Purpose: The purpose of this study was to analyze research trends and to suggest future directions for research on families of patients with chronic disease. Method: The method used was a review of 83 dissertations and articles related to these families published in Korea between 1980 and 2002. Analysis included design of the study, sources of data, interventions for experimental research and main concepts for non-experimental research. Result: It was found that 80.7% of the studies were non-experimental research and 85.1% of these were descriptive surveys. In 79.5% of research studies, data were collected at a hospital. Nursing interventions in the experimental studies included stress management, education, strengthening functional communication among family members and nursing management. The major concepts were family burden, family stress, and coping, and family experience. Conclusion: It is necessary that research on the family-as-a-client be more focused and that the results of family related research be applied to the family as a unit. Development of research instruments to measure the phenomena of Korean families of patients with chronic disease is also needed.

Objectives: The purpose of this study was to investigate the current state and trends of health-related research on foreign migrants living in Korea. Methods: Among 85 articles identified via PubMed and RISS and additional 7 articles by ancestry search, 28 were selected for the review. Two authors independently reviewed the articles using a literature review matrix and examined together the three aspects of the studies: research methods, research topics, and research results. Results: Most of the articles were published between 2005-2009, and only 3 studies used an interdisciplinary approach. Most were exploratory and there were 4 intervention studies: three of them examined the effect of an art therapy on acculturative stress and mental health among marriage migrant women. The lack of information on informed consent, approval of institutional review board, and the validity/reliability of the translated instruments were noted. Conclusions: Research is needed to examine migrants' health behaviors, the prevalence of chronic illness among migrants, and the influence of acculturation on the use of health resources, health behaviors, and health status. Researchers should be aware of ethnic issues when they work with foreign migrants.

This study sought to analyze the trends in research on Korean fathers with young children. In this study, journal articles related to child and family studies, early childhood education and childcare published between 1980 and 2006 were analyzed for research frequency, content, and methodology. The study results were as follows. First, 56 research articles on Korean fathers with young children were published during this period of time. Second, the research was primarily focused on fathering attitudes and the relationships between the characteristics of the father and the development of the child. Third, the majority of the studies used methods categorized as quantitative and non-experimental: the subjects included more than 100 fathers with 3-5-year-old children. Research instruments validated in foreign countries (52.4%), surveys (75.4%), and quantitative data analysis methods (98.2%) were primarily used in these research studies. Finally, the results of this study suggest that further studies concerning Korean fathers with young children need to be conducted according to current research trends, content, and methodology.

The analysis of nuclear materials and environmental samples is an important issue in nuclear safeguards and nuclear forensics. An analysis technique for safeguard samples has been developed for the detection of undeclared nuclear activities and verification of declared nuclear activities, while nuclear forensics has been developed to trace the origins and intended use of illicitly trafficked nuclear or radioactive materials. In these two analytical techniques, mass spectrometry has played an important role in determining the isotope ratio of various nuclides, contents of trace elements, and production dates. These two techniques typically use similar analytical instruments, but the analytical procedure and the interpretation of analytical results differ depending on the analytical purpose. The isotopic ratio of the samples is considered the most important result in an environmental sample analysis, while age dating and impurity analysis may also be important for nuclear forensics. In this review, important aspects of these techniques are compared and the role of mass spectrometry, along with recent progress in related technologies, are discussed.

Due to international law the Antarctic is currently the best protected large ecosystem on earth, providing the opportunity for scientific research into processes of both regional and global importance. However, it is impossible to carry out research activities without minor disturbances to the environment. The Weddell Sea with its shelf inhabiting fauna can be considered to be representative for the entire Antarctic shelf with exceptions. It has generally escaped major anthropogenic impact but it is the only area in the high latitude Antarctic where long-term research fishing has been carried out. There are two main results combining aspects of nature conservation and benthos research. Firstly, the use of dredges has clearly decreased over the last two decades, whilst the use of non-invasive underwater photography and video has significantly increased. Secondly, during the same period icebergs destroyed an area of the seafloor and its fauna more than 2000-times greater than the area affected by research trawls. The increased use of imaging methods, Remotely Operated Vehicles (ROV) and other modem instruments, as well as statistically based and coordinated sampling strategies can contribute to both a better understanding of ecosystem function and to an ongoing reduction in anthropogenic impact.

