Internally Korean insurance market is that whole life products' growth are becoming slowdown that's why new insurance products have appeared on the market in consideration of consumer's needs recently. Externally domestic insurance market competitions has drifted from insurance industry to whole financial industry since bankasurance started. Life insurance companies should open up a new market to survive from severe competitions. Worksite marketing can be an alternative. An insurer make arrangements with an employer about an insurance terms which an insurer offers in Worksite marketing. Then eligible individuals enroll in the plans at their own discretion and pay 100 percent of the premium for coverage through payroll deductions. An employer doesn't need to pay extra money for additional benefit but can raise employee's loyalty and satisfaction of company through worksite marketing. An employee can be covered at discounted premium rate and less strict underwriting guidelines to an insurer compared to individual insurance. In developed countries specially U.S insurance market, Worksite marketing is getting very popular and growing rapidly due to the advantages. Worksite marketing has both individual insurance characters and group insurance characters. Individual insurance characters are that employees enroll in the plans at their own discretion and pay 100 percent of the premium for coverage. Group insurance characters are that actively at work and participation etc. An insurer have to reflect these two characters on Worksite marketing when an insurance company work out a plan for developing products and underwriting guidelines. When an insurer devise worksite products, one should consider participation level which means percentage of eligible employees participating. Participation is related to anti-selection. As we know underwriting is essential for every kind of insurance, especially underwriting plays major role in worksite marketing. We can see that in the below. Firstly, it has a function in calculation of premium rate. When calculate premium rate for worksite products underwriters have to estimate expected participation level and risk factors. So underwriters and acturies keep in close contact with each other. Secondly, underwriting methods are important. When an insurer underwrite worksite products, there are three kinds of underwriting methods. These are Simplified issue underwriting, Full underwriting and Guaranteed issue underwriting. Simplified issue underwriting typically requires no medical examination, but usually requires supplying satisfactory answers to one or several health and/or lifestyle questions. Full underwriting requires a complete medical history questionnaire that may further require an exam. Guaranteed issue underwriting means that coverage is issued without the employee having to provide evidence of insurability. When insurer set the GI limit are usually based on the type of industry, number of eligible employees, the average amount of coverage and participation level. In addition to insurer should have a clear definition of eligible employee on the insurance provision and application form. It will minimize possibility of trouble claims and anti-selection. An insurer also establish preexisting condition exclusion and special guidelines for late entrants. When an insurer introduce Worksite marketing to Korean insurance market, an insurer has to examine market research to analyze potential market and strategy of sales most of all. Also an insurer should review real situation of the U.S, England and Japanese market etc. There are a lot of new technologies about worksite marketing process that an insurer should learn. When an insurer consider many things which we explained it can be a real alternative.

Objectives: The purpose of this study is to investigate the weight loss effects of auricular acupuncture in obese patients. Methods: Six databases (Research Information Sharing Service [RISS], Korean studies Information Service System [KISS], Oriental Medicine Advanced Searching Integrated System [OASIS], PubMed, The Cochrane Library, China National Knowledge Infrastructure [CNKI]) were searched up to May 20, 2020. Eight eligible randomized controlled trials were included the present study. The quality of included studies was assessed by the Cochrane risk of bias tool and a meta-analysis was performed by Review Manager software. A meta-analysis was conducted using a random-effects model and a subgroup analysis was performed to detect the sources of heterogeneity, identify the selection of acupuncture methods and explore its contributions to the weight loss effects. Results: Among 8 trials, 5 trials used auricular acupuncture and 2 trials used auricular acupressure, 1 trial used both types of intervention. Most commonly selected acupoints were Shenmen (TF4) and stomach (CO4). Treatment duration was six to twelve weeks, and total treatment session was six to twelve. Compared to the control groups, auricular acupuncture significantly decreased body weight, body mass index (BMI), high density lipoprotein-cholesterol (HDL) and ghrelin. For the selection of acupuncture methods, both methods performed similarly in most outcome except waist circumference (WC), body fat percentage (BFP), and triglycerides (TG). Conclusions: We found that auricular acupuncture can be effective for weight loss and controlling appetite. However, the findings should be interpreted with caution due to heterogeneity. So further vigorous and well-designed studies should be conducted to strengthen the evidence of the use of auricular acupuncture for obesity.

As disaster risk and climate change volatility increase, there are more efforts to adapt to disasters such as forest fires, floods, and landslides. Most of the research, however, is about influence of human activities on disaster and there is few research on disaster adaptation for species. Previous studies focusing on biodiversity in selecting conservation areas have not addressed threats of disaster in the habitats for species. The natural disasters sometimes play role of drivers of ecological successions in the long run, but they might cause serious problems for the conservation of vulnerable species which are endangered. The purpose of this study is to determine whether soil loss (SL) is effective in selecting habitat management areas for amphibians and reptiles. RUSLE model was used to calculate soil loss (SL) and the distribution of each species (SD) was computed with MaxEnt model to find out the biodiversity index. In order to select the habitat management area, we estimated the different results depending if value of soil loss was applied or not by using MARXAN, a conservation priority selection tool. With using MARXAN, conservation goals can be achieved according to the scenario objectives, and the study has been made to meet the minimum habitat area. Finally, the results are expressed in two; 1) the result of soil loss and biodiversity with MATRIX method and 2) the result of regional difference calculated with MARXAN conservation prioritization considering soil loss. The first result indicates that the area with high soil loss and low species diversity have lower conservation values and thus can be managed as natural disturbances. In the area where soil loss is high and species diversity is also high, it becomes where a disaster mitigation action should be taken for the species. According to the conservation priorities of the second result, higher effectiveness of conservation was obtained with fewer area when it considered SL in addition to SD, compared to when considered only biodiversity. When the SL was not taken into consideration, forest area with high distribution of species were important, but when SL considered, the agricultural area or downstream of the river were represented to be a major part of habitats. If more species data or disaster parameters other than soil loss are added as variables later, it could contribute as a reference material for decision-making to achieve various purposes.

