This study was conducted to find out the effects of over seeding using new grass varieties orchardgrass ‘Kordione’ and ‘Onnuri’, and tall fescue ‘Greenmaster’ on botanical composition and dry matter productivity from 2013 to 2016 in low productivity hilly pasture, middle area of Korea. There were used 3 grass seed mixture types made of different compositions and amounts {T1: control - no over seeding, T2: tall fescue (TF) ‘Greenmaster’ 18 kg ha-1, orchardgrass (OG) ‘Kordione’ 9 kg ha-1, Perennial ryegrass (PRG) ‘Linn’ 5 kg ha-1, and Kentucky bluegrass (KBG) ‘Kenblue’ 2 kg ha-1, T3: TF ‘Greenmaster’ 9 kg ha-1, OG ‘Kordione’ 18 kg ha-1, PRG ‘Linn’ 5 kg ha-1, and KBG ‘ Kenblue’ 2 kg ha-1, T4: TF ‘Greenmaster’ 9 kg ha-1, OG ‘Onnuri’ 18 kg ha-1, PRG ‘Linn’ 5 kg ha-1, and KBG ‘Kenblue’ 2 kg ha-1}. In the botanical composition of grassland, T1 nearly remained constant in other seasons while ratio of weeds were increased in summer season. T2 was better than control (T1) in portion of grass ratio, which has increased by 80%. In the early time of establishment, the portions of OG were increased in T2, but TF rate was increased after 3 years later when grass was established. T3 and T4 showed a very similar patterns, grass ratio had increased by 80% and the portion of KBG had increased as time passed. T2 (129,763 kg ha-1) was showed the highest dry matter yield than other treatments (T1: 6,756 kg ha-1, T3: 9641, and T4: 10,738) in 2016.

본 연구는 국내 코스닥시장에 상장된 중소기업이 2010년부터 2014년까지 5년간 해외 및 국내에서 IR 활동을 실시한 것이 주가에 어떠한 영향을 미치는지를 분석하였는 바, 주요 연구 결과는 다음과 같다. 첫째, 국내외 IR 실시는 주가에 긍정적인 영향을 미치면서 주가를 한 단계 레벨업시키는 것으로 나타났다. 둘째, 단기적으로는 국 내 IR이 해외 IR보다 주가에 보다 긍정적인 영향을 미치는 것으로 나타났다. 셋째, 외국인지분율이 매우 낮은 코 스닥기업의 경우에는 효율성 측면에서 해외 IR보다는 국내 IR에 보다 집중하는 것이 나았다. 넷째, 개별기업이 주관하여 IR을 실시하는 것이 한국거래소(KRX) 주관 IR보다 주가에 훨씬 더 긍정적인 영향을 미쳤다. 다섯째, 외국인지분율이 높은 코스닥기업일수록 IR 실시에 따른 긍정적인 주가 반응이 상대적으로 낮게 나타났다. 이는 부분적으로 외국인투자자와 경영자 간의 정보비대칭성이 덜하기 때문으로 해석된다. 여섯째, 수익성이 높은 기업 일수록 IR 활동이 주가에 더욱 긍정적으로 영향을 미침으로써, 코스닥 중소기업들은 수익성이 뒷받침되는 경우 적극적으로 IR을 실시하여 기업가치를 높여야 할 것임을 시사한다. 일곱째, 동일 분기 내에 IR을 여러번 실시하 는 경우 주가에는 오히려 덜 긍정적으로 작용하였다. 또한 규모가 큰 코스닥기업은 해외 IR을 실시함으로써 주가 에 더 긍정적인 영향을 받고 있었다. 결론적으로 한국 중소기업의 국내외 IR 활동은 주가에 긍정적인 영향을 미 치는 것으로 나타난 반면, 국내주식시장의 개방과 국제자본시장의 통합 진전으로 인해 국내 IR과 해외 IR의 주 가영향력에는 크게 차이가 없는 것으로 나타났다. 그러나 IR 활동 자체는 기업가치를 높이는 효과가 여전히 존재 하므로 향후 국내 코스닥 중소기업들도 더욱 적극적으로 IR 활동을 수행해야 할 것으로 기대된다.

