The overall objective of this study was to determine which variety of carrot-10 Japan varieties or 6 domestic varieties- produces the optimum quality, when cultivated on Jeju Island. Plant height, leaf number and leaf weight were observed to be more superior in the purebred variety ‘Jungang’than other varieties. further studies, however, skewed the crossing variety ‘Bureoun’was superior to all others. Furthermore, when comparing root diameter, root length and root weight, the ‘Bibary’was superior in both the purebred and crossing variety, When researching Japan varieties, the crossing variety, ‘Jung’showed an increase in underground root. The purebred variety ‘Donghae’also showed an increase in underground root. Marketable yields in domestic varieties were greatest in ‘Hapa’, while in Japan varieties, ‘Kaneko’was the most productive. The percentage of root cracked was 15％ greater in ‘Bureon’. In the purebred variety, Jungang, the percentage was only 10％. The percentage of roots branched was highest in ‘Hidomi’which showed a rate of 9%, The roots branched rate was 2% for ‘Jung’and 6％ for‘Donghae’. Considering the percentage of roots clacked or branched, the marketability of carrots was higher in Japan varieties in comparison with domestic varieties. Therefore we conclude that, in the cropping patterns of carrots, the domestic variety has an advantage over the Japan variety.

In this study we surveyed the preferences of consumer packaging for mini pot flower plants to improve the flower market application in Korea. The surveys were consisted of the consumers residing in Seoul metropolitan (221), Gyeonsang (70), Jeonla (29), Chungceong (19), Gangwon (7), other provinces (3). A total of 349 eligible respondents (male 173, female 176) were surveyed with a self-administered questionnaire asking on the general characteristics for residents, packaging material, packaging design, type of flower pot, degree of transparency, convenience, consumer's demand for packaging development, a significant point when purchasing the flower pot product. The collected date was analyzed using a chi-square (${\chi}^2$) statistical test in SPSS program. Most residents prefer for mini pot flower plants packed with packaging characteristics of plastic material (56.4%), packaging design of separated type (76.2%), angled type (62.5%), and transparency (48.6%). The other question results showed that major consumer's demand for mini pot flower plants is maintaining the freshness quality and stability structure for them. Transparency of packaging can also affect directly the preferences for purchasing the mini pot flower plants. The packaging structure with a proper shape design may protect the fresh mini pot flower plants from shock or any other damage during distribution. The results of this study help to provide consumer's demand for packaging development and to give the greatest advantages in terms of production and marketability of mini pot flower plants.

This study investigated the packaging status and sensory quality of fresh-cut mushroom products from retail markets. Fifty one fresh-cut mushroom products were surveyed / purchased from discount stores in four cities in January (winter), March (spring), August (summer), and October (autumn) 2009. Collected fresh-cut mushrooms include single variety products like whole oyster mushroom and winter mushroom, diced or sliced oak mushroom, sliced king oyster mushroom, and ready-to-cook mixed mushroom products. Most fresh-cut mushrooms were packed in trays made of aluminum, polystyrene (PS), polyethylene terephthalate (PET), nylon materials covered with PVC (polyvinyl chloride) wrap or solid PP (polypropylene) and PS. Eighty nine percent of the covers were labeled with manufacture and expiration date. Collected samples showed severe browning (10%) and off-flavor (4%). The percentage of products with a rating of 'good' or better in overall quality was 90%. Moreover, Survey showed seasonal differences in sensory qualities. All of the collected fresh-cut mushrooms in autumn and winter had high marketability. However, Mushroom products collected in spring and summer had lower quality, hence requires treatment to prevent browning and off-flavor.

