The purpose of this study was to investigate the correlation amongst the social function, communication function, activities of daily living and gross motor function beyond existing research on physical function and functional capacity in cerebral palsy. 43 children with cerebral palsy participated in this study and significant correlations were found among social function, communication function, activities of daily living and gross motor function. The greatest significant correlations were found between social function and activities of daily living. Significant higher correlations were found between items of social function and communication, but were lower between social function and gross motor function. The results showed that we consider the social aspects of function of children with cerebral palsy in the area of rehabilitation in order to focus on the problem in real life.

Purpose: This study was done to examine the relationship between sexual permissiveness, family function and parent-adolescent communication among adolescents. Method: A descriptive correlation approach was used and the participants were 956 male and female students. Data were collected by questionnaire survey using convenience sampling. The instruments were the Family APGAR Questionnaire by Smilkstein(1978), PAC by Olson and Barnes(1982), and the Premarital Sexual Permissiveness Questionnaire by Reiss(1967). Data were analyzed using the SPSS 10.0 program with descriptive statistics, Pearson correlation coefficients, t-test, and ANOVA. Results: Family function was significant according to school record, economic status, living arrangement of parent. Parent-Adolescent Communication was significant according to religion, economic status, having a boy/girl friend, and experience of sexual intercourse. Sexual permissiveness was significant for all except economic status. Correlation among the variables showed that parent-adolescent communication was negatively correlated to sexual permissiveness(r=-.127, p=.000) and positively to family function(r=.368, p=.000). Conclusion: The findings suggest that parent-adolescent communication and family function are associated with sexual permissiveness, and the findings of this study are expected to make a contribution to creating an ideal sexual culture for youth.

This study identifies correlations between the use of media devices, communication ability, and executive function difficulties for third grade students, as well as investigates the moderating effect of a child's communication ability. Data from the 10th (2017) Panel Study on Korean Children [PSKC] was employed (N=557). Descriptive statistics, Pearson's correlation and hierarchical regression were used along with SPSS 25.0(IBM Co., Armonk, NY, USA). The results were as follows. First, the executive function difficulties in the third-grade showed a significant positive correlation with media device use. While also, showing a negative correlation with a child's communication ability. Media devices use and communication ability has a significant negative correlation. Second, a child's communication ability has a moderating effect in relation to the use of media devices and executive function difficulties. The difficulty of executive function showed a reciprocal increase to a child's use of media devices and indicated a discriminatory effect of a child's communication ability. In conclusion, this study shows that communication ability is important as a personal factor for children who control the negative effects of media devices. Therefore, it is necessary to provide and support an environment for the development of a child's communication ability.

Several falling-sensing terminals have been developed which are able to detect the fall/upset accident of the elderly and transmit the collapsing signals to the administrative server via RF communication using 400MHz bandwidth. Supposing there might be no communication problem within a sanatorium, just single terminal without relay function had been made as a prototype in the first stage of development. However some communication problems have discovered at the coner of the floor apart from the other floor diagonally in the same building. Same kind of problems have been happened in the area behind a steel fence or a car. To solve these kinds of communication problems, we have developed several terminals and added up relay function to them. In this paper we represented that the success ratio of the communication has been improved by using relay function among several terminals.

In Korea, we still use function point based cost estimations for software size and cost of a project. The current problem is that we make difficultly calculating function points with requirements and also have less accurate. That is, it is difficult for non-experts to analyze requirements and calculate function point values with them, and even experts often derive different function points. In addition, all stakeholders strongly make the validity and accuracy of the function point values of the project before /after the development is completed. There are methods for performing function point analysis using source code [1][2][3][4] and some researchers [5][6][7] attempt empirical verification of function points about the estimated cost. There is no research on automatic cost validation with source code after the final development is completed. In this paper, we propose automatically how to calculate Function Points based on natural language requirements before development and prove FP calculation based on the final source code after development. We expect validation by comparing the function scores calculated by forward engineering and reverse engineering methods.

This paper presents two methods of designing a Broadband Impedance Matching (BIM) circuit for maximizing a power line communication (PLC) equipment (or Modem) signal injection into its load at any power line connection port. This optimal (BIM) circuit design is achieved in two phases: Butterworth gain function and Tchebycheff gain function. According to the comparison of simulation and practical results, the performances of two gain functions on BIM are discussed.

