The purpose of this study was to determine the optimal mixing ratio of olive oil, parmesan cheese, and nuts for preparation of pesto with spinach. Based on a surface response methodology (RSM), the independent variables were olive oil (100~300 g), parmesan cheese (25~75 g) and nuts (12~36 g). The dependent variables were physico-chemical properties as pH, color values (L, a, and b values), viscosity and sensory evaluation. pH decreased with increasing parmesan cheese levels. The L value decreased and the a and b values increased with increasing olive oil levels. Viscosity was negatively correlated with olive oil levels but positively correlated with the amounts of parmesan cheese and nuts. The addition of oil exerted a positive effect on gloss, and oily taste. In the sensory evaluation, the values of appearance, color, flavor, taste and overall acceptance were in the range of 4.4~7.2, 3.7~7.4, 4.4~7.1, 3.9~7.3 and 3.5~7.6, respectively. The sensory evaluation results showed significant values in appearance (p<0.01), flavor (p<0.01), taste (p<0.01) and overall acceptance (p<0.05). The optimal amounts of spinach pesto with olive oil, parmesan cheese, and nuts were determined by numerical optimization of a canonical model and graphical optimization. The optimal amounts were 175.29 g of olive oil, 49.51 g parmesan cheese, and 27.37 g of nuts per 100 g of spinach.

연산 오계육은 오래전부터 건강기능 증진 및 치료 효능이 높은 것으로 알려져 왔다. 최근 천 연물 단백질 유래 기능성 펩타이드 효능이 알려짐에 따라, 본 연구는 연산오계 부산물인 내장육 단백질 로부터 고압처리기술과 프로티아제를 이용하여 펩타이드 생산 최적공정과 생성물의 특성을 연구하였다. 내장육의 가수분해는 효소 bromelain 과 내장육을 고압 반응기에 투입을 하여 실시하였다. 최적 공정 조건 확립을 위하여 고압처리기의 압력(30 - 100 MPa), 효소반응 시간 (1 - 5시간), 내장육의 양(10 – 30%)의 범위에서 수행되었다. 효소 반응 후 각 조건에 따른 내장육 단백질의 가수분해도, 생산 펩타이 드들의 아미노산 및 분자량 분포를 분석하였다. 연구 결과 내장육 단백질 가수분해 최적조건으로 압력 90 MPa, 효소반응시간 3–4시간, 내장육의 함량 20%에서 결정 되었다. 최적조건에서 오계 내장육 단백 질의 65% 이상이 가수분해 되었다. 대부분의 가수분해물의 분자량들은 400–1,000 Da 이하의 분포를 보여주어 대부분이 펩타이드로 판단되었다. 생산 펩타이드들은 비극성 소수성 아미노산들 42.3%, 극성 비전하 아미노산들 26.0%, 양 전하 아미노산들 13.3%, 음 전하 아미노산들 18.6% 로 분포되었다. 따라 서 항산화 능력이 뛰어난 비극성 아미노산의 분포를 보아 건강 기능 식품 소재로서 활용할 가치가 높을 것으로 기대를 한다.

For evaluating the boar semen quality, sperm motility is an important parameter because the movement of sperm indicates active metabolism, membrane integrity and fertilizing capacity. Phospholipase C zeta (PLCz) is important enzyme in spermatogenesis, but the effect has not been confirmed in pigs yet. Therefore, this study was aimed to analyze their association with sperm motility and kinematic characteristics. DNA samples from 124 Duroc pigs with records of sperm motility and kinematic characteristics [total motile spermatozoa (MOT), curvilinear velocity (VCL), straight-line velocity (VSL), the ratio between VSL and VCL (LIN), amplitude of lateral head displacement (ALH)] were subjected. A SNP in non-coding region of PLCz g.158 A > C was associated with MOT (p < 0.05), VCL (p < 0.01), LIN (p < 0.01) and ALH (p < 0.05) in Duroc population. Therefore, we suggest that the intron region of the porcine PLCz gene may be used as a molecular marker for Duroc boar semen quality, although its functional effect was not defined yet. Whether the association is due to the candidate gene or not require further verification. Thus, it will be of interest to continue association studies in the regions surrounding those genes.

