CEPA를 답전작 및 우기전에 수확이 가장 빨리 촉진되면 또 니코친 함량이 저감되는지를 알고저 Yellow Special A 품종을 공시하여 적심 직후해당 농도의 CEPA 수용액을 살포한 후 일정기간을 두고 수확하여 처리수준별 성숙도 및 전 alkaloid함량을 조사하였던 바 그 결과는 다음과 같았다. 1) 처리농도가 높을수록 잎담배 성숙에 미치는 효과가 컸으며 그 효과는 처리 후 6-11일간에 있어서 현저하였다. 2) CEPA는 엽표면에만 처리해도 효과가 있으며 성숙촉진효과는 처리부분에 있어서 더욱 뚜렷하였다. 3) 처리농도가 높을수록 잎담배의 전 alkaloid 함량이 감소되는 경향이 있으며 그 효과는 성숙촉진작용후에 더 크게 나타났다. 4) CEPA의 성숙촉진작용은 성수기에 가까운 하부엽에서 컸고 alkaloid 축적억제작용은 반대로 숙기에 도달하지 않은 상부엽에서 컸다. 그러나 적기수확엽에 있어서는 축적억제효과가 부위에 관계없이 같았다. 5) CEPA 처리는 수량에 변화를 주지 않았으며 시용 적정농도는 500-2,000ppm 사이라고 느껴졌다. 6) CEPA의 성숙촉진 및 alkaloid 합성억제작용의 기구에 관하여는 금후 더욱 연구할 필요가 있다고 보았다.

Polarization of the light reflected off the Moon provides information on the size and composition of the particles in the lunar regolith. The mean particle size of the regolith can be estimated from the combination of the albedo and degree of polarization, while the color ratio of the parallel-component polarization (CP) has been suggested to be related to the amount of nanophase metallic iron (npFe^0) inside the regolith particles. Both the mean size and npFe^0 abundance of the particles have been used as maturity indicators of the regolith since sustained impacts of high energy particles and micro-meteoroids cause comminution of particles and production of npFe^0. Based on our multispectral polarimetric observations of the whole near side of the Moon in the U, B, V, R, and I bands, we compare the maps of the mean particle size, CP, and the optical maturity (OM). We find that the mean particle size map is sensitive to the most immature (~0.1 Gyr) soil, the OP map to the intermediate immaturity (a few 0.1 Gyr) soil, and the CP map to the least immature (~1 Gyr) soil.

Field experiment was conducted to get the basic information about the difference in color and plastid pigments at the different stage of harvest of flue-cured tobacco cultivated in paddy field, and compared to upland ones. All tested crops were primed in lots of 3 to 4 at each priming, beginning at the bottom of the plant. Leaf pigments and chromatic values of tobacco leaves were determined in samples collected at weekly intervals, and according to analyses obtained from 4 stalk positions. By the degree of maturity, leaves harvested were separated with visual characters into four classes of immature, mature, ripe and mellow. regardless of stalk position, chlorophyll contents was higher in the order of immature > mature > ripe > mellow, respectively. In fresh leaves, chlorophyll levels was higher with ascending stalk position. chlorophyll a and b in cured leaves were less than 10% of the amount present at harvest, and it was estimated that maturity condition also influenced the rates of degradation of plastid pigments. Fully mature leaves of upland diverted from paddy field showed slightly higher in chlorophyll contents than in those of upland tobacco ones but somewhat lowered in $L^*$ and $b^*$ values, and there was no difference in $a^*$ value.

This study presents a method of quality category classification by safety, maturity, complexity, and what types and extent of controls and verifications are applied to specific products and services during the various stages of a nuclear facility life cycle. All products, services and processes have various controls and verifications built in to ensure they perform their functions satisfactorily. The highest grade should require the most stringent application of the quality assurance requirements ; while, the lowest grade should require the least stringent. When products or services are modified, the assigned grade of quality assurance requirements could become more stringent or less stringent depending on the significance in nuclear safety. Applying QA program always costs money, and they should be applied and focused to the extent where necessary and not applied or applied to a lesser degree for less important activities. An efficient QA program should be developed to satisfy the necessary requirements and to ensure the required confidence in quality, but without unnecessary stipulations. Not all the requirements of QA standard must be applied identically to all products and services which are to be provided.

토마토의 색도를 측정하기 위해 색소의 sequential extraction을 이용한 spectrophotometric technique을 시도하였다. 파장 480nm 와 660nm에서 각기 80% acetone과 chloroform으로 추출된 용액의 흡광도를 합한 다음 두 파장에서의 총 흡광도 차이를 구한 결과 토마토의 숙성(ripening) 정도가 잘 반영되었다. 이러한 측정방법은 토마토 색소의 객관적 측정을 위한 간단하고 신뢰성 있는 방법으로 간주된다.

The emergence of new technologies and their implementation by different manufacturers of electronic devices are experiencing an ascending trend. Most of the time, these protocols are expected to reach a certain degree of maturity, and electronic equipment manufacturers use simplified communication standards and interfaces that have already reached maturity in terms of their development such as ModBUS, KNX or CAN. This paper proposes an IoT solution of the Smart Home type based on an Analysis and Prediction System. A data acquisition component was implemented and there was defined an algorithm for the analysis and prediction of actions based on the values collected from the data update component and the data logger records.

