Purpose : Hysterectomy without lymph node dissection was considered an inadequate treatment method for invasive uterine cervix cancer. Usually the procedure was performed inadvertently on patients who were thought to have benign or premalignant conditions preoperatively. We analysed radiotherapy results of such patients to evaluate survival rates, failure patterns and prognostic factors according to various conditions. Materials and Methods : Sixty one patients undergoing hysterectomy in the presence of invasive cervical carcinoma were reviewed retrospectively. Preoperative diagnosis were carcinoma in situ (38 cases), severe dysplasia (2), myoma (6), uterine bleeding (4), uterine prolapse (2). and early invasive cervix cancer (10) (One patient had myoma and carcinoma in situ coincidently). Patients received postoperative megavoltage radiotherapy from August 1985 to December 1993, and minimum follow-up period was 24 months. Eight patients received ICR only, 6 patients ICR and external radiation, and 47 patients received external radiation therapy only. Results : Overall 5-year survival rate and relapse-free survival rate werer $83.8\%$, $86.9\%$ respectively. For patients with retrospective stage IA, IB, IIB (gross residual after surgery), and vaginal cuff recurrence were $90.9\%$, $88.8\%$, $38.4\%$, and $100\%$ respectively There were 8 cases of treatment failure, most of them (5/8) were in patients with gross residual disease, other patients were full thickness involvement of cervix wall (2/8) except one. Patients with early vaginal cuff recurrence and microinvasive cervical cancer (stage IA) had no treatment related failure Prognostic factors affecting survival by univariate analysis were status of residual disease, tumor histology and retrospective stage. Conclusion : Adjuvant radiotherapy appeared to be effective treatment method for patients with presumed stage IA, IB and early local recurrent disease after inadvertent hysterectomy Survivals for patients with gross disease remained after inappropriate hysterectomy was poor, So, early cancer detection and Proper management with precise pretreatment s1aging is necessary to avoid inadherent hysterectomy especially in the cases of gross residual disease.

Korean traditional rice wines and liquors have been long brewed using nuruk or koji, cooked rice, How, yeast and some medicinal plants or herbs. The rosemary shrub (Rosmarinus officinalis L), belonging to the Labiatae family, is well recognized for its aromatic, antioxidant, antimicrobial and antitumoral properties. In this study, we investigated the effect of rosemary addition on the quality characteristics of Korean traditional rice wine. Wines containing different rosemary concentrations (0, 10, 20 or 30%) were ripened for 0, 5, 10, 15 and 20 days at 25C. The following quality characteristics were compared: pH, total acid, titratable acidity, amylase activity, color, reducing sugar amount, total sugar and ethanol. Although total acid increased, the pH of rosemary wine rapidly decreased during the rot 5-days of ripening, and these two changes were greatest in the wine containing 10% rosemary. The amount of both reducing sugar and ethanol in the wine rapidly increased during the rot 5-days of ripening, while total sugar content of rosemary wine decreased significantly with increasing ripening periods(p<0.05). According to the Hunter's color results, a significant color change in 'L' value was observed with increasing fermentation period in the wine containing 10% rosemary. Although 'a' value of control (0% rosemary liquor) increased during the ripening period, the addition of rosemary did not significantly affect 'a' or 'b' values. The transmittance of rosemary wines increased with increasing rosemary content but decreased throughout the ripening periods. Amylase activity decreased with increasing rosemary content, especially after a 5-day ripening period.

This study investigated the changes in chemical components, antioxidant compounds, and activity before (BG) and after germinated (AG) brown rice in order to promote the availability of these beneficial factors. The GABA content of BG and AG brown rice were 0.07~6.61 and 11.13~49.72 mg/100 g, respectively. The ${\alpha}$-amylase activity of AG brown rice was 1.77~70.25 unit/g fold higher than it was in BG brown rice. Total polyphenol and flavonoid contents, which are known to be related to antioxidation, were higher in BG brown rice than in AG brown rice. The total polyphenol contents of BG and AG brown rice were 10.52~36.38 and 11.38~26.33 mg/100 g, and the total flavonoid contents were 3.55~13.39 and 3.52~9.78 mg/100 g, respectively. Also, DPPH radical scavenging activity was 57.64~251.34 and 50.49~213.35 mg TE/100 g, respectively. ABTS radical scavenging activity and total tannin content showed a similar trend to DPPH radical scavenging activity. We expect that this data will be useful in the manufacturing of food products.

