  • We survey the researches on self-reproducing structures on cellular automata. Self-reproduction is the foremost characteristic of life, and cellular automata are ideal model for studying artificial life. From the early studies by Von Neumann to late results on computational models using self-reproducing structures and emergence of self-replication are covered. Also possible applications of self-replicating structures are listed.

  • To realise the full benefits of a self-centering seismic resilient system, the designer must ensure that the entire structure does indeed re-center following an earthquake. The idealised flag-shaped hysteresis response that is often used to define the cyclic behaviour of self-centering concrete systems seldom exists and the residual drift of a building subjected to an earthquake is dependent on the realistic cyclic hysteresis response as well as the dynamic loading history. Current methods that are used to ensure that re-centering is achieved during the design of self-centering concrete systems are presented, and a series of cyclic analyses are used to demonstrate the flaws in these current procedures, even when idealised hysteresis models were used. Furthermore, results are presented for 350 time-history analyses that were performed to investigate the expected residual drift of an example self-centering concrete wall system during an earthquake. Based upon the results of these time-history analyses it was concluded that due to dynamic shake-down the residual drifts at the conclusion of the ground motion were significantly less than the maximum possible residual drifts that were observed from the cyclic hysteresis response, and were below acceptable residual drift performance limits established for seismic resilient structures. To estimate the effect of the dynamic shakedown, a residual drift ratio was defined that can be implemented during the design process to ensure that residual drift performance targets are achieved for self-centering concrete wall systems.

  • This essay reconsiders the subject of Romantic self-consciousness in a post-de Manian perspective. Self-consciousness is an attribute of Romantic lyricism whereby the poetic speaker I remains conscious of how (s)he feels or lives here and now. This self-reflective feature of Romantic poetry has been controversially interpreted either as self-centered solipsism or as self-expressive objectivism. The question is stirring more disputes among Romantic critics after the advent of New Historicism and Feminism. These two historicistic approaches reprove Romantic poetry for a lack of the sense of history and ascribes it to Romantic self-consciousness. They argue that Romantic poets in general displace historical materiality into an object of internal consciousness, so negating absurd social realities "merely to gain their own immortal soul." This essay targets to overcome this negative stance on Romantic self-consciousness with a "subversive" return to Paul de Man's criticism of Romantic internality.

  • The purpose of the present study is to compare the differences in levels per group of high school students regarding the self-regulated learning factors for mathematics. For this purpose, a self-regulated learning measurement tool was developed and surveys were conducted. And the statistical analysis was completed using the frequency analysis, Kolmogorov-Smirnov normality test, Mann-Whitney U test and the Kruskal-Wallis H test. As a result, it is found that self-efficacy is of statistically significant differences in self-regulated learning levels regardless of the group classifications but test anxiety does not show statistically significant differences in self-regulated learning levels regardless of the group classifications.

  • Self-sufficiency has been recognized as one of the most important welfare goals for women in the domestic violence field since the welfare reform in the U.S. A qualitative research design was conducted to explore the self-sufficiency experience of Korean-American single mothers with the history of domestic violence in poverty. The meaning of 'self-sufficiency' to participants is that a continuing task or process in life to move toward being independent mentally as well as economically. Their challenges toward self-sufficiency include the period of restoration of their potentials for self-sufficiency destroyed by domestic violence victimization and divorce, and the period of developing their sustainability for self-sufficiency. Their needs for 'help and support similar to care from the woman's parents' home', 'welfare service of select and concentration', 'mature dependency and self-sufficiency', and 'self-sufficiency from survival to dream come true' to cope with the challenges formentioned are reported. Concrete strategies for the development of self-sufficiency polices and services sensitive to immigrant single mothers with the history of domestic violence are suggested.

