Recently, as a solution to adapt to changes in managerial environments, many companies introduce the BPM(Business Process Management) to achieve the standardization and optimization of internal/external company processes. The BPM is being highlighted compared to other managerial techniques for its diverse values such as fast responses to market changes, ensured transparency of processes, continued opportunities for improvements etc and the necessity is highlighted in the construction sector too. Therefore, this study compared the characteristics, effects of introduction and things to be improved between the BPMs introduced by various industrial sectors as an effort to establish a work process based managerial system in the construction sector and thereby drew 5 areas to be supported and compared analyzed the areas to be supported in various sectors by giving additional scores using the 3 scales method. This study is a stage to reflect the result in the construction sector where the introduction of the BPM is insufficient and by analyzing the characteristics and weak points of those BPMs introduced into various industrial sectors, this study expects effective BPM introductions and developments of construction companies.

The main objectives of the present study were to understand the knowledge and practice of breastfeeding mothers about the feeding and supplementary food and to analyze the factors related to it. The data for the present study collected from July 9 to July 31, 1984 for 302 mothers in Seoul. 1. The Knowledge of Breastfeeding Mothers about the Fee4ing and Supplementary Food (1) In the knowledge of mothers on the appropriate feeding pattern before 6 month, 69.3% of total women believed that breast-fed babies are healthier. There was a singificant difference in the type of feeding in order to education level, socio-economic state, and. mass-media exposure. (2) In the knowledge of mothers on an appropriate duration of lactation, the mean duration of breastfeeding is 8. 1 month. The duration of breastfeeding gradually decreases in order of education level, socio-economic state, mass-media exposure, and employment status. (3) In the knowledge of mothers on an appropriate time of introduction of supplementary food, the mean time of introduction of supplementary food is 4. 7 month. It is gradually decrease in order of education level, socioeconomic state, mass-media exposure, and employment state. 2. The Practice of Breastfeeding Mothers about the Feeding and Supplementary Food (1) The practice of mothers on infant-feeding before 6 month and that education level, socio-economic state and mass media exposure are the higher, the rate of breast feeding is the less. (2) The mean duration of breastfeeding is 9 month. It is 1 month longer the knowledge of mothers on an appropriate feeding pattern before 6 month. (3) The time of introduction of supplementary food is average 4.75 month. It is similar to the knowledge of mothers on an appropriate time about introduction of supplementary food. The result of this study indicate that the knowledge and practice of breast feeding is maintained comparatively high in low educated group, whereas it is noticeably decreasing among the high educated group. High educated group believed that the short duration of breastfeeding better than long, and they practiced breastfeeding so short period. And high educated group also thought early introduction of supplementary food is good for the babies health. Consequently, in this study, for the most part, elite group is found to have rather wrong opinions and practice about infant nutrition. Therefore the accurate information of infant nutrition is must be encouraged to mothers.

Free vibration of orthotropic functionally graded beams, whose material properties can vary arbitrarily along the thickness direction, is investigated based on the two-dimensional theory of elasticity. A hybrid state-space/differential quadrature method is employed along with an approximate laminate model, which allows us to obtain the semi-analytical solution easily. With the introduction of continuity conditions at each fictitious interface and boundary conditions at the top and bottom surfaces, the frequency equation for an inhomogeneous beam is derived. A completely exact solution of an FGM beam with material constants varying in exponential way through the thickness is also presented, which serves a benchmark to verify the present method. Numerical results are performed and discussed.

Nonparametric Bayesian methods have seen rapid and sustained growth over the past 25 years. We present a gentle introduction to the methods, motivating the methods through the twin perspectives of consistency and false consistency. We then step through the various constructions of the Dirichlet process, outline a number of the basic properties of this process and move on to the mixture of Dirichlet processes model, including a quick discussion of the computational methods used to fit the model. We touch on the main philosophies for nonparametric Bayesian data analysis and then reanalyze a famous data set. The reanalysis illustrates the concept of admissibility through a novel perturbation of the problem and data, showing the benefit of shrinkage estimation and the much greater benefit of nonparametric Bayesian modelling. We conclude with a too-brief survey of fancier nonparametric Bayesian methods.

There are some problems in the introduction of proof in middle school mathematics. Among the problems, one is the use of postulates and the another is the methods of proof how to connect a statement with others. The first case has been treated mainly in this note. Since proof means to state the reason logically why the statement is true on the basis of others which have already been known as true and basic properties, in order to prove logically, it is necessary to take the basic properties and the statement known already as true. But the students don't know well what are the basic properties and the statement known already as true for proving. No use of the term postulation(or axiom) cause the confusion to distinguish postulation and theorem. So they don't know which statements are accepted without proof or not accepted without proof, To solve this problems, it is necessary to use the term postulate in middle school mathematics. In middle school mathematics, we present same model of the introduction of proof which are used the postulates needed for the proof.

