Purpose: This study was conducted in order to investigate the experiences of nurses in health care of women with multi-cultural background. The structure of these experiences was identified in a social-cultural context. Methods: Data were collected by means of in-depth interviews using tape-recordings from 16 participants who were providing childbirth care for culturally different women. A phenomenological method proposed by Colaizzi was used to guide the process of data analysis. Results: A total of 138 significant statements were extracted from the data resulting in nine themes and five theme clusters. Theme clusters that emerged from the data were: more in-depth cultural difference, difficulty in providing care in multi-cultured, sticking to care in our own way, not being ready to nurse, and accepting culturally different woman, such as a Korean woman. Conclusion: The findings suggest that systematic educational programs for enhancement of cultural competency and its support systems should be developed for Korean nurses. Useful materials on Korean childbirth care should also be provided to women giving birth.

Elementary school teachers' understandings about buoyancy were investigated through the questionnaire method. The questionnaire was composed of 4 questions on hydraulic pressure and 8 questions on buoyancy. The questions on buoyancy asked about the correlation of buoyancy with following basic concepts, density of liquid, volume of submerged object and so forth. 295 teachers on the 22 elementary schools in Busan, Yangsan and Gimhae were selected through random sampling method. The results of this study were summarized as follows: On the correlation of the magnitude and direction of hydraulic pressure with the depth of water, a large portion of the respondents had a scientific conception. But on the correlation of hydraulic pressure with density, the relatively small portion of them appeared to have a scientific conception. The respondents, on the whole, had a scientific conception about the correlation of buoyancy with density of liquid. But they seemed to have naive conceptions about the correlation of buoyancy with the volume of a submerged object and with the depth of water, the amount of water in container and the reduced amount of water by the object from container. We found that the respondents were context dependent and tended to search for solutions for the questions of buoyancy using the concept of pressure in the water. From above results, we suggested that in the would-be revised elementary science text book, the contents of pressure in the water should be introduced after the concept of weight in the water was gained.

These days, online media, such as blogospheres, online communities, and social networking sites, provides the uncountable user-generated content (UGC) to discover market intelligence and business insight with. The business has been interested in consumers, and constantly requires the approach to identify consumers' opinions and competitive advantage in the competing market. Analyzing consumers' opinion about oneself and rivals can help decision makers to gain in-depth and fine-grained understanding on the human and social behavioral dynamics underlying the competition. In order to accomplish the comparison study for rival products and companies, we attempted to do competitive analysis using text mining with online UGC for two popular and competing ramens, a market leader and a market follower, in the Korean instant noodle market. Furthermore, to overcome the lack of the Korean sentiment lexicon, we developed the domain specific sentiment dictionary of Korean texts. We gathered 19,386 pieces of blogs and forum messages, developed the Korean sentiment dictionary, and defined the taxonomy for categorization. In the context of our study, we employed sentiment analysis to present consumers' opinion and statistical analysis to demonstrate the differences between the competitors. Our results show that the sentiment portrayed by the text mining clearly differentiate the two rival noodles and convincingly confirm that one is a market leader and the other is a follower. In this regard, we expect this comparison can help business decision makers to understand rich in-depth competitive intelligence hidden in the social media.

This paper demonstrates the benefit of using MOOS-IvP in the development of control system for Unmanned Underwater Vehicles(UUV). The demand for autonomy in UUVs has significantly increased due to the complexity in missions to be performed. Furthermore, the increased number of sensors and actuators that are interconnected through a network has introduced a need for a middleware platform for UUVs. In this context, MOOS-IvP, which is an open source software architecture, has been developed by several researchers from MIT, Oxford University, and NUWC. The MOOS software is a communication middleware based on the publish-subscribe architecture allowing each application to communicate through a MOOS database. The IvP Helm, which is one of the MOOS modules, publishes vehicle commands using multi-objective optimization in order to implement autonomous decision making. This paper explores the benefit of MOOS-IvP in the development of control software for UUVs by using a case study with an auto depth control system based on self-organizing fuzzy logic control. The simulation results show that the design and verification of UUV control software based on MOOS-IvP can be carried out quickly and efficiently thanks to the reuse of source codes, modular-based architecture, and the high level of scalability.

The present investigation is to study the plane wave propagation and reflection of plane waves in a homogeneous transversely isotropic magnetothermoelastic medium with two temperature and rotation in the context of GN Type-II and Type-III (1993) theory of thermoelasticity. It is found that, for two dimensional assumed model, there exist three types of coupled longitudinal waves, namely quasi-longitudinal wave (QL), quasi-transverse wave (QTS) and quasi-thermal waves (QT). The different characteristics of waves like phase velocity, attenuation coefficients, specific loss and penetration depth are computed numerically and depicted graphically. The phenomenon of reflection coefficients due to quasi-waves at a plane stress free with thermally insulated boundary is investigated. The ratios of the linear algebraic equations. These amplitude ratios are used further to calculate the shares of different scattered waves in the energy of incident wave. The modulus of the amplitude and energy ratios with the angle of incidence are computed for a particular numerical model. The conservation of energy at the free surface is verified. The effect of energy dissipation and two temperatures on the energy ratios are depicted graphically and discussed. Some special cases of interest are also discussed.

Purpose: This study was conducted to understand the client relationship experience of the physical therapists working at elderly care facilities and to lay the foundation for finding the identity of physical therapists. Methods: In-depth interviews were conducted on eight incumbent physical therapists who had experienced working in elderly care facilities for at least one year. Data collection was conducted between June and September 2017, and the interview took an hour to an hour and a half to complete. After an in-depth interview, it was arranged as a file and analyzed according to the four steps of the phenomenological research method of the Giorgi. Results: Data were collected and analyzed; 19 categories, 6 themes and 5 domains were derived. Six themes were presented according to the 5 domains; the subject of relationships included 'diversity elderly'; context of relationships included 'the world of elderly nursing homes I did not know'; influence of relationships included 'the physical therapist is heartbroken because of the tormenting elderly'; condition of relationships included 'a reality that is tied to work'; aspects of relationships included 'how to reestablishing relationships with the elderly' and 'recognized and identified as a physical therapist'. Conclusion: This study shows that physical therapists working in elderly care facilities generally tend to fulfill their responsibilities and interact with clients; we found that identity of physical therapists was primarily defined by relationship experiences with patients.

Objectives : The purpose of this study is to explore the experiences of traditional korean medical doctors (TKMD) who have treated victims of sexual violence by collecting their qualitative data that cannot be obtained with statistical data. Methods : In-depth interviews were conducted with semi-structured questionnaires for each of 5 TKMDs who had experiences in treating sexual violence victims. For analysis, the interviews were recorded along with their facial expressions and actions during the interview process, and all collected data were analyzed by colaizzi's method. In each process, a 'phenomenological reduction' was applied. Results : The identity of TKMD's experience of treating sexual violence victims was structured into 25 themes, 9 theme clusters, and 4 categories. The 4 categories included 'Professionalism and sense of efficacy', 'Personal life experiences and mental trauma treatment experiences that are mutually influencing each other', 'Factors needed to increase TKMD's participation in treatment of sexual violence victims', 'Deriving the future strategy of traditional korean medicine'. Conclusions : This study derived the essence and meaning of TKMDs' experiences in treating sexual violence victims, and presented future directions of traditional korean medicine in this field. It is expected that the results of this study would be used as the basis for establishing the traditional korean medical support system for sexual violence victims in the context of the korean medical system.
