  • Sleep disorders are very common among pediatric patients. Its prevalence is between 10% and 45% in preschool- and school-aged children. However parents commonly do not concern about their children's sleeping habits and for many pediatricians, there is not part of the routine office visit about a childs sleep. Sleep disorders were classified by International Classification of Sleep Disorder (ICSD) as dyssomnias, parasomnias, sleep disorders associated with mental, neurologic, or other medical disorders, and proposed sleep disorders. There are lots of differences in the causes, manifestations, and managements of sleep disorders between children and adult. The sleep disorders in childhood may manifest themselves as bedtime resistance, refusal to go to bed at a parentally described time, sleep-onset delay, inability to fall asleep within a reasonable time, prolonged nighttime awakening, and inability to return to sleep without assistance after waking during the night, and so have wide-ranging influences on children's behavior, mood, school performance, and family life. It's very important for pediatrician to concern about the sleep disturbances in childhood and so the problems of sleep in children should be early detected and managed.

  • This study analyzed the aspect of the decision of the Korean part of speech and the properties of the grammatical items based on "韓語通" which was published in 1909. "韓語通" is a Korean grammar book written by 前間恭作 who also published "校訂交隣須知" in 1904. "韓語通" is known for influencing of 'Otsuki grmmar(大槻 文法),' dividing Korean part of speech into eleven. Based on 'mood' and 'voice' we can assume that "韓語通" adopted Otsuki's grammar. '存在詞' is another clue that "韓語通" adopted Yamada's grammar. However, 前間恭作 persisted that Korean language is different from Japanese language. This view is different from 寶迫繁勝, 高橋亨, 藥師寺知? etc. This study tried to investigate the interchange of the two languages in historical study of Korean and Japanese linguistics during modern and contemporary period. For this purpose, we searched the aspect of the part of speech and analyzed the grammar items. In conclusion, we was able to light on how Japanese scholars approached to Korean grammar system in late 19th and early 20th centuries.

  • Research on obsessive-compulsive disorder (OCD) has advanced substantially since the DSM-IV was published in 1994. It is time to reexamine the nosology of this disorder, reviewing conflicting views regarding the classification as well as subtypes and specifiers of OCD. Although there is ongoing debate, OCD experts have suggested that OCD be retained in the section related to anxiety disorders and also that along with OCD, this section include obsessive-compulsive spectrum disorders (OCSD), a group of disorders closely related to OCD. A combined 'anxiety and obsessive-compulsive spectrum chapter' has also been proposed to include OCSDs. A growing body of scientific data has provided empirical support for the inclusion of a 'tic-related' subtype of OCD in the DSM-V. However, it remains controversial as to whether to introduce OCD symptom dimensions as specifiers as well as items in the diagnostic criteria. With regard to compulsive hoarding, there has been sufficient evidence to recommend that it be classified in the DSM-V as a separate disorder. Much work remains in order to ensure that the DSM-V is as evidence based as possible. It is necessary to strive toward integrating the biological and psychological data related to OCD and OCSD based on their endophenotypic features.

  • By the influence of the descriptive approach of DSM-III, the anxiety became the same thing as the anxiety disorder to the clinicians. This unfortunate result sacrificed psychodynamic model of symptom formations and simplified the anxiety as one of the disease entity not as the overdetermined symptoms. These phenomenon awakened the psychoanalytic interest which was in sleep. Freud was the first major articulator of the basic significance of anxiety in human behavior. He attributed the particular quality of the anxiety experience to the trauma of birth, and subsequently to the fear of castration. Such classification of the anxiety according to the psychosexual development is helpful for the clinicians in understanding the origin of anxiety which the patient shows during the psychotherapy. The other analytical view of interpersonal psychoanalysis came from Sullivan. A large part of his therapy is taken up with recognizing and correcting parataxic distortions that interfere with realistic self-appraisal of events and of oneself in relation to others. Perhaps no explanation is the 'most basic' explanation for human anxiety. Anxiety is a multifaceted entity consisting of aspects of realm of discourse. Existential anxiety is inescapable in Western culture but it can be transcended by the cultivation of mind in Eastern culture. The analysts need to stay attuned to their own propensities for anxiety and must permit their own experiences with anxiety to be the grist for the psychotherapeutic mill.

  • Recently, the importance of big data continues to be emphasized, and it is applied in various fields based on data mining techniques, which has a great influence on the health care industry. There are many healthcare industries, but only home health care is considered here. However, applying this to real problems does not always give perfect results, which is a problem. Therefore, data mining techniques are used to solve these problems, and the algorithms that affect performance are evaluated. This paper focuses on the effects of healthcare services on patient satisfaction and satisfaction. In order to use the CVParameterSelectin algorithm and the SMOreg algorithm of the classify method of data mining, it was evaluated based on the experiment and the verification of the results. In this paper, we analyzed the services of home health care institutions and the patient satisfaction analysis based on the name, address, service provided by the institution, mood of the patients, etc. In particular, we evaluated the results based on the results of cross validation using these two algorithms. However, the existence of variables that affect the outcome does not give a perfect result. We used the cluster analysis method of weka system to conduct the research of this paper.

  • Objectives: The purpose of this study is to examine the magnitude of and the factors associated with the downward mobility of first-episode psychiatric patients. Methods: This study used the claims data from the Korean Health Insurance Review and Assessment Service. The study population included 19 293 first-episode psychiatric inpatients diagnosed with alcohol use disorder (International Classification of Diseases, 10th revision [ICD-10] code F10), schizophrenia and related disorders (ICD-10 codes F20-F29), and mood disorders (ICD-10 codes F30-F33) in the first half of 2005. This study included only National Health Insurance beneficiaries in 2005. The dependent variable was the occurrence of downward mobility, which was defined as a health insurance status change from National Health Insurance to Medical Aid. Logistic regression analysis was used to assess factors associated with downward drift of first-episode psychiatric patients. Results: About 10% of the study population who were National Health Insurance beneficiaries in 2005 became Medical Aid recipients in 2007. The logistic regression analysis showed that age, gender, primary diagnosis, type of hospital at first admission, regular use of outpatient clinic, and long-term hospitalization are significant predictors in determining downward drift in newly diagnosed psychiatric patients. Conclusions: This research showed that the downward mobility of psychiatric patients is affected by long-term hospitalization and medical care utilization. The findings suggest that early intensive intervention might reduce long-term hospitalization and the downward mobility of psychiatric patients.
