Although the recent interest in and favor for natural burial has increased, there are still few who choose it as a funeral. The purpose of the study is to supply necessary information to promote the choice of natural burial. For this a survey of 430 students and residents was conducted in Daejeon. The result of the research is as follows. First, there is a significant difference in use intention of natural burial by age and religion. People under the age of 30 and Catholic believers recorded the highest score in use intention of natural burial. Second, there was a significant difference in information on natural burial by age or religion, in religion and philosophy by age, in physical environment by sex or age, and in conservation by sex or age. In general, the lower the age, the higher the positive perception of natural burial was. While females had a more positive perception of physical environment than males, males had a more positive perception of conservation than females. All sub factors of the perception of natural burial such as information on natural burial, funeral style, religion and philosophy, physical environment and conservation had a significant and positive effect on its use intention. However, ratio skew showed that religion and philosophy had the strongest effect on use intention of natural burial, followed by funeral style, physical environment, conservation, and information on natural burial.

The choice of business method is a necessary decision at the last moment of life, and to this end, we use several criteria. Our funeral methods were dominated by ancestral worship culture and religion, not nature. It is only recently that nature was used as a means from a human perspective, but natural field methods such as consideration for nature and symbiosis with nature have emerged. The recent high public preference for natural fields is today's strong zeitgeist and nature-friendly values. Based on statistics in 2021, Korea's national cremation rate exceeded 92%, and compared to less than 20% of the cremation rate just 20 years ago, our business method has changed rapidly. As the cremation promotion movement and government policies, which began in the early 90s, were systematically developed, the enshrinement facility was established next to us. However, while this was also subject to criticism of national damage, the Jang Act called natural field was introduced into the system in 2008, and about 15 years have passed, but the revitalization of natural field is slower than expected. One of the reasons for the stagnation of development is to forget the basic spirit of the natural field (once you return to the forest), and to think like a graveyard grave. Accordingly, this study aims to identify the background of the introduction and current operation of natural fields and present development measures to improve memorial services to make natural fields loved by the people.

Natural ventilation in radioactive waste repositories is considered to be less efficient than mechanically forced ventilation for the repository working environment and hygiene & safety of the public at large, for example, controlling the exposure of airborne radioactive particulate matter. It is, however, considered to play an important role and may be fairly efficient for maintaining environmental conditions of the repository over the duration of its lifetime, for example, moisture content and radon (Rn) gas elimination in repository. This paper describes the feasibility of using natural ventilation which can be generated in the repository itself, depending on the conditions of the natural environment during the periods of repository construction and operation. Evidences from natural cave analogues, actual measurements of natural ventilation pressures in mountain traffic tunnels with vertical shafts, and calculations of airflow rates with given natural ventilation pressures indicate possible benefits from passive ventilation for the prospective Korean radioactive waste repository. Natural ventilation may provide engineers with a cost-efficient method for heat and moisture transfer, and radon (Rn) gas elimination in a radioactive waste repository. The overall thermal performance of the repository may be improved. The dry-out period may be extended, and the seepage flux likely would be decreased.

This study predicted temperature in the disposal tunnels using computational fluid dynamics based on natural ventilation quantity that comes from high altitude and temperature differences that are the characteristics of high level waste repository. The result of the previous study that evaluated quantitatively natural ventilation quantity using a hydrostatic method and CFD shows that significant natural ventilation quantity is generated. From the result, this study performed the prediction of temperature in disposal tunnels by natural ventilation quantity by the caloric values of the wastes, at both deep geological repository and surface repository. The result of analysis shows that deep geological repository is effective for thermal control in the disposal tunnels due to heat transfer to rock and the generation of sufficient natural ventilation quantity, while surface repository was detrimental to thermal control, because surface repository was strongly affected by external temperature, and could not generate sufficient natural ventilation quantity. Moreover, this study found that in the case of deep geological repository with a depth of 200 m, the heatof about $10^{\circ}C$ was transferred to the depth of 500 m. Thus, it is considered that if the high level waste repository scheduled to be built in the country is designed placing an emphasis on thermal control, deep geological repository rather than surface repository is more appropriate.

The purpose of this study is to identify determinants for preferred funeral methods depending on socio-economic characteristics. In South Korea, the Act on Funeral Services, Etc. categorizes funeral methods into burial, inurnment, and natural burial. This study empirically analyzes how and what socio-economic characteristics affect choices among these three categories. Data is collected from Social Survey 2017 and funeral facilities in the country. The data to be analyzed is developed in terms of a hierarchy which puts the burial and cremation methods in an upper class and the inurnment and natural burial methods in a lower class. Based on this data, a nested logit model is employed to conduct empirical analysis. The analysis indicates that those characteristics that have a statistically significant influence on preferred methods include gender, age, householder, marriage, satisfaction with life, class awareness, monthly income, housing type, housing tenure type, and living in city area. Each variable's modulus of calculated direct and cross elasticity need to be used to analyze the outcome of a nested logit model. In this study, the modulus of direct and cross elasticity are determined for the significant variables. The calculated direct elasticity is applied to analyze the likelihood of choosing each funeral method when there are changes in the significant variables. When a particular method has been selected, on the other hand, the cross elasticity is utilized to analyze changes to the likelihood of choosing the other methods. One of the most notable results is related to natural burial. In order to meet the demand for natural burial, it is necessary to provide more burial sites and raise awareness of natural burial. This will facilitate the efficient use of national territorial space.

Purpose: As corn oil is semi-drying oil, it has more double bonds than non-drying oil and is easier to combine with oxygen. In addition, among the causes of spontaneous ignition, accidents caused by oil-soaked cloths due to oxidative heat are gradually increasing. Therefore, the purpose of this study is to understand the characteristics of spontaneous combustion according to the number of towels and the amount of corn oil at 65℃. Method: After setting the test temperature to 65℃, 25ml, 50ml, 75ml of corn oil per towel was sprayed. The central temperature of the sample rises above the set temperature. It was determined, and when the central temperature of the sample became similar to the set temperature, it was determined as non-igniting. Result: After evenly distributing 25ml of corn oil per towel, as a result of the experiment, 5 towels did not ignite, and 10 and 15 towels ignited. Also, as a result of an experiment using 50ml and 75ml of corn oil per towel, spontaneous ignition occurred when the number of towels was 5, 10, or 15 sheets. Conclusion: Even a small amount can cause a fire if the conditions for spontaneous ignition are met.

현대에는 다양한 조명기구들로 불이 흔한 시대가 되었지만, 예전에는 불이 귀해 자연에서 얻은 재료로 불을 밝히곤 하였다. 자연에서 나와 다시 자연으로 돌아가면서 불을 밝혔던 고콜불과 등경돌을 돌아보며 '불' 의 의미에 대해 다시금 생각해 볼 일이다.

The number of campers has been consistently growing thanks to the introduction of a five-day work week and the time increase for a leisure. Thus, many types of facilities for camping are constructed. For instance, there are gravel camp site, which is called crushed stone, and normal soil camp site in case of private camp sites. The amount of natural background radiation, measured from site to site, was analyzed. The value of soil camp site was lower than that of crushed stone camp site. And the amount of natural background radiation from normal camp site was also lower than that from the artificial shade made by tarp. Consequently, it is noted that normal soil camp site with the plenty of woods should be chosen for camping place in order to avoid natural background radiation.
