An opinion mining technique which was developed from document classification in area of data mining now becomes a common interest in domestic as well as international industries. The core of opinion mining is to decide precisely whether an opinion document is a positive or negative one. Although many related approaches have been previously proposed, a classification accuracy was not satisfiable enough to applying them in practical applications. A opinion documents written in Korean are not easy to determine a polarity automatically because they often include various and ungrammatical words in expressing subjective opinions. Proposed in this paper is a new approach of classification of opinion documents, which considers only a frequency of word patterns and excludes the grammatical factors as much as possible. In proposed method, we express a document into a bag of words and then apply a learning algorithm using a frequency of word patterns, and finally decide the polarity of the document using a score function. Additionally, we also present the experiment results for evaluating the accuracy of the proposed method.

Our aims is a exploration for relationship between father and male-adolescence. For this purpose, we have employed several self-reported questionnaires, including BDI, Rosenberg self-esteem scale, Attitude for father etc. Our hypothesis is that the perception, the attachment, age and alcohol drinking, accademic career of father influences male-adolescent's self-esteem, mood, sex-role, academic accomplishment, satisfying of school life. We have surveyed questionnaire at one middle school, at Suwon city. We have get 196 samples. We have categorized subjective answers and analyzed relations. The result is that a positive relation is self-esteem, sex-role, and attachment, a neagtive relation is mood and no relation is age, academic career, alcohol drinking. Also, father's overprotection attribute on negative influences. We have many limitations. First limitation is a small number. Second is few previous study. Third is a relative analysis, not cause-effect analysis.

This study examined consumers' perceived anxiety regarding how safe the clothing and lifestyle products are as well as influencing factors. Data was collected using a self-ministered online survey of 1,126 adult consumers. The results of this study showed that consumer anxiety about chemicals and hygiene product safety had a greater impact on the anxiety perception of general safety than clothing and beauty products. It was confirmed that the reliability of information source (government agency, mass media, expert group, and internet community/blog) varies depending on the level of consumers' overall safety anxiety. The study also found the effect of consumers' subjective perception of health on safety anxiety about clothing and lifestyle products. Further, the moderating effect of age in the research model was confirmed. This result can be a useful guide to marketing communication for developing consumer safety-related policies to reduce consumer anxiety. The information will also help consumers make informed decisions that lead to safe and sustainable consumption.

Objectives : This study looked at the relationship between occupational stress and the Oral Health Impact Profile (OHIP), to evaluate the effect of occupational stress-related factors. Methods : Data was obtained from a cross-sectional survey of 260 local officials in Gangwondo. The research comprised three questions relating to subjective oral symptoms, an occupational stress measurement tool and an oral health impact factor which was composed of questions. The data was analysed using t-test, one-way ANOVA, Pearson correlation and path analysis in Amos. Results : Occupational stress had a positive correlation to drinking frequency, Oral symptoms had a negative correlation. And drinking frequency, smoking amount and occupational stress had a positive correlation to oral symptoms. It denoted that drinking frequency, occupational stress and oral symptoms had a negative correlation to OHIP. The path model had an excellent goodness of fit (p=0.07, namely p>0.05). Five 'goodness-of-fit indices' of the model were all above 0.9: GFI=0.987, AGFI=0.952, NFI=0.902, IFI=0.939, CFI=0.934), and its RMSEA was 0.045. Occupational stress and oral symptoms had a firsthand impact on OHIP. In addition, it affected OHIP through the parameters of oral symptoms. Occupational stress exercised a firsthand influence on drinking frequency, drinking frequency exercised a firsthand influence on smoking amount. Smoking amount had a firsthand impact on oral symptoms. Conclusions: Oral health education programs for the development of an improved oral hygiene environment through reduction in drinking and smoking also need to focus on relieving stress by improving workplace culture. In addition, due to good communication is required to reduce occupational stress caused by interpersonal conflict.

The single-item question of self-assessed health status has consistently been reported to be associated with mortality in some developed countries, even after controlling for a wide range of health measurements and known risk factors for. mortality. It was intended in this study to find out whether or not such a relationship would also be valid in Korea. This study examined the effect of point of reference year on. the, predictive validity of self-assessed health for mortality in 6-year follow-up period. we need to test the validity of the self-assessed health, as an indicator for assessing health status using Cox's proportional hazard model. For the analysis, we used the data from the 2nd (1999) to the 7th survey of "Korean Labor and Income Panel Study," and assessed relative risk of death based on subjective health state by tracing 11,366 people who replied to the question of self-assessed health state in the 2nd year. According to the result, those who reported poor self assessed health state in the 2nd year showed a relatively high death rate, and their relative risk of death was significantly higher. Such a relationship was accentuated if the predictive value of the 2nd survey result would be replaced by the average of the cumulative data on the past six years. Thus, it can be concluded that self-assessed health state is valid as an index for assessing Korean people's health status.

