Underspecification and Defaults in Korean Aspectual Periphrasis

Yeo, Seungju. 2018. Underspecification and Defaults in Korean Aspectual Periphrasis. Studies in Generative Grammar, 28-3, 411-432. This paper proposes a morphosyntactic analysis of grammatical aspect, with two functional heads Asp and Telic dedicated for yielding the array of grammatical aspect patterns observed in Korean. This approach is capable of accounting for why iss-headed periphrases diverge from the other compositionally well-behaving periphrases that maintain a one-to-one correspondence between the aspectual exponents and the resulting grammatical aspect. As opposed to “compositional” aspectual auxiliaries, iss- is neutral and realizes Asp bearing [∘ PERFECT ], an underspecified functional head. This underspecified head is responsible for ambivalence of iss-headed periphrases.
교실 단위 작문 평가에서 활용 가능한 작문 자동 채점 프로그램의 설계 방안에 대한 연구 - 인지공학적 설계 접근과 채점자의 인지 부하 요인을 고려하여 -
김승주 ( Kim¸ Seung Ju ) 청람어문교육학회 2021 청람어문교육 Vol.- No.83
그간 국외에서 개발된 글 단위 작문 자동 채점 프로그램은 교실 단위 작문 평가 상황에서 활용이 제한적이라 알려져 있다. 그 이유는 기본적으로 기존 작문 자동 채점 프로그램의 설계 방식에 기인한다. 이에 본 연구에서는 이를 개선하기 위한 대안으로서 인지공학적 설계 방식에 따라 작문 자동 채점 프로그램을 개발할 것을 제안하고자 하였다. 이에 인지공학적 설계 접근에 따라 채점자의 인지 과정, 그리고 채점 과정에서 채점자인지 부하와 관련한 선행 연구를 살펴본 결과 (1)텍스트 이해 과정, (2)텍스트 평가 과정, (3)평가 결과 정교화 과정 등의 채점 세부 과정별 인지 부하 요소를 탐색하였으며, 이를 바탕으로 채점자의 인지 부하를 경감하기 위해 필요한 프로그램의 주요 기능으로서 (1)주요 내용 요소에 대한 텍스트 자동 분석 및 표시 기능, (2)주요 표현 요소에 대한 텍스트 자동 분석 및 표시 기능, (3)관련 채점 기준 노출 기능, (4)채점 근거 저장 기능, (5)비슷한 수준의 글 검색 기능 등을 제안하였다. 또한 구체적으로 채점 프로그램의 UI/UX 설계 사례를 제안하였다. It is known that the Automated Writing Evaluation(AWE) system developed overseas has limited use in the classroom-based writing assessment situation. The reason is primarily due to the design method of the existing AWE systems. Therefore, in this study, as an alternative to improve this, it was proposed to develop an AWE system according to a cognitive engineering design method. Accordingly, according to the cognitive engineering design approach, the cognitive load factors for each detailed scoring process were extracted by exploring the prior studies on the scorer's cognitive process and the scorer's cognitive load during the scoring process. Also, based on this, the main functions of the program necessary to reduce the cognitive load of the scorer are (1) automatic text analysis and display function for main content elements, (2) automatic text analysis and display function for main expression elements, (3) ) related grading standards exposure function, (4) scoring basis storage function, and (5) similar level text search function were proposed. Finally, a specific design example of the scoring program was proposed.

OBJECTIVES: Few longitudinal studies have explored age-related differences in the relationship between lifestyle factors and cognitive decline. This study investigated lifestyle factors at baseline that slow the longitudinal rate of cognitive decline in young-old (55-64 years), middle-old (65-74 years), and old-old (75+ years) individuals. METHODS: We conducted an 11-year follow-up that included 6,189 older adults from the Korean Longitudinal Study of Aging, which is a cohort study of community-dwelling older Koreans. Lifestyle factors, including physical activity, social activity (SA), smoking, and alcohol consumption were assessed at baseline. Cognitive function was measured at 2-year intervals over 11 years. Latent growth modeling and multi-group analysis were performed. RESULTS: The influence of lifestyle factors on the rate of cognitive decline differed by age. Smoking at baseline (-0.05; 95% confidence interval [CI], -0.11 to -0.00, per study wave) accelerated cognitive decline in young-old individuals, whereas frequent participation in SA at baseline (0.02; 95% CI, 0.01 to 0.03, per study wave) decelerated cognitive decline in middle-old individuals. None of the lifestyle factors in this study decelerated cognitive decline in old-old individuals. CONCLUSIONS: Cognitive strategies based on modifiable lifestyle factors such as smoking cessation in young-old individuals and frequent SA participation in middle-old age individuals may have great potential for preventing cognitive decline. Because the influence of lifestyle factors varied by age group, age-specific approaches are recommended to promote cognitive health.

