This study evaluated the voice of 68 normal children and 50 children with palatine tonsil and adenoid hypertrophy with MDVP to examine the hypothesis that their mouth breathing makes the vocal folds dry and this condition contributes to lower the level of voice quality. The results showed that children with palatine tonsil and adenoid hypertrophy had statistically significant elevations in Jitt, RAP, PPQ, Shim and APQ parameters, and had the lower level of voice quality. Therefore, the children with palatine tonsil and adenoid hypertrophy need vocal hygiene education.

최근 세계 자동차업계는 구조개편과 혁신을 동시에 추진하고 있다. 미국 빅 3의 회생을 위해 미국 정부가 직접 나서서 구조조정을 독려하고 있으며, 유럽의 소형차 업체인 폭스바겐과 피아트는 세계 1위와 2위 자리를 목표로 인수합병에 적극 나서고 있다. 일본 지동차업계도 감원을 최소화하면서 대대적인 비용절감을 추진하고 있다. 여기에 중국정부는 자국 자동차산업에 대한 통제와 지원을 강화하면서 추격 전략에서 선도 전략으로 육성 전략을 전환하고 있다. 이러한 가운데 산학관 협력을 통한 자동차업체간 첨단 기술 개발 경쟁도 심화되고 있다. 적자에 허덕이고 있는 자동차업계를 지원하기 위해 각국 정부가 대규모 구제 금융과 연구개발 보조금을 지원하고 있기 때문이다. 이하에서는 가시화되고 있는 세계 자동차산업의 구조개편과 혁신 전략에 대해 살펴보고 타이어업계에 대한 시사점을 도출해 보기로 한다.

Extramedullary plasmacytoma(EMP) is a rare tumor that originates as a clone of malignant transformed plasma cells. EMPs make up 4% of all plasma cell tumors and 90% of EMP cases occur in the head and neck area. The diagnosis of EMP is based on the morphologic and immunophenotypical finding of a localized collection of monoclonal plasma cells in the absence of plasma cell proliferation elsewhere. Patients with EMP can be treated by surgery or radiotherapy alone or in combination. EMP has good prognosis but long-term follow-up is critical because local recurrence or systemic progression to multiple myeloma may develop more than 30 years after the initial diagnosis of EMP. We report a case of EMP in palatine tonsil of 21-year old man who was treated successfully by radiotherapy alone.

Basaloid squamous cell carcinoma(BSCC) is a high-grade variant of squamous cell carcinoma, with a prediction for multifocal involvement of the base of tongue, pyriform sinus, supraglottic larynx, hypopharynx and palatine tonsil. It primary affects men in the seventh decade of life with frequent cervical lymph-node metastasis at presentation. Grossly, these tumors are usually firm to hard, with associated central necrosis, occuring as exophytic to nodular masses. Histologically, the this infiltrating tumor offers a variety of growth patterns, including solid, lobular, cribriform, cords, trabeculae, nests and glands or cyst. We present a 55-year-old female who was treated with surgical excision and radiotherapy. She was firstly presented as a recurrent inflammatory neck mass and finally diagnosed with basaloid squamous cell carcinoma in the palatine tonsil.

Purpose: The aim of this study was to determine the incidence and malignant rate of incidental asymmetric palatine tonsillar uptake (ATU) on $^{18}F$-FDG PET/CT in various clinical indications and to evaluate the clinical and PET/CT findings suggesting malignancy. Materials and Methods: We retrospectively reviewed a total of 2,901 patients ($58.4{\pm}12.3$ yrs, range 20~88 yrs, M:F = 1,841:1,060) who underwent $^{18}F$-FDG PET/CT during an 1-year period with various indications except primary tonsillar cancer and lymphoma evaluation. On $^{18}F$-FDG PET/CT, metabolic abnormality of the palatine tonsil and cervical lymph node were visually assessed. ATU was defined as increased palatine tonsillar uptake with diffuse, focal, or irregular pattern compared to contralateral side. The incidence and malignant ratio of ATU were evaluated according to clinical and PET/CT findings. Results: Of 2,901 cases, 290(10,0%) showed ATU. The incidence of ATU showed seasonal variation and was high in the winter (12.1%). Of 209 cases with ATU confirmed pathologically and/or clinically, five (2.4%) were malignant lesions. ATU with irregular uptake pattern (2/2) and in cases referred for cervical lymph node metastasis of unknown origin (3/5) were frequently associated with malignant lesion (p<0.05). Conclusion: ATU was not infrequently observed on $^{18}F$-FDG PET/CT, and the malignant risk of ATU was low. However, ATU with cervical lymph node metastasis or with irregular pattern on PET/CT would be further evaluated by the histopathologic examination.

In this study, we examine the case of administrative reorganization centered on the case of specific region C and try to clarify implications for the reorganization of administrative district in Korea. The target city for the study is composed of two surface units and one town area. Is it right to integrate these areas into a single administrative district with a huge megapolis, a new city? Or is it right to separate it? This study has begun with these questions. In this study, we conducted a literature review on the theories related to the administrative district reform and examined related issues in the new city area. The policy implications that should be considered in promoting administrative district reform are as follows. First, cooperation and understanding of various stakeholders is needed. Second, the goals and vision of integration should be presented. Third, sufficient review is needed before integration. Fourth, it is important to respect community. Fifth, concession and coordination of interest groups are necessary. Sixth, the administrative reform process must be absolutely democratic and fair.

Adenocarcinoma is a cancer that begins in glandular cells and can occur in several parts of the body. Adenocarcinoma is a rare malignancy of the oropharynx with a few cases reported in the previous report. We describe 1 case of adenocarcinoma of the oropharynx. 46-year-old man was found to have an asymptomatic left tonsil mass and left neck mass that revealed adenocarcinoma by biopsy. A left tonsillectomy and selective neck dissection was performed and pathology confirmed adenocarcinoma with tonsil and neck mass. We report this case with a brief literature review.

Gyeongsangbuk-do moved its provincial office in October, 2015 and has been building a new town with a goal to construct a truly self-sufficient city with the population of 100,000 people before 2027. However, a new town tends to be dualized in terms of its administrative districts, so it is raising a lot of problems regarding from city construction up to operation. In order to solve those problems, this author has selected Si Gun Gu integration that was chosen as a major task to do in 2012 among the basic plans to revise the local administration system announced by the promotional committee to reorganize administrative districts as the range of this research and analyzed how it is going on in Andong-si and Yecheon-gun where a provincial office new town is being constructed. The main contents of this study regard the theoretical model to reform the local administration system, basic plans to revise the local administration system, and necessity and directions for reorganizing administrative districts in Andong-si and Yecheon-gun. Based on that, this author suggests integration of administrative districts as a way for a provincial office new town to establish its identity and grow as a sustainable, new growth focus city in Gyeongsangbuk-do.
