The purpose of the present study was to test the validity of the confirming abduction model (CAM). CAM is a process model which explains how reasoners confirm their hypothetical explicans. To test this model, 154 8th grade students were sampled from one middle school in Korea. Three types of vapor condensation hypothesis confirming tests were developed and administered to the subjects. The results of this study revealed that student confidence increased when hypothetical explicans were borrowed into experienced phenomena from questioning phenomena. These results validated CAM. According to CAM, the process. of confirming hypothetical explican is as follows: representing a questioning phenomenon, representing an experienced phenomenon that is similar to the questioning phenomenon, representing the hypothetical explican of the questioning phenomenon, comparing the questioning phenomenon with the experienced phenomenon, and borrowing the hypothetical explican as the hypothetical explican of the experienced phenomenon from the hypothetical explican of the questioning phenomenon. This study also discussed the implications of these findings for teaching and learning in science education.

The purpose of this study is to reveal that the deconstructive dis de phenomenon in contemporary fashion beauty design can be interpreted from the viewpoint of Korean aesthetics by having an open mind of coexistence. The typical characteristics of dis de phenomenon are decomposition, decentralization, and discontinuity, and these can be compared with beauty of non-artificialness, unity, and humor, which are characteristics of Korean aesthetics. In other words, the dis de-phenomenon rejects traditional composition and uniformized expression, and seeks various images by accepting the bi-national confrontation concept, this is similar to Korean aesthetics, which experienced atypical diversity by concentrating on the inner spirit rather than the outer form through indifference to technique, form, and honest human emotion.

There are many cases that interrupt the production process because of malfunctions caused by electronic circuit boards which control equipment, but it is difficult to distinctly identify the causes in many cases. Especially, CMOS devices with the control logic circuit return automatically to normal state after their own faults. Therefore it is not easy to analyze the problems with electronic circuit boards. Recently, nuclear power plant experienced a failure due to the malfunction of electronic circuit boards and it was identified that the reason of the malfunction was because of latch-up phenomenon caused by external surge in electronic devices. This paper presents the causes and the phenomenon of latch-up by experiment and also a way using counter EMF diodes, noise filters and surge protective devices to prevent latch-up phenomenon from electronic circuit boards, finally confirms the effectiveness of the result by experiment.

This study examined, through a qualitative approach, the viewpoints and beliefs toward divorce held by people who have experienced a divorce. In-depth interviews with divorced individuals (two males and twelve females) were conducted for this study. The findings of the study are summarized as follows. First, the participants of the study had a tendency to withdraw. In other words, they felt powerless and lonely, and they think of themselves as a failure. Second, they clearly recognized the double standard in society toward divorce. They strongly felt that people who had shown tolerant attitudes toward divorce when it was a distant phenomenon suddenly took a different attitude when a divorce occurred to a relative. The fact that openly stated viewpoints toward divorce can be significantly different than unstated attitudes made the participants' lives still harder by adding another burden to the difficulties they already faced from the divorce. As a result, they would rather hide the fact that they were divorced than be open about it with other people. Aside from highly significant others, they attempted to conceal their divorce from others whenever possible. Third, as people who have already experienced divorce, they seem to take a more careful attitude toward divorce than those who have not experienced a divorce. The participants pointed to the social responsibilities to promote public understanding and a sense of value about divorce, and they hoped that our society would communicate better about the difficulties of getting divorced from the perspective of those who have experienced divorce. The participants believed this would ultimately contribute to preventing divorce among others. This study is expected to expand understanding toward the phenomenon of divorce in Korean society, and further, to provide basic information for a clearer understanding of the current state of the Korean family.

Large-amplitude, combustion-induced oscillations are observed in most systems involving continuous flow, such as aeroengine afterburners, gas boilers and rocket motors. Strong furnace vibration is typically characterized by the presence of well developed standing waves in the furnace, generating high pressure pulsation and causing structural vibration of the furnace walls. 320MW NG boilers have been experienced high vibration frequently since reconstruction works. Excessive furnace vibration was encountered when a burner air rate is suddenly reduced during load zone changed from 270MW to 300MW. An investigation showed that the primary cause of the vibration was induced by combustion low air flow rate. This paper describes phenomenon examination on strong furnace vibration due to the change of boiler operating conditions.

This study uses qualitative data to examine the dynamics and barriers of the delayed family formation phenomenon among the never-married professionals in Korea. The data was drawn from focus groups of 14 never-married professionals aged 28 through 40. The investigation depicts several dimensions of the circumstances of never-married professionals that have not garnered much attention in the literature. This research provides initial evidence of critical influences within the socio-cultural contexts of the participants' dating behaviors as well as the willingness to many. Two different realities, based on gender, were discovered: both male and female voluntarily delayed marriage to pursue their career, education and success. As both reached their career goals, however, male participants experienced a rise in their value as a marriage prospect whereas females experienced decreased value as a marriage prospect. Hence, neo-traditional familism was the dominant value among the participants, but it also functioned as a major barrier to family formation because in the present value system, female professionals, must still struggle with the dual burdens of work and family management.

The purpose of an internal control system is to prevent the occurrence of errors and fraud in the process of producing accounting information, thereby providing investors with reliable information. For the effective operation of an internal control system, it is necessary to secure a sufficient number of personnel and experienced staff. This study focuses on the personnel directly involved in producing accounting information, examining whether companies that invest in their internal control staff experience a mitigation in the phenomenon of valuation errors. The analysis revealed that the size and experience months of the personnel responsible for internal control have a significant negative relationship with valuation errors. This result implies that by securing sufficient personnel for the smooth operation of the internal control system and placing experienced staff within the system, investors can effectively make judgments about the intrinsic value based on quality accounting information, thereby reducing valuation errors.
