The main goal of this research is to build a sentiment analysis system which automatically determines user opinions of the Stanford Sentiment Treebank in terms of three sentiments such as positive, negative, and neutral. Firstly, sentiment sentences are POS tagged and parsed to dependency structures. All nodes of the Treebank and their polarities are automatically extracted from the Treebank. We train two Support Vector Machines models. One is for a node level classification and the other is for a sentence level. We have tried various type of features such as word lexicons, POS tags, Sentiment lexicons, head-modifier relations, and sibling relations. Though we acquired 74.2% in accuracy on the test set for 3 class node level classification and 67.0% for 3 class sentence level classification, our experimental results for 2 class classification are comparable to those of the state of art system using the same corpus.

Conduct disorder has been subclassified by the symptom characteristics of socialization, aggression, or age of onset. In ICD-10, ‘Conduct disorder confined to family context’ has been developed as a distinct subtype. Which delineates the conduct problems which take place only in the family and related situation. These authors experienced a case which presents a child who shows aggressive and violent behavior to his parent and brother, severe tamper tantrum and destructiveness only in family. By through history taking, observation and treatment after admission, we could find that insecure and ambivalent attachment between parent and child due to chronic neglect and abuse, and inconsistent parental behavior contribute to many behavioral and emotional problems of this child. We reviewed the relationship between conduct disorder and family pathology and treatment strategy for conduct disorder with family problems.

본 연구의 목적은 저소득층 편부모의 자아통제가 심리적 안녕감에 미치는 요인들을 살펴봄으로써 이들 대상의 심리적 안녕감을 향상시킬 수 있는 정색적 시사점을 얻고자 하였다. 본 연구는 편의표본추출방법에 따라 저소득층이 밀집된 48개 지역에 거주하는 635명의 편부모를 대상으로 구조화된 자기 기입식 설문지를 이용만 우편설문조사를 실시하였다. 본 연구에서 종속 변수인 심리적 안녕감은 우울증, 자존감, 삶의 만족도 등이며, 독립변수로 인구사회적 배경 요인(모델 1), 사회적 지원 요인(모델 2), 자아통제 요인(모델 3) 등이 사용되었다. 본 연구의 주요 초점인 자아통제 요인은 내외통제성, 적극적 대처, 소극적 대처 등으로 구성되었다. 자료분석은 위계적 다중회귀분석(Hierarchical Multiple Regression Analysis)이 활용되었다. 본 연구에서 나타난 주요 결과는 다음과 같다. 1) 우울증 모델에서는 자아통제 요인이 모두 유의한 영향을 미치는 것으로 판명되었다. 내적 통제감이 높고 소극적 대처력이 낮고 적극적 대처력이 높을수록 우울증이 낮게 나타났다. 다른 유의한 변인은 건강상태로 건강할수록 우울증이 낮았다. 2) 자존감 모델에서는 자아통제 요인 중 내외통제청과 적극적 대처력이 유의한 변인으로 판명되어, 내적 통제감이 놓고 적극적 대처를 많이 하는 편부모일수록 자존감이 높았다. 또한 고연령이고, 건강상태가 좋고, 종교를 갖고 있으며 자녀와의 관계가 가까울수록 자존감이 높았다. 3) 삶의 만족도 모델에서는 자아통제, 소극적 대처, 적극적 대처가 유의한 변인으로 분석되어, 내적 통제감이 높고, 소극적 대처는 낮으며 적극적 대처력이 높은 편부모가 삶의 민족도가 높은 것으로 나타났다. 수입, 건강, 종교, 자녀와의 관계는 두 모델에서는 유의하였으나, 자아통제 요인을 첨가하자 의미성이 없어졌다. 예상외로 부모, 형제, 친구, 공공기관, 종교기관으로부터 받는 사회적 지지는 거의 모든 모델에서 유의한 영향을 주지 않았다. 이러한 결과는 저소득층에게 제공되어지는 사회적 지지가 미미한 편으로 변이가 없기 때문으로 해결될 수 있다. 따라서, 저소득층 편부모에게 사회적 지지는 물론 자아통제를 제고하는 것이 그들의 심리적 안녕감을 높게 하는 주요 방안이라 팔 수 있다. 앞으로 저소득층 편부모의 자아통제를 제고할 수 있는 다양한 프로그램의 개발 및 이의 적극적 실행방안이 모색되어야 할 것이다.

As demand for efficiency in handling dynamic XML data grows, new dynamic XML labeling schemes have been researched. The key idea of the dynamic XML labeling scheme is to find ancestor-descendent-sibling relationships and to minimize memory space to store total label, response time and range of relabeling incurred by update operations. The prime number labeling scheme is a representative scheme which supports dynamic XML documents. It determines the ancestor-descendant relationships between two elements by a simple divisibility test of labels. When a new element is inserted into the XML data using this scheme, it does not change the label values of existing nodes. However, since each prime number must be used exclusively, labels can become significantly large. Therefore, in this paper, we introduce a novel technique to effectively reduce the problem of label overflow. The suggested idea is based on tree decomposition. When label overflow occurs, the full tree is divided into several sub-trees, and nodes in each sub-tree are separately labeled. Through experiments, we show the effectiveness of our scheme.

