김기준,김광호,김영희,Kim, K.J.,Kim, K.H.,Kim, Y.H. 한국작물학회 1981 Korean journal of crop science Vol.26 No.3

파종기이동에 따른 콩, 팥, 녹두의 개화기분포와 결협율의 변이를 알기 위하여 중부지방에서 널리 재배되고 있는 품종 하나씩을 공시, 5월 10일, 6월9일, 7월 9일 파종구 및 5월 10일 파종후 단일 처리한 구를 두어 시험한 결과를 요약하면 아래와 같다. 1. 각 처리별 개화까지의 일수, 개화기간 그리고 개화시에서 정엽출현까지의 일수를 비교한 결과 공시된 중 품종은 유한신육형에 그리고 팥과 녹두는 무한신육형에 속하는 것이었다. 2. 주당개화수 및 성숙협수는 3작물이 모두 7월9일 파종구 및 단일처리구에서 현저히 감소되었으나 결협율은 파종기에 따라서 일정한 경향 없이 콩 38\sim48%, 팥 23\sim34%, 그리고 녹두 46\sim60%였는데 콩과 녹두는 낙화 그리고 팥은 낙협이 각각의 결협률에 더 큰 영향을 주었다. 3. 콩은 어느 파종구에서든지 1회의 개화성기를 보인 반면 팥과 녹두는 극만파구민 7월9일 파종구를 제외하고는 2\sim3회의 개화성기를 보였고 개화최성기는 콩이 개화시로부터 10일 이내에 왔으나 팥과 녹두는 파종기에 따라서 개화시로부터 25\sim45일 사이에 왔다. 4. 개화기에 따른 성숙협수의 분포는 모든 처리구에서 개화분포와 비슷한 경향을 보였고 콩의 결협율은 개화최성기 직후에 핀 꽃들이 가장 낮았으며 그 이전 및 이후에 핀 꽃들이 점점 높은 값을 보였다. 팥과 녹두의 결협율은 각 개화성기 직전에 된 꽃들이 높았고 그 직후에 핀 꽃들이 낮은 값을 보였는데 7월 9일 파종구는 3작물에서 모두 시기적으로 늦게 핀 꽃일수록 결협률이 낮아졌다. 5. 중은 모든 파종구에서 정엽출현일을 전후로 한 5일 동안에 개화최성기를 보였으며 정엽전개 이전에 핀 꽃 및 여기서 생긴 성숙협수가 더 큰 비중을 차지한 반면 팥과 녹두는 정엽출현기와 개화 또는 결협간에 아무런 관계도 없었고 정엽전관 이후에 더 많은 꽃을 피웠다. Soybean, azuki-bean and mungbean were cultivated at different growing conditions, May 10, June 9, July 9 seeding, and May 10 seeding-short day treatment, to investigate the distribution of flowering date and the variation of pod/flower ratio. The growth habit type of the soybean variety used was determinate, but the azuki-bean and mungbean varieties used showed indeterminate growth habit. The pod/flower ratio ranged 38 to 48% for soybean, 23 to 34% for azuki-bean and 46 to 60% for mungbean along with growing conditions. Flower abscission for soybean and mungbean, and pod abscission for azuki-bean affected more on the number of matured pods. Soybean showed once full blooming period, but azuki-bean and mungbean showed two or three times full blooming period except July 9 seeding plot through the whole growing period. Flowers bloomed just after every full blooming period showed lower value of pod/flower ratio and higher pod/flower ratio was obtained from flowers bloomed before or far after full blooming at plots seeded May 10 and June 9 in three pulse crops. Most full blooming period of soybean coincided within 5 days near the terminal leaf appearance date, and number of flowers bloomed before terminal leaf expansion and matured pods from these flowers were major in every soybean plant at all growing codition plots. No relations were found between terminal leaf appearance and flowering or pod setting patterns of azuki-bean and mungbean.

김기준,성기천,이후설,Kim, Ki-Jun,Sung, Ki-Chun,Lee, Hoo-Seol 한국응용과학기술학회 1996 한국응용과학기술학회지 Vol.13 No.3

Thermograms of methylene blue(MB) in $L-{\alpha}-lecithin$ vesicle and incorporated purple membrane vesicle(InPM) systems have been studied by photochemical reaction differential scanning calorimetry at $25{\sim}55^{\circ}C$. Phase transition temperatures of lecithin vesicle, purple membrane(PM), and InPM were found to be independent of illumination of light(436nm) at $39{\sim}40^{\circ}C$, but endothermic phase transition was found in InPM vesicle. In MB-InPM system, endothermic phase transition was found on unillumination of light at $40{\sim}42^{\circ}C$, but exothermic phase transition was found on steady illumination of light at $48{\sim}52^{\circ}C$. It was estimated that the light energy absorbed from MB on vesicular surface was transferred to PM, and the transferred energy was redistributed to hydrophobic site of membrane. Therefore, the exothermic phase transition was measured at high temperature because of the increased hydrophobicity of acyl chain.

