PURPOSE: This study was conducted to evaluate the effectiveness of autogenic training on stress responses through a systematic review and meta-analysis. METHODS: A systematic search was conducted using eight core electronic databases (Embase, CENTRAL, Medline, CINAHL, PsycInfo, DBpia, KISS, and RISS). To estimate the effect size, a meta-analysis of the studies was performed using RevMan 5.3.5 program. RESULTS: A total 21 studies out of 950 studies were included in the review, and 11 were included for meta-analysis. These studies showed that autogenic training decreased anxiety and depression, and increased the high frequency of heart rate variability. Calculations to understand the effect of autogenic training on anxiety, through a meta-analysis, observed a reduction effect of anxiety score by 1.37 points (n=85, SMD=−1.37: 95% CI −2.07 to −0.67), in the studies on short-term intervention targeting healthy adults. On the other hand, similar calculations to understand the effect of autogenic training on depression observed, a reduction effect on the depression score by 0.29 point (n=327, SMD=−0.29: 95% CI −0.50 to −0.07), in the studies on long term intervention targeting the patient group. CONCLUSION: Autogenic training is effective for adults' stress management, and nurses will be able to effectively perform autogenic training programs for workers' stress relief at the workplace.

PURPOSE: The purpose of this study was to identify body esteem, body figure discrepancy and depression in women college students. METHOD: The data were collected during April and May, 2004 using a questionnaire. The participants were 364 women college students attending universities in Seoul and Gangwon-Do. RESULTS: The BMI for under weight, normal weight and overweight for the college women were 49.2%, 48.3%, 2.5% respectively. But 52.6% of the students perceived themselves as obese and only 11.5% described themselves as being 'thin'. The mean scores for BMI, body esteem, body figure discrepancy and depression were 20.11+/-2.20, 2.36+/-.79, 1.07+/-.58 and 1.20+/-.48 respectively. Significant difference was found in body esteem score (F=26.389, p<.0001) and body figure discrepancy (F=64.167, p<.0001) according to BMI scores. There were negative correlations between body esteem and body figure discrepancy (r=-.582, p=.0001), between body esteem and depression (r=-.120, p=.028), between body esteem and BMI (r=-.422, p=.0001), and a positive correlation between body figure discrepancy and BMI (r=.630, p=.0001). Factors such as body figure discrepancy, BMI and depression explained 36.7% of the variance in students' body esteem. CONCLUSION: This study suggests that an intervention program is necessary for women college students to increase their body-esteem.

PURPOSE: To calculate the appearance of the image distortion from metallic artifacts and to determine the location of a metallic needle from a distorted MR image. MATERIALS AND METHODS: To examine metal artifacts, an infinite metal cylinder in a strong magnetic field are assumed. The cylinder's axis leaned toward the magnetic field along some arbitrary angle. The Laplace equation for this situation was solved to investigate the magnetic field distortion, and the simulation was performed to evaluation the image artifact caused by both readout and slice-selection gradient field. Using the result of the calculation, the exact locations of the metal cylinder were calculated from acquired images. RESULTS: The distances between the center and the folded point are measured from images and calculated. Percentage errors between the measured and calculated distance were less than 5%, except for one case. CONCLUSION: The simulation was successfully performed when the metal cylinder was skewed at an arbitrary tilted angle relative to the main magnetic field. This method will make it possible to monitor and guide both biopsy and surgery with real time MRI.

BACKGROUND: This is a theory verification study in which the theory of planned behavior (TPB) of Ajzen is applied to predict operating room (OR) infection control behavior. The study was carried out to know the path of attitude, subjective norm, perceived behavioral control, and intention towards OR infection control behavior. METHODS: A total of 178 OR nurses working at 13 hospitals in Seoul were the subjects of this study. A questionnaire survey was performed; the data were collected from April 6 to April 19, 2005 and analyzed with t-test, ANOVA, multiple regression, and person's correlation using SPSS program. Using AMOS, the factors of TPB were analyzed with path analysis. RESULTS: The total mean of infection control behavior of OR nurses was 4.37 points out of possible 5.0, and asepsis/operating instrument sterilization had 4.69, which was the highest among all areas of infection control behavior. In case of the relation between attitude, subjective norm, perceived behavior control, and intention, there was the strongest relation of cause and effect (path coefficient 0.38, 39%). In case of intention, perceived behavior control, and behavior, the relation of cause and effect between intention and behavior was path coefficient 0.17 and behavior was path coefficient 0.19. The degree of explanation was 10%. CONCLUSION: We should try to improve environment management in behavior area, and through this study, the importance of education was verified.

