Temporomandibular disorders 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. James Costen has mentioned about the relationship between TMD and posterior bite collapse, there have been many controversies about the etiology and comorbidities of TMD. The purpose of this study was to investigate the relationship between TMD and hearing acuity in 158 volunteers with or without TMD symptoms. The subjects were examined clinically about TMJ sound, missing teeth, tinnitus, TMJ pain and masticatory muscle pain and the hearing acuity were measured by Audiometer(ITO AE-1000, Japan). The result of this study indicated that there was no significant differences between TMD symptoms and hearing acuity relatively.

In the present knowledge and information society, knowledge and use of information and communication technology(ICT) is very important for every citizen. Also, for national power of a nation, IT-related industries need to be supported since those industries can be reconstructed in a short period of time unlike other industries. In this sense, identification and education of gifted children in IT become a serious national issue. Since 2013, gifted education has been conducted as a form of convergent education by government policy. However, there have been controversies on convergent education for gifted education. The purpose of this paper is to analyze the usefulness of convergent curriculum for gifted education in IT. For this purpose, gifted children in IT in a gifted education center are analyzed. By comparing the entrance ranking and graduation ranking, it is concluded that the current convergent gifted curriculum may not be efficient.

The purposes of this study are to define 'housing welfare' which constitutes an important theme of discussion today and to present some future policy issues. Recently, the expression 'housing welfare' is widely used in our daily life and written in some laws, but its concept is still ambiguous. Housing welfare can be defined as 'the situation in which citizens gain access to a decent housing and adapt themselves well to the community life. In this context, the goals of housing welfare policy should be as follows: reduction of the number of households living below the minimum standard in housing, promotion of the right to housing, housing provision and management based on housing needs, linkage of housing and other welfare measures, realization of social integration and social justice. But, there are still some controversies on such questions as target group, moral hazard of beneficiaries, social equity, etc. To get all the policy alternatives more effective, efforts should be made to improve the general infrastructure of welfare policies, to prevent NIMBY phenomenon of local actors, and so on.

Molecular imaging strives to visualize processes in living subjects at the molecular level. Monitoring biochemical processes at this level will allow us to directly track biological processes and signaling events that lead to pathophysiological abnormalities, and help make personalized medicine a reality by allowing evaluation of therapeutic efficacies on an individual basis. Although most molecular imaging techniques emerged from the field of oncology, they have now gradually gained acceptance by the cardiovascular community. Hence, the availability of dedicated high-resolution small animal imaging systems and specific targeting imaging probes is now enhancing our understanding of cardiovascular diseases and expediting the development of newer therapies. Examples include imaging approaches to evaluate and track the progress of recent genetic and cellular therapies for treatment of myocardial ischemia. Other areas include in vivo monitoring of such key molecular processes as angiogenesis and apoptosis, Cardiovascular molecular imaging is already an important research tool in preclinical experiments. The challenge that lies ahead is to implement these techniques into the clinics so that they may help fulfill the promise of molecular therapies and personalized medicine, as well as to resolve disappointments and controversies surrounding the field.

The graft infection within the abdomen is a notorious condition, which usually develops serious complications of anastomotic rupture or distal embolism that ended in death. There has been many controversies in the treatment of an aortobiiliac graft infection and varying results have been reported. The authors treated a case of aortobiiliac graft infection after abdominal aortic aneurysm surgery. The operation was performed with re-aortobiiliac bypass using bilateral superficial femoral veins. The result was successful.

Data collected to date indicate that sleep apnea syndrome is a risk factor in the development of cardiovascular dysfunction such as systemic hypertension, cardiac arrhythmias, pulmonary hypertension, right heart failure, angina, myocardial infarction, and stroke. Several reports suggest that untreated patients with sleep apnea syndrome have a higher long-term mortality than treated patients and than normal subjects. But there are many controversies concerning the treatment of sleep apnea syndrome, and there is no universally accepted standard for effective treatment. We reviewed the current approaches and options in the medical treatment of sleep apnea syndrome.

During the last several decades, prognosis of differentiated thvroid cancers improved markedly, mainly due to refinement of surgical techniques and routine use of radioactive iodine. Total or neat-total thyroidectomy is to be performed as the first line of treatment. Routine remnant ablation just after surgery decreases recurrence and increases survival. After then patients are maintained on suppressive dose of thyroid hormone to keep endogenous TSH below normal. Regular follow-up of the patients with serum thyroglobulin measurement and iodine whole body scan after thyroid hormone withdrawal or under recombinant human thyrotropin stimulation select high risk patients with recurrence or metastatic disease and treatment with therapeutic dose of radioactive iodine prolongs survival and sometimes leads cure. Currently recommended diagnostic and therapeutic strategies, present controversies and future directions are discussed.

Carotid body tumor is rare tumor in the neck. Among the pathologic conditions affecting paraganglionic tissue. the carotid body is most frequently involved. There are controversies in terms of natural history. biological behaviors, technique of excision, risks of the operation. Carotid angiography is the most valuable diagnostic aid and important for the planning of therapy. Definite treatment of carotid body tumor is surgical excision. Considerable degree of caution and vascular surgical armamentation are required because of its anatomical location and profuse vascularity. Surgical removal of this kind of paraganglioma must be predicated upon several factors such as tumor character. location. symptom, vascularity, and surgeon's ability.

Elective neck dissection (END), provide proper information on nodal status and stage which are significant prognosticator in head and neck cancers with clinically $N_{(0)}$ neck. But there are many controversies for the extents, methods of surgery, moreover, whether normal lymph nodes, local defencer, have to be removed or not. The authors performed 47 END in 39 patients of head and neck squamous cell carcinoma from 1984 to 1989 and a retrospective study of the cases was conducted. Eighteen percent of nodal metastasis and five percent of extracapsular spread were found in END specimens. We concluded that END provide significant information for the management and evaluation of prognosis in head and neck cancer.

Functional dysphonia (FD) is a voice disorder in the absence of structural or neurologic laryngeal pathology. FD is not a single disease but a disease entity. Therefore several voice disorders, which have completely different pathogenesis, are included in this category. The first step of treatment of FD is differentiating patient's voice symptoms from other organic voice disorders and other functional voice problems. Several different treatment modalities are included in the managements of FD. Voice therapy is in charge of the main role in treatment of FD. Medical treatment is also necessary when patient has general problems which would affect voice production. Vocal folds mucosal lesions can cause FD even the lesion is minor. In this case proper surgical intervention helps to improve the symptom of FD. Psychiatric consultation should be considered when the patient has psychological problems.
