Illustration has been used as a means of human communication since the primitive age. And now it has become a way to express impliedly either the fragmentary or the psychological side of our life. Like it has been said in peter knock's Illustration magazine, an artist said "it was the best article ever read." Illustrator's task is to abstract and practically describe not our daily life, but every moment of the perception an object, whether it is define or indefine. It can inspire stronger perception than any other elegant language. Addition to that the practical use of illustration is increasing ever day. The target has now become various such as man, nature, art, science and so on. Therefore, at this point what illustration requires is creation, new and striking idea. It is because in order to get in to the general's living in the complicate and various society, it must show unique images and appearance. Therefore, now the illustration should induce the work which is based on synetics thoughts, not simple improving skill. Now we must restrain futional and diagrammatic illustration education and be able to thik of free and abundant characteristics. It will eventually help students to feel the value of human life and free themselves from the reality of present education which is getting machinized and instrumentalized.entalized.

This study was conducted to determine whether if the emotional response of participants influences senior citizens at a senior citizen center and to develop the qualities and skills of the instructors of the senior citizens. Not only will we provide effective materials but also provide basic materials as well. The emotional response of interpersonal relationships, achievement goal of ability to performance, and influence of orientating themselves. Additionally, the emotional response of interpersonal relationships, ability to concentrate, and confidence. Finally, the achievement goal of task orientation, concentration of ability to performance on orientating oneself, as well as confidence. Therefore, we will be able to determine if the emotional response of a participant influences achievement of a goal and of the effectiveness of senior citizen instructors. This will not only help with practical and cultural issues, but will close the distance between the instructors participants based on consideration of their situational aspects. Furthermore, the sports activities and continued participation of the elderly. Always need to be ready mentally, and rather than the consideration of others as well as the game results, it is important to have an interest in achieving their own standards. Instructors toned to lend support while setting goals for the participants so that they contribute to the personal development and overall quality of life of the participants.

This study is an attempt to look into the future role of the ROKN and to provide a strategic way forward with a special focus on naval strategic concept and force planning. To accomplish this goal, this research takes four sequential steps for analysis: 1) assessing the role and utility of naval power of ROKN since its foundation back in 1945; 2) forecasting features of various maritime threats to influence the security of Korea in the future directly or indirectly; 3) identifying the roles to be undertaken by future ROKN; and 4) recommending Korean way of naval force planning and the operational concept of naval power. This study seeks to show that ROKN needs comprehensive role to better serve the nation with respect to national security, national prosperity and development, and future battle-space management. To safeguard the national security of Korea, it suggests three roles: 1) national guard for the peaceful unification; 2) protector of the maritime sovereignty; and 3) suppressor to maritime threats. Three more roles are highlighted for national prosperity: 1) escort of the national economy; 2) guardian for national maritime activities; and 3) contributor to the world peace. These roles need to be closely connected with the role for the battle-space management. This paper addresses the need for a dramatic shift of the central operational domain from land to maritime in the future. This will eventually offer future ROKN a leading role for developing strategic concept and force planning rather than merely a supporting one. This study finally suggests 'balanced' strategy both in concept development and force planning. A balanced force planning is a 'must' rather than an 'option' when considering a division of function between Task Fleets and Area Fleets, constructing cutting-edge conventional forces such as Aegis destroyer, CVs, or submarines, and the mix of high-profile platform and low-profile when composing future fleets. A 'balance' is also needed in operational concept. The fleet should be prepared to fulfill its missions based on two different types of force operation i.e., coercive or cooperative application of the utility of naval force. The findings and recommendations of the study are relevant today, and will be increasingly important in the future to achieve various political goals required by enhancing the utility of naval power.

The secret sharing is the basic concept of the threshold cryptosystem and has an important position in the modern cryptography. At 1995, Jarecki proposed the proactive secret sharing to be a solution of existing the mobile adversary and also proposed the share renewal scheme for (k, n) threshold scheme. For n participants in the protocol, his method needs O($n^2$) modular exponentiation per one participant. It is very high computational cost and is not fit for the scalable cryptosystem. In this paper, we propose the efficient share renewal scheme that need only O(n) modular exponentiation per participant. And we prove our scheme is secure if less that ${\frac}\frac{1}{2}n-1$ adversaries exist and they static adversary.

This study focuses on the analysis of the changes of transport policies before and after the German Unification. It shows also the efficient strategies of transport in the process of Korean Reunification by the analysis of trials and errors in German case. This study is composed of four parts : First. Korean Peninsula is compared with Germany in terms of economical, social and infrastructure situation before and after the Unification. Secondly, Germany had very important task that is to connect West-Germany with West-Berlin located in the middle of East-Germany. Two nations had long and complicated discussions for this connection and this can show us many lessons in the consideration of the connection of Gyoungui-Line. Especially, it shows problems in the management of this connectors such as the misuse of connectors as escape routes and the conflict in the calculation of toll between two nations. Thirdly, the transport plans after the Unification in Germany are analyzed and this can provide some lessons in the long term planning : German Federal Transport Plan 1992, Transport Projects for the German Unification and other institutional supports. Finally, five strategies and five important projects are proposed for the Korean Reunification in the consideration of many lessons from German Unification.

