Alteration in ion channel or transporter expression levels affects cell volume which is produced by movement of water and ion across the plasma membrane. In particular, aquaporin (AQP) channels among ion channels play a crucial role in movement of water across the cell membrane. This study was performed to identify whether AQP expression is changed in bovine follicular cystic follicles using microarray, RT-PCR and Western blotting analyses. In microarray data, AQP4 expression was decreased, whereas AQP7 was increased in cystic follicles. Additional experiments were focused on the AQP7 expression increased in cystic follicles. The microarray data was confirmed by semi-quantitative polymerase chain reaction (PCR) and Western blot analysis. AQP7 mRNA and protein expressions were significantly increased in the cystic follicles (p<0.05). Application of estrogen (10 μg/ml) to bovine ovarian cells showed a trend of increase in AQP7 expression. From these results, we suggest that the increase in AQP7 expression in cystic follicles may play an important role in movement of water in bovine ovary. In addition, AQP7, a aquaglyceroporin permeating water and glycerol, could be a good target in development of methods for the cryopreservation of bovine ovary.

The object of this study is to develop textile designs and fashion products based on the cultural resource of Jeju Bangsatop, which means a stone tower preventing misfortune and driving out evil spirits. The field surveys of 32 Bangsatops located at 17 villages in Jeju were conducted. As a result, unlike stone towers located in other regions, Jeju Bangsatops made with basalt. In addition, wood and stone birds, Dolhareungbang, and other sculptures are built on the tops. Jeju Bangsatops were classified into four types based on the body form of the tops: Conical, truncated conical, trapezoid, and irregular shaped Bangsatops. Jeju Bangsatops located in a area or a village are symmetrically arranged in direction of south and north, left and right, east and west, or face to face. The conical, truncated conical, and irregular shaped Jeju Bangsatops which are designated as folk cultural properties or which have the unique sculptures of stone birds and the statues of Dolhareungbang built on the tops were selected as motifs for textile pattern design. The 4 basic patterns of Jeju Bangstops were designed. The six creative textile designs were developed by the various repeat arrangements of the basic patterns and were printed on oxford cotton fabrics by digital textile printing (DTP) method. The sixteen products of wallets, bags, hats and shoes were actually made with the DTP fabrics, the DTP fabrics which were naturally dyed in gray and blue colors, or the DTP fabrics which were redesigned with textile crayon. Therefore, it is confirmed that Jeju Bangsatop could be very useful as a motif for the development of cultural products focusing on Jeju tourism souvenir market.

This study is to develop cultural products based on 'Jeju Choga', which means the traditional houses in Jeju. For the product development, old literature review, field surveys, and consumer surveys were employed. Through old literatures and field surveys, the unique and visual characteristics of Jeju Choga were confirmed: A thatched roof with lattice pattern, a side wall and fences with porous stones, a 'Jungnang' serving as a gate, and a 'Pungchai' preventing strong sola radiation and 'Ollai' meaning a narrow street in front of the Choga. As a results of consumer survey conducted before the development of products, consumers highly recognized and associated Jeju Choga as Jeju representative image. The six basic patterns of Jeju Choga were drawn and eight textile designs were created through the repeated arrangements of the basic patterns. Using the created textile designs and digital printing method, the eleven new fabrics with the patterns of Jeju Choga were developed. The various kinds of ten bags and tow wallets made with the new fabrics. As a result of consumer evaluation for the twelve products made in this study, the scores of preference and purchase intention were above the average work for the most products of them. In particular, the preference and purchase intention of the square shoulder bag, the big-size shopper bag, and the small-size cross bag were very positively evaluated. Therefore, it is confirmed that Jeju Choga could be very useful as a motif for the development of cultural products focusing on Jeju tourism souvenir market.

