  • 본 연구는 단순 의료이용의 차이를 확인하거나 제한적인 의료필요와 의료이용지표를 활용하여 의료이용의 형평성을 연구한 선행연구의 한계를 극복하기 위하여 수행되었다. 구체적으로 의료필요지표로 활동제한여부, 만성질환이환여부와 수, 주관적 건강상태를 활용하였고 의료이용지표로 외래와 입원, 응급이용횟수와 진료비를 활용하였다. 아울러 의료필요를 고려한 의료이용의 형평성을 분석하기 위하여 집중지수와 집중곡선, Le Grand계수를 활용하였다. 주요 분석결과, 첫째 단순한 의료이용 집중정도로 볼 때 저소득층의 의료이용량이 고소득층에 비해서 많은 것이다. 특히, 저소득층 입원이용이 외래나 응급이용에 비해서 크게 많았다. 둘째, 저소득층에게 의료필요가 집중된 것으로 나타났다. 즉, 저소득층의 건강상태가 좋지 않은 것이다. 셋째, 의료필요를 고려한 의료이용의 형평성을 확인하기 위하여 Le Grand계수를 산출하였다. 의료필요를 고려하더라도 고소득층의 의료이용량이 많았다. 즉, 단순한 양적인 의료이용은 저소득층의 이용이 많았지만, 의료필요를 고려한 의료이용횟수는 고소득층이 많은 것이다. 또한, 전체진료비는 활동제한여부와 만성질환수를 고려했을 때는 고소득층의 의료이용이 많았으며 주관적 건강상태와 만성질환이환여부를 고려하였을 때는 저소득층의 의료이용이 많았다. 따라서 대체로 저소득층이 건강상태에 비해 의료이용을 충분히 하지 못하는 것을 알 수 있었다. 한편, 저소득층의 주관적 건강상태와 만성질환이환여부 관련 의료필요에 비해 의료비지출이 많았는데 이는 저소득층이 스스로의 건강상태와 만성질환이환에 대한 인식을 소극적으로 함으로써 의료필요가 과소평가된 것이 원인으로 사료된다.

  • 산업 발달로 화석 연료 사용이 급증하고 이에 따른 지구 온난화 문제와 자원 고갈 문제가 대두되어 지속 성장을 위협하고 있다. 따라서 지속 성장을 위해서 두 문제를 모두 해결하여야 한다. 현재 이산화탄소의 처리 방법으로 인식되고 있는 이산화탄소 포집 및 저장 기술(carbon capture and sequestration, CCS)의 환경 논란으로 인해 사후 처리 기술의 필요성이 커지고 있다. 이에 해결책중 하나로 부각되고 있는 이산화탄소 포집 및 재활용 기술(carbon capture and utilization, CCU)에 대해서 알아보았다. 이산화탄소 전환 기술은 이산화탄소 배출량 감소에 따른 지구 온난화 문제의 해결 뿐 아니라 탄소원의 재활용이란 측면에서 자원고갈 문제의 해결책으로 제시될 수 있겠다. 이산화탄소 전환 기술은 기상 전환과 액상 전환으로 나눌 수 있으며 기상 전환의 경우 필요 에너지 공급원과 온화한 반응조건에서 전환이 이뤄져야 하고 저에너지 소비 생성물 분리 정제 기술의 개발이 필요하다. 액상 전환의 경우, 반응 속도를 높일 수 있는 촉매 및 광감응제 개발과 함께 촉매, 빛, 전기의 혼성 시스템의 개발이 요구되어진다. 이산화탄소 전환 기술은 신재생 에너지 및 바이오산업의 경쟁력 향상을 위한 연결 기술로 그 가치가 매우 크다.

