본 연구에서 한우를 공란우로 사용하여 OPU 방법으로 가장 더운 계절의 hot season과 선선한 cool season의 두 계절의 차이에 따른 생성된 난포의 수, 난자 회수율, 난자 등급율, 수정율 및 배반포 발달 능력을 분석하여, 두 계절이 공란우의 번식 능력에 미치는 영향에 관하여 조사하였다. 1. 계절의 영향이 OPU 공란우의 난포 생성 수에 미치는 결과는 난포 생성 개수는 1154개(18.32±2.26), 971개(15.41±3.34)로 hot season 그룹이 유의적으로 높은 것을 알 수 있었다(p＜0.05). 2. 계절에 따른 난자 수 및 난자 회수율은 hot season 그룹의 475개(7.54±3.14), 41.16%로 cool season 그룹 448개(7.11±3.42), 46.14%와 비교하여 유의적인 차이가 없었다(p＜0.05). 3. OPU를 통하여 회수된 두 계절별 난자 등급은 Grade A는 Hot season 그룹 110개(1.75±1.86), Cool season 그룹 63개(1.00±1.46)로 hot season 그룹이 cool season 그룹과 비교하여 유의적으로 높았다(p＜0.05). 하지만 다른 등급인 Grade B는 87개(1.38±1.60) vs. 97개(1.54±1.39), Grade C는 166개(2.63±2.43) vs. 170개(2.70±2.04), Grade D는 112개(1.78±2.65) vs. 118개(1.87±1.86)로 hot season과 cool season 간의 유의적인 차이를 보이지 않았다(p＜0.05). 4. 계절에 따른 체외 수정 후의 수정률은 hot season과 cool season 각각 242(66.67%)와 209(63.3%), 배반포 발달율 214(58.95%) vs. 188(56.97%)로 수정률과 배반포 발달율은 유의적인 차이가 없었다(p＜0.05). 본 연구의 결과로 계절에 따른 영향에 의해 공란우의 난포생성수와 A등급의 난자 출현율에서 유의적인 차이를 보였다. 하지만 나머지 등급의 난자 출현율, 수정률 및 배반포 발달율은 차이가 없는 것으로 보아, 계절의 차이로 인한 한우 공란우의 번식 능력에 미치는 영향은 미비하다고 판단된다.

The main object of this study is to investigate the collection characteristics of wet-type rotating porous disk system experimentally. The experiment is carried out to analyze the pressure drop and collection efficiency for the present system with the experimental parameters such as system inlet velocity, stage number, tube diameter, inlet concentration, etc. In results, for the present system, at 5 stage and υin=1.8 m/s, the pressure drop becomes significantly lower as 64 mmH2O in comparison with that of the conventional wet type scrubber (Venturi scrubber, over 250 mmH2O). The collection efficiencies increase with higher inlet velocity showing 92, 95.7, 98.4%, while SO2 removal efficiencies decrease with increment of inlet velocity as 80, 65, 50% at υin=1.08, 1.44, 1.8 m/s and tube diameter Dt=10 mm, respectively. The present system is to be considered as an effective compact system for a simultaneous removal of particle/gas phase pollutants from marine diesel engines.

Today all nations in the world focus on remaining competitive advantage by adding high values to their fashion businesses. The most typical example of such added value is fashion collection. In case of London Fashion Week, which is among the world’s top 4 most famous fashion collections where more than 5,000 journalists and buyers from 25 nations can be expected every season, it has great contribution to the economic wealth of London. It induces consumption of 20 million GBP and economic production effects of one hundred million GBP. According to Joo (2009), one of the main purposes of fashion collections can be defined as the invigoration of international marketing and the creation of consumption demand. Fashion collections lead to increased direct sales and consumption demand by developing new products based on leading fashion trends that are presented in the collection. The so-called Big four collections in Paris, Milan, New York and London have their own Country of Origin (COO) image, which represents each country, cities, brands, products and services. For example, Paris collection has been established as luxury image with hand-made and Haute Couture. Not only fashion collection but also fashion brands have applied specific country characteristics to their fashion brand’s image. This serves as a critical factor of competitiveness that communicates an integrated image of brands to the customers. Also, within the purchase decision-making process, consumers consider COO as an important element. Therefore, organizer of fashion collections as well as brands that engage in such should consider COO as a key factor. Most of the previous studies about fashion collections focused on content analyses. For example, Joo (2009) compared characteristics and current situations between four major overseas cities’ collections and Seoul collection. Additionally, there are studies about fashion style, trend, design and textile. Characteristics of color change in 1990s fashion collection (Kim & Kim, 2007) and an analysis of design of hats and fashion images in collections (Jeong & Jeong, 2008) have been conducted as well. Previous studies related to COO mainly focused on the product (Bilkey & Nes, 1982) and how the image of the producing country affects product evaluation. Thus, the purposes of this study are 1) to examine of fashion collection’s COO and fashion brand image effects on brand evaluation and purchase intention, 2) to analyze differentiation factors of COO image, brand evaluation, purchasing intention on Seoul, New York and Paris collection. We surveyed Korean, American and French who have experience in their own country’s fashion collection and used SPSS 21 for data analysis. Fashion collection’s COO and brand image has a great effect on brand evaluation and purchase intention. Moreover, it seems to increase the purchase intention by affecting brand evaluation. Therefore, the results of the study are as follows. First, we can confirm that the better the fashion collection’s COO and fashion brand image, the higher brand evaluation and purchase intention is. Second, when assessing fashion collection’s COO image and fashion brand image, brand evaluation and purchase intention differ according to Korea, US and French national stereotypes. This study goes beyond the general product-centric COO studies and introduces the fashion collection’s COO that can be valuable research in terms of contribution not only to academia, but also to the industrial field.

