The purpose of this study was to develop appropriate spelling writing instruction based on phonological awareness activities that teachers can use in parallel with textbooks to teach 3rd graders in elementary school. Eighteen 3rd grade students(9 males and 9 females) participated in the activities and 6 students were selected to investigate the characteristics of the development in their spelling writing skills. The results of the study showed that the instruction had positive effects on the development of students’ spelling writing skills. The study also showed that the instruction increased the confidence and interest of 6 students in English spelling writing. In addition, the students had a very high preference for word making activities using alphabet chips. These results drew the following conclusions. First, phonological awareness based spelling writing activities in the early reading stages should be conducted continuously in order for the students to better decipher, accurately read, and write new words. Secondly, the national curriculum based textbooks should present phonological awareness instructional materials. Finally, it is suggested that teacher training programs should be provided to support effective spelling writing instruction for the elementary English class.

1인 가구의 급격한 증가는 전통적 가족해체와 시장구조의 변화를 초래하고 있으며, 1인 가구의 양극화 현상과 맞물려 주거공간의 공유를 포함하는 새로운 주거유형을 요구하고 있다. 이에, 1인 가구의 주거정책, 주거요구, 주거유형의 3가지 키워드를 중심으로 주거에 관한 탐색적 연구를 수행하였다. 총 36개의 학습자원(학술논문, 학위논문, 전문자료)을 대상으로 체계적인 내용분석을 수행하였다. 내용분석은 일반화가 어려운 연구주제 또는 분야에서 객관적인 연구동향 파악에 적합한 연구방법으로 유용하다. 또한, 설문조사를 통해 내용분석 결과에 대한 후속적인 검증작업이 진행되었다. 그 결과로 1인 가구 주거에 관한 정책적, 사용자 특성별, 건축 유형별 1인 가구를 위한 주거요구가 도출되었다. 특히, 5개의 1인 가구 주거유형이 심층적으로 분석되었으며, 그 결과로 우리나라 상황에 맞는 1인 가구 주거유형 개발을 위한 시사점이 탐색 및 제시되었다. 향후, 주거정책, 주거요구, 주거유형에 관한 보다 세분화된 연구수행이 필요할 것이다. The rapid increase in single-person households resulted in disintegrating traditional families and changing housing market structure. This study was performed to examine three keywords or research subjects such as housing policies, housing needs and housing types for the particular households. A total of 36 learning resources(academic theses, degree theses, professional reports) were explored for contents analysis, which has been known to be the most useful method to figure out a generalized tendency for such subjects. The results were proved via on-line based survey questionnaires. As a result, overall housing needs were analyzed based on political, user, architectural characteristics of single-person households. Particularly, 5 types of housing were deeply examined in terms of spaces, which then lead to creating a set of guidelines for future korean single-person households. A more specific effort should be contributed to purify housing policy, housing needs and housing types for that particular population.

Focusing on the Cases Applied to Korean Brand-name Apartments In 1960s, economical growth and introduction of western-type cultures led to a boom of apartment construction. After internationalizationin 1980s through Olympic games in 1988, Korean culture has attracted attention and individual life quality has been improved. Since 1990s, changes in personal life style has affected the housing culture and the construction companies started moving from quantitative supply to developing their own differential characteristics. Differentiation scheme triggered by construction companies since mid-1990s mainly focused on various ideas for space deployment. Space plans include such things as a private ground, a kitchen in the south, etc., while interior plans include to provide selection of the Korean-type, natural or casual one. ‘Korean-type’ apartment is one of such theme of the brand-named apartment. Interests on ‘Tradition’ canbe broken down into a social trend and media trend. Firstly, the former includes the designation of Bukchon as a reserving area, one of the governmental ‘Hanok Survival Program’, and traditional building promotion scheme on the basis of construction policy plans. Secondly, the latter covers the interests which attract through the media showing oriental cosmetics, Korean culture export via Hallyu, popularity of Korean dramas, etc. Thus, it seems worth studying on the apartments with traditional factors. And also, this study aims to setup the concept and trends of Korean-type apartments through the interior expression on the Korean-factor space developed by brand-name apartments so that it could correct such false knowledge out of misunderstood concept of traditional space which results from simple decoration or structure type not accompanying Korean emotion or spirit rendered by some misleading media.

