Purpose: The study aimed to clarify the concept of spiritual self-care in hospice team members. Methods: To analyze the concept of spiritual self-care of hospice care team, the study was carried out using Schwartz-Barcott and Kim's hybrid model including theoretical, fieldwork and final analytic stages. In the theoretical stage, 'spirituality', 'spiritual well-being', 'spiritual health', 'spiritual care', and 'self-care' were set as search terms, and the resulting 107 related works of domestic and international literature were analyzed. In the field survey stage, data were collected from nurses and spiritual experts with more than 5 years of experience in spiritual self-care. Results: The concept of spiritual self-care is to realize the meaning and purpose of life while constantly maintaining relationships with oneself, neighbors, communities, and the absolute, utilize transcendence and internal resources, strengthen professional competence, maintain work-life balance, and achieve spiritual well-being. It was identified as a dynamic state to realize. The quality attributes of the concept of spiritual self-care were found to have 5 attributes and 15 indicators. Conclusion: The attributes and indicators derived through this study will be helpful in understanding the concept of hospice team members' spiritual self-care. In addition, as a way to continuously grow and train professional hospice team members, it can be used to develop a spiritual self-care assessment tool and an educational program to prevent burnout.

This paper describes a method of building Korean conversational speech data in the emergency medical domain and proposes an annotation method for the collected data in order to improve speech recognition performance. To suggest future research directions, baseline speech recognition experiments were conducted by using partial data that were collected and annotated. All voices were recorded at 16-bit resolution at 16 kHz sampling rate. A total of 166 conversations were collected, amounting to 8 hours and 35 minutes. Various information was manually transcribed such as orthography, pronunciation, dialect, noise, and medical information using Praat. Baseline speech recognition experiments were used to depict problems related to speech recognition in the emergency medical domain. The Korean conversational speech data presented in this paper are first-stage data in the emergency medical domain and are expected to be used as training data for developing conversational systems for emergency medical applications.

<P><B>Abstract</B></P> <P>Lytic induction of latent Epstein-Barr virus (EBV) has been considered as a therapeutic approach for efficient treatment of EBV-associated malignancies.

Expression of lytic genes were efficiently induced by each <I>Euphorbia</I> extract in SNU-719 (EBV-positive gastric carcinoma cells). <I>Euphorbia pekinensis</I>, out of three extracts, exhibited the most potent lytic-inducing activity. Importantly, treatment with <I>E. pekinensis</I> extract led to an obvious cytotoxic effect on SNU-719 cells, but little on MKN-74 cells (EBV-negative gastric carcinoma cells), indicating the selective oncolytic effect on EBV-positive gastric carcinoma. We further revealed that lytic-inducing activity of <I>E. pekinensis</I> was mediated by PKC/MEK signal. Moreover, we defined two structural analogs of PMA with strong lytic-inducing activity, suggesting their therapeutic applicability for the treatment of EBV-associated gastric carcinoma.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Identification of three <I>Euphorbia</I> extracts with EBV lytic-inducing activity. </LI> <LI> <I>Euphorbia</I> extracts efficiently induce lytic replication in most of cell population. </LI> <LI> <I>Euphorbia</I> extracts induce EBV reactivation through modulating PKC/MEK pathway. </LI> <LI> PMA analogs in <I>Euphorbia</I> extracts contribute to lytic induction of EBV. </LI> <LI> <I>E. pekinensis</I> extract has an oncolytic effect selectively on EBV-positive gastric carcinoma cells. </LI> </UL> </P>

The anti-inflammatory effects of an ethanol extract of Angelica gigas (EAG) were investigated in vitro and in vivo using croton oil-induced inflammation models. Croton oil (20 μg/mL) up-regulated mRNA expression of cyclooxygenase (COX)-I and COX-II in the macrophage cell line, RAW 264.7, resulting in the release of high concentrations of prostaglandin E2 (PGE2). EAG (1∼10 μg/mL) markedly suppressed croton oil-induced COX-II mRNA expression and PGE2 production. Application of croton oil (5% in acetone) to mouse ears caused severe local erythema, edema and vascular leakage, which were significantly attenuated by oral pre-treatment with EAG (50∼500 mg/kg). Croton oil dramatically increased blood levels of interleukin (IL)-6 and PGE2 without affecting tumor-necrosis factor (TNF)-α and nitric oxide (NO) levels. EAG pre-treatment remarkably lowered IL-6 and PGE2, but did not alter TNF-α or NO concentrations. These results indicate that EAG attenuates inflammatory responses in part by blocking the COX - PGE2 pathway. Therefore, EAG could be a promising candidate for the treatment of inflammatory diseases.
Realistic Circuit Model of an Impact-Based Piezoelectric Energy Harvester
Kim, Sunhee,Ju, Suna,Ji, Chang-Hyeon,Lee, Seungjun The Institute of Electronics and Information Engin 2015 Journal of semiconductor technology and science Vol.15 No.5
A vibration-based energy harvester and its equivalent circuit models have been reported. Most models predict voltage signals at harmonic excitation. However, vibrations in a natural environment are unpredictable in frequency and amplitude. In this paper, we propose a realistic equivalent circuit model of a frequency-up-converting impact-based piezoelectric energy harvester. It can describe the behavior of the harvester in a real environment where the frequency and the amplitude of the excitation vary arbitrarily. The simulation results of the model were compared with experimental data and showed good agreement. The proposed model can predict both the impact response and long term response in a non-harmonic excitation. The model is also very useful to analyze the performance of energy conversion circuitry with the harvester.
Improved Metal Object Detection Circuits for Wireless Charging System of Electric Vehicles
( Sunhee Kim ) 한국인터넷정보학회 2023 KSII Transactions on Internet and Information Syst Vol.17 No.8
As the supply of electric vehicles increases, research on wireless charging methods for convenience has been increasing. Because the electric vehicle wireless transmission device is installed on the ground and the electric vehicle battery is installed on the floor of the vehicle, the transmission and reception antennas are approximately 15-30 cm away, and thus strong magnetic fields are exposed during wireless charging. When a metallic foreign object is placed in the magnetic field area, an eddy current is induced to the metallic foreign object, and heat is generated, creating danger of fire and burns. Therefore, this study proposes a method to detect metallic foreign objects in the magnetic field area of a wireless electric vehicle charging system. An active detection-only coil array was used, and an LC resonance circuit was constructed for the frequency of the supply power signal. When a metallic foreign object is inserted into the charging zone, the characteristics of the resonance circuit are broken, and the magnitude and phase of the voltage signal at both ends of the capacitor are changed. It was confirmed that the proposed method has about 1.5 times more change than the method of comparing the voltage magnitude at one node.
