Purpose: Topic modeling is a text mining technique that extracts concepts from textual data and uncovers semantic structures and potential knowledge frameworks within context. This study aimed to identify major keywords and network structures for each major topic to discern research trends in women's health nursing published in the Korean Journal of Women Health Nursing (KJWHN) using text network analysis and topic modeling. Methods: The study targeted papers with English abstracts among 373 articles published in KJWHN from January 2011 to December 2021. Text network analysis and topic modeling were employed, and the analysis consisted of five steps: (1) data collection, (2) word extraction and refinement, (3) extraction of keywords and creation of networks, (4) network centrality analysis and key topic selection, and (5) topic modeling. Results: Six major keywords, each corresponding to a topic, were extracted through topic modeling analysis: "gynecologic neoplasms," "menopausal health," "health behavior," "infertility," "women's health in transition," and "nursing education for women." Conclusion: The latent topics from the target studies primarily focused on the health of women across all age groups. Research related to women's health is evolving with changing times and warrants further progress in the future. Future research on women's health nursing should explore various topics that reflect changes in social trends, and research methods should be diversified accordingly.

This study was conducted to identify whether there is a significant difference in the developmental stages of the evolution concept depending on the major and the country. For this study, college students (both biology major and non-biology major) in Korea and the United States answered evolution concept assessment developed by Ha (2007). The data were analyzed based on the method of developed by Ha (2016). As a result of this study, Cronbach alpha for internal consistency reliability and MNSQ indices for item response fitness of the ordered multiple choice method providing 0 to 4 point scores to creationism, teleology, intentionality, use/disuse, and natural selection respectively, satisfied the benchmark. The level of Korean college students' evolution concepts was located in use/disuse and the level of USA college students' evolution concepts was located in teleology. No interaction effect was found between the difference of conceptual progressions of evolution concept by major and country and evolution contexts (human, animal, and plant). There was a significant relationship between developmental stages of evolution concept and their religiosity. Based on the results of this study, we discuss developmental characteristics of evolutionary concepts.

Objectives : The purpose of this study was to examine the influential factors for the choice of dental institutions among adult office workers who were one of major medical consumer groups, the relationship between their health promotion lifestyle and their choice of dental institutions, ways of boosting the efficiency of hospital management and differences in differentiation strategies among dental institutions. Methods : The subjects in this study were 160 office workers who were aged 20 and over and worked in Seoul, North Jeolla Province and South Jeolla Province. They were selected by convenience sampling, and a survey was conducted from February 1 to July 20, 2011. The answer sheets from 149 respondents were analyzed by the statistical package SPSS WIN 12.0 except for 11 incomplete ones. Results : As for the selection factors of dental institutions by general characteristics, they attached a statistically and significantly different importance to convenience according to gender(p<0.05), to reliability, facilities and cleanness according to age(p<0.05), to reliability and convenience according to academic credential(p<0.05) and to facilities and cleanness according to academic credential(p<0.01). Concerning the links between the form of using dental institutions and the selection factors of dental institutions, they gave a statistically and significantly different weight to reliability according to that(p<0.05). Convenience(p<0.001) was the primary selection factor of dental institutions among those who scored higher in health promotion lifestyle. Conclusions : Given the above-mentioned findings, it seemed that the regular implementation of oral health plans geared toward workers and the development of educational programs are required to promote the oral health of workers. But this study examined the workers in several regions only, and the findings might not be generalizable.

New product development (NPD) is defined as the transformation of a market opportunity and a set of assumptions about product technology into a product available for sale. Managers charged with project selection decisions in the NPD process, such as go/no-go choices and specific resource allocation decisions, are faced with a complicated problem. Therefore, the ability to develop new successful products has identifies as a major determinant in sustaining a firm's competitive advantage. The purpose of this study is to develop a new evaluation model for NPD project selection in the high -tech industry using support vector machines (SYM). The evaluation model is developed through two phases. In the first phase, binary (go/no-go) classification prediction model, i.e. SVM for high-tech NPD project selection is developed. In the second phase. using the predicted output value of SVM, feasibility grade is calculated for the final NPD project decision making. In this study, the feasibility grades are also divided as three level grades. We assume that the frequency of NPD project cases is symmetrically determined according to the feasibility grades and misclassification errors are partially minimized by the multiple grades. However, the horizon of grade level can be changed by firms' NPD strategy. Our proposed feasibility grade method is more reasonable in NPD decision problems by considering particularly risk factor of NPD in viewpoints of future NPD success probability. In our empirical study using Korean NPD cases, the SVM significantly outperformed ANN and logistic regression as benchmark models in hit ratio. And the feasibility grades generated from the predicted output value of SVM showed that they can offer a useful guideline for NPD project selection.

