Purpose : The purpose of this study was to provide the material about the treatment effect of hand function training and writing training being performed as a part of treatment to improve the function of the non-dominant hand of the patients whose dominant hand is damaged and thus need to improve their non-dominant hand's function. Method : During one month of November, 2013, this study randomly chose five study subjects for hand function training, five for writing training, and ten of control group from 20 normal male and female adults going to K Univ. in Busan. All study subjects fully understood all of the training course, agreed to take the test in this study, and volunteered to participate in the test. Each training was performed five times for two weeks, 30 minutes each time. For measurement, Purdue pegboard was used to look into the change of hand dexterity. To investigate an improvement in hand function through hand function training and writing training, this study conducted early evaluation before training, interim evaluation, and final evaluation. Result : First, according to the comparison of dominant hand dexterity by group and by method during a training period, the groups of hand function training and of writing training improved dominant hand dexterity more than the control group. Secondly, according to the comparison of non-dominant hand dexterity by group during a training period, the groups of hand function training and of writing training improved dexterity more than the control group. According to the comparison of non-dominant hand dexterity by method during a training period, there was no big difference in dexterity between the groups of hand function training and of writing training and the control group. But, the group of hand function training showed a further improvement. Thirdly, according to the comparison of both-hand dexterity by group and by method during a training period, the groups of hand function training and of writing training improved both-hand dexterity more than the control group. Fourthly, according to the comparison of both-hand handling ability by group and by method during a training period, the groups of hand function training and of writing training improved both-hand handling ability more than the control group. Conclusion : Given the study result, it is considered that hand function training and writing training help brain damaged patients improve their hand function for their daily activity. And it will be meaningful to research brain damaged patients' motor skills after their brain damage, and the patients who have low abilities of visual perception and cognition. In the future, it will be necessary to secure more study subjects and perform systematic training during a sufficient test period.

This study investigated the effect of aftertreatments such as using the softener or starch on the mechanical properties of knitted fabrics. The mechanical properties of fabrics, hand value(HV) and total hand value(THV) were measured and calculated by the KES-F system. The main results are as follows: The values of tensile energy(WT), coefficient of friction(MIU) and geometrical roughness(SMD) were increased by softener but decreased by starch treatment. However, the values of tensile linearity(LT), bending(B, 2HB), thickness(T) and weight(W) were increased by starch but decreased by softener treatment. Tensile resilience(RT) was increased not only by softener but also by starch treatment. It showed that the levels of FUKURAMI, NUMERI and SOFUTOSA were increased by the treatment of softener and the levels of KOSHI and SHARI were increased by the treatment of starch. Total hand value(THV) was lower in fabric with starch treatment than fabric with none treatment.

Although previous studies have emphasized factors affecting people's variety-seeking behavior, research has not been performed to examine the interaction effect of good-bad luck and embodied cognition (hand washing) on variety-seeking behavior. Experience of good and bad luck affects consumer information processing and hand washing is known to reverse the experience of luck. Understanding the interaction effect of good/bad luck and hand washing on variety seeking behavior will shed important light on consumer behavior including choice and product purchase. To do this, a study was performed to investigate the effects of good/bad luck priming and hand washing on variety seeking behavior. Participants were primed with good or bad luck and then were asked to either wash their hands or not. After that, they were led to choose yogurt for the next seven days and the dependent measure was the number of different tastes of yogurt participants picked up. An interaction effect of luck priming and hand washing was found. Results indicate that, in good luck condition, there was no difference in variety seeking behavior between hand washing participants and non-hand washing participants. However, in bad luck condition, hand washing participants chose less diverse tastes of yogurt than non-hand washing participants. Implications of the study findings for the field of consumer psychology and marketing are discussed.

The effect of alkali treatment on the changes in characteristics, mechanical properties, and hand of polyester fabrics was studied. Two kinds of fabrics having different yarn deniers were treated varying weight loss. The results were as follows; 1. Changes in constructional characteristics by alkali treatment were: a decrease in weight & thickness of fabric, a decrease in yarn denier, a decrease in apparent density of fabric, an increase in porosity to air, and a change fiber surface. 2. As for the changes in mechanical properties by alkali treatment, findings were : an increase in WT, RT, MIU, LC, and WC, a decrease in LT, B,2HB, G,2HG,2HGS, MMD, SMD, and RC, ana an increase in drape. 3. Changes in hand by alkali treatment were: a decrease in KOSHI and HARE, an increase in FUUURAMI, SHARI, KISHIMI, and SHENAYAUASA, and an increase in T.H.V 4. In the case of the same weight loss, the hand of 40/24 fabric being composed of thinner yarns was better than the hand of 50/24 fabric. 5. When 50/24 fabric was treated to have the same weight with 40/24 fabric, so the yam deniers of two fabrics were the same, the hand of 50/24 fabric having larger weight loss was better than the hand of 40/24 fabric.

The present study examined how processing features of visual information near the hand would affect task switching. Recent studies reported enhanced cognitive control of visual information presented the near hands. To investigate the enhancement of cognitive control based on the relationship between hand proximity and attention, we implemented 2 experiments. In the task switching performance experiment, the hand proximity effect depended on modality of cue and target. The first experiment showed that stimuli near the hand received greater cognitive control than stimuli far from the hand, resulting in smaller switch cost. The result could rule out the feature-binding problem, which identifies reduced switch cost as the cause instead of hand proximity. Our results show that hand proximity actually reduced switch cost. In the second experiment, we examined the effects of hand nearness, modality, and their interaction on switch cost. In task switching, the target was always visual, and the cue was presented either visually or auditorily. In addition, we manipulated the cue-target interval to observe the preparation effect of cue. The results showed that a visual cue near the hand reduced switch cost by shortening task preparation time. Also, modality switching between an auditory cue and visual target was remarkable in a hand-near condition. The results for the visual cue could be interpreted as a benefit of rapid visual attention orienting. On the other hand, the results for the auditory cue could be interpreted as the cost of interference of modality switching by slower attentional disengagement of stimuli near the hands. Finally, modulation of switch cost by attention induced by hand nearness was discussed.
