This research with 40 hearing impaired children was performed to find out the characteristics of the phonological processes for each age, hearing loss degree and aided threshold degree through the transcriptions. The phonological processes. of hearing impaired children are similar to those of normal children with a peculiar type of patterns in phonological processes. The results show that: (1) Between 5 and 6 year old groups the phonological processes were significantly different in palatal backing, glottal replacement and frication; between 6 and 7 year old groups the phonological processes were significantly different in velar fronting, labialization, alveolization and labial assimilation; between 7 and 8 year old groups the phonological processes, labialization, alveolization and alveolar assimilation, however 8 year old group showed more phonological processes than 7 year old group. (2) Between moderately-severe and severe hearing impaired groups, phonological processes were significantly different in the omissions of postvocalic, nasal and velar, stopping and stop assimilation. The differences of severe and profound groups were not found at all. (3) Aided hearing thresholds did not show any significant difference.

Communicable diseases have recently reemerged, with new communicable diseases continually breakmg out on a global scale; threaten the health and economics of populations. The Korean National Institute of Health carries out Field Management Training Prcgrams (FMTP) to address this problem The objectives of this study were the evaluation of the understanding and satisfaction for this program, and recommendation for improvement strategies. We conducted a questionnaire survey of 80 persons who completed the FMTP, at Dongguk University, between March 1 and November 30, 2002. The data collected was analyzed by Student s t-statistics. The understanding of the curriculum was Well in 42 (52.5%) and Moderate in 24 persons (30.0%). The satisfaction with the curriculum was Moderate in 38 (47.5%) and Good in 30 persons (37.5%). The satisfaction for the period of education was Bad for 31 persons (38.7%), which accounted for the majority of cases. The mean scores, by Likert s scale, for the understanding and satisfaction of the curriculum were 3.70 (±0.71) and 3.32 (i0.721, respectively. The mean score for the epidemiological survey was the highest for satisfaction with the course, at 3.78 (±0.62). The mean value of satisfaction for curriculum in education of period was significantly higher in health department group than in nursing department group (P<0.05). From this survey it appears the respondents were satisfied with this program. The FMTP will be systematically revised for curriculums, and effort will be required to develop controls for communicable disease, both by the government and the university.

This paper is a descriptive study that inquires about stress and self-esteem of obese children to lend assistance about understanding emotional care as weight management of children. The data collection was given by the structured questionnaire during five days, from 5th to 10th on march in 2003 at one primary school located in K-city. The subjects were 286 children in 11-12 year old children. The instruments used for this study were an Obesity-Stress Scale(Cho Yang Rae, 1997) and a self-esteem questionnaire including Self-Perception Profile(Harter, 1982). Data were analyzed with frequency, percentages, x²-test, ANOVA, Pearson correlation using the SPSS program. The results were as follows; 1. A stress of obese children was the highest among three group, which was significant of statistical data. On the other hand, self-esteem do be shown the same as the above but was not significant statistically. 2. A relation between stress and self-esteem of obese children was shown to be in inverse proportion ratio so that the higher stress was the lower self-esteem. 3. To research the differences of the stress followed by the general characteristics of children, there are meaningful differences in sex, character, factor of stress, shape of father's body and shape of mother's body. 4. To research the differences of the self-esteem followed by the general character of children, there are meaningful differences in sex, character, shape of mother's body and socioeconomic status.

Electro-optical and electrochemical properties of an conjugated cyclopolymer: Poly(9,9-dipropargylfluorene)

Yeong-Soon Gal,진성호,Ae-Ran Hyun,박영일,박종욱,임권택,이원철,남미애 한국공업화학회 2008 Journal of Industrial and Engineering Chemistry Vol.14 No.4

The conjugated cyclopolymer, poly(9,9-dipropargylfluorene), was prepared by the ring-forming polymerization of 9,9-dipropargylfluorene by (bicyclo[2.2.1]hepta-2,5-diene)dichloropalladium(II) in high yield. The chemical structure of poly(9,9-dipropargylfluorene) was characterized by such instrumental methods as NMR (1H, 13C), IR, UV–vis spectroscopies, and elemental analysis to have the conjugated polymer backbone bearing fluorene moieties. Poly(9,9-dipropargylfluorene) showed characteristic UV–vis absorption band at 307 and 324 nm and violet-blue PL spectrum at 411 nm, corresponding to a photon energy of 3.01 eV. The cyclic voltamograms of the polymer exhibited reversible electrochemical behaviors between the doped and undoped peaks. It was found that the kinetics of the redox process of polymer is controlled by the diffusion process mixed with the electron transfer process from the experiment of the oxidation current density of polymer vs. the scan rate.

This study investigates the anti-inflammatory effects of several components isolated from Rheum tanguticum Maxim. (Polygonaceae). Previously, we found that 70 % ethanol extracts of Rheum Rhizoma (Rheum tanguticum, R. undulatum, R. palmatum, R. officinale, Rumex crispus) had anti-inflammatory properties on LPS-stimulated RAW 264.7 macrophages and carrageenan-induced paw edema model. Thus, we studied five anthraquinone derivatives isolated from Rheum tanguticum, including chrysophanol, chrysophanol-8-O-Glc, 2-methoxy-4-hydroxyanthraquinone-5-O-Glc, emodin, and physcion. Chrysophanol, chrysophanol-8-O-Glc, physcion and emodin inhibited nitric oxide (NO) production at micromolar concentrations in LPS-induced RAW 264.7 macrophages. Among these anthraquinones, emodin was found to be a potent inhibitor with its IC50 (the half maximal inhibitory concentration) value of 57.23 μM. In addition, these four compounds dose-dependently reduced inducible nitricoxide synthase (iNOS) and cyclooxygenase-2 (COX-2) protein expression conducted by Western blotting analysis. Taken together, our data suggest that chrysophanol, chrysophanol-8-O-Glc, physcion and emodin from R. tanguticum showed anti-inflammatory activities through their inhibition of iNOS and COX-2 expression. Emodin was already reported to exhibit anti-inflammatory effects especially on acute pacreatitis animal model (1-3). Therefore, the further study is required to clarify anti-inflammatory mechanism of emodin in detail.

Dietary Lactose as a Potential Risk Factor for Coronary Heart Disease and Ovarian Cancer

Yeong Ran Jeong,Yoon-Bok Lee 충북대학교 동물의학연구소 2012 Journal of Biomedical and Translational Research Vol.13 No.2

Lactose is a disaccharide consisting of a glucose and a galactose. Milk is a sole source of lactose in natural food. Lactase hydrolyzes lactose into glucose and galactose that are absorbed in the intestine and utilized by body. After the weaning, lactase activity declines. Therefore, the majority of the adults have hypolactasia. The prevalence is above 50% in South America, Africa, and Asia. Lactose is consumed much as cow milk-based food products. However, it has no special nutritional importance for adults even it is suspected as a dietary risk factor for coronary heart disease (CHD) and ovarian cancer. The aim of this study is to review the evidences and to propose the possible mechanisms about the relations between lactose intake and CHD and ovarian cancer. Epidemiological studies support the connection of lactose and CHD. Several mechanisms are suggested to elucidate this connection but calcium theory is the most plausible. Galactose has been known to be toxic to ovary. Galactose is suggested to induce ovarian cancer through hypergonadotropic hypogonadism. Some epidemiological data support this but others do not. The consumption of lactose or galactose can induce CHD and ovarian cancer, but more research should be needed to make sure of the relation between lactose and these diseases.
