The aim of this study is to apprehend characteristics and demands of users about variation type in middle and high schools. It is analysed based on the questionnaire of teachers and students at work in five middle and high schools. The results showed that the variation type is quite helpful to teaching and learning activities in both teachers and students. However, it is shown that the students feel movement itself regard as a troublesome work, and dissatisfaction degree of the students is highly appeared to the existing facilities with the traffic line for each class. As shown in the results, introduction of variation type in teaching and learning activities in present facilities is not reasonable and alternative architectural plan must be necessarily proposed for rearrangement.

In this study, analysing the corresponding relation of a learning activities and a physical system by an alteration into the 7th curriculum, I would like to find the obstacles of facilities. Inspecting the above, this paper gets a technical data to build the facilities rearrangement model which is able to cope with the new curriculum. For this purpose, we analyse the hierarchy about space and the students' behavior on variation type in the standard school building, using the Analytic Hierarchy Process(AHP) to rearrange the rural middle and high school by the variation type. For the purpose of this study, the participants in this survey were the teachers from the five schools instructing the students on variation type with standard school building, the survey is about the gravity of physical facilities including a study space, an athletic space, a living space, a management space and a pathway. Added to this, to get the students' moving characteristics, we observe the second-year students's moving behavior in the special class room and general class room of the BS high school in recess.

Syntactic Categories in Early Child English: A Corpus Study of Article Production

( Kum-jeong Joo ),( Isaiah Wonho Yoo ),( Kitaek Kim ) 서울대학교 인지과학연구소 2020 Journal of Cognitive Science Vol.21 No.4

A topic of ongoing debate in regard to the acquisition of English articles is whether the articles very young children produce are abstract categories or limited scope formulae. This study investigates the issue by analyzing five English-speaking children’s corpus data, classified into four phases according to the number of article+noun combinations. The study has two main findings. First, the analysis found no sign of a U-shaped curve in the development of overt articles in obligatory contexts, a finding which indicates that the children did not pass through an initial stage of producing articles only as part of rote-learned formulae. Second, it was found that children produced predicate adjectives but no postverbal articles lacking nouns, a finding which constitutes evidence for the acquisition of articles. Taken together, the results provide positive evidence that English-speaking children’s early articles are an overt instantiation of an adult-like syntactic category.

Factors for Preferred Internal Orderings of Korean Noun Phrases

Kum-Jeong Joo 서울대학교 언어교육원 2015 語學硏究 Vol.51 No.2

This study explores what factors affect preferred internal orderings of Korean noun phrases (nps) that include demonstratives, numerals, adjectives, and nouns. I consider a syntactic account, a processing account, and a semantic compositionality account. I conducted an experiment in which native Korean-speaking adults completed an acceptability judgment task and an online self-paced reading task. The results of the acceptability judgment indicate a ranking in the naturalness of the structures. The most acceptable np is DEM+A+N+NUM, and the least acceptable is A+DEM+ NUM+N. The self-paced reading task found that the np with the highest acceptability, DEM+A+N+NUM, shows the fastest response times, while the np with the lowest acceptability, A+DEM+ NUM+N, shows the slowest response times. The results suggest that the preferred internal orderings of Korean nps are those in which processing is facilitated by two conditions: domain minimization and semantic compositionality

Acquisition of Word Order in the Adjective-Added Korean Classifier Phrases

( Kum-jeong Joo ) 서울대학교 인지과학연구소 2017 Journal of Cognitive Science Vol.18 No.1

This study explores the acquisition of internal orderings of adjective-added Korean classifier phrases. When a classifier phrase includes an adjective, two constraints rule out impossible orderings: adjectives occur before the noun they modify, and no modifying elements can intervene between the number and the classifier. An acceptability judgment experiment was conducted with native Korean-speaking adults and children to test their knowledge of the two constraints. The results indicate that, like adults, the children know the two constraints, disallowing impossible orderings. The results also show a ranking in the preference of the possible orderings. We suggest that semantic compositionality (i.e., A and N together) can account for the preferred internal orderings of Korean adjective-added classifier phrases.

The Acquisition of Abstract Syntactic Knowledge

Kum-Jeong Joo 한국언어학회 2018 언어 Vol.43 No.4

Two different approaches have been taken in an attempt to explain DPs in early child language: Some argue that children"s internal grammar is not different from that of adults and others insist that any determiner in early child language lacks functional categories or the features in adult language. This study investigates these assumptions with respect to one of DPs, the articles. In particular, it examines an article usage that has a bearing on this question, articles in formulae, in the data of twenty-one English-acquiring children below MLU 3.0. The main finding of the study is that the majority of the children"s utterances containing articles in the data cannot be considered formulaic. Although some previous research has found early article use to be limited to rote-learned sequences, this study concludes that articles in early English child language comprise an adult-like functional category.

