The objective of this study was to determine the effects of self-differentiation and ego-resilience on service maladjustment behaviors of Social Service Agent. To achieve this, we chose these research questions. To verify these research questions, data were collected by distributing 470 questionnaires to Social Service Agent serving in service organizations located in Seoul. Four hundred twenty-seven surveys were used for statistical analysis. The results of this study are as follows: First, Social Service Agents were shown to generally adjust well to service, as self-differentiation and ego-resilience were slightly higher than the median, while service maladjustment behavior was slightly lower than the median. Second, when the effects of sociodemographic characteristics, self-differentiation and ego-resilience on service maladjustment behavior were studied, all values of sociodemographic characteristics, self-differentiation and ego-resilience affected all lower factors of service maladjustment behavior with significance. For social withdrawal, the effectiveness of interpersonal relations, optimistic attitude, and the degree of family regression had a negative correlation, and emotional divorce, education level, and term of service had a positive correlation. The degree of family regression, anger management, and cognitive function vs. emotional function had a negative correlation with hyperactivity while self unity had a positive one. Family regression, cognitive function vs. emotional function, anger management, and family's economic level negatively correlated with aggression. Family regression, optimistic attitude, cognitive function vs. emotional function, family's economic level and term of service had a negative correlation with obsession and compulsion.

This study conducted a screening-level ecological risk assessment for heavy metals in dredged sediment for recycling in terrestrial environment. Toxicological information of six heavy metals (i.e., Cu, Zn, Cd, Pb, Cr, and Ni) was collected from ECOTOX of US Environmental Protection Agency, and screened and qualified for the use in the screening-level ecological risk assessment. According to the number of terrestrial ecological receptors for which toxicological information is available, PNEC (Predicted No Effect Concentration) of each heavy metal was derived using either stochastic approach (for Cu, Zn, and Cd), or deterministic approach (for Pb, Cr, and Ni). Hazard quotients of the six heavy metals were derived for a field-collected dredged sediment using the PNEC derived and the PEC (Predicted Environmental Concentration) determined for the dredged sediment. The HQs of Cu, Zn, Cr, Pb and Ni were higher than unity indicating a possibility of ecological risk of the five heavy metals when the dredged sediment is applied in terrestrial environment. Accordingly, remediation processes or a higher-level ecological risk assessment would be needed for the recycling of the material.

It is growing a necessity of consideration and management to the relevant policies for the elderly Patriots and Veterans systematically in order to increase the life-supported services since the rapid growth of the aging society. It is difficult to ensure the outcome of cost-effectiveness about the policies because of the residual welfare view and the limitation of the government budget in terms of the traditional Bohun(Korean independent movement activists, veterans and sacrificed advocators for democratization) service, though. In addition, it is not realized the individual activity and daily life-supported services yet to the elderly Patriots & Veterans since the concentration of security income and medical care. Accordingly, it is proper to quest a new Bohun policy from the traditional residual welfare view to universal or ubiquitous welfare service, which will enable them to get the various care service benefit in terms of cost-effectiveness. In this vein, the study is trying to figure out the alternative supply mechanism in-home care service to the elderly Patriots and Veterans; especially, the study emphasizes on the linkage between the regional social welfare service system and Bohun welfare service system.

3Phase PWM rectifier has become increasingly popular due to its capability of nearly sinusoidal waveform of the input current, and nearly unity power factor operation as a AC/DC rectifier of high capacity telecommunication power supply system. Generally, PI controller is used as a voltage controller of PWM rectifier and voltage controller must be designed to have low overshoot in transient state to get a reliability and stable operation. However, in the application of telecommunication in which load condition is varied very fast, the voltage controller must have a large bandwidth to reduce output voltage variation. The PI controller with large bandwidth arouse the excessive overshoot of the output voltage, and this large output voltage variation degrades the reliability of communication power of the three-phase PWM Rectifier. In this paper, new IP voltage controller for 3 phase PWM rectifier is proposed which has relatively low transient output voltage variation. The improved output characteristics of the transient state voltage responses of the starting and at load changes of the proposed voltage controller are proved by simulations and experiments.

