The purposes of this study were to reveal the backgrounds, process, and evaluation of the "Forest Survey Project(1910)" and to determine the influence of the "Comments on the Classification of Forest Land Ownership in Korea(1910)", which was based upon the results of the project, on forest policy in the early period of the General-Government of Korea. The forest survey project was conducted by two Japanese, Kiuchi and Saito, to understand the forest distribution in the Korean Peninsula by ownership and stand. However, the accuracy of the project was very low due to the lack of budget and time. Especially, village forests and special easement forests in the northern peninsula were classified into the Nation Forest without Administration caused by the informality and arbitrariness of the survey. Nevertheless, the General-Government of Korea used the results of the survey for establishing the forest policy on the classification of the forest land ownership in Korea at that time. The "Comments on the Classification of Forest Land Ownership in Korea(1910)" was based upon the results of the survey as mentioned above. The comments was realized as colonial forest policy through the Forest Ordinance in 1911 and a series of policies consolidating the modern forest ownership. To conclude, the "Forest Survey Project" was used to establish colonial forest policy in the early of the General-Government of Korea while its accuracy was truly low. Moreover, the "Comments on the Classification of Forest Land Ownership in Korea" had a great influence on the formulating the directions and details of colonial forest policy in Korea under the rule of Japanese Imperialism.

Objective: We compared the level of blood cadmium exposure with health impacts by using data from a survey of residents near an abandoned mine and a national health survey. Methods: For this study, we used data from 7,046 individuals who participated in the Health Effects Survey of Abandoned Metal Mines (AMS, 2008-2011) and 6,871 individuals who participated in the Korea National Health and Nutrition Examination Survey IV-VI (KNHANES, 2008-2013). To evaluate the health impacts, the quartiles (S1 to S4) were classified according to blood cadmium concentration, and then the odds ratios of S2 to S4 over S1 for exceeding the reference values of renal function, blood pressure, and bone density were compared. Similarly, the odds ratio of AMS over KNHANES was confirmed. Results: In the AMS, adjusted for general characteristics, the geometric mean of blood cadmium concentration was 1.34 ㎍/L, which was statistically significantly higher than that of the KNHANES 1.22 ㎍/L (p<0.001). In the integrated data of AMS and KNHANES, the estimated odds ratio of S4 over S1 for exceeding the reference value was found to be 1.70 for serum creatinine, 1.71 for hypertension, and a T-score 2.02 for the tarsal bone. They were all statistically significant. Conclusion: Residents around abandoned metal mines had a higher blood cadmium concentration than the general population, and the odds for exceeding the reference values were higher for some health indicators. Continuous biomonitoring should be conducted for vulnerable areas such as around abandoned metal mines, and measures to reduce cadmium exposure and management of chronic diseases are needed.

Subjects in this study comprised of general public (907), high school students (772), individuals associated with Oriental medicine (660), and 60 majoring in western medicine, totalling 2,413 individuals. Survey was conducted on the necessity of establishing Oriental medicine school at the national university level and the following result were obtained: - 78.3% (1847 individuals) were in favor of establishing Oriental medicine school at the national university level. - For the validity of establishment, responders expressed opinions of standard and virtuous education, higher quality education, standardized practice, research on difficult to cure diseases, and obtaining competitiveness in the world market. - One to three schools were considered as an appropriate number of schools with less than 80 students per class, Class size may be adjusted from existing schools (52.5% favored decrease in size) and (46.3% favored increase in size). - Educational and research facilities must be accopanied with schools of Oriental medicine as well as clinical training facilities, herbal pharmaceutical research centers, and fundamental medical centers. - Many favored 6 year curriculum as the most appropriate system and the school of Oriental medicine should be established within the university. Based on the information gathered in this survey, we may recognize the limitations of Oriental medicine schools at the private institutional level and support the establishment of Oriental medicine schools at th national university level. This establishment may play as a steeping stone for advancement in education, standardization of research and treatment, and commercialization of Oriental medicine of benefit the general public.

