Nutrition education should be an important component of ongoing health promotion for older adults and their caregivers. This is because prevention through sound nutrition and food hygiene practices and regular excercise is the most cost-effective way to reduce risks for and deal with their major health problems. nutritions education services should effectively promote optimum intake and successful self-care. Unfortunately, however relative to other vulnerable groups, nutrition education for older adults has not been systematically developed or evaluated. Usually oder adults care a lot about their health, so this should be a relatively easy group to teach - but their increasing numbers, longevity and great diversity with respect to health, physical, and economic status and educational level present challenges. Some older adults may not perceive they would benefit from nutrition education, so interesting and motivating them is a challenge. The food and nutrition knowledge of older people has been acquired through a lifetime of experience. For most older adults in the Asian region, their sources are restricted by their restricted education, so that their major sources of information have been informal sources, such as television, radio, friends, family, and perhaps newspapers and magazines if they are literature. Nonetheless, dietary advice for older people should build on their existing knowledge and ingrained values. It should provide information useful in daily food selection, and focus on food, not nutrients - the same foods and groups considered appropriate for younger people, with consistent messages as given throughout the population. Attention must also be paid to discovering learning styles in older people. When we teach in schools, the young students are a captive audience resigned to their learning role. Learning by an older adult, however, reflects an effort to meet his or her perceived needs. Therefore, nutrition education should be a positive experience in a non-threatening environment, relaxed and non-competitive, and perhaps even social environment. The messages also need to be practical and achievable. A needs assessment is essential, because our ability to provide the most effective nutrition education will depend on our success in matching the needs, both perceived and unperceived. of this vulnerable group. Therefore, go to the potential older learners to assess their interest and preferences. Nutrition education activities for older adults are widespread, but few have been evaluated. Evaluation is therefore also recommended, particularly when new methods are used. Tips from other countries for giving successful nutrition education will be given, including some examples of applications as attempted in Hong Kong. Research needs will also be described. In conclusion, successful nutrition education for older adults depends on positive needs-based messages. This is may be hard to do, as few good examples are available to illustrate these principles.

High-quality and high-phytonutrient watermelon fruits have strong market opportunities besides their health related benefits. Hence, investigating quality and nutritional related traits of watermelon genetic resources could provide important baseline data in breeding for increased lycopene content thereby increasing the marketability of watermelon. To this end, we have examined some fruit morphological traits and lycopene content of 105 genetic resources. Seeds, originally obtained from 22+ countries, were obtained from the National Agrobiodiversity Center, Jeonju, South Korea, grown in an experimental field and harvested at a fully mature stage. The size of pistil scar (SPS), the width of stripes (WS), weight of fruit (WF), length of fruit (LF), width of fruit (WIF), the thickness of pericarp (TP), soluble solids content (SSC), fruit shape in longitudinal section, ground color of skin, the intensity of the green color of skin, fruit shape at the apical part, grooving distribution, conspicuousness of stripes, and main color of the flesh were recorded on the field and inside laboratory and the lycopene was measured using spectrophotometric and HPLC methods. Watermelon fruits have shown a diverse morphological characters. Red and pink fleshed fruits dominated in the entire collections. Fruits with higher thickness of rind were found to exhibit less soluble solid content (SSC). Korean origin fruits were characterized by intermediate SSC while the United States of America (USA), Russia (RUS), Tajikistan (TJK), Turkmenistan (TKM), Taiwan (TWN), and Uruguay (URY) originated fruits had the highest SSC. The lycopene content varied between 41.37 and 182.82 ㎍/g, 2.81 and 163.72 ㎍/g, and 3.54 and 255.47 ㎍/g using HPLC, UV-Vis spectrophotometer, and microplate reader spectrophotometer, respectively. Red- and pink-fleshed fruits had the highest levels of lycopene content compared to the yellow- and orange-fleshed. Lycopene content had a significant positive correlation with SSC, however, no correlations were detected between lycopene and other quantitative fruit morphological characters. Our study demonstrated high diversity exists in fruit morphological traits and lycopene content of the germplasm collections which provide beneficial baseline data for a future breeding program and utilization of watermelon germplasm collections in gene banks for the maintenance and improvement of the current levels of production, marketability, and health-related benefit of watermelon fruits.

