The purpose of the study was to investigate the perception and preference of chungkukjang in the middle school students under school meal service. For the investigation, 538 third-grade students in Seoul area were surveyed by a questionnaire and the data were analyzed by the SAS package. The result showed that 81.3% of the surveyed students responded the awareness of chungkukjang, and the motives of their interest in chungkukjang were through home education(60.0%) and mass communication(30.9%). Most students recognized that chungkukjang is the soybean fermented food, healthy food and Korean traditional food. 33.8% of students responded that chungkukjang jjigae served at the school meal service was not tasty. It also revealed that male students had more preference for chungkukjang jjigae than female students. Among the 22 kinds of new chungkukjang menu served at the school meal service in the future, 10 kinds of menu (chungkukjang samgeobsal gui, samgeobsal chungkukjang bockum, chungkukjang sauce dakk gui, chungkukjang dongasmali, chungkukjang sogogi janggug, chungkukjang kimchi bokgumbab, chungkukjang bajirak kalguksu, chungkukjang kimchi buchim, chungkukjang sangsun gut, chungkukjang bibimbab) were highly preferred foods by male students. Therefore, in order to make middle school students take the chungkukjang foods with pride by increasing their perception and knowledge of them, the family should give them many opportunities to eat chungkukjang foods. The school also should try to use more chungkukjang foods in the school meal service, and try to improve in cooking process to make more tasty chungkukjang foods fur teenagers.

Objective: Online pharmacies were introduced in some countries such as United States of America or Canada. They can provide benefits to consumer because they can buy and take conveniently drugs without limitation of location or time. In Korea, online pharmacies are illegal and only pharmacists can sell drugs to consumers or patients. Therefore, we investigated the knowledge of online pharmacy and the possible problem in Korea to survey pharmacists. Methods: We developed questionnaire based on previous articles about online pharmacy and surveyed nation-wide pharmacists by mail or e-mail. The data was analyzed by SPSS and Microsoft Excel. P-values less than 0.05 were statistically significant. Results: 175 pharmacists involved in this study. About introduction of online pharmacies, 53.1% were opposition while 10.3% were approval and 36.6% were conditional. Although online pharmacies were introduced, 46.3% pharmacists do not have a plan to start online pharmacy. However, the approval and tends about starting online pharmacies were higher in younger pharmacists (20s, 30s) (p < 0.05). The criteria of permission about opening online pharmacies were 100% pharmacist license regardless of holding off-line pharmacy. 53.7% pharmacists responded education about taking medication is impossible. When online pharmacies are introduced, 65.1% pharmacists responded traditional pharmacies are affected negatively. Pharmacists concerned that the competition with large-sized distribution corporations, reduced reliance between pharmacists and patients, illegal transaction of counterfeit drugs, increased misuse of drugs. Conclusion: These results showed that Korea pharmacists have negative standard on online pharmacies. Therefore it is required to be more cautious before introducing online pharmacy and it need strict watching system and continuous education and study for safety after introducing online pharmacy.

Imperata cylindrica, a tall tufted grass which has multiple pharmacological applications is one of the key ingredients in various traditional medicinal formula used in India. Previous reports have shown that I. cylindrica plant extract inhibited cell proliferation and induced apoptosis in various cancer cell lines. To our knowledge, no studies have been published on the effect of I. cylindrica leaf extract on human oral cancers. The present study was undertaken in order to evaluate the anticancer properties of the leaf extract of I. cylindrica using an oral squamous cell carcinoma cell line SCC-9 as an in vitro model system. A methanol extract from dried leaves of I. cylindrica (ICL) was prepared by standard procedures. Effects of the ICL extract on the morphology of SCC-9 cells was visualized by microscopy. Cytotoxicity was determined by MTT assay. Effects of the ICL extract on colony forming ability of SCC-9 cells was evaluated using clonogenic assay. Cell cycle analysis was performed by flow cytometry and induction of apoptosis was determined by DNA fragmentation assay. The ICL extract treatment caused cytotoxicity and induced cell death in vitro in SCC-9 cells in a dose-dependent manner. This treatment also significantly reduced the clonogenic potential and inhibited cell proliferation by arresting the cell cycle in the G2/M phase. Furthermore, DNA fragmentation assays showed that the observed cell death was caused by apoptosis. This is the first report showing the anticancer activity of the methanol extracts from the leaves of I. cylindrica in human oral cancer cell line. Our data indicates that ICL extract could be considered as one of the lead compounds for the formulation of anticancer therapeutic agents to treat/manage human oral cancers. The natural abundance of I. cylindrica and its wide geographic distribution could render it one of the primary resource materials for preparation of anticancer therapeutic agents.

