In what was labeled the "nut rage" incident, the vice president of Korean Air, Hyun-Ah Cho (Heather Cho), demonstrated behavior that exemplifies corporate transgression and deviation from societal moral standards toward a flight attendant aboard a flight. Such behavior instigated the public to express negative sentiment on various social media platforms. This study investigates word-of-mouth network on YouTube in response to the crisis, patterns of co-commenting activities across selected YouTube videos, as well as public responses to the incident by employing social and semantic network analysis. A total of 512 YouTube videos featuring the crisis from December 8, 2014 through November 11, 2018, and 52,772 public comments to the videos were collected. The central videos in the network successfully attracted the public's attention and engagements. The results suggest that the video network was decentralized, with multiple videos acting as hubs in the network. The public commented on various videos instead of focusing on a few. The contents of influential videos uploaded by popular news organizations revealed not only Cho's behaviors related to the nut rage crisis but also unrelated illegal behaviors and the moral violations committed by the family members of Korean Air. The public attached derogatory remarks to Cho and her family, and the comments also addressed ethical concerns, management issues of the company, and boycott intentions. The results imply that adverse public reaction was related to the long-standing problem caused by family ownership and governance in large Korean corporations. This Korean Air scandal illustrates backlash toward a leadership breakdown by the family business conglomerate prevalent in the Korean society. This study provides insights for effective handling of similar crises.

Although monoculture methods have been remarkably useful due to their simplicity, they have serious limitation because of the different types of cells communication with each other in many physiological situations. We demonstrated levels of markers of endothelial dysfunction such as tumor necrosis factor-$\alpha$ (TNF-$\alpha$) and interleukin-1$\beta$ (IL-1$\beta$) as well as stimulation of receptor of advanced glycation endproducts (AGEs) on monoand co-culture system such as only monocyte (THP-1) cultivation system, only endothelial cell (HUVEC) cultivation system, and co-cultivation system of THP-1 and HUVEC. The mRNA levels of TNF-$\alpha$ and IL-1$\beta$ on HUVEC increased by the co-culture with monocyte after 4 hr at 100 ${\mu}g/mL$ glyceraldehyde-AGE. The secreted protein contents into medium of TNF-$\alpha$ and IL-1$\beta$ increased after 8 hr approximately 2~2.5 times compared to mono-cultivation. In contrast, the mRNA level of receptor of AGE (RAGE) was relatively insensitive on the co-culture system. The mediators by which monocytes activate endothelial cell have not been fully elucidated. In this study we confirmed production of soluble cytokines such as TNF-$\alpha$ and IL-1$\beta$ by monocytes. Use of monocyte conditioned medium, which contains both cytokines, can activate endothelial cell.

A theroretical study was made on the psychodynamism of somatoform disorder. Somatoform disorder is caused by a defense mechanism of somatization. Somatization is the tendency to react to stimuli(drives, defenses, and conflict between them) physically rather than psychically(Moore, 1990). Ford(1983) said it is a way of life, and Dunbar(1954) said it is the shift of psychic energy toward expression in somatic symptoms. As used by Max Shur(1955), somatization links symptom formation to the regression that may occur in response to acute and chronic conflict. In the neurotic individual psychic conflict often provokes regressive phenomena that may include somatic manifestations characteristic of an earlier developmental phase. Schur calls this resomatization. Pain is the most common example of a somatization reaction to conflict. The pain has an unconscious significance derived from childhood experiences. It is used to win love, to punish misdeeds, as well as a means to amend. Among all pains, chest pain has a special meaning. Generally speaking, 'I have pain in my chest' is about the same as 'I have pain in my mind'. The chest represent the mind, and the mind reminds us about the heart. So we have a high tendency to recognize mental pain as cardiac pain. Kellner(1990) said rage and hostility, especially repressed hostility, are important factors in somatization. In 'Psychoanalytic Observation on Cardiac Pain', psychoanalyst Bacon(1953) presented clinical cases of patients who complained of cardiac pain in a psychoanalytic session that spread from the left side of their chests down their left arms. The pain was from rage and fear which came after their desire to be loved was frustrated by the analyet. She said desires related to cardiac pain were dependency needs and aggressions. Empatic relationship and therapeutic alliances are indispensable to psychotherapy in somatoform disorder. The beginning of therapy is to discover a precipitating event from the time their symptoms have started and to help the patient understand a relation between the symptom and precipitating event. Its remedial process is to find and interpret a intrapsychic conflict shown through the symptoms of the patient. Three cases of somatoform disorder patients treated based on this therapeutic method were introduced. The firt patient, Mr. H, had been suffering from hysterical aphasia with repressed rage as ie psychodynamic cause. An interpretation related to the precipitating event was given by written communication, and he recovered from his aphasia after 3 days of the session. The second patient was a dentist in a cardiac neurosis with agitation and hypochondriasis, whose psychodynamism was caused by a fear that he might lose his father's love. His symptom was also interpreted in relation to the precipitating event. It showed the patient a child-within afraid of losing his father's love. His condition improved after getting a didactic interpretation which told him, to be master of himself, The third patient was a lady transferred from the deparment of internal medicine. She had a frequent and violent fit of chest pains, whose psychodynamic cause was separation anxiety and a rage due to the frustration of dependency needs. Her symptom vanished dramatically when she wore a holler EKG monitor and did not occur during monitoring. By this experience she found her symptom was a psychogenic one, and a therapeutic alliance was formed. later in reguar psychotherapy sessions, she was told the relaton between symptoms and precipitating events. Through this she understood that her separation anxiety was connected to the symptom and she became less terrifide when it occurred. Now she can travel abroad and take well part in social activities.

