This study attempted to investigate the difference in service orientation according to the individual characteristics of hair salon workers, and to identify the internal marketing factors of hair salon that influence service orientation. Questionnaires for empirical research were collected from hair salon workers in Gyeongnam, and the results of analyzing the collected questionnaires through IBM SPSS Statistics 26 are as follows. First, as a result of analyzing the difference in service orientation according to the individual characteristics of hair salon workers, the '40s or older' group and the 'working period of 10 years or longer' group showed statistically higher service orientation than other groups. Second, as a result of analyzing the causal relationship between internal marketing and service orientation, it was found that welfare, compensation system, education and training of internal marketings had the statistical effect on service orientation, and in particular, the compensation system had the strongest effect on service orientation. Therefore, service orientation for customers should be improved through internal marketing activities that take into account the individual characteristics of hair salon workers. The improvement of service orientation means the customer's intention to reuse, suggesting that ultimately the management performance of hair salon companies can be further improved.

The purpose of this study sought to examine the mediating effect of social support in the relationship between adolescents' family strength and school life adjustment. For this purpose, a survey was conducted from May 2023 to June 2023 on youth attending middle and high schools in Daegu and Gyeongbuk, and statistical analysis was performed on the data of 768 people without missing data using SPSS 21.0 program. The results of this study were as follows. First, the family strength perceived by adolescents was found to have a significant positive effect on school life adaptation. Second, the family strength perceived by adolescents was found to have a significant positive effect on social support. Third, social support was found to have a positive and significant effect on school life adaptation. Fourth, social support showed a partial mediating effect in the relationship between adolescents' perceived family strength and school life adjustment. These research results have implications in that they provide empirical evidence to help adolescents adapt well to school life based on healthy family relationships. In addition, we hope that this will serve as a practical basis for the use of parent education programs and family counseling programs that help adolescents adapt well to school life by eliciting social support through positive family functions at home.

The purpose of this study was to investigate the somatic symptoms, trait anger, and anger expression styles perceived by cancer patients, examine their relationships, and identify variables influencing somatic symptoms. The mean of patients' somatic symptoms was 8.59 ± 5.34, trait anger was 1.78±0.53, and anger suppression was 2.02±0.36, which is the highest. In terms of differences in somatic symptoms according to the general characteristics of the subjects, stage 3 cancer stage was the highest compared to other stages(F=2.745, p=.045), and the presence of cancer-related pain was significantly higher compared to its absence(t=5.046, p<.001). Differences in trait anger according to the general characteristics of the patients were found to be significant based on monthly income(F=3.952, p=.004). Differences in anger expression styles were found by age(F=4.186, p=.017), monthly income(F=3.302, p=.012), and experience of cancer-related pain(t=2.715, p=.007) in anger suppression, while differences were observed by age(F=3.637, p=.028), employment status(t=2.563, p=.011), monthly income(F=3.580, p=.008), and duration of treatment(F=3.726, p=.026) in anger regulation. The somatic symptoms perceived by the patients had positive correlations with trait anger(r=.209, p=.006), anger suppression(r=.206, p=.006), anger expression(r=.199, p=.008), and anger regulation(r=.194, p=.009). It was found that a greater presence of cancer-related pain was related with a higher level of somatic symptoms of patients among other variables.

Heat pump unit performance is represented by the COP(Coefficient of Performance) and expressed by the one point design condition according to KS C 9306. However, when heat pump operated to the real buildings, the simulations are changed continuously according to the actual weather conditions, the building load and heat pump source conditions. The purpose of this paper is to evaluate the APF(Annual performance factor) for a climate dependent building integrated air-to-air heat pump system in major cities in Korea. TRNSYS simulation tool with an international MV standard based IPMVP 4.4.2 was utilized to perform the annual performance analysis. The APF with the multi-performance data based method was calculated as 2.29 for Daejeon residential building case while Busan residential building case appeared as the highest with 2.36.