For evaluating the boar semen quality, sperm motility (MOT) is an important parameter because the movement of spermatozoa indicates active metabolism, membrane integrity and fertilizing capacity. Estrogen receptors 2(ESR2) is involved in estrogen related apoptosis in cell cycle spermatogenesis, but their functions have not been confirmed in pig until now. Therefore, this study was conducted to analyze their association with sperm motility and kinematic characteristics. DNA samples from 105 Duroc pigs with records of semen motility and kinematic characteristics [Total motile spermatozoa (MOT), Curvilinear velocity(VCL), Straight-line velocity(VSL), the ratio between VSL and VCL(LIN), Amplitude of Lateral Head displacement(ALH)] were analyzed. A SNP in coding region of ESR2 g.35547A > G in exon 5 was associated with MOT (p < 0.05) in Duroc population. Therefore, we suggest that the porcine ESR2 gene may be used as a molecular marker for Duroc boar semen quality, although its functional effects were not defined yet. These results might shed new light on the roles of ESR2 in spermatogenesis as candidate gene for boar fertility, but still the lack of association across populations should be considered.

Cluster-of-differentiation antigen 9 (CD9) gene expressed in the male germ line stem cells is crucial for sperm–egg fusion, and was therefore selected as a candidate gene to investigate Duroc boar semen motility and kinematic characteristics. This study was performed to investigatetheir association with semen motility and kinematic characteristics. DNA samples from 96 Duroc pigs with records of sperm motility and kinematic characteristics [Total motile spermatozoa (MOT, 82.27±5.58), Curvilinear velocity(VCL, 68.37±14.58), Straight-line velocity(VSL, 29.06±6.58), the ratio between VSL and VCL(LIN, 47.36±8.42), Amplitude of Lateral Head displacement(ALH, 2.88±0.70)] were used in present study. A single nucleotide polymorphism (g.358A>T) in intron 6 was associated with MOT, VCL, VAP and ALH in Duroc population (p<0.05). Therefore, we suggest that the porcine CD9 may be used as a molecular marker for Duroc boar semen quality, although its functional effect was not clear yet. These results will improve the understanding of the functions of the CD9 in spermatogenesis within the reproductive tracts, and will shed light on CD9 as a candidate gene in the selection of good sperm quality boars.

The Korean native cattle, Hanwoo, is the most popular breed of beef cattle in Korea. However, the reproductive performance data are limited although reproduction is one of the most economically and biologically important in beef production. Therefore, this study was undertaken to investigate reproductive performance parameters including calving interval, parity for life time production. Data collected from 206,827 calvings were analyzed. There were no significant differences in calving interval and gestation days as parity increased from 2nd and 13rd parity cow, from spring to winter. However, we found a dramatic increase in calving interval after year 2000. About 1 month were increased per year ( y = 30.578x + 344.45 R² = 0.9157). Interestingly, we observed that parities for life time can be affected by birth weight. Calves with 23 kg at birth showed highest parities, 3.4±2.0 times. In summary, this study provides valuable data on reproductive performance of Hanwoo and the data presented here can be used as a standard target for optimising and enhancing reproductive performance.

