Purpose: This study was aimed to identify the effect of self-foot reflexology on the relief of premenstrual syndrome and dysmenorrhea in high school girls. Method: Study subjects was 236 women residing in the community, teachers and nurses who were older than 45 were recruited. Data was collected with self administered questionnaires from July 1st to August 31 st, 2003 and analysed using SPSS/WIN 10.0 with Xtest, t-test, and stepwise multiple logistic regression at a significant level of =.05. Result: The breast cancer screening rate was 57.2%, and repeat screening rate was 15.3%. With the multiple logistic regression analysis, factors associated with mammography screening were age and perceived barriers of action, and factors related to the repeat mammography screening were education level and other cancer screening experience. Conclusion: Based on the results, we recommend the development of an intervention program to decrease the perceived barrier of action, to regard mammography as an essential test in regular check-up, and to giveactive advertisement and education to the public to improve the rates of breast cancer screening and repeat screening.

Background: The celiac plexus and splanchnic nerves are targets for neurolytic blocks for pain relief from pain caused by upper gastrointestinal tumors. Therefore, we investigated the analgesic effect of a celiac plexus block versus a splanchnic nerve block and the effects of these blocks on the quality of life six months post-intervention for patients with upper GIT tumors. Methods: Seventy-nine patients with inoperable upper GIT tumors and with severe uncontrolled visceral pain were randomized into two groups. These were Group I, for whom a celiac plexus block was used with a bilateral needle retrocrural technique, and Group II, for whom a splanchnic nerve block with a bilateral needle technique was used. The visual analogue scale for pain (0 to 100), the quality of life via the QLQ-C30 questionnaire, and survival rates were assessed. Results: Pain scores were comparable in both groups in the first week after the block. Significantly more patients retained good analgesia with tramadol in the splanchnic group from 16 weeks onwards (P = 0.005, 0.001, 0.005, 0.001, 0.01). Social and cognitive scales improved significantly from the second week onwards in the splanchnic group. Survival of both groups was comparable. Conclusions: The results of this study demonstrate that the efficacy of the splanchnic nerve block technique appears to be clinically comparable to a celiac block. All statistically significant differences are of little clinical value.

Purpose As medical radiation exposures on patients are being social issues an interest in a relief of radiation exposures on patients is increasing. Further, there are many cases where some patients among who are getting PET/CT tests choose to get implanted with metal artifacts in their bodies. This study is to find out effects of presence or absence of metal artifacts when dose change or CT attenuation correction for the relief of radiation exposures are applied using phantoms through changes in standard uptake value (SUV). Materials and Methods GE company's Discovery 710 machine was used for PET/CT test equipments. We used NEMA IEC body phantoms. We also used screw and mesh cage made of titanium which are used in real clinical processes for the metal artifacts. Two experiments were conducted: One is to test and measure repeatedly about SUV about differences in CT attenuation corrections according to dose changes and another is to do the same procedure for SUV about the presence and absence of the metal artifacts. We injected $^{18}F-FDG$ into NEMA IEC body phantoms with a TBR ratio of 4:1 and then put the metal material into the transformation phantoms. Once a scanning for the metal artifacts was done we eliminated the metal artifacts and went on non-metal artifacts. For the each two experiments, we scanned repeatedly with CT kVp (140, 120, 100, 80) and mA (120, 80, 40, 20, 10) for an experimental condition. For PET, we reconstructed each with standard AC (STD) technique and quantitation achieved cnsistently QAC) technique among CT attenuation correction methods. We conducted a comparative analysis on measured average values and variations which were measured through repeated measure of SUV of region 1, 2, 3 spheres for each conditions of non-metal /metal scan. Results For each kVp, 120, 80, 40 (mA) of non/metal (screw, mesh cage) showed low frequency of fluctuation rates of above 2%. In 20, 10 mA above 2% of fluctuation rates appeared in high frequency. Also, when we compared the fluctuation rates of STD and QAC techniques in non/metal (screw, mesh cage) tests QAC technique showed about 1-10% of differences for each conditions compared to STD technique. In addition, metal types did not have significant effects on fluctuation rates. Conclusion We confirmed that SUV fluctuation rates for both STD and QAC techniques increase as dosage is lower. We also found that the SUV of PET data was maintained steadily in a low dosage for QAC technique when compared with STD technique. Hence, when the low dosage is used for the relief of radiation exposures on patients QAC technique may be exploited helpfully and this could be applied in the same way for patients with metal artifacts implanted in their bodies.

Objective : This retrospective study aimed to compare clinical outcomes in terms of pain relief and recurrence rate between fragmentectomies and conventional microdiscectomies in patients with lumbar disc herniation (LDH). Methods : Between January 2008 and May 2011, a total of 175 patients met the inclusion criteria of this study. The visual analogue scale (VAS) scores of back and radicular pains were recorded before surgery, 2 and 6 weeks after surgery. Recurrence was defined when a patient had the same pattern of preoperative symptoms and was confirmed with magnetic resonance imaging. Results : Seventy-four patients (42.3%) were suitable for fragmentectomy, and 101 patients underwent conventional microdiscectomy. There were no significant differences in VAS scores between the fragmentectomy and conventional microdiscectomy groups 2 and 6 weeks after surgery. During the follow-up period, 3 patients (4.05%) in the fragmentectomy group and 7 patients (6.93%) in the conventional microdiscectomy group relapsed. Conclusion : If patients are selected according to well-defined criteria, fragmentectomy can be a good surgical option for LDH, in the physiological aspect of preserving healthy intervertebral disc materials.

