This paper reports on an ongoing study that utilizes the literacy autobiographies of 10 Asian and 10 Western graduate students from TESOL Masters programs in Korea and America as data for a cross cultural study on the discursive process of identity formation and the development of critical consciousness (Freire, 2000). While the data suggests similarities and differences between cultures in terms of the effects of education, social relationships, media, and religion, no definitive claims may be made due to the small size of the research corpus. However, analysis of the data revealed that only four of the narratives could be judged as engaging in critical introspection of individual subjects systems of knowledge, values, and beliefs, as opposed to the other narratives that were primarily descriptive of individual personal experiences. As such, this study found that while the willingness and ability to engage in the critical practices which lead to the development of a critical consciousness are similar across cultures, they may be mediated by the literacy practices inscribed in education, media, and other social practices.

Background: Breast and cervical cancers are significant causes of mortality and morbidity for Asian women, and poor English-speaking ability is a barrier to cancer prevention practices. Materials and Methods: This project tested relationships among English-speaking ability and early detection practices regarding to breast and cervical cancer among female Chinese immigrants. A descriptive cross-sectional survey was used. Results: 175 female Chinese immigrants completed the survey in the breast cancer prevention section, and 35 of them also completed the cervical cancer prevention section. Some 63% of them had heard about the clinical breast exam (CBE), but only 54% had had a CBE. While 46% of the participants were aware of their need for a Pap smear, only 31% had heard about it and had undergone a pelvic exam. Conclusions: English-speaking ability was strongly associated with immigrant women's knowledge of female cancer early detection. Culturally and linguistic issues should be considered as the first step to access immigrant population in designing future education intervention.

Blockchain interoperability, which refers in particular to the ability to access information across blockchain systems, plays the key role for different blockchains to communicate with each other, and further supports the superstructure built on top of the cross-chain mechanism. Nowadays, blockchain interoperability technology is still in its infancy. The existing cross-chain scheme such as BTCRelay requires that the smart contract in a blockchain to download and maintain block headers of the other blockchain, which is costly in maintenance and inefficient to use. In this paper, we propose a supervision mechanism between blockchains, called Surveillant. Specially, the new entities called dual-functional nodes are introduced to commit the real-time information from the blockchain under supervision to the supervising blockchain, which enables users to have efficient cross-chain verification. Furthermore, we introduce Merkle mountain range for blocks aggregation to deal with the large-scale committing data. We propose the design of long orphan branch counter to trace the bifurcations in the blockchain under supervision. The existing incentive mechanism is improved to encourage the behaviors of dual-functional nodes. In Surveillant, the analysis and experimental results demonstrate that users are able to have efficient cross-chain verification with low maintenance overhead.

Purpose: The purpose of this study was to explore the relationships of critical thinking disposition (CT), nursing work environment (NWE), and clinical decision making ability among nurses. Methods: A cross-sectional, descriptive study design was conducted on 192 nurses who had worked for more than six months in five general hospitals. A self-reported questionnaire was used to collect data, which included demographics, CT, NWE, and clinical decision making ability. Results: The mean score of CT was 3.5. The highest score was on the objectivity of CT and the lowest on systematicity. The mean score of NWE was 2.3. The highest score was on the collegial nurse-physician relations of NWE and the lowest on the staffing and resource adequacy. The mean score of clinical decision making ability was 3.3. In hierarchical multiple regression, affecting factors on clinical decision making ability were CT and NWE. Conclusion: The findings showed that clinical decision making ability is associated with CT and NWE. To improve clinical decision making ability, it is important to improve CT. In addition, it should be considered to improve NWE where the nurses can make a decision with their job through critical thinking.

