Contamination levels of pathogenic microorganisms in 145 cases of beef, which were distributed in Gwangju province, had been investigated in each distributed stage and also monitored by general bacterial count and E coli count index. General bacterial count of beef from the slaughterhouse was 10$^4$cfu/g less than the level of promotion(10 cfu/$\textrm{cm}^2$) and E coli count index was also under the level of 10$^2$cfu/$\textrm{cm}^2$ recommended level of the ministry of agriculture and forestry. Pathogenic microorganisms were detected from 23.2% of samples in the consumption stage, 12.5% in the slaughtering stage and 5.6% in the transporting and processing stage. Staphylococcus aureus was isolated in the largest number and its ratio was 9.0%, listeria monocytogenes 5.5% and salmonella spp 1.4%. There were no samples that bacteria had been detected dually. E coli O157:H7 and campylobacter jejuni were not isolated. In raw and chilled beef, isolation rate of pathogenic microorganisms were 13.3% and 16.5% each. Especially in raw beef, L monocytogenes was. isolated in 3 samples among 30 cases (10%) and S aureus in one sample (3.3%). According to a scale of meat store, isolation rates of pathogenic microorganisms were different. It was 28.6% in the small-scale meat store and 16.7% in the large-scale meat store each. Four cases (16.7%) of S aureus were isolated in the large-scale meat store and seven cases (20.0%) of L monocytogenes and 2 cases (5.7%) of salmonella spp were isolated in the small-scale meat store. S aureus was isolated in two places among 10 feeding facilities of the elementary school. This result shows that the sanitation of elementary school feeding facilities is so poor and more careful policy consideration is needed. Eleven strains of S aureus isolated showed ${\beta}$-hemolysis on blood agar, 1 strain ${\alpha}$-hemolysis, and 1 strain ${\gamma}$-hemolysis. Isolated strains of L monocytogenes were reconfirmed in 560 bp by PCR. Conclusively, these results show that the sanitary condition in the stages of slaughtering, transportation-processing and consumption influences the degree of pathogenic microorganisms contamination in beef severely It is necessary to apply thoroughly hazard analysis critical control point in a process of beef distribution and also to develop rapid test methods for microorganism diagnosis. This effort is very important for the supply of safe and clean meat from farm to table and helpful for the improvement of public health.

Significant soil erosion and water quality degradation issues are occurring at highland agricultural areas of Kangwon province because of agronomic and topographical specialities of the region. Thus spatial and temporal modeling techniques are often utilized to analyze soil erosion and sediment behaviors at watershed scale. The Soil and Water Assessment Tool (SWAT) model is one of the watershed scale models that have been widely used for these ends in Korea. In most cases, the SWAT users tend to use the readily available input dataset, such as the Ministry of Environment (MOE) land cover data ignoring temporal and spatial changes in land cover. Spatial and temporal resolutions of the MOE land cover data are not good enough to reflect field condition for accurate assesment of soil erosion and sediment behaviors. Especially accelerated soil erosion is occurring from agricultural fields, which is sometimes not possible to identify with low-resolution MOD land cover data. Thus new land cover data is prepared with cadastral map and high spatial resolution images of the Doam-dam watershed. The SWAT model was calibrated and validated with this land cover data. The EI values were 0.79 and 0.85 for streamflow calibration and validation, respectively. The EI were 0.79 and 0.86 for sediment calibration and validation, respectively. These EI values were greater than those with MOE land cover data. With newly prepared land cover dataset for the Doam-dam watershed, the SWAT model better predicts hydrologic and sediment behaviors. The number of HRUs with new land cover data increased by 70.2% compared with that with the MOE land cover, indicating better representation of small-sized agricultural field boundaries. The SWAT estimated annual average sediment yield with the MOE land cover data was 61.8 ton/ha/year for the Doam-dam watershed, while 36.2 ton/ha/year (70.7% difference) of annual sediment yield with new land cover data. Especially the most significant difference in estimated sediment yield was 548.0% for the subwatershed #2 (165.9 ton/ha/year with the MOE land cover data and 25.6 ton/ha/year with new land cover data developed in this study). The results obtained in this study implies that the use of MOE land cover data in SWAT sediment simulation for the Doam-dam watershed could results in 70.7% differences in overall sediment estimation and incorrect identification of sediment hot spot areas (such as subwatershed #2) for effective sediment management. Therefore it is recommended that one needs to carefully validate land cover for the study watershed for accurate hydrologic and sediment simulation with the SWAT model.