Recently, the needs for an efficient and secure access control method of dynamic XML data in a ubiquitous data streams environment have become an active research area. In this paper, we proposed an improved role-based prime number labeling scheme for an efficient and secure access control labeling method in dynamic XML data streams. And we point out the limitations of existing access control and labeling schemes for XML data assuming that documents are frequently updated. The improved labeling method where labels are encoded ancestor-descendant and sibling relationships between nodes but need not to be regenerated when the document is updated. Our improved role-based prime number labeling scheme supports an infinite number of updates and guarantees the arbitrary nodes insertion at arbitrary position of the XML tree without label collisions. Also we implemented an efficient access control using a role-based prime number labeling. Finally, we have shown that our approach is an efficient and secure through experiments.

This study explored in-depth emotional experiences influenced by childhood trauma of adult female survivors. For this purpose, in-depth interviews were conducted with married adult women who experienced trauma in their childhood. The collected data were analyzed using Colaizzi phenomenological research method. As a result of the study, 7 categories were derived: 'children who cannot protect themselves', 'childhood trauma,' 'insecure attachment and good child syndrome,' 'difficulties in interpersonal relationships,' 'difficulties in raising children,' 'somatization symptoms,' 'finding myself who is lost.' In addition, this study aims to understand the psychological experience of children in the family and the relationship between parents and children and the growth experience of healing them by comparing and contrasting the two cases of trauma. The foundation for healthy ego-resilience and emotional well-being has been laid through the research results on negative and maladaptive emotional experiences reflected throughout the life of adult women who suffered childhood trauma.

Objectives：This study was conducted to investigate the degree of psychopathologies of the family members of children with chronic convulsive disorder and evaluate the structures and dynamics of those families. Methods：The participant patients and family members were recruited from the population attending the outpatient clinic of department of pediatric neurology in Seoul National University Hospital in Korea. All the patients had idiopathic chronic convulsive disorder. Any patient with mental retardation, pervasive developmental disorder and gross brain pathology was excluded. As controls, normal students were chosen and their sex, age, achievement, socioeconomic status were matched to patients. The author interviewed the children and their family members twice and obtained informations about patient-parent relationship, patient-sibling relationship and others. For in-depth evaluation, we used family environment scales(FES), symptom Checklist-90-revised(SCL-90-R), self administered dependency questionnaire for mother(SADQ). Results：After interviewing with the parents of epileptic children, overprotection of parents, hostile feeling of siblings toward index children were higher than controls. The parental conflict was also more expressed than control families. According to results from FES, the scores of the subscales of expression, achievement-orientation, intelligence-orientation and active recreation were significantly lower than control group. The epileptic children showed higher dependency to parents especially in affection, communication and traveling areas of SADQ than control group. Maternal psychopathologies evaluated by SCL-90-R were much higher than the mothers of controls. According to T scores of SCL-90-R, about 40% of mothers with epileptic children had the risk of clinically significant depressive or anxiety disorders. Conclusion：These results suggested that the family members of epileptic children had more relationship problems and psychopathologies than control group and some mothers might have clinically significant depressive or anxiety disorders. so, effective psychiatric family interventions are needed for resolution of conflict and psychopathologies of family members.

The purpose of this study was to examine the associations of Korean older adults' use of Social Network Service (SNS) and text messages with frequency of contact with 1) non-coresident adult children, 2) siblings and relatives, or 3) friends, neighbors, and acquaintances. Data were drawn from the 2017 Survey of Living Conditions and Welfare Needs of Korean Older Persons 65+ (N=8,392), and older adults were categorized into 4 groups depending on their familiarity with use of SNS and text messages. Ordinary Least Squares regression models were estimated for analyses. Results revealed that older users of both types of communication media reported frequent exchanges of calls, text messages, etc. with both family and friends. However, using SNS and text messages was consistently related to more face-to-face contact with non-family members. To conclude, older adults' familiarity with communication media could be key to exchanges of emotional and instrumental support with informal social network members and quality of life in the community. Overall, our results highlight the importance of information communication education targeting older adults for continued involvement with their informal social network members.

