건설산업은 발주자가 생산활동(시공) 이전에 소요되는 비용을 예측하여 수급자에게 도급주는 형식을 취한다. 따라서 공사비 예측은 건설 프로젝트 전 단계에 걸쳐 수차례 이루어져야 하며, 발주자와 수급자 모두에게 중요하다. 그러나 국내의 경우 단가물량내역 완료전 공사비 예측은 실적자료를 이용한 면적당 단가방식을 벗어나지 못하고 있으며 이를 보완하기 위한 정형화된 절차와 방법이 미비한 것이 현실이다. 이에 본 연구는 국내 공공 아파트 사업 주동을 대상으로 수량기반 공사비 분석 방법인 면적형 세대별 수량분석 방법을 제안하고 데이터베이스를 구축한 후 유효성과 세목수량 예측중심 공사비 예측방법의 적용성을 확인하였다. 이로써 건설프로젝트 전체 라이프사이클에 대한 공사비정보의 일관성 있고 상호 연계된 관리가 가능할 것으로 예상되며, 예측 결과가 세목 수량과 단가의 곱으로 이루어져 각종변경 및 연계확보, 시점의 변화, 제도의 변화에 탄력적으로 적용될 수 있다. 따라서 본 연구는 건설 공사비정보를 수량기반 데이터 형태로 집 관리할 수 있는 방법을 제시하고 그 효용성을 확인하였다는데 그 의미가 있다.

This study is historical research on the relationship between the Changes of the Form of costume and the recognition of the beauty of the body from prehistorical period to Ch'ing Dynasty in Chinese female costume. In figure painting a significant point was to describe the spirit of the figure so Chinese painters were less interested in ideal body pro-portion or body shape than Westerns. But idealized beauty of the female body existed and changed keeping abreast with the form of costume in each period. In the prehistorical period Wemen fasten waist belt so enabled to distinguish upper part of the body from lower one. "Locust-forehead moth-eyebrows(蝗首蛾毛)" recorded in "the Book of odes(詩經)" was the canon of beaty and Wemen tried to make their forehead broad and square from Zhou Dynasty to the Wei Jin periods. From the age of Civil War to han Dynasty Slender waist was loved so waist was tightly fastened and hemline became broader. in the course of that time Plump body in big cloth with broad sleeve emerged but that was less significant than Tang Dynasty. During Wei Jin and the Southern/Northern Dynasty undergo disruption and division they admired Taoist images. Loose fitting style with handkerchief hemline and broad sash belt was prevailed while miserable life was reflected gaunt face and lean body. Suk Dynasty also preferred a slim and long body silhouette. The style was presented extremely high waist line long and narrow sleeve slim and long skirt which expressed dynamic and straight image. The culture of Tang Dynasty was open and diverse and that character enabled blod decolletate revealing body line by tight fitting and special make-up-Social background of uion and stabilization made female body extremely plump full face. full breast and hips with most erotic image. The period of Kaiyuan Tianbao fashioned mannish disguise presented androgynous image. Five Dynasty and Song Dynasty restored standard body type so upper garments concealed neck and bust high waist line lowered which represented refined and simple outfit. But another eroticism emerged as foot-binding in Song Dynasty. For the sake of covering up deformed top of the feet and ankle gaiters and arrow shaped shoes were devised. During Ming Ch'ing Dynasties body shape became more slim weak and young causing to escort instinct that reflects 'Lust' or 'Mundanity'.

To ensure the microbiological safety of food items prepared after cooking process, this study was aimed to identify the hazards related with cooked foods donated to foodbanks through quantitative microbial analysis. Five foodbanks located in Incheon and Gyeonggi area among government-dominant foodbanks were surveyed from February to June, 2007. Manager, recipient, donator, type and quantity of donated foot and facility and equipment were examined for the general characteristics of foodbank. The time and temperature of food md environment were measured at steps from after-production to before-distribution, and the microbial analysis was performed mainly with indicator organism and major pathogens. The amount of cooked foods donated to each foodbank was about 20 to 30 servings and consisted of 80% of total donated foods. Only three foodbanks had separate offices for foodbank operation and four institutions had at least one temperature-controlled vehicle. The flow of donated foods was gone through the steps; production, meal service and holding at donator, collection by foodbank, transport (or holding after transport) and distribution to recipients. It took about 3.8 to 6.5 hours at room temperature from after-production to before-distribution. Only aerobic plate counts (APC) and coliforms were found in microbial analysis. The APC after production were relatively high in $8.2{\times}10^5,\;7.4{\times}10^5,\;6.9{\times}10^5$ and $4.2{\times}10^5 CFU/g$ while $2.8{\times}10^6, \;9.4{\times}10^5,\;1.0{\times}10^6$ and $5.4{\times}10^5CFU/g$ before distribution in mixed Pimpinella brachycarpa, mixed chard mixed amaranth and mixed spinach, respectively. The levels of coliforms in mixed chard and mixed spinach were complied with the standards of the Ministry of Education and Human Resources Management The level of APC in boiled pork was increased from $< 1.0{\times}10 CFU/g$ to $4.0{\times}10^2 CFU/g$. One of delivery vessels was shown $6.2{\times}10^3 CFU/100 cm^2$ in APC, which was over the standards for environment. One of serving tables also showed the high level of $1.2{\times}10^3 CFU/100 cm^2$ in APC and $6.6{\times}10^2 CFU/100 cm^2$ in coliforms. These results suggest the sanitary management of holding at donator and the time-temperature control are key factors to ensure the safety of cooked foods donated to foodbank.

