Rectangular dielectric waveguides, the most fundamental and indispensible elements in integrated optics, have been investigated by many researchers with various approaching methods including from the relatively approximate techniques to the numerical method. In this paper, the optimum equivalent waveguide model is adopted which is determined by a perturbation feedback process for analyzing the propagation constant by means of computer simulation, we have ascertained that the propagation constant from perturbation feedback method gives the best approximate value because it coincide with more exact value than obtained by other approximating methods. The technique also provides analytical expression for the modal field profile that should be useful in the design of various integrated optical devices.

It was investigated on the logical inter-relationship with plastic thinking systems in interior space constitution. Followings were produced the conclusion of study from the plastic thinking. First of all plastic thinking could be interpreted as the stage-oriented process from various approaching by intuitional, experimental techniques through the expansion of thinking capability with linguistic activities. And also interior space constitution could be extracted from the plastic language relating with design concept, could be extracted the design element by processing on the formation process based on material's physical properties. Next, space perception and constitution should be followed the massive perception between empty and full space based on the interrelationship. Additionally the constitution of interior space could be established through axis, integrated with detail functions. Interior space constitution could be accomplished on the study of material based on the characteristics of material, planned to coincide with the space's characteristics in selection for texture.

Wearable devices come in a variety of shapes and sizes in numerous fields in numerous fields and are available in various forms. They can be integrated into clothing, gloves, hats, glasses, and bags and used in healthcare, the medical field, and machine interfaces. These devices keep track individuals' biological and behavioral data to help with health communication and are often used for injury prevention. Those with hearing loss or impaired vision find it more difficult to recognize an approaching person or object; these sensing devices are particularly useful for such individuals, as they assist them with injury prevention by alerting them to the presence of people or objects in their immediate vicinity. Despite these obvious preventive benefits to developing Internet of Things based devices for the disabled, the development of these devices has been sluggish thus far. In particular, when compared with people without disabilities, people with hearing impairment have a much higher probability of averting danger when they are able to notice it in advance. However, research and development remain severely underfunded. In this study, we incorporated a wearable detection system, which uses an infrared proximity sensor, into a backpack. This system helps its users recognize when someone is approaching from behind through visual and tactile notification, even if they have difficulty hearing or seeing the objects in their surroundings. Furthermore, this backpack could help prevent accidents for all users, particularly those with visual or hearing impairments.

Purpose: This paper studied about the integration for management system of representative international standard related to sustainable development. The well-known International standards such as ISO 9001, ISO 14001 and OHSAS 18001 (ISO 45001) can be operated in accordance with the organizational situation individually, or in a variety of ways of integration. It can be applied to help organizations utilizing the newly established "ISO IEC Directive Part1 Annex SL", when integrating quality, environmental and safety & health management systems based on international standards. Methods: We conducted an empirical survey of management executives and experts to study how three factors (management systems, organizational capabilities and integration methods) could affect business performance. Results: The questionnaire was analyzed using AMOS structural equation model. Quality, environmental and safety and health management systems affected management performance, and integration methods of management system affected business efficiency, risk performance and financial performance. Integration method is also important because organizational competence affects various aspects of integrated management. However, factors that affect integration should also be considered in terms of organizational capabilities. This is because organizational capacity influences the integration plan. Conclusion: To integrate the document system at the strategic level, management should actively participate in integrated operations to integrate organizations, eliminate duplicate tasks, and foster document integration experts to reflect the characteristics of individual standard. In the case of document integration, quality management is focusing, but once ISO 45001 is issued, the use of Annex SL is increasing, and Quality, environment and safety & health integration will also be expanded. It is possible to increase the effect of integration by strategically approaching and establishing organization document system rather than simple integration according to management system standard arrangement.

As de-schooling students (students who leave schools) have been produced and increased in middle and high schools every year since 1990s, urban alternative schools have founded with Seoul as the center. The objects of such urban alternative schools are de-schooling teenagers, and their educational goal is to make the students to discover their own values and grow as members of the community by accomplishing their healing and growth. Most of students in alternative schools have excessive self-centered feeling than ordinary people, and since they don't have exchanges with others, they have to receive holistic healing along with education. Here, 'healing' is a method of approaching to health through environmental, psychological, social and cultural supports unlike 'treatment' used for medical means. Therefore, holistic healing for alternative schools' students has to accomplish self-knowledge, self-control, and self-healing without repulsion through spaces of healing environments instead of heavy-handed exchanges. This study has integrated a theory of Max $L{\ddot{u}}scher$ who suggested a psychological healing theory in terms of internal character and a theory of Rudolf Steiner who suggested it in terms of practical and holistic sense and analyzed Sungmisan School, one of urban alternative schools in Seoul through the integrated theory. The analysis of the integrated theory are intended to emphasize the importance of healing environments and suggest methods in creating healing environments for urban alternative schools in the future.

In these days it can be said that knowledge based society has been passed through and creative society is approaching, and the important keywords to the coming creative society should be the knowledge, the creativity, and the convergence. In order to make preemptive responses to this 21 century's new creative society, cultivation of gifted students with integrated prototype is also an imperative reason to prepare. With this historical background Korean Ministry of Education, Science, and Technology announced "a general plan on invigoration of elementary and middle school level art education for cultivation of creativeness and humanity" containing the acting curriculums of science and art integrated on June 2010, and also announced "the second general plan for support on development of science and technology professionals" including STEAM education for elementary and middle school level at January 2011. In this paper we developed a strategy appliable to establish an education institution for gifted students specialized on promoting the students to the convergence type gifted students. For the purpose, we derived the necessity for convergence education for the gifted and the implication points through analysis on the examples, and developed a strategy to establish an education institution for gifted students.

Nursing is indeed a practice discipline with experiential learning in clinical practice areas comprising an overwhelming portion of a Nursing Student's education. The statement is used to provide a basis for discussion of some issues involved in relation to clinical nursing education. However the lack of substantial research in the area of clinical nursing education would suggest that this 'heart' of the nursing student's professional education has olng been ignored. The purpose of this study is to critically review and analysis then suggest effective approaches of clinical nursing education. First. the curriculum can be developed by faculty consistently. Curriculum design begins with the writing of philosophy and the selection of objectives for the program. The philosophy must include a statement of beliefs and intrinc values about human being. nursing and teaching learning process. Second. faculty practice can be narrowed practice-theory gaps. Third. clinical teaching strategies can be used many different methods in order to facilitate development of clinical judgement and decision making. Fourth, clinical teacher's rols can influence student's learning attitude and intrinsic value; relating to students as mature individuals; creating an atomosphere where in the student felt comfortable approaching the instructor; providing support crisis situations. Fifth. clinical nursing evaluation can be developed the integrated models.
