The Gwugonsiuebang is a book of Korean woman's life in the Yi dynasty which published I 1653 by Mme. Jang. I have studied the food habits of the Yi dynasty that wrote in Gwugonsiueband as following. The staple foods are Guksu (wheat vemicell as like western noodles) 5, Mandu (bun stuffed with seasoned meat and vegetables) 6 kinds in this book. the side dishes are Guk (soup) 8, J'm (steamed meat or fish) 6, chae6, Nooruemi 5, Hyae (sliced raw fish) 3, Jockpyun (jellied beef soup) 3, Jockgall (salted sea food) 2, Jock (skewer or broach) 2, jihee 2, Sun (Steaming of stuffed vegetable) 1, Bockuem (saute) 1, Jon (pan fried fish) 1, Gui (meat or fish grilled with seasoning) 1, and the other 13 kinds. The desserts are D,ock (Korean rice cake) 11, jabgwa 8, Beverages 5 kinds and Jungwa 1 kind. The alcohol and fruits wine are 51 kinds. The alcohol and fruits wine are 51 kinds. The seasonings are Soybean sauce, oil, Sesamol oil, pepper, Ginger, Garlic, Vinegar, Wine, Salt, Bean paste etc. Raw materials of Guksu, Mandu, D'ock, Jabgwa, Beverage, Wine, vinegar are all carbohydrates. It shows that a tendency of Korean people too much take a carbohydrates. Now and then, there are no special difference of winter over pass for vegetables, fruits, dried beef, dried fish and salt fishes. In yi dynasty, there are 62 kinds of table ware and cooking kitchen utensils, but many of them come to uselessness. 19 kinds of measuring unit are very non-scientific because that is not by weight but by bulk or volume. There are many food making terms which are 198 kinds of prepared cooking term, 11 kinds of cutting term and 20 kinds of boiling term. And 10 kinds of expression of taste can see this book.

Conventional polishing of stone panel edges has been done by hand. While this has changed somewhat with the advent of automatic machines, it is still very much a hand finishing technology. For the development of edge shape milling tool, the primary test on characteristics of edge shape milling tool was carried out. This paper presents the results of tests focused upon the milling capability that was varied by the variables of operation parameters. Author tried to confirm the effect of six operation parameters of equipment such as rotation speed, advance speed, applied load, water flow rate and rotational direction. The result from test was described in term of shape milling capability that was defined as cutting volume of rock by unit weight of tool wear. The variance of the results could indicate the optimum level of each operating parameters. The test was also carried out to determine the abrasion resistance varied according to the abrasive flow rate. The abrasion resistance was increased with the abrasive flow rate, but over some rate it was not changed.

Background: Meloxicam is used widely for exotic animal analgesia, but its toxicity in common raptor species in Thailand is unclear. Objectives: This study evaluated the single-dose effect of intramuscular meloxicam in common raptor species in Thailand for short-term and long-term periods. Methods: Twenty-two raptors were administered a single 1 mg/kg dose of meloxicam individually via intramuscular injection. The following were evaluated: clinical appearance, body weight, body condition score, body temperature, fecal appearance, complete blood cell count, and biochemistry panel before (day 0) and after the injection (1, 7, and 30 days). The collected samples were categorized into three groups: Brahminy kite (Haliastur indus) (n = 10), adult Barn owl (Tyto javanica) (n = 4), and juvenile Barn owl (n = 8). Results: None of the raptors in the study groups showed any abnormalities. The hematological profiles were significantly different in the short-term period (day 1 and day 7). The creatinine, aspartate aminotransferase, and creatinine kinase increased in several groups. On the other hand, the packed cell volume decreased in the Brahminy kite and juvenile Barn owl groups. According to the findings, an intramuscular injection of 1 mg/kg meloxicam affected the blood biochemistry panel of the muscle, but the affected raptors recovered within one week. Conclusions: An intramuscular injection of meloxicam at a single 1 mg/kg dose in Brahminy kites and Barn owls was not associated with the morbidity, hepatotoxicity, gastrointestinal toxicity, and nephrotoxicity in the short- and long-term periods.

A dust explosion is a phenomenon of strong blast wave propagation involving destruction which results from dust pyrolysis and rapid oxidation in a confined space. There has been some research done to find individual explosion characteristics and common physical laws for various dust types. However, there has been insufficient number of studies related to the heat of combustion of materials and the oxygen consumption energy about materials in respect of dust explosion characteristics. The present study focuses on the relationship between dust explosion characteristics of wood dust samples and oxygen consumption energy. Since it is difficult to estimate the weight of suspended dust participating in explosions in dust explosion and mixtures are in fuel-rich conditions concentrations with equivalent ratios exceeding 1, methods for estimating explosion overpressure by applying oxygen consumption energy based on unit volume air at standard atmospheric pressure and temperature are proposed. In this study an oxygen consumption energy model for dust explosion is developed, and by applying this model to TNT equivalent model, initial explosion efficiency was calculated by comparing the results of standardized dust explosion experiments.