  • Objective: The study was conducted to evaluate the effect of stocking density and alphalipoic acid (ALA) on the growth performance, feed utilization, carcass traits, antioxidative ability and immune response of broilers. Methods: A total of 1,530 22-day-old male broilers (Arbor Acres) with comparable body weights ($731.92{\pm}5.26$) were placed into 18 cages ($2.46{\times}2.02m$) in groups of 75 birds ($15birds/m^2$, $37.5kg/m^2$; low stocking density [LD]), 90 birds ($18birds/m^2$, $45.0kg/m^2$; high stocking density [HD]) and 90 birds with 300 mg/kg ALA added to the basal diet ($18birds/m^2$, $45.0kg/m^2$; HD+ALA, high stocking density+${\alpha}$-lipoic acid); each treatment was represented by 6 replicates. The experimental period was 3 weeks. Results: The results showed that the high stocking density regimen resulted in a decreased growth, feed conversion ratio, carcass weight, thigh yield and bursa weight relative to body weight (p<0.05) on d 42. The abdominal fat yield in the HD+ALA group was lower (p = 0.031) than that of the LD group at 42 d. The superoxide dismutase and glutathione peroxidase activities in serum were increased, and malondialdehyde content decreased after adding ALA product (p<0.05) on d 42. Additionally, the serum concentrations of immunoglobulin A (IgA) and IgG were decreased (p<0.05) and the level of diamine oxidase was higher (p<0.01) in the HD group on d 42. Conclusion: The high stocking density significantly decreased broiler growth performance, feed utilization and carcass traits, increased physiological and oxidative stress and induced intestinal mucosal injury. The supplementation of ALA product in broiler diet at 300 mg/kg may reduce the adverse effects of high stocking density-mediated stress by maintaining the antioxidant system and humoral immune system.

  • Over-grown seaweeds in Donghae(east sea of Korea peninsula) may impedes ocean environment, however, they can be a good nutrient resources for poultry feeds if they are utilized properly. In this study, seaweeds powder were tested for laying hens\` ration to investigate the effects on egg production rate, egg quality and calcium phosphorus excretion. One hundred 65wks-old brown layers were fed for 5 weeks alotted with seaweeds powder addition to experimental diet by 0(control), 0.5, 1.0 and 2.0%, respectively, and obtained following results; 1. Seaweeds proved a mid-protein low-energy feed resources with planty of K, Na, Ca, Mg, Sr and Fe. 2. Seaweeds addition by 0.5% and 1.0% improved egg production rate and egg-mass output markedly(p<0.05) than control. Seaweeds addition did not alter cholesterol level of yolk and yolk index, however egg shell thickness showed increasing trend by increasing seaweeds addition level. 3. Protein absorption and digestibility in seaweed addition treatments were significantly higher(p<0.05) than control group and protein contents of excreta in 0.5% and 1.0% treatments were reduced(p<0.05), which suggests effective protein metabolism for egg production. Increasing seaweeds addition reduces Ca and P contents in rectum and excreta, suggesting Ca and P utilization improvement in laying hens and lessening soil pollution. 4. In conclusion, seaweeds addition in layers' diet by 1.0% level improves egg-mass production and might be egg quality by increasing metabolism of protein, calcium and phosphorus.

  • This study was conducted to evaluate dietary hydrolyzed pig bristle meal (PBM) for juvenile olive flounder Paralichthys olivaceus. In Experiment 1 (EXP-1), six experimental diets were prepared to contain 0, 3, 6, 9, 12 and 15% PBM (designated Con, PBM3, PBM6, PBM9, PBM12 and PBM15, respectively). Triplicate groups of olive flounder (initial body weight, 8.69 g) were fed the diets to apparent satiation for 8 weeks during the optimal water temperature season ($20.5{\pm}2.12^{\circ}C$). All PBM supplemented groups except for PBM3 showed significantly lower growth performance and feed utilization compared to the control group. The protein digestibility of PBM3, PBM6, and PBM9 diets did not significantly differ from that of the control diet. In Experiment 2, 1% mono-calcium phosphate was added into the experimental diets used in Exp-1. Triplicate groups of olive flounder (10.6 g) were fed the diets to apparent satiation for 8 weeks during the low water temperature season ($12.5{\pm}1.12^{\circ}C$). The growth performances and feed utilization of fish fed all diets except for PBM15 diet did not significantly differ from those of the control diet. This study indicates that hydrolyzed PBM can replace fish meal by up to 12% with limiting amino acids and mono-calcium phosphate in diets for juvenile olive flounder.

  • The Korean native black pig (KNP) have several desirable meat qualities, which are highly demanded by Koreans in spite of its slow growth rate, low feed efficiency, and small litter size. The aim of this study was to evaluate meat quality and fatty acid composition of KNP at different slaughter weight in order to provide information to industry. Ninety female KNP of the same age (220 days) were divided into three groups by live body weights (30 pigs per each group); live weight of 50$\sim$59 kg (T1), 60$\sim$69 kg (T2) and 70$\sim$80 kg (T3), respectively. After slaughtering the longissimus dorsi muscle (LD) and backfat from each group were obtained after 24 hr chilling. Crude protein content and shear force of LD from T3 was higher than that from T1 and pH of LD was significantly lower in that from T1 than from T2 and T3. Color measurement indicated that LD of T2 group had a higher $L^*$-value and lower $a^*$-value than those of T1 and T3. Slaughter weight of KNP generally did not affect the fatty acid composition of LD and backfat but the content of oleic acid (C18:1) of T2 in LD was significantly higher than those of T1 and T3. The results may provide basic information to industry to promote the production and processing of KNP, and assist in meeting the Korean consumer's demand.

