Purpose: The purpose of this study was to investigate the degree and pattern of knowledge management process, and to identify the relationship between knowledge management process and organizational effectiveness in clinical nurses. Method: Participants were 665 regular clinical nurses who had worked for over 1 year in general units of 9 tertiary medical hospitals including 2 national university hospitals, 5 university hospitals, and 2 hospitals founded by business enterprises. Data were collected from March to May 2003 through questionnaires. Four structured instruments were used to collect the data: Knowledge Management Process Scale(Jeong, Lee, Lee, & Kim, 2003), cCommitment Questionnaire(Mowday, Steers, & Porter, 1979), General Satisfaction Scale(CooK, Hepworth, Wall, & Warr, 1981), and one for general characteristics. The data were analyzed using factor analysis, reliability analysis, descriptive analysis, cluster analysis, one-way ANOVA, Scheffe test, correlation analysis with the SPSS for Windows 10.0 program. Result: 1) The average score for knowledge management process in nurses was $3.08{\pm}.54$ on a 5-point Likert scale. In order from highest mean score, the elements of knowledge management process, were Knowledge $Utilization(3.35{\pm}.57)$, Knowledge $Sharing(3.07{\pm}.58)$, Knowledge $Creation(2.99{\pm}.63)$, and Knowledge $Storage(2.91{\pm}.82)$. 2) Four knowledge management patterns for nurses, which were derived from cluster analysis, were inactivate pattern, delayed pattern, activate pattern, and high-activate pattern of knowledge management. 3) The degree of knowledge management process activation and 4 elements of knowledge management process, Knowledge Creation, Knowledge Storage, Knowledge Sharing, and Knowledge Utilization, were significantly correlated with nurses' organizational commitment and job satisfaction(p=.000). 4) The nurses' organizational commitment and job satisfaction showed significant differences according to the knowledge management patterns derived from cluster analysis of high-activate pattern, activate pattern, delayed pattern, inactivate pattern(p=.000). Conclusion: These results suggest that there are four knowledge management patterns for nurses, and knowledge management process positively affects the nurses' organizational commitment and job satisfaction. From the above findings, knowledge management process is empirically verified as a useful and effective method to increase organizational effectiveness, and develop the organization.

For stable silkworm breeding and high-quality sericulture product production, the detection of Pebrine disease in silkworm eggs is critical. Current diagnostic methods can be timeconsuming and complex. This study aimed to develop a simplified and rapid diagnostic method using loop-mediated isothermal amplification (LAMP) technology to detect pebrine infection in silkworm mother moths. Eight primer candidates targeting the ribosomal gene region of microsporidia were designed and evaluated for specificity and detection sensitivity. A simplified nucleic acid extraction method was established, and isothermal amplification was performed using the selected primers. Of these, primers ID30 and ID45 showed no polymerization, while ID5, ID18, and ID76 exhibited nonspecific reactions, making them unsuitable. Primers ID1, ID6, ID45, and ID82 successfully amplified DNA only in the presence of pebrine, with ID82 demonstrating the best reproducibility and sensitivity, detecting as low as 2.5 pg/ul of DNA through electrophoresis and 5 pg/ul via a colorimetric change with phenol red. The entire process, from nucleic acid extraction to detection, was completed within 60 min. The use of the ID82 primer set in LAMP technology offers a promising and efficient approach for the rapid diagnosis of pebrine disease, potentially enhancing quality control in sericulture.

Background: Hanwoo cattle farmers aim to improve calf production and reproductive efficiency. Recovery of the reproductive tract postpartum is a critical factor influencing the postpartum period and conception of breeding cows. This study aimed to precisely analyze the recovery process of the reproductive tract in primiparous Hanwoo postpartum and to establish recovery criteria. Methods: Ten primiparous Hanwoo cows were used in this study. After parturition, estrus was examined daily using visual observations and estrus detection patches. Ovarian recovery, cervical diameter, and uterine horn diameter were examined using ultrasonography four times per week. Results: The analysis revealed that the first estrus occurred at 19.1 ± 6.5 days postpartum, the first ovulation at 27.1 ± 4.5 days, and the first normal estrus cycle at 39.2 ± 6.4 days. The ovulation rate during the first estrus was 40%. A normal estrus cycle occurred in 11.1% of patients at the first ovulation. The cervix diameter recovered to 42.0 ± 3.5 mm and the uterine horn diameter to 34.4 ± 7.1 mm by 24 days postpartum, with the difference in uterine horn diameter recovering to 2.6 ± 1.2 mm by 31 days postpartum. Conclusions: This study can aid in determining the optimal breeding time for postpartum primiparous Hanwoo cow and provide foundational data for Hanwoo breeding studies.

