This study examined the trends in home economics education research across different curriculum periods and journals. A total of 374 papers related to the 2009, 2015, and 2022 revised curricula were selected and analyzed using network analysis from four journals. First, research trends were analyzed by curriculum period. Keyword frequency analysis revealed that articles on the 2009 and 2015 revised curricula primarily focused on analyzing the curriculum to develop textbooks or programs. In contrast, papers on the 2022 revised curriculum explored broader directions. Topic modeling results highlighted the prominent topics for each period: 'environmental education' in the 2009 revised curriculum, 'safety and health education' in the 2015 revised curriculum, and 'ecological transition' in the 2022 revised curriculum. Second, research trends were analyzed by journal. Keyword frequency analysis by journal exposed specific research tendencies. For example, in the Journal of Home Economics Research, 'perceptions of practical classes' and 'analysis of safety textbooks' were major topics for the 2009 revised curriculum, while 'teaching and learning plans for competence development' dominated research on the 2015 revised curriculum. This study demonstrates that the concepts and goals emphasized in curriculum revisions are reflected in the corresponding research.

This study investigates the change of level of psychosocial factors of decisional balance, processes of change, and self-efficacy after nutrition education on vegetable and fruit intake of children in pre-action stages. Forty-seven 5th grade elementary school children in Yeongi-Gun, Chungnam-Do were categorized into pre-action stages from a total of 71 children by four-stage questions, and then finally into two stages of precontemplation and contemplation & preparation. After 6 weeks nutrition education, recognition of both of pros and cons of vegetable intake were improved in the two groups of precontemplation and contemplation & preparation. In fruits intake, however, recognition of pros was not changed after nutrition education in either stage, but recognition of cons was improved only in the precontemplation stage. However, no difference in any psychosocial variables was found between precontemplation stage and contemplation & preparation stage. After the nutrition education, the score of consciousness raising of vegetable intake belonging to cognitive process of change increased in the subjects of the precontemplation stage, wheres the scores of dramatic relief, self-reevaluation, environment reevaluation and social liberation increased in the group of contemplation & preparation. In fruit intake, however, no change was found except in the environment reevaluation in the precontemplation group. The behavioral process of change of vegetable and fruit intake did not show any change in either group after nutrition education. Self-efficacy scores of vegetable intake of keeping the foods at hand, eating the recommended number of servings and making time to eat increased in the precontemplation group, while in the contemplation & preparation group, self efficacy scores of shopping for a variety of vegetables, instead of keeping the foods at hands, as well as the scores of the rest two items of eating the recommended number of servings and making time to eat increased after nutrition education. However, in case of fruits intake, no difference was shown in the precontemplation stage except an item of keeping the foods at hand. The results indicated that the stage of change was progressed in the pre-action stage after nutrition education and the scores of many psychosocial factors increased in both pre-action stages. It is suggested that the recognition of cons as well as the cognitive process of change and self-efficacy could be best used as indicators of the assessment of nutrition education program for vegetable intake.

Purpose - To improve and strengthen existing publication and research ethics, KODISA has identified and presented various cases which have violated publication and research ethics and principles in recent years. The editorial office of KODISA has been providing and continues to provide advice and feedback on publication ethics to researchers during peer review and editorial decision making process. Providing advice and feedback on publication ethics will ensure researchers to have an opportunity to correct their mistakes or make appropriate decisions and avoid any violations in research ethics. The purpose of this paper is to identify different cases of ethical violation in research and inform and educate researchers to avoid any violations in publication and research ethics. Furthermore, this article will demonstrate how KODISA journals identify and penalize ethical violations and strengthens its publication ethics and practices. Research design, data and methodology - This paper examines different types of ethical violation in publication and research ethics. The paper identifies and analyzes all ethical violations in research and combines them into five general categories. Those five general types of ethical violations are thoroughly examined and discussed. Results - Ethical violations of research occur in various forms at regular intervals; in other words, unethical researchers tend to commit different types of ethical violations repeatedly at same time. The five categories of ethical violation in research are as follows: (1) Arbitrary changes or additions in author(s) happen frequently in thesis/dissertation related publications. (2) Self plagiarism, submitting same work or mixture of previous works with or without using proper citations, also occurs frequently, but the most common type of plagiarism is changing the statistical results and using them to present as the results of the empirical analysis; (3) Translation plagiarism, another ethical violation in publication, is difficult to detect but occurs frequently; (4) Fabrication of data or statistical analysis also occurs frequently. KODISA requires authors to submit the results of the empirical analysis of the paper (the output of the statistical program) to prevent this type of ethical violation; (5) Mashup or aggregator plagiarism, submitting a mix of several different works with or without proper citations without alterations, is very difficult to detect, and KODISA journals consider this type of plagiarism as the worst ethical violation. Conclusions - There are some individual cases of ethical violation in research and publication that could not be included in the five categories presented throughout the paper. KODISA and its editorial office should continue to develop, revise, and strengthen their publication ethics, to learn and share different ways to detect any ethical violations in research and publication, to train and educate its editorial members and researchers, and to analyze and share different cases of ethical violations with the scholarly community.

