A meta-analysis is a statistical integration method that delivers an opportunity to overview the entire result of integrating and analyzing many quantitative research results. This study will find meaningful mediator variables for criterion variables that affect between pre and post in metabolic syndrome studies, on the basis of the results of a meta-analysis. We reviewed a total of 36 studies related metabolic syndrome published in Korean journals between 2000 and 2015, where a cause and effect relationship is established between variables that are specified in the conceptual model of this study. In this meta-analysis, the path between pre and post in waist circumference showed the biggest effect size (r = .420). The second biggest effect size (r = -.402) was found the path between pre and post in high density lipoprotein cholesterol. By the way, one the smallest effect size (r = .234) was obtained the path between pre and post in diastolic blood pressure. Thus, we present the theoretical and practical implications of these results and discuss the differences between these results through a comparative analysis with previous studies.

The purpose of this study were to evaluate the effect on the reversion of sedation induced by midazolam with flumazenil and to determine the plasma concentration of flumazenil according to the method of administration. Intranasal and intravenous flumazenil were administered to sedated health volunteers aged from 23 to 25 years, in doses typical of those used clinically to induce sedation with midazolam and for reversal with flumazenil. Objective assessment for degree of sedation and vital signs, plasma concentration were made for 2 hours period. 1. Systolic and diastolic blood pressure, $SpO_2$ were not changed by adminstration of flumazenil in sedated subject with midazolam, but pulse rate was increased temporarily. 2. Flumazenil showed the reversal of the sedative effect induced by midazolam regardless of administration methods. But intravenous administration showed more effect on the degree and the duration of reversion than intranasal administration with the exception of on set time. 3. Peak plasma concentration of flumazenil administered by intranasal route reached after 2 min and that of flumazenil administered by intravenous route was 4 min. Thus uptake of flumazenil did not showed any difference in accordance with the adminstration route. 4. Administration of flumazenil resulted in the temporary increase of midazolam plasma concentration.

Background: In patients with obstructive sleep apnea syndrome(OSAS), there are several factors increasing upper airway resistance and there is a predisposition to compromised respiratory function during waking and sleep related to constitutional factors including a tendency to obesity. Several recent studies have suggested a possible relationship between sleep apnea(SA) and systemic hypertension. But the possible pathophysiologic link between SA and hypertension is still unclear. In this study, we have examined the relationship among age, body mass index(BMI), pulmonary function parameters and polysomnographic data in patients with OSAS. And also we tried to know the difference among these parameters between hypertensive OSAS and normotensive OSAS patients. Methods: Patients underwent a full night of polysomnography and measured pulmonary function during waking. OSAS was diagnosed if patients had more than 5 apneas per hour(apnea index, AI). A careful history of previously known or present hypertension was obtained from each patient, and patients with systolic blood pressure $\geq$ 160mmHg and/or diastolic blood pressure $\geq$ 95mmHg were classified as hypertensives. Results: The noctural nadir of arterial oxygen saturation($SaO_2$ nadir) was negatively related to AI and respiratory disturbance index(RDI), and the degree of noctural oxygen desaturation(DOD) was positively related to AI and RDI. BMI contributed to AI, RDI, $SaO_2$ nadir and DOD values. And also BMI contributed to $FEV_1,\;FEV_1/FVC$ and DLco values. There was a correlation between airway resistance(Raw) and AI, and there was a inverse correlation between DLco and DOD. But there was no difference among these parameters between hypertensive OSAS and normotensive OSAS patients. Conclusion: The obesity contributed to the compromised respiratory function and the severity of OSAS. AI and RDI were important factors in the severity of hypoxia during sleep. The measurement of pulmonary function parameters including Raw and DLco may be helpful in the prediction and assessment of OSAS patients. But we could not find clear difference between hypertensive and normotensive OSAS patients.

Purpose: The purpose of this study was to analyze the effects of aromatherapy on stress using meta-analysis. Methods: Meta-analysis was done with 21 published studies, and data were analyzed with the SAS 9.1 program. Results: Fifty eight effect size was estimated with data from 21 published studies. Overall mean effect size (ES), and mean effect size of dependence variables according to the type of intervention and subject and according to the total amount of time spent in aromatherapy were estimated. Overall mean effect size of the effects of aromatherapy was .593, and the subjective stress (.983) was most effective in the physiological faculty, followed by mean effect size of cortisol (.648) and pulse (.40). On the other hand, mean effect size of systolic blood pressure (.490) was moderate, and that of diastolic blood pressure (.401) was not large. Mean effect size of elderly (.706) cancer patients was considerable(.337). There were significant differences depending on the subjects. With regards to the types of aromatherapy, the effect size of aroma massage combined with inhalation therapy was .590, and there were no significant differences between the intervention methods. With regards to the time of intervention, $20{\sim}30$ minutes spent in aromatherapy was .730, and there were no significant differences between the times of intervention. The relationship between the effect size and intervention frequency was r=.349 and showed significant difference. Conclusion: This result suggests that aromatherapy is an effective intervention to reduce stress for subjects. Nursing intervention protocol by using aromatherapy should be developed and applied in clinical and community settings. Further studies on the effects of aromatherapy on stress should be done by using meta-analysis.

