Consumers prefer high-quality organic agricultural products, but most organic farmers use conventional seeds. Therefore, it is necessary to establish an organic seed production technology for organic vegetable cultivation which will meet international organic standards. In this study, the effects of low temperature treatment and seedling size on flower bud differentiation and planting were investigated for the production of indigenous organic root vegetables seeds, radish, turnip, and beet. Radishes were bolted in large seedlings which were cold treated for 4 weeks after 16 days of transplantation. Turnips were bolted in small seedlings which were cold treated for 2 or 4 weeks after 28 days of transplantation. Beets were bolted in small seedlings which were cold treated for 4 weeks, 23 days after planting. It was found that small size radish seedlings were not affected by the 4 weeks low-temperature treatment, but for turnips and beets, smaller seedlings rapidly bolted as compared to larger seedlings which were treated for 2 or 4 weeks. Based on these results, it could be inferred that it is possible to increase the seed production yield of radish, turnip, and beet as well as predicting the planting time. These findings could be used as basic data to determine the appropriate seedling size and cold-treatment time.

Pleurotus species are the most consumed and cultivated mushrooms in Korea. Although oyster mushrooms (P. ostreatus) can be cultivated automatically, their storability is slightly lower than that of king oyster mushrooms (P. eryngii) and winter mushrooms (Flammulina velutipes); therefore, the export proportion of oyster mushrooms is very low. Since Korean mushrooms are highly preferred across Southeast Asian, the export of oyster mushrooms in the form of complete substrates is expected to be more promising than that of fresh mushroom. Here, 1 and 2.5 kg complete substrates of P. ostreatus ‘Soltari’ and P. sajor-caju ‘Sambok’ were prepared and stored at different temperature from 0 to 15°C for 10 days. Thereafter, the formation of fruiting bodies was induced. Since the 2.5 kg complete substrates required 70 days of incubation, their mycelia were at an advanced age and their fruiting bodies did not grown normally. When 70%-incubated complete substrates were stored at 5–10°C, the growth was faster and more uniform and stable fruiting bodies were formed. Export test of complete substrates to Vietnam using distribution containers set at 0°C and 15°C revealed that the growth period was shortened by 1–2 days when the distribution containers were set at 15°C and the yield of ‘Soltari’ increased by approximately 10%. In addition, even though the yield of ‘Sambok’ was similar between treatments at 0°C and 15°C, the quality of fruiting bodies from 15°C-distributed complete substrates was much better than that of those from 0°C-distributed substrates.

Owing to its excellent nutritional value, eggs are among the most important components of the human diet. Gender and environmental factors, such as feed composition, may alter the nutritional profile and quality of eggs. Feed additives have recently been used to enhance the health and productivity of hens, which has resulted in the production of higher-quality eggs. The fungus Cordyceps militaris, a well-established source of traditional medicines, contains potential bioactive metabolites, which prompted us to examine the effects of C. militaris-supplemented diets on the quality of hens’ eggs. The hens of two species (Gallus gallus domesticus and Araucana) were fed with one of three different diets: a control diet and diets supplemented with 2% or 5% of C. militaris. Egg quality was determined by measuring the Haugh Unit, yolk color, and shell thickness. In addition, egg and shell densities together with the ratio of yolk to albumen were calculated. Eggshell thickness and yolk color were both enhanced by the addition of C. militaris, whereas Haugh Unit values were somewhat reduced. Egg size, eggshell weight, and yolk and albumen production were all enhanced by C. militaris supplementation. Notably, in hens fed the 2% C. militaris-supplemented diet, enhancement was more evident in the yolk than in the albumen. The overall quality of the egg yolk was enhanced when 2% C. militaris was added to the hens' diet, which led to increases in both yolk color and quantity. Eggshell thickness and weight were also higher among eggs laid by hens fed the supplemented diets. Although these effects differed depending on the chicken species, we established that, in general, C. militaris contributes to improving egg quality.