In this study, the changes in collection efficiencies due to the time changes of activated carbons were ascertained, and in order to identify the magnitude of adsorption, the before-use and after-use iodine adsorption values were analyzed. In addition, as a result of examining the characteristics of continuous process and non-continuous process and as a result of investigating whether the emission standards would be maintained, the continuous process and printing facilities were seen as not being able to maintain the emission standards. Also were found, in the case of non-continuous process,–taking into consideration the special nature of the job –for 4Ø palletized charcoal, a collection efficiency near 50% was shown even after 96 hours. Also, when the inlet concentration was about 300ppm, it is thought that the emission standards would be maintained if the activated carbons are replaced within at least 96 hours in the case of 4Ø palletized charcoal and the use was deemed pointless in the case of carbon. The results of this study are expected to provide assistance in selecting replacement periods for activated carbons and in selecting absorbents at the project sites, and are expected to be of significant help in the selection of precipitators that can collect total hydrocarbons for compliance of the emission standards.

The main object of this study was to investigate the collection characteristics of wet-type cyclone with wall cavity. The experiment was executed to analyze the characteristics of pressure drop and collection efficiency for the present system with the experimental parameters such as water spray, water spray type, inlet velocity etc. In results, for the present system of wet-type, the pressure drop represented 35 mmH2O, while in dry-type 33 mmH2O showing lower 6% at vin=21 m/s. In case of vin=21 m/s and water spray 200 mL/min, the collection efficiency of the present system became significantly higher as 96.8% comparing to that of the conventional wet-type scrubber. Additionally, for 200 mL/min, SO2 removal efficiencies decreased with the increment of inlet velocity representing 75.0, 62.5, 50.0%, at vin=6, 9, 12 m/s, respectively.

환경대기 중의 휘발성유기화합물을 채취할 때 사용하는 샘플링 방법은 백을 이용한 샘 플링 방법과 흡착관을 이용한 샘플링이 대표적이다. 본 연구에서는 실제 대기시료를 이 용하여 두 샘플링 방법을 동시에 진행하여 비교하고자 하였다. 시료의 채취방법에 따른 회수율 정도를 알아보기 위해, 청국장을 조리하면서 발생하는 시료를 채취하는 과정에서 실험을 진행하였다. 그 결과, 유기산의 회수율이 백 샘플링보다 흡착관을 이용한 샘플링 에서 평균적으로 98.6 %의 percent difference (PD)를 나타내는 것을 확인하였다. 카보닐 계열과 방향족은 19.2와 34.3 %로 비교적 적은 차이를 나타냈다. 각 성분 중에서 butyl acetate는 0.50 %로 가장 낮은 수치를 보였고, TMA도 마찬가지로 비교적 낮은 수치를 기록하였다(2.13 %). 이러한 결과는 현장 조건에서 채취방식의 중요성을 확인해 주었다

Being a country with diverse geophysical features and climate, Myanmar scores as one of the richest biological reservoirs in Asia. Myanmar has a rich diversity of flora and fauna, about 68 swallow tail butterflies represent 12% of the world total making it the fifth richest country in the world. Myanmar has a lot of protected areas such as national parks, wildlife sanctuaries and botanical gardens. Among them best to be observed for insects collection are Alaungdaw Kathapa National Park in Sagaing region, Popa Mountain National Park in Mandalay, Mount Victoria National Park and Nat Ma Taung in Chin state. Forest and vegetation types, wildlife, location and access to these parks were presented.

