Offshore wind power is a representative renewable energy source and a rapidly growing industry. In Gyeongsangnam-do, offshore wind farms of 461.9MW are being pushed for in the Yokji island and are expected to expand further to over 1GW in the future. Accordingly, ports supporting the storage, assembly, transportation, and installation of offshore wind power equipment are expected to play an important role in the smooth progress of the offshore wind farm development project. Based on previous research and cases in major countries,this study prepared criteria for assessment of ports supporting offshore wind farmsand evaluated ports in Gyeongsangnam-do, which are linked to Yokji island offshore wind farms. The assessment criteria have been subdivided into distance from the offshore wind farm, port entry and exit restrictions, navigational areas, fishery rights factors, additional costs, berth length, depth of berth, size of the port yard, port berth bearing pressure, interference with other cargo, a civil appeal, and relevant industrial aggregation. The ports of Tongyeong, Samcheonpo, Kohyun, Masan, and Jinhae in Gyeongsangnam-do were selected and evaluated. As a result, the port of Tongyoung was superior in terms of distance from the Yokji island offshore wind farm. The ports of Samcheonpo, Masan, and Jinhae were evaluated as excellent in other criteria such as berth length, depth of berth, and so on. This study is expected to be used as a source of basic data for offshore wind power companies and policymakers to select and evaluate the supporting ports of offshore wind farms.

This research examines empirically the causal relationship among service quality, CSR, trust, customer-company identification(=CCID), customer's behavioral intention as well as the mediating effect of trust and CCID on the relationship between service quality, CSR and customer's behavioral intention in insurance industry. With this background, this study conducted a statistical analysis based on survey data collected from insurance customers. The result of this empirical study is as follows. First, insurance company's CSR activity has a positive impact on customer's trust and customer-company Identification( =CCID). Second, both customer's trust and CCID have positive and significant effect on customer's behavioral intention. Third, we also find that both trust and CCID has a mediating effect on the relationship between service quality, CSR and customer's behavioral intention. This research shows that CSR activity of insurance company can enhance both customer's trust and CCID, in turn, when CSR activity and service quality is mediated by customer's trust and customer-company identification, it could be linked to customer's behavioral intention such as repurchasing, positive WOM(=word of mouth). This study is likely to contribute to CSR and service marketing research of insurance company.

Today, one of the important factors that determine the university rating is the employment rate. The jobseekers are using online or offline recruiting services in order to get the desired job information. There are lots of employment supporting systems as like web-based employment agencies and University's job centers, but they are focusing more on providing job information rather than on managing the employment support. In addition, those are insufficient to support business process associated with MOU companies, industry field training, mentoring processors, etc., and to continue to manage and to update the information (resume, personal statement, etc.) about the students which the companies want, and the information about the companies which jobseekers want. Therefore, it is required that the employment supporting system which not only storages the initial data (student and corporate information), but also assist the career placement. In this paper, we considered the specific employment rights management features of the existing employment support system, it could receive real-time job information in the smart phone, we presented the design and construction of the system linked to the Bachelor Information System.

Remicade is a therapeutic biosimilar natural antibody in which the mouse variable domain has been linked to the human constant domain. It is a chimeric monoclonal antibody specific to tumor necrosis factor-alpha (TNF-α) and has been developed for the treatment of rheumatoid arthritis. To investigate the biological activity of the Remicade antibody, we carried out a bioinformatics study using a protein data bank to characterize the TNF-α antigen binding mechanism of the Remicade natural antibody. Because the production of the Remicade antibody is often limited by genetic instability of the natural antibody-producing cell, we generated a Remicade single-chain variable domain fragment antibody (Remicade) in which a heavy chain variable domain (VH) is joined with a light chain variable domain (VL) by a polypeptide linker. Furthermore, Remicade was fused to a leucine zipper (RemicadeScZip) for higher production and higher antigen-binding activity than Remicade. The Remicade and Remicade ScZip were expressed in Escherichia coli and purified by a Ni⁺-NTA-agarose column. As expected, the purified proteins had migrated as 28.80 kDa and 33.96 kDa in sodium dodecyl sulfate-polyacrylamide electrophoresis. The TNF-α antigen binding activity of Remicade was not observed by ELISA and western blot. In contrast, RemicadeScZip showed antigen-binding activity. Additional bio-layer interferometry analysis confirmed the antigen-binding activity of RemicadeScZip, suggesting that the leucine zipper stabilized the folding of RemicadeScZip in a denatured condition and improved the TNF-α antigenbinding activity.

