The purpose of this study is to analyse economic preparations for aging of the middle and old-aged and their determinants empirically, and then to discuss the findings and implications for the results of analysis. Data from The Social Statistics Survey conducted by Korea National Statistical Office are used in this study. From this dataset, 18,354 Middle and Old Citizens aged between 45 and 59 were selected for this study. The Conceptual framework for this study was based on Andersen's behavioral model and logistic model was used to investigate factors that affect economic preparation for aging. The results of this study can be summarized as follows. First, Proportion of middle and old citizen with no economic preparation for aging was high, and old-aged had lower level of economic preparation for aging than relative less aged. Second, male, education level, marital status, economic activities, recognition of present income, housing ownership, residental location, and total life condition improvement is positively and statistically significantly associated with economic preparations for aging. Third, while male, age, and economic activities is negatively and statistically significantly associated with private economic preparations for aging, education level, recognition of present income, and total life condition improvement is positively and statistically significantly associated with private economic preparations for aging. Fourth, while male, education level, marital status, economic activities, recognition of present income, housing ownership, residental location, and total life condition improvement, expectation of future income is positively and statistically significantly associated with secondary economic preparations for aging, age is negatively and statistically significantly associated with secondary economic preparations for aging.

The evolutionally conserved TREX complex member, Yra1/ALY, belongs to the REF (RNA and export factor binding proteins) family of hnRNP-like proteins, which has been implicated in multiple processes including transcription, nuclear RNA stability, and mRNA export. Fission yeast, Schizosaccharomyces pombe, genome encodes two members of REF proteins. In addition to Mlo3 known previously as an mRNA export factor, there is the other REF protein, Tho4, which is predicted as a component of THO complex. Here we showed that deletion of tho4 (SPBC106.12c) gene does not inhibit both growth and nuclear mRNA export. However, overexpression of tho4 displays growth retardation and slight accumulation of $poly(A)^+$ RNA in the nucleus. Neither ${\Delta}tho4$ ${\Delta}mlo3$ nor ${\Delta}tho4$ ${\Delta}mex67$ double mutants exhibit additive growth defect. Moreover, yeast two-hybrid and co-immunoprecipitation analysis did not show that the Tho4 protein interacted with any members of TREX complex and mRNA export factor Rae1. Contrary to expectation, these observations support that the S. pombe Tho4 is not a component of TREX complex, and not directly involved in bulk mRNA export from the nucleus.

The goals of the study were to examine if and how exposure to suicidal factors in social relationships affects suicidal ideation and behaviors and also analyze how family factors are associated with suicidal ideation and behavior. Data drawn from Korean General Social Survey(KGSS) collected in 2009 were analyzed. The findings show that exposure to the suicidal factors have statistically significant effects on suicidal ideation and behaviors. In the findings, respondents who have experiences of which socially close persons have suicidal ideation or completed suicide are more likely to have suicidal ideation and suicidal plan even in the models for which demographic factors and depressive symptoms are controlled. Also, family factors have significant effects on suicidal ideation and suicidal behaviors. Family stress increases suicidal ideation and behaviors whereas expectation on family support reduces the likelihood of having suicidal ideation and behaviors. This study shows that there might be possibility of behavioral contagion in terms of suicide through social connections and family has both positive and negative aspects on suicidal ideation and behaviors. Our study suggests policy implications for people who were exposure to suicide.

In order to elucidate the precise phylogenetic relationships of Korean wild boar (Sus scrofa coreanus), a partial mtDNA D-loop region (1,274 bp, NC_000845 nucleotide positions 16576-1236) was sequenced among 56 Korean wild boars. In total, 25 haplotypes were identified and classified into four distinct subgroups (K1 to K4) based on Bayesian phylogenetic analysis using Markov chain Monte Carlo methods. An extended analysis, adding 139 wild boars sampled worldwide, confirmed that Korean wild boars clearly belong to the Asian wild boar cluster. Unexpectedly, the Myanmarese/Thai wild boar population was detected on the same branch as Korean wild boar subgroups K3 and K4. A parsimonious median-joining network analysis including all Asian wild boar haplotypes again revealed four maternal lineages of Korean wild boars, which corresponded to the four Korean wild boar subgroups identified previously. In an additional analysis, we supplemented the Asian wild boar network with 34 Korean and Chinese domestic pig haplotypes. We found only one haplotype, C31, that was shared by Chinese wild, Chinese domestic and Korean domestic pigs. In contrast to our expectation that Korean wild boars contributed to the gene pool of Korean native pigs, these data clearly suggest that Korean native pigs would be introduced from China after domestication from Chinese wild boars.

This study analyzes determinants of strategic marketing alliances' performance using 'continuous use intention' of consumers in the Korean credit card industry. Specifically, this study aims to provide comprehensive and synthetic understanding of these factors divided into firm- level and consumer- level variables. Thirty alliance cards were chosen randomly. For firm- level data, managers from the thirty selected cards were interviewed concerning their respective firm and alliance operation. For collection of consumer- level data, 610 card holders from these thirty cards were surveyed concerning card benefits, benefits information, brand image, and continuous use intention. The hierarchical linear model (HLM) was employed to analyze this multi-level data, yielding the following results: First, consumers identified three factors that positively influence continuous use intention. Second, with respect to firmlevel factors, alliance partner's marketing capability is not positively related to intention, whereas fit of alliance goal influences consumer's continuous use of card. Third, contrary to expectation, the positive interaction effects between consumer level variables and firm level variables were found to be not present.

