The contact force between the pantograph and the catenary is a key factor determining the current collection quality, as they can ensure stable electrical power to the train. In this study, we analyzed the dynamic contact force for HEMU-430X depending on the train speed. It was confirmed through the results that the standard deviation of the contact force increases with an increase in the train speed. It was also verified that the span of the catenary system is a very important factor with regard to the contact force when analyzed with frequency analysis. To secure stable power in speed that exceeds 400km/h, the statistical variation of the contact force should be minimized. To realize this, the catenary tension was increased and the mass of the pan-head was decreased. The ensuing effects were then quantitatively analyzed in terms of the contact force. In addition, the differences in the contact force between a tunnel and an open field were analyzed based on a frequency analysis.

Deck wetness phonomena has long been considered as one of the factors that degrade the performance of a ship in waves. In rough weather, the frequent shipping of water may give rise to the capsizing of the ship. Therefore an appropriate above water bow design is an improtant assert to a ship of which successful performance in rough weather is a prerequisite such as a warship. In this paper the experimental technique for estimation of deck wetness frequency is presented. The results of the model tests are compared with those of calculation using Ochi's formula. Finally the applicability of Ochi's formula is discussed.

The causes and treatment of alopecia are concluded based on the records found successive oriental medicine in order to persuade new treatments for alopecia as following : 1. In the context of modern medical science male-dominated alopecia was referred as dok-rak(禿落), cho-dok(早禿), chon-dok(全禿), pal-ju-tal-bal, chu-bal-sun and pal-sun(髮癬) alternatively, while alopecia areata was refereed as yu-pung(油風), pan-dok(斑禿), kwi-ji-du and kwi-che-du(鬼剃頭). 2. The causes of alopecia is related with condition of Gi(vital energy) and Hyul(blood) in the twelve channels, such as weakening of vital energy in the conduits, condition of internal organs as heat in the lung, weak kidney or liver vitality, and eating habits such as severe ingestion of bitter taste or sweet taste food. Other distinct reasons are penetration of wind and dryness into a head due to weakening Gi and Hyul inside human body, flaring up of the asthenic fire due to excessive eatings, hard labour or psychological sufferings deficiency of blood, deficiency of vital essence of kidney, phlegm caused by dampness and heat, and stagnated blood. 3. According to demonstration of alopecia, the causes of alopecia areata are listed as internal wind due to heat of blood, deficiency of liver and kidney, blookage of channels and collaterals by stagnated blood, and causes of male-dominated alopecia are listed as wind dryness caused by heat of blood, dampness and heat, and heat, wind and dryness due to deficiency of blood.

This study aims to identify the awareness and performance level of hospital infection control in medical technicians working in small and medium-sized hospitals. The experiment was conducted in 235 medical technicians (medical laboratory technologist, radiological technologist, and physical therapist), and for statistical processing, SPSS Ver.23.0 was used to conduct mean and standard deviation, analysis of variance, and regression analysis. As a result, it was found that the major cause of improper infection control was lack of experts ($3.17{\pm}1.18$) and performance level was statistically significantly lower than awareness of infection control. "I took no measures after infection accident" was responded the highest at 40.0%(94 persons), and in "I reported to the head of department after disinfection, examination, and/or vaccination," the standardized regression coefficient ${\beta}$ was -0.265, p=0.025, which suggested that there was a significant negative (-) impact. Infection control level showed a significant positive correlation with training and infection control instructions. Therefore, it was found that medical technicians in small and medium-sized hospitals required high skilled manpower in infection control, training, infection control instructions, etc. Through this study, more effective infection control is considered to be possible.

This paper describes a method for vision-based person identification that can detect, track, and recognize person from video using multiple cues: height and dressing colors. The method does not require constrained target's pose or fully frontal face image to identify the person. First, the system, which is connected to a pan-tilt-zoom camera, detects target using motion detection and human cardboard model. The system keeps tracking the moving target while it is trying to identify whether it is a human and identify who it is among the registered persons in the database. To segment the moving target from the background scene, we employ a version of background subtraction technique and some spatial filtering. Once the target is segmented, we then align the target with the generic human cardboard model to verify whether the detected target is a human. If the target is identified as a human, the card board model is also used to segment the body parts to obtain some salient features such as head, torso, and legs. The whole body silhouette is also analyzed to obtain the target's shape information such as height and slimness. We then use these multiple cues (at present, we uses shirt color, trousers color, and body height) to recognize the target using a supervised self-organization process. We preliminary tested the system on a set of 5 subjects with multiple clothes. The recognition rate is 100% if the person is wearing the clothes that were learned before. In case a person wears new dresses the system fail to identify. This means height is not enough to classify persons. We plan to extend the work by adding more cues such as skin color, and face recognition by utilizing the zoom capability of the camera to obtain high resolution view of face; then, evaluate the system with more subjects.

