This descriptive investigation aims to identify a relationship between QOL, depression, and anxiety in hemodialysis patients. I conducted this research on 130 subjects aged 19 or above who have received dialysis for at least one month in the hemodialysis unit at N hospital in the city of S. However, it came to 112 as I took out those who either quit, died, or filled out a questionnaire in the incorrect manner. In regards to average points of QOL on a 100-point scale, it is 57.77, demonstrating quite low QOL. Concerning average points of depression and anxiety, it is 12.25 and 10.52, respectively, showing quite a high figure. With regard to a correlation, there is a significant correlation between the three factors in hemodialysis patients: there is a negative correlation between QOL and depression (r=-.782, p<.001); a negative correlation between QOL and anxiety (r=-.719, p<.001); and a positive correlation between depression and anxiety (r=.873, p<.001). The outcome of multiple regression analysis on factors affecting QOL shows that depression is the element influencing QOL (β=-.585). Therefore, this study is significant in providing basic data for establishing intervention strategies aiming to reduce levels of depression which has the strongest impact on QOL in the patients and for developing a nursing intervention program intending to improve their QOL.

The purpose of this study is to analyze the garden details of Carla Scarpa in order to understand his selection and composition of materials, detailing style and symbolism of the spaces. Literature review and a field trip were conducted for the study and the results are as follows. First, Scarpa used vernacular materials such as Murano glass and Istrian limestone, and juxtaposed various materials using contrast of color and texture. His mixed uses of traditional and modern materials shows the passage of time. Second, he create his own detail style such as ziggurat and geometric motif, which make the garden space to look more interesting and rich. Scarpa respected local craftsmanship like glass design and used textile design style such as overlaying. Third, symbolic uses of water features help make narrative and poetic gardens. Scarpa's unique detail style and respects for traditional craftsmanship provide lessons on how to interpretate traditional design style in modern garden.

This study examined pruritus to provide the data based on burn patient pruritus. A self-report questionnaire survey was conducted among ninety five burn survivors, who were over 18 years of age with admission periods longer than two weeks. The results indicated that the average burn range was $18.95{\pm}17.10%$, severity was $48.83{\pm}23.96$, and distress was $46.42{\pm}25.80$. A significant difference in pruritus consequences was observed according to frequency. The patients consistently experienced pruritus, even if it happened less often, difficulty in falling asleep (F=4.817, p=.004), poor mood (F= 5.955, p=.015)), and loss of concentration (F=6.483, p<.000). A significant difference in the pruritus consequences according to duration was observed, lasting for 30 minutes for all groups, more than the population and less than 30 minutes, difficulty in falling asleep (F=7.452, p<.000), poor mood (F=3.655, p<.015), and loss of concentration (F=12.564, p<.000). The frequency, duration (r=.29, p=.004), severity (r=.45, p<.000), distress (r=.44, p<.000), and consequences of pruritus in burn patients (r=.29, p=.004) showed a positive correlation. The results of this study could be used as a base material for the care of burn patients experiencing pruritus.

This study was to investigate the factors influencing job satisfaction of nurses in long-term care hospitals focusing on burnout and burden. The participants were 206 nurses recruited from long-term care hospitals in B metropolitan city and C city. Data were collected from January to March, 2014 and analyzed using SPSS WIN 18.0 program. The frequency of experience was $1.65{\pm}0.42$, which is 4~5 times per month and once or twice per week in the problematic behavior in dementia. The frequency of burden was $1.46{\pm}0.48$, which means one nurse can solve the problematic behaviors in dementia. Burnout was $2.53{\pm}0.61$, and job satisfaction was $2.87{\pm}0.45$. Negative correlations were found between burden and job satisfaction (r=-.256, p=.003), and between burnout and job satisfaction (r=-.718, p<.001). A factor influencing job satisfaction was burnout (${\beta}$=-.735), which explained 57%. It is suggested that Intervention programs should be developed to reduce burnout and burden, and to increase job satisfaction for nurses.

Nursing service quality can vary depending on the work attitude and behavior of nurses. Nursing attitude and behavior that can be described as voluntary and proactive organizational citizenship behavior(OCB). OCB affects the work performance of nurses in clinical practice is very important and organizational justice is an important influencing factors of OCB. The purpose of this study was to determine the influential factors of organizational justice on OCB of nurses. The descriptive-correlational method was applied. The study was carried out less than a 500-bed hospital. Participants of the study included 230 nurses working in secondary hospitals. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and multiple regression with the 18.0 SPSS/Window program. Considering the components of organizational justice, there was a significant positive correlation(r=.172~.540, p=.000) between OCB and distributive, procedural and interactional justice. Also, Total organizational justice explained 29.1% of total OCB with influencing factor (${\beta}$=.540) and was statistically significant(F=93.777, p=.000). The influencing factors to OCB were distributive justice(${\beta}$=.283) and interactional justice(${\beta}$=.249) except procedural justice. The findings suggest that strategies of nursing management are needed to focus on distributive justice for compensation and interactional justice for social relationship in order to induce nurses' organizational citizenship behavior.

