BACKGROUND: The polymerase chain reaction(PCR) assay is rapid, sensitive analytical technique but has problem of high false-positive rate. We applied dUTP-UDG PCR (dU-PCR) method to prevent carryover contamination major source of high false positive in PCR assays, for detection of Mycobacterium tuberculosis. METHODS: The PCRs for detection of M. tuberculosis were performed with P1 and P2 primers based on IS6110 repeated sequence. FTC-2000 was used for capillary PCR and Uno-Thermoblock was used for heating block PCR. In order to evaluate the effect of dU-PCR controlling carryover contamination, PCRs were performed in the presence of UDG and the absence of UDG. To compare the sensitivity of usual dT-PCR with dU-PCR, chromosomal DNA of M. tuberculosis ranging 500pg to 0.5fg were amplified by dT-PCR and dU-PCR method using two different thermocycler, capillary and heating block type, respectively. RESULT: The dU-PCR using UDG prevented carryover contamination by amplicon DNA up to 500pg. By capillay PCR method, the lower limits of detectability of dT-PCR and dU-PCR were 0.5fg and 500fg, respectively, which indicates the sensitivity of dU-PCR was lower than dT-PCR. But by heating block method, the lower limits of detectability of both method of dU and dT-PCR were 0.5fg. So the sensitivity of dU-PCR was same as dT-PCR. CONCLUSION: The dU-PCR by heating-block method was sensitive test for detection of M. tuberculosis that effectively prevent carryover contamination by amplicon.

Adenocarcinoma in adenomyosis is unusual and it is mostly associated with adenocarcinoma in the endometrial mucosa. In contrast, adenocarcinoma arising in adenomyosis without endometrial adenocarcinoma is extremely rare and it suggests that it arises de novo from adenomyosis. We report a case of adenocarcinoma arising in adenomyosis in 44-year-old woman. The endometrial cavity contained a polypoid lesion with atypical hyperplasia, but no evidence of adenocarcinoma in the endometrial mucosa. Simple, complex and atypical hyperplasia associated with well differentiated adenocarcinoma was also noted in the areas of adenomyosis.

6.The Effects of an Integrated Management Program on Physical Function, Cognitive Function, and Depression in Patients with Subacute stroke
Journal of Korean Critical Care Nursing 2021;14(1):50-62
Purpose:
: This study examined the effects of an integrated management program on physical function, cognitive function, and depression in patients with subacute stroke.
Methods:
: A nonequivalent control group design was adopted. The participants were assigned to either the experimental group (n=20) or control group (n=23). The experimental group received an 8-week integrated management program and standard rehabilitation service (i.e., physical therapy and occupational therapy), while the control group received the standard rehabilitation service only. Physical function was measured as gait speed and balance ability using the Berg Balance Scale (BBS). Cognitive function was measured with neuro-behavioral cognitive status examination (NCSE), and depression was measured using the Beck Depression Inventory-II (BDI-II). Repeated measure ANOVA was used to determine changes in physical function, cognitive function, and depression over 8-weeks.
Results:
: The interaction between group and time was significant, indicating that the experimental group showed improvement in gait speed, balance ability, cognitive function (linguistic ability, linguistic memory, reasoning), and a decrease in depression compared to the control group.
Conclusion
: These results indicate that the integrated management program developed herein was beneficial in restoring physical function, cognitive function, and depression in subacute stroke patients.

PURPOSE: The purpose of this study was to identify the effect of family stressors, family strains, general family values, family values for hospitalized children and family hardiness on family adaptation based upon McCubbin's family resilience model for families of hospitalized children in China. METHODS: A survey using a self-report questionnaire was conducted with 330 hospitalized children's parents. Six instruments were used in this model. The data were analyzed using SPSS WIN 19.0 and AMOS 19.0 program. RESULTS: Family strain had a significant negative direct effect, general family values and family hardiness had a significant positive direct effect, and family values for hospitalized children had a significant positive direct effect and indirect effect on family adaptation of hospitalized children. CONCLUSION: In this study McCubbin's resilience model and resiliency factors were identified. According to the finding of this study nursing interventions to reduce family stress, enhance family hardiness and consolidate general family values and family values for hospitalized children can help to increase family adaptation in families of hospitalized children. Therefore, the significance of this study is that the results can be used to develop family nursing intervention programs based on family resilience to strengthen family adaptation in families of hospitalized children.

