PURPOSE
The aims of this study were to examine the trend of quantitative study in Korean Journal of Adult Nursing published between 1989-2011 and to provide future directions for nursing research in adult health nursing.
METHODS
A total of 883 published articles were reviewed, and main subject and the methodology were analyzed using descriptive statistics.
RESULTS
The most frequently cited keywords were elderly, quality of life, depression, knowledge, stress and anxiety. The survey study was the most popular research design (67.6%) followed by experimental (26.5%), and methodological study (5.5%) design. Over 80% of studies with translated or developed instruments reported reliability for psychometric analysis, while only 18% of the studies reported validity of the instruments they used. In the periods of 2006~2011, significantly more studies utilized experimental design, obtained IRB approval and written consent, and included power analysis for sample size calculation. In recent experimental study, educational program and complimentary therapy were the two most frequently used interventions.
CONCLUSION
Through the analysis of nursing studies published in Korean Journal of Adult Nursing, we found the number of experimental studies has increased and methodological rigor has improved in recent years.

PURPOSE
This study was a randomized single-blind trial of whole versus split-dose PEG solutions for colonoscopy preparation to compare the patient compliance, quality of bowel cleansing, and endoscopist's satisfaction.
METHODS
The participants were recruited from outpatients who planned to receive colonoscopy of C hospital in Busan. Sixty participants were randomly assigned to receive either a spit-dose group(n=30) consuming 2 liter of PEG solution twice, or a whole-dose group(n=30), consuming 4 liter of PEG solution once. These participants completed the questionnaire to assess their compliance before colonoscopy. The quality of bowel cleansing was assessed using the Ottawa Scale with the endoscopist who was blinded to the type of preparation, and their satisfaction by using VAS.
RESULTS
The participants who did not completely consume 4 liter of PEG solution were less in split-dose than in whole-dose group (0% vs 13.3%). The split-dose group complained less about abdominal pain(t=2.644, p=0.009) and abdominal bloating(t=2.802, p=0.013) with a statistical significance. For the quality of bowel preparation, there were no significant differences in the bowel cleansing scores and the endoscopist's satisfaction between two groups.
CONCLUSION
Colonic preparation with split-dose of PEG solution could be a more useful method for better patient compliance, with no significant impact on bowel cleansing quality.

PURPOSE
To evaluate physical characteristics, lifestyle related to bone-health, and bone mineral density (BMD) in mothers and their daughters and to determine the predictors of BMD. METHOD: BMDs at the forearm, lumbar spine, and femur were measured in 101 healthy, mother-daughter pairs by dual energy X-ray absorptiometry. Mother-daughter differences between general characteristics, means for BMDs were assessed by chi2-test, t-tests. Multiple regression analyses were used to identify predictors of BMD in each group. RESULTS: Mothers had significantly higher BMD than their daughters at forearm, lumbar spine, and femur. The predictors of mothers' BMDs were body weight, body mass index (BMI) and percentage body fat, explaining 5.1~31.6% of the variation in BMDs. BMI, percentage body fat and their mother's BMD of the corresponding site bone were predictors in daughters, explaining 17.5~31.6% of the variations in BMDs. CONCLUSION: These results indicate the importance of weight on bone that the BMDs seems to be related to fat free mass both in young-adult daughters and in middle aged mothers. These also suggest the importance of intervention for the development of BMD in daughter of mother with low BMD.

PURPOSE
This study were to investigate BMD of middle-aged women and to examine the relationships between BMD and Physical, Obstetric characteristics METHOD: The data was collected from 119 healthy women who were 40-60 years old. they were examined for BMD at 4 regions(forearm, lumbar, femur, whole body), %fat by DEXA and investigated physical, obstetric characteristics using scale, questionnaire from January to March, 2001.
RESULT
1) According to bone diagnostic results by WHO classification, 95.8% of forearm and whole body BMD were normal but 21.8-48.7% of lumbar and femur BMD(neck, trochanter, ward's triangle) were diagnosed osteoporosis or osteopnea. 2) The bones were significantly positive correlations of each other (r=.19-.69, p=.04-.00) and there were significant correlations between BMD and physical, obstetric characteristics such as age (r=-.22, p=.02), weight(r=.36~.48, p=.00), height(r=.22, p=.02), %fat(r=.19, p=.04) and age of first delivery(r=-.28, p=.00).
CONCLUSION
Based on this study, healthy middle-aged women were also exposed to risk of osteoporosis related to aging, change of physical conditions or hormonal release. Further research to develop nursing interventions for the purpose of preventing osteoporosis by modifying risk factors is suggested.

The Purpose of this study was to explore and describe the lived experience of the poor solitary elder by eliciting verbal descriptions of their experiences. The phenomenological approach in qualitative studies is used to serve this purpose. Colaizzi's method is used for phenomenological analysis of the data in this study. which were collected from 10 poor solitary elders. They were asked open ended and descriptive questions in order to get them to talk about their experiences in their own terms. Interviews were tape recorded and transcribed verbatim. From the protocols, 182 significant statements about lived experience were organized and then grouped into 4 theme clusters. The major themes that emerged from the analysis were 'Awareness of Power Declining'. 'Emotional Disturbances of The Self'. 'Love and Hatred to Family', 'Trying to Accept Life'. The result of this study showed that the poor solitary elder needed nursing care based on a deep understanding of their lived experiences in their everyday life. From this study of essential themes for understanding the poor solitary elder, Nurses and health workers must develop supportive programs for helping the poor solitary elder.

The purpose of this study was to provide basic informations for developing family-focused nursing interventions for families with chronic illness. the results of this study were as follows. In family caregiver systems, spouses of chronically ill patients showed higher anxiety scores9t=4.71, P=.000) and higher scores of the perceived importance of family functioning(t=3.67, P=.000) than those of children of chronically ill patients. But spouses showed lower scores of the satisfaction of family functioning (t=2.92, P=.005) than those of children of chronically ill patients. For spouses of chronically ill patients, the correlation between the satisfaction of family functioning and anxiety turned out to be significant9r=-.518, P=.001). However for children the correlation between them was not statistically significant. Findings of this study suggest that families with chronic illness need family-focused nursing interventions to relieve their anxiety and to improve family functioning. In conclusion, the investigation about family functioning and anxiety provides useful information for family-focused nursing care, especially for spouses of chronically ill patients. This information will contribute to developing the support systems for family caregivers and the education programs that helps chronically ill patients.
