Objectives: Pig farmers are known as the high risk group for the zoonoses, but the study for pig farmers to zoonoses has been rare in Korea. So we surveyed the awareness on zoonoses among pig farmers to suggest directions for education. Methods: We visited four regional spots (Gyeongsangnam-do, Gyeongsangbuk-do, Jeollanam-do, and Chungcheongnam-do) where the self education programs of Korea pork producers were convened. We conducted a questionnaire survey of the general, work-related characteristics and the awareness on zoonoses among 278 pig farmers. Results: The awareness rate of zoonoses itself, brucellosis, tuberculosis and salmonellosis were 52.9%, 85.6%, 87.8%, 89.6%, respectively. The awareness rate of the content related to zoonoses, "Human can be infected by the disease of pig", was 46.9%. Awareness rate of zoonoses tended to increase as the school career, and awareness rate of salmonellosis tended to increase as working duration of pig raising. Conclusions: The pig is the principal reservoir of zoonoses. Therefore, effective working guidelines to prevent zoonoses for pig farmers must be developed and an educational program on zoonoses is needed for pig farmers. Furthermore, publicity activities about the prevention of zoonoses are needed for high-risk groups.

Internet, a world wide network of computers, is considered as a sea of information because it allows people to share information beyond the barriors of time and space. However, in spite of the unmeasurable potential applications of the internet, its use in the field of biology education has been extremely limited mainly due to the scarcity of good biology-related sites. In order to provide useful guidelines for constructing user-friendly study sites, which can help high school students with different intellectual levels to study biology, comparative studies were performed on selected educational sites. Initially, hundreds of related sites were examined, and, subsequently, four distinct sites were selected not only because they are well organized, but also because each is unique in its contents. Also, a survey was carried out against the users of each site. The survey results indicated that the high school students regard the web-based biology study tools as effective teaching methods although there might be some bias in criteria for selecting target sites. In addition to the detailed biology topics and the related biology informations, multimedia data including pictures, animations and movies are found to be one of the important ingredients for desirable biology study sites. Thus, the inclusion of multimedia components should also be considered when developing a systematic biology study site. Overall, the role of the cyber space is expected to become more and more important. Since the development of the user-satisfied and self-guided sites require interdisciplinary collaborational efforts which should be made to promote extensive communication among teachers, education professionals, and computer engineers. Furthermore, the introduction of good biology study sites to the students by their teachers is also important factor for the successful web-based education.

This study is to make suggestion for developing textbook systematically by analyzing biological contents and organization in science textbooks which are important instructional media to accomplish objectives of the 6th middle school science curriculum. The inclusiveness degree of the 6th science educational objectives reflected in the textbooks was analyzed by Klopfer's and the Korean Educational Department's objectives taxonomy. And the biological contents and the organization of the science textbook were analyzed by learner, subject matter, and society dimensions which are selecting criteria for curriculum objectives suggested in Tyler's curriculum model. The analyzed results are as follows: 1. The inclusiveness degree of the educational objectives was very low. 2. Regarding the dimension of learner, the concepts of formal operational cognitive level were much increased as grade becomes higher. And the degree of learner's interests reflected on the learning topics and domains was very low. 3. Regarding the dimension of subject matter, the concept-centered learning was increased, in relation to inquiry learning as grade becomes higher. The analyzed results of inquiry subskills showed that observation, classification, and recording skills in 1st grade, observation and operation skills in 2nd grade, and interpreting data skills in 3rd grade were centered. As the problems and processes were presented, so most of inquiry activities had low openness scale. The learning contexts were organized into discipline-centered in relation to real life. 4. Regarding society dimension, the learning topics of environments and health were much presented. but those of biotechnology and career were presented scarcely. And most learning topics related society dimension were organized in textbooks of the 2nd and 3rd grade. These suggested that to accomplish curriculum objectives effectively. the inclusiveness degree of educational objectives is to increase and, the contents and organization of textbook were constructed harmoniously in aspects of learner, subject matter and society dimensions.
Although the perfomance indicators of the nuclear power plants in Korea show optimal, it requires detailed analysis and discussion centered on the radiation dose. As analysis methods, analysis on the radiation dose of nuclear power plants over the past five years was assessed by comparing the relevant radiation dose of radiation workers and per capita average annual radiation dose of the world's major nuclear power stations was also analyzed. The radiation workers over the annual radiation dose limit of 50 mSv were not. The contrast ratio of the radiation exposure according to the reactor type was the normal operation of PHWR was 6.2% higher than those of the PWR. This shows the radiation work of PHWR during normal driving operation is much more than those of PWR. According to the Performance Indicators of the World Association of Nuclear Operator, the annual radiation dose per unit in 2013 showed 527 man-mSv of Korea is the best country among the major nuclear power generating states, the world average was 725 man-mSv. The annual per capita radiation dose is about 80% less than 1 mSv of the public dose limit and also the average per capita dose showed a very low level as 0.82 mSv. Workers in related organizations showed 1.07 mSv, the non-destructive inspection agency workers showed 3.87 mSv. The remarkable results were due to radiation reduced program such as development of radiation shielding and radiation protection. In conclusion, the radiation exposured dose of nuclear power plants workers in Korea showed a trend which is ideally reduced. But more are expected to be difficul and the psychological insecurity against the operation of the nuclear power plants is existed to the residents near the nuclear power plants. So the radiation dose reduction policy and radiation dose follow up study of nuclear power plants will be continously excuted.
In 2017, the world's first WIG ship (WIG: Wing In-Ground) pilot's license written test was conducted in Korea. The WIG ship is a ship that combines the characteristics of ships and airplanes. Therefore, the pilot of the WIG ship was allowed to apply only for those who had the aircraft pilot's license and the 6th class marine nautical license. The WIG ship pilot's license system was first introduced by Korea, so there are no international standards for the license system, and the introduction of a domestic qualification system also requires institutional arrangements due to various restrictions such as pilot training. However, in order to become a valuable industry as a future growth engine for the ocean, several urgent problems need to be solved, and that is the training of manpower for WIG ships. Therefore, I reviewed the institutional issues related to pilot training as this subject. Since 2001, various countries around the world have been discussing this issue, centering on IMO, and Korea has continued to participate and cooperate in IMO meetings. And the national qualification test for surface flying ships was conducted in Korea from 2011. However, there are still problems to be solved, and I pointed out the advancement of the manpower training system, the education and training system, and the designated national educational institution system. As a solution to this, it was suggested through the improvement of the license system and the operation of designated educational institutions. Among these solutions, I believe that the best way is to entrust the operation of designated national educational institutions to private educational institutions. However, I propose a plan that the government entrusts to private educational institutions, but the government is responsible for licensing and supervision. WIG ship will be a new market for the aviation industry and aviation workers.

