This study was carried out to investigate the effects of olive oil on the quality characteristics of pressed ham. Five different treatments were tested based on differences in the amount of olive oil added to the pressed ham. As a control, 10% back fat was added without any olive oil. For the first treatment, 5% olive oil replaced a portion of the lard component added to the press ham. For the 2nd, 3rd and 4th treatments, 10%, 15% and 20% of olive oil were substituted for lard, respectively. Pressed ham manufactured with olive oil was vacuum packaged and stored for 1, 7, 14, 21 and 28 days at $4^{\circ}C$. Samples were analyzed for shear force value, sensory properties, TBARS values and fatty acid composition. Shear force values increased significantly during storage for all treatments. No remarkable differences were found in sensory properties (color, flavor, texture, and acceptability) between the control and olive oil treated hams, and there was no clear change with increased storage time. There was no significant difference in TBARS values between the control and olive oil treated hams. The TBARS values increased significantly during storage for all treatments. With regard to changes in fatty acid composition, the contents of C14:0-C20:4 were decreased significantly by the addition of olive oil. The saturated fatty acid and polyunsaturated fatty acid contents of the control were significantly higher than the olive oil treated hams. Higher levels of added olive oil resulted in significantly higher monounsaturated fatty acid contents. Based on these findings, we conclude that the sensory properties and lipid oxidation (TBARS) of manufactured pressed hams are not affected by olive oil addition. These results also indicate that high-quality pressed ham can be manufactured with increased monounsaturated fatty acid content.

아리스토텔레스의 교육이념 : 인간론을 중심으로

이정일 명지대학교 인문과학연구소 2008 인문과학연구논총 Vol.29 No.-

인간은 자선에게 주어진 가능성 전체를 실현할 때 비로소 자기 충족적인 행복을 누릴 수 있다. 교육은 자신에게 속한 고유한 가능성을 현실적으로 이루어내는 데 있다. 개벌 인간이 자신으로서 자신의 전체가 되는 것이 교육의 목적이다. 인간은 자연인으로 태어나지만 교육을 통해 자기를 비로소 완전하게 만들 수 있다. 합목적적이고 자기 충족적인 삶을 살기 위해서 인간은 자신을 도야시키지 않으면 안 된다. 교육에서 덕이 필요한 것은 인간 각자가 자신에게 주어진 고유한 궁극 가능성을 완성하는 한에서만 요구된다. 덕은 탁월함을 말하는 데 교육에 있어서 탁월함은 바로 성격의 일관성을 통해 자신의 과제를 완성하기 때문에 그렇다. 인간 본성 안에 뿌리 깊이 박혀 있는 행복추구의 정당성은 덕과 교육의 매개된 통일을 통해서만 가능하다. Aristoteles calls someone eudaimon only if that person comes fairly close to the ideal life for all human beings. whereas our standard of happiness is measured by the fulfilled life. We must think of happiness as no more than a subjective psychological state. The way is largely clear for transforming the prima facie case which we started into a reasonably settled conviction. Eudamonia has after all a deep kinship with the accomplished life, in so far as it can be viewed as the ultimate end of our action and pedagogy. One should seek to immortalize oneself( = the realization of his possibility) but only within the bounds of the life of practical wisdom and moral virtue.

Synthesis of Scheelite Structural Yb3+, Er3+ Co-doped NaLa(MoO4)2 and Its Green Upconversion Luminescence

이정일,류정호 한국물리학회 2014 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.65 No.10

The polycrystalline Er3+/Yb3+ co-doped NaLa(MoO4)2 phosphor was synthesized, and its greenupconversion (UC) luminescence properties were investigated in detail. Under 980-nm excitation,Er3+/Yb3+ co-doped NaLa(MoO4)2 exhibited weak red emissions near 660 nm and 670 nm andstrong green UC emissions at 530 nm and 550 nm corresponding to the intra 4f transitions ofEr3+ (4F9/2, 2H11/2, 4S3/2) ! Er3+ (4I15/2). The optimum doping concentrations of Er3+ andYb3+ for the highest emission intensity were determined by using X-ray diffraction (XRD) andphotoluminescence (PL) analyses. The Er3+/Yb3+ (7.0/10.0 mol%) co-doped NaLa(MoO4)2 phosphorsample exhibited a strong, shiny, green emission. A possible UC mechanism for Er3+/Yb3+co-doped NaLa(MoO4)2 depends on the pump power is discussed in detail.

The effects of gamma radiation((60)^Co) was studied on the shelf-life of chicken breasts. The chicken breasts were aerobically packed by polyethlene films and exposed to a gamma ray source at ambient temperatures. The dose levels applied were 0, 0.5, 1.0 and 2.0kGy. The irradiated samples were stored together with the nonirradiated at 4±1℃. When the dose of gamma radiation was increased, the biological level showed decreased, leading to the increment of shelf-life. Especially, 1.0 and 2.0kGy of gamma irradiated samples resulted in 10^(3)CFU/㎠ after 10 days of storage and when the shelf-life increased with the irradiation dosage, the samples showed a significant decrease in lactic acid bacteria and psychotrophs(P$lt; 0.01). Thiobarbituric Acid Reactive Substance (TEARS) values, did not increase in this study. The Volatile Basic Nitrogen (VBN) values were decreased with the level of irradiation. Lightness(L value) tended to decrease as the irradiation dosage increased. However, redness and yellowness tended to increase with the irradiation dosage. The result of descriptive analysis with scaling for raw and cooked chicken breast showed that off flavor intensity decreased as the irradiation increased in the raw meat but increased in the cooked one. The degrees of acceptability in the raw and cooked chicken breast decreased as the irradiation does increased. The result of triangle test revealed that the degrees of difference were siginificant between 0.5kGy irradiated raw chicken breast and the others (P$lt; 0.05). In the cooked chicken breast, the degrees of difference were not significant between the 1.0kGy and 2.0kGy irradiated treatments.