This is presented general consideration for the establishment and management of germ-plasm collection. The topics addressed concern the establishment of the collection, the acquisition andentry of the plants into the collection, germplasm health issues, a presentation of the various conserva-tion methods available to germplasm collections and collection management procedures. Many impor-tant varieties of field, horticultural, root and tuber crops are ether difficult or impossible to conserve asseeds or reproduce vegetatively. Genetic resources of such plant species are generally conserved in fieldgenebanks. field genebanks provide easy and ready access to conserved material for research as well asfor use. For a number of plant species the alternative methods have not been fully developed so that theycan be effectively used. For many species, field genebank is one of the components of complementarystrategy for the conservation of vegetative germplasm. Despite the importance that field genebank playsin conservation of plant genetic resources, the concepts and scientific principles for establishing andmanaging field genebanks are not very well understood by many plant genetic resources workers. Plant-ing a few plants or tree does not constitute a field genebank. There is more science to it that is needed forcontinue maintenance of genetic diversity in the accessions planted in the field as well as to utilize thediversity being thus maintained. It is well recognized that an appropriate collection and conservationstrategy for a particular plant gene pool requires a holistic approach, combining the different ex situ con-servation techniques available in a complementary manner. Ex situ methods are options available for thedifferent genepool elements that are cultivated species, including landraces and modern varieties, wildrelatives, weedy types, etc. Vegetative germplasm has been maintained in field genebanks may be lostbecause of mite infestations or microbial infections. The level of duplication may also depend on theholdings of other genebanks. Accessions available at another genbank may require fewer duplicates thanunique samples

Collection of ecological data such as the temporo-spatial distribution of a species is very difficult, due to broad distribution over large areas, phenology, and lack of resources for field survey. Citizen science, which is a cooperative scientific endeavor between researchers and interested citizens, is ideal for collecting large-scale ecological data. However, lack of proper equipment, species identification, and/or communication between researchers and participants are hindrance for a successful citizen science project. Here, we introduce the concept and methods of large-scale ecological data collection using smartphone apps. Most of the ecological data typically consist of sound or video recording, picture, geographic coordinate, and notes. There are several apps that can collect some or all of these ecological data. Furthermore, the result of a survey can be reported to researchers using Google Docs. The data collected by non-specialists can be validated by cross-checking of the survey report by Google Docs and the ecological data sent by apps. Finally, we report the results of a citizen science project in which temporo-spatial distributions of cicada species in Korea were studied via smartphone apps and Google Docs.

지난 1970년이래 헝가리자연사박물관의 북한지역 탐사를 통해 채집조사되어 보관된 표본을 대상으로 검경한 결과 북한산 잎말이나방과 12종이 추가로 분류 동정되어 보고한다. 이중 2종(Notocelia rosaecolana Doubleday, Rhopobota ustomaculana Curtis)은 북한지역에서는 처음으로 보고되는 북한미기록종이었다. 이외에 보고되는 10종은 주로 기존문헌에 목록에만 포함되어 있어 정확한 분포정보들이 없어왔던 종들로 금번연구를 통해 새로운 분포지가 기록되는 종들이다. 본 연구에서는 금번에 보고되는 2종의 북한미기록종과 새롭게 채집지가 확인된 10종의 목록을 정리하여 보고하며 각 종별로 채집지기록, 국내외 분포 및 기주식믈정보 등을 제시하였다.

To collect entomopathogenic fungi we sampled soils from two different cultural types of farm which are conducting conventional culture and organic culture, and non-crop land. Forty-seven soil samples were collected from 9 provinces. Among them, 7 samples were collected from non-crop land, 6 samples were from organic farm and 34 samples were from conventional culture farm. Insect-bait method using Galleria mellonella and agar plating method were conducted to collect entomopathogenic fungi. Collection of entomopathogenic fungi using insect-bait method was highest in non-crop land as 7.1 mycotic cadavers per soil sample followed by organic farm with 3.6 and conventional farm with 3.3. Result from agar plating method showed the highest colony forming unit (cfu) was in organic farm followed by non-crop land, but cfu in conventional cultivating farm was a half compared with the non-crop land.

