본 연구는 성인 문해력 조사연구의 국제 동향을 분석하여 우리나라 성인 문해력 조사 도구 개발 및 문해교육 정책의 시사점을 얻기 위한 것이다. 이를 위하여, 국제 표준화 조사도구와 별도로 독자적인 성인 문해력 조사 도구를 개발하여 활용하고 있는 영국, 프랑스, 독일의 성인 문해력 조사 방법을 비교 분석 하였다. 분석 결과, 세 국가는 성인 문해교육 정책의 연계성 속에서 생활문해 또는 기능문해의 관점에서 문해의 의미를 정의 내리고 있었으며, 읽기와 쓰기를 중심으로 수리력과 정보 활용 능력도 측정하고 있었다. 문해력 수준의 판정은 각 국가별 상황을 고려하여 다양하게 이루어지고 있었으며 조사의 정책 연계성과 효율성을 강조하는 SQC모델을 채택하고 있었다. 이런 분석 결과를 통해 우리나라 성인 문해력 조사를 실시함에 있어 성인 문해교육 정책의 실행과 조사 주체의 일원화, 일상생활을 반영한 조사도구의 개발, 수준별 문해력 측정, 조사도구의 모듈화, 조사의 경제성과 활용성의 확보 등의 시사점을 얻을 수 있었다.

During last two decades the transportation system has developed into very intelligent system with GIS, GPS and ITS. The practical transportation management system provides real time response module to manage the customer's order. We have surveyed research papers on the real time vehicle routing problem in last two decades to figure out the dynamic vehicle routing problem. The papers are classified by basic routing algorithms and by managing the dynamic events which are the order management, the routing re-optimization, the routing post-optimization and the waiting strategy.

Three dimensional (3D) non-linear finite element analysis of offshore pipeline is investigated in this work with the help of general purpose software Abaqus. The general algorithm for the finite element approach is introduced. The 3D seabed mesh, limited to a corridor along the pipeline, is extracted from survey data via Fledermous software. Moreover soil bearing capacity and coefficient of frictions, obtained from the field survey report, and are introduced into the finite element model through the interaction module. For a case of study, a 32inch pipeline with API 5L X65 material grade subjected to high pressure and high temperature loading is investigated in more details.

The purpose of this study was to assess risk factors associated with food insecurity in the Korean elderly aged over 65 years using data from the Korea National Health & Nutrition Examination Survey 2013 (KNHANES VI). A total of 1,200 subjects were analyzed among the participants of the KNHANES 2013 by using SPSS statistics complex samples (ver. 21.0). Food insecurity was measured by using the modified US Household Food Security/Hunger Survey Module. Thirteen percent of subjects lived in food insecure households. There were differences in the prevalence of food insecurity according to sex, educational level, income level, and household structure. Mean age of the food insecurity group was significantly higher than that of the food security group. The results of logistic regression analysis showed that food insecurity was significantly associated with alcohol intake (OR: 1.82), prevalence of melancholy (OR: 2.07) and suicidal thoughts (OR: 2.67), and intake deficiency of energy (OR: 1.60), calcium (OR: 1.97), iron (OR: 1.97), potassium (OR: 1.96), riboflavin (OR: 1.76), and niacin (OR: 1.64), while not with smoking, physical activity, chronic diseases including obesity, anemia, diabetes, and osteoarthritis, and deficiency of protein, vitamin A, thiamin and vitamin C. These findings suggest that food insecurity is strongly related to mental health and certain nutrient intakes. Prospective research is needed to establish the effects of food insecurity on chronic diseases.

일반적인 지질조사에서는 많은 양의 지질구조 측정을 위하여 수동 컴퍼스를 사용하고 있다. 암반사면의 건축과 터널의 증가로 인해 좀 더 정밀한 지질조사 요구 때문에 휴대용 다용도 디지털 컴퍼스가 필요하다. 이 시스템은 마이크로 컨트롤러로서 Intel PXA 255 임베디드 보드가 사용되어 만들어졌으며, 기울기 센서, 방위각 센서, 그리고 위성항법장치로 구성되어져 있다. 우리가 개발한 시스템으로 측정되어진 경사 값과 주향 값, 그리고 위치 값은 PDA나 노트북으로 전송되어 지질구조 분석을 위하여 쓰여질 것이다. 본 논문에서 개발된 값싸며 성능이 향상된 디지털 컴퍼스는 광대한 지질 조사에 있어서 많은 비용과 시간을 절약하는 역할을 하리라 기대된다.

BACKGROUND/OBJECTIVES: The purpose of this study was to investigate the association between socioeconomic status and chewing discomfort and identify the role of food insecurity in the association's causal pathway in a representative sample of Korean elders. MATERIALS/METHODS: We conducted cross-sectional analyses of the Korea National Health and Nutrition Examination Survey (2013-2015) data for elders aged ≥ 65 years. Socioeconomic status indicators used included household income and education level. Chewing discomfort was assessed according to the self-reported presence of chewing problems. Food security was surveyed using a questionnaire based on the US Household Food Security Survey Module. RESULTS: The odds ratios of chewing discomfort in the 1st and 2nd income quartiles were 1.55 (95% confidence interval [CI], 1.15-2.10) and 1.40 (95% CI, 1.03-1.90), respectively, compared to participants in the highest income quartile. Participants with the lowest education level were 1.89 (95% CI, 1.30-2.75) times more likely to have chewing discomfort than those without chewing discomfort. After including food security in the final model, the logistic coefficients were attenuated in the income and education quartiles. CONCLUSIONS: Low socioeconomic status was associated with chewing discomfort. In addition, the results confirm that food insecurity can mediate the association between socioeconomic inequalities and chewing discomfort among the elderly.

The purpose of this study was to analyze the planning characteristics and it's application of container architecture as case study. Field survey was used to analyze the spatial planning characteristics in terms of development outline, appearance, exterior, floor plan and interior of eight famous cases in Berlin, Hamburg, Hannover, Amsterdam and Paris of Europe. The results of this study were as follows; Firstly, good examples of container architectures such as student housing, social service center, temporary medical facility and cruise terminal in Europe suggested the potential of domestic applicability in various purposes and development. Secondly, various types of freight container, building container and module frame system should be developed with their reprocessing environment. Thirdly, it is necessary for us to develop ISO type(20~40ft) container and standard plan with interior and storage design reflecting demands of residents. Finally, the use of container module will be an environmental-friendly alternative for its modularity and reusability, so it should be used as it is without severe deformation. The development of environmental friendly energy sources such as hydro and solar power is necessary for domestic container architecture as well. The container design should include the use of high quality of exterior finishing materials and the plan of aesthetical color planning to make the building a local landmark.

This paper is a series of study for the development of rural elementary school facilities model applying to the regional characteristics. Therefore, main theme of this paper is to pile up and analysis of elementary school facilities data in Po Cheon through a series of actual survey and interview with teachers. The results are summarized as follows ; First of all, in case of Po Cheon, it needs to study for urban model type as well as rural elementary school facilities model type. Second, extension type of buildings has separated as three types-zigzag extension type, vertical & horizontal extension type, separate building type. But another characteristics, such as type of site plan, type of corridor and module of classroom unit, outdoor space and elevation design, are monotonous. Third. the results of this analysis show that it is desirable to locate houses for teachers within boundaries. Finally, the future paper needs to be studying more various module of classroom unit, extension type, space program, type of floor plan and site plan.
