The purpose of this study was to investigate housewives' perception, interest and consumption of organic food, and to identify the variables influencing on them. The sample was selected from 411 housewives living in Seoul from 1st of September to 20th of September in 1993. Used statistical methods were frequency, percentage, mean, Cronbach's ${\alpha}$, factor analys, ANOVA, Duncan's multiple range test, t-test, correlation, regression analysis and Path analysis. The major results are as follows: 1) Housewives' perception degree of organic food in its variety, easy availability and contribution to health was relatively high level, but price level, reliability and packing condition was somewhat low level. Out of housewives' many images of organic food, taste health care, quality and necessity factors can be implicated. 2) Housewives' interest degree of organic food is somewhat high level 3) Housewives' consumption degree of organic food was relatively low level and was affected by their perception of oraganic food. 4) Frequency to use seasonings was the major independent variable which influenced to housewives' perception degree of organic food, while recognition on enviornmental contamination was the major independent variable which influenced to their interest degree of organic food, and their total perception on organic food was the major independent variable which influenced to their consumption degree of oragnic food. Therefore, it is considered that their total perception to it can decide the demand of organic food 5) Housewives' perception and interest degree of it was the major intervening variable which influenced to their consumption degree of oragnic food.

Objective: This study aimed, first, to develop core strength training equipment with elderly-friendly, easy-to-use features and, second, to investigate the effect of core strength training using the equipment on the performance and stability of the elderly in activities of daily living. Method: In this study, we developed training equipment with a stability ball that can be used for performing core strength exercises in the elderly. Twenty-three elderly subjects (age: $77.87{\pm}6.95years$, height: $149.78{\pm}6.95cm$, and weight: $60.57{\pm}7.21kg$) participated in this study. The subjects performed the core strength training exercise with 16 repetitions for 8 weeks (2 repetitions per week). Performance in activities of daily living was assessed by using the Short Physical Performance Battery (SPPB), a test of going up and down 4 stairs, and one-leg static balance test. Stability was quantified as changes in the center of pressure (COP) and C90 area. Results: With the core strength equipment, trunk core strength exercise could be performed by pulling or pushing a rope with 2 hands on the stability ball. During the task, the tension in the rope was manipulated by a motor connected to the rope and the COP of the subject was measured by 4 load cells mounted in the equipment. Our results showed that the SPPB score was significantly higher (p < .05), the time to complete the "going up and down 4 stairs" test was significantly shorter (p < .05), and one-leg static balance statistically improved under an eyes-open condition (p < .05) after as compared with before the core strength training. The changes in the COP in the anteroposterior and mediolateral directions, and C90 area were significantly lower in the posttest (p <. 05) than in the pretest. Conclusion: The core strength training exercise using the equipment developed in the present study improved the performance and stability of the elderly in activities of daily living.

이 글은 서울 진오기굿의 의례형식을 중심으로 의례적 특징을 살펴보고자 하였다. 이 글은 서울 진오기굿의 의례상 특징으로 저승길의 가시적 구현, 망자와의 직접적인 의사소통, 죽은 자와 산 자를 아우르는 포괄적인 축원 등 세가지를 지적하였다. 먼저 서울 진오기굿은 굿의 의례과정을 통해 죽은 자의 저승길을 가시적으로 구현한다. 이는 유교, 불교의 죽음의례 뿐만 아니라 타 지역 무속 죽음의례와 비교했을 때도 상대적으로 두드러지는 서울 진오기 굿의 특징 가운데 하나이다. 두 번째로 서울 진오기굿에서는 무당의 신내림을 매개로 죽은 자와의 의사소통이 직접적인 대화형식으로 이뤄진다. 죽은 망자와의 직접적인 의사소통은 죽음을 현실로 받아들이고, 개개 죽음의 개별성과 특수성을 확인하는 의미를 갖는다. 세 번째로 서울 진오기굿에서 이뤄지는 축원은 죽은 자의 저승천도에 머물지 않고 살아있는 가족들의 평안까지 포괄한다. 이는 죽음이 죽은 자와 산 자에 다 관련되며, 죽음과 삶은 구분되나 분리되지 않는다는 무속의 죽음이해를 보여준다. 이 글에서 밝힌 서울 진오기굿의 의례적 특징은 유교, 불교 죽음의례와의 상대적 비교를 염두에 둔 것으로, 그것은 유교, 불교 죽음의례와의 상호관계에서 어떻게 무속 죽음의례가 한국사회에서 하나의 죽음의례로서 존재가치와 기능을 인정받아왔는가를 이해하는 단서를 제공한다.

The free-living nematode, Caenorhabditis elegans (C. elegans) has been adopted as a multicellular biosensor of biological toxicity for alkylphenol, organotin compounds and heavy metals. To adopt as a biosensor, suitability to assess must be fulfilledthrough several criteria; the organism must be sensitive to the testing toxicants, easy to manage in the laboratory and available throughout the year. C. elegans widely used as a simple multicellular organism in developmental biology studies and satisfies all these criteria, and its culture conditions, developmental staging, anatomy and genetic properties are well defined. In addition, researchers can take advantage of the worm's short life cycle, low cost and little individual variation. Moreover, genomic sequencing of C. elegans has recently been completed. With these aspectsof the organism, C. elegans become a more potent model organism for basic and applied bioassays.

Some microorganisms, including actinomycetes, cyanobacteria, and other bacteria, algae, fungi, and yeast, can accumulate and retain relatively high quantities of heavy metals and radionuclides from their external environments (1-4). Both living and dead cells can be used for biosorptive metal/radionuclide removal from solution. Thus microorganisms and products excreted by or derived from microbial cells (2) may provide an alternative or adjunct to conventional techniuqes of metal removal and recovery. Recent approaches have separated the microbial growth and metal removal process to manipulate production of metal-adsorptive capacity of bacteria and metal removal process. If pre-grown cells are immobilized and used for metal removal, mathematical modeling can be applied to predict immobilized cell reactor behavior under specific process conditions. Waste and microbial adsorbent could be separated from the treated flow in one step. Once treated, the metal waste is concentrated in a small volume of sorbed form for easy metal disposal or recovery.

Living in the age of information people face problems related to information overload. Information is easy to produce, store and distribute through various communication channels, one of which is emails. With the appearance of the mobile devices, such as smart phones and tabs, people can have access to email inbox at any moment of time from everywhere. In this paper we present information extraction system with a specific goal of extracting meeting location from the announcement of seminar or conference. We apply a machine learning method (conditional random fields, CRF), train the system using annotated corpus of seminar and conference announcements and validate results by applying various extracted correction rules and patterns. Furthermore, we normalize extracted location, and reference using geo-coding databases, OpenStreetMap and Wikipedia resources to determine real geographical coordinates.
