Three experiments were conducted to determine the effects of non-ionic surfactant (NIS) supplementation on ruminal fermentation, nutrient digestibility and performance of beef steers fed high-roughage diets. The objective of experiment 1 was to investigate the effects of NIS supplementation on in vitro ruminal fermentation of cultures administered with corn and barley as grain substrate and rice straw and timothy hay as roughage substrate. The in vivo ruminal fermentation, nitrogen balance and digestibility of nutrients were also examined with steers fed a high-roughage diet in experiment 2. The aim of experiment 3 was to determine the responses to NIS of growing steers fed a high-roughage diet. In experiment 1, ammonia nitrogen concentration for NIS supplementation was higher (p<0.05) than for the control with all substrates. However, concentrations of total volatile fatty acid (VFA), acetate, butyrate and valerate of the incubated roughage substrates, rice straw and timothy hay, were higher (p<0.05) for NIS supplementation than for the control whereas VFA concentrations in the cultures of corn and barley were unaffected. These results indicated that effects of NIS on ruminal fermentation are diet dependent, specifically on roughage sources. In experiment 2, ruminal pH of steers supplemented with NIS was lower (p<0.05) than the control. Ruminal concentrations of ammonia nitrogen, acetate, total VFA and urinary concentrations of purine derivatives were increased (p<0.05) by NIS supplementation. In experiment 3, supplementation of NIS increased (p<0.05) intakes of total feed and corn silage, average daily gain, and feed efficiency of growing steers although they varied depending on supplementation level. Due to the roughage-specific feature of NIS effects, NIS appears to enhance ruminal fermentation of fibrous parts of feeds and, consequently, performance of steers fed a high-roughage diet.

Asthma is a prevalent and serious health problem in Korea. Recently, the Korean Asthma Guideline has been updated by The Korean Academy of Tuberculosis and Respiratory Diseases (KATRD) in an effort to improve the clinical management of asthma. This guideline focuses on adult patients with asthma and aims to deliver up to date scientific evidence and recommendations to general physicians for the management of asthma. For this purpose, this guideline was updated following systematic review and meta-analysis of recent studies and adapting some points of international guidelines (Global Initiative for Asthma [GINA] report 2014, National Asthma Education and Prevention Program [NAEPP] 2007, British Thoracic Society [BTS/SIGN] asthma guideline 2012, and Canadian asthma guideline 2012). Updated issues include recommendations derived using the population, intervention, comparison, and outcomes (PICO) model, which produced 20 clinical questions on the management of asthma. It also covers a new definition of asthma, the importance of confirming various airflow limitations with spirometry, the epidemiology and the diagnostic flow of asthma in Korea, the importance and evidence for inhaled corticosteroids (ICS) and ICS/formoterol as a single maintenance and acute therapy in the stepwise management of asthma, assessment of severity of asthma and management of exacerbation, and an action plan to cope with exacerbation. This guideline includes clinical assessments, and treatment of asthma-chronic obstructive pulmonary disease overlap syndrome, management of asthma in specific conditions including severe asthma, elderly asthma, cough variant asthma, exercise-induced bronchial contraction, etc. The revised Korean Asthma Guideline is expected to be a useful resource in the management of asthma.

