  • The objective of this study was to compare the wood anatomical characteristics of local tree species in Moluccas, Indonesia i.e., Moluccan ironwood (Intsia bijuga), linggua (Pterocarpus indicus), red meranti (Shorea parvifolia), and gofasa (Vitex cofassus). Qualitative evaluation was conducted by observing the anatomical structure in cross, radial, and tangential sections of each sample. For the quantitative evaluation, the dimensions of vessels, rays, and fibers were measured. Qualitative evaluation showed that crystals were observed in Moluccan ironwood, linggua, and gofasa, while resin canals were only observed in red meranti. Tyloses were frequently observed in gofasa but infrequently observed in linggua and red meranti. Quantitative evaluation showed that Moluccan ironwood with the higher density had thicker fiber wall, higher quantity of ray number, and wider rays than the other species. Red meranti had higher values of ray height and fiber length than the other three species. The results also revealed that linggua showed the highest values of relative crystallinity and crystallite width. Red meranti and gofasa showed similar values of relative crystallinity and crystallite width, while Moluccan ironwood showed the lowest values. The basic qualitative and quantitative anatomical characteristics discussed could provide useful information for further utilizations of such wood species.

  • Purpose: This study was to determine the current trend of nursing research as exploring both quantitative and qualitative methodologies, and to provide the explicit direction to improve the quality of published papers. Methods: Total of 366 articles published between 2004 and 2006 was reviewed using the criteria of analysis. Results: There was more number of quantitative studies than qualitative studies. More studies were conducted with subjects who had health problems, and studies that targeted women and elderly population have been significantly increased. In quantitative methodology, utilization of experimental and quasi-experimental designs has been increased, however descriptive study was dominant as yet. In qualitative methodology, studies using grounded theory and phenomenology were frequently published. It was noted that theoretical framework and rational for sample size were rarely presented in quantitative study. Philosophical position and the process of preparation for study, which guided the research, were not clearly described in qualitative study. Conclusion: The findings of this review suggest that published studies have been improved and diversified, however, detailed and clear evaluation tool that assesses study process and method should be developed as a way to further improve the quality of published papers.

  • The purposes of this study were to describe systemically 18 years of oncology nursing research in Korea and suggest it's direction in future. 149 nursing studies published from 1980 to 1998 were selected for the present study. There were examined the source and the design of study, type of subjects, measurement variables, the intervention outcome of experimental research, and theme of qualitative research. The results were as follows : 1. 121 of 149 studies were composed of master thesis and dissertation of graduate school. There were 55 correlations, 30 descriptions, 19 comparisons, 19 qualitative studies and 2 Q-methods as the type of research design. 2. Cancer patients without describing specified diagnosis as subjects' characteristic were 44 of total studies. The others had various diagnoses such as gastric cancer, uterine cancer, breast cancer, leukemia, lymphoma, colorectal cancer, and lung cancer. According to treatment type, patients receiving chemotherapy were the highest number distribution as 53 of all researches. 3. Most measurement instruments used for research were translated it into Korean that developed by foreigners, such as Zung's depression, Spielberg's anxiety, and Wallston's locus of control. 4. Quality of life was shown the most frequently among correlational researches. the next one was depression, the third was hope, and so on. 5. There was the most frequent comparison between cancer and non-cancer patients in comparative researches. It was surveyed those variables as diet habits, risk factors, stressful life events, anxiety and depression, and self-care capacity between two groups. 6. The subjects were mostly chemotherapy patients as 15 of 24 experimental studies. Oral care and education were respectively the highest experimental interventions. 7. Qualitative researches about cancer were reported since 1991. Their themes were illness experience, adaptation process, dying experience, family experience, hope, caring, experience of health behavior, meaning of chemotherapy and experience of cancer survivor. Phenomenologic methodology was designed above 50% of qualitative researches. According to the above findings, cancer research had increased since 1990 and done mostly by descriptive design but a few experimental studies. As recommendations for the future, It is necessary to study the comparison of oncology nursing research internationally, the replication to establish the effect of nursing intervention, and the family care of cancer patient.

  • The prevention of safety accidents can be achieved through Harvey's 3E's: Engineering, Enforcement, and Education. On construction sites, however, enforcement and engineering did not prove to be valid ways of reducing the number of safety accidents, as enforcement and engineering have failed to overcome and/or supplement the realistic limits regarding the relatively lower education levels of construction workers and the communication issues with foreign workers. On the other hand, safety education can enable the advancement of safety management by enhancing the educational contents and their methods of delivery. To improve the efficiency of safety education via educational contents, this research conducted a qualitative and quantitative analysis on the validity of the newly educational contents by overviewing possible accident types in different work phases. Of the accident types identified by the qualitative analysis, neither highly important nor insignificant accident types were found, yet all the suggested types are found to be required. In addition, this study did not find any significant differences in the occurrence probability of safety accidents related to the level of importance of each type of accident. The qualitative analysis in this research verified that the suggested accident types can be valid, educational material that can take into account future safety accidents.