As environmental regulations on carbon emissions are strengthened worldwide, the existing internal combustion engine-centered automobile industry is being reformed. In particular, large buses and large cargo trucks are pointed out as one of the main causes of environmental destruction due to excessive carbon emissions. The E-Highway power collection system, which has recently been proposed as a solution, uses the vehicle's battery as a backup power source or regenerative braking, depending on whether the pan head of the pentograph installed in the vehicle is in contact with the overhead line. It is used to store the excess energy generated. However, wear through contact due to continuous contact reduces the current collection effect and causes failure. In this paper, by using the current difference, the horizontal position information of the panhead in contact with the overhead line is acquired, thereby reducing the abrasion of the conductor and the panhead Make it possible to follow the overhead line. The position estimation method proposed in this paper simply configures a device that can detect the position of the overhead line of the pantograph by the difference in resistance. It is economical and has the advantage of reducing the volume. The characteristics of the pantograph estimating the location of overhead lines were analyzed using the difference between the two currents of the current collector, the feasibility of the positioning estimation system was verified through simulations and experiments.

Objectives: To study the clinical features of the primary nasal/nasopharyngeal non-Hodgkin's lymphomas and to evaluate the implication of immunophenotyping as a prognostic factor. Patients and Methods: From January 1990 to December 1997,41 patients(median age, 41 years) of primary nasal/nasopharyngeal non-Hodgkin's lymphoma were studied. The clinical records and paraffin-embedded tissue blocks were reviewed retrospectively. The histologic features, immunophenotypic findings(pan-T, pan-B, CD3, CD56) and Epstein-Barr virus in situ hybridizatios were examined. The prognostic factors for clinical outcome were evaluated in these patients. According to Ann-Arbor system, there were 30 patiets(73%) with stage IE, 4(10%) with stage IIE, 3(7%) with stage IIIE, 4(10%) with stage IVE lymphoma. Among the patients with stage IE/IIE, 4 patients received local radiation alone, 4 received chemotherapy alone, 25 received combination chemotherapy and radiotherapy and 1 refused treatment. The patients with stage IIIE/IVE were given combination chemotherapy and radiotherapy. Results: Immunophenotyping were performed in 40 patients and staining results were as follows: 3(7%) patients with B cell, 17(42%) with T cell, 18(44%) with NK/T cell(CD56 positive), and two patients with unclassifiable result. Epstein-Barr(EB) virus in situ hybridization were performed in 28 patients and 23(82%) patients had positive EBV-encoded RNAs(EBERs). 21(55%) patients achieved a complete remission. There was no difference in complete remission between radiation alone and combination therapy. With median follow-up of 30 months, 5-years disease free survival of complete responders was 60% and 5-years overall survival rate was 36%. Multivariate analysis showed that better overall survival was related with absence of B symptoms, ECOG performance${\leq}1$ and non-NK cells. Conclusion: Most of all cases were positive for EBER. Since NK/T phenotype carried the worst prognosis, analysis for CD56 expression should be done. Further prospective studies were warranted to evaluate the role of chemotherapy in stage IE/IIE.

Using superoxide dismutase (SOD)-deficient mutants of Saccharomyces cerevisiae, the oxygen toxicity induced by paraquat was studied. In aerobic culture condition, yeasts lacking MnSOD (milochondrial SOD) showed more significant growth retardation than CuZnSOD (cytoplasmic SOD)-deficient yeasts. However, not so big differences in growth pattern of those mutants compared with wild type were observed under anaerobic condition. When exposed to paraquat, the growth of yeasts lacking CuZnSOD was severely affected by higher than 0.01mM of paraquat in culture medium. By the analysis of several cellular components ivolved in free radical generating and scavenging system, it was found that, under aerobic condition, the content of lipid peroxides in cell membrane as well as cellular activity of glutathion peroxidase of CuZnSOD-deficient mutants was increased in the presence of paraquat, although significant decrease of catalase activity was observed in those stratns. In MnSOD-deficient yeast, however, increment in cellular activity of glutathion peroxldase and catalase by paraquat was observed without any deterioration of membrane lipid. It implies that the lack of mitochondrial SOD could be compensated by both of glutathion peroxldase and catalase, but that only glutathion peroxidase might act for CuZnSOD in cytoplasm. In contrast, all of SOD-deficient mutants showed a significant decrease in catalase activity, but slight increase in the activities of glutathion peroxidase, when cultivated anaerobically in the medium containing paraquat. Nevertheless, any significant changes of lipid peroxides in cell membranes were not observed during anaerobic cultivation of SOD-deficient mutants. It suggests that a little amount of free radicals generated by paraquat under anaerobic condition could be sufficiently overcome by glutathion peroxidase but not by catalase.
