Background: Lung carcinoma is the leading cause of cancer mortality worldwide. Although the 5-year survival rate nearly tripled from 5-15% over the last 25 years, the estimated number of deaths still exceeds 1.3 million annually. The overall 5-year survival of lung cancer is only 10% in Europe and 15% in the United States. The aim of the current study was to determine the long-term survival and the effect of certain prognostic factors on survival of patients with lung cancer in Yazd city, Iran. Methods: In this cross-sectional descriptive study, we retrospectively reviewed hospital records and follow-up data of 148 patients with histological proven lung cancer using the cancer data registered between 1998 and 2005 in the pathology department of Shahid Sadoughi educational hospital, Yazd, Iran. Data were extracted from patient documents that included sex, age, clinical manifestations, histopathological report of the tumor and type of treatment given. Results: Overall survival time in all patients was 8.5 months after diagnosis and there was no significant difference in survival according to sex (p=0.958). Histological analysis revealed that squamous cell carcinoma was the most common histologic type (35%). Kaplan-Meier statistical methods estimated the average survival time for SCC to be better (22.6 months) in comparison with the other types of histology (all of them below 10 months). There was a trend towards significance between type of histology and duration of survival (p=0.08). Conclusion: It is reasonable to expect that early lung cancer detection, and appropriated treatment, may improve surgical morbidity and mortality. Low survival of lung cancer in our center patients show our shortages in screening programs for early diagnosis. Designing studies with larger sample size that take some other variables like staging of patients is now necessary.
There has been abundant empirical research undertaken on the technical efficiency of Korean ports. Most studies have focused on the use of parametric and non-parametric techniques to analyse overall technical efficiency. This paper utilizes data for the period 2000-07 to offer a heterogeneous perspective on the overall efficiency of Korean ports. The framework assumes that ports use one input to produce one output; the output and input include port export(import) and regional export(import). This paper also employs panel analysis and heteroscedastic Tobit model to show the effect of the explanatory variables on the port efficiencies. The panel analysis shows that the regional export/total export has negative effect on the export efficiency while the regional import/total import has not any relations with the import efficiency. The heteroskedastic Tobit model shows that both regional export ratio and regional import ratio have negative effects on the efficiency while the gross regional domestic product has not any significant relations with the import efficiency.
Effects of native and RS-3 type resistant starches prepared from autoclaved-cooled amylomaize VII(AVII) and normal maize starches(NMS) on the rheological and baking properties of wheat flour dough and quality of breads were investigated. In farinogram, water absorption and dough development time were increased, but stability was reduced by the addition of RS. The addition of native starches or resistant starch made from AVII to wheat flour improved the total volume and specific loaf volume of bread compared with the control(no addition), but the addition of NMS-RS reduced those. During the storage of bread at room temperature, the moisture content of control was decreased but those of native starch- or RS-added breads remained constantly. AVII-RS- or NMS-RS-added bread was evaluated to have good overall acceptability compared with control by elementary school students. The addition of enzyme-resistant starch to bread regardless of botanical sources of starch not only improved the overall acceptability and nutritional benefits but also improved the sensory acceptability.
The milling plants in Korea have been generally used the paddy-separator that operated in accordance with the principle of sieving action. This type of paddy separator was considered as inefficient, especially in relation to the new high-yielding varieties which have different size characteristics within their varieties and also as compared to traditional varieties. With the installation of modern paddy separator it may be possible to increase the overall milling system efficiency and to reduce the grain loss. This study was intended to identify and define important parameters required for assessing the separation performance of a tray-type paddy separator and to determine the optimum conditions of the inclination of separator-table. The results of the study were summarized as follows : (1) Separation performance can be given by use of many parameters found from the measurement of separator outputs. such as upper-tail recovery $(\varepsilon)$, purity of upper-tail $(\gamma)$ , separation recovery of brown rice $(\alpha)$, separation recovery paddy $(\beta)$, and efficiency of separator $(\epsilon)$, Among these para-meters , $\varepsilon$, $\gamma$, $\alpha$ and $\beta$, were designated , respectively, their independent properties of the paddy separator. In addition, their modes of variation due to a varied inclination of the separation table did not indicated in the same direction . However, the efficiency of separator had an advantage to indicate the overall characteristics of the separator performance with a clear optimum inclination condition of the separator table. (2) The optimum feed rate and maximum efficiency of the separator did not occur at the identical inclination of the separator table. Thus, for its practical operation it is necessary to compromise between the qualitative and quantitative performances of the separator. (3) The optimum setting of the separator table tested in the study showed to occur at its inclination of approximately $26^\circ<$/TEX> for the front and $8^\circ<$/TEX> for lateral.
