Korean Longitudinal Study of Ageing(KLoSA)', launched in 2006, has developed a research network with 'Health and Retirement Study(HRS, US),' Studies on Health and Retirement in Europe(SHARE, EU),' and 'English Longitudinal Study of Ageing(ELSA, UK)'and tried to construct a mega data library. The KLoSA team has designed their research with focusing on the following three points, in order to use KLoSA for international comparative studies. First, KLoSA shares the key research areas such as family structure, health, employment, income, asset, subjective expectations with the comparable studies. Second, KLoSA team has developed the instrument to reflect the Korean culture and institutions. They considered the institutional characteristics in public pension and health care system and in employment practices. They also counted the cultural conventions in family life such as financial management and care exchange, Finally, KLoSA tries to capture the psychological characteristics of the Korean elderly by making the measurement scales more understandable.

This research was performed with the aim of analyzing the 'expectation dynamics' of embryonic stem cell research which was revealed throughout the establishment process of Stem Cell Research Center from 2000 to 2002. Expectation dynamics is a chained process: expectation construction - raising fund - performing research. Normally, researchers are considerably circumspect and politically neutral in assessing the result of research. However, some researchers are very involved in building the expectation dynamics by developing an overestimated impact of the result, which can be understood as a kind of strategy for solving the financial problem and defending the criticism in terms of bioethics. Nowadays Biotechnology R&D costs a big budget and requires large site human resources, so building the expectation dynamics is a decisive element for a successful R&D performance, which makes the strategy-development in the political context much more important. By analyzing the actors-network of embryonic stem cell research in term of 'expectation dynamics', we can clarify the identify of embryonic stem cell researchers and draw a conclusion which is very helpful for decision makers and the public to make a decision related with embryonic stem cells.

The concept of CoVaR introduced by Adrian and Brunnermeier (2009) is a useful tool to measure the risk spillover effect. It can capture the risk contribution of each institution to overall systemic risk. While Adrian and Brunnermeier rely on the quantile regression method in the estimation of CoVaR, we propose a new estimation method using parametric distribution functions such as bivariate normal and $S_U$-normal distribution functions. Based on our estimates of CoVaR for Korean banking industry, we investigate the practical usefulness of CoVaR for a systemic risk measure, and compare the estimation performance of each model. Empirical results show that bank makes a positive contribution to system risk. We also find that quantile regression and normal distribution models tend to considerably underestimate the CoVaR (in absolute value) compared to $S_U$-normal distribution model, and this underestimation becomes serious when the crisis in a financial system is assumed.

Due to a recent rise in use of a wireless keyboard and mouse, attacks which take user's input information or control user's computer remotely exploiting the physical vulnerability in the wireless communication have been reported. Especially, MouseJack, announced by Bastille Network, attacks 2.4 GHz wireless keyboards and mice through exploiting vulnerability of each manufacturer's receiver. Unlike other attacks that have been revealed, this allows to attack AES wireless keyboards. Nonetheless, there is only a brief overview of the attack but no detailed information on this attacking method. Therefore, in this paper we will analyze the Microsoft 2.4 GHz wireless mouse packet and propose a way to set the packet configuration for HID packet injection simulating a wireless mouse. We also develop a system with 2.4 GHz AES wireless keyboard HID packet injection using the proposed packet and demonstrate via experiment that HID packet injection is possible through the system we built.

Objectives: Cancer diagnoses have a tremendous impact on individuals and communities, drawing intense public concern. The objective of the current research was to examine news coverage and content related to cancer-related issues in Korean newspapers. Methods: Primarily using the database system of the Korea Press Foundation, we conducted a content analysis of 2806 articles from 9 Korean daily newspapers during a recent 3-year period from 2015 to 2017. Thematic categories, the types of articles, attitudes and tone, and the number of sources in each article were coded and classified. Results: Many news articles dealt with a diverse range of themes related to cancer, including general healthcare information, the latest research and development, specific medical institutions and personnel, and technology and products, which jointly accounted for 74.8% of all articles. Those thematic categories differed markedly in terms of article type, tone, and the number of cited sources. News articles provided extensive information about healthcare resources, and many articles seemed to contain advertising content. However, the content related to complex social issues such as National Health Insurance did not include enough information for the reader to contextualize the issues properly or present the issues systematically. Conclusions: It can be assumed that the media exert differential influence on individuals through news coverage. Within the present reporting framework, the availability and usefulness of information are likely to depend solely on individuals' capabilities, such as financial and health literacy; this dependency has a negative impact on knowledge gaps and health inequities.

