According to the OECD (2015) and UN (2017), Korea was classified as an immigration country. The designation as an immigration country means that net migration will remain positive and international migration is likely to affect population growth. KOSTAT (2011) used a model with more than 15 parameters to divide sexes, immigration and emigration based on the Wilson (2010) model, which takes into account population migration factors. Five years later, we assume the average of domestic net migration rate for the last five years and foreign government policy likely quota. However, both of these results were conservative estimates of international migration and provide different results than those used by the OECD and UN to classify an immigration country. In this paper, we proposed a stochastic projection on international migration using nonparametric model (FDM by Hyndman and Ullah (2007) and Coherent FDM by Hyndman et al. (2013)) that uses a functional data model for the international migration data of Korea from 2000-2017, noting the international migration such as immigration, emigration and net migration is non-linear and not linear. According to the result, immigration rate will be 1.098(male), 1.026(female) in 2018 and 1.228(male), 1.152(female) in 2025 per 1000 population, and the emigration rate will be 0.907(male), 0.879(female) in 2018 and 0.987(male), 0.959(female) in 2025 per 1000 population. Thus the net migration is expected to increase to 0.191(male), 0.148(female) in 2018 and 0.241(male), 0.192(female) in 2025 per 1000 population.

This study was carried out to examine whether the moderated mediating effect of SNS addiction resulting from marital dissatisfaction and loneliness is influenced by gender or size and composition of social capital. 714 married men and women in their 20's to 40's were participated in this study. The data were collected by online research center with quota sampling based on demographical proportion. To analyze this research model, the moderated mediating effect utilizing structural equation was used. The results of this study were summarized as follows. First, it is verified that the loneliness moderated between marital dissatisfaction and SNS addiction. Since the relationship between independent and dependent variable is insignificant, comparison of competition model was able to determine if mediating effect was fully or partially shown. As a result, the complete mediated model was ultimately chosen because its various goodness-of-fit index including $x^2$ performed fairly well. Second, the mediating effect which moderates social capital size was presented in the mediated model between the marital dissatisfaction, loneliness and SNS addiction. Specifically, It implies that group who recognizes their social capital big recognizes the route and effect size more than that who considers their social capital small. And the moderated mediating effect depending on different type of social capital among the marital dissatisfaction and loneliness and between SNS addiction was substantiated. It implies that disequilibration of SNS social capital in face-to-face sphere and in online acted as a danger fact with respect to the marital dissatisfaction, loneliness and SNS addiction. The implications of these findings were discussed, and directions for future studies were also proposed.

The purpose of this study is to explore some policy implications for improving the faculty personnel management and their salary scheme of the Korean national universities through comparing the systems and practices of Korean national universities to those of OECD countries. The fact that many leading OECD countries in higher education arena have been taking decentralized contract-based system based on institutional autonomy and performance beyond the previous bureaucratic control model casts some significant implications for the Korean national university reform. Especially, concerning on personnel management, it is necessary to provide more flexibility in managing faculty personnel categorization and expansion of faculty quota management for faculty and to review the maintenance of faculty's legal status as civil servant. In addition, regarding the salary scheme of faculty, we suggested performance-based salary scheme with plus-sum methods, settlement of rational faculty performance evaluation system and practices, and need for some aligning efforts for changing faculty salary scheme of the national universities.

The purpose of this study is to propose a theoretical model for understanding how marital satisfaction and depression may impact on suicide ideation of older people. This study was also focused on the mediating effect of depression. To achieve this purpose, a survey was conducted, and this sample was based on 194 older people aged over 65 living in Jeollabuk-Do, who had been participating in senior centers or in home care centers. A sampling method was the quota sampling using face to face interview, and an analysis method was the structural equation modeling. The main results testified by this study are as follows; First, the negative function of marital satisfaction had direct effect on the suicidal ideation and depression, while the positive function of depression had direct impacts on the suicidal ideation. Second, the depression mediated partially the association between marital satisfaction and suicidal ideation. This study theoretically contributes to the existing literatures documenting the impact of marital satisfaction on older people' suicide ideation. Not only that, but this study suggests practical and politic implication through these results.

