Objective Problematic online gaming (POG) and problematic Internet use (PIU) have become a serious public mental health problem, with Internet gaming disorder (IGD) included in “Conditions for further study” section of DSM-5. Although higher immersive tendency is observed in people affected by POG, little is known about the simultaneous effect of immersive tendency and its highly comorbid mental disorder, attention deficit/hyperactivity disorder (ADHD). This study aimed to assess the relationship between immersive tendency, ADHD, and IGD. Methods Cross-sectional interview study was conducted in Seoul, Korea with 51 male undergraduate students; 23 active gamers and 28 controls. Results Current ADHD symptoms showed partial mediation effect on the path of immersive tendency on POG and PIU. The mediation model with inattention explained variance in both POG and PIU better than other current ADHD symptom models (R2=69.2 in POG; 69.3 in PIU). Childhood ADHD symptoms models demonstrated mediation effect on both POG and PIU which explained less variance than current ADHD symptom models (R2=53.7 in POG; 52.1 in PIU). Current ADHD symptoms, especially inattention, appear to mediate the effect of immersive tendency on POG/PIU. Conclusion Immersive tendencies may entail greater susceptibility to IGD, and comorbidity with ADHD may mediate the effect of immersive tendency on IGD.

<P>Objective Risk factors for chemotherapy-induced nausea and vomiting (CINV) include older age, female sex, alcohol consumption, and a history of motion sickness. Although gastrointestinal symptoms are found to be related with sleep and mood in other conditions, little is known about their effects on CINV. Methods This prospective observational study recruited patients with early-stage breast cancer who had recovered from surgery before receiving a first cycle of anthracycline and cyclophosphamide-based chemotherapy. Candidate factors associated with CINV were assessed before chemotherapy by using the following: the Pittsburgh Sleep Quality Index, the Insomnia Severity Index, the Epworth Sleepiness Scale, and the Hospital Anxiety and Depression Scale. Chemotherapy-induced nausea (CIN) and chemotherapy-induced vomiting (CIV) were defined according to a numeric rating scale (0-10) as follows: 3, nausea; 1, vomiting. Results Between February 2012 and May 2014, data were collected from 198 patients. Chemotherapy-induced nausea occurred in 35.4% of patients, and CIV occurred in 31.3%. Chemotherapy-induced nausea was significantly associated with poor sleep quality (odds ratio [OR], 2.48; 95% confidence interval [CI], 1.13-5.46; p = 0.024) and pretreatment nausea (OR, 4.81; 95% CI, 1.84-12.62; p = 0.001). Likewise, CIV was significantly associated with poor sleep quality (OR, 2.64; 95% CI, 1.21-5.78; p = 0.015) and pretreatment nausea (OR, 3.07; 95% CI, 1.23-7.66; p = 0.016). Conclusions Poor sleep quality increases risk of CINV in patients with breast cancer. Sleep problems should be assessed and considered in the management of CINV.</P>

Objective Pre-treatment anxiety (PA) before chemotherapy increases complaints of chemotherapy-related symptoms (CRS). The results on the association have been inconsistent, and the effect of temperament remains unclear. We aimed to determine whether PA is a risk factor for CRS and the effect of differing temperaments on CRS.Methods This prospective study comprised 176 breast cancer patients awaiting adjuvant chemotherapy post-surgery. We assessed CRS, PA, and temperament using the MD Anderson Symptom Inventory (MDASI), the Hospital Anxiety and Depression Scale, and the short form of the Temperament and Character Inventory-Revised, respectively. The MDASI was re-administered three weeks after the first chemo-cycle.Results PA showed weak positive correlation with several CRS after the first cycle; no CRS was significantly associated with PA when pre-treatment depressive symptoms and baseline CRS were adjusted in multiple regression analysis. Moderation model analysis indicated that the PA effect on several CRS, including pain, insomnia, anorexia, dry mouth, and vomiting, was moderated by harm avoidance (HA) but not by other temperament dimensions. In particular, PA was positively associated with CRS in patients with low HA.Conclusion The results in patients with low HA indicate that more attention to PA in patients with confident and optimistic temperaments is necessary.

