A field-resistant strain of the diamondback-moth(Plutella xylostella L.), collected from Chinese cabbage alpine farmland at Gangwon-do, Korea, was used for determination of the characteristics of resistance to chlorpyrifos using the activities of esterases and glutathione-S-transferase(GST), protein sequestration and AChE insenstivity. Although the activities of esterases extracted from resistant strain and susceptible strain were not significantly different, isozyme bands shown on the electrophoresis were different. GST activity from field resistant strain was 1.5-fold higher than that of susceptible. No differences were shown between resistant and susceptible ones in protein sequestration. The insensitivities of AChE to chlorpyrifos, however, extracted from susceptible strain was 460-fold higher than those of resistant. These results indicated that the insensitivity of AChE is the major factor for developing the resistance and activities of GST might be a minor factor.

본 연구는 노사관계로드맵 쟁점 중 시급히 다루어야 할 사안인 복수노조문제와 전임자 임금지급문제, 실업자 노조가입시 발생할 수 있는 문제에 대해 경제학적 관점에서 고찰하고 시사점을 도출하고자 한다. 복수노조에 관련해서는 1사다노조 사업장 사례에서는 자율적인 창구단일화의 애로사항을 식별할 수 있었으며 노사관계 혼돈기였던 1980년대 중반의 영국경험과 시사점을 통해 창구단일화 실패시 기업성과는 저조하게 되고, 파업발생확률은 상승하는 것으로 나타난다. 따라서 국내외 사례연구는 先자율적 창구단일화 시도 후 실패시 後법적 창구단일화의 필요성을 시사한다. 또한 본 연구는 보조적 기제가 마련된 창구단일화는 반드시 기업별 노사관계에 복종하는 것이며, 산별교섭을 억제하거나 소수노조의 권리를 억압하는 점은 아님을 강조한다. 한편 본 연구는 창구단일화 방식을 검토한 결과, 자율화 실패시 법적강제 창구단일화 방안으로서 과반수대표제가 비례교섭대표제나 배타적 교섭제보다 유리한 점들에 대해 설명한다. 노조전임자 제도변화에 관련하여서는 제도변화가 경제적 효율성 및 공평성에 기여하기 위해서는 전임시간의 투명성과 생산적 투입이 전제되어야만 하고 이를 위해서는 노사협의제도개선과 대기업노조의 집단이기주의 극복이 선행되어야 할 것이다. 마지막으로 실업자의 법적 근로자성 인정은 비정규직 노조결성을 촉진시키고 노조조직률을 상승시켜 근로자의 권리를 강화하는 측면이 있으나 노사관계 및 노노관계의 불안요인으로도 작용할 수 있음을 경제학적 가설들을 통해 설명한다. The purpose of this study is to inquire and deduct conclusions from an economics perspective on issues of the labor-management relationship road map which require urgent attention such as multiple unionism, employer’s wage payment for full-time union officials, and union association of unemployed workers. Regarding the issue of multiple unionism, in the examples of “single management-multiple unions” workplaces, problems in voluntary single table bargaining were identified. The experience of the UK during the mid 1980s in the period of labor-management confusion proves that failure of single table bargaining leads to poor corporate performance and an increased probability of labor strike. Therefore, various case studies from the previous literatures on foreign cases suggest the necessity of legally enforced single table bargaining in the case of failure of prior attempts at voluntary single table bargaining. In addition, this study highlights that single table bargaining with supplementary devices is not necessarily a submission to labor-management relationships of enterprise level, a suppression of industry level collective bargaining, or a suppression of the rights of minority unions. Meanwhile, this study further explains the benefits of majority representation compared to proportional representation or an exclusive bargaining system in the case of enforced single table bargaining due to failure of voluntary efforts. Regarding the issue of adopting a new union official system, for the new change to contribute to economic efficiency and fairness, the transparency of time-off hours and productive inputs must be prerequisite. For these, the labor-management council system must be improved and the collective selfishness of large company unions must first be resolved. Finally, giving legal union right to the unemployed can in some ways strengthen the rights of workers by accelerating the formation of irregular worker unions and by increasing the rate of union organization. However, through the establishment of an economics hypothesis, this study explains that union association of unemployed workers is also an element which may cause insecurity in labor-management relationships and labor-labor relationships.

