The purpose of this study is to demonstrate the antecedent and consequential factors of satisfaction with the flexible working system. Organizational culture was examined as an antecedent factor, while job satisfaction, work performance, organizational commitment, turnover intention, and quality of life were examined as outcome factors. The data of 2,785 public officials who used the flexible work system in the Korea Institute of Public Administration (2022) data set were analyzed using SPSS 28.0. and PROCESS macro's Model 4. The main research findings are as follows. First, organizational cultures that respect individuality and cooperation, supports management, and aims for work autonomy all positively and significantly affect satisfaction with the flexible working system. When ranking the size of influence by the type of organizational culture, work autonomy, respect for individuality, and a cooperative organizational culture had a positive impact in that order, with work autonomy being the most influential factor. In addition, the public officials' age, job preparation period, self-evaluation of workload, and overtime working hours are significant antecedents of satisfaction with the flexible work system. Second, when examining consequential factors, a high level of satisfaction with the flexible working system affects job satisfaction (+), work performance (+), organizational commitment (+), turnover intention (-), and quality of life (+). Job satisfaction was an especially valid mediator between satisfaction with the flexible working system and other consequential factors, including work performance, organizational commitment, turnover intention, and quality of life.

Background: This descriptive study aimed to examine the relationship between the 4C core competencies and work ability among dental hygienists. Methods: From November 2018 to January 2019, data were collected-from 190 dental hygienists workong in dental clinics in Busan, Ulsan, and Gyeongsangnam province using structured questionnaires. For the general characteristics of the dental hygienists, frequency and percentage were calculated, and the level of the 4C core competencies and work ability of dental hygienists was calculated using means and standard deviations. A multiple regression analysis was conducted to analyze the effects of the 4C core competencies on work ability. Results: The mean scores for the 4C core competency levels of the dental hygienists were as follows: communication ability 3.34, critical thinking ability 3.41, creative problem-solving 3.40, and collaborative self-efficacy 3.27. Meanwhile the mean score for work ability level was 3.65. The predictive factors influencing work ability were communication ability and cooperative self-efficacy (p<0.001), and the sub-factors of critical thinking ability that affect work ability were sound conferences (p<0.01), intellectual fairness (p<0.05), intellectual enthusiasm (p<0.05), and self-confidence (p<0.001). Finally, the sub-factors of creative problem-solving ability that affect work ability were planning and execution (p<0.01) and performance evaluation (p<0.05). Conclusion: The current study showed that education programs covering the core competencies of dental hygienists, rather than the existing theoretical education program, should be developed and implemented to enhance 4C core competencies that affect work ability.

해외도시개발은 선진국이 해외시장을 개척하고, 개도국이 당면한 도시문제를 해결할 수 있는 바람직한 솔루션임에도 불구하고 위험성이 높다. 선진국과 개도국은 서로간에 잘 알지 못하기 때문에 위험성이 높은 과업을 착수하기에는 신뢰가 부족한 경우가 있다. 본 연구는 양자 간의 신뢰를 향상시킬 수 있는 협력 프레임워크를 구축하고자 한다. 결론적으로 신뢰구축을 위해서는 작은 규모라도 협업을 반복하는 경험을 쌓는 것이 중요하다. 신뢰의 감정은 카리스마와 공감이라는 기제를 통해 구축할 수 있다. 카리스마는 반복적인 성공과 성과에 대한 지속적인 노출이 중요한 역할을 하며, 공감은 공동작업과 공간의 공유가 중요하다. 이것은 협업이라는 공통점을 가진다. 다섯 개의 해외도시개발사례를 분석하여 카리스마와 공감의 기제를 적용하였으며 이를 통해 해외도시개발 협력 프레임워크를 구축하였다.

In this research, we observed the co-works among novice and expert science teachers who were involved in a science teacher association and explored their interactions. The science teacher association is K-12 science teachers' gathering near Seoul. This study is a case study with the participant observation and the private interview of 8 novice teachers and 3 expert teachers. Based on the collected data, interaction between novice and expert teachers was categorized as seven types; question and answer, demonstration, presentation, co-working, providing materials, listening, and showing interest. Several factors supporting such an active interaction were derived from this study; 1) Teachers perceived well about the importance and the merits of co-working with other science teachers. 2) The open and cooperative environment of the science teacher association supported teachers' interaction. 3) There were tasks that teachers needed to co-work such as the science fair and the science camp. 4) There were opportunities of interactions for publishing books and developing modules. 5) Lots of expert teachers were willing to help and co-work with novice teachers. We found that novice teachers could continue to grow in terms of the professional development under interactive, continuing and cooperative environment with expert teachers.

Narrowband interference can severely degrade the performance of GPS receivers. Detecting the presence of interference and then characterizing it can lead to its removal. Receivers can be reconfigured to focus on other signals or satellites that are less vulnerable to that interference at that moment. Using hardware reconfigurability of FPGA receivers and characterizing the effect of narrowband interference on the GNSS signal quality lead us to a new RFI mitigation technique in which the highest quality and less vulnerable signal can be chosen at each moment. In the previous work [1], the post processing capability of a software GPS receiver, has been used to detect and characterize the CW interference. This is achieved by passing the GPS signal and the interference through the correlator. Then, using the conventional definition of C/No as the squared mean of the correlator output divided by its variance, the actual C/No for each satellite is calculated. In this work, first the 'Exclusion zone' for each satellite signal has been defined and then by using some experiments the effects of different parameters like signal power, jamming power and the environmental noise power on the Exclusion zone have been analyzed. By monitoring the Doppler frequency of each satellite and using the actual C/No of each satellite using the traditional definition of C/No and actual data from a software GPS receiver, the decision to reconfigure the receiver to other signal can be made.