Objective: To investigate the effects of different pilot-drilling methods on the biomechanical stability of self-tapping mini-implant systems at the time of placement in and removal from artificial bone blocks. Methods: Two types of artificial bone blocks (2-mm and 4-mm, 102-pounds per cubic foot [102-PCF] polyurethane foam layered over 100-mm, 40-PCF polyurethane foam) were custom-fabricated. Eight mini-implants were placed using the conventional motor-driven pilot-drilling method and another 8 mini-implants were placed using a novel manual pilot-drilling method (using a manual drill) within each of the 2-mm and 4-mm layered blocks. The maximum torque values at insertion and removal of the mini-implants were measured, and the total energy was calculated. The data were statistically analyzed using linear regression analysis. Results: The maximum insertion torque was similar regardless of block thickness or pilot-drilling method. Regardless of the pilot-drilling method, the maximum removal torque for the 4-mm block was statistically higher than that for the 2-mm block. For a given block, the total energy at both insertion and removal of the mini-implant for the manual pilot-drilling method were statistically higher than those for the motor-driven pilot-drilling method. Further, the total energies at removal for the 2-mm block was higher than that for the 4-mm block, but the energies at insertion were not influenced by the type of bone blocks. Conclusions: During the insertion and removal of mini-implants in artificial bone blocks, the effect of the manual pilot-drilling method on energy usage was similar to that of the conventional, motor-driven pilot-drilling method.

Epidemiological studies have shown the association between transportation of live animals and the potential transmission of infectious disease between premises. This finding was also observed in the 2014-2015 foot-and-mouth disease (FMD) outbreak in Korea. Furthermore, slaughterhouses played a key role in the global spread of the FMD virus during the epidemic. In this context, in-depth knowledge of the structure of direct and indirect contact between slaughterhouses is paramount for understanding the dynamics of FMD transmission. But the social network structure of vehicle movements to slaughterhouses in Korea remains unclear. Hence, the aim of this study was to configure a social network topology of vehicle movements between slaughterhouses for a better understanding of how they are potentially connected, and to explore whether FMD outbreaks can be explained by the network properties constructed in the study. We created five monthly directed networks based on the frequency and chronology of on- and off-slaughterhouse vehicle movements. For the monthly network, a node represented a slaughterhouse, and an edge (or link) denoted vehicle movement between two slaughterhouses. Movement data were retrieved from the national Korean Animal Health Integrated System (KAHIS) database, which tracks the routes of individual vehicle movements using a global positioning system (GPS). Electronic registration of livestock movements has been a mandatory requirement since 2013 to ensure traceability of such movements. For each of the five studied networks, the network structures were characterized by small-world properties, with a short mean distance, a high clustering coefficient, and a short diameter. In addition, a strongly connected component was observed in each of the created networks, and this giant component included 94.4% to 100% of all network nodes. The characteristic hub-and-spoke type of structure was not identified. Such a structural vulnerability in the network suggests that once an infectious disease (such as FMD) is introduced in a random slaughterhouse within the cohesive component, it can spread to every other slaughterhouse in the component. From an epidemiological perspective, for disease management, empirically derived small-world networks could inform decision-makers on the higher potential for a large FMD epidemic within the livestock industry, and could provide insights into the rapid-transmission dynamics of the disease across long distances, despite a standstill of animal movements during the epidemic, given a single incursion of infection in any slaughterhouse in the country.