This study was performed to estimate the prevalence and the risk factors of arthritis in Andong rural area in 2003. The subjects were 1,462 people (544 males, 818 females) aged 45 years and over. The arthritis group was composed of 322 people (72 males, 250 females), diagnosed by doctor or self-diagnosed by the symptoms. Prevalence of arthritis was higher in female (27.2%) compared to male (13.2%). Mean age of arthritis group was significantly higher than that of normal group (male 66.2 vs 62.8, female 62.6 vs 60.1, p<0.001). The anthropometric measurements, such as % body fat, body mass index (BMI), and waist circumference, and the biochemical measurements, such as plasma triglyceride and total cholesterol level, were significantly higher only in female (not in male) arthritis group than those in normal group. Health related lifestyle factors, such as smoking, alcohol drinking, and exercise, were not different between both groups. The risk factors for arthritis were analyzed using the multiple logistic regression method and expressed as odds ratio (OR). The results showed that female compared to male (OR=1.983), over 65 years compared to 45$\sim$64 years (male OR=2.769 and female OR=1.461), and obese female subjects (not for male) by % body fat ($\geq$32% OR=2.035) or BMI ($\geq$25 kg/$m^2$ OR=1.556) showed significantly higher risk factors for arthritis. Regarding nutrient intakes, higher intakes of fat (OR=1.443), calcium (OR=1.503), iron (OR=1.518) and vitamin A (OR=1.390) in female seemed to be risk factors. In contrast to female, higher intakes of vitamin A (OR=0.526) and riboflavin (OR=0.582) seemed to decrease the risk for arthritis in male. This study revealed that the prevalence of arthritis was significantly higher in female and aged individuals. Also, in order to decrease the prevalence and/or prevention of arthritis, female should prevent overfatness and decrease some nutrient intakes, while male should increase their intakes.
This study is conducted to develop an efficient transformation system via particle bombardment with PLBs (Protocorm-like bodies) in Cymbidium. For this, pCAMBIA3301 vector which carries a herbicide-resistant bar gene and gus gene as a reporter gene was used for transformation with Cymbidium cultivars 'Youngflower ${\times}$ masako' line. To select transformants, proper concentration of herbicide, PPT (phosphinotricin), should be determined. As a result, 5 mg/l of PPT was selected as a proper concentration. Further, proper conditions for particle bombardment were determined to obtain a high frequency of transformation. Results showed that 1.0 ${\mu}g$ of DNA concentration, 1,100 and 1,350 psi for helium gas pressure, 1.0 ${\mu}m$ of gold particle and 6 cm of target distance showed the best result for the particle bombardment experiment. Also, pre-treatment with combination 0.2 M sorbitol and 0.2 M mannitol for 4 hrs prior to genetic transformation increased the transformation efficiency up to 2.5 times. Using transformation system developed in this study, 3.2 ~ 4.0 transgenic cymbidium plants can be produced from 100 bombarded PLBs on average. Putative transgenic plants produced in this system confirmed the presence of the bar gene by PCR analysis. Also, leaves from randomely selected five transgenic lines were applied for Basta solution (0.5% v/v) to check the resistance to the PPT herbicide. As a result, three of them showed resistance and one of them showed the strongest resistance with the maintenance of green color as non-transformed plants showed. Using this established transformation system, more genes of interests can be introduced into Cymbidium plants by genetic transformation in the future.
The purpose of this study was to compare the effect of several reheating treatments (immersing the package into hot water, heating the soup in the pot and convection ovens after taking out of the opened package. heating the soup package in microwave) on the sensory characteristics of cook-chill and sous-vide spinach soup. Sensory evaluations were made on 5 sensory attributes by a 12-member panel using quantitative descriptive analysis(QDA). The fresh cooked spinach soup had a significantly(p<0.01) higher score in color than the reheated sous-vide one. The latter, however, had a significantly(p<0.05) higher score in taste than the former. Overall acceptability of the sous-vide spinach soup was not different from that of fresh cooked one, which supports the potential of the product in foodservice operation for the efficient management of meal plan. Reheating treatments didn't show any differences in taste, flavor, color, texture, appearance and overall acceptability. Therefore, any reheating treatment nay be used for cook-chill and sous-vide spinach soup.

