  • Tewoo refers to a traditional group of Jeju's rafts for fishing in the rough Jeju sea in the past. We propose a mobile game called 'TewooGwang' based on a fishing boat called 'Tewoo', which has a scenario of conquering the Jeju sea using unique characters symbolizing the Jeju's ocean culture. This game is a new game, which uses a character of the fishing boat 'Tewoo', the background based on only Jeju's features, the high portability of PDA, and multimedia technology. It is different from simple sports games and has various game scenarios according to interactions of Tewoo character. The structure of this game represents a storytelling, which integrates Jeju culture into cyberspace. There are stories in this game and users also can make their own stories. Thus, this game enables hi-directional communications. It presents an imaginative space, which can induce a conflictive structure made by each user, and spatial provability. Many young Jeju tourists will enjoy it because this game provides a dynamic story. Furthermore, we can contribute to serving the value-added Jeju culture of being upgraded one step through this Jeju culture based game.

  • This study aims at providing useful fundamental information to re-establish the theories of modern fashion by examining the origination and genealogy of street style. The street styles focusing on caucasoid have a variety of genealogies such as western type, beat, teddy boy, hippie, skinhead, punk, neuron-mantic, indie kid, riot grrrl, grunge and techno cyber punk. In the same period, on the contrary, the streets styles focusing on negroid are zootie, hipster, modernist, rude boy, two-tone, rastafarian, funky, B-boy, fly girl, raggamuffine, bhangra, and acid jazz, which are seen as the culture of the large cities formed along Atlantic Ocean and Caribbean sea like England, America and Jamaica. These have root as the main fashion in western society. Ironically, most of the subculture concentrated on the whites were racists. Because of such a reason, the street styles have been formed as resistance culture that was unable to sympathize with their society and characteristics by distinguishing the whites and the colored people. Zootie or hipster that is one of the street fashion styles was formed in the 1940-50s, while the colored people who lived in the west Indies migrated to England or America. As a minimal modernist style called Ivy look in US, in that time, anti-culture formed by teenagers in whitey, teddy boy and mods fashion can be strictly different from the zootie and hipster. The colored people's street styles of the 1960s developed into aggressive and hard forms from the rude boy and two-tone while their resistance toward the whites was stronger. The rastafarian style researched the peak as the colored people's traditional ethnic characteristics or resistance intention for their freedom in the 1970s. In that time, The colored people's street styles of the 1960s developed into aggressive and hard forms from the rude boy and two-tone while their resistance toward the whites was stronger. The rastafarian style researched the peak as the colored people's traditional ethnic characteristics or resistance intention for their freedom in the 1970s. In that time, the street styles of the whites were mostly the skinhead or hippie. Most of them were racists toward the colored people. The punk type on shown on the whites focused on luxury and exaggerative costume. On the contrary, the funky style of the colored people focused on aggressive nihilism and form. With B-boy, fly girl, reggae, rap music, and break dancing in the 1980s, the subculture gradually told on the high fashion as well as the culture between the whites and the colored people. From such aspects, the colored people tried to maintain their unique traditional characteristics. However, their individual values surged by the coming young generation excluded the colored people's characteristic street styles. Focusing on gender, violence and private success among their major concerns, the raga muffin style that represents multi-races and multi-cultures was formed. The jazz style in the 1990s showed cold post-modernistic eclecticism different from that of the 1940s-50s. Simultaneously, the various classes appeared their street styles by emphasizing on each personality. Now that we are living in multi-cultural society, a human race or nationalism concept is getting obscurer. There is no obvious boundary line in the differences between human race and its fashion.

