Sewon was a new type of private academy established by a class landed Confucian scholars known as sarim. During Joseon dynasty, sewon had dual functions as a shrine and a place of learning. The site plan of seowon appeared mainly two types of site plan according to the indications of the age and school. This paper was done to analyze the site plan and construction history of Simgok seowon with historical materials and excavation investigation result. Simgok seowon is dedicated to Jo Gwang-jo(1482～1519). This private Confucian academy was founded in 1605 as a small shrine, which was destroyed in 1636. Thereafter, when the shrine received a royal warrant naming as Simgok seowon in 1650, the new site for the seowon was chosen, which is currently located in Gyeonggi-do Yongin-si Sanghyeon-ri 203. Since then, buildings of Simgok seowon was constructed and repaired couple of times. Through the investigation, it was found that the site plan of Simgok seowon was originally a type of ‘jeonjaehudang’, that is, dormitory building between the lecture hall and the outer gate, or dormitory building is in front and lecture hall is in behind.

21세기 지식기반사회에서 기술 발전 속도는 가속화되고 있으며 조직 목표를 달성하는데 영향을 줄 수 있는 시장, 거버넌스 및 사회적 가치의 미래 모습에 대한 불확실성이 증대하고 있다. 이러한 기술과 사회 발전의 가속화 및 증가하는 불확실성에 대응하기 위해서 다양한 미래사회 전망을 바탕으로 미래유망기술을 도출하는 기술예측의 필요성은 더욱 중요해지고 있다. 기술예측에는 다양한 예측 방법론이 이용 가능하나 예측의 목적 및 재원 등에 따라 선택되어야 한다. 델파이 방법이 오랫동안 주로 사용되어 왔지만 최근에는 시나리오 또한 많이 활용되고 있다. 시나리오는 사회, 경제 및 정치 등의 환경요인의 복잡성과 불확실성을 폭넓게 고려할 수 있으며 미래의 다양한 모습을 이야기 식으로 전달하기 때문에 매우 효과적인 전략적 도구로 활용된다. 전세계적으로 진행되고 있는 기후변화, 화석연료의 고갈 등으로 세계 각국은 신재생에너지에 대한 높은 관심을 갖고 기술개발 및 보급 등을 적극적으로 추진하고 있다. 하지만 신재생에너지 분야의 가용잠재량은 지역적으로 큰 편차가 있으며 기술적 진보, 환경규제 및 화석 연료의 가격전개와 밀접하게 연관되어 있어 그 발전추이를 예측하기 어려운 면이 있다. 이에 본 연구는 이러한 불확실성을 반영하여 신재생에너지 분야에 대한 다양한 미래 시나리오를 작성하고 시사점을 도출하였다. 향후 본 연구의 시나리오 기반의 예측 프로세스를 국가과학기술예측에 활용함으로써, 기존의 델파이 위주의 단정적 예측의 단점을 보완한 전략적 예측을 강화할 수 있을 것으로 전망된다.

Keunsemal, Sinhang-ri, Dunpo-myeon Asan-si,Chungcheongnam-do is where the former President of Korea, Yun, Bosun was born. The houses of Yun, Il-Sun, Yun, Je-Hyung, Yun, Seung-Gu, and where the former President Yun was born are designated as cultural assets by the Korean government. The three houses of the Yuns are located in the center of the village and the size is much different from regular houses since they were created as large scale house of nobilities during the Chosun Dynasty. Along with the three Yun houses and other houses in the village show a great history and tradition of the history and modern times. Unlike other traditional village arrangement, this village was created during the end of Chosun Dynasty and extended into the modern times. From the village, you can see the changes in architecture within the 200 years from traditional Korean-style houses to modern houses. This investigation is a research / analysis of the architectural characteristics of Keunsemal, Sinhang-ri, Asan-si. People can observe changes in the different types of architectural forms of houses based on the history of Korea and time periods. Within the village, there are large scale house of nobilities which were built during the late Chosun Dynasty, common people’s houses, farmhouses which were built during the modern times, common people’s houses during the industrialization period, and modern houses with backyards. The village of Keunsemal, Sinhang-ri, Asan-si is a very special cultural asset for Korea because the houses in the village show a clear architectural process of change in styles of houses for Korean history.

