This study aims to propose various ways to utilize CLO, which focuses mainly on the production of 3D virtual samples, by comparing it with the pattern drafting functions of Four apparel CAD experts, who have teaching experience in YUKA and CLO, participated in a focus group interview, and a basic bodice prototype drafting was carried out by each participant to evaluate the pattern drafting functions of YUKA and CLO. The result of this study showed that the pattern drafting tools of YUKA are subdivided since YUKA is a CAD tool inherently specialized in pattern making. Though CLO provided a relatively limited pattern drafting menu compared to YUKA, it was found that pattern drafting could be accomplished with the help of supplementary tools and functions. This finding suggests that each CAD offers the corresponding tools for the same use of menus or functions in the prototype drafting process. The major difference between YUKA and CLO is that YUKA defines the pattern area by a set of line segments, whereas CLO utilizes an outline composed of closed curves. YUKA provides various specific tools according to the options such as angles, straight lines, and curves, while CLO produces the same results using combinations of a limited number of tools. Compared with YUKA, the advantage of CLO is its user-friendly task environment such as the Windows-based user interface, from the usability perspective. This study concludes that pattern drafting education using CLO would help not only industrial 3D design practitioners but also pattern education in academia
Purpose : This study was to investigate the change of accommodative functions by different color density and color of colored lenses. Methods : Participant had a normal NPC and no dyschromatopsia, phoria and eye disease, also had no histories of eye surgery in 31 students of university. Their accommodative functions were measured according to 50%, 80% density of the gray, blue, brown lens and non-colored lenses. Tests of accommodative functions performed include amplitude of accommodation, accommodative facility, relative accommodation, and accommodative lag. Results : The amplitude of accommodation and accommodation lag were increased when wearing the colored lens. Negative relative accommodation was more increased when wearing the colored lens than achromatic. Positive relative accommodation increased when wearing the blue color lens density by 50%. Also, accommodation facility increased when wearing the colored lens, but, as the density of the color increased, the accommodation facility was decreased. Conclusion : As since the accommodation function changes according to density of the colored lenses, working distance and environment of the wearing colored lens should be considered when selecting density and color of colored lenses.
Objective: The purpose of this study was to investigate the effect of robot arm reach training on upper extremity functional movement in chronic stroke survivors. Design: One group pretest-posttest design. Methods: Thirteen chronic stroke survivors participated in this study. Robot arm reach training was performed with a Whole Arm Manipulator (WAM) and a 120-inch projective display to provide visual and auditory feedback. During the robotic arm reach training, WAM provided gravity compensation and assist-as-needed (AAN) force according to the robot control mode. When a participant could not move the arm toward the target for more than 2 seconds, WAM provided AAN force to reach the desired targets. All patients participated in the training for 40 minutes per day, 3 times a week, for 4 weeks. Main outcome measures were the Fugl-Meyer Assessment (FMA), Action Research Arm Test (ARAT) and Box and Block Test (BBT) to assess upper extremity functional movement. Results: After 4 weeks, significant improvement was observed in upper extremity functional movement (FMA: 42.15 to 46.23, BBT: 12.23 to 14.00, p<0.05). In the subscore analysis of the FMA upper extremity motor function domains, significant improvement was observed in upper extremity and coordination/speed units (p<0.05). However, there were no significant differences in the ARAT. Conclusions: This study showed the positive effects of robot arm reach training on upper extremity functional movement in chronic stroke survivors. In particular, we confirmed that robot arm reach training could have a positive influence by leading to improvement of motor recovery of the proximal upper extremity.

Background: The purpose of this study was to develop a sit-to-stand transfer assistive device, and to conduct a feasibility test. Design: A technical note. Methods and results: In this study, we developed a sit-to-stand transfer assistive device for the elderly and the disabled who have difficulty standing up independently from sitting positions. The sit-to-stand transfer assistive device allows the user to transfer the weight from a sitting position to a standing position while shifting the weight forward by grabbing and pulling a support stand. Ten healthy adults participated in the feasibility test of the device. Each participant used the developed sit-to-stand transfer assistive device and investigated supplementation through a brief interview. As a result of the feasibility test, the opinion was that the device could assist the sit-to-stand transfer to some extent. There were opinions that it needed a function to adjust the height of the knee protective plate in the sitting position according to the user's physical characteristics. Because of the inconvenience of operating the lock device for fixing the position and adjusting inclination, there was an opinion that the improvement for a locking device is needed. There were opinions that it would be better to reduce the size of the device due to its inconvenience of portability. Conclusion: In this study, we developed the sit-to-stand transfer assistive device for the elderly and the disabled who have difficulty standing up independently from sitting positions. In addition, it is considered that the upgrade of the device is necessary for the future since there are supplementary opinions on some points.