  • The algicidal effects of marine bacteria were investigated and a strain, which had the strongest algicidal activity against the harmful dinoflagellate, Cochiodinim polykrikoides was selected. The bacterium was isolated in seawater during the period of blooming of C. polykrikoides in Masan Bay. This algicidal bacterium was identified as Micrococcus sp. LG-5 by means of morphological and biochemical tests. The optimal culture conditions of Micrococcus sp, LG-5 were $25^{\circ}C,\;pH 7.0\;and\;3.0{\%}$ NaCl concentration. The algicidal activity of Micrococcus sp. LG-5 was significantly increased to maximum value in the late of logarithmic phase of cell cuture. In addition, the culture filtrate ($pore size,\;0.1{\mu}m$) of Microcoocus sp. LG-5 showed strong algicidal effects. The cell numbers of C. polykikoides were decreased from $1.2{\times}10^4 cells/ml\;to\;less\;than\;2{\times}10^3\;cells/ml$ within 3, 6, 30 hours at the concentrations of culture filtrate $10{\%},\;5{\%}\;and\;1{\%}$, respectively. These results indicated that the algicidal effect was mediated by certain substances released from Microooccus sp. LG-5.

  • Neurokinin B (NKB) and neurokinin B related peptide (NKBRP) belong to tachykinin peptide family. They act as a neurotransmitter and/or neuromodulator. Mutation of NKB and/or its cognate receptor, NK3R resulted in hypogonadotropic hypogonadism in mammals, implying a strong involvement of NKB/NK3R system in controlling mammalian reproduction. Teleosts possess NKBRP as well as NKB, but their roles in fish reproduction need to be clarified. In this study, NKB and NKBRP coding gene (tac3) was cloned from Nile tilapia and sequenced. Based on the sequence, Nile tilapia NKB and NKBRP peptide were synthesized and their biological potencies were tested in vitro pituitary culture. The synthetic NKBRP showed direct inhibitory effect on the expression of GTH subunits at the pituitary level. This inhibitory effect was confirmed in vivo by means of intraperitoneal (ip) injection of synthetic NKB and NKBRP to mature female tilapia (20 pmol/g body weight [BW]). Both NKB and NKBRP had no effect on the plasma level of sex steroids, E2 and 11-KT. However, NKBRP caused declines of expression level of GnRH I, Kiss2 and tac3 mRNAs in the brain while NKB seemed to have no distinct effect. These results indicate some inhibitory roles of NKBRP in reproduction of mature female Nile tilapia, although their exact functions are not clear at the moment.

  • The purpose of this study was to investigate the job stress factors of aircraft composite material part manufacturing workers using survey based on 'Job stress factors evaluation tool for Koreans' that was developed by KOSHA in 2003. Two hundred and fifty workers participated in this study, and among them 204 responses were analyzed for this study due to the unreliability and insincerity of responses. The eight job stress factors which are physical environment, job autonomy, job insecurity, organizational system, workplace culture, unfair compensation, relationship conflict, and job requirement were analyzed. The results showed that the stress level of the six job stress factors which are physical environment, job autonomy, job insecurity, organizational system, workplace culture, unfair compensation was relatively higher than that of other industry workers. Generally, all eight job stress factors showed higher stress with temporary workers than with permanent workers, and especially job autonomy, job insecurity, organizational system, and unfair compensation factors showed statistically significant differences (p<0.05). Since the temporary workers are insecure with their job, weak position in organization, having little self-control for the job and lower pay level than that of permanent workers though the job is as same as permanent workers', the stress level of above job stress factors would be much higher than that of the other factors. The group of unsatisfactory with workplace showed higher job stress than group of satisfactory with workplace in all job stress factors, as expected, at the statistically significance level (p<0.05). From the results of this study, the work loss due to the job stress could be prevented, and accurate stress factors could be removed at the workplace. Also the job stress management program can be implemented to improve the work efficiency and the workers' quality of life.

  • The phenology of Campylaephora hypnaeoides J. Agardh and optimal conditions for carpospore release, growth and reproduction were examined in the field and in the laboratory from January to December 2007. In the field population of C. hypnaeoides, approximately 50% of the plants were vegetative during the study period. Additionally, the percentages of carposporophytes and tetrasporophytes were maximal in April (37%) and June (57%), respectively. Maximum growth in plant length, dry weight, and hook number coincided with the tetrasporophyte reproductive peak in the field. In culture, carpospore release, sporeling growth and reproduction were affected by environmental factors such as daylength, temperature, and salinity. The liberation of carpospores was maximum under continuous light and at a combination of $15^{\circ}C$ and $10\;{\mu}mol$ photons $m^{-2}\;s^{-1}$. Maximum growth of tetrasporophyte sporelings occurred at a combination of $20\;{\mu}mol$ photons $m^{-2}\;s^{-1}$ of constant light and $25^{\circ}C$. However, the growth of gametophyte sporelings was maximal under $40\;{\mu}mol$ photons $m^{-2}\;s^{-1}$ of constant light and in a combination of $20^{\circ}C$ and 35 psu. The tetrasporophyte sporelings were grew faster than gametophytes, indicating that gametophyte- and tetrasporophyte-sporelings have different physiological responses to irradiance and temperature. Tetrasporangial branches and cystocarps of C. hypnaeoides were produced from carpospores and tetraspores within 1 month, and they were stimulated at high temperature and irradiance levels. In conclusion, C. hypnaeoides should be seeded using carpospores during early winter (November-December) because cystocarps are easily identified by fishermen, and tetrasporophytes grow faster than gametophytes.

