An ongoing research project is devoted to the design and implementation of a satellite based asset tracking for supporting emergency management in crisis operations. Due to the emergency environment, one has to rely on a low power consumption wireless communication. Therefore, the communication hardware and software must be designed to match requirements, which can only be foreseen at the level of more or less likely scenarios. The latter aspect suggests a deep use of a simulator (instead of a real network of sensors) to cover extreme situations. The former power consumption remark suggests the use of a minimal computer (Raspberry Pi) as data collector.

The objective of this field research is to determine consumer's fashion sense and provide helpful information to manufacturers when planning designs and merchandizing strategies. This study's purpose was to observe what was being worn, colors and tones. The method of research was fixed point observation using digital photos. The subjects of the research were female college students, 18-22 years old. The T-shirt has become the representative item for casual and comfortable wear by the female college students. Pants and blue jeans were worn more often than skirts as a lower garment. This shows that the students think about their activities when choosing a lower garment. The majority of these students chose clothing that functioned well for their school activities. Among students that wore skirts about half wore a functional knee length while the other half wore a more fashionable mini-skirt. These students appear to care about both fashion and function. Blue was especially popular, with 70.4% of all lower garments being blue. This effect makes the body look thinner and may be one reason why blue is so popular. White is a popular color as an upper garment. White upper garments are easily matched with any color, while blue upper garments coordinate well with similarly colored blue lower garments. The distribution of upper garment color is significantly influenced by the seasons. Blue jean tones were many and varied, while upper garments were mostly weak tones and bright tones of pale, light and soft.

Purpose: The current study focused on developing Klong Kone Shrimp Paste (Mesopodopsis) products and packaging, aiming to enhance the capabilities of entrepreneurs with cultural capital in post-pandemic Samut Songkhram Province. Research design, data and methodology: This study sought to analyze product and packaging issues and examine packaging expectations for Klong Kone shrimp paste. A combination of quantitative and qualitative methods was used, including a questionnaire administered to a sample of 400 individuals who purchased community enterprise products. Descriptive analysis, involving percentage, mean, and S.D., along with qualitative analysis through phenomenological methods, such as in-depth interviews and focus groups, were conducted with community enterprise entrepreneurs, experts, and customers. Results: The findings indicate that addressing product conditions and packaging issues with Klong Kone shrimp paste can be achieved by incorporating an attached label on the community product packaging. Conclusion: This approach is necessary due to the lack of community identity reflection and unattractive design, which currently deter customers from considering the products as souvenirs. Additionally, diversifying product offerings is recommended to better align with consumer needs. In terms of packaging expectations, a majority of respondents expressed a strong preference for an attractive appearance.

Purpose: The purpose of this study was to test a model of nursing competencies of nursing simulation learners. The conceptual model was based on the theory of Jeffries's simulaton theory. Methods: Data collection was conducted in October 2017 for 310 students from two nursing universities in Kyungbuk area for 20 days. Data analysis methods were covariance structure analysis using SPSS 21.0 and AMOS 22.0 statistical programs. Results: The hypothetical model was a good fit for the data. The model fit indices were comparative fit index=.97, normed fit index=.94, Tucker-Lewis Index=.97, root mean square error of approximation=.44, and standardized root mean square residual=.04. Teacher factors were directly related to simulation design characteristics, and it was confirmed that the curriculum, classroom operation and teaching method of the instructors were important factors. Learner factors were found to have a direct effect on nursing competence, self-confidence, and clinical performance that belong to nursing capacity. In particular, the results of this study indicate that the simulation design characteristics have a partial mediating effect on learner factors and clinical performance, and a complete mediating effect on learner factors and clinical judgment ability. Conclusion: In order to improve the learner's clinical performance and clinical judgment ability, it is necessary to conduct practical training through nursing simulation besides preparing the learner and the educator.

Hydraulic coupling systems play an important role in easily connecting or disconnecting pipes or hoses that transmit high-pressure fluids without hydraulic oil leakage in hydraulic power transmission equipment. A flat-face hydraulic quick coupler is a recently developed product that can reduce environmental pollution by minimizing hydraulic oil leakage during connection and disconnection. In this study, the influence of the shape of the inner ring of a 3/8" flat-face hydraulic quick coupler on its internal flow characteristics was analyzed and evaluated by numerical analysis based on computational fluid dynamics. The flow velocity distribution, temperature distribution, and optimal shape design of the inner ring were obtained by comparing the results of the flow characteristics, such as the pressure drop.

Objective: The aim of this study was to investigate the inter-rater and intra-rater reliability of rehabilitative ultrasound imaging (RUSI) for measurement of muscle thickness with changes in angles of the gluteus maximus (GM) at rest and during contraction. Design: Cross-sectional study. Methods: Twenty-two healthy men volunteered for this study. GM muscle images were obtained in the resting position and during prone hip extension with knee flexion at hip abduction angles of $0^{\circ}$ and $30^{\circ}$, respectively. Two examiners randomly measured the thickness of the GM twice in three different positions. The first position was a comfortable prone position. The second position was prone hip extension with knee flexion (PHEKF) to $90^{\circ}$. The third position was achieved by hanging a 1-kg weight on the ankle of the lifted leg during PHEKF with the angle of the lifted leg the same as the second position. Intra-class correlation coefficients (ICCs), standard error measurements, and minimal detectable changes were used to estimate reliability. Results: The intra-rater reliability ICCs (95% confidence interval) of the GM were >0.870, indicating good reliability. Inter-rater reliability ICCs ranged from 0.668 to 0.913. The reliability of measurements of muscle thickness at each position was similar to the reliability of the angle change. Differences in muscle thickness and ratios for each position with $0^{\circ}$ and $30^{\circ}$ of hip abduction were not statistically significant. Conclusions: In the present study, the intra-rater reliability of muscle thickness measurements of the GM was good, and the inter-rater reliability was moderate to good. Reliable RUSI measurements of wide and large muscles, such as the GM muscle at rest and during contraction, are feasible. Further investigation is required to establish the reproducibility of the protocols presented in this study.
