The Purpose of this study was to investigate college students' attitude toward body weight control, health-related lifestyle and dietary behavior by their perception on body image and obesity index. The subjects were 871 nation- wide college students (330 male and 541 female students) participating in a nutritional education program via internet- A cross-sectional survey was conducted using a self-administered questionnaire via internet. The data were analyzed by a SPSS 10.0 program. Height and weight (p < 0.05), and the distribution of obesity index (p < 0.001) showed significant differences between male and female college students. As for self perception on body image, the necessity of body weight control and the experience of efforts to change the body weight, there were significant differences between male and female college students (p < 0.001). There were significant differences among groups by obesity index in the hours of exercise (p < 0.01), drinking (p < 0.01) and smoking (P < 0.001). As for methods of body weight control, all the groups by obesity index thought that program of body weight control by diet company is the most desirable method. Therefore, we must recognize that it is hard to correct health problems resulting from wrong lifestyle and dietary behavior fixed during college life and prepare a system for college students to obtain correct lifestyle and dietary behavior.

This study aims to make a research on the secondary school education of geography and the system of teacher training in Belgium, focused on the case of Francophone Community. What has been made clear by this research can be summed up as follows. The first two years of the secondary school offer two hours of 'environment education', per week, which can be categorized into the learning of living geography, in that at this stage students learn how to observe the geographic phenomena in their daily life and pigeonhole them. The two years of the second stage of the secondary school offer one hour of 'world geography' which actually is focused on the district of Europe and Russia. The two years of the third stage of the secondary school offer an advanced course of geography which aims to teach systematically the physical geography and the human geography. A remarkable change in geographic education in Belgium is that in the wake of the Revision Act of the secondary school education, textbooks were replaced by other teaching manuals adapted to the regional condition by the teachers. This may result in a wide gap of achievements in geography according to the conditions of educational establishments. Another notable change is that the stress of geographic education tends to be placed on the ability of acquiring practical geographic knowledge rather than the geographic information itself. And it is also another marked tendency that most learning activities in geography class are conducted on the basis of student-centered and the method of investigation. Teachers of the lower secondary schools in Belgium are trained in the School of Education as multi-major teachers, such as a teacher for biology-chemistry-geography or a teacher for history-sociology-geography. Teachers of the higher secondary school education are trained in the Department of Teacher Education in universities as solo-major teachers in that they are required to know more deeply to teach an advanced course of geography in the higher secondary schools. To improve the teacher education many folds of policies are adopted. One is that many in-service teachers are officially put into services of guiding and teaching teacher training. Another is that faculty members in charge of teacher training course are trying to level up the qualifications of teachers by rigorous disciplining.

The extraction of trace cobalt, copper, nickel, cadmium, lead and zinc in urine samples of organic and alkali metal matrix into chloroform by the complex with a dithizone was studied for graphite furnace AAS determination. Various experimental conditions such as the pretreatment of urine, the pH of sample solution, and dithizone concentration in a solvent were optimized for the effective extraction, and some essential conditions were also studied for the back-extraction and digestion as well. All organic materials in 100 mL urine were destructed by the digestion with conc. $HNO_3$ 30 mL and 30% $H_2O_2$ 50 mL. Here, $H_2O_2$ was added dropwise with each 5.0 mL, serially. Analytes were extracted into 15.0 mL chloroform of 0.1% dithizone from the digested urine at pH 8.0 by shaking for 90 minutes. The pH was adjusted with a commercial buffer solution. Among analytes, cadmium, lead and zinc were back-extracted to 10.00 mL of 0.2 M $HNO_3$ from the solvent for the determination, and after the organic solvent was evaporated, others were dissolved with $HNO_3-H_2O_2$ and diluted to 10.00 mL with a deionized water. Synthetic digested urines were used to obtain optimum conditions and to plot calibration-eurves. Average recoveries of 77 to 109% for each element were obtained in sample solutions in which given amounts of analytes were added, and detection limits were Cd 0.09, Pb 0.59, Zn 0.18, Co 0.24, Cu 1.3 and Ni 1.7 ng/mL, respectively. It was concluded that this method could be applied for the determination of heavy elements in urine samples without any interferences of organic materials and major alkaline elements.

