  • Quantification of error possibility, in an HRA process, should be performed so that the result of the qualitative analysis can be utilized in other areas in conjunction with overall safety estimation results. And also, the quantification is an essential process to analyze the error possibility in detail and to obtain countermeasures for the errors through screening procedures. In previous studies for the quantification of error possibility, nominal values were assigned by the experts' judgements and utilized as corresponding probabilities. The values assigned by experts' experiences and judgements, however, require verifications on their reliability. In this study, the validity of new error possibility values in new MCR design was verified by using the Onisawa's model which utilizes fuzzy linguistic values to estimate human error probabilities. With the model of error probabilities are represented as analyst's estimations and natural language expression instead of numerical values. As results, the experts' estimation values about error probabilities are well agreed to the existing error probability estimation model. Thus, it was concluded that the occurrence probabilities of errors derived from the human error analysis process can be assessed by nominal values suggested in the previous studies. It is also expected that our analysis method can supplement the conventional HRA method because the nominal values are based on the consideration of various influencing factors such as PSFs.

  • This paper reviews the toxicological role of median lethal dose ($LD_50$) based on animal and human data. Animal oral $LD_50$ values of eighty seven chemicals were collected and comparatively evaluated with human minimum toxic dose ($TD_50$). In general, animal $LD_50$ values were much higher than human $TD_50$. The ratios between $LD_50$ and TDlo were ranged from 0.01 and over 1000, suggesting safety factor of up to 1000 between humans and animals in the case of acute toxicity data. However, about 40% of chemicals investigated were within the ratio of 10. Although the cases (N=20) were small, $LD_50$ values of guinea pig were closer to human TDlo than those of other animal species. In interanimal species (rat, mouse, rabbit, dog), the ratios of $LD_50$ values were between 0.1 and 5 (up to 50-fold difference). When the data are analyzed by chemical strut-ares, human $TD_50$ values were very close to rat oral $LD_50$ values. These data suggest that rat oral $LD_50$ value might be a useful parameter predicting human TDlo and one animal species could be sufficient for acute toxicity test.

  • This study is a theoretical account of HRs requirements in educational institutions in light of the growing influence of digital technology on human rights. It intends to reveal prominent human and civilizational values encapsulated in modern human rights regulations. It dwells on educational and societal requirements for educational inclusion in the school and university curricula in light of changes that have taken place in HRs in the digital age. Relying on the descriptive documentary research design, the study concluded that HRs are inherently moral duties and fixed values. They include the importance of tolerance, freedom, peace, justice, science, work, and equality. Because education is arguably based on human and civilized values, educational foundations require intake of awareness, systematic integration and responsibility from all academic and community institutions, including family and media institutions. The article closes on a note of how technology has impacted human rights in the digital age. It provides implications and recommendations to pedagogies accordingly.

  • This study is about the modeling of comfort feeling structure in indoor environments. To represent the degree of practical comfort feeling level in an environment, we measured elements of human sense and resultant elements of comfort feeling such as coziness, refreshment, and freshness with physical values(temperature, illumination, noise. etc.). The relationships of elements of human sense and elements of comfort feeling were formulated as a fuzzy model. And a hybrid-neural network with three layers were designed where obtained from fuzzy membership function values of the elements of human sense were used as inputs, and given as fuzzy membership function values of resultant elements of comfort feeling were used as outputs. Both kinds of fuzzy membership function values were obtained from physical values. The network was trained by measured data set. The proposed hybrid-neural network were tested and proposed a more realistic model of comfort feeling structure in indoor environments.

The data were collected through self-reported questionnaires in April, 1999. Categories for classifying used in the content analysis of the responses were : (1) human life (2) patient relationship (3) task relationship and (4) co-worker relationship. The results of the study are as follows ; 1) The ethical values of students in nursing and medicine were in the direction of utilitarian in the area of human life. The ethical values of students in nursing and medicine were in the direction of a deontological position in the area of patient relationship. The mean score for students in nursing was significantly higher than for those in medicine(P<0.01) The ethical values of students in nursing and medicine was in the direction of utilitarian in the area of task relationship. The mean score for students in medicine was significantly lower than that of students in nursing(P<0.01). The ethical values of students in nursing and medicine was definitely in the direction of a deontological position in co-worker. The mean score for students in nursing was significantly higher than that of students medicine (P<0.05). 2) A positive correlation was found between the area of human life and patient relationship(P<0.05), patient and task relationship(P<0.01), and task and co-worker relationship(P<0.05) for students in nursing. On the other hand, the area of human life was positively correlated with patient, task and co-worker relationship area(P<0.05) for students in medicine. The area of patient relationship was also positively correlated with co -worker relationship for the students in medicine(P<0.01). 3) The ethical values of students in nursing were related to demographic characteristics ; degree of participation in religion(P<0.01)and degree of recognition of an ethical codes(P<0.05), on the other hand, the ethical values of students in medicine showed no significant differences according to demogrephic variables.

