  • 여성에 대한 태도가 양가적인 속성(적대적인 태도와 온정적인 태도)을 지니는 것처럼, 남성에 대한 태도도 양가적인 속성을 보이는 것으로 알려져 있다. 최근 한국 사회에서 여성혐오대 남성혐오로 인한 성별 갈등이 심화되고 있지만, 대부분의 국내 연구들은 여성에 대한 태도에만 초점을 맞추고 있어, 남성에 대한 양가적 태도를 측정하는 국내 척도가 부재한 실정이다. 이에, 본 연구에서는 미국에서 개발되어 사용되고 있는 '남성에 대한 양가적 태도 척도'(The Ambivalence toward Men Inventory: AMI)를 한국어로 번안 및 타당화하였다. 이를 위해, 연구 표본 1(대학생 183명), 연구 표본 2(대학생 300명), 연구 표본 3(성인 317명)을 대상으로 탐색적 및 확인적 요인 분석을 실시하였고, 그 결과, 2개의 하위요인(남성에 대한 적대적인 태도, 남성에 대한 온정적인 태도), 16문항이 적절한 것으로 나타났다. 또한 수렴타당도와 준거타당도를 확인한 결과, 한국어판 남성에 대한 양가적 태도 척도(The Korean Version of the Ambivalence toward Men Inventory: K-AMI)는 한국인에게 사용하기에 타당한 도구로 확인되었다. K-AMI의 내적합치도도 .830~.917로 양호한 것으로 나타났다.

  • A nuclear power plant (NPP) piping is designed against low-frequency earthquakes. However, earthquakes that can occur at NPP sites in the eastern part of the United States, northern Europe, and Korea are high-frequency earthquakes. Therefore, this study conducts bi-directional shaking table tests on actual-scale NPP piping and studies the response characteristics of low- and high-frequency earthquake motions. Such response characteristics are analyzed by comparing several responses that occur in the piping. Also, based on the test results, a piping numerical analysis model is developed and validated. The piping seismic performance under high-frequency earthquakes is derived. Consequently, the high-frequency excitation caused a large amplification in the measured peak acceleration responses compared to the low-frequency excitation. Conversely, concerning relative displacements, strains, and normal stresses, low-frequency excitation responses were larger than high-frequency excitation responses. Main peak relative displacements and peak normal stresses were 60%-69% and 24%-49% smaller in the high-frequency earthquake response than the low-frequency earthquake response. This phenomenon was noticeable when the earthquake motion intensity was large. The piping numerical model simulated the main natural frequencies and relative displacement responses well. Finally, for the stress limit state, the seismic performance for high-frequency earthquakes was about 2.7 times greater than for low-frequency earthquakes.

  • 우리나라는 종전국이 아닌, 휴전국으로 그 시기는 약, 70여 년이 흐르고 있는 상황이며 이러한 특수성을 지닌 상황 속에서 우리나라의 보훈제도는 타 국가와 비교하여도 '보훈제도'가 미흡한 실정이다. 또한, 우리나라의 보훈정책은 보훈 선진국(미국·캐나다·호주·프랑스·독일)에 비해 보훈대상자들에 대한 '보훈예우' 제도가 미흡한 실정이며 그 중, 대표적 사례가 '참전군인·제대군인 지원제도'로 뽑을 수 있다. 따라서 본 연구의 비교 대상이 되는 보훈 선진국(미국·캐나다·호주·프랑스·독일)의 주요 보훈정책 제도 분석을 통해 정책적 함의를 도출한 결과 '보훈관련 주요 기념일을 확대'해야 할 것이며, '보훈선양'에 대한 대국민 인식 교육 도입이 필요한 것으로 정책적 대안을 제시하였으며 결국, 전·후 세대에게 분단의 아픔 및 상처를 올바르게 인식시켜 선진국형 보훈제도의 초석을 다져야 할 것이다.

  • We attempted to provide an overview of the laws and current state of the 3D printing industry in South Korea and around the world, using the annual industry surveys and the Wohler report. Additionally, we reviewed articles relating to the potential exposure to hazards associated with 3D printing using metal materials. In South Korea, there were 406 3D printing-related businesses, employing 2,365 workers, and the market size was estimated at 455.9 billion won in 2021. Globally, the average growth rate of the 3D printing industry market over the past 10 years was 27.4%, and the market size was estimated at $11.8 billion in 2019. The United States had the highest cumulative installation ratio of industrial 3D printers, followed by China, Japan, Germany, and South Korea. A total of 6,168 patents related to 3D printing were registered in the US between 2010 and 2019. Harmful factors during metal 3D printing was mainly evaluated in the powder bed fusion and direct energy deposition printing types, and there is a case of material extrusion type with metal additive filaments. The number, mass, size distribution, and chemical composition of particles were mainly evaluated. Particle concentration increases during the opening of the chamber or post-processing. However, operating the 3D printer in a ventilated chamber can reduce particle concentration to the background level. In order to have a safe and healthy environment for 3D printing, it is necessary to accumulate and apply knowledge through various studies.