For the sake of the Restoration(to the original state) of "Sanbeon-bang(刪繁方)", in this study observed carefully the bibliographical results of "Oedaebiyo-bang", "Cheongeumyo-bang", "Cheongeumik-bang" and "Uisim-bang", which directly quoted "Sanbeon-bang". "Sanbeon-bang" is mostly remained in "Oedaebiyo-bang", and the other provisions of "Sanbeon-bang" mostly lie scattered in "Cheongeumyo-bang" and "Cheongeumik-bang", established 100years before "Oedaebiyo-bang" and "Uisim-bang", established 200years after "Oedaebiyo-bang". And there are few other documents which quoted the "Sanbeon-bang". "Cheongeumyo-bang", a synthetic medical work was compiled in 652, and which refered large quantity of medical documents before Dang-dynasty(唐代) by Son Sa-mak(孫思邈). And he linked the technical opinion of himself. The comments of medicine, as well as the prescriptions are refleting the outcome before Dang-dynasty systematically. For the most part of the medical arguments in "Sanbeon-bang" lie scattered in "Cheongeumyo-bang". "Cheongeumik-bang", also a synthetic medical work which is for the sake of supplement of "Cheongeumyo-bang" was complied in 682 by Son Sa-mak. As well as "CheongeumYo-bang" it doesn't make clear the sources of quotation from "Sanbeon-bang". So it used as the data for confirmation. "Oedaebiyo-bang" was compiled in 752 of Dang-Dynasty by Wang Do(王燾) the a governor-general of Eop-gun. Wang Do was descended from a noble family, and usually visited the palace and dealed with large number of books in Hongmunguan(弘文館), the national library. He programmed the book on the base of wide scopic collection of medical documents. And he took charge of gverment post at the same time as Wang Bing(王氷) who compiled "Chaju-Hwangje-Naegyeong-Somun(次注黃帝內經素問)" in 762. So we can guess they might have seen the same documents and holded the medical knowledge in common. The 40 volume "Oedaebiyo-bang" was a great medical complete book in those days. In particular, it became the model of medical complete books of after ages. The description of the book is mostly the qutation of medical documents of before ages. The character is recording of quotation documents and the order of volume. On the base of the recording, we can reconstruct the table of contents of Sanbeon-bang. By way of the contens, we can understand the purpose of "Sanbeon-bang". Besides, I can see a lot of qouotations of "Sanbeon-bang" in "Cheongeum-bang" and "Uisim-bang" are repeatedly quotated in "Oedaebiyo-bang". For that reason, I observed the bibliographical results of "Oedaebiyo-bang" in detail. "Uisim-bang" was compiled in 982 by the Japanese Niwayasyori(丹波綱賴). It followed the example of the structure of "Oedaebiyo-bang", refered to the contents of "Cheongeumyo-bang", collected chinese medical classic books spreaded in Japan. It contains medical documents of before Su-Dang(隋唐)-era, indicated the source of quotation. The importance of the book is summarization and preservation of large quantity of chinese medicine before 10th century. In this study, a lot of the quotation in "Uisim-bang" from "Sanbeon-bang" were not in "Oedaebiyo-bang".

Objectives PRAL (Prunus armniaca Linne Var) is a herbal formula in Oriental Medicine, known for its anti-inflammatory and anti-allergenic properties. However, its mechanism of action and the cellular targets have not yet been found enough. The purpose of this study is to investigate the effects of PRAL on Th2 cytokines expression in MC/9 mast cells. Methods The effect of PRAL was analyzed by ELISA, Real-time PCR, Western blot in MC/9 mast cells. mRNA levels of GM-CSF, IL-4, IL-5, IL-6, IL-13, TNF-${\alpha}$ were analyzed with Real-time PCR. Levels of IL-13, MIP-$1{\alpha}$ were measured using enzyme-linked immunosorbent assays (ELISA). NFAT, AP-1 and NF-${\kappa}B$ p65 were examined by Western blot analysis. Results PRAL inhibited GM-CSF, IL-4, IL-5, IL-6, IL-13, TNF-${\alpha}$ mRNA expression in a dose dependent manner. GM-CSF, IL-4, IL-5 mRNA expression were inhibited significantly in comparison to DNP-IgE control group at concentration of 100 ${\mu}g/ml$ and IL-6, IL-13, TNF-${\alpha}$ mRNA expression were inhibited at concentration of 50 ${\mu}g/ml$, 100 ${\mu}g/ml$. PRAL also inhibited the IL-13, MIP-$1{\alpha}$ production significantly in comparison to DNP-IgE control group in a dose dependent manner. IL-13 production was inhibited at a concentration of 200 ${\mu}g/ml$, 400 ${\mu}g/ml$ and MIP-$1{\alpha}$ was inhibited at a concentration of 100 ${\mu}g/ml$, 200 ${\mu}g/ml$, 400 ${\mu}g/ml$. Western blot analysis of transcription factors involving Th2 cytokines expression revealed prominent decrease of the mast cell specific transcription factors including NFAT-1, c-Jun as well as NF-${\kappa}B$ p65 but not NFAT-2 and c-Fos. Conclusion These results indicate that PRAL has the effect of suppressing Th2 cytokines production in the MC/9 mast cells. These data represent that PRAL potentiates therapeutic activities to the allergic disease by regulating Th2 cytokines in the MC/9 mast cells.

