The design project of a technology product provides an opportunity for students to experience the inter-connectedness of academic information and ill-defined real-world problems. This study focuses on non-engineering students' activity and perception through the assistive technology design project. For this purpose, participants engaged in a team-based technology design project. Then, a qualitative research approach was adopted, which included reflective journals with 24 undergraduate students majored in Adaptive Physical Education. The analysis identified six factors (knowledge value, social value, reality value, accomplishment value, perspective value, benefit value) of perception and five stages (topic selection, function suggestion, visualization, presentation preparation, and presentation) of activity.

Purpose: The World Health Organization identifies spiritual care as a component of health and thus nursing care. There is a need to identify how self-esteem, communication and existential well-being affects spiritual care competence in nurses. Methods: The participants were 189 nurses in G metropolitan city. The survey was conducted from March 21 to April 8, 2016, with a self-report questionnaire. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, $Scheff{\acute{e}}$ test, Pearson correlation coefficient and stepwise multiple regression analysis using SPSS version 21.0. Results: Differences in spiritual care competence were statistically significant according to education level, work department, position, having received spiritual care education, experience of providing spiritual care, experience of asking religionist to provide spiritual care for a patient and recognition of need for spiritual care. The spiritual care competence of nurses showed a significantly positive correlation with self-esteem, communication and existential well-being. Factors influencing spiritual care competence were communication, experience of providing spiritual care and existential well-being which explained about 37.5% of spiritual care competence. Conclusion: It's necessary for nurses to develop intervention programs to strengthen spiritual care competence through improving communication, providing opportunities for spiritual care and existential well-being.

The augmented reality is the environment which consists of real-world view and information drawn by computer. Since the image which user can see through augmented reality device is a synthetic image composed by real-view and virtual image, it is important to make the virtual image generated by computer well harmonized with real-view image. In this paper, we present reviews of several works about computer vision and graphics methods which give user realistic augmented reality experience. To generate visually harmonized synthetic image which consists of a real and a virtual image, 3D geometry and environmental information such as lighting or material surface reflectivity should be known by the computer. There are lots of computer vision methods which aim to estimate those. We introduce some of the approaches related to acquiring geometric information, lighting environment and material surface properties using monocular or multi-view images. We expect that this paper gives reader's intuition of the computer vision methods for providing a realistic augmented reality experience.

Background: lung cancer (LC) is the fifth of the 10 leading causes of death in the world. LC is in first place for cancer-related mortality for both males and females in Taiwan. It is one of the most difficult cancers to treat and is often diagnosed at a late stage. Patients with stage IV are often unprepared for the diagnosis. Materials and Methods: To explore lived experience among patients newly diagnosed with lung adenocarcinoma stage IV within one year. Results: Twelve participants were recruited in this study. Content analysis of the interviews revealed four themes: (1) emotional roller coaster, (2) trying to find out causes, (3) adjusting my lifestyle, and (4) cancer fighter. Conclusions: This study provides new insight into the experiences of lung cancer patients y with newly diagnosed lung adenocarcinoma stage 4. These results will inform future supportive care service development and intervention research for patients with advanced stage cancer.

With the modern society approaching, a lot of new paradigms have been created which can be explained by the existing space notions while suspicions on the true essence and existence of space have been raised. Ontology regards as the beginning the cause for a 'Field' which will be faced for the research of the essence of a space where 'being-in-the-world' exists. This study has analyzed the existing method of space construction in the spatial thinking and works of Peter Zumthor who mentioning ontological viewpoint as the physiological background of his works so that the ontological spatial concept may be clarified. The following is the study results. First, in order to construct the structures of his own designing into a 'Field' for experiencing the existential meaning, Zumthor chose a reductive pattern with the entire additional elements removed. The materials leading the subjects to call attention to memory and experience and the methods dealing with it enables the realization of various spatial essences. Second, the ontological event-system is required for the formation of relationship among beings. He tried to create a spatial meaning by introducing external environment into the inside and using the materials reflecting regional features and phenomenological empiricism through the multisensory experience. Third, he applied assimilation/insert/adjustment/formative change as the way of constructing the relationship between site and structure.

Purpose: Lung cancer patients are often stigmatized since lung cancer is closely associated with smoking, which is a self-administered life style. The stigma of lung cancer has been examined in some qualitative studies; however, their findings were diverse and not yet synthesized. Therefore, this meta-synthesis study aimed to explore how lung cancer patients experience stigma. Methods: A meta-synthesis method, as suggested by Sandelowski and Barroso in 2007, was applied by aggregating the findings after an evaluation according to consolidated criteria for reporting qualitative research (COREQ). Results: By synthesizing the findings of the selected seven papers, a synthesized theme was emerged as "experiencing external and internal distances, which mandates authentic and consistent supports." The four sub-themes included 'experiencing some distance from the surrounded world,' 'experiencing self-made distance between the disease and oneself,' 'the disease experience causes social isolation and loneliness,' and 'there is lack of supportive care for myself.' Conclusion: Health care providers should be more attentive to supporting lung cancer patients by providing more effective advocacy programs that improve patients' quality of life.

Video streaming services make up a large proportion of Internet traffic on both fixed and mobile access throughout the world. Adaptive streaming allows for dynamical adaptation of the bitrate with varying network conditions, to guarantee the best user experience. Adaptive bitrate algorithms face a significant challenge in correctly estimating the throughput as it varies widely over time. In this paper, we first evaluate the throughput estimation techniques and show that the method that we have used offers stable response to throughput fluctuations while maintaining a stable playback buffer. Then, we propose an adaptive bitrate scheme that intelligently selects the video bitrates based on the estimated throughput and buffer occupancy. We show that the proposed scheme improves viewing experience by achieving a high video rate without taking unnecessary risks and by minimizing the frequency of changes in the video quality. Furthermore, we show that it offers a stable response to short-term fluctuations and responds swiftly to large fluctuations. We evaluate our algorithm for both constant bitrate (CBR) and variable bitrate (VBR) video content by taking into account the segment sizes and show that it significantly improves the quality of video streaming.

Purpose: The purpose of this study was to identify and describe phenomenological structures of the lived experience of struggling against an illness for patients with Amyotrophic Lateral Sclerosis (ALS). Methods: The participants were 7 patients with ALS recruited by snowball sampling who agreed to participate in this research and could verbally communicated with the researcher. Data were collected by long term-repeated interviews with participants in their own homes. Data were analyzed using Colaizzi's method of phenomenology. Results: Four categories were extracted as follows: 'Being seized with fear of death', 'Living a marginal life', 'Accepting hard fate', and 'Clinging to faint life'. Seven theme clusters were identified as: 'Wandering to find a healing method with ominous signs in the body', 'Having a diagnosis of ALS is like a bolt from the blue and struggling against illness with faint hope', 'Being forced out to the edge of life with anguish', 'Filling one's heart with hatred and longing toward becoming estranged from the world', 'Living with stigma as a stumbling block with bitter grief in one's heart', 'Accepting every things as one's fate with self controlled fear of death', and 'Attaching to desire to live'. Conclusion: The results of this study can be used to develop the programs to support patients with ALS and their family.

A game engine should have the architecture that can manage various interactions between entities in a game for offering users various game experience. For this purpose, the game engine architecture based on message system is used. But only by this message based system, it is difficult to change game world continuously according to some storylines. The reason of this is event-driven system like message based system is appropriate for processing individual message but is not appropriate for processing more bigger logical work unit. For this purpose this paper proposes the storyline entity. The storyline entity has logical flows for a storyline and is called by engine continuously. By this proposed game engine architecture he or she can maintain free game experience by message based system and can add some progressing of storylines.
