This study investigated luring distributions by water layer of common squid which were targeted by angling fishing vessels equipped with LED and metal-halide lamps using a scientific echosounder with a 120 kHz frequency in order to develop energy-effective underwater fish aggregation devices. In the analysis, angles of a transducer were changed from 0° to 45° and were rotated every 10° horizontally. It was shown that common squid were densely distributed from the surface to 40 m and they were also distributed in directions of 10°∼+30°, -30°∼-60°, and -120°∼-130°with the head of vessel as the center. Comparative results of angles of transducer on acoustical densities of common squid distributing in 21~40 m water depth showed an average 101.8 m2/nm2 in vertical direction of 0°, 12.3 m2/nm2 in angle of 30°, and 42.4 m2/nm2 in angle of 45°, respectively. It implied that more considerations on acoustic scattering strength by incidence angle direction of the transducer and swimming oriental angle direction of common squid would be required.

A multi-step deposition process for the gap-filling of submicrometer trenches using dimethyldimethoxysilane (DMDMOS), (CH3)2Si(OCH3)2, and CxHyOz by plasma enhanced chemical vapor deposition (PECVD) is presented. The multistep process consisted of pre-treatment, deposition, and post-treatment in each deposition step. We obtained low-k films with superior gap-filling properties on the trench patterns without voids or delamination. The newly developed technique for the gapfilling of submicrometer features will have a great impact on inter metal dielectric (IMD) and shallow trench isolation (STI) processes for the next generation of microelectronic devices. Moreover, this bottom up gap-fill mode is expected to be universally for other chemical vapor deposition systems.

PURPOSES: This study evaluates the reliability of the patterns of changes in the road surface temperature during winter using a statistical technique. In addition, a flexible road segmentation method is developed based on the collected road surface temperature data. METHODS: To collect and analyze the data, a thermal mapping system that could be attached to a survey vehicle along with various other sensors was employed. We first selected the test route based on the date and the weather and topographical conditions, since these factors affect the patterns of changes in the road surface temperature. Each route was surveyed a total of 10 times on a round-trip basis at the same times (5 AM to 6 AM). A correlation analysis was performed to identify whether the weather conditions reported for the survey dates were consistent with the actual conditions. In addition, we developed a method for dividing the road into sections based on the consecutive changes in the road surface temperature for use in future applications. Specifically, in this method, the road surface temperature data collected using the thermal mapping system was compared continuously with the average values for the various road sections, and the road was divided into sections based on the temperature. RESULTS : The results showed that the comparison of the reported and actual weather conditions and the standard deviation in the observed road surface temperatures could produce a good indicator of the reliability of the patterns of the changes in the road surface temperature. CONCLUSIONS: This research shows how road surface temperature data can be evaluated using a statistical technique. It also confirms that roads should be segmented based on the changes in the temperature and not using a uniform segmentation method.

This paper broadly addresses the development of optimal marketing budget allocating among firms in the Russian market and applies methodologies produced by the contemporary marketing practices (CMP) project (New Zealand, the university of Auckland). From that project, it would seem that there are two separate paradigms that distinguish modern firms, namely a transactional approach and a relational approach. In a transactional type, the marketing campaign depends entirely upon closing the sale, based on a marketing miх or 4P conception. Relational marketing is based, rather, on a long term relationships with the customer, and it is generally typical of B2B markets where a limited number of companies try to develop customer’s loyalty due to the strong competition. Using marketing practices according to these two paradigms in Russia as an emerging market, however, reveals a difficulty in determining how to apply the CMP method to businesses: how is firm efficiency in these markets associated with one paradigm or the other? Is the situation in Russia typical for transition or emerging markets, or is it closer to that of advanced market economies, and which patterns in marketing practices do companies from different financial level prefer? Finally, how can firms use this approach to optimize marketing resources allocation? These questions were not resolved by the CMP project, yet they are critical for understanding the evolution of firms in transition countries such as Russia. The theoretical understanding in the literature shows a general cross-country relationship between marketing practices and firm efficiency. It is generally admitted that marketing creates value for a company, e.g. by analyzing customer database, selecting profitable clients segments, activities of the company, choosing an appropriate business model and strategic direction of the company. These are some of the most prominent reasons why marketing and company’s revenues are closely connected (Doyle, 2000; Rust et.al. 2004). The literature on marketing practices additionally identifies several regularities for developed and emerging markets: 1. Increased effectiveness can be achieved primarily by using database technology: switch marketing attention from markets to customers (individuals) and analyze clients flow. (Sheth and Sisodia, 2002; Rust and Chung, 2006) 2. Markets should be aimed not only at the customer acquisition but also at the customer retention. (Sheth and Sisodia, 2002) 3. Marketing is mostly characterized by delayed effect in time, implying companies should relate marketing activities with longer term effects (Dekimpe, Hanssens, 1995). 4. The consumer-company interrelation influence on the cumulative level of the marketing assets of the company. (Reinartz and Kumar, 2002)