The effects of calcium concentrations of coating bag treatment to reduce berry cracking were investigated through the changes of pericarp structure and berry cracking rate in 'Kyoho' grape. The soluble solids and anthocyanin contents in harvested grapes were highest at $18.1^{\circ}Brix$ and $2.56{\mu}g{\cdot}cm^{-2}$ in non bagging group compared with those of calcium coating bag treatments. The firmness of pericarp was lowest in non bagging group ($1.18kg{\cdot}5mm^{-1}{\O}$) compared with bagging treatments (1.23, 1.24, 1.27, $1.35kg{\cdot}5mm^{-1}{\O}$) which increased effectively in proportion to calcium concentration. As a result of histological observation of the fruit skin, the bagging with higher calcium concentration developed thicker epidermal and sub-epidermal layer of cell wall than that of non bagging. Moreover, the strengthened berry skin of calcium treatments effectively decreased berry cracking rate under critical turgor pressure. However, the 9% calcium coating bag treatment which was the most effective for cracking reduction seriously decreased marketability of harvested grape with white color staining on berry skin caused by eluted calcium from the coated paper bag. Based on our results, we recommend that 6% calcium coating bag be available for berry cracking reduction and higher quality production.

The wearable technology takes the concept of clothing over its limits -integrating software, communication devices, and sensors into the garments to enable them to 'think' for the wearer. A dress is no longer just a dress, but a dress as well as a wearable computer interface. This wearable computer network transports the data power and control signals within the wearer's personal space. The purpose of this thesis is to explore the wearable technology from a commercial perspective. On this theme I made a survey and interviewed 20 men and 20 women in London to find out if many people are familiar with the concept of the wearable technology. The main results of this study include: Firstly, according to the survey, people are not familiar with the concept of the wearable technology, and further people thought negatively about the wearable computer rather than positively they worried about hish prices, inappropriate technology and side effects. Secondly, people are especially interested in items related to health and security, so in this area there are huge potential opportunities for the wearable technology, Finally, wearable technology needs to be a simplified set of interactive devices, which are in a user friendly format for marketability because convenience was one of the biggest concern for consumers. Therefore, development of the wearable computer should be promoted not only through computer engineering but also through the connection with human lift.

This study investigated the effect of different $O_2$ transmission rate (OTR) of films on surface temperature, weight loss, pH, $O_2$, $CO_2$ and sensory characteristics, microbial quality, total phenolic contents and 1,1-diphenyl-2-picryl hydrazyl radical scavenging activity of fresh-cut lettuce during storage at $10^{\circ}C$ for 7 days. $80{\pm}5g$ of fresh-cut lettuce were packaged with oriented polypropylene films respectively. The OTR of packaging materials was 5,000, 8,000 and $10,000cc/m^2{\cdot}day{\cdot}atm$. Quality characteristics showed significant differences during storage. The surface temperature was averaged 13 and lower in higher OTR of films. The weight loss of lettuce ranged from 2.8 to 5.4% and the highest loss showed in $5,000cc/m^2{\cdot}day{\cdot}atm$ of film. pH was increased during storage and the highest pH was found in $5,000cc/m^2{\cdot}day{\cdot}atm$. The $O_2$ content in the packaging was decreased with increasing $CO_2$ content during storage. The lowest $CO_2$ was found in $10,000cc/m^2{\cdot}day{\cdot}atm$. As OTR was decreased, antioxidant profile of lettuce was decreased. Total aerobic bacteria showed from 5.48 to 6.59 log CFU/g. From the result of the overall sensory test, the marketability of fresh-cut lettuce stored at $10^{\circ}C$ seemed to be maintained effectively over 5 days.

