In order to evaluate the relationship between low temperature-induced photoinhibition and winter survival in wheat, seeds of 20 chromosome substitution lines and their parents, Chinese Spring and Cheyenne were germinated at 20℃ and were transferred to 5/2℃ and 20/16℃ growth chambers to obtain cold-acclimated (CA) and nonacclimated (NA) plants, respectively. For photoinhibition and recovery experiments, 7 to 8cm long leaf portions were placed on moist filter paper and placed in trays at 5℃ cold room with 1,100 μmol m⁻² s⁻¹ PPFD. Room temperature chlorophyll fluorescence was measured with a PAM system after 50 minute dark adaptation. Instantaneous Fo, Fv, and Fm were determined and the Fv/Fm, was calculated. Fv/Fm of CA plants were reduced from 0.81 in control leaves to 0.33 following photoinhibition of 8h and the CVs were increased from 1% to 19%. Fv/Fm of NA plants were reduced from 0.82 in control leaves to 0.39 in leaves exposed to 5℃ for 6h, and the CVs were increased from 0.5% to 15%. Thus, photoinhibition of CA plants was less than that of NA plants. Fv/Fm of freezing tolerant Cheyenne grown under either CA and NA conditions, were higher than those of freezing-sensitive Chinese Spring. Chinese Spring lines substituted with Cheyenne chromosome 5(5A, 5B and 5D) showed relatively higher resistance to photoinhibition. A series of studies suggests that the chromosomes of homologous group 5 of Cheyenne have major genes controlling freezing tolerance, expression of antifreeze proteins and factors resistant to low temperature-induced photoinhibition. Winter survival in wheat was positively correlated with resistance to photoinhibition of PSⅡ and significantly fitted by multple linear regression(R²=0.75∗∗). Also, winter survival in wheat was positively correlated with resistance to photoinhibition of PSⅡ and expression of antifreeze proteins, and significantly fitted by multple linear regression (R²=0.76∗∗). Variable chlorophyll fluorescence measured by Fv/Fm has been found to be very useful in evaluating relative levels of freezing tolerance in wheat.