The purpose of this study was to estimate the sodium and potassium intakes and their metabolisms of preschool children, and to evaluate the relationship between the blood pressure and the related variables. The subjects consisted of ninety-five preschool children aged two to six years (male 57, female 38). Twenty-four hour urines of subjects were collected for the measurements of their volume, sodium, potassium, creatinine and urea nitrogen. At the same time, the questionnaire was designed to assess the sodium and potassium intakes. The' results obtained were as follows; 1) The urinary excretion of sodium in 24 hours was 54.6$\pm$22.4mEq(orI255.8mg)and dietary sodium intake was 2147.0$\pm$518.4mg. The dietary sodium intake significantly increased with increasing age(p=O.0151). However, daily sodium intake per unit body surface area did not show significant difference by age. 2)The urinary excretion of potassium in 24 hours was 14.2$\pm$7.6 mEq (or 555.2mg) and the potassium intake was 1133.8mg. 3) The urinary excretions of creatinine and urea nitrogen were 240.2$\pm$126.2mg and 2946.7$\pm$1693.9mg, respectively. 4) The principal food SOUTce of sodium intake was the seasoning group, which con\ulcornertributed 49.9% to total sodium intake. 5) The main food source of potassium intake was milk and milk products; from which 28.6% of total potassium intake was obtained. 6) The blood pressure showed highly positive correlations with height, weight and body surface area (p$\leq$O.OOl) . In addition, the blood pressure was found to be correlat\ulcornered with urinary sodium excetion and dietary sodium intake (p$\leq$O.Ol).

In this study, hygroelastic behavior of thermosetting epoxy is predicted by molecular dynamics simulations. Since consistent exposures to humid environments lead to macroscopic degradation of polymer composite, computational simulation study of the hygroscopically aged epoxy cell is essential for long-time durability. Therefore, we modeled amorphous epoxy molecular unit cell structures at a crosslinking ratio of 30, 90% and with the moisture weight fraction of 0, 4 wt% respectively. Diglycidyl ether of bisphenol F (EPON862) and triethylenetetramine (TETA) are chosen as resin and curing agent respectively. Incorporating equilibrium and non-equilibrium ensemble simulation with a classical interatomic potential, various hygroelastic properties including diffusion coefficient of water, coefficient of moisture expansion (CME), stress-strain curve and elastic modulus are predicted. To establish the structural property relationship of pure epoxy, free volume and internal non-bond potential energy of epoxy are examined.

Research on FA(Fly ash) is actively carried out, while the research on BA(Bottom ash) is not so, and research on BA recycling field is urgently required. Therefore, in this study, we investigated the lightweight and thermal insulation characteristics of BA mortar by comparing BA mortar made with porous dry BA(air-cooled) and general mortar. To investigate the lightweight of BA, density test, unit volume mass test and SEM(Scanning Electron Microscope) test were performed. BA mortar and general mortar molds were prepared for the thermal insulation test at room temperature and humidity environment determined by KS A 0006 and they were dried at the temperature of $105{\pm}2^{\circ}C$ until the weight became constant. As a result of the lightweight test, the lightweight of BA mortar is about 30% lighter than the general mortar. Therefore, BA is expected to contribute to reduce the building load when used as building material. As a result of thermal insulation test, the thermal conductivity of BA mortar is about 30% better than that of general mortar.

This study investigated the best condition when mixed sand with a river and crushed sand was used though the experiment for the properties of the concrete corresponding to the control of fine aggregate ratio to apply the mixed sand and properties of the fine aggregate at the ready-mixed concrete factory on Yeongnam and Honam. The physical properties of Yeongnam and Honam is satisfied with KS F 2526 and KS F 2527 except fineness modulus and passing amount of 8mm sieve. And, the mixed sand above two types which were incongruent to use individually was being used at each factory, and it was managed in accordance with KS. The flowabillity of the mixture proportion of concrete which was estimated by method of unit volume weight according to the fine aggregate ratio at each factory on Yeongnam and Honam was higher than existing mixture proportion. It was analyzed that the residual water due to decline of the surface area caused by reducing fine aggregate ratio was increased relatively. Accordingly, it was considered that the effect on the economic mixture proportion and improvement of durability might be possible.

In this study, the mechanical properties of early-age concrete were evaluated by mixing the electric arc furnace oxidizing slag fine aggregate with 30% and 50% replacement ratio. Slump test, air content test and unit volume weight test were performed for fresh concrete, and compressive strength test and chloride penetration experiments were carried out in hardened concrete. The compressive strength increased up to 7 days of curing age with increasing replacement ratio of the electric furnace oxidizing slag, but the strength decreased to 90% level of OPC concrete at 28 days of age. Regarding the result of chloride penetration test, no significant differences from OPC concrete were evaluated, which shows a feasibility of application to concrete aggregate.
