The purpose of this study was to examine which aspects of coresident intergenerational relationships were associated with the life satisfaction of unmarried children in established adulthood and of their parents. In this study, the coresident relationship characteristics included support exchange, emotion, interference-conflict, and perceptions of coresidence. Data were collected from (a) 250 never-married adults who were 35+ years old and lived in Seoul with at least one parent aged 75 years or younger and (b) 250 older adults who were 75 years old or younger and had at least one unmarried child aged 35+ years living in the same household. Our multiple regression analysis of unmarried children showed that the adult child's financial support, the adult child's psychological reliance on parents, the parent's psychological reliance on the child, and relationship quality were significantly related to higher levels of life satisfaction. In contrast, the parent's daily interference, daily conflicts, and anticipation of future care of parents were related to lower levels of life satisfaction. Second, the characteristics that were positively associated with the parent's life satisfaction were the parent's instrumental support, relationship quality, the coresident child's daily interference, positive perceptions of intergenerational coresidence, and expectation of future care of parents. In contrast, the parent's financial support, daily conflicts with the child, and taking intergenerational coresidence for granted were negatively related to the parent's life satisfaction. This study advances our understanding of coresidence between unmarried children in established adulthood and their older parents by focusing on the multiple aspects of intergenerational coresidence.

Pain management is a major issue in caring of cancer patients. Patients' concerns for reporting pain and taking analgesics are patient-related barriers to the management of cancer pain. Since such study has not been done at all in Korea, it is clearly needed to study on these problems. The purpose of this study is to attain basic data in order to improve cancer pain management in Korea. This is done by: 1) examining the extent of patients' concerns that might be barriers to the optimal pain management, and the extent of related factors (pain management hesitancy, adequacy of using analgesics, pain severity and pain interference); 2) identifying the relationship between patients' concerns and the related factors. The data has been collected from 180 cancer patients who were hospitalized in medical wards of one university hospital in Seoul, Korea during the period from November 1, 1997 to February 28, 1998. The data has been collected through interviews with (1) Barriers Questionnaire - Korean Version (BQ-K); (2) Hesitancy Experience Questionnaires (HQ); (3) Pain Management Index (PMI); (4) Brief Pain Inventory (BPI); and (5) Demographic Data. The data were analyzed by descriptive statistics and by t-test, One-way ANOVA, Pearson correlation using SPSSWIN program. The Results are as following: 1) The mean scores of Pain Management Concerns (PMC) by BQ-K were toward the moderate with a little high points(2.59). Most of the patients (99.4%) had some extent of concerns (over lout of maximum 5 points). Among the eight subscales of BQ-K, the Pain Management Concerns (PMC) about 'Fear of tolerance' was the highest (3.80) and 'Worry about side effects' was the least (1.40). 2) The extent of Pain Management Hesitancy (PMH) by HQ of wnom had pain on the day of the interview was a little higher than moderate score(5.53 out of maximum 10 points). 6.7% of the patients with experiencing pain used less adequate analgesics for the severity of pain than they were expected. 27.8% of them never used any analgesics at all. The mean score of pain severity by BPI was 16.59 (maximum: 40), and that of the interference with daily life by BPI was 32.03 (maximum: 70). 3) The patients who were older, less educated, and in low socio-economic status were likely to have more concerns. Pain Management Concerns (PMC) was positively correlated with Pain Management Hesitancy (PMH) (r=.75), pain severity (r=.44) and pain interference (r=.50). Those who were not using adequate analgesics had higher Pain Management Concerns (PMC) than did those who were using adequate analgesics (t=-5.42). The patients who had more Pain Management Concerns (PMC) tended to hesitate more to report pain and to use analgesics. They used more inadequate analgesics for the severity of pain and also had experienced more pain severity and interference with daily life. In conclusion, the patients' concerns for reporting pain and for using analgesics are major patient-related barriers to cancer pain management in Korea. The patients' concerns were correlated significantly with the level of the hesitancy experience, inadequate use of analgesics, the pain severity and the interference with daily life. Considering this, an educational program for cancer patients under the treatment with analgesics should be developed in order to solve these problems.

