Introduction The purpose of this research is to develop overall model which involves the effect of ongoing support services by franchisor on franchisee's relationship quality(trust, satisfaction, and commitment) and business performance(financial and non-financial performance), and to investigate the relationships among trust, satisfaction, commitment, financial and non-financial performance. This study also suggests franchise business or franchise system should be based on long-term orientation between franchisor and franchisee rather than short-term orientation, or transactional relationship, and proposes the most effective way of providing on-going support services by franchisor with franchisee thru symbiotic relationship among franchisor and franchisee Research Model and Hypothesis The research model as Figure 1 shows the variables on-going support services which affect the relationship quality between franchisor and franchisee such as trust, satisfaction, and commitment, and also analyze the effects of relationship quality on business performance including financial and non-financial performance We established 12 hypotheses to test as follows; Relationship between on-going support services and trust H1: On-going support services factors (product category & price, logistics service, promotion, information providing & problem solving capability, supervisor's support, and education & training support) have positive effect on franchisee's trust. Relationship between on-going support services and satisfaction H2: On-going support services factors (product category & price, logistics service, promotion, information providing & problem solving capability, supervisor's support, and education & training support) have positive effect on franchisee's satisfaction. Relationship between on-going support services and commitment H3: On-going support services factors (product category & price, logistics service, promotion, information providing & problem solving capability, supervisor's support, and education & training support) have positive effect on franchisee's commitment. Relationship among relationship quality: trust, satisfaction, and commitment H4: Franchisee's trust has positive effect on franchisee's satisfaction. H5: Franchisee's trust has positive effect on franchisee's commitment. H6: Franchisee's satisfaction has positive effect on franchisee's commitment. Relationship between relationship quality and business performance H7: Franchisee's trust has positive effect on franchisee's financial performance. H8: Franchisee's trust has positive effect on franchisee's non-financial performance. H9: Franchisee's satisfaction has positive effect on franchisee's financial performance. H10: Franchisee's satisfaction has positive effect on franchisee's non-financial performance. H11: Franchisee's commitment has positive effect on franchisee's financial performance. H12: Franchisee's commitment has positive effect on franchisee's non-financial performance. Method The on-going support services were defined as an organized system of continuous supporting services by franchisor for the purpose of satisfying the expectation of franchisee based on long-term orientation and classified into six constructs such as product category & price, logistics service, promotion, providing information & problem solving capability, supervisor's support, and education & training support. The six constructs were measured agreement using a 7-point Likert-type scale (1 = strongly disagree to 7 = strongly agree)as follows. The product category & price was measured by four items: menu variety, price of food material provided by franchisor, and support for developing new menu. The logistics service was measured by six items: distribution system of franchisor, return policy for provided food materials, timeliness, inventory control level of franchisor, accuracy of order, and flexibility of emergency order. The promotion was measured by five items: differentiated promotion activities, brand image of franchisor, promotion effect such as customer increase, long-term plan of promotion, and micro-marketing concept in promotion. The providing information & problem solving capability was measured by information providing of new products, information of competitors, information of cost reduction, and efforts for solving problems in franchisee's operations. The supervisor's support was measured by supervisor operations, frequency of visiting franchisee, support by data analysis, processing the suggestions by franchisee, diagnosis and solutions for the franchisee's operations, and support for increasing sales in franchisee. Finally, the of education & training support was measured by recipe training by specialist, service training for store people, systemized training program, and tax & human resources support services. Analysis and results The data were analyzed using Amos. Figure 2 and Table 1 present the result of the structural equation model. Implications The results of this research are as follows: Firstly, the factors of product category, information providing and problem solving capacity influence only franchisee's satisfaction and commitment. Secondly, logistic services and supervising factors influence only trust and satisfaction. Thirdly, continuing education and training factors influence only franchisee's trust and commitment. Fourthly, sales promotion factor influences all the relationship quality representing trust, satisfaction, and commitment. Fifthly, regarding relationship among relationship quality, trust positively influences satisfaction, however, does not directly influence commitment, but satisfaction positively affects commitment. Therefore, satisfaction plays a mediating role between trust and commitment. Sixthly, trust positively influence only financial performance, and satisfaction and commitment influence positively both financial and non-financial performance.