본 연구는 임해준설매립지반의 토양환경에서 4종의 조경수종을 대상으로 생장 및 적응성을 평가하였다. 준설토와 조경토를 1:1로 혼합하여 1m 높이로 조성한 식물재배 실험구(planting pilot system)기반 토양의 토성은 사질토(S)로 분류되었고, 평균 pH값은 7.16으로 약알칼리성을 나타내었으며, 전기전도도(EC)는 294 ${\mu}S/cm$로 해수의 영향을 받았던 토양이었으나 비교적 낮은 EC값을 보였다. 토양의 유기물 함량은 3.9%로 낮았고, 총질소 함량은 397 mg/kg에 가깝게 나타났으며, 인산의 평균함량은 4.60 mg/kg으로 매우 낮아 식물의 생장을 돕기 위해서는 계획적인 인산질 비료의 시비가 필요한 것으로 사료되었고, 토양의 치환성 양이온 함량은 K가 152.9 mg/kg, Ca가 1,190 mg/kg, Mg가 62.7 mg/kg, Na가 24.8 mg/kg으로 비교적 높은 함량을 나타내었다. 식재후 4년인 비교년도의 식물재배 실험구에서 식재조건에 따른 생장수고는 물오리나무>사방오리>곰솔>피라칸사 순으로 나타났고, 흉고직경은 물오리나무>사방오리>곰솔 순으로 나타났다. 사방오리, 물오리나무, 곰솔 및 피라칸사 개체당 열매, 잎, 가지, 줄기, 주근, 중근 및 세근의 식물량은 고밀도보다 저밀도 식재지역에서 높게 나타났고, 고밀도와 저밀도 식재지역에서 개체당 식물량은 물오리나무>사방오리>곰솔>피라칸사 순으로 나타났다. 식물재배 실험구에서 4종 모두 고밀도보다 저밀도 식재지역에서 개체당 식물량은 물질생산 및 분배가 크게 반영된 생육양상을 보여 약 2배 높았다. 이는 토양 내의 영양염류의 이용경쟁에 있어 고밀도보다 저밀도 식재지역에서 더욱 유리한 조건이 반영되었기 때문으로 판단되었다. 단위면적당 식물량은 물오리나무>p사방오리>곰솔>피라칸사 순으로 나타났고, 식물량이 가장 적은 피라칸사 기준으로 곰솔은 약 7배, 사방오리는 약 13배, 그리고 물오리나무는 약 23배 높은 식물량을 나타내었다. 식재조건에 따른 실험 수종 개체당 식물량은 고밀도보다 저밀도 식재지역에서 약 2배 높은 것으로 나타났지만, 단위면적당 식재조건에 따른 식물량은 저밀도보다 고밀도 식재지역이 비슷하거나 높았다. 고 저밀도 식재지역에서 오리나무속의 식물들이 많은 식물량을 보였는데, 이는 임해준설매립지의 토양 특성에 잘 적응성을 나타냄과 동시에 질소 고정능력을 갖는 속성수(fast-growing tree)의 특성 및 지하부에 뿌리혹박테리아(root nodule bacteria)가 형성됨으로써 토양에 불용성 영양원의 이용도를 높일 수 있는 능력이 있기 때문으로 판단되었다. 본 연구는 제한된 부지를 대상으로 4종의 식물만을 이용하여 연구가 진행되었기 때문에 다양한 식재조건 및 수종을 대상으로 하는 추가적인 연구가 필요하고, 조경분야의 생태적 활용을 위해서는 대상 식물들을 이용한 조경학적 적용방안에 대한 연구가 보완되어야 한다. To investigate the possible use of plants for landscaping in reclaimed soil, a planting pilot system experiment was performed over the course of four years in reclaimed dredging area with four species: Alnus firma, Alnus hirsuta, Pinus thunbergii, and Pyrachantha angustifolia for 4 years. The physicochemical characteristics of the tested soil showed that it was sandy through coming from a reclaimed dredging area. The average pH of the tested soil was 7.16(slight alkali), and electric conductivity(EC) was relatively low, $294{\mu}S/cm$, even though it came from a saltwater area. To test the effect of planting density vs. phytomass by plant specie from a planting basin, the experiment was designed using four plant species with high and low planting densities over 4 years. The planting conditions of the growth of landscape tree species exhibited growth height as follows: A. hirsuta, A. firma, P. thunbergii, and P. angustifolia, whill the DBH followed the order of A. hirsuta, A. firma, and P. thunbergii. The total phytomass of each plant was higher at low density planting areas than high density planting area in terms of total phytomass production and growth distribution in the reclaimed dredging area. Total phytomass per unit area increased as follows: A. hirsuta, A. firma, P. thunbergii, and P. angustifolia. The total phytomass per each tested plant was 2 times higher in low density planting areas than high density planting areas. Total phytomass per unit area, however, was similar or slighty higher in high density planting areas compared to low density areas. Among the tested plants, A. hirsuta showed the highest phytomass, implying that A. hirsuta adapted very well to the reclaimed area and has the capability of a fast growth, nitrogen fixation tree, and utilizing insoluble nutrients through inoculated root nodule bacteria. The yield of phytomass per individual in low density Alnus species was greater than that of the high density. However, those per unit areas had no difference in the density-dependent planting. The ratio of belowground to aboveground was $0.21{\sim}0.26$. Thus, it could be concluded that the Alnus species are potential candidates for ornamental tree species in reclaimed dredging areas. This study offers baseline data for the use of ornamental tree species in reclaimed dredging areas. Additional research is required for different ornamental species in order to increase phytomass of a planting conditions based on reclaimed dredging areas.

