The purposes of this research were to investigate the conditions of education and counseling for single-parent families and to propose developmental alternatives and effective information service system. For these objectives, the concurrent-type program for single-parent families that emphasized communication skills, psychological strategies, and the importance of family relationships was constructed. The effectiveness of the program was evaluated by pre-, post test through 163 single parents and their children and it was analyzed by paired t-test. The results suggested that the program was effective in improving self-esteem, satisfaction of life and communication. Several programs for single-parent families using on-line or off-line were analyzed and more effective alternatives were proposed. For improving of wellbeing of single-parent families, the welfare system must be changed to cooperation with other institutions and systematic information service network.

Kappa number and brightness were more increased with treatment of endo-xylanase than hydrogen-peroxide. In pulp bleaching process, endo-xylanse was most effective in the other enzyme treatment. Exo-xylanase was effective more than 4 unit treatment. Kappa number was tiny increased with enzyme ratio, but less than 4 unit treatment, increased with hydrogen peroxide treatment ratio. In more than 4 unit acetyl-estease treatment, Kappa number and brightness were not influenced with enzyme treatment ratio, but concentration of hydrogen-peroxide.

Objectives: The purpose of the study was to develop communication strategies for effective nutrition education targeting pregnant women and to create nutrition education contents. Methods: The format and the contents of online resources on nutrition information for pregnant women provided by reliable institutions were analyzed. Possible solutions to overcome barriers of nutrition education as well as communication strategies for effective nutrition education were identified by a brainstorming process. Based on the communication strategies, contents for nutrition education were created. Understandability, level of interest, applicability to daily life, harmony of text and illustration, and overall satisfaction of the contents were evaluated by dietitians and pregnant women. Results: The four communication strategies were developed; (1) to focus on a few important messages, (2) to provide evidence-based information, (3) to create illustrations or infographics with a minimum amount of text, and (4) to provide tips on how to improve the current diet options. Based on these strategies, the contents were focused on three important nutrients for pregnant women, folate, iron, and calcium. The percentages of the recommended nutrient intakes of the three nutrients on selected menu and its improved version by adding a dish or changing a dish into another dish were calculated and provided. Finally, the contents were delivered as illustrations with a minimum amount of text. Overall, dietitians and pregnant women were satisfied with the contents. Conclusions: The contents developed in this study can be used in a pamphlet or a pregnancy diary, or can be shared in social networking services. Further contents on other nutrients and various menu are expected to be developed using these communication strategies.

Objectives : The purpose of this study was to help form treatment relationship with patient through more effective communication by defining the relationship between dental hygienist's medical communication and outpatient's reliance satisfaction. Methods : The study researched 273 male and female patients who visited dental clinics and hospitals of Busan from March 12 to March 26, 2012 and its results are as follows. Results : 1. The linguistic communication of dental hygienist was $3.72{\pm}0.63$ and non-linguistic communication was $3.48{\pm}0.58$. 2. For the dental hygienist's reliance satisfaction, the reliance was $3.62{\pm}0.65$ and the satisfaction was $3.74{\pm}0.65$. 3. The dental hygienist's communication degree depending on general characteristic was statistically significant when the job of patient was housewife(p<0.001) and the number of dental clinic visits was more than 10 times (p<0.000). The dental hygienist's non-linguistic communication was statistically significant depending on patient's gender(p<0.000), age(p<0.002), job(p<0.001) and number of dental clinic visits (p<0.000). 4. The dental hygienist's reliance and satisfaction showed statistically significant difference depending on patient's gender(p<0.000), age(p<0.002), job(p<0.001) and number of dental clinic visits (p<0.000). 5. The dental hygienist's non-linguistic communication showed a positive correlation with reliance and satisfaction(p=0.000). Conclusions : When considering the result above, it is necessary to develop the teaching method and material to educate the communication ability of dental manpower. It is necessary to reinforce the curriculum of dental hygienics and the education of dental hygienist to perform effective, smooth communication between dental hygienists.

Effective internal communication is known to have a positive impact on business performance, but there is a lack of research on the effects of online channels for workplace communication. This study using regression analysis examines how task-technology fit, information richness, self-efficacy, perceived ease of use, and perceived usefulness related to online communication channels affect not only the satisfaction with the tools but also the effectiveness of them. Additionally, we verify how the organizational culture of online and offline communication shows the control effect. As a result, all five variables were positively correlated with internal communication channels satisfaction, and we found that the organizational culture of online and offline communication controls the relationship between online communication channels satisfaction and effectiveness.

Objectives: The purpose of this study is to obtain basic data on the development of a risk communication model through an investigation of risk perception for radon and identify effective risk communication channels. Methods: A questionnaire was used to evaluate differences in perception level according to respective communication channels. A chi-squared test was used to analyze the difference in pre- and post-risk communication by communication channel. One-way ANOVA was used to analyze the difference in the radon risk perception rate for each communication channel. Results: All of the communication channels resulted in increased radon risk perception, but there was no statistical difference between them in terms of perception (p>0.05). However, based on previous findings that it is effective to use a multi-channel approach, it is considered that communication channels based on duplicate avenues is most appropriate. Conclusions: It is expected that this study will be used as basic data to better understand the formation of public opinion about radon risk and to understand the social reaction to each risk factor.

Although an ideal low-pass filter is not physically realizable, it can be approximated on the basis of time reversal techniques. In this paper, we describe a method to approximately implement the ideal low-pass filter and apply it to the pitch extraction system. Experimental results show that our method is effective to estimate the fundamental frequency of the speech signal.

In a Satellite communication system, a link budget analysis is the detailed investigation of signal gains and losses moving through a channel from a sender to receiver. It inspects the fading of passed on data signal waves due to the process of spreading or propagation, including transmitter and receiver antenna gains, feeder cables, and related losses. The extent of the proposed tool is to make an effective, efficient, and user-friendly approach to calculate link budget analysis. It is also related to the satellite communication correlation framework by building up a graphical interface link analysis tool utilizing STK^® software with the interface of C# programming. It provides better kinds of graphical display techniques, exporting and importing data files, printing link information, access data, azimuth-elevation-range (AER), and simulation is also possible at once. The components of the link budget analysis tool include transmitter gain, effective isotropic radiated power (EIRP), free space loss, propagation loss, frequency Doppler shift, flux density, link margin, elevation plot, etc. This tool can be useful for amateur users (e.g., CubeSat developers in the universities) or nanosat developers who may not know about the RF communication system of the satellite and the orbital mechanics (e.g., orbit propagators) principle used in the satellite link analysis.
