Comparisons of L2 Learners’ Written Performance by Two Types of Error Analysis

황은경 현대영어교육학회 2012 현대영어교육 Vol.13 No.4

This study compares the results of linguistic errors of Korean EFL college learners’ corpus with two types of error analysis. 86 female college students participated in the study, and wrote a narrative essay through the Criterion®. After their essays were rated by e-rater®, they were divided into three proficiency groups according to writing scores and then linguistic errors were classified, based on Ferris’ (2002) error classification. All linguistic errors were analyzed by two different frames such as conventional analysis (i.e., the number of each error type and its percentage) and T-unit analysis (i.e., the number of each error type was divided by T-unit). Through the comparison of two error analysis, morphological errors were the most frequent, followed by lexical errors across writing proficiency levels. Syntactic errors were the least frequent among these three main types of errors. The same results arose from two different error ratio measures, but error distribution across writing proficiency levels differed. In particular, error ratio measures with T-units yielded more accurate results when analyzing error distribution across writing proficiency levels. The findings suggest that error analysis through this new ratio measure presents more verifiable results than through conventional analysis.

Syntactic Complexity of Korean EFL Learners’ Argumentative Writing

황은경 현대영어교육학회 2013 현대영어교육 Vol.14 No.2

This study aimed to examine the level of syntactic complexity of Korean EFL college learners. A total of 319 writing samples were gathered and rated by the e-rater® engine,and were then divided into four L2 writing proficiency groups. Through the L2syntactic complexity analyzer 2.4 program, ten sub-measures of syntactic complexity were analyzed. This study found significant correlations between writing scores and syntactic complexity. In addition, all syntactic complexity measures indicated significant positive increasing linear trends as L2 writing proficiency increases, and showed significant group differences across four writing proficiency groups. The present study also suggests that mean length of T-units (MLT), clauses per sentence (C/S), and complex nominals per clause (CN/T) are the most reliable indicators to examine L2 syntactic complexity because they show clear delineation in L2developmental stages among the different levels of L2 writing proficiency. The findings of this study provide some useful pedagogical implications for teaching and assessing ESL/EFL writings of different language proficiency levels. It is hoped that the findings of this study add to the body of research on L2 writing, while also directing further research.

Induction of regeneration and maturation of the free-living gametophytes of Saccharina japonica was studied at four temperatures (5, 10, 15 and 20˚C), four levels of irradiance (5, 10, 20 and 40 μmol m-2 s-1) and three photoperiods (14 : 10, 12 : 12 and 10 : 14 h L : D). Female gametophyte fragments were maintained in active regeneration without reaching sexual maturity under conditions of 15˚C, 20 μmol m-2 s-1, 10 : 14 h (L : D), whereas the conditions for male gametophytes were slightly different at 15˚C, 5 μmol m-2 s-1, 14 : 10 h (L : D). The sexual maturation of female and male gametophytes took place under 5˚C, 20~40 μmol m-2 s-1, 10 : 14 h (L : D) and 15˚C, 40 μmol m-2 s-1, 10 : 14 h (L : D), respectively. These results provide basic information for controlling the regenerationand maturation of free-living gametophytes for strain improvement and cross breeding of S. japonica.

황은경,박근수,임석호,이승언,문수영 대한건축학회 2005 대한건축학회논문집 Vol.21 No.11

There are 16 government departments and 212 laws related the architectural regulations in Korea and improvement in life quality make them strengthening and subdivision. Since 1990, government strives to abolish various regulations, but most people consider laws related architecture as useless. In this study, we grasp the present regulation to divide and catch by adminstration and behavior in architecture. There are three-kind category about present regulations and they can be arranged by the 15-piece item. The three-kind category of regulation problems are that ; the contents which become a standard between construction regulations are different to each other, the laws related architecture and cooperation are inadequate and the contents which were reformed are not reflected directly at laws related architecture. So, in this study, we propose two kinds of improvement programme ; to revise the existing regulations and to make a new regulation.

이동약자를 고려한 건축물 피난규정 개선 방안에 관한 연구

황은경 한국화재소방학회 2009 한국화재소방학회논문지 Vol.23 No.6

최근 건축물의 대형화·고층화·고밀화·복합화 등으로 인해 건축물 내 재난사고가 발생할 경우 재실 자의 안전을 확보하기 위한 건축물 피난 설계가 매우 중요한 관건으로 이슈화되고 있다. 특히 장애인·노 인·임산부 등은 심신의 일시적 또는 영구적 장애로 인해 위급 대처 능력이 부족하기 때문에 건물내 화 재 발생시 가장 피해를 볼 수 있는 재해 약자라 할 수 있다. 그런데 우리나라의 경우 이동 편의성은 장 애인·노인·임산부 등의 편의증진보장에 관한 법률에 그리고 피난 안전성은 건축물 피난·방화구조 등 의 기준에 관한 규칙에 각각 이분화되어 규정되어 있다. 물론 각 개별법령에 의한 제정 목적은 상이하나 동일한 재실자를 대상으로 동일한 건축부위에 대한 설계기준이 상호연계가 부족하다면 건축설계 및 피난 설계자들에게 혼란을 야기할 수 있다. 따라서 본 연구에서는 장애인편의증진법과 건축물 피난규칙의 비교 분석을 통해 각 법령간의 상이점을 살펴보고 이에 대한 통합 기준을 제안하였다. Owing to increase of the large-scaled, high-raised and complexed building construction, the escape design of the building became very important issue to insure the safety of occupant. Specially, it is demanded to have building escape regulation considering for inconvenient movers such as disables elders pregnant women. However, building regulations for inconvenient movers are divided into “Regulation of Escape and Fire-prevention of Building” and “Act on the Promotion and Guarantee of Access for the Disabled, the Aged and Pregnant Women to Facilities and Information”. But, for the escape security of inconvenient movers, the connection of each regulation are necessary. So this study suggested the improvement direction of the building escape regulation considering inconvenient movers through the compared analysis on the “Regulation of Escape and Fire-prevention of Building” and “Act on the Promotion and Guarantee of Access for the Disabled, the Aged and Pregnant Women to Facilities and Information”.

Construction industry occupied very important position in national economy. For construction market activation, people want to be offered preferentially the construction environment which can do a construction act easy. However, there are 16 department and 210 laws related architecture in Korea and improvement in life quality make them strengthening and subdivision. Since 1990, government strives to abolish various regulations, but most people consider laws related architecture as useless. There are lots of problem among the law related architecture. Especially, there are many statutes which must be checked related to a building permit and much wastes time and money in review because of overlapping laws related architecture. In this study, we are going to raise several points between laws related architecture and to propose the construction regulation improvement.
