Tsunami Event

This paper investigates whether it is possible to determine shelter locations and congestion spots at the time of an event, by resorting to the recently anticipated use of mobile space data at the time of a disaster. This study focused on the earthquake and the resulting tsunami that occurred off the coast of Fukushima Prefecture on November 22nd, 2016. We verified whether it is possible to identify congestion spots and shelter locations by comparing with the results of a questionnaire survey conducted in a previous study on evacuation behavior at the time of the occurrence of earthquakes and tsunamis. As a result, we found that it is difficult to determine evacuation behaviors from the data, as raw mobile space data extracted several hours after the tsunami event only gave information on where spots’ populations ordinarily converge to. We were able to determine the locations where populations gather by taking into consideration time-based differences between the raw data obtained. It, however, proved difficult to obtain a good determination of congestion spots.

Evacuation Behaviors

The torrential rain (named “the July 2018 heavy rain”) from June 28 to July 8 in 2018 resulted in tremendous human and property damage. There were 237 deaths and 7,173 cases of flooding above the floor level. During the torrential rain, the low rate of evacuation behavior of residents in the affected area was also a problem. The Okayama prefecture conducted a mail survey with residents that suffered housing damage caused by the torrential rain (valid sample n = 3,765). The survey measured what residents’ awareness and knowledge were of flooding before the torrential rain, residents’ prediction of flooding and choice and reason of evacuation behavior during the emergency heavy rain warning and the evacuation order (emergency). This study analyzed the determinants of residents’ evacuation behaviors during the torrential rain with the survey data. The results indicated that, although most residents were aware of hazard maps before the torrential rain, few predicted flooding. Most residents were aware of the evacuation shelters and had a prior evacuation plan. However, some residents made no attempt to evacuate, even when their houses were damaged. During the emergency heavy rain warning, feeling a sense of crisis was an important factor to promote evacuation behavior. And, during the evacuation order (emergency), the majority of those who took actual evacuation behaviors was those who were approached by public sectors such as the fire department and the police. Moreover, residents’ judgment based on scientific information such as hazard maps and prediction of flooding before the torrential rain had little effect on evacuation behavior during the emergency heavy rain warning and the evacuation order (emergency). Therefore, the study indicates the importance of approaching residents’ affective decision-making, instead of relying on rational decision-making, to promote evacuation behavior when people are in unusual situations.

AbstractThe determination of spatial ambit of the coastal State jurisdiction is fundamental for ocean governance and the same applies to the Arctic Ocean. In this regard, a question arises how it is possible to delimit marine spaces where the jurisdiction of two or more coastal States overlaps. Without rules on maritime delimitation in marine spaces where the jurisdiction of coastal States overlaps, the legal uses of these spaces cannot be enjoyed effectively. In this sense, maritime delimitation is of paramount importance in the Arctic Ocean governance. Thus, this study will examine Arctic maritime delimitations by comparing them to the case law concerning maritime delimitation. In so doing, this study seeks to clarify features of Arctic maritime delimitations.

The measurement of terminal productivity is the issue of extreme importance to both terminal owners and management and customers. As the sector of transport is highly intensive in terms of investments into the infrastructure, the productivity of a terminal may play a crucial role in competing with other terminals. Productivity is defined in terms of inputs and output. The majority of the available studies, wherein this issue is addressed, are generally focused on the determination of functional dependence between inputs and output using the method of regressive analysis. The present article provides an insight into the Data Envelopment Analysis method as a tool for measuring productivity. This technique enables a rather accurate evaluation of terminal productivity by means of comparative analysis, which, in fact, appears to be the only feasible alternative in cases where statistic data required for performing regressive analysis is lacking.

The objective assessment of the development level of information and communications technology (ICT) in education can support the government in formulating and implement ICT policies. The article first introduced the Entire-Array-Polygon (EAP) indicator method and then designed an evaluation indicator system which containing five first indicators and 31 secondary indicators. Finally, using the questionnaire survey data of 13 cities in Province W as an example, the EAP indicator method was used to carry out on the evaluation of ICT development level. The study drew the following conclusions: EAP indicator method can objectively assess the development level of ICT; the overall development level of ICT in the 13 cities in Province W is average and above, and most of them are level II. When using the EAP indicator method to assess the development level of ICT, experts do not need to determine the indicator's weight. Also, this method presents the evaluation results more concisely and intuitively, so it can be promoted as an essential method of evaluating on the development level of ICT in education.

The ever-increasing need for in-depth analysis and quantification of the national power, in particular ‘hard’ and ‘soft’ power-generating factors as well as difficulties in identifying a comprehensive and effective method for scientific determination of the national power, have given rise to research in the indicated scientific issues within this article. The presented considerations aim to define the assumptions for a descriptive sub-model that would enable a comparison of Poland’s power in the economic sphere (which is a component of the non-military sphere) with the power of selected European countries. The research hypothesis is that, among the variety of descriptive variables in the economic sphere of the national power, there is a subset of mutually independent variables, at the same time strongly correlated with the national power, which make it possible to define assumptions for the sub-model of the national power. The steps of the research procedure were carried out using the method of system analysis (multi-criteria comparative analysis) and statistical analysis. The research activities undertaken have shown that the factors that are strongly correlated with the national power in the economic area of the European countries adopted for the analysis are: dynamics of industrial production, private sector credit flows and economic freedom index. The comparative analysis carried out demonstrates that the greatest increase in the economic power in the analysed period took place in Germany (0.68). Slightly smaller growth was recorded in the Czech Republic (0.62) and Poland (0.60), while the lowest value of increase was in Romania (0.23). The conducted qualitative comparative analysis of the economic power of selected European countries allowed to conclude that the independent variables identified are crucial for the formation of the economic power of the analysed countries. At the same time, a fairly strong position of the Czech Republic and Poland in relation to the economic power of Germany was found. The performed quantification of the economic power of the European countries provides a basis for the correct determination of changes in the power distribution of political units, assessment of the power and resources held by the state.