The purpose of this study was to find efficient and customized tools for delivering the benefit of health functional foods (HFFs). Delivery tools which could influence the impact of advertising were images, explanations of ingredients, diagrams of health benefit, patents, and comments from authority. Six advertisements were developed using these tools: "A": relevant image + explanation of ingredients + scientific diagram of efficacy; "B": relevant image + explanation of ingredients; "C": relevant image; "D": irrelevant image; "E": irrelevant image + explanation of ingredient + patent; "F": irrelevant image + explanation of ingredient + comments from authority. To analyze the consumer perceptions on HFFs and advertisement effects, 300 respondents were requested to answer a questionnaire comprising of the following questions: 5 questions of attitudes (necessity of HFFs, trust in HFFs, gathering information, watching advertisements and trust in advertisement claims) and 6 questions on the 6 developed advertisements (attention, understanding, sufficiency of information, sympathy, trust, and purchase). Scoring was done as per the 5 Likert scale. There was a higher proportion of females and the elderly, as compared to males and youngsters. The overall consumer attitudes were positive. Explanation of ingredients, scientific diagram of health benefit, patents and expert comments were helpful factors in increasing the advertisement evaluation by consumer, but the images were not. Advertisement evaluation of consumer did not differ with gender and age. However, differences were observed between some of the consumer attitudes (necessity of HFFs, trust in HFFs, gathering information and trust in advertisements claim) and advertisement evaluations (attention, understanding, sympathy and purchase). Our results indicate that for consumers utilizing the HFFs, advertisements with concrete tools such as diagrams, patent, and expert comments are more helpful. However, for consumers who do not have interest in HFFs, the scientific information was irrelevant. We believe that to maximize the effect of health information in advertisements, consumers should be segmented, and customized tools for each segment needs to be developed.

Gu-Chang is a disorder characterized by recurring ulcers confined to the oral mucosa. Despite much clinical and research attention, the causes remain poorly understood. In this paper, we will compare Gu-Chang with Recurrent Aphthous Stomatitis(RAS) in order to know what is the similiarity between Gu-Chang and RAS. So we will arrange various oriental and western medical literatures which are important. As a result of arrangement of the causes, symptoms and therapys of Gu-Chang, we can conclude through the studies as follows. 1. The etiologies of Gu-chang are following. In the Sthenia syndrome, there are evil heat of external factor, heat of heart and spleen, insomnia, heat of upper warmer, stress and diet, heat of lung and heart, excessive heat of upper warmer, inappropriate food intake, heat conveyance of organ, heat of stomach merdian, moistured heat of spleen and stomach and stasis of liver energy. In the Asthenia syndrome, there are deficiency of stomach energy, deficiency of upper warmer leading to heat, deficiency of middle warmer leading to cold, deficiency of lower warmer leading to heat, deficiency of middle energy, deficiency of blood, decreased fire and deficiency of soil, yin fire of lower warmer, deficiency of heart yin, deficiency of spleen yin and deficiency of qi and blood. 2. In western medicine the causes of RAS is presumed as local, microbial, systemic, nutritional, genetic, immunologic factors. 3. Once Gu-chang is compared with RAS, in the deficiency of yin leading to hyperactivity of fire, deficiency of yin leading to floating of fire and stasis of liver energy, recurring of Gu-chang is similar to RAS. Although recurring of Gu-chang due to tripple warmer of excessive fire has no recurrance, since there are the degree of Pain, site of lesion, dysphagia etc, it is similar to major RAS. It is may be believed that Sthenia Gu-chang is similar to major RAS, shape of recurring, site of lesion, degrree of Pain and white color of Asthenia Gu-chang are similar to minor RAS, but there is no similarity concerning herpes RAS in the literatures that describe the symptoms. 4. Generally, the treatment of Gu-chang is divided into Asthenia and Sthenia Syndrome. The method of cure to Sthenia syndrome is heat cleaning and purge fire, Asthenia syndrome is nourish yin to lower and adverse rising energy and strength the middle warmer and benefit vital energy. 5. Following is the medication for Sthenia syndrome. Heat of heart and spleen is Do Jok San, Yang Gyek San, Juk Yup Suk Go Tang, evil heat of external factor is Yang Gyek San Ga Gam, Stasis of liver energy is Chong Wi Fae Dok Yum, moistured heat of spleen and stomach is Chong Gi Sam Syep Tang. The medication for Asthenia Syndrome is following. Deficiency of upper warmer leading to heat is Bo Jung Ik Gi Tang, deficiency of middle warmer leading to cold is Bu Ja Lee Jung Tang, deficiency of lower warmer leading to heat is Yuk Mi Ji Hwang Tang, deficiency of yin leading to hyperactivity of fire is Ji Baek Ji Hwang Hwan, deficiency of yin leading to floating of fire is Lee Jung Tang Ga Bu Ja Medicine for external use were Yang Suk San, Boo Wyen San, Rok Po San, Yoo Hwa San ate. 6. In western medicine, there is no specific treatment for RAS, and management strategies depend on dinical presentation and symptoms and includes antibiotics, oral rinses, glucocorticoids, immunomodulatory drugs, vitamines, analgesics, laser and antiviral agents.

