  • The purpose of this study was to comprehend the selection process of quarry and the quarry Jogyedong through the Salleung-uigwes in royal tombs constructions in the late Joseon period. Especially, it is to comprehend about the effect by difference of use of stone between Daebuseokso and Sobuseokso. Following conclusions have been reached through the study. First, the quarry of Daebuseokso had been selected very carefully through the quality check process. Second, the quarry of royal tombs around the capital was located at Mt. Bulam in the east and Mt. Bukhan in the west. This is because the nature of the procurement of stone, which is important for transportation, is that it is necessary to prepare the mountains close to the royal tombs. Third, the locations of quarry of between Daebuseokso and Sobuseokso were differently selected. The quarry of Daebuseokso was located at a distance of three times distant from Sobuseokso. Forth, the epigraph related to quarry is located in Sareung construction in the valley of Jogyedong. This is a very important data to confirm the location of royal tombs construction.

  • To examine factors affecting feeding efficiency of grey herons (Ardea cinerea), the foraging behavior was studied at a reservoir in Asan city, Chungcheongnam-do, South Korea during the breeding seasons (from April to July) of 2006 and 2007. Four factors (age of foraging birds, time of day, breeding stage, and microhabitat type) were analyzed. Adults were more efficient foragers than recently fledged juveniles, and they had a higher success rate than juveniles. About half of the adults caught large prey, whereas most juveniles caught only small prey. Adult grey herons had different feeding efficiency according to the breeding stage. Pecking and capture rates were high during the late period (fledging stage), and biomass intake rates were high during the early (incubating stage) and late periods. However, time of day had no significant effect on foraging activity of adult grey herons. Feeding activities of adult grey herons also showed significant variation among microhabitat types. Pecking and capture rates were higher in the submerged plants area, but capture success rate and biomass intake rate were not different according to microhabitat type.

  • Solvothermal treatment of late transition metal acetylacetonates in a novel medium composed either of pure acetophenone or acetophenone mixtures with amino alcohols offers a general approach to uniform hydrophilic metal nanoparticles with high crystallinity and low degree of aggregation. Both pure metal and mixed-metal particles can be accesses by this approach. The produced materials have been characterized by SEM-EDS, TEM, FTIR in the solid state and by Nanoparticle Tracking Analysis in solutions. The chemical mechanisms of the reactions producing nanoparticles has been followed by NMR. Carrying out the process in pure acetophenone produces palladium metal, copper metal with minor impurity of $Cu_2O$, and NiO. The synthesis starting from the mixtures of Pd and Ni acetylacetonates with up to 20 mol% of Pd, renders in minor yield the palladium-based metal alloy along with nickel oxide as the major phase. Even the synthesis starting from a mixed solution of $Cu(acac)_2$ and $Ni(acac)_2$ produces oxides as major products. The situation is improved when aminoalcohols such as 2-aminoethanol or 2-dimethylamino propanol are added to the synthesis medium. The particles in this case contain metallic elements and pairs of individual metals (not metal alloys) when produced from mixed precursor solutions in this case.

  • The objective of this study was to examine the effect of compensatory growth nutritional regimen on mammary gland growth and lactation. One hundred twenty-two Sprague Dawley female rats (35 days of age) were randomly assigned to either a control or a stair-step compensatory nutrition (SSCN) feeding regimen or an alternating 2-2-3-3-week schedule beginning with 40% energy restriction for 2 weeks followed by re-alimentation (control diet) for 2 weeks. Pup weight gain and milk yield were improved 8% and 8 to 15%, respectively, by the SSCN regimen. The gene expression of $\beta$-casein was 2.3-fold greater in the SSCN group than in the control group during early lactation, but they were greater at all stages of the second lactation. The gene expression of insulin-like growth factor-I was 40% lower in the SSCN group than in the control group during early lactation of the second lactation, but during late lactation it was 80% greater than in the control group. The concentration of serum corticosterone tended to be higher in the SSCN group during the late stage of the first lactation. These results suggest that the stair-step compensatory nutrition regimen improves lactation performance and persistency by modulation of cell differentiation and apoptotic cell death.

