Indonesia has the largest economy in Southeast Asia and is one of the fastest growing economies of the world. This study was conducted to understand Indonesian food consumers, and to provide the marketing implications for food exporting companies in Korea. An online survey was conducted on 795 local consumers in Indonesia and the study analyzed their preference for Korean food and Korean culture. Then this study identified the relationship of these variables and consumers’ intention to purchase Korean food. The results of this study were as follows. First, Indonesian consumers had a strong preference for Ramyeon, noodles, snacks and kimchi among Korean foods. Second, the preference for Korean culture was high in a descending order of Korean dramas, cosmetics, songs and news. Third, both Korean food and Korean culture preferences showed significant differences depending on gender, age and the frequency of eating out. Lastly, analysis of the relationships among the variables showed that there is a positive relationship between Korean food preferences and Korean food purchase intentions. Further, the consumers’ Korean culture preference had a mediating effect within this relationship. The results of this study imply that marketers in Korea food companies need to consider the consumers’ preference for Korean food and Korean culture when they build proper strategies for exporting Korean foods to Indonesia.

Agrocybe cylindracea was cultured in a bag, in which sawdust culture medium (1 kg) is put in a plastic bag (PE), with poplar sawdust, rice bran, wheat bran, and dried bean curd refuse in the ratio of 70:10:10:10 (v/v). 2% of the culture medium was inoculated with the liquid starter of Agrocybe cylindracea, and this was incubated at 25oC. After incubation, the A. cylindracea was further cultured by cutting the top vinyl portion of the bag down to the level of the culture medium surface of the first inoculation part. The cut culture medium was placed in a growth room at 25oC, and pin-heading was induced under light irradiation at 99% humidity and 1,000 ppm CO2 level for 3days. When the grow the environment was controlled at 95% humidity and 21oC, the bending of the stem was less as compared to that when the cap of the bag had been removed. The number of effective fruiting bodies per bag increased by 140% (28.8), the quantity per bag increased by 29.5%, and 148.5 g A. cylindracea could be potentially harvested.

This study examined the potential of export items in Malaysia by investigating the awareness and preference for Korean food products. A high potential product list developed from the literature, included reports about the food export status in Korea and Malaysian food trends. An online survey was carried out with 600 consumers in Malaysia. With 435 valid responses, the average awareness of the Korean food products was 3.13, and the preference was 3.48 on a 5-point scale. The awareness and preference of Korean food products were higher in the 20s-30s group than in the older groups. In particular, the Muslim group had a higher awareness for ‘ramyon’ than the other groups, and the Buddhist group had a higher preference for ‘ginseng beverage’ than the other groups. The most well-known and preferred products were ramyon, hot noodles, kimchi, biscuits, fruits & vegetable beverage, and sauce (with Korean traditional sauce)’. Based on these results, the marketing implications of the study findings are discussed.

The age and growth of Pleurogrammus azonus in the coastal of Gangwon-do, East Sea were determined, from monthly samples of commercial catches, caught by the gill net and set net fishery from January to December in 2008. Gonadosomatic index (GSI) began to increase in September, and reached the maximum between November and December. After spawning GSI began to decrease from January. The annuli of P. azonus are formed once a year, with the boundary between opaque and translucent zones forming from December to January. The relationships between fork length (FL) and body weight (BW) were BW = 0.005 FL3.240(R2 = 0.963) for females and BW = 0.006 FL3.238(R2 = 0.946) for males. The FLs at annuli formation in otoliths were back-calculated from the otolith-length relationship and were adjusted to von Bertalanffy growth curves to FLt = 70.54 (1–exp(-0.099(t+1.188))) for females and FLt = 51.87 (1–exp(-0.135(t+1.697))) for males. Until the age of 3 years, males grew faster than females; however, from the age of 4 years, females grew faster than males. In the future, we want to study the relationship between early growth and water temperature changes in the East Sea

급성 췌장염은 다양한 원인에 의해 발생되는 췌장의 염증성 질환으로 담도질환에 대한 내시경 시술이나 영상의학적 시술에 의해서 유발되기도 한다. 담도 시술과 관련하여 발생 하는 췌장염은 담도에 대한 조작보다는 바터팽대부를 절개 또는 확장시키거나 바터팽대부를 통과시켜 스텐트 혹은 도관을 거치하면서 유발되는 췌관의 압박에 의해 발생하는 것으로 알려져 있다. 바터팽대부에 대한 조작을 시행하지 않는 경우에는 췌장염 발생의 위험성이 없는 것으로 되어 있고 더 하여 경피경관담도경 시술을 위한 도관 삽입 후에 췌장염이 발생한 경우는 보고된 바가 없었다. 본 증례에서는 3cm 가량의 거대 총담관 담석들에 의해 발생된 담도염에 대해 경피 경관담도경 시술을 준비하는 과정 중 총담관에 도관을 삽입 한 이후 급성 췌장염이 발생하였다. 이에 저자들은 원위부 총담관 내부에 삽입된 도관으로 인해 거대 총담관 담석이 췌장두부를 압박하였고 이로 인한 주췌관의 가역적인 폐색이 유발되어 급성 췌장염이 발병한 증례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

