A folksonomy is a classification system in which volunteers collaboratively create and manage tags to annotate and categorize content. The folksonomy has several problems in retrieving music using tags, including problems related to synonyms, different tagging levels, and neologisms. To solve the problem posed by synonyms, we introduced a mood vector with 12 possible moods, each represented by a numeric value, as an internal tag. This allows moods in music pieces and mood tags to be represented internally by numeric values, which can be used to retrieve music pieces. To determine the mood vector of a music piece, 12 regressors predicting the possibility of each mood based on acoustic features were built using Support Vector Regression. To map a tag to its mood vector, the relationship between moods in a piece of music and mood tags was investigated based on tagging data retrieved from Last.fm, a website that allows users to search for and stream music. To evaluate retrieval performance, music pieces on Last.fm annotated with at least one mood tag were used as a test set. When calculating precision and recall, music pieces annotated with synonyms of a given query tag were treated as relevant. These experiments on a real-world data set illustrate the utility of the internal tagging of music. Our approach offers a practical solution to the problem caused by synonyms.

Purpose: This study was done to examine differences in the factors affecting Hwa-byung symptoms in middle-aged men and women. Method: There search design for this study was a descriptive survey design using a convenience sampling. Data collection was done using self-report questionnaires with 381 middle age people (169 men and 212 women) in Seoul and G city. ANOVA, t-test, Pearson correlation coefficients and stepwise multiple regression were used to analyze the data with SPSS Win 18.0 Program. Results: There were significant differences in Hwa-byung symptoms and life stress between men and women. However anger rumination and mood states were not significantly different by gender. In multiple regression analysis, mood states, religion, and employment were significant predictors and explained 36% of Hwa-byung symptoms for men. In women, mood states, life stress, anger rumination and employment were significant predictors and explained 41% of Hwa-byung symptoms. Conclusion: Findings of this study provide a comprehensive understanding of Hwa-byung symptoms and related factors between men and women in Korea. However, further study with a larger random sample from various living environment is necessary.

Effects of physical attributes of workstation enclosures on the performance of office workers with different difficult levels of office tasks and moods are presented. Performance scores in complex tasks were expected to increase with greater workstation enclosures while those in simple tasks would be the same. Mood ratings were expected to be higher in lower workstation enclosures. Performance of 102 college students on ambient office sounds (45 dBA) with office tasks were measured for 100 minutes under three different workplace enclosures: (1) four foot partitions on two sides; (2) six foot partitions on three sides; and (3) a fully enclosed workstation with eight foot partitions. The tasks were to memorize a paragraph with 130 words (complex task) and to search phone numbers (simple task). The complex task performance in the fully enclosed workstation was increased compared to that in the workstation with four foot partitions (p < 0.001) and to that in the workstation with six foot partitions (p < 0.05). However, occupants in the fully enclosed workstation with office sounds without speech generally gave higher mood ratings. It indicates that closed individual offices may offer important contributions to collaborative work as well as individual productivity. These findings would help design community revise open plan design to increase collaboration among office workers.

이 글에서 논자는 오늘날 불안의 실존적 현상들을 살펴봄으로써 불안의 진단과 치료에 있어서 철학적 근거를 드러내보고자 한다. 특히 불안의 근원을 심리적 차원과 더불어 윤리적 차원을 통해 살펴봄으로써 심리적 현상으로서 불안의 철학적 근거를 강조하고자 한다. 이를 위해 가능성과 현실성 '사이존재(Zwischesein)'로서 실존 그리고 존재의 분열과 봉합 사이의 순간이 수반하는 '사이기분(Zwischenstmmung)'으로서 불안을 드러낸다. 불안의 근거로서 실존이 지닌 '사이성(Zwischeheit)'에 대한 주목은 키에르케고어($S{\ddot{o}}ren$ Kierkegaard)에 의해 '종합' 개념 속에서 나타지만 '두 개 사이의 관계'로서 그의 종합 개념은 오히려 종합이라는 용어로 인하여 충분히 주목되지 못했다. 논자는 사이성에 대한 조명을 통하여 실존 개념이 지니는 보다 심층적 조건을 포착해본다. 그리하여 논자는 분열된 양자 사이의 종합이라는 결과보다는 그 양자 사이의 긴장이라는 과정에 주목해본다. 이 를 위해 실존철학의 선구자인 키에르케고어의 "불안의 개념"을 분석한다.

