Objective: This study reports one case of polycythemia vera patient treated with oriental medicine in conjunction with conventional medicine. Methods: One patient who was diagnosed with polycythemia vera was treated using different modalities of herbs, acupuncture, and pharmacopuncture. An herbal formula, Yongdamsagan-tang was given three times a day with daily acupuncture treatment session, in addition to Soyeom and Jahageo pharmacopuncture injection which were administered three times a week. After treatment, patient's symptoms and blood test results were observed and analyzed. Results: After ten days of treatment, the patient had shown improvements in symptoms of headache, dizziness, tinnitus, and itchiness. Two months later, laboratory findings continued to be kept within the normal range and the intervals of phlebotomy therapy has extended to three months. Conclusions: This case study shows minimum evidence of safety and efficacy of oriental medicine for managing symptoms of polycythemia vera. Considering this is only a short term, single case study, further research is needed to confirm these results.

Purpose: The purpose of this study was to learn the affective factors of case managers' occupational stress. Method: A total of 986 participants responded to a self-administered questionnaire that included 24 items of Korean Occupational Stress Questionnaire Short Form (KOSQSF), job satisfaction index, health behaviors, general characteristics, and variables related to work. The data collection of research was done from 17th to 21th of September, 2007. The data were analysed by t-test, ANOVA, and multiple regression with SPSS 11.1 package program. Result: The results of this study were as follows: The overall job satisfaction rate of men and women was highly than that of the Korean worker's standard. There were statistically significant differences in occupational stress in work place, work department, work position, smoking, treatment in out-patient clinic, subjective & relative health-status, work load, supervisor's review on work-ability, and job satisfaction. According to the multi-variate analysis, occupational stress(47.6%) was related to job satisfaction, workload, individual work-ability, supervisor's review on work-ability, health status and gender. Conclusion: Occupational stress varied depending on the ten variables and was influenced by job satisfaction(35.7%) and 5 other variables. The results suggest that further follow-up study on case managers is necessary to relieve their occupational stress.

Background: This study examines the clinical effect on quality of life of herbal medicine and local acupuncture point stimulation administration for a cervicogenic dizziness (CGD) patient. This case report was described in accordance with CARE guidelines. Case Report: A 25 year-old female patient suspected to be suffering from CGD was examined. The patient was treated with herbal medicine and local acupuncture point stimulation. We used the Headache Impact Test-6 (HIT-6), Dizziness Handicap Inventory (DHI), Pittsburgh Sleep Quality Index (PSQI), 36-Item Short Form Health Survey Version 2 (SF-36v2), and verbal numerical rating scale (VNRS) to assess the patient's symptoms. As new herbal medicine and local acupuncture point stimulation were applied, dizziness, headache, and neck pain symptoms improved. Quality of life affected by the symptoms significantly improved. Adverse effects were not observed. Conclusions: This study may suggest that herbal medicine and local acupuncture point stimulation may be effective therapy for the treatment of typical symptoms in patients with CGD.

Objectives: This study aimed to introduce a clinical case of asymptomatic microhematuria due to suspicion of kidney trauma following a motor vehicle accident. Methods: A 19-year-old male was hospitalized with the chief complaint of back pain after a motor vehicle accident. He showed an elevated urine red blood cell (RBC) level in the laboratory test, although no specific traumatic lesions were present on the body. He was assessed to have asymptomatic microhematuria, and Zhu Ling Tang (polyporus decoction) was given to him to be taken three times daily. Results: After the treatment, the level of urine red blood cells returned to normal range. Adverse events were not observed. Conclusions: Zhu Ling Tang caused a short-term improvement in the urinalysis levels of a patient with asymptomatic hematuria. However, further studies are needed, as this study is only a single-case report.

The objective of this research is to assess the seismic performance of different types of electrical cabinets in nuclear power plants. The cabinets under investigation are: (a) Case 1: a short single cabinet; (b) Case 2: a tall single cabinet; (c) Case 3: separated cabinets; and (d) Case 4: a combined cabinet with coupling effects. To accurately capture the real behavior of the cabinet, three-dimensional finite element models are developed using ANSYS with connection non-linearity. Frequency domain decomposition (FDD) is used to determine the dynamic properties of the cabinets from shaking table testing data, and these results are utilized to validate the numerical model. The close match between the experimental and numerical results obtained from the modal analysis demonstrates the accuracy of the numerical model. Subsequently, transient structural analysis is performed on the validated models to explore seismic performance. The results show that the acceleration response of the combined cabinet is lower than the single cabinet and the separated cabinet. This observation suggests that top anchors used to combine two different types of cabinets play a crucial role in assessing the efficiency and seismic resistance of electrical cabinets in a nuclear power plant.

This study developed the pants pattern, that improved appearance and gesture functions in clothes to resolve inconveniences in case of activities with being adequate in fitness of slim-fit pants for obese adolescents. The slim-fit pants pattern was developed through the fitting test after designing and making the pattern of the experimental clothing A(c/pu; 99/1%) with the primary commercial clothing as basic prototype, through the fitting test and implementation of the experimental clothing, modified and supplemented secondarily, and through the fitting test of the second experimental clothing, modified and supplemented tertiary. In terms of findings, first, as a result of analyzing the commercial slim-fit pants, it is interpreted to have projected an optical illusion, that appears to be slim due to being narrow in width of the front panel when observed from the front of the pants. Second, in the fitting test of the first experimental clothing, the prototype of commercial clothing was understood to have improved butt, crotch, waist and femoral regions. Third, pattern design of the second experimental clothing was allowed to decline abdominal pressure, in case of the sitting position, by making the crotch line in the front panel short and by handling it with a yoke belt, and was processed a difference between waist and hip circumference in the back panel, with a rubber band in the whole waist part. Fourth, in the gesture function test of the third experimental clothing, high evaluation was received in every item excluding the knee region.

