This paper examines how noblewomen during the Joseon Dynasty perceived incense and herbs, focusing on the 『Gyuhap Chongseo(閨閤叢書)』 a compendium edited by Yi Bingheogak(李憑虛閣, 1759~1824). The 『Gyuhap Chongseo』 is a classified collection of knowledge deemed essential for managing a noble household. By analyzing the content related to incense and herbs focused on 「Bongim Cheok」. This study reveals Yi Bingheogak's practical and realistic understanding of incense and herbs. For Yi, incense and herbs transcended mere cosmetic applications and luxury and served as indispensable tools in health and hygiene and domestic skills for traditional household management. While it may be challenging to generalize the perception of noblewomen solely based on the 『Gyuhap Chongseo』 the consistent transcription and transmission of the text suggest it resonated with the noblewomen's sentiments. With limited records left by noblewomen themselves, this study primarily explores Yi Bingheogak's perspective, who provided detailed knowledge and applications of incense and herbs across the compendium's sections. This reflects Yi's intention to broaden women's knowledge and cultural literacy, and contribute to improved quality of life through practical knowledge. This study demonstrates Yi's recognition of incense and herbs as vital commodities for the operation of domestic life, and illustrates how noblewomen of the Joseon Dynasty actively contributed to society and the household through knowledge and practical activities. The use of incense and herbs for beauty and domestic knowledge in various fields of traditional knowledge underscores a comprehensive understanding of noblewomen's perception and use of incense and herbs during the Joseon Dynasty.

Sedation can resolve anxiety and fear in patients undergoing endoscopy. The use of sedatives has increased in Korea. Appropriate sedation is a state in which the patient feels subjectively comfortable while maintaining the airway reflex for stable spontaneous breathing. The patient should maintain a state of consciousness to the extent that he or she can cooperate with the needs of the medical staff. Despite its benefits, endoscopic sedation has been associated with cardiopulmonary complications. Cardiopulmonary complications are usually temporary. Most patients recover without sequelae. However, they may progress to serious complications, such as cardiovascular collapse. Therefore, it is essential to screen high-risk patients before sedation and reduce complications by meticulous monitoring. Additionally, physicians should be familiar with the management of emergencies. The first Korean clinical practice guideline for endoscopic sedation was developed based on previous worldwide guidelines for endoscopic sedation using an adaptation process. The guideline consists of nine recommendations based on a critical review of currently available data and expert consensus when the guideline was drafted. These guidelines should provide clinicians, nurses, medical school students, and policy makers with information on how to perform endoscopic sedation with minimal risk.

This study is about the fabrication of a flexible electrode based on PAN-based carbon fibers tow using organic/inorganic nanocomposite and its application of non-enzymatic sensor. The organic/inorganic nanocomposite was composed of the conductive polymer polyaniline (PANI) and the metal oxide CuO. And glucose was used as the target of the electrochemical sensor. Commercialized CFTs were pretreated through heat treatment for desizing and electrochemical oxidation for activation. This nanocomposite was sequentially synthesized on the pretreated CFT surface using electrochemical polymerization and electrochemical deposition. Finally, the CFT/PANI/CuO NPs electrode was obtained. The electrochemical properties and sensing performance of the CFT/PANI/CuO NPs electrode were analyzed using chronoamperometry (CA), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). The sensitivity of the CFT/PANI/CuO NPs electrode was about 8.352 mA/mM (in a linear range of 0.445~6.674 mM) and 3.369 mA/mM (in a linear range of 6.674~50 mM), respectively. So, the CFT/PANI/CuO NPs electrode exhibited the enhanced sensing performances due to unique properties such as small peak potential separation, low electron transfer resistance, and large specific surface area.

