New types of fire accidents appear or the existing types disappeared because of rapidly changing society. We proposed a methodology of extracting new nouns from fire investigation data each of which is an accident report producted by fire investigators. The new nouns could be used in modifying the existing categories for classifying fire accidents. We analysed morphology of the product names and the ignition summaries using the proposed method for the fire accidents classified as the etc sub-category of the category of equipments involved in ignition. In this paper, we found "dryer" as a new sub-category of the agricultural equipment category and "boiler" in the seasonal appliance category from the product names of the fire accidents. We also extracted the new input keywords of "aquarium" and "monitor" in the commercial facilities category and the video, audio apparatus category from the ignition summaries respectively. Using the four subcategories, we reclassified 548 (14.39%) of 3,808 fire accidents assigned to the etc sub-category.

This research aimed to identify walking trails' purpose of its use and the factors that influence the selection. For this, a survey targeting the walking trail users was conducted in 2016 to question the research aim stated above. The mean number of walking trail usage in a month was 2.51 times and the duration of use ranged from one to ten hours, with the average of 2.5 hours. The main reason for the usage was to maintain physical health and the following was for mental relaxation, thus showing more than 90% of the people concerned with physical and mental health. Walking trails near the residences had the greatest percentage and trails that include mountains, rivers, seas and lakes were the following. Trails near historical locations or countryside showed a lower percentage. The choices showed relevance to the proximity as a standard of selection. The next highest percentage was the convenience of transportation. Additionally, people that access the trails three or more times were inclined to be influenced by the installation of exercising equipment. The aspect of facilities showed that the place for relaxation was a significant selection factor such as bathrooms for 20s to 30s and exercising equipments for people older than 50. To access the walking trails, people reach it by automobiles, public transport, walking and bicycles and out of these, automobiles had the highest percentage.

Purpose: This study aimed to evaluate the current status of hospice palliative care facilities in Korea. Based on the result, we attempted to suggest activation plans of hospice palliative in Korea. Methods: To conduct a survey, we obtained a list of hospice palliative care facilities from related agencies and academic societies. A survey was conducted from February, 2009 to March, 2009. The survey was consisted of general characteristics of organizations, manpower, facilities & equipments, and so on. In addition, we used data from Statistics Korea to estimate the number of beds required and the bed occupancy rate. Results: Total number of facilities responded to the questionnaire were 53. Forty-two facilities were general hospitals and 6 facilities were clinics among the total 53 facilities, and 18.8% of facilities were located in Seoul, Incheon and Gyeonggido. Overall bed occupancy rate was rather low as 21.9%, and there were 4 provinces where bed occupancy rates were 0%. Deaths in hospice palliative care facilities during 2008 were 6.3% of total deaths from cancers. As for the questions about the financial status of facilities, 86% of facilities were answered financial insufficiency. Also more than half of the facilities gave financial insufficiency as the reason for shortage of human resource supplies and inability to achieve the standard for authorization by the government. Facilities answered in order to activate the hospice palliative care, governmental support is needed, mostly in financial support (71.2%), donation tax deduction (43.1%), and setting up a public utility foundation (23.5%). Conclusion: This study showed low rates of hospice palliative care use and bed occupancy in Korea. Regional variance in bed occupancy rate was significantly high. As a roadblock for these problems, most of the facilities cited financial insufficiency. Therefore, there must be some action plans to boost financial support to activate hospice palliative care in Korea. Finally, efforts to improve these circumstances including lack of understanding about hospice and palliative care, are needed as well.

With the government's support using new and renewable energy, photovoltaic equipment has been rapidly supplied. However, compared to supply rate, maintenance has not supported enough and relevant research has not much conducted. Even though large power plant facilities have been maintained well, small equipment for detached houses has been rarely maintained. Therefore, the purpose of this study is to analyze maintenance effectiveness of photovoltaic equipment for detached houses. It was analyzed that photovoltaic equipments were merely maintained. What is the most important in maintenance effectiveness is increase of power generation. It was estimated that if photovoltaic equipment for detached houses is maintained well, power generation increases by 6.5% at least. That produces the same effect as the additional supply of photovoltaic equipment to 9,700 households. As a result, it is necessary to maximize the effectiveness of the government's budget investment through well maintenance of photovoltaic equipments.

Nowadays, to prevent electrical accidents in Korea, inspectors directly performed checking general electrical facilities as a cycle from every one to three years. It is difficult to presuppose an omen because intact conditions of electrical equipments are not kept at the time of inspection. In this paper, in order to ensure effectiveness of an online basis electric inspection, we developed an electrical safety IoT system using LoRa communication technology to enable monitoring mainly electrical safety components such as overcurrent, overvoltage, resistive leakage current, and power. Then we proposed a method for verifying performances of the prosed electrical safety IoT system. Resistive leakage currents are calculated by using difference of phase between voltages and currents. We verified that average errors are 0.97%, which reference goal is ${\pm}5%$ for a device, through reliability test according to conditions. Results of this research can be used as basic study materials to develop technologies for measuring three phase leakage current and for implementing public electrical safety. platform.