In order to evaluate the precision and accuracy using LA-ICP/MS, thirty major and trace elements were analyzed with 3 USGS SRMs. And we investigated correlation between metal concentrations in five species tree-ring and ambient air heavy metal pollution history in ambient air. Total thirty major and trace elements in three USGS basalt glass reference materials, BIR-1G, BCR-2G and BHVO-2G were determined using LA-ICP/MS. Calibration was performed using NIST glass SRM 610, 612 and 614 in conjunction with internal standardization using Ca. Relative standard deviation(RSD) of determinations was below 10% for most elements in all glasses under investigation. All the USGS SRMs showed negative correlations between RSD and concentrations for elements with logarithmic correlation coefficients ranging from -0.867 to -0.790. Furthermore, these values were similar results obtained in NIST glass SRM 610, 612, 614. In natural sample analysis, 7 heavy metals in 5 tree species(Platanus occidentalis, Salix koreensis, Chamaecyparis obtusa, Pinus densiflora, Ginkgo biloba) were determined using LA-ICP/MS, and calibration was performed using cellulose - matrix matched standards with ¹³C nomalization. Four tree ring series showed that the Pb and Fe accumulation rates were higher between '92~'99 except for Ginkgo sp., but other elements(Cr, Mn, Cd, Zn, Sr) varied depending on species, which was caused by the physiological process of element uptake and radial mobility. Pb and Cd concentrations in tree ring of Pinus sp. have correlated with the ambient air heavy metal monitoring data which showed the correlation coefficients of 0.879 and 0.579, respectively. Pb and Cd concentrations in tree-ring of Salix sp. and Platanus sp. showed positive correlation with coefficients of 0.671 and 0.825, respectively. Therefore, our results suggested that Pb and Cd concentrations of Pinus sp. can be interpreted in terms of ambient air heavy metal pollution history.

Nitrogen loading from domestic, agricultural and industrial sources can lead to excessive growth of macrophytes or phytoplankton in aquatic environment. Many studies have used stable isotope ratios to identify anthropogenic nitrogen in aquatic systems as a useful method for studying nitrogen cycle. In this study to evaluate the precision and accuracy of denitrification bacteria method (Pseudomonas chlororaphis ssp. aureofaciens(ATCC® 13985)), three reference (I AEA-NO-3 (Potassium nitrate KNO₃), USGS34(Potassium nitrate KNO₃), USGS35(Sodium nitrate KNO3)) were analyzed 5 times repeatedly. Measured the δ¹⁵N-NO₃ and δ¹⁸O-NO₃ values of IAEA-NO-3, USGS34 and USGS35 were δ¹⁵N:4.7±0.1‰ δ¹⁸O:25.6±0.5‰, δ¹⁵N:-1.8±0.1‰ δ¹⁸O:-27.8±0.4‰, and δ¹⁵N:2.7±0.2‰ δ¹⁸O:57.5±0.7‰, respectively, which are within recommended values of analytical uncertainties. Also, we investigated isotope values of potential nitrogen source (soil, synthetic fertilizer and organic-animal manures) and temporal patterns of δ¹⁵N-NO3 and δ¹⁸O-NO₃ values in groundwater samples during from May to December. δ¹⁵N-NO3 and δ¹⁸O-NO₃ values are enriched in December suggesting that organic-animal manures should be one of the main N sources in those areas. The current study clarifies the reliability of denitrification bacteria method and the usefulness of stable isotopic techniques to trace the anthropogenic nitrogen source in freshwater ecosystem.

The purpose of this study is to develop a cultural instruction model for primary English education based on digital literacy using digital textbooks. To accomplish the objective, this study examined the importance and direction of cultural education in primary English education and analyzed the components of intercultural competence and digital literacy. On the basis of the literature review of language-cultural integrated education instruction models and digital literacy education instruction models, this study developed a five-step instruction model called MACER (Motivate-Activate-Communicate-Evaluate-Reflect) to integrate language-cultural instruction and digital literacy into English education, which is expected to be effectively applicable in the primary cultural education field. To enhance the validity of the MACER model, a survey was conducted. Then, this study modified and refined the MACER model. Finally, this study introduced steps that teachers can follow to show how the MACER instruction model could work in planning language-cultural instruction in primary English education.