This study surveyed the reading discomforts and the reasons for discomfortable reading of the safety and health information (texts and icons) presented on the agricultural vehicles/machines, pesticides, fertilizers, and feeds. Eighty seven people residing in rural area participated in the survey interview. Questionnaire survey showed that the most discomfortable product in reading the texts was pesticides. Forty three (49%) among participants had very-discomfortable or discomfortable in reading the texts used in the label of pesticides, and the main reason for the discomfort was small text size. The reading discomforts in reading the texts (varied from 4 point to 19 point and presented in 50 cm reading distance) showed different pattern according to the age groups. Three age groups (50s, 60s and older than 70s) showed a similar discomfort pattern, but different from the group of 30s and 40s. Forty four people (51%) had a problem in understanding the meaning of the icons and the main reasons were the small size and the difficulty in inferring the meaning of the icons. Thus, the more detailed and practical guidelines for the presentation format, particularly about the text heights and the size of icons, are required. Also, more comprehensive research is needed to investigate the readability and legibility of texts and icons.

Mould growth can deteriorate indoor air quality in buildings. To alleviate the problems in the built environment, accurate understanding of the risk factors associated for mould infestation is required. This study aims to evaluate current status of mould growth problems in residential buildings in Korea. Both the physical characteristics of buildings and the behaviour of occupants have been studied as risk factors. In this study, a questionnaire survey has been conducted randomly on a national basis. A total of 314 completed questionnaires were collected and processed for statistical analysis. The relationship between mould growth and activity factors was analyzed. As a result, about 30% of residential buildings in Korea reported mould problems. However, the types of residential buildings did not show a statistically significant difference in the ratio of mould problems.

This study was intended to determine the maneuverability of the vessel CHARMBADA. When the rudder angle was at 10˚, 20˚ and 30˚, the maximum advance by slow, half and full ahead were varied in the range of 523.6-131.3m, 528.8-177.2m and 530.6-219.7m, respectively. The maximum transfer was 799.9-181.3m, 792.1-232.8m and 807.7-316.9m, respectively. The turning circle ability was better during starboard turning. When the rudder angle was 10˚, 20˚ and 30˚, variation in the maximum advances was 392.0m, 245.0m and 153.0m. The maximum transfer was 528.0m, 339.0m and 218.0m, respectively based on the regression equations. As the rudder angle became bigger, the maximum advance or maximum transfer became smaller by the exponential function. The advance inertia took 127sec, 145sec, 181sec each until the vessel speed was 7.0konts, 12.0konts, 17.0konts. The static inertia took 245sec, 269sec, 300sec each until the vessel speed was under 2.0konts and the advance distance was 114.4m, 181.2m, 197.0m each. Accordingly, the static inertia was inclined to increase to scale according to the increase in vessel speed. For the CHARMBADA, the smaller the rudder angle was, the much bigger the turning circle became due to adhesion to the skeg, thereby lowering the vessel's turning ability.

There are differences of Cadmium (Cd) urinary concentration which is considered as indicator of renal tubular dysfunction in other countries, so we have reviewed domestic epidemiological data and suggested Korean health based guidance value (HBGV) for Cd to improve an efficiency of risk management. We decided to apply the WHO calculation model which considered the relationship between dietary intake and Cd concentration in urine sample. It is determined that Cd concentration 2.5 ug/g creatinine in urine as the prevalence of renal tubular dysfunction based on epidemiological data, because there is no renal tubular dysfunction and injury/lesion such as proteinuria at the concentration of 11.63 ug/g creatinine which is the highest Cd concentration in urine from the domestic epidemiological data. It is identified that the ratio between the Cd dietary consumption (8.3~10.4 ug/day) and Cd urinary concentration (0.38 ug/g creatinine) in Korean adult who predicting never been exposed to Cd are 21.8~27.3 and then it is applied to the corresponding model suggested by WHO. Also it is applied that 10% of bioavailability and 50% of excretion rate of absorbed to body (the ratio is 24) were assumed. The estimate of daily Cd consumption level which begins tubular dysfunction is 1 ug/kg bw/day, so we suggest the Korean provisional tolerable weekly intake (PTWI) as 7 ug/kg bw/week.

