Lateral roots of soybean sprouts should deeply affect their quality and marketability. The study was done to compare the effects of ocher, chitosan, corn kennel, tea (Thea sinensis L.) and hard rubber tree (Eucommia ulmoides Oliver) leaf extracts on lateral root formation, growth and morphological characters of the sprouts. Seeds of three cultivars, Pungsannamulkong, Sowonkong and Junjery, were imbibed for 5 hours into their 10% solutions and cultured for 6 days. The cultured sprouts were classified into 4 categories to calculate their composition rates on the base of hypocotyl lengths;>7 cm (A), 4 to 7 cm (B), < 4 cm (C) and not germinated (D), and their morphological characters, fresh and dry weights were measured. Composition rate of A was the lowest in Junjery of the three cultivars, while that of C showed reverse result compared to A. This results was the most distinct in hard rubber tree leaf extracts (HRTLE) of the five treatments. In HRTLE treatment, lateral root formation rate were formed in almost of Sowonkong although reduced in order of Pungsannamulkong and Junjery. However, there was no significant difference between the other treatments. Lateral roots per sprout were the lowest in HRTLE treatment of the 5 treatments. In all treatments except the chitosan treatment, the roots were most formed in Sowonkong but least in Junjery. Sprout length adding hypocotyl and root was the shortest in Junjery compared to the other two cultivars. and was the longest in tea leaf extract treatment but the shortest in HRTLE treatment. The result in total fresh weight of sprouts was similar to that of the sprout length.

Two strains Pleurotus eryngii 'Aeryni' and 'Na' carrying superior traits of a pileus and a earliness of harvest were selected to improve previously bred strains by single crosses. New hybrid, Aeryni 3 (Aeryni10 ${\times}$ Na5) showed superiority to other hybrids in yield, fruit body shape and days for harvest. The new strain, Aeryni 3 was harvested earlier than Keunneutari No. 2 by 2~3 days, and yielded 110.5 g/bottle (850 mL) which was 108% of that of Keunneutari No. 2. The ratio of diameter of pileus and stipe was 1.8 indicating that new stain will be likely low damage rate of fruit body during a distribution, and that was better than 2.1 of Keunneutari No. 2. A sensory test of taste of the new strain showed that 84.7% of evaluation panels selected "very good" while that of Keunneutari No. 2 was 55.5%. In purchasing intent test, 86.9% of panels will buy the new stain whereas 46.8% will buy Keunneutari No. 2 implicating that the new strain will likely be more marketability than previously bred strain.

Purpose - The parcel delivery service(courier) industry all over the world has been expanding its market so far, but its growth has been declining in recent years. In this situation, most parcel delivery companies are having trouble with managing themselves because of the pressure from the customer to increase service level and decrease the rate. The purpose of this study is to provide ways to improve competitive advantages of the parcel delivery service industry by evaluating the multi-period operating efficiency of Korea, Japan and global service providers. Research design, data, and methodology - The data for the period of 2011 to 2014 were collected from the annual reports published by parcel delivery companies. In this study, we analyze the marketability (revenue), profitability (operating profits), and management conditions (net profits) of parcel service companies by combining information on human resources (number of employees) and material resources (total assets and equity). Therefore, the number of employees, total assets, and equity are selected as input variables, and revenue, operating profits, and net profits as the output variables. In this study, DEA (Data Envelopment Analysis) is used to measure the comparative efficiency and MPI (Malmquist Productivity Index) is used to analyze the trend of change of the efficiency for a multi-year period. Results - The operational efficiency scores of medium-sized parcel delivery companies in Korea are higher than other larger competitors such as Korean, Japan and Global larger companies. As of 2014, Logen(1.878) was found to be the most efficient parcel delivery enterprise, followed by KGB (1.224), and Kyoungdong(1.002). Otherwise, Hanjin(0.235), CJ(0.262), Hyundai Logistics(0.657), DHL(0.611), UPS(0.766), FedEx(0.498), TNT(0.350), Yamato(0.762) and Sagawa(0.520), larger sized companies, were done inefficiently. The productivity of parcel delivery companies is influenced by endogenous factors as well as exogenous ones such as changes in business environment and technological advances. Conclusions - Korean medium-sized companies have relatively high efficiency scores in operation. That is why they still survive the competitive market in Korea where market restructuring on the industry has been expected to be conducted for many years. The reason why medium-sized couriers had higher efficient scores than larger couriers is that most of couriers spend more operating expenses versus unit price of delivery which is the amount of money that is needed in order to send a package by parcel service. So the delivery unit price must be taken into account by all the expenses associated with the cost of fuel, labor and maintenance expenses for facilities, etc. therefore, the unit price must be increased to strengthen business competitive power. In order for the industry to have more competitive advantage, the companies need to make profits by increasing demand volume and raising the delivery rate to provide high-quality delivery service to customers. And both endogenous and exogenous change must take precedence in order to strengthen their competitiveness.