Objective : The purpose of this study was to conduct a comprehensive survey of children's play in parents of disabled and non-disabled children prior to commencing school. This study aimed to further understanding play recognition and to present a specific direction of play necessary to each parent. Methods : A questionnaire based on prior studies was sent to 700 people who had previously agreed to the take part. A total of 596 questionnaires were analyzed. Uncollected and insincere surveys, of which 106 were questionnaires for parents of disabled children, were exclused from analysis. The SPSS Window 23 program was used for data analysis and frequency analysis and the independent sample T test were performed. Results : Disabled children's parents perceived playing with their children as more important than that of non-disabled children's parents(p<0.01). There was no statistical difference between disabled children and non-disabled children's parents, but there were some differences(p=0,053). Both disabled and non-disabled children had more time to participate with their mothers than with their fathers. Mothers with disabilities had more time to play however, fathers with no disabilities had more time. Both disabled and non-disabled children's parents had the most "ordinary" frequency of buying toys and there was very littele difference between the 2 groups. Both disabled and non-disabled children's parents primarily used the internet to acquire play information, and consideration when buying fun was followed by interest inducement, development level and safety. Conclusion : Through this study, it was possible to compare the status of play recognition and participation by parents of children with or without disabilities. Based on this study, parents will be able to find out what they really need to play and will be provided as a basis for future play studies for children.

Purpose : To evaluate the incidence of arm morbidity following breast cancer surgery including axillary dissection and to identify related factors. Materials and Methods : One hundred and fifty nine patients were studied using a self-report questionnaire and a clinical examination. Lymphedema, reduction of range of motion in shoulder joint and subjective symptoms (pain, impaired arm movement, numbness, stiffness) were evaluated. As related factors, demographic, oncologic characteristics and types of treatment were analysed. Results : The incidence of lymphedema ($\geqq$2 cm difference comparing to unaffected arm) was $6.3\%$, $10.7\%$, $22.5\%$ and $23.3\%$ at each 10 cm, 20 cm, 30 cm, and 40 cm from wrist. Reduction of range of motion in shoulder joint ($\geqq$ 20 degree difference comparing to unaffected arm) was noted In more than 1/3 patients for flexion, abduction and internal rotation. Especially the reduction of range of motion in internal rotation was severe ($>50\%$ reduction) in 1/3 patients. Approximately 50 to $60\%$ of patients complained impaired arm movement, numbness, stiffness and pain. Body mass index (BMI) was the significant risk factor for lymphedema. Conclusion : Lymphedema was present in 1/3 of patients and the common sites of edema were 30 cm 40 cm proximal from the wrist. Also most severe reduction of range of motion in shoulder joint was with internal rotation. There needs weight control for lymphedema because BMI was the significant risk factor for lymphedema. Also rehabilitation program for range of motion especially internal rotation In shoulder joint should be developed.

