In this study, 2,238 incidents from History of the Three States, Prehistory of the Three States, History of Koryo, True Records of Chosun Dynasty had been analyzed in order to examine the bathing styles of Koreans. The results were as follows. In the period of Three States, baths were taken for the purposes of cleanness, remedy, and beauty culture as well as etiquettes. And spa, rainwater, rivers, streams, and bath tubs were used. In the period of Koryo, it included not only reasons for etiquettes as in the period of the Three States but also reasons for medical care and daily life. In spa, temples, and homes, baths were taken by using perfumes and towels. In Chosun Dynasty, daily baths were for hygiene, health, and bodily charms. Before religious ceremonies, they made sure that they took baths, and spa baths were popular for the medical care. The ways to take baths included the order which area was the first to be washed, time, and areas concretely, and seasons, weather, and conditions of body were considered before taking baths. Moreover, the places included natural places such as streams, reservoirs, rivers, as well as artificial places such as temples, places for envoys, and palaces. Especially, in spa areas, bathing buildings were constructed. Considering all these, baths were taken for the purposes of ceremonies and medical care in the period of the Three States, and daily baths took down their roots in the period of Koryo. In the period of Chosun Dynasty, spa baths for cures, prays and rituals, hygiene and bodily charms were considered as a reason. How to take baths and means were decided carefully. Therefore, the results above demonstrated that baths took down their roots in people's daily life in Korea since the period of Koryo.

Pulsatile Extracorporeal Membrane Oxygenation(ECMO) can mitigate the heart load and raise the patient's blood perfusion. But If the ECMO pulsate the blood flow during the systolic period, It can burden to the patient's heart. To avoid the heart injury, we have to consider the relation between output of ECMO, hemodynamic states and heart movement. To raise the efficacy of the pulsatile ECMO, we investigated the coronary perfusion, cardiac muscle tension and hemodynamic states during the ECMO perfusion by using the mathematical model of human blood circulatory system and ECMO. The outflow data of the pulsatile ECMO(T-PLS, Bioheartkorea, Korea) was obtained in vitro experiments. According to the phase and pumping rate of the ECMO, the heart's load and coronary perfusion could be adjusted to the proper levels. The results of the human- ECMO lumped parameter model showed that the synchronizing operation of the pulsatile ECLS can be helpful at stabilizing the patient's hemodynamic states.

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.

This paper presents a study on the fuzzy based approach for the safety assessment of human body under ELF electric and magnetic(EM) field considering power system states. The analysis of ELF EM field based on quasi-static method is introduced. UP to the present, the analysis of ELF EM field has been conducted with the consideration of one transmission line, or a power line model only In this paper, however, the power system is included to model the expected and/or unexpected uncertainty caused by the load fluctuation and parameter changes and the states are classified into two types, normal state resulting from normal operation and emergency state from outages. In order to analyze the uncertainty in the normal state, the Monte Carlo Simulation, a statistic approach was introduced and line current and bus voltage distribution are calculated by a contingency analysis method, in the emergency state. To access the safety of human body, the approach based on fuzzy linguistic variable is adopted to overcome the shortcomings of the assessment by a crisp set concept. In order to validate the usefulness of the approach suggested herein, the case study using a sample system with 765(kV) was done. The results are presented and discussed.

This paper describes user context awareness system, which is one of the most essential technologies in various application services of ubiquitous computing. The proposed system used two-axial accelerometer, embedded in $SenseWear^{(R)}$ PRO2 Armband (BodyMedia). It was worn on the right upper arm of the experiment subjects. Using this data, PC-based fuzzy inference system was realized to distinguish human motion states, such as, tying, sitting, walking and running. The recognition rates of human motion states were 100 %, 98.64 %, 99.27 % and 100 % respectively for tying, sitting, walking and running.

In abnormal states of nuclear power plants (NPPs), operators undertake mitigation actions to restore a normal state and prevent reactor trips. However, in abnormal states, the NPP condition fluctuates rapidly, which can lead to human error. If human error occurs, the condition of an NPP can deteriorate, leading to reactor trips. Sudden shutdowns, such as reactor trips, can result in the failure of numerous NPP facilities and economic losses. This study develops a remaining trip time (RTT) prediction system as part of an operator support system to reduce possible human errors and improve the safety of NPPs. The RTT prediction system consists of an algorithm that utilizes artificial intelligence (AI) and explainable AI (XAI) methods, such as autoencoders, light gradient-boosting machines, and Shapley additive explanations. AI methods provide diagnostic information about the abnormal states that occur and predict the remaining time until a reactor trip occurs. The XAI method improves the reliability of AI by providing a rationale for RTT prediction results and information on the main variables of the status of NPPs. The RTT prediction system includes an interface that can effectively provide the results of the system.

In the United States (US), due to the Common Rule, completely revised in 2017, single Institutional Review Board (IRB) review has become mandatory for government-sponsored multi-institutional research since 2020 regardless of the number of participating institutions. The goal of these changes is to reduce redundant reviews by the IRB at each institution and better protect research participants. In this paper, single IRB and Human Research Protection Program (HRPP) in the US and Korea were compared and considered, and their implications were discussed. A comparison of the HRPP evaluation and certification systems of the US and Korea includes that of SMART IRB in the US and Korea Central IRB, aiming at single IRB review for efficient review with support from the country and building a more efficient national human subject research network in the future. Its comparison and analysis will be helpful in deriving future tasks and development directions of single IRB and HRPP in Korea.

The human oral cavity contains a highly personalized microbiome essential to maintaining health, but capable of causing oral and systemic diseases. Thus, an in-depth definition of "healthy oral microbiome" is critical to understanding variations in disease states from preclinical conditions, and disease onset through progressive states of disease. With rapid advances in DNA sequencing and analytical technologies, population-based studies have documented the range and diversity of both taxonomic compositions and functional potentials observed in the oral microbiome in healthy individuals. Besides factors specific to the host, such as age and race/ethnicity, environmental factors also appear to contribute to the variability of the healthy oral microbiome. Here, we review bioinformatic techniques for metagenomic datasets, including their strengths and limitations. In addition, we summarize the interpersonal and intrapersonal diversity of the oral microbiome, taking into consideration the recent large-scale and longitudinal studies, including the Human Microbiome Project.

This study investigated how family capital was associated with the working memory of young school-aged children from immigrant families in the United States using the New Immigrant Survey. Family capital was identified as economic, human, cultural, and social capital, and children's working memory was measured by the Digit Span scores. Poisson regression analysis was used for examining the sample of 428 children from the New Immigrant Survey. Results indicated that cultural capital within the home was positively associated with the working memory of young school-aged children whereas economic, human, and social capital was not. Implications and limitations of the study are also discussed.

The emotion recognition is one of the most significant interface technologies which make the high level of human-machine communication possible. The central nervous system stimulated by emotional stimuli affects the autonomous nervous system like a heart, blood vessel, endocrine organs, and so on. Therefore bio-signals like HRV, ECG and EEG can reflect one' emotional state. This study investigates the correlation between emotional states and bio-signals to realize the emotion recognition. This study also covers classification of human emotional states, selection of the effective bio-signal and signal processing. The experimental results presented in this paper show possibility of the emotion recognition.