The wound healing process can be categorized as follows : inflammation, fibroplasia, neovascularization, collagen deposition, epithelialization, and wound contraction. During the healing process, various growth factors are secreted to accelerate wound healing. Previous studies have demonstrated that endogenous growth factors, such as vascular endothelial growth factor(VEGF) are the important regulatory polypeptides for coordinating the healing process. They are released from macrophages, fibroblasts, and keratinocytes at the site of injury and participate in the regulation of reepithelization, granulation tissue formation, collagen synthesis and neovascularization. Onchung-Um has been used clinically to treat various skin diseases. In addition, Onchung-Um has been also used for congestive inflammations. In the present study, we evaluated the effects of Onchung-Um on wound healing process and wound size reduction in rats. Full-thickness skin wounds ($15mm\;{\times}\;15mm$) were created on the back of rats. Rats were then divided into 2 groups : The Onchung-Um treated group that was orally administered with a dose of 193.9mg/100g of Onchung-Um extract per day for 15 days and Control group without Onchung-Um administration. Moreover, the histological changes and VEGF immunoexpressions of two groups were estimated. In results, wound closures were significantly accelerated by oral administration of Onchung-Um extract. Furthermore, in Onchung-Um treated group, there were significant increases in fibroblast migration, epithelialization compared with the Control group. VEGF expressions were also increased in Onchung-Um treated group. This study has therefore demonstrated the Onchung-Um can significantly improve the quality of wound healing and scar formation and the oral administration of Onchung-Um extract may increase early tissue angiogenesis in the incisional wound of an experimental animal model.

Purpose: The purpose of this study is to propose useful suggestions by analyzing the causal effect relationship between the failure rate of quality and the process variables in the C5ISR domain of the defense industry. Methods: The collected data through the in house Systems were analyzed using Big data analysis. Data analysis between quality data and A/S history data was conducted using the CRISP-DM(Cross-Industry Standard Process for Data Mining) analysis process. Results: The results of this study are as follows: After evaluating the performance of candidate models for the influence of inspection data and A/S history data, logistic regression was selected as the final model because it performed relatively well compared to the decision tree with an accuracy of 82%/67% and an AUC of 0.66/0.57. Based on this model, we estimated the coefficients using 'R', a data analysis tool, and found that a specific variable(continuous maximum discharge current time) had a statistically significant effect on the A/S quality failure rate and it was analysed that 82% of the failure rate could be predicted. Conclusion: As the first case of applying big data analysis to quality issues in the defense industry, this study confirms that it is possible to improve the market failure rates of defense products by focusing on the measured values of the main causes of failures derived through the big data analysis process, and identifies improvements, such as the number of data samples and data collection limitations, to be addressed in subsequent studies for a more reliable analysis model.

Grain filling is a crucial factor that determines grain yield in crops since it is the final process directly associated with crops' yield performance. Grain filling process can be characterized by the interaction of rate and duration of grain filling. This study was conducted, using 16 temperate japonica rice genotypes, with aims to (1) seek variations in grain filling duration and rate on area basis, (2) compare the contribution of grain filling duration and rate to grain yield, and (3) examine the influence of temperature and solar radiation for effective grain filling on grain yield in relation to grain filling duration and rate. Grain filling rate and duration exhibited highly significant variations in the ranges of $20.7{\sim}46.3\;g\;m^{-2}d^{-1}\;and\;11.2{\sim}35.5$ days, respectively, depending on rice genotypes. Grain yield on unit area basis was associated positively with grain filling duration but negatively with grain filling rate. Grain filling rate and duration were negatively correlated with each other. Final grain weight increased linearly with the rise in both cumulative mean temperature and cumulative solar radiation for effective grain filling. Higher cumulative mean temperature and cumulative solar radiation for effective grain filling were the results of longer grain filling duration, but not necessarily higher daily mean temperature and daily solar radiation for effective grain filling. Grain filling rate demonstrated an increasing tendency with the rise in daily mean temperature for effective grain filling but their relationship was not obviously clear. It was concluded that grain filling duration, which influenced cumulative mean temperature and cumulative solar radiation for effective grain filling, was the main factor that determined grain yield on unit area basis in temperate Japonica rice.
