The purpose of this study was to identify the effectiveness of concepts on global warming, practical will and belief on global warming mitigation by experiments based on global warming program. For this study, 60 $6^{th}$ grade students were selected in two elementary schools. They were divided into an experimental group and a control group. The students of the experimental group took part in global warming program focusing experiments for 10 lessons during 2 weeks. The students of the control group were taught according to the regular curriculum of $6^{th}$ grade about global warming. To identify the effects of this program, both groups' students were tested on concepts on global warming, practical will and belief on global warming mitigation before and after the program implementation. Also the students of the experimental group wrote an essay and gave an interview about the program after implementation. The results were that the experimental group gained higher scores than the control group in the concepts on global warming. The programs improved students' practical will and belief on global warming mitigation. Also this program showed that the students systematically understood on global warming than existing classes in the regular curriculum.

Purpose : This study investigated the effects of active warming using a Warm Touch warming system or a cotton blanket in postoperative patients after general anesthesia for abdominal surgery. Methods : This quasi-experimental study utilized two experimental groups and one control group: a cotton-blanket group (n = 25) were warmed with a cotton blanket and a sheet; a forced-air warming group (n = 24) were warmed with a Warm Touch warming system, a cotton blanket, and a sheet; and a control group (n = 25) were warmed with a sheet. Measurement variables were postoperative pain, body temperature, and thermal discomfort. Data were analyzed using a one-way ANOVA, ${\chi}^2-tests$, Fisher's exact test, and a repeated measures ANOVA. Results : The effects of active warming using a Warm Touch warming system and a cotton blanket on postoperative patients was significant in reducing pain (F = 13.91, p < .001) and increasing body temperature (F = 12.49, p < .001). Conclusion : Active warming made a significant difference in pain and body temperature changes. Active warming methods may help patients' postoperative recovery and prevent complications. Further research is needed to explore the effects and side effects of active warming on recovering normothermia.

Purpose: The main question is systematic review of the published in Korea and foreign countries on warming therapy for surgical patients. Methods: The researchers searched at Medline, CINAHL, KERIS, Adult Nursing Association, Korean Society of Nursing Science, Korean Academy of fundamentals of Nursing, and National Assembly Library web site for the published on warming therapy for surgical patients from 1980 to 2008. Words for search were operation/surgery, warming, operation/surgery and warming. Studies were included randomized controlled trial, and there were no restrictions regarding operative phase and outcome measures. Results: 36 published researches that met the criteria were mostly published in foreign countries between 2000 and 2008 and focused on surgery with general anesthesia. Sample size ranged from 21 to 60 subjects, age range between 21 and 60 years of age. Thirty different warming therapies were reported, fifty-two different dependent variables. Outcome indicators included active external warming, intra-operative, and body temperature. 'Positive effects' and 'no effects' equaled. The most frequently reported 'positive effects' were body temperature, shivering, and acid-base balance. No effects were more likely to be heart rate, blood pressure, and hemodynamics. Conclusion: Many types of warming therapy, are reported in the literature with little information about the efficacy of each, many different dependant variables were studied. There were no consistent reports as to length of time used for warming procedures. Overall, the effects of warming therapy are inconsistent. And additional research must be down before any particular method of warming can be used with confidence as to its effectiveness. Attention must be made as to the research design, better measurement of the dependent variables. This review may serve as a base.

Lack of sleep time increases risks of fatigue, hypomnesis, decreased emotional stability, indigestion, and dementia. The risks can be reduced by providing eyelid-warming, inducing sleep and improving sleep quality. However, effective warming temperature to an person varies depending on physical condition and the individual. The various types of frequencies can be identified in brain wave from a person and amount of frequencies is also changed continuously before and after sleep. Therefore we can identify the user's sleep stage with brain wave, namely EEG. Effective sleep induction is possible if warming temperature to a person is controlled based on EEG. In this paper, we propose customized warming control techniques based on EEG for a efficient and effective sleep induction. As an experiment, sleep induction effects of standard sleep mask and customized temperature control techniques sleep mask are compared. EEG data and warming temperature were measured in 100 experiments. At customized warming control techniques, experiments showed that the ratio of alpha and theta waves increased by 3.21%p and the time to sleep decreased by 85 seconds. It will contribute to effective sleep induction and performance verification methods in customized sleep mask systems.

Objectives : The objective of this review was to evaluate clinical trials of warming acupuncture for musculoskeletal pain diseases, to assess the methodologic quality of the trials and determine whether low-quality trials are associated with positive outcomes, to document adverse effects and to identify the effectiveness of the warming acupuncture. Methods : Seven databases and the Journal ZHONGGUO ZHENJIU(中國鍼灸) published between 2004－2008 were searched. Korean and Chinese randomized trials were evaluated for methodologic quality using the modified Jadad scale. Outcome measurements were pain, function and global improvement. The best-evidence synthesis was performed to determine the strength of evidence by control group. Results : Six clinical trials representing 564 patients with musculoskeletal pain diseases were identified. For pain and function, there was moderate evidence that warming acupuncture is more effective than manual acupuncture. For patient global assesment, there was limited evidence that warming acupuncture is more effective than manual acupuncture. However, for function, there was inconclusive evidence that warming acupuncture is more effective than acupuncture with TDP or western medicine or acupoint-injection treatment. Conclusions : The evidence suggests that warming acupuncture is more effective for musculoskeletal pain diseases than manual acupuncture, acupuncture with TDP, western medicine and acupoint-injection treatment. But the evidence is moderate to inclusive due to the low methodologic quality of the trials. Further clinical trials with high methodologic quality is required to investigate the effectiveness of warming acupuncture.

This study first investigates the changes of the mean and extreme temperatures and precipitation in East Asia (EA) under stabilized 1.5℃ and 2℃ warming conditions above preindustrial levels provided by HAPPI project. Here, five model with 925 members for 10-year historical period (2006~2015) and 1.5/2.0℃ future warming scenarios (2091~2100) have been used and monthly based data have been analyzed. The results show that the spatial distribution fields over EA and domain averaged variables in HAPPI 1.5/2.0℃ hindcast simulations are comparable to observations. It is found that the magnitude of mean temperature warming in EA and Korea is similar to the global mean, but for extreme temperatures local higher warming trend for minimum temperature is significant. In terms of precipitation, most subregion in EA will see more increased precipitation under 1.5/2.0℃ warming compared to the global mean. These attribute for probability density function of analyzed variables to get wider with increasing mean values in 1.5/2.0℃ warming conditions. As the result of vulnerability of 0.5℃ additional warming from 1.5 to 2.0℃, 0.5℃ additional warming contributes to the increases in extreme events and especially the impact over South Korea is slightly larger than EA. Therefore, limiting global warming by 0.5℃ can help avoid the increases in extreme temperature and precipitation events in terms of intensity and frequency.
