  • A bioassay-guided fractionation of the whole extract of Viscum album var. coloratum Ohwi (Loranthaceae) led to the isolation of two triterpenoidal components; oleanolic acid (1) and ${\beta}-amyrin$ acetate (2), and a flavonoid, homoflavoyadorinin B (3) as well as large quantity of free fatty acid mixtures as active ingredients of the extract responsible for the antitumoral property. The EtOAc soluble fraction and BuOH soluble fraction of the extract demonstrated a significant inhibition on the proliferation of cultured human tumor cells such as A549 (non small cell lung), SK-OV-3 (ovary), SK-MEL-2 (melanoma), XF498 (central nerve system), and HCT-15 (colon) in vitro, whereas the remaining water soluble fraction exhibited a poor inhibition. The intensive phytochemical investigation of the EtOAc soluble fraction and BuOH soluble fraction of the extract indicated that the oleanolic acid (1) and large amounts of free fatty acid mixtures might be attributed to the in vitro antitumoral property of the whole extract of Viscum album var. coloratum.

  • Purpose: This study investigated the prevalence of middle school students with ADHD and the level of middle school teacher's knowledge, coping strategies, and educational intervention for ADHD. Methods: There were 185 teachers and 6,381 middle school students at the 6 middle schools in Pusan. The data was collected from December 20, 2003 to January 10, 2004. Results: 195 middle school students had ADHD (3.1%). The male students with ADHD made up 4.4% of the total students and the female students with ADHD totaled 1.3%. The mean score of middle school teacher's knowledge about ADHD was 21.86 of the score total 32. The teachers used a negative coping style less than an active and passive coping style. Of the educational interventions, the environmental intervention in the classroom was used more than the educational intervention activity. 61.1% of the teachers responded that they did not know very much about ADHD. 93.5% of the teachers had no educational experience with ADHD. 94.1% felt that they needed an education program about ADHD and over half of them intended to participate in an ADHD education program. Conclusion: Based on the results of this study, we concluded that the middle school teachers felt that they had insufficient knowledge about ADHD. They wanted the opportunity to increase their knowledge of ADHD. Therefore, it is necessary for educational programs about ADHD for teachers to be developed and made available to them.

  • For the asset management of a water pipe network, it would be necessary to understand the extent of the maintenance cost required for the water pipe network for the future. This study would develop a method to draw the optimum cost required for the maintenance of the water pipe network in waterworks facilities to maintain the aim revenue water ratio and to achieve the target revenue water ratio, considering the water service providers' waterworks condition and revenue water ratio comprehensively. This study conducted a survey with 96 water service providers as of the early 2015 and developed models to estimate the optimum maintenance cost of the water pipe network, considering the characteristics of the water service providers. Since the correlation coefficient of all the developed models was higher than 0.95, it turned out that it had significant reliability, which was statistically significant. As a result of applying the developed models to the actual water service providers, it was drawn that increasing revenue water ratio to more than a certain level can reduce the maintenance cost of the water pipe network by a great deal. In other words, it is judged that it would be the most efficient to secure the reliability of waterworks management by increasing the short-term revenue water ratio to more than a certain level and gradually increase the revenue water ratio from the long-term perspective. It is expected that the proposed methodology proposed in this study and the results of the study will be used as a basic research for planning the maintenance of water pipe network or establishing a plan for waterworks facilities asset management.

