본 연구에서는 질적연구방법인 Q방법론을 적용하여 대학생들을 대상으로 학과 점퍼에 대해서 어떤 생각을 가지고 있는지에 대한 주관적 평가와 인식 유형별 특성을 알아보고자 하였다. 제1유형의 경우 학과 점퍼는 학과에 대한 소속감을 주고 학과를 홍보하는 역할을 한다고 인식하였다. 또, 학과 점퍼를 착용하면 행동을 조심하게 되지만, 활동이 편하고 주변 사람들의 좋은 평가를 이끌어내며 나의 신뢰감을 높여주는 효과가 있다고 생각하는 것으로 분석되었다. 제2유형의 경우 학과 점퍼는 활동하기 편하고 유행을 따르지 않는 무난한 디자인이라 만족스러우며, 학교 갈 때 늘 착용한다고 하였다. 제3유형은 학과 점퍼를 착용하면 동질감과 소속감을 준다고 하였고, 학과 점퍼가 유행을 따라가는 스타일이면 좋겠다고 생각하며 학과 점퍼 착용에 긍정적이고 잘 맞는다고 생각하는 유형이다. 대학생들의 학과 점퍼도 하나의 유니폼으로써 기능을 할 수 있도록 학과의 이미지나 상징성을 잘 나타내고, 활동량이 많은 대학생들의 신체적 특징을 반영하여 맞음새가 우수한 학과 점퍼가 개발되어야 할 것으로 생각된다.

A hydrological drought index, MSWSI (Modified Surface Water Supply Index) was suggested based on SWSI. South Korea was divided into 32 regions considering the distribution of available gauge station of precipitation, dam storage, stream water level and natural groundwater level. The indices estimated in the regions represent a spatially distribution of drought. Monthly MSWSI was evaluated for the period of 1974 and 2001. The result was compared with PDSI and checked the applicability of the suggested index in our hydrologic drought situation.

한국과 인도 간 관계(이후 한국-인도 관계)는 오랜 역사를 통해 정치, 사회, 경제 및 전략적 측면에서 지속적으로 발전되었다. 특히 인도의 "동방정책(Look East Policy)" 채택과 한국의 "중견국 외교(Middle-power diplomacy)" 선언 간 동질성을 모색하는 차원에서 최근에 더욱 긴밀히 발전되고 있다. 즉 최근에 이르러 갑자기 발전된 관계가 아니라는 논지이다. 이에 본 논문에서는 한국과 인도 간 관계를 역사적 시각, 탈냉전 이후 시각, 경제적 시각 및 교육 및 문화적 그리고 지정학적 시각에서 평가하고자 한다. 특히 역내 중견국(middle power) 대표적 국가를 활용한 긴밀한 전략적 협력을 강조하고자 한다. 이를 위해 2004년 노무현 대통령의 인도 공식 방문 이후 2015년 1월 박근혜 대통령의 방문까지의 양국 간 전략적 협력 관계를 조명해 본다. 이에 따라 양국 관계는 이미 공개된 바와 같이 이는 사이버, 방산, 군사협력 및 정보교환 등의 분야로 구체화되고 있다. 일부는 이를 중국을 견제하는 양국 간의 협력이라고 평가하나, 본 논문은 특정 국가를 지목하기보다, 역내 중견국으로서의 전략적 관계 증진을 통한 역내 이익 보호에 있다고 평가한다. 특히 양국 간을 지리적으로 연결하는 해양을 통한 해양협력에 대한 논의를 추가한다. 예를 들면 역내 자연재난 구조작전(DR operation) 및 인도주의 지원작전(HA operation) 해양협력과 현재 진행되고 있는 아덴만 해적퇴치작전(Anti-piracy naval operation)이다.

