Alternative medicine is defined as the practices used for the prevention and the treatment of diseases that are not taught widely in medical schools, nor generally available inside hospitals. Alternative medicine or therapy is of growing interest to the general public. We conducted a survey to determine the prevalence and patterns of using alternative medicine such as herbal medicine acupuncture, folk medicine, health food and diet, yoga, qi therapy, shiatsu, chiropractics, homeopathy etc.. Based on 794 completed questionnaires, 484 respondents(61%) reported using at least one form of alternative medicine for their medical problems. The major medical conditions for which they used alternative medicine were back pain(85.6%), arthritis(85.4%), hypertension(85.2%), cerebrovascular disorders(86.4%), and insomnia(84.6%). The types of alternative medicine frequently used were herbal medicine, acupuncture, folk medicine, and health food. The reasons why the vast majority of people sought after alternative medicine was that: less side-effect, it is not harmful, it is more effective, there is a shorter waiting time, and a better explanation fur the conditions and a kinder therapist. We found that the frequency of using alternative medicine in the health care system was high. Physicians need to be more aware that many patients may be using alternative medicine. Further survey of the nation-wide prevalence of alternative medicine, and scientific study into the efficacy of this medicine should be followed. In the meantime, we suggest paying attention to possible harmful effects caused by some sorts of alternative medicine.

Animal testing was used traditionally in the cosmetics industry to confirm product safety, but has begun to be banned; alternative methods to replace animal experiments are either in development, or are being validated, worldwide. Research data related to test substances are critical for developing novel alternative tests. Moreover, safety information on cosmetic materials has neither been collected in a database nor shared among researchers. Therefore, it is imperative to build and share a database of safety information on toxicological mechanisms and pathways collected through in vivo, in vitro, and in silico methods. We developed the CAMSEC database (named after the research team; the Consortium of Alternative Methods for Safety Evaluation of Cosmetics) to fulfill this purpose. On the same website, our aim is to provide updates on current alternative research methods in Korea. The database will not be used directly to conduct safety evaluations, but researchers or regulatory individuals can use it to facilitate their work in formulating safety evaluations for cosmetic materials. We hope this database will help establish new alternative research methods to conduct efficient safety evaluations of cosmetic materials.

A commercial propolis was investigated in terms of its antioxidant, antimicrobial, and antiproliferative activities. The contents of total phenol and flavonoid of propolis were 8.3 and 6.6 mg, respectively. The reducing power of the propolis increased with concentration increasing. 1,1-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity was shown at 82.70% in 1,000 ${\mu}g/mL$ of the propolis. 2,2'-Azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging effect of antioxidant activity on the propolis was 35.64 g/sample. The propolis showed high antimicrobial activity against Bacillus cereus at all concentration of propolis. All of the cancer cell lines have 53-73% as effective growth inhibition. These results showed that the commercial propolis has potential antioxidant, antimicrobial, and cancer cell proliferative inhibition activities thus, propolis can be applied to the functional food, pharmaceutical, and cosmetic industry.

This study evaluated the quality characteristics of jelly prepared with different levels (0%, 5%, 10%, 15%, 20%, and 25%) of wild carrot (WC, Daucus carota L.) juice as a care food for the elderly. The lightness, redness, yellowness, and delta (${\Delta}$) values of the jelly (Control, WCJ5, WCJ10, WCJ15, WCJ20, and WCJ25) decreased with increasing amounts of wild carrot juice added. The mechanical properties, such as hardness, springiness, chewiness, and gumminess, of the jelly were decreased with increasing amounts of wild carrot juice added. The total polyphenol and total flavonoid contents of the jelly increased with increasing amounts of wild carrot juice added. The DPPH radical scavenging activity ($IC_{50}$) also increased with increasing amounts of wild carrot juice added. The ${\alpha}$-glucosidase inhibitory effects of wild carrot (WC) and WCJ25 were 71% and 54.4%, respectively, compared to the positive control (acarbose). The lipase inhibitory effects of WC and WCJ25 were 44.2% and 14.4%, respectively, compared to the positive control group (orlistat). On the other hand, the sensory evaluation score was the best at WCJ20, which contained 20% wild carrot juice. In conclusion, WCJ20 or WCJ25 is expected to be a care food for the elderly with respect to texture as well as the antioxidant and enzymatic activity (${\alpha}$-glucosidase inhibitory and lipase inhibitory activities).

