This study was carried out to investigate the insect fauna of the Seobyeok-ri area, the foot og Mt. Musu, Bonghwa-gun, Gyeongbuk for obtaining basic entomological data related to changes in the region's insect fauna and to secure forest insect resources. The study area is highly important in terms of biodiversity and preservation. Therefore, it can be said that the area requires basic data for studies on vulnerable species related to future climate changes and changes in insect distribution. The study was conducted between May and September, from spring to autumn, and insect specimen were collected and identified. A total of 6 orders, 52 families, 380 species and 3,030 individuals of insects were collected during the study. Furthermore, in terms of important dominant species confirmed during the study, Macaria liturata (Clerck) was observed the most frequently during May with 23 individuals, Arichanna melanaria (Linnaeus) during June, Macaria liturata (Clerck) during July, Axylia putris (Linnaeus) during August and Spilonota eremitana Moriuti during September respectively.

A wireless sensor network (WSN) consists of several sensor nodes and usually one base station. In this paper, we propose a method to monitor topics using a wireless sensor network. Fire threatens people, animals, and plants, and it takes a lot of recovery time when a fire occurs. For this reason, it is necessary to use a fire monitoring system that is easy to configure and fast to avoid fire. In this paper, we propose a fast and easily reliable fire detection system using WSN. The wireless node of the WSN measures the temperature and brightness around the node. The measured information is transferred to the workstation and to the base station. The workstation analyzes current and historical data records to monitor the fire and notify the manager.

Background: Human skin is exposed to various environmental stresses, such as heat, cold, and ultraviolet (UV) radiation. Heat shock proteins (HSPs) induced by temperature elevations, as a physiologic response to mediate repair mechanisms and reduce cellular damage. Objective: The purpose of this study was to investigate the induction of HSPs in human skin cells after UV exposure. Methods: We performed immunoblotting using a specific monoclonal antibody to the HSP70 family, one of the best-conserved stress proteins in humans, with cultured normal human keratinocytes, A431 cells, human melanocytes, SK30 cells, and human dermal fibroblasts (HDF). Results: Our results indicated that high expression of HSP70 in the unstressed state was noted in epidermal cells, including normal human keratinocytes, A431 cells, human melanocytes, and SK30 cells, but epidermal cells showed no additional up-regulation of HSP70 after UV irradiation. On the other hand, HDF expressed very small amounts of HSP70 at baseline, but significantly higher amounts of HSP70 after UV exposure. Conclusion: These findings suggest that constitutive expression of HSP70 in epidermal cells may be an important mechanism for protection of the human epidermis from environmental stresses, such as sunlight exposure.
