인천시 강화군 및 옹진군은 접경지역이라는 특수성으로 인해 군사규제 등의 상이한 토지이용규제를 적용받고 있으며, 행정구역상 수도권이라는 이유로 각종 토지이용규제를 중첩적으로 적용받으면서 경제적 낙후와 쇠퇴가 심화된 지역으로 전락하였다. 접경지역을 위한 접경지역지원특별법, 특수상황지역 개발사업 등 상이한 지원 또한 실시되고 있으나 지원사업의 비현실성, 법령의 위계 등의 문제로 여전히 규제로부터 자유롭지 못한 현실이다. 따라서 본 연구는 인천시 접경지역이 갖고 있는 지역적 특성, 즉 접경지역으로서 상이한 토지이용규제에 대한 중첩규제를 이제는 완화해야할 시점이라고 판단하고 본 연구를 실시하였다. 인천시 접경지역에 대한 군사규제의 유연한 해제 및 운영, 수도권정비계획법 규제완화, 문화재 보호구역 등의 완화 등을 통한 전반적인 토지이용규제의 완화가 요구되며, 특히 인천시 접경지역은 접경지역의 특수성과 수도권과의 지역적, 문화적 여건이 상이함을 인정하여 수도권 범위에서 제외시켜 중첩규제로 인한 피해를 최소화해야 할 것이다.

Objectives: At the beginning of the coronavirus disease 2019 (COVID-19) pandemic, some countries imposed entry bans against Chinese visitors. We sought to identify the effects of border shutdowns on the spread of the COVID-19 outbreak. Methods: We used the synthetic control method to measure the effects of entry bans against Chinese visitors on the cumulative number of confirmed cases using World Health Organization situation reports as the data source. The synthetic control method constructs a synthetic country that did not shut down its borders, but is similar in all other aspects. Results: Six countries that shut down their borders were evaluated. For Australia, the effects of the policy began to appear 4 days after implementation, and the number of COVID-19 cases dropped by 94.4%. The border shutdown policy took around 13.2 days to show positive effects and lowered COVID-19 cases by 91.7% on average by the end of February. Conclusions: The border shutdowns in early February significantly reduced the spread of the virus. Our findings are informative for future planning of public health policies.

강화인자 검출법을 이용 X염색체에 P[1ArB]이 형질전환되어 극세포 및 경게세포에서 표시유전자 lacZ를 발현하는 노랑초파리 (EDL 149)를 이용하여 난자형성과정 동안의 경계새포의 분화 및 이동을 조사하였다. 경계세포는 9기 난포의 선단에 위치한 난포 세포로부터 분화하여 9기와 10기에 이동하는 것을 확인하였다. 난소내 \beta -galactosidase의 활성은 우화 후 처음 4일간 급격히 증가하는 것을 확인하였으며 이 시기는 난포 내에서 경계세포가 분화하는 시기와 일치하였다. EDL149의 P[1ArB]삽입의 동형접합체의 난포 내에서 일부 경계세포의 불완전한 이동 또는 지연이 관찰되었다. 감수분열을 진행중인 정소내 세포 및 더듬이에서 확인된 lacZ 유전자의 발현양상은 P[1ArB]의 삽입부위가 난소특이 유전자부위가 아니지만 경계세포 이동의 조절에 역할을 하는 유전자임을 암시한다. 이 형질전환초파리 및 삽입위치 부근의 유전자는 발생중 진행되는 세포이동의 연구에 좋은 모델로 생각된다.

Networking together hundreds or thousands of cheap sensor nodes allows users to accurately monitor a remote environment by intelligently combining the data from the individual nodes. As sensor nodes are typically battery operated, it is important to efficiently use the limited energy of the nodes to extend the lifetime of the wireless sensor network (WSN). One of the fundamental issues in WSNs is the coverage problem. In this paper, the border coverage problem in WSNs is rigorously analyzed. Most existing results related to the coverage problem in wireless sensor networks focused on planar networks; however, three dimensional (3D) modeling of the sensor network would reflect more accurately real-life situations. Unlike previous works in this area, we provide distributed algorithms that allow the selection and activation of an optimal border cover for both 2D and 3D regions of interest. We also provide self-healing algorithms as an optimization to our border coverage algorithms which allow the sensor network to adaptively reconfigure and repair itself in order to improve its own performance. Border coverage is crucial for optimizing sensor placement for intrusion detection and a number of other practical applications.

Radiation Portal Monitors (RPMs) are our primary border defense against nuclear smuggling, but are they still the best way to spend limited funds? The purpose of this research is to strategically compare RPM defense at the border with state-side mobile detectors. Limiting the problem to a comparison of two technologies, a decision-maker can prioritize how to best allocate resources, by reinforcing the border with stationary overt RPMs, or by investing in Mobile Radiation Detection Systems (MRDs) which are harder for an adversary to detect but may have other weaknesses. An abstract, symmetric network was studied to understand the impact of initial conditions on a network. An asymmetric network, loosely modeled on a state transportation system, is then examined for the technology that will maximally suppress the adversary's success rate. We conclude that MRDs, which have the advantage of discrete operation, outperform RPMs deployed to a border. We also conclude that MRDs maintain this strategic advantage if they operate with one-tenth the relative efficiency of their stationary counter-parts or better.

