OBJECTIVES: To determine chronological characteristics of vestibular recovery after vestibular neuritis (VN) by using various clinical parameters. STUDY DESIGN: Prospective clinical study. METHODS: Twenty of 22 consecutive patients with acute VN underwent serial follow-ups of static (spontaneous nystagmus, subjective visual vertical, and ocular torsion) and dynamic (head-shaking nystagmus [HSN], vibration-induced nystagmus [VIN], head thrust test, and caloric test) vestibular imbalances for 1 ye

This study provides Class III evidence that, in patients with dizziness, a questionnaire can diagnose BPPV with a sensitivity of 87.0% and a specificity of 89.8%.

Bilaterally abnormal HITs indicate that a patient has a large unilateral CPA tumor. The abnormal HITs in the contralesional direction may be explained either by adaptation or by compression and resultant dysfunction of the cerebellar and brainstem structures. The serial evaluation of HITs may provide information on tumor growth, and thereby reduce the number of costly brain scans required when following up patients with CPA tumors.

본 연구의 목적은 사회연결망 분석을 통해 자생적 교사 연구모임의 특징을 탐구함에 있다. 이에 초등학급경영연구회를 사례로 하여, 교사 연결망의 인적 특징, 구조적 특징, 연결의 특징, 교환 관계의 특징을 살펴보았다. 사회연결망 분석 질문지를 활용하여 분석한 결과는 다음과 같다. 인적 특징 측면에서 볼 때 도움을 제공하는 소수와 도움을 받는 다수가 연구회를 구성하고 있었으며, 잠재적 연결망 형성에 기여하는 구성원이 존재하고 있었다. 구조적으로는 취약성이 잠재된 중앙 집중형 연결망 구조를 가지고 있으며, 도움의 형태에 따라 내부에서 구성되는 연결망은 서로 다른 구조를 띄고 있었다. 연결은 약한 연결이 주를 이루고 있으며 구성원 간의 관계 속에서 교환되는 내용은 구성원들이 도움을 필요로 하는 영역과 거의 일치하고 있었다.

This study analyzes factors that determine the usage of digital information by senior consumers in the mobile environment. Senior consumers are alienated from digital information in South Korea; therefore, there have been increasing attempts to resolve this digital divide and reduce the digital information usage gap between young adults and senior consumers. The study used panel data from the National Information Society Agency (2017); there were 1,463 participants, aged 50-79 years. SPSS 19.0 w

Purpose of review The current review covers recent advances in bilateral vestibulopathy (BVP) in terms of its etiology, diagnosis, and treatments. Recent findings The etiology of BVP depends on its clinical course and associated findings, and genetic abnormalities are increasingly recognized in isolated as well as complicated form of BVP. Recent developments in evaluation of the vestibular function have greatly enhanced the detection of BVP, and introduction of the consensus diagnostic criteria

Importance: Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo with frequent recurrences. Objective: To determine the efficacy of a web-based diagnosis and treatment of BPPV when it recurs in patients with confirmed and treated BPPV. Design, Setting, and Participants: This randomized, controlled, parallel-group, double-blind trial took place in multiple referral-based university hospitals in South Korea between July 2017 and February 2020. Of 728 patients (age ≥20 ye
