2017년부터 2018년까지 전북지역 오디 생산용 뽕나무에 발생하는 주요 해충의 발생 양상과 유기농업자재에 의한 뽕나무이 방제 효과를 조사하였다. 부안과 익산지역을 중심으로 수확 전 발생하는 주요 해충은 뽕나무이, 미국흰불나방, 뽕나무명나방, 노린재류, 꽃매미 6종이었으며 수확 후에는 미국흰불나방, 뽕나무명나방, 총채벌레, 미국선녀벌레, 노린재류 등 5종이 발생하였다. 또한 오디 생산용 뽕나무 재배시 가장 문제가 되는 병해충인 균핵병과 뽕나무이를 동시에 친환경적으로 관리하기 위해서는 데리스 추출물(데리스 90%) 250배와 황토유황 500배를 혼합하여 처리하는 것이 방제효과 97.6%로 효과적이었다. 선발된 유기농업자재에 효과적인 처리시기는 4월 상·중순이며, 7일 간격으로 3회 방제하면 94% 이상의 방제효과가 있고 약해도 발생하지 않아 유기농업자재를 이용한 뽕나무이의 친환경방제가 가능할 것으로 판단되었다.

최근 안전한 먹거리에 대한 관심 제고와 고품질 대추 생산에 대한 관심 급증으로 친환경적인 해충방제법의 필요성이 높아지고 있다. 친환경적 해충방제를 위하여 비가림하우스 별 방충망을 설치하여 해충방제 효과와 과실 생육을 조사하였다. 시험에 사용된 방충방 규격은 각각 25, 18, 6mesh로 대추나무잎혹파리, 장님노린재, 복숭아심식나 방의 차단효과를 보았다. 대추나무잎혹파리의 경우 피해엽율이 1.2%, 10.8%, 14.3%, 무처리구는 15%였으며 장님노린 재의 경우 피해눈율이 6.9%, 5.8%, 20.41%, 28.2%였고, 심식나방은 피해과율이 0.0%, 1.0%, 0.0%, 32.0%로 나타났다. 방충망처리에 따른 대추생육은 처리구와 무처리구에서 차이가 거의 없었다. 대추재배농가의 방충망 도입이 해충 방제에 효과가 큰 것으로 판단되며 문제가 되고 있는 세가지 해충을 모두 방제하기 위해서는 25mesh로 처리하는 것이 가장 효과적인 것으로 판단된다.

Schizandra chinensis is one of the local special crops grown in Mungyeong, more than 70% of Gyeongbuk area. Scirtothrips dorsalis(Hood) are the most damaging pests among the insects that occur in the Schizandra chinensis, mainly affecting fruit quality, yield and quality. Therefore, it is necessary to study how to reduce the damages by establishing efficient forecasting method and pesticide control system for the Scirtothrips dorsalis(Hood) occurring in Schizandra chinensis. Scirtothrips dorsalis(Hood) was surveyed with yellow sticky traps from April to September in the Mungyeong area. Scirtothrips dorsalis(Hood) has the highest density in July, beginning in early May, and then again in September. Therefore, the suitable time to control the Scirtothrips dorsalis(Hood) is in late May, early July, and mid August. Three species of pesticides(Spinetoram WG, Emamectin benzoate EC, Chlorfenapyr EC) registered in Scirtothrips dorsalis(Hood) were treated three times at the suitable time, as a result of the treatment, a high effect of 92% more.

고추 비가림하우스에서 에어포그 시스템을 이용한 무인방제 효과를 평가하기 위해 본 시험을 수행하였다. 에어포그 시스템과 동력분무기를 이용한 관행방제의 약제살포 시간은 동일한 약량으로 살포하였을 때 처리 간에 차이가 없었으나, 에어포그 시스템으로 1/2약량을 살포하였을 때는 관행방제 보다 살포시간이 약 50% 줄었다. 약제부착 능력을 감수지로 조사하였을 때, 고추 생육초기와 중기에는 모든 처리에서 약제 부착이 우수 하였지만, 생육후기에는 관행방제의 약제 부착이 에어포그 시스템보다 균일하지 않았다. 처리별 총채벌레 살충률은 관행살포 90.0%, 에어포그 시스템 90.8%, 에어포그 시스템 1/2약량이 83.5% 로 유사한 방제효과를 나타내었다. 이러한 결과로 에어포그 시스템은 고추 비가림하우스 내에서 노동시간과 약제 살포량을 줄이면서 총채벌레를 효과적으로 방제할 수 있을 것으로 판단된다.

