Purpose: To analyze the correlation between serum alanine aminotransferase (ALT) and obesity indices including body mass index (BMI), body fat percentage (BFP), total fat mass (FM), truncal fat mass (TFM), waist circumference (WC), and waist-to-height ratio (WHtR) in Korean adolescents. Methods: This was a cross-sectional study based on data derived from the 2010-2011 Korean National Health and Nutrition Examination Surveys (KNHANES). Subjects were Korean adolescents aged 10-18 years (871 total; 475 boys and 396 girls) who participated in KNHANES. Results: In both sexes, BMI, FM, TFM, WC, and WHtR were higher when ALT levels were in the 4th quartile. In boys, there was a significant positive correlation between ALT level and BMI, BFP, FM, TFM, WC, and WHtR (r=0.55, P<0.0001 for BMI; r=0.52, P<0.0001 for BFP; r=0.58, P<0.0001 for FM; r=0.61, P<0.0001 for TFM; and r=0.56, P<0.0001 for WC; r=0.62, P<0.0001 for WHtR), and the correlation coefficient was higher than that in girls. Conclusion: Our results suggest a significant positive association between serum ALT level and obesity indices in male adolescents.

According to the dietary surveys and national food balance sheets, the dietary state of person living in Korea is ingesting a high level of grain and vegetable diet and very low animal sources. The daily calory intake is about 2,300-2,600 Cal. per head in which a total protein intake is 69-86 gm respectively. These data indicate no shortage of calory and total protein intake. However, the intake of animal protein is only 4-11 gm and the fat is 8-18 gm, both of which are far below the requirment. The low fat intake brings about a low level of fat soluble vitamins, and that V-A intake is as short as the half amount of the allowance. Riboflavine is also about a half of dietary requirment. Both thiamin and ascorbic acid intake are sufficient. The calcium intake is 0.26-0.5 gm per day which is inadequate. In fact, biochemical findings through field survey show; serum protein 6.7 gm, hemoglobin 13.1 gm and hematocrite 41.5% all of which are lower than the Kwon's report. The serum V-A and uunrinary riboflavin value are also lower than the Williams'es report. Clinically, inflamation of the eyes, cheilosis, pathological signs of tangue, xerosis of the hand and arm, or the like are frequently seen. On the other hand, there is no suitable diet available for the weaning infant and delayed weaning is a common practice. A school lunch program is still in an early stage of development. Another example can be cited that the Korean infant grows faster than the Japanese until one year of age, and no difference is noted between the Korean and the American infants up to six monthes of age, thereafter the former lags in the growth rate. This might be mainly due to the nutritional reasons as mentioned above, and in part due to the high inidence of intestinal parasitism and others.

제주특별자치도는 2005년 1월 27일 정부로부터 세계평화의 섬으로 지정을 받았고, 2007년 7월 세계보건기구(WHO)에서 안전도시로 인증을 받았다. 최근 몇 년 동안 제주에서 발생한 각종 산업재해를 보면, 세계평화의 섬과 국제안전도시와는 어울리지 않는 안전사고가 많이 발생하고 있다. 특히 건설현장에서는 미숙련자가 늘어나면서 후진국형의 안전사고는 계속해서 발생하고 있다. 더불어 제주 지역의 건설현장은 다른 지방과 지역적으로 분리되어 있어서 일정 수준의 근로자를 채용하기가 어렵다. 이로 인하여 건설현장의 안전사고의 위험이 높은 편이라고 할 수 있다. 본 연구에서는 제주지역 건설현장의 안전관리 수준과 사고발생시 응급처치 현황 등에 대한 실태조사를 실시하여 개선방안을 제시하였다.

Recently, the pop-up satellite archival tag (PSAT) is being used in studies as a method of using satellites for monitoring organisms. Because PSATs are attached directly on the organism being monitored, it is used mostly on larger species since the health of the organism is an important concern. For this reason, PSAT-based surveys are lacking in Korea with no studies on the physiological responses of organisms with PSAT attached. Accordingly, as a basic biomonitoring study using PSAT, the present study investigated the physiological changes in fish in response to the attachment of PSAT. The present study used red seabream (Pagrus major) and Korean rockfish (Sebastes schlegelii) as the experimental fish. The PSAT was attached to the muscle below the experimental fish's dorsal fin using a mono filament (n = 3). To investigate the changes in physiological responses according to PSAT attachment, blood samples were collected from all experimental fish, including the control (n = 3), at 1, 7, 14 and 21 days after the attachment. Upon blood sample collection, whole blood was used to measure hematocrit and hemoglobin levels. After separating the plasma, the separated plasma was used to measure the GOT, GPT, glucose, total protein, and cholesterol levels. Meanwhile, the plasma cortisol, superoxide dismutase, and catalase levels were measured using the ELISA method. The results showed that attaching the tag did not have any impact on the immunity and stress response of the experimental fish. The findings in this study also demonstrated the possibility of using PSAT for studying relatively smaller species living in the coastal waters of Korea.

The object of this study was to examine attitudes and knowledge of Korean dieticians about functional foods. We investigated their perceived knowledge and their attitudes regarding risks versus benefits, and recommendation about the use of functional foods; as well as their frequency of personal use, and the educational supports and training needs of dieticians. We developed a questionnaire to assess the dieticians' attitudes related to functional foods. This questionnaire was used for characterizing functional food-related attitudes on the basis of factor and reliability analysis in the following study. The questionnaires were distributed to 802 practicing dieticians working in Daegu and Gyeongsangbukdo. A total of 244 respondents (mean age $34\pm5.7$ years) returned the completed questionnaires through online surveys. Descriptive statistics and ANOV A were used to analyze data. Fewer than $2\%$ of dieticians claimed themselves to be knowledgeable about functional foods, more than $79\%$ consumed functional foods more than once a week, and $88\%$ of dieticians expressed an interest in receiving training about functional foods. Dieticians had favorable attitudes about the rewards from functional foods but were not confident about the safety and usage recommedation of these foods. The level of knowledge and educational support at their universities about functional foods affected the dieticians' attitudes regarding the rewards from and recommendation about the use of functional foods. These results suggest a need for additional educational opportunities to facilitate a better understanding of the risks and benefits of functional foods and their proper usage. Dietetics professionals must adapt to changes in health practices through effective educational programs integrating sufficient knowledge about functional foods.

