Objective: This study was designed to evaluate the effects of endogenous LH surge, GnRH agonist (GnRH-a) or human chorionic gonadotropin (hCG) as ovulation trigger on pregnancy rate by intrauterine insemination (IUI). Method: Patients received daily 100 mg of clomiphene citrate (CC) for 5 days starting on the third day of the menstrual cycle followed by human menopausal gonadotropin (hMG) for ovulation induction. Follicles larger than >16 mm in diameter were present in the ovary, frequent LH tests in urine were introduced to detect an endogenous LH surge. Final follicular maturation and ovulation were induced by GnRH-a 0.1 mg (s.c.) or hCG $5,000{\sim}10,000$ IU (i.m.) administration except natural ovulation. Pregnancy was classified as clinical if a gestational sac or fetal cardiac activity was seen on ultrasound. Results: There were no differences in age, duration of infertility and follicle size, but more ampules of hMG were used in GnRH-a group compared to hCG 10,000 IU treated group (p<0.05). Lower level of estradiol ($E_2$) on the day of hCG or GnRH-a injection was observed in hCG 10,000 IU group than other treatment groups (p<0.01). The overall clinical pregnancy rate was 19.8% per cycle (32/162) and 22.2% per patient (32/144). Pregnancy rate was higher in natural-endogenous LH surge group (37.5%, 9/24) than GnRH-a (18.8%) or hCG treated group (20.9% & 13.9%), but this difference was not statistically significant. No patient developed ovarian hyperstimulation. Abortion rate was 22.2% (2/9) in hCG 5,000 IU group. Delivery or ongoing pregnancy rate was 37.5% (9/24), 18.8% (3/16), 16.3% (7/43) and 13.9% (11/79) in endogenous LH surge, GnRH-a, hCG 5,000 IU and hCG 10,000 IU treatment groups, respectively. Conclusion: These results support the concept that use of natural-endogenous LH surge in stimulated cycles may be more effective to obtain pregnancies by IUI than GnRH-a or hCG administration.

Since Corona 19, awareness about antibacterial bacteria has changed. Hand washing after going out became a necessity. Also, fogging occurs a lot on the glasses depending on the wearing of the mask. This problem has caused a lot of discomfort in our daily life and changed our perception of antibacterial and anti-fogging. Therefore, in this study, we studied whether mugwort extract is effective in preventing antibacterial and fogging. To obtain the mugwort extract, mugwort was dried, alcohol extracted, and freeze-dried. An antibacterial test was performed using a mixture of mugwort extract, zinc oxide and natural zeolite mixed in 3:7, and a fogging test was performed using mugwort extract and other mixtures. As a result, in the case of E. coli and K. pneumoniae, which were used as test strains in the antibacterial test, the bacteria were not cultured from the medium added with 1% mugwort extract, and the antibacterial activity against representative Gram-negative bacteria was confirmed. In the anti-fog test, a 10 wt% mixture of mugwort extract showed very good results in both the hot and cold parts. We expect the mugwort extract to be effective in antibacterial and anti-fogging, thus helping to overcome Corona 19.

The purpose of this study was to test whether Yoga exercise, one of muscle relaxation, helps to relieve chronic low back paln. Sample were selected from nurses who were worked at K medical center in the period from March 18 to April 23, 1996. The sample size was fifteen. The research design was one-group pretest-posttest design. To test the major research question, this study had the following procedure. The pretest included measuring individuals' degree of pain and discomfort depending on the scope and types of an range of motion, and their pain by their activity of daily living(ADL). The treatment was conducted twice every other week. The reason why this study had twice observations was to control history effect and maturation which treat internal validity in the research design of this study. In this research design, a treatment was to expose Yoga exercise to samples. The exercise was taken in 30 minutes per day for four days in a week (Two consecutive days and twice every other day). The posttest included re-measuring the individuals' the degree of pain and discomfort, and their pain by their ADL. Several hypotheses concerning effect of Yoga exercise was analyzed by the paired t-test, comparing the difference scores between pre and post tests. The results of this study was as follows. The first hypothesis that the post-treatment group taking the Yoga exercise had the pain score lower than the pre-treatment group was supported(t=3.31, p=.005). The second hypothesis that the discomfort score of the post-treatment group had lower than does that of the pre-treatment group was supported(t=2.75, p=.016). The third hypothesis that the post-treatment group had the pain score by ADL lower than does the pre-treatment group was supported(t=5.52, p=.000). In summary, this study examined the effect of a yoga exercise, one of muscle relaxation, on those who were suffered from chronic low back pain. The effect measured by the degree of pain and discomfort with a visual analog scale was statistically significant. The degree of pain according to postures in ADL also showed statistical significance. These findings showed that a yoga exercise was effective to alleviation of chronic low back pain. A pretest-posttest control group design, however, needs to get more accurate results since the design satisfies Internal validity. Consequently, yoga as an exercise cure improves an interaction between muscles and articulations, and performance of ADL for those suffered from chronic low back pain. Furthermore, this positive impact may be an effective method as nursing intervention for their physical, mental, emotional, social, and psychological recovery.

