The purpose of this study was to analyze undergraduate students' reasoning for solving a problem about a rock and investigate the roles and importance of critical evidence (CE) and critical resource models (CRMs) in abductive reasoning. Participants were 20 senior undergraduate students enrolled in a science major course in a university of education. They were asked to abductively infer geologic processes of sedimentary rocks having a lot of holes and represent them with models. Their reasoning were analyzed according to a scheme for modeling-based abductive reasoning. As a result, successful student reasoning was characterized by using a diversity of grains and lots of holes as CE, activating the sedimentary rock formation and weathering as CRMs, and combining the CRMs into a scientifically sound explanatory model (SSEM). By contrast, in the reasoning unsuccessful in proposing a SSEM, students activated the igneous rock (basalt) formation and deposition as resource models (RMs) based on the evidence of the holes in the rocks and diverse grains, respectively, and used the RMs to construct their own explanatory models (EMs). It was suggested that to construct SSEMs to solve earth scientific problems about rocks, students need to know what could be CE in a particular problem situation, take an integrative or systemic approach to a rock problem, use multiple RMs, and evaluate RMs or EMs in light of evidence.

The purpose of this study was to identify structural patterns in the subjectivity of Taegyo in pregnant woman and to provide a basis for nursing interventions. Thirty pregrant women were the subjects of this study. They were in the gestation period of pregnancy between 12 weeks to five days post partum and they lived in the city of Taejon. The research method employed Q-methodology which is based on self-psychology and abductive logics. The results revealed three different types of the Taegyo ; 1) Peaceful mind type, listening to music and appreciation of art for quietness of mind and also the support and concern of husband. 2) Self control type, recognizes herself as a pregrant woman and trys to do her works spontaneously and also adapt herself to changing of circumstances. 3) Dependent oriented type, needs absolute help from the surroundings under the specific condition of pregnancy. This results show that investigating the specific experience, characteristic and structure of the Taegyo of a pregnant woman can be used as a part of the nursing assessment and also provides useful basic data of nursing interventions during pregnancy.

The purpose of this study was to examine the understanding and perception of 'community welfare', a domain of social welfare. First of all, we used the Q methodology, a qualitative research, to typology the recognition of community welfare. For the analysis, we have obtained various terms (Q samples) that have been discussed and learned in the community welfare, and examined the types of recognition of these terms. For the analysis, 29 samples of 29 samples were obtained from 29 samples of P samples. As a result of analysis, three types were defined. In other words, emphasizes 'participation of residents', 'building ties', and 'improvement of life quality of residents' is named it "Quality of residents life-Relationship Type". emphasizes 'improvement of quality of life of residents' and 'satisfaction of community needs' and named it "Quality of residents life- Desire for community needs Type". emphasizes 'participation of residents' and 'improvement of quality of life of residents' and named it "Participation of Residents-Quality of Life Type". The respondents' characteristics according to type, it was found that there was a difference in recognition of community welfare by individual characteristics. So, we hope to enhance the usefulness of the hypothesis abductive approach and to extend the study to future quantitative research.

This study attempted to examine how we really think about our daily duties, work, and labor, and what it means. In particular, in this study, using the Q-methodology, one of the "qualitative studies," diagnosed and categorized general workers' thoughts about their work and labor. Accordingly, the following analysis results were derived. First, as a result of the analysis, three types were derived, and the types were named as follows based on the Q statement emphasized by each type. emphasizes statements such as 'blessing/happiness', 'rest', 'lover', and 'reward' for work, and labor was named 「Positive Type」. was named as 「Negative Type」 because statements such as 'painfulness', 'the beginning of the day', 'duty', and 'war' were emphasized. In , 'colleagues and friends' and 'learning' were positive, and 'beginning of the day', 'duty', and 'rest' were expressed as negative statements, so it was named as 「Positive Neutral Type」. 'Work' and 'labor', which are indispensable beings in our daily life, are blessings that must be done, happiness, and co-workers and friends, but the value of their existence is possible when appropriate 'resting' is assumed. In addition, Q methodology is expected to be confirmed as an empirical study in the future, as well as usefulness as a hypothesis abductive approach.

