  • What is the "new paradigm"? It is impossible express it in one or two words, but if one had to; the closest might be the "holistic approach". The expression can be justified by the fact that the conclusions above lead to a greater intermixing of mathematics with engineering and natural sciences subjects, typically expressed in the form of examples of simplified real problems. They also lead to a greater intermixing of subjects within mathematics so that the courses should have less separation e.g. between symbolic and numerical mathematics. The conclusions also lead to the spreading the mathematics courses throughout all study years, not just the first two years. Of course, this should be done with great care in order to guarantee studies that are logically linked together. The new paradigm also means that the needs arising from industrial mathematics must be taken into account in the contents of engineering mathematics courses. Such topics are e.g. multivariate methods, statistics and use of mathematical software. What are we expected to gain from the paradigm shift? The primary benefit should be in obtaining more productive engineers equipped with a better degree of mathematical preparedness for engineering problems. But in addition, it should also promote more intensive use of applied mathematics and easier communication with professional mathematicians, often needed in complicated industrial problems.?Finally, it can be noted that the new paradigm is in harmony with the basic ideas of the CDIO (Conceive - Design - Implement - Operate) initiative for producing the next generation of engineers [1]. New ideas for engineering education can be found also in the homepage of SEFI (European Society for Engineering Education) [2].

  • In order to stabilize the price of fresh ginseng by extension of seasonal variation and marketing structure, and to reduce the cost of production by works of intensive and short term, studies were carried out. As fresh ginseng of 4 years old by the MA and CA was stored for 12 week at 4$^{\circ}C$, samples were collected after every 1, 2, 3, 4, 6, 8, 12 weeks for processing red ginseng. Color and Sensual characteristics on ginseng steamed red for the quality evaluation are summarized as follows. For the time course of storage with red ginseng, which was processed from fresh one after various treatments, L and b values were decreased, however a value was increased. In particular, absorbance was step-wisely increased. Turbidity was somewhat increased, and non-treatment of preservative were shown 2 times higher of absorbance. Extraction ratio of ethanol-soluble extractives slightly increased by the preservation methods, and as storage period was passed. CA storage and preservative treat merit versus MA and non-preservative treatment gave much stability in ginseng quality. In the sensual characters, sour taste and sweet taste were increased, but fresh taste and rice scorched taste were decreased. Bitter taste was not much changed until end of storage. CA was shown smaller differences than MA in the pH change. Addition of preservative extended the storage time.

  • The purpose of this study was to investigate diversity in the situations of multicultural families regarding the education of their children and to suggest rational ways of educating children in multicultural families. The participants in this study were 16 mothers from multicultural families typically characterized by an international marriage in which a Korean male had married a non-Korean female. The data were collected using intensive interviews over a course of three months and were analyzed by grounded theory. The results of this study showed that the participants had difficulty in adapting to the styles of educating children in Korean families and that they could not help their children do homework by themselves due to the limited personal relationships, the shortage of information about educating children, and an lack of organized education programs on Korean culture and history. Thus, they solved these problems by depending on different extracurricular activities and thus incurred a financial burden to support these activities. This led to excessive amounts of time and energy to earn the money to support the activities, which gave them few opportunities to acquire information on educating children by, for example, meeting with others. This explained their dependency on different extracurricular activities so as to solve the problem of their educating children. In an effort to seek ways to break this vicious circle, this study emphasized that policies related to educating children in multicultural families should focus on helping multicultural families strengthen their abilities to educate their children fundamentally.

  • The purpose of this study was investigated the effects of education for nursing concept to the nursing students who are not attended to major course of nursing education in nursing college. it is hoped that this education for nursing concept will be contribute to positive nursing conceptualization for nursing students. The data for this study obtained from 118 students in attending college of nursing Ewha womens University(1st year; 62, End year; 56). 1st year students(experimental group) was attended to the education for nursing concept by investigators and 2nd year students(control .group) did not. After then tested to two group: Pre and post test for experimental group and post test only to control group. The results obtained were as follows: 1) In experimental group, pre-test mean score was 116.19(SD 50.46) and post-test mean score was 253.02 (SD 66.56). Therefore post-test mean score was higher than pre-test mean score (p=0.0001). 2) There were different score between the experimental group and control group. Control group was higher(207.58, SD 52.42) than experimental group(116.19, SD 50.46) at the pre-test (p=0.0002), but experimental group(253.02, SD 66.56) was higher than control group. (207 58, SD 52.42) at post-test(p=0.0001). These results implied that early intensive education for nursing concept might have positive effects on nursing conceptualization for nursing students.