Numerous investigators have conducted extensive investigation in the search for biological markers in psychiatric illness. There are, as a test of q biological approach to the diagnosis of the psychiatric illness, tests for the neurotransmitters, their metabolites, and related enzymes, the neurotransmitter receptors, the neuroendocrine output and response, the membrane transport, peptides and eletrolytes. They are called the biological markers, and they are helpful for the diagnosis or differential diagnosis, choice of treatment or drugs, symptom improvement, predictor of recurrence and anticipation of suicidal attempt. These studies are among the main purposes that are pursued in the neuroscience and based on the potential utility of the biological markers mentioned above. Since 1970's, lots 01 biological markers' studies for the diagnosis, differential diagnosis or subtypes differentiation have been done but varieties of different opinions have been drawn since then through they could explain the charaters of main psychiatric illness(especially schizophrenia and mood disorder). But, the search for biological markers, including displines of neuroendoclinology and neurochemistry(neurotransmitter and thair metabolite), has yielded a number of putative trait merkers and state markers for psychayric illness. This paper aims to anticipate or evaluate the good response to the therapy(Therpeutic response) with lots of markers. Acoording to the diagnosis of lots of diseases or subtypes, we are going to review the papers, mainly concern with 'Is there any Marker' or 'Is any test possible to detect the improvement clinically?' 'Is it possible to predict the recurrence or good prognsis?' or 'Is it possible to select any drug or therapy to bring the good response?' The biological tests to review are mainly the metabolites of catecholamine neurotransmitter, and especially neuroendocrine test based on the knowledge that hormons of the adenohypophysis are influenced by activity of the cerebral or limbic neurons as well as the hypothalamus ones. Among them, author introduced some clinically available tests that are DST, TRH stimulation test(TRHST), GH stimulation test, and the urine MHPG test that can give us the evaluation of the treatment response, the predictor for recurrence or choice of drug that can bring a good response. So author discussed thair potential utility in clarifying, therapeutic, and prognostic issues in psychatric illness. We hope they'll be used and look forward to more active study on the different opinion.

Purpose: Studies focus on cancer control, prevention, or assessment of psychosocial problems and intervention methods. However, few studies exist concerning psychosocial problems, measuring tools for those problems, and interventions for cancer patients in Korea. One of the purposes of this study was to review studies in this area, to examine various psychosocial problems experienced by cancer patients. This is a crucial area to investigate, since psychosocial problems in turn negatively influence the patients' immune function, which speeds the progress of the disease. Another goal was to identify instruments used to measure psychosocial functioning and problems in cancer patients, to analyze their validity and reliability, with the aim to discover the best instruments. A final goal was to explore and compare the effects of psychosocial interventions, to determine the most effective practices. Method: Journal articles published since 1995 were searched from PubMed Data base, Google search engine, and published cancer-related studies, using search keywords "psychosocial function and intervention for the cancer patients"; whole articles of selected references were reviewed and analyzed. Result: Most common psychosocial problems were depression, fatigue, nausea, pain, distress, resulting in a low quality of life. The seven scales found in the literature to assess the psychosocial functioning were Center for Epidemiological Studies-Depression, State-Trait Anxiety Inventory, Symptom Checklist 90-R, Profile of Mood States, Psychosocial Adjustment to Illness Scale, Brief Symptom Inventory, and SF-36 HRQOL(Health Related Quality of Life). Social support interventions for cancer patients were effective in improving quality of life scores. Conclusion: It is necessary to apply support intervention strategies to help cancer patients in Korea. These strategies can help to reduce the effects of psychosocial symptoms, which in turn affect the development and control of cancer. Strategies developed in Western countries may need to be modified for use within Korea. Further studies are warranted to review the support intervention strategies that were being used to for cancer patients

Background: Experience of lung cancer includes negative impacts on both physical and psychological health. Pain is one of the negative experiences of lung cancer. Cognitive behavioral therapy techniques are often recommended as treatments for lung cancer pain. The objective of this review was to synthesize the evidence on the effectiveness of cognitive behavioral therapy techniques in treating lung cancer pain. This review considered studies that included lung cancer patients who were required to 1) be at least 18 years old; 2) speak and read English or Thai; 3) have a life expectancy of at least two months; 4) experience daily cancer pain requiring an opioid medication; 5) have a positive response to opioid medication; 6) have "average or usual" pain between 4 and 7 on a scale of 0-10 for the day before the clinic visit or for a typical day; and 7) able to participate in a pain evaluation and treatment program. This review considered studies to examine interventions for use in treatment of pain in lung cancer patients, including: biofeedback, cognitive/attentional distraction, imagery, hypnosis, and meditation. Any randomized controlled trials (RCTs) that examined cognitive behavioral therapy techniques for pain specifically in lung cancer patients were included. In the absence of RCTs, quasi-experimental designs were reviewed for possible conclusion in a narrative summary. Outcome measures were pain intensity before and after cognitive behavioural therapy techniques. The search strategy aimed to find both published and unpublished literature. A three-step search was utilised by using identified keywords and text term. An initial limited search of MEDLINE and CINAHL was undertaken followed by analysis of the text words contained in the title and abstract, and of the index terms used to describe the article. A second search using all the identified keywords and index terms was then undertaken across all included databases. Thirdly, the reference list of all identified reports and articles were searched for additional studies. Searches were conducted during January 1991- March 2014 limited to English and Thai languages with no date restriction. Materials and Methods: All studies that met the inclusion criteria were assessed for methodological quality by three reviewers using a standardized critical appraisal tool from the Joanna Briggs Institute (JBI). Three reviewers extracted data independently, using a standardized data extraction tool from the Joanna Briggs Institute (JBI). Ideally for quantitative data meta-analysis was to be conducted where all results were subject to double data entry. Odds ratios (for categorical data) and weighted mean differences (for continuous data) and their 95% confidence intervals were to be calculated for analysis and heterogeneity was to be assessed using the standard Chi-square. Where statistical pooling was not possible the finding were be presented in narrative form. Results: There were no studies located that met the inclusion requirements of this review. There were also no text and opinion pieces that were specific to cognitive behavioral therapy techniques pain and lung cancer patients.Conclusions: There is currently no evidence available to determine the effectiveness of cognitive behavioural therapy techniques for pain in lung cancer patients.
