  • Objectives : Type D personality was originally introduced to study the role of personality in predicting outcomes of heart disease. However, researches showed that other medical conditions are also affected by this personality. The purpose of this study was to evaluate the relationship between type D personality and somatic symptom complaints in depressive patients. Methods : Eighty-two individuals diagnosed with depressive disorder were included. Type D personality was measured with DS14. Patient Health Questionnaire(PHQ) 9 and 15 were used to measure depression severity and somatization tendencies. For alexithymia, TAS-20 was used. Student T-test and linear regression analysis were performed. The best regression model was determined by stepwise variable selection. Results : More than half of the subjects(56%) complained at least medium degree somatic symptoms according to PHQ-15 criteria. Two-thirds of the subjects were classified as Type D personality(63.4%). The mean PHQ-15 score of the Type D individuals was significantly higher than the remaining subjects(PHQ-15 mean=12.7, $p=8.2{\times}10^{-7}$). The best regression model included age, PHQ-9 score and NA subscale score as predictor variables. Among these, only the coefficients of age($p=1.5{\times}10^{-3}$) and NA score($p=1.5{\times}10^{-7}$) were found to be statistically significant. Conclusions : The result showed that Type D personality was one of the strong predictors of somatic complaints among depressive individuals. The finding that negative affectivity rather than social inhibition was more closely associated with somatization tendencies does not fully agree with the traditional explanation that inability to express negative emotion predispose the individuals to somatic symptoms. The finding that alexithymia was not shown to be a significant predictors also substantiated this discrepancy. However, it might be possible that the high correlation between NA and SI subscore(r=0.65) and between NA and TAS-20 score(r=0.44) hid the additional effects of social inhibition and alexithymia. Further research with a larger sample would be needed to investigate the effects of the latter two components over and above the effect of negative affectivity on the somatic complaints in depressive patients.

  • Transgene expression was analyzed in tomato plants. Four lines of neomycin phosphotransferase II gene (NPTII) and the trehalose biosynthetic fusion gene (TPSP) transformed $T_0$ plants showed kanamycin resistance on selection medium. However, the analysis of phenotype (kanamycin resistance) and mRNA expression in $T_1$ plants indicated that the expression of the NPTII and TPSP transgenes was down-regulated to an undetectable level in two independent lines 1 and 11. Southern analysis demonstrated that the lines 1 and 11 had multicopies of the transgenes, whereas the typical transgenic lines 2 and 10 had 1 or 2 copies. DNA methylation analysis using methylation sensitive enzyme detected accumulated CpG DNA methylation on TPSP coding region and CaMV35S promoter region in the line 11, but not the typical transgenic line 2. These results suggest that multicopy transgene in plants is attributed to down-regulation of the transgene expression via transcriptional gene silencing.

  • Objectives : The distressed personality (type-D) pattern, consisting of negative affectivity and social inhibition, has been shown by Denollet et al. For measuring the Type D characteristics, Denollet has devised the 14 item Type D scale (DS14). In the present study, this instrument was translated into Korean. The reliability and validity of the Korean DS14 was pilot tested. Methods : Preliminary version of the total 17-item DS14 scale was translated into Korean. 372 controls that did not have any coronary heart diseases (CHD) were randomly sampled in Seoul and Gyeonggi province. Preliminary Korean version was applied to controls and 14 items were finally selected to maximize reliability of the scale. We compared the distribution of type-D personality among the normal controls, hypertensive patients, and the CHD patients. Results : 7 of 10 items in social inhibition were selected and final 14-item version was made. The internal consistency of negative affectivity (0.817) and social inhibition (0.797) were high. In addition, the prevalence of type-D personality in the CHD patients group was significantly higher than normal controls. Conclusion : These findings suggest that Korean version of DS14 is a valid tool for measuring the type D characteristics. Type-D characteristics can be suggested to predict adverse prognosis in patients with CHD.

