In this study, it is purpose that value-added-logistics strategy plan for cooperation and coexistence in northeast asia.. Because of the change of domestic industrial structure, Japan's super hub port plan, Yangshan Deepwater port open of china and domestic port logistics industries are faced with competition among northeast asia countries. Decreasing export volume of changed domestic industrial structure and two countries: japan, china, make a new port policy and build new ports will affect domestic port logistics industries because these industries depend on container throughput at Busan port. Now, we cannot get a lot of profit from container throughput more than before and in the future China has more ports most ships direct calling in china's port to handle china's cargo volume to get more profit at that time our plans to become a hub port in northeast need revision. Finally, we need a new strategy which is value-added-logistics strategy. But it considers cooperation and coexistence among northeast countries. So this paper suggests that value-added-logistics strategy plan for cooperation and coexistence to live in affluence together in the future.

In this study, we investigated effect of washing with brine on quality characteristics of strawberries during storage at 4 or $20^{\circ}C$. The strawberry samples were prepared with brine-washing (BW), brine-washing and removing moisture on surface (BWR), or without brine-washing and removing moisture (control). The samples were tested for total aerobic bacteria, pH, color, firmness. BWR affected the microbial change, resulting in retarding the growth of total aerobic bacteria, compared with the control and BW. The initial microbial and exponential growth phase of BWR at $4^{\circ}C$ was not detected. For pH, there wasn't dramatical change on BWR at $4^{\circ}C$ and $20^{\circ}C$. In addition, there was dramatically in decreased on control and BW. A-value was increased over storage time on control and BWR except BW. For firmness, there wasn't dramatical change on all sample when stored at $4^{\circ}C$. The results suggest that storage of strawberry stored after washing and moisture removal from the surface should be applied to maintain quality and shelf-life during storage of strawberries.

This study analyzed the expected economic effects of the Korea-GCC FTA and sought strategies for industrial cooperation. To see the economic effects of Korea-GCC FTA, we analysed the effect of the oil tariff reduction of economy by Vector Autoregression(VAR) model. The estimation results shows that following the abolishment of the tariff on crude oil imports, GDP, GNI and consumption are expected to grow by 0.212%, 0.389% and 0.238%, respectively. Meanwhile, investment, export and import are estimated to drop by 0.462%, 0.413% and 0.342%, respectively. As for prices, producer prices are to rise by 6.356%p, whereas consumer prices fall by 2.996%p. In short, the Korea-GCC FTA and resultant abolishment of the tariff on crude oil imports followed by the decline in crude oil prices will result in declining prices whilst macroeconomic indices, such as GDP, GNI and consumption, will increase exerting positive effects on domestic economic growth. Also, it is necessary to proactively respond to GCC member states' industrial diversification policies for FTA-based industrial cooperation to diversify the sources of crude oil and natural gas imports for further resource risk management.

Today, the world is experiencing a variety of natural disasters due to the extreme weather. Drought that occurred throughout Southeast Asia from February to May 2016 is also a form of abnormal climate. As a result of this drought, five countries, including Cambodia, Thailand, Vietnam, Laos and Myanmar, faced food shortages, food shortages, as well as rice yields for export. In this study, remote sensing technique was applied to the vicinity of Tonlé Sap, the largest lake in Southeast Asia, to quantitatively analyze the damage caused by drought. As a result, the change of land cover caused a drastic decrease in the water system (132.582㎢) and greenery (706.937㎢) in February 2016, and the reduced water system and greenery changed to dry land and paddy field. It was also found that the temperature rise of 6℃ ~ 8 ℃ compared to the previous year due to the drought from February to April 2016 due to the change of the surface temperature. And it was found that the function of the lake was deteriorated in April due to continuous drought.

