Blenderbot 2.0 is a dialogue model representing open domain chatbots by reflecting real-time information and remembering user information for a long time through an internet search module and multi-session. Nevertheless, the model still has many improvements. Therefore, this paper analyzes the limitations and errors of BlenderBot 2.0 from three perspectives: model, data, and dialogue. From the data point of view, we point out errors that the guidelines provided to workers during the crowdsourcing process were not clear, and the process of refining hate speech in the collected data and verifying the accuracy of internet-based information was lacking. Finally, from the viewpoint of dialogue, nine types of problems found during conversation and their causes are thoroughly analyzed. Furthermore, practical improvement methods are proposed for each point of view, and we discuss several potential future research directions.

Objective : The purpose of this study is to consider the change of hand function according to the quality of sleep and to find out a correlation among the quality of sleep and hand function, and sleep disturbing factors. Method : 23 patients who were hospitalized more than 6 months from Nov. 2017 to Jan. 2018 were tested for the quality of sleep used by sleep quality scale, for the grip strength used by a dynamometer, and for the coordination used by BBT and 9-Hole Peg test. The collected data were analyzed to implement the paired t-test and Pearson correlation coefficient. Result : In the high grade group of sleep score, the quality of sleep & BBT, and the grip strength & BBT have correlated each other; and in the medium group, only the latter has shown a correlation. In both groups, the quality of sleep and the sleep pattern have showed significant high correlation. Conclusion : When the elderly in geriatric hospitals show qualitative differences, BBT and the combination of treatment for the improvement of grip strength can improve the quality of sleep. And the sleep pattern intervention is considered to be effective to improve the quality of sleep.

Typical algorithms of deep learning include CNN(Convolutional Neural Networks), which are mainly used for image recognition, and RNN(Recurrent Neural Networks), which are used mainly for speech recognition and natural language processing. Among them, CNN is able to learn from filters that generate feature maps with algorithms that automatically learn features from data, making it mainstream with excellent performance in image recognition. Since then, various algorithms such as R-CNN and others have appeared in object detection to improve performance of CNN, and algorithms such as YOLO(You Only Look Once) and SSD(Single Shot Multi-box Detector) have been proposed recently. However, since these deep learning-based detection algorithms determine the success of the detection in the still images, stable object tracking and detection in the video requires separate tracking capabilities. Therefore, this paper proposes a method of combining Kalman filters into deep learning-based detection networks for improved object tracking and detection performance in the video. The detection network used YOLO v2, which is capable of real-time processing, and the proposed method resulted in 7.7% IoU performance improvement over the existing YOLO v2 network and 20 fps processing speed in FHD images.

This study is to structurally analyze the effect of authoritative, authoritarian, and permissive three-dimensional parenting behavior on pragmatic language ability in the field of child language development by using data from the Panel Study on Korean Children, which was completed and published in 2018. As a result of the study, looking at the effect of three-dimensional parenting behavior on children's language ability, first, the authoritative parenting behavior, which provides a clear direction for parents in raising their children, and takes a rational and consistent way, is effective in improving pragmatic language ability appeared to have a positive effect. Second, it was found that authoritarian parenting behavior that strictly controls children's behavior in the direction desired by parents and demands absolute obedience from children did not have a significant effect on the improvement of children's pragmatic language ability. Lastly, it was found that the permissive parenting behavior of the neglect type, which allows children to do whatever they want, has a negative effect on the children's pragmatic language ability. Based on these results, in order to equip children who will live in an era where creativity and problem-solving ability are important to have the ability to express themselves accurately, parenting behavior, which is a very important ecosystem for children's language development, needs to be done correctly.

The purpose of this study was to examine the effects of whole-body vibration exercise for life care on balance and walking ability in the fall risk stroke patients. 30 stroke patients were divided into two groups, Otago exercise group(n=15) and whole-body vibration exercise group(n=15). Walking ability were measured by 10m walking and Tinetti mobility test with stroke patients and balance ability were measured by BBS and TUG on comparative analysis of pre, post exercise. To compare differences before and after the program, a paired t-test was used and to compare differences between both groups, an independent samples t-test was used. As a result of the test, it was discovered that BBS and Tinetti mobility test of the both groups were increased statistically significantly and TUG and 10m walking test of the both groups were decreased statistically significantly. balance ability and walking ability of the whole-body vibration exercise group were improved statistically significantly in comparison with those of the Otago exercise group. The results of this study showed that whole-body vibration exercise for the improvement of life care had significant effects on improving BBS, TUG, 10m walking and Tinetti mobility test of fall risk stroke patients. Therefore, it is recommended to apply whole-body vibration exercise to improve life-care through improving balance ability and walking ability of fall risk stroke patients.

