기존의 연구는 DNA 커널을 통한 기계 학습이 DNA 분자들을 통한 in vitro 실험을 통해 가능함을 보였다. 이 때, DNA 커널을 통한 분류 분제는 온도 조절을 통해 양한정(positive definite) 조건을 만족시킬 때 분류 문제를 잘 풀며, 양한정 조건을 만족시키기 위한 조건으로 높은 온도에서 시작하여 온도를 내리며 hybridization시키는 방법을 제안하였다. 이 논문에서는 보다 정량적인 분석을 통해서 이 hybridization 방법이 양한정 조건을 만족시키기에 적합한 방법임을 보이고, 간단한 hybridization 모델을 통해 양한정 조건을 만족시킬 수 있는 hybridization 온도 계획의 충분 조건을 유도한다. 또한 시작 온도와 끝 온도의 경계 조건으로 제시되는 이 충분 조건을 통해 현실적인 온도 조절 계획을 위한 시퀀스의 코딩 방법을 알게 된다.

Do happy applicants achieve more? Although it is well established that happiness predicts desirable work-related outcomes, previous findings were primarily obtained in social settings. In this study, we extended the scope of the "happiness premium" effect to the artificial intelligence (AI) context. Specifically, we examined whether an applicant's happiness signal captured using an AI system effectively predicts his/her objective performance. Data from 3,609 job applicants showed that verbally expressed happiness (frequency of positive words) during an AI interview predicts cognitive task scores, and this tendency was more pronounced among women than men. However, facially expressed happiness (frequency of smiling) recorded using AI could not predict the performance. Thus, when AI is involved in a hiring process, verbal rather than the facial cues of happiness provide a more valid marker for applicants' hiring chances.

Dealing with existential concerns experienced by patients is an important part of palliative care. Interventions that use the life review method to encourage patients to reminisce about their lives can help them find new positive meanings, promote ego integrity, and reduce emotional suffering. Not everyone has positive memories when they look back on the past, however. This poses a limit on the effectiveness of the life review method for healthcare providers working in palliative care contexts. In this study, we discuss the limits of life review and suggest imagery rescripting as a new modality constituting a psychotherapeutic approach to deal with negative memories safely and effectively.

Measuring and evaluation of audience's visual message perception are crucial process for scientific production of visual content. This study tried to evaluate the difference of viewer's awareness of visual object depends on his or her inherent characteristics like conservatism using an eye tracker system. Especially, this experiment tested research questions about positive correlation between conservatism and peoples' eye movements following the sound visual messages. 57 subjects participated in the test. Two different groups were exposed to two visual elements representing 'the conservative' and 'the liberal'. The results showed that people tended to have different way of seeing visual objects according to their inherent characteristics. Also by comparing the gaze time at the object and area of interest(AOI) in visual, this study is able to verify the existence of 'positive way of seeing' and 'negative way of seeing'. The two different ways of seeing have their own trail of eye movement.

EEG(electroencephalogram) is characterized with auditory emotion in this study. Twenty university students participated in this study. The auditory stimulus was the natural sounds such as creek sound, clash, machining noise, and etc. They can cause the positive and negative emotion. EEG characteristics according to positive and negative auditory stimuli is tried to observe statistic difference. The significant difference is shown depending on the localized area. The auditory paraameters of EEG variation is examined for defining human emotion qualitatively. The results shows that the alpha and the beta at temproal area may be thd determinat of human auditory emotion.

In order to create humanitarian living environment with sustainable ecological environment, urban regeneration project has been implemented recently seeking diverse methods for residents'participation stressing the process of communication with the residents changing from the existing one way planning by limited number of experts. Particularly, it is essential to develop systematic tools to promote the voluntary and positive participation of the residents because residents have to perform as the master of urban streetscape design project that requires sophisticated knowledge and experience and also because the residents have to function as sustainable maintainers and managers of their streetscape. This study intends to identify the organizational structure and major contents of design guideline as a tool to support the voluntary and positive participation of the residents in streetscape maintenance. For this purpose based on the structural system and characteristics of Chicago streetscape design guideline that was developed as tool for residents' participation, efforts were made to set up framework of design guideline for sustainable streetscape project with the users' participation with their overall understanding and trust. In detail, the author studied the resident participatory process for sustainable maintenance and management in a long term landscape project and the principle and theories of design planning for streetscape that supports the utilizing behaviors of the users, and how this information should be linked and organized to form the structure and contents of design guideline. As a tool supporting residents' participation and helping the residents perform the responsible function as sustainable maintainers and managers of their streetscape through social maturity with ontological sense of masters of their local community as they experience the gradual processes of their streetscape maintenance project, streetscape design guideline has its meaning in the efforts that tried to achieve deep participation of the residents through researches converging the two academic sectors of urban architecture and social psychology.

