Thrombotic thrombocytopenic purpura(TTP) is a rare but life-threatening multi-system disorder characterized by the classic pentad of clinical features that includes fever, microangiopathic hemolytic anemia, thrombocytopenia, neurologic abnormalities and renal dysfunction. TTP has been rarely reported to simultaneously present with systemic lupus erythematosus (SLE). While it is important to distinguish between the two diseases of therapeutic implication, cases of concurrent TTP and SLE help to elucidate the pathophysiology that underlies each condition. We describe two adolescents with synchronous TTP and SLE, and review the literature.

This report documents the clinical k pathologic features of 33 patients treated for thymoma for 11 years & 6 months between September 1977 and February 1989. At the Thoracic & Cardiovascular Surgery, Yonsei University, College of Medicine of the group, 31 patients treated with surgery were examined for the result of operation & prognosis. Mean age was 50 years. Thirteen were female and twenty were male. Dyspnea on exertion and chest discomfort were common in the patients without myasthenia gravis. Fourteen patients[42.6%] had myasthenia gravis and one patient had autoimmune thyroid disease. Four patients[12.1%] presented without symptoms attributable to their thymoma. Histologic review disclosed 12[36.4%] epithelial thymoma, 10[30.3%] mixed lymphoepithelial, 9[27.3%] lymphocytic, 1[3.0%] spindle cell and 1[3.0%] unknown cell thymoma. They were classified according to Masaoka`s clinical staging criteria; by these criteria, 8 patients were stage I, 5 patients were stage II, 15 patients were stage III and 3 patients were stage IV. Total excision of mass was possible in 20 patients. Partial excision of mass in 4 patients and biopsy in 7 patients were carried out during the operation. There was only one operation mortality. Follow-up was possible in 26 patients and follow-up ranged from 4 months to 10.5 years[mean 28.9 months]. One-year survival rates were 77.8% and eight patients expired during follow-up period. Eleven[78.6%] patients with myasthenia gravis were improved after the operation. This observation suggests that the most significant factor determining the survival is whether or not total surgical excision had been performed.

Pleuropulmonary blastoma is a rare malignant neoplasm which originates from either the lungs or pleura. Pleuropulmonary blastoma usually develops in the first decade of life, mostly younger than 5 years old and shows aggressive biological behavior. Pleuropulmonary blastoma is discriminated from classic pulmonary blastoma of adulthood by its morphological features like primitive mesenchymal and sarcomatous component without carcinomatous portions. To our knowledge, report of pleuropulmonary blastoma in adulthood is very rare. Our case support the possibility that primitive neoplasm recognized as pediatric tumors can develop in adulthood. We report a case of surgical experience of pleuropulmonary blastoma which developed in 21 years old man with literature review.

The number of disasters caused by natural or human-made events such as earthquakes, tsunamis, floods, typhoons, industrial disasters, and the recent outbreak of COVID-19 has increased and the damage caused by such disasters is increasing every year. Disasters can cause physical destruction and also have unexpected psychological impacts, such as post-traumatic stress disorder (PTSD). Ear acupuncture is a treatment modality that can be helpful for both physical and mental health problems. Since ear acupuncture is a cost-effective, flexible, and safe treatment tool, it has the potential to provide medical assistance in disasters. The National Acupuncture Detoxification Association (NADA) auricular acupuncture protocol, originally developed for addiction treatment, has been used for mental illness and behavioral symptoms in both community health settings and in a variety of disaster, terror, and refugee settings. In this review, we introduced the NADA protocol, including its history, features, training, clinical evidence, and cases in disaster settings, suggesting that the NADA protocol could be utilized as a disaster medical support model in Korean medicine.

Premenstural dysphoric disorder(PMDD) imposing 4-5% of women is possibly caused by an enhanced responsiveness to the changes of sex steroid hormones and the decrease of serotonin, melatonin and GABA. The common clinical features between PMDD and depression, seasonal affective disorder, panic disorder and anorexia nervosa suggest a relatedness between PMDD and each of them. The diagnostic criteria of DSM-IV-Tr for PMDD requires psychological symptoms, that commonly include irritability, anger, depression, mood swing, affect lability, tension, anxiety, fatigue and food craving. As of today, the best pharmacological treatment for PMDD is the selective serotonin reuptake inhibiter, and leuprolide, danazol, estradiol, spironolactone and bromocriptine are possible alternatives. Nonpharmacological treatments for patients with mild to moderate symptom severity are diet, exercise, light therapy, psychotherapy and keeping a diary.

