Purpose - The aims of this study are follows. We investigated to find out how country image and brand image affect the consumer perceived value, consumer attitude, and purchase intention of foreign infant foods in China. Especially, we focused on investigate for the moderating role of consumer knowledge between national image, brand image and consumer perceived value of foreign infant foods in China. Research design, data, and methodology - This study analyzed the effect of national image and brand image on purchase intention through consumer perceived value and consumer attitude. This study collected data for empirical analysis of Chinese consumers who have been purchase experience infant foods in China. 256 copies of questionnaire data were used for substantial analysis. Before testing the hypothesis, factor analysis was conducted to test the construct validity of measurement items. Hypotheses about effects between variables were verified using structural equation modeling analysis and hierarchical regression analysis. Results - First, the country image had a positive effect on consumer perceived value of foreign infant foods. Second, the brand image had a positive effect on consumer perceived value of foreign infant foods. Third, the consumer perceived value had a positive effect on consumer attitude. Fourth, the consumer attitude had a positive effect on purchase intention. Fifth, the consumer knowledge was moderating roles between brand image and consumer perceived value of foreign infant foods. However, the consumer knowledge did not effect of moderating between country image and perceived value of consumers. Conclusions - First, the impact of country image and brand image on consumer perceived value of foreign infant foods in China can be seen as a universal psychology of consumers who trust pure foreign products such as high quality, technology, etc. Second, consumer perceived value of foreign infant foods has a positive effect on consumer attitude, and this attitude is leading to purchase intention. Third, the consumer knowledge between brand image and perceived value acts as a moderating variable. It means that the consumer's knowledge can shape the perception of the brand image more strongly.

복합말뚝(Composite Pile)이란, 수평력이 크게 작용하는 구간에는 강관말뚝, 작게 작용하는 구간에는 PHC말뚝을 특수한 연결 장치로 결합한 말뚝으로서 토목 구조물의 기초 재료로써 상용화되는 추세에 있다. 이러한 복합말뚝의 핵심은 강관말뚝과 PHC말뚝을 연결하는 연결 장치의 안정성과, 이음 위치를 산정하는 설계기준이라고 할 수 있는데 국내에서는 복합말뚝 이음부 위치에 대한 정확한 시방규정이 없어서, LH 설계처(한국토지주택공사, 2009)에서는 도로설계요령 제3권(한국도로공사, 2001)을 참고하여 작성한 "복합말뚝 설계적용 및 설계도서 표기 방안 검토"를 복합말뚝 설계의 기준으로 사용해 오고 있지만 복합말뚝의 단면변화라고 볼 수 없어 적용에 한계성을 가지고 있는 실정이다. 이에 따라 본 연구에서는 복합말뚝의 단면 변화부(강관말뚝과 PHC말뚝의 이음부) 위치에 대한 설계기준을 제안하고 이에 대한 안정성 및 경제성을 검토하고자 실험적인 방법과 해석적인 방법을 이용하여 연결장치에 대한 안정성을 검증하였으며, 국내 교량공사 교대 79개소에 시공된 복합말뚝 설계자료를 분석하여 말뚝 본체 및 이음부에 작용하는 응력, 휨모멘트, 변위 등의 경향성을 파악하였고, 개선식이 적용된 재설계 과정을 통해 이음부에서 발생한 응력들이 연결장치와 PHC말뚝의 허용응력 수치 내로 발생하는 것을 확인하였다. 결론적으로 사례분석을 통한 복합말뚝 이음위치의 설계 제안식은 복합말뚝을 설계함에 있어서 안정성과 경제성을 모두 고려한 개선된 설계기법임을 알 수 있었다.

The purpose of this study was to examine the correlation between Juvenile alcohol use and their criminal patterns. The data were collected through questionnaire surveys. Subjects serving for this study were 971 delinquent adolescents in Korea, sampled from 6 juvenile corrective institutions and 2 classification judging institutions, using a census method. Their age range was between 12 and 21. Data were analysed by IBM PC using SAS program. Statistical methods employed were Chi-square and frequency analysis. 1. Of 877 respondents, the number of adolescents committed criminal behaviors while the intoxicated were 230(26.2%), and 647(73.8%) were in a non-intoxicated state. 2. Adolescent under intoxication showed a higher rate of aggressive crimes and assault crimes, whereas adolescents under the non-influence of liquor tended to commit property climes and violations of criminal special law Drunken state adolescents during committing criminal behaviors used knifes, stones or fist-kicking as criminal tools, whereas drug use or without weapons in non drunken state. Most crimes have happened without any tools in both group. 3. In comparison of the alcohol user and the non-user, most alcohol-related crimes among adolescents were committed at AM 0:00 to AM 4:00 during the weekend in the dark, cloudy, and stormy-rainy day, while non-alcohol related crimes were at afternoon of weekday in the clear day. The places that the criminal activities occurred were streets, amusement places such as disco-theque, fields and their own house among alcohol users, whereas victim's house, another person's house and restaurant were chosen among non-alcohol users. 4. The victims assaulted by Juvenile offenders in both drunken and non-drunken state were mostly passer-by(65.4%), followed by their friends(25.1%). And the conditions of victims showed a significant differences between the drunken adolescents and the non-drunken adolescents. The victim's conditions assaulted by intoxicated delinquent adolescents were in quarreling or drunken state, whereas non-alcohol related crimes were directed against victims in a sleeping or irresistible state. 5. Almost over the half of delinquent adolescents perceived their delinquency as wrong behaviors. and alcohol non-user tended to more significantly perceive their criminal acts as wrong conducts. About the half of respondents answered that they committed their criminal acts in spite of having a very good Judgement while doing crimes, the author did not found a significant difference between the two groups. The reasons given for crimes were manifested as follows: it can be seen that ‘to get money for amusements’(30.4 % of all motives) were most common, followed by ‘to commit accidentally the offences’(23.8%), ‘curiosity or heroism’(18.9%). alcohol related crimes tended to be accidental and impulsively without any clear planning, while non-alcohol related crimes tended to be purposeful, directed to make money motivated by curiosity or a desire to live heroically. In Conclusions. the correlation between alcohol use and Juvenile criminal behaviors has been examined in this study. Generally, alcohol use had been found to be highly correlated with aggressive assault crimes including robbery, burglary and rape etc.