In order to evaluate suitability by processing for non-GM soybean cultivars such as Gaechuck#2, Jinyangkong and CJ#1 lacking lipoxygenase (LOX) and kunitz trypsin inhibitor (KTI) protein, physicochemical characteristics and antioxidant activity of Kanjang made from above soybean were compared to Kanjang made from a conventional cultivar (Taekwangkong). Proximate compositions of soybeans were similar for the 4 kinds cultivars. Total phenol and flavonoid contents were significantly higher in cultivars lacking LOX and KTI protein than the Taekwangkong. In Kanjang, contents of total and reducing sugar were higher in Taekwangkong Kanjang than Kanjang from made cultivars lacking LOX and KTI protein. Contents of total and amino type nitrogen were the highest in the Jinyangkong Kanjang. Mineral contents were higher in the Jinyangkong and CJ#1 Kanjangs, amino acid contents were higher in the Kanjang made from 3 cultivars lacking LOX and KTI protein than the Taekwangkong. Taste of the Jinyangkong Kanjang with higher sweety and savory was also found to be superior to that of others in overall acceptability evaluation. Total phenol and flavonoid contents in Kanjang were significantly higher in the Kanjang made from cultivars lacking LOX and KTI protein than the Taekwangkong. Radical scavenging activity of Kanjang was increased in the total phenol contents dependent on. Reducing power by ferric-reducing antioxidant potential (FRAP) was significantly higher the Kanjang made from Gaechuck#2 and CJ#1 than the Taekwangkong. $Fe^{2+}$ chelating activity was higher in Taekwangkong Kanjang than the other cultivars, but its activity was similar to Jinyangkong Kanjang. Therefore, higher nutritional composition, total phenol and flavonoids contents and antioxidant activity in the Kanjang made from soybean cultivars lacking LOX and KTI protein might be provide better benefit for manufacture of another their products.

The content of nutrients, proteins, and oils of crop seeds is affected by global climate change due to the increase in temperature. Information regarding the effects of increased temperature on soybean seed nutrition is limited despite its vital role in seed quality and food security. The objective of this study was to determine the effect of increasing temperature on seed nutrient, protein, and oil content in two soybean [Glycine max (L.) Merr] cultivars (Daewonkong and Pungsannamulkong during the reproductive period in a temperature-gradient chamber. Four temperature treatments, Ta (near ambient temperature), $Ta+1^{\circ}C$ (ambient temperature+$1^{\circ}C$), $Ta+2^{\circ}C$ (ambient temperature+$2^{\circ}C$), $Ta+3^{\circ}C$ (ambient temperature+$3^{\circ}C$), and $Ta+4^{\circ}C$ (ambient temperature+$4^{\circ}C$), were established by dividing the rows along the temperature gradient. At maturity, increased temperature did not significantly affect the concentration of P, K, Ca, and Mg. The protein and oil content was significantly correlated with temperature. At maturity, the protein content of DWK and PSNK was reduced at $Ta+4^{\circ}C$. The oil content was the highest at $Ta+4^{\circ}C$ in DWK, whereas it decreased in PSNK at $Ta+4^{\circ}C$. Consequently, the biochemical composition of soybean seeds changed with the increase in temperature. These results illustrate the effects of temperature on soybean seed nutrient, protein, and oil content, which can help improve soybean quality at different temperatures. Thus, the biochemical composition of crop seeds can be changed in accordance with nutritional requirements for the benefit of human health in the future.

Gastric cancer is one of the most common cancers in Korea and the world. Since 2004, this is the 4th gastric cancer guideline published in Korea which is the revised version of previous evidence-based approach in 2018. Current guideline is a collaborative work of the interdisciplinary working group including experts in the field of gastric surgery, gastroenterology, endoscopy, medical oncology, abdominal radiology, pathology, nuclear medicine, radiation oncology and guideline development methodology. Total of 33 key questions were updated or proposed after a collaborative review by the working group and 40 statements were developed according to the systematic review using the MEDLINE, Embase, Cochrane Library and KoreaMed database. The level of evidence and the grading of recommendations were categorized according to the Grading of Recommendations, Assessment, Development and Evaluation proposition. Evidence level, benefit, harm, and clinical applicability was considered as the significant factors for recommendation. The working group reviewed recommendations and discussed for consensus. In the earlier part, general consideration discusses screening, diagnosis and staging of endoscopy, pathology, radiology, and nuclear medicine. Flowchart is depicted with statements which is supported by meta-analysis and references. Since clinical trial and systematic review was not suitable for postoperative oncologic and nutritional follow-up, working group agreed to conduct a nationwide survey investigating the clinical practice of all tertiary or general hospitals in Korea. The purpose of this survey was to provide baseline information on follow up. Herein we present a multidisciplinary-evidence based gastric cancer guideline.