Rubella is a viral disease with mild constitutional symptoms and generalized rashes. In childhood, it is an inconsequential illness, but when it occurs during early pregnant period, there are significant risks of heart defects, cataract, mental retardation to the fetus. The series of congenital defects induced by rubella is called 'congenital rubella syndrome'. Many research have been performed to find out more effective prevention program on rubella. The objectives of this study are, first, to calculate the incidence rate of acute rubella infection and congenital rubella syndrome in Korea, second, to evaluate economic efficiency of several rubella vaccination policies and to offer data for the most reasonable decision on vaccination policy. Study populations are 663,312 children of one year-old in 1992. The author has performed cost-benefit analyses according to the three vaccination policies-U.S.A.'s. U.K.'s and Sweden's. In this Study, the author got the incidence rate of acute rubella infection using the catalytic model. In the meantime, the author used 50 per 100,000 live births as the incidence rate of congenital rubella syndrome. The discount rate used in this study was 5 percent per annum. The sensitivity analyses were done with different discount rates (4%, 7%) and different incidence rate of congenital rubella syndrome (10,100 per 100,000 live births) : The study results are as follows: 1. Without vaccination, lifetime expenditures per patient for acute rubella infeciton amount to 14,822 won and the total expenditures to about 3.1 billion won. Meanwhile, lifetime expenditures per patient for congenital rubella syndrome amount to about 91 million won and the total expenditures to about 16.3 billion won without vaccination. 2. The cost of vaccination for a child of one year old was 2,322 won and the total cost for the one year old children was about 1.5 billion won (American style). The cost for vaccination of female children at fifteen was about 339 million won (Birtish style). And the cost of vaccination at one for both sex and female children at fifteen was about 1.9 billion won (Swedish style). 3. The benefit to cost ratios of vaccination of female children at fifteen that is the british mode of rubella vaccination, was 60.0 at the level of 80% population coverage and 48.6 at 100% coverage. It shows much higher benefit to cost ratio than those of the other two vaccination policies. 4. Both net benefits of vaccination at one (American style) and that of vaccinations at one and fifteen (Swedish style) range from about 17.0 billion to 17.8 billion won, those were larger than that of vaccinations of female children at fifteen (Birtish style, about 16.0 billion). 5. In marginal cost-benefit analysis of only additional program of revaccination, the benefit to cost ratios were 3.6 (80% coverage rate) or 0.6 (100% coverage rate). It implies that additional program was less efficient or inefficient. 6. In sensitivity analysis with different discount rates(4% or 7%) and different incidence rates of congenital rubella syndrome (10 or 100 per 100,000 live births), the benefit to cost ratios has fluctuated in wide range. However, all the ratios of vaccination of female children at fifteen were higher than those of the others. Even under the most conservative assumption, the benefit to cost ratios of all the rubella vaccination policies were higher than 3.3. In conclusion, all the rubella vaccination policies found to be cost-effective and particularly the vaccination of female children at fifteen was strongly recommended.

본고는 베버리지 보고서 원문에 담긴 의료보장 및 복지 구상을 검토하고, 베버리지의 기획이 오늘날 영국 NHS를 통해 어떠한 방식으로 현실에서 구현되었는지를 규명하고자 노력한다. 20세기 복지 사회의 근간을 형성한 베버리지 보고서의 영향력을 염두에 둔다면, 보건의료 영역에 관한 베버리지 보고서의 본래적인 기획은 무엇이었으며, 그것이 국가 의료 시스템인 NHS로 얼마나 충실히 계승되어 구현되었는지를 알아보는 과제는 흥미롭지 않을 수 없다. 또한, 보건복지 정책이 현대 국가에서 차지하는 비중을 고려한다면, 베버리지가 제시한 의료보장 기획 및 그 내용이 오늘날까지 이어져 왔는지를 살피는 노력은 시의적절하다. 위의 문제의식을 바탕으로, 본고는 베버리지 보고서에 담긴 의료보장 구상과 NHS를 통한 구현을 다음과 같이 알아본다. 우선 베버리지 보고서의 역사적인 배경을 다루어 베버리지가 제시한 복지체계의 기원을 살피며, 복지 제도의 개혁을 주동한 시대정신의 역할 및 영국 전시생산체제와 응급의료서비스의 경험을 주요 논점으로 부각한다. 그 후 당대의 사회현실로부터 태동한 베버리지 보고서의 의료보장 구상이 무엇인지를 분석하는 단계가 진행되며, 이때 사회복지를 향한 목표와 의료보장에 관한 계획이 주목된다. 마지막으로, NHS의 지향과 운용 방식, 치료 유형, 재활 프로그램을 포함한 현황을 차례로 검토하고 베버리지 보고서와 비교분석하여 저자의 기획이 현실에서 충실하게 구현되었는지를 살핀다. 이 과정에서 본고는 베버리지 보고서 원문은 물론이며, 잉글랜드 NHS 헌법과 1946년 국민보건서비스법을 비롯한 주요 법정책 자료를 참고하여 연구 목적을 달성하고자 노력한다. 본고의 탐구는 단지 베버리지 보고서의 답습에 그치지 아니하고, 현대의 관점에서 복지국가에 대한 베버리지의 기여를 평가하여 되돌아본다는 지점에서 그 의의가 있다. 베버리지 보고서에 담긴 지향과 정책 등을 구조화하여 분석하고, 이를 NHS의 현실에 접목하여 비교분석하는 본고의 서술은 베버리지의 기획이 영국에서 착실하게 구현되었는지를 살피는 적절한 기회를 마련할 수 있다. 더 나아가 본고는 보건의료 분야 복지의 과거와 현재를 비판적인 시각에서 반추하려는 노력의 일환이며, 한국 의료보장 및 복지 관련 법 제도의 미래와 개선을 염두에 두는 건설적인 탐구에 적절한 시사점을 남길 수 있으리라고 기대한다.
