  • "Egreen" rye (Secale cereale L.) was developed by National Institute of Crop Science (NICS), RDA. It was released in 2007 because of its excellent earliness and yield potential. Crossing was made by an open pollination with 10 rye lines in 1995. Many lines from the open pollinated population were handled in a mass selection program in subsequent generations. Among them the line 'SR95POP-S1-116-1-1-2'was selected for earliness and promising agronomic appearance and placed in yield trial for two years from 2003 to 2004. In 2005, it was designated "Homil 34" and subjected to regional yield trials. Over 3 years, "Egreen" averaged 8.34 MT ha-1 of forage yield (based on dry matter) harvested at the heading date of check variety "Olhomil", which was superior to other varieties such as "Olhomil" and "Koolgrazer" with an increase of 8% and 10%, respectively. Heading date of "Egreen" was April 22, 3 days earlier than that of "Olhomil". It would be recommended as a winter crop forforage and green manure before planting either maize or rice in Korea.

  • Background: This study was designed to evaluate the clinical safety of Bee Venom (BV) pharmacopuncture at craniofacial acupuncture points. Methods: This was a retrospective study of 108 patients diagnosed with peripheral facial paralysis, trigeminal neuralgia, or facial spasm who were admitted to Kyung Hee University Korean Medicine Hospital at Gangdong, from April 1st, 2017 to August 30th, 2017. Patients were allocated into either, Group 1 (the non-allergy group of patients who did not have an allergic reaction to BV) or Group 2, the group who had allergic reactions to BV. To evaluate the clinical safety of BV pharmacopuncture after each treatment, several criteria were used to measure any side effects: outcome, Common Terminology Criteria for Adverse Events scale, Mueller HL scale, treatment decision after adverse reaction, causality, measures performed for patients with adverse reactions, and efficacy assessment. Results: BV pharmacopuncture delivered in 0.1-0.2 mL at a concentration of 1:30,000 at the craniofacial acupuncture points, showed no statistically significant differences in baseline characteristics between non-allergy Group 1 and allergy Group 2. Amongst the 108 patients, 11 reported side effects after BV pharmacopuncture treatment. These adverse events included rash (n = 7), pruritus (n = 5), swelling (n = 1), vesicles (n = 1), erythema (n = 1), and hives (n = 1). All side effects resolved without sequelae. Conclusion: In this study, BV pharmacopuncture delivered at low doses at the craniofacial acupuncture points, resulted in 10% of patients experiencing non serious side effects suggesting that BV pharmacopuncture was clinically well tolerated.

  • A new sesame variety 'Yunheuk' was developed from Yeongnam Agricultural Research Institute in 2007. A cross was made by 'Yoosung' with weak disease resistance and 'Kunheuk' with high yield capacity & quality, followed by pedigree selection, yield test and regional yield trial (RYT) by the sesame breeding team at the National Institute of Crop Science and Yeongnam Agricultural Research Institute up to 2007. The variety showed higher lodging resistance and more dark seed coloring rather than that of check variety 'Yangheuk'. Average stem length and the number of capsules per plant is 118 cm, 79 cm respectively. Its 1,000 grains weight is about 2.67 g indicating 0.10 g lower than that of 'Yangheuk', and its oil content is about 46.4%. 'Yunheuk' also contains total 2.59 mg/g of such lignans as sesamin and sesamolin. And its dark color density ($L^*$ Value) of seed coat is 22.43 which was about 10% lower than that of check variety. The average yield of 'Yunheuk' was 99.9 kg per 10a at the national-wide regional performance.

  • The size of the global game market, including Korea, is gradually expanding, there are about 80,000 people in the game industry in Korea, and it has maintained a steady increase. As the domestic game has become more influential, games have become a means of helping people to communicate with each other in everyday life. Despite these changes, There is a lack of positive perspectives such as game use and interpersonal interactivity or communication enhancement. Therefore, this study analyzed the correlation of psychological and environmental factors of adolescents, game leadership, and social capital in order to understand the positive effects of games. As a result of research, psychological factors such as social motivation, game efficacy, and game norms have a statistically significant effect on game leadership. Parental supervision has a negative effect on game leadership and a statistically influenced positive effect on social capital. Overprotective parenting has a negative effect on both game leadership and social capital. Finally, game leadership has a statistically influenced positive effect on social capital. This paper is meaningful in that the research on the positive aspect of the game was conducted for the adolescent.

  • Background: Lumbar herniated intervertebral disc (LHIVD) is a frequently presented condition/disease in Korean medical institutions. In this study, the economics of thread embedding acupuncture (TEA) was evaluated in a randomized controlled trial comparing TEA with sham TEA (STEA). Methods: This economic evaluation was analyzed from a limited social perspective, and the per-protocol set was from a basic analysis perspective. The cost-effectiveness analysis was based on the change in visual analog scale score, and the cost-utility analysis was based on the quality-adjusted life years. The final results were expressed as the average cost-effectiveness ratio and incremental cost-effectiveness ratio, and furthermore sensitivity analysis was performed to confirm the robustness of the results observed. Results: The cost-effectiveness analysis showed that TEA was 9,908 won lower than STEA, while the decrease in 100 mm visual analog scale score was 8.5 mm greater in the TEA group compared with the STEA group (p > 0.05). The cost-utility analysis showed that TEA was 9,908 won lower than STEA, while the quality-adjusted life years of TEA was 0.0026 years higher than STEA (p > 0.05). These results were robust in the sensitivity analysis, but were not statistically significant. Conclusion: In treating LHIVD, TEA appeared to have cost-effectiveness and cost-utility compared with STEA. However, there were no significant differences between the groups in terms of cost, effectiveness, and utility indicators. Therefore, results must be interpreted prudently; this study was the 1st to conduct an economic evaluation of TEA for LHIVD.

