This study investigates the facilitating factors of FDI (foreign direct investment) inflows in 15 developing countries of three continents (Asia, Latin America, and Africa) using fixed-effect panel regression analysis with 30-year macro socio-economic data. The facilitating factors of FDI inflows in each continent differed. In Asia, labor compensation, GDP, consumer expenditure, human capital, and export facilitated FDI inflows in decreasing order, as did export, total factor productivity, GDP, and human capital in Latin America, and investment expenditure, human capital, government expenditure, and export in Africa. Most importantly, the character of cost saving efficiency-seeking investment was very strong in Asia. Also, third-party export-oriented investment and economic growth-oriented investment were shown in Latin America and Africa, respectively.

본 논문에서는 비상운전 상황하에서 표출되는 운전원들의 직무전략 및 인지적인 특성을 도출하기 위해 운전원 교육 프로그램을 대상으로 운전원들의 직무특성을 분석하였다. 운전원들의 직무특성을 인지과정의 개입 정도에 따라 크게 Macro와 Micro로 구분하여 이들 직무특성을 잘 대변해 줄 수 있는 비상운전 시나리오를 개발하였다. 시뮬레이터를 통해 개발 시나리오에 따른 운전원들의 비상운전절차 수행과정을 비디오로 기록, 운전원들의 행동과 대화내용을 전산 분석하여 직무특성을 도출하였다.

The purpose of this study was to examine the dual mediating effects of growth mindset and hope between body image and successful aging of the elderly. For this purpose, we surveyed 422 elderly people in D and S city of Chungcheongnam-do, and D metropolitan city. Collected data were analysed using SPSS 25.0 and PROCESS macro 3.4 program. Frequency analysis, reliability analysis and dual mediating effect analysis by using bootstrap were performed. The results of the study are as follows. First, as a result of correlation analysis there was a statistically significant positive correlation between variables. Second, as a result of path analysis, body image had a positive effect on growth mindset and hope, growth mindset had a positive effect on hope and successful aging, and hope also had a significant effect on successful aging. Third, as a result of dual mediation effect analysis, growth mindset and hope mediated in the relationship between body image and successful aging. This study provided new models and basic data by using body image, growth mindset and hope for successful aging of the elderly.

Tracking is a process which explores user equipment (UE) in the area of tracking in terms of cells. In this paper, two tracking schemes based on macrocell-microcell tiers in hierarchical LTE networks, PMMT and IMMT, are evaluated. In this network, UE can receive a signal from macrocells and overlapping microcells, and can be called from each macrocell or microcell-tier in the PMMT. Also, the UE can be called from the combined macrocell-tier and microcell-tier in the IMMT. Finally, we analyze the optimization of load balance between marcocell-tier and microcell-tier, and an analytical model is developed to evaluate those two arrangements.

기존의 트라이볼로지 분석 기법은 macro 영역에서 시료의 강도 및 탄성 등의 물성을 분석하는 정도였으나 Nano-Indenter 분석 기법은 macro 영역보다 더 미세한 nano 영역에서의 시료 물성 분석을 가능하게 해주었다. 따라서 본 연구에서는 시료들의 결정 배양 방향에 따른 Nano-Indenter 압입 각도 차이에 대한 nano 영역에서의 연구를 진행하였다. Si 기판 외에 본 연구에 사용 된 HfN 및 Zr 박막의 시료들은 rf magnetron sputter를 이용하여 약 100 nm 두께로 증착하였다. 각각 시료들에 대한 결정성 확인을 위해 XRD 분석을 실시하였다. 이후 Nano-Indenter를 이용하여 압입 인가력 대비 압입 깊이를 측정하였다. 이 과정에서 Nano-Indenter 압입 각도를 $0^{\circ}$와 $90^{\circ}$로 변화함에 따라 압입 인가력 - 압입 깊이 그래프의 차이를 확인하였고 이를 기준점으로 부터 $10{\mu}m$ 이격시켜 16회 반복 측정과 Weilbull distribution을 통해 신뢰도를 향상시켰다. 측정 결과 Zirconium(Zr) 박막의 경우 21.53 GPa과 22.18 GPa 측정되었으나 Si 기판은 17.46 GPa 16.33 GPa으로, 그리고 HfN 박막의 경우 25.18 GPa과 27.75 GPa으로 상대적으로 큰 차이를 확인하였다. Si 기판과 HfN의 측정결과 Weibull distribution는 75.02와 70.23인 반면 Zr 박막은 30.94로 상대적으로 불균일한 특성을 확인하였다. 이 결과들로부터 각각의 박막 결정 배양 방향에 따른 분석의 한가지 방법으로 Nano-Indenter 분석 기법을 사용할 수 있는 가능성을 확인하였다.

The main purpose of the archives is to maintain a history of the organization's functions and activities. Selecting valuable records for the permanent archives through objective appraisal from among many records that reflects the activities of organization is very important but also very difficult. The quantity and complexity of comtemporary records has rapidly expanded because of electronic storage, and with the information environment, and it is now possible to manage and control the records an entire lifetime. In this study, it is proposed the appraisal methods based on a business analysis that is combined the macro-appraisal factor and micro-appraisal factor; The former is functions and organizations as the objective guideline of selecting valuable records from the beginning and the latter is a contents appraisal (evidential value) of the individual records.

Construction industry is broadly agreed as one of the most important sectors of any economy around the world. In this paper, time series data of Korean construction industry and Korean economy are examined. The Bon's proposition will be inspected for Korean context using both cross-sectional and longitudinal analyses. The analysis of the longer than four decades national account statistic of the Korean macro economy verify Bon's proposition of an inverted U-shaped relationships. The verified U-shaped relationships for Korean context exist not only in terms of the construction share in total GDP but also in terms of total construction volume as an economy develops from LDC to NIC and then to AIC eventually with time. The results of the thesis show that the contribution towards the macro economy has varied across different stages of development.

The objective of the study was to determine the mediation effects of hope and grit in the relationship between human rights damage and self-esteem. A sample of students was recruited from two universities in Korea. For data analysis, SPSS PC+ and SPSS PROCESS macro were used. Frequency, reliability, correlation and mediating effect analysis were performed. Bootstrap technique was done to verify the mediating effect. Results showed as follows. First, grit, self-esteem and hope were negatively correlated with human rights damage, but grit, self-esteem and hope were positively correlated with each other. Second, hope and grit mediated in the relationship between human rights damage and self-esteem. For further research, it was discussed how university students who experienced human rights abuses could use grit and hope to maintain their lowered self-esteem.

Since the stock price is a measure of the future value of the company, when analyzing the stock price, the company's growth potential, such as sales and profits, is considered and invested in stocks. In order to set the criteria for selecting stocks, institutional investors look at current industry trends and macroeconomic indicators, first select relevant fields that can grow, then select related companies, analyze them, set a target price, then buy, and sell when the target price is reached. Stock trading is carried out in the same way. However, general individual investors do not have any knowledge of investment, and invest in items recommended by experts or acquaintances without analysis of financial statements or growth potential of the company, which is lower in terms of return than institutional investors and foreign investors. Therefore, in this study, we propose a research method to select undervalued stocks by analyzing ROE, an indicator that considers the growth potential of a company, such as sales and profits, and predict the stock price flow of the selected stock through deep learning algorithms. This study is conducted to help with investment.
