We need the contingency cost in order to deal with the uncertainty to be accompanied inevitably at the construction and an every kind risk not to forecast in advance. And also the contingency colt needed for the change order and we need it for reduction of the delay and reduce the trouble between owner and constructor. This study, through checking and analyzing the risk factor, in the step of domestic construction, suggests optimal management reserve to specific business about the contract type and the scale. The main results of this research are summarized as follow. First, I investigated the recognition about the contingency cost, grasped the risk to be happened at the construction step and found out the frequency occurrence, through making up question to engineer are carrying out their job in the domestic construction. Second, I computed optimal contingency cost rate by the statistics investigation, and proposed an improvement plan and problem when compute a contingency cost.

The purpose of this study was to provide the guidelines for the dietary lift by analyzing and studying the dietary behavior and food preference based on the gender. In the questions whether students' food preference is similar to their parents' or not, girls answered their food preferences were similar to them (M = 3.36), but boys not (M : 2.90). In the question if the knowledge learned in school has an effect on the choice of food, girls and boys answered it did not affect them, but there was a slight difference according to the gender; boys(M = 2.54) were under less influence than girls (M = 2.88). According to the gender, there was a meaningful difference in the food preference in meat, eggs, fish and shell, beans, milk and milk products, anchovies, fruits, fats and oils, beverage, and processed food. School education had a little influence on the habits of dietary life, only 8.0%. So more practical nutrition education was needed.

In general relativity, analyzing causality is central to the study of black holes, to cosmology, and to each of the major recent mathematical theorems. By causality we refer to the general question of which points in a space-time can be joined by causal curves; relativistically which events can influence (be influenced by) a given event. Various causality conditions have been developed for space-times of the problems associated with examples of causality violations (2, 4). Causally continuous space-times were defined by Hawking and Sachs (5). Budic and Sachs (3) established causal completion. A metrizable topology on the causal completion of a causally continuous space-time was studied by Beem(1). Recently the region of space-time where causal continuity is violated was studied by Ishikawa (6) and Vyas and Akolia (8). In this paper we show characterization for reflectingness in terms of continuity of set valued functions. We investigate some properties of the region related to a causally continuous space-time where distinguishingness is violated, and characterize the chronology condition in terms of distinguishing-violated region.

In contemporary architecture, glass is being used less as a single piece for the exterior envelope, due to a variety of influences such as increased performance regulations, the market environment and technical developments. An architectural exterior wall today is usually installed as a 'ystem' wall, not as a single plane glass wall. That brings up the necessity to question the appropriateness of the materiality of an individual piece of glass for the exterior envelope in urban settings. Therefore, in many cases it is appropriate to examine materiality of glass as a system. A new examination of materiality can be carried out by analyzing the interactions between layers that constitute a system. This paper examines the experimental use of glass systems in contemporary architecture, and analyzes them to interpret the relationship between the layers of each system in order to establish the diversified materiality of glass in contemporary architecture.

This study addresses strategic issues related to the question of" how can a supply chain become more competivity\ulcorner" We examine several cases of manufacturing supply chains. Results show that each constituent firm is required to maintain different manufacturing capabilities and to play different roles by its position (up/mid/down-stream) in a chain. Furthermore, there are patterns of required capabilities by the positions in a chain. These findings imply that the "position in a chain" should be treated as one of the strategic factors when discussing the buyer-seller relationship. It is also shown that different action programs are required for building different manufacturing capabilities of individual firms in a supply chain. Additionally, we argue that some programs need to be done simultaneously, by all the members of the chain, while some need to be carried out by only a small group or an individual firm. Finally, we propose a direction for a theoretical framework for analyzing supply chain structures and strategies.ures and strategies.

Knitwears are originated earlier than textiles in human beings life. And then human beings life. And then human beings have been continuously developing as life patterns of human beings are becoming various and society is rapidly changing. Recently , changing life styles of the consumer emphasize the importance of the high quality , individuality , variety , and activity of knitwears. In this study , university women and housewives livings in Seoul have been surveyed in the cause of analyzing of the consumer's actual conditions. And eight brands of th specialized knit enterprises also have been surveyed, though it is imperfect . The purpose of this study lies in giving a help to the rational clothing habits of consumer and presenting some courses for aiming of korean knit industry. I made use of percentage and $x^2$-test for the analysis of the data and analyzed the contents of the question papers.

This study intended to provide valuable basic data for an efficient using newspaper advertising to manufactures by investising and analyzing the character of newspaper as fashion advertising and media environment, consumer's attitude of advertising subscription, a degree of recognition and concern on a newspaper advertising and a degree of like on expressive form of a newspaper advertising. A question that is drawn up by researcher base on existing records and preceding study was used as major method for understanding consumer's consciousness. The sample group is composed of female students, working women, housewives who lives in Seoul. The results of this study were as follows. 1. Manufactures should be developing Headline in subject matter to get out of plain sale advertising and event advertising. 2. Manufactures should difference to understanding Illustration that consumer prefer. Also using of photography is efficient and it is importent to use of color advertising that appeal to consumer. 3. The informative advertising is a high degree of efficiency by reason that the newspaper offers great news source and information.

N-IR spectroscopy technology is very useful. And, the technology has wide application range. In the range, we know that single beam type silica analyzer has some handicap. So we were studied Splitted beam type silica analyzer. This dissertation have been discuss about system structure, system fundamentals and performance test. At the test, we were study in the spectral interference of NH3. We know that existing system had some problem. It is structural frailties of single beam type. Therefore we were study for Splitted beam type structure. And we obtain a good result. We have $\pm$5% accuracy and 0.5 ppb level measuring range. But, we have a question. It is ppt level measuring technology by the laser beam spectroscopy.

In spite of the interest related to the entrepreneurship, the problems related to the creation of companies by the public civils servant still remain unanswered and not unanimously identified. In fact, a central question arises in this respect: "which are the factors which encourage the public civils servant to launch out in the creation of their own company?" or "how can one explain the entrepreneurial intention of the public civils servant?". For this end, and after having reviewed the principal subjacent factors of the entrepreneurial intention as well as the central assumptions of our research task, we will devote the second part to the empirical validation of the explanatory factors of the entrepreneurial intention in the specific case of the Indian public civils servant while proposing some recommendations on the matter.

High-throughput next-generation sequencing (NGS) technology produces a tremendous amount of raw sequence data. The challenges for researchers are to process the raw data, to map the sequences to genome, to discover variants that are different from the reference genome, and to prioritize/rank the variants for the question of interest. The recent development of many computational algorithms and programs has vastly improved the ability to translate sequence data into valuable information for disease gene identification. However, the NGS data analysis is complex and could be overwhelming for researchers who are not familiar with the process. Here, we outline the analysis pipeline and describe some of the most commonly used principles and tools for analyzing NGS data for disease gene identification.
