A Study of the Content Validity of Reading Comprehension Tests in NMET II
Zhen-Jie Liu,Ming-Hao Jin 대한언어학회 2018 언어학 Vol.26 No.4
Liu, Zhen-Jie & Jin, Ming-Hao. (2018). A study of the content validity of reading comprehension tests in NMET II. The Linguistic Association of Korea Journal, 26(4), 103-124. Based on Bachman and Palmer’s (1996) framework of task characteristics, this paper aims to compare the reading comprehension tests of the 2013-2017 National Matriculation English Test II (NMET II) with the requirements of the New Curriculum Standards and Testing Syllabus, in particular, concerning the content validity of the tests in terms of the characteristics of input and expected responses. The implications of this study are discussed for test designers, teachers, and students. The results show that reading comprehension tests from 2013 to 2017 basically meet the requirements of the New Curriculum Standard and Testing Syllabus and have a high content validity. In terms of the characteristics of input, the length, reading speed, and readability of comprehension passages are appropriate for students; however, the distribution of topics and genres in each year is uneven. In terms of the characteristics of expected responses, the wordings of questions and the design of question items are reasonable. However, the response type is mainly restricted to selected response questions (multiple-choice), and the measure of reading skills coverage is unbalanced.
HYPER 빔창주위의 열유동 해석에 의한 안전성 평가에 관한 연구

A spent fuel problem has prevented the nuclear power from claiming to be a completely clean energy source. The nuclear transmutation technology to incinerate the long lived radioactive nuclides and produce energy during the incineration process is believed to be one or the best solutions. HYPER(Hybrid Power Extraction Reactor)is the accelerator driven transmutation system which is being developed by KAERI(Korea Atomic Energy Research Institute). Some major feature of HYPER have been developed and employed. On-power fueling concepts are employed to keep system power constant with minimum variation of accelerator power. A hollow cylinder-type metal fuel is designed for the on-line refueling concept. Lead-bismuth(Pb-Bi) is adopted as a coolant and Spallation target material. One of the issues related to the HYPER target system is the thermal and mechanical loads imposed on the Pb-Bi and the beam window. FLUENT is used for thermal-hydraulic calculation, and finally stress calculation is performed by ANSYS. A beam condition such as current is varied. The initial velocity of Pb-Bi is also varied.

Single and 4 weeks oral administration of New wonbangwoohwangchungsimwon (NSCH) which was used l-muscone as substitutive material of musk, to beagle dogs of both sexes were performed to investigate both acute and subacute toxicity. Beagle dogs (3 males and 3 females) in acute experiments were administered orally with sinlge dose of 2,000 ㎎/㎏ and groups of 9 male and 9 female beagle dogs in subacute experiments were given daily different dosage of NSCH, 160 ㎎/㎏/day (low dosage group), 400 ㎎/㎏/day (middle dosage group), 1,000 ㎎/㎏/day (high dosage group) once a day for 4 weeks by oral route according to the Established Regulation of Korea Food and Drug Administration (1996. 4. 16). LD_50 value for beagle dogs was more than 2,000 ㎎/㎏ per oral for both male and females. In animals administered with NSCH, there were neither dead animals nor significant changes of body weights. In addition, no differences were found between control and treated groups in clinical sign, urinalysis, eye examination, hematology, serum chemistry, organ weight and other fingings. No histological lesions were observed in both control and treatment groups. Above data strongly suggset that NSCH in beagle dogs is considered to be safe.

IBM Zigbee Positioning Method for Smart Home Applications
Ming-Hui Jin,Chung-Jung Fu,Chih-Hao Yu,Hung-Ren Lai,Ming-Whei Feng 보안공학연구지원센터 2008 International Journal of Smart Home Vol.2 No.2
This paper presents a smart home system prototype which employs an indoor positioning system called the III Beacon Match (I3BM) positioning method to intelligently trigger the appropriately services for the home members. To overcome the ninja problem in the I3BM method, the signal filtering, adjustment and smooth procedures are proposed. The proposed system prototype employs the Zigbee module to implement the prototypes of the components for the I3BM positioning method, and the prototypes had passed the ZigBee Compliant Platform (ZCP) certification test. The proposed system prototype which intelligently controls the air condition and light system for smart home applications is also verifying in our demo room and in the smart house in National Taiwan University.
