The spreading Cocuoainim polykikoides bloom in the southern coastal waters of Korea was simulated using numerical model including the physical processes of water flow and the chemical processes of increasing cell of C. polykikoides by uptake of dissolved nutrients. The circulation of sea water was simulated by two dimensional tide model reflecting the main four tidal components of $M_2,\;S_2,\;K_1,\;O_1$, and permanent current was driven by inflow/outflow across open boundaries. According to the result of model which tidal and permanent current were reflected simultaneously, eastward flows entering the southern waters from the western waters of Korea are dominant but westward flows are weak relatively. These result suggest that it is difficult for initial C. polykikoides bloom generated in the coastal waters of Goheung to move to the western coast of Korea through Jeju Strait. For spreading model of C. poiyhikoides, the range of generating distribution and the generating time of C. polykikoides bloom in coastal area are similar to those of observation data in the field. Wind is the most important factor in moving and distribution of red tide. Permanent current flowing eastward is also considered to be important factor and tidal current was a little influenced.

Pauline Hopkins's Of One Blood; Or, the Hidden Self was published in the Colored American Magazine during 1902-03. As a literary experimentalist and a political protester, Hopkins uses her fiction as a medium to overcome and ameliorate the violently racialized surroundings of the turn-of-the-century America. Having been faced with racist rhetorics and theories growing on biological differences between races, Hopkins must have felt an overwhelming urgency to challenge the heritage of slavery in American history. In order to speak out her political agenda in such a milieu, she needed a new setting as well as new narrative materials for the new era. She had to move the setting from America to Africa, the ancient utopian Ethiopia; her interest in the ancient African civilization reflects both a popular African-American vision of Africa and the movement of "black nationalism" of the time. She also needed materials from nineteenthcentury sciences, the newly evolving theories of psychology and mysticism (spiritualism/mesmerism), to explore the meaning of "the hidden self" which unfolds the complex nature of Hopkin's position on race, "blood," and African-American racial subjectivity. Hopkins in the novel explores not the color line but the bloodline. Tracing the horrific legacy of incest in the history of slavery, she attempts to redefine the true racial identity of African-Americans in America and to reconstruct their past, both family and race history. At the very center of her major tropes in the novel-such as "of one blood," "the hidden self," and incest-exists female body. Black female body, though it represents the violent site of sexual body (rape and incest) in slavery, ultimately becomes a vehicle to convey and preserve the truth of racial memory/past/history for African-Americans. As a conveyor of the past, black women not just connect the past and the present but also reawaken AfricanAmericans with the legacy of the African 'pure' bloodline. Hopkins's vision here necessitates the reevaluation of black women's role in family and history, heralding the 20th-century black feminine writing. With the major tropes, Hopkins clearly suggests that the blood of (African-)Americans is unrecognizably intermixed. Although the novel ends with ambivalence and without resolution on what Africa signifies, those tropes certainly offer her a vehicle for criticizing as well as for challenging the racial reality of America.

Korea Polar Research Institute (KOPRI) has successfully installed two autonomous very broadband three-component seismic stations at the King George Island (KGI), Antarctica, during the 24th KOPRI Antarctic Summer Expedition (2010 ~ 2011). The seismic observation system is originally designed by the Incorporated Research Institutions for Seismology Program for Array Seismic Studies of the Continental Lithosphere Instrument Center, which is fully compatible with the Polar Earth Observing Network seismic system. The installation is to achieve the following major goals: 1. Monitoring local earthquakes and icequakes in and around the KGI, 2. Validating the robustness of seismic system operation under harsh environment. For further intensive studies, we plan to move and install them adding a couple more stations at ice shelf system, e.g., Larsen Ice Shelf System, Antarctica, in 2013 to figure out ice dynamics and physical interaction between lithosphere and cryosphere. In this article, we evaluate seismic station performance and characteristics by examining ambient noise, and provide operational system information such as frequency response and State-Of-Health information.

