Objectives: We explored the characteristics of physiological variables such as electrodermal response(EDR) and electromyography(EMG) in patients with insomnia, panic disorder, and other anxiety disorders. we aimed to decide the minimum sessions in biofeedback treatment to make the treatment effective and examine the effects of long-term biofeedback treatment by measuring the physiological variables. Methods: Thirty seven outpatients who received biofeedback treatment were divided into 3 groups according to the number of biofeedback sessions(patients who received 4-5 sessions, who received 6-9 sessions, and who received more than 10 sessions). We measured mean and delta values of EDR and EMG levels, and the Hamilton Anxiety Rating Scale(HARS), and Slef-Relaxation Inventory(SRI) in all patients. Data were analyzed by t-test and repeated measures analysis of variance. Results: The mean and delta values of EDR and EMG levels were not different among the 3 groups during the first 4 biofeedback sessions. However, patients who received more than 10 biofeedback sessions had higher baseline mean EDR value(F=2.233, p=0.036) in the first session, compared with other patients. In patients who received more than 10 biofeedback sessions, mean EDR was significantly reduced after $5^{th}$ session(F=10.41, p<0.01). They showed significant improvement in SRI scores at 12th biofeedback session(t=2.726, p<0.05) and in HARS scores at $6^{th}$(t=3.10, p<0.05) and $12^{th}$ biofeedback session(t=10.93, p<0.001). Conclusions: Wesuggest that patients should receive more than 5 biofeedback sessions to experience internal cues and get a good clinical response to biofeedback treatment.

Purpose: This study was aimed to analyze how social workers understand the rights for elderly patient and family caregiver to make end-of-life (EOL) care decisions and their roles the decision making process. Methods: The study employed a quantitative research method of collecting data from a structured questionnaire that was filled out by 334 social workers at long-term care facilities. Data were analyzed by descriptive statistics, mean differences, correlation between variables, using SPSS 20.0 program. Results: The mean score for the understanding the rights to an EOL care decision was $3.46{\pm}0.69$ and of their own roles $3.48{\pm}0.84$. The level of understanding significantly differed by social workers' experience of assisting a process to make an EOL care decision such as advance directives and life sustaining treatment, work experience, and the number of beds. Positive correlation was observed between the level of understanding of the rights for EOL care decisions and of social workers' roles (Pearson r=0.329, P<0.001). Conclusion: This study proposes development of an education program for social workers and devising standards for the EOL care decision making process to protect elderly patients, family caregivers as well as social workers in a long term care facility.

The surgical management of complete transposition of the great arteries, ventricular septal defect, and pulmonary stenosis still remain a significant challenge. The Rastelli (REV procedure) remains the most widely applied procedure for surgical repair of these lesions. Although the Rastelli procedure can be performed with good early results, the intermediate- and long-term results have been less than satisfactory because of deterioration of the hemodynamic performance of the LVOT or RVOT. We performed a modified Nikaidoh procedure as an alternative surgical procedure in a 19-month-old boy weighing 10.4 kg with this anomaly. Aortic translocation with biventricular outflow tract reconstruction resulted in a more "normal" anatomic repair and postoperative echocardiography showed straight, direct, and unobstructed ventricular outflow.

This study aimed to identify influences which nutritional status and depression have on satisfaction with life on middle-aged long-term care patients. This study is a descriptive study conducted with 120 patients aged 40-65 from February 1st to March 31th, 2015 in hospital. Data were analyzed using t-test, ANOVA, Scheff's test, Pearson's correlation coefficients, multiple regression. The average of nutrition status, depression, satisfaction of life was $15.85{\pm}3.85$, $24.70{\pm}15.85$, $3.54{\pm}1.22$ each. The findings show nutritional status(r=.281, p<.005) have correlation(+) with satisfaction of life, otherwise, nutritional status(r=.439, p<.001) and satisfaction of life(r=-.-574, p<.001) have correlation(-) with depression both. Influencing factors on satisfaction of life were subjective health(${\beta}=.387$, p=.000) and depression(${\beta}=.251$, p=.010), explained 36.0% of the variance. Therefore, management program for improving satisfaction of life is needed on middle-aged long term care patients.

To deal with tumor motion from respiration is one of the important issues for the advanced treatment techniques, such as the intensity modulated radiation therapy (IMRT), the image guided radiation therapy (IGRT), the three dimensional conformal therapy (3D-CRT) and the Cyber Knife. Studies including the active breath control (ABC) and the gated radiation therapy have been reported. Authors have developed the device for reducing the respiration effects and the diaphragm motions with this device were observed to determined the effectiveness of the device. The device consists of four belts to immobilize diaphragm motion and the vacuum cushion. Diaphragm motions without and with device were monitored fluoroscopically. Diaphragm motion ranges were found to be 1.14 ～ 3.14 cm (average 2.14 cm) without the device and 0.72～1.95 cm (average 1.16 cm) with the device. The motion ranges were decreased 20 ～ 68.4% (average 44.9%.) However, the respiration cycle was increased from 4.4 seconds to 3.7 seconds. The CTV-PTV margin could be decreased significantly with the device developed in this study, which may be applied to the treatments of the tumor sited diaphragm region.

Background : Current studies on multimodal strategy for N2 non-small cell lung cancer are being high interest, have drawn much attention. N2 lung cancer, however, is composed of is divided into several sub groups with that have different prognoses. The prognostic factors still remain controversial. Methods : Between January 1990 and June 1999, 180 patients with N2 lung cancer who underwent surgical resection were investigated, excluding 10 of these for surgical mortality. All patients underwent mediastinal lymph node dissection. 20 clinicopathologic factors were investigated by univariable and multivariable analyses to identify significant prognostic factors among resected N2 disease. Results : The overall 5-year survival rate was 20.6%. Multivariable analyses among overall patients revealed 3 significant prognostic factors : Age, Histologic type, Vascular invasion. Based on the result, 49 patients with both age more than 60 and pathologic Non-squamous cell showed a 5-year survival of 5.0%, whereas 37 patients with neither of the factors showed a 5-year survival of 56.6%(p<0.001). And 12 patients with both vascular invasion and pathologic Non-squamous cell showed a 5-year survival of 11.9%, whereas 67 patients with neither of the factors showed a 5-year survival of 33.6%(p=0.01). Conclusion : The prognosis of surgically resected N2 disease varies according to the 3 significant prognosis factors. Tumor size may be an additional influencing factor in the prognosis of N2 disease.
