Objectives : The objective of this study was to investigate the relationship between psychological distress and pain in cancer patients. Methods : 249 patients with cancer who visited National Health Insurance Service Ilsan Hospital between April 2013 and March 2014 were evaluated with National Cancer Center Psychological Symptom Inventory(NCC-PSI) which consisted of Modified Distress Thermometer(MDT) and Modified Impact Thermometer(MIT). Each scale was divided into 3 subscales targeting separate symptoms: insomnia, anxiety, and depression. Psychological distress was defined as positive for those who scored above the cutoff values in at least one of all six subscales. The Numeric Rating Scale for Pain(NRS-Pain) was used to assess the subjective severity of pain. Logistic regression was performed to investigate the association between psychological distress and pain. Results : Univariate logistic regression analysis showed that pain, gender, compliance, and two subscale scores of Hospital Anxiety and Depression Scale(HADS) were significantly associated with psychological distress. Multivariate logistic regression analysis showed that pain and HADS anxiety subscale score maintained a statistically significant association with psychological distress adjusted for variables including age, gender, years of education, Eastern Cooperative Oncology Group performance status, cancer stage, Charlson Comorbidity Index, compliance, and HADS depression subscale score. One point increase in pain was 1.31 times more likely to cause psychological distress. In secondary analysis, pain was significantly associated with all subscales of NCC-PSI, except MIT-anxiety subscale. Conclusions : This study suggests that NCC-PSI, a screening tool for psychological distress, reflects pain. We recommend that physicians who treat cancer patients consider the examination of psychological distress which provides comprehensive evaluation of various factors regarding quality of life.

Objectives In this study, we identified the symptoms of insomnia, anxiety, and depressed mood in newly diagnosed women breast and thyroid cancer patients. Methods The subjects of this study were 1794 women patients who visited the Ewha Womans University Cancer Center for Women. They included 1119 newly diagnosed primary breast cancer patients and 675 newly diagnosed primary thyroid cancer patients. The patients completed the National Cancer Center Psychological Symptom Inventory (NCC-PSI) during their first follow-up visit after surgery, before starting chemotherapy or radiotherapy. The NCC-PSI is composed of the modified distress thermometer (MDT) and the modified impact thermometer (MIT) for insomnia, anxiety, and depressed mood. Results Anxiety severity was found to be greater in breast cancer patients than in thyroid cancer patients. Significant levels of anxiety, depressed mood and insomnia were present in 28, 24.5, and 20.7% in all the subjects, respectively. Moreover, anxiety symptoms, depressed mood and insomnia interfered with the daily lives of 20, 18.4, and 14.2% of all the subjects, respectively. Dealing with anxiety (18.8%) was found to need the most help, followed by dealing with insomnia (8.9%) and depressed mood (8.7%). Conclusions A significant level of distress was found in about 40% of the total subjects. Nearly 30% of newly diagnosed breast cancer patients reported significant anxiety symptoms and interferences with daily living caused by anxiety, which most commonly needed special care. Early assessment and management of psychological distress, especially anxiety, in breast and thyroid cancer treatment are very important to establish integrated cancer care.

Purpose: The purpose of this study was to describe the impact of fatigue and distress on self-efficacy among breast cancer survivors and to provide a base for development of nursing intervention strategy to improve self-efficacy. Methods: A descriptive research design was used. The subjects were 158 patients who were either being treated or were receiving follow-up care at a university breast center in D City from May 30 to August 30, 2014. Structured questionnaires, Revised Piper Fatigue Scale, Distress Thermometer, and Self-Efficacy Scale for Self-Management of Breast Cancer were used to measure fatigue, distress, and self-efficacy. Data were analyzed using t-test, ANOVA, Pearson's correlation coefficients, and multiple regressions. Results: The mean scores of fatigue, distress, and self-efficacy were 3.83, 4.31, and 3.77, respectively. There were significant differences among participants in terms of educational background, current treatment methods, perceived health status, economic burden for fatigue and perceived health status for distress. Self-efficacy was impacted by age, educational background, marital status, average monthly income, perceived health status, and medical expenses. Fatigue, age, and the burden on medical expense had the most impact on self-efficacy, accounting for 17% of the variance. Conclusion: Fatigue should be managed to improve self-efficacy of breast cancer survivors. Therefore, nursing programs designed to decrease fatigue may be helpful.

In recent years, as people's attention on health, the demand for healthy crops such as mushrooms gradually increased. Farmers use plastic greenhouse cultivation mode more and more in order to reduce the impact of outdoor environment on crop cultivation, which requires farmers to adjust the greenhouse temperature at any time. But the majority of farmers still use a thermometer to measure temperature. This paper constructs an environment that can automatically adjust the temperature, so as to measuring temperature in real time, improving the efficiency of the farm work, and reducing unnecessary labor.

In this study, the impact of sand and weathered granite soil is analyzed by changing the internal temperature from $20^{\circ}C{\sim}70^{\circ}C$C by installing a heating coil inside the triaxial cell. To check the effect on weathered granite soil due to increase of temperature and number of heating-coiling cycles are analyzed by measuring the temperature by using thermometer installed inside the triaxial cell and due to that deviator stress also occurred during the consolidated undrained test. To analyze the effect of weathered granite soil with change of temperature during undrained testing. The deviator stress and pore pressure is measured. As a result, pore pressure increases and the deviator stress decreases with rise of temperature.

Objectives : The purpose of this study was to investigate of the color change, tooth surface and intra-pulpal temperature of tooth bleaching by light activation Methods : Forty-eight extracted bovine teeth were immersed into a tea solution for 24 hours. The specimens were randomly divided into four groups(n=15):(G1) 15% HP + without light activation, (G2) 15% HP + light activation, (G3) 25% HP + without light activation, (G4) 25% HP + light activation. All specimens were bleached for 15 minutes three times. The spectrophotometer (CM-2600d, Konica Minolta, Osaka, Japan) was used including before bleaching, immediately after bleaching, 1 week, 1 and 3 months after the end of bleaching. The temperature rise were measured in the pulpal chamber and tooth surface with a digital thermocouple thermometer(Termopar Digital Multimeter, Tektronix DMM916, USA). Between the tested time points, the specimens were stored in distilled water. The data were analyzed by ANOVA, t-test and Tukey's post hoc test set at 0.05. Results : There was no significant color change by the use of light after the bleaching treatment(p>0.05). The dental bleaching treatments of teeth with 15% HP and 25% HP did not seem to be more effective when light source was used. There was no difference in color stability between groups within three month(p>0.05). There was an increase in tooth surface and pulp temperature, but it was not sufficient to cause damage to the pulp. Conclusions :The use of light activation has no obvious effective impact on the tooth bleaching effect.

The purpose of the cultivated crops have been changes in the aim of improving quality production. In recent years, as people's attention on health, the demand for healthy crops such as mushrooms gradually increased. In the process of mushroom factory production, regulation of environmental factors directly affects the yield and quality of mushroom. In related to the methods of mushroom cultivation, the recent technologies apply the new technology such as sensors and IT convergence services. And then cultivating mushroom is managed effectively. Farmers use plastic greenhouse cultivation mode more and more in order to reduce the impact of outdoor environment on crop cultivation, which requires farmers to adjust the greenhouse temperature at any time. But the majority of farmers still use a thermometer to measure temperature. This paper constructs an environment that can automatically adjust the temperature, so as to measuring temperature in real time, improving the efficiency of the farm work, and reducing unnecessary labor.