The purpose of this research is to study how service recovery activities influence customers' commodity churning in the media telecommunication industry(CATV industry). Put it differently, we tried to identify this change of commodity churning rates by the stages of service failures, by which we intend to emphasize the importance of service recoveries. Korean media telecommunication market has already been saturated; customers tend to move to bigger major companies with better customer care increasingly. As once customers gone never returns, CRM functions are being reinforced over the time. We were able to have the following results. First, turning rates, for those experienced service failure, who were dissatisfied with service recovery activities are 2~5 times (monthly average turning rates are 1.3%) higher than those satisfied. Secondly, active service recovery activities at the customer's service request after experiencing service failure lowered churning rates significantly. The most effective timing is service recovery activities pre-recovery stage. Thirdly, reward activities after service recovery activities at the immediate recovery stage is more effective than service recovery at the arranged recovery schedule and reward activities after customer's expressing churning intension. The implications of this study are that firms should engage in service recovery activities at the time of identifying service failures, prior to customer's expressing churning intention, which means relatively lower ROI for the service recovery activities than the times of customers' expressing churning intention.

Since being designated as an important Intangible Cultural Property, Yeongsanjae has become recognized as a unique representation of Buddhist rituals in Korea. Following vigorous research in recent years, however, Suryukjae(水陸齋) was found to have been performed for a longer period and on a larger scale than Yeongsanjae, and under state leadership. This allowed researchers to move beyond the previous perspective that Yeongsanjae(靈山齋) lay at the center of many rituals. This study aims first to examine the origin and development of Yeongsanjae in Korea based on the literature, and then to discuss the meaning it holds today. Yeongsanjae was recorded as a ritual in Jineongwongong -published in 1496 during the early Joseon Dynasty- and also appeared in Yeongsandaehoejakbeopjeolcha -published in 1634(the 12th year of Injo's reign) in the mid-Joseon Dynasty and it was called Yeongsandaehoejakbeopjeolcha. It continued into the late Joseon Dynasty and it was called Yeongsanjakbeop or Yeongsandaehoejakbeop in the Ojongbeomeum collections(1661), CheonjimyeongyangSuryukjaeuiBeomeumsanbo collections(1721), and Jakbeobguigam(1826). In modern times, it has been called Yeongsanje in newspaper articles of TongnipSinmun (The Independent) and Yeongsanjae in Seokmunuibeom(1935). Nevertheless, the difference between the early Joseon Dynasty and subsequent periods is whether mourning of the spirit(唱魂) is added. In this regard, Yeongsanhoe in the early Joseon Dynasty mainly concerned Buddhist teachings realized through rituals such as sermon scenes of the Buddha. On the other hand, it was combined with Buddhist masses for the dead(追薦) from the mid-Joseon Dynasty and performed alongside with Buddhist teachings and prayers for the dead. Taking into account the seven-day Suryukjae, however, Yeongsanjae was performed daily during the day and mainly dealt with Buddhist teachings, while Buddhist masses for the dead were included when Yeongsanjae was performed independently.

In this study, the fluid flow and heat transfer characteristics within sandwich panels are investigated using computational fluid dynamics. Within the sandwich panels having periodic cellular cores, air can freely move inside the core section so that the structure is able to perform multi-functional roles such as simultaneous load bearing and heat dissipation. Thus, there needs to examine the thermal and flow analysis with respect to design variables and various conditions. In this regard, ANSYS Fluent was utilized to explore the flow and heat transfer within the pyramidal truss sandwich structures by varying the truss angle and inlet velocity. Without the entry effect in the first unitcell, the constant rate of pressure and the constant rate of Nusselt number was observed. As a result, it was demonstrated that Nusselt number increases and friction factor decreases as the inlet velocity increases. Moreover, the rate of Nusselt number and friction factor was appreciable in the range of V=1-5m/s due to the transition from laminar to turbulent flow. Regarding the effect of design variable, the variation of truss angle did not significantly influence the characteristics.

The purpose of this study is to examine the necessity of providing new perspectives by conveying the various psychological changes and realities experienced by victims of incest sexual violence after the incident, And it is meaningful to understand and record it through. The results of the analysis through the phenomenological methodology are as follows: First, participants were disturbed by the emotional neglect of their parents and forced violence, threats, and silence by their family members, resulting in disbelief in interpersonal relationships and low self-esteem and suffered constant difficulties in daily life. Second, the suffering and aftereffects of sexual violence experienced the conflict of roles by repeating the real maladjustment and social activity avoidance as the fear of being informed about the event, the negative thought about oneself, and the difficulty of interpersonal relationship. Third, the aftereffects of incest sexual violence in childhood·adolescence were found to be extreme with regard to PTSD. The PTSD experience has become a factor that forces participants to rely on substances, such as psychiatric medications and alcohol, and further avoids external activities with hallucinations and delusions. Fourth, the change through the adaptation process is a new perspective on life, facing and separating the events. During the adaptation program, they tried to express their words and feelings that they could not express because of the past hurts, to set goals for living their life, and to move forward. The experience of overcoming reality has enhanced participants' confidence in self-esteem, self-efficacy, and healthy self-control ability. In this study, it is meaningful to suggest a model in which the incest sexual violence trauma is reexperienced through the new daily crisis and the new adaptation process is repeated for each process.

