Purpose - As the U.S.-China trade war has become considerably worse, the Chinese government is considering applying non-tariff barriers to trade, especially local contents rule. The main purpose of this research is to check whether it is suitable for Korean investors to invest in the current Chinese capital market. Design/methodology - In order to check the stability of the recent Chinese capital market, we investigated the behavior of foreign equity investment (including Korean equity investment) in the Chinese capital market after China announced the Shanghai-Hong Kong Stock Connect (SH-HK Connect). In this paper, we researched whether international portfolio investment would or would not contribute to an increase the volatility of an emerging market's stock market (Chinese capital market) when foreign investors make investment decisions based on the objective of short-term gains by rushing into countries whose markets are booming and fleeing from countries whose markets are falling. Findings - The empirical results indicate that foreign investors show strong, negative feedback trading behavior with regard to the stock index of the Shanghai Stock Exchange (SSE), and when the performance of foreign investors in the Chinese stock market was fairly good. Also, we found evidence that the behavior of foreign investors significantly decreased volatility in SSE stock returns. Consequently, the SH-HK Connect brought on a win-win effect for both the Chinese capital market and foreign investors. Originality/value - It appeared that the Chinese capital market was very suitable for Korean investors after the China's declaration of the SH-HK Connect. However, the win-win effect was brought on by the Chinese government's aggressive capital control but the capital controls could possibly cause financial turmoil in the Chinese capital market. Therefore, Chinese reform in industrial structure and the financial sector should keep pace with suitable capital control policies.

본 연구에서는 대학생들이 물리학 실험 보고서를 작성하고 동료들과 보고서에 대한 코멘트를 주고받은 후 보고서를 어떻게 수정하였는지, 특히 동료와 코멘트를 주고받는 과정이 글 수정활동에 어떤 영향을 주었는지 살펴보았다. 보고서 초안과 수정본 간의 차이를 비교한 결과, 학생들은 글의 좁은 의미 단위를 주로 수정하였고, 글의 전체 의미 구조, 구성, 조망 같은 글의 포괄적인 의미에 대한 수정은 드물었다. 동료와 글에 대한 코멘트를 주고받는 활동이 수정행동에 어떠한 영향을 주었는지를 살펴본 결과, 글의 작은 의미 단위를 지적하는 코멘트를 받은 경우 좁은 의미 단위의 수정이 촉진되었다. 그러나 글의 포괄적인 의미 측면을 지적하는 코멘트의 경우, 학생들이 이러한 코멘트를 많이 제공하고 받았음에도 불구하고, 넓은 의미 단위의 수정으로 잘 연결되지 않았다. 즉, 학생들이 상호리뷰에서 코멘트를 제공하고 받는 경험이 이후 수정행동에 영향을 주었으나, 그 영향은 주로 좁은 의미 단위의 수정에 국한되어 있었고 포괄적인 의미 단위 차원의 문제점에 대해서는 동료의 지적을 받은 다음에도 수정이 잘 일어나지 않았을 뿐만 아니라 수정이 이루어진 경우도 효과적이지 않았다. 이러한 결과는 좋은 글의 표면적인 특징뿐만 아니라 의미 차원의 특징, 특히 글의 전체를 아우르는 넓은 의미 차원의 문제를 이해하고 해결할 수 있는 방략을 습득하는 것이 글쓰기에 중요함을 시사한다.

Under the stressed condition, a complex feedback mechanism for stress is activated to maintain homeostasis of the body and secretes several stress hormones. But these stress hormones impair synthesis and secretion of the reproductive hormones, followed by suppression of ovarian function. Cytochrome P450 1A2 (CYP1A2) plays a major role in metabolizing exogenous substances and endogenous hormones, and its expression is recently identified at not only the liver but also several organs with respect to the pancreas, lung and ovary. Although the expression of CYP1A2 can be also affected by several factors, understanding for the changed pattern of the ovarian CYP1A2 expression upon stress induction is still limited. Therefore, CYP1A2 expression in the ovaries from immobilization stress-induced rats were assessed in the present study. The stress-induced rats in the present study exhibited the physiological changes in terms of increased stress hormone level and decreased body weight gains. Under immunohistological observation, the ovarian CYP1A2 expression in both control and the stressed ovary was localized in the antral to pre-ovulatory follicles. However, its expression level was significantly (p < 0.01) higher in the stress-induced group than control group. In addition, stress-induced group presented more abundant CYP1A2-positive follicles (%) than control group. Since expression of the ovarian CYP1A2 was highly related with follicle atresia, increased expression of CYP1A2 in the stressed ovary might be associated with changes of the ovarian follicular dynamics due to stress induction. We hope that these findings have important implications in the fields of the reproductive biology.
