In this study, a generic intelligent wireless sensing platform with the IoT and wireless transmission technology is established for greenhouse monitoring, which is capable of greenhouse data collection and analysis. The data analyzed by a cloud server would provide important information regarding the efficiency of greenhouse management and cultivation methods. To monitor greenhouse related parameters, an embedded board is placed in a greenhouse as the gateway. Monitoring data and images collected by sensors deployed in the greenhouse are transmitted to the embedded board via an Ethernet or wireless transmission module. The data are eventually sent to a database by wireless AP. The AP connects to the internet by using a 4G USB dongle, which can provide sufficient data transmission speed for real-time data transmission. In wireless hotspots and areas with Wi-Fi, not only can images be transmitted to the cloud, but also can the mobile APP be used to perform remote monitoring, so experimental observations are no longer affected by geographical impacts. Moreover, to ensure the preservation of images and numeric data, the gateway carries a high durability secure digital (SD) memory card to store images and data; if the network encounters some problems, such as unable to connect and a lack of network traffic, the data can be stored in the SD card. Thus, the proposed platform is able to perform heavy information transmission duties and support performing all wireless monitoring tasks. In addition, the analyzed data can be used by agricultural personnel to provide critical cultivation suggestions.

Objective: Rumination is a maladaptive emotional-regulation strategy that is strongly associated with depression. Impaired executive function can lead to difficulties in disengaging from rumination, thus exacerbating depression. In this study, we inspect an electroencephalograph neurofeedback protocol that enhance the target peak alpha frequency (PAF) activation in the prefrontal region. We examine the protocol’s effects on depression and rumination. Methods: We randomly assigned 30 dysphoric participants into either the neurofeedback training group or the control group. We then evaluated their depression, rumination, and executive function at pre- and posttraining so as to examine the effects of the neurofeedback. Results: The results show that this neurofeedback protocol can specifically enhance participants’ target PAF. The participants’ executive function performances significantly improved after undergoing 20 neurofeedback sessions. Compared with those in the control group, those in the neurofeedback group had significantly fewer depressive symptoms and significantly reduced rumination. Moreover, as target PAF and executive function improved, depression and rumination both declined. Conclusion: Our data are in line with those of previous studies that indicated a relationship between upper-band alpha activity and executive function. This PAF neurofeedback can effectively enhance participants’ executive function, which can reduce rumination and ameliorate depression. This neurofeedback training is based on basic cognitive neuroscience, so it sheds light on depression’s pathological factors and etiology
Path Loss Exponent Estimation for Indoor Wireless Sensor Positioning

Rapid developments in wireless sensor networks have extended many applications, hence, many studies have developed wireless sensor network positioning systems for indoor environments. Among those systems, the Global Position System (GPS) is unsuitable for indoor environments due to Line-Of-Sight (LOS) limitations, while the wireless sensor network is more suitable, given its advantages of low cost, easy installation, and low energy consumption. Due to the complex settings of indoor environments and the high demands for precision, the implementation of an indoor positioning system is difficult to construct. This study adopts a low-cost positioning method that does not require additional hardware, and uses the received signal strength (RSS) values from the receiver node to estimate the distance between the test objects. Since many objects in indoor environments would attenuate the radio signals and cause errors in estimation distances, knowing the path loss exponent (PLE) in an environment is crucial. However, most studies preset a fixed PLE, and then substitute it into a radio propagation loss model to estimate the distance between the test points; such method would lead to serious errors. To address this problem, this study proposes a Path Loss Exponent Estimation Algorithm, which uses only four beacon nodes to construct a radio propagation loss model for an indoor environment, and is able to provide enhanced positioning precision, accurate positioning services, low cost, and high efficiency.

Objective: To explore the effect of portal vein chemotherapy on liver metastasis after surgical resection of colorectal cancer. Methods: Patients fulfilling the eligibility criteria were assigned to receive either surgery plus 1-week continuous infusion of 5-FU (study group) or surgery alone (observational group). Patients in the study group received portal vein chemotherapy, whereby 5-FU (1000 mg/d) and heparin (5000 IU/d) infusion was initiated from the day of surgery and lasted for 7 consecutive days. Liver metastasis was monitored during five years follow-up postoperatively. Results: Sixty four patients were recruited and assigned to the study group (12 with colon and 20 with rectal cancer) or the control group (10 with colon and 22 with rectal cancer). Liver metastasis rate was 12.5% in study and 25.0% in observational group, the difference being significant (P<0.01). Conclusion: Portal vein chemotherapy could be an effective treatment in preventing liver metastasis after surgical resection of colorectal cancer.
The Dark Side of Democratic Participation and Its Cures

민주주의의 교육적 기능은 건강한 민주주의를 재생산한다는 점에서 중요하다. 하지만, 우리는 이러한 배양을 당연하게 여겨서는 안 된다. 민주주의를 사고하는 측면에서 다른 요소들이 존재하기 때문인데, 그 의미는 사람들이 또 다른 민주적 교훈들을 배울 수 있다는 점이다. 이 에세이에서, 나는 민주주의 교육의 장이 직면하는 위험을 설명하기 위해 대만의 홍수 피해 지역의 사례를 사용한다. 나는 또한 홍수 피해 지역의 주민참여예산제도(PB)들이 교육 기능을 상실하는 이유를 요약한다. 진료소에서 홍수로 인한 지역 사건까지, 나는 이상적인 민주주의 교육의 장을 건설하고 민주주의 교육이 긍정적으로 순환되도록 되돌리기 위해서는 문화적 해결책이 가장 중요하다고 주장한다. The educational function of democracy is important for reproducing a healthy democracy. However, we should not take this reproduction for granted. Since there are different kinds of democratic imaginations, it means people may learn different democratic lessons. In this essay, I use the case of the Flooding district in Taiwan to illustrate the risk a democratic school faces. I also summarize the reasons why PB in the Flooding district loses its educational function. From the clinic to the case of the Flooding district, I argue that the cultural solution is most important for building an ideal democratic school and bringing democratic education back to a positive loop.
지능정보사회에서의 중국지역간 정보격차와 지각된 학업성과에 관한 연구

2000년대부터 중국 경제성장을 주도하는 핵심적 산업인 정보통신산업에 대해 집중적으로 육성 및 지원함으로써 정보통신기술의 사회적 확산도 매우 빠른 속도로 진전되었다. 그러나 정보통신 기술산업의 생산품과 개인 소득의 측면에서 지역 간의 경제성장이 빠른 지역과 그렇지 못한 지역간의 정보통신기술의 확산 속도 및 보급의 격차는 여전히 심한 것으로 나타났다. 또한 중국인터넷발전상황통계보고에 따르면 도시와 농촌의 인터넷 보급률을 살펴보면 보급률은 모두 증가세를 보이지만 격차는 여전히 큰 것으로 확인할 수 있다. 본 연구는 정보격차가 지각된 학업성과에 어떠한 영향을 미치는 지에 파악하고자 한다. 또한지역 간의 정보격차에 따른 지각된 학업성과의 차이가 존재하는 지에 확인하고자 한다. 향후 중국 지역 간의 정보격차를 해소할 수 있는 방안을 모색함으로써 교육성과를 제고하고 교육역량 활성화에 기여할 수 있는 것으로 기대된다.
