Purpose: Microcystic adnexal carcinoma is a rare malignant appendage tumor, first described by Goldstein et al in 1982. Here, we present our experience in treatment of a case on the lower lip. Methods: A 52-year-old female with an asymptomatic nodule on the chin, previously misdiagnosed as trichoadenoma by needle aspiration biopsy, was treated by wide excision combined with multiple circumferential frozen biopsies. Results: Pathological examination revealed typical features of microcystic adnexal carcinoma, such as basaloid and squamous cells forming nests and cord-like patterns, horn cysts, and minimal cytologic atypia. The patient has been followed up for 6 months. No sign of recurrence is noted to date. Conclusion: Differentiation from other benign adnexal neoplasms is important for its appropriate treatment. Differentiation can be difficult histologically because it is difficult to acquire an adequate biopsy due to its invasiveness, and clinically due to its asymptomatic and slow growing features. Complete excision is the key treatment, but it may not always be the best solution considering the huge defect that may result and the low incidence of metastasis & deaths owing to the tumor. We add this case to the approximately 300 cases reported worldwide with a review of literature.

Postoperative temporal hollowing is a common complication of craniotomy. Damage and repositioning of the temporalis muscle can lead to a depression in the temporal side of the skull with inferior bulging, worsening aesthetic outcomes. We report a case of cranioplasty with three-dimensional (3D) printed mesh involving an additional correction using a temporalis muscle sling to help address this problem. A 3D-printed bioabsorbable mesh was prepared based on preoperative facial computed tomography, and was fixed to the hollowed area for tissue augmentation. The temporalis muscle was elevated and fanned out to its original position, and a sling was attached to a screw that was fixed to the mesh. For reinforcement, an additional sling was attached to another screw fixed to the mesh 2-3 cm vertically above the first screw. Aesthetic results were confirmed immediately after surgery and later during outpatient follow-up. Both depression and lateral bulging were resolved, and there was no delayed drooping of the temporalis muscle on 6-month follow-up. There were no complications, and the patient was satisfied with the appearance. This is a simple yet effective technique with a low risk of complications, and should be considered for postoperative temporal hollowing patients, especially those with severe lateral bulging.

When human rights disputes are related to the cross-border investments treaties, the investment arbitral tribunals are confronted with the question of how to adjudicate connected human rights violations. The traditional structure restricts arbitration proceedings to the parties named within an investment treaty, i.e., Investor-Claimant and State-Respondent. If human rights issues occur, States must act as proxies for citizens with human rights claims. This effectively excludes individuals or groups with human rights concerns and contradicts the premise of international human rights law that seeks to empower human rights-holders to pursue claims directly and on an international stage. The methods for intorducing human rights issues in the context of investment arbitration proceedings are suggested as follows: First, human rights arguments can be introduced into ISDS by the usual initiator of investment disputes: the investor as the complainant. Especially, if the jurisdictional and applicable law clauses of the respective international investment agreements are sufficiently broad to include human rights violations, adjudicating a pure human rights claim could be possible. Second, the host state may rely on human rights argumentation as a respondent of an investor claim. Human rights have played a role as a justification for state measures undertaken to comply with human rights laws. Third, third party interventions by NGOs and civil society groups as amici curiae may act as advocates for affected populations or communities in response to the reluctance of governments to introduce their own human rights duties into the investment dispute. Finally, arbitrators have also referred to human rights ex officio, i.e., without having a dispute party referring to the specific argument. This was mainly the case in the context of determining the scope of property rights and the existence of an expropriation. As all U.N. member states have human rights obligations, international investment laws must be presumed to be in conformity with the relevant human rights obligations.

