OBJECTIVES: Delusions are prevalent even among members of the general population, and persecutory delusions (PDs) and grandiose delusions (GDs) are most frequently found. In this study, we investigated the differences in the dimensions of delusional ideation, reported psychosis proneness, and subjective psychotic symptoms in nonclinical individuals stratified according to the existence of PDs and GDs. METHODS: A total of 311 nonclinical individuals completed the Peters et al Delusions Inventory 40 (PDI-40), Perceptual Aberration Scale (PAS), Magical Ideation Scale (MIS), Schizotypal Personality Scale (STA), and Symptom Check List-90-R (SCL-90-R). Individuals were grouped according to four types based on the existence of PDs and GDs in PDI-40 items. RESULTS: An analysis of variance revealed that the four groups differed significantly in total delusion score, distress, preoccupation, and conviction level of delusional ideation, PAS, MAS, STA, in total SCL-90-R scores, and all SCL-90-R sub symptoms. In post-hoc analysis, the group with both PDs and GDs showed the highest scores in all measures, compared with the other three groups. CONCLUSION: We found that individuals with both PDs and GDs have a tendency to possess another delusional ideation and reported more distress, preoccupation, and conviction level of delusional ideation, psychosis proneness, and subjective symptoms. Existence of both PDs and GDs significantly elevated psychosis proneness in comparison to having only either one of them.

OBJECTIVES: Magical ideation refers to belief in forms of causation that by conventional standards are invalid, and is considered to be one of prodromal psychotic symptoms in schizophrenia. This study aimed to investigate the relationship between magical ideation and eye gaze pattern in patients with schizophrenia. METHODS: Eye gaze data were recorded in 23 patients with schizophrenia and 23 healthy controls while performing the reality evaluation task, in which participants should judge the realness of real or unreal pictures. RESULTS: Compared to healthy controls, patients with schizophrenia showed decreased fixation, saccade and area of interest (AOI) fixation counts, and reduced scanpath length. Magical Ideation Scale score in patients with schizophrenia showed negative correlation with the scanpath length in the real condition and the AOI fixation count in the unreal condition. CONCLUSION: These findings suggest that patients with schizophrenia show restricted visual scanning during reality evaluation, and their restricted visual scanning may play an important role in the magical ideation.

OBJECTIVES: We examined magical ideation in adolescent and adult group by Magical Ideation Scale (MIS). We also explored how adolescents and adults respond differently to each items of MIS. METHODS: 310 nonclinical adults and 310 Year 10 students participated in this study, and completed MIS and Symptom Checklist 90-revision (SCL-90-R). Total scores of MIS were compared between adults and adolescents. The item characteristics of MIS were evaluated by item response theory (IRT). Differential item functioning (DIF) was detected using the parameters of IRT. RESULTS: Total score of MIS was higher in adolescents than in adults, but there was no statistical significance. Item 5, 10, 13, and 16 showed significant difference on item difficulty parameters and were identified as DIF. Among DIF items, item 5 was more difficult for adolescents than adults. Item 10, 13, and 16 were more difficult for adults than adolescents. The modified MIS score excluding 4 DIF items was significantly higher in adolescents than adults. CONCLUSION: The influence of age on response to DIF items should be considered when comparing MIS scores between adolescents and adults.

