The purpose of this study is to find the standard value of hand width, of grip strength and of pinch strength by age, sex, and by left hand and right hand and also to find how the general characteristics influences grip strength and pinch strength. Martin Vigorimeter (List No. 17-27-01) was used for measuring grip strength, and the pinch gauge (0∼30 lbs) of B&L engineering for measuring pinch strength. The subjects of this study are the children at the age of three to seven years, who attending the babies' play room, kindergarten and the primary school in Seoul and the Kyungki province area. They all were normally developed without any significant neurology problem. wo hundred girls and two hundred boys were partifipated in this study. They were divided into ten subgroups according to the age of six month interval. Each group consisted of forty children of twenty boys and twenty girls. Analysis of data presents the technical statistics upon the hand width of right and left hand and the grip strength and pinch strength according to the age and sex. Multiple regression analysis using mixed liner model was operated in order to find how the general characteristics (of the age, sex, and side of hand) influence hand width, grip strength, and pinch strength individually. Also, we calculated the correlation among hand width, grip strength and pinch strength under the condition of controlling general characteristics; and to find correlation between the right hand and the left hand of the age and sex, we carried out paired t-test and came to the conclusion as follows: 1. Hand width is significantly increased with the increase of age (p<0.01). The increase of hand width according to age, boy is wider than that of girl significantly (p<0.01), and the right hand is wider than that of the left hand significantly (p<0.01). 2. Grip strength is significantly increased as the age and hand width increased (p<0.01). The increase of grip strength according to the age, boy is stronger than that of girl significantly (p<0.01), and grip strength of the right hand is stronger than that of the left hand(p<0.01). 3. Three-jaw pinch strength is increased as the age, hand width and grip strength are increased(p<0.01). But there is no significant difference of three-jaw pinch strength according to sex and the side of hand(p>0.05). 4. Tip pinch strength is significantly increased as the age and grip strength are increased(p<0.05). The increase of tip pinch strength according to the age, boy is stronger than that of girl significantly (p<0.05), but there is no significant difference between the right hand and the left hand(p>0.05). 5. Lateral pinch strength is significantly increased as the age and grip strength are increased(p<0.01). But the increase of lateral pinch strength, there is no significant difference according to the hand width, sex and the side of hand(p>0.05). 6. The test of correlation among hand width, grip strength and pinch strength showed the correlation between grip strength and pinch strength was stronger than the correlation between hand width and pinch strength(0.3<r<0.7). There was strong correlation between each pinch strength(0.3<r<0.7). Above all, the correlation of three-jaw pinch strength and tip pinch strength was strongest(0.7<r<1.0). 7. The test of hand width according to the age and sex, and the difference between the right hand and the left hand in grip strength and pinch strength showed that there was significant difference against all the test of hand width, of grip strength, and of pinch strength in the age group from seven years and six months to seven years and eleven months than the age group under six years, specially in girls group(p<0.05).

본 연구는 경도인지장애 노인을 대상으로 융합형 맞춤 작업치료 활동프로그램을 실시하여, 경도인지장애 노인의 심리 안정 및 사회참여에 미치는 영향에 대해 알아보았다. 경도인지장애 노인 30명을 대상으로 무작위로 실험군과 대조군으로 각각 15명씩 나누어 6주간 주 2회 총 12회기를 3단계로 나누어 진행하였다. 중재 전과 후의 심리 안정을 알아보기 위해, 한국판 노인우울척도(Korean Geriatric Depression Scale; KGDS)을 실시하였고, 사회참여를 비교하기 위해 Frenchay 일상생활활동 자기평가지수(Frenchay Activity Index; FAI)를 실시하였다. 중재 결과 실험군에서 중재 전과 후에 심리 안정, 사회참여는 증가를 보였으며, 대조군에서는 심리 안정에는 증가를 보였으나 사회참여에서는 증가를 보이지 않았다. 따라서 연구결과 융합형 맞춤 작업치료 활동프로그램은 경도인지장애를 가진 노인의 심리 안정 및 사회참여에 긍정적인 영향을 미친다는 사실을 알 수 있었다. This study aims to examine the effect of Convergence Tailed Occupational Therapy Activities Program (CTOTAP) which is customized to elderly people with mild cognitive impairment on their mental stability and social participation. A total of thirty elderly patients with mild cognitive impairment were randomly divided into a test group and a control group of 15 patients each, undergoing a total twelve sessions of the program (two sessions per week for six weeks) in three steps. In order to investigate the mental stability of the patients before and after the program, the Korean Geriatric Depression Scale (KGDS) was used while the Frenchay Activity Index (FAI) was used to explore the social participation of the patients. According to the findings of this study, there appeared to be an increase in the mental stability, social participation of the test group after the program. In addition, after the program there were differences between the test group and the control group in all of the mental stability and social participation. Therefore, the study has shown that the CTOTAP with customization has positive impact on the mental stability and social participation of patients with mild cognitive impairment.

Objectives The aim of this study was to investigate clinical factors of SQD syndrome by tracking plasma gut hormone (active ghrelin, active Glucagon-like peptide-1(GLP-1), pancreatic polypeptide(PP), total peptide YY(PYY)) profiling of pre-post prandial standard meal between SQD group and normal group. Methods A total of 24 adult participants were consecutively recruited on April 2014. They were diagnosed as either by SQD syndrome or normal by Spleen Qi Deficiency Questionnaire (SQDQ). On the experimental day, blood samplings of 2 ml were repeatedly collected at 6 points from 2 groups for measuring plasma levels of gut hormones. At every point, subjective appetite sensations were self-registered. Results & Conclusions 1. There were significantly lower subjective 'Appetite' (p=0.012) and higher 'Satiety' (p=0.012) in SQD group. At each time point, subjective 'Appetite' was significantly lower at 60 min after breakfast (p=0.034) and 'Satiety' were significantly higher at 15 min (p=0.020) and 120 min (p=0.044) after breakfast in SQD group. 2. There were no significant differences in plasma levels of gut hormones (active ghrelin, active GLP-1, PP, total PYY) between SQD and normal group. Also at each time point, there were no significant differences of plasma levels of gut hormones between SQD and normal group. 3. Changes in plasma levels of gut hormones compared to baseline were not significantly different at each time point between SQD and normal group. Plasma PYY levels compared to baseline increased in SQD group following 15 min and 30 min after breakfast but decreased in normal group. 4. Further investigation is needed to construct gut hormone profiling and in this perspective, we can approach evaluation tool on variable appetite in Traditional Korean Medicine (TKM) syndrome in the future.
