This study aims to study the learning attitudes and tendencies of learners in helicopter pilot training, examine their influence on flight training performance, and apply them to flight teaching methods. To this end, exploratory factor analysis was conducted based on the questionnaire results to measure the learning attitudes and tendencies of learners, and major learning-related factors were derived. Then, regression analysis on educational performance was performed to analyze their influence on flight training performance. As a result, it was found that the higher the learner's resilience and mastery goal-oriented learning attitude, the more positively they had an influence on flight training performance. This reconfirmed the fact that the role of the flight instructor and a high level of personal motivation or effort in the limited space of the cockpit affect flight training performance.

본 논문은 요양보호사의 교육에 참가한 교육생들의 교육 참여동기가 교육만족도에 미치는 영향을 알아봄으로서, 요양보호사 교육의 질 향상에 기여하고자 실시하였다. 본 연구는 B시에 소재하고 있는 요양보호사 교육원의 교육생 281명을 대상으로 교육 참여동기와 교육만족도에 대한 조사를 실시하였다. 통계처리는 SPSS 12.0을 사용하여 신뢰도와 타당도를 검증하였고 기술통계와 요인분석, 회귀분석을 실시하였다. 교육 참여동기 중 활동지향형이 가장 높게 나타났으며 교육만족도는 지도강사에 대한 만족도가 가장 높았다. 교육 참여동기가 교육만족도에 미치는 영향은 학습지향성과 활동지향성으로 나타났으나 목표지향성은 교육만족도에 영향력을 미치지 않는 것으로 나타났다. 따라서, 요양보호사 교육생들의 교육 만족도는 중간이상으로 높았으며, 교육 참여동기는 교육만족도에 영향을 미치는 것으로 나타났다.

본 연구는 기업이 지향하는 고객가치에 따라 공급사슬통합 수준에 차이가 있을 것이라는 가정 하에 자료 수집을 통해 공급사슬통합 유형을 분류한 뒤, 각 유형별로 고객가치 및 기업성과에 차이가 있는지를 검정하고자 하였다. 그 결과, 5가지 공급사슬통합 유형(높은 내부지향 통합, 중간 내부지향 통합, 높은 공급사슬통합, 높은 고객지향 통합, 중간 외부지향 통합)이 분류되어 기업들이 공급사슬통합의 개별 차원에 집중하는 정도가 서로 다르다는 것이 밝혀졌다. 또한, 공급사슬통합의 5가지 유형들 간에 지향하는 고객가치 및 기업성과에도 차이가 있는 것으로 나타났다. 품질과 납기의 중요성을 지향하는 기업들은 외부 통합에 집중하고 있으며, 외부 통합의 수준이 높은 기업들은 재무성과보다는 고객성과가 더 높은 것으로 밝혀졌다. 이러한 연구결과는 기업들이 중점적으로 추구하는 고객가치를 실현하기 위해서 어떠한 공급사슬통합 전략을 수립하여 접근해야 하는지에 대한 시사점을 제공해 줄 것이다.

Sensor placement is a crucial aspect of bridge health monitoring (BHM) dedicated to accurately estimate and locate structural damages. In addressing this goal, a sensor placement framework based on the deflection influence line (DIL) analysis is here proposed, for the optimal design of damage detection-oriented BHM system. In order to improve damage detection accuracy, we explore the change of global stiffness matrix, damage coefficient matrix and DIL vector caused by structural damage, and thus develop a novel sensor placement framework based on the Fisher information matrix. Our approach seeks to determine the contribution of each sensing node to damage detection, and adopts a distance correction coefficient to eliminate the information redundancy among sensors. The proposed damage detection-oriented optimal sensor placement (OSP) method is verified by two examples: (1) a numerically simulated three-span continuous beam, and (2) the Pinghu bridge which has existing real damage conditions. These two examples verify the performance of the distance corrected damage sensitivity of influence line (DSIL) method in significantly higher contribution to damage detection and lower information redundancy, and demonstrate the proposed OSP framework can be potentially employed in BHM practices.