The aim of this study was to analyse and conduct the comprehensive geriatric assessment for the elderly in rural area. The subjects were 388 older people aged 65 years or older living in the community. Data for comprehensive assessment such as physical, mental, functional, social and environmental conditions were collected from January to February, 2001 through a person-to-person interview. Of the total 388 olders, 169(43.6%) were men and 219(56.4%) were women. Mean ages of men and women were $73.5{\pm}6.4$ and $74.0{\pm}6.2$ years respectively. Three common diseases of the elderly were arthralgia(51.6%), chronic back pain(33.2%) and hypertension(18.6%), and higher in women than in men. Impairment rate of vision, hearing and bowel or bladder control was 59.0%, 20.1%, and 28.4% respectively. But that of lover extremities 3.4%. In terms of cognitive function, short term memory loss was found in 33.7% of males and 44.7% of females. The percentage of fully independent in the six ADL items was 72.2% in men and 58.9% in women. In the social supportive system, 49.5% of the elderly were living with spouse, and 22.9% living alone, 26.3% having care giver. These results will provide basic data for the development of community-based health program, which gives appropriate health service for the elderly living in the community.

Objectives:To review the history of the development and current status of Korean Child and Adolescent Psychiatry and to propose the future tasks at this 20th anniversary of Korean Academy of Child and Adolescent Psychiatry. Methods:Records and publications of Korean Academy, personal communications with senior members of the Academy, the author's recollections and memoirs. Results:Korean Child Psychiatry started with opening Child Psychiatry Clinic at Seoul National University Hospital in 1979 and establishing Division of Child and Adolescent Psychiatry at the same hospital in 1980. A Child Psychiatry Study Group was formed in 1983 and it transformed into Korean Academy of Child and Adolescent Psychiatry in 1986. In the past 20 years, Korean child and adolescent psychiatry made an impressive progress and contributed significantly to the development of Korean medicine as well as to the establishment of child mental health service. There are 77 board-certified and 48 board-eligible child psychiatrists, and 18 child psychiatry fellows are in training as of 2003. Main forces of this successful introduction of child psychiatry are 1) 7 child psychiatry training centers at major university hospitals, 2) publication of Korean Journal of Child and Adolescent Psychiatry in 1990, 3) the establishment child psychiatry board certification system in 1996. Korean child psychiatry has extended its role in the international child psychiatry and took leadership in establishing Asian Society of Child and Adolescent Psychiatry and Allied Professions(ASCAPAP). Conclusion:Korean child psychiatry has achieved a remarkable progress for the past 20 years and is currently producing 15 or more child psychiatry each year. However, there are needs of more active involvements in adolescent problems, more active consultation-liaison services at general hospitals as well as community mental health institutions. More school consultation and preventive educational services are desired. There is a urgent need of carrying out more empirical studies with strong scientific rigor. Korean Academy should pay attention and provide assistance to the development of child psychiatry service in other countries in Asia.
