In 2007, due to the outcome of the Korea-U.S. FTA negotiations, the opportunities for American beef greatly increased and a serious change in the domestic dining market is expected. The market currently faces issues such as the settlement of the beef origin declaration policy and the fulfillment of customer needs on domestic and imported beef. The following are the summary of the results of the aforementioned research and analysis. First, the consumer awareness level of origin declarations was comparatively low. Second, the reason behind the propensity for imported beef was the comparatively cheaper price despite the lower taste quality, and it was determined that there is a high level of distrust on domestic beef sold in general restaurants. Third, domestic beef showed a high valuation in taste, safety and freshness, while imported beef showed results which were below average. Concluding from the above research results, a dining environment should be created where consumers can trust what they eat through settlement of an origin declaration policy, and more efforts should be put into fulfilling consumer needs for both domestic and imported beef.

Glioblastoma (GBM) is the most common and aggressive form of human adult brain malignancy. The identification of the cell of origin harboring cancer-driver mutations is the fundamental issue for understanding the nature of GBM and developing the effective therapeutic target. It has been a long-term hypothesis that neural stem cells in the subventricular zone (SVZ) might be the origin-of-cells in human glioblastoma since they are known to have life-long proliferative activity and acquire somatic mutations. However, the cell of origin for GBM remains controversial due to lack of direct evidence thereof in human GBM. Our recent study using various sequencing techniques in triple matched samples such as tumor-free SVZ, tumor, and normal tissues from human patients identified the clonal relationship of driver mutations between GBM and tumor-free SVZ harboring neural stem cells (NSCs). Tumor-free SVZ tissue away from the tumor contained low-level GBM driver mutations (as low as 1% allelic frequency) that were found in the dominant clones in its matching tumors. Moreover, via single-cell sequencing and microdissection, it was discovered that astrocyte-like NSCs accumulating driver mutations evolved into GBM with clonal expansion. Furthermore, mutagenesis of cancer-driving genes of NSCs in mice leads to migration of mutant cells from SVZ to distant brain and development of high-grade glioma through the aberrant growth of oligodendrocyte precursor lineage. Altogether, the present study provides the first direct evidence that NSCs in human SVZ is the cell of origin that develops the driver mutations of GBM.

Purpose: The aim of this study was to assess the clinical characteristics of hypertensive encephalopathy according to the underlying etiologies in children. Methods: We retrospectively evaluated 33 pediatric patients who were diagnosed as having hypertensive encephalopathy in Chonbuk National University Children's Hospital. Among the patients, 18 were excluded because of incomplete data or because brain magnetic resonance imaging (MRI) was not performed. Finally, 17 patients were enrolled and divided into a renal-origin hypertension group and a non-renal-origin hypertension group according to the underlying cause. We compared the clinical features and brain MRI findings between the 2 groups. Results: The renal group included renal artery stenosis (4), acute poststreptococcal glomerulonephritis (2), lupus nephritis (2), and acute renal failure (1); the nonrenal group included essential hypertension (4), pheochromocytoma (2), thyrotoxicosis (1), and acute promyelocytic leukemia (1). The mean systolic blood pressure of the renal group ($172.5{\pm}36.9mmHg$) was higher than that of the nonrenal group ($137.1{\pm}11.1mmHg$, P<0.05). Seizure was the most common neurologic symptom, especially in the renal group (P<0.05). Posterior reversible encephalopathy syndrome (PRES), which is the most typical finding of hypertensive encephalopathy, was found predominantly in the renal group as compared with the nonrenal group (66.6% vs. 12.5%, P<0.05). Conclusion: We conclude that the patients with renal-origin hypertension had a more severe clinical course than those with non-renal-origin hypertension. Furthermore, the renal-origin group was highly associated with PRES on brain MRI.

