About the Lab
Professor Han Sang-il's research spans diverse yet interconnected domains, including civic participation and local governance in urban settings, nonprofit organization performance and organizational learning, mobile banking adoption and technology acceptance, engineering human resource management, and psychological factors in sports performance. His work consistently emphasizes institutional design, behavioral dynamics, and the interplay between social structures and individual outcomes. He applies mixed-methods and structural modeling approaches to understand how leadership, technology, and organizational culture influence performance and well-being in public, nonprofit, and sports contexts.

15세인트폴과 포틀랜드의 참여제도가 다른 지역의 근린참여제도와 구별되는 가장 중요한 특성은 참여의 깊이이다. 즉 공식적인 참여기구가 시정의 거의 모든 분야에 확대되어있어서 주민들은 매우 구체적인 영역까지 참여할 수 있다. 대신 시애틀과 로스앤젤레스는 시정참여보다 근린의회단위의 자체적인 사업을 충실하게 발전시키기 위하여 근린단위의 자율성확보에 치중한다. 그리고 세인트폴과 포틀랜드는 참여의 단위가 작아서 각각의 근린의회가 역사적, 문화적으로 동질성을 유지하기 쉽도록 설계되어 있다. 이러한 제도적인 차이는 아래에 설명될 역사적인 맥락과 무관하지 않다.
Abstract A few dozen dwarf satellite galaxies of the Milky Way have been discovered, which are often viewed as the remaining building blocks of our Galaxy. The follow-up spectroscopy showed that dwarf galaxies have a sizeable spread in their metallicities. Several scenarios were suggested to explain the metallicity spread, which can be tested by the structural patterns of stellar subpopulations with distinct metallicities. However, such chemical plus structural examination, which we refer to as
During the last decade in Korea, non-profit organizations (NPO) have shown incredible growth in both their number and size due to the development of civil society and government-subsidizing policies. Most registered NPOs are subsidized by the government but their learning capacities and financial performance in meeting new social needs in an innovative manner is somewhat limited and even less sustainable. In this article, the authors assume that the learning organization characteristics of NPOs
Based on literature relating to the theory of planned behavior(TPB) and the TAM, this study extends the applicability of the TAM in a mobile banking context, by adding one trust-based construct('perceived credibility') and two resource-based constructs('perceived efficacy' and 'perceived cost') and technical suitability constructs to the model, while paying careful attention to the placing of these constructs in the TAM's existing nomological structure. Data collected from 182 users in Korea wer
Even engineers who have the same job title and are working on the same project have different skills and backgrounds. However, despite the importance of assigning the right person to the right job to ensure successful project delivery, current human resource (HR) allocation practices are only concerned with the list of projects in which a candidate has been involved, years of experience in a discipline, and their previous job titles. As a result, some engineers lack the knowledge and experience
이 연구의 목적은 국립중앙도서관의 서비스 수준이 이용고객에 대한 만족도와 방문회수에 미치는 영향을 밝히는 것이다. 그리고 최근 고객들의 만족도 향상뿐만 아니라 시설의 가동률을 높이고 사회적 일자리를 창출하는 효과를 거둔 성공사례로 인식되고 있는 국립중앙도서관의 연장개관의 효과를 검증하기 위하여 시간대별 인과관계를 구조방정식 모형의 추정으로 검토하였다. 연구결과에 따르면 국립중앙도서관 서비스의 특수성으로 인하여 서비스 수준이 고객의 만족감은 높일지라도 방문회수를 직접적으로 증가시키지 않는 것으로 판명되었다. 그러나 서비스 품질이 높다고 인식하는 이용자는 만족감도 높은 것으로 밝혀졌다. The authors examine the service quality of the National Library of Korea and its effects on the customer satisfaction and the annual number of visit. In particular this a
Reduction of the on-chip memory size is a key issue in video codec system design. Because video codec applications involve complex algorithms that are both data-intensive and control-dependent, memory optimization based on global and precise analysis of data and control dependency is required. We generate a memory-efficient C code from a restricted Simulink model, which can represent both data and control dependency explicitly, by applying two buffer memory optimization techniques: copy removal