This study investigates the implementation of the Converged Science, and what teachers and students think of it in order to understand how it is taking root in schools. The results identify ways in which the new curriculum can establish itself in schools. One hundred and two science teachers, who had participated in the mandatory workshop for the 2009 Amended Course of Science, were given the first survey regarding their general perception of the converged science curriculum. A year after the first implementation of the new curriculum, one hundred and seventy one science teachers were given the second survey in order to determine their general perception and actual results in the classrooms. A similar survey was given to one hundred and forty nine tenth grade students. In addition, one hundred and forty eight tenth grade students, who had experienced the new science curriculum, took part in another survey revealing their general thoughts the course. The results show that the teachers' responses are rarely positive. The teachers claimed that the contents were too extensive while the level of fundamental concepts were too rigorous for tenth graders. They also asserted that the contents contained too much of a particular subject, and that it is necessary to lower the level of rigor. With regard to the level of unification of converged science textbooks, the teachers expressed that they are still slightly inadequate. The subject of science in the seventh curricula was criticized due to its lack of convergence: over 90% of the respondents answered negatively. On the other hand, the students responded more positively: they said that the new converged science was difficult to learn, but was interesting. In Busan, most high schools adopted the new curriculum in the first year when it was introduced for the first time. In most cases (over 80%), several teachers divided and taught the contents either according to their majors or regardless of their majors.

The purpose of the survey was to find out the prevalence rate and related factors for low back pain of nurses and to develop educational program for prevention of the low back pain. The subjects of the survey were 593 nurses of general hospitals in Tae-gu City. The survey was conducted from June 10, 1994 to October 3, 1994. The questionnaire included 34 question items concerning general characteristics, factors related to low back pain, physical nursing activities, and characteristics of low back pain. The results were as follows : 1. Among 593 of subjects, the prevalence rate of low back pain showed 62.1%. 2. In relation of health related life activities and low back pain prevalence, self-reported health state was highly significant(P=.000). 3. In relation of work environmental factors and low back pain prevalence, job satisfaction (P=.026), job stress(P=.020), and workload(P=.002) were significant. 4. In relation of physical nursing activities and low back pain prevalence, bending (P=.000), trunk twisting(P=.003), stretching(P=.006), and pulling and pushing(P=.046) were significant. 5. Physical nursing activities inducing back stress was varicant according to wards. The results of this study pointed out that the subjects' low back pain prevalence was related to the work-related physiologic and psychologic factors. Therefore, for the effective prevention of low back pain, both practicing the body mechanics and raising the morale of the nurses are needed in educational program.

Objectives: The purpose of this study was to investigate the influence of demographic characteristics and oral health status on unmet dental needs among preschool children and to provide a basis for improvement of the dental care equality and accessibility using data from the $6^{th}$ National Health and Nutrition Survey. Methods: This study was performed using data collected from the $6^{th}$ National Health and Nutrition Survey. The subjects were 1,472 out of 22,940 people, who participated in the survey and under went oral examination. IBM SPSS Statistics (Version 20.0) was used for statistical analyses based on the complex sampling design. Frequency analysis was performed to determine the distribution of unmet dental needs according to the characteristics of the subjects. The Rao-Scott ${\chi}^2$ test was performed to examine the relationship of unmet dental needs with general characteristics and health- and oral health-related variables. Relevant factors were determined using binary logistic regression analysis. Results: The factors that had statistically significant relations with unmet dental needs included age, medical insurance, household income, limited physical activity, history of dental caries in deciduous teeth, and subjective health status. Logistic regression analysis of complex samples was conducted to determine factors related to unmet dental needs. The results of analysis showed that limited physical activity and history of dental caries in deciduous teeth were related to unmet dental needs. Conclusions: The results show the factors affecting, and the reasons for, the unmet dental needs of preschool children. Future studies are needed to develop national projects and oral health education reforms to address inequalities in preschool children's dental care.