Recently, the medical education is undergoing system transition from a medical college to a medical graduate school and introduction of performance test in the doctor license state examination. Therefore, To deal with these challenges, it is needed that medical faculty prepare the education programs for considering student's personal characteristics and improving Clinical performance. So, The purpose of this study was to understand relation among Stress, ego-resilience, self-efficacy and Clinical performance in graduate medical student, and for this study, We conducted a survey of 97 medical graduate school students in D city during the period from August 19st to 20st. 2011. The study found a negative correlation between Stress and Ego-Resilience, a positive correlation of stress with confidence at low region in Self-Efficacy. Ego-Resilience correlates positively with CPX at low region in Clinical performance, Preference for difficulty level of the task at low region in Self-Efficacy correlates negatively with OSCE. OSCE and CPX at low region in Clinical performance are positively correlated. Therefore, Stress reduction of students can improve Self-Efficacy, Furthermore, improve ultimately Clinical performance. According to this study, To improve Clinical performance competence, student's personal characteristics should be considered and education programs for self-efficacy and ego-resilience advancement be reflected in curriculum.

Medical treatment for animals is very difficult as the opinions of pets' masters take priority over treatment regardless of the seriousness of pets' disease or the needs of medical treatment. In case that a pet has heart disease, especially, it is difficult to get the direct answer from the pet's master on the decision or confirmation of treatment. For those reasons, it is almost impossible to predict and treat the pet before an emergency like the heart failure or an unexpected death happens. Using stethoscope can be the first diagnosis method to check the heart or any kinds of disease inside the body. High-tech equipments like CT, X-ray or Ultrasound can be used, but they can only be used as a second choice of diagnosis method since it requires professional skills and its high price. That's why stethoscope is still the best diagnostic tool when one makes the first diagnosis. In this study, we give a detailed account of digital diagnosis system in which veterinarians can analyze the sound from stethoscope without bringing it to their ears and make a diagnosis wherever they are. And we suggest a new concept of diagnosis system surrounding, which shows the relativeness of disease through Level Crossing Rate(LCR) and energy level from the stethoscope sound made in this system.

This paper describes an Adaptive Context-aware Service (ACS) using Model Driven Architecture (MDA)-based Service Creation Environment (SCE) on PARLAY X based service delivery platform in ubiquitous computing environments. It can be expected that both the context-awareness and adaptation in ubiquitous computing environments will be deployed. But the existing context-aware middleware lacks in considering adaptation. Therefore, the object of this paper is to support the architecture and the Application Programming Interface (API) of the network service for both the context-awareness and adaptation in ubiquitous computing environment. ACS is to provide users with the adaptive network service to the changing context constraints as well as detecting the changing context. For instance, ACS can provide users with QoS in network according to the detected context, after detecting the context such as location and speed. The architecture of ACS is comprised of a Service Creation Environment (SCE), Adaptive Context Broker and PARLAY gateway. SCE is to use Context-based Constraint Language (CCL) for an expression of context-awareness and adaptation. Adaptive Context Broker is to make a role of the broker between SCE and PARLAY G/W. PARLAY G/W is to support API for PARLAY X-based service delivery platform.

Recently, as the number of Internet users are growing explosively, e-learning has been applied spread, as well as remote evaluation of intellectual capacity However, only the multiple choice and/or the objective tests have been applied to the e-learning, because of difficulty of natural language processing. For the intelligent marking of short-essay typed answer papers with rapidness and fairness, this work utilize heterogenous linguistic knowledges. Firstly, we construct the semantic kernel from un tagged corpus. Then the answer papers of students and instructors are transformed into the vector form. Finally, we evaluate the similarity between the papers by using the semantic kernel and decide whether the answer paper is correct or not, based on the similarity values. For the construction of the semantic kernel, we used latent semantic analysis based on the vector space model. Further we try to reduce the problem of information shortage, by integrating Korean Word Net. For the construction of the semantic kernel we collected 38,727 newspaper articles and extracted 75,175 indexed terms. In the experiment, about 0.894 correlation coefficient value, between the marking results from this system and the human instructors, was acquired.

This study aims to analyze the characteristics of reflective thoughts of students during experiments in general physics experiments. The participants were 32 college students, they submitted 10 experiment reports including answers to questions for reflective thinking. The results were as follows: First, students show reflective thinking broadly in the experiment, levels were followed by practical reflection, technical reflection, and critical reflection. Also, they actively accepted the knowledge related to experiments, but were passive in connecting new knowledge and experiences obtained through the experiments or forming new questions. Second, the reflective thinking of students show high correlation with experiments related to prior knowledge or the easy-to-understand process. Third, through the qualitative analysis of open-ended questions, it was confirmed that technical reflection occurs in individual evaluation, practical reflection in group evaluation, and practical reflection and critical reflection in improvement proposal. While the students' reflective thinking were superficial or mainly functional, however, they recursively examined the learning contents and the experimental process concurrently.
