  • Purpose: In this study, the articles which developed and applied nursing interventions for patients with cancer were reviewed and analyzed. Methods: The analysis was performed in light of 171 pieces of literature on nursing interventions for patients with cancer published between 1991 and 2010. Results: Approximately half of the studies have been published between 2006 and 2010. The quasi-experimental designs using nonequivalent control group and no-synchronized design were the most common form of research design among the 71 papers constituting 41.52% of the total. The most commonly used nursing intervention was education (25.2%), followed by massage (20.4%) and exercise (11.5%). The most common outcome variable was anxiety (11.8%), followed by pain (8.0%) and nausea and vomiting (7.3%). Conclusion: The results of this study can provide useful information for the development of nursing interventions in specialized areas. Systematic literature review or meta-analysis is needed in this area.

  • The interaction between ionic surfactants and different nonionic molecules and polymers are studied using ion surfactant selective electrode. From the experimental data, critical concentrations of the interaction and binding process are evaluated. The interaction between hexadecyltrimethylammonium bromide (HTAB) with polyethylene glycol (PEG) in three molecular weights (1000, 10000 and 100000) and also schiff-bases, 2-[2-carboxyphenyl nitrilomethylidyne]-phenol (ortho CNP), 2-[3-carboxyphenyl nitrilomethylidyne]-phenol (meta CNP)and 2-[4-carboxyphenyl nitrilomethylidyne]-phenol (para CNP) with the potentiometric method were investigated using HTAB membrane selective electrode. In the case of PEG with increasing molecular weights more interaction to HTAB occurs. The electromotive force (EMF) data also showed that interaction between para CNP with HTAB is more than the other schiff-bases. It seems this case related to less space interference of COOH group for that compound. The onset of binding ($T_1$) of course is the same for three schiffbase molecules.

  • 춘천 지역 구봉산층군 내에서 산출되는 백색 및 흑회색 투감섬석에 대하여 전자현미분석과 리트벨트법에 의하여 결정화학적 특징이 연구되었다. 화학 조성상 백색 투감섬석 (WHT)은 흑회색형 (BLT)에 비하여 Al과 Na의 양은 많고, Mg와 Ca의 양은 적은 차이를 보여준다. 단위포의 크기에 있어 b축의 길이는 WHT가 BLT보다 약 0.013$\AA$ 크다. 이는 후자의 M(4) 자리에 보다 많은 Na와 Mg가 치환된 결과로서 계사된 $\AA$로 잘 일치하고 있다. 자리 점유율에 있어 BLT의 경우 모든 Al이 T(2)에 채워지며, WHT에서는 T(1), T(2)에 각각 0.138, 0.181씩 Si를 치환하고 있다. M(1), M(2), 및 M(3)는 모두 Mg에 의해 채워지고 있으며, Ca가 채워지는 M(4)에는 BLT에서는 소량의 Mg가 들어 있다. (001) 방향으로 투각섬석의 구조를 작도해 보면, WHT에서는 사면체의 바닥면이 T(1) 안쪽으로 다소 기울어져 있으나, BLT에서는 T(1)과 T(2)가 서로 마주보며 기울어져 있는 특이한 양상을 보여준다. 이러한 구조상의 차이점은 앞으로 보다 많은 투각섬석에 대한 구조적인 연구를 수행할 필요가 있음을 보여준다.

  • The main challenge in many applications of acetic acid is acid dehydration and its recovery from wastewater streams. Therefore, the performance of polyamide thin film composite is evaluated to separate acetic acid from water. To reach this goal, the formation of polyamide layer on polysulfone support membrane was investigated via interfacial polymerization (IP) of meta-phenylenediamine (MPD) in water with trimesoyl chloride (TMC) in hexane. Also, the effect of synthesis conditions, such as concentration of monomers and curing temperature on separation of acetic acid from water were investigated by reverse osmosis process. Moreover, the separation mechanism was discussed. The solute permeation was carried out under applied pressure of 5 bar at $25^{\circ}C$. Surface properties of TFC membrane were characterized by ATR-FTIR, SEM and AFM. The performance test indicated that 3.5 wt% of MPD, 0.35 wt% of TMC and curing temperature of $75^{\circ}C$ are the optimum conditions. Moreover, the permeate flux was $4.3{\frac{L}{m^2\;h}}$ and acetic acid rejection was about 43% at these conditions.

  • This paper identifies trends in research methodology due to globalization. Context in both research and in practice and forms the key perspective for modern methodology and theory. Ecological perspectives are a necessary condition for quality global research. Human ecology researchers must advance the role of interdisciplinary and inter-functional perspectives and be open to collaborative relationships. These researchers must work in teams across disciplinary and functional boundaries. The paper discusses directions for research within the context of trends at U.S. federal agencies with applications to globalization and family life. Trends include: (a) use of diverse but rigorous methodologies; (b) recognition of the research-practice-research feedback loop;(c) primacy of context and diverse sampling; and (d) connections of research to problem solving. The terms promoted recently such as ″relationships″, ″diversity″ or ″problem-based″ are ingrained in human ecology. Key aspects for research in the next decade will be: (a) seeking diversity in sampling; (b) seeking colleagues with different perspectives; (c) incorporating meta-analysis into our work; (d) seeking meaningful results; (e) utilizing varieties of research methodologies to address our problems; and (0 understanding that practice must continually change as a function of research.

  • The introduction of zirconia-based materials to the dental field broadened the design and application limits of, all-ceramic restorations. Most ceramic restorations are adhesively luted to the prepared tooth, however, resin bonding to zirconia components is less reliable than those to other dental ceramic systems. It is important for high retention, prevention of microleakage, and increased fracture resistance, that bonding techniques be improved for zirconia systems. Strong resin bonding relies on micromechanical interlocking and adhesive chemical bonding to the ceramic surface, requiring surface roughening for mechanical bonding and surface activation for chemical adhesion. In many cases, high strength ceramic restorations do not require adhesive bonding to tooth structure and can be placed using conventional cements which rely only on micromechanical retention. However, resin bonding is desirable in some clinical situations. In addition, it is likely that strong chemical adhesion would lead to enhanced long-term fracture and fatigue resistance in the oral environment.

  • This study identifies communication patterns of groups using synchronous text communication medium for their group decision-making, and examines how these patterns are associated with creative solutions to problems. Our research suggests that certain communication behavior of groups, when appropriately organized, can be of help in enhancing creative production of outcomes. A qualitative study was conducted on communication patterns based on an analysis of text-based electronic conversation protocols. Specifically this research tried to overcome existing studies on electronic groups by focusing on interactive process of communication among participants. The major study conclusion; are: (1) The production of creative outcome may depend on the process or sequence of discussion among group members with synchronous text communication medium. That is, proper interactive responses and appropriate control of the discussion process are essential to obtain a high level of performance. (2) It is importantto make discuss rules based on meta-cognitive and interactive protocols in the early stage. Explicit rules relating to internal group processes as well as communication medium use are even more important to groups with electronic communication medium than face-to-face groups.
