Objectives : Previous studies showed that death certification by physicians was an important predictor to improve the quality of death certificate data in South Korea. This study was conducted to examine the proportion of death certificates issued by physicians and associated factors in South Korea from 1990 to 2002. Methods : Data from 3,110,883 death certificates issued between 1990 and 2002, available to the public from the National Statistical Office of Korea, were used to calculate the proportion of death certificates issued by physicians and to examine associated factors with logistic regression analysis. Results : The overall proportion of death certificates issued by physicians increased from 44.6% in 1990 to 77.6% in 2002 (mean: 63.5%). However, the proportion was greatly influenced by the deceased's age. In 2002, more than 90% of the deceased aged 51 or less were certified by physicians. A higher proportion was found among deceased who had tertiary education (college or higher) living in more developed urban areas. Conclusion : The information regarding the cause of death for younger, well-educated deceased in urban areas of South Korea may show a higher level of accuracy. Epidemiologic research using information on causes of death may well benefit from the continually increasing proportion of death certificates issued by physicians in the future in South Korea.

This study examines factors associated with drug approvals and patent issues of the Korean pharmaceutical firms. The 22 firms were selected based on 2006 year's publicly noticed sales amount. Number of approved drugs was identified through Korea Food and Drug Administration and the information regarding the patents that each firm has issued during the year 2000~2006 was collected from the Korea Patent Office. The number of approved drugs has increased annually, especially after the introduction of substance patent system in 1987 and in 2000 again with the policy change into the separation of drug prescribing and dispensing practice. The number of initial approval of NCEs as well as the number of patents per firm decreased during the year 2000~2006. The 12 firms with larger revenue occupied more than 80% of the patents being issued. There was a positive relationship between share of prescription drugs out of approved drugs and the average number of patents issued. However, number of approved drugs did not show positive association with the number of patents issued per firm. Therefore, the study results imply that firms need to invest more in increasing number of approvals for their specific prescription drugs in order to achieve a good performance in the future.

Purpose: This study was a methodological research implemented to establish basic data for controlling the job rotation stress of nurses and effectively managing human resources by reflecting the Nurse Job Rotation Stress Scale (NJRS) developed by Huang and others into the domestic nursing environment and verifying the use of measurement tools. Methods: The study selected nurses working at four hospitals, with over 300 beds, in Seoul, Gyeongi-do, and Busan, as its research subjects and verified the content validity, construct validity, concurrent validity, and internal consistency reliability of the measurement tool. Results: The results ultimately formed eight questions from three sub-factors (3 emotional response questions, 2 daily life questions, and 3 communication questions). In terms of reliability, emotional response issued a Cronbach's of .78, daily life issued a Cronbach's of .75, and communication issued a Cronbach's of .86. Conclusion: This study is expected to be used as basic data for achieving effective human resource management by calculating the stress of clinical nurses resulting from job rotation, but the researcher believes that the measurement tools must be expanded by confirming additional job rotation stress questions which reflect the organizational culture of Korea.

This study focused on ordering factors influencing depression among late-elementary children. Subjects were 436 boys and girls enrolled in the fourth, fifth, and sixth grades of a public school. The contribution of grade, sex, 6 subtypes of stress, self-esteem, and social skills to depression was explored. The instruments were the Daily Hassles Scale, the Self-Esteem Scale, Teenage Inventory of Social Skills, and Child Depression Inventory. Results indicated that self-esteem was the most influential factor in increasing the level of depression. Next was the stress issued from friends in both males and females. There was a statistically significant difference among grades in the level of stress related to friends. The level of stress issued from parents and self-esteem among grades were marginally associated with depression. Gender differences in the level of stress from parents, friends, self-esteem, and social skills were also evident. The results were discussed in the context of the effects of subtype stress, self-esteem, and social skills on depression.

Since the first BIM development outline was issued in 2011, China has initially tried to adopt BIM in the construction industry. After the BIM guide was issued in 2017, China has officially entered the era of building informatization in the construction industry. Through the statistical data of BIM application reports in China's construction industry from 2014 to 2020, this paper concludes that China has made great progress in the popularization rate of BIM, but has little effect in the adoption in actual projects. Through the reading and analysis of relevant documents in China, 13 obstacle factors for BIM technology adoption in construction enterprises are preliminarily defined.

The purpose of this study is to grasp the degree of recognition of the ESD(Education for Sustainable Development) form Technology Home Economic teachers in high schools, to analyze contents related to the ESD within the textbooks, and to propose the improvement method of the textbooks. As a result, first, the degree of recognition on the ESD was less than about 30.1% in Technology Home Economic teachers. Second, the content and factor criterions for the ESD were developed on the basis of the previous studies. They are suitable for applying to the Vehicle Chapter in the textbooks and are including 9 contents and 7 factors, respectively. Third, the contents related to the ESD within a Technology. Home Economic textbook showed 36.1% in Technology, 33.8% in Home Economics including social and cultural(44.7%), environmental(47.1%), and economic contents(8.2%). But they in the Vehicle Chapter within the textbooks presented 69.1%, 4.8%, 26.1% in social and cultural, environmental, and economic contents, respectively. Finally, the improvement method of the new textbook for the Vehicle Chapter is to adopt issued factors including the suitable adjustment on the vehicle structure and safety as well as the supplement of environmental contents related to the ESD. In addition, it is necessary to contain the contents such as the developing process of environment-friendly vehicles, the economically sustainable consumption strategy, and the cause-and-effect relationship with the global warming in the new textbook.

We explore what factors influence the residential choice and mobility of people, and try to figure out the preferable residential district in Deagu. Household, housing characteristics, and neighborhood environments are considered as explanatory variables to predict the residential choice and the preferable residential district, and logit regression is used for the analysis. We found age, ownership, income, property, and education level as household characteristics, building age as housing characteristics, and accessibility to park and open space, public library and shopping mall as neighborhood environments are significant in determining residential choice of people whereas housing size, accessibility to elementary school, local market, cultural facility and gymnasium are not significant. These results imply people choose the residential district according to household characteristics as they did, as well as choose according to housing characteristics and neighborhood environments which are newly issued factors.

In this paper, recent research trend on heat transfer in impinging jet is reviewed. We focused on submerged jet that air issued into air or liquid issued into liquid. To control and enhance the heat transfer in single jet, researchers have performed a lot of experiments by considering the nozzle geometry, impinging surface and active method such as jet vibration, secondary injection and suction flow. The studies on multiple jet have been mainly focused on finding out the optimum condition and on investigating many different factors concerned with application condition (crossflow, rotation and geometry etc.) and combined techniques (rib turbulator, pin fin, dimple and effusion hole etc.). All most experiments showed the detailed heat transfer data by using liquid crystal method, infrared camera technique and naphthalene sublimation method. Many numerical calculations have been performed to investigate the flow and heat transfer characteristics in laminar jet region. Various turbulence models such as $k-\varepsilon-\bar{\nu^2}$, modified $k-\varepsilon-f_{\mu}$ were applied to the calculation for turbulent jet and the predicted results showed a good agreement with the experimental data. Although a lot of studies on impinging jet have performed consistently up to recently, further studies are still required to understand the flow and heat transfer characteristics more accurately, and to give a guideline for optimum impinging jet design in various applications.
