Temporomandibular disorders(TMD) have been defined as a collective term embracing a number of clinical problems that involve the temporomandibular joint, the masticatory muscles, and associated structures. Since Dr. Costen, an otolaryngologist, published his article in 1934 claiming that pain in and around the jaw and "related ear symptoms" improved with alteration of the bite, diagnosis and treatment of temporomandibular disorders(TMD) have been within the concept of occlusion. However most of the modern descriptions for TMD no longer include occlusal disorders within their domain. Despite this trend toward the exclusion of occlusal disorders from TMD domain, the historical linkages between TMD and occlusal therapy are still strong. Currently the most popular theories regarding TMD etiology are based on the biopsychosocial model. In the future, treatment modalities should be directed at the pathophysiological processes of joint and muscle pain as well as the psychosocial aspects of chronic pain.

This study aims to analyze multiple mediating effects of asset and self-esteem on the relationship between disability of household head and life satisfaction. This study used 9th panel data of KoWePS(Korean Welfare Panel Study) and employed path analysis with A-MOS. Research findings of this study are as follows: First, disability of household head had a negative effect on life satisfaction, total assets, and self-esteem. Second, we found not full but partial mediating effects of assets on the relationship between disability and life satisfaction. Third, similarly we found not full but partial mediating effects of self-esteem on the relationship between disability and life satisfaction. Finally, we found multiple partial mediating effects of assets and self-esteem on the relationships between disability and life satisfaction. The findings of this study suggest that financial education as well as asset management targeting persons with disability are necessary and very helpful to sustain their life satisfaction. In addition, we need to think about asset-building programs targeting persons with disability.

This study aimed to make an analysis of the occlusion in the state of muscle fatigue produced by excessive mouth opening and clenching during the dental treatment to control the dental pain and to evaluate the sensory nerve in the muscle pain state. Most of the reasons why patients visit the dental office result in pain-either conceivably the dental origin pain or the non-dental origin pain. The dental offices have many therapeutic actions to produce the masticatory muscle fatigue for the treatment. Dental treatment with long minutes of mouth opening can cause some headaches, masticatory muscle pain and mouth opening difficulties. Patients with mastication problems who visits a dental office to alleviate pain run against another unexpected pain with other aspects. This study uses T-scan II system(Tekscan Co., USA) for the evaluation on the occlusal pattern in the experimental muscle fatigue after clenching, opening the mouth excessively and chewing gum. The occlusal contact pattern is analyzed by the contact timing, namely first, intercuspal, maximum and end point of contact. This inspection was performed at frequencies of 2000Hz, 250 Hz and 5 Hz before and after each experimental muscle pain was produced to 24 subjects who had normal occlusion without the orthodontic treatment or a wide range of the prosthesis by using $neurometer^{\circledR}$ CPT/C(Neurotron, Inc. Baltimore, Maryland, USA). The measuring sites were mandibular nerve experimental muscle fatigue respectively. This study could obtain the following results after the assessment of occlusion and sensory nerve of the experimental muscle fatigue. 1. There were the fastest expression after the excessive mouth opening in muscle fatigue and after tooth clenching in muscle pain. In the visual analog scale that records the subjective level, there was the highest scale after the clenching in the muscle fatigue in jumping off the point of pain. 2. Tooth contact time, contact force, relative contact force on the point of the first contact had no difference, and there were decreases in the contact force after the excessive mouth opening on intercuspal position point, after the excessive mouth opening and the gum chewing on the point of the maximum, and in the contact time after all the experimental muscle fatigue state on the point of the end contact. 3. There was no statistic significance in the current perception threshold before and after the experimental muscle fatigue. 4. There was no significant difference in the contact number, the maximal contact number on the point of the first contact, and the contact number after the mouth opening and gum chewing on the point of the intercuspal position and the contact number after the experimental muscle fatigue on the maximum point, and showed significant decreases. In conclusion, it was found that the occlusal pattern can cause the changes on the case of the clinical muscle weakness by intra-external oral events. It was important that the sedulous attention to details is required during dental treatment in case of excessive mouth opening, mastication and clenching.

악관절 잡음과 동통,과두 흡수를 동반한 퇴행성 측두하악장애는 교합 불안정과 개구장애 를 동반하기도 한다. 진단을 위해 CT나 MRI를 이용해 과두 형태 및 디스크 위치를 파악하 는 것이 유용한 접근법이다. 퇴행성 측두하악관절 환자는 CT나 MRI를 이용하여 진단하고, 과두-원판 재위치와 근 기능 개선을 위해 장기간 교합 안정장치 사용이 필요하므로 교정치료 기간에 변형된 교합 안정장치의 병용이 필요하다. 이에 본 연구에서 교합 안정장치를 병용하여 교합 재구성 증례를 CT나 MRI로 고찰해 보고자 한다.

Achalasia is the disease of nonorganic obstruction of the cardia associated with dilatation of the esophagus, and of unknown etiology characterized by failure of relaxation of the inferior esophageal sphincter and lack of normal peristalsis in the body of the esophagus. This disorder is primarily one of neuromuscular dysfunction, most probably due to a central nervous system lesion with consequent nerve, ganglion and muscle degeneration. The characteristic symptoms are dysphagia, regurgitation and epigastric pain etc. We have experienced a case of Achalasia in 43 aged female with good results by daily mercury bougienage.

The purpose of this research was to examine the factors affecting motivation for change of injured workers. Data from 305 injured workers were anlayzed using hierarchical regression Factors associated with injured workers' motivation for change were: multiple psychological security, acceptability of injury, and independence at personal level, family support at family level, and perceptive severity of injury, job, and return to job.

The current social service delivery system for people with disabilities has four critical problems: absence of needs assessment, absence of case management, shortage of professional workers, and absence of local social welfare agencies. The Ministry of Health, Welfare, and Family of Korea has pushed forward with a project to reform the welfare infra-structure for people with disabilities since 2007. It's main purpose is to reorganize the social service delivery system for people with disabilities. A report from the project makes two suggestions: introduction of new standards for disability and set-up of disability service determination centers. The new standards for disability are suggested to include a work ability test and a welfare needs assessment tool as well as a medical standard. Three models for disability service determination centers are suggested: independent model, local governmental model, and public corporational model. Tentative operations using the three models are on the way in the second half of 2008. In order to reform the social service delivery system for people with disabilities, this study makes a fundamental suggestion: set-up of about 120 local welfare agencies over which the Ministry of Health, Welfare, and Family can have direct control, and which are equipped with professional workers who are able to perform needs assessment and case management. In actuality, welfare centers for disabled people are the best options for local welfare agencies for disabled people.

산업현장에 있어서 기계화의 확산에도 불구하고, 과도한 인력운반(manual materials handling, 이하 MMH)작업으로 인해 발생되는 근골격계 질환(musculo- skeletal injuries, MSls)은 여전히 작업시간의 손실, 비용 증가, 그리고 신체 장애를 야기하는 중대한 원인으로 대두되고 있다.(중략)
