The fusion cross sections induced by heavy-ions are formulated in detail in the basis of the customary barrier penetration model with the incoming wave boundary condition. The theory is applied to the ^12C+^16O system at low energies and explains well the observed fusion data as well as the elastic scattering.

This study was made to investigate the degree of rice blast disease developing in various plants and also the relationship between the disease developing and the amount of content of nutrients in rice plants which were differently dressed. Possibility for culture of rice-blast race was studied and the structure of infected leaves were observed by electron microscope. 1) The varieties sampled, Pung-kwang, Jin-heung, Pal-tal, Pung-ok and Tong-il, were seeded and cultivated in pots. When fifth or sixth leaf emerged, the races of blast T,C,N were innoculated in all varieties. In dressing test Pung-ok, which leas susceptible to blast, was dressed with nitrogen fertilizer in ordinary and twofold and in none-dressing or dressing of silicon fertilizer. When the fifth or sixth leaf was appeared, races T, C, N was innoculated in each varieties of pot. In all experiment the degree of infection was checked out according to the order of leaf, and at the same time, the relationship between the degree of disease developing and the contents of nutrients by determining the total nitrogen, total sugar, phosphoric acid, kalium, silicon dioxide soluble nitrogen and soluble sugar was studied. The occurance of symptom was relatively frequent in upper primary or secondary leaf in all varieties regardless of the kind of fertilizers or their dressing amount. Comparing the occurrencies of disease development in examined varieties, Jin heung was lowest and Pung-ok was highest, while Tong-il was completely free from the infection of the disease. The race T-type attacked most seriously the varieties of Jin-heung, Pal-Tal and Pung-kwang except Pung-ok, C-type was moderate and N-type was very weak in Pung-ok. In the amount of dressing, the occurance of disease was very rare in the rice plant of N-ordinary-silicon fertilizer dressed and frequent in that of nitrogen fertilizer-twofold-and-silicon fertilizer none dressed. The disease developing differed with the races, indicating T-type was most poweful, C-type moderate while N-type was weak. In the interaction between the contents of nutrients in riceplant and the degree of disease developing, Pung-ok, which was very abundant in nitrogen, phosporic acid, glutamic acid, asp artic acid glutamine, asparagine, cystine, serine and sucrose but little in sugar, kalium and silicondioxide, was most susceptible to the disease. Jin-heung, resistant one, was opposite to Pung-ok in all aspects. As a result there was a correlation between the kind or amount of nutrients in rice plant and the disease attack. According to the amount of dressed fertilizer, the rice plant dressed in N-twofold and silicon dioxide none dressed had the larger amounts of total nitrogen, phosphoric acid, aspartic acid, glutamic acid and gldtamine but little in sugar and silicon dioxide contents. While in the rice plant dressed with N-ordinary and silicon fertilizer. the tendancy of disease occuring was low respectively. 2) The study on the cultivation of race T,C,N in the media added such organic acid as succinic acid, valeric acid, malic acid, ketoglutaric acid and such phenolic chlorogenic acid and salicylic acid was made. The result of which was as follow: ① There were no differences in growth of T,C,N type races. ② In the media added organic acid the growth was favorable. ③ In the media added chlorogenic acid the growth was promoted but in the one added salicylic acid the growth was inhibited. 3) The morphological changes of the infected waves alls the structure of hypha of blast which had penetrated into the leaf cell of Pung-ok, which was susceptible one to the disease, was observed by electric microscope. The following facts were found. ① In healthy leaves normal nucleus, mitohcondria, chloroplast, entoplasmic reticulum, vacuole and cytoplasm, especially round substances, were chearly observed by electron microspcope. ② In the infected leaves, the space of the nucleus double memberance was enlarged, and some of the nucleu walls were destroyed. The thinlayer structure of glanalamelae in lamela system was enlarged, somewhere spates were appeared while stromas were disappeared. In mitochondria the spaces of the double membrance were enlarged. ③ Cytoplasm of cell which were attacked by hypha was completely destroyed and the hypha lost their normal structure. ④ In the structure of hypha which penetrated into the cell wall of epidermis, nucleus, mitochondria, round ectoplasmic reticulum, vacuole and substances were clearly observed.

In order to investingate the effectiveness of measurement of zinc protoporphyrin(ZPP)in whole blood in the health provision of lead workers, 344 make lead workers working in 4 different lead using indrstries were selscted. The parameters chosen for this study were ZPP in whole blood, blood lead(PBB), ∂-aminolevulinic acid in urine(ALAU), hemoglibin(HB), work duration of each workers & their working condition. The results obtained are as follows : 1. Blood ZPP was highly correlated with blood lead among various indices of lead absorption. The was no difference of correlation coefficient between ZPP & LOGZPP with blood lead. 2. The regression equation of LOGZPP on blood lead (PBB) was LOGZPP = 2.61 +0.047PBB 3. The slope of regression of LOGZPP on PBB of longer work duration was steeper than that of short work duration group. This could be explained by the chronic effect of lead on heme precursors. 4. It is highly recommended that blood ZPP could be used as a screening index of biological monitoring of lead workers.

