Recently, as the management environments are changing rapidly and the uncertainty is becoming larger, the needs of internal control for management and IS become stronger. In order to construct a new internal control system for IS, it is necessary to evaluate the former research of the system. This study emphasizes the importance of effective internal control system, presents a conceptual framework for the preceding factors to consider, and verifies empirically the framework. This study sets the organization citizenship behavior, IS innovation resistance, and IT capability from the viewpoint of Socio-Technical system as the preceding factors for the effectiveness of internal control system. A research model, affecting the above factors on IS capability as a mediating variable of the internal control effectiveness for the use of IS, is set up. PLS-Graph 3.0 is used to verify the model. We found that the internal control effectiveness have affirmative effect on information capability, a surrogate variable of the IS effectiveness and a mediation effect is meaningful.

Drug-resistant tuberculosis (TB) is still a major threat worldwide. However, recent scientific advances in diagnostic and therapeutic tools have improved the management of drug-resistant TB. The development of rapid molecular testing methods allows for the early detection of drug resistance and prompt initiation of an appropriate treatment. In addition, there has been growing supportive evidence for shorter treatment regimens in multidrug-resistant TB; and for the first time in over 50 years, new anti-TB drugs have been developed. The World Health Organization has recently revised their guidelines, primarily based on evidence from a meta-analysis of individual patient data (n=9,153) derived from 32 observational studies, and outlined the recommended combination and correct use of available anti-TB drugs. This review summarizes the updated guidelines with a focus on the medical management of drug-resistant TB.

Background: Increasing the slip resistance of floor surfaces would be desirable, but there is a lack of evidence on whether traction properties are linearly correlated with the topographic features of the floor surfaces or what scales of surface roughness are required to effectively control the slipperiness of floors. Objective: This study expands on earlier findings on the effects of floor surface finishes against slip resistance performance and determines the operative ranges of floor surface roughness for optimal slip resistance controls under different risk levels of walking environments. Methods: Dynamic friction tests were conducted among three shoes and nine floor specimens under wet and oily environments and compared with a soapy environment. Results: The test results showed the significant effects of floor surface roughness on slip resistance performance against all the lubricated environments. Compared with the floor-type effect, the shoe-type effect on slip resistance performance was insignificant against the highly polluted environments. The study outcomes also indicated that the oily environment required rougher surface finishes than the wet and soapy ones in their lower boundary ranges of floor surface roughness. Conclusion: The results of this study with previous findings confirm that floor surface finishes require different levels of surface coarseness for different types of environmental conditions to effectively manage slippery walking environments. Collected data on operative ranges of floor surface roughness seem to be a valuable tool to develop practical design information and standards for floor surface finishes to efficiently prevent pedestrian fall incidents.

Due to the phenomenon of aging, a new consumer segment known as the "new-silver generation" is emerging. Unlike the previous silver generation, this generation possesses significant economic power and consuming willingness, attracting attention from consumer goods companies. However, both the new-silver generation and the elderly face challenges in adopting contactless or self-service technologies such as self-order kiosks, resulting in negative reactions. Therefore, this study aims to investigate the attitude and response of the newsilver generation towards kiosks, as well as the factors influencing their resistance to such technology. By applying theoretical perspectives from the innovation resistance model, technostress theory, and the value-based model, this study identifies influencing factors for innovation resistance among the new-silver generation when using contactless technologies implemented in fast-food restaurants. The findings indicate that a lower awareness of new technologies and services corresponds to decreased adoption resistance, while a higher perceived value leads to more positive behaviors and attitudes among the new-silver generation utilizing kiosks at fast-food restaurants.