This study evaluated the Comparison of the Effectiveness of Pelvic Floor Muscle exercise and Biofeedback treatment for Genuine Stress Incontinence I assigned 60 participants to 2 groups : 30 to the pelvic floor muscle exercise group and 30 to the biofeedback group. Treatment protocol lasted for 6 weeks. Peak pressure, and duration time of pelvic muscle contraction were evaluated by a perineometer. Lower urinary symptoms, sexual matter and life style scores were achieved by using Jackson's scale. The treatment efficacy of the pelvic floor muscle exercise is compared with the biofeedback group and the main results of the comparison are as follows : 1. Pelvic muscle contraction 1) The peak pressure in the biofeedback group was significantly increased(P＝0.000). 2. The frequency and quantity of incontinence 1) The frequency of incontinence in the biofeedback group was significantly decreased(P＝0.000). 2) The quantity of incontinence in the biofeedback group was significantly decreased(P＝0.000). 3. The lower urinary symptoms Daily frequency(P＝0.000), nocturia(P＝0.000), urgency(P＝0.000), bladder pain(P＝0.000), unexplained incontinence(P＝0.048), wearing protection(P＝0.022), changing outer clothing(P＝0.005), hesitancy(P＝0.008), intermittent stream(P＝0.000), abnormal strength of stream(P＝0.004), retention(P＝0.000), incomplete emptying(P＝0.000), and inability to stop mid stream(P＝0.006) of the lower urinary symptoms in the biofeedbatk group were significantly decreased. 4. The sexual matters The dry vagina (P＝0.004) and pain during sexual Intercourse (P＝0.002) in the biofeedback group was significantly decreased. 5. The life style The fluid intake restriction(P＝0.007), affected daily task(P＝0.003), avoidance of places & situation(P＝0.003), interference in Physical activity (P＝0.002), interference in relationship with other people(P＝0.01), and feeling about the rest of life with urinary symptom(P＝0.000) in the biofeedback group were significantly decreased. In conclusion, the biofeedback treatment was more effective than the pelvic floor muscle exercise in genuine stress incontinence.

Interference can cause serious problems in our daily life. Traditional ways in localizing a target can't work well when it comes to the source of interference for it may take an uncooperative or even resistant attitude towards localization. To tackle this issue, we take the BPSN (Binary Proximity Sensor Networks) and consider a passive way in this paper. No cooperation is needed and it is based on simple sensor node suitable for large-scale deployment. By dividing the sensing field into different patches, when enough patches are formed, good localization accuracy can be achieved with high resolution. Then we analyze the relationship between sensing radius and localization error, we find that in a finite region where edge effect can't be ignored, the trend between sensing radius and localization error is not always consistent. Through theoretical analysis and simulation, we explore to determine the best sensing radius to achieve high localization accuracy.

Remarkable developments in the electric and electronic industry have given people's daily life much more convenience and abundance. However, in electrical communication, or electric and electronic fields, making electrical and electronic devices more functional, more integrated, and faster have put electromagnetic interference(EMI) into more complex forms, and lots of problems such as interruption, malfunction, or interference by noise between electrical communication systems occurs every day. In this research, the electromagnetic compatibility(EMC) filter in the high powered breaker was designed and fabricated as a counter measure. The filter attenuated noise more than 20${\sim}$50 dB in the range of 10 MHz${\sim}$1.5 GHz. And, when the electric fast transient(EFT) of 4 kV in the level 4 of IEC 61000-4-4 was induced, it was soon suppressed to 600 V.