College level educational training system for the allied health manpower in the country is one of the oldest junior college education programs, and has been developed at very steady phase. Since the school years of the programs limited for 2 to 3 years by the education related law, qualification of the manpower is insufficient to meet the rapidly changing needs in the field of allied health and medicine. The system is comparable with that of developed countries where 4-year baccalaureate degree programs are basically required to be an allied health personnel. Thus, education and training background of allied health program graduates of the country confronts the barriers in competition and cooperation with the graduates of foreign countries at equal basis. Beside, junior college graduates can hardly find the way through advanced courses at 4-year colleges in their specialties except a few programs such as environmental sicience or courses in hygiene. It has long been sought to develop the education and training programs for junior college graduates. Some of them are already materilized and some show remarkable progress while some need to tackle. Wide opening of the opportunity to enroll extensive education program for the junior college graduates of allied health science majors in 4-year colleges with eventual grant of bachelor's degree for those who successfully completed the programs should soon be substantiated. The study was focused to emphasize the necessity of the extensive education and training for the junior college graduate allied health manpower, and to show possibility of the education program development in connection with the 4-year degree granting education programs. The outcome of the study can be summarized as followings. 1. A total number of graduates from eight allied health sciences related programs of junior colleges by the year of 1995 are 109,320. 2. According to the survey report analysed through questionnaires, 99.7% of respondents including administrative deans and professors of junior colleges agreed with the establishment of extensive education and training programs in junior colleges. 53.9% of administrative deans, 52.9% of professors and 47.6% of the graduates expected that it is possible to learn more about their majors, and to earn bachelor's degree through the extensive education programs. Other opinions include that the programs can provide supplementary opportunities to fortify in the area of basic life science, and development of research and technology. 3. It was also found through the survey that 91.2% of the deans, 87.8% of the professors and 68.2% of the graduates responded that the most appropriate organizations to open the extensive education and training programs for allied health manpower are junior colleges where allied health personnel are taught and trained. The majority of the respondents agreed that the acceptable number of credits offered for the previous 2-year junior college graduates are $50\sim60$, and those for the current 3-year graduates are $20\sim30$ units. 4. It was strongly suggested through the survey that baccalaureate degree should be granted for those who successfully completed the extensive courses. The suggestion was claimed by 94.1% of the deans, 89.4% of the professors and 83.4% of the graduates. 5. The model curricula for the extensive education and training programs for the allied health manpower are designed for the purpose of broad capability in practice, enrichment of knowledge and promotion of proficiency for the self access in the major areas. 6. To meet the universal standards of allied health education and training program, it is recommended that opening of the curricula for the extensive, and as well as intensive, courses within junior colleges(continuation education institute) should be materialized. The special baccalaureate degree programs within junior colleges are also recommended to accommodate the junior college graduates and to grant the degree fellowing successful completion of the courses. As a part of the education revolution in progress, the school years at junior college level should be flexible depending upon the nature of course and trend of the universe. For instance, the school years for the allied health manpower should be extended to two to four years from current two to three years.

Purpose: $^{18}F$-FDG PET/CT has been known a useful modality to diagnose high-glucose-using cells such as cancer cells by glucose metabolism of FDG. Mainly, FDG takes on cancer and inflammatory cells; However, There have been FDG uptakes on normal tissues by individual physiological characteristics, occasionally. Especially, in fertile females, unusual FDG uptake of breast changes as the menstrual cycle, and disturb diagnosis. Therefore, the study aimed to evaluate the change of breast FDG uptake in menstrual cycle on $^{18}F$-FDG PET/CT. Materials and Methods: 160 females ($34{\pm}3.5$ years old) who do not undergo a gynecologic anamnesis and have regular menstrual cycle over the previous 6 months were examined, from March 2009 to February 2010. They were divided 4 groups (each 40 patients) as flow phase, proliferative phase, ovulatory phase and secretory phase using Pregnancy Calculator 0.14. and history taking. Discovery Ste (GE Healthcare, Milwaukee, Mi, USA) was used as PET/CT. We analyzed SUVs on accumulated region on breast, and 3 nuclear medicine specialists did the Blind test. Results: SUVs on the Breast were flow phase ($1.64{\pm}0.25$), proliferative phase ($0.93{\pm}0.28$), ovulatory phase ($1.66{\pm}0.26$) and secretory phase ($1.77{\pm}0.28$). It showed high uptake value in secretory, flow phase and ovulatory phase (p<0.05). In gross analysis, the accumulation of breast was divided into 3 grades as comparing with lung and liver. The breast's uptake was equal to lung (Grade I); between lung and liver (Grade II); equal to or greater than liver (Grade III). The results showed high uptake value in secretory, flow phase and ovulatory phase (p<0.05). Conclusion: In fertile females, FDG uptake of breast changed as menstrual cycle, and it available to diagnose breast disease. Therefore, we consider reducing false-negative finding of breast disease, by doing examination on appropriate period through history taking about individual menstrual cycle.