  • The dietary fiber alginic acid has no nutritional value; however, it decreases the utilization of nutrients by the body and can prevent obesity, hyperlipidemia, arteriosclerosis, constipation, and colon cancer. The low-molecular-weight alginic acid polymannuronate improves serum and liver lipid metabolism by decreasing cholesterol levels in high-cholesterol groups and may be used to control high blood pressure. Previously, we showed that polymannuronate, a physiologically active agent from seaweed, has a lipid-lowering effect and preventative role in colon cancer. In addition, the differentiation of polymannuronate-treated adipocytes was inhibited, triggering decreased leptin expression. This study examined ways to increase dietary satisfaction with and improve the nutritional quality of polymannuronate using hamburger buns supplemented with polymannuronate. Twenty male Sprague-Dawley rats were divided into two groups: the control group was fed hamburger buns containing 6% gluten, while the experimental group was fed hamburger buns containing 6% gluten and 10% polymannuronate. The serum triglyceride, phospholipid, and total and free cholesterol levels of the rats in the experimental group were decreased compared with those of the controls. The serum aspartate aminotransferase activity levels did not differ between the two groups. This study demonstrates that polymannuronate has beneficial effects on lipid metabolism and may be commercially useful.

  • An index that evaluates the health level of a population group considering both death and loss of function due to disease is called a summary measure of population health (SMPH). SMPHs are broadly divided into life year indices and life expectancy indices, the latter of which comprise healthy life expectancy (HLE). HLE is included as a policy target in various national and regional level healthcare plans, and the term "HLE" is commonly used in academia and by the public. However, the overall level of understanding of HLE-such as the precise definition of HLE and methods of calculating HLE-still seems to be low. As discussed in this study, the types of HLE are classified into disability-free life expectancy, disease-free life expectancy, quality-adjusted life expectancy, self-rated HLE, and disability-adjusted life expectancy. Their characteristics are examined to facilitate a correct understanding and appropriate utilization of HLE. In addition, the Sullivan method, as a representative method for calculating HLE, is presented in detail, and major issues in the process of calculating HLE, such as selection of the population group and age group, estimation of death probability, calculation of life years, and incorporation of health weights, are reviewed. This study will help researchers to select an appropriate HLE type and evaluate the validity of HLE research results, and it is expected to contribute to the vitalization of HLE research.

  • 최근, 해변모래의 침식을 방지하기 위해 잠제를 설치하고 있다. 잠제설치는 모래 침식의 손실을 최소화하기 위해 만들어졌다. 이런 이유로, 잠제를 무분별하게 전국적으로 계획하여 건설하고 있다. 그러나 해안선 유지를 위해 설치된 잠제는 상당히 문제가 있는 방법이다. 고가의 건설비, 해양공간이용, 해수수질, 해안선 변화 등의 단점도 있다. 특히, 해양 레저를 즐기는 이용자들은 해상공간이 단절되기 때문에 이를 좋아하지 않는다. 광안리와 같은 해수욕장은 인위적으로 양빈모래를 공급하여 해수욕장을 유지하는 곳이다. 연성공법이란 양빈모래의 유실방지를 위해 수중에 잠재를 대신하여 유동성 재질로 폭 넓은 연성구조물을 설치하는 공법을 말한다. 본 연구는 해변 침식을 완화할 수 있는 연성공법의 일환으로 cell group을 설치하였다. 즉, 양빈모래의 유실을 막기 위해 잠제 대신에 cell group을 사용하여 사빈침식의 정도를 완화 할 수 있는 공법을 적용한 것이다. 2차원 고정상 실험에서 cell group의 설치로 인한 파고감소효과 및 저반사율을 제시하였고, 이동상 수리모형실험에서, cell group 설치로 인한 양빈모래의 포착률과 양빈 모래의 침식방지율을 제안하였다. 따라서 수리모형실험의 결과에 의하면 침식해안의 사빈에 cell group을 설치하면 파고감소효과, 저반사율과, 양빈사의 침식방지율, 양빈사의 높은 포착률에 의해 양빈사의 유출이 방지되어 안정된 해안을 유지할 수 있었다.
