Objectives: Food literacy (FL) can be an important concept that embodies the nutritional capabilities of individuals. The purpose of this study was to introduce the definition and core elements of FL from previous literature, to summarize measurement tools and intervention programs with FL, and to suggest the direction of future research and programs to integrate the concept of FL. Methods: The literature review was conducted through PubMed and Google Scholar databases by combining the search term 'food literacy' with 'definition', 'measurement', 'questionnaire', 'intervention', and 'program'. Among the 94 papers primarily reviewed 31 manuscripts that suited the purpose of the study were used for analyses. Results: There is no consensus on the definition of FL that encompasses the multidimensional aspects of the concept. The definitions of FL were slightly different depending on the authors, and the interpretation of the core elements also varied. Based on the review, we propose a framework of FL that is in line with the current discussion among international researchers. This focuses on the core elements adapted from health literacy, namely functional, interactive, and critical FL. Specifically, we suggest some detailed elements for interactive and critical FL, which were often the subject of divergent views among researchers in previous literature. We found that most of the tools in the reviewed literature provided information on validity and reliability and were developed for a specific target population. Also, most of the tools were focused on functional FL. Similarly, most of the interventions targeted functional FL. Conclusions: This study reviewed the definition and core elements of FL, available measurement tools, and intervention programs using validated tools. We propose the development of tools with sound reliability and validity that encompass the three core elements of FL for different age groups. This will help to understand whether improving food literacy can translate into better nutritional intake and health status among individuals and communities.

포름알데하이드는 호흡기 및 피부 질환을 일으키는 등 인체에 유해한 실내 환경 오염물질로 알려져 있다. 본 연구에서는 활성탄소섬유 표면에 질소 작용기를 도입하기 위하여 질소 플라즈마 처리를 하였고, 질소 작용기 함유 활성탄소섬유에 대한 포름알데하이드 흡착 특성을 고찰하였다. 주입되는 질소 가스의 유량이 증가함에 따라 활성탄소섬유 표면에 도입되는 질소 작용기의 함량이 약 7% 정도 증가하였으며, 존재하는 질소 작용기의 종류별 비율도 유사하였다. 또한 플라즈마 처리에 의한 식각 효과로 인하여 활성탄소섬유 표면에 초미세기공이 증가하였다. 이에 따라 표면 개질된 활성탄소섬유의 포름알데하이드 흡착 효율도 증가하였다. 그러나, 질소 유량이 120 sccm 이상인 조건에서는 활성탄소섬유 표면이 과도하게 식각되어, 비표면적이 감소하고 포름알데하이드 흡착 능력이 오히려 저하되었다. 따라서, 질소 플라즈마 처리된 활성탄소섬유의 포름알데하이드 흡착은 도입된 질소 작용기의 함량이 주요 요인이지만, 이와 함께 적합한 기공 구조를 가질 때 포름알데하이드의 흡착 효율이 향상됨을 알 수 있었다.

Objectives : Cognitive therapy is the most extensively researched psychological treatment for nonpsychotic unipolar outpatient depressive disorders. This review focused on the utility of this approach in severe or chronic depressive disorders, in relapse prevention and also on the potential benefits of combining cognitive therapy with medication. Methods : The author reviewed original studies and quantitative analyses on the effects of cognitive therapy, predictors of response, and neuroimaging studies of cognitive therapy in major depressive disorder. The sources used for the literature search were data bases : PubMed, EMBASE, CDSR on the internet, references in papers or books. Results : This review suggests that cognitive therapy is as effective as antidepressant medication in severe depressive disorders. And cognitive therapy can be an effective alternative to antidepressant medication. Patients benefited significantly more from combined cognitive therapy and antidepressant treatment than from either treatment alone. Most importantly, the addition of cognitive therapy to usual treatment appears to protect against future relapse in individuals known to be at high risk of repeated episodes of depression. In addition, subjects who received cognitive therapy showed significantly greater improvements in chronic depression than receiving antidepressant medication. Pooled data suggests that there is a significant relationship between the therapist's level of training or experience, the type of therapy used and patient outcome. Recent functional imaging studies examining brain changes following cognitive therapy report a variety of regional effects, but there is no consistent pattern across the few published studies. Conclusion : Cognitive therapy has proved beneficial in treating depressive patients. Despite empirical data supporting its efficacy, there are still problems in gaining access to cognitive therapy in clinical practice.

