A Study on Self-reliance and Residential Service Needs of Patients with Chronic Mental Illness / 정신신체의학

OBJECTIVES: Residential services are provided to help patients with chronic mental illness, but those have some problems because of provider focused services and uniformized training. So the purpose of the study was to explore residential needs of patients with the chronic mental illness such as chronic schizophrenia. METHODS: A survey was conducted on 139 mental illness patients using mental health facilities at Ansan city area in South Korea. We investigated their demographic and social characteristics, the degree of self-reliance and residential service needs. RESULTS: More than half of them had the desire for self-reliance, and they needed job support mostly. They were positive about the use of residential facilities and needed daily living skill and social skill training. Also they preferred day rehabilitation in type of facility. And they wanted to operate in a way that they returned home at the weekend after group home. CONCLUSIONS: For facilitating the recovery of patients with chronic mental illness, it would be necessary to provide individualized residential rehabilitation services and to improve existing residential facilities and programs reflected on the patients' needs.

Three dimensional analysis of tooth movement using different sizes of NiTi wire on NiTi scissors-bite corrector / 대한치과교정학회지

OBJECTIVE: The purpose of this study was to compare the difference in three dimensional tooth movement using three different wire sizes (0.018 x 0.025-in, 0.016 x 0.022-in, 0.016-in) on a NiTi scissors-bite corrector. METHODS: Computed tomography (CT) images of the experimental model before and after tooth movement were taken and reconstructed into three dimensional models for superimposition. The direction and the amount of tooth movement were measured and analyzed statistically. RESULTS: The lingual and intrusive movements of the crown of the maxillary second molar were increased as the size of the NiTi wire increased. The roots of the maxillary second molars moved buccally except for the 0.016-in group. The intrusive movement of the roots of the maxillary second molars was increased as the size of the NiTi wire increased. Due to the use of orthodontic mini-implants, anchorage loss was under 0.2 mm on average. CONCLUSIONS: The 0.018 x 0.025-in NiTi wire was most effective in lingual and intrusive movement of the maxillary second molar which was in scissors-bite position. Indirect skeletal anchorage with a single orthodontic mini-implant was rigid enough to prevent anchorage loss.
