The purposes of this study were to explore the techniques of neutralization on unethical customer return behaviors, examine the differences in the neutralizations by customer characteristics, and examine the relationships of neutralizations with customer ethics, anomie, and impulsive behaviors. A total of 609 questionnaires were analyzed. Four factors including denial of injury/victim, condemning the condemners, denial of responsibility, and appeal to higher loyalties were extracted from the neutralization techniques. The neutralization techniques were not different by customer characteristics, but were negatively related with customer ethics and positively related with anomie and impulsive behaviors. The results indicate that the neutralization techniques are appropriate to understand unethical customer return behaviors in the Korean retail settings.

온라인 악성댓글에 대한 폐해는 지속적으로 증가하고 있다. 많은 선행 연구들은 악성댓글에 대한 중화가 핵심적인 선행 요인임을 확인해왔다. 중화는 이론적으로 일곱개의 다차원 개념으로 구성되어 있으며 일탈행위의 종류에 따라 중화요인의 유의성이 다르게 나타난다. 본 연구는 일탈행위 연구에서 다차원의 중화 기술 요인들을 실증한 것과는 다르게 악성 댓글 연구에서는 중화기술을 단일 차원으로 살펴보았다는 사실에 주목한다. 한편, 일탈행위에 대한 중재자의 역할은 일탈행위 억제에 기여할 수 있지만 악성댓글 연구에서의 중재 의도에 대한 연구는 상대적으로 부족한 상황이다. 상호보완적인 두 개의 연구로 구성된 본 연구는 악성댓글 작성의도와 중재 의도에 대한 관련 요인들을 발견하고자 하였다. 연구결과, 본 연구는 악성댓글 작성자가 비난자에 대한 비난과 책임의 부정 중화기술을 활용 한다는 것을 발견하였다. 또한, 상대방과의 정서적 공감이 악성댓글 중재 의도에 중요한 영향을 준다는 사실을 발견하였다.

Despite of continuous efforts to crack down on piracy using penalties and regulations, this unauthorized piracy market is still enormous. Since the moral hazard about this phenomenon is pervasive and continually upsets the major intellectual property markets, an alternative plan is required. The purpose of this study is to provide an objective insight for factors that affect people's digital video piracy behavior. The following two research propositions were the focus: what psychological factors affect piracy behavior and how are these factors related to one another? In order to accomplish the research aims, we reviewed literatures on the current state of piracy in South Korea, characteristics of digital contents, studies on criminal psychology and behavioral theories. Previous research in the fields of criminal theory indicated that neutralization, a form of rationalization, would help explain digital piracy intentions. Thus, this study developed a model that explains effects of neutralization techniques and tested the possibility of an integrated model with other behavioral theory such as TPB and TIB. Empirical results of the study(368 sample collected) showed that all the factors in TPB including Attitude to Piracy(+), Subjective Norm(-), Perceived Behavioral Control(+) had a significant impact on Piracy Intention. Moreover, two neutralization techniques, Condemn the Condemners(+) and Appeal to Higher Loyalties(+), had a significant effect on Piracy Intention. In addition, Past Behavior had strong impacts on Attitude(+), Perceived Behavioral Control(+) and Piracy Intention(+). In terms of Expected Profit, it had an impact on Attitude to Piracy positively. These findings suggest implications for protecting the current intellectual property markets, with many stakeholders in movies and media industries. There are some limitations as followed: first, the study did not consider other neutralization techniques, low level of deterrence and the other expected results despite the possibility of their effects. Second, the study needs improvements through longitudinal research because the cross-sectional research could not rule out the alternative explanations.

