As the economic environment rapidly changes, the ability to flexibly adapt has become a vital skill which is primarily attained through education and training. Subsequently, it is essential that the effects of vocational eduction and training are closely examined to see if they are fulfilling their goals; specifically, whether they bolster the chances of gaining employment. To that end, the endogenous aspects of training variables must be controlled. This study critically assesses the approaches of current literature in regards to tackling the endogeneity issue, and investigates the effects of vocational training through various econometric models. The results failed to reveal any positive effects of Korea's vocational training on employment. However, the negative effects were also not large enough to be significant. Additionally, the marginal effects were weaker for women and older age groups-which show a disparity between men and women-than for men and younger age groups, respectively. A more comprehensive and in-depth analysis will be needed of these results using recent data and detailed information about the training process.

A case-control study was conducted to investigate the relationship between blood cadmium, blood zinc and cadmium/zinc ratio and hypertension. Eighty-three hypertensive and seventy-seven normotensive study subjects matched for age and sex were selected from the workers who had no history of job-related cadmium exposure, in Ulsan city and it's vincinity, Korea. The blood cadmium in hypertensive group was $2.90{\eta}g/mL$, which was significantly higher than that of control group, $1.99{\eta}g/mL$(P<0.01). After stratifing for smoking and age variables, the relationship was still remained. The blood cadmium/zinc ratio in hypertensive group was 2.46, which was significantly higher than that of control group, 1.65(P<0.01), After stratifing for smoking and age variables, the relationship was still remained. There was no significant differance in blood zinc between hypertensive and control group. On multiple logistic regression analysis, the blood cadmium/zinc ratio is highly significant than blood cadmium. In conclusion, there is the possible relationship between blood cadmium level which has been known to be within normal limits and hypertension. But, futrher cohort studies to define the effect of cadmium on human hypertension are required.

중금속은 산업화 이후 오늘날까지 개발도상국뿐만 아니라 선진국에서도 지속적인 모니터링을 하며 관리하고 있는 환경오염물질이다. 납(Pb)과 카드뮴(Cd)은 산업화된 도시의 대기, 수질 및 토양의 모든 환경 매체에 분포하고 있는 환경오염물질이다(Lopez-Artiguez et al., 1993; Buchet et al., 1983). 특히, 환경중의 카드뮴 노출은 생물학적 반감기가 길기 때문에 특별히 더 중요한 의미를 가지는 잘 알려진 유독성의 물질이며(Buchet et al., 1983; Muller and Anke, 1994; Ikeda et al., 1989, 1995), 장기간의 직업상의 노출과 환경노출에 기인하는 독성의 영향도 최근 연구되어지고 있다(Jarup et al., 1998).

This paper attempted to verify that Investigative Enterprising(IE) axis in the Holland hexagonal model can measure the internal and external job value. This study analyzed internal and external job values of 19 subjects who participated in the 150 Job cards classification test. The results of this study are as follows: First, the study group with Holland hexagonal model centered on the Investigative Enterprising type(IE) axis and artistic type(A) and social type(S) showed internal job value and supported the hypothesis. Second, the hypothesis that the group with the hexagonal model centered on the Investigative Enterprising(IE) axis and the bias toward the realistic type(R) and the conventional type(C) would pursue external job value was rejected. This is due to the Korean cultural context that pursues psycho-cultural value in Confucian culture. There is also a Holland hexagonal model that is not exactly distributed to the left of the Investigative Enterprising(IE) axis. Third, the group of amphibolic job value based on the Investigative Enterprising(IE) axis, and the Holland hexagonal model is expressed in artisic type(A), social type(S), realistic type(R), and conventional type(C) supported some hypotheses. This paper is the first to suggest that the Investigative Enterprising(IE) axis of the Holland hexagonal model can be used to measure job value, and the Holland hexagonal model can predict job value as well as career choice. This paper is intended to expand the foundation of the Holland theories, and to provide meaningful contribution to the basis for vocational studies.

This study emphasizes the need to understand digital transformation and addresses the development process of functional mobile games with the theme of digital transformation. Through previous research, we found that existing mobile games do not reflect the changes in industries and jobs in the future. In this study, we designed and developed an educational mobile game that can help young people develop digital literacy skills and understand core skills for future changes in industrial structure and jobs due to digital transformation. It utilizes Unity 3D and combines the best features of puzzle, card, and board games. While there may be limitations in terms of expertise in developing educational content, it is important to note that we have presented content that can provide a futuristic view of careers through a game that is highly preferred by students. Considering the direct and indirect educational effects of the game, it is expected to be useful as a vocational education content in the classroom through tablet devices that have recently been distributed in schools.

