Background: Efficacy of childhood cancer treatment in low-income countries may be impacted by parents' and health-care providers' perspectives on chemotherapy-related side-effects. This study explores prevalence and severity of side-effects in childhood cancer, and compares health beliefs about side-effects between parents and health-care providers, and between nurses and doctors in Indonesia. Materials and Methods: Semi-structured questionnaires were filled in by 40 parents and 207 health-care providers in an academic hospital. Results: Parents exporessed a desire to receive more information about side-effects (98%) and worried about this aspect of treatment (90%), although side-effects were less severe than expected (66%). The most frequent was behavior alteration (98%) and the most severe was hair loss. Only 26% of parents consulted doctors about side-effects. More parents, compared to health-care providers, believed that medicines work better when side-effects are more severe (p<0.001), and accepted severe side-effects (p=0.021). More health-care providers, compared to parents, believed that chemotherapy can be stopped or the dosage altered when there are side-effects (p=0.011). More nurses, compared to doctors, stated that side-effects were unbearable (p=0.004) and made them doubt efficacy of treatment (p<0.001). Conclusions: Behavior alteration is the most frequent and hair loss the most severe side-effect. Apparent discrepancies in health beliefs about side-effects exist between parents and health-care providers. A sustainable parental education program about side-effects is recommended. Health-care providers need to update and improve their knowledge and communication skills in order to give appropriate information. Suchmeasures may improve outcome of childhood cancer treatment in low-income countries, where adherence to therapy is a major issue.

A side-channel attack is a method of attacking a cipher based on physical information of a cryptographic device. The masking method, which is a typical method overcoming this attack, is a method of calculating an arbitrary masking value at the round intermediate value through rounds. Thus, it is difficult to guess the intermediate value by the side-channel attack, but if the masking operation is applied to all rounds of the encryption algorithm, the encryption process may become overloaded. Therefore, it is practical to use a reduced-round masking technique that applies a masking technique to only a part of the cipher for lightweight equipment such as Internet of Things(IoT) and wearable devices. In this paper, we describe a Hamming weight filtering for SIMON family with reduced-round masking technique and it is shown that first round key recovery is possible through actual programming.

Objectives: To explore experiences of treatment-related side effects and supportive care among Korean breast cancer survivors (BCS). Methods: Focus group interview was conducted with six Korean women with breast cancer. Participants were recruited through snow-balling. Interview was audio-recorded and transcribed verbatim. NVivo-11 was used to code the data into themes. Results: Two major themes were identified: (1) experiences of Western medicine, including treatment, side effects, needs and costs; (2) experiences of supportive care with Korean medicine, including the same as above. All participants experienced Western medicine in treatment phase and reported impairment of physical, emotional, and social functioning during and after Western medicine treatment. Only three participants used Korean medicine after treatments end. The negative responses from Western medicine doctors were the most important factor keeping participants from accessing Korean medicine when treatment-related side effects occurred. For this reason, some participants used Korean medicine without disclosure. Participants usually acquired information about Korean medicine from online community or other BCS, which was another important factor because it raised concerns about side effects and credibility of Korean medicine. High cost was also reported as barrier in using Korean medicine. During the cancer treatment, participants tended to endure their treatment-related side effects. Conclusions: Korean BCS may be at high risk of physical or emotional distress during treatment period. Findings suggest that there is a high need for supportive care to relieve treatment-related side effects and improve patients' quality-of-life. Furthermore, developing a systematic guidance or credible information sources should be warranted to help patients find the best supportive care options including Korean medicine.

