Objectives: Photodynamic therapy has been proven to promote additional clinical and microbiological benefits in the treatment of chronic periodontitis and aggressive periodontitis. The purpose of this study is to assess the effectiveness of the photodynamic therapy for patient with periodontitis. Methods: We searched the eight Korean databases and Ovid-MEDLINE, Ovid-EMBASE, Cochrane Library. Total 300 studies were searched and 13 studies were included in the final assessment. Each of the stages from literature search and extraction of data were carried out independently by 2 researchers. We used tools of Scottish Intercollegiate Guidelines Networks for assessment of the quality of studies. Results: The safety of the photodynamic therapy was assessed by bleeding. The effectiveness of the photodynamic therapy was assessed by the reduction of Probing pocket depth (PPD) and the gain of Clinical attachment level (CAL). The mean difference of PPD was 0.46(95% CI 0.09~0.82), (p=.01).). The mean difference of CAL was ?0.49(95% CI ?1.12~0.14), (p=.13). Conclusion: The additional use of $^{\circ}{\infty}$Antimicrobial Photodynamic Therapy for Periodontitis$^{\circ}{\pm}$ caused hemorrhage to similar extents to conventional treatment modalities, where scaling and root planing are solely performed, in patients with periodontitis who are expected to have a lower degree of treatment response to non-surgical or surgical periodontal therapies (implant or refractory periodontitis) and those where there is a concern for the possible occurrence of antimicrobial side effects or resistance. This indicates that there are no problems with its safety. But there were no consistent reports about the effects of the additional use of photodynamic therapy. This led to a decision that the safety and efficacy of the current technology deserve further studies (Recommendation rating of A, Classification of technology II-a).

In this study, to investigate the effects of herb aroma components, the BDI test was performed with the 124 students of the Youngdong University and the subjects whose score was 16 or higher were selected and allocated to the herb-extracted aroma-treated group and the non-treated group, 27 and 10 students for each group. The BDI and SDS tests were carried out at each stage (before and after the treatment, 10 days later and 30 days later). The result showed that the pre-treatment BDI test result was significantly different from all those of the post-treatment test, and the tests after 10 days and 30 days in the aroma-treated group. In the SDS test, the pre-treatment test result was significantly different from the results of the post-treatment test and the test after 10 days, while it was not significantly different from the result of the test after 30 days. Additionally, to verify whether the change within the group is larger than that by natural recovery or not, ANCOVA was performed with respect to the difference in the pre-treatment test score between the groups depending on whether the treatment was given or not, having the SDS pre-treatment score as the covariate, and the result showed that the post-treatment test scores were significantly different. Thus, it was verified that, if the SDS test score is considered as the depression indicator, the effect of aromatherapy was greater than the change by natural recovery. The difference in the post-treatment test score was analyzed depending on whether the treatment was given or not, having the BDI pre-treatment test score as the control variable, and the result showed that the post-treatment test scores were not significantly different. Based on such a theoretical verification, it is assumed that the nature-friendly treatment method using herb aroma components can be a great help in suppressing depression. Therefore, it is expected that herb aroma components can provide systematic therapeutic effect on the suppression of depression.

Purpose: The purpose of this study was to evaluate the effectiveness of non-pharmacologic interventions for chronic nonspecific low back pain (CLBP) in adults aged 18-64 years. Methods: We searched for potentially relevant randomized controlled trials and non-randomized controlled trials through five Korean electronic databases (i.e., Korean Studies Information Service System, Research Information Sharing Service, Korean Medical Database, KoreaMed, and National Assembly Library) published from January 2010 to May 2019. Two investigators independently selected the studies based on the criteria and assessed risk of bias in the included studies. We estimated the effect size of interventions using Comprehensive Meta Analysis 3.3. Results: Of 10,151 studies, 26 studies met the inclusion criteria and 15 studies were included in the meta-analysis. Exercise reduced low back pain (Hedges's g=-1.53, 95% CI: -2.22 to -0.85) and pain-related disabilities (Hedges's g=-0.92, 95% CI: -1.40 to -0.45). We found that taping was effective in decreasing low back pain (Hedges's g=-1.12, 95% CI: -1.51 to -0.73) and pain-related disabilities (Hedges's g=-0.50, 95% CI: -0.93 to -0.07). Manual therapy yielded a marginally significant reduction in low back pain (Hedges's g=-2.32, 95% CI: -4.64 to 0.00), the therapy was not effective in decreasing pain-related disabilities. Conclusion: Although there was little evidence for the effectiveness of manual therapy in adults with CLBP, exercise and taping were effective to relieve pain and pain-related disabilities. Based on these findings, we suggest the development of non-pharmacologic interventions or a nursing intervention protocol for the CLBP management. Also, nurses should consider implementation of effective non-pharmacologic interventions for CLBP.