지구 기후변화에 따라 아열대성 해충이 온대지역으로 이주를 통해 서식지를 넓히고 있다. 아열대성 해충인 콩명나방(Maruca vitrata)이 국 내에서 팥을 비롯한 콩과작물에 경제적 피해를 일으키고 있다. 비교적 유전적 변이가 큰 곤충으로 알려진 콩명나방에 대해서 국내 집단의 기원에 대해서 의문을 갖게 되었다. 국내 콩명나방 집단의 유전적 특성을 이해하기 위해 cytochrome oxidase subunit 1 (cox 1) 유전자의 염기서열을 판독 하였고, 이를 다른 지역 집단들과 분자계통학적으로 분석하였다. 전 세계에 분포하고 있는 콩명나방은 크게 3 그룹(아시아-아프리카, 아메리카, 오세아니아)으로 분류되었다. 이 가운데 국내 콩명나방은 아시아-아프리카 그룹에 속했다. 국내 집단의 살충제 감수성을 분석하기 위해 작용기작이 서로 다른 7 가지(4 종류의 신경독 약제, 1 종류의 곤충성장조절제, 2 종류의 생물농약)의 약제로 평가하였다. 콩명나방의 어린 유충은 분석된 모든 약제에 비교적 감수성이 높았다. 그러나 노숙 유충의 경우는 어린 유충에 비해 감수성이 현저하게 저하되었다. 처리 후 7 일간 분석된 살충력 조사에서 조사된 어느 약제도 콩명나방의 최종령 유충을 효과적(> 50% 방제가)으로 방제하지 못하였다.

무당벌레(Harmonia axyridis)는 종내에서 초시색상패턴이 매우 다양하게 존재한다. 본 논문에서는 서로 다른 색상패턴의 무당벌레를 대상 으로 amplified fragment length polymorphism (AFLP)을 실시하여 무당벌레의 초시색상 패턴간 유전형질의 차이를 확인하고자 하였다. 총 28 개의 프라이머 조합으로 실험을 실시한 결과, 총 2,741 개의 밴드가 검출되었다. 그 중 20 개의 밴드(S1-S20)만이 특정 색상패턴에서 나타났다. 이들 가운데 9 개의 밴드를 색상에 연관된 AFLP 후보 지표로 선발하였다. 밴드 가운데 S1과 S2, S20은 Succinea 1, 2 변이형에 공통적으로 나타났으며, S3와 S5는 Conspicua 변이형에 특이적이었다. 또한 S13는 Spectabilis 변이형에, S15와 S18, S19는 Succinea 2 변이형에 특이적이었다. 특정 색상패턴에만 나타나는 9 개의 AFLP 지표들은 cloning을 통해 염기서열 분석을 실시하였고, GenBank를 이용해 다른 염기 서열과 비교를 해보았지만 아무런 상동성도 찾을 수가 없었다. 무당벌레 종 내 유전적 다양성을 평가한 결과, Spectabilis가 Conspicua보다 Succinea 변이형에 높은 유사성을 보였다. 색상에 연관된 AFLP 후보 지표를 기준으로 sequence characterized amplified region (SCAR) 지표로 변환하여 9 개의 AFLP 분자지표들 가운데에서 5 개만이 SCAR 지표로 전환될 수 있었으며, 이를 통해 AFLP 지표가 무당벌레의 색상과 연관되어 있는지 확인할 수 있었다.

It was a case study to use as a basic data for efficient the preservation and management of subalpine coniferous forest in national parks. It is based on inhabitation condition of 210 individuals of Abies koreana Wilson that was found through local investigation in the sub-alpine zone of Jirisan National Park and Songnisan National Park. It analyzed the effect of the geographical location and topographical features, which are the basics of location environment, on the growth of A. koreana. The variables related to the growth of A. koreana are tree height and diameter at breast height. Topographical features include geographical longitude, altitude above sea level, slope of the mountains, aspect that describes the direction in which a slope faces and topographical wetness index. Topographical features were extracted through GIS spatial analysis. It used canonical correlation analysis to estimate whether the two variables groups have related to each other and how much they are related, if any, and estimated the effect of the geographical and topographical features on the growth structure of A. koreana using multiple regression analysis. The tree height and diameter at breast height that represent the growth structure of A. koreana show greater relation to geographical latitude distribution than topographical feature and the geographical and topographical factors show greater relation to diameter at breast height than tree height. The growth structure’s variable and geographical and topographical variable of A. koreana have meaningful relation and the result shows that geographical and topographical variables explain 18.1% of the growth structure. The variables that affect the diameter at breast height of A. koreana are geographical latitude, topographical wetness index, aspect and altitude, which are put in order of statistical significance. The higher the latitude is, the smaller the diameter at breast height. Depending on the topographical feature, it becomes bigger. The variable that affects the tree height is topographical wetness index, which was the only meaningful variable. Overall, the tree height and diameter at breast height that are related to the growth structure of A. koreana are affected by geographical and topographical feature. It showed that the geographical feature affected it the most. Especially the effect of water among the topographical features is expected to be bigger than the other topographical factors. Based on the result, it is expected that geographical and topographical feature is an important factor for the growth structure of A. koreana. Even though it considered only the geographical and topographical features and used spatial analysis data produced by GIS, the research results will be useful for investigating and researching the growth environment of coniferous forest inhabiting in sub-alpine zone of national parks and are expected to be used as basic data for establishing measures to efficiently manage and preserve evergreen needleaf tree such as A. koreana.