Purpose: This study utilizes big data from the 8th (2021) National Health and Nutrition Examination Survey to determine first, the relationship between chewing discomfort in the elderly and some systemic diseases and second, whether oral diseases and oral health problems are related to systemic diseases. Since this may have an impact, we aim to provide basic data to facilitate the expansion and emphasize the importance of integrated health management education. Methods: Original data from the 8th (2021) National Health and Nutrition Survey, conducted by the Korea Centers for Disease Control and Prevention, were analyzed using SPSS Version 21.0 (IBM). A complex sample frequency analysis was conducted to confirm the general and health-related characteristics of the study subjects, and a complex sample cross-analysis was conducted to determine chewing discomfort according to both general and health-related characteristics. Complex sample multiple logistic regression analysis was conducted to determine the effect on chewing discomfort. Results: In order to analyze the factors that affect chewing discomfort, the general characteristics that showed significant differences in chewing discomfort were adjusted for age, personal income, education level, basic livelihood security, high blood pressure, subjective health status, and subjective oral health. It was found that the condition had a statistically significant effect on chewing discomfort. Conclusion: The findings of this study demonstrate that high blood pressure, subjective health status, and subjective oral health status affect chewing discomfort; hence, measures such as developing and operating programs to improve national oral health are needed. We hope that our study will be used as basic data for research into chewing discomfort and systemic diseases in the elderly.

Background: Police officers are an occupational group with a high risk of developing musculoskeletal, cardiovascular, and mental diseases because of the nature of their work. This study aimed to gain an understanding of job-related health risks by comparing overall health awareness, presence of physical and mental disabilities and their causes, medical use patterns, and quality of life of the general public through a survey. Methods: In this comparative study, police officer data were collected through a survey conducted from October 1, 2022, to November 15, 2022, and general public data from the 8th National Health and Nutrition Examination Survey of Korea were used for comparison. Results: Police officers' health perception of physical or mental disabilities was significantly more negative than that of the general public because of their work characteristics, patterns, and functions. In addition, police officers with disabilities had severe work and daily living limitations, and their awareness of their overall quality of life was low enough to warrant alarm. Despite their high rates of seeking treatment in medical institutions, continuous medical use was limited. Conclusion: More research on major diseases to which police officers are at risk of exposure is necessary to analyze risk factors and accumulate related data to systematize health management. In addition, Korean medicine treatment techniques with excellent disease prevention are recommended for the health management of police officers.

The purpose of this study was to find out the restructuring strategy for five provincial hospitals through the business analysis and survey of the service area. Through the survey of the service area of 5 hospitals. service area was classified into three groups, such as underserved area, adequate area, and overserved area. The strategy for the restructuring the clinical departments was set up based on the result of the business analysis and characteristics of the service area. The result of the study was as follows; 1) Whether or not a provincial hospital has specialized in specific area according to the circumstances and the needs of the community was the major factor influencing on the operating result of the hospital. 2) Provincial hospitals at the underserved area has to invest according to the changes of the occupancy rate and increasing pattern of the number of patients while maintaining the status as a general hospital. 3) Provincial hospitals at the adequate area has to lower the grade from the general hospital down to the hospital first and has to upgrade the competency through the restructuring the clinical departments and investment in specific area. 4) Provincial hospitals at the overserved area has to lower the grade from the general hospital down to the hospital first and has to seek ways to change the hospital fundamentally into geriatric hospital, pneumoconiosis hospital or psychiatric hospital etc. Provincial hospitals incapable to compete with private hospitals and clinics has to lower the grade from the general hospital down to the hospital first, to specialize in specific area and to restructure some clinical departments into rental base or self-operating basis. In case such methods are judged not so good solution, provincial hospitals has to find out ways such as shut-down of several departments or operating under the attending system.