BACKGROUND: Following the improvement of the economic status and increasing medical availability, the interest for the public health and nutrition in elderly is increasing in Korea. It is well known that aging is associated with the deterioration of nutritional status, but in Korea, there were no clear data about that yet. PURPOSE: This study was performed to identify the normal distribution of the nutritional indices such as biochemical and anthropometric variables, showing the association between nutritional risk factor and aging. METHODS: Among 151,000 subjects over 40 year olds in Jung-Up County, Korea, 1051 were selected for a random cluster sample. After the blood tests and anthropometric measurements were performed during Dec 1996 to Feb 1997. RESULTS: Of the 1051 subjects(M:F=410:641), 340 were over 65 years(elderly) at the enroll time, while 711 were between 40 to 65 years(middle aged). Triceps skin fold thickness(TSF), body mass index(BMI), hematocrit(Hct) serum protein and albumin showed a weak negative correlation with age, whereas not in the case of the waisthip ratio(WHR), leucocytes, serum cholesterol and creatinine. Compared with middle aged with elderiy, TSF, BMI, albumin showed a significant differences(p<0.05). CONCLUSION: We showed the normal distribution of the variable nutritional indices and their changes associated with aging in the ambulatory elderly Korean living in the rural community. It needs further follow-up study including association with mortality.

PURPOSE: This study was done to examine good death awareness, attitudes toward advance directives (ADs), and preference for care near the end-of-life (PCEOL) of hospitalized elders in long-term care hospitals. Relevant characteristics were investigated as well as correlation of the variables. METHODS: This descriptive research study involved 161 hospitalized elderly patients in long-term care hospitals. A self-report questionnaire was used to measure Good Death Scale, ADs Survey, PCEOL Scale, and general characteristics. Collected data were analyzed using descriptive statistics, t-test, ANOVA, and Pearson correlation with SPSS/WIN 23.0. RESULTS: In terms of good death awareness, a significant difference was observed; in according to age (F=3.35, p=.037), payer of treatment costs (F=3.98, p=.021), mobility (F=3.97, p=.021), heard discussion about ADs (t=−3.89, p<.001), and willing to complete ADs (t=2.12, p=.036). As far as attitudes toward ADs, the participants presented significant difference depending on religion (t=2.38, p=.018), average monthly income (F=3.91, p=.022), duration of hospital admission (F=5.33, p=.006), person to discuss ADs (t=−2.76, p=.006). On PCEOL, there was a significant difference, depending on religion (t=−3.59, p<.001) and perceived health status (F=3.93, p=.022). Finally, as for how the variables were related to each other, good death awareness and attitudes toward ADs had a weak positive correlation with PCEOL. CONCLUSION: To help seniors staying in nursing homes face a good death and enjoy autonomy, there should be educational and support systems that reflect each individual's sociodemographic characteristics so that the seniors can choose what kind of care they want to receive near the end-of-life.

PURPOSE: this study was carried out to identify family environmental factors related to changes in sexual attitudes through a sexuality education based on correct sexual attitude for middle school students. METHODS: The subjects were 141 students (67 boys and 74 girls) in 4 classes of the first grade of a coeducational middle school, in Seoul. The school nurse provided the sexuality education for 18 hours over 16 weeks. RESULTS: After the sexuality education, there was a significant increase in sexual attitude(t=59.06, p<.001). For family environmental factors related to changes in sexual attitude, 'relationship with parents' was a significant factor for both boys and girls. For the girls, there were many other related factors such as 'parents' openness', 'family structure', and 'economic status'. Significant factors were 'Family structure' for attitude to abortion and 'parents' openness' for attitude to intercourse before marriage. CONCLUSIONS: Based on these results, systematic sexuality education is needed to enhance correct sexual attitudes in youth. To increase the effect of sexuality education, it should include contents to improve relationships with patents. Also, for parents, programs to improve relationships with their children and to change the values such as openness may also be required.

Considerable efforts have been made to prevent and manage hypertension and diabetes, but the prevalence of these diseases has not changed significantly over the past 10 years. Hypertension and diabetes are chronic conditions requiring continuous treatment and management. Controlling blood pressure and blood sugar levels can prevent life-threatening complications and a deterioration in the quality of life. Community-centered primary health care is characterized by inclusiveness and continuous contact. Well-established primary health care services can reduce the number of unnecessary emergency room visits, hospitalizations, and medical tests, and therefore minimize unnecessary medical expenses. However, the number of patients treated for mild chronic diseases at large hospitals has increased, with a concomitant decrease in the proportion of outpatient clinic visits (41.6% in 2007 vs. 37.8% in 2016). Thus, there is a clear need to strengthen primary health care, including for the treatment of chronic diseases. To establish a chronic diseases management system based on local clinics, the Ministry of Health and Welfare of Korea launched a pilot chronic diseases management program aimed at increasing patient acceptance of local primary health care. The program was implemented in 2014, 2016, and 2019. This review examines the short-term impact of the pilot program with respect to the prevention and management of hypertension and diabetes.