This present study investigated characteristics of distribution and community structure of macrobenthic invertebrates through the survey of commercial Danish seine fisheries from 2011 to 2013. In this study, a total of 28 species were sampled with a mean density of 32,568 ind./km2 and mean biomass of 1,649.5 kg/km2. The dominant species, comprising over 1.0% of the total number of individuals, were Chionoecetes opilio (11,203 ind./km2, 34.4%), Pandalus eous (9,247 ind./km2, 28.4%), Ophiuridae spp. (5,750 ind./km2, 17.7%), Argis lar (2,631 ind./km2, 8.1%), Neocrangon communis (994 ind./km2, 3.1%), Berryteuthis magister (612 ind./km2, 1.9%), Sepiola birostrata (499 ind./km2, 1.5%) and Strongylocentrotidae sp. (424 ind./km2, 1.3%). The dominant species, in terms of biomass, comprising over 1.0% of the total biomass, were C. opilio (1,167.2 kg/km2, 70.8%), B. magister (130.3 kg/km2, 7.9%), P. eous (102.4 kg/km2, 6.2%), Ophiuridae spp. (84.6 kg/km2, 5.1%), Enteroctopus dofleini (45.5 kg/km2, 2.8%), A. lar (35.7 kg/km2, 2.2%), Strongylocentrotidae sp. (25.0 kg/km2, 1.5%) and S. birostrata (22.1 kg/km2, 1.3%). Among them, S. birostrata, E. dofleini, Strongylocentrotidae sp. and Ophiuridae spp. were higher abundance and biomass in the shallow water (<200 meters in depth), whereas C. opilio, P. eous, A. lar, N. communis and B. magister were higher in the deep water (301 ~ 500 meters in depth).As the results of cluster analysis and non-metric multidimensional scaling (nMDS) analysis based on the Bray-Curtis similarity of fourth root transformed data for number of species and individuals, the macrobenthic invertebrates community by Danish seine survey was divided into two groups of station in the shallow water (<200 meters in depth, Group A) and the deep water (201 ~ 500 meters in depth, Group B). The major individual-dominant species was S. birostrata, Ophiuridae spp. and immature C. opilio in group A. But Group B was P. eous, A. lar, B. magister and mature C. opilio.

For a decade, solution-processed functional materials and various printing technologies have attracted increasingly the significant interest in realizing low-cost flexible electronics. In this study, Cu nanoparticles are synthesized via the chemical reduction of Cu ions under inert atmosphere. To prevent interparticle agglomeration and surface oxidation, oleic acid is incorporated as a surface capping molecule and hydrazine is used as a reducing agent. To endow water-compatibility, the surface of synthesized Cu nanoparticles is modified by a mixture of carboxyl-terminated anionic polyelectrolyte and polyoxylethylene oleylamine ether. For reducing the surface tension and the evaporation rate of aqueous Cu nanoparticle inks, the solvent composition of Cu nanoparticle ink is designed as DI water:2-methoxy ethanol:glycerol:ethylene glycol = 50:20:5:25 wt%. The effects of poly(styrene-co-maleic acid) as an adhesion promoter(AP) on rheology of aqueous Cu nanoparticle inks and adhesion of Cu pattern printed on polyimid films are investigated. The 40 wt% aqueous Cu nanoparticle inks with 0.5 wt% of Poly(styrene-co-maleic acid) show the “Newtonian flow” and has a low viscosity under 10 mPa·S, which is applicable to inkjet printing. The Cu patterns with a linewidth of 50~60 μm are successfully fabricated. With the addition of Poly(styrene-co-maleic acid), the adhesion of printed Cu patterns on polyimid films is superior to those of patterns prepared from Poly(styrene-comaleic acid)-free inks. The resistivities of Cu films are measured to be 10~15 μΩ·cm at annealing temperature of 300 ˚C.

It was turned out by the beam trawl survey in 2009 that flora of three phylum 16 species and fauna of eight taxa 68 families 97 species were inhabited in the Seomjin River estuary and western coastal waters of Namhae island. Winter season showed the most various appearance of species with 63 species and markedly several kinds of algae species, while summer season showed the lowest number of species with 44 species. However, the indices of species diversity and evenness were highest in summer, and vice versa in winter. Major dominant species were Crangon hakodatei, Leiognathus nuchalis, Asterias amurensis, Thryssa kammalensis, Luidia quinaria, Amblychaeturichthys hexanema, Oratosquilla oratoria, Charybdis bimaculata, Cynoglossus joyneri, Pennahia agentata. The 10 dominant species occupied at 81.4% of catch in number and 49.0% of catch in weight. There were seasonal fluctuations and differences by station in the Seomjin River estuary and western coastal waters of Namhae island, which brought to the difference of length structures, that is, bigger-sized individuals of major dominant species at station A (near to river estuary) than station C (near to ocean). Species compositions by season and by station were separated to two groups. Winter season showed a separated species composition from other seasons and station A exhibited a different species composition from other stations, which was located at near to the Seomjin River estuary.
