Background: Golf is a popular sport involving overhead activity and engagement of the rotator cuff (RC). This study aimed to determine to what level golfers were able to return to golf following RC repair, the barriers to them returning to golf and factors associated with their failure to return to golf. Methods: Patients preoperatively identifying as golfers undergoing RC repair at the study centre from 2012 to 2020 were retrospectively followed up with to assess their golf-playing status, performance and frequency of play and functional and quality of life (QoL) outcomes. Results: Forty-seven golfers (40 men [85.1%] and 7 women [14.9%]) with a mean age of 56.8 years met the inclusion criteria, and 80.1% were followed up with at a mean of 27.1 months postoperatively. Twenty-nine patients (76.3%) had returned to golf with a mean handicap change of +1.0 (P=0.291). Golf frequency decreased from a mean of 1.8 rounds per week preinjury to 1.5 rounds per week postoperatively (P=0.052). The EuroQol 5-dimension 5-level (EQ-5D-5L) index and visual analog scale (EQ-VAS) score were significantly greater in those returning to golf (P=0.024 and P=0.002), although functional outcome measures were not significantly different. The primary barriers to return were ipsilateral shoulder dysfunction (78%) and loss of the habit of play (22%). Conclusions: Golfers were likely (76%) to return to golf following RC repair, including mostly to their premorbid performance level with little residual symptomatology. Return to golf was associated with a greater QoL. Persistent subjective shoulder dysfunction (78%) was the most common barrier to returning to golf.

Background: This study aimed to assess the outcomes of patients with complex rib fractures undergoing operative or nonoperative management at our major trauma center. Methods: A retrospective review of all patients who were considered for surgical stabilization of rib fractures (SSRF) at a single major trauma center from May 2016 to September 2022 was performed. Results: In total, 352 patients with complex rib fractures were identified. Thirty-seven patients (11%) fulfilled the criteria for surgical management and underwent SSRF. The SSRF group had a significantly higher proportion of patients with flail chest (32 [86%] vs. 94 [27%], p<0.001) or Injury Severity Score (ISS) >15 (37 [100%] vs. 129 [41%], p<0.001). No significant differences were seen between groups for 1-year mortality. Patients who underwent SSRF within 72 hours were 6 times less likely to develop pneumonia than those in whom SSRF was delayed for over 72 hours (2 [18%] vs. 15 [58%]; odds ratio, 0.163; 95% confidence interval, 0.029-0.909; p=0.036). Prompt SSRF showed non-significant associations with shorter intensive care unit length of stay (6 days vs. 10 days, p=0.140) and duration of mechanical ventilation (5 days vs. 8 days, p=0.177). SSRF was associated with a longer hospital length of stay compared to nonoperative patients with flail chest and/or ISS >15 (19 days vs. 13 days, p=0.012), whilst SSRF within 72 hours was not. Conclusion: Surgical fixation of complex rib fractures improves outcomes in selected patient groups. Delayed surgical fixation was associated with increased rates of pneumonia and a longer hospital length of stay.

School's preservation of health aims at the promotion of efficiency for school education as it promotes students and all teaching staffs' health. In this study, 26 elementary schools in seoul were selected and analyzed, in order to make a basic plan of efficient public health room where students and all teaching staffs can be actively treated their physical and mental problems. The basic direction of school health was referred to promote school's preservation of health. A public health room should have each necessary field to do their own parts. Besides, its space plan has to be designed in detail so that the room can be convenient and comfortable. Unlike until now, we need to change our mind into planing a public health room apart from a school plan.

Dental plaque has been considered as one of the major causes of inflammation. Therefore, removal of dental plaque by tooth brushing is the most important to prevent gingival and periodontal diseases and to maintain postoperative gingival health. The author executed clinical examination on 100 outpatients who were admitted to infirmary of dental college, S.N.U. The patients were examined on their tooth brushing method, frequency, habit and admitted experience to dental clinic. The obtained results were as follows; 1. The patient group who brushed with the method of Stillman, showed the lowest plaque index. 2. The examined group who brushed more frequently per a day, showed the tendency of reduced plaque index. 3. Plaque index was lowest in the group who brushed after meals and before bed. 4. The patient group who visited more frequently to dental clinic, showed the lower tendency of plague index. 5. Among the total examined group, those who recognized the importance of oral hygiene were less than 10%.

The authors observed the out-patients of Infirmary of the College of Dentistry, Seoul National University, by their age, sex, occupation and chief complaints. The results were as follows : 1. 51.60% of the out-patients were male and 48.40% female. 2. An absolute majority of the out-patients had their dwelling in the Special City of Seoul, their percentage being 92.78% 3. 47.54% of the the out-patients were the unemployed, 26.23% Students, 8.49% clerks and 6.03% merchants. 4. The out-patients who required for surgical treatment at the department of oral surgery were dominant in numbers their percentage being 31.86. 5. The age group of 21-25 which belongs to young adult group was dominant in number with its percent age of 21.82.

Statement of problem : IPS Empress2 system was developed and used in prosthodontic treatment, but the cost of ingot is expensive for wide application. Purpose : This study was to investigate the possibility on recycling of IPS Empress 2 ceramic for wide application of IPS Empress 2 ceramic in prosthodontic treatment. Material and Method : 1st, 2nd and 3rd pressed disc-shaped($10{\times}1.5mm$) IPS Empress 2 specimens were made with IPS Empress ingot(200, Ivoclar, Liechtenstein) and pressing furnace(IPS Empress EP 500, Ivoclar, Liechtenstein). Vicker's surface hardness and fracture toughness, acid resistance, and pressing accuracy of IPS Empress 2 ceramic were measured and analyzed. Surface hardness was measured by microhardness tester(MTX 70. Matsuzawa, Japan), before and after surface treatment with 0.5% hydrofluoric acid and carbonic acid(Coca cola) for evaluation of acid resistance. Results : The surface hardness of 1st pressed specimen was the higher(5.11 GPa) than those of 2nd pressed(4.89 GPa) and 3rd pressed specimen(4.86 GPa), and the fracture toughness of 1st pressed ($1.58MPam^{1/2}$) and 2nd pressed specimen($1.51MPam^{1/2}$) were higher than that of 3rd pressed specimen($1.39MPam^{1/2}$). The changes of surface hardness of 1st, 2nd, and 3rd pressed specimens after treatment with fluoric acid were 0.17, 0.06, 0.05 (GPa) respectively, and those of 1st, 2nd, and 3rd pressed specimens after treatment with carbonic acid were 0.07, 0.00, 0.05(MPa) respectively. The pressing accuracy of 1st,2nd and 3rd specimen were 77.22%, 85.681%, and 75.05%. The pressing accuracy of 2nd pressed specimen was higher than that of the 3rd specimen. Conclusion : The changes of physical properties according to recycling of IPS Empress 2 from this study were insignificant. Therefore the possibility of recycling of IPS Empress 2 can be suggested from the results.