Objectives : To gather information about the factors which influence the interest and intention of admission into charging nursing hones for the elderly(CNH), as these homes represent an important method for resolving the problems related to the rapid population aging occurring in Korea. Methods : A face-to-face interview survey was carried out with 320(men 159, women 165) patients over 60 years old who were admitted at 2 university hospitals and 5 general hospitals in the Busan area between December 1998 and March 1999. Data were analyzed through t-test, ANOVA, correlation and multiple regression analysis. Results : The mean age and years of education of the study population was 67.0 and 7.7 years, and the types of chronic degenerative disease included musculoskeletal disorders(20.1%), cerebrovascular disease(17.1%), and diabetes(14.3%). The major forms of household living arrangement prior to admission were elderly alone(22.6%), and elderly couple(33.5%), while about half of them(55.5%) didn't want to live with their children id the future. Almost half were paying medication fees by themselves(46.6%). The level of actual intention of admission$(3.07{\pm}1.39)$ into a CNH was lower than that of interest$(3.22{\pm}1.33)$(p<0.01). Multiple analysis revealed that the intention of admission increased with decreasing number of future supportive persons$(\beta=-0.107)$, lower level of activity in daily life$(\beta=-0.447)$, and longer years of education$(\beta=-0.447)$ with 32.7% of $R^2$. As for the factors which determined the admission into a CNH, the fee and facilities were considered to be most important, and professional nursing and physician's care were the most desired services. In nomenclature, they preferred 'elderly hospital' or 'elderly health center' to CNH. Conclusions : Interest in CNH is increasing recently, but existing studies about patient experiences in CHN are still limited. This study may form a basis for future examinations of the needs and uses for CNH. Active financial support and public information are considered by the authors to be important factors for the induction of welfare services for the elderly, though CNH.

Purpose: Ligament reattachment technique using a suture anchor appears to show satisfactory functional outcomes and mechanical stability compared with conventional bone tunnel technique. This study was prospectively conducted in order to evaluate functional outcomes of modified Brostrom procedures using the suture bridge technique for chronic ankle instability in athletes. Materials and Methods: Twenty eight athletes under 30 years of age were followed for more than two years after undergoing the modified Brostrom procedure using the suture bridge technique. Functional evaluation consisted of the foot and ankle outcome score (FAOS), foot and ankle ability measure (FAAM) score. Range of motion and time to return to exercise were evaluated using a periodic questionnaire. Talar tilt angle and anterior talar translation were measured through stress radiographs for evaluation of mechanical stability. Results: FAOS improved significantly from preoperative mean 59.4 points to 91.4 points (p<0.001). Daily living and sport activity scores of FAAM improved significantly from preoperative mean 50.5, 32.5 points to 94.8, 87.3 points, respectively (p<0.001). Talar tilt angle and anterior talar translation improved significantly from preoperative mean $16.8^{\circ}$, 13.5 mm to $4.2^{\circ}$, 4.1 mm at final follow-up (p<0.001). Times to return to exercise were as follows: mean 10.2 weeks in jogging, 15.4 weeks in spurt running, 13.1 weeks in jumping, 11.5 weeks in walking on uneven ground, 9.1 weeks in standing on one leg, 7.2 weeks in tip-toeing gait, 8.4 weeks in squatting, and 10.6 weeks in descending stairs. Conclusion: Modified Brostrom procedure using the suture bridge technique showed satisfactory functional outcomes for chronic ankle instability in athletes. Optimal indication and cost-effectiveness of the suture bridge technique will be studied in the future.

The digital tachograph is a device that automatically records speed and distance of a vehicle, together with the driver's activity and vehicle status at an accident. It records vehicle speed, break status, acceleration, engine RPM, longitude and latitude of GPS, accumulated distance, and so on. European Commission regulation made digital tachographs mandatory for all trucks from 2005. Republic of Korea made digital tachographs mandatory for all new business vehicles from 2011 and is widening the range of vehicles that must install digital tachographs year by year. This device is used to analyze driver's daily driving information and car accidents. Under a car accident that makes the device reliability unpredictable, it is very important to store driving information with maximum reliability for its original mission. We designed and implemented a practical digital tachograph. This paper presents a storage scheme that consists of a first storage device with small capacity at a high reliability and a second storage device with large capacity at a low cost in order to reliably records data with a hardware at a low cost. The first storage device records data in a SLC NAND flash memory in a log-structured style. We present a reverse partial scan that overcomes the slow scan time of log-structured storages at the boot stage. The scheme reduced the scan time of the first storage device by 1/50. In addition, our design includes a scheme that fast stores data at a moment of accident by 1/20 of data transfer time of a normal method.