The aim of this study was to learn what directions need to be reflected when establishing the next-term trial plans by analyzing the current trial plans being implemented in Korea regarding job training and employment support for immigrant women by marriage. For this purpose, the job training suggested in the Healthy Family Basic Plan and Multicultural Family Policy Basic Plan as well as in the Basic Economic Activity Stimulation Plans for Out-of-employment Women were analyzed. Based on this, job training was reconstructed into four categories: 1) education and training program; 2) human resource development; 3) employment support; and 4) delivery system. For the analysis, the policy analysis methods reported by N. Gilbert and P.Terrile were used. The results showed that the current trial plans exhibited immaturity in the Tomorrow Learning Card and Successful Employment Package as well as in the specialization process, lack of a human resource development system, and the absence of governance. Several proposals should consider these when making the next-term trial plans.

Purpose: This study aimed to determine health problems experienced by workers in special employment relationships (WSER) and identify coping strategies used when such problems occur. Methods: This qualitative study used the focus group interview method. Thirteen study participants included five home-visit tutors, five insurance salespersons, and three credit card recruiters. The interviews were conducted from November 2018 through January 2019, with each occupational group interview lasting about 2 hours. Analysis based on phenomenological research was independently performed by two researchers. Results: Most participants had common health problems involving vocal cord symptoms, and stress related to emotional labor and traffic accidents. The unique health problems included cystitis, musculoskeletal, and digestive symptoms in home-visit tutors; reduced vision and hearing in insurance salespersons; and mental distress in credit card recruiters. There was no protection system for their health coverage, and the company emphasized their self-employed status to avoid taking responsibility for them. Twelve participants did not purchase occupational accident insurance owing to both not having adequate information and economic burden concerning premium status. Conclusion: WSER experienced both physical and mental health problems. These problems were caused by their unstable employment status, and the social security system for their coverage being non-functioning.

Objectives: The prevalence of diabetes mellitus was approximately 16% in populations of over age 30 years, and deaths from diabetes mellitus became the sixth most prevalent cause of death by disease. To assess the relationship between HbA1c and heavy metal level in blood and urine, targeted residents were evaluated in a vast steel industrial complex. Methods: We selected 414 subjects for analysis after applying the following exclusion criterion: 18 persons with diabetes mellitus. They took part in a questionnaire survey and underwent blood and urinary assessments. HbA1c and lead (Pb) level were measured in blood and, cadmium (Cd), inorganic arsenic (iAs) and mercury (Hg) were evaluated in urine. Two subgroups were divided by HbA1c 6.5%. Each subgroup was divided by 10th, 20th, 30th, 40th, 50th, 60th, 70th, 80th and 90th percentile levels of biological exposure index of the heavy metals for logistic regression. Results: Odd ratios have a tendency to increase as they go from the 90th to the 10th percentile of cadmium. However, lead, arsenic and mercury did not have significant relationships with HbA1c. In correction of age, region, gender and smoking history, a higher distribution in the subgroup with cadmium above 0.8318 ㎍/g creatinine (30th percentile) was demonstrated in the subgroup with HbA1c levels above the 6.5%, with an odds ratio of 5.26 (95% C.I. ; 1.44~19.17). Conclusion: This study found a significant correlation between urinary levels of cadmium and HbA1c in correction of several factors. It is meaningful that this outcome may be used as a basis for a study to establish the acceptable limit of urinary cadmium in Korea.

E-mail marketing is the cheapest channel in target marketing. The channel works amazingly well for marketers who know how to use it. The e-mail marketers are able to integrate transactional and behavioral data to improve the targeting content of e-mail marketing campaigns. The cost in e-mail marketing is low and e-mail marketing makes no pollution. But, the e-mail response rate is lower than all the other channels. So, it is very hard for companies to increase their sales volumes, though the companies are ready to execute e-mail marketing campaigns on the side of computer systems. Marketers can send messages easily to target customers compared to other channels. But, the possibility to be read by the customers is low. Normal e-mails are continually devalued by spam mails. This study shows the influence of e-mail marketing to increase sales used by credit cards, on the basis of the real data promoted by A bank, in the Republic of Korea. The analysis on the traits of the respondent can help marketers to target customers. If additional studies on the response prediction model on the basis of traits of potential respondents are done, the targeting method to increase the effectiveness of e-mail marketing will be better structured and organized.