This study analyzed the characteristics of Physical Environment of existing free shuttle bus Interior centered on elderly people who frequently use free shuttle buses. The purpose of this study is to provide basic data that can be used for improvement of existing free shuttle buses. In the case of the old type, in terms of accessible design, the middle entrance is not normally opened except the wheelchair occupant, so that the entrance of the front wheel is always used. Therefore, most elderly people go to the back seat and travel distance is twice longer. In addition, many stairs caused frequent inconveniences for boarding. In the case of the new type, it is planned to be a low-floor type, and various types of safety rods and handles, pictograms for enhancing the information convenience are well-equipped, and the measured value of the overall design characteristic is high. However, in the case of mental stability, it was confirmed that the seat of the bus is colored with a cold color system and is in a different relationship with the warm color which can feel mental stability. Overall, both old and new shuttle buses lack audiovisual feedback on bus routes and route guidance in terms of Supportive design. Also, since the cleaning tools and other miscellaneous items were left in the room, it became an obstacle to space utilization in terms of adaptable design. In terms of safety, both shuttle buses did not come into view with fire extinguishers shaded by miscellaneous items. Therefore, immediate action is unlikely in case of emergency. This problem should be resolved quickly.
An experiment was carried out to evaluate the effects of substituted conjugated linoleic acid (CLA) for fat on qualities, lipid oxidation and residual nitrite contents in emulsion-type sausage (ETS) after different periods of storage. The control sausage contained 20% fat, however, the substituted CLA for fat sausages contained 17.5% fat+2.5% CLA, 15% fat+5% CLA, 12.5% fat+7.5% CLA and 10% fat+10% CLA, respectively. CLA concentration was significantly increased (p<0.05) by substitution of CLA sources for fat, and storage did not affect the CLA concentration. TBARS were significantly increased with the increasing of storage time in all treatments (p<0.05). Significantly higher $L^*$ values were observed in the 10% CLA treatment compared to other treatments during storage. Moreover, $a^*$ values in CLA treatments significantly (p<0.05) increased compared to the control. Again, $b^*$ values were significantly (p<0.05) higher in CLA treatments than those of the control during storage. The concentration of residual nitrite in ETS was significantly (p<0.05) different between the treatments during storage and the results were in the following order: control >2.5% CLA>5% CLA and 7.5% CLA>10% CLA. Overall acceptability of CLA treatments was significantly (p<0.05) lower than the control during storage, whereas no significant differences were found in overall acceptability between the treatments after 28 days of storage.
Purpose: This study relates to the development of dot-sight device, whose length is reduced, with a prism beam splitter. Methods: We developed a new dot-sight device whose length was reduced by eliminating the optical axis tilt of the doublet reflector to reduce the occurrence of the parallax and by redesigning the doublet reflector to use a prism beam splitter. Results: We could develop the new type dot-sight device having a prism beam splitter and the dot reticle generator and the doublet reflector, of which optical axises showed a T-letter type with the optical axis of the observer's eye. Conclusions: In this study, we designed and developed a new type dot sight employing a prism beam splitter that could be able to further enhance the accuracy of the fire in comparison with the traditional dot sight, thereby reducing the overall optical length of system. The new designed dot sight was able to be reduced 2.2 times on the overall optical length, and could be improved more than three times on the accuracy of shooting in the horizontal direction, than the traditional dot sight.
