박한빛,이진균,구예진 한국고분자학회 2021 한국고분자학회 학술대회 연구논문 초록집 Vol.46 No.1

Extreme ultraviolet light at 13.5 nm can implement finer circuit patterns than ArF (193 nm) light sources, but the number of photons absorbed per unit area is only 1/14, which deteriorates the characteristics of the resist. We synthesized a molecular material having a cyclic acetal structure using three benzaldehyde derivatives based on the vascular contrast agent molecule for computed tomography (CT) containing a lot of iodine with high absorbance. The synthesized material has excellent solubility in a resist coating solvent and is changed to a water-soluble structure through an acid-catalyzed decomposition reaction. the synthesized molecular iodide material is mixed with a resist polymer and Photoacid generator (PAG) and formed into a thin film. under extreme ultraviolet patterning conditions, The Line-edge roughness (LER) and sensitivity have obtained the patterning of improved result than the comparison group that does not contain this.

성인 여성의 내현적 자기애가 신체화에 미치는 효과: 신체귀인으로 조절된 정서표현억제의 매개효과

박한빛,이창현 한국여성심리학회 2024 한국심리학회지 여성 Vol.29 No.3

신체화는 남성보다 여성들에게 빈번하게 나타나며, 한국 여성들은 신체화 경향성이 더욱 높다고 알려져 있다. 신체화와 관련이 있는 변인으로 내현적 자기애가 보고되었지만 내현적 자기애와 신체화 사이에 어떠한 심리적 과정을 거치는지에 관한 연구는 매우 부족한 상황이다. 따라서 본 연구에서는 성인 여성의 내현적 자기애와 신체화의 관계를 정서표현억제가 매개하는지 살펴보고, 신체귀인이 이러한 매개효과를 조절하는지를 검증하고자 하였다. 이를 위해 20세에서 59세 사이 성인여성 205명을 대상으로 온라인 설문을 통해 자료를 수집하여, 조절된 매개효과의 유의성을 검증하였다. 첫째, 내현적 자기애, 정서표현억제, 신체귀인, 신체화 사이에 유의한 상관이 있었다. 둘째, 내현적 자기애와 신체화의 관계에서 정서표현억제의 매개효과가 유의하였다. 셋째, 정서표현억제와 신체화의 관계를 신체귀인이 조절하였다. 넷째, 내현적 자기애와 신체화의 관계에 대한 정서표현억제의 매개효과가 신체귀인에 의해 조절되는 것으로 나타났다. 본 연구는 내현적 자기애 수준이 높은 사람에게 신체화가 발생하는 경로와 개인이 지닌 신체귀인 수준이 높아질수록 정서표현억제가 신체화에 미치는 효과가 증가되는 것을 밝혔을 뿐만 아니라 내현적 자기애가 정서표현억제를 경유하여 신체화로 이어지는 경로가 개인의 신체귀인 수준에 의존함을 밝혔다. 이를 상담 및 심리치료 장면에서 내현적 자기애 수준이 높은 성인 여성 내담자들에 대한 보다 깊은 이해와 치료적 개입에 도움이 되는 시사점을 제시했다는데 본 연구의 의의가 있다. Somatization is more frequent in women than in men, and Korean women are known to be more prone to somatization. Although covert narcissism has been reported as a variable related to somatization, there is a dearth of research on the psychological processes between covert narcissism and somatization. The purpose of this study was to examine the mediating effect of suppression of emotional expression relationship between covert narcissism and somatization in adult women, and the moderated mediating effect of body attribution in this path. For this purpose, 240 people aged 20 to 59 were measured through self-report surveys for covert narcissism, suppression of emotional expression, body attribution, and somatization. First, a significant correlation was found in all major variables. Second, the mediating effect of suppression of emotional expression was significant in the relationship between covert narcissism and somatization. Third, body attribution moderated the relationship between suppression of emotional expression and somatization. Fourth, it was found that the mediating effect of suppression of emotional expression on the relationship between covert narcissism and somatization was moderated by body attribution. In other words, those with high body attribution are more likely to experience somatization through suppression of emotional expression, even if they experience covert narcissism. This study is meaningful in that it presents implications that are helpful for understanding and intervention of adult Female clients with a high level of covert narcissism in psychotherapy.

