The purpose of this paper is to compare technical efficiencies and productivities without and with environmental constraints, and shadow prices of $SO_x$ in Korean and Chinese industries. The technical efficiencies without and with environment in Chinese manufacturing industries are higher than those in Korean manufacturing industries for 2000-2004. Most of individual Chinese manufacturing dominate those of Korean manufacturing in levels of technical efficiency. In terms of productivity changes excluding environmental constraints, the rates of annual growth in Korean and Chinese industries show 1.13 percent and 2.73 percent respectively. But Korean industry in productivity changes considering $SO_x$ reduction shows 2.41 percent, higher rate of growth than 1.58 percent of Chinese industry. In the shadow prices of $SO_x$, the reduction of an additional unit of $SO_x$ in the Korean manufacturing needs a decrease of 1.473 unit of output, while the shadow price of $SO_x$ in Chinese manufacturing is 0.0049, close to zero. Korean manufacturing should be specialized in higher sectors of technical efficiency and productivity and be also kept efficient in pollution abatement cost.

In this paper a method for remotely-sensed assessment of eutrophication was experimented. The water samples were collected for analysis of COD (chemical oxygen demand) and nutrients concentration, and the remote sensing reflectance data at the sampling points were synchronously measured using above-water method in two cruises, which were conducted in the Pearl River Estuary in January 2003 and January 2004 respectively. Based on the in-situ data the local algorithms for estimation of concentration of nutrients (P and N) and COD were developed by Partial Least Squares (PLS) regression. The algorithms were then applied to atmospheric-corrected SeaWiFS data and the COD and nutrients concentration in Pearl River Estuary were estimated. And then the assessment of eutrophication was carried out by comparison of the estimated nutrients and COD value with the water quality standard. The results show that the whole estuary is seriously in eutrophication.

Geometry is one of the important parts of Chinese school mathematics. There is a large difference in teaching and contents (standards, curriculum) between the US and China. Many mathematics educators in both countries are trying to reform the instruction of geometry and have made some progress. Close attention has been given to the Principles and Standards for School Mathematics (NCTM 2000), in which we have found many good ideas. In this paper, we introduce new developments of school geometry in China and have made some comparisons between the US and China. The new technology is becoming popular step by step in Chinese high schools. We believe we should learn from each other and exchange the ideas. In doing this mathematics teaching will be improved.

We used the quantitative method to compare with Chinese junior middle school students' mathematics belief systems in Chaoxian and Han nationalities, and their correlations within its own group. By comparison, the results revealed that all students in Han and Chaoxian nationalities hold multiple beliefs, and their belief systems are not stable. In addition, there were some differences and similarities between their belief systems in two nationalities, and significant correlations were founded.

This study reviews critical literatures regarding Asian cinema, focusing on studies of Japanese cinema, to show that Western scholarship on non-Western national cinemas have been divided into two approaches: traditionalism and modernism. It argues that such a division is not merely a critical tendency but indicative of the fact that a national cinema is an internally divided construct. To support the point, this study examines Chinese film studies conducted by Chinese film critics and the history of South Korean cinema during the 1970s and 80s. Then, it proposes the hegemony model to theorize the inner structure of national cinema. It finally suggests the possibility of comparative film study that the national cinema thesis may activate.

If 《Bailuyuan》 is a piece that reflects the trend of changing Chinese contemporary literature after the 1990 reform and the opening up of socialism, 《Taebaek Mountain》 is a literary masterpiece that shows the peak of the people and coincided with subject controversy in the 1980s. These two pieces of literature were based on a common experience swayed by the encroachment of Japanese imperialism, and they became best sellers in Korean and Chinese literary circles in the 1980s and 1990s. Based on their similarities, this paper focused on and took a closer look at character modeling in the two texts. In these books, the investigators also discuss how the main characters of Bailuyuan and Taebaek Mountain are portrayed, and how this portrayal strategically works to realize the theme of the text as well as the literary significance, value, and expected effects of the comparison between these two pieces of literary work.

