2.Statistical basis for pharmacometrics: random variables and their distribution functions, expected values, and correlation coefficient.
Translational and Clinical Pharmacology 2016;24(2):66-73
For pharmacometricians, probability theory is the very first obstacle towards the statistics since it is solely founded on mathematics. The purpose of this tutorial is to provide a simple version of introduction to a univariate random variable, its mean, variance, and the correlation coefficient of two random variables using as simple mathematics as possible. The definitions and theorems in this tutorial appear in most of the statistics books in common. Most examples are small and free of subjects like coins, dice, and binary signals so that the readers can intuitively understand them.

Annals of Dermatology 1993;5(2):130-132
We report a case of a morphologic variant of dermatofibroma. A coin sized, brownish, shinny, somewhat fibrotic pedunculated tumor in a 39-year-old male was diagnosed as a sclerosing hemangioma, a type of dermatofibroma histopathologically. Its dome shape morphology was unusual in comparison with the typical morphology of dermatofibroma that we know.

Tumor of follicular infundibulum is the term coined by Mehregan and Butler in 1961 for a benign hyperplastic lesion that extends from the follicular infundibulum as an epithelial plate with underlying elastic fiber network. This tumor appears as a slightly elevated keratotic lesion and is characterized histologically by proliferation of follicular sheath epithelium in the form of a thin subepidermal plate. We present a typical case of tumor of follicular infundibulum in the left shoulder area of 74 year-old-man. To the best of our knowledge, this is the first reported case of a solitary tumor of follicular infundibulum in Korea.

5.Two Cases of Chronic Cutaneous Graft-versus-host-reaction on the Site of Healed Herpes Zoster as an Isotopic Response.

Korean Journal of Dermatology 2008;46(1):90-93
The term 'isotopic response' was coined by Wolf to describe the emergence of a new skin disease at the site of another, unrelated, and already healed skin disease; most commonly herpes zoster. In the dermatologic literature, although a number of cutaneous lesions have been observed to develop at the site of healed herpes zoster, chronic cutaneous graft-versus-host reaction has been rarely reported. We herein report two cases of chronic cutaneous graftversus-host reaction which clinically presented as an isotopic response.

6.Aneurysmal Bone Cyst in Clavicle: Report of A Case

Aneurysmal bone cyst is a rare, non-neoplastic condition, which was first coined by Jaffe and Lichtenstein in 1942. Clavicle is an unusual site for aneurysmal bone cyst. Authors present a case of aneurysmal bone cyst which was found in the right clavicle of a 5 years old boy, because of its rarity of site of predilection.

INTRODUCTION: Attention-deficit hyperactivity disorder (ADHD) was a newly coined term for a disease that existed prior to its naming in the mid 20th century. The issue about whether ADHD is a new disorder or merely a new name for an existing disorder is still controversial. The authors tried to find the clues to the answer for this question through reviewing historical documents for traces of ADHD. CONTENTS: We could find literatures and medical records that contain possible ADHD symptoms. In particular, in 1845, Heinrich Hoffmann's 'fidgety Philip' or 'Johnny Look-in-the-air' nearly satisfies today's criteria for ADHD. Methylphenidate was approved as a promising chemical for inattention in 1957 before the establishment of the concept of ADHD. In 1968, ADHD was first officially introduced as "Hyperactivity Reaction of Childhood" by DSM-II. In 1980, DSM-III, 'Attention Deficit Disorder (ADD)' was adopted as an official diagnostic term and changed to 'ADHD' since the creation of DSM-III-R in 1987. CONCLUSION: As stated above, ADHD has existed since long ago and became familiar via an advanced diagnostic system and therapeutic options.

9.CT Findings of Foreign Bodies in the Chest: A Pictorial Essay.

Journal of the Korean Radiological Society 2008;58(5):495-501
The most common causes of tracheobronchial foreign bodies are peanuts in children, and meat and dentures in adults. The most common causes of esophageal foreign bodies are coins in children and meat in adults. It is possible to diagnose a foreign body by visualization on a chest radiograph, if the foreign bodies are radioopaque. However, if the foreign bodies are radiolucent and the patients do not remember the history of aspiration, it is important to evaluate CT findings for foreign bodies and their complications. We describe the CT findings of various thoracic foreign bodies in children and adults.

Journal of Korean Neurosurgical Society 1981;10(2):651-658
The size of the cisterna magna is still detatable. Robertson13) stated that the cisterna magna varies greatly in capacity and described the large cisterna magna as a separate entity. He also found that in most cases the cisterna magna extended approximately 2.5cm above the foramen magnum and was usually 5mm deep with a variable width. Liliequist8) proposed a mean heigh of 28mm for the normal cisterna magna with a wide variation of 15 to 60mm, and a depth of 6mm at the foramen magnum with a variation of 2 to 10mm:however, he did not quote measurements for the width. Gonsette, et al.5) reported 28 cases of enlarged cisterna magna diagnosed by ventriculography and coined the phrase "mega grande citerne" or mega cisterna magna. All of these cases, however, had symptoms of posterior fossa disease. Our study of the syndrome of the mega cisterna magna without specific syndrome is presented nystagmus, transient syncope in the first & third cases were operated under suboccipital craniectomy and was confimed the large cisterna magna. This paper presents the clinical diagnosis with vertebral angiogrraphy, pneumoencephalography and computed tomography.
