The aim of this study was to investigate the sun protection use behaviour among university students from 25 low, middle income and emerging economy countries. Using anonymous questionnaires, data were collected from 18,687 undergraduate university students aged 18-30 years (mean age 20.8, SD=2.8) from 26 universities in 25 countries across Asia, Africa and the Americas. Overall, 57.2% of university students reported liking to sunbathe and of those only 48.1% used sun protection when sunbathing. In multivariate logistic regression, younger age, being female, coming from a wealthy or quite well off economic family background, living in an upper middle or high income country, lighter skin tone, and other health behaviours were found to be associated with sun protection use behaviour. Low sun protection use calls for health promotion programmes to prevent unprotected sun exposure.

The purpose of this study was to provide basic data for developing effective forest healing programs for retirees by identifying their characteristics and preferences. A survey was conducted on demographic characteristics, overall perceptions of forest healing, and preferences for forest healing programs, targeting a total of 258 retirees visiting a natural recreation forest and a healing forest. The results of the survey suggested that the awareness of the forest treatment program and the hope of participating in it were both high, but the experience of participating in the program was low. Among the forest healing programs, the order of preference was "Breath in the forest", "Wind bathing and sunbathing", and "Feeling negative ions in the valley". Based on these results, it is expected that the forest healing program for retirees will be used as basic data for development of such programs in the future.

This study is about a service that allows people to naturally learn to bask in the sun, which is a habit to relieve depression. Modern people do not have enough time to bask in the sun due to their busy lives, and as a result, depression and fatigue are increasing day by day. Therefore, in order to relieve depression, there is a need for the development of technology to manage the schedule of sunlight basking so that users can experience sunlight more naturally. The sunlight service developed through this study can help you easily plan your sunlight schedule by recommending good dates, times, and locations for sunbathing. In addition, users can receive coins as much as they bask in the sun, and they can be motivated by the act of basking in the sun by raising their character with those coins.

In this research, a habitat model for Chinemys reevesii is suggested based on the components and variables of the Habitat Suitability Index which was determined through a series of literature researches, site surveys, and behavioral analysis. After reviewing the general habitat requirements, the site surveys(9 reservoirs) from July to December 2010, and the behavioral analysis of five Chinemys reevesii, the relationship between the behavioral and habitat use pattern was evaluated. According to the site surveys and behavioral analysis, the ecological core area(FK 50%) was about 0.96ha on average, the influence area(FK 90%) 4.22ha, and the home range was about $37.75{\pm}17.26m$ on average. As for the habitat use pattern of Chinemys reevesii, it travels through canals, and is influenced by the surrounding land uses. Also when there is a lack of food, the home range increases, and during hibernation, Chinemys reevesii prefers to be in an area within 1~2m range of water shores of fine textured soil and aquatic plants. After analyzing the information, the HSI standard was set and its components were determined as food, sunbathing and cover, aquatic environment, and spatial relationships. And the variables and the ranges of the components was determined as aquatic plant cover(0~49.81%), sandy area($3{\sim}13m^2$) and water velocity(0~60cm/s) etc. Lastly, plans and sections of the habitat model is provided designed according to the information from the researches, and problems to consider during habitat restoration was suggested in order to help understand about Chinemys reevesii habitat.

Background: Skin self-examination (SSE) may facilitate early diagnosis of melanoma at a potentially curable stage. Little data are available concerning the SSE frequency and knowledge about the symptoms of melanoma in non-patient populations. The aim of our study was to assess the performance of skin self-examination, recognition of potential melanoma symptoms as well as behavior related to sun exposure among web users in Poland. Materials and Methods: A cross-sectional study was conducted among readers of a scientific portal. Invited respondents were asked to complete an online questionnaire. Finally, statistical analysis was conducted on 4,919 surveys towards potential clinical signs of melanoma and SSE performance. Results: Approximately 60% of respondents had ever performed SSE in their life. Only 18.4 % declared performance on a regular, monthly, basis. Factors promoting this activity were established to be bigger place of residence, higher education and sensitive skin phototype, higher level of knowledge concerning melanoma, safe tanning rules and, especially, past surgical excision of naevi. Declared longer use of tanning beds was linked to understanding better the importance of clinical features of melanoma. Awareness of hazardous behavior during sunbathing is associated with the attempts to change them. Conclusions: Regular SSE is not a common practice, whilst the knowledge about the clinical features of melanoma is varied. Therefore, constant pressure should be put on promotion of regular skin self-examination and teaching its proper techniques, including familiarity with the ABCD (asymmetry; border; color; diameter) rule and its extension of "EFG" (elevated, firm, progressive growth) criteria.

