Purpose: This study identified the effects of dual-task gait training on balance, gait function, and activity of daily living in patients with Parkinson's disease. Methods: This study used a single-subject design. Two patients with Parkinson's disease participated in this study. Dual-task gait training was performed 1 hour per day 8 times during intervention phase. The subjects were measured 8 times in the baseline phase, 8 times in the intervention phase, and 8 times in the follow-up phase. The outcome measurements included a timed up and go test (TUG), a Berg balance scale (BBS), a 10 meter walk test (10MWT), a 6 minute walk test (6MWT), a dynamic gait index (DGI) and a Korean modified Barthel index (K-MBI). Results: When compared to the average of the baseline process, the data collected during the intervention period showed that the TUG and 10MWT results improved and the tendency line was above the baseline. In addition, BBS, 6MWT, DGI, and K-MBI values for both patients increased remarkably after the training. Conclusion: The results of this study revealed that dual-task gait training may be helpful to improve balance, walking function, and activity of daily living for patients with Parkinson's disease. Further studies need to confirm our findings.

The Purpose Of This Paper Is To Use A Tactile Sensor To Compensate The Error Rate. Most Automated Sphygmomanometers Use The Oscillometric Method And Characteristic Ratio To Estimate Systolic And Diastolic Blood Pressure. However, Based On The Fact That Maximum Amplitude Of The Oscillometric Waveform And Characteristic Ratio Are Affected By Compliance Of The Aorta And Large Arteries, A Method To Measure The Artery Stiffness By Using A Tactile Sensor Was Chosen In Order To Integrate It With The Sphygmomanometer In The Future Instead Of Using Photoplethysmography. Since Tactile Sensors Have Very Weak Movements, Efforts Were Made To Maintain The Subject's Arm In A Fixed Position, And A 40hz Low Pass Filter Was Used To Eliminate Noise From The Power Source As Well As High Frequency Noise. An Analyzing Program Was Made To Get Time Delay Between The First And Second Peak Of The Averaged Digital Volume Pulse(${\Delta}t_{dvp}$), And The Subject's Height Was Divided By ${\Delta}t_{dvp}$ To Calculate The Stiffness Index Of The Arteries($Si_{dvp}$). Regression Equations Of Systolic And Diastolic Pressure Using $Si_{dvp}$ And Mean Arterial Pressure(Map) Were Computed From The Test Group (60 Subjects) Among A Total Of 121 Subjects(Age: $44.9{\pm}16.5$, Male: Female=40:81) And Were Tested In 61 Subjects To Compensate The Error Rate. Error Rates Considering All Subjects Were Systolic $4.62{\pm}9.39mmhg$, And Diastolic $14.40{\pm}9.62mmhg$, And Those In The Test Set Were $3.48{\pm}9.32mmhg,\;And\;14.34{\pm}9.67mmhg$ Each. Consequently, Error Rates Were Compensated Especially In Diastolic Pressure Using $Si_{dvp}$, Various Slopes From Digital Volume Pulse And Map To Systolic-$1.91{\pm}7.57mmhg$ And Diastolic $0.05{\pm}7.49mmhg$.

The medical thesaurus, MeSH (Medical Subject Heading), has been used as a controlled vocabulary thesaurus for English medical paper indexing for a long time. In this paper, we propose an automatic cross language keyword assignment method, which assigns English MeSH index terms to the abstract of a Korean medical paper. We compare the performance with the indexing performance of human indexers and the authors. The procedure of index term assignment is that first extracting Korean MeSH terms from text, changing these terms into the corresponding English MeSH terms, and calculating the importance of the terms to find the highest rank terms as the keywords. For the process, an effective method to solve spacing variants problem is proposed. Experiment showed that the method solved the spacing variant problem and reduced the thesaurus space by about 42%. And the experiment also showed that the performance of automatic keyword assignment is much less than that of human indexers but is as good as that of authors.

This study tried to find out whether character patterns of elderly people are related to stress resistance using brain waves, personal physiological index of cranial nerves. The data were gathered by 1,108 seniors(age 65 and over) who were requested to check brain waves from September, 2007 to December, 2010 in Korean Institute for Research of Psychiatry. 552 of the subject showed the propensity to positive behavior, 556 of them showed the propensity to negative behavior. 735 of the subject showed the propensity to cheerful emotion, 373 of them showed the propensity to depressed emotion. As a result the propensity of emotion was significantly related to the stress resistance, but not the propensity of behavior. In other words, the propensity to cheerful emotion showed higher average stress resistance index than the propensity to depressed emotion. So the person who has the propensity to cheerful emotion can cope with stress better. This study shows the propensity to emotion is related to stress resistance. The influence of the propensity to emotion and how it works should to be studied.

