The farming type in Korea is predominantly a small farm managed by family members. This study mainly examines the current usage of the website of family farms as a management tool for small farm business and discusses the strategies for effective utilization of the website. A county that currently employs governmental project of information system was purposely selected. Among all the websites operated by small farm businesses in that county, websites of which purpose is introduction of the business, advertisement, or e-business were included for analysis; it yielded total seven websites, The study was conducted with two phases; on-line website analysis and interview with business owners. The websites were analyzed based on four categories; content, interface, design, and site management. With regard to the content of the websites, the lack of connection between domain names and product names was found. Moreover, the problem relevant to site management was shown as low utilization of bulletin boards and delayed upload of new information. However, design and interface were comparatively well presented. Business owners reported that the motivation to initiate the websites was mostly supports from the governmental project for the agricultural information system. The barriers to effective management of websites were found i) business owner's misinterpretation of business website with e-business ii) very limited opportunity for website management education in small farm business, and iii) lack of regional infrastructure for information system. Based on the findings, this study suggests as followed; i) construction of infrastructure should be preceded to make effective management for websites; ii) education for website management should include small business management strategies as well as computer skills, iii) the education should be provided in diverse ways considering subject's characteristics iv) small farm business owners should be informed that their websites could play a role only to provide information about the products and hand over the practical load for e-business to retailing web sites such as portal shopping mall; and v) wives' participation should be encouraged.

Mushrooms have a long history of use in traditional medicine, and hundreds of novel constituents in mushrooms with miraculous biological properties have been identified recently. Although diverse effects for medicinal use of mushrooms such as anticancer activity are proven, their reversal activities of drug resistance in cancer cells was rarely reported so far. In the search for novel medicinal use of mushrooms, we tested the multidrug resistance (MDR) reversal activities of diverse mushrooms collected from Korea. Among, the mushroom extracts tested, Cantharellus cibarius (M02) and Russula emetica (M12) revealed MDR reversal activities of paclitaxel in the P-glycoprotein (Pgp)-positive HCT15 and MES-SA/dX5 cancer cells, but not in the Pgp-negative A549 and MES-SA cancer cells. In addition, these mushrooms also enhanced the cytotoxicity of doxorubicin, another well-kwown Pgp-associated anticancer drug against MES-SA/DX5 cells, but not against MES-SA cells. Meanwhile, the cytotoxicity of cisplatin, a well-known Pgp-non-associated anticancer drug, was not affected by the mushrooms all the cells tested. From these results, we suspected that some ingredients of M02 and M12 have Pgp-associated MDR reversal activities.

Cotton is the major fiber crop in Pakistan that accounts for 2% of total national gross domestic product (GDP). After picking of cotton, the dry stalks are major organic waste that has no fate except burning to cook food in villages. Present research focuses use of cotton stalks as feedstock for biochar production, its characterization and effects on soil characteristics. Dry cotton stalks collected from agricultural field of Bahauddin Zakariya University, Multan, Pakistan were combusted under anaerobic conditions at $450^{\circ}C$. The physicochemical analysis of biochar and cotton stalks show higher values of % total carbon, phosphorus and potassium concentrations in biochar as compared to cotton stalks. The concentration of nitrogen was decreased in biochar. Similarly biochar had greater values of fixed carbon that suggest its role for carbon sequestration and as a soil amendment. The fourier transformation infrared spectroscopic spectra (FTIR) of cotton stalks and biochar exposed more acidic groups in biochar as compared to cotton stalks. The newly developed functional groups in biochar have vital role in increasing surface properties, cation exchange capacity, and water holding capacity, and are responsible for heavy metal remediation in contaminated soil. In a further test, results show increase in the water holding capacity and nutrient retention by a sandy soil amended with biochar. It is concluded that cotton stalks can be effectively used to prepare biochar.

