지식을 관리하는 것에 주력했던 기존의 인공지능 연구 방향은 동적으로 움직이는 외부 환경에서 적응할 수 있는 시스템 구축으로 변화하고 있다. 이러한 시스템의 기본 능력을 이루는 많은 학습방법 중에서 비교적 최근에 제시된 강화학습은 일반적인 사례에 적용하기 쉽고 동적인 환경에서 뛰어난 적응 능력을 보여주었다. 이런 장점을 바탕으로 강화학습은 에이전트 연구에 많이 사용되고 있다. 하지만, 현재까지 연구결과는 강화학습으로 구축된 에이전트로 해결할 수 있는 작업의 난이도에 한계가 있음을 보이고 있다. 특히, 복수의 부분 작업으로 구성되어 있는 작업을 처리할 경우에 기본의 강화학습 방법은 문제 해결에 한계를 보여주고 있다. 본 논문에서는 복수의 부분 작업으로 구성된 작업이 왜 처리하기 힘든가를 분석하고, 이런 문제를 처리할 수 있는 방안을 제안한다. 본 논문에서 제안하고 있는 EQ-Learning의 강화학습 방법의 대표적인 Q-Learning을 확장시켜 문제를 해결한다. 이 방법은 각각의 부분 작업 해결 방안을 학습시키고 그 학습 결과들의 적절한 순서를 찾아내 전체 작업을 해결한다. EQ-Learning의 타당성을 검증하기 위해 격자 공간에서 복수의 부분작업으로 구성된 미로 문제를 통하여 실험하였다.

우리나라 선원은 해방기 이후 외화가득의 주역이며 비상시 군수물자를 운송할 수 있는 사회경제적으로 가치 있는 직업이나 최근 선원 직업의 사회적 인식이 다소 부정적이고, 예전처럼 젊은 선원의 유입이 높지 않은 편이다. 본 연구는 일반 대중을 대상으로 Q 방법론을 활용하여 선원의 직업을 어떻게 인식하는지 그 이미지 유형과 특성을 분석하였다. Q 방법론에 의한 선원 직업 이미지 인식은 3개 유형으로 분류되었고 우리나라 선원에 대한 대중의 인식은 부정적이였다. 이러한 연구 결과를 바탕으로 해운산업의 핵심 인적자원인 선원의 안정적으로 확보하고 선원 종사자들의 직업적 만족도와 취업률을 높이기 위해서는 대중들이 인식한 선원의 부정적 직업 이미지를 전환할 수 있는 다양한 방안을 마련해야 할 것이다.

The purpose of the study was to identify the untact medical services campaign awareness in COVID-19 era using Q methodology. We used subjective analysis for this purpose and examined 1) what are the types of untact medical services campaign awareness? and 2) what are the homogeneous characteristics and implications between each type? We composed a Q concourse through interviews with university students to write Q statements, selected a P sample, and used Q-sort obtained from the sorting process to analyze it through Q-factor analysis in the PC QUANL program. Q methodology was used to examine the subjective tendency of untact medical services campaign awareness in COVID-19 era. As a result of the analysis, four types were identified. 1) Type 1 (N=7): Belief & official announcement type, 2) Type 2 (N=4): Governmental notice type, 3) Type 3 (N=3): Medical information public notice type, 4) Type 4 (N=2): Sympathetic information type. An insightful analysis was derived in that the analysis could identify factors in the schema of respondents related to untact medical services in COVID-19 era.

The purpose of this study is to find out subjective perception types and needs of interested group on manpower training system with long-term care service by Q methodology, then to search for political measures to improve long-term care system in the implication of the sorted subjective perception types. The result of the study showed that there are five major sorts of subjectivities on manpower training system with long-term care service: emphasizes retraining of existing care worker(Type1), emphasizes ethics of public service provider(Type2), emphasizes practice-oriented education(Type3), emphasizes policy judgement of government(Type4), emphasizes training of long-term care worker in demand(Type5). And to try quantity approach methods, this study was developed Q-Block as a assessment tool to enhance validity and reliability of Q-types. The results of the survey showed high conformity.

The purpose of this study is to explore the present US consumer behavioral trends and various cognitive schema types for sharing economy frame and shared service. For this, by applying Q methodology, this paper theoretically defines three differentiated typologies of US consumer in a interpretive perspective. This study is in-depth focused on discovering and categorizing characteristics of a respondent's thinking structure called 'schemata'. According to the entire procedures of Q methodology, this paper analyzed Q-sorted data from twenty-four people in the basis of forty Q-samples (statements). Consequently, we discovered four consumer groups named as Type 1 'Socialsumer', Type 2 'Smarsumer', Type 3 'Researsumer'.

The purpose of this study was to analyze the recognition of secondary pre-physical education teachers' recognition for the learning athletics using Q methodology. P-sample was composed of 28 pre-secondary P·E teachers. The selected Q samples were arranged in the normal distribution form. The collected data were analyzed by factor analysis through varimax rotation using QUANL PC program. This study found four types of recognition on learning athletics. Type I is defined 'the type of recognition for education value.' Type II is defined 'the type of emphasizing assistant activities.' Type III is defined 'the type of an appeal difficulty to learn athletics skill.' Type IV is defined 'the type of emphasizing the basic movement value.' Based of the results of this study, the implications and direction to future research on athletics activities are suggested.

This study applied Q methodology to consumers who have experience using food trucks to understand subjective perception of food truck customers. The purpose of this study is to characterize the perceptual structure of food truck customers, to describe characteristics of the types and to suggest some implications. The results of the type analysis are as follows. The first type (N = 10): Food truck zone accessibility preferred type, the second type (N = 8): Complex entertainment experience type, the third type (N = 9) = 3): Fast food preference type. Future research on food trucks, restaurants, and tourism will be based on a variety of literature and empirical studies, and will be revised and supplemented with more detailed Q methodological questions and analytical techniques to analyze the various opinions of respondents in a more concrete and objective manner.

With the recent development of AI and ICT, autonomous vehicles are becoming a reality, and sales of the vehicles equipped with partial autonomous driving technology are also rapidly expanding. In this situation, technology research on autonomous vehicles has been actively conducted, but research on exploring the perception of autonomous vehicles from the user's perspective is relatively insufficient. Therefore, this study categorizes autonomous vehicle users into four types - , , , and . Then, it examines the characteristics of each type. For this purpose, we applied Q-methodology, a qualitative research method, to observe self-referent subjectivity of 32 P-samples using a Q-sample which consists of 34 statements. The results of our study have significance in that they provide domestic and global automakers with strategic directions for technological development and market expansion of autonomous vehicles, and academically provide hypotheses for subsequent quantitative research.

The purpose of this study was to identify the types of subjectivity on communication styles of nursing freshmen and explore their properties by using the Q Methodology. Fifty nursing freshmen of P sample classified 55 Q-statements into the normal distribution of 11 point scale. Data were collected from May to June, 2015 and analyzed by using PC-QUANL program. As a result, communication styles are identified as 'Open-interaction facilitator', 'Other-considerate listener', 'Tense-sensitive to criticism person', and 'Non-interactive observer'. Open-interaction facilitators proficiently use verbal and nonverbal expressions, openly disclosing themselves and facilitating interactions with others. Other-considerate listeners primarily consider others before themselves, with careful communication. Tense-sensitive to criticism persons are nervous, sensitive to criticism, and are distractive style, so they have difficulties in intimate interaction with others. Non-interactive observers are bystanders who observe others and feel indifferent to interactions, without any self disclosure. The result of this study will be used for developing communication educational programs for nursing freshmen.
