This study aims to develop a detailed sizing system for lower body clothing for elderly obese women, using data from the 8th Korean Anthropometric Survey. The research targets 296 elderly women aged 60 to 85, selected from 805 participants in total, who meet the following criteria: Rohrer Index of 1.6 or above, Body Mass Index of 25 or higher, and Waist-Hip Ratio of 0.85 or greater. Elderly women with abdominal obesity exhibit shorter lower body proportions and greater fat accumulation in the torso, around the chest and waist. The findings show that women in their 60s have the highest level of obesity, while waist width and thickness are greatest in women in their 70s, suggesting that abdominal obesity increases with age. According to the KS standards, the main measurement categories were divided into 5cm increments for height, while waist and hip girth were categorized into 5cm and 3cm, respectively, to analyze the distribution of sections. Clothing size standards for lower garments that require a precise fit, such as skirts and formal pants, are presented in 13 sizes, corresponding to a waist girth range of 85–100cm and a hip girth range of 88–97cm. Detailed measurements are categorized into primary and reference areas. Additionally, sizes were presented differently based on whether a precise fit was necessary. For items that did not require a precise fit, ranges were indicated with letters, or ranges were indicated with measurements. Detailed sizes were categorized into primary and reference areas.
This study analyzes the discourse of Korean internet users regarding patient clothing and identifies the changes to structure and content of clothing resulting from infectious disease outbreaks. The analysis draws on texts from Korean blogs, internet cafes, and news articles from 2011 to 2021 related to patient clothing. Using Ucinet 5 and NodeXL 1.0.1 programs, network density, centrality, and cluster analyses were conducted using the Wakita–Tsurumi algorithm. Additionally, Latent Dirichlet Allocation (LDA) topic modeling was applied using Python 3.7 to further explore thematic patterns within the discourse. Throughout the period of study, it was found that users consistently discussed the specific purpose and functionality of patient clothing. Following the outbreak of COVID-19, the distribution and influence of keywords related to the functional aspects of patient clothing, such as “hygiene and safety,” significantly increased. An increased focus was placed on elements such as functionality, activity, autonomy, hygiene, and safety during the pandemic as public health concerns grew. It can be seen that patients increasingly share their experiences online and hospitalization rates surge during health crises; this study provides valuable insights into how the design of patient clothing can be improved through various informatics techniques. It underscores the evolving perception of patient clothing as essential medical equipment during health emergencies. In addition, it offers practical guidance for enhancing designs that better reflect shifting societal concerns, particularly regarding health, safety, and patient comfort.
The spent nuclear fuel, combusted and released in the nuclear power plant, is stored in the spent fuel pool (SFP) located in the fuel buildings interconnected with the reactors. In Korea, spent fuel has been stored exclusively in SFPs, prompting initiatives to expand storage capacity by either installing additional SFPs or replacing them with high-density spent fuel storage racks. The installation of these fuel racks necessitates obtaining a regulatory license contingent upon ensuring safe fuel handling and storage systems. Regulatory agencies mandate the formulation of various postulated accident scenarios and assessments covering criticality, shielding, thermal behavior, and structural integrity to ensure safe fuel handling and storage systems. This study describes an evaluation method for assessing the structural damage to storage racks resulting from fuel dropping as a part of the functional safety evaluation of these racks. A scenario was envisaged wherein fuel was dropped onto the base plates of the upper and lower sections of the storage racks, and the impact load was analyzed using the ABAQUS/Explicit program. The evaluation results revealed localized plastic deformation but affirmed the structural integrity and safety of the storage racks.
Ethylene-responsive factors (ERFs) are important plant transcription factors (TFs) that regulate plant responses against various abiotic stresses. However, little information of ERF genes involved in abiotic stress is available in petunia (Petunia ×hybrida). In this study, a petunia ERF gene, PhERF039, was cloned and functional analysis was performed. The quantitative PCR analysis revealed that PhERF039 was induced at the early stage of water deficit stress. Under-expression of PhERF039 (UE) exhibited rosette growth habit, higher number of branches, and delayed flowering compared to the wild type (WT). The UE petunia was evaluated under various volumetric water contents (θ): 0.25, 0.15, 0.10, or 0.05 m3·m-3 using an automated irrigation system. Transgenic plants did not delay plant wilting, but the θ for UE reached to the set point later than that for WT. A lower stomatal conductance was observed in UE than WT under all treatments. These results suggested that PhERF039 could be involved in plant responses under water deficit by regulating stomatal movements as well as branching pattern and flower development.

