Coping with the problems of school violence, weapon and drug abuses, 'zero tolerance policies' have been adopted in the United States since the 1980's. Authorities have been securing the safety and learning-friendly environment of the school, imposing predetermined penalties on any case of school violence or disruption. It is reported that the school violence rate drops accordingly. However, the policies are criticized for their rather escalating effect due to severe punishments on minor offenses, evidencing no effectiveness worthwhile. As alternatives, 'graduated systems of discipline' meeting minor misbehaviors with less severe consequences or 'early response model' are suggested, without abandoning those main rules of zero tolerance policies. Recently Korean government tries to take charge of school violence, issuing some nation-wide measures such as 'the Comprehensive Measures to Stop School Violence'. This article analyzed major principles and changes of the zero tolerance polices of US case, to induce some policy suggestions for the validity of Korean government's measures implemented under the understanding that "little bullying" is also a "crime" to disclose all school violence.

This study reviews articles published in the Review of Social & Economics Studies and presented at many research conferences organized by Korean Association for Political Economy(KAPE). The purpose of this review is to retrospect such research activities of KAPE and to make a step forward to relevant research on Korean Economy. Considering current economic depressions and the crisis of academic science in general, the responsibilities of researchers as a economist are heavier than ever. To break through these difficulties, we have to inspire and organize research activities at KAPE level above all things. At the individual level, we should attend objective analysis and propose alternatives to Korean economy in the lights of reform and progress viewpoint.

Inlet hammershock is the critical loads condition for designing the inlet duct structure of a fighter. The sudden flow reduction in engine compressor causes inlet hammershock with high pressure. The traditional method was used to combine extreme conditions (maximum speed, sea level altitude, and cold day) to analyze this compression wave inlet hammershock pressure. However, after the 90s there have been papers that presented the probabilistic approach for the inlet hammershock to achieve the appropriate design pressure. This study shows how to analyze the inlet hammershock pressure by making practical use of the Republic of Korea Air Force real flight usage data under probabilistic approach and then analyze approximately 30% decreased inlet hammershock pressure compared with the traditional valve.

The purpose of this paper is to systematically evaluate the relationship between cancer health literacy and cancer screening behaviors using global data. Following the preferred reporting items for systematic reviews and meta-analyses review guidelines, full-text articles published on PubMed, CINAHL, Embase, and Cochrane Library were reviewed until 31 January 2021. The reference lists of all selected studies have been also included. The cancer health literacy and cancer-screening behaviors of the participants aged ≥18 years were assessed. Seventeen studies that met the inclusion criteria were included. The cancer screening behaviors included mammograms, clinical breast cancer examination, Papanicolaou test, colonoscopy, and PSA screening. Eleven studies revealed a statistically meaningful relationship between the cancer health literacy and cancer screening behaviors. Further research should focus on developing effective interventions and guidelines on cancer health knowledge. The research scope of all areas of cancer health literacy and cancer screening behaviors should be extended to improve the cancer screening rates and public health.

In this research, design and fabrication of marine repeater capable to extend communication coverage in monitoring system of fishing gear automatic identification, which is one of implementation method of the real-name electric fishing gear system declared by Ministry of Oceans and Fisheries in 2016, is reported. The proposed marine repeater is fabricated in a form of RF repeater with interference cancellation system (ICS), which can cancel the oscillation due to feedback signal between service antenna and link antenna. In design process, we secure the isolation of 30 dB between service antenna and link antenna. It is confirmed that when the level of feedback signal into repeater input be lower of 15 dB than repeater gain, error vector magnitude due to oscillation can be lower than the performance criterion of 6%, from the test verification. It is expected that the service coverage will be extended by applying the developed marine ICS RF repeater into marine IoT network including monitoring system of fishing gear automatic identification.

According to a survey by the Korea Tourism Organization in 2018 and 2019, traveling to places recorded in TV programs or influential videos has become an important travel trend and several studies show that watching a travel program improves the intention to visit the places featured on the program. This study designed a travel program-linked data service that provides additional information on the places and events to the viewers of the travel program. Specifically, the additional information of the travel program was defined in a formal manner by dividing it into places and events, and a method of exposure of the additional information conformed to the contents of the program was designed. We also devised an international standard DVB-based data transmission method that provides the additional information to data services appropriately in time for program broadcasting. This study is significant in that it tested new applications of data services for travel programs.

This study aimed to identify and analyze the attributes of FoMO, and to provide basic data for the intervention of FoMO in cancer patients. In order to confirm conceptual attributes, antecedents, and consequences by applying the conceptual analysis method of Walker & Avant (2010), 82 previous studies published from 2004 to 2021 were analyzed. The conceptual attributes were relative deprivation, social exclusion, lack of sense of belonging, lack of interaction with others, negative emotions, and the antecedents were a sense of alienation when you miss the flow or when excluded from activities and the desire to connect with others. The consequences of this were increased emotional distress, triggering negative emotions such as depression and anxiety, and decreased life satisfaction and self-esteem. The attributes of these FoMO were also confirmed in cancer patients. Based on this, it is necessary to develop an effective intervention program to improve FoMO in cancer patients.
