Purpose: In numerous studies, MBSR programs have been shown to reduce stress and improve health-related QOL. Although MBSR programs have been shown to be beneficial, its effects have not been well-determined among Korean populations in clinical nursing practice. The purpose of this review was to describe the effects of MBSR on stress and health-related QOL so that the potential benefits of this intervention may be evaluated for wider application in Korea. Methods: Articles published in peer-reviewed journals in the English or Korean language up to 2009 were reviewed; 14 articles met the inclusion criteria for this review and there were no Korean papers. Results: MBSR groups were found to have significantly reduced stress outcomes relative to non-MBSR groups in 6 of 11 studies. In regards to health-related QOL, participants of the MBSR programs had increased scores after MBSR intervention relative to control groups in 5 of 7 studies. Conclusion: MBSR programs was effective in decreasing stress and increased the health-related QOL in the majority of studies reviewed. MBSR merits study in Korean patients to determine whether similar salutary patient outcomes may be obtained.

This study aimed to analyze the six personality factors of rehabilitation therapists and to identify the effects of these factors on their job stress and turnover intention. This study involved physical therapists and occupational therapists as rehabilitation therapists. A structured questionnaire was distributed to rehabilitation therapists, and 186 answered copies were used for data analysis. The results of the survey were as follows: Among the six personality factors, the rehabilitation therapists showed the highest level of honesty-humility and the lowest level of openness to experience. In terms of job stress, the subjects experienced the highest level of stress from job autonomy and the lowest level of stress from relationship conflict. In terms of turnover intention and work motivation reduction, the subjects scored above the median points, showing their high levels of turnover intention. In addition, higher levels of extraversion and agreeableness in the rehabilitation therapists led to a statistically significant reduction in their turnover intention and a statistically significant decrease in most of their job stress factors. Based on these results, organizational management aimed at increasing the personality factors of extraversion and agreeableness is necessary as a measure to effectively manage rehabilitation therapists' job stress and turnover intention.

Purpose: The purpose of this study was to evaluate retrospectively the clinical results of closed reduction and percutaneous screw fixation for unstable injuries on stress radiographs in subtle injuries of Lisfranc joint. Materials and Methods: From June 1997 to March 2003, 6 cases of unstable injuries on stress radiograph in subtle injuries of Lisfranc joint were treated by percutaneous cannulated screw fixation after closed reduction. All cases were injuried by indirect force (twisting injury). The average diastasis between the 1st and 2nd metatarsal base was 3 mm (2-4 mm) on initial nonweight bearing AP radiograph. The average follow-up period was 20 months. Clinical evaluation was assessed according to the American Orthopedic Foot and Ankle Society (AOFAS) midfoot score. Results: The AOFAS midfoot score was average 86 (80-90) points. The average diastasis between 1st and 2nd metatarsal base was 2 mm (1-3 mm) on weight bearing AP radiograph in final follow up. The final diastasis was increased slightly than diastasis in initial postoperative radiographs. But the clinical results were good. There was no correlation between the degree of diastasis and the clinical results. On weight bearing lateral radiograph, the average difference with normal foot in the distance between plantar aspect of 5th metatarsus and medial cuneiform was 2 mm (0-3 mm). One case had mild arthritic change on the radiographs. Conclusion: When the Lisfranc injuries, especially in the subtle injuries were suspicious, the stress views are helpful to assess stability of the Lisfranc injuries and planning of treatment. For unstable injuries on stress radiographs in subtle injuries of Lisfranc joint, closed reduction and percutaneous screw fixation is useful method to expect good clinical results.

The objective of this paper is to verify clinical effects of Lyu's Soyosan(柳氏逍遙散) and Lyu's Kwipithang(柳氏歸脾湯). They were prescribed to the enperimental student group suffering from mental stress and annoyed by psychological instability. From the biochemical examination before and after medication, we measure the amount of hormonal variation in thyroid hormone(TSH, $T_4$) and adrenocortical hormone(ACTH, cortisol) The results are as follows. 1. The average of self-rating anxiety scale(SAS) in test group is $41.00\;{\pm}\;7.84$. This value is statistical significant and higher than one of normal person(age 20-39). The average of a global assesment of recent stress(GARS) scale is $28.62\;{\pm}9.00$. There is statistical correlation coefficient between SAS and GARS (p < 0.001). 2. Both Lyu's Soyosan(柳氏逍遙散) and Lyu.s Kwipithang (柳氏歸脾湯) groups show statistically significant reduction of total cholesterol and triglyceride level in serum lipid after ten day medication. 3. It is observed that Lyu's Soyisan(柳氏逍遙散) and Luy's Kwipithang (柳氏歸脾湯) groups have increasing tendency of TSH. The statistically significant reduction of $T_4$ was found in two groups after ten day medicaton. 4. It is observed that Lyu's Soyosan(柳氏逍遙散) and Lyu's kwipithang (柳氏歸脾湯) group have statistically significant reduction of serum cortisol level after ten day medication, Both groups have statistically significant reduction of plasma ACTH level after twenty day medication. From these results, it is verified that both Lyu's Soyosan(柳氏逍遙散) and Lyu's Kwipithang (柳氏歸脾湯) have anti-stress effects against psychological instability and mental stress. The Lyu's Soyosn(柳氏逍遙散) shows special effectiveness in depression of liver-energy(肝氣鬱結) and the Lyu's Kwipitang (柳氏歸脾湯) is also effective in deficiency heart-blood(心血不足).

