BACKGROUND/OBJECTIVES: The objective of this study was to examine factors affecting cooking behavior at home. We examined components of the theory of planned behavior, perception of cooking skills, and socio-demographic variables affecting cooking behavior at home. SUBJECTS/METHODS: The study sample included 425 women raising elementary school children living in South Korea. They responded to an online structured questionnaire. The variables affecting cooking behavior at home were assessed using hierarchical regression analysis. RESULTS: The frequency of cooking behavior at home was 14.1 meals per week. Most respondents showed an intention regarding cooking behavior. The average score for attitude toward cooking behavior at home was 15.1 points (scale of 1 to 25). Attitude and cooking behavior showed a significant positive correlation (P < 0.01, r = 0.22). The subjective norm was 14.6 points (scale of 1 to 25). The subjective norm showed a significant correlation with cooking behavior (P < 0.01, r = 0.18). The control belief was 2.8 points (scale of 1 to 5). The control belief and cooking behavior showed a significant correlation in all questions (P < 0.01, r = 0.25). The subjects were significant confident about their cooking skills, except for Kimchi. Perception of cooking skills showed a significant correlation with all questions concerning cooking behavior (P < 0.01, r = 0.30). Significant variables for predicting intention regarding cooking behavior were perception of cooking skills, employment status, income, and attitude. Significant variables for predicting cooking behavior were employment status, income, control belief, number of children, and behavioral intention. CONCLUSIONS: In order to provide nutrition education to increase cooking behavior at home, it is necessary to have a positive attitude toward cooking behavior, increase control belief, and improve confidence related to cooking skills. Moreover, differentiated education based on the employment status of women is needed.

Conventional time-scale modification methods have the problem that as the modification rate gets higher the time-scale modified speech signal becomes less intelligible, because they ignore the effect of articulation rate on speech characteristics. Results of research on speech perception show that the timing information of transient portions of a speech signal plays an important role in discriminating among different speech sounds. Inspired by this fact, we propose a novel scheme for modifying the time-scale of speech. In the proposed scheme, the timing information of the transient portions of speech is preserved, while the steady portions of speech are compressed or expanded somewhat excessively for maintaining overall time-scale change. In order to identify the transient and steady portions of a speech signal, we employ a simple method using LPC cepstral distance between neighboring frames. The result of the subjective preference test indicates that the proposed method produces performance superior to that of the conventional SOLA method, especially for very fast playback case.

