 대해서는 추가적인 연구가 필요할 것으로 생각된다. The main stability factors of the pressed powder include hardness and drop stability. In general, for pressed powder with talc, the hardness and drop stability are evenly met and the skin texture is excellent. Recently, more than ever customers are looking for a replacement due to asbestos issue of talc. Therefore, it is urgent to develop a pressed powder formulation without talc that maintains stability and does not lose its sense of use. In this study, experiments were conducted to find the optimal ingredients mixing ratio to make talc-free pressed powder. The characteristics of raw materials used mainly in powder were checked and the ratio was changed, and the lightness and hardness were measured and drop test was conducted. If the natural mica ratio was higher than the synthetic mica or non-coated silica was used instead of the coated silica, the hardness and drop stability were lower than the content containing talc, but the lightness was similar. Conversely, if the synthetic mica ratio was equal to or higher than the natural mica ratio and the coated silica ratio was equal to or higher than the non-coated silica ratio, the hardness and drop stability of the content containing talc were similar, but the lightness was low. It was found that the hardness was higher than the content containing talc, but the drop stability was lower. Therefore, further study of the correlation between hardness and fall stability is also thought to be necessary.
