배경 및 목적: 본 연구는 발성훈련에 대한 언어치료 환자의 치료 동기와 참여를 향상시키기 위한 기능성 게임에 대한 요구사항과 개발방향을 파악하기 위해 수행되었다. 방법: 문헌조사, 이해당사자 요구조사, 기존 3가지 발성훈련 게임(Visi Pitch, Dr. Speech, Vox System)의 벤치마킹 분석이 수행되었다. 결과: 문헌조사를 통해 13가지 게임 사용자 경험 척도들(유용성, 서사성, 몰입, 즐거움, 창의성, 오디오 심미성, 개인적 충족감, 사회적 연결성, 시각적 심미성, 정확성, 개인 맞춤형 분석, 게임 분석, 치료 연속성)이 파악되었다. 사용자 경험 척도들 중 기존 언어치료게임에서 일반적으로 미흡한 속성들로는 창의성(평균 만족도=2.5-4.3; Likert 7점 척도 사용), 사회적 연결성(2.4-4.4), 치료 연속성(1.7-4.7), 그리고 개인 맞춤형(2.5-5.0)이 파악되었다. 논의 및 결론: 본 연구의 사용자 경험 척도들은 발성훈련 기능성 게임을 평가하는 데 유용하게 활용될 수 있으며, 기존의 게임들이 상대적으로 미흡한 사용성 경험 척도를 보완하는 새로운 기능성 게임 개발이 필요하다. Objectives: The present study intended to identify the needs and development directions of a serious vocal training game for better motivation and commitment of patients with voice disorder to voice therapy. Methods: A literature review, a survey of stakeholders’ needs, and a benchmarking analysis of three vocal training games (Visi Pitch, Dr. Speech, and Vox System) was conducted. Results: From the literature review, thirteen game user experience scales (usability, narratives, play engrossment, enjoyment, creative freedom, audio aesthetics, personal gratification, social connectivity, visual aesthetics, accuracy, customization, game analytics, and therapy continuity) were identified for vocal training games and then applied to evaluation of the existing games. From the user experience scales, features not commonly implemented in the existing games include creative freedom (average satisfaction score, 2.5 to 4.3 out of 7), social connectivity (2.4 to 4.4), therapy continuity (1.7 to 4.7), and customization (2.5 to 5.0). Conclusion: The user experience scales would be of use to assess vocal training games, and new serious games need to be developed to complement the existing games in terms of the four scales found relatively lacking.

A kinetic study on the addition reaction of carbon dioxide and phenyl glycidyl ether(PGE) was investigated. NaI and polyethylene glycol(PEG-4000) was used as mixed catalyst, and the reaction was carried out using autoclave. A method to calculate rate constant and Henry`s law constant of CO₂ was proposed by measuring CO₂ pressure. The reaction was first order to the concentration of PGE and CO₂ respectively. The reaction rate constant(k) was 0.334 ℓ/㏖·min and Henry`s constant(H´) was 7.4×10^(-4) ㏖/ℓ·㎪.

In this experimental study, the air cooling radial shape heat exchanger which influences on the COP and the cooling capacity by heat and mass transfer rate in the adsorbent bed was designed and applied to test its performance for adsorption heat pump(AHP). Zeolite-water was used for the adsorbent-adsorbat pair. As a result, the cooling COP and a cycle period of this adsorption heat pump are 0.28 and 2 hours, respectively, on the condition of none heat recovery from the adsorption reactor(absorber). The other results and recommendations are mainly related to improving the heat and mass transfer inside the absorber to reduce a cycle period.
상이동 촉매에 의한 Phenyl Glycidyl Ether 와 이산화탄소의 부가반응
박대원,문정열,양정규,박성훈,이진국 ( Dae Won Park,Jeong Yeol Moon,Jeong Gyu Yang,Sung Hoon Park,Jin Kook Lee ) 한국공업화학회 1996 공업화학 Vol.7 No.1
본 연구는 이산화탄소와 phenyl glycidyl ether(PGE)의 부가반응에 대하여 상이동 촉매의 특성을 고찰한 것이다. 4급 암모늄염 상이동 촉매의 경우 알킬기의 크기가 크고 짝이온의 친수성이 강할수록 좋은 촉매활성을 나타내었다. 폴리에틸렌글리콜과 crown ether도 NaI와 함께 사용한 결과 효율적인 촉매임을 알 수 있었다. 이산화탄소의 압력이 증가하면 용매인 NMP에 대한 CO₂의 용해도가 증가하여 PGE의 전화율이 증가하였다. 또한 상이동 촉매의 역할이 포함된 반응메카니즘을 제시하였다. This study is related to the investigation of the characteristics of phase transfer catalysts on the addition reaction of carbon dioxide and phenyl glycidyl ether(PGE). Quaternary ammonium salts showed a good conversion of PGE at 1atm of CO₂. Among the quaternary ammonium salts tested, the ones with higher alkyl chain length and with more hydrophilic counter anion showed higher catalytic activity. Polyethylene glycol and crown ether were also effective catalysts when they are used with NaI. High pressure of CO₂ increased the conversion of PGE by increasing solubility of CO₂ in NMP. A mechanism of the reaction involving the role of phase transfer catalyst was also proposed.

본 연구는 이산화탄소와 glycidyl vinyl ether(GVE)의 부가반응에 대하여 상이동 촉매의 특성을 고찰한 것이다. 4급 암모늄염 상이동 촉매의 경우 상압에서도 비교적 좋은 GVE 전화율을 나타내었고, 알킬기의 크기가 크고 짝음 이온의 친수성이 강할수록 촉매활성이 높았다. 폴리에틸렌글리콜이나 triethylamine을 NaI와 함께 사용한 결과 NaI보다 (2-oxo-1,3-dioxolane-4-yl)methyl vinyl ether(OVE)의 수율이 높았다. 그러나 크라운 에테르는 촉매활성을 감소시켰다. 한편 속도론적 고찰 결과 반응속도는 GVE의 농도에 대하여 유사 1차 반응으로 나타났으며, 상이동 촉매의 역할이 포함된 반응메카니즘도 함께 제시하였다. This study is related to the investigation of the characteristics of phase transfer catalysts on the addition reaction of carbon dioxide and glycidyl vinyl ether(GVE). Among the quaternary ammonium salts tested, the ones with the higher alkyl chain length and with the more hydrophilic counter anion showed higher catalytic activity. Mixed catalysts of (polyethylene glycols + NaI) and (triethylamine + NaI) showed higher yield of (2-oxo-l,3-dioxolane-4-yl)methyl vinyl ether(OVE) than NaI itself, but the catalyst activity decreased by addition of a crown ether. Kinetic studies showed that the reaction rate was pseudo-first order with respect to the concentration of GVE. A mechanism of the reaction involving the role of phase transfer catalysts was also proposed.