Objectives: The purpose of this study was to evaluate the effect of nutrition education using materials based on social cognitive theory. Education topics focused on improving health-related and dietary self-awareness and behavior capability in adolescents. Methods: Participants were recruited from a middle school for girls; 67 students (educated group, n=34 and control group, n=33) participated. The education group received 12 lessons in club activity class. Self-administered surveys were conducted for each group before and after the nutrition education program. The questionnaires consisted of variables such as self-efficacy, outcome expectation, outcome expectancy, knowledge, and dietary practices based on the social cognitive theory. Education satisfaction was evaluated using a five-point Likert scale for two sections: a) teaching and learning and b) education results. The data were analyzed using a t-test and Chi Square-test (significance level: p < 0.05). Results: In the education group, post-education, there were significant differences in self-efficacy (p < 0.05), knowledge (p < 0.01), and dietary practices (p < 0.05), whereas outcome expectation and expectancy did not show any significant differences. None of the variables showed any significant differences in the control group. Educational satisfaction scores were $4.38{\pm}0.12$ (teaching and learning) and $4.14{\pm}0.15$ (education results). Conclusions: This study showed that improving adolescent's awareness and behavior capability has a positive effect on their dietary practices. Moreover, this study suggested that a theory-based determinant should be considered to improve dietary behavior among adolescents.

Monthly surveys were conducted to investigate the occurrence of chigger mites and seroprevalence of scrub typhus among small mammals in Jeollanam-do, the southwestern part of Korea, from November 2006 through October 2007. Fifty-eight small mammals, including 57 Apodemus agrarius (98.3%) and 1 Crocidura lasiura (1.7%), were captured, and a total of 4,675 chigger mites representing 4 genera and 8 species were collected from them. The chigger infestation rate among small mammals was 69.0%. The most predominant species in A. agrarius was Leptotrombidium scutellare (54.0%), followed by Leptotrombidium pallidum (39.4%), Leptotrombidium orientale (4.4%), Leptotrombidium palpale (1.1%), Neotrombicula tamiyai (0.6%), Eushoengastia koreaensis (0.3%), Neotrombicula gardellai (0.3%), and Cheladonta ikaoensis (<0.1%). The chigger index of A. agrarius was the highest in October (740.0), followed by November (242.0), September (134.6), March (98.3), February (38.2), January (35.3), December (34.5), April (30.8), and May (1.7). The average antibody positive rate of scrub typhus in wild rodents was 50.0%. The seropositive rates were high in October (100.0%) and November (83.3%), whereas those in other months were relatively low (28.6-57.1%). The chigger index of L. scutellare rapidly increased in September to form an acuminate peak in October, followed by a gradual decline. These results suggest that the outbreak of scrub typhus in the southwestern part of Korean peninsula is mostly due to L. scutellare.

Objectives : The purposes of this study is to estimate the cost of cancer care after its diagnosis and to identify factors that can influence the cost of cancer care. Methods : The study subjects were patients with an initial diagnosis one of four selected tumors and had their first two-years of cancer care at a national cancer center. The data were obtained from medical records and patient surveys. We classified cancer care costs into medical and nonmedical costs, and each cost was analyzed for burden type, medical service, and cancer stage according to cancer types. Factors affecting cancer care costs for the initial phase included demographic variables, socioeconomic status and clinical variables. Results : Cancer care costs for the initial year following diagnosis were higher than the costs for the following successive year after diagnosis. Lung cancer (25,648,000 won) had higher costs than the other three cancer types. Of the total costs, patent burden was more than 50% and medical costs accounted for more than 60%. Inpatient costs accounted for more than 60% of the medical costs for stomach and liver cancer in the initial phase. Care for latestage cancer was more expensive than care for early-stage cancer. Nonmedical costs were estimated to be between 4,500,000 to 6,000,000 won with expenses for the caregiver being the highest. The factors affecting cancer care costs were treatment type and cancer stage. Conclusions : The cancer care costs after diagnosis are substantial and vary by cancer site, cancer stage and treatment type. It is useful for policy makers and researchers to identify tumor-specific medical and nonmedical costs. The effort to reduce cancer costs and early detection for cancer can reduce the burden to society and improve quality of life for the cancer patients.

Objectives : This study was conducted to identify awareness and satisfaction of herbal medicine preparations in Korean medicine doctor(KMD). Methods : The questionnaire consisted of three professors of Korean medicine based on previous researches and reports. The pilot survey was conducted to five KMDs who work in local clinic to get face validity. Based on the results of the pilot survey, three professors of Korean medicine completed the final version. Online surveys was conducted to member of the association of Korean medicine from march 25 to april 6 in 2016. Results : The proportion of patients who prescribe herbal medicine was not significantly correlated to gender (p=0.346), but significantly correlated to age(p<0.01), specialty(p=0.017), monthly income(0.022), and clinical experience(p<0.001). The most common reason for using the herbal preparations which is covered by NHI (National Health Insurance) was due to patient's payment(39.3%). Likewise, the most common reason for using the herbal preparations which is not covered by NHI was various kind of prescription(34.1%). Conclusions : The utilization of herbal preparations could be enhanced by expansion of NHI cover range of herbal preparations.