To investigate the effects of conjugated linoleic acid (CLA)-added diet feeding on CLA accumulation and fatty acid composition of chicken, a total of 150 Bramas broiler was fed both CLA-free and CLA-added (1, 2.5 and 5%) diet for 2-8 weeks of age weeks. The CLA used to add in diet was chemically synthesized by alkaline isomerization method with safflower oil. The pH, peroxide value (POV), thiobarbituric acid reactive substances (TBARS), cholesterol content, fatty acids composition and CLA concentration in breast and leg of chicken were measured. Samples from CLA-treated group showed higher pH and lower POV value than control group, and the both values were significantly affected by CLA levels in diet and/or feeding periods. Also the cholesterol content of meat was decreased with increasing CLA level in diet and/or feeding period. CLA was not detected in control chicken. However, the CLA concentration in meat from CLA-added diet was increased with increasing of CLA level in diet and feeding period. The highest CLA concentration in chicken breast was detected after feeding 5% CLA-added diet for 5 weeks. The fatty acid composition was changed with increasing CLA concentration in the meat that the proportion of palmitic acid was increased whereas that of linoleic acid and arachidonic acid were decreased. It was suggested that CLA could be accumulated in chicken meat by dietary CLA supplementation, and the CLA concentration and fatty acid composition in the meat could be affected by CLA level in diet and feeding period.

This study was carried out to investigate the effects of grape seed oil on quality characteristics of pressed ham. Five different treatments were tested based on differences in the amount of grape seed oil added to the pressed ham. As a control, 10% back fat was added without any grape seed oil. For the first treatment, 10% grape seed oil replaced a portion of the lard component added to the pressed ham. For the 2nd, 3rd and 4th treatments, 20%, 30% and 40% of grape seed oil were substituted for lard, respectively. Pressed ham manufactured with grape seed oil was vacuum packaged and stored for 1, 7, 14,21 and 28 d at $4^{\circ}C$. Samples were analyzed for chemical composition, physico-chemical properties (pH, color) and texture characteristics. Typical chemical composition characteristics (crude protein, crude fat, crude ash) were not significantly different between control and grape seed oil treatment groups. Moisture content of grape seed oil treatment groups (GSO 30% and 40%) was significantly lower than that of controls (p<0.05). There was a not clear difference in pH between control and grape seed oil treatment groups. In the 21 d of storage, pH values of all treatments were significantly higher than those of other storage days. Meat color $(CIEL^*\;and\;b^*)$ of grape seed oil treatment group (GSO 40%) was significantly higher than that of control. Whereas meat color a value of GSO 40% treatment was significantly lower than that of control. It was not clearly changed as storage time increased. There was no significant difference in texture between control and grape seed oil treatment groups, and appeared to be unaffected by storage length. Based on these findings, we conclude that the chemical composition and texture characteristics of manufactured pressed ham were not affected by grape seed oil addition. These results also indicate that high-quality pressed ham can be manufactured with increased polyunsaturated fatty acid content.

In order to identify the risk factors for shunt dependency and to select the optimal treatment modality of hydrocephalus in medulloblastoma patients, fifty two patients with medulloblastoma, who were treated at Seoul National University Hospital from 1982 to 1% were reviewed. Retrospectively the authors analyzed the types of treatment and the results in the fifty patients of hydrocephalus associated with medulloblastoma. Two cases of perioperative death were excluded from the statistical analysis. The initial management of hydrocephalus in 50 patients included 1) ventriculoperitoneal shunt(WS) before the removal of tumor in 6.2) external ventricular drainage(EM)> before the removal of tumor in 4, 3) intraoperative ventricular puncture and placement of EVD or internalized reservoir(IVD, internalized ventricular drainage) for continuous or intermittent cerebrospinal fluid(CSF) drainage postoperatively in 29.4) no procedures of CSF drainage before or during the operation for tumor removal in 11. Among the 44 patients in whom preoperative VPS was not inserted. 16 finally required permanent VPS after tumor removal and 28 remained shunt-free. Factors which might predict the need for permanent VPS were analyzed and tested statistically. The presence of symptoms and signs of increased intracranial pressure, the severity of hydrocephalus on computerized tomography (CT), T and M stage, and the type of initial management of hydrocephalus were not statistically significant factors influencing the shunt dependency. The only two statistially sigmfkant features predicting the need for a subsequent permanent shunt were : 1) incomplete tumor removal(p=0.025) and 2) postoperative hematoma in the fourth ventricle(p=0.004). Among the 11 patients without preoperative or intraoperative EVD, 4 required shunt placement after tumor removal. of which 3 needed urgent placement of EVD. Preoperative or intraoperative EVD could have played a role as a safety mechanism in those patients. On the other hand. the preoperative or intraoperative EVD did not enhance the rate of infection or shunt dependency. In the cases of ventricular installations for CSF drainage, simple externalization of ventricular catheter and postoperative continuous CSF drainage(EVD) seemed to be associated with a lower rate of infection compared with the method of postoperative intermittent puncture and drainage through the internalized reservoir(IVD), but the difference of infection rates between the two groups were statistically insignificant(p=0.557). The average duration of CSF drainage in the externalized EVD group was shorter than that of internalized reservoir group(5.4 versus 10.7 days). In conclusion 1) the preoperative or intraoperative EVD is useful as a safety mechanism while it dose not enhance the possibilities of shunt dependency and infection, 2) for the patients in whom the placement of subsequent permanent shunt is highly expected the EVD with the internalized reservoir can be a good choice. An algorithm for the management of hydrocephalus was suggested.