  • This study evaluated the effects of acidulant treatment on the quality and storage period of Topokkidduck. Two samples of Topokkidduck were prepared, one soaked in 10% acidulant (10SAT) and the other without soaking in the acidulant (NSAT). During the storage period, the two samples were tested for presence of microorganisms (aerobic bacteria, E.coli, and mold) and physicochemical properties (color value, texture profile analysis (TPA)). The 10SAT could be stored for 49 days without detection of E.coli and a mold level of 1.0 log CFU/g. NSAT could be stored for only 21 days. NSAT had an aerobic count of 2.27 log CFU/g as early as 7 days, and E.coli was detected at 21 days at a level of 4.15 log CFU/g. The presence of E.coli is not permitted according to the Ministry of Food and Drug Safety (MFDS). The hardness of the 10SAT increased during the storage period but to a much lesser extent compared to the NSAT. Thus the preparation of Topokkidduck by soaking in the acidulant controlled microbial growth for up to 49 days which is a much longer period compared to the control. Also, Topokkidduck soaked in the acidulant had a softer texture than the control during the storage period.

  • In this study, we investigated inhibitory effect of Tripeptide against particulate matter (PM)-induced damage in human keratinocytes. PM-induced cell death was inhibited by Tripeptide and the activity of aryl hydrocarbon receptor (AhR) also inhibited by Tripeptide resulting in reduced expression of its downstream targets, cytochrome P450 family 1 subfamily A member 1 (CYP1A1) and cyclooxygenase-2 (COX-2), which are responsible for toxic metabolites production and inflammation. Furthermore, PM-induced expressions of pro-inflammatory cytokines, matrix metalloproteinase-1 (MMP-1) and apoptosis-related factors were decreased by anti-oxidant activity of Tripeptide. From these results, it has been shown that the Tripeptide has protective effect against PM-induced skin damage not only through the inhibiting of keratinocyte death but also through the inhibiting the secretion of several damage-inducing factors to adjacent skin tissue. And the results suggested that Tripeptide with anti-pollution effect could be applied as a new functional cosmetic material.

  • This study was conducted to provide basic data to establish health promotion and chronic disease management education programs and educational plans for well-aging by investigating the educational needs for health promotion and chronic disease management by life cycle. This is a descriptive correlation research study, and collected and analyzed through a structured questionnaire targeting 330 adults over 19 years of age registered at Gallup Korea. The results of the study were perceived health status 3.11 points (SD=.72), health promotion behavior 2.27 points (SD=.47), and health-related quality of life 0.92 points (SD=.10). Health-related quality of life was found to have a positive correlation with perceived health status (r=.472, p<.001) and health promotion behavior (r=.122, p<.026). The priority of educational needs and contents for health promotion and chronic disease management was the highest in chronic disease management. There was a significant difference according to the life cycle (p=0.001), and it was found that the mature stage was more likely to be aware of the level of knowledge, the need for education, and the willingness to participate in education compared to the youth. Through the results of this study, it is necessary to develop a comprehensive customized program that is subdivided according to the life cycle when developing health promotion and chronic disease management education programs for well-aging.

  • Some flowers have high sensual appealability due to their unique shapes, colors, smells, and tastes. Such edible flowers receive social attention as a noble ingredient of functional teas. In this study, methanol extracts of 23 commercial flower teas (CFTs) were prepared, and their color differences were compared. No tar color pigments were detected in the 23 CFT. The average content of total polyphenol of the 23 CFTs was 80.2±50.92 mg/g and the extracts of jin-dal-rae (Rhododendron mucronulatum Turcz), mae-hwa (Prunus mume), mae-mil (Fagopyrum esculentum), mok-ryun (Magnolia kobus), and sal-gu (Prunus armeniaca var. ansu Maxim) flowers showed total polyphenol contents greater than 150 mg/g. The average content of total sugar of the 23 CFTs was 187.4±166.5 mg/g and the extracts of chamomile (Chamaemelum nobile), kuk-hwa (Chrysanthemum morifolium), dong-baek (Camellia japonica L.), and won-chu-ri (Hemerocallis fulva) flowers showed total sugar contents greater than 400 mg/g. Among the 23 CFTs, the extract of jang-mi (Rosa hybrida hortorum) flower has prominent anti-thrombosis activity, and the extracts of dal-ma-ji (Oenothera lamarckiana), dong-baek, hibiscus (Hibiscus syriacus), and mae-mil flowers showed strong inhibitions against thrombin and blood coagulation factors. Also, the extracts of jang-mi, kum-jan-hwa (Tagetes erecta L.), mae-mil, mok-ryun dong-baek, and jin-dal-rae flower showed strong radical scavenging activities against DPPH, ABTS, and nitrite and reducing power. Our results suggest that the flowers of jang-mi, mae-mil, and dong-baek can be developed as promising anti-thrombosis treatments.
