To verify the trustworthiness of messages, public key certificates and certificate revocation list(CRL) has been standardized for vehicular networks. However, timely distribution of large CRLs to vehicles should be more elaborated with low bandwidth utilization from a practical point of view. To address this concern, we propose a CRL distribution scheme using long term evolution(LTE) point-to-multicast transmission, namely the enhanced multimedia broadcast multicast service(eMBMS). The schem is much more resource efficient than the existing unicast CRL distribution schemes for vehicular networks and it allows realizing the regional CRL distribution schemes efficiently in LTE network. By means of ns-3 simulation, we analyze the performance, latency, and execution time of the scheme in terms of varying coverage of the multimedia broadcast multicast service over single frequency network (MBFSN).

Purpose: This study aimed to investigate the work and job satisfaction of military emergency medical technicians (EMTs). Methods: We selected 122 military EMTs who participated in the refresher education in 2012. This study was conducted from November 12 to December 21, 2012. Results: The most frequent duties of military EMTs were scene assessment, cardiopulmonary resuscitation, surgical treatment, prehospital first-aid, transfer to the hospital, education, and call response. The air force and navy EMTs had better performance than the army EMTs. As for job satisfaction, the work itself ranked highest, whereas payment ranked lowest. Conclusion: The scope of the work of the military EMTs varied in the 14 fields of work but should be considered for further evaluation. In order to increase the job satisfaction of EMTs, their work conditions should be improved such as through salary increase and extra pay for those with professional certificates.

The educational process and result of onboard training should be evaluated according to the 1995 Amendments to the International Convention on Standards of Training, Certification and Watch-keeping for seafarers(STCW), 1978. In particular, the revised Convention requires that a trainee's seagoing service must be recorded in each cadet's Training Record Book approved by the maritime administration responsible for the issuance of certificates of competency. Trainees for certification under regulation III/1 of the STCW Convention are required to complete an approved on-board training programme. The purpose of this paper is to understand the compliance of the education for an approved on-board training programme. The questionnaire was distributed among 110 cadets being trained on board the training ship of the maritime college of the Mokpo National Maritime University. In this study, we conducted the questionnaire survey which is related to the on-board training programme such as marine engineering; controlling the operation of the ship and care for persons on board; electrical, electronic and control engineering; etc. The survey revealed that onboard training program was normally satisfactory, however, lack of practical training tools and time have accounted for most of the reasons for dissatisfaction. Therefore, it is our goal to enhance the satisfactory value of onboard training education by analyzing the reason of the dissatisfaction.

After analyzing the integrated indication subjects related with fisheries & Maritime high school, among the middle school teacher's 24 subjects of industrial world, the problems and improvements can be arranged as followed. Firstly, the subjects of fisheries & Maritime high school teacher's certificates are fishing industry, aquiculture, sailing, engine and freezing and new subjects are ocean shipping and ocean logistics. Because the teacher's certificate was changed to integrated indication subjects, there were problems of teacher cultivation, teacher hiring, etc. So, in the actual field of school, teacher cultivating university and related department are necessary to strengthen high-quality majoring education/subjects and practical education as well as need to establish teacher cultivating system by teacher cultivating organization's evaluation system and teacher cultivating education program related by differentiation and easiness of majoring characterization. Secondly, teacher cultivating for new departments and new subjects can apply related major system, free major system, etc. Thirdly, if professional high schools find majoring areas whose content is same one another and introduce common indication subject system, it will be helpful to improve the quality of teachers, teacher certification examination, etc. of professional area.

30여 년의 결코 짧지 않은 실용음악과 역사 속에서 수많은 졸업생들이 배출되었음에도 불구하고 학생들의 취업은 여전히 풀 수 없는 과제로 남아있다. 졸업생들의 대부분이 학원 강사 혹은 밴드활동 등으로 취업을 하게 되는데, 모두 안정적 생활을 기대할 수 없는 비정규직이다. 국력신장과 더불어 K-POP의 비약적인 발전은 우리의 삶 또한 바꿔놓았고 그로 인해 과거, 사치로만 인식되었던 문화 예술분야가 대중에게 급격히 다가오게 되었다. 단순히 관람만이 아닌 직접 배우고, 익히고, 체험하는 형태로 우리 삶의 질 향상에 매우 큰 영향을 끼치고 있다. 이는 국가적인 정책에도 반영되어, 초, 중, 고등학교에서의 문화예술분야 교육프로그램운영을 비롯한 각 지역 주민센터에서 주민복지 향상을 위한 예술프로그램 운영 등으로 나타나고 있다. 이젠 해당 분야로도 취업 안목을 넓혀야 할 것이며, 이에 따라 자격증 취득관련프로그램을 활성화시켜 취업에 도움이 될 수 있도록 매진해야 할 것이다. 이와 아울러 현재의 음악전공 중등교사 자격증과는 다른 실용음악분야 중등교사 자격증 과정을 만들어야 한다. 4년제 대학의 교직과정 이수, 혹은 실용음악 전문 교육 대학원 설립 등이 매우 절실한 상황이다.

This study examined differences in consumers' images of short-term income forest products, preference, willingness to pay prices and purchase behavior according to dietary lifestyle as well as investigated what factors influence the degree of satisfaction when purchasing short-term income forest products and willingness to repurchase. According to dietary lifestyle, the results classified consumers as 'frugal housewife type,' 'convenience-seeking type,' and 'food high-involvement type.' A 'food high-involvement group' is defined as a group that wants high quality products regardless of price. In the 'frugal housewife type,' country of origin and hygiene/safety (considered when purchasing food) had positive influences on the degree of satisfaction. In the 'convenience-seeking type,' country of origin (considered when purchasing food) had a positive influence on the degree of satisfaction while country of origin (checked when purchasing food) had a negative influence on degree of satisfaction. Consumers had a lack of perception for short-term income forest products; subsequently, short-term income forest products had a weakness of low access to consumers. Therefore, farms for short-term income forest products need to divide products into 'high-priced' luxury products and 'low-priced' frugal products according to dietary lifestyle characteristics, improve packaging status to enable consumers to check quality certificates, and clearly indicate country of origin as well as improve distribution processes and increase consumer access to products.

Use of security papers for monetary papers, gift certificates, and lottery tickets increases every year. As the use of security papers increase, there are more possibility of counterfeits. In this study, we used unique fibers from the sea to increase the difficulties against counterfeiting. The red algae fibers give opacity as much as calcium carbonates, and have unique shape in length ($500{\sim}900\;{\mu}m$) and width ($1{\sim}4\;{\mu}m$) to be discerned from other natural fibers such as wood and cotton fibers. We mixed red algae fibers to wood fibers in a series of fixed ratios to make single and multiply papers for making security papers. Paper with dyed red algae fibers were also used. Paper made without fillers gave enough opacity for printing when red algae fibers were used more than 20% of the fiber furnish. Those properties may allow red algae fibers to be a potential candidate for fiber raw materials of security paper.