The purpose of this study is to analyze changes in military uniform design according to the type of war in history and to suggest factors to be considered when designing military uniforms. Military uniform in this study has been limited to uniforms of land active soldiers and not only includes battle dress but also bombproof helmets, combat boots and webbing systems. Western military uniform was investigated starting from World War I focusing on the United States, United Kingdom, Germany and the Soviet Union, and Korean military uniform was analyzed starting from the Korean Day of Independence. Historical research, case studies and in-depth interviews were included in the study. World War I was a trench war. Khaki colors began to be used in battle dress, and steel helmets and gas masks were invented. World War II was a full-stale war. Many kinds of uniform were designed with various environments and roles of soldiers in mind, and camouflage was adopted in military uniform. Modern wars were wars of technique. Strong protectors were invented and diverse camouflages were adopted as rifles became increasingly accurate and biochemical weapons started to be used. Korea referred largely to the uniforms of the United States because it lacked both information on war and the financial power to invest in development of military uniforms. Finally, this study presents 5 factors to be considered when designing military uniforms: protection, camouflage, mobile and utility convenience, compatibility and symbolism. Wars of the future are predicted to be information wars utilizing realtime information collected through computers. Therefore new military uniforms with computers, communication devices and strong protective capacities need to be developed. This study aims to provide a theoretical basis for designing military uniforms of the future.

There has not been any scientific analysis on appropriate size of workforce and salary for civilian workers in military so far. Thus, this paper conducted analysis on propriety in employment size of military doctrine researchers using system dynamic methodology based on annual military doctrine workload. Vensim software was mainly used to measure complement of the research group based on data from job analysis. Secondly, a multiple regression analysis was performed to study an appropriate wage for researchers based on their expertise and working condition. The data from twenty public research institutions and twenty eight job positions that are performing similar duty with military doctrine researchers was obtained and utilized to create a salary-estimation regression equation in the analysis. Finally, with cost-benefit analysis method this paper studied financial effectiveness of hiring military doctrine researchers. Contingent valuation method, which has been recognized as one of the most effective methodologies in cost-benefit analysis on intangible value, was utilized to measure benefit of hiring the researchers. The methodology presented in this paper can be applied to measure and improve the efficiency of military organization not only in military doctrine research area but also in several military functional area (military training, logistics, administration, combat development, and combat support).

The aim of this research is to examine patterns of design governance used by Northern European countries to respond to social crises and understand design governance as a tool for sophistication of social services and social integration. Design governance as applied in Sitra of Finland, MindLab of Denmark and the Gulliver project of Germany encourages using design methodology for analyzing and solving problems related to social phenomena based on involvement of the private, public, industrial, and academic groups. Especially, the citizens are actively involved in developing problem-solving ideas and designing new policy with other governance members, rather than simply providing information or one-time participation. In the cases discussed in this study, design governance reduce unnecessary administrative and financial consumption and inconvenience caused by complicated rules, based on field-oriented approach, regional characteristics, pluralism, and respect for diversity. Therefore, future design policy paradigm will need to evolve into concept of policy design and pluralistic monitoring centered on design governance based on participation of private sector to lead policy development, from the current system in which only few officials decide policy.

Recently, the frequency of dealing important information regarding financial services like paying through smart device or internet banking on smart device has been increasing. Also, with the development of smart device execution environment towards open software environment, it became easier for users to download and use random application software, and its security aspect appears to be weakening. This study inspects features of hardware-based smart device security technology. Furthermore, this study proposes a realization method in MTM hardware-based secure smart device execution environment for an application software that runs in smart devices. While existing MTM provides the root of trust function only for the mobile device, the MTM-based mobile security environment technology proposed in this paper can provide numerous security functions that application program needs in mobile device. The further researches on IoT devices that are compatible with security hardware, gateway security technology and methods that secure reliability and security applicable to varied IoT devices by advancing security hardware are the next plan to proceed.