원격진료는 정보통신기기를 활용해 의료정보를 주고받는 의료 혁신으로 인식되고 있지만, 사실상 오프라인의 여건에 따라 그 적용이 다양하게 나타난다. 예를 들어, 우리나라에서는 원격진료 시행의 기초 단위인 각 시군의 행정권에 따라 같은 의료권에 내에서도 원격진료는 차별적이다. 이에 본 연구에서는 강원도 원격진료 사례를 통해 원격진료의 지역적 차별성의 원인을 알아보았다. 더 나아가 이러한 차별성은 정보격차와 연관성이 있어 원격진료로 인해 유발되는 정보격차의 문제에 대해서도 고찰하였다. 본 연구의 주요 결과는 다음과 같다. 첫째, 원격진료의 도입과 더불어 행정 인력의 증원, 실질적인 행정 책임자에 대한 경제적 보상, 원격진료 기기에 대한 교육 등이 제대로 마련되지 않아 이를 수용할 수 있는 지역만이 원격진료를 활용하고 있는 것으로 나타났다. 둘째, 원격진료의 차별적 활용은 지역의료의 최고 결정자라 할 수 있는 시장 혹은 군수, 그리고 보건소장의 관심 여부와 연결된다고 할 수 있다. 셋째, 공중보건의는 원격진료의 실질적인 수행자 역할을 하고 있지만, 원격진료에 실시에 반대하고 있는 의사회와의 관계, 실질적인 지역의료 여건의 개선 미비 등으로 원격진료에 대해 회의적 입장인 것으로 드러났다. 넷째, 원격진료 활용의 지역적 차별성으로 인해 나타나는 정보격차는 아직까지 가시적인 것은 아닐뿐더러, 다른 차원의 격차(의료격차, 지역격차 등)로 전이되지 않았다고 판단되나, 앞으로 원격진료를 기반으로 하는 다양한 서비스가 이루어질 것을 예상한다면 이에 대한 적절한 대책이 필요할 것으로 보인다.

The main purpose of these studies was the improvemen of nutritional supply and of the future physical coditions. The two groups which were regional difference were chosen and research for the nutritional status of elementary school students. The nutritional status of lunch-box between one elementary School of 98 students in the 6th year grade(hence-forward it was called "A-Group"), located at the center of Masan City, being provided the milk and the other elementary School of 134 students in the 6th year grade(hence-forward it was called "B-Group"), located in the small farm and fishing villages of Kusan-myun, Euichang-kun, Kyungnam province, were seweyed from the period of Nov. 20, 1986 to Dec. 4, 1986 and conclusion were as follows: 1. Nutritional status of lunch-box 1) It is indicated that in the case of A-Group, the nutirtional intake except animal protein and vitamin A were lower than the Recommended Daily Allowances of Korenas and in the case B-Group, was also lower than except vitamin A respectively and especially in both groups, the percentage of Fe was lowest and intended difference between A Group and B was that B-Group in the intake of calorie, fat, Ca, Fe and etc were lower than A-Group. 2) The total calorie-intake was short of the extent to approx. 83.8% as compared to the RDA. On the viewpoint at ratio of intake of caloric nutrients, A-Group appeared to be 69.5 : 16.5 : 14 and B-Group, 77.5 : 19.5 : 13 in order carbohydrate, protein and fat. As a result of the above ratio, B-Group depended upon carbohydrate as a staple food more than A-Group. It can be considered that the total calorie-intake is short, and that the amount of lunch-box was greatly insufficient for taking optimal nutrition. 3) Calorie, carbohydrate, vitamin B, and niacin were taken nutrition from a staple food and protein from at similar ratio of staple and subsidiary food and fat, Fe, vitamin A, vitamin B1, adn vitamin C were mainly taken from a staple food. It was indicated that B-Group was higher at the supply-ratio by a staple food than A-Group. 3. The realities of improvement of physical conditions The improvement of physical conditions of the two groups were lower in accordance with Korea Children's Growth Standard, but B-Group was inferior to A-Group. 4. Seeing that the total intake of nutrition being taken at lunch time was lower as campared to the RDA intakes between the two Groups were remakably different, a lot of efforts should be made to improve the calorie-intake for the purpose of the farm and fishing villages. For balanced intake of nutrition, selection of foods and various cooking ways are important, therefore, throughout the expansion of the lowest stratum of elementary schools for milk-supply, high-quality protein, fat, Ca, vitamin B2 and etc should be supplied to the growing students. That can narrow the gaps of the intake of nutrition and physical condition between the students who live in cities and the students who live in the country.

