Objectives: We investigated whether oriental medical therapy influences the results of in vitro fertilization-embryo transfer. Methods: 19 women with infertility were treated by oriental treatment from August 1999 to June 2000 in the department of obstetrics and gynecology of an oriental medical center. The women were planning in vitro fertilization-embryo transfer after oriental medicine treatment. The data from the women was analyzed, we obtained the following results. Results: The average age of infertile women was $35.42{\pm}4.86$; infertility caused by male factor or tubal factor were the most frequent. The average number of previous failed IVF treatments was $2.21{\pm}1.81$. The number of aspirated oocytes was $9.00{\pm}6.09$ in IVF cycle before oriental therapy, increasing to $9.80{\pm}5.41$ after therapy, but it was not statistically significant. In IVF before oriental therapy, the average number of embryos transfer was $3.20{\pm}1.90$, and it significantly increased to $4.40{\pm}1.45$ after treatment. The quality points of embryos were $10.00{\pm}6.02$ before treatment, but statistically significantly improved to $14.07{\pm}4.98$ after. The characteristics of women being pregnant and non-successful women were compared with age, period of taking herbal medicine and the number of failed IVF treatments, but there was no significant difference. Conclusion: Oriental treatment before IVF could be expected to have good results in treatment of infertility.

The purpose of research is to suggest the direction of rural tourism and food products by looking at the relevance of the intrinsic motivation and food preference. Through the analysis, factors of 'leisure oriented', 'family oriented', 'relationship oriented', 'health oriented', and food preference 'cooking health', 'material function', 'local resource' and 'consume experience' were extracted. Through the correlation analysis, 'leisure and health oriented' was found to be significant with cooking health, 'relationship and health oriented' was significant with material function, 'leisure, family and relationship oriented' was significant with local resource and 'relationship oriented' was significant with consume experience. Therefore, tourists who want rest, healing and health need to provide healthy dishes, tourists who want family and leisure provide local or special dishes, and tourists who want to have a relationship with people need to provide functional foods or herbal medicine dishes. Food products that meet the needs of tourists will induce revisit by increasing tourist satisfaction and bring economic revitalization of the region through the expansion of rural tourism.

Objective : This study was designed to investigate anti-oxidative, anti-aging and anti-inflammatory activities of Zingiber officinale Roscoe water (ZD) and 50% ethanol extracts (ZE). Method : The antioxidant capacity of ZD or ZE was analyzed by DPPH, ABTS scavenging activities and reducing power, respectively. The anti-aging efficacy was performed with tyrosinase and collagenase inhibition activities. The anti-inflammatory activities were confirmed through inhibition of nitric oxide production and TNF-�� expression in LPS-treated Raw 264.7 cells. Result : As a result of measuring DPPH and ABTS radical scavenging activities, both ZD and ZE extracts increased in concentration-dependent manners. The ABTS radical scavenging activities of water and 50% ethanol extract were similar to that of positive control at high concentration. On reducing power, both ZD and ZE showed higher activities than the positive control at high concentration. On inhibition activities of tyrosinase and collagenase both ZD and ZE showed the large inhibition rates at low concentration. Also, the inhibitory efficacy of ZD on NO and TNF-�� production was better than ZE in RAW 264.7 cells. Conclusion : These results suggest that ZD and ZE have anti-oxidative, anti-aging and anti-inflammatory effects in vitro. Especially, ZD was more effective than ZE. Thus, Ginger extract is considered to be highly useful as a cosmetic or food material with anti-oxidative, anti-aging (prevention of whitening and wrinkle) and anti-inflammatory effects. Also these effects may vary depending on the extraction solvent.

Objectives : This experimental study was performed in order to investigate the antibacterial effect of bio-fermented Galla Rhois extract. Methods : The Galla Rhois extract was fermented by Streptococcus thermophilus, Saccharomyces cerevisiae and Lactobacillus delbrueckii, and their products was tested for antibacterial activity against six pathogenic microorganisms namely, Bacillus cereus, Bacillus subtilis, Staphylococcus aureus, Vibrio parahaemolyticus, Escherichia coli and Salmonella typhimurium by paper disc diffusion method. Results : The Galla Rhois fermented extract by Lactobacillus delbrueckii and Saccharomyces cerevisiae showed more effective antibacterial activity than not fermented extract against Bacillus subtilis and Vibrio parahaemolyticus. Antibacterial activity of fermented extract using especially Lactobacillus delbrueckii and Saccharomyces cerevisiae was proved that it was good with even 2 percents concentration. Antibacterial activity of Galla Rhois extract within pH 3 to pH 7 had been safe regardless of pH but low over pH 9. The growth of Bacillus cereus, Staphylococcus aureus, and Vibrio parahaemolyticus had a tendency to decrease depend on the increasing concentration of the extract. EtOEt, EtOAc and n-BuOH fractions of the Galla Rhois extract had a high level of antibacterial activity against Bacillus cereus, Bacillus subtilis, Staphylococcus aureus and Vibrio parahaemolyticus, respectively. Surprisingly, EtOAc fractions of the Galla Rhois extract showed higher antibacterial activity against Vibrio parahaemolyticus alone. And antibacterial activity against six pathogenic microorganisms had a tendency to increase depend on the increasing concentration of the fractions of the Galla Rhois extract. Conclusions : Bio-fermented Galla Rhois extract, efficiently inhibited the growth of Bacillus cereus and Vibrio parahaemolyticus.

Objectives : 'Reconsideration about Nomenclature of Herbs Listed in the Korean Pharmacopoeia' was published by Doh and Lee with absolute misconception of nomenclature. A critical review of Doh and Lee's paper is given, to correct the confused the concept of nomenclature and to provide proper scientific name for taxa which are discussed. Methods : This paper discusses the proper usage, as mandated by the International Code of Nomenclature. Adherence to the rules described in this paper should reduce the present confusion in the nomenclature of scientific names listed in the Korean Pharmacopoeia. Results : Although Doh and Lee proposed four categories to correct the scientific names of the Korean Pharmacopoeia using available botanical databases, they failed to show how nomenclatural concepts are applicable due to misconception of legitimacy and the confusion about synonym. From a nomenclatural perspective, 'accepted name' or 'recommended name' is a subjective term which used to be employed for convenience in a certain databases or working group without nomenclatural meaning. Doh and Lee also pointed out the standardization of author citation. However, they missed the importance of author citation error such as basionym or validating authors. Conclusions : Doh and Lee were not able to solve nomenclatural problems of the Korea Pharmacopoeia due to lack of clarity on the nomenclature code. We strongly recommend that KFDA has to commence extensive nomenclatural review for the next revision of Korea Pharmacopoeia.

One of the foremost environmental challenges, alongside the contemporary focus on achieving carbon neutrality, pertains to the pervasive issue of plastic waste. Thermochemical recycling technology, operating under high-temperature conditions to covert organic matter and recycle it into raw materials and energy, represents a transformative approach surpassing the conventional bounds of material recycling predominantly applied in plastic waste management. The thermochemical recycling paradigm is emerging as a pivotal technology within the circular economy, capable of transforming waste plastics into raw materials for producing original plastics. Its significance extends beyond national borders, garnering global attention due to its versatility as a chemical or energy recycling method, contingent upon the subsequent processes and final products. This study aims to scrutinize three quintessential thermochemical recycling technologies: combustion, gasification, and pyrolysis. Furthermore, the study discusses the recent major technology trends of these technologies.
