The purpose of this study was to analyze roles and duties of officials in charge of school foodservice in city, province and district 'Offices of Education'. For this purpose, the list of roles/duties of officials was developed through in-depth interviews, content analysis, and delphi technique. The list which includes 56 duty items in 8 dimensions was used for developing a questionnaire. A total of 282 questionnaires from 102 Offices of Education were used for the analysis. The school foodservice officials regarded 'budget management', 'facilities & labor management', 'developing long-term plan', and 'inspection & evaluation' as important. 'Education and research' and ‘management of nutrition, diet, and food materials' showed higher level of importance and need for support compared to its frequencies of work. There was no significant difference among city, provincial, and district Offices of Education on the levels of importance for each area/category. However, 'Officials in the District Offices of Education' needed more support in the area/category of 'facility & labor management'(p < .01). In addition, there was a significant difference between actual and ideal proportion of work in 'education & research'(p < .001), 'management of nutrition, diet and food'(p < .01), 'other supports for school foodservice'(p < .05) amongst the officials in 'City & Province Offices of Education'. For 'officials in the District Offices of Education', actual and ideal proportion of work was different in 'planning & coordination'(p < .01), 'school foodservice program management'(p < .001), 'education & research' (p < .001), 'management of nutrition, diet and food materials'(p < .001), and 'budget management'(p < .001). The results of this study showed that the areas of 'budget management', 'facility & labor management', and 'developing long-term plan', inspection & evaluation' needed more support for 'City & Province Offices of Education'. 'Officials in the District Offices of Education' also needed more support in the areas of 'budget management' and 'facility & labor management'.

The great economic losses caused by Cucumber mosaic virus (CMV) infection of peppers has led to the development of genetically modified (GM) CMV-resistant peppers. We developed virus-resistant pepper plants using Agrobacterium tumefaciens -mediated transformation. The expressed recombinant protein was purified using nickel-nitrilotriacetic acid resin and immunoaffinity chromatography, and purity was assessed by sodium dodecyl sulfate polyacrylamide gel electrophoresis. Immunoblot analysis revealed the purified CMV coat protein (CMV-CP) had a molecular mass of 25 kDa. After in-gel digestion and desalting, the internal peptide fragments of CMV-CP were sequenced by matrix-assisted laser desorption/ionization-time of flight. Most GM pepper and Escherichia coli BL21 internal peptides had identical peptide sequences and contained 137 of 183 whole peptides in CMV-CP. A quantitative enzyme-linked immunosorbent assay was performed to detect CMV-resistant GM peppers. We also provide basic information about the expressed protein in GM peppers for further safety assessment. The contents of soluble protein and CMV-CP were measured in GM and control peppers cultivated in three different areas of Korea. Statistical significance in terms of cultivation areas, harvest times, generations, and plant tissue origin were determined based on a P value of 0.05. The highest amount of CMV-CP was detected at the seedling stage from plant grown in each region. T3 and T5 showed significantly different levels of CMV-CP from T4 in leaves in the whorl stage. No statistical differences were observed among GM peppers at different stages of maturity in any cultivation area. The results from this study contribute to the safety evaluation of newly designed CMV-resistant GM peppers and provide a standard against which to compare other virus-resistant GM peppers.

