PURPOSE. To longitudinally assess the quality of life in maxillectomy patients rehabilitated with obturator prosthesis. MATERIALS AND METHODS. Thirty-six subjects were enrolled in the span of 16 months, out of which six were dropouts. Subjects (age group 20-60 years) with maxillary defects, irrespective of the cause, planned for definite obturator prosthesis, were recruited. The Hindi version of European Organization for Research and Treatment of Cancer, Head and Neck version 1 of Quality of Life Questionnaire was used before surgical intervention and one month after definitive obturator. Questionnaire includes 35 questions related to the patient's physical health, well being, psychological status, social relation and environmental conditions. The data were processed with statistical package for social science (SPSS). Probability level of P<.05 was considered statistically significant. RESULTS. The quality of life after rehabilitation with obturator prosthesis was 81.48% (${\pm}13.64$) on average. On item-level, maximum mean scores were obtained for items problem with teeth ($1.87{\pm}0.94$), pain in mouth ($1.80{\pm}0.92$), trouble in eating ($1.70{\pm}0.88$), trouble in talking to other people ($1.60{\pm}1.22$), problems in swallowing solid food ($1.57{\pm}1.22$) and bothering appearance ($1.53{\pm}1.04$); while minimum scores were obtained for the items coughing ($1.17{\pm}0.38$), hoarseness of voice ($1.17{\pm}0.53$), painful throat ($1.13{\pm}0.43$), trouble in having social contacts with friends ($1.10{\pm}0.40$) and trouble having physical contacts with family or friends ($1.10{\pm}0.31$). CONCLUSION. Obturator prosthesis is a highly positive and non-invasive approach to improve the quality of life of patients with maxillectomy defects.

Objectives: Obesity is becoming more popular disease worldwide. Because of the side effects of conventional obesity treatment modality, herbal medicine treatment is becoming more preferred. Gambihwan which including Ephedra sinica Staph is widely used in traditional Korean Medicine practice for obesity treatment. Garcinia cambogia is a kind of health functional food that has body fat reducing effect. Nowadays, ephedra and Garcinia cambogia are often used simultaneously in clinical practice of Korean Medicine. However, the effectiveness and safety of combination therapy in obesity treatment is not well established. Methods: We conducted retrospective observational study to explore effectiveness and safety of combination therapy. We evaluated effect of combined treatment of Gambihwan and Garcinia cambogia on body weight, body mass index, body fat mass, and waist hip ratio reduction. We also assessed safety via liver function test and adverse event. Results: Finally, 23 patients were included. In paired t-test, body weight significantly decreased from 64.50±14.50 kg to 62.94±13.85 kg (P<0.001) and body mass index were also significantly decreased from 24.43±3.79 kg/㎡ to 23.83±3.59 kg/㎡ (P<0.001). Body fat mass was also reduced. Aspartate transaminase and alanine aminotransferase were not significantly increased. There were no drug-induced liver injury and no severe adverse event. Conclusions: In our retrospective review, we found combination therapy of Gambihwan and Garcinia cambogia reduce body weight, body mass index and body fat mass. There were no severe adverse event and drug induced liver injury which indicated safety of combination therapy in obesity treatment.

A medicinal herb, Stevia rebaudiana Bertoni which is grown under physical stresses such as simulated microgravity, shaking, and low temperature for 4 days, showed fresh weight decrease of 3.6%, 21% and 8.7% compared with the respective control. On control plants, the radical scavenging value of DPPH represented 86% and 55%, respectively in the leaves and stems extracts. Relatively weak antioxidant activities of 22% and 27% were measured respectively in AA (ascorbic acid) and BHA (beta-hydroxyacetic acid) known as synthetic antioxidants. The radical scavenging effect of DPPH (2,2-diphenyl-1-picryl hydazal) in stevia plants under a simulated microgravity was observed to be consistently higher relative to the control, whereas those effects of shaking and low temperature treatments rapidly increased and then reduced after 6 hours in case of shaking process and 24 hours in case of low temperature treatment, which results had similar levels of scavenging effects to the control. The plants under simulated microgravity showed the highest level of activity with the value of 147% and the shaking and low temperature treatments showed the increases of SOD activity by 121% and 125%, respectively. From the above results, it is clarified that the simulated microgravity is more effective to the antioxidant activity than those of other abiotic stresses.