The average prevalence rate (PR) for foodborne disease outbreaks (FBDOs) in the first half (F-H) and latter half (L-H) of the decade from 2001 to 2010 in Korea was 14.0 and 16.9 per 100,000 population, respectively. The number of patients per outbreak of foodborne diseases (FBDs) in the F-H of that decade was 57.6 and in the L-H was 25.4 (p < 0.05). A comparison of the 2 periods covered in this study indicates that FBDOs in the L-H most frequently involved restaurants or delis (51.5% of total cases), and in the F-H, this involvement was noted in 34.0% of total cases (p < 0.01). The epidemic patterns of microbial FBDOs show that the overall incidence of outbreaks resulting from 5 of 8 key pathogens including Bacillus cereus (+1.6%), Campylobacter jejuni (+1.5%), Clostridium spp. (+0.7%), pathogenic Escherichia coli (+8.3%), and Norovirus (+14.4%) tended to be higher in the L-H than in the F-H of the decade from 2001 to 2010. Conversely, those caused by the other 3 key agents, including Salmonella spp. ( 9.2%), Staphylococcus aureus ( 2.8%), and Vibrio parahaemolyticus ( 6.4%) were significantly lower in the L-H than in the F-H of the decade. Moreover, in the decade between 2001 and 2010, the number of patients (n) and the PR for microbial FBD increased from the F-H (n = 13,346, PR: 5.6) to the L-H (n = 33,732, PR: 13.8) (p < 0.01).

Cows may suffer impaired ovarian function, often accompanied by reduced conception rates and increased embryonic loss. Cystic ovarian disease (COD) is one of the most frequently diagnosed gynecological findings in dairy cattle. It causes temporary infertility and is likely to affect reproduction as well as production parameters in cattle. Therefore, the purpose of this study was to determine the expression patterns of apoptosis (Bcl-2, Bax), implantation (E-cadherin) and immune related proteins (TNF-α, IL-10) in uterine endometrium of Hanwoo (Korean native cattle) with ovarian cyst and normal ovarian follicles. In the Western blot analysis, the expression of anti-apoptotic Bcl-2 protein was significantly higher in endometrium with normal ovarian follicles, whereas expression of pro-apoptotic Bax protein was significantly lower. Also, the expressions of E-cadherin and TNF-α proteins were significantly higher in uterine endometrium with normal ovarian follicles. On the other hand, the expression of IL-10 protein was significantly lower in uterine endometrium with normal ovarian follicles. Taken together, our results provided that the expressions of apoptosis, adhesion and immune related proteins in uterine endometrium with ovarian cyst were showed the aberrant patterns, and we suggest that different expression changes of these proteins may be affect to pregnancy ability of cattle.

The objective of this study is to investigate consumer preferences, perception and consumption patterns for fish products. To investigate the difference in consumer responses according to the characteristics of the population parameters, data were collected from the survey of 404 Koreans and analyzed. The results are as follows: First, the differences of age; for the question of the reason why do you eat fish products, the younger generation (20〜30s)’s most answer was‘The Taste’while the older age groups(40〜50s and over 60s)’most respond was‘For Health’. Second, the differences of sex; women relatively considered‘The Quality’of fish products more important than men when selecting the products. Whereas, men thought‘The Taste’of fish products more important than women when they choose fish products. In addition, when the bad news or hygiene accidents about fish products are reported on media, women reacted more negatively for fish products purchase than men. Third, the differences of family members; the respondents who lived with 3 or more family members showed higher preference rates about purchasing trimmed fresh fish at the store than respondents who lived with 2 or less family members. On the other hand, single households relatively bought processed fish products and RTE(Ready To Eat) fish products more than other family member groups. In addition, single households preference rates about eating fish products as a main dish were very high compared to other groups.

