The purpose of this study is to analyse the eighth grade students' performance of open investigations for two kinds of tasks: the qualitative one which involves the descriptive approach through observation, and the quantitative one which involves the quantitative data processing through control of variables. Researcher's observation, interview data as well as students' investigation reports, self-evaluations were analysed. The difficulties of qualitative open investigation lie in detecting and dealing with unexpected observations, of which the acceptance and interpretation were influenced by preconceptions. On the other hand, managing several variables, making reliable and valid measures, and quantitative data processing constituted main difficulties of quantitative open investigation. Some students could recognize the deficiencies of their methods and findings in qualitative one, but few in quantitative one. These results suggest the teaching point for each task of open investigations.

Most elderly victims of senile dementia in Korea are cared for at home. This creates hardship for their families. Recent research suggests that the physical environment can affect the treatment of dementia. In light of these findings, a prudent approach to the design of the housing environment of family with dementia sufferers is advisable. This study aims to determine the design factors that need to be considered for the housing environment of dementia, particularly for those suffering from Alzheimer's or Cerebrovascular dementia. For this study, and in-depth qualitative investigation method was employed. Principal caregivers were interviewed using various investigative tools, including objective measures, structured and non-structured questionnaires. The investigation results suggest that the need for housing environment improvement varies with the severity and type of dementia. The housing needs in this study, is expected to promote a focus on improved design management for the environment and housing of dementia and their families. The results also suggest the establishment of a welfare policy for senile dementia victims and their families.

This study developed the learning ability-based smart education program. The effectiveness of the developed materials was investigated using the quantitative-qualitative mixed method, and the process and results of the investigation are as follows. The quantitative investigation was conducted using the non-equivalent pretest-posttest design, in which the smart education method was applied to the experimental group, while the conventional education method was applied to the control group to analyze students' creative problem-solving potential, task concentration, and the variables required for the learning activity. The results showed significantly higher performance in the experimental group over the control group. Regarding data collection in the qualitative investigation, an analysis of the class from the instructor and class consultation logs from the class analyst were collected; the comments on the experience of each class period were collected from students. The results of the analysis of the data suggest that the perception of smart education improved for the instructor, class analyst, and learners as the course progressed.

In this study, a qualitative evaluation of the morphological changes in the seabed surrounding Jinwoo-Island due to the construction of the new Busan port were determined through a numerical simulation. Various scenarios for the discharge of the Nakdong river estuary dam and construction stage of the new Busan port were established and utilized for an indirect and qualitative investigation through simulation using the numerical model implemented in this study. It was concluded through a qualitative study that the morphological changes in the seabed surrounding Jinwoo-Island were typical estuary seabed changes due to the discharge of the Nakdong river estuary dam and waves from the open sea. The effects from the construction of the new Busan port were relatively small.

The intent of this study is to propose future planning guidelines and directions of the mixed-use buildings in the residential land development district in country-side cities, based on the concept that the neighborhood facilities are to be strategically laid out in a convenient location and planned in a proper manner for a healthy, safe, friendly and new neighborhood environment. For this purpose, seventeen mixed-use buildings which had been built in Shin-Eum housing development district in Gimcheon from 1995 until 2004 were chosen and investigated in terms of architectural characteristics in that process with surveying and analyzing those. The scope of investigation on case studies was that site size would be below 400 square meters, total area below 1500 square meters, and the number of stories below five stories high on the ground. Method of investigation on those was through field investigation, field photographs, recordings and drawings on those. Investigative contents have been divided and analyzed into the quantitative and qualitative factors in urban and architectural dimension. From results of quantitative investigations, five planning guidelines or directions could be obtained. From results of qualitative investigations, five planning guidelines or directions could be obtained. The criteria will be applied to new architectural developments of the neighborhood facilities linked with the small shops.

Purpose: This qualitative study was to understand the awareness of epidemiological investigation tasks for nurses who were in charge of coronavirus disease 2019 (COVID-19) epidemiological investigations. Methods: Before data collection, written consent was obtained from 13 participants, and the data were then collected from September 1 to December 31, 2021. Individual interviews were conducted and recorded by video interview using Zoom, and data were transcribed verbatim. Four themes were derived by using the qualitative thematic analysis method. Results: The participants perceived that epidemiological investigations were burdensome but that the field work was important, and that expertise and collaboration were required. The participants started work without preparation due to the explosive increase in the number of confirmed COVID-19 cases, and they recognized work conflicts, unstable employment, and exhaustion as obstacles to their work performance. On the other hand, the participants took pride in contributing to the national epidemiological investigation and control and felt a sense of responsibility as nursing professionals. Finally, participants mentioned that the training of infectious disease practitioner was important for work improvement. Conclusion: Further research is needed on the development of standardized manuals for the training of nursing personnel as infectious disease specialists through the job analysis of epidemiological investigators.

This study was a qualitative investigation into the food security and food variety among the rural elderly. For the qualitative data collection, nineteen elderly people who lived in Yangpyeong-gun were interviewed individually. Food security and variety was evaluated based on accessibility and affordability. The participants seemed to have difficulty preparing their own meals and eating with their families or others. The frequency of vegetable intake was found to be high, as vegetables were available through cultivation. However, in terms of diversity, the intake of meat and milk, which are sources of protein and calcium, was found to be significantly low. This has to do with very poor physical accessibility. A lack of nutrition education was identified as the biggest reason for not following dietary therapy despite having a pre-existing disease condition. Therefore, for the elderly in Yangpyeong-gun, it is suggested that a basic nutrition policy for food supply that can increase their actual intake is more essential than education on cooking and nutrients. Moreover, periodic nutrition education or a regular counseling system for dietary therapy through local public health centers may help improve the health of the elderly.