The purpose of this study was to examine and analyze motivation of entrance into the college, knowledge prior to the entrance, satisfaction with their major, and a sense of employment after graduation among students majoring in dental hygiene at some colleges and subdivide them by grades for comparative analysis to determine the progress of changes in general characteristics, department satisfaction, and a sense of employment among students majoring in dental hygiene for the recent three years and provide basic data for improving dental hygienic education. Questionnaires were distributed to 520 students majoring in dental hygiene at some college in South Chungcheong, South Jeolla, and North Jeolla Provinces, followed by explanation of the purport of the research and the content of the questionnaire; after completion, 513 copies were used for analysis with exception of 7 copies with insincere responses. The analysis of the data examined resulted in the following conclusions: First, Changes in Department Satisfaction among Students Majoring in Dental Hygiene As for motivation of entrance into a college, less and less students chose the department of dental hygiene through recommendation by parents or seniors while more and more students chose their major due to easy employment. Less and less students obtained information on the department from a college application guidebook while more and more students obtained it through Internet. There was also a gradual increase in prior knowledge about the department and in satisfaction with their major. More and more students had no will to change their course. Second, Changes in a Sense of Employment among Students Majoring in Dental Hygiene There was a gradual decrease in the number of students who would follow friends' or their own decision in selecting workplace but an increase in the number of those who would follow their professors' opinion. There was a gradual increase in the number of students who wanted to be employed in workplace with good social perception; many students wanted to be employed in a personal dental clinic, a general hospital, or a public health center; and more and more students also wanted to be employed in a school dental health center or to become a government official or an educator.

This study analyzed the correlations between variables like characteristics related to admission, academic achievement, obtainment of a radiological technology license. A majority of participants were from Daegu and academic high schools. Many participants were accepted by general admission selection, and their reason to apply to Daegu Health College was high graduate employment. Their selection for the academic program was made by their parents and themselves. Those who took the same course twice held 35.1%, and those who got an academic warning took 8.5%. The degree of participants' academic achievement showed somewhat low, and they had difficulty in taking their major courses. The average grade for admission was lower in a following selection order: college graduates, general, special, and rural areas. The admission selections and taking science courses in high school showed little significant correlations with obtainment of a radiological technology license. However, the obtainment of the license had significant correlations with retaking the same course, getting an academic warning, and the degree of academic achievement. The results also revealed that the obtainment of the license had little significant correlations with a part-time job experience, having a boy/girlfriend, and student club participation, but it had significant correlations with accommodations and study club participation. In conclusion, it is important to point out that radiological technology graduates' obtainment of a license is closely related with the degree of their academic achievement and their college life.

This study was conducted to designing conserved regions of molecules for virus-derived resistance to transgenic Phlaenopsis orchids to protect against two major orchid viruses, Cymbidum mosaic virus (CymMV) and Odontoglossum ringspot virus (ORSV). Infected leaf samples of Phalaenopsis were randomly screened by the RT-PCR with specific primers to both of viruses. RT-PCR products of the viruses were cloned and their nucleotide sequences were determined. Multiple alignments of coat protein (CP) genes of the viruses revealed that over the 88 ％ and 94 ％ identities with CymMV and ORSV, respectively, were observed. These data can be useful for selection of highly conserved regions of CP gene of the viruses for transgenic orchid experiments.

This study purports to investigate the determinants of individual personnel rating of the employees at a university hospital in Seoul, Korea. The sample used in this study consisted of 63 nurses, 41 para-medical staff (Clinical Pathologist, and Radiologist), and 67 administrative staff. Independent variables of the study included the achievement level of the selection test (English, major subject, and interview), post-entrance development factors (education and training, career development, supervisory support, co-worker support, and organizational support), and demographic characteristics. Data for the achievement level of the entrance exam and years for the first promotion were collected from the administrative records of the study hospital, while data for the post-entrance development factors were collected from the survey with self-administered questionnaires using 5-point Likert Scale during June 10-25, 2003. Collected data were analyzed using hierarchical multiple regression. The results of the study showed that achievement level of the interview and English exam at the selection test, education and training, organizational support, and supervisory support while working at the hospital, and length of duration (below 8 years) and educational background (4-year college graduates) among demographic variables had significant positive effects on the personnel rating. The results of the study imply that hospital administrators should make an effort to improve the validity of the selection test, and to motivate the employees to receive more education and training.

Promulgation of the medical practice rule without specific definition in Medical Law has brought about many constitutional issues. The major issue is that the law has the government punish unlicensed medical practice without defining what it is. Instead, the law chooses a license-centered structure of criminal punishment for medical malpractice, saying "no one can practice medicine without the government-approved license." This regulation violates the rule of "void for vagueness" based on the principle of "nulla poena nullum crimen sine lege." Judicial interpretation should be required for a citizen to understand the Medical Law provision intuitively. In addition, the law infringes upon the freedom of occupation of the unlicensed and the licensed who wish to extend his or her practice area for "holistic medicine." The central issue of the law is that it was established under no ground of professionalism even though medical practice has been understood professional. The government has centrally controlled the medical field for its needs. Lastly, the current law violates the right of medical selection of the consumers of medicine. Because patients have the right of health and life, they have to hold the latitude of selection for medical treatments. Especially, they should have an opportunity for considering the Complementary and Alternative Medicine if they want. But under the current rules, this medicine is not permitted. To correct those problems, a new provision for the definition of medical practice should be adopted at once.
