  • Damage and attack size of cyber terror is growing to the national size. Not only targeting at a certain companies or individuals but number of cyber terror targeting government bodies or unspecific people is increasing. This is because compared to traditional weapon, input cost is very cheap but ripple effect and shock are much stronger, affecting not only certain groups but also each individuals. 'Anti-terror measurement for protection of nation and public safety' passed last month is one of the renowned measurement passed regardless of objection from opposition party. The opposition party went against this through filibuster for 192 hours but this finally passed National Congress due to lack of oppositions. Korean government is taking post actions after passage of anti-terror measurement. Legislation of enforcement ordinance and regulations is due by 6th of next month. This regulation will be executed from June 4th after legislation. Whenever there is any security issues such as hacking of Korea Hydro and Nuclear Power and National Intelligence Service happens, lot of attention is made to those hackers. However, social recognition or management of those hackers need lot more improvement. Especially, as market of internet of things is increasing, there is an increased anxiety on information security. But as we only rely on security solutions, this problems are keep happening. Therefore, active investment on nurturing hackers who play the role of 'spear and shield' shall be made. Government should put more efforts to allow white hackers to show their abilities. We should have a policy for supporting high-quality programs such as BoB. To make information protection industry into future growth engine, it is necessary to nurture professionals for information protection and white hackers through special programs. Politicians should make related regulations as soon as possible to remove factors that prevent swift management of cyber attack due to lack of legislation. Government should pay lot more financial investment to nurturing professional manpower than now. Protecting life and asset of nation is responsibility and duty of our government. We all should recognize that controlling cyber attack is a part of national defense.

  • Objective: The vibration device is one of the most commonly used warm-up devices not only for healthy athletes but also for healthy individuals. Therefore, this study aimed to investigate the immediate effects of local vibration on ankle plantar flexor muscle activation and peak torque in healthy adults. Design: One-group pretest-posttest design. Methods: This was a single-group study comprising a total of 36 (16 males and 20 females) participants. The average age of the 36 participants was 22.3 years. All the participants' concentric and eccentric peak torques of the gastrocnemius lateralis muscle were measured using an isokinetic device. Simultaneously, the participants' muscle activity was measured by surface electromyography. After the pre-experimental data were collected, the participants comfortably sat on the prepared chair with their hips and knees flexed to 90°. While in sitting position, local vibration was applied for 10 minutes using a 1:1 ratio intermittent pulsing mode device based on a previous study. Then, the post-experimental data were collected immediately after the local vibration by performing a similar process performed during the pre-experimental data collection. Results: The results showed a significant difference in muscle activity and eccentric peak torque (p<0.05). On the contrary, concentric peak torque values showed an insignificant difference with pre- and post-value. Conclusions: The results of this study demonstrated that local vibration can be possibly considered as one of the effective ways to increase ankle plantar flexor muscle activity and muscle performance, specifically the eccentric peak torque, in healthy adults.

  • Important crime prevention is emphasized. Depending on the type of criminal act itself, but with many material and human damage because it is a threat to the safety of civil life. The traditional police power of the police in patrolling the derailment by the diversification of the crime, globalization, organizing, specialization, and ferocious anger by far exceeds the capabilities of the police crime prevention are occurring. Civilian police crime prevention organizations in the area of the region as a base for complementary activities, and even if the purpose of commercial availability, but many organizations is the autonomous and spontaneous personality voluntary work civic life is to serve as the safety fence. But that suits the role of these organizations and social support and lack of institutional support and practical and effective crime prevention activities has not been effective. Law reform and the role of the Organization for the maintenance of redundancy, or a series of systematic effort to equip networks and take advantage of the functional and has been factory.

  • The purpose of this study is to investigate the gender division of housework in the Choson period. The gender division in the Choson period has been considered as discriminative because women had to remain indoors and were excluded in social works. But in fact the Confucian idea, which regulated the relation between women and men, emphasized the gender difference and not gender discrimination. Actually it can be seen in genre painting of Choson period that women and men worked complimentarily indoors. So this article intends to explore the possibilities of the new analysis of the traditional gender division of housework by reviewing the paintings. As the results indicate, men in the Choson period were involved in some housework, in contrast to the common idea that they maintained their authority by not participating housework. There is also some evidence that gender division benefited women to protect their own productive territory or to satisfy their needs. So it is suggested that gender division in the Choson period should be considered as a source of power as well as a disadvantage to women. Forth, the employed mens' reemployment decision was affected from their household income, expected income after retirement, pension ownership, and attitude toward retirement. From the findings, it can be concluded that the employed mens' age, economic status, and attitude toward retirement played a important role in the process of retirement and reemployment decision making.

