  • An abundance of information is available regarding soil horizons and their characteristics. Several methods can be used to gather and analyze this information. Through the use of qualitative analysis in the field, and laboratory and statistical analysis, a soil can be compared and analyzed with a great deal of scrutiny. Four soil pits were excavated in Citrus County Florida and samples were collected from each master horizon. Through the use of qualitative and quantitative analysis these samples were compared and analyzed in order to identify unique, as well as homogeneous features. It was determined that the soil profile designated Old Pit was different than other profiles because of landscape position and variations in parent material. Landscape position (ie. slope position) also influenced the genesis and evolution of the soils in the other three profiles(Profile 1, 2 and 3).

  • This study aims to analyze the effect of urban ecosystem restoration projects by evaluating the short-term restoration performance of the project sites, from both qualitative and quantitative evaluations. In this study, for the qualitative evaluation, we derived the evaluation frame from previous studies and literature. For the quantitative evaluation, the changes in ecological connectivity after the restoration project were described using landscape permeability and network analysis. In addition, changes in habitat quality after the restoration project were evaluated by using InVEST Habitat Quality Model. These evaluations were applied to the three natural madang (ecological restoration) projects and two ecosystem conservation cooperation projects. As a result, three categories, 10 indicators, and 13 sub-indicators were derived from literature as the evaluation frame for this study. In the case of quantitative evaluation of restoration performance, habitat quality increased by 45% and ecological connectivity by 37% in natural-madang, and habitat quality by about 12% and ecological connectivity by about 19% in ecosystem conservation cooperation projects. This implies that the ecological restoration project can increase the ecological connectivity and the habitat quality of degraded sites even in a short period of time by improving the land-cover and land use. The results by applying the evaluation frame indicated that ecological and environmental factors and the ecological functions were improved by the restoration works, even though the magnitude of performances were diverse depending on the specific evaluation items, project type, and site characteristics. This study clarified that the success of ecological restoration project should be assessed by both of the short-term and long-term goals, which can be achieved by the maintenance and sustainable management, respectively.

  • Purpose: This study was aimed to classify the major subjects and theme and to analyze the data collection and analysis method in research papers published in the Korean Parent-Child Health Journal of the Academic Society of Parent-Child Health since 1998. Methods: A total 152 studies published from the first edition to volume 12, number 2 were reviewed using structured analysis criteria developed by researchers; research type, research design, research subjects, research theme, data collection and analysis method. Research theme was founded 4 nursing domains. Data collection and analysis method of papers were limited to quantitative and qualitative researches. Results: One hundred papers conducted quantitative research; 79.0% used survey design. Most of the data collection and analysis method in quantitative research were self-reported questionnaire (69.4%) and parametric statistics respectively. The research subjects of sixty three papers were parent with well or child. The common domain studies was human related concepts such as raring. Conclusion: The findings of this study suggest that published studies have been improved and diversified, however, detailed and clear evaluation tool that assess study process and method should be developed as a way to further improve the quality of published papers in the Korean Parent-Child Health Journal.

  • This study explores actual conditions and experiences on the rigor of social welfare qualitative researchers in Korea by using a qualitative inquiry. To examine the actual conditions on the rigor, this study analyzes 2,112 articles published in 8 Korean social work journals from 1979 to 2006. And to explores the experiences of social welfare qualitative researcher on the rigor, this study analyzes the experiences of qualitative research by using individual interviews and focus group interviews. The characteristics of social welfare qualitative research in Korea tend to enlarge according to the needs by doctoral candidates, coexist with post-positivism and constructivism. The analysis of both quantitative and qualitative results show that the rigor of social welfare qualitative research is very important to secure the validity and control the quality of qualitative research. Based on these results, this study introduced concrete tasks related to secure the rigor of social welfare qualitative research in Korea.

  • This paper executes positive analysis about the thesis of 100 volumes which were published for 2000-2006 years through 'Korean System Dynamics Journal', to grope and to see the academic developments of Korean System Dynamics. The summarized analysis results are same as follows. First, Korean System Dynamics researches appear that quantitative researches are much more than qualitative ones. Second, the researches that aimed to solve problem are relatively much more than theory-oriented ones. Third, System Dynamics researches in the department of social science are more abundant than that of science and engineering. Based on these results, for establishing of Korean System Dynamics identity, we will work hard to study qualitative researches, increase the research domains and elevate the academic statue of System Dynamics.

  • The quality of service on urban roadways have been evaluated mainly based on such quantitative measures as travel speed and delay. However, in addition to the quantitative aspects, drivers traveling on urban roadways are subject to be influenced by qualitative measures such as aesthetic aspects of the roadway and other drivers' violation of traffic laws. Based on this notion, this study attempts to identify roadway service quality indices, considering both qualitative and quantitative aspects and evaluate the quality of service using the modified Importance-Performance Analysis (IPA), a technique often applied in the field of marketing. The modified IPA is proposed in this study as a way to evaluate the service quality, reflecting the relative performance between study areas and performance indices. A case study is implemented over the Gangnam and Gangbuk areas in Seoul, resulting in identifying the items needed to be improved for each study area.

  • Importance of technology evaluation cannot be overemphasized to support the effective investment policy. Most of the technology evaluation relies on either quantitative analysis for the value or qualitative comparison due to some attribute. When qualitative comparison is made, typically not only individual attribute. but also overall score is evaluated by the committee of experts. In this paper, we consider the qualitative evaluation procedure used in a venture incubating center and validate if the relationship between the average score of individual attribute and the overall score is significant. Additionally, we identify if the initially evaluated scores are good indicators for the realized future value of technology. Structural equation modeling approach is used and we expect that our approach can make important contributions on improving the currently used technology evaluation method.

  • In recent years, shearogrpahy has significantly improved capabilities In the areas of unbend and separation detection in tires. Although shearography has many advantages fur qualitative evaluation, the technique remains the problem of quantitative analysis of inside defects, because shearography needs several effective factors including the amount of shearing, shearine direction and induced load, which exist as barrier for the quantitative analysis of inside defects. Since the factors are highly dependent on inspectors skill and also affect the in-situ workability. The factors were optimized and the size of cracks inside of pipeline and tire has been quantitatively determined.