A total of 80 pigs [(Landrace ${\times}$ Yorkshire) ${\times}$ Duroc] with an average body weight of $72.9{\pm}2.6kg$ were used in the present study to investigate the effects of fermented whole crop wheat and barley with or without supplementing inoculums throughout the restricted feeding in finishing pigs. There were 4 replicate pens per treatment. Pigs were fed ad libitum throughout the experiment as the control (CON), and the other four groups were restricted to 10% in the CON diet and fed ad libitum fermented whole crop cereals: fermented whole crop barley with inoculums; fermented whole crop barley without inoculums; fermented whole crop wheat with inoculums; and fermented whole crop wheat without inoculums. During the entire experiment, the average daily feed intake (ADFI) decreased in the fermented barley and fermented wheat groups compared to the CON, while no difference was observed in the average daily gain (ADG), feed efficiency (gain : feed ratio, G : F) between the control and fermented whole crop barley, wheat diet group. Dry matter and nitrogen digestibility did not show a significant difference among the treatments. In the blood constituents, concentrations of blood urea nitrogen were significantly lower in pigs fed fermented whole crop barley without inoculum diets compared with the other treatments. In conclusion, restricted feeding with fermented whole crop barley and wheat regardless of the supplementing inoculums showed no significant difference in growth performance compared to the CON. This suggests that there is a possibility that fermented whole crop barley and wheat could replace part of the conventional diets.

한류3.0은 기존의 문화콘텐츠 뿐만 아니라 전통문화, 문화예술을 포괄하는 'K-Culture'를 핵심어로 내세우며 한국적인 모든 것을 한류문화콘텐츠의 재료로 삼고 있다. 한류문화콘텐츠는 현재 우리 사회상을 반영하는 중요한 증거적 가치를 지닌 기록물로써 보존할 필요성이 있다. 이러한 사회적 환경과 함께, 본 연구에서는 다양한 한류문화콘텐츠들에 대한 현황분석을 통하여 체계적인 기록관리를 위한 AtoM 기반의 기록관리시스템을 제안하고자 하였다. 최근 한류문화콘텐츠 관리는 K-Pop, K-Food, K-Movie 등 특정분야의 단체가 개별적으로 진행하고 있지만 해당 분야 내에서도 관련 기관간의 연계가 부족하여 정보 축적이 제한적이며 콘텐츠에 대한 재생산 또한 미흡한 실정이라고 할 수 있다. 이에 본 연구는 한류문화콘텐츠의 기록화를 위해 오픈소스 소프트웨어인 Access to Memory(AtoM)를 사용하였다. AtoM은 기록의 수집에서부터 축적 및 분류, 기술, 목록관리, 검색 등의 기록관리 기능을 지원하며 무료로 사용가능한 웹 기반의 소프트웨어라는 장점이 있다. 한류문화콘텐츠의 기록화를 위해 기록관리시스템의 기능요건에 따라 AtoM을 적용하였다. 특히 K-Food와 관련된 기록콘텐츠를 모델로 선정하여 관련 기록물을 수집 및 분류하였으며 ISAD(G) 표준에 맞추어 기술하였다. 마지막으로 AtoM을 이용한 한류문화콘텐츠 기록화에 대한 기대효과와 한계 및 연구의 의의를 밝혔다.

The purpose of the present study was to investigate physicochemical changes in olive flounder and korean rockfish muscle subjected to the cold brine, and to find the optimal immersion condition. Effects of various immersion conditions in a sliced raw fish quality were investigated in the rigor index, breaking strength, ATP related compounds, and lactate accumulation in the muscle. The onset of rigor-mortis was accelerated by the increase of immersion time. Also, the time reaching full rigor was shortened remarkably too. However, the rigor index of samples immersed in the cold brine decreased more than that of samples killed instantly. Rigor index was the highest in samples killed instantly, followed by 2.5 min, 5min, 7.5 min, 10 min and 15 min in order. Breaking strength of all samples immersed in the cold brine decreased significantly after reaching the maximum values. The content of ATP related compounds in olive flounder, korean rockfish were $12.0{\mu}mole/g$ and $8.3{\mu}mole/g$, respectively. However, ATP decreased in the samples immersed in the cold brine. The content of ATP was lower, at the optimal condition and then it was increased. Also, lactates increased, at the optimal condition and then it decreased, in contrast with the ATP. The results suggested that the optimal immersion condition of olive flounder and korean rockfish was at -${12.5}^{\circ}C$ for 5min.