국어 방언의 이화 현상에 대한 한 고찰

정인호(Jeong, In-ho) 우리말글학회 2020 우리말 글 Vol.87 No.-

본고는 여러 방언형들을 종합적이고 면밀하게 검토함으로써 비음 ‘ㅇ, ㅁ’과 관련된 이화 현상의 성격을 규명하는 데에 목적을 둔다. 국어 방언들에서 연구개 비음 ‘ㅇ’과 양순 비음 ‘ㅁ’은 ‘이, j계 상승이중모음’을 사이에 두고 각각 연구개음 ‘ㅇ, ㄱ’과 양순음 ‘ㅁ, ㅂ’이 후행할 때 탈락(혹은 비모음화)하거나 ‘ㅇ/ㅁ>ㄴ’의 변화를 경험한다. 한자어에서만 일어나는 ‘ㅇ, ㅁ’의 변화는 동일한 조음위치의 자음 앞에서 일어나는 동기관적 이화이다. 그리고 1차적 변화는 ‘ㅇ, ㅁ’에 의한 비모음화인데 이는 발음을 편하게 하려는 노력의 결과이다. 다음으로 2차적 변화는 두 방향으로 나뉘어 방언 분화를 야기하게 된다. 첫 번째 방향은 비모음의 [비음성]마저 상실되어 완전한 ‘ㅇ, ㅁ’의 탈락으로 이어지는 약화이다. 그리고 두 번째 방향은 [j˜Ṽ, ĩ]가 [ɲṼ, ɲĩ]로 바뀌는 강화이다. This paper aims to clarify the nature of the dissimilation related to nasal ‘ŋ, m’ by comprehensively and closely reviewing various Korean dialectal forms. In Korean dialects, the velar nasal ‘ŋ’ is deleted(or vowel-nasalized) or experiences change of ‘ŋ>n’, when the sound sequence of ‘j-type rising diphthongs’ and velar ‘ŋ, k’. Also the bilabial nasal ‘m’ is deleted(or vowel-nasalized) or experiences change of ‘m>n’, when the sound sequence of ‘i, j-type rising diphthongs’ and bilabial ‘m, p’. The changes of ‘ŋ, m’ in the Chinese words are dissimilations that occurs before the consonants at the same place of articulation. And the primary change is vowel-nasalization by the ‘ŋ, m’, which is the result of efforts to make pronunciation easier. Next, the secondary change is divided in two directions, causing dialectal divergence. The first direction is the lenition that leads to the complete deletion of the ‘ŋ, m’ by losing ‘nasalness’ of the nasal vowel. And the second direction is fortition in which [j˜Ṽ, ĩ] change into [ɲṼ, ɲĩ].

전남 화순지역어에서의 운율 및 그와 관련된 음운변화

정인호(Jeong In-Ho) 국어국문학회 2005 국어국문학 Vol.- No.140

In the Hwasun dialect, each prosody performs expressive, referential, and conative function. The accent type is pitch-length accent which has been transformed from pitch accent. Phonetically, high-pitched vowels show a strong tendency to lengthen, and long vowels are apt to be devoiced.<br/> Diachronically, word-initial vowels have had tendency to lengthen. In verbs, vowel lengthening has occurred by means of complicated factors; paradigmatic simplification, analogy, sound change, etc.. In nouns and adverbs, the factor of lengthening, respectively, has been sound change and expressive length.<br/> The word-initial consonants in some adverbs have been aspirated. The change into aspirates has occurred by the realizations of the expressive long vowels as a high-pitched and furthermore devoiced.

소위 ‘비모음화’ 현상의 지리적 분포와 그 성격

정인호(Jeong In-ho) 우리말글학회 2007 우리말 글 Vol.41 No.-

This study aims to display the geographical distribution of the vowel nasalization and to elucidate the nature of it. The vowel nasalization of 'ŋ' is realized most vigorously in the Gyeongsang, east Gangwon, Hamgyeong, Pyeongan, and Hwanghae dialect, and the vowel nasalization of 'n', in the Gyeongsang dialect except for west area and Hamgyeong dialect except for Yukjin area. The distributional region that vowel nasalization of 'ŋ' is realized is wider. Phonetically, nasal vowels are different from nasalized vowels and vowel nasalization means that oral vowel is changed not to nasalized vowel but to nasal vowel. In the Korean dialects, only 'n, ŋ' are relevant to vowel nasalization. This phenomenon results not only from articulatory phonetic natures of consonantal 'n, ŋ', but also a articulatory domain of vowels. In the Korean dialects, vowel nasalization of both 'ŋ' and 'n' triggers the generation of new phonological rule, that is, velar-nasalization. As s result of it, phonological restructuring happens.

