Purpose: Dysmenorrhea is a menstrual condition characterized by severe and frequent cramps and pain. Effective treatment methods for dysmenorrhea are not yet fully understood. This research compares the effects of pain killers and heated red bean pillows. Methods: Data were got on demographic data, menstrual cycle status, and activities of daily living (ADLs) limitations, dysmenorrhea severity and menstrual pain scores. Following a 10% drop-out rate, 44 young women satisfied the inclusion criteria. To prevent any bias, the experimental and control groups were selected from different campuses. We used two sizes of red bean pillows: $13{\times}11.5cm$, weighing 400g; and $15{\times}18cm$, weighing 220g. For analysis, we used IBM SPSS statistics 19.0. Results: Ninety-nine point seven percentage of total subjects reported moderate to severe dysmenorrhea and 63.6% reported as moderate to severe daily activities limitations. The mean pain score with visual analogue scale was $80.2{\pm}9.42$ of 100 and 86.4% used pain killers to alleviate menstrual discomfort in all the subjects. In both groups, all three variables showed significant improvement and the Moos's Menstrual Distress Questionnaire (MDQ) scores changed significantly between menstrual and post-menstrual time point at within groups and not significantly different at premenstrual and menstrual time point at between groups. However, the MDQ score was significantly higher in experimental group than control group at post-menstruation time point and the degree of satisfaction was higher in the control group. Conclusion: This research shows that red-bean pillows on the abdomen are effective in assisting the ADL and diminishing pain severity. With regard to its safety the study indicates it can be a convenient and safe option for female students with menstrual discomfort in schoolas a non-pharmacological self-help.

Purpose: The purpose of this study was to identify the association between physical activity and vitamin D deficiency status among Korean adolescents. Methods: This is cross-sectional analysis of Korean adolescents aged 10-18 years from the 5th Korea National Health and Nutrition Examination Survey(KNHANES 2010-2012; n=2,384). We estimated the prevalence of vitamin D deficiency and identified the correlations with the strength of physical activity. $x^2$ test, t-test, and multiple logistic regression using complex sample analysis were done. The odds ratio of vitamin D deficiency by physical activity was calculated using complex sample multivariate logistic regression analysis. Results: The prevalence of vitamin D deficiency was 78.2%. The mean serum 25 (OH) D level in deficiency group and non-deficiency group was 14.4ng/mL, 23.7ng/mL respectively. Differences by age strata (the prevalence ranging from 68.5% to 86.3%) and gender (78.6% for boy and 84.5% for girl) were identified. Among adolescents aged 16-18 or girl in vigorous physical activity, a significant correlation between vitamin D deficiency and physical activity was observed, whereas no significant correlation were found among adolescents in moderate physical activity. Conclusion: In conclusion, vigorous physical activity was associated with vitamin D deficit in Korean adolescents. Thus, intervention programs enhancing vigorous activity than moderate activity need to be developed in schools and community.

Objectives The purpose of this study is to evaluate the relationship between the severity of white matter changes (WMC), risk factors and cognitive domains, including executive function profiles. Method Forty nine subjects over 55 years with subjective memory complaints were assessed with MRI and neuropsychological tests. The WMC were assessed by MRI T2-FLAIR images and divided into 3 groups of mild vs. moderate vs. severe and 2 groups of mild-moderate vs. severe by using Mantyla's criteria and Fazeka's criteria. The risk factors were examined in hypertension, heart disease history and chemistry Lab. Medical conditions which affect to cognitive dysfunction and definite dementia were also excluded. Results Comparing 3 groups, hypertension was identified as a risk factor of the WMC. Comparing 2 groups, total cholesterol and LDL were identified for as the risk factor of WMC. The severity of WMC was significantly associated with cognitive disturbances and their main effect on cognition was working memory and inhibition. Conclusion The risk factors of the WMC in the elderly were hypertension, hyperlipidemia. The severity of WMC appears to be associated with executive dysfunction in the elderly.