The objectives of this study were twofold: to analyze seasonal variation in nutrients and sestonic chlorophyll (CHL-a) in Asian lotic ecosystems, which are influenced by seasonal monsoon rains, and to evaluate multi-trophic level ecological stream health (ESH) in relation to stream morphology, land-use patterns, and water chemistry. We conducted physical, chemical, and biological surveys at 72 national streams and rivers, and at 65 reference streams. Water chemistry data indicated that ambient nutrient (N, P) levels were closely associated with land-use patterns and stream elevation, and that these, in turn, influenced both community structures of fish and stream health in general. In the watershed, total phosphorus (TP) was a key determinant of sestonic CHL-a, and the mass ratio TN:TP was determined by phosphorus (R2 = 0.63, P < 0.01) rather than nitrogen (R2 = 0.01, P > 0.05). Proportions of tolerant and omnivorous fish increased with nutrient enrichment and organic matter pollution, while proportions of sensitive and insectivorous fish decreased. The neural network modeling of a self-organizing map (SOM) suggested that clustering of trained SOM units reflected stream morphology, land-use patterns, and water chemistry, which influenced community structures and tolerances of top trophic level fish species in the ecosystem. Lotic ecosystem health, based on a multi-metric approach (MF-IBI model), was clearly demonstrated by a multivariate analysis (PCA); important factors were watershed characteristics (land-use patterns), nutrient levels (N, P), organic matter (BOD, COD) regimes, and biological components (trophic and tolerance guilds).

We demonstrate a simple and effective method to accurately position silicon nanowires (Si NWs) at desirable locations using drop-casting of Si NW inks; this process is suitable for applications in nanoelectronics or nanophotonics. Si NWs were assembled into a lithographically patterned sacrificial photoresist (PR) template by means of capillary interactions at the solution interface. In this process, we varied the type of solvent of the SiNW-containing solution to investigate different assembly behaviors of Si NWs in different solvents. It was found that the assembly of Si NWs was strongly dependent on the surface energy of the solvents, which leads to different evaporation modes of the Si NW solution. After Si NW assembly, the PR template was cleanly removed by thermal decomposition or chemical dissolution and the Si NWs were transferred onto the underlying substrate, preserving its position without any damage. This method enables the precise control necessary to produce highly integrated NW assemblies on all length scales since assembly template is easily fabricated with top-down lithography and removed in a simple process after bottom-up drop-casting of NWs.

This study investigated students' alternative conceptions of plate boundaries and their conception revision according to the pattern of students' reasoning. Participants were twenty-two 10th grade high school students. All participants were asked to draw the three types of plate boundaries and to explain their drawings. Nine students participated in the reasoning activity. To this end, a semi-structured interview was conducted during which key questions were asked for the students to individually answer. The key questions used in the reasoning activity were created, by utilizing questions used in the previous studies. The findings revealed that the alternative conceptions of plate boundaries were classified into three levels based on established criteria. Students who attempted a variety of reasoning strategies such as causal reasoning, using an analogy, abductive reasoning, data reconstruction and concept combination, revised their alternative conception to a scientific conception after the reasoning activity. On the other hand, some students could not revise their alternative conceptions because they only conducted an incomplete reasoning strategy. The study also found that they were unable to use other reasoning strategies, either.

본 연구에서는 식품에서의 L. monocytogenes에 대한 기 초자료를 제공하고자 2010년부터 2011년까지 서울지역에서 수거된 식품 총 1042건에서 L. monocytogenes를 분리 하여 항생제 감수성 검사를 하였다. 김밥 4건(0.8%), 육회 4건(2.6%), 연어제품 2건(11.1%), 돈육식품과 조리된 생선에서 각 1건씩(각5.9%, 6.3%) 총 12균주가 분리 동정되었다. 분리 균주를 20종의 항생제에 검사한 결과 대다수 항생제(16종)에 감수성을 나타내었지만 cefotetan (11균주), cefotaxime (7균주), cefepime (6균주)에서 내성을 나타냈으며 3균주에서 임상치료에 자주 사용되는 tetracycline에 대해서 내성을 나타내었다.