The lactate electrode can be utilized either as an electrode for lactate sensor to monitor the patient's health status, stress level, and athlete's fatigue in real time or lactate fuel cell. In this study, we fabricated a high-performance electrode composed of lactate oxidase, catalase, and mitochondria, and investigated the surface analysis and electrochemical properties of this electrode. Carbon paper modified with single-walled carbon nanotubes (CP-SWCNT) had significantly improved electrical conductivity compared to before modification. The electrode to which lactate oxidase, catalase, and mitochondria were attached (CP-SWCNT-LOx-Cat-Mito) produced a higher current than the electrode to which lactate oxidase and catalase were attached. The amount of reduction current produced by the bilirubin oxidase (BOD)-attached electrode (CP-SWCNT-BOD) was greatly affected by the presence or absence of oxygen in the electrolyte. The fuel cell composed of CP-SWCNT-LOx-Cat-Mito (anode) and CP-SWCNT-BOD (cathode) produced maximum power (29 ㎼/cm²) at a discharge current density of 133 ㎂/cm². From this study, we had proved that mitochondria is essential for improving lactate sensor and fuel cell performance.

A hiking stick is generally one of the walking aids that allow hikers to walk while relying on their own bodies when walking. A rechargeable battery must be built into the hiking stick, which is an auxiliary device, in order to perform various functions. A separate power supply is required to charge the rechargeable battery. This study is about a self-generated power supply and develops a power generation device using a screw with higher power generation efficiency than the existing method. It is differentiated from the method suggested in this study by comparing and analyzing it with the existing power generation method, and identifying problems therewith. The screw-type power generation device generates power when the climbing stick comes into contact with the ground and when it is separated from the ground. The built-in power generation device does not require a separate power supply, and it can be used by attaching the role of a mobile phone auxiliary battery and a lighting lamp, and it has the effect of being able to find it through location tracking by embedding a GPS sensor, etc., and using lighting to keep the user safe in emergency situations such as distress. The existing generator with built-in mountain climbing stick is difficult to charge due to very weak current and low practicality, but the generator developed in this research could achieve high efficiency to obtain a sufficient current, so it is possible to charge a battery and practicality.

This study was conducted to determine the status of allergic diseases and mental health in adolescents, confirm the relationship between allergic diseases and mental health, and provide basic data for developing effective disease management measures for adolescents at the developmental stage. Secondary analysis was performed on the data from the 17^th Youth Health Behavior Online Survey, and complex sample descriptive statistics, cross-tabulation, and logistic regression analysis were performed using the SPSS 26.0 program. As a result of the study, those with one or more allergic diseases were 1.286 times more likely to have stress (B=1.286, p<.000), 1.289 times more likely to be depressed (B=1.289, p<.000), and 1.399 times more likely to have generalized anxiety disorder (B=1.399, p<.000) was highly likely to experience it. Additionally, factors affecting the mental health of adolescents with allergic diseases were gender, economic level, academic performance, drinking experience, and smoking experience. Stress and generalized anxiety disorder were more likely to be experienced by female students, if they had a lower economic level and academic performance, and if they drank alcohol or smoked. Male students were more likely to experience depression if their economic level and academic performance were higher, and if they did not drink alcohol or smoke. Based on these results, we hope to establish a practical approach by establishing effective strategies to manage allergic diseases in adolescents and the mental health conditions that may arise from them.

The purpose of this study is a descriptive research study to identify middle-aged women's positive thinking, perceived health status, aging anxiety, and meaning of life, identify relationships between variables, and analyze predictive factors affecting the meaning of life. This study was approved by IRB (1040117-202208-HR-024-01), from September 10, 2022 to February 28, 2023, data were collected from 130 middle-aged women. The data was analyzed using SPSS WIN 26.0 version. Positive thinking and perceived health status(r=.43, p<.001), positive thinking and meaning of life(r=.54, p<.001), perceived health state and meaning of life(r=.31, p<.001) showed a statistically significant positive correlation. Positive thinking and aging anxiety(r=-.20, p=.021) and perceived health state and aging anxiety(r=-.46, p<.001) showed a statistically significant negative correlation. Aging anxiety and meaning of life(r=-.10, p=.281) were not statistically significant. Factors influencing the meaning of life among middle-aged women were found to be positive thinking (𝛽=.52, p<.001), menopausal status (𝛽=-.22, p=.003), with meaning of life (F=32.49, p<.001) explaining 32.8%. As the positive thinking of middle-aged women has been identified as a predictor of the meaning of life, it is considered necessary to develop an intervention program to promote positive thinking of middle-aged women.
