A (0,1) matrix is acyclic if it does not have a permutation matrix of order 2 as a submatrix. A bipartite tournament is acyclic if and only if its adjacency matrix is acyclic. The concepts of (maximal) order of cyclicity of a matrix and a bipartite tournament are introduced and studied.

A relatively simple model of a buried structure response to a surface loading that can simulate a possible opening and closure of a gap between the soil and the structure is presented. Analysis of the response of small and medium scale buried roof slabs under surface impulsive loading shows that the model's predictions are in fairly good agreement with the experimental results. Application of the model to a study case shows the relative influence of system parameters such as, the depth of burial, the arching coefficient, and the roof thickness, on the interface pressure and on the roof displacement. This model demonstrates the effect of a gap between the structure and the soil. The relative importance of including a gap opening and closure in the analysis is examined by the application of the model to a study case. This study results show that the deeper the depth of burial, the longer the gap duration, and the shorter the duration of the initial interface impact, while the higher the soil's shear resistance, the higher the gap duration, and the shorter the initial interface impact duration.

정확한 in vitro 전사가 일어날 수 있는 진딧물의 세포추출액을 제조하였다. 전사를 직접 조절할 수 있는 단백질 인자를 규명하기 위하여 전사개시점과 그의 상류에 결합하는 DNA 결합단백질을 탐색했다. 전사개시점을 포함하는 단편 A(-194/23)에는 52kDa, 50kDa, 40kDa의 단백질들이 결합했으며 전사개시점 상류의 DNA 단편 B(-393/-263)에는 52kDa, 50kDa, 40kDa의 단백질들이 결합한 반면 DNA 단편 C(-263/-195)는 53kDa단백질만이 결합했다. 그리고 이들 DNA 결합단백질들의 DNA 결합 활성에는 양이온이 요구되었다.

Breast cancer is the most common malignancy in women in Asia and its incidence is rapidly increasing. Information on the incidence and mortality of breast cancer is essential for planning health and more studies. This study aimed to investigate the age-specific incidence and mortality of breast cancer in Asia in 2012. A total of 639,824 cases of breast cancer were recorded in Asian countries, those with the five highest standardized incidence rates being Israel, Lebanon, Armenia, Singapore, and Kazakhstan. The highest number of deaths was observed in India, China, Indonesia, Pakistan, and Japan, respectively. Tith increasing income and improving living standards in developing countries, the incidence of breast cancer increases. This may be due to longer life, higher exposure to risk factors, eating more fatty foods and obesity, and lower pregnancy rates. The variation in incidence rates of breast cancer is very pronounced in Asia (from 80.5 in Israel to 4.6 in Bhuta). A similar situation exists for mortality rates (from 1.8 in Bhutan to 25.2 in Pakistan).

The One Pass Method (OPM) previously presented for the identification of single input single output systems is used to estimate the parameters of a Decentralized Control System (DCS). The OPM is a linear and therefore a simple estimation method. All of the calculations are performed in one pass, and no initial parameter guess, iteration, or powerful search methods are required. These features are of interest especially when the parameters of multi input-output model are estimated. The benefits of the OPM are revealed by comparing its results against those of two recently published methods based on pulse testing. The comparison is performed using two databases from the literature. These databases include single and multi input-output process transfer functions and relevant disturbances. The closed loop responses of these processes are roughly captured by the previous methods, whereas the OPM gives much more accurate results. If the parameters of a DCS are estimated, the OPM yields the same results in multi or single structure implementation. This is a novel feature, which indicates that the OPM is a convenient and practice method for the parameter estimation of multivariable DCSs.

This study was conducted to research the differences in food ingredients in the ancient Israelite period in the books of Moses, including the books of Geneses through Deuteronomy, in the Old Testament written during B.C $1446{\sim}1406$. The books introduced various foods in daily life, such as seven kinds of fruits and nuts, thirteen kinds of vegetables and grains, twelve kinds of meats, six kinds of breads and cookies, five kinds of drinks, thirteen kinds of spices, and five kinds of processed foods like butter and oil. The foods were sharply distinguished between the clean (able to eat) and the unclean (unable to eat) in the aspect of food culture. For example, foods with blood were not allowed to be eaten. At that time, bread was a staple food in Israel. There were already standard recipes for baking cookies, and appliances such as frying pans and ovens to bake bread were available. Most of the recipes in the books were the same as modern recipes, especially for wine, grape juice and raisins. Also it seems there were various spices already in use at that time, as well as processed foods made from milk.

We studied the use of time-related information, with and without prediction, to support human operators performing moni-toring and control tasks in the process. Based on monitoring and control techniques used for Project Management we developed a display design for the process industries. A simulated power plant was used to test the hypothesis that availability of predictions along with information on past trends can improve the performances of the human operator handling faults. Several designs of dis-plays were tested in the experiment in which human operators had to detect and handle two types of faults(local and systems wide) in the simulated electricity generation process. Analysis of the results revealed that temporal data, with and without prediction, signifi-cantly reduced response time. Our results encourage the integration of temporal information and prediction in displays used for the control processes to enhance the capabilities of the human operators. Based on the analysis we proposed some guidelines for the de-signer of the human interface of a process control system.