This study aims to compare the ease of men's slim pants patterns, and to analyze the fit and appearance through the 3D virtual garment system. The study selected four educational materials and one industrial pattern of slim pants for a total of five items. The CLO 3D Modelist program was utilized to carry out the appearance evaluation through virtual wearing and opacity, and a comparison was performed regarding the clothing pressure when the virtual model was standing and walking. The results of our comparison of the patternmaking for slim pants showed that pattern C pants had the greatest ease on the waist circumference, while B pants showed no ease. The C and E pants also had the most ease on the hip measurement. In the appearance evaluation, A pants received the most favorable results, followed by D, E, B, and C, in descending order. The clothing pressure appeared to be mainly red on the waist, crotch, and hem when standing in all pants, so the clothing pressure was high. While walking, the stress appeared to be different for the left and right parts of the body, and the most significant difference was observed on the thigh area.

Utterly in Their Collocation Patterns and Stand-Alone Use. The Sociolinguistic Journal of Korea 22(2), 91-110. This paper analyzes the maximizers absolutely and utterly in discourse, focusing especially on their collocation patterns and stand-alone use. I have elucidated the connection between their combinations in their dependent use and stand-alone use. This study connects the manners of stand-alone use of absolutely and utterly to their collocation patterns in dependent use. Absolutely strongly tends to collocate with positive lexical items, and frequently with an affirmative token, thus absolutely appears in stand-alone use, often as a response token, whereas utterly never occurs in independent use. The stand-alone form tends to be a better fit for interactive pragmatic roles, such as turn initiation, which is used to respond to a prior speaker, absolute acknowledgment, agreement, pre-closing signal, solidarity, and the floor-holding and bridging devices. The larger relevance of this study is to understand the impact of language use, and analyze these words' collocations and stand-alone use. (169)

The purpose of this study was to estimate usage of vitamin and mineral supplements as over-the-counter (VM-OTC) drugs as well as examine factors associated with VM-OTC usage in Korean adolescents. A total of 1,407 adolescents attending middle or high school in all parts of country were included in the analysis. Prevalence of VM-OTC usage was 56.1%, and it was higher as monthly income, father’s education level, and socioeconomic status of family increased (p<0.001). VMOTC intake was higher in middle school students than in high school students as well as in rural areas or small & mediumsized city residents than big city residents (p<0.01). Subjects mainly received information on VM-OTC mainly from ‘family and relatives’ (46.6%), whereas only 20.3% received information from experts. Subjects took VM-OTC ‘when they are healthy’ (49.1%), ‘when they feel sick’ (17.7%), ‘when they are on a diet’ (17.3%), and ‘when they are stressful’ (15.9%). The effectiveness of taking VM-OTC were mainly ‘fatigue recovery’ (35.0%), ‘health improvement’ (30.6%), and ‘nutritional status improvement’ (13.2%). The most frequently used VM-OTC was vitamin C (49.1%), multi-vitamins (18.6%), multi vitamins & minerals (13.2%), and calcium (9.2%). Among VM-OTC users, only 21.9% replied that they usually check the nutrition facts when they buy products, 62.4% follow the recommended dosage, and 9.7% fully understand the nutrition labels of the products. According to logistic regression analysis, the most influential factor affecting VM-OTC use was parents’ and siblings’ VM-OTC consumption (p<0.001). In addition, school type (middle or high school) (p<0.01), residence (p<0.05), self-concerns about health (p<0.05), father’s education level (p<0.05), and socioeconomic status of family (p<0.05) all influenced VM-OTC use. These results show that VM-OTC use is widespread among adolescents, few users actually check and fully understand the nutrition labels when they purchase VM-OTC, and they are highly dependent on unprofessional advice and information. Therefore, it is necessary to educate adolescents to help them select proper VM-OTC and read nutrition labels.

