Sentiment analysis, a branch of natural language processing that classifies and identifies subjective opinions and emotions in text documents as positive or negative, can be used for various promotions and services through customer preference analysis. To this end, recent research has been conducted utilizing various techniques in machine learning and deep learning. In this study, we propose an optimal language model by comparing the accuracy of sentiment analysis for movie, product, and game reviews using existing RNN-based models and recent Transformer-based language models. In our experiments, LMKorBERT and GPT3 showed relatively good accuracy among the models pre-trained on the Korean corpus.

뉴스 헤드라인에 제3자의 발언을 직접 인용해 전언하는 이른바 '따옴표 저널리즘'이 언론 보도의 객관주의 원칙을 해치는지는 언론학 및 뉴스 구독자에게 중요한 문제이다. 이 연구는 온라인 포털사이트를 통해 실시간 유통되는 한국어 기사의 정확성을 판별하기 위한 기계학습(Machine Learning) 모델을 제안한다. 이 연구에서 제안하는 모델은 Edit Distance와 FastText 기법을 활용해 기사 제목과 본문 내 인용구의 유사성을 측정하고, XGBoost 모델을 활용해 최종 분류한다. 아울러 이 모델을 통해 229만 건의 뉴스 헤드라인에 대해 직접 인용구가 포함된 기사가 취재원의 발언을 주관적인 윤색없이 독자들에게 전하고 있는지를 판별했다. 이뿐만 아니라 딥러닝 기반의 KoELECTRA 모델을 활용해 기사의 제목 내 인용구에 대한 감성 분석을 진행했다. 분석 결과, 윤색이 가미되지 않은 직접 인용형 기사의 비율이 지난 20년 동안 10% 이상 증가했으며, 기사 제목의 인용구에 나타나는 감정은 부정 감성이 긍정 감성의 2.8배 정도로 우세했다. 이러한 시도는 앞으로 계산사회과학 방법론과 빅데이터에 기반한 언론 보도의 평가 및 개선에 도움을 주리라 기대한다.

This study was carried out to investigate a usefulness of the microsatellite DNA markers for individual identification and parentage verification in three dog breeds. A total of 59 random dog (31 Chiwawa, 20 Poongsan, 8 Labrador Retriever) samples were genotyped by using 14 markers (Chiwawa dog), 16 markers (Poongsan dog), and 12 markers (Labrador Retriever dog) among the 17 international standard markers (PEZ1, 3, 5, 6, 8, 10, 11, 12, 13, 15, 16, 17, 20, 21, FHC2010, FHC2054 and FHC2079), respectively. The number of alleles per locus varied from 4 to 14 with a mean value of 6.07 in Chiwawa dog, 2 to 9 with a mean of 4.75 in Poongsan dog, and 3 to 5 with a mean of 4.00 in Labrador Retriever dog. Observed heterozygosity was ranged 0.419${\sim}$0.968 (mean 0.755), 0.300${\sim}$0.950 (mean 0.597) and 0.125${\sim}$0.750 (mean 0.604), and expected heterozygosity was ranged 0.432${\sim}$0.883 (mean 0.711), 0.262${\sim}$0.817 (mean 0.559) and 0.425${\sim}$0.808 (mean 0.660) in these three dog breeds. PIC value was ranged 0.397${\sim}$0.856 (mean 0.659), 0.222${\sim}$0.772 (mean 0.503) and 0.354${\sim}$0.717 (mean 0.563) in these three dog breeds. Of the 17 markers, PEZ1, PEZ3, PEZ6, PEZ10, PEZ12 loci, PEZ1, PEZ6, PEZ13 loci, and PEZ8, PEZ12 loci have relatively high PIC value (＞0.7) in Chiwawa dog, Poongsan dog and Labrador Retriever dog, respectively. The exclusion probability was ranged 0.240${\sim}$0.741, 0.111${\sim}$0.616, and 0.198${\sim}$0.529, and the combination of microsatellite loci was 0.9999, 0.9991, and 0.9968 in Chiwawa dog, Poongsan dog and Labrador Retriever dog, respectively. These results can give basic information for developing parentage verification and individual identification system in these three dog breeds.