Diamondback moth(Plutella xylostella L.) recently became a single worst insect which is not controlled effectively by organophosphorus and carbamate insecticides in Kangwon alpine croplands. The objective of this study was to determine if diamondback moth has developed a resistance to organophosphorus and carbamate insecticides. Resistance of diamondback moth, collected at Keichon, Jangpyong, Taebaek, Chunchon, and Hongchon, was determined by the concentration required to kill fifty percent of population, LC??. Their response of resistance varied to insecticides and locations: Taebaek populations were 35 and 70 times more resistant to chlorpyrifos and fenitrothion, respectively, than susceptible(S) population. Hongchon populations were 94 and 254 times more resistant to chlorpyrifos and fenitrothion, respectively, than S population. In addition, Chunchon populations were 37 and 19 times more resistant to profenofos and benfuracarb, respectively, than S population. However, the field populations did not differ in resistance to diazinon, phenthoate, flupyrazofos, carbofuran, and furathiocarb. This study show that field populations of diamondback moth found in Kangwon alpine vegetable croplands have developed a resistance and/or multiple resistance to some insecticides, implying that farmers are losing organophosphorus and carbamate insecticide options for selective control in vegetable crops.

Objectives:Considering the significant limitations of current available interventions on attention-deficit/hyperactivity disorder(ADHD), it has become a consensus among clinicians that new treatment options for ADHD are needed. In recent years, Neurofeedback(NF) has been suggested as a promising possibility. This article aims to review studies that have existing evidence and to inform clinicians on the use of NF as an alternative treatment for ADHD. Methods:Website Pubmed was searched in order to get studies that NF used for treatment of ADHD. We had select studies designed randomized controlled trials, peer reviewed. Results:10 studies and 1 consult study reviewed. There are no positive results except 2 studies reported statistically significant improvement of neurocognitive function. All other studies either did not directly test or did not demonstrate significant differences between θ/β training compared to wait list control, placebo control, or active treatment control. The findings of the studies reviewed do not support NF training as a first-line therapy. Conclusion:ADHD patients have treated with NF in many studies reported results statistically not significant improvement of neurocognitive function. But It’s therapeutic value can not be entirely refuse compared to different empirical treatments. In future, more research is needed on issues such as diversified NF according to ADHD subtypes, patient characteristics, and other non-specific treatment effects.

근로자의 산재보험 장해보상연금과 국민연금 장애연금 간 중복급여 조정 방안

This research aims to propose a policy direction to develop workers` compensation insurance in a sound way, in particular through reexamining and re-balancing the roles played by the insurance and national pension. The research consists of rational management of the insurance, comparison of benefit schemes across countries, and examination of long-term relationship between the insurance and the other social insurance schemes. The country compared is Germany, which are known as having well-established workers compensation system in terms of law, policy, program, and social infra-structure. The comparison, after literature survey, is followed by our policy proposal to reorganize the social insurance systems, focusing on double payment of benefits therein. The proposal is one with a new paradigm of “fairer and wider” hopefully shifted from the existing one with “more, better, and wider” scheme. This research is basically based upon literature survey and case study.

자동차운수업 근로자의 근로시간 개념 및 그 개선에 관한 연구

이상희(Sang Hee Lee),배규식(Kiu Sik Bae),조준모(Jun Mo Cho) 한국노동연구원 2004 노동정책연구 Vol.4 No.2

본 연구는 자동차운수업에서 ILO, EU, 일본의 노동시간 기준을 검토하면서 한국 자동차운수업(택시와 버스)에서 노동시간 측정모형을 세워 이에 따라 택시와 버스기사들의 노동시간을 조사ㆍ분석하였다. 문헌연구를 통해서 일본의 노동시간 측정이 업무의 시작과 끝 시간을 이용함으로써 단순하다는 장점이 있을 뿐 아니라 그에 따른 노동시간 규제가 버스와 택시업의 이질성을 유연하게 반영하고 있음을 알 수 있었다. 또한 유럽연합 규제는 노동시간을 대기시간과 구분하고 있다. 일본과 유럽연합의 노동시간 규제는 한국 자동차운수업 노동시간의 측정과 규제에서 벤치마킹될 수 있는 점들이 있다. 우리는 노동시간의 다양한 구성요소를 뽑아 내어 버스업과 택시업의 맥락에 적합한 노동시간 측정모형을 개발했다. 연구의 경험적 결과는 자동차운수업에서 지나친 장시간노동이 버스업의 복격일제, 택시업의 1인 1차제로부터 비롯됨을 제시하고 있다. 이런 결과들은 자동차운수업을 근로기준법 제58조제1항에서 제외함으로써 장시간노동 문제를 해소하는 노동정책이 필요함을 말해주고 있다. 마지막으로 본 연구는 단체협약에서 시급의 계산을 위한 노동시간의 측정이 공공복지를 위한 노동규제에서 이용되는 위한 노동시간의 측정과 반드시 연계될 필요는 없음을 제시하고 있다. This study examines the ILO, EU and Japanese labor standards of working hours in the road transport sector, and empirically probes on the actual working hours of Korean bus and taxi drivers. The literature survey in this study suggests that the Japanese-style measurements of working hours does not only merit the simplicity by exploiting portal-to-portal hours but the accompanied regulations for working hours flexibly also reflect the heterogeneity of the taxi and bus industry. The EU regulation defines working time separately from the period of availability. The Japanese and EU's regulation may be benchmarked in measurement and regulation of working hours in the Korean road transport sector. We develops working time measurement appropriate to the context of the bus and taxi industry by coming up with a number of factor elements constituent of working time. Our empirical results suggest that the excessively long working hours are attributed to work practice of the third-day off after two consecutive working days in the bus sector and to work practice such as 'one driver (instead of two) responsible for one taxi' in the taxi sector. This empirical results imply that a labor policy are necessary to address the long working hours in the road transport sector by getting rid of the road transport from the Exceptions for Article 58th ① of Korean Labor Standard Law. Finally, this study proposes that the measurements of working hours for the calculation of hourly rate in collective bargaining do not need to be tied with the ones of working hours the regulations for the public welfare.

