Objectives: This community-based cohort study was performed to investigate the incidence of and factors related to self-reported fragility fractures among middle-aged and elderly women living in rural Korea. Methods: The osteoporosis cohort recruited 430 women 40 to 69 years old in 1999, and 396 of these women were followed over 11 years. In 1999, questionnaires from all participants assessed general characteristics, medical history, lifestyle, menstrual and reproductive characteristics, and bone mineral density. In 2010, self-reported fractures and the date, site, and cause of these fractures were recorded. Cox proportional hazards models were used to calculate hazard ratios (HRs). Results: Seventy-six participants among 3949.7 person-years experienced fragility fractures during the 11-year follow-up. The incidence of fragility fractures was 1924.2 per 100 000 person-years (95% confidence interval [CI], 1491.6 to 2356.8). In the multivariate model, low body mass index (HR, 2.66; 95% CI, 1.13 to 6.24), a parental history of osteoporosis (HR, 2.03; 95% CI, 1.18 to 3.49), and postmenopausal status (HR, 3.50; 95% CI, 1.05 to 11.67) were significantly related to fragility fracture. Conclusions: Fracture prevention programs are needed among postmenopausal, rural, Korean women with a low body mass index and parental history of osteoporosis Korea.

Hydrofluoric acid is one of the strongest irritating, corrosive and poisonous inorganic chemicals. Hydrofluoric acid burns are occurring with ever-increasing frequency due to the wide use of this acid in industries. Hydrofluoric acid burns are characterized by severe progressive tissue destruction and excruciating pain due to the unique properties of the freely dissolvable fluoride ion. The authors reviewed medical records of 32 cases (36 spells) of hydrofluoric acid burns which occurred in a hydrofluoric acid manufacturing factory from Sep. 1, 1990 to June 30, 1993. The results are as follows; 1. Eleven measurements of air concentrations of hydrofluoric acid by detection tube method from 1990 to 1992 were all below TLV (Department of Labor, R.O. K). 2. There were 19 cases (22 spells) of hydrofluoric acid burns which occurred during the study period among regular employees. The overall incidence density of hydrofluoric acid was 17.8 cases (20.6 spells) per 100 person-year. Incidence density was 19.0 cases (22.0 spells) per 100 person-year among male workers and there were no female cases. Incidence density was 32.9 cases (38.3 spells) per 100 person-year among production workers and 1.9 cases (1.9 spells) per 100 person-years among management workers with the difference being statistically significant (P<0.01). 3. Of 32 cases (36 spells) of hydrofluoric acid burns among workers who were regularly employed or temporarily employed, 26 spells (81.2%) were between age 20 to 39. In 15 spells(41.7%) burns occurred between 12:00 and 17:59 with 16 spells(44.3%) having arrived at hospital within 2 hours after the accident. 4. Of 36 spells, the main cause of hydrofluoric acid burns were by splashes (8 spells, 22.2 %). The most frequent site of burns were fingers and pain was the most frequent symptom. Thirty spells (83.3%) of the hydrofluoric acid burns were treated with local injection of antidote (calcium gluconate). Complete recovery without scarring were observed in most of the cases (34 out of 36 cases, 94.4%). The study results suggest that to prevent hydrofluoric acid burns, environmental control and the wearing of hydrofluoric acid resistant protective clothes and gloves are important. It is also stressed that establishment of an emergency management and a transfer system for hydrofluoric acid burn victims is necessary.

Objectives: This retrospective cohort study aimed to estimate the mean sojourn time (MST) of preclinical gastric cancer in Korean men. Methods: The subjects consisted of voluntary male screenees aged 40 to 69 years who underwent subsequent screening gastroscopies after testing negative at a baseline screening performed between January 2007 and December 2011. A new case was defined if gastric cancer cells were present in the biopsy specimens obtained from gastroscopy. The follow-up period was calculated as the number of person-years between the date of baseline screening gastroscopy and positive findings at a subsequent screening. The MST was calculated using transition rates of gastric cancer to determine the best screening interval. Results: Of the 171 979 voluntary male screenees, 61 688 (36%) underwent subsequent screening gastroscopies between January 2007 and December 2011. A total of 91 incident cases were found during 19 598 598 person-years of follow-up. The MST of gastric cancer was 2.37 years (95% confidence intervals, 1.92 to 2.96), and those aged 40 to 49 years had a shorter MST than those 50 to 69 years did. Conclusions: These findings support the 2-year interval of screening recommended by the nationwide gastric cancer screening program in Korea. Further studies for the age-specific MST among women are needed.

Purpose: The purpose of this study is to find out the patterns of teenage girls who is easy to suffer from dysmenorrhea with the Inbody test results by Sasang constitutions. Methods: The data from the 1681 participants were collected using a structured menstrual history questionnaire. Based on the survey responses, we had 97 adolescents with menstrual disorder as the test group and 97 adolescents without menstrual disorder as the control group. The clinical trials subjects were asked to respond to another questionnaire for identifying their constitutional types and undergo Inbody test. Results: The result of a comparison of the test and control groups showed that there' no relevance to the body fat mass and body fat percentage with menstrual irregularities. The lesser yang person with menstrual irregularities was no relevance to the body fat percentage. The greater yin person with menstrual irregularities was especially lacking in body fat mass and body fat percentage. The lesser yin person with menstrual irregularities was poor in body fat mass. Conclusions: As for study, female high school students with menstrual disorders have nothing to do with muscle mass. Body fats shortage could pose problems. According to the study, Taeumin female high school students usually needed to higher body fat than a general standard. It seems to be needed more body fat and weight than modern standards in period of poor sexuality for having a normal menorrhea especially Taeumin. It will take some continuing study that BMI standards should be changed or not on the Sasang constitutions.

