경기도내 유통되는 식용 버섯류의 방사능 안전성을 확보하기 위해, 버섯 종류별, 원산지별 샘플을 수거하여 방사능 오염도를 분석하였다. 버섯류 10종(표고버섯, 느타리버섯, 새송이버섯, 양송이버섯, 팽이버섯, 상황버섯, 차가버섯, 목이버섯, 영지버섯, 송이버섯) 총 284건을 수거하여 방사능 검사를 수행하였다. 인공방사성물질인 131I, 134Cs 와 137Cs의 방사능 농도는 감마선 측정 장비로 분석하였다. 모든 버섯 샘플에서 131I과 134Cs은 MDA 값 이상에서 검출되지 않았다. 그러나 국내산 204건 중 총 6건(표고버섯 3건, 영지버섯 1건, 송이버섯 2건)에서 137Cs 이 0.21~2.58 Bq/kg 검출되었고, 수입산 80건 중 총 38건 (차가버섯 22건, 상황버섯 14건, 표고버섯 1건, 송이버섯 1건)에서 137Cs이 0.21~53.79 Bq//kg 검출되었다. 그리고 차가버섯을 이용한 가공품 10건에서는 건조 차가버섯에 비해 평균 2배 이상의 137Cs가 검출되었고, 최고 123.79 Bq/ kg이 확인되었다. 이와 같은 결과를 종합하여 볼 때, 식품 안전 확보를 위해 일부 수입 버섯류와 가공품에 대한 방사능검사 강화와 함께 지속적인 모니터링이 필요하다 하겠다.

Developments in the recent media era has made distortion possible in accordance with changes in the fashion industry as new clothing, technologies, and fusions have become available. Nevertheless, previous studies of specific types of clothing, and their classification for the purpose of research are lacking. Thus, this study examines the development of the Pomme de look and the form of modern variant that appears in fashion clothing and new technologies, and largely examines the clothing case to clean it up. The method employed is leading research that examines the transformation about the concept of the Pomme de look with regard to the fashion about the type of look in the 2000s and onwards. This is organized in accordance with the analytical and physical characteristics, and the esthetic aspects of the results are as follows. The conclusions reached as follows are based on this; first, the physical characteristic manner when based on previous looks, the two-dimensional deformation for making clothes, if there was a simple way, now has more dimensions. Clothes are made in a complex manner and variations emerge. Second, esthetic characteristics strive for beauty while also displaying the modified and more complex manners of clothing that are emerging. Third, the fusion clothing with machines effects to physical and psychological changes through the details about how the sensor is worn. The enemy, the appearance of distortion, and clothing are emerging. This is expected to grow further based on the rapid development of new technologies and the transformation of Pomme de look and design will appear in more varied ways to create a convergence.

We investigated to analyze the ecological changes of plants in the Wolyoung wetland conservation area from August 2014 to September 2015. The vascular plants investigated in the 2011 literature are 153 taxa(50 families, 110 genera, 136 species, 16 varieties, 1 form). Field survey in 2015 was 208 taxa(66 families, 145 genera, 182 species, 1 subspecies, 23 varieties, 2forms). In the 2015 survey, most vascular plants were composed of dicotyledons. Also, naturalized plants of vascular plants were investigated as 8 taxa(3.85%). Gramineae was the most abundant in 21 taxa, Rosaceae and Compositae were found in 15 taxa. In 2015, the number of vascular plant increased in 55 taxa, and the naturalization plant was increased in 5 taxa than 2011. The reason why number of vascular and naturalization plant increased is disturbance for increase of visitors, wetland succession, landization, etc. The Wolyoung wetland consists of four small wetlands. The vascular plants of Wolyoung wetland were investigated as follows: 1 wetland 152 taxa, 2 wetland 102 taxa, 3 wetland 89 taxa, and 4 wetland 99 taxa. Among the life forms of vascular plants, the Dormancy form showed a high distribution of G(Geophyte) in 2011 and a high distribution of H(Hemicryptophytes) in 2015. Among the Propagation form, Radicoid form showed the type of R5(taxa without lateral spreading) > R3(taxa with the smallest lateral spread rhizome) > R2,3 in both 2011 and 2015. Among the Propagation forms of vascular plants, the Disseminule form was investigated in order of D4(plants disseminated by gravity) > D1(plants disseminated by wind and water) > D2(plants disseminated by animals and human) in both 2011 and 2015. Growth form of vascular plants was surveyed in order of e(erect form) > t(crowding form) > ps(rosette-erect form) in both 2011 and 2015. Especially, the increase of crowding form(t) and branching form(b) reflects the characteristics of Gramineae and Cyperaceae that are major dominant Family of wetland vegetation, and gradually shows the typicality of wetland vegetation.

