Past research showed that presence of others induces morally desirable behavior and stricter judgments. That is, presence of others makes people become a moral being. On the other hand, little research has been conducted to test what effects facial expression of others have on moral judgments. In this research, we tested the effects of emotion exposed by facial expression on moral judgments. To this end, we presented descriptions of immoral or prosocial behavior along with facial expression of various emotions (in particular, disgust and happiness), and asked participants to make moral judgments on the behavior in the descriptions. In Experiment 1, facial expression did not affect moral judgments, but variability of judgments was increased when descriptions and facial expression were incongruent. In experiment 2, we modified potential reasons of the null effect and conducted the experiment using the same procedure. Subjects in Experiment 2 made stricter judgments with disgust faces than with happy faces for immoral behavior, but the effect did not occur for prosocial behavior. In Experiment 3, we repeated the same experiment after having subjects to consider themselves as the actor in the descriptions. The results replicated the effects of facial expression in Experiment 2 but there was no effect of the actor on moral judgments. This research showed that facial expression of others specifically affects moral judgments on immoral behavior but not on prosocial behavior. In general discussion, we provided further discussion on the results and the limitations of this research.

Cement is one of the most commonly used materials in the construction and civil engineering industry. However, emissions of carbon dioxide generated during the production of cement have been linked to climate change and environment pollutants. In order to replace cement, many studies have been actively performed research to utilizing Blast Furnace Slag(BFS), which is a byproduct of the steel industry. This study aims to investigate the physiochemical properties of the BFS powder based grout to determine whether it can be used as an environment-friendly grout material. As a fine powder, BSF can be used instead of cement grout due to its potential hydraulic property. BSF has also been known for its ability to strengthen materials long-term and to densify the internal structure of concrete. In order to investigate the physicochemical properties of the BFS powder based grout as a grout material, in this study assessment tests were performed through a gel-time measurement, uniaxial compressive strength, and chemical resistance tests, and heavy-metal leaching test. Characteristics and advantages of the slag were studied by comparing slag and cement in various methods.

This study is to discusses the relevance of social welfare in Freud's psychoanalytic theory. The results of the study are as follows. First, psychoanalytic theory details the client's family history and personal history to help them identify the characteristics of the problem they have today. At this time, social workers actively listen to clients and try to get various information.Second, when used in psychoanalytic techniques, the resistance of the client can be interpreted and analyzed to help the client maintain friendly relationships with the client.Third, psychoanalytic theory can properly apply the client's current state of mind by understanding the potential conflicts or emotions that exist in the client's unconscious mind. Fourth, during the process of intervention, social workers need to deal well with the client's transition response. This process allows social workers to observe the effect of reducing the stimuli that can cause nervousness in clients.In conclusion, all the techniques of interpretation used in psychoanalytic theory are, after all, techniques that help social workers improve clients' insight into their problems and help clients solve their psychological problems themselves. The psychoanalytic theory is widely applied in social welfare.

In the era of the 4th industrial revolution, smart factories have received great attention, where production and manufacturing technology and ICT converge. With the development of IoT technology and big data, automation of production systems has become possible. In the advanced manufacturing industry, production systems are subject to unscheduled performance degradation and downtime, and there is a demand to reduce safety risks by detecting and reparing potential errors as soon as possible. This study designs a model based on supervised and unsupervised learning for detecting anomalies. The accuracy of XGBoost, LightGBM, and CNN models was compared as a supervised learning analysis method. Through the evaluation index based on the confusion matrix, it was confirmed that LightGBM is most predictive (97%). In addition, as an unsupervised learning analysis method, MD, AE, and LSTM-AE models were constructed. Comparing three unsupervised learning analysis methods, the LSTM-AE model detected 75% of anomalies and showed the best performance. This study aims to contribute to the advancement of the smart factory by combining supervised and unsupervised learning techniques to accurately diagnose equipment failures and predict when abnormal situations occur, thereby laying the foundation for preemptive responses to abnormal situations. do.

The objective of this study was to optimize the mixing ratio of mixed bean protein concentrate (MBPC) and to improve the quality of sausage analogues. Soybean (Glycine max MERR), mung bean (Phaseolus radiatus L.), red bean [Vigna angularis (Wild.)], and pea (Pisum sativum L.) were mixed and processed to produce a MBPC, which was used to make a sausage analogue. The protein, moisture, and carbohydrate content were significantly (p<0.05) different among the samples. A significant (p<0.05) improvement was observed in textural properties (hardness, gumminess, and chewiness), cooking loss, frying loss, and emulsion stability of the sausage analogue. This study suggested the possibility of attaining high-quality sausage analogues and partial sausage analogues using MBPC, which could serve as a potential ingredient in meat analogues.

