In this paper, I describe the importance of matrix spraying conditions in imaging mass spectrometry (IMS) to obtain successful imaging results. My developed matrix application methodology, which is a "two-step matrix application" sequentially combined with matrix sublimation and spraying matrix solution can provide high reproducibility and high ion yield compared with a conventional direct spraying method. However, insufficient IMS results were obtained occasionally despite the two-step method. Therefore, I wanted to characterize the methodology to continuously provide high quality data. According to my results, the sublimation time was not a strict parameter, and the most important step was the first spraying condition. This means that the extraction conditions from the tissue section and co-crystallization of the matrix were the most important factors.

Purpose: The purpose of this study was to explore and develop a deeper understanding of the experiences of mothers of premature children receiving rehabilitation therapy. Methods: The participants were 12 mothers with premature children who had received rehabilitation therapy for over 1 year. Individual in-depth interviews were conducted from July to August 2017. The data were analyzed through the phenomenological research method. Results: The participants' experience was structured into five thematic clusters: 'Regret and guilt that premature birth led to rehabilitation therapy', 'Burden of life in an endless tunnel', 'Changes in personal relationships surrounding me and my child', 'Meaning of new life through my child', and 'Desire to expand the rehabilitation of premature infants'. Conclusion: The results of this study will be helpful for developing family-centered care programs for premature infants at high risk of developmental disorders.

Purpose: The purpose of the study was to explore the experience of patients with facial burn injuries regarding their interpersonal relationships. Methods: The phenomenological research method was used. Participants of the study consisted of five males and three females. Data were collected through individual in-depth interviews from November, 2014 to February, 2015 and analyzed using Colaizzi's method. Results: Five theme clusters were extracted that described patients' experiences. They are "being a lonely foreigner," "closing my mind toward the world," "hiding hurt feelings," "companion of my face," and "communicating with the world". Conclusion: The results of this study provide a deep understanding and insight into the experience of interpersonal relationships among facial burn patients. The development of a comprehensive program including physical, psychological, and social aspects is recommended to address the problems facial burn patients encounter in interpersonal relationships and to facilitate interaction.

Background: While the application of procedural methods to solve the infertility problem has increased, the decline in the quality of life of women who experience infertility has been disregarded. Methods: This qualitative study used phenomenological analysis of data collected from 13 women with infertility in South Korea to reveal the subjective meaning of physical experiences perceived by women over the course of treatment. Results: Upon analyses of the treatment experiences of women with infertility in South Korea via a phenomenological analysis method, 10 themes were extracted and integrated into four theme clusters ("Perceiving infertility," "The body that gives birth," "A process in an endless tunnel," "Caring for my marginalized identity"). Conclusion: The results of this study suggest that women with infertility in South Korea perceived their own bodies as givers of birth living in traditional and patriarchal societies. A contextual flow proceeded to the final stage of women caring for their marginalized identity, which had suffered throughout the course of their infertility journey.

This study is to construct the simple estimating model for the HIC15 of the driver dummy using the frontal impact test results. Test results of 9 vehicles of Hyundai Sonata from the MY2002~MY2020 USNCAP are utilized for constructing the linear regression model. The average accelerations extracted from the vehicle crash pulses are handled as the main factors. The average accelerations of 10 ms interval within 0~100 ms are calculated from the crash pulse data of 9 vehicles. The present estimating model of the HIC15 using the average accelerations of 10 ms interval in the 0~80 ms range shows good agreement with the tested value within 2.4% maximum error.

We constructed the integrated management system of distributed astronomical data of Bohyunsan Optical Astronomy Observatory(BOAO), Sobaeksan Optical Astronomy Observatory (SOAO), and Mt. Lemmon Optical Astronomy Observatory(LOAO). The observed data was stored in the archive of the observatory and MySQL table is saved in the integrated management system. There are data archive managers in the observatories and they manage the integrated management system such as data storing, head information extraction, table generation, and management of web pages, etc. The users can search and download all the data in the integrated management system web page. The concept of this system - send queries from web page to the observatory archives - is the same of the basic concept of virtual observatory. This research is one of the main work in the Korean virtual observatory which is take part in the international virtual observatory alliance.

Purpose: The purpose of this study was to understand the choice experiences of students majoring in nursing and whose mothers were nurses. Methods: The participants of this study were 12 students, six male and six female. Data were collected via an in-depth personal interview. The collected data were analyzed with Colazzi's phenomenological methodology. Results: A core theme of 'Natural choice as my major' emerged. In addition, we found the following three theme clusters: 1. My choice; 2. Expanding relationship between Mother and I; 3. Journey with mother. Conclusion: The results of this study show that the mothers of nursing students who were nurses themselves were good role models. They could influence their children to choose nursing as a profession. Also, they affected or are affecting their children to be colleagues in the same way. If we could provide good working environments for nurses, the next generation will also choose nursing as a profession and ultimately establish a family line. An educational setting is required to provide better professional nursing conditions for the next generation.

The emergence of ubiquitous computing environment will change the service architecture of business information systems such as Decision Support System(DSS), which will be a new application. Recent mobile DSSs allow the decision makers to be benefited from web and mobile technology. However, they seldom refer to context data, which are useful for proactive decision support. Meanwhile, ubiquitous applications so far provide restricted personalization service using context and preference of the user, that is, they do not fully make use of decision making capabilities. Hence, this paper aims to describe how the decision making capability and context-aware computing are jointly used to establish ubiquitous applications. To do so, an amended DSS paradigm: CKDDM(Context-Knowledge-Dialogue-Data-Model) is proposed in this paper. What will be considered for the future decision support systems when we regard ubiquitous computing technology as an inevitable impact that enforces the change of the way of making decisions are described. Under the CKDDM paradigm, a framework of ubiquitous decision support systems(ubiDSS) is addressed with the description of the subsystems within. To show the feasibility of ubiDSS, a prototype system, CAMA-myOpt(Context-Aware Multi Agent System-My Optimization) has been implemented as an illustrative example system.

Purpose: This study was done to gain understanding of what career and related experience mean to individuals undergoing hemodialysis. Methods: Ten male patients receiving hemodialysis participated in the study. Data collection took place between November 18, 2008 and February 10, 2010, via unstructured interviews. Data collection and analysis were conducted simultaneously, and Colaizzi's phenomenological method (1978) was used for the analysis. Results: The significance the participants found in their "dual" life as worker and dialysis patients was classified into five categories: 'Recognition of self-existence value', 'My health comes before my work', 'Being afraid of stigma', 'Limitation of restricted work', and 'Difficulty with time management.' Conclusion: It was found that the dialysis patients showed ambivalent feelings towards their careers, hoping they will be able to continue to work yet fearing that the continued work might break balance the between their livelihood and healing. Therefore, it is recommended that hours for hemodialysis be more flexible to ensure that patients can keep their jobs and better manage their time while undergoing treatment.

In this paper, we propose a system that collects data from sensors that detect the sleeping environment and adjusts the sleeping environment optimally based on the environment to help you get a good night's sleep. The sleep environment analysis is based on the determination of the sleep stage by detection of twisting through the load cell. In addition, based on data such as temperature, humidity, and illuminance, heat devices, humidifiers, blinds, etc. are controlled to create an environment in which to have a good sleep. The sleep environment control according to the sleep state can reduce fatigue when waking up by inducing a sleep state that is easy to wake up.
