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.

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.

최근 고추섭취량과 위암과의 양의상관도를 보이는 역학조사 결과가 발표되었는데 이런 자료를 신뢰하기 위해서는 향신료로 쓰이는 고추의 섭취량이 정확히 측정되어야 할 것이다. 이에 고추의 매운맛 성분 capsaicin의 인체대사산물을 확인하고 이를 응용하여 생리학적으로 의미있는 섭취량을 측정하려는 취지에서 실험을 계획하였다. 먼저 동물실험에서 관찰된 capsaicin의 대사체들을 소변에서 HPLC로 동시에 검출하는 방법을 고안하고 이들 대사체의 신속한 검색을 위해, 이전부터 사용하던 유기용매 추출을 지양하고 효소 glucuronidase 처리한 소변희석액을 바로 HPLC에 주입하는 방법을 사용하였다. 20대의 젊은 여성 5-6명을 대상으로, 이틀 간의 capsaicin 고갈식이 이후 capsaicin이 포함되지 않은 식사시 capsacin의 제공원으로서 고추장을 섭취하게 하였다. 60g씩 사홀 고추장을 섭취한 실험시 여섯명의 참가자 중 네명에게서 섭취를 시작한지 3일 째 4-hydroxy-3-methoxybenzoic acid가, 한 명에게서 3일 째 capsaicin이 검출되었다. 80g씩 나흘을 섭취한 2차 실험시는 세 명의 피실험자에게서 4-hydroxy-3-methoxybenzoic acid가 나흘째 소변에서 검출되었다. 2차 실험에서 나흘째 검출된 4-hydroxy-3-methoxybenzoic acid의 총량은 실험기간 중 섭취한 capsaicinoids 총량의 85% 이상이었다. 따라서 쥐 등을 이용한 capsaicinoid 대사 실험에서는 4-hydroxy-3-methoxybenyl alcohol이 주대사물질이었으나 인체에서는 그와 달리 4-hydroxy-3-methoxybenzoic acid가 주대사산물이라고 여겨진다. 그러나 1, 2차 실험식이를 충실히 따른 두명의 소변에서는 4-hydroxy-3-methoxybenzoic acid를 포함한 어떤 대사체도 찾을 수 없었기 때문에 개인간의 흡수 대사 차이가 크게 기여한다고 추정되며 생리적으로 의미 있는 capsaicin 섭취의 지표 물질은 인체를 대상으로 처음 얻어진 이 결과에 기반으로 한 계속 실험을 통해 선정되리라 기대한다.

The purpose of this study was to call attention to the mental, physical and occupational hazards of the anticancer-drug-handling nurses by examining the possible urinary mutagenicity and measuring physical symptoms and stress level of the nurses exposed to anticancer drugs. The experimental group of the urinary mutagenicity assay was 14 nurses handling anticancer drugs at the medical wards of a hospital located in J city ; the control group was 12 psychiatric nurses of the same hospital. The test material was the nurses' 24hrs urine, which was concentrated by XAD-2 column chromatography. Tester strains were TA98(±S9 mix), TA100(±S9 mix), TA1535(±S9 mix) and TA1537(±S9 mix) ; Salmonella mammalian-microsomal test(Ames test) was employed for the urinary mutagenicity assay. The physical symptoms of which the nurses experienced were investigated through self-reports on open-questionnaires. The stress levels of the experimental group were measured by a stress measuring instrument developed by this author. Reliability of this instrument was found to be adequate (Cronbach's Alpha=0.9079). To ascertain the urinary mutagenicity of the experimental group, the mean and the standard deviation of the colonies of Tester strains appearing on the minimal plates were taken and compared differences between two groups. T-test was employed for the significance test of two groups. The physical symptoms were compared between the two groups through the analysis of the nurse' self-reports. The mean and standard deviation of the stress levels of the experimental group were also calculated and were examined through t-test. The results were summarized as follows : 1. The experimental group revealed significantly higher urinary mutagenicity both in the activation method test and the non-activation method test of the tester strains TA98, TA100 and TA1535. In the case of TA1537, two groups showed no difference in the non-activation method test, but the activation method revealed difference. 2. The physical symptoms were also much more frequently reported in the experimental group. 79.3% of the experimental group reported more than 1 kind of physical symptoms. On the other hand, 33.2% of the control group complained of 1 kind of physical symptom. The items with high symptom frequency were 'headache', 'itching sensation', 'corneal congestion', 'skin allergy' 3. The mean score of stress in the experimental group was 2.41(range 1-4). The experimental group showed the stress level above 2.0 in the 14 of 15 items in all. The highest stress level were recorded in the following items in the order quoted, 'I fear that anticancer drug may touch any part of body while handling it.', 'I feel concerned there is no protective countermeasure against anticancer drug handling.', 'I am afraid the anticancer drug handling may produce a fetal loss in the future'.