Flammulina velutipes, known as winter mushroom in the family of Physalacriaceae, is the main edible and export mushroom with the third highest production after oyster and king oyster mushroom in Korea. However, as normal consumers regard F. velutipes as a simple subsidiary material, there is a limitation to increasing mushroom demand. In order to overcome the consumption limit and increase the differentiation of new varieties, it is necessary to breed varieties with enhanced functionality in consideration of consumer preferences. Therefore, the study was performed to analyze nutrient components and several useful functional substances with 26 genetic resources of F. velutipes. Analyses of inorganic compound(Ca, K, Mg) and 15 amino acids revealed that Strain 4148 had the highest content among the 26 strains. Beta-glucan, which increases immune activity and polyphenol, which exert antioxidant effects were higher in non-white strains than in white strains with a small number of exceptions. Among the five fatty acids, linoleic acid(an omega-6 fatty acid) and α-linolenic acid(an omega-3 fatty acid), were detected in six mushroom strains. α-linolenic acid, which was not found in five major mushrooms including oyster mushrooms, was identified in F. velutipes. The results of HPLC analysis showed that ‘Auram’ (Strain 4232) and ‘Baekseung’(Strain 4230) had the highest content of the stabilizing neurotransmitter GABA(15.38 μg/ml and 20.56 μg/ml, respectively) among non-white and white strains, respectively. Our findings provide useful information for breeding F. velutipes to obtain strains with enhanced functionality.

This article examines the variations found in the use of ‘eung’ and ‘eo’ in TV dramas and their scripts. Five series of TV drama televised during the 2010s were used as the data for this study, and 3,202 tokens of {eung} and {eo} were collected from the data. Statistical analyses were conducted using Goldvarb X and LVS (Language Variation Suite). Nine variants of {eung} and six variants of {eo} were observed in the data. Regression analyses showed that ‘discourse function’ of {eung} and {eo} was the primary constraint influencing the variation examined. Age was analyzed as another statistically significant factor: Older people used {eung} variants more often than younger people. This result may be taken to indicate either age grading or linguistic change in progress; further research based on careful methodology is in order for its accurate interpretation.

The physicochemical properties of the emulsions prepared with four different proteins (pea protein isolate, whey protein isolate, soy protein concentrate, and soy protein isolate) were characterized in terms of particle size, rheological property, and freeze-thaw stability, while the feasibility of the protein-stabilized emulsions as a fat replacer was evaluated. Confocal laser scanning microscopic analysis showed that O/W emulsions were successfully prepared with all the proteins; however, the smallest particle size and excellent syneresis were observed in the WPI-stabilized emulsions. The use of WPI-stabilized emulsions as an alternative for shortening up to 50% level did not lead to differences in the muffin batters’ specific gravity and viscoelastic properties. After baking, the substitution of shortening with the WPI emulsions at up to 50% by weight did not significantly affect the muffins’ specific volume and texture characteristics.

지역의 혁신역량은 지속 가능한 지역경제의 주요한 성장의 원천으로 받아들여지고 있으며 이에 관한 많은 연구가 보고되었다. 최근에는 지역혁신체제의 정책적 수행과정에서 지역의 특성을 반영해야 한다는 스마트 특성화 전략이 제안되었으나, 실증 연구는 제한적인 결과를 제시하는 데 그치고 있다. 이에 본 연구는 스마트 특성화를 기존의 지역혁신 연구의 보완 전략으로 접근하여 한계점을 극복하고자 하였다. 이를 위해 스마트 특성화를 지역혁신체제의 대체 전략이 아닌 지역혁신 역량의 제도 요소로 보고, 지역혁신역량과 지역경제 간 관계를 분석하여 스마트 특성화가 지 역경제에 미치는 영향을 파악하였다. 국내 16개 시·도에 대해 2009-2018년의 10개년으로 구 성한 패널 모형을 통해 연구를 수행하였으며, 적합한 패널 모형을 탐색하는 과정을 통해 최 종적으로 FGLS모형을 활용하였다. 연구 결과 산업의 연관 다양성과 비연관 다양성으로 구성된 스마트 특성화는 지역경제에 긍정적인 영향을 미치는 것으로 나타났다. 또한 기반 요소, 촉진 요소로 나누어 측정한 다른 지역혁신역량 역시 지역경제에 긍정적인 영향을 미쳐 기존 지역혁신과 지역경제 간 긍정적인 연구 결과를 확인하였다. 본 연구는 국내 연구가 부족한 스마트 특성화를 지역혁신역량의 제도적 요소로 보고 지역별 산업 연관 다양성과 비연관 다양성을 통해 이를 측정하였다는 데 의의가 있다.

