As the developing of the perinatal medicine, the survival rate of preterm infants are increasing. Viceversa the children with cercbral palsy is increasing also compare to the developing of the perinatal medicine The purpose of this study was to identify the relationship between the preterm infants and the children with cerebral palsy and their domestic circumstance in 1980 and 1990. And would like to introduce the way how to handle the children with cerebral palsy

The amount and diversity of tobacco pathology research in Korea depend on the change of tobacco cultivation area. Also, the tobacco pathology research was highly influenced by the scientific development of general plant pathology during the period from 1970's to 1990's. Since 1990, the rapid decrease of the tobacco cultivation area resulted in significant decrease of the research manpower. Thus, I dare to foretell few novel studies on tobacco pathology in near future. This review summarizes a research history of tobacco pathology, at which it was once flourished in Korea.

We have studied the issues of the current math war in America. Traditionalists and the reformers have been arguing about the curriculums, teaching methods, use of calculators, basic skills, and assessment methods in K-12 mathematics. They both have strengths and weaknesses depending on the situation have contributed for the development of mathematics education. Instead of choosing between traditionalists and the reformist sides, we suggest to adopt an eclectic view point i.e., rigor and creativity, memorization and understanding that may seem at odds with each other are quite compatible and mutually reinforcing. Also teacher's deep knowledge in mathematics is extremely important as his/her knowledge in pedagogy.

A method is described for the selective functionalization of calix[4]arene at the para positions of the phenyl rings. The diametrically substituted calix[4]arene dimethyl ether 3, obtained from the treatment of calix[4]arene 2 with methyl iodide in the presence of $K_2CO_3$, is converted to the diacetyloxy calix[4]arene dimethyl ether 4. This compound undergoes Fries rearrangement to yield the diametrically p-diacetylcalix[4]arene dimethyl ether 5 in 68% yield.

The electrochemical reduction and electrogenerated chemiluminescence (ECL) of $Ru(bpy)_3^{2+}-S_2O_8^{2-}\;in\;CH_3CN-H_2O$ solution were studied in the presence of sodium dodecyl sulfate (SDS) as an anionic surfactant. SDS enhanced the ECL and the fluorescence intensities and lengthened the duration of ECL due to the solubilization of reactants and possibly to the stabilization of ECL intermediates in the SDS micellar environment.

Complexes of the type[Co(T)(L-pro)], where T is the quadridentate $N_2O_2$-type ligand, N,N'-dimethylethylenediamine-N,N'-diacetate or N,N'-dimethylethylenediamine-N,N'-di-$\alpha$-butyrate, have been prepared. The complexes were separated into the two stereoisomers, $\Delta$-s-cis-[Co(T)(L-pro)] and $\Lambda$-s-cis-[Co(T)(L-pro)]. They were characterized by their proton magnetic resonance, absorption and circular dichroism spectra, elemental analyses.

Air quality issues in Korea rapidly changed at the beginning of the 1990s from primary to secondary pollutants starting in Seoul, the capital of Korea. The present frame of national air pollution monitoring networks was established between the end of the 1980s and the beginning of the 1990s. Background monitoring was initiated in the middle of the 1990s in response to increasing public concern about the long-range transport of air pollutants. Apart from the national monitoring, both routine and intensive measurements of fine particles have been made for research purposes since the middle of the 1990s at several background sites. However, air pollution monitoring in urban areas for other purposes was relatively scarce as national monitoring has been concentrated in these areas. Although ozone pollution has become a significant issue in major metropolitan areas every summer, only a little information on ozone precursors is available. During the past few years, the number of national monitoring stations has greatly increased. The government has a plan to gradually expand monitoring items as well as stations. It is anticipated that highly detailed information on both photochemical reactants and products will be available within the next several years. More emphasis will be placed on toxic substances based on risk assessment in monitoring for both research and policy making.

Asia has shown a tendency that a certain country's culture leads the fashion in turn every 10 years. The trend of Hong Kong movies in 1980's was called 'Hong Kong Wave', the trend of Japanese animation and games in 1990's was called 'Japanese Wave', and then the 'Korean Wave' began in the late 1990's. This term '~Wave(流)' is a Japanese-style term meaning '~way', '~style', '~group', and so on. In the same manner, recent popularity of Taiwanese TV dramas and a particular star that is in fashion in Japan are called 'Taiwanese Wave', and Chinese movies, broadcast, tourism, and etc. are called 'Chinese Wave'. Thus, the term 'Korean Wave' is a part of expression '~wave' used in Japan and it started to be used in the mean time, and was officially used in <韓流-Song from Korea>, a promotion record of Korean pop music, produced by Ministry of Culture and Tourism in Korea. In this paper I propose to correct the error of the term 'Korean Wave', and furthermore, to define a term expressing Korean culture and study for its usage.

Objectives Research suggests that content of delusion and hallucination in schizophrenia is influenced by culture and social environment. However, few studies investigated chronological change of delusions and hallucinations within a society. To investigate changes in delusions and hallucinations of schizophrenia according to time, we compared contents of symptoms between inpatients with schizophrenia at two different time frames. Methods All admissions to a psychiatric unit of Hanyang University Guri Hospital with discharge diagnoses of schizophrenia at two different five-year time frames (1996-2000 and 2006-2010) were reviewed. Using a checklist, adapted from the Scale for Assessment of Positive Symptoms, we investigated delusions and hallucinations of 247 patients (104 in the 1990s and 143 in the 2000s). Results Delusions and hallucinations of patients did not differ at two time frames. In women, however, auditory and somato-tactile hallucinations were significantly more frequent in the 1990s (p < 0.05). Conclusions Our findings support the literature emphasizing that content and frequency of hallucination may differ according to cultural environment. We speculate that attitude toward sex and defensiveness toward disclosure of symptoms may have contributed to interval difference.

In this study, the number of theses conducted in 1990's for the master's degree in mathematics education was investigated in terms of their fields and themes. These theses were analysed as to how much they had been studied according to the field and whether they had conformed to the expectations and requirements for research in mathematics education under the current educational curriculum. Futhermore, this study aimed to discover advancing directions of research in mathematics education. The results are as follows: First, the rate of annual thesis presentations decreased as many as 3.82% in 1994 compared with the previous year, but the rate increased steadily in the other years showing an overall annual average increase of 8.41%. Second, in the geographical distribution of thesis presentations among local provinces, Seoul represented the highest frequency at 41.13% and Cheju Island the lowest at 1.68%. When the annual thesis presentations were analysed among regions, their number increased steadily in Seoul, but fluctuated in most other regions. Third, regarding study themes, theses on mathematics education formed 70.91% of the total while those focusing on pure mathematics formed 29.09%. Among the theses of mathematics education, most were based on teaching curriculums and the least were based on education assessment. Among the theses on teaching curriculum, teaching analytics formed the highest rate. Theses on education technology, such as computerizing and computing, have shown to be increasing annually and formed 8.95% of the total in 1999. The study also indicated that especially in the late 1990's, there have been many designed programs based on the Web, like JAVA and CGI, and studies on teaching and teaming methods using the internet.