This experiment was carried out on plastic pots ($40cm{\times}25cm{\times}30cm$) filled with sand soil at greenhouse using two soybean cultivars with small seed; one was Pungsannamulkong (PSNK) recognized as a tolerant cultivar against excessive water stress and the other one was Sobaeknamulkong (SBNK) recognized as a susceptible cultivar. Seed was sown with 30 plants of 2 hills, and the amount of applied fertilizer was N; 3.0 g, P; 3.0 g, and K; 3.4 g per $m^2$ with all basal fertilizations. Plants were grown under photoperiod of natural light with day temperature of $31{\pm}5^{\circ}C$ and night temperature of $22{\pm}1^{\circ}C$. The flooding treatment was done for 3, 5, 7 and 10 days by filling pots with tap water up to 1 cm above the level of the soil surface when plants were 2 days after emerging. Nitrogen uptake by leaves of soybeans decreased significantly by the flooding after 6 days. This significant reduction of N uptake by flooding was evidently recognized from the chlorosis of leaves. The dry matter of flooded soybean seedlings significantly decreased compared to non-flooded soybean seedlings at 10 days. The dry matter of roots also showed similar result of the shoot. Shoots had more N reduction than roots under the flooding. This N reduction was more pronounce in SBNK than in PSNK. Chlorophyll content of flooded soybeans showed decreasing or non-increasing tendency, and the reduction of chlorophyll content was more in SBNK than in PSNK from the flooding stress. Nitrate content of soybean seedlings with flooding stress showed decreasing tendency in shoot and root parts. Ammonium content, however, was higher in flooding stress compared to the non-flooding. Flooding caused a remarkable change in the AA (amino acid) composition and TAA (total amino acid) concentration in the leaves of soybean seedlings.

Objectives : The aim of this study was to investigate the correlation between the effectiveness of Brief Qigong-based Stress Reduction Program(BQSRP) and personality. Methods : Twenty nine women and nine men from the community with symptoms of distress(mean age 39.4 years, SD=11.4) were randomized into a group receiving a 4-week intervention of BQSRP(n=19) or a waiting-list control group. All subjects completed the temperament and character inventory (TCI) before the intervention. Before and after the intervention period, questionnaires were completed on perceived stress scale(PSS), anxiety, and quality of life. Results : 1. Those who have higher temperament of harm avoidance or lower character of self-directedness showed higher PSS, Hwa-Byung character, Hwa-Byung symptom, STAI and lower WHOQOL-BREF scores. 2. In the BQSRP training group, a correlation analysis demonstrated an association between higher temperament of harm avoidance and greater improvement of perceived stress and an association between lower character of self-directedness and greater improvement of perceived stress. 3. Those who have high Hwa-Byung symptom scores prefer the breathing meditation and there were no differences in effects of BQSRP group by the preference Brief Qigong-based Meditation(BQM) component. Conclusions : These results suggest that a BQSRP training may be effective for those with higher harm avoidance trait and low self-directedness.

The purpose of the study were to investigate the effect of the neuro-feedback program which improves brain function and stress reduction effect. The research design is one group pretest-posttest survey. 121 nursing students of a college in the Busan region took part in the study. Training involving the neuro-feedback program was conducted twice a week, 30 minutes per session, for a total of 10 weeks. The collected data was encoded and analyzed using SPSS 12.0 Version. The brain function and stress levels of the subjects were analyzed through the before-and-after results of the training were analyzed using a paired t-test. The results of the study showed that the BQ and SQ were enhanced as a result of the neuro-feedback. In particular, there were significant increases in the SRQ, ATQ, ACQ, and EQ of the BQ. SQ is correlated with the prevalence rate and resistance to disease, meaning not only psychological anxiety, uneasiness and excitement, but also physical anxiety and response to disease. Based on the study, by using the neuro-feedback training as a program for stress reduction, it is expected that nursing students will receive less stress from internal and external factors, and their ability to cope with stress will be enhanced.
