This study aimed to develop educational material on the proper use of plant-based milk alternatives in the form of a card news, based on a focus group interview(FGI) with adult consumers. The FGI participants were individuals who had directly purchased cow's milk, soy milk, or other plant-based milk alternatives within the past three months and consumed them at least once a month. The study consisted of 17 adults between the ages of 19 and 63 years who met these criteria(9 males and 8 females). It was identified what participants were curious about, interested in, and needed information regarding the proper use of plant-based milk alternatives through FGI. A 10-page card news was developed that was highly usable, taking into account the FGI results and the latest literature. In conclusion, this study developed a card news aimed at promoting the proper use of plant-based milk alternatives, which can be easily disseminated online in line with the trends in food consumption and digitization. The results of this study suggest that the continuous development and distribution of educational materials that reflect food consumption trends and maximize their usability should be provided for dietary life education, such as school subjects or out-of-school programs.

The aim of this study was to investigate the effects of computer-based cognitive rehabilitation and traditional cognitive training on the working memory and executive function of patients with mild traumatic brain injury. The sample consisted of 20 patients with mild traumatic brain injury who had received rehabilitation treatment in a rehabilitation unit. The subjects were assigned to either the experimental (n = 10) or control group (n = 10). The experimental group received computer-based cognitive rehabilitation and traditional cognitive training for 60 minutes, whereas the control group received only traditional cognitive training for 60 minutes. Both the groups received their respective interventions for 60 minutes a day and 5 times per week across a period of 4 weeks. Working memory and executive function were assessed using the digit span test (forward and backward), visual memory 1 and 2 of the Motor-free Visual Perception Test-3, trail making test, and Stroop test (A and B) both before and after the intervention. The experimental group showed a significantly greater improvement in visual memory and performance on the Stroop test A than the control group. These findings suggest that computer-based cognitive rehabilitation and traditional cognitive training are more effective in promoting positive changes in the working memory and executive function of individuals with mild traumatic brain injury than traditional cognitive training.

This study aimed to investigate the effect of virtual reality training focus on ADL on upper extremity function and activities of daily living in stroke patients. 20 patients with chronic stroke were included in this study. The participants were divided into the experimental (n=10) or control (n=10) groups. Both groups received conventional rehabilitation therapy for 30 min a day, 5 times per week for 4 weeks. The experimental group also performed virtual reality training focus on ADL for 30 min a day, and the control group performed general virtual reality training for 30 min a day. The Fugl-Meyer Assessment (FMA) and Functional Independence Measure (FIM) scores were evaluated before and after the intervention, and both groups showed significant improvement (p<.05). Compared to the control group, the experimental group showed significant improvement in the FMA wrist score and the FIM total, self-care, and sphincter control scores (p<.05). These findings suggest that virtual reality training focus on ADL may have a positive effect on wrist function and overall ADLs compared to that using general virtual reality training in stroke patients.

One of the major ocular complications of diabetes mellitus(DM) is retinopathy, which is characterized by increased neovascularization and neural degeneration in the retina. In the present study, we investigated the effects of treadmill exercise on retinopathy in the rats with DM. Thirty-two male Sprague-Dawley rats were divided into four groups(n = 8 in each group): control group, exercise group, DM-induction group, and DM-induction and exercise group. DM was induced by intraperitoneal injection of streptozotocin. The rats in the exercise groups were made to run on the treadmill for 30 min five times per a week, during 12 weeks. The expressions of phosphoinositide 3-kinase(PI3K), phospho-protein kinase B(pAkt), hypoxia inducible factor-1α(HIF-1α), and vascular endothelial growth factor(VEGF) in the retina were determined using western blot analysis and immunohistochemistry. In the present results, the expressions of PI3K, pAkt, HIF-1α, and VEGF in the retina of the diabetic rats were increased. Treadmill exercise suppressed HIF-1α and VEGF expressions through inhibition of PI3K/pAkt pathway in the diabetic rats. These results suggest that treadmill exercise may ameliorate the progression of diabetes-induced retinopathy by inhibiting neovascularization in the retina.

This study is an experimental study to examine the effect of the 1:1 coaching and example ideas with the GROW model on the creativity of new product ideas. Participants were composed of 32 adults who did not know coaching and were not related to new product development-related industries, and the experiment was randomly assigned to 1:1 coaching group, example idea group, and control group. The ideas answered by the participants were evaluated by measuring novelty, appropriateness, and willingness to pay after the experiment, and 30 experimental data and 3 expert group evaluation data were used for the final analysis. As a result of the study, the 1:1 coaching using the GROW model had a significant effect on the creativity of new product ideas, and in particular, had a positive effect on novelty. The example idea group received the lowest score among the three groups, including the control group, in novelty and suitability, and was found to have a negative effect on idea creativity. Based on these results, implications and limitations for the use of coaching in the work or situation of presenting creative ideas were discussed, and suggestions for follow-up studies were made.