우포늪의 목포습지에서 수심에 따른 수생식물의 분포 특성을 밝히기 위한 연구가 수행되었다. 274개 지점에서의 수심 및 식물종 분포 현황에 대한 표본조사가 이루어졌다. 선행연구에서 이루어진바 없었던 목포에 대한 상세한 수심 분포 지도가 만들어졌다. 평균 수심은 77㎝(±29㎝), 최대 수심은 157㎝로서 가장자리는 60㎝이내이며, 중심부가 120-130㎝ 정도의 오목한 그릇 형태를 이루고 있는 것으로 나타났다. 본 연구를 통해 침수식물 6종(검정말, 나사말, 나자스말, 말즘, 붕어마름, 실말)과 부엽식물 3종(가시연꽃, 자라풀, 마름)의 서식이 확인 되었다. 이들 수생식물들의 분포는 통계적으로 유의한 차이(χ2 = 982.2, df = 8, p< 0.01)를 보여 환경조건에 따라 식물종의 분포 양상이 다른 것으로 확인되었다. 마름이 244회 출현하여 가장 높은 빈도로 출현하는 것으로 나타났으며, 말즘과 함께 수심이 깊을수 록 피도가 높아지는 분포 양상을 보였다. 가시연꽃, 자라풀, 검정말, 나자스말, 붕어마름 5종은 수심이 깊을수록 피도가 낮아지는 음의 상관관계를 나타내었다. 수심에 따른 수생식물의 분포는 근본적으로 각각의 식물종이 가지는 생태적 특성에 의한 것이지만, 목포습지의 환경 특성을 반영하고 있는 것으로 나타났다.

To elucidate occurrence patterns of C4 plants in agroecosystems, we surveyed flora inside fields and embankments in 222 sites in farming lands in summer and fall, 2013. We also observed Kranz anatomy and analyzed carbon stable isotope to classify photosynthesis types. Our study observed total 54 species of C4 plants in 33 genera and 9 families of vascular plants besides cultivated crops occurring in farming fields. The most common species was Portulaca oleracea L. followed by Digitaria ciliaris and Echinochloa crusgalli (L.) P. Beauv. var. crusgalli among the C4 plants. The ratios of C3 and C4 species number to total number of species tended to maintain constant regardless of survey times and habitat types. The proportion of C4 species to the total number of species were more influenced by the number of C3 species than those of other types in the surveyed sites. Sizes of cultivation areas did not affect the proportions of C4 plants. Increasing number of simultaneous weeding methods, especially with cutting method, appeared to decrease the number of C3 plants. On the other hand, as the number of cultivated crops increased, both C3 and C4 plants increased but the proportions of C4 species remained. We interpret our results that proportion of C4 species in agroecosystems, appear to be dependent on the number of C3 species, which in turn, appear to be affected by cultivation methods.

본 연구에서는 Tg가 서로 다른 폴리에스테르 바인더로 실버 페이스트를 제조하여 점도 및 점탄성를 측정하였다. 그리고 제조된 실버 페이스트를 스크린인쇄법으로 전극을 인쇄하여 folding 및 stretching test에 따른 전도성 변화 및 전극패턴의 표면형상 변화에 대해서 연구하였다. 그 결과 folding test에서는 Tg가 낮고, 높고와는 관계없이 folding횟수의 증가에 따라서 저항치가 선형적으로 증가됨을 알 수 있었다. 그러나 stretching test결과에서는 Tg에 따른 명확한 특성차이가 나타났다. 즉 신율(elongation)이 증가함에 따라서 높은 Tg을 가진 바인더로 제조된 실버 페이스트의 경우에는 40%이상에는 저항치 측정이 불가능했지만 낮은 Tg로 제조된 것은 80%까지 저항치가 측정되었다. 결론적으로 80%라는 높은 신율을 요구하는 분야에는 낮은 Tg을 가진 바인더를 사용하는 것이 바람직함을 알 수 있었다.

