The purpose of this study was to identify the effect of college women s active and passive smoking on menstrual discomfort. The subjects were 252 college female students (active smokers, 71; people who passively inhaled others smoke, 104; nonsmokers who also didn't inhale others smoke, 77). Subjects were selected from 5 colleges in North Kyong Sang Province, Korea. Data was collected from March to June of 2000 with a structured questionnaire. The instruments used for this study were the revised Menstrual Distress Questionnaire (MDQ) developed by Moos(1968), general characteristic, menstrual characteristic, and smoking characteristic scale developed by researchers. The data were analysed by the SPSS/PC+ program. The results were as follows 1. There was no statistically significant difference of menstrual discomfort level among the active smokers, those who passively inhaled others smoke, and who did not inhale others smoke(F= 2.613, p= .075). 2. The mean score of menstrual discomfort was moderate(M= 60.8008, SD= 17.9243). The level of menstrual discomfort was various (minimum score 29.00- maximum score 110.0). 3. Factors influencing menstrual discomfort were on life stress events(F= 4.057, p = .045), irregular menstrual cycle(t = 3.968, p = .047), and amount of flow during menstruation(F = 4.018, p = .019). The recommendations from this study are necessity of further studies to investigate how heavy active and passive smoking have effect on menstrual discomfort.

Background: There is little information about the objectivity of posttraumatic growth experienced by cancer patients. So, the aim of present study was to investigate the viewpoints of family caregivers regarding posttraumatic growth in cancer patients. Materials and Methods: This descriptive study was conducted in one referral medical center in East Azerbaijan Province in northwest of Iran. 120 primary family caregivers of cancer patients participated with a convenience sampling method. The Posttraumatic Growth Inventory (PTGI) and Perception about Prognosis Scale (PPS) were applied for data collection with analysis performed using SPSS statistical software. Results: Family caregivers believed that their patients had a good prognosis (score 3.95 from 5). The total score of PTGI was 60.7 (SD=18.8) that indicates a moderate level of growth as reported by family caregivers. Conclusions: Family caregivers of cancer patients have incorrect viewpoints about the prognosis of their patients and reported moderate levels of growth. These findings showed that posttraumatic growth among cancer patients is an objective phenomenon.

We propose a pixel-level automatic calibration circuit scheme that initializes a capacitive fingerprint sensor LSI to eliminate the influence of the surface condition and environment, which is degraded by dirt during long-time use, process variation and ambient temperature. The sample chip is fabricated on $0.35{\mu}m$ standard CMOS process. The calibration is executed by optimizing the reference voltage in each pixel to make the sensor signals of all pixels the same. The calibration control circuit is composed of the sensing circuit and charge pumping circuit, and calibrates all pixels in a short time. 16-level gray scale fingerprint images can be captured to increase the accuracy of identification. This confirms that the scheme is effective for capturing consistent clear images during long-time use.

The purpose of this study is to investigate the preference of the hand and the sensibility image of underwear textiles according to seasons. According to a recent survey of 109 college students, using a 7 scale evaluation to the preference of the hand and the sensibility image among 13 summer and 10 winter underwear textiles. The data was analyzed through mean, SD, factor analysis, t-test, Person correlation analysis and regression analysis using SPSS Win 11.0. The summer underwear textiles were classified according to six tactile factors: stiffness/surface unevenness, weight, elasticity, moistness, extension, and warm-cool and 3 sensibility image factors: elegant individual, modern, and sporty-casual. The winter textiles were classified according to six tactile factors: stiffness/surface unevenness, elasticity, warm-cool, drapability, moistness and flexibility and divided into 2 sensibility images: modern elegant and sporty-casual. Factors expressing hand and sensibility image according to season showed significant difference. In the summer, weight, in the winter, drapability and flexibility showed significant difference at the hand factor evaluation. The hand factors: weight, warm-cool and modern sensibility image factors effect the preference of summer underwear textile, also the hand factors-elasticity, stiffness/surface unevenness and the sensibility image factor-easy-sport-casual-effect the preference of winter textiles. Therefore, the thin, light, and cool textiles which are also gorgeous and sporty-casual are preferred for summer underwear textiles while soft, simple and comfortable textiles are preferred for winter textiles.

In this paper, we propose the method that analyzes the depth of object using 2 images in the disparity algorithm. It also presents the design and implementation of the proposed method for a real time processing. The proposed system uses the vertical strip structure for calculating similar pixel numbers for the processing and converts the depth of object into gray scale images in order to be displayed on various display devices. The hardware using the proposed method is operating with 30 frames/sec and verified by using the Altera APEX 20K1000EBC652-3. The proposed method is also Implemented into It by using the Hynix 0.35${\mu}{\textrm}{m}$ CB35 ASIC library and 256PQFP package.

Purpose: The purpose of this study was to determine factors that affect poor quality of life (QOL) of older adults who received home health service. Method: The sample 492 older adults participated in the study. The QOL was measured using the scale of QOL of Ware and other data were collected through face-to-face interviews from September to August, 2009. Results: The level of QOL was moderate (Mean 24.4, SD 7.4). The QOL was poorer in older adults (p<.05) and in those living alone (p<.01) compared to older adults and those living with couple or family respectively. The QOL was positively correlated with a sense of mastery (r=.213, p<.05), connection of health (r=.160, p<.05) and a cognitive function (r=.119, p<.01), and negatively correlated with Activities of Daily Living (r=-.266, p<.01) and Instrumental Activities of Daily Living (r=-.339, p<.01). Sense of mastery, connection of health & welfare, and IADL were significant predictors of QOL. Conclusion: Finding suggest that home health service program should incorporate strategies for increasing sense of mastery and capability of performing IADL, and strengthening connection of health service that may improve QOL of older home health service recipients.

Purpose: The purpose of the study was to identify the pain patterns and factors affecting low back pain in middle-aged women with backache. Method: A descriptive research design was utilized. The participants were middle-aged women who visited to two back pain clinics in Wonju from October, 2006 through February, 2007. A total of 195 low back pain patients agreed to participate in this study, and data from 177 were analyzed. Data were collected using a questionnaire which included a modified short-form Korean pain rating scale, demographic factors, factors related to low back pain and health behavior. Descriptive statistics and multiple regression analysis was utilized in the analysis. Results: The mean score for low back pain was relatively low(M=21.57, SD=11.44). Among pain patterns, scores for dull pain were the highest of all the dimensions. In the regression analysis, significant factors affecting low back pain were found to be age, level of education, religion, BMI, experience of pregnancy, delivery type and exercise. These variables explained 24.8% of variance in low back pain(F=3.79, p<.001). Conclusion: These results suggest that nurses need for assessment and intervention to take into consideration pain patterns as well as factors affecting middle-age women with backache.