전북지역 자동차산업 입지는 1990년대 초반 양적성장단계에 접어든 완성차업체의 저렴한 생산공간 확보전략과 정부의 선도기업 입지에 의한 지역균형발전 개발정책에 의해 이루어졌다. 그 결과 부품산업의 기반 없이 완성차업체가 입지한 후 부품 및 소재업체가 입지하는 반대되는 발전 패턴을 취하고 있기 때문에 취약한 지역산업의 구조적인 문제점을 보이고 있다. 우선, 지역 부품산업의 계층적인 구조가 정립되지 않아 효율적인 분업생산체제를 갖추지 못하여 많은 부품을 외부지역에 의존하고 있다. 그리고 대부분의 부품업체는 특정 완성차업체에 전속되어 있으며, 지역 부품산업의 대부분은 단순 임가공을 필요로 하는 저부가가치 업종으로 이루어져 있다. 마지막으로, 다른 지역에 비해 상대적으로 연관산업의 집적도가 낮아 기업유치 경쟁력이 낮은 문제점 등을 가지고 있다. 자동차산업을 지역산업으로 특화시켜 지역경제발전을 도모하기 위해서는 연관산업의 공간적 집적을 이루어 생산과정의 유연화를 창출해야 할 것이다. 최근 자동차산업은 적기조달방식과 모듈생산의 진전으로 완성차업체와 부품업체간의 지리적 근접성이 중요한 입지결정 요인으로 작용하고 있으며, 모듈생산방식은 기존의 공장에서 시도되기 보다는 새롭게 개발된 공장에서 주로 시도되고 있는 것으로 나타나고 있다. 따라서 지역단체는 우호적인 기업환경의 조성과 적극적인 기업유치전략을 통해 모듈화된 부품공급이 가능하도록 집적화된 산업단지의 육성을 도모해야 할 것이다.

The purpose of this research is to conserve of golden decoration(Jikgeumdan) of Chima(skirt) and Jeogori(Korean jacket) of the costumes excavated from Hangju Gi' tomb(17th Century) of Joseon dynasty$(1392{\sim}1910)$ and to focus on the development of conservation skill to prevent flakings of gold leaves in gilt paper strips. Up to the present, in case of golden decorations of costumes excavated from tombs of Joseon dynasty, some of gold leaves in gilt paper strips of costumes were flaked away by deterioration of adhesives in tombs. However, most of gold leaves were flaked away and totally lost by wet cleaning for eliminating contaminants after excavation. In order to prevent flaking, preliminary experiments for re-adhesion of gold leaves have been carried out. Firstly, simulation was performed using gold leaf which was available in the market. Adhesives used in this research were water-soluble adhesives(hide glue(cow, rabbit), glue made from air bladders of sciaenoid fish and Primal AC-3444 of acrylic emulsion) and solvent-soluble adhesives(acrylic adhesive Paraloid B-67 and B-72). Because of difficulty in wetting and spreading of adhesive solutions into the interface between gold leaf and Korean paper, water-soluble adhesives were not proper for adhesion of gold leaf and Korean paper. Solvent-soluble adhesives were easily infiltrated into interface between gold leaf and Korean paper and the adhesive force was also satisfied. From this result, the researchers chose more flexible Paraloid B-72$(Tg\;40^{\circ}C)$ 1% solution than Paraloid B-67$(Tg\;50^{\circ}C)$ for adhesion of gold leaf and Korean paper. Secondly, using Paraloid B-72 1% solution, the estimations of re-adhesions of gold leaves in gilt paper strips of Jeogori were carried out. When Paraloid B-72 1% solution was injected three times into the interface between gold leaf and Korean paper, the re-adhesion was most effective. On the basis of the results in these preliminary experiments, re-adhesions of gold leaves in gilt paper strips of Chima and Jeogori were carried out on condition of three times injections of Paraloid B-72 1% solution before wet cleaning. After wet cleaning, the most of the gold leaves were survived, which was confirmed by both the examination with the naked eye and the microscopic examination.