The purpose of the study was to identify dimensions of benefit sought where consumer cross-border online shoppers seek and to examine the effects of the dimensions on expectancy, perceived performance, disconformity and satisfaction with cross-border online shopping. A total of 258 data were gathered and analyzed using SPSS 22.0. The results of the study identified that six dimensions of benefit sought of cross-border online shopping, which were economic-efficiency, convenience, uniqueness, scarcity, superiority and conformity seeking. There were significant effects of economic-efficiency, scarcity and uniqueness seeking on the expectancy, perceived performance, and satisfaction. In addition, consumers were segmented as four clusters classified using benefit sought of cross-border online shopping. The four clusters were labeled as "high interest type", "disinterested type", "unique scarcity type", and "price-first unfussy type". The significant differences were found among the clusters in the research constructs of expectancy and disconfirmation theory. The findings of the study suggested practical and managerial implications.

Cross-border consumer disputes are on the increase as cross-border trade between consumers and businesses continues to grow. Cross-border consumer disputes are difficult to solve, because there are different languages, laws and institutions between the parties. These consumer disputes can be solved more easily by Online Dispute Resolution (ODR) in comparison with utilizing court processes. ODR is a branch of dispute resolution which uses technology to facilitate the resolution of disputes between parties. It primarily involves negotiation, mediation or arbitration, or a combination of all three. In this respect it is often seen as being the online equivalent of alternative dispute resolution (ADR). On 18 June 2013, the new legislation on Alternative Dispute Resolution and Online Dispute Resolution has been published - the "Directive on Consumer ADR and Regulation on Consumer ODR". The new legislation on ADR and ODR will allow consumers and traders to solve their disputes without going to court, in a quick, low-cost and simple way. The United Nations working group for online dispute resolution of cross-border electronic commerce transactions (UNCITRAL Working Group III) has been underway since 2010 to continue its work on procedural rules for ODR.

Since 1993, the number of vivax malaria cases has increased every year in the northern part of the Republic of Korea (ROK). This study was designed to characterize factors related to the reemergence of malaria in the ROK. A total of 21 cases diagnosed in 1993 and 1994 distributed sporadically in the narrow zone along the demilitarized zone (DMZ). Of total 317 civilian inhabitant cases reported in 1994-1997, 287 cases were studied and 80.8% of them resided within 10km from the southern border of the DMZ. The frequency distribution of anti-Plasmodium vivax antibody titers using indirect fluorescent antibody test was compared in three villages in relation with distance from the DMZ. The number of inhabitants with high antibody titers was larger in the village nearest to the border than that in more distant villages. The present results highly suggested that the reemerging vivax malaria start in the border area, most possibly caused by infected mosquitoes which flew across the border. This pattern of transmission repeated year after year.

Cross-border online shopping is an example of non-mobile transnational consumption behavior that has become more popular over the last decade due to the development of technology and transportation. Based on the Theory of Reasoned Action(TRA), this study proposed and tested the hypothesized model that would explain the relationships among consumption beliefs, attitudes toward cross-border online shopping, subjective norms, and purchase intention. Consumption beliefs were measured by global consumption orientation, consumer orientation, and global brand beliefs. In addition, subjective norms included two types: online and offline norms. Descriptive statistics and path analysis were employed for the analysis of the dataset of 174 participants. As a result, the hypothesized model was generally supported. Consistent with the hypothesis, global consumption orientation and global brand beliefs were positively related to positive attitudes toward cross-border online shopping but negatively associated with consumer ethnocentrism. Offline subjective norms positively predicted both the attitudes and purchase intention whereas online subjective norms only predicted purchase intention. The results reflected that TRA was applicable to the intention of cross-border online shopping in a current on-line shopping context. We also discussed the practical applications and limitations of the study.

본 연구는 1986년부터 2008년까지 해외기업을 인수한 284개 한국의 상장기업들을 대상으로 인수기업의 피인수기업에 대한 통제수준이 국제 인수합병(M&A) 성과에 미치는 영향에 대하여 실증 분석하였다. 본 연구의 분석결과, 인수기업의 피인수기업에 대한 통제수준이 국제 인수합병 성과와 음(-)의 관계가 있음을 보여주었다. 또한 피인수기업에 대한 통제수준과 문화적 거리의 상호작용은 국제 인수합병 성과와 음(-)의 관계가 있으며, 피인수기업에 대한 통제수준과 관련형 인수의 상호작용도 국제 인수합병 성과와 음(-)의 관계가 있는 것으로 나타났다. 즉, 본 연구는 문화적 거리가 클수록 또는 관련형 인수일수록 피인수기업에 대한 통제수준은 국제 인수합병 성과에 더욱 부정적인 영향을 주는 것을 보여주었다. 이러한 결과는 국제 인수합병 성과의 결정요인으로서 피인수기업에 대한 통제수준의 역할에 대한 이해를 높이는 것은 물론, 문화적 거리 및 관련형 인수와 국제 인수합병 성과간의 관계에 대한 설명에 있어서도 피인수기업에 대한 통제수준을 고려함으로써 기존 연구들을 보완해 주고 있다.