The medical treatment is process of collecting symptoms, making a diagnosis and treatment for the diagnosis. The remedy and the efficacy are the important hinge that links the diagnosis to the means of medical treatment. Lots of medical data are stored on database or saved as files in these days. The preferential way to find the efficacy related to the remedy is search all efficacy terms match up to the remedy term. To increase the rate of matching remedy terms with efficacy terms, we study the relation between efficacy terms and remedy terms and research the conversion way of the terms into the representative terms. The rate of matching the raw remedy terms with the raw efficacy terms is below 30%. The rate of matching the disaggregate remedy terms with the disaggregate efficacy terms is about 50%. The rate of matching the representative remedy terms with the representative efficacy terms is almost 70%.

This study was carried out to investigate the perception, preference and usage of Korean festival foods of women according to age in Busan. The survey was conducted from October 15, 2012 to November 30, 2012 using questionnaires and the data were analyzed with the SPSS program. In general, younger women (20~30 years old) had a lower interest in Korean festival foods than slightly older women (40~50 years old). Most of women over 40 years of age prepared Korean festival foods at home, but many who were in their 20's (45.9%) and 30's (41.1%) obtained their foods from family and relatives. Overall, 62.5% of the subjects wanted to inherit Korean festival food from family and relatives. The dissemination of information and recipes of Korean festival foods were needed for succeeding to Korean festival foods. The taste score was significantly lower for women in their 20's compared to those over 40. Women under 40 reported a lower ease of cooking compared to women over 50. Tangguk (4.93) on Seollal showed the highest perception degree in the order of Namul (4.91), Tteokguk (4.90), and Sikhye (4.90). Jeon, Yaksik, Sikhye, and Gangjeong were the most highly preferred in every group. The preference degree of Pajeon was significantly higher in women under 40 than in those over 60. Tteokguk and Tangguk were more highly preferred in women in their 30's and 40's compared to the other groups. There was a significant positive correlation between preference for festival food and education level, degree of knowledge, degree of interest, will for inheritance, and will for learning (P<0.01). In conclusion, festival foods rich in local tradition should be developed, publicized and used to educate others. The simplification of cooking methods and the development of processed foods are needed to pass on the traditional food culture of Busan.

Over the last couple of years, traditional VANET (Vehicular Ad Hoc NETwork) evolved into VANET-based clouds. From the VANET standpoint, applications became richer by virtue of the boom in automotive telematics and infotainment technologies. Nevertheless, the research community and industries are concerned about the under-utilization of rich computation, communication, and storage resources in middle and high-end vehicles. This phenomenon became the driving force for the birth of VANET-based clouds. In this paper, we envision a novel application layer of VANET-based clouds based on the cooperation of the moving cars on the road, called CaaS (Cooperation as a Service). CaaS is divided into TIaaS (Traffic Information as a Service), WaaS (Warning as a Service), and IfaaS (Infotainment as a Service). Note, however, that this work focuses only on TIaaS and WaaS. TIaaS provides vehicular nodes, more precisely subscribers, with the fine-grained traffic information constructed by CDM (Cloud Decision Module) as a result of the cooperation of the vehicles on the roads in the form of mobility vectors. On the other hand, WaaS provides subscribers with potential warning messages in case of hazard situations on the road. Communication between the cloud infrastructure and the vehicles is done through GTs (Gateway Terminals), whereas GTs are physically realized through RSUs (Road-Side Units) and vehicles with 4G Internet access. These GTs forward the coarse-grained cooperation from vehicles to cloud and fine-grained traffic information and warnings from cloud to vehicles (subscribers) in a secure, privacy-aware fashion. In our proposed scheme, privacy is conditionally preserved wherein the location and the identity of the cooperators are preserved by leveraging the modified location-based encryption and, in case of any dispute, the node is subject to revocation. To the best of our knowledge, our proposed scheme is the first effort to offshore the extended traffic view construction function and warning messages dissemination function to the cloud.
