  • This correlational descriptive study sought to define the relationship between the experience of Sanhujori, Korean tradition non-professional postpartal care after delivery and abortion and present physical symptom distress of arthritis female who visited to outpatient clinic of rheumatic internal medicine at three hospital located in Seoul, Pusan, Chongju, Korea. Data from a convenience sample of 98 women who orally agreed to be respondent were collected from September 1, 1998 to October 31, 1998 for two months by way of interview with semi-structured questionnaire. Data analysis consisted of frequency, percentage, mean, S. D., Pearson Correlation Coefficient, t-test, ANOVA and Scheffe test as a post hoc by SPSS. The results of the study were as follows ; Mean age of participants as 52.8 years and mean number of children 3.3. Mean frequency of child birth was 3.1 times per woman, 67.4% of respondents had menopause, 57.0% did not have Sunhujori after abortion. The health status implies the subjective health status women perceived, which came from the three points of view of the present, comparative with other of same age and changed after delivery. The respondents of 76.1% perceived them as unhealthy and the main sites of physical symptom distress were upper & lower extremities including knee and hand 34.8%, shoulder 26.5%, waist 22.4%. Women perceived the etiology of the arthritis as 'did Sanhujori wrongly' 36.7%, 'aging process' 24.5%, 'stress' 16.3%, 'overwork' 15.3%, 'Immunocompromize' & 'physical constitution' 7.1% respectively, 'character' 3.1%, 'genetic' 2.0%, 'malnutrition' 1.0%. The mean period of Sanhujori after delivery was 20.4 at the first child and 18.1 at the second child. The higher frequency of child birth, the shorter period of Sanhujori. For the subjective evaluation of whether the women did Sanhujori well or not, the rate of 'did Sanhujori well' was the highest rank in the first child and the rate of 'did not particularly Sanhujori well' was the highest rank in the last child. There was a significant positive correlation between physical function disability and rheumatoid arthritis symptom at the level of 1% of significance statistically(r=.406). And a positive correlation between physical function disability and Sanhubyung symptom at the level of 5% of significance statistically(r=.224). There was a significant positive correlation among rheumatoid arthritis symptom, Sanhubyung symptom and menopause symptom at the level of 1%-5% of significance statistically. Most of all, the correlation between Sanhubyung symptom and menopause symptom was the higher than others. There was a negative correlation between the present physical symptom distress and experience of Sanhujori(r=.-130), however it was not significant statistically. However, there was a positive correlation between subjective health status and experience of Sanhujori at the level of 1% of significance statistically(r=.328). In conclusion, this finding reconfirmed the positive relationship between the perceived health status and experience of Sanhujori after delivery among women of arthritis. It provides a challenge to the professional care givers to study further on the effects of Sanhuiori after abortion or delivery on the physical symptom distress from the variouis aspects through the cross-sectional and longitudinal research. The strategy for the development of the appropriate intervention for primary prevention of sequele after childbirth and quality of care for desirable health outcomes for postpartal women with considering deeply on the relationship between women's health and postapartal care.

  • This study investigated the recognition and preference of a chicken menu according to the age of adults in the Jeonbuk area. Self-administered questionnaires were collected from 394 adults (male 55.3%, female 44.7%) residing in the Jeonbuk area. Descriptive and comparative statistical data analysis was completed using SPSS v. 12.0. The frequency of consumption of chicken-containing foods for the younger group (20~30 years old) was significantly higher than the frequency of older groups (over 40) (p<0.001). The younger group also consumed chicken food through a delivery service, whereas the older group consumed chicken through delivery and self-cooking. Approximately 50.0% of the older group preferred the chicken leg whereas 38.1% of the younger group preferred the chicken breast (p<0.001). The most highly recognized chicken menu items, among 36 chicken menus, were Samgyetang (2.93), chicken dori-tang (2.93), and fried chicken (2.93). The older group knew about a chicken menu made by traditional cooking much more than the younger group. The most highly preferred chicken menu item was spicy fried chicken (4.18). The preference for Western-style chicken menu (e.g. Cajun chicken salad, chicken sandwich) was significantly higher in the younger group than the older group (p<0.001, p<0.05). Therefore, to develop a new chicken menu, the consideration of favorite chicken parts and an age-based menu is necessary.