The aerodynamic characteristics of circular cylinder in a channel are studied to make clear the flow feature by solving the Navier-Stokes equation based on the finite volume method with unstructured grids. Reviews are made on with the vorticity, velocity, dynamic pressure, residual and drag, where the Reynolds numbers are 50 and 100. The flows for $Re{\succeq}50$ shows the vortex shedding in the wake, and the result is the same as the case of moving cylinder. The ground effect of flat bottom results in the growth of vortex, being generated in the upper side of the cylinder and elongated in the rear. As the cylinder approaches to wall, for example 0.6, the cylinder plays as a role of blockage to obstruct the flow between the cylinder and wall. The drag coefficients are compared with others' results to confirm the validity of the present numerical simulation.

Objective : The study was to investigate Diagnosis and Treatment Based on an Overall Analysis of Signs and Symtoms(證治) of a patient on stomach cancer stage IV by means of the clinical symptoms. Methods : The observation of the clinical progress was carried out by conducting Diagnosis and Treatment Based on an Overall Analysis of Signs and Symtoms(證治) with the patient diagnosed stomach cancer stage IV. Results : Treatments such as the invigoration of qi(補氣), the flow of qi(行氣), and the relieving pain(止痛) was given because the patient showed the qi deficiency of the spleen and stomach(脾胃氣虛). There were moderate effects for anorexia, indigestion, nausea, and general weakness, but there was not any clear effect for alleviation of abdominal pain except the first period. Specially, compared with two hospitalization treatments in 1998, the third hospitalization treatment did not show any apparent improvement. It was believed that this caused by the patients bodily weakness because of deterioration of anemia from bleeding in the progress of cancer. Conclusion : Diagnosis and treatment based on an overall analysis of signs and symtoms(證治) of a patient on stomach cancer stage IV had moderate effects on the improvement of the patients condition, but in this case we had difficulty in long-term observation because of short hospitalizations or insufficient examination by an oriental-western combined medicine group.

This study was designed to investigate the effects of dietary calcium. serum estrogen level and physical activity on the bone status of 116 healthy elderly women living in urban area. Current calcium intake was assessed by convenient method(refered to as Ca intake) and calcium containing food frequency method(refered to as Ca index) Daily activity record was used for the estimation of physical activity level, and serum estrogen level was measured from fasting blood of subjects. The rate of bone resorption was evaluated by the determination of hydroxyproline(Hpr) in fasting urine with correction for creatinine excretion. The results of this study are summarized as follows : 1) Average daily Ca intake of subjects was 621.4$\pm$155.8mg, which is above the Korean recommended dietary allowances. However 44.8% of the subjects consumed Ca below RDA level. Ca index score was significantly correlated with the bone status(P<0.05), Ca intake did not show significant correlation with the bone status although a positive trend of influence was evident. 2) Average serum estrogen level of subjects was 18.7$\pm$9.8pg Contrary to our anticipation. estrogen level did not show any significant relation to age and bone status. 3) Daily physical activity was classified into four categories by activity intensity : sedentary. moderate, active and severe. The average physical activity of subjects belong to moderate level. and the bone status was significantly related to the physical activity(P<0.01) 4) Among other influential factors such as age, pocket-money. family type. drinking, smoking and BMI, there was a significant difference between bone status and BMI(P<0.05). 5) Multiple regression analysis of variables showed that physical activity has greater effect than other variables when the entire subjects were taken into account. However. eliminating the subjects whose bone status rated as excellent(Hpr/cr<0.009), Ca index showed higher correlation than physical activity. These results have demonstrated that dietary calcium intake is the primary important factor for keeping good bone health and that bone status of subjects with a sufficient calcium intake is affected by various factors such as physical activity, age, smoking. BMI and others.

