  • This paper is experimental study of machining characteristics about martensitic heat resisting steel STR11. Machining characteristics are different according to internal quality(chemical compositions, microscopic structure and nonmetallic inclusion) mechanical properties(tensile strength value impact value and hardness) and dynamic cutting force. Following are the results : 1. In analyzing internal quality test materials have typical martensite structure and a minute needle-shaped structure. 2. Tensile strength and reduction of area and hardness are larger. But values of elongation and impact values are smaller. Fracture surface of tensile specimen is ductile. 3, Cutting force is decreasing with cutting speed increasing 4. Cutting force is increasing with feed speed increasing.

  • In this paper, we have studied internal quality including chemical compositions, microscopic structure and nonmetalic inclusion of test materials. We have analyzed machining characteristics including tensile strength value, impact value, hardness value etcs. Test materials are usd martensitic heat resisting steel, STR11 and STS420J2. The obtined results are as follows : 1. In analyzing internal quality, STR11 and STR420J2 have typical martensite structure and a minute needle-shaped structure. 2. Tensile strength and reduction of area and hardness value are large STR11 than STS420J2. But elongation impact are smaller STR11 than STS420J2. 3. Fracture surface of tensile speciman is ductile in STR11 and STS420J2.

  • Purpose : The purpose of this study is to understand the attitudes to internal service quality between coworkers, service quality to patients, job satisfaction, organizational identification and job identification of physical therapists in medical organizations. Methods : Data were collected from physical therapists working in medical organizations. 195 questionnaires were analyzed. Participants' total mean, group mean by age, sex, career and type of medical organization and the variables' correlations were examined. Results : The attitudes of physical therapists to five variables were very positive. Especially job identification was strong. The significant differences between groups were found in some variables. All variables except age and career were positively related to each other. The correlation between age and career was very high. Age and career were related to some of variables. Conclusion : To improve organizational performances it should be a top priority to understand the attitudes of physical therapists in organizations.

  • The present study was conducted with the aim of investigating the effect of storage length, turning frequency and egg position on internal quality traits of chukar eggs obtained from 56-week-old chukar partridges under the same nutrition and management conditions. A total of 720 eggs were collected and assigned to 36 subgroups according to storage length (7, 14, 21, and 28 d), turning frequency (0, 1, and 24 per day) and egg position (pointed end up, blunt end up and horizontal). As a result of the study, almost all the internal quality traits of chukar eggs were negatively affected by lengthening of storage period especially 21 days and longer (p < 0.001). Internal egg quality traits weren't statistically affected by turning frequency except yolk index (p < 0.01). An improvement was observed in Haugh unit, albumen index and heigh of eggs stored with pointed end up (p < 0.001). Some significant interactions occurred among all internal egg quality traits which were mostly dependent on the eggs stored horizontally, extended storage time more than 21 days and egg turning during storage. The results and interactions showed that internal quality traits would be preserved well for the eggs stored less than 21 days with the position of pointed end up independent of turning. If the storage period was to exceed 21 days, the eggs should be positioned horizontally and turning should be applied to preserve the quality of chukar eggs.

  • In this study, the basic concept of service profit chain was introduced based on the existing studies related to service quality of airline ground crew to find out how are customer satisfaction influenced by factors related to employees who provide service quality to the customers, such as internal service quality and job satisfaction. The data of this study was collected by questionnaire and based on airline ground crews and Gimpo international airport users. A total of 190 of airline ground crew and 273 of passengers validity sample was analyzed a frequency analysis, reliability analysis, exploratory factor analysis and correlation coefficient analysis from SPSS 21, a hypothesis through out confirmatory factor analysis and structural equation modeling from AMOS 7.0. As a result of the analyses, it was found that the models was appropriate in proving the hypotheses on interrelationships among internal service quality, job satisfaction and customer satisfaction. Overall, finding of this study enhance the theoretical progress on the experiential concept in walking tour and offer important implication for airline industry marketers.

  • The purpose of an internal control system is to prevent the occurrence of errors and fraud in the process of producing accounting information, thereby providing investors with reliable information. For the effective operation of an internal control system, it is necessary to secure a sufficient number of personnel and experienced staff. This study focuses on the personnel directly involved in producing accounting information, examining whether companies that invest in their internal control staff experience a mitigation in the phenomenon of valuation errors. The analysis revealed that the size and experience months of the personnel responsible for internal control have a significant negative relationship with valuation errors. This result implies that by securing sufficient personnel for the smooth operation of the internal control system and placing experienced staff within the system, investors can effectively make judgments about the intrinsic value based on quality accounting information, thereby reducing valuation errors.

  • This paper reviewed the relationship between boundary spanning behaviors and service quality, and the moderating effect of gender. Based on the responses from 204 employees in outdoor-food franchising system, hierarchical regression analysis showed that service delivery has positive relationships with all service quality factors, and external representation and internal influence have partly positive relationship with them. Gender appeared to have partly moderating effect on the relationship between only internal influence and service quality.