The quality and sensory characteristics of kimchi during fermentation at 15 $^{\circ}C$ were evaluated. Kimchi was prepared with Chineses cabbage which was brined in 10% salt water added dill hot-water extracts(DK) and stevia hot-water extracts(SK) respectively. The pHs and reducing sugar contents of kimchi were decreased with increasing the fermentation time whereas lactic acid(%) was increased. The pH of DK was lower than control, and the lactic acid(%) contents of DK, SK were equal or higher than control in the first stage of fermentation. Also, the reducing sugar contents of DK, SK were lower than control. These results showed that the fermentation of DK and SK were faster than that of control in the first stage of fermentation. But the lactic acid(%) contents of DK, SK were higher than control after the 12th day of fermentation. It showed that it is possible to extend the preservation of kimchi. With increasing fermentation time, the L value of kimchi juice was increased, and the a value was decreased, and the b value was constant. Especially, the a value of DK, SK was higher than control. It meant that DK, SK kept more carotenoids in kimchi than control. On the 6th day of fermentation, the sensory evaluation analyzed by ANOVA followed Duncan's multiple range test showed that the levels of the green smell and the moldy flavor of DK were significantly lower than control(p<0.05) and the levels of the green smell, the green flavor and the moldy smell of SK were significantly lower than control(p<0.05), too. And the level of overall flavor of DK, SK was higher than control. The most preference among experimental groups was SK and then control, DK. The levels of TBARS of DK, SK were generally lower than control, and the level of TBARS of DK was lower than SK.

A study was conducted to examine the effect of maturity and precooling ($60%/0^{\circ}C$ and $80%/4^{\circ}C$), and light illumination on the storage life of 'Maehyang' strawberry meant for export. Fruits at 60% and 80% ripened stage were harvested from a commercial greenhouse in Jinju on April 3, 2012. Harvested fruits were transported to the precooling system within 30 minutes. Transported fruits were precooled the $4^{\circ}C$ for 2 hours and $0^{\circ}C$ for 5 hours by a forced draft cooling system, and then stored at $6^{\circ}C$. During the storage, the fruits were examined for their changes in hardness, soluble solid content, quality grade, acidity, Hunter value, weight loss, and the incidence of gray mold (Botrytis cinerea) at an interval of two days from April 5 to April 17. Hardness was decreased until 7th days and it was changed to increase at 9th days. Treatment of 60% maturity, $0^{\circ}C$ precooling and no light illumination of strawberry were shown the highest value in freshness. The soluble solid content harvested in 80% maturity strawberry was higher than 60% maturity strawberry until the third day. Quality grade decreased rapidly in 80% maturity stage with light illumination strawberry in comparison to the 60% maturity stage of strawberry. Hunter value 'L' and 'a' showed a rapid change in 60% maturity stage of strawberry. Weight loss decreased rapidly in 80% maturity, $0^{\circ}C$ precooling, and no light illumination of strawberry treatments. Gray mold incidence was found the most at 60% maturity, $4^{\circ}C$ precooling, and light illumination of strawberry. The results from our study indicate that effectiveness for keeping the freshness of strawberry was best achieved by harvesting in low maturity, precooling at $0^{\circ}C$, and with no light illumination.

The maize production in South-eastern Asian countries showed a continuous increase with increasing poultry-livestock from the beginning of the 1990s to early 2010. Also the need for a new variety development of each contries was increased rapidly in the same period. Single-Cross hybrid varieties have been developed and supplied from 2001 instead of multi-cross maize varieties since 1992 in Indonesia. In Cambodia, CP group is mainly manufacturing feeds with most of the forage maize from farmers who are growing its seeds from the company. Cambodian main cultivars are varieties of multinational corporations such as DK8868 from Monsanto, NK6326, NK7328 from Syngenta and CP333 from CP group including local business company. Vietnam is the main maze importing country in South-Eastern Asia which had imported 13 times scale of amount compared to exports in average from 1990 to 2011. Vietnamese government has developed a range of varieties for improving their efficiency in production, such as the LVN-10 with political investments. Their production has been reached to 80% of the total. According to the 2012 MIFAFF (Ministry for Food, Agriculture, Forestry and Fisheries) data in Korea, domestic edible maize cultivation area was approximately 15,000ha. It showed 74,399 tons of production, 3.8% of food self-sufficiency in maize and around 0.9% of grain self-sufficiency rate. The consumption of grain is mostly rely on imports in Korea. To overcome the limit of the domestic seed market and increase maize self-sufficiency, the need to develop maze varieties for world-class is increasing at present through analyzing the market trend and prospect of the seed industry in South-eastern Asia.

