The study is to examine how facial EMG responses change when children experience a positive emotion(happiness) and a negative emotion(fear). It is to prove that the positive emotion(happiness) could be distinguishable from the negative emotion(fear) by the EMG responses. Audiovisual film clips were used for evoking the positive emotion(happiness) and the negative emotion(fear). 47 children (11-13 years old, 23 boys and 24 girls) participated in the study Facial EMG (right corrugator and orbicularis oris) was measured while children were experiencing the positive or negative emotion. Emotional assessment scale was used for measuring children's psychological responses. It showed more than $85\%$ appropriateness and 3.15, 4.04 effectiveness (5 scale) for happiness and fear, respectively. Facial EMG responses were significantly different between a resting state and a emotional state both in happiness and in fear (p<001). Result suggests that each emotion was distinguishable by corrugator and orbicularis oris responses. Specifically, corrugator was more activated in the positive emotion(happiness) than in the negative emotion(fear), whereas orbicularis oris was more activated in the negative emotion(fear) than in the positive emotion(fear).

In evaluating the ride comfort of railway vehicles, relationship between passenger's feeling and vibration characteristics is very important because human feeling is dependent on frequency spectrum of vibration. Therefore, the weighing curves in frequency domain are used to evaluate the ride comfort of railway vehicles. These curves have been defined in the Laplace transfer functions. It is necessary to convert the Laplace weighing function to the z weighing function in order to obtain the rms value in the time domain. In the present paper, we have applied Tustin's approximation to transform the Laplace weighing function to the z weighing and validated this method by reviewing the various cases.

최근 자연어 처리 분야에서 문맥적 의미를 반영하기 위한 대조학습 (contrastive learning) 에 대한 연구가 활발히 이뤄지고 있다. 이 때 대조학습을 위한 양질의 학습 (training) 데이터와 검증 (validation) 데이터를 이용하는 것이 중요하다. 그러나 한국어의 경우 대다수의 데이터셋이 영어로 된 데이터를 한국어로 기계 번역하여 검토 후 제공되는 데이터셋 밖에 존재하지 않는다. 이는 기계번역의 성능에 의존하는 단점을 갖고 있다. 본 논문에서는 한국어 리뷰 데이터로 임베딩의 의미 반영 정도를 측정할 수 있는 간단한 검증 데이터셋 구축 방법을 제안하고, 이를 활용한 데이터셋인 SimKoR (Similarity Korean Review dataset) 을 제안한다. 제안하는 검증 데이터셋을 이용해서 대조학습을 수행하고 효과성을 보인다.

Recently, an interest on how to moderate parenting stress of grandparents is rising according to rising depression of grandparents of grandparents and grandchildren family(GGF) because of parenting stress So, this study tried to analyze moderating effects by setting social support and stress coping behaviors as moderator variable in order to know how much parenting stress of grandparents would influence their depression. For this purpose, we selected 369 cases of grandparents who were being provided social welfare service and to 334 cases out of them, did multigroup analysis using hierarchical regression analysis and structural equation model under spss Vor. 19.0 program. Followings are the results. First, the more parenting stress was high, the more depression high. But when social support was high, parenting stress low. And the more parenting stress was high, faith dependence, negative emotional expression and passive evasion as stress coping behaviors also high while problem reestablishment low. Second, emotional support, information support, and material support as social support had moderating effects in which parenting stress influenced depression while appraisal support had not. Third, faith dependence and low passive evasion as stress coping behaviors had moderating effects in influence of parenting stress to depression while problem reestablishment has not. On the one hand, emotional expression was meaningless in explaining moderating effects in connection with parenting stress. Through these, we draw a social welfare practical implication that could lift moderating effect of social support and stress coping behavior in between parenting stress and depression of grandparents of grandparents and grandchildren Family.

향은 방향성 또는 휘발성 물질에 il해 코의 점막을 통해 흡입되어 여러 감성의 변화와 뇌파등 생체 신호의 변화를 초래하고 또한 풍부한 감성도 유발한다. 특히 기억력에 관련된 원시 감정을 유발하고 생체에서 나오는 phermone(페르몬)은 행동 양식까지 영향을 미친다. 또한 질환치료에도 적용되거나 증상의 경감, 예방효과 등을 보여주는 aromatherapy는 매우 유망한 분야이다. 본 연구에서는 이러한 페르몬 향과 aromatherapy에 사용되는 essential oil등을 이용하여 주관적 감성 평가를 실시하고 이를 통계분석하여 이들 여러 종류의 향들의 자극으로 유발되는 감성의 특징을 밝혀내고자 하였다. 둘째로 향의 선호도를 결정하는데 어떠한 감성요인이 작용하는지를 알고자 하였다. 실험에 사용된 향은 26종류이고 총 33명의 지원자가 참여하였다. 설문지는 18문항을 선별하여 4가지 유형으로 작성한 후 유형별로 데이타를 정리하여 베리막스의 요인분석, 회귀분석, 군집분석등을 이용하여 분석하였다. 베리 막스의 요인분석으로 감성 형용사를 비슷한 척도끼리 묶어 .괘한 감성을 결정하는 요인, 자극의 강도를 결정하는 요인, 이외의 다른 고풍스럽거나 현대적인 요인등 3개 요인으로 grouping하였다. 향의 선호도를 결정하는데 중요한 감성척도에서는 피검자 성별에 따라 차이가 있음을 보여주었다. 남성의 경우 황홀하다, 여성적이다인데 반해 여성인 경우 재적하다, 친숙하다라는 감성 척도가 중요하게 작용하였다. 또한 각 향별로 군집 분류하여 향의 종류를 구분할 수 있었으며 또한 각 향별 선호도를 결정하는 감성 척도도 구해 보았다. 또한 향의 분류에 따른 감성 척도의 특징을 성별로 관찰한 결과 페르몬 향인 경우 essential oil과 달리 성별의 차이가 나타났다. 결론적으로 후각을 자극하는 향물질로 유발된 감성 측정을 해 본 결과 성별에 따라 선호도를 결정하는 감성요인의 차이를 알 수 있었으며 또한 essential oil에서는 성별 차이가 없는데 반해 페르몬 향의 경우 성별의 차이를 나타내었다.

Temporomandibular disorder(TMD) is relatively prevalent disease, and quality of life may be impaired in TMD patients. Like general population, dental hospital workers are also exposed to the risk of TMD. But, many of them tend to overlook or tolerate their symptoms for lack of time and interest. Therefore, problems may become more serious, causing interference of performing task and decrease of quality of life. The aim of this study were to obtain data for TMD prevalence in dental hospital workers and to evaluate quality of life according to TMD symptoms. Subjects were recruited from Wonkwang University Dental Hospital. After consent, subjects completed quality of life questionnaire and were evaluated for subjective and objective signs and symptoms of TMD. Subjects were classified into 4 groups : (1) normal group (2) joint disorder group, (3) local myalgia group, and (4) myofascial pain group. The result of the study indicated that TMD negatively influences the quality of life in dental hospital worker. TMD symptoms can deteriorate quality of life in dental hospital worker. Future effort to make protocol for proper management is needed.