  • Fine dust has become a significant social problem. Diesel engines are used as the main propulsion power source in ships. This study introduces a diesel particulate filter (DPF) that is used as an exhaust after-treatment system for diesel engines to reduce particulate matter known as diesel fine dust. Two materials are used for the DPF: Cordierite and silicon carbide (SiC). In this study, to improve the physical properties of the binder used in the SiC DPF, cordialite was used instead of the SiC-based materials used as the conventional binder to evaluate the thermal durability against high-temperature deformation through the change of the coefficient of thermal expansion. In addition, the physical properties of the silica sol, as a main component of the base coating solution for determining the bond between the binder and the segment, were confirmed. Based on this, the change effect of the binder physical properties was confirmed through experiments by either adding a silane coupling agent or SiC to increase the reactivity of the silica sol.

  • Objectives : The purpose of this study was to investigate the relationship between masseter and cervical muscle activity and temporomandibular disorder in female office workers. Methods : Experimental group of 24 healthy subjects complained of temporomandibular joint related to computer use which lasted more than 3 months in the past year and was present in the past 7 days as well as on the day of test. Control group of 20 healthy subjects had no complaints of minimal discomfort on the day of test, and had no discomfort in the past 7 days. If they had reported discomfort in the past 12 months, it was of a short duration(<3 months) and resolved at least 3 months prior to participation. Outcomes were assessed by meridian-electromyography(MEMG), whole spin x-ray, mandibular function impairment questionnaire(MFIQ), neck disability index(NDI), visual analog scale(VAS), Beck depression inventory(BDI), stress reaction inventory(SRI) and Holmes & Rahe social readjustment rating scale(SRRS). Results : The contraction power of masseter muscle, upper trapezius, sternocleido-mastoid muscle and erector spinae by MEMG was significantly higher in the experimental group. The muscle fatigue of masseter muscle and sternodeido-mastoid muscle by MEMG was significantly higher in the experimental group. SRI was significantly higher in experimental group. There was no significant difference between two groups in the Jackson's angle, Cobb's method and cranio-cervical posture. Conclusions : The results suggest that temporomandibular disorder related mental stress but physical stress does not change cervical structure significantly.

  • Recent globalization and de-industrialization have caused intensive competition among places; hence, cities worldwide are pursuing regeneration and enhanced competitiveness through cultural strategies. Focusing on the cultural strategies of local cities in Japan, this paper reveals that the concept of "being-a-region" is key to cultural strategies, and explores what logic is inherent in such regional developments. Since the period of rapid economic growth, Japanese local cities have played the role of "Furusato(home) for Japanese." With the recent decentralization, "being-a-region" is now emerging as a powerful discourse for the cultural strategies of local cities. This idea of "being-a-region" can be largely defined as a region's special character or even an existential sense of place, but in fact it is political relationships among agencies that define the region. "Being a region" in Japan appears to extend to "being a nation." Thus, it would be necessary to focus on the power relationships that surround the concept of "being a region" when we deal with the meaning of region in relationships to cultural strategies of local cities.

  • Recently seismic fragility analysis method has been widely used for the seismic probabilistic risk assessment of infrastructures such as nuclear power plants, buildings and bridges because of its probabilistic characteristics. Furthermore, this technique has been applied to large-scale social systems consisted of each infrastructures by combing GIS. In this paper, the applicability of this technique to domestic infrastructural systems was studied. The transportation network was selected as one of these domestic infrastructural systems. Example studies were peformed about Changwon city. Nonlinear time history analysis, with a maximal likelihood approach were conducted to establish the fragility curves of each infrastrucures (bridges). GIS analysis was also applied to the analysis of whole infrastructural systems. The results show that it is very useful to predict seismic probabilistic risk assessment of this domestic transportation network. However, it also shows that further studies such as more suitable damage criterion to domestic structure and precise nonlinear analysis techniques should be developed to predict more precise results.

  • The earlier animations aimed to express the characters realistically by making the illustrations look like moving and alive. Since then, animations have been influenced by development of media technology, men's changed mentality and evolvement of diverse social phenomena, while influencing them, too. Among them, the computer which emerged first in 1946 has sewed to more diversify the tools for realistic expressions of animations, and further, enhance the intellectual power of expression media only to expand the new visual expressions and thereby, usher in a multi-media video information environment. Moreover, this technology or computer has urged every discipline to disintegrate its conventional order for the post-modernism characterized by polysemous, diversified, obscure and sometimes, mutually contradicting elements, and as a result, animations had to find a new breakthrough in the conventional reality (cognitive and reflective reality). Thus, animations have been real enough to be perceived impromptu and emotionally, faster than the logical cognitive process beyond the simple technological barrier or the screen image processing. With such backgrounds in mind and by defining such a reality as 'sensuous reality', this study aimed to apply Gilles Deleuze's, reality of space to animation films and interpret it.