In the era of globalization, small and medium sized businesses (SMBs) are striving to attain competitive advantage in the rapidly changing and diversified markets. It is necessary for SMBs to enhance their global compentency in order to successfully enter overseas markets. In an attempt to shed light on how closely an SMB's global competency is related to how efficiently their employees can perform their tasks in the overseas market, this study examined the nature of English use in oral communication by twelve Korean men working in Dubai. Questionnaires and recordings were used to collect the data. The results show that English competency plays a crucial role in work efficiency in the overseas business context. Also, superior oral skills are considered the most important in doing business as it is the most frequently required form of communication. Participants of the study showed a tendency to make up for their lack of communicative competency by using various strategies. They tried to avoid communication breakdown by all means in order to get the task done.

This study aims to investigate human capital in Korea's online game industry (as the representative of IT-based creative services) under the knowledge-based economy paradigm. In recognition of the importance of intellectual capital closely intertwined with human capital and the economic potential of the online game industry, Korean government has begun to show active support. In this context, this study measures the human capital efficiency in online game business by using non-parametric analysis (Data Envelopment Analysis, DEA). Most previous studies (human capital theory, knowledge based economy theory, economic growth theory) have proved that human capital has a very positive effect on sustainable growth of corporate management and wealth of nations. As such, this paper uses the DEA to obtain the efficiency of the human capital (scale, investment, education, compensation). The results of this study will suggest strategic implications on maximizing the human capital in online game corporations and provide a reference frame for government policies.

We have developed the digital radiography system applied by the one dimensional multiwire proportional chamber. X-ray position signals were obtained from anode wires which were connected to counters through amplifiers and discriminators. The chamber was made of gas flow type and detector gas was P10. The threshold voltage which gives to the discriminator is independent on the neighboring channels. This improved the uniformity of the detector. Then the differential nonlineality is ${\pm}4%$. Increasing the gas pressure, the spatial resolution is about 1.4-mm at which the pitch of the anode wire is 2-mm. The object is scanned in vertical direction to take an image. The number of pixels in the image is $32{\times}32$.

The PMIPv6 is a network controlled mobility management protocol in which mobile nodes never participate in IP mobility protocol signaling. One issue in using PMIPv6 for multicast service is that a new component should be added as the mobility management functions are located not on the device but on the network. Currently, standardization activities for providing muticast services with PMIPv6 have been actively in progress. This paper addresses some issues about the on-going standardization works for providing efficient real-time multicast services with PMIPv6, and proposes a scheme for minimizing hand over delays and packet losses by using a new neighbor cell reporting method. The proposed scheme has been verified to outperform the existing scheme in hand over delay and packet loss perfonnrmces by using computer simulations.

Due to the requirement of the development of the precision manufacturing industry, the accuracy of machine tools has become a key issue in this field. A critical factor that affects the accuracy of machine tools is the feed system, which is generally driven by a ball screw. Basically, to improve the performance of the feed drive system, which will be thermally extended lengthwise by continuous usage, a thermal error compensation system that is highly dependent on the feedback temperature or positioning data is employed in the machine tool system. Due to the overdependence on measuring technology, the cost of the compensation system and low productivity level are inevitable problems in the machine tool industry. This paper presents a novel feed drive thermal error compensation system method that could compensate for thermal error without positioning or temperature feedback. Regarding this thermal error compensation system, the heat generation of components, principal of compensation, thermal model, mathematic model, and calculation method are discussed. As a result, the test data confirm the correctness of the developed feed drive thermal error compensation system very well.

The Ag-treated activated carbon was prepared by the impregnation of Ag on the home made activated carbon. We investigated the nitrogen adsorption property, surface structure, and antibacterial activity of the carbon. The BET surface areas of Ag impregnated activated carbon are distributed to $740-1112.2m^2/g$ region. The results of nitrogen adsorption property show that BET surface areas move gradually to lower value with increasing $AgNO_3$ mole concentration. From the SEM results, we observed window blocking effect for micropores of external surface of adsorbent by Ag impregnation. Escherichia coli which is a kind of colon bacillus was used as bacteria for antibacterial test. From these results, we also observed that activity increase gradually to larger range with increasing $AgNO_3$ mole ratio.
