Objectives This study investigated associations between symptom severity and neurocognitive functions in patients with major depressive disorder using comprehensive neuropsychological tests. Methods Ten patients with low depression (LD) and 22 patients with high depression (HD) participated. Symptom severity was determined by both the Beck Depression Inventory and the Hamilton Depression Rating Scale. Additionally, anxiety was measured by the Korean version of the State-Trait Anxiety Inventory (STAI-KYZ). Ten subtests of the Korean-Wechsler Adult Intelligence scale (K-WAIS), Stroop test, the word/design fluency tests were administered to assess cognition. Results The LD and HD groups did not differ in any of cognitive measures but anxiety level. Namely, the HD group obtained significantly higher scores on the state (U = 29.50, p < 0.01) and trait (U = 28.50, p < 0.001) anxiety scales than the LD group. A significant interaction effect between trait anxiety and depression severity was observed on the picture arrangement subtest of the K-WAIS [F (1, 27) = 5.09, p < 0.05]. Conclusions Cognitive deficits observed in patients with major depressive disorder may be related to other factors rather than current symptom severity. Trait anxiety possibly moderates the effect of current symptom severity on social judgment in these patients.

A Corpus-Based Investigation of Intensifier Use by L2 Learners of Korean

황선희(Sun Hee Hwang) 현대문법학회 2023 현대문법연구 Vol.117 No.-

This study aims to investigate the use of Korean intensifiers by L2 learners based on data from a learner corpus. This study focuses on five intensifiers: maywu, cincca, nemwu, toykey, and acwu, which are found to be frequent intensifiers in Korean native speakers’ data. Based on native speakers’ data, it is known that toykey and cincca among those intensifiers are generally used in spoken language while, in general, maywu is rarely used in spoken language. Comparing the Korean Learner Corpus by the National Institute of Korean Language with the Sejong Corpus, this study examines whether L2 learners change intensifiers according to the modes of production (i.e., spoken and written language) and their proficiency levels. Unlike native speakers’ data from the Sejong Corpus, L2 learners overall tend to use far more intensifiers in writing than in speaking. Compared with higher-proficiency learners, lower-proficiency learners, in general, tend to overuse intensifiers. In using toykey and maywu, it is also found that their differences in speaking and in writing get lager as proficiency level becomes higher. These findings indicate that higher-proficiency learners perform in a more target-like way in using an intensifier, and thus suggest that the pattern of native speakers in intensifier use is acquirable.

본 연구에서는 89종의 한국인 상용식품의 총 식이섬유 함량을 AOAC Prosky법으로 측정하였다. 각 식품군의 평균 총 식이섬유 함량을 습량기준으로 구해 보면 곡류 및 그 제품은 4.78±3.55%, 감자 및 전분류는 2.56±1.65%, 당류 및 그 제품은 1.94±0.77%, 두류 및 그 제품은 10.81±6.57%, 종실류 및 그 제품은 9.70±5.92%, 조마료류는 15.38±15.76%, 그리고 음료류는 4.98±4.35%를 함유하고 있었다. 식품별로 보면 곡류 중에서 통보리의 총 식이섬유량이 17.88%로 가장 높았으며, 백미는 0.96%, 현미는 2.75%, 보리쌀은 9.93%이었다. 두류 중에서는 대두, 노란콩과 검정콩이 각각 21.05와 20.42%로 가장 높았으며, 종실류 중에서는 검정깨가 21.34%로 가장 높았다. 조미료류 중에서는 산초가루가 52.43%, 고추가루가 39.37%로 총 식이섬유량이 높았으며, 음료류 중에서는 인스탄트 커피가루가 14.81%로 가장 높았다. 상용식품들의 총 식이섬유 분석치와 식품성분표의 조섬유량을 비교해 본 결과 총 식이섬유 분석치는 조섬유량의 0.12~23.4배 정도되는 넓은 범위를 보였다. 분석된 식품의 총 식이섬유 함량과 우리국민의 식습관을 고려해 보면, 백미 대신 현미를 섭취하고 잡곡의 혼용, 그리고 두류 및 그 가공품의 섭취를 권장하는 것이 식이섬유 섭취를 증가시킬 수 있는 방안이 될 수 있을 것으로 사료된다. Eighty nine common Korean foods were analyzed by the enzymatic-gravimetric method developed by Prosky et al. and adopted by AOAC to determine total dietary fiber (TDF) content. The average TDF content of the foods analyzed was 4.78±3.55% for cereal and grain products, 2.56±1.65% for potatoes and starches, 1.94±0.77% for sugar and sweets, 10.81±6.57% for pulse and pulse products, 9.70±5.92% for nuts and seeds, 15.38±15.76% for seasonings, and 4.98±4.35% for beverages. The foods containing the highest TDF values in the food groups were whole grain barley (17.88%) in cereals, yellow soybean (21.05%) in pulses, black sesame (21.34%) in nuts and seeds, and red pepper powder(39.37%) in seasonings except San Cho powder(52.43%). TDF content of rice, the main staple food of Korea, was 2.75% for brown rice and 0.96% for well-milled rice. The TDF value of the foods analyzed ranged from 0.12 to 23.4 times that of crude fiber reported in the Korean food composition tables. When we consider dietary fiber contents of foods and food consumption patterns together, it is recommended to consume brown rice instead of well-milled rice and increase the consumption of minor cereals and pulses to raise dietary fiber intake.

The purpose of this study is to investigate the effects of task-based craft activities using English storybooks on six-year-old children’s English vocabulary learning, retention and interest. Seventeen children in group A performed craft activities, and 18 children in group B learned the target words using word cards as an after-reading activity. Twelve target words chosen from the three storybooks were tested as a pre-test, a post-test, and a delayed post-test. When the after-reading activities were performed in group A and B, the post-test was administrated and the delayed post-test was administrated two weeks later. The results showed that there were no significant differences between two groups in the pre-test and the post-test. The craft activities and word card activities were equally effective on the vocabulary learning. The result of the delayed post-test, however, showed that there were significant differences between the two groups. The task-based craft activities had a positive effect on children’s vocabulary retention. The qualitative data analysis indicated that children performing craft activities used the target vocabulary in a natural conversation, actively participated in class more, and showed interest in the English craft activities.

[C₁₂mim][TFSI] 용매 내에서 인가 전압이 Alq₃ 결정 성장에 미치는 영향

황선희 ( Sun Hee Hwang ),신동찬 ( Dong Chan Shin ) 조선대학교 공학기술연구원 2022 공학기술논문지 Vol.15 No.1

The effect of voltage on Alq₃ crystal growth in [C₁₂mim][TFSI] was investigated. The additional voltage was applied through 1.0, 3.0, 5.0, 6.0, 8.0, 10.0 V. Cast iron and ITO were used as two electrodes. Microstructure analysis revealed the rod shape of Alq₃. When the applied voltage increases, the population of rod shape phases increases. The XRD analysis showed that the initial phase transited to γ and finally δ phases. The conventional growth methods of the vapor phase and the solution method need a high temperature of over 300 ℃, while the study’s new approaches can lower the heat-treatment temperature to 100 ℃. The phase transition was promoted faster when the applied voltage increased from 0 to 10.0 V. The additional voltage is thought to play a vital role in promoting the phase transition due to lowering the activation energy of nucleation. The phase and shape of OLED materials affect the performance of the OLED device. One can obtain various shapes and phases of Alq3 at a low temperature of 100 ℃, which is a promising technique for OLED material manufacturing. The results also suggest a new academic point of view to understand the nucleation behavior of OLED materials with artificially applied charges.