Animal infectious diseases, such as avian influenza and foot and mouth disease, occur almost every year and cause huge economic and social damage to the country. In order to prevent this, the anti-quarantine authorities have tried various human and material endeavors, but the infectious diseases have continued to occur. Avian influenza is known to be developed in 1878 and it rose as a national issue due to its high lethality. Food and mouth disease is considered as most critical animal infectious disease internationally. In a nation where this disease has not been spread, food and mouth disease is recognized as economic disease or political disease because it restricts international trade by making it complex to import processed and non-processed live stock, and also quarantine is costly. In a society where whole nation is connected by zone of life, there is no way to prevent the spread of infectious disease fully. Hence, there is a need to be aware of occurrence of the disease and to take action before it is distributed. Epidemiological investigation on definite diagnosis target is implemented and measures are taken to prevent the spread of disease according to the investigation results, simultaneously with the confirmation of both human infectious disease and animal infectious disease. The foundation of epidemiological investigation is figuring out to where one has been, and whom he or she has met. In a data perspective, this can be defined as an action taken to predict the cause of disease outbreak, outbreak location, and future infection, by collecting and analyzing geographic data and relation data. Recently, an attempt has been made to develop a prediction model of infectious disease by using Big Data and deep learning technology, but there is no active research on model building studies and case reports. KT and the Ministry of Science and ICT have been carrying out big data projects since 2014 as part of national R &D projects to analyze and predict the route of livestock related vehicles. To prevent animal infectious diseases, the researchers first developed a prediction model based on a regression analysis using vehicle movement data. After that, more accurate prediction model was constructed using machine learning algorithms such as Logistic Regression, Lasso, Support Vector Machine and Random Forest. In particular, the prediction model for 2017 added the risk of diffusion to the facilities, and the performance of the model was improved by considering the hyper-parameters of the modeling in various ways. Confusion Matrix and ROC Curve show that the model constructed in 2017 is superior to the machine learning model. The difference between the2016 model and the 2017 model is that visiting information on facilities such as feed factory and slaughter house, and information on bird livestock, which was limited to chicken and duck but now expanded to goose and quail, has been used for analysis in the later model. In addition, an explanation of the results was added to help the authorities in making decisions and to establish a basis for persuading stakeholders in 2017. This study reports an animal infectious disease prevention system which is constructed on the basis of hazardous vehicle movement, farm and environment Big Data. The significance of this study is that it describes the evolution process of the prediction model using Big Data which is used in the field and the model is expected to be more complete if the form of viruses is put into consideration. This will contribute to data utilization and analysis model development in related field. In addition, we expect that the system constructed in this study will provide more preventive and effective prevention.

We investigated the change of the blink rate by wearing soft contact lens(SCL). Eight types of soft contact lenses were worn by twelve asymptomatic contact lens wearers. When wearers were worn SCLs for 15 min, the average blink rate was 20.0 blinks/min, which was a statistically significant increase compared to 13.3 blinks/min, the average blink rate of non-SCL-worn eye. After 8 hr of lens wear, the average blink rate was 24.3 blinks/min, and it was 11 blinks/min more than that of non-SCL-worn eye and 4 blinks/min more than that of 15 min SCL-worn eye. There were a little difference of the blink rate in types of lens, which the blink rate range of all lens after 15 min of lens wear was 18.1~20.9 blinks/min and that after 8 hr of lens wear was 22.9~24.9 blinks/min. When wearing A lens(vifilcon, 0.06 mm) having thin center thickness, wearers showing difference of 10.0~11.9 blinks/min between non-SCL-worn eye and 15 min SCL-worn eye reached 16.7% and it was more than that of relatively thick B lens(0.17 mm) and C lens(0.14 mm). This result suggest that the center thickness was not unique factor of the blink rate change and other factors would have synthetically influence on the blink rate change. In the case of B lens and C lens of hilafilcon material but having different center thickness and water content, wearers increasing more than 4.0 blinks/min after 8 hr of lens wear was 58.3% and 41.7%, respectively. This result have provided information that the lenses of similar materials but different center thickness and water content could cause individually the different change of the blink rate.

