이 연구는 중국 태권도 지도자의 지도철학에 바탕이 될 수 있는 지도자, 지도방법등의 사항들을 지도자와 학부모를 대상으로 탐색하여 도장활성화 방안을 고찰하였으며, 연구의 방법은 문헌탐구와 함께 반구조화된 면접법을 이용한 질적 연구방법을 활용하였다. 첫째, 중국 태권도장은 시대적 흐름에 따른 급성장의 경제발전과 맞물려 태권도장이 순수 교육의 장으로 인식되어지기 보다는 경제적·상업적인 장소로 표출되고 있다. 따라서 중국지도자들은 소탐대실(小貪大失)을 해서는 안 되며 교육의 질을 높임과 동시에 지도자들의 자질에서도 제고의 노력이 요구된다. 둘째, 지도자들의 지도내용과 지도방법에서는 실전에서 필요로 하는 겨루기 기술에 많은 부분을 차지하고 있으나 수련 시 가장 중요하게 여기는 부분은 예의라고 밝히고 있다. 셋째, 중국은 문화적 특성에 따라 홍보방법과 수련관리 프로그램. 학부모들과의 소통 또한 수련생과 학부모 관리에 대한 방안이 시급한 문제로 대두되고 있다. 이러한 문제들은 수련생의 결석, 휴관, 복관에 대한 방법론적인 접근에서도 반드시 필요한 부분이므로 지도자, 프로그램, 수련시설과 같은 중요내용을 체계적이고 현실적인 내용으로 보완하여 태권도장의 이미지 제고에 노력을 기울여야 할 것이다. 넷째, 현재 중국지도자는 수련생들의 입관을 유도할 수 있는 내용이 부족하기에 인터넷 광고, 전단지, 태권도 시범, 구전광고, 블로그 마케팅 등 보다 많은 영역으로 확대되어 접근하여야 할 것이다. 다섯째, 중국 수련생의 학부모들은 태권도 수련에 있어서 기술적인 부분보다는 자녀의 사랑과 관심에 대하여 더욱 친밀함을 나타내고 있기에, 태권도 지도자의 품성과 인격을 더욱 높여야 할 것이다. 중국태권도의 활성화는 지도자, 지도방법과 내용, 수련프로그램에 대한 개발, 그리고 경영에 대한 새로운 패러다임의 구축이 절실히 요구된다. 따라서 중국 지도자에게 있어서 가장 필요한 요소는 실증적 경험에서 나오는 지도능력과 이것을 정립시키고 지도에 응용할 수 있는 전문적 지식, 그리고 올바른 가치관이 정립될 때 중국 지도자들의 지도철학의 발전과 태권도장의 활성화가 지속적이고 빠른 속도로 이루어 질 것이다. Objective of the present study is to provide measures for activating studios through exploring pointers that may constitute a foundation for leadership philosophy of Taekwondo leaders in China with leaders and parents. For study method, qualitative research methods using semi-structured interviews along with literature survey were utilized. First, Chinese Taekwondo studios are represented as an economic and commercial place in conjunction with rapidly growing economic development according to a historic flow rather than as a place for pure education. Consequently, Chinese leaders should not incur a great loss by pursuing a small profit, requiring an effort for enhancement of leaders` qualifications as well as the quality of education. Secondly, while leaders` guidance contents and methods mostly account for competing techniques required in actual fights, the part considered most important in training is pointed out to be an etiquette. Thirdlymeasures for publicity methods, training management programs, communications with parents along with trainees and parents management are considered to be urgent issues according to cultural characteristics of China. Since such matters are certainly essential in methodological approaches for trainees absenteeism, studio closure and reopening, an effort should be made for image enhancement of Taekwondo studios by supplementing important contents such as leaders, programs and training facilities. Fourth, since Chinese leaders lack in contents for inducing joining by trainees, the approach should be divided into many areas such as internet advertisements, fliers, Taekwondo demonstrations, orally transmitted advertisements, blog marketing, etc. Fifthly, parents of Chinese trainees display a greater intimacy with their children`s love and interset rather than technical parts in Taekwondo training,valuing leaders` character and personality very highly. For activation of Taekwondo in China, development of leaders, guidance methods and contents, training programs together with construction of a new paradigm for management are badly needed. Thus, activation of leasdership philosophy for Chinese Taekwondo leaders as well as Taekwondo studios may be achieved when they become leaders equipped with a leadership ability produced by positive experience as the most needed element, professional knowledge that can establish and apply it to guidance and correct values.