본 연구의 목적은 어머니의 자기지각 성향과 자녀 문제에 대한 지각 성향간의 관계를 규명하는 것이다. 소아 정신과를 방문한 아동 62명을 대상으로 어머니의 다면적 인성검사(MMPI)의 타당도 척도와 그 어머니가 보고한 자녀의 한국아동인성검사(KPI-C)의 타당도 척도간의 상관을 구하였고 t-test를 통해 KPI-C 세 타당도 척도(T-R, L, F) 각각에서 MMPI 타당도 척도 각각의 상·하위 집단간에 차이가 있는지를 알아 보았다. MMPI의 K 척도와 KPI-C의 거짓말(L) 척도간에 유의한 정적상관, MMPI의 F 척도와 KPI-C의 L 척도간에 유의한 부적상관을 보였다. t-test결과, KPI-C의 L 척도는 MMPI의 F, K 척도의 상 ${\cdot}$ 하위집단간에 유의한 차이를 보였고 KPI-C의 F 척도는 MMPI L 척도의 상 ${\cdot}$ 하위 집단간에 유의한 차이를 보였다. 즉, 자신의 심리적인 문제에 대해 정교한 방어기제를 사용하는 어머니가 자녀의 심리적인 문제에 대해서도 방어적으로 지각하는 성향이 있는 반면, 자신의 문제를 고통스럽고 과장되게 지각하는 어머니는 자녀의 심리적인 문제에 대해서 과장되게 지각하지는 않음이 시사되었다. 또한 자신의 심리적인 문제를 부인하고 단순한 방어기제를 사용하는 어머니는 자녀의 문제에 대해서는 그 정도를 심각하게 지각하지 않음이 드러났다. 따라서 본 연구결과는 MMPI 타당도 척도 중에서 무엇보다도 K 척도가 상승하는 어머니가 자녀의 문제를 과소평가할 가능성이 있다는 것을 감안하여 그러한 어머니가 보고한 자녀문제의 심각도와 내용을 신중하게 평가하여야 할 것을 시사한다.의 효과에 대해 비교했을 때 품행장애가 공존된 집단에서 치료전에 비해서 아동행동조사표의 문제행동목록 중 공격성 요인에서 유의한 감소(p<.05)가 보였으며, 사회적 능력 항목중 활동성과 사회성에서 유의한 차이(p<.0001)를 보였다. 지능저하등 다른질환군이 동반된 군에서는 사회기술 평가 척도의 사회기술 항목에서 유의한 증가(p<.05)를 보였다. 그러나 각 집단간의 치료효과에 대해서는 세 집단사이에서 유의한 차이는 보이지 않았다. 위 결과로 보아 주의력결핍 과잉운동장애 아동에서 사회기술훈련 치료프로그램은 통계적으로 유의미할 만한 사회기술 향상은 보이지 않았다. 반면 품행장애가 동반된 군에서 공격적 행동의 감소를 가져오고 인지능력이 떨어진 군에서 사회기술 호전을 보이는 등 아동의 특성 및 동반증상에 따라 사회기술의 호전 및 증상의 변화에 도움이 됨을 확인할 수 있었다. 문제이며, 이것을 예방하고 치료하기 위해서는 우리 의사들의 적극적 관심이 필요하다고 생각하였다.)에서 자기파괴적인 행동이 있었으며 46명(29.3%)에서 충동성이 동반되었고 35명(22.3%)에서 유뇨증이 관찰되었다. 환자의 발병연령과 내원시 연령, 병의 이병 기간, 강박증상의 정도 사이에 통계적으로 유의한 양성의 상관관계가 있었고 과잉행동성과 음성의 상관관계가 있었다. 과잉행동성과 충동성, 강박성, 야뇨증, 자기파괴적 행동사이에 통계적으로 유의한 양성의 상관관계가 있었다. 환자의 강박증상의 정도와 과잉행동성, 수면장애, 자기파괴적 행동 사이에 통계적으로 유의한 양성의 상관관계가 있었다. 본 연구 결과 저자들은 외래에 내원한 뚜렛장애 환자의 임상적 특성이나 동반된 행동상 문제들이 이전 연구와 크게 상이하지 않음을

Human perceptional speed is different from its real speed. There is lack of research that the perceptional speed is different from real speed in 2-dimension, because most research of speed perception has concentrated on points and lines. This research investigates the effects of object size on speed perception. In this research, we used 2-D circular objects of the different size, 0.9, 1.8 and $3.6^{\circ}$. The objects moved 9.0, 13.5 and $18.0^{\circ}$ with three different speeds, 6.0, 9.0 and $18.0^{\circ}$/s. Six participants were exposed to the environment with standard scene(size: $1.8^{\circ}$, speed: $9.0^{\circ}$/s and travel distance: $13.5^{\circ}$). After the first scene, another scene in which the object had changed to different sizes, speeds and distances, was shown to the participants. A magnitude estimation method was used to construct a scale of the perceived speed level. The relationship between the perceived and the actual speed level was explained by Stevens's power law that the value was 0.978 with the exponent of 0.992. The size of object had an effect on the speed perception but travel distance was not. The perceptional speed of bigger object was lower than of smaller object. It showed that the degrees of perceptional speed decreased as size of object increased.

