Daegu (the city in South Korea) who visited a medical institution for medical checkup in 2016. The urine cotinine test strip (DCT-102; CLIAwaived Inc., cut-off value = 200 ng/mL) was used to classify the actual smoking status and to assess the validity of self-reported smoking status on questionnaires. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the smoking questionnaires were analyzed. Subjects testing positive in the urine cotinine test (assumed the actual current smokers) were selected. The frequency at which actual current smokers were misclassified as current non-smokers by the questionnaire was calculated. Subjects' characteristics were analyzed for possible association with any discrepancy between self-reported smoking status and urine cotinine test results.RESULTS: The smoking rates among firefighters surveyed using the smoking questionnaire and the urine cotinine test were 22.47% and 51.24%, respectively. Of the all subjects, 29.66% (n = 132) were misclassified. The sensitivity of the smoking questionnaire was 42.98%, the specificity was 99.08%, the PPV was 98.00%, and the NPV was 62.32%. In the 228 subjects classified as current actual smokers by the urine cotinine test, 57.02% (n = 130) were misclassified on the questionnaire. The misclassification rate increased with age. The degree of misclassification also increased when subjects had a history of disease.CONCLUSIONS: In present study, the validity of the smoking questionnaire for firefighters was not suitable for investigating smoking status due to low sensitivity. To increase the validity of smoking status monitoring in firefighters, consideration of the various factors like survey environment, subjects' characteristics, and occupational factors is needed.]]>

2.Comparison of Salinity and Sodium Content by the Salinity Measurement Frequency of Soups of Childcare Centers Enrolled in the Center for Children's Food Service Management in Daegu
Korean Journal of Community Nutrition 2020;25(1):13-20
OBJECTIVES: This study examined the salinity of soups provided at childcare centers by measuring the salinity for three years and providing basic data for sodium reduction.METHODS: The soup salinity was measured using a Bluetooth salinity meter from January 2015 to December 2017 at 80 childcare foodservice establishments enrolled in the Suseong Center for Children's Foodservice Management in Daegu.RESULTS: An analysis of the soup salinity each year showed that the salinity decreased significantly from 0.48% in 2015 to 0.41% in 2017, particularly in clear soups and soybean soups compared to other soups (P < 0.05). The salinity and sodium content in seafood soups (0.45% and 179.1 mg/100 g, respectively) were highest, followed by soybean soups (0.44%, 175.2 mg/100 g), with perilla seed soups containing the lowest (0.42%, 167.2 mg/100 g) (P < 0.05). The salinity was significantly higher in institutional foodservice establishments than small foodservice establishments (P < 0.001). The salinity and sodium content were the highest in foodservice establishments with a small number of measurements, and the salinity was the lowest in foodservice establishments with salinity measurements performed an average of 151 times each year (three times a week) or more (P < 0.05). The soup salinity was low in the order of winter, spring, summer, and autumn, and the salinity decreased significantly year by year in all seasons. (P < 0.05).CONCLUSIONS: The soup salinity was significantly lower in foodservice establishments where the salinity was measured more than three times a week, indicating that continuous salinity management is effective.

BACKGROUND/AIMS: School nurses’ knowledge of inflammatory bowel disease (IBD) has not been evaluated. We aimed to investigate school nurses’ knowledge of IBD and determine whether education could improve this knowledge. METHODS: School nurses were invited to complete self-reported questionnaires on IBD. Then, IBD specialists from tertiary referral hospitals provided a 60-minute lecture with educational brochures on two occasions, with a 3-month interval. Within 6 months after the educational interventions, school nurses were asked to complete the same IBD questionnaire via e-mail. RESULTS: Among 101 school nurses who were invited to participate, 54 nurses (53.5%) who completed two consecutive questionnaires were included in this study (median age, 45 years; range, 25 to 59 years; 100% female); 11.1% and 7.4% of the study participants had no knowledge regarding ulcerative colitis and Crohn’s disease, respectively. They had heard of IBD most frequently from doctors (33.3%), followed by internet sources (25.9%). After 6 months, the number of nurses who could explain IBD to students with over 30% confidence increased from 24 (44.5%) to 42 (77.8%) (p < 0.001). Most nurses (81.5%) reported that the educational intervention was helpful for managing students with abdominal pain or diarrhea. The number of students who received IBD-related welfare services from the Daegu Metropolitan Office of Education doubled when compared with the corresponding number during the prior educational year. CONCLUSIONS: There is room for improvement in school nurses’ knowledge of IBD. A systematic educational program on IBD should be implemented for these nurses.