  • It is well known that a long-term exposure to a loud noise environment affects performance, since it distracts attention, and also is able to evoke stress accompanied by negative emotional states. The purpose of this study was to analyze dynamics of subjective and physiological variables during long-lasting (30 min) exposure to intensive white noise (85 dB[A]). Physiological signals on 23 college students were recorded by BIOPAC, Grass Neurodata systems and AcqKnowledge 3.5 software. Autonomic variables, namely skin conductance level (SCL), non-specific SCR number (N-SCR), inter-beat intervals in ECG (RR intervals), heart rate variability index (HF/LF ratio of HRV), respiration rate (RESP), and skin temperature (SKT) were analyzed on 5 min epoch basis. Psychological assessment (subjective rating of stress level) was also repeated on every 5 min basis. Regression and correlation analyses were employed to trace the time course of the dynamics of the subjective and autonomic physiological variables and their relationship. Results showed that intense noise evokes subjective stress with associated autonomic nervous system responses. However, it was shown that physiological variables endure specific changes in the process of exposure to loud white noise. Discussed are probable psychophysiological mechanisms mediating reactivity to long-term auditory stimulation of high intensity.

  • In viewing R&D as a series of activities of problem solving in the course of technological learning in developing countries, national R&D is very likely to play an pivotal role in incubating and improving industrial technology and competitiveness, especially for S&T-intensive industries, such as nuclear fuel industry. To this end, the national R&D needs to be primarily designed to reinforce technological capabilities of the country including government research institutes (GRIs), industrial firms, etc., from the initial stage of absorption as well as at the innovation stage. Based on this strategic role, national R&D performed by GRIs should provide scientific knowledge and core technologies which are required for the absorbption of foreign technology and development of indigenous technological capabilities with which domestic technological efforts are made to successfully achieve not only technological imitation but also innovation in global sense.

  • Discharge under the water is very hard and demand considerable high voltage. But specially improved electrode can generate plasma discharge to salty water with relatively low voltage. A round shape ceramic electrode having many pinholes combined with metallic one can generate plasma. 400 volt, 10 kHz and 3 micro second pulse width were applied to repeatedly running synthetic seawater with 10 L/m velocity, containing cultivated E. coli and Bacillus. As a result, 18, 94, 99.97, 100, 100 % disinfection rates to E. coli and 17.1, 17.1, 82.9, 99.4, 99.9 % disinfection rates to Bacillus subtilis were achieved to 1, 2, 3, 4, 5 times repetitive treatment respectively. In the plasma condition, the ions and electrons are separated and new kinds of components are re-synthesized by the intensive movement of the components. Especially chlorine ions are separated and recombined to residual free chlorine like HOCl, $OCl^-$. The residual free chlorine concentrations of discharged water were 0.25, 0.88, 1.39, 1.59, 1.66 mg $Cl_2$/L after 5 times treatment respectively. Another unconfirmed radical and oxidants for example, OH, $H_2O_2$, and $O_3$ can have an effect on microorganism of course.

  • Intensive taxonomical studies of the Aspergilli have long been made. Altogether 132 species and 18 varieties are recognized in the book "The Genus Aspergillus" written by Raper and Fennell (1965), in contrast to 77 species, 8 varieties and 4 mutations in " A Manual of Aspergilli" written 20 years earlier by Thom and Raper (1945). Classification of the Asperilli by Thom and Raper (1945) and by Raper and Fenell (1965). Classification of the Aspergilli by Thom and Raper (1945) and by Rapher and Fenell (1965) have been based mainly upon morphological and cultural detail both physiological and biochemical activities. In Korean there are many kinds of foods fermented natrually without the employment of selected microorganisms, and there are, of course, many different microorganisms serving in the fermentation fermented foods than other countries, the distribution and biological properties of the Asperigilli, in Korea are more variable. Taxonominical studies with 36 strains of Asperilli were based upon the examinations of morphological, cultural, and physiological characteristics. nineteen strains indigenous to Korea were selected from a lot of strains which had been isolated from meju and kokja and one strain from soil. They were identified according to the group key of Raper and Fennell. Ten strains were donated by Dr.Hesseltine of the Northern Utilization Research and Development Division in the U.S.A. From the Asp. japonicus supplied by Dr.Hesseltine, a white mutant was isolated and also studied. Two strains were donated by Dr. Murakami of the Research Institute of Brewing in Japan, and four strains came from Korean industrial companies.ndustrial companies.

  • Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a severe autoimmune paraneoplastic syndrome associated with ovarian teratomas. Most patients develop neurologic symptoms, including psychosis, memory deficits, seizures, or abnormal movements, and experience abdominal pain related to ovarian neoplasm. We present a case report of three patients diagnosed with anti-NMDAR encephalitis accompanied by ovarian teratomas at Ajou University Hospital in Korea. The patients demonstrated a different clinical course of the disease. However, upon diagnosis, all patients underwent surgical removal of the ovarian teratoma followed by intensive immunotherapy. The symptoms progressively improved following treatment. This is a case report of a rare autoimmune anti-NMDAR encephalitis associated with ovarian neoplasms, including immature teratoma.
