The impact of the information technology industry on economic development is becoming increasingly important. In this study, we take China's provincial-level regions from 2015 to 2020 as the research object, comprehensively evaluates the level of their information technology systems by the entropy weight method, and then measures the coupling coordination relationship between the information technology system and the economic development system by the coupling coordination degree model. As a result, we found that the income of the information technology industry, the investment of talents and science research have the most important influence on the level of the information technology system. During the research period, with increasing values, the coupling degree of the two systems was at a high level. Affected by development strategies, diffusion effects and industrial relocation, the coupling degree in the central and western regions has shown a rapid growth trend. The coordination degree of the two systems is relatively low, and 83.9% of the provinces are in the medium-low coordination stage. The information technology industry has obviously promoted economic development. Besides, relevant policies should be introduced to effectively support and guide the high-quality development of the information technology industry and promote the high-level coordinated development of the two systems.

This study was conducted to evaluate the degree of value assigned to traditional Korean foods by residents from the Kyunggi(n=582) and Kangwon(n=189) areas of Korea. We determined the degree of value for 13 items classified as traditional Korean foods by asking subjects to score the items based on a 5 point Likert scale. Based on the total scores, resident in Kyunggi assigned Kimchi the high degree of value. Next was Tteok, then Eum-cheong, Jang, Hankwa, Muk, Bap, Jeon, Namul, and Guk, respectively. In the Kangwon area, the total scores showed that Kimchi also had the highest degree of value, followed by Tteok, Jang, Hankwa, Eum-Cheong, Muk, Bap, Namul, Jeon and Myeon, respectively. The female residents in Kyunggi gave Kimchi a higher degree of value than the male residents'. Also, subjects with overall higher positive perception of traditional foods had a higher degree of value for Kimchi. Relative to age, ther was a trend showing older subjects had a higher degree of value for Kimchi than Younger subjects. In the case of the head of the family, residents of the Kangwon area showed a trend toward a high degree of value for Kimchi. The residents in Kyunggi, compared to the residents in Kangwon, evaluated the Jang food group as inexpensive foods(p<0.05). However, there was no significant difference between the residence areas for the total score of the items. Overall, the resident's evaluation of the degree of value traditional Korean foods increased with increasing age.

In the Core Technology R&D of the defence area, the development of the related core element technology could be the foundation to develop advanced weapon system in the future. But it might make various problems if you can not accurately define the TRL of the element technology. In other words, if the technology is not sufficiently mature and then the project starts, it might require an increase in the development period and additional cost. Finally the system will be in an incomplete state and result in user dissatisfaction and the project failure. Therefore it is a very important task to properly assess the TRL for a successful project. In this study, We propose the method for risk management of core technology R&D project of the defence area using the QFD process with degree of difficulty and technology readiness level. It is also presented the process to determine the risk level using TRL and Degree of difficulty. Finally We apply this method to UGV system for verifying the result of this study.

The purpose of the present study was to investigate the relationship between children's aggression, their anger regulation strategy and anger regulation degree. Using an aggression scale, a total of 428 elementary school children in grades 5 and 6 were examined and partitioned into two groups; -the high aggression group (n = 107) and low aggression group (n = 109). They rated the degree to which they felt anger in anger events. They selected one strategy used to regulate anger. Then they rated the degree to which they felt anger after using the selected regulation strategy. The results of this study showed that the high aggression group responded by high degree of anger, low degree of anger regulation and used more affect diffusion strategy. Regardless of children's aggression source, support pursuit strategy was confirmed to be the most effective remedial method while children regulated anger in anger events.

A High-degree Cubature Kalman Filter (CKF) is proposed to deal with the Strapdown Inertial Navigation System (SDINS) alignment problem. In-flight Alignment (IFA) is an effective method to compensate for attitude errors of the navigation system. While providing precise attitude error compensation, however, the external source aided alignment often creates a nonlinear filtering problem caused by a large misalignment angle. Introduced recently, Cubature Kalman Filter is a suitable technique for various nonlinear problems. In this paper, a higher degree CKF is applied to this accuracy-is-everything SDINS IFA problem. The simulation results show that the proposed technique outperformed a traditional nonlinear filter in terms of precision and alignment time.