The objective was to develop herbicides for liquorice (Glycyrrhiza uralensis), one of most important ingredients of herbal medicine in Korea. Soil-applied herbicides, pendimethalin at 1,585 g a.i. ㏊?¹ simazine at 1,000 g a.i. ㏊?¹, alachlor at 5 g a.i. ㏊?¹, metolachlor at 1,600 g a.i. ㏊?¹ and ethalfluralin at 1,050 g a.i. ㏊?¹ provided greater control of hairy crabgrass and barnyardgrass(> 60%) but less control of Abutilon avicennae and Fagopyrum esculentum under growth chamber conditions. Of tested soil-applied herbicides, pendimethalin and simazine showed slight injury to liquorice(<17%). In the field experiment conducted in Chunchon, pendimethalin and simazine provided greater control of weeds: total fresh weight of weeds in control plots was 187 g m?², while those in both herbicides-treated plots were nil. Fresh weights of liquorice seedlings in pendimethalin- and simazine-applied plots, however, were not different from those in control plots. Foliar-applied herbicides, such as dicamba at 964 g a.i. ㏊?¹, 2,4-D at 280 g a.i ㏊?¹, mecoprop at 2,500 g a.i. ㏊?¹, flazasulfuron at 75 g a.i. ㏊?¹, imazaquin at 800 g a.i. ㏊?¹, bentazon at 1,600 g a.i. ㏊?¹, and pyribenzoxim at 30 g a.i. ㏊?¹ reduced the growth of liquorice seedlings and provided moderate to total damage. Overall results show that pendimethalin and simazine appears to be effective herbicide candidates for liquorice.

Two hundred bacterial strains were isolated from the soil around healthy tomato plants in a polyvinyl house, where most of the other plants showed bacterial wilt symptoms. The strains were screened in vitro for their antibacterial activity. Among them, a strain, KPB3 showed strong bactericidal activity against bacterial wilt pathogen, Ralstonia solanacearum. The strain KPB3 was identified using physiological and biochemical tests, and 16S rRNA analyses. Based on these tests, the strain was found to be closer to genus Paenibacillus. To control the bacterial wilt caused by R. solanacearum, greenhouse experiments were conducted to determine the effectiveness of the Paenibacillus strain KPB3. Drench application of this strain (4×10? CFU ㎖?¹) into the pots containing tomato plants, post-inoculated with the pathogen, R. solanacearum could drastically reduce the disease severity, compared to the non-treated plants. To evaluate effectiveness of this strain under field conditions, experiments were carried out in polyvinyl houses infested with R. solanacearum, during spring and autumn of the year 2006. It was observed that, during spring, bacterial wilt was more prevalent compared to the autumn. During spring, 50.9% disease incidences occurred in non-treated controls, while, Paenibacillus strain KPB3 treated plants showed 24.6% disease incidences. Similarly, during autumn, around 17.2% plants were infected with bacterial wilt in non- treated polyvinyl houses, compared to the Paenibacillus strain KPB3 treated plants, which showed 7.0% disease incidences. These results demonstrated that, Paenibacillus strain KPB3 is a potential biological control agent against bacterial wilt caused by R. solanacearum, effective under greenhouse as well as field conditions. This is the first report showing biocontrol of R. solanacearum using a Paenibacillus spp. under field conditions. (Received October 23, 2006; accepted December 23, 2006)
