In this paper, we aim to estimate two scale-parameters of exponentiated Pareto distribution (EPD) based on lower record values. Record values arise naturally in many real life applications involving data relating to weather, sport, economics and life testing studies. We calculate the Bayesian estimators for the two parameters of EPD based on lower record values. The Bayes estimators of two parameters for the EPD with lower record values under the squared error loss (SEL), linex loss (LL) and entropy loss (EL) functions are provided. Lindley's approximate method is used to compute these estimators. We compare the Bayesian estimators in the sense of the bias and root mean squared estimates (RMSE).

The purpose of this study was to measure consumption values and to investigate the differences in the process of decision making when purchasing apparel products among groups divided by consumption values. A self-administered questionnaire was distributed to 550 subjects in their 20's and 30's from Sepember 29th to October 25th in 2001; 463 were used for the data analysis. The results of this study were as follows; Consumption values were classified into five factors: Practical/functional value, Social/conformitive value, Subjective/aesthetic value, Epistemic value and Conspicuous value. Subjects were classified into 4 groups based on consumption values: the Conspicuous, the Epistemic, the Social/conformitive and the Indifferent. There were significant differences among the four groups in selected motives in the problem recognition process. Significant differences were found among the groups in own taste & personality in the information search process. Significant difference were also found in the importance of design, color, price, coordination, fashion and self-image in the alternative evaluation process.

The purpose of this study is to evaluate work values of hospital employees. Their work values was compared with that of other corporate's employees or among that of specialties in hospital. It was surveyed to 893 persons; 164 in hospital and 709 in others. The work values of hospital employees are similar to that of other corporate's employees. But they have first priority to working environment, and emphasize monetary incentive much more than hierarchical development. There are some gap in work value between age groups in hospital, different from other corporate. That means hospital manager need to development the more developed work value in hospital. The work values are different in monetary incentive, hierarchical development, safety, working environment, creativity among specialties in hospital. The more special employees emphasize much more to monetary incentive, hierarchical development, working environment and the less special employees have priority to safety work value. Specially, because the hospital managers want to have safety than creativity, it must to make some changing program of work value for advance of future hospital.

The purposes of this study were to examine the fashion adopted by young women in the United States in the 1970s and to explore how the dynamic shifts toward feminist values influenced those fashion trends. Fifteen American women who were college students in the 1970s were interviewed for the study. Throughout the decade, casual and comfortable styles became more prevalent; for example, pants became widely accepted for formal occasions as well as informal occasions due to an overall emphasis on practicality. The feminist and civil rights movements along with more liberal attitudes toward religion were among the more dominant cultural values that influenced the respondents' choices in clothing styles. Feminist presentation was diverse extreme or eclectic - and constantly renegotiating itself. This study helped us better understand the dynamics involved between fashion and value changes as well as the influence of feminism on the 1970s fashion in the United States.

We need a lot of manpower and we can cut down a labor cost by applying industrial robots the footwear bonding automation process. In this study, we suggest how to program off-line robot path along a shoe's outsole shape in the footwear bonding process by 5-axis microscribe system like robot arms. This microscribe system development consists 5-axis microscribe mechanics, signal processing circuit, and PC with software. It is the system for making database of a shoe's outsole through the movement of a microscribe with many joints. To do this, first read 5-encoders' pulse values while a robot arm points a shoe's outsole shape from the initial status. Then, calculate a relative shoe's outsole by Denavit-Hatenberg's (D-H) direct Kinematics of known length of links and coordinate values. Next, calculate the encoders' pulse values of the robot arm's rotation and transmitting the angle pulse values to the PC through a circuit. Finally, it is able to display a shoe's outsole at real-time by computing the Denvavit-Hantenberg's (D-H) direct kinematics in the PC. With the coordinate values calculated above, we can draw a bonding gauge-line on the upper. Also, we can make off-line robot path programming compute a shoe's bonding area on the upper. These results will be effectively applied for programming a robot path on off-line and automatically.

