Background: The Quality Audit (BQA) program of the Breast Surgeons of Australia and New Zealand (NZ) collects data on early female breast cancer and its treatment. BQA data covered approximately half all early breast cancers diagnosed in NZ during roll-out of the BQA program in 1998-2010. Coverage increased progressively to about 80% by 2008. This is the biggest NZ breast cancer database outside the NZ Cancer Registry and it includes cancer and clinical management data not collected by the Registry. We used these BQA data to compare socio-demographic and cancer characteristics and survivals by ethnicity. Materials and Methods: BQA data for 1998-2010 diagnoses were linked to NZ death records using the National Health Index (NHI) for linking. Live cases were followed up to December $31^{st}$ 2010. Socio-demographic and invasive cancer characteristics and disease-specific survivals were compared by ethnicity. Results: Five-year survivals were 87% for Maori, 84% for Pacific, 91% for other NZ cases and 90% overall. This compared with the 86% survival reported for all female breast cases covered by the NZ Cancer Registry which also included more advanced stages. Patterns of survival by clinical risk factors accorded with patterns expected from the scientific literature. Compared with Other cases, Maori and Pacific women were younger, came from more deprived areas, and had larger cancers with more ductal and fewer lobular histology types. Their cancers were also less likely to have a triple negative phenotype. More of the Pacific women had vascular invasion. Maori women were more likely to reside in areas more remote from regional cancer centres, whereas Pacific women generally lived closer to these centres than Other NZ cases. Conclusions: NZ BQA data indicate previously unreported differences in breast cancer biology by ethnicity. Maori and Pacific women had reduced breast cancer survival compared with Other NZ women, after adjusting for socio-demographic and cancer characteristics. The potential contributions to survival differences of variations in service access, timeliness and quality of care, need to be examined, along with effects of comorbidity and biological factors.

This study assessed the effectiveness of three intervention strategies to improve the participation rate of gastric cancer screening among people who had never undergone such screening, and those who had been screened for the disease, but not recently. It was conducted in the Ilsandong-gu District of Goyang City, Korea. The population for the current study was restricted to male residents, aged 40-65 years, who received an invitation letter to undergo gastric cancer screening from the National Health Insurance (NHI) Corporation at the beginning of 2010. The subjects were divided into two categories according to their screening history: never-screened, and ever-screened. A total of 2,065 men were eligible: 803 never-screened and 1,262 ever-screened. In each screening category they were randomly assigned to one of three intervention groups: 1) tailored telephone counseling; 2) tailored postcard reminder after tailored telephone counseling;and 3) tailored telephone counseling after tailored postcard reminder. At 3 months post-intervention, never-screened men with any intervention were more likely to undergo gastric cancer screening (OR=2.75, 95% CI: 1.22-6.18) compared to those in the reference group (no intervention). However, there was no statistically significant intervention effect in ever-screened men (OR=1.21, 95% CI: 0.65-2.27). Examination of the intervention effects by intervention group among never-screened men showed that those in the postcard reminder after telephone counseling group to be statistically significantly more likely to undergo gastric cancer screening (OR=4.49, 95% CI: 1.79-11.29) than the reference group (no intervention). Our results highlight that use of tailored postcard reminders after tailored telephone counseling is an effective method to increase participation in gastric cancer screening among men who had never been screened.

The health center has to play an important role in promoting community health and satisfying a variety of community health needs and demands in the decentralized Korea. The nearly enacted Community Health Act compels every health center to make its own health plans which intend to deal with local health problems and plan its future health care. This obligation is obviously a big burden to most health centers. They do not have experiences in and abilities of making local health care plans. In order to establish a systematic community health plan, health centers have to concentrate their efforts on enhancing the ability of making health care plan through gathering and analysing the local health informations. However, it is very difficult in reality. This is simply because it will take long time to accomplish these activities. It seems natural that various professionals and researchers participate in carrying out the process of making community health plan in the initial stage. No standardized methodology and analysing framework exist even in the health professional society. Nonetheless, it is common to introduce survey research methodologies in analysing consumer's health care utilization and cost, and in identifying factors influencing health behaviors. Many researchers and professionals have applied social survey methodologies in obtaining information on providers and health policy makers as well. The authors have found that few studies have ever utilized local health data stored at the self-employed medical insurance society as the data source of planning activities. The purpose of this study is to illustrate the usefulness of the data stored at the Sung-Dong Gu Self-employed Medical Insurance Society in establishing the community health plan. The major contents of this study are as follows ; 1. frequency of utilization by age, area, sex, type of medical care institutions, and some major diseases 2. Medical treatment by type of medical care institutions, by classification of 21 diseases, by frequency of three-character categories 3. Medical treatment of major neoplasm and some chronic diseases by age, sex, and area. The conclusion of this study is that it is of great potentiality to find out the local health problems and to use them in blueprinting the community health plan through comparing the frequency of medical utilization analyzed by a variety of variables with NHI health data or the health data from survey research.