Employment form and gender as stratification factors may generate health disparities in Korea. Previous studies have examined the existence of health disparities by employment form and gender. However, few studies examined how the health disparities can be reduced effectively. This study intends to confirm the existence of health disparities between employment-gender groups and explore the effective health resources which can reduce the possible disparities. Using a national probability sample of Korean adults collected in 2011, we attempts to test the interaction effects between employment-gender groups and health resources on self-rated health. For health resources, 24 variables of five dimensions(social relationship, psychological resource, activity factor, health behavior, and usage of medical service) are taken into account. In results, first, the health levels of the other three employment-gender groups are worse than that of male-regular workers. Second, the effective health resources which can reduce the health disparities are different across the employment-gender groups. An effective health resource for female-nonregular workers is a peaceful relationship with her children. Effective health resources for male-nonregular workers are peaceful relationships with his parents and siblings, low stress, religious activity, and exercise. An effective health resource for female-regular workers is interpersonal trust. These results imply that personal or social interventions for health of specific disadvantaged groups need to focus on specific resources which are more effective for the groups.

본 연구는 초등학교 5, 6학년 학생의 인터넷 중독과 학교생활 적응과의 관계를 파악하여 인터넷 사용에 대한 교육적 지도방안과 인터넷 중독 예방프로그램 개발의 기초 자료를 제공하고자 시도되었다. 자료는 2009년 7월 1일에서 7월 24일까지 제주특별자치도에 위치한 초등학교 6개교(동지역 4개교, 읍지역 2개교)를 무작위 추출하여 5, 6학년 학생 총 1195명을 대상으로 조사하였다. 자료 분석은 SPSSWIN(12.0 한글판) 프로그램을 이용하여 카이제곱검정, t-검정, 일원배치 분산분석, 상관분석, 다중회귀분석의 통계적 방법을 이용하였다. 본 연구의 주요 결과는 첫째, 대상자의 인터넷 중독 정도는 고위험군 55명(5.5%), 잠재적위험군 49명 (4.9%), 정상군 900명(89.6%)으로 나타났으며, 둘째, 대상자의 일반적 특성에 따른 인터넷 중독 정도를 분석한 결과 성별, 형제자매 유무, 학교성적에 따라 유의한 차이가 있었다. 셋째, 대상자의 컴퓨터 사용 특성에 따른 인터넷 중독 정도는 최초 인터넷 이용 시기, 인터넷 이용용도, 하루 인터넷 사용 시간, 부모컴퓨터 사용 여부에 따라 유의한 차이가 있었으며, 넷째, 인터넷 중독과 학교생활 적응과의 관계를 분석한 결과 학교생활 부적응인 경우는 '고위험군' 32명(58.2%), '잠재적위험군' 24명(50.0%), '정상군' 257명 (28.7%)으로 고위험군과 잠재적위험군이 정상군보다 학교생활 적응 정도가 낮은 것으로 조사되었다(p<0.01). 다섯째, 인터넷 중독에 유의한 영향을 주는 변수는 학교생활 적응 정도, 성별, 하루 인터넷 사용시간, 인터넷 이용용도, 인터넷 이용 상황, 어머니 직장 유무, 거주 지역, 부모 컴퓨터 사용여부, 최초 인터넷 이용시기이었다. 학교생활 적응 정도가 낮을 때, 남학생, 하루 인터넷 사용시간이 3시간 이상, 인터넷 이용 용도가 '게임', '스트레스가 쌓였을 때' 인터넷을 이용하는 경우, 어머니 직장이 있는 경우, 거주 지역이 동지역, 부모님이 컴퓨터를 사용할 줄 모르는 경우, 최초 인터넷 이용 시기가 취학 전인 경우가 인터넷 중독 점수가 높은 것으로 나타났다. 여섯째, 학교생활 적응에 유의한 영향을 주는 변수는 인터넷 중독 점수, 학교성적, 가정경제수준, 거주지역, 인터넷 이용용도, 학년이었다. 인터넷 중독 점수가 낮을수록, 학교성적이 높을수록, 가정경제수준이 잘 살수록, 거주지역이 동지역, 인터넷 이용용도가 '정보검색, 홈페이지관리/메신저', 5학년인 경우에 학교생활 적응을 더 잘하고 있는 것으로 나타났다. 이상의 결과를 종합해 보면, 학교생활 적응 정도가 낮을수록 인터넷 중독 점수가 높게 나타나고 있고, 인터넷 중독 경향이 높을수록 학교생활 적응 수준이 낮게 나타나고 있음을 알 수 있다. 아동들은 하루중 대부분의 시간을 학교에서 생활하고 있기 때문에 학교생활 적응은 아동들이 건전한 성인으로 성장하는데 중요한 요인이 된다. 또한, 인터넷사용률 증가와 최초 인터넷 이용 연령층이 점점 낮아지고 있음에 따라 인터넷 중독률이 자연스럽게 점점 높아질 것으로 예측되어진다. 따라서, 가정과 학교가 연계하여 아동들의 인터넷 사용에 대한 지속적인 관심과 지도가 필요하며, 인터넷 중독경향이 높은 아동들이 학교생활 적응을 잘할 수 있도록 인터넷 중독 치료 및 예방교육 프로그램 운영이 필요하다 하겠다.
