The long-term perception investigation of environment is needed for the persistence of each country's policy on climate change, which is greatly influenced by external factors. Long term data on perception and attitudes of people's thought can be a big data point for climate change and consistent policies can be implemented with the need for public demand. Information on the perception of the general public regarding the environment should be carried out as a basis for the national environmental policy.

The concept of style provides a useful structure in history of Art. In aspect of formative art, dress and art work are alike, so style is a useful concept in the historical methodology on dress. The main purpose of this study was to apply the art criticism to the historical methodology on dress. For this purpose, documentary studies about style as a tool of historical research were proceeded. The results were as follows : 1. The concept of style consists of the external form and the internal meaning as double roots. Therefore, it's indispensable that the two asp-ects of style, form and meaning, must to be harmonized to describe the historical phenomena in dress. 2. The change pattern of style in dress is not always predeterminate and regular according to the cyclical theory. From the alternative point of view, the change pattern of style could be to describe the continuous theory proposed by kroeber, Brodsky. The whole change of style is considered "liked solution" by this theory.is theory.

This investigation was carried out in Liaoning, Shandong, and Shaanxi where classified most of their geological organizations into profit organizations, which means they must implement enterprise-oriented reform immediately. The valid 311 questionnaires were collected and used to verify the serial mediating model by AMOS 23.0. Results verified the crucial mediating effects of structural and psychological empowerment between external-focused organizational culture and openness for change. Adhocracy culture positively affects employees' openness for change through three indirect paths, including one mediator and two mediators. Market culture impacts individuals' openness for change through two indirect paths, one is through structural empowerment and another one is through two mediators. The findings provide managers in geological organizations with an empowering management practice model which could promote geological industry reform effectively.

This study was conducted to examine the growth change in external nose according to age which plays an important role in determining the facial profile, by analysing the biennial serial lateral cephalograms of 20 males and 20 females of mean 8.5 years old to 16.5 years old who have a normal occlusion. The results of this study were summarized as follows. $\cdot$ Both mean and standard deviation were obtained according to each item, sex and age for the male and female. $\cdot$ Nose heights of the male and female increased with increase in their age. The upper to lower nose height ratio somewhat decreased for both male and female with increase of age. The mean ratio was 3.69 : 1 for the male, respectively, and 3.83 : 1 for the female during this study．$\cdot$ The nose depth indicated the most significant increase of all items according to the increase of age, while the sagittal depth inicated higher value for the female than that of the male in the most age groups. $\cdot$ The nose inclination did not show a remarkable change during this study. $\cdot$ The proportions of growth completed at the earliest age showed the highest percentage for sagittal depth(male : $87.14\%$ & female : $91.29\%$). Also, the male indicated the lowest percentage in lower nose height $(73.04\%)$, while the female did the lowest in nose depth$(79.09\%)$. $\cdot$ There was shown the variable of the greatest correlation between the upper nose inclination and nose depth. $\cdot$ From this study, the whole external nasal growth was occurred downward and forward which was more frequent for forward growth than vertical growth.

Absorption pattern of potassium, calcium, phosphate and nitrate ions, and the pH change during ion-absorption at pH 3.0-11.0 by Oryza sativa L. were studied to investigate indirectly the evidence of H^+-efflux by ATPase. The rice seedlings which were grown either in $L^{\circ} -dark or in L^+-sunlight$, were used both in each ion-absorption to compare with one another. The uptake rate of these ions appeared to favor more in $L^+than in L^{\circ}$, over all range in pH, nearly with the same pattern. The absorption of potassium resulted in bell shape and that of calcium increased linearly to the alkali range. The shape of phosphate-absorption showed nearly the t-distribution curve with high value in acid range and the uptake of nitrate resulted in the dual peaks, but higher in acid range. The pH of the external solution changed from the range of 3.5-11.0 to 3.5-7.0 after lhr-absorptioin, and further acidified after 3hr-absorption. It is suggested that the pH change of the external solution be affected by $ H^+-efflux$ which may be caused by the ATP-hydrolysis.

