최근 들어 소리의 세기나 하모니, 템포, 리듬 등의 다양한 음악 신호 특성을 기반으로 한 음악 무드 분류에 대한 연구가 활발하게 진행되고 있다. 본 논문에서는 음악 무드 분류의 정확도를 높이기 위하여 음악 신호 특성과 더불어 노래 가사와 소셜 네트워크 상에서의 사용자 평가 등을 함께 고려하는 멀티 모달 음악 무드 분류 기법을 제안한다. 이를 위해, 우선 음악 신호 특성에 대해 퍼지 추론 기반의 음악 무드 추출 기법을 적용하여 다수의 가능한 음악 무드를 추출한다. 다음으로 음악 가사에 대해 TF-IDF 기법을 적용하여 대표 감정 키워드를 추출하고 학습시킨 가사 무드 분류기를 사용하여 가사 음악 무드를 추출한다. 마지막으로 소셜 네트워크 상에서의 사용자 태그 등 사용자 피드백을 통한 음악 무드를 추출한다. 특정 음악에 대해 이러한 다양한 경로를 통한 음악 무드를 교차 분석하여 최종적으로 음악 무드를 결정한다. 음악 분류를 기반한 자동 음악 추천을 수행하는 사용자 만족도 평가 실험을 통해서 제안하는 기법의 효율성을 검증한다.

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.

본 연구는 "한어통(韓語通)"을 대상으로 한국어의 품사 설정 양상과 체계 및 문법 항목의 기술상에 나타난 특징을 살펴본 것이다. 본서는 1904년 "교정교린수지(校訂交隣須知)"를 간행한 마에마 교사쿠(前間恭作, 이하 마에마)가 1909년에 펴낸 한국어 문법서로 한국어 품사를 총 11개로 나누었다. 이와 같이 '서법(mood)'과 '태(voice)'의 개념과 설명을 부가하여 '오쓰키문법(大槻文法)'의 영향이 적지 않게 반영되었다고 평가받는 대표적인 문법서라고 할 수 있는 가운데 '존재사(存在詞)'의 개념을 언급함으로써 '야마다문법(山田文法)'의 관점을 차용한 양상도 보인다. 그러나 마에마는 1880년의 호세코 시게카쓰(寶迫繁勝) 및 마에마와 같은 해인 1905년의 다카히시 도오루(高橋亨), 야쿠시지 지로(藥師寺知?) 등과는 달리 한국어와 일본어가 다르다는 전제하에 한국어의 문법 현상을 규명하려는 입장을 견지하고 있다. 이번 연구는 근현대 한일문법학사에 나타난 양국어의 교섭을 구명하기 위한 하나의 시도로 본서의 품사 구분 경향과 문법 항목의 기술상에 보이는 내용적 분석을 병행하여보고자 한다. 이를 통해 개화기말, 20세기 초라고 하는 시기에 한국어 문법의 체계화가 일본인의 관점에서 어떻게 이루어지고 있는지 그 일면을 파악하는데 일조하고자 한다.

이미지를 분류하고 검색하는 기술(Image retrieval)중 하나인 Bag of visual words(BoVW)는 특징점(feature point)을 이용하는 방법으로 데이터베이스의 이미지 특징벡터들의 분포를 통해 쿼리 이미지를 자동으로 분류하고 검색해주는 시스템이다. Words를 구성하는데 특징벡터만을 이용하는 기존의 방법은 이용자가 원하지 않는 이미지를 검색하거나 분류할 수 있다. 이러한 단점을 해결하기 위해 특징벡터뿐만 아니라 이미지의 전체적인 분위기를 표현할 수 있는 색상정보나 반복되는 패턴 정보를 표현할 수 있는 텍스처 정보를 Words를 구성하는데 포함시킴으로서 다양한 검색을 가능하게 한다. 실험 부분에서는 특징정보만을 가진 words를 이용해 이미지를 분류한 결과와 색상정보와 텍스처 정보가 추가된 words를 가지고 이미지를 분류한 결과를 비교하였고 새로운 방법은 80~90%의 정확도를 나타내었다.

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.

Objectives The purpose of this study was to investigate the premenstrual symptoms according to Sasang constitution and to utilize for understanding the characteristics of Sasang constitution. Methods Thirty one female university students participated in this study and Sasang Constitution and patterns of premenstrual symptoms was determined by Questionnaire for Sasang Constitution Classification (QSCC) II and premenstrual symptoms screening tool, respectively. For statistical analysis, chi-square test, analysis of variance and correlation test has been used. Results There existed significant differences in menstrual symptoms between Sasang constitutions. Taeumin had higher body mass index in severe PMS(Premenstrual Symptoms) group than normal/mild PMS group, and Soyang in and Soeumin are vice versa. Taeumin showed depressed mood and hopelessness, decreased interest in school activities, Soyangin showed decreased interest in home activities, and Soeumin showed decreased interest in social activities. In terms of interfered functional activities, Soyangin had increased feeling overwhelmed or out of control and Taeumin and Soeumin had increased hypersomnia. Conclusion Menstrual symptoms are different among Sasang constitutional types based on PSST(Premenstrual Symptoms Screening Tool). These results may serve as the basis in identifying and treating premenstrual syndromes related to Sasang constitution.

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.