This study emphasizes the nonverbal strategies used by pre-service Earth science teachers, highlighting the importance of noverbal communication in teachers’ professional development and the need for its integration into education. It also establishes a systematic conceptual framework for understanding gestures in the instructional context.
Obesity occurs when the body consumes more energy than it requires and uses less energy, resulting in the accumulation of fat, which increases the number and size of fat cells in the body. It causes high blood pressure, type 2 diabetes, and joint crowding, making it difficult to fully treat. We investigated the effects of chito oligosaccharide(CHO) functional material, which suppresses fat accumulation, restores dyslipidemia values, and has no side effects.In this study, we investigated the ameliorative effects of CHO on obese mice fed a high-fat diet. The experimental groups were divided into 5 groups (n=10) of C57BL/6 mice: normal control (N), control group (C), and chito oligosaccharide low concentration (L), medium concentration (M), and high concentration (H) groups. We tested whether CHO has an effect on obesity through body weight and adipose tissue weighing, serum lipid testing, and histological examination. Experimental analysis showed that CHO reduced body weight and adipose tissue weight, improved the concentrations of TCHO, TG, HDL, and LDL, which are factors for dyslipidemia diagnosis, and decreased the diameter size of adipose tissue. These results suggest that CHO alleviates the levels of fat growth inhibition and dyslipidemia levels in obese-induced mice, and has a positive effect on obesity.
본 연구는 기능성 화장품 소재로서 생태교란종으로 지정되어있는 가시박 (Sicyos angulatus L., SA)의 이용 가능성을 알아보기 위하여 항산화, 미백, 항균, 항염증 효능 평가를 수행한 후, 에멀션 안정성을 확인하였다. SA는 초순수 (SAW)와 70% EtOH (SAE)로 추출하였다. SAE는 SAW와 비교하 여 DPPH radical 및 ABTS+ radical에 대한 소거 활성과 SOD 유사 활성이 보여 항산화의 효능이 뛰어 나며, tyrosinase의 활성을 저해하여 멜라닌 생성을 억제하였다. SAW는 Escherichia coli (E.c), Staphylococcus epidermidis (S.e), Staphylococcus aureus (S.a), Pseudomonas aeruginosa (P.a), Cutibacterium acnes (C.a) 균주에 대한 항균 효과가 없는 반면, SAE는 S.a를 제외한 E.c, S.e, P.a, C.a 균주에서 clear zone이 생성되어 항균 활성을 나타내었다. LPS를 처리한 RAW 264.7 세포에서 SAE는 SAW보다 iNOS 및 COX-2의 발현량이 억제됨으로써 NO의 생성량을 억제하여 항염증에 대한 효능을 나타내었다. SAE을 첨가한 에멀션을 4℃, 25℃, 50℃의 온도에서 분리 현상이 관찰되지 않고, pH와 점 도는 수치상 큰 변화가 없었으며, 입자크기가 대조군 에멀션의 입자와 유사하므로 제형에 영향을 끼치지 않음을 확인하였다. 본 연구 결과를 기반으로, 기능성 화장품 연구에 새로운 소재로서의 활용 가능성을 제시하고자 한다.