복합적인 의사소통 요구를 지닌 아동 부모의 AAC 포기 경험과 지원 요구

박한빛,이주연,박현주 한국보완대체의사소통학회 2020 보완대체의사소통연구 Vol.8 No.2

Background and Objectives: Parents are one of the most crucial stakeholders in interventions involving children. In this study, we examined the experiences and demands of parents of children with complex communication needs who abandoned augmentative and alternative communication (AAC). Method: We conducted face- to-face individual in-depth interviews with six parents using a semi-structured questionnaire. The interviews were recorded and then transcribed to organize and categorize the data using the constant comparative method. Results: Participants’ experiences with AAC abandonment were classified as: (a) From Hope to Disappointment, (b) Lack of Practical Support, and (c) Difficulty of Information Acquisition. Their demands of AAC were classified as: (a) Adjustment of Balance Between Promotion and Education, (b) Establishment of Strong Educational Systems for the Use of AAC, and (c) AAC as a True Means of Communication. Conclusion: The study showed that, although parents of children with complex communication needs were aware of AAC, they did not receive corresponding support for implementing it. Practical challenges impeding AAC utilization and means for supporting and facilitating the use of AAC were discussed. 배경 및 목적: 아동 대상의 중재에서 부모는 가장 중요한 이해당사자 중 하나이다. 본 연구에서는 복합적인 의사소통 요구를 지닌 아동 부모의 보완대체의사소통(AAC) 포기 경험과 지원 요구를 알아보고자 하였다. 방법: 복합적인 의사소통 요구를 지닌 자녀를 위해 AAC를 시도하였으나 현재는 AAC 사용을 포기한 부모 6명을 대상으로 반구조화된 질문지를 사용하여 면대면 개별 심층면담을 진행하였다. 면담 내용은 녹음 후 전사하여 자료를 구성하고 연속적 비교법에 따라 주제를 도출하였다. 결과: 연구 참여자의 AAC 포기 경험은 ‘희망에서 실망으로’, ‘실제적인 지원 부족’, ‘정보 습득의 난관’ 이라는 3개의 주제로 요약되었고, AAC에 대한 지원 요구는 ‘홍보와 교육의 균형 맞추기’, ‘견고한 AAC 교육시스템 구축’, ‘진정한 소통 수단으로서의 AAC’라는 3개의 주제로 요약되었다. 논의 및 결론: 본 연구 결과는 복합적인 의사소통 요구를 지닌 아동 부모의 AAC에 대한 인식에 비해 AAC이행을 위한 실제적인 지원이 부족함을 보여주었다. 본 연구 결과를 토대로 AAC 사용을 저해하는 현실적인 어려움과 AAC 사용 촉진을 위한 지원 방안을 논의하였다.

박한빛(Han-Vit Park),윤린(Rin Yun),김영득(Young Deug Kim),이성재(Sung-Jae Lee),최석동(Seok Dong Choi) 대한기계학회 2010 대한기계학회 춘추학술대회 Vol.2010 No.11

The usage of the CO₂ water heater has been increased due to its environmental friendly characteristics and the higher water temperature compared to that of conventional refrigerant. Also, it has lower running cost and higher system efficiency compared to the gas-fired water heater. In this study, the basic design for the Co2 water heater of which the compressor power consumption of 10HP is conducted. The CO2 water heater is composed of a compressor, a gas cooler, an expansion device, an internal heat exchanger(IHX), and a water reservoir tank .The mass flow rate, the discharge temperature and the pressure were calculated by using the efficiency model of the compressor. The rotation speed and the sweep volume for the compressor is obtained from the Dorin semi-hermetic 8㎾ compressor. The gas cooler and the IHX were designed by the ε-NTU method, which is applied to the finite volume. The capacity of them was calculated through the CO2 mass flow rate and the assumed inlet and outlet temperature. The evaporator was designed by the EVAP-COND under the various outside temperatures.

Numerical modeling of CO₂ water heater was conducted prior to optimal design of medium and large sized CO₂ water heater, and the experimental test with small sized CO₂ water heater having heat capacity of 4 kW was completed to verify the present numerical model. The present model estimated the experimental data of COP(coefficient of performance), heating capacity, and the hot water outlet temperature within the range of 3% to 8% of mean deviation. As increase of EEV(electric expansion valve) opening area, decreasing of heating capacity and the hot water outlet temperature, and increasing of COP were found in both experimental and numerical investigation.

중형 이산화탄소 급탕기의 최적 설계

박한빛(Hanvit Park),윤린(Rin Yun),김영득(Young Deug Kim) 대한설비공학회 2013 설비공학 논문집 Vol.25 No.4

Middle-sized CO₂ water heater having compressor power of 7.45 kW was designed, and its performances were experimentally tested. Besides, optimum design of the CO₂ water heater was conducted by cycle simulation. When ambient temperature of 7℃ and hot water outlet temperature of 80℃ the CO₂ water heater showed the COP of 3.2. As hot water temperature increased the COP is getting decreased due to significant increase of compressor power consumption compared to increasing rate of heating capacity. When ambient temperature increased from -3℃ to 12℃ the COP increased by 30%. The optimum components design of a gas cooler, an internal heat exchanger, and an evaporator were conducted, and the experimental correlation between amount of EEV opening and ambient temperature, and hot water temperature was suggested.