This thesis intends to make a study on the effectiveness of Nursing Professors through perceptual psychological approach. Purpose of the Study Researches have been made relating teacher′s effectiveness measurement. However, they share a common defect that they have been done on the basis of superficial aspects of the problems aspects that can bi measured by general objective survey only, but this study is designed "to understand his behavior in terms of a human behaving and of a self as an instrument"-principle, based upon the Perceptual Psychology which puts more stress on the inner perception than on the external one. Method of the Study This thesis is based chiefly on the two sources : "Perceptual Orientation Scale"(Chunghoon Choy, 1971) which has been standardized on the basis of perceptual psychology and the question acres made by the researcher of this thesis and given to the 34 Nursing Professors in seoul and other country. Result of the Study The method of data operation by Pearson "r" asserts that there were distinct deep relation Between Perceptual orientation and fellow′s estimate, while a little relation among the estimate of a-administration, educational backgrounds and occupations but no relations the status of experiences. It can be concluded that the estimates between fellows working at "the same fields" have kept deep relations together on perceptual orientation which resulted from finding out a useful method to measure occupational effectiveness according to the perceptual field. Conclusion of the Study The personnel administration has been managed according to external flatus and not positive operation: on the other hand, this study holds, It shall be operated in accordance with the estimates by fellow, the "Preceptual Orientation Scale" for more positive ability. The study requires the following researches on the devoted professional occupations, such as medical doctors, teachers, nurses, etc. for the purpose of increasing their occupational effectiveness more scientifically.

The process model of emotion regulation suggests that cognitive reappraisal and expressive suppression engage at different time points in the regulation process. Although multiple brain regions and networks have been identified for each strategy, no articles have explored changes in network characteristics or network connectivity over time. The present study examined (a) the whole-brain network and six other resting-state networks, (b) their modularity and global efficiency, which is an index of the efficiency of information exchange across the network, (c) the degree and betweenness centrality for 160 brain regions to identify the hub nodes with the most control over the entire network, and (d) the intra-network and inter-network functional connectivity (FC). Such investigations were performed using a traditional large-scale FC analysis and a relatively recent sliding window correlation analysis. The results showed that the right inferior orbitofrontal cortex was the hub region of the whole-brain network for both strategies. The present findings of temporally altering functional activity of the networks revealed that the default mode network (DMN) activated at the early stage of reappraisal, followed by the task-positive networks (cingulo-opercular network and fronto-parietal network), emotion-processing networks (the cerebellar network and DMN), and sensorimotor network (SMN) that activated at the early stage of suppression, followed by the greater recruitment of task-positive networks and their functional connection with the emotional response-related networks (SMN and occipital network). This is the first study that provides neuroimaging evidence supporting the process model of emotion regulation by revealing the temporally varying network efficiency and intra- and inter-network functional connections of reappraisal and suppression.

This study examined the effects of emotional content on the encoding process of emotional stimuli and the effects of emotional context on those of neutral stimuli. It was examined whether the superior memory of emotional stimuli is due to attentional resource allocation. This study were performed an emotional picture and a neutral word were presented in succession at every trials. The results of recognition judgement showed superior memory of emotional pictures than neutral pictures, but showed poorer memory of neutral words in emotional context than those in neutral context. LPC(Late Positive Complex) of ERP results showed the similar pattern: higher amplitude by emotional pictures than neutral pictures, and lower amplitude by neutral words in emotional context than those in neutral context. This result is considered to support attention allocation hypothesis.

We surveyed the emotional images of three kinds of scientific technologies in people's mind and the perception of technologies in terms of their risks and benefits. The contents of the image and their image values were used to estimate the affects on each technology. As an affect heuristic hypothesis predicted, people perceived the technology more beneficial or riskier depending on their overall affect. In other words, those who have positive affect on the technology Perceived less risky and more beneficial than those who have negative affect. On the other hand, those who have negative affect on the technology perceived riskier and less beneficial than those who have positive affect. We also found negative relationship between the perceived risk and perceived benefit of each technology. The implications of our findings that suggest affective heuristic were discussed in terms of the measurements of affect and the necessity of communication of scientific technologies with the public.
