Landslides pose significant threats to many countries globally, yet the development and implementation of effective landslide early warning systems (LEWS) remain challenging due to multifaceted complexities spanning scientific, technological, and political domains. Addressing these challenges demands a holistic approach. Technologically, integrating thresholds, such as rainfall thresholds, with real-time data within accessible, open-source software stands as a promising solution for LEWS. This article introduces LandScient_EWS, a PHP-based program tailored to address this need. The software facilitates the comparison of real-time measured data, such as rainfall, with predefined landslide thresholds, enabling precise calculations and graphical representation of real-time landslide advisory levels across diverse spatial scales, including regional, basin, and hillslope levels. To illustrate its efficacy, the program was applied to a case study in Medellin, Colombia, where a rainfall event on August 26, 2008, triggered a shallow landslide. Through pre-defined rainfall intensity and duration thresholds, the software simulated advisory levels during the recorded rainfall event, utilizing data from a rain gauge positioned within a small watershed and a single grid cell (representing a hillslope) within that watershed. By identifying critical conditions that may lead to landslides in real-time scenarios, LandScient_EWS offers a new paradigm for assessing and responding to landslide hazards, thereby improving the efficiency and effectiveness of LEWS. The findings underscore the software's potential to streamline the integration of rainfall thresholds into both existing and future landslide early warning systems.

This paper investigates the effectiveness of Real-Name System on Internet, which has been applied to some Internet service provider bulletin boards in Korea. The goal of the Real-Name system on the Internet is controlling expression of slanderous or abusive language. The effectiveness of the regulation is dependent on the people's perceptions and attitude toward to the legislation. This empirical study examines the antecedents that affect the perceptions and attitude toward the regulation. Further, we investigate the relationships among variables such as internet public sphere participation, attitude to the regulations, and intention to choose detours. Results of regression analysis show that the younger and the more progressive individuals are, the more they oppose the implementation of the law. Also, it was found that people who have more political interest and participate more actively in public sphere via internet, tend to oppose the law. Structural equation models reveal that participation in online public sphere drives negative attitudes about the regulation. In addition, people with negative perceptions about the law tend to choose the detours such as 'cyber asylum' and 'service asylum'.

Although Korean government has implemented size-dependent policy, so called "the designation of SMEs-suitable industry", promoting SMEs growth, our understanding in the effectiveness of the policy is limited. We investigate the effect of the policy on SMEs performance in food product and beverages industry, which accounts for the majority in the SMEs-suitable industry. From the perspective of sales, profitability, and R&D intensity, which is regarded as indigenous effort for growth, we find the heterogeneity in the effectiveness of the policy across the sub-sectors in the industry. However, overall the policy does not significantly contribute to the growth of sales, profitability, and facilitation of R&D activity for indigenous innovative efforts of SMEs. Our study advances the theoretical discussion on the effect of the policy with the disaggregated level of analysis, i.e, sub-sector level. Our findings also contribute to the resolution of social and political conflicts between pros and cons of the policy. Our study suggests that policy makers should develop more sophisticated policy that incorporate the specific characteristics of individual sub-sectors. They also need to invest more resources in enhancing the effectiveness of the policy and accelerating SMEs innovative efforts.

Since the seminal publication of Joseph Nye's Soft Power, soft power became the central concept to public diplomacy. However, over-emphasis on soft power, which is still controversial, deterred academics from producing valuable knowledge that can be applied to practices in the field. Soft power is a cause and effect at the same time and thus it makes systematic analysis almost implausible because it is not only a tool for successful public diplomacy, but it is a result of successful diplomacy. This study aims at offering a theoretical framework linking soft power and public diplomacy by including various factors that may affect the outcomes of effective public diplomacy. This theoretical framework assessing the effectiveness of public diplomacy will make it possible to explore how and when new public diplomacy was adopted in a certain country and examine hard and soft power resources. The model also includes political system variables such as ideas and values, institutions, governance, leadership, and communication system, which are expected to influence public diplomacy effectiveness rather than soft power itself. The model yields the effectiveness of public diplomacy by assessing outcome and impact relative to input and output that are applicable to practices. The model is expected to enable both quantitative and qualitative studies generating possible propositions from the model with some preliminary outcomes of comparative case studies.

