Ji Cheng's great work on garden design theory, the 'Yuanye', written in 1631 and originally published in 1634 is the first surviving treatise and most famous and comprehensive work on the suvject in the Chinese tradition. He constructed Dongdiyuan in Changzhou about 1623, Wuyuan in Yizheng in 1631, and Yingyuan in Yangzhou about 1634. But no poems and paintings written by him still exist, and none of his known gardens has survived. Therefore his design philosophy is able to be interpreted only by his work, Yuanye. This study aims at investigating the garden design theory in Yuanye. The results were summarized as follows. 1) Yuanye reflected the garden tastes of literati, and Ji Cheng endeavored to express the deas of literati painting into gardens. 2) The essence of the garden design theory is Xingzao, and Yindi, following the existing lie of the land, and Jiejing, to borrow from the scenery, are two major activities of Xingzao. 3) Ji Cheng's design theory build up on the basis of recognizing the existence of masters. 4) Yindi is the environmental and ecological planning and design method. This is the activity to reach the state of artistry through suitability. 5) Jiejing is not merely borrowing the landscape but the making use of scenery around the garden. And only the master has the skill in fitting in with the form of the land. 6) Ji Cheng pursuits the garden which will look like something naturally created though manmade. It is the goal of the Chinese traditional gardens and ideal situation. 7) Ji Cheng aims to unify the environment and landscape design dialectically into Xingzao.

This paper presents a method for solving project planning problem which the opinions of experts greatly disagree in each activity processing time. Triangular fuzzy numbers (TFNs) are used to represent activity times of experts. And we introduce a pessimistic project planning with major TFNs and an optimistic project planning with minor. TFNs, and illustrate the approach using a combination of the existing composite and the comparison methods, which is used to solve the complex project planning problem.

The purpose of this research is to analyze the educational experiences of competent engineering students and finding the reason why they invest their time and efforts engaging in school activities. Five students with high GPA, high K-CESA scores and successful employment or entrance test scores, participated in the survey and the interview. In checking their responses, their activities' records were gathered from school DB. According to the modified framework based on the personal investment theory, the interviews, survey and DB records were analyzed on the sense of self, the social cultural environment, and pattern of behaviors in schools. The competent engineering students are able to manage themselves, in maintaining a good relationship with the collegiate, and in having high self-efficiency. They also tend to put effort into their studies and participate in inbound and outbound school activities. At the last part, freshmen foundation, relationship within college, students' activity related future career, economic stability during studies are suggested for supporting students in universities.

Thid study intends to pursue behavioral-structure of production behavior through statistical models which are using in PERT and Queueing theory. We can corprehand the orders of human production behavior's characteristics by several related attributes of probablity/statistics. These attributes are poisson, Beta, exponential distributions and P.S Laplace's natural probability. Human production behavior is related and regressed to these attributes in many divisions intermediately. Progressive numerical understanding in many essential human behavior acts on the application of practical behavior standard in production word and operation.

The theme of this study is holistic healing environment of children's library and it was researched on the basis of anthroposophy theory of Rudolf Steiner. According to Steiner's theory, human being consists of body, spirit, and soul. Especially, children are sensitive ones, and through synthetic function of 12 kinds of senses, they can be holistically healed (healing of body, spirit, and soul). As the sense independently functions or it is a element that cannot be described, it needs spatial plan to support synthetic function of it. We classified the healing space's meaning of children library by motion (including art and music), reading, & landscape healing activities and analyzed spatial characteristic to support each activity.

In this paper, we summarize briefly some of the most salient features of Repkina & Zaika's theory of learning action formation levels. We concretize Repkina & Zaika's theory by comparing various points of view of Uoo, Polya, Krutetskii, and Davydov et al. In this study we are able to diagnose students' learning action formation levels in the process of mathematics problem solving. In addition we use interview method to collect various information about students' levels. As a result we suggest data related with each level of learning action formation, and characteristics of students who belong to each level of learning action formation.

This study takes over the application of survey sampling theory to activity sampling and the application of activity sampling to time standard estimation. Cluster, stratified, and multistage sampling are studied in conjunction with random and systematic sampling. Estimation procedures that will maximize the information obtained per cost expended on the study and specification of the procedure to be used to estimate the accuracy of the estimates for the adopted procedure are considered. The use of multiple regression md linear programming to estimate standard element performance time from typical job lot production data is also considered.

Chloramphenicol molecule has an asymmetric carbon, so it has conformational isomer, namely, threo and erythro form. These two forms have great difference in biological activity, that is, only threo (-) form has biological activity. Semiempirical quantum mechanical treatments are applied to these molecules to explain the difference, using the extended Huckel theory. The theoretical predictions for the preferred conformation are in good agreement with the experimental results.

Purpose: The purpose of this study was to examine factors related with the maintenance of physical activity in Korean old adults with hypertension based on the social cognitive theory. Methods: A cross-sectional survey of 300 old adults with hypertension from five public health centers in Korea was conducted using a self-reported questionnaire. Participants were designated as "maintainer" or "discontinuer" based on the reports to the Stages of Readiness to exercise Questionnaire. Results: One hundred seventeen participants (39%) were designated as maintainers. The predictors of the maintenance of physical activity were gender (OR=3.19, p=.049), education (OR=3.50, p=.049), outcome expectation (OR=1.21, p<.001), self-efficacy (OR=.22, p=.007), and physical activity planning (OR=1.19, p=.002). Conclusion: Findings from this study suggest that nursing interventions to improve the maintenance of physical activity in the hypertensive elderly should focus on increasing outcome expectation, self-efficacy, and physical activity planning strategies especially on the female elderly with lower education level.

The aim of this study is to examine the impact of board of directors' activity on the audit committee's effectiveness score among manufactured listed companies on Saudi Stock Exchange (Tadawul) for the period 2015-2017. The final sample of this study consists of 195 firm-year observations that represent manufactured companies listed on Saudi Stock Exchange (Tadawul) for the years 2015-2017. The data of this study in terms of board of directors' meetings, audit committee size and meetings, firm leverage, firm performance, and firm age were hand-collected from the annual reports of the considered companies. The Pooled OLS regression's result indicate that audit committee's effectiveness score is influenced by the board of directors' activity. This result gives support to the agency theory prediction. This result is also consistent with the complementary function of corporate governance mechanisms in which board of directors' activity complements the function of audit committee's effectiveness score. The result of this study should be useful for manufacturing companies, Saudi Stock Exchange, auditors, and regulators which relates to the association between board of directors' activity and audit committee's effectiveness score. This study provides a new empirical evidence on the impact of board activity on the audit committee's effectiveness score in an interesting context which is Saudi Arabia.