The dynamic cast operation allows flexibility in the design and use of data management facilities in object-oriented programs. Dynamic cast has an important role in the implementation of the Data Management Services (DMS) of the Mission Data System Project (MDS), the Jet Propulsion Laboratory's experimental work for providing a state-based and goal-oriented unified architecture for testing and development of mission software. DMS is responsible for the storage and transport of control and scientific data in a remote autonomous spacecraft. Like similar operators in other languages, the C++ dynamic cast operator does not provide the timing guarantees needed for hard real-time embedded systems. In a recent study, Gibbs and Stroustrup (G&S) devised a dynamic cast implementation strategy that guarantees fast constant-time performance. This paper presents the definition and application of a cosimulation framework to formally verify and evaluate the G&S fast dynamic casting scheme and its applicability in the Mission Data System DMS application. We describe the systematic process of model-based simulation and analysis that has led to performance improvement of the G&S algorithm's heuristics by about a factor of 2. In this work we introduce and apply a library for extracting semantic information from C++ source code that helps us deliver a practical and verifiable implementation of the fast dynamic casting algorithm.

Administrative city has been developed step by step aiming to being a public transport-oriented new city. In spite of its primary goal, administrative city is dominated by car-oriented tansportaion system because the supply of public transportation has not been adequately and timely performed. In this study, we investigate the current situation related to (public) transportation use in administrative city. Also, we examine the issues of traffic system through a survey on residents' consciousness about public transportation use. Additionally, the analysis of demand elasticity according to the change of the conditions of using public transportation and passenger car is conducted for passenger car users. As a result, it is analyzed that as the neighborhood is more stabilized after the completion of development the resistance to the abandonment of passenger car is higher when the tide demand control method is introduced. Therefore, it is concluded that pre-emptive public transportation supply and the management of car demand management are necessary for the activation of public transportation in Administrative city.

The goal of this study is to examine municipality comprehensive plans by recognizing the problem that adverse impacts of urban regeneration impede the sustainability of specific renewal project. 10 major cities in Korea that are experiencing urban decline were chosen for the study area and plan evaluation indexes were adopted based on the sustainable urban regeneration principles in terms of environmental, social, and economic aspects. Plan evaluation was conducted by employing the content analysis method and developed assessment indexes for three sectors (factual basis, goal/objective, and policy/action) of plan. The findings show that policies, such as 'expansion of parks in urban area,' 'pedestrian-oriented street improvement project,' and 'countermeasures for local industry revitalization,' should be fundamentally included in adopting sustainable urban regeneration plans. Plan scores regarding sustainable urban regeneration had an insignificant relationship with the status of administrative district and plan adopted year. This is because metropolitan municipalities, including Ulsan, Daejeon, and Daegu, received relatively low plan score compared to local governments like Goyang and Suwon. Also, Daegu and Suwon, which established their comprehensive plan in 2018 obtained lower score than Seoul and Incheon, where its plans were created before 2015. Evaluation protocol and indexes that were suggested in this study can be used while reorganizing each locality's comprehensive plan, and thus, play as one of major bases in preparing future sustainable urban regeneration projects.

The purpose of this study was to analyze the casual relationship of the background variables. 4-value orientations. 5 money spending styles and the money management behavior of high school girls. The subjects were 498 high school girls. We used Cronbach\` $\alpha$. Pearson correlation coefficients multiple regression and path analysis as statistical analysis. The results were summarized as follows Resulting from path analysis, the money spending styles were the most influential variable on money management behavior and value orientations were more influential variable on the money spending styles rather than the money management behavior. The money management behavior of high school girls had the directive linear relationships with the variables such as goal-oriented value and 4 money spending styles-security conspicuous. non-monetary and unconcerned.

Purpose: This concept analysis was done to clarify therapeutic intervention in nursing. Methods: For this study the process of Walker & Avant's concept analysis was used. Twenty-nine studies from electronic data bases met criteria for selection. Results: Therapeutic intervention can be defined by the following attributes: 1) goal-oriented, 2) forming a therapeutic relationship, 3) reinforcement of coping ability, 4) patient-centered, 5) a holistic integrated approach. The consequences of therapeutic intervention were improvement of quality of life, coping skills, self-care. Conclusion: Attributes of therapeutic intervention identified in this study can be applied to develop tools for measuring therapeutic nursing behaviors or to develop therapeutic nursing intervention programs for patient or family.