Yellow Sea Buoy (YSB) was moored in the center of the Yellow Sea at 35$^{\circ}$51'36"N, 124$^{\circ}$34'42"E, on 12 September 2007. YSB is a large buoy of 10 m diameter, and as such is more durable against collision by ships and less likely to be lost or removed by fishing nets compared to small ordinary buoys of 2.3 m diameter. YSB is equipped with 12 kinds of oceanic and meteorologic instruments, and transfers its realtime observation data to KORDI through ORBCOMM system every 1 hour. Data on ocean winds, air temperature, air pressure, and sea temperature appear to be accurate, while water property sensors (AAQ1183), which are sensitive to fouling, are producing errors. YSB (2007), Ieodo ocean research station (2003), and Gageocho ocean research station, which was completed in October 2009, will establish the 2 degrees interval by latitude in the Yellow Sea, and they will contribute though the 'Operational Oceanography System' as the important realtime observation network.

In this study, we investigated the effect of factors that influence the measurement of smoke density using synthetic rubber flooring. The characteristics of rolling stock in an enclosed environment can cause enormous loss of life by smoke inhalation during fires inside passenger cars. The amount of smoke generation from interior materials for rolling stock is strictly restricted domestically and in other countries. Precise measurement of smoke density is therefore required to assess the fire performance of interior materials. Major factors that influence the measurement of smoke density include the uniformity of the specimen, the variations in conditions and instruments, and the operational and maintenance environment of the instruments. The contribution of factors was analyzed by estimating the uncertainty to investigate the contribution ratios of the major factors. The results show a contribution ratio of about 86% for the variation from the measurement of light transmission using a photomultiplier tube. Thus, this factor was the most representative for the measurement of smoke density. The contribution ratio of the other factors was low at about 11%, including irradiant flux conditions (${\pm}0.5 kW/m^2$) and the influence of the operational and maintenance environment of the instrument. These results were obtained using specimens with high uniformity.

Purpose: To develop strategies for research and development (R&D) in nursing service based on the policy direction of government supported R&D in Korea. Methods: This was a descriptive study to develop strategies for promoting R&D in nursing by analyzing investment trends and status quo, policy directions, and implementation of the details of government supported R&D through government reports, websites of relevant agencies and literature reviews. Results: Few nursing experts participated in clinical research on overcoming major diseases and in R&D for well-being and care. Development of nursing topics that meet the direction of government supported R&D were lacking. Insufficient implementation of nursing service R&D in a timely manner equipped with a performance-based system. Few research studies in R&D projects that included research using big data or contributing to developing medical instruments. Finally, an insufficient number of nursing specialists participated on government R&D advisory committees. Conclusion: For nursing service R&D development efforts should be toward quantitative expansion and qualitative improvements by sensitively recognizing policy direction of government supported R&D. The promotional capacity of nursing service R&D must be reinforced through a multidisciplinary approach and collaborative association with other professionals and the inclusion of nurse specialists on government R&D advisory committees.

This paper focuses on the applicability of a continuous monitoring method on trace sulfur compounds in the ambient air by TD and GC/PFPD. The target compounds for monitoring include H2S(hydrogen sulfide), Methyl mercaptan, Dimethyl Sulfide, and Dimethyl disulfide. The result of QA/QC on monitoring instruments satisfies all the standards of Odor Measurement and Analysis Method, showing that the reproductivity of the compounds by concentration is within 10%, linearity is above 0.98 of a correlation efficient, method detection limit is 0.16 ppb by MM standard, and recovery rate is over 70%. Monitoring was conducted for two years from March 2006 to February 2008. As a result of the monitoring, the average concentration of H2S was 0.08 ppb, with the maximum concentration at 16.15 ppb. The result indicates that it is reasonable to do continuous monitoring as there appears a spontaneous event of high concentration by the condition of the site during monitoring odor-causing substances. Therefore, it is suggested that the continuous monitoring method used in this paper is appropriate to identify the characteristics of sudden occurrence and concentration variations of sulfur compounds.