본인부담과 관련한 이전의 연구들을 살펴보았을 때 외래와 입원 또는 상병별로 환자개인의 본인부담이 진료비에서 차지하는 비율을 파악하여 우리나라 건강보험이 안고 있는 보장기능의 취약성을 거론하거나 이와는 반대로 의료수요의 가격탄력성을 측정, 소비자의 도덕적 해이의 가능성을 지적하는데 초점을 맞추고 있음을 알 수 있다. 그러나 현재 환자본인이 부담하여야 하는 진료비규모를 파악하여 평균 본인부담액의 실제규모와 본인부담률을 밝히는 동시에 만성질환 보유여부, 의료보장의 종류, 또는 의료서비스 기관에 따른 본인부담의 비형평성 문제에 대하여 직접적으로 논의하는 작업은 극히 미미한 실정이다. 높은 본인부담의 결과로 경제적으로 취약하거나 만성질환에 시달리는 계층이 가장 큰 피해를 입게 된다는 점에서 이에 대한 심도 있는 임상적 및 정책적 논의는 절실하다. 이러한 맥락에서 본 연구는 의료서비스에 대한 계층간 본인부담의 차이가 형평성에 미치는 영향을 분석하고 이에 관련된 정책적 함의를 도출하는데 그 목적이 있다. 본 연구의 결과에서 소득 5분위 대비 최하위 계층의 경우 월등히 높은 만성질환 유병률을 보이고 있음에도 불구하고 최상위층의 6배가 넘는 과중한 본인부담을 안고 있음이 밝혀졌다. 또한 최종적인 회귀분석모형 분석결과는 의료이용 빈도 이외에 환자본인의 인구학적 특성, 가구소득, 만성질환 수, 보험의 종류, 상용치료기관의 종류가 본인부담의 규모를 결정짓는데 있어 영향을 미치는 결정적 요인들로 드러났다.

Purposes: The purpose of this study was to analyze the trends of hospitalization and emergency room visits of asthma patients over the three years in 25 districts of Seoul. And analyzed the relationship between preventable hospital service uses and number of clinics for asthma patients. Methods: Data was collected from a customized database of the NHI(National Health Insurance) for 2016 to 2018. The number of clinics means Internal Medicine, Pediatrics, Ear-Nose-Throat, and Family Medicine clinics. The hospital service means the number of adults admission for asthma and the number of total asthma emergency visits. This study used kappa analysis to assess the agreements of indicators between years, and structural equation modeling analysis was applied to analyze the relationship. Findings: The kappa value of the number of adults admission for asthma was compared between 2016 and 2017(kappa score=0.68), and was lowered when compared between 2016 and 2018(kappa score=0.26). And the value of kappa in the number of total asthma emergency visits due to asthma between 2016 and 2017(kappa score=0.51) was lower than that of between 2016 and 2018(kappa score=0.60). And the results showed that the number of clinics significantly negatively related to the uses of hospital services in asthmatic patients(β=-0.5, p=0.005). Practical Implication: This research could provide policy implications for strengthening primary care services that can contribute to the reduction of preventable hospital services.

세계적으로 노인인구 급증으로 병용약물이 늘어나고, 의료기술의 발달에 따라 다양한 질병 상태의 해소를 위한 약물사용이 늘어나고 있어, 약물의 효과적이고 안전한 사용을 위해 약사의 전문지식에 대한 기대 및 요구는 점차 높아지고 있다. 이에 우리나라는 지난 2009년부터 기존 4년 교육이 아닌 6년제로 약학대학의 학제를 개편하였으며, 고도화된 약료서비스의 제공을 위해 준비된 전문인력을 배출하고 있다. 그러나 현행 국민건강보험 급여체계는 여전히 전통적 약사의 역할인 조제를 중심으로 산정되어, 약사가 제공하거나 제공 가능한 서비스와, 실제로 지급되는 보상급여 간 극심한 간극이 존재하고 있다. 이에 본 연구에서는 약료서비스 지불보상제도의 국제적 동향을 비교분석하여, 현행 한국의 지불보상체계에 시사점을 주고자 하였다. 한국과 일본, 영국 및 미국의 약사서비스 지불보상정책 및 관련 문헌을 검토한 결과, 일본, 영국 및 미국의 시스템은 환자중심의 약료서비스에 대해 제도적으로 구체적이고 다양한 지불수단을 마련하여 보상하고 있으나, 한국의 약국 서비스는 상대적으로 조제관련 행위만 보상하는 정도에 그치고 있어, 국내 약료서비스의 발전을 구조적으로 저해하는 결과를 낳고 있는 것으로 나타났다. 결론적으로, 안전한 약물사용을 위한 환자중심 약료서비스의 제공을 위해서는 국내 지불보상체계가 인정하는 약료서비스의 범위를 확대하고 관련 서비스의 종류를 다양화하여 국내 약사급여제도를 개선시켜나갈 필요가 있다.