China's airline industry is experiencing a booming development as one hand, on the other hand the incidents involving unruly behaviour on board aircraft also becomes a growing concern for the whole industry. The thesis examines the basic issues concerning the unruly behaviour, such as definition of unruly behaviour, the impact and root causes of unruly behaviour. Then it focuses on the China's legal sources governing the problem of unruly behaviour. Generally speaking, China's legislation with this respect is systematic and self-contained, except some minor shortcomings which need to be revised. Finally the thesis holds the view that the preventative measures jointly contributed by all the parties concerned are something more important than the legislation itself.

There are many prior studies for more natural Human-Computer Interaction. Until now, the efforts is continued in order to recognize motions in various directions. In this paper, we suggest a user-specific recognition by hit detection method using Kinect camera and human proportion. This algorithm extracts the user-specific valid recognition rage after recognizing the user's body initially. And it corrects the difference in horizontal position between the user and Kinect, so that we can estimate a action of user by matching cursor to target using only one frame. Ensure that efficient hand recognition in the game to take advantage of this method of suggestion.

This research was performed to investigate the developmental ability of mouse oocytes following cold-culture(4$^{\circ}C$) in vitro. When the oocytes were fertilized after 10 hour cold-culture in D-PBS or Ham's F10 with 0.3% BSA, the cleavage rage of the oocytes was not different in the rate of oocytes fertilized in vitro without cold-culture(126/189, 66.2% vs 88/133, 66.7%) and also the rate of embryos developed to blastocyst did not(123/189, 65.1% vs 82/133). But, when the time of the cold-cultre was extended from 10 to 24 hours, the rate of embryos developed to blastocyst was slightly decreased(73.5% vs 52.2%). However, when the oocytes were cultured for 10 and 24hours at 37$^{\circ}C$, the rate of oocytes developed to blastocyst was significantly decreased than that of oocytes following cold-culture. By the results of this study, it'll be possible to utilize effectively the cold-culture of the oocytes when in vitro fertilization is delayed.

Two porcelain crab species, Aliaporcellana pygmaea (De Man, 1902) and Lissoporcellana nakasonei (Miyake, 1978), are reported here for the first time from Korean waters based on specimens collected from Jeju Island, Korea. The genus Aliaporcellana Nakasone and Miyake, 1969, and Lissoporcellana Haig, 1978 are also reported here for the first time in Korea. Aliaporcellana pygmaea has a wide distribution. The specimen reported here is the most northern record of this species. While, Lissoporcellana nakasonei, associated with anthozoans, was known for distributing range from New Caledonia to southern Japan. As a result, the distribution rage of L. nakasonei is changed to Korea. Now, 12 species of porcelain crabs have been reported in Korean waters.

Hot deformation behavior of Udimet 720Li was characterized by compression tests in the temperature range of $1025^{\circ}C\;to\;1150^{\circ}C$ and the strain rate rage of $0.0005s^{-1}\;to\;5s^{-1}$. In order to characterize the dependence of flow stress on strain, strain rate and temperature, a constitutive equation based on hyperbolic sine formation was used. Isothermal forging of Udimet 720Li was performed in the temperature range $1050-1150^{\circ}C$ at strain rates of $0.05s^{-1}\;and\;0.005s^{-1}$. FE simulation was also carried out to predict deformation microstructures during isothermal forging.

A new tower internal, which is called CSE, is presented. The CSE is composed of a nozzle perforated in its bottom along the entire periphery and equipped with a multi vane axial swirler at the inlet and hollow cylindrical separator at the outlet of the nozzle. According to the experimental work for obtaining the necessary hydraulic information of the CSE, which is used for preliminary design of a separation column, the CSE showed a stable operation over the wide rage of gas/liquid ratio. However, it caused large pressure drop due to the high gas velocity which should carry liquid droplets through the element. The high pressure drop may cause problems in energy recovery and the application of the CSE can be limited to the high pressure columns. Assuming that the tray efficiency of the CSE is the same with the existing separation columns, the results of the column design showed the size reduction of the column diameters by 30 to $40\%$ and investment cost saving, depending on operating conditions. The application of the CSE to separation column may also contribute to the de-bottlenecking the existing column.