Particle collection efficiency and air cleaning capacity were tested for the two-stage electrostatic precipitator for use in indoor air cleaning systems. A wire-plate type ionizer was used as a particle charger and a dielectric film consisted of polypropylene (or polyethylene) coated metals and zigzagged metal electrodes was used as a particle collector in the electrostatic precipitator. Both particle collection efficiency and air cleaning capacity increased as increasing the applied voltage on the charger and the collector, and furthermore, as increasing the collector film width (i.e. collection area). Air cleaning capacities estimated by the product of particle collection efficiency and air flow rate were quite well consistent with the experimental ones with a proportional constant of 0.964. Ozone concentrations emitted from the charger at the applied voltages of 5.0 and 5.2 kV were less than 0.05 ppm, indoor ozone standards of UL 867-2002, KS C 9314 and SPS-KACA002-132. For the air flow rate of 11.7 m³/min, the applied floor area of 48.2 m² could be obtained when 5.2 kV and 6.0 kV were applied on the ionizer and the collector, respectively and the collector of two 15 mm polyethylene dielectric films was used.

Ganoderma lucidum, a popular medicinal mushroom, has been used in China for longevity and health promotion since ancient times. Recently it is being used as a good pharmaceutical material or functional bio-material. Total 106 strains was cultured at temperature(25 ℃, 30 ℃ ,35 ℃) to study cultural properties of Ganoderma lucidum. Then the mycelium growth was digitized in the average diameter. With the result, Ganoderma lucidum strain has the optimum growing temperature at 25 ℃ with 25 strains, 30 ℃ with 70 strains and 35 ℃ with 11 strains. The 84strains were cultivated in wood for investigating the cultivation properties of Ganoderma lucidum. With the result, 70mm~90mm of the pileus diameter (major axis, mm) and 70mm-80mm of pileus diameter (minor axis, mm) was measured after one year cultivation. And 1,000-2,000 ㎟ of strain took the most the area (major axis x minor axis). The 30-40mm of stipe length,1time of harvesting and volume was 200g~400g took the most. 10cm-15cm of the pileus diameter (major axis, mm), 5cm~7.5cm of pileus diameter (minor axis, mm) and 15-20mm of thickness was measured after 2 year cultivation. And 50~100 ㎟ of strain took the most the area (major axis x minor axis). The 5-10mm of stipe length, 2 times of harvesting and volume was 200g~400g took the most. we are selected a middle model through this result. phylogenetic relationships was drawn based on the ITS sequence analysis in Ganoderma lucidum.

This study was conducted based on a comparative analysis of design-specific features prevalent in the Women's Wear Collection S/S 2011. As the method of this study, the denim styles were classified by various fashion design factors consisting of silhouette, fit, color, and textile fabric, which were extracted from an image database. The properties of denim fabrics associated with each fashion image were investigated to inform fabric development and washing. The results of the study show that the dense and glossy surface of the denim fabric represent a modern trend, which can be achieved by blending lyocell, tencel and rayon or by using different textiles, such as lightweight plain weave and satin instead of twill. For casual look, various washing effects were utilized jean's casual feeling like freedom and activities, while in a modern image, washing effects was restricted. And a glossy textile offers a simple modern look. The Modern image represents a simple H-silhouette and wide or straight fit in bottoms as well. Brightness can be adjusted by washing-induced bleaching. High brightness gives an elegant image, while low brightness makes a casual image. The purpose of this study is to configure a database for the development of design in the growing women's casual wear market. In addition, This study, in which the elements for specific fashion image-making were analyzed, can be used as a reference for developing denim style and fabric.

This study was performed in order to determine optimum flushing solution using the direct embryo collection (DEC). Donors, at random stages of the estrous cycle, received a CIDR. 7 days later, 200 mg FSH was treated with 40, 30, 20, 10 mg FSH levels in declining doses twice daily by intramuscular injection for 4 days. On the 3 day administration of FSH, 25 mg was administered and CIDR was withdrawn. After FSH injections were complete, donors were artificially inseminated twice at 12 hr intervals. The donor cattle received 250 GnRH at time of 1 insemination and embryos were recovered 8 days after the 1 insemination. Embryo collection from superovulated donors were performed to flushing by DEC and conventional method. As a results, the average number of recovered embryos were significantly higher as 19.11.40 with DEC method than 12.00.44 with conventional embryo collection method, respectively (p<0.05). Also, The average number of transferable embryos were significantly higher (p<0.05) as 15.81.72 with DEC method than 6.90.35 from conventional embryo recovery procedures. Meanwhile, number of recovered embryos and number of recovered transferable embryos following the number of flushing times until 6 flushing were significantly higher as 8.60.53 and 8.60.53 from 2 flushing time than other groups (p<0.05). No. of Ear. B stage embryos were significantly higher as 3.90.90 and 3.90.90 with 2 flushing time in total collected embryos and transferable embryos (p<0.05). Com M stage embryos were significantly higher as 3.71.00 in 2 flushing time and as 2.20.76 in 3 flushing time for recovered embryos (p<0.05). In transferable embryos, Com. M stage embryos were significantly higher (p<0.05) as 3.71.00 in 2 flushing time and as 2.20.76 in 34 flushing time, also. No. of degradation embryos was significantly higher as 2.20.72 in 5 flushing time, On the other hand, degradation embryos was not observed in transferable embryos (p<0.05). In conclusion, these results suggest that DEC method should effective methods for production of in vivo embryos using less flushing solution following perform until 4 flushing time than conventional embryo collecting method. Also, it might be effectively collection of transferable embryos following more less procedure times compared to conventional embryo recovery methods.