This study aimed to assess the disease incidence and distribution of toxigenic in Korean triticale. The patho- gen of triticale that cause Fusarium head blight were isolated from five different triticale cultivars that culti- vated in Suwon Korea at 2021 year. The 72 candidate were classified as a Fusarium asiaticum by morphology analysis and by ITS1, TEF-1α gene sequence analysis. And the results of pathogenicity with 72 isolates on seed- ling triticale, 71 isolates were showed disease symptom. Also, seven out of 71 Fusarium isolates were inoculat- ed on the wheat, to test the pathogenicity on the different host. The results showed more low pathogenicity on the wheat than triticale. The results of analysis of toxin type with 72 isolates, 64.6% isolates were produced nivalenol type toxin and other 4.6% and 30.8% isolates were produce 3-acetyldeoxynivalenol and 15-acetyl- deoxynivalenol, respectively. To select fungicide for control, the 72 Fusarium isolates were cultivated on the media that containing four kinds fungicide. The captan, hexaconazole, and difenoconazole·propiconazole treated Fusarium isolates were not showed resistance response against each fungicide. However, six isolates out of 72 isolates, showed resistance response to fludioxonil. This study is first report that F. asiaticum causes Fusarium head blight disease of triticale in Korea.

선택적 전류공급구조를 갖는 병렬형 A/D 변환기

본 논문에서는 full-flash A/D 변환기에서 전력소모를 줄이는 방법과 그의 회로를 제안하였다. Full-flash A/D 변환기에서 해상도가 증가하면 전압비교기의 수는 지수함수적으로 증가하며 모든 전압비교기가 항상 동작하여 전력 소모가 많으므로 제안하는 구조에서는 입력 신호의 크기에 까라 그 영역에 해당하는 위치에 있는 전압비교기를 선택적으로 켜줌으로써 전력 소모를 줄인다. 입력 신호의 크기를 판별하기 위하여 입력 신호의 범위를 찾는 회로를 설계하였다. 클리치 잡음을 줄일 수 있는 클럭 발생회로를 설계하여 사용함으로써 전압 비교기의 전류원에서 발생하는 잡음을 일반적인 클럭을 사용했을 때와 비교하여 1/4로 줄였다. 설계한 A/D 변환기는 out-off 주파수가 5GHz 인 1.2 m의 BiCMOS 공정으로 제작하였다. 이는 350Msamples /s의 변환 속도를 가지며 소모 전력은 900mW이다. A power-reduction technique for full-flash A/D converters is proposed. As the resolution of a full-flash A/D converter increases linearly, the number of comparators increases exponentially. The power dissipation is generally larger than other A/D converter architectures because there are many comparators, and they are operating continuously. In this proposed architecture, only a selected number of conmarators are made to operate instead of activating all the comparators of the full-flash A/D convertor. To determine whichcomparators should be activated, voltage levelfider circuits are used. A new clock driver is developed to suppress the dynamic glitch noise which is fed back into the input stage of the comparator. By using this clock driver, the glitch noise in the current source is reduced to one fourth of that when the typical clock signal is applied. The proposed architecture has been implemented with 1.2 m 5GHz BiCMOS technology. The maximum conversion speed is 350Msamples/s. and dissipates only 900mW.

