Mycobacterium avium paratuberculosis (MAP), the cause of Johne's disease in animals, may be a causative agent of Crohn's disease (CD) in humans, but the evidence supporting this claim is controversial. Milk, meat, and water could be potential sources of MAP transmission to humans. Thus, if the link between MAP and Crohn's disease is substantiated, the fact that MAP has been detected in retail foods could be a public health concern. The purpose of the present study was to review the link between MAP and CD, the prevalence of MAP in foods, heat inactivation, control of MAP during food processing, and detection methods for MAP. Although MAP positive rates in retail milk in nine countries ranged from 0 to 2.9% by the culture method and from 4.5 to 15.5% by PCR, high temperature short time pasteurization can effectively control MAP. The effectiveness of pasteurization to inactivate MAP depends on the initial concentration of the MAP in raw milk. Development of highly sensitive and specific rapid detection methods for MAP may enhance investigation into the relationship between MAP and CD, the prevention of the spread of MAP, and problem-solving related to food safety. Collaboration and efforts by government agencies, the dairy industry, farmers, veterinarians, and scientists will be required to reduce and prevent MAP in food.

This paper serves to analyze discourses on concubine at the beginning of the modernization era or during the enlightenment period of Korea. For this analysis, the estimated time frame of the enlightenment period will be from 1860 through the time when Korea was annexed into Japan, which was in 1910. The discourses appeared in newspapers and Shinsoseol which are the text of this study have been analyzed with the qualitative research technique. The major conclusions that are derived from the study are as follows: First, intellectuals during enlightenment period of Korea, criticizing concubinage, tired to establish the monogamous relationship and they argued that it should be the prior condition for Korea to enter into the civilized society. Second, the concubinage was criticized in the point of the newly established view. The criticism was on double sex ethics, applying different ethical standards to men and women and the prohibition of wifes jealousy of concubine. Third, intellectuals during enlightenment period of Korea were tried to do away with concubinage by enforcing the discrimination between wife and concubine. But the efforts resulted in making concubinage personal problems. Also consciousness based confucian ethics including female virtues was forced to be followed in ordinary affairs while concubinage was criticized in the point of the view of western ethics based consciousness. The huge differences between two ethics consciousness resulted in serious conflicts in family.

Korean overseas construction has been on the rise, and exceeded the 2011 goal of $50 billion by securing $59.1 billion in orders. However, these orders were heavily concentrated in the Middle East (50%) and plant construction contracts (75%). This study suggests that, to maintain growth in foreign markets, Korea construction companies should enter into the high value-added investment development business and aggressively seek ways to diversify their regions of activity and construction types. To secure the entry of Korean construction companies into lucrative markets and better understand the competitive factors facing Korean construction concerns, a survey of the literature and focus group discussions targeting relevant experts were carried out. From those efforts, a list of 44 competitive factors crucial to entering and competing in the international investment development business was developed. Survey responses were analyzed by applying IPA. The results revealed that while Korean concerns compete well in engineering/technical capabilities, maintaining a cooperative relationship with contractors, and warranty/after sales service capabilities, their ability to obtain business information on the target country, to form private/public cooperative systems, and to build international human networks require immediate improvement.

The purpose of this study was to review the contents of the family ethics of Cho-Seon Dynasty in $\boxdr$Sa So Jeol$\boxul$written by Deok Moo Lee in 1775. The major findings on the family ethics of Cho-Seon Dynasty can be summarized as follows: 1) The marital relationship must keep to be equal, although they have different characters in the personality and different roles in the family. And husband/wife has to respect each other, to try to do for the marital harmony, and to treat nicely to his/her spouse. 2) In the parents-children relationships, children shoed respect and support their parents sincerely while parents’lifetime and perform an ancestral sacrifice wholeheartedly after parents’death. And parents haute the right and duty to educate their children. They have to teach their son to attend to his studies with diligence and teach their daughter to make efforts for the family and kin relationships. If parents or children are in fault, children shoed request to rethink the parents’fault to their parents earnestly and parents must also admonish their children with love. 3) In the sibling relationships, they have to show the fraternity each other. And the younger has to respect especially to elder brother.

Aviation industry, which is highly dependent on human resources, emphasizes airline's human resources management and performance check because quality of services provided to customers is closely related to airline's employees. Because roles of cabin crews take a significant portion of services provided to customers, airlines and cabin crews represent an inseparable relationship. Attitudes of cabin crews who plays the role of facing and dealing with customers directly in the process of providing flight related services are an essential factor that determines an image of an airline and actually have significant impact on the performance as well. By increasing performance satisfaction of cabin crews, organizational loyalty can be strengthened and such successful human resources management could have a positive effect on increasing customer satisfaction as well as revenues. From corporate's perspective, performance satisfaction of an employee is a crucial factor that decides the quality of service provided to customers that supports employee retention as well as client retention. This can eventually lead to organization loyalty that can positively affect overall work performance. Thus if corporates put efforts in and invests to improve and develop favorable attitudes and service quality within employees, performance satisfaction and organizational goals will be more effectively achieved.