어감 표현과 전설모음화의 한 유형

정인호(Jeong, In-ho) 우리말글학회 2013 우리말 글 Vol.57 No.-

본고에서는 한국어 방언들에 ‘후설모음ː전설모음’의 어감 대립 체계가 형성되고 이 대립이 드러나는 전설모음화가 존재함을 확인하려 한다. 어감은 음색에 따른 미묘한 뉘앙스를 말의 의미에 결부시켜 감정을 표현하는 하나의 체계이다. 그리고 어감은 여러 가지 방식에 의해 표현될 수 있는데 그 주된 방식은 음을 변환시키는 것이다. 근래에 한국어 방언들에는 전통적인 모음 어감 대립 체계 외에, ‘초점’의 어감 차이를 보이는 ‘후설모음ː전설모음’이라는 새로운 어감 대립 체계가 형성되고 있다. 그리고 이 체계가 드러나는 전설모음화가 진행되고 있는데 이는 후설모음을 전설모음으로 교체하여 해당 단어의 의미와 제1음절 모음의 어감을 일치시킴으로써 그 정도성 의미를 강조하고자 하는 음운현상이다. This study aims to investigate the construction of the nuance opposition between back vowel and front vowel, and front-vowelization which this oppositional system is revealed in Korean dialects. One expresses emotions by means that relate subtle nuance to meaning of the words. The nuance is expressed in various manners, but the alternation a sound into another is principal. New system of nuance opposition between back vowel and front vowel, recently, has been constructed in addition to traditional system. The nuance of the front vowel is ‘focus’ sense. Besides, front-vowelization which this new oppositional system is revealed is in progress in Korean dialects. And this phonological phenomenon is the one that back vowels change into front vowel in order to place emphasis on the meaning of a certain word.

The anti-asthmatic activities of the extract of Lonicera japonica (BuOH fraction) and its mode of action were investigated using several in vitro and in vivo models. Lonicera japonica was extracted with 30% ethanol (v/v) and successively partitioned into BuOH. The BuOH fraction reduced antigen-induced contraction of isolated trachea from sensitized guinea pigs in a concentration-dependent manner. The BuOH fraction also inhibited histamine release from rat peritoneal mast cells induced by antigen or calcium ionophore A23187 ($IC_{50}=0.26$ and 0.32mg/ml, respectively). Eosinophil infiltration into bronchoalveolar lavage fluids induced by aeroallergen challenge in passively sensitized guinea pigs was inhibited by the BuOH fraction at a dose of 800mg/kg (51.7%). In addition, the BuOH fraction inhibited leukotriene $B_4$ prodution in rat basophilic leukemia cells ($IC_{50}=0.42\;mg/ml$) as well as phosphodiesterase 4 (PDE4) isolated from rat brain ($IC_{50}=0.015\;mg/ml$). All results from this study strongly suggest that the BuOH fraction of Lonicera japonica may be useful in the treatment of asthma and its mode of action may be related with inhibition of both 5-lipoxygenase and PDE4 enzyme.

This study was performed to determine the subacute toxicities of SKI306X, an antiinflammatory herbal extract, in rats. SKI306X was administered orally to rats once a day for 4 weeks at doses of 0.3, 1.0, and 3.0 g/㎏/ day. Each group consisted of 20 male and 20 female rats, including 5 male and 5 female rats per group for an interim study at the end of 2-week administration and for a 2-week recovery study, respectively. Throughout the study, all rats survived and no adverse clinical signs were observed. Although male rats treated with high dose (3.0 g/㎏/day) of SKI306X showed slight loss of body weight (approximately 5%) in comparison with control animals during the administration period, their body weight loss was normally restored during the recovery period. No significant change was found in all hematological parameters of SKI306X-treated groups except for the decreased number of red blood cells in all female groups at the interim study. Statistically significant changes were observed in several blood enzyme levels of SKI306X-treated groups; however, most of these significant changes were within normal range and statistically significant values did not show dose-related responses. In SKI306X-treated groups, the absolute and relative weights of liver, heart, and stomach were statistically different from those of control group, but these differences disappeared at the end of recovery period and also drug-related gross and histopathological findings in these organs were not found. No other drug-related gross and histopathological findings were observed. It is concluded from the results of this study that non-toxic dose of SKI306X was estimated to be between 0.3 and 1.0 g/㎏/day and the maximum tolerated dose of SKI306X was assumed to be higher than 3.0 g/㎏/day.
