This study aims at shedding light on two questions: 1) how livelihood strategies hired by heterogeneous farm households differ and in what aspect, and 2) would the strategy change over time or remain identical across farm types? Using 2013-2017 Farm Economy Survey panel data, we divide the sample farms into 4 sub-groups based on income level and sources. Key findings are as follows. First, regardless of farm types, strong path dependency has been observed. That is, lots of farms are likely (enforced) to maintain the livelihood strategies, accounting for why many farms fail to response to market and/or policy signals. Second, along with compounding risks, farms are more vulnerable to specific sorts risks. Third, based on the findings, we made policy suggestions.

The outbreak of COVID-19 has had a huge impact on human life. The World Bank group (WBG) has stated that 2020 is the worst year since World War II for economic growth. An epidemic of an infectious disease such as COVID-19 is classified as a "social disaster" by law. The social disaster caused by COVID-19 puts certain industries, occupations and vulnerable groups at risk of exclusion and isolation. This paper intends to examine the fluctuations in the consumer price index in the cultural, sports and tourism sector before and after the onset of COVID-19. In addition, it predicts the consumer price index by sector until December 2021 and reveals its implications.

In the 21st century, information collection and information provision based on digital informatization and intelligent automation are emerging as one of the social problems in the society for the elderly and the vulnerable groups in the welfare society including the disabled, and various methods are being studied to find realistic alternatives. Among these factors, the problem of the elderly living alone is emerging as the most serious, and as a realistic approach to solve some problems by applying information devices, it is a monitoring system using the Internet of Things(IoT). The need for an optimized system is emerging. In this study, the state of the elderly and the elderly living alone can be measured remotely by applying IoT technology. We present the research cases of a Breathing Sensor-based Smart Monitoring System that is used as a smart information system and used as a monitoring system for the elderly and infirm when it is identified as deceased through state detection

We live in a digital age. Smartphones are used by everyone from children to the elderly. And many smart devices are pouring out and changing our daily life a lot. However, even in the development of this digital age, there are some marginalized groups. There are also those who are reluctant to expose their information in the digital age. They have difficulty making reservations on their smartphones, using payment systems, logging into the site using various authentication and verification procedures, and entering and leaving buildings. We still carry most IDs, seals, certificates, etc. in physical form. Those who use smartphones are enjoying the convenience of the times. However, among the underprivileged, the desire to pass everything with only one device is growing. In this study, the most suitable smart band model was proposed by collecting the Delphi survey and the opinions of the general public. Future research is required to improve practical usability and utility by developing cheaper and more convenient models.

As digital advertising continues to dominate the advertising industry and experience substantial growth, associated criminal activities such as advertising fraud and brand safety risks have become increasingly prevalent. Despite the severity and extent of these crimes, the response in Korea has been lackluster, often perceiving them merely as losses in advertising expenses incurred by corporations. However, it is important to note that these issues have direct repercussions on the end-consumer in the form of increased prices for goods and services. Furthermore, illegal and intrusive advertisements not only cause inconvenience to the viewer, but may also indiscriminately target cognitively vulnerable groups, such as children and the elderly, with the intention of manipulating advertising metrics and artificially inflating performance indicators. In this study, we aim to explore the concept and significance of advertising fraud and brand safety, and to evaluate the current measures taken in the Korean market. Additionally, we will delve into the implications of related policies and emphasize the necessity of digital advertising literacy in addressing these issues.

우리나라의 아고산대는 기후변화에 지역적 취약성을 띄는 지역으로, 아고산대의 산림식생은 기후변화에 따른 영향을 관찰할 수 있는 중요한 기초지표 중 하나이다. 본 연구는 지리산 아고산대의 기후변화 취약수종 분포지의 산림식생을 대상으로 하여 식물사회학적 식생 유형 및 희귀-특산식물 분포 특성에 대해 구명하였다. 2015년 3월부터 10월까지 37개소에서 식생조사를 실시하였고, 식물사회학적 식생유형 분류를 통해 종조성을 파악하고, 종의 우점도를 파악하기 위해 중요치를 이용하여 식생유형별 층위구조를 분석하였다. 그 결과 식생유형분류체계는 8개 종군유형과 5개의 식생단위로 구분되었다. 산림청 지정 특산식물은 9분류군, 희귀식물은 17분류군이 출현하였고, 북방계식물의 비율은 41.2%이며, 식생단위별 해발고도가 증가함에 따라 희귀-특산식물도 함께 증가하는 것으로 나타났다. 중요치 분석 결과, 구상나무는 모든 식생단위에서 평균상대우점치가 높게 나타났다. 또한 층위별로 보았을 때 식생단위 1을 제외한 단위들에서는 신갈나무, 당단풍나무 등의 수종과 경쟁관계에 놓여 있는 것으로 판단되었다. 본 연구의 결과는 기후변화로 인한 아고산대 산림식생의 변화를 이해하기 위한 기초 자료 뿐만 아니라 식생학적 접근을 통한 장기 모니터링의 기초지표로 활용될 것으로 판단되었다.

