We investigated the physicochemical and antioxidant activity characteristics of tomato porridge with different ratios (0%, 2%, 4%, 6%, and 8%) of tomato powder in order to determine its potential health benefits. Tomato porridge samples were measured to obtain 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging activity. The DPPH radical scavenging activity increased with the addition of tomato powder. The moisture contents of samples ranged from 81% to 78%. The L-value decreased, while a- and b-values increased, as the amount of tomato powder in the porridge increased. Also, the pH of samples decreased with increasing quantity of tomato powder. Based on sensory evaluations, the tomato powder intensified color, flavor, taste, appearance, viscosity and overall acceptability of the porridge. The sample that comprised 6% tomato powder had the highest color, flavor, taste, appearance and overall acceptability scores. Consequently, this research found that incorporating this percentage of tomato powder into the rice flour was the best formula for tomato porridge.

1. Objectives: This case study described a process of the patient diagnosed as acute hepatitis A treated by medication based on the Sasang Constitutional Medicine and acupuctural theraphy and obtained improved effects about several symptoms. 2. Methods: We diagnosed the male patient with acute hepatitis A as Tae-Eumin Exterior-Cold-Disease by the Cold in the Esophagus, and administered Mahwangbalpyo-tang and Handayeolso-tang according to clinical progress. And we evaluated the results by liver function test(LFT; AST, ALT, $\gamma$-GTP ), total bilirubin level and the visual analog scale(VAS) of symptoms. 3. Results and Conclusion: Almost symptoms (except for jaundice) at the time of admission were disappeared, and also jaundice (estimated by color of scleras and color of urine) was alleviated. Also level of AST, ALT, $\gamma$-GTP and total bilirubin decreased in laboratory test. We obtained positive effects to the therapy but we considered necessities of further comparative studies with control group.

This study aimed to investigate present status of online reference shelf and analyze access point in the home page and types of online reference sources in the university library. Data were collected by accessing home pages of 41 university libraries in the region of Seoul and Kyonggi-Do. 30 libraries had prepared reference shelf out of 41 libraries, and "User Service", "Electronic Reference Sources", or "Reference & Information Sources" were mostly used as home page menu. Types of references sources varied among libraries, and "Directories", "Dictionaries", "Statistics" or "Encyclopedias" were mostly loaded types in the reference shelf. For the enhancement of reference services through reference shelf, establishing and applying standards for evaluation, ease of access, access by subject, and continuous updates and additions of reference sources were suggested.

Zirconia ceramic fixed dental prosthesis with all-on-4 concept implants for irradiated maxilla: A case report

최은주,조혜원,Choi, Eun-Joo,Cho, Hye-Won The Korean Academy of Prosthodonitics 2017 대한치과보철학회지 Vol.55 No.2

The implant-supported fixed dental prosthesis in irradiated maxilla needs meticulous treatment planning due to low bone healing capacity. All-on-4 concept implantation can reduce the number of implants to be placed avoiding bone grafting procedure. Conventionally, prefabricated angled abutments for tilted implants have been used. However, in this case, it was replaced with computer-aided design and computer-aided manufacturing (CAD/CAM) abutment. This case report described all-on-4 concept implantation and fabrication of CAD/CAM zirconia fixed dental prostheses using CAD/CAM titanium abutments. 방사선치료를 받은 상악에 임플란트 지지 고정성 보철물을 이용하여 수복하는 것은 골치유능력이 낮기 때문에 상세한 치료계획이 필요하다. All-on-4 개념에 의한 임플란트 식립은 골이식을 피하면서 임플란트를 매식할 수 있어 유리하다. 일반적으로 경사된 임플란트에는 기성 경사형 지대주를 사용해왔다. 본 임상증례에서는 computer-aided design and computer-aided manufacturing (CAD/CAM)으로 제작된 지대주를 사용하였다. 본 증례는 all-on-4 개념에 의해 임플란트를 매식하고 CAD/CAM titanium 지대주를 제작한 다음 CAD/CAM zirconia 고정성 보철물로 수복하여 좋은 결과를 얻었기에 보고하고자 한다.

The aim of this investigation was to examine the antioxidation, physicochemical, and sensory activity of a Korean steamed-rice cake, Sulgidduk, fortified with water extracts from Moringa oleifera (M. oleifera) leaf. M. oleifera leaf extracts were added to rice powder at rations of 0.1%, 1% and 10%. To examine antioxidation properties, the scavenging activities of DPPH radicals, hydroxyl radicals, ABTS+ radicals, and ferric ion reducing antioxidant power were investigated. M. oleifera extracts significantly increased the antioxidation activities of Sulgidduk in a dose dependent manner (p<0.05). Physicochemical characteristics were measured by proximate composition, color, texture profile analysis, and sensory evaluations. As the concentration of M. oleifera leaf extracts increased, L-values and a-values significantly decreased while b-values increased. Texture profile analysis demonstrated that the control groups showed significantly higher values for hardness, cohesiveness, chewiness, and adhesiveness as compared with groups containing M. oleifera leaf extract (p<0.05). In the sensory evaluation, the sample containing 0.1% of M. oleifera leaf extract obtained the best results in overall preference. Taken together, these results suggest that M. oleifera leaf may have the potential to increase the consumer acceptability and the functionality of Sulgidduk.

In order to reduce jaw fracture accompanied by basal skull or nasal fracture, submental intubation could be generally performed. Albeit submental intubation has been widely accepted, it could develop complications such as nerve injury, glandular duct injury, and orocutaneous fistula. Here, we suggest oral intubation for overcoming complications and providing more stable surgical environment in emergency case. Under oral intubation maintaining in retromolar triangle and buccal corridor space, intermaxillary fixation was successfully underwent in 38-years-old female patient with Le Fort I fracture accompanied by pneumocephalus.

Knowledge about career patterns of women In any profession and about factors which influence these career patterns becomes increasingly necessary because of the influx of ever-increasing numbers of women into the labor force, and the need for the development and utilization of the creative productivity of women. This study alms to investigate Korean female librarians' overall career patterns and verify relevant factors which might affect to their career patterns. As an instrument, self-reported questionnaires were sent to 1,251 full-time Korean female librarians throughout the country with regular librarian's certificate, currently engaging in public, college or university, and special libraries. Based on the data gathered, the interrelationship between their career pattern inclination and its influential factors were examined through hypothesis testing. Major findings of the survey are outlined in the following: 1). Female librarians' career patterns were classified into five categories with the group represented as Categories-2 (single; wishes to continue working after marriage; places an emphasis on the sense of occupational accomplishment and social prestige) accounted for the highest proportion$(33.4\%)$. 2). The result of the hypothesis testing revealed that there is no significant relationship statistically between social factors(parents' socio-economic status, etc.) and female librarians' career patterns. So the hypothesis concerning social factors were rejected. 3). In psychological factors(job satisfaction ; self-concept sex role attitude ; role conflict ; and achievement motivation), all except for self-concept were shown to be relevant with female librarians' stable career pattern. So the hypotheses concerning psychological factors were supported. 4). According to the result of multiple discriminant analysis conducted between the above four statistically significant psychological factors and career patterns, the most influential factor for female librarians' career patterns was job satisfaction and sex role. In conclusion, the following recommendations were made: For overall enhancement of Korean female librarianship, earlier career guidance and concrete sex role education for young women is urgent which enable them to establish correct viewpoint for their occupational career female librarians themselves' constant endeavor In maintaining positive attitude toward their job is required.
