This experiment was conducted to elucidate the effect of the midsummer drainage times on lodging characters, field lodging and yield in direct seeding rice culture in puddled soil. Dongjinbyeo was seeded at May 11 by seeding machine with 4cm of furrow depth and drained, one（50days after seeding DAS）） two （30DAS and 50DAS）, and three times （30DAS, and 50DAS and 60DAS）. The results are as follows. Culm length was shorten and the wall of N3, N4 were thicken as the drain-age times were increased. As the drainage times were increased breaking weights were increased but the lodging index were decreased. Lodging was occurred seriousely at none drainage, but wasn't occurred two or three times drainage. Yield was higher at 1~2 times drainage compared with none and three times drainage. Therefore, two times midsummer drainage is recommend-able water management method for direct seeding rice culture in puddled soil.

To find out the optimum seeding rate in corrugated water seeded rice, field experiment was carried out at Yeongdeog Substation of the National Yeongnam Agricultural Experiment Station for two years, 1994 and 1995. A rice cultivar Donghaebyeo, was seeded on May 15 with five seeding rate from 3kg /10a to 7kg /10a. The number of seedling stand per unit area was curvilinearly increased with seeding rate. In characteristics of rice plant associated with lodging, the plant height, fresh weight per tiller, Culm wall thickness and ratio of gravity center were not significantly different among seeding rates, but the breaking strength of 4th internode was slightly decreased with increasing seeding rate and thus, lodging index was generally greater at higher seeding rate than lower seeding rate. Field lodging was observed at 1~3 degree in seeding rate of 5~7kg /10a. Panicle number per unit area was generally increase with increase of seeding rate, while ratio of ripened grain was decreased with increase of spikelet number. Milled rice yield was curvilinearly increased with seeding rate. The optimum seeding rate in the highest rice yield was 4.8kg /10a in 1994, and 4.3kg /a in 1995, respectively.

This study examined the involuntary retirement of executives in conglomerates based on Williams' need-threat temporal model of ostracism(2009), which explains the psychology of individuals facing social exclusion in the stages of reflexive, reflective and resignation. In-depth interviews were conducted on 15 retirees from conglomerates, and their contents were used for phenomenological method of analysis. As a result, in the reflexive stage of need-threat temporal model of ostracism, they experienced cognitive panic and emotional panic immediately following retirement. Due to an unexpected shocking experience of retirement notice, they experienced cognitive numbness first, and repressed the following negative feelings cognitively to hide them. In the reflective stage, retirees dream of 'a complete restoration to their best performance in the past', but as such expectation fails, they don't adjust to the reality more due to 'unrealistic thought', 'self-deception', and 'shift responsibility'. In resignation stage, a long-term failure to satisfy the desire led them to experience a sense of defeat and helplessness. Such results were reviewed and compared to Williams' need-threat temporal model of ostracism, and the implications of such result on the nation, companies and retirees in terms of the response to retirement.

The scientist-led Research and Education (R&E) program aims to strengthen gifted science students' research capabilities under the guidance of scientists. Students' actual research experiences in scientist-led R&E activities range from understanding how scientists conduct research to actively participating in research. To develop R&E that promotes student agency, i.e., student participation, this study aimed to identify the pedagogical characteristics that supported gifted science students' agentic participation in the scientist-led R&E program. We conducted interviews with learners and scientists in three teams undertaking R&E activities every three months. The interview covered their perceptions of R&E activities, student participation, and scientists' support for the activities. The recordings and transcripts of the interviews were used as primary data sources for the analysis. The trajectory of each team's activities, as well as the learners' and scientists' dynamic positioning were identified. Based on this analysis, we inductively identified the pedagogical characteristics that emerged from classes in which the scientists supported the students' learning and engagement in research. Regarding agency, three types of student participation were identified: 1) the sustained exercise of agency, 2) the initial exercise and subsequent discouragement of agency, and 3) the continuous non-exercise of agency. Two pedagogical characteristics that supported the learners' agentic participation were identified: 1) opportunities for students to take part in research management and 2) scientist-student interactions encouraging learners to present expert-level ideas. This study contributes to developing pedagogies that foster gifted science students' agentic participation in scientist-led R&E activities.