Purpose: Breast conserving surgery (BCS) is generally not considered for breast cancer because of concerns about the poor prognosis of triple negative breast cancer (TNBC). We assessed the outcomes of BCS and mastectomy for patients with stage II-IIIA TNBC. Methods: The data of 172 breast cancer patients diagnosed with stage II-IIIA TNBC who underwent treatment at Pusan National University Hospital and Pusan National University Yangsan Hospital from 2010 to 2014 were retrospectively analyzed. The patients were divided into the following two groups: patients who underwent BCS (n=101) and those who underwent mastectomy (n=71). The Cox regression model was used to examine the outcomes of both treatments. The median follow-up period was 71 months in the BCS group, and 67 months in the mastectomy group. Results: The median age of the 172 patients was 51 years (range, 22-82 years). In the BCS group, radiation therapy and chemotherapy (p<0.001 and p=0.007, respectively) were performed more frequently. The BCS group had more patients with a high Ki-67 index (p=0.006), while the mastectomy group included more patients with a higher pathologic T (pT) stage (p=0.005). The 5-year loco-regional recurrence-free, disease-free, and overall survival rates of the BCS group versus the mastectomy group were 93.8% versus 95.3%, 89.8% versus 90.7%, and 90.8% versus 86.3%, respectively, but the differences were not statistically significant. Lymphovascular invasion was a risk factor for disease-free survival and advanced stage was an important risk factor for overall survival. Conclusion: In stage II-IIIA TNBC, BCS was not inferior to mastectomy in locoregional recurrence rates, disease-free survival rates, or overall survival rates.

Background: While the formal test has been used to provide a quantitative measurement of core stability, studies have reported inconsistent results regarding its test-retest and intra-observer reliabilities. Furthermore, the validity of the formal test has never been established. Objects: This study aimed to establish the concurrent validity and test-retest reliability of the formal test. Methods: Twenty-two young adults with and without core instability (23.1 ± 2.0 years) were recruited. Concurrent validity was determined by comparing the muscle thickness changes of the external oblique, internal oblique, and transverse abdominal muscle to changes in core stability pressure during the formal test using ultrasound (US) imaging and pressure biofeed-back, respectively. For the test-retest reliability, muscle thickness and pressure changes were repeatedly measured approximately 24 hours apart. Electromyography (EMG) was used to monitor trunk muscle activity during the formal test. Results: The Pearson’s correlation analysis showed an excellent correlation between trans-verse abdominal thickness and pressure biofeedback unit (PBU) pressure as well as internal oblique thickness and PBU pressure, ranging from r = 0.856–0.980, p < 0.05. The test-retest reliability was good, intraclass correlation coefficient (ICC1,2) = 0.876 for the core stability pressure measure and ICC1,2 = 0.939 to 0.989 for the abdominal muscle thickness measure. Conclusion: Our results provide clinical evidence that the formal test is valid and reliable, when concurrently incorporated into EMG and US measurements.

We have used electrochemical deposition method to make CdS thin film and nanostructure. 0.02 M sodium thiosulfate and 0.2 M cadmium aqueous solution were prepared in pH 2.5 and 85 ℃ and we used the nanoimprinting technology for CdS nanostructure. We imprinted polymer resin on ITO/glass and it was used working electrode. From this study, we focus on how well build the CdS window layer on the ITO and on fabricating the CdS nanorods vertically aligned on window layer. Instead of conventional way to build the nanorods, one of the promising techniques, nanoimprinting, would be suggested.