Liparis tessellatus(cubed snailfish), Hemitripterus villosus(shaggy sea raven), Ligularia fischeri, and Cirsiu setidens, which are staple products in Samcheok, were studied as food resources for the development of a representative local menu. Thus, their nutritional compositions were analyzed, and the resulting values were used to assess the nutritional characteristics of the newly-developed menu. In Liparis tessellatus and Hemitripterus villosus, the organic components including protein and fat tended to be lower than the corresponding values referred to as the 'Seventh Revision Food Composition Table' (2006), which was presumably linked to the spawning period of the fish. The contents of Zn, Cu, and Mg, which are nutritionally important even though the consumption of these minerals by Koreans is not sufficient, were determined to 0.5, 0.2, and 34.3 mg/100 g for Ligularia fischeri, and 26.2, 1.1, and 147.7 mg/100 g for dried Cirsiu setidens. Cirsiu setidens cultivated in Samcheok contained noticeably higher amounts of calcium, zinc, and iron, and its calcium level was more than an order of magnitude higher than that provided by the Food Composition Table. This might be associated with the fact of that Samcheok is abundant in lime which consists of calcium-containing inorganic materials. n-3 fatty acids including docosahexaenoic acid(DHA) accounted for 21% and 13% of the total fatty acids, for Liparis tessellatus and Hemitripterus villosus, respectively, and the major amino acids were glutamic acid, aspartic acid, glycine, and alanine for both fish. One of the newly developed menus, Cirsiu setidens hae-jang-gook, was nutritionally superior to the corresponding menu that used dried radish leaves, a typical ingredient in hae-jang-gook, in terms of the protein, iron, and zinc contents. Rice pottage cooked with Liparis tessellatus instead of abalone was high in protein, calcium, iron and zinc, where one serving provided 29.1, 15.4, 31.0, and 27.8% of their Reference Intake (RI)s, respectively.

The aim of this study was to evaluate the quality characteristics and antioxidant activity of yogurt containing spirulina. Yogurt base was prepared from skim milk added with $0.25{\sim}1%(w/v)$ spirulina powder and fermented with lactic acid bacteria (S. thermophilus : L. bulgaricus = 1 : 1) at $40^{\circ}C$ for 12 hr. Kiwi puree and oligosaccharides were then added. The addition of 1% spirulina powder stimulated the growth of lactic acid bacteria, which showed the highest viable cell count ($3.4{\times}10^9$ CFU/mL), and increased the titratable acidity (1.10%). The viscosity range of the yogurt was 6,000 to 9,000 cP, and the sugar content of the yogurt was around 18 $^{\circ}Brix$. The antioxidant activities were determined using the DPPH method, and the hydroxyl radical scavenging activity of the yogurt containing spirulina was higher than that of the control. The sensory evaluation scores for appearance, odor, taste, overall acceptability and buying intention were higher in the yogurt containing 0.25% spirulina than in the other groups. The amount of macronutrients in the yogurt containing spirulina was higher than that in the control. In addition, the amounts of micronutrients in the yogurt containing spirulina was significantly increased. According to these results, the optimum concentration of spirulina powder is around 0.25%.

Supercritical fluid extraction of ${\beta}$-carotene from carrot was optimized to maximize ${\beta}$-carotene (Y) extraction yield. A central composite design involving extraction pressure ($X_1$ 200-,100 bar), temperature ($X_2,\;35-51^{\circ}C$) and time ($X_1$$ 60-200min) was used. Three independent factors ($X_1,\;X_2,\;X_3$) were chosen to determine their effects on the various responses and the function was expressed in terms of a quadratic polynomial equation,$Y={\beta}_0+{\beta}_1X_1+{\beta}_2X_2+{\beta}_3X_3+{\beta}_11X_12+{\beta}_22X_3^2+{\beta}_-12X_1X_2+{\beta}_12X_1X_2+{\beta}_13X_1X_3+{\beta}_23X_2X_3,$ which measures the linear, quadratic and interaction effects. Extraction yields of ${\beta}$-carotene were affected by pressure, time and temperature in the decreasing order, and linear effect of tenter point (${\beta}_11$) and pressure (${\beta}_1$) were significant at a level of 0.001(${\alpha}$). Based on the analysis of variance, the model fitted for ${\beta}_11$-carotene (Y) was significant at 5% confidence level and the coefficient of determination was 0.938. According to the response surface of ${\beta}$-carotene by cannoical analysis, the stationary point for quantitatively dependent variable (Y) was found to be the maximum point for extraction yield. Response area for ${\beta}$-carotene (Y) in terms of interesting region was estimated over $10,611{\mu}g$ Per 100 g raw carrot under extraction.

