STRUKTUR KEPRIBADIAN DAN KONFLIK BATIN YANG DIALAMI TOKOH SEITA DALAM ANIME HOTARU NO HAKA (KAJIAN PSIKOLOGI SASTRA)

ABSTRACT Pramadhani, Rizza Febry. 2017. “Struktur Kepribadian dan Konflik Batin yang Dialami oleh Tokoh Seita dalam Anime Hotaru no Haka”. Thesis, Department of Japanese Studies Faculty of Humanities, Diponegoro University. First Advisor Yuliani Rahmah, S.pd, M.Hum. This research discusses about Seita’s personality conflict in Hotaru no Haka anime. Seita is a Japanese boy that has been one of the victim in 1945 World War. After that, Seita and his sister Setsuko have lost their home and even their parent. This condition forces Seita and his sister to live their life by themselves, and causes various mental pressure to Seita. From this anime, we can see how Seita as a little boy that must carry so much problem that usually happen to adult people and maybe even they can’t bear it. The purpose of this research are to answer the problem about personality conflict of Seita based on Hotaru no Haka anime by Ghibli Studio. The methods which used in this research are fiction characterication method and Sigmund Freud’s personality method. The result shows that although at first Seita’s ego always abandon his superego, but that’s not for a long time. Because if Seita’s ego is abandoning his superego, and his id is fulfilled, there would be fear in Seita. In example, at the second conflict, Seita’s id wants him to give his sister a nutritious food, but because their condition and Seita wasn’t able to work, his ego follows his id. Seita decided to steal the food in someone’s farm because his ego. His id is fulfilled, but somebody knows about Seita’s theft, so Seita’s superego appears. His superego wants Seita’s ego to fulfill his id but in the right way. So, his ego decided Seita won’t steal again to fulfill his sister’s needs.

Effect of the Sintering Conditions on the Neck Growth during the Powder Bed Fusion with Electron Beam (PBF-EB) Process

A distinctive characteristic of the powder bed fusion with electron beam (PBF-EB) process is the sintering of the powder particles. For certain metallic materials, this is crucial for the success of the subsequent step, the melting, and, generally, the whole process. Despite the sintering mechanisms that occur during the PBF-EB process being similar to well-known powder metallurgy, the neck growth rates are significantly different. Therefore, specific analyses are needed to understand the influence of the PBF-EB process conditions on neck growth and neck growth rate. Additionally, some aspects, such as the rigid body motion of the particles during the sintering process, are still challenging to analyze. This work systematically investigated the effects of different particle diameters and particle diameter ratios. Additionally, the impact of the rigid body motion of the particles in the sintering was analyzed. This work demonstrated that the sintering results significantly depended on the EB-PBF process conditions

A surface energy-budget model coupled with a Skewed Puff Model for investigating the dispersion of radionuclides in a sub-tropical area of Brazil

An air pollution model (Skewed Puff Model, SPM) based on the Monin-Obukhov similarity theory was applied to investigate the atmospheric radionuclide dispersion at Iperó in Brazil, the location of a nuclear industrial installation. The SPM numerical simulations were carried out using as input 5-minute averaged wind speed and direction observed at 11.5 m, friction velocity and the Monin-Obukhov length supplied by the surface energy-budget model, along with PBL height, estimated from empirical equilibrium expressions for the nighttime and Mixed-Layer model for the daytime. The agreement between the observed and simulated sensible and latent heat fluxes, friction velocity and Monin-Obukhov length, within a level of confidence of 99.9% indicates that the internal parameters chosen for the surface energy-budget model are representative of the interface soil-vegetation conditions at Iperó. The mean concentration field at the surface was estimated assuming that a hypothetical accident at Iperó produced a continuous emission from a 10 m high point source for 18 hours during the summer of 1993 and for 36 hours during the winter of 1992. The results indicated that, in the case of an accident, the highest concentration values are located near to the source and most of the contaminated area is within a 5 kilometers range, in both seasons. The shape of the contaminated area is defined by the wind speed pattern

Development of a grid-dispersion model in a large-eddy-simulation–generated planetary boundary layer

Numerical simulations of dispersion experiments within the planetary boundary layer are actually feasible making use of Large Eddy Simulations (LES). In Eulerian framework, a conservation equation for a passive scalar may be superimposed on LES wind/turbulence fields to get a realistic description of timevarying concentration field. Aim of this work is to present a numerical technique to solve the Eulerian conservation equation. The technique is based on Fractional Step/Locally One-Dimensional (LOD) methods. Advection terms are calculated with a semi-Lagrangian cubic-spline technique, while diffusive terms are calculated with Crank-Nicholson implicit scheme. To test the grid model, the dispersion of contaminants emitted from an elevated continuous point source in a convective boundary layer is simulated. Results show that the calculated concentration distributions agree quite well with numerical and experimental data found in the literature

Social Presence in Computer-mediated Communication of Thai EFL Learners

Master of Arts (Teaching English as an International Language), 2023According to previous research, computer-mediated communication (CMC) via social media such as Facebook can provide non-threatening learning atmosphere to foster a more relaxed and condusive learning environment to EFL learners hence enhancing EFL learners’ engagement through increased social contact. Understanding Social Presence (SP) indicators can assist in improving the quality of learning through rich interaction and greater engagement. This helps to maximize the potential of CMC for English laanguge learning. Despite previous studies that have looked at interactions in Thai contexts through the lens of SP, there is still much to be discovered. In addition, the value of Social Presence in CMC for language learners, as well as for online learning, has been previously explored in previous study. Though there are few studies on this subject in Thai EFL contexts, there is a lack of research concerning out-of-class activities that can engage students by helping them to overcome the anxiety they feel in a virtual learning environment. The aim of this study was to investigate the ways Thai EFL learners interacted in a computer-mediated communication (CMC) environment based on Social Presence (SP) and to explore learners’ perception on their interaction on Facebook Messenger Group Chat. A mixed-method design was adopted. Fifty-two undergraduate learners in a university in Southern Thailand were selected and divided into groups of four to five to partake in the exchange of Facebook Messenger group messages for 7 weeks. Exchanged messages were collected and analyzed using quantitative counting to find out the frequency of SP indicators in the group chat. A set of questionnaire with open-ended questions was distributed to obtain learners’ 2 vi perception. The former was subjected to descriptive analysis while the latter was subjected to thematic analysis. Results showed that 40% of the messages were interactive responses, followed by affective and cohesive ones, indicating that when Thai EFL learners were virtually present and to appreciate others, they tended to put forward to contribute in the discussion. Furthermore, the learners demonstrated their SP by exhibiting acknowledgement, using paralanguage, using greetings and salutations respectively. Two indicators gained the least: emotion and personal advice. Surprisingly, one indicator, course reflection, was not observed in the text messages. It was found from the questionnaire that cohesive category had the highest total mean score (M = 4.29, SD = .400), followed by affective and interactive ones. The results indicated that the learners strongly agreed that the “sense of belongingness” was felt throughout the online interaction. In addition, as qualitative results, three themes emerged: building group cohesion, immediacy, and an opportunity for English interaction, suggesting that English language use via CMC was valued by the learners beyond the classroom environment. This mixed method study shed light on how Thai EFL learners communicated and interacted digitally using English via Facebook Messenger Group Chat as a designed CMC learning environment with the meaningful negotiation. By understanding their interaction online through SP, the results of this study provided the empirical evidence of how Thai EFL learners socially and emotionally presented themselves online with the exposure to English outside of the classroom as a necessity of language input for EFL learners to build an online community. It concludes with the discussion of the SP implications, limitation and recommendations for EFL educators, learners and stakeholders
