Recently, a large amount of waste has been occurred from electric motor units (EMUs) due to the excess of their duration or the exchange of interior. In Korea, most of waste has been treated by incineration or landfill because the special treatment system of disused EMUs has not been existed until now. The objective of this study is to investigate the international railroad cases for the efficient treatment of disused EMUs. Japanese railroad makes an effort to enhance the recycling efficiency of rolling stocks such as the use of recycling materials or the development of recycling technology. Also, Europe has decided to treat the disused rolling stocks considering the inspection of their conditions and the increase of management cost. Therefore, in the future, it will be necessary to improve the domestic regulations related to the duration of rolling stocks and to develop the recycling technology of interior preferentially.

Objectives : This study was to analyze the status of patients with infertility in the department of oriental gynecology in an oriental medical hospital and propose infertility treatment in oriental medicine. Methods : This study was presented with 2,153 cases of infertile women who had visited the department of oriental gynecology in one oriental hospital in Seoul from 2002 to 2004. Results : The total number infertile patients has decreased year by year. The age range of patients was getting higher and the age group between 30 and 35 took up about one half of the total patients. The duration of infertility for less than 3 years held about 50-60% of the total patients, and the mean duration of infertility was $39.18{\pm}29.57$ months (2004). The most common occupations of females were professionals or administrative managers. The secondary infertility was increasing and unexplained infertility increased from 38.2% (in 2002) to 54.4% (in 2004). However the duration of treatment was shorter. This shows that the age range of the patients having oriental-medicine treatment is gradually getting higher and the number of the patients having oriental-medicine treatment and compliance is decreasing. Conclusions : More studies about objectification of oriental medicine need to precede any other studies. Then, it is thought to be necessary to rebuild cooperative relationships between oriental & western medicine through systematic research and political supports and to establish firm foundations of oriental medicine.

Objectives: The aim of this study is to compare the efficacy of fresh versus frozen reconstituted botulinum toxin type A (BTX-A) for the treatment of adductor type spasmodic dysphonia. Materials and Methods: After reconstitution with normal saline, BTX-A was used within 4 hours or it was kept frozen in a consumer grade freezer at about $-25^{\circ}C$ for up to 4 months. Thirty patients with spasmodic dysphonia were randomly assigned and treated with the either fresh or frozen BTX-A. About 83% of injections resulted in a satisfactory outcome with 5.3 months of mean action duration. Treatment outcomes and side effects of total 161 injections were compared along the duration of keeping BTX-A frozen. Results: There were no statistical differences in the duration of action, self-rated satisfaction score, and the duration of hoarseness and/or aspiration between fresh and frozen BTX-A treated groups. No significant side effects were observed and the frozen BTX-A were proved to be free of bacterial contamination. Conclusion: After being reconstituted and kept frozen, BTX-A may be safely used for more than 4 months without significant loss of its effectiveness or additional side effects.

Objectives The purpose of this study is to examine 33 cases of chronic sinusitis in children who were treated with Korean medicine. Methods Herbal medicine, acupuncture, and nebulizer and laser therapy were used to treat chronic sinusitis, and a plain radiography (paranasal sinus water's view) was used to confirm improvement of the children's sinusitis. Then, the data was classified by sex, age, frequency and duration of common cold, severity of sinusitis, duration of treatment, pattern identification and so on. Results There were 72.7% boys and 27.3% girls. The average age of children is $4.48{\pm}2.18years$. 70% of the children had common cold more than once a month, and 85.1% of the children from the study group had common cold lasting more than a week. The sinusitis severity score ranged from 10 to 200. 81.8% were more than 100. Duration of the treatment was $157.21{\pm}83.4day$, duration of herbal medicine treatment was $79.3{\pm}31.23day$, rate of herbal medicine was $62.12{\pm}29.21%$. The frequency of acupuncture, nebulizer and laser therapy ranged from 1 time to 11 times but was much lower than expected. Conclusions 33 cases of chronic sinusitis in children were treated with Korean medicine, and cure of the illness was confirmed by PNS water's view, and clinical characteristic of the patients with chronic sinusitis was analyzed.

Purpose: With the increasing prevalence of orthodontic treatment in adults, clear aligner treatments are becoming more popular. The aim of this study was to evaluate the effect of orthodontic treatment on periodontal tissue and to compare orthodontic treatment with fixed appliances (FA) to clear aligner treatment (CAT) in periodontitis patients. Methods: A total of 35 patients who underwent orthodontic treatment in the Department of Periodontology were included in this study. After periodontal treatment with meticulous oral hygiene education, patients underwent treatment with FA or CAT, and this study analyzed patient outcomes depending on the treatment strategy. Clinical parameters were assessed at baseline and after orthodontic treatment, and the duration of treatment was compared between these two groups. Results: The overall plaque index, the gingival index, and probing depth improved after orthodontic treatment (P<0.01). The overall bone level also improved (P=0.045). However, the bone level changes in the FA and CAT groups were not significantly different. Significant differences were found between the FA and CAT groups in probing depth, change in probing depth, and duration of treatment (P<0.05). However, no significant differences were found between the FA and CAT groups regarding the plaque index, changes in the plaque index, the gingival index, changes in the gingival index, or changes in the alveolar bone level. The percentage of females in the CAT group (88%) was significantly greater than in the FA group (37%) (P<0.01). Conclusions: After orthodontic treatment, clinical parameters were improved in the FA and CAT groups with meticulous oral hygiene education and plaque control. Regarding plaque index and gingival index, no significant differences were found between these two groups. We suggest that combined periodontal and orthodontic treatment can improve patients' periodontal health irrespective of orthodontic techniques.

Background: In South Korea, the number of cases of dental treatment for the disabled is gradually increasing, primarily at regional dental clinics for the disabled. This study investigated pediatric patients at a treatment clinic for the disabled within a university hospital who received dental treatment under general anesthesia. This data could assist those that provide dental treatment for the disabled and guide future treatment directions and new policies. Methods: This study was a retrospective analysis of 263 cases in which patients received dental treatment under general anesthesia from January 2011 to May 2016. The variables examined were gender, age, reason for anesthesia, type of disability, time under anesthesia, duration of treatment, type of procedure, treatment details, and annual trends in the use of general anesthesia. Results: Among pediatric patients with disabilities who received dental treatment under general anesthesia, the most prevalent age group was 5-8 years old (124 patients, 47.1%), and the primary reason for administering anesthesia was dental anxiety or phobia. The mean time under anesthesia was $132.7{\pm}77.6min$, and the mean duration of treatment was $101.9{\pm}71.2min$. The most common type of treatment was restoration, accounting for 158 of the 380 treatments performed. Conclusions: Due to increasing demand, the number of cases of dental treatment performed under general anesthesia is expected to continue increasing, and it can be a useful method of treatment in patients with dental anxiety or phobia.
