The purpose of this study was to analyze research trends on subjective well-being in the elderly. To this end, 49 academic papers (general characteristics, research subjects, number of researchers, research variables, and research methods) retrieved through RISS were classified according to criteria. One or two research papers have been steadily published starting with two in 1988, but a slight increase in 2009 and 2010, four each, and five in 2014, respectively. By sample size, 201 to 300 were the most frequent with 14 studies. Quantitative studies were the most common as a research method, but 2 qualitative studies and 2 longitudinal studies were identified through trend analysis. It was confirmed that there are many variables related to physical health such as leisure sports, physical activity, sports for all, dance sports, and mobility discomfort as research topics. The number of studies on the elderly should be increased, and the need for qualitative research to explore the life experiences and meanings of old age is suggested.

Purpose: This study was conducted to investigate the safety of dental imaging in pregnant women with respect to fetal health. Materials and Methods: Searches were conducted of the PubMed, Scopus, and Web of Science databases in May 2023. The inclusion criteria encompassed cross-sectional and longitudinal studies that focused on the analysis of diagnostic dental imaging in pregnant women, as well as studies utilizing phantoms to simulate imaging examinations. The exclusion criteria consisted of reviews, letters to the editor, book chapters, and abstracts from scientific conferences and seminars. Results: A total of 3,913 articles were identified. Based on a review of the titles and abstracts, 3,892 articles were excluded, leaving 21 articles remaining for full-text review. Of these, 18 were excluded, and 4 additional articles were included as cross-references. Ultimately, 7 articles underwent quantitative-qualitative analysis. Three retrospective studies were focused on pregnant women who underwent dental imaging procedures. The remaining 4 studies utilized female phantoms to simulate imaging examinations and represent the radiation doses absorbed by the uterus or thyroid. Conclusion: Few dental radiology studies have been conducted to determine the safe radiation threshold for pregnant women. Additionally, the reviewed articles did not provide numbers of dental examinations, by type, corresponding to this dose. Dental imaging examinations of pregnant women should not be restricted if clinically indicated. Ultimately, practitioners must be able to justify the examination and should adhere to the "as low as diagnostically acceptable, being indication-oriented and patient-specific" (ALADAIP) principle of radioprotection.

Evidence on the relation of socioeconomic position (SEP) with health and illness is mounting in South Korea. Several unlinked studies and individually linked studies (longitudinal study) showed a graded inverse relationship between SEP and mortality among South Korean males and females. Based on the mortality relative ratios by occupational class reported in the published papers of South Korea and western countries, the magnitude of the socioeconomic inequality in mortality in South Korea seems to be similar to or even greater than that in western industrialized countries. A potential contribution of health related selection, health behaviors and psychosocial factors to explain this socioeconomic inequality in mortality was discussed. It was suggested that early life exposure measures would demonstrate a greater ability to explain socioeconomic inequalities in all-cause mortality than the above pathway variables in South Korea. This is based on the cause-specific structure of mortality among the South Korean population who have a relatively greater proportion of stomach cancer, hemorrhagic stroke, liver cancer and liver disease, and tuberculosis, which share early life exposures as important elements of their etiology, than western countries. However, the relative contribution of early and later life socioeconomic conditions in producing socioeconomic inequality in health may differ according to the outcome, thus remains to be investigated.

This study was designed to investigate the content of health behavior and to examine factors determining health behavior of nursing students(n=159) in relation to sociodemographic and cognitive variables. Cognitive variables were categorized into saliency of health, susceptibility to illness, and health locus of control. Data analysis prodecure included factor analysis and stepwise multivariate regressions using health behavior as dependent variables. Analysis showed; 1. As a whole, nursing students showed a tendency of lack in positive health behavior, especially in diet-related health behavior. 2. Multiple regression analysis revealed that the factors such as grade, saliency of health, and birth place were to be independently and significantly associated with health behavior: Upper grade students, high level of saliency, urban-born students tend to take health behavior positively. 3. The most influential factor among them was grade, but cognitive inspite of stereotype, poorly impact on health behavior with the exception health. We can guess the effect of education indirectively from these findindgs, but longitudinal studies need to consider the direct effect of education. The results also indicate that the respondents should be encouraged to take health behavior positively. The studies including more other cognitive variables would be conducted for the nursing students in relation to health behavior.

Purpose: The principal objective of this study was to assess the topics and research methods of smoking-related research and to suggest future research directions. Methods: The subjects of this study were smoking research articles supported by the National Health Promotion Funds from 1998 to 2007. A total of 41 articles were selected and analyzed from 1999 to 2005 using the frameworks such as topics, subjects contents, subjects, research field, and research design. Results: The most frequent topic of smoking-related research was the development & evaluation of educational programs for smoking prevention and smoking cessation (34.1%). The majority of the research subjects were adults (42.2%) and adolescents (35.9%). 31.7% of the total research researches was conducted at the nationwide population level. The most popular research design was the descriptive study (36.6%) in the non-experimental studies and nonequivalent control group pretest-posttest design(19.5%) in the experimental study studies. Conclusion: The topics of smoking research should be planned under governmental strategies for decreasing to a 30% reduction in of smoking rates, as established in the 2010 Health Plan. With regard to the methodological aspects, longitudinal and nationwide research was first required so that we could plan an evidence-based program for smoking prevention and smoking cessation.

