The Positive List System was newly introduced in South Korea as of January 2007. This study aims to survey and compare perception of and attitudes toward the Positive List System in the process of new drug listing that health professionals and pharmaceutical companies have. 50 professionals and 52 companies answered the questionnaire regarding health policy environments, policy decision/enforcement process, policy effects and satisfaction related to introducing the Positive List System. SAS 9.1 was used for statistical analyses. The results showed that participants had the general sympathy with health policy environments for the introduction of the Positive List System into South Korea. However, the response rates of policy decision/enforcement process and effects were negative and these tendencies were more striking in pharmaceutical companies. As for policy satisfaction, participants marked positive responses more than negative ones. It is necessary to remedy and supplement problems with policy decision/enforcement policy and effects revealed in this study and to improve the Positive List System through gathering opinions among groups and organization concerned.

This study aimed to identify the changes in the list of drugs covered by national health insurance(NHI) after the introduction of positive list system (PLS) in Korea in December, 2006. Six-year (pre-policy:2004-2006, post-policy:2007-2009) lists of the NHI reimbursable drugs filed from Health Insurance Review and Assessment Service (HIRA) were analyzed. The total number of listed drugs as well as drug ingredients, and the average number of listed drugs per manufacturer decreased annually after the introduction of PLS. More than 8,000 drugs were delisted in the year 2007 right after the policy change. Prescription-only drugs occupied more than 85% of NHI listed drugs. The percentage of oral type of listed drugs has been increased to more than 60% after the policy change. Korean pharmaceutical manufacturers occupied more than 90% of listed drugs than multinational firms. The gap between Korean and foreign manufacturer in terms of the average number of newly listed drugs per manufacturer in each year has decreased two years after the PLS (Korean 7.7 vs. foreign 6.3 in 2009) as the price negotiation power of foreign firms has increased. The total number of listed drugs is expected to decrease in the future as the Korean government makes an effort to delist the unnecessary drugs that do not show cost-effectiveness.

To curb a rapid increase in expenditures for pharmaceuticals, the Korean government introduced a positive list system and a negotiation process for drug prices at the end of 2006. Economic evaluation of pharmaceuticals has begun to have a pivotal role in the listing and pricing of drugs for the Korean National Health Insurance. There are some points to discuss regarding the use of economic evaluation in the listing and pricing in the context of the Korean system. First, the listing and pricing processes have been fragmented, evoking complaints from pharmaceutical companies and delaying the access of new drugs to patients. Second, there is a concern that the positive list system may limit the range and availability of drugs for patients to choose for treatment. Third, the time schedule for de-listing of existing drugs may not be realistic. Fourth, it is not always easy to provide reliable evidence of cost-effectiveness due to a lack of materials. Fifth, there is no consensus on the range of the ICER (incremental cost-effectiveness ratio) acceptable to the Korean society. In conclusion, in the near future, it will be necessary to evaluate the achievements that the economic evaluation has provided to the Korean society.

Demand for manpower of conducting pharmaco-economic evaluation was investigated. The priority order of conducting economic evaluation on the already listed drugs was set by the budget impact for health insurance by the therapeutic groups. Manpower demand was estimated by the Anatomical, Therapeutical, Chemical (ATC) code. The total number of economic evaluation on the already listed drugs is estimated to be 346 cases. Based on these numbers, at least 53${\sim}$102 of full-time-equivalent (FTE) manpower is needed for conducting economic evaluation per year in the following 5 years.

미국선녀벌레에 방제효과가 높은 3종 (데리스, 시트로넬라, 계피)의 식물추출물과 보조제 (잔탄검과 실리콘 계열 화합물)를 함유하는 조성물을 개발하였다. 이 조성물은 인삼 재배지에서 미국선녀벌레 방제효과가 90% 이상으로 높았다. 또한 다른 흡즙성 해충에도 살충률이 높아 PLS (positive list system) 전면 시행에 따른 대응방안으로 활용이 가능할 것으로 생각된다.

'농약 허용물질목록 관리제도(Positive List System, PLS)'는 당해 농산물에 등록된 농약 잔류허용기준이 없으면 일률기준 0.01 mg/kg을 적용하는 제도이다. 본 연구에서는 경기도 내에서 유통되는 열대과일류의 잔류농약 모니터링을 실시하여 PLS의 실효성을 검토하고, 국내 재배 열대과일의 농약 잔류허용기준 설정에 기초자료를 제공하고자 하였다. 경기도 내 유통되는 열대과일류 120건에 대해 다종농약다성분 분석법에 따라 잔류농약 220종을 검사한 결과 바나나, 망고, 키위 3품목 7건에서 6종의 잔류농약이 검출되었다. 바나나에서 azoxystrobin와 chlorpyrifos, 망고에서 chlorfenapyr, 키위에서 chlorothalonil, iprodione, procymidone이 검출되었다. 그 중 국내산 망고에서 chlorfenapyr, 국내산 키위에서 chlorothalonil이 각각 1건씩 검출되었고 PLS 적용 결과 잔류허용기준을 초과하여 부적합 판정 되었다. 따라서 국내에서 재배되는 열대과일류를 대상으로 농약 잔류허용기준을 설정할 필요가 있다.

BACKGROUND: The pesticide residue in rotational crop is one of the main concerns to agricultural products because it has the potentiality of violating positive list system (PLS). Thus, the crops used for the rotational cultivation should be considered the pesticide residue patterns to meet the PLS guideline. In this study, we evaluated the residue patterns of fungicide azoxystrobin in radish based on plant back interval (PBI) experiment. METHODS AND RESULTS: Azoxystrobin was treated onto greenhouse soil at 217 g a.i./10a in two different regions. Radishes were sown onto the soil 30 and 60 days after azoxystrobin treatment. The soil and plant samples were subjected to a modified QuEChERS method and LC/MS/MS analyses to determine the residues of azoxystrobin. The methods were validated to meet the guidelines of the pesticide residue analysis recommended by the Rural Development Administration, Republic of Korea. Azoxystrobin was dissipated significantly in soil during the experimental period and found as a level less than 0.01 mg/kg in radish 30 and 60 days after treatment. Azoxystrobin residues in radish samples were lower than the maximum residue limit (MRL) for root vegetables. CONCLUSION(S): This study suggests 30 days as a PBI for rotational cultivation of radish in greenhouse soil that had been treated with azoxystrobin at a level of 217 g a.i./10a.

As a sign of international quality system, ISO9000 certification has been adopted by more and more enterprises. In recent five years, there have been 560,000 certified companies in Europe and America, and there have been more than 390,000 ones in China. It has being attracted many quality scholars' attentions whether ISO9000 certification can bring more benefits to certified companies or not. This paper investigates the ISO9000 certification effect on market performance by the samples from Chinese list companies in shanghai stock exchange. Considering ISO9000 certification as an event, a certification effect model will be set up by means of the event study method, which takes abnormal return rate as a basic indicator to measure the ISO9000 certification effect on Chinese market performance in different event times. Investigation results show that the Chinese certified companies have some positive effects on market performance in the short term. From a long standpoint, the relation between certification and performance has a positive trend.
