Restoration to improve the ecological quality of Mt. Nam was explored in a viewpoint of restoration in both landscape and ecosystem levels. A restoration plan in landscape level was based on the result on the land-use pattern in Mt. Nam including its surrounding area and that in ecosystem level on the ecological quality of each landscape element. A plant to construct the green network, which extending from Mt. Nam to the Han river through the Yongsan family park and through the Eungbong urban park was prepared as a restoration project in landscape level to improve the ecological quality of Mt. Nam as an ecological park. On the other hand, a plan for restoration and creation of biotop as a restoration project in ecosystem level was also prepared to improve the ecological quality of each green area consisting green network. Green areas composing green network include keystone green area (Mt. Nam), green stations (Yongsan family park, Eungbong urban park, and the han river citizen's park), and green pathway (or ecological corridor) connecting those green areas.

Purpose: This study aimed to explore methods to improve the quality recognition and satisfaction level of non-face-to-face lectures among students in the departments of dental technology and dental hygiene. Methods: This survey was conducted to assess the status and preference of non-face-to-face lectures and the level of awareness and satisfaction regarding the quality of these lectures among 179 students of dental technology and 295 students of dental hygiene. Statistical analyses were performed using frequency analysis, independent sample t-test, one-way ANOVA (post-hoc Duncan), Welch analysis (post-hoc Games-Howell), and hierarchical multiple regression analysis. Results: Factors that affected the ability to assess the quality of non-face-to-face lectures were the department, the method of non-face-to-face lectures, the most preferred method for conducting lectures, the level of awareness regarding the quality of face-to-face lecture, and satisfaction level. It has 71.5% explanatory power. Moreover, factors that influenced the satisfaction level of non-face-to-face lectures included the department, grade, the highest satisfied non-face-to-face teaching method, the most effective theoretical non-face-to-face teaching method, the most preferred teaching methods, and the ability to assess quality of face-to-face lectures. It has 46.8% explanatory power. Conclusion: Non-face-to-face classes should be designed and developed for web-based programs to improve the motivation and achievement level of the students and encourage interaction between the professors and students. Our findings suggest that educators should strive to achieve optimal educational effects by efficiently combining face-to-face and non-face-to-face lectures.

본 연구의 목적은 지문인식 평가용 데이터베이스의 난이도(Level of Difficulty)를 지문영상 품질 평가를 통하여 정량화 하는 것이다. 본 논문에서는 지문 데이터베이스의 난이도 정량화 방법으로 품질 분포도 분석 방법과 품질 차이 분석 방법을 제안한다. 품질 분포도 분석 방법은 지문 영상의 품진 등급별 빈도수를 기반으로 데이터베이스 전체의 난이도를 표현한 방법이고, 품질 차이 분석 방법은 데이터베이스를 구성하는 동일 지문의 영상들 간의 각 품질 차이별 빈도수를 동시발생 매트릭스(Co-occurrence Matrices)를 이용하여 난이도로 나타낸 방법이다. 두 방법론에 의한 실험 결과 지문영상 품질 기반의 데이터베이스의 난이도는 인식 성능과 상관관계를 가지며, 품질 분포도 기반의 난이도보다 품질 차이 기반의 난이도가 더 높은 상관관계를 보임을 확인할 수 있었다. 특히 MPQ(Matching Pairwise Qualities) 동시발생 매트릭스의 OQ(Opposite Qualities) Block 기반의 난이도 정량화 방법이 인식 성능과 가장 높은 상관관계를 나타내는 것을 알 수 있었다. 본 연구를 통해 지문영상 품질 기반의 지문 데이터베이스의 난이도를 정량화할 수 있었고, 난이도와 인식성능이 높은 상관관계를 가짐을 알 수 있다.

정부는 공공데이터의 품질관리 수준을 평가하기 위해 국제표준을 기반으로 공공데이터 품질관리 조직 성숙도 모델을 개발하였다. 그러나 현장에 적용하기에는 평가항목이 너무 많다는 지적에 따라 평가지표 수를 축소한 새로운 모델을 보완 개발하였다. 이를 위하여 프로세스를 통합 및 조정하여 프로세스 수를 축소하였으며 프로세스능력수준이 아닌 새로운 활동능력수준 기반의 평가 방식을 제안하였다. 또한, 공공데이터 품질관리 성숙수준을 다섯 개의 레벨로 표현하는 방식과 1~5 사이의 실수로 표현하는 방식을 제안하였다. 그리고 새로 제안한 모델의 특성을 기존의 조직 성숙도 모델과 비교 분석하였다.

This paper studies the effect of information quality level and customer demand on performance measures in a supply chain. The information quality level compares 2 types, the information levels of a customer demand and a lead time. The customer demand process follows a general auto-correlated AR(1) process without seasonality. In the AR(1) process, ${\sigma}$ indicates the degree of demand fluctuation and ${\rho}$ means the trend of customer demand. ANOVA tests using a 5% significance level are performed in SPSS to examine significant performance changes among various cases.

The literature reveals that service quality is critical determinants affecting customer satisfaction in the retail industry. Recent online B2C studies also show that service quality significantly influences online customer satisfaction. However, research on analyzing antecedents to determine the service quality level of online shopping has not been sufficiently reported. Moreover, the offline synergy effect on the Internet shopping mall has been presented mostly at a conceptual level. The purpose of this study is to investigate key managerial variables exploiting offline synergy, including pure online attributes, that impact on service quality of the click and mortar Internet shopping mall. A survey was conducted for empirical validation of the hypotheses. The results indicate that core offline synergy factors significantly enhance the perceived service quality level of the Internet shopping mall. Implications, limitations, and future research directions are also discussed.

본 연구는 한강권역 농업용 소하천 88지점에 대하여 현재의 수질상태를 고려하여 수질등급모형을 구축하고자 실시하였다. 10개의 수질항목에 대하여 각 수질항목별 상위 20%씩 level을 부여한 후, 최저 등급을 기준으로 전체 수질등급을 부여하였는데, Level I에 해당하는 하천은 없었고, Level II는 1지점, Level III은 3지점, Level IV는 22지점, Level V는 62지점으로 조사되어 등급이 낮은 Level V로 갈수록 많은 하천들이 속하였다. 집단간 차이의 유무를 알아보기 위해 집단 평균의 동질성을 검정한 결과, DO, BOD, $COD_{Cr},\;NH_3-N$, 그리고 SS가 집단 간에 차이가 없는 것으로 조사되어 판별분석 시에는 제외되었다. 판별력이 가장 뛰어난 $NO_3-N$가 수질등급에 관여하는 변수로 선택되었으며, 분류함수계수에 의한 각 수질등급별 등급모형은 Level II=$-4.648+3.246{\times}[NO_3-N]$, Level III=$-5.084+3.456{\times}[NO_3-N]$, Level IV=$-4.298+3.067{\times}[NO_3-N]$, Level V=$-7.369+4.396{\times}[NO_3-N]$로 구축되었고, 적합도 평가에 의한 구축된 수질 등급모형의 적합도는 88.4%로 조사되어 높은 적합도를 보였지만, 향후 더 많은 자료의 확보와 축적으로 수질등급모형이 수정, 보완된다면 활용가능성은 더 높을 것으로 판단되며, 이를 바탕으로 각 권역별로도 실제 수질에 적합한 수질등급모형을 구축할 수 있으리라 생각된다.
