The working situation has been dramatically changed in 2020 due to COVID-19. The purpose of this study is to identify the lighting environment which can be adapted to various styles of work from home. In this study, questionnaire survey and field measurement were conducted to identify the actual working situation and the lighting environment of the working location at home. This paper reports the results of questionnaire survey and the measurement data comparing the working location in office and at home.

In Situ Stress Measurement

Jixi mine area is one of the early mined areas in China and it's a typical deep mine. Because of large deformation of underground roadway and dynamic disasters occurred frequently in this mine, five measurement points of in-situ stress in this mine was measured and then analyzed with inversion. Based on these in-situ stress measurement data, numerical model of 3D in-situ stress back analysis was established. According to different stress fields, related analytical samples of neural network were given with FLAC program. Through the determination of hidden layers, hidden nodes and the setting of parameters, the network was optimized and trained. Then according to field measurement of in-situ stress, back analysis of initial stress field was conducted. Compared with field measurement, with accuracy requirement satisfied, it shows that the in-situ stress of rock mass obtained is basically reasonable. Meanwhile, it proves that the measurement of in-situ stress can provide deep mines with effective and rapid means, and also provide reliable data to optimization of deep roadway layout and supporting design.

The coronavirus disease (COVID-19) pandemic has become a “major disaster” for Indonesia. Communities became confused after the Government instructed people to “Stay at Home” and “Work from Home” in order to end the spread of the coronavirus. Many people feel that the Government's decision is detrimental because not everybody can work from home. There were many employee reductions in several companies and did not have a steady income. This study attempted to find out the use of Instagram as one of the popular media during the COVID-19 pandemic in Indonesia on economic impact. This study employed the semiotics method to analyse the #stayathomeindonesia hashtag on Instagram from 20 March 2020 to 5 April 2020. It was revealed that during the COVID-19 pandemic, Indonesian Instagram users used the platform to post their activity at home. Indonesian behaviours on Instagram amid the COVID-19 pandemic include posting homemade food, children’s drawings or colourings at home, and food order through online applications. So that the online-based economy more benefited than the offline-based because of limited activities outside the home due to appeals for staying at home.

Abstract Purpose: A retrospective observational study was carried on to investigate whether UV lamp will increase the risk of eye damage by comparing the exposure factors leading to ultraviolet keratitis (UVK) during the epidemic of COVID-19 and the control group in 2019.Methods: Data on UVK patients with clear exposure histories and typical symptoms were gathered. The date acquisition refers to the most crucial period in fighting the COVID-19 pandemic (24 January to 29 February in 2020, crucial period for short) in China, while the equivalent control 37- day period in 2019 refers to the period from 4 February to 12 March (control group for short). The detailed information of UVK cases were gathered through questionnaire survey, including injury photosources, ultraviolet applications, onset locations. Results: This retrospective observational study of 81 patients revealed that the number of UVK cases during crucial period 1 was threefold higher (n=61 patients) than control group (n=20 patients). All cases who recorded injury photosources were injury by UV lamps during crucial period, while by UV lamps (61.54%) or welding (38.46%) during control group. There were more than 70% of UVK cases injured at home by household UV lamps during crucial period, while were 15.38% during control group. They are significant differences in UVK photosource and exposure location between 2 groups (P<0.001).Conclusion: Household UV lamp users should be informed about possible UVK risk and of relevant preventive measures. Government and media should guide people use household disinfection items rationally and safely.

Corona Virus Disease 2019 (COVID-19) pandemic that hits Indonesia makes leading Indonesian government take policy measures by launching regulations in implementation procedures within government agencies. LIPI issued a circular to promote Increasing Awareness and Prevention of Spreading of COVID-19 Infection within LIPI’s offices environment. The LIPI Scientific Documentation and Data Center (PDDI) received this mandate to carry out and regulate the policy for carrying out official duties at home (WFH). This paper aims to describe the implementation of the policy of carrying out official duties at home (WFH) for librarians in the PDDI LIPI. Implementation of this policy shows that as an implementing institution unit, PDDI follows up on the policy by issuing work from home assignments with provisions that refer to the circular of the head of LIPI. The target group in this policy is librarians in LIPI. This paper applies descriptive writing with quantitative data approach. The results of this study indicate that principally, the objectives of this policy have been achieved. The target group optimally carries out official duties at home. The survei shows that the target group has implemented the policy in accordance with the direction of LIPI Chairman. The communication pattern and interaction between the policy implementer and the elements implementing the policy are relatively good, so that the policy can be implemented as expected. Communication media is very flexible and not rigid, information related to policies, policy changes are conveyed through the WhatsApp group communication channel so that librarians can immediately receive the policy information. In this policy implementation model, the implementing organization minimizes the factors that make this policy not properly implemented, namely by arranging picket schedules, providing official vehicles for those who do not have private vehicles and lending work facilities to be brought home.

Covid-19 pandemic has brought challenges in the process of history learning in senior high schools. As a result of social distancing and work from home policies, online learning platform is needed in order to make learning process at home run well, one of which is by using Quipper School application. The use of Quipper School application is one of the solutions so that the process of history learning at home can be carried out well and efficient during the Covid-19 pandemic. This study aims to determine the use of Quipper School in history learning during the Covid-19 era. The method used in this study is analytical descriptive method through literature review. The results obtained showed that Quipper School application has a positive impact when it is used in the process of history learning at home for students who are at senior high school level. The Quipper School application offers an innovative way of learning where the teacher can manage assignments and homework more effectively so that the teacher can also recognize the strengths and weaknesses of students in capturing a given learning topic.

Problems often exist in construction of transportation tunnels, such as the effect of new tunnels constructed close to existing structures. Solving this magnificent problem by carefully choosing tunnel construction methods will be beneficial to minimize effects on existing structures while ensuring the newly constructed tunnel is both time-consuming and economical. Three representative engineering methods-the benching tunneling method, the Center Diaphragm method and the Cross Diaphragm method-are compared in controlling the settlement of new tunnel vault and the deformation of the existing tunnel. Finally checking the simulation results by comparing with field measurement data.