In order to select the raspberry cultivars that have high contents of bioactive constituents and high antioxidant activities, 7 cultivated and 2 wild raspberries which were selected and cultivated in the Bokbunja Institute were evaluated for their physicochemical characteristics, bioactive constituents, and antioxidant activities. The wild raspberry of Asan was the smallest among the sample raspberries but it had the highest sugar and lowest acid contents among the raspberries. Another wild raspberry of Ulleungdo had the highest total phenolic compound and ellagic acid contents, 182.97, $55.25mg{\cdot}100g^{-1}FW$, respectively, although it was small and had low sugar and high acid contents. Among the widely cultivated raspberry cultivars in Kimhae, 'Wangttal' cultivar was a big raspberry with 12.80% sugar content, and another unknown raspberry cultivar was as small as the wild raspberry with 14.60% sugar content. Although 'Wangttal' and the unknown raspberry cultivars cultivated in Kimhae possess lower contents of total phenolic compound (159.62, $165.94mg{\cdot}100g^{-1}$) and ellagic acid (45.7, $52.1mg{\cdot}100g^{-1}$ ) than the wild raspberry of Ulleungdo, the contents of total flavonoids (14.28, $14.90mg{\cdot}100g^{-1}$) and total anthocyanins (28.69, $30.48mg{\cdot}100g^{-1}$) were higher. Also the wild raspberry of Ulleungdo, 'Wangttal', and the unknown raspberry cultivar of Kimhae had higher antioxidant activities measured by FRAP (Ferric reducing antioxidant power), DPPH (2,2-diphenyl-1-picrylhydrazyl), and ABTS (2,2' azinobis-(3-ethylbenzothiazoline-6-sulphonic acid) assays. The present study shows that three raspberry cultivars could be potent resources for raspberry breeding and functional material development.

This study aimed to analyze the contents of rutin, procyanidin B3, quercetin, and kaempferol, known to have antioxidant, anti-inflammatory, and anti-carcinogenic effects, among the polyphenol types contained in grape pruning stem extracts (GPSE). It utilized grape stems discarded after harvest to measure the effects of GPSE on skin moisture, inhibition of skin cell proliferation, and anti-inflammatory activity on the damaged skin of HR-1 mice induced with ultraviolet B (UVB), and to verify the applicability of GPSE as a material for functional food and functional cosmetics. The polyphenol was extracted from grape pruning stems with 80% EtOH, and then the extract was used while storing at $-20^{\circ}C$, after filtering, concentrating, and freeze-drying it. The content of an active ingredient of GPSE was analyzed using high performance liquid chromatography (HPLC). From 53 kg of the grape pruning stem specimen, 2.34 kg of the EtOH fraction extracts were extracted to achieve a 4.42% yield ratio. Analysis of the active ingredients showed 0.28 mg/g of procyanidin B3, 12.81 mg/g of rutin, 0.51 mg/g of quercetin, and 8.24 mg/g of kaempferol. After UVB irradiation on the dermis, to confirm the degree of inhibition of collagen synthesis, we examined the protein expression of MMP-9 using immunohistochemical staining. The results of this study confirm the existence of active polyphenol types, such as rutin, kaempferol, quercetin, and procyanidin B3, in GPSE. Moreover, the study found that GPSE has anti-collagenase effects and it decreases the effects of UV damage on skin barrier function. GPSE is a functional ingredient with a potential for skin protection effects, and it has high utilization potential as an ingredient for functional cosmetics.

