  • Internal spline forming using a thin and long tube can cause the buckling and folding during the forming process. In the study, we proposed two different extrusion processes, and we performed the analysis in order to obtain the optimal process according to the length of land part. Using the rigid-plastic finite element simulation, the proposed processes have been compared by checking the deformed shape and stroke-road relation.

  • The presteamed or prefrozen persimmon blocks of 10cm ${\times}$ 10cm ${\times}$ 15cm were air-dried at room temperature until about 30% moisture content, and then were dried in a MW oven. During drying their internal temperatures were monitored with thermo-couple probes. The presteamed and prefrozen blocks didn't show any improvement in drying rate and moisture gradient when compared with the controls. Checks appeared on the surfaces of most presteamed blocks during air-drying. It has been clearly revealed that the maximum weight, loss must, be less than 2g/min during MW drying to prevent internal checking and that MW drying reduced moisture gradients inside blocks. MW dried the persimmon blocks 440 times faster than conventional kiln.

  • Obejectives : To investigate the clinical effect of electroacupuncture and bee venom acupuncture for benign prostatic hyperplasia(BPH) symptoms. Methods : Among 39 outpatients who were treated at a BPH clinic, 8 were finally selected for analysis by charts-review, retrospectively. They were treated by electroacupuncture and bee venom acupuncture more than 3 times. We estimated the effectiveness of the treatments by using the International Prostate Symptom Score (IPSS) questionnaire and checking their nocturia frequency. On the basis of these variables, we analyzed the statistical significations of symptom improvements. Results : Among 8 patients, the IPSS and nocturia frequency showed significant improvement after the final treatment compared with baseline (P = .0078, P = .0078). The IPSS significantly decreased even after the 1st treatment and also after the 2nd treatment compared with the baseline (P = .0078, P = .0078). The IPSS at post final-treatment, post 1st- and post 2nd treatment also showed significant improvement compared with IPSS at baseline in 6 severe symptomatic patients(P = .031, P = .031, P = .031). Nocturia frequency decreased after the 1st treatment compared with baseline and showed significant improvement between baseline and post 2nd treatment (P = .0078). Conclusions : In a retrospective and cross-sectional study investigating the clinical effects of electroacupuncture and bee venom acupuncture on BPH, these treatments proved to have significant therapeutic effects, particularly for various symptoms involving frequent nocturia.

  • The article examines the stage of verification of a crime report from the standpoint of the need for its legislative regulation. Moreover, it investigates the international experience in this field. The existing procedural models are described in detail on the example of the neighboring and faraway countries. An analysis of the provisions of the current criminal procedure law of Russia and foreign experience allowed the authors to identify existing problems in the implementation of departmental control and prosecutorial supervision at the stage of verifying a crime report. The aim of the study is to develop theoretical provisions and recommendations regarding the implementation of departmental procedural control and prosecutorial supervision over the activities of the investigator during the verification of reports of crimes, based on the study of experience, both in Russia and in a number of countries of the near and far abroad, which could find their reflection in law enforcement practice, as well as aimed at improving the current criminal procedure legislation. The authors substantiated the theory that a detailed examination of the foreign procedural foundations of checking a crime report will allow us to form the most suitable model for checking a crime report for our state, taking into account all possible features and successfully implement it into the current criminal procedural law of the Russian Federation.

  • Purpose: Nursing students face constant threats of blood-borne infections such as HIV, Hepatitis B, and Hepatitis C during their clinical rotation period. This study was done to determine the frequency and risk of the exposure to blood and body fluids. Methods: The data was collected using a questionnaire. Ninety eight junior & senior nursing students were participated in this study. Results: 75.6% of the participants reported more than once during practicum. The exposure occurred most frequently while checking the blood glucose (65.3%). The general ward (45.3%) was the most frequent site for the occurrence of the exposure. However, only eight cases (10.7%) were reported to the medical or nursing personnel in charge. Conclusions: This study shows nursing students are in a great risk of the exposure to blood & body fluid. The risk is highest in the general ward during checking the blood glucose. Thorough education on preventive measures, should be provided to nursing students prior to clinical practium.