到2000年为止, 中国政府正在与40多国家和地区缔结或进行FTA谈判。中国现在以地区均衡发展为目标，全国性的更换和采购了社会间接设备。尤其是随着2008年北京奥运会，2010年上海世博会，广州亚运会等国际型的活动即将到来，对韩国企业来说,　参加中国政府采购市场的非常好的机会。 因此，为了进军中国政府采购市场了解中国招标投标制度是非常重要的。 关于政府采购市场的市场接近(Market Access)方面，中国一直采取了建设以及机械设备市场的进入壁垒，而且中央和地方政府都有着不同的特点和管理机制。比如，不同的申报和许可制度，地方保护主义等。中国政府已经制定和实施了2000年 <招标投标法>，2003年 <政府采购法>。　 因此，本论文是研究和分析中国<招标投标法>，<政府采购法>实施以后，在招标投标过程中的透明度和规范化方面的问题和变化。为了进一步分析其问题和变化采取了案例调查方法。　 本人搜集了庞大的有关资料以及亲自到中国去进行实地考察。 在中国进行招标投标时，大部分政府和企业之间的行为。一般来说，有中国特点的招标机制上不是按照有关法律和政策来决定，而是大部分按照个人的人情和关系网来决定中标的可能性较大。 本论文的特点是第一，有关研究中国投标招标的制度的非法性，非合理性方面，可以说头一次进行实地考察。第二，在韩中FTA谈判方面给韩国政府提供了实质性的资料。与此同时，给韩国企业提供了战略性的进军方案。

목적: 본 연구에서는 제조물책임법(PL법)에 관한 안경사 인식도를 연구하고자 한다. 방법: 광주광역시 광산구, 전라남도 나주시, 함평군, 목포시, 강진군, 해남군에 개설한 안경원 50곳에 근무하는 개설 안경사와 종사 안경사 중 설문지를 성실히 응답해주신 117명에 대해서 조사했고, 조사결과는 통계분석 프로그램 SPSS 17.0을 사용하였다. 결과: 대부분의 개설 안경사 및 종사 안경사의 PL법에 대한 인식도가 2003년 조사보다 향상되었으나, 2009년 조사에서도 62%가 인식전환이 없는 것으로 나타나, PL법의 시행 여부, 안경사 인식전환 및 숙지사항 등에 대해서 모르거나, 관심 없는 것으로 판단된다. PL법에 대한 상담 사례가 있었느냐 물음에 2003년 조사 당시는 없다고 응답했었다. 그러나 2009년 조사 결과 상담사례가 13명 있는 것으로 나타났다. 또한 개설 안경사가 종사 안경사 보다 PL법의 대처방안에 대한 교육 필요도가 높은 것으로 나타났다. 결론: PL법에 대비한 제품의 결함 사례 분석 연구가 체계적으로 수행되어야 하고, 안경사들의 소비자에 대한 태도변화 및 인식전환이 필요한 것으로 사료된다.

Aflatoxin (AF) and Ochratoxin A (OTA) are carcinogenic and possible carcinogenic mycotoxins respectively produced by Aspergillus spp or Penicillium spp. The study for contamination survey and proposal for reduction of mycotoxin in red pepper were carried out. 192 samples were collected at such various stages and markets as pre/post-harvest stages, internet shopping mall /super-market and small stakeholder mill/geographically indicated company. As only 2 samples were positive for aflatoxin, so contamination rate was 1.04%. In the meanwhile, contamination rate for ochratoxin A was 21.88% and a various amount of OTA was detected in 42 positive samples. 6 samples were found to be contaminated at higher level than 5 μgkg−1 for ochratoxin A, which was established recently as a maximum permissible limit in korea. There was no difference in degree of contamination with regard to cultivation type because any mycotoxin was not found at all in both organically and conventionally grown red pepper. But, there was statistically significant difference in the process of manufacturing. Finished products were OTA-contaminated at a level of 2.32 ± 6.54 μgkg−1(mean ± SD), even though OTA was not detected in deep frozen red peppers right after long term storage. And contamination for OTA was a level of 0.33 ± 0.91 μgkg−1(mean ± SD) in red paprika powder after uv sterilization, while the contamination for OTA was 2.78 ± 4.49 μgkg−1(mean ± SD) in non-uv sterilized powder. In addition, our investigation shows that higher OTA contamination occurred in some of famous brand products sold in super-market and domestic products than products collected through on-line shopping or from small stakeholder mills and imported products respectively, however, difference was not statistically significant.

