Purpose: Sunken eyelid is a deformity of upper eyelid due to atrophy of periocular fat tissue, loss of skin elasticity. It causes the skin retraction of eyelid and unfavorable fold. Sunken eyelid occurs from the results of natural aging process, facial trauma, complication of previous periocular surgery, etc. We acquired a satisfied correction of sunken eyelid and unfavorable fold using autologous fat injection only. The aim of this study is a assessment of autologous fat injection for correction of sunken eyelid accompanied with unfavorable fold. Methods: From August 2002 to March 2006, we performed 37 cases of correction of sunken eyelid with unfavorable fold using autologous fat injection. They were all females with ages ranged from 23 to 63. Fat was harvested from lower abdomen and centrifuged with Coleman system. Multi-layered injection of purified fat was done from orbital fat layer to orbicularis oculi muscle. Results: Overall, improvement of sunken eye and unfavorable fold was observed in the majority of the patients. Discomfort of eye opening was improved in 24 patients. The average injection volume was 1.33 mL in right eyelid, 1.31 mL in left eyelid at first injection. Second injection was done in patients who absorption of injected fat was noted with. No specific complications were observed. Conclusion: Natural and attractive upper eyelid was acquired from fat injection only in sunken eyelid with unfavorable fold. To the authors' knowledge, it is desirable for sunken eyelid accompanied with unfavorable fold to be treated with autologous fat injection at first. Although some shortcomings are substantial, autologous fat injection is easy and effective method for correction of unfavorable fold in sunken eyelid without specific complication.

This paper presents the assessment of 7-wire strand monitoring using acoustic emission technique for bridges. 7-wire strand is widely used construction materials to provide additional tensile force to bridges. PSC (PreStressed Concrete) bridge and cable-stayed bridge are representatives for such cases. However, as the bridge aging progresses recently, corrosion problems of strand are emerging. For this reason, various NDT (Non-Destructive Test) methods for cable inspection are being studied and applied to the field. One of the NDT methods, acoustic emission technique, is known as an effective technique to detect cable damage and breakage. In this study, to evaluate the applicability of acoustic emission technique to bridges, acoustic emission signals according to damage of the strand were acquired and analyzed by tensile test. Moreover, The optimal AE sensor type was selected for field application. As a result, it is considered that the acoustic emission technique will be able to detect corrosion breakage and signs of rupture.

Given that the demand for dental care for elderly individuals is expected to increase according to demographic changes, long-term roadmaps for the current health insurance system should be actively planned. The study aimed to investigate the health insurance system in Korea, compared to that of Japan, and suggest directions for the work of dental hygienists to provide basic data on efficient improvements in the health insurance system. Based on the collected data, the website was used to collect additional related data from Korea and Japan. The most common cause of death in Korea was malignant neoplasms, and most patients were hospitalized for diseases and disorders of the musculoskeletal system and connective tissue. Dental care covered by Korean medical insurance for individuals aged 65 years or older was treatment oriented, such as dentures and implants, while in Japan, treatment-intensive items, such as visiting a dental hygienist for guidance and provision of home-care professional oral hygiene treatment, were covered. The percentages of remaining teeth in Korea and the percentage of remaining 20 teeth were 68.9% in those aged 65 to 74 years and 51.2% in those aged 75 to 84 years in Japan. A strategy for promoting oral health among elderly individuals should be established, and a multilateral intervention approach is required to prevent oral problems from leading to deterioration of whole-body health. The role of dental hygienists in providing comprehensive assessment to elderly individuals is important. In order to provide systemic oral care, it is necessary to introduce oral care systems according to the national policy.

Recently, construction companies prefer to use large scale system forms to prepare for lacking of skilled workers, aging and the chances of application of pre-build&post-sale policy. In result of the effort and interest, the duration for framework of domestic high rise buildings has been accomplished to 3-4days per floor but for the apartment housing which form over 90% of the domestic construction industry, and especially the middle story RC apartments which is the main part, the duration for framework is only about 6-8days per level. This is only about 50% of the duration per level of RC residential buildings in North America. In previous researches elementary technology, which has potential of duration reduction, was proposed and this research suggest the applicability in construction sites and ways to improve it using elementary technology applied Mock-up Test. Furthermore, we analyze the productivity and T/C usage rate of the 6day-Cycle and suggest an improved model.