Struggle refers to the process of overcoming various difficulties for a goal. The spirit of struggle is a positive attitude and reaction reflected in the process of struggle. Cultivating the spirit of struggle of college students is the call of the new era. In essence, the cultivation of the spirit of struggle is a process of learning, which is in line with Bandura's Observation Learning Theory(Bandura, 1977):Attention, Maintenance, Reproduction and Motivation. The cultivation of College Students' spirit of struggle in the new era is also a learning process of enriched experience. It is necessary to cultivate the spirit of struggle into the soul of college students and make it become a habit of students. Moreover, it is crucial to carry out adaptive transformation of Bandura's observation learning theory. By studying the mechanism of the spirit of struggle of college students, taking innovation and entrepreneurship education as a means, and aiming at cultivating the connotation of President Xi's thought on socialism with Chinese characteristics for a new era, this paper constructs the AIST model for cultivating the spirit of struggle of college students in the new era. This model includes online learning acceptance platform(Acceptance), classroom experience stimulation platform(Inspiration), iterative training solidified platform (Solidification), and competition practice transfer platform(Transfer). The purpose of this model is to provide a practical way for universities to fulfill the fundamental task of moral education and cultivate qualified socialist builders and successors. The number of students using the online learning acceptance platform ranked the first among that of the similar courses in China; The classroom experience stimulation platform and the iterative training solidified platform support each other, with an effective rate of 97%; The competition practice transfer platform has realized the continuous growth of the number of awards won in competitions for three years. The direction of future efforts is to establish the external mechanism of the spirit of struggle, to ensure the effectiveness of classroom experience and iterative training, to cultivate teachers with coaching skills, and to accurately measure the transformation point of external and endogenous motivation.

The purpose of this study is to verify that several theories explaining the determinants of welfare expenditure is applied to the family policy expenditure and to find out if there' re unique determinants of the family policy expenditure. We analyzed the data (OECD 14 countries for 1980~2005) by pooled time series analysis. As for industrialization theory, female labor force participation rate has positive effect on family policy expenditure while population under 15-year children has negative effect, which refers to the demand of family policies is that of female workers, not children's. Power resource theory is applied to the determinants of family policy expenditure as those of welfare expenditure. Women's political & economic empowerment has partly positive effects on family policy expenditure, which is the evidence of the effectiveness of feminist theory. In the institutional theory, we verified the effect of policy legacy but couldn't find out the crowding-out effect. The theoretical implication of this study is the empirical verification of the theories explaining the determinants of welfare expenditure being applied to the family policy expenditure. We also suggested the political and institutional foundation to effectively respond to the new social risks in spite of budget constraints, which can be a policy implication.

Purpose: The purpose of this paper is to analyze the demand and supply of advanced practice nurses and suggest alternative benefit strategies in the Korean national health insurance. Methods: A revised demand & supply model was used to estimate the excess supply of APNs, and policy making process and key actors in the Korean health insurance were considered to develop a political approach to the APN issue. Results: The social demand for APNs is currently estimated to be less than 50% of its supply and the APN education program fell into difficulties in recruits. No reimbursement mechanism for APN's services in the national health insurance has given no economic incentive to hospital managers who have monopsony power in nursing labor market, which has caused the demand shortage of APNs in hospital industry. Payment for APN's services recognized as one of the most significant strategies to booster the social demand for APN's services should be carefully designed and implemented in the national health insurance. In line with this, key actors in health insurance policy decision-making include government, national assembly, labor unions, NGOs, civic groups, medical associations, and academia. Conclusion: The basic researches for APN's activities and cost-effectiveness analysis in clinical settings are required to support the strategies aforementioned. Constructing a policy network among key actors is able to make the payment strategy feasible, which will increase the socal demand for APNs.

Since the middle of the 70s, the countries with the marine resources declared the exclusive water zone of two hundred miles. As a result, our country lacked many foreign fishing grounds. This awakened our perception of fishing grounds. The fishing ground is an important factor in the economical effectiveness of fisheries. The fishing ground must have the following basic conditions. 1. It must be the place the fishery resources inhabit and wander. 2. Their catching or aquaculturing must be possible by the technical methods. 3. It must have economic worth in the management. The fishing ground that achieves the above basic conditions is affected by the following factors. This is the factor of the fishing ground location. A. Natural factor 1). Suitable climate 2).Abundant resources 3). Good quality of the sea-bottom 4). Not to be pollutted area B, Economic factor 1). Be adjacent to fishing port and fisheries market 2). Good working conditions 3). Be abundant of economical resources C. Social factor 1). Be possible to work legally 2). Be permitted in the political relations 3). Be acquainted with the customs of foreign countries The fishing ground location is mainly affected by the natural factor of the above factors. The abundance of resources depends on the natural resources. The resources in the fishing ground have the cycle of developing period, maturing period, and decaying period according to the fishing efforts. The point that we sustainably yield the maximum of fishery resources is the changing point of maturing period and decaying period. We call this point MSY, so the resources of fishing ground should be managed by the MSY. Therefore, when we select the fishing ground location. We should judge the natural factor, the economic factor and the social factor synthetically according to the situation and environment, so we can achieve the efficient management.

As online game addiction of youth becomes a serious social problem, various regulations restricting their game play have been introduced. However, it is considered that forced shut-down, selective shut-down, and other regulations have no effect, and theoretical debates about the necessity of regulations also continue. Therefore, this study theoretically re-examines the necessity of youth game regulations by the discussion on domestic and international policy trends and existing research. In order to confirm empirical evidence of the effectiveness of regulations, this study compares and analyses the change of youth's game play time and patterns before and after the regulations. According to the results, the effect of the regulations is inadequate so this study proposes reasonable improvement ways of them through convergent approach including legal, political, and technological perspective.
