Human taeniasis was investigated in Lao People's Democratic Republic (Lao PDR) between 2000 and 2011 as part of the nation's helminthiasis survey. A total of 55,038 inhabitants, including 29,846 school children, were examined using the Kato-Katz and scotch-tape anal swab method, and morphological observation of adult worms. Molecular identification of Taenia tapeworms was performed by multiplex PCR or DNA sequence analysis of the mitochondrial cox1 gene. Taenia eggs were present at a rate of 1.5% (845/55,038) in the subject population. Adult tapeworms were identified as T. solium or T. saginata by analyzing the collectable stool specimens (n=126). Three specimens identified as T. solium were found in Luang Prabang, while the remaining 123 specimens, which were T. saginata, were found in Bokeo, Bolikhamxay, Champasak, Houaphan, Khammouane, Luang Namta, Luang Prabang, Oudomxay, Phongsaly, Saysomboune, Saravane, Savannakhet, Xayaboury, Xekong, Xieng Khouang Province, and Vientiane Municipality.

The taxonomy of Spirometra species has been controversial despite the medical and veterinary importance. Currently, only a few Spirometra species are considered valid species in the genus Spirometra. In the present study, the distribution of Spirometra species obtained from animals in Korea were identified by molecular analysis of the mitochondrial cytochrome c oxidase I (cox1) gene. A total of 28 Spirometra species specimens were analyzed. These were all collected between 1973 and 2008 in the Republic of Korea. Mitochondrial cox1 sequences were examined for a total of 28 specimens comprising 14 S. decipiens and 14 S. ranarum. The difference in partial cox1 sequences (316 bp) between S. erinaceieuropaei (KJ599680) and S. ranarum (this study) was 9.3%, while that between S. decipiens (KJ599679) and S. ranarum (this study) was 2.2%. Genetic analyses identified 2 Spirometra species in animals such as cat, leopard cat, dog, duck and snake in Korea as S. decipiens and S. ranarum. S. decipiens and S. ranarum were present in Gyeongnam Province (P), Jeonnam P, Gangwon P, Chungbuk P, and Seoul. S. decipiens was found in tadpoles, snakes, ducks, cats, leopard cats and dogs, while S. ranarum was found in cats and dogs. The ratio of S. decipiens:S. ranarum calculated from the molecular data was 14:14 (or 1:1). These results indicate that S. decipiens and S. ranarum are sympatrically distributed in Korea.

Objective : To investigate the sources, extent and related factors in South Korean doctors. Methods : The study subjects were 934 doctors in Taegu, Kyungpook Province, Korea(540 independent practitioners, 105 employed at hospitals and 289 residents in training). Information concerning job stress was obtained using a 9-item questionnaire. Information regarding related factors such as demographic characteristics(age, sex, marital status), perceptions on the socioeconomic status of doctors and working conditions(work time, on-call days per week) was also obtained by self-administered questionnaire during April and May, 2000. Results : Major sources of job stress included clnical responsibility/judgement factor, patient factor and work loading factor. The job stress score of residents was the highest among three groups. The score was lower in older doctors. The score was low among those who thought doctors' socioeconomic status was not good. The longer the work time, the higher the job stress score was. Multiple regression analysis was conducted to control for the mutual influence of independent variables. In regression analysis, the score of residents was higher than practitioners. Work time and socioeconomic status perception had negative effects on job stress score. Conclusion : The average job stress score of the doctors was high. Age, work type, working conditions and perceptions of socioeconomic status were found to besignificantly related to job stress score. Although the job stress of doctors is somewhat inevitable due to the nature of the doctor's job, control of work time, development of coping tools and other intervention methods are needed to reduce job stress of doctors. Further studies are required to understand the characteristics of iob stress and reduce the job stress of doctors.