Bioconcentration factors of some carbamates BPMC, carbaryl and carbofuran were determined. The tested fishes were zebrafish (Brachydanio rerio) and red sword tail (Xiphophorus hellieri). The fishes were exposed to 0.05 ppm, 0.01 ppm, 0.50 ppm, one- hundredth concentration of 96-hrs $LC_{50}$ and one-thousandth concentration of 96-hrs LCso and test periods were 3, 5 and 8 days. Obtained results are summerized as follows: In the case of BPMC and carbaryl, BPMC and carbaryl concentration in zebrafish extract and BCF s of BPMC, carbaryl were lower than those of red sword tail, and increased as increasing test concentration. In the case of same experimental concentrations, BPMC concentration in zebrafish extract and $BCF_s$ of BPMC were decreased as prolonging test periods. In the case of same experimental periods, carbaryl concentration in zebrafish extract and BCF s of carbaryl were decreased as increasing test concentration, especially dropped at 0.50 ppm. Carbofuran did not bioaccumulate in zebrafish for test periods, in the case of red sword tail, it was impossible to calculate on $BCF_s$ data because test concentration of one-hundredth and one-thousandth of 96hrs $LC_{50}$ was under the detecting limit on GC. Test concentration of 0.05 and 0.10 ppm were the same tendency with BPMC and carbaryl. Determined depuration rate conatant were highest on carbofuran, and followed by carbaryl, and BPMC. It is suggested that low BCF of carbofuran is due to its relatively high water solubility and depuration rate, compared to BPMC and carbaryl. Therefore, carbofuran had no little bioconcentration effect on the aquatic ecosystem.

In this paper, we propose a ESP(Extended Scan Path) architecture for multi- board testing. The conventional architectures for board testing are single scan path and multi-scan path. In the single scan path architecture, the scan path for test data is just one chain. If the scan path is faulty due to short or open, the test data is not valid. In the multi-scan path architecture, there are additional signals in multi-board testing. So conventional architectures are not adopted to multi-board testing. In the case of the ESP architecture, even though scan paths either short or open, it doesn't affect remaining other scan paths. As a result of executing parallel BIST and IEEE 1149.1 boundary scan test by using, he proposed ESP architecture, we observed to the test time is short compared with the single scan path architecture. Because the ESP architecture uses the common bus, there are not additional signals in multi-board testing. By comparing the ESP architecture with conventional one using ISCAS '85 bench mark circuit, we showed that the architecture has improved results.

Introduction: Although continuing education is necessary for practicing nurses, it is very difficult to organize traditional classes because of large numbers of nurses and working shifts. Considering the increasing development of mobile electronic learning, we carried out a study to compare effects of the traditional face to face method with mobile learning delivered as text messages by cell phone. Materials and Methods: Sixty female nurses working in our hospital were randomly divided into class and short message service (SMS) groups. Lessons concerning breast cancer screening were prepared as 54 messages and sent in 17 days for the SMS group, while the class group participated in a class held by a university lecturer of breast and cancer surgery. Pre- and post-tests were undertaken for both groups at the same time; a retention test also was performed one month later. For statistical analysis, the paired T test and the independent sample T test were used with SPSS software version 16; p<0.05 was considered significant. Results: Mean age and mean work experience of participants in class and SMS groups was $35.8{\pm}7.2$, $9.8{\pm}6.7$, $35.4{\pm}7.3$, and $11.5{\pm}8.5$, respectively. There was a significant increase in mean score post-tests (compared with pretests) in both groups (p<0.05). Although a better improvement in scores of retention tests was demonstrated in the SMS group, the mean subtraction value of the post- and pretests as well as retention- and pretests showed no significant difference between the 2 groups (p=0.3 and p =0.2, respectively). Conclusions: Our study shows that teaching via SMS may probably replace traditional face to face teaching for continuing education in working nurses. Larger studies are suggested to confirm this.

A study on a creep-fatigue crack growth behavior has been carried out for a cylindrical structure with weldments by using a structural test and an evaluation according to the assessment procedures. The creep-fatigue crack growth behavior following the creep-fatigue crack initiation has been assessed by using the French A16 procedure and the conservatism for the present structural test has been examined. The structural specimen is a welded cylindrical shell made of 316 L stainless steel (SS) for one half of the cylinder and 304 SS for the other half. In the creep-fatigue test, the hold time under a tensile load which produces the primary nominal stress of 45 MPa was one hour at $600^{\circ}C$ and creep-fatigue loads of 600 cycles were applied. The evaluation results for the creep-fatigue crack propagation were compared with those of the observed images from the structural test. The assessment results for the creep-fatigue crack behavior according to the French Al6 procedure showed that the Al6 is overly conservative for the creep-fatigue crack propagation in the present case with a short hold time of one hour.