In 2005, Asia Pacific had the largest percentage of recreational shoppers in the world, while at the same time, Indonesia achieved the highest percentage for recreational shopping in Asia Pacific. (AC Nielsen, 2006). Shopping malls in Indonesia are growing rapidly and have currently increased in size, theme and location, and in the number of different types of shops. Given the rapid growth of malls, mall managers and retailers face the challenge to develop new strategies to survive in this highly competitive market. To gain greater insight into the relationship between shoppers and retailers, our aim is to explore shoppers’ behavior during their visit to the mall, specifically with respect to the type of shops visited. We will identify different shopping patterns and their characteristics based on 171 unobtrusive observations of shoppers using hierarchical clustering analysis. The results indicate that four shopping styles can be identified: fashion shoppers, basic shoppers, social shoppers, and entertainment seekers. Our results enhance an understanding of shopping styles. Mall managers and retailers could use this knowledge to decide the appropriate retail mix in the mall.

Although the majority of surviving pigs cloned by somatic cell nuclear transfer (SCNT) appear to be physiologically normal, there is a general lack of detailed hemato-physiologic studies for the period of early adulthood to substantiate this claim. In the present study, we investigated variation in blood chemistry and endocrinological parameters between mesenchymal stem cells (MSCs) derived from cloned and normal age-matched female and male miniature pigs. Cloned females and males showed normal ranges for complete blood count assessments. Biochemical assessments showed that γ-GGT, ALT and cholesterol levels of male and female clones were significantly (P<0.05 or P<0.01, respectively) higher than that of age-matched control miniature pigs. Variations in insulin and IGF-1 were higher in female clones than in male clones and controls. Thus, although female and male cloned miniature pigs may be physiologically similar to normal animals, or at least within normal ranges, a greater degree of physiological and endocrinological variation was found in cloned pigs. The above variation must be taken into account before considering cloned female or male miniature pigs for various biomedical applications.

In this study, nano-scale copper powders were reduction treated in a hydrogen atmosphere at the relativelyhigh temperature of 350℃ in order to eliminate surface oxide layers, which are the main obstacles for fabricating anano/ultrafine grained bulk parts from the nano-scale powders. The changes in composition and microstructure beforeand after the hydrogen reduction treatment were evaluated by analyzing X-ray diffraction (XRD) line profile patternsusing the convolutional multiple whole profile (CMWP) procedure. In order to confirm the result from the XRD lineprofile analysis, transmitted electron microscope observations were performed on the specimen of the hydrogen reduc-tion treated powders fabricated using a focused ion beam process. A quasi-statically compacted specimen from the nano-scale powders was produced and Vickers micro-hardness was measured to verify the potential of the powders as thebasis for a bulk nano/ultrafine grained material. Although the bonding between particles and the growth in size of theparticles occurred, crystallites retained their nano-scale size evaluated using the XRD results. The hardness results dem-onstrate the usefulness of the powders for a nano/ultrafine grained material, once a good consolidation of powders isachieved.

본 연구는 남한지역 백두대간 마루금 일대의 고도별 식물 다양성 분포 패턴 및 기후인자, 면적, 기하학적 억제인자, 순일차 생산량이 고도별 식물 다양성 분포 패턴에 미치는 효과를 구명하기 위해 수행되었다. 백두대간 마루금 일대를 따라 위치한 1,100개의 조사구에 대한 식생조사 결과, 총 97과 342속 802종의 식물종이 관찰되었으며, 고도에 따른 식물종의 α 다양성을 나타내는 종풍부도와 Shannon-Wiener 지수는 단봉형 패턴을 나타내는 반면, β 다양성을 나타내는 Jaccard와 Chao-Jaccard 유사도 지수는 고도에 따라 일반적으로 증가하는 경향을 나타내었다. 또한, 이러한 분포 패턴을 제어하는 인자로서 기하학적 억제인자가 α 다양성을 설명하는 가장 중요한 인자로 나타났으며, β 다양성은 기후인자가 가장 높은 설명력을 가지는 인자로 나타났다. 본 연구는 동일한 분류군 내에서도 다양성 측정방법에 따라 상이한 고도별 분포 패턴 및 제어인자를 가진다는 것을 제시하며, 백두대간 마루금 일대의 식물 다양성을 제어하는 인자가 단순히 하나가 아닌 몇 가지 인자의 복합작용에 의해 나타나는 현상임을 의미한다.
