  • Purpose: The purpose of this study was to investigate the possibility that a dynamic facial composite flap with sensory and motor nerves could be made available from donor facial composite tissue. Methods: The faces of 3 human cadavers were dissected. The authors studied the donor faces to assess which facial composite model would be most practicable. A "panorama facial flap" was excised from each facial skeleton with circumferential incision of the oral mucosa, lower conjunctiva and endonasal mucosa. In addition, the authors measured the available length of the arterial and venous pedicles, and the sensory nerves. In the recipient, the authors evaluated the time required to anastomose the vessels and nerve coaptations, anchor stitches for donor flaps, and skin stitches for closure. Results: In the panorama facial flap, the available anastomosing vessels were the facial artery and vein. The sensory nerves that required anastomoses were the infraorbital nerve and inferior alveolar nerve. The motor nerve requiring anstomoses was the facial nerve. The vascular pedicle of the panorama facial flap is the facial artery and vein. The longest length was 78 mm and 48 mm respectively. Sensation of the donor facial composite is supplied by the infraorbital nerve and inferior alveolar nerve. Motion of the facial composite is supplied by the facial nerve. Some branches of the facial nerve can be anastomosed, if necessary. Conclusion: The most practical facial composite flap would be a mid and lower face flap, and we proposed a panorama facial flap that is designed to incorporate the mid and lower facial skin with and the unique tissue of the lip. The panorama facial composite flap could be considered as one of the practicable basic models for facial allotransplantation.

  • This study analyzed clothing pressure, blood flow, and subjective sensations among women in their 50s and 60s while wearing commercially available yoga bra tops (YBTs). These findings could then serve as basic data for designing YBT for women in this age range. Clothing pressure and blood flow reactions were measured in seven participants wearing four commercially available YBTs. Subjective sensations of pressure and comfort were also evaluated. The calculated data were analyzed using the SPSS 24.0 statistical program. The results suggested that YBT4 exerted the lowest clothing pressure, while YBT2 and YBT3 exerted relatively higher clothing pressures. Participants' blood flow decreased while wearing YBTs compared to the control garment. The decrease of 47.3% when the participants wore YBT2 was especially significant. The results confirmed that the blood velocity rate was physiologically lower while wearing all four YBTs than when wearing the control garment. Results for subjective pressure and overall comfort confirmed that YBT2 and YBT3 exerted relatively high pressure, while YBT4 did not exert pressure.

  • To enhance the design and comfort of waist-protection corsets, this study analyzed the product characteristics of five types of posture-correction corsets that are available commercially. Additionally, subjective evaluation of the corsets was conducted on women aged 20 to 60 years, in terms of design, material preference, fit, comfort, degree of correction, freedom of movement, tightness, and convenience of front fastening. Following product analysis, the five corset types were divided into: two soft, one semi-hard, and two hard types in terms of the degree of elongation. As a result of pattern analysis, the soft type was designed to improve fit by reflecting the body curvature, whereas the semi-hard and hard types were relatively flat. Through the wearing sensation assessment, the hard type manufactured by company S was the best in terms of design, material, fit, comfort, correction degree, and freedom of movement. The soft type was average in design, material, and fit while relatively poor in the correction degree and tightness. The results indicated that soft materials, flexible bones with appropriate tension, patterns designed to snugly fit the body with large curvature at the top and bottom for better inflection, and adjustable support belts that can be double-fixed are crucial elements in improving the corset design to boost the comfort of wearing. These study results are helpful in the development of waist-protection corsets with excellent wearing comfort and design appreciated by customers.

  • The hospital situation, timing, and patient restrictions have become obstacles to an optimum therapy session. The crowdedness of the hospital might lead to a tight schedule and a shorter period of therapy. This condition might strike a post-stroke patient in a dilemma where they need regular treatment to recover their nervous system. In this work, we propose an in-house and uncomplex serious game system that can be used for physical therapy. The Kinect camera is used to capture the depth image stream of a human skeleton. Afterwards, the user might use their hand gesture to control the game. Voice recognition is deployed to ease them with play. Users must complete the given challenge to obtain a more significant outcome from this therapy system. Subjects will use their upper limb and hands to capture the 3D objects with different speeds and positions. The more substantial challenge, speed, and location will be increased and random. Each delegated entity will raise the scores. Afterwards, the scores will be further evaluated to correlate with therapy progress. Users are delighted with the system and eager to use it as their daily exercise. The experimental studies show a comparison between score and difficulty that represent characteristics of user and game. Users tend to quickly adapt to easy and medium levels, while high level requires better focus and proper synchronization between hand and eye to capture the 3D objects. The statistical analysis with a confidence rate(α:0.05) of the usability test shows that the proposed gaming is accessible, even without specialized training. It is not only for therapy but also for fitness because it can be used for body exercise. The result of the experiment is very satisfying. Most users enjoy and familiarize themselves quickly. The evaluation study demonstrates user satisfaction and perception during testing. Future work of the proposed serious game might involve haptic devices to stimulate their physical sensation.