Objectives: The objective of this study was to evaluate asphalt fumes and PAHs exposure among asphalt road paving workers. Methods: Task-based personal air samplings(n=41) were carried out in 3 asphalt road paving construction sites using PTFE (polytetrafluorethylene) filters for asphalt fume and XAD-2 with glass fiber filters for PAHs. The concentration of fumes and PAHs were showed by four different job(paver finisher operator, paving laborer(raker), macadam roller operator and tire roller operator). Results: The geometric mean(GM) concentration of asphalt fumes as benzene soluble aerosol was highest at paving laborers($42.32{\mu}g/m^3$), followed by in order, paver finisher operators($41.57{\mu}g/m^3$), macadam roller operators($31.9{\mu}g/m^3$), and tire roller operators($30.31{\mu}g/m^3$). The GM of total PAHs concentration was highest at paver finisher operators($37.5{\mu}g/m^3$), followed by in order, paving laborers($20.13{\mu}g/m^3$), tire roller operators($8.66{\mu}g/m^3$), and macadam roller operators($6.23{\mu}g/m^3$). The results of the evaluation of 16 compounds of PAHs showed that the concentrations of naphthalene, achenaphthylene, achenaphthene, pyrene, fluorene and benz (a) anthracene was higher than those of other PAHs compounds and as the carcinogenic substances, benzo(a)pyrene, and debenz(a,h) anthracene were detected. The benzo(a)pyrene equivalent concentration(BaPeq) was $2.81{\mu}g/m^3$ at paver finisher operators, $2.07{\mu}g/m^3$ at paving laborers, $0.41{\mu}g/m^3$ at tire roller operators and $0.22{\mu}g/m^3$ at macadam roller operators. Asphalt road paving workers have higher benzo(a)pyrene equivalent(BaPeq) values even though at lower total PAHs concentration than workers in steel pipe coating and tar industry. Conclusions: Asphalt road paving workers were found to have risk of carcinogen exposure due to higher Benzo(a)pyrene equivalent concentration(BaPeq) than other PAHs exposure occupations. This study confirmed the carcinogenic hazards among asphalt paving workers.

The Korean Society of Pediatric Infectious Diseases (KSPID) has participated in the task force team consisting of government authorities as well as civil medical experts and facilities to block the spread of Middle East Respiratory Syndrome in 2015. KSPID posted the "Middle East Respiratory Syndrome (MERS) Pop-up" in the homepage of The Korean Pediatric Society and The Korean Society of Pediatric Infectious Diseases. KSPID also released the "Guidelines for testing for MERS in children and adolescents" and the "Instructions for the Operation of National Safe Hospital" for children and adolescents in a timely manner. Such actions were aimed to prevent unnecessary anxieties, studies and isolation of pediatric patients with respiratory symptoms and signs caused by other common microbial etiologies as being suspected for MERS patients. This strategy relieved the doctors and parents from unnecessary fear and prevented the loss of unnecessary health care costs, and has proven to be a well-judged guideline and management protocol as evaluated after the final end of MERS outbreak. KSPID and its members should support the presence of pediatric infectious disease (PID) specialists in every medium size hospitals in Korea by developing the need for consultation fees for PID consultation in the hospital based practice and promoting the potential for cost savings related to prevention of health care associated infections and optimal prescription of antimicrobial agents. KSPID and its members need to approach and develop a communication plan to political decision makers to demonstrate and convince them of the importance of a PID specialist service.

Objectives : To develop a physical functioning instrument for older adults living in the community. Methods : A representative sample of 979 people aged 65 years or over were interviewed in-person. Of these, 199 people also completed a detailed in-hospital examination. The scale items were selected based on the frequency of endorsement, along with the item-total and inter-item correlations. The associations of the scale with their physical performance and clinical examination were analyzed to evaluate the criterion-related validity. Construct validity was assessed using factor analysis, and internal consistency through Cronbach's alpha and item-total correlations. Test-retest reliability was measured by agreement between the household survey and the repeat survey at the in-hospital examination. Results : Initially, 23 items on the level of difficulty, ranging from no difficulty to an inability to complete a task, with the specific mobility and self-care tasks were included. Those with a high frequency of endorsement and a low inter-item or item-total correlations were excluded, resulting in a 10-item Physical Functioning (PT) scale. Equal weights were given to each item and a summated score was calculated. Significant associations were found between the PF scores and the physical performance, surrey and clinical data. The scale revealed a 2-factor (mobility and self-care) structure. Cronbach's alpha was 0.92 and the item-total correlations were in the 0.63 to 0.78 range. Pearson's correlations for the test-retest ranged between 0.56 and 0.61. Conclusions : The newly developed Physical Functioning (PF) scale showed good psychometric properties in older people. Further work, however, is needed to improve its sensitivity to discriminate higher levels of functioning, in addition to assessing its predictive value in detecting changes in health.

Recent advances in computer technology have brought more dependence on software to railway systems and changed to computer systems. Hence, the reliability and safety assurance of the vital software running on the embedded railway system is going to tend toward very critical task. Accordingly, various software test and validation activities are highly recommended in the international standards related railway software. In this paper, we presented an automated analysis tool and standard for software testing coverage in railway system, and presented its result of implementation. We developed the control flow analysis tool estimating test coverage as an important quantitative item for software safety verification in railway software. Also, we proposed judgement standards due to railway S/W Safety Integrity Level(SWSIL) based on analysis of standards in any other field for utilizing developed tool widely at real railway industrial sites. This tool has more advantage of effective measuring various test coverages than other countries, so we can expect railway S/W development and testing technology of real railway industrial sites in Korea.