Purpose: The aim of this study was to examine the factors that affect nurses' communication. Methods: This study employed a descriptive survey design. The sample of this study consisted of 174 nurses at hospital in Korea from June 1st to 18th, 2009. The data were analyzed SPSS/WIN 17.0 program and factors affecting nurses' communication were analyzed by multiple regression. Results: 1) Level of nurses' communication was average of 3.44, ego strength 0.36, self-image 3.53, ego distribution 2.92, interpersonal relations 3.52, and family function 3.39. 2) Nurses' communication had significant positive correlation with interpersonal relations, self-image, family function, and ego strength. On the other hand, it had not significant correlation with ego distribution. 3) Interpersonal relations (t=9.68, p<.001), ego strength (t=3.11, p=.002), and family function (t=2.26, p=.025) significantly predicted the level of nurses' communication (Adjusted $R^2$=.418, p<.001). Conclusion: The study finding suggested to develop hospitals' management program for increasing nurses' communication.

The smart convergence environment, in which all industries are converged around ICT infrastructure -- with the eventual inclusion of both industry and culture -- looms. With the emergence of new convergence industries such as smart medicine, smart cities, and smart automobiles, the ICT infrastructure is recognized as the foundation of the overall economy. As such, the importance of the next generation of information and communication construction businesses, which constructs the ICT infrastructure, is highlighted under the smart convergence paradigm environment; various multilateral policies to foster the information and communication construction business -- led by the Ministry of Science, ICT, and Future Planning -- are being implemented. Like other infrastructure industries, however, the estimation of the demand function of the information and communication construction business overall is essential for effectively establishing promotional policies for information and communication construction businesses. However, there has been no study which theoretically estimates the market demand function in the information and communication construction business thus far. The pursuit of a creative economy is a national agenda, as the significance of accelerating the ICT infrastructure is emphasized. Therefore, this paper seeks to estimate quantitatively the demand function in the information and communication construction business using empirical data and a statistical model and then to present policy implications which will aid the development of the information and communication construction business.

Purpose: It remains controversial for the effect of daily functioning and quality of life on therapeutic exercise after stroke. The purpose of this study was to describe the effects on daily functioning and QOL. Methods: Outcome measures of daily functioning included, such as the Functional Independence Measure (FIM), Barthel index. Outcome measures of QOL included, such as Stroke Impact Scale(SIS) and the Medical Outcomes Study short-form 36-item questionnaire(SF-36). Results: 125 stroke patients were recruited, who were in or outpatients. The average age was 55.4 years. 64.8% were male. The mean Bathel index and FIM score was 63.7 and 87.5. The mean SIS score were higher in communication and mean SF-36 score were higher in physical pain. In/out patients are associated with SIS (communication, emotion) and SF-36(social function, energy or fatigue). Sex are associated with SF-36 (physical function). Other disease state are associated with SIS(hand function) and SF-36 (physical function). Paralysis portion are associated with SIS(communication, daily activity). Barthel index are associated with SIS(communication, mobility) and SF-36(social function, physical function, role limits due to emotional problems). Conclusion: These findings may provide the useful with rehabilitation professionals, who specilalized in the importance of QOL in designing treatment modalities.

We generalize the widebane P0-weyl symbol (P0WS) and the widebane spreading function (WSF) using the generalized warping function . The new generalized P0WS and WSF are useful for analyzing system and communication channels producing generalized time shifts. We also investigated the relationship between the affine Wey1 symbol(AWS) and the P0WS. By using specific warping functions, we derive new P0WS and WSF as analysis tools for systems and communication channels with non-linear group delary characteristics. The new P0WS preserves specific types of changes imposed on random processes. The new WSF provides a new interpretation of output of system and communication channel as weighted superpositions of non-linear time shifts on the input. It is compared to the conventional method obtaining output of system and communication channel as a convention integration of the input with the impulse response of the system and the communication channel. The convolution integration can be interpreted as weighted superpositions of liner time shifts on the input where the weight is the impulse response of the system and the communication channel. Application examples in analysis and detection demonstrate the advantages of our new results.