Infrared thermography provides the colorful images of concerning area where local changes of surface temperature occurs and can be used to measure the fine temperature of human body. Unlike the radiography technique, it is determined by the presence or absence of existing anatomical principles capable of quantitative evaluation and visible to the physiological and functional state of the human body. In this paper, it was studied the characteristics of dynamic motion conditions in the hands due to physiological changes of temperature distribution. The results showed that the difference between the change in temperature characteristics for the left and right hand.

In the present study, the effects of non-thermal plasma, corona discharge plasma jet (CDPJ) against foodborne disease bacteria (Escherichia coli O157:H7 ATCC 43894, Salmonella typhimurium ATCC 13311, Staphylococcus aureus ATCC 25923) were determined, and the inactivation patterns were modeled using GinaFiT software in Microsoft Excel. Among inactivation models studied, Weibull-tail model was chosen as the best fit model based on SSE, RMSE, and r 2 values. The initial decimal reduction times (δ) of E. coli O157:H7, S. aureus, and Sal. typhimurium were 6.36, 8.31, and 12.11 s respectively. The inactivation effect increased with the current strength and was highest at span length of 25 mm. After 120 s treatment of the CDPJ at 1.50 A with span length of 25 mm, E. coli O157:H7 was reduced by 5.26 log, S. aureus by 4.21 log, Sal. typhimurium by 2.89 log.

The objective of this study was to determine the effect of bacterial inoculation (Lactobacillus plantarum or combo inoculant mixed with Lactobacillus plantarum and Lactobacillus buchneri) and addition of fibrolytic enzyme on chemical compositions and fermentation characteristics of whole crop barley (WCB) and triticale (TRT) silage, their ruminal in vitro fermentation, and digestibility. In TRT silage, enzyme addition significantly (p<0.01) decreased NDF content compared to no enzyme addition treatment. Organic acids such as lactate and acetate contents in WCB and TRT silages were significantly (p<0.01) higher compared to those in the control. Particularly, lactate content was the highest in L. plantarum treatment. Fibrolytic enzyme treatment on both silages had relatively higher lactic acid bacteria content, while mold content was lower in both treatments compared to that in the control. In vitro dry matter digestibility was generally improved in WCB silages. It was higher (p<0.01) in TRT with mixed treatment of L. plantarum, L. buchneri, and enzyme compared to others. In vitro ruminal acetate production was relatively higher in treatments with both enzyme and inoculant additions compared to that in the control. Therefore, the quality of silage and rumen fermentation could be improved by inoculants (L. plantarum and L. buchneri) regardless whether whole crop barley (WCB) or triticale (TRT) silage was used. Although it was found that fibrolytic enzyme addition to both silages had various quality and rumen fermentation values, further study is needed

Automated error detection and feedback systems are becoming an important component of online writing practice services for ESL/EFL (English as a second/foreign language) learners. The main purposes of the study are to: (a) collect samples of essays written by ESL learners with different native language (or L1) backgrounds that are error-coded by an early version of an automated error-detection system (CritiqueTM) and trained human coders; and (b) identify some unique patterns of writing errors for different first language (L1) groups. Data analyzed in this study included 18, 439 TOEFL◯R CBT essays error-coded by CritiqueTM and a much smaller, combined sample of 480 TOEFL◯R CBT/TOEFL iBT◯R essays error-coded by trained human coders. A comparison of error rates across five different language groups showed some unique patterns: (a) the Arabic and Spanish groups were the highest on both spelling and punctuation errors; (b) the Korean and Japanese groups had the highest article error frequency; and (c) the Chinese group had the highest number of errors related to verb conjugations or adjective and noun inflections. The implications of these findings are discussed in terms of understanding the nature of L1-related writing errors and enhancing the automated error detection and feedback systems.

2013~2014년 동안 전북지역 블루베리에서 총 37종의 해충이 조사되었다. 주요해충은 블루베리혹파리, 목화진딧물, 갈색날개매미충, 볼 록총채벌레, 미국흰불나방, 장수쐐기나방 6종이었다. 목화진딧물 피해는 5월 중순 익산과 진안에서 심하게 발생하였다. 총채벌레 피해는 모든 지 역에서 개화기인 6월초에 심하였고, 어린묘에서 심하였다. 갈색날개매미충은 중산간지역인 순창과 진안지역에서 대발생하여 전 지역으로 확산 되고 있었다. 미국흰불나방은 6월 익산에서 특이적으로 집중 발생하는 경향이었다. 쐐기나방은 5종이 발생하였는데 그 중 장수쐐기나방이 모든 지역에서 발생밀도가 가장 높았다. 블루베리혹파리 피해는 중산간지대인 순창과 진안지역보다 평야지대인 익산지역에서 심하였고, 3년생 이하 어린 묘에서 피해율 60~78%로 5년생 이상 피해율 30~50%에 비하여 높았다. 또한, 하우스에서 피해율은 50~80%로 노지 피해율 30~40% 보 다 높게 나타났다.

