Objectives: Parkinson's disease (PD) is currently the most rapidly increasing degenerative brain disease due to population aging and westernization of lifestyle. Levodopa is the most commonly used drug to manage PD symptoms. However, levodopa has a problem in that the wearing-off phenomenon occurs as the duration and dose of administration increase. In order to investigate the wearing-off phenomenon in PD patients and devise countermeasures, we conducted a questionnaire survey in Korea. Methods: For the study, a questionnaire with a total of seven items was prepared. Part IV of the MDS-UPDRS (Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale) and the WOQ-9 (9-symptom Wearing-off Questionnaire) were used as references. Results: Of the 48 patients who completed the questionnaire, all 47 patients who completed the questionnaire experienced the wearing-off phenomenon. Only one of the patients diagnosed with PD a year ago did not experience the wearing-off phenomenon. Patients frequently mentioned a lack of sleep and stress as aggravating factors for wearing-off. They also stated that in order to resolve the off-state, they walked, massaged, warmed up the body, stretched and exercised. Conclusions: Because wearing-off is such a common occurrence, it is thought necessary to develop wearing-off prevention and resolution measures that PD patients can use in their daily lives.

A 69-year-old female diagnosed with idiopathic Parkinson's disease and treated with anti-Parkinsonian medications, including levodopa, for 7 years presented with complaints of wearing-off phenomenon and delayed onset of medication efficacy, resulting in postural instability and feeling of severe exhaustion. The patient underwent a 50-day course of treatment with Bonoesikpungjigyeong-tang formula. The effects of the treatment were evaluated by recording the average time to onset of medication efficacy, the average time to medication wearing-off, and discomfort due to wearing-off phenomenon. Postural instability was assessed using the Numeric Rating Scale (NRS). The patient's overall quality of life was assessed using the EQ-5D-3L. After 50 days of treatment, the average time to onset of medication efficacy decreased, and the average time to medication wearing-off increased. Discomfort due to wearing-off phenomenon and postural instability decreased. This case suggests that Bonoesikpungjigyeong-tang might be an alternative for improving discomfort caused by long-term levodopa intake.

The knitting method of the sleeves for improving movement adaptability were studied in this paper. The purpose of this study is proposing a knitting method that is suitable for the bodies of women in their 20's and can enhance wearing satisfaction. To see the effect of the bind-off length at the axilla, a movement adaptability test was undertaken for 4 samples that have bind-off at bodices. In addition to that, the analysis of their sliding distance with respect to the human motions were executed. The results of this study were listed below. Its result was that the samples with small bind-off lengths represent better wearing satisfaction than the samples which have large bind-off lengths. The comparison of the sliding distances at the hem, waist and sleeves with respect to the tester's motions also shows that the sample having small bind-off makes better result than the sample with large bind-off. It was observed that the optimal length of bind-off was 2cm for the improvement of the sleeve functionality.

This study was performed to analyze the wearing practice and the purchasing characteristics of brassieres in order to offer basic data to produce superior brassiere and to improve the wearing comfort. The questionnaire were 146 Korean college female students. For data analysis, descriptive analysis, crosstabs, factor analysis and one-way ANOVA were used. The results were as follows, first, most subjects didn't know the sizing system of brassiere and their own breast size. So the degree of satisfaction of wearing brassiere was low than subjects who knew their own breast size. And they replied that the most unsatisfaction factor was brassiere size. Second, when subjects decided to purchase a brassiere they considered size, design, color, cost, fabric and brand and so on. Among them size and design were considered the most important. Third, the subjects who wear brassiere all day long, they considered wearing comfort and cost rather than design and collar. Therefore, the markets with brassieres would be able to segmented based on consumers' characteristics. Firth, the subjects were dissatisified at size, the taking off wire and shape modification after washing. And they requested the development of various size, fabric and cost improvement and fittness of brassieres. These results imply that to improve the wearing comfort of brassiere, it is so important to produce and develop various types of size first of all. And consumers should know size system of brassiere and their own breast size.