5.King Injo's Disease and Burnt Needle Therapy.
Korean Journal of Medical History 2004;13(2):198-218
This paper investigates an interrelationship between burnt needle therapy and King Injo's disease. From 1633 (Year 11 in King Injo's reign) to May 5, 16. (Year 27 King in Injo's reign), right before his death, King Injo was treated with burnt needles by Yi Hyeongik, an acupuncturist when the king had health problems. This study arises from two questions: why was King Injo often treated with burnt needles? and what effect did burnt needles have? Burnt needle therapy is a combined form of acupuncture and moxibustion. Yi Hyeongik was famous for eradicating pathogenic factors. He was appointed as a doctor in the Royal Hospital. The medical definition for pathogenic factors is that they are disease-causing factors. Understanding the pathogenic factor for King Injo's disease could make it possible to find the interrelationship between burnt needles and the king's disease. In the Joseon era, the prevalent belief about diseases was that diseases could be caused by homeopathic magic. Some people thought homeopathic magic caused King Injo's disease. The actual reasons for King Injo's disease were the participation in the excessive rites of Queen Mother Inmok's funeral and the constant oppression from the Ching Dynasty after disgraceful defeat in the war. When King Injo started to be sick, homeopathic magic cases were found in the royal palace. The king's incurable disease was believed to have happened as a result of homeopathic magic. King Injo's suspicion toward Princess Jeongmyeong derived from her mother, Queen Mother Inmok. Moral justification for King Injo's coup was Gwanghaegun or Prince Gwanghae's immoral conduct toward Queen Mother Inmok. After he was installed, King Injo obeyed the Queen Mother and showed her every attention. Meanwhile, he treated Princess Jeongmyeong with respect, maximized the moral justification for the coup, and solidified the royal authority. However, constant rebellions and treasons threatened King Injo. The king suspected that Queen Mother Inmok and Princess Jeongmyeong were involved in homeopathic magic cases because both figures could affect major rebellions and treasons. Homeopathic magic is a kind of ideological belief and psychological suspicion. Accordingly, burnt needle therapy could have an actual effect on treating the diseases of the body. It could have a psychological effect in treating pathogenic factors as well. As burnt needles were often used for the king's disease, remarkable development of acupuncture and moxibustion during the King Injos era was a characteristic in the history of medical science in the Joseon Dynasty.

OBJECTIVE: To analyze subregional differences in T1rho (T1ρ) and T2 values and their correlation in asymptomatic knee cartilage, and to evaluate angular dependence with magic angles. MATERIALS AND METHODS: Six asymptomatic volunteers underwent knee MRI with T1ρ and T2 mapping. T1ρ and T2 values were measured by two radiologists independently, at nine subregions in the medial femoral condyle (MFC) cartilage, at angles of ± 0°, 15°, 35°, 55°, 75° respective to a vertical line (B0) bisecting the width of the distal femur, and at two locations in the patella. Subregional values of T1ρ and T2 were analyzed and significant differences in three divided portions of the MFC (anterior, central, and posterior) were statistically evaluated. Correlation between T1ρ and T2 and angular dependence with magic angles were also assessed for statistical significance. RESULTS: T1ρ values were lowest at +15° and highest at -55°. T2 values were lowest at +75° and highest at +35°. Both T1ρ and T2 were higher in superior patella than inferior patella. T1ρ showed significant differences in the three divided portions of the MFC, while T2 showed significant differences only between central and posterior portions. There was a weak correlation between T1ρ and T2 (r = 0.217, p = 0.127). T1ρ showed more angular dependence than T2. CONCLUSION: T1ρ and T2 showed different subregional values and angular dependence in asymptomatic knee cartilage with a weak correlation. Awareness of these differences will aid in assessment of cartilage in a specific subregion of the knee.

Tattoo involves puncturing the skin with a sharp instrument and inserting pigment through the epidermis into the dermis. People around the world have been tattooing their bodies for ages. As widely recognized, tattoo marks are found on Egyptian and Nubian mummies dating from about 2000 B.C. The culture of tattooing has had diverse meanings in different cultures. It may include cosmetic, religious and magical origins and identification of a social class. In Korea, there was a record of tattooing on forearm as a commitment to the thieves in Korea dynasty (918-1392). From a medicolegal perspective, tattoos are often used as identification markers in unknown human bodies, and have been associated with several risk factors for lethality from both suicide and accidental death. In this article, we investigated tattoo marks among the 665 autopsies performed in the Southern division of National Institute of Scientific Investigation between August 2001 and December 2002.