To study the relationship between the urinary hippuric acid and subjective symptoms in toluene exposed workers, urinary hippuric acid was measured and subjective symptoms questionnarire was surveyed in 93 toluene exposed male workers and 96 non-exposed office male workers. The results are as follows: 1. Mean concentration of urinary hippuric acid, which is significantly higher in exposed group than in non-exposed group, was 1.3 g/1, 1.2(GM, GSD respectively) in exposed group and 0.6 g/1, 1.2(GM, GSD respectively) in non-exposed group. 2. Mean concentration of toluene in the air in the workplace, which is significantly higher in the department of coater than in the department of mexing, was 23.4 ppm, 6.2(GM, GSD respectively) in the department of mixing and 59.8 ppm, 3.4(GM, GSD respectively) in the department of coater. 3. Complained rates of subjective symptoms were significantly higher in exposed group than in non-exposed group in all items. 4. In exposed group, complained rate of CNS related symptoms was higher than that of irritation ralated symptoms in the first part but there was no significant difference and complained rate of irritation related symptoms in the second part was significantly higher than that of CNS related symptoms. 5. In exposed group, complained rates of subjective symptoms were not compatible with dose-response relationship by the concentration of urinary hippuric acid, duration of work, department of work, and age group retrospectively.

Kyu Taik Sung(成圭鐸) 한국노년학회 1989 한국노년학 Vol.9 No.1

This paper presents results of the analysis of 817 stories about Koreans who have exemplified filial piety. Corollaries of filial piety were identified, e.g., types of care and services provided to elderly parents, motives for filial piety, kinds of emphasis given in filial duties, sacrifices endured for parents and related subjects. The most outstanding dimensions underlying filial piety were 'respect', 'responsibility', 'harmonious family' and 'sacrifice'. Findings provide us with conceptual as well as practical tools for understanding and practicing family-centered filial piety.

한국인의 효행의지와 연령층들간의 차이

성규탁(Kyu-taik Sung) 한국노년학회 1995 한국노년학 Vol.15 No.1

4개 연령층으로 이루어진 1,818명을 대상으로 효행의지를 중요시하는 정도, 이를 중요시하는 정도의 연령층들 간의 차이, 동일 연령층에 속하는 자녀들이 효행이유를 중요시하는 정도, 기타 연령층과 관련된 부모부양에 대한 사항들을 조사하였다. 모든 연령충의 응답자들이 대 다수 유형의 부양의지를 중요시했다. 교육정도가 높을수록 이를 더 중요시했고, 연령이 높을수록 부양의식에서 더 전통지향적인 성향을 나타냈다. 젊은 층은 연상층보다 더 변화지향적인 성향을 보였고, 연령차가 많을수록 효행의지를 중요시하는 정도에 차이가 컸으며, 세대가 인접할수록 그 차이가 적었다. 동시에 젊은 층과 연상층간에는 효행의지를 중요시하는 정도에 유사성과 지속성이 있음이 시사되었다. 이러한 결과는 사회가 변하고 세대가 달라지고 있지만 전통적 부모부양 이념과 관행은 성인자녀들 간에 긍정적으로 인식되고 있음을 시사한다. 즉 전통의 타성은 지속되고 있다는 것이다. Willigness to care for parent was assessed in terms of a set of 13 filial piety items based on data obtained from a random sample of 1, 818 pre-adult and adult children comprising four age groups. The degrees to which the children gave importance to the filial piety items and differences between age groups in terms of the degrees were examined. Findings suggest: the higher the degree of educational attainment, the greater the importance given to the items: the greater the age difference, the greater the difference in the degrees of importance given to the items. And the older children tended to be more traditional value oriented while the younger tended to be less so. Amids these differences, a strand of similarity interwound with continuity existed between age groups; all groups gave importance to almost all the filial piety items and differences between any adjacent age groups were small. Findings suggested that traditional ideals associated with parent care were being retained and taken seriously by modern Koreans, and that the inertia of the cultural tradition hanged on.

A NEW LOOK AT IDEALS AND PRACTICES OF FILIAL PIETY : THE CASE OF EXEMPLARY FILIAL PERSONS

Sung, Kyu-Taik,Song, Bok 연세대학교 동서문제연구원 2001 Global economic review Vol.30 No.3

The definition of filial piety has become a public issue in Korea because of the significant impact filial piety has on the welfare of the elderly as on the morality of the young. The study explored how filial piety is practiced in Korea. Compiled from three national institutions awarding filial piety prizes in Korea, stories about Korean adults who had exemplified filial piety during the recent two decades are analyzed using the content analysis method. As a result of this analysis, a set of eleven indicators of filial piety emerged, including respect for parents, filial sacrifice, etc. The fundamental value of filial piety is still under preservation even while its manifestation is changing in modern times. These indicators will be useful in understanding the concept of filial piety and constructing a measure that might be used to assess caring relationships between adult children and elderly parents.