  • Objectives: Self-reported disease history is often used in epidemiological studies. In this study, we acquired the hospital records of subjects who self-reported stroke or myocardial infarction (MI) and evaluated the validity of the participants' self-reported disease history. We also determined the level of agreement between specialists and non-specialists. Methods: Among the participants in the Health Examinees study, 1488 subjects self-reported stroke or MI during 2012-2017, and medical records were acquired for the 429 subjects (28.8%) who agreed to share their medical information. Each record was independently assigned to 2 medical doctors for review. The records were classified as 'definite,' 'possible,' or 'not' stroke or MI. If the doctors did not agree, a third doctor made the final decision. The positive predictive value (PPV) of self-reporting was calculated with the doctors' review as the gold standard. Kappa statistics were used to compare the results between general doctors and neurologists or cardiologists. Results: Medical records from 208 patients with self-reported stroke and 221 patients with self-reported MI were reviewed. The PPV of self-reported disease history was 51.4% for stroke and 32.6% for MI. If cases classified as 'possible' were counted as positive diagnoses, the PPV was 59.1% for stroke and 33.5% for MI. Kappa statistics showed moderate levels of agreement between specialists and nonspecialists for both stroke and MI. Conclusions: The validity of self-reported disease was lower than expected, especially in those who reported having been diagnosed with MI. Proper consideration is needed when using these self-reported data in further studies.

  • This study is a life history on self-realization of woman in the abstinence of alcohol process. The purpose of the study is to explore the circumstance of female alcoholism, to expand the prospect of discussion for treatment and recovery, and to suggest social welfare intervention measures. The study involved a female alcoholic who had been recovering for more than seven years, and the text for life history analysis was divided into 'dimension of life', 'turning point' and 'adaptation' based on the life history analysis framework proposed by Mandelbaum. As a result of the data analysis, 'dimension of life' was analyzed into three areas, such as the personal level of life, the family level of life, and the social dimension. 'Turning point' is to escape from a father who drinks alcohol and uses violence, to give up his job to avoid boss's abuse, and to proceed one's own way of healing. 'Adaptation' was derived into good at studying, relieving anger by drinking alcohol, and referring to AA and self-realization. Based on these findings, this study presented the social welfare practice and policy discussion focused on self-realization.

  • Purposes : The Purpose of this study was to review a current status on acupuncture and traditional Chinese medicine in Canada focusing on the rules of regulatory bodies of 5 states including legislation history, development in professional self-regulation, education and evaluation system. Methods : Based on literature review, we studied on 5 legislated states cases, educational accreditation status and licensure system. We also interviewed on a person who is a chair of CTCMA & CARB-TCMPA and more TCM practitioners in British Columbia within educational topics. Results & Conclusions : Acupuncture legislations have been approved by the governments in Canada between 1988 and 2014 within the acceptance of self-regulation. Since then, regulatory bodies in each states have tried to strengthen their duties and rights as a healthcare professionals. Based on firm laws and regulations, occupational competency-based education in acupuncture and TCM has been gradually improved and established quite well in parallel with a development of higher educational system in Canada.

  • Purpose: The purposes of this study were 1) to compare the contribution of demographic-behavioral variables and psychological variables in explaining the variance of depression, 2) identify the most important predictors of depression for Korean female adolescents. Method: The participants were 840 female adolescents. Data was collected through self-report questionnaires, which were constructed to include demographic-behavioral factors, self-esteem, hostility, hopelessness, and depression. Data was analyzed using the SPSS program. Result: Female adolescents' demographic-behavioral variables explained 17% of the variance in depression, and perceived physical health status, history of physical abuse, smoking, satisfaction of body weight, parental alcohol abuse, parental divorce, and history of suicidal attempt were the significant predictors of depression for female adolescents. Psychological variables explained 50% of the variance in depression, and self-esteem, hostility, and hopelessness were the significant predictors of depression for female adolescents. The significant predictors of depression among female adolescents' demographic-behavioral variables and psychological variables were self-esteem, hostility, hopelessness, perceived physical health status, parental alcohol problem, and history of physical abuse, explaining 52% of the variance in depression. Conclusion: In order to reduce depression in female adolescents, it is necessary to design an intervention program that emphasizes improving self-esteem while reducing hostility and hopelessness.

  • A low damage self-centering braced frame equipped with post-tensioning strands is capable of directing damage to replaceable butterfly-shaped fuses. This paper investigates the seismic performance of rocking braced frame under near-field pulse-like ground motions compared to far-field records. A non-linear time history analysis is performed for twelve self-centering archetypes. A sensitivity analysis is carried out to examine the influences of ground motion types and modeling parameters. Findings represent the proper efficiency of the self-centering system under both far-field and near-field pulse-like ground motions.