Melatonin regulates circadian rhythms and reproduction changes in seasonally reproductive mammals through binding to high-affinity, G-protein-coupled receptors. Small Tail Han sheep that has significant characteristics of high prolificacy and nonseasonal ovulatory activity is an excellent local sheep breed in P. R. China. The exon 2 of the ovine melatonin receptor 1a (MTNR1A) gene was amplified and a uniform fragment of 824 bp was obtained in 150 ewes of Small Tail Han sheep. The 824 bp PCR product was digested with restriction endonucleases Mnl I and Rsa I, and genetic polymorphism was detected by PCR-RFLP. Polymorphic Mnl I site was detected at base position 605 of the exon 2 of the MTNR1A gene. There were two kinds of genotypes in Small Tail Han sheep, AB (303 bp, 236 bp/67 bp) and BB (236 bp/67 bp, 236 bp/67 bp). The results indicated that genotype AA (303 bp, 303 bp) at Mnl I-RFLP site did not exist in non-seasonal estrous Small Tail Han sheep, which suggested that there was an association between genotype AA (303 bp, 303 bp) and reproductive seasonality in sheep. Polymorphic Rsa I site was detected at base position 604 of the exon 2 of the MTNR1A gene. Three kinds of genotypes were found in Small Tail Han sheep, AA (290 bp, 290 bp), AB (290 bp, 267 bp/23 bp) and BB (267 bp/23 bp, 267 bp/23 bp). Least squares means of litter size in the first parity and the second parity for genotype AA (290 bp, 290 bp) at Rsa I-RFLP site were 0.43 and 1.06 more than those for genotype AB (290 bp, 267 bp/23 bp) in Small Tail Han sheep.

A strain of Pepper mottle virus (PepMov) was isolated from chili pepper plants in Korea. In host range study, this virus, designated PepMoV-SNU1, shared most characteristics with PepMoV isolates reported previously. Thermal inactivation point ($45^{\circ}C\;to\;75^{\circ}C$) and dilution end point ($10^{-1}\;to\;10^{-4}$) of PepMoV-SNU1 showed differences depending on the propagation hosts. Cylindrical and pinwheel-shaped inclusions were always observed in pepper leaf tissues infected with the virus alone. Unexpectedly, a special structure of pinwheel shaped inclusion surrounded with unknown small spots was also observed in the leaf section when co-infected with a strain of pepper mild mottle virus. The partial sequence of coat protein gene and 3' untranslated region of PepMoV-SNU1 showed 98% identity with those of other PepMoV isolates. A primer pair derived from 3' end of the coat protein gene and poly A tail regions were designed. Optimal detection condition of PepMoV-SNU1 by RT-PCR was tested to determine appropriate annealing temperature and additional volumes of oligo-dT (18-mer), dNTP, and Taq polymerase. Under the optimized condition, an expected 500 Up PCR-product was detected in pepper leaves infected with PepMoV-SNU1 but not in healthy plants.

오늘날 유통구조의 변화는 오프라인에서 온라인으로 급격하게 수요가 변화해 가고 있다. 이러한 현상은 상품을 편리하게 구입하고자 하는 소비자의 심리가 반영되어 있다고 할 수 있다. 농산물 역시 내용물을 보호하려는 안전성과 소비자들에게 신뢰를 줄 수 있는 브랜드 및 디자인이 어느때보다 중요하게 인식되어지고 있다. 특히, 딸기 과채류는 다른 과채류에 비해 껍질이 얇아서 약한 충격과 흔들림에도 상품의 품질이 떨어지기 때문에 패키지의 지기구조나 소재에 안정성 영향을 많이 받는다. 또한, 직거래 유통이 많은 과채류다보니 생산농가의 열약한 환경 때문에 패키지디자인이 다른 상품에 비해 경쟁력이 떨어지는 것이 현실이다. 즉, 딸기 수요가 날로 증가하는데 비해 딸기패키지는 생산자와 소비자 욕구에 충족하지 못한다는 점이다. 딸기판매에 경쟁력 강화를 위해서는 패키지개발의 기초연구가 시급한 실정이다. 패키지요소(형태, 소재, 디자인) 조사 분석을 통하여 패키지의 문제점을 파악하고, IPA MAP(중요도, 만족도)분석을 통하여 생산자와 소비지가 추구하는 개선점을 파악하고자 한다.

A construction project is a designed product made up of labors, materials, and installations in the project positioned on the ground and may include the underground and ground section, and the section in water or on the water surface. It is a civil, industrial, transport, agricultural and rural development, infrastructure, or some other. A key phase in the life cycle of these construction projects is the implementation when building products are made directly with workers, equipment, materials, and managers. If there is a lack of management experience, information, and problem-solving solutions to tackle the risks faced by contractors, especially foreign ones, will fail in controlling the project's cost. This study was conducted with investigations, discussions, and evaluation of the factors that lead to cost overruns in the construction projects of international contractors in Vietnam. The principal component analysis (PCA) showed that those factors that influence cost overruns these construction projects fall into five general groups, including factors related to (i) the owners, (ii) the foreign contractors, (iii) the subcontractors and suppliers, (iv) state management, and (v) the project itself. Besides, the study proposes solutions to limit cost overruns in construction projects and improve the profitability of international contractors in Vietnam.
