  • Punctured convolutional codes increase transmission efficiency without increasing hardware complexity. However, Viterbi decoder supporting punctured codes requires long decoding length and large survivor memory to achieve sifficiently low bit error rate (BER), when compared to the Viterbi decoder for a rate 1/2 convolutional code. This Paper presents novel architecture adopting a pipelined trace-forward unit reducing survivor memory requirements in the Viterbi decoder. The proposed survivor path architecture reduces the memory requirements by removing the initial decoding delay needed to perform trace-back operation and by accelerating the trace-forward process to identify the survivor path in the Viterbi decoder. Experimental results show that the area of survivor path unit has been reduced by 16% compared to that of conventional hybrid survivor path unit.

  • The purpose of this study was to explore factors influencing quality of life among cancer survivors in order to identify strategies for cancer survivors to go back to normal life and carry on stable and high quality life. This study used Korea National Health and Nutrition Examination Survey(2010-2014), conducted by Korea Centers for Disease Control and Prevention(KCDC). The sample of this study was 610 cancer survivors and their average time since diagnosis was about 11 years. The most powerful influencing factors for quality of life among cancer survivors were activity limitation(${\beta}$=.30, p<.001), followed by age(${\beta}$=-.20, p<.001), subjective health status(${\beta}$ =-.19, p<.001), and economic status(${\beta}$=.12, p=.004). According to the result, limitation on daily activities or social activities due to physical or mental debilitation was a strong factor that lowers quality of life among cancer survivors. Hence, there is a need for manpower and infrastructure that facilitates, supports, and manage daily activities of cancer survivors.

  • The purpose of this study was to explore 1) the illness experiences, 2) health behaviors (causal thoughts), and 3) health beliefs (health behavior changes after cancer diagnosis) among Korean breast cancer survivors using focus groups, which is a form of qualitative research methods. Thus, this study intended to understand how the illness experiences and health beliefs are associated with health behaviors. Three focus groups composed of 16 breast cancer survivors living in Seoul and GyeongGi were conducted with 5 to 6 people in each group. For illness experiences, health beliefs, and health behaviors of breast cancer survivors, some major themes related to physical, behavioral, psychological, and social domains were identified. Understanding health beliefs and health behaviors for Korean breast cancer survivors will be an important step toward developing social work interventions for enhancing health promotion.

  • With advances in health care, the cancer survival rate has significantly increased. Even though cancer treatment has finished, cancer survivors may continuously suffer from physical and psychosocial problems. In order to investigate the problems cancer survivors have experienced, a comprehensive rehabilitation program must be developed. This study sought to determine the content and structure of rehabilitation programs for cancer survivors, analyze the effectiveness of such programs, and develop a basis for future comprehensive rehabilitation program development. Through this review, thirteen programs were selected and classified according to exercise, psychosocial, and integrated or comprehensive aspects. Exercise programs improve physical function, fatigue, and hormone-related cancer effects. Psychosocial programs improve quality of life, mood changes such as depression, anxiety, and post traumatic factors. Comprehensive programs improve both physical and psychosocial aspects.

  • The purpose of this convergence study was to evaluate and to identify predictors of health-related quality of life(HRQoL) of families with cancer survivor(FCS) focusing on the comparison of families with cancer patient(FCP) receiving treatments. The research was conducted with the data for 153 FCS and 115 FCP taken from the 6th wave of the Korea National Health and Nutrition Examination Survey. The independent variables included socio-demographic, health related, psychological and social factors. The data were analyzed by hierarchical multiple regression analysis using SPSS/WIN 18.0. The results showed different patterns of predictors on the HRQoL of FCS and FCP. In FCS, the statistically significant factors were stress(${\beta}=-.192$, p<.05) and exclusion from economic activities(${\beta}=-.191$, p<.05). Therefore, families of cancer patients also need appropriate interventions for each stage of the disease.

  • The purpose of this study was to examine the impact of socioeconomic status on quality of life(QOL) among breast cancer survivors. The data were from breast cancer survivors in their forties, among whom the prevalence in terms of age was the highest in Korea. A total of 607 cases were analyzed and the mean scores of QOL measured by FACT-B were 93.75(SD=21.50). After controlling for the other socio-demographic and medical variables, QOL was significantly correlated to income and job type, which confirms the association between high socioeconomic status and better QOL. Specifically, groups with higher income($${\geq_-}4$$ million won/month, ${\beta}=0.11$, p= .03) and groups with self-employed(${\beta}=0.10$, p= .01) or professional/managerial(${\beta}=0.17$, p< .001) job type showed significantly better QOL. The need for more attention and support, including formal and informal resources, for breast cancer survivors with low socio-economic status and the implication for practice were discussed.

  • The purpose of the study was to analyze the concept of happiness that would be experienced in life of Korean cancer survivors. The concepts of happiness were analyzed using the Rogers' evolutionary concept analysis method for 11 papers satisfying the selection criteria, among domestic journals published from January 2000 to September 2017. The result of this study was that attributes of happiness were subjective experience, positive mind, meaning of life and formation of relationship. Antecedents were to accept-risk-of-life, cope-with-the-reality, implement-self-reflection and environmental-support. As a result of the concept, cancer survivors' inner strength increased, they became feeling love and pursuing new lives, and felt happiness through self-realization. This study is valuable to suggest a basic framework for the stepwise assessment that can improve the happiness of Korean cancer survivors and cancer survivors should be managed through multidisciplinary convergence programs.
