This study was intended to analyze how well people with right hemisphere damage can understand Korean proverbs. This study used a between-subject design and within-subjects design where all subjects participate in the three experiments for 10 hospitalized patients of whose average age is 66.1 years old and 10 normal adults in the same age range. Experiment 1 was to make up Korean proverb related stories and suggest it in written, Experiment II was to suggest a picture presenting a Korean proverb and the proverb itself directly, and Experiment III was to make up a story related to a Korean proverb and tell it auditory. Five Korea proverbs were used for each experiment; 15 in total. The results were as follows: First, there was a significant difference in understanding of Korean proverbs between normal adults and people with right hemisphere damage. Second, there was no significant difference of understanding between them by stimulating methods to suggest Korean proverbs. Third, people with right hemisphere damage had a tendency to interpret Korean proverbs literally as a total wrong reaction was composed of 55.36%. Considering the above the results, it can be said that people with right hemisphere damage have less understanding of Korean proverbs than normal adults, which is not affected by a way of or a condition of suggesting Korean proverbs in people with RHD, and they are inclined to make literal interpretation of Korean proverbs as they are.

Hearing impaired people are living in a voice culture area, but due to the difficulty of communicating with normal people using sign language, many people experience discomfort in daily life and social life and various disadvantages unlike their desires. Therefore, in this paper, we study a sign language translation system for communication between a normal person and a hearing impaired person using sign language and implement a prototype system for this. Previous studies on sign language translation systems for communication between normal people and hearing impaired people using sign language are classified into two types using video image system and shape input device. However, existing sign language translation systems have some problems that they do not recognize various sign language expressions of sign language users and require special devices. In this paper, we use machine learning method of artificial neural network to recognize various sign language expressions of sign language users. By using generalized smart phone and various video equipment for sign language image recognition, we intend to improve the usability of sign language translation system.

Bipolar disorder is a mental illness characterized by extreme mood and behavioral swings, such as highs of euphoria and lows of depression. It is a socially significant disorder in which people with the disorder experience intense mood swings and, for those with severe bipolar disorder, it is even difficult leading a normal life. High stress levels in people with mental illness can lead to neuroendocrine disruption, and it is strongly linked to aging. When the neuroendocrine system becomes vulnerable to these mental illnesses and stress, it is likely to accelerate aging. And it's the epigenetic clock that can measure the extent of this accelerated aging. The Epi clock, a pan tissue clock, measures aging through DNA methylation, and the degree of methylation is modified and changed by environmental conditions in the body. Therefore we wanted to check the changes in the epigenetic age of the patients with bipolar disorder. While we found no significant differences in epigenetic age, we did confirm the possibility that people with bipolar disorder have different methylation than normal people. We also found that the EPIC array data fit better on the Epi clock than on the Horvath clock with age-accelerated data from normal people.

The purpose of this study was to the kinetic variables effects from the use of arch support inserts on low-arched people. We selected 10 people for the research and separated them into 2 groups, 5 people for the normal arched group and 5 people for the low arched group. Each group wear shoes which have a 3 step convertible arch support (level 0, level 2, level 5) and we measured their foot pressure and 3D motion analysis data. As a result, we found that the mean pressure at the heel of the low arched group was decreased when using the arch supports. The arch support induced the correct grounding area for the foot and dispersion of foot pressure. 3D motion analysis found that as the height of the arch support was increased, the movement of the Y-axis(inversion-eversion) was increased to relieve the shock to the heel. The arch support insert limited the range of motion(ROM) of the Z-axis(abduction-adduction) of the low arched person's ankle joint and prevented ankle injury caused by the excessive eversion when walking. Low arched people are seen to be easily tired due to the ineffective shock absorption of the knees and abnormal walking motion. In order to improve the problems, a 3 step convertible arch support(level 5) insert would improve the low-arched people's walking ability. In other words, the low arched people should be expected to walk as well as normal arched people when they wear shoes with the arch support insert.

The purpose of this study is to evaluate the difference about pathogenesis of normal person and traffic accident, author used DSOM to investigate pathogenesis. Patient group is consisted of people who one month does not pass from traffic accident, and normal group is consisted of people who do not have special symptoms and past history. DSOM was used for pathogenesis investigation of two group. There was significant difference between T.A. group and Normal group in deficiency of blood (血虛), stagnation of qi(氣滯), blood stasis(瘀血), dampness(濕), dryness(燥), liver (肝), heart(心), kidney(賢), phlegm(痰)(p<0.05). When it comes to comparison of sex, there was significant difference between male and female in dryness(燥), spleen(脾), and lung(肺)(p<0.05) in T.A. group. But in normal group, there was not significant difference between male and female, and in the case of male there was significant difference between T.A. group and normal group in deficiency of blood(血虛), stagnation of qi(氣滯), kidney(賢), phlegm(痰)(p<0.05). Also in the case of female there was significant difference between T.A. group and normal group in blood(血虛), stagnation of qi(氣滯), blood stasis(瘀血), dampness(濕), dryness(燥), kidney(賢), phlegm(痰)(p<0.05). This result showed that the pathogenesis are differs. This result showed that the pathogenesis of traffic accident patient and normal people are difference.

It is known fact that the CTS patients have lower pinch strength than the normal people. And we can assume that the sensory nerve action potential(SNAP) and the nerve conduction velocity(NCV) of the CTS group are lower or slower than the normal subjects. This paper analysed the grip strength and performed EMG experiment for the group Norm, G1 and G2. The results are as follows: 1) CTS patients have lower pinch strength than normal people. 2) There was no significant difference on SNAP between the CTS group and the normal group. 3) There was significant difference on NCV among Norm, G1, and G2 group. Especially, significant level was higher in the evening after the continuous use of wrist.

In such special or precious occasions as a wedding ceremony, brides, handicapped or not, wish to wear a beautiful wedding dress. However, an ordinary wedding dress is not suitable nor convenient to a bride who has a bodily impediment. A one-piece type wedding dress, which even a normal bride needs assistants to help her wear, will create more inconvenience to crippled females. In this connection, this study is purposed to convert a normal ready-made wedding dress design into one suitable to the bodily handicapped females. For handicapped people on a wheelchair who generally put on and off a wedding dress while sitting on the chair, a one-piece type wedding dress is divided into the top and the skirt to make it a two-piece type wedding dress which is easy to get into and take off. The top should be separated from the skirt in such a manner that the wearer may not be aware of the division of the two pieces but easily put on and off since the sides or back of the top is opened. An opening is also given to the sides of the skirt so that handicapped people may sit on the skirt on the chair and then close the opening by themselves. Converting ready-made wedding dress design into functional clothes for handicapped people is really significant in that ready-made clothes can be recycled, their production cost reduced, and the economic burden of handicapped people relieved.

Purpose: We attempt to assess the differences in the degree of lumbar lordosis in patients with lower back pain caused by the herniation of the nucleus pulposus and in normal people (divided into male and female groups). Methods: This study was conducted with 14 patients (7 males, 7 females) diagnosed with, and being treated for, lumbar herniated nucleus pulposus and 14 normal people (7 males, 7 females). In order to examine the degree of lumbar lordosis in these subjects, hip flexor lengthening tests were conducted and the lumbar curves were measured in three postures (supine, sitting, and prone) and the results were compared. Results: The measured values of the curves for the standing and prone postures showed statistically significant differences between the normal group and the patient group, between the normal male group and the male patient group, and between the normal female group and the female patient group (p<0.05). Conclusion: The measurement method that uses flexible curve rulers in the standing or prone postures can be usefully utilized in assessing the lumbar lordosis of patients with lumbar herniation of the nucleus pulposus.
