Normal pressure hydrocephalus (NPH) is a condition wherein the cerebrospinal pressure in the brain is within the normal range, but the cerebrospinal fluid increases above the normal level, causing ventriculomegaly. In patients with NPH, the articulatory system exhibits reduced mobility and range, which may affect diadochokinesis (DDK) and speech intelligibility. In this study, we investigated the characteristics of DDK, including accurate-token DDK and all-token DDK including inaccurate tokens, in patients with NPH and healthy elderly adults (HE). We also examined the classification accuracy of DDK between the two groups. Finally, we investigated whether there was a correlation between speech intelligibility and DDKs in the NPH group. The results showed that NPH and HE groups differed significantly in both accurate-token DDK and all-token DDK, and their classification accuracy was relatively high. However, there was no correlation between speech intelligibility and DDK. The findings suggest that the DDK is a useful method for sensitively assessing speech motor performance in patients with NPH.

The purpose of this study was to determine the effect of grit on the resilience of elementary science gifted and general students in their daily lives, and to identify the differences between science gifted students in university gifted centers and elementary school gifted classes and normal students. The grit and resilience test was administered to 154 scientifically gifted students and 98 non-gifted students. Based on the collected data, descriptive statistical analysis, measurement model analysis, and multigroup structural model analysis were conducted. The results of the study were as follows: First, across all sub-factors of grit and resilience, the gifted students showed significantly higher levels of resilience than non-gifted students. Second, the path from making perseverance of effort in grit to resilience showed a positive effect, while the path from consistency of interest in grit to resilience showed a negative effect. Third, in all groups, including regular classes, the school for gifted, and the university-affiliated gifted students, the perseverance of effort in grit exhibited a positive effect on resilience, and the consistency of interest in grit showed a negative effect on interpersonal relationship skills in resilience for both the non-gifted and the gifted students. Lastly, gifted students showed a significant difference in the path from perseverance of effort in grit to the sub-factors of resilience, whereas non-gifted students did not.

An understanding of the influence of emotional context on memory retrieval is crucial to our comprehensive understanding of human cognition. While previous research focused primarily on visual stimuli to address this relationship, this study ventures into the realm of speech-based emotional contexts. Building on previous findings, we examine the effects of arousal and the valence of verbal contexts on memory, with particular focus on mitigating the serial position effect. In Study 1, we investigated how the arousal level of verbal context in the middle of a word list affects memory retention. Our results demonstrated detriment to the memory of later parts of the word list when exposed to low-arousal contexts. In Study 2, we controlled for arousal levels and examined the impact of valence on memory. We found that negative verbal contexts impair the memory of the word when presented together. Our findings suggest that speech-based emotional contexts do not facilitate verbal memory processing. In particular, negative emotional contexts were found to reinforce the serial position effect. Negative emotional contexts tend to disrupt task performance and fail to elicit memory-enhancing effects, especially when both the context and memory stimulus are verbal. These insights offer a valuable contribution to our understanding of the nuances of auditorily delivered emotional context in verbal memory processes.

The aim of this study is to identify the competencies required for fashion-related majors that meet contemporary demands, align with the objectives of university education, and reflect the qualities desired in graduates. To achieve this goal, we conducted content analysis of relevant data and in-depth interviews with experts. First, the content analysis involved coding key information from the introductions, educational goals, desired qualities of graduates, and curricula published on the websites of both South Korea and international fashion-related universities. Additionally, we analyzed the National Competency Standards (NCS) and the Meta-goals of higher education programs set by the International Textile Apparel Association (ITAA), extracting six core competencies. Second, in-depth interviews were conducted with six experts, each with 23 to 31 years of experience in Korean and international apparel industry and academia. The interviews were recorded, transcribed, and keywords were extracted. To ensure the validity of the coding results, cross-checks were performed among the researchers. The analysis identified the following competencies: empathic communication, social responsibility, professional thinking, creative and integrative thinking, global perspective, and challenging leadership. Based on these findings, establishing competencies that meet contemporary demands and developing corresponding curricula are essential steps towards creating a feedback system. Future research should focus on developing and implementing curricula that foster a virtuous cycle, ultimately enhancing students' competency levels.

Indoor localization is a critical component for numerous applications, ranging from navigation in large buildings to emergency response. This paper presents an enhanced Pedestrian Dead Reckoning (PDR) scheme using smartphone sensors, integrating neural network-aided motion recognition, Kalman filter-based error correction, and multi-sensor data fusion. The proposed system leverages data from the accelerometer, magnetometer, gyroscope, and barometer to accurately estimate a user's position and orientation. A neural network processes sensor data to classify motion modes and provide real-time adjustments to stride length and heading calculations. The Kalman filter further refines these estimates, reducing cumulative errors and drift. Experimental results, collected using a smartphone across various floors of University, demonstrate the scheme's ability to accurately track vertical movements and changes in heading direction. Comparative analyses show that the proposed CNN-LSTM model outperforms conventional CNN and Deep CNN models in angle prediction. Additionally, the integration of barometric pressure data enables precise floor level detection, enhancing the system's robustness in multi-story environments. Proposed comprehensive approach significantly improves the accuracy and reliability of indoor localization, making it viable for real-world applications.

