Virus-like particles (VLPs) are similar to pathogenic viruses, but because they have no nucleic acid, they have excellent safety and immunogenicity and are used as a good vaccine material. However, in the selection of various structural proteins of pathogenic viruses to form VLPs, all expression systems consume a lot of time in common. Among them, the baculovirus expression system causes additional time consumption to construct the recombinant baculovirus. Therefore, there is a need for a system that can rapidly determine the structural proteins required for effective VLP production. This study aims at solving this problem by constructing a BmNPV inducible expression platform through the construction of vectors induced by BmNPV. The platform was evaluated for overexpression using EGFP. We also confirmed the formation of virus-like particles through overexpression of canine parvovirus structural proteins.

농업용 무인멀티콥터를 활용한 방제면적은 수도작은 물론 밭작물에서도 방제 범위가 확대되고 있다. 밭작물은 작물의 형태가 다양하여 비행속도, 살포높이 등을 최적화하는 연구가 필요하다. 본 연구에서는 배추, 대파, 고추에서 발생하는 나방류에 대하여 무인멀티콥터의 살포 높이에 따른 방제효과를 확인하였다. 살포된 약제가 작물에 부착되는 정도를 조사한 결과, 배추는 2m, 대파는 3~4m, 고추는 모든 높이에서 비슷한 부착정도를 보였지만, 전체적으로 부착량이 적고 불균일 하였다. 살포 높이별 방제효과는 작물별로 각각 배추(9~10엽기)는 2m높이, 고추(약 1.2m)는 2~3m, 대파(약 60cm)는 2, 3, 4m 각각 비등한 방제효과를 보였다. 각각의 작물모두 경엽처리 대비 약효가 미흡하였으며, 고추는 4m높이 살포시 방제효과가 현저히 낮았다.

The popularity of succulents as ornamental plants has increased in recent years. This is primarily because of their unique geometric shapes, which form a rosette, coupled with their ability to retain high levels of moisture. These features make ornamental succulents suitable as landscape plants as they can withstand extreme conditions and as potted plants for indoor spaces as they require minimal watering. Appropriate propagation techniques are important to increase production rates and plant quality in the shortest time possible. These ornamental plants may be propagated in various ways, both sexually, via seeds, and vegetatively, through a number of methods, such as stem cuttings, leaf cuttings, and micropropagation. In this review, methods for the propagation of ornamental succulents are described, including post-propagation care and management. Propagation aspects on which limited information is available are also highlighted. Potential areas for research required to produce data to further improve techniques, conservation, and rapid propagation efforts are discussed.

Co-branding is defined as a marketing strategy in which “two brands are deliberately paired with one another in a marketing context such as in ads, products, products placements, and distribution outlets” (Grossman 1997, p. 191). Prior research suggests that the crucial key to the success of co-branding is perceived fit including both product category fit and brand image fit. The product category fit is the relevancy of product category between partner brands about co-branding product or brand. For example, “Apple” collaborated with “Nike” to make a smart watch for sports activates. The brand image fit is about how the images (such as luxury image, young and fun image) fit between the partner brands. Prior co-branding research shed light on the effects of perceived fit between co-branding partner brands. Nevertheless, the findings of prior research have been limited to the two types of perceived fit. This research introduced the new-type of perceived fit called “sensory fit” In the current study, the sensory fit is defined as the perceptual congruency between partner brands’ sensory factors such as color, shape, size, and so on. Still, the sensory fit in context of co-branding are yet to be fully investigated by academic research. To fill the gap in the literature, we designed two experimental studies to better understand how the sensory fit affects the evaluations of co-branding. In study 1, we manipulated the partner brands’ sensory attributes (i.e., pronunciation of brand name and shape of brand logo). The results showed that the sensory fit significantly influences consumers’ response to co-branding. That is, a significant interaction (sensory fit × product involvement) was observed, suggesting that participants showed more positive attitudes on the evaluation of co-branding in the low-involvement product (i.e., mug) condition. However, the same pattern was not observed in the high involvement product condition (i.e., laptop). In Study 2, we replicated the findings of Study 1 and used letter style of brand name to manipulated the sensory fit. Findings showed a significant main effect of sensory fit again. Interestingly, the sensory fit was found in the high-involvement and hedonic products condition only. In sum, our findings suggest that the sensory fit should be considered as it predicts the success of co-branding strategy.

Currently, the Korea Atomic Energy Research Institute (KAERI) is planning to build the Ki-Jang Research Reactor (KJRR) in Ki-Jang, Busan. It is important to safely dispose of low-level radioactive waste from the operation of the reactor. The most efficient way to treat radioactive waste is cement solidification. For a radioactive waste disposal facility, cement solidification is performed based on specific waste acceptance criteria such as compressive strength, free-standing water, immersion and leaching tests. Above all, the leaching test is important to final disposal. The leakage of radioactive waste such as 137Cs causes not only regional problems but also serious global ones. The cement solidification method is simple, and cheaper than other solidification methods, but has a lower leaching resistance. Thus, this study was focused on the development of cement solidification for an enhancement of cesium leaching resistance. We used Zeolite and Loess to improve the cesium leaching resistance of KJRR cement solidification containing simulated KJRR liquid waste. Based on an SEM-EDS spectrum analysis, we confirmed that Zeolite and Loess successfully isolated KJRR cement solidification. A leaching test was carried out according to the ANS 16.1 test method. The ANS 16.1 test is performed to analyze cesium ion concentration in leachate of KJRR cement for 90 days. Thus, a leaching test was carried out using simulated KJRR liquid waste containing 3000 mg·L-1 of cesium for 90 days. KJRR cement solidification with Zeolite and Loess led to cesium leaching resistance values that were 27.90% and 21.08% higher than the control values. In addition, in several tests such as free-standing water, compressive strength, immersion, and leaching tests, all KJRR cement solidification met the waste acceptance or satisfied the waste acceptance criteria for final disposal.