  • The purpose of this study is to find out the correlations between the stress that middle-aged women experience and their coping methods and to present intervening variables to promote active coping methods. The subjects of this study are 400 middle-aged women from 35 to 59 years old living in S area and the results are as follows. The relationship between middle-aged women's stress, self-defense mechanism, and stress-coping method shows as follows: the role stress is positively correlated with immature defense mechanism, self-restraint defense mechanism and conflict-avoiding defense mechanism. Among stress-coping methods, the problem-centered coping method was found to be negatively correlated with role stress and daily stress. the immature defense mechanism shows negative correlations with the problem-centered coping, but shows positive correlations with the emotion-centered coping and the wishful thinking. Among the self-defense mechanism types not effective in the social-support coping method.

  • 예로부터 인간은 단맛에 강한 욕구를 가지고 있었다. 따라서 설탕, 포도당, 과당 등 단맛이 강한 감미료를 선호하여 왔고, 현재까지도 식품 제조시 가장 널리 사용되고 있다. 그러나 최근에는 국민의 건강에 대한 관심이 고조 되고 설탕으로 대표되는 전통적인 일반 감미료의 충치, 비만, 당뇨병 유발 등의 부정적인 측면이 부각되고 있을 뿐만 아니라, 식품에 대한 건강 기능성이 강조되면서 기능성 감미료가 주목 받고 있다. 특히 고도의 경제성장 및 국민 소득의 향상에 따라 차별화된 기능성 감미료의 생산을 요구하는 실정이다. 이와 관련하여, 현재 식품 산업계에서는 올리고당류, 당알콜류, 고감미 감미료류 등에 많은 관심을 가지고 연구 개발에 집중하고 있다. 올리고당류의 대표적인 제품은 프락토올리고당, 갈락토올리고당, 이소말토올리고당 등이다. 현재 올리고단 시장은 성숙기로서 성장속도가 둔화되고 있으나, 최근 American Association of Cereal Chemists(AACC)등 세계적인 협회에서 수용성 식이섬유를 다당류, 올리고당, 리그닌 등을 포함하여 새롭게 정의하였고 이에 따라 해외에서는 프락토올리고당을 중심으로 수용성 식이섬유로 용도 사용이 가능하게 되었을 뿐만 아니라, 식이섬유로 표기도 가능하게 되어 수요가 증가할 것으로 예상된다. 국내에서는 아직 올리고당을 식이섬유로 사용하지는 못하고 있으나, 식품 공전 개정을 통해 식이섬유로 표기 가능하도록 수정될 전망이다. 당알콜류는 솔비톨 및 자일리톨이 주류를 이루고 있다. 솔비톨은 시장에 가장 먼저 소개된 당알콜류인데 저가여서 그동안 가장 큰 시장을 형성하고 있었으나 최근 3년 동안 자일리톨껌이 최대의 히트 상품이 되면서 자일리톨이 급성장하였다. 그 외에는 만니톨, 에리스리톨, 말티톨, 이소말트 등이 있다. 최근에는 말티톨을 중심으로 다양한 응용 연구 및 이소말트 및 에리스리톨 등을 생산 판매하고 있는 다국적 기업의 판촉 활동 등으로 당알콜류 시장의 새로운 변화가 예상된다. 고감미 감미료류는 스테비오사이드와 아스파탐이 주류를 이루고 있었지만, 최근 아세설팜 K 및 수크랄로스가 잇따라 식품으로써 사용 허가를 받으면서 시장이 재편되고 있다. 하지만, 해외에 비하여 국내의 고감미 감미료 시장은 매우 작고 성장률도 낮은 편인데 그 이유로는 국민 정서상 천연이 아닌 합성에 대한 부정적 인식과 맛에 대한 거부감 때문인 것으로 생각된다. 이와 관련하여 최근에는 다양한 감미질 및 Multi sweetener system 연구를 통해 설탕과 유사한 맛을 내는 혼합 기술 개발에 관한 연구가 진행되고 있다. 따라서 향후에는 해외의 선진국과 같이 고감미 감미료 시장도 점차적으로 확대될 것으로 예상된다. 기타 대체 감미료로는 타가토스, 트레할로스, 아라비노스 등이 있다. 이중에서 특히 해외에서 크게 기대를 모으고 있는 타가토스는 최근 국내 인증을 받아 시장 진출을 준비 중에 있다. 아라비노스는 양질의 감미를 갖는 천연 펜토오스인데 연구용 시약 이외에는 지금까지 거의 이용되지 않았다. 그러나 최근 아라비노스가 설탕의 소화흡수를 선택적으로 억제한다는 흥미 있는 결과가 임상 및 동물실험에서 확인되어 향후 제품으로써 개발을 기대할 수 있게 되었다. 이들 감미료는 기존 설탕이 가지는 문제점을 많은 부분 극복할 것으로 여겨지며, 이로 인해 수요는 점차 증가할 것으로 생각되며, 높은 경제적 부가 가치를 창출할 것으로 예상되어 진다. 생산 기술 적인 측면에서 건강 지향적 천연소재 감미료에 대한 선호가 날로 증가하는 추세에 따라 기존에 주로 사용되었던 화학합성법보다는 천연 이미지의 생물공학적인 방법에 의한 감미료 생산이 각광을 받을 것으로 예상된다. 생물공학적인 방법을 감미료 소재 개발에 응용하게 되면, 기존에 사용되었던 화학합성법 등이 가지는 환경적인 문제, 반응 부산물 생성에 따른 분리, 정제에서의 비용증가 등의 문제점을 해결할 수 있을 것으로 여겨지며, 고정화 방법의 도입 등을 통해 생산성 향상을 도모할 수 있다. 본 장에서는 감미료 소재 개발에 건강 지향적 국민 정서를 반영하고, 국내외 감미료 시장의 흐름을 파악하여 당류 산업의 발전적인 변화에 대처하고자 하였으며, 이를 통해 당류산업의 고부가가치 첨단산업으로서의 육성방안을 논의하고자 하였다.