Compostable household wastes(mainly food residues) were composted in a small bin for 30 days, in which compostable household wastes were fed every day and mixed thoroughly under aerobic conditions. Three small bins were employed. In the first bin only recycled compost was composted, in the second, compostable household wastes with recycled compost, and in the third compostable household wastes with recycled compost and vermiculture. The correct decomposition rate of each composting material was calculated during composting. Total reduced rate of the weight after 30 days was 57.32% when composting the compostable household wastes with recycled compost, and 64.71% when composting them with recycled compost and vermiculite. In the case of composting the compostable household wastes with the recycled compost, the total weight reduction rate for a day was 6.81% and the total decomposition rate 6.81%. Their difference was not great. But in the case calculated with only compostable household wastes the total weight reduction rate was 56.34% and the decomposition 6.79%. When compostable household wastes were composted with the recycled compost and vermiculite, the total weight reduction rate was 64.99% and the decomposition rate 1.48%, but the total weight reduction 4.36% and the decomposition rate 35.46% when calculated with only compostable household wastes. MgO, $K_2O$ and Cr concentrations in the composting mixture during the early composting time were higher when composted with vermiculite than without it, but organic matter, CaO, NaCl, and $P_2O_5$ concentrations were contrarily diluted because of their lower concentration of vermiculite when compostable household wastes were composted with vermiculite.

The purpose of this study was to obtain basic data for using Aronia as a functional food material. The composition of anthocyanin was characterized and quantitated by LC-MS/MS, HPLC, and UV-VIS spectrophotometer techniques, respectively. The anthocyanin content was analyzed by temperature, time, pH, and the addition of citric acid. The UV-VIS spectrophotometer used for analysis of anthocyanin is less accurate than the LC-MS/MS method used in recent years. In the past, cyanidin-3-Glucoside was reported to be a major anthocyanin that contains Aronia. However, LC-MS/MS analysis in this study confirmed cyanidin-3-galactoside to be the major compound. The anthocyanin content of the Aronia powder began to decrease sharply at a temperature of $65^{\circ}C$ or higher when heated for 24 hours. In an aqueous solution of Aronia, the anthocyanin content was reduced by 50% at $65^{\circ}C$ for 10 hours and decreased by 85% at $85^{\circ}C$ within 10 hours. Above pH 8, the anthocyanin content was reduced by more than 50%. The results of this study will provide useful information to maintain anthocyanin content in the manufacturing process of Aronia. It could also be used to ensure the stability of anthocyanins in similar species of berries.

The objective of this study was to determine the effects of various kinds of composts on the change of soil chemical properties in upland soils. Field experiments were conducted in the loam and sandy loam soils. Various kinds of composts such as poultry manure compost(PMC), cow manure compost(CMC), human excrement sludge(HES), and food industrial sludge compost(FISC) were applied annually at rates of 0, 40, and $80Mg\;ha^{-1}$ to soils grown with soybean and maize plants for 4 years during 1994 to 1997. The results of this study were as follows : The continuous application of human excrement sludge decreased soil pH up to 4.4~5.0, while other compost treatments increased soil pH compared with control plot. The EC increased initially and showed their maximum values at 20days after compost application, and then decreased up to 40 days, thereafter kept a certain level. The available phosphorous accumulated at 0~20cm depth in loam soil, and 0~50cm in sandy loam soil. Annual accumulation rates were 17% higher in sandy loam soil than loam soil. The more compost application rates and times, the higher base saturation percentage increased in upland soils. Four year's application at a rate of $80Mg\;ha^{-1}$ per year increased the base saturation percentage to 87~91% compared with 45% at control plot in the loam soil. While in sandy loam soil only three year's application of same rate increased the base saturation percentage to 81~92% compared with 30.4% at control plot. The average annual increasing rate of base saturation percentage at the same application rates of composts were higher in sandy loam soil by 2.0~3.7 times than in loam soil. The application of compost increased the exchangeable Ca, Mg, and K contents of soils by 2, 2~3, and 3~5 times, respectively, compared with the control. The contents of exchangeable canons were high in surface soil. and decreased with increase of soil depths. In the case of heavy metal content, there were no difference at the application of PMC and CMC but Ni. Fe, Zn, Cu was increased a little when the HES applied, and Ni and Cr was increased application with FISC.

