Objectives: We reviewed the CAREX (CARcinogen EXposure) program designed to estimate the prevalence of occupational exposure to carcinogens and summarized the advantages and limitations of this program. Methods: All literature, including reports on CAREX and the use of CAREX, were reviewed. The keyword search term was CAREX. Additional articles were identified from references cited in articles and reviewed. Results: An exposure information system, CAREX was developed based on data from the Finnish Institute of Occupational Health of Finland and from the US. CAREX has been applied in several countries, including in the EU, in order to estimate national exposure patterns to carcinogens. The initial exposure assessment carried out through CAREX was aimed at estimating exposures over the period of 1990-1993. To estimate the number of workers exposed to carcinogens by using CAREX, reference exposure prevalence from Finland and the United States was computed, which was then reviewed and corrected by national experts. Finally the overall number of workers exposed to carcinogens can be estimated. We found that CAREX has been used in a total of 18 countries. No Asian country has used CAREX. Conclusions: CAREX can be applied not only to estimate the number of workers exposed to carcinogens in Korea, but also to identify high-risk industries with workers most exposed to carcinogens.

We tested for residual pesticide levels in school foodservice agricultural products in Seoul, Korea from 2010 to 2012. A total of 316 samples of 23 different types of agricultural products were analyzed via gas chromatography-nitrogen phosphate detector (GC-NPD), an electron capture detector (GC-${\mu}ECD$), a mass spectrometry detector (GC-MSD), and a high performance liquid chromatography-ultraviolet detector (HPLC-UV). We used multi-analysis methods to analyze 185 different pesticide types. Among the selected agricultural products, residual pesticides were detected in 26 samples (8.2%), of which 6 samples (1.9%) exceeded the Korea Maximum Residue limits (MRLs). We detected pesticide residue in more than 65% of the Chwinamul, while 6 among 9 analyzed samples contained pesticide residue, and 1 sample exceeded the Korea MRLs. Among the 185 kinds of pesticides that we have tested, 18 were detected, while 7 of them were detected more than twice. Data obtained were then used for estimating the potential health risks associated with the exposures to these pesticides. The most critical commodity is carbofuran in the perilla leaves, which has contributed 3.8% to the hazard index (HI). These results showed that the detected pesticides could not be considered as a serious public health problem. Nevertheless, constant supervision is recommended.

The aim of this study was to clarify the physiological and psychological effects of walking around and viewing a lake in a forest environment. The subjects included 11 male Japanese university students (age: $22.0{\pm}1.2$ years) who were randomly assigned to visit either a forest or an urban (control) setting. They were instructed to walk a predetermined 15-min course and to view the setting from a seated position for 15 min. Heart rate variability, heart rate, blood pressure, pulse rate, and salivary cortisol levels were measured to assess the subject's physiological responses to the environment. Four questionnaires (SD method, reports of "refreshed" feeling, POMS, and STAI) were administered to assess the subjects' psychological responses. It was found that walking around and viewing a lake in a forest environment can suppress sympathetic nerve activity, increase parasympathetic nerve activity, and decrease the heart rate, blood pressure, pulse rate, and cortisol levels. In addition, a forest environment can enhance the "comfortable," "soothing," "natural," and "refreshed" feelings, improve the mood state, and reduce anxiety. These results provide scientific evidence of the physiological and psychological effects of forest therapy.