The present study aims to investigates the effects of the physical sound clarity (D50, STI) on the subjective speech intelligibility of the both Korean and Chinese languages which can be caused by increase of the sound absorption in classroom. In order to this, sound measurements were undertaken at a classroom with and without absorption materials. Also, speech intelligibility tests were conducted by Korean and Chinese students using their native languages. As the results, it was found that both sound clarity and speech intelligibility were improved with increasing sound absorption. Also, it was revealed that Chinese speech intelligibility was more improved than Korean with same impose of sound absorption. It was considered by the difference of phonetic characteristics of two languages. Analysing correlation of physical sound clarity and subjective speech intelligibility, it was shown that D50 is highly correlated with Korean (0.696) and Chinese (0.707) respectively. Also, STI was highly correlated with Korean (0.651) and Chinese (0.665). Thus, it can be concluded that D50 and STI have significant correlations with the speech intelligibility.

Objectives : To address suitable method for designing clinical trial intervening Traditional Korean Herbal Medicine on General anxiety disorder through the recent clinical research in Chinese Herbal Medicine. Methods : Randomized, controlled trials(RCTs) of treatment of general anxiety disorder intervening herbal medicine were searched through CNKI databases. We examined several item of studies and evaluated using Jadad scale. We searched articles in CNKI with the key word "General anxiety disorder or 廣範性焦慮症", among them we selected the clinical trial studies related with herbal medicine except for case reports, studies of acupuncture therapy or west medicines. Results : 11 RCT studies of herbal medicine met inclusion criteria. The Studies used CCMD-3, HAMA as inclusion tool and mainly HAMA as a evaluation tool. Studies were progressed for 2-8 weeks, mostly used various positive control. Experiment medicine were mainly 理氣劑, 安神劑. In most studies, experiment group made similar or higher efficacy in comparison with control group. Mean Jadad score of studies was $1.3{\pm}0.67$, and only one study was double-blinded among 11 studies. Conclusions : RCT studies on general anxiety disorder of chinese herbal medicine tend to focus on investigating effect of herbal medicine through setting positive control group with CCMD-3 and HAMA. But, most studies had low quality of trial, for lack of pattern identification, evaluation and inclusion tool of chinese medicine. Clinical trials of general anxiety disorder should provide good quality by randomization, double-blinding, and multi-site trial.

The purpose of this study was to compare the visual sensibility of red shirts in university students of two countries, Korea and China in order to suggest the color planning for shirts. Seven tonal red shirts' visual sensibility and preferences were evaluated by the students of Korea and from China in the sense of sight. Evaluated data were analyzed by using frequency analysis, average, factor analysis and t-test. The visual sensibility of red shirts was classified into three factors: sporty, romantic and classic. Those factors of visual sensibility showed a significant difference according to nationality and gender. The Chinese students had a more sporty feel to the strong tone, and a more classic feel to the dark tone than the Korean students. The deep tone red shirts was reputed to be more romantic by the Korean students, but the light tone and the pale tone were considered more romantic by the Chinese students. Meanwhile, the effects of nationality and gender on seven tone of preferences for red shirts was significantly differed.

Natural selection is the core idea of evolution that pre-service biology teachers need to understand to solve diverse biological problem. This study aims to investigate the level of Korean pre-service biology teachers' understanding of natural selection by comparing their knowledge with their Chinese, American, and German biology major undergraduate counterparts. In particular, this study focuses on two conceptual components of natural selection (i.e., ecology and genetics). This study used a total 1226 pre-service biology teachers and biology majors' data. The instrument measuring the understanding of natural selection concepts was Conceptual Inventory of Natural Selection, which consists of ten ecology concept items and ten genetics concept items. The Rasch model analysis, multivariate analysis of variance, and univariate analysis of variance were used for the statistical tests. The result reveals that the level of Korean pre-service biology teachers' understanding of natural selection were similar with Chinese undergraduates' understanding and significantly lower than American and German undergraduates.' In the first year student data, the level of genetics concept of Korean pre-service biology teachers were significantly lower than Chinese and German students. In the fourth year student data, the level of ecology concept of Korean pre-service biology teachers were significantly lower than American and German students. Based on these results, the ecology concept education and balanced natural selection concept education are discussed.