Acetes chinensis is an economically important shrimp that belongs to the Sergestidae family; following fermentation, A. chinensis' economic value, however, is low in China, and much of the catch in China is exported to Korea at a low price, thus leading to potential false labeling. For this reason, we developed a simple method to identify A. chinensis' origin using allele-specific polymerase chain reaction (PCR). Ten single nucleotide polymorphisms (SNPs) were identified from partial (i.e., 570 bp) DNA sequence analysis of the mitochondrial 16s rRNA gene in 96 Korean and 96 Chinese individual shrimp. Among 10 SNP sites, four sites were observed in populations from both countries, and two sites located in the middle with SNP sites at their 3'-ends were used to design allele-specific primers. Among the eight internal primers, the C220F primer specific to the Chinese A. chinensis population amplified a DNA fragment of 364 bp only from that population. We were able to identify the A. chinensis population origin with 100% accuracy using multiplex PCR performed with two external primers and C220F primers. These results show that the 16S rRNA gene that is generally used for the identification of species can be used for the identification of the origin within species of A. chinensis, which is an important finding for the fair trade of the species between Korea and China.

The Korea Foreign Trade Act(KFTA) was revised the penal provisions of the breach of the Country of Origin Labeling(COOL) recently. The ceiling of penalties became to 5 years for imprisonment, one hundred or three hundred million won for fine. The level of penalties are adjudged quite fair but the amount of penalty should be increased according to the profits from the breach or the nature of crime in some cases. The problems of the penalties are differences between KFTA and other related laws. There are related several laws on the breach of the COOL such as KFTA, Unfair Trade related Law, Customs Law, Consumer Protection Law, Law of COOL on Agricultural and Marine products etc. The penal provisions of the breach of the COOL has more heavier level than other the breach because of the criminal qualities. The problems are the penalty differences between the KFTA and the Unfair Trade Law under the Ministry of Knowledge Economy. The KFTA's penal provisions need to equate with Unfair Trade Law as long as same breaches on the COOL. The government can also consider some policies to rigid enforcement of breaches on the COOL. There are the Country of Origin Tracking system, the RoO Paparazzi System, Make public the names of habitual RoO Violators, Correction Order of breach of the COOL etc.

The purpose of this study was to investigate and verify interaction effects of collaboration and brand origin as well as fashion involvement on consumer attitudes towards global sports apparel brands and Chinese local sports apparel brands targeting Chinese consumers. A survey was conducted on 425 Chinese women aged 19 to 34 years. Data were subjected to frequency analysis, reliability analysis, t-tests, 3-way ANOVA, and simple effect analysis. Results of the study are as follows. First, fashion involvement, collaboration, and brand country of origin all had a significant effect on consumer preference of Chinese consumers when purchasing sportswear. Second, fashion involvement and collaboration in purchasing sportswear had a significant interaction effect on consumer preference. Finally, collaboration, brand origin, and fashion involvement showed significant three-way interaction effects on Chinese consumers' preferences. Results of this study can help establish an efficient marketing strategy for Chinese local sportswear brands, which are fiercely competing with global sportswear brands in the Chinese market because they can examine Chinese consumers' attitudes toward sportswear brands. To accurately compare global and local sportswear brands, it must be assumed that there are no differences in brand preferences among consumers. However, as this study selected each brand as the research brand ranked as the top preference, this aspect was not taken into consideration. Therefore, in future research, it is necessary to consider differences in brand preferences and conduct the study accordingly.

The purpose of this study was to examine whether corporate sports marketing strategy using professional teams changes corporate image. In particular, this study was intended to analyze the effects of origin and corporate reputation on the change of corporate image in the process of persuading corporate image. Finally 211 effect data were secured by pre-test and post-test. The change of corporate image and the moderating effect of origin perception and corporate reputation were analyzed. The results were as follows. First, corporate trust image and social contribution image showed statistically significant increase. Second, corporate image had a difference before and after the test according to origin perception and after the test, corporate trust image and social contribution image were increased. Third, corporate image had a difference before and after the test according to corporate reputation. After the test, corporate trust image and social contribution image were increased and trust image confirmed the mediating effect according to corporate reputation. Based on the findings, this study suggests that corporate sports marketing strategy using professional teams has an effect on the persuasion of corporate image. Moreover, it demonstrates that the strategy is an important marketing tool to change consumers' corporate image.
