This study, which works to develop a method of focusing on A Quiet Dream by Zhang Lu, explored the structural differences of films and the changes in Zhang Lu's aim and perspective as noted in films, by a review to grasp his internal changes in texts and contextual factors. In A Quiet Dream, Zhang Lu made a filmic attempt that had never been made in the world of films prior to that date. He tried an aesthetic experiment on how films could reorganize the world, by using the effect of obscuring the boundary between reality and dream in films and generating a new narrative regarding filmic reality, actual reality, and the life and artistic truth of the Diaspora. Generally speaking, the changes in the narrative in A Quiet Dream seem to be his resistance against himself and the Diaspora. Thus, in the discussion about A Quiet Dream, relying on the external factors intervening in the relationship between the subject of creation and films is not a useful endeavor at this time. Consequently, it is noted that after settling down in Korea, Zhang Lu could directly approach the changes in the cultural position of films in multilayered ways, where films were the most dynamic part of his life. Due to the changes in the Diaspora, he could obscure the boundary for the first time in the world of films and experiment with how films could escape develop an interesting perspective that deviated from reality, and made a new goal to show new ideas regarding the individual's awareness of the world.

This article analyzes biographies of women participants in Miryang struggle against 765㎸ transmission tower and finds that the experience of state violence under the ideological conflicts works the biographical context of participation in environment movement. The cases analyzed in this article disclose the family member's experience of state violence and their trauma through the participation in social movement. And they legitimize their family member's life, heal their trauma, and live a new life by the social movement participation. But the power of healing trauma comes from solidarity and support in social movement. Findings of this article imply that experiences of state violence have influence on the formation and development of various Korean social movements and we need more solidarity and democracy for healing the trauma occurred by state violence and concealed in individual memory. Findings of this article also suggest the importance of biography documents. Biography documents can contribute to widen and to deepen understandings on the social interaction and social history, because they are the document about people's experience who are excluded from the official history and character culture. Moreover biography documents can compensate the official documents, because they can offer the context to the social actions in the official documents. More accumulations and analyses on biographies can serve to widen and to deepen understanding and explanation of Korean society having multilayered exclusion in the process of the compressed modernization and the history of national division.

In this study, the histological changes of Zacco platypus exposed to discharge from a Wastewater Treatment Plant (WTP), which is a point source, for a long time (2 to 3 years) were compared to the same species at a reference site (Ref.). Overall, tissues displayed various lesions in samples obtained at the point where discharge water from the point source was mixed. In the skin tissue, mucus cells from the epithelial layer expanded to the multilayered epithelium, indicating the immune system was activated. Epithelial cell detachment and proliferation were most prominent in the gills, which may have adversely affected circulation and respiration. Our data suggest immune system collapse was due to stimulation by aquatic substances. Both the fish phase analysis and the water quality analysis demonstrated depreciated conditions at the point source as compared to the reference stream, supporting the histological health evaluation results. These data together suggest a histological approach can also be used to assess water quality, and to an even higher degree when combined with other existing methods. Given the presented evaluation, improvement in the water quality of water discharged from WTP's is required.

Despite several constitutive models have been proposed and applied, it is still difficult to choose a suitable model and to estimate adequate analysis parameters. Furthermore, a cyclic shear behavior under the volume change caused by the seepage is more complex. None of the constitutive model is available at present in the expression of the cyclic behavior of soil under an additional volume change condition by seepage. Therefore, a new geotechnical hybrid simulation system which can control the pore water immigration was developed. The system enables a quantitative evaluation of the residual deformation such as lateral spreading and settlement caused by the liquefaction. The seismic responses in a one-dimensional slightly inclined multilayered soil system are taken into consideration, and the soils are governed by both equation of motion and the continuity equation. Furthermore, the estimation and the selection of the soil parameter for the representation of the strong nonlinearity of the material are not required, because soil behaviors under the earthquake motions are directly introduced instead of a numerical soil constitutive model. This paper presents the concept and specifications of the system. By applying the system to an example problem, the permeability effect on the seismic response during cyclic shear is studied. The importance of the volume change characteristics of sandy soil during and after cyclic shear is shown in conclusion.

In recognition of the increasing social attention paid to the notion of how to die well, this study explored what it is that middle-aged and older Koreans think of as "dying well." Specifically, it was aimed at classifying the perceptions people middle-aged and older have regarding dying well. To this end, we used data from the National Survey on Well-Dying, which was conducted in 2018 by the Korea Institute for Health and Social Affairs, and employed Latent Class Analysis. The demographic characteristics of each of the classified subgroups were identified through technical statistics. The types identified were multilayered depending on the imminence of death, perspectives of the last stages before dying, and the meaning of death in the context of social relationships. These types differed according to gender and subjective health conditions. Based on our findings in this study, we put forward policy suggestions about awareness improvement of personal and social levels, promoting on comprehensive death preparation, providing a system to reduce the cost of medical and nursing expense at the end of one's life, promoting of the right to self-determination regarding death, raising social attention to groups that are least prepared for dying well.

