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.

The purpose of this research was to examine variables contributing to the father's role performance. The study has been designed to measure the quantitative(i.e. amount of involvement) and the qualitative(i.e. depth of affection/care) values in their modes of child-rearing practices by taking a clouter look at the father's views on their careers and on offspring. Subjects were 516 fathers of school-age children. Analyzing the factors that determine the quantitative and qualitative aspects of child-rearing practices by the fathers, the sense of fulfillment/value in life is the decisive factor behind the affection(i.e. qualitative) in the child-rearing practices. The resets indicated that the father's perceptions on their careers and on their children constitute the critical factors behind the qualitative and quantitative aspects of child-rearing practices, albeit holding such factors as the parents'working hour or as mothers with outside jobs under control.

As many organizations have adopted and implemented ERP systems, concerns about ERP performance also have increased. Former researches studied the ERP implementation of general large or medium size enterprises but there are not enough studies on ERP systems of a specific industry domain. In this paper, we introduce a case study on ERP adoption methodology of global leading company 'D' in shipbuilding and marine engineering industry. We examined ERP implementation background, method and scope and evaluated ERP performance in perspective of both quantitative and qualitative approaches. Quantitative research usually examines ERP performance based on financial statements and qualitative study typically examines organization change or improvement. As a result, ERP implementation in shipbuilding and marine industry can improve quantitative aspects such as cost, human resource and organization performance. As qualitative analysis, business process and tools can be unified and management transparency can be improved by ERP implementation. The result of this paper will be useful guideline for organizations which are considering ERP systems.

The various risk assessment methodologies have been introduced in the railway industries. The risk assessment suggested by CENELEC are described with two ways; quantitative and qualitative methods. However, in the industry application level, the quantitative method is hard to apply for a project because of somehow complicated or few statistical figures which was driven from the on-site and the qualitative method is too subject to have the confidence of its results fully. In this paper, the state-of-the-art methods which were suggested in Europe recently are introduced and compared to existing quantitative and qualitative methods. Furthermore, the application measures of railway projects are investigated.

This study examined two current learning models for covariational reasoning(Carlson et al.(2002), Thompson, & Carlson(2017)), applied the models to teaching two $9^{th}$ grade students, and analyzed the results according to the types of graphs(a quantitative graph or qualitative graph). Results showed that the model of Thompson and Carlson(2017) was more useful than that of Carlson et al.(2002) in figuring out the students' levels in their quantitative graphing activities. Applying Carlson et al.(2002)'s model made it possible to classify levels of the students in their qualitative graphs. The results of this study suggest that not only quantitative understanding but also qualitative understanding is important in investigating students' covariational reasoning levels. The model of Thompson and Carlson(2017) reveals more various aspects in exploring students' levels of quantitative understanding, and the model of Carlson et al.(2002) revealing more of qualitative understanding.

This study measures and compares the performance of research and development (R&D) programs in government-funded research institutes (GRIs) in terms of qualitative and quantitative approaches to find out strategic insights for improving performance evaluation policy. In particular, we adopt the evaluation results from the real data of K institute in 2015 for a qualitative evaluation and the results of data envelopment analysis (DEA) for a quantitative evaluation. Comparative analysis of the R&D performance of 14 programs finds that the difference between the evaluation results of qualitative and quantitative approaches is significant. From this finding, we suggest several strategic directions to complement two approaches each other.

This paper is a qualitative and quantitative study. The main purpose of the paper is to diagnose what makes English communication difficult at the Korean EFL adult level. In order to obtain data, this study employed interviews and a questionnaire. We identified thirty three factors blocking pathways to oral communication. Qualitative analysis repeatedly revealed patterns such as lack of grammar, lack of vocabulary, lack of background knowledge, and peer pressure, but quantitative analysis yielded somewhat different results: lack of colloquial expressions, lack of vocabulary, lack of various topics, problems in the educational system, difficulty in using existing knowledge, and lack of grammar. Findings which were common to both qualitative and quantitative analyses suggest that lack of linguistic knowledge and lack of background knowledge are major barriers learners encounter in communication. On the basis of the results, suggestions are made for overcoming these barriers.

The purpose of this study is to carry out the quantitative and qualitative analysis of an urban park in the landscape ecological view and to provide the important basic data in the urban development process. The results of this study are as follows. First, in the case of disposition distance analysis in quantitative plans, very necessary regions of the children park are turned out to be 24 sites, of the neighboring park are turned out to be 30 sites, and walking park are turned out to be 22 sites. Second, in the case of undevelopment neighborhood park analysis, priority orders are Daebong Park, Suseong Park Third, in the case of area, shape, and isolation in qualitative plans, interior area of Bummul park is larger than that of Chimsan park and isolation of Bummul park higher than that of Chimmsan.

This study performed qualitative and quantitative risk assessment of equipment for evaluating the protocol of hydrogen refueling stations and suggested measures to improve safety. Hazard and operability study was performed for qualitative risk assessment, and Hy-KoRAM was used for quantitative risk assessment. Through a qualitative risk assessment, additional ventilation devices were installed, simultaneous venting of the storage container was prohibited, and the number of repeated refilling of the evaluation equipment was identified to manage the number of fillings of the container. Through quantitative risk assessment, the area around the device was set as a restricted area when evaluating the station, and measures were suggested to reduce the frequency of accidents.

The purpose of this paper was to analyze the distribution ratio of citation in researches in food service and found the relationship of study. The result was as follows. First there were remarkably quantitative researches than qualitative researches. Second, the citation ratio of social studies was high according to frequency-analysis. Third, citation frequency of publication was the highest in the pre-study that included scientific papers, newspapers, art and science contest announcement data and so on. Fourth, there was much citation ratio of domestic literature than foreign literature.