This research refers to the importance of health care in relation to the establishment of health care facilities and health care facilities in the rapidly changing health care environment, and the influence of health care in relation to the customer's satisfaction with health care. Orthographic analysis First, a hypothesis was adopted that the attractiveness of building materials will affect the positive (+) impact of the customer's satisfaction. Second, the hypothesis that the transport infrastructure will have a significant impact on the customer's satisfaction with the customer's satisfaction has been denied. Third, the hypothesis that the building appeal will have a significant effect on the health of the medical industry is adopted. Fourth, the hypothesis that the transport infrastructure will have a significant impact on health care is adopted. Fifth, the hypothesis that medical integration will have a significant impact on the customer's satisfaction with the customer's satisfaction is adopted. Sixth, the hypothesis that the relationship between the building and the customer's satisfaction in relation to the relationship between the client and the client was found to be partly attributable to the fact that there was a partial role. The assumption that the relationship between the transport infrastructure and the customer's satisfaction in relation to the traffic infrastructure was established has been identified as a complete parameter. The results of this study could be applied to provide the basis for selecting the location for future health care facilities.

In order to facilitate the R&D of SMEs and foster innovative SMEs, the Small and Medium Business Administration is funding the SMEs in the focused supporting industries which are selected by a primary consideration of the political conformity. The correlations among the distribution of engaged SMEs, the distribution of SMEs which applied the fund, and the distribution of SMEs funded in the industries are analysed, in order to realize the effectiveness of the top-down method for selecting the focused supporting industries. As a result, there was a large deviation of both the number of the engaged SMEs and the number of the applied SMEs in the each industry, which means that the selected industries did not accurately reflect the needs for the technology development of SMEs. In addition, the distribution of the applied SMEs was strongly depended on the distribution of the engaged SMEs, which shows the trend that SMEs are trying to make R&D plans in their current industry rather than following the political drive. Moreover, because the distribution of the funded SMEs is strongly correlated with that of the applied SMEs, one could know that the selected industries were neither fostered strategically nor evenly but the fund was distributed simply according to the distribution of the applied SMEs. In this study, in order to complement the limitations of the top-down method, the bottom-up method which primarily consider the needs for the technology development of SMEs was suggested. It is desirable to consider in the order of the needs and the capabilities of SMEs, the technological perspective and marketability of the industry, and the political importance in the bottom-up method, and it is expected that the method could be flexibly used in the planning of the various programs.

With recent increase in growth without employment and unemployment rate, Business Incubator (BI), which is the birthplace of business start-up, is drawing much attention. Therefore, numerous studies had been carried out from the perspectives of efficient operation and performances of BI. Preceding studies at home and abroad were concentrated mainly on the effect of Critical Success Factors of BI on performance, or on internal operational programs or support services of BI. Recently, assertion that potential capacity of companies located in BI at the time of their commencement of occupancy imparts effect on the performance has been presented. Therefore, this Study, in order to pursue research on above issues, will, firstly, analyze the effect of the characteristics of evaluation of companies wishing to be located in BI conducted by each BI, and, secondly, regulation effect of characteristics of evaluation of companies wishing to be located in BI imparted on performance in connection with the work capabilities of BI and capabilities of manager. The results of analysis illustrated that the expertise, among the capabilities of CEO, imparts affirmative effect on the success rate of business start-up. Product competitiveness and marketability displayed affirmative effect on the success rate of business start-up when work capability (operational intensity) is applied. In particular, although the financing capability of CEO of the company located in BI, as an important factor, imparts negative effect on the success rate of business start-up, it implies affirmative regulation effect through the capabilities of manager.

Web traffic is becoming an important indicator to make inferences about internet companies' future prospects so that traditional firm valuation methods need to be modified to integrate the ideas of web traffic information as a major asset of internet companies. It is because web traffic is a measure of attracting visitors to firm's web site and is the basis for internet companies' marketing expenditure and customer acquisition and retention. Also the web traffic represents the internet companies' technological advances and marketability. The major purpose of this study is to show the relevance of web traffic for valuation of internet companies. For this, we test hypothesis with the firm's web traffic and financial data using the analysis model of Hand(2000a) derived from the log-linear model introduced by Ye and Finn(1999). Test results show that the web traffic, more specifically the number of unique visitors, visits, and page views are all positively related to the firm's value. This implies that the web traffic information should be considered as one of the important non-financial indicator for the internet firm valuation.