BACKGROUND/OBJECTIVES: Since gain or loss of skeletal muscle mass is a gradual event and occurs due to a combination of lifestyle factors, assessment of dietary factors related to skeletal muscle is complicated. The aim of this study was to investigate the changes in total energy intake according to the level of skeletal muscle mass. SUBJECTS/METHODS: A total of 8,165 subjects ${\geq}30years$ of age from the Korean National Health and Nutrition Examination Surveys (KNHANES) 2008-2011 were included in the analysis, and multivariate-adjusted regression analyses were performed to analyze the association of the quartiles of sarcopenia index (SI) with energy intake of the study population after adjusting for age and metabolic parameters. RESULTS: The increase in SI quartile was in proportion to the gradual decrease in systemic lipids and the anthropometric measurement of fat accumulation (P < 0.001). Subjects in higher SI quartiles tended to consume more total energy and energy-producing nutrients than those in lower quartiles (P < 0.001). After age, body weight, alcohol consumption, and metabolic parameters were adjusted in the analysis, total energy intake gradually increased according to the increase in SI quartile, and the association between total energy intake and SI was more pronounced in men. However, the risk (odd ratio) of having a low SI was not affected by any single macronutrient intake. CONCLUSION: In this study, total energy intake was positively associated with SI and relative skeletal mass in both men and women. However, no significant association or a weak association was observed between any single macronutrient intake and skeletal muscle mass. The data indicated that acquiring more energy intake within the normal range of energy consumption may help to maintain skeletal muscle mass.

As the aging society is accelerated, the population with dementia grows significantly faster. Because there is no complete cure of dementia, it is of great importance to detect the disease at a very early stage and prevent its fast aggravation through evaluation of MCI(Mild Cognitive Impairment) which happens before dementia. The current assessment of MCI conducts only in the form of hand-written data and by 1:1 face to face communication between the subjects and the examiners. Due to this, both examiners' fatigue rate and evaluation error rate increase. Further, there are some limitations in utilizing and analyzing data collected. Against the problems, therefore, there is a need to develop a computerized system by which MCI is assessed, and the results are saved and analyzed. This paper presents the development of such a system enabling MCI evaluation, its related data collection and analysis.

Background: The global population is aging rapidly, and accordingly, the number of patients with dementia is increasing every year. Although the need for dental treatment increases for various reasons in patients with dementia, they cannot cooperate during dental treatment. Therefore, behavioral management, including sedation (SED) or general anesthesia (GA), is required for patients with dementia. Thus, this study aimed to investigate the trends and effects of SED or GA in patients with dementia undergoing dental treatment in South Korea based on the Korean National Health Insurance claims data. Methods: This study utilized customized health information data provided by the Health Insurance Review and Assessment Service. Among patients with records of using sedative drugs during dental treatment from January 2007 to September 2019, patients with the International Classification of Diseases-10 code for dementia (F00, F01, F02, F03, and G30) were selected. We then analyzed the full insurance claims data for dental care. Age, sex, sedative use, and dental treatment of patients were analyzed yearly. In addition, the number of cases of GA or SED per year was analyzed, and changes in behavioral management methods with increasing age were investigated. Results: Between January 2007 and September 2019, a total of 4,383 (male, 1,454; female, 2,929) patients with dementia received dental treatment under SED or GA. The total number of SED and GA cases were 1,515 (male, 528 ; female, 987 ) and 3,396 (male, 1,119 ; female, 2,277) cases, respectively. The total number of cases of dental treatment for 4,383 patients with dementia was 153,051 cases, of which 2.22% were under GA and 0.98% were under SED. Midazolam was the most commonly used drug for SED. Conclusion: Although gingivitis and pulpitis were the most common reasons for patients with dementia to visit the dentist, GA or SED for patients with dementia was frequently used in oral and maxillofacial or periodontal surgery.

This study aims to present the need to supplement the driver's license renewal test for elderly drivers. In Korea, the proportion of elderly drivers is increasing as the elderly population increases rapidly. Overall the traffic accident rate is decreasing but the traffic accident and death rate from traffic accidents are increasing in older drivers. In this study the assessments and education conducted when renewing the driver's license for elderly drivers conducted in Korea were conducted to find out the necessary tests compared to the current situation of foreign countries. Although it is appropriate to evaluate the three key functional areas of vision, cognition, motor and somatosensory, we currently evaluate visual acurity in vison area. While MMSE-K and Clock drawing tests are not recognizable for mild cognitive impairment in cognitive areas. The motor and somato sensory function to perform driving are not evaluated at all. Therefore for safe driving of older drivers, the test to be conducted during renewal of the driver's license will need to supplement that the visual field and contrast sensitivity in vision area, cognitive function from mild cognitive impairments, and the endurance, functional range of motion and proprioception in motor function area.
