Descriptive analysis and consumer acceptance tests were conducted with frozen (FCR), homemade (HCR), and aseptic-packaged (ACR) cooked rice products from two cultivars-IM and SD. FCR was prepared using a rapid freezing process, which may provide consumers with a quality similar to that of HCR. The intensity of the flavors of roasted, glutinous rice, rice cake, and rice starch and the textures of glutinousness, moistness, chunkiness, adhesiveness, and squishiness were all greater in the FCR as compared to the HCR and ACR (p<0.05) in IM and SD cultivars. The differences in sensory characteristics between the FCR and ACR were larger than the equivalent differences between the FCR and HCR. Overall consumer acceptance ratings for FCR in overall aspect, appearance, aroma, and texture were not significantly different compared to those for HCR (p>0.05); however, in most cases these factors showed significant differences when compared with ACR (p<0.05). From partial least square regression analysis, cooked rice was positively related to sweet, transparency, glossiness, roasted, glutinousness, chunkiness, moistness, glutinous rice, adhesiveness, rice shape, rice starch, and squishiness attributes but negatively related to raw rice, old rice, old rice aroma, a particle feeling, off-aroma, white color, scatteredness, slickness, size of cooked rice, and firmness attributes.

Objective: This study aimed to introduce the use of humidifier disinfectant (HD) in hospitals based on an on-site investigation. Methods: A preliminary survey and on-site investigation of HD use were conducted in 23 hospitals. Among them, one hospital without previous information on HD use was selected for a pilot investigation; 22 hospitals were selected based on previous documents and exposure statements from parliamentary investigation and exposure assessment regarding HD. Descriptive statistics were used to present distribution and characteristics of HD purchase and HD use in hospitals. Also, details on interviews from the on-site investigation were described. Results: Among the 23 hospitals, a total of ten were confirmed to have purchased and used an HD (nine hospitals) or HD-like product (one hospital). For the purchased HD products, four hospitals reported ‘Aekyung Gaseupgi Mate’, two hospitals reported ‘Oxy Ssakssak New Gaseupgi Dangbun’, and one hospital reported ‘Homeplus Gaseupgi Chungjungje’ (one hospital used three kinds of HD products). One hospital reported an HD-like product and four hospitals were ‘Unknown’. For the number of HD products purchased, five hospitals reported ’100 or less’, two hospitals reported ‘More than 100’, and three hospitals were ‘Unknown’. For each of the ten hospitals, we described detailed characteristics of HD purchase and its exposure status obtained through on-site investigation, including the purchase volume (i.e., number of products), exposure space (i.e., patient’s room, staff space), and exposure period. Additionally, a comparison of on-site investigation and parliamentary investigation or exposure assessment regarding HD was reported. Conclusion: This study introduced detailed cases of HD purchase and HD use in hospitals based on an on-site investigation, and our findings revealed a possibility of a considerable volume of HD exposure in various multi-use facilities, including hospitals.
도시와 농촌노인의 식생활 태도 및 영양소섭취실태 비교연구 : Urban and Rural Elderly

The dietary practices of the elderly residing in urban and in rural communities were assessed in terms of health status, dietary attitudes, eating habits, and dietary nutrient intakes. The subjects were fifty-six persons over sixty residing in the urban community of Seoul, and their rural counterparts were eighty persons residing in the rural community of Iksan-Kun, Chollabukdo. The health status of the elderly was generally good, but poor eating habits were found more frequently on the rural elderly than among the urban dwellers; several dietary nutrient intakes were insufficient. Contrasting the urban elderly with the rural group, it was found that the urban group lacked sufficient vitamin A and vitamin C and the urban women had insufficient calorie, whereas the rural group was deficient in protein, vitamin A, calorie, and fat. A significant relationship was found between dietary nutrient intake and health index, food habit points, self recognized health status, meal satisfaction, and economic status. An urgent need for the development of a nutrition education program for the elderly was pointed out.

Purpose: The purpose of this study was to identify factors that influence fatigue in hospitalized women cancer patients receiving chemotherapy. Methods: The participants were 117 women cancer patients receiving chemotherapy. The instruments used in this study were physical symptoms, mood state, family support, and fatigue scales for patients with cancer. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients and multiple regression with the IBM SPSS 19.0 program. Results: Fatigue showed significant correlation with physical symptoms such as side effects as well as sub-elements of mood status such as anxiety-depression, vitality, anger and family support. Fatigue-anticipating variables were found to be some sub-elements of mood state such as anxiety-depression (β=.61, t=10.40, p<.001), digestion organ factor (β=.78, t=2.54, p=.013) and pain/fatigue factor (β=.86, t=0.43, p=.045). The total variance explained was 69.7%. Conclusion: These results showed that the factors affecting fatigue were physical symptoms, and the mood state of hospitalized women cancer patients receiving chemotherapy. The results of this study provided basic materials for a nursing intervention program to reduce fatigue.

<P>Fullerene (C60), which has a unique molecular structure, was used in the preparation of crystalline organic nano-crystals. Fullerene was dissolved in toluene and this fullerene solution was mixed with water drastically. During this process, fullerene transferred from toluene to water phase. The significantly different solubility of fullerene in a toluene/water solvent system played an important role in the self-assembly of single fullerene nano-crystals, as it is called drowning-out crystallization. In addition, pH of water was controlled to carry out the interfacial transference of fullerene. An optical spectrum analysis showed that the fullerene was transferred by a hydrolysis reaction from toluene to water, depending on the pH and toluene involved in the crystal structure. During the interfacial transference, the growth of nano-scale fullerene occurred at pH > 7. Importantly, fullerene nanocrystals were formed with a mono-dispersed square structure on a nano-scale (104 nm average size and 1.03 +/- 0.24 aspect ratio) at pH 10.</P>

The purpose of this study were to develop short form versions of MacArthur-Bates Communicative Development Inventories - Korean and to discuss clinical implications. Two short versions were developed: one for 9∼17 month-olds(including 69 words and 17 object manipulation skills) and the other for 18∼35 month-olds (including 128 words and 5 grammatical items). Short versions seemed to be representative of full versions and showed developmental validity. Short versions showed concomitant validity with SELSI which is a standardized test for Korean children under 37 month-olds. Norm tables for words and criteria for object manipulation and grammaticality are also provided. M-B CDI-K short versions could be used as a preliminary screening tool to identify Korean children with language impairment economically and efficiently. Cautions using short versions of M-B CDI-K are discussed.

<P>We explored the use of molecular genetic biomarkers for endocrine disruption in Daphnia magna after the exposure to fenoxycarb (FOC), a model juvenile hormone analog. For this purpose, the mRNA expression patterns of DMRT93B (DMRT, sex determination), cuticle 12 (CUT, molting), and vitellogenin (VTG, embryo development) were determined in D. magna. Furthermore, these results were compared with developmental abnormality and reproduction performance. The fold changes of CUT and VTG mRNA expression showed significant dose-response relationship with FOC exposure. Relative mRNA expressions of DMRT and CUT showed notable changes at as low as 1 ng/l FOC. After chronic exposure FOC significantly delayed the first day of reproduction and decreased the number of young and growth rate even at 10 ng/l FOC. A concentration-dependant trend in reproduction effect was also observed. Developmental abnormality such as poorly developed second antennae and curved or unextended shell spines were observed. These results suggest that the three mRNAs, i.e., DMRT, CUT, and VTG can be used as biomarkers of endocrine disrupting effects in D. magna.</P>