  • To investigate the permeability of lidocaine, percutaneous absorption studies were performed using excised hairless mouse skin and the penetration of lidocaine via the skin was determined. To increase the skin permeation of lidocine, the effects of $Labrasol^{(R)}$, $Labrafil^{(R)}$, $Labrafac^{(R)}$ and $Transcutol^{(R)}$ were investigated. The skin permeation of lidocaine was increased when $Labrasol^{(R)}$ and $Transcutol^{(R)}$ were used as permeation enhancer. To evaluate the influence of ultrasound, various factors such as application modes (continuous mode and pulsed mode), frequency (1.0 and 3.0 MHz) and intensity (1.0, 1.5 and 2.0 w/$cm^2$) were investigated with lidocaine hydrogel. The pronounced effect of ultrasound on the skin permeation of lidocaine was observed at all ultrasound energy levels. The influence of frequency having an effect on skin permeation rate was higher in the case of using 1 MHz, 2.0 w/$cm^2$ and continuous treatment. As the intensity of ultrasound increased, the permeation of lidocaine was accelerated. The in vivo anesthetic effects were evaluated by two aspects as mechanical threshold and electrical threshold. Six healthy volunteers consented to the randomized, double-blind, and cross-over designed study in each group. In each subject, 3 groups were adapted such as K group (ultrasound with gel base only), L group (lidocaine gel) and B group (ultrasound with lidocaine gel). In conclusion, lidocaine was potent anesthetic which could be block pain threshold effectively. And ultrasound could accelerate the skin penetration of lidocaine. The phonophoretic delivery system could be a good candidate for lidocaine as a local anaesthetic to improve the skin permeation and in vivo anaesthetic effect.

  • In order to thoroughly analyze risk factors of breast cancer (BC) in premenopausal Uruguayan women, a case-control study was carried out at the Pereira Rossell Women's Hospital, Montevideo, where 253 incident BC cases and 497 frequency-matched healthy controls were interviewed on menstrual and reproductive story, were administered a short food frequency questionnaire and undertook a series of body measurements necessary to calculate body composition and somatotype. Odds ratio (OR) coefficients were taken as estimates of relative risk derived from unconditional logistic regression. Among the classical risk factors, only the family history of BC in first degree relatives was significantly associated with risk of premenopausal BC (OR=2.20, 95% CI 1.33-3.62). Interestingly, this risk factor was found to be stronger in women of ages >40 (OR=4.05, 95% CI 2.10-7.81), late menarche (OR= 2.39, 95% CI 1.18-4.85), early age for their first delivery (OR=3.02, 95% CI 1.26-7.22), short time between menarche and first delivery (OR=3.22, 95% CI 1.29-8.07), and with high parity (OR=4.10, 95% CI 1.79-9.36), although heterogeneity was detected only for age and parity. High consumption of red meat was positively associated with the disease risk (OR=2.20, 95% CI 1.35-3.60), in the same way as fried foods (OR=1.79, 95% CI 1.12-2.84). Conversely, a high intake of plant foods displayed a protective effect (OR=0.41, 95% CI 0.26-0.65). Except for hypertension (OR=1.55, 95% CI 1.03-2.35), none of the analyzed components of metabolic syndrome were associated to BC risk. Particular increases of risk for premenopausal BC were found for family history in first degree relatives in certain subsets derived from the menstrual-reproductive history. Preventive strategies could broaden their scope if new studies confirm the present results, in view of the limited prevention measures that premenopausal BC currently has.

  • As the aged population grows around the world, many medical instruments and devices have been developed recently. Among the devices, a drug delivery stent is a medical device which requires precision machining. Conventional drug delivery stent has problems of residual polymer and decoating because the drug is coated on the surface of stent with the polymer. If the drug is impregnated in micro hole array on the surface of the stent, the problem can be solved. Micro sized holes are generally fabricated by laser machining; however, the fabricated holes do not have an enough aspect ratio to contain the drug or a good surface finish to deliver it to blood vessel tissue. To overcome these problems, we propose a vibration-assisted machining mechanism with PZT (Piezoelectric Transducers) for the fabrication of micro sized holes. If the mechanism vibrates the eyepiece of the laser machining head, the laser spot on the workpiece will vibrate vertically because objective lens in the eyepiece shakes by the mechanism's vibration. According to the former researches, the vibrating frequency over 20kHz and amplitude over 500nm are preferable. The vibration mechanism has cylindrical guide, hollowed PZT and supports. In the cylinder, the eyepiece is mounted. The cylindrical guide has upper and low plates and side wall. The shape of plates and side wall are designed to have high resonating frequency and large amplitude of motion. The PZT also is selected to have high actuating force and high speed of motion. The support has symmetrical and rigid characteristics.

  • This paper analyzes the vibration characteristics within the cargo compartment of a three-wheeled cargo bike when used on both regular roads and dedicated bicycle lanes. When cargo is loaded into the cargo compartment of a cargo bike and driven on the road, the shocks and vibrations transmitted from the ground can potentially affect the transported goods and even lead to product damage. As the vibration characteristics applied to the cargo compartment may vary depending on the condition of the road, vibration sensors were attached to the cargo bike's cargo compartment for data collection during operation on different road types. According to KS T ISO 13355 standards, the cargo bike can withstand vibrations within the range of 10 Hz to 60 Hz when operating on both bicycle lanes and regular roads. However, it is observed that there are peaks exceeding the profile in the frequency range of 3-6 Hz. In the 70-200 Hz range, the profile is exceeded on both regular roads and bicycle lanes, with a tendency for higher exceedance on bicycle lanes. The Grms value within the frequency range of KS T ISO 13355 is 5.926 m/s2 (0.604 Grms). When operating on bicycle lanes with cargo, the Peak envelope optimization PSD value is 6.553 Grms, while on bicycle lanes, it is 7.708 Grms, indicating a difference of at least tenfold.