The socio-cultural and economic changes following the Fourth Revolution are driving the growth of the food tech industry. Korea's food tech industry is still focused on delivery apps and the smart farms, robot market including artificial intelligence are in its infancy. In the United States, alternative meat companies are already included in unicorn companies, while Korea, the fourth largest importer of beef, lacks alternative meat development. France, Europe's largest agricultural country, is focusing on Agtech. China has developed the Internet and online e-commerce market with the world's number one population. Korea also needs to change regulations that focus on the past industry and various food tech industries should be developed through political and business-driven research and investment.

This study was investigated the optimal time that enhanced the functional activities of mung beans for use of functional food resources. Mung beans were roasted according three levels of roasting time levels (10, 20 and 30 minutes) at $110^{\circ}C$ and then the physicochemical compositions were determined. The reducing sugar content was decreased with the increased roasting time. Moisture was decreased with increased roasting time, whereas, crude fat, crude ash, crude protein and carbohydrate were increased with prolonged roasting time. The highest contents of total phenol and flavonoid were shown at a roasting condition $110^{\circ}C$ for 30 minutes. The highest inhibitory activities of DPPH radical, ABTS radical and xanthine oxidase was the best at the condition of $110^{\circ}C$ for 30 min. From these results optimal roasting time of mung beans were 30 minutes for use of functional food resources.

Development of alternative testing methods for the replacement of hazardous reagents with less hazardous ones is strongly enforced because exposure of human and environment to hazardous reagents are restricted and hazardous reagents are gradually prohibited from using in various testing methods. Thus, in this study, we developed 8 monographs from the Korean Pharmaceutical Codex by substituting the use of the hazardous reagents including ICH class 1 such as benzene, chloroform and dioxane to the use of less toxic ones like ICH class 2 or 3 reagents. We also improved their qualification and quantification performance. Among 8 monographs, the 6 newly developed TLC methods for the identification of nifedipine, oxolamine citrate, ketoprofen lysinate, chlorquinaldol, retinol acetate, and riboflavin showed a clear spot of corresponding material without any interference in spite of the replacement with ICH class 2 or 3 reagents. For the quantification of domperidone and trimebutine, HPLC methods were developed for the substitution of UV/VIS spectrometry and titrimetry, respectively. These HPLC methods were validated for the linearity, recovery, reproducibility, and inter-laboratory variations. In conclusion, the newly developed methods could be expected to become valuable tools for revising the Korean Pharmaceutical Codex.

The concerns over obesity and obesity-related health problems are increasing as many consumers relate these health problems with sugar. The demand for sugar reduction is also rising and regulatory movement by governments including Korea is driven to reflect such demand. For the past decades, there have been diverse development and marketing of various sweeteners to substitute sucrose and high fructose corn syrup. Low caloric alternative sweeteners can be divided into high intensity sweeteners that have greater sweetness potency compared to sucrose, and low intensity sweeteners such as polyols, oligosaccharides and rare sugars that have less sweetness potency. This paper discusses representative low caloric alternative sweeteners, their market and trend.

This research was carried out to find herbal preservatives for Makgeolli, as Makgeolli loses its commercial value due to overproduced acidic materials. When Makgeolli was kept at $25^{\circ}C$ to find the changes in acidity, total microbial cell number, yeast cell number, and bacterial species variety, a sudden increase of acidity as well as the disappearance of yeast cells occurred at day 6, and Makgeolli was changed to complete off-flavor. Acetobacter pasteurianus is the main acidifier in Makgeolli and shows a synergy effect in acid formation when cultured in combination with Lactobacillus casei. Among 12 herbs, the ethanol extract of Sutellaria baicalensis showed antimicrobial activity against A. pasteurianus, whereas the ethanol extract of Coptidis rhizoma showed antimicrobial activity against L. casei. Makgeolli added with Sutellaria baicalensis extracts demonstrated a lower acidity than that with Coptidis rhizoma extracts, which indicates that the inhibition of an acetic acid former is more important than that of a lactic acid former in Makgeolli preservation. Sutellaria baicalensis extracts prolonged the shelf life of Makgeolli by 1~2 weeks at a minimal inhibitory concentration ($0.63mg/m{\ell}$) during storage at $10^{\circ}C$.
