Across two experiments, this study provides support for the concept that money and time are marked by psychologically distinct constructs. As temporal distance increases, preferences are more likely to be based on the value associated with a high-level construal of options than the value associated with a low-level construal of options. That is, as potential contributors are asked to donate later, high-level featured resources (i.e., time) take focal precedent over low-level ones (i.e., money) in judging preference for donation methods. This study also found that the match effect between temporal distance and construal-level holds only when the level of attitude toward NPO is relatively favorable. However, donation intention is enhanced under mismatch conditions when the level of attitude is less favorable. That is, when potential contributors hold relatively less favorable attitudes toward the NPO, those who are requested to make an expediting decision of donation are more likely to have higher intention to donate with a high-level construal resource. This study attributed the finding to the shift of people’s focal resource through their level of attitude toward the NPO. Unlike the previous research, which focused mainly on how temporal distance influences individuals’ construal levels to result in different donation behaviors, this study investigates the relationship between donation resources and temporal distance. The results from the research provide empirical evidence that temporal distance can have impact on individuals’ preference of the types of donation resources. Given that the features of donation resources can be related temporal distance, this research can shed light on how temporal construal theory can be used in charitable-giving contexts. Additionally, while considerable number of temporal construal studies have investigated the impact of the match effect on the attitude toward a brand, this study explores the role of attitude toward the organization on the interaction effect of temporal distance and construal levels. The findings from this study can provide an opportunity for better understanding of temporal construal theory.

In this study, a relatively effective process is used to sterilize Escherichia coli on the surface of micro-sized calcium citrate powder using nitrogen and argon as process gases in a low-temperature vacuum plasma treatment. The purpose of this study is to confirm and to introduce the effectiveness of homogeneous surface treatment for the sterilization of fine inorganic powder by the rotatable low-temperature RF plasma system designed by ourselves. The results of the test using 3M petrifilm showed that there were no remarkable spots in the case of the surface of plasma treated powder, whereas the untreated powder showed many blue spots, which indicating that the E. coli was alive. After 5 days, in the same samples, the blue spots were seen to be larger and darker than before, while the plasma-treated powder showed no changes. The results from FE-SEM analysis showed that the E. coli was damaged and/or destroyed by reactive species generated in the plasma space, resulting in the E. coli being sterilized. Furthermore, the sterilization effects according to the selected parameters (N2 and Ar; flow rate 30 and 50 sccm) adapted in this study were mutually similar, regardless of such different process parameters, and this indicates that homogeneous treatment of powder surfaces could be more effective than conventional methods. Therefore, the plasma apparatus used in this study may be a practical method to use in a powerful sterilization process in powder-type food.

As digital media empowers consumers to initiate and participate in the marketing communication process more than ever, the current study aimed to investigate whether consumer motivations to use media are associated with the concept of psychological distance. Using a general population sample (N = 291) in U.S., psychological distances of four media platforms (i.e., television, mobile, laptop, newspaper) are compared and the relationship between media usage motivations (perceived ease of use, perceived usefulness, usage frequency, emotional attachment, and compatibility) and psychological distance are examined. Results indicate that psychological distance varies across media types and the relationship between psychological distance and media usage motivations is mostly positive.

본 시험은 우리나라에서 발생하는 푸른곰팡이병균의 종의 빈도와 발병환경 및 방제법을 구명코져 실시하였다. 시험결과 Trichoderma koningi, T. lignorum, T. glaucum과 미동정의 1종등 4종의 병원균이 분리되었고 이들의 빈도는 각각 와 이었다. 푸른곰팡이병균은 감자배양액, 왁스만배양액과 리차드배양액에서 생육이 잘 되었으며 중성-염기성배지에서는 생육이 불량한 반면 산성에서 생육이 왕성하였으며 최적산도는 pH4였다. 양송이 수확기간 중 재배사내의 온도는 내외 일 때 본명의 발생이 적었고 수량이 많으며 이상에서는 본병의 발생이 격심하였다. 푸른곰팡이병균은 복토흙 소독시 에서 60분, 혹은 에서 30분간 열처리하므로서 완전히 사멸하였고 퇴비 후발효 과정에서도 사멸되었다.
