Background: Although coronavirus disease 2019 is causing a variety of psychological problems for workers, there are few longitudinal studies on changes in workers' mental health by workplace intervention. This study aimed to evaluate the change in the prevalence of depression and anxiety according to the active involvement of the workplace. Methods: This study was conducted on 1,978 workers at a workplace who underwent a health screening from January 2019 to August 2020, and classified depression and anxiety disorders using a self-report questionnaire. After the first pandemic, the company stopped health screening, took paid leave and telecommuting, and conducted interventions such as operating its own screening clinic. To see if this workplace intervention affects workers' mental health, we conducted generalized estimating equations to compare odds ratio (OR). Results: In the pre-intervention group, 384 people (16.86%) had depression, and 507 people (22.26%) had anxiety disorder. Based on the OR before intervention, the OR of depression decreased to 0.76 (0.66-0.87) and the OR of anxiety disorder decreased to 0.73 (0.65-0.82). Conclusions: As a result of this study, it was confirmed that workplace intervention was related to a decrease in depression and anxiety. This study provides basic data to improve workers' mental health according to workplace intervention, and further research is needed according to workplace intervention in the future.

Purpose: We sought to evaluate the effectiveness of bone substitutes in circumferential periimplant defects created in the rabbit tibia. Methods: Thirty rabbits received 45 implants in their left and right tibia. A circumferential bone defect (6.1 mm in diameter/4 mm depth) was created in each rabbit tibia using a trephine bur. A dental implant ($4.1mm{\times}8.5mm$) was installed after the creation of the defect, providing a 2-mm gap. The bone defect gaps between the implant and the bone were randomly filled according to the following groups: blood clot (CO), particulate Bio-Oss$^{(R)}$ (BI), and Bio-Oss$^{(R)}$ Collagen (BC). Ten animals were euthanized after periods of 15, 30, and 60 days. Biomechanical analysis by means of the removal torque of the implants, as well as histologic and immunohistochemical analyses for protein expression of osteocalcin (OC), Runx2, OPG, RANKL, and TRAP were evaluated. Results: For biomechanics, BC showed a better biological response ($61.00{\pm}15.28Ncm$) than CO ($31.60{\pm}14.38Ncm$) at 30 days. Immunohistochemical analysis showed significantly different OC expression in CO and BC at 15 days, and also between the CO and BI groups, and between the CO and BC groups at 60 days. After 15 days, Runx2 expression was significantly different in the BI group compared to the CO and BC groups. RANKL expression was significantly different in the BI and CO groups and between the BI and BC groups at 15 days, and also between the BI and CO groups at 60 days. OPG expression was significantly higher at 60 days postoperatively in the BI group than the CO group. Conclusions: Collectively, our data indicate that, compared to CO and BI, BC offered better bone healing, which was characterized by greater RUNX2, OC, and OPG immunolabeling, and required greater reversal torque for implant removal. Indeed, along with BI, BC presents promising biomechanical and biological properties supporting its possible use in osteoconductive grafts for filling peri-implant gaps.

The data were analyzed with descriptive statistics, paired t test, and McNemar test by SPSS pc program. The results were as follows ; 1. Mean age of th subjects was 27 and most subjects graduated from the high school and the college. 80.3% of the subjects had nuclear family. 82.5% of the subjects were full time housewives. 2. 85.8% of the subjects were ipara. Though 71.6% of the subjects might have antepartal care in the clinic, 67.2% of the subjects had no chance to participate in the childbirth class before this study. 3. Subject's health and lifestyle, especially related to eating habits, were changed in the antepartum period. We found that the pregnancy affected positively on health and lifestyle of the women. Over 75% of the subjects became to understand the progress of labor, breath methods during the labor, and perineal exercise. Most subjects changed to think that they could control their body more actively and positively during the labor after participating in the childbirth class. 93.4% answered that 'childbirth class was necessary and important'. Most subjects wanted to be taught the contents, such as postpartum care, breast feeding, and infant care in the childbirth class. In conclusion, pregnant women to attend the childbirth educational program with their husband, and the 2-hour childbirth class provided by the researchers very effective in many aspects. Therefore we anticipated that the childbirth class on basis of pregnant women's needs will contribute to improvement of pregnant women's health and well-being during the labor.

In order to investigate the relation of subjective complaints to objective course of treatment in pulmonary tuberculosis, one hundred and seventy four cases registered at the University Health Center in Chonnam University were divided into two groups, complaint group and non-complaint group. By analysing the record at the University Health Center during these seven years from 1973 to 1979, following results were obtained: 1. In complaint group who had subjective symtoms, thirty eight cases(77.6%) among forty nine cases were detected. at clinic visit. In non-complaint group who had not any symtoms, one hundred and twenty one cases (96.8%) among one hundred and twenty five cases were detected at compulsive physical examination. 2. Comparisons of complaint group with non-complaint group were not statistically significant in many aspects, but significantly higher cases were discharged at the University Health Center to receive other medical service in complaint group than in non-complaint group. (6.1% vs 0.8%, respectively) On the contrary, non-complaint group refused medication more than two times compared with complaint group in the course of treatment (29.9% vs 12.2%, respectively). 3. In the average time lag from initial diagnosis to initial treatment, comparisons between complaint vs non-complaint group were significant (7.8 vs 28.3 days, respectively). 4. Subjective symptoms were thought to create motivation to receive therapy, and influence of motivation to therapy was strong at initial stage but it become weaker as time passed.