Domestic dairy industry is now standing at the crossroad for planning next fifty years, mainly because economic and environmental situations surrounding Korean peninsula are fast changing. For the aspects of dairy consumption, fresh milk consumed less, while consumption of the other milk and dairy products is slightly increasing every year. In 2010, it is approximately estimated that 1,939,000 tons of raw milk was used and the supply would be short by about 35,000 tons, based on the amounts in the previous year. Currently, multilateral negotiations against US and EU are underway. When it will be in effect in the future, significant damage would be expected in the dairy and livestock sectors, leading to cut domestic milk supply. Quality of farm-gate milk is graded as 1A on average 90% or more, loaded with very low in microbial and somatic cell counts. Therefore, policy implications have to be placed toward switch currently the UHT processing method to Pasteurization or the LTLT technology, by which natural flavors and nutrients in milk mostly remain after heat treatment. Domestic cheese products comprise only 10% and the rest is occupied by the various kinds of imported natural products. The market size keeps increasing up to 65,423,000 tons last year. When it comes to vitalization of our natural cheese industry, cheese whey, which is a main by-product in cheese manufacture, is a critical issue to be solved and also "On-Farm Processing" would be combined with a growth of big dairy companies when few immediate issues among the relevant regulations will be eased and alleviated in the near future. Fermented milk market is recorded as a single area of gradual increase in the past 10 years, Korea. Fermented yogurts with health claims targeted stomach, liver, and intestine are popular and has grown fast in sales amounts. In this context, researches on beneficial probiotic lactic acid bacteria are one of the important projects for domestic milk and dairy industries. Labelling regulations on efficacy or health-promoting effects of functional dairy products, which is the most important issue facing domestic dairy processors, should be urgently examined toward commercial expression of the functionality by lawful means. Colostrum, a nutrition-rich yellowish fluid, is roaded with immune, growth and tissue repair factors. Bovine colostrum, a raw material for immune milk preparations and infant formula, can be used to treat or prevent infections of the gastrointestinal tract. Nanotechnology can be applied to develop new milk and dairy products such as micro-encapsulated lactase milk for consumers suffering lactose intolerance. Raw milk is suggested to be managed by its usage in the processing line because imbalance of supply and demand is structural problem in every country and thus the usage systems as in the advanced dairy countries is worth of bench-marking to stabilize milk supply and demand. Raw milk produced is desirable to divide into the three parts; domestic, import, and buffering purposes. It is strongly recommended that a domestic dairy control center as an institutional framework should be urgently established as is Dairy Board in New Zealand and Australia. Lastly, government policy should be directed to foster the highly-educated people who are majoring in Dairy Sciences or working in the dairy industry by means of financial support in studying and training abroad as well.