Background: Stroke patients usually have arm weakness, which affects trunks and arms. Objective: To investigate the effects of paretic side and non-paretic side arm training on trunk control and upper limb functions. Design: Randomized Controlled Trial (single blind). Methods: Twenty patients with stroke in hospital were enrolled in the study. Twenty subjects were randomly assigned to paretic side arm training group (PATG, n = 10) or non-paretic side arm training group (NATG, n = 10). Trunk impairment scale (TIS) was used for trunk control, and box and block test (BBT) was used for upper limb function. Training was conducted for 4 weeks. Results: PATG showed significant difference in TIS (static balance, dynamic balance, coordination, total score) and BBT. NATG showed significant differences in static balance, and dynamic balance and total score except for coordination and BBT. PATG also showed a more significant difference in BBT and coordination and total score than NATG. Conclusions: The arm training performed on the paretic side are more effective than those performed on the non-paretic side in improving both upper limb function and trunk control in stroke patients.

To improve the performance of carbon nanofibers as electrode material in electrical double-layer capacitors (EDLCs), we prepare three types of samples with different pore control by electrospinning. The speciments display different surface structures, melting behavior, and electrochemical performance according to the process. Carbon nanofibers with two complex treatment processes show improved performance over the other samples. The mesoporous carbon nanofibers (sample C), which have the optimal conditions, have a high sepecific surface area of 696 m2 g−1, a high average pore diameter of 6.28 nm, and a high mesopore volume ratio of 87.1%. In addition, the electrochemical properties have a high specific capacitance of 110.1 F g−1 at a current density of 0.1 A g−1 and an excellent cycling stability of 84.8% after 3,000 cycles at a current density of 0.1 A g−1. Thus, we explain the improved electrochemical performance by the higher reaction area due to an increased surface area and a faster diffusion path due to the increased volume fraction of the mesopores. Consequently, the mesoporous carbon nanofibers are demonstrated to be a very promising material for use as electrode materials of high-performance EDLCs.

Laminate composites composed of 0.95Pb(Zr0.52Ti0.48)O3-0.05Pb(Mn1/3Sb2/3)O3 piezoelectric ceramic and Fe-Si-B based magnetostrictive amorphous alloy are fabricated, and the effect of control of the areal dimensions and the thickness of the piezoelectric layer on the magnetoelectric(ME) properties of the laminate composites is studied. As the aspect ratio of the piezoelectric layer and the magnetostrictive layer increases, the maximum value of the ME voltage coefficient(αME) increases and the intensity of the DC magnetic field at which the maximum αME value appears decreases. Moreover, as the thickness of the piezoelectric layer decreases, αME tends to increase. The ME composites exhibit αME values higher than 1 Vcm−1Oe−1 even at the non-resonance frequency of 1 kHz. This study shows that, apart from the inherent characteristics of the piezoelectric composition, small thicknesses and high aspect ratios of the piezoelectric layer are important dimensional determinants for achieving high ME performance of the piezoelectric-magnetostrictive laminate composite.

2017년 경북지역은 약 700ha 이상의 면적에서 미국선녀벌레의 피해를 입었다. 그 중 600ha의 피해면적이 떫은감 주요 생산지인 청도군에서 발생하였다. 미국선녀벌레의 효율적인 방제를 위해 2018년 5월 상순에 침투이행성 약제를 토양에 처리하여 약충이 부화하기 전감나무 수체 내 약제를 이행시켜 방제효과를 조사하였다. 토양입제처리의 방제효과 조사를 위하여 토양입제 단독처리(5월 상순), 경엽살포 단독처리(6월 중순), 토양입제(5월 상순) 및 경엽살포(6월 중순) 체계처리를 비교하였다. 조사결과 토양입제 단독처리 시 약제처리 후 약 70일 이상 90%이상의 방제효과가 지속되었고, 경엽살포 단독처리 시 약제처리 후 약 2주 동안 90%이상의 방제효과를 보인 뒤 방제효과가 감소하였다. 또한 토양입제 및 경엽살포 체계처리 시 약제처리 후 약 70일 동안 95%이상의 높은 방제효과를 보였다.