  • Statistical experimental designs; involving (i) a fractional factorial design (FFD) and (ii) a central composite design (CCD) were applied to optimize the culture medium constituents for production of a unique antifreeze protein by the Antartic micro algae Chaetoceros neogracile. The results of the FFD suggested that NaCl, KCl, $MgCl_2$, and ${Na}_{2}{SiO}_{3}$ were significant variables that highly influenced the growth rate and biomass production. The optimum culture medium for the production of an antifreeze protein from C. neogracile was found to be Kalle's artificial seawater, pH of $7.0{\pm}0.5$, consisting of 28.566 g/l of NaCl, 3.887 g/l of $MgCl_2$, 1.787 g/l of $MgSO_4$, 1.308 g/l of $CaSO_4$, 0.832 g/l of ${K_2}{SO_4}$, 0.124 g/l of $CaCO_3$, 0.103 g/l of KBr, 0.0288 g/l of $SrSO_4$, and 0.0282 g/l of ${H_3}{BO_3}$. The antifreeze activity significantly increased after cells were treated with cold shock (at $-5^{\circ}C$) for 14 h. To the best of our knowledge, this is the first report demonstrating an antifreeze-like protein of C. neogracile.

  • This thesis will show the preparation of politic alternative plan about reaction through studying the domestic and overseas research trend and theories about online games analyzing the related problems. Online games have been already placed as the major culture trend in our society and produced the economic wealth as the major theme of 'Korean trend hot wind', including improvement of our foreign confidence. And the investments in online games and related industry are expected to be great Blue Ocean to us to have relatively deficient endowed resources. But with these beneficial effects, many unexpected reactions have happened and often published by medias, and they will be expected to be serious. So, it is to establish the united solution system of disputes related to online games which are spread in each law. Through this, we must draw prevention effects and use that as the evidence of rational judgements. And we must make the base to give online games the opportunity of upgrading to national strategic industry and try to conduct the research in various fields between academic organizations.

  • We investigated ethanol production from glycerol after screening of the yeast Pachysolen tannophilus ATCC 32691. For yeast to produce ethanol form glycerol, it is important that aeration is finely controlled. Therefore, we attempted to produce ethanol using a surface-aerated fermentor. When 880 ml of YPG medium (1% yeast extract, 2% peptone, 2% glycerol) was used to produce ethanol, the optimal aeration conditions for ethanol production were a surface aeration rate and agitation speed of 500 ml/min and 300 rpm, respectively. In a fed-batch culture, the maximum ethanol production and the maximum ethanol yield from glycerol (Ye/g) was 5.74 g/l and 0.166, respectively, after 90 hr using the surface-aerated fermentor.

  • COVID-19 pandemic brings attentions to the nonmilitary and transnational non-traditonal security threats, as the scales of such damage by these threats are beyond expectation. The Republic of Korea Army tries to forecast non-traditional security threat which may be occurred in Korean peninsula by using collective intelligence platform. In coming years, climate change, social changes and technology development caused by the 4th industrial revolution will diversify non-traditional security threat. Considering urbanization, internet distribution rate, and geopolitical location where atmosphere from continent and ocean meet, Korea would may face the most lethal ones compared to those of other countries may face. Therefore, to predict such threats in pangovernment scale using collective intelligence platforms which embrace civil, public, military, industry, academy and research center is the most important than anything.