This study was carried out to investigate the effect of memory impairment in rats fed alcohol liquid diets. The rats were randomly divided into 4 groups. While the control(C) group received a diet containing 12% of the daily calories with isocarbohydrate, the other groups received a diet containing 12% of the daily total calories with 36% Soju (A), 25% Cynanchi wilfordii radix liquors (WA), and 25% Polygoni multiflori radix liquors (RA) for 6 weeks. After 6 weeks, ADH activity in the brain tissue of the Group A was found to be significantly lower than Group C but significantly higher than both Groups WA and RA(p<0.05). ADLH activity was revealed to be the highest in the Group WA (p<0.05). The concentration of acetaldehyde, a highly toxic metabolite, was the highest in the Group A, but its concentration decreased significantly if fed a liquid diet containing WA. The concentration of acetylcholine, which has a high correlation with memory impairment, was significantly lower in Group A, although Group RA group was the highest compared to the other groups (p<0.05). AChE activity of the Group A was higher than Group C but lower in Groups WA and RA (p<0.05).

Special Practitioner exists based on the need for special fields that are required to manage difficult patients with specialized skills distinguished from General practitioner. The purpose of dental specialist system is to manage patients who are not treatable by general practitioner by training doctors specializing in one specific field, thereby, enhancing health of the public. Oral Medicine deals with orofacial pain, oral soft tissue disease, forensic dentistry, oral diagnosis. In these days, living environments of city life bring about increase in stress which ultimately lead to increase in prevalence of temporomandibular disorder, oral soft tissue disease, neuropathies such as trigeminal neuralgia, and hence, the number of patients seeking help of those symptoms tend to increase. The purpose of this study was to analyze the rate of referrals and the routes of patients seeking help by investigating 3,707 patients who visited Department of Oral Medicine, College of Dentistry, Yonsei University, from August, 2004 to April, 2005. The results were as follows: 1. The types of disease referred to the Department of Oral Medicine were orofacial pain, oral soft tissue disease, forensic dentistry, oral diagnosis. 2. The rate of referrals was 58.51% which implies that more than half of the patients visiting the Department of Oral Medicine were referred. 3. The types of institution which made referrals were analyzed, and as a result, dental clinics made most of the referrals with the rate of 83.23%, while that from medical or oriental medical institutions was 16.78%. 4. Among the patients who visited the Department of Oral Medicine on their own, 30.52% gained the information about the Department of Oral Medicine from internet and mass media, and from neighbors. From the above results, most of the patients visiting the Department of Oral Medicine were found to be referred not only from the field of dentistry but also from the field of medicine. These suggest that Oral Medicine manages patients who are not treatable by general dental practitioners, and medical specialists tend to cooperate with the Department of Oral Medicine to manage diseases associated with Oral Medicine. Therefore, the role of Oral Medicine can be considered to be important as a special field, and the results of this study should be considered when working out a policy of Dental specialist system on demand and supply of residents in the future.

The purpose of this study is to investigate the differences of science achievement between female- and male students in different assessment types, expecting the reconsideration of their scientific ability. to accomplish this purpose, the school science achievement score of 1,487 female- and male students in 2000 were analyzed from the perspectives of assessment methods and gender differences, achievement level and gender differences, and gender characteristics in correlation between each assessment type and total science score. The science achievement score in this study includes mi-term and final paper-and-pencil test in two semesters and performance assessment. The results are as follows. First, in the total science achievement score, whereas female students achieved significantly better than male counterparts in the 7th grade, there was no significant difference between two genders in the 8th and 9th grades. Second, as for the close-ended items, all students, regardless of their gender and grade, showed no significant difference. As for the open-ended items, whereas female students achieved significantly better than male counterparts in the 7th grade, there was no significant difference between gender in the 8th and 9th grades. As for the performance assessment, all female students, regardless of their achievement level, achieved significant better than male counterparts, which is very noteworthy. Third, in the uppermost achievement level, there was no significant difference not only in close- and open ended items but also in performance assessment. Fourth, male students' correlation between performance assessment and total science score was relatively higher than female students'. The result of this study, that female students did significantly better than male students in performance assessment, is interesting in that performance assessment is widely accepted as more reliable and valid method in measuring students' various ability than traditional paper-and-pencil test.