  • 다층신경망 (multilayer perceptron)이 다른 패턴인식 방법에 비해 여러 가지 이점을 제공하지만 다층신경망에 기반한 화자증명 시스템은 낮은 증명오류를 달성하기 위한 대규모 배경화자로 인한 느린 등록속도의 문제를 안는다. 이 문제를 해결하기 위해 QnDCS(quantitative discriminative cohort speakers) 방법에서 화자군집 방법을 다층신경망 기반화자증명 시스템에 도입하여 화자등록에 필요한 배경화자의 수를 줄이려는 시도가 있었다. QnDCS 방법이 목적을 어느 정도 달성하긴 했지만 등록속도의 향상률이 만족할만한 수준이지 못했다. 본 논문에서는 보다 높은 등록속도 향상률을 달성하기 위한 방법으로서, 선택되는 배경화자의 수를 더욱 낮추는 정질에 기반한 기준을 도입한 QlDCS (qualitative discriminative cohort speakers) 방법을 제안한다. 두 방법에 대한 성능평가를 위해 다층신경망과 지속음에 기반한 화자증명 시스템과 음성 데이터베이스를 사용한 실험을 실시한다 그 결과 제안한 방법이 QlDCS에 비해 온라인 방식의 EBP (error backpropagation)에 대한 학습속도 향상률 면에서 2배 이상 더 짧은 시간 내에 화자를 등록하는 것으로 나타나 보다 높은 효율을 지녔음을 증명한다.

  • Fuzzy simulation predicts the behaviors of real system based on a model by qualitative reasoning methods and simulates the representation of ambiguous values on the real system variables using the theory of fuzzy sets. During the simulation, however, unnecessary behaviors due to the fuzzy representation are created, and the number of states of system variables changing temporally in the time axis is drastically increased. In this paper, we present a new algorithm which eliminates the spurious behaviors from the great number of result values due to the results of the fuzzy operation, and reduces the number of the states by transforming the complex state transition rules. This paper also shows the easy implementation of the simulation by using the existing package while it is difficult on the PC due to the complexities of the calculation.

  • This study aims to apply corpus-based approach to analyze The Yellow Wall-Paper and Herland written by Charlotte Perkins Gilman, a women's rights activist in the late nineteenth-century America. Although both works have attracted feminists' attention to the woman question that concerned Gilman, discussion on her language features and their relation to the literary themes of these two works is still in need. In this corpus-based analysis, we argue that the main themes of different literary works can be revealed through linguistic patterns identified by number and gender features of nouns and pronouns in the contrast of two works and a balanced corpus. The linguistic features (number and gender) have been related with two themes, the 'group and individual' and the 'feminine and masculine', and are further interpreted in terms of mothering and feminine consciousness. By adopting linguistic approach, our study provides quantitative and qualitative evidence to verify the established themes and arguments of these literary texts.

  • 본 연구는 고령군이 놓여 있는 교육환경과 지역의 역량 강화를 위해 지방자체단체가 실시하고 있는 교육의 질적 개선책의 의의와 한계에 대해 검토하였다. 고령군은 여느 농촌과 마찬가지로 학생수의 자연적 감소로 인하여 소규모 학교가 계속해서 통폐합되어 왔으며, 지역의 우수한 학생들이 인근 도시로 계속해서 빠져 나가는 사회적 감소가 가중되어 교육환경은 더욱 열악해져 지역 발전의 큰 걸림돌이 되어 왔다. 이에 고령군은 무엇보다도 교육의 질적 개선이 지역 발전의 동력이라고 판단하여 지방자치단체와 지역주민이 연대하여 고령군교육발전위원회를 설립하여 기금을 조성하고, 이를 다양한 교육 개선 및 장학 사업을 위해 적극 투자해 오고 있다. 특히, 명문학교 육성, 공립학원으로서의 대가야교육원 운영, 군립독서실 설치 등 지방자치단체의 핵심적 정책들이 차츰 성과를 거두고 있으며 이는 지역의 경쟁력의 원천이 되고 있다. 그러나 이러한 일련의 정책의 추진 과정 속에서 지방자치단체와 교육청 및 단위 학교간의 마찰, 질 높은 교육적 혜택에 대한 접근성의 차이 등 새로운 긴장과 갈등이 나타나고 있다. 따라서 지역사회 내에서의 교육의 형평성을 담보할 수 있는 질적 개선이 새로운 과제로 요구되고 있다.