  • The purpose of this study was to delve into parents who turned their children into creative achievers in the East and the West in an attempt to determine the cultural generality and specificity of the rearing of gifted children. The subjects in this study were Western parents, who brought up Marie Curie, Einstein, Edison and Newton, and Eastern parents, who raised Lee Hwang, Lee lee, Jeong Yak-yong and Heo Nanseolheon. To compare their parenting characteristics, common denominators and differences, a variety of data were investigated, including historical records about the parents, biographies, critical biographies, autobiographies and letters. As to the common features of the parenting style of the eight Asian and Western parents, they were talented themselves or capable of educating their children in their talent areas, and provided them with optimal learning environments or chances without pushing them. They accentuated independent spirits and emphasized renovative and open way of thinking. And at least one parent in each family showed absolute support for their child. Regarding differences in parenting style between the East and the West, the Western parents urged their children to develop their talents with more intention, rather the Asian parents prized the well-rounded personality and growth of their children. The former interacted with their children in an horizontal manner, but the latter had a vertical relationship with their children. The former expressed their feelings in an active way, but the latter had their emotion in control. Besides, the Western parents disclosed themselves to their children by showing them even their mistakes or improper behaviors, whereas the Asian parents strived in everyday life to give their children a good example or a good role model.

  • This study aimed to figure out the factors affecting the self-esteem of children. For this purpose, 296 fosterers (those who use the children education institutions) were targeted to analyze the factors affecting the self-esteem of children. The factors can be categorized as the personal internal factors (problematic behavior and self-control capability of the children) and the environmental factors (parenting efficacy and parenting stress of the fosterers). As a result, self-assessment, depression, emotionality, and behavioral restriction factors of the children and child-rearing efficacy, and the child-rearing stress of the fosterers were proven to be influential; these two factors have 50.5% of the explanation power. In conclusion, if self-assessment, emotionality, and behavioral control of the children and rearing efficacy of the fosterers were high, self-esteem of the children was increased. However, if depression of the children and rearing stress of the fosterers were high, self-esteem of the children was decreased. This result suggests a need of program development and a new teaching method to reduce problematic behavior of the children and rearing stress of the fosterers, as well as to enhance rearing efficacy of the fosterers and self-control capability of the children for the purpose to increase self-esteem of the children.