  • The purposes of this study were to investigate problems related to quality of life and to identify residents needs for the university educational program for the community residents. The data were analyzed by using $x^2$-test, F-test and multiple range test. Findings of this study provided some useful implications to develop educational programs for community people. These implications are as follows. In the aspect of home management, the need for education about time management was relatively high and the degree of time conflicts was varied to family size, educational level of house, housewife's employment status and outside work time. In the program area of economic life, education for enhancing ability to cope with unexpected events and impulsive consumption behavior, and education for money management technique and value clarification should be included. There were significant differences in the parents' role difficulties according to mother's age and income. Especially parents' role difficulties were children's social emotional development and educational activity. The major problems in management of clothing and textile products were the change of textile sensation, the poor quality of necessaries, and discoloration. This result suggests that education programs on management of clothing and textiles should be developed. In health and food management it showed that subjects were afraid of cancer, hypertension, cerebral vascular diseases in relation with food habits. Hence program of education for health and good food habits should be developed.

  • The process of making fashion accessories brings many benefits to visually impaired people. It helps the development of their tactile sensation, improves their aesthetic attitude, creativity, and imagination, and brings energy to their life. The current accessory making education in Korea is targeted to people with normal vision, and does not reflect the specific needs of the visually impaired. This causes a lot of trouble in educating the visually impaired. Therefore, this study aims to increase the efficiency of accessory making education by selecting curriculum and material that are appropriate and systematic for the visually impaired. In order to understand visual impairment, literature review was conducted to examine the definition and classifications of the impairment. Research was also done regarding material types and production method of fashion accessory. The study also designed an education program, including teaching guidelines, by referring to literature related to fashion accessory design, teaching guideline. The study conducted 12 experiments based on the results from April to June 2014. After revising and supplementing the teaching method, 2nd set of experiments were conducted from July to September 2014. Each class lasted for one and a half hour every week, and the class was composed of 6 students, 1 instructor and 1 volunteer. After each class, interviews were done to collect student opinions about the curriculum and material. Total experiment results and interview were reflected in constructing the final education program. The result of the experiments and interviews showed that selecting the accessory materials for class must be selected carefully. The visually-impaired students were very sensitive to the size, texture, shape, hole size of beads and length of material. After the experiments, all the students were able to distinguish the size and shape of the beads well, and finished the accessories using the given materials. The study verified that there is a need for another approach when educating the visually impaired about fashion accessory design. Many factors need to be considered from selecting materials to class contents. This study will contribute as a reference to fashion accessory making education as well as other design education for the visually impaired.

  • This study was conducted to evaluate the differences in external appearances and functional qualities between the slacks which were patterned on existing designs and on a new design in order to improve on their level of comfort of ready-made clothes for abdominally fat women. Five abdominally fat women in their 60's were chosen as experimental participants. Twenty-four external evaluation items, and seven different actions involving six moving parts of the body were investigated with a 5-level scale in the repeated wearing test. The results were analyzed by statistical methods. The newly designed pattern in this study was definitely superior to the other two patterns(L-type and K-type) on the external appearance evaluation. The newly pattern removed a waist belt and a dart from the front part of the garment and gave surplus space around the waist. It prevented superfluous wrinkles at the abdominal region and thighs. The superfluous wrinkles at the side regions also disappeared due to the length (inseam) reduction from waist to crotch. The newly pattern made the center-line of the back side slightly sloped to the main pattern in order to remove the drooped line. The newly pattern showed the highest score in the functional test of several actions. It was due to the reduction of the length from waist to crotch as well as the belt width. It made waist-line movement better, and made it easier and more comfortable to sit down. The newly pattern also showed the highest score in the functional test classified by specific movements of parts of the body for the same purpose. The slacks which were made of elastic materials showed better results than the non-elastic ones on external appearances and functional test items. It showed that the elastic materials played a better role in the increase of functional action of abdominally fat, aged women. This study suggests that the newly designed slacks pattern could give abdominally fat, aged women better external features and a more comfortable fitting sensation. As well, the results were significant as basic data to produce ready-made and/or tailer-made garments.