In this study, girdle wearing was surveyed on the female college students in Seoul and Seoul satellite cities. Data were collected by convenient sampling method, and sample size was 252 subjects in 18 to 29 years. Questionnaire was composed of 5 parts: experience of girdle wearing, the preference of girdle type, degree of dissatisfaction/discomfort in wearing girdle, wear sensation evaluation of girdle fabrics, including demographic and anthropometric data. The results of surveys are as follows: Experience of girdle wearing (season of wearing girdle, main intention of wearing girdle, frequency of wearing, body part to want to be shaped by girdle) was examined. Especially body parts to be shaped by girdle were in order of abdomen > hip > thigh > waist-hip sideline. Therefore, it would be considered that female college students want to care about the shape of abdomen or hip. The long leg panty type was most preferred among the girdle types. The reason of preference of long leg panty type was cost > easiness of putting on-and-off > shaping many body parts at once. For dissatisfaction/discomfort in wearing the commercial girdles, it showed in order of poor ventilation at sweating > static electricity with outer garment > difficult breathing due to pressure > deformation after laundering.

This study was conducted to analyze the wearing practice and the purchasing characteristics of household rubber gloves in order to obtain the product demands for quality improvement. The effects of wearing time per day and demographic characteristics on those were evaluated. A questionnaire was developed and administered to 494 housewives. Statistical tests such as descriptive analysis, crosstabs, factor analysis, one-way ANOVA, were used to analyze the data. The results indicated that housewives were largely divided into two groups according to the wearing time per day. One group wore gloves more than 3 hours a day, while the other wore less than 3 hours. We found that there were significant differences in the wearing practice and the purchasing characteristics between these two groups. It showed that the quality improvement of household rubber gloves should be achieved in a point of view of the comfort feeling and easiness in wearing and taking off. The housewives showed positive attitude toward pliability and necessity, while negative altitude toward dryness, comfort and mobility in wearing. The household rubber gloves were identified as the necessities which is so familiar and common that only a few of demographic characteristics have effect on.

Objective: The use of chemicals for building prosthetic sockets present the possibility of being hazardous and unsafe due to off-gassing. The purpose of the present study was to investigate if freshly made materials used in prosthetic sockets causes off-gassing that would penetrate the skin and cause damage to the kidneys or blood. Design: Cross-sectional study. Methods: In this research, the off-gassing effects during the initial curing process of styrene monomer, vinyl ester resin, epoxy methacrylate resin, benzene-1, 3-dimethaneamine, trimethylhexanedlamine, and paratertiarybutylphenol were analyzed. Acid detection strips were placed inside newly fabricated mock-prosthetic sockets and left overnight in a closed environment to find out if acid was present in the invisible fumes. The plastic was worn by 9 subjects and urinalysis was made after 48 hours to test for any kidney or blood toxicity of the resins. Results: After wearing the plastic cuff for 48 hours, the ratio of protein to creatinine in the urine was raised to an abnormal level in five out of nine subjects. Four out of the nine subjects showed normal protein to creatinine ratios after wearing the device. The results showed that damage to the kidney occurred from wearing the resins after curing in half of the subjects. Conclusions: It is very important to conduct patient intakes which includes the assessment of renal function. Off-gassing in vented chambers may be needed to protect both prosthetists and patients.

Ankle-foot orthosis with an artificial pneumatic muscle which is intended for the assistance of plantarfelxion torque was developed. In this study, power pattern of the device in the various pneumatics and the effectiveness of the system were investigated. The pneumatic power was provided by ankle-foot orthosis controlled by user‘s physiological signal, that is, muscular stiffness in soleus muscle. This pneumatic power can assist plantarflexion torque of ankle joint. The subjects performed maximal voluntary isokinetic plantarflexion motion on a biodexdynamometer in different pneumatics, and they completed three conditions: 1) without wearing the orthosis, 2) wearing the orthosis with artificial muscles turned off, 3) wearing the orthosis activated under muscular stiffness control. Through these experiments, we confirmed the effectiveness of the orthosis and muscular stiffness control using the analyzing isokinetic plantarflexion torque. The experimental results showed that isokinetic torques of plantarflexion motion of the ankle joints gradually increased in incremental pneumatic. The effectiveness of the orthosis was -7.26% and the effectiveness of the muscular stiffness control was 17.83% in normalized isokinetic plantarflexion torque. Subjects generated the less isokinetic torques of the ankle joints in wearing the orthosis with artificial muscles turned off, but isokinetic torques were appropriately reinforced in condition of wearing the orthosis activated under muscular stiffness control(17.83%) compared to wearing the orthosis(-7.26%). Therefore, we respect that developed powered orthosis is applied in the elderly that has weak muscular power as the rehabilitation equipment.