The purpose of this study is to reveal the changing aspects of the Promethean motif in SF movies by examining the use of this motif on the three layers of Promethean myth, Frankenstein motif, and contemporary SF movies in the film Ex Machina (2015). First, the greatest change of Ex Machina on the layer of the Promethean myth (creation of a living being) is that the character square of Prometheus - Epimetheus - Pandora - Zeus has been turned into a triangle of Nathan - Caleb - Ava. This means that there is a lack of the being whose role is to solve the problems caused by the development of science and technology and to bring a happy ending through the human's usurpation of God and eventual replacement as Creator. Second, on the layer of the Frankenstein motif (taste of forbidden knowledge, hybris, and creature's hatred towards the Creator), this film maintains the narrative centered around Dr. Frankenstein and his monster (Nathan and Ava) by making Caleb an eyewitness to the story of the Creator and the creature. Caleb's role is similar to that of Captain Robert Walton of the novel Frankenstein, but the film differentiates itself from the novel through the emphasis of Ava's 'mechanicality.' Third, on the layer of contemporary SF movies, unlike other such films, the revolt of the machine in Ex Machina is not quelled. The machine wins, and its power surpasses that of human beings. This requires the establishment of a new relationship between man and machine, suggesting the 'emergence of a new species' that does not belong to humans. The handling of the Promethean motif by Ex Machina through these various layers serves to enrich the narrative by compounding numerous classics into one motif and going further to introduce fresh elements by diverging from the common storyline. The significance of this study is to demonstrate the use of such multilayered motifs and, through this, the expansion of narrative through it in specific cases.

Cham identities which are socially constructed and multilayered, display their markers in a variety of elements, including homeland attachment to the former Kingdom of Champa, religion, language and cultural traditions, to mention a few. However, unlike other contemporary diasporic experience which binds the homeland and the host country, the Cham diaspora in Cambodia has a unique pattern as it seems to have no voice in the political and economic spheres in Vietnam, its homeland. The relations between the Cham in Cambodia and Vietnam seem to be limited to cultural heritages such as Cham musical traditions, traditional clothing, and the architectural heritage. Many Cham people have established networks outside Cambodia with areas of the Muslim world, like Malaysia, Indonesia, southern Thailand and the Middle Eastern countries. Pursuing education or training in Islam as well as working in those countries, especially Malaysia has become a way for the Cham to widen their networks and increase their knowledge of particularly, Islam. Returning to Cambodia, these people become religious teachers or ustadz (Islamic teachers in the pondok [Islamic boarding school]). This has developed slowly, side by side with the formation of their identity as Cham Muslims. Among certain Cham, the absence of an ancient cultural heritage as an identity marker has been replaced by the Islamic culture as the important element of identity. However, being Cham is not a single identity, it is fluid and contested. Many scholars argue that the Cham in Cambodia constitute three groups: the Cham Chvea, Cham, and Cham Bani (Cham Jahed). The so-called Cham Jahed has a unique practice of Islam. Unlike other Cham who pray five times a day, Cham Jahed people pray, once a week, on Fridays. They also have a different ritual for the wedding ceremony which they regard as the authentic tradition of the Cham. Indeed, they consider themselves pure descendants of the Cham in Vietnam; retaining Cham traditions and tending to maintain their relationship with their fellow Cham in Central Vietnam. In terms of language, another marker of identity, the Cham and the Cham Jahed share the same language, but Cham Jahed preserve the written Cham script more often than the Cham. Besides, the Cham Jahed teaches the language to the young generation intensively. This paper, based on fieldwork in Cambodia in 2010 and 2011 will focus on the process of the formation of the Cham identity, especially of those called Cham and Cham Jahed.

This study was conducted to investigate the effects of temperature and light conditions on the vigor and growth responses of red pepper(Capsicum annuum L.) seedlings in the nonheated plastic houses with triple and quadruple coverings during winter. The results obtained were as follows ; 1. The growth in terms of plant height, number of leaves, leaf area and dry weight of each organ was reduced up to 50% in the triple coverings compared to quadruple ones. The greatest difference between the triple coverings and quadruple ones was the leaf area, showing two to five times larger in the quadruple ones. Therefore, the differences of the early environmental conditions during raising seedling stage was well reflected. 2. The leaf expansion in the early stage of seedling was delayed in the triple coverings and subsequently crop growth rate(CGR) significantly reduced. The specific leaf area (SLA) in the triple coverings was less than quadruple ones. The net assimilation rate (NAR) was increased in the early stage of seedlings and then reduced in the quadruple coverings. In triple ones, however, the great reduction showed at six weeks after sowing and then increased sharply. 3. The linear relationship among leaf area, total dry weight and leaf dry weight was observed in the all experimental areas, while between leaf area and crop growth rate only in the quadruple coverings, and between leaf area and net assimilation rate in both triple and quadruple ones. 4. The dry matter partitioned to the leaf increased up to six weeks after sowing in the triple coverings but reduced in the stem and root. However, the adverse results were obtained in the quadruple ones. 5. In the triple coverings, the number of branches showed the exponential increment while fruit weight showed linear increment in both triple and quadruple ones. Higher yield was obtained in the quadruple ones. 6. The shoot dry weight among the characteristics of seedlings was greatly contributed to the yield of red pepper after transplanting. Accordingly, one of the decisive criterion for good quality of red pepper seedlings was determined by the highest correlation between shoot dry weight of growing plant and fruit yield of pepper plant.

