Among acoustic signal analysis tasks, acoustic context awareness is one of the most formidable tasks in terms of complexity since it requires sophisticated understanding of individual acoustic events. In conventional context awareness methods, individual acoustic event detection or recognition is employed to generate a relevant decision on the impending context. However this approach may produce poorly performing decision results in practical situations due to the possibility of events occurring simultaneously or the acoustically similar events that are difficult to distinguish with each other. Particularly, the babble noise acoustic event occurring at a bus or subway environment may create confusion to context awareness task since babbling is similar in any environment. Therefore in this paper, a frequency-cepstral feature vector is proposed to mitigate the confusion problem during the situation awareness task of binary decisions: bus or metro. By employing the Support Vector Machine (SVM) as the classifier, the proposed feature vector scheme is shown to produce better performance than the conventional scheme.

In the context of the convergence revolution that brings together culture, technology, and humanities, the fashion industry is aiming to form product strategies to create added value. The ultimate aim of these strategies is to satisfy consumers' diverse needs. Boosted by discussions on sustainability in the fashion industry, sustainability management activities are also emerging as a trend in product strategy. Therefore, it is important to consider both convergence and sustainability management activities together as drivers of fashion brands' product strategies. The main objectives of this study are as follows: (1) to examine the differences in sustainability evaluation by product strategy, (2) to determine how sustainability evaluation affects brand attitude and purchase intention, and (3) to identify how this effect varies according to the types of convergence and sustainability management activities. The main findings of this research are as follows. First, sustainability evaluation varies according to fashion brands' product strategy. Second, evaluation has a positive effect on brand attitude and purchase intention. Third, the effect varies according to the types of convergence and sustainability management activities. This study is an extension of previous research for combining fashion brands' convergence and sustainability management activities as a part of their product strategy, which, in turn, contributes to positive consumer responses on the marketing level.

The importance of clear and effective communication at sea has been greatly emphasized due to the increase in multiculturalism on board both ocean-going and coastal vessels, and the necessity of systematic English training based on 'Knowledge, Understanding, and Proficiency' specified in STCW has also been recognized. With these growing needs in mind, the International Maritime Organization (IMO) updated the Maritime English (ME) Model Course 3.17 in 2015 by providing guidelines on language education within two separate categories, General Maritime English (GME) and Specialized Maritime English (SME). The IMO is now attempting to create a new, global framework of ME education and training, and this this new course model must first be thoroughly understood in order to explore the ways to apply the modified version into the context of current ME education in Korea and to design an updated language curriculum. Therefore, the general structural features of the new model course will be explained in this paper, and the course focus set by IMO and to be considered and/or adopted by the Republic of Korea will be closely examined. Finally, suggestions will be made on how to implement this revised model course in practice with the following focus: the development of localized curriculum for GME and SME; the provision of practical teaching guidance through relevant online and offline materials for class and self-study; and the establishment of qualification guidelines and a teaching support system for language teachers in maritime and language education.

Implementation of Model-based Systems Engineering(MBSE) depends on a model supporting efficient communication among engineers from various domains. And SysML is designed to create models supporting MBSE but unfortunately, SysML itself is not practical enough to be used in real-world engineering projects. SysML is designed to express generic systems and requires specialized knowledge, so a model written in SysML is less capable of supporting communication between a systems engineer and a sub-system engineer. Domain Specific Languages(DSL) can be a great solution to overcome the weakness of the standard SysML. A SysML based DSL means a customized SysML for a specific engineering domain. Unfortunately, current researches on SysML Domain Specific Language(DSL) for the plant engineering industry are still on the early stage. So as the first step, we have developed our own SysML based Piping & Instrumentation Diagram (P&ID) creation environment and P&ID itself of a specific plant system, using a widely used SysML authoring tool called MagicDraw. P&ID is one of the most critical output during the plant design phase, which contains all information required for the plant construction phase. So a SysML based P&ID has a great potential to enhance the communication among plant engineers of various disciplines.