Purpose: There are various methods to diagnose hemangioma, such as ultrasonography (US), computed tomography (CT), magnetic resonance imaging (MRI) and nuclear medicine. However, by development of SPECT imaging, the blood-pool scan using $^{99m}Tc$-labeled red blood cell has been used, because it was non-invasive and the most economical method. Therefore, in this study, we proposed that the usefulness of $^{99m}Tc$-RBC scan and SPECT of the head and neck to diagnose unlocated hemangiomas. Materials and Methods: $^{99m}Tc$-RBC scan and SPECT was performed on 6 patients with doubtful hemangioma (4 person, head; 1 person, neck; 1 person, another). We labeled radiopharmaceutical using modified in vivo method and then, centrifuged it to remove plasma. After a bolus injection of tracer, dynamic perfusion flow images were acquired. Then, anterior, posterior, both lateral static blood-pool images were obtained as early and 4 hours delayed. SPECT was progressed 64 projections per 30 seconds. Each image was interpreted by physicians, Nuclear medicine specialist, and technologist blinded to patient's data. Results: In 5 patients of all the radioactivity of doubtful site didn't change in flow images, but, in blood-pool, delayed and SPECT images, it was increased. So, it was a typical hemangioma finding. The size of lesion was over 2 cm, and it could discriminate as comparing to the delayed and SPECT imaging. On the other hand, in 1 patient, the radioactivity was increased in blood-pool images, but, not in delayed and SPECT images, so, it was proved no hemangioma. Conclusion: Using $^{99m}Tc$-RBC Scan and SPECT, we could diagnose the hemangiomas in head and neck, as well as, liver, more non-invasive, economical, and easy. Therefore, it considered that $^{99m}Tc$-RBC scan and SPECT would offer more useful information for diagnosis of hemangioma, rather than otherimaging such as US, CT, MRI.

To describe the comparative awareness between media and industry, we conducted a survey with a professional group including 28 food safety managers at food corporations and 17 food journalists to find out the differences in perception of 'reporting terms' and 'correspondence terms' when food safety incident occurs. We surveyed by questionnaire methods and did the statistical analysis by SPSS. The results showed that 70.6% of the journalists and 92.9% of the corporation workers answered 'yes indeed' about the question whether the media has a great influence when food safety incident occurs. In the perception that use of the stimulating terms of the media was the cause of company damage, 83% of the corporate workers answered 'yes indeed', and 70.6% of the journalists answered 'yes'. It means that both groups agreed on stimulating terms causing company damage. In the question whether the 'reporting terms' of the media and the 'correspondence terms' of the government and academia made a difference in the consumers' perception and the spread of the incident, 92.9% of the corporate workers and 35.3% of the journalists answered 'yes indeed'. It means that both groups showed a common opinion that the difference in choice of words expanded the perception of consumers, and the spread of the incident. However, the corporate workers agreed with this in a more serious manner than the journalist group. In standardization of 'reporting terms' and restricting use, corporate workers were overall at a positive stand while journalists showed a big difference in opinion within the group. In conclusion, it is necessary to establish a measure to standardize the terms used by corporations, journalists, and professionals in order to decrease the differences of terms and the damage of consumers and the company when food safety incident occurs.

