  • Drought is defined by differently for the several scientific and technical fields such as hydrological drought, agricultural drought, meteorological drought, climatological drought, atmospheric drought. A lot of drought indices have been developed to quantify drought severity levels. However these drought indices might be expressed differently as the drought conditions for specific period because the drought severity level is using different types of data on each condition. It is necessary for development of quantative drought representation methods by drought index application. In this research, the reaction to the historical droughts is analyzed after estimation of PDSI, SPI and MSWSI(Modified Surface Water Supply Index) in south korean territory. Lastly the drought representation methods were examiner combining the drought indices by drought indices. The arithmetic mean drought indices that include PDSI, SPI, in yearly basis from 1971 to 2001 and MSWSI in yearly basis from 1974 to 2001 were estimated through the whole nation. The applicability of drought indices are examined based on the observed drought data for national and regional droughts. The result shows that PDSI, SPI(3), SPI(6), and MSWSI have proven to be sensitive enough to the historical drought. The correlation analysis of each drought index was conducted whether they could show the long and short term drought equally. The analysis of how appropriately represent for the historical drought was used for determining for the combined drought index. Consequently, PDSI, SPI(3), SPI(6), and MSWSI have been appeared as suitable indices for the development of quantitative drought representation methods. For the decision of weight on combining PDSI, SPI(3), SPI(6), and MSWSI, drought map was made for eighteen alternative to decide weight. The results showed that PDSI(20%), SPI(3)(60%), SPI(6)(10%), and MSWSI(10%) have been the most well matched weights. Using selected weights of each drought indices and by reconstructing the national mean drought severity on yearly basis, the fact that the year of historical drought is in accordance with the verified one for drought representation. In short, the acquired technique using combined drought index can be used for useful and believable quantitative method of drought analysis.

  • Purpose: The purpose of this study was to analysis the manuscripts rejected for publication in the Journal of Korean Academy of Nursing Administration during the last three years six months (2012~2015 Jun). Methods: Seventy eight rejected manuscripts were analyzed focusing on manuscripts characteristics, such as rejection rates, year of submission, occupation of first author and corresponding author, number of authors, funding, thesis or dissertation, article type, study participants, number of reviews prior to rejection, and 3rd reviewer. Also reviewers' quantitative evaluation scores and subjective comments were analyzed. Reviewers' subjective comments were analyzed using content analysis methodology. Results: The mean rate for manuscript rejection was 28.9% and for quantitative research, qualitative research, and review papers the quantitative evaluation scores were $2.54{\pm}0.70$, $2.39{\pm}0.69$, and $2.39{\pm}0.69$ out of 5 points, respectively. The most frequent subjective comment on rejected manuscripts was 'lack of rationale for research need'. Conclusion: In this study the characteristics and the reasons for rejecting manuscripts were identified. These findings can be used in developing effective strategies for researchers, reviewers and editors to improve the quality of research and research reviews of nursing administration research.

  • In recent decades, the research field of entrepreneurship phenomenon has significantly increased in both quantity and sophistication. In Vietnam, paradoxically, while creating a new business venture has become a tendency, the interest in studying entrepreneurs seems not to be thoroughly investigated. This research aims to evaluate the factors that affect the entrepreneurial intention of information technology (IT) students in Vietnam. The authors make use of mixed methods including both quantitative research method and qualitative research method. The qualitative research method is employed to identify meanings, confirmations, adjustments, and compliments for concept-measurement variables in the conceptual model. Quantitative research is conducted from a sample of 424 IT senior students across many universities in Vietnam. Questionnaires have been sent to students to evaluate the measurement scale and appropriateness of the research model. Results from multiple regression highlighted five independent variables affecting the dependent variable, the entrepreneurial intention, in a descending order as following: entrepreneurial educational environment, personal characteristics, perception of feasibility, entrepreneurial supports, and financial accessibility. In addition, this research has proved that the variable attitudes towards entrepreneurship partially mediated among the interrelationship of the aforementioned variables. From this research, the authors make some recommendations to enhance entrepreneurial intentions of IT students in Vietnam.

  • Experimental examinations for evaluating fracutres were conducted by using transparent replicas of a single fracture in order to obtain the fracture data to contribute to the methodlogy on how to improve the definitaion of representative parameter values used for a parallel plate fracture model. Quantitative aperture distribution and quantitative tracer concentration data at each point in time were obtained by measuring the attenuation of transmitted light through the fracture in high spatial resolution. the representative aperture values evaluated from the multiple different measurement methods, such as arithmetic mean of aperture distribution measured by the optical method, transport aperture evaluated from the tracer test, and average aperture evaluated from the fracture void volume measurement converged to a unique value that indicates the accuracy of this experimental study. The aperture data was employed for verifying the numerical simulation under the assuption of Local Cubic Law and showed that the calculated flow rate through the fracture is 10%-100% larger than hydraulic test results. The quantitative tracer concentration data is also very valuable for validating existing numerical code for advection dispersion transport in-plane heterogeneous fractures.

  • This research was conducted in order to examine previous studies on paternal parenting methods involving adolescent children in terms of their academic field, research period, method and subjects, and family variables. A total of 104 research publications from the period between 2003 and 2022 were investigated, with 99 quantitative research (43 theses and 56 academic journals) and five qualitative data sources. The analysis results show that the topic of fathers with adolescent children was the most studied in the field of education, and it rapidly increased from 2011 to 2014 and then rapidly decreased from 2019. The main subject of the studies was middle-school students, while most of the studies adopted a quantitative approach, with a minimal number of qualitative studies. Parenting studies were concentrated on father variables and several such studies were found to be related to positive resources such as self-esteem and self-efficacy as variables of adolescent children related to fathers' parenting. The results of these studies provide meaningful implications for future research on the fathers of adolescent children and can be used as basic data for developing detailed education and programs.

  • Background: Few studies have explored the knowledge and attitudes of adolescents toward cancer prevention and treatment. This lack of research and its potential utility in the development of new educational initiatives and screening methods, or the reconstruction of existing ones, provided the impetus for this study. The primary research aim was to assess secondary school student knowledge of cancer and determine whether or not they possessed basic knowledge of cancer symptoms, risk factors, and treatments and to determine the relationship between cancer knowledge and key demographic factors. Materials and Methods: The Management and Science University conducted a cross-sectional study analyzing responses through cross-tabulation with the socio-demographic data collected. Results: The findings of our quantitative analysis suggest that Malaysian youth generally possess a moderate knowledge about cancer. Quantitative analyses found that socioeconomic inequalities and bias in education present as important factors contributing to cancer awareness, prevention, and treatment among Malaysian adolescents. Conclusions: The findings indicate that Malaysian youth generally possess a moderate knowledge about cancer but the current deficiencies in initiatives directed to cancer awareness continue to hinder the improvement in prevention of cancer among Malaysian adolescents.
