A study was carried our to investigate the characteristics of physico-chemical components palatability of cooked rice accoring to different transplanting time. The treatments were consisted of five transplanting time, from May 5 to July 5 at 15 -day intervals, and six cultivars ; two early-maturing, two mid-maturing and two late-maturing cultivars which are clearly identified by evaluation of cumulative temperature and growth duration from seeding to heading of rice plants. In gelatinization characteristics of rice grain, alkali digestion value was low in the earlier transplanting regardlessof maturing types. Initial pasting temeprature maximum viscosity and breakdown as amylogram charcteristics were high at the transplanting of June 5. The palatability of cookedrice was evaluated that early-maturing cultivars were much better in early transplanting than in late transplanting . The optimum transplanting time for palatibility was the periods from May 5 to 20 in early maturing varieties, May 20 to June 5 in mid-maturing and June 5 to June 20 in late-maturing ones at Honam district in Korea.

The aim of this study was to compare the growth performance, fiber characteristics of the pectoralis major muscle, and meat quality characteristics in the heavy weight (HW) and random bred control (RBC) quail lines and genders. The HW male exhibited more than two times greater body (245.7 vs 96.1 g, p<0.05) and pectoralis major muscle (PMW; 37.1 vs 11.1 g, p<0.05) weights compared to the RBC female. This growth performance in the HW line was associated with a greater muscle fiber area (1,502 vs $663.0{\mu}m^2$, p<0.001) compared to the RBC line. Greater muscle mass of the HW male was accompanied by a higher percentage of type IIB fiber compared to the HW female (64.0% vs 51.0%, p<0.05). However, muscle fiber hyperplasia (increase in fiber number) has had a somewhat limited effect on PMW between the two lines. On the other hand, the HW line harboring a higher proportion of type IIB fiber showed rapid pH decline at the early postmortem period (6.23 vs 6.41, p<0.05) and lighter meat surface (53.5 vs 47.3, p<0.05) compared to the RBC line harboring a lower proportion of type IIB fiber. There were no significant differences observed in the measurement of water-holding capacity including drip loss (2.74% vs 3.07%, p>0.05) and cooking loss (21.9% vs 20.4%, p>0.05) between the HW and RBC lines. Therefore, the HW quail line developed by selection from the RBC quail, was slightly different in the meat quality characteristics compared to the RBC line, and a marked difference was found in growth performance between the two quail lines.

This experiment was conducted to investigate the effect of Cordyceps militaris with probiotics (CMP) supplementation on the growth performance, meat quality and storage characteristics, and cordycepin content in the meat. Sixty one-day-old broilers (Ross 308) were allotted to two treatment groups of 30 each. In addition, six broilers were randomly assigned to a cage in the two treatment groups. The two dietary treatments were as follows: Control (CON) and basal diet + 0.5% of CMP. Body weight and feed intake were measured on the 1st, 14th, and 28th days from the start of the experiment. On days 1 - 14, the supplementation of CMP improved (p < 0.05) the body weight gain (BWG) and feed conversion ratio (FCR). Additionally, the feed intake (FI) and FCR scores in the CMP groups improved (p < 0.01) compared to the CON during the entire period. For the meat quality characteristics, water holding capacity (WHC), cooking loss (CL), redness (a^*) in meat color value, and shearing force (SF) for the CMP group were improved (p < 0.01) compared to the CON group. For the meat storage characteristics, pH and thiobarbituric acid reactive substances (TBARS) were improved (p < 0.01) when the broilers were fed CMP compared to the CON group. Broilers fed CMP had a higher (p < 0.01) cordycepin content in the meat compared to the CON group. In conclusion, CMP improves the growth performance and meat quality of broilers.

This study was conducted to analyze the wearing practice and the purchasing characteristics of household rubber gloves in order to obtain the product demands for quality improvement. The effects of wearing time per day and demographic characteristics on those were evaluated. A questionnaire was developed and administered to 494 housewives. Statistical tests such as descriptive analysis, crosstabs, factor analysis, one-way ANOVA, were used to analyze the data. The results indicated that housewives were largely divided into two groups according to the wearing time per day. One group wore gloves more than 3 hours a day, while the other wore less than 3 hours. We found that there were significant differences in the wearing practice and the purchasing characteristics between these two groups. It showed that the quality improvement of household rubber gloves should be achieved in a point of view of the comfort feeling and easiness in wearing and taking off. The housewives showed positive attitude toward pliability and necessity, while negative altitude toward dryness, comfort and mobility in wearing. The household rubber gloves were identified as the necessities which is so familiar and common that only a few of demographic characteristics have effect on.

Pile driving technique has been regarded as the most reliable way of constructing deep foundations. Engineers have long believed that the quality of the installed piles is a simple function of the set values which can easily be obtained from the field pile driving records. Consequently most of the local building codes are based on the dynamic formula. However it has been proven that the quality of the driven pile is influenced not only by the set values but also by various factors, such as hammer performance, helmet characteristics, time dependent geotechnical characteristics of the site, etc., from the results of various researches made during the last two decades. In this paper an appropriate quality control scheme has been proposed by taking various influencing factors into consideration.