This study examines the perception and trust of Korean society and people among students and adults using the indigenous psychological analysis. A matched sample of 1,107 participants, consisting of 369 students, their mothers and their fathers completed a questionnaire developed by the present researchers. The results indicate that parents more likely than adolescents to hold negative views of Korean society. Adults are more likely than adolescents to view Korean society as showing high ingroup favoritism, to be insecure, to be conservative, to be corrupt, and to have social inequities. Both groups agree that Korean society is not rational nor democratic, but believe that it has the potential for progress. Second, parents are more likely to hold negative views about Korean people. Adults are more likely than adolescents of viewing Korean people as overly conscious about social face, emotional, selfish, exclusionary, and conceited. Both adolescents and their parents agree that Koreans are cooperative, full of jung (deep affection and attachment), and sincere. Third, adults are less likely to trust Korean institutions than adolescents. Adults are less likely than adolescents to trust National Assembly, political parties, and unions. Adolescents are more likely than their parents to trust family members, school friends, teachers, and government employees. These results indicate that adolescents have higher trust of Korean society and people than their parents. Fifth, the overall results indicate that both group perceive Korean society as showing high ingroup favoritism and corruption. In terms of Korean people, respondents had a more balanced view of perceiving them as highly sensitive to social face and being emotional, while also perceiving them as cooperative and full of jung. The trust of Korean institutions were generally low, especially the National Assembly and political parties. However, the trust of family was very high, followed by trust of school friends and teachers. The trust of government employees was low and this was especially the case for politicians.

The purpose of this is to make sure what the scholar of the Choseon thought the object of aesthetics, and which psychological element did they use to clear the center of the aesthetics. In addition, I consider their way to recognize the human's aesthetic point of view. A literary man in Choseon regarded the five senses as an obstacle which interrupted to see the nature of all things. So they set up the spiritual condition as their aesthetic subject, with suppressing the pleasure through five senses. The goal to make one's mind calm was to cause someone's spirit to activate freely. The condition of the calmness was considered as a process of recovering the human's natural spirit, which was connected to the poetic spirit and became the aesthetic subject. Simultaneously, a literary man at that time set up the condition of the calmness as a subject of objective consciousness, and estimated the common things as a objective existence, which led to the result that all the materials of the poem and the poet could be unified. This aesthetic centra put a premium on the senses caused by contacting with all natural things, and adopted the 'Xing' as a method of expression. This 'Xing' is not a sense based upon one's experience, but a sense which is created of itself. The expression method of 'Xing' caused the reader to feel and express, encourage, and sublimate what they feel through the poem, as well as purified reader's mind.

Satisfaction on the residential environment is a major factor influencing the choice of residence and migration, and is directly related to the quality of life in the city. As online services of real estate increases, people's evaluation on the residential environment can be easily checked and it is possible to analyze their satisfaction and its determining factors based on their evaluation. This means that a larger amount of evaluation can be used more efficiently than previously used methods such as surveys. This study analyzed the residential environment reviews of about 30,000 apartment residents collected from 'Zigbang', an online real estate service in Seoul. The apartment review of Zigbang consists of an evaluation grade on a 5-point scale and the evaluation content directly described by the dweller. At first, this study labeled apartment reviews as positive and negative based on the scores of recommended reviews that include comprehensive evaluation about apartment. Next, to classify them automatically, developed a model by using Bidirectional Encoder Representations from Transformers(BERT), a deep learning-based natural language processing model. After that, by using SHapley Additive exPlanation(SHAP), extract word tokens that play an important role in the classification of reviews, to derive determining factors of the evaluation of the residential environment. Furthermore, by analyzing related keywords using Word2Vec, priority considerations for improving satisfaction on the residential environment were suggested. This study is meaningful that suggested a model that automatically classifies satisfaction on the residential environment into positive and negative by using apartment review big data and deep learning, which are qualitative evaluation data of residents, so that it's determining factors were derived. The result of analysis can be used as elementary data for improving the satisfaction on the residential environment, and can be used in the future evaluation of the residential environment near the apartment complex, and the design and evaluation of new complexes and infrastructure.

