This study relates to develop a quantitative method through which promising technology-based business items can be discovered and selected. For this study, we utilized patent trend analysis, technology-industry concordance analysis, and keyword co-occurrence analysis of US patents. By analyzing patent trends and technology-industry concordance, we were able to find out the emerging industry trends : prevalence of bio industry, service industry, and B2C business. From the direct and co-occurrence analysis of newly discovered patent keywords in the year, 2000, 28 promising business item candidates were extracted. Finally, the promising item candidates were prioritized using 4 business attractiveness determinants; market size, product life cycle, degree of the technological innovation, and coincidence with the industry trends. This result implicates that reliable discovery and selection of promising technology-based business items can be performed by a quantitative, objective and low- cost process using knowledge discovery method from patent database instead of peer review.

This paper proposes an R&D project selection methodology for green technology centered on developing country-oriented technology commercialization. Eight selection criteria are derived from the R&BD logic model : technology needs of developing countries, effectiveness of green technology, technological potentials, domestic technological capability, commercialization feasibility, economic benefits, business feasibility, and spillover effects of developing countries. 21 qualitative and quantitative indicators are then defined for each criterion. The analytic hierarchy process is conducted to produce relative importance of evaluation indicators and to set final priority scores of R&D project candidates. The working of the proposed methodology is provided with the help of a case study example of Green Technology Center. The proposed methodology is expected to be effectively utilized for policy practices of R&D project selection in the field of green technology.

In this study, a target detection algorithm was proposed for using hyperspectral imagery. The proposed algorithm is designed to have minimal processing time, low false alarm rate, and flexible threshold selection. The target detection procedure can be divided into two steps. Initially, candidates of target pixel are extracted using matching ratio of spectral pattern that can be calculated by spectral derivation. Secondly, spectral distance is computed only for those candidates using Euclidean distance. The proposed two-step method showed lower false alarm rate than the Euclidean distance detector applied over the whole image. It also showed much lower processing time as compared to the Mahalanobis distance detector.

Globally, thousands of patients undergo lung transplantation owing to end-stage lung disease each year. As lung transplantation evolves, recommendations and indications are constantly being updated. In 2021, the International Society for Heart and Lung Transplantation published a new consensus document for selecting candidates for lung transplantation. However, it is still difficult to determine appropriate candidates for lung transplantation among patients with complex medical conditions and various diseases. Therefore, it is necessary to analyze each patient's overall situation and medical condition from various perspectives, and ongoing efforts to optimize the analysis will be necessary. The purpose of this study is to review the extant literature and discuss recent updates.

본 논문에서는 OLSR의 MPR 선택방법을 개선함으로써 애드혹(ad hoc) 네트워크의 처리율(throughput), 지연 시간(delay) 등의 성능을 향상시킬 수 있는 S-MPR 선택 방법을 제안한다. OLSR의 MPR 선택 방법은 각 노드가 독립적으로 MPR을 선택하기 때문에 대부분의 노드가 MPR로 선택되는 문제가 있다. 이러한 문제를 해결하기 위해 기존에 제안되었던 MPR 후보(candidate) 선택 방법은 MPR의 수는 감소시킬 수 있지만 그로 인해 경로의 효율성과 네트워크의 연결성(connectivity)이 저하되는 문제를 갖고 있다. 본 논문에서 제안하는 S-MPR 방법은 이러한 문제를 해결하기 위해 각 노드 입장에서 가장 중요한 노드를 S-MPR로 선택하고 나머지 MPR은 MPR 후보를 이용하여 선택하는 방법을 사용한다. 따라서 제안 방법은 경로 효율성의 저하를 최소화하면서 MPR로 선택되는 노드의 수를 줄임으로써 TC 메시지로 인한 오버헤드를 최소화하고 MPR간의 충돌을 감소시킴으로써 처리율, 지연 시간 성능을 향상시킬 수 있다. 본 논문에서 제안한 S-MPR의 성능을 알아보기 위해 OPNET을 활용하여 시뮬레이션을 수행하고 제안 S-MPR의 성능이 가장 우수함을 보인다.

일반아나 학습 부진아를 대상으로 진행된 많은 선행 연구에서 출생월에 따른 학교입학연령이 아동의 학업성취에 중요한 영향을 미치는 것으로 밝혀 왔으며, 우리나라 영재아를 대상으로 진행된 본 연구에서도 이러한 양상은 그대로 적용되는 것으로 나타났다. 과학영재교육원 초 중등 영재선발 과정에 응시한, 그리고 영재로 선발된 아동의 구성원이 학교입학연령에 따라 어떠한 양상을 나타내는지 알아본 결과, 2006, 2007학년도 영재선발 응시자 및 합격자 그룹 모두 각 학년에서 나이가 가장 많은 봄 출생아의 수가 월등히 많은 것으로 나타났다. 또한 이러한 초등학교 입학연령은 초등학교뿐만 아니라 중학교 단계에까지 아동의 학업성취에 영향을 미친다는 점이 밝혀졌다. 이러한 연구 결과들을 바탕으로 학교입학연령에 따른 아동의 학업성취의 차는 이들의 성숙의 차를 의미할 수 있다는 결론을 내리게 되며 또다른 아동에 비해 일찍 학교를 입학한 상당수의 아동이 학업성취에 있어서 열세하다는 시사점도 얻게 된다. 이 외에도 이러한 요인이 일반아와 부진아뿐만 아니라 영재선발에까지도 중요한 변인으로 작용한다는 결론은 우리가 주의 깊게 고려해 보아야 할 부분일 것이다.

The methods of selection through observations and recommendations were introduced in the process of recruiting new students for the science education institutes for the gifted attached to 25 universities recently. This paper itemized the methods of screening through observations and recommendations. This paper also analyzed the problems with the methods and attempted to create plans for their improvement. The methods of selection through observations and recommendations led to the positive results that students' usual activities and attitudes in the classroom were reflected on the evaluation and that the cost of their private lessons was also reduced. However, the methods showed a few problems that need to be corrected. We point out problems occurring with examining their documents for submission and interviews. It was not easy to grade candidates' gifts, creativity, potential and development within the contents of the documents and the limited time of conducting interviews. On the plans for the developments of the implemented methods of selection through observations and recommendations, we have several suggestions. The chances for teachers' in-service training of learning the methods of selection through observations and recommendations need to be expanded. The interview needs to be enhanced and to have the same weight as the document screening. To secure the continuity of the education for the gifted, the clear guidelines from the Ministry of Education, Science, Technology along with the cooperation of the education institutes for the gifted are essential.

To data, there was no systematic basis for establishing the content and allowed levels of general contamination substances in the Korean groundwater quality standards for non-drinking water. Recently, use of specific procedures for deriving valid groundwater quality standards have become mandatory. This study first investigated the methodology for deriving groundwater quality standards in the European Commission (EC), considering background groundwater quality and domestic and international standards related to water quality. Furthermore, this study investigated the existing specified procedure of standards related to water quality (e.g. surface water, drinking water, and wastewater). Our findings showed that EC and Member States presented the methods for deriving groundwater threshold values for general chemicals. Finally, we have proposed the following procedures of deriving Korean groundwater quality: (1) Selection of groundwater pollutant population, (2) selection and monitoring of priority substances, (3) monitoring, (4) selection of groundwater quality standard candidates, (5) selection of new substances and values for groundwater quality standards.