The purpose of this study is to analyze the effects of the simulation-based professional cardiac resuscitation training on the performance of professional cardiac resuscitation performed by paramedics in the pre-hospital stage and to provide basic data for effective cardiac resuscitation. This study is an experimental study of the design before and after the control of non-equality. The subjects of this study were 16 newly recruited paramedics from K firefighting school. The simulation training program and evaluation papers used as the evaluation tool were reviewed and commented by 6 ACLS simulation experts (2 emergency medical doctor, 2 emergency medical professors, 2 KALS instructors)Respectively. The training consisted of 30 minutes of theory and 150 minutes of practical training. The lecturer first demonstrated for 5 minutes, and after training by individual debriefing after individual training, individual and team education was conducted The evaluation scale was given a 5 - point Likert scale. The SPSS 22.0 program for Windows was used. The general characteristics of the subjects were analyzed for frequency, the examination of homogeneity between the experimental group and the control group wasfulfilled by t test, and the difference test between the groups of the two groups was performed using the paired t-test. The homogeneity test was able to confirm the homogeneity between experimental group and control group. In the evaluation of six ACLS techniques, it was proven that the experimental group that received the simulation training had better performance in all aspects than the non - training control group. The following are the technical items to be performed. 1. Electrocardiogram 2. Specialized instrument 3. Treatment of fluid 4. Leadership and teamwork 5. Medical guidance 6. Evaluation during transfer. It was proved that paramedics who received simulation training were improved on their job performance ability than general lecture and training group. Therefore, if simulation training and education are applied to a student in the synthetic course or an emergency resident who is engaged in clinical practice, he / she will be able to perform his / her duties more proficiently. It is expected that emergency services provided to patients with cardiac arrest will be improved.

The purpose of this study is to find ways to establish and operate Process-focused Assessment in the classroom as the 2015 revised curriculum has emerged. As a way of doing so, we proposed a Process-focused Assessment through self-assessment and looked at the impact of the applied classes on the mathematical academic performance and affective domain of fifth-grade elementary school students. After selecting two classes of fifth grade with proven homogeneity for research, the experimental group applied Process-focused Assessment through self-assessment and the teacher-led Process-focused Assessment to the comparative group. As a result, it was confirmed that the classes applying Process-focused Assessment through self-assessment significantly improved the math and academic performance of fifth-grade elementary school students. The affective domain of the experimental group did not change significantly, but the analysis of the students' comments and interview data showed that they had more interest and confidence in mathematics.

우리나라 하천관리의 패러다임은 1990년대 이후 기존의 치수 및 이수능력을 고려함과 동시에 하천환경의 보전 및 복원을 새로운 목표로 설정한 자연친화적 방식으로 변화되었다. 하천법령 및 제도적 측면에서도 수자원 장기종합계획 및 유역 종합 치수계획은 하천의 환경보전 및 다목적 이용계획을 포함하도록 규정하고 있으며, 국내 하천법에 따르면 하천기본계획 수립 또한 자연친화적 하천조성 및 이와 관련된 보전지구 지정 등을 포함하도록 규정하고 있다. 하천설계기준, 자연 친화적 하천관리에 관한 통합지침, 또는 수자원 장기종합계획에서 적용하고 있는 하천환경조사 및 평가지표는 서로 다를 뿐만 아니라 과학적인 근거가 명확하지 않는 등 국가차원의 표준화가 이루어지지 못한 상태라 할 수 있다. 1990년대 이후 미국, 독일, 영국, 호주 등 선진국들은 하천환경 복원사업의 추진과정에서 복원사업의 타당성 제고 및 성공적인 사업수행을 위하여 그들 국가의 하천특성에 적합한 하천환경 평가 체계를 구축한 바 있으며, 이들 평가체계는 새로운 과학적 지식과 기술의 축적에 힘입어 지속적으로 발전되고 있다. Fujita의 유형화(Segment 분류)법에 의하면, 하천구간(Segment)은 하상경사, 하상재료, 식생, 생태 등이 통계적으로 동질인 하천 구간으로서, 하도 특성과 하천생태계 공간을 구분하는 단위이다. 자연하천에서 동일한 경사를 갖는 하천구간은 하상재료, 소류력, 저수로 폭, 수심 등이 대체로 동일한 값을 나타내고 있으며, 하도 특성을 지배하는 주요 인자로 각 하천의 평균 연최대유량, 하상재료의 대표입경, 하상경사 등을 설정하고 있다. 본 연구에서는 하천구간을 유형화하는 기준을 하상경사로 적용하여 평가단위를 분류하였으며, 평가체계는 미국의 USEPA를 한국형 하천환경에 맞도록 수정보완 하였다. 특히 미국의 USEPA의 지표 중 하안영역의 식생피복, 하반림 등은 생물분야 식생영역과 상충되어 제외하고 우리나라 특성에 적합한 하천횡단형상, 하천횡단 구조물 등의 평가기준을 재정립하여 내성천에 평가적용 분석하였다. 하천환경의 수리 및 하도 특성 평가기준 개발에 따라 평가체계의 개념적 틀을 토대로 통합적이고 표준화된 한국형 하천평가기준 개발을 위한 방법론을 정립하고, 나아가 하천환경의 지속가능성을 전제로 한 하천복원사업의 장 단기적 성공 여부를 평가할 수 있는 실무지침의 과학적 근거를 제시하고자 한다.

