경기도는 도(道)의 지원으로 성공한 기업의 초과 이윤을 지역으로 환원시킬 수 있는 제도의 틀을 마련하기 위하여 2011년도에 성공기술료 제도를 도입하였다. 향후 성공기술료 징수를 통해 가용 재원 감소기에 지자체의 과학기술 정책 추진을 위한 추가적인 재원을 확보하고, 기술개발사업의 성과를 설명할 수 있는 근거를 확보할 수 있을 것으로 기대한다. 그러나 부담능력이 없는 기업에 추가적인 기술료를 징수함으로써 기업의 혁신에 대한 인센티브를 저하할 가능성에 대한 우려가 있다. 본 연구는 사례분석을 통해서 성공기술료 발생 시의 기업의 부담능력을 분석하는 것으로 목적으로 한다. 분석결과로부터 성공기술료는 실질적으로 부담능력이 있는 기업에만 징수하게 됨으로써 제도의 도입이후에도 기업의 혁신 성공 인센티브를 유지하여 공공기술개발 사업의 정책적 목표를 달성할 수 있는 것으로 나타났다. 그러나 징수의 객관성 확립, 기술사업화의 체계적 지원확대, 고정기술료율 인하로 적정한 기대기술료 수준 유지 등의 제도적 개선이 필요한 것으로 나타났다.

The taxonomic sufficiency approach has been proposed as a surrogate for the typical analysis of species-abundance data, especially in conditions involving prominent pollution gradients. Here, we evaluate the use of taxonomic sufficiency with infralittoral macrobenthic data derived from samples taken in a moderate polluted subtropical environment in southeastern Brazil, analysing five taxonomic levels and including two functional levels throughout polychaete feeding guilds and trophic groups. The data were collected seasonally at nine stations and studied for two abundance data series (0.5 and 1.0 mm sieve mesh-size). The results showed a similar ordination pattern between the two sieve mesh-size, but with the 0.5 mm sieve data a different pattern was observed during austral summer. A slight loss of information was detected using genus, family, polychaete species and their feeding guilds as taxonomic/functional units. These results together with those of the cost! benefit ratio, suggested that the family level seemed to be sufficient to detect the impact caused by moderate pollution in this shallow-water, subtropical environment. In additional, through the use of feeding guilds, similar patterns are obtained. Correlation analysis showed that chlorophyll a, total organic matter, zinc, and chromium sediment content were the variables that best explained the biological pattern observed and not always the best correlation coefficient occurring at the species level. The feeding guild approach seems to be useful and generates interpretable results similar to those obtained with the species level of the whole macroinfauna. The results showed an important cost reduction in the sample processing, suggesting that it is possible to adopt a coarser taxonomic level monitoring program even in species-rich communities.

This study investigates the stigma effect of unwelcomed facilities on apartment prices through multiple regressions based on hedonic price method. The areas studied are Sang-gye Jugong 7, 9, 10 apartment complexes. The facilities analyzed are the Chang-dong Electric Subway Depot and the Do-bong Driver's License Agency. The factors studied include the environmental variable (the elapsed time since the announcement of the re-location of these facilities), the view commanding, the distance from Chang-dong Depot, the distance from Do-bong Driver's License Test Course, the distance from neighboring facilities (subway stations, schools, parks and so on), the floor and each dwelling's exclusive space. The data used are 2,822 sales which have been collected since January 1, 2006. The facts found are as follows; first, the view commanding and the distance from the unwelcomed facilities are statistically significant. second, the environmental variable, 'days' turns out to have a positive (+) and a negative (-) significant relationship with the dependent variable, 'price', in period II and period IV respectively. This implies that the stigma effect is real. third, there are significant differences in the influence on the apartment prices among the independent variables according to time. fourth, the stigma effect is estimated as 33,686,920 Korean won in the case of the apartments which have the view commanding and 30,311,844 won in the other case before the global economic crisis. This effect seems to decrease to 22,085,078 won after the crisis. These facts suggest that stigma effects could be considered as one of the benefits in the cost-benefit analysis of Chang-dong Depot re-location project to produce somewhat higher NPV or B/C ratio.

Recent trial results suggest that the consumption of a low glycemic index (GI) diet is beneficial in the prevention of high blood glucose levels. Identifying active hypoglycemic substances in ordinary foods could be a significant benefit to the management of blood glucose. It has been hypothesized that noodles with Bombyx mori powder are a low GI food. We evaluated GI and changes in postprandial glucose levels following consumption of those noodles and compared them with those following consumption of plain wheat flour noodles (control) and glucose (reference) in healthy subjects. Thirteen males (age: $34.2{\pm}4.5years$, body mass index: $23.2{\pm}1.1kg/m^2$) consumed 75 g carbohydrate portions of glucose and the 2 kinds of noodle after an overnight fast. Capillary blood was measured at time 0 (fasting), 15, 30, 45, 60, 90, 120, and 180 min from the start of each food intake. The GI values were calculated by taking the ratio of the incremental area under the blood glucose response curve (IAUC) for the noodles and glucose. There was a significant difference in postprandial glucose concentrations at 30 and 45 min between the control noodles and the noodles with Bombyx mori powder: the IAUC and GI for the noodles with Bombyx mori powder were significantly lower than those for glucose and plain wheat flour noodles. The wheat flour noodles with Bombyx mori powder could help prevent an increase in postprandial glucose response and possibly provide an alternative to other carbohydrate staple foods for glycemic management.