The Human gene testing act (GenDG) in Germany starts from the characteristic features of gene testing, i.e. dualisting structure consisted of anlaysis on the one side and the interpretation on the other side. The linguistic distincion of 'testing', 'anlaysis' and 'judgment' in the act is a fine example. Another important basis of the regulation is the ideological purpose of the law, that is information autonomy. The normative texts as such and the founding principle are the basis of the classification of testing types. Especially in the case of gene testing for medical purpose is classified into testing for diagnostic purpose and predictive purpose. However, those two types are not always clearly differentiated because the predictive value of testing is common in both types. In the legal regulation of gene testing it is therefore important to manage the uncertainty and subjectivity which are inherent in the gene-analysis and the judgment. In GenDG the system ensuring the quality of analysis is set up and GEKO(Commity for gene tisting) based on the section 23 of GenDG concretes the criterium of validity through guidelines. It is also very important in the case of gene testing for medical purpose to set up the system for ensurement of procedural rationality of the interpretation. The interpretation of the results of analysis has a wide spectrum because of the consistent development of technology on the one side and different understandings of different subjects who performs gene testings. Therefore the process should include the communication process for patients in oder that he or she could understand the meaning of gene testing and make plans of life. In GenDG the process of genetic counselling and GEKO concretes the regulation very precisely. The regulation as such in GenDG seems to be very suggestive to Korean legal polic concerning the gene testing.

Before 1990's, Korea had only few colleges that had film and film related majors. As Korean film industry started its marvelous improvement in both commercial and artistic phase, many colleges were interested in this new academic field. They hurried up to launch this new and profitable major; as a result, Korea now has more than hundred colleges and universities that has film related majors. Each college enumerates numbers of academic courses that may look reasonable; they have almost every course a fine film school should provide such as film theory, production, and performance in film. Lots of film schools offer lots of film courses; and they look alike. One unique thing in film major is its vast sub fields and categories. After you decide to study film, you have to select what specific field in film you want to study. Studying film theory and film production can be as different as majoring physics and physical education. The problem Korean colleges are dealing with is that there are too much film schools, and moreover those colleges have similar curriculums that just look like a department store that sells everything. One suggestion is specializing its curriculum in which the school can take advantages using their special conditions. San Francisco Art Institute is one of United States well known private film schools, but many people remember this school as a specialized film school in experimental film. San Francisco where this school is located has had many liberal and experimental artists as the city has been supporting and offering them an environment they can concentrate their work. Naturally, the school has world famous faculty members in experimental film, and students who want to study and make experimental film come to this school from all over the world because they know this school would be the best to study experimental film. There are many film schools in metro Los Angeles area; since its location near Hollywood, no wonder these schools concentrate on film producing and film production. They take advantage of their geographical location to hire film industry professional and to focus on commercial feature film productions. What we can do now to adjust the curriculum in film and film related major in Korean colleges is to adapt new standards in this changed film industry. One school can emphasize digital production while another school focuses on digital intermediate process. But if one school tries to both fields or all fields of film major just like we have done so far, the school could not take care of all the equipment and the faculty that the fields would need. Korean film schools should devide the field in film major and concentrate what they selected. Selection and concentration can be and should be applied in Korean film schools.

KoFlux is a Korean network of micrometeorological tower sites that use eddy covariance methods to monitor the cycles of energy, water, and carbon dioxide between the atmosphere and the key terrestrial ecosystems in Korea. KoFlux embraces the mission of AsiaFlux, i.e. to bring Asia's key ecosystems under observation to ensure quality and sustainability of life on earth. The main purposes of KoFlux are to provide (1) an infrastructure to monitor, compile, archive and distribute data for the science community and (2) a forum and short courses for the application and distribution of knowledge and data between scientists including practitioners. The KoFlux community pursues the vision of AsiaFlux, i.e., "thinking community, learning frontiers" by creating information and knowledge of ecosystem science on carbon, water and energy exchanges in key terrestrial ecosystems in Asia, by promoting multidisciplinary cooperations and integration of scientific researches and practices, and by providing the local communities with sustainable ecosystem services. Currently, KoFlux has seven sites in key terrestrial ecosystems (i.e., five sites in Korea and two sites in the Arctic and Antarctic). KoFlux has systemized a standardized data processing based on scrutiny of the data observed from these ecosystems and synthesized the processed data for constructing database for further uses with open access. Through publications, workshops, and training courses on a regular basis, KoFlux has provided an agora for building networks, exchanging information among flux measurement and modelling experts, and educating scientists in flux measurement and data analysis. Despite such persistent initiatives, the collaborative networking is still limited within the KoFlux community. In order to break the walls between different disciplines and boost up partnership and ownership of the network, KoFlux will be housed in the National Center for Agro-Meteorology (NCAM) at Seoul National University in 2011 and provide several core services of NCAM. Such concerted efforts will facilitate the augmentation of the current monitoring network, the education of the next-generation scientists, and the provision of sustainable ecosystem services to our society.
