This study aimed to compare fear and prevention behaviors on accidents between mothers and teachers in family childcare centers. The participants were 117 mothers whose children were 0~2 year-olds and 121 teachers. Based on Hendrickson(2008) and Reichert & Henricks(1996), the scale was developed by the researcher, and it was composed of fear and prevention behaviors on accident. The data were analyzed using descriptive statistics and $x^2$ analysis. Results showed that mothers feared fall accidents and step-on-accidents while teachers feared suffocation accidents and liability for injury medical fee. Also, mothers did more prevention behaviors on use of car seats than teachers, whereas teachers did more behaviors on walk safety, custody of drugs and dangerous articles, and food safety.

The aim of this study was comparing measuring tools for detecting physical comfortness with variation of garment pressure. The measuring tools for detecting physical comfortness were EEG and survey questionnaire. Two low-pressure compressionwears and a commercial compressionwear (girdle) were tested. Results showed that the questionnaire survey well detected suffocation or motion comfortness. But it did not discrete the appropriate tightness of the compressionwears. The results of EEG analysis show that the absolute power of ${\alpha}$-wave value was elevated with the low-pressure compressionwears. It also showed lower stress value. The high-pressure compressionwear presented decreased absolute power of ${\alpha}$-wave value. It showed higher stress value. These results implicate that EEG can appropriatly indicate the change of physical comfortness of compressionwear. The appropriate tightness of compressionwear can be measured with EEG analysis rather than survey questionnaire.

Lately, In case of domestic fire situation, Suffocation due to inflammables has shown higher than direct disaster of the fire among the statistics of death caused by disaster. According to study, Lightweight Hybrid Panel as using the inner or outer wall is made with Polysilicon of the inorganic material, PA and vermiculite, so we make progress to performance experiment and review the density, thermal conductivity properties.

Differentiated thyroid carcinoma is a slow growing tumor with relative good prognosis. But locally advanced thyroid cancer with T4 or N1b is difficult to manage. Between June 1988 and April 1995, we resected 8 advanced thyroid cancers trans-sternally. All patients had direct mediastinal extension [T4 or mediastinal lymph node metastasis [N1b with airway obstruction or dysphagia. We operated all the patients by partial or total sternotomy for mediastinal dissection along with thyroidectomy and radical neck dissection. There were some acceptable morbidities but no operative mortality. Postoperative radioactive iodine therapy was followed without side effects. Follow-up survival period was between 11 months to 81 months with 2 late mortalities [17 month, 30 month . Although definite benefit for routine mediastinal dissection in thyroid cancer has not been established, in locally advanced cases impending airway obstruction or dysphagia who have questionable effect by radioactive iodine therapy alone, aggressive mediastinal mass dissection including lymph node metastasis has the significant role to prevent the patients from suffocation & dysphagia, and to enhance the effect of followed radioactive iodine tharapy.

The death from suffocation due to the gas from various disaster is frequent very and it occurs. Specially only from the company which treats the gas and only the enterprise which maintains the gas the many greeting accident occurs. Also accidents could occur when working around the toxic gas without one's noticing Therefore a development of the portable gas ditectoror is very essential. Specially with development of design and the new product of the electric chemical sensor might help reducing the many accidents. From the side which protects a worker's life, it isn't just simple equipment but also it must be connected directly to life saving is very important. Therefore, the key technical contents of development must be focused on sensor which is simple and easy to carry and able to detect varieties of toxic gas. So, this study is about the product design which is simple and easy to carry and to use.

In This study, we tried to review an efficient curing method in consideration of safety and constructability among the problems of winter construction. In other words, as a result of the mock-up test, the measured value of carbon monoxide was 0 ppm in the case of an electric hot air fan. Since there is no carbon monoxide, problems such as suffocation are expected to be solved. In terms of temperature characteristics, electric hot air fans exhibited high thermal efficiency performance with a slight difference in upper/lower temperatures compared to the existing ones. In the future, we plan to conduct thermal efficiency evaluation through actual site performance verification. We will propose an efficient curing method through applicability evaluation.

Recently, the need to strengthen the Air Environment Conservation Act and secure alternative heat sources during the winter by carbon neutrality policies has been raised. Accordingly, winter construction, which has safety and quality measures, is emerging as an essential factor. It is believed that eco-friendly tropical type electric hot air heaters will be able to solve most of the problems of winter construction at construction sites, especially prevention of suffocation and fire accidents. In addition, as a result of on-site performance verification, it has secured more than the same performance as the existing curing method, and the curing technology can create an eco-friendly and pleasant working environment while considering safety and construction.

Domestic building finishing materials are being evaluated according to KS F 2271 standards according to the notification of the Ministry of Land, Infrastructure and Transport, and this test is evaluated using laboratory animals. In this study, experiments were conducted on highly combustible organic insulation materials such as EPS, urethane, and phenolic foam. The purpose of this study was to analyze the cause of the behavioral suspension of the experimental mice by measuring the average behavioral suspension time of the mice caused by the harmful gas generated when these three types of insulation materials were burned. FTIR analysis and smoke density experiment were performed as a cause analysis method for the behavioral suspension of mice, and the experimental results were analyzed by dividing the causes of behavioral suspension into suffocation by particulate matter and toxic inhalation by gaseous substances. As a result of the test, urethane was evaluated as the most harmful insulation material, and as a result of FTIR analysis and smoke density test as a cause analysis for the gas toxicity test results, it is judged that the behavioral stop of the rats by suffocation is higher than the effect of toxic inhalation. This study is a basic study on the cause analysis of harmful gases, and it will be necessary to prepare the toxicity basis and analyze various materials and gases.

Nitrogen is an inert gas that is harmless to humans under normal conditions. While it is not inherently toxic, nitrogen gas becomes dangerous when it displaces oxygen, resulting in suffocation. Herein, we report a case of a 34-year-old man who attempted suicide by nitrogen asphyxiation who presenting with decreased mental function and agitation. Lactic acidosis and hyperammonemia were observed on presentation at the emergency department, but these improved after a few hours. After 2 days, the patient regained full consciousness, and was discharged without any complications. Survival after asphyxiation due to nitrogen gas is very rare, and these patients are more likely to have poorer outcomes. There is a potential for the increasing use of nitrogen gas as a method of committing suicide because of the ease of access to this gas.