The effect of weir construction (2009~2011) was investigated on algal bloom dynamics and surrounding conditions in the Youngsan River by analyzing the long-term (2001~2014) data provided by the Water Information System, Ministry of Environment. The data include chlorophyll a and water properties such as total suspended solids (TSS), ammonium (NH4 +), nitrate (NO3-), orthophosphate (PO43-), total nitrogen (TN), total phosphorus (TP) and DIN/DIP molar ratio collected from 12 stations along the channel of the river. Temporal variations were examined using data collected monthly from 2001~2014 and Box-Whisker plot was used to examine the difference in algal bloom dynamics between before (2006~2008) and after (2012~2014) the weir construction. Pearson’s correlation analysis was also used to analyze the correlation of parameters. The results showed that TSS affecting water turbidity increased during the construction but decreased especially at the stations located in the upper and middle regions of the river after the construction. Ammonium concentrations increased whereas the concentrations of other nutrients decreased after the construction inducing an increase in N:P molar ratio. Chlorophyll a decreased suddenly during the construction but increased clearly after the construction at the stations where TSS decreased. This indicates that algal blooms can develop in the Youngsan River due to a decrease in turbidity that increases light penetration in water column although the concentrations of nutrients such as orthophosphate were reduced after the weir construction.

The purpose of this study was to examine the difference of middle school students’ game-oriented life according to their game usage patterns. The subjects of the study was 1,861 school students included in the panel data from the survey conducted by The National Youth Policy Institute. For data analysis, SPSS WIN 21 program was used to conduct one-way ANOVA. The result shows that the frequency of game play, the number of hours they play game on weekdays and weekends and the time span of game play were related to the game-oriented life. However, this tendency was not applied to those who don't play game at all. This suggests it could be more desirable to regulate students to play game for an appropriate amount of time rather than prevent them from playing games at all, when it comes to the matter of the potential problem according to playing games.

본 연구에서는 산림생태계 훼손 유형별 표토의 이화학적 특성 비교와 식재기반 조성 재료로서의 활용 여부를 평가하 였다. 표토는 산림생태계 훼손 유형별 훼손지역 12개 지역, 36개 지점과 각 훼손지 주변에 위치한 자연지역 12개 지역, 36개 지점, 총 72개 지점에서 채취하여 분석하였다. 분석 결과, 자연지역의 토성은 식양토~사양토, 용적밀도는 0.95~1.10 Mg/㎥, 고상률은 35.7~44.0 ㎥/㎥, 공극률은 56.0~64.3 ㎥/㎥, 내수성입단율은 8.4~35.8%, 토양경도는 5~13 ㎜, 토양산도는 5.3~6.1, 전기전도도는 0.14~0.65 dS/m, 전질소량은 0.28~0.42%, 양이온치환용량은 14~22 cmol+/㎏, 치환성칼륨함량은 0.15~0.31 cmol+/㎏, 치환성칼슘함량은 2.07~2.84 cmol+/㎏, 치환성마그네슘함량은 0.45~1.97 cmol+/㎏, 유효인산함량은 17~96 ㎎/㎏, 유기물함량은 3.2~5.6%의 범위를 나타냈으며, 훼손지역의 토성은 식양토~양질사토, 용적밀도는 1.54~1.75 Mg/㎥, 고상률은 52.8~58.0 ㎥/㎥, 공극률은 42.0~47.2 ㎥/㎥, 내수성입단율 은 4.2~22.5%, 토양경도는 13~25 ㎜, 토양산도는 4.8~5.5, 전기전도도는 0.13~0.62 dS/m, 전질소량은 0.02~0.12%, 양이온치환용량은 5~15 cmol+/㎏, 치환성칼륨함량은 0.11~0.18 cmol+/㎏, 치환성칼슘함량은 0.45~2.36 cmol+/㎏, 치 환성마그네슘함량은 0.39~0.96 cmol+/㎏, 유효인산함량은 15~257 ㎎/㎏, 유기물함량은 0.4~2.2%의 범위를 나타냈다. 자연지역과 훼손지역 표토의 이화학적 특성 비교를 통해 훼손지역 표토가 자연지역 표토에 비해 이화학적 특성이 악화되었음을 확인할 수 있었다. 이에 향후 표토 재활용을 위한 보전 및 관리 대책이 필요한 것으로 판단되었다.