Background: Escalating evidence shows that ginseng possesses an antiaging potential with cognitive enhancing activity. As mountain cultivated ginseng (MCG) is cultivated without agricultural chemicals, MCG has emerged as a popular herb medicine. However, little is known about the MCG-mediated pharmacological mechanism on brain aging. Methods: As we demonstrated that glutathione peroxidase (GPx) is important for enhancing memory function in the animal model of aging, we investigated the role of MCG as a GPx inducer using GPx-1 (a major type of GPx) knockout (KO) mice. We assessed whether MCG modulates redox and cholinergic parameters, and memory function in aged GPx-1 knockout KOmice. Results: Redox burden of aged GPx-1 KO mice was more evident than that of aged wild-type (WT) mice. Alteration of Nrf2 DNA binding activity appeared to be more evident than that of NFκB DNA binding activity in aged GPx-1 KO mice. Alteration in choline acetyltransferase (ChAT) activity was more evident than that in acetylcholine esterase activity. MCG significantly attenuated reductions in Nrf2 system and ChAT level. MCG significantly enhanced the co-localization of Nrf2-immunoreactivity and ChAT-immunoreactivity in the same cell population. Nrf2 inhibitor brusatol significantly counteracted MCG-mediated up-regulation in ChAT level and ChAT inhibition (by k252a) significantly reduced ERK phosphorylation by MCG, suggesting that MCG might require signal cascade of Nrf2/ChAT/ERK to enhance cognition. Conclusion: GPx-1 depletion might be a prerequisite for cognitive impairment in aged animals. MCG-mediated cognition enhancement might be associated with the activations of Nrf2, ChAT, and ERK signaling cascade.

유기물 함량이 높은 토양에서는 질소 감비조건에서 관행 시비구와 유사한 수량을 확보할 수 있었던 원인은 토양중의 유기물의 무기화에 의한 암모늄태 질소의 효과적인 방출과 수량구성요소에서 초기에 충분한 분얼수의 확보 그리고 생육후반기에 등숙률의 향상이 그 주요 원인이었다. 결국 수박재배에서 시용한 유기물과 비료성분들이 벼 재배에 일정량 이용될 수 있고 이로 인하여 벼 재배에서는 질소시비량을 줄일 수 있었으며, 추가로 병해충 발생감소와 미질향상의 효과를 규산질비료 시용을 통해서 가능한 것으로 사료되었다. 규산시용에 따른 미질의 향상은 수량이 관행보다 높은 경우에는 유의적인 차이를 보이지 못하였고 비슷한 수량 조건에서는 관행구보다 우수한 미질을 나타내어 적절한 수량과 미질이 우수한 시비체계는 질소 50% 감비에 규산 200% 시용방법이 유리한 것으로 사료된다. 규산 시용에 의한 단위면적당의 광합성활성은 효과가 없었으나, 식물체 전체의 광합성량은 엽면적과 엽신건물중의 증가로 무 규산구보다 높았으며, 순광합성량에 가장 큰 영향을 미치는 형광은 규산 처리구에서 효과적이었다. 결국 규산 시용으로 인한 형광특성의 개선이 벼 식물체 전체 광합성 효율을 높였고 또한 근활력과 건물중의 증가를 고려해 볼 때 수량을 증가 시킬 수 있는 포텐셜을 충분히 내재하고 있는 것으로 사료되었다. 결국 포장조건에서의 규산질비료의 시용은 칼슘과 마그네슘 등의 공조효과가 규산질 단독시용보다는 크며, 규산단독의 효과는 초장과 분얼수, 근활력, 건물중 등에서 낮은 질소시비조건보다는 높은 질소시비조건에서 더욱 유의적인 차이를 나타내는 것은 시비모델식과 일치하였다.