  • Oil filters for vehicular parts are used under high and low temperatures as the engine is cooled, and defects can be generated with repeated changes in the operating environment and with changes in the shape, such as very high internal losses for the bolts. Visually checking for defects inside a bolt is impossible. Nondestructive evaluation methods such as eddy current testing (ECT) are recommended as a more effective way to examine inside a bolt and detect surface defects in a short amount of time. In this study, the fit bobbin coil eddy current probe was applied to checking the bolts. The bolt parameters were calculated by using a COMSOL analysis program to obtain parameters for professional interior design and fault diagnosis.

  • Objectives: Ryodoraku is a physiological function test using electric current. Since it can evaluate the patient's overall condition as well as a function of individual organs, Ryodoraku can be assumed as an effective way to diagnose chronic obstructive pulmonary disease (COPD). Therefore, this study aimed to investigate the values of Ryodoraku for diagnosing COPD. Methods: We designated a COPD group, who were over 40 and satisfying COPD criteria, $FEV_1$/FVC<0.7. The Control group also consisted of members over 40 years old but without COPD and any other lung disease. We conducted a comparative study by checking the Ryodoraku score (RS), the average of Rt.&Lt. H1 (mean H1), the mean difference value between both H1s (${\mid}H1^R-H1^L{\mid}$) and the ratio of patients whose RS was under 40. Then we investigated the correlation between the mean H1 and the results of pulmonary function test (PFT). Results & Conclusions: In the COPD group, RS, mean H1 and ${\mid}H1^R-H1^L{\mid}$ were significantly lower and the ratio of 'RS<40' patients was meaningfully higher than in the Control group. On the other hand, PFT seems not to be replaced by Ryodoraku since there was no correlation between mean H1 and the results of PFT. Though more experiments and researches are needed to be further confirmed, Ryodoraku is expected to be an adequate way for prediagnosing and following up the COPD patients.

  • This study purports to understand the direct and indirect effects between eating disorder behavior of female adolescents and their body-related variables(concerning the degree of diet regime, weight control, body satisfaction, and obesity), self-esteem and internal control, by checking three sub-categorized behavior of eating disorders of diet behavior, bulimia behavior, and eating control behavior. The sample group used for the study consisted of 190 female high school students and 292 female university students; measurement devices used for the study were those of body-related variables, self esteem and internal control, and eating disorder behavior; and data analysis was performed using ${\chi}2$, t-test, Pearson's correlation, regression analysis and path analysis. The results are as follows. First, there is a significant difference between university students and high school students regarding their body satisfaction, weight control experience, and self esteem. University students are more satisfied with their body, have higher self esteem, and control their weight better than high school students. Second, diet behavior shows a correlation with the degree of diet interest, weight control experience, and body satisfaction. Body satisfaction and internal control proved to be correlated with bulimia behavior, while weight control experience, obesity, and self esteem were correlated with eating control behavior. Third, the variables that showed a direct influence on diet behavior as an eating disorder are diet interest, weight control experience, body satisfaction and obesity, in that the explanatory power of the variables is 60.7% with the highest mark on obesity. The variables that showed effects on bulimia are body satisfaction and internal control with an explanatory power of 2.8%. Indirect variables effecting bulimia include objects, diet interest, body satisfaction, and self esteem. The variable with a direct influence on eating control behavior was self esteem with and explanatory power of 4%, whereas the variables of objects, diet interest, body satisfaction, weight control experience, and internal control were all indirectly correlated with eating control behavior.

  • Background: The purpose of this study was to report the improvement of a patient with one-and-a-half syndrome, vertigo, and paresthesia caused by acute primary pontine hemorrhage (PPH) after a combination treatment of traditional Korean and Western medicine. Case report: A 51-year-old female with one-and-a-half syndrome, vertigo, and paresthesia after PPH was treated with Korean medicine, including herbal medication, acupuncture, and moxibustion, and Western medicine, including medication and rehabilitation therapy during hospitalization. Her progress was evaluated by checking for changes in symptoms with the extraocular muscle (EOM) function test, numeral rating scale (NRS), and follow-up brain computed tomography scans and magnetic resonance imaging (MRI). After 41 days of treatment, the EOM movement was improved, leaving limited abduction of the left eye. The NRS scores for vertigo and paresthesia decreased from 10 to 5 and from 10 to 3, respectively. Improvement was noted in hematoma in MRI, but a new ischemic lesion was also discovered. Conclusion: This case reports the clinical course of one-and-a-half syndrome and suggests that a combined therapy of traditional Korean and Western medicine can be useful for PPH patients with one-and-a-half syndrome, vertigo, and paresthesia. However, studies of larger populations are required.
