  • This survey was done to construct a nursing theory according to Korean culture and to identify the Korean traditional view. From ancient time until now, shamanism has played an important role as determinant of Korean culture and of the personality formation of Korean people. The subjects are 321 patients and member of their families who were over 18 years old, and who are living in five large cities and two rural communities in Korea. Data collection was done from March, 8th to April, 29th in 1999. SPSS The tool developed by the investigator through literature review was used to measure the perception and the attitude of patients and their families to Korean shamanism. Collected data were analyzed by frequency, percent and $x^2$ test with SPSS program. The results are summarized as follows ; 1) While 35% of respondents answed that the destiny or fate(八字) was only relied on the abilities and endeavor of individual, 65% of respondents were fatalists(運命論者) or eclectic(折衷主義者) are compromised between the fate and endeavor. 2) While half of the respondents belief in divination(占) to some degree, the rest of them reported hardly any belief in divination. 3) There were almost twice as many respondents who directly consulted fortune-tellers were as respondents who did not consult fortunetellers. 4) The reasons for consulting fortunetellers were job problems, home problems, health problems by in that order. 5) The respondents almost always interpreted the cause of physical disease and mental disease as being psycho-sociological, but 1% of them explained mental disease as a shamanistic manitestation. 6) In case of disease, the reasons for consulting a fortuneteller was a) no hope of recovery from the sickness in any other way, b) the chronic disease in that order. 7) Of the respondents, 65% answered that diseases could not be cured by a 'Gut' (the performance done by the shaman), but 27% of respondents thought that disease could be cured by a 'Gut' in the case of mental disease. 8) Sixty six percent of the respondents answered that they have experienced praying for their wishes with clean water(井華水). 9) While 54% of the respondents answered that they have seen or heard the 'Beung Gut'(the performance to pray for recovery of sickness done by the shaman), 46% responded that they have never seen or heard it. 10) To the question 'do you intend to have a 'Beung Gut', 51.7% of respondents answer 'no' strongly, but 48% of them say 'yes' or took a compromising attitude. 11) Generally the respondents differed in perception and attitude to shamanism. In short, females more than males, old aged more than younger aged, lower educated more than higher educated, believers in Buddhism more than believers in any other religion, and blue color more than white color have more positive attitudes to shamanism. Also men living in rural communities have more positive attitude to shamanism than men living in the large cities. Consequently, Shamanism can be understood as an anxiety relieving cultural system even though Shamanism itself looks like a cultural complex.

  • Purpose of this research is estimating polymerization depth of different source of light. XL 3000 for halo-gen light, Apollo 95E for plasma arc light and Easy cure for LED light source were used in this study. Different shade (B1 & A3) resin composites (Esthet-X, Dentsply, U.S.A.) were used to measure depth of cure. 1, 2, and 3 mm thick samples were light cured for three seconds, six seconds or 10 seconds with Apollo 95E and they were light cured with XL-3000 and Easy cure for 10 seconds, 20 seconds, or 40 seconds. Vicker's hardness test carried out after store samples for 24 hours in distilled water. Results were as following. 1. Curing time increases from al1 source of lights, oui$.$ing depth increased(p<0.05). 2. Depth (that except 1mm group and 2mm group which lighten to halogen source of light) deepens in all groups, Vickers hardness decreased(p<0.05). 3. Vicker's hardness of A3 shade composite was lower in all depths more than B1 shade composites in group that do polymerization for 10 seconds and 20 seconds using halogen source of light(p<0.05), but group that do polymerization lot 40 seconds did not show difference(p>0.05). 4. Groups that do polymerization using Plasma arc and LED source of light did not show Vicker's hardness difference according to color at surface and 1mm depth(p>0.05), but showed difference according to color at 2mm and 3mm depth(p<0.05). The results showed that Apollo 95E need more polymerization times than manufacturer's recommendation (3 seconds), and Easy cure need polymerization time of XL-3000 at least.

