Science and technology is the power of impelling the economic and social development. Promoting the international sci-tech communication and cooperation is one of the important ways of pulling the economic development of Northeast Asia area. Sci-tech communication and cooperation between the government and the folk are two wings of international sci-tech communication and cooperation. Both are supplemented mutually and indispensable. In order to promote the economic and social development of Northeast Asia area and further strength, some suggestions are put forward, i.e.fully exerting university the main roles in the sci-tech communication and cooperation of Northeast Asia area and fully exerting Liaoning province the important roles in the sci-tech communication and cooperation of Northeast Asia area.

Objective: This study examined that general characteristics such as gender, age, period of stay at an institution, size of facility, and temperament and attachment affect young children's development under institutional care. Methods: A total of 94 young children (ages 2-4years), who live in 32 institutions in Seoul were assessed on their development using the Korean-Age & Stage Questionnaire. Pearson productmoment correlation analysis, and multiple regression analyses were used for data analysis. Results: The major findings of this study were as follows: first, a longer period of stay at an institution had more positive effects on the development of communication. Facilities with more than 60 children had lower communication, gross motor, and fine motor development compared to facilities with less than 60 children. Second, social temperament had positive effects on communication, problem solving, and personal-social development. Emotional temperament had no effects on all development areas. Third, attachment had positive effects on all development areas. Lastly, social temperament and attachment had interactive effects on communication, gross motor, problem solving, and personal-social development. Conclusion: These results imply that caretakers in institutions should give developmental mediation services for considering temperament and facilitation of attachment.

오늘의 社會는 多樣한 通信方式을 必要로 하는 社會的 欲求로 말미암아 Communication의 機能도 많은 樣相의 變遷過程을 거치고 있다. 旣存文明의 形態는 매스컴의 發展에 依하여 情報化된 社會로 變形되어가고 情報利用의 價値性도 그 依存度가 높아짐에 따라서 測定할 수 없는 경지에까지 이르렀다. 特히 情報機械의 發展에 따라서 情報利用의 急進的으로 擴大되어 가고 아울러 情報處理技術의 發展은 通信發達의 原因이 되면서 이 兩者의 相互的인 作用은 Communication機能의 變遷을 招來하게 되었다. 이와 같은 Communication機能의 變遷過程을 社會的 側面에서 考察함으로써 Communication 發展上 하나의 課題로 提示해 보고자 한다.

Purpose: Sex education should be given priority to address dating violence. Comprehensive sex education has been developed based on a nonviolent communication model between couples for the smooth resolution of problems with the opposite sex. The purpose of this study was to develop and apply Comprehensive Sex Education for unmarried couples in their 20s-30s and to examine the effects on sex communication, problem-solving communication, and relationship competence. Methods: This study developed a total of six web-based sex education sessions. A comprehensive sex education program combined with nonviolent communication between couples was developed based on the UNESCO Sex Education Guidelines. A pre- and post-equivalence control design was used to provide moderation-based sex education to compare the effects on gender communication, communication dissatisfaction, and relationship development. Results: We developed a comprehensive sex education program for couples that took three minutes per episode, on a web-based basis. Sex communication, problem-solving communication, and love relationship competence showed significant pre- and post-test differences between the experimental and control groups. Conclusion: The program of this study is an attempt to introduce Korea to comprehensive sex education, which has already been shown to be effective through numerous verification processes abroad and will provide assistance in forming future relationships between lovers.

Modern military operations rely heavily on broadband communication and data transmission. Recently, the rising use of intelligent unmanned technology necessitates more frequencies. Free-space optical(FSO) communication can offer high-data-rate communications with high security and no need for licensing. Therefore, the FSO communication holds significant interest and potential in the defense industry. In this paper, we present design of a FSO communication terminal taking Korean domestic weather conditions into account. The domestic atmospheric attenuation is analyzed using several models and two-year meteorological information for a city in Korea, and this analysis is utilized to design the FSO communication terminal. The design results were verified using an FSO communication test bed, and we achieved an Ethernet bandwidth of approximately 1.86 Gbps at a distance of 1.3 km with the optical amplifier output power of the test bed set to about 20 dBm.

Currently, our society is showing many changes due to the influence of information and communication technology (ICT). At the center of these information and communication technologies are software, intelligence, and sensing technologies. The software-related industry is steadily developing due to various software development policies implemented by the government and related organizations. Software development is desirable, but on the other hand, some negative aspects are also appearing. In this study, we proposed an objective way to infer the progress of software development for reasonable resolution of cases when a dispute related to the progress of development occurred during the software development process. The proposed solution was based on the waterfall model. The outputs generated in each process of the waterfall model are contents excluded from subjectivity. Therefore, it can be used as an objective method for calculating software development progress.

In this paper, we studied a method of wirelessly checking up the POD for captive flight tests which is performed during the development of guided weapons systems. The wireless power transfer module, the power distribution device, and the battery pack were designed to wirelessly power the captive flight test POD, and the communication device was designed to enable wireless communication between the POD and the check-up device. The communication device was designed to enable WiFi, IR communication, and laser diode communication, so that various communication methods could be tested. Through the performance test, it was confirmed that power was stably supplied to the captive flight test POD, and the wireless communication performance was verified by measuring the delay time and error rate. As a result, by using our system the POD check-up for the captive flight test was performed wirelessly and the data of the captive equipment could be obtained effectively.

In wireless environments, wideband receivers are used in a communication intelligent system to detect unknown signals and obtain azimuth information. To design a wideband receiver that performs multiple signal detection and direction finding simultaneously, it is necessary to consider a reception structure composed of multiple channels. In this paper, we propose a wideband multi-channel receiver for direction finding of unknown wideband communication signals including frequency hopping signals. A signal processing method for detecting received signals and estimating azimuth information is presented, and components of the manufactured wideband receiver are described. In addition, test results of the signal detection performance by mounting the proposed wideband multi-channel receiver on the flight system are included.