Experiments were conducted to elucidate the effects of pH change and sodium alginate, gum karaya and gum arabic on the foaming properties of soy protein isolate (SPI). The surface tensions of SPI solution (5%) adding to gums at pH 4.0 and 5.0, near the isoelectric point (pH 4.5) were higher than those at pH 7.0 and 8.0. Specific viscosity of the solutions adding to gums (0.1, 0.2 and 0.3%) at pH 7.0 and 8.0 were $3.6{\sim}51.8$ and $4.0{\sim}51.2$, respectively. In cases of addition of sodium alginates specific viscosity were predominantly increased, while those of gum arabic did not almost increase. Addition of gums reduced the overrun, but it stabilized the foams, especially those of sodium alginates (0.2%) increased the foam stability at pH 5.0, 7.0 and 8.0 by 57, 413 and 315%, respectively. Foaming ability, foam stability and heat stability of the foam were significantly (p<0.05) affected by changing pH. There was a tendency to increase the foaming ability according to the decrease of surface tension. Specific viscosity was also important in foam stability and heat stability.

Purpose : Through a clinical and retrospective analysis of pediatric patients who visited the Regional Emergency Medical Center of Masan Samsung Hospital from January 2007 to December 2008, we characterized pediatric and adolescent emergency patients to improve emergency care in future. Methods : We reviewed the medical records of 14,065 pediatric patients below 19 years of age. Results : The male to female ratio was 1.5:1, and the most common age group was less than 3 years (49.6%). The peak month was May (10.0%), the peak day of the week was Sunday (24.7%), and the peak time of day was 20:00-0:59 (8.5%). There was no difference in the number of visits per day based on weather (sunny, rain [below 10 mm per day], snow, and fog) or daily temperature difference; however, visits increased on sandy, dusty days and decreased on rainy days with more than 10 mm of rain per day. Based on the international classification of disease (ICD)-10 system, the most common disease code was code R (symptoms, sign, and abnormal clinical laboratory finding) (31.5%), and the most common symptom was fever (13.1%). Final outcomes were discharged (73.8%), admitted (25.7%), transferred (0.4%), and expired (0.1%). In adolescent patients aged 15-9 years, the most common disease code was Injury & Poisoning (code S&T, 36.9%); the most common symptom was abdominal pain (9.6%). Conclusion : Pediatric patients visiting the emergency center were most likely to be male and under 3 years of age and to visit between 20:00 and 21:00 on Sundays and in May, and the most common symptom was fever. Differences between adolescents and pediatric patients showed that adolescents had a higher visiting rate with abdominal pain and a larger temperature difference.

Rice yield and primary productivity (NPP) are dependent upon the variability of climate and soil. The variability and regionality of the rice yield and net primary productivity were evaluated with the meteorological data collected from Korea Meteorology Administration and the actual rice yield data from the Ministration of Agriculture and Forestry, Korea. The estimated NPP using the three models, dependent upon temperature(NPP-T), precipitation(NPP-P) and net radiation(NPP-R), ranged from 10.87 to 17.52 Mg ha$^{-1}$ with average of 14.69 Mg ha$^{-1}$ in the South Korea and was ranged 6.47 to 15.58 Mg ha$^{-1}$ with average of 12.59 Mg ha$^{-1}$ in the North Korea. The primary limiting factor of NPP in Korea was net radiation, and the secondary limiting factor was temperature. Spectral analysis on the long term change in air temperature in July and August showed periodicity. The short periodicity was 3 to 7 years and the long periodicity was 15 to 43 years. The coefficient of variances, CV, of the rice yield from 1989 to 1998 ranged 3.23 percents to 12.37 percents which were lower than past decades. The CV's in Kangwon and Kyeongbuk were high while that in Chonbuk was the lowest. The prediction model based on th e yield index and yield response to temperature obtain ed from the field crop situation showed reasonable results and thus the spatial distributions of rice yield and predicted yield could be expressed in the maps. The predicted yields was well fitted with the actual yield except Kyungbuk. For better prediction, modification should be made considering radiation factor in further development.
