In this paper, we implemented a system to detect dangerous situations by recognizing the dangerous elements for infants by reading 2D images of children's houses, parks, playgrounds, and living rooms where infants are present through Faster R-CNN. We have implemented a detection model based on data that can be easily obtained from real life. Currently, machine learning is commercialized based on speech recognition and behavior data. However, this model can be applied to various service fields Respectively.

The aims of this study are to analyze and compare the elementary textbook contents of science in Korea, USA and England and to make suggestions for the improvement of integrative contents in Korean science textbooks. For this study, lessons on living things in the three grade science textbooks of three different countries were selected and analyzed according to the five criteria: component elements of the lesson, integration of knowledges and investigations, integration of subject and life, connection with other subjects and focus of integration. From this comparative study, five suggestions are inferred for the improvement of the Korean elementary science textbooks. First, it is recommended that Korean textbooks should present unit objectives and evaluative components in the introductive part and last part of each lesson. Second, Korean textbooks should include scientific knowledges as a way of presenting educational contents. Third, Korean textbooks are recommended to include integrated contents fitting for students' life context. Fourth, Korean textbooks are recommended to integrate contents in connection with mathematics, arts, literature and so on. Fifth, issues which can facilitate students to understand contents in the textbooks and to relate to their life should be more employed.

Post-modern society leads us to accept diversity and variability instead of pursuit of the absolute truth, beauty or classical value systems, thus leading to hybrid phenomena. The purpose of this study is to analyze characteristics and expressive effects of hybrid expressions through which to provide conceptual bases for interpreting expanded meanings of fashion illustrations that express aesthetic concepts of hybrid culture. Hybrid refers to a condition on which diverse elements are mixed with each other, so any one element can not dominate others. It is often used to create something unique and new by a combination of unprecedented things. Hybrid can be classified into four categories: temporal hybrid, spatial hybrid, morphological hybrid and hybrid of different genres. Temporal hybrid from a combination of past and present in fashion illustration includes temporal blending by repetition and juxtaposition. Spatial hybrid shows itself in the form of inter-penetration and interrelationship by means of projection, overlapping, juxtaposition and multiple space. Morphological hybrid expresses itself through combination of heterogenous forms and restructuring of deformed forms. Hybrid of different genres in fashion illustration applies various graphic elements or photos within the space, and represents blending of arts and daily living. Such hybrid expressions in fashion illustrations reflect the phenomena of diversity and variability of post-modern society. Hybrid expressions in fashion illustrations predict endless possibility of expressing new images through combining various forms or casual elements and can develop toward a new creative technique.

The considerable increase of the elderly with dementia is expected annually and when we think about the family members' and the patients' suffering, it could be painful. Above all things, it imposes heavy economic burdens on the family members that have patients who suffer from diseases of age like dementia or paralysis that caring them at home and also, it is not desirable for those old people in point of physical or environmental circumstances for medical care. Thus, it is needed urgently that the expansion of specified facilities and improvement of services for these old people. Under this present condition, it is the special feature that the subject of research is people/facilities that offer services, not the elderly with dementia-the main user of those facilities. Thus, it is the time that we need various accessing plans that can grasp the patiences' activities and specialties and solve these problems in view of designing interior space. So, I tried to make designs that manage the elderly with dementia effectively and adequate to run facilities with considerations on the state of domestic specialized long-term care facilities for the elderly with dementia and researched guiding principles on physical healing surroundings with analysis that focused on the patients' activities, especially.

Despite rapid technological advance and increased automation facilities, many jobs and activities in our living require manual materials handling(MMH). These include wide variety of activities such as moving things, lifting bags. boxes or cartons, etc. Many studies found that handle could affect on maximum acceptable weight of lifting, but there were few studies f3r the effects of work posture and coupling in lifting tote box. This study performed that ten male college students were required to lift a tote box with and without handle for three postures (bending, straight, right angle posture). From the experiment, following results were obtained. (1) MVC reduced maximum 23% by type of handle. (2) MVC was highest in straight posture, but was lowest in right angle posture. (3) As a result of ANOVA, MVC paid attention to posture and coupling. (p<0.01) (4) To all handle types, biceps brachii activity was increased in right angle posture. but reduced in straight posture. (5) To all posture, biceps brachii activity was most lively in no handle. The results of MVC measurement, subjective rating, EMG analysis, statistic analysis showed that maximum acceptable weight of lifting was influenced by type of handle and straight posture was more comfortable than other postures. Based on these results, it was concluded that acceptable weight of lifting has to differ for work posture and coupling.

