Purpose: This study, using the International Classification for Nursing Practice, aimed to identify the phenomenon of family nursing care, and the factors affecting it, for high-risk and frail older persons who have a significant need for home healthcare services. Methods: This study was conducted using secondary data collected by students who interviewed 93 healthcare subjects in a health center. The data was used to analyze the general characteristics, health-related characteristics, and confirmed problems of family nursing phenomena of the subjects. Independant t-test, Pearson correlation coefficient, and multiple linear regression were used for the data analysis. Results: The mean age of the subjects was 82.4±6.3 years. The most common problem of the family nursing phenomenon were unhealthy lifestyle, disturbance in family communication, and lack of family interaction in the community. People with greater family nursing phenomenon problems reported a higher degree of frailty and depression, lower quality of life and self-rated health. The factors that influence the family nursing phenomenon of frail older persons are the problems of mobility and hearing. Conclusion: Physical and psychological problems associated with aging can cause not only personal, but family functional problems as well. Therefore, a comprehensive family-oriented support program is required.

Purpose: This study was a qualitative study to explore and understand the adaptation experiences of hemodialysis among women with End-Stage Renal Disease (ESRD) and to develop a substantive theory using the grounded theory method. Methods: Participants were 15 female patients who underwent hemodialysis for ESRD treatment from three general hospitals. The data were collected through in-depth individual interviews. Results: The adaptation experience of participants was emerged as a process of taking care and enduring. There were four adaptation stages as a negative, despair, receptive, and maintenance period in reference to hemodialysis. The causal conditions were a vague expectations of recovery and refusal to undergo hemodialysis. The core phenomenon was that of confinement to dialysis machine. The contextual conditions for this phenomenon were the loss of femininity. They used action/interaction strategies such as transition their life with a focus on hemodialysis, seeking information, and learning how to take care of their body. Through this process, they had a strong will to live or had sustained their life. Conclusion: These results indicate that there is a need for nurses to understand the different steps of adaptation experiences of the given patient population. It is necessary for nurses to support them to lead their life as much normal as possible and improve the adaptation experience of ESRD.

The fatigue phenomenon, which is induced by stress accumulation due to the repeated loading of vehicles in the long term, is one of the main factors of the span of life of a steel bridge. In this paper, the effects of traffic properties on the fatigue life of ordinary short- and medium-span steel plate girder bridges that are exposed to relatively large dynamic effects are investigated. From the analysis, it was known that the fatigue life of the bridge becomes shorter with increasing traffic volume and number of large vehicles, and is affected by the weights of the vehicles. Based on the analysis results, a new parameter that can represent the traffic property that affects the fatigue life of the subject bridge is suggested, and the validity of the parameter is confirmed.

Organic light emitting diode(OLED) has been developed fast from 1963 when electric light emitting phenomenon was discovered. PMOLED(passive matrix OLED) is producted earlier than AMOLED(active matrix OLED). PMOLED is mainly mounted at sub display, but AMOLED is mounted at main display. Nowadays AMOLED is expanded to PMP(portable multimedia players), navigation and TV market. Even thought OLED's market is opening to many applications, OLED's life is worried until now. If we know about OLED's real life, we need time to test so much time over 20,000hrs. Realistically, there is difficult to test such as long time with products from the information-technology sector having a short life cycle. In this paper, we study about OLED's accelerated test to reduce life test by current. We can design OLED's accelerated life model by the result of test. The model consists of design variables like ratio of light emitting, organic material structure, condition of aging, etc. In conclusion, this model can be applied to study about organic material, machine and manufacturing process etc, and also it's possible to develop a method of manufacturing process & materials, so we need to study on the subject of this paper continuously.

The typical life cycle of filamentous fungi commonly involves asexual sporulation after vegetative growth in response to environmental factors. The production of asexual spores is critical in the life cycle of most filamentous fungi. Normally, conidia are produced from vegetative hyphae (termed mycelia). However, fungal species subjected to stress conditions exhibit an extremely simplified asexual life cycle, in which the conidia that germinate directly generate further conidia, without forming mycelia. This phenomenon has been termed as microcycle conidiation, and to date has been reported in more than 100 fungal species. In this review, first, we present the morphological properties of fungi during microcycle conidiation, and divide microcycle conidiation into four simple categories, even though fungal species exhibit a wide variety of morphological differences during microcycle conidiogenesis. Second, we describe the factors that influence microcycle conidiation in various fungal species, and present recent genetic studies that have identified the genes responsible for this process. Finally, we discuss the biological meaning and application of microcycle conidiation.

This paper presents that what's the right EOLL(End of Lamp Life) phenomenon on fluorescent lamp and how to detect it according to the lamp status. In normal end of life situation for fluorescent lamps is emitter depletion of the cathodes. So, in most cases, the discharge will extinguish and the lamp will not start. But if the ballast is capable of sustaining the discharge, a new condition arise. Especially, the T4 and T5 lamp which has a short distance from cathode to socket of lamp future must have the EOLL Protection function.