Tube, an intracellular protein of the Toll-pathway, forms a complex with Pelle and MyD88, and regulates a signal transduction to activate NF-κB in Drosophila. To understand the antimicrobial function of TmTube, the induction patterns of TmTube were investigated at 3, 6, 9, 12, and 24 h-post injection of pathogens into 10th to 12th instar larvae. In addition, we investigated the effects of TmTube RNAi on larval mortality and tissue specific AMP expression in response to microbial challenge. Our results will provide a basic information to elucidate the immunological function of TmTube
Lytic polysaccharide monooxygenases (LPMOs) catalyze the oxidative cleavage of glycosidic bonds in crystalline polysaccharides including chitin and cellulose. The recent discovery of LPMO family proteins in many insect species suggests that they presumably play a role in chitin degradation in the cuticle/exoskeleton, tracheae and peritrophic matrix during insect development. Insect LPMOs belong to auxiliary activity family 15 (AA15/LPMO15) and have been classified into at least four groups based on phylogenetic analysis. In this study, we identified and investigated the physiological functions of group I LPMO15 (MaLPMO15-1 and PhLPMO15-1) in two longhorn beetle species, Monochamus alternatus and Psacothea hilaris. In both species, depletion of LPMO15-1 transcripts by RNAi resulted in a lethal pupal-adult molting defect. The insects were unable to shed their old pupal cuticle and died entrapped in their exuviae. Furthermore, TEM analysis revealed a failure of degradation of the chitinous procuticle layer of their old cuticle, retaining intact horizontal laminae and vertical pore canals containing perpendicularly oriented chitin fibers (pore canal fiber, PCF) in their core. These results indicate that MaLPMO15-1 and PhLPMO15-1 are required for turnover of the chitinous old cuticle, which is critical for insect molting.
The genus Argiope are known to decorate their webs with various patterns. The purpose of these web decorations, referred to as stabilimenta, is still a subject of debate. They are believed to serve either as lures to attract prey insects or as a means of providing protection to the spider by enhancing the web's visibility to deter potential predators. In this study, we observed spider orientation with respect to the direction of the sun in a controlled laboratory environment. To assess the orientation preference of the spider, the frame was repositioned daily by reversing its direction. Over a period of 21 days, the orientation of the spider was meticulously recorded, distinguishing between the illuminated side (open side) and the shaded side (closed side). field emission scanning electron microscopy (FESEM) visualization were used to investigate the microstructural characterization of stabilimenta in both juvenile and adult spiders. Our results represent that the decorative structure of stabilimentum shows diverse microstructural features according to the maturation level of the spider. In addition, it has been confirmed that spiders tend to prefer the open side direction when stabilimentum is present.

최근 해사산업 분야에서는 4차 산업혁명의 대명사로서 자율운항선박 관련 자율운항기술 및 원격운항기술 등의 개발이 활발히 진행되어 자율운항선박에 대한 본격적인 실증이 현실화되고 있다. 이러한 자율운항선박이 현실화가 된다 면 이러한 선박이 국제해사협약 체계 내에서 아무 문제없이 운항이 가능해야 할 것이며, 이를 위한 정책적, 법제적 준비가 제대로 이루어져야 할 것이다. 이 를 위해 자율운항선박이 운용되기 위하여 반드시 고려되어야 하는 인적요인의 역할 변화에 대한 법제적 및 기능적 검토가 필요하다. 먼저 국제협약 및 국내법에서는 인적요인에 대한 여러 규정을 두고 있으며 선박의 해상에서의 안전을 확보하기 위하여 자격 있는 선원의 승선 및 통제를 전제로 하여 선박과 인적요인을 분리하고 있지 않다. 다만, 자율운항선박의 경 우 기국이 재량에 따라 판단하여 선원이 승선하지 않아도 안전하고 효율적으로 선박을 운항할 수 있다고 판단한다면 반드시 선원의 승선이 필요한 것은 아니 라고 볼 것이다. 특히, 선박의 안전운항을 위하여 그동안 선장 및 해기사가 수 행해 온 역할들이 누락없이 축소된 최소 선원, 원격운항자 및/또는 첨단기술로 적절히 이전된다면 그러한 시대변화를 뒷받침할 수 있을 것으로 보인다. 따라서 이 논문에서는 IMO에서 논의가 되고 있는 원격운항자의 역할과 책임 과 관련하여 기존 해기사의 기능 중 원격운항자가 이어 받아 수행할 수 있는 기능을 식별하고 그러한 기능에서 요구되는 해기능력을 확인하여 제시하고자 하였으며, 향후 원격운항자의 요구능력으로 참조할 수 있을 것이다.