The tone reservation (TR) scheme is an attractive method to reduce peak-to-average power ratio (PAPR) in the filter bank multicarrier with offset quadrature amplitude modulation (FBMC-OQAM) systems. However, the high PAPR of FBMC signal will severely degrades system performance. To address this issue, a cyclic shift based TR (CS-TR) scheme with embedding side information (SI) is proposed to reduce the PAPR of FBMC signals. At the transmitter, four candidate signals are first generated based on cyclic shift of the output of inverse discrete Fourier transform (IDFT), and the SI of the selected signal with minimum peak power among the four candidate signals is embedded in sparse symbols with quadrature phase-shift keying constellation. Then, the TR weighted by optimal scaling factor is employed to further reduce PAPR of the selected signal. At the receiver, a reliable SI detector is presented by determining the phase rotation of SI embedding symbols, and the transmitted data blocks can be correctly demodulated according to the detected SI. Simulation results show that the proposed scheme significantly outperforms the existing TR schemes in both PAPR reduction and bit error rate (BER) performances. In addition, the proposed scheme with detected SI can achieve the same BER performance compared to the one with perfect SI.

Binary offset carrier (BOC) signal synchronization is one of the most important steps to recover the transmitted information in global navigation satellite systems (GNSS) including Galileo and global positioning system (GPS). Generally, BOC signal synchronization is based on the correlation between the received and locally generated BOC signals. Thus, the multiple side-peaks in BOC autocorrelation are one of the main error sources in synchronizing BOC signals. Recently, a novel correlation function with reduced side-peaks was proposed for BOC signal synchronization by Julien [8]; however, Julien's correlation function not only still has the side-peaks, but also is only applicable to sine phased BOC(n, n), where n is the ratio of the pseudo random noise (PRN) code rate to 1.023 MHz. In this paper, we propose a new correlation function for BOC signal synchronization, which does not have any side-peaks and is applicable to general types of BOC signals, sine/cosine phased BOC(kn, n), where k is the ratio of a PRN chip duration to the period of a square wave sub-carrier used in BOC modulation. In addition, an efficient correlator structure is presented for generating the proposed correlation function.

The emergence of smart phones has brought about a revolution in introducing a computer into the palm of a hand, and this revolution has lead to a smart society that offers comfort and joy in life; however, some side effects including a smart phone syndrome have been identified on a wider and more varied scale compared with any other IT devices of the past. This paper deduced side effect types and key issues according to type focusing on risk factors in accordance with the purpose of the use of smart phones, and diagnosed social effects based on them. In addition, based on the diagnosed results, the study proposed solutions to minimize side effects in order to produce social understanding and sympathy concerning the desirable utilization of smart phones. The proposed solutions should be able to cope with visible and potential side effects systematically by helping people to utilize smart phones, which are a platform of creativity, cooperation, communications, and entertainments, in a desirable way.

Recently, several cache side channel attacks have been proposed to extract secret information by exploiting design flaws of the microarchitecture. The Flush+Reload attack, one of the cache side channel attack, can be applied to malicious application attacks due to its properties of high resolution and low noise. In this paper, we proposed a detection system, which detects the cache-based attacks using the PCM(Performance Counter Monitor) for monitoring CPU cache activity. Especially, we observed the variation of each counter value of PCM in case of two kinds of attacks, Spectre attack and secret recovering attack during AES encryption. As a result, we found that four hardware counters were sensitive to cache side channel attacks. Our detector based on machine learning including SVM(Support Vector Machine), RF(Random Forest) and MLP(Multi Level Perceptron) can detect the cache side channel attacks with high detection accuracy.

A fineness range of 150 Nm-170 Nm has recently been applied to produce much finer wool products, so that processing techniques for the wool fabrics have been developed very rapidly. However, the worsted wool-like technique using polyester fiber has not been still implemented in general processing technique. Therefore, this research is to develop materials of side-by-side type with high finess, high shrinkage and stretchability. The mechanical properties of the produced fabrics were analyzed and the fundamental information were obtained for the new worsted wool-like products. The physical properties of a latent crimped yarns of side-by-side type with stretch function are analyzed. Also the mechanical properties of five kinds of fabrics are analyzed, which are produced with non-circular shape(+type) warp yarns of a twist of 1000(T/M) and with two kinds of latent weft yarns of a twist of 1000 T/M and DTY respectively.
