This study points out a problem that the vehicle rotation area provided in a dead-end parking lot for apartment blocks is misused as unreasonable parking places but accordingly, the edge parking spaces are rarely used for parking. Therefore, this study aims to establish a parking design standard to improve the parking convenience and land-use efficiency by investigating the real parking behaviors and problems identified in the study area, multiple apartment blocks in Haeundae-gu, Busan. This study calculated two simple linear regression models for two mutually exclusive factors, such as the parking convenience and land-use efficiency, respectively, and specified a trade-off point that optimizes both factors. The study results found that parking convenience and land-use efficiency can be improved by not only changing the misused vehicle rotation area to normal parking spaces depending on the usage pattern, but also by increasing the width of the edge parking spaces from 2.3m to 2.6m. Finally, this study suggests two parking design cases for more realistic design applications by considering the parking environment in the dead-end parking lot for apartment blocks.

Objectives : The aims of present study was to investigate clinical characteristics of male patients with eating disorders. Methods : The present study included 32 male patients with eating disorders and 75 female patients with eating disorders, recruited from an eating disorders specialized clinic in a university hospital, Seoul, Korea. We compared clinical characteristics of eating disorders and comorbid conditions of depression and anxiety between men and women with eating disorders. Correlations between eating disorders psychopathology in men with eating disorders and their weight suppression(WS) were investigated. Results : There was no difference in age at presentation, age of onset, illness duration, and body mass index at presentation between genders. Male patients with eating disorders had higher rates of premorbid overweight or obesity than female patients with eating disorders had. WS in the male patients was associated with the severity of their eating disorders. Conclusions : The present study provides grounds for improved understanding for clinical features of eating disorders in males.

Purpose: The Tox-Info system is a poisonous substance information database developed by the Korean National Institute of Food and Drug Safety Evaluation. The aim of this study was to estimate the coverage effectiveness of the Tox-Info system by comparing the toxic substances included in the database with the distribution of the toxic substances implicated in the cases of intoxicated patients presenting to emergency departments. The secondary aim of the study was to propose any additional substances that should be added to the database. Methods: We retrospectively reviewed the medical records of patients suffering with toxic exposure who had visited any of 12 selected emergency departments in Korea from January 2010 to December 2011. The identified toxic substances were classified into groups including prescription drugs, agricultural chemicals, household products, animals or plants, herbal drugs, and others. We calculated the coverage rate of the Tox-Info database relative to the number of intoxication cases and the type of toxic substances involved. Results: A total of 5,840 intoxicated patient records were collected. Their mean age was $46.6{\pm}20.5$ years and 56.2% were female. Of the total intoxication cases, 87.8% of the identified toxic substances were included in the Tox-Info database, while only 41.6% of all of the types of identified toxic substances were included. Broken down by category, 122 prescription drugs, 15 agricultural chemicals, 12 household products, 14 animals or plants and 2 herbal drugs involved in poisoning cases were not included in the Tox-info database. Conclusion: This study demonstrated the clinical usefulness of the Tox-Info system. While 87.8% of the substances involved in the cases were included in the Tox-Info database, the database should be continuously updated in order to include even the most uncommon toxic substances.

Purpose: Toxic alcohols are responsible for accidental and suicide motivated poisonings, resulting in death or permanent sequelae for the afflicted patients. Major therapeutic modalities in these cases include treatment with alcohol dehydrogenase inhibitors and extracorporeal elimination. There have been a number of case reports of toxic alcohol intoxication in Korea. The purpose of this study was to review the clinical characteristics of patients suffering toxic alcohol intoxication. Methods: We retrospectively reviewed the medical records of patients who presented with toxic alcohol intoxication at 8 emergency departments (ED) from Jun 2005 to Nov 2011. Patients who ingested methanol, isopropyl alcohol, ethylene glycol, and other alcohols except ethanol, were included in this study. The clinical characteristics of these patients were analyzed to include anion and osmolar gap, and estimated concentration of alcohol in the body. Results: During the study period, 21 patients were identified who had ingested toxic alcohol (methanol; 12 patients, ethylene glycol; 9 patients). At ED arrival, the mean anion gap was $18.7{\pm}6.9$ and the osmolar gap was elevated in 13 patients. Oral and IV ethanol were administrated to 11 patients in order to inhibit alcohol dehydrogenase. Extracorporeal elimination procedures such as hemodialysis were performed in 9 patients. There were no fatalities, but the one patient suffered permanent blindness. Conclusion: This study found that ethylene glycol and methanol were the substances ingested which produced toxic alcohol intoxication. The patients presented with high anion gap metabolic acidosis and were typically treated with oral ethanol and hemodialysis.

Purpose: The purpose of this study was to identify the changes in the characteristics of patients with carbon monoxide (CO) poisoning, as well as the distinctive differences in intentionally exposed patients. Methods: The medical records of CO poisoning patients, who visited nine emergency departments between January 2010 and December 2011, were reviewed retrospectively. The clinical information including age, gender, hospitalization, type of discharge, cause and location of exposure, site of onset, concentration of initial blood carboxyhemoglobin (COHb), methods of treatment and presence of neurological complications was examined. The subjects were divided into an intentional and non-intentional group and the differences between them was compared. Results: A total 209 subjects were recruited. The median age was 38 years (29~49.5 years). They frequently complained of nausea and vomiting, and the most common exposures occurred in winter, normally in the home. The cause of exposure was usually fire, followed by incomplete combustion of fuels. The median initial blood COHb was 13.15%. The proportion of intentionally exposed patients was 21%. They were significantly younger, more frequently discharged against medical advice, and showed a higher initial blood COHb level (22.85%) than the non-intentional group. Conclusion: This study suggests that those with intentional CO poisoning are normally discharged against medical advice even when they have a higher initial COHb level. An adequate explanation of the delayed neurologic sequelae and short term follow-up observation is recommended for those patients with intentional exposure.