Background: Since people move through microenvironments rather than staying in one place, they may be exposed to both indoor and outdoor PM_2.5 concentrations. Objectives: The aim of this study was to assess the exposure level of each sub-population group and evaluate the contribution rate of the major microenvironments. Methods: Exposure scenarios for sub-population groups were constructed on the basis of a 2019 Time-Use survey and the previous literature. A total of five population groups were classified and researchers wearing MicroPEM simulated monitoring PM_2.5 exposure concentrations in real-time over three days. The exposure contribution for each microenvironment were evaluated by multiplying the inhalation rate and the PM_2.5 exposure concentration levels. Results: Mean PM_2.5 concentrations were 33.0 ㎍/m³ and 22.5 ㎍/m³ in Guro-gu and Wonju, respectively. When the exposure was calculated considering each inhalation rate and concentration, the home showed the highest exposure contribution rate for PM_2.5. As for preschool children, it was 90.8% in Guro-gu, 94.1% in Wonju. For students it was 65.3% and 67.3%. For housewives it was 98.2% and 95.8%, and 59.5% and 91.7% for office workers. Both regions had higher exposure to PM_2.5 among the elderly compared to other populations, and their PM_2.5 exposure contribution rates were 98.3% and 94.1% at home for Guro-gu and Wonju, respectively. Conclusions: The exposure contribution rate could be dependent on time spent in microenvironments. Notably, the contribution rate of exposure to PM_2.5 at home was the highest because most people spend the longest time at home. Therefore, microenvironments such as home with a higher contribution rate of exposure to PM_2.5 could be managed to upgrade public health.

This study was conducted with the elderly who used a senior welfare center to help their health improvement. After the status of body composition, senior fitness, life habits, and nutrition levels in the elderly were investigated, a wellness health improvement program was conducted for 12 weeks. Effects before and after the program were examined. The following conclusions were drawn. 1. For the changes of body composition by age associated with sex, while elderly men had a significant difference in BMI, elderly women had a significant difference in B.M.I and body fat percentage. 2. For the changes of senior fitness by age associated with sex, while elderly men had a significant difference in lower body muscle, upper body muscle, upper body flexibility, and transformed general endurance, elderly women had a significant difference in lower body muscle and upper body muscle. 3. For the changes of life habits and nutrition levels by age associated with sex, while elderly men had a significant difference in diet habits and exercise habits, elderly women had a significant difference in exercise habits, stress relief habits, and total nutrition level. Based on the findings, the elderly's participation in the wellness improvement program can enhance lower body muscle which is a risk factor of daily activities and fall and increase upper body muscle which is good to carry and move everyday objects. In addition, it may play a positive role in improving diet habits and changing stress relief and exercise habits, resulting in better health and quality of life of the elderly.

The purpose of this study is to examine the direction of the elderly theatre by analyzing an example of the elderly theatre program which is attempted in a way of the welfare of senior citizens in terms of cultural support. To this end, the 'Hoechun Circus' composed of elderly women in Dangjin, South Chungcheong Province, was investigated and analyzed. Research methods uses a case study, performance theory, and peer review strategies to increase the validity of the study. The results of the study are as follows: Firstly, the elderly women intended to communicate with children and adolescents through performance; Secondly, they wanted to communicate with other physically uncomfortable elderly people; Thirdly, they also attempted to communicate with young or middle-aged as well as all residents; Fourthly, they experienced a new genre of theatre to identify themselves in a different ways and enhance their sense of accomplishment and spent their old age pleasantly and informally. Based on these findings, the following suggestions were made. First, we should expand the theatre programs of senior citizens which benchmark the 'Hoechun Circus'. Second, various cases of elderly theater should be studied and policy research to support such elderly theatre is necessary. Besides, educational courses to train elderly theatre experts should also be developed. Third, it should also seek ways for the program to move beyond regional limits and interact with organizations at home and abroad. Fourth, there is room to explore new ways in the field of theater therapy, and the development of sociodrama or psychodrama programs can be an alternative.