Discussions on sustainability in the fashion industry highlight the need for a holistic and strategic approach. This study investigated consumers' perception of fashion companies' sustainability and its relationship with value and perceived consumer effectiveness as well as with consumer trust, preference, and purchase intention. The assessment scale of fashion companies' sustainability was developed for this study and data were obtained from 645 consumers in their 20's to 60's in Korea. As a result, consumers' value and perceived consumer effectiveness had significant effects on consumers' perception of fashion companies' sustainability. Universalism, security/benevolence and perceived consumer effectiveness were variables that had significant effects on all four dimensions of sustainability. Consumer's perception of fashion companies' sustainability significantly influenced consumer trust, preference and purchase intention. Especially, environmental, societal, and cultural sustainability (rather than economic dimension) were shown to have a greater impact on consumers' trust, preference and purchase intention.

Purpose - The study verified the effects of consumers' knowledge perception upon word-of-mouth intention and purchase intention of consumers who were exposed to a lot of information, and examined consumer's behavior from multi-dimensional points of view. Research design, data, and methodology - The study conducted the test of difference between consumer's cognition on importance and satisfaction of HMR product by gap of HMR (Home Meal Replacement) product for IPA analysis. The consumer's reliability and words-of-mouth were measured by the questionnaire method with 4 questions according to Likert 7-point scale. Conversion into z-score removed the difference of variables. Results - The causal relation model for importance, satisfaction and gap, not relying upon multi-dimensional scaling and others, could construct causal relation model to give implications. Difference (d) of the products could lessen consumer's reliability to increase consumer's knowledge perception, word-of-mouth intention, knowledge perception, and purchase intention. Therefore, enterprises should make an effort to lessen consumers' complaint for the products and to elevate consumers' reliability. Enterprises also try to give consumers exact information and to promote purchase intention. Conclusions - Difference (d) of consumers' complaint and/or disappointment decreased consumers' reliability to increase knowledge perception. Enterprises should supply consumers with products according to their requirements to minimize the gap and to give them proper information.

The purpose of this study was to investigate the relation between perception of family environment and mental health of boy's high school students. In order to obtain the appropriate data, a questionnaire was administered to 240 boy's high school 2nd-grade students in Pohang city from March 19 to March 28, 1992. The instruments used for this study were Moos's Family Environment Scale Form R and Kim's Symptom Check List-90. The conclusions were as follows : The level of perception of family environment was lower than mean score. Cohesion, achievement orientation, independence, organization, expressiveness were percepted high but active-recreational orientation, intellectual-cultural orientation were percepted low. Mental health of most respondents was well. The scores of obsessive-compulsive reaction and interpersonal sensitivity were high, the scores of somatization and phobia were low. General characteristic variables significantly related to the level of perception about family environment were father's occupation and mother's education level. There were no significant differences between general characteristic variables and mental health. There were mostly negative correlations between perception of family environment and mental health. Cohesion, expressiveness, independence, intellectual-cultural orientation, active-recerational orientation, moral-religious emphasis, organization were negatively correlated but conflict, achivement orientation, control were positively correlated. Cohesion, expressiveness, conflict, achivement orientation, active-recretional orientation, organization, control were significantly related, but independence intellectual-cultural orientation, moral-religious emphasis were no significant correlation.

Purpose: The study investigated the perception, report, and education of elder abuse in 119 emergency medical technicians (EMTs) in Korea. Methods: A self-reported questionnaire was distributed to 110 EMTs in K city, and 100 answers were collected from June 1 to 10, 2015. The study instrument was perception regarding elder abuse and education inventory developed by Kim and Kim. Data were analyzed using SPSS/WIN 18.0 version. Results: The elder abuse perception score was 3.81 on a Likert 4-point scale. Physical abuse was the most common type, followed by verbal, financial, negligence, and emotional abuse. Most EMTs recognized that is important for the prevention of elder abuse, but most of them had no experience in reporting abuse. A majority of the EMTs had attended an elder abuse program and recognized the importsnce of such program. Conclusion: This study suggests the necessity of more targeted education of elder abuse prevention combined with family counseling methods and practical approach toward awareness of elder abuse.