The aim of this study was investigated long distance export condition of paprika from Korea to Canada, and evaluated the effect of non-perforated breathable films on the storability of paprika during MA storage in the simulated long distance export condition. The long distance export condition of paprika from Korea to Canada was $7{\pm}1^{\circ}C$ and RH 90% during shipping for 20 days, and then the temperature of that was increased to $13^{\circ}C$ for 3 hours during transferring from refrigerated container to storage room in Canada, and decreased $3{\sim}4^{\circ}C$ for 3 days before distributing to local markets. The temperature and relative humidity of local markets was $16^{\circ}C$ and 60%, respectively. The packing material treatments were non-packing, as control, perforated film (6 mm diameter hole, $18holes/m^2$), and 3 kind of laser treated non-perforated films (oxygen transmission rate was 5,000, 20,000 and 100,000 $cc/m^2{\cdot}day{\cdot}atm$). Under the simulated long distance export condition; $7^{\circ}C$ and RH 90% for 15 days and then $20^{\circ}C$ and RH 55% for 7 days, the fresh weight loss of paprika was less than 1% in 3 kind of laser treated non-perforated film treatments but was more than 4% in control and perforated film treatment that showed severe deterioration of visual quality after 20 days of storage. The atmosphere of paprika packages was changed 5% oxygen and 15% carbon dioxide in 5,000 $cc/m^2{\cdot}day{\cdot}atm$ treatment, and 16% oxygen and 4~5% carbon dioxide in 20,000 $cc/m^2{\cdot}day{\cdot}atm$ treatment during room temperature storage after cold storage for 15 days. A carbon dioxide concentration of these 2 treatments was exceeded the optimal MA and CA condition. There was no significant difference in ethylene concentration among 3 kind of laser treated non-perforated film treatments. A paprika packed with 100,000 $cc/m^2{\cdot}day{\cdot}atm$ non-perforated film showed the highest visual quality under the simulated long distance export condition. However, the firmness and soluble solids did not show any significant difference among 3 kind of laser treated non-perforated film treatments. Therefore, we may suggest that 100,000 $cc/m^2{\cdot}day{\cdot}atm$ laser treated non-perforated film was the proper film for MAP of paprika under long distance export condition that was $7{\pm}1^{\circ}C$ and RH 90% for 15 days, and then $20^{\circ}C$ and RH 55% for 7 days.

This study was conducted in order to obtain the informatin of the histochemical changes in each of 6 segments of the epididymal ducts in 32 Korean native male goats. The male goats were examined, dividing into 7 groups, at 4 잔 intervlas from 8 to 32 wks of age. The reuslts obtained were as follows: 1. PAS reaction showed positive on the basal and upper part beyond the nucleus of the peithelium of effernt ductules throughout all the classes of age. It was also positive on the free border and basal and upper part beyond the nucleus of the caput, on the free border andbasal parts of the corpus, and on the basal part of the cauda of the epididymal epithelium. 2. Acid phosphatase reaction was negative on the every part of epididymal epithelium at the age of 8 weeks, however, with the aging it became strangly positive on the areas between the free border and the nucleus, and moderately positive on the basal part of epithelium of the caput and corpus. In the free border adn basal part of the cauda, it was slightly positive. alkaline phosphatase reactin was negative on the every part of epididymal epithelium until 12 weeks of age. From 16 weeks, free border of epididymal epithelium becaqme slightly positive, and from 20 weeks, the reaction became stronger on the basal part but weekend on the free border with the aging. 3. In the sudan black B staining, many blue black granules between the free border and the nucleus, some granules on the basal part, and a few granules on the cytoplasm around the nucleus of the epididymal epithelium were observed from 8 weeks of age as early, and the granules were increased in number with the aging. 4. In Azan staining, reddish violet granules below the nucleus and blue granules on the upper part beyond the nucleus in some cells of epithelia of efferent ductules were noted at 12th and 16th week, and after 24th week, the granules were decreased with the aging. Golgi apparatus were clearly observable on the upper part beyond the nucleus of all parts of epididymal epithelium from 8th week, and also number of intracytoplasmic vacuoles(smaller ones on the upper part and larger ones on the basal part beyond the nucleus) and fine granules were increased with the aging. 5. In the toluidin blue staining, reddish purple granules on the basal part of the epithelium in all the parts of epididymal ducts, particularly brilliant in the cauda, were observed from 8th week as early. 6. In the Cowdry staining, numerous mitochondria, according to aging, were observed between the free border of epithelium and the upper part beyond the nucleus particularly in the catus and corpus of the epididymal ducts.