The pharmacological profile of KR-31081, a nonpeptide $AT_1$ selective angiotensin receptor antagonist, was investigated by receptor binding studies, functional in vitro assays with rabbit aorta. KR-31081 inhibited the specific binding of $[^{125}I]\;[Sar^1,\;Ile^8]$-angiotensin II to human recombinant $AT_1$ receptor with an 8.6-fold greater potency than losartan ($IC_{50}$: 1.43 and 12.3 nM, respectively), but it did not inhibit the binding of [$^{125}I$] CGP 42112A to human recombinant $AT_2$ receptor ($IC_{50}$: higher than $10{\mu}M$ for both). The Hill coefficient for the competition curve of KR-31081 against $AT_1$ receptor was not significantly different from unity (0.99). Scatchard analysis showed that KR-31081 interacted with human recombinant $AT_1$ receptor in a competitive manner, as with losartan. In functional studies with rabbit aorta, KR-31081 competitively inhibited the contractile response to angiotensin II ($pK_B$ values: 8.66) with 20-70% decrease in the maximum contractile responses, unlike losartan that showed competitive antagonism without any change in the maximum contractile responses to angiotensin II ($pA_2$ values: 7.59). These results suggest that KR-31081 is a highly potent $AT_1$ selective angiotensin II receptor antagonist with a mode of insurmountable antagonism to be developed as the exploratory potential of this compound.

The housing market is now difficult because of excess of the increase rate of housing and long-term recession but high-rise mixed-use buildings can mix residential facilities with various demand facilities focusing and they have the advantages to secure open space and excellent view by high-rise apartment. But there are problems by hindrance of skyline formation and height of buildings. Therefore, the purpose of this study is to suggest the height standard and the slenderness ratio to location types of Mixed-use Residential Tall buildings. For the method of the study, term arrangement through literature search and the precedent research survey were first done, the level of urban design and the details related to the height of buildings were done as the case research focusing on the 16 cases in Seoul. The following results were drawn by suggesting the height standard and the slenderness ratio by location type based on them. First, the height of mixed-use building by location type in the level of urban design gets higher starting from the secondary center of the city and can be suggested as from less than 150m to more than 200m. Second, the slenderness ratio shall be planned as more than 1:3 because the area of the ground level of mixed-use building is large unlike Mixed-use Residential Tall buildings and visual passage shall be placed so that unity of openness and group formation will be planned. Third, for the height related to Mixed-use Residential Tall buildings, amendment of the special architectural district system and the special law related to super high-rise buildings shall be enacted.

This study is to exhibit the iconographic narrative and visual culture of ancient Chinese art. The focus of the study is the composite integration of literature and graphic forms, in particular the heterochronous expression of different scenarios of scenes occurring in different time periods in pictures of ancient art. The unity of their origins with picture narration and comic art creation is the fusion of our modern times. The ancient Chinese understanding of visual art includes the traditional style of images and their symbolic meanings. Among artistic narrative expression, imagery contemplation and visual presentation have significance. Artistic thinking is inseparable from visual articulation. It is a rational thought process through creative language interpretation in visual media of imagery narratives. The characteristics of ancient imagery thinking and the way of presenting sequential incidents in the form pictures is a creative space of time. This is the spatial thinking of modern comic art, which is demonstrated through acceptance in artistic styles. Image narration needs new forms and media styles, including integrating with cultural values as aesthetic communication is necessary.

Pharmacokinetics of DWP401, a recombinant human epidermal growth factor (rhEGF), was studied using radioimmunoassay (RIA) and $^{125}I$-DWP401 in rats. When DWP401 was adm inistered i.v. at doses of 50 and 500 mcg/kg, the plasma DWP401 disappeared biiexponentially with terminal half life of 4.7 and 92.8 min. The $C_{max}$ and $T_{max}$ after s.c. administration of ti at doses of 50 and 500 ${\mu}g$/kg were determined to be 23.6 and 17.5 ng/ml at 50 ${\mu}g$/kg, and 261.4 ng/ml and 36.8 min, respectively. Both the total urinary and biliary recoveries of intact DWP401 2343 very low (<0.4%), probably due to its extensive degradation in the body. the concentration ratio of DWP401 between the organ and plasma decreased especially in the liver and kidney as the dose and time after the dose increased. For example, the liver/plasma and kidney/plasma concentration ratio of DWP401 at 2.5 min after i.v. doses of 50 ${\mu}g$/kg were comparable and much larger than unity. But, the ratio at 2.5 min after i.v. doses of 500${\mu}g$/kg was much larger in the kidney that in than in the liver. These results suggest that the systemic administration of DWP401 might be subject to rapid and extensive clearance from circulation within several hour after main distrbution to liver and kidney.

