The purpose of this study is to investigate the knowledge and recognition about blood donation and satisfaction, look for ways to promote the idea that effective, was trying to get the plan to provide the basis for the expanding population of voluntary and continuous blood donation. A survey was from May 9, 2012 to May 24, 2012 and total 636 copies were used as final study data. The data collected analyzed with SPSS win 21.0 using descriptive methods, frequency analysis, chi-square test, t-test, ANOVA. The results were as follows. First, the rates of the blood donors were higher in the men, in the age group from 20 to 29, in the students and in the group that received college or higher education. Second, as for the knowledge and recognition of the blood donors on blood donation, many replied they didn't know well about it. Concerning satisfaction level, they gave higher marks to satisfaction with related service than with blood donation itself. Third, the necessity of sustained blood donation promotion and education was pointed out. TV was most preferred, followed by ads on the street and ads on the subway. To expedite an increase in the blood-doner population, prolonged education and promotion are required to change the way that people in general look at blood donation, and a variety of rewards should be provided for blood donors.

Cluster-based routing is high energy consumption of cluster head nodes. A recent approach to resolving the problem is the dynamic cluster technique that periodically re-selects cluster head nodes to distribute energy consumption of the sensor nodes. However, the dynamic clustering technique has a problem that repetitive construction of clustering consumes the more energies. This paper proposes a solution to the problems described above from the energy efficiency perspective. The round-robin cluster header(RRCH) technique, which fixes the initially structured cluster and sequentially selects cluster head nodes, is suggested for solving the energy consumption problem regarding repetitive cluster construction. A simulation result were compared with the performances of two of the most widely used conventional techniques, the LEACH(Low Energy Adaptive Clustering Hierarchy) and HEED(Hybrid, Energy Efficient, Distributed Clustering) algorithms, based on energy consumption, remaining energy for each node and uniform distribution. The evaluation confirmed that in terms of energy consumption, the technique proposed in this paper was 26.5% and 20% more efficient than LEACH and HEED, respectively.

A viral marketing has been an effective marketing tool in various fields. In this study, we applied a viral marketing strategy for managing the Internet community website of scientists and engineers, KOSEN(www.kosen21.org). We developed a function that enables members to send promotional e-mails to their acquaintances, and we also designed a reward system for the members who participated in KOSEN viral marketing. With these strategies, KOSEN members reacted positively on the rewards (i.e., mileage points, gift card) and also the loyalty members took part in the viral marketing program more actively than other members. Furthermore, an attractive event was very effective for the prompt reaction of the viral marketing. Managing loyalty members is necessary for the continuous effects. The viral marketing strategies and analysis results of this research could be used for the management of an Internet service.

SNOMED CT is the most widely used comprehensive clinical terminology system worldwide. However, due to the vastness of the terminology and the continuous growth of medical knowledge, the system involve quality issues such as structural inaccuracies and inconsistencies, including missing concepts or relationships and hierarchical errors. In this paper, we propose a method to enhance the consistency of the system by detecting potentially missing concepts by utilizing attributes linked to concepts. The proposed method analyzes the characteristics of the attribute relationships of concepts, extracts sibling concepts that share the same characteristics, and then evaluates whether the parent concepts reflect these characteristics to detect potentially missing concepts. By applying this method to the March 2023 SNOMED CT international release, we identified 564 instances where parent concepts did not reflect the common attributes of their sibling concepts, and a total of 384 potentially missing concepts were detected, including cases involving multiple parent concepts.

Technology-based start-ups have great economic ripple effect such as economic growth and job creation. Therefore, a strategic approach is required in order for such start-ups to continuously grow. However, many technology-based start-ups do not survive the Death-Valley and are being eliminated from the market. This is an empirical study on influencing variables that have impact on their performance. This study presents growth intention and influencing variables that have impact on performance (financial performance, technological performance) based on previous research on technology-based start-up. Also, this study examines the relationship between entrepreneurial competence, team commitment and growth intention, and finds the effect of controlling business-network. Structural equation modeling was performed in order to test the research hypothesis. Survey was conducted on the firms that have been certified by Youth Startup Academy of Small and Medium Business Corporation. A total of 306 samples were collected from the survey. An empirical test was conducted on the research hypothesis using SPSS 21.0 and Amos 22.0. The result of hypothesis test shows that growth intention has positive influence on both financial and technological performance, and entrepreneurial competence (technological competence, strategic management competence, creative competence and team commitment) has positive influence on growth intention. Also, the research proved that business-network has regulation effect between human resource trait and growth intention. The result of our study will provide practical insight to future start-ups for continuous growth and successful running of their firm.

The purpose of the this study is to observe the effects of healthy adults' age on temporal features of speech and identify which could differentiate older and young adults. We examined speech rates(i.e., overall speaking rate, articulation rate), occurrence of pause, and duration of pause per utterance by utilizing the National Institute of Korean Language's open corpus. We selected a total of 30 healthy adults (10 young, 10 middle-aged, and 10 older adults) in this study. There were significant differences among the groups in the overall speaking rate, articulation rate, total occurrence of pause, the occurrence of pause between syntactic words, total duration of pause, and duration of pause between syntactic words. The older and middle-aged adults showed slower speech rates and longer and more frequent pause than young adults. But there were no significant differences among the three groups in terms of pause within syntactic word. The overall speaking rate significantly differentiated older adults from young adults. These findings suggested that the effect of speakers' age was reflected in gradual changes in the temporal features of their speech.

The purpose of this study was to determine the relationship between gymnasium selection and training adherence of security martial arts trainees. To this aim, this study selected 8 gymnasiums in Gyounggi and Incheon province and sampled 220 people above the fourth grade in elementary school. Out of these, 14 cases were dropped due to insufficient answers or incomplete answers, and 206 qualified cases were finally adopted for this study. Data were analyzed using exploratory factor analysis, reliability analysis and frequency analysis, MANOVA, correlation analysis and multiple regression analysis with SPSS 18.0. The results of this study were as follows. First, there were significant differences in gymnasium selection factors(instructor background, training program, public relations) depending upon the trainee's sex. Second, there were significant differences in gymnasium selection factors(training program, main others, public relations) depending upon the trainee's school grade. Third, there were no significant differences in training adherence factors depending upon the trainee's sex and school grade. Fourth, there were positive correlations between instructor background, training program and public relations-factors among gymnasium selection and management program, external and social relations-factors among training adherence. Fifth, the partial sub-factors of gymnasium selection have influenced training adherence. Consequently, security martial arts managers and instructors need to establish marketing strategies suitable for sex and school grade to recruit new security martial arts trainees. It may be considered that security martial arts instructors should construct the differentiated management system for trainees and the specialized training program for lasting training of new or existing security martial arts trainees.
