Safety and health education in technical high schools is especially important because the great majority of the students engage in the industrial field after graduation. But there are few reports on the state. of safety and health education in technical high schools in Korea. The aims of this study were to identify the problems of the present safety and health education in technical high schools in Korea and to propose the ways of improving health and safety education. To conduct this study, the textbooks for health and safety related courses, i.e., Introduction to Industry, Gyoryun(dril), and Physical Education, were reviewed. A questionnaire was mailed to the teachers of Introduction to Industry, Gyoryun, Physical Education, and school nurses in 188 technical high schools and the teachers of Gyoryun, Physical Education, and school nurses in 376 general high schools in November 1997. The final response rates were 42.0% for teachers of Introduction to Industry, 62.9% for teachers of Gyoryun, 47.9% for teachers of Physical Education, and 33.0% for school nurses. Also, a survey by self-administered questionnaire on the knowledge, attitude, and practice about safety and health was conducted from May through July 1998 among 44 employees graduated from technical high schools and 44 employees graduated from general high schools since 1995. The analysis of the textbooks showed that the contents of the ‘Industrial Safety and Environment’ section in Introduction to Industry were rather for safety managers than industrial workers and the contents about occupational hygiene and health were scanty. The majority of ‘Accident and Disaster’ and ‘Hazardous Substances’ section in Gyoryun overlapped with those in Introduction to Industry and several mistakes about health related descriptions were found. Some contents of Physical Education. ‘Mental Health’. ‘Emergency Care’. ‘Communicable Disease’, ‘Noncommunicable Disease’, and ‘Food Hygiene’ overlapped with those of Gyoryun. The teachers lectured safety and health related sections of textbook completely in 84.8% for Introduction to Industry, 62.1% for Gyoryun, 20.8% for Physical Education and the most frequent reason for the incomplete education was shortage of time.

Objectives: This study examined whether the infant feeding type and duration are related to the introduction of complementary feeding, and whether the appropriate introduction of complementary feeding in infancy is related to tooth decay in toddlers. Methods: The subjects were 1,521 toddlers among 2~3 year old children in the Korea National Health and Nutrition Examination Survey from 2008 to 2015. The toddlers were divided into the appropriate group (4~6 months) and delayed group (>6 months) according to the timing of complementary feeding introduction. Results: The delayed group were 26.5% of subjects and the formula feeding period in the appropriate group and delayed group was 8.4 and 10.3 months, respectively (P=0.002). On the other hand, there was no difference in the breastfeeding period between the appropriate group and delayed group (P=0.6955). Early childhood caries was more common in the delayed group (P=0.0065). The delayed introduction of complementary feeding was associated with a risk of early childhood caries according to the logistic models (OR 1.81, 95% CI 1.27-2.57). Conclusions: The introduction of complementary feeding is associated with early childhood caries. Therefore, the importance of the proper introduction of complementary feeding in infancy should be emphasized, and public relations and education for maternal care and breastfeeding should be provided through health care institutions.

Researches on the introduction of ERP system kept on examining the critical successful factors (CSFs) that focus on factors to achieve effectively successful projects, and trying to measuring the actual effectiveness of the introduction of ERP system. However, most of the preceding researches on the effectiveness of the introduction of ERP system that was searching devoted effects has been ceased, and actually even researches on the economical results have just done the basic cognitive evaluation of result indicators by many questionnaires instead of objective measuring values, because of the difficulty of measuring the evaluation of the result. Moreover, researches on positive effects of the introduction of ERP on enterprise results and researches that failed to give advantageous effects showed different results each other. And a part of researches reported that only a part of result indicators were partially affected. In this research, we investigated Korean large enterprises or middle-sized enterprises in manufacture industry that introduces SAP R/3 and Oracle package to compare their quantitative financial results after the introduction of ERP system, in order to measure the effects of the ERP system. First, we evaluated the difference of the quantitative financial results before and after the introduction of the ERP system. Second, we evaluated the opportunities shown by the effects after the introduction of the ERP system. Third, we removed the sample of the exchange crisis (IMF) and executed the additional analysis to reflect the average increasing and decreasing rate in the industry, so that pure evaluation can be achieved. Inherent limits of precedent researches are removed and practical effects of the pure introduction of the ERP system are evaluated, so the research of this research is significant. The result of this research is as follows. Because of the introduction of ERP, the rate of turnover of inventory property has increased and sales of preparation inventory property have decreased so that more effective inventory property management has been achieved. Moreover, preparation sales of labor costs and preparation sales of the number of employees have decreased to show the effect of the reduction of labor costs. However, it could no be concluded that we could increase the profit due to the introduction of ERP system. Due to the introduction of ERP, although we concluded that the return on assets (ROA) and the additional value of one-person employee statistically showed obvious differences and increased, the return on equity failed to show obvious differences after the process of introduction of ERP.

