This study arms to examine the effeciveness of teacher's feedback on students' journal writing in English Sixty middle school students participated in this research and were given a journal writing task each week The students were divided into two experimental groups One group was given meaning-based feedback, and the other was given form-based feedback from the teacher The T-unit analysis and sentence combining analysis were used to investigate how much the syntactic maturity of each group was enhanced The results of this study are as follows 1) the teacher's feedback on English journal writing was found to be effective for the improvement of the Korean students' writing ability, and 2) there was no significant difference of effectiveness according to the feedback type on the improvement of students' English writing abilities

정부는 국내 미세먼지의 주요 원인 중 하나인 대형화물차의 연료를 경유에서 액화천연가스(LNG) 등의 친환경 연료로 전환하는 정책을 추진하고 있다. 부족한 충전 인프라의 문제점을 해결하고, LNG 연료의 초기 보급을 원활하게 하기 위해 규제자유특구를 통한 이동식충전소 개발과 실증이 진행되고 있다. 본 연구에서는 실증용 이동식충전소의 개발에 앞서 안전한 설계를 위해 정량적 위험성평가 프로그램을 활용하여 주요설비(저장, 충전)에 대한 피해영향범위를 산출하였으며, 가상 시나리오에 대한 개인적/사회적 위험도를 예측하여 위험성 분석을 실시하였다. 위험도 분석 결과, 이동식충전소 실증시설의 위험성은 가용한 범위 내에 있는 것으로 나타났다. The government is converting the fuel for trucks, one of the causes of PM in Korea, form diesel to LNG. Mobile LNG station are being developed to solve the problems of insufficient charging infrastructure and facilitate the spread of LNG fuel. In this study, QRA was used th calculate the CA of the facility for a secure design prior to the development of the mobile LNG station and to predict the individual/societal risk the scenario. As a result, the danger of mobile LNG station was in ALARP.

The purposes of this study were to investigate the relationship between anthropometric data of foot and other body sizes. to categorize the foot shape of elementary school boys and to find out determinant factors related the foot that enable us to deduce the foot shape and size for the design of more comfortable shoes. Subjects of this study were 249 elementary school boys of age ranged from 6 to 11 residing Seoul and lncheon area. Anthropometric sizes were measured with the direct measurement method using Martin scales and the indirect measurement method using digital photos. Pearson's correlation, factor analysis. cluster analysis. analysis of variance, post-hoc test, and cross tabs were performed for statistical analysis of the data by SPSS program. From the investigation on the relationship between foot-related items and body items, most items of foot measure were significantly related to body size items. However, angle of the foot did not related to other body sizes although other height items and mass items of the foot did have relationships with other body sizes. Results of ANOVA indicated there were significant differences in foot-related items except for items of foot angle and all body anthropometric items by subjects' age. This implicates big toe angle, little toe angle and foot ratio factors are required in sizing shoes besides foot length. On the basis of cluster analysis using factor scores. three different foot shapes were categorized. Type 1 was large and wide foot, Type 2 was small and narrow foot with large toe angle. and Type 3 was medium foot with no deformity on big toe. These three groups show significant differences in almost all measurement items. However, Rorher index and foot angle didn't show any significant differences among groups. This implicates the foot shape can be a determinant of shoe size.
