Recently, ESG(Environmental, Social, Governance) has been recognized as an important factor for the sustainable growth of companies. However, only 14.5% of food manufacturing companies have adopted ESG management. In particular, small and medium-sized enterprises(SMEs) face difficulties in implementing ESG management due to a lack of specialized personnel and resource constraints. The purpose of this study is to analyze the impact of ESG ratings on the management performance of 40 food manufacturing companies listed on the Korea Exchange(KRX) that have been evaluated for ESG. The one-way ANOVA was used and performed on data for 40 food manufacturing companies published by the Korea Institute of Corporate Governance and Sustainability(KCGS) in 2023. The results of the analysis showed statistically significant differences in sales (F=12.936, p<0.001) and foreign ownership (F=7.74, p<0.01) based on ESG ratings. Furthermore, Scheffe's post-hoc analysis indicated that the higher the ESG rating and individual scores, the better the overall management performance. Therefore, it is concluded that food manufacturing companies should continuously invest in and focus on ESG management to secure a competitive advantage in the market and achieve sustainable growth.

소음공해를 방지하기 위한 방음시설물로서 도로, 철로 및 공항 주변에 설치되는 방음벽은 주로 외부에 설치되어 풍하중에 노출된다. 지속적이고 반복적인 풍하중은 방음벽의 피로를 야기하며 높은 풍속이 발생할 경우 붕괴되는 경우도 흔히 발생하고 있다. 본 논문에서는 반사형, 통풍형 등 방음벽의 유형별로 방음벽에 작용하는 풍하중의 발생 과정과 내풍성능 개선방안에 대해서 전산해석을 수행하였다. 통풍형 방음벽의 경우 수압면적이 감소한 것에 비하여 풍하중은 다소 낮은 6.76%의 감소율이 나타난 원인은 풍하면의 통풍공 주변에 발달한 국부적 부압으로 판단되었다. 추가적인 풍하중 저감을 위하여 박리에 의한 와류의 규모를 개선하기 위한 방안으로 상부에 슬릿을 설치한 결과, 최대 14.67%의 감소효과를 나타내었다. 또한 슬릿의 간격이 250mm일 때 15.41%로 풍하중이 감소율이 상대적으로 우수하였으며, 이는 방음벽 상단과 슬릿에 의한 기류의 상호작용이 와류의 규모와 발달에 영향을 미친 것으로 판단된다.

This study was carried out to investigate the reproductive and growing performances in sow farms located in Chungnam. Data collected from a total of 15 sow farms divided into 3 farm groups for 1 year were analyzed. The results obtained were as follows; The average of sow at small and large farms were 114.25 and 487.88 heads, respectively. And then, the difference among 3 groups in sow farm was not found significantly in farrowing rate. The significant difference among 3 farm groups was significantly found(p<0.05) in total litter size. The litter size born alive at sucking in small sow farm and middle farms were 9.93, and 10.48 pigs. The difference between small and large farms in number of pigs at weaning were significantly shown 8.89, and 9.35 pigs(p<0.05), respectively. The difference among 3 sow farms for ages at weaning showed significantly (p<0.05). The cycles of farrowing rate per year in small, large and middle farms were 2.17, 2.23 and 2.32, respectively. The significant difference among 3 sow groups was found in farrowing rate(p<0.05). The growing rate up to weaning for middle farms was significantly the higher level(94.70%) than that for other farms(p<0.05). The differences among 3 farm groups for marketing weight were not significantly shown.

본 논문에서는 MPEG-7 서술자 (descriptor) 들을 이용하여 바이오 동영상들의 특징을 분석하고， 각 서술자별 검색 효율을 비교한다. 바이오 동영상 검색을 위해 MPEG-7의 칼라 (color) ，텍스쳐 (texture) 그리고，모션 (motion) 서술자들을 이용하여 바이오 동영상들로부터 특정 값을 추출하고， 추출된 원소들의 분산과，가설 검증을 이용하여 바이오 동영상의 특징을 분석하였으며，바이오 동영상 검색에 효율적인 소틀을 찾을 수 있었다. 또한 검색 실험을 통하여 각 서술자들의 바이오 동영상에 대한 검색 효율을 비교하였으며，끝으로 서술자들의 적용 가능 여부를 확인하였다.

This paper discusses the analysis of financial ratios of the Korean coastal passenger shipping company 1997 and 2000. Coastal passenger shipping company shows a very high ratio of the fixed-assets because these shipping company own relatively expensive ships. The current debts are composed of short-term borrowings and lease and the ratio of the current debts is rather high considering to the size of shipping company. The equity ratio of passenger shipping company has recently been decreased, but the debt ratio has been increased. Both the profitability and activity ratios have grown worse in recent years. In order to improve the performance of coastal passenger shipping company, they should develop the leisure facilities and good items to attract travellers.

As a result to check basic physical characteristics of plyood and fabric board, both of them satisfied the criteria of KS F 3126 but hardened fabric board only showed changes in the absorption width expansion rate. This may imply that continuous expansion and swelling can occur if hardened fabric board is exposed to moisture for longtime, and it should be considered when selecting a product and mainteaning it.