According to the changes of the medical environment of the times, it is necessary to discuss the issues of the doctor's medical guidance and to conduct continuous research so that alternatives can be prepared systematically. Furthermore, in order to enhance the professionalism of radiological technologists and to develop the medical technician system, the new Radiological Technologist Independent Act has been established, which contains the overall contents of the scope of work, professional qualifications, and specialized education of radiological technologists, and provides quality medical services to patients through professional procedures and treatment. In order to increase the level of medical care, the purpose, definition, mission, role, and scope of work specified in the Medical Act, Medical Service Technologists, etc. Act, the Enforcement Decree, and the Enforcement Rules were variously analyzed and new directions were presented. First, the definition of a medical technician should use a generic term so that the factors of conflict and prejudice could be resolved. Second, change the doctor's guide to doctor's prescription; and then legislate the authority to sign and write medical records after examination by radiological technologists, thereby prohibiting unlicensed technicians that seriously endanger patient safety. Third, an accurate definition of radiological technologists' roles should be established; not only selection and management of radiological technologists' work but also procedures and treatment for each radiology field should be specified to suit the current medical system. Fourth, a professional radiological technologists' qualification system and a specialized education system should be established in order to secure human resources that could provide patients trust in procedures and treatment based on professional knowledge and experience in the field of radiology. Fifth, the Education and Evaluation Institute should be operated in Korea education system to educate the professional knowledge and competency for students. In addition, it is necessary to in-depth analysis of foreign cases could be applied to the medical system and education system in Korea; it could strive to nurture systematic human resources.

Objectives: We aimed to examine the association between the relative preference for vegetables and meat and cancer incidence, in a population-based retrospective cohort in Korea. Methods: We included 10,148,131 participants (5,794,124 men; 4,354,007 women) who underwent national health screening between 2004 and 2005 from the National Health Information Database of the National Health Insurance Service (NHIS-NHID). Participants were asked whether they preferred consuming 1) vegetables more often, 2) both vegetables and meat or 3) meat more often. Participants were followed up to Dec. 31, 2017. All cancer and eighteen common cancer cases were identified through the code from the International Classification of Diseases, 10th revision. We estimated sex-specific relative risks and 95% confidence intervals, adjusting for age, body mass index, alcohol consumption, smoking, physical activity, and income level. Results: During an average follow-up of 12.4 years, 714,170 cancer cases were documented. In men, consuming meat more often was associated with lower risk of esophageal, liver, and stomach cancers, but higher risk of lung and kidney cancers. Consuming both vegetables and meat was associated with higher risk of prostate cancer, but with lower risk of esophageal, liver, and stomach cancers in men. In women, consuming meat more often was associated with a higher risk of colorectal cancer and breast, endometrial, and cervical cancers diagnosed before the age of 50. Consuming both vegetables and meat was associated with lower risk of liver cancer in women. Conclusions: Our study suggests a potential link between vegetable and meat intake and cancer incidence in the Korean population. Further investigation on the association between the intake of specific types of vegetables and meat and cancer risk in Korean prospective cohort studies is needed.

This study aims to investigate the differences in burnout, emotional labor strategies, affect intensity, and emotional clarity based on combinations of level of mindfulness and compassion. To achieve this, a total of 137 mental health professionals participated in this study, and they were classified into four groups based on their level of mindfulness and compassion using cluster analysis. Then, the differences among the groups were compared. The results of the multivariate analysis of covariance(MANCOVA) or multivariate analysis of variance(MANOVA) controlling for career experience, showed that the group with high levels of both mindfulness and compassion had the highest levels of positive affect intensity, emotional clarity for self and others, and genuine expression, while having the lowest levels of negative affect intensity, surface acting, and burnout. In comparison to the group with high levels of both mindfulness and compassion, the group with high or low level of either mindfulness or compassion had both positive and negative affect intensity at higher or lower levels. Additionally, they showed lower emotional clarity for self and others, and genuine expression. Conversely, they showed higher levels of surface acting and burnout. The group with low levels of both mindfulness and compassion experienced low levels of positive affect intensity and high levels of negative affect intensity. They also had the lowest levels of emotional clarity for self and others and genuine expression. In addition, they showed that the highest levels of surface acting, and burnout. Based on the results, the study discussed the balanced development of mindfulness and compassion to prevent burnout of professionals in the human service field, including mental health professionals. The implications and limitations of this study were further analyzed in the discussion section, including the direction for future research.