Because the difference between products and services are getting less and less, service and manufacturing companies' efforts are increasingly focused on utilizing services to satisfy customers' needs under today's competitive market environment. The value of services depends on service reliability that is identified by satisfaction derived from the relationship between customer needs and service providers. In this paper, we extend concepts from the fault tree analysis for reliability analysis of tangible systems to services. We use an event-based process model to facilitate service design and represent the relationships between functions and failures in a service. The objective of this research is to propose a method for evaluating service reliability based on service processes using service blueprint and FTA. We can identify the failure mode of service in a service delivery process with a service blueprint. The fuzzy membership function is used to characterize the probability of failure based on linguistic terms. FTA is employed to estimate the reliability of service delivery processes with risk factors that are represented as potential failure causes. To demonstrate implementation of the proposed method, we use a case study involving a typical automotive service operation.

The IS project is getting more and more complicated and large-scaled. Many researchers and practitioners are interested in the IS development methodologies, automated tools and techniques, TQM to decrease project failure, and to increase IS performance. But, in spite of such various efforts, the latest Standish Group's research indicates that the project scale is bulkier than $1{\sim}2$ year ago and IS development project's batting average falls from 34% to 28% at the same time, proceeded project is increased, and project discharged arrives to $15%{\sim}18%$. According to a research, success possibility increased by 37% after a year of PMO introduction, and increased sharply by 62% after 2 years and by 65% after S years. This research has a goal to survey how the PMO function and operation type affect the IS project performance in the financial industry. I determine nine independent variables and three dependent variables from previous researches. The results of this study are that the four core functions of PMO have relationship with project performance. But, technical support function does not relate with organization performance. Among the four core PMO operation types, three types have an effect on the IS project performance except the perfectionist type.

This study is focused on how to effectively support Busan regional footwear companies in partnership with parent company, in particular how to lead a mutual supplementary relationship with the minor firms while improving the efficiency in strategic outsourcing. Recently, The Korean Footwear Industries and companies are making a lot of efforts to enhance the structure of high expenditure and low efficiency as a means of recovering their competitiveness. As a domestic companies have a tendency to almost all the tasks on bloc, it is true that their competitiveness is on the rapid decline for they prefer self-reliance on the premise that all the production should be dealt with for themselves. It is strategic outsourcing that is taken into account as a strategic vehicle for converting such self-reliance into the system of low expenditure and high efficiency. This study also conducted questionnaire researches, designed to find out the difference between the parent company and minor firms in the recognition and contentment on the purchasing and supplying activities. The result of the questionnaire researches went through further analysis and study to give a reasonable alternatives.

Cancer is a complex multifaceted illness that affects different patients in discrete ways. For a number of cancers the use of chemotherapy has become standard practice. Chemotherapy is a use of cytostatic drugs to cure cancer. Cytostatic agents not only affect cancer cells but also affect the growth of normal cells; leading to side effects. Because of this, radiotherapy gained importance in treating cancer. Slaughtering of cancerous cells by radiotherapy depends on the radiosensitivity of the tumor cells. Efforts to improve the therapeutic ratio have resulted in the development of compounds that increase the radiosensitivity of tumor cells or protect the normal cells from the effects of radiation. Amifostine is the only chemical radioprotector approved by the US Food and Drug Administration (FDA), but due to its side effect and toxicity, use of this compound was also failed. Hence the use of herbal radioprotectors bearing pharmacological properties is concentrated due to their low toxicity and efficacy. Notably, in silico methods can expedite drug discovery process, to lessen the compounds with unfavorable pharmacological properties at an early stage of drug development. Hence a detailed perspective of these properties, in accordance with their prediction and measurement, are pivotal for a successful identification of radioprotectors by drug discovery process.

It is attempted to estimate excitation force of a linear vibratory system using measured vibration responses. The excitation force is estimated from the relationship between the vibration response and system characteristic matrices which are extracted from both the mathematical model of the system and actual response in contrast to the usual approach of inverting the frequency response matrices. This extraction scheme is based on the fact that the vibration response can be expressed in term of linear combination of frequency domain modal vectors defined as mutually orthonormal basis vectors in frequency domain. The extracted frequency domain basis vectors are very stable in computational manipulation. It is found that the estimated excitation force is in good agreement with actually measured force except at the natural frequencies the structure, which is the common feature still to be overcome by the research efforts in this area. From the results of this paper, this disagreement is considered to come from the discrepancy between the model and actual value of the mass, damping and stiffness of the structure.