The yield of 3D stacked IC manufacturing improves with the pre-bond integrity testing of through silicon vias (TSVs). In this paper, an efficient pre-bond test method is presented based on IEEE std. 1500, which can precisely diagnose any happening of TSV defects. The IEEE std. 1500 wrapper cells are augmented for the proposed method. The pre-bond TSV test can be performed by adjusting the driving strength of TSV drivers and the test clock frequency. The experimental results show the advantages of the proposed approach.

Various test data compression techniques have been developed to reduce the test costs of system–on–a–chips. In this paper, a scan chain reordering algorithm for code–based test data compression techniques is proposed. Scan cells within an acceptable relocation distance are ranked to reduce the number of conflicts in all test patterns and rearranged by a positioning algorithm to minimize the routing overhead. The proposed method is demonstrated on ISCAS ’89 benchmark circuits with their physical layout by using a 180 nm CMOS process library. Significant improvements are observed in compression ratio and test power consumption with minor routing overhead.
Cost-efficient Chip Identification Method using Scan Flip-flop based Physically Unclonable Function
Dooyoung Kim,M. Adil Ansari,Jihun Jung,Jinuk Kim,Sungju Park 대한전자공학회 2018 Journal of semiconductor technology and science Vol.18 No.2
Scan flip-flop based physically unclonable function (SCAN-PUF) has been proposed to protect integrated circuits (ICs) from security threats such as unauthorized access and IC cloning. In this paper, we propose an efficient SCAN-PUF technique that improves the uniqueness of responses with low cost overhead. The proposed SCAN-PUF first determines an optimal number of power-up state observations and then selects scan flip-flops as the PUF elements (P-ELEMENTs) through a given number of observations. A Bayesian model is adopted to evaluate the reliability of the P-ELEMENTs, and a grouped PELEMENT selection method is introduced to obtain more P-ELEMENTs than a predetermined threshold. To evaluate the proposed SCAN-PUF, we observed the power-up states of scan flip-flops from 15 chips fabricated using the 65-nm CMOS technology. The optimal number of observations is determined according to the reliability of the P-ELEMENTs, and the reliability, randomness, and uniqueness of the responses are then analyzed.

<P>Semiconductor aging is a serious threat to the reliability of a system. We address the aging level of semiconductor components by describing the degree of semiconductor aging under certain operating conditions, including voltage, frequency, temperature, and usage rate. Aging level information can be used to follow the real aging rate of a device, predict the remaining life, and control the device performance under certain degradation conditions by balancing the operation of various device components. Such applications can improve the reliability of automotive semiconductor systems, which should have longer lives than mobile systems. In this brief, we present an aging level estimating flip-flop (FF) that can be used for these and other applications as well. Moreover, we can control the operation of the proposed FF by controlling its clock and control signals. We demonstrate an application of the proposed FF for aging-monitoring, showing that, by halting the operation of the proposed FF, the power consumption is significantly reduced compared with other approaches.</P>

Evidence of the importance of early childhood development(ECD) has transformed child health monitoring and screeningtools. Development of the Korean Developmental ScreeningTest for Infants and Children (K-DST) has expanded theapplications of child health screening to a large number ofinfants and children in Korea and is contributing to the earlydetection of neurodevelopmental disorders and delivery oftimely interventions. The previous screening tool (KoreanAges and Stages Questionnaire) raised some concerns, as itslack of consideration of the cultural background of the Koreanpopulation can lead to inaccurate or imprecise diagnoses. TheK-DST, a tailored tool for Korean infants and children, is asimple and cost-efficient solution for child health monitoringand screening. This review focuses on the development androle of the K-DST in ensuring ECD. Here we review use of theK-DST for ECD screenings and discuss the best strategy for itsuse in other countries
