The paste-type adhesive can be stored for a certain period of time and can be cured at room temperature. So it is mainly used for crack patching repair of aircraft airframe structures. This study analysed the influence of environmental factors and evaluated the adherence strength characteristics according to the adherence delay time of the paste-type adhesive. The test specimens were made of aluminum alloy(AL 2024-T3) with reference to ASTM D1002 which is generally performed to measure the adherence strength of the adhesive used for metal bonding. As a result of analysing the influence of temperature and humidity, it was found that the optimal temperature range is $24.5{\pm}0.5^{\circ}C$ and the optimal humidity range is $71{\pm}1%$ for maintenance work of the aircraft using EA-9320 adhesive. In addition, the adherence strength did not decrease with the inherent application time of the EA-9320, but it was found that the adherence strength dropped rapidly when the applied time exceeded the inherent application time of it.

Purpose: Adherence to treatment with inhaled corticosteroids (ICS) is a critical determinant of asthma control. The objective of this study was to assess factors that determine adherence to ICS therapy in children with asthma. Methods: Fifty-eight children with asthma, aged 5 to 16 years, used ICS with or without a spacer for 3 months. Adherence rates as measured from questionnaires and canisters, asthma symptom scores, and inhalation technique scores were assessed every 30 days. The degree of supervision by caregivers was assessed at day 30. Results: Adherence rates measured using canisters were lower at day 60 than at day 30 (P=0.044) and did not change thereafter ($74.4%{\pm}17.4%$ at day 30, $66.5%{\pm}18.4%$ at day 60, and $67.4%{\pm}22.2%$ at day 90). Adherence rates at days 60 and 90 and during the total study period were significantly different when measured by using questionnaires versus canisters (P<0.001, P=0.022, and P =0.001, respectively). In the comparison of adherence rates repeatedly measured at days 30, 60, and 90 and adherence rates during the total study period among the 3 groups, adherence rates in the high-degree supervision group were significantly higher than those in the low-degree supervision group ($82.0{\pm}16.0$ vs. $66.1{\pm}14.5$, $75.4{\pm}14.4$ vs. $56.2{\pm}18.4$, $75.0{\pm}18.3$ vs. $55.0{\pm}19.7$ [P=0.027]; $77.9{\pm}12.2$ vs. $59.1{\pm}11.4$ [P=0.021]) after adjustment for sex and age. Conclusion: The level of caregiver supervision is an important factor affecting adherence to ICS therapy in children with asthma. Therefore, a high degree of supervision may be required to increase adherence to ICS therapy in children with asthma.

Background : To improve medication adherence in elderly patients, the role of pharmacists in teambased services has been highlighted in the literature. However, not much is known about the role and the service elements involved in comprehensive geriatric programs in South Korea. This study was designed to describe the current status of medication adherence in geriatric patients based on the comprehensive geriatric assessment program and analyze the predictive factors for medication adherence in a tertiary teaching hospital. Methods : A retrospective cohort study was performed using electronic medical records of 247 patients from March 1st, 2015 to August 31st, 2015. Medication adherence and the types of non-adherence were also collected. Predictive factors for adherence were evaluated by including factors related to demographics, medications, illness, and patterns of medical usage. Results : The mean age of the study population was 81.2 years (range 65~98 years) and they were taking 9.7 drugs on an average (SD 5.0 drugs). The overall rate of non-adherence was 34%. About 48% of the patients had any forms of assistance in the medication administration. The most common type of non-adherence was "self-adjustment". The multivariate analyses revealed that age (adjusted odds ratio, 0.87 [95% CI, 0.80-0.96]; p 0.05) and the number of inappropriate medications (adjusted odds ratio, 0.59 [95% CI, 0.40-0.89]; p 0.05) were strong predictors for non-adherence. Conclusions : These results indicate that strategic considerations of the predictors of non-adherence should be improved in medication counseling services targeting elderly patients.

Tuberculosis (TB) is a significant public health concern. Globally, TB is among the top 10 and the leading cause of death due to a single infectious agent. Providing standard anti-TB therapy for at least 6 months is recommended as one of the crucial strategies to control the TB epidemic. However, the long duration of TB treatment raised the issue of non-adherence. Non-adherence to TB therapy could negatively affect clinical and public health outcomes. Thus, directly observed therapy (DOT) has been introduced as a standard strategy to improve anti-TB medication adherence. Nonetheless, the DOT approach has been criticized due to inconvenience, stigma, reduced economic productivity, and reduced quality of life, which ultimately could complicate adherence issues. Apart from that, its effectiveness in improving anti-TB adherence is debatable. Therefore, digital technology could be an essential tool to enhance the implementation of DOT. Incorporating the health belief model (HBM) into digital technology can further increase its effectiveness in changing behavior and improving medication adherence. This article aimed to review the latest evidence regarding TB medication non-adherence, its associated factors, DOT's efficacy and its alternatives, and the use of digital technology and HBM in improving medication adherence. This paper used the narrative review methodology to analyze related articles to address the study objectives. Conventional DOT has several disadvantages in TB management. Integrating HBM in digital technology development is potentially effective in improving medication adherence. Digital technology provides an opportunity to improve medication adherence to overcome various issues related to DOT implementation.

