Molecular markers are useful tools for evaluating genetic diversity and determining cultivar identity. Present study was conducted to evaluate the genetic diversity within a diverse collection of rice accessions used for Korean breeding programs. Two hundred eighty-seven rice cultivars, composed of temperate japonica, tropical japonica, indica, and Tongil-type of Korean crossing parents were evaluated by means of 15 simple sequence repeat (SSR) markers. A total of 99 alleles were detected, and the number of alleles per marker ranged from 4 to 11, with an average of 6.6 per locus. Polymorphism information content (PIC) for each of the SSR markers ranged from 0.2924 to 0.8102 with an average of 0.5785. These results, with the result that use of only 15 SSR markers made all rice cultivars examined could be uniquely distinguished, imply the efficiency of SSR markers for analysis of genetic diversity in rice. Cluster analysis was performed on similar coefficient matrics calculated from SSR markers to generate a dendogram in which two major groups corresponding to japonica (Group I) and indica and Tongil type rice (group II) with additional subclasses within both major groups. The narrowness of the Korean breeding germplasm was revealed by the fact that most of the Korean-bred and Japan-bred temperate japonica cultivars were concentrated into only 2 of the sub-group I-1 (143 cultivars) and I-2 (58 cultivars) among six sub-groups in major group of japonica. This is because of the japonica accessions used in this study was a very closely related ones because of frequent sharing of the crossing parents with similar genetic background with synergy effect of the inherited genetic difference between indica and japonica. A rice breeding strategy with the use of molecular markers was discussed for overcoming of genetic vulnerability owing to this genetic narrowness.

핵이동과 'NP이/가+V형' 복합동사 형성

宋福勝 순천대학교 어학연구소 1997 어학연구 Vol.8 No.-

The purpose of this paper is to account for the changes of syntactic structure and argument structure when the verb compounding occurred. In this paper, I limited the scope of discussion only to 'NPi/ka+V' type complex predicate(ie, 'honi-nata') and 'NP+V' type compound verbs like 'honnata(to be scolded)'. The verb compounding could be explained as a Syntactic Head Movement within the Principles and Parameter Theory. And the compound verbs formed by Head Adjunction interpreted as a unique word by Word Interpretation(WI) at LF, because it is a minimal projection X^min of V. Usually, the verbs which attend to the formation of compound verb are unaccusative verbs. So, the argument of this unaccusative verb is generated in complement position of the verb in D-structure. An unaccusative verb and it's noun with Nominative Case interacts morpho-semantically to form a new meaning, and this new meaning motivates to insert a new external argument. The change of argument structure, when the complex predicate formed, could be described as an 'Expansive Restructuring of Argument Structure' following after acquiring a new semantic feature. Therefore, when the compound verbs formed from this complex predicate, the argument structure is reductivly restructured. I expect to show both of 'honnata' type compound verbs and even 'sunbota' types could be expounded with this restructuring principle. Finally, this description could be generalized as one of general principles of Restructuring of Argument Structure, including compound verb formation and derivational passive verb formation.

The aim of this paper is to investigate the syntactic and semantic properties of Short Form Confirmatives(SFC's) and the functions of negative 'an' occuring in SFC's in Eastern Chonnam Dialect. Although the syntactic forms of SFC's are the same as of negative interrogatives, the function of SFC's is to provide an affirmative proposition to listener to confirm certain events or situations. The pragmatic affix 'an' of SFC's means that speaker's supposition is not in accordance with the actual situation in a given conversation There are several types SFC's with a marked type having two or more 'an's' in a single sentence, and no other 'an's'.

각종 악성종양질환에서의 세포면역 기능에 대한 연구 : 말초 혈액 T 임파구 아형 분포 및 지연형 과민반응에 대한 검색 Delayed Cutaneous Hypersensitivity and Peripheral Blood T-lymphocyte Subsets

송재화,이복희 충남대학교 의과대학 지역사회의학연구소 1987 충남의대잡지 Vol.14 No.1

The author studied delayed cutaneous hypersensitivity and peripheral blood T-lymphocyte subpopulations in 54 patients with malignant tumors. 1. The number and total score of positive reactions in delayed cutaneous hypersensitivity were significantly decreased in cancer patients(p<0.005, p<0.05). 2. Percent OKT4^+ T-lymphocyte in cancer patients were significantly decreased compared to normal control subjects (p <0. 05), and it had positive correlation with total score of delayed cutaneous hypersensitivity reactions(r=0.768). 3. Percent OKT8^+ cells were not different from that of normal control subjects. 4. The ratio of OKT4^+/OKT8^+ in cancer patients were not different from that of normal control subjects except in patients with colorectal carcinoma and malignant lymphomas. 5. Markers of activated T-lymphocyte, OKT10^+ and OKIal^+ cells were increased in all the patient groups. 6. Leu7^+ cells, reflecting natural killer cells, were not different from normal control subjects These results suggest that the cancer patients have depressed cellular immune functions, which mainly results from the decrease of helper T lymphocyte number. Short of functional assays of cellular immunity, the author concluded that the testing of delayed cutaneous hypersensitivity and enumeration of peripheral blood lymphocyte subsets, especially OKT4^+ cells and activated T cells provide useful informations on cellular immune reactivity in cancer patients. Further studies on prognostic value of these parameters should be pursued.