Purpose: Corporate social responsibility is a self-regulating business model that helps a firm be socially accountable to the public. By practicing corporate social responsibility, firms can be conscious of the kind of impact they are having on all aspects of society, including economic, social, and environmental. Corporate social responsibility activities are not directly linked to increasing corporate performance and corporate value, but rather involve spending expenses. Based on these facts, this study verifies whether the effects of corporate social responsibility activities differ depending on the firm's situation. Research design, data and methodology: This study analyzed the effect of market competition on corporate social responsibility activities using logistic regression analysis on listed companies in the KOSPI and KOSDAQ for fiscal years 2014 through 2016. In this study, market competition was measured using the Herfindahl-Herschman Index(HHI). Higher HHI value can be interpreted as a lower degree of market competition. We also measured corporate social responsibility activities using the KEJI Index published by the Korea Economic Justice Institute (KEJI). If a firm-year is included in the top 200 companies of the KEJI Index, it is classified as a good corporate social responsibility activity firm. Results: We find that companies in less competitive market were not included in the KEJI Index. This result indicates that firms in the market with lower market competition perform less corporate social responsibility activities that incur costs. An additional analysis showed that there was a significant negative relationship between the market competition and the corporate social responsibility activity scores published by the KEJI Index. These result adds robustness to the result of the hypothesis that firms that have a monopolistic place in the market practice passive corporate social responsibility activities. Conclusions: The results show that managers of a firm in the lower market competition have a lower incentive to use limited resources for projects that are not directly related to revenue. The results of this study imply that corporate social responsibility activities vary according to the position of the business. Therefore, this study suggests that market investors should consider the degree of competition in the market when they evaluate corporate social responsibility activities.

The purpose of this study was to examine the relationship between maternal age and infant mortality in Korea(n=617,867). Data of Korean vital statistics linked National Infant Mortality Survey conducted on births in 1999 were used in this study. The odds ratios (ORs) of infant death by maternal age were estimated with the multiple logistic regression model, adjusting for gender, plurality, birth order, low birth weight, and congenital malformation. After adjusting for the relevant variables, the odds of infant death in the group of maternal age with less than 20 years(Odds ratio [OR], 5.29, 95% confidence interval [CI], 3.51-7.98), 20-24 years(OR, 1.44, 95% CI, 1.23-1.69), 35-39 years(OR, 1.28, 95% CI, 1.11-1.46), and more than 40 years(OR, 1.94, 95% CI, 1.53-2.45) was higher than that of reference group(25-29 years). In conclusion, the higher infant mortality in the group of maternal age with less than 25 years and more than 35 years in Korea appears to be due to higher proportion of low birth weight and pre-term birth. Prenatal care intervention programs which tackle biological factors for advanced maternal age and address socio-economic problems and social stigma for early maternal age should be devised.

Objectives : The purpose of this study is evaluating the effect of Poria cocos pharmacopuncture (PCP) at $SP_6$(Sameumgyo) and $ST_{36}$(Joksamni) on chronic stress model(CSM) rats. Methods : The experimental rats were assigned to five groups: normal, CSM(control), PCP1X, PCP2.5X and PCP5X. The experimental rats in CSM(control), PCP1X, PCP2.5X and PCP5X were put through a timetable to cause CSM. PCP($20{\mu}l$) was administered at $SP_6$, $ST_{36}$ to groups PCP1X, PCP2.5X and PCP5X once every three days for a total of six times. The weight of the rats was measured by an electronic scale after PCP injection, once every three days for a total of six times. Blood samples were taken from the rats for analysis of aspartate aminotransferase(AST) and alanine aminotransferase(ALT). Serotonin and norepinephrine were measured by enzyme-linked immunosorbent assay(ELISA) kit. Results : The experimental groups(PCP1X, 2.5X, 5X) showed significant body weight increase compared to the control group. Regarding AST and ALT changes in serum, the experimental groups(PCP2.5X, 5X) showed a significant decrease compared to the control group. For Serotonin changes in serum, the experimental group(PCP5X) showed a significant increase compared to the control group. For Norepinephrine changes in serum, the experimental groups(PCP2.5X) showed a significant decrease compared to the control group. Conclusions : These data suggest that PCP at $SP_6$, $ST_{36}$ has therapeutic effects on CSM rats.

The Korea Wave has been spread out all over the world since 1990s. Therefore, it can be seen that the Korea wave phenomenon is one of determinants of international tourism demand for Korea in addition to the macro factors such as population, GDP per capita, exchange rate, distance, etc. Existing studies have focused on analyzing the impacts of the Korea wave on the international tourism demand for Korea by using the aggregated data. However, the impacts of the Korea wave inducing tourism vary in different age groups. In this study, we conduct empirical analysis in order to explore how different the effects of Korea wave on the demand of foreign tourists visiting to Korea in different age groups are. The estimation results show that the Korea Wave influences most on international tourism demand for Korea in the age group of the under-20s. Noticeable is that the estimated effects of the Korea Wave on international tourism demand for Korea in the age group of the over-50s are higher than those in the 30s and 40s. This indicates that the parent generations visit Korea together with their young children who are most affected by the Korea Wave. Through this study, it is necessary to develop strategies for tourism marketing linked to children and parents, and to develop tourism products to increase the number of foreign visitors to Korea in the 30s and 40s.
