For the development of qualitative and quantitative PCR methods of genetically modified (GM) pepper developed in Korea, a capsanthin-capsorubin synthase (CCS) gene was used as the endogenous reference gene. The primer pair ccs-F/R amplifying the pepper endogenous gene gave rise to an amplicon of 102 bp. No amplified product was observed when DNA samples from 16 different plants were used as templates. The construct-specific primer pairs amplifying the junction region of the bar gene and Ti7 introduced in GM pepper gave rise to an amplicon of 182 bp. Quantitative PCR assay was performed using a TaqMan probe and a standard plasmid as a reference molecule, which contained both an endogenous and event-specific sequence. For the validation of this method, the test samples containing 0.1, 1, 3, 5, and 10% GM pepper were quantified.

The culture filtrate of Lentinula edodes shows potent antimicrobial activity against the plant pathogenic bacteria Ralstonia solanacearum. Bioassay-guided fractionation was conducted using Diaion HP-20 column chromatography, and the insoluble active compound was not adsorbed on the resin. Further fractionation by high-performance liquid chromatography (HPLC) suggested that the active compounds were organic acids. Nine organic acids were detected in the culture filtrate of L. edodes; oxalic acid was the major component and exhibited antibacterial activity against nine different phytopathogenic bacteria. Quantitative analysis by HPLC revealed that the content of oxalic acid was higher in the water extract from spent mushroom substrate than in liquid culture. This suggests that the water extract of spent L. edodes substrate is an eco-friendly control agent for plant diseases.

Modern society is increasingly demanding in many areas of big data processing technology to collect, aggregate, and analyze large amounts of data over the Internet and SNS. A typical application is to evaluate the reputation of a company or college. To measure and quantify a reputation, fair and precise data and efficient data processing are very important. For this purpose, a quantitative quotient was obtained using public data, a qualitative quotient was obtained through sentiment analysis using news articles, and a complex college reputation quotient was calculated. In this paper, a complex college reputation quotient was calculated based on the quantitative index, reflecting the sentimental reputation, and based on the proposed mixed university system. In this paper, the Complex College Reputation System(CCRS) was proposed, which produced the Complex College Reputation Quotient with an objective quantitative quotient and qualitative quotient reflecting the sentimental reputation to measure the college reputation.

Recently, in the shipping companies have been employing prudently in order to prevent from sea accidents occurred by human factors. Also the students of merchant marine universities are choosing prudently the shipping companies when taking a job. But many qualitative and quantitative factors are considered in decision making for the employment. FSM(Fuzzy Structural Modeling) has been widely used in modeling the system composed of such qualitative and quantitative factor. In this paper, a case study is discussed for the analysis of the consciousness of the employment of shipping companies using FSM. Also this paper proposed the planes for educating and recruitment guiding the student in maritime university.

This qualitative study investigates how qualitative research methods are applied into educational journals, especially focusing on research articles in the field of mathematics education. Since the mid 90s, there has been growing interest in qualitative research in Korea. As a result, qualitative research methods are becoming one of the main research methods in education, quite different from before the mid 90s that quantitative research methods themselves alone were undispute d research methods. However, such change in research methods also lead to a matter of concern, the rigor and quality of qualitative research. In order to identify how qualitative research methods are applied, this study carefully selects an d analyzes 5 article that used qualitative methods and were published by Education of Primary School Mathematics Journal in 2012. Several leading scholars' ideas and theories of qualitative research are used in the analytical process, with careful attention paid to every detailed element of 5 selected articles. In sum, this study concludes with practical implications for qualitative researchers and discusses future directions for improving qualitative research practice.

Purpose: This study was done to develop a internalized stigma reducing program based on cognitive-behavioral therapy and appropriate for patients with schizophrenia and to evaluate its effectiveness. Methods: The study design was a mixed method research. Qualitative study, 13 patients with schizophrenia who had experience in overcoming stigma were purposively chosen for interviews and data were analyzed using Giorgi method. Quantitative study, 64 patients with schizophrenia (experimental group =32, control group =32) were recruited. The cognitive-behavioral therapy-based program for reducing internalized stigma in patients with schizophrenia was provided for 8 weeks (12 sessions). Data were collected from June. 20, 2013 to Feb. 14, 2014. Quantitative data were analyzed using ${\chi}^2-test$, t-test, repeated measures ANOVA with the SPSS program. Results: Qualitative results, from the experience of coping with stigma in patients with schizophrenia seventeen themes and five themes-clusters were drawn up. Quantitative results showed that internalized stigma, self-esteem, mental health recovery and quality of life were significantly better in the experimental group compared to the control group. Conclusion: Study findings indicate that this program for reducing internalized stigma in patients with schizophrenia is effective and can be recommended as a rehabilitation program intervention to help patients with schizophrenia to cope with internalized stigma.

This study focused on the public library evaluation indicators in 2022 to examine the changes and improvement recommendations. In addition, this study analyzed the results of changes in the proportion between the qualitative and quantitative evaluation. Eventually, there was a comparison between the current and previous evaluation outcomes. Furthermore, we examined the effectiveness of the current evaluation groupings of libraries. Then, we tried to discover new quantitative evaluation variables that affected the evaluation score calculation. Finally, we proposed a method for estimating variables through standardization and individualization, as well as a scheme to encourage the voluntary participation of public libraries in the evaluation.

Cognition and control of grinding trouble occurring during the grinding process are classified into a quantitative knowledge which depends on experimental data and qualitative knowledge which relies on skilful engineers. Grinding operations include a large number of functional parameters, since there are several ways of coping with grinding trouble. One is the qualitative method which depends on empirical knowledge utilizing the skilful experts from the workship, the other is the quantitative method which utilizes the experimental data obtained by a sensor. But, they are all difficult to accomplish from the grinding trouble-shooting system. The reason is that grinding troubles are now easily controlled in the quantitative method, and therefore, trouble-shooting has mainly relied on the knowledge of skilful engineers. Thus, there is an important issue of how a grinding trouble-shooting system can be designed and what knowledge is utilized among the large amount of grinding trouble information. In this paper, basic strategy to develop the grinding database of rule-based model, which is strongly depended upon experience and intuition , is described.