  • It has been since 15 century when Ainu realized themselves as a race. Their folk culture had been formed with the effect of East-northern Asia and cultural exchange with Japanese through the northern trade during 17 -18 centuries. It can be ascertained from the typical festival food and clothing. clothing style and the ornaments of Ainu people. The basics of Ainu people are composed of an unfolding clothes which men and women had wort in one-piece style even though they had lived in the northernmost cold climate. Atousi is their typical clothing which had been made of the grass fiber. Ainu people had imported the old cotton clothes from the trading with the mainland roughly in the late E-do (late 18 century). Ainu's clothing is divided broadly into Aiusi and Moreu pattern. Ainu people had decorated their back, shoulder, collar, burial clothes, waist and hem by changing and mixing them. These are the expression of their desire to prevent themselves from the wicked plot or the devil. There is no similar Ainu patterns or skill in Kimono, while it is known to be rather related to the area of Amur River, Sakhalin, and the distant Mongolia. Therefore, the traditional pattern of Ainu should be the continental conception which had been skilfully shaped through the trading with the north adding the series of Ainu People.

  • It is considered that jacket was widespread in the 19th century due to its simple and convenient production technique. This study aims to explore the western women's jacket in the late 19th century, which is the basis of modern women's outwear, and we focused on the patterns and construction, the technical aspect of the jacket. We researched pattern books and preserved costume materials, and the study methods are as follows: First, we analyzed the pattern of the jackets from the pattern books and preserved costumes. Second, we analyzed the construction of the jackets from the preserved costumes and compared it to previous researches. The study results are as follows: 19th century jacket consisted of a bodice, a back bodice, a side panel, two-piece sleeve and a collar. The front bodice had cuttings and a dart to make the jacket fit the shape of the body and the two-pieced leg of mutton sleeve, puffed at the shoulder. Various styles of collar and neckline existed. The pattern suggested diverse ways of designing a jacket, such as cutting with partition, dart and pattern expansion that focused on three-dimensional effect at that time.

  • A retrospective cohort study was carried out with 340 female breast cancer at a teaching university in northeast of Thailand recruited and followed-up until the end of 2006. Survival probabilities were estimated using the Kaplan-Meier method. 161 cases were alive after five years and 58 patients were lost to follow-up. The overall observed survival rates at 1, 3 and 5 years were 83.3%, 59.9% and 42.9%, respectively. When analysis was conducted for stage combined into 2 groups, early (stage I, II and unknown) and late (stage III and IV), the 5-year survival rate for early stage (60%; 95%CI: 0.51-0.67), was higher than for late stage (27%; 95%CI: 0.19-0.34) with high statistical significance (p<0.001). The hazard ratio of patients with stage IV was 11.6 times greater than for stage I (p=0.03). The findings indicate that the different stages of breast cancer markedly effect the overall survival rate.

  • The Purpose of the current study is to identify the differences between Samsung and Hyundai Group and the causes why the differences occurred. The study focuses on the founders of the two group as a main source of the differences, especially brain preference of the two founders. Two steps were employed to perform the study. Firstly, the two founders' characteristics were analyzed by using archival research. It was implicitly hypothesized that Group founders' characteristics explained the differences of the two Groups. It was found that the founder of Samsung Group, the late president Lee emphasized rationality, analysis, and cause/effect relationship and low risk taking, suggesting that he had left-brain preference. In contrast. the late president Chung, the founder of Hyundai Group, emphasized intuition, wholeness, contextual meaning, and risk taking, showing that he had right-brain preference. Secondly, a comparison between the two groups was performed in terms of business and financial risk in corporate portfolio, and management system. It was found that Hyundai Group was pursuing higher risk than Samsung Group. And it was observed that Samsung Group put more emphasis on formality in decision making and systematic control, and less emphasis on risk taking than Hyundai Group. From the two step research relationship between brian preference and management was reasoned. Research implications and limitations were discussed at the end of the study.

  • Several growth characteristics of two ornamental tobacco species, Nicotiana sanderae and N. affinis, were investigated in this study. Also effect of temperature and daylength on the flowering of the tobacco plants were evaluated to obtain basic information on breeding and cultivation. 1. The plants were great in high temperature-long day at the early stage and in low temperature-short day at the late stage of plant growth, for both Nicotana species. At the early growth stage the leaf length N. sanderae was great in high temperature-long day, and that of N. affinis was great in high temperature-short day period, while at the late stage of the plant growth the leaf lengths were more significantly effected by the temperature rather than daylength. Leaf width and leaf shape index were less sensitive to the conditions. 2. For both of the species, the total number of tobacco leaves not much influenced by the temperature and daylength. 3. There were no significant differences for budding and flowering period between the two species, both of which were sensitive to temperature and daylength with more influence by daylength than temperature. 4. Number of floral stalks, number of flower and flowering period were not much influenced by temperature and daylength; however, N. affinis had 2 more floral stalks, 31 more flowers, and 6 day longer flowering period than N. sanderae.