PURPOSES : The purpose of this study is to analyze the characteristics of the weight values of evaluation items by traffic safety project type. METHODS : In general, a large-scale investment in projects such as the traffic safety project requires economic analyses to be performed in advance. However, there is an argument for considering special characteristics of the traffic safety project. Therefore, this study conducted characteristic analysis of the weight values of evaluation items. The analysis consisted of two steps. The first step was hypothesis verification using analysis of variance (ANOVA). In this process, the authors examined whether the weight of evaluation items is the same regardless of the traffic safety project type. Based on the first step's results, the authors proceeded to the second step. The objective of this step was to analyze how different the weight values are by traffic safety project type using an analytic hierarchy process. RESULTS : According to the ANOVA test results, the benefit to cost ratios have different weight values based on traffic safety project type at the 0.01 significance level. The policy evaluation items, such as the plans connection, resident opinion, and regional equity, also showed the same results except that the result for the related plans connection was statistically significant at the 0.05 level. Based on the first step's result, the AHP analysis in the second step showed that the traffic safety projects for vulnerable users and pedestrians have very low weight values in economic evaluation factors compared with other safety project types. The weight values for vulnerable users and pedestrians were 0.29 and 0.26, respectively, in economic evaluation items. On the other hand, the weight values for other safety project types were around 0.6. Among the policy evaluation items, resident opinion showed a higher weight value than other factors, such as connection and regional equity items. CONCLUSIONS : The social and economic impact of a traffic safety project varies by project type and project characteristics. Although the economic approach is overarching and a reasonable methodology is applied for large-scale projects, it should be noted that the safety issue, especially for transportation of vulnerable uses, requires a non-economical approach. Based on the analysis results, this study suggests that the priority of the projects should be determined by separating them into independent assessment groups depending on their characteristics.

유엔세계관광기구(UNWTO)는 1991년 관광약자를 위한 '모두를 위해 접근 가능한 관광'을 선언하며 관광향유권의 실천을 권고하였다. 보건복지부(2019)에 따르면 관광약자인 등록장애인은 전체 인구 대비 5.1%이며, 2025년 65세 이상 노인 인구는 20.3%까지 증가할 것으로 전망된다. 특히 65세 이상 노년층 장애인의 비율이 지속적으로 증가하면서 맞춤형 정책의 필요성이 제기되고 있다. 본 연구는 이러한 필요성을 바탕으로 관광 취약계층을 고려한 유니버설 디자인 관광지의 공간적 특성을 파악하였다. 이를 위해 서울시 행정동(425개)을 공간적 범위로 설정하였으며, 시간적 범위는 2020년으로 설정하였다. 연구방법으로는 먼저, LM 검증을 통해 적합한 공간 모형을 추정한 후, 적합한 모형을 적용한 공간회귀분석을 실시하였다. 분석 결과, 유니버설 디자인 관광지의 공간적 특성은 관광약자가 이용 가능한 시설로 인증된 유니버설 인증업소 수, 외식업소 수, 버스정류장 수와 정(+)의 영향관계를 갖는 것으로 나타나 유니버설 디자인 관광지가 밀집된 행정동에 유니버설 인증업소와 외식업소, 버스정류장이 다수 분포하는 것을 확인하였다. 이러한 분석 결과는 향후 관광향유권의 도모를 위한 정책과 국내의 유니버설 디자인 정책 개선에 시사점을 제공할 수 있을 것으로 판단된다.