본 연구에서는 국가의 연구개발활동조사에서 기업연구개발활동 통계에 대한 효과적인 산출방법을 제시하고자 하였다. 이를 위하여 국내 ; 외 연구개발 통계 방법을 조사한 후 이를 토대로 우리나라에서 기업연구개발활동에 대한 자료의 수집 및 분석에 대한 개선방안을 제시하였다. 대부분의 국가에서 대기업은 전수조사, 소규모 기업은 표본조사를 수행하고 있으나, 우리 나라에서는 연구소 등록법인에 대하여 전수조사를 행하고 있다. 전수조사는 비용이 많이 들고 비표본오차로 인하여 모집단에 대한 체계적인 추정이 불가능하다는 문제점이 있다. 현재 산업기술진흥협회에 등록된 연구기관의 수가 20,000개를 넘어서고 있어 전수조사는 한계에 다다른 것으로 생각되어 표본조사 도입에 대한 타당성과 방법론을 중점적으로 검토하였다. 먼저, 표본조사의 타당성을 평가하기 위하여 현재 전수조사를 통해 수집된 자료를 이용하여 표본조사를 수행한 결과를 비교 분석하였다. 산업별(24개), 그룹별(8개)로 구분하여 216개 셀별로 모집단수/표본수를 곱하여 산정(셀별추정법)한 결과, 전수 통계치와 거의 동일하게 나타났다. 따라서, 산업별, 그룹별로 세분하여 모집단수/표본수를 곱하여 추정하는 셀별추정법이 타당한 것으로 평가할 수 있다. 이상의 분석결과를 토대로 조사설계 방안을 제시하면 다음과 같다. 직전연도 조사기업은 직전연도 연구개발비 수준과 기업종류(대기업, 벤처기업, 중소기업), 그리고 산업에 따라 셀을 분할한다. 대기업, 연구개발비 수준이 높은 기업 등 주요한 셀에 대하여는 전수조사를 실시한다. 나머지 셀에 대하여는 각 셀별 연구개발지출의 분포가 동질적이기 때문에 표본 추출방법은 단순임의추출법(SRS)을 사용한다. 다만 전년도 미계상된(또는 미포함된) 기업에 대하여는 신규 대형 연구소 진입 등을 고려하여 규모비례확률추출법(PPS)을 고려하는 것이 바직할 것으로 판단된다. 일부 기업들이 특정 항목에 대한 자료를 제공하지 않는 항목무응답의 경우, 누락된 자료에 대하여는 대체기법(Imputation Algorithm)에 따라 이를 추정한다. 이러한 표본조사방법은 전수조사에서 발생하는 비표본오차를 해소하고, 자료 수집비용 및 소규모기업의 행정적 부담을 경감할 수 있다는 장점이 있다. 향후 연구에서는 좀 더 구체적인 조사방법론을 강구할 필요가 있으며, 이와 함께, 연구개발에 대한 다양한 측면의 정보를 수집하기 위해 새로운 설문지를 개발할 필요성이 있다.

현대의 산업은 점차 분야가 다양해지고 기술이 첨단화되며, 고객의 요구사항이 복잡해지고 있다. 이에 따라 제조업에서는 초정밀, 고신뢰도가 요구되어지고 있는 실정이다. 제조업 분야의 핵심 기술인 SPC기법 중에서 누적합(CUSUM) 관리도는 공정의 작은 변화에 대해서 민감하다는 특징 때문에 첨단 산업인 반도체나 화학공정 등에서 활용도가 높은 관리도 기법이다. 하지만 복잡한 이론 체계로 인하여 사용편리성이 떨어진다는 단점이 있다. 본 논문에서는 누적합 관리도의 이론적 전개에 관한 체계적인 조사연구를 통해 누적합 관리도의 복잡한 이론 체계를 이해하는데 도움이 되고자 한다.

Currently food-borne disease is being increased at outdoor food services including hotels and restaurants. Speedy and convenient practical monitoring techniques to determine hygienic conditions are needed. This study was designed to verify correlation of direct ATP (Adenosine Tri-Phosphate) examination method using ATP bioluminescence and surveillance with check-list by inspector. Hygienic status of personal hygiene (hands), kitchen utensils (knives, chopping boards, kitchen towels, cap openers, food storage containers, and blade of slice machines), facilities and equipments (refrigerator handles, worktables, and sinks) in five major hotels in Seoul were examined. The result of personal hygiene of hotels was relatively better than other inspection items (46.6 points in personal hygiene, 40.2 points in kitchen utensils, 40.3 points in facilities & equipments). In ATP inspection, kitchen utensils and facilities & equipments were relatively clean comparing with personal hands data (40.8 ± 6.77 RLU/cm²). After correlation analysis of surveillance in hygienic status points and ATP value, all results showed negative and high correlation. The surveillance data and ATP results investigating personal hygiene, kitchen utensils and facilities & equipments were highly correlated. The ATP examination method which shows real-time identification could be considered as an appropriate method to alternate current check-list dependent safety management in food services including hotels.