The purpose of this study is to analyze the body type characteristics of tall adult men aged 20 to 69 years to present base material on body dimensions for men’s clothing companies. The research method comprised statistical analysis of 3D measurements after selecting items from the 8th Korean human body size survey related to the torso body types of 495 adult men who were at least 178cm tall. As a result, six factors were extracted, and the total explanatory variable of the entire factor was shown to be 80.499%. As a result of cluster analysis using this as an independent variable, three types were derived: Type 1, “a normal body type with an oval cross-sectional shape” (37.6%), with a larger vertical size and an oval chest cross-sectional shape compared to other types; Type 2: a “cylindrical thick body shape” (31.1%), which is the first stage of BMI obesity, with narrow shoulders and a cylindrical shape with a round cross-section; Type 3, “a body shape with broad shoulders and developed chest parts” (31.3%), with a horizontal size similar to Type 2 above the waist, but similar to Type 1 below. The results of this study are expected to be used as a basis for a clothing dimension system and clothing development for tall men reflecting the characteristics of the torso.

In this study, we compared the microbial reduction effects of drying, hot water, and microwave sterilization in scourers and dishcloths to suggest a most suitable sterilization method. Three scourer types (silver, copper, and mesh) were used, and three dishcloth types (silver, bamboo, and cotton) were used. Drying time dependent reduction in Escherichia coli was high in silver and copper scourers, but minimal bacterial reduction was obtained against Bacillus cereus in all scourers and dishcloths. In scourers, E. coli was not detected after ≥30 s of hot water sterilization at 77oC, and B. cereus was not detected after ≥60 s of hot water sterilization at 100oC. In dishcloths, E. coli was not detected after hot water sterilization at 77oC for ≥30 s, but B. cereus was detected after hot water sterilization at 100oC for ≥60 s. In scourers, E. coli was not detected after microwave sterilization at 700 W for 3 min, but B. cereus was detected. In dishcloths, E. coli was not detected after microwave sterilization with 700 W for ≥1 min, but B. cereus was detected in the cotton dishcloth even after sterilization for 3 min. In conclusion, the use of antimicrobial scourers (silver and copper) and dishcloths (silver and bamboo) are not sufficient to reduce the microbial contamination. The guideline provided by the Ministry of Food and Drug Safety suggesting dishcloth sterilization via hot water at 100oC for 30 s was also found to be insufficient. Based on our research, we suggest that the most effective methods of microbial management are submerging scourers in hot water at 100oC for ≥1 min, and sterilizing dishcloths for ≥3 min using a 700 W microwave.

본고는 남한지역의 생활 유구와 분묘에서 출토된 유경식 석검의 속성을 검토해 형식분류하고 이를 통해 지역성 및 전개 양상, 석검의 성격과 기능 추정을 목적으로 하였다. 남한지역을 다섯 개 권역으 로 세분하고, 계측형과 명목형 속성을 검토한 결과, 기존 연구에서 주목했던 경부 길이는 검신부 길이 와 무관하게 2~5.4cm 범위에서 제작되어, 본고에서는 형식분류 기준을 경부 길이가 아닌 경부 형태, 전체 길이, 최대폭 위치로 설정해 11개 형식으로 구분하였다. 방사성탄소연대 측정치와 공반유물을 종합해 지역·형식별 시간성을 검토한 결과 전 지역에서 전기 후반부터 유경식 석검이 등장했고, ⅠA 식 석검이 선호되었음을 확인하였다. 중기에는 석검의 크기와 경부 형태의 다양성이 확인되었고, 생 활 유구와 더불어 분묘에도 부장되기 시작하였다. 그러나 전기 물질문화 전통이 지속되었던 중부, 강 원, 영남 동해안 권역에서는 여전히 생활 유구에서만 사용되었고 분묘 부장 사례는 송국리 문화가 확 산된 권역에서 확인되어, 유경식 석검의 분묘 부장은 송국리 유형의 확산 결과로 이해하였다. 한편 중 부지역은 각형토기 문화권과 형태적 유사성이 높은 Ⅳ형식 석검, 전기부터 9개의 형식이 등장했으나 소멸 양상이 이르게 확인되는 점, 물질문화의 이동 방향을 고려했을 때 남한지역에서 유경식 석검의 확산은 중부지역을 통해 이루어진 것으로 이해하였다.
