한국어능력시험(TOPIK) 읽기 텍스트의 난이도 연구 -TOPIKⅡ의 읽기 영역을 중심으로-
신정하 ( Jungha Shin ) 이중언어학회 2016 이중언어학 Vol.62 No.-
The goal of this paper is to measure the difficulty of reading texts on the TOPIK (Test Of Proficiency In Korean) in order to examine the distribution of text difficulty among the TOPIK`s various test items. After the 35th TOPIK was administered, the test underwent reforms. It is necessary to examine text difficulty between test items on the reformed test. First, the difficulty texts appearing on the TOPIK are compared to Korean textbooks. The comparison targets consist of three Korean textbooks from level 3 to level 6. Text difficulty is measured by looking at the level of vocabulary, sentence length, and the difficulty of verbal endings. The programming language R was used for text analysis. The results show that the vocabulary found on the TOPIK is at a higher level of difficulty than that found in Korean textbooks. However, the TOPIK`s sentence length and verbal endings difficulty are at a similar level when compared to the Korean textbooks. Second, four tests made available on the TOPIK website (the 35th, 36th, 37th, and 41st) are analyzed. This was done to determine the reliability of the test. The difficulty of text items from one test to another is very important affects the difficulty of the overall test itself. The results show no major difference between the four available tests. Therefore, the reformed TOPIK be considered to have a high level of reliability.

본 연구의 목적은 캠프 프로그램에 참가한 소방공무원의 스트레스, 우울, 외상후 스트레스의 변화를 전향적으로 조사하여 캠프 프로그램의 효과를 검증하고, 스트레스 완화와 관련된 요인을 분석하는 것이다. 이를 위해 총 5회에 걸쳐 지각된 스트레스(PSS-K), 영역별 스트레스(GARS), 외상후 스트레스 증상(IES-R) 및 우울감(BDI-II)의 변화를 시간 경과에 따라 분석하고, 캠프 후 6개월 시점의 스트레스에 영향을 미치는 요인을 조사하였다. 연구결과 스트레스 수준은 캠프 참여 전보다 낮아져 캠프 후 6개월까지 지속되었으나, 우울감은 캠프 직후에만 감소를 보였다. 캠프 참여 전 직장 스트레스가 높고 질병 스트레스가 낮을수록 캠프 프로그램을 통한 스트레스 완화 효과가 큰 것으로 나타났다. Background: This study aims to test the effectiveness of a camp program and to analyze the factors related to stress relief. To this end, the present study conducted prospective research for six months on the change of stress, depression, and the level of post-traumatic stress among the firefighters who participated in the camp program. Methods: The perceived stress (PSS-K), stress by the different portion (GARS), post-traumatic stress symptoms (IES-R) and depression (BDI-II) were evaluated at five sessions over the span of six months, and the change of each measure was analyzed. Those five sessions were before the camp, right after the camp and a month, three months and six months after the camp. Moreover, this study assessed characteristics of sociodemographic, firefighting task and mental health that are related to the level of stress at six months after the camp. Results: Compared with before the camp, the level of depression was significantly lower right after the camp. However, the level did not have significant difference after a month period. At one month after the camp, the level of stress was significantly lower than before the camp, and was maintained after six months. The predictive factors of the degree of stress relief after the camp were high job stress and low disease stress. Conclusions: This study has found that the stress relief from the camp continued until six months after the camp, and the stress-relieving effect through the camp was substantial for those with higher job stress and lower disease stress.
Linker: 공장 신속 재구성과 자율 운용을 위한 액티브 드라이버 Wrapper

In the era of Industry 4.0, manufacturing systems require essential capabilities of rapid-reconfiguration and autonomous operations. Many studies have been conducted to generate flexible plans and optimize task sequences at the shop floor system-level. However, little attention have paid on how to connect these task plans to the actual execution of field devices. Therefore, this paper proposes the concept and architecture of active driver wrapper (called linker) for improvised and interactive task execution. The linker architecture includes the definition for digital representation of devices and hardware abstraction to facilitate us to rapidly change the logical and physical configurations of manufacturing systems. In addition, each linker can proactively respond to the faulty situations of devices via peripheral intelligence. Four case studies were conducted to evaluate the potentials of the proposed architecture.

The cytologic diagnosis of the follicular variant of papillary thyroid carcinoma (FVPTC) has become one of the common causes of false negative diagnoses when performing fine needle aspiration cytology (FNAC) of the thyroid gland. We retrospectively reviewed all the aspirates for which a diagnosis of FVPTC had been made based on the surgically excised specimens, regardless of the cytologic diagnosis. 145 FNACs was performed in 135 patients. The cytologic diagnoses were categorized as 2 unsatisfactory specimens (1.4%), 16 benign (11.0%), 49 atypical (33.8%) and 78 malignant lesions (53.8%). The tumor cells consistently showed significant nuclear overlapping, irregular nuclei and fine chromatin in all cases; however, nuclear grooves and inclusions were scarce. Galectin-3 immunostaining was performed on the cell blocks of 65 cases and this was positive for 45 cases (69.2%). The results of our study demonstrate that the determination of minimal cytologic criteria is needed to raise the sensitivity of detecting FVPTC by FNAC, and galectin-3 immunostaining is useful to make decisions on the surgical treatment of cytologically atypical thyroid nodules.

Invasive micropapillary carcinoma (IMPC) of the breast is recently described rare variant of invasive ductal carcinoma. This variant has a distinctive histological features and aggressive biological behavior. We reviewed the cytologic features of eight cases of IMPC. The cytologic smears showed moderate to high cellularity and the tumor tissue was composed of atypical, angulated, cohesive clusters of neoplastic cells with a papillary to tubuloalveolar architecture, and a morular growth pattern without fibrovascular cores was seen on the histopathology. IMPC of the breast has distinctive cytologic features and it is important to make an early diagnosis via fine needle aspiration cytology due to this tumor's aggressive behavior.
