Home appliance proposes the experience of new lifestyle to consumers, together with digital technology-applied highly advanced functions, beyond its natural quality like the basic function of reducing the burden of housework. However, under the current circumstances that populations are rapidly aging, the number of elderly consumers, who feel it inconvenient to smoothly use even the basic function of home appliance, is increasing in proportion to populations. Therefore, the necessity for developing home appliance with improved usability in consideration of the elderly is rising up. This study analyzed the elderly's pattern of using home appliance and illustrated the procedure of their using home appliance, putting its focus on the home appliance that the elderly highly depend on in keeping their daily life and that they feel it inconvenient to control. And based on the illustrated procedure, this paper substituted various kinds of home appliance that were not surveyed by this study and found out 4 user behavioral models for home appliance. Same as the concept of universal design, product designs, which are convenient to use by the elderly whose physical functions are reduced, are expected acceptable to various user classes. The found user behavioral models purport to give references to design process for product planning and design solutions.

The purpose of this article was to evaluate the effects of a new upper molar distalization system, the Frog Appliance, on dentofacial structures in a Class II, division 1 patient. An 11-year-old girl was referred to our clinic for orthodontic treatment. She had a mild skeletal Class II malocclusion with Class II molar and canine relationship on both sides. The treatment plan included distalization of the upper first molars bilaterally followed by full fixed appliance therapy. For the upper molar distalization, a new system, the Frog Appliance, was constructed and applied. Lateral cephalometric radiographs were used to evaluate the treatment results. Distalization of the upper first molars was achieved in four months successfully, and Class I molar relationship was obtained. Total treatment time was 16 months. According to the results of the cephalometric evaluation, a nearly bodily distal molar movement with a slight anchorage loss was attained. In conclusion, the Frog Appliance was found to be a simple, ef ective, non-invasive, and compliance-free intraoral distalization appliance for achieving bilateral molar distalization.

Oral appliance therapy is a simple, reversible way for improving snoring and/or obstructive sleep apnea. It may be indicated for the patients who are unable to tolerate continuous positive airway pressure (CPAP) or who have potential risks for surgical intervention. Oral appliance therapy increases airway space by the providing stable anterior positioning of the mandible, pulling out tongue, lifting up soft palate, or changing the muscle activity of the genioglossus. Currently, more than 80 different types of oral appliances have been introduced for snoring and/or obstructive sleep apnea. They are classified by their characteristics such as mode of action, adjustability and material used. This article provides a detailed clinical protocol and treatment procedure for oral appliance therapy.

Objective: This case report describes orthodontic treatment of contracted mandibular arch using a trombone appliance. Methods: A 14-year-old girl with Class II division 2 malocclusion, retroclined maxillary incisors, and buccally displaced maxillary canines required dental expansion in 3 spatial directions to correct the contracted maxillary and mandibular arches. In the initial phase of treatment, the maxillary arch was expanded and distalized using a quad-helix appliance and cervical headgear. Following the expansion and leveling of the maxillary arch, a trombone appliance was used to expand the mandibular arch. On correction of the mandibular arch and provision of sufficient space to level the mandibular teeth, fixed orthodontic treatment phase was initiated. Results: A trombone appliance proved effective in correcting the contracted mandibular arch. Because of labiolingual and transversal expansion, the mandibular dental arch perimeter was increased by 7.4 mm; the misalignment of the mandibular teeth was corrected successfully. Conclusions: A trombone appliance may serve as an appropriate clinical alternative for treating moderate mandibular arch crowding caused by the contraction of the dental arch.

This paper proposed a new diffusion model considering DSM rebate program's support conditions. The proposed method used some aspects of the rebate program such as support qualifications, annual support volume, and support level per appliance as following : The support qualifications were limited as the consumer which can get the rebate program's benefit, the annual support volume was constrained as the fixing budget and the support level per appliance was considered by high-efficient appliance actuality price. This paper also proposed a new method that used neural network as its parameter estimation moth[,4 for the diffusion model. The diffusion model and its parameter estimation method are expected to be able to analyze the diffusion characteristics of high-efficient appliance through the rebate program and the effects of rebate program's support conditions. Also, these will be able to evaluate the impacts and to analyze the cost-effectiveness of Energy Efficiency Demand-Side Management(EEDSM) resources. The case study is performed on the high-efficient lighting appliance rebate program of Korea by using the suggested diffusion model and estimation method and thus verified its validity.

Early orthodontic treatment in growing children requires the removable orthodontic appliances. The removable orthodontic appliance can be used in the primary dentition and mixed dentition. The purposes of use of removable orthodontic appliance in prmary dentition or mixed dentition are the interception of skeletal or dental malocclusion, guiding the normal dentition, and retention after comprehensive orthodontic treatment. Therefore, it is needed to use the removable orthodontic appliance in children with malocclusion. This report presents cases of growing children with skeletal class II and III malocclusion treated with removable orthodontic appliance during mixed dentition and Multiloop Edgewise Arch Wire(MEAW) during permanent dentition. The results obtained through these cases were summarized as follows : 1. Removable orthodontic appliances guide normal dentition and skeletal growth in growing children. 2. Removable orthodontic appliances play an important role in intercepting malocclusion in mixed dentition before use of fixed orthodontic appliance. 3. MEAW can be applied to finishing stage of all cases and is effective in correction of occlusal plane, achievement of interdigitation, and control of dental inclination. 4. It is needed that removable appliances are used during mixed dentition through correct diagnosis and fixed appliance are used in permanent dentition.