1. 우리나라 쌀 소비량은 지속적으로 감소하고 있으나 쌀 가 공식품의 매출은 꾸준히 증가하는 추세에 있다. 2. 이에 본 연구는 농촌진흥청 농식품 소비자 패널조사 자 료(703가구)를 이용하여 최근 5년간 쌀 가공식품 구매패턴의 변화를 파악하고자 하였다. 이를 위하여 쌀 가공식품을 밥류, 죽류, 면류, 떡류, 방류, 과자류, 주류, 음료류, 조미류, 가루류 10종류로 분류하고, 쌀 가공식품의 종류별, 월별, 구매장소별 구매가구 수, 구매금액, 구매빈도 등 전반적인 구매패턴의 변 화를 살펴보았다. 3. 향후 소비 증가가 예상되는 쌀 가공식품의 종류와 향후 요구되는 관련 연구과제를 제안하였다.

이 연구는 1930년대 경성의 조선인과 일본인의 주거지와 공업활동을 분석한다. 1930년대는 한반도의 공업화가 집중적으로 진행되는 시기로 경성은 당시 공업화의 핵심공간이었다. 이 연구는 경성공업의 공간적 분포를 조선인과 일본인의 두 민족으로 구분하여 분석한다. 특히 기존의 근대 한국의 인문·사회적 공간현상에 대한 연구가 정성적 접근에 제한된 바, 이 연구에서는 근대 데이터를 정량화하여 공간통계적 분석법을 적용하였다. 연구 결과 경성은 민족에 따른 주거지 분화가 명확하게 나타났으며, 이러한 주거지 분화는 주요 민족 별 공업 분포에도 반영되었다. 하지만 공업의 공간적 분포는 민족 별 주거지 분화 뿐만 아니라 지가 등 다른 많은 요소들의 영향을 받았음을 알 수 있다. 이 연구는 근대 역사 자료에 대한 정량적인 분석을 시도한 것으로 학문적인 의미가 있다.

온실재배 오이에 발생하는 목화진딧물의 발생밀도를 추정하는 표본조사법을 개발하기 위하여 2개년(2013-2014년) 동안 주 전체의 잎별 발생밀도를 조사하였다. 목화진딧물의 공간분포 특성은 일반적으로 사용되는 Taylor’s power law(TPL)와 Iwao’s patchiness regression (IPR) 두 가지 방법을 이용하여 분포특성을 조사하였다. 목화진딧물의 주 전체 밀도를 대표할 수 있는 표본단위를 일정 잎 위치의 평균밀도와 주 전체의 잎당 평균밀도와의 일반선형 회귀식을 이용하여 결정하였다. 적정 표본단위는 오이 생육기에 따라 달랐는데, 총엽수가 9매 미만일 경우 2매(중위 엽과 최하위+1번째 엽), 그 이상인 경우에는 3매(위로부터 4번째, 7번째, 최하위+1번째 엽)를 조사하는 것이 적합하였다. 오이에서 목화진딧물의 공간분포 특성은 TPL과 IPR의 기울기가 모두 “1”보다 커 집중분포를 하고 있었으며, 진딧물의 평균-분산 관계를 TPL이 IPR보다 더 잘 설명하 였다. TPL의 기울기와 절편은 연차간에 차이가 없었으며, Green과 Kuno의 식을 이용하여 고정 정확도(D) 수준에서의 축차표본조사법을 개발 하였다. 목화진딧물의 축차표본조사법은 Green의 방법이 Kuno에 비해 더 효율적이었다. 목화진딧물의 일정 평균밀도를 추정하기 위해 필요한 조사 주수는 D값과 잎당 평균밀도가 낮을수록 증가하는 경향이었다. 표본조사를 중지할 수 있는 누적 진딧물 수는 D값이 낮을수록, 조사 주수가 적을수록 증가하는 경향이었다. 목화진딧물 잎당 10마리의 밀도를 추정하기 위해 필요한 조사 주수는 13주이었으며, 이 때 조사를 중지하기 위한 누적 진딧물수는 131마리이었다.