The Fourth Industrial Revolution brought the quantitative value of data across the industry and entered the era of 'Big Data'. This is due to both the rapid development of information & communication technology and the diversity & complexity of customer purchasing tendencies. An enterprise's core competence in the Big Data Era is to analyze and utilize the data to make strategic decisions for enterprise. However, most of traditional studies on Big Data have focused on technical issues and future potential values. In addition, these studies lacked interest in managing the quality and utilization levels of internal & external customer Big Data held by the entity. To overcome these shortages, this study attempted to derive influential factors by recognizing the quality management information systems and quality management of the internal & external Big Data. First of all, we conducted a survey of 204 executives & employees to determine whether Big Data quality management, Big Data utilization, and level management have a significant impact on corporate work efficiency & corporate management performance. For the study for this purpose, hypotheses were established, and their verifications were carried out. As a result of these studies, we found that the reasons that significantly affect corporate management performance are support from the management class, individual innovation, changes in the management environment, Big Data quality utilization metrics, and Big Data governance system.

Recently, Korea's cultural content industry is developing, and behind the growing recognition around the world is the real-time sharing service of global network users due to the development of science and technology. In particular, in the case of YouTube, its propagation power is fast and powerful in that everyone, not limited users, can become potential video providers. As more than 80% of mobile phone users are using YouTube in Korea, YouTube's information means that psychological factors of users are reflected. For example, information such as the number of video views, likes, and comments of a channel with a specific personality shows a measure of the channel's personality interest. This is highly related to the fact that information such as the frequency of keyword search on portal sites is closely related to the stock market economically and psychologically. Therefore, in this study, YouTube information from a representative entertainment company is collected through a crawling algorithm and analyzed for the causal relationship with major variables related to stock prices. This study is considered meaningful in that it conducted research by combining cultural content, IT, and financial fields in accordance with the era of the fourth industry.

Signs of the street and scenes of the nature(tree) popping up like a still screen in a monotonously repeated routine, as if waiting for something by chance, characters appearing and disappearing without special meaning, advise you to get away from cliché meetings and breakups while repeating it. The images of people returning to their places without presenting any conclusions highlights the coincidences and unexpectedness of everyday life, but are so familiar that it is easy to be overlooked, it brings us to experience the potential of everyday unfamiliarity in such moments. The actor's performance, which deviates from the practice of well-organized characters, is improvised (unplanned and uncoordinated) emphasized on the scene and expresses the everyday nature of his differentiated character freely like the reality as if he were locked up in a film structure but not confined to it, and as if he got used to the everyday life. Also the repeated words and actions of characters, and unpredictable changes of emotions, centered by the encounters and conversations of this film of Hong Sang-soo, everything that is presented in the background of everyday life in its form, let's us pay attention to the meaning and what to be found in the film. In addition, director Hong Sang-soo, who creates a story after selecting actors to reproduce this daily process in a realistic manner, sets new relationships between the characters and the actors, presenting a new method of realistic expression, through the actor who repeatedly appears in the film. This study analyzes the everyday characters and acting of the film based on director Hong Sang-soo's directing style.

Director Lee Chang-dong saying that the most important thing is to let the audience experience, find its meaning, interpret, and feel the pure sensation (whether it's image, sound or music) that the film has instead of narrative giving you the answers, through the film presenting the pure natural landscape as it is, but all the familiar things that can be taken as a riddle are conveyed in images, and all the elements that make up the film share its presence with each other and let us experience a mysterious weight of reality that cannot be defined through its strange symbolism and metaphors, and it reflects various human emotions, reflecting curiosity of reality, the words that are hardly spoken, meanings of life that we were not being aware of. Rather than having one definitive figure, through the character's personality expressing an imperfect character with a complex ambiguous behavior asks about the things that can't be explained logically and the fact of life that can't be divided into truth or lie. Also, the acting approaches emotionally and primitively rather than using artificial expressions, showing the invisible elements of emotions that are latent inside humans through temperate acting style, leads the audience to distant themselves and reflect more deeply into life. This study analyzed the characters and acting of the film based on director Lee Chang-dong's directing style.

The hybrid phenomenon of pronunciation of K-Pop lyrics, which is the diction fusion phenomenon of lyrics, is not a strategic measure for an overseas expansion but a natural formation in the course of history of K-Pop. With the debut of Seo Tai-ji and Boys in 1992, the course of K-Pop changed and settled from ballad to dance music. After three years, the success of a hip hop dance music, 'Come Back Home', opened up a door to Korean Americans who ascertained the potential competitiveness of a hip hop music in K-Pop market. And the writer insists that such advance of Korean Americans into K-Pop market is the origin of the bilingual usage and diction fusion phenomenon of K-Pop lyrics. Therefore, this research will look into the pronunciation system of Korean and English in order to understand the bilingual pronunciation system shown in the lyrics sung by Korean American hip hop singers in the 1990s. Moreover, through Korean pronunciation system, this analysis will discover the main cause of continual acceptance and application of Korean American's broken Korean in the diction of lyrics. Last but not least, this exploration will show the correlation of English pronunciation method of Korean lyrics appeared in K-Pop and the diction of Korean lyrics used by Korean American hip hop singers in late 90s. This research will identify the primary cause of the diction fusion phenomenon in the course of history of K-Pop.