1. 벼 재배기간에 단동 지역의 평균기온은 북한의 신의주보다 약간 낮게, 수풍보다는 약간 높게 경과하였으며, 이들세 지역의 일장 변화는 거의 동일하였다. 2. 시험 연도와 이앙시기에서 공통적으로 단동 지역의 안전출수한계기와 현지 품종 중 가장 늦은 출수기까지 출수한 국내 품종은 조생종 8개(진부올, 백일미, 조운, 진옥, 조평, 진부, 산호미, 오대)였으며, 북한 품종은 5개(올벼2, 선봉9, 온포1, 길주1, 평도15)였다. 3. 국내 13품종과 북한 7품종의 기본영양생장성은 12~43 일, 감광성은 3~56일, 감온성은 15~33일 범위였는데, 국내 중생 및 중만생 3품종(선품, 신보, 소비)과 북한 평양21은 감광성이 33~56일로 컸고, 다른 3품종(아세미, 진미, 평도5)은 기본영양생장성이 40~43일로 큰 특징을 보였다. 4. 단동 시험포장에서 나타난 벼 품종의 출수기는 감광성과고도로 유의한 정의 상관을 나타내었으며, 감광성이 컸던 중생과 중만생 3품종을 제외하면 기본영양생장성과유의한 정의 상관관계가 인정되었다. 5. 단동 지역의 벼 재배기간에 적응하는 품종은 기본영양생장성 35일 이하와 감광성 25일 이하를 모두 충족하는 출수생태 특성을 보였다. We examined the heading responses of rice varieties over two years in Dandong, China to select the varieties that are adaptable to the bordering northwestern plains of North Korea. Dandong had slightly lower mean temperature than Sinuiju, North Korea but slightly higher than Supung, but it had almost the same day-length as the two regions in North Korea. In the two experimental years and two transplanting-date treatments, eight varieties (Jinbuol, Baegilmi, Joun, Jinok, Jopyeong, Jinbu, Sanhomi, and Odae) from South Korea and five varieties (Olbyeo2, Sonbong9, Onpo1, Gilju1, and Pyongdo5) from North Korea reached the heading stage not later than the latest heading dates of Dandong domestic varieties and the safe marginal heading dates of Dandong. We examined the basic vegetative phase (BVP), photoperiod-sensitivity (PS), and thermo-sensitivity (TS) of rice heading in a phytotron study to characterize the heading ecotypes of rice varieties adaptable to Dandong. For the rice varieties grown in Dandong experimental field, number of days to the heading stage was highly positively correlated with PS and, except middle and mid-late maturing three varieties, it was significantly positively correlated with BVP. Two-dimensional distribution plotting revealed that both 35 days or less BVP and 25 days or less PS were the characteristic heading ecotypes of the rice varieties adaptable to Dandong.

수확과정에서 버려지고 있는 고구마 잎을 이용한 기능성 식품소재로서 활용가능성을 검토하고자, 밀가루 중량 대비 고구마 잎 분말을 2, 3, 5, 7%의 비율로 첨가하여 식빵을 제조하고, 반죽 및 제빵 특성, 생리활성 및 기능성분 등을 조사하였다. 반죽의 수분흡수량은 7% 첨가 시 가장 높았고, 반죽시 간은 유의적인 차이를 보이지 않았으며, 반죽의 저항도는 2~3% 첨가할 때가 가장 안정적이었다. 식빵의 수분 함량은 첨가량이 증가하여도 큰 차이를 보이지 않았고, 식빵의 내부색은 첨가량이 증가할수록 L값과 a값은 감소하였으나, b값은 증가하였다. 식빵의 부피와 비용적 및 굽기 손실률은 첨가량이 증가할수록 감소하였으나, 항산화 활성과 총 폴리페놀, 루테인 및 베타카로틴 함량은 증가하였다. 관능평가의 결과, 고구마 잎 분말의 2~3% 첨가 시 맛과 색깔, 조직감, 입안에서의 씹힘성과 종합적인 기호도에서 가장 우수한 값을 얻었다. 이상의 결과에서 고구마 잎 분말의 2~3% 첨가 시, 제빵 적성과 기능성, 상품성이 우수한 식빵을 제조할 수 있었다. This study was carried out to investigate the quality characteristics of bread containing sweetpotato (Ipomoea batatas (L.) Lam) leaf powder (0, 2, 3, 5, and 7% of the total flour). We found that the addition of sweetpotato leaf powder decreased the pH of the dough, whereas the total titratable acidity increased and the specific volume and baking loss of bread were decreased. However, the moisture content of the bread did not show any significant differences. The L and a values of the bread inner crumb were decreased by the addition of sweetpotato leaf powder, however, the b value was increased. The 2,2-diphenyl-1-picrylhydrazyl-radical scavenging activity, total polyphenol, lutein and ${\beta}-carotene$ contents were increased significantly by the addition of sweetpotato leaf powder. The taste, color, flavor, chewiness and overall acceptability of bread containing 2~3% sweetpotato leaf powder were better than those of the controls. We found that the sample group with 2~3% sweetpotato leaf powder is the optimum content for making bread.

Recently, problems with excessive vibration of the radar masts of large bulk carriers and crude oil tankers have frequently been reported. This paper explores a design method to avoid the resonance of a radar mast installed on a large ship using various design of experiment (DOE) methods. A local vibration test was performed during an actual sea trial to determine the excitation sources of the vibration related to the resonant frequency of the radar mast. DOE methods such as the orthogonal array (OA) and Latin hypercube design (LHD) methods were used to analyze the Pareto effects on the radar mast vibration. In these DOE methods, the main vibration performances such as the natural frequency and weight of the radar mast were set as responses, while the shape and thickness of the main structural members of the radar mast were set as design factors. From the DOE-based Pareto effect results, we selected the significant structural members with the greatest influence on the vibration characteristics of the radar mast. Full factorial design (FFD) was applied to verify the Pareto effect results of the OA and LHD methods. The design of the main structural members of the radar mast to avoid resonance was reviewed, and a normal mode analysis was performed for each design using the finite element method. Based on the results of this normal mode analysis, we selected a design case that could avoid the resonance from the major excitation sources. In addition, a modal test was performed on the determined design to verify the normal mode analysis results.