Objectives The goal of this review was to investigate clinical, experimental and literature studies of Korean medicine on atopic dermatitis (AD) of Korean children in Korean medicine literature, seeking for the better research methods for more effective treatments. Methods Electronic investigations were practiced on AKOP (The Association of Korean Oriental Pediatrics, http://www.akop.or.kr) to collect theses which were published by J Pediatr Korean Med. The key word 'Atopy' was used for searching to ensure that every related thesis was collected. The publication date was limited from 1996 to 2016. The selected literatures were assessed mainly according to distributions of study type, publication year, scale, treatment and its efficacy. Results 55 papers were selected from 59 studies. In these collected 55 related theses, there were 29 experimental studies (52.73%), 18 clinical studies (32.73%), 8 review studies (14.55%). In the 29 experimental studies, there were 20 studies (68.97%) using NC/Nga mouse as subjects. The mite antigen was used to trigger AD by 8 studies (27.59%). The studies have been utilizing DNCB and DNFB instead of mite antigen since 2011. All the experimental studies showed that the Korean medicine was effective in AD. In total 18 clinical studies, 3 studies (16.67%) were case reports, only 1 thesis (5.56%) was conducted by case control study and the rest were case series studies. 7 studies (38.89%) of 18 studies diagnosed AD according to Hanifin and Rajka's diagnostic criteria (1980), only 1 study (5.56%) according to the Korean standard and the rest 10 studies (55.56%) didn't mention diagnostic criteria. 12 clinical studies (66.67%) showed efficacy in treating AD. There were 10 studies (55.56%) only employing internal treatments and 1 thesis (5.56%) didn't mention the exact prescription. Naesowhajungtang-kamibang, Saenghyeoryunbue-um were used 3 times (16.67%) as the internal medicine respectively. 5 theses (27.78%) were combined with acupuncture therapy. Hegu (LI4), Sanyinjiao (SP6) were used in 4 theses, and Taichong (LR3), Quchi (LI11), Zusanli (ST36) in 3 theses. The number of acupoints chosen from The Spleen meridian of Foot-Taiyin was the largest. There were 8 review theses. 2 were about the foreign oriental medicine, 3 were about the external medicine or external treatment methods, and 3 other studies were about severity scoring systems, the methodological study in the latest clinical study, overview for pattern and results of herbal medicine-derived AD clinical researches. Conclusions The experimental studies and clinical studies showed the effectiveness of Korean medicine treatments. However, this study still needs improving by conducting more comparative studies and using better research methods, in order to find more effective treatments to improve clinical efficacy.

Background: African swine fever virus (ASFV), classical swine fever virus (CSFV), and porcine reproductive and respiratory syndrome virus (PRRSV) are still prevalent in many regions of China. Co-infections make it difficult to distinguish their clinical symptoms and pathological changes. Therefore, a rapid and specific method is needed for the differential detection of these pathogens. Objectives: The aim of this study was to develop a multiplex real-time quantitative reverse transcription polymerase chain reaction (multiplex qRT-PCR) for the simultaneous differential detection of ASFV, CSFV, and PRRSV. Methods: Three pairs of primers and TaqMan probes targeting the ASFV p72 gene, CSFV 5' untranslated region, and PRRSV ORF7 gene were designed. After optimizing the reaction conditions, including the annealing temperature, primer concentration, and probe concentration, multiplex qRT-PCR for simultaneous and differential detection of ASFV, CSFV, and PRRSV was developed. Subsequently, 1,143 clinical samples were detected to verify the practicality of the assay. Results: The multiplex qRT-PCR assay could specifically and simultaneously detect the ASFV, CSFV, and PRRSV with a detection limit of 1.78 × 10⁰ copies for the ASFV, CSFV, and PRRSV, but could not amplify the other major porcine viruses, such as pseudorabies virus, porcine circovirus type 1 (PCV1), PCV2, PCV3, foot-and-mouth disease virus, porcine parvovirus, atypical porcine pestivirus, and Senecavirus A. The assay had good repeatability with coefficients of variation of intra- and inter-assay of less than 1.2%. Finally, the assay was used to detect 1,143 clinical samples to evaluate its practicality in the field. The positive rates of ASFV, CSFV, and PRRSV were 25.63%, 9.36%, and 17.50%, respectively. The co-infection rates of ASFV+CSFV, ASFV+PRRSV, CSFV+PRRSV, and ASFV+CSFV+PRRSV were 2.45%, 2.36%, 1.57%, and 0.17%, respectively. Conclusions: The multiplex qRT-PCR developed in this study could provide a rapid, sensitive, specific diagnostic tool for the simultaneous and differential detection of ASFV, CSFV, and PRRSV.