  • The purpose of this study was to investigate the effect of marination condition(immersion and tumbling) on quality characteristics of cured pork meat and sensory properties of pork jerky. Pork meat was immersed for 1, 6, 12, 24, and 48 hours or tumbled for 10, 20, 30, and 60 minutes with curing solution. The jerky was made from cured pork meat, immersed for 6, 12, 24, and 48 hours or tumbled for 10, 20, 30, and 60 minutes. The curing yields and water holding capacity in immersion and tumbling treatments were increased as marination time increased, and the curing yields of tumbling treatments were higher than those of immersion treatments, but water holding capacity was not. The pH value of all treatments were not significantly different. CIE L*- and b*-value of immersion treatments were significantly decreased as marination time increased, but CIE a*-value were increased. Objective color of tumbling treatments showed a similar tendency with those of immersion treatment. The sensory properties of pork jerky were not significantly different between immersion and tumbling treatments.

  • Purple rice is a strain of glutaneous rice rich in anthocyanins and ${\gamma}$-oryzanol. Both types of compounds are involved in antioxidant and lipid metabolism of mammals. Three experimental diet types were used which consisted approximately by half either of purple rice, white rice or corn. Diets were fed to $3{\times}10$ pigs growing from about 30 to 100 kg. Meat samples were investigated either as raw or cured loin chops or as smoked bacon produced from the belly. Various physicochemical traits were assessed and data were evaluated by analysis of variance. Traits describing water-holding capacity (drip, thaw, and cooking losses) and tenderness (sensory grading, shear force) of the meat were mostly not significantly affected by the diet type. However, purple rice feeding of pigs resulted in lower fat and cholesterol contents of loin and smoked bacon compared to white rice, but not compared to corn feeding except of the fat content of the loin. The shelf life of the raw loin chops was improved by purple rice as well. In detail, the occurrence of thiobarbituric acid reactive substances after 9 days of chilled storage was three to four times higher in the white rice and corn diets than with purple rice. The n-6:n-3 ratio in the raw loin chops was 9:1 with purple rice and clearly higher with 12:1 with the other diets, meat lipids. Level and kind of effect of purple rice found in raw meat was not always recovered in the cured loin chops and the smoked bacon. Still the impression of flavor and color, as well as overall acceptability were best in the smoked bacon from the purple-rice fed pigs, whereas this effect did not occur in the cured loin chops. These findings suggest that purple rice has a certain, useful, bioactivity in pigs concerning meat quality, but some of these effects are of low practical relevance. Further studies have to show ways how transiency and low recovery in meat products of some of the effects can be counteracted.

  • The composite resin, due to its esthetic qualities, is considered the material of choice for restoration of anterior teeth. With respect to shade control, the direct-placement resin composites offer some distinct advantages over indirect restorative procedures. Visible-light-cured (VLC) composites allow dentists to match existing tooth shades or to create new shades and to evaluate them immediately at the time of restoration placement. Optimal intraoral color control can be achieved if optical changes occurring during application are minimized. An ideal VLC composite, then, would be one which is optically stable throughout the polymerization process. The shade guides of the resin composites are generally made of plastic, rather than the actual composite material, and do not accurately depict the true shade, translucency, or opacity of the resin composite after polymerization. So the numerous problems associated with these shade guides lead to varied and sometimes unpredictable results. The aim of this study was to assess the color changes of current resin composite restorative materials which occur as a result of the polymerization process and to compare the color differences between the shade guides provided with the products and the actual resin composites before- and after-polymerization. The results obtained from this investigation should provide the clinician with information which may aid in improved color match of esthetic restoration. Five light activated, resin-based materials (${\AE}$litefil, Amelogen Universal, Spectrum TPH VeridonFil-Photo, and Z100) and shade guides were used in this study. Three specimens of each material and shade combination were made. Each material was condensed inside a 1.5mm thick metal mold with 10mm diameter and pressed between glass plates. Each material was measured immediately before polymerization, and polymerized with Curing Light XL 3000 (3M Dental products, USA) visible light-activation unit for 60 seconds at each side. The specimens were then polished sequentially on wet sandpaper. Shade guides were ground with polishing stones and rubber points (Shofu) to a thickness of approximately 1.5mm. Color characteristics were performed with a spectrophotometer (CM-3500d, Minolta Co., LTD). A computer-controlled spectrophotometer was used to determine CIELAB coordinates ($L^*$, $a^*$ and $b^*$) of each specimen and shade guide. The CIELAB measurements made it possible to evaluate the amount of the color difference values (${\Delta}E{^*}ab$) of resin composites before the polymerization process and shade guides using the post-polishing color of the composite as a control, CIE standard D65 was used as the light source. The results were as follows. 1. Each of the resin composites evaluated showed significant color changes during light-curing process. All the resin composites evaluated except all the tested shades of 2100 showed unacceptable level of color changes (${\Delta}E{^*}ab$ greater than 3.3) between pre-polymerization and post-polishing state. 2. Color differences between most of the resin composites tested and their corresponding shade guides were acceptable but those between C2 shade of ${\AE}$litefil and IE shade of Amelogen Universal and their respective shade guides exceeded what is acceptable. 3. Comparison of the mean ${\Delta}E{^*}ab$ values of materials revealed that Z100 showed the least overall color change between pre-polymerization and post-polishing state followed by ${\AE}$litefil, VeridonFil-Photo, Spectrum TPH, and Amelogen Universal in the order of increasing change and Amelogen Universal. Spectrum TPH, 2100, VeridonFil-Photo and ${\AE}$litefil for the color differences between actual resin and shade guide. 4. In the clinical environment, the shade guide is the better choice than the shade of the actual resin before polymerization when matching colors. But, it is recommended that custom shade guides be made from resin material itself for better color matching.