Safety and health education in technical high schools is especially important because the great majority of the students engage in the industrial field after graduation. But there are few reports on the state. of safety and health education in technical high schools in Korea. The aims of this study were to identify the problems of the present safety and health education in technical high schools in Korea and to propose the ways of improving health and safety education. To conduct this study, the textbooks for health and safety related courses, i.e., Introduction to Industry, Gyoryun(dril), and Physical Education, were reviewed. A questionnaire was mailed to the teachers of Introduction to Industry, Gyoryun, Physical Education, and school nurses in 188 technical high schools and the teachers of Gyoryun, Physical Education, and school nurses in 376 general high schools in November 1997. The final response rates were 42.0% for teachers of Introduction to Industry, 62.9% for teachers of Gyoryun, 47.9% for teachers of Physical Education, and 33.0% for school nurses. Also, a survey by self-administered questionnaire on the knowledge, attitude, and practice about safety and health was conducted from May through July 1998 among 44 employees graduated from technical high schools and 44 employees graduated from general high schools since 1995. The analysis of the textbooks showed that the contents of the ‘Industrial Safety and Environment’ section in Introduction to Industry were rather for safety managers than industrial workers and the contents about occupational hygiene and health were scanty. The majority of ‘Accident and Disaster’ and ‘Hazardous Substances’ section in Gyoryun overlapped with those in Introduction to Industry and several mistakes about health related descriptions were found. Some contents of Physical Education. ‘Mental Health’. ‘Emergency Care’. ‘Communicable Disease’, ‘Noncommunicable Disease’, and ‘Food Hygiene’ overlapped with those of Gyoryun. The teachers lectured safety and health related sections of textbook completely in 84.8% for Introduction to Industry, 62.1% for Gyoryun, 20.8% for Physical Education and the most frequent reason for the incomplete education was shortage of time.

Fig. 8 summarizes the present status of high yield pulp production and the directions of research on modification. A thick line indicates pulping process presently in use. As mentioned previously, one kind of modification is to introduce hydrophilic groups onto the pulp. Still unsolved is whether or not the introduction of hydrophilic groups should be restricted to lignin only. Goring (28) reported that middle lamella lignin has fewer phenolic hydroxyl groups than cell wall lignin and suggested that such a difference in the lignin may be useful in the removal of middle lamella lignin. The introduction of hydrophilic groups onto pulp may not be enough to modify high yield pulp. The removal of some portion of carbohydrate may be also necessary from the standpoint of softening of pulp fibers. There is no information at what lignin and carbohydrate, and how much should be removed. The combination with synthetic high polymers may also be important in modifying high yield pulp. Prof. C. Schuerch of the State University of New York who was a visiting professor at the University of Tokyo in 1974, mentioned that the hydrophilicity of lignin would be promoted, if phenolic hydroxyl or carboxyl groups could be introduced into the aromatic nucleus of lignin. If this were possible. this process would also mean a pulp yield of more than 100%. This idea is just one example of the expectation made possible through lignin chemistry. Instead of the introduction of hydrophilic group, the oxidative degradation of aromatic nucleus of lignin may also be useful in promoting the hydrophilicity of pulp. In this case, ozone may be an excellent chemical. However, there are a lot of problems to be solved such as homogeneity of reaction and selectivity of ozone for lignin. The above ideas are summarized in Fig. 9. There are many problems to be solved in the production of an excellent high yield pulp which is comparable to chemical pulp. The information from wood chemistry hopefully will elucidate some of the problems mentioned above.

Recently, the thoughts of Employees about the concept of workspace changes a job for a whole life time into the temporary job for an own' career development. To solve the problem, it causes the introduction of Fun Management among Domestic Corporations as the research for a fun and good workspace and the interest for the organization performance through it are increasing. However, the introduction possibility based on enough comprehension for various problems such as the strict relationship in the workspace, the rigid situation on construction site, the increase in the safe accident and the social avoidance phenomena for the employment to construction field in case that the fun management is introduced into domestic construction industry in the future is considered. Therefore, this study to propose the possibility and direction regarding the future fun management, when introduced into the domestic construction industry, by surveying and analyzing the common problems between The present state of the fun management method which is introduced and applied to other industries in advance and the performance process of the fun management which introduced and applied to the domestic construction corporations.