Recently, many studies have focused on the aging and oxidative stress. Several papers reported that Vigna angularis has various biological properties including antiaging, antioxidative and anti-inflammatory activities. Methanol extract from the red bean sprouts was successively partitioned as n-hexane, methylene chloride, ethyl acetate, n-butanol and H₂O soluble fractions. We had studied lifespan extending and stress resistant effects of the fractions using Caenorhabditis elegans. Superoxide dismutase (SOD), catalase activities, and intracellular reactive oxygen species (ROS) levels were also investigated. Moreover, we had studied to find any significant change in aging-related factors such as reproduction, food intake, growth and movement of C. elegans. Our results represent that ethyl acetate fraction showed the most potent lifespan extending and stress resistant effects, and this fraction was able to elevate SOD and catalase activities of worms, and reduce intracellular ROS accumulation.

디지털 정보 혁명과 정보 기술의 발달은 고객의 다양한 욕구를 유발하였고 점차 기업들의 격화된 경쟁하의 생존전략으로서 물류 서비스 향상을 위한 물류 흐름이 기업 경쟁력의 중요한 요소로 부상하고 있다. 또한 공급자와 소비자 간의 정보공유는 기능 중심에서 프로세스 중심이 되면서, 유연성과 고객 서비스를 극대화하기 위한 새로운 물류 개념을 요구하게 되었다. 현재까지 대부분의 수 배송 연구는 방문순서나 방문시간의 제약조건에 따라 수요처에 대한 도착시간 및 선행순서에 대한 제약이 없는 경우의 차량경로문제(VRP)나 시간 및 선행순서에 대한 제약이 있는 경우의 차량일정계획문제(VSP)로 연구되어져 왔다. 그러나 현실적으로는 배송센터에서 제약 조건에 따라 고객까지 차량일정계획 수립을 위한 시간 보다는 배차계획을 수립하는데 더 많은 시간이 소요되는 것으로 알려져 있다. 본 논문은 물류 서비스의 향상을 위한 배차계획 업무의 현실적인 제약 조건들을 고려하여 배차계획 시스템을 설계하고, 이 설계 모듈에 따라 배차계획의 수정작업 조정시간를 효율적이고 획기적으로 줄일 수 있는 배차계획 시스템의 발견적 알고리듬을 설계하고 구현토록 한다.

The purpose of this study is firstly to survey the social and cultural background of 20th century and women´s status, and to identify what the ideal body is like and what the elements of outer garment and underwear are and the techniques to incarnate the ideal beauty. Various papers are referenced for theoretical study and the elements and techniques of underwear are analyzed based on photographical materials. This paper concludes as follows. In 1960´s, ideal beauty was small bust, long legs, which showed extremely slim Mini-skirt look. Thinly or no padded brassiere were worn for small bust, and pants-style short panty girdles were popular as they used to wear pants frequently. Lycra replaced all the closures, bones, seams and gave freedom with light weight. In 1970´s, a natural human body without sex specific was in vogue. Therefore, the non-structural knits without a pad or lining or the shirts dress were widespread for a Natural look and the naturally molded brassiere or girdles were worn as the underwears. In 1980´s, the women with powerful muscle appear which emphasized liveliness and healthfulness. The body conscious represented by wide shoulder, plump breast, accented waist, small hips, and long legs has been embodied. Outer garments emphasized women power and healthy beauty with Power suit and Form-fitting style, and underwears made the breast plump with padded brassiere and emphasized waist and hips with waspie. In 1990´s, ideal beauty was slim body with big bust and the outer garments emphasized body line of women with Hourglass silhouette. Push-up bra which emphasizes the valley of breast and supports the breast upward and the control tights for slim waist, flat abdomen, small hips, and long and slim legs have been useful as underwears. Multi-functional micro-fiber has been ideal for sculpting women body.