PbWO$_4$ can be densified at 85$0^{\circ}C$ and it shows fairy good microwave dielectric properties; dielectric constant($\varepsilon$$_{r}$) of 21.5, quality factor(Q $\times$f$_{0}$) of 37,224 GHz, and temperature coefficient of resonant frequency($\tau$/suf f/) of -31ppm/$^{\circ}C$. Due to its low sintering temperature, PbWO$_4$ can be used as a multilayered chip component at microwave frequency with high electrical performance by using high conductive electrode metals such as Ag and Cu. However, in order to use this material for microwave communication devices, the $\tau$$_{f}$ of PbWO$_4$ must be stabilized to near zero with high Q$\times$f$_{0}$. In present study, PbWO$_4$ was modified by adding TiO$_2$, B$_2$O$_3$, and CuO in order to improve the microwave dielectric properties without increasing the sintering temperature. The addition of TiO$_2$ increased the $\tau$$_{f}$ and $\varepsilon$$_{r}$, due to its high rr(200ppm/$^{\circ}C$) and $\varepsilon$$_{r}$(100). However, the addition of TiO$_2$ reduced the Q$\times$f$_{0}$ value. When the mot ratio of PbWO$_4$ and TiO$_2$ was 0.913:7.087, near zero $\tau$$_{f}$(0.2ppm/$^{\circ}C$) was obtaibed with $\varepsilon$$_{r}$=22.3, and Q$\times$f/$_{0}$=21,443GHz. With this composition, various amount of B$_2$O$_3$ and CuO were added in order to improve the quality factor. The addition, of B$_2$O$_3$ decreased the $\varepsilon$$_{r}$. However, increased Q$\times$f$_{0}$ and $\tau$$_{f}$. When 2.5 wt% of B$_2$O$_3$ was added to the 0.913PbWO$_4$-0.087TiO$_2$ ceramic, $\tau$$_{f}$ =8.2, $\varepsilon$$_{r}$=20.3, Q$\times$f$_{0}$=54784 GHz. When CuO added to the 0.913PbWO$_4$-0.087TiO$_2$ ceramic, $\tau$$_{f}$ was continuously decreased. And $\varepsilon$$_{r}$ . and Q$\times$f$_{0}$ were increased up to 1.0 wt% then decreased. At 0.1 wt% of CuO addition, the 0.913PbWO$_4$-7.087Ti0$_2$ Ceramic Showed $\varepsilon$$_{r}$=23.5, $\tau$$_{f}$=4.4ppm/$^{\circ}C$, and Q$\times$f$_{0}$=32,932 GHz.> 0/=32,932 GHz.X>=32,932 GHz.> 0/=32,932 GHz.

The purpose of this study is to analyze the impacts of three-dimensional land cover on changing urban air temperatures and to explore some strategies of urban landscaping towards mitigation of heat build-up. This study located study spaces within a diameter of 300m around 24 Automatic Weather Stations(AWS) in Seoul, and collected data of diverse variables which could affect summer energy budgets and air temperatures. The study also selected reflecting study objectives 6 smaller-scale spaces with a diameter of 30m in Chuncheon, and measured summer air temperatures and three-dimensional land cover to compare their relationships with results from Seoul's AWS. Linear regression models derived from data of Seoul's AWS revealed that vegetation volume, greenspace area, building volume, building area, population density, and pavement area contributed to a statistically significant change in summer air temperatures. Of these variables, vegetation and building volume indicated the highest accountability for total variability of changes in the air temperatures. Multiple regression models derived from combinations of the significant variables also showed that both vegetation and building volume generated a model with the best fitness. Based on this multiple regression model, a 10% increase of vegetation volume decreased the air temperatures by approximately 0.14%, while a 10% increase of building volume raised them by 0.26%. Relationships between Chuncheon's summer air temperatures and land cover distribution for the smaller-scale spaces also disclosed that the air temperatures were negatively correlated to vegetation volume and greenspace area, while they were positively correlated to hardscape area. Similarly to the case of Seoul's AWS, the air temperatures for the smaller-scale spaces decreased by 0.32% ($0.08^{\circ}C$) as vegetation volume increased by 10%, based on the most appropriate linear model. Thus, urban landscaping for the reduction of summer air temperatures requires strategies to improve vegetation volume and simultaneously to decrease building volume. For Seoul's AWS, the impact of building volume on changing the air temperatures was about 2 times greater than that of vegetation volume. Wall and rooftop greening for shading and evapotranspiration is suggested to control atmospheric heating by three-dimensional building surfaces, enlarging vegetation volume through multilayered plantings on soil surfaces.