The purpose of this study is to estimate consumer preferences on hybrid cars and electric cars by employing a choice experiment reflecting the various market conditions, such as different projected market shares of green vehicles and $CO_2$ emission regulations. Depending on different market scenarios, we examine as to which attribute and individual characteristic affect the preferences of potential consumers on green vehicles and further, forecast the potential market shares of green cars. The primary results, estimated by a conditional logit and panel probit models, indicate that sales price, fuel cost, maximum speed, emission of air pollutants, fuel economy, and distance between fuel stations can significantly affect consumer's choice of environment-friendly cars. The second finding is that the unique features of electric cars might better appeal to consumers as the market conditions for electric cars are improved. Third, education, age, and gender can significantly affect individual preferences. Finally, as the market conditions become more favorable toward green cars, the forecasted market shares of hybrid and electric vehicles will increase up to 67% and 14%.

This study was performed in order to evaluate the accuracy and the usefulness of the cytology of crush preparation in central nervous system (CNS) lesions. Forty four intraoperative biopsies were performed at the time of craniotomy including 34 benign and 10 malignant lesions. Crush preparations were prepared from tiny tissue fragments of craniotomy products. All cases were stained with toluidine blue. Intraoperative diagnoses made on cytologic examination were compared with the final paraffin section diagnoses. Comparison between the results of the cytologic and histologic findings revealed an overall diagnostic accuracy of 88.6%. This study attests to the diagnostic accuracy of cytologic examination in CNS lesions. The detailed cytologic features are described and important criteria for the cytodiagnosis of CNS lesions are discussed. This review leads us to think that cytologic examination by crush preparation in CNS lesions is considered as a simple, safe and highly diagnostically accurate method.

This is a review on the longitudinal transformation of the Japanese trousers, which is prepared as a pre-study for the comparative analysis of the forms of Korean and Japanese folk trousers. The special traits of the Japanese trousers are found to be as follows: 1) The Japanese trousers seem to have their root in the Northern-Asian or Schithian culture. 2) While the ancient forms of Japanese trousers, esp., those of the 8C before include the same types as Korean folk trousers, the Medieval and Recent era trousers quite differ and transform themselves into the unique Japanese type. 3) All Japanese trousers can largely be classified into formal and functional trousers. Formal trousers play important role as one of the ceremonial wardrobe and are treated rather as an outermost-wear than as an inner-wear. 4) The formal trousers have skirt-like features with much fullness as are presented in many deep pleats, long crotch lines and long sashes connected to the belt; the femine trousers even omit crotch line. 5) The principal forms of Japanese trousers consist of I, $\wedge,\;\wedge$; the $\lambda$ form of Korean and Chinese type had never existed. 6) Varieties of the composite type of Japanese-Western style appear among the trousers of recent time.

Text classification is one of the fundamental techniques in natural language processing. Numerous studies are based on text classification, such as news subject classification, question answering system classification, and movie review classification. Traditional text classification methods are used to extract features and then classify them. However, traditional methods are too complex to operate, and their accuracy is not sufficiently high. Recently, convolutional neural network (CNN) based one-hot method has been proposed in text classification to solve this problem. In this paper, we propose an improved method using CNN based skip-gram method for Chinese text classification and it conducts in Sogou news corpus. Experimental results indicate that CNN with the skip-gram model performs more efficiently than CNN-based one-hot method.

In this study, we tried to analyze the relative importance of features for various functions provided by Discovery. We identified a total of 36 assessment items in five categories including contents, search function, serendipity, interactivity, and ease of use based on literature review. In order to objectively evaluate the relative importance of each evaluation element, an AHP technique was adopted. As a result, 'Easy of use' received the highest weighted value among the five categories, followed by 'contents', 'search function', 'interactivity', and 'serendipity'. In addition, among all the 36 assessment items, 'Quality of data for central index' had higher weighted value. These findings can be used as basic data to adopt a discovery tool for libraries.
