Sixty two out of the sixty four species of fungal isolates tested could produce both $exo-{\beta}1,4-gluconase\;(C_1)$ and $endo-{\beta}1,4-gluconase\;(C_x)$ on pure cellulose and rice straw as carbon source in Czapek's medium. Fifty-eight and fifteen species were able to grow at $25^{\circ}C$ and at $45^{\circ}C$, respectively. Eleven species could grow at both $25^{\circ}C$ and $45^{\circ}C$ while, four species appeared only at $45^{\circ}C$. The most cellulolytic species at $25^{\circ}C$ was Trichoderma koningii producing 1.164 $C_1$ (mg glucose/1 ml culture filtrate/1 hr) and 2.690 $C_x$ on pure cellulose, and 0.889 $C_1$, and 1.810 $C_x$ on rice straw, respectively. At $45^{\circ}C$, the most active thermotolerant species were Aspergillus terreus, followed by A. fumigatus. Talaromyces thermophilus was the highest active thermophilic species followed by Malbranchea sulfurea. Most of these species were also active in fermentation of rice straw at 25 and $45^{\circ}C$ (P<0.05). The most active ones were T. koningii, A. ochraceus and A. terreus, which produced 201.5, 193.1 and 188.1 mg crude protein/g dry straw, respectively.

The purpose of this study was to analyze the satisfaction level on hospital foods in elderly and middle aged patients. The subjects were selected among the patients treated in the Inha University hospital during July of 1999. One hundred thirty five elderly patients aged over sixty(68 men, 67 women) and sixty five patients aged in forties(35 men, 30 women) were surveyed through questionnaires in terms of satisfaction level on hospital foods and the food preferences. Satisfaction on general taste, saltiness, serving temperature, appearance, texture and variety of hospital foods was not significantly different according to age. However, elderly men showed significantly higher satisfaction level than elderly women in terms of general taste of hospital foods(p<0.01). The preferences of cooking method for meat, fish, vegetable and the preferred kinds of kimchi and milk & milk products were not significantly different between the two age groups. However, elderly women significantly preferred sauted meat to broiled meat compared to elderly men(p<0.05).

The Gwangalli Beach, one of beaches representative of Busan together with the Haeundae Beach, is a tourist attraction, having increased tourists since the completion of Gwangandaero Bridge in 2003 and recording more than 10 million tourists in 2006. Although the competent local government office has conducted artificial beach nourishment/gravel removal projects every year to manage it, systematic monitoring and studies of erosion are insufficient. This study analyzed the changes in the coastline of Gwangalli Beach using aerial photos, tidal data, GPS survey data for the last sixty years, and examined how the Gwangandaero Bridge, which had been constructed on the Gwanganlli sea, has affected the changes. The results show that the area of Gwangalli Beach has increased 40% for the last sixty years, and that the effects of Gwangandaero Bridge on the coastline are insignificant.

Purpose: This study examined the hip and lumbopelvic movement while the hip was rotating laterally in individuals with chronic low back pain (CLBP). Methods: Sixty healthy subjects and sixty subjects with CLBP were enrolled in this study. Myomotion (Myomotion research pro, Noraxon Inc., German) was used to measure the hip lateral rotation and the lumbopelvic movement. An independent t-test was used to compare the hip lateral rotation and lumbopelvic rotation between the groups. Results: Between healthy males and females, healthy females showed a smaller hip lateral rotation angle (HLRA) than healthy males in the hip lateral rotation test (HLRT). Between the healthy females and females with CLBP, the females with CLBP showed a smaller HLRA and greater lumbopelvic motion than the healthy females in the HLRT, and their lumbopelvic motions occurred earlier during lateral rotation of the hip. Finally, between the males and females with CLBP, the females with CLBP showed a smaller HLRA and greater lumbopelvic motion in the HLRT, and their lumbopelvic motions occurred earlier during lateral rotation of the hip. Conclusion: The results of this study suggest that the CLBP affected the hip lateral rotation, and the lumbopelvic movement depended on gender. In particular, compared to the other groups, the females with CLBP showed a larger lumbopelvic rotation angle and smaller hip lateral rotation angle and lumbopelvic motion occurred early during lateral rotation of the hip.