  • This study examined the difference between parents' and teachers' recognition about problem behaviors of children. The findings showed that there was a distinct difference between parents' and teachers' recognition about all problem behaviors of children. Especially, teachers had more recognition about problem behaviors of children than parents. And the reactive interaction and the actual prevention in educational institutions were preferred in the difference between parents' and teachers' recognition about a teaching strategy for children, such that teachers had significantly higher recognition about a teaching strategy for children than parents did, while there was no significant difference in the strategy for social emotion. This means that teachers should originally control and manage various problem behaviors based on the common teaching strategy, which is socio-emotionally recognized, rather than the biased teaching strategy. But the teaching strategy of reactive interaction is preferred in accordance with the type of problem behaviors between teachers and children and the children who show problem behaviors. Especially, teaching strategies of reactive interaction and actual prevention focused on the inhibition and prevention of children's problem behaviors are preferred in light of children's characteristics of many unexpected problem behaviors.

  • This study attempted to examine the role of gender roles in psychological distress of Korean adult men. Specifically, it was attempted to verify whether compliance with multidimensional male gender roles predicts psychological distress through gender role conflict. To this end, this study was conducted on 358 male participants aged 19 to 39 using the Korean Conformity to Masculine Norm Inventory, Korean Male Gender Role Conflict Scale, and General Health Questionnaire. As a result of the study, it was found that the influence on psychological distress through male gender role conflict was different depending on the sub-factors of the male gender norm. The sub-factors of masculine norms, 'power and control', 'job - independence', and 'emotion suppression', were statically predicted psychological distress through the medium of 'fear for femininity', which is a sub-factor of gender role conflict. Meanwhile, among the male norms, 'male leadership' and 'family support' had negative direct effects on psychological distress, and the indirect effects through gender role conflict were not significant. The results of this study suggest that the sub-factors of male norms have different functions for psychological distress, and in particular, the dysfunctional role of male norms can be caused by negative emotions about femininity during gender role conflict.

  • Recently, enviromentally friendly natural substances derived from plants have been attracting attention as cosmetic materials, and research on various physiological activities of natural substances is being actively conducted. This study investigated the antioxidant, anti-inflammatory, moisturizing, and antibacterial effects of three types of extracts of mixtures containing different mixing ratios, Polygala tenuifolia, Angelica dahurica, and Elsholtzia splendens, known to have various physiological activities. The mixing ratio is 7 conditions (M1, 1:1:1; M2, 0.5:1.5:1; M3, 1.5:0.5:1; M4, 0.1:0.95:0.95; M5, 0.5:0.5:2; M6, 0.95 :1.95:0.1; M7, 1.45:0.1:1.45), and the optimal mixing ratio was confirmed for use as a cosmetic material. DPPH and ABTS radical scavenging activities showed scavenging abilities of 75.37% and 99.19%, respectively, at 1,000 ㎍/mL of M6. At a concentration of 200 ㎍/mL of M6, it showed 50% of nitric oxide production inhibition compared to the lipopolysaccharide-treated that induced an inflammatory response. It was confirmed that M3 and M6 produced hyaluronic acid 1.47 and 1.49 times higher than the control at a concentration of 50 ㎍/mL, respectively. Through the disc diffiusion test, the clear zone was 9.75 mm at 8 ㎍/mL of M6, confirming the inhibition of growth of staplylococcus aureus strain. Based on the above results, it is believed that the mixed extract of Polygala tenuifolia, Angelica dahurica, and Elsholtzia splendens can be used as a functional natural material for cosmetics.