최근 비대면 사회로의 전환으로 많은 조직이 빠르게 스마트워크 환경을 조성하고 있다. 스마트워크의 도입은 단순히 ICT 시스템 또는 솔루션 도입이 아닌 기술적 진보에 맞춰 일하는 방식이나 직무 형태의 다양한 변화를 초래한다. 그러나 스마트워크 관련 기존 연구들은 기술수용관점에서 스마트워크 도입으로 생산성 및 효율성이 향상된다는 연구가 대부분으로 기업의 ICT 시스템이 도입되었을 때 구성원들이 느끼는 혁신저항의 문제와 조직의 관리 통제에 대한 현실적인 문제에 대한 논의는 부족하다. 본 연구는 스마트워크 도입에 대한 혁신요인과 혁신저항에서 구성원들에 대한 조직통제 방법의 조절효과를 실증분석하고 혁신저항의 관점에서 조직의 혁신이 들어왔을 때 구성원들이 저항하는 구조적인 특징을 이직의도로 확장하여 프로세스에 대한 개념적 모델과 가설을 제안하였다. 실증 분석 결과, 스마트워크 도입 관련 ICT 기술의 기업 내부 도입에 대하여 상대적 이점, 자기효능감의 수준이 높을수록 혁신저항의 수준이 낮아지고, 이용복잡성이 높을수록 혁신저항의 수준이 높아지는 것으로 나타났다. 또한 사용자들의 행동통제를 하였을 때 혁신저항이 증가하는 것으로 나타났다. 본 연구의 결과는 사례 분석을 통해 향후 스마트워크 도입에 대한 고려 사항을 제시하여 신규 도입을 위한 경영개선에 기여하는 바를 제공하고자 한다.

Purpose - Although the importance and necessity of "sustainable supply chain management (SCM)" is emphasized, it is often not realized due to conflicting results, the long time required, and large-scale changes brought about by sustainability. This study used the innovation resistance model to confirm the influence of sustainable SCM innovation resistance factors and dynamic capabilities on adoption intentions. This approach made it possible to understand the factors that hinder adoption of sustainability practices and to identify the relationships among influencing factors. It should also help to establish effective policies or strategies. Design/methodology - Through a literature review, the characteristics of sustainable SCM were classified into relative advantage, compatibility, perceived risk, and complexity. The effects of these innovation characteristics on innovation resistance in sustainable SCM and the effects of innovation resistance on adoption intentions were confirmed. In addition, the effects of SCM capabilities on innovation resistance and adoption intentions were analyzed, and the mediating effect of innovation resistance was analyzed. Findings - Compatibility, perceived risk, and flexibility had significant effects on innovation resistance. In turn, innovation resistance had a significant effect on adoption intention, and flexibility had a significant effect on intention to adopt. A partial mediating effect of resistance to innovation was confirmed. Originality/value - Although many previous studies have acknowledged trade-offs with sustainability, most sustainable SCM studies dealt with the correlations among positive drivers of adoption, practices, and performance. This study confirmed the process of accepting sustainable SCM innovation in a single model and is expected to serve as a cornerstone for future sustainable SCM adoption studies. In addition, our findings should help establish effective policies or strategies to activate SSCM adoption by identifying the factors that hinder the adoption of sustainable SCM.

This study first investigated the effects of corn gluten hydrolysate (CGH) (1.5 g/day) administration for 7 days on appetite-responsive genes in lean Sprague-Dawley (SD) rats. In a second set of experiments, the metabolic changes occurring at multiple time points over 8 weeks in response to CGH (35.33% wt/wt) were observed in high-fat (HF, 60% of energy as fat) diet-fed SD rats. In lean rats, the hypothalamus neuropeptide-Y and proopiomelanocortin mRNA levels of the CGH group were significantly changed in response to CGH administration. In the second part of the study, CGH treatment was found to reduce body weight and perirenal and epididymal fat weight. CGH also prevented an increase in food intake at 2 weeks and lowered plasma leptin and insulin levels in comparison with the HF group. This reduction in the plasma and hepatic lipid levels was followed by improved insulin resistance, and the beneficial metabolic effects of CGH were also partly related to increases in plasma adiponectin levels. The Homeostasis Model of Assessment - Insulin Resistance (HOMA-IR), an index of insulin resistance, was markedly improved in the HF-CGH group compared with the HF group at 6 weeks. According to the microarray results, adipose tissue mRNA expression related to G-protein coupled receptor protein signaling pathway and sensory perception was significantly improved after 8 weeks of CGH administration. In conclusion, the present findings suggest that dietary CGH may be effective for improving hyperglycemia, dyslipidemia and insulin resistance in diet-induced obese rats as well as appetite control in lean rats.