This research presents author co-citation analysis of the subject area in the humanities - Korean history. Three approaches to multivariate analyses were used to display the inter-author relationships in the similarity matrix. Data on co-citation of sixty seven authors for the period of 1980­1989 were extracted from the database constructed by author. The author's name, here refers to a body of writings by a person, is the unit of analysis. The data were subjected to non-metric multidimensional scaling program create two-dimensional map of authors. Authors with similarity are clustered using hierarchical agglomerative procedure and it is found that five clusters in Korean history represent primarily research specializations. Author map of Korean history reveals the first dimension corresponding to subject orientation of authors and the second dimension corresponds to research method or research style. In factor analysis, each factor reflects research specialty made up of authors, and factor locadings demonstrate the breadth or concentration of sixty seven authors' scholarly contributions on Korean history. It is demonstrated that the· specific methodology employed by this research, author co-citation analysis, is useful to represent the intellectual structure of Korean history.

We analyzed the concentration of Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), Alkaline Phosphatase (ALP), Gamma Glutamyl Transferase (GGT), total protein (TP), albumin, total cholesterol (TC) and triglyceride in sera of patients (n=455) aged 60 years and older with hyperglycemia (${\geq}120mg/dL$ in serum). The average concentration of biochemicals in patient group was compared with those in reference group. Our data showed that the average concentrations of AST and TC in sera of senior patients with hyperglycemia were significantly increased by 27.5% (P<0.05) and 82% (P<0.05) in total group, 38.5% (P<0.05) and 75.0% (P<0.05) in sixty years' group, 16.0% (P<0.05) and 89.7% (P<0.05) in seventy years' group and 27.0% (P<0.05) and 79.5% (P<0.05) in eighty years' group, respectively. Patients with hyperglycemia showed a significant decrease in albumin level by 6.7% (total group, P<0.05), 4.5% (sixty years' group, P<0.05), 8.9% (seventy years' group, P<0.05) and 4.5% (eighty years' group, P<0.05), respectively. In conclusion, the high concentration of glucose in the senior patients with hyperglycemia may be a cause of severe liver function and lipid metabolism disorder.

To investigate the effects of facial blood flow rates(FBFR) and facial skin temperature(FST) generated by Gagam-Jawoonaek(GJ) application(appl.) after Miso Facial Rejuvenation Acupuncture(MFRA). Ten people in their twenties to fifties with no skin diseases were recruited. We randomly divided subjects two groups(A, B) and set the GJ appl. site(group A - right side, group B - left side). MFRA was performed on both sides of their face. Immediately after acupuncture treatment(AT treat.), GJ was applied only half of the face. We measured their FBFR using Laser Doppler Perfusion Imaging(LDPI) and FST using Digital Infrared Thermal Imaging(DITI) at pre-AT treat., immediately after AT treat., twenty and sixty minutes after GJ appl.. We analyzed data using Mann-Whitney test and Wilcoxon test(p < 0.05). After MFRA treat., FBFR on both sides increased. Twenty minutes after JW appl., the changes of FBFR on GJ appl. side($122.9{\pm}43.1PU$) were bigger than GJ non-appl. side($80.9{\pm}38.4PU$), a statistically significant decrease. Sixty minutes after application, FBFR on both sides were recovered almost at the same level as that of pre-AT treat. After MFRA treat., FST on both sides increased. Twenty minutes after GJ appl., the changes of FST on GJ appl. side($1.1{\pm}0.6^{\circ}C$) were comparable to that of GJ non-appl. side($1.2{\pm}0.5^{\circ}C$). Sixty minutes after application, FST on both sides were recovered almost at the same level as that of pre-AT treat.. Gagam-Jawoonaek could decrease facial blood flow rates.