This study investigated number of eggs, hatch rate, toxicities and LT (lethal time) values of Culex pipiens and Aedes albopictus using Aquatain™(Aqua mosquito film). Aquatain™ is a covering agent applied on the surface of water for the control of larva and pupa of mosquito. It forms molecule layer on the surface of the water to lower the surface tension of the water, to prevent flooding of the larva of the mosquito larvae, or to suffocate by obstructing breathing. Cx. pipiens and Ae. albopictus larvae observed 99.9% and 1% larvicidal effect after 24h, respectively. However, both mosquito pupae were showed 100% mortality after 24 h. The AMF™ was treated with three doses (0.5, 1, 2 folds) to observe the LT value in larvae and pupae stages of Cx. pipiens and Ae. albopictus. The LT values of Ae. albopictus pupa was similar regardless of dose, but the LT value of Cx. pipiens pupa decreased as the dose increased. However, Ae. albopictus larvae showed 18.6 folds longer LT90 time than Cx. pipiens larvae. Both species mosquito showed statistically significant differences in the number of eggs laid and hatch rate at recommended dose. Therefore, Aquatain AMF™ may be used to control mosquitoes, although the activity varies depending on the species of mosquito.

This study is intended to look into the effect of construction safety supervision system on risk control and reduction. To achieve this, a survey was carried out to 114 companies in construction, ordering, contract and management. The overall findings were as follows. The effect of construction safety supervision system on risk control and reduction showed that factors of supervision system, supervision cost and supervision method had a positive effect on risk control and reduction. And their perception of the introduction of safety supervision system in construction sites according to process showed that there was a difference between them according to the field of ordering, contract and supervision. There was the biggest difference between owner and contractor in double supervision system, but no difference between them in the perception of risk reduction. These results show that all ordering, contract and supervision are positively needed for the introduction of construction safety supervision. This means that there is a difference between owner and contractor in the perception of process according to system operation. All companies agree to system improvement by the settlement of safety supervision system for the prevention of safety accidents and safe construction, but the systematic complement of safety supervision is the burden of contractor. And there is a big difference between owner and contractor in the perception of responsibility and concern for cost burden.

