The picosecond laser has been widely used to remove tattoos, and improve wrinkles, acne scarring, and pigmented scars. This study was performed to investigate the efficacy and safety of a 1,064-nm fractional picosecond laser treatment for depressed traumatic scars. A total of twenty Korean patients with depressed scars were treated with a 1,064-nm fractional picosecond laser at a two-week interval with a spot size of 3 mm, fluence of 3.5 to 5.5 J/cm², and frequency of 2 Hz with a combination of microlens arrays. At 4 weeks after the final treatment, there was a statistically significant improvement in the modified Vancouver Scar Scale (mVSS) and the patient satisfaction score without any significant complication. A 1,064-nm fractional picosecond laser treatment is a safe and effective method to improve traumatic wound scars with depression.

Rotator cuff tear is the most common cause of shoulder pain in middle-age and older people. Arthroscopic rotator cuff repair (ARCR) is the most common treatment method for rotator cuff tear. Early postoperative pain after ARCR is the primary concern for surgeons and patients and can affect postoperative rehabilitation, satisfaction, recovery, and hospital day. There are numerous methods for controlling postoperative pain including patient-controlled analgesia, opioid, interscalene block, and local anesthesia. Regional blocks including interscalene nerve block, suprascapular nerve block, and axillary nerve block have been successfully and commonly used. There is no difference between interscalene brachial plexus block (ISB) and suprascapular nerve block (SSNB) in pain control and opioid consumption. However, SSNB has fewer complications and can be more easily applied than ISB. Combination of axillary nerve block with SSNB has a stronger analgesic effect than SSNB alone. These regional blocks can be helpful for postoperative pain control within 48 hours after ARCR surgery.

The study was conducted to project supply and demand of the physicians from year 1991 to year 2010 based on the analysis of supply and demand of the physicians up to year 1989. Results of the study will provide information for the physicians manpower planning of the 7th 5-year Economic Social Development Planning(1992-1996) and contribute to the overall health manpower planning for the 21the century. It is projected that physician will be oversupplied from the very near future based on the current productivity or underestimated based on the optimal productivity. Thus, it is desirable not to change size of training and education during the 7the 5-year planning period and re-examine the status of the physician manpower at the end of the 7th 5-year period taking into consideration medical services utilization pattern, patients' satisfaction, and physicians' productivity.

One important complication of the tracheostomy procedure is the depressed scar left after the tube is removed. A depressed tracheostomy scar can be aesthetically and functionally unacceptable. Tracheostomy scar treatment aims to fill lost soft tissue volume and correct tracheal skin tug. There are various techniques described to manage post-tracheostomy scars, including the use of autologous tissue or allogenic material and the creation of muscle flaps. In this article, the authors introduce a surgical method using four layers: the scar, the strap muscles, the platysma muscle, and the skin. This procedure has been used in two patients with depressed scar after prolonged tracheostomy placement. The tracheal tug was eliminated in each patient, and an imperceptible cutaneous scar remained. In each case, patient satisfaction was complete. The authors recommend this technique as a simple and effective method of closure for these troublesome tracheostomy scars.

I investigated the relationship between social support, environmental factors, and color design within the public spaces of healthcare facilities. Through a comprehensive literature review and case studies from major hospitals in the United States, the United Kingdom, and Scotland, I explored how these elements contribute to public spaces' overall concept and function. The study emphasizes the need to establish a clear relationship between the social functions of these spaces and their physical and environmental characteristics. By examining theoretical frameworks and observed examples, I analyzed the impact of color design and the integration of internal and external spaces. The findings highlight that well-designed spaces, especially those utilizing effective color schemes and connecting indoor and outdoor areas, enhance user satisfaction and support healing processes. The results underscore the importance of communal spaces in healthcare facilities for psychological and social healing. I conclude that these spaces should be intentionally designed to foster social interactions among patients and visitors by improving pedestrian accessibility and incorporating social support structures.

Although colonoscopy is a routinely performed procedure, it is not devoid of challenges, such as the potential for perforation and considerable patient discomfort, leading to patients postponing the procedure with several healthcare risks. This review delves into preprocedural and procedural solutions, and emerging technologies aimed at addressing the drawbacks of colonoscopies. Insufflation and sedation techniques, together with various other methods, have been explored to increase patient satisfaction, and thereby, the quality of endoscopy. Recent advances in this field include the prevention of loop formation, encompassing the use of variable-stiffness endoscopes, computer-guided scopes, magnetic endoscopic imaging, robotics, and capsule endoscopy. An autonomous endoscope that relies on self-propulsion to completely avoid looping is a potentially groundbreaking technology for the next generation of endoscopes. Nevertheless, critical techniques need to be refined to ensure the development of effective and efficient endoscopes.

