To investigate the blood lead concentration, their interrelation, correlation factor and influence on pregnant women and newborn, lead concentration in the maternal blood and umbilical cord blood were determined. Samples were collected from 130 mothers who were living in the Taegu City, during March, 1989. Blood lead concentration was estimated using the Atomic Absorption Spectrophotometer(IL. 551) equipped with Flameless Furnace Atomizer (IL. 665). The mean lead concentration of maternal and cord blood were $17.47{\pm}7.92{\mu}g/d{\ell}$, $15.31{\pm}7.98{\mu}g/d{\ell}$, respectively. A significant correlation was observed between the lead concentration of maternal and cord blood, r=0.663, Y=0.667X+3.646. No significant correlation was observed between previous spontaneous abortion and obstetric complication of mother and maternal blood lead concentration. Similarly, no significant correlation was observed between the sex, gestational age of neonate and cord blood lead concentration. But the birth weight of neonate had some negative correlation with cord blood lead concentration. The blood lead concentration of mother who had engaged in manufactures were higher than others and the longer working years were, the higher blood lead concentration were. Significant correlation was observed between husband's occupational exposure to lead and maternal blood lead concentration.

The purpose of this study is to investigate the effect of organizational culture on subjective well-being in organization. For this, this study surveyed organizational culture and subjective well-being those 142 workers experienced. CVM(Competing Value Model) and COMOSWB(Concise Measure of Subjective Well-Being) were used to measure them. The results were as follows: First, organizational culture had a significant influence on the subjective well-being(p<.001) in the organization and explained it as 28.4%. Only group culture had a significant positive influence on the subjective well-being(p<.001). On the other hand, hierarchical culture, developmental culture and rational culture had no significant influence on subjective well-being. Second, organizational culture had a significant positive influence on satisfaction(p<.001) and positive emotion(p<.001), but had a negative influence on negative emotion(p<.05) which are the factors of subjective well-being, and explained them as 35.3%, 26.0% and 5.1%. Only group culture had a significant positive influence on satisfaction(p<.001) and positive emotion(p<.001), but had negative influence on negative emotion(p<.01). Based on the drawn results, this study provides practical and theoretical implications and suggests further studies.

This study analyzed the features of the nodules requiring a fine needle aspiration, which were found in thyroid ultrasonography of the employee health check-up examinees. Based on the fine needle aspiration results, over 1 cm nodules or those implying malignancy on the ultrasonography were categorized into the 1st group. Whereas, regardless of the size the fine needle aspiration results implying malignancy on the ultrasonography were categorized into the 2nd group. In the 1st group, 15.8% were malignant, and in the 2nd group, 28% were malignant. The findings implying malignancy were statistically significant. However, even though the nodules were larger than 1 cm, when the nodules were not accompanied by a high risk factor and showed a spongiform structure in the ultrasonographic results, most of them were benign, and a fine needle aspiration was not required. The ultrasonographic findings are important rationales in making a decision on whether or not a fine needle aspiration is required for thyroid nodules. Currently, the fine needle aspiration for thyroid nodules is commonly performed when the size of the nodule is larger than 1 cm, even though it has a spongiform structure, to relieve the patient's anxiety. However, if ultrasonographic findings of thyroid are correctly understood in differentiating malignant from benign nodules, unnecessary fine needle aspiration can be avoided.

This study was conducted to identify the recognition for nursing competency importance, nursing competency level, and their influencing factors of nurses in the long-term care hospitals. Participants were 243 nurses who were working in the 11 long-term care hospitals. Data were collected from August 25 to September 3, 2014. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation and multiple regression by SPSS 19.0. Mean scores of the recognition for nursing competency importance and nursing competency level were $4.21{\pm}0.48$ and $3.47{\pm}0.46$ respectively. Nursing competency level was significantly lower than the recognition for nursing competency importance. The variable influencing the recognition for nursing competency importance was the position(${\beta}=.19$). The variables influencing the nursing competency level were the recognition of nursing competency importance (${\beta}=.37$), age (${\beta}=.20$), current work experience (${\beta}=.13$), health status (${\beta}=.13$). The results suggest the need of developing measurement tool and nursing competency enhancement programs which can well reflect the characteristics of nursing competency required in the long-term care hospital.

This study analyzed the effects of wage workers' job satisfaction, life satisfaction on turnover intention, and moderating effect of employment type after the global financial crisis using Korean Labor and Income Panel Study data. As a result, we found that the higher the job satisfaction is, the lower the turnover intention. However, the higher the job satisfaction and life satisfaction are, the higher the turnover intention. This is because the more satisfied with the job environment, the higher the tendency to seek better job opportunities, or the change in occupational value that favored free work. The higher the age, the higher the educational level, and the regular jobs are, the turnover intention decreased. In addition, the interaction terms of job satisfaction, job environmental satisfaction, life satisfaction, and regular employment all showed a moderating effect of employment type. However, since the results of the relationship between job satisfaction, job environmental satisfaction, life satisfaction and turnover intention, and the moderating effect may be due to limitations of measurement variables, further study is needed.

Accelerated technological advances and the convergence of information and communication technologies have led to changes of career concepts from one of lifetime employment to that of lifetime career. Given the importance of continuous career development for workers these days, systematic supports for workers' career development at the national level is necessary. Accordingly, a conceptual model of career competency mobility map (CCMM) has been proposed to support the development of workers' career competencies. The purpose of this study is to identify key issues that we should consider for real implementation by applying to each stage of the CCMM conceptual model as a case study. Based on the procedure presented in the conceptual model, the research process which includes collecting user information, conducting self-diagnosis of NCS-based job competencies, deriving necessary training competency, offering the guidance of training programs and job information were conducted. The results of the case study showed our participants' scores of competencies required further development and ranged from 1.83 to 4.52. Sequentially, a personalized information profile was offered for competency development, including training, certificates, and job information. Participants stated that the diagnosis results and profiles were meaningful and helped to explore further career development. Based on the results, implications are suggested.

The purpose of this study was to examine the work and turnover of dental hygienists in a bid to find out problems with them and feasible reform measures. The subjects in this study were 383 dental hygienists, on whom a self-administered survey was conducted in May and June, 2010. Concerning the work of the dental hygienists by the type of dental institution, the largest group placed importance on treatment cooperation as the major duty. Both of the dental clinic(54.3%) and the dental hospital employees(30.0%) faced the most difficulties in providing treatment counseling. As to the work awareness of the dental hygienists by career, the greatest group gave weight to treatment cooperation as the major duty, and the gaps in that aspect were statistically significant (p<.05). In dental clinics, working conditions (27.2%) and in dental hospitals, salary increase (37.1%) should be given top priority for improvement. The most common reasons for which dental hygienists changed theirs jobs were significantly different between dental clinics and dental hospitals: discord with supervisors (39.3%) in dental clinics and dissatisfaction with the salary (28.6%) in dental hospitals. The difference between the two results were statistically significant (p<.05). These findings indicate that independent working and improvement in working conditions of dental hygienists are urgently needed.
