In this study, I grasped the actual conditions of folk exhibition hall in Chungbuk area. From this data I researched basically as the fundamental role of regional museum, eco-museum core center facilities, the connection with islanded and various inheritances, and central facilities whole area to the museum. And I could get following conclusion. First, on the studied result of folk exhibition hall in chungbuk area, it is not enough the activity of unearthing, collection, study etc. that is basic activity of the museum because the museum just permanently displayed historical contents of the area and simple life folk data. Second, add to existent museum concept and have to widen viewpoint to the museum which whole area is no roof, and utilize folk exhibition hall as the central facilities. Specially, there are a lot of difficulties to communicate information to visitors because of the absence of cultural heritance exponent. So a plan that local resident participate actively in museum activity may have to be considered. Third, the concept of inheritance limited in historical culture of area has to be widening by nature and industry etc. And we should keep up study that is the linked plan to scattered conservation remains, inheritance and tourist place in area.

Chemical speciation of five heavy metals (Cr, Cu, Ni, Pb, Zn) has been analyzed from 37 surface and 2 core sediments of Kyeonggi Bay, using the modified sequential extraction method based on Tessier et at. (1979). The results show that heavy metals in the Kyeonggi Bay surface sediments are associated dominantly with the crystal lattice fraction. But in the polluted sediments of the Incheon North Harbor, the importance of the labile fractions increased while that of the lattice fraction decreased. In particular, the adsorbed and the easily reducible fractions showed a noticeable increase. In the core samples emerged a speciation pattern which differed significantly from that of the surface sediments. A sharp increase in the percentage of the reducible and organic/sulfide fractions and a decrease in the lattice fraction were observed. Throughout the vertical column, however, the metal contents in the lattice fraction showed stability while those of the labile fractions showed an upward increase. The strong association of heavy metals with the organic/sulfide fraction could be attributed in part to the sulfate reduction prevailing in the polluted harbor sediments.

This study was conducted to develop a Web-GIS based monitoring module of smart city that can effectively respond, manage and improve situation in all stages of illegal dumping management on a city scale. First, five technologies were set for the core technical elements of the module configuration. Five core technical elements are as follows; video screening technology based on motion vector analysis, human behavior detection based on intelligent video analytics technology, mobile app for receiving civil complaints about illegal dumping, illegal dumping risk model and street cleanliness map, Web-GIS based situation monitoring technology. The development contents and results for each set of core technical elements were evaluated. Finally, a Web-GIS based 'illegal dumping monitoring module' was proposed. It is possible to collect and analyze city data at the local government level through operating the proposed module. Based on this, it is able to effectively detect illegal dumpers at relatively low cost and identify the tendency of illegal dumping by systematically managing habitual occurrence areas. In the future, it is expected to be developed in the form of an add-on module of the smart city integration platform operated by local governments to ensure interoperability and scalability.

The LBS (Location-Based Services) are valuable information services combined the location of moving object with various contents such as map, POI (point of Interest), route and so on. The must general service of LBS is route determination service and its applicable parts are FMS (Fleet Management System), travel advisory system and mobile navigation system. The core function of route determination service is determination of optimal route from source to destination in various environments. The MODB (Moving Object Database) system, core part of LBS composition systems, is able to manage current or past location information of moving object and massive trajectory information stored in MODB is value-added data in CRM, ERP and data mining part. Also this past trajectory information can be helpful to determine optimal route. In this paper, we suggest methods to determine optimal route by querying past trajectory information in MODB system and verify the effectiveness of suggested method.

Digital content industry is growing rapidly because of the property of high-speed networking and greater demand for digital fulltext-image. However, we know the fact that it is many difficulty in production and supply for good quality of content. Hereupon, we suggest digital fulltext-image service framework to protect copyright. More concretely, we propose integrated model and reference model to securely serve digital fulltext-image by recompositing core objects and reconstructing the value-chain structure of digital content industry to framework including the process(from its production (creators or copyrighters) to consumption (users or consumers)). Also, we construct the digital fulltext- image service system based on reference model and reconstruct its interface that occurs between core subjects.