In this paper, it tried to develop the core sensor for detection of micro magnetic field in electric wires. The sensor is non contact type and is consisted of ferrite core for low price. To investigate their properties for variations of current, it changed the number of winding and the length of sample core, it examined, to check the live wire situation in built-in wires, electrical characteristics due to difference between electric wires and core sensor. As the results, it verified live wire situation at the number of winding(5,000) and within length of 6[cm]. Also, it obtained magnetic field magnitude decreased inverse proportion ratio to a square about difference between electric wires and core sensor.

Commonly, a live-line alarm can be used to measure the electric field strength of a high-voltage system to calculate its current, but it is hard to detect the electric field of shielded cables or concealed structures, such as underground distribution cables. Current sensors can detect the magnetic field in a single core wire, but they cannot determine the magnetic field about a double-core wire because the currents flow in opposite directions. Therefore, it is very difficult to detect certain current problems, such as a fault current in an extension line comprised of a double line. In this paper, to ultimately develop a sensor that can detect the current regardless of line conditions, we used a simulation to determine the concentration of the magnetic field dependent on the distribution of the external magnetic field and the path of each line's core.

Objectives: We investigated weight gain effects of the Bofesungjangjeungbo-tang ($B\check{u}f\grave{e}ich\acute{e}ngzh\check{a}ngz\bar{e}ngb\check{u}$-tang) on thin Korean preschool children with frequent common cold or chronic rhinitis Methods Bofesungjangjeungbo-tang was empirically composed of 14 herbs for treating indigestion, and common cold or chronic rhinitis. We analyzed 60 preschool children who have visited Kim Kijoon Oriental Clinic BOM from Jan. 1, 2006 to Aug. 31, 2011 with three criteria: 1) 2~5yrs of age and BMI<50th percentile 2) children those who had taken the Bofesungjangjeungbo-tang for 1~3 month (s), 3) Availability of records on before/after treatment within 3 months. Weight gain of the children after treatment was evaluated by the changes of BMI percentile compared to pre-treatment. Results Bofesungjangjeungbo-tang significantly improved BMI percentile in all groups (1 month: $21.33{\pm}10.04$ vs $26.43{\pm}13.16$, p<0.001; 2 months: $21.90{\pm}10.28$ vs $29.03{\pm}15.06$, p<0.001; 3 months: $19.06{\pm}10.04$ vs $35.71{\pm}17.40$, p=0.001). Gender, age and pre-treatment BMI had no significant effects on the effectiveness of Bofesungjangjeungbo-tang. Conclusions: Bofesungjangjeungbo-tang positively affected weight gain in 2~5yrs Korean preschool children with BMI below 50 percentile within 1~3 month (s) of treatment. However, additional studies on functional dyspepsia or the change of energy intake are needed to understand the factors related to weight gains.

NATM의 미세 구조는 SEM, FT-IR, 인장특성, 그리고 [NCO]/[OH]의 mole %, 입도분석에 의해 측정하였다. 친환경적인 NATM에 관한 관심이 고조됨에 따라 스테인레스 등의 금속코팅에 더욱더 중요한 무용제 도료의 발전을 이끈다. 우리는 스테인레스 스틸의 부식을 방지할 수 있는 NATM(New Austria Tunnel Method)의 수지를 합성하였다. 폴리우레탄과 에폭시로 합성한 혼성 수지는 일반적 NATM 수지와 도료와 비교하여 강도와 내구력이 매우 양호하다. 혼성수지는 폴리올, 에폭시, MDI, 실리콘 계면활성제, 촉매, 가교제, 충전제로 구성된다. 충전제인 fume silica는 경화속도를 가속시킬 뿐만 아니라 열적 장벽으로 물성이 우수함을 나타냈다. NATM 수지의 기계적 특성은 [NCO]/[OH]의 mole%와 fume silica가 증가함에 따라 강도가 증가하였다. 결론적으로 가교제와 fume silica가 함유된 혼성수지의 미세구조는 스테인레스 스틸같은 금속물질의 열경화코팅을 위한 좋은 물질이다. The microstructures of NATM were examined by SEM, FT-IR spectra, tensile properties, mole % of [NCO/OH], and particle size analyzer. Growing concerns in the environment-friendly industries have led to the development of solvent-free formulations that can be cured. We had synthesized NATM(New Austria Tunnel Method) resin having the ability to protect stainless steel against corrosion. Comparing with general NATM resin and coatings, this resin that synthesized with polyurethane and epoxy was highly stronger in intensity and longer durability. Hybrid resin was composed of polyols, MDI, epoxy, silicone surfactant, catalyst and crosslink agent, and fillers. Moreover, fillers such as fume silica not only accelerated the curing rate but also improved the physical property as thermal barriers. The rigid segments of synthetic resin in mechanical properties were due to fume silica and the increase the mole% of [NCO/OH] for corrosion protection. In conclusion, the hybrid resin microstructure with crosslink agent and fume silica are good material for thermosetting coating of metal substrates such as stainless steel.