Both genetic and environmental factors play important roles in the pathogenesis of Parkinson Disease(PD). The contribution of many environmental factors including dietary factor remains unproven. The purpose the study was to investigate the dietary habits, nutrient intake and dietary quality of Korean PD patients according to the duration of disease. PD patients were recruited from K and S university hospitals from May 2005 to January 2006. This study was carried out after approval by the Institute Review Board(IRB). British Brain Bank criteria was used to diagnose PD. The subjects were classified into 2 groups based on the duration of PD: <25 months and $\geq$25 months groups. General characteristics, anthropometric measurements, food habits and dietary intakes were investigated. The results of this study were as follows: 1) The mean age of <25 months group($66.9{\pm}8.0$ yr) was significantly higher than that of $\geq$25 months group($62.2{\pm}8.8$ yr)(p<0.05). No significant differences were found for academic background, occupation, living status and social activity, however, numbers of diseases, exercise and family history of PD were significantly different. 2) Anthropometric measurements were not different between the two groups. 3) The frequency of taking snacks was significantly higher in <25 months group and the amounts of alcohol consumption were significantly higher in $\geq$25 months group. 4) Daily intakes of most nutrients were very low compared with DRI. 5) The MAR score was significantly lower in <25 months group(p<0.05;) however, the scores of DVS, DDS and DQI were not significantly different. As a conclusion an overall nutrient intake and dietary quality of the Parkinson's Disease patients need to be improved regardless of duration of the disease and a well-balanced diet should be emphasized.

The effect of dietary Antartic krill(Euphausia Superba) meal on the performance of broiler chicks during the acute phase responses was studied. One d-old male broiler chicks(Avian) were fed on the experimental basal (0.0 % krill meal), and 0.5 and 1.0 % krill meal diets, and then the acute phase response were activated by injecting Salmonella typhymurium lipopolisaccharide(LPS) three times i. p. at 8, 10 and 12 day of age. The 1.0% krill meal diet group had reduced daily gain and feed efficiency during the acute phase response of the 2nd week of age, while during recovery from the acute phase response of the 3rd week of age the lowered performance disappeared. The acute phase response increased the relative weight of liver and spleen, and dietary krill meal enhanced the activities of MnSOD and Cu/ZnSOD in liver and erythrocyte cytosols during the acute phase response, although neither the acute phase response or dietary krill meal affected significantly PHA-p hypersensitivity. The results indicated that dietary krill meal affected the performance and SOD activity of broilers chicks during the acute phase response.

Two experiments were conducted to examine the effects of the acute phase response on the performance and superoxide dismutase(SOD) activities in liver and erythrocyte of broiler chicks fed dietary krill meals A and B in experiment 1 and krill meal A in experiment 2. The experimental diets are basal diet based on yellow corn and soybean meal and diets substituted 2.0% of krill meal A or B with soybean meal of the basal diet, respectively. Day-old birds fed on the experimental diets and the acute phase response(immunological stress) was activated in the birds on 8-day of age by alternate day injection i.p. with 3 doses the Salmonella typhymurium lipopolysaccharide(LPS) in saline. The values during the acute phase response were compared with those controls injected with saline. The performance; daily gain, feed intake, and feed efficiency were different between dietary krill meal A and B in birds during the acute phase response and in the control. The acute phase response increased relative liver and spleen weights. Recovery of birds from the immunological stress was different between krill meals. Dietary krill meals increased activities of MnSOD and Cu/ZnSOD in erythrocyte cytosols during the actute phase response. Dietary krill meals did not affect the PHA-p response. The results indicated that the dietary krill meals may accentuate oxidative stress during the acute phase response.

This study was performed to determine the levels of depression symptoms among community elderlies and to reveal its related factors, specifically aimed at revealing social and family supports. The interviews were performed, during the period from July 1, to August 31, 2010, to 412 elderlies in urban areas. As a results, significantly higher level of depression symptoms was laid on those with lower social supports and family supports(p=0.000), and the subjects' depression was a negative correlation with social and family support. On multiple regression analysis, the level of depression symptoms was influenced by the variables of social and family support, with or without disability of visual acuity, sense of satisfaction in daily life, number of friends, educational level, with or without spouse, activity of hobbies and urinary incontinence. In conclusion, the level of depression symptoms was so complicatedly influenced by variable factors as well as socio-demographic characteristics, health-related behaviors, health status, social support net-work and social activities. Especially, the level of depression symptoms was more influenced by social supports and family supports.