Pressure ulcers are serious complications of tissue damage that can develop in patients with diminished pain sensation and diminished mobility. Pressure ulcers can result in irreversible tissue damage caused by ischemia resulting from external loading. There are many intrinsic and extrinsic contributors to the problem, including interface tissue pressure, shear, temperature, moisture, hygiene, nutrition, tissue tolerance, sensory and motor dysfunction, disease and infection, posture, and body support systems. The purposes of this study were to investigate the relationship between buttock interface pressure and seating position, wheelchair propulsion speed. Seated-interface pressure was measured using the Force Sensing Array pressure mapping system. Twenty subjects propelled wheelchair handrim on a motor-driven treadmill at different velocities (40, 60, 80 m/min) and seating position used recline ($100^{\circ}$, $110^{\circ}$, $120^{\circ}$) with a wheelchair simulator. Interface pressure consists of average (mean of the pressure sensor values) and maximum pressure (highest individual sensor value). The results of this study were as follows; No significant correlation in maximum/average pressure was found between a static position and a 40 m/min wheelchair propulsion (p>.05). However, a significant increase in maximum/average pressure were identified between conditions of a static position and 60 m/min, and 80 m/min wheelchair propulsion (p<.05). No significant correlation in maximum pressure were found between a $90^{\circ}$ recline (neutral position) and a $100^{\circ}$, $110^{\circ}$, or $120^{\circ}$ recline of the wheelchair back (p>.05). No significant difference in average pressure was found between conditions of a $90^{\circ}$ recline and both a $100^{\circ}$ and $110^{\circ}$ recline of wheelchair back. However, a significant reduction in average pressure was identified between conditions of a $90^{\circ}$ and $120^{\circ}$ recline of wheelchair back (p<.05). This study has shown some interesting results that reclining the seat by $120^{\circ}$ reduced average interface pressure, including the reduction or prevention in edema. And interface pressure was greater during dynamic wheelchair propulsion compared with static seating. Therefore, the optimal seating position and seating system ought to provide postural control and pressure relief. We need an education on optimal seating position and a suitable propulsion speeds for wheelchair users.

Background & Purpose : Acupuncture with aromatherapy (AA) is a branch of complementary or alternative therapy recently growing in use. As the use of aromatherapy itself has grown so rapidly in recent years, studies about its safety have been accumulating. However, safety of AA has not been studied clinically and the treatment method which has the needles inserted after spreading essential oils exposes the human body more directly to components than aromatherapy. Therefore, we examined the safety of AA on patients treated thereby and physicians practising it. Methods : We observed all inpatients treated with AA from November 21, 2005 to March 31, 2006, in Kyung Hee Oriental Medical Center. During treatment, we monitored all of the newly developed signs from the patients to assess the adverse effects of AA. The patients' and physicians' general characteristics (gender, age, present illness, and treatment days) were obtained from medical records and analyzed to assess the clinical safety of AA in detail. Results : There were 440 patients treated with AA; clinical adverse effects appeared in 3 of them, which can be assessed as 0.7%. The major symptom was chest discomfort and choking originated from smell aversion condition (2 patients), and the other adverse effect was sensation of itching and reddening. However, none of them seemed to have direct relation with AA. A total of eight physicians applied AA and there were no symptoms related to it among them. Conclusions : We suggest that our results will contribute to confirming the safety of AA by offering clinical evidence.