Hereditary tyrosinemia type 1 (HT-1) is a metabolic disorder caused by biallelic pathogenic variants in the fumarylacetoacetate hydrolase (FAH) gene, which impairs the function of the FAH enzyme, resulting in the accumulation of tyrosine's toxic metabolites in hepatocytes and renal tubular cells. As a consequence, individuals with HT-1 exhibit symptomatic manifestations. Rapid diagnosis and treatment of HT-1 can prevent short-term death and long-term complications. A 15-day-old boy presented to the outpatient department with elevated levels of tyrosine on his newborn screening tests conducted at the age of 3 and 10 days, respectively. Further blood tests revealed increased levels of alpha-fetoprotein and amino acids including tyrosine and threonine. Urine organic acid tests indicated a significant elevation in tyrosine metabolites, as well as the presence of succinylacetone (SA), which led to the diagnosis of HT-1. Two pathogenic and likely pathogenic variants of FAH compatible with HT-1 were also detected. He began a tyrosine-restricted diet at one month old and received nitisinone (NTBC) at two months old. With continued treatment, the patient's initially elevated AFP level, detection of SA in the urine, and mild hepatomegaly showed improvement. During four years and seven months of treatment, there were no exceptional complications apart from an increase in tyrosine levels and a delay in speech. We report a case of tyrosinemia type 1 detected through newborn screening, treated with dietary restriction and NTBC, with a good prognosis.

Objective : The aim of this study was to evaluate the current knowledge regarding constraint-induced movement therapy (CIMT) and its application in clinical practice by physiatrists and therapists in pediatric rehabilitation area in Korea. Methods : Online survey via E-mails was sent to a total of 510 members (204 physiatrists and 306 therapists) of the Korean Society of Pediatric Rehabilitation and Developmental Medicine (KSPRDM). Results : The response rate was 35.1% (179 of 510). A total of 179 questionnaires was completed by 39 physiatrists, 89 physiotherapists, 48 occupational therapists, and 3 speech therapists. 45.8% of responders had worked over 6 years in the pediatric rehabilitation setting and a total of 58.1% (n=104) of the sample had used CIMT. The main limitations of clinically applying CIMT included limited staff and inappropriate clinical setting (35.1%, n=61), lack of understanding (19.5%, n=34), and developmental issues of function on the unaffected side (13.8%, n=24). The cooperation of patients (77.6%, n=76), cognitive/behavioral factors (42.9%, n=42), and cooperation of caregivers (25.5%, n=25) were the 3 major concerns that could be limitations with CIMT. Conclusions : Although considerable evidence supports the use of CIMT, many of physiatrist and therapists do not apply this method in practice. The improvement of limitations is necessary for wide use of CIMT in clinical practice in Korea.

This study was made on 274 apoplectics patients who received the rehabilitation therapy and tests on physical, psychological and social adaptations as outpatients in 23 general hospitals in the Seoul and Kyungi area. The basic data on degree of improvement of apoplectic patients studied from rehabilitation therapy. Data was collected over a period of 63 days, from February 21st till April, 23, 1996. The assigned physical therapist conducted direct interviews with patients after he answered the distributed questionnaires for each individual patient. The colleted data was processed by the $SPCC/C^+$ method. The results of the tests conducted to meascne the the degree of ADL dependency, depression and social activity corresponding to the physical, psychological, and social adaptation. The details are ; 1) The test to meascne the degree of ADL dependency, corresponding to the study of physical adaptation of CVA patients, indicated a mean score of 2.57(ideal score is 1.0) with a standard deviation of ${\pm}0.75$. The worst score was 3.95 while the best score was a perfect 1.0, representing a severe range of dependency. The distribution was centered with a median of 2.65 and a mode of 2.68. 2) The test to meascne the degree of depression which corresponds to the level of psychological adaptation yielded a mean of 2.99 which is higher than the normal limit of 2.45. The standard deviation was ${\pm}0.52$ and the worst score and the best score were 4.35 and Respectirdy. The distribution was centered with a median of 3.00 and a mode of 3.00. 3) The test to meascne the degree of social activities for the level of social adaptation indicated a very low mean score of 26.52 (perfect score is 144), with the standard deviation of ${\pm}16.23$. Some patients scored as high as 100, but others scored as low as 3. The distribution of social activities at a very low level was shifted to the left with a median of 24.00 and a mode of 20.00. 4) Factors influencing the level of physical, psychological and social adaptation are as follows : Factors significantly influencing the level of physical adaptation measured by ADL dependency are age, personal guardian, payer of medical expenses, and paralysis of the right arm, right leg and facial paralysis. Factors significantly influencing the level of psychological adaptation measured by the degree of depression, are age, marital status, education, medical history of individual and family, speech impediment, and facial paralysis. Factors significantly influencing the level of social adaptation measured by the degree of social activity are age, marital status, education, employment status, and the burden of medical expense. 5) The Corelationship is significant(9.00), between ADL dependeing as degree of physical adaptation and depreseion as degree of psychologial adaptation. ADL dependency is proportional to depression. But social activity is inversely protional to ADL dependeny and depression. In conclusion, the increased care for physical function of the patients is not the only necessary means to better facilitate the appropriate adaptation of CVA patients. The introduction of a solid rehabilitation program for psychological and social adaptation will also play the integral part of the treatment of CVA patients.