Objective and subjective methods were performed together for TPA analysis of acorn mook, and their correlations were analyzed. As the result of sensory evaluation, hardness and fracturability were most important factors for prediction of preference. Meanwhile, compression test with Instron Universal Testing Machine revealed that P1(maximum peak in first bite) was very effective factor representing the cheracteristics of first bite, and that P2 the latter peak in first bite) was valuable for prediction of characteristics of second bite.

This paper describes a Q-methodological study on the Perception of comfort in hospital in-patients. The participants completed a 37-item Q sort made up of statements which could be ranked in terms of their relevance to the subjective meaning of comfort. Three interpretable types of comfort were identified through this Q study : Type I, positive medical action style, feel secure and satisfied when medical staff show a positive attitude towards them as patients. They put a high value on prompt responses from medical staff and physical aspects of care like non-invasive procedures or comfortable position. Type II, social relation style, experience a state of comfort when they perceive support or concern from medical staff, relatives or other patients suffering from similar diseases. They feel safe and secure when medical staff are kind and have a good reputation or when the size of the hospital is big enough, Type III, emotional wellbeing style, feel that hope for a healthy life or maintaining self-care activities are highly valuable. They feel safe and comfortable when their privacy is protected. They put worth on independent thinking, strong will, and emotional or psychological comfort. The results of this study can be used as a basis to develop nursing measures for comfort. Further studies on factors which influence perception of comfort and intervention strategies according to the above types of comfort need to be done.

Purpose: This study was conducted to improve the working conditions of dental technicians, through survey for working conditions related to perform one's duty, the extent of personal exposure to substances hazardous and complaint rate and factor of job stress and subjective symptom on musculoskeletal disorders. Methods: Using four types of structured questionnaires: social and demographic factor; the actual conditions of working space; working conditions; and characteristics of dental technicians, respondents filled in the questionnaires and the results were analyzed statistically. Results: The evaluation of comfort in working place found that satisfaction level on indoor noise was the lowest with 2.6 on a five-point scale and privacy space followed 2.8 point. In reasons for dissatisfaction with job, over workload ranked the highest by 25.4% and role overload had the highest by 39.5% in job stress factors. Based on the results, we could draw conclusion that dental technicians were unsatisfied with role overload and heavy workload a day. In reasons for musculoskeletal symptom prevalence, long-patient work was the highest by 24.1%. It was thought to cause dental technicians need deep procession and long-patient work due to the nature of their job. Conclusion: In conclusion, noise reduction and privacy space are required to improve job efficiency of dental technicians. In addition; we need to think of ways to increase the job satisfaction with adequate rest while deep procession and long-patient working.

The literature on parent-child relationships in young adulthood lacks a systemic approach that considers the multifaceted nature of intergenerational relationships. In this paper, we identify the latent profiles of young Korean adults' relationships with their parents based on the six dimensions of intergenerational solidarity (structural, associational, affectual, consensual, functional, and normative solidarity) as indicators. We considered solidarity for the mother and the father separately for structural, associational, affectual, and consensual dimensions. In terms of functional and normative solidarity, we measured both upstream and downstream intergenerational support. The sample included 1,015 young adults who were 19-34 years old, never married, not in secondary school, and had both parents living. The latent profile analysis revealed four profiles: (a) independent but intimate (22.7%), (b) coresident, outwardly intimate (32.4%), (c) detached from father (6.7%), and (d) coresident, intimate (38.2%). The factors that predicted each profile included the young adults' education, income, subjective socioeconomic status, and experiencing the features of emerging adulthood along with the parents' marital status, father's employment, and overparenting. The "coresident, intimate" group reported significantly higher levels of life satisfaction and fewer depressive symptoms compared to the other three groups. The lowest levels of psychological adjustment were found in the "coresident, outwardly intimate" group and "detached from father" group.

The style of a dress allows important characterization of an era since they reflect contemporary politics, society, culture and arts. Within a same category, period costumes develop into styles that reflect specific consciousness. The research method and the scope of the study are as follows: the research adopts a historical study method and a comparative research from a microscopic point. The scope includes resistance costumes that proceed with sans-culotte that comprises of the resistance party during the 18th French Revolution (1783-1799), and also a Hippy style which was popularized during the 1960s and 1970s for its anti-war movement. We researched both similarities and differences of design factors reflecting resisting consciousness in costumes that affected costume characteristics related to their socio-cultural background. Sans-culotte and the Hippie style reflect a common denominator in anti-social resisting customs. First, they show common characteristics that combine fashion trends of resistant element and design features. Second, they have common features which are the characteristics of deviation. On the other hand, these two customs also present a discriminative denominator in anti-social resisting customs. In the case of sans-culotte, they tend to symbolize confrontation by dividing into two equal parts: the old and new mode. Sans-culotte confronts the conventional mode and promotes practical costume styles based on justice standpoints. First, hippies pursue an exposition of individual emotions that disclose internal meanings of love and desire. Second, they focus on subjective characteristics and chase after masteries and pleasures by expressing intensity. Third, it extends and develops folk costumes from many countries that reveal ethnic trends. Therefore, this research compares and contrasts different changes in the fashions of revolutionary periods, and aims to recognize the relationship between design and costume characteristics, thus contributing to the predictions of future changes in fashion.