OBJECTIVE: The mismatch in the demand and supply of emergency medical resources has been a constant issue in Korean emergency departments (EDs). This study analyzed the characteristics and actual utilization of medical bed resources in these EDs. METHODS: The emergency department utilization (EDU) rate was calculated using the Emergency Medical Resource Information System (EMRIS) on the available beds in EDs from April 2014 to January 2015. The EDU rate was analyzed according to the season, day of the week, time of day, and ED type. Furthermore, the ratio between the maximum and minimum EDU rates was also compared between the regions. RESULTS: A total of 14,889,750 data points were included. The EDU rate was relatively high during winter and on Sundays, and was highest between 20:00 and 22:00. The ratio between the maximum and minimum EDU rates according to the time of day was highest in Gyeongbuk (5.4) and lowest in Daegu (1.4). Moreover, the EDU rate according to the ED type was highest in the regional emergency medical center (66.7%). CONCLUSION: Significant differences were observed in the EDU rates according to the season, day of the week, time of the day, region, and ED type. Therefore, EMRIS should allocate resources based on the data on both the hospital and regional characteristics.

5.Analysis of the Prescription Patterns of Medications that List Suicide in Use Cautions using the HIRA Claims Data
Korean Journal of Clinical Pharmacy 2019;29(3):202-208
OBJECTIVE: Suicide has recently become an important social problem. Thus, we analyzed prescription drugs that cause suicidal ideation. METHODS: Of 156 drugs on the the Minister of Food and Drug Safty (MFDS) EZ-Drug site that had “suicide” listed as a side effect, 78 had “suicide” listed as a warning or contraindication; those 78 drugs were analyzed using data from the 2016 Health Insurance and Review and Assessment Services National Patient Sample (HIRA-NPS). RESULTS: 51 “suicide risk” drugs was identified. Of all patients, 5.2% had received such drugs. The prescription rate was 0.8% of all prescriptions, accounting for 1.6% of all prescription days. From logistic regression analysis, the prescription rate for the drugs was approximately 1.1 times higher for women than for men. With regard to age, the prescription rate for patients 66 years and older was 15.5 times higher than those for patients 25-years and lower. With regard to medical departments, the prescription rates in psychiatry and dermatology departments were 8.1 times higher and 0.6 times lower than those in internal medicine departments, respectively. With regard to region, the prescription rates in Daegu and Jeju were 1.3 times higher and 0.79 times lower than those in Seoul, respectively. CONCLUSION: Drug-induced suicidal behavior is possible, and therefore efforts are needed to prevent it.