This study was carried out to determine agronomic and genetic characteristics of the production process in tropical yams(Dioscorea alata L.). To make clear the possibility of cultivation of tropical yams in the Suwon area, the growth of the aboveground parts and the enlargement of tuber of Dioscorea alata, were investigated. The aboveground parts of the plants whose sprouted mother tuber were planted in late April were grown slowly until the 70-days after planting and grown rapidly after. From about 50-days after plantation, total length of vines slowly decreased due to the burning of the branch vines of lower modes. With regard to the branching progressed to 4th for the solo yam and to 6th for purple yam. The secondary branches tended to grow better. When the formation of daughter tubers was observed at the 50-days after planting, their enlargement was very slow. The rapid growth of tubers began at the 40-days and continued to the 90-days. General components such as protein, fiber, and lipid were higher in D. opposita rather than in D. alata. Hardness of D. alata was 2696.2 while that of D. opposita was 4946.9. Lightness of D. alata was 73.99, being higher than that of D. opposita.

Tuber yield and content of general component and diosgenin which is a main bioactive property were investigated in order to determine the growth characteristics of round typed yam(Dioscorea opposita L.) and the potential of artificial culture at Suwon, Korea. Tubers of round yam was initiated to form at 60 days after planting and then enlargement of tubers lasted by 160 days after planting. Compared to short typed yam(108g), tuber weight of round yam was higher(127g) on the basis of dry weight at 200 days after planting. In comparison of general component between round yam and short yam, protein of round yam(3.62%) was higher than short yam(2.10%). Water content in round yam(64.5%) was lower in short yam(79.4%), indicating a higher dry weight ratio of round yam. Hardness of round yam was 2787.6 while short yam showed about two times higher hardness(4946.9). Lightness was higher in round yam(77.4). In tuber extracts analysis, diosgenin content was respectively 3.32% in round yam and 2.61% in short yam.

This study investigated the factors influencing the perceptions that military officers can harbor regarding persons who stutter in terms of how well they can adapt to the army. In total, 89 participants were randomly assigned to each of the three different conditions ("fluent speech"=23, "mildly stuttered speech"=34, and "severely stuttered speech"=32). Subsequently, the participants were asked to listen and rate each sample in terms of "the speaker's communicative functioning (i.e., speech fluency, intelligibility, naturalness, speech rate), personal traits (i.e., likeability, anxiety level, intellectual level, and sociability), and the perceived degree of the adaptability to the army." The results showed that significant differences were found between "fluent speech" and "severely stuttered speech" in the perceived communicative functionings and the perceived adaptability to the army. Moreover, there were significant differences in the same variables between "mildly stuttered speech" and "severely stuttered speech." However, there were no significant differences between "mildly stuttered speech" and "fluent speech." Following the conducting of the Pearson correlation test, strong correlations were also found between the perceived communicative functionings, in particular "speech fluency," and the perceived adaptability to the army. Those results can be employed to argue that the communicative functionings can serve as factors which influence the perceptions of persons who stutter in terms of how well they can adapt to the army. Further discussion has taken place regarding the relationship between the perceived communicative functionings and the perceived adaptability to the army.

Weighted committed dose equivalents($W_T\;H_{50}$) per intake of unit activity of four nuclides-I-131, I-133, Cs-134 and Cs-137-, which was based on the concepts of ICRP Pub. 30, are calculated for adult who is 70 kg and 25 years old and, for infant who is 10 kg and 1 year old. Metabolism of iodine taken through oral or inhalation pathway is described by using the three-compartment model which consists of inorganic, thyroid and organic compartment. After intake, the amount of iodine in every compartment is calculated by solving the transfer equations among the these compartments. As soon as caesium is taken into the body, it is distributed uniformly in the body through the transfer compartment. In this case, the amount of caesium in total body is calculated by using the total body compartment model which is divided into two tissue compartments because of their different biological half-lifes of caesium in body. As a result of calculations, whether oral or inhalation pathway, the values of ($W_T\;H_{50}$) per intake of unit activity of I-131 for infants are about ten times as much as those of adults. On the other hand, for Cs-134 and Cs-137, the values of $W_T\;H_{50}$ per intake of unit activity show that, whether adults of infants, they have almost the same values.

To investigate the effects of type of exercise on inflammatory factor and vascular endothelial growth factor in middle aged women, we recruited 18 people middle-aged women and they divided into 3 groups (N=6, resistance exercise group, 40-60% of 1RM, N=6 aerobic exercise group, 60-70% of VO2max, N=6, flexibility exercise group, 10-60 sec/sets). The data were compared to the effect of exercise between 50 ~ 60 minutes per a day, 3 day times per week on the body composition, inflammatory factor, vascular endothelial growth factor and vascular compliance in middle aged women. First, in regards to inflammatory factors between groups, a significant difference (p<.05) was identified in the effects of CRP and IL-6 in terms of time (T). Second, regarding vascular endothelial growth factors between groups based on the type of exercise, a significant difference (p<.05) was found in the effects of VEGF's time (T) and the interaction between time and group (TxG). In conclusion, All types of exercise could partially improve inflammatory factors and vascular endothelial growth factors.