Recently, DC distribution systems have become a hot issue because of the increase in digital loads and DC generation systems according to the expansion of renewable energy technologies. To obtain the practical usage of DC electricity, safety should be guaranteed. The main concerns for safety are twofold: one side is human protection against electric shocks, and the other is facility protection from short faults. "Effects of current on human beings and livestock" (IEC 60479) defines a human body impedance model in electric shock conditions that consists of resistive components and capacitive components. Although the human body impedance model properly works in AC electricity, it does not well match with the electric shock behavior in DC electricity. In this study, the contradiction of the human body impedance model defined by IEC 60479 in case of DC electricity is shown through experiments for the human body. From the analysis of experimental results, a novel unified human body impedance model in electric shock conditions is proposed. This model consists of resistive components, capacitive components, and an inductance component. The proposed human impedance model matches well for AC and DC electricity environments in simulation and experiment.

Although human-sized bipedal humanoid robots have been developed as the ideal form of human-friendly robots, studies of humanoid robots from the user perspective and of actual interaction between humanoid robots and the public in daily environments are few. This paper presents a long-term public demonstration that encouraged interaction between a humanoid robot and unspecified individuals. We have collected a significant amount of subjective evaluation data from the public by performing a storytelling demonstration that enhanced people's empathy towards the robot. The evaluation model consists of the robot's human friendliness, which involves its impression on humans, interaction with humans, and imitation of human motions and the robot's human appearance which involves gender, age, height, and body type. This study shows that there is no significant difference in human-friendliness between gender groups (male and female), while there is a significant difference between age groups (children and adults). In human appearance, it appears that there is no significant difference between either gender groups or age groups, except for the case of the robot's height.

The main control room (MCR) in advanced nuclear power plants (NPPs) has changed from analog to digital control system (DCS). Operation and control have become more automated, centralized, and accurate due to the digitalization of NPPs, which has improved the efficiency and security of the system. New issues associated with human reliability inevitably arise due to the adoption of new accident procedures and digitalization of main control rooms in NPPs. The LingAo II NPP is the first digital NPP in China to apply the state-oriented procedure. In order to address issues related to human reliability analysis for DCS and DCS + state-oriented procedure, the Hunan Institute of Technology conducted a research project based on a cooperative agreement with the LingDong Nuclear Power Co. Ltd. This paper is a brief introduction to the project.

This study aims to identify the relationship between human resource management practices, work engagement, and proactive behavior of health workers in Gia Lai Province in Vietnam. Based on theoretical frameworks of human resource management, work engagement, and proactive behavior, this study developed a research model and tested its relationship between human resource management practices, work engagement, and the proactive behavior of healthcare workers in Gia Lai Province. This research has used a mixed research method with qualitative and quantitative research. The quantitative research was conducted by survey with 232 health workers. The hypotheses were tested by using structural equation modeling (SEM). The findings showed that human resource management practices have a positive and significant influence on proactive behavior, which directly influences healthcare workers' work engagement. Besides, work engagement plays a role in mediating the influence of human resource management practices on proactive behavior. This research implies that health care organizations should pay more attention to human resource management practices to improve work engagement that assists in increasing employee proactive behavior. Efficient human resource management practices help boost work engagement and, initiality, improve the quality of health care services and minimize errors in treatments.

High Electromagnetic Field (EMF) with an intensity of 1 mT (Tesla) inhibited the growth of both human normal lung and immune T cell down to $20-30\%$, compared to that of an unexposed case. The human T-cells, Jurkat, were more severely affected by EMF than the human lung cells, which showed a relatively slow cell growth and substantial releas of $Ca^+2$ (3.5 times higher than the human T-cells). However, the growth of hepatoma carcinoma, Hep3B, was enhanced by twice that of an unexposed case. The EMF intensity and exposure time did not affect the growth of the cancer cells very much, while it significantly affected the growth of normal cells. Accordingly, it is possible that EMFs may play a role in the initiation of cancer. The EMFs disturbed the signal transduction and membrane systems, such that a five times higher amount of PKC-${\alpha}$ was released from the cell membrane than in the control. Extended exposure to EMFs, for more than 48 hours, also led to 1 $90\%$ necrotic death pattern from apoptotic cell death. Finally, EMF at an intensity of 1mT with a 24-T exposure promoted the differentiation of HL-60 cells to monocytes/macrophages, possibly causing potential acute leukemia.
