Purpose: The purpose of this study was to investigate the changes of stress and cumulative stress in 49 people and the changes of job stress, socio-psychological stress and anxiety relief levels by conducting a survey of 85 people after Gyorae forest bathing. Methods: The level of stress was measured using the uBioMacpa, and questionnaire was conducted to derive the data. Results: In the stress level after the forest bath, the control group showed no significant and the experimental group showed a significant decrease in the bathing (p<.043). In the cumulative stress change, the control group showed no significant difference after the bathing, but experimental group decreased significantly (p<.02), and in the variance analysis, there was a significant difference between the groups, and also between the group and the before and after tests (p<.002). In the questionnaire about job stress, there was no significant difference in physical environment and job demand. Overall, in the case of job stress, there was a significant decrease (p<.001). Job autonomy, relationship conflict, organizational unfairness, inadequate compensation, and workplace culture also had a significant decrease in stress (p<.001). The social psychological stress was significantly decreased after bathing (p<.001). The state anxiety decreased significantly (p<.001) after forest bathing. Conclusions: After the forest bathing in the Gyorae forest, the stress and anxiety are both reduced and significant, providing basic information that is very helpful as a natural healing place for stress relief.

This study aimed to systematically review the literature on the stress reduction of meaning-centered therapy (MCT) studies in Korea and to identify the characteristics of MCT for stress reduction. MCT studies aimed at reducing stress symptoms were searched among peer reviewed journal articles and unpublished dissertations until April, 2020. Two independent researchers assessed the risk of bias and the quality of the report using Scottish Intercollegiate Guidelines Network criteria. As a result of searching with 7 databases, 7 studies were finally selected. Seven MCTs were for all age groups, and 5 studies reported MCT was effective in reducing stress symptoms. Both single and combined type interventions were effective in reducing stress symptom, Researchers used the combined MCT more than single MCT program. The study with no significant effect was related to school test stress. There is a need to develop MCTs suitable for school-age youth with test stress in the future.

The purpose of the study is to prove the effectiveness of the bibliotherapy in decreasing the stress among the elderly. A 4-week program was developed and provided in 2 types, group meeting and individual telephone contact, for the old over 60 years. A total of 121 participants completed the program offered at 16 institutions. Participants' stress perception and stress response were measured prior to the bibliotherapy and post-tests were followed. 17 hypotheses were tested statistically by t-test and ANOVA. The followings are the main results. Both types of the bibliotherapy are effective in decreasing the stress of the old. Group meeting program is more effective than individual contact program. There were no significant effectiveness difference among the groups divided by sex, age, and education level. Bibliotherapy effectiveness is differ among groups divided by the initial stress perception level. Obviously, bibliotherapy was more effective for the old in high stress level than those in low stress level. Based on the results, recommendations are suggested to promote the bibliotherapy program.

본 연구는 청소년 스트레스 호르몬 변화를 보기위한 연구로 컬러 컨설팅 환경개선에 따른 스트레스 호르몬 변화를 연구하였다. 청소년 스트레스 연구들에 따르면, 아동이나 청소년도 성인만큼 스트레스를 경험하고 있고 청소년들의 스트레스는 정서적 부적응과 신체적 건강에도 영향을 미친다. 스트레스가 지속되면 부신피질에서 스테로이드 호르몬인 코티솔도 분비하는 근거를 통해 환경변화로 생긴 코티솔 분비를 측정하였다. 코티솔 분비를 통한 스트레스 반응 정도 측정은 침해성을 최소화하기 위한 간편한 방법인 타액검사로 실시하였으며 비 침습적인 방법으로 특별한 장비나 도움이 없이 수집할 수 있었고 부작용이 적은 효율적 검사였다. 연구 결과 전체 학생(46명)의 코티솔은 환경개선 사전($0.121{\pm}0.087{\mu}g/dL$)에 비해 사후($0.096{\pm}0.058{\mu}g/dL$)에 감소하였고(t=1.718, p=.093) 중고등학생(36명)의 코디솔은 사전($0.137{\pm}0.092{\mu}g/dL$)에 비해 사후($0.104{\pm}0.062{\mu}g/dL$)에 감소하였으며, 유의수준 10%에서 통계적으로도 유의미한 차이를 보였다(t=1.750, p=.089). 따라서 환경 개선 전에 비해 환경 개선 후 청소년들의 스트레스가 감소되었음을 알 수 있다. 하지만 초등학생(10명)의 코티솔은 사전($0.064{\pm}0.023{\mu}g/dL$)에 비해 사후($0.065{\pm}0.016{\mu}g/dL$)에 변화를 보이지 않아, 유의수준 5%에서 통계적으로 유의미한 변화는 나타나지 않았다(t=-0.121, p=0.906). 따라서 후두엽이 발달하는 중학생 시기는 환경 변화에 민감하며 색채 자극에 크게 영향을 미치는 시기인 만큼 본 연구에서 환경전후로 검사한 코티솔 분비의 측정값도 감소함을 볼 수 있었다. 하지만 본 연구는 환경 변화에 코티솔 분비량에 유의미한 변화를 나타내지 않은 초등학생들은 스트레스 호르몬 변화에는 차이가 없었지만 환경변화의 자극이 없었다고 볼 수는 없다.