The high virulent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus that emerged in China at the end of 2019 has generated novel coronavirus disease, coronavirus disease 2019 (COVID-19), causing a pandemic worldwide. Every country has made great efforts to struggle against SARS-CoV-2 infection, including massive vaccination, immunological patients' surveillance, and the utilization of convalescence plasma for COVID-19 therapy. These efforts are associated with the attempts to increase the titers of SARS-CoV-2 neutralizing Abs (nAbs) generated either after infection or vaccination that represent the body's immune status. As there is no standard therapy for COVID-19 yet, virus eradication will mainly depend on these nAbs contents in the body. Therefore, serological nAbs neutralization assays become a requirement for researchers and clinicians to measure nAbs titers. Different platforms have been developed to evaluate nAbs titers utilizing various epitopes sources, including neutralization assays based on the live virus, pseudovirus, and neutralization assays utilizing recombinant SARS-CoV-2 S glycoprotein receptor binding site, receptor-binding domain. As a standard neutralization assay, the plaque reduction neutralization test (PRNT) requires isolation and propagation of live pathogenic SARS-CoV-2 virus conducted in a BSL-3 containment. Hence, other surrogate neutralization assays relevant to the PRNT play important alternatives that offer better safety besides facilitating high throughput analyses. This review discusses the current neutralization assay platforms used to evaluate nAbs, their techniques, advantages, and limitations.

최근 무선트래픽 수요가 폭발적으로 증가하면서 셀룰라 무선망에서 이를 효율적으로 지원하기 위한 스몰셀 연구가 활발히 수행중이다. 본 논문은 스몰셀 구현의 가장 큰 걸림돌인 다중셀 간섭을 효율적으로 해결하기 위한 간섭상쇄 기법에 대해 연구하였다. 각 사용자의 메시지가 기지국 혹은 릴레이를 통하여 전달되는 경우, 무선채널의 시변특성을 이용한 간섭상쇄 기법을 제안하였다. Amplify-and-forward (AF) 에 기반한 기존 접근방식은 잡음증폭 특성으로 인하여 신호대잡음비가 낮은 영역에서는 심한 성능열화를 보였다. 본 논문은 최근 개발된 compute-and-forward (CF) 에 기반한 간섭상쇄를 제안하여 이러한 문제를 해결하고 신호대잡음비가 작은 영역에서 전송율을 크게 개선하였다.

The clinical experience with the activated clotting time[A.C.T.] for the control of heparin and protamine therapy during cardiopulmonary bypass in 40 patients between April, 1987 and September, 1987 is reviewed retrospectively. All of patients used with cold blood potassium cardioplegia for myocardial protection under standard cardiopulmonary bypass, priming and perfusate techniques respectively. This study was divided into 2 groups of patients followed by cardiopulmonary bypass time. Twenty patients, within 60 minutes of cardiopulmonary bypass time[group A] were compared with twenty patients, from 60 to 120 minutes of cardiopulmonary bypass time[group B]. Using blood cardioplegia for myocardial protection, Author observed wide variation of A.C.T. in individual response to initial heparinization[2mg /kg] and no requirement of additional heparin during cardiopulmonary bypass until 120 minutes. Total heparin amount during cardiopulmonary bypass was not related to body weight and body surface area in the both groups. After cardiopulmonary bypass, amounts of protamine for neutralization of heparin were more required in group B.

By applying the newly developed techniques of polymer impregnated concrete (PIC) severely deteriorated and low quality concrete can be restored to an adequate structural material. Early deterioration of concrete causes severe problems for bridge deck concrete, pavement concrete for highways and airports, hydraulic structures and buiilding structures. Deterioration has its orgin in cracks on concrete surface, scaling of spalling due to freezing and thawing, neutralization of concrete, penetrations of water, salt, and calcium chloride. The objective of this study is to develope the new surface impregnants and strengthening techniques for them. It is found that the new impregnants and strengthening techniques developed in this study can retian the charecteristics of the existing concrete and decrease deterioration, and also increase durability, chemical resistance, strength, stiffness and ductility of the existing concrete.

The COVID-19 pandemic, triggered by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has not only impacted human health on a global scale but also raised concerns about the vulnerability of a wide array of animals that are in close contact with humans. Particularly, the potential for infection and the subsequent immune response in domestic pets such as dogs and cats remain largely unexplored under natural living conditions. In this study, we have undertaken the task of detecting and tracking the presence of antibodies against SARS-CoV-2 in a small cohort of household pets-specifically, two dogs and two cats. Employing techniques such as the indirect ELISA and plaque reduction neutralization tests, we observed that the neutralizing antibodies against SARS-CoV-2 in these animals were maintained for a duration of up to six months following their initial positive test result. This duration mirrors the antibody response documented in human cases of COVID-19, suggesting a comparable post-infection immune response timeline between humans and these domestic animals.