Yorgos Lanthimos' The Killing of a Sacred Deer (2017) uses Iphigeneia in Aulis written by Euripides, one of the three great Greek tragedies writers, as the archetypal narrative. Thus, Lanthimos introduces a mythical world stained with 'blood violence by a divine being' within the cinematic diegesis of a modern American metropolis. And the mythical motifs of curses and scapegoats are varied. This thesis tried to read the scapegoat mechanism, the oldest mechanism of escape from the crisis of collective sacrifice, and the imitative and mutual characteristics of desire and violence through René Girard through the mythical world built in the modern time and space of the film. Martin places a cursed oracle on Steven when his desire to place him in his father's place is thwarted. The 'good' reciprocity between two people is rapidly transformed into a 'bad' reciprocity. The Killing of Sacred Deer is an excellent portrayal of how the scapegoat mechanism works through Steven's family. The selection of the scapegoat by lot gives the sacrificial lamb a sacred character thanks to its divine nature, and the scapegoat becomes a sacred being, and the family order is re-established.

The North Korean military's maneuver toward Honam was the fastest maneuver the North Korean army had demonstrated during the Korean War, and it was a threatening attack that forced the Korean and Allied forces to fully adjust the defenses of the Nakdong River. However, when this study analyzed the North Korean military's maneuver toward Honam in terms of indirect approach strategy, there were a number of factors that inevitably led to its failure. In terms of implementing the indirect approach strategy, the North Korean military cited a number of failure factors, including the dispersion of combat forces, the inflexibility of changing the line of operation, the maneuvering of ground forces, and the lack of psychological distaction. However, the North Koreans were preparing for a final "surprise attack," in which the 7th Division, which was following the North Korean 6th Division, took another diversion and attempted to attack in the direction of Tongyeong. With this, the North Koreans intended to break through the Nakdong River defenses and head for Pusan. However, the North Korean attack was ultimately thwarted by the Korean Navy and Marine Corps' Tongyeong Amphibious Operation. With a swift maneuver using the sea as a maneuvering space, the Navy and Marine Corps occupied key points first, creating an advantageous situation and fending off an attack by the North Korean 7th Division. The Navy and Marine Corps' Tongyeong Amphibious Operation finally thwarted the North Korean military's maneuver toward Honam, thus maintaining the Nakdong River defenses.

This paper is aimed at exploring a multi-racial, multi-ethnic, and multi-cultural trianglulation of Black, White, and Korean American race relations connected to a large-scale disturbance in the 1992 Los Angeles riots. The second generation Korean American Steph Cha's Your House Will Pay (2019) focuses on a social portrait of the racially marginalized beings as Korean immigrant merchants and African American native consumers. This family saga explores issues resulting from racial hierarchy, racialized stereotypes, and historical marginalization in the internalized sociometry of race and class inequality. This work grapples with issues involved in a sociocultural web of racial triangulation under the white dominant structure, and ensuing intergroup conflicts of social minorities in the economic geography of urban space. It opens up civil discussions for transracial, transethnic, and transcultural interactions and coexistence. It ultimately leads to extending young people's minds for a deep understanding of the socioecomonic landscape of racial matrix, and enhancing the cultural literacy for a better awareness of social empathy and the communal respect of life.

