  • Tapes are usually used in violent crimes and may contain important evidence. Separating adhesive side should be preceded to collect these evidence. In this study, we researched a novel dual-purpose reagent that can separate the tape without damaging and develop the fingerprints on porous surface when the tape is attached to A4 paper. As a result, the reagent of 1:2 ratio of 1,2-IND stock solution and HFE-7100 can separate without damaging the adhesive surface and develop fingerprints on separated A4 paper.

  • The purpose of this study is to understand the structure of mothers of mentally handicapped daughters' lived experience, to apprehend the connectedness of the structure of the experience with concept of Parse's human becoming theory, and to provide a foundation for nursing research and education. Data collection was conducted from October 1995 to April 1996. Research participants were eight mothers of mentally handicapped daughters whose ages ranged from 12 to 18 attending special schools located in either Inchon or Seoul. The researcher had interviews with them over their lived experience conducted tape recorded, and made an analysis according to Parse's “human becoming research methodoloy.” The data were collected using the dialogical engagement process “I and You,” the participant researcher and the participant subject. The data were analyzed using the extraction-synthesis and heuristic interpretation. The structural integration is illustrated in the following : 1) Realizing the mother's role of mentally handicapped daughters and admitting situation. 2) Concealing a part of their relationship with others is interpreted as revealing-concealing. 3) Living a life kept moving between separating and connecting. 4) Their flight back voluntarily to improve the situation is interpreted as powering. The conceptual integration which emerged was the lived experience of mothers is powering through the revealing-concealing and connecting-separating of valuing.

  • Purpose: The purpose of this study was to understand the meaning and nature of pain experienced among patients with chronic pain. The present study adopted a hermeneutic phenomenological method which was developed by van Manen. Method: The participants for this study were 4 men and 5 women, who were over the age of 20 with chronic pain more than 6 months. Data was collected by using in-depth interviews and observations from September, 2004 to December, 2004. The contents of the interviews were tape-recorded with the consent of the subject. Result: The essential themes that fit into the context of the 4 existential grounds of body, time, space and other people were 'untamed and unremitting pain', 'the body as an obstacle', 'continuity of suffering time as if the moment would never end', 'a narrow radial range of action' and 'separating from other people'. Conclusion: Patients with chronic pain experienced and perceived the world through the filter of their pain. It is necessary for nurses to understand the experiences of chronic pain patients and to provide more empathic, supportive care. Further research is needed on nursing interventions that could help chronic patients cope with and find the meaning in their suffering.

  • For commercialization of molten carbonate fuel cell (MCFC), it has some problems to be overcome such as decrease of porosity and thickness of the anode under the operating condition (at $650^{\circ}C$ and working pressure of more than 2 $kg_f/cm^2$). Recently, Ni-Al alloy anode has been proposed to replace the conventional Ni-Cr anode as an alternative material to resist a creep and inhibit the sintering. The objective of this research is to sinter the green sheet of Ni-Al alloy anode during single cell pre-treatment process, which has several advantages like cost down and simplification of manufacturing process. However, the Ni-Al alloy anode prepared with a conventional pre-treatment process showed the phase separation of Ni-Al alloy and formation of micropore(${\leqq}0.4{\mu}m$), resulting in low creep resistance and high electrolyte re-distribution. In order to prevent the Ni-Al alloy anode from phase-separating, nitrogen gas was used in the process of pre-treatment. Introducing the nitrogen, the phase separation from Ni-Al alloy into nickel and alumina was minimized and increased creep resistance. However, there was some micropore formation on the surface of Ni-Al alloy anode during the cell operation due to creation of lithium aluminate. Addition of more amount of electrolyte into a cell, especially at cathode, made the cell performance stable for 2,000 hrs. Consequently, it was possible to make the Ni-Al alloy anode with good creep resistance by the modified in-situ sintering technique.