6.Death and Survival of Patients with Hansen's Disease in Colonial Korea
Korean Journal of Medical History 2019;28(2):469-508
The purpose of this research is to describe how Hansen's disease patients experienced the modern system of control of Hansen's disease introduced by Japan, and the inimical attitude of society against them in colonial Korea. The study also seeks to reveal the development of the system to eliminate Hansen's disease patients from their home and community to larger society and leprosarium in this era. Sorokdo Charity hospital (SCH), a hospital for Hansen's disease patients, was built in 1916, and vagrant Hansen's disease patients began to be isolated in this hospital beginning in 1917 by the Japanese Government-General of Korea (JGGK). Once the police detained and sent vagrant Hansen's disease patients to SCH, stigma and discrimination against them strengthened in Korean society. Because of strong stigma and discrimination in Korean society, Hansen's disease patients suffered from daily threats of death. First, their family members were not only afraid of the contagiousness of Hansen's disease but also the stigma and discrimination against themselves by community members. If a family had a Hansen's disease patient, the rest of community members would discriminate against the entire family. Furthermore, because Hansen's disease patients were excluded from any economic livelihood such as getting a job, the existence of the patients was a big burden for their families. Therefore, many patients left their homes and began their vagrancy. The patients who could not leave their homes committed suicide or were killed by their family members. The victims of such deaths were usually women, who were at the lower position in the family hierarchy. In the strong Confucian society in Korea, more female patients were killed by themselves than male patients. Moreover, all of patients victims in the murder were women. This shows that the stigma and discrimination against Hansen's disease patients within their families were stronger against women than men. Strong stigma and discrimination made the patients rely on superstition such as cannibalism. Patients believed that there were not any effective medicine. There were a few reports of patients who were cured, and many were treated with chaulmoogra oil in the modern Hansen's disease hospitals. Eating human flesh was known as a folk remedy for Hansen's disease. As such, patients began to kill healthy people, usually children, to eat their flesh. Increased stigma led to increased victims. Hansen's disease patients who left their homes faced many threats during their vagrancy. For survival, they established their own organizations in the late 1920's. The patients who were rejected to be hospitalized in the Western Hansen's disease hospital at Busan, Daegu, and Yeosu organized self-help organizations. The purpose of these organizations was first to secure the medicine supply of chaulmoogra oil. However, as stigma and discrimination strengthened, these organizations formed by Hansen's disease patients demanded the Japanese Government-General of Korea to send and segregate them on Sorok island. They did not know the situation of the inside of this island because news media described it as a haven for patients, and very few patients were discharged from this island to tell the truth. On this island, several hundreds of patients were killed by compulsory heavy labor, starvation, and violence. They were not treated as patients, but as something to be eliminated. Under strong suppression on this island, the patients resisted first by escaping this island. However, in 1937, some patients tried to kill a Korean staff but failed. Attempted murderers were all put in the jail, also located on this island. In 1941, a patient murdered another patient who had harassed other patients, and in 1942, Chunsang Lee, a patient, killed the director of Sorok island. These instances show that there was a system to eliminate Hansen's disease patients in colonial Korea.

7.Traditional Medicine Doctor Kim Gwangjin's Battle against Jaundice during the Japanese Colonial Period
Korean Journal of Medical History 2019;28(2):427-468
This study aims to examine how traditional medicine doctors (醫生) of the Japanese colonial period in Korea treated patients and their own diseases with traditional medicine (漢方) and Western medicine (洋方) by analyzing Clinical Cases (治案) and A Diary of Jaundice Treatment (治疸日記) of Kim Gwangjin (金光鎭, 1885–1940). Through this inquiry, this study aims to reveal that the Japanese colonial period was a time when the traditional medicine and the Western medicine coexisted, and that this period cannot be simply defined as a dualism between “Western medicine, Japanese colonial government” versus “traditional medicine, governed public.” Kim Gwangjin's main method of medical treatment was traditional medicine. Clinical Cases include over 60 treatment cases, and they illustrate that he was a typical doctor at the time using traditional medical knowledge. In addition, Kim wrote A Diary of Jaundice Treatment from January 1939 to July 1940, a month before his death. The disease that led to his death was jaundice. He examined the changes in his abdomen every day, and recorded the changes in edema in upper extremities and testicles, urine and feces. While the treatment that Kim used in the early stages of jaundice were herbal medicines, he was not confined to the boundaries of the traditional medicine as he studied Western medicine to obtain a license of traditional medicine doctor from Japanese colonial government. He took a urine test to confirm whether his illness was jaundice or kidney disease and had X-ray imaging to check for pleurisy at a Western medical hospital in Daegu. Furthermore, he received a procedure to artificially drain bile, took a medicine to excrete bile into the feces, and had injection to treat neuralgia. Mostly, it was diarrhea that bothered Kim, who had been suffering from jaundice. Preventing diarrhea led to edema, and removing edema led to diarrhea again. He managed his symptoms by stopping the herbal medicine treatments and going on a raw food diet. Around this time, Kim relied the most on Ejisan (エヂ散). Ejisan was a type of new medicine mixed with traditional medicine and Western medicine that had the effect of treating edema and digestive disorders. Kim personally manufactured and took the drug until a month before his death, praising it as a necessary drug to treat jaundice. Kim was a traditional medical doctor during the Japanese colonial period. He also had the conventional wisdom that Western medicine was excellent in treating surgical diseases but not effective in internal medicine. However, he used both traditional medicine and Western medicine to treat symptoms of jaundice that have not been treated well and created a new medicine called Ejisan, which combined the two types of medicines. For him, Western medicine was a new medicine that improved the wrong aspects of traditional medicine or the old medicine, but there was still a realm of traditional medicine that Western medicine could not intervene. Furthermore, he published a new theory of traditional medicine called the Principle of Up and Down (升降論), which incorporates some Western medical knowledge. The Japanese colonial government required traditional medicine doctors to study Western medicine, and traditional medicine doctors had to learn Western medicine in order to survive. In the meantime, traditional medicine doctors such as Kim have brought about new changes by integrating the two medical treatments in the clinical field. The Japanese colonial government planned the demise of traditional medicine by forcing traditional medicine doctors to study the Western medicine, but the unexpected achievement brought about by traditional medicine doctors, who survived longer than the Japanese Empire and the colonial government, was an attempt to integrate Eastern and Western medicine.