Through this literal study, we have endeavored to provide korea's unique nursing intervention methods based upon Lee Je-Ma's Sasang Constitutional Theory which is a unique korean medical science. The Sasang Constitution Theory lay great emphasis upon health caring medicine to promote health according to self Constitution at normal times, preventive medicine to manage byself body and mind in everyday life, and eventually, ethical medicine to love benevolence and kindness but to dislike jealousy.A variety of methods has been introduced to diagnose a person's Constitution. And yet, appearance, mind and pathological signs are three major criteria. In appearance, comprehensive features such as figure (the shape of the human body), countenance, behavior, mood, and posture are observed. In mind, nature (character), talent, steadiness, personality, and greed are investigated. In pathological signs, physiological conditions when healthy and peculiar symptoms when being ill are diagnosed. By these three criteria, each Constitution is categorised into Taiyang Person, Soyang Person, Taieum Person or Soeum Person. Different healthcaring methods exist for each Constitution such as mind and body healthcaring, diet healthcaring, knowledge and behaviour leathering, age group healthcaring, regional healthcaring, social life hralthcaring, everyday life healthcaring, and materia medication healthcaring. An independent and unique healthcaring method for each person according to self Constitution could be an important nursing intervention strategy, and can product a new nursing theory. To enjoy longevity by inducing positive caring methods, I believe that individual nursing may be the most desirable nursing approach. Lee Je-Ma's Sasang Constitution caring method is not only a general nursing theory but also expected to be an important landmark/milestone/factor in Korean nursing, preventive nursing, developing new nursing intervention methods and forming new nursing theories. Therefore, it is required to conduct thorough, practical and theoretical researches in the field of nursing.

Background: It is well known that skin cancer and precancerous disease develop more frequently in patients undergoing solid organ transplantation than normal populations in the normal population in Western countries. However, to date, the clinical and demographic features of skin cancer and precancerous disease after solid organ transplantation are not established in Asian countries. We evaluated the clinical and demographic features of primary skin cancer and precancerous lesions after solid organ transplantation and compared these with the trends observed in Western countries. Methods: We retrospectively reviewed the medical records of patients who underwent kidney, liver, heart, and lung transplantation between January 1995 and April 2017 and who developed skin cancer or precancerous lesions after transplantation. The various lesions observed were squamous and basal cell carcinoma, malignant melanoma, Kaposi sarcoma, Bowen's disease, and actinic keratosis. Results: We identified 4604 patients who received organ transplant. The mean age of patients was 44.8 years (male, 64.6%; female, 35.4%), and the sum of the person-year of observation time was 31,024 person-years. The incidence rate per 100,000 person-years was 29.01 for squamous cell carcinoma, 19.34 for basal cell carcinoma, 6.45 for malignant melanoma 3.22 for Kaposi sarcoma, and 74.17 for Bowen's disease and actinic keratosis. The incidence rate per 100,000 person-years was the highest in patients undergoing heart transplantation (610.50), followed by those who underwent kidney transplantation (136.54) and liver transplantation (90.15). Koreans showed lower incidence rates than those observed in Westerners. Conclusion: The incidence of primary skin cancer and precancerous lesions after solid organ transplantation in Koreans was lower than that in Westerners. Squamous cell carcinoma was the most common skin cancer in patients undergoing solid organ transplantation and the incidence rate of skin cancer and precancerous lesions was the highest in patients undergoing heart transplantation.

Objectives : The Annals of the Joseon Dynasty has plenty of articles as primary historical records. The Korean medical historiy researches have also been driven from The Annals of the Joseon Dynasty. About public services in Joseon dynasty related to medicine, We rarely know persons in public services, titles, levels and so on. Methods : I focused on The Annals of the Joseon Dynasty to research the titles of person in public services in early Joseon dynasty. I found 33 persons related to medicine and reorganized 21 persons who had titles. Results : I got 10 titles of public medical services and more than 15 titles of public non-medical services, which were received according to their medical services and 6 grades. Conclusions : I concluded that there were much more titles of public medical services than what we had already known and several titles and grades of public non-medical services, which were received according to their medical services.

In oriental medicine, human being is classified into four groups according to their body constitution status (;tae-yang, tae-eum, so-yang, and so-eum persons) considering the differences in function of internal organs and characteristics. Four body constitution, called 'sa-sang' has been recognized as an important factor for diagnosing the patients before madical teratment. Yet, the criteria to divide body constitutions or its scientific principle are not clearly defined. As an initial effort to elucidate biological priciples underlying four body constitution groups, we studied genetic variations among three constitution groups (tae-eum, so-yang, and so-eum persons). Noting distinct responses to ingested food and administered drugs among three groups, SNPs and haplotype experiments were performed in 2D6, 2C9, and 1A2 DNA regions of the cytochrome P450 gene. Significant variability in SNPs types was found in 2D6 region. Moreover, haplotyping in 2D6 region showed relatively high occurrences of haplotype 3 and 5 in so-eum person, haplotype 6 in tae-eum person, and hyplotype 1 in so-yang person. These results indicate that individuals with different body constitutions respond differently to ingested food and drugs, which might reflect constitution-specific genetic background. The genetic approach would therefore be useful to reveal intrinsic differences among four constitution body groups in the responsiveness to various drugs and external stimulations to human body.