Objectives: The purposes of this study were to investigate CHPs' knowledge, attitude, and practice regarding UI, and to identify predictors of their UI related practice. Methods: A descriptive-correlational study using self-administered questionnaire was conducted. A total of 330 members of the local Korean Association of CHPs were included in this study. A mailed survey was conducted to collect data. Findings: Of CHPs surveyed, 170(51.5%) returned completed questionnaire. Educational preparation of CHPs regarding UI was limited. The mean correct score of knowledge scale was 68.96%. Overall, CHPs exhibited positive attitudes toward UI. CHPs in this study were not actively participate UI related practice. Contrary to expectation, knowledge was not significantly related to CHPs' practice regarding UI. In the final analysis, CHPs' practice regarding UI was predicted by attitude toward the care of UI clients and educational needs for UI and these two variables explained 9% of variance of UI related practice. Conclusion: The results of this study suggest the importance of attitude and educational needs in shaping UI related practice among CHPs. To facilitate UI related practice among CHPs, efforts for attitudinal change related to UI among CHPs are needed. Moreover, continuing educational program for UI management should be developed, applied and evaluated.

In this study the author analysed impact of image of regional festival on satisfaction of tourists and their intention for revisit through an example of firefly festival in Youngyang-kun. Current Firefly Festival of Youngyang is its fifth since its beginning. Unlike festivals in other areas it is held during daytime and nighttime respectively. In it natural environment and ecosystem in Youngyang area are highlighted and it is unique in the sense that such festival is performed with live insects. Festival is organized with various sights to see including experiencing flying fireflies in nighttime and making insects etc. In this study the author analysed impact of image of regional festival on satisfaction of tourists and their intention for revisit. In this connection this author chose 20 items in connection with image of regional festival. Then I carried out analysis on various factors in connection with tourists as appeared in regional festival. I performed analysis on diversity, experience, convenience, conveyance of content of festival and its creativity as factors constituting satisfaction of tourists in connection with image of regional festival. Result of analysis undertaken in this study revealed that image of regional festival and satisfaction of tourists who experienced festivals served to their expressing intention for revisiting. For inducing tourists intention for revisiting image of regional festival, conveyance of diverse information, diversity of program of the festival, new experience, sense of expectation are important. Therefore this is need for development of environment and ecosystem friendly programs and it should be developed as a consistent environment friendly festival rather on temporary touch- and-go event.

While small and medium-sized companies are suffering from a shortage of workers as a result of social tendency to avoid those companies, college graduates still prefer large companies or governmental positions, which consequently results in inconsistencies in the demand and supply of work forces. The gap between them is getting so bad that employment difficulties are exacerbating. Accordingly this study tries to search for potential employee's expected value factors which make people select small and medium companies not big companies. A survey was conducted from October 1 to october 30, 2012 with university students in the Seoul metropolitan area. a total of 350 questionnaires were distributed and 335 were collected. of these, 332 questionnaires were used for data analyses excluding questionnaires with missing values. Data was analyzed by frequency, descriptive factor, reliability, and regression with SPSS win 18.0 program The result of this study were as follows. A factor analysis extracted four factors comprising small and medium companies, which we named career(factor 1), working environment(factor 2), working achievement(factor 3), job security (factor 4). This study showed that small and medium companies' preference were affected by the career, working environment, job security, corporate reputation, salary.

This study examine the overlapping concepts among the brand performance variables such as brand trust, consumer-brand relationship, and brand loyalty in study one after divided consumer-brand relationship into 4 different variables, brand congruity, interdependence, brand nostalgia, brand love. Contrary to expectation, conclusion of factor analysis shows that there exist 4 factors based on eigenvalue. The variables such as brand experience, consumer-relationship, and brand love are divided into several variables and verified the validity of these concepts. We can easily witness this kind of situation because researchers use different scales on same variables Second study suggest brand love is concept that harder to accomplish than brand loyalty. Because the several fit indices of first model that indicate the simple relationships among brand trust, consumer-brand relationship, and brand loyalty are very low to accept, this study propose 4 different models. Conclusion shows that model 3b(love is placed last) is most acceptable thing. And this means love brands like people might be hardest thing to achieve.

SNS allowed users to serve not only as the content and message producer but as the consumer, with development into various types of SNS platforms. Instead of a traditional media structure of media-to-many and unspecified users, it also made it possible to achieve one-to-one or one-to-many interactions, regardless of time and space, through SNS platforms. Moreover, according to development of digital communication technology, IT, media contents and communication network have been mutually connected, though they were once separate. The changes in communication environments have caused rapid disorganization and reorganization in popular culture led by specific expert groups. Such trend has a greater influence on marketing strategies of enterprises. In other words, it will lead them to mostly introduce new information technologies, based on consumer market, and to strategically participate in SNS for promotion and marketing for their products and brands. Likewise, SNS has currently appeared as the main media affecting consumers' behaviors. In consideration of the importance of SNS features, which can stimulate responses of other users, analysis of main features affecting SNS user acceptance decision is required, as well as its utilization strategies. Accordingly, this study conducted division of SNS features into openness, quickness, interactiveness and economical efficiency to derive strategies for increasing the usage frequency of SNS and ultimately maximizing the expectation effect, in addition to an empirical analysis of effects of SNS features on usefulness, easiness and pleasure perceived in SNS, and SNS user intention.