We investigate a logical approach to represent medical knowledge, reason deductively and diagnostically. It is suggested that medical knowledge-bases can be formulated as a set of sentences stated in classical logic where each sentence reflects a doctor's knowledge about the human anatomy or his/her view of patient's symptoms. It is also suggested that a form of temporal reasoning can be captured within the same framework because each sentence can have a different truth value based on time. We apply our logical framework to formalize diagnostic reasoning, where the primary cause of illness is chosen among the set of minimal causation on the basis of abductive hypotheses. Most of our examples are given in the context of medical expert systems.

Most human behaviors are based on self-perceptual image. Subjectivity in professional nursing image is shown in their opinions, beliefs, values, and attitudes of professional nursing and it helps to understand individual's behavior. This study was initiated to find the characteristics and patterns in subjectivity of hospital nurses' professional nursing image. The Data were collected from Apr. 20 to Aug. 22, 1996. The research method employed Q-methodology which is based on self-psychology and abductive logics. Analysis of Q-type obtained by QUANL pc program. The characteristics of professional nursing image was analyzed based on the typal array, extreme comments, and the subject's demographic information. The results revealed that there are three different types on the professional nursing image. The three types were named as follows : The first type, the Improvable, consisting of 6 subjects, preferentially perceived nursing is human behavior as life process, coordinating with other health personnel for the patients as nurses' important role. On the other hand, they are taking a little dissatisfied view of professional nursing image, which can be estimated to advance for the construction of the professional nursing image. The second type, the Self-conflicted, consisting of 13 subjects, who have the subjectivity of the image by focusing on external and environmental factors rather than developing positive individual nurses' image for their profession. They have very conflic-ting and self-degrading traits. The third type, the Affirmative, consisting of 10 subjects, who appreciate the essence of nursing, and that they highly perceived nurse' positive attitude, devotion, mature interrelationship and self-developing efforts etc. In conclusion, this study discovers three types on the professional nursing image and their relationship. By identifying the nature of three types, this study suggests that the results should be useful reinforcement tool in educating nursing students as well as in continuing education for hospital nurses.

Facebook has quickly infused across cultures worldwide to become a common household term for diverse spectra of netizens, especially youngsters. Inherently, interactive in nature, Facebook provides a common cyber enabled platform for online interactions with social friends, living across the world. However, despite its merits, users also experience certain disadvantages, which include but are not limited to rise in feelings of social comparison, decline in self-esteem, contentment and general subjective well-being. This work aims to determine the role of Facebook in spreading envy and identify factors that trigger such emotions. Due to abductive nature of the study, we used pilot interviews and consulted relevant literature to formulate hypotheses. Further, we used deductive approach and conducted a survey. The results showed that frequent use of Facebook, particularly passive following is main predictor of envy, and social interaction is the biggest cause for development of envious feelings in Facebook users. However, insignificant variation was found while investigating relationship between envy and factors, such as pretentiousness, time spent, accomplishment, everything in life, likes on posts, popularity across genders, marital status and genre.

This study identified the linguistic features of Earth science treatises through the analysis of the register. Data included three Korean treatises that were in geology, atmospheric science, and oceanography. The register of Earth science treatise was as follows: First, there were semantic, referential connections between Themes and Rhemes, that the messages and main points of the texts were expressed coherently and cohesively. Second, some predicates were used which were related to deductive inference, abductive inferences, or causal relation according to the genre elements of each text. The logical relations were not represented by the conjunctions but by the types of predicates. Third, most texts in the treatises showed interpersonally weak relationship using mental predicates related to possibilities, which meant scientists expressed indirectly their interpretation, explanation, or arguments. From these results, we argued that some activities of unpacking the language of science be included in science curriculum in order to improve students' literacy of science texts and understanding scientists' knowledge construction.