이 연구의 목적은 공업 입문 4종 교과서의 내용 요소별 특징을 비교하여 각 교과서의 장점과 단점을 분석해보고, 그 분석된 데이터가 새로운 공업입문 교과서 개발에 활용될 수 있도록 하기 위함이었다. 궁극적으로는 현직교사는 물론 예비교사와 교육연구자들이 (ㄱ) 교과서 관련 교안 연구의 기초자료로서 사용할 수 있도록 하며, (ㄷ) 대학수학능력시험 직업탐구영역의 문제 출제와 (ㄷ) 전공과 연계성을 갖는 차기 공업입문 교과서 편찬에 있어서 좋은 시사점을 제공하는 것이었다. 주로 사용된 연구 방법은 문헌 연구로서 현행4 종의 공업입문 교과서를 비롯하여 관련 문헌을 비교 분석하는 것이었다. 연구 결과, 비교된 모든 교과서는 대체적으로 교과서 집필 안을 준수하고 있었다. 교과서의 내용 면에서는 집필 안에서 제시하고 있는 단원이 균형 있게 배분이 잘 되어 있는 교과서가 있는 반면에, 단원의 비중이 너무 편중되어 있는 교과서가 있기도 하였다. 또한 보충적 자료, 평가적 자료, 시각적 자료 등에 대한 배분에 있어서도 교과서에 따라 상당한 차이를 보이고 있었다. 교과서와 관련하여 대학수학능력시험 출제 경향은 각 교과서가 비슷한 정도의 연계성을 가지고 있으나 수험생의 입장에서는 한 가지의 교과서만으로는 대학수학능력시험을 대비하여 공부하는데 충분하지 않으므로 교사는 모든 종류의 교과서를 이해하고 학생들에게 가르치는 교과서 외의 다른 교과서 내용도 추가적으로 가르칠 필요가 있는 것으로 나타났다.

In a rapidly changing technology environment, managing and rearranging the patent portfolios is one of the main sources of competitive advantage for firms. This study analyzes the effects of patent portfolio composition on new product introduction related to resource allocation. This study also looks at the moderating role of rearranging the patent portfolios on new product introduction. Our empirical analysis of the global pharmaceutical industry shows that firms with high-value patent portfolios exhibit a tendency to launch new products, and patent portfolio diversity shows a U-shaped relationship with new product introduction. In addition, the patent portfolio rearrangement positively moderates the relationship between patent portfolio diversity and new product introduction. The results are expected to provide implications for firms' patent portfolio composition and patent portfolio rearrangement related to innovation performance such as new product introduction.

Purpose: This paper will focus on the reliability technological innovation following the emergence of industry 4.0 featured by convergence, connection and complexity. In the course of the process, the concept and application of 3R (Robustness, Redundancy, Resilience) are considered along with reliability in industry 4.0. Methods: Reliability paradigm-changes are presented to meet the purpose of keeping the desired function in Industry 4.0. And the introduction of resilience, a concept compromising reliability is to be suggested. Results: The necessity of the 3R (Robustness, Redundancy, Resilience) introduction is emphasized according to reliability paradigm-changes. Conclusion: Reliability, robustness, redundancy and resilience are not mutually exclusive. Ultimately, acquiring the resilience requires robustness, redundancy and fittable maintenance procedures.