The actin cytoskeleton plays an important role in macrophage-mediated inflammatory responses by modulating the activation of Src and subsequently inducing nuclear factor (NF)-${\kappa}B$ translocation. In spite of its critical functions, few papers have examined how the actin cytoskeleton can be regulated by the activation of toll-like receptor (TLR). Therefore, in this study, we further characterized the biological value of the actin cytoskeleton in the functional activation of macrophages using an actin cytoskeleton disruptor, cytochalasin B (Cyto B), and explored the actin cytoskeleton's involvement in morphological changes, cellular attachment, and signaling events. Cyto B strongly suppressed the TLR4-mediated mRNA expression of inflammatory genes such as cyclooxygenase (COX)-2, tumor necrosis factor (TNF)-${\alpha}$, and inducible nitric oxide (iNOS), without altering cell viability. This compound also strongly suppressed the morphological changes induced by lipopolysaccharide (LPS), a TLR4 ligand. Cyto B also remarkably suppressed NO production under non-adherent conditions but not in an adherent environment. Cyto B did not block the co-localization between surface glycoprotein myeloid differentiation protein-2 (MD2), a LPS signaling glycoprotein, and the actin cytoskeleton under LPS conditions. Interestingly, Cyto B and PP2, a Src inhibitor, enhanced the phagocytic uptake of fluorescein isothiocyanate (FITC)-dextran. Finally, it was found that Cyto B blocked the phosphorylation of vasodilator-stimulated phosphoprotein (VASP) at 1 min and the phosphorylation of heat shock protein 27 (HSP27) at 5 min. Therefore, our data suggest that the actin cytoskeleton may be one of the key components involved in the control of TLR4-mediated inflammatory responses in macrophages.

Objective: The present study systematically analyzed the characteristics of ergonomic layout optimization methods by a comprehensive literature survey. Background: Although layout design methods for ergonomic placement of controls and displays on a console have been developed, understanding of their characteristics is lacking. Method: The present study analyzed layout optimization papers published past 20 years from the following four aspects: optimization model, optimization algorithm, design principle, and constraint/assumption. Results: The existing layout optimization methods based on various optimization techniques consider only a partial set of four layout principles(importance, frequency of use, sequence of use, and functional grouping) and two ergonomic criteria(visibility and reach). In addition, the existing methods oversimplify components in various sizes, shapes, and angles by assuming the equality of the components in size and shape. Conclusion: A more effective layout optimization method is needed which considers the layout principles and ergonomic criteria in a comprehensive manner and reflect the diversity of components in size and shape. Application: The identified characteristics on the existing layout optimization methods can be applicable to development of a better ergonomic console layout design method.

PURPOSE. To present a literature review on implant overdentures after a brief survey of bone loss after extraction of all teeth. MATERIALS AND METHODS. Papers on alveolar bone loss and implant overdentures have been studied for a narrative review. RESULTS. Bone loss of the alveolar process after tooth extraction occurs with great individual variation, impossible to predict at the time of extraction. The simplest way to prevent bone loss is to avoid extraction of all teeth. To keep a few teeth and use them or their roots for a tooth or root-supported overdenture substantially reduces bone loss. Jaws with implant-supported prostheses show less bone loss than jaws with conventional dentures. Mandibular 2-implant overdentures provide patients with better outcomes than do conventional dentures, regarding satisfaction, chewing ability and oral-health-related quality of life. There is no strong evidence for the superiority of one overdenture retention-system over the others regarding patient satisfaction, survival, peri-implant bone loss and relevant clinical factors. Mandibular single midline implant overdentures have shown promising results but long-term results are not yet available. For a maxillary overdenture 4 to 6 implants splinted with a bar provide high survival both for implants and overdenture. CONCLUSION. In edentulous mandibles, 2-implant overdentures provide excellent long-term success and survival, including patient satisfaction and improved oral functions. To further reduce the costs a single midline implant overdenture can be a promising option. In the maxilla, overdentures supported on 4 to 6 implants splinted with a bar have demonstrated good functional results.