This experiment was conducted to select suitable cultivars and evaluate growth characteristics to get basic information for sprouting peanut. On sprouting peanut, it showed a rapid increase in trans-resveratrol content that has effects on anti-cancer, anti-inflammatory, blood-sugar-lowering and other beneficial cardiovascular in mouse. For this experiment, characteristics of peanut sprouts were tested in 37 cultivars grown for 7 days at $26^{\circ}C$ temperature. There were a lots of variations in the growth characteristics among cultivars as followers : The range of 100 grain weight was 56 to 142 g, hypocotyl length was 4.3 cm to 5.8 cm, diameter of hypocotyl was 5.0 to 8.0 mm, epicotyl length was 0.8 cm to 4.6 cm, seedling ratio per seed number was 84% to 100%, weight per seedling was 4.9 g to 8.4 g, the rate of hypocotyl cleavage was 0% to 46%, the content of trans-resveratrol was $22.5\;{\mu}g/g$ to $88.2\;{\mu}g/g$ and sprout yield was 360% to 820%. The selection points considered were high sprout yield, high seedling rate, high resveratrol content, low brownish cotyledon, no hypocotyl cleavage, and fat hypocotyl etc. The best cultivar selected was 'Jokwang' that showed 7.8 mm diameter, clean cotyledon color, 100% seedling rate, 0% hypocotyl cleavage, $63.3\;{\mu}g/g$ resveratrol, and 820% sprouting yield. This cultivar was expected to be of use as a new food and nutraceutical material. Relationship between growth characteristics showed that root length had significant positive correlations with epicotyl length, resveratrol content and sprouting yield but negative correlations with hypocotyl diameter and cleavage. Hundred grain weight showed negative correlations with resveratrol content, seedling rate and sprouting yield but positively correlated with curved hypocotyl rate and hypocotyl cleavage positively. This result showed small grain seed will be more appropriate for sprouting peanut.

This study that had been conducted two months by a research team of Pusan National University at the request of Korea Manwha Contents Agency in Dec. 2013 is about the statistical analysis on 'Korean Webtoon DB and its Flow Report' which resulted from the complete survey of Korean webtoons which had been published with payment in official media from early 2000 to 2013. Webtoon which means the cartoons published on web has become a typical type of Korean cartoons and has developed into a main industry since 2000s when traditional published cartoons had declined and social environments had changed. Today, it represents cultural contents in Korea. This study collected the webtoons officially published in media with payment, among Korean webtoons having been published from the early 2000s to Jan. Based on the collected data, it analyzed the general characteristics of webtoons, including cartoonists, the number of cartoons, distribution chart of each media, genre, and publication cycle. According to the data analysis and statistics, a great deal of Korean webtoons are still published in main portal websites, but their platform is being diversified and a webtoon's publication cycle tends to be shortened. In terms of genre, traditional popular genres, such as drama, comic, fantasy, and action, are still popular, and the genres of history, sports, and food are on the rise along with a social trend. Regarding webtoon application, such events as relay webtoon and brand webtoon, and a new type of webtoon featuring PPL commercialism appear. Such phenomena can realize the common profits of cartoonists, media, and ordering bodies, and are various trials to test the possibility of webtoons. In addition, what needs to pay attention on in the expansion of webtoons is increasing webtoons for adults. The study subjects are the webtoons published with payment, excluding free webtoons. However, this study failed to collect the webtoons published on the online websites already closed, and the lost information on cartoonists and their lost webtoons, and it is necessary to conduct a complete survey on all webtoons including free ones. Despite the limitations, this study is meaningful in the points that it categorized and analyzed Korean webtoons accoridng to official media, webtoons, cartoonists, and genres and that it provided a fundamental material to understand the current conditions of webtoons. It is expected that this study will be able to contribute to activating more research on webtoons and producing more supplementary data which will be used for the Korean cartoon industry and academia.