The negative influence by disaster on human's life could be so tremendous. I like to give attention to the disaster, considerable many cases, that disaster was used as stimulation or motivation for artist's creativity, especially in the film among various art activities. The reason I focus on disaster through art activities is disaster is closely related to human's daily life and also aesthetic consciousness. I like to look into the flood disasters' appearances described in the both films, and and the people's aesthetic consciousness expressed from the flood disasters. In the traditional education of the East. 'cultivation' has been used as the meaning of self education which develops mostly one's personality by doing self practice, and self insight meditation. And In the modern western education, cultivation has been identified as the meaning of unique mission, that each human being expresses one's own individuality, that is personality, progressively. I think 'the aesthetic ' already immanence in human's mind. Analysis for The beauty of Kant is also starts from special nature, delightfulness. The aesthetic doesn't appears in sight easely because it always exists in one's bottom of heart like mist. That's the reason we try to reach to the aesthetic through the medium, that's art. Human can achieve aesthetic cultivation which reaches to the aesthetic by having lot of events and experiences in the process.

PURPOSE. This study evaluated the accuracies of different bite registration techniques for implant-fixed prostheses using three dimensional file analysis. MATERIALS AND METHODS. Implant fixtures were placed on the mandibular right second premolar, and the first and second molar in a polyurethane model. Aluwax (A), Pattern Resin (P), and Blu-Mousse (B) were used as the bite registration materials on the healing abutments (H) or temporary abutments (T). The groups were classified into HA, HP, HB, TA, TP, and TB according to each combination. The group using the bite impression coping was the BC group; impression taking and bite registration were performed simultaneously. After impression and bite taking, the scan bodies were connected to the lab analogs of the casts. These casts were scanned using a model scanner. The distances between two reference points in three-dimensional files were measured in each group. One-way ANOVA and Duncan's test were used at the 5% significance level. RESULTS. The smallest distance discrepancy was observed in the TB group using the temporary abutments. The Blu-Mousse and HP groups showed the largest distance discrepancy. The TB and BC groups showed a lower distance discrepancy than the HP group (P=.001), and there was no significant difference between the groups using the temporary abutments and healing abutments (P>.05). CONCLUSION. Although this study has limitations as an in-vitro investigation, the groups using the temporary abutments to hold the Blu-Mousse record and bite impression coping showed greater accuracy than the group using the healing abutments to hold the pattern resin record.

Background: Rhinolaryngoscopy and sputum examination are popular tests for the evaluation of chronic cough. Little is known about the relationship between symptoms and rhinolaryngoscopic findings or sputum eosinophilia in chronic cough patients. Methods: One hundred patients, who had chronic cough with normal chest radiography and who also had undergone both rhinolaryngoscopy and induced sputum analysis, were reviewed retrospectively. Eleven associated symptoms of chronic cough were asked; postnasal drip (PND) and laryngopharyngeal reflux (LPR) were examined by rhinolaryngoscopy. Induced sputum analysis was performed for evaluation of sputum eosinophilia. Cross tabulation analyses with chi-square tests were used to evaluate the relationship between symptoms and objective findings. Results: The most frequent symptom was sputum (70%). The prevalence of PND and LPR on rhinolaryngoscopy were 56% (56/100) and 25.6% (22/86), respectively. Sputum eosinophilia was observed in 23 (23.7%) of 97 patients. The dyspnea (p=0.001), sputum (p=0.003), nasal obstruction (p=0.023), and postnasal drip sense (p=0.025) were related with PND on rhinolaryngoscopy. LPR on rhinolaryngoscopy was not related with any symptoms. Dyspnea (p=0.003), wheezing (p=0.005), nasal obstruction (p=0.013), and belching (p=0.018) were related with sputum eosinophilia. Conclusion: Any symptoms might not be related with LPR on laryngoscopy. Some symptoms might be related with PND on rhinoscopy or with sputum eosinophilia.

Objectives The purpose of this study is to report the effect of Megadose Pharmacoacupuncture combined with conservative Korean medicine treatment on Herniated InterVertebral Disc (HIVD) of lumbar spine patient diagnosed by Magnetic Resonance Imaging (MRI). Methods This study includes 41 patients whose Lumbar Disc Herniations were by MRIbetween 1st Aprill 2011 and 31th March 2016. All of the patients were treated with Megadose Pharmacoacupuncture combined with Korean medicine treatment. The MRI examination was performed on two or more occasions (minimally, pre-treatment and post-treatment). The volume of each herniated disc was measured. For each patient, age, sex, disc migration, morphology, initial LDH size, herniated disc resorption rate were analysed. Results The mean volumes of herniated discs at pre-treatment and post-treatment were $1321.62{\pm}467.53mm^3$ and $648.72{\pm}313.38mm^3$. The volumes of all patients were decreased. The resorption means of each class of the extent of LDH were significantly different (p=0.041). On the other hand, no difference was found in sex, age, level, herniated disc grade. Conclusions The MRI results suggest that Megadose Pharmacoacupuncture combined with Korean medicine treatment can help treat lumbar herniated disc.
