High speed ball end milling is attracting interest in the aerospace industry for the machining of complex 31) airfoil surfaces in nickel based superalloys, Experimental work is detailed on the effect of cutter orientation on tool life, cutting forces, chip formation, specific force and workpiece surface roughness, when high speed ball end milling nickel based supperalloy(lnconel 718). Dry cutting was performed using 8min diameter solid carbide cutters coated with either TiA1N or CrN for the workpiece mounted at an angle of 45˚ from the cutter axis. A horizontal downwards cutting orientation provided the best tool life with cut lengths~50% longer than for all other directions. Evaluation of cutting forces and associated spectrum analysis of results indicated that cutters employed in a horizontal downwards direction produced the least vibration.

In this research, to develope the A1 7075/CFRP multilayered hybrid composites, CRALL(Carbon Reinforced aluminum lamiate) specimens were processed by autoclavecuring system that curing temperature, time, surface pretreatment condition of aluminum were constant. Andthe fatigye life and failure mechanism on CFRP volume fraction and fiber orientation of CRALLspecimens were investigated. A fatigue life was greatly influenced by effect of CFRP fiber volume fraction but it was less effected than those of fiber orientation. The fatigue failure arised from interface delamination of CFRP and aluminum sheet after shear fracture of aluminum layer. The failure mechanism is assumed that the aluminum laminates which divide the CFRP into many thim layers tend to arrest the failure propagation.

High-speed machining generates concenter thermal/frictional damage at the cutting ed rapidly decreases the tool life. This paper I at determining the effect of cutter orienter the cutting environment on tool life, tool mechanism when down milling. In this paper, experiments were carried out in various tool and cutting environments, such as dry, wet compressed chilled air, tool life were measu evaluate machinability in high-speed milli difficult-to-cut material and die steel, Tool measured in horizontal upwards, horiz downwards, vertical upwards and vert downwards. In addition, tool life was measur dry, wet and compressed chilled air. For this a compressed chi1led-air system was manufact The results show that a horizontal cutter ori provided a longer tool life than a vertical orientation. With respect to the cutting envi compressed chilled air increased tool life. H the wet condition decreased tool life due thermal shock caused by excessive cooling high-speed mill ins and the compressed chilled had little effect.

The relative extrinsic value orientation (REVO) means the relative importance to extrinsic values (e.g. wealth, fame and social approval) compared with intrinsic values (e.g. affiliation, self-acceptance and personal growth). This study aimed to investigate the causal relation between REVO and life-satisfaction using the auto-regressive cross-lagged modeling. For this purpose, 3rd, 5th, and 7th year data from the Korea Children and Youth Panel Survey (KCYPS) middle school 1st grade panel was analyzed (N = 2,259; 1,140 males and 1,119 females). The results are as follows; Firstly, positive auto-regressive effects of REVO and life-satisfaction were significant. Secondly, REVO was found to have negative and cross-lagged effect on life-satisfaction. However, cross-lagged effect from life-satisfaction to REVO was not significant. Finally, no gender difference was found in this relationship. These results suggest that low life satisfaction does not cause the relative extrinsic value orientation, but high relative extrinsic value orientation may cause low life satisfaction.

Despite the recent increase in the prevalence of the franchise system in the foodservivce industry is increased recently, the its variation the exigencies of the industry itself requires that franchise systems to be fully equipped with various a variety of business strategies which is indispensable to run franchise system. In the previous studies, most the majority of researchers have been likely to gathered samples from only one region, or all from a similar type of business. However, considering the difference between Seoul and other areas or categories of business type, there could be may be differences different with in these conditions (market orientation, transaction specific assets, environmental dynamic, and trust and trust). Therefore, the principal objective of this study aims was to verify the differences among areas and categories of franchise business. The results of this article are as follows : the variables of customer orientation, competitor orientation, environmental dynamics, and trust and transaction- specific assets show evidence regional differences (p<0.01), and these variables are differ significantly different by category of business (p<0.05). However, the present paper is limited in its scope. Further studies on into different largesclae assessments are needed required.

This study investigated causal relationships between goal orientation, sales and performance towards increasing the effectiveness of up-selling in internal promotion methods in family restaurants and provided implications about the hiring and training of sales people. The subjects were 232 sales people in family restaurants. The data were collected by self-administered questionnaires and analyzed by exploratory factor analysis, reliability analysis, comparative analysis of the average, and regression analysis. Results, showed that variations in goal orientation, sales, and performance depended on the age and experience of salespeople and that goal orientation makes adaptive selling more effective. It turned out that effort selling affects up-selling result than adaptive selling. Long-term workers were better than short-term workers in goal orientation, selling, and up-selling results, so human resource management needs to implement a long-term plan to enhance these effects. And, because effort selling is more effective than adaptive selling in up-selling results in family restaurants, effort selling requires training.