  • This study was conducted in order to assess whether the form of the shade guide affects in deciding the color of the teeth using the shade guide Eight shade light cured composite resins (Esthet-X, Dentsply, Milford, USA) were used in this study. Shade guides including the model of maxillary central incisors, teeth-form shade guide, doughnut form shade guide, and shade guide with perforated gray shield were prepared with eight shade composite resins and provided the codes randomly After arranging the models of teeth, 19 dentists working at the clinic of the Dentistry of Chonnam University Hospital and 65 students of college of dentistry, Chonnnam University selected the shade guides corresponding to the color of each tooth on the gray board under the D$_{65}$ standard illuminant. Bl shade showed highest accuracy of about 95% among all shade guides of 3 forms applied to the test and regardless of observer, tooth form shade guide showed the highest accuracy (p < 0.05) , and the doughnut form showed the lowest accuracy (p < 0.05). At the time of deciding on the color of the teeth using the shade guides as a result of above, the forms of the shade guides can affect the accuracy, and it suggests that the development of the diversified forms of shade guides, which may obtain more accurate results, is required.

  • Varying amount of ginseng was added to pork and chicken breast meat at various pH for a model system. Pork and chicken breast meat sausages were manufactured with 2.5% of ginseng and varying concentration of nitrite. Ginseng reduced the lipid oxidation in the pork except at pH 4.5 whereas promoted in the chicken breast meat regardless of pH. In the presence of ginseng, nitrite decreased the lipid oxidation of the sausages with increasing concentration. Cured color formation increased with an increase of ginseng upto 7.5% in the pork whereas upto 2.5% in the chicken breast meat. Redness of the pork sausage containing ginseng increased with an increase of nitrite. Lightness of the chicken breast meat sausage containing ginseng decreased with increasing nitrite level.

  • Objectives: This study evaluated the effects of the resin thickness on the microhardness and optical properties of bulk-fill resin composites. Materials and Methods: Four bulk-fill (Venus Bulk Fill, Heraeus Kulzer; SDR, Dentsply Caulk; Tetric N-Ceram Bulk Fill, Ivoclar vivadent; SonicFill, Kerr) and two regular resin composites (Charisma flow, Heraeus Kulzer; Tetric N-Ceram, Ivoclar vivadent) were used. Sixty acrylic cylindrical molds were prepared for each thickness (2, 3 and 4 mm). The molds were divided into six groups for resin composites. The microhardness was measured on the top and bottom surfaces, and the colors were measured using Commission Internationale d'Eclairage (CIE) $L^*a^*b^*$ system. Color differences according to the thickness and translucency parameters and the correlations between the microhardness and translucency parameter were analyzed. The microhardness and color differences were analyzed by ANOVA and Scheffe's post hoc test, and a student t-test, respectively. The level of significance was set to ${\alpha}=0.05$. Results: The microhardness decreased with increasing resin thickness. The bulk-fill resin composites showed a bottom/top hardness ratio of almost 80% or more in 4 mm thick specimens. The highest translucency parameter was observed in Venus Bulk Fill. All resin composites used in this study except for Venus Bulk Fill showed linear correlations between the microhardness and translucency parameter according to the thickness. Conclusions: Within the limitations of this study, the bulk-fill resin composites used in this study can be placed and cured properly in the 4 mm bulk.
