  • This study examined changes of elementary school students' knowledge and attitudes toward AIDS after AIDS health educational programs were conducted. The experiment was executed from November the 28th, 2001 to February the 6th, 2002. Study examinees were 156 fifth year students of 2 elementary schools located at S City. A preliminary inspection was implemented. The post-examination was conducted by a questionnaire survey 2 weeks and 9 weeks after the program was finished. The measurement instrument was the questionnaire developed by Yun, Hyun Sik(1997) and modified by this researcher. Collected data were analyzed with SPSS program package, $x^2$-test and t-test, Repeated Measure ANOVA. Findings of study are as follows; 1. Hypothesis 1 ; the hypothesis 1 is "The points of AIDS knowledge are different at each moment, before conducting the educational program, 2 weeks after conducting the educational program, and 9 weeks after conducting the educational program". After the above hypothesis was examined, interactive actions were shown among different periods in both groups (F=267.241, p=.000), so that this hypothesis 1 was approved. 2. Hypothesis 2 ; the hypothesis 2 is "The points of attitudes toward AIDS are different at each moment, before conducting the educational program, 2 weeks after conducting the educational program, and 9 weeks after conducting the educational program". It was closely examined, and the findings are that significant differences between two groups were found, whereas any interactions were not shown between two groups(F=3.753, p=.055), after controlling the attitude scores that showed differences before the education by covariable, and examining the results. so that this hypothesis 2 was rejected. The above study tells that the AIDS health education for elementary school students made their knowledge and attitudes change significantly, but the education was not effective for changing students' attitudes. Elementary school students need more systematic and continual AIDS health education.

  • About a centry passed since christianity had been transmitted to our country. Now that christians outnumbers 5 millions. Christian home education are supposed to have exerted great influenced on the personality nature of children. Therefore, this study is aimed at determing the difference between the christian family and non-christian family in view of the personality development of children. Do it explain in detail : 1. To analize the development of children's personality nature. 2. To know the difference of development of the children's personality nature between christian and non-christian family. 3. To find out an educational means to programs the desirable personality nature of children. This research worker established bypothesis for getting above purpose as follows. Hypothesis A. Is there any difference in the personality development between the children of christian and non-christian family. hypothesis B. Development of personality nature will have a gab according to sex. To this end research worker carried out personality test around 200 persons on 4th grades of primary school. The result is as follows ; Hypothesis A-there will be difference in the personality development between the children of christian family and non christian family. The children of christian family showed higher development of reflectiveness as A, 1 emotional stability and reflectiveness as A , 2, emotional stability as A, 3 then the children of non christian family, and mostly is showed a little of fifference, so this hypothesis was denied. Hypothesis B-there will be difference in the personality development between man's and women's group. In this hypothesis boys chowd higher development of general activity and domonance as B, 1, general activity and dominance and impulsiveness as B, 2, activity and dominance and emotional activity and impulsi veness as B, 3, then girls so this hypothesis was accepted.

  • This study aimed to redefine the concept of fishing village tourism. In addition, it aimed to carry out detailed analyses of the influences of authenticity and non-authenticity of fishing village experience on tourist's satisfaction as well as the influences of tourist's experience on their satisfaction. The study evaluated responses of people who visited research target fishing villages in the East sea area(Hwasung-si Baegmi-ri) which had been rated as successful case. The evaluation was performed to analyze how tourist satisfaction would be influenced by the authenticity of the fishing village experience program based on the authenticity theory(Wang, 1999) and the experience realms theory(Pine & Gilmore, 1999). This study tried to find out realistic factors of the experience realms theory through field investigation, conducting interviews, and holding discussions. From these, the cause-and-effect structure of authenticity, tourism experience and satisfaction could be identified. The results of hypothesis tests are as follows; With respect to the relationship between authenticity and satisfaction in hypothesis I, authenticity did not have a statistically significant effect on satisfaction, while non-authenticity had a significant influence. As a result, the research hypothesis I that authenticity influences satisfaction was partially supported. Regarding hypothesis II of the link between authenticity and tourism experience, a significant effect of authenticity was found in education experience, entertainment experience for Baegmi-ri village. The effect of non-authenticity was significant on deviation experience. Consequently, hypothesis II was also partly supported. The relationship between tourism experience and satisfaction in hypothesis III was significant in education, entertainment, and deviation experiences which lends support to hypothesis III to some extent.