Recently, Cucumber mosaic virus (CMV)-P1 infection in pepper cultivation is very serious problem, which causes low marketability and yield. In this research, 56 domestic pepper cultivars including 20 PR (Phytophthora resistance) cultivars, 31 foreign pepper lines collected from USA and 112 genetic pepper resources form RDA Genebank were used for CMV-P1 resistance evaluation. Resistance evaluation was performed at 24 days and 51 days after artificial inoculation of peppers by enzyme-linked immunosorbent assay (ELISA). Among the 36 domestic cultivars 'Muhanjilju' were resistant to CMV-P1. All 20 PR cultivars and 29 foreign peppers except 'NuMex Twilight' and 'Chainese Giant' were susceptible. Among 112 pepper lines from RDA Genebank, nine pepper lines were resistant, and 17 pepper lines were moderately resistant, and 86 pepper lines were susceptible. Almost all domestic peppers on the market were highly susceptible to CMV-P1, whereas 17.2% of foreign pepper cultivars and genetic pepper lines from RDA Genebank were resistant or moderately resistant. Resistant pepper lines selected in this study can be used as genetic sources for breeding CMV-P1 resistant pepper.

Defense technology planning identifies medium-and long-term core technologies to accomplish future defense goals and suggests strategies for future R&D. In order to promote the export-oriented defense industry, planning paradigms should be shifted from technology-oriented planning that focuses on weapon systems to market- oriented R&D planning. This study aims to strategically support 'preliminary technology planning' the Defense Agency for Technology and Quality is pushing ahead with. Through market-orientation analysis models of weapon systems based on defense R&D planning, data research on previous market-oriented research, and the analyses and examples of global defence markets, it evaluates market attractiveness to UAVs and drew methods for exploring markets and enhancing competitiveness of military equipment. The market-oriented analysis model of weapon systems is considered to be a helpful reference as a relevant factor for decision making on establishing and verifying requirement planning. In particular, if a market-oriented defense R&D planning process is established institutionally, it will enable us to make export strategies tailored to different equipment from the planning phase and to support marketing strategically.

In the era of fierce global competition and short product life cycle, firms have been interested in the technology valuation to improve their competitiveness. As the technology valuation may become a key issue for countries and industries, the development of technology valuation method has become increasingly important. Thus, this study aims to suggest a novel method to assess technology value by applying conjoint analysis to bibilographic information of patent. For this purpose, we firstly identified nine patent indexes categorized in three attributes - technological superiority, marketability and legal rights. Then, we collected actual data on patent transactions including their patent attributes and market prices. Based on the data, we could obtain the patent index values. Finally, we applied conjoint analysis to the prices and patent index values as a basis for technology valuation. The suggested method is expected to be an effective tool for technology valuation by using real transaction data rather than relying heavily on experts assessment.

Storage conditions of selling mungbean sprouts should affect their marketability. The study was done to examine the effect of light quality (blue, green, yellow, red, far-red) on greening period, shape, fresh and dry weights of mungbean (cv. Zhong Lu 1) sprouts for 5 days to get some information on designing their various polyethylene envelops with different colors. Periods taking to green were 2 to 3.5 days in blue, red and far-red lights but longer than 6 days in green and yellow lights. Yellow lights had the longest total length adding hypocotyl and root, and blue light did the widest hypocotyl diameter while all light treatments showed similar lateral roots for the period. Total fresh and dry weights were the highest in red light but the least in far-red light. Their lengths and weights in green and yellow lights showing the longest periods for their greening declined with increased storage periods but showed no difference between them, meaning that the envelops should be designed mainly by green and yellow colors.

A packaging and distribution system for transferring individual live squids at low temperature was developed and compared to a conventional bulk container system. Ten live squids in individual packages were stored in a large container at low temperature ($0{\sim}10^{\circ}C$). Live squids in individual packages at $6^{\circ}C$ showed a survival rate of 84% up to 72 hours, after which the survival rate decreased. However, the survival rate remained at 60% up to 120 hours. Further, the squids survived up to a maximum of 7 days. Optimum temperature was $5^{\circ}C$, and the survival rate of the packages was 70% when stored at $5^{\circ}C$ for 96 hours. A distribution test was carried out using a refrigerator truck at $5^{\circ}C$, and the results showed a 100% survival rate up to 16 hours and over 90% survival rate after 20 hours. A rectangular container was the most favorable when loading the container into the refrigerator truck. In testing the required volume of supplied seawater, 100% survival rate was observed over 15 hours with 20 L of sea water or more. Therefore, a single squid needed 2 L of seawater. After refrigerator truck transportation, optimum temperature for fish tank storage was $5^{\circ}C$, at which the survival rate was over 90% up to 72 hours. Using a refrigerator truck at $5^{\circ}C$, live squids survived up to 7 days, maintaining marketability.