Yeon Sang-Ho's Animation occupies an exceptional place in Korean Animation, being categorized as the kind of realism representing the pitiable actuality rather than the liberal and creative imagination. His animation appreciated as 'stories much more real than the reality' mainly depicts the world of 'the others' who resides on the periphery of the society in a rough and straightforward way. Yeon Sang-Ho's Animation represents the emotions and desire of characters as well as the heartless real world refusing the fantasy, through which it reflects the portraits of people living in post-capitalistic era seen from the microscopic view. This article investigates the textual characteristics, defining his animation as the Brutal history of 'The Others'. Two conditions which constitute the actual world in his works are the absurd social system and the characters who are afflicted with the trauma, belonging to the lower classes. Therefore, the landscape of real life which contains vicious victim, corrupted monster and being as 'homo sacer' looks like a painting of hell. Yeon Sang-Ho's Animation summons the shadow of ourselves which has been negated or neglected through the figure of 'the others' produced in post-capitalistic era and exposes our bare face and the uncomfortable truth by displaying the affected area of out society plainly. Furthermore, his works demonstrate the possibility of Korean animation as a representational language of facing the reality and searching for the truth.

In the eighteenth century, the scottish philosophers Francis Hutcheson, David Hume and Adam Smith share the idea that morality comes from moral sense, which is a feeling of approval or disapproval of agent's motive and action. However, they have the different views in explaining the mechanism that generates the moral sentiments. Hutcheson takes a moral sense to be a unique mental faculty that is innate to all humans, and regards it as being guaranteed by supernatural apparatus like divine Providence. Hume and Smith reject Hutcheson's concept of internal moral sense and take a stage further Hutcheson's projects of internalisation by naturalizing morality in terms of the principle of sympathy. It is widely held that Hume's moral sentimentalism is essentially similar to Adam Smith's. Though there are important points of contact between Smith's account of sympathy and Hume's, the differences are considerable. The chief of them lies in the fact that Hume grounds our approval of virtue on our recognition of its utility and convention, and Smith does not. Smith grounds our approval of virtue on the impartial spectator's judgment, i.e., conscience. Hence for Smith, the impartial spectator is the one that bridges the gap between particularity and universality and works the vehicle of practical reason. Given this, in this paper, first, I will clarify the difference between Hume's and Adam Smith's understandings of sympathy. Second, I will elucidate how they explain the process to produce the moral sentiments based on their understandings of sympathy. I shall finally explicate in what way Hume's and Smith's theories on sympathy work as moral normativity.

The purpose of this study was to conduct pan play counseling that contains Korean cultural characteristics to see if it affects college students' anxiety reduction in coronavirus situations. Counseling was conducted for 40 minutes once a week. The associations of participants were recorded for each session. The score of anxiety test decreased in the participants' pre-and post-anxiety tests. The effectiveness of pan play counseling was verified. Case analysis applied phenomenological research method. Structural decisions through case analysis were in the order of regression, expression, differentiation, and integration. In the results of case analysis, participants feel confused through encounters in the early stages and regress unconsciously. Emotions of negativity that could not be erupted in the expression structure appear as consciousness, and the participants awaken. Participants expressed emotions such as fear, anxiety, loneliness, anger, and irritation. Consciousness of the unconscious causes a transformation of ego. The ego gains discernment as the great drama emerges from the differentiated structure. In other words, it builds confidence. The goal of counseling is to reinforce the ego, realizing the potential to overcome anxiety. In the last integration's structure, a wedding, a baby, and a old wise man appeared, showing that a transformation took place. In the results of this study, it was verified that pan play counseling has a healing effect. This study is expected to serve as an opportunity to develop Korean counseling techniques that incorporate Korean culture.