Background: Gastric cancer (GC) is the second cause of cancer related death in the world. It may develop by progression from its precancerous condition, called gastric atrophy (GA) due to gastritis. The aim of this study was to evaluate the accuracy of serum levels of pepsinogens (Pg) and gastrin-17 (G17) as non-invasive methods to discriminate GA or GC (GA/GC) patients. Materials and Methods: Subjects referred to gastrointestinal clinics of Golestan province of Iran during 2010 and 2011 were invited to participate. Serum levels of PgI, PgII and G17 were measured using a GastroPanel kit. Based on the pathological examination of endoscopic biopsy samples, subjects were classified into four groups: normal, non-atrophic gastritis, GA, and GC. Receiver operating curve (ROC) analysis was used to determine cut-off values. Indices of validity were calculated for serum markers. Results: Study groups were normal individuals (n=74), non-atrophic gastritis (n=90), GA (n=31) and GC patients (n=30). The best cut-off points for PgI, PgI/II ratio, G17 and HP were $80{\mu}g/L$, 10, 6 pmol/L, and 20 EIU, respectively. PgI could differentiate GA/GC with high accuracy (AUC=0.83; 95%CI: 0.76-0.89). The accuracy of a combination of PgI and PgI/II ratio for detecting GA/GC was also relatively high (AUC=0.78; 95%CI: 0.70-0.86). Conclusions: Our findings suggested PgI alone as well as a combination of PgI and PgI/II ratio are valid markers to differentiate GA/GC. Therefore, Pgs may be considered in conducting GC screening programs in high-risk areas.

This study was conducted to know the influence of air temperature and sunshine duration on yield, chemical component, pigment color difference and starch characteristics of two colored rice cultivars in the plain area of Yeongnam province in Korea. The $L^*$, $a^*$, and $b^*$ value of brown rice in Hongjinju and Josaengheugchal rice cultivars was significantly different at continuous cultivated years, 2015 and 2016. The $L^*$, $b^*$ value of two colored rice was significantly increased in 2016 compared to 2015. The $a^*$ value of Josengheugchal rice cultivar was also significantly higher at 2016 than at 2015. It can be noticed the $a^*$, $b^*$, $L^*$ values in Josaengheugchal varied more than those in Hongjinju. Air temperature during ripening period in 2016 was higher than 2015, especially minimum temperature was too high to proper maturation for rice quality. In Josaengheugchal rice cultivar, sunshine duration after heading was longer in 2016 than in 2015. On the contrary, Hongjinju rice cultivar was ripened under condition of insufficient sunshine duration in 2016. The short growing duration by high temperature and long shiny duration made the lack of pigment for Josaengheugchal brown rice. In Hongjinju rice cultivar, shorten sunshine duration and higher night temperature were the source of the pigment deficiency. The grain size of rice which produced in 2016 was bigger than that of 2015 in both rice cultivars. The 1,000 grain weight of rice from 2016 was also bigger than that of 2015. Head rice ratio was high in the rice cultivars produced in 2015. Protein of milled rice in 2016 was more decreased than that of 2015 in Josaengheugchal rice cultivar, it showed reverse result in Hongjinju rice cultivar. Amylose contents of milled rice in 2016 were more decreased than that of 2015 in Hongjinju rice cultivar. Branch chain length distribution of amylopectin was shown a distinct difference between Josaengheugchal and Hongjinju rice flours by each produced year. Josaengheugchal rice cultivar produced in 2015 had a higher amount of short chains than that of 2016 rice starches. In Josaengheugchal rice cultivar, the pasting temperature and peak, trough, breakdown, final viscosity increased in rice flour which produced at 2016, whereas the setback viscosity and peak time showed lower value than those of rice from 2015. The most pasting properties (except of setback viscosity) of rice starch in Hongjinju rice cultivar grown in 2015 were higher than those of rice cultivar produced in 2016.