Rice (Oryza sativa L.) is one of the major cereal crops for consumption by the world’s population. Recently, various colored rice, such as white, red, brown, green, and black rice, have caught the attention of world consumers. The commercial name ‘black rice’ contains a high amount of anthocyanins in pericarp, which increases nutritional value. Moreover, anthocyanin in black rice possesses biomedical properties, including anti-oxidant, anti-cancer, and anti-inflammatory effects in humans. In genetics, black rice has a dominant PURPLE PERICARP (Prp) trait governed by two genes, Pb and Pp, which are involved in the synthesis of cyanidin-3-O-glucoside (C3G). Since the publication of a report by Nagai at 1921, the genetics and physiological studies of black rice driven by Prp traits are still unable to understand the relevant genes and their roles. However, with the increased demand for anthocyanin-rich black rice as a functional food for human health, it has become urgent to develop highyielding anthocyanin-rich varieties of rice. We explored many years in the genetics of purple pericarp trait, anthocyanin biosynthesis in pericarp during seed development, and, consequently, their products in relation to different physiological and agronomic traits. In this review, we summarized the anthocyanin biosynthesis in pericarp, emphasizing the inheritance pattern of the trait and functions of their products on different physiological and agronomic traits, including the yield of black rice.

We evaluated the effect of dietary supplements with benzoic acid on intestinal beneficial bacteria concentration and immune response of weaning pigs. Supplementation with benzoic acid at 0.5% or control diet for 35 days resulted in a higher Lactobacillus casei concentration in the cecum. Supplementation with benzoic acid at 0.5% increased concentration of L. plantarum in the cecum. Pigs with the control diet and 0.5% benzoic acid had significantly increased concentration of B. subtillis in the cecum compared to the antibiotic group, while the concentration of B. subtillis in the rectum increased in pigs given 0.3 and 0.5% benzoic acid (p<0.05). Compared with the control group, the level of interleukin-$1{\beta}$ mRNA showed a significant decrease in the proximal small intestine in pigs fed diets supplemented with benzoic acid at 0.5% or antibiotic. Feeding 0.5% benzoic acid resulted in a marked reduction in the expression of IL-6 mRNA in the middle small intestine (p<0.05). Supplementation with benzoic acid at 0.5% or antibiotic resulted in a lower level of tumor necrosis factor-mRNA in the middle intestine. Up to 0.5% benzoic acid may be included in weaning diets for improvement of intestinal beneficial bacteria, thus modulating genes of pro-inflammatory cytokines in the gastrointestinal tract.

In recent years, the growing interest in the health care benefits of sugared-plant fermented enzymes has led to increased consumption. This study investigated the fermentation of sugared-buchu (Leek:sugar, 1:3) by lactic acid bacteria (Lactobacillus acidophilus AML 0422, Lactobacillus brevis HLJ 59, Lactobacillus helveticus AML0410, Lactobacillus plantarium KCTC 13093) and the antibacterial activity, antioxidant activity, and functionality (e.g., anti-hypertensive activity) of the fermented product. The fermented sugared-buchu showed high antibacterial activity against Staphylococcus aureus KCTC 1916, at 31.43 mm, and its total polyphenols, total flavonoid content, and DPPH scavenging activity were 160.8-178 mg/ml, 100-108 mg/ml, and 51.4-58.1%, respectively. DPPH scavenging activity was to that of vitamin C (50 ppm). ACE inhibitory activity was 50.4-67%, depending on the strain of lactic acid bacteria, and the control of sugared-buchu activity was higher than 32.6%. These results suggest that sugared-buchu fermented with lactic acid bacteria has strong antibacterial, antioxidant, and ACE inhibitory activities.