The aims of the present study were to estimate the possibility for toxicity test and compare acute toxicity of potassium dichromate in the larva stage of Neocaridina denticulata, Daphnia magna and the juvenile stage of Oryzias latipes. N. denticulate, a freshwater shrimp lives in Korea, is an indigenous species and considered to be useful for toxicity test. D. magna and O. latipes were recommended as a test species for the OECD test guideline. The 96 h-LC50 potassium dichromate value was 0.62 mg L-1 for the larva stage of N. denticulata and 168.44 mg L-1 for the juvenile stage of O. latipes. The 48 h-EC50 value was 1.27 mg L-1 for the D. magna. The study was confirmed higher sensitivity of the larva stage of N. denticulata to potassium dichromate compared to the D. magna and the juvenile stage of O. latipes.

The study aims to investigate the nexus of between role identity, self-efficacy, feeling of energy, and employee creativity in the hotel industry of Korea. The employees’ innovative behaviors like creativity have been many researchers’ interest for decades in the hotel industry. The hypotheses depicting the relationship among the variables have been proposed based on a review of existing literature. The number of 215 cases was used for final analysis and the results were explained through structural equation modeling. The results indicate the hotel employees’ role identity and creative self-efficacy positively influenced their feeling of energy. Further, both role identity and creative selfefficacy make significant impact on employee creativity. Feeling of energy also makes a positively significant impact on employee creativity. Feeling of energy partially mediates the relationship between the two independent variables and employee creativity. As a result, creative role identity, self-efficacy, and feeling of energy explain the variance of the hotel employees’ creativity. The results present that hotel practitioners need to regard their employees’ creative roles and build organizational culture to support creative activities so as to enhance employee creativity. Finally, theoretical and practical implications for the hotel industry and future studies have been discussed.

During implantation period uterus undergoes functional and histological changes including cell proliferation, differentiation, apoptosis. This delicate condition is regulated by various factors such as steroid hormones, cytokines, and growth factors. From previous our studies, we showed the spatio-temporal expression of Müllerian inhibiting substance (MIS) and MIS receptor Ⅱ (MISR II) in mouse uteri during pregnancy. In present study investigated the role of MISRⅡ in proliferation and differentiation in the uterus. The decidualization markers were dramatically decreased during treated rhMIS and MISRⅡ viral particles in in vitro decidualization model. The intensity of PAS staining and Oil-Red-O staining were dramatically decreased by treatment of rhMIS and overexpression of MISRⅡ. MIS/MISRⅡ also suppressed stromal proliferation regulate the differentiation of stroma cell during decidualization. MIS suppress the stromal proliferation and decidual differentiation along with its receptor. Put together it is suggested that MIS works as paracrine and autocrine factors for cell proliferation regulator and differentiation regulator during implantation.

In this study, the anti-oxidant and anti-elastase activities of four abalone viscera extracts were investigated to screen the most promising extract. This extract was further studied in terms of its anti-skin-aging properties. In the DPPH-scavenging assay, the Tris-HCl extract showed a 58.60±0.88% radical-scavenging activity, which was followed closely by the ethanol extract that had a 55.40±0.62% scavenging activity. In the anti-elastase assay, however, the ethanol extract showed the significantly highest elastase inhibition activity. Furthermore, none of the extracts had a harmful effect on the human dermal fibroblast, as revealed in the MTT assay. In the cell study, the effect of the ethanol extract at various concentrations on the human dermal fibroblast was investigated. At the 10 μg/mL concentration, the ethanol extract boosted the pro-collagen type I synthesis to 705.30±3.06 ng/mL and reduced the MMP-1 to 54.30±0.80 ng/mL, which was considered the optimum concentration. This is the first study that focused on the anti-oxidant and anti-skin-aging effects of abalone viscera extract. Its results may provide fundamental data for further study.

Four medicinal plants selected from preliminary screening study were evaluated in the aspects of their antioxidant activities in alcohol-intoxicated rats. Rats fed 1% α-tocopherol-supplemented diet as positive control and ones done α-tocopherol-deficient diet as negative control were compared with ones done the plant extract-supplemented diet (n=8). After the administration of the experimental diets for 4 weeks, typical increments in activities of manganese-superoxide dismutase (Mn-SOD) and glutathione peroxidase (GSH-px) indicated in alcohol-intoxicated rats, were not observed in ones fed Lagerstroemia and Ulmus extract-supplemented diet. The content of thiobarbituric acid reactive substance (TBARS), the product of lipid peroxidation, did not increased in rats fed plant extracts-supplemented diet except for Terminalia. From the results, it is concluded that Lagerstroemia and Ulmus have physiologically efficient antioxidant activities.