The purpose of this study was to evaluate the health condition and nutritional status in female university students in Masan. The 285 subjects aged 20.1 years (18~26 years) were assessed with a set of questionnaire composed of general information, food, smoking, drinking and exercise habits, anthropometric measurements, blood pressure measurements, 24-hour recall and food frequency questionnaire. The rates of smoking and alcohol drinking habits were 1.8% and 82.5%, respectively. All the subjects had the experience of passive smoking. The 11% of the students exercised regularly and 11.6% ate meal regularly. The average height and weight of subjects were 161.0 ㎝ and 53.9 ㎏, respectively and the BMI was calculated as 20.8${\pm}$2.6 ㎏/$m^2$:The 13.3% of subjects were underweight, while 6.7% of them were overweight. The mean value for body fat was 26.4% and subscapular and tricep skinfolds thickness were 14.2 ㎜ and 16.9 ㎜, and waist-hip ratio was 0.72. The systolic/diastolic blood pressure of the subjects was 115.9 ㎜Hg/70.9 ㎜Hg. Except protein, phosphorous, vitamin E, B_6 and C, the average intakes of energy and nutrients were below the Korea recom-mended dietary allowance (RDA). Especially, intakes of calcium, iron and zinc were the lowest, as <70% of RDA. The proportion of energy derived from carbohydrates : protein : fat was 58.0 : 15.8 : 26.2. The 10 frequently consumed food were ssalbap (47.2/mon), kimchi (35.6/mon), onion (16.8/mon), japgokbap (15.1/mon), sesame oil (14.1/mon), carbonated drink (13.3/mon), grapes (12.7/mon), ice cream (12.4/mon), milk (11.9/mon) and water-melon (10.6/mon). Results of this study could be useful for planning nutrition education programs for female university students in this area to improve their dietary habit and health status.

Skipping breakfast is a risk factor closely related to metabolic syndrome and obesity. We analyzed the relationship between breakfast size, metabolic syndrome and obesity. The study included 5,548 adults who visited a health promotion center at Pusan National University from January to November of 2006. Subjects were divided into four groups according to breakfast size - skipper group (no breakfast), small intake group, medium intake group and large intake group. 959 (17.3%) of the 5548 subjects were included in the Skipper group. Intake of daily calories, proteins, carbohydrates and fats was the lowest in the Skipper group. Breakfast size increased linearly with an increased intake of daily calories, proteins, carbohydrates and fats. Body mass index ($23.4\;kg/m^2$) and waist circumference (79.6 cm) were the lowest in the Small intake group. In the Small intake group, triglycerides, fasting plasma glucose, systolic blood pressure and diastolic blood pressure were the lowest, and high density lipoprotein cholesterol levels were the highest. The number of metabolic risk factors was the lowest in Small intake group. Odds ratio of metabolic syndrome (Odds ratio=0.612) was the lowest in Small intake group. Along with increasing breakfast size, the odds ratio also increased. In this study, breakfast size was found to influence metabolic risk factors. Skipping breakfast worsened metabolic risk factors, while a small breakfast size had a favorable effect on metabolic risk factors.

This study examined the relation between anger-coping types and hypertension in employed men aged $40\sim60$ who consented to participate during the biannual physical checkup in the department of health management in 1988. The subjects analyzed were five hundred thirteen excluding those having hypertension history and/or current antihypertensive medications. Anger-coping types were constructed from the Harburg's model with two hypothetical anger-provoking situations involving wife and boss. Hypertensives were defined more than 140mmHg systolic blood pressure and/or 90mmHg diastolic blood pressure. Hypertensives were one hundred fifty two(29.6%) and those who suppressed their anger were 61.6% and 62.8% in wife and boss situations respectively. Items of anger, guilt, protest, and suppressed anger in wife situation showed odds ratios of 0.78-0.94 without statistical significance. But four items in boss situation showed odds ratios more than 1, especially anger-in types of anger item had 1.58 times the prevalence of hypertension of anger-out types(95% confidence intervals(CI) $1.06\sim2.35$) and subjects who indicated that suppressed their anger had 1.55 times the prevalence of hypertension of those who expressed their anger(95% CI $1.03\sim2.32$). For anger suppressed vs. expressed types of total suppressed anger index, prevalence of hypertension was 1.31 (95% CI $0.83\sim2.08$). After adjusting for age, body mass index, smoking and drinking, the odds ratios were slightly increased in both situations except guilt items compared with univariate analysis. These results suggest that the relation between Harburg's anger-coping model and hypertension is replicated partially in this subjects.

The objective of this study was to investigate the effects of nutrition education based on ubiquitous healthcare (u-health) service on changes in dietary habits, nutrition intake, and risk factors for metabolic syndrome in male workers. In total, 72 male office workers with at least three risk factors of the National Cholesterol Education Program-Adult Treatment Panel III were recruited as subjects. Anthropometric measurements and biochemical analyses were conducted on all subjects. Dietary habits and nutrient intake were determined by a questionnaire using the 24-hour dietary recall method before and after nutrition education. Subjects measured their body composition, blood pressure, and physical activity more than once per week during the 12 weeks using the u-health care equipment and sent these data to a central database system using a personal computer. Individual nutrition counseling was provided four times on the first, fourth, eight, and twelfth weeks. The results showed significant decreases in abdominal circumference, body fat (%), diastolic blood pressure, serum triglycerides, and serum total cholesterol during the 12 weeks. Subjects with more than 12 measurements showed significant reductions in abdominal circumference, body fat (%), serum triglyceride, and serum total cholesterol. Mean intake of dietary fiber, animal calcium, potassium, vitamin C, and folic acid after nutrition education were higher than those before nutrition education. Participants showed significant increases in the frequencies of consuming protein foods (meat, fish, eggs, beans, tofu, etc.) and vegetables. In conclusion, nutrition education through the u-health service resulted in positive effects on the risk factors for metabolic syndrome, nutrient intake, and dietary habits.