On May 27, 2019, a non-native turtle was discovered at Ilsan Lake Park, Janghang-dong, Ilsandong-gu, Goyang-si, Republic of Korea. The turtle was identified as a western painted turtle (Emydidae: Chrysemys picta bellii) based on the external morphology, plastron color, plastron pattern, stripes on the side of the head, and shape of the carapace. In the lake park, another non-native turtle was observed sunbathing on the same rock. In this paper, we firstly reported the confirmed presence of a western painted turtle in the wild of Korea. Unfortunately, various non-native turtles are continuously reported in Korean ecosystems. Therefore, we highlight that continuous surveying and reporting of the non-native species is important to their management.

When conducting risk assessments of cosmetic ingredients, it is important that reliable exposure information is obtained for cosmetic products. As cosmetics are becoming more diverse, continuous effort must be made to obtain exposure data that reflect their growth and usage trends. The usage pattern of cosmetics, such as the application area and amount used, may differ by product type and also by country. We conducted a survey to compare the amount of sun spray and sun cream used in a usage environment in South Korea. The study was conducted on Haeundae Beach, one of the most popular beaches in South Korea. A total of 1,255 beachgoers participated in this study; 604 and 651 participants used the sun spray and sun cream, respectively, while sunbathing and enjoying water activities on the beach for one day. Exposure was analyzed following a probabilistic method. On comparing all subjects, it was found that the group that used sun spray (mean: 44.52 g/day) used significantly more product (p = 0.000) than those who used sun cream (mean: 20.51 g/day). By analyzing the daily exposure of sun spray and sun cream per unit body weight according to age and gender, the exposure amount of sun spray and sun cream was found to be highest among 2~9 year-old girls (mean for sun spray: 2.51 g/kg/day, p95: 5.50 g/kg/day, mean for sun cream: 0.79 g/kg/day, p95: 1.79 g/kg/day). The amount of sun spray used is approximately twice that of sun cream. Among both the sun spray and sun cream groups, the exposure amount per unit body weight was highest in girls younger than 10. These factors should be considered when conducting risk assessments of sun spray and sun cream.

This study aimed to analyze the preference of subfertile women for forest therapy programs depending on their emotional characteristics, and to provide basic data for the development of forest therapy programs in order to promote the mental health of subfertile women. Among the surveyed emotional characteristics of subfertile women, the level of emotions including pressure to become pregnant, impatience and frustration were high, while that of emotions including anxiety and fear; depression, hopelessness, helplessness, loneliness and sadness tended to be medium. The level of emotions including shame and guilt tended to be low. The top six forest therapy programs preferred by subfertile women include a deep breath of air /phytoncide, forest bathing/wind bathing/sun bathing, self-esteem recovery program, eating organic foods, low body bathing/foot bathing/hot spring bathing, and breathing/breathing exercises. Subfertile women highly pressured to become pregnant showed significant differences in the preference of the self-esteem recovery program, Domar 's relaxation therapy, NLP therapy, and sleeping in the woods, while women with anxiety and fear showed significant differences in the preference of walking barefoot in forests, mountain walking in silence, listening to water sounds/ hand and foot soak, self-esteem recovery program, NLP therapy, cognitive behavior therapy, aroma therapy, integrated art therapy in forests, forest bathing/wind bathing/sunbathing, a deep breath of air/phytoncide, and observing stars. Women with depression, hopelessness, helplessness, loneliness, and sadness showed significant differences in eating organic foods, self-esteem recovery program, counseling/coaching, and cognitive behavior therapy. The significance of this study was to analyze the preference of subfertile women, as subjects, for forest therapy program. The results of this study are expected to be used as basis data for developing forest therapy programs for subfertile women.

The purpose of this study is to identify the home range and habitat using pattern of the native species, Mauremys reevesii, and the exotic species, Trachemys scripta elegans, and to analyze the mutual competition relationship of the two species. This study was conducted at the Goldfish square pond, which is located in the upper part of the valley of Cheonggye mountain from August 2, 2010 to January 30, 2011. We used the three artificially proliferating M. reevesii and three T. scripta elegans which were inhabited in the ponds and reservoirs for monitoring study after attaching the transmitter to each of them. We measured the home range and the habitat utilization radius of three individuals of each species and the environmental factors such as temperature, humidity and soil and water temperature around the Goldfish square pond. As our results, it was analyzed that the M. reevesii and T. scripta elegans have a redundant ecological positions in various aspects such as limited sunbathing places, food resource utilization, hibernation place, etc. We also found that the relatively small M. reevesii was being pushed out of the competition by the relatively big. Further investigation of food competition and habitat utilization should be necessary for these two species for the natural habitats, their home range, food competition, and habitat utilization. The result of this study will be the basic data M. reevesii's restoration project.