Adequate nutrition is important in maintaining optimal health. Malnutrition can expose individual to increased risks of morbidity and mortality. The purposes of this study were to determine the basal energy expenditure (BEE) of Korean healthy subjects and TPN patients using Bioelectrical Impedance Analysis (BIA) method and to compare these values with those predicted by Harris-Benedict equation (H-B). BEE values measured by BIA were compared with predicted BEE values by the H-B formula in 59 clinically stable TPN patients and 65 healthy volunteers. In healthy volunteers and TPN patients, statistically significant differences were not shown between the BEE values measured by BIA (1392.5 Kcal and 1325.9 Kcal) and those predicted by H-B formula (1384.1 Kcal and 1270.1 Kcal). In male volunteers, statistically significant differences were not shown between BEE values measured by BIA (1670.7 Kcal) and the H-B formula (1550.9 Kcal), but in female volunteers, statistically significant differences were shown between BEE values measured by BIA (1194.8 Kcal) and the H-B formula (1265.6 Kcal). In male TPN patients, statistically significant differences were shown between BEE values measured by BIA (1453.5 Kcal) and the H-B formula (1335.9 Kcal), but in female TPN patients, statistically significant differences were not shown between BEE values measured by BIA (1126.4 Kcal) and the H-B formula (1167.2 Kcal). In normal healthy volunteers, $90.8\%$ of BEE values measured by BIA and in TPN patients $89.8\%$ of BEE values measured by BIA were within $15\%$ of BEE values predicted by the H-B formula in non-obese subjects. In conclusion, BEE values predicted by H-B formula or measured by BIA can be applied to non-obese Koreans. However, these values should be confirmed with Indirect calorimetry for Koreans.

The Maneuvering Indices of a ship are the values that decide the quantity of her motion in turning when her rudder is turned over to an angle to the starboard or the port. They consist of two kinds of indices, one of which is called index K and the other, index T. Index K decides a ship's turning ability and index T does the length of time delay of a normal turning motion after her rudder has finished the turn of an ordered angle. Generally, the values of the indices are calculated through some mathematic formulas with figures of her heading degrees recorded at a fixed time intervals during her Z test. The values of the same kind index of a ship appear differently according to the ship'sspeed, trim, rudder angle and loaded condition, etc. In this paper, the author analyzed all the amthematic formulas required to calculate the values of the indices in their forming process and examined them from the point of mathematics and dynamics and also actually figured out the values of maneuvering indices of the M.S. "HANBADA", the training ship of Korea Merchant Marine College through her Z test. The author supposed a case in which two same typed ships as the "HANBADA" in size, shape and conditions were approaching each other in meeting end on situation and each ship turned her rudder hard over to the starboard respectively when they approached to the distance of 3 times as long as the ship's length. The author worked out mathematic formulas calculating forward and transverse ship's motions within the above mentioned situation for the quantative analysis of the collision avoding action to certify whether they are in collision status or not. Applying the calculated values of the maneuvering indices of the "HANBADA" to the motion calculating formulas, the author found out the two ships were passing over each other with the clearing distance o 39m between their port quarters. With the above mentioned examinations and explanations, the author demonstrated that a ship's motion in any collision avoiding action can be shown with quantities of time and distance within reliable limit.istance within reliable limit.

The new types of phosphazene diagnostic membranes have been prepared for blood glucose measurements. The possible interferents in human blood were sorted into 4 different series and their effects on the glucose measurements were examined. In case of series I which indicates the lowest concentration, most of them did not show any serious effects on the blood glucose measurements, but only ascorbic acid (AA) showed 5~8% higher values compared to K/S values of the standard solution. In case of series II, all of four interferents showed 3~4% lower K/S values than those of plasma, but they showed consistent values by concentration variation. In case of series III, all of three interferents did not show any big differences compared to the standard solution. In case of series IV which indicates the highest concentration, two interferents showed 11~15% lower K/S values than the standard values, however they did not any serious effect on the blood glucose measurements.

We tried to investigate the effects of substituent position, temperature, and additives such as NaCl and n-butanol on the solubilizations of cresol isomers by tetradecyltrimethylammonium bromide (TTAB), using the UV-Vis spectrophotometric method. The measured solubilization constants (K_s) values for each cresol isomer increased in the order o-cresolo and ∆H^o values for the solubilizations of cresols were all negative values but the ∆S^o values were all positive values within the measured ranges. The values of ∆G^o increased also with increasing the concentration of n-butanol but decreased with increasing the concentration of NaCl. From these facts, we could conclude that both the enthalpy and entropy changes contribute together for the solubilizations of cresols isomers by cationic surfactant of TTAB and they are solubilized in the polar palisade region or at the surface of micelle.