Background: In the present study, the age- and sex-adjusted Constant score (CS) in a normal Indian population was calculated and any differences with other population cohorts assessed. Methods: The study participants were patients who visited the outpatient department for problems other than shoulder and healthy volunteers from the local population. Patients without shoulder pain/discomfort during activity were included in the study. Subjects with any problem that might affect shoulder function (e.g., cervical, thoracic spine, rib cage deformity, inflammatory arthritis) were excluded. Constant scoring of all participants was performed by trained senior residents under the supervision of the senior faculty. Shoulder range of movement and strength were measured following recommendations given by the research and Development Committee of the European Society for Shoulder and Elbow Surgery (2008). A fixed spring balance was used for strength measurement; one end was fixed on the floor and the other end tied with a strap to the wrist of the participant, arm in 90° abduction in scapular plane with palm facing down. Results: Among the 248 subjects (496 shoulders), the average age was 37 years (range, 18-78 years), 65.7% were males (326 shoulders) and 34.3% females (170 shoulders). The mean CS was 84.6±2.9 (males, 86.1±3.0; females, 81.8±2.9). CS decreased significantly after 50 years of age in males and 40 years of age in females (p<0.05). The mean CS was lower than in previous studies for both males and females. Heavy occupation workers had higher mean CS (p<0.05). A linear standardized equation was estimated for calculating the adjusted CS for any age. Conclusions: Mean CS and its change with age differed from previous studies among various population cohorts.
Purpose: The purpose of this study is to develop a reproducible and reliable method for evaluating the masseter's functional state by measuring the masseter muscle with ultrasonography (US). Methods: Nineteen healthy adults (9 males, 10 females) were the subjects of this study. During US scanning, the image was taken from the thickest part of the masseter muscle in the image. To evaluate changes in thickness during masseter function, US images were taken of the participant's masseter muscle at rest and during clenching. In this study, US scanning was conducted using two approaches to compare the difference in masseter muscle thickness determined when inducing maximum bite force (MBF). Results: All 19 subjects completed US scanning of the masseter muscle at rest and during clenching under the conventional method and the articulation paper method. There was no difference in masseter muscle thickness measured at rest. However, the thickness of the masseter muscles determined by the articulation paper during jaw clenching was greater than that measured by the conventional method. Conclusions: In conclusion, using the US for masseter muscle evaluation can offer objective and functional information on the masseter muscle. A standardized US scanning method needs to be developed to obtain reproducible and reliable information on the masseter muscle at rest and during clenching. In particular, generating MBF using an articulation paper can be a reproducible and reliable method of measuring the functional state of the masseter muscle.

Background: Long working hours causes several health risks, but little is known about its effects on the liver. This study aimed to examine the correlation between working hours and abnormal liver enzyme levels. Methods: We used data from the Korea National Health and Nutrition Examination Survey IV-VII. For the final 15,316 study participant, the information on working hours was obtained through questionnaires, and liver enzyme levels, consisting of serum levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT), through blood tests. The relationship between weekly working hours and abnormal levels of liver enzymes was analyzed using multiple logistic regression, and a trend test was also conducted. Results: In male, working ≥ 61 hours per week was significantly associated with elevated AST and ALT levels compared with working 35-52 hours per week. Even after adjusting for covariates, the odds ratios (ORs) of abnormal AST and ALT increased by 1.51 (95% confidence interval: 1.20-2.05) and 1.25 (1.03-1.52), respectively, and a dose-response relationship was observed. This association was more prominent among the high-risk group, such as those aged > 40 years, obese individuals, worker on non-standard work schedule, pink-collar workers, or temporary worker. No correlation was observed in female. Conclusions: Long working hours are associated with abnormal liver function test results in male. Strict adherence to statutory working hours is necessary to protect workers' liver health.