  • 고객불만에 대한 대응은 고객과의 관계를 형성하고자 하는 기업목표 달성에 매우 중요한 요소가 된다. 인터넷 상거래 상장에서, 다양한 대안 그리고 낮은 전환 비용 등의 특성 때문에 고객불만에 대한 효과적인 대처는 오프라인 시장에 비해서 그 중요성이 더욱 강조되고 있다. 본 연구에서는 인터넷 쇼핑몰의 불평처리를 경험한 고객들을 대상으로 1) 불만 (상품관련, 쇼핑몰관련)이 쇼핑몰과 고객간의 관계형성에 미치는 부정적인 영향에 대해 확인하고, 2) 불평처리의 세 가지 공정성(분배적, 절차적, 상호적) 지각이 불만과 신뢰 및 결속몰입간의 관계에 어떠한 조절효과를 갖는지 검증하였다. 상품관련 불만과 결속과의 관계를 제외하고, 대체적으로 불만은 신뢰와 결속에 부정적인 영향을 미치는 것으로 나타났다. 조절효과에서는 분배적 공정성이 확보된 경우 불만과 신뢰 및 결속의 부정적 관계가 대체적으로 완화되었으며, 절차적 공정성의 확보는 상품관련 불만이 신뢰와 결속에 미치는 부정적 관계를 상호적 공정성의 확보는 불만과 신뢰의 부정적 관계를 완화하는 것으로 나타났다.

  • The aim of this study was to assist the development of parenting-aid policies by analyzing information from life perspectives, family system theory, and integrated family policy perspectives. For this purpose, we conducted a literature using a variety of sources including internet sites, laws, published material related to current parenting-aid policies. Based on analyses we formulated four agendas: empowering parent competency, supporting diverse family parenting, guaranteeing parent's rights, and supporting parenting of dual-income families parenting. The results were as follow: Firstly, for empowering parent competency, we proposed the development of family relationship empowerment programs including family life cycle and children-raising support services. Secondly, for diverse family parenting, we proposed access to integrated parenting-aid programs dependent on family types. Thirdly, for guaranteeing parent’s rights, we proposed the supporting of child raising costs and tax returns to families with children, and provide child allowances. Finally, for dual-income family parenting, we proposed that schools and communities must recognize that dual-income families are a universal family type, establish family friendly business culture, and to develop a more democratic domestic family-relationship. This policy proposed a new paradigm where parents must be recognized as partners and stakeholder in development of family related policies. Ultimately, such policies will contribute to increased birth rate and development of a more respectful society.

  • 우리는 O/Fe(100)의 원자적 구조와 MgO/Fe(100) 표면의 계면의 구조를 LEED I/V curve를 이용하여 분석하였다. 산소를 Fe(100) 표면에 흡착시켰을 때 Fe 표면의 첫 번째 층간 간격은 약 16 % 정도 팽창하는 것을 확인하였다. 1ML MgO를 Fe(100) 표면에 성장하였을 때, MgO의 O가 Fe의 on-top 위치에 자라나는 것을 확인하였고, MgO/Fe 계면의 층간 간격이 확장되는 것을 확인하였다. AIA(average intensity mixing approximation) 계산을 사용하여 단층 MgO 성장한 Fe(100) 계의 계면구조는 MgO/FeO/Fe(100)와 MgO/Fe(100)의 계면구조를 갖는 것을 확인하였다. 이것은 확장된 FeO 층의 존재를 보이고 MgO/FeO/Fe(100)와 MgO/Fe(100) 두가지 계면 구조의 공존을 보인 EELS 실험 결과를 뒷받침 한다.

  • The global volume of luxury fashion industries has continuously grown with the influx of young consumers in 20s and 30s, yet little research explores luxury consumption patterns of the young consumers. Given the crucial importance of socio-psychological shopping values in luxury, the current study explores the effects of self-congruity and functional congruity on purchase intentions of luxury fashion brands, and the moderation of self-construal in the mechanisms. An online study was conducted through Google Forms with a total of 227 Korean respondents of actual luxury consumption experiences. The data was analyzed using SPSS 18.0 program. The results of the study reveal the following: (i) Among the three factors of self-congruity, ideal and social self-congruity factors have significant positive effects on purchase intentions; (ii) actual self-congruity has no statistical effect on purchase intnetions of luxury fashion brands; (iii) functional congruity has a significant positive effect on purchase intentions of luxury fashion brands; (iv) no moderation effect of self-construal was found in the relationships between the three factors of self-congruity and purchase intentions; (v) the moderation effect of independent self-construal is significant but negative in the relationship between functional congruity and purchase intentions; (vi) the effect of intdependent self-construal is not found to be significant in the relationship between functional congruity and purchase intentions. Managerial and theoretical implications are discussed.