A Processing-Based Account for the Preferred Ordering of the Korean Classifier Structures

( Kum Jeong Joo ),( Kitaek Kim ) 서울대학교 인지과학연구소 2016 Journal of Cognitive Science Vol.17 No.3

This study explores whether native Korean speakers have a preference between the two numeral classifier structures, N+NUM+CL and NUM+CLgen+N. According to Hawkins’s (2004) domain minimization account, the N+NUM+CL structure would be preferred over the NUM+CLge +N structure because the former considerably has a bigger IC-to-word ratio than the latter. To test this prediction, we conducted an experiment in which native Korean-speaking adults completed two acceptability judgment tasks, one written (n = 67) and one spoken (n = 46). The results of the two acceptability judgment tasks indicate that native Korean speakers prefer N+NUM+CL over NU +CLgen+N, compatible with the prediction of the domain minimization account.

Who is Caki?: Experimental studies regarding the person feature of the Korean reflexive caki

( Kum Jeong Joo ) 서강대학교 언어정보연구소 2015 언어와 정보 사회 Vol.26 No.-

The goal of this paper is to establish whether the Korean reflexive caki takes only the third person subject in practice, as the traditional account claims, or if it allows a first person antecedent (Oshima 2006; Kim and Yoon 2009). We thus empirically tested whether the first person subject in a biclausal sentence can be the antecedent of caki. Two experiments employing grammaticality judgment tasks were conducted with adult native Korean speakers. The results of the two experiments revealed that the grammaticality ratings differed according to the conditions, indicating that Korean speakers are sensitive to the person feature of caki. Notably, the participants did not accept a first person antecedent for caki, contrary to Oshima(2006) and Kim and Yoon(2009).

The electrical, morphological, and mechanical properties of poly carbonate (PC)/multi-walled carbon nan-otube (MWNT) composites were studied by electrical conductivity, electromagnetic interference shielding efficiency (EMI SE), scanning electron microscopy, and tensile strength measurements. In the electrical property analysis of the PC/MWNT composites, the percolation threshold of the PC/MWNT composites was observed between 1.5 and 2.5 wt% MWNT content. From the electrical conductivity and EMI SE studies, the theoretical values of the EMI SE were in good agreement with the experimental values of the EMI SE. From the morphology of the PC/MWNT composites, it was observed that MWNT is dispersed homogenously in the PC matrix. From the electrical conductivity and morphological studies, it was suggested that the percolation threshold of the PC/MWNT composites is related with the morphological results in that MWNT is apparently interconnected to form an electrical pathway. The mechanical properties of the PC/MWNT composites peaked at the MWNT content of 2.5 wt%.

PIXEL-BASED CORRECTION METHOD FOR GAFCHROMIC^®EBT FILM DOSIMETRY

Jeong, Hae-Sun,Han, Young-Yih,Kum, O-Yeon,Kim, Chan-Hyeong,Ju, Sang-Gyu,Shin, Jung-Suk,Kim, Jin-Sung,Park, Joo-Hwan Korean Nuclear Society 2010 Nuclear Engineering and Technology Vol.42 No.6

In this paper, a new approach using a pixel-based correction method was developed to fix the non-uniform responses of flat-bed type scanners used for radiochromic film dosimetry. In order to validate the method's performance, two cases were tested: the first consisted of simple dose distributions delivered by a single port; the second was a complicated dose distribution composed of multiple beams. In the case of the simple individual dose condition, ten different doses, from 8.3 cGy to 307.1 cGy, were measured, horizontal profiles were analyzed using the pixel-based correcton method and compared with results measured by an ionization chamber and results corrected using the existing correction method. A complicated inverse pyramid dose distribution was made by piling up four different field shapes, which were measured with GAFCHROMIC$^{(R)}$EBT film and compared with the Monte Carlo calculation; as well as the dose distribution corrected using a conventional method. The results showed that a pixel-based correction method reduced dose difference from the reference measurement down to 1% in the flat dose distribution region or 2 mm in a steep dose gradient region compared to the reference data, which were ionization chamber measurement data for simple cases and the MC computed data for the complicated case, with an exception for very low doses of less than about 10 cGy in the simple case. Therefore, the pixel-based scanner correction method is expected to enhance the accuracy of GAFCHROMIC$^{(R)}$EBT film dosimetry, which is a widely used tool for two-dimensional dosimetry.