Background: Although targeted therapy and immuno-oncology have shifted the treatment paradigm for lung cancer, platinum-based combination is still the standard of care for advanced non-small cell lung cancer (NSCLC). Pemetrexed continuation maintenance therapy has been approved and increasingly used for patients with nonsquamous NSCLC. However, the efficacy of this strategy has not been proven in patients without driving mutations. The objective of this study was to compare the clinical benefit of pemetrexed continuation maintenance to conventional platinum-based doublet in epidermal growth factor receptor (EGFR)-negative lung adenocarcinoma. Methods: A total of 114 patients with EGFR-negative lung adenocarcinoma who were treated with platinum doublet were retrospectively enrolled. We compared the survival rates between patients received pemetrexed maintenance after four-cycled pemetrexed/cisplatin and those received at least four-cycled platinum doublet without maintenance chemotherapy as a first-line treatment. Results: Forty-one patients received pemetrexed maintenance and 73 received conventional platinum doublet. Median progression-free survival (PFS), which was defined as the time from the day of response evaluation after four cycles of chemotherapy to disease progression or death, was significantly higher in the pemetrexed maintenance group compared to conventional group (5.8 months vs. 2.2 months, p<0.001). Median overall survival showed an increasing trend in the pemetrexed maintenance group (22.3 months vs. 16.1 months, p=0.098). Multivariate analyses showed that pemetrexed maintenance chemotherapy was associated with better PFS (hazard ratio, 0.73; 95% confidence interval, 0.15-0.87). Conclusion: Compared to conventional platinum-based chemotherapy, premetrexed continuation maintenance treatment is associated with better clinical outcome for the patients with EGFR wild-type lung adenocarcinoma.

본 연구는 2012년부터 2014년까지 국민연금 임의가입자의 계약자 및 계약특성이 해약 행동에 미치는 효과를 로지스틱 회귀모형을 사용하여 분석하였다. 첫째, 남성이 여성보다 탈퇴 오즈가 낮으며 신규가입자 집단에서는 더 큰 차이를 보인다. 둘째, 연령이 증가함에 따라 탈퇴 오즈는 증가하다가 감소하는 특징을 보인다. 셋째, 예상 수익비의 증가는 탈퇴 행동을 억제하는 것으로 나타났다. 넷째, 2013년 국민연금과 기초연금 간 연계 안 발표 결과 전년도에 비해 탈퇴 오즈가 증가하였고 신규가입자 집단에서는 그 크기가 더 크게 나타났다. 다섯째, 17개 광역시 도를 기준으로 광역시 단위에 거주하는, 도시지역 가입자의 탈퇴 오즈가 낮은 것으로 나타났다. 한편, 가입기간과 기준소득 월액과 같은 계약특성의 경우, 탈퇴 오즈에 미치는 영향은 유의미하지만 크기는 작게 나타났다. 본 연구는 향후 임의가입자 유형별 관리방안에 대한 아이디어를 제시하고 특히 예상 수익비의 변화가 해약률에 미치는 영향을 예측할 수 있음을 보였다.

해약율의 추정은 최근 보험제도의 변화 (국제회계기준의 도입에 따른 현금흐름방식의 가격산출체계 시행, 무해약환급금 보험상품의 판매 허용 등)에 따라 보험료의 결정과 손익분석 그리고 리스크 관리 등에 있어서 중요한 요소로 부각되고 있다. 특히, 변액연금은 최저보증옵션으로 인하여 보험계약자의 해약요소가 중요시되고 다른 보험 상품에 비해 복잡하므로 차별성 있는 통계모형의 선택과 분석이 필요하다. 기존의 해약률 연구는 실태분석 또는 회귀분석을 위주로 모형화하는 것에 초점이 맞추어져 있었으나 본 연구에서는 변액연금 계약과 관련된 여러 변수와 최저보증옵션을 반영하기 위하여 생존분석기법 중 하나인 Cox 비례위험모형을 이용하여 해지율을 추정하였다. 변액연금 해지율에 영향을 미치는 주요변수로는 납입방법, 보험료, 보험기간 대비 유지기간, 계약자적립금 대비 최소보증금, 계약자연령이 있으며 본 연구에서는 이에 관하여 분석해보았다.

Cancer is the leading cause of death in the Republic of Korea and cancer death accounts for 27.8% of the total deaths, which is not only a social issue but also a concern for the public. Among the cancer death rates, lung cancer mortality account for 34 deaths per 100,000 populations, making it the number one cancer death rate. In a preliminary report on cancer death in 2012, the lung cancer mortality ratio showed the regional variation indicating that there were differences in the qualitative level and the structure among the medical care benefit agency and in the assessment of the treatment process. Therefore, the Health Insurance Review and Assessment Service (HIRA) had begun evaluation of the assessment of lung cancer treatment since 2014 to improve the quality of lung cancer care through evaluation and feeds back the results of lung cancer care process. In this report, authors described the current Indicators for the lung cancer adequacy assessment proposed by HIRA and results of the evaluation reported in 2017.

Korean agriculture has recently focused on the 6th dimension of industrialization, which includes the functions of healing and care. The green care and healing business is one of the most representative models, satisfying modern consumers' needs for care or healing in rural agricultural environments. Many studies have shown physical and social benefits from green care and healing, but studies regarding economic performance are rarely found. The present study aimed to analyze the economic feasibility of different green care and healing farm complexes proposed in recent domestic research, with various possible combinations of business scenarios. The results show that most of the scenarios are economically feasible as B/C (benefit-cost ratio) and IRR (internal rate of return) are 1.19 and 8.53%, respectively, under scenario 1. This study also performed a break-even analysis for providing more flexible decision-making information. Overall, scenario 1 from green care and healing site and scenario 4 from green care and healing cluster are found to be superior to the other scenarios in terms of B/C and IRR. The scenarios in this study reflect the domestic farms or complexes which have similar functions of care or healing. Therefore, the results of this study provide information on practical policies and business implications in making decisions on the specific size and operational patterns when adopting green care and healing complexes by central or local governments and private sectors in the future.