Background: Patients with hematologic cancers have a risk of drug-related problems (DRPs) from medications associated with chemotherapy and supportive care. Although the role of oncology pharmacists has been widely documented in the literature, few studies have reported its impact on cost reduction. This study aimed to describe the activities of oncology pharmacists with respect to hematologic diseases and evaluate the associated cost avoidance. Methods: From January to July 2021, patients admitted to the department of hemato-oncology at Seoul National University, Bundang Hospital were studied. The activities of oncology pharmacists were reported by DRP type following the Pharmaceutical Care Network version 9.1 guidelines, and the acceptance rate was calculated. The avoided cost was estimated based on the cost of the pharmacy intervention, pharmacist manpower, and prescriptions associated with the intervention. Results: Pharmacists intervened in 584 prescriptions from 208 patients during the study period. The most prevalent DRP was "adverse drug event (possibly) occurring" (32.4%), followed by "effect of drug treatment not optimal" (28.6%). "Drug selection" (42.5%) and "dose selection" (30.3%) were the most common causes of DRPs. The acceptance rate of the interventions was 97.1%. The total avoidance cost was KRW 149,468,321; the net profit of the avoidance cost, excluding labor costs, was KRW 121,051,690; and the estimated cost saving was KRW 37,223,748. Conclusion: Oncology pharmacists identified and resolved various types of DRPs from prescriptions for patients with hematologic disease, by reviewing the prescriptions. Their clinical service contributed to enhanced patient safety and the avoidance of associated costs.

Background/Aims: The SAMe-TT₂R₂ score is used for assessing anticoagulation control (AC) quality with warfarin. However, it is hard to apply SAMe-TT₂R₂ score in Asian patients with atrial fibrillation (AF), because it has not been proven in those populations. This study aimed to validate the SAMe-TT₂R₂ score in Asian patients with AF and suggest a modified SAMe-TT₂R₂ score for this population. Methods: We analyzed 710 Korean patients with AF who were using warfarin. The AC quality was assessed as the mean time in therapeutic range (TTR). Each component of SAMe-TT₂R₂ score was evaluated for the relationship with AC. Further clinical factors that predict AC were analyzed. Identified factors were re-assorted and constructed as SA₂Me-TTR scoring system. Results: Of the components of the SAMe-TT₂R₂ score, female, age, and rhythm control were associated with AC. Heart failure and renal insufficiency were newly identified factors associated with AC. The modified SA₂Me-TTR score was reconstructed with the relevant risk factors (S, female gender, 1 point; A, age < 60 yr, 2 points; Me, medical history of heart failure, 1 point; T, treatment for rhythm control, 1 point; T, history of stroke or transient ischemic attack, 1 point; R, renal insufficiency, 1 point). The modified SA₂Me-TTR score demonstrated an excellent relationship with the grading of AC. The modified SA₂Me-TTR score ≤ 1 identified patients with good AC (hazard ratio 2.46, 95% CI 1.75-3.47). Conclusions: The modified SA₂Me-TTR score was useful for guiding oral anticoagulants selection in Asian patients with AF.

토양, 암석, 지하수로부터 실내에 유입되는 라돈은 인간에게 큰 위해를 끼치는 방사능 가스이다. 라돈 가스의 위해성을 확인하기 위해 실내 라돈 농도를 측정해 오고 있는데, 추가적인 분석 수행을 위해서는 신뢰성 높은 분포도 작성이 매우 중요하다. 본 연구에서는 비대칭 분포를 나타내는 라돈 농도의 공간 분포도 작성을 위해 단변량 크리깅 기법들의 비교를 목적으로 정규 크리깅, 비선형 자료 변환 기반의 로그 정규 크리깅, 다중 가우시안 크리깅과 지시자 크리깅의 예측 능력을 비교하였다. 예측 능력을 비교 분석하기 위해 잭나이프 방법을 이용하여 검증을 수행하였으며, 자료 구간별 오차와 샘플링 밀도의 차이에 따른 오차도 추가적으로 분석하였다. 남한 지역을 대상으로 한 사례 연구 결과에서 전반적으로 정규 크리깅에 비해 비선형 자료 변환 기반 크리깅 기법들이 좋은 예측 능력을 보였으며, 비선형 자료 변환 기반 크리깅은 로그 정규 크리깅, 다중 가우시안 크리깅 순으로 좋게 나타났다. 그러나 공간 패턴과 높은 값의 재생산을 고려할 때, 높은 값의 예측 능력은 정규 크리깅이 가장 우수하였다. 본 연구의 결과는 비대칭 분포 자료의 공간 예측을 위한 크리깅 기법의 선정에 유용하게 사용될 것으로 기대된다.