Clematis patens는 미나리아재비과 으아리속에 속하는 다년 생 숙근초로 꽃잎화한 꽃받침을 가지고 있는 점이 특징이며 흰색, 분홍색, 자주색, 보라색, 등 다양한 화색이 존재한다. 본 연구에서는 C. patens ‘The President’에서 flavonoid 생합성 경로에 관여하는 유전자 중 delphinidin 계열 anthocyanin 색 소 합성을 유도하는 F3'5'H(ClF3'5'H)를 분리 동정하였으며, 화색 및 발달 단계별 ClF3'5'H 유전자의 발현 패턴을 분석하 였다. 또한 클레마티스 화색별 anthocyanin의 함량을 알아보 았다. 그 결과, 기존 보고된 Aconitum carmichaelii의 F3'5'H 유전자의 아미노산 서열과 79% 일치하여 높은 상동성을 갖는 것을 확인하였으며, ClF3'5'H 유전자의 발현 패턴은 흰색을 띠 는 클레마티스에서는 ClF3'5'H 유전자의 발현량이 많지는 않 았으나 다른 발달 단계에 비해 완전 개화한 단계에서 발현이 강했다. 분홍색을 띠는 클레마티스에서는 모든 발달 단계에서 ClF3'5'H 유전자의 발현이 검출되지 않았으며, 자주색과 보라 색을 띠는 클레마티스에서는 개화 직전 및 완전 개화 단계에 서 발현하였다. 이 결과로부터 클레마티스의 다양한 화색과 클 레마티스의 F3'5'H 유전자 발현과의 상관관계가 시사되었다.

This study was an attempt to analyze the basic analytical characteristics of octanal and nonanal compounds by TD and GC/FID system. The basic analysis (linearity, precision, MDL: method detection limit) showed similar results for VOCs in terms of QA/QC results with the same analysis system. Also, the results are sufficiently satisfy the QA/QC of the Korean odor analysis standard method. When using a polyester aluminum bag, the amount of loss was found to be about -2% to 7%. Adjusting the relative humidity and loss trend with the passage of time, the loss amount is found to be only a trace amount. With the exception of the styrene compound, all volatile organic compounds have a tendency to decrease slightly. Similar results were shown from Octanal and Nonanal. As a result, Octanal and Nonanal compound’s adsorption amount by the polyester aluminum bag was a quite small. The relative humidity and other compounds appear to be significantly unaffected by Octanal and Nonanal.