  • The purpose of this study is to elucidate mutual link of a person's human nature and his or her sense of values. In general, a person's human nature and his or her personality is used differently in its concept. However, in this study, it is revealed that these two things are closely connected. A person's human nature without personality is meaningless and personality without human nature cannot be existed. A person's human nature is the ground for existence of personality and personality is individual thing that is made on the universal ground of human nature. Personality is colligation of value that a person pursues. Every person pursues value. Therefore every person cannot help being personality. However personality is not a joint thing but an individual thing. Spiritual-philosophically, personality is exactly individual spirit. Therefore personality cannot be classified as personality or impersonality. It can be classified as high-leveled personality or low-leveled personality. And the foundation for existence of morality lies not on a person's human nature but on a person's personality. A person can be moral or immoral according to the value he pursues. Because personality is made on the basis of a person's human nature and the colligation of value that an individual person pursues is personality, a person's human nature is a vessel that contains his or her sense of values. A person's human nature and his or her sense of values are changed affecting each other. These two things are the sons of the age that is affected by the age. That's because human who is a container of human nature and his or her sense of values is both a natural being and a moral being.

  • This study aims to show how tradition and modernity has interacted to produce the aesthetic consciousness of body and dress in contemporary Korea. For this purpose, documentary studies were proceeded. And photos of the modern Korean dress from 1980 to 1997 were analyzed. The results are as follows: First, the body form was studied in terms of exposure and concealment of the physical body parts and the perception of body was classified into two categories, the abstract and the realistic. And the dress form was studied in silhouette and the perception of dress was assorted as body priority and clothes priority. Second, the aesthetic values of body were categorized to divinity, humanity and sexuality. And the aesthetic values of dress were defined in relation to the aesthetic values of body as ascetic beauty, pure beauty, natural beauty and erotic beauty. Third, while the traditional Korean costume (Hanbok) pursues the aesthetic values of divinity and humanity of human body and ascetic beauty, pure beauty and natural beauty on the aesthetic values of humanity of human body and the pure beauty and natural beauty of dress. The contemporary Korean fashion expresses the aesthetic values of divinity, humanity and sexuality of human body and the aesthetic values of ascetic beauty, pure beauty, natural beauty and erotic beauty of dress. In conclusion, the emphasis of sexuality of body and erotic beauty of dress in the modern Korean dress can be interpreted as the change of the aesthetic consciousness of body and dress in contemporary Korean by the influence of the western modernity.

  • Water quality criteria for human health protection are derived based on the human health risk assessment. Water quality criteria in Korean freshwater bodies have been derived according to the equations developed by the US Environmental Protection Agency. The equations include the fish intake parameter, which is very important factor that significantly influences on the criteria derivation. So far, several fish intake values were used in human health risk assessment for water quality standards and effluent standards. However, these values are not consistent and they refer to various sources. Therefore, there is a need to suggest the most appropriate value of fish intake parameter to derive freshwater quality criteria in Korea. In this study, national and international fish intake values were widely collected and evaluated to select the adequate value of fish intake parameter that can be applied in Korea. The USEPA presented fish intake parameter as the 17.5 g/day for general adults and sport fishers and 142.4 g/day for subsistence fishers. In Korean reports, wide range values of 2 to 67.7 g/day were suggested as fish intake value. These values included finfish and shellfish intakes in common but had various habits. This study found that the 52.4 g/day suggested in Korean Exposure Factors Handbook published by the Ministry of Environment in 2007 seemed to be the suitable fish intake parameter to derive the freshwater quality criteria in Korea. The value is based on water corrected intakes of finfish and shellfish present in freshwater and coastal areas. We expect that this report can be useful to select suitable fish intake value in human health risk assessment for establishing freshwater quality standard in Korea.

  • In order to investigate psychoacoustic characteristics of fibers, and to compare them with sound physical parameters, each sound of 25 different fabrics consisted of a single fiber such as wool, cotton, silk, polyester, and nylon was recorded. Sounds of specimens were transformed into critical band diagram and psychoacoustic characteristics including loudness and sharpness for each sound were calculated based on Zwicker's models. Physical parameters such as the level pressure of total sound (LPT), level ranges (ΔL), frequency differences (Δf), AR coefficients (ARC, ARF, ARE) were obtained in fast fourier transform (FFT) spectrum. Nylon taffeta showed higher values for loudness than 2.5 sone corresponding to human low conversation, while most silk fibers generated less louder showing lower values for loudness than 1.0 sone. Wool fibers had higher loudness mean value than that of cotton, while the two fibers didn't differ in LPT. Loudness showed high positive correlation coefficients with both LPT and ARC. Sharpness values were higher for wool fiber group than other fibers. Sharpness was not concerned with loudness, LPT, and ARC, but the fabrics with higher values for sharpness tended to show higher ΔL.