Even though the red pepper is one of the most important seasoning vegetables in Korea, the volume of usage of domestic red pepper has shrunk due to decrease in consumption. Thus, researchers and government officers need to seek for solutions to extend usage of domestic red pepper of food processing industry which consumes considerable amount of it. The purpose of this paper is to analyze the factors of the usage of domestic red pepper in food processing companies using cross-tabulation analysis and multiple regression model and to find the implications for promoting the usage of domestic red pepper. The results of studies present that specific characteristics of food processing companies affect the usage of domestic red pepper, including size of sales, shape of company, food product processed by company, human organization for purchase of food material, registered trademark, and support of government. This study also suggests that government needs to offer more supporting programs to sauce industry and improve the system of program to promote the usage of domestic red pepper.

Climate change resulted in the growing occurrence frequency of typhoons, and the damage it caused was also increasing. In this study, the soundproofing and windproof walls installed on the domestic road were modeled by using ABAQUS, a commercial finite element analysis program. Correspondingly, steel column, aluminum frame and transparent acrylic plate were modeled. Based on the result from individual part of soundproof wall model, the number of soundproof wall parts for optimal design was determined to be five parts. The design standard of road construction barrier was applied to this optimum model to perform the safety evaluation for strong wind disaster. In the future, it will be possible to improve the guidelines for design of soundproofing walls in Korea by carrying out further experiment to increase the reliability of safety evaluation of soundproofing walls.

Nowadays, container transport services play a substantial role in global cargo transportation by serving as an intermodal between the exporter and importer. Container shipping has become increasingly important over the past few decades due to its obvious advantages. However, Vietnam's container market has shown severely ongoing competition among numerous domestic and foreign shipping lines resulting in serious consequences occurring such as the freight rates substantially decreasing within the last ten years. In fact, Vietnam's sea lanes have become more defensive to cover the losses of shipping companies. Selection of criteria for competitive evaluation of container transport companies is necessary to help recognize the problems within the enterprise especially relating to its position in the market and from here, business management are able to put strategic plans in place and reasonable policy in order to be able to survive and grow.

The frequency and time of the outbreak of insect diseases were investigated among the insect-rearing farms by regional groups. The purpose of this study was to predict the insect diseases and reduce the spread of diseases. From February to October 2016, 87 of diseased insects were collected in seven regions. It turned out that the pathogens for fungal diseases were identified as Metarhizium anisopliae. But in case of bacterial diseases, the pathogenicity of the bacteria isolated from the diseased insects were not confirmed. Bacterial diseases occurred mainly in June and August in Gyeonggi-do and Gangwon-do, while in Chungcheong-do, bacterial and viral disease raged. In Jeolla-do, both fungal and bacterial diseases occurred in June. Generally, bacterial diseases occurred mainly from June to October, while the frugal diseases occurred from January to March. It was concluded that the entomopathogenic fungi, Metarhizium anisopliae, tended to cause diseases during late-winter and early spring and bacteria, uncertain, was prone to cause diseases during summer. Therefore, it necessary to adequately control depending on the type of the entomopathogen.

This study was investigated the effect of heating time (taken the pots transplanted perennial root in heating greenhouse from Dec. 30 to Mar. 2 as 10 days interval) after 1st cut-flower harvesting on the growth, flowering time, and cut-flower productivity of domestic bred Gypsophila paniculata ‘Dream Song’ in plain area. As the later heating time, the shorter days to shoot emergence and flower budding as the longer exposed to low temperature, and blooming was promoted with increasing the air temperature within greenhouse. Flower stalk length, node number, and stem diameter were inclined to decline in later heating time. In Dec. 30 heating time, node number on a main stem was many, but primary branches number was low due to insufficient breaking of dormancy. Cut flower length was not significantly different as affected by heating time, fresh weight got declined as the later heating time and then drastically decreased in Mar. 2. Cut-flower yield was not significantly different among heating time except for both Dec. 30 insufficiently exposed to low temperature and Mar. 2 shortened the growth duration caused by relatively high temperature. It was thought that the dormancy of ‘Dream Song’ broke after the middle of January under natural low temperature, and the production of second crop should be cultivated within Feb. 20 from mid January.

