수계 뿜칠형 고무 아스팔트 방수재의 시공성 및 재료적 특성에 관한 연구
김수련,이원헌,오상근,안상덕 대한건축학회 2001 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.21 No.2
There are many problems in application of waterproofing such as quality insurance of over-lap of waterproofing sheets and delay of construction term because of hardening time of paste type being taken long time to get dried, comparing spray type with paste type in waterproofing membrane coating, and increase of man power because of forming layer of waterproofing by pasting. Therefore, the management of construction quality is suggested in this study by means of estimation its tensile performance and temperature dependency according to injection distance, angle and mix proportion. The management referenced of quality for construction is as follows according to the result of testing. The spray angle referenced : 45° The distance referenced from concrete surface to injection gun : 50㎝ The mix proportion ratio of principal agent and hardener is 4 : 1. The usage of reinforcing fabric : consider direction of elasticity, width, penetration degree.

이 연구는 복지 및 전(全)생애 관점에서 장애인의 삶을 활력적으로 사회통합에 이르게 돕 는 데에 핵심적 역할을 하는 ?자립생활?에 대하여 2000년대 이후부터 현재까지 지원 체계 경 향성을 심층적으로 파악하고 체계화하는 것에 목적이 있다. 이를 위해 2000년부터 2015년까 지의 중증장애인 자립생활지원에 관한 99편의 학위논문과 21편의 학술논문을 분석 대상으로 삼았다. 이 120편의 연구물을 연구주제, 연구대상, 그리고 발간유형 및 연구방법으로 나누어 분류 및 체계화하였다. 결과는 다음과 같다 첫째 연구주제별 동향분석에서 연도별 상위권 주제로는 활동보조서비스, 자립생활에 관한 연구와 하위권 주제는 주택서비스, 이동권서비스 등으로 나타났다. 둘째, 연도별 대상에 관한 동향분석 결과, 총 120편의 논문 중 33편이 장애인이 주체가 아니거나 혹은 장애 유형이 불 분명했다. 이를 제외한 연구 대상으로는 혼합 유형이 가장 많았다. 셋째, 연도별 발간유형의 경우 학위논문이 학술논문에 비하여 3배 많이 발간되었고, 연도별 연구방법은 양적연구, 질 적연구, 혼합연구, 문헌연구 순이었다. 위 결과를 토대로 이 연구에서 중증장애인 자립생활 지원에 관한 연구주제는 주로 활동보 조서비스에 관한 연구가, 그리고 연구대상은 혼합 유형이 가장 많았다. 또한 발간유형은 학 위논문이 중점적으로 연구되었고, 연구방법은 양적연구가 가장 활발히 이루어지고 있음을 알 수 있었다.
Effect of Daily Communication Behaviors on Cognitive and Language Abilities of the Elderly

Purpose: The International Classification of Functioning, Disability, and Health can be utilized to measure individual health. Although ‘activity’ is one of the components of health, no studies have investigated the frequency of participation of the elderly in daily communication activities, such as talking, reading, and writing. We examined the daily communication behaviors of normal elderly subjects and their effects on cognitive and language test performance. Methods: Normal elderly subjects (n = 456) over 60 years old completed a questionnaire on how often they thought that they talked/read/wrote in their daily lives. Also, they were administered the Korean Mini-Mental State Examination, Controlled Oral Word Association Test, Short Form of the Korean version-the Boston Naming Test, and Sentence Comprehension Test. Results: About 50% of the participants reported that they seldom talked, read, and/or wrote daily. The more frequently that the participants reported daily talking, reading and writing, the better they performed on cognitive and/or language tests. Daily writing influenced the test results the most, which suggested that writing behavior was closely related to all four cognitive/language tests. Conclusion: These results suggested that daily active communication behaviors play major roles in the cognitive and language abilities of the elderly.
의미 구어유창성 과제의 실시시간에 따른 경도인지장애 하위유형의 변별력
김수련 한국청각언어재활학회 2018 Audiology and Speech Research Vol.14 No.1
Purpose: Semantic (e.g., animal category) verbal fluency (SVF) tasks are widely utilized to measure subtle cognitive and language impairment caused by aging and neurological diseases. Mild cognitive impairment (MCI) regarded as transitional stage in aging with increased risk of incident dementia might show differential performances on SVF tasks according to MCI subtypes and different administration time. Methods: Three MCI subtypes of amnestic single-domain MCI (asMCI), amnestic multi-domain MCI (amMCI), non-amnestic MCI (non-aMCI), and age- and education-matched normal elderly (NE) participated in this study. Both the SVF tasks with 60- and 30-second administration time were conducted to four groups. Results: In 60-second SVF tasks, patients with amMCI and non-aMCI exhibited significantly lower performances than NE, but asMCI did not. In contrast, no significant differences were observed in 30-second SVF tasks between the groups. In receiver operating characteristics (ROC) curve analysis, 60-second SVF task showed fair discriminant power between amMCI and NE [area under ROC curve (AUC) = 0.779] as well as between non-aMCI and NE (AUC = 0.733). Conclusion: The results indicated that subtle cognitive decline of MCI might not be revealed during short administration time because automatic access for lexico-semantic process during the initial phase of SVF task is relatively preserved. The present study suggests that 60-second SVF tasks are useful to differentiate amMCI and non-aMCI groups from NE, but not asMCI.
