  • Purpose : First, this study is to look into difference between dental hygienists' demographic characteristics and their job satisfaction by examining their demographic characteristics and job satisfaction. Second, this study is to analyze demographic factors of dental hygienists which influence their job satisfaction. Method : This study was made through mail survey with questionnaires for dental hygienists who are personally performing dental hygienist duties at dental clinics in Seoul between June 19 and July 24, 2008 by looking into factors influencing dental hygienists' job satisfaction in order to provide them as background data to enhance their job satisfaction. Total 180 questionnaires were distributed, and among these, 156 questionnaires excluding 24 questions of incomplete responses were statistically analyzed with SPSS 12.0. Result : First, the total mean of dental hygienists' job satisfaction was found to be 2.99 points out of 5 points, and that of their autonomy to be the highest as 3.26, and that of their salary to be the lowest as 2.55. Second, for relation between general characteristics and job satisfaction of dental hygienists, significant difference was found just in job experience(p<0.05), current position(p<0.05), average salary(p<0.001), and the expected period of engagement in dental hygienist duties(p<0.01). Third, descriptive power on demographic characteristics, which were used as an independent variable influencing their job satisfaction, was found to be 17.7%, and among the said factors, average salary had a statistically significant effect on their job satisfaction(p<0.01). Conclusion : The point of salary factor was lowest among 5 factors composing dental hygienists' job satisfaction, and as a result of multiple regression analysis, a factor influencing job satisfaction was average salary. Therefore salary system is required to be improved in order to increase their job satisfaction, and further studies on factors influencing their job satisfaction are also required to be made.

  • The safety factor has been used widely and uniquely at present to check the safety of the structure . However, probability of failure would be logically attempted to check the reliability of the structure in future Coulomb's theory or Rankine's theory has been applied in practice to retaining earth structure in spite of the fact that the lateral earth pressure, which is the primary factor in the determination of wall structure, depends on the modes of wall movement . This study is concentrated on the two modes of , wall movement (active case rotation about bottom(AB) , active case rotation about top(AT)) of the overturning'failure of vertical wall with horizontal sand backfill . The static active earth pressure is determined by applying each of Coulomb's theory, Dubrova's redistribution theory and Chang's method The earthquake active earth pressure is determined by adding Seed and Whitman's earthquake pressure to the static earth pressure , On the condition that design variables are fixed with each of the above earth pressure, reliability is analyzed using the recently developed method of AFOSM (Advanced First Order Second Moment)

  • Occupational Stress is defined the stress which occurs in the workplace or organization. In Korean workers, the rate of occupational stress was 87.8% which was the highest level among OECD countries(average 80.0%). The purpose of this study was to examine the empirical verification of the Korean Occupational Stress Scale(KOSS) in physical therapists. For this purpose, the subject of this study was set up physical therapists who were working at Gyeonggi province and collected from 388 persons by using purposive sampling. The collected data was conducted explanatory factor analysis and confirmatory factor analysis in order to ascertain factor structure and practical verification of KOSS. Major results were as following: first, the reliability of KOSS was 0.83, and it means that a measure of internal consistency is high. Second, the KOSS result of physical therapists was composed 7 subscales(job demand, insufficient job control, job insecurity, interpersonal conflict, occupational system and lack of reward, organizational climate) and that is more appropriate measurement scale than the original one by using explanatory/confirmatory factor analysis. This study could be contributed as a tool for evaluation and outcome of the basic information of related occupational stress in physical therapists.

  • This study was intended to identify the constructing factors and the evaluative dimensions of clothing images. A questionnaire consisted of 110 words expressing clothing images was developed, and eight clothing photographs were selected as stimuli. 298 female subjects aged between 22 to 37 responsed to the 110 words for two photographs during September in 1991. After survey, 110 words were reduced to 62 words based on their independence, then factor analysis was conducted. As a result of factor analysis,6 factors-grace, modernity, unattractive- ness, activeness, dressiness, and youthfulness were found out as constructing factors of clothing images. One additional interest was the effect of design line to the formation of clothing images. ANOVA identified that curved line designs were perceived to be more graceful, modern, dressy, and youthful, and straight line designs were perceived to be more unattractive and active. The other interest was the effect of image factors to the total evaluation. So, regression was used. Consequently, the most influential factor to the total evaluation was found out as grace, followed by unattractiveness, modernity, youthfulness and activeness in a descending order. To identify the evaluative dimensions of clothing images, nine words of unattractiveness image factor were eliminated, and multidimensional scaling analysis was employed. Here, three dimensions were judged to be appropriate to explain the result. The first dimension in the multidimensional space was the evaluation in 'mannish image versus feminine image'. The second was the evaluation in 'simple image versus decorative image'. The third was the evaluation in 'pastoral image versus urbane image'.

  • The aim of the study is to develop the Adolescent Anger Provocation Scale(AAPS) for Korean adolescents. In order to develop the scale, two research processes were conducted. First, a total of 130 items were derived from various related research. After analyzing 130 items by a research team(2 related field professors and 2 Ph.D. students), a total of 54 items reconstructed based on redundancy, cultural relevancy, and appropriateness. Second, a survey was administered among 252 Korean adolescents. After analyzing an exploratory factor analysis, 12 items of poor factor loading were deleted. Thus, seven factors and 42 items were extracted. Seven factors were as follows: (1) threat to self-esteem, (2) uncontrollable situations, (3) violation of personal property, (4) incidents associated with rejection, (5) violation of regulation or rules, (6) disrespectful treatment, (7) unfair treatment due to age. The internal consistency and convergence validity of the scale were supported. The results of confirmatory factor analysis were also reported. In addition, study limitations and recommendations of future research were discussed.

