Meniere's disease is not a life-threatening but lift-altering inner ear disease characterized by episodic vertigo, fluctuating hearing loss, tinnitus and ear fullness. The etiology and pathophysiology symptoms is still disputed. Thereby the treatment of Meniere's disease is empirical. As yet no treatment has prospectively modified the clinical course of condition and thereby prevented the progressive hearing loss. We experienced two cases of Meniere's disease treated with oriental medical treatment, acupuncture and herbal medication. 15 year-old and 23 year old male patients had diagnosed Meniere's disease by western medical doctor. After treatment their vertigo is decreased and the level of hearing loss was rise up. Therefore, oriental medical treatments could be safe and effective methods.

A mathematical model has been developed for the simulation of static stability of agricultural tractors. The model was based on Reichmann's model but modified to improve its shortcomings for practical applications. Two examples of model simulation were presented and showed its usefulness in evaluating the control and stability loss boundaries.

This research reports on a qualitative analysis of email facilitated reflective dialogue with seven college students whose parent dies. The study was exploratory in considering cultural values on intact family and asked the question: What do children experience after parental death in terms of the relationships with intra and extrafamily systems? Young adult children of single parent family expressed that they felt social pressure to practice filial piety toward their single parent. They made efforts to fulfill the social expectation and to achieve social desirability. Social stigma from extrafamily systems affected the experiences of the bereaved children. In terms of intrafamily system, young adult children tend to idealize their deceased parent. Single parents depended on the young adult children, which made parent-child relationship enmeshed or conflicting. The holistic view of the study highlights the importance of interactions between individuals and the intra and extra family systems when understanding family loss experience of the bereaved young people.

Two-photon fluorescence microscopy was performed on the enamel-dentin junction area of a human tooth using a femtosecond pulsed laser. We obtained a clear image contrast between the bright dentin and dark tubules with the autofluorescence generated from the endogenous fluorophores in dentin. The autofluorescence shows a broad spectrum due to complex cross links between dentinal collagens, which extend from blue to orange wavelengths (470-590 nm), but a gradual autofluorescence loss in photobleaching was observed for a long-term exposure under strong excitation. For increasing excitation power, we found that two-step decay becomes significant in the spectrally integrated autofluorescence.

This paper presents the first domestic model product of hybrid Insulation low-loss type pole transformer, with increased overload ability, increased life, reduced loss, focusing improved short-circuit characteristics. The capacity of this transformer is 100 KVZ, rates first voltage 13200 V and secondary voltage 230/115 type. The volume of model transformer that was produced in high temperature using hybrid insulation can be reduced to 10-20% in comparison with that of present transformer with the same capacity. In this paper, we did short-circuit test and tested general characteristics of model transformer. In addition, we suggested design application new concept and methods thorough this experiment.

Back ground & Objectives : Bilateral sudden sensorineural hearing loss(SSNHL) is very rare disease. This is the first case report in the oriental medical literature. This study describes a case of bilateral SSNHL with incomplete recovery. Methods : We treated 1 patient who had SSNHL sequentially in both ears. He received oriental and western medical treatments for more than 2 weeks and measured the hearing recovery. For diagnosis on this case, pure tone audiometry was used. The degree of improvement was evaluated by Siegel's Criteria. Results & Conclusions : This patient discharged without hearing improvement. For bilateral SSNHL patients, the result of treatment is important for their qualities of life. But the recovery rate of hearing in bilateral SSNHL is lower than unilateral SSNHL. The oriental medical therapy had some theraputic effects on SSNHL and the theraputic effects on bilateral SSNHL requires further study.

The primary purpose of the safety management is to prevent the loss of lives or physical damages arising from potential hazards in the railway signaling system. Since such potential hazards may occur at any time during the system life-cycle from design and development to maintenance, safety management activities have to be continuously taken in the course of the system life-cycle. In this paper, presented for Safety Activity Process. (Phase, Methods, Documentation)

The aim of of the study is a powerful test for the discrimination and therefore an optimal desin for that purpose. This problem is studied by Chernoff ([5]) and used in Chernoff ([6]) for accelerated life tests using the exponential distribution for life times. The approach used here is similar to that suggested by Lauter ([10]) and used in Chaloner ([3]) and Chaloner and Larntz ([4]) where it is motivated using Bayesian arguments. The approach taken in this paper the loss function $L(\cdot)$ evaluating a test procedure and a design d.

Purpose: The purpose of this study was to identify factors related to the quality of life of patients with ulcerative colitis. Methods: A total 116 patients with ulcerative colitis were asked on general characteristics, illness-related characteristics, depression, and quality of life. The collected data were analyzed by t-test, ANOVA, and stepwise multiple regression. Results: As for depression the 81.03% were normal, the 8.62% were mild depression, the 6.90% were moderated depression, and the 3.45% were severe. As for quality of life, the social functions was highest, followed by intestine-related symptoms, systemic symptoms, and emotional functions. Quality of life was positively correlated to subjective health status, age, and body mass index, and negatively to depression. Main factors affecting the quality of life included depression, subjective health status, physician's global assessment, age, days of loss in social life, and present abdominal pain. Conclusion: Physical and psychosocial health problems related to ulcerative colitis affected the quality of life of the patients. Further research is warranted for developing educational programs and psychosocial strategies in order to efficiently handle the illness.

This paper reviews the mechanical effects produced by reinforcement corrosion of prestressed concrete beams. Specifically, modifications in the bonding of the tendon to the concrete that reduce service life and load bearing capacity are studied. Experimental information gathered from previous works has been used for the theoretical analysis. Relationships between bond stress loss and reinforcement penetration in the concrete, and concrete external cracking were established. Also, it was analysed the influence that has the location of the area affected by corrosion on the loss magnitude of the initial prestress.