This experiment was carried out to elucidate change of antioxidant enzymes activities subjected to water stresses in soybean plant. In this study, we measured the activities of ascorbate peroxidase(APDX), monodehydroascorbate reductase(MDHAR), dehydroascorbate reductase (DHAR), glutathione reductase(GR) subjected to drought or flooding stresses for 4days and following recovery for 3days. Leaves of two soybean lines subjected to drought or flooding showed premature senescence as evidenced by the decrease in water content and total soluble protein content but those of soybean leaves was increased when stresses were recovered for 3days. The activities of APDX and GR subjected to drought or flooding were the decrease but those of enzymes were recovered when water stress was recovered. The activities of MDHAR with drought or flooding were on the decrease, whereas those of DHAR were increased, respectively. Antioxidant contents decreased continually subjected to drought or flooding but it recovered after 3 days subjected to water stresses.

Background: A quasi-experimental study with non-equivalent control groups was performed to determine an effect of aromatherapy foot bath on stress and autonomic nervous activity. Methods: To confirm the effect of aromatherapy foot bath, aromatherapy foot bath group was asked to have a bathing by dropping 0.5 cc in 18 L water after blending with a ratio of 6:3:1 with essential oil lavender, lemon, and tea tree and a foot bath group was asked for bathing only by water. Results: Aromatherapy foot bath group showed significant decrease in subjective stress score (t=3.465, p=0.001) and stress index (t=3.021, p=0.004) in addition to simultaneous increase in sympathetic nervous activity (t=-2.913, p=0.005). However, no significant stimulation of parasympathetic nervous system was observed (t=-1.831, p=0.072). Conclusions: As aromatherapy foot bath is a possible effective intervention for stress relief, it can be applied as an effective method to relieve the stress for healthy adults and patients.

The aim of this study is to know how the rat submandibular gland changes under various emotional stress condition, using molecular biological methods. Restraint and chronic unpredictable mild stress (CUMS) experiment is conducted on fifty one 7-week old Sprague-Dawley rats (restraint stress experiment: 21, CUMS: 30). The rats were sacrificed, the submandibular glands were excised immediately at certain time, and examined by the use of immunohistochemistry and western blotting. In CUMS experiment, sucrose preference test, water intake change, weight change were implemented at 1 week interval for the experimental period The results are as follows: 1. The number of clusterin-secreting cells of restraint stress group compared to control group showed significantly decreasing tendency in all experimental groups except for the 1st hour group (p<0.001 in the 9th, 24th, 72nd, 120th, and 168th hour group). 2. The number of clusterin-secreting cells of CUMS group compared to control group showed significantly increasing tendency in the 2nd week group (p<0.01), and significantly decreasing tendency in the 4th and 5th week group (p<0.001). 3. Sucrose preference test in CUMS experiment showed significant difference between the 5th week experimental group and control group (p<0.01). 4. Weight change in CUMS experiment showed significant difference between the 5th week experimental group and control group (p<0.01), but water intake change didn't show significant difference compared to control group. 5. In western blot analysis, clusterin expression was decreased on a gradual basis in due time compared to the control group in the restraint stress group. As for CUMS group (chronic unpredictable mild stress group), it was increased till the 2nd week and decreased till the 5th week after that, which is similar to immunohistochemical analysis result and the decreasing tendency of sucrose preference and weigh changes. Through the test, it was proved that expression of clusterin in saliva glands decreases after receiving either acute or chronic stress, indicating relation with depression caused by chronic stress. Unlike other data, however, apoptotic tendency was hardly found in tissues. Diverse possibilities could be suggested on that: first, the stress was not enough to expedite apoptosis; second, apoptosis-related protein was already being secreted though not detected with microscope; third, clusterin, a major secretion molecule of saliva, decreased with saliva's malfunction due to stress. In the respect, it will be necessary to examine proteins expressed in case of cell death or other heat-shock proteins at the same time, in order to see whether any cellular change or death is caused by decreasing clusterin under high stress, and whether the original state is restored as time goes by under mild stress, through longer-term tests using even higher acute stress.