This study aimed at analyzing the clothing management units of technology and home economics textbooks in terms of their contents related to Education for Sustainable Development(ESD). The inquisitive tendency of the textbooks was also examined adopting the modified Romey's method, because it is known as an important factor in increasing student's class participation in sustainable clothing management and inducing practical behavior. First, the learning contents of clothing management unit were analyzed according to the social/political/cultural, environmental, and economic perspectives of ESD. As a result, ESD contents from social/political/cultural perspectives (safety, and health and food), environmental perspectives (natural resources, energy, and environmental problem), and the economic perspectives (sustainable production and consumption) were identified, with a heavy focus on environmental perspective. Secondly, Romey's inquisitive content analysis method was modified to analyze texts, pictures/charts, and learning activities of the clothing management unit. In all textbooks, facts and definitions were the dominant types of contents, which means less opportunities for development of inquiry ability. In conclusion, the ESD contents of the clothing management unit are inclined to the environmental perspective, and it is necessary that textbook development would need to be balanced between three perspectives. Also, future textbook authors will need to improve the inquisitive tendency of the textbooks to encourage student participation in class and induce practical application in real life.

Adverse drug reactions (ADR) caused by inappropriate prescription are responsible for major socioeconomic loss. Drug-drug interactions (DDI) has been recognized as a major part of ADRs and, therefore, healthcare professionals should prevent possible DDIs to minimize preventable ADRs. This study aimed to examine DDI information in drug information references and Korea Food & Drug Administration (KFDA) drug labeling information. Drug ingredients from the formulary of Health Insurance Review and Assessment Service in Korea (HIRA) were included for the study. DDI information source used for the study were Micromedex Drugdex and Drug Information Facts (DIF) with the DDI severity level of "moderate" or more. The DDI information in KFDA drug labeling were collected and compared. Drug ingredients were classified with KFDA Drug Classification and ATC Classification of WHO for the analysis. Among the total 1,355 drug ingredients satisfying inclusion criteria, 738 ingredients involved at least one DDI, which was described in Micromedex and/or DIF. Drug Ingredients of 176 involved DDI only described in KFDA drug labeling, but not Micromedex nor DIF. Drug ingredients of 35 which DDIs were described in Micromedex or DIF did not have DDI based on KFDA drug labeling. Micromedex and DIF retrieved 7,582 and 3,071 DDIs, respectively 57.6% and 58.5% of DDIs were also described in KFDA drug labeling. Central nervous system (CNS) drugs, cardiovascular system (CVS) drugs and the antiinfectives appeared to have higher frequency of DDIs among all drug classes. The highest number of DDIs with high severity level ("contraindicated" or "major") were the DDIs of CNS drugs. The antiinfectives are the second drug group having serious DDIs. The DDI pairs of the CNS drug and the antiinfective had the highest contraindication risk (13.6%). DDI information from Micromedex and DIF were not consistent with the result that only 465 ingredients' DDIs are common in both literature (total DDI numbers were 715 vs 488, respectively). And 1,652 DDI information are common in both references among 7,582 vs 3,071 DDIs, respectively. Only 55.2% of DDI information in the database contained in the KFDA drug labeling. Prescribers and pharmacists should pay attention to the drugs for CV system, CNS and infections because of higher risk of possible DDIs compared to other drug classes. KFDA drug labeling is not likely to be recommended as a good information source for DDI due to significant inconsistency of information. Drug information providers should be aware that DDI information from different sources are not consistent and therefore multiple references should be used.

This research estimates the impact of population aging on energy use and carbon emissions by energy sources and by industrial sectors in Korea until 2035. For the estimation, the structural change in household consumption expenditure identified by the age-specific consumption pattern was analyzed in conjunction with energy and environment input-output tables. The estimation result presents that, despite the population aging, energy use and carbon emissions induced by household consumption continue to increase until 2026, and then that elevated levels of energy use and carbon emissions will be maintained for a considerable period of time. According to the estimation by energy sources, the use of natural gas will show substantial increase while the use of crude oil will switch to a downturn at a relatively early period. According to the estimation by industrial sectors, carbon emissions in the sectors with relatively high consumption share of old households such as medical health, dwelling, lighting, heating, air-conditioning, and food will have substantial increase, whereas those in the sectors associated with education, transport, catering, and accommodation services will turn downward relatively early. In addition, the study analyzes through policy simulation the impact of aging-related policy similar to the basic pension system, which is recently being discussed for legislation, on energy use and carbon emissions.