Background: The expression of the proto-oncogene c-fos in spinal cord neurons following various noxious stimuli has been demonstrated in numerous studies. However, the pattern of expression of c-fos after incisional stimulus has not been evaluated. This study was designed to examine c-fos expression in an incisional pain model of rats. Methods: A 1 cm longitudinal incision was made through the skin, fascia and muscle of the plantar aspect of the hindpaw in enflurane-anesthetized rats. Withdrawal responses were measured using von Frey filaments at areas around the wound before surgery and for the next 48 hours. The expression of c-fos protein in the lumbar spinal cord was examined by immunohistochemistry. Results: After incision, c-fos was strongly expressed within laminae I, II, III, IV, V and VI ipsilateral to the incision. C-fos positive neurons were detected in the controlateral site, as well. Conclusions: These studies suggest that spinal c-fos protein may not be used as a specific marker for spinal nociceptive processing in an incisional pain model.

The Weddell Sea Anomaly (WSA) in the ionosphere is characterized by higher plasma density at night than during the day in the region near the Weddell Sea. According to previous studies on the WSA, it is known to occur mostly in southern summer and has not been reported in other seasons. We have utilized more than 13-year TOPEX TEC measurements in order to study how the WSA varies with seasons and how it changes with solar activity. The TOPEX TEC data have been extensively utilized for the climatological study of the ionosphere due to its excellent spatial and temporal coverage. We investigate the seasonal and solar activity variations of the WSA using four seasonal cases (Mar. equinox, Jun. solstice, Sep, equinox, and Dec. solstice) and two solar activity conditions (F10.7<120 for solar minimum and F10.7>120 for solar maximum conditions) for geomagnetically quiet periods. Our analysis shows that the WSA occurs only in the southern summer hemisphere for low F10.7, as in previous studies, but the WSA occurs all of seasons except for winter when F10.7 is high: it is most prominent during the December solstice (southern summer) and still strong during both equinoxes. The WSA appears to be an extreme case of global longitudinal variations at mid- and high-latitudes.

The purpose of this research is to find a better win-win growth strategy of Large and mid-sized IT service enterprises. Efficient win-win growth for large and mid-sized enterprises is essential for acquiring a solid global competitiveness in IT service industry. However, previous studies lack generalized and detailed findings, and therefore past strategies were based on fragmented analysis. To develop an efficient win-win growth for Large and mid-sized enterprises, global benchmarking and an in-depth analysis on deep-rooted problems in IT service industry has been conducted. Past and present policies on IT service industry have been reviewed based on desirable co-growth structure. Based on research, current policies are unable to support co-growth, and collaborative efforts between Large and mid-sized enterprises as well as square deals are necessary for win-win growth. A new policy paradigm has been derived and a roadmap for efficient co-growth strategy has been suggested. The results of this research can be used for building a better IT service industry polices. In future studies, a longitudinal analysis on the proposed co-growth strategy can be conducted.

This study investigated how variables of internalizing and externalizing problematic behaviors change according to gender and as time passes by and how the variables influence adolescent problematic behaviors. The variables selected for the analysis are personal variables, parent variables, peer and school variables, and community variables. longitudinal data collected for 4 years from the Korea Youth Panel Survey(KYPS) were utilized for the analysis. Data were collected initially from 2,707 fifth grade elementary students in 2005 and they were traced until 2008. The final respondents were 2,448 students. The findings are as follows. Frist, the statistical significance was found in changes of problematic behavioral variables in terms of the gender difference. Second, variables, such as self-esteem and self-control are negatively correlated to the problematic behaviors and stress level is strongly positively correlated to the behaviors. Third, the study pressure and peer attachment level are correlated to the initial value of internalizing problematic behaviors. In conclusion, given that more statistical significances were found at initial values than the change rates among variables, early intervention is important in addressing adolescent problematic behaviors.

Purpose: The purpose of this study was to identify the trends of occupational health nursing research by analyzing the Korean Journal of Occupational Health Nursing for the last 20 years. Methods: A total of 268 published papers during the 20 year period were analyzed with structured analysis forms. Results: Most of the articles were descriptive, but the number of experimental studies increased. Fifty-five percents of the subjects were healthy workers. Most common selection of subjects appeared to be based on convenience. Sixty-eight percent of research instruments were questionnaires and the reliability and the validity of instruments were described in approximately half of the studies. Parametric statistics were the main methods of data analysis, but some advanced statistics were often used rather than simple descriptive statistics. Mainly "health" has been studied (47.9%) among four meta-paradigms of nursing science. Conclusion: It is necessary to develop more rigorous and various research methodology such as longitudinal design, experimental study, or randomized controlled trial. Also, special attention must be paid to studying the environment of workers.