This study was conducted to derive factors that affect the satisfaction of home visiting health care services and to develop effective community care models by using the results of Seoul's outreach service which is the basis for Korean community care. The population of the study was the elderly aged 65 and 70 who participated in the Seoul's outreach community services 3rd stage (July 2017 - June 2018) and 4th stage (July 2018 to June 2019). 2,200 people were extracted by the proportional allocation method and home visit interviews were conducted on them. Subjects were divided into sub-groups based on chronic disease prevalence, and logistic regression was conducted to derive factors that affect the satisfaction of home visiting health care services. The results demonstrated that the elderly without chronic diseases were more satisfied when they received health education and counseling services, the elderly with one chronic disease were more satisfied when they received Community resource-linked services. In the case of elderly people with two or more chronic diseases, the service satisfaction level is increased when health condition assessment and Community resource-linked services are provided. Regardless of whether or not they have chronic diseases, service delivery time was a factor that increased satisfaction in home visiting health care. And the degree of explanation understanding was a factor that increased satisfaction for both single and complex chronic patients. Home Visiting health care services based on the community is a key component of the ongoing community care. In order to increase the sustainability and effectiveness of community care in the future, Community-oriented health care services based on the degree of chronic diseases of the elderly should be provided. In order to provide more effective services, however, it is necessary (1) to establish a linkage system to share health information of the subject held by the National Health Insurance Service to local governments and (2) to provide capacity-building education for visiting nurses to improve the quality of home visiting health care services. It is hoped that this study will be us ed as bas ic data for the successful settlement of community care.

The purpose of this Study was to examine the efficacy and compliance of a mandibular advancement device(MAD) according to the severity of sleep apnea in the snorers and obstructive sleep apnea patients. Fifty-four patients (45 males, 9 females, aged 20 - 68years ) who visited Seoul National Uiversity Dental Hospital(SNUDH) to seek for the treatment of snoring and sleep apnea were classified into four groups according to the results of the nocturnal polysomnography and they were instructed to wear MAD regularly which was designed to increase the size of the upper airway by advancing the mandible. The evaluation of the efficacy and compliance of the MAD according to the severity of apnea and the duration after the usage of MAD ( 1week, 1month, 3months, 6months, 12months) was made by using quesionnaires mad in Department of Oral Medicine and Oral diagnosis, SNUDH. The obtained results were as follows : 1. All subjects results were habitual snoreres and 43 patients(79.6%) complained the loudness of snoring that can be heard out of the room. 2. Apnea index(AI) of the total subjects was mean 29.4$\pm$26.9 and respiratory disturbance index(RDI)was mean 37.6$\pm$28.0. And there was nodifference in the efficacy and the compliances of MAD according to the severity of apnea. 3. The severityi of apnea by the questionnaires significantly corresponded with the results of nocturnal polysomnography, and this fact potentiated the diagnostic value of the questionnaire. 4. after the usage of MAD, there was significant improvement in the frequency of snoring, the loudness of snoring, frequency of apnea, daytime sleepiness nad the refreshment after sleep(p<0.001) regardless of the apnea index(AI) and respiratory distrubance index(RDI). 5. The degree of the satisfaction with MAD was mean 74.4$\pm$18.4% and that of the discomfort with the MAD was 31.4$\pm$19.6%. But there was no serious complication in occlusion and temporomandibular joint with the usage of MAD and the duration of the discomfort was mean 3.3$\pm$2.2 weeks. 6. Forty-one patients(75.9%) continued the usage of MAD but thirteen patients(24.1%) stopped the use of MAD because of the discomforts and insufficient results with it.

Purpose: Materials for ear reconstruction are autogeneous cartilage and artificial implants. Despite their potential for donor site complications, autogeneous cartilage frameworks remain the accepted standard for external ear reconstruction. The purposes of this study were to investigate our ear reconstruction cases for 12 years. Methods: During twelve years from January 1996 to December 2008, 70 patients visited our hospital for ear reconstruction of microtia. Among them, 65 cases used autogenous cartilage frameworks, 3 cases used tissue expander and 2 cases used artificial implants. We investigated sex & age, common site, combined malformation, operation methods & their complications, donor site & their complications, anterior chest wall deformity and aesthetic evaluation. Results: Males were affected more often than females. Male to female ratio was 1.8 : 1. The common site of microtia was right ear (72%). And hemifacial microsomia was the most common associated congenital malformation. Surgical techniques included Tanzer-Ruecker method, Tissue-expander and Artificial framework ($Medpore^{(R)}$). Incidence of complication was higher with Tissue-expander & artificial framework than with Tanzer-Ruecker method. But There are few reports of using Tissue-expander & artificial framework and there was no acceptable statistical difference. And costal cartilage was harvested in ipsilateral side and anterior chest wall deformity reported only 2 cases under 10 year-old patients. Other minor complications reported such as, wound disruption and chest wall scar, but without any serious complications. Aesthetic result was evaluated by surgeons and patients for postoperative satisfaction and clinical evaluation. Conclusion: In ear reconstruction of microtia patient, delicate surgical strategy is important for natural shape and maintenance of postoperative contour. However, many methods were introduced for reconstrucion of microtia, the authors reconstructed an auricle in Tanzer-Ruecker method, Tissue-expander and Artificial famework ($Medpore^{(R)}$) for 70 patients. In our study, we generally chose Tanzer-Ruecker method and this treatment modality was satisfactory for patients and the postoperative result was acceptable for surgeons.