  • Purpose: In modern corporate management, the establishment of a crisis management system that minimizes damage through measures used to respond to corporate crises is no longer an option. The importance of corporate reputation and brand asset management in modern enterprise management cannot be overemphasized and negative events that might arise from a number of different causes can cause brand crises. Research design, data and methodology: More than half of the questionnaire respondents were female (252 or 53%). More than a fourth of the respondents were aged 20 (122 or 26%) and the number of married participants was 196 (41%). Of the participants, 32% (153) had graduated from college. Only 18% (87) were employees and the monthly household income was 121. In this study, we conducted factor analysis in order to extract the variables that may enhance the explanation capability of each variable. For the method of factor extraction, an Eigen value of at least 1 was used as was factor loading. An analysis was performed using the Cronbach's alpha coefficient to verify the reliability of the measurement scale. Results: First, the analysis of the impact of the social responsibility activities on brand image revealed that the social, economic, philanthropic, ethical, and environmental responsibility activities significantly affected brand image, but legal responsibility activities were not statistically significant. Second, the analysis of the impact of brand image on loyalty showed that brand image had a significant impact on loyalty. Third, the analysis of the impact of social responsibility activities on loyalty showed that they had a significant impact on loyalty. Conclusions: The pro-social enterprise image is not only a brand asset that can be shared, but also a heavy proposition followed by a corresponding social responsibility, it will have to practice transparent corporate management based on clear principles through the establishment of various systems and the implementation of a strict code of conduct within the enterprise.

  • Load Resistance Factor Design method is used increasingly in geotechnical design world widely and resistance factors for drilled shafts are suggested by AASHTO. However, these resistance factors are determined for intact rock conditions, by comparison most of bedrocks in Korea are weathered condition, so that applying the AASHTO resistance factors is not reasonable. Thus, this study suggests the proper resistance factors for design of drilled shaft in Korea. The 22 cases of pile load test data from 8 sites were chosen and reliability-based approach is used to analyze the data. Reliability analysis was performed by First Order Second Moment Method (FOSM) applying 4 bearing capacity equations. As a result, when the Factor of Safety(FOS) were selected as 3.0, the target reliability index($\beta_c$) were evaluated about 2.01~2.30. Resistance factors and load factors are determined from optimization based on above results. The resistance factors ranged between 0.48 and 0.56 and load factor for dead load and live load are evaluated approximately 1.25 and 1.75 respectively. However, when the target reliability are considered as 3.0, the resistance factors are evaluated as approximately 50% of results when the target reliability index were 2.0.

  • This study intended to investigate the concept of Clothing Involvement and Brand and to provide useful basic data for building on affective brand strategy. The purpose of this study is as follows: first, It is to measure the result of Brand Extension attitudes and Brand Extension items by clothing involvement (high involvement/low involvement). Second, It is to classify the factors of Clothing Involvement which suggested in theoretical research and to clarify correlation between clothing involvement factor and brand evaluation, brand extension attitudes. Third, It is to investigate the affect that clothing involvement, demographic variable and brand type on Brand Extension Evaluation. Subjects of this study were the adult women in Seoul, who were extracted by sampling randomly during the fall of 1995. Questionnaire was used as major method of gathering data. They were analyzed by the SAS method such as Frequency, Anova, Duncan, Correlation, multiple regression, Factor analysis. Main result of this study were as follows : 1. In brand extension attitude evaluation by high-involve group and low-involve group, quality, reputation and buying intension of brand extension attitudes showed significant difference. B brand extension attitudes and items of high-involve group was high compare to low-involve stoup. High-involve group evaluated watch, underwear, shoes and stocking of extension items highly, and there is no involvement difference of perfume, parasol, cushion. 2. In order to classify the dimension of Clothing Involvement, it was carried out factor analysis. 1 found that Clothing Involvement was composed of 4 factors, namely, interest - fashion.perceived risk symbolism. Correlation between clothing involvement and brand extension attitude was as followed; Interest factor of clothing involvement was correlated the existing brand attitude. Brand preference of the existing brand attitude was related the image of brand extension attitude, interest of advertising was the quality and the reputation-image was the buying intension. 3. For evaluation of a factor influenced on Brand Extension, it was produced multiple -regression test. Demographic variables and brand types had some influence of Clothing Involvement and Clothing Involvement had on brand extension. 27% of interest, 26% of symbolism was explained by brand types and 15% of fashion, 6% of perceived risk was explained by brand types, demographic variables. And, 10% of brand extension was explained by interest, fashion and symbolism.

  • In order to seek out methods to reduce safety accidents caused by construction machinery and equipment, this study collects data about safety accidents and draws main risk factors by construction from the data, through SNA. It aimed to suggest safety management points to be used in future construction fields, by analyzing risk index of such factors. The finding can be summarized: First, Backhoe Bucket is the risk factor for crash accidents of average workers in earth works; boring machines-maintenance is the risk factor for fall accidents of construction machinery operators in foundation works; bending machine-reinforcing rod processing is the risk factor for jamming accidents of reinforcing rod engineers in frame works; and mobile crane-hook is the risk factor for crash accidents of average workers in lifting works. Second, works can be arranged in turn, according to the risk index: earth, lifting, frame and foundation works. Risk factors can be also arranged according to the risk index: Backhoe in earth works, pile drivers in foundation works, bending machines in frame works and mobile cranes in lifting works. This study has some limits, in that it only analyzed main machinery/equipment, among various kinds of them, for earth, foundation, frame and temporary works (lifting works) and used data collected over three years. Therefore, it is necessary to conduct an analysis using big data, by collecting additional data about a lot of machinery/equipment in future construction fields.