Adhesion strength of electroless-plated Ni, Ni-P and Cu deposites on alumina substrate has been studied. Grain boundary spaces produced on the substrate surface by etching treatment provided anchoring sites for enhancing the adhesion strength. Adhesion strengths of Ni-P and Ni deposit were higher than that of Cu deposit, because of higher initial nucleation rates than the latter. The electroless-plated Ni-P and Ni underlayer improved the adhesion strength of the Cu deposit. In could be attributed to the enhanced adhesion between the substrate and those underlayers as well as the satisfactory adhesion between Cu deposits and those underlayers. Heat treatment was also conducted in order to enhance the adhesion strength of Cu layer. The strength was enhanced by about 19% when the treatment was conducted at $150^{\circ}C$ for 2 hours. The enhancement was attributed to relief of internal stress and release of hydrogen.

Total ankle replacement has been performed for treatment of end stage arthritis of the ankle, hopefully being an alternative to ankle arthrodesis. However, due to its high failure rates, earlier versions of ankle replacements were not regarded as successful procedures. The latest design has shown increasingly positive results. Total joint replacement of the ankle itself is still regarded as a demanding procedure and much more challenging than that of the hip and knee in many aspects. Several studies, however, have pointed out that it is becoming the viable, accepted alternative for arthrodesis with advanced implants, appropriate patient selection, and proper training experience of procedures. Compared with arthrodesis, it shows equal or better outcomes in pain relief, range of motion, and patient's satisfaction. We are attempting to review its biomechanical characteristics, implant design, indications, complications, clinical outcomes, and survival rate.

Despite the lack of evidence-based standard guidelines to select the best surgical treatment option for end-stage ankle osteoarthritis, the rate of total ankle arthroplasty (TAA) is increasing rapidly relative to ankle arthrodesis (AA) with the development of implant designs and surgical techniques. Physicians and patients would benefit from a more comprehensive understanding of the differences in postoperative pain relief, functional improvement, the rates of complication or reoperation, and restoration of gait ability and sports activity. This paper overviews the current consensus on indications and contraindications for TAA and provides a literature review on a comparison of the clinical and functional results between TAA and AA.

For the estimation of prevalence state of major chronic adult disease and their relationships with drinking and smoking habits in the Korean employees, we analyzed a medical check-up data of 155,799 subjects that was accumulated during the year of 2008. In age and sex distribution of the sample, male subjects were 106,229 and female 51,827 showing the ratio of 2:1 and the majorities were 30s and 40s covering 70.7% of the total. The prevalence rates of major chronic diseases were obesity 29.8% (male 38.3%, female 12.3%), hypertension 4.1%, HBV carrier inactive 3.3%, diabetes mellitus 2.9%, hypothyroidism 1.7% (male 1.3%, female 2.4%), hyperlipidemia 1.1%, hyperthyroidism 1.4% (male 1.1%, female 2.1%), osteoporosis 1.4% (male 1.4%, female 1.4%), anemia 0.9% (male 0.3%, female 2.0%) and renal disease 0.9%. The frequency of and volume of drinking in male group were 4.6 times and 7.5 times higher than female group respectively. The 33.8% of the workers were smoking currently. In the serological tests, all the items such as AST, ALT, ${\gamma}-GTP$, LDH for liver function, Cholesterol, TG, uric acid for hyperlipidemia and BP systolic, Fasting blood sugar, BMI for metabolic syndrome were significantly higher in the more drinking and more smoking groups than other groups (p<0.001). The higher prevalence rates in male group in the liver disease seems to be strongly related with the drinking and smoking habits in male employees. We suggest that employees should rather relying on leisure or hobbies than drinking and smoking for the stress relief.

In July 1989, Korea had achieved the national medical insurance system comprehensively covering the whole population since its inception of 12 years before, and subsequently the plural medical insurers had integrated to the unique health insurer system in July 2000. But there yet remain some problems to be improved under low contributions rates and poor benefit packages, especially the shortage of assuring beneficiaries' rights. The Health Insurance Appeal System is composed of a two-tiered system of committee. The Formal Objection Committees built in the National Health Insurance Corporation and in the Health Insurance Review Agency respectively examine the formal objections to the decisions of the Corporation, or the Review Agency. And the Dispute Mediation Committee built under the command of the Minister of Health and Welfare reviews the protests against the decisions on the formal objections by each Formal Objection Committee. To cope with the appellant in relation to the administration on the qualification of the insureds, contributions, and insurance benefits etc, is found to be unsatisfactory. There's the reason of poor function on right-relief caused by the loose composition of the Appeal Committee, the deficit of people's recognition and P.R., the lack of professional manpower and the Committee's independency, and time lag in making decisions and so on. Consequently the Appeal System should be improved to secure the rights-relief function, to empower the professionalism of the Appeal Committee, to strengthen P.R. for the beneficiaries, to build up the staff's proficiency through training, and to develop the quality of administrative services.
