This paper aims to give an overview of the methods to inherently prevent human errors and to effectively mitigate the consequences of such errors by securing defense-in-depth during plant management through the advanced man-machine interface system (MMIS). It is needless to stress the significance of human error reduction during an accident in nuclear power plants (NPPs). Unexpected shutdowns caused by human errors not only threaten nuclear safety but also make public acceptance of nuclear power extremely lower. We have to recognize there must be the possibility of human errors occurring since humans are not essentially perfect particularly under stressful conditions. However, we have the opportunity to improve such a situation through advanced information and communication technologies on the basis of lessons learned from our experiences. As important lessons, authors explained key issues associated with automation, man-machine interface, operator support systems, and procedures. Upon this investigation, we outlined the concept and technical factors to develop advanced automation, operation and maintenance support systems, and computer-based procedures using wired/wireless technology. It should be noted that the ultimate responsibility of nuclear safety obviously belongs to humans not to machines. Therefore, safety culture including education and training, which is a kind of organizational factor, should be emphasized as well. In regard to safety culture for human error reduction, several issues that we are facing these days were described. We expect the ideas of the advanced MMIS proposed in this paper to lead in the future direction of related researches and finally supplement the safety of NPPs.

Oysters are known to be carriers of food-born diseases, but research on viruses in Korean oysters is scarce despite its importance for public health. We therefore tested oysters cultivated in Goheung, Seosan, Chungmu, and Tongyeong, for viral contamination using cell culture and integrated cell culture PCR (ICC-PCR) with Buffalo green monkey kidney (BGMK) and human lung epithelial (A549) cells. Additional screens via PCR, amplifying viral nucleic acids extracted from oysters supplemented our analysis. Our methods found 23.6 %, 50.9 %, and 89.1 % of all oysters to be positive for adenoviruses when cell culture, ICC-PCR, and direct PCR, respectively, was used to conduct the screen. The same methodology identified enteroviruses in 5.45%, 30.9%, and 10.9% of all cases. Most of the detected enteroviruses (81.3%) were similar to poliovirus type 1; the remainder resembled coxsackievirus type A1. A homology search with the adenoviral sequences revealed similarities to adenovirus subgenera C (type 2, 5, and 6), D (type 44), and F (enteric type 40 and 41). Adenovirus-positive samples were more abundant in A549 cells (47.3%) than in BGMK cells (18.2 %), while the reverse was true for enteroviruses (21.8 % vs. 14.5 %). Our data demonstrate that Korean oysters are heavily contaminated with enteric viruses, which is readily detectable via ICC-PCR using a combination of A549 and BGMK cells.

The purpose of this study is to provide fundamental information for the development of new sex education image media through the analysis of those tools produced by Planned Parenthood Federation of Korea. Twenty three video tapes related to the sex education were analysed. The data were sampled on the basis of the sex education instructions for primary and secondary schools published by the Seoul Office of Education in 1996 and the list of sex education information composed by the Planned Parenthood Federation of Korea with the following requirements. 1) The education materials are oriented to the middle and high school students as well a juveniles and are being used in public health centers and schools. 2) The education materials are not confined to the single subject such as AIDS or contraception. Because this study is focused on the analysis of image media, an analysis method widely and effectively used in public media study was chosen. The frequency analysis and percentage treatment were done by an SAS program. The results of the study are as follows : 1. An analysis of the material structure type showed that the frequency of the following subjects in 15 video tapes, composed as drama and cartoon, had this decreasing orde : sex behavior, sex relation ships, sex health, human development, personal technique, and society and culture. 2. The eight tapes of explanation and counseling showed a different sequence from that of the drama and cartoon material, primarily treating human development with 5419 seconds (47.9%) of type. The following were also considered in decreasing order: at 2000seconds (17.6%) sex behavior, at 1366 seconds (12.1%) sex health, at 1240 seconds (11.0%) society and culture, at 667 seconds (6.0%) relation ships, and at 611 seconds (5.4%) personal technique. 3. In a thematic analysis those education materials dealing with human development show this frequency sequence: anatomic physiology, reproduction, and adolescence. In relation, ships the sequence is dates, love, marriage and vows, and family. For personal technique, it is expressed as asking for help, and an empnasis on moral values. For sex behavior, they focus on abstinence, the co-responsibility of sex behavior, the sexual response of the human, and sexual nightmares. For the sex health area, the focus is contraception with abortion and reproductive health following that. In society and culture diversity is considered. 4. An analysis of the differences in production and content between 1980s and 1990s was also done. For materials produced in the 1980s the frequency of the subjects follows this order: sex behavior, human development, relation ships, sex health, personal technique, and society and culture with sub subjects such as abstinence, dating, adolescence, anatomic physiology, reproduction, calls for help, and the sexual response of a human being. For materials produced in the 1990s, highest frequency was sex behavior, the same as the 1980s. The rest of the material follows this decreasing order: relationships, human development, sex health, society and culture, and personal technique with sub subjects such as dating, co-resposibility in sex behavior, abstinence, and love frequently considered.