  • Hypothesis is defined as a proposition intended as a possible explanation for an observed phenomenon. The purpose of this study was to generate a grounded theory on the process of undergraduate students' generating hypothesis-knowledge about scientific episodes. Three hypothesis-generating tasks were administered to four college students majored in science education. The present study showed that college students represented five types of intermediate knowledge in the process of hypothesis generation, such as question situation, hypothetical explicans, experienced situation, causal explicans, and final hypothetical knowledge. Furthermore, students used six types of thinking methods, such as searching knowledges, comparing a question situation and an experienced situation, borrowing explicans, combining explicans, selecting an explican, and confirming explicans. In addition, hypothesis-generating process involves inductive and deductive reasoning as well as abductive reasoning. This study also discusses the implications of these findings for teaching and evaluating in science education.

  • This paper tests the stigma hypothesis and administration hypothesis on the illegal take-up group and non take-up group in the National Livelihood Security Program. A set of survey data, using multinomial logistic model, was analyzed for this purpose. Compared with the legal take-up group, the feature of illegal take-up group which has more workable household supports the administration hypothesis - the low skill of means-test office would increase the possibility of benefit fraud. The features of non take-up group support both the stigma hypothesis - the stigma prevents eligible person from participating in the social assistance program, and the administration hypothesis - the administration office is apt to make error to deny the eligibility of person who has supposed family supporters.

  • The ability hypothesis about black-and-white Mary once enjoyed the status of the "received view." But its popularity has declined since then. There seem to be two reasons for this. One is Martine Nida-Rümeline criticism against the ability hypothesis, where he tries to show that what Mary learns upon release is more than a bunch of abilities. The other is Jason Stanley and Timothy Williamson's criticism. They argue that the abilities Mary acquires amount to "knowledge-how", which in turn is reduced to "knowledge-that." This essay aims to defend the ability hypothesis against these criticisms, and thereby restore the status of the ability hypothesis. As for the first criticism, it is argued that the kind of knowledge Mary acquires other than the abilities is "demonstrative knowledge," which not only poses no threat to physicalism, but also is orthogonal to phenomenal knowledge. As for the second criticism, it is argued that by ruling out "the ability to imagine experiences," the ability hypothesis can survive Stanley and Williamson's criticism.

  • The purpose of this study is to find out whether there is a difference in achievement between blocked practice and interleaved practice according to the difference in domain and type of learning content in mathematics subject, and through this result, it is to confirm whether the effect of interleaved practice in mathematics learning is due to the 'Discriminative-contrast Hypothesis' or the 'Distributed-practice Hypothesis'. Although interleaved practice is more effective than blocked practice, previous studies have not shown consistent results regarding the cause. Therefore, in this study, 103 first-year middle school students were randomly assigned to blocked practice, interleaved practice, remote blocked practice, and remote interleaved practice groups had learning activities over 4 times. The results reveals that the effect of interleaved practice appeared in similar types in the same domain, but the effect of interleaved practice did not appear in different types in different domain. In addition, through this result, it was confirmed that the effect of interleaved practice was due to the 'Discriminative-contrast hypothesis' rather than the 'Distributed-practice hypothesis'. Further research topics were suggested after the issues on the research method and the findings were discussed.

  • The purpose of the present study was to test the hypothesis that student's abductive reasoning skills play an important role in the generation of hypotheses on pendulum motion tasks. To test the hypothesis, a hypothesis-generating test on the pendulum motion and a prior knowledge test about the length of the pendulum motion were developed and administered to a sample of 5th grade children. A significant number of subjects who have the prior knowledge about the length of the pendulum motion failed to apply that prior knowledge to generate a hypothesis on a swing task. These results showed that students' failure in hypothesis-generating was related to their deficiency in abductive reasoning ability, rather than the simple lack of prior knowledge. Furthermore, children's successful generating hypothesis should be required their abductive reasoning skills as well as prior knowledge. Therefore, this study supports the notion that abductive reasoning ability beyond prior knowledge plays an important role in the process of hypothesis-generation. This study suggests that science education should provide teaching about abdctive reasoning as well as scientific declarative knowledge for developing children's hypothesis-generating skills.

  • Previous studies on the effect of incidental semantic priming on judgment, have focused mainly on mutually exclusive hypotheses. However, the present study explored whether incidental semantic activation affects diagnostic inference depending on the type of the hypothesis: mutually exclusive hypotheses vs compatible hypotheses. In Experiment 1, in case of mutually exclusive hypotheses, the final hypothesis was selected according to the incidental semantic priming, but there was no difference in the number of generated hypothesis in comparison with the control. However, for compatible hypotheses (i.e., both hypotheses can be true), the semantic priming affected the number of generated hypotheses, but not the selection of the final hypothesis. The same pattern of results was observed even when the cognitive load was increased. In Experiment 2, we found a boundary condition of incidental semantic activation on diagnostic inference. When cues related to each of the hypotheses were presented simultaneously, the incidental semantic effect disappeared. These results suggest that people consider all possible cues when making diagnostic inference in daily life. In light of these findings, further research on hypothesis generation/evaluation should take the type of hypothesis into account.