This study examined the reading passages of the National Assessment of Educational Achievement (NAEA) and middle school English textbooks in terms of their readability and lexical difficulty. The readability was measured by using Flesch-Kincaid Grade Level Index, while their lexical difficulty was measured in terms of STTR (standardized type-token ratio), frequency of tokens per type, and vocabulary frequency levels by using VocabProfile and Oxford WordSmith Tools 7.0. The results showed that there was a gap between the readability of the English textbooks and that of the NAEA conducted from 2012 to 2014, while the readability between the English textbooks and that of the 2015 NAEA reached a comparable level. However, the textbooks from one publisher showed substantively lower readability than those from the other publishers and the NAEA. Secondly, regarding vocabulary frequency levels, the words in 1K and 2K accounted for more than 90% of the textbooks and the NAEA, while the NAEA had a higher STTR and lower frequency of tokens per type than the textbooks. It suggests that the NAEA employed more various words with less repetition than the textbooks. Pedagogical implications are discussed.

이 연구는 TV 드라마 <시그널>의 주요 모티브인 과거, 현재, 미래가 상호작용하는 서사적 시 간 구성이 극적 긴장을 조성하는 데 어떤 역할을 했는지를 분석한다. 분석을 위한 이론적, 방법 론적 도구로 페터 퓌츠(Peter Pütz, 1977)가 제시한 서사물에서의 극적 긴장 조성 기법들을 활 용한다. 그리고 서사적 시간성에 대한 오랜 이론적 토대를 제공해온 쥬네트와 채트먼의 논의를 퓌츠와 비교한다. 이 글의 목적은 TV 드라마 <시그널>의 서사형식을 밝히는 것이다. 특히 서사 적 시간성을 뒤흔들어서 극적 긴장감을 불러일으키는 서사적 변형을 살펴보는 것이다. 이는 <시 그널>의 시간성과 시간을 통한 극적 긴장의 조성 기법이 <시그널>의 극적 완성도를 높이기 위해 서 어떻게 활용됐는가를 분석하는 것이다. 이를 통해서 서사적 시간성 문제에 대한 이론적 지평 을 확장하는 것이 이 연구의 궁극적 목표라고 할 수 있다. 페터 퓌츠가 제시한 극적 긴장을 조성 하는 기법들인 서사적 시간 구성의 다양한 요소들이 <시그널>의 전편에서 복합적으로 활용되고 있었다. ‘연속’과 ‘선취’, ‘역전’이라는 긴장 조성의 기법들은 <시그널>의 과거와 현재 혹은 현재 와 미래라는 이중적 서사 속에 자연스럽게 녹아들고 있었다. 이러한 극적 긴장 조성의 기법들은 <시그널>의 모티브인 무전기를 통해서 과거와 현재가 만난다는 서사적 설정에 매우 적합한 재현 도구로 쓰였다. <시그널>은 극적 긴장을 조성하는 기법들을 통해서 서사와 시간을 복합적이면서 도 체계적으로 구조화하는 데 성공했다. 즉 <시그널>의 대중적 성공과 높은 작품성은 서사적 시 간의 구조화와 그에 따른 극적 긴장의 성공적 조성에서 기인한다고 하겠다. 아울러 주요 캐릭터 역시 그러한 시간적 구조화에서 극적 긴장 조성의 기법적 역할을 수행했다. 이는 캐릭터 연구에 있어서도 중요한 관심의 대상이 될 수 있을 것으로 보인다. 끝으로 최근 늘고 있는 독특한 시간 성 혹은 멀티타임의 시간성을 모티브로 하여 제작되는 영화나 TV 드라마에 대한 연구와 분석에 있어서 극적 긴장을 조성하기 위한 방법을 제안한 퓌츠의 논의는 더욱 더 유용할 것으로 판단된 다.