The purpose of this study is to find out the importance of process - based evaluation and to find a way to set up and operate the formative assessment which is getting attention. As one of the ways, we investigated the effect of formative assessment through student's interactive feedback on mathematics achievement and attitude of fourth grade students in elementary school. In order to conduct the study, two groups of homogeneous grades were selected. In the experimental group, formative assessment was conducted through student's interactive feedback. In comparison group, formative assessment was conducted through self - confirmation feedback. Statistical analysis of the results after the experiment showed that the formative assessment through student's interactive feedback was found to have a positive effect on the improvement of mathematics achievement. In addition, the formative assessment through student's interactive feedback positively changed the mathematics attitude. Therefore, this suggests that applicability of formative assessment through student's interactive feedback in elementary school classroom instruction, as well as implications for follow - up study for effective implementation of formative assessment.

The non-homogeneous Poisson process(NHPP) based software reliability growth models are proved quite successful in practical software reliability engineering. The fault detection rate is usually assumed to be the continuous and monotonic function. However, the fault detection rate can be affected by many factors such as the testing strategy, running environment and resource allocation. This paper describes a parameter estimation of software reliability growth model with change-point problem. We obtain the maximum likelihood estimate(MLE) and least square estimate(LSE), and compare goodness-of-fit.

This paper proposes a fault detection method utilizing converted images of acoustic emission signals and texture analysis for identifying bearing's multi-faults which frequently occur in an induction motor. The proposed method analyzes three texture features from the converted images of multi-faults: multi-faults image's entropy, homogeneity, and energy. These extracted features are then used as inputs of a fuzzy-ARTMAP to identify each multi-fault including outer-inner, inner-roller, and outer-roller. The experimental results using ten times trials indicate that the proposed method achieves 100% accuracy in the fault classification.

The purpose of this study is to develop an optimization model for reconstructing local administrative districts using spatial analysis and modeling. For this, literature related to reorganization of local administrative systems was critically reviewed and criteria for redistricting were extracted. An optimization model for reconstructing administrative districts was formulated based on these criteria. The model considered three criteria; homogeneity within a reconstructed district, equity among reconstructed districts, and spatial arrangement. Homogeneity for relieving spatial mismatch between administrative and living(economic) boundaries is measured by spatial interaction within a district. Equity among districts is evaluated using population, area, and financial independence. Finally, spatial arrangement is measured by compactness and contiguity. The developed optimization model was implemented using Automated Zoning Procedure(AZP) in GIS environment and applied to a problem aggregating Si-Gun administrative units into broader districts. Application results demonstrate that the model can provide optimal districts according to alternative objective functions.