  • 자료동화(data assimilation) 기법은 관측 자료와 예측 모형의 정보를 동시에 활용, 모형의 상태량(state variables)이나 매개변수(model parameters)를 실시간으로 업데이트하는 Bayesian 필터링 이론에 근거한 방법으로, 최근 이를 활용한 수문 모의 정확도 향상 기술이 빠르게 발전하고 있다. 본 연구에서는 앙상블 자료동화의 정확성을 향상시키기 위한 세부 방법인 along-the-stream localization과 inflation 기법의 분포형 수문 모형에 대한 적용성을 대규모 지역 단위(regional-scale) 모의를 통해 검토한다. 분포형 수문모형과 자료동화 framework로는 WRF-Hydro(Weather Research and Forecasting Model Hydrological Modeling System)와 DART(Data Assimilation Research Testbed)를 각각 적용한다. WRF-Hydro는 미국의 전 대륙지역(CONUS; continental United States)에 대한 수문 모델링 framework인 National Water Model의 핵심엔진이고, DART는 미국 National Center for Atmospheric Research(NCAR) 연구소에서 개발한 범용 자료동화 도구이다. 본 연구에서는 지표수 수문모형의 자료동화를 위해 개발된 기법인 along-the-stream localization과 inflation 기법이 하도 추적에 미치는 영향을 분석한다. along-the stream localization 기법은 공간적 근접도 외에 하도의 수문학적 연관관계를 고려하는 localization 기법으로, 상대적으로 수문학적 상관도가 떨어지는 하도에 대한 과도한 자료동화를 줄여줄 수 있다. inflation 기법은 앙상블의 다양성을 증가시키는 기법으로, 칼만 필터(Kalman filter)에 의한 업데이트의 이전이나 이후 적용하여 앙상블 예측의 정확도를 추가적으로 향상시킬 수 있다. 본 고에서는 앙상블 자료동화 기법을 지표수 수문 모의에 적용할 경우 남아 있는 난제와 적용 가능한 방법에 대해 중점적으로 논의한다.

  • A prerequisite for a lasting ceasefire is the emergence of a prevailing view in Moscow and Kyiv that the fighting has reached a hurting stalemate. In sum, they both lose more through continuing warfare than by a ceasefire. This study applies social identity dynamics of nationalism to this escalatory conflict. It generates findings that imply that China as a third-party great power intervening mediator can potentially play a pivotal role. Shifting the respective prevailing views in Moscow and Kyiv of their interaction from a zero-sum foundation requires proffering powerful economic and political third-party incentives. Effective inducement would facilitate national defense, development and prestige for Moscow as well as Kyiv. China arguably has the underutilized potential power capabilities necessary to alter the respective prevailing views of strategic relationships among the great powers within Moscow, Brussels and Washington. A prerequisite for success in striving effectively towards this strategic goal is cooperation with the Beijing despite skepticism from Washington. This study utilizes a process tracing methodological approach. It highlights that the foundations of the Russo-Ukraine war lie in the institutionalization within Euro-Atlantic integration of the Cold War assumption that the USSR was an imperialist revisionist actor. Russia is the USSR's successor state. Moscow's prevailing view is that Russian national self-determination was unjustly circumscribed in the multinational Soviet totalitarian Communist system. The Euro-Atlantic community is perceived as a neocolonial imperial threat by allying with post-1991 Ukrainian nationalism at Russia's expense. The study finds that acknowledging Eurasian regional multipolarity is necessary, if not sufficient, to coopt Beijing into a global political stabilization strategy. It functionally aims to promote international balancing to lessen potentials for horizontal as well as vertical escalation of the Russo-Ukrainian conflict.

  • Objectives: This study aimed to systematically review thread-embedding treatment studies for depression, anxiety, and dementia and examine the effectiveness and safety of thread-embedding treatment. Methods: Ten domestic and international search databases were used for study selection, including CNKI, PubMed, CENTRAL, EMBASE, CINAHL, AMED, PsycArticles, RISS, OASIS, and KCI. We included studies that presented diagnostic or appropriate criteria for depression, anxiety, and dementia, and randomized control studies using thread-embedding therapy. We searched papers published until October 10, 2023. Results: Twenty-one studies were selected, of which 11 studies were conducted on depression, nine on dementia, and one on anxiety disorders. The most commonly used acupoint for depression was Gansu (BL18), whereas zusanli (ST36) and fenglong (ST40) were used for dementia. The most commonly used type of thread was 1-0 United States pharmacopeia (USP) and 1 cm for depression and 2-0 USP and 1 cm for dementia. The treatment period for most of the studies was once every 2 weeks and for 8 weeks. Among the included studies, 17 showed significant improvements in depression scales, such as Hamilton depression rating scale and Self rating depression scale, activities of daily living scales, and cognitive function scales, such as Hasegawa dementia scale and Mini-mental state examination. Six studies reported adverse events, and no studies reported significant adverse events. Two studies reported follow-ups. Conclusions: This study presents limited evidence for the effectiveness and safety of thread-embedding therapy for depression, anxiety, and dementia. Well-designed studies are needed to review the clinical efficacy and safety of thread-embedding therapy in the future.