Objectives Five cases of early puberty patients were diagnosed and treated according to Sasang constitutional medicine. Methods Seven year-old girl and four nine year-old girls visited the children's development clinic and were diagnosed as Sasang constitutional types according to clinical investigations. Their breast stages were in the 2nd degree of SMR(sexual maturity rating). Three were Taeeumin and two were Soeumin, so they were prescribed according to their Sasang constitutional types and complaints. Results and Conclusions It could show that early puberty patients can be given treatments and managements according to Sasang constitutional medicine.

조류가 식물 열매의 성숙도와 크기에 따라 어떻게 선택하는지를 알아보기 위하여 사육 중인 3종의 새에게 성숙도와 크기가 다른 식물 3종의 열매를 주어 그 먹는 양을 계수하고, 다변량통계로 분석하였다. 실험에 사용한 새는 금계(Chrysolophus pictus, 꿩과), 양비둘기(Columba rupestris, 비둘기과)와 자바공작 (Pavo muticus, 꿩과)이고, 열매는 왕벚나무(Prunus yedoensis, 장미과), 뜰보리수나무 (Elaeagnus multiflora, 보리수나무과)와 아그배나무(Malus sieboldii, 장미과)의 각각 3종류이다. 금계는 3종 열매에 관계없이 열매의 성숙도와 크기에 따른 뚜렷한 섭식 선호도를 보이진 않았다. 양비둘기는 왕벚나무와 뜰보리수나무는 열매의 크기에 관계없이 설익은 열매를 선호하기는 하나 아그배나무 열매는 크기나 성숙도에 따른 차이가 없었다. 공작은 왕벚나무와 뜰보리수나무 열매의 경우 크기에 관계없이 익은 열매를 선호하기는 하지만 아그배나무 열매에 대해서는 크기나 성숙도에 관계없이 거의 섭식하지 않았다. 새들 3종은 초기에 섭식 빈도가 높은 열매를 후기에도 많이 섭식하는 것으로 나타났다. 이상으로 볼 때 조류가 열매를 선택함에 있어서 열매의 종류에 따라 다르다는 것을 알 수 있었다. 그러나 열매의 크기에 따른 선호도는 차이가 없었다. 또한 조류가 먹이를 먹는 양은 초기 선택에 의해 결정된다고 판단된다.

본 연구는 IT 아웃소싱에 미치는 영향요인과 도입성과를 실증적으로 분석하였다. IT 아웃소싱에 미치는 영향 요인은 조직요인(정보시스템 성숙도, CEO의 지원), 거래요인(자산 특수성, 불확실성, 정보시스템의 사용정도), 위험요인(안전성(보안)의 위험, 비용의 증가위험, 자율성 상실의 위험)으로 설정하였다. 분석 결과는 다음과 같다. 조직요인에서 정보시스템 성숙도와 CEO의 지원요인은 도입성과에 긍정적인 영향을 미치는 변수로 분석되었고, 거래요인에서는 정보시스템 사용정도 변수만이 도입성과에 영향을 미치는 변수로 분석되었으며, 자산의 특수성 요인과 불확실성 요인은 도입성과에 영향을 미치지 않는 것으로 분석되었다. 위험요인에서는 안전성(보안)의 위험, 비용의 증가 위험 요인만이 도입성과에 영향을 미치는 변수로 분석되었고, 자율성 상실의 위험요인은 도입성과에 영향을 미치지 않는 것으로 분석되었다.

In this study, canonical correlation analysis (CCA) was applied to estimate the relationship between three different sexual maturity traits (X set: days to first egg (DFE), weight of the first egg (WFE), body weight at first egg (BWFE)) and level of nutrient intake (Y set: energy (EI) and protein intake (PI)) or the egg production traits at two different periods (Z set: number of egg (NE1 and NET) and weight of egg (WE1 and WET) from 22 to 25 (Wfirst) and 22 to 33 wk of age (Wall), respectively), which were measured from 64 egg-type pullets (Isa Brown) manipulated for time of access to energy and protein sources to onset of egg production. Partial CCA (PCCA) was used to eliminate the contribution of differences in the levels of nutrient intake to canonical variables for X and Z sets at the first production period. Estimated canonical correlation coefficients between X set and Y set (0.429, p = 0.042), X set and Z set (0.390, p = 0.007 for Wfirst) and within Z set (between Wfirst and Wall; 0.780, p<0.001), and partial canonical correlation coefficient between X set and Z set (0.415, p = 0.009) were significant. Canonical weights and loadings from CCA indicated that the BWFE had the largest contribution compared to the DFE and WFE to variation of egg number produced at two different periods. The results from PCCA indicated that the contribution of PI and EI to the degree of the correlation between canonical variables for X and Z sets were unfavourable. In conclusion, the effect of body weight at sexual maturity upon the availability of nutrients can have a higher contribution to variation of egg production in pullets if the contribution of differences in nutrient intakes to onset of egg production were eliminated.
