  • All over the world more and more attention is being paid to green management which enables environment-friendly sustainable development. To keep up with these global trends and in response to the government's "low carbon green growth" policy, many efforts are being made in the port and logistics in order to drastically reduce carbon emissions and save operating expenses. To this end, the engine power source of the cranes in the container terminal is being replaced with electricity from fossil fuel. Among those cranes, especially e-RTGC has been proved to be practical and excellent in its performance through many previous studies. However, no empirical study has yet been made on its introduction effects when e-RTGC has been introduced to the container terminal. In the meantime, however, many domestic container terminals have introduced e-RTGC, and so some data have been accumulated for further research. Under these circumstances, this study has tried to make an empirical study through the case study of D container terminal, checking the restriction factors to be considered at the time of eURTGC introduction, and analyzing its introduction effects and problems. We have high expectations that this study will provide key consideration factors and empirical analysis data to the decision makers who plan to introduce an e-RTGC system, and also will be used as a reference to the development direction of e-RTGC.

  • The purpose of this study is to examine the effects of short-term foresters on brain waves and pulse waves. For this purpose, 484 foresters who visited the natural recreation forest located in Cheongpyeong city, Gyeonggi province, measured the before and after experiences of EEG and pulse waves, and the following results were obtained. First, foresters have been shown to be effective on concentration, brain activity, and brain stress. Second, foresters had positive effects on cardiac health and autonomic health. In other words, when various substances released from the forest come into the body through the respiratory system, it firstly affects the heart activity positively, and it seems to be able to expect various improvements by acting on the emotional side of the brain. Therefore, based on the scientific basis of the forest experience, it is expected that the experience of forests will be widely used as a guide for healthy life by creating conditions for participation by many people. In addition, the mechanism of respiration, heartbeat, and brain interaction is also possible, and various experimental studies on the forest experience in the future are important.

  • Recently, a smartphone manufactured on a flexible substrate has been released as an electronic device, and research on a stretchable electronic device is in progress. In this paper, a silicon-based stretchable material is made and used as a substrate to implement and evaluate an optical sensor device using oxide semiconductor. To this end, a substrate that stretches well at room temperature was made using a silicone-based solution rubber, and the elongation of 350% of the material was confirmed, and optical properties such as reflectivity, transmittance, and absorbance were measured. Next, since the surface of these materials is hydrophobic, oxygen-based plasma surface treatment was performed to clean the surface and change the surface to hydrophilicity. After depositing an AZO-based oxide film with vacuum equipment, an Ag electrode was formed using a cotton swab or a metal mast to complete the photosensor. The optoelectronic device analyzed the change in current according to the voltage when light was irradiated and when it was not, and the photocurrent caused by light was observed. In addition, the effect of the optical sensor according to the folding was additionally tested using a bending machine. In the future, we plan to intensively study folding (bending) and stretching optical devices by forming stretchable semiconductor materials and electrodes on stretchable substrates.

  • Due to COVID-19, non-face-to-face cultures such as remote classes, remote work, and tele-medicine are spreading. The major contributors to the settlement of such a non-face-to-face society are small and medium SW companies and SW manpower. However, recently as large platform companies and foreign big tech companies hire thousands of SW manpower, SW small and medium-sized companies are experiencing a serious manpower shortage. Therefore, the purpose of this study is to suggest policy alternatives for SMEs to stably secure SW manpower and support continuous business operation. To achieve this purpose, this study examines the current status of the SW industry and manpower, then summarizes related issues and suggests policy alternatives to solve these issues. Those policies include the reinforcement of incentives to support manpower retention such as the Naeil Chaeum deduction system, youth housing union composition, special military service system, recruitment of manpower through the contract semester system of employment conditions, reinforcement of customized education through supplementation of the SW manpower training voucher system, SW field skill standardization, establishment of a governance system for nurturing SW manpower, preparation of countermeasures against the outflow of manpower to large companies, and a win-win cooperation program for large and SME SW manpower.

  • The unprecedented pandemic of infectious diseases called COVID-19 has dampened human and material movement, and changes in the global economic structure have caused various economic and industrial problems such as worsening employment along with the domestic and international economic recession. In this crisis situation, the government announced the "New Deal" as a new card to enhance economic vitality following the "emergency disaster support fund." This means that the first business of the Digital New Deal, the beginning and core of the New Deal, begins digital transformation from collecting data, which is the "rice" of digital transformation to the data dam. Until now, not only the government but also local governments have established and operated platforms for collecting and sharing public data by establishing various data portals. It is evaluated that it lacks utilization for commercialization as not only the government but also local governments focus only on building the platform without considering the business model when building the initial public data platforms. In particular, in the case of regions, there is a lack of public data to be used for data business, so it is necessary to utilize data from public institutions in the region. In this study, various data collection, data quality improvement, and data utilization improvement were suggested as measures to solve these problems.

  • The purpose of this study is to find out how those taking early childhood preservice teachers experience their learning through learner-centered education and the meaning given by such experiences to grasp their values. Especially, to look into experiences of learning the project approach theory studied and directly experienced, which is one of the early childhood educational approach methods, data on participatory observation, personal interviews, personal reflective journals, activity reports and ect. were collected and analyzed by the current writer, who fully participated in the class. The meaning of early childhood preservice teacher'experiences in the project approach was analyzed from the two aspects of 'my' learning activities and 'teacher's teaching activities. In the aspect of 'my' learning activities, they got indulged through purposeful practices in the process of tackling problems that originated from personal interest and wanted to share the joy of learning they'd had with others. Aware of themselves as doers of behavior and thinking, they were found to be able to focus an 'my' own learning activities based on these learning experiences of theirs. In the aspect of 'teacher's teaching activities, project theories and practices done at the same time helped them internalize the project and they learned possible changes ign the project by experiencing actual cases. To sum up, the project approach has its meaning in that it not only helps teachers learn theoretical knowledge but also have reflective thinking through their experiences as doers of learning and form practical knowledge. Accordingly, it indicates th need for intensive discussion on the project approach as a way to educate pre-teachers or current ones.

  • The cycle of human life has a limited time to death. Everyone cannot help but think how to live in the limited time and then they try to reach toward their happiness. Their pursuit for the happiness gives rise to the new trend called 'Well-bing'. Generally speaking, it means to eat well, to feel their own satisfaction with their lives and to spend a time on doing what they want to do. However, considering their current lives which are tough and harsh, it could be impossible for them to accomplish the well-being stated above. From this point, it is natural to think what real well-being means. Its real meaning would be understood by identifying its cause if well-being is the way to happiness. Based on the thesis stated above, let me look into the desire of human being. It has both side; it should be eliminated or overcome as a deficiency and disability in human life while it could be an driving force to let the human being keep their lives. They can find the real meaning of well-being and their happiness can be realized through the control of their desires. Above all, according to the control for them, they can accomplish their happiness or fail to do it. The trend of well-being can be kept in our culture when moral value is reflected to the well-being. Finally, it orients to the purpose of happiness. It also means that everyone shares moral and positive value one another in the process of challenge to achieve their goals. In order to realize it, they should be satisfied with their current situation and have a balance with everything related to themselves.