Objective: This study observed the effects of cooking method and final core temperature on cooking loss, lipid oxidation, aroma volatiles, nucleotide-related compounds and aroma volatiles of Hanwoo brisket (deep pectoralis). Methods: Deep pectoralis muscles (8.65% of crude fat) were obtained from three Hanwoo steer carcasses with $1^+$ quality grade. Samples were either oven-roasted at $180^{\circ}C$ (dry heat) or cooked in boiling water (moist heat) to final core temperature of $70^{\circ}C$ (medium) or $77^{\circ}C$ (well-done). Results: Boiling method reduced more fat but retained more moisture than did the oven roasting method (p<0.001), thus no significant differences were found on cooking loss. However, samples lost more weight as final core temperature increased (p<0.01). Further, total saturated fatty acid increased (p = 0.02) while total monounsaturated fatty acid decreased (p = 0.03) as final core temperature increased. Regardless the method used for cooking, malondialdehyde (p<0.01) and free iron contents (p<0.001) were observed higher in samples cooked to $77^{\circ}C$. Oven roasting retained more inosinic acid, inosine and hypoxanthine in samples than did the boiling method (p<0.001), of which the concentration decreased as final core temperature increased except for hypoxanthine. Samples cooked to $77^{\circ}C$ using oven roasting method released more intense aroma than did the others and the aroma pattern was discriminated based on the intensity. Most of aldehydes and pyrazines were more abundant in oven-roasted samples than in boiled samples. Among identified volatiles, hexanal had the highest area unit in both boiled and oven-roasted samples, of which the abundance increased as the final core temperature increased. Conclusion: The boiling method extracted inosinic acid and rendered fat from beef brisket, whereas oven roasting intensified aroma derived from aldehydes and pyrazines and prevented the extreme loss of inosinic acid.

함암모늄 2:1 점토광물 내 암모늄 거동과 질소동위원소 특성을 살펴보기 위해 일본 남서부 해저 와카미코 화구(Wakamiko crater) 내 열수가 분출하는 두 지점에서 퇴적물 코어를 채취하여 스멕타이트로 대표되는 점토입자를 추출하였다. 점토입자 내 무기탄소 제거 후 순차적인 유기물 분해과정에서 감소하는 탄소-질소 비에 근거하여 무기질소 함량을 추정한 결과, 전질소에 대한 무기질소 비율은 SES 지점(Core#1093MG: av. 11.5%)에 비해 SWS 지점 (Core#1094MR: av. 18.2%)에서 높은 경향을 보였다. 후자에서 높은 광물 결정도를 보인 점은 상대적으로 진전된 광물화와 함께 교환성 암모늄이 비교환성 암모늄으로 전환된 결과로 해석된다. 단계적인 점토입자 내 교환성 암모늄의 제거과정에서 나타난 질소동위원소 조성 변화(SES 지점: Core#1093MG: -4.4 ~ +0.2 ‰, av. -2.4 ‰; SWS 지점: Core#1094MR: -0.7 ~ +3.0 ‰, av. +1.5 ‰)로부터 심부 마그마에서 비롯된 열류 및 열수에 의한 국부적인 온도변화는 함암모늄 2:1 점토광물의 형성에 관여한 유체 내 용존 암모늄과 암모니아 사이에서 질소동위원소 분별을 야기했을 것이다.

본 연구의 목적은 교육과정 분석을 위한 연계성 및 중복성의 준거유형을 개발하여 현행 2015개정교육과정의 초등 및 중등의 '가정생활' 분야의 내용 연계성 및 중복성을 분석함으로써 차기 교육과정 구성을 위한 기초 자료를 제공하는 데 있다. 교육과정 구조화의 원리가 초·중등에 차이가 있음을 고려하여 연계성과 중복성을 분석한 결론은 다음과 같다. 첫째, 교육과정 내용 체계화 구조를 분석하기 위한 연계성과 중복성의 준거 유형들을 개발하였다. 연계성은 '분절된 위계형'과 '나선의 위계형'으로 나누어 볼 수 있다. 중복성은 '반복형'(상), '재현형'과 '심화형'(중간), '치환형'과 '생략형'(하) 등으로 구분할 수 있는데 중간 정도의 중복성을 보일 경우 연계성이 높은 것으로 나타났다. 둘째, 초·중·고 내용을 비교한 결과, '인간발달과 가족' 영역에서 심화형 중복성을 나타내어 높은 연계성을 보이며, '가정생활과 안전'에서는 '안전' 개념이, '자원관리와 자립'에서는 '생애설계' 개념에서 낮은 연계성을 보였다. 셋째, 교육과정 성취기준을 분석한 결과, 초등에 비해 중등의 '가정' 내용은 난이도와 교과 내용의 양의 증가폭이 매우 큰 것으로 나타났다. 전체적으로 심화형 중복성을 보이며 연계성이 높아 체계적으로 교육과정을 구성하고 있으나 '가정생활' 분야의 핵심 개념 가운데 '안전'과 '생애설계'는 학교급 간의 연계성이 낮은 편이었고 '생활문화'와 '관리'는 중간 정도의 연계성을 보이며 '발달'과 '관계'는 높은 연계성을 나타내고 있었다. 나선형 교육과정으로 교과의 내용을 구조화 할 때는 초등과 중등의 내용을 유기적으로 연계할 필요가 있다. 이를 위해서는 실과와 기술·가정 각각의 학교급별 교과 지식체계를 구성하는 특성들을 고려한 핵심적인 개념을 중심으로 해야 하고, 적정한 분량 및 난이도를 고려해야 하며, 적정한 내용 중복의 정도를 고려해야 하고, 동일 학교급 내에서 동일 주제의 반복을 최소화 할 필요가 있다.