In terms of environmental friendly land use and objective environmental assessment, legislative assessment items of Environmental Conservation Value Assessment Map (ECVAM) consists of designated areas related to conservation and protection, and areas that are planned to be designated in the future. However, the gap with the reality due to omission of several protection areas and land use regulations, and assessment grades according to 3 division land use map of forest, agricultural land, and urbanized area, results in low application and utilization of ECVAM. Therefore in this study, the legislative assessment of the ECVAM was performed with new assessment items and its new ratings, to suggest an improvement in legislative assessment items of the ECVAM. As a result, legally protected areas of inhabited islands under absolute conservation, special wildlife protection districts, protected marine areas, environmental preservation sea areas, scenic spots, forest protection zone, traditional temple preservation zone, and 45 zone or district related to regulation of land use were additionally designated as new legislative assessment items. New grade ratings were given to each additional assessment items in consideration of the restrictions on acts. As a result of the legislative assessment based on the new assessment items and new grades, the 1st grade area increased by 3.47%, and the 2nd grade area increased by 19.35%. The 3rd grade area decreased by 8.54%, the 4th grade area increased by 2.95%, and 5th grade increased by 2.91%. In addition, the out-of-grade area decreased by 20.14%, considered to be a realistic assessment based on land use. With the improved legislative assessment, it is possible to provide a more accurate environmental assessment map. Increase usage of ECVAM is expected in providing regulations of land use and base data for integrated land management of land environmental planning.

Glutathione peroxidase 3 (GPx3), an antioxidant enzyme, acts as a modulator of redox signaling, has immunomodulatory function, and catalyzes the detoxification of reactive oxygen species (ROS). GPx3 has been identified as a tumor suppressor in many cancers. Although hyper-methylation of the GPx3 promoter has been shown to down-regulate its expression, other mechanisms by which GPx3 expression is regulated have not been reported. The aim of this study was to further elucidate the mechanisms of GPx3 regulation. GPx3 gene analysis predicted the presence of ten glucocorticoid response elements (GREs) on the GPx3 gene. This result prompted us to investigate whether GPx3 expression is regulated by the glucocorticoid receptor (GR), which is implicated in tumor response to chemotherapy. The corticosteroid dexamethasone (Dex) was used to examine the possible relationship between GR and GPx3 expression. Dex significantly induced GPx3 expression in H1299, H1650, and H1975 cell lines, which exhibit low levels of GPx3 expression under normal conditions. The results of EMSA and ChIP-PCR suggest that GR binds directly to GRE 6 and 7, both of which are located near the GPx3 promoter. Assessment of GPx3 transcription efficiency using a luciferase reporter system showed that blocking formation of the GR-GRE complexes reduced luciferase activity by 7-8-fold. Suppression of GR expression by siRNA transfection also induced down-regulation of GPx3. These data indicate that GPx3 expression can be regulated independently via epigenetic or GR-mediated mechanisms in lung cancer cells, and suggest that GPx3 could potentiate glucocorticoid (GC)-mediated anti-infla-mmatory signaling in lung cancer cells.

Pim kinase-3(Pim-3), a member of serine/threonine protein kinases, has been implicated in multiple human cancers and involved in Myc-induced tumorigenesis. However, little is known regarding its expression and biological function in human ovarian cancer. In this study we showed that the clinical significance and biological functions of Pim-3 in ovarian cancer and found that higher Pim-3 mRNA level are detected in ovarian cancer tissues than those in normal ovarian tissues. There are significant correlations between higher Pim-3 expression levels with the FIGO stage, histopathological subtypes, and distant metastasis in ovarian cancer patients. Lentivirus-mediated gene overexpression of Pim-3 significantly promotes the proliferation and migration of SKOV3 cell lines. Furthermore, MACC1 and Pim-3 expression were significantly correlated in human ovarian cancer cells, and overexpression of Pim-3 in ovary cancer cells increased MACC1 mRNA and protein expression. The data indicate that Pim-3 acts as a putative oncogene in ovary cancer and could be a viable diagnostic and therapeutic target for ovarian cancer.

The electrical transport properties of mayenite ($Ca_{12}Al_{14}O_{33}$ or $12CaO{\cdot}7Al_2O_3$; mostly abbreviated as $C_{12}A_7$) can be controlled in a wide range by varying the oxygen deficiency: At high temperatures mayenite becomes either an oxygen solid electrolyte, a mixed ionic/electronic conductor or an inorganic electride with metal-like properties upon chemical reduction (removing oxygen). The underlying defect chemistry can be understood on the basis of a relatively simple model-despite the complex cage structure: A point defect model based on the assumption that the framework $[Ca_{12}Al_{14}O_{32}]^{2+}$ acts as a pseudo-donor describes well the high temperature transport properties. It accounts for the observed conductivity plateau at higher oxygen activities and also describes the experimentally observed oxygen activity dependence of the electronic conductivity with -1/4 slope at temperatures between 800 and $1000^{\circ}C$. Doping effects in mayenite are still not well explored, and we review briefly the existing data on doping by different elements. Hydration of mayenite plays a crucial role, as Mayenite is hygroscopic, which may be a major obstacle for technical applications.