BACKGROUND AND PURPOSE: In order to improve inter-rater reliability and minimize diagnosis of undetermined etiology for stroke subtype classification, using a stroke registry, we developed and implemented a magnetic resonance imaging (MRI)-based algorithm for acute ischemic stroke subtype classification (MAGIC). METHODS: We enrolled patients who experienced an acute ischemic stroke, were hospitalized in the 14 participating centers within 7 days of onset, and had relevant lesions on MR-diffusion weighted imaging (DWI). MAGIC was designed to reflect recent advances in stroke imaging and thrombolytic therapy. The inter-rater reliability was compared with and without MAGIC to classify the Trial of Org 10172 in Acute Stroke Treatment (TOAST) of each stroke patient. MAGIC was then applied to all stroke patients hospitalized since July 2011, and information about stroke subtypes, other clinical characteristics, and stroke recurrence was collected via a web-based registry database. RESULTS: The overall intra-class correlation coefficient (ICC) value was 0.43 (95% CI, 0.31-0.57) for MAGIC and 0.28 (95% CI, 0.18-0.42) for TOAST. Large artery atherosclerosis (LAA) was the most common cause of acute ischemic stroke (38.3%), followed by cardioembolism (CE, 22.8%), undetermined cause (UD, 22.2%), and small-vessel occlusion (SVO, 14.6%). One-year stroke recurrence rates were the highest for two or more UDs (11.80%), followed by LAA (7.30%), CE (5.60%), and SVO (2.50%). CONCLUSIONS: Despite several limitations, this study shows that the MAGIC system is feasible and may be helpful to classify stroke subtype in the clinic.

9.Social Perception of Infertility and Its Treatment in Late Medieval Italy: Margherita Datini, an Italian Merchant's Wife.
Korean Journal of Medical History 2016;25(3):519-556
Because the perception of infertility in medieval Europe ranged from the extremely religious view of it as a malediction of God or the devil's work, to the reasonable medical conception of it as a sort of disease to treat, it is very difficult to determine the general attitudes of ordinary people towards infertility. This article seeks to elucidate the common social perception of infertility and its treatment in late medieval Europe by analyzing the case of Margherita Datini, an Italian merchant's wife who lived in the 1400s. It relies heavily on the documents left by her and her husband, Francesco Datini; the couple left many records, including letters of correspondence between them. Margherita and those around her regarded infertility not as the devil's curse or a punishment by God but as a disease that can be cured. Margherita and her husband, Francesco, tried hard to cure their infertility. They received treatment and prescriptions from several doctors while also relying on folk remedies, religious therapies, and even magical remedies. The comparative analysis of Datini documents, medical books, and theoretical treatises or prescriptive essays by clerics suggests that the general perception of infertility in medieval Europe was located between the extremely religious and modern medical conceptions of it.

OBJECTIVE: Biased attribution styles of assigning hostile intention to innocent others and placing the blame were found in schizophrenia. Attribution styles in individuals at ultra-high risk (UHR) for psychosis, however, have been less studied especially for its association with various psychological factors. We investigated whether UHR individuals show increased hostility perception and blaming bias and explored the associations of these biased styles of attribution with the factor structure of multifaceted self-related psychological variables and neurocognitive performances. METHODS: Fifty-four UHR individuals and 80 healthy controls were assessed by evaluating resilience, self-perception, self-esteem, and aberrant subjective experiences of schizotypy (physical anhedonia, social anhedonia, magical ideation, and perceptual aberration), basic symptoms, and carrying out a comprehensive neurocognitive test battery. Attribution styles were assessed using the Ambiguous Intentions Hostility Questionnaire. RESULTS: UHR individuals, compared with normal controls, showed increased hostility perception and blaming bias. Factor analysis of self-related psychological variables and neurocognitive performances in the entire subject population showed a three-factor solution, which was designated as reflective self, pre-reflective self, and neurocognition. Multiple regression analysis in UHR individuals revealed that hostility perception bias was associated with reflective self and composite blame bias was associated with reflective and pre-reflective self. CONCLUSION: This study supports the emergence of attribution biases in the putative ‘prodromal’ phase of schizophrenia. The associations of biased attribution styles with multifaceted self-related psychological constructs suggest that psychosocial interventions for biased attribution styles in UHR individuals should focus not only on reflective self but also pre-reflective self-related psychological constructs.