Recently there are growing needs and demand to enhance 'Unity of knowledge' as the concept of "Creating new value through integration and convergence" is developing rapidly in many different areas in the society. This also has significant implication to education. Especially, it requires paradigm shift in terms of required capabilities and qualifications for the students with science major. To accommodate this trend, Natural Sciences and Engineering's College has been increasing convergence education which focus on cultivating creative and cooperative learning capabilities as well as acquiring fundamental knowledge of individual majors. However, convergence education developed and implemented by Sciences college or liberal education so far has been mechanical combination of knowledge from different academic fields - not effectively integrated and interdisciplinary education. Given this situation, this research is to develop and propose a "convergence education program based on the development of scientific and cultural contents" as an education tool to enhance capabilities to apply and re-create integrated knowledge as well as acquire and learn existing knowledge. Education program developed in this research aims to achieve two different and sequential capabilities. First is to understand 'Science and Technology' and 'Cultural Archetype' which would be essential and useful to create cultural contents. Second is to develop capabilities to convert this understanding into cultural contents - a storytelling capability. This education program is differentiated in that it defines cultural contents as a medium to converge and integrate science and technology and humanities. By leveraging the concept of cultural content and storytelling, this education program would be able to overcome restrictions of existing interdisciplinary approach. Also, this program would encourage students to try in-depth research and new applications, and develop logical and creative thinking.

"The Waste Land" is Eliot's best known poem. It was first published in 1922 and became a famous poem in modem poetry by the 1940's. The poem is a statement of his personal experience with spiritual crisis, this simple outline is complicated and universalized by being set within the structure of 'the Fisher King legend'. The fisher King legend was studied by Miss Weston in From Ritual to Romance and Sir James Frazer in The Goldon Bough which traced the vegetation myths. It explained the cycle of the seasons in relation to the death and rebirth of a god. The god died in the winter with the death of the vegetation and was reborn in the spring with the rebirth of the vegetation. Sir James Frazer reaced these ancient rituals within the Christian world. He indicated that the death and rebirth of Christ falls within the pattern of this ancient ritual. Also Miss Weston transformed that ancient ritual into Christian terms, and connected it with the Quest for the Holy Grail. Eliot used not only the title, but the plan and a good of the important symbolism of the poem from these two books. "The Waste Land" is a difficult one because of the numerous interruptions in the narrative. On the superficial level, the story covers a 12-hour period in a day. It is also in "the stream of consciousness." It might be called the internal monologue; that is, "the free association of ideas in the mind of the narrator," Eliot experiments with both the idea of time and with the stream of consciousness, He employs a number of quotations and allusion from the Classic literature. So, his technique in "The Waste Land" consists of the juxtaposition of the present with mythcism and religious symbolism derived from the past. The structure of the poem is built out of the contrasts in time. The poem illustrates his conception of the past as an active part of the present. "The Waste Land" has "a symphonic structure" composed of five parts, which are linked by the repeated themes. The theme is the death and salvation of the Waste Land. It is drawn from the Fisher King myths. Moreover, he has absorbed into the structure of this poem the language, phrases, and associations of other writers. It gave the poem the universality both of theme and of pattern. Also, his intricate and fine techniques added the universality to the poet's personal material. At last, the verse pattern of the poem follow the same basic structure as the thematic patterns. Again in symphonic style, the verse varies from section to section. The interruption of real time is associated with the flow of consciousness. Though the poem is a complex structure, there are the interweavings of a great deal of ideas into a simple, brief statement. By these poetic techniques the poem manages to have good harmony and unity between the thematic pattern and narrative structure. "The Waste Land" therefore, became the greatest poem in the 20th century modern world.
