The nature of encoded information in neural circuits is determined by neuronal firing patterns and frequencies. This paper discusses the molecular identity and cellular mechanisms of spike-frequency adaptation in the central nervous system (CNS). Spike-frequency adaptation in thalamocortical (TC) and CA1 hippocampal neurons is mediated by the $Ca^{2+}$-activated $Cl^-$ channel (CACC) anoctamin-2 (ANO2). Knockdown of ANO2 in these neurons results in increased number of spikes, in conjunction with significantly reduced spike-frequency adaptation. No study has so far demonstrated that CACCs mediate afterhyperpolarization currents, which result in the modulation of neuronal spike patterns in the CNS. Our study therefore proposes a novel role for ANO2 in spike-frequency adaptation and transmission of information in the brain.

This study analyzes how the perceived pressures and organizational readiness of fashion companies (that utilize the internet as a marketing or commercial transaction tool) influence the continuous internet adaptation intention. It ascertains the differences between the companies that have introduced the internet commercial transaction and companies that have not. The survey was conducted among the employees of fashion companies from January $15^{th}$ to February $20^{th}$ in 2009. A total of 314 respondents were submitted for analysis using diverse methods that include frequency analysis, factor analysis, reliability analysis, t-test, and multiple regression analysis. The results show that the perceived internal and external pressures, the support of the chief executive officer and capacity of the organization influence the continuous internet adaptation intention of fashion companies. There are differences in the perceived internal and external pressures, support of the chief executive officer, capacity of the organization, and continuous internet adaptation intention between companies that introduced a internet commercial transaction system and those that have not.

In this paper, a sliding mode control method with uncertainty adaptation is proposed by introducing the virtual state. Because upper bound of the uncertainty is very difficult to know, we estimate this by using the simple adaptation law and design the sliding surface which has dynamic of nominal system. An optimal controller is used by nominal controller. And if initial values of the virtual state are chosen properly, the reaching phase is removed.

Purpose: This study was conducted to examine the adaptation experience of male nurses working in general wards. Methods: Experiential data was collected from 16 general ward nurses through in-depth interviews. Participants were selected from male nurses working in the general wards with over one year of clinical experience at a tertiary university hospital. The main question was "Can you describe your adaptation experience in the general ward as a nurse?" All interviews were recorded and transcribed, then analyzed using Colaizzi's method. Results: Four categories were derived from the analysis: 'difficulties from task adaptation by characteristics', 'limited nursing situation and circumstance as a male nurse', 'efforts to adapt at general nursing unit', and 'self-worth, and worry about something as a male nurse'. Conclusion: Male nurses had a difficulty adapting to work in wards due to lack of multi-tasking skills, as well as some social prejudice or negative views on male nurses. Establishing reasonable guidelines for male nurses in practice, promoting their responsibilities to patients, developing mentoring programs, and reassessing the policy of assigning male nurses to general wards are recommended to help in better adaptation.

Purpose: The purpose of this study was to check the stress, stress and coping ability of nursing college students and to identify factors that influence college life adjustment. Method: This study was a descriptive research study to confirm the correlation between stress, stress response, coping ability, and college life adaptation of nursing college students, and to analyze the factors that influence college life adjustment. The data collection period was from August 17 to 23, 2020, for one week, the researcher directly explains the purpose and purpose of the study to 221 nursing college students nationwide, and online surveys to those who have agreed to participate in the study. The collected data were analyzed using SPSS Win 20.0 program. Results: Adaptation to college was negatively correlated with stress (r=-.285, p<.001), stress response (r=-.258, p<.001), and coping ability (r=.512, p<.001) had a positive correlation. The most significant factor influencing the study subjects' adaptation to college life was coping ability (β=.473, p<.001), followed by stress (β=-.185, p=.002) in the order of The explanatory power of the factors affecting the subject's adaptation to college life was 28.9%. Conclusion: As a result of this study, it means that nursing students' adaptation to college life has less stress and stress response, and higher coping ability increases college life adaptation. The factor that influenced the adjustment to college life was the most significant factor, followed by stress. In order for nursing students to adjust to college life smoothly, it is thought that coping measures to reduce stress and stress responses and overcome them are necessary.

Purpose: On the basis of the theoretical framework of a combination of Roy's adaptation theory and Lazarus & Folkman's theory of stress - appraise coping, the purpose of this study was to predict effect factors of adaptation to university life of Chinese international students in Korea. After this, a model of adaptation to university life of Chinese international students in Korea was constructed. Methods: A questionnaire was used to survey 369 Chinese international students from one university in Korea, which was analyzed by using PASW Statistics 18.0 and LISREL 8.7. Results: This theoretical model explained adaptation to university life of Chinese international students at 75.0% in Korea. Physical symptoms, loneliness, acculturation stress and self-efficacy directly affected the adaptation to university life. Korean language proficiency indirectly affected adaptation to university life through self-efficacy. Conclusion: Results of this study provided theoretical basis for the future health care of university- centered health centers. For improving adaptation to university life of Chinese international students in Korea, education and nursing measures for reducing physical symptoms, loneliness and acculturation stress, and improving Korean language proficiency and self-efficacy are proposed for further research and development.

This study attempts to facilitate climate change adaptation in conservation area by spatial planning of climate adaptation zone for endangered species. Spatial area is South Korea and select leopard cat (Prionailurus bengalensis) as a target species of this study. In order to specify the climate adaptation zone, firstly, Maximum entropy method (Maxent) was used to identify suitable habitat, and then core habitat was selected for leopard cat. Secondly, land use resistance index was evaluated and least cost distance was analyzed for target species. In this step we choose dispersal capacity of leopard cat to reflect species ecological characteristic. Finally, climate adaptation zone is described and adaptation measures are suggested. The presented approach could be generalized for application into conservation planning and restoration process. Furthermore, spatial planning of climate adaptation zone could increase heterogeneity of habitat and improve adaptive capacity of species and habitat itself.

The purpose of this study was to investigate the relationship among bullying, ego-resilience, perceived stress and adaptation on college in nursing students. A total of 212 students from 1-4 grade in one nursing college were recruited into the study. The data were collected using questionnaire about bullying, ego-resilience, perceived stress and adaptation and were analyzed with PASW Statistics 18.0 program. Bullying and perceived stress had a significant negative association with nursing college adaptation(r=-.261, p<.001; r=-.261, p<.001) and nursing college adaptation was positively correlated with ego-resilience(r=.337, p<.001). The significant predictors of nursing college adaptation were grade(${\beta}$=-.216, p=.003), satisfaction with major(${\beta}$=-.245, p<.001), the latest semester grade(${\beta}$=.210, p=.028) and ego-resilience (${\beta}$=.324, p<.001), explaining 29.1% of the variance in nursing college adaptation(F=9.691, p<.001). According to the results, ego-resilience could be a key factor to improve college adaptation and bullying and perceived stress were associated with adaptation. Therefore many trials have to be need for enhancing college adaptation in a multiple and convergent way and it is suggested that the program to strengthen college adaptation should be developed.
