배기가스에서 이산화탄소 분리를 위한 재료 및 공정에 대한 이론적 고찰
한상일,황규석,Han, Sang-Il,Hwang, Kyu-Suk 한국응용과학기술학회 2014 한국응용과학기술학회지 Vol.31 No.3
Carbon dioxide ($CO_2$) is a green-house gas which causes the global warming problems. Anthropogenic emissionspredominantly from the combustion of coal, oil, and natural gas in electricity generations are expected to increase continuously in the future, resulting in increased $CO_2$ concentration in the atmosphere. In this study, we investigated materials properties and process systems for $CO_2$ separation with an emphasis of the post-combustion process. 이산화탄소는 온실가스로써 대기 중에 축적되어 지구의 온도를 지속적으로 상승시킨다. 화석연료 기반의 전력 생산에서 발생되는 이산화탄소는 상당량을 차지하며, 향후 수십 년간 화석연료 의존도는 지속적으로 증가할 것으로 예상된다. 따라서 대기 중으로 배출되는 이산화탄소를 분리하는 기술개발은 매우 시급하다. 이산화탄소 분리 기술은 크게 전처리, 후처리, 순산소 연소 방식으로 나뉘며, 본 연구에서는 후처리 제거 공정을 중심으로 제올라이트, 활성탄, MOF 소재의 이산화탄소 분리 특성을 비교하고, 공정기술에 대해 분석하였다.

비기환(?氣丸)이 백혈병(白血病)과 임파종(淋巴腫) 환자(患者)에서 추출(抽出)한 암세포(癌細胞)에 미치는 항암효과(抗癌效果)
한상일,강병기,Han, Sang-Il,Kang, Byung-Ki 대한한방내과학회 1991 大韓韓方內科學會誌 Vol.12 No.2
Bigihwan which has been widely used in Oh-jug in oriental Medicine was investigated on its antitumor effect employing blood cancer cell lines. K 562 derived from human erytholeukemia, Raji from lymphoma and $MO_4$ from hlastogenic cancer were used in this study to see the analytical evaluation of Bigihwan' s antitumor effect using three different kinds of methods such as $^{3}H-thymidine$ up take assay. MTT assay and live cell counts by Trypan blue assay. The result obtained are as follows. 1. When higher than 10% Bigihwan was treated. inhibitory effect of tumor killing action was observed showing the increasing order of $MO_4$, K 562 and Raji(Fig. 3). 2. When 1 to 5% of Bigi-hwan was treated, 4 to 30% of tumor cell survival was observed according to various blood tumor cell lines suggesting that antitumor effect of Bigi-hwan was different as the characteristics of tumor cells showing 70 to 95% cell killing effent(Fig. 4). 3. Compared the survivals of cells by relative scales though the initial cpm was variable because of different cell growth rate. Raji was most effective being killed 95% by the treatment of 1% Bigihwan while Raji and K562 showed 93% by 5% Bigihwan.(Fig. 5) 4. The survival rate of Raji derived from Burkitt lymphoma was rather increased to 2.3 times when Bigihwan concentration was increased from 1 to 10% lmplying of refraining from over use of this anticancer drug. specially to lymphoma patients(Fig. 5). 5. Bigihwan was most effective to K 562 and then $MO_4$ showing 95% tumor cell death by using 1% of this anticancer drug while it was least effective to Raji showing only 68% of tumor cell death(Fig.7). 6. Judging from the all the analytical methods used in this study, through all different three tumor cell lines. Bigihwan was most effective to K 562 derived from human erythroleukemia.

축제참여의 추진요인과 유인요인에 관한 탐색적 연구 -안동국제탈춤패스티벌을 중심으로-
한상일 ( Han Sang Il ) 대한관광경영학회 2004 觀光硏究 Vol.18 No.3
This study was conducted to find the factors and the relationships involved in behavior of local festival participants. The purpose of this study as follows: First, it was to investigate push factors and pull factors in the context of local festival. Second, it was to find relationships between the push factors and pull factors. Third, it was to identify relationships of impacts between the push factors, the pull factors and intention to revisit and to recommend to others. According to results of this research, three push factors and six pull factors were reduced from a factor analysis. Several relationships were found between the push factors and pull factors. The results also shows that the push factors and pull factors significantly influence to the intention to revisit.

스마트폰 기반 뱅킹 서비스의 특성과 지속적 사용의도의 관계
한상일(Sang-Il Han) 한국산업경제학회 2013 산업경제연구 Vol.26 No.3
스마트폰의 확산에 힘입어 스마트폰 기반 뱅킹 서비스 이용자가 꾸준히 증가하고 있지만 이용자들이 얼마나 효용성 있게 수용하고 이용하는지의 여부는 아직 미지수이기 때문에, 이용자들이 서비스를 어떻게 받아들이고 어떤 요인들이 영향을 미치며 영향관계가 어떻게 형성되는지에 대한 연구가 필요시 되고 있다. 본 연구에서는 스마트폰 뱅킹 서비스를 대상으로 기존의 기술수용모델을 확장?수정하여 유의미한 요인들을 추가하고 모델의 적합성과 각 요인들 간의 관계를 분석할 것이다. 이를 위하여 선행 연구들의 고찰을 토대로 스마트폰 뱅킹 서비스의 지속사용의도를 예측하기 위한 연구 모델을 설계하였으며, 190명 이상의 은행 고객들을 대상으로 수집된 데이터를 가지고 실증분석을 실시하였다. 데이터 분석 결과는 모형에서 제시한 14개의 가설과 모형검증 과정에서 추가된 가설 1개를 포함한 15개의 가설 중 13개의 가설에서 유의미한 영향관계가 검증되었다. 인지된 유용성에 대해서는 자기유효성, 사용경험, 혁신성, 사회적 영향과 같은 개인특성 요인들이 긍정적 영향관계를 갖는 것으로 검증되었으며, 서비스 확장성과 인터페이스 용이성 같은 뱅킹 서비스 특성 요인들도 긍정적 영향관계를 나타내었다. 또한 인지된 편이성에 대해서는 개인특성으로서는 자기유효성이, 뱅킹 서비스 특성으로서는 서비스 확장성, 보안위험, 인터페이스 용이성이 긍정적 영향관계를 형성하는 것으로 나타났다. 그리고 영향요인들에 의해 영향을 받은 인지적 요인들인 유용성과 편이성은 사용자의 지속적 사용의도에 강력한 영향을 미치는 것으로 분석되었다. According to the diffusion of using smart phone, the number of users using smartphone-based banking service is steadily increasing. Because it is unknown whether or not to accept users", it is necessary to study the influence of the factors on the relationship. In this study, the researchers expand and modify the existing technology acceptance model about the smartphone-based banking service and subjoin significant variables in the model and analysis of the relationship between each factor. For these analyzes, a research model is designed to predict the intention of sustainable use based on previous studies. The empirical analysis was conducted with the data collected for service users in more than 190. It was verified that the user characteristics factors including self-efficacy, experience of use, innovativeness, social influence has a positive relationship for the perceived usefulness and the characteristics factors of banking service including service scalability, ease of interface has a positive relationship for the perceived usefulness. It was verified that the self-efficacy among the user characteristics factors only has a positive relationship for the perceived ease of use and the characteristics factors of banking service including service scalability, security risk, ease of interface has a positive relationship for the perceived ease of use. Also It was analyzed that the perceived factors including perceived usefulness and perceived ease of use has a strong influence on the intention of sustainable use.