We evaluated the antioxidant activity and anti-wrinkle effects of Aceriphyllum rossii leaf ethanol extract (ARLEE) in vitro using human dermal fibroblasts. The total polyphenol and flavonoid contents of ARLEE were 578.6 and 206.3 mg/g, respectively. At a concentration of $250{\mu}g/mL$, the electron-donating ability of ARLEE was 87.1%. In comparison with the vehicle, ARLEE treatment at $100{\mu}g/mL$ significantly increased type I procollagen synthesis (p < 0.01) by 50.7%. In vitro ARLEE treatment (10 mg/mL) inhibited collagenase and elastase activity by 97.1% and 99.2%, respectively. Compared with the control, ascorbic acid treatment at $100{\mu}g/mL$ significantly decreased matrix metalloproteinase (MMP)-1 protein expression (p < 0.01) by 37.0%. ARLEE treatment at $50{\mu}g/mL$ significantly decreased MMP-1 protein expression (p < 0.01) by 46.1%. Ascorbic acid and ARLEE treatments at $100{\mu}g/mL$ significantly decreased MMP-1 mRNA expression (p < 0.01) by 26.1% and 36.1%, respectively. From these results, we conclude that ARLEE has excellent antioxidant activity and even better anti-wrinkle effects than ascorbic acid in human dermal fibroblasts. These results suggest that ARLEE could be used in functional cosmetics for the prevention or alleviation of skin wrinkles induced by ultraviolet rays.

To evaluate the effect of ground cherry extract on the activity of aniline hydroxylase, we gave ground cherry extract in doses of 100, 200 or 400 mg/kg i.p to mice for 1, 2 or 4 days. The aniline hydroxylase activity in the group treated with ground cherry extract increased in a dose dependant manner in all experimental groups compared with the control group, and was significantly higher in the group treated with ground cherry extract at a dose of 200 mg/kg, which also exhibited a time dependant increase over 4 days. Enzyzme kinetic analysis was performed for hepatic aniline hydroxylase activity in the group treated with 200 mg/kg for 4 days. There was no change of the Km values for aniline hydroxylase between the experimental group and the control group, but the Vmax values for aniline hydroxylase was 21% lower in the experimental group compared with the control. The experimental group also showed lower lipid peroxide and reduced glutathione content, and there were no significant difference in serum alanine aminotransferase activity between the experimental group and the control. Aniline was injected into both the experimental group mice treated with ground cherry extract at a dose of 200 mg/kg for 4 days and the control group, and then the level of blood aniline was assayed at 1hr. The level of blood aniline was lower in the experimental than the control group. This study suggests that ground cherry extract induces hepatic aniline hydroxylase activity and might accelerate the scavenging system of reactive oxygen species. It is likely that ground cherry extract influences the metabolism of xenobiotics by activating AH activity substituted for CYP2E1.

Saengcheonggukjang, known as Natto in Japan, is a soybean fermented food which is made from steamed soybean, Bacillus and water. Demand of Saengcheonggukjang has increased because it does not have much smell compared to Cheonggukjang. Seven varieties of Saengcheonggukjang were investigated and compared in terms of 100 seed weight, quality characteristics, hard seed rate, and water absorption rate in order to determine the suitability of Korean soybeans. In addition, each characteristic of Saengcheonggukjang was compared. 'Hoseo' and 'Haewon' showed low 100 seed weight with 8.41 g and 8.11 g, respectively. The water absorption rate was higher in 'Hoseo' and 'Pungwon' than in Japan varieties. The yield of Saengcheonggukjang was significantly different for each variety. No differences were observed in yield and hardness of Saengcheonggukjang with respect to the varieties and sowing date. 'Haewon' showed the highest amino nitrogen content with 575.0 mg%. Viscous material content did not appear to differ between varieties. These results suggested that 'Hoseo' and 'Haewon' can be considered as suitable candidates for yield and quality of Saengcheonggukjang compared to Japan varieties.