보리 도정이 Fusarium 곰팡이독소 저감에 미치는 효과

백슬기,이미정,나주영,임수빈,최정혜,최장남,장자영,양정욱,이데레사,Seul Gi Baek,Mi-Jeong Lee,Ju-Young Nah,Soo Bin Yim,Jung-Hye Choi,Jang Nam Choi,Ja Yeong Jang,Jung-Wook Yang,Theresa Lee 한국식물병리학회 2023 식물병연구 Vol.29 No.4

곡류의 도정은 곰팡이독소의 분포에 영향을 줄 수 있다. 보리에서의 도정효과를 조사하기 위해 트리코테씬과 제랄레논 독소에 오염된 겉보리 7점과 쌀보리 4점을 일반적으로 사용하는 도정 비율에 따라 도정하였다. 두 종류의 보리는 데옥시니발레놀과 아세틸 유도체(98.1-2,197.8 ㎍/kg), 니발레놀과 아세틸 유도체(468.5-3,965.1 ㎍/kg), 제랄레논(4.1-274.2 ㎍/kg) 등에 동시에 오염되어 있었다. 겉보리를 67%로 도정한 결과 데옥시니발레놀은 90.9%, 니발레놀은 87.7%, 제랄레논은 93.2%가 각각 감소하였다. 70%로 도정한 쌀보리의 경우는 데옥시니발레놀 88.6%, 니발레놀 80.2%, 제랄레논 70.1%이 각각 감소하였다. 두 보리 모두 데옥시니발레놀과 니발레놀의 아세틸 유도체는 100% 감소하였다. 그러나 보리겨는 도정 전 보리에 비해 곰팡이독소가 크게 증가하였다. 겉보리의 겨에서는 데옥시니발레놀, 니발레놀, 제랄레논이 각각 평균 357%, 252%, 169% 증가하였다. 이와 유사하게 쌀보리의 겨에서는 데옥시니발레놀, 니발레놀, 제랄레논이 각각 337%, 239%, 554% 증가하였다. 이러한 결과는 보리 낟알의 외피에 존재하는 곰팡이독소가 도정 과정을 통해 효과적으로 제거될 수 있음을 나타낸다. 그러나 도정을 통해 곰팡이독소가 낟알에서 겨로 집적됨에 따라 보리겨를 인축에 활용하기 위해서는 사전에 독소의 오염 수준을 확인할 필요가 있음을 보여준다. Milling can affect the distribution of mycotoxins in small grains. To investigate the effects on barley, seven hulled barley and three naked barley samples naturally contaminated with trichothecenes and zearalenone were obtained and milled at commonly used rates. Both barleys were simultaneously contaminated with deoxynivalenol and its acetyl derivatives (98.1-2,197.8 ㎍/kg), nivalenol and its acetyl derivative (468.5-3,965.1 ㎍/kg), and zearalenone (4.1-274.2 ㎍/kg). Milling hulled barleys at a rate of 67% reduced the mycotoxins in the grain by 90.9% for deoxynivalenol, 87.7% for nivalenol, and 93.2% for zearalenone. The reduction in naked barleys (milled at a rate of 70%) was slightly lower than in hulled barleys, with 88.6% for deoxynivalenol, 80.2% for nivalenol, and 70.1% for zearalenone. In both barleys, the acetyl derivatives of deoxynivalenol and nivalenol were reduced by 100%. However, barley bran had significantly higher mycotoxin concentrations than the pre-milled grains: bran from hulled barley had a 357% increase in deoxynivalenol, 252% increase in nivalenol, and 169% increase in zearalenone. Similarly, bran from naked barley had a 337% increase in deoxynivalenol, 239% increase in nivalenol, and 554% increase in zearalenone. These results show that mycotoxins present in the outer layers of barley grain can be effectively removed through the milling process. As milling redistributes mycotoxins from the grain into the bran, however, it shows that advance monitoring of barley bran is recommended when using barley bran for human or animal consumption.