Introduction In the past study, the relationship between the power structure of marketing and research and development (R&D) and NPD performance was not consistent (Atuahene-Gima & Evangelista, 2000; Engelen & Brettel, 2012; Li & Atuahene-Gima, 1999, 2001). The inconsistency may result from each study in different industrial contexts. It reflects every NPD project faces different environmental uncertainties. Furthermore, we adopt the external control perspective to glue power structure and NPD performance under a certain external environment together. Therefore, this paper tends to fulfill the gap of prior study, and the main objective of this research is to investigate whether the power structure of marketing and R&D functions have different linear relationships under the different level of environmental uncertainty. A NPD team is like a cross-functional organization that the NPD team is composed of multiple functions, and it has independent budgets. The members in the team will allocate their limited resources like budgets or positions to respond environments and to maximize profits. Theoretical Development When a NPD team faces the high market uncertain situation, marketing function can gather more resources because of its own power. Thus, R&D members in a NPD team may have less determination in the process of NPD. Even though they create a new product, marketing specialists make most decisions in the NPD team. According to function’s contribution argument, the more contribution of a certain function to the NPD process, the more positive related to the new product success (Atuahene-Gima and Evangelista, 2000; Atuahene-Gima and Luca, 2008; Li and Atuahene-Gima, 1999). Therefore, the current study proposes the hypothesis1 described below: H1: Market uncertainty will strengthen the relationship between power structure leaned to marketing and NPD successes. When a NPD team encounters the fast technological change situation, R&D function has more resources because of power. New product teams, however, usually have scare resources, so that another important function like marketing will have fewer resources than R&D function. Thus, marketers in a NPD team may have less determination in the process of NPD. The marketers may have some influence on launch stage like sales and promotion or distribution channels (Hsieh et al., 2008), but R&D specialists make most decisions in a NPD team. Therefore, the current study proposes the hypothesis2described below: H2: Technological uncertainty will strengthen the relationship between power structure leaned to R&D and NPD successes. Eisenhardt and her colleagues indicated that the organizations in high velocity environments have better performance when they decentralize the power structure (Eisenhardt, 1989; Eisenhardt and Bourgeois, 1988). They also described that this firm tended to introduce a new product line, and that its channel partners were fighting with each other by price wars but the dominant marketing function did not have enough time to perform its regular job. To maintain its power and resources, the dominant function may highlight its importance, so it will withhold external information and enable other members to perceive the external environment what dominant function expect them to perceive. When organizations find a lot of environmental changes, it is too late. Therefore, in the beginning organizations adopted decentralized power structure, and allocated resources equally. The members in organizations may not snatch resources, so they may not take political actions also. For the specialists in new product development team, they could not control their unique knowledge to withhold the information and to satisfy their own self-interests. Therefore, the relationship between marketing and R&D power distribution in a NPD team and new product financial performance is weakened in high velocity environments (Eisenhardt and Bourgeois, 1988). The hypothesis3 in the current study is below: H3: the relation between the power distribution in new product development teams and new product development successes is inverted U curve under the high technological and market uncertainty. Coping environment could rely on top manager’s backgrounds like marketing, technology or finance (Hambrick and Mason, 1984). To maintain the status of the dominant function, the dominant function will lead the organization to identify the important problems related to its function. In order to ensure keeping their power, moreover, the dominant function could institute some regulations or create norms. According to resource dependence perspective, if an organization has higher the formalization of power, the dominant function could gather more resources because of legitimacy. Further, the higher formalization of power may strengthen the relationship between power distribution and performance. Thus, our hypothesis 4 is below: H4: Under the higher formalization of power in a new product development team, the stronger relationship between the marketing and R&D power distribution and new product performance than under the lower degree of formalization of power situation. Research Design The current study used questionnaire survey and purposive sampling method to collect data. In order to eliminate the bias of common method variance (CMV), this study conducted multiple sources including project managers, the member charging marketing, and the member charging R&D to administrate questionnaires differently. In order to avoid selection bias, this study, moreover, asked the informants select the most recent new products developed and launched for minimum of twelve months. We sent three types of questionnaires to project managers, the member charging marketing, and the member charging R&D respectively. The current study sent questionnaires to 112 firms, and 69 firms are returned. The response rate is 61.61%. At new product level, there are 207 new product projects, and 100 firms are returned. The response rate is 48.31%. We also do tests of bias due to nonresponse which were conducted by using a comparison of early to late respondents’ all variable means (Armstrong & Overton, 1977). No evidence of a bias was found. The current study applied Moorman’s (1995) operationalization of new product performance is that the extent to which the product has achieved the objective of market share, sales, return on assets, profit margin, and return on investment during the first 12 months of its life in the marketplace. These items were used a 7-point Likert scale where 1 was “low” and 7 was “high”. This research adopted Homburg et al. (1999) scale to measure the power structure between marketing and R&D functions by using 100-point constant-sum scale for each NPD issue, and other previous studies also used issue-based perceptual power scale (Enz, 1989; Hinings et al., 1974; Pfeffer, 1981; Verhoef and Leeflang, 2009). The current study adopted Jaworski and Kohli’s (1993) scale to measure market and technological turbulence. The items were used a 7-point Likert scale where 1 was “extremely disagree” to 7 was “extremely agree”. In order to rule out other effects, we controlled industrial category, firm age, the number of marketing and R&D members involved in the NPD process, environmental hostility. Result and Conclusion The first finding is that under low market uncertainty and high technological uncertainty, balance of power structure tends to swing to the side of R&D function, and achieve better in NPD performance. Take IC design of High-tech industry as an instance, NPD project ends to perform better when the balance of power structure swing to the side of R&D function. The second finding is that under high market uncertainty and low technological uncertainty, NPD formalization helps to strengthen the relationship between marketing and NPD performance. Take frozen dessert in the food industry or leisure and sports fabrics in the textile industry as examples, formalization of NPD process can help marketing-driven NPD projects perform better in market. These findings advanced the understanding of the relationship between the power structure of marketing and R&D and NPD performance, rather than focusing on a single function, marketing or R&D. Furthermore, examining the relationship between the power structure of marketing and R&D and NPD performance in different environment uncertainty situations explained the inconsistency of the relationship between the power structure of marketing and R&D and NPD performance in past studies. Finally, this research conditionally supported the moderating effect of NPD formalization on the relationship between the power structure of marketing and R&D and NPD performance, and this exploration never been found.