Objective: This study investigates the impact of multimorbidity on work through a literature review of longitudinal studies. Methods: A systematic review was carried out in the databases Lilacs, SciELO, PAHO, PubMed/Medline, Scopus, Web of Science, and Cochrane. There were no restrictions regarding the year of publication or language to maximize the identification of relevant literature. The quality of studies was assessed by the protocol STrengthening the Reporting of OBservational studies in Epidemiology (STROBE). Results: An initial database search identified 7522 registries, and at the end of the analysis, 7 manuscripts were included in the review. Several studies have demonstrated direct and indirect impacts of multimorbidity on the health of workers. For this, the number of missed days due to health-related issues was evaluated, as well as the reduction in work productivity of the unhealthy worker, vulnerability of the worker with multimorbidity regarding higher indices of dismissal and recruitment difficulties, and incidence of early retirement and/or receipt of benefits due to disabilities. Conclusions: Multimorbidity has a negative impact on work, with damages to quality of life and work productivity, worsening the absenteeism/presenteeism indices, enhancing the chances of temporary or permanent leaves, and lowering employability and admission of individuals with multimorbidity.

This study was designed to evaluate Saturday nutrition classes for obese elementary students in Chungnam Province. Obesity index, nutrient intake, nutrition knowledge, nutrition attitude, and self-satisfaction of 36 obese elementary students were compared before and after attending nutrition classes every other Saturday for 3 months. The average age, height, weight, body fat, % body fat, and obesity index were 11.9 years, 145.5 cm, 53.3 kg, 24.5 kg, 45.7%, and 32.4%, respectively. Most of the subjects(94.5%) viewed themselves as fat. Sixty-three percent of children were discontent with their body-image. All answered that they have experience with weight control. The major methods of weight control were exercise and reduction of snacks. The mean serum cholesterol, blood glucose, GOT/GPT, and hemoglobin were 177.4 mg/dL, 90.4 mg/dL, 25.8/25.5 IU/L, 14.5 g/dL, respectively. After attending nutrition classes, the daily intakes of energy, plant protein, plant fat, carbohydrate, crude fiber, and cholesterol increased significantly. The scores for nutrition knowledge, nutrition attitude, and self-satisfaction also increased after nutrition classes, but there were no significant differences. Percent body fat decreased significantly after nutrition classes. In conclusion, nutrition education for elementary students is effective for the prevention and control of obesity. Further research is needed to develop a systematic program of nutrition education for obese children.

The purpose of the study was to investigate the status of the nutritional education program on educational perception, facilities, contents and systems, which were focused on the school obesity education in the elementary school. A five point Likert scale was used to evaluate the importance and performance of each item in four sections of the survey and Importance-Performance Analysis (IPA; gap between importance and performance) matrix analysis was applied to determine improvement priority. The findings from IPA matrix analysis are in the following. The items of the sections to be improved intensively are recognition of parents and in-charge teacher, availability of the education place, preparation of consulting room, preparation of various teaching media, interest of an education program, meal adjustment of overweight children, combination with education and exercise, education for psychological factors, development of scientific and systematic education program and reduction of meal service duty for education. Accordingly, the IPA matrix analysis suggested that an intensive improvement area should be excessively concentrated on for better performance. The regional gap between importance and performance showed significant difference for textbook and diet of overweight children in Kyunggi-Do. There were significant differences for the government perception, dietary habits and food-life education, fast-food education, education for breakfast importance, and education of school meal indication system and method to read food nutrition indication in Chollabuk-Do. As for the age gap between importance and performance, the twenties showed significantly bigger gaps in perception of school dietitians and linking between school meals and diet education. Therefore, more proactive efforts for the education for obesity prevention are necessary to prevent childhood obesity in elementary school and to help children to possess better health throughout their entire lives.