Purpose: The aim of this study was to investigate prophylactic treatment effects in Korean patients with severe hemophilia A. Methods: A prospective study of 32 severe hemophilia A patients was conducted with the approval of the Institutional Review Board at the Eulji University Hospital. Two patients received primary prophylaxis; whereas, the other 30 patients were divided into 2 groups-secondary prophylaxis (n=15) and on-demand (n=15)-on the basis of their consent for secondary prophylaxis. A 20-25 IU/kg dose of factor VIII concentrate was administered to the primary and secondary prophylaxis group patients every 3 days for 1 year. The prophylactic effect was evaluated by observing changes in the Pettersson scores, annual number of total and joint bleeds, and factor VIII consumption for 1 year. Results: No moderate or severe bleeding was observed, and the Pettersson scores remained unchanged during the prophylaxis period in the patients who received primary prophylactic treatment. After the treatment was changed from on-demand to secondary prophylaxis, the annual number of total and joint bleeds in the secondary prophylaxis group decreased by $64.4%{\pm}13.0%$ and $70.0%{\pm}15.2%$, respectively. The average increase in Pettersson scores within 1 year was $0.5{\pm}0.8$ and $1.3{\pm}1.1$ in the secondary prophylaxis and on-demand groups, respectively. Prophylactic effects were also observed in patients >17 years who had nearly the same initial Pettersson scores. Conclusion: Intermediate-dose prophylactic treatment may delay hemarthropathy progression and prevent its occurrence in Korean severe hemophilia A patients.

In this paper we report some properties of inner magnetospheric structure inferred from the T01_s code, one of the latest magnetospheric models by Tsyganenko. We have constructed three average storms representing moderate, strong, and severe intensity storms using 95 actual storms. The three storms are then modelled by the T01_s code to examine differences in magnetic structure among them. We find that the magnetic structure of intense storms is strikingly different from the normal structure. First, when the storm intensity is large, the field lines anchored at dayside longitudinal sectors become warped tailward to align to the solar wind direction. This is particularly so for the field lines anchored at the longitudinal sectors from postnoon through dusk. Also while for the moderate storm the equatorial magnetic field near geosynchronous altitude is found to be weakest near midnight sector, this depression region expands into even late afternoon sector during the severe storm. Accordingly the field line curvature radius at the equator in the premidnight geosynchronous region becomes unusually small, reaching down to a value less than 500 km. We attribute this strong depression and the dawn-dusk asymmetry to the combined effect from the enhanced tail current and the westward expansion/rotation of the partial ring current.

Purpose: Women who undergo gynecological surgery have moderate and severe sensation and distress of pain despite the advent of patient controlled analgesia (PCA). The purposes of this study were to describe perception of non-pharmacological therapy for postoperative pain control and examine changes of pain sensation and distress in women who had gynecological surgery. Method: The sample consisted of 52 women who were having gynecological surgery. Subjects who agreed to participate in the study were asked for their opinion about non-pharmacological approaches for postoperative pain control using a structured study questionnaire. Pain sensation and distress were assessed by VAS in the morning and afternoon for 2 days following the surgery. Result: About 50% of the subjects thought that non-pharmacological methods such as relaxation, music, massage, or meditation would be helpful for their postoperative pain control. If both pharmacological and non-pharmacological therapy were given for pain control, 96% of subjects reported it would be effective. Nurses can apply techniques of relaxation, deep breathing, meditation, and music therapy to surgical patients along with PCA. Expected sensation and distress of pain was high, but pain levels gradually decreased over time. However, subjects experienced moderate levels of pain postoperatively although they used PCA. Conclusion: The effect of a combined method of pharmacological and non-pharmacological approach needs to be tested if postoperative pain is to be decreased more.

This study was objected to evaluate clinical progressions about both the degree of pain relief and the occurrence of morphine tolerance while the epidural analgesia with low dose of morphine, bupivacaine and antidepressant continued repeatedly at every 5 day intervals of the constant-rate infusion(0.5 ml/hr, 60 ml capacity). The subjects were divided to 56 cancer and 36 non-cancer patients who failed to respond to palliative treatments. Before the relief of pain, the pain severity was moderate(10%) and severe(90%). The dose escalation of morphine noted to 11(20%)patients in cancer pain and to one(5%) case only in non-cancer. During the epidural analgesia, the effect of pain relief was moderate(11%) and good(89%). It suggest that the morphine tolerance may be reduced to some degree such as an initial minimum dose of epidural morphine with local anesthetic and antidepressant should be adjusted on an individual basis using the constant-rate infusor, even though rapid dose escalation occurrs in some patients who the diseases progress over a short period of time.