In 1965 Lauren divided advanced gastric carcinoma into two main types-namely, "intestinal" and "diffuse" type carcinoma, which differ not only morphologically but also in their clinical and epidemiological characteristics. Moreover, a different histogenetic process has been postulated by many authors that intestinal type gastric carcinoma might arise from areas with intestinal metaplasia. Since Warren and Marshall reported the presence of Helicobacter pylori in the stomach in 1983, strong evidence has been obtained that there is a close relationship between Helicobacter pylori and chronic gastritis, atrophic gastritis, intestinal metaplasia, and intestinal type gastric carcinoma. To study the relationship between intestinal metaplasia and Helicobacter pylori infection, we performed gastroscopic biopsies and CLO tests taken from patients with epigastric pain. Only 87 patients with macroscopically suspected antral gastritis were included. The prevalence of intestinal metaplasia in gastric antral biopsies increased from 33.3% in the age group<30 years to 63.6% in the age group 60 years. When all patients were divided into two age groups-namely, (i)<50 years(n=41) and (ii)≥ 50 years(n-=46), intestinal metaplasia was found significantly more often in patients ≥ 50 years. ((i) 39.2%, (ii) 54.3%, p<0.0001). The prevalence of Helicobacter pylori in gastric antral biopsies decreased from 66.7% in the age group<30 years to 62.5%, in the age group in the age group 50 to 59 years. When all patients were divided into the same two age groups-namely(i)<50 years and (ii)≥50 years, the prevalence of Helicobacter pylori did not differ between two groups in a statistically significant way. The mean age of intestinal metaplasia positive patients who were also Helicobacter pylori positive was 48±11.0(mean±S.D.)years, whereas the mean age of intestinal metaplasia positive patients who were Helicobacter pylori negative was 52±9.7(mean±S.D.)years. In conclusion. although our data do not prove a causal relationship between Helicobacter pylori infection and the histogenesis of intestinal metaplasia, we suggest that Helicobacter pylori plays an important role in the development of intestinal metaplasia in the gastric mucosa. Whether Helicobacter pylori has to be present at all times during this process or is only necessary as a 'trigger', needs further research.

K_(2)SnCl_(6)는 antifluoride계에 속하는 결정으로서 K_(2)SnCl_(6)에 Li^(+)를 첨가하여 ^(7)Li 핵자기공명(NMR)을 측정하여 동형(isomorphic) 혼합결정(K_(1-x)Rb_(x))_(2)SnCl_(6)와 비동형(nonisomorphic) 혼합결정 K_(2)SnCl_(6):Al^(3+)에서의 핵자기공명(NMR), ^(87)Rb NMR과 ^(27)Al NMR의 측정값과 비교하였다. Rb^(+) 이온은 K_(2)SnCl_(6)의 K^(+)이온을 대신해 동형 결정을 이루며, Al^(3+)이온은 Sn^(4+)이온을 대치하면서 비동형 결정을 이루는데 Li^(+)이온 또한 K^(+)이온을 대신하는 동형 혼합결정과 유사한 결과 값을 얻을 수 있었다. 이 연구 결과는 종래의 Cl-NQR 연구 결과와 비교함으로서 K_(2)SnCl_(6)의 동력학적 특성과 구조 상전이 근처에서의 임계현상을 새로운 관점에서 볼 수 있는 가능성을 보여주었다. ^(7)Li, ^(87)Rb and ^(27)Al NMR have been investigated in the isomorphic and nonisomorphic impurity doped crystals (K_(1-x)Li_(x))_(2)SnCl_(6), (K_(1-x)Rb_(x))_(2)SnCl_(6) and K_(2)SnCl_(6):Al^(3+) as a supplementary to the previous Cl NQR studies in these crystals. The results yielded that the features of NMR spectra for both types of crystals are roughly in line with the systematic trends shown in the Cl NQR in these crystals, though the outstanding characteristics exhibited in the Cl NQR become in the case of the NMR of the doped impurities in crystals somewhat weakend. This is due to the degradation of the role of the local field from the main hamiltonian in NQR to the subsidiary in NMR. Each NMR result of the iso/nonisomorphic crystals has been analyzed in terms of the 'impurity induced dynamic lattice defects' for K_(2)SnCl_(6):Al^(3+) and the 'static primary impurity effects' for (K_(1-x)Rb_(x))_(2)SnCl_(6) and (K_(1-x)Li_(x))_(2)SnCl_(6) respectlvely.
