What is CRM(Customer Relationship Management) means that planning, executing, and re-accessing the marketing strategy based on the customer character by analyzing the material related to customers. That is CRM is a strategy of customer service on the base of data. In the case of the telecommunications and a newspaper, there are restricted application of CRM, because they are provided services by paying a given amount of money within a given period of time. This paper develops CRM model(chum prediction model) that can apply to a newspaper. For model-building, real data were used which were collected from one of the major a newspaper company in Korea. Also, this paper verifies the efficient result.

Formaldehyde is important because of its irritant and toxic properties, mutagenicity and carcinogenicity, In this study, liquid chromatography/mass spectrometry (LC/MS) was used for the analysis of formaldehyde after derivatization with 2,4-dinitrophenylhydrazine (DNPH) cartridge. Analytical parameters such as linearity, repeatability and minimum detection limit were evaluated. The linearity (r²) was 0.9999 when analyte concentration ranges from 50 to 400 ㎍/L. The relative standard deviation (%RSD) was 0.83% for the concentration of 400 ㎍/L, and the minimum detection limit (MDL) was 0.27 ppbv. We investigated the distribution of formaldehyde concentrations based on a total of 96 samples(industrial area : 32, complex boundary line : 32, affected (residential) area : 32) measured at the Shi-Hwa industrial complex from April to October 2006. By the statistical analysis of these measurement data, the average level of formaldehyde from industrial area, complex boundary line, and affected area was 2.7, 2.1, and 2.2 ppb during the daytime (10:00~16:00), and 1.4, 1.1, and 1.6 ppb during the nighttime (19:30~23:00), respectively. And also, we investigated the emission concentrations of formaldehyde from various emission sources of 33 individual companies located in the Shi-Hwa industrial complex from September to November 2006. The results of our study showed that the emission concentrations of formaldehyde greatly varied according to industrial and source types. The emission concentrations of formaldehyde showed in the descending oder of 11.4 ppm for insulation cable process, 2.0 ppm for sand casting process, 1.7 ppm for synthesis rubber process, and 1.3 ppm for hexamine process.

The state and its proper countermeasures of unreported industrial accidents in Gyungbuk area was investigated throughout a survey research. The goal of the study was to identify major factors that affect the number and causes of unreported accidents. Results from the survey indicated that significant number of unreported accidents exists especially in the small and medium sized industries. Types of the accidents, amount of increase in the insurance cost and level of the governmental enforcement due to the accidents were the major factors for deciding whether to report or not. These results suggested more compromising actions have to be taken by the government for revealing the present but unreported industrial accidents. A more efficient way for preventing the industrial accidents can be considered on the basis of true understanding about real industrial accident statistics.

In many manufacturing occupations, industrial workers reported foot or lower leg problems such as discomfort, pain or orthopedic deformities. This study investigated the effects of two different working conditions upon assembly worker's perception of discomfort and foot pain associated with various body parts. Twenty-three male volunteers performed work in the factory. Ergonomic intervention has been to modify the flooring in an attempt to alleviate the problems associated with constrained standing and walking work. The worker's standing conditions consisted of standing on a hard floor while wearing shoe insoles. Questions were asked regarding body discomfort and foot pain. Significant differences in body discomfort and foot pain were found when comparing the overall effects of wearing shoe insoles on a hard floor (p<.05). This investigation indicated that shoe insoles reduced body discomfort and foot pain (p<.05).

The purpose of this study was to analyze usage frequency and importance of competencies which are required to restaurant industry professionals. For this purpose, opinions of restaurant industry professionals on the competency were surveyed using questionnaires. To develop a questionnaire, a total of 27 competency variables which are required to restaurant industry professionals were drawn through literature review. Questionnaires were distributed to 300 professionals in restaurant industry with different positions using random sampling. Out of 300 questionnaires, 221 questionnaires were used for analysis. Statistical analysis was conducted using SPSS 10.0, including descriptive analysis, ANOVA and t-test. Reliability test and factor analysis were also conducted to evaluate the reliability and validity of the questionnaire. As a result, 'attitude and personality' factor was recognized as the most frequently used and the most important competency factor of restaurant industry professionals. Therefore, the competency such as 'sincerity', 'responsibility', 'sense of honesty', 'positive attitude', 'tolerance and justice', should be more emphasized in restaurant management education. The level of current usage and importance of each competency were different according to age, education level, working experience, position, number of employees, type of restaurant and type of management.

If you examine the Industrial Disaster Analysis Content that occurs every year in the small and medium enterprise, industrial disaster occurs because of manager's lack of safety and worker's unprepared safety education. Therefore effective safety education systems are needed to offer adequate knowledge and technology to the workers. On this research, to give an effective education way to decrease industrial disaster we administered to the workers who are in charge of 300 workplace in Incheon area to search actual condition of industrial disaster and to disclose a link between industrial disaster and industrial safety education. We put in effect on frequency study and examined x2 using SPSSWIN 10.0. On the research, the results shows that the industrial safety education and training are in effect regularly and the satisfaction are low. But the manager's satisfactions are high through safety education. So it shows that we need to find a way to put in effect safety education to satisfy the workers.
