The purposes of the study are to investigate Koreans' perception about Vietnam by analyzing social big data and to seek changing direction in perception. For the purposes, the texts about Vietnam in Naver Blog and Twitter and the number of search and click for Vietnam in Naver were analyzed by Social Metrics of Daum Soft and Datalab of Naver. The study also analyzed the annual change of their interest in Vietnam based on social media. The results showed that Koreans still remember the Vietnam war, have a positive emotion toward Vietnam, and view Vietnam as a country where we can gain mutual benefit by exchange. The findings also indicated that Koreans perceive Vietnam as a favorite tourist spot regardless of age. Meanwhile, children under 12 showed a different pattern of an annual change in perception. It might be a positive sign that Koreans' interest region toward Vietnam would be diversified because children under 12 would be the central axis of cultural contents.

This study is aimed to compare cross-cultural individualism, and consider an influence of nationality, gender and age on individualistic propensity. The survey data include 271 Chinese, 251 Japanese, 262 Netherlander and 267 Korean. The result of factor analysis, four factors named independent action, profit and opinion, indifference on other and will, were found out. The result of comparison on nationality, Netherlander and Japanese has a strong individualistic propensity, and Korean has a remarkable collective propensity. Chinese were middle grade among 4 countries. It can be said that certain factors correlated with a certain country, because Netherlander's answer on questions belonged to profit and opinion factor were highest, and Japanese's one belonged to indifference on other were highest. On gender, Man was more individualistic better than woman. On age, twenties has strong collective propensity better than other age groups. The number of significant difference on comparison among countries is 21 in 21 questions, but the number on gender or age is 6 or 7. Therefore, it can be said that nationality (or culture) is most useful variable to grasp individualism.

The Namwon and Sunchang granites are neighbouring plutons intruding the Yeongnam massif and the Okcheon metamorphic belt, respectively in the southwestern part of the Korean peninsula. In this study, SHRIMP zircon U-Pb ages are determined from these plutons. The results show that the emplacement age of the Namwon granite is $185.8{\pm}0.9(2{\sigma})$ Ma. We obtained $175.0{\pm}2.0(2{\sigma})$ Ma from the northern part and $179.8{\pm}0.9(2{\sigma})$ Ma from the central part of the Sunchang granite, yielding $177.4{\pm}1.3(2{\sigma})$ Ma as the average age of the pluton. Such age results confirm that the Honam shear zone, which cause marked deformation of the Sunchang granite, was active after ca. 175 Ma.

Recently, adipose mesenchymal stem cells (AdMSC) that are similar to bone marrow MSC and blood derived MSC are thought to be another source for stem cell therapy. However, the diseases that can be applied for stem cells therapy are age-dependent degenerative diseases. Accordingly, the present study investigated the growth and differentiation potential to neural cells of human AdMSC (hAdMSC) obtained from aged thirty, forty and fifty. The growth of cells and cell viability were measured by passage and neural differentiation of hAdMSC was induced in neural differentiation condition for 10 days. Our results demonstrated that cell number, viability and morphology were not different from hAdMSC by age and passage. Immunofluorescence analysis of neural cell marker (TuJ1, NSE, Sox2, GFAP or MAP2) demonstrated no significant differences in neural cell differentiation by age and passage. As the number of passage was increased, the mRNA level of MAP2 and Sox2 was decreased in hAdMSC from age of 50 compared to hAdMSC from age of 30. In conclusion, the present study demonstrated that ability of neural cell differentiation of hAdMSC was maintained with ages, suggesting that autologous stem cells from aged people can be applied for stem cell therapy with age-dependent neural disease with the same stem cell quality and ability as stem cell derived from young age.

This study would analyze the visual expression elements, including layout, color, picture and typography in the election posters with the five main candidates of the 19th Presidential Election as the targets of the analysis. This study analyzed the candidates' images in the election posters and conducted a survey of the visual expression elements survey by the age of the voters. As a result of the analysis, Presidential Candidate Moon Jae-in felt fresh, and Yoo Seung-min like Moon had high percentages in layout and color, highlighting his clean image. Hong Jun-pyo had the most diverse preferences by age, and Ahn Cheol-soo, who showed the most unprecedented poster, too, had diverse preferences by age. Shim Sang-jung, who emphasized her familiar image, had preferences for her visual expression elements by all age groups in the following order: layout, color, picture and typography. Therefore, in order to utilize the visual expressions of the election posters, effectively, it is necessary to clarify the messages that the candidates would claim. For this purpose, objective research should continue so that they can be further developed artistically and academically through broad understanding and analysis of the voters rather than subjective expressions.

This study aims to examine the differences of Humor Preferences and Uses by the distinction of sex and age. For this purpose, an experimental survey was analyzed. The major findings of this analysis could be summarized like as follows: There is few significant difference in the sex distinction, although men prefer aggressive humor more than women. But there are significant differences in the distinction of age. The teenagers prefer nonverbal humor compare to other ages, and the over forties prefer verbal humor. There are also significant differences of humor uses between age groups. The under twenties use humor more than over thirties. This study deliberates on the reason why there are significant differences of humor preferences and uses in the distinction of age. This study suggests one of the reasons which is related with face consciousness of korean.

In addition to aging social problem, the problem of older age structure ratio in the fire service organization playing the leading role of the disaster response activities is also expected to be this serious situation. In the case of Seoul fire fighting organization, it is expected that the ratio of over the age 50 reaches 31% or 40% between from 10 to 15 years later from now on, but this will be a serious problem in the fire fighting personnel needing a healthy body and physical strength in the disaster situation unlike the civil servants of general staff. Therefore, the purpose of this study is to take measures that can adapt to a new disaster environment of Increasing proportion of the elderly population by presenting the criteria of age limit of fire fighting field activities to analyze the relevance of the ability to perform on-site activities and age of Seoul fire civil servants, by using three analysis criteria.

Age and growth of the robust tonguefish, Cynoglossus robustus were estimated using scale of 353 fish specimens from February, 2004 to December, 2005 in the Southern Sea of Korea. Marginal increment of the scale formed annual rings from October to November at the beginning of autumn season. In the relationship between total length and body weight, a multiplicative error structure was assumed because variability in growth increased as a function of the length, and the estimated equation was $BW=0.0013TL^{3.399}$ ($R^2=0.916$). The relative growth as body weight at total length has significant difference between females and males (p<0.05). For describing growth of the robust tonguefish, C. robustus a von Bertalanffy growth model was adopted. The von Betalanffy growth curve had a additive error structure and the growth parameters estimated from Walford method were $L_{\infty}=43.77cm$, K=0.186/year and $t_0=-2.295year$. Growth at age of females and males shows no significant difference (P>0.05).