This study aims to create assessment tools for the development fund for women, and to assess the business performance of the organizations using this development fund for women on the basis of such tools. A total of 57 projects by 58 organizations were assessed for a period of eight months. The assessment was carried out by using five tools: 1) examining the weight of the assessment tools, 2) visiting and inspecting project sites, 3) visiting and inspecting the offices of the participating organizations, 4) cooperating with the Seoul Metropolitan Government for municipal administration, and 5) assessing the final project report. Each tool was comprised of three elements: ability of relevant organizations, operational procedure, and projects results. The assessment results are summarized below: 1. According to the examination of the general trends in assessing the organizations that received the Development Fund for Women, it was found that the assessment emphasized performance more than the process involved in the project. Thus, the result suggested that the projects should be carried out more aggressively. 2. Regression analysis was conducted to identify the capability of the organizations in performing the projects with the development fund for women and the capability of the subjects as an independent variable. It was observed that such capabilities were affected by the degree of role sharing and the utilization of internal organizations. It suggested the importance of human resources. 3. To motivate the subjects involved in executing the projects with the use of the Development Fund for Women, the requirements and the satisfaction factors suggested strengthening the scope of financial support and activating the project environment. In conclusion, it is considered that the findings would provide practical ways to improve the system in using the Development Fund for Women, and in setting relevant policies in the future.

The purpose of this study was to identify the effects of clinical nurses' emotional labor and professionalism, and verify the moderating effects of social support on nursing performance. A survey was conducted with 230 nurses working in general hospitals using self-reporting questionnaires in Seoul. It was found that the number of years in current department, professionalism, social support, and deep acting of emotional labor were affecting nursing performance. Social support perceived by clinical nurses moderates the deep acting of emotional labor and it positively influenced nursing performance. Results of this study indicate that nurse managers should focus on increasing nurses' professionalism and social support, and create working environments where nurses do more deep acting of emotional labor in order to increase nursing performance. This study contribute nurse managers to recognizing the impact of emotional labor, professionalism, and social support on nursing performance. Practical programs for increasing clinical nurses' professionalism, social support and decrease emotional labor is required to be developed in further research.

The purpose of this study was to develop an educational program designed to allow students to experience 'up-cycling' first-hand during class and understand its significance by helping them improving their practical problem-solving abilities. Teachers of home economics, Korean, and social studies to third grade middle schooler were asked to analyze the curriculums of their subjects. The analysis results were then used to identify common elements among the units, reconstruct the curriculums, and develop an integrated lesson program to offer integrated activities. Based on these, a lesson program was developed to make an eco-bag and running shoes under the theme of 'up-cycling' in the unit of 'environmentally-friendly clothing and mending of clothes' in the home economics subject. The results were as follows: First, a topical fusion lesson program was developed to integrate three subjects together. The development process involved the integration of the topic of up-cycling, a program model for integrated lessons, and a teaching and learning process plan for topical integrated education. Secondly, a lesson program for home economics was developed that was applicable to actual home economics lessons based on the topical integrated lesson program. The lesson domains were divided into large, medium, and small to create a ten-lesson teaching and learning process plan needed for the lessons, teaching materials that could be put to actual uses in lessons, and activity and evaluation logs for learners.

Recent spatial information technology has brought innovative improvement in both efficiency and accuracy. Especially, airborne LiDAR system(ALS) is one of the practical sensors to obtain 3D spatial information. Constructing reliable 3D spatial data infrastructure is world wide issue and most of the significant tasks involved with modeling manmade objects. This study aims to create a test data set for developing automatic building modeling methods by simulating point cloud data. The data simulates various roof types including gable, pyramid, dome, and combined polyhedron shapes. In this study, a robust bottom-up method to segment surface patches was proposed for generating building models automatically by determining model key points of the objects. The results show that building roofs composed of the segmented patches could be modeled by appropriate mathematical functions and the model key points. Thus, 3D digitizing man made objects could be automated for digital mapping purpose.