This study examines plant patterns expressed on the fabrics during the Goryeo Dynasty and many countries in the Chinese continent and analyzes their symbolism and formativeness. This study deals with clothes which is one of the most fundamental aspects in a culture and plant patterns on them; it examines the overall formativeness of plant patterns in East Asia from the 10th century to the 14th century by studying plant patterns in the Goryeo Dynasty and the contemporaneous dynasties in the Chinese continent - Five Dynasties, Song Dynasty, Western Xia Dynasty, Liao Dynasty, Jin Dynasty and Yuan Dynasty. The plant patterns of each country were categorized by the type of plant. The composition and expression of plant patterns were examined and statistically analyzed. Small flowers were found in Goryeo fabrics twice more than other types that could be clearly identified, and peony was the most popular flower used in Chinese fabrics. In terms of composition of plant patterns, both Goryeo and Chinese fabrics had plant only patterns more frequently than the patterns mixed with animals or jewels. Regarding expression methods of plant patterns, the most common one in Goryeo fabrics was the petal-type, while the branch-type is the most common one in Chinese fabrics. The plant patterns of the Goryeo Dynasty show beauty of simplicity with minimalism and simplification while expressed with brilliant sold threads on dark background, such as purple or light green, so the overall feeling of fabrics was simple yet nobel.
Low-fat sausages with or without 10% hydrated rice flour were made from duck, chicken and pork and their physical and sensory properties were compared. Results showed that moisture content did not differ significantly among the sausage batters. However, crude protein, crude fat and total ash content were significantly lower in the group with added rice flour compared with the no flour group. Crude protein and crude fat were the highest in pork sausages without rice flour (p<0.05). Adding 10% rice flour reduced total expressible fluid in all meat type sausages. Cooking loss was also decreased when 10% rice flour was used in making sausages from chicken and pork. However, no changes in cooking loss were found in duck meat by adding rice flour. Again, the highest cooking loss was in pork sausages without rice flour and lowest in chicken sausages with 10% rice flour. The pH of the meat from different animal species differs significantly, although no significant difference was found within meat types with or without rice flour. Lightness ($L^*$) increased, while redness ($a^*$) decreased with adding rice flour in all meat type sausages. Results showed that hardness was significantly reduced when 10% rice flour was added to pork, chicken and duck meat (p<0.05). This may be due to increased water retention of rice flour after cooking. Sensory evaluation indicated that the overall acceptability of pork and chicken sausages with or without rice flour was the same, but duck sausages without rice flour had the highest off-flavor score among the sausages. Addition of rice flour increased the overall acceptability of duck sausage to that of pork and chicken sausages.
Static Headspace Gas Chromatographic analysis was used to study the partitioning behavior of five organic printing ink solvents between chocolate cookie/air systems. Three cookie sample formulations varied with respect to chocolate type and overall percentage of constituents. Major considerations involved differences in fat content and type and resulting variability in chemical and physical structure. Each of the solvents studied (ethyl acetate, hexane, isopropanol, methyl ethyl ketone, toluene) represents a general class of printing ink solvents based on predominate functional group. Values of the partitioning coefficient (Kp) were determined at equilibrium using measured quantities of both solvent and cookie sample in closed systems at temperature of 25, 35, and $45^{\circ}C$. In each of the three cookies at the three test temperatures, toluene always exhibited the greatest value of partitioning to cookie and hexane always exhibited the least. Results also showed that the partitioning behavior of solvents is generally inversely related to temperature and that solvent affinity, though constant for a particular cookie type over all test temperatures, varies significantly among the three cookie types. The preference of each of the five solvents for each cookie sample was also found to vary with temperature. No correlation was found between the extent of partitioning and cookie formulation or physical characteristic of solvent. The Hildebrand parameter, related to ${\Delta}Hmix$ (heat of mixing), may be used to describe differences in partitioning based on the overall potential of a solvent/cookie interaction to occur. The potential for interaction is dependent upon the chemical structure of the cookie sample and thus the availability of 'active-sites' required for a given solvent.
