이 연구는 우리나라 노인장기요양보험의 제도성과를 평가하는데 그 목적이 있다. 정확한 제도성과를 추정하기 위하여 준실험적 방법인 성향점수매칭과 이중차이 결합모형을 이용해 타당성을 저해할 수 있는 요인들을 제거하였다. 노인장기요양보험제도가 사회적 성과변수인 대상노인과 부양가족의 삶의 질과 가족관계 만족도에 미치는 영향을 분석하기 위해 한국복지패널 3-4차 조사자료를 이용하여 성향점수추정을 통해 실험집단과 비교집단을 매칭한 후, 정책시행 이전과 이후 실험집단과 비교집단 간의 성과의 차이를 추정하기 위해 패널고정효과모형을 이용한 이중차이분석을 실시하였다. 그 결과, 노인장기요양보험제도의 대상노인과 부양가족의 삶의 질은 통계적으로 유의미하지 않았고, 가족관계 만족도는 제도시행 이전에 비해 제도시행 이후 향상된 것을 확인할 수 있었다. 이러한 결과는 노인장기요양보험이 실시되고 제도가 충분히 성숙된 시점에 이루어진 평가가 아니라는 한계점을 가지지만, 노인장기요양보험제도의 최종 목표인 대상노인과 부양가족의 삶의 질 향상이라는 정책의 목표실현과 향후 제도개선에 있어서 중요한 함의를 가진다.

This study investigated the effects of L-carnitine (LC) and nicotinic acid (NA) on sperm viability during liquid storage at $18^{\circ}C$ in miniature pigs. $10{\mu}M$ LC and 30 mM NA, combined LC and NA (LN) were treated in fresh semen for 3, 7, and 10 days. In results, sperm survival increased in NA- and LN-treated semen on 7 and 10 days (p<0.05), mitochondrial integrity of live sperm increased in LN-treated semen on 7 days (p<0.05), but not NA-treated semen. In addition, we examined the acrosome reaction of sperm in miniature pigs. LC and NA did not influence on acrosome reaction of boar sperm. In conclusion, LC and NA effectively maintained the viability and quality of sperm during long-term storage in miniature pigs, suggesting that the combined LN may be useful for improving the semen extender for long-term liquid storage in pigs.

Although the sub-chronic toxic effects of metal on fishes are well documented, that is mostly in fishes exposed to waterborne metal but few studied have been conducted on the effects of dietary metal (Handy, 1996). The realization that dietary uptake of metal is a major cause of long-term contamination in wild fish has renewed interest in the nutritional and toxicological effects of metal in the food of fishes (Handy, 1996).

본 연구는 장기 목표 추구 과정에서 의미 부여가 주관적 안녕감에 미치는 영향에서 삶의 의미의 매개 효과를 알아보고자 하였다. 부산 소재 대학생 180명을 대상으로 각자의 장기 목표가 무엇인지 개방형 질문에 대한 답변을 하도록 하고, 목표를 추구하는 과정에서의 의미부여와 삶의 의미 및 주관적 안녕감에 대해 설문조사를 실시하였다. 자료분석은 상관 분석, 위계적 회귀분석을 이용한 매개효과 검증 및 sobel test를 실시하였다. 연구 결과는 다음과 같다. 첫째, 상관 분석 결과 의미 부여, 삶의 의미 및 행복은 서로 정적 상관을 나타냈다. 둘째, 회귀분석 및 Sobel test 결과, 장기 목표 추구 과정의 의미 부여가 행복에 미치는 영향에서 삶의 의미는 완전 매개 효과를 가지는 것으로 나타났다. 이러한 결과는 학생이 장기 목표를 추구하는 과정에서 의미 부여를 하는 것이 전반적인 삶의 의미를 증진시키는 것 뿐 아니라 대학생의 주관적 안녕감을 높이는 데 도움이 됨을 시사한다. 또한 삶의 의미가 대학생의 주관적 안녕감에 매우 중요한 요인임을 보여준다. 마지막으로 후속 연구를 위한 제한점이 논의되었다.