Although chemical fertilizers have a quick effect and broad applicability to agricultural fields, they have caused many problems like increasing soil acidity or decreasing soil organic matters. Environmental-friendly agriculture has been attempted in various ways such as organic agriculture, natural farming, low input and sustainable agriculture. The common interest of all environmental-friendly systems is to decrease burden to agricultural environment by low input of agricultural labor and materials. This study was conducted to estimate overwintering capacity and genetic distance among Chinese Milk Vetch (Astragalus sinicus, CMV) collections based on morphological characteristics and AFLP (Amplified fragment length polymorphism) analysis. Furthermore, the effect of CMV as green manure was observed in mix-cultured paddy fields with rice, sesame and sweet-potato. An another objective of this study was also to compare the pattern of weed occurrence in paddy fields with or without CMV and different rice transplanting times. The CMV collected from Paju district in central region of Korea was successively occurring through self-reseeding without artificial management. However, there was no noticeable difference in growth habit between Paju native CMV and introduced CMV from China which is currently used in farm fields. On the basis of multi-dimensional scaling and tree analyses, there are no significant difference of agricultural growth characteristics among Paju and chinese collections only excepting leaf angle and root length. The flowering time of Gurye collection was fast for 1 week as compared to other collections. AFLP that was commonly used for plant classfication, was applied to exam the genetic variation of CMV collections. Total 579 PCR products and 336 polymorphic fragments were generated using 8 primer pairs.

미국에서 동성애 및 동성혼과 관련된 논쟁은 오래전부터 시작되었다. 미국의 일부 주법은 동성애행위자체를 법으로 금지하는 경우도 있었기 때문에, 동성애자들의 권리투쟁은 그에서부터 시작되었다. 그리고 그들은 동성혼 역시 이성혼과 법적으로 동등하게 취급되어야 하며, 동성혼을 법 적으로 인정받기 위한 권리투쟁을 계속해왔다. 그리고 2015년, 마침내 미국의 연방대법원은 5대 4로 동성혼 역시 수정헌법 제14조의 적법절차 조항과 평등보호조항에 의하여 보호되어야 함을 선언함으로써, 미국 전 역에서 동성혼을 합법화하였다. 한국은 아직 미국처럼 동성애 및 동성혼을 둘러싼 논란이 가열되지는 않은 단계이다. 그러나 지난 2013년, 광화문에서 한 동성커플의 공개적인 결혼식 및 혼인신고 이후로 이에 대한 주목은 예전보다 높아져가고 있다. 한국에서 동성애 및 동성혼을 둘러싼 사회적 논의는 아직도 미미하지만, 성적소수자로 분류되는 이들의 권리 또한 보호받아야 하기에 과연 그 범 위를 어디까지 인정할 것인지에 대한 법적 논의는 분명 필요하다. 이 논문은 미국에서의 동성애 및 동성혼 관련 판결분석에 주된 초점을 맞추었다. 연방대법원의 판결문 내용을 검토하여 판결의 점진적인 변화 를 살펴보고, 또한 그러한 변화를 이끌어 낸 원인은 무엇인지, 이전 판례 와의 차이는 무엇인지 등을 분석해본다. 그리고 이를 통해 한국에서 동 성혼을 제도화하는 데 있어 고려가 되어야 할 헌법조항들은 어떤 것이 있으며, 어떤 단계들이 필요한지 간략하게 논한다. 미국의 연방대법원 판 결분석은 그 자체로 우리에게 충분한 시사점을 제공해줄 것이

This study proposes a methodology to analyse social networks among participating design engineers during product development projects. The proposed methodology enables product development managers or the participating design engineers to make a proper decision on product development considering the performance of participating design engineers. It considers a product development environment where an integrated product data management (PDM) system manages the product development data and associated product development processes consistently in its database, and all the design engineers share the product development data in the PDM database for their activities in the product development project. It provides a novel approach to build social networks among design engineers from an operational product development data in the PDM database without surveys or monitoring participating engineers. It automatically generates social networks among the design engineers from the product data and relationships specified by the participants during the design activities. It allows analysts to gather operational data for their analysis without additional efforts for understanding complex and unstructured product development processes. This study also provides a set of measures to evaluate the social networks. It will show the role and efficiency of each design engineers in the social network. To show the feasibility of the approach, it suggests an architecture of social network analysis (SNA) system and implemented it with a research-purpose PDM system and R, a statistical software system. A product configuration management process with synthetical example data is applied to the SNA system and it shows that the approach enables analysts to evaluate current position of design engineers in their social networks.