Influence of soil temperature [accumulated degree-day for the base temperature $5^{\circ}$($\textrm{DD}_5$)] on the development of Meloidogyne arenaria were studied in a winter grown oriental melon greenhouse in Seongju, Korea. Egg masses were first observed on roots at the accumulation of 565 $\textrm{DD}_5$(40 days after transplanting), suggesting that the nematode has completed the first generation in 40 days. Second-stage juveniles (J2) densities were lowest at 863 $\textrm{DD}_5$ in April, first increased at 1,334 $\textrm{DD}_5$ in May, peaked at 2,951 $\textrm{DD}_5$ in July, and decliner thereafter. Development of egg masses and J2 density in soil revealed that M. arenaria could develop in 7-8 generations in a year in the greenhouse. Degree-day monitoring, therefore, could aid to predict nematode development in soil and can be valuable tool a to develop root-knot nematode control strategies.

To quantitatively assess the correlation between subsystems within a port cluster and the overall coordinated development of the port group, the current paper evaluates the coordinated development of port clusters. First, we construct an evaluation index system for the coupling and coordination of port clusters. Next, we introduce the contribution index of port subsystems, coupling degree, and coupling coordination degree functions to formulate a coupling coordination evaluation model for the port cluster. Finally, we use the Yangtze River Delta port cluster as a case study for validation, specifically using empirical data from 2012 to 2021. The findings reveal distinct phased characteristics in the coupling and coordination of port clusters in the Yangtze River Delta, marked by a notable transition from "maladjustment" to "coordination." Further, sustained high coupling values over a decade indicate a significant level of competition and cooperation among ports within the Yangtze River Delta port cluster. Over time, this competitive and collaborative dynamic has progressively evolved toward a more positive and structured direction. Lastly, it is expected that the evaluation model proposed in this paper can be extrapolated to other port clusters to gauge the extent of coordinated development, thereby facilitating horizontal comparisons and vertical analyses.

The purpose of this study was to identify therapeutic play need and the degree of the nurses's therapeutic play performances perceived by hospitalized children's mothers, and then to compare the difference between the degree of the need and perceived performances. The subjects of this study consist of 121 hospitalized children's mothers. A questionaire for this study was 29 item likert type 4 point scale developed on the basis of literature review, hospitalized children's mother interview and researcher's clinical experiences. Data was analyzed by Paired t-test, t-test, ANOVA & Duncan's comparison. Results of this study are summarized as follows : 1. The degree of the therapeutic play need was measured to be high (3.20). The degree of perceived therapeutic play need by five components were followed as : physiologic suffering relief & enhancing play (3.39), growth & development facilitating play (3.26), instructional play (3.24), emotional well-being promoting play (3.18) and providing play tool & environment(2.97). 2.The degree of the nurse's therapeutic play performances perceived by mothers was measured to be low (1.60). The degree of perceived performances of the therapeutic play by the five components were followed as : physiologic suffering relief & enhancing play (1.87), instructional play (1.74), emotional well-being promoting play (1.64), providing play tool & environment (1.44) and growth&development facilitating play (1.42). 3. The difference between the degree of the therapeutic play need and nurese's perfor- mances perceived by hospitalized children's mothers were significant statistically (t= 38.54, p=.0001). Also, five components of therapeutic play were significant statistically (p=.0001). Therapeutic play has unique benefits among health care intervention for children. These findings will help in building of the theoretical framework of therapeutic play and enhancing the quality of nursing care for hospitalized children. Therapeutic play program for hospitalized children according to child growth & development and physiologic status are recommended to be developed.