BACKGROUND/OBJECTIVES: The Seoul Metabolic Syndrome Management (SMESY) program is a 1-yr lifestyle modification program targeting metabolic syndrome (MetS) in Seoul residents. This study investigated the associations between adherence to dietary guidelines and MetS among the SMESY program participants. SUBJECTS/METHODS: Data of 54,385 participants aged 20-64 yrs who completed the SMESY program in 2015, had information on adherence to dietary guidelines, and were not medicated for diabetes, hypertension, or dyslipidemia were analyzed. Participants underwent MetS screening and completed a lifestyle questionnaire including adherence to 10 dietary guidelines before and after participation. Participants were classified according to the number of MetS risk factors at baseline (MetS group, ≥ 3; risk group, 1-2; healthy group, none). Adherence to dietary guidelines was determined from the number of "yes" responses regarding the fulfillment of each guideline on ≥ 5 days/week. Multiple logistic regression was used to evaluate associations between newly diagnosed MetS and changes in adherence to dietary guidelines. RESULTS: In the MetS group, MetS prevalence decreased after the SMESY program (men, -41.9%p; women, -48.7%p), and all risk factors were significantly improved (P < 0.0001). All groups exhibited improved adherence to all dietary guidelines after participation (P < 0.0001). In the MetS group with positively changed adherence scores, the MetS prevalence decreased by -44.1%p for men and -49.5%p for women, whereas the prevalence in those with negative changes decreased by -38.1%p for men and -48.6%p for women. In the risk group, those with positively changed adherence scores had significantly decreased odds ratios (ORs) for newly diagnosed MetS compared with those with negative changes (OR, 0.70; 95% confidence interval [CI], 0.61-0.80 for men; OR, 0.88; 95% CI, 0.79-0.99 for women). CONCLUSIONS: The SMESY program may effectively reduce the risk of MetS among adults with risk factors by improving adherence to dietary guidelines.

Purpose: The purposes of this study were to examine the relationships between health literacy, self-efficacy, social support, and medication adherence and to determine its impact on medication adherence in the elderly. Methods: This study was a descriptive research study. Structured questionnaires were used for survey with a convenience sample of 220 elderly in a community. Data were analyzed using descriptive statistics, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression with IBM SPSS 18.0. Results: The mean scores of health literacy, self-efficacy, social support, and medication adherence were $35.89{\pm}19.39$, $55.34{\pm}7.44$, $86.54{\pm}15.90$ and $4.82{\pm}1.83$, respectively. There were significant correlations between health literacy, self-efficacy, social support, and medication adherence. Social support (${\beta}=.23$, p=.001) and health literacy (${\beta}=.21$, p=.002) were significantly associated factors with medication adherence. Conclusion: This finding showed that nursing interventions to promote medication adherence in the elderly group should focus on social support program and health literacy intervention.

Purpose: Adherence to immunosuppressants is the key to prevent organ rejection in organ transplant recipients. The purpose of this study was to investigate current interventions to improve adherence to immunosuppressants in liver transplant recipients. Methods: A systemic literature search was done using PubMed, Embase, Cochrane Library, CINAHL and four Korean databases to identify experimental studies reported in English or Korean up to and including 2015. We identified eight intervention studies on the adherence to immunosuppressants in liver transplant recipients independently reviewed by two reviewers. The quality and risk of bias of the selected studies were assessed. Results: Education, conversion of regimen, and text messaging were identified as intervention techniques to improve adherence. We found positive results in three out of four studies implementing educational strategies, but the results were not sufficient to draw a definite conclusion. Conversion from a twice-daily tacrolimus-based regimen to a once-daily tacrolimus extended-release formula was used in three adult-only studies and its effectiveness was confirmed. One study showed that improved adherence and outcomes were effected by using text messaging with pediatric patients. Conclusion: Future research is needed to facilitate interventions to improve adherence to immunosuppressants in various ages of patients including pediatric/adolescent liver transplant recipients.

Social and behavioral scientists have proposed that a person's belief system crucially influences his or her behaviour, and therefore may affect outcomes of pain management. The purpose of this study was to explore the relationship between analgesic beliefs, analgesic adherence and pain experience amongst Taiwanese cancer outpatients. The cross-sectional study included 92 oncology outpatients in two teaching hospitals in the Taipei area of Taiwan. The research instruments included the Pain Opioid Analgesic Beliefs Scale-Cancer (POABS-CA), opioid adherence, and the Brief Pain Inventory-Chinese (BPI-Chinese). Beliefs about pain and opioids demonstrated a significant relationship with patients' opioid adherence (r = -0.30, p < 0.01). The more negative beliefs regarding opioids and pain the patient had, the worse their adherence to around the clock (ATC) analgesic regimen. However, there was no significant correlation between opioid belief and pain experience. As well, there were no significant relationships between adherence to opioid regimen and any of the measures of pain experience. The study highlights the potential importance of a patient's pain and opioid beliefs in adherence to pain medication.
