This paper analyzes how and why household debt distribution by the householder age has changed over the past decade both in Korea and the US. Data shows that the proportion of household debt held by younger households has decreased, while that held by older households has increased. Empirical analysis shows that a change in the demographic distribution of householders is the main driving force that has shifted the household debt distribution. Given that demographic aging is an inevitable trend, the proportion of household debt held by older households is also expected to increase. Therefore, the Korean government must preemptively prepare for the household debt problem, especially for debt held by older households, by strengthening macro-prudential policies, preventing asset price deflation, restructuring household debt contract structures, and reforming labor market inflexibility.

한국에서의 고령화는 아직 걱정할 단계는 아니지만 고령화의 속도가 지나치게 빠르게 진행된다는데 문제가 있다. 인구의 절대규모는 2030년의 52,160 천명에서 정점을 이루다가 감소하여 2050년에는 2005년 수준인 48,121천명으로 감소하며, 핵심근로계층인 25-54세의 인구는 저출산과 고령화로 인하여 이미 2012년부터 감소하는 것으로 예측되었다. 고령화는 불가피하게 노동력의 부족을 초래하게 되며, 이는 한 번도 경험해보지 못한 상황에서 정책 수단들을 세워나가야 한다. 본 논문에서는 몇 가지의 대안을 제시하였다. 첫째, 인구규모 자체의 감소를 예방하기 위한 것으로 국가 지원의 보육체계를 포함하는 출산장려정책을 제시하였으며, 둘째, 노동력 절대규모의 감소라는 현실적 상황에서 고용률로 측정된 노동시장의 참여를 증대시킬 수 있는 방안을 제시하였다. 먼저 정년 연장형의 임금피크제를 포함하는 고령자 및 출산의 기회비용을 낮추어 여성의 노동시장 참여를 촉진하는 방안을 제시하였다. 결론적으로 고령화는 피할 수 없는 상황이며, 지속가능한 균형성장이라는 틀에서 문제해결에 접근해야 한다.

Purpose - Domestic cooperatives tend to increase during the establishment of cooperatives and gradually through the basic law of social needs. However, only cooperatives' qualitative grow this secured without blessings, and their quantitative growth through government support is questionable. The purpose of this study is to analyze the agricultural cooperatives established through the Distribution System Cooperatives Basic Law, which was enacted in January 2012. Subsequently, establishing agricultural cooperatives was done briskly. However, cooperatives established rapidly after the founding of the Basic Law encountered problems. Research design, data, and methodology - To assess the performance of selected agricultural cooperatives, data were analyzed using the methodological Analytic Hierarchy Process (AHP) approach. The AHP is a set of systematic procedures to hierarchically analyze the elements of any problem. Using a survey on expertise, a series of comparative determinations of each pair is performed to evaluate the relative strengths and the strengths of the impact between elements within the hierarchy. A survey was conducted on 10 small agricultural cooperatives using AHP analysis for the examination. The purpose of such research and analysis is to recommend a direction for future policies aimed at small agricultural cooperatives. Result - This study applied three types of policy evaluation criterion, including market expansions, organizations, and cooperative projects, and 12 types of small agricultural cooperative policy measures. Market expansion policies for agricultural cooperatives are classified into four categories: school meals, direct transactions, shopping malls, and wholesale markets. Organizational policies for agricultural cooperatives are classified into four types: existing sales channel management, education, preventing free riding, and enlarging members. Cooperative project policies in agricultural cooperatives are classified into four policy areas: cooperation between cooperatives, community contribution, joint businesses, and government links. In this paper, the growth priority in agricultural cooperative policies is analyzed by applying policy evaluation criteria on the basis of a survey on expertise. The priorities of the policy program are also analyzed using a decision analytic hierarchy process. The results indicate that market expansion is the most important policy evaluation criterion therefore, improving direct transactions, school meals, management of existing sales channels, and shopping malls are crucial policy measures. In contrast, the cooperation of cooperatives, expansion of union members, and cooperation with the government were found to have low priority. Conclusions - Agricultural cooperatives should develop plans as follows. Small agricultural cooperatives need to secure school meals and direct transactions for market expansion, restructure marketing strategies to manage existing sales channels, and, finally, increase education and training for sustainable organizational development. This study has the following limitations. Because the subject of the investigation is a new cooperative, determining its sustainable growth is difficult. Therefore, through analysis and a continuous study of cooperatives, future research is expected to show that modifying the direction of agriculture cooperatives is necessary.