Filefish Thamnaconus modestus has seen a sharp decline in their catch, we must strive for continuous resource management. We investigated the maturation and spawning of T. modestus by trawl net and set net from January 2018 to November 2019, off Jeju Is. and in coastal waters of North Gyeongsang Province's Korea. We analyzed monthly change total length (cm), gonadosomatic index (GSI) and maturity stages, egg diameter (mm), the relations fecundity and total length. GSI for Jeju Is. was the highest in April (3.17, 2.43), and decreased from July to 1.73 in August and GyeongBuk's GSI was the highest in Apri l (1.86, 2.58), followed by the high in May and the sharp decline in September, which is 0.23. Using a histological method, the annual reproductive cycle of T. modestus can be divided into 5stage in females; the early growing stage (Jan.-Mar.), late growing stage (Apr.-May), Mature stage, spent stage (Oct.), Recover and resting stage (Nov.-Jan.).We estimate the TL at 50% maturity as 24.1cm for female, fecundity ranged from 560,044 eggs at 23.4cm total length to 1,580,387 eggs at 36.6.cm TL.

The purpose of this study is to verify the relation between vegetarian diet and the risk factors of cardiovascular disease. To do the present study the vegetarians were selected;245 Buddhist nuns(age: 23-79yrs). For control subjects, 235 healthy female adults(age: 23-79yrs) were selected. They were the teachers, the nurses and the housekeepers living in Chinju Gyeongsang Namdoo Province. Study period was from October 1996 to February 1997. The contents are consist of survey, anthropometric measurement, and clinical examination. The average ages of the subjects were 44.20yrs for vegetarians and 40.52yrs for non-vegetarians respectively. Average body mass indice(BMI) of vegetarians and non-vegetarians were 22.47 and 21.08, WHR was 0.85 and 0.84, percentage of body fat was 28.79 and 26.55 and the average duration of vegetarian diet of the vegetarians was 13.16 years. On the nutrient related lipid, fat, the energy ratio of fat, saturated fatty acid, total fatty acid, monounsaturated fatty acid and total-cholesterol were significantly lower(p<0.01) but the ratio of p/s was significantly higher(p<0.01) in vegetarians than non-vegetarians. The vegetarians were significantly higher than the non-vegetarians in intake of fiber, vitamin C. In vegetarians, variables that significant negative correlation with fiber were total-cholesterol, AI, blood sugar. In non-vegetarians, variables that significant negative correlation with fiber were TG, total-cholesterol, blood sugar, systolic blood pressure. In both subjects, the serum lipid concentration and the blood pressure were getting lower with fiber intakes. Consequently, vegetable diet can be considerably effective in making the level of the risk factors causing in cardiovascular disease lower. (Korean J Nutrition 34(3) : 313∼321, 2001)

This article looks into Lee Gyujun(李圭晙)'s life course, Confucian thoughts, and philosophical ideas on the Medicine of Boosting Yang by translating selectively his "Seokgoksango(石谷散稿)". Translating his works is a pre-requisite in order to fully understand the significance of boosting-yang theory in the historical landscape of Korean medicine, not just to comprehend the Medicine of Boosting Yang. First, it is found through the translation that a previous version of "Seokgoksango" had been probably printed before its existing version 1981. Secondly, there are numerous resistants to the Japanese ruling of Korea among his friendship. Thirdly, his academical root came from the Gihohakpa(畿湖學派) - the Giho school of Korean Seongli Confucianism[朝鮮性理學]. Its genealogy in Gyeongsang(慶尙) province is as follows: Lee Yi(李珥), Song Siyeol(宋時烈), Hong Jikpil(洪直弼), Seo Changyu(徐贊奎) and Lee Gyujun(李圭晙), and last, he kept contact with the Toegyehakpa(退溪學派), the Toegye school of Korean Seongli Confucianism, even though his academic root was closely linked to the Giho school. If the entire parts of "Seokgoksango" is translated, it will serve as invaluable historical document to understand a medical unfolding around the 20th century in Korea.
