  • Plastic wastes, particularly polyethylene terephthalate (PET) generated from used bottled water constitute a worldwide environmental issue. Reusing the PET waste for geotechnical applications not only reduces environmental burdens of handling the waste, but also improves inherent engineering properties of soil. This paper investigated factors affecting shear strength improvement of PET-mixed residual soil. Four variables were considered: (i) plastic content; (ii) plastic slenderness ratio; (iii) plastic size; and (iv) soil particle size. A series of unconfined compression tests were performed to determine the optimum configurations for promoting the shear strength improvement. The results showed that the optimum slenderness ratio and PET content for shear strength improvement were 1:3 and 1.5%, respectively. Large PET pieces (i.e., $1.0cm^2$) were favorable for fine-grained residual soil, while small PET pieces (i.e., $0.5cm^2$) were favorable for coarse-grained residual soil. Higher shear strength improvement was obtained for PET-mixed coarse-grained residual soil (148%) than fine-grained residual soils (117%). The orientation of plastic pieces in soil and frictional resistance developed between soil particles and PET surface are two important factors affecting the shear strength performance of PET-mixed soil.

  • Background : Strategic planning is an organizationwide or systemwide, ongoing look into the future usually of 2~3 years, based on objective analysis of the current environment and trends, but it can incorporate both short-term and long-term goals. The strategic planning process includes external analysis, internal analysis, issue analysis, development of mission, vision and values, and lastly development of organizational goals and objectives. As a part of the strategic quality planning process, certain service lines, important organizationwide functions, or key processes supporting these functions can be prioritized to expedite and roll out certain strategic goals. This is called strategic quality initiatives. Methods : We organized a quality improvement team, a subgroup of 21st century vision planning corps of our medical center, and pursued QI activities for improvement of healthcare environment, particularly in the admission setting. We developed a strategic quality initiative based on the results of patient satisfaction surveys, and carried out functions of self-directed work team. Results : The strategic goal was to be the benchmark for peer group hospitals in Korea for providing cost-effective best-practice. The QI team included 3 medical doctors, 1 nurse, 1 social worker, and 1 QI consultant as well as many operational members to support services and quality initiatives met every Tuesday for 18 weeks. Outcome objectives were to improve patient satisfaction score. The issues included in the objectives were comfort, temperature, noise, cleanliness of the admission wards, quality and education of patient meals, matters regarding the admission process, and an appurtenant facility such as restaurant or convenience store. Every issue was discussed and recommendations, conclusions and opportunities were implemented. Conclusions : By developing a strategic quality initiative as a part of the strategic quality planning process, and pursuing a self-directed work team, certain sen/ice lines, important organizationwide functions, or key processes supporting these functions can be improved effectively within a short period. Strategic quality initiatives serve to support, or roll out, certain strategic goals that are relevant to performance improvement and development of specific measurable outcome objectives, and associated performance measure for each initiative. Each strategic quality initiative should include a statement of intent outcome objectives, and performance measures. We will come back with follow up of the strategic quality initiative, for improvement of healthcare environment, and results of patient satisfaction re-survey.

  • 현재 국내의 정부 R&D 사업은 300여개에 이르고 있고, 이를 사업의 특성별로 16개 국가R&D 관련 부처 청의 15개 대표연구관리 전문기관에서 각각 관리하고 있다. 이로 인하여 발생하는 국가 R&D에 대한 중복 투자와 체계적인 R&D연구과제 및 성과관리의 미흡으로 R&D 투자의 효율성에 대한 문제가 계속해서 제기되고 있다. 그러한 가운데 이러한 문제를 해결하기 위하여 교육과학기술부는 국가연구개발의 기획에서 성과활용에 이르기까지 연구개발의 효율화를 지원할 수 있는 국가 R&D 포털시스템으로써 국가과학기술종합정보시스템(NTS)을 구축하고 있다. NTIS와 같이 분산된 데이터의 통합시 동일한 의미의 데이터들이 각 조직에서 달리 명명되고 다른 데이터 유형으로 되어 있기에 통합된 데이터의 정확성과 높은 수준의 품질을 달성하는 것이 어려운 문제이다. 본 논문에서는 NTIS 시스템의 인력/과제/성과 정보의 통합DB 구축 및 연계방식과 이를 통해 수집된 데이터의 품질관리를 위한 데이터정제 프로세스를 고찰해 본다. 그 과정에서 발생할 수 있는 데이터 품질문제의 요인을 분석하여 NTIS의 데이터 품질향상을 위한 개선방안을 제시한다.

  • 본 연구는 온라인 설문조사를 통해 수집된 국내 게이머를 대상으로 게임 장르, 이념의 차이가 존재하는 뉴스 미디어, 미디어 매체에 따른 게임 관련 정보 출처가 게이머 이슈 참여에 미치는 영향에 대해 위계적 회귀 분석으로 검증했다 (N= 1,362). 연구 결과 특정 장르의 게임 플레이가 게이머 이슈 참여에 긍정적인 역할을 수행했다. 진보·중도 언론에 보도된 게임 규제 찬반에 대한 집단행동은 독자들의 동원 신호(mobilization cue)로 작용하고 게이머의 사회적 행동을 독려했다. 반면, 상위 조직 및 이익 집단을 정보 출처로 활용한 보수 언론은 현실 참여 사회에 부정적인 영향을 주었다. 게임 이슈에 관한 매스 미디어의 편향된 보도 행태는 게이머가 시정 행동(corrective action)을 통해 사회적, 정치적으로 행동하는데 영향을 주었다. 본 연구는 정치 이념, 게임 장르, 미디어 이용과 사회적 참여의 관계를 실증적으로 분석한 데에 의의가 있다. 게임 규제 정책 제고와 게임 연구의 이론적, 개념적 확장의 필요성이 요구된다는 시사점을 제공한다.

  • As interests in the quality of data in database systems are growing recently, analysis and improvement of data quality in databases have been an important issue. However, there has yet to be a clear agreement on how to reasonably calculate the total cost of such project. In this paper, based on real project data and budget statistics, we develop a model to estimate the cost for quality analysis and improvement project of a database. We first conduct statistical analysis to build our basic model. Throughout this analysis, we have identified factors that determine the scale of works required to conduct the project and eventually determine the cost. In addition, we have identified factors that determine the complexity of the project. These factors can adjusts the cost determined by the scale of works. Our model is verified and improved by surveys on experts. We apply our model to newly conducted projects and observe that our model estimates the cost of each project reasonably well.