This study sought to contribute to the revitalization of local economy by developing a natural recreation forest, which is the base of ecotourism recreation, through utilizing forest resources and the natural environment of Gwangju-si. The study conducted a feasibility assessment through on-site surveys such as the suitability of the candidate sites, location analysis, and possibility of damage to the forest, before developing recreation forest sites in Gwangju-si and, based on the result, selected appropriate subject sites. The candidates for this study were 5 forest sites such as one site in the Mokheon-dong area, two in the Docheok-myeon area, and one in the Toechon-myeon area. For this study, the current status of the natural recreation forest was surveyed, its feasibility index and assessment process were investigated, and the local status and related regulations of Gyeonggi-do and Gwangju-si were reviewed. The final subject sites were selected after feasibility assessment utilizing assessment index in order to evaluate the candidate sites. The feasibility assessment was conducted after three separate on-site surveys for each candidate site between October 2018 and January 2019 utilizing "The Feasibility Assessment Criteria for Natural Recreation Forest (Notification 2018-71)" of the Korean Forest Service. The items instrumental to the feasibility assessment were classified into landscape, location, water system, induction of recreation, and development condition; the assessment was made after redefining each item into detailed items. Through this process, the Usan-ri area was selected as the final site for developing natural recreation forest, having obtained more than 100 points according to "The Feasibility Assessment Criteria for Natural Recreation Forest" of the Korean Forest Service. In order to develop natural recreation forest in the Usan-ri area in the future, further discussion is necessary with the relevant departments in consideration of the degree of ecological zoning map.

In this study, an educational program was developed so that artificial intelligence could be used as a transdisciplinary convergence education with other disciplines. The main educational content is designed for 8 hours using machine learning to help students understand the molecular structure dealt with in high school chemistry. The program developed in this study calculated the I-CVI (Item Content Validity Index) value through expert review, and as a result, none of the items were rejected with a score of .80 or higher. Because the program of this study combines the content elements of the chemistry subject and the information (artificial intelligence) subject academically, it is expected that the learner will be able to increase the convergence talent literacy. In addition, since it is not required to secure a additional number of hours for this educational program, the burden on teachers may be low.

Purpose : Kinesio taping applied to the ankle varies, and if the overall ankle is taped as much as possible, several effects, including balance, can be expected, but clinically the cost reduction for intervention is very important. Therefore, this study attempted to find out the optimal way to the effect and cost of kinesio taping on ankle dynamic balance. Methods : The subject of this study was 24 university students in their 20s (male: 13, female: 11), who received sufficient explanation of the purpose and method of the study. The Cumberland ankle instability tool (CAIT) questionnaire was used for the degree of ankle instability of the study subjects. If the subject's CAIT score was 28 points or more, it was classified as a stable ankle, and if the score was 24 points or less, it was classified as functional ankle instability (FAI). In this study, Biodex Balance System^® measurement equipment was used to calculate the dynamic balance of study participants. The application of kinesio taping was performed by one physical therapist to attach in the same way, and a method of wrapping the ankle joint was applied in the eight-shaped bandage. Results : The results are as follows in before and after taping of the stable ankle and FAI group. There was no significant difference in the overall, anterior-posterior, and medial-lateral stability index. The comparison is as follows between groups for the differences (post-pre value) in before and after the application of kinesio taping. There were no significant differences between groups in all the overall, anterior-posterior, and medial-lateral stability index. Conclusion : In this study, no significant difference in kinesio taping was found in the dynamic balance of stable ankle and FAI (overall, anterior-posterior, and medial-lateral). It is necessary to continue to study ways to find the maximum effect while minimally attaching them to the application method of ankle kinesio taping.

This informetrics study was conducted to find out the distribution of articles and authors that published in African Journal of Library, Archives and Information Studies [AJLAIS]) from 2009 to 2018; considering the year-wise growth of research articles; authorship pattern and collaboration ratio; subject and geographical distributions of authors; and authors' productivity level. A descriptive informetrics research design was adopted. Quota sampling technique was used to select all the articles published within the ten-year period. Data collected through a self-designed checklist was analyzed using frequency count and percentage. The findings revealed that 141 articles, contributed by 266 authors were published by AJLAIS during the period. An annual average growth of 1.20% was recorded. Overall year-wise authorship pattern revealed that majority of articles (62.41%) published in AJLAIS were multiple authored. Also, articles on Informetrics and ICT dominated the journal. Some subject areas not covered were identified such as: indexing and serial collections management. Average collaborative index across the 10-year period for the journal was 0.62. South Africa and Nigeria were the two major prolific contributors to AJLAIS, just as evidence-based research papers of survey type (65.25%) were the most common to the journal. There should be increased numbers of articles in each edition over the coming years, and awareness should be created by the publishers to familiarize the researchers with the publishing requirements of the journal. Also, LIS researchers should concentrate more on areas usually left untouched by previous studies. The study is original as no other similar study was found on publication pattern of articles in AJLAIS covering a ten year period of 2009-2018. The findings of the study will also serve as a feedback mechanism for the Publisher of the Journal and LIS researchers on how to improve the journal and LIS research in general.
