This essay will consider evolutionary views that attempt to capture the continuity of theory-change from Newtonian to Einsteinian physics via the formal aspects of these theories. Although it cannot be denied that the formal aspects such as 'correspondence principles' and 'covariance principles' provide important information concerning this theory-change, these formal properties are not sufficient to capture the essential elements of any evolutionary account of the development of Einstein's special and general theories of relativity from Newtonian mechanics.

This study aims to investigate how religious orientation of college students and the religious fundamentalism are related to their subjective well-being, and the interaction of religious orientations and the religious fundamentalism on their well-being. The participants were 374 college students who studies at an university located in Seoul, whose average of age were 22.54 (SD=4.79). The psychological tests used in this research included the following: I/E-R, the Religious Fundamentalism Scale, the Spiritual Well-Being Scale, Emotion Frequency Test, Satisfaction with Life Scale, Subjective Happiness Scale, Life Satisfaction Motivation Scale, and Life Satisfaction Expectancy Scale. Although religious students experienced more religious well-being than non-religious students, their subjective well-being were not higher than those of non-religious students. Results reveal that religious orientations were positively related to subjective well-being such as life satisfaction, subjective happiness, and positive emotions, as well as spiritual well-being. However, those covariance was approximately 4~6% only. Religious fundamentalism was also positively related to spiritual well-being and life satisfaction, it was negatively related to the motivation to live though. On the other hand, moderate effects of the religious fundamentalism on the relations of religious orientations to most of subjective well-being variables. Results of simple main effect analyses indicated that the students who were strongly oriented toward religion with higher religious fundamentalism showed significantly higher existential well-being, positive emotions, life satisfaction, subjective happiness, and especially their motivation and expectation for future life, whereas there were no significant differences in subjective well-being of students with lower religious fundamentalism by religious orientation. This finding suggests that some religiosity variables could affect human well-being with interactions

In this paper, we investigate cosponsorship networks found in the 17th National Assembly of Republic of Korea. New legislation should be sponsored by at least 10 legislators including one main sponsor. Cosponsorship networks can be constructed, using directional links from cosponsors of legislation to its main sponsor; subsequently, these networks indicate the social relationships among the legislators. We apply Exponential Random Graph Model (ERGM) for valued networks to capture structural properties and the covariate effects of networks. We find the effect of the same party has the greatest influence on the composition of the network. Mutuality also plays an important role in the cosponsorship network; in addition, the effect of the number of elections won by a legislator has a small but significant influence.

This study investigated the effects of contiguity and reading mode on cognitive load factors measured by Galvanic Skin Response(GSR). In this study two experimental conditions were imposed to participants to measure cognitive load with the high contiguity picture and low contiguity picture. Thirty-four college students participated to this experiment(experiment group=17, control group=17), and spilt-plot factorial design was applied to control individual difference in galvanic skin response. Tasks of this experiment were reading and summary. The dependent variables were skin conductance response, and perceived difficulty. The independent variables were the degree of contiguity of visual material(high contiguity vs. low contiguity). The major result of this study was identification of a significant difference of GSR with low contiguity condition. Indeed it was identified that more complex reading condition required more cognitive loads. This finding supported that different cognitive process might require different amounts of cognitive loads. For the further research, this study discussed the validity of applying physiological signals to assess cognitive loads and relationships the associated affective reactions.

This study was performed to evaluate the characteristics of smoking behavior and the effects of smoking on clinical symptoms and level of serum prolactin in schizophrenic patients. Methods : 76 male schizophrenic patients answered the questionnaire about the characteristics of smoking patterns. And patients were assessed by brief psychiatric rating scale(BPRS), positive and negative syndrome scle(PANSS), Hamilton rating scale for depression(HAM-D), assessment for involuntary movement scale(AIMS) and symptom checklist 90 R(SCL-90-R). Serum prolactin levels were measured by enzymeimmunoassay. Results: 1) The frequences of drinking coffee were significantly higher in smokers. The reasons for smoking were to relieve tension, to avoid boredom, due to habit and to do with friends. 80.1% of smokers tried quitting, but smoking was relapsed due to craving and withdrawal symptoms. 2) No significant difference was seen in mean neuropeltic doses, scores of PANSS and AIMS. But as for BPRS, scores of anxiety/depression subscale were significanly lower in smokers. Scores of HAM-D and scores of interpersonal sensitivity and phobia among SCL-90-R were significantly lower. 3) Levels of serum prolactin were significanlty lower in smokers. Conclusion : These findings suggest that in schisophrenia smoking relieves anxiety and depression subjectively But decreased prolactin levels may suggest that the possibility of increased dopamine in CNS.