After Chinese reforms and market opening, China actively started working on ways to attach importance to the ocean and it's maritime strategy has been developed and carried out by external and internal factors. We can take two things as external factors attributed to China's marine strategy. The first one is maritime environment change in the East Asian region and the second one is the strategic importance of Taiwanese Straits and the South China Sea. And we can take about national strategy, security strategy, and change of foreign policy as internal factors. China recognizes the ocean as a major step to achieve a goal of national development. The main goal of China's marine strategy in the 21st century is to secure marine transportation and marine resources and to make peaceful maritime environment in the ocean to keep up with their economic development by opening itself to the world. China has strengthened their defense abilities to act against threat of national security by modernizing sea forces and increased national power by building up the marine power. It is expected that China will continue to seek more aggressive maritime strategy on matters of national security as well as pour heir efforts into making economic development and obtaining energy resources. This will also be one factor making new dynamics between countries in and around the East Asian region.

Spontaneous bilateral cerebellar infarction in the territory of the superior cerebellar arteries is extremely rare. Occasionally there have been reports of bilateral cerebellar infarction due to vertebrobasilar atherosclerotic occlusion or stenosis, whereas no report of bilateral cerebellar infarction due to complicated hemodynamic changes. In this report, we present a patient with bilateral cerebral infarctions related to stenoses of bilateral internal carotid arteries, in whom vertebrobasilar system was supplied by multiple collaterals from both posterior communicating arteries and right external carotid artery. We performed stent-angioplasty of bilateral internal cerebral arterial stenosis, and then acute infarction developed on bilateral superior cerebellar artery territories. The authors assumed that the infarction occurred due to hemodynamic change between internal carotid artery and external carotid artery after stent-angioplasty for stenosis of right internal carotid artery.

The object of this study was invest, igat, ing the failure phenomenon in the contact zone of rcpnired concrete structures due to the external climate change(hygral transient condition). This study was carrie out by calculating the non-stationary moisture and stress distribution in the repaired concrete structures with the cement mortar. In this analysis, main variables were the overlay thickness (Do=0.5-2.5cm). and the pre-wetting time(tc= l-5days). and the cxtcrnal 1.~1ative humidity(Ho=50-80%). The results show that the minimum overlay thickness and the minimum pre-wetting time are necessary to k e ~ p compressive stresses in the contact zone for a relative humidity.

This paper introduces an emotional behavior decision model based on linear system for intelligent service robots. An emotional model should make different behavior decisions according to the purpose of the robots. We propose an emotional behavior decision model which can change the character of intelligent service robots and make different behavior decisions although the situation and environment remain the same. We defined each emotional element such as reactive dynamics, internal dynamics, emotional dynamics, and behavior dynamics by state dynamic equations. The proposed system model is a linear dynamic system. If you want to add one external stimulus or behavior, you need to add just one dimensional vector to the matrix of external stimulus or behavior dynamics. The case of removing is same. The change of reactive dynamics, internal dynamics, emotional dynamics, and behavior dynamics also follows the same procedure. We implemented a cyber robot and an emotional head robot using 3D character for verifying the performance of the proposed emotional behavior decision model.

The movie costumes may serve to change individuals'ego identity, shift a gender identity to another one and make multiple and plural gender identities shared. The unique identities shown in movies can influence the audience to the extent that they will imitate characters's costumes or appearance in their real life, replacing their inner, unrealizable and private fantasy with real one. The purpose of this study is to review the movies produced in 1930's and thereafter by categorizing the socio-cultural gender concepts into masculinity and feminity. Masculinity and Feminity are not attributions fixed by some physical characteristics, but it tends to be changed or expended by some social factors over time. In short, it may be a flexible, plural, individual and self-introspecive attribute. Movies present diverse types of masculinity and feminity, and in particular, the movie costumes specify them. In other words, the costumes may be model means expressing the masculinity and feminity, and the gender identities shown in the movies tend to be imitated, re-created or assumed by the audience. All in all, the movie costumes serve to take on the confrontation of masculinity and feminity between inner, unrealizable and private fantasy and external reality and thereby, expand it from internal to external issue and thus, change or reform masculinity and feminity.