The main objectives of this study were to analyze the concept of hope, so to provide basic data to develop a valid instrument to measure hope, and to develop hope enhancing nursing intervention a program for cancer patients. The hybrid model approach was applied in three phases, the theoretical phase, the empirical phase, and the analytic phase. The study was developed on universal attributes explaining generalized hope and specific hope, which were revealed in a comprehensive review of the literature. In the empirical phase, eight cancer patients undergoing chemotherapy were interviewed to reveal causes, motivation, and their resource of hope according to The Hope Assessment Guide (Farren, Herth, & Popovich, 1995). In the analytical phase, the results of the two previous stages of the study were compared. The results were as follows: In the theoretical phase, six dimensions of hope emerged; affective, cognitive, behavioral, affiliative, temporal and contextual dimension. The antecedent of hope was loss, crisis, uncertainity, and stress. The consequences were renewal, development of new methods, safety, peace and transcendental competence. In the empirical phase, these six dimensions emerged as theoretical phases were verified and specified as these descriptive terms: feeling, intention, expectation, activity, relation, future- orientation, reality and goal-setting. The antecedent factor of hope was occurrence or recurrence of cancer. The consequence of hope was ability to cope with real condition, feeling of safety and comfort, peace, development of new strategy and recovery of disease. The major content of hope in this phase was related to specific hope, but it was also influenced on by general hope. In the analytic phase, general and specific hope was renamed as trait and state hope. All attributes emerged at the empirical phases, and also emerged at the theoretical phase. However, cognitive and contextual dimensions were revised and specified. In conclusion, the concept of hope is divided into trait hope and state hope, and state hope is an anticipatory expectation that occurs at the time of a stressful stimulus, such as being diagnosed with cancer. Hope is a multidimensional dynamic energized mental state which has the dimensions of affective, cognitive, behavioral, affiliative, temporal and contextual. There should be further studies to develope the state and trait hope scale according to definition and attributes of hope investigated in this study. In addition, considering results of the empirical phase, the family is very a important factor as a resource of hope, so it is necessary to consider family in implementing a nursing intervention program to enhance hope.

Purpose: The purpose of this study is to use finite element analysis to predict the fatigue life of an implant system subjected to fatigue load by mastication (chewing force). The reliability and the stability of implant system can be defined in terms of the fatigue strength. Not only an implant is expensive but also it is almost impossible to correct after it is inserted. From a bio-engineering standpoint, the fatigue strength of the dental implant system must be evaluated by simulation (FEA). Material and Methods: Finite element analysis and fatigue test are performed to estimate the fatigue strength of the implant system. Mesh of implant is generated with the actual shape and size. In this paper, the fatigue strength of implant system is estimated: U-fit (T.Strong, Korea, internal type). The stress field in implant is calculated by elastic-plastic finite element analysis. The equivalent fatigue stress, considering the contact and preload stretching of a screw by torque for tightening an abutment, is obtained by means of Sine's method. To evaluate the reliability of the calculated fatigue strength, fatigue test is performed. Results: A comparison of the calculated fatigue strength with experimental data showed the validity and accuracy of the proposed method. The initiation points of the fatigue failure in the implant system exist in the region of high equivalent fatigue stress values. Conclusion: The above proposed method for fatigue life estimation can be applied to other configurations of the differently designed and improved implant. In order to prove reliability of prototype implant, fatigue test should be executed. The proposed method is economical for the prediction of fatigue life because fatigue testing, which is time consuming and precision-dependent, is not required.
