김영남 ( Young Nam Kim ),송윤신 ( Yun Sin Song ),김윤신 ( Yun Sin Song ) 한국치위생학회 2012 한국치위생학회지 Vol.12 No.1
Objectives : By analyzing the affects of the mother`s oral care to the caries experiences of the elementary school children, To looking for the way to prevent dental caries in the primary school, to provide baseline data to perform the associated oral health education. Methods : Between the 3,676 children`s dental check-up data and the 2,934 survey of parents from 9 elementary schools in the the Gyeonggi Province, the exactly matching data of 2,358 pairs, children versus mothers, were analyzed during the period, 2009 May 4 to July 20, By using the PASW 18(SPSS-PC 18), Frequency analysis of the collected data, and cross-analysis, ANOVA, Bonferroni post-analysis was performed. Results : The findings of the study were as follows. 1. In children, the ratio(DMF rate)of the dental caries experience in permanent teeth, appeared higher for men than women. Divided by grade level, the ratio of caries experience in the permanent teeth(DMF rate) generally appear higher in older than young. Thus between the child`s gender and grade level by the ratio of caries experience in the permanent teeth(DMF rate) showed the statistically significant differences (p<0.05). 2. Between the socioeconomic characteristics of mothers and the children`s level of dental caries experiences, not showed the statistically significant difference.(p>0.05). 3. The significant difference showed between the dental caries levels of the children and the mother`s oral health care behavior - a toothbrush replacement period, mother`s broken teeth, mothers guidances of the brushing after snacks for children(p<0.05). Conclusions : The mother`s oral health attitudes and behaviors can affect to their children`s oral care habits. Therefore The mother themselves should have the right proper habit of oral health care, so that in oral health care mothers should be the model for their children. Institutionally more systematic and detailed oral health educational program in conjunction with the family is needed.(J Korean Soc Dent Hygiene 2012;12(1):145-156)

BACKGROUND: Globally, large amounts of phosphogypsum (PG), which is a by-product of the phosphate fertilizer production, is deposited in open areas. As PG contains calcium, phosphate, and sulphate, it can be used as a soil amendment in farmlands. This study was conducted to investigate the effects of PG application on properties of field soil and yield and quality of garlic (Allium sativum L.), and to seek appropriate level of PG application into the field. METHODS AND RESULTS: This experiment was conducted by applying PG at four different levels that were adjusted based on 65% calcium base saturation in the field soil: 0% (control), 50% (PG50, 100 kg/10a), 100% (PG100, 200 kg/10a), and 150% (PG150, 300 kg/10a). Following cultivation, soil electrical conductivity (EC), organic matter, available P and exchangeable Ca increased, whilst soil pH decreased. With increase in PG application level, soil EC and exchangeable Ca increased. PG application increased concentrations of water soluble Ca and SO4 across the soil profile, especially in PG150. The highest yield of garlic was found in PG100 treatment. The plant's uptake for N, P, Ca, and S increased by PG applications, but that for K decreased. Moreover, concentrations of S-related amino acids such as cysteine and methionine in garlic increased by PG applications. The increased content of nutrients and amino acids with PG supply might improve yield, quality, and favor of the crop. CONCLUSION: Overall, PG application at 200 kg/10a into a field had the best effect on improving soil fertility as well as yield and quality of garlic. Further studies are required to maximize efficiencies of PG supply in soil management and production of various crops.

토양 견밀도가 (堅密度) 수목생장에 미치는 영향 - 어린이대공원 수목관리를 중심으로 -

Diameter growth was surveyed for 22 years-old pitch pine (Pinus rigida Mill.) growing on the forest land (site protected from artificial damage) and the resting place (site open for the recreation) of the Children Park, Seoul, Korea on September 28, 1975. The purpose of the survey was to find out difference in the tree growth between the two sites, and possible causes of the difference. Both the resting place and the forest land have deep fertile sandy-loam soil, moderate slope for south-west. The resting place, however, has much higher soil compactness by treading than the forest land. Before May 5, 1973, the opening date of the park, the trees on the resting place had higher diameter growth than those on the forest land as measured with increament borer. After the Park opening the trees on the resting place showed less growth than those on the forest land. In 1975, the growth on the resting place was less than that of the forest land by 6.5% at 1% significant level. The difference in growth was attributed to the soil compactness of the resting place by treading. The necessity for the same kind of study with other species for the tree management of parks was suggested.

G. M. 홉킨스의 「농부 해리」와 「톰의 영관」: 형식과 상징적 연관성
김영남 ( Young Nam Kim ) 충북대학교 인문학연구소 2011 人文學誌 Vol.43 No.-
This essay aims to examine the formal and symbolic link between G. M. Hopkins` sonnets, Harry Ploughman and Tom`s Garland. These sonnets which Hopkins produced nearly at the same time show very similar qualities in their form and subject. First, they are similar in that they employed the caudated lines, or burden-lines, which deviate greatly from the conventional Italian sonnet form. This formal deviation is a deliberate invention by the poet, who intended his sonnets to be recited aloud almost like a musical piece. This intention unavoidably led him to add extra lines like musical burdens. Second, both sonnets are similar in that they suggest Hopkins` socio-political idea of a healthy society or nation. It is very unusual in his poetic career that the poet deals with the contemporary socio-political problems like unemployment and social unrest in England. Ostensibly, the two sonnets seem to represent two different aspects of an English low life, but actually they have a complementary symbolic link as they get the readers to see what an ideal state of the body-politic should be.

산화분위기에서의 Ti/SiO₂ 박막의 산화거동 및 계면반응을 조사했다. SiO₂막위에 100㎚의 티타니움을 스퍼터법으로 형성하여 급속가열로(Rapid Thermal Processor)에서 온도를 달리하여 산화시켰다. 산화거동은 박막의 면저항의 측정, 산화막 두께측정, XPS(X-ray Photoelectron Spectroscopy)에 의한 조성분석으로 평가했다. 산화시 티타니움 면저항은 표면에서 산화로 인해 약 500℃ 이상에서 증가하기 시작해서 800℃에서 포화되었다. 이 때 막두께는 약 700℃ 이상에서 약 2배로 증가한 후 일정한 두께를 나타내었다. 이 결과로부터 산화부산물에 도전성물질이 존재하는 것을 알 수 있었다. TEM과 XPS분석결과 400℃ 이상에서 산화시 Ti 표면에서부터 TiO₂가 형성되고 600℃이상에서는 TiO₂와 SiO₂의 계면에 TiO_x의 형성과 Si의 석출이 확인되었다. 석출되는 Si의 양은 온도에 따라 증가했다. The oxidation behavior of the titanium film and the interface between titanium and underlying SiO₂ were investigated. The titanium film, 100 ㎚ thick, sputtered on the SiO₂ film was oxidized at different temperatures using rapid thermal processor (RTP). The oxidation behavior was evaluated by the contactless resistivity measurement and measuring the thickness of the oxidized film. X-ray photoelectron spectroscopy (XPS) was performed for composition analysis of samples. The sheet resistance of the oxidized Ti film increased with oxidation temperature above 500℃ and saturated at 800℃. The oxidized film thickness also increased with temperature, and become about 2 times of orignal thickness of the Ti film above 700℃. This might indicate that conducting oxide film (TiO_x) was formed during oxidation. According to TEM observation and XPS analysis, the Ti film was oxidized above 400℃ from its surface. When it was oxidized above 600℃, the formation of TiO_x and the precipitation of Si occurred at the interface between TiO₂ and SiO₂. The amount of the precipitated Si increased with temperature.