Objective : The purpose of this study is investigate the effects of sensory integration combined with auditory treatment on the sensory processing, visual perception and attention ability of children with developmental delay. Methods : A combined treatment of auditory training and sensory integration therapy was implemented to 3 children aged 4 to 7 and diagnosed with developmental delay during 9 weeks period from December 2016 to January 2017. ABA' design which is one of single subject research designs was used in this study. Baseline A had 4 sessions, intervention B had 15 sessions, and baseline A' had 4 sessions, so 23 sessions were applied in total. During the baseline A and A 'periods, visual perception ability was measured by K-DTVP-2 (Korea Developmental Test Visual Perception-2) and sensory processing ability was evaluated by sensory profile. The maintenance time of attention was measured with the absence of intervention for the baseline period, and for the intervention period, it was measured at 10 minutes break time which was provided after the intervention. The children's attention time during a fine motor task provided were measured using video recorder with the interval recording method, and the interval for the evaluation was 30 seconds. Results : No statistically significant difference were found in the visual perception function and sensory processing scores before and after treatment. Attention of participant A enhanced significantly while that of participant B and C did not improve significantly. Conclusion : It is hard to conclude that sensory integration therapy combined with auditory perception training has positive effects on visual perception function and attention of children with developmental delays. However, there were significant increase in attention and improvements in behavior related to sensory processing for some cases in this study. In further study, longer intervention periods and valid measurement need to be applied in order to get better results. And it is proposed that more studies need to be done to enhance evidence of auditory perception training as a mean to facilitate attention and to prepare learning.
'Saiee', which could mean between, intra- and inter-, is a crucial topic in theatre as theatre has tension between actor and audience, reality and illusion, and everyday life and extraordinary life. Especially, it is interesting that the function of 'Saiee' is connected to extension and application of drama and theatre such as educational theatre, dramatherapy and applied drama/theatre. Such works are expected to educational or therapeutic effects, thus concern and support, demand and supply of these works is getting increased. However, it is true that researches on spirit, aesthetic and direction of these works are not sufficient, compared to quantitative increase and diversity. This study will explore Boal's Theatre of the Oppressed(TO from the below), which is key theory and technique of applied drama/theatre field with viewpoint of 'Saiee' theatre to look at spirit, aesthetic and direction of this field. Saiee's energy could observe the object with distance(distance), form the relationship with that object(inter) and create new circumstance through that relationship(intra). And Boal's TO tried to Saiee's theatre by using Saiee's dynamics variously. It bases on the phenomenon of metaxis. Boal's TO believes that drama/theatre is unique nature and ability of human being, that is to say, it is based on Homo Theatrum, human plays and does theatre. Therefore, the participant of Boal's TO is extended to everyone in everyday life. This activity is not only individual work to find his/her identity but also solidarity and possibility to change society which they belong to. It is the dynamics of 'Saiee' to make this possible. Boal's TO thinks that relationship and balance between individuality and sociality is important. The way of conversation in Boal's TO includes questioning, listening and communication. Unfamiliarity or distance of 'Saiee' makes interest in other people and question about them. Questioning through theatre and concern on other beings to search for the answer (this is listening), would be new relationship(and possibility) to extend him/herself. The communication and relationship leads to possibility and ability to create another world. This is the function of 'inter-' and 'intra-' in theatre of 'Saiee'. Lastly, it is various that Boal's TO as 'Saiee' theatre uses the dynamics of 'Saiee'. The diversity of technique comes from the application to humans in every moment and every time. To apply 'Saiee's aesthetic actively, concern and research on people 'now and here' should be proceed.
Objectives : This study aimed to investigate the effect of beat-keeping games in smartphone applications on improving executive functions in children with developmental delays. Methods : Three children diagnosed with developmental delay were included in this study. The ABA design used a single-subject experimental research design. The independent variable was the beat-keeping game. The game was held three times a week for a total of seven times for 20 minutes, including breaks. The dependent variable, "Visual-motor speed," was measured every session to assess if the beat-keeping game was effective in improving the participant's executive function. Further, before and after the intervention, "Children's Color Trails Test (CCTT)", "Block design," and "Finding hidden picture" were measured. Results : All three participants showed improvement in the performance of the beat-keeping game and the executive functions of "Visual-motor speed" and visual attention. Conclusions : Based on the results of this study, various effective applications for learning and intervention can be developed and applied to children with developmental delays who have difficulty in motivating themselves and lack attention.
