| Korean-Chinese is a crossborder ethnic minority group with a big population, featuristic culture and better education compared with other ethnic minority grous. Korean-Chinese university students is a special group due to their ethnic characteristics. They will definitely be confronted with adaptation to different culture when entering from their own culture to Han culture, which is a strange, but mainstream culture. This complicated process of adaptation will inevitably affact their mental health to certain extent. However, study on this issue is rare.This pater researched and analyzed the issue of cultural adaptatin, national identity and their influence on psychological health based on a lot of literature review. This study, ustilyzing and revising available meters, finally formed "Questionaire on National identity and Culture Adaptation" after trial use. The questionaire was used as a key tool for Korean students of different grades and majors in different universities in Northeast China and 555 questionaires were selected as samples.The following conclusions were drawn from the statistics and analysis:1.The culture adaptation of Korean-Chinese university student include both positive and negative adaptation, with the positive at a very high level and the negative at a low level. Therefore, the overall conclusion is that culture adaptation displays a positive aspect.2. The Korean unvierstiy students adapt well to both Korean culture and Han culture, with adaptation to Korean culture at an obviously higher leve.3. The cultural adaptation, national identity and p mental health have a complex coorelation, which includes: 3.1 Adaptation to Korean culture has direct negative impact on negative national identity, which explains the 20.3% variance of negative national identity. It also has direct positive impact on positive national identity and explains the 45.1% variance of positive national identity.3.2 Adaptation to Han culture has direct positive impact on both positive and negative national identity, but it can only explain 2.9% variance of the negative national identity and 6.9% variance of the positive respectively.3.3 Adaptation to Korean culture has direct negative impact on mental health and can explain 4.5% variance of mental health problem. The negative national identity has indirect negative impact on mental health problem.3.4 Negative national identity has direct positive impact on mental health and can explain 10.8% variance of mental health.The above conclustions indicate that the attitdue of Korean-Chinese university students to national identity is positive. However, the adaptation to Korean culture and Han culture is not well balanced, hence affact directly and indirectly their mental health. The lowering of adaptation to Korean culture couldn't be used as an approach to make balance due to the reason that the lowering of the adaptation to Korean culture will directly lead to negative national identity and mental health problem. To achieve balance requires efforts from the society to help promote the adaptation level to Han culture of the Korean ethnic university students. |