The mechanical and thermal load, and thermal softening occuring by the rush temperature of die, in warm and hot forging, cause wear, heat cracking and plastic deformation, etc. This paper describes the effects of solid lubricants and surface treatments for warm forging die. Because cooling effect and low friction are essential to the long life of dies, optimal surface treatments and lubricants are very important to hot and warm forging process. The main factors affecting die hardness and heat transfer, are surface treatments and lubricants, which are related to heat transfer coefficient, etc. To verify the effects, experiments are performed for heat transfer coefficient in various conditions - different initial billet temperatures and different loads. Carbonitriding and ionitriding are used as surface treatments, and oil-base and water-base graphite lubricants are used. The effects of lubricant and surface treatment for warm and hot forging die life are explained by their thermal characteristics, and the new developed technique in this study for predicting tool life can give more feasible means to improve the tool life in hot forging process.

Mammalian target of rapamycin complex 1 (mTORC1) is a central regulator of cell growth and metabolism and is sufficient to induce specific metabolic processes, including de novo lipid biosynthesis. Elongation of very-long-chain fatty acids 1 (ELOVL1) is a ubiquitously expressed gene and the product of which was thought to be associated with elongation of carbon (C) chain in fatty acids. In the present study, we examined the effects of rapamycin, a specific inhibitor of mTORC1, on ELOVL1 expression and docosahexaenoic acid (DHA, C22:6 n-3) synthesis in bovine mammary epithelial cells (BMECs). We found that rapamycin decreased the relative abundance of ELOVL1 mRNA, ELOVL1 expression and the level of DHA in a time-dependent manner. These data indicate that ELOVL1 expression and DHA synthesis are regulated by mTORC1 in BMECs.

The influence of ginseng on the paste or gelatinization properties by amylograph and mixing properties by farinograph of wheat flour and on quality properties color cooking quality textural and sensory properties and reducing microbial population of LL(Long Life) noodles was studied. The contents of ginseng used were from 5% to 10% based on flour weight. The viscosity property of wheat flour with ginseng was increased the initial pasting temperature but the amylograph peak viscosity were decreased in vice versa. The farinograph absorption stability and breakdown were increased by ginseng. The whiteness of Ll nodles manufactured with ginseng was lower than that of control The shear extrusion force and hardness of LL noodles manufactured with ginseng were shown much higher value than those of control. At cooking quality examination of LL noodles manufactured with ginseng weight of cooked LL noodles was decreased but volum was appeared in ice versa,. Extraction amounts of LL noodles manufactured with ginseng during cooking were much smaller than those of control Total count of microorganism of Ll noodles manufactured with ginseng were decreased during storage at 3$0^{\circ}C$ Sensory properties of cooked LL noodles which was manufactured with ginseng showed quite acceptable. Based on the cooking and sensory evaluation test addition of 7.0% ginseng to wheat flour may be suitable for processing LL noodles.

The purpose of this study was to assess the level of quality of life and related factors among the elderly in Korea. In particular, we focused on factors affecting the quality of life of the elderly in long term care. We used the third Korean National Health and Nutrition Examination Surveys (KNHANES) from 2005. We sampled a total of 3,571 (10.5%) elderly from the national survey. We compared the mean of quality of life to socioeconomic status, Activities of Daily Living (ADL), health behavior, and disease variables. We used EuroQol-5D among KNHANES to assess the quality of life. In this study, the mean score of the quality of life among the elderly was 2.57. Logistic regression showed that the elderly who were male, with spouses, with health insurance, and with good ADL levels enjoyed higher quality of life scores and odds ratios than those who were female, divorced, uninsured, and with low ADL levels (p<.05). The quality of life of the elderly was affected by socioeconomic, ADL, health behavior and disease variables. To improve long term care and the quality of life among the elderly, we need detailed research to clarify the effects of these factors.

Viral diseases cause enormous economic losses to the olive flounder (Paralichthys olivaceus) aquaculture industry in Korea. This study aimed to identify immune-related genes expressed in the kidney of olive flounder injected with Polyinosinic-polycytidylic acid (Poly (I:C)). Thirty fish were divided into two groups by intraperitoneal injection of 100µl of diethylpyrocarbonate-treated water or poly I:C per fish. Kidney tissues at day 3 and 30 after the injection were used for RNA-seq analysis to identify differentially expressed genes (DEGs). Poly I:C group upregulated il8, cfh, tnfaip2b, c3b.2, ly6d and cd38 genes at 3 days post-injection. Additionally, cd22, ccl34a.3, c9, cxcl19, ccl27a, ccl7, and cfh genes were upregulated at 30 days post-injection. Differential expression gene analysis showed that poly I:C has both short and long-term immune effects in olive flounder. This study provides a theoretical basis for understanding the molecular mechanism of the short and long-term immune effects of poly I:C.
