Effects of Social and Organizational Support on the Satisfaction of International Students and Career Commitment

Perceived organizational support and perceived social support affect individual performance. Their influence may or may not be the same depending on the situation. This study describes the different effects of perceived organizational support and perceived social support on organizational satisfaction and social life satisfaction. Furthermore, it proves that perceived organizational support and perceived social support enhance the organizational (school) satisfaction and social life (life of studying abroad) satisfaction of international students. On addition, through this process, they also increase the career commitment of students. This paper identifies the importance of perceived organizational support and perceived social support necessary to improve the international students' performance, and explain the impact and relevance of their different satisfactions. Through this, this article proposes ways to improve the performance of international students and the discriminatory relevance of perceptions of different objects.


Perceived support and satisfaction
POS has a positive role in improving performance such as satisfaction and commitment [14]. When the POS is high, the social and emotional needs of the members are satisfied. They consider themselves to be properly evaluated and recognized. In this case, the members think that the profit or loss of the organization is their own profit or loss. This internalization makes people more satisfied and committed in the organization [1]. On the other hand, when the POS is low, the members have the fear that the organization will exploit them. Thus, they will reduce efforts to improve business performance [3]. POS encourages members to increase their interest and loyalty as well as have a positive attitude toward the organization [15]. Hence, POS will inspire positive attitudes toward organizations such as schools and society. In this regard, the hypotheses about the effects of POS on SS and SLSA were established as follows: H1. POS will have a positive effect on SS. H2. POS will have a positive impact on SLSA.
Similar to POS, life satisfaction is closely related to satisfaction with organizations in their life. People who are socially recognized and supported are more likely to have a more positive attitude towards their society and organization. PSS will be more recognizable to members when social networking, such as smooth communication, operates positively. A positive attitude towards social networking can improve one's life satisfaction [12]. When an individual is satisfied with oneself, this person will be more satisfied with the organization one belongs to. Based on this relevance, the following hypotheses were established: H3. PSS will have a positive impact on SS. H4. PSS will have a positive impact on SLSA.

Career commitment
People feel committed to personal purpose for individual career development. Career commitment (CC) specifically means the people's motivation to work hard to achieve their careers. CC begins with the idea that people see careers as one of the most important elements in life. Workers with CC are contemplating what they can achieve in their jobs, and are successful and proud of their careers [16]. CC refers to a specific attitude towards the individual profession, job, or vocation [17]. A person with a high CC represents a high level of motivation and expectations in one's organization. They also are more satisfied, and motivated to work and have a higher commitment to organizations [18].
The effects of perceived support on CC through satisfaction Members with a high level of POS become more satisfied with their organizations [19], and this attitude of satisfaction increases the behavior of commitment [20]. Members who are satisfied with a particular organization are more motivated and tend to continue developing themselves. These members regard their organization as a structure that can meet social and psychological needs and, not simply a means of making money [21,22]. More satisfied members act for more goals and more actively participate in organizational activities than those who feel less satisfied [23]. This process will result in more commitment to their career due to satisfaction. Based on this relevance, the following hypotheses were established: H5. SS will mediate the relationship between POS and CC. H6. SLSA will mediate the relationship between POS and CC.
H7. SS will mediate the relationship between PSS and CC. H8. SLSA will mediate the relationship between PSS and CC.

Measurement and Participants
All items in this study were measured on a Likert 7-point scale. First, POS was measured by 4 items such as "This school would not ignore complaints from me" and "My school really cares about my well-being" [4]. Second, PSS was measured by 8 items, including, "Tell you that they appreciate your efforts", "Encourage you to do well" [6]. SS was measured by 6 items, involves "I enjoy being a student on this campus", "I feel comfortable at this university" [11]. SLSA was measure by 4 items, including " I am satisfied with my life", "In most ways my life is close to my ideal" [12]. CC was measured by 6 items such as "The ambitions in my life mainly have to do with my career", " I think that I should have a successful career" [16].
Data was collected from 164 Chinese international students studying in Korea. In terms of gender, there were 58 males (35.4%) and 106 females (64.6 %). In terms of age, 43 were 18-20 (26.2 %), 112 were 21-24 (68.3%), and 9 were older than 25 (5.5%). In regards to their length of employment, 14 had worked for less than 1 year (7.3 %), 62 had worked 1-5 years (32.5 %), 59 had worked 5-10 years (30.9 %), and 56. In regards to their length of study, 60 had studied for less than 1 year(36.5%), 74 had studied 1-2 years (45.1%) and 30 had studied more 2 years(18.4%) I. Analysis Results of the exploratory factor analysis(EFA) with vari-max rotation, confirmatory factor analysis(CFA), and reliability are present in table (1). Each variable has a significant validity and sufficient reliability.      Table (3), effect of POS was decreased (β=.569 to β=.255), and SS has significant effect (β=.530). Also, in Table (4), effect of POS was decreased (β=.569 to β =.303), and SS has significant effect (β=.456). These results mean that in the relationship between POS and CC, both SS and SLSA have a partial mediating effect. The Sobel test results also showed a significant mediating effect. Therefore, hypotheses 5 and 6 were adopted.  Table (5) and (6) display the results of mediating effect of SS and SLSA between PSS and CC. As a result, the influence of PSS on CC decreased from β=.597 to β=.314(SS) and β=.356 (SLSA). Also, it was found that SS(β=.504) and SLSA(β=.435) had a significant effect on CC. Moreover, the results of Sobel test showed significant mediating effects of SS and SLSA. Based on these results, hypotheses 7 and 8 were adopted.

Conclusion
Results and implications SS represents the organization such as the university. It has been shown that POS (.44), which is related to the organization, has more influence on SS than PSS (.23), which is related to society. However, despite the fact that SLSA is not about the attitude toward the organization, but about studying abroad, it has been shown that the influence of POS (.23) is greater than that of PSS (.18). This means that the support of the school(organization) is more important than ever for the SS and SLSA of international students. In addition, the SS (.36) was found to have more influence on CC than SLSA(.25). The influence of POS (.08) and PSS (.16) was also relatively low. These results mean that students who are satisfied with school can be more confident and committed to their future careers [24,25]. Furthermore, through the mediating effect, it can be seen that the process of improving CC by raising SS through POS is the most effective.
These findings explain what elements are needed to improve the performance of international students in a global environment from a practical point of view. Since, POS can improve the SS and SLSA of international students, schools should try to actively support them [26]. In addition, knowing that school satisfaction is an essential element for the success of studying abroad, the university has to find ways to increase school satisfaction [27]. In the academic domain, these results explain whether the concepts of organization and social support have a discriminatory impact on schools (organizations) and life (societies). The differential impact of school and life satisfaction on career commitment has also been demonstrated. Hence, similar attempts will be made in future research by finding different influences of the variables that deal with these different objects.

Limitations and suggestions for future research
First, in this study, CC was measured at the same time as other variables. In the future, it will be necessary to look at how successful students are in their careers after returning to theirhome country. Second, this study described the process of perceived support affecting satisfaction and CC. This is the result of not considering various situational factors. Future research will also require the verification of the moderating effects of diverse variables such as the students' values and personalities. Third, if the SS and SLSA are improved, more detailed studies need to be conducted to see if other variables such as grades are affected as well as CC. Finally, this study was conducted on Chinese students studying abroad in Korea. These participants will be influenced by their own cultures. Therefore, future studies should have students from more diverse cultures.
