The purpose of this study was to provide basic data necessary for educating dental hygiene students by establishing a desirable sense of ethics values. In this descriptive research, 97 dental hygiene students and 100 non-dental hygiene students (in other health related fields) from Daegu Gyeongbuk City were selected. Tools used for data analysis were descriptive statistics, t-test, one-way ANOVA, Scheffe test and correlation analysis with SPSS/WIN 17.0 version. Average scores for consciousness of biomedical ethics in dental hygiene students was 2.87, and in non-dental hygiene students, 2.82. When differences in the consciousness of biomedical ethics of dental hygiene and non-dental hygiene students were compared, dental hygiene students had significantly higher scores for prenatal diagnosis of fetus, right to life of newborn, right to life of fetus, brain death, artificial abortion, but significantly lower for organ transplantation. Variables which influenced consciousness of biomedical ethics were etihcal values in the dental hygiene students and intent to attend a class in biomedical ethics, quantity and quality of experience of hearing for biomedical ethics and religion in the non-dental hygiene students. Continuing educational programs need to be considered and attention given to the significant variables that can promote consciousness of biomedical ethics in dental hygiene students.

This study attempts to identify the changes in social reactions to disabilities in general, and to research the contextual implication of these changes in social work practice in Korea. In the early years after the Industrial Revolution, disability was conceived as social unfitness and it was assumed that the cause and responsibility could be attributed to people with disabilities. But, in the midst and late 20th century, social responsibility for people with disabilities was argued and generally accepted. As the results of these changes, conceptual models explaining disabilities have changed gradually; there has been a transition, so called, from individual model to social model. In a similar vein, WHO has refined the definition and classification of disability. Related to these changes, social welfare service paradigm for people with disabilities has shifted. This paradigm shift can be explained with the perspective of strength approach, empowerment approach, case management and independent living model. In Korea, 1998 Act on welfare for people with disabilities meant that social service for the disabled were categorized with, namely, residential service, community rehabilitation service and vocational rehabilitation service. Recently, the extent of these services has been rapidly broadened. In these situation, this study researched to identify the implications on social work practice in the context of changes in social response, conceptual model, definition and also service paradigm. Such as the followings are enumerated for the implications: disabled person's participation in assessment process, development of assessment tools focusing on social and environmental perspectives, reinforcement of information service helping self-determination, supporting on formal and informal helping network, expanding self-help programs and, finally, a shift from displacement model to support model.

In male reproducible health, fertility and IVF (in-vitro fertilization), semen analysis has been most important. Semen analysis can be divided into concentration, motional and morphological analysis of sperm. The existing method which was developed earlier to analyze semen concentrated on the sperm motility analysis. To provide more useful and precise solutions for clinical problems such as infertility, semen analysis must include sperm morphological analysis. But the traditional tools for semen analysis are subjective, imprecise, inaccurate, difficult to standardize, and difficult to reproduce. Therefore, with the help of development of microcomputers and image processing techniques, we developed a new sperm morphology analyzer to overcome these problems. In this study the agreement on percent normal morphology was studied between different observers and a computerized sperm morphology analyzer on a slide-by-slide basis using strict criteria. Slides from 30 different patients from the SNUH andrology laboratory were selected randomly. Microscopic fields and sperm cells were chosen randomly and percent normal morphology was recorded. The ability of sperm morphology analyzer to repeat the same reading for normal and abnormal cells was studied. The results showed that there was no significant bias between two experienced observers. The limits of agreement were 4.1%${\sim}$-3.8%. The Pearson correlation coefficient between readers was 0.79. Between the manual and sperm morphology analyzer, the same findings were reported. In this experiments the slides were stained by two different methods, PAP and Diff-Quik staining methods. The limits of agreement were 7.2%${\sim}$-5.7% and 6.0%${\sim}$-6.3%, respectively. The Pearson correlation coefficients ware 0.76 and 0.91, respectively. The limits of agreement was tighter below 20% normal forms. In the experiments of repeatability, 52 cells stained by PAP and Diff-Quik staining methods were analyzed three times in succession. Estimating pairwise agreement, the kappa statistic for the pairs were 0.76, 0.81, 0.86, and 0.75, 0.88, 0.88 respectively. In this study it was shown that there was good agreement between manual and computerized assessment of normal and abnormal cells. The repeatability and agreement per slide of computerized sperm morphology analyzer was excellent. The computer's ability to classify normal morphology per slide is promising. Based on results obtained, this system can be of clinical value both in andrology laboratories and IVF units.

Environmental DNA (eDNA) is a genetic material derived from organisms in various environments (water, soil, and air). eDNA has many advantages, such as high sensitivity, short investigation time, investigation safety, and accurate species identification. For this reason, it is used in various fields, such as biological monitoring and searching for harmful and endangered organisms. To collect eDNA from a freshwater ecosystem, it is necessary to consider the target organism and gene and a wide variety of items, such as on-site filtration and eDNA preservation methods. In particular, the method of collecting eDNA from the environment is directly related to the eDNA concentration, and when collecting eDNA using an appropriate collection method, accurate (good quality) analysis results can be obtained. In addition, in preserving and extracting eDNA collected from the freshwater ecosystem, when an accurate method is used, the concentration of eDNA distributed in the field can be accurately analyzed. Therefore, for researchers at the initial stage of eDNA research, the eDNA technology poses a difficult barrier to overcome. Thus, basic knowledge of eDNA surveys is necessary. In this study, we introduced sampling of eDNA and transport of sampled eDNA in aquatic ecosystems and extraction methods for eDNA in the laboratory. In addition, we introduced simpler and more efficient eDNA collection tools. On this basis, we hope that the eDNA technique could be more widely used to study aquatic ecosystems and help researchers who are starting to use the eDNA technique.

Objective: To develop and verify the usability of a cognitive rehabilitation system with diverse cognitive functional levels based on tangible objects for the elderly population. Methods: A study was conducted to investigate the system's strengths and weaknesses by upgrading it with responses from two groups of 15 patients and 4 occupational therapists. After undergoing three forms of training - regarding executive function, memory, and concentration for a total of 20-30 min, the participants were asked to answer a structured questionnaire about contents of the three forms of training, hardware including the tablet PC functioning as a CPU and display media and tangible objects, and satisfaction of experiential usage of the system. Results: Both groups responded that the most interesting training area was executive function while the least interesting was concentration. Six participants reported that the size of the screen of the tablet PC was inappropriate, and five responded that the size of the tool was inappropriate. All therapists and 40% of the patients responded that they were satisfied with this system. Conclusion: This system's features include easy manipulation of tangible tools for performing training tasks, easy selection of and training in cognitive areas based on users' needs, and automatic adjustment of difficulty level based on users' performance. The training environment was designed to be similar to the natural environment by using tangible objects in both hands as input devices for the system, and the system was considered as an alternative to the lack of community cognitive rehabilitation specialists.