Gabensis village is one of the biggest village In the Wampar Local Level Government area within the Huon Gulf District of Morobe Province with a population of around 3,000. The major staple food is banana which is well complemented by minor staples yam, cassava, Singapore/Chinese taro and sweet potato. Apart from gardening for own consumption, the villagers engage in selling of vegetables, garden staples, cocoa beans, coconuts, timber, chicken, fish and pig meat to supplement their livelihood. Livestock like pigs and chickens are also kept for meat and for commercial purpose. Bettlenut which was once one of the main cash crops has now been overtaken by cocoa due to a disease that had attacked almost the entire bettlenut tree population in the area. Even though the Wau-Bulolo highway cuts through the village and all have access to transport infrastructure, the majority of the population still encounter problems in communication due to poor telecommunication coverage. On average most people earn not more than K50 per week due to constrains in production and marketing among others. Gabensis village has the potential to develop a tourism industry given its natural attraction of Lake Wanam. Beside there is also the natural eel farming and the fish pond at the nearby Potsie village. These natural attractions pose huge tourism potential for the community. As part of government services delivery and development, education and health issues is very much important in the community however there is lack of infrastructural development and poor service delivery especially in the area of health. However, the responsibility is on the community to organize themselves to realize that potential. A well developed agro-ecotourism investments would have positive spillover effects to the community thus contributing towards improving the livelihoods of the many farming families.

As a result of measuring and evaluating 24 units of 10 types of medical ultrasonic equipment in Gwangju using the multipurpose ultrasonic phantom (ATS-539), all 24 units were 100% passed in the non-inspection area, vertical distance measurement, horizontal distance measurement, axial/side resolution, gray tone and dynamic range items. As a result of analyzing the ultrasonic phantom pass rate according to the number of years of use of ultrasonic equipment in Gwangju, this study derived that the service life of ultrasonic equipment is related to the equipment performance. As the coverage for ultrasonic inspection is gradually expanded starting with the upper abdominal ultrasound, it is time to further manage the quality of ultrasonic inspection. Therefore, in addition to the standard guidelines for performance measurement for abdominal inspection, research on equipment phantom measurement methods and standards that can be used in various ultrasonic inspection areas such as the neck and chest, which have recently become increasingly important in clinical practice, should be conducted at the same time. In addition, quality control standards should be legally established to maintain the optimal performance of ultrasonic imaging devices and to secure the appropriateness of images. In addition, ultrasound imaging devices should be classified as special medical equipment, and it is considered that the level of equipment should be consistently maintained through continuous management so that images beneficial to treatment can be obtained.

The tolerance of Korean benthic macroinvertebrates to organic pollution has been analyzed since the early 1990s. However, considering the fact that there have been related studies carried out in some European countries since the early 20th century, the history of the research in Korea is very short and there is still much knowledge to supplement. We revised the saprobic valency, the saprobic value and the indicator weight value of 190 benthic macroinvertebrates taxa through the data of water quality and individual abundance collected from 7,086 sampling units in Korea from 2008 to 2014. The individual abundance of Uracanthella (Ephemeroptera) as a representative, one of the most common and abundant taxa in Korea, showed a typical lognormal distribution to 5-day biochemical oxygen demand (BOD5) concentration, and a normal distribution to the class interval of BOD5 concentration according to saprobic series. The value combining the mean individual abundance and the relative frequency of occurrence was a more efficient indicator value than that of each property alone. Benthic Macroinertebrates Index (BMI) was newly proposed as a modification of the saprobic index of Zelinka and Marvan (1961). BMI showed extremely significant correlation (determination coefficient $r^2$ > 0.6, n = 569 sites) with the concentration of BOD5, and the coefficient was a little higher than those of the previous indices. Until now, there has been very little research on the assessment of biological integrity of benthic macroinvertebrates community in Korea. While continuing researches into improve the reliability of BMI, it is necessary to develop multimetric indices for evaluating the integrity, including the composition of species and functional guilds, and the richness and diversity of the community.