Quantitative trait loci (QTLs), which were related to the ability of callus induction and plant regeneration in seed culture of rice, were analyzed using a mapping population from a cross between the rice cultivars 'Samgang' (tongil type) and 'Nagdong' (japonica). A tongil type rice cultivar, 'Samgang' showed lower frequency (20%) of plant regeneration than that (35%) of japonica rice, 'Nagdong'. Transgressive segregations were observed for the ability of callus induction and plant regeneration from the seed-derived calli of 58 doubled haploid (DH) lines. The ability of plant regeneration of 58 doubled haploid lines showed a continuous distribution with comparatively wide range (10.0 to 66.7%) of variation. Composite interval mapping analysis was used to identify the QTLs controlling callus induction and plant regeneration ability. Four significant QTLs, qCWS6, qCWS8, qCWS9 and qCWS11, associated with callus weight per seed were detected on chromosomes 6, 8, 9, and 11 with LOD values of 3.30, 2.60, 2.70 and 2.43, explaining 36% of the total phenotypic variation. Three significant QTLs, qPR1, qPR6, and qPR11, for the ability of plant regeneration were located on chromosome 1, 6, and 11 at LOD score of 2.25, 2.15 and 2.55, accounting for 24 % of the total phenotypic variation. The present study should be useful for improving the efficiency of plant regeneration in tissue culture of indica rice by means of marker-assisted selection.

Purpose: This study aimed to explore professional autonomy, nursing work environment, and clinical decision making ability and to determine predictors of clinical decision making ability among clinical nurses. Methods: A cross-sectional design was used in this study and 263 clinical nurses were selected from advanced-level hospitals with over 500 beds located in D metropolitan city. Independent t-test, ANOVA, Pearson's correlation coefficients and hierarchical multiple regression analyses were done with the SPSS/WIN 20.0 program. Results: Clinical nurses reported moderate levels of professional autonomy, nursing work environment and clinical decision making ability. Marital status, professional autonomy and nursing work environment accounted for 25% of variance in clinical decision making ability required in various clinical settings. Importantly, being married, higher level of professional autonomy, and greater satisfaction with work environment were significantly associated with better decision making ability. Conclusion: Findings indicate that improving the quality of decision making in the healthcare settings requires awareness of the multiple effects of individual, occupational and environmental features. Nurses' ability to make effective clinical decisions may rely on personal characteristics, the degree of autonomy in their job, and nurses' satisfaction with their work environment.

Purpose: The purpose of this study was to investigate the relationships among critical thinking disposition, problem solving ability, and triage competency in nurses working in Emergency Rooms (ERs). Methods: This cross-sectional study, conducted in August and September 2021, involved 118 ER nurses from three hospitals in the Gyeonggi-do metropolitan area. The data were analyzed using t-test, ANOVA, Scheffé test, Pearson correlation coefficients, and multiple linear regression analysis using SPSS for Windows version 25.0. Results: The mean score of triage competency among ER nurses was 87.63±15.65. In the regression model, age, ER experience, triage experience, critical thinking disposition, and problem solving ability predicted 52% of the triage competency. Both critical thinking disposition and problem-solving ability were noted to be significant (β=.32, p<.001; β=.36, p<.001, respectively). Conclusion: Critical thinking disposition and problem solving ability of ER nurses were identified as major factors in triage competency. To improve ER nurses' triage competency and enhance critical thinking disposition and problem solving ability, a systematic and ongoing program should be developed and implemented.

무선 네트워크의 사용이 모바일 사용자로 점점 확대되고 무선 네트워크 기술의 발달로 다양한 무선 네트워크 시스템이 생겨났다. 무선 네트워크 시스템들은 중첩되어 있을 수 있으며 네트워크 간 전환을 필요로 한다. NGWN(Next Generation Wireless Networks)은 다양한 무선 네트워크를 통합하여 사용자에게 넓은 커버리지 영역과 최적화된 서비스를 제공한다. 기존의 핸드오프 관리 프로토콜은 NGWN의 응용프로그램에 핸드오프 지원을 보장하기에 충분하지 않다. CLH(Cross-Layer Handoff) 프로토콜 기법은 NGWN의 네트워크 내와 네트워크 간의 효율적인 핸드오프 관리를 위해 개발되었다. CLH은 무선 네트워크 환경에서 이동성관리를 지원하고 핸드오프 성능향상을 위해 모바일의 속도와 핸드오프 시그널링 지연 정보를 이용한다. 본 논문에서는 핸드오프 성능 분석을 위해 링크계층 및 네트워크계층의 민감도를 분석하고 이것을 기반으로 CLH 기법을 제안한다. CLH가 네트워크 내와 네트워크 간 핸드오프의 성능 향상을 높여준 다는 것을 본 논문의 다양한 이론적 분석을 통하여 평가하고 분석한다.