The objective of this paper is to analyze the disparities in perceptions regarding gender-related matters among students at K University, determined by their gender, and to propose solutions within the university education system. The results of the study are as follows. First, many men believe that there is no structural discrimination against women and that men are discriminated against, whereas women show the opposite. Second, men and women show statistically significant differences in perception of women's level of effort, reasons for low income, and work ability after employment. Third, men show unfavorable attitudes towards feminism compared to women. Fourth, the reasons men show hostile attitudes toward the female quota system and feminism include the influence of the traditional gender role model imposed on men and the difference in men's and women's views on structural inequality. To reduce the perception gap between men and women, it is necessary to reconsider hegemonic masculinity, apply issue-centered education using accurate information, publicize issues by preparing a mistake-friendly space, and respond to the perception gap at the university level from the perspective of citizenship education.

The purpose of this study is to provide policy recommendations for manpower planning by forecasting the supply and demand of Medical Technologists. Supply was estimated using an in-and-out movement method with a demographic method based on a baseline projection model. Demand was projected according to a demand-based method using the number of clinico-pathologic examinations taken for Medical Technologists. Over- or undersupply of Medical Technologists will depend on the productivity scenario and assumptions and ultimately on governmental policy direction. In other words, whether the production of Medical Technologists is higher or lower than the current level depends on the government policy to consider insurance finances. In this study, we assessed 'productivity scenario 3' based on the productivity as of 2012, when the government's policy direction was not considered. Based on the demand scenario using the ARIMA model, the supply of Medical Technologists is expected to be excessive. This oversupply accounts for less than 10% of the total and therefore should not be a big problem. However, given that the employment rate of Medical Technologists is 60%, it is necessary to consider policies to utilize the unemployed. These measures should expand the employment opportunities for the unemployed. To this end, it is necessary to strengthen the functions of laboratories in the public health center, to increase the quota of Medical Technologists, to assure their status, to establish a permanent inspection system for outpatient patients, and to expand the export of Medical Technologists overseas.

The purpose of this study was to investigate the causal relationship among perceived value, satisfaction and revisit intention for visitors of the Korea National Arboretum. Three hundred respondents were selected by quota sampling, and well-known measurement scales utilized in marketing field were adopted in order to measure three variables with some modification to apply for arboretum visitors. Results of structural equation model showed that perceived value affected visitors' satisfaction, which in turn influenced revisit intention. Specifically, "emotional value" had the most significant influence on satisfaction, followed by "value for money" and "novelty value"; however, "social value" was not an influential construct. Based on calibration results, several strategies were suggested for the effective management. Authors advised that (a)improvement of measurement scale of value, (b)inclusion of self-congruity as antecedent variable to satisfaction, (c)changing revisit intention to word-of-mouth communication as a post-purchase behavioral intention, and (d)implementation of market segmentation should be considered for future research.

In order to overcome the disadvantages of banner ad, pop-up ad, interstitial ad, which are existing web advertisement forms, native ad is actively utilized. Native advertising is considered to be a useful advertising technique in that it can reduce users' rejection and attract attention. However, in recent years, there have been a lot of fake news and fake contents that have turned articles or video contents into advertisements. The purpose of this study is to understand how firms can coordinate and control native advertisements in a rational way. For this analysis, we conducted a survey of 308 social media users using quota sampling method. As a result of the verification, it was found that the more negative the perception of the evaluation of the advertisement, the less the level of persuasion about the advertisement and the negative impact on the website where the advertisement is exposed. In addition, this study examined the influence of the negative stimulus factors on the qualitative performance of the firm. As a result, it was found that source non-expert had the highest effect on skepticism on ad. Also, platform overflow has a direct effect on the evaluation of the website as well as the negative evaluation of the advertisement. Moreover, this study provides concrete implications for the subdivision market by verifying the differences between the paths according to the level of website involvement.
