Developing and Evaluating an Online Post-Traumatic Growth Program for Firefighters.

We evaluated how an online post-traumatic growth program affected rumination, social support, and post-traumatic growth. We recruited 33 firefighters from two Korean provinces and employed a nonequivalent control group pretest-post-test design. We administered the pretest for the intervention group (n = 16), consisting of eight sessions with an online workbook and messenger group counseling. We conducted post-tests immediately after the program and 4 weeks later. Post-traumatic growth and social support increased significantly. There were no statistically significant differences for intrusive or deliberate rumination. Psychological support programs should be developed to reflect firefighters' work characteristics and needs, including programs designed to induce rumination.

Cytological Study of Cypripedium japonicum Thunb. (Orchidaceae Juss.): An Endangered Species from Korea.

Changes in chromosome number and karyotype evolution are important to plant diversification, as they are both major drivers of speciation processes. Herein, chromosome number, karyotype, and genome size of the Korean lady's slipper orchid Cypripedium japonicum Thunb., an endangered species, were investigated in natural populations. Furthermore, all cytological data from this species are reported herein for the first time. The chromosome number of all investigated C. japonicum plants was diploid (2n = 2x = 22), with x = 11 as base chromosome number, whereby the species can now be clearly distinguished from the Japanese lady's slipper orchid. The karyotypes of all studied individuals were of similar length, symmetrical, and rather unimodal. Flow cytometry of the C. japonicum revealed that the genome size ranged from 28.38 to 30.14 pg/1C. Data on chromosome number and karyotypes were largely consistent with previous results indicating that Korean (x = 11) populations of C. japonicum are more closely related to Chinese populations (x = 11) compared to Japanese (x = 10) populations. These comprehensive cytological results will benefit the efforts to discriminate the geographically isolated and endangered Eastern Asian (China, Japan, and Korea) lady's slipper orchid species.

Application and Developmental Strategies for Community-Based Injury Prevention Programs of the International Safe Communities Movement in Korea.

PURPOSE: Safety of humans is an important factor that affects health overall, and injuries are one of the major public-health problems in the world. The purposes of this study were to describe the International safe Community movement which contributes to the injury prevention and safety promotion all over the world, and to identify out the application and developmental strategies for Korea. METHODS: A review was done of previous research, reviews, and reports on the history, concepts, basic principles, and recommendations for actions of the Safe Community. RESULTS: For this study, the application strategies of the International Safe Community movement in Korea were examined to deduce the strengths of the safe Community program. Community-based injury prevention work according to the International Safe Community model is a successful and cost-effective way of reducing injuries in the community. CONCLUSION: Through the International Safe Community program, communities are able to realize a healthy community and achieve improved quality of lives for the people, which is the ultimate objective of the Safe Community model. In addition, it will contribute to the economic vitalization and gain through energy and enhancement of productivity of people.