It has been established that a graft of fibroblasts is able to improve wound healing. However, there has been no research on the effect of a graft of bone marrow stromal cells on wound healing. The wound healing process requires cell proliferation and production of extracellular matrix and various growth factors. The purpose of this study was to compare the abilities of human fibroblasts and bone marrow stromal cells, which contains mesenchymal stem cells, to proliferate and to produce collagen. Human bone marrow stromal cells and fibroblasts were isolated from bone marrow and dermis of the same patients and grown in culture respectively. Cell proliferation and production of type I collagen by human bone marrow stromal cells and dermal fibroblasts were examined by MTT method and by ELISA of cell culture media on day 1, 3, and 5 days post-incubating. The human bone marrow stromal cells showed 11-17% higher cell proliferation than fibroblasts at each time interval. The levels of type I collagen in the human bone marrow stromal cell group was also significantly higher than those in the fibroblast group. The results indicate that the grafts of human bone marrow stromal cells can show more promising effect than that of fibroblasts for healing of chronic wounds.

The human body is structured as sentence of healing. This study examines how the mechanism of healing works in the human body by the narrative relation of functor and argument. So, we predict the way of extreme healing by literary or human narrative. For this purpose, we analyze the principle that the emotional and semantic arguments are called by the functor set by the sentences containing the fingerprints of mind in Gosijo and the mechanism of healing works extensively. We analyze the process of the transition from the narrative of the literary to the narrative of the human body. Thus, the barcode of the healing, which is made up of the relationship between the functor of the literature and the argument, is transferred to the human body and it is judged that the fingerprint of the human mind is operated through the stage of encoding and re-encoding due to the action potential. In addition, it was predicted that the neurotransmitters such as dopamine and the secretion of hormones would be promoted and the healing level would be increased. In results, we conclude that the function of argument and functor which contains the fingerprint of the mind in the third sound step on the last sentence of Gosijo is transferred to the human body and is especially heavily focused and operate with healing.

Our study attempt is to see organizational performance according to the differences between types of hospital cultures. To determine theoretical relationship between the organizational culture and the performance, we select two hospitals in Pusan which are different in the purposes and shapes of establishment. We surveyed their members on a questionnaire based on the type of the organizational culture of the two institutions, analyzed, and review its organizational effectiveness. For the survey with questionnaires, which had been preliminary studied to raise its validity, question forms were distributed to 528 persons in April, 1999 based on the self-responses and recollected within 48 hours. The recollection rate was high(89.96%) and the quantity of questionnaires used for our final analysis was 430(81.44%). The Cronbach Coefficient Alpha of the questionnaires was 0.742. Regarding statistical techniques for analysis of the written materials, dispersion analysis(ANOVA) was adapted to test the organizational effectiveness of the two hospitals having the different organizational cultures, and Pearson Correlation was applied to determine correlations was among all variables. T-test was performed to test organizational effectiveness based on the differences in the extent of sharing the culture, organizational committment and work satisfaction between the two health institutions. From our analysis, we obtain the following conclusions. First, concerning with organizational culture of the two hospital, one of which is a christian hospital and the other is a private foundation hospital, the former is conservative and human-oriented but the latter focuses on renovation and accomplishment. Second, the private establishment has a relatively higher organizational effectiveness that the religious hospital as a result of analyzing the extent of sharing culture, organizational committment and work satisfaction. Third, it has been found that the correlations between the extent of the sharing culture and the organizational committment, the extent and work satisfaction, and the committment and the satisfaction are respectively positive influencing organizational effectiveness, especially work satisfaction. Fourth, cultural factors by which the christian hospital is affected more positively including human relations among its members, belief, its idea of establishment, tradition, work responsibility, power, and wage. On the other hand, factors such as director's leadership, personnel management, wage, hospital regulations and department managers' management ability have been seen as negative influences in order. And fifth, for the private foundation hospital human relations among its members, wages, work responsibility, director's leadership and department managers' management ability were positive in their sequence while wages, personnel management, hospital regulations, welfare and department managers' management ability were considered as negative influences in order. As these results of this study, the higher extent of sharing organizational culture, the more increasing in both organization committment and work satisfaction, the higher the effectiveness. Although it was somewhat difficult to generalize the results whose subjects were the two hospitals only, it was obvious that organizational culture was an important influential factor of organizational effectiveness. It is questionable that the extent of sharing organizational culture, organizational committment and work satisfaction as variables affecting the effectiveness have their validity, but this study has its significance in that it provided an approaching to evaluate the organizational culture of individual hospitals making allowances for such variables related to the general activities in its hospital. We hope the results of the study could be useful for the managerial strategies of the institutions.