This study was performed in order to simplify the operation and minimize stress of donor and be readily available in the field with low cost and high quality embryos using the Direct Embryo Collection (DEC). Donors, at random stages of the estrous cycle, received a CIDR. 7 days later, 200 mg FSH was treated with 40, 30, 20, 10 mg FSH levels in declining doses twice daily by intramuscular injection for 4 days. On the 3rd day administration of FSH, 25 mg was administered and CIDR was withdrawn. After FSH injections were complete, donors were artificially inseminated twice at 12 hr intervals. The donor cattle received 250 GnRH at time of 1 st insemination and embryos were recovered 8 days after the 1st insemination. Embryo collection from superovulated donors was performed to flushing by non-surgical methods of 3-way, 2-way and DEC (l-way). The average number of recovered embryos were 11.250.63, 12.50.65 and 11.750.48 from operations of 3-way, 2-way and DEC methods, respectively. There were no significant differences among the embryo collection methods. Also, The average number of transferable embryos were 6.250.48, 7.250.48 and 7.250.63 from each embryo collection procedures. The number of transferable embryos was no differences among the 3-way, 2-way and DEC methods, respectively. Meanwhile, the ratio of transferable embryos for all recovered embryos from DEC methods was higher as 61.7 % than 55.6 %, 58 % from methods of 3-way, 2-way. And the flushing solution required for recovering embryos by DEC method was significantly lower as 0.280.32 1 than 1.80.12 1, 1.750.10 1 from 3-way, 2-way methods (p<0.05). Also, the time required for recovering embryos by DEC methods was significantly lower as 272 min than 513, 452 min, respectively (p<0.05). In conclusion, these results suggest that DEC method for embryo collection may be effectively used for production of in vivo embryos using less flushing solution and, it might be effectively available in the field compared to conventional embryo recovery methods using 3-way or 2-way balloon catheter.

The objective of this study was carried out to evaluate the efficiency of sperm collection methods on the post-thaw viability of cat semen. The cat semen was collected by artificial virginal (AV) and electronic ejaculate (EE) methods. The composition of semen extender was consisted of Tris-buffer supplemented with 20% egg yolk and 1% P/S antibiotics in Ext I, and more added 8% glycerol, 1.0% Equex STM paste of total volume in Ext II. The collected semen was adjusted the concentration and then diluted in Ext I for optimal concentration. The diluted semen was cooling to 5℃ temperature in refrigerator for at least 2 hrs and then diluted stepwise with Ext II for at least 1 hrs. After an equilibration for 1 hrs, the cooled semen was packaged in 0.5 ml straw and then freezing on the LN2 vapor over 5 cm above from LN2 and then immersed directly in LN2 for cryopreservation. The frozen semen was thawed in 38℃ water for 15 sec and then evaluated the motility, viability, and morphology. Post-thaw semen were calculated the motility by SMI (sperm motility index). The live-dead sperm was evaluated by Eosin-B and morphological evaluation was by Diff-quik kit staining. The post-thaw concentration (89×106 /ml vs. 128×106 /ml), viability (22.6±10.6% vs. 37.1±26.1%), morphological normality (27.0±50.2% vs. 45.6±123.0%) of EE and AV groups were not significant different, but the post-thaw motility was significant lower in EE than that in AV group (53.1±3.6 vs. 73.6±5.7) (p<0.05). In conclusion, semen collection methods did not significant different between EE and AV groups except of post-thaw motility and so both semen collection methods could be applied in feline semen collection methods.