Because of various stresses with rapid change of social structure, the number of the disabled increase steadily. So, the interest of touch garden which the disabled interact with nature and communicate with the non-disabled is more in demand. This study carried out a survey for landuse, facilities, therapeutic garden in creating touch gardens targeting the disabled using them. The results are as follows: At first, the appropriate natural facilities can lead return visit of the disabled. The second, general facilities for information and barrier-free are insufficient. The third, the disabled demand more places for sense of touch and vision, and, also they demand more places for feeling various living things and sense of the season. And the last, the disabled have no experience in therapeutic gardens, but they have consensus for creating special places for the disabled. This study carried out a survey for specially designated user such as the disabled, but through it, it is expected to establish developed design guidelines for creating touch gardens and therapeutic gardens.

As public acceptance of nuclear energy in Korea worsens due to the Fukushima accident and the earthquakes that occurred in the Gyeongju area near the Wolsong nuclear power plant (NPP), estimating the effects of earthquakes has become more essential for the nuclear industry. Currently, most countermeasures against earthquakes are limited to large-scale disasters. Minor-scale earthquakes used to be ignored. Even though people do not feel the shaking due to minor earthquakes and minor earthquakes incur little damage to NPPs, they can change the environmental conditions, for instance, underground water level and the conductivity of the groundwater. This study conducted a questionnaire survey of residents living in the vicinity of an NPP to determine their perception and acceptance of plant safety against minor earthquakes. The results show that the residents feel earthquakes at levels that can be felt by people, but incur little damage to NPPs, as minor earthquakes (magnitude of 2.0-3.9) and set this level as a standard for countermeasures. Even if a minor earthquake has little impact on the safety of an NPP, there is still a possibility that public opinion will get worse. This study provides analysis results about problems of earthquake measures of Korean NPPs and specific things that can bring about an effect of deterioration of public acceptance. Based on these data, this article suggests that active management of minor earthquakes is necessary for the sustainability of nuclear energy.

Today, we are living in the era of data and information. With the advent of Internet of Things (IoT), the popularity of social networking sites, and the development of mobile devices, a large amount of data is being produced in diverse areas. The collection of such data generated in various area is called big data. As the importance of big data grows, there has been a growing need to share big data containing information regarding an individual entity. As big data contains sensitive information about individuals, directly releasing it for public use may violate existing privacy requirements. Thus, privacy-preserving data publishing (PPDP) has been actively studied to share big data containing personal information for public use, while preserving the privacy of the individual. K-anonymity, which is the most popular method in the area of PPDP, transforms each record in a table such that at least k records have the same values for the given quasi-identifier attributes, and thus each record is indistinguishable from other records in the same class. As the size of big data continuously getting larger, there is a growing demand for the method which can efficiently anonymize vast amount of dta. Thus, in this paper, we develop an efficient k-anonymity method by using Spark distributed framework. Experimental results show that, through the developed method, significant gains in processing time can be achieved.

Purpose: This study was done to explore the lived experiences in older Korean women with early stage of Parkinson's disease. The research question was "What is the meaning and nature of the older women's experiences who were diagnosed with Parkinson's disease?" Methods: In this study, we adopted van Manen's hermeneutic phenomenological approach to find the lived experiences of older women diagnosed with Parkinson's disease. Six older women diagnosed with Parkinson's disease within five years participated, and data were collected through in-depth interviews. Results: Five fundamental lifeworld themes and seven subthemes emerged from the data. The first theme of corporeality had three subthemes: 'being shocked by an unexpected diagnosis', 'fewer things can be done due to the illness' and 'lost my prettiness'. The second theme representing relationality was 'hiding the illness because of others' whispering'. The temporality theme was 'fear of symptom aggravation'. The spatiality theme was 'being placed in a blind spot of information'. The last existential theme of material had 'obsession with drugs'. Conclusion: The results of this study provide an in-depth understanding of older womens experiences of living with Parkinson's disease. The findings can help develop interventions specific to these group of women to provide sufficient emotional support and accurate information.
