  • This research is an investigation of difficulties encountered by authors of 5th and 6th grade science textbooks. The aim is to assist authors in creating more easily understandable textbooks in the future. In-depth interviews were conducted with 6 teachers who have previously taken part in the development of 5th and 6th grade texts. The responses given during these interviews were analyzed using open, axial, and selective coding as suggested by Strauss and Corbin (1998). The results are as follows: In open coding, related concepts were extracted and classified into 15 main categories and 46 sub-categories. In axial coding, the main categories were arranged into causal conditions, main phenomenon, context, intervening conditions, action and interactional strategies, and consequences wherein they were consistently related to each other based on Grounded theory. Finally, in selective coding, core categories were instilled whereby the texts being developed were categorized into conservative, progressive, and innovative to allow for easier interpretation. This was done to improve the overall quality of Science textbooks.

  • This study presents the alternative evaluation technique for the high-rise building structural system. The alternative evaluation of the structural system is performed in three steps, that is, preliminary evaluation, main evaluation and detailed evaluation. The evaluation categories are composed of structural performance, economic feasibility and term of work. Each categories are composed of detailed items to evaluate of its own. In preliminary evaluation, qualitative evaluation based on experimental knowledge is performed. In main and detailed evaluations, quantitative evaluations based on numeric data are performed. The weighted-sum method is applied to integrate the evaluated results of each items and its importance. The applicability of the proposed method was verified by applying it to the practical buildings and simulate the procedures.

  • This study examined 'traditional' and 'modern' food use in Korean adults. Using a 24 hour recall method, trained interviewers assessed dietary intakes of 240 subjects aged 20's to 50's living in Seoul. Depending on the cultural characteristics of foods, 495 different kinds of foods eaten by the subjects were classified into 6 (Korean, Western, Eastern, modified Korean, modofied Western, modified Eeatern) types. The foods were also divided into 3 ('main dish', 'side dish', 'others') categories. Based on these categories, the dietary intakes of the subjects were analyzed in terms of proportionate frequencies of individual food items. The most frequenctly eaten food was the Korean food (67.68%), followed by the Western (22.61%), modified Eatern (2.31%), modified Western (1.65%), and modified Korean (1.36%) foods. Regarding the main dish category, the Korean food received the highest proportion due to the Korean's frequent intake of rice. Korean style foods were the most frequenctly consumed side dish (43.97% of total food consumption). In particular, kimchi consisted of 27.4% of the foods consumed as a side dish. In the 'others' category, Western style foods obtained the highest proportion owing to coffee consumption. The results of the study indicates some methodological problems and suggests a need for further studies.

  • Human development is the important role of education. There were thinkers of China emphasized the importance of education. These are divided into two general point of view. One theory is that as the representative of Mencius, Xuncius. Environment and education will be acquired this means that there is a crucial human development. $S{\grave{o}}ng$, $M{\acute{i}}ng$ dynasty came to the training began to do research for a decisive action. The other is to represent the viewpoint of Dongzhongshu, $H{\acute{a}}nyu$. According to their education was not to transcend the inherent limitations. Educator of ancient China have had a perspective that humanity can change. Humans show the progress theory emphasizes the potential of toughness as compared to the effect of the training point of view was divided into three classes emphasize the birth. Debate and the search for the humanity of the ancient educator had left us a valuable ideological material. Their perspective on a variety of personality is judged that there are many still take part in educational as well as the value of exploring far today.

  • In this study, the axiomatic design(AD) method is applied to construct the hierarchical structure of evaluation criteria and the AHP method is used to calculate the weights of criteria in order to develop the proposal evaluation index for the overseas weapon system purchasing projects. The common evaluation items as main categories are selected through the review of evaluation criteria from the previous works and projects, relevant regulations and defense policy, and the design matrix using fuzzy concept is established and evaluated by the expert group in each design phase to determine the independency, that is the satisfaction of decoupled or uncoupled design, for each criteria in the same hierarchy when they are derived from the main categories. The establishment of decoupled or uncoupled design matrix provides mutually exclusiveness of how small number of DPs can be accounted for FRs within the same hierarchy. The proposal evaluation index developed in this study will be used as a general proposal evaluation index for the overseas weapon system purchasing projects which there are no systematically established evaluation tools.

  • Purpose: This study analyzed research trends related to childhood and adolescent cancer survivors (CACS) using word co-occurrence network analysis on studies registered in the Korean Citation Index (KCI). Methods: This word co-occurrence network analysis study explored major research trends by constructing a network based on relationships between keywords (semantic morphemes) in the abstracts of published articles. Research articles published in the KCI over the past 10 years were collected using the Biblio Data Collector tool included in the NetMiner Program (version 4), using "cancer survivors", "adolescent", and "child" as the main search terms. After pre-processing, analyses were conducted on centrality (degree and eigenvector), cohesion (community), and topic modeling. Results: For centrality, the top 10 keywords included "treatment", "factor", "intervention", "group", "radiotherapy", "health", "risk", "measurement", "outcome", and "quality of life". In terms of cohesion and topic analysis, three categories were identified as the major research trends: "treatment and complications", "adaptation and support needs", and "management and quality of life". Conclusion: The keywords from the three main categories reflected interdisciplinary identification. Many studies on adaptation and support needs were identified in our analysis of nursing literature. Further research on managing and evaluating the quality of life among CACS must also be conducted.

  • Highway Rest Areas are envisioned to provide an accessible space for rest and parking for travelers, especially those driving a long distance. In addition, modern highway Rest Areas provide many amenities to highway users, including wifi service, picnic tables, litter barrels, running water, public telephones, and sometimes even free coffee. Various studies were conducted in the domain of Rest Area facility design and their operating costs in different states; however, limited studies were conducted on the maintenance costs of these facilities. Therefore, this study's main objective is to compute the annual maintenance cost of Rest Areas in the state of Nevada. This study also analyzes the main cost categories of the maintenance works. The raw cost data of Nevada Rest Area maintenance from 1990 to 2012 were collected from the Nevada Department of Transportation (NDOT). Results show that the maintenance cost fluctuated over the study period; the maintenance cost decreased from 1991 to 2004 and then increased until 2012. The primary cost categories of maintenance work are labor, equipment, and material costs. Among these, labor cost was the largest category with 56 percent of the total maintenance cost, followed by equipment cost and material cost. The findings of this study may help NDOT and other transportation agencies plan their budget for future Rest Area maintenance activities.