This study focuses on the ideas that Chok-Du-Ri(족두리)ㆍHwa-Gwan(화관) are mentioned a substitute preventing abuses of luxury mood by Gache(가채) as the sharpest social problem at that time. First, the origin of Chok-Du-Ri(족두리) was introduced from Ko-Ko-Gwan(고고관) of Mongo(몽고) in Korea dynasty, then was linked to Chosun. That is, Ko-Ko(고고) started from headgear reflecting spiritual view of the northen people, its size was getting smaller passing through Ming(명) dynasty, its essential decoration changed and it carried out Jeon-Ja(전자) remaining decoration nature by real accessories, then it might be descended to Chosun. Second, Hwa-Gwan(화관) is very different from Nanaec(난액) of Chosun Dynasty Records, rather Jeonia, the original form of Chok-Du-Ri, is more similar to it. Third, its decoration like color, jewel, pattern etc influenced wishes of this life like sex, prosperity, glory, longevity, blessing, wealth and fame. Fourth, Chok-Du-Ri(족두리) was restored a substitute for Gache(가채), it was accessory for preventing luxury life, besides it was modeled from headgear in China, Chosun people had it. It is worthwhile as it was based on Chosun Sinocentrism(조선중화주의) in the latter period of Chosun and made it the fruit of that age. Moreover, in those days Qing(청) society accepted the advanced culture and institutional profit of Qing(청) actually, social mood is that home and overseas policy was corrected in many parts, Chok-Du-RiㆍHwa-Gwan were mentioned a substitute of Gache, symbol of luxury. It shows one part of Practical Thougth that abolishes vanity and affectation and makes useful profits in the latter period of Chosun.

교통사고가 발생하면 사고 차량은 주변 차량에게 안전 메시지를 멀티 홉으로 브로드캐스트 해야 한다. 하지만, 순수한 플러딩 방식을 사용하면 잦은 충돌로 인해 통신 지연이 유발되고 이로 인해 연속 추돌 사고 예방이 어렵다. 본 논문에서는 이러한 문제점을 해결하기 위해 속도에 따른 이웃 노드의 수를 t-분포를 이용하여 추정하고 이를 백오프 알고리즘에 적용한다. 그리고 멀티채널을 이용하여 이웃 노드 개수의 수집 채널과 데이터 채널로 분리하여 통신 지연을 예방하는 MAC 프로토콜을 제안한다. 결과적으로, 기존 기법보다 제안된 프로토콜이 프레임 수신율이 10% 이상 개선되었음을 확인하였다.

최근 인터넷을 통해 개인정보 유출사례가 빈번히 발생하고 있으며, 한번 유출된 개인정보는 회수 변경이 어렵고, 명의도용 사기 등 제3의 범죄로 까지 이어지고 있어 국가차원의 대책 마련이 요구된다. 현재 각 포털사(社) 쇼핑몰 등 인터넷 사업자는 회원 가입시 개인정보를 무분별하게 수집하고 있으며 제대로 된 보안관리가 이루어지지 않고 있는 실정이다. 이러한 상황은 시간이 지날수록 해커가 공격할 수 있는 취약 요인의 수만 증가 시킬 뿐이며 보안 관리 범위도 통제할 수 없게 된다. 또한 국내 외 해커들은 금전적 이득을 얻기 위해 개인정보를 선호하고 있어 향후에도 개인정보 유출 사고는 지속 증가할 것으로 예상된다. 이에 본 논문에서 인터넷 회원가입을 위해 수집하는 개인정보 보안 관리 실태를 살펴보고 유출된 개인정보를 인터넷에서 재사용할 수 없도록 하는 공인인증서 기반 개인 인증체계 개선 모델을 제안하기로 한다.

The consumption of natural cheese in Korea has dramatically increased since 1997. However, most of the cheeses consumed in Korea are imported. Thus, surplus milk has accumulated in Korea. To solve this problem, the Ministry of Agriculture, Food and Rural Affairs established a policy to create a farmstead dairy industry. Although the law governing the industry was established in 2016, food safety guidelines have not been prepared. Milk and cheese are prone to contamination with mycotoxins such as aflatoxin M1 and ochratoxin A, antibiotic residues such as penicillin and tetracycline, and pathogenic bacteria including Listeria monocytogenes, Escherichia coli, Salmonella, and Staphylococcus aureus. L. monocytogenes infections have a very high mortality rate; hence, special attention should be paid to preventing contamination of milk and cheese with this organism. To ensure the microbiological safety of farmstead dairy products, the HACCP model has been used. However, this model is not suitable for current processing environments of farmstead dairy products because of the small size of the operations. In addition, scientific data on the microbiological safety of farmstead dairy product are limited and are urgently needed.