Ascochyta blight caused by Ascochyta rabiei (Pass.) Lab. (Telomorph: Didymella rabiei) (Kov.) is one of the most important fungal diseases in chickpea worldwide. Knowledge about pathogen aggressiveness and identification resistance sources to different pathotypes is very useful for proper decisions in breeding programs. In this study, virulence of 32 A. rabiei isolates from different part of Iran were analyzed on seven chickpea differentials and grouped into six races based on 0-9 rating scale and susceptibility/resistant pattern of chickpea differentials. The least and most frequent races were race V and race I, respectively. Race V and VI showed highly virulence on most of differential, while race I showed least aggressiveness. Resistance pattern of 165 chickpea genotypes also were tested against six different A. rabiei races. ANOVA analysis showed high significant difference for isolate, chickpea genotypes and their interactions. Overall $chickpea{\times}isolate$ (race) interactions, 259 resistance responses (disease severity ${\leq}4$) were identified. Resistance spectra of chickpea genotypes showed more resistance rate to race I (49.70%) and race III (35.15%), while there were no resistance genotypes to race VI. Cluster analysis based on disease severity rate, grouped chickpea genotypes into four distinct clusters. Interactions between isolates or races used in this study, showed the lack of a genotype with complete resistance. Our finding for virulence pattern of A. rabiei and newly identified resistance sources could be considerably important for integration of ascochyta blight resistance genes into chickpea breeding programs and proper decision in future for germplasm conservation and diseases management.

해충의 저항성발달로 야기되는 문제를 해결하기 위한 정보를 제공함으로써 향후연구를 촉진시키고자 하였다. 농약사용이 지속되는 한 저항성 발달은 필연적이라는 생각으로, 저항성발달을 지연시키기 위해 재배자가 활용할 수 있는 약제성질에 근거를 둔 약종선택, 혼용, 교호, 모자이크 처리 등 약제살포법과, 천적과 양립할 수 있는 선택성 살충제와 저항성 천적의 이용을 중심으로 한 병해충 종합관리(IPM)에 대해 고찰하였다. 저항성관리에 약종의 성질을 이용할 경우 약종별로 작용점과 mode of action(작용방식)이 같거나 다를 수 있고, 2차 해충과 함께 살충제의 활성, 잔류기간, 약제 저항성 발달에 대한 취약성도 다르다. 약제는 섭식, locomotion(거동), 비행, 교미, 포식자 회피 등에도 영향을 미치므로 종합적으로 고려하여 역교차저항성을 나타내는 살충제의 사용이 바람직하다. 농약혼용은 실제 많이 이루어지고 있고 앞으로도 그러하겠지만, 진정한 의미에서 저항성 발달 지연을 위한 혼용, 교호, 모자이크 처리법은 대립유전자의 우성도, 교차저항성, 유입(immigration), fitness 불이익 등과 함께 살충제의 작용방식과 작용점들의 차이에서 구성약제가 매우 높은 비율로 충을 죽이는 부의 교차저항성을 가진 살충제들의 채택에 대하여 논의하였다. 저항성 관리에 약제혼용의 대표적인 사례 22가지와 교호처리 사례 27가지를 표로 제시하였다. 혼용처리의 잠재적 불이익은 생물적 방제의 와해, 이차해충의 저항성발달, 고도의 저항성 개체군 선발, 다양한 살충제에 대한 교차저항성 범위 확대를 내포하고 있다. 교호처리는 살포약량을 높이거나 낮추고, 다른 대사기구를 가진 살충제를 사용하는 것도 고려되었다. 모자이크 처리는 진딧물 같이 정주성 해충인 경우에 연관없는 살충제를 교호로 다른 구역에 처리하거나, 살충제 처리한 열(列)과 그렇지 않은 것을 혼합 배치하여 저항성 발달을 지연시키거나 피해를 감소시킬 수 있다. 해충의 저항성 진화 측면에서 볼 때, 기생자와 포식자의 저항성과 선택성은 농약처리를 요하는 세대 수를 감소시키고 농약으로부터 피난처의 상보적 역할을 수행할 수 있다. 작물별, 기주별, 기생자와 포식자에게 선택성을 보이는 약제를 별도의 표로 요약하여 제시하였다. 기생자의 생존력 향상을 위해 살충제의 선택성과 선택성에 영향을 주는 내 외적 요인에 대하여 검토하였다. 농약사용 하에서 기생자를 사용하기 위해 농약에 대해 저항성이거나 내성이 있는 기생자를 검정, 채집 혹은 선발하는 것을 논의하였다. 포식자에 대한 선택독성에 영향을 미치는 요인들로 농약의 선택성, 선택성의 포장적용과 그에 미치는 요인, 포식자와 기주의 균형, 선택성을 도외시한 방제법의 문제점, 천적과 농약의 양립성 등에 대하여 논의하였다.