Korean Journal of Psychosomatic Medicine 2019;27(1):42-49
OBJECTIVES: Living donor liver transplantation (LDLT) is a life-saving therapy for patients with terminal liver disease. Many studies have focused on recipients rather than donors. The aim of this study was to assess the emotional status and personality characteristics of LDLT donors. METHODS: We evaluated 218 subjects (126 male, 92 female) who visited Daegu Catholic University Medical Center from August 2012 to July 2018. A retrospective review of their preoperative psychological evaluation was done. We investigated epidemiological data and the Minnesota Multiphasic Personality Inventory-2 questionnaire. Subanalysis was done depending on whether subjects actually underwent surgery, relationship with the recipient, and their gender. RESULTS: Mean age of subjects was 32.19±10.91 years. 187 subjects received LDLT surgery (actual donors) while 31 subjects didn't (potential donors). Donor-recipient relationship included husband-wife, parent-children, brother-sister etc. Subjects had statistical significance on validity scale L, F, K and all clinical scales compared to the control group. Potential donors had significant difference in F(b), F(p), K, S, Pa, AGGR, PSYC, DISC and NEGE scales compared to actual donors. F, D and NEGE scales were found to be predictive for actual donation. Subanalysis on donor-recipient relationship and gender also showed significant difference in certain scales. CONCLUSIONS: Under-reporting of psychological problems should be considered when evaluating living-liver donors. Information about the donor's overall psychosocial background, mental status and donation process should also be acquired.

Mycobiology 2019;47(2):173-179
Cladophialophora is characterized by simple hyphomycetes with brown hyphae that give rise to branched chains of pale brown conidia and shows affinities with the Herpotrichiellaceae. A fungal strain belonging to the genus Cladophialophora was isolated from soil in Daegu, Korea. This strain produces numerous greenish to dark black lanose aerial mycelia with hair like structures. It is morphological similar to C. chaetospira, C. inabaensis, and C. multiseptata; however, the conidiophores and conidia sizes of the newly isolated strain (KNU16-032) are clearly different from them. The novelty of the strain was also confirmed based on phylogenetic analysis using the data sets of the internal transcribed spacer region of and the partial sequence of 28S ribosomal DNA region along with the cultural characteristics. Because morphological observations and phylogenetic analysis indicated that the strain is distinct from previously known Cladophialophora species, we propose this species as a new species Cladophialophora lanosa sp. nov., and provide the detailed descriptions in this study.

The Korean Journal of Parasitology 2019;57(3):243-248
The purpose of this study was 2-fold: 1) to investigate the prevalence of gastrointestinal parasite infection in cats reared in Daegu, Republic of Korea and 2) to assess the efficacy and safety of a topical emodepside/praziquantel formulation for cats with parasitic infections. The gastrointestinal parasite infections were examined microscopically using the flotation method. Of 407 cats, 162 (39.8%) were infected by at least one gastrointestinal parasite, including Toxocara cati (63.0%), Toxascaris leonina (31.5%), Taenia taeniaeformis (3.7%), and Cystoisospora felis (1.9%). None of the infected animals had multiple infections. When the data were analyzed according to sex, age, and type of cat, stray cats showed statistically higher prevalence than companion cats (P<0.05). On the 5th day after treatment, no parasitic eggs were detected using microscopic examination. In addition, no adverse effects, such as abnormal behaviors and clinical symptoms, were observed in the cats treated with the drug. These results quantify the prevalence of gastrointestinal parasites in cats in Daegu, Republic of Korea, and show that topical emodepside/praziquantel is a safe and effective choice for treating the parasitic infections in cats.