The purpose of this study was to investigate the relationship between obesity indices, nutritional knowledge, nutritional intake status, and some blood parameters in obese middle-school students. Anthropometric measurement, 24-hour recall for dietary intake, blood analysis and Questionnaire response including nutritional knowledge, nutritional attitude, and self-satisfaction were conducted in 42 obese middle-school students (28 male and 14 female) participated in the nutritional camp program carried by Bucheon district public health center in Kyunggi-do. The mean age of subjects was 13.9 years. The average body weight, BMI, obesity index, WHR and percent body fat were 75.5 kg, 29.1 kg/$m^2$, 30.1, 0.89 and 33.3% in male subjects, and 67.8 kg, 27.5 kg/$m^2$, 25.3, 0.81 and 34.6% in female subjects. The average nutritional attitude, the self-satisfaction and the nutritional knowledge scores were no significant difference between male and female subjects. Average intake of energy were 85.5% of RDA in males and 98.1% of RDA in females. The percentage of energy from fat was higher in both male (29%) and female (26%) subjects than recommended level. Calcium, iron, zinc, vitamin A, vitamin B$_2$, vitamin C, niacin and folate intakes were below the RDA for them. In the results of correlation analysis, body weight, BMI and obesity index were positively correlated with systolic blood pressure and cholesterol intake. There was a negative correlation between percent body fat and nutritional knowledge. Body weight was negatively related to HDL-cholesterol, whereas it has positive relation with RBC, hemoglobin and hematocrit. BMI and obesity index were negatively related to HDL-cholesterol, but positively related to RBC, respectively. WHR showed positive relationship with serum GPT, glucose and MCV.

Purpose: The purpose of the study was to identify the nutrition knowledge, dietary attitudes of guardians, and nutritional status of infants and toddlers as well as the relationships between these variables. Methods: The participants were selected among applicants for low-income family financing provided by the government and included 115 infants and toddlers as well as their guardians. Demographic data, nutrition knowledge, dietary attitudes, and nutrition intakes were assessed using a self-administered questionnaire, biochemical examination, and 24 Hour-Recall method. Results: The score for guardians' nutrition knowledge was 12.97 points of a possible 15, and the score for dietary attitudes was 53.38 points of a possible 75. The nutrition knowledge and dietary attitudes showed significant differences by education level (p < 0.05) and family structure (p < 0.05). Energy intakes of subjects aged 6 ~ 24 months and over 25 months were lower than the DRI for Koreans. The intakes of carbohydrates, protein, and fat of subjects aged 6 ~ 24 months and over 25 months showed no significant differences by level of nutrition knowledge or dietary attitudes. The intake of Ca of subjects aged over 12 months showed significant differences by level of nutrition knowledge (p < 0.05). The intakes of Thiamin of subjects aged 6 ~ 11 months and P of subjects aged over 12 months showed significant differences by level of dietary attitudes (p < 0.05). There was a small positive correlation between education level and nutrition knowledge as well as between dietary attitudes. Nutrition knowledge showed a positive correlation with dietary attitudes. There was a positive correlation between nutrition knowledge and Ca, Riboflavin, as well as Vit C levels. Conclusion: Therefore, it is necessary to consider an educational program for increasing the practical application of knowledge to nutrition management for improvement of nutrition intake in infants and toddlers.

For applying the quality assurance (QA) of volumetric modulated arc therapy (VMAT) introduced in Eulji Hospital, we classify it into three different QA steps, treatment planning QA, pretreatment delivering QA, and treatment verifying QA. These steps are based on the existing intensity modulated radiation therapy (IMRT) QA that is currently used in our hospital. In each QA step, the evaluated items that are from QA program are configured and documented. In this study, QA program is not only applied to actual patient treatment, but also evaluated to establish a reference of clinical acceptance in pretreatment delivering QA. As a result, the confidence limits (CLs) in the measurements for the high-dose and low-dose regions are similar to the conventional IMRT level, and the clinical acceptance references in our hospital are determined to be 3 to 5% for the high-dose and the low-dose regions, respectively. Due to the characteristics of VMAT, evaluation of the intensity map was carried out using an ArcCheck device that was able to measure the intensity map in all directions, $360^{\circ}$. With a couple of dosimetric devices, the gamma index was evaluated and analyzed. The results were similar to the result of individual intensity maps in IMRT. Mapcheck, which is a 2-dimensional (2D) array device, was used to display the isodose distributions and gave very excellent local CL results. Thus, in our hospital, the acceptance references used in practical clinical application for the intensity maps of $360^{\circ}$ directions and the coronal isodose distributions were determined to be 93% and 95%, respectively. To reduce arbitrary uncertainties and system errors, we had to evaluate the local CLs by using a phantom and to cooperate with multiple organizations to participate in this evaluation. In addition, we had to evaluate the local CLs by dividing them into different sections about the patient treatment points in practical clinics.