The purpose of this study was to examine the effect of stress types and coping styles on the relationship quality with mothers-in-law perceived by sons-in-law. The data was collected from 300 sons-in-law aged 20~49 by using a survey questionnaire. The main results of this study were as follows: first, factor analysis yielded 4 types of coping(cognitive understanding coping, avoidant coping, direct behavior coping, and indirect behavior coping) and 7 types of stress(despising poor ability and condition, interference in daily life, son-in-law discrimination, wife discrimination, uncomfortable interaction, differences in lifestyle, and excessive demand). Second, the total stress perceived by sons-in-law in the relationship with their mothers-in-law was affected by avoidant coping and cognitive understanding coping. Finally, the relationship quality between mothers-in-law and sons-in-law was influenced by avoidant coping, uncomfortable interaction stress, direct behavior coping, differences in lifestyle stress, son-in-law discrimination stress, interference in daily life stress, frequency of meeting, cognitive understanding coping, indirect behavior coping, and age. Consequently, it was confirmed that sons-in-law's coping styles with stress from their mothers-in-law was more influential than the amount of stress perceived by sons-in-law on the relationship quality with their mothers-in-law. Especially, 'avoidant coping' among 4 styles of coping and 'uncomfortable interaction stress' among 7 types of stress influenced the relationship quality between mothers-in-law and sons-in-law the most.

Electromagnetic interference (EMI) shielding is an important issue in modern daily life due to the increasing prevalence of electronic devices and their compact design. This study estimated EMI-shielding effect (EMI-SE) of small ($8-14{\times}17mm$) Hanji (Korean traditional paper) doped with carbon nanotubes (CNTs) and compared to Hanji without CNT using $^2H$ (92.1 MHz) and $^{23}Na$ (158.7 MHz) nuclear magnetic resonance (NMR) peak area data obtained from 1 M NaCl in $D_2O$ samples in capillary tubes that were wrapped in the Hanji samples. The simpler method of using the variation of reflected power and tuning frequency by inserting the sample into an NMR coil was also tested at 242.9, 158.7, and 92.1 MHz. Overall, EMI shielding was relatively more effective at the higher frequencies. Our results validated that NMR methods to be useful to evaluate EMI-SE, particularly for small, flexible shielding materials, and demonstrated that EMI shielding by absorption is dominant in Hanji mixed with CNT.

Object detection and tracking have become one of the most active research areas in the past few years, and play an important role in computer vision applications over our daily life. Many tracking techniques are proposed, and Camshift is an effective algorithm for real time dynamic object tracking, which uses only color features, so that the algorithm is sensitive to illumination and some other environmental elements. This paper presents and implements an effective moving object detection and tracking to reduce the influence of illumination interference, which improve the performance of tracking under similar color background. The implemented prototype system recognizes object using invariant features, and reduces the dimension of feature descriptor to rectify the problems. The experimental result shows that that the system is superior to the existing methods in processing time, and maintains better problem ratios in various environments.

Purpose : Granisetron is a potent, the most selective 5-HT3 receptor antagonist and is reported to b effective in treatment of radiation-induced emesis. The antiemetic efficacy and safety of oral granisteron was evaluated in patients with receiving highly emetogenic treatment by conventional fractionated irradiation. Materials and Methods : Patients with various cancers who were being treated with irradiation were accrued into the present study. The intensity of nausea was evaluated on first 24 hours and on day-7 by patients according to the degree of interference with normal daily life as followings; a) none; b) present but no interference with normal daily life (mild): c) interference with normal daily life (moderate): and d) bedridden because of nausea (severe). Non or mild state was considered to indicate successful treatment. The efficacy of antiemetic treatment was graded as follows; a) complete response; no vomiting, no worse than mild nausea and receive no rescue antiemetic therapy over the 24h period, b) major response; either one episode of vomiting or moderate/severe nausea or had received rescue medication over 24h period, or any combination of these, c) minor response; two to four episodes of vomiting over the 24h period, regardless of nausea and rescue medication, d) failure; more than four medication. The score of the most symptom was recorded and the total score over 24 hours was summarized. The complete or major response was considered to indicate successful treatment. Results : A total of 10 patients were enrolled into this study, and all were assessable for efficacy analysis. Total nausea control was achieved in 90$\%$ (9/10:none=60$\%$ plus mild=30$\%$) of total patients after 7 days. The control of vomiting by granisteron was noted in seven patients (70$\%$) of complete response and three (30$\%$) of major response with a hundred-percent successful treatment over 7 days. The minor response or treatment failure were not observed. No significant adverse events or toxicities from granisetron were recorded in patient receiving granisetron. Conclusion : We concluded that granisetron is a highly effective antiemetic agent in controlling radiotherapy-induced nausea or vomiting with a minimal toxicity profile.