Die Gegenwart steht den Tatsachen der Gewalt gegenüber. Wesentlich destruktive Techniken können den kollektiven Tod des Menschen als Gattung produzieren. Die Destruktivität dieser Techniken ist durch Skeptizismus geistesgeschichtlich gerechtfertigt. Ebelings Fundamentalpragmatik ist Reflexionstheorie der widerstandsfähigen Vernunft, welche einer Sozialisierung derjenigen Gewalt widersteht, die in einer gegenwärtigen Aussicht auf universale Selbstdestruktion des Menschen Tod produziert. Selbstbewußtsein (Apperzeption) ist bei Kant Selbstbewußtsein in Gegenstandsbewußtsein. Mit kritischer Auslegung von Kant zeigt Heidegger endlich, daß der Tod der Selbstbeziehung des konkreten Daseins als des In-der-Welt-seins gehört. Aber seine existenziale Analytik berücksichtigt nur individuelles Dasein zum Tode und vernachlässigt die Allgemeinheit des menschlichen Todes bzw. die dem allgemeinen Untergang widerstehende Vernunft. Apel kritisiert ein solipsistisches Erbe von Kants Bewußtseinsphilosophie und präsentiert ein Argument der Letztbegründung zur Überwindung des Skeptizismus. Aber seine Transzendentalpragmatik vernachlässigt die Endlichkeit des menschen und zeigt ein Defizit der fundamentalpragmatischen Vereinigung der Vernunft und des Todes. Aufgrund des gegenwärtigen Todesbewußtseins, das Heideggers Todesdeutung transformiert, rekonstruiert Ebelings Existentialpragmatik Heideggers Dasein zu Existenzsubjekt. Seine Fundamentalpragmatik vollzieht diejenige Erstbegründung, die zwischen der existentialpragmatischen Endbegründung des Todes und der transzendentalpragmatischen Letztbegründung vermittelt, und damit bestimmt sie Vernunft als Widerstandsbewußtsein (das bewußte Sein) gegen den Tod. Also ist sie neue transzendentalphilosophische Bewußtseinsphilosophie, die mit der neuen Selbstbestimmung der Vernunft entwickelt wird.

In Korea, Pbichim refers to a psychological state caused by emotional damages that can occur within close relationships. In this state, one might feel reluctant to express one's feelings directly to the other party. It is also possible that Pbichim transforms into anger. This study is aimed to define the term Pbichim as an indigenous psychological concept. In Korea, it is common to express one's feelings indirectly and read the other party's inward thoughts. Pbichim reflects those cultural aspects. In order to examine the representation of Pbichim in Korea, we developed a questionnaire consisting of 15 open-ended questions. The participants were 119 undergraduate and graduate students at Korea University, and the data was analyzed qualitatively. As a result, four different aspects of Pbichim (unsatisfied expectation, being ignored, being alienated, and power struggle) could be differentiated by the situation in which people are likely to present Pbichim. The personality traits of Pbichim, the way of relieving it, as well as positive and negative functions of Pbichim were also elicited. In addition, it was found that Pbichim (the concept that has been negatively perceived) has an important function in maintaining and improving an interpersonal relationship in Korea. Lastly, the importance of mind reading within a certain cultural context is discussed.

This study analyzed the resilience process of persons with disabilities using the grounded theory approach. To conduct this study, the researcher conducted in-depth interviews with 8 persons with disabilities. In data analysis, this study identified 393 concepts on the resilience process of persons with disabilities and the concepts were categorized into 45 sub-categories and 18 primary categories. In the paradigm model on the resilience process of persons with disabilities, it was identified that casual conditions included 'unawareness of disability before being disability', 'extreme pain', 'repressing psychological pain', and the contingent conditions were 'dis-empowerment by staying in home', 'isolation by himself with difficulty in accepting the disability', 'experience of frustration from social barriers with prejudice against persons with disabilities'. Also, it was identified that the resilience process could be dependent on the type and the degree of the disability, the gender, and the length of time being disability. In spite of the casual and contingent conditions, the central way in which persons with disabilities could acquire resilience was identified as 'enhancement of the power of positive thinking'. The control conditions which accelerate or retard central phenomenon were 'the awareness of not being alone through family, friends, neighborhood and the social system' externally and 'finding purpose in life through religion and help from other persons with disabilities', internally. The action/interactional sequences enhanced the efforts, self searching and active acting, and as a result, persons with disabilities could find comfort in life, participate in society and change the perspective of disability in society. The core categories of resilience process in persons with disabilities were a belief in affirmation and choice of life by initiative. In the process analysis, stages developed in the following: 'pain', 'strangeness', 'reflection', 'daily life'. This stage was more continuous and causal than discrete and complete. In this process, the types of resilience of persons with disabilities are divided into 'existence reflection', 'course development', 'implicit endeavor', and 'active execution'. This study showed the details of the paradigm models, the process and types with an in-depth understanding of the resilience process of persons with disabilities using grounded theory as well as theory construction and policy and clinical involvement on the study of persons with disabilities.