Recently, de-industrialization phenomenon has been intensified in global. It caused negative issues of manufacturing economy, so many countries are carrying out a policy to protect and promote their manufacture industry. Also in Korea, government is implementing a policy to promote their manufacture based technique and process. It was named "Ppuri industry". We studied how important Ppuri industry is in Korean manufacture economy and the relation of between the metal industry and Ppuri industry. Finally, we analyze the problem of korean promotion policy of Ppuri industry and suggest an alternative policy.

We explore each of the three major domestic fishery product markets in South Korea- Frozen Squid, Frozen Hair tail and Dried Anchovy- to assess whether we can find evidence for Law of One Price (LOP) across the five major cities- Seoul, Dae-Jeon, Dae-Gu, Gwang-Ju and Busan. To achieve our aim, we utilize two different types of unit root tests: Augmented Dickey-Fuller (ADF) and Kwiatkowski-Phillips-Schmidt- Shin (KPSS) unit root test. In each of the three fishery product markets, we find evidence in support of LOP among several cities, which confirms that these markets are integrated to a certain extent. In particular, we find stronger evidence of LOP for Dried Anchovy market relative to the other two fishery product markets. Based on our findings, we argue that the Dried Anchovy market exhibits a greater degree of market integration across the five major cities in South Korea compared to the other two fishery product markets. The greater degree of market integration in the Dry Anchovy market is facilitated by its higher substitutability across cities; taken together these findings show that the market for Dried Anchovy in South Korea is more efficient than the markets for Frozen Squid and Frozen Hair tail.

Mold is one of the important bio-aerosols affecting human health in the indoor environment. To manage mold contamination, it is necessary to use an appropriate method for its detection and enumeration. Recently, the impaction method of ISO 16000-18 has been established as one of methods to detect and enumerate molds in air. To investigate the general use of the impaction method for mold detection in domestic indoor environments, the suitability of the method was assessed using different antibiotics, media and air samplers. All of the three antibiotics tested - ampicillin, chloramphenicol and streptomycin - showed inhibitory effects on bacterial colony formation on MEA and DG-18 media, without inhibiting mold growth. Of these three antibiotics, ampicillin was the most effective. There was no statistical difference between MEA and DG-18 media in the measurement of mold concentration. The formation of discriminative colony morphology was more apparent in DG-18 media. No significant difference in the measurement of mold concentration was found between Andersen samplers and MAS- 100NT samplers, which are two major samplers introduced in Korea.

The fisheries industry has led the Korean economy, and has been achieving high-level position in the world. However, this industry meets aging, low growth and profit. In order to overcome this critical situation, it is needed to understand the overall status of industry. In industry level, most of previous researches focused on ocean industry rather than fisheries. In addition, scholars have been getting a lot of attention about fisheries cooperatives, fishing-ports, methods of fishery, and manufacturing process in fisheries sector. The aim of this research is analysis of domestic fisheries industry’s managerial performance using data envelopment analysis(DEA) considering operating and scale view. Furthermore, the comparative analysis is performed by firm size, and industry type. In results, fisheries industry’s managerial performance is not high, overall. In more detail, most of big size firms are under decreasing returns to scale(DRS) status. Fishery processing industry’s performance is low, and fishery distribution industry has the best performance. This paper suggests that transferring operating capability from big firms to small firms, and policy supports and firm’s activities should be accompanied for high-value added in fisher, and fishery processing industries.

The purpose of this study was to analyze the current status relating to food packaging and design for status of small and medium food enterprises. A company survey was conducted from June to October, 2015 and targeted 1300 small and medium domestic food enterprises. Finally, a total of 1300 (recovery rate 100%) useable data were selected. Statistical analyses were performed on the data utilizing the SPSS PASW Statistics 18.0 for Windows, such as descriptive statistics and frequency analysis. According to the results, awareness and importance of food labeling were high, but performance of English inscription of product name was relatively low. The most important reason for food labeling was ‘providing correct information on food’ 910 (72.8%). Accordingly, a system which can provide the latest information by continuously monitoring mandatory disclosure requirements for types of foods in individual countries is needed.
